[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glove having antibacterial properties, excellent in heat insulating property, heat sealing processability, waterproof property, and water resistant property, and more particularly to a simple glove mainly used for handling frozen food.

[0002]

[Prior art]

 A simple glove used for handling heated food, frozen food, and ice, which can be handled safely without feeling the heat or cold. A laminate comprising a thermoplastic resin foamed sheet has been proposed (Japanese Utility Model Publication No. 2-125918).

Further, in recent years, as a glove having antibacterial properties, a laminate having a two-layer structure of a polyethylene film layer in which an antibacterial agent is kneaded on the surface side of the glove and a polyethylene film layer having embossed inside the glove, Simple gloves made by stacking two sheets and fusing to form gloves have come to be used. Compared to conventional rubber gloves, this glove is made of polyethylene film, so it does not harden and harden easily, is flexible, and is easy to use. Also, since an antibacterial agent is contained on the surface side of the gloves, it is a food processing plant. It is used for sanitary handling of lunch boxes, kitchens, households and other foods.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional gloves have the following drawbacks. In other words, gloves made of flexible, closed-cell thermoplastic resin foam sheets are not necessarily antibacterial, so they are not always hygienically satisfactory when handling food and the like.

The polyethylene film gloves have excellent heat-sealing properties between the polyethylene film laminated bodies, but have poor heat insulating properties, so that the hands are not good when holding hot objects such as heated food or food. It becomes hot, and if you hold a cold object or frozen food, your hands will be cold and it will be difficult to hold for a long time, so you cannot safely use it for handling hot food or frozen food.

[0006]

[Means for Solving the Problems]

 In view of the above-mentioned conventional drawbacks, the present invention has been made with the object of providing a glove having antibacterial properties, excellent heat insulating properties, heat sealability, waterproof properties, and water resistance. The gist is a laminated body in which thermoplastic resin films are laminated on both sides of a flexible closed-cell thermoplastic resin foam sheet, and at least one of the thermoplastic resin films is a thermoplastic resin film containing an antibacterial agent. It is in gloves characterized by that.

[0007]

[Action]

 According to the glove of the present invention having the above-described structure, since the thermoplastic resin film is on both sides of the laminate having the three-layer structure, the two laminates of the present invention are stacked, or the laminate of the present invention is used. When thermoplastic resin films are overlapped and melt-fused, the thermoplastic resin films are welded together, so sufficient welding strength is maintained at the edges due to the melt-fusing, and excellent sealing properties, waterproofness, and water resistance are provided. . In addition, since at least one of the thermoplastic resin films contains antibacterial properties, it is excellent in hygiene and, in addition, the foamed sheet with closed cells, which has excellent heat insulation properties, is used. There is no sense of heat or coldness in cold foods or frozen foods or frozen foods, and when handling cold foods or frozen foods, there is no stiffness hardening compared to conventional rubber gloves. Further, since the foamed sheet has closed cells, it does not have water absorption or hygroscopicity, and the above-mentioned heat insulating property can be favorably maintained.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings showing an embodiment thereof. FIG. 1 is a partially enlarged cross-sectional view showing an example of a laminate used for the glove of the present invention. FIG. 2 is a partially enlarged cross-sectional view showing another example of the laminated body. In FIG. 1, reference numeral 1 denotes a laminated body in which a thermoplastic resin film 13 and a thermoplastic resin film 12 containing an antibacterial agent are laminated on both sides of a flexible closed-cell thermoplastic resin foam sheet 11. In FIG. 2, reference numeral 2 denotes a laminate in which a thermoplastic resin film 12 containing an antibacterial agent is laminated on both sides of a flexible closed-cell thermoplastic resin foaming sheet 11. The flexible closed-cell thermoplastic resin foam sheet used in the present invention is, for example, an olefin resin such as polyethylene, polypropylene, and a copolymer mainly composed of olefin, and the like, and the expansion ratio thereof is 2 to 60. A foamed sheet obtained by double-extruding and foaming is usually used. These foamed sheets are suitable because they are flexible and tough, and they are closed-cell foams and do not absorb water. By bridging these foamed sheets, the toughness and heat sealability can be further improved. As the thermoplastic resin film, for example, thermoplastic resin films of low-pressure, medium-pressure and high-pressure polyethylene, polypropylene, polyvinyl chloride, nylon, ionomer / polyvinyl alcohol, etc. are preferably used.

Next, the antibacterial agents used in the present invention include, for example, quaternary ammonium salt compounds, antibacterial apatite, that is, apatite solidified by exchanging and adsorbing antibacterial metal ions, antibacterial zeolite, that is, antibacterial. There are zeolites substituted with the metal ions of. Examples of antibacterial metal ions include silver, copper, zinc, bismuth, tin and thallium.

