Abstract

PROBLEM TO BE SOLVED: To improve the locking reliability of a lid without detriment to the external appearance and strength of a paper container. SOLUTION: The paper container 10 for a powdered detergent has folding- back piece 21 which a container main body 11 has held inside an opening edge portion 11F and which are made to be capable of being folded back outwardly of the opening edge portion 11F. Engaging portions 22 provided inside a lid 12 are made to be capable of being locked to the folding-back piece 21 which are folded back, respectively, when the container main body 11 is covered with the lid 12.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a powder detergent paper container.

[0002]

2. Description of the Related Art In detergent containers, paper containers are used for incineration at the time of disposal. Japanese Patent No. 2665903 discloses a paper container in which a lid is hingedly connected to a container body, and a locking tongue piece adhered to an outer surface of an opening edge portion of the container body is peeled off and raised to be provided inside the lid. The locking recess can be locked to the raised locking tongue when the lid is closed. This prevents the lid from rising from the closed position in the opening direction due to the repulsive force of the hinge.

[0003]

The locking tongue that has adhered to the outer surface of the container body is peeled off, and the peeling marks impair the appearance of the container.

[0004] By peeling off the locking tongue, the strength of the container body and the locking tongue is reduced.

The raised locking tongue has a habit of restoring to the outer surface side of the container body bonded before being raised, and this acts as an unlocking habit of coming off from the locking concave portion of the lid. This impairs the reliability of the lock, and tends to cause the detergent to absorb moisture.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the locking of a lid without deteriorating the appearance and strength of a container.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a powder detergent paper container having a lid hingedly connected to a back plate of a container body, wherein a folded piece accommodated inside an opening edge of the container body. Can be folded back to the outside of the opening edge, and the engaging portion provided inside the lid can be locked to the folded-back piece when the lid is closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a powder detergent paper container 10 comprises a container body 11, a lid 12, and a paper seal 13.

The container body 11 is formed by bending a material obtained by laminating a plastic film using only paper or paper as a main material, and a front plate 11A, a back plate 11B, both side plates 11C, 11C, and a bottom plate 11D. Have. The container body 11 includes a front plate 1 forming an opening 11E.
An inner fold flap 11G is provided at each opening edge 11F of the back plate 1A, the back plate 11B, and both side plates 11C, 11C, and the inner fold flap 11G is bonded inward.

The lid 12 is formed by bending a material obtained by laminating a plastic film on a paper only or a paper as a main material, and a front plate 12A and a rear plate 12A.
B, both side plates 12C, 12C and a top plate 12D. Lid 1
2 includes a knob 12E on the front plate 12A and a rear plate 12B
A hinge connecting portion 12F, and both side plates 12
C, 12C is provided with an inwardly folded flap 12G at each lower edge thereof,
The inner folding flap 12G is inwardly bonded. Lid 1
2 is an end near the front plate 12A of both inward folding flaps 12G,
Alternatively, glued flaps 12H are provided on both lower edges of the front plate 12A, and the glued flaps 12H are attached to the inner surface of the front plate 12A.

The paper container 10 includes a back plate 11 of the container body 11.
B is configured by hinge-connecting a hinge connection portion 12F of the lid 12 to B. At this time, the paper container 10 is provided with folded pieces 21 at the opening edges 11F on both sides of the front plate 11A of the container body 11, and the folded pieces 21 are placed inside the opening edges 11F before the sealing paper 13 is opened. After the seal 13 is opened, it can be folded outside the opening edge 11F (FIG. 2). Furthermore,
The paper container 10 includes a recess formed between the glued flap 12H and the back surface of the top plate 12D as an engagement portion 22 inside the front plate 12A of the lid 12. As a result, at the time of closing the lid, FIG.
As shown in the figure, the engaging portion 22 of the lid 12 is locked with a sense of moderation (locking sound) to the folded back piece 21 of the container body 11, and the lid 12 is opened by the repulsive force of the hinge connecting portion 12F. To prevent it from floating.

In the paper container 10, a sealing paper 13 for sealing the opening 11E of the container body 11 is fixed to the outer surface of the front opening 11A, the back plate 11B, and the entire opening edges 11F of the side plates 11C, 11C. It is attached with a width (FIG. 1), so that the powder detergent of the contents can be sealed at the distribution and storage stage.

Therefore, according to the present embodiment, the following operations are provided. (Operation Corresponding to Claim 1) The folded piece 21 provided on the container body 11 is
What was stored inside F is simply turned back to the outside and used. Therefore, when the folded piece 21 is used, the appearance of the container 10 is not impaired, and the strength of the container body 11 and the folded piece 21 are not reduced.

The folded back piece 21 has a habit of restoring the inside of the container body 11 stored before being folded back, and this acts as a locking promoting habit of hitting the engaging portion 22 of the lid 12. The lock of No. 12 was improved to prevent the detergent from absorbing moisture.

(Operation According to Claim 2) When the paper seal 13 is sealed, the folded piece 21
Is housed inside the opening edge 11F, so that even when the paper seal 13 is attached to the opening edge 11F in a range of a fixed width from the upper end surface to the outer surface, the folded piece 21 is not opened when the paper seal 13 is opened. There is no peeling of the surface layer. Therefore, while ensuring the sealing by the paper seal 13, the folded piece 21 is not fragile.

[0016]

As described above, according to the present invention, the locking reliability of the lid can be improved without impairing the appearance and strength of the container.
