Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a liquid container, particularly a liquid paper container equipped with a pouring hole into which a straw or the like can be placed.

[Conventional technology]

Conventionally, this type of container has a structure in which a multilayer sheet is punched out and an insertion hole for a straw is provided in advance, and this insertion hole is removably covered with tab tape, As shown in Publication No. 34752, the spout hole is provided with a cut that does not reach the surface layer of the sheet, and a cut is made on the surface layer side so as to surround the spout hole. A removable tab part is provided by making a notch in the surface layer side so as to surround the container body and covering the pouring hole part, and when the tab part is peeled off, an insertion hole can be formed, and a part of the notch part is inserted into the container body. , and the notch is located between the crease lines as shown in Japanese Utility Model Publication No. 62-26345. There were also some configurations.

[Problem that the invention attempts to solve]

However, the configuration in which the insertion hole is covered with the above-mentioned tab tape requires a manufacturing process of attaching a tab tape made of aluminum foil or the like, which has the disadvantage of increasing manufacturing costs. Further, in the case where the notch forming the tab portion is located in the mountain-fold ruled line portion, it is not possible to perform the operation of adding the ruled line and making the notch at the same time. In other words, when creating ruled lines and notches using the flat pressure press method, grooves are usually created in the plywood using a laser, etc., and a strip-shaped metal piece is placed in this area for the ruled lines.
If it is a cut, a sharp metal piece is embedded and used as a press mold. When the sheet is pressed against this press die, ruled lines or cuts are formed on the sheet. Therefore, if the ruled line portion and the notch match, it is not possible to attach a metal piece for the ruled line portion and a metal blade for the notch to the same press mold, and the press molds must be prepared separately. . There is a problem in that the number of manufacturing steps increases as described above.
Furthermore, when a notch is made and then a ruled line is added on top of the notch, the notch becomes buried due to the pressing force, resulting in a problem that it becomes difficult to hold the finger.

If the pair of ruled lines are spaced apart, when the sheet is folded, the top and body parts of the container body including the area between the ruled lines will be gently curved, which will impair the appearance of the container. There is a problem that the ruled line portion becomes difficult to fold. This creates a state in which stress is constantly applied to almost the entire curved surface, and there is a possibility that delamination at the tab portion will naturally progress.

[Means for solving problems]

The present invention was made in consideration of the above-mentioned conventional problems, and a spout hole is provided by making a cut from the inside of the upper surface of the container body made of a multilayer sheet that does not reach the surface layer. A notch that does not reach the back layer part is made from the side so as to surround the spouting hole part, and a tab part that is continuous with the surface layer part is provided inside the notch, and the spouting hole part can be opened when the tab part is peeled off. A liquid container configured as shown in FIG. Provided is a liquid container, characterized in that a notch is made in a straight line with the mountain-fold ruled line part and does not reach the back layer part, and the notch in the tab part is arranged close to the notch in the part between the ruled lines,
This solves the problems of the conventional method.

[Effect]

In the present invention, by bending the mountain-fold ruled line part when assembling the container, the notch between the mountain-fold ruled line parts is opened, and the exposed cut edge makes it easy to roll up the part between the ruled lines. The part serves as a finger grip for peeling off the tab part, and prevents natural delamination from affecting the tab part.

〔Example〕

Next, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 4.

In the figure, reference numeral 1 indicates a Goebelt-type liquid container, and this liquid container 1 is made of a three-layer sheet with an intermediate layer between a surface layer and a back layer. For example, a polyester film can be used.

A pair of opposing notches 2 are provided in one of the sloped roof surfaces 10 located above the liquid container 1 . This cut 2 is made in the surface layer part so as to reach the middle layer part, and this cut 2 is arranged on the lower edge side of the roof slope part 10,
By bending along the lower end side of the roof slope part 10, a peelable tab part 3 is defined in the surface layer of the roof slope part 10.

Further, in the back layer portion corresponding to the tab portion 3, an insertion hole portion 5 is provided by making a circular notch 4 reaching the middle layer portion at a position relatively surrounded by the notch 2. . The insertion hole is opened by peeling off the tab portion 3.

A pair of discontinuous mountain-fold ruled line parts 5 are provided between the roof slope part 10 and the body part 11. In the area 6 between the ruled lines of the mountain-fold ruled line, a notch 7 is provided that is lined up in a straight line with the mountain-fold ruled line 5 and does not reach the back layer. When 6 is bent, the cut 7 opens and the cut edge 70 is exposed. The curved lower end side of the notch 2 is disposed close to the notch 7 in a state where it is not connected, that is, the part 6 between the ruled lines and the tab part 3 which are made easy to roll up at the notch 7 are disposed close to each other. The cut edges 70 serve as fingerholds to roll up the portion 6 between the ruled lines, and then the tab portion 3 can be peeled off. Note that each end of the notch 7 may be bent toward the tab portion side in order to further improve the rolling up of the portion 6 between the ruled lines.

Further, as shown in FIG. 4, the lower end of the notch 2 may be arranged close to each end of the notch 7, and the area between the ruled lines 6 can be easily rolled up.
The tab portion 3 and the tab portion 3 may not be separated by a cut.

[Effect of idea]

As explained above, according to the present invention, a spout hole is provided by making a cut from the inside of the upper surface of the container body made of a multilayer sheet that does not reach the surface layer, and reaches from the surface layer side to the back layer. In the liquid container, a notch is made to surround the spouting hole, a tab part continuous to the surface layer is provided inside the notch, and the spouting hole can be opened when the tab part is peeled off. A pair of mountain-fold ruled lines spaced apart is provided between the top surface of the container body and a body surface continuous to this top surface, and a pair of mountain-fold ruled lines located between the ruled lines of the mountain-fold ruled lines are arranged in a straight line with the mountain-fold ruled line. The notches in the tab section are placed close to the notches in the area between the ruled lines, so that when the container is assembled, the edges of the notches in the area between the ruled lines are exposed and the incisions do not reach the ruled line. The space between the lines can be rolled up very easily, and the rolled up space between the ruled lines acts as a finger catch to easily pull up the tab. Furthermore, since there are notches between the ruled lines, the container can be bent in a straight line, and the tab portion will not be inadvertently peeled off, and the appearance of the container will not be impaired. Furthermore, only one press mold is required, and the mountain-fold ruled line and the notches that line up with the mountain-fold ruled line can be obtained at the same time in one press, and the manufacturing process is not complicated, resulting in excellent practical effects. It is something.
