Description

The present invention relates to a pet diaper structure that can be attached to the buttocks of a pet and can be used to reliably store defecation without leaking defecation from the attachment bag.

Conventional pet diapers are unsanitary because the excrement received inside the diaper may adhere to the pet's body. In order to solve the problem, the applicant devised a new diaper for pets, applied for it, and obtained a patent (Patent Document 1).

For this diaper, open an excretion window on the back sheet of the diaper body that wraps the butt, fix the frame on the outer peripheral edge of the excretion window, and communicate the opening edge of the excretion bag with the frame to connect the inside of the excretion bag. In addition to communicating with the excretion window, the upper edge of the valve body that can be opened and closed is connected to the upper edge of the excretion window, and the valve body is made slightly shorter to form an enlarged window located below the excretion window. The structure is such that the defecation body is pushed open and discharged and stored in the excretion bag, and the dripping defecation naturally falls into the excretion bag from the expansion window below and all the stools are sufficiently stored. ..

Japanese Patent No. 6232688

However, the purpose of this improved pet diaper was to ensure that any defecation can be stored in the excretion bag regardless of the condition of the stool. It turned out that it is not always surely stored.

That is, the defecation may not be stored inside the excretion bag from the excretion window of the rear sheet, but may fall directly from the outside of the excretion window through the outside of the excretion bag to the rear sheet of the diaper body to stain the diaper. rice field. The reason seems to be that the direction of defecation shifts from the window for defecation and faces the direction of the diaper body below the window for defecation. This principle is due to the fact that the arrangement direction could not be regulated by the excretion window in the required initial excretion movement regardless of the presence of the valve body.

In this way, if defecation is not stored in the frame of the frame during defecation, defecation will leak from the inside of the diaper body, that is, from the back side of the frame body into the diaper body, which will stain the buttocks of the pet and cause a foul odor. It is not good for hygiene and has a bad influence on the environment.

INDUSTRIAL APPLICABILITY The present invention is an improved structure of a diaper for pets, which is configured to eliminate such leakage of defecation and enable hygienic and comfortable defecation.

In the present invention, an excretion window is opened in the rear sheet of the diaper body that wraps the tail, and the frame is fixed to the outer peripheral edge of the excretion window so that the anus is located near the lower edge of the frame. The frame is connected to the excretion window so that the inside of the frame and the inside of the bag are in an internal communication state with the opening edge of the excretion bag, and the upper edge of the excretion window can be freely bent. A series of auxiliary sheets for opening and expanding the bag, which is wider than the width of the frame, is stretched on the outer surface of the lower half of the valve body so as to protrude from the lower part of the valve body, and between the frame and the tip of the valve body. It provides a diaper structure for pets characterized by forming an enlarged window located at the lower part of the excretion window and forming a notch for tail insertion from the tip of the valve body to the auxiliary sheet for opening and expanding the bag. ..

According to the present invention, a frame is fixed to the outer peripheral edge of the excretion window opened in the rear sheet of the diaper body that wraps the tail, and the upper edge of the excretion window, that is, the upper edge of the frame can be opened and closed. The upper edge of the valve body is foldably connected, and an auxiliary sheet for opening and expanding the bag, which is wider than the width of the frame body, is stretched over the lower half of the valve body so as to protrude from the lower part of the valve body. An enlarged window located at the lower part of the excretion window is formed between the lower edge of the body, and an auxiliary sheet for opening and expanding the bag is extended so as to protrude from the lower part of the valve body to form a square frame and the lower edge of the valve body. A magnifying window located at the lower part of the excretion window is formed between them, and a notch for tail insertion is formed from the lower edge of the valve body to the auxiliary sheet for opening the bag, so that it is particularly located at the lower part of the excretion window. The valve body is formed during defecation due to the formation of an enlarged window and the fact that an auxiliary sheet for expanding the bag, which is wider than the width of the frame body, is stretched over the lower half of the valve body from below the valve body. It is lifted greatly and at the same time the auxiliary sheet for opening and expanding the bag is also lifted, and the inside of the excretion bag is also greatly opened to expand the internal space and the initial defecation operation is surely performed within the regulation range of the excretion window, so defecation is smoothly performed in the bag. It has the effect of preventing the risk of leaking into the diaper on the outside of the excretion bag.

Moreover, since the tail from the notch for tail insertion can be fixed to the upper outer surface of the bag body, the upper outer surface of the bag body is lifted together with the tail to lift the tail as a habit when the pet defecates, and the inside of the bag is lifted. There is an effect that the space inside the bag is expanded and the defecation of the pet is more smoothly and surely stored in the excretion bag through the excretion window.

Specifically, resin can be selected as the material of the plate body 25. If thick paper or the like, which is inferior in waterproofness and durability to resin, is used as the material of the plate body 25, the plate body 25 may be processed to impart waterproofness and durability.

