BACKGROUND OF THE INVENTION
The present invention relates to a powder detergent paper container.
[0002]
[Prior art]
In detergent containers, paper containers are used for incineration at the time of disposal. In Japanese Patent No. 2656903, a paper container in which a lid is hinged to a container main body, the latching tongue piece adhered to the outer surface of the opening edge of the container main body is peeled off and raised, and is provided inside the lid. The stop recess can be locked to the raised tongue piece raised when the lid is closed. Accordingly, the lid is prevented from floating in the opening direction from the closed position by the repulsive force of the hinge, and it is possible to avoid the moisture absorption and solidification of the detergent.
[0003]
[Problems to be solved by the invention]
{Circle around (1)} The locking tongue piece adhered to the outer surface of the container body is peeled off, and this peeling mark impairs the appearance of the container.
[0004]
(2) The strength of the container body and the locking tongue piece is reduced by peeling off the locking tongue piece.
[0005]
(3) The raised locking tongue piece is provided with a restoring behavior to the outer surface side of the container body that has been bonded before being raised, and this acts as a locking release behavior that disengages from the locking recess of the lid. The reliability of the lock is impaired, and the detergent is likely to absorb moisture.
[0006]
An object of the present invention is to improve the reliability of the locking of the lid without impairing the appearance and strength of the container.
[0007]
[Means for Solving the Problems]
The present invention is a powder detergent paper container in which a lid is hinged to the back plate of the container body, and an adhesive strip provided on the lower edge of the front plate of the lid can be attached to the front plate of the container body. The front edge of the engagement piece , which is folded back until the lid sticking piece is turned inward along the back surface of the front plate with the lower edge of the front plate as a fulcrum, can be locked to the outer surface of the side wall of the container body when the lid is closed And a plurality of locking lines intersecting the opening direction of the lid are provided on the outer surface of the container body so that the leading edge of the engaging piece can be locked .

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the powder detergent paper container 10 includes a container main body 11, a lid 12, and a sealing paper 13.
[0009]
The container main body 11 is assembled by folding only a paper or a material in which a plastic film is laminated using paper as a main material, and includes a front plate 11A, a back plate 11B, both side plates 11C and 11C, and a bottom plate 11D. As shown in FIG. 2, the container body 11 is provided with inner folding flaps 11G at the opening edge portions 11F of the front plate 11A, the rear plate 11B, and the side plates 11C and 11C forming the opening 11E. It is inwardly bonded.
[0010]
The lid 12 is assembled by folding only a paper or a material laminated with a plastic film using paper as a main material, and includes a front plate 12A, a rear plate 12B, side plates 12C and 12C, and a top plate 12D. The lid 12 is provided with an adhesive piece 12E (available as a knob portion at the time of opening) attached to the front plate 11A of the container main body 11 at the center of the lower edge of the front plate 12A, and a hinge coupling portion on the rear plate 12B. 12F is provided, and a glued flap 12G connected to both side plates 12C and 12C is attached to the inner surface of the front plate 12A.
[0011]
The paper container 10 is configured by hinge-joining a hinge coupling portion 12F of the lid 12 to a back plate 11B of the container body 11. At this time, as shown in FIG. 2, the paper container 10 folds the sticking piece 12 </ b> E provided on the front plate 12 </ b> A of the lid 12 inward to form the engagement piece 31 of the present invention. It can be locked to the outer surface of the face plate 11A. On the other hand, the outer surface of the front plate 11A of the container main body 11 to which the engagement piece 31 of the lid 12 is locked is defined as an opening resistance surface 32 formed with a plurality of half-cut lines that intersect the opening direction of the lid 12. Yes. Thus, when the lid 12 is reclosed after the sticking piece 12E of the lid 12 is peeled off from the front plate 11A of the container body 11, the engaging piece 31 of the lid 12 is engaged with the opening resistance surface 32 of the container body 11 by friction. It is locked with a feeling of moderation (locking force and locking sound) based on the locking action by the unevenness, and the lid 12 is prevented from floating in the opening direction by the repulsive force of the hinge coupling portion 12F, and the powder of the contents Avoid hygroscopic solidification of body detergents.
[0012]
Note that the paper container 10 has a sealing paper 13 that seals the opening 11E of the container body 11 attached to the outer surface of the front opening 11A, the back plate 11B, and the side openings 11C, 11C with a certain width. (FIG. 1), and the powder detergent of the contents can be sealed at the distribution storage stage.
[0013]
Therefore, according to this embodiment, there are the following operations.
(Operation corresponding to claim 1)
(1) The engagement piece 31 provided on the lid 12 utilizes the sticking piece 12E that is inherently provided on the lid 12, and an opening resistance surface 32 provided on the container body 11 can be provided on the container body 11 in advance. Therefore, when the engagement piece 31 and the opening resistance surface 32 are used, the appearance of the paper container 10 is not impaired, and the strength of the container body 11 and the lid 12 (including the engagement piece 31) is not further reduced.
[0014]
(2) Since the engagement piece 31 is used by being folded inside the lid 12 and has a restoring behavior that spreads outward before being folded back, the engagement piece 31 is strongly locked against the opening resistance surface 32 of the container body 11. It acts as an acceleration behavior, improves the certainty of the lid 12 lock, and improves the moisture absorption prevention of the detergent.
[0015]
(Operation corresponding to claim 2)
(3) Since the opening resistance surface 32 is formed with a plurality of half-cut lines intersecting with the opening direction of the lid 12, the engagement action by friction with the engagement piece 31 and the engagement action by unevenness Secure the lid 12 to make it more secure.
[0016]
(Operation corresponding to claim 3)
(4) Sealing paper 13 is an outer surface following the upper end surface of the opening edge portion 11F of the container body 11, and can be attached to a range of a certain width separated from the opening resistance surface 32. The opening resistance surface 32 is opened when the sealing paper 13 is opened. It will not be damaged by peeling off the surface layer around. Therefore, the opening resistance surface 32 is not weakened while ensuring sealing with the sealing paper 13.
[0017]
In addition, the opening resistance surface 32 raises the frictional force with the engagement piece 31 of a surface rather than the smooth surface of the material of a container main body, and it replaces with the said embodiment, and a plurality of ruled lines (FIG. 3 (A)) It may be composed of Those formed with embossing (FIG. 3B), sandpaper (FIG. 3C), etc. are reference examples . Further, the opening resistance surface 32 may be attached to both the outer surface of the container body 11 and the engagement piece 31 of the lid 12.
[0019]
【The invention's effect】
As described above, according to the present invention, the reliability of the locking of the lid can be improved without impairing the appearance and strength of the container.
