Description

Glove structure and method of manufacturing the same

Technical Field

The invention relates to a glove structure, in particular to a glove structure which has a simple structure and is easy to form, and a user can not easily accumulate sweat in the glove structure and/or can not easily press ulnar nerves to cause paralysis of the hand of the user when wearing the glove structure for a long time to work, and a manufacturing method of the glove structure.

Background

The prior art U.S. patent publication No. US2019/0387820a1 (hereinafter referred to as "document one") provides a glove structure comprising a glove core and an injection molded component, wherein an inner surface of the glove core is configured to contact a skin of a hand of a wearer, and an outer surface of the glove core is configured to receive the injection molded component. The literature relates to glove structures for work, sports and athletics, gardening and the like having injection molded components to improve protection of the wearer's hands. In the glove structure provided in the document, the injection molded component covers the glove core by 360 degrees, i.e. a complete circle or ellipse, when viewed from the cross section from the wrist portion to the fingertip portion, so that when the user wears the glove structure for a long time and works, the glove structure is not prone to sweat, which causes sweat to accumulate in the glove structure, which causes damp and stuffiness, and especially when the user works, as shown in fig. 1A, the little finger is usually under the thumb, which causes sweat to accumulate in the little finger side portion 91 of the conventional glove structure 9 and the palm side portion 92 close to the little finger side portion 91, which easily causes problems of sweat eruption, inflammation, skin breakage or blister generation in the little finger side and palm side portions of the user.

In addition, as shown in fig. 1B, there is actually one ulnar nerve UN from the little finger side of the hand of the human body to the humerus lower side and the shoulder blade lower side in this order, and when the stress of the glove structure provided in the document is applied to the little finger side for too long, the ulnar nerve UN is compressed at the little finger side, and the corresponding region R of the whole ulnar nerve UN is paralyzed.

The document also mentions that the injection-molded components on the outer surface of the glove core can be made of different Thermoplastic elastomer material compositions (TPE) according to different specific areas, which are produced by different injection-molding machines (injectors) respectively injecting different compositions into different specific areas of the mold cavity. For example, injection molding of the different specific regions may be accomplished in a two-step process, wherein a first set of thermoplastic elastomer materials, e.g., thermoplastic resins having a shore durometer of about 10 to 25, is injected into a first mold cavity formed by the first mold part for forming the first specific region of the first molded part, e.g., the area under the finger tips, and a second set of thermoplastic elastomer materials, e.g., thermoplastic resins having a shore durometer of about 60, is injected into a second mold cavity formed by the second mold part for forming the second specific region of the second molded part, e.g., the finger tip region. The design of document one results in a loss of sensitivity of certain areas of the wearer's hand, such as the fingertips, to gripping objects, which is contrary to the realism of the skin of a human hand, since in practice the dermis and epidermis layers of the hand skin should be uniform over at least the palm of the palm body and the finger face of the fingers. It will be appreciated that the lack of literature has led to the development of glove structures that conform to the aforementioned conformability and have different material compositions, since the literature is concerned with using different materials in different specific areas of the injection molded components of the glove structure for gripping and protective properties, thereby sacrificing the aforementioned conformability.

Detailed Description

Referring to fig. 2A, fig. 2B, fig. 2C, fig. 2D and fig. 3 of the present invention, fig. 2A, fig. 2B, fig. 2C, fig. 2D and fig. 3 illustrate details of a glove structure according to a first embodiment of the present invention. Referring to fig. 2A, the glove structure according to the first embodiment of the present invention comprises a glove core 10 and an injection molded component 20, wherein the injection molded component 20 covers at least a portion of the glove core 10. In the present invention, any object that presents a glove aspect is referred to herein as a glove core 10. For example, the glove core 10 may be a fabric made of cotton yarn, leather, wool, fiber, natural fiber, rayon, or nonwoven fabric, and the glove core 10 may be a knitted glove, a sewn glove, or a woven glove, or a dipped glove formed by dipping (dip coated) as disclosed in chinese patent No. 102754946, for example, a dipped glove in which at least a part of a region of a cotton yarn or nylon knitted glove is dipped by dipping to form a knitted glove having a colloid-coated outer surface. In the present invention, the injection molding assembly 20 may be in a half-palm shape, a partial palm shape or a full-palm shape, and the present invention is not limited thereto as long as it can cover a part of the glove core outside the groove described later. The injection molding assembly 20 is formed by solidifying a molding liquid, such as but not limited to plastic, rubber, polyvinyl chloride (PVC), and the like. The injection molded component 20 may also be a region of elastomeric material, such as Thermoplastic elastomer (TPE) or Thermoplastic rubber (TPR) or Thermoplastic Polyurethane (TPU), Thermoplastic vulcanizates (TPV) or Liquid Silicone Rubber (LSR) molded by injection molding (injection) over at least a portion of the glove core 10.

