Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a container that can contain liquids such as juice and coffee and can guarantee that the container is unopened.

<Prior Art> In conventional containers of this kind, an adhesive sealing tab piece that can be opened and resealed is simply stuck to the drinking spout.

As for the technology to prove that the package has been opened,
As shown in Japanese Unexamined Patent Publication No. 57-183950, a cut or a hole is made around the adhesive sealing tape that is pasted to the opening, and once the opening is opened, the adhesive sealing tape does not cut into the opening. Also described is a technique in which the hole is cut off and cannot be used for resealing.

<Problem to be solved by the invention> However, if the former type of adhesive sealing tab piece is attached to the drinking spout, the tab piece can be resealed to its original state after being opened, and therefore the inside can be sealed. There is a risk that foreign objects may get mixed in or the stored products may be replaced, and in the latter case, there are cuts and holes around the adhesive sealing tape, so when the tape is opened, the tape will be damaged. However, if a new similar tape is pasted to the opening again, it will not be obvious that the package has been opened at all, and the same problem as the former may occur.

The present invention relates to a completely new technique developed in view of the above-mentioned conventional problems.

<Means for solving the problem> The present invention is constructed by drilling a spout through which the stored liquid can be poured out in a part of the top plate or bottom plate, and pasting a sealing knob piece on this spout. In the paper container,
A half-cut line having a diameter larger than the knob piece is formed in the top or bottom plate around the opening direction of the spout, and the sealing knob piece is intersected with the half-cut line above the spout. This is a container with a drinking spout that is guaranteed to be unopened.

<Function> As described above, in the present invention, a half-cut line larger than the tab piece is provided around the opening start side of the top plate or bottom plate of the paper container with the drinking spout, and the tab piece is crossed with the half-cut line to form the drinking spout. Since it is configured by pasting it on top of the bottle, when the tab piece is peeled off to open the drinking spout, this half-cut line is automatically cut, making it possible to clearly indicate the state of the bottle once it has been opened as a trace.

<Example> To specifically explain an example of the container according to the present invention with reference to the drawings, in FIGS. 1 to 5, 1 is a paper container, and a straw is inserted into the bottom plate 2. A possible drinking spout 3 is perforated, and this drinking spout 3
A sealing tab piece 4 is pasted around the area to seal it.

Next, as is clear from the figure, the bottom plate 2 around the spout 3 in the opening direction is provided with an arcuate half-cut line 5 formed by a half-cut perforation line with a large outer diameter that reaches outward from the knob piece 4. has been done.

Since the container of the present application has the above-mentioned structure, once the spout 3 is opened by holding the tab piece 4, a part of the bottom plate 2 surrounded by the half-cut line 5 is removed from the main body together with the tab piece 4, as shown in FIG. Since it peels off, even if the tab piece 4 is later returned to its original state and resealed, the cut state of the half-cut line 5 will be clearly displayed as a trace, as shown in FIG.

As shown in FIG. 6, the above-mentioned half-cut lines 5 can be provided on both the left and right sides. In this case, one half-cut line 5 can be cut even if the knob piece 4 is peeled off from either the left or right direction.

<Effects of the invention> Since the container according to the invention has the above-mentioned structure and function, it is possible to prevent the opening from being resealed once it has been opened, protect and guarantee the stored items, and therefore consumers can feel at ease. The contents can be drunk, and the easy-opening function is not impaired, and the structure is simple and can be mass-produced at low cost, as it is only necessary to make a half-cut line around the drinking spout. It has many characteristics.

[Brief explanation of the drawing]

FIGS. 1 to 5 are explanatory diagrams showing the structure and function of the container of the present invention, and FIG. 6 is an explanatory diagram of another example. 1 is a container, 3 is a drinking spout, 4 is a knob piece, and 5 is a half-section line.

Claims (1)

[Scope of utility model registration request] In a paper container configured by having a drinking spout through which the stored liquid can be poured out in a part of the top plate or bottom plate and a sealing knob piece being attached to the drinking spout, the opening of the drinking spout is started. A half-cut line having a diameter larger than the knob piece is bored in the top plate or the bottom plate around the direction, and the sealing knob piece is pasted on the drinking spout so as to intersect with the half-cut line. A container with a drinking spout that is guaranteed to be unopened.
