That is, the liquid container provided by the present invention is a non-expanded first film or sheet (hereinafter referred to as a blister film) in which at least a storage section and a discharge passage section are separated and bulged on one side. A liquid container in which a second film or sheet (hereinafter referred to as a substrate film) is bonded and integrated on the exit side, at least between the storage section and the discharge passage section, and between the two films. In addition, a punched piece of a third film or sheet (hereinafter referred to as an intermediate film) of a different type that reduces the bonding strength between the two is interposed and the two are integrally bonded. That is, the bonding strength of the intermediate film intervening portion is weaker than the bonding strength of the direct joint portion between the blister film and the substrate film. Therefore, when the storage section is compressed, the internal pressure increases and a force is exerted that causes the bonding surfaces of the surrounding films to peel off, but the intervening intermediate film part (hereinafter referred to as the "easy-to-open part"), where the bonding strength is particularly weak, is easily pierced. The housing section and the discharge passage section communicate with each other. As a result, the liquid in the storage section is taken out to the outside through the discharge passage section. The above-mentioned compression can be performed with one hand, and the directionality of liquid discharge is extremely good, so that the above-mentioned problems are solved at once. The method for manufacturing the liquid container is to run a blister film with the non-expanded side facing upward, inject liquid into a storage recess formed in the film, and then When manufacturing a liquid container by overlapping a substrate film on the surface and bonding the two and trimming and cutting it, a small piece of a size to be inserted in the easy-to-open part is punched out before or after the liquid injection process. The gist of the present invention is to run the intermediate film on which the removable part is formed above the blister film, and to punch out and separate the small piece from the intermediate film in such a manner that the removable part is joined to the easily openable part. It is something.

However, in consideration of ease of joining, fastness, reliability, etc., the heat sealing method is preferable. The material suitable for heat sealing is thermoplastic synthetic resin, but especially for the blister film, it is necessary to consider the workability of forming the blister and the ease of compressive deformation when draining the liquid. , those with high flexibility or flexibility are preferred.
Films or sheets that satisfy these conditions include thermoplastic films or sheets made of polyethylene, polypropylene, polyvinyl chloride, polyester, polyamide, polystyrene, ionomers, etc., or composite films made by combining these materials. used. Particularly preferred materials include a composite film of polyethylene and polyvinyl chloride, and a composite film of polyethylene and polyamide. In addition, when using these composite films or sheets, it is recommended to use polyolefin such as polyethylene or polypropylene for the surface in contact with the liquid content, considering chemical resistance and hygiene, and the thickness of the polyolefin layer is is recommended to be 10 to 100 μm, preferably 20 to 80 μm. Each of the above-mentioned films is subjected to blister forming as described above, and since this portion is thinned by drawing, problems may arise in terms of breakage or barrier properties. Therefore, the film as a whole is
A thickness of 100 to 500 μm, preferably 150 to 300 μm is recommended. In addition, if the thickness is too thick, it is not preferable because the workability when draining the liquid by pressing the storage section becomes poor. Next, the substrate film is generally used in its flat form, but in some cases, this film may also be subjected to blister forming.

When performing blister molding, the same thing as the blister film described above can be considered, but since it is not general-purpose,
The following explanation will be made by considering only the use in a flat plate shape. That is, the substrate film may be a thermoplastic film or sheet made of polyethylene, polypropylene, polyvinyl chloride, polyester, etc., or a composite film made by combining these materials with aluminum foil or the like. Particularly preferred materials include a composite film of polyethylene and polyethylene terephthalate, a composite film of polyethylene and aluminum foil, and the like. As for the surface that comes into contact with the liquid content, polyolefins such as polyethylene and polypropylene are preferred, as in the case of the blister film, and if heat-sealing properties are taken into consideration, it is desirable to use the same type of material. The thickness of the above polyolefin layer when blister molding is not performed is 5 to 50μ in the case of a composite film.
It is recommended that m1 is preferably 10 to 30 μm. Next, as the intermediate film, it is recommended to use a film that is different in nature from the film on the surface of each of the above-mentioned films that comes into contact with the liquid content, but in consideration of heat sealing, it is preferable to Those having a softening point as high as the above are preferred, and care must be taken to ensure that the intermediate film is not sufficiently heat-sealed to exhibit easy opening.

