Technical Field

The invention relates to a shoe cover, in particular to a shoe cover with a reinforced edge of a sleeve opening so as to be difficult to pull open. The invention further relates to a method for manufacturing the shoe cover.

Background

The shoe cover is used for being sleeved on a shoe to prevent pollutants on the shoe from polluting the environment or prevent environmental pollutants from polluting the shoe. In the environment with high requirement for environmental cleanness, such as dust-free workshops in precision manufacturing industry, sterile workshops in food and pharmaceutical industry, operating rooms and other occasions, people are generally required to wear shoe covers. In addition, with the development of society and the improvement of living standard of people, people pay more and more attention to indoor sanitation. Many households will prepare shoe covers to be worn by guests when they enter the room, so as to prevent the guests' shoes from soiling the floor in the room.

The prior shoe covers are mostly made of non-woven fabrics, Polyethylene (PE) or Chlorinated Polyether (CPE). The shoe cover made of polyethylene has good water and moisture resistance, but is not resistant to oil and organic vapor, and the shoe cover made of chlorinated polyether has excellent oil resistance, heat resistance and flame retardance. In addition, the shoe covers made of polyethylene and chlorinated polyether have a relatively poor resistance to mechanical stresses, such as tensile properties. When a user puts the shoe cover on a shoe, especially when the shoe cover is thin, the shoe cover made of polyethylene and chlorinated polyether is easy to tear. When a user puts the shoe cover on a shoe, the shoe cover made of polyethylene and chlorinated polyether is easy to tear particularly at the sleeve opening part or the sleeve opening periphery of the shoe cover. In addition, the shoe cover made of polyethylene and chlorinated polyether has poor air permeability, and when the shoe cover is used in a high-temperature environment, the air permeability of the feet of a user is easy to be poor. Compared with the shoe cover made of polyethylene or chlorinated polyether, the shoe cover made of non-woven fabric has better tensile property. However, the non-woven fabric has a large friction force with the ground, and the shoe cover made of the non-woven fabric is not resistant to abrasion caused by long-time walking of a user.

Preferably, the second cuff portion 22 of the cuff periphery 20 is sealed to the first cuff portion 21.

As shown in FIGS. 2A to 2C of the drawings, the first cuff portion 21 of the cuff periphery 20 of the shoe cover according to the present invention comprises a first base layer 211 and a first reinforcing layer 212, wherein the first base layer 211 extends outwardly from the cuff body 10. Further, the first substrate layer 211 is integrally formed with the glove body 10, and the first reinforcing layer 212 is disposed on an outer surface of the first substrate layer 211. Accordingly, the first substrate layer 211 of the first cuff portion 21 and the second cuff portion 22 are sealed together. Preferably, the first substrate layer 211 and the sheath body 10 are made of polyethylene film, polypropylene film or chlorinated polyether film, and the first reinforcing layer 212 is made of non-woven fabric. More preferably, the first socket portion 21 and the second socket portion 22 are welded together by ultrasonic welding. Optionally, the first sleeve portion 21 and the second sleeve portion 22 are heat sealed together.

As shown in fig. 2A to 2C of the drawings, the second cuff portion 22 of the cuff periphery 20 of the present invention according to the embodiment of the present invention comprises a second substrate layer 221 and a second reinforcing layer 222, wherein the second substrate layer 221 of the second cuff portion 22 and the first substrate layer 211 of the first cuff portion 21 are integrally formed, the second reinforcing layer 222 of the second cuff portion 22 and the first reinforcing layer 212 of the first cuff portion 21 are integrally formed, and the first substrate layer 211 of the first cuff portion 21 and the second substrate layer 221 of the second cuff portion 22 are sealed together.

