DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible container made of a synthetic resin, and more particularly to a flexible container in which the amount of discharged contents can be easily adjusted and the stored contents hardly remain after use.

[0002]

2. Description of the Related Art Heretofore, as a container for accommodating containers such as liquids, gels, creams, and kneaded materials having a relatively high viscosity, a flexible synthetic resin which can be easily deformed by pressing a container wall. Many are known to be formed from. In order to use such a container, the container is discharged by opening a discharge hole at the end of the container and pressing the container wall from the outer surface side to reduce the volume of the storage chamber. Then, when the remaining amount of the stored material in the storage chamber becomes small, the stored content in the storage chamber is moved to the discharge hole and discharged by pressing and handling the container wall. However, in such a container, it is not easy to adjust the discharge amount from a large amount to a small amount because the discharge amount of the container is adjusted only by adjusting the force when pressing the container wall. It is difficult to discharge the stored contents little by little or continuously in a fixed amount. In addition, when the remaining amount of the contents in the accommodation room is reduced and the container walls are handled and discharged, the container inner wall surfaces can be brought into contact only with the pressing area, so that the contents remaining dispersed in the entire accommodation room remain. It takes time and effort to move the container sufficiently to the discharge hole, and the operation is particularly difficult for a container having a large pressing area, and there is a problem that a large amount of the container remains in the container after use. there were. Furthermore, when the container end portion with the formed discharge hole has a strength that does not deform when pressed, a dead space where the inner wall surfaces of the container walls cannot contact each other near the discharge hole is formed. Even if the contents were moved, they could not be discharged, and the contents were likely to remain after use.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is easy to control the amount of discharge and to discharge easily, and it is a flexible material in which stored items are less likely to remain after use. It is intended to provide a sex container.

[0004]

SUMMARY OF THE INVENTION The present invention, which achieves the above object, provides a container in which a storage chamber is formed by sealing the periphery thereof, wherein the container wall is made of a synthetic resin having flexibility, and the outer surface of the container wall is provided. A bent portion which can be bent so as to face each other is provided in the middle portion of the container, and a discharge hole of the storage chamber is provided in or near the bent portion.

According to the present invention, since the bent portion is provided at the intermediate portion of the container and the discharge hole is provided at or near the bent portion, the container is bent at the bent portion to contact the container walls of the storage chamber. In this state, if the flexible container is pressed from the outermost side in this state, it is possible to press the container walls arranged on the outer side and to press the inner opposing container walls with each other. It is possible to press the storage chambers on both sides of the bent portion to discharge the stored material from the discharge holes. At this time, since the discharge hole is provided at or near the bent portion, the discharge hole can be arranged at or near the end of the bent container. Does not become difficult to discharge. Then, at the time of discharging, by simultaneously pressing the storage chambers on both sides of the bent portion, the storage chamber can be largely deformed, and if only one storage chamber is pressed, the storage chamber can be deformed small. Therefore, adjustment of the discharge amount is easy. Moreover, since the container wall is made of a synthetic resin having flexibility, when the container is pressed at the time of discharging, the container can be easily deformed according to the shape of the pressed portion, and if the pressing area of the container is adjusted, Easy to adjust emissions. In addition, since the discharge hole is provided in the bent portion or in the vicinity of the container, that is, in the intermediate portion of the container, there is no portion that is far from the discharge hole in the storage chamber as compared with the container having the discharge hole at the container end. When discharging the stored material near the end, the amount of movement of the stored material can be reduced, and the discharged material can be easily discharged. For this reason, when the container is handled and discharged, the remaining amount is reduced, so that the container is easily discharged, and the amount of the stored material remaining in the storage room after use can be reduced. In addition, since the container wall is made of a flexible synthetic resin, the container wall can be easily pressed sufficiently even if the remaining amount of the container is small, and the container can be easily discharged to the end.

In the present invention, if the bent portion is formed in a direction crossing the longitudinal direction of the container, the container can be easily held compactly by bending and holding the container, and the container can be formed to be long. It becomes possible. If the container is long, the area of the container wall for the container can be increased compared to the case where the same amount of container is stored in a thick container, and the container deformation area is longer when pressing and discharging the container can do. Therefore, it is easier to adjust the discharge area by adjusting the pressing area of the container. Further, when the discharge hole has a space inside and is provided in the flexible protrusion, the container wall is deformed by bending the container, and the container wall is deformed in the vicinity of the bent portion and the container in the vicinity of the bent portion. Even if the inner surfaces of the walls are in close contact with each other, the communication between the discharge hole and the accommodation chambers on both sides of the bent portion can be reliably maintained by the space inside the protrusion. Therefore, it is easy to discharge the contents from the discharge holes even in the bent state. Further, when the flexible container has a plurality of storage chambers partitioned by the easily peelable partition, a plurality of components that need to be separated and stored until use can be stored and stored in the same container. . In this case, if the easily peelable partition is arranged at the bent portion or in the vicinity thereof, if the bent portion is folded at the time of storage, the container wall of the bent portion is brought into close contact with each other by deformation of the container wall of the bent portion. It is easy to maintain in a state, and it is possible to prevent separation of the easily peelable partition portion during storage and prevent mixing of the stored objects stored in the plurality of storage chambers. In addition, when the discharge hole is arranged between the plurality of storage chambers partitioned by the easily peelable partition, the easily peelable partition is peeled, thereby simultaneously connecting the plurality of storage chambers and discharging. Since the holes can be opened, the usability is good. further,
When a discharge port forming member having a discharge path corresponding to the discharge hole is fixed to the container wall around the discharge hole, the contents discharged from the discharge hole are guided by the discharge port forming member to specify the discharge position. Not only is it easy to perform, but also because the discharge hole is formed in the middle part of the container, the fixing position of the discharge hole forming part is a flat part in the middle of the container, and the discharge port is formed on the flat container wall during manufacturing. The member can be fixed. Therefore, as compared with the case of fixing to the end portion of the container, the discharge port forming member can be easily fixed and securely fixed to prevent liquid leakage from around the discharge hole forming section.

