Description of the Related Art Conventionally, in a liquid container, an opening serving as a drinking port is previously provided in a packaging material of the container using paper or a resin material as a main material. Some have a drinking part structure in which a portion to be formed is covered from the outside of the container with a tab tape. FIG. 5 shows an example. The drinking section 1 is provided on the top surface of a liquid container having a shape such as a column, a cone, a prism, and a pyramid. The illustrated drinking section 1 is of a type in which a tab tape is peeled off to break through a film stretched over the drinking port with a straw or the like. A through hole 3 is opened, and an outer protective layer 4 is provided by laminating a laminated film formed by laminating a required resin material on one side 2a of the substrate 2 on the outer side of the container. Penetrating). And
An inner protective layer 5 is provided by laminating a laminated film formed by laminating a required resin material on one side 2b on the inner side of the container, and the inner protective layer 5 seals the through hole 3. Further, a tab tape 6 is peelably attached to the outer protective layer 4 and the inner protective layer 5 exposed in the through hole 3.

The drinking part 1 is formed by laminating a laminated film formed by laminating a required resin material on one side 2 a of the substrate 2 having the through hole 3 opened on the outer side of the container 2. And an inner protective layer 5 is provided by laminating a laminated film obtained by laminating a required resin material on one side 2b on the inner side of the container. The bonding part 7 is formed in the inner part of the through-hole 3 by being bonded to the layer 5 at the time of lamination, and the drinking part 8 is provided to penetrate the bonding part 7. As in the example shown in FIG. 5, a tab tape 6 is peelably attached so as to cover a portion of the outer protective layer 4 corresponding to the through hole 3 (for example, Japanese Patent Publication No. 6-49496). No.).

る。In the drinking part 1 shown in FIG. 5, the tab tape 6 has a sealing layer 9 on the outer protective layer side so that the heat sealing between the tab tape 6 and the outer protective layer 4 and the inner protective layer 5 is proper. And a sealing layer 1 made of the same material as the sealing layer 9 at least around the through hole on the container body side.
0 (single layer). In addition, in the drinking part 1 shown in FIG. 6, the tab tape 6 has a layer structure similarly having the sealing layer 9, and the outer protective layer 4 (laminated film) is made of the same material as the sealing layer 9 on the outer side of the container. And a laminated structure having the seal layer 11 of FIG. In the mouth part 1 shown in FIG. 6, a release layer 12 is formed as a device for preventing the base material from being affected when the tab tape 6 is peeled off.

照）。In the case where the container is designed so that the drinking part can be opened immediately, it is conceivable to provide the structure of the drinking part shown in FIG. 6 in the container. However, in the above-described structure in which the opened drinking port is covered with the tab tape, when the release layer is provided as described above, it is necessary to use a laminated film having the release layer. A laminated portion having a release layer is also formed on the outer surface of the container, which is uneconomical. Further, when the tab tape is peeled off, the surface layer portion of the outer protective layer is stretched, and there is a problem that stringing and whitening of the resin material easily occur (see FIG. 7).

It is an object of the present invention to make the appearance of the drinking section even after the tab tape is peeled off.

The window-attached film stuck around the through-hole and the laminated film that is located on the inner side of the container and protrudes into the through-hole are stuck together and covered, and inside the through-hole, A drinking water penetrating through a sticking portion between a window-attached film and the laminated film is disposed, and a tab tape that is peelably attached to the window-attached film and covers the drinking mouth with a heat seal . At the mouth, the window-attached film is laminated using a tough resin layer in the middle that does not follow the peeling of the tab tape.
An object of the present invention is to solve the above-mentioned problem by providing a drinking-mouth structure of a liquid container having a film structure .

Therefore, when the tab tape is peeled off, peeling occurs at a portion of the resin layer above the tough resin layer of the laminated film , and the resin layer portion pulled up to the tab tape side by the peeling remains only on the window sticking film. This eliminates the possibility that the outer protective layer side around the window application film is peeled off. In addition, window pasting fill

するものである。As described above, according to the present invention, there is provided a window in which an inner peripheral edge of a through hole opened in a base material is positioned outside the container of the base material and bonded around the through hole. The laminated film and the laminated film which is located on the container inner side of the substrate and protrudes inwardly of the through-hole are bonded together and covered, and inside the through-hole, the window-attached film and the laminated film, In the drinking part which arranges the drinking part penetrating the sticking part of the above, and covers the drinking part by heat sealing the tab tape which was peelably attached to the window sticking film, the window sticking film Is a mouthpiece structure of a liquid container characterized by having a laminated film structure using a tough resin layer in the middle that does not follow the peeling of the tab tape. In this way, the window-attached film is a laminate in which a tough resin layer that does not follow the removal of the tab tape is provided in the middle.
Due to the film structure , the resin layer remains on the substrate side when peeling off the tab tape, making it easy to peel off.Also, the resin part drawn by the tab tape does not reach around the window-attached film. Excellent practicality, such as the surface shape around the mouth is not impaired, and the heat sealing edge of the inner edge of the drinking mouth is not cut off, so that the penetration of the contents into the inner edge of the through hole can be reliably prevented. It has the effect that it has.
