In Patent Document 2, although the absorption capacity is effectively used, the urine component is diffused with high efficiency to prevent leakage, and the liquid return to the wearer's skin is suppressed, it is improved in terms of preventing leakage of excrement. There is room for.

Further, in Patent Document 3, the male genitals are prevented from protruding and lateral leakage, and in Patent Document 4, the diaper can be worn while standing upright for the elderly and the like, and the diaper can be easily worn. Patent Document 5 makes it possible to limit the amount of absorbed urine remaining in the diaper to a certain level by replacing the urine leak pad, and Patent Document 6 enhances the urine absorption performance by using an absorption basic material and a super-absorbable polymer powder. Patent Document 7 presents a bag-like structure in which both side edges of the end edge of the diaper body are joined, and Patent Document 8 presents a fixing cylinder that can be attached and fixed to the penis in a bag-shaped cap that can be turned inside out. Is provided. However, all of Patent Documents 1 to 8 lack a structure for actively collecting excrement to rationally prevent leakage such as lateral leakage, and there is room for strengthening measures against leakage of excrement with a simple structure. It was left.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to rationally receive and accommodate defecation, to enable rapid absorption of urination without leakage, and thus to greatly improve the absorption efficiency of urination. The purpose is to provide practically excellent disposable diapers that contribute to the prevention of side leakage from the crotch, and at the same time, have an inexpensive and simple structure and are easy to use.

In order to solve the above problems, the disposable diaper of the present invention includes a diaper body having an outer absorbent sheet including a core material of an absorber, which constitutes a front pad portion, a crotch pad portion and a rear pad portion, and a crotch. The inside including the core material of the absorber, which is provided so as to overlap the pad and has an opening formed at a position corresponding to the crotch pad so that the wearer's urinary organ is placed inside the opening when using the diaper. an absorbent sheet, a flexible provided in communication with the opening peripheral edge of the opening; and a spacer having an annular ring, for urination the resulting gap between the inner absorbent sheet and the outer absorbent sheet It is characterized by being a discharge space.

In the above-described configuration of the present invention, the tip of the protrusion is brought into contact with the outer absorbing sheet to provide a discharge space between the inner absorbing sheet and the outer absorbing sheet . That is, a bag-shaped structure is formed by the inner absorbing sheet and the outer absorbing sheet, and even when a large amount of urination occurs at one time, the urination is effectively trapped in the bag-shaped structure and does not leak to the outside. Moreover, both inner surfaces of the inner absorption sheet and the outer absorption sheet have a large area, the absorption area for urination becomes large, and the absorption can be performed quickly with high absorption efficiency. In addition, since a flexible spacer (annular ring) is provided detachably, even if the diaper body wearer takes various positions, the diaper body can be held in a shape according to the wearer's position change.

Further, the annular ring may be formed of elastic rubber.

The opening of the inner absorbent sheet can be shaped to accommodate the male urinary system. As a result, the opening is shaped according to the penis and scrotum of the male urinary system, which makes it easier for the wearer to place the male urinary system in the opening and allows the wearer to urinate with peace of mind.

In addition, the annular ring of the spacer is arranged in a state of descending or ascending to the front contact portion with respect to the portion of the diaper body facing the inner absorbing sheet , and the inner absorbing sheet is raised in a semi-cylindrical shape and is worn by the wearer. It can be configured to form a reservoir that houses the penis and scrotum. According to the above configuration, the annular ring is arranged in an inclined state with respect to the part of the diaper body facing the inner absorbent sheet (crotch pad), and the inner absorbent sheet is raised in a semi-cylindrical shape to raise the penis and scrotum of the wearer. A storage unit for accommodating the unit is formed. For this reason, as the wearer wears the penis and scrotum, the penis and scrotum completely fit into the storage portion, so that the storage portion becomes a nepenthes-shaped urinal, and urination can be performed with peace of mind.

Annular ring between the circumferential direction along which intermittently erected a plurality of protrusions at predetermined intervals, the tip portion is brought into contact with the outer absorbent sheet inner absorbent sheet and the outer absorbent sheet projections The gap created in the above can be used as the discharge space. As a result, defecation and urination diffuse from the drainage space of the opening to the front and back and left and right even if the wearer of the diaper body lies on his or her back or lies down, and is quickly distributed over the entire surface of the diaper body. Is effectively absorbed. As a result, the absorption efficiency of urination can be significantly improved, which can contribute to the prevention of side leakage from the crotch.

The protrusion can be formed as an integral body with respect to the annular ring, for example. As a result, the spacer can be easily handled and can contribute to prevention of loss.

The annular ring of the spacer can be fixedly attached to the peripheral edge of the opening. According to this configuration, the spacer is attached in a fixed state, which provides the convenience of being able to directly wear a disposable diaper. On the other hand, the annular ring of the spacer can be detachably attached to the peripheral edge of the opening. As a result, when a plurality of disposable diapers are used one by one in order, a single spacer can be used in common, and versatility can be obtained.

The opening of the inner absorbent sheet can then be formed so that the wearer's buttocks and urinary system are located inside the opening when using the diaper. As a result, the disposable diaper can be applied to both urination and defecation of the wearer.

The opening of the inner absorbent sheet may be formed, for example, to form only one opening in which the wearer's buttocks and urinary organs can be arranged together. On the other hand, the opening can also be formed to consist of a first opening corresponding to the wearer's urinary system and a second opening corresponding to the buttocks. With the first opening and the second opening of the configuration, defecation and urination can be discharged from different places to the empty drain. The inner absorbing sheet can form the second opening larger than the first opening. Further, in the inner absorbing sheet , the first opening and the second opening can be integrated with each other in a gourd shape, for example.

On the other hand, the first opening and the second opening may be communicated with each other through a narrow passage, or the first opening and the second opening may be formed separately from each other. According to this configuration, there is an advantage that the positions of urination and defecation can be easily identified and confirmed.

Further, both the first opening and the second opening of the inner absorbing sheet can be formed in a heart shape. Although urination and defecation are performed in a tail cage, according to the above configuration, the tail cage property can be alleviated by the lightness of the shapes of the first opening and the second opening.

Further, the diaper body may be configured as a pants-type diaper. Wearing the diaper body at the time of use has the advantage of being easy to wear.