In the holder for accommodating the flexible container of the present invention, the container wall is made of a synthetic resin having flexibility, the periphery thereof is sealed to form an accommodation chamber, and the outer surfaces of the container wall face each other. A holder that accommodates a flexible container provided with a bent portion that can be bent by being provided at the intermediate portion of the container and provided with the discharge hole of the storage chamber at or near the bent portion. A support provided with a fixing portion for fixing a position of the container wall disposed on both sides of the bent portion in a state of being bent and separated from the bent portion, and a container wall of a container chamber of the container fixed to the support. And a pressing member for pressing. According to the holder accommodating the flexible container, the flexible container is bent, and the position separated from the bent portion of the container wall on both sides of the bent portion is fixed to the fixing portion of the support. The relative position between the accommodation chambers arranged on both sides of the bent portion can be specified and fixed to the support.

The discharge port forming part 16 is welded to the top part 15a. The discharge hole forming section 16 has a discharge path 17 corresponding to the discharge hole 13, and a discharge port 18 is formed at a tip portion. Further, a detachable cap 19 capable of sealing the outlet 18 is attached to the outlet forming section 16. Further, in the middle part of the container, a partitioning part 21 which can be peeled off is formed so as to cross the container in a direction intersecting with the longitudinal direction, and the accommodation room 12 between the container and the end seal part 11 is divided into two compartments 2.
It is divided into 2, 22. This partition part 21 has the protrusion 15
Is formed so that the discharge hole 13 is disposed between the compartments 22 and 22 while surrounding the periphery of the container. Each compartment 22 contains two types of viscous components to be mixed before use. The flexible container 10 is bent around a container middle part, in this embodiment, a partition 21, and
The outer surfaces of the container walls of the portions 2 and 22 are in contact with each other while facing each other. Here, the container wall of the flexible container 10 is
And a portion in the vicinity thereof, and the deformed portion is a bent portion 23. Here, the container middle part is
Any portion other than both ends of the container may be used, but preferably, in the container wall having the maximum area of the container, a position which is at least 1/4 of the length in the direction from both ends in the longitudinal direction of the container is suitable. A position separated by 以上 or more is more preferable, and a center part is particularly preferable.

The resin material constituting the container wall of the container 10 is as follows:
It is preferably made of a synthetic resin having flexibility and having such a strength that it can be deformed by a pressing force at the time of discharging. Although not particularly limited, for example, polyolefin resin, polyester resin, polyacrylonitrile resin,
Polyacrylic resin, polyamide resin, vinyl chloride,
Vinylidene chloride resin, polyvinyl alcohol resin,
A flexible resin such as an ethylene-vinyl acetate copolymer, an ethylene-acrylic copolymer, or an ionomer may be used, and these resins can be used as a single layer or a laminate. In order to form the releasable partition 21, it is preferable that the resin serving as the innermost layer has a proper compatibility and is made of a mixture of resins having different melting points. When it is welded at a temperature higher than both melting points, it can be welded irremovably. As such a mixed resin, for example, a mixed resin of polyethylene and polypropylene such as linear low-density polyethylene can be used. In addition, a tubular body made of such a synthetic resin is generally made of a resin container, such as by inflation molding, welding a tube, a film, or a sheet obtained by extrusion molding, injection molding, or blow molding. It may be formed by appropriately using a manufacturing means.

[0010] In such a flexible container 10, the object to be accommodated is not particularly limited. For example, drugs such as ointments, foods such as sauces, ketchup, miso, dressings, drinks, hair dyes, etc. It can contain ingredients in any field, such as cosmetics, glues, daily necessities such as adhesives, and the like. When the storage chamber 12 is not partitioned, the single component is normally stored.

Next, the compartments 22, 22 are formed by forming the partition 21 by surrounding the projecting portion 15 and releasably welding the inner surfaces of the container walls so as to cross the container. Then, different viscous components are filled from both ends of the container, and the ends are welded so that the ends cannot be peeled off.
By forming 11, the flexible container 10 can be manufactured. When the flexible container 10 is manufactured in this manner, the discharge port forming member 15 having the discharge path 17 corresponding to the discharge hole 18 is fixed to the container wall around the discharge hole 18. Becomes a planar part in the middle of the container, and the discharge port forming member 15 is fixed to the planar container wall. For this reason, the discharge port forming member 18 is fixed in comparison with a conventional container in which the discharge port forming member is sandwiched between sheets constituting the container wall and welded in a liquid-tight manner to fix the discharge port forming member to the end of the container. It is easy and secure to fix, and it is easy to prevent liquid leakage from around the discharge hole forming portion.

