Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to the top structure of various rectangular paper bag containers such as cardboard, laminated paper, and inner bag.

(Prior Art) It is generally known that a paper container is provided with a strap-like handle portion.

However, in order to provide a hanging portion, that is, a carrying hand into which all or partial fingers can be inserted, it is necessary to provide a folding line or a punched portion of the carrying ring portion on the sheet for assembling the paper container, and thus the sheet itself. Instead of a straight line, a special parabolic broken line or cutting line is applied, which complicates the structure of the seat itself. Furthermore, if there are many parabolas, its assembly is not easy. In addition, in the case of the hanging method, in the case of a paper container, there is also a drawback that damage is likely to occur due to the repeated operation of the carrying part.

(Problems to be solved) In the present invention, it is necessary to cut the top part of the paper container by using the line of the rectangular sheet as it is with a parabola or a diagonal line of the special ring part,
Another object of the present invention is to provide a top structure of a container which can be assembled from a rectangular sheet only by folding lines without the punched portion.

Furthermore, the present invention provides a grip portion that can be gripped between the thumb and other fingers when closed by providing a special inner and outer folding line, and provides a grip portion that does not induce damage due to repeated use, as in the case of a general carrying hand. It is an object of the present invention to provide a top structure of a container.

(Means for Solving Problems) In order to achieve the above-mentioned object, in the top structure of the container according to the present invention, the container having a rectangular cross section with side walls 1, 2, 3, and 4 is used. Upper edge 1 of the side walls 1, 2, 3, 4
Each of a, 2a, 3a, 4a has a top structural piece 6, 7, 8, 9 which is square and has an inward folding line b parallel to the upper edge at an intermediate position.
, And the inner structure lines 6a, 6b, 8a, 8b are formed on the top structure pieces 6 and 8 in an isosceles right triangle with the inner line b as the bottom.
And the top structure pieces 7 and 9 are formed into isosceles right triangles having upper edges 2a and 4a as bases, and outward bending lines 7a, 7b and 9a,
9b and external bending lines 7c and 9 perpendicular to the apexes of the triangular shape
c, and each top structure piece 6 above the inner fold line b,
The connecting lines 10, 11, 12, 13 and the lower edges 1a, 3a between 7, 8 and 9 are outer bending lines, and the connecting line 14 between the respective top structure pieces 6, 7, 8, 9 under the inner bending line b, 15, 16, 17
The lower edges 2a and 4a are characterized by an inner fold line and the top structure of the container.

(Example) Next, an example of an embodiment of the container top structure of the present invention will be described in detail.

The seat portion at the top of the container according to the present invention includes side walls 1, 2, 3, 4 which are rectangular in cross section at the time of assembly, and top component pieces 6, 7, 8, 9 of each square, and an upper edge 1a of the side wall. 2a, 3a,
Connected by 4a.

The sheet has a side wall glued portion 5 and a top glued portion 5a.

The top component pieces 6, 7, 8 and 9 are provided with inner folding lines (front surface contact direction) and outer folding lines (back surface contact direction) in a special direction.

The inner fold lines are 2a, 4a, b, 6a, 6b, 8a, 8b and 14, 15, 16, 17.

The outer line is 1a, 3a, 7a, 7b, 7c, 9a, 9b,
9c and 10, 11, 12, and 13. When the glued parts 5, 5a are glued to the corresponding side walls 1 and the top component piece 6, the container of rectangular cross section shown in FIG. 2 is completed.

In this case, the connecting lines 10, 11, 12, 13 and the inner folding line 6
The a, 6b, 8a, and 8b are not bent and have a planar shape (actually, there is some refraction due to the broken line).

At this time, since the connecting lines 10 and 13 and 11 and 12 which face each other are outward bending lines, they are in a slightly open direction. Therefore, when the container content is liquid or fine particles, the container is tilted from this slightly open position. The outer bending line 7c or 9c can be discharged as an outflow gutter.

If the container content is large, such as flakes, then a large opening can be obtained by pulling up the top piece 6,8.

Next, when the state of FIG. 2 is changed to the closed state of FIG. 3,
Grasp the appropriate parts of the side walls 1, 2, 3, 4 of the container with the fingers of one hand,
With the fingers of the other hand, the upper edge 2a of the top component pieces 7, 9 and the surrounding portion of the outer folding lines 7a, 7b, and the upper edge 4a, the outer folding lines 9a, 9
b It can be easily achieved by applying an upward pressing force to the surrounding portion. In other words, the inner folding lines 14, 15, which were in the unfolded state,
16, 17 and 6a, 6b, 8a, 8b and fold line 1
0, 11, 12, and 13 easily bend in each folding direction,
Thus, on both sides of the center of the apex facing each other, flat carrying parts protruding from the both sides are formed.

The container containing the contents before use is the top component pieces 7, 9
The edges of the may be sealed with suitable adhesive tape. The container can be carried by nipping the overlapping portions A and B of the top component pieces 7 and 9 as a substitute for a hand.

(Effects of the Invention) The top structure of the container of the present invention is such that the rectangular top component pieces 6, 7, 8 and 9 connected to the seat side wall are not curved but are provided with straight inner and outer folding lines. A lid can be provided that can be opened and closed very easily.

That is, the inner folding lines 2a and 4a are used as hinge lines to form the outer folding line 1.
0, 11, 12, 13 can be bent from the flat position to the outer folding position to open and close as a lid-corresponding portion.

Furthermore, the container can be carried by sandwiching the overlapping portions A and B of the top component pieces 7 and 9 as a substitute for a hand.

Therefore, since the top structure portion of the container made of the sheet does not require a special curved portion or cutout portion for the carrying hand, it is convenient that the sheet itself can be easily manufactured.
