Description

  The present invention relates to a glove that can be used as a disposable glove.

Conventionally, as this type of glove, there is a disposable glove in which a set of soft sheet materials (plastic film) is overlapped and connected to each other by heat sealing (for example, see Patent Document 1).
In the disposable glove, the width of at least one of the four finger portions excluding the thumb is the largest in the middle position from the width of the finger base adjacent to the palm portion when the glove is flat. The degree of fitting is improved by spreading the thumb portion and the middle finger portion so that the angle between the respective longitudinal axes is 40 ° to 60 °.
In addition, this type of glove is in a state where a pair of soft sheet materials are flatly overlapped when not worn (when not worn) when the user's hand is not inserted, and used when worn (when worn) When a person's hand is inserted, the part of each finger swells and deforms three-dimensionally. For this reason, each finger part, the back of the hand, and the like are set to be larger than normal working gloves, and are configured to generate appropriate slack (margin) when the hand is inserted.

JP-A 63-303104

However, in such a conventional glove, since the vertical axis (center axis) of the thumb portion is formed in a straight line, the straight cylindrical thumb portion matches the warped shape of the thumb in a three-dimensional deformation state when worn. At the same time, only a small portion of the thumb abdomen was in close contact with the straight cylindrical thumb portion.
As a result, looseness occurred between the straight cylindrical thumb portion and the abdomen of the thumb when worn, and the abdomen of the thumb did not fit to the thumb portion as a whole.
As a result, if you perform an action such as picking an object while wearing a glove, the abdomen of the thumb will be displaced relative to the straight cylindrical thumb part, and the object may fall off or the glove may come off during operation. There was a problem.
In particular, dishwashing using a slippery detergent has a problem that the tableware cannot be reliably washed and there is a risk that the tableware may slide down if the operator is not careful.

In order to achieve such a subject, the glove concerning the present invention comprises at least the composition concerning the following independent claim.
[Claim 1] A glove formed by heat-sealing two overlapping soft sheet materials,
A first finger into which the thumb is inserted, a second finger into which the index finger is inserted, a third finger into which the middle finger is inserted, a fourth finger into which the ring finger is inserted, and a second finger into which the little finger is inserted. With five fingers,
The first finger part has a curved center line gradually separating from the center line of the third finger part toward the fingertip side, and a curved welded part tapered toward the fingertip side facing the abdomen of the thumb. A glove characterized by comprising:

It is explanatory drawing which shows the whole structure of the glove which concerns on embodiment of this invention, and is a front view at the time of non-wearing seen from the palm side. It is a rear view at the time of non-wearing seen from the back side of the hand. It is the external view seen from the fingertip side at the time of wear.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 3, the glove A according to the embodiment of the present invention can be used as a disposable glove formed by heat-sealing two overlapping soft sheet materials A1 and A2 into a hand shape. It is a thing. Thereby, there is no difference between the back and the front, and it is used as a pair of left and right gloves by preparing two.
That is, when the glove A is not worn (when not worn) in which the user's hand B is not inserted, as shown in FIGS. 1 and 2, the entire soft sheet material A1, A2 overlaps flatly. It has become. When the hand B is worn (attached), as shown in FIG. 3, each finger part swells and deforms three-dimensionally as the hand B is inserted.
More specifically, the glove A according to the embodiment of the present invention includes a first finger part 1 into which the thumb 10 is inserted, a second finger part 2 into which the index finger 20 is inserted, and a middle finger 30 as each finger part. The third finger part 3 to be inserted, the fourth finger part 4 into which the ring finger 40 is inserted, and the fifth finger part 5 into which the little finger 50 is inserted are provided as main components.