Regarding the heat seal strength, compared to each strength of both sides of the intermediate film in the easy-to-open part, the strength of the direct heat seal part between the blister film and the substrate film is
It is preferable to make the strength 3 times or more. If this strength is less than 3 times, it is difficult to ensure that the easy-to-open part can be selectively opened when the storage part is pressed, and in some cases, other sealed parts or The molded part of the blister may break, causing the contained liquid to scatter. DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration and effects of the present invention will be described below based on drawings showing embodiments.

When external pressure is applied to the liquid storage section 2 at this stage, this pressure is evenly transmitted to the heat seal section 4 and the easy-to-open section 5;
Since the bonding strength of the easily openable portion 5 is low, this portion is peeled off as shown at 5' in FIG. 3, and the storage portion 2 and the discharge passage portion 3 are connected. As a result, the resistance of the housing section 2 is eliminated, and the housing section 2 is crushed as shown in FIG. 3, and the liquid 6 is discharged to the outside through the easy-open section 5' and the discharge passage section 3. That is, the liquid can be discharged with one hand, and the direction of the discharge is correctly in the direction of the passage section 3, so that the liquid will not be scattered in an unspecified direction. Another feature of the present invention is the structure of the easy-to-open portion and the method for forming the same, the outline of which is shown in FIG.

That is, as a simple method of forming a blister/package, a blister/film 8 formed to have a storage section 2 and a passage section 3 is arranged as shown in FIG. In other words, the liquid 5 is placed in the storage section 2 with the non-bulging surface side facing upward.
is injected, and after the substrate film 9 is overlapped so as to cover it, the contact plane portion is heat-sealed. However, if the entire surface is heat-sealed with uniform strength, the part 5 cannot be made into a special easy-to-open part. On the other hand, in FIG. 5, the punched small piece 10 of the intermediate film as described above is placed between the storage section 2 and the discharge passage section, and between the blister 1 and the film 8.
and the substrate film 9, the heat-sealing strength of this portion was reduced, resulting in an easily openable portion. By the way, polyvinyl chloride film (2001tm) and polyethylene film (50μm)
) was formed into a blister to form a blister film 8, a 12 μm (7) 0 pp (oriented polypropylene) film (10 m 1 fL square) was interposed as an intermediate film, and a polyethylene terephthalate film (30 μm) was used as a substrate film. Using a composite film of polyethylene film (30μm), 5kg/d-G
Heat sealing was performed for 5 seconds at 65° C. to create an empty container. When the storage part of this container is crushed and the air inside is released via the discharge passage, the crushing pressure is 2
However, when the punched pieces of the intermediate film are not interposed, the crushing pressure is more than 20 kg when the polyethylene film parts are bonded together, and when the punched pieces of the intermediate film are inserted, the crushing pressure is more than 20 kg. It is clear that an easily openable part was obtained. Figures 6 and 7 are examples showing other shapes of the container, including the trimming shape and the storage part 2.

