[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tube container of a type including at least one deformable tubular member for containing a distribution product, which is used for distributing a fluid product such as a cosmetic, and the tubular member has one end closed and the other At the end is a spout that allows the contents to be taken out by pressing the tubular member. More specifically, the present invention relates to a tube container in which a check valve for shutting off outside air is provided in a pouring passage that communicates the inside and the outside of a tube filled with contents.

[0002]

[Prior art]

 This type of tube container is well known and is often used to sell various fluid products such as toothpaste and cosmetics. Due to the material used to construct the tube container, the tube container undergoes plastic deformation and elastic deformation when the member is crushed to pour out the contents.

In the first case, ie when undergoing plastic deformation, air is not drawn into the interior of the tube container, but the tube container is gradually deformed as its content decreases due to its plastic deformation. It has a poor appearance. In the second case, i.e. when subjected to elastic deformation, the tube container, due to its elasticity, regains its original form as soon as the pressure applied to crush it relaxes. Therefore, in this second case, the original appearance is always restored, but the air sucked inside may come into contact with the contents in the tube container and cause deterioration of the contents as a product due to, for example, oxidation. Absent. Furthermore, since air enters the tube container, the amount of contents that can be poured out each time new is poured out is determined by the user in advance while pressing the tube container and at what flow rate of the contents from the spout. Vary unless you know what.

On the other hand, the tube container should be provided with at least two deformable tubes in order to squeeze out at least two kinds of contents, which should be kept separate from each other until it is poured from the tube container. Has already been proposed. However, such a multiple-type tube container has the same problems as those of the single-type tube container.

Therefore, conventionally, in the second case where the appearance can be maintained well, that is, in the case of a tube container configured to be elastically deformable, a reverse process for preventing outside air from entering the tube and oxidizing the contents is reversed. Tube containers with stop valves have been devised.

Particularly in the case of a two-color tube container, as shown in FIG. 18, an inner sleeve 2 is concentrically arranged inside an outer sleeve 1 which forms a body, and A shunt piece 3 is integrally formed on the neck of the sleeve 2, and the shunt piece 3 is fitted into the outer sleeve 1 to fill the contents between the sleeves 1 and 2 and the inside sleeve 2 separately. A check valve 6 that opens when the contents are pushed out from the inside of the container is provided in each of the contents passage 4 between the two and the contents passage 5 of the inner sleeve 2. When the outer sleeve 1 of the tube container is pressed, the check valve 6 opens as shown in FIG. 19, and the contents of the inner sleeve 2 and the contents between the sleeves 1 and 2 are separated from each other by the flow dividing piece 3. Be poured through.

Further, as shown in FIG. 20, when the tube container is released from the pressure after the contents are pushed out, the check valve 6 is closed by the restoring force of the tube container and the flow of the contents between the sleeves 1 and 2 is stopped. The passage 4 and the flow passage 5 for the contents of the inner sleeve 2 are closed to prevent outside air from entering the tube container, thereby preventing the contents from being oxidized and the contents of the two chambers from being repeatedly used. It is evenly poured.

In addition to this, as a two-color tube in which a check valve is provided in a pouring passage that communicates the inside and the outside of the tube, Japanese Utility Model Laid-Open No. 59-121358 and Japanese Utility Model Laid-Open No. 62-78644, There is Japanese Patent Publication No. 63-42336.

[0009]

However, in the above-mentioned tube container, when the sleeves 1 and 2 are restored after the contents are pushed out as shown in FIG. 21, the check valve 6 is closed. There was a problem that the tube container became deflated, and the appearance was very poor, as in the first case.

