DETAILED DESCRIPTION OF THE INVENTION
The male urine absorbing pad according to the present invention will be described below in more detail with respect to an embodiment shown in the drawings. FIG. 1 is a plan view showing a male urine absorbing pad 1 (hereinafter simply referred to as a pad) according to an embodiment of the present invention. The pad 1 is formed by interposing a liquid-absorbent core 5 between a liquid-permeable top sheet 3 and a liquid-impervious back sheet 4 and has a rectangular shape. The top sheet 3 and the back sheet 4 are joined by a known means such as heat fusion, ultrasonic fusion, or adhesive at the peripheral side portion surrounding the core 5 to seal the core 5. Among the four peripheral side portions, opposite elastic upper and lower end portions 2a and 2b are provided with retractable elastic elastic members 6a and 6b between the sheets 3 and 4, respectively.
[0009]
The elastic elastic members 6a and 6b can be thread-like or belt-like, and the upper and lower end portions 2a and 2b to which the elastic elastic members 6a and 6b are attached are gathered by contraction. . The pad 1 has upper and lower end portions 2a, 2b having a length of about 370 mm and both side portions 2c, 2d extending in the longitudinal direction having a length of about 200 mm. In the pad 1 of this size, the elastic elastic members 6a, 6b The length of is about 200 mm.
[0010]
Here, an assembling method when the pad 1 is used will be described. As shown in FIG. 2, the pad 1 has a top sheet 3 on the inside and crossing corners 2e and 2f between the lower end 2b and both sides 2c and 2d at opposite sides 2c as indicated by an arrow line 7a. A cone that folds back in the 2d direction along the imaginary fold line 7b and overlaps the vicinity of the intersection corners 2e and 2f with each other to define a tapered penis accommodating portion from the top to the bottom as shown in FIG. Assembled into a shape.
[0011]
Release paper that protects the surface adhesive layer of the double-sided adhesive tape 9a that is attached to the surface of the back sheet 4 in the vicinity of the intersecting corner 2e when the folded back sides 2c and 2d are overlapped with each other Is removed to fix the overlapping state of both side portions 2c and 2d. Further, the release paper that protects the surface pressure-sensitive adhesive layer of the double-sided adhesive tape 9b attached in the vicinity of the side portion 2d on the front surface of the back sheet 4 is removed to form a conical shape as described above. The assembled pad assembly 10 is fixed to a diaper or underwear.
[0012]
The tapered tip 11 of the pad assembly 10 is formed by rounding the lower end 2b of the pad 1, and conversely, the large-diameter opening 12 is formed by the upper end 2a. The former tapered tip portion 11 is closed by a gather formed at the lower end portion 2b of the pad 1 by a stretchable elastic member 6b, with the left and right side portions 2c and 2d overlapped so as not to form an opening. . This point will be described in detail later. Next, a penis is inserted and used from the large-diameter opening 12 of the conical pad assembly 10 as indicated by an imaginary line in FIG. Further, the pad assembly 10 may be formed (assembled) while the pad 1 is applied to the penis as shown in FIG.
[0013]
In this conical pad assembly 10, when the gather formed on the lower end 2 b by the elastic elastic member 6 b closes the tapered tip 11, the gather at the lower end 2 b completely closes the tip 11. Thus, it is necessary to effectively stand up against the surface of the pad 1 to form a three-dimensional gather. In order to form such a gather at the lower end portion 2b, a recess 8 is formed in a substantially central region in the lateral direction at the lower end edge of the core 5 adjacent to the elastic elastic member 6b. Specifically, the concave portion 8 is formed in a substantially central region in the lateral direction at the lower end edge substantially facing the stretchable elastic member 6b, and the lower end edge of the stretchable elastic member 6b and the core 5 opposed thereto. 8a is separated from the 8a by a predetermined distance.
