Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pant-type undergarment in which a lift-and-hold portion can be appropriately arranged according to a wearer's condition, can be easily attached and detached, and can be suitably used.

[0002]

2. Description of the Related Art Pants-type underwear has a waist opening and a pair of leg openings. The wearer pulls up from the wearer's toes to the waist and wears it while grasping the waist-opening with the fingertips. However, when the fingertips are clumsy or the elderly or sick people who have extremely weak gripping power with their fingertips wear pants-type underwear by themselves, grasp the waist opening of the pants-type underwear and pull it up sufficiently. Was difficult. In addition, it is necessary to pull up with one hand, especially for a person with paralysis in the half of the body, and it is difficult to grasp with conventional pants-type underwear, and it is difficult to pull up sufficiently.

Therefore, a method of connecting a loop-shaped gripping portion to the waist circumference side of underpants-type underwear is disclosed in Japanese Utility Model Laid-Open No. 6-11720, in which a protruding gripping portion is formed in the overlapping region of the front and rear bodies. Japanese Utility Model Laid-Open No. 6-50623 discloses a method in which a finger-hanging member is fixedly provided on the outer surface of the waist portion in Japanese Patent Application Laid-Open No. 11-43801. However, in any case, since the finger rest or the gripping part is fixed to the underpants-type underwear,
There was a problem that it was an obstacle after pulling up the pants-type underwear. Further, since the finger rest or the gripping part is fixed to a specific area of the underpants-type underwear, it is not always within the reach of the wearer and may not be used depending on the wearer's situation.

On the other hand, there is a method of forming an opening in the pants-type underwear in the circumferential direction around the waist so that a finger can be hung on the underwear.
No. 337300, Japanese Patent Laid-Open No. 11-21702,
It is disclosed in JP-A-11-104180. However, in any of the methods, it is necessary to attach a sheet for forming the finger hook portion as a separate body, or to fold the sheet back to form the finger hook portion, which means that many extra members are used, There are problems that the cost becomes high, the manufacturing becomes complicated, and the manufacturing cost becomes high.
Also, as in the previous example, since the finger-holding part is fixed and formed in a specific area of the underpants-type underwear, it is not always within the reach of the wearer, and It was not always formed at an angle where force could be applied, and it could not be used depending on the condition of the wearer.

[0005]

SUMMARY OF THE INVENTION In view of such a situation, the present inventors have found that in a pants-type underwear having a waist-opening and a pair of leg-openings, a slip is needed to facilitate pulling up the pants-type underwear. We came to the conclusion that a lifting grip is necessary. In addition, it was concluded that the condition of the wearer is different for each person, and it is necessary to form the gripping portion at a place suitable for each person. On the other hand, after pulling up the underpants-type underwear, the holding part becomes an obstacle, so it was concluded that it must be removable. Furthermore, it was concluded that in order to provide an inexpensive underpants-type underwear, it is possible to easily manufacture the underpants-type underwear, and it is necessary to inexpensively form the gripping portion which is not the basic configuration of the underpants-type underwear.

The object of the present invention is to appropriately dispose the slide-and-holding portion at a necessary position according to the wearer's condition, to remove it when it is not necessary, to easily attach and detach, and to use it at a low cost. The purpose is to provide pants-type underwear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pant-type underwear which is an embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these. FIG. 1 is a perspective view of pants-type underwear. In FIG. 1, the underpants-type undergarment 1 has a waist-opening 2 and a pair of legs-around openings 3. The waistline has a longitudinal line 4 and a width-direction line 5 of the underpants.
Are formed. Further, a pair of loop-shaped gripping portions 6 that are detachable from the underpants-type underwear are arranged.

Although a pair of gripping portions 6 are arranged in the drawing, the number of gripping portions 6 may be one or three or more. The number of gripping portions 6 is not particularly limited, because it is preferable that the gripping portion 6 be provided in a necessary number in a necessary position for the wearer to pull up the pant-type underwear 1. Further, in the drawings, the holding portions 6 are shown to have the same shape on the left and right sides, but they do not have to have the same shape, and the size and shape may be different according to the place of arrangement. When it is necessary to pull up the underpants-type underwear with one hand, such as a hemiplegic wearer, it is difficult to reach the paralysis side, so the gripping part 6 on the paralysis side is preferably large. The shape of the grip portion 6 does not have to be looped, and may be a finger hook portion or a piece of cloth formed of a material that prevents the fingers from slipping when the fingers are hooked, and is not particularly limited. The grip portion 6 preferably has a higher tensile strength than the outer material of the pants-type undergarment 1. Holding part 6
May be a non-stretchable material, but may be a stretchable material and is not particularly limited.

