Abstract

A latex glove having less number of sizes and types, having less clearances and loosenesses at the finger tips of a wearer, and fitted to the hands of a variety of sizes. The latex glove (1) comprises extension parts (3) having bellows portions extended by the insertion of fingers which are formed near the finger root parts of finger fitting parts (2a) in which a first finger (thumb), a second finger (index finger), and a third finger (middle finger) are inserted. The glove is manufactured so that the overall lengths of the finger fitting parts (2a) are reduced less than the fully extended lengths by amounts approximately equal to lengths by which the extension parts (3) are extended to apply tensions to the finger tips inserted into the finger fitting parts (2a). Also, the glove (1) comprises two restriction parts (5) at a position around the hand passed through between the first and second fingers and the wrist side of the third joint of the fifth finger and near a position around a wrist.

Description

Specification

Latex glove technical field

[0001] The present invention relates to a latex glove.

Background art

[0002] Currently, so-called disposable latex gloves are widely used in medical settings. Latex gloves are made of elastic materials such as latex and have moderate elasticity. Latex gloves are generally produced by immersing a hand-shaped mold in an emulsion or dispersion of natural latex or synthetic latex and curing it on the mold. Commercially available latex gloves are generally manufactured in a size that is expanded to about 5 sizes and 7 types in terms of hand size and finger length. In order to ensure compatibility and operability, the user selected an appropriate size from among the developed sizes and used it.

[0003] However, in actuality, the length of the finger of the user varies widely, and even if the glove is selected with an appropriate size from among the deployment sizes, the fingertip portion may be left over depending on the usage situation and usage conditions. It is difficult to use. For example, when a delicate work such as picking a small instrument, operating a device, or touching with a fingertip is required, it is often impossible to work as expected, and as a result, a serious work mistake can be made. It can be. In addition, in order to avoid surplus fingertips, the size is slightly smaller, and if a glove is selected, strong pulling force acts on the entire hand, resulting in sluggish wearing hands and reduced usability. There was also a problem. And due to the nature of latex, the fingertips and other parts of the hand stretched during use, and the clogged parts start to loosen, and the loosened parts must be pulled up repeatedly during use. It was. Of course, it is possible to increase the size variation and make it possible to select a more suitable glove S, which increases production and purchase costs, and this method is difficult in terms of cost.

[0004] On the other hand, not only latex gloves, but also gloves that take into account the extensibility when bending fingers are disclosed in, for example, Japanese Utility Model Publication No. 64-51618 (Patent Document 1) and Japanese Utility Model Publication No. 58-12223 (patent documents). It is disclosed in the literature 2). These gloves are provided with a bellows (bellows part) on the bent part or the entire glove, and the bellows is extended when the finger joint or the wrist joint is bent. As a result, when the finger or wrist is bent, the bellows on the back side of the hand is extended.

[0005] However, since the glove of Patent Document 1 has a bellows only on the back side of the hand, it is necessary to prepare a glove for each of the left hand and right hand, and an increase in manufacturing cost can be avoided. Absent. Since left and right are determined, only left-handed gloves can be worn on the left hand and right-handed gloves on the right hand, and must always be used in pairs. For this reason, if only one of the very inconvenient uses is additionally used, the remaining one will be left, which increases waste.

[0006] Since the bellows of the glove in Patent Document 2 is annular, there is no such disadvantage! In addition, the latex glove is made so as to be in close contact with the fingers and the back of the hand, etc., so that the bellows on the back side stretches and fits the fingers and the back during refraction. However, on the palm side, the bellows part becomes rough, causing a decrease in adhesion and workability. For example, when using a small instrument, such as a dental reamer, pick the reamer with the thumb (first finger), forefinger (second finger), and middle finger (third finger). If this happens, the back side of each joint of the first finger will sag and the fingertips of the glove will sag, preventing the reamer from being held well. In addition, since the entire glove is provided with the fingertips that reach the back of the joint only at the joint, the glove tends to sag as a whole, and the fit is inferior.