[0014]
When the depth of the concave portion 8 is defined by the distance from the stretchable elastic member 6b, the distance h between the stretchable elastic member 6b and the lower end edge 8a of the core 5 that is parallel to and defines the concave portion 8 is: It is preferably in the range of about 10 mm to about 40 mm. If the distance h is 10 mm or less, the position of the core 5 and the gathers becomes narrow, the rise of the gathers formed at the lower end 2b is low, and the tapered tip part 11 cannot be sufficiently blocked by the gathers. There is a risk of urine leakage from the tapered tip 11. Moreover, since the lower end edge of the core 5 is close to the elastic elastic member 6b, the rigidity of the core 5 is affected when the elastic elastic member 6b is contracted, so that it is difficult to form a gather at the lower end 2b.
[0015]
On the other hand, if the distance h exceeds 40 mm, the positions of the core 5 and the gathers are widened, so that the gathers formed at the lower end 2b are high, and the tapered tip part 11 can be sufficiently blocked by the gathers. The leak of urine from the tapered tip portion 11 can be prevented, but the gathering is high and the gathering at the center of the lower end portion 2b becomes dense due to the contracted state of the elastic elastic member 6b. Since the gathers on the part side are widened, the gathers rising from the surface of the pad 1 can easily fall into the inside. If it becomes like this, the surface area of the core 5 will reduce, and also an absorption function will be inhibited because a gather covers the core 5.
[0016]
The distance i between the lower end edge of the core 5 and the elastic elastic member 6b on both sides of the recess 8 is about 5 mm. The distance i is the same as the distance between the stretchable elastic members and the core edge of the conventional urine absorbing pad for males, the distance also the dimension of the upper edge of the stretchable elastic members 6a and the core 5 at the upper end 2a It is.
[0017]
For this reason, the distance h between the elastic elastic member 6b and the lower end edge 8a in the recess 8 parallel to the elastic member 6b is set to be in the range of about 10 mm to about 40 mm. It is appropriate in terms of height and holding property in a standing state, and the tapered tip end portion 11 formed by the lower end portion 2b can be effectively blocked by this gather. In this case, the distance h is more preferably 15 mm to 25 mm, and the distance h is further preferably 20 mm .
[0018]
Further, in order to form a gather suitable for closing the tapered tip end portion 11 of the pad assembly 10 at the lower end portion 2b of the pad 1, the rigidity of the core 5 also affects as described above. Therefore, the rigidity of the core 5 is preferably 100 to 250 mN · mm, and if the rigidity is higher than this, not only the lower end 2b can be formed with a gather suitable for closing the tapered tip 11 of the pad assembly 10. If the wearer feels uncomfortable and the rigidity is lower than this, the core 5 is deformed and the operability during assembly (assembleability) is deteriorated.
The rigidity of the core 5 was measured under the following conditions in accordance with JIS P-8125.
(1) Test equipment a. The thickness measuring device (Peacock Dial thickness gauge No.CI1352 diameter 50 mm · Load 3 g / ^cm 2)

b. Place the test piece (sample) between the rollers of the test piece bending device, and attach it so that the test piece grip and the sample are in the same straight line, and the center score is 0 on the load scale (the grip interval is the thickness of the sample) To match).
c. The distance from the roller to the test piece is about 0.5 mm (with or without the sample).
d. Rotate the test piece bending device and stop the rotation of the bending device at the point where the marking indicating 15 degrees of the test piece bending device and the pointer of the load pendulum match. At this time, the load scale indicated by the pendulum pointer read.
e. Immediately rotate in the opposite direction, read the load scale in the same way, and obtain the average value of the load scale in both the left and right directions.
* Auxiliary weight should be selected arbitrarily so that the indicated load scale falls within the range of 15 to 85% of the maximum scale.
(5) Record calculation formula of results Average value of readings on left and right scales x Weight value ÷ 1000 x 9.807
Upper auxiliary weight 1/2, 1 / 2.5, 1/4

Since it can be assembled by simply folding it back into a substantially triangular shape and fastening it with a double-sided adhesive tape 9a, it is very easy to assemble, and the tapered tip 11 has a lower end 2b against the surface of the pad 1. Occurrence of urine leakage can be prevented since it is effectively blocked by gathers that stand up.
