Description

  The present invention relates to a pad holder used in combination with an absorbent pad that absorbs bodily fluids such as urine and menstrual blood. More specifically, the present invention relates to a pad holder that can improve the fit of the absorbent pad to the crotch and improve the leak-proof property.

  Conventionally, in hospitals, nursing homes, home care sites, etc., the pad holder is worn with the absorbent pad attached to the skin facing surface of the crotch part of the pad holder, making it difficult for the absorbent pad to absorb the liquid. In this case, only the absorbent pad is replaced with a new one, and the pad holder is reused after washing as necessary. Thereby, compared with the case where a disposable diaper etc. are used, reduction of the quantity and cost of garbage can be aimed at.

  The pad holder has a front body, a back body, and a crotch portion positioned between the two, the front body and the back body are each formed of an elastic sheet, and a waist opening and a pair of leg openings It is known that an absorbent pad is attached to the lower crotch and is worn. Among such pad holders, in particular, the trunks type (boxer pants type) pad holder, that is, the type of pad holder in which the opening peripheral edge of the leg opening is positioned below the crotch when worn is the leg opening. Compared to so-called high leg type (brief pants type) pad holders where the peripheral edge of the opening is close to the waist opening, the absorbent pad is less likely to be displaced, and the pad retainability is high. . In such a trunks-type pad holder, leg elastic members are provided at the opening peripheral portions of the pair of leg openings for the purpose of preventing the absorbent pad attached to the crotch part of the pad holder from protruding to the outside. The thigh gathers are arranged so that the thigh gathers tighten the wearer's thighs (see, for example, Patent Document 1).

  However, the above-described conventional trunks-type pad holder has a problem in leak-proof property because the fit of the absorbent pad to the crotch portion of the body is not sufficient. That is, when the conventional trunks-type pad holder is worn, when the leg is held through the leg openings as usual, the waist of the pad holder is picked up and the whole is pulled up. A gather (an elastic member of a leg part) is caught below a place where it should be originally located in the thigh part of the body. And when it is further pulled up in this state, the entire pad holder is stretched in the vertical direction while the thigh gathers are caught in the middle due to the action of the elastic sheet constituting the pad holder, and as a result, the waist portion is in the desired position. However, the crotch part is not pulled up sufficiently, and the absorbent pad attached to the crotch part is used without being in close contact with the crotch part of the body. It was.

The waist elastic member 51 is fixed to the front body 2 and the back body 3 (the stretchable sheet 10) by sewing or pasting using an adhesive or the like. As the waist elastic member 51, for example, a stretchable woven fabric made of polyurethane fiber, a synthetic rubber sheet, a natural rubber sheet, or the like is used.

  A leg elastic member 61 is annularly arranged in an extended state at the opening peripheral edge of the leg opening 6, thereby forming a thigh gather. The leg elastic member 61 is fixed to the front body 2 and the back body 3 (the stretchable sheet 10) by sewing or pasting using an adhesive or the like. As the leg elastic member 61, the same elastic member as the waist elastic member 51 described above can be used, and the elastic elastic member may be the same or different between the leg elastic member 61 and the waist elastic member 51. Also good.

  In the present invention, the thigh gathers (leg elastic members) are located at the same height as the crotch or below the crotch when the pad holder is worn. With such a configuration, it is possible to effectively prevent the absorption pad attached to the crotch part from protruding to the outside and improve the leakage prevention effect. In particular, as in the present embodiment, it is preferable that the thigh gathers are located below the crotch in terms of preventing the absorption pad from protruding. The pad holder 1 of the present embodiment is a so-called trunks type (boxer pants type) pad holder, and the wearer is arranged so that the front body 2 and the back body 3 are aligned as shown in FIGS. 1 and 2. The thigh gathers (leg part elastic member 61) are located below the crotch part 4 when the folding lines 1a and 1a along the waist side are folded in two. The shortest distance H between the lowermost part 4a of the crotch part 4 and the lowermost part of the thigh gathers (leg part elastic member 61) is preferably 0 to 70 mm, more preferably 10 to 50 mm. The lowermost part means a part that is located at the lowest position when the pad holder is worn in the part (thigh gather, crotch part, etc.). The shortest distance H is measured when the pad holder 1 is in an unstretched (non-wearing) natural state.