The present invention relates to a tube container of the type having at least one deformable tube for distributing at least the fluid product which is the contents, and the tube container of the present invention is a container for the contents already used. The feature is that the appearance is always maintained regardless of the quantity. The invention further aims at providing a tube container of the type in which the contents can be immediately and easily dispensed as much as necessary if the user presses the tube. The present invention further relates to the provision of a tube container of the type capable of simultaneously extruding at least two types of fluid in easily adjustable amounts. The invention also relates to the provision of a tube container of the type that does not come into contact with the ambient atmosphere until one or more contents have been poured out. Specifically, even if the check valve is closed to prevent outside air from entering the tube to prevent oxidation of the content when the tube is released from the pressure after the content is pushed out. The purpose is to provide a tube container that can maintain a good appearance.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The tube container 101 as shown in FIGS. 1 and 2 is used for distributing an arbitrary amount of a fluid product such as cream or putty. The tube container 101 has an inner tube or tubular member 102 that is surrounded by an outer tube 103 at intervals.

The inner tube 102 is composed of a cylindrical wrapping bag 104 made of a synthetic resin material, one end of which is pressed and closed 105 by welding, for example. The other end of the bag 104 is connected to a discharge nozzle 107 having a discharge hole 108 via a neck 106.

The outer tube 103 is also composed of a cylindrical wrapping bag 109 made of a synthetic resin material, one end of which is pressed and closed 110 by welding, for example. The other end of the packaging bag 109 is connected via a neck 111 to a discharge nozzle 112 having a discharge hole 113 in which the nozzle 107 of the inner tube 102 is fixed. The nozzle 112 of the outer tube 103 has threads 114 for a screw cap 115 on its outside (FIG. 1).

An air circulation hole 116 is formed in the neck portion 111 of the outer tube 103, and the hole 116 allows an intermediate space between the tubes 102 and 103 to freely communicate with the atmosphere.

It should be noted that the outer tube 103 is composed of a wrapping bag 109 that is thicker than the wrapping bag 104 of the inner tube 102.

Since the inner tube 102 is filled with the fluid, the user twists and opens the cap 115 and pushes the outer tube 103 in the direction of pressing in order to dispense the content once. Since the holes 116 are formed, the air between the tubes 102 and 103 is pushed by the mechanical contact due to the pressure exerted by the user on the outer tube 103 when the outer tube 103 contacts the inner tube 102. To the outside, so that the amount of contents desired by the user is squeezed out from the discharge holes 108, 113.

Once the desired amount of content has been extruded, the user ceases to press against the outer tube 103 and the inner tube 102 either returns to its original configuration, depending on whether it is elastic or not, and if so, A corresponding amount of air enters the inner tube 102 through the exhaust holes 108. The elastic outer tube 103 regains its original shape by itself, and the holes 116 in the outer tube 103 always allow a pressure balance between the atmosphere and the air between the two tubes 102, 103. As a result, a negative pressure that could prevent the outer tube 103 from recovering to its original configuration can never occur between the tubes 102, 103.

The tube container 101 shown in FIG. 3 differs from the embodiment of FIG. 2 in that the outer tube 103 further surrounds the first inner tube 117 surrounding the second inner tube 118 from the outside.

As in the case of the embodiment shown in FIG. 2, the outer tube 103 has an elastic material in which one end is squeezed closed 110 by, for example, welding, and the other end is connected to the nozzle 112 having the outer screw 114 formed at the neck 111. It is composed of a packaging bag 109. In this case, the nozzle 112 has a pair of discharge holes 119 and 120 arranged in parallel.

The first inner tube 117 is composed of a packaging bag 121 made of an elastic material, one end of which is pressed and closed 122 by welding, for example. The other end of the first inner tube 117 is connected to a nozzle 124 having two discharge holes 125 and 126 by a neck portion 123, and the nozzle 124 has both discharge holes 125 and 126 which are holes of the nozzle 112 of the outer tube 103. 119 and 120 are inserted or fixed in the nozzle 112 of the outer tube 103 so as to be aligned with the openings 119 and 120 and open to the inside.

The check valves 127 and 128 are provided at the outlets of the discharge holes 125 and 126 of the nozzle 124, and the valves 125 and 126 open outward due to the pressure difference and close if there is no pressure difference.

The second inner tube 118 is formed of a wrapping bag 129 made of an elastic material, one end of which is pressed and closed 130 by welding, for example. The other end of the second inner tube 118 is connected to the nozzle 132 having the discharge hole 133 at the neck 131. The nozzle 132 is inserted or fixed in the nozzle 124 of the first inner tube 117 so that the discharge hole 133 is in series communication with the discharge hole 126 of the nozzle 124.