Further, the thermoplastic resin film 12 containing the antibacterial agent used in the present invention is obtained by kneading the antibacterial agent into the thermoplastic resin film. FIG. 3 is a partially cutaway plan view showing an example of a glove A produced by heat sealing using the laminate of the present invention. 4 (a), (b), and (c) are partially cutaway sectional views of the present invention, in which a laminate used for the glove of the present invention is formed on both sides of the palm side 3a and the instep side 3b. An example of a glove that has been made is shown. 4 (d) and 4 (e) are partially cutaway sectional views showing another example of the present invention. The palm side 3a is a laminate used for the gloves of the present invention, and the instep side 3b is an antibacterial agent. Examples of gloves formed by arranging thermoplastic resin films containing each are shown. 4 (f) and 4 (g) are partially cutaway sectional views showing other examples of the present invention, in which the laminated body of the present invention is provided on the palm side 3a and the thermoplastic resin film is provided on the instep side 3b. An example of a handbag formed by disposing two layers of a thermoplastic resin film containing an antibacterial agent is shown. In each of the gloves shown in FIG. 4, both sides 3a and 3b on the palm side and the back side are overlapped, and the five fingers are separated by fusion cutting, that is, at the same time, the periphery is heat-sealed except the wrist side opening. Reference numeral 4 indicates a heat seal portion. Therefore, it can be manufactured by the same means as the conventional plastic film gloves.

To explain FIG. 4 in detail, in the above-described embodiment, the glove of FIG. 4 (a) has a heat insulating property on both the palm side and the instep side when handling hot food or frozen food. The glove is made hygienic on both the volar side and the instep side of the glove. The glove of FIG. 4 (b) is a modified example of (a), in which the glove has a heat insulating property and the inside of the glove is sanitized. This is because depending on what is handled, hot or cold, it may not be necessary to place a thermoplastic film containing an antibacterial agent on both the volar and instep sides of the glove. For example, cold ice is dry ice. This is also because there are cases where the hands of workers must be protected to prevent bacteria. For example, when the worker's hand has a burn or an athlete's foot.

The glove of FIG. 4 (c) is a modified example of (a), in which a thermoplastic resin film containing an antibacterial agent is arranged on all of the inside and outside of the palm and instep of the glove. The glove of FIG. 4 (d) is a modified example of (a), and when it is used, a thermoplastic resin film containing an antibacterial agent is arranged on the instep side without having the heat insulating property.

The glove of FIG. 4 (e) is a modified example of (c), and when it is used, a thermoplastic resin film containing an antibacterial agent is arranged on the instep side without heat insulation. is there. The glove of FIG. 4 (f) is a modified example of (d), and since the antibacterial agent is expensive, the thickness of the thermoplastic resin film 12 containing the antibacterial agent on the outside is reduced to make the thermoplastic resin film 13 The cost can be reduced by using a laminate of the above.

The glove of FIG. 4 (g) is a modified example of (b), and is suitable when it is not necessary to give heat insulation to the instep side when using it, and in this case also, the antibacterial agent is expensive. Therefore, the cost can be reduced by using the one in which the thermoplastic resin film 12 containing the antibacterial agent on the outside is thinned and laminated on the thermoplastic resin film 13.

Since the thermoplastic resin films are welded to each other in the heat-sealing portion 4 of FIG. 4, the heat-sealing portion 4 has sufficient welding strength at the peripheral edge due to fusing and is excellent in sealing property, waterproof property and water resistance. The material, thickness and type of the antibacterial agent used for the gloves of the above-mentioned examples vary depending on the application, but for example, as an antibacterial agent, calcium phosphate among antibacterial apatites can be adsorbed on calcium phosphate by exchange adsorption. A solidified product, a polyethylene film having a thickness of 5 to 30 μm as the thermoplastic resin film 13, a thermoplastic resin, a foaming sheet 11 having a foaming ratio of 20 to 30 times, a foaming polyethylene sheet having a thickness of 0.1 to 4.0 mm, and an antibacterial agent. A thermoplastic resin film containing the above-mentioned polyethylene film in which the above-mentioned antibacterial agent is kneaded is particularly preferable in terms of heat insulation, hygiene and ease of use.

In the production of the above-mentioned glove A, the conventional automatic (deformation) manufacturing machine using a plastic film and the heat welding mold can be used as they are, and it is as easy as the case of the conventional plastic film gloves. It can be processed into low cost and can be manufactured at low cost. Moreover, when the palm side and the instep side of the gloves are overlapped and melt-fused, the thermoplastic resin films are welded to each other, so that the welding strength of the welded portion at the peripheral edge due to the welding is sufficiently maintained.

Depending on the application, the gloves may be shaped like mittens as shown in FIG. Further, embossing may be performed on the palm side, the instep side, and both sides of the glove, as needed.

[0018]

[Effect of device]

 As described above, the glove of the present invention has antibacterial properties and is excellent in heat insulating property, heat seal processability, waterproof property and water resistance. That is, since the thermoplastic resin films are welded to each other in the glove of the present invention, the welding strength of the heat-sealing portion is sufficiently strong that the gloves will not be damaged during the handling work, and have antibacterial properties depending on the condition of the product to be handled and the condition of the worker's hand. The glove can be placed only on the outside of the glove, only on the inside, or on both sides. In addition, when handling cold foods and frozen foods, there is less rigidity than conventional rubber gloves. Therefore, the glove of the present invention can be easily used for handling frozen foods, in various industrial fields, and at home.