In addition, when the pad holder 1 is folded in two at the folding lines 1a and 1a along the wearer's waist side so that the front body 2 and the back body 3 are combined as shown in FIG. 1 and FIG. The shortest distance L1 (height) between the opening peripheral edge of the waist opening 5 (the uppermost part of the waist opening 5) and the opening peripheral part of the leg opening 6 (lowermost part of the leg opening 6) is preferably 160. 360 mm, more preferably 190-330 mm, and the shortest distance L2 (rise height) between the opening peripheral edge of the waist opening 5 and the lowermost part 4a of the crotch part 4 is preferably 160-320 mm, Preferably it is 180-300 mm.
The ratio between L1 and L2 is preferably in the range of L1 / L2 = 1.00 to 1.45, and more preferably in the range of L1 / L2 = 1.05 to 1.30.
The shortest distance L1 (height) and the shortest distance L2 (rise height) are both measured when the pad holder 1 is in an unstretched (non-wearing) natural state.

Each of the front body 2, the back body 3, and the crotch part 4 is formed from the stretchable sheet 10 as described above, whereby the pad holder 1 has the vertical direction L as the vertical direction when worn, and the vertical It can be expanded and contracted along each lateral direction S orthogonal to the direction L. The elongation at the time of 1.0 N / 50 mm load in the longitudinal direction L of the pad holder 1 of the elastic sheet 10 is 30 to 120%, preferably 35 to 90%, and the lateral direction S of the pad holder 1 of the elastic sheet 10 The elongation at a load of 1.0 N / 50 mm is 25 to 90%, preferably 35 to 80%. Since the elongation in the product longitudinal direction L and the product transverse direction S of the stretchable sheet 10, which is the main forming material of the pad holder 1, is within the above range, the pad holder can be easily lifted and lowered during attachment / detachment. , Handling is improved.
The said elongation of the elastic sheet 10 is measured as follows.

<Method for measuring elongation of elastic sheet>
A rectangular shape having a size of 150 mm in the vertical direction L and 50 mm in the horizontal direction S perpendicular to the vertical direction L is cut out from the pad holder to be measured, and this cut out rectangular shape is used as a measurement sample. The measurement sample is cut out so as not to include the waist elastic member 51 and the leg elastic member 61. In addition, when the pad holder is formed by sewing each part constituting the pad holder, the measurement sample is cut out so as not to include the stitched portion (if the stitched portion must be included, the stitched portion should be Cut out the measurement sample so as to include a small amount, or cut out the measurement sample so that the stitched portion is located in the chuck portion (25 mm before and after the measurement sample). When a measurement sample having a sufficient size cannot be cut out from the pad holder to be measured, the size of the chuck portion (a portion of 25 mm before and after the measurement sample) may be reduced.
The measurement sample is attached to the chuck of the tensile tester so that the longitudinal direction L is the tensile direction. The distance between chucks is 100 mm. Pull the measurement sample at 300 mm / min and use the length when the measurement sample is stretched when the load value is 1.0 N (the length of the measurement sample located between the chucks when stretched), The elongation at a load of 1.0 N / 50 mm is obtained.
Elongation (%) = [(Length when stretched (mm) −100 (mm)) / 100 (mm)] × 100
Further, a rectangular shape having a size of 50 mm in the vertical direction L and 150 mm in the horizontal direction S is cut out from the pad holder and used as a measurement sample, and the measurement sample is pulled so that the horizontal direction S is the tensile direction. Attached to the chuck of the testing machine, the elongation at 1.0 N / 50 mm load in the lateral direction S is determined by the same procedure as above.

  As the stretchable sheet 10, for example, a net-like fabric knitted with synthetic fibers or natural fibers can be used.

  In the front body 2 of the pad holder 1, the elastic elastic members 71, 71 are arranged in an extended state along the wearer's ridge, thereby forming a ridge gather. The groin is the part of the base of the foot that is the joint between the human torso and the lower limb, that is, the boundary between the abdomen and the foot, and exists in a symmetrical position across the crotch. Accordingly, the elastic members 71, 71 are also arranged at symmetrical positions across the virtual line P1 that bisects the front body 2 in the lateral direction S when not worn, so as to follow the left and right foot respectively. Has been. The right throat elastic member 71 and the left heel elastic member 71 are independent of each other and are not connected. Since there is a sock gather, the sock gather will preferentially fit to the sock part, so there is a problem with this type of pad holder between the crotch part of the pad holder and the crotch part of the body. The poor adhesion is eliminated, the fit of the absorbent pad attached to the crotch part to the crotch part is improved, and an excellent liquid leakage preventing effect can be obtained.