[0007] And, in any of the gloves described in Patent Document 1 and Patent Document 2, only the expansion during the refraction operation of the joint is considered, and the force that does not take into account the sagging of the fingertip portion during use, etc. I got it. In other words, the glove disclosed in these patent documents includes not only the joint part but also the glove having the mouth on the entire glove, and the bellows is extended by the finger wearing the glove, and the fingertip is tensioned. It is not possible to obtain adhesiveness like conventional latex gloves without bellows. More specifically, the glove size with the bellows (for example, the glove size in Patent Document 1 and Patent Document 2) and the glove size without the bellows are the same. If it is smaller than the size selected by the user's hand, the fingertip does not have a pulling force and the fingertip part is left. Also, if the user's hand is larger than the glove size, a strong pulling force will be applied to the entire hand, including the five fingertips, and the problem that the hand will become slack during use will not be improved as before, The number of people who can fit the size is limited. After all, no matter whether the bellows is in the whole glove or not, it was necessary to increase the type of size to provide a glove that fits many people. These are no different from conventional products without bellows.

Problems to be solved by the invention

[0008] The present invention has been made in view of the above-mentioned problems of the prior art, and the object of the present invention is a latex glue that has the same size development as that of the present, and has little fingertips and bumps. Is to provide In other words, since the present invention is frequently used, it does not incur production costs, and provides the same size and excellent operability with good fit for more users, making it safe and reliable. The purpose is to provide latex gloves that can be used efficiently.

Means for solving the problem

[0009] The latex glove according to the present invention includes an extension portion that extends upon insertion of a finger in the finger attachment portion.

The total length of the finger mounting portion is shortened by a length substantially equal to the length of the extension portion to the extent that tension is applied to the fingertip inserted into the finger mounting portion.

[0010] For example, the extending portion can be configured by a bellows portion formed near the finger root portion of the finger mounting portion. In addition, the extension portion is preferably provided only on the first finger, the second finger, and the third finger, which are mainly responsible for work.

[0011] Preferably, a throttling portion is provided between the first finger and the second finger and at a position where the hand wraps around the wrist through the wrist side from the third joint of the fifth finger, and more preferably around the wrist. An aperture is also provided in the vicinity of the position. The invention's effect

[0012] According to the latex glove of the present invention, since the length of the finger attachment portion is shorter than that of conventional gloves, the extension portion provided in the vicinity of the finger root portion of the finger insertion portion extends when attached. The glove is worn with tension applied to the fingertip. Also, the length of the finger mounting part is shorter by the length almost equal to the extension of the extension part.For example, since it is covered with bellows, it corresponds to the length of the finger when a finger is inserted. Only part is extended. Accordingly, the fingertips are not left over, and the ring finger, little finger, back of the hand, etc. that do not have an extension can be used in the same state as existing products. In addition, when a small glove is used, even if the ring finger, little finger, back of the hand, etc. are stretched, such tension does not significantly affect workability. For this reason, latex glove that has the same size type (size development) as the existing latex glove and that is compatible with the fingertips (latex glove with improved operability by promoting fingertip compatibility) is provided to more users.

