Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is designed to store separately when storing, and to integrally store and hold two liquids that are mixed during use in a state of being closely separated, and to open the space between both liquid storage spaces during use so that they can be mixed in a container. The present invention relates to a two-liquid storage container.

[0002]

[Prior Art]

 There is a two-liquid storage container configured to store and hold two kinds of liquids in a tightly separated state during storage, and to mix and mix at a fixed ratio before use. As this two-liquid storage container, there is a container disclosed in Japanese Utility Model Publication No. 62-38912.

The conventional technique disclosed in Japanese Utility Model Publication No. 62-38912 discloses a container main body having a thread attached to the outer circumference of the mouth, and an engagement cylinder body fitted in the neck of the main body of the container. , The lower cylinder part is screwed onto the outside of the mouth of the container to raise the cylinder part, and the sliding cylinder part is hung from the inner surface of the cylinder part through the engagement cylinder part. Consisting of a lower lid fitted to the lower end of the sliding cylinder and a cap fitted to the upper end of the connecting cylinder. When the connecting cylinder is loosened with respect to the container body, it contacts the lower end of the engaging cylinder and prevents the rise. Thus, the lower lid is configured such that a part of the lower lid is located below the engaging cylinder so that the lower lid can be detached from the sliding cylinder. This two-liquid storage container is vertically suspended from the inside of the connecting cylinder by screwing the connecting cylinder in the slack direction with respect to the container body from the state in which the two kinds of liquids are stored in a state where they are integrally and densely separated. Along with the sliding cylinder part, the lower lid fitted to the lower end of the sliding cylinder part tries to screw up together, but the outer peripheral part of the bottom plate comes into contact with the lower end of the engaging cylinder body and is blocked. The lid cannot be lifted up, so the lower lid is removed from the sliding cylinder and drops below the container body.At the same time, the connecting cylinder and the container body communicate with each other, and the two Liquids are mixed.

In the conventional technology having the above-described configuration and operation, the two kinds of liquids can be integrally stored and held in a state of being closely separated, and the loosening of the connecting cylinder with respect to the container body can be performed. Since two types of liquids can be mixed only by the operation, the mixing operation is extremely easy and safe, and other excellent effects are exhibited.

However, in the conventional technique disclosed in Japanese Utility Model Publication No. 62-38912, a part of the connecting cylinder has a double cylinder wall structure, and this double cylinder wall structure portion is included. Since the internal thread structure is provided in the connection cylinder, the structure of the connecting cylinder is relatively complicated. Therefore, it is necessary to mold the connecting cylinder with a synthetic resin material with good moldability. There is a problem in that it may not be possible to use a synthetic resin material having good moldability depending on the content resistance.

Further, since the container main body for directly containing the liquid and the connecting cylinder are directly screwed together, the molding material for the container main body and the connecting cylinder exhibits stable mechanical strength in addition to high content resistance. Therefore, there is a problem that the physical properties of the container are required, and this also strengthens the regulation of the molding material of the container main body and the connecting cylinder.

Then, the container main body and the engaging cylinder body are assembled by screwing and assembling the container body filled with a certain amount of liquid to the connecting cylinder in which the engaging cylinder body is assembled together with the lower lid. By this screwing and assembling operation of the container main body to the connecting cylinder, the engaging cylinder body, which is assembled to the connecting cylinder in a fixed posture, is engaged and assembled to the opening of the container main body.

As described above, the assembling of the engaging cylinder body to the container main body requires the screwing and assembling operation of the container main body and the connecting cylinder, which are in the state of being filled with the liquid, so that it is suitable for the assembling work. It is necessary to take extra care, and the screwing force between the container main body and the connecting cylinder is used to achieve the engaging assembly of the engaging cylinder to the container main body, so that the container main body and the connecting cylinder are extremely strong. Since it is necessary to assemble them by screwing, the strength with which the container main body and the connecting cylinder are screwed together becomes excessive, making it difficult to achieve the opening operation, and there are inconvenient problems such as illegal deformation of the threads. There is.

Further, in the above-mentioned conventional technique, since the barrel portion of the container main body is located in the lower part, in order to extract the mixed two liquids, the container main body located in the lower part of the entire container is extracted. Since the barrel portion of squeeze must be squeezed, there is a problem that the liquid pouring operation is difficult.