Blister forming may be performed by vacuum forming or pressure forming. Also, compressed air may be blown to clean the recesses after molding. In this way, the film 8 travels with the concave portion facing upward, and the intermediate film 10 is temporarily heat-sealed. The temporary heat sealing process will be described later with reference to FIGS. 11 to 14, but the point is that the film 8
The small piece punchable portion 10A of the intermediate film 10 is temporarily heat-sealed to the upper main portion. After that, the liquid 6 is injected from the tank 14, but the liquid 6 may be injected before the temporary heat sealing, and the point is that after these steps, the substrate film 11 is further introduced so as to cover the top of the liquid 6. . Then, the main heat sealing between the films 8 and 11 is performed by the heat sealing device 15. These heat sealing methods are not intended to limit the present invention, and for example, external heating methods such as a hot plate sealer or impulse sealer, or internal heating methods such as an ultrasonic sealer may be used. In addition, when performing heat sealing, in order to prevent the stored liquid from deteriorating,
An atmosphere of nitrogen gas or carbon dioxide gas may be formed. Finally, the container 1 is cut and separated while adjusting its external shape by a trimming device, and the remaining film 17 is wound up by a scrap winder. Finally, the temporary heat sealing process of the intermediate film will be explained with reference to FIGS. 11 to 14.

The intermediate film 10 is supplied as a strip-shaped film, and a small piece punchable portion 10A having a size corresponding to the shape of the easy-to-open portion is formed in advance (this can be formed immediately before the production line). ). In the figure, a cutting line is formed along the periphery with a portion left, to facilitate detachment as described later, but the punched portion may have another configuration, for example, along the entire periphery. A means for forming a shallow score line, etc. is shown. The intermediate film 10 is fed in the same direction (or may be orthogonal) to the blister film 8, but the small piece punchable portion 10A
It is necessary to attach the mark 19 accurately to the position corresponding to the easy-to-open part, and it is desirable to apply a mark 19 such as printing or perforation so that the mark 19 can be detected by the sensor 18, as shown in the figure.

Although these production lines may run each film continuously, it is desirable to run the films intermittently in terms of reliability, and in particular, it is preferable to run the temporary heat sealing process and the main heat sealing process. At this stage, it is advantageous to temporarily stop the running of the film. The mark 19 is also useful in this respect, and the sensor 18 uses the mark 19.
Each sealing process can be performed by stopping the film travel when the film is detected or after a certain period of time using a timer. Therefore, it is preferable to use geared motors as the feed motors 20, 20'. The temporary heat-sealing section is composed of a presser rod 21 and a separating plate 22, which are moved in opposite directions by air (or hydraulic) cylinders 23 and 24, respectively.

The presser rod 21 is formed with a leg portion 21A so as to be able to press the punched portion 10A as it is, and is heated by a heater 25. Although there are no restrictions on the heating temperature, it is generally desirable that the heating temperature be higher than the softening point of the blister film 8 and lower than the softening point of the intermediate film 10. Further, a through hole (not shown in the drawing) is formed in the separation plate 22 so as to face the leg portion 21A, in other words, to correspond to the small piece punchable portion 10A. Therefore, each of the films 8 and 10 stops, and the legs 21A1, the small piece punchable part 10A1, the through hole of the separation plate 22, and the film 8
When the upper easy-to-open portions are completely aligned, the cylinder 23 is actuated to lower the rod 21 and the leg portion 21A aligns with the punched portion 10.

Then, while punching out this part, it passes through the through hole of the separation plate 22 and is temporarily heat-sealed onto the film 8. Then, the cylinder 23 is actuated to raise the rod 21, and at the same time, the cylinder 24 is actuated to raise the separating plate 22. As a result, the film 10 has a small piece punchable portion 10A.
The separation plate 22 is lifted up while remaining on the surface of the film 8 to complete the temporary heat sealing process, and the separation plate 22 is lowered to its original position. Next, the motors 20, 20' are operated to perform the next setting, and thereafter temporary heat sealing is performed in the same manner. In this way, the liquid injection and main heat sealing steps shown in FIG. 10 are further performed to manufacture the liquid container of the present invention.

Since the structure of the present invention is as described above, the liquid can be discharged from the obtained container with one hand, and the direction of the discharge is accurate, and there is no fear that the liquid will scatter in all directions. In the above explanation, the formation position of the easy-to-open part is limited to between the storage part and the discharge passage part, but in consideration of the hygiene of the discharge passage part, the outlet part is temporarily heat-sealed by the above method. It is also possible to open it only when in use.
