4 and 5 are use state diagrams showing a state in which the disposable pull-on diaper is disposable using the adhesive tape according to the present invention.

Hereinafter, an adhesive tape for disposing of diapers according to the present invention will be described with reference to the drawings, but it is to be understood that those skilled in the art will readily appreciate that the present invention can be easily carried out by those skilled in the art , And this does not mean that the technical idea and scope of the present invention are limited.

As shown in FIG. 1, the adhesive tape for disposing diapers according to the present invention is an adhesive tape (T) laminated in three layers for wrapping and disposing a used disposable diaper, An upper portion of the adhesive film layer 10 is bonded to one end of the adhesive film layer 10 and an upper portion of the adhesive film layer 20 is formed thereon. A hot melt adhesive 40 is applied to the lower surfaces of the adhesive film layer 10, the elongate film layer 20 and the fixing film layer 30, 21, and 31 on the upper surfaces of the adhesive film layer 10, the elongate film layer 20, and the fixation film layer 30, respectively.

The adhesive film layer 10, the elongation film layer 20 and the fixing film layer 30 may be formed of one or more kinds selected from polyethylene, polypropylene, and EVA (Ethylene Vinyl Acetate Copolymer) Although it is preferable that it is made of a polyolefin resin, it is advantageous that polyvinyl chloride (PVC) can be regenerated by a plastic film widely used in the past. However, the additive phthalate (DEHP) It has the disadvantage of causing environmental hormones and carcinogens. Polyolefins, however, are not only recyclable but are also called eco-friendly materials because they do not have toxic components in the human body.

Since the polyolefin-based resin can increase the flexibility of the film to a considerable level by reducing the crystallinity and the density during the polymerization process, the elongation of the produced film can be adjusted according to the required performance, Is manufactured to have a thickness of 20 to 60 占 퐉 and a percentage of elongation of 500 to 1000%, thereby wiping the diaper used by the excellent stretching force of the stretch film layer 20 upon discarding the used diaper, It is possible to exhibit an effect of not only hygienic but also significantly reducing the volume of waste.

On the other hand, the adhesive film layer 10 and the fixing film layer 30 are formed to have a thickness of about twice the thickness of the elongate film layer 20, that is, a thickness of 50 to 100 탆, And the density is increased to adjust the physical properties to have a percentage of elongation of about 50% or less (20 to 50%), whereby the adhesive film layer 10 is formed by the action of the hot- The fixing film layer 30 firmly fixed to one side of the outer surface of the diaper and connected to the distal end of the stretch film layer 20 is adhered to a certain portion of the used diaper with sufficient strength by the same action as that of the pressure- And is adhered to a waste treatment form.

The adhesive film layer 10, the elongation film layer 20, and the fixing film layer 30 are connected to each other by thermal fusion to form a three-layer structure in order to exhibit the above functions. This is because the polyolefin resin film The hot melt adhesive 40 is applied to the lower surfaces of the adhesive film layer 10, the elongate film layer 20 and the fixing film layer 30 and the elongation of the adhesive film layer 10 and the elongation The upper surface of the fixing film layer 30 of the film layer 20 may be treated with the releasing agents 11, 21 and 31.

The releasing agent (non-adhesive agent) is not particularly limited to a specific kind as long as it is harmless to human body such as silicone, fluorine compound, PVA (polyvinyl alcohol) The releasing agents 11 and 21 of the fixing film layer 30 appropriately lower the peel strength at the time of using the adhesive tape T to improve the convenience of use and the releasing agent 31 on the upper surface of the fixing film layer 30, and improves the workability by appropriately maintaining the unwind strength of the adhesive tape T made of roll type.

The hot-melt adhesive 40 applied to the lower surfaces of the adhesive film layer 10, the elongate film layer 20 and the fixing film layer 30 may be any one selected from a styrene-butadiene rubber type or an acrylic type, The adhesive strength of the hot-melt adhesive 40 is preferably about 8 ± 2 g / m 2, and the adhesive strength of the hot-melt adhesive 40 is preferably about 10 to 30 μm, (adhesive strength and peel strength). The hot-melt adhesive 40 is water-soluble and does not harm the human body at all.

On the other hand, it is preferable to apply a corona treatment to one side of the film layers 10, 20 and 30 in order to improve the adhesion with the pressure sensitive adhesive 40. Generally, the corona treatment is performed on a substrate of a polyolefin film, paper, As a technique for modifying the surface of a substrate by irradiating a corona discharge, a corona discharge is generated by applying a high-frequency high-voltage power supplied by a high-frequency power source to the discharge electrode-treatment roll, and the substrate is passed under this corona discharge.

In the corona discharge treatment, the surface tension is lowered due to the synergistic effect of the physical surface modification of the discharge itself and the chemical surface modification by the generation of the polar functional group, and the wettability can be improved. For example, in the case of the plastic film, Electrons and ions of high energy are collided to generate radicals and ions on the surface of the plastic and ozone, oxygen, nitrogen, moisture and the like around them are reacted to introduce polar functional groups such as a carbonyl group, a carboxyl group, a hydroxyl group and a cyano group Causes chemical surface modification. The film substrate subjected to corona treatment as described above is chemically and physically surface-modified to improve the hydrophilicity, adhesiveness, coating and deposition characteristics, and the effect of removing oil present on the surface. Thus, Thereby enhancing the thickness uniformity and surface smoothness of the applied pressure-sensitive adhesive.

In addition, since the hot-melt adhesive 40 applied to the lower surface of the elongate film layer 20 only functions to maintain the elongated state in three layers, as shown in FIG. 2, The formation of the hot melt adhesive 40 in the form of a stripe may reduce the peel strength of the film and the material cost of the hot melt adhesive 40 and increase the elongation of the stretch film layer 20 the hot melt adhesive 40 preferably forms stripes in a direction orthogonal to the direction in which the film is stretched.

As shown in FIG. 3, in the present invention, when disposing a used diaper, the adhesive tape T attached to one side of the diaper is wrapped in a straight line, and the adhesive tape T is fastened The end of the film layer 30 is more convenient to use by forming the handle portion 32 to which the hot-melt adhesive 40 is not applied in order to facilitate peeling.

4 to 5 are explanatory diagrams showing a state in which the disposable pull-on diaper is discarded using the adhesive tape according to the present invention. The diaper D is held in place by holding the grip portion 32 of the adhesive tape T after the diaper D is used The stretched film layer 20 and the fixing film layer 30 are peeled off from the adhesive film layer 10 fixed to one side of the outer surface of the diaper D, Next, the used diaper is folded in a waste disposal form so as to prevent leakage of secretion, and is sealed using the elasticity of the elongate film layer 20 stretched 5 to 10 times longer than the original length, and the fixing film layer 30 As shown in Fig.

As described above, the present invention is characterized in that the adhesive tape 10, the stretched film layer 20, and the fixing film layer 30 are bonded to one side of one side of the disposable diaper D to form an adhesive tape laminated in three layers The disposal of the used diaper is tightly sealed by the stretching force 20 of the stretched film layer and the binding force 30 of the fixing film layer so that the diaper is tightly sealed so that it is sanitary as well as the volume of the waste can be reduced will be.

The adhesive tape for disposing diapers as described above is used for adhering to a back sheet of a body part of a diaper or by providing an adhesive tape as a separate product, thereby firmly fixing the disposable diaper used in a waste treatment form, May be used to fold and sanitize waste of various disposable products such as water, personal hygiene materials or clothing, bags, sporting goods, protective clothing, bed cover or surgical gown.