Further, the outer tube 103 has a hole 134 communicating with the outside air in the neck portion 111 thereof, and the air flow to the hole 134 is adjusted by the check valve 135 so that the outer tube 103 can communicate from the outer side to the inner side. However, it is impossible to communicate in the opposite direction.

The first fluid is enclosed within the second inner tube 118 and the second fluid is between the first inner tube 117 and the second inner tube 118. It is enclosed in 117.

The wrapping bags 121 and 129 of the both inner tubes 117 and 118 may be flexible, that is, wrapping bags having extremely small elasticity or slightly wrapping, while the wrapping bag 109 of the outer tube 103 is elastic. It is composed of a wrapping bag that has a certain property, that is, an elastic restoring force. For example, as shown in the drawing, the three tubes 103, 117, 118 can be formed of the same elastic material packaging bag, and the packaging tube 109 of the outer tube 103 in this case is a packaging bag 121 of both the inner tubes 117, 118. , 129, which is thicker than 129.

Since both inner tubes 117 and 118 are filled with respective fluids, in order to push out both kinds of contents at the same time, the user twists off the cap 115 from the nozzle 112 and compresses it into the outer tube 103. Apply directional pressure. The valve 135 is closed, trapping air between the outer tube 103 and the first inner tube 117 and completely blocking its outflow, so that this air is compressed and squeezes the first inner tube 117 and thus the first inner tube 117. The contents of the first inner tube 117 are squeezed to compress the second inner tube 118. Due to the compression of both inner tubes 117, 118, both contents in both inner tubes 117, 118 are separated by one through holes 125, 119 and the other by holes 133, 126, 120. It is extruded through two valves 127 and 128 which are opened by the pressure of the fluid.

When both contents have been pushed out by the required amount, the user stops pressing the outer tube 103. The elasticity of the outer tube 103, which has been pressed until then, restores its original shape to eliminate the pressure that has been working in the inner tubes 117 and 118, so that both valves 127 and 128 are closed. At the same time, the outer tube 103 creates a negative pressure in the space between the outer tube 103 and the first inner tube 117, so that the valve 135 opens and through the hole 134 in the direction of pressure balance with the atmosphere. Atmosphere is introduced into the space. This pressure balance continues until the outer tube 103 regains its original configuration, after which the valve 135 closes.

Therefore, the tube container 101 is in a state in which both kinds of contents contained in the inner tubes 117 and 118 can be newly pushed out.

Since the two check valves 127, 128 are provided in the discharge holes 125, 126 of the two inner tubes 117, 118, no air can flow into the inner tubes 117, 118 at all, and There is no contact with the contents in both inner tubes 117, 118. As a result, the inner tubes 117 and 118 are gradually deformed as their contents are pushed out. On the contrary, the outer tube 103 always recovers its original form, that is, each time the pressure is released, a quantity of air corresponding to the quantity of the contents that has been poured out flows in, and this air is due to the valve 135. And is contained within the outer tube 103. Therefore, the pressure exerted on the outer tube 103 immediately extrudes both contents with a proportional flow rate. For this reason, the amount of contents dispensed is extremely accurate.

Of course, within the scope of the invention, it is possible to combine some or all of the features mentioned in the above two embodiments in a tube container.

Thus, for the tube container 101 for a single type of content shown in FIG. 2, for example, a check valve in the single outlet 108 of the inner tube 102 and / or the outer tube 103. A check valve may be provided in the hole 116 of the. Similarly, the check valve 135 in the hole 134 of the outer tube 103 of the two-type tube container 101 shown in FIG. 3 is eliminated, and the intermediate space between the two tubes 103 and 117 communicates freely with the atmosphere, and It is also possible for the inner tubes 117, 118 to be compressed by mechanical contact after compression of the outer tube 103.

