Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposable diaper, and more particularly, to a pants-type diaper having excellent wearability and a method for wearing the same.
[0002]
[Prior art]
Conventionally, disposable diapers have been used as infant diapers and the like. The main function of such a disposable diaper is to hold the excrement such as urine accurately so as not to leak outside. It is also extremely important that the wearability is excellent so that the wearer can wear it smoothly when wearing a diaper.
[0003]
As shown in FIG. 6 (A), the conventional underpants type diaper has a waist opening c and both leg openings by joining (fixing) the front body a and the back body b to each other at both sides thereof. d is formed and formed into a three-dimensional shape.
And the waist opening part c is provided with the elastic contraction member e, and the waist flap f which has a stretching property is formed.
As a result, when the diaper is worn, the holding power to the waist of the body is increased, and it is difficult to come off even after wearing.
[0004]
Furthermore, some pants-type diapers have a high friction member g on the inner surface of the waist opening c in order to further increase the holding force on the waist and reliably prevent slippage during wearing [Fig. 6 (B)].
Normally, as shown in FIG. 7, the pants-type diaper is first worn by first grasping both side parts of the pant-type diaper to widen the waist opening c, and put the legs through the waist opening c and take out from the leg opening d. In this manner (see FIG. 7A), the diaper is pulled up as it is, and the waist opening c is positioned on the waist.
However, when the pants-type diaper having the high friction member g on the inner surface of the waist opening c is worn, there is a problem in a normal wearing method.
[0005]
This is because, when pulling up the pant-type diaper, the high friction member g provided on the inner surface of the waist opening c comes into contact with the skin surface of the body, and the high friction member g becomes a resistance [FIG. 7 (B)].
As a result, if it is forcibly pulled up, there is a risk of damaging the skin, and due to the difference in resistance, unevenness is caused in the pulled-up state, and the waist line WL of the pants-type diaper is not aligned (see FIG. 7C). .
[0006]
[Problems to be solved by the invention]
The present invention is intended to solve the above problems.
That is, the objective of this invention is providing the underpants type diaper which can be mounted | worn smoothly without a feeling of resistance to a body.
Moreover, it is providing the mounting method of the underpants type diaper.
[0007]
[Means for Solving the Problems]
Thus, the present inventors have conducted extensive research based on such a background, and as a result, the waist portion of the pant-type diaper is folded outward by a predetermined width to temporarily hold the high friction member. As a result, the present invention has been completed by finding the point where it becomes a position that does not contact the skin surface of the body as much as possible.
[0008]
That is, the present invention comprises (1) a front body, a back body, and a crotch portion positioned between the two, and at least a crotch portion is provided with an absorber, and the front body and the back body are joined to each other at both sides. Thus, a waist diaper in which a waist opening and both leg openings are formed, the waist opening is provided with an elastic contraction member and a waist flap having a high friction member on its inner surface. Therefore, the waist flap folds outwards by a certain width and exists in a temporarily folded waist pants-type diaper.
Thus, since the waist flap is folded back outward by a certain width and is in a temporary holding state, there is little resistance to the body (skin surface) when wearing, and as a result, smooth wearing is possible. At the same time, it does not hurt the skin, so it is especially suitable for infants with soft skin.
[0009]
And (2), the folded waist flap exists in the waist folded underpants type diaper temporarily fixed in the both sides of the front body or the back body in order to stabilize the temporary holding state.
When temporarily fixed in this way, a stable maintained state of the folded portion can be ensured.
[0010]
And (3), the folded back waist flap exists in the waist folded underpants type diaper which is temporarily fixed by embossing.
Thus, when temporarily fixed by embossing, the stable maintenance state of a folding | returning part is securable according to the effect.
[0011]
And (4) exists in the waist folded underpants type diaper which gives the heat seal for stabilizing the temporary holding state to the both sides of the folded waist flap.
Thus, when temporarily fixed by heat sealing, the stable maintenance state of the folding | returning part is securable.
[0012]
And (5), the folded waist flap exists in the waist folded pants type diaper provided so that an absorber may not reach.
Since the absorber does not reach in this way, the area where the material on the inner surface of the diaper is exposed to the outside and exposed to the outside air can be suppressed as much as possible, which is extremely hygienic.
[0013]
(6) A disposal fastening tape having one end fixed is provided on the outer surface side of the front body or the back body, and the free end of the disposal fastening tape is covered with a folded waist flap. The waist-folded pants-type diaper is.