As shown in fig. 2B, the glove core 10 has a palm portion 101, a little finger portion 102, at least one finger portion 102 'other than the little finger portion 102 (e.g., thumb portion, index finger portion, middle finger portion, and ring finger portion), and the little finger portion 102 and the at least one finger portion 102' are connected to the palm portion 101. The little finger portion 102 has a finger surface 1021, a finger back 1022 opposite the finger surface 1021, and two

corresponding finger sides

1023, 1024 connecting the finger surface 1021 and the finger back 1022. Each of the two

finger sides

1023, 1024 has a finger base end FB, a finger tip end FF opposite to the finger base end FB, and the finger base end FB is connected with the palm body 101.

In order to make the glove structure less prone to sweat accumulation and pressure on the ulnar nerve, the injection-molded component 20 is formed with a little-finger-side groove SL1 between the base end FB and the tip end FF of the finger side 1024 of the little finger 102 close to the palm side 1011 of the palm portion 101, and a palm-side groove SL2 on the palm side 1011 of the palm portion 101, wherein the little-finger-side groove SL1 and the palm-side groove SL2 are communicated with each other, and preferably the little-finger-side groove SL1 and the palm-side groove SL2 expose a portion of the glove core 10 that is not covered by the injection-molded component 20, that is, the little-finger-side groove SL1 and the palm-side groove SL2 are not covered by the injection-molded component 20 and expose the glove core 10, for example, expose a fabric portion of the glove core 10 made of a cotton knitted glove. Through the above design, the cross section of the injection-molded component 20 of the glove structure covering the glove core is circular or elliptical with a break point when viewed from the palm 101 to the finger tip FF, that is, the injection-molded component 20 does not completely cover the glove core 10 by 360 degrees when viewed from the cross section. As shown in fig. 2A and 2C, the injection molding assembly 20 covers the outer periphery of the small finger 102 except for the small finger side groove SL1 (circulation reference); preferably, the injection molded component 20 covers the entire circumference of the little finger 102 except the little finger side groove SL1 in the length direction (the extending direction of the little finger) of the little finger 102, so that the end of the little finger side groove SL1 away from the palm side groove SL2 is the closed end SL11 sealed by the injection molded component 20, and the closed end SL11 is located at the fingertip end FF of the finger side 1024 of the little finger 102 or between the fingertip end FF and the base end FB. Also preferably, the little finger side groove SL1 is a tip (tip) FF1 extending to the little finger 102, the tip FF1 is the most distal point of the little finger 102 and the area with a radius of 0.5mm from the most distal point, when the closed end SL11 is located at the tip FF1 of the little finger 102; alternatively, the little finger side groove SL1 extends beyond the tip FF1 of the little finger 102, while the closed end SL11 is at the fingertip end FF, the base end FB or between the fingertip end FF and the base end FB of the finger side 1023 of the little finger 102 that is not adjacent to the palm side 1011 (i.e., the side opposite the finger side 1024). As shown in fig. 2A and 2D, that is, the injection molding assembly 20 covers the outer periphery of the palm portion 101 except for the palm-side groove SL 2; preferably, the injection molded component 20 covers the entire circumference of the palm portion 101 in the length direction (palm portion or palm-side extending direction) of the palm portion 101 except for the palm-side groove SL2, and one end of the palm-side groove SL2 away from the little finger-side groove SL1 is an open end SL21 which is not sealed by the injection molded component 20. Further, the width D2 of the volar-side groove SL2 and the width D1 of the little-finger-side groove SL1 are preferably larger than the width of the region corresponding to the ulnar nerve of the user, to thereby more effectively reduce the compression of the ulnar nerve by the glove structure. The width D2 of the palm-side groove SL2 is greater than or equal to the width D1 of the little finger-side groove SL 1. Preferably, the width D2 of the palm-side groove SL2 is greater than the width D1 of the little-finger-side groove SL1 because the user has more sweat on the palm-side portion than on the little finger-side, and because the thickness of the user's body is greater than the thickness of the little finger, the user will relatively feel pressure from the injection-molded component 20 contracting inside the palm when wearing the glove structure. The width D2 of palm-side groove SL2 is approximately 0.5mm to 2mm, and the width D1 of little finger-side groove SL1 is approximately 0.5mm to 3 mm. Specifically, the open end SL21 can release the pressure applied by the user's palm to the palm from the retraction of the injection molding assembly 20. The normal palm-side groove SL2 extends in the extending direction of the palm side 1011 and is located at the center of the palm side 1011, and the little finger-side groove SL1 extends in the extending direction of the finger side 1024 and is located at the center of the finger side 1024. Of course, for convenience of manufacture, the palm-side groove SL2 may extend along the extending direction of the palm side 1011 and be located between the center of the palm side 1011 and the palm back 1013 of the palm body 101, the little finger-side groove SL1 may extend along the extending direction of the finger side 1024 and be located between the center of the finger side 1024 and the finger back 1022, and the little finger-side groove SL1 and the palm-side groove SL2 may be formed without a parting line where an upper mold and a lower mold of a manufacturing mold for manufacturing a glove structure described later are combined with each other. It is to be noted that the palm-side groove SL2 may extend along the extending direction of the palm 1011 and be located between the center of the palm 1011 and the palm surface portion (not numbered) of the palm body 101, the little-finger-side groove SL1 may extend along the extending direction of the finger 1024 and be located between the center of the finger 1024 and the finger surface 1021, and similarly, the little-finger-side groove SL1 and the palm-side groove SL2 may be formed without a parting line at which an upper mold and a lower mold of a manufacturing mold for manufacturing a glove structure described later are combined with each other.