On the other hand, FIG. 4 shows a tube container according to a third embodiment of the present invention. This tube container is composed of a concentric inner tube 10, an outer tube 20, and a valve body 40.

The inner tube 10 is roughly divided into an inner sleeve 11 that forms a container for cosmetics and the like, a neck portion 12 having a smaller diameter than the inner sleeve 11, and a shoulder portion 13 that joins the inner sleeve 11 and the neck portion 12 together. Has become. On the outer peripheral surface of the neck portion 12, two annular convex portions 14 and 14 for securing engagement with an outer tube 20 described later are formed, and a spout 15 is opened on the top surface thereof. . Further, a positioning rib 16 is formed on the lower portion of the outer peripheral surface of the neck portion 12.

The outer tube 20 is roughly divided into an outer sleeve 21 that forms a storage portion for cosmetics and the like, a neck portion 22 having a smaller diameter than the outer sleeve 21, and a shoulder portion 23 that connects the outer sleeve 21 and the neck portion 22. Has become. Air holes 24 are formed in the upper surface of the shoulder portion 23. A thread 25 for screwing a lid (not shown) is formed on the outer peripheral surface of the neck portion 22. A spout 26 is provided on the top surface of the neck 22, and a check valve 28 is provided below the inner peripheral surface of the neck 22 via a hinge 27. Further, on the inner peripheral surface of the neck portion 22, two annular recessed portions 29 for closely fitting the annular convex portion 14 of the neck portion 12 of the inner tube 10 are formed in the circumferential direction. An alignment groove 30 is formed in the. It should be noted that the annular convex portion 14 and the annular concave portion 29 may be provided as necessary, and need not necessarily be formed in an annular shape.

As shown in FIG. 7, the valve body 40 is a soft plastic annular seat having two flanges 41, 41, and alignment recesses 42, 42 are formed on the inner peripheral surface thereof. ing. The valve element 40 is positioned by the alignment rib 16 of the inner tube 10 and is set so that the air hole 24 of the outer tube 20 is closed by either one of the two flanges of the valve element 40. The material of the valve element 40 is not particularly limited as long as it is a thin sheet.

The positioning ribs 16 of the inner tube 10 configured as described above are covered with the positioning recesses 42 of the valve body 40. Next, the positioning ribs 16 of the inner tube 10 are positioned by aligning the positioning ribs 16 of the inner tube 10 with the positioning recessed grooves 30 of the neck portion 22 of the outer tube 20, and the annular protrusion 14 and the annular projection 14 are annularly sandwiched. The neck portion 12 is fitted to the neck portion 22 by tightly fitting the concave portion 29. Finally, the inner tube 10 is filled with the contents, and the bottom portion is also fused with the bottom portion of the outer tube 20 so that an air chamber is formed between the inner tube 10 and the outer tube 20 which form the tube container. .

When the outer sleeve 21 of the outer tube 20 of the tube container thus formed is pressed with a finger, the valve body 40 closes the air hole 24 of the outer tube 20 due to the pressure in the air chamber, so The pressing force is transmitted as it is to the inner sleeve 11 of the inner tube 10 to pressurize it, and the content rises and is discharged from the spout 15, and the check valve 28 is pushed up via the hinge portion 27 of the outer tube 20. The contents can be extruded from the spout 26.

When the outer tube 20 is released from the pressure after the content is pushed out, the check valve 28 closes due to the decrease in the inner pressure of the inner sleeve 11 of the inner tube 10, and the outside air flows from the spout 15 to the inner tube 10. It prevents entry and thus acidification of the contents, but leaves the inner tube 10 in a deflated state. On the other hand, in the outer tube 20, the valve body 40 closing the air hole 24 is displaced downward due to the pressure difference between the inner and outer sides due to the restoration of the outer sleeve 21 and the air hole 24 is opened, so that the outside air is prevented from flowing inside and outside By sucking into the air chamber between the tubes 10 and 20, the appearance before pressing can be restored. Therefore, the appearance does not deteriorate even when the check valve 28 for preventing the oxidation of the contents is closed and the inner tube 10 is shrunk.

