Description

Cover structure for wet tissue packaging container with sealing function }

The present invention relates to a cover structure for a wet tissue packaging container having an airtight maintenance function, and more particularly, by providing an elastic sealing ring in the cover structure to open or close an outlet of a packaging container containing wet tissues therein, opening and closing for sealing It relates to a cover structure for a wet tissue packaging container having an airtight maintenance function that prevents moisture from evaporating to the outside by improving airtightness by elasticity by pressing the elastic sealing ring in the process of fastening the cover.

In general, a wet tissue is a type of tissue paper, and it refers to a damp tissue that contains moisture in the product during the manufacturing process, and is mainly used for wiping hands or face, removing stains, and wiping dust.

These wet tissues are formed of various materials, and synthetic fibers, viscose fibers, cotton fibers, cellulose fibers, natural vegetable fibers, etc. are made into a tissue by thin tissue, and water is added thereto and sterilized to manufacture. Wet wipes can wipe the user's hands and face regardless of location, and recently, they are widely used to wipe the skin of infants and young children when changing diapers.

On the other hand, wet wipes are generally stored in a container such as a plastic pack to prevent moisture evaporation and to be easily carried and sold. Such a wet tissue container includes a container in which a plurality of wet tissues are stored in a folded state, and a container is formed with a draw-out hole through which the wet tissues are drawn out; and an adhesive sheet attached to the upper surface of the container to open and close the withdrawal hole.

However, when the adhesive sheet is repeatedly opened and closed, there is a problem in that the pull-out hole cannot be properly closed as the adhesive strength is weakened, and there is a disadvantage in that it is inconvenient to pull the adhesive sheet to open it. Accordingly, in recent years, a product having a lid attached to the upper portion of the container and having a lid for separately opening and closing one side of the upper surface on which the withdrawal hole is formed has been developed and used.

However, in the conventional cover provided with the cover, the wet tissue contained in the plastic pack can be withdrawn by allowing the cover to be detachably fastened from the cover. Moisture leaks to the outside and the wet tissue becomes dry.

The above-mentioned invention refers to the background of the technical field to which the present invention pertains, and does not mean the prior art.