  Further description will be given on the elastic part 71 of the elastic part (the elastic gather). The elastic part 71 of the elastic part is folded along the wearer's waist so that the front body 2 and the back part 3 are aligned with the pad holder 1. In the state folded in two by the curves 1a and 1a (the state shown in FIGS. 1 and 2), it extends continuously from the vicinity of the lowermost part 4a of the crotch part 4 to the folding line 1a along the wearer's ridge part. It is arranged in. More specifically, the bottom elastic member 71 has a lowermost portion 71a positioned in the vicinity of the lowermost portion 4a of the crotch portion 4, and an uppermost portion 71b above the lowermost portion 71a and the front body. 2 is arranged below the virtual line P2 that bisects 2 in the vertical direction L. The shortest distance L3 between the lowest part 71a of the bottom elastic member 71 and the lowest part 4a of the crotch part 4 is preferably 0 to 50 mm, more preferably 20 to 50 mm. The shortest distance L4 between the uppermost part 71b of the bottom elastic member 71 and the imaginary line P2 is preferably 0 to 100 mm, more preferably 30 to 80 mm. Moreover, the shortest distance S1 between the lowest part 71a of the ridge part elastic member 71 and the virtual line P1 becomes like this. Preferably it is 0-70 mm, More preferably, it is 20-50 mm. The shortest distance S2 between the uppermost portion 71b of the ridge elastic member 71 and the folding line 1a closest to the ridge elastic member 71 is preferably 0 to 30 mm, more preferably 0 to 10 mm (this embodiment). In the embodiment, the shortest distance S2 is 0 mm, and S2 is not shown in FIG. 1). The shortest distances L3, L4, S1, and S2 are all measured when the pad holder 1 is in an unstretched (non-wearing) natural state.

The ridge elastic member 71 is fixed by being sewn to the front body 2 (the stretchable sheet 10) or attached by an adhesive means such as an adhesive. As the elastic part elastic member 71, the same thing as the waist elastic member 51 mentioned above can be used.
The length of the bottom elastic member 71 is preferably 100 to 200 mm, more preferably 120 to 180 mm, and the width is preferably 1 to 30 mm, more preferably 3 to 15 mm.

The contraction stress (A) at the time of 1.5 times expansion of the elastic part 71 of the ridge part is from the viewpoint of making the above-mentioned effects (improvement of fitability of the crotch part, leakage prevention effect) more reliable. The leg elastic member 61 is preferably larger than the contraction stress (B) when stretched 1.5 times. Preferably it is A / B = 1.2-4.0, More preferably, it is A / B = 1.5-3.0.

<Measurement method of shrinkage stress when elastic member is stretched 1.5 times>
After cutting the boundary part (folding curve 1a) between the front body 2 and the back body 3 and putting the pad holder 1 in the unfolded state, the elastic member to be measured is cut out to obtain a measurement sample. When the measurement sample includes an elastic member other than the measurement target elastic member, the elastic member other than the measurement target is removed or cut so that the contraction stress of the elastic member other than the measurement target does not appear.
The measurement sample is placed on a horizontal surface so that the outer surface of the measurement sample on the skin contact surface side is in contact with the horizontal surface. (= The width direction of the pad holder) The length of the line connecting the middle points in the longitudinal direction of the upper edge and the lower edge at both side edges is measured, and the value obtained by subtracting 20 mm from this measured value is taken as the natural length.
Then, this measurement sample is fixed between chucks of a Tensilon tensile tester [Orientec Co., Ltd., RTC-1150] (the region that enters the 10 mm width direction inside from both ends in the width direction of the measurement sample is fastened with the chuck. ) The load at that time is zero. Thereafter, the measurement sample is stretched at a tensile speed of 300 mm / min in the same direction as the width direction of the pad holder until the natural length becomes 1.5 times the natural length. And

L9 and L10 may be the same or different. The shortest distances L9 and L10 are measured when the pad holder 1 is in an unstretched (non-wearing) natural state.

  The elastic member 91 is covered with the crotch cloth 11 at the front body 2 and the back body 3 respectively, specifically at the center in the longitudinal direction. That is, the elastic member 91 is disposed so as to cross the non-skin facing surface side of the vertically long crotch cloth 11 along the width direction orthogonal to the longitudinal direction of the crotch cloth 11. The portion of the elastic member 91 that is covered with the crotch cloth 11 and the crotch cloth 11 may be joined or may not be joined. When joining between these, sewing, an adhesive agent, etc. can be used as a joining means. A portion of the elastic member 91 that is covered with the crotch cloth 11 and the crotch cloth 11 are preferably joined to improve the adhesion of the absorbent pad attached to the pad holder 1 to the body.