As the soft sheet materials A1 and A2, it is preferable to use a synthetic resin film having heat-welding properties.
Specific examples of the synthetic resin film used for the flexible sheet materials A1 and A2 include polyethylene (high density polyethylene, low density polyethylene, linear low density polyethylene, linear ultra-low density polyethylene), and an ethylene-based thermoplastic elastomer. Polyolefins such as ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, ethylene-styrene copolymer, ethylene ionomer, ethylene-vinyl alcohol copolymer, polypropylene (isotactic homopolypropylene, syndi Tactic homopolypropylene, random polypropylene, block polypropylene) with addition of thermoplastic elastomer such as styrene thermoplastic elastomer and olefin thermoplastic elastomer, thermoplastic polyurethane Examples include polystyrene containing a copolymer of ethylene, acrylonitrile, and methyl methacrylate with a thermoplastic elastomer such as a styrene thermoplastic elastomer or nitrile thermoplastic elastomer, or a flexible thermoplastic resin such as soft polyvinyl chloride. It is done.
Among these, polyethylene such as low density polyethylene and high density polyethylene is preferably used. On the other hand, a soft but thermosetting material such as rubber cannot be used due to poor workability.
When a thin polyethylene resin film of 20 μm or less is used as the thickness of the synthetic resin film used for the soft sheet materials A1 and A2, when the large movement such as picking an object in the worn state is performed, The arranged flexible sheet material A1 itself is stretched. For this reason, although a feeling of tension is relieved, there is a possibility that strength is low and durability is inferior. Use of a polyethylene resin film having a thickness of 20 μm to 50 μm is preferable because the strength is improved and the durability is excellent. In particular, a polyethylene resin film having a thickness of 20 μ to 30 μ is excellent in the feeling of use.

As a heat sealing method for the soft sheet materials A1 and A2, there is a method in which two overlapping soft sheet materials A1 and A2 are simultaneously cut into a hand shape and thermally welded by a heated cutting die (not shown). In addition, there is a method in which two soft sheet materials A1 and A2 previously cut into a hand shape are overlapped and thermally welded.
The manufacturing method of the glove A by the cutting die is intermittently fed in a state where the strip-shaped soft sheet materials A1 and A2 are overlapped, and each time the glove A is fed out slightly longer than the width dimension of the glove A, the heated cutting die is replaced with the soft sheet. Press against the materials A1 and A2. As a result, the soft sheet materials A1 and A2 are welded into a predetermined hand shape and are simultaneously punched to create one glove A.
A heat seal portion A4 is formed on the outer peripheral edge of the created gloves A except for the insertion port A3 into which the hand B is inserted.

And the 1st finger part 1, 2nd finger part 2, 3rd finger part 3, 4th finger part 4, and 5th finger part 5 of glove A have each center line 1a, 2a, 3a, 4a, 5a. The heat seal portions A4 of the fingertips are each formed in an arc shape.
The first finger portion 1 is directed toward the fingertip side facing the abdomen 11 of the thumb 10 and the curved center line 1a gradually separating from the second finger portion 2 and the third finger portion 3 and the like. It has a curved weld 1b that is tapered.
The center line 1 a of the first finger 1 is formed in a straight line at a portion facing the proximal joint 14 from the third joint (MP joint) 12 of the thumb 10 to the second joint (IP joint) 13. The part of the center line 1a that faces the terminal node 15 from the second joint 13 to the fingertip is formed in a curved shape that gradually separates from the center line 2a of the second finger part 2 and the center line 3a of the third finger part 3. .
The curved welded portion 1b is a portion facing the abdomen 11 which is the inside of the thumb 10 in the heat seal portion A4, and a portion facing the terminal node 15 extending from the second joint 13 to the fingertip is along the outer shape of the abdomen 11. It is formed in a tapered curve shape.