As shown in fig. 2A to 2C of the drawings, it can be understood that when the elastic band 30 of the shoe cover according to the present invention is disposed between the first cuff portion 21 and the second cuff portion 22 of the cuff periphery 20 according to the embodiment of the present invention, the elastic band 30 is appropriately stretched, so that the elastic band 30 can automatically contract and bind the shoe cover to the user's shoe when the shoe cover according to the present invention is fitted on the user's shoe (or foot). In other words, the elastic band 30 can undergo automatic contraction when the cover of the invention is in natural disposition, without being subjected to external forces; when the user's shoe is placed in the receiving cavity 101 formed by the sleeve body 10, the elastic band 30 is stretched and tied to the user's shoe (or foot, ankle, etc.), so that the shoe cover is not easily separated from the user's shoe or foot.

It should be noted that, in order to make the shoe cover of the present invention have better strength and tensile strength, the covering body 10, the first base layer 211 of the first covering opening portion 21 of the covering opening periphery 20 and the second base layer 221 of the second covering opening portion 22 of the shoe cover are made of a whole piece of fabric, and the first reinforcing layer 212 of the first covering opening portion 21 and the second reinforcing layer 222 of the second covering opening portion 22 are made of a whole piece of fabric. In addition, when the first substrate layer 211 of the first cuff portion 21 and the second substrate layer 221 of the second cuff portion 22 are made of polyethylene film, polypropylene film or chlorinated polyether film, the first cuff portion 21 and the second cuff portion 22 are preferably heat-sealed together.

Preferably, the manufacturing material or raw material of the sleeve body 10 of the shoe cover according to the embodiment of the present invention is chlorinated polyether, and the manufacturing material of the first reinforcing layer 212 of the first cuff portion 21 and the second reinforcing layer 222 of the second cuff portion 22 of the cuff periphery 20 is non-woven fabric. Since the second substrate layer 221 of the second cuff portion 22 of the cuff periphery 20 of the cover of the present invention is disposed on the inner surface of the first substrate layer 211 of the first cuff portion 21, the first reinforcing layer 212 of the first cuff portion 21 and the second reinforcing layer 222 of the second cuff portion 22 of the cuff periphery 20 of the cover of the present invention are disposed outwardly. Accordingly, the cover body 10 of the shoe cover of the present invention is made of chlorinated polyether film, which can effectively prevent water and oil, and the first reinforcing layer 212 of the first opening portion 21 and the second reinforcing layer 222 of the second opening portion 22 of the cuff periphery 20 are made of non-woven fabric, which can improve the tensile property of the cuff periphery 20 of the shoe cover, thereby preventing the cuff periphery 20 of the shoe cover from being easily torn as most existing shoe covers. For example, fig. 1A and 1B illustrate a method of manufacturing a cover having a fabric entirely of a polyethylene film or a chlorinated polyether film, which is easily torn by a user when the user wears the cover on a shoe due to various factors. Firstly, when the shoe cover shown in fig. 1A and 1B is worn by a user, the periphery of the opening of the shoe cover is easily torn due to the concentrated stress. Secondly, the shoe cover made of the polyethylene film or the chlorinated polyether film is made of the materials, when the periphery of the opening of the shoe cover is sealed together, the tensile property of the part of the periphery of the opening of the shoe cover connected with the cover body is reduced, and the shoe cover is further easily torn. Finally, the shoe cover with the fabric totally made of the polyethylene film or the chlorinated polyether film is easy to generate static electricity. Generally, the generation of static electricity in the cover is often associated with friction between the cover and the user's clothing. The cuff periphery 20 of the cover of the present invention is made of non-woven fabric, which when placed on the cuff body 10, separates the cuff body 10 from the user's clothing, such as pants. Therefore, the shoe cover of the present invention is made of nonwoven fabric only at the cuff periphery 20, so that the generation of static electricity between the shoe cover and the user's clothes can be substantially prevented. The shoe cover only has the cuff periphery 20 made of non-woven fabric, and can reduce the use of the non-woven fabric as much as possible so as to reduce fiber shedding caused by the non-woven fabric. Therefore, the shoe cover not only solves the defect that the periphery of the sleeve opening of most of the existing shoe covers is easy to tear or tear, but also keeps the advantages of non-woven fabric shoe covers, such as difficult generation of static electricity, small usage amount of non-woven fabrics, good waterproof performance, damage caused by excessive heat seal of the periphery of the sleeve opening of the shoe cover and the like.

