1 is a flow chart showing a method of manufacturing a wet tissue usable as a disposable bag according to a preferred embodiment of the present invention, Figure 2 is a perspective view of a tissue manufactured by the method of manufacturing a wet tissue usable as a disposable bag according to a preferred embodiment of the present invention .

As shown in Figure 1, the method of manufacturing a wet tissue usable as a disposable bag according to a preferred embodiment of the present invention is largely a winding step (S10), a first bonding step (S20), a cutting step (S30), a second bonding step (S40), packaging step (S50), immersion step (S60) and sealing step (S70).

Specifically, the winding step (S10) is a step of unwinding the nonwoven fabric wound in a roll form and winding it in a cylindrical shape so that both ends in the width direction of the nonwoven fabric come into contact with each other, which will be described later through the winding step (S10). After using the tissue 10 inside the bag-shaped tissue 10 for the purpose of wiping contaminants such as dust or foreign matter, the non-woven fabric has a space for holding the contaminants or trash. Shape can be machined.

The nonwoven fabric wound in the winding step (S10) is joined at both ends in the width direction so as to maintain a cylindrical shape to form a side-end joint 12 (S20).

Here, bonding refers to a method of applying heat and pressure to the nonwoven fabric through thermal bonding, high frequency bonding, ultrasonic bonding, etc. to adhere to each other, and is distinguished from the bonding of the sewing method, preferably productivity and cost competitiveness, nonwoven material, etc. The ultrasonic bonding method may be selected in consideration of the bonding characteristics of the synthetic resin material, but is not limited thereto.

The cylindrical shape is maintained through the first bonding step (S20), and thereafter, the tissue 10 is formed by cutting the nonwoven fabric into a predetermined length (S30).

At this time, since the tissue 10 is in a state where both the upper and lower ends are open, the tissue 10 has the shape of an envelope with only the upper end as shown in FIG. 2 through the second bonding step (S40). .

Specifically, in the second bonding step (S40), the bottom bonding portion 14 is formed by bonding an open portion to the bottom of the tissue 10 using one of thermal bonding, high-frequency bonding, or ultrasonic bonding, Through this, the tissue 10 may have an envelope shape.

A plurality of the tissues 10 formed in the shape of an envelope through the second bonding step (S40) are stacked alternately in the vertical direction, and one side is opened to be introduced into a packaging pack (not shown) in which an inlet is formed, thereby forming a normal wet tissue. It is packed with (S50).

At this time, the packaging pack (not shown) is formed of a paper material or a vinyl material coated with a synthetic resin material such as PE (Poly Ethylene), PET (Poly Ethylene), or LLDPE (Linear Low Density Poly Ethylene), which will be described later. It has a waterproof effect to prevent leakage or evaporation to the outside.

Thereafter, an undiluted wet tissue solution is injected into the packaging pack (not shown) through the opening of the opened packaging pack (not shown) to immerse the tissue (S60).

In general, wet tissues are usually gripped by the user to wipe the contaminated target surface, so not only must have a high moisture content and excellent cleaning power, but also have excellent safety and antibacterial properties for the skin. Accordingly, the wet tissue stock solution may contain purified water, a surfactant, a sterilizing and disinfecting agent, a skin moisturizing agent, an anti-fungal agent, an antibacterial agent, a preservative, and other additives.

When the wet tissue stock solution is sufficiently wetted in the tissue 10 in the immersion step (S60), the inlet of the packaging pack (not shown) is adhesively sealed, and opening and closing is performed at the outlet formed in the center of the top surface of the packaging pack (not shown). Attach a possible cover (not shown) (S70).

The cover (not shown) is sealed by covering the outlet, thereby preventing the moisture contained in the tissue 10 from evaporating and losing its function as a wet tissue, and dust, etc., through the outlet, the packaging pack (not shown) Si) It is possible to prevent contamination of the tissue, the wet tissue stock solution, etc. by flowing into the inside.

Specifically, the cover (not shown) is formed of a synthetic resin material and is attached to the upper surface around the outlet so that the hinge can be opened and closed. When the user wants to use a wet tissue, the cover (not shown) is hinged to open in one direction. The tissue 10 can be used by pulling out as many sheets as necessary from the outlet. In addition, a detachable sticker (not shown) may be additionally attached to the outlet to increase the sealing force of the packaging pack (not shown).

3 is a perspective view of a tissue manufactured by a method of manufacturing a wet tissue usable as a disposable bag according to another embodiment of the present invention, and FIG. 4 is an operational state diagram showing a state in which the tissue shown in FIG. 3 is used as a disposable bag.

As shown in FIGS. 3 to 4, after the cutting step (S30) or the second bonding step (S40), a part of the upper end of the tissue 10 is additionally included, including a cutting step (not shown). It can be cut to length to form the gripping portion 18.

Specifically, by cutting the center of the upper end of the tissue 10 to a predetermined length to form the gripping part 18 that can be inserted by a finger, after containing contaminants or garbage in the tissue 10, the gripping part It is to be easily moved to the place where the waste can be disposed, that is, the place where the trash can is disposed by pinching and holding a finger in (18).

At this time, when the tissue 10 is used for cleaning contaminants, the gripping part 18 is preferably cut in a straight line having a minimum length to prevent tearing caused by irregularities on the surface of the object. However, it is not limited thereto, and may be processed into various shapes such as circular or oval.

Although the embodiments of the present invention have been described with reference to the above and the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can implement the present invention in other specific forms without changing the technical spirit or essential features. You can understand that there is. Therefore, it is to be understood that the embodiments described above are illustrative and non-limiting in all respects.
