DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a wet tissue package configured to store a wet tissue inside a storage body such as a bag or a container, and to open a lid to take out the internal wet tissue one by one when used.

[0002]

[Prior art]

In recent years, wet tissue has been actively used for business or home use, and its consumption has been expanding year by year. Wet tissue is made by impregnating a fibrous sheet such as a nonwoven fabric with an impregnating agent such as a drug or cosmetic.
It is used for wiping the baby's ass, removing dirt from hands, and disinfecting.

[0003] There are two types of packaging of wet tissues: a structure in which wet tissue is stored in a bag, and a structure in which wet tissue is stored in a container. For example, a bag housing structure is disclosed in Japanese Patent Publication No. 2-30948, and a container housing structure is disclosed in JP-A-6-263174.

In general, a wet tissue package having a bag storage structure stores a wet tissue inside a bag formed using an airtight film, and a take-out opening for taking out the wet tissue is provided on the upper surface of the bag. In order to prevent the impregnating agent impregnated in the wet tissue from volatilizing, a cover for covering the outlet is provided on the upper surface of the bag body.

On the other hand, a wet tissue package having a container storage structure is usually configured to be refillable. Therefore, a container for storing the wet tissue includes a container body and a container lid, and a take-out opening is provided in the container lid. In addition, a lid for covering the outlet is provided on the container lid.

[0006] In a wet tissue package, smooth removal of wet tissue is a very important technical problem. The inventor has previously proposed a wet tissue package having a pop-up structure (Japanese Patent Application Laid-Open No. 8-31897), but has made various studies to take out the wet tissue in this pop-up structure more smoothly.

In order to form the pop-up structure, it is necessary to fold each leaf of the wet tissue to an appropriate width and to stack the wet tissues so that the folded portions are entangled with each other to form a wet tissue laminate. Along with
It is necessary to form a narrow portion with a narrow passage width in a part of the wet tissue outlet.

According to the pop-up structure, when one wet tissue is taken out, the lower end of the wet tissue is
Since the upper end of the second wet tissue is entangled with the second wet tissue, the second wet tissue is also pulled upward, and the upper end passes through the outlet. Due to the resistance when passing through the width portion, the wet tissue ends are disentangled from each other, and the first wet tissue and the second wet tissue are separated. As described above, since the second wet tissue is moved upward, the upper end portion of the wet tissue is protruded upward from the takeout opening. Easy to take out.

[0009]

[Problems to be solved by the invention]

However, since the wet tissue is impregnated with the liquid impregnating agent, there is a problem that the wet tissue adheres to each other due to the wetting of the impregnating agent. It may be difficult. As a result, when one wet tissue is taken out, the first and second wet tissues are taken out without being separated,
In severe cases, three or more wet tissues may be continuously taken out. In such a case, the wet tissue must be forcibly separated by hand.

In an unopened wet tissue package, a sealing seal is previously attached to a take-out port to prevent volatilization of the impregnating agent. When using this unopened wet tissue package for the first time, the sealing sticker attached to the outlet must be peeled off, and the first wet tissue must be picked out from the outlet with a finger. Is provided with a hole large enough to allow the user to pick up the wet tissue with his finger. For this reason, the entire passage width of the outlet cannot be configured to be narrow, and there is naturally a limit to completely separating the wet tissues from each other due to the resistance when the wet tissue passes through the outlet. There is a case where a problem that the tissues are not separated from each other occurs. In addition, even when wet tissues are separated from each other, it takes a long time to complete the separation, and therefore,
There is a case where a problem that the protrusion length of the second wet tissue becomes unnecessarily long may occur.

[0011]

[Object of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wet tissue package that allows smooth and complete separation between wet tissues when the wet tissue is taken out.

[0012]

[Means for Solving the Problems]

The present invention is a wet tissue package in which a wet tissue laminate is housed inside a housing. The container has a take-out opening formed therein, and the take-out opening is formed in the take-out opening. The storage body is provided with a lid for opening and closing the outlet. A projection is provided on the surface of the outlet forming portion on the wet tissue storage side.

The projection is composed of a number of point-like projections. These many point-like projections are provided in a single or multiple ring shape along the periphery of the outlet in the outlet forming part.

In the present invention, since the projection is provided on the surface of the take-out opening forming portion provided in the storage body on the side of the wet tissue storage side, when the first wet tissue is taken out, the friction between the wet tissue and the protrusion is reduced by friction. Occurs, so that the entanglement between the ends of the first wet tissue and the second wet tissue is securely removed,
Separation of both is performed smoothly.

As a result, the pop-up of the second wet tissue is always performed reliably at a predetermined position.

Therefore, according to the present invention, the projecting length of the second wet tissue is unnecessarily long, or the wet tissues are not properly separated from each other and a plurality of the wet tissues are connected and pulled out. There is no fear.
