Description

[Detailed description of the invention] ≪Industrial application field≫ This invention is a system in which fluid contents are poured out from a nozzle by squeezing the body of a flexible container such as a tube container. This invention relates to improvements in squeeze-type dispensing containers.

<<Prior Art>> Tube containers are widely used as containers for dentifrice, medicines, cosmetics, and the like. The tube container is
Pour out the contents by squeezing the body of the tube with your hands.

<<Problem that the invention seeks to solve>> With tube containers, it is extremely difficult to squeeze out the contents completely without leaving any residue. When the contents become low, the contents move from the part you squeezed with your fingers to other parts of the container, and tedious operations such as winding up the tube are required to squeeze out everything. Also, especially when the contents are running low, trying to squeeze out the contents without wasting anything may result in pouring out more than necessary at one time. As described above, since the tube container itself is soft, it is not easy to control the pouring amount.

This idea was created in view of the conventional problems mentioned above, and it is possible to squeeze the container uniformly with a simple operation, and in the end, the contents can be squeezed out without leaving any residue, and the amount of pouring can be controlled. It may also provide an easy-to-squeeze pouring container.

≪Means for solving the problem≫ The squeeze-type dispensing container according to this invention includes a flexible container whose body is squeezed in order to pour out the contents from a nozzle, and a flexible container that A highly rigid exterior case that houses the nozzle with it exposed to the outside,
It is provided in the exterior case, has a V-shape whose upper part is bifurcated via a folded part at the lower end, and into which the body of the flexible container is inserted for squeezing, and the folded part is bifurcated into two parts. a pressing plate formed with elasticity capable of closing the upper forked portion; and a pair of pressing plates provided in the exterior case so as to face the upper forked portion of the pressing plate from both sides and facing each other, One end thereof is exposed outwardly from the operating hole formed in the outer case to form a push button part, and the other end thereof is configured to deform the pressing plate in the closing direction by pushing the push button part. , and an operation member forming a V-shaped cam portion that is inserted into and engaged with the upper forked portion.

<<Function>> The push buttons of a pair of operating members are exposed in the operating hole of the outer case, which are arranged so as to face each other and face the upper forked portion of the pressing plate from both sides. When you push the pair of push buttons inward with your fingers, the V-shaped cams of each operating member will press into the upper forked portion of the V-shaped squeeze plate that sandwiches the flexible container inside. As a result, the pressing plate is deformed in the closing direction around the elastic folded portion.
As a result, the flexible container is squeezed by the squeeze plate, and the contents of the flexible container are poured out from the nozzle.

<<Example>> Figs. 1 to 6 show a squeeze type pouring container according to an embodiment of this invention. In the figure, 10 is a tube container (flexible container), 12 is an outer case,
14 is a pressing plate, and 16 is an operating member.

The tube container 10 is made of plastic, has a flexible body, and has a narrow spout hole 10a at the top.
A nozzle 10b is integrally formed. By squeezing the body of the tube container 10, fluid contents are poured out from the nozzle pouring hole 10a. Note that a threaded portion is formed on the outer periphery of the nozzle 10b, and a cap (not shown) is attached thereto to close the spouting hole 10a.

The outer case 12 is a highly rigid case molded from hard plastic, and has a substantially rectangular parallelepiped shape with rounded corners and an inner dimension considerably larger than that of the tube container 10.
A tube container 10, a pressing plate 14, and two operating members 16 are housed inside this exterior case 12.

A circular window hole 12a is opened in the upper surface of the outer case 12, and a nozzle 10b of the tube container 10 contained therein projects upward from the window hole 12a. Furthermore, square operating holes 12b are opened on both sides of the exterior case 12, respectively.
A push button portion 16a of the operating member 16 projects outward from the operating portion hole 12b.

The pressing plate 14 has a V-shape whose upper part is bifurcated via a folded part at the lower end and into which the body of the tube container 10 is inserted in order to squeeze it. In this embodiment, two plates are elastically connected in a V-shape, and the folded part (hinge The two plates are elastically deformed in the opening/closing direction due to the elasticity of the parts. Inside the exterior case 12, the hinge portion of the pressing plate 14 is located at the bottom of the case, and the two plates are arranged so as to sandwich the body of the tube container 10 from both sides.

The operating member 16 is attached to the compression plate 1 in the outer case 12.
A pair of push button portions 16a are provided at the upper forked portion of the housing 4 facing from both sides and facing each other, one end of which is exposed to the outside from an operation hole 12b formed in the outer case 12 and forms a push button portion 16a. The other ends thereof form a V-shaped cam portion 16b which is inserted and engaged with the upper forked portion in order to deform the pressing plate 14 in the closing direction by the pushing displacement of the push button portion 16a. The push button part 16a and the V-shaped cam part 16b in the inner part of the case are integrally formed. The two operating members 16 are located symmetrically in the upper part of the exterior case 12, and the V-shaped cam portions 16b are in contact with the edge portions of the two plates of the pressing plate 14.

3 and 4 show the push button portion 16a of the operating member 16.
In this case, in a free state with no operating force applied to
The compression plate 14 is opened to the maximum extent due to the elasticity of its hinge portion, and the tube container 10 is inflated due to its elasticity.