The flexible container 10 manufactured as described above
First, the partition walls 21 are peeled off by pressing the container walls of the compartments 22, 22 to separate the compartments 22, 2.
2 and the containers in the storage chamber 12 are mixed by repeatedly and alternately pressing the containers. Next, the flexible container 10 is bent at the bending portion 23, and the container walls are brought into contact with each other so as to be in a state shown in FIG. In this state, the body of the storage chamber 12 on both sides of the bent portion 23 is held, and the container is used by pressing the container wall to squeeze the contents of the storage chamber 12.

According to such a flexible container 10 of the present embodiment, the bent portion 23 is provided at the intermediate portion of the container, and the discharge hole 13 is provided at or near the bent portion 23. Is bent to press the flexible container 10 from the outermost side, it is possible to press the container walls disposed on both outer sides and to press the inner opposed container wall surfaces with each other. Part 2
It is possible to discharge the contents from the discharge holes by pressurizing the storage chambers 12 on both sides of 3. At this time, since the discharge hole 13 is provided at or near the bent portion 23, the discharge hole 13 can be arranged at the end or near the end by bending, and even if the discharge hole is provided at the intermediate portion of the container. There is no difficulty in discharging the contents. At the time of discharge, the housing chambers 12 on both sides of the bent portion 18 are simultaneously pressed, so that the housing chamber 12 can be greatly deformed. If only the housing chamber 12 on one side is pressed, the housing chamber 12 is deformed small. The discharge amount can be easily adjusted by appropriately selecting the amount. In addition, since the container wall is made of a flexible synthetic resin, when the container 10 is pressed at the time of discharging, the container 1 is shaped according to the shape of the pressed portion.
0 can be easily deformed, and the discharge amount can be further adjusted by adjusting the area pressed by the container 10. In addition, when the amount of discharge from the storage room on one side of the bent portion is large and the difference occurs in the storage amount between the storage rooms on both sides,
What is necessary is just to unfold the bent part 18 once, equalize the amount of contents on both sides, and use it again. In addition, since the discharge hole 18 is provided in the middle portion of the container, the discharge hole 18 is provided at the end of the container.
As compared with a container provided with a container, there is no longer a portion far from the discharge hole 18 in the storage chamber 12, and the amount of movement of the stored material when discharging the stored material near the end can be reduced, and the discharged material is easily discharged. . For this reason, the remaining amount becomes small, so that it is easy to discharge even when squeezed out, and the amount of stored material remaining in the storage chamber 12 after use can be reduced. In addition, since the container wall is made of a flexible synthetic resin, the container wall can be easily pressed sufficiently even if the remaining amount of the container is small, and the container can be easily discharged to the end.

In the container 10 of this embodiment, the bent portion 23 is formed in a direction intersecting the longitudinal direction of the container 10, and if the container 10 is bent and held, it is easy to hold the container 10 compactly. It is formed long. Therefore, as compared with the case where the same amount of stored items is stored in a thick container, the area of the container wall with respect to the stored items is larger, and the deformed portion of the container 10 when pressing and discharging the container is longer.
Therefore, it is easier to adjust the discharge area by adjusting the pressing area of the container 10. In addition, since the discharge hole 13 is provided in the flexible protrusion 15 having the space 14 therein, when the container is bent and the container wall is deformed in the bent portion 23 and the vicinity thereof, the protrusion is formed. Part or all of 15 is deformed in accordance with the bent shape, and the internal space 14 absorbs the deformation to maintain the space 14 between the discharge hole 13 and the inner wall surface of the container facing the hole 13, The hole 13 and the accommodation chambers 12 on both sides of the bent portion 23 can be maintained in a state of being reliably communicated. Therefore, even if the container 10 is bent and the inner walls of the container 23 adhere to each other at the bent portion 23 and the vicinity thereof, it is easy to discharge the contents in the storage chamber 12 formed on both sides of the bent portion 23 from the discharge holes 23. . Furthermore, since the flexible container 10 is partitioned by the partition 21 having easy peelability,
A plurality of contents can be separated and stored until the time of use. However, since the partition part 21 is arranged at or near the bent part 23, if the storage part is bent at the bent part 23 during storage, the container Due to the deformation of the walls, it is easy to maintain the opposing inner walls of the container in close contact with each other, so that the easily peelable partition portion 21 does not peel off during storage, and it is possible to prevent the contents from being mixed. Further, a plurality of compartments 22 in which the discharge holes 21 are partitioned by the easily peelable partitioning portions 21,
Since the partition 21 is disposed between the plurality of compartments 22, the discharge hole 13 can be opened at the same time that the plurality of compartments 22 are communicated with each other by peeling the partition 21, which is convenient.