Therefore, the present applicant first constructed the lower volume and the upper volume, which are the main parts that directly store and hold the liquid, so that they are irrelevant to the binding of both volumes and the sealing action between both volumes. As a result, we have proposed a two-component storage container for the purpose of weakening the restrictions on the molded synthetic resin material of both containers and simplifying the assembly operation of the entire container (Practical application No. 1-132609).

[0011]

[Problems to be solved by the device]

 However, in the two-liquid container that was previously filed, the lid that liquid-tightly defines the lower volume and the upper volume fits into the inner cylinder (undercut fitting), so that the lower volume and the upper volume are combined. When mixing the contents stored separately, a large rotational torque is required to remove the lid from the inner cylinder, which is a problem of poor usability.

Further, in order to reduce this torque, it is considered that the fitting force between the lid and the inner cylinder is reduced. However, if the fitting force between the lid and the inner cylinder is reduced, the gas of the lower container and the upper container is reduced. The tightness becomes poor, and the contents that have been separated and stored in the lower volume and the upper volume at the time of use are mixed, and the reliability as a two-liquid storage container decreases. Further, in the case of undercut fitting, there is a problem that the fitting force decreases with time, which also reduces the reliability of the two-component storage container.

The present invention has been made in view of the above points, and an object of the present invention is to provide a two-component storage container capable of removing the lid from the inner cylinder with a small rotating torque and improving reliability. And

[0014]

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, a mouth tube is erected at the upper end of a bottomed cylindrical body tube, and a lower tube in which a first content is stored An upper container having a position container and a discharge port for accommodating the second contents and discharging the first and second contents and having a mouth tube protruding from an opening formed at the lower end. And a neck cylinder piece formed at the lower end of this joint cylinder is liquid-tightly and immovably assembled to the mouth cylinder, thereby providing the above-mentioned lower container. Has a double-cylinder structure including an inner connecting body fixed to the inner cylinder, an inner cylinder, and an outer cylinder arranged outside the inner cylinder. The first screw thread is formed on the upper part of the inner cylinder. A support cylinder that has a fixing mechanism for fixing the outer cylinder to the upper container and that is formed by extending downward from the outer cylinder serves as an internal connector. The external connection body has an external connection body that is rotatably attached so that it cannot be pushed out, and an engagement line that is vertically slidably engaged with the connection line formed on the internal connection body. Has a second screw thread that is screwed with the first screw thread formed on the inner cylinder of the inner cylinder, and closes the mouth tube with the first screw thread and the second screw thread screwed together. It is characterized by comprising a lid and a two-liquid storage container.

[0015]

[Action]

 By configuring the two-liquid storage container as described above, the lid body is attached to the external coupling body by screwing the first screw thread and the second screw thread. Therefore, the binding force between the lid and the external connector is strong, the lid does not loosen from the external connector over time, and the reliability of the two-liquid container can be improved.

When mixing the first contents stored in the lower container and the second contents stored in the upper container, the outer connector is rotated to remove the lid from the outer connector. At this time, since the lid body is attached to the external coupling body by screwing the first screw thread and the second screw thread, the lid body can be removed from the external coupling body with a small rotation torque. Therefore, usability can be improved.

Further, the engagement strip formed on the lid body engages with the connection strip formed on the internal coupling body, whereby the force for rotating the lid body is transmitted to the lid body, and the lid body is smoothly moved. It can be removed.

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of a two-liquid storage container which is an embodiment of the present invention.

The subordinate container 1 is configured by vertically arranging a cylindrical mouth tube 3 with a diameter reduced in three steps at an upper end of a bottomed cylindrical body portion 2, and a cylindrical portion immediately below the mouth tube 3 is necked. A cylinder 4 is provided, and an engagement notch 5 is formed on the outer peripheral surface of the neck cylinder 4 in the form of a circumferential projection that is partially cut away. The first contents 1A are stored in the lower container 1.

