Description

Technical Field

[0001] The present invention relates to a diaper structure for pets that is worn on the pet's buttocks and can reliably store feces without leakage from the wearing bag during use.

Background Art

[0002] In conventional pet diapers, there was a risk that excrement received inside the diaper would adhere to the pet's body, which was unhygienic. To solve such problems, the applicant devised a new pet diaper, applied for a patent, and obtained a patent (Patent Document 1).

[0003] This diaper has an excretion window opened in the rear sheet of the diaper body that wraps around the buttocks, a frame body fixed to the outer peripheral edge of the excretion window, and an excretion bag opening edge communicated with the frame body to communicate the inside of the excretion bag with the excretion window. At the upper edge of the excretion window, an upper edge of a valve body that can be opened and closed is continuously provided, the valve body is made slightly shorter, and an enlarged window located below the lower part of the excretion window is formed below the valve body. Feces are discharged and stored in the excretion bag by pushing open the valve body, and dripping feces naturally fall into the excretion bag from the lower enlarged window, and all feces are configured to be sufficiently stored.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, although such an improved pet diaper aims to be able to reliably store any feces in the excretion bag regardless of the state of the feces, it has been found that in actual use, it is not always reliably stored depending on the pet's physique and the posture and movement during defecation.

[0006] That is, there was a case where feces did not fall into the inside of the excrement bag through the excrement window of the rear sheet but directly dropped from the outside of the excrement window through the outside of the excrement bag onto the rear sheet of the diaper body, soiling the diaper. The reason is thought to be that the direction of defecation deviates from the excrement window and faces the direction of the diaper body below the excrement window. Such a principle is due to the fact that the arrangement direction could not be regulated at the excrement window at the initial stage of excretion regardless of the presence of the valve body.

[0007] In this way, if feces are not stored in the frame of the frame body during defecation, feces will leak from the inside of the diaper body, that is, from the back side of the frame body, into the diaper body, soiling the pet's buttocks, causing a bad smell, being unhygienic, and having an adverse impact on the environment.

[0008] The present invention improves the structure of a diaper for pets configured to eliminate such leakage of feces and enable hygienic and comfortable defecation.

Means for Solving the Problem

[0009] The present invention forms an excrement window 12 in a diaper body 10 that wraps around the buttocks to A frame body 14 is fixed to the outer peripheral edge of the excrement window 12 so that the anus is located near the lower edge inside the frame body. An opening edge of an excrement bag 16 is continuously provided on the frame body 14 so that the inside of the frame body 14 and the inside of the bag communicate with each other. The upper edge of the excrement window is continuously provided with the upper edge of a valve body that can be opened and closed in a bendable manner. On the outer surface of the lower half of the valve body, a bag-expanding auxiliary sheet wider than the lateral width of the frame body protrudes from below the valve body and is stretched. A cut for inserting the tail is formed at approximately the center of the sheet. The outer surface of the excrement bag is lifted greatly in conjunction with the movement of the tail inserted through the cut for inserting the tail, and the internal space of the bag is formed as wide as possible to enable reliable storage of feces. The present invention provides a diaper structure for pets characterized by this configuration.

Effect of the Invention

[0010] According to the present invention, an excrement window 12 is formed in a diaper body 10 that wraps around the buttocks toFormed, the frame body 14 is fixed to the outer peripheral edge of the excretion window 12 such that the anal part is positioned near the lower edge inside the frame body. The opening edge of the excretion bag 16 is continuously provided on the frame body 14 so that the inside of the frame body 14 and the inside of the bag communicate with each other. The upper edge of the excretion window is continuously provided with the upper edge of the valve body that can be opened and closed in a bendable manner. On the outer surface of the lower half of the valve body, a bag expansion auxiliary sheet wider than the lateral width of the frame body protrudes from below the valve body and is stretched. A cut for inserting the tail is formed at approximately the center of the sheet. By configuring the outer side surface of the excretion bag to be greatly lifted in conjunction with the movement of the tail inserted through the cut for inserting the tail, the internal space of the bag is formed as wide as possible to enable reliable storage of feces. Furthermore, an enlarged window located in the excretion window is formed, and in combination with providing a window expansion auxiliary sheet on the valve body, when defecating, the bag expansion auxiliary sheet is lifted, the inside of the excretion bag also opens widely, the internal space expands, and the defecation operation is surely performed within the regulated range of the defecation window, so that feces can be smoothly stored in the bag and the risk of leakage into the diaper outside the excretion bag can be prevented.

[0011] Moreover, since the upper outer surface of the bag body is configured to be able to fix the tail from the cut for inserting the tail, when the pet defecates, as a habit, the tail is lifted, so the upper outer surface of the bag body is lifted together with the tail, the inside of the bag is expanded, the internal space of the bag expands, and the pet's feces can be more smoothly and surely stored from the excretion window into the excretion bag.

