DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a packaging container.

[0002]

2. Description of the Related Art Conventionally, liquid foods such as milk, soft drinks, etc.
Generally, it is sold in a packaging container of a brick type, a polyhedral type or the like made of a packaging material. In a packaging container having a capacity that can be completely consumed at one time, a spout is formed in the top wall, and the spout is covered with a pull tab.

FIG. 2 is a perspective view of a conventional packaging container.

[0004] In the figure, 10 is a packaging container for storing liquid food, 12 is a packaging container body, 44 is a top wall of the packaging container body 12, 38 is a front wall of the packaging container body 12, 29.
Is a side wall of the packaging container body 12, a spout 21 formed of a punch hole is formed in a spout portion 37 set at a predetermined position of the top wall 44, and the spout 21 is covered by a pull tab 51. In this case, a person who intends to drink the liquid food, that is, a drinker, pulls the pull tab 51 from the packaging container body 12, puts his lips on the spout 21 opened, and applies the liquid food. Can be drunk directly.

[0005] The pull tab 51 has a larger area than the spout 21, and when attached to the packaging container body 12,
A horizontal portion 75a extending along the top wall 34 and covering the periphery of the spout 21 to prevent contamination; and a vertical portion extending along the front wall 38 and serving as a knob when the pull tab 51 is peeled off. 75b.

[0006]

However, in the conventional packaging container, when the lips are applied to the opened spout 21 and the liquid food is directly drunk, the pull tab has a rectangular shape, and Since the top wall is fixed so that the rectangular short side of the pull tab comes on the ridge line intersecting with the front wall of the packaging material, the ridge line touching the lips is not covered with a sufficient length. Since there is a possibility that dust or the like may adhere to the unexposed portion, hygiene is insufficient. In addition, the pull tab extends along the front wall 38, and the vertical portion 75b serving as a pinch when the pull tab 51 is peeled off is not a sufficient length (area).

[0007] The present invention solves the problems of the conventional packaging container, improves the sanitary aspect of the spout, and provides a pull tab that sufficiently covers a portion where the lips touch when the lips touch the container. The present invention also provides a packaging container capable of minimizing the cost of the pull tab and having the shape of the pull tab visually sharp and fresh.

[0008]

For this purpose, in the packaging container according to the present invention, the spout provided on the top wall of the packaging material of the packaging container covers the spout from the front side of the top wall of the packaging material. A packaging container comprising: a pull tab adhered to the inner wall of the packaging material; and an inner tape adhered from the back side of the packaging material top wall, wherein the pull tab has a rectangular shape, and the packaging material top wall is in front of the packaging material. A rectangular diagonal portion of the pull tab is formed so as to cover the ridge line intersecting the wall. That is, since the length of the diagonal line of the rectangle is longer than each side, the maximum length (diagonal line) of the pull tab itself can be covered by the ridge line, so that the sanitary property by the pull tab is maximized. Things.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a diagram showing an initial state of a packaging container according to an embodiment of the present invention, and FIG. 3 is a diagram showing an opened state of the packaging container according to the embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a packaging container, and 12 denotes a packaging container body. The packaging container body 12 has a body 31 having a substantially octagonal cross section, and extends upward from the body 31. The lower end has a substantially octagonal shape, the upper end 32 has an upper end having a substantially square shape, and extends downward from the body 31, and the upper end has a substantially octagonal shape,
The lower end has a lower end having a substantially square shape. The body 31 includes a front wall 34, a rear wall (not shown), and two side walls 35 (in FIG.
Just show. ), And four trunk connecting walls 36 (one of the trunk connecting walls in the figure) disposed between the front wall 34 and each side wall 35 and between the rear wall and each side wall 35. 36 is shown). The front wall 34, the rear wall, the side wall 35, and the trunk connecting wall 36 are all rectangular.
It has the shape of a shape.

The upper end 32 has a top wall 44, a front wall 38 connecting the top wall 44 and the front wall 34, a rear wall (not shown) connecting the top wall 44 and the rear wall, Two side walls 29 connecting the top wall 44 to each side wall 35 (only one side wall 29 is shown in the figure), and four connections connecting the top wall 44 to each body connection wall 36. The wall 40 (one of the connecting walls 40 in the figure)
Just show. ). Each of the front wall 38, the rear wall, and the side wall 29 has a trapezoidal shape with the upper bottom placed down, and the connecting wall 40 has a triangular shape with one vertex placed on the top wall 34. . Reference numeral 46 denotes a seal formed in the center of the top wall 44, and 47 denotes an ear.
Is fused to the side wall 29.

The lower end connects a bottom wall, a front wall connecting the bottom wall to the front wall 34, a rear wall connecting the bottom wall to the rear wall, and a bottom wall to each side wall 35. It consists of two side walls, and four connecting walls connecting the bottom wall and each body connecting wall 36.

The packaging container body 12 is formed by molding a packaging material. For this purpose, a fold is formed in the packaging material in advance, and the packaging material is bent along the fold to form a prototype container. Subsequently, a predetermined molding process is performed on the prototype container to form a packaging container body 12 having a final shape. The packaging material is made of a laminated body having flexibility, and has a paper base (not shown), an outermost layer (not shown) made of polyethylene resin or the like coated on the surface of the paper base, and a back surface of the paper base. A barrier layer (not shown) having a gas barrier property, and an innermost layer (not shown) made of polyethylene resin or the like coated on the back surface of the barrier layer.