The elastic member 91 is fixed by being sewn on the stretchable sheet 10 forming the front body 2 and the back body 3 or by being attached by an adhesive means such as an adhesive. As the elastic member 91, the thing similar to the waist part elastic member 51 mentioned above can be used.
The length of the elastic member 91 is preferably 100 to 350 mm, more preferably 150 to 250 mm, and the width is preferably 1 to 30 mm, more preferably 3 to 15 mm.

The contraction stress (D) when the elastic member 91 is stretched 1.5 times is preferably 15 to 150 cN, and more preferably 20 to 100 cN. This shrinkage stress (D) is measured by the above-described shrinkage stress measurement method.
The shrinkage stress (D) includes the shrinkage stress when the heel elastic member 71 is stretched 1.5 times or the shrinkage stress (A) when the hip elastic member 81 is 1.5 times stretched, and the leg portion. The relationship between the elastic member 61 and the contraction stress (B) when the elastic member 61 is stretched by 1.5 times is adjusted so that A>B> D, to the crotch part of the body of the absorbent pad attached to the pad holder 1 This is preferable in terms of the fit and ease of lifting the pad holder 1.

  The pad holder 1 configured as described above is worn and used in the same manner as a conventional pad holder of this type. First, an absorption pad is attached on the skin facing surface of the crotch 4 (skin facing surface of the crotch cloth 11), and then the legs are inserted through the pair of leg openings 6 and 6. As the absorbent pad, those applicable to this type of pad holder can be used without particular limitation. For example, sanitary napkins, urine-absorbing pads, light incontinence pads and the like can be used. And the pad holder 1 is pulled up from this state, and the opening peripheral part of the waist opening part 5 is closely_contact | adhered to a wearer's waist part.

  At this time, the pad holder 1 is smoothly pulled up by the action of the elastic sheet 10, and the throat gather (the heel elastic member 71) fits to the garment of the wearer. The absorbent pad attached to the portion 4 is in close contact with the crotch portion, and this close contact state is maintained. As a result, the original performance of the absorbent pad is fully utilized, and liquid leakage due to the displacement of the absorbent pad is effectively prevented.

In particular, as in the present embodiment, a buttock gather (an buttock elastic member 81) is arranged in addition to the sock gather, and on the skin facing surface side of the crotch part 4, it is inferior in elasticity to the elastic sheet 10. A crotch cloth 11 having a waterproof property, a part of each of the spacer gathers and the buttocks gathers is covered with the crotch cloth 11, and the crotch cloth covering the part and the part. When the gaps are joined to each other, the fit of the pad holder 1 with respect to the base of the foot including the groin is remarkably improved, so that the fit of the crotch part 4 to the crotch part is particularly excellent. This provides a more excellent liquid leakage prevention effect.
Further, the pad fit gather (elastic member 91) is formed, so that the fit of the pad holder 1 to the body part located above the base of the foot including the heel portion is improved. 1 The overall fit to the body is further improved.

  When it becomes difficult for the absorbent pad attached to the pad holder 1 of the present embodiment to absorb the liquid by use, it is only necessary to replace the absorbent pad with a new one. After the pad holder 1 is washed as necessary Can be reused. Therefore, by using the pad holder 1 of the present embodiment, the amount of dust can be minimized, and the cost can be reduced.

As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment.
For example, the sock gather (sock part elastic member 71) may be formed along the sock part, and is not limited to the arc shape as in the above embodiment, but may be a straight line. Further, the buttocks gather (the buttocks elastic member 81) only needs to be formed along the buttocks (the lower side of the buttocks), and is not limited to the arc shape as in the above embodiment, but may be linear.
Moreover, in the said embodiment, although the sock gather and the buttocks gather were connected and united by the waist side part (folding curve 1a), both do not need to be connected.

  Moreover, in the said embodiment, the front body 2, the back body 3, and the crotch 4 are comprised by circular knitting so that there may be no joining part, and the pad holder 1 is one continuous elastic sheet. 10 is substantially formed, but instead of such a configuration, each part of the front body 2, the back body 3 and the crotch part 4 is stitched to form the pad holder 1, and both ends of each part are formed. The peripheral edge may be sewn.

It is the front (front body side) figure which showed one Embodiment of the pad holder of this invention in the two-fold state in which the front body and the back body are united. It is a back surface (rear body side) view of the pad holder in a folded state shown in FIG. FIG. 2 is a perspective view showing the pad holder shown in FIG. 1 in a three-dimensional state.