Either the second finger part 2, the third finger part 3, the fourth finger part 4 or the fifth finger part 5 except the first finger part 1, or the second finger part 2, the third finger part 3, the fourth It is preferable that all of the finger part 4 and the fifth finger part 5 have a bulging part 6 in which a part facing the part from the base node to the middle part of each finger inserted into each tube bulges outward in a cylindrical shape.
The bulging portion 6 has only a portion facing the portion from the base clause to the middle clause of each finger in the second finger portion 3, the third finger portion 3, the fourth finger portion 4, and the fifth finger portion 5, respectively. It is comprised so that it may expand about 5 to 15% rather than the fingertip side. As a result, a space S is formed between the bulging portion 6 and a portion extending from the proximal joint including the third joint of each finger to the middle joint including the first joint (DIP joint).

In the case of the example shown in FIGS. 1 to 3 as a specific example of the bulging portion 6, the second finger portion 2 has a second joint (PIP joint) 22 sandwiched from the proximal joint 21 of the index finger 20 in the second joint. A bulging portion 62 is formed at a portion facing the portion reaching the node 23. In the illustrated example, only the first finger part 1 side of the second finger part 2 is inflated as the bulging part 62 of the second finger part 2. Accordingly, a space S is formed between the third joint 24 to the first joint 25 of the index finger 20 and the bulging portion 6.
In the third finger portion 3, a bulging portion 63 is formed at a portion facing a portion from the proximal joint 31 of the middle finger 30 to the middle joint 33 across the second joint 32. Thereby, a space S is formed between the third joint 34 to the first joint 35 of the middle finger 30 and the bulging portion 6.
In the fourth finger portion 4, a bulging portion 64 is formed at a portion facing a portion from the proximal joint 41 of the ring finger 40 to the middle joint 43 across the second joint 42. Thereby, a space S is formed between the third joint 44 to the first joint 45 of the ring finger 40 and the bulging portion 6.
Further, although not shown as another example, the bulging portion 62 of the second finger portion 2 can be changed to have a symmetrical shape with the center line 2a as the center in the same manner as the other bulging portions 63 and 64. It is.

Further, the second finger part 2, the third finger part 3, the fourth finger part 4 or the fifth finger part 5, or the second finger part 2, the third finger part 3, the fourth finger part 4 and the second finger part 4 It is preferable that all of the five finger portions 5 have a narrowed portion 7 having a diameter smaller than that of the bulging portion 6 on the fingertip side with respect to the portion facing the first joint of each finger inserted therein.
In the case of the example shown in FIG. 1 to FIG. 3 as a specific example of the restricting portion 7, the restricting portion 72 is provided at a portion of the second finger portion 2 that opposes the terminal joint 26 on the fingertip side with respect to the first joint 25 of the index finger 20. Forming.
In the third finger portion 3, a narrowed portion 73 is formed at a portion facing the distal node 36 on the fingertip side with respect to the first joint 35 of the middle finger 30.
In the fourth finger portion 4, a constricted portion 74 is formed at a portion that faces the distal node 46 on the fingertip side of the ring finger 40 from the first joint 45.

On the other hand, in FIG.1 and FIG.2, the glove A at the time of flat unwearing before insertion of the hand B is shown. However, the user's hand B indicated by a two-dot chain line is a three-dimensional appearance. Therefore, between the first finger part 1 and the thumb 10, between the second finger part 2 and the index finger 20, between the middle finger 30 of the third finger part 3, between the ring finger 40 of the fourth finger part 4, and the fifth finger. There seems to be a gap between the part 5 and the little finger 50.
On the other hand, FIG. 3 shows the gloves A when the hand B is worn after insertion, and the insertion of the hand B causes each finger portion to swell and deform three-dimensionally, so the gap is reduced.
As a result, the outer peripheral surface of the thumb 10 contacts the inner peripheral surface of the first finger portion 1, the outer peripheral surface of the index finger 20 contacts the inner peripheral surface of the second finger portion 2, and the inner peripheral surface of the third finger portion 3. The outer peripheral surface of the middle finger 30 contacts, the outer peripheral surface of the ring finger 40 contacts the inner peripheral surface of the fourth finger portion 4, and the outer peripheral surface of the little finger 50 contacts the inner peripheral surface of the fifth finger portion 5.