In the first embodiment, the small finger parts 102 except for the small finger side groove SL1 are covered by the injection molded component 20, the palm part 101 except for the palm side groove SL2 is covered by the injection molded component 20, and at least all of the finger parts 102', preferably all of the four finger parts 102' (thumb, index, middle and ring finger parts) are covered by the injection molded component 20. Furthermore, an included angle θ between the extending direction of the palm-side groove SL2 and the extending direction of the little finger-side groove SL1 is greater than or equal to 0 degree and less than or equal to 90 degrees, and preferably, the included angle θ is greater than 0 degree for ergonomics, and usually, the included angle θ is designed to be between 15 and 45 degrees, for example, 30 degrees, so that when the user relaxes his hand, the force applied can be reduced.

In addition, the injection molding assembly 20 may be integrally formed or composed of a plurality of different sub-injection molding assemblies, and the present invention is not limited thereto. The injection molding member 20 may be a decorative member to give the glove structure a design feeling and an aesthetic sense, or the injection molding member 20 may be one or a combination of a hard member, an insulating member, a corrosion-resistant member and an insulating member, which are selected to generally relate to the purpose of a user working with the glove structure, and the present invention is not limited to the type of the injection molding member 20.

As shown in fig. 3, when the user wears the glove structure of the first embodiment, since the little finger side grooves SL1 and the palm side grooves SL2 expose a portion of the glove core 10 that is not covered by the injection molding assembly 20, the external dry cool air a can enter the glove structure through the little finger side grooves SL1 and the palm side grooves SL2 and perform a heat exchange cycle (e.g., a flow direction of the cool air a), and the moisture LQ inside the glove structure, which is moist and hot, can be discharged outside the glove structure through the little finger side grooves SL1 and the palm side grooves SL 2. Therefore, accumulated sweat can be avoided in the glove structure, so that a user can not feel excessively sultry and damp after wearing the glove structure and working for a long time, the working time and the wearing feeling of the user are improved, and the occurrence of sweat eruption, inflammation, skin breaking or blisters is reduced.

