Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated wet tissue used for wiping off dirt and the like.

[0002]

2. Description of the Related Art Conventionally, it is well known that a non-woven tissue paper is impregnated with a chemical liquid and wet tissues are alternately folded and stored in a container so that the tissues can be separated and taken out one by one.

[0003]

The container containing the wet tissue is one of the folded wet tissues if the outlet can be made relatively small.
It is easy to separate and take out one by one. However, if the size of the take-out port cannot be made small, it becomes difficult to reliably separate and take out the wet tissues that are strongly adhered to each other by getting wet. For example, when the wet tissue is to wipe the baby's buttocks and is used by refilling it into a container, make the container outlet relatively large so that the mother can easily carry out the refilling work. Sometimes. The wet tissue stored in the container must be inserted through the outlet from the inside of the container to the outside of the first tip to be taken out.
The larger the mouth, the easier the insertion. On the other hand, in such a container, it becomes difficult to separate the wet tissues one by one at the outlet, so that the next one to be taken out may be taken out. Sometimes you can look into it.

Therefore, the present invention has an object to make it possible to easily separate a plurality of wet tissues alternately folded one by one.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a wet tissue in which a tissue paper is impregnated with a chemical solution, and the wet tissues are alternately folded so that each of them can be taken out from a required container one by one. It is based on a tissue stack.

On the premise, the present invention is characterized in that the wet tissue is made of the hydrophobic fiber 1.
An intermediate layer consisting of 0 to 50% by weight of hydrophilic fibers 0 to 50% by weight, upper and lower layers, hydrophobic fibers of 0 to 20% by weight and hydrophilic fibers of 100 to 80% by weight, and interposed between the upper and lower layers. It consists of and.

[0007]

The details of the wet tissue laminate according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, (A) is a perspective view of the wet tissue refill container 1, and (B) is a schematic partial side view of the wet tissue 2 stored in the container 1. The container 1 includes a container body 3 and an outer lid 4. The outer lid 4 is attachable to and detachable from the main body 3, and has a relatively large tissue take-out opening 5 in the center that allows the insertion of two fingers. The take-out opening 5 is formed integrally with the outer lid 4. It can be opened and closed with the inner lid 6. The wet tissues 2 are housed as a laminated body 7 in which each sheet is alternately folded in a Z shape, and the tip of the uppermost wet tissue 2 is seen through the outlet 5. That wet tissue 2
When the tip is lightly lifted, it separates from the one to be taken out next and goes out of the container 1, while the tip of the one to be taken next is seen from the take-out port 5.

A wet tissue 2 shown in a partial cross-sectional view in FIG. 2 is obtained by impregnating a non-woven tissue paper with a required chemical liquid, and the tissue paper is composed of upper and lower layers 1.
1 and 12 and an intermediate layer 13 interposed between these layers 11 and 12. Upper and lower layers 11, 12
Is 100 to 50% by weight of hydrophobic fiber and 0 to 5 of hydrophilic fiber.
0% by weight, and the intermediate layer 13 is composed of hydrophobic fibers 0-2.
It comprises 0% by weight and 100-80% by weight of hydrophilic fibers.
Each layer 11, 12, 13 has a basis weight of 5 to 50 g / m ² . The fibers are mechanically intertwined with each other or welded to each other in each layer and between the layers, or maintain the form of the non-woven fabric by the entanglement and the welding. Especially when a wet tissue having a good feel is required, it is preferable that the fibers are mechanically entangled. As the hydrophobic fibers, thermoplastic synthetic fibers such as polyethylene, polypropylene, nylon, polyester and the like and composite fibers thereof can be used. As the hydrophilic fibers, rayon fibers, plant fibers such as pulp and cotton, hydrophilic fibers and the like can be used. Chemically treated thermoplastic synthetic fibers and the like can be used.

The composition of the chemical solution to be impregnated into the nonwoven fabric can be determined according to the application of the wet tissue.
For example, when the purpose is to wipe the baby's buttocks, a mixture of 10% by weight of propylene glycol and 90% by weight of water, or a mixture of 7% by weight of propylene glycol, 0.3% by weight of parapen and 92.7% by weight of water. The tissue paper may be impregnated with. The appropriate impregnation amount at that time is 150 to 300% of the dry weight of the tissue paper.

Wet tissue 2 constructed in this manner
Then, the impregnated chemical liquid is mainly retained in the intermediate layer 13 having a strong hydrophilic property, and the upper and lower layers 11 and 12 containing a large amount of the hydrophobic fibers.
However, the water content is relatively low. As a result, the tissues 2 overlapping each other as the stacked body 7 are not strongly adhered to each other via the chemical liquid, and when taken out from the container 1, the tissues 2 are easily separated one by one, and the next one to be taken out is unusable. There is no need to look into the outlet 5. Further, in the wet tissue 2, when pressure is applied during use, the chemical liquid exudes from the intermediate layer 13 and can appropriately wet the surface to be wiped.

Although not shown, if the wet tissue 2 is embossed so that a large number of uneven portions are present on the upper and lower (front and back) surfaces, the wiping effect is improved and the wet tissue 2 is laminated. The contact area between the two is smaller than that in the case where the processing is not applied, and thus the separation is easier.

[0013]

EFFECT OF THE INVENTION Since the wet tissue laminate according to the present invention is mainly composed of hydrophobic fibers on the front and back surfaces of each wet tissue, overlapping wet tissues do not strongly adhere to each other via the impregnating chemical solution, The wet tissues can be easily separated one by one.