As shown in figures 2A to 2C of the drawings, the density of the welds at the cuff periphery 20 at the front 41 and rear 42 of the cover of the present invention according to an embodiment of the present invention is greater than the weld density at other parts of the cuff periphery 20 to enhance the welding of the cuff periphery 20 at the front 41 and rear 42 of the cover of the present invention and to prevent the elastic band 30 from coming off the cuff periphery 20. Furthermore, when the cover of the invention is unfolded to allow the user to fit over a shoe (or foot), the cover will be expanded longitudinally, and the enhanced welding of the cuff periphery 20 at the front 41 and rear 42 ends of the cover of the invention helps to prevent the cover of the invention from tearing open.

Accordingly, the first spigot portion 21B and the second spigot portion 22B face outwardly. Preferably, the sheath body 10 is made of a polyethylene film, a polypropylene film and a chlorinated polyether film, and the first cuff portion 21B and the second cuff portion 22B are made of a nonwoven fabric.

Further, the elastic band 30 is held between the first cuff portion 21B and the second cuff portion 22B. Preferably, the second cuff portion 22B just touches or does not touch the jacket peripheral edge 11.

(a) respectively placing two second fabrics at two edges of the first fabric;

(b) respectively pressing the second fabric and the first fabric together to form a corresponding composite fabric;

(h) The sealing parts formed by the first fabric and the composite fabric are longitudinally cut, so that the first fabric layer, the elastic band and the composite fabric between two adjacent sealing parts form a shoe cover.

As shown in fig. 3 to 5E of the accompanying drawings, when the shoe cover fabric is made into the shoe cover, a plurality of processing procedures and a plurality of raw materials are required. As shown in fig. 3 to 5E of the drawings, according to an embodiment of the present invention, the raw materials for manufacturing the shoe cover of the present invention include a first fabric 1, a second fabric 2 and an elastic band raw material 3, wherein the second fabric 2, e.g., the second fabric 2a and the second fabric 2b, are placed on the first fabric 1 along both edges of the first fabric 1 and are pressed together to form a composite fabric 4 (a composite fabric 4a and a composite fabric 4 b). In order to improve the combination of the two, a double-sided pressing manner can be adopted, so that the combination between the two is more compact. In addition, in practice, it is found that when the first fabric 1 of the plastic film made of polyethylene or polypropylene and the second fabric 2 made of non-woven fabric are pressed at normal temperature, the two fabrics are not easy to form tight combination. The first fabric 1 made of polyethylene is kept at 115 ℃ to 135 ℃, or the first fabric 1 made of polypropylene is kept at 150 ℃ to 176 ℃, so that the first fabric 1 is combined with the second fabric 2a and the second fabric 2b made of non-woven fabric more firmly, and has good formability and more uniform thickness.

In order to improve the combination of the two, a double-sided pressing manner can be adopted, so that the combination between the two is more compact. As shown in fig. 6 to 7 of the drawings, the second fabric 2a and the second fabric 2b are disposed to partially overlap the edge of the first fabric 1, and the remaining portion extends outward from the edge of the first fabric 1. The first facing material 1 and the second facing material 2 made of non-woven fabric are pressed into a shape by double-faced rolling.

As shown in fig. 6 to 7 of the drawings, the first sheet 1 and the second sheet 2 are unfolded and pulled at the operation table 5 of the production line after the double-side roll forming, at which time the elastic band material 3 (elastic band material 3a and elastic band material 3b) is placed on the inner surfaces of the second sheet 2a and the second sheet 2b, respectively, and then the second sheet 2a and the second sheet 2b are both folded and form the corresponding first cuff portion and second cuff portion, respectively, and the first cuff portion and the second cuff portion are laterally sealed together, respectively, so that the elastic band material 3 is held between the first cuff portion and the second cuff portion, respectively.