Mode for Carrying Out the Invention

[0013] The gist of this invention is that a diaper body 10 that wraps the buttocks is formed with an excretion window 12 to A frame body 14 is fixed to the outer peripheral edge of the excretion window 12 so that the anus is located near the lower edge inside the frame body. An opening edge of an excretion bag 16 is continuously provided on the frame body 14 so that the inside of the frame body 14 and the inside of the bag communicate with each other. An upper edge of a valve body that can be freely opened and closed is continuously provided on the upper edge of the excretion window so as to be freely bendable. A bag expansion auxiliary sheet wider than the lateral width of the frame body is extended from below the valve body and stretched on the outer surface of the lower half of the valve body. A cut for inserting the tail is formed at approximately the center of the sheet. The outer surface of the excretion bag is greatly lifted in conjunction with the movement of the tail inserted through the cut for inserting the tail, and the internal space of the bag is formed as wide as possible to enable reliable storage of feces. Further, an upper edge of the excretion window is continuously provided with a valve body that can be freely opened and closed and whose upper edge can be freely bent, and a bag expansion auxiliary sheet wider than the lateral width of the frame body is stretched on the outer surface of the lower half of the valve body.

[0014] [Pet] The inventor has obtained the following findings from the empirical side. That is, when defecating, pets have the habit of sticking their tails upward or horizontally in a tense state. The diaper structure for pets according to the present invention utilizes this habit. The pet in the present invention is an animal with a tail in a human breeding environment, for example, an animal belonging to the Canidae or Felidae family. In this specification, an embodiment in which the diaper structure for pets according to the present invention is worn by a dog will be described.

[0015] Embodiments of this invention will be described in detail with reference to the drawings. FIG. 1 shows a view of a pet P wearing the diaper for pets according to the present invention. FIGS. 2 to 6 and FIG. 11 show schematic views of the diaper structure for pets according to the present invention. FIGS. 7 to 10 show schematic views for explaining the movement of each component when the pet P wears the diaper structure for pets according to the present invention.

[0016] The diaper structure for pets according to the present invention is composed of a diaper body 10 and a defecation device 13, as shown in FIG. 1. An opening as an excretion window 12 is provided in the diaper body 10 at a position adjacent to the anus of the pet P. The defecation device 13 is attached in a state of internal communication with the excretion window 12. Hereinafter, the structures of the diaper body 10 and the defecation device 13 will be described in detail.

[0017] [Diaper body] As shown in FIG. 2, the diaper body 10 is composed of a rear sheet 11, an excretion window 12, and connecting means 24 (24a·24b). The diaper body 10 is separated at both upper and lower ends, and is generally configured in a substantially gourd shape in plan view.

[0018] The rear sheet 11 is provided at substantially the center of both upper and lower ends of the diaper body 10. The rear sheet 11 can be composed of a material that absorbs urine. A urine reservoir such as a water-absorbing pad may be attached to the contact surface with the local part on the rear sheet 11.

[0019] As shown in Fig. 3, the excretion window 12 is an opening formed at a position adjacent to the anus on the rear sheet 11. The excretion window 12 is formed such that at least the tail T and the anus 21 of the pet P are accommodated inside the opening, and the anus 21 is positioned near the lower edge of the excretion window 12.

[0020] The shape of the excretion window 12 can be freely selected from a square, an ellipse, a circle, a trapezoid, a heart shape, etc. Also, it is desirable that the frame body 14 and the excretion bag opening 15 provided in the defecation device 13 described later have the same shape as the excretion window 12.

[0021] The connecting means 24 is detachably provided at the upper and lower ends of the upper and lower separated diaper main body 10. The connecting means 24 is provided with surface fasteners 24a and 24b such as magic tape (registered trademark).

[0022] The diaper main body 10 is fixedly worn by wearing the rear sheet 11 so as to cover the buttocks of the pet P, and the surface fastener 24a at the upper end and the surface fasteners 24b at the left and right ends of the lower end of the diaper main body 10 are connected on the abdomen and the body of the pet P.

[0023] [Defecation device] The defecation device 13 is attached from the outside at a position facing the excretion window 12 of the diaper main body 10. As shown in Fig. 2, the defecation device 13 includes a frame body 14, a valve body 17 connected to the frame body 14, an excretion bag 16 connected to the opening of the frame body 14, a bag opening expansion auxiliary sheet 18 attached to the excretion bag 16, an expansion window 19 provided between the frame body 14 and the valve body 17, and a cut 20 for inserting the tail. The cut 20 for inserting the tail is composed of a cut 20a formed in the valve body 17, a cut 20b formed in the excretion bag 16, and a cut 20c formed in the bag opening expansion auxiliary sheet 18. Hereinafter, each component will be described in detail.

[0024] [Frame body] As shown in Fig. 4, the frame body 14 is composed of an opening 30 having the same shape as the excretion window 12 and a strip-shaped plate body 25 surrounding the periphery of the opening 30. The frame body 14 is configured in a substantially rectangular frame shape in plan view as a whole by the opening 30 and the plate body 25.

[0025] In addition to the square shape shown in Fig. 4, the frame body 14 can be selected according to the shape of the excretion window 12. For example, as shown in Fig. 11, it can be selected from a circle, an ellipse, a trapezoid, a triangle, a heart shape, etc.

