DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state before the embodiment of the present invention is loaded on an extrusion gun, and FIG. 2 is a cross-sectional view of the vicinity of the extrusion port unit 2. FIG. 3 is an explanatory view of the structure of the pouch 1. FIG. 3A is a front view showing a state in which contents are not accommodated, and FIG.
[0017]
The pouch 1 is a boat-bottomed pouch. As shown in FIG. 3, a deformed hexagonal film 11c is arranged on one end of two substantially rectangular films 11a and 11b, and the entire circumference of the film 11c is filmed. The film 11a or 11b is fused and the films 11a and 11b are fused at the edges on both sides. The fused portion is indicated by M in FIG.
[0018]
In a state in which a liquid such as a sealing material is accommodated and sealed in the pouch 1 having the above-described structure, the film 11c is substantially flat, and an extrusion port base 21 to be described later can be easily attached.
[0019]
The films 11a, 11b, and 11c constituting the pouch are all laminated films having the same structure, and the structure is shown in a schematic sectional view in FIG.
[0020]
In this example, a linear low density polyethylene (L-LDPE) film 31 / polyamide (PA) film 32 / aluminum (Al) foil 33 / polyethylene terephthalate (PET) film 34 are laminated in order from the inner side of the pouch 1. is doing. The L-LDPE film 31 is a sealing layer, the PET film 34 is a buffer material for preventing bending of the base material and the aluminum foil 33, the aluminum foil 33 is a moisture and oxygen barrier layer, and the PA film 32 is an aluminum foil 33. It functions as a cushioning material to prevent bending. Each film is laminated with an adhesive 35.
[0021]
The contents such as the sealing material are stored in a sealed state in the pouch 1 as described above. In this embodiment, the pouch 1 containing the contents in a sealed state is sold with the extrusion port unit 2 including the extrusion port base 21 and the extrusion nozzle 22 shown in FIGS. Or this extrusion unit 2 is sold separately.
[0022]
Each of the extrusion port base 21 and the extrusion port nozzle 22 is a resin injection-molded body, and the extrusion port base 21 has a state in which a flange portion 21b is formed on one end side of the cylindrical portion 21a, and on the surface of the flange portion 21b. An adhesive layer 21c for adhering to the pouch 1 is laminated, and a male screw 21b is engraved on the outer periphery of the cylindrical portion 21a.
[0023]
The extrusion nozzle 22 is the same as that attached to a conventional cartridge containing this type of content, and is a cone-shaped cylinder having an open end on the large diameter as a whole. The tip of the body is closed when not in use, and is released by cutting at a position corresponding to the required extrusion diameter of the contents. Further, on the inner peripheral surface of the base end portion of the extrusion nozzle 22, a female screw 22a that is screwed into the male screw 21a is engraved.
[0024]
In use, after sticking the extrusion base 21 to the substantially central portion of the film 11c on one end side of the pouch 1 with the adhesive layer 21c of the flange portion 21b, the inside of the extrusion base 21 is adhered with a suitable stick or the like. Drill by breaking. In this state, the female screw 22a of the extrusion nozzle 22 is screwed and fixed to the male screw 21d, and is cut and released at an appropriate position of the tip portion of the extrusion nozzle 22.
[0025]
Then, after the commercially available extruder 82 illustrated in FIG. 12 is prepared and the lid 822 is removed, the embodiment of the present invention prepared as described above is inserted into the cylinder 821 and the lid 822 is attached. The extrusion port 2 is exposed from the small opening 822a. This state is shown in FIG. In this state, the trigger 824 is operated to move the piston 823 to the lid body 822 side, so that the pouch 1 is pressed in the sealed cylinder 821. It is extruded to the outside through the hole formed in the nozzle, and flows out from the tip opening of the extrusion nozzle 22 to the outside. Since the pouch 1 is flexible, the pouch 1 is deformed with a heel as the piston 823 moves forward and the contents are pushed out, and finally almost all the contents can be pushed out.
[0026]
After the contents are used up, the pouch 1 has a thickness of about several millimeters in the initial axial direction, and the volume of the open container is a few tenths compared with the case of using a conventional cartridge. Cost can be greatly reduced.
[0027]
The point to be particularly noted in the above embodiment is that films 32 and 34 made of a polyamide resin or a polyethylene terephthalate resin, which are elastic among synthetic resins, are laminated adjacent to the aluminum foil 33. The polyamide film 32 and the polyethylene terephthalate film 34 serve as a cushioning material, and the aluminum foil 33 can be prevented from being sharply broken. As a result, even when the pouch 1 is bent or swung up in use, the aluminum foil 33 is not cracked, and the function of the aluminum foil 33 as a water vapor barrier layer, a gas barrier layer, and an ultraviolet barrier layer is not impaired. The product is not cured or deteriorated.