In this way, when the picked-up portion is covered with the folded back flap 1, the unraveling is prevented.
[0015]
The present invention can also adopt a pants-type diaper having a configuration in which two or more selected from the above 1 to 6 are combined as long as the purpose is met.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on the drawings with specific embodiments.
The main feature of the pants-type diaper of the present invention is that the waist flap is folded outward by a predetermined width to be in a temporary holding state.
[0017]
FIG. 1 is a perspective view of a pants-type diaper P according to an embodiment of the present invention.
[0018]
FIG. 2 is a front view of the pants-type diaper P shown in FIG. 1 (A) and a cross-sectional view taken along line YY of the front view (A).
FIG. 3 is an enlarged view of a main part of FIG.
[0019]
The pants-type diaper P includes a front body A, a back body C, and a crotch B positioned between the two.
By joining the front body A and the back body C to each other at both sides, a waist opening D and both leg openings E are formed, and a three-dimensional pant diaper P is formed.
[0020]
Moreover, this underpants type diaper P is provided with an absorbent body 2 at least in the crotch part B, in this embodiment, in the central region over the front body A, the back body C, and the crotch part B (see FIG. 2).
The absorber 2 usually has a structure in which a defibrated pulp and a superabsorbent polymer are wrapped with a water-permeable tissue. The absorber 2 is interposed between the liquid-permeable top sheet 3 and the liquid-impermeable back sheet 4 (see FIG. 3).
[0021]
And the barrier cuff which is not illustrated in the longitudinal direction is formed in the inner side of the diaper P in the both sides of the part with which the absorber 2 was equipped, ie, the front body A, the back body C, and the crotch part B. This barrier cuff is made of a liquid-impermeable sheet, and it is possible to stand up in a gathered shape by installing an elastic elastic member (for example, made of natural rubber, synthetic rubber, etc.) on the standing free edge. is there.
[0022]
The barrier cuff prevents liquid such as urine absorbed by the absorbent body 2 from leaking outward from the crotch due to this elastic force. That is, when a pants-type diaper is worn, the barrier cuff stands by its own stretching force to form a standing wall, and can reliably prevent urine and the like from leaking outward.
[0023]
Now, pay attention to the waist opening D of the pants-type diaper P.
The waist opening D has a constant width region (located a certain distance below the upper end) as a waist flap 1. Moreover, it is preferable that the above-mentioned absorber 2 does not reach the waist flap 1.
[0024]
The waist flap 1 is provided with elasticity by attaching an elastic contraction member S between a liquid-permeable top sheet 3 and a liquid-impermeable back sheet 4.
[0025]
A high friction member 11 is provided on the inner surface of the waist flap 1. As the highly frictional member 11, typically, an elastomer mainly composed of polyethylene, urethane foam or the like can be preferably used, and has a high frictional force about 2 to 5 times that of a normal diaper material from the viewpoint of holding power. A thing is adopted and a sheet-like thing is adopted.
[0026]
The portion of the waist flap 1 where the high-friction member 11 is provided is folded outward by a predetermined width and is temporarily held.
In this case, the folded width L of the folded portion M may be larger than the portion where the high friction member 11 is provided, and includes at least the portion where the high friction member 11 is provided. In this temporary holding state, it will be understood that the waist opening D is doubled. In this case, the highly frictional member 11 is exposed to the outside without contacting the skin surface. The folded back flap 1 is preferably maintained as much as possible until the waist opening is positioned at the waist of the wearer.
[0027]
Therefore, it is preferable that the folded back waist flap 1 is temporarily fixed at both sides of the front body A or the back body B in order to stabilize the folded state.
As this temporary fixing, heat sealing or embossing can be employed.
In addition, these processes for stabilization are selectively performed if necessary.
[0028]
By the way, the pants-type diaper P which is a disposable diaper is rolled up and made small after use and discarded. As a member for fixing the rolled-up state, a disposal fastening tape 5 having one end fixed to the outer surface side of the front body or the back body of a normal diaper is provided. The other end of the disposal fastening tape 5 is a folded free end, and the free end has a picking portion 51 (see FIG. 3). However, the picking-out part 51 is often located below the waist flap 1 and is easily unraveled and detached after packing the pants-type diaper P during transportation or taking out after storage.
[0029]
In the present invention, in the temporary holding state where the waist flap 1 is folded outward by a certain width, the pick-up portion 51 on the free end side of the disposal fastening tape is positioned below the folded portion of the waist flap 1. And it will be in the state covered with this folded part. For this reason, it is possible to prevent the picking portion 51 from inadvertently touching other objects, thereby preventing the pick-up part from coming off.
