TECHNICAL FIELD 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. Japanese Patent No. 2656903 discloses a paper container in which a lid is hingedly connected to a container main body, and a locking tongue piece adhered to an outer surface of an opening edge of the container main 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]
[Problems to be solved by the invention]
{Circle around (1)} The locking tongue pieces adhered to the outer surface of the container body are peeled off, and the peeling marks impair the appearance of the container.
[0004]
{Circle around (2)} By peeling off the locking tongue, the strength of the container body and the locking tongue is reduced.
[0005]
{Circle around (3)} The raised tongue piece has a habit of restoring to the outer surface side of the container main body which was adhered before being raised, and this acts as an unlocking habit of coming off from the locking concave portion of the lid. The lock reliability is impaired, and the detergent tends to absorb moisture.
[0006]
An object of the present invention is to improve the reliability of locking of a lid without impairing the appearance and strength of a container.
[0007]
[Means for Solving the Problems]
The present invention, the cover on the back plate of the container body Ri name and hinged, the paper seal for sealing the opening of the container body in a powder detergent cartons ing by sticking to the outer surface of the opening edge A folded piece that is housed inside the opening edge of the container body before opening the paper seal can be folded outside the opening edge after opening , and the engaging part provided inside is closed. Sometimes, it can be locked to the folded piece.

BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIG. 1, the powder detergent paper container 10 includes a container body 11, a lid 12, and a paper seal 13.
[0009]
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 has a front plate 11A, a back plate 11B, both side plates 11C, 11C, and a bottom plate 11D. The container body 11 is provided with an inwardly folded flap 11G at each of the opening edges 11F of the front plate 11A, the back plate 11B, and both side plates 11C and 11C forming the opening 11E, and the inwardly folded flap 11G is inwardly bonded. .
[0010]
The lid 12 is formed by bending a material obtained by laminating a plastic film using only paper or paper as a main material, and has a front plate 12A, a rear plate 12B, both side plates 12C, 12C, and a top plate 12D. The lid 12 includes a knob 12E on the front plate 12A, a hinge connection portion 12F on the rear plate 12B, and an inwardly folded flap 12G on each lower edge of both side plates 12C, 12C. It is folded inside. The lid 12 is provided with glued flaps 12H on both ends of the inwardly folded flaps 12G near the front plate 12A or 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. It is.
[0011]
The paper container 10 is configured by hinge-joining a hinge joint 12F of a lid 12 to a back plate 11B of a container body 11. 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 sealing paper 13 is opened, it can be folded outside the opening edge 11F (FIG. 2). Further, 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. Thereby, at the time of closing the lid, as shown in FIG. 3, the engaging portion 22 of the lid 12 is locked to the folded piece 21 of the container body 11 with a sense of moderation (locking sound), and the lid 12 is hinged. It prevents floating in the opening direction due to the repulsive force of the connecting portion 12F.
[0012]
In the paper container 10, a paper seal 13 for sealing the opening 11E of the container body 11 is attached with a fixed width to the outer surface of the front opening 11A, the back plate 11B, and the entire opening edges 11F of the side plates 11C and 11C. (FIG. 1) so that the powder detergent of the contents can be sealed at the distribution storage stage.
[0013]
Therefore, according to the present embodiment, the following operations are provided.
(Action corresponding to claim 1)
{Circle around (1)} The folded piece 21 provided on the container main body 11 is one which is simply folded back to the outside, which is stored inside the opening edge 11F. 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.
[0014]
{Circle around (2)} 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. Twelve locks were improved in reliability to prevent the detergent from absorbing moisture.
[0015]
(Action corresponding to claim 2)
{Circle over (3)} When the paper seal 13 is sealed, the folded piece 21 is housed inside the opening edge 11F, so that the paper sealing 13 is within a certain width from the upper end surface of the opening edge 11F to the outer surface. When the seal 13 is opened, the surface layer of the folded piece 21 does not peel off at all. Accordingly, the folded piece 21 is not fragile while ensuring the sealing by the paper seal 13.
[0016]
【The invention's effect】
As described above, according to the present invention, it is possible to improve the reliability of locking of the lid without impairing the appearance and strength of the container.