The inner connecting body 6 has a smooth surface on the outer peripheral surface through an outer flanged flange 8 at the lower end of the connecting cylinder 7 having a rotation restricting strip 7a extending vertically on the outer peripheral surface. A straight cylinder-shaped neck tube piece 10 is vertically provided. At the lower end of the neck cylinder 10, an engagement piece 12 that engages with and engages with the engagement notch 5 is provided on the inner peripheral surface. Further, a cylindrical sleeve 11 having a notch 13 protruding from the lower end of the outer peripheral surface is formed by being vertically provided via a shoulder portion, and a packing 14 is attached to the lower surface of the flange 8. ing.

The internal connector 6 is forcibly fitted from above the lower container 1 to engage the engaging piece 12 with the engaging recess 5 from the vertical direction and the circumferential direction, so that the inner connector 6 is detached from the lower container 1. It is immovably and non-rotatably assembled, and is tightly elastically attached to the packing 14 on the upper end surface of the mouth tube 3 to be liquid-tightly assembled to the lower container 1.

The outer connecting body 19 has a shape in which an inner flange piece 25 is connected between the lower ends of a double structure of an inner cylinder 20 and an outer cylinder 23, and the outer cylinder 23 is extended downward and supported as it is. The structure is such that the cylinder 26 is formed. The inner cylinder 20 is provided with a thread on its outer peripheral surface that is screwed into a threaded cylinder 17 formed in a lid body 15 to be described later. A hermetic sealing strip 22 is provided so as to be in close contact with the outer peripheral surface of the neck tube piece 10 of the connecting body 6 in a protruding manner. An engagement strip 24 is projectingly provided on the inner peripheral surface of the outer cylinder 23, and a stopper strip 27 is projectingly provided on the lower end edge of the inner peripheral surface of the supporting cylinder 26.

A second content 29 A is stored in the upper container 29, and a nozzle body 34 that forms a spout having a desired diameter is attached to the mouth tube piece 33. The nozzle body 34 is attached to the mouth tube piece 33 so as to be immovably and immovably exteriorly mounted by screwing the assembly tube 35 into the mouth tube piece 33. Further, the nozzle body 34 has a truncated cone shape, and a discharge port 36 for discharging the content is formed at the upper end portion thereof. Further, the cap body 39 can be attached to the nozzle body 34 in order to prevent discharge of the contents when not in use.

The above-mentioned external connector 19 is fixed to the upper container 29. Specifically, an engaging strip 30 is formed at a lower outer peripheral position of the upper container 29, and the engaging strip 24 formed on the outer cylinder 23 of the external coupling body 19 is firmly formed on the engaging strip 30. And the outer coupling body 19 is fixed to the upper container 29. Further, an opening is formed in the bottom surface portion of the upper container 29, and the inner cylinders 20 of the inner connecting body 6 and the outer connecting member 19 project into the upper container 29 through the opening. The inner connecting body 6 and the inner cylinder 20 make the lower container 1 and the upper container 29 communicate with each other.

Next, the lid 15 which is the main part of the present invention will be described.

The lid 15 is attached to the upper part of the connecting cylinder 7 of the inner connecting body 6 and the inner cylinder 20 of the outer connecting body 19, and in a mounted state, the lower container 1 and the upper container 29 are liquid-tightly separated. In addition, the function of connecting the lower volume 1 and the upper volume 29 in the removed state is achieved.

The lid body 15 is composed of a lid portion 15a, and an engagement barrel 16 and a screw barrel 17 which are formed in the lid portion 15a with a double-walled wall structure. The engagement tube 16 is a tube portion disposed inside, and is formed in the inner peripheral portion so that the engagement thread 16a that engages with the connection thread 7a formed on the above-described connection tube 7 extends in the vertical direction. Has been done. Further, the screw cylinder 17 is formed on the outer side of the engagement cylinder 16, and a screw thread that is screwed into the screw thread formed on the inner cylinder 20 is formed on the inner peripheral portion thereof. The screw cylinder 17 may be formed inside the engagement cylinder 16. Further, a foam packing 21 is arranged in the inner part between the engagement cylinder 16 and the screw cylinder 17. FIG. 1 shows a state in which the lid body 15 is attached. In this attached state, the screw cylinder 17 is screwed with the inner cylinder 20, and the tip of the inner cylinder 20 has a foam packing 21. The screw cylinder 17 is in a liquid-tight state between the inner cylinder 20 and the inner cylinder 20. Further, when the lid 15 is attached, the lid 15a is liquid-tightly pressed onto the upper portions of the connecting cylinder 7 and the inner cylinder 20, so that the lower container 1 and the upper container 29 are liquid-tightly defined. The first contents 1A and the second contents 29A are stored in the containers 1 and 29 in a separated state.

