Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a paper container containing a powder detergent, and more particularly to a container for a powder detergent that is easy to open and does not leak powder.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 8 and FIG. 9, a single blank is assembled and the front and both sides have a double structure of an outer box and an inner case, and are provided over the front 1 and both sides 2a, 2b of the outer box. A rectangular tubular detergent paper container in which a container body having a hinge portion 5 formed on the back surface 4 via an opening zipper 13 is divided into an openable / closable lid portion 6 and an inner case 7 has been used (Patent Published by the Agency, Collection of Well-known and Conventional Technologies (Packaging Industry), p. 291).

[0003]

[Problems to be solved by the device]

 However, in the conventional detergent paper container, the opening zipper 13 is parallel to the whole, and there is a problem that a force is required to cut the end portion 13a (see FIG. 8) of the opening zipper 13. Further, as shown in FIG. 10, the cutting portion between the opening / closing lid portion 6 and the inner case 7 is only provided with the arc-shaped intermittent cuts 8 in the cutting portion between the opening / closing lid portion 6 of the inner case 7 and A large force was required to tear the notch 8 due to the forced opening of the opening / closing lid portion 6, and it not only took time to separate the opening / closing lid portion 6 from the inner case 7, but also the container was often deformed. SUMMARY OF THE INVENTION The present invention solves the conventional problems described above, and aims to provide a detergent paper container that is easy to open, has a good lid after opening, and has no powder leakage.

[0004]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a double-layered structure of an outer box and an inner case by assembling from a single blank, and an unsealing provided over the front and both sides of the outer box. In a rectangular tubular detergent paper container which is divided into an opening / closing lid part having a hinge on the back side and an inner case via a zipper, the end of the opening / closing zipper is not adhered to the opening / closing lid part and the body part. A container made of detergent paper with a taper reaching the hinge part of the terminal part, and an arc-shaped cut in which the cut part with the opening / closing lid part on the inner side of the inner trunk is interrupted. It is also preferable that the two are connected to each other and the other end is set below the vicinity of the upper end of the adjacent arcuate cut.

[0005]

[Action]

 In the detergent paper container of the present invention, when the opening zipper is torn during opening, the end of the opening zipper is tapered, so that the opening zipper can be easily removed and the opening / closing lid and the inner body can be separated by 2 minutes. In addition, the peculiar shape of the cut part between the open / close lid and the inner side surface of the inner shell makes the resistance at tearing small and cutting is easy, and the open / close lid is separated without deformation and the closed state is maintained. Good and almost no powder leakage.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a development view in which a front surface 1 serving as an outer box and side surfaces 2a and 2b are connected to each other through a fold line, and the side surface 2a is connected through a fold line. The back surface 4 is connected. An inner trunk side surface 7c that overlaps the inside of the side surface 2b, an inner trunk front surface 7a that overlaps the inside of the front surface 1, and an inner trunk side surface 7b that overlaps the inside of the side surface 2a are connected to the rear surface 4 through the sequential fold line. The box body is formed by bonding 7c and the side surface 2b. An opening zipper 3 is provided over the front surface 1 and side surfaces 2a and 2b which are outer boxes, and the opening zipper 3 is opened and closed at a non-bonded end between the side surface 2a which is an outer box and the inner body side surface 7b when the container is assembled. It is tapered to reach the hinge portion 5 of the lid portion 6 (see FIG. 2). Further, the open / close lids 6 and 6 are connected to the front face 1 and the back face 4 via folding lines, and are double-attached at the time of assembly. Reference numerals 10 and 10 denote sticking pieces of the inner opening / closing lid portion 6. In FIG. 1, 11 and 11 are double-bonded bottom faces connected to the front face 1 and the back face 4 via folding lines, 12 and 12 are sticking pieces, and 14 and 14 are inner body side faces 7c and opening / closing lid parts. 6 and a reinforcing piece with the bottom surface 11 are shown.

Further, the cutting portion formed on the inner body side surface 7C for separating the opening / closing lid portion 6 from the inner body side surface 7c is forcibly cut and opened the opening / closing lid portion 6 as shown in FIG. However, as shown in FIG. 4, this cutting portion is an arcuate cut 15 that is interrupted, and one end of a U-shaped cutout 16 is connected to the lower end of the upper arcuate cut 15 and the other end is an adjacent arcuate cut. It is assumed that it is set on the lower side near the upper end of the groove 15, and the force in the direction of the arrow makes it possible to easily perform vertical tearing as shown in FIG. This cutting portion will be further described. As shown in FIG. 6, the other end A of the U-shaped cut 16 whose one end is connected to the lower end of the intermittent circular cut 15 is near the upper end of the adjacent circular cut 15. The point B is located closer to the lower side of the point B, and the point B is inside the upper point C of the arcuate cut 15. Therefore, when a tearing force is applied, as shown in Fig. 7, it starts to tear from the point A and easily reaches the arcuate cut 15 near the point B, the tearing direction is stable, and it is easy to open without requiring a large force as in the past. To be done. The length of the arcuate cut 15 and the number of U-shaped cuts 16 are arbitrarily determined depending on the size and thickness of the container.

[0008]

[Effect of device]

 As described above, the detergent paper container of the present invention is easy to open because the opening zipper is tapered, and the open / close lid is easily cut in a stable direction from the inner case and is in the closed state. It is good and has no powder leakage, and because it is made entirely of paper, it does not adversely affect environmental problems.