In the drawing, the longitudinal line 4 and the width line 5 of the underpants-type underwear are formed, but only one of them may be formed. Further, although the widths of the lines are the same in the drawings, it is preferable to form the lines with different widths, colors, and the like. The wearer can arrange the gripping portion 6 at a necessary position with the line as a mark, and it is not necessary to search for the optimum arrangement position of the gripping portion 6 each time the pants-type undergarment 1 is attached and detached. The line does not have to be formed by a solid line, but a broken line, a dotted line,
You may form with various marks. Also, preferably, a number or the like is shown on the line so that the position can be easily understood. Although only the front body part of the underpants-type underwear is shown in the drawing, a line may be similarly formed on the back body. Depending on the wearer, it may be better to arrange the gripping portion 6 on the back side. The line may be printed on the pants-type underwear 1 itself,
In the case of a disposable pants-type diaper, printing may be performed on a cover sheet or a liquid impermeable back sheet. Further, when the members of the surface fastener are arranged, lines may be printed in advance on the surface fastener member. Further, the printing may be performed by assembling what has been printed on various materials in advance, but the printing may be performed by an ink jet or the like in the process of assembling the underpants-type undergarment 1 and is not particularly limited.

The method of joining the grip portion 6 and the underpants-type undergarment 1 is as follows.
Mechanical fastening systems such as hook-and-loop fasteners are preferred. In this case, it is preferable to dispose the convex material on the grip portion 6 and the concave material on the underpants-type undergarment 1, but the converse material may be reversed and is not particularly limited. Further, it suffices that the grip portion 6 and the underpants-type undergarment 1 be detachably joined, and particularly when the pants-type undergarment portion 1 and the gripping portion 6 are made of a convex material that is easily joined, a concave material is particularly preferable. Need not be placed on the other side. It is preferable that the joining portion 6 of the underpants-type undergarment 1 is joined to the entire holding portion, but depending on the wearer, it may be sufficient if the joining portion is provided in a very small portion, and the holding portion 6 is held only partially. You may provide the junction part 6. It is cheaper than providing the gripping portion 6 joining portion on the entire underpants-type underwear 1, and it can be provided at low cost to a wearer who only needs a joining portion on a very small portion. In this case, only around the waist and the waist opening 2
There is no particular limitation, depending on the wearer's situation, such as only the side portion around the waist and around the waist.

The shearing force between the underpants-type underwear 1 and the holding part 6 is
It is preferable that the underpants-type underwear is high in the upper direction, which is the pulling-up direction, and is easily formed in the lower direction. Therefore, it is preferable that the pin of the convex portion is arranged so as to be inclined upward in a state where the pants member and the grip portion 6 are joined.

Further, the means for connecting the underpants-type undergarment 1 and the grip portion 6 may be means used for general clothes such as buttons and fock. In the case of a button or a fock, a button or a fock that serves as a protrusion may be arranged on the underpants-type undergarment 1, but may be arranged on the holding part 6 and is not particularly limited. Rather than pulling down the underpants-type undergarment 1 and attaching / detaching the gripping section 6 each time the puller is pulled up, the wearer may arrange the gripping sections 6 in a size and number suitable for his / her suitable position in advance. There is also a desire to use the gripping part 6 without removing it. For such a wearer, a method of arranging a button or a flock on the underpants-type undergarment 1 and joining the grip portion 6 to the button or the fock at the optimum position is also effective. Further, the pants-type underwear 1 may be formed with a notched portion or the like to which a button or a hook can be joined, and the gripping portion 6 with the button or the hook may be joined. In this case, it is preferable that the cut part of the underpants-type underwear 1 is reinforced so as not to tear, and the material is made of a material such that the cut part does not expose the skin.
It may overlap.

The disposable pants-type diaper in this embodiment may be any known disposable pants-type diaper and is not particularly limited. Even in the case of disposable pants-type diapers, by making the gripping portion 6 removable, it is not always necessary to discard the pants-type diaper together, and by repeatedly using only the gripping portion 6, It is possible to inexpensively provide a disposable pants-type diaper in which a gripping portion for lifting up is arranged.

The embodiment is the underpants-type undergarment 1, but the present invention may be any underpants-type underwear, such as shorts, light incontinence shorts, sanitary shorts, disposable pants-type diapers. It is effective because it can be applied to any type of underwear.