Next, a method of using the two-liquid container having the above-described configuration (method of mixing the first contents 1A and the second contents 29A) will be described. The two-liquid container is in the state shown in FIG. 1 before use, and the lid body 15 defines the lower container 1 and the upper container 29 in a liquid-tight manner. From this state, in order to mix the first contents 1A and the second contents 29A, the lower container 1 is rotated with respect to the upper container 29 in the direction indicated by the arrow in FIG.

When the lower container 1 is rotated, the internal connector 6 fixed to the lower container 1 is also rotated accordingly. Further, since the connecting strip 7a formed on the connecting cylinder 7 of the internal connecting body 6 is engaged with the engaging strip 16a formed on the engaging cylinder 16 of the lid 15, the lower container 1 is not rotated. It is transmitted to the lid body 15 via the internal connecting body 6, and the lid body 15 rotates.

On the other hand, the screw cylinder 17 of the lid body 15 is screwed into the inner cylinder 20 formed in the outer connecting body 19, and when the lower container 1 is rotated, the upper container 29 becomes the lower container 1. On the other hand, they are in a mutually stopped state. Therefore, even if the lower container 1 rotates, the inner cylinder 20 does not rotate. Therefore, as the lower container 1 is rotated, the screw engagement between the lid body 15 and the screw cylinder 17 is loosened, and eventually the lid body 15 is separated from the screw cylinder 17 as shown in FIG. As a result, the lower container 1 and the upper container 29 communicate with each other, and the first contents 1A and the second contents 29A are mixed.

As described above, in order to mix the first contents 1A and the second contents 29A, the lower container 1 is rotated and the lid 15 is rotated with respect to the inner cylinder 20. Since the body 15 is attached to the inner cylinder 20 by being screwed, the lid body 15 can be rotated with a small rotation torque as compared with the conventional configuration in which the lid body is fitted and coupled (undercut fitting). Can be removed. As described above, the structure in which the lid body 15 is attached to the outer connecting body 19 by using the screw structure has good adhesion between the lid body 15 and the outer connecting body 19, and the lid body 15 can be removed with time. It will not come loose from the external connector 19. Therefore, the first and second contents 1A and 29A can be reliably stored.

Next, a method of assembling the two-liquid storage container will be described with reference to FIG. To assemble the two-liquid storage container, first, the lid body 15 is screwed into the inner cylinder 19 of the outer coupling body 19, and then fixed to the upper container 29. As a result, the opening formed at the bottom of the upper container 29 is closed by the lid 15, so that the upper container 29 can be handled as one container. Subsequently, the second content 29A is filled through the opening formed in the upper portion of the upper container 29, and when the filling is completed, the nozzle body 34 is attached to the upper container 29 and the cap 39 is attached to the nozzle body 34. Attach to. As a result, the second contents 29A have a structure sealed in the upper container 29. An internal connector 6 is attached to the lower container 1. After the inner connecting body 6 is fitted, the lower container 1 is filled with the first contents 1A.

Subsequently, as shown by the arrow in FIG. 3, the lower container 1 is strongly fitted to the lower portion of the upper container 29, and the ridges 13 formed in the inner connector 6 are formed in the outer connector 19. The stopper strip 27 is fitted. As a result, the lower container 1 and the upper container 29 are integrated and handled as one container. In this way, the two-liquid storage container can be assembled by a simple operation.

[Effect of the device]

 As described above, according to the present invention, the lid body is attached to the external coupling body by screwing the first screw thread and the second screw thread, so that the coupling force between the lid body and the external coupling body is strong, and Since the lid body does not become looser than the external connection body, the reliability of the two-liquid storage container can be improved.

When mixing the first contents stored in the lower container and the second contents stored in the upper container, the outer connecting body is rotated to remove the lid body from the outer connecting body. At this time, since the lid body is attached to the external coupling body by screwing the first screw thread and the second screw thread, the lid body can be removed from the external coupling body with a small rotation torque. Therefore, usability can be improved.