[Valve body]
As shown in FIG. 4, the valve body 17 is a plate-shaped body extending from the lower edge portion of the plate body 25a constituting the upper edge portion of the frame body 14. The valve body 17 is composed of a bent portion 26, a valve body main body 27, and a notch 20a for inserting a tail.

The bent portion 26 is provided at the base end portion (lower edge portion of the plate body 25a) of the valve body 17. The valve body 17 tilts about the bent portion 26 as an axis. As a result, the valve body 27 can freely open and close the opening 30 of the frame body 14.

The valve body 27 is a plate-shaped body having a size and a shape capable of sealing the opening 30 of the frame body 14. Specifically, the edges of the left and right side surfaces of the valve body 27 are formed so as to coincide with the peripheral edge of the opening 30 of the frame body 14. The tip 27a of the lower edge portion of the valve body 27 is formed so as to be at a position H facing the anus 21.

The outer surface of the valve body 27 is fixed to the inner wall of the excretion bag 16 (on the side of the outer surface 29 of the excretion bag) through the excretion bag opening 15 described later. Further, the shape of the valve body 27 can be selected according to the shape of the frame 14 in addition to the square shown in FIG. For example, as shown in FIG. 11, it can be selected from an ellipse, a circle, a trapezoid, a triangle, a heart shape, and the like.

The valve body 27 can also be processed to have a deodorant function and an antibacterial function. Specifically, a sheet having a physical deodorizing function by a sheet containing a porous substance such as activated carbon and a scientific antibacterial function using a chemical reaction such as redox is placed on the inner surface of the valve body 27. Can be attached.

[Excretion bag]
As shown in FIGS. 5 and 6, the excretion bag 16 has an excretion bag inner side surface 28, an excretion bag outer surface 29, an excretion bag opening 15 provided near the upper edge of the excretion bag inner side surface 28, and excretion. It is composed of a notch 20b for inserting a tail provided on the outer surface 29 of the bag. The peripheral edge of the inner side surface 28 of the excretion bag is welded to the peripheral edge of the outer surface 29 of the excretion bag. As a result, the excretion bag 16 forms a bag body having an opening by the excretion bag opening 53 and a notch by the notch 20b for tail insertion.

The inner side surface 28 of the excretion bag and the outer surface 29 of the excretion bag are made of a resin material having excellent waterproofness and durability. Specifically, a polyethylene bag is used.

The excretion bag opening 16 is formed in the same shape as the excretion window 12 provided in the diaper body 10. That is, in the diaper structure for pets according to the present invention, the excretion window 12 provided in the diaper body 10, the opening 30 provided in the frame body 14, and the excretion bag opening 15 provided in the excretion bag 16 communicate with each other in the same shape. It is formed.

The notch 20b for tail insertion is formed so as to communicate with the notch 20a for tail insertion formed at the tip of the valve body 27 fixed to the inner wall of the excretion bag 16.

[Auxiliary sheet for opening and expanding bags]
As shown in FIG. 6, the bag opening / expanding auxiliary sheet 18 is a horizontal rectangular band-shaped body having adhesiveness on one side, and a notch 20c for tail insertion is formed in a substantially central portion. The bag opening / expanding auxiliary sheet 18 is attached to the outer peripheral wall of the excretion bag outer surface 29. When the bag opening / expanding auxiliary sheet 18 is attached to the outer peripheral wall of the excretion bag outer surface 29, the bag opening / expanding auxiliary sheet 18 may be attached so as to be in contact with the substantially lower half of the valve body 17. can.

It is desirable that the material of the bag opening / expanding auxiliary sheet 18 is superior in strength and flexibility to the excretion bag 16 and more flexible than the valve body 17. The width of the bag opening / expanding auxiliary sheet 18 is formed to be wider than that of the frame body 14 and narrower than that of the excretion bag. Further, the vertical width of the bag opening / expanding auxiliary sheet 18 is wide enough to form a notch 20c for tail insertion, which will be described later, and is narrow enough to fit inside the lower edge of the excretion bag.

The bag opening / expanding auxiliary sheet 18 may be replaced with thickening the vicinity of the notch 20b for inserting the tail of the excretion bag 16 or the entire outer surface 29 of the excretion bag of the excretion bag 16. can.

With such a configuration, the bag opening / expanding auxiliary sheet 18 greatly lifts the outer surface 29 of the excretion bag in conjunction with the movement of the tail T. Therefore, the internal space of the excretion bag 16 can be formed as wide as possible. The large internal space of the excretion bag 16 enables more reliable storage of stool.

