Problems solved by technology

If the water as storage is poured out from such an opening 218, there will be the following problems: the outflow direction of the water will change due to the shape of the opening 218, and it will be difficult to pour water into the cup, etc., and the operation will be difficult.
Therefore, there are the following problems in use: for example, it takes a lot of time to shape the opening 218, and when the water flow is poured in a close-fit state, the outflow of water is hindered, and it is difficult to control the outflow direction.
[0007] In addition, there is also a concern that when such a clip 220 is used to seal the opening 218, the opening area or opening width of the opening 218 changes due to arbitrary tearing force, and the opening 218 cannot be sealed using the clip 220 prepared in advance.

no. 1 Embodiment approach

[0047] figure 1 and figure 2 Showing the first embodiment of the flexible container of the present invention, figure 1 Indicates the flexible container after enclosing water, figure 2 Indicates a flexible container before being filled with water. The flexible container has an accommodating portion 2 for storing water, liquid, etc. as a content, and is formed of a sheet-like flexible material 3 such as a synthetic resin film. In the present embodiment, as a mechanism for sealing the housing portion 2 in the longitudinal direction, a central sealing portion 4 is formed, and in a direction perpendicular to the central sealing portion 4, an upper side and a lower side for sealing the housing portion 2 are formed. The top sealing part 6 and the bottom sealing part 8. That is, the housing part 2 forms a sealed space sealed by the three sealing parts 4, 6, and 8, and in the present embodiment, the water 10 is housed therein. figure 2 It shows the storage part 2 when the bot...

no. 2 Embodiment approach

[0072] In addition, in the first embodiment, although the unsealing guide 16 is formed bilaterally symmetrically, when the material constituting the unsealing guide 16 is thicker than the flexible material 3 constituting the housing portion 2, for example, as Figure 10 As in the second embodiment shown, the protrusions 30 and 42 of one side of the unsealing guide 16 are formed asymmetrically so as to avoid thermocompression bonding on the top sealing part 6, and the thermal compression of the top sealing part 6 can be reduced. take on the burden. That is, in this unsealing guide 16, the height of the protruding portion 30 is lower than that of the protruding portion 32, the height of the protruding portion 42 is lower than that of the protruding portion 44, and the inclination angle of the inclined edge portion 34 is gentler than that of the inclined edge portion 36. The inclination angle of the inclined edge portion 45 is also gentler than that of the inclined edge portion 4...

no. 3 Embodiment approach

[0075] In addition, when the material constituting the unsealing guide 16 is thinner than the flexible material 3 constituting the housing portion 2, for example, as Figure 11 As in the third embodiment shown, the inclined edge portions 45, 46 are formed as horizontal edge portions 77, and the protruding portions 42, 44 are formed across the horizontal edge portion 77, and these protruding portions 42, 44 may be sandwiched between in the top seal 6. Furthermore, similarly to the first embodiment, even this structure can obtain a uniform opening by the unsealing guide 16 .

Abstract

A flexible container capable of being easily unsealed by tearing up and standardizing an opening shape provided by unsealing, a method of forming the container, an unsealing guide of the container, a method of filling liquid into the container, and liquid, the container comprising seal parts (center seal part (4), a top seal part (6), a bottom seal part (8)) for sealing a storage part (2) formed of a flexible material (3), slits (12, 14) formed in the seal parts, and the unsealing guide (16) installed in the storage part and guiding the direction of unsealing by the tearing-up of the storage part unsealed by the tearing-up thereof from the slits, whereby the unsealing can be facilitated and the opening shape provided by the unsealing can be standardized.

Description

technical field [0001] The present invention relates to containers and the like used for the transportation, storage, and commercialization of liquids, etc., and particularly relates to a flexible container formed of a flexible material such as a synthetic resin film that can be torn and unsealed, a method for forming the same, and an auxiliary container for unsealing. Unsealing guides for flexible containers of parts, methods of sealing liquids in flexible containers for transportation, storage, or commercialization, and liquids enclosed in flexible containers. Background technique [0002] In the past, in the commercialization of drinking water such as mineral water and other liquids, as well as in the process of transportation and storage, a synthetic resin container called a PET (polyethylene terephthalate) bottle was often used. This synthetic resin container is light in weight and high in safety, but it is bulky and difficult to handle because it has high rigidity and ...