[0013] A throttling portion is provided at a position where the hand circulates at least between the first finger and the second finger and through the wrist side from the third joint of the fifth finger (little finger). For this reason, this narrowing part pulls the finger insertion side of the extension part, particularly the base part of the second and third fingers, toward the wrist side, which makes it easier to apply tension to the fingertip part. Furthermore, if a throttling part is provided near the position around the wrist, the base of the first finger is pulled toward the wrist. In this way, the additive effect of both makes it easier to apply tension to the fingertip part, and the remainder and blurring of the fingertip can be suppressed. In this way, the throttle portion functions as an anchor that pulls the fingertip in the wrist direction. In other words, the throttle part prevents the entire glove, especially the hem part, from being pulled too far in the fingertip direction, making it easier to apply tension.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments as long as the technical idea of the present invention is satisfied. Fig. 1 is a three-dimensional image of latex glove 1, which is an embodiment of the present invention. Fig. 1 (a) is an imaginary view (image diagram) of glove 1 viewed from the fingertip, and Fig. 1 (b). Is an imaginary view (image diagram) seen from the back of the hand, and Figure 2 is equipped with latex glove 1 shown in Figure 1 Fig. 3 is a perspective view showing the state before and after the latex glove 1 shown in Fig. 1 is installed. Fig. 3 (a) shows the state before installation, and Fig. 3 (b) shows the state after installation ( Time). 4 is a view showing a hand mold 6 used for manufacturing the latex glove 1 shown in FIG. 1. FIG. 4 (a) is a top view thereof, and FIG. 4 (b) is a plan view thereof. . Note that the arm side of hand mold 6 is omitted. Latex glove 1 has the same shape as the left and right, and is drawn assuming that it is attached to the left hand in Fig. 1 (a), and Fig. 2 shows the state that it is attached to the left hand.

The latex glove 1 of the present invention is produced from a stretchable material such as natural latex rubber or synthetic latex rubber. The latex glove 1 of the present invention has a configuration in which the fingertip is tensioned by utilizing the elasticity of the material so that the fingertip can be in close contact with the glove 1. Therefore, if the glove can adopt such a configuration, the configuration of the entire glove is not questioned.However, considering the manufacturing process and the ability to attach to the hand, the elasticity of Glove 1 makes it possible for the entire hand. The most preferred embodiment is application to a glove that is almost in close contact (so-called latex glove in the field). The latex glove 1 of the present invention is a force suitable for a surgical glove.

, Hygiene, biopsy, biology, physics and chemistry, precision machine operation, and other applications where fingertips are important, and other uses such as cooking and washing in general households, cleaning, and gardening It becomes a target.

[0018] As shown in Figs. 1 to 3, each finger of the latex glove 1 of the present invention includes a first finger (parent finger), a second finger (index finger), and a third finger (middle finger). A bellows-like elongated portion (bellows portion) 3 is formed from the root portion, that is, near the base of the finger to such an extent that it does not hang over each finger second joint. The finger attachment portion 2a in which the extension portion 3 is formed is made shorter in length than the conventional latex glove by a length substantially equal to the length that the extension portion 1 extends. When the glove is attached to the hand and the finger is extended, the extension 3 is extended and tension is applied to the fingertip, and the length of the finger attachment 2a is approximately equal to the length of the finger attachment of the conventional latex glove. (Refer to broken line 4 in FIG. 3 (b)). That is, the portion where the overall length of the finger mounting portion 2a is shortened is covered by the bellows.

[0019] The extension amount of each extension section 3 can be determined as appropriate. For example, 5mm, 10mm, etc. . In the case of a glove with an extension of 5 mm, glove 1 of the same size is applied to the user who has a difference in finger length within the range of 5 mm. In the case of Glove 1 with an extension of 10 mm, the same Glove 1 is applied to users who have different finger lengths within the range of 10 mm. In any case, if the glove 1 is worn, the extension 3 is stretched so that the fingertip is tensioned as the finger is inserted, and the tension is always applied to the fingertip. The glove is held in close contact. In addition, the extension part 3 has a force to pull back the fingertip part of the glove 1 due to the restoring force of the material, and the fingertip part that has been stretched by use always comes into close contact with the fingertip. Is suppressed. The effect of this pull-back force eliminates the need to select a conventional latex glove that is one size smaller to match the fingertips as ever. In addition, even when used for a long time, fatigue does not occur and fingertip sagging is reduced. Since the latex glove 1 of the present invention has a structure in which the elongated portion 3 extends, the fingertip can be fitted to a large number of users having the same size and different finger lengths. As described above, the present invention provides a latex glove 1 that has a small size and has a fingertip that fits more people and has a good feeling of use. Note that the extension amount of the first finger, the extension amount of the second finger, and the extension amount of the third finger need not be the same, but rather are set to an extension amount suitable for each finger.

