Description

[Detailed Description of the Invention] The present invention relates to a wet tissue container.

Conventional wet tissue containers on the market consist of a container body and a cap, and the cap consists of a cap base that fits into the container body and a small cap lid that covers the tissue paper outlet of the cap base. ing. In such containers, wet tissue is prevented from drying by tightly engaging the upper end of the container body with the top surface of the cap base and by covering the outlet with the cap lid. In this case, in order to maintain tight engagement between the upper end of the container body and the top surface of the cap base, an annular protrusion is provided that goes around the outer peripheral surface of the upper part of the container body, and when the cap is fitted into the container body, An annular projection that engages with the projection is formed on the inner peripheral surface of the cap base. Alternatively, an annular groove is formed in the container body, and an annular protrusion that fits into the annular groove is formed in the cap base. Due to this structure, in order to remove the cap, it is necessary to disengage the annular protrusions or the annular groove and the annular protrusion, so it is not possible to remove the cap from the container body. Very difficult. However, when the wet tissue is taken out from the outlet, it is torn off along pre-made perforations, and the next wet tissue is separated from the outlet while being slightly pulled out. . However, the end of the next wet tissue may be separated from the perforation without being pulled out. In such a case, the wet tissue falls into the container from the outlet and cannot be pulled out from the outlet. In order to pass the wet tissue through the outlet again, it is necessary to remove the cap from the container body and pass the wet tissue through the outlet. However, as mentioned above, conventional wet tissue containers are inconvenient because it is extremely difficult to remove the cap.

Furthermore, if the engagement between the protrusion on the container body and the protrusion on the cap base is made loose so that the cap can be easily removed, the sealing performance will deteriorate and the wet tissue will dry out.

In conventional wet tissue containers, the seal between the container body and the cap base was achieved only by the tight engagement between the upper end of the container body and the top surface of the cap base, so the sealing performance was poor. It wasn't good.

Furthermore, in conventional wet tissue containers, the internal space of the cap lid surrounding the outlet is extremely small, so if the tip of the wet tissue sticks out far beyond the outlet, the cap lid cannot be properly sealed. It disappears. In addition, in conventional wet tissue containers, the low height and small diameter annular protrusion of the cap lid just fits into the low height and small diameter annular protrusion surrounding the outlet, so the airtightness is not very good. do not have. Furthermore, this structure has the disadvantage that the lid tends to open unless the lid is properly closed after taking out the wet tissue.

The purpose of the present invention is to provide a wet tissue container that eliminates the above-mentioned drawbacks of the conventional wet tissue containers, has good sealing performance, and allows the cap to be attached and removed from the container body very easily. .

The wet tissue container of the present invention consists of a container body and a cap, and the cap consists of a cap base that fits into the container body and a cap lid that covers the tissue paper outlet of the cap base. In the U container, the upper part of the container body has a cylindrical part and a tapered part connected to the cylindrical part, and a cam groove consisting of a part extending in the circumferential direction and an inclined part continuous to the part and extending upward. is provided on the cylindrical portion, and an engagement ring is provided on the top of the cap base, and the engagement ring and the upper end of the container body are tightly fitted, and the inner peripheral surface of the cylindrical portion of the cap base and the cylinder of the container body are closely fitted.

According to the present invention, it is extremely easy to attach and detach the container body and the cap. It also has good sealing properties. That is, the lower end of the cap base is guided to the tapered portion of the container body, so that to attach the cap to the container body, it is only necessary to push the cap from above. Since the cam groove has a circumferentially extending portion, there is no need to align the engaging protrusion on the cap base with the cam groove on the container body when installing the cap.
When removing the cap, since the cam groove and the engaging protrusion are engaged, the cap can be easily removed from the container body by simply rotating the cap base.

Further, according to the present invention, the sealing performance between the container body and the cap is good. In other words, sealing is performed between the container body and the cap base at the engagement ring between the upper end of the container body and the cap base, and between the cylindrical portion of the container body and the cylindrical portion of the cap base, and the sealing is performed by the groove width of the cam groove. There is only a gap. Furthermore, the present invention provides very good sealing between the cap base and the cap lid. That is, sealing is achieved by surface contact between the outer circumferential surface of the annular portion and the inner circumferential surface of the cap lid, and between the inner circumferential surface of the annular portion and the outer circumferential surface of the sealing ring.

Furthermore, according to the present invention, when the cap lid is closed, the space formed between the top surface of the cap base and the top surface of the cap lid is large, so that the tip of the wet tissue can be moved far away from the outlet. Even if it protrudes, the cap lid can be closed properly.