As shown in FIG. 5, the outer tube 50 is roughly divided into an outer sleeve 51 and a neck portion 52 having a diameter smaller than that of the outer sleeve 51, and an outer sleeve 51 and a neck portion 52. It is formed of a shoulder portion 53 to be joined. An air hole 54 is bored in the shoulder portion 53. A positioning groove 55 is formed in the lower portion of the inner peripheral surface of the neck portion 52, and an eave-shaped protrusion 56 is formed in the upper portion of the inner peripheral surface.

As shown in FIGS. 6 and 9, the inner tube 60 is roughly divided into an inner sleeve 61 that forms a storage portion for cosmetics and the like, a neck portion 62 having a diameter smaller than that of the inner sleeve 61, and an inner portion. It comprises a sleeve 61 and a shoulder portion 63 connecting the neck portion 62. A thread 64 for screwing a lid (not shown) is formed on the outer peripheral surface of the neck portion 62, and a convex portion 65 is formed on the lower portion of the outer peripheral surface. Further, on the top surface of the neck portion 62, two spouts for separately pouring out two kinds of contents filled in the inner tube 80 and between the inner tube 80 and the inner tube 60, respectively. 66 and 67 are provided, and check valves 69 and 69 are provided above the inner peripheral surface thereof via hinge portions 68 and 68. Further, on the inner peripheral surface of the neck portion 62, two annular recessed portions 70, 70 for closely fitting an annular protruding portion 87 of a neck portion 85 of a flow dividing piece 84 of the inner tube 80, which will be described later, are formed in the circumferential direction. ing. Further, a positioning rib 71 for the outer tube 50 and the valve body 40 is formed on the lower portion of the outer peripheral surface of the neck portion 62.

As shown in FIG. 7, the valve body 40 is a soft plastic annular seat having two flanges 41, 41, and alignment recesses 42, 42 are formed on the inner peripheral surface thereof. ing. The valve body 40 is positioned by the alignment rib 71 of the inner tube 60, and is set so that the air hole 54 of the outer tube 50 is closed by one of the two flanges of the valve body 40. The material of the valve element 40 is not particularly limited as long as it is a thin sheet.

As shown in FIGS. 8 and 10, the inner tube 80 is broadly divided into an inner sleeve 81 that forms a container for cosmetics and the like, and a space between the inner and inner sleeves 61 and 81 and an inner sleeve 81. It comprises a flow dividing piece 84 having a first passage 82 and a second passage 83 for separately pouring out the two kinds of contents filled therein.

The flow dividing piece 84 further includes a neck portion 85 serving as an engaging portion with the inner tube 60, and a shoulder portion 86 connecting the inner sleeve 81 and the neck portion 85. On the outer peripheral surface of the neck portion 85 of the flow dividing piece 84, an annular convex portion 87 for ensuring engagement with the inner tube 60 is formed. Further, a first passage 82 and a second passage 83 are opened at the top surface of the neck portion 85 of the flow dividing piece 84, and the first passage 82 bends inside the flow dividing piece 84 and the other end side is bent. Has an opening on the outer peripheral surface of the neck portion 85. The second passage 83 linearly hangs inside the flow dividing piece 84 and opens to the lower surface side of the flow dividing piece 84.

It should be noted that the annular convex portion 87 and the annular concave portion 70 may be provided as necessary, and need not necessarily be formed in an annular shape.

Then, the neck portion 85 of the inner tube 80 configured as described above is forcibly fitted into the neck portion 62 of the inner tube 60, and the annular convex portion 87 of the neck portion 85 of the inner tube 80 is inserted into the inner tube 80. The ring recessed portion 70 of the neck portion 62 of 60 is fitted and assembled. That is, the positioning rib 71 of the inner tube 60 is covered with the positioning recess 42 of the valve body 40. Further, the positioning ribs 71 of the inner tube 60 are aligned and fitted into the positioning recessed grooves 55 of the neck portion 52 of the outer tube 50, and the neck portion 52 is inserted with the valve body 40 circumferentially sandwiched. Fit on the neck 62. At this time, the inner diameter of the neck portion of the outer tube 50 and the outer diameter of the lower portion of the neck portion of the middle tube 60 are diametrically fitted, and the convex portion 65 formed on the lower portion of the outer peripheral surface of the neck portion of the inner tube 60 has the neck portion 52 of the outer tube 50. Undercut fitting is performed with the eave-shaped protrusion 56 formed on the upper portion of the inner peripheral surface of the.

