Abstract

PROBLEM TO BE SOLVED: To prevent undesired leakage of a beverage or the like when a pack container is crushed. SOLUTION: The pack container employs a sheet material which has directivity in tear strength as a cover 5 glued to a pack container body 1 to cover an opening 4 provided on the body 1. The opening 4 of the pack container body 1 preferably comprising a paper pack for sealing a liquid is formed as a hole having an opening area sufficiently larger than a diameter of a straw 3 which is inserted into the pack container body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pack container suitable for enclosing a beverage.

[0002]

[Related Background Art] In recent years, a number of products in which beverages such as milk and juice are sealed in pack containers made of paper packs have been circulating. In this type of pack container, for example, a straw insertion port sealed with a seal is provided,
By inserting the straw into the insertion slot while breaking the seal with the straw, the beverage inside the straw can be sucked and drinkable.

[0003]

However, when crushing the pack container to discard the pack container after drinking the beverage, the beverage remaining in the pack container is often pushed out through a straw, May stain clothing. The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a pack container that can prevent unintentional leakage of a beverage or the like when the pack container is crushed.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, a pack container according to the present invention is provided with a tearing cover which covers an opening provided in the pack container body and is adhered to the pack container body. It is characterized by using a sheet material having directionality in strength. Preferably, as set forth in claim 2, the opening of the pack container body made of a paper pack for enclosing a liquid is formed as a hole having an opening area sufficiently larger than the diameter of a straw inserted into the pack container body. It is characterized by:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pack container according to an embodiment of the present invention will be described below with reference to the drawings, taking a paper pack for enclosing a beverage such as milk as an example. FIG. 1 is an external perspective view showing a schematic configuration of a pack container, and 1 is a pack container main body formed of a paper pack. The pack container body 1 has a shape that is folded into a substantially rectangular parallelepiped as a box-shaped container having a capacity of 200 ml, for example, and has a structure in which beverages such as milk and juice are filled and hermetically sealed. The upper portion (upper surface) of the pack container body 1 is provided with an opening 4 through which the straw 3 loaded in the bag 2 and attached to the side surface of the pack container body 1 is inserted. A sheet-like covering 5 is attached so as to cover the portion 4.

The opening 4 is formed as an opening region sufficiently larger than the diameter of the straw 3, for example, a circular hole having an inner diameter of about 3 to 4 times the outer diameter of the straw 3. The cover 5 that covers the opening 4 in a liquid-tight manner is made of a sheet material that has a directional direction of tear strength and is easily torn only in one direction due to an external force. It is provided by being attached around the opening 4 or the like. Here, an example is shown in which the cover 5 is attached to the outer surface of the pack container body 1, but may be attached to the inner surface of the pack container body 1. The pack container body 1 may have a so-called tetra-pack shape.

According to the above-described pack container, the obliquely cut end of the straw 3 is pierced into the cover 5 so that the cover 5 moves in one direction as shown in FIG. A tear 5a is formed at the opposing portions around the straw 3 by being torn. Then this rip 5a
Constitutes an air flow passage for opening the inside of the pack container main body 1, so that if the beverage inside the pack container main body 1 is sucked through the straw 3, air corresponding to the sucked amount will be broken 5.
a into the pack container body 1. As a result, it is possible to easily drink the beverage with only a light suction force.

[0008] Even when the peripheral surface of the pack container body 1 is unintentionally pressed and crushed, the air introduced into the pack container body 1 along with the beverage is cleaved by the aforementioned tear 5.
Since the beverage is only extruded through a, the beverage does not flow out through the straw 3 as in the related art. That is, in the conventional structure, when the beverage is sucked through the straw 3, air corresponding to the reduced amount of the beverage is introduced into the pack container body 1 through the straw 3 and then is lifted up. Accumulate. When the peripheral surface of the pack container body 1 is pressed and crushed in this state, there is no place for the air introduced into the pack container body 1 to escape, so that the beverage stored in the lower part of the pack container body 1 is pressed by the air. Then, it leaks through the straw 3. In this regard, the present structure does not have such a defect, and can facilitate the handling.

Note that the present invention is not limited to the above embodiment. For example, the material of the coating 5 is not only a paper material but also a sheet-shaped synthetic resin material or a metal foil, and further a metal film coated, provided that the tear strength has directionality. It can be adopted as appropriate. The shape of the pack container body 1 is not particularly limited. It is also possible to provide a similar opening 4 and a cover 5 for covering the opening 4 in a liquid-tight manner on a lid of a so-called cup noodle or the like, so as to facilitate injection of hot and cold water from a spout of a kettle. . In this case, a funnel or the like may be pierced into the cover 5, and if the funnel is removed, the crevices 5a of the cover 5 are closed, so that an effect such as facilitating processing after pouring hot water or the like is achieved. Can be In addition, the present invention can be variously modified and implemented without departing from the gist thereof.

[0010]

As described above, according to the present invention, since the sheet covering the opening of the pack container body is made of a sheet material having a directional tear strength, for example, the covering is made with a straw. When a breach occurs, a rupture through which air can flow around can be formed, so that it is possible to effectively prevent the outflow of undesired beverages due to simplification of the beverage and crushing, etc. A great effect can be achieved.