By the way, at a predetermined position on the top wall 44, for example, a spout portion set at a predetermined position substantially at the center of a position close to a boundary line L1 (ridge line) between the top wall 44 and the front wall 38. An outlet 21 composed of a punch hole is formed, and a pull tab 51 is adhered by fusion so as to cover the outlet.

The pull tab 51 is made of aluminum foil, and has a gas barrier property, an outermost layer made of polyethylene resin or the like coated on the surface of the barrier layer, and a back face of the barrier layer. And an innermost layer made of polyethylene resin or the like. The pull tab 51 has a larger area than the spout 21 and extends along the top wall 44 when affixed to the packaging material, and covers the periphery of the spout 21 to prevent contamination. , And a vertical portion 75 to be picked when the pull tab 51 is peeled off.
b. Further, the inner tape 77 is adhered from the back side of the packaging material on the top wall 44, and is sealed with the pull tab 51 and the periphery of the spout 21.

The pull tab has a rectangular shape, and a diagonal portion of the rectangular shape, for example, having the same length as the length of the ridge line, coincides with the ridge line L1 intersecting the front wall of the packaging material on the top wall of the packaging material. Is formed by being adhered to. Here, in consideration of the fact that the pull tab is continuously supplied to each packaging container and that the spout is disposed substantially at the midpoint of the ridge line, the shape of the pull tab is preferably a square material (area). ) And the total cost of the pull tab is minimized.
More specifically, regarding the method of supplying the pull tabs, if the pull tabs are square, if the pull tabs are supplied at an angle of 45 degrees with respect to the ridge line, each apex angle of the pull tabs becomes 9
Because the pull tabs are at 0 degrees, each pull tab can be placed on the supply board (supply board for the pull tabs to be transported) without the need for extra space continuously, so there is no loss of materials (area) used and the total cost of the pull tabs is reduced. That is to minimize. Therefore, when the length of the ridge line L1 is L, one side is substantially L
A rectangle (square) with a length of /1.41 (square root of 2 = 1.41) is optimal.

The horizontal portion 75b of the pull tab 51
Has an area larger than the spout 21 on the top wall,
2, it is fixed to the top wall. However, a spot other than the spout 21 may be partially spot-fixed, and the substantially vertical portion 75 a extending along the front wall 38 also has the pull tab 21.
Partial spot fixation may be used for easy peeling. Therefore, unlike the conventional packaging container, when the lip is applied to the opened spout 21 and the liquid food is directly drunk, the pull tabs are all on the ridge line L1 intersecting the packaging material front wall on the packaging material top wall. Since it is fixed so as to be covered, there is no adhesion of dust and the like, so that it is sanitary when the lips touch.

Therefore, as shown in FIG. 3, the inner tape can be broken by pulling the pull tab 51 off the packaging container 10, the spout 21 can be opened, and the packaging container 10 can be opened. Then, when the lip is applied to the opened spout 21 and the liquid food is directly drunk, the present invention solves the problems of the conventional packaging container, improves the sanitary aspect of the spout, A packaging container capable of providing a pull tab that sufficiently covers a portion where the lip touches when the lip touches the container, and a shape capable of minimizing the cost of the pull tab. Further, when the container is viewed from above the front of the container, the pull tab looks like a diamond, and the sharpness and freshness are visually perceived, thereby increasing the commercial value.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.

For example, the spout 21 is formed by a punch hole at the spout, and is opened by peeling off the pull tab 51.
In 4, the spout may be formed by a broken portion including a perforation, a prelaminate, a half-cut portion, and the like, and the spout may be opened by breaking the broken portion as the pull tab 51 is pulled up. In that case, the inner tape becomes unnecessary. The method for fixing the pull tab may be thermocompression bonding or hot melt adhesion. In addition, the length of the diagonal line of the pull tab is not necessarily the same as the ridge line L1, and may be determined in consideration of the hygiene. Further, the shape of the pull tab may be a rectangle (square or rhombus) or a deformed rectangle (a figure in which each side of the rectangle becomes a curved side in a direction in which the area of the figure increases).

[0022]

As described above in detail, according to the present invention, the packaging container has a pull tab attached to the spout from the front side of the packaging material constituting the top wall. The pull tab has a rectangular shape, and is formed by being fixed so that a diagonal portion of the rectangular shape coincides with a ridge line on the top wall of the packaging material that intersects the front wall of the packaging material. In other words, since the length of the diagonal line of the rectangle is longer than each side, the pull tab can cover the maximum length (diagonal line) of the pull tab itself with the ridge line. Can be provided. In addition, the pull tab extends along the front wall 38, and the vertical portion 75b serving as a knob when the pull tab 51 is peeled off can also provide a sufficient length (area) in a sanitary manner.

Accordingly, it is possible to provide a pull tab that improves the hygiene of the spout portion and sufficiently covers the portion where the lip touches when the lip is applied to the spout 21 that is opened and the liquid food is directly consumed. And a shape that minimizes the cost of the pull tab. Further, when the container is viewed from the front of the container, the sharpness and freshness can be visually sensed, thereby increasing the commercial value.
