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 floating from the closed position in the opening direction due to the repulsive force of the hinge, and makes it possible to avoid the moisture absorption and solidification of the detergent.

[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 is a powder detergent paper container having a lid hinged to a back plate of the container body, wherein an engaging end face is provided on the outer surface of a side wall of the container body, and The engagement piece turned inward can be locked to the engagement end face of the container body 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. As shown in FIG. 2, the container body 11 includes a front plate 11A, a rear plate 11B, and both side plates 11C that form an opening 11E.
An inner fold flap 11G is provided at each opening edge 11F of 11C, and the inner fold flap 11G is inwardly bonded.

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 is provided with a sticking piece 12E to be attached to the front plate 11A of the container body 11 at the center of the lower edge of the front plate 12A (available as a knob when the lid is opened), and a hinge connecting portion 12F on the rear plate 12B.
And glued flaps 12G connected to both side plates 12C, 12C 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 formed by notching the hole 21 in the side plate 12C of the lid 12 when the lid is closed on both side plates 11C, 11C (side walls) of the container body 11, and the upper end face of the hole 21 is closed. The engagement end face 21A of the invention is used. The hole 21
Is closed by the inner folding flap 11G, and the paper container 10 is closed.
Do not compromise the sealing of the On the other hand, both side plates 12C, 1
At the lower edge portion of the 2C corresponding to the hole 21, an engagement piece 22 turned inside the lid 12 is provided. Thereby, the lid 12
At the time of re-closing after peeling off the sticking piece 12E from the front plate 11A of the container main body 11, the engaging piece 22 of the lid 12 is brought into contact with the engaging end face 21A of the hole 21 of the container main body 11 as shown in FIG. It is locked with a feeling (locking sound), and the lid 12 is
Prevents floating in the opening direction due to the repulsive force of 2F,
The powder detergent of the contents is prevented from being absorbed and solidified.

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. (Effect Corresponding to Claim 1) The engagement end face 21A provided on the container body 11 is
The side plate 11C is provided in advance with a notch-formed hole 21 and the engagement piece 22 provided on the lid 12 can also be provided in advance on the lower edge of the side plate 12C of the lid 12. Therefore, the engagement end face 21A,
The use of the engagement piece 22 does not impair the appearance of the paper container 10 and does not cause a decrease in the strength of the container body 11 and the lid 12 (including the engagement piece 22).

The engagement piece 22 is used by being folded back inside the lid 12, but has a restoring behavior that expands outward before being folded back, and this is a locking promotion that comes into deep contact with the engagement end face 21 A of the container body 11. Acting as a habit, the locking of the lid 12 was improved, and the detergent was prevented from absorbing moisture.

The sealing paper 13 is an outer surface following the upper end surface of the opening edge 11F of the container body 11, and can be stuck in a fixed width range separated from the engaging end surface 21A. Engagement end face 21A when paper 13 is opened
There is no damage due to peeling off of the surface layer around. Accordingly, the engagement end face 21A is not fragile while ensuring the sealing by the paper seal 13.

The paper container 100 shown in FIG. 3 and FIG.
Is different from the paper container 10 in that the front plate 11 of the container body 11
A (side wall) is provided with a hole 31 and an engagement end face 31A, and the sticking piece 12E provided on the front plate 12A of the lid 12 is folded inward to be used as the engaging piece 32 of the present invention. Hole 3
1 is closed by the inner folding flap 11G.

Accordingly, in the paper container 100, as shown in FIG.
Is locked with a sense of moderation (locking sound) to the engagement end face 31A of
The lid 12 is prevented from floating in the opening direction due to the repulsive force of the hinge joint 12F, and the powder detergent of the content is prevented from being absorbed and solidified. And the above-mentioned ~ which paper container 10 plays
It has the same function as.

[0018]

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.