Furthermore, the inside of the inner tube 80 and the space between the inner tube 80 and the inner tube 60 are filled with the contents, and the bottom of the inner sleeve 81, the bottom of the inner sleeve 61 and the bottom of the outer sleeve 51 are integrated. When fused together, the tube container as shown in FIG. 11 is completed.

In the tube container as described above, since three types of bottom seals with different sleeve diameters are performed at the same time, a difference in wall thickness partially occurs and the sealing performance deteriorates. For this reason, it is desirable that the sleeves of the inner tube 60 and the inner tube 80 be as thin as possible.

When the outer sleeve 51 of the outer tube 50 of the tube container thus formed is pressed with a finger as shown in FIG. 12, the valve body 40 is pressed by the pressure in the air chamber to cause the air hole 54 of the outer tube 50 to move. Since the pressing force of the outer tube 50 is directly transmitted to the inner sleeve 61 of the inner tube 60 and the inner sleeve 81 of the inner tube 80 via the air chamber, the pressing force is applied to the inner tube 60 and the inner tube 60. The contents contained in the space defined between the inner tube 80 and the inner tube 80 rises to form the first passage 82 formed in the flow dividing piece 84 of the inner tube 80 and the neck portion 61 of the inner tube 60. The contents pushed out to the outside through the formed spout 66 and at the same time stored in the space inside the inner tube 80 are formed in the flow dividing piece 84 of the inner tube 80. It is extruded to the outside through the opened second passage 83 and the spout 67 formed in the neck portion 61 of the inner tube 60. In this way, when the contents are pushed out, the check valve 69 opens outward with the hinge 68 as a fulcrum, so that the contents are pushed out without resistance.

Then, when the outer tube 50 is released from the pressure as shown in FIG. 13 after the content is pushed out, the inner pressure of the middle sleeve 61 of the middle tube 60 and the inner sleeve 81 of the inner tube 80 decreases. The check valve 69 closes the first passage 82 and the second passage 83 formed in the flow dividing piece 84 of the inner tube 80 to prevent air from entering. Therefore, not only the deterioration of the contents due to oxidation can be prevented, but also the contents contained in the space defined between the inner tube 80 and the inner tube 60 and the space inside the inner tube 80 can be accommodated. It is possible to take out an equal amount of contents by applying the same pressure as the contents. However, externally, the inner tube 80 and the inner tube 60 are in a deflated state.

On the other hand, in the outer tube 50, the valve body 40 closing the air hole 54 is displaced downward due to the pressure difference between the inner and outer sides due to the restoration of the outer sleeve 51, and the air hole 54 is opened, so that the outer air is exposed to the outer tube 50. By inhaling into the air chamber between the inner tube 60 and the inner tube 60, the state before pressing is completely restored as shown in FIG. Therefore, even when the check valve 69 for preventing the oxidation of the contents is closed, the appearance is substantially the same as that before the pressing, and the drawbacks of the conventional tube container can be solved.

15 to 17 show a modified embodiment in which the positions of the air holes 54a and 96 provided in the outer tubes 50a and 90 of the tube container of the present invention are changed. In the embodiment of FIG. 15, a thread 92 is formed on the neck portion 91 of the outer tube 90, and the neck portion 62 of the inner tube 60 is sandwiched between the neck portion 85 of the inner tube 80 and the neck portion 91 of the outer tube 90. It is fitted in. Further, the top surface of the neck portion 91 is provided with two spouts 92 and 93 for separately pouring out the two kinds of filled contents, and the hinge portions 94 and 94 are provided above the inner peripheral surface thereof. Check valves 95, 95 are provided. Furthermore, the air hole 96 is provided in the lower portion of the neck portion 91 of the outer tube 90, and the valve body 45 has a state in which the inner peripheral edge thereof is sandwiched between the neck portion 91 of the outer tube 90 and the neck portion 62 of the middle tube 60.