[0020] In the present invention, it is conceivable that the extending portions 3 are also provided on the finger mounting portion 2b of the fourth finger (ring finger) and the finger mounting portion 2b of the fifth finger (little finger), but from the viewpoint of working with the fingertip The force need not have an extension 3 on these fingers. Therefore, comparing the size of the entire glove with the conventional latex glove, as shown in Fig. 10)) and Fig. 3 ( _& ), the fingertip position 4 of the conventional latex glove indicated by the broken line (Fig. Compared with the conventional latex glove, the fingertip position of the finger attachment part 2b of the fourth and fifth fingers is shorter than the finger attachment part 2a of the first, second, and third fingers. It is the same as the fingertip position. Also, the parts other than the first finger, the second finger, and the third finger, for example, the size of the back of the hand, the length in the arm direction, etc. are the same size as the conventional latex glove.

[0021] The position of the extending portion 3 may be any position on the finger mounting portion 2a, but is preferably a position to the extent that the force near the finger root portion is applied to the second joint as described above. If the extension 3 is provided to cover the joint completely, it is the same as the glove described in Patent Documents 1 and 2. Presents the disadvantages. Also, it may be between the first and second joints of the first, second, and third fingers, or between the second and third joints of the second and third fingers. Become.

[0022] The latex glove 1 is manufactured using, for example, a hand mold 6 as shown in FIG.

That is, the hand mold 6 is dipped in an emulsion or suspension of natural latex or synthetic latex, pulled up, and cured on the hand mold 6. The material of the hand mold 6 is not limited as long as it can be manufactured by such a method. Although a symmetrical hand mold 6 may be used, the right and left are generally the same, that is, a glove 1 having no distinction between right and left is produced from one mold 6. As shown in FIG. 4, the hand mold 6 used for manufacturing the latex glove 1 of the present invention corresponds to the extension part 3 (the bellows parts 3a, 3b, 3c) of the first finger, the second finger, and the third finger. In the position, an uneven portion 7 is formed in a ring shape or a spiral shape. The length and height at which the uneven portion 7 is provided are determined in accordance with the elongated portion 3. The size of the hand mold 6 is determined according to the size of the latex glove 1 to be manufactured. However, the manufacturing method of latex glove 1 is not limited to such a manufacturing method.

[0023] The latex glove 1 of the present invention is also set with the same size types as before, typically 5 to 7 sizes. For example, there are five sizes: SS size, S size, M size, L size, and LL size. In this case, each size corresponds to the conventional SS size, S size, M size, L size, and LL size with the extension 3 being stretched. For example, taking the S size as an example, the extension length of the extension portion 3 is equal to the difference between the total length of the SS size finger attachment portion 2a and the total length of the S size finger attachment portion 2a. ,. By adopting such a size configuration, latex gloves 1 that fit perfectly to almost everyone can be provided by arranging the same type of size as the conventional gloves. In other words, if you wear a conventional S size glove and have left your fingertips, you can select the same S size glove. Then, since the extension part 3 of the S size glove extends according to the finger length of the user, there is almost no remainder of the fingertip part. Since the other parts are the same size as the conventional S size, the feeling of use of the other parts remains unchanged. In addition, when the S size is selected as the smaller globe, the user should select the M size glove 1 in the present invention. By using the M size, the 4th and 5th fingers and the back of the hand can be relaxed for a better fit. In addition, the extension part 3 extends with the first, second, and third fingers. The fingertips are perfect.

[0024] In the field where the latex glove 1 is desired to be worn, in most cases, a delicate and precise work is involved, and the work takes a long time. According to the latex glove 1 of the present invention, even a glove having the same size as the conventional one constantly fits a fingertip having a large individual difference. For this reason, the sense of touch is clear, and accurate work is performed safely and efficiently. Moreover, since it can be manufactured by simple processing as in the past, it is possible to suppress an increase in cost. And it is easy to develop the same size as the conventional size development.