5 and 6 show the push button portion 16a of the operating member 16.
is pressed in with your fingers as shown by the arrow. 2
When the two operating members 16 are pushed into the case, the edge of the pressing plate 14 that is in contact with the V-shaped cam portion 16b is moved toward the center of the case in accordance with the inclination of the cam portion 16b. That is,
The V-shaped cam portion 16b of the operating member 16 is
4, and the operating member 16 configured in this manner is inserted into the upper forked portion of the pressing plate 1.
4, so that the two plates of the pressing plate 14 are equally displaced in the closing direction centering on the hinge part at the lower bottom by the pushing displacement of these two operating members 16. can be done. Therefore, the tube container 10 sandwiched between the two plates of the pressing plate 14 is compressed uniformly as a whole by the pressing plate 14. Therefore, the contents of the tube container 10 exit through the spout hole 10a.

As is clear from FIGS. 5 and 6, when the push button part 16a is pushed inward, the pressing plate 1
The two plates 4 become almost parallel and completely crush the tube container 10. Therefore, in this state,
Almost all of the contents of the tube container 10 are poured out.

By the way, in this embodiment, the tube container 1
It has a V-shape in which the body of the tube container 10 is inserted in order to squeeze it when the contents are poured out by squeezing the container 10, and the folded part has elasticity to close the upper forked part. The formed pressing plate 14,
A pair of push button portions 16 are provided facing each other at the upper forked portion of the pressing plate 14 from both sides.
The operating member 1 has a V-shaped cam portion 16b that is inserted into and engaged with the upper forked portion in order to deform the pressing plate 14 in the closing direction by the pushing displacement a.
6, simply a pair of operation members 16
By simply pressing the push button part 16a, the pressing plate 14 can be uniformly deformed in the closing direction centering on the hinge part at the lower bottom with these operating members 16, and the entire tube container 10 can be compressed uniformly. can. As a result, unlike the operation of partially squeezing the tube container with your fingers, it is possible to stably pour out the necessary amount of contents with an easy-to-control operation of adjusting the amount of depression of the push button part 16a as appropriate. It is possible to avoid waste due to over-dispensing.

In addition, the pair of operating members 16 are formed by a folded portion having elasticity capable of closing the upper forked portion of the pressing plate 14.
The squeeze plate 14 can be completely closed around the folded part by inserting the tube container 1.
0 can be completely crushed and the contents can be poured out almost completely without any residue.

Further, the pressing plate 14 is bifurcated at the upper part via a folded part at the lower end, and a tube container 1 is placed inside the pressing plate 14.
It is V-shaped to squeeze the body of 0,
In addition, since the folded portion is integrally formed with elasticity capable of closing the upper forked portion, the structure is simple.

Furthermore, since the outer case 12 is highly rigid, it is very easy to apply complex and luxurious decorations to its surface by printing, stamping, etc.

Note that FIG. 7 shows a modification of the exterior case 12. In this example, the top plate 18 of the outer case 12 can be freely opened and closed with respect to the case body, and the tube container 10 inside can be freely attached and detached. That is, the top plate 18 is attached to the main body of the exterior case 12 by the hinge part 20 so as to be openable and closable, and can be fixed in the closed state by the concave-convex fitting part 22.

<<Effect of the invention>> As explained in detail above, the squeeze-type dispensing container according to the invention is a flexible container whose body is squeezed in order to pour out the contents from the nozzle. Inside the highly rigid exterior case, which is exposed to the outside, the upper part is bifurcated through a folded part at the lower end, and the V-shaped body of the flexible container is sandwiched inside for squeezing. A pressing plate is provided in the outer case, and one end of the pressing plate is formed so as to have elasticity that allows the folded portion to close the upper forked portion, and one end of the pressing plate extends outward from the operating hole formed in the outer case. The other end is exposed and forms a push button part, and the other end is a V-shaped part that is inserted and engaged with the upper forked part in order to deform the pressing plate in the closing direction by the pushing displacement of the push button part. Since the pair of operating members forming the cam portion are provided facing each other from both sides at the upper forked portion of the pressing plate, these can be operated by simply pushing the push buttons of the pair of operating members. The pressing plate can be evenly deformed in the closing direction around the folded portion at the lower end using the operating member, and the entire flexible container can be compressed uniformly. As a result, unlike the operation of squeezing the tube container with your fingers, it is possible to stably pour out the necessary amount of contents with an easy-to-control operation of adjusting the amount of push on the push button as appropriate. Waste is less likely to occur.

In addition, since the folded part has elasticity that can close the upper forked part of the pressing plate, the pressing plate can be completely closed around the folded part by inserting the pair of operating members, thereby completely closing the flexible container. It can be crushed and the contents can be poured out almost completely without any residue.

Further, the pressing plate has a V-shape in which the upper part is bifurcated through a folded part at the lower end, and the body of the flexible container is inserted into the V-shaped part in order to squeeze the body part of the flexible container, and the folded part is split into two parts in the upper part. The structure is simple because it is integrally formed with elasticity that allows the parts to be closed.

Furthermore, since the outer case is highly rigid, it is very easy to apply complex and luxurious decorations to its surface by printing, stamping, etc.
