Description

METHOD OF MANUFACTURING A WATER POCKET BACKGROUND OF THE INVENTION [0001]

More particularly, the present invention relates to a method for manufacturing a water bag, which can solve problems such as evaporation or deterioration of water during circulation by making it possible to distribute the water bag in a dry tissue and to use it in water at the same time as opening the water bag. The present invention provides a method for manufacturing a water bag which can be applied to an extensible wrapping wet tissue.

In general, wet tissue (wet paper) is provided in various forms to moisten the product by adding moisture to the product during the manufacturing process so as to be used for easily wiping hands or face.

The above-mentioned conventional wet tissue is sealed by a hermetically sealed lid of adhesive type or plastic and is made of a material such as PE or PP. Inside the packaging case having a draw-out hole in the upper center, moisture is contained, And a packaging case of various configurations is provided as a means for distributing the wet tissue.

Typical examples are a wet tissue container capable of one-touch opening of Korean Patent Registration No. (B1) 10-0868394 (November 11, 2008.), a wet tissue packing stand of 10-1035418 (2011.05.20.), .

However, in the case of the above-mentioned conventional wet tissue, there is a problem that the tissue is wicked and packed in the packaging case during the manufacturing process, and the moisture is evaporated or the wet tissue is damaged due to the amount of the package in the distribution process.

For the purpose of solving these problems, products which sell dry tissues and allow users to wet the tissues are being marketed, but they are not meeting expectations.

On the other hand, since the wet tissue is circulated or stored in a wet state, it is not completely sterilized and may be partially contaminated with microorganisms such as bacteria. When the wet tissue in which such bacteria are present is used in contact with the soft skin of a baby, there is a problem in that the bacteria can reproduce on the skin and reproduce, which is very hygienic.

Taking this into consideration, we separately use purified water separately from wrapped paper of the dry tissue, and when the wet tissue is needed, water is poured into the dry tissue to be used as a wet tissue. However, there is a problem in that the process of making a dry tissue as a wet tissue is complicated and troublesome, and the general person is reluctant to use it.

1 and 2, a packaging wet tissue 100 according to the present invention includes a packaging case 110, a dry tissue layered body 120, and a water pocket 130.

The packaging case 110 has a case draw-out hole 114 which is hermetically sealed by a closure lid 112 of an adhesive type or plastic construction and formed at the upper center. The packaging case 110 may be formed of a flexible material having two sides opposed to each other in a rectangular box shape by heat treatment or the like, or may be made of a plastic material of a rectangular box-shaped hard material. In this embodiment, the shape and material of the packaging case 110 may be variously changed.

The dry tissue layered product 120 is stacked on the inside of the packaging case 110 in a dry state. For example, the dry tissue layered body 120 may be formed in the following manner. Each of the dry tissues is folded in half with a line connecting the center line thereof so as to face each other symmetrically with respect to each other and the lower side of the upper side of the wet tissue is successively laminated so as to be sandwiched between the upper side and the lower side of the continuous wet tissue . Even if the dry tissue layered body 120 is converted into the wet tissue layered body, the above-described laminated structure remains intact. Accordingly, when the uppermost wet tissue is pulled out, the upper side of the wet tissue in contact with the lower side of the wet tissue is pulled together. As a result, the upper side of the wet tissue protrudes from the case withdrawal hole 114, and can be sequentially taken out from the case withdrawal hole 114 one by one. The dry tissue layered body 120 may be laminated in various manners other than the method of folding in half and laminating as described above.

The water bag 130 includes a sealing bag 132 made of a material such as PE or PP and an adhesive tape 134. The water bag 130 penetrates purified water or sterilized water into the water bag 130, . The sealing bag 132 has one or more cut-out holes or at least one cut-out formed in the water bag draw-out hole formed in the central area and in the peripheral area of the bottom, and inserts purified water or sterilized water. The amount of the purified or sterilized water may be an amount that is metered to suitably convert the dry tissue to a wet tissue. The incision hole or the incisional reduction is formed on the surface that contacts the dry tissue layered body 120, that is, the bottom portion of the water bottle 130. In the present embodiment, the cut-out hole may have a circular shape, an elliptical shape, a polygonal shape, or the like, and the cut-out may be a straight line, a curved line, or the like. In this embodiment, a plurality of cut-out holes are formed in the lower surface of the water bag 130, and an example in which the adhesive tape 134 is taped so that purified water or sterilized water does not flow out through the cut- Respectively.