Referring to fig. 4A and 4B of the present invention, fig. 4A and 4B illustrate details of a glove structure according to a second embodiment of the present invention. As shown in fig. 4A and 4B, unlike the first embodiment, the injection molded component 20 forms the stress relief groove SL3 and the communication groove SL4 in the palm back part 1013 of the palm part 101, the palm side groove SL2 communicates with the stress relief groove SL3 through the communication groove SL4, and the stress relief groove SL3 and the communication groove SL4 expose another part of the glove core 10 that is not covered by the injection molded component 20, so that the palm part 101 is covered by the injection molded component 20 except for the palm side groove SL2, the stress relief groove SL3 and the communication groove SL 4. In addition, the small finger 102 is covered by the injection molding assembly 20 in the region except for the small finger side groove SL 1. Since the thickness of the palm of the user is greater than that of the little finger, when the glove structure of the first embodiment is worn by the user, the user can relatively feel the pressure from the injection molding assembly 20 shrinking into the palm when wearing the glove structure of the first embodiment, and at this time, the second embodiment is designed with the stress relief groove SL3 and the stress relief groove SL3 is communicated with the palm groove SL2 through the communication groove SL4, and the open end SL21 of the palm groove SL2 is not sealed by the injection molding assembly 20, so that the pressure from the injection molding assembly 20 shrinking into the palm of the user can be released, and the user can reduce the applied force more, thereby providing better wearing feeling and more ergonomic design.

Further, as shown in fig. 4B, a portion of at least one finger portion 102 '(e.g., the index, middle and ring finger portions) forms at least one through hole HL, and the at least one finger portion 102' is entirely covered by the injection molded component 20 except for the at least one through hole HL. In the second embodiment, the at least one through hole HL is a plurality of through holes HL, and the through holes HL are not connected to each other, but in other embodiments, the through holes HL may be partially connected or completely connected, and the invention is not limited thereto.

Referring to fig. 5A and 5B of the present invention, fig. 5A and 5B show a cross-sectional structure of a glove structure including a little finger side groove and a palm side groove in a third embodiment of the present invention. As shown in fig. 5A and 5B, different from the first embodiment, the functional component 30 may be disposed between the glove core 10 and the injection molding component 20, and the little finger side groove SL1 and/or the palm side groove SL2 expose a portion of the functional component 30 that is not covered by the injection molding component 20, that is, the little finger side groove SL1 and/or the palm side groove SL2 do not cover the injection molding component 20 and expose the functional component 30, for example, expose the glue of the dipping glove formed by the dipping method, and the function of the functional component 30 may be, for example, waterproof, moisture permeable, or air permeable. Referring to fig. 6A and 6B of the present invention, the functional element 30 in the fourth embodiment of the present invention may also fill at least a part or all of the little finger side groove SL1 and/or the palm side groove SL2, so as to achieve better functions, such as better waterproof function. Preferably, the shore hardness of the functional component 30 is less than the shore hardness of the injection molded component 20 so that stresses during wear can be relieved or relieved when the functional component 30 is worn to reduce pressure on the ulnar nerve. Functional component 30 may also be another injection molded component of a different material than injection molded component 20 and may or may not be integrally molded with injection molded component 20.

Referring to fig. 7 of the present invention, fig. 7 is a view for explaining an embodiment of a manufacturing mold for manufacturing a glove structure. The manufacturing mold comprises a hand mold HM, an upper mold UM and a lower mold LM, which are used for manufacturing one of the glove structures in the above embodiments, wherein the hand mold HM is arranged between the upper mold UM and the lower mold LM. Preferably, the little finger portions of the hand mold HM are curved toward the palm surface portion of the hand mold HM. The hand mold HM is used for sleeving the glove core 10, and forms a mold cavity between the upper mold UM and the lower mold LM for receiving a molding liquid (for example, a hot-melted TPE or TPR, or an LSR at normal temperature), and the molding liquid is solidified (the TPE or TPR is cooled and solidified, and the LSR is heated and solidified) to form the injection molding assembly 20. The hand mold HM, the upper mold UM and the lower mold LM are designed with specific flow channel structures, the shape and structure of the specific flow channel structures are different corresponding to the front grooves, but the specific flow channel structures are designed to enable the molding liquid to be solidified into the injection molding assembly 20 to form the little finger side groove SL1 and the palm side groove SL2 so as to expose a part of the glove core 10 which is not covered by the injection molding assembly 20, thereby providing a glove structure which enables a user not to easily accumulate sweat in the glove structure and not to easily press ulnar nerve to cause hand paralysis when the user wears the glove structure for a long time to work.