[0030]
By the way, as for the underpants type diaper P of the present invention, the waist flap 1 is folded before wearing and until the diaper waist opening D is located at the waist of the wearer at the time of wearing. When the diaper P is provided over the front body A, the crotch B, and the back body C, various folded-back structures are employed.
For example, when the lengths of the absorbent bodies 2 provided in the front body A and the back body C are the same, the folding position of the waist flap 1 is the same for both the front body A and the back body C as shown in FIG. Similarly, it is preferable to match the folding position and match the height of the waist opening D so that the absorber 2 does not reach the folded portion.
[0031]
Moreover, when the length of the absorber 2 with which the front body A and the back body C are equipped differs, as shown in FIG.4 (B), the folding | returning position of the waist flap 1 has both the absorber 2 provided. In order to prevent the absorbent body 2 from reaching the folded part of the body parts A and C, the other body part is aligned with the body part having the absorbent body 2 long, and the height of the waist opening D is matched. preferable.
[0032]
In addition, this folding position is independent of the length of the absorbent body 2 provided in the front body A and the back body C, as shown in FIG. About the part which is not provided, it is also possible to make it the same folding width while making the height of the waist opening D coincide.
As described above, by matching the folding position of the waist flap 1 in the front body A and the back body C of the pants-type diaper P, and matching the height of the waist opening D, it is easy to pack because it is easy to handle during packing, In addition, it looks good.
And when the picking-out part (not shown in FIG. 4) by the side of the free end of the disposal fastening tape 5 is covered with the folded-back portion of the waist flap 1, it is prevented from coming off. .
[0033]
Next, a procedure for wearing the pants-type diaper P will be described.
FIG. 5 is a diagram showing a procedure for attaching the pants-type diaper.
First, before wearing, the waist flap 1 having the high-friction member 11 is folded outward by a predetermined width to be in a temporary holding state (see FIG. 5A) and disposed on the inner surface of the waist flap 1. The high friction member 11 is exposed to the outside.
In this state, put the finger on the waist opening D and the leg opening E and hold it, insert the wearer's leg into the leg opening E of the pant-type diaper P, and then the entire pant-type diaper P Is pulled upward (see FIG. 5B).
[0034]
Then, since the highly frictional member 11 is exposed to the outside in the waist opening D, there is nothing that gives resistance by contacting the skin surface, so the diaper P can be pulled up smoothly. Further, since the waist flap 1 is folded back, the width to be picked by a finger is shortened, and as a result, the waist flap 1 is easily put on. In addition, since the waist flap 1 is folded and doubled at the waist opening D, the waist opening 1 has an appropriate rigidity, so that the upper end line is not easily collapsed, and the whole can be pulled straight up. [Refer FIG.5 (C)].
[0035]
Next, after the waist opening D is positioned on the waist of the wearer, the folded-back waist flap 1 is returned to the original position to release the temporary holding state (see FIG. 5D). Thus, the high friction member 11 is positioned inside the diaper P and comes into contact with the skin surface of the wearer, and is accurately fitted and held by the contraction force of the elastic contraction member S.
In addition, the dirty pants-type diaper P after use is rolled up and reduced in size, and is discarded with the fastening tape 5 for disposal.
[0036]
Although the present invention has been described above, the present invention is not limited to the embodiments, and it goes without saying that other various modifications are possible without departing from the essence thereof.
That is, the arrangement range of the absorbent body 2 can be freely selected over the front body A, the backward C, and the crotch B.
In addition, the structure of the diaper itself can be freely selected.
[0037]
【The invention's effect】
The pants-type diaper P of the present invention is such that the high friction member 11 provided in the waist opening D is not directly in contact with the body, so that when worn, there is little resistance to the body (skin surface), As a result, smooth installation became possible. At the same time, it does not hurt the skin, so it is especially suitable for infants with soft skin.
In addition, when the folded waist flap 1 is temporarily fixed by embossing or heat sealing, a stable maintained state of the folded portion can be ensured.
[0038]
Furthermore, when the pick-up portion 51 on the free end side of the disposal fastening tape 5 is covered with the folded back waist flap 1, the unraveling is prevented.
In addition, since the folded portion is a part of the total length of the diaper that does not have an absorbent body, the area of the diaper inner surface exposed to the outside and exposed to the outside air can be suppressed as much as possible, which is extremely hygienic. .