The adhesive tape 134 is adhered to cover the incision hole or the incisional reduction, and the handle portion 224 is exposed through the case withdrawal hole 114. In this embodiment, the adhesive tape 134 is configured to cover a peripheral portion of the incision hole or a peripheral portion of the incision to block the purified water or sterilized water from being released through the incision hole or the incisional reduction And a handle portion 224 having a large area and a handle portion 224 extending from the cover portion and narrower than the width of the cover portion and having a length that can be exposed to the outside through the case draw-out hole 114.

As the handle portion 224 of the adhesive tape 134 exposed through the case draw-out hole 114 is pulled by the user, water that has been purified or sterilized through the incision hole or the cut- Is provided on the stack 120 to convert the dry tissue stack 120 into a wet tissue stack. After the dry tissue layered body 120 is converted into the wet tissue layered body, the water bag 130 discharging purified water or sterilized water may be disposed as it is or may be extracted to the outside through the case outlet hole 114 .

The water in the water bag 130 penetrates into the dry tissue layered body 120 as the wrapping wet tissue 100 is opened while the wrapped tissue or the wet tissue 100 is opened before the wrapping process or opening of the wrapped wet tissue 100, . Therefore, the bacteria can reproduce after being converted into the wet tissue laminate, but at least the dry tissue state is maintained before being converted into the wet tissue laminate, so that the possession of the bacteria can be removed.

In addition, it can be used as a dry tissue and can be used by being wetted with water at the same time as it is opened, thereby solving the problems such as evaporation or deterioration of water during distribution and prolonging the circulation period.

3A is a front perspective view for explaining a water bag 200 according to an embodiment of the present invention. FIG. 3B is a rear perspective view for explaining the water bag 200 shown in FIG. 3A. 4A is a cross-sectional view taken along line II-II 'shown in FIG. 3A, and FIG. 4B is a cross-sectional view taken along line III-III' shown in FIG. 3A.

3A to 4B, the water bag 200 includes a sealing bag 210 and an adhesive tape 220. [

The sealing bag 210 has a bag body 212, a water bag draw-out hole 214 formed in a central region of the bag body 212, a cut-out hole 216 formed in a peripheral region of the bottom portion, Introduce purified water or sterilized water.

The adhesive tape 220 may include a cover portion 222 covering the incision hole 216 or the incisional reduction to block purified water or sterilized water from being discharged through the incision hole 216 or the incision And a grip portion 224 integrally formed on the cover portion 222 and protruding from the upper surface portion of the sealing bag 210 through the water bag draw-out hole 214. An adhesive layer is formed on the cover part 222 of the adhesive tape 220 to adhere to the peripheral area of the cut-off hole 216 or the peripheral area of the cut-away area to prevent the purified or sterilized water from flowing out. In this embodiment, the adhesive layer is formed on the cover part 222 so as to be easily separated from the sealing bag 210 according to a user's operation.

In the present embodiment, the sealing bag 210 has a rectangular shape, three sides are thermally pressed, and the periphery of the water bag draw-out hole 214 formed in the central area is also thermally compressed.

Accordingly, when the adhesive tape 220 is adhered to the sealing bag 210, the purified water or the sterilized water does not flow out to the outside.

However, when the adhesive tape 220 is removed from the sealing bag 210, that is, when the adhesive tape 220 is peeled off while being adhered while covering the cut-off hole 216 or the incision, The purified water or the sanitized water is discharged through the incision hole 216 or the incision improvement. For example, when the grip portion 224 of the adhesive tape 220 is pulled in the Z-axis direction, the cover portion 222, which is adhered while covering the cut-off hole 216 or the cut-away portion, (216) or away from the incisional detachment, toward the water bag draw-out hole (214). Accordingly, water that has been purified or sterilized through the incision hole 216 or the incision is flowed out in the Z-axis direction.

5A to 5H are plan views illustrating a method of manufacturing a water pocket according to an embodiment of the present invention. In particular, a method of manufacturing the water bag shown in Figs. 3A and 3B is shown.

Referring to FIG. 5A, vinyls having a first width W1 and a predetermined length are prepared. The vinyl may be divided into a first area AR1 corresponding to one half of the first width W1 and a second area AR2 corresponding to the other half of the first width W1. 5A, the right area of the vinyls may be defined as the first area, and the left area of the vinyls may be defined as the second area.