Next, a latex glove 1 that is another embodiment of the present invention will be described. FIG. 5 is a three-dimensional image of latex glove 1, which is another embodiment of the present invention. FIG. 5 (a) is an imaginary view (image diagram) and FIG. Fig. 6 is a perspective view showing the state of wearing the latex glove shown in Fig. 5, and Fig. 7 is a hand type 6 used to manufacture latex glove 1 shown in Fig. 5. FIG. 4A is a top view thereof, and FIG. 2B is a plan view thereof. As in the first embodiment, the latex glove 1 has the same shape as the left and right, and is drawn assuming that it is attached to the left hand in FIG. 5 (a), and FIG. 6 is attached to the left hand. Shows the state.

[0026] This latex glove 1 has constricted portions 5 at two locations. One throttle part 5 is in a position that goes around the wrist, and the remaining one throttle part 5 is a position that goes around the palm of the hand, more specifically, the thumb (first finger) and the index finger (first). 2) and around the third joint of the little finger (fifth finger) through the wrist. These throttle portions 5 further enhance the fit of the latex glove 1. That is, the aperture 5 performs a so-called anchor function. The diaphragm 5 located around the hand plays a role of pulling to the back side of the hand so that the base part of the second and third fingers is not displaced in the fingertip direction. For this reason, the base part of the second and third fingers is pulled toward the back of the hand (palm) side, and tension is more easily applied to the fingertip part. In addition, the aperture near the position around the wrist serves to pull the base of the first finger toward the back of the hand so that it does not shift in the fingertip direction. For this reason, the base portion of the first finger is pulled toward the back of the hand, and tension is more easily applied to the fingertip portion. In this manner, the additive effect of the two narrowed portions 5 makes it easier to apply tension to the fingertip portion, and the remainder of the fingertip and looseness are suppressed. In other words, the narrowed portion 5 prevents the entire glove, particularly the hem portion, from being pulled too much in the fingertip direction, and makes it easier to apply tension. In addition, when working with Glove 1, the fingertips and back of the hand of the Glove 1 will sag due to bending and stretching of the fingers and opening of the hand. The diaphragm 5 also functions to reduce this sagging. As a result, an appropriate tension is constantly applied to the fingertip, and the fingertip can be used for a long time in a fitted state. Although the purpose can be sufficiently achieved only by the throttle part 5 at the position of circling the hand, it is preferable that the throttle part 5 is also provided around the wrist in consideration of pulling of the first finger.

[0027] When the diaphragm portion 5 is greatly narrowed, a feeling of pressure (feeling of being pinched) received by the back of the hand at the time of wearing becomes strong, resulting in a decrease in workability. For this reason, it is preferable to provide the throttle portion 5 with reference to the extent that the fingertip portion of the groove 1 does not stretch or contract when the finger is bent and stretched. In addition, although the narrowed portion 5 shown in each drawing is manufactured to have a slightly wide shape, the width is not limited as long as the above function is achieved. However, if the width of the narrowed portion 5 is small, for example, if it is close to a linear shape like a rubber band, the force to narrow it will be applied locally and the feeling of pressure will be too strong, so it will not become extremely narrow. It is preferable to do so. In addition, since the diaphragm 5 is provided, the glove comes into close contact with the palm. For this reason, the effect of reducing the itchiness of the glove 1 that can be formed in the palm of the hand when holding the hand can be expected.

[0028] The glove 1 provided with the narrowed portion 5 is also produced by, for example, immersing a hand mold 6 as shown in FIG. 7 in natural latex or synthetic latex emulsion and curing it on the hand mold 6. . The hand mold 6 is provided with a recess 8 for forming the throttle portion 5, and the throttle portion 5 is easily provided in the latex glove 1 by the recess 8. Of course, a pair of left and right gloves 1 may be made by making a symmetrical hand mold 6, but usually the left and right same type, that is, a glove 1 with no distinction between right and left is produced.

Industrial applicability

[0029] According to the present invention, there is provided a latex glove that fits more users with fewer sizes. Also provided is a latex glove that can be worn for a long time with a small amount of slack during use.