[0028]
Here, in this invention, the material and structure of the laminated film which comprise the pouch 1 are not limited to what was used in the above embodiment, What can be illustrated below can be used. 5 and 6 are schematic cross-sectional views.
[0029]
FIG. 5 shows an L-LDPE film 31 / PET film 34 / Al foil 33 / PA film 32 laminated in order from the inside of the pouch 1, and FIG. -LDPE film 31 / PA film 32a / Al foil 33 / PA film 32b are laminated. In any of these structures, it is possible to suppress the aluminum foil 33 from being bent sharply by the polyamide films 32 or 32a and 32b or the PET film 34 as a cushion layer, and the same effect as the previous example can be obtained.
[0030]
Moreover, in the above embodiment, although the ship bottom type pouch was used as the pouch 1, this invention is not limited to this, If it is a flexible pouch which can stick an extrusion port to one end side, it will be arbitrary. A pouch of a form can be used. For example, a pouch of a known form such as a standing pouch, a tube type, an envelope type, a back-paste type, a GZ type, or a modified three-way type can be adopted.
[0031]
Further, as a device for pushing out the contents of the container of the present invention, in addition to the above-described hermetic type extruder, as shown in a perspective view in FIG. 8, a semi-cylindrical extrusion cylinder 41 and a piston moving inside thereof 42 and a known extruder provided with a trigger mechanism 43 for moving the piston 42 are provided with an openable / closable lid 44 for closing the open portion of the upper half of the semi-cylindrical extrusion cylinder 41. Even if an extruder having a different structure is employed, the same effect can be obtained. Moreover, the system which moves the piston of each above extruder with a screw may be sufficient.
[0032]
Further, since the main body of the container of the present invention is a flexible pouch, the contents can be extruded by being sandwiched between two rolls instead of the above-described extruder. It is possible to push out the contents by pushing out an instrument or a pouch by hand, and the extrusion instrument or the extrusion method is not limited at all. In particular, when extruded by hand as described above, the aluminum foil layer is often cracked. However, in the present invention, since a polyamide resin film or a polyethylene terephthalate resin film is laminated on the aluminum foil, the crack does not occur.
[0033]
Further, it is effective to add a lid 23 as shown in FIG. 9 to the extrusion port unit 2 in the above embodiment. The lid body 23 is formed with a female screw 23a screwed to the male screw 21d of the extrusion port base 21 on the cup-shaped inner surface with one open end, and a piercing bar 23b with a sharp tip from the inner bottom surface beyond the open end. The protrusion is formed. Therefore, the lid 23 is screwed into the male screw 21d after the extrusion port base 21 is attached to the pouch 1 and the lid 23 is capped, so that the piercing bar 23b breaks the pouch 1 and the pouch 1 is formed inside the extrusion port base 21. Perforations can be applied. And when this cover 23 preserve | saves in the state in which the content remained, it has a function as a lid | cover which prevents deterioration of a content by attaching to the extrusion base 21 after removing the extrusion nozzle 22. FIG. .
[0034]
Here, in the above embodiment, as an extrusion port for extruding the contents in the pouch, an extrusion port substrate 21 adhered to the pouch 1 and an extrusion screwed to the extrusion port substrate 21 Although the nozzle 22 is used, these are integrated, and as shown in a sectional view in FIG. 10, a flange portion 52 for attaching to the pouch 1 is provided on the proximal end side of the cone-shaped nozzle portion 51. It is also possible to use an integral extrusion nozzle 5 that is integrally formed and laminated with an adhesive layer 53 of the flange portion 52. In this case, after sticking the extrusion nozzle 5 to the pouch 1, in order to perforate the inside thereof, a long instrument such as a driver may be used after cutting the tip of the nozzle portion 51.
[0035]
【The invention's effect】
As described above, according to the present invention, the main body portion of a container for storing a viscous liquid such as a sealing agent is configured by a pouch formed of a flexible film in a bag shape and stored in a sealed state. Sticks an extrusion port to one end of the pouch, punches the pouch inside, and uses the flexibility of the pouch from a nozzle provided at the extrusion port using an extrusion device such as a conventional extruder. Since the contents can be pushed out by the required amount, the manufacturing cost can be greatly reduced compared to the conventional rigid cartridges that contain sealing materials. It can be greatly reduced.
[0036]
In addition, a laminate film is used as the film material constituting the pouch, and this laminate film is laminated with an aluminum foil layer adjacent to a polyamide resin layer or a polyethylene terephthalate resin layer. However, the aluminum foil is not sharply bent due to the presence of the polyamide resin layer or the polyethylene terephthalate resin layer as a cushion layer. Therefore, the function of the aluminum foil as the water vapor barrier layer, the gas barrier layer and the ultraviolet barrier layer is not impaired, and the contents are not cured or deteriorated.