5B, a water bag draw-out hole 214 and a cut-out hole 216 or an incision are formed at the center of one region (i.e., the first region AR1) of the half region of the vinyl, The water bag draw-out hole 214 is formed in the center of the region (i.e., the second area AR2) The water bag draw-out hole 214 formed in the first area AR1 and the water bag draw-out hole 214 formed in the second area AR2 are formed in the first area AR1 and the second area AR2, And is symmetrical with respect to the virtual line (indicated by a dotted line) to be distinguished.

5B, two cut-out holes 216 are formed around the water bag draw-out hole 214, but one or more than three cut-out holes 216 may be formed. In addition, a line-shaped cutout may be formed instead of the water bag draw-out hole 214 having a certain area. The above-mentioned incisional reduction may be a linear shape or a curved shape. In addition, the above-mentioned incline reduction may be a single line or a plurality of lines.

In this embodiment, the shape of the water bag draw-out hole 214 is shown as a circular shape, but it is not limited thereto. That is, the shape of the water bag draw-out hole 214 may be a triangular shape, a square shape, a pentagonal shape, or the like. In this embodiment, the cut-out hole 216 has a rectangular shape, but is not limited thereto. That is, the shape of the incision hole 216 may have various shapes such as a circular shape, a triangular shape, and a pentagonal shape.

5C, an adhesive tape 220 having a cover part and a handle part 224 formed integrally with the cover part is used to cover the incision hole 216 or the incision. The length of the grip portion 224 is preferably larger than a maximum length connecting the cut-off holes 216 formed on both sides of the water bag draw-out hole 214. This is because the grip portion 224 must have a length at which the grip portion 224 is projected outwardly through the water pocket draw-out hole 214 by the user in order to remove the adhesive tape 220.

Referring to FIG. 5D, the vinyl yarn is folded to a half of the first width W1. When the vinyl is folded, the adhesive tape 220 attached to the first region is exposed to the outside by folding the portion corresponding to the second region such that the portion corresponding to the second region is positioned at the back surface of the portion corresponding to the first region.

Referring to FIG. 5E, the right edge region of the vinyl yarn is thermally pressed and adhered along the longitudinal direction of the vinyl yarn. Here, the right edge region of the vinyl yarn subjected to the thermocompression process is defined as the first thermocompression bonding portion THB1. At the same time, the peripheral area of the water bag draw-out hole 214 formed in the first area AR1 and the peripheral area of the water bag draw-out hole 214 formed in the second area AR2 are bonded by thermocompression bonding.

Referring to FIG. 5F, the lower edge region is thermally pressed and adhered to the water bag draw-out hole 214 by a predetermined length downward. Here, the lower edge region of the vinyl yarn subjected to the thermocompression process is defined as the second thermocompression bonding portion THB2. Thus, a vinyl pocket in which the right edge region, the water bag draw-out hole region, and the lower edge region are thermocompression-treated is obtained.

Referring to FIG. 5G, purified water or sterilized water is injected into the plastic pocket.

Referring to FIG. 5H, the upper edge region of the water bag draw-out hole 214 is adhered upward by a predetermined length by thermocompression bonding. Here, the upper edge region of the vinyl yarn subjected to the thermocompression process is defined as the third thermocompression bonding portion THB3. Then, a part of the upper area subjected to the thermocompression process, that is, the third thermocompression bonding part THB3 is cut so as to be contained in the water pocket to finally obtain the water pocket.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. You will understand.

As described above, according to the present invention, by removing the cut-out hole formed at the bottom of the water pocket or the adhesive tape covering the cut-out through the water pocket draw-out hole formed in the central region of the water pocket, The sterilized water is discharged into the dry tissue layered product and converted into a wet tissue, so that the dried tissue state is maintained before the circulation process or opening, thereby solving the problems such as evaporation of moisture in the circulation process as in the prior art. In addition, since water and sanitized water are used, the problem of deterioration of the wet tissue can be solved, and the circulation period can be greatly extended.

In particular, since it is possible to minimize the time to be contaminated by microorganisms such as bacteria, the probability of propagation of bacteria can be greatly reduced even when the baby is used in contact with soft skin, thereby greatly reducing the probability of bacterial infection caused by the wet tissue.
