Description

Wet paper towel sealing structure

The present invention relates to a sealing structure, and more particularly to a sealing structure for a wet tissue.

The commonly used wet wipes prevent the moisture in the bag from escaping after opening, so that the wet wipes become dry and dry. Usually, an adhesive label is attached to the opening of the bag, and the adhesive label is torn when the wet tissue is taken. After opening, the adhesive label is pasted back to the opening, but after the adhesive label is peeled off and pasted many times, the adhesive label will lose the stickiness, and the label will also be contaminated by dust during use. The label does not fit snugly on the bag, thus losing the seal.

For example, Taiwan Patent Publication No. 535555 "Integrally formed wet wipes cover" has a cover attached to the opening of the bag body. This method can avoid the disadvantage that the adhesive label loses the adhesiveness and loses the sealing effect, but when the user When the cover is opened and the wet tissue is taken, the opening of the bag directly contacts the outside air, so that the moisture of the wet tissue is quickly evaporated when the cover is opened, causing the problem of early drying.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a sealing structure for a wet tissue, which can maintain a good sealing effect after opening the wet tissue to maintain the wettability of the wet tissue.

In order to achieve the above object, the sealing structure of the wet tissue provided by the present invention comprises a cover assembly, an upper positioning member, a lower positioning member and a case; wherein the cover assembly has a base and an upper cover, the base An annular sleeve having a plurality of partitions on the inner wall surface ring, one end of each of the partitions extending toward the center of the annular sleeve to form an opening for holding the wet tissue head, the ring The outer wall of the sleeve has a latching portion, and the base is connected with the upper cover with a flexible connecting piece so that the upper cover can be covered or detached from the base.

The upper positioning member has a first plate body and a through hole extending through the plate body. The first plate body extends downwardly from the through hole to have a first ring portion, and the through hole and the first ring portion Forming an abutting surface; the lower positioning member has a second plate body and a through hole penetrating the plate body, and the second plate body extends upward from the periphery of the through hole with a second ring portion, the second ring portion The wall has a stop portion, the bottom of the second plate body is attached to a surface of the bag body, the lower member and the bag system are accommodated inside the box body, and the second ring portion of the lower positioning member can be inside and outside Inserting the box body to sleeve the first ring portion, the abutting surface of the upper positioning member is resisted to the upper end of the second ring portion, and the latching portion of the base passes through the upper positioning member The through hole enters the inner wall of the second ring portion and is latched on the stopping portion. The combination of the upper cover assembly, the upper positioning member and the lower member achieves the sealing effect of the wet tissue.

The detailed construction, features, assembly or use of the sealing structure of the wet tissue provided by the present invention will be described in the detailed description of the subsequent embodiments.
