BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage paper pack containing juices, soft drinks, milk and the like, and more particularly to a beverage paper pack which facilitates pouring of a beverage enclosed in a pack body.

[0002]

2. Description of the Related Art In a large-sized beverage paper pack, for example, for 1 liter, which is used to pack and sell juices, milk, etc., as shown in FIG. ) 22, the ears 22 are overlapped, and the tip of the ears is cut along the cutting guide line 23 with a cutter or the like, so that the beverage in the pack body 21 can be poured out. There is.

[0003]

As described above, in the conventional beverage paper pack, the beverage cannot be poured out and the seal is cut unless the ears 22 are raised and then cut. There are problems that it is necessary to prepare a cutter or the like, and it takes time to open the spout.

The present invention has been proposed in order to solve the problems of the prior art, and provides a beverage paper pack in which the spout can be easily opened and the beverage in the pack body can be poured out. The purpose is to

[0005]

In order to achieve this object, a beverage paper pack according to the present invention has a mouth opening in the upper plate portion of the box-shaped pack body, and the upper plate portion is closed to close the mouth portion. It is curved downward when the top seal is attached, but when the top seal is peeled off, a hemispherical base that bulges upward from the mouth due to repulsive force or upward pulling force is provided. It has a structure in which a spout is provided directly to or through a telescopic tube.

[0006]

According to the above-mentioned structure, the spout is accommodated in the main body when the mouth is closed by the top seal, and when the top seal is peeled off, the spout projects upward from the mouth. Liquid can be poured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of a beverage paper pack according to the present invention will be described in detail below with reference to the drawings.

An embodiment of this beverage paper pack brick is shown in the perspective view of FIG. 1, and a vertical sectional view of the spout portion is shown in FIG.

In the figure, reference numeral 1 is a box-shaped pack body mainly made of paper, and a circular mouth portion 7 is opened on one side of the upper plate portion 1a.

The mouth portion 7 is provided with a hemispherical base 4 in which an outward flange 4a is adhered to the lower surface of the upper plate portion 1a around the mouth portion 7. The base 4 is made of plastic so that It is designed so that it can be swollen upwards and downwards by a snap action by the pulling force to the and downward pressure.

The base of the pouring pipe 3 made of a flexible pipe 5 such as a bellows is connected to the central portion of the base, and the pouring pipe 3 communicates with the inside of the main body, and the tip of the pouring pipe 6 is connected to the spout 6. Is a stopper 8
Is detachably attached.

Before opening, the expansion pipe 5 of the pouring pipe 3 is contracted, and the base 4 is pushed into the main body 1 while being inverted into a bowl shape, and the contracted expansion pipe 5 is accommodated inside the base 4. Has been done. In this state, the upper surface of the stopper 8 is the pack body 1
The height will be the same as or slightly lower than the upper surface of. Before opening, the mouth portion 7 is closed with a protective top seal 2 attached to the upper surface of the main body.

The base 4 is bulged and curved downward by the upward swelling output being pressed by the top seal, and when the top seal is peeled off, it is automatically swelled upward by elastic force. There are cases.

In the beverage paper pack thus constructed, the top seal 2 is first peeled off before use, and the pour pipe 3 is used.
Expose. Then, the upper portion of the pouring pipe 3 is picked up and the bellows-shaped telescopic pipe 5 is pulled out upward as shown in FIG. By doing so, the base 4 is reversed by a snap action and bulges like an inverted bowl. After that, as shown in FIG. 5, the expansion tube 5 is appropriately angled so that it can be easily poured, and then the plug 8 is removed.
Open the spout 6. As a result, the beverage 9 in the pack body 1 can be poured out from the pouring port 6 into a cup or the like.

If the top seal prevents the base seal from inverting and bulging upward, when the top seal is peeled off, the base seal is automatically inverting and bulging upward due to the elastic inverting force.

After pouring the beverage, the spout 6 is closed with a stopper 8 and then the upper portion of the pouring pipe 3 is pushed down to expand the expansion pipe 5.
To be fully compressed. At this time, the base 4 is flipped by the snap action and pushed into the main body 1.
The expansion tube 5 is housed inside. In this state, the beverage left over can be stored in a refrigerator or the like.

As described above, in the beverage paper pack of the present invention,
The spout 6 can be opened with one touch, and the spout 6 can be easily sealed after the beverage is poured.

Next, another embodiment shown in FIG. 6 will be described.
In this embodiment, the spout 6 is opened at the top of the base 4 without providing the expansion tube, and thus the expansion and contraction of the spout tube 10 is made with respect to the main body 1. Stopper 8
The broken pouring tube 10 is pushed into the main body 1.

Although the pouring pipes 3 and 10 are provided on the upper surface of the main body 1 in the above-described embodiment, the pouring pipes may be provided on the upper side of the main body 1.

[0020]

As described above, according to the present invention, when the top seal is peeled off, the downward curving base is automatically or reversely curving by pulling and bulging upward, and the spout is projected from the mouth. Since the beverage in the pack body can be poured out, it is not necessary to prepare a cutter or the like to open the spout as in the conventional case, and there is an advantage that the spout can be easily opened.

Further, when storing the drink left over, it suffices to plug the spout and push the pour tube into the main body, which is more hygienic and easier to seal the spout than ever before.