[Enlarged window]
As shown in FIG. 4, the enlarged window 19 is an opening formed by a peripheral edge portion of the opening 30 included in the frame body 14 and a tip portion 27a of the valve body main body 27.

The size of the magnifying window 19 can be determined as follows. That is, as shown in FIG. 8 or 9, the length from the lower part of the base 23 of the pet's tail to the anus 21 is L1, and the length from the base 23 of the tail to the tip 27a of the valve expansion body 27 is L2. In this case, the magnifying window 19 is formed so that at least L1 <L2.

By forming the magnifying window 19 in this way, the lower edge portion 19a of the magnifying window 19 is located below the anus 21. Depending on the shape of the stool, the stool may be attached to the anus 21. For example, even if liquid stool remains in the vicinity of the anus 21, the stool can flow into the excretion bag 16 through the magnifying window 19.

If the magnifying window 19 is not provided, that is, if the opening 30 of the frame body 14 is completely sealed by the valve body 17, the following problems occur. That is, since the pet P that has finished defecation behavior lowers the tail T downward, the valve body 17 comes into contact with the anus 21. In such a state, the valve body 17 spreads the dirt of the stool in the vicinity of the anus 21 and causes inflammation of the skin of the pet P.

[Cut for tail insertion]
As shown in FIG. 6, the notch 20 for tail insertion includes a notch 20a formed in the valve body 17, a notch 20b formed in the excretion bag 16, and a notch formed in the bag opening auxiliary sheet 18. An opening or a slit formed so as to communicate with 20c. The diameter or width of the notch 20 for inserting the tail is long enough to allow the tail of the pet to be pulled out from the inside to the outside, and is formed shorter than the auxiliary sheet 18 for opening the bag.

The notch 20 for tail insertion makes it possible to pull out the tail T to the outside of the pet diaper structure according to the present invention. As a result, the tail T can be prevented from coming into contact with the defecation 22 housed in the excretion bag 16 and the defecation 22 attached to the anus 21.

The configuration of the diaper main body 10 and the configuration of the defecation device 13 are as described above. In the mounting of the diaper structure for pets in the present invention, the defecation device 13 is attached to the diaper body 10, the pet P is hung from the tail portion to the body portion, and is covered by the connecting means 24 at the front and rear portions of the diaper body 10. It is fixed to the buttock of the pet P, and is completed by pulling out the tail T to the outside through the defecation window 12, the opening of the frame 14, and the notch 20 for inserting the tail.

The structure of the diaper for pets according to the present invention is as described above. Hereinafter, the process in which the defecation 22 is stored in the excretion bag 16 when the pet diaper structure is used will be described.

First, as shown in FIG. 7, the pet P has a diaper structure for pets according to the present invention, which comprises a diaper body 10 having a function of absorbing urine and a defecation device 13 for accommodating stool. Let it be attached. The tail T of the pet P is pulled out from the excretion window 12 through the upper edge of the frame 14 and the lower side of the valve body 17 from the notch 20 (20a, 20b, 20c) for inserting the tail to the outside of the excretion bag 16. It has been. At this time, by forming the width of the notch 20 long enough to allow the pet's tail to penetrate and shorter than the bag opening auxiliary sheet 18, the tail T and the defecation device 13 can be fixed.

As shown in FIG. 7, the anus 21 is located near the lower edge of the base 23 of the tail T. Moreover, the positional relationship between the anus 21 and the excretion window 12 is fixed so as to be constant. This is because the tail T is integrally fixed to the defecation device 13 via the notch 20 (20a, 20b, 20c) for inserting the tail. Further, the defecation device 13 is attached to the peripheral edge of the excretion window 12 of the diaper body 10 via the frame body 14. As a result, even if the tail T moves violently up, down, left and right, the position of the excretion window 12 is restricted by the frame body 14 in the same direction as the tail T, that is, in a position facing the anus 21. As a result, the defecation 22 is stored in the excretion bag 16 through the excretion window 12 regardless of the posture of the pet P.

As shown in FIG. 7, the pet P at the time of defecation has a habit of pushing the tail T upward or horizontally in a tense state. The movement of the tail T causes the valve body 27 to tilt upward with the bent portion 26 as an axis, and lifts the excretion bag 16 from the inside. Further, the bag opening / expanding auxiliary sheet 18 pulls up the excretion bag 16 from the outside and forms the internal space of the excretion bag 16 as large as possible.

Through this step, the defecation 22 is housed in a defecation bag 16 having a large opening, as shown in FIG. Further, when the defecation 22 is flexible and drips downward, the defecation 22 flows into the excretion bag 16 from the enlarged window 19 because the anus 21 is located at a position facing the enlarged window 19. As a result, the defecation 22 can be prevented from leaking to the outside of the defecation device 13, and the defecation bag 16 does not leak into the diaper body 10 on the outside.