According to the glove A according to the embodiment of the present invention, when the user's hand B is inserted and the thumb 10 is inserted into the first finger 1, the first finger 1 is inflated and three-dimensionally. Deform.
In this three-dimensionally deformed state, the curved center line 3a of the first finger 1 and the warped shape of the thumb 10 generally match, and the abdomen 11 of the thumb 10 is entirely along the curved welded portion 1b that is tapered toward the fingertip side. Closely.
Furthermore, during the operation of picking up an object, the curved welded portion 1b passes through the abdomen 11 of the thumb 10 to form a convex shape, so that the frictional force generated between the object and the object increases, making it difficult to slip.
Therefore, the abdomen 11 of the thumb 10 can be fitted entirely to the first finger 1 when worn.
As a result, the curved welded portion of the first finger portion 1 can be obtained even when an operation is performed such as gripping an object with the glove A being worn, as compared with the conventional one in which the central axis of the thumb portion is formed in a straight cylindrical shape. 1b and the abdomen 11 of the thumb 10 are not displaced, and it is possible to prevent the object from being displaced during operation and the glove A from coming off.
In particular, it is possible to prevent the tableware from slipping down even when the dishwashing is performed using a slippery detergent, and the safety in slippery work using the detergent can be improved.

Further, any or all of the second finger part 2, the third finger part 3, the fourth finger part 4 and the fifth finger part 5 are opposed to the part extending from the base joint to the middle joint of each finger inserted into each. It is preferable that the part to perform has the bulging part 6 which swells outside in a cylindrical shape.
In such a case, by inserting the index finger 20, the middle finger 30, the ring finger 40, and the little finger 50 by inserting the hand B, a portion extending from the proximal joint including the third joint to the middle joint including the first joint of each finger. A space S is formed between the bulging portion 6 and the bulging portion 6.
Thereby, the soft sheet material A2 on the back side of the hand B can be bent from the third joint to the first joint of each finger without stretching.
Therefore, each finger (index finger 20, middle finger 30, ring finger 40, little finger 50) can be smoothly moved without resistance.
As a result, it becomes easy to perform an operation of picking an object while wearing the gloves A, and the usability is improved.

In addition, any or all of the second finger part 2, the third finger part 3, the fourth finger part 4 and the fifth finger part 5 are fingertips than the part facing the first joint of each finger inserted into each of them. It is preferable to have the narrowed part 7 thinner than the bulging part 6 on the side.
In such a case, by inserting the index finger 20, middle finger 30, ring finger 40, and little finger 50 by inserting the hand B, the distal end of the fingertip side closer to the first joint of each finger is in close contact with the narrowed portion 7. .
Accordingly, the fingertips of the fingers can be fitted to the narrowed portions 7 of the second finger portion 2, the third finger portion 3, the fourth finger portion 4, and the fifth finger portion 5 at the time of wearing.
As a result, the second finger portion 2, the third finger portion 3, the fourth finger portion 4, the fifth finger portion 5, and the throttling portion 7, and the index finger 20, the middle finger 30, the ring finger 40, and the little finger 50 are displaced. Therefore, it is possible to prevent the object from slipping off and the glove A from coming off during operation.

In the illustrated embodiment, the bulging portion 6 and the narrowed portion 7 are formed in the second finger portion 2, the third finger portion 3, and the fourth finger portion 4 in the illustrated example, but the present invention is not limited to this. The bulging portion and the narrowing portion may be formed on the fifth finger portion 5.
That is, by forming a bulging portion in the fifth finger portion 5 at a portion facing the portion extending from the proximal joint 51 of the little finger 50 to the middle joint 53 across the second joint 52, the third finger 54 of the little finger 50 It is also possible to change so that a space is formed between the first joint 55 and the first joint 55.
Further, it is possible to form a narrowed portion at a portion of the fifth finger portion 5 that faces the distal node 56 on the fingertip side of the first joint 55 of the little finger 50.