[Effect of device]

 A tube container according to the invention for the distribution of at least one fluid comprises at least one deformable tube containing the product to be distributed, the tube being closed at one end and at the other end. With a nozzle that can push out the contents when the tube is deformed by pressure, the tube is surrounded by an elastically deformable outer tube, and the space between the tube and the outer tube communicates with the atmosphere The space between the tube and the outer tube can be freely communicated with the atmosphere side by, for example, an air inlet / outlet hole. Therefore, when the user applies a compressive force to the outer tube, only the outer tube is deformed, and the air between the outer tube and the outer tube is in contact with the tube, that is, the user is applying to the outer tube. Escape from the hole until the tube is mechanically compressed directly by action. When the user relaxes the force on the tube container, the outer tube elastically recovers its original form, independent of the tube, allowing outside air to escape from the holes in the space between the outer tube and the tube. Inhaled.

Further, the space between the tube and the outer tube is communicated with the atmosphere through the air inflow hole provided with the check valve which allows the communication with the outside only in one direction from the outer side to the inner side, In this case, any compression deformations that the user exerts on the outer tube will increase the pressure of the air between the outer tube and the tube due to the check valve, indirectly compressing the tube, and The contents are poured out. When the user loosens the pressure applied to the outer tube, the elasticity causes the outer tube to return to its original shape without deformation, and the amount of air corresponding to the amount of the contents extruded previously is reversed to the reverse state of the outer tube. It is sucked into the space between the outer tubes via the stop valve.

In particular, the discharge nozzles of the tubes may be equipped with a check valve, which allows the internal space of each tube to communicate with the atmosphere in only one direction from the inside to the outside, the discharge nozzle being provided with a check valve. As such, no air can enter the interior of the tube, and thus there is no contact between the air and the contents within the tube. Furthermore, when a check valve is installed in the air inlet hole of the outer tube, such a check valve is provided in the discharge nozzle of the tube, so that the contents inside the tube can be reliably pushed out by pressing the outer tube. However, depending on the pressure applied to the outer tube, the amount of contents poured can be adjusted.

Further, according to the present invention, in a tube container in which a check valve for shutting off the outside air is provided in a pouring passage communicating between the inside and the outside of a tube filled with contents, the tube container is provided with an air chamber outside the tube. By providing the outer tube, fitting the neck of the outer tube to the neck of the tube, fusing the bottom of the outer tube integrally with the bottom of the tube, and forming an air hole in the outer tube so that it can be opened and closed. When the pressure on the outer tube is released after the contents have been pushed out, outside air can be prevented from entering the tube to prevent the contents from being oxidized.

Further, even if the check valve is closed and the tube is deflated, outside air can enter the air chamber through the air holes, and the outer tube can return to the appearance before being pressed. It has an extremely excellent effect on the tube container.

Further, in a tube container in which a check valve for shutting off the outside air is provided in a pouring passage that communicates the inside and the outside of a tube filled with contents, a concentric tube is formed inside the inner tube forming the body part. The inner tube is placed in the inner tube, and the contents are separately filled between both tubes and inside the inner tube, and the flow dividing piece is integrally formed at the neck of the inner tube. The above check valve is installed on the inside of the tube, the outside tube is provided outside the middle tube through the air chamber, and the neck of the outside tube and the inside tube is fitted to the flow dividing piece of the inside tube. The inner tube and the bottom of the inner tube are fused together, and the outer tube has air holes that can be opened and closed. Then, the check valves are closed due to the decrease in the inner pressure of the inner tube and the inner tube, and the outside air is prevented from entering these tubes, which prevents the contents from being oxidized and the contents of the two chambers It is evenly poured.

Further, even if the check valve is closed and the inner and inner tubes are deflated, outside air can enter the air chamber through the air holes, and the outer tube can return to the appearance before being pressed.