The glove structure according to the fifth embodiment of the present invention provides a plurality of injection-molded components 20, which are composed of different sets of elastomer material compositions (e.g., a first set of elastomer material composition is composed of a transparent colorless elastomer material and an orange color master, and a second set of elastomer material composition is composed of a transparent colorless elastomer material and a white color master, where the plurality of sets of elastomer material compositions means that the injection-molded components 20 are composed of at least a first set of elastomer material composition and a second set of elastomer material composition. Still alternatively, a first group of thermoplastic elastomer materials, such as thermoplastic resins having a shore hardness of about 10 to 25, and a second group of thermoplastic elastomer materials, such as thermoplastic resins having a shore hardness of about 60. Referring to fig. 8 of the present invention, the method for manufacturing a glove structure according to the fifth embodiment is exemplified by two sets of elastomer materials, and the glove structure according to the fifth embodiment of the present invention is characterized in that the first set of elastomer materials and the second set of elastomer materials, which are composed of two sets of elastomer materials in the injection molding assembly 20, are extruded into continuous strips 41, 41 ' by an injection molding machine 40, 40 ', respectively, the strips 41, 41 ' are wrapped in the pipeline system 50, respectively, the strips 41, 41 ' are collected in the diversion module 42, and are combined by the two parallel strips 41, 41 ' into the molding cavity of the mold for manufacturing the glove structure through the pipeline system 50 after being combined into the molding liquid. Since the flow guiding module 42 does not mix the two strips 41, but only injects the two strips 41, 41' into the mold cavity after they are contacted in parallel, the flow of the molding liquid in the mold cavity may cause the first group of elastomer material and the second group of elastomer material in the injection molding assembly 20 to be irregularly distributed, where the irregular distribution refers to the irregular distribution of the first group of elastomer material and the second group of elastomer material on the upper surface and/or the irregular distribution of the lower surface of the injection molding assembly 20 and/or the irregular distribution of the cross section (thickness direction) of the injection molding assembly 20. In other words, the present invention does not use different materials in different specific regions of the injection-molded component as in the document, but rather the first and second sets of elastomeric materials of the present invention are irregularly distributed in the injection-molded component 20 and appear simultaneously even in specific regions, for example, even if the first and second sets of elastomeric materials appear simultaneously in specific regions such as fingertip regions or regions below fingertips, or even if the first and second sets of elastomeric materials appear simultaneously in each region, so that the injection-molded component 20 of the present glove structure conforms to a consistent glove structure having different material compositions. Or the first group of elastomer material compositions and the second group of elastomer material compositions are different colors, so that the injection molding component 20 of the glove structure of the invention presents a jet shape, independent colors and different colors which are irregularly distributed on the injection molding component 20.

In the injection step P3, the first and second sets of elastomer material compositions are extruded from an injection molding machine 40, 40 ' to form continuous strips 41, 41 ', the strips 41, 41 ' are covered and transported by the pipe system 50, the pipe system 50 collects the strips 41, 41 ' at one end of the flow guide module 42 and forms two parallel strips 41, 41 ' in parallel and in contact with each other from the other end of the flow guide module 42 to combine into the molding liquid, and the molding liquid is covered by the pipe system 50 and transported to be injected into the cavity of the mold.

After completion of glove structure step P4, the molding liquid is allowed to solidify in the mold cavity to form a glove structure in which the injection molded component 20 is wrapped around at least a portion of the glove core 10, and the glove structure is released from the hand mold HM.

After the mold HM, the upper mold UM and the lower mold LM are assembled, a flow channel structure is designed, the flow channel structure corresponds to a structure that after the molding liquid is solidified into the injection molding assembly 20, a little finger side groove SL1 and a palm side groove SL2 are formed, and the little finger side groove SL1 and the palm side groove SL2 are communicated with each other to expose a portion of the glove core 10 that is not covered by the injection molding assembly 20.

In summary, the glove structure, the manufacturing mold thereof and the manufacturing method thereof provided by the invention have the advantages that the structure is simple, the forming is easy, and the glove structure and the manufacturing mold thereof can prevent the hand of the user from being paralyzed due to the fact that sweat is easy to accumulate in the glove structure and/or ulnar nerve is not easy to be pressed when the user wears the glove structure for working for a long time. Therefore, a user wearing the glove structure can feel comfortable and can work for a longer time, and the time for taking a rest due to discomfort caused by damp, sultry or ulnar nerve compression is reduced. Moreover, each region of the injection molded component has both the first set of elastomeric material composition and the second set of elastomeric material composition present, so that the injection molded components of the glove structure of the present invention conform to the same.