[0026] The defecation device 13 is attached to the diaper body via the plate body 25 of the frame body 14 and is connected integrally. The connecting means between the plate body 25 and the diaper body 10 can be freely selected as long as it has a certain strength, such as an adhesive such as tape or paste, or sewing using natural fibers or chemical fibers.

[0027] The material of the plate body 25 may be selected from materials having waterproofness, durability, and being flexible and excellent in flexibility. Specifically, the material of the plate body 25 can be a resin. If, for example, cardboard or the like, which is inferior to resin in waterproofness and durability, is used as the material of the plate body 25, it can also be used after applying a process for imparting waterproofness and durability to the plate body 25.

[0028] [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 cut 20a for inserting the tail.

[0029] The bent portion 26 is provided at the base end portion of the valve body 17 (the lower edge portion of the plate body 25a). The valve body 17 tilts about the bent portion 26. Thereby, the valve body main body 27 can freely open and close the opening 30 of the frame body 14.

[0030] The valve body main body 27 is a plate-like body with a size and 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 main body 27 are formed to coincide with the peripheral edge of the opening 30 of the frame body 14. The tip 27a of the lower edge of the valve body main body 27 is formed at a position H facing the anus 21.

[0031] The outer surface of the valve body main body 27 is fixed to the inner wall of the excrement bag 16 (on the side of the excrement bag outer surface 29) through the excrement bag opening 15 described later. Also, the shape of the valve body main body 27 can be selected according to the shape of the frame body 14 in addition to the square shape shown in FIG. 4. For example, as shown in FIG. 11, it can be selected from an oval, a circle, a trapezoid, a triangle, a heart shape, etc.

[0032] The valve body main body 27 can also be subjected to processing with a deodorizing function or an antibacterial function. Specifically, a sheet with a physical deodorizing function using a porous material such as activated carbon or a sheet with a scientific antibacterial function using a chemical reaction such as oxidation-reduction can be attached to the inner surface of the valve body main body 27.

[0033] [Excrement bag] As shown in FIGS. 5 and 6, the excrement bag 16 is composed of an inner surface 28 of the excrement bag, an outer surface 29 of the excrement bag, an excrement bag opening 15 provided near the upper edge of the inner surface 28 of the excrement bag, and a cut 20b for inserting the tail provided on the outer surface 29 of the excrement bag. The peripheral edge of the inner surface 28 of the excrement bag is welded to the peripheral edge of the outer surface 29 of the excrement bag. As a result, the excrement bag 16 forms a bag body having an opening by the excrement bag opening 53 and a cut by the cut 20b for inserting the tail.

[0034] The inner surface 28 of the excrement bag and the outer surface 29 of the excrement bag employ a bag made of a resin material excellent in waterproofness and durability. Specifically, a bag made of polyethylene is employed.

[0035] The excrement bag opening 16 is formed in the same shape as the excrement window 12 provided in the diaper body 10. That is, in the pet diaper structure according to the present invention, the excrement window 12 provided in the diaper body 10, the opening 30 provided in the frame body 14, and the excrement bag opening 15 provided in the excrement bag 16 are formed to communicate with each other in the same shape.

[0036] The cut 20b for inserting the tail is formed in a communicating state with the cut 20a for inserting the tail formed at the tip of the valve body main body 27 fixed to the inner wall of the excrement bag 16.

[0037] [Auxiliary sheet for expanding the bag] As shown in FIG. 6, the auxiliary sheet 18 for expanding the bag is a horizontally long rectangular belt-like body having adhesiveness on one side, and a cut 20c for inserting the tail is formed at a substantially central portion. The auxiliary sheet 18 for expanding the bag is attached to the outer peripheral wall of the outer side surface 29 of the excrement bag. When attaching the auxiliary sheet 18 for expanding the bag to the outer peripheral wall of the outer side surface 29 of the excrement bag, the auxiliary sheet 18 for expanding the bag can be attached so as to contact substantially the lower half of the valve body 17.

[0038] The material of the auxiliary sheet 18 for expanding the bag is preferably one that is superior in strength and flexibility to the excrement bag 16 and is softer than the valve body 17. The lateral width of the auxiliary sheet 18 for expanding the bag is formed wider than the frame body 14 and narrower than the excrement bag. Further, the longitudinal width of the auxiliary sheet 18 for expanding the bag is formed wide enough to form the cut 20c for inserting the tail described later and narrow enough to fit inside the lower edge of the excrement bag.

[0039] Note that the above-described auxiliary sheet 18 for expanding the bag can also be replaced by forming the vicinity of the cut 20b for inserting the tail provided in the excrement bag 16 or the entire outer side surface 29 of the excrement bag 16 to be thick.

[0040] With such a configuration, the auxiliary sheet 18 for expanding the bag greatly lifts the outer side surface 29 of the excrement bag in conjunction with the movement of the tail T. Therefore, the internal space of the excrement bag 16 can be formed as wide as possible. The wide internal space of the excrement bag 16 enables more reliable storage of feces.

[0041] [Enlarged window] The enlarged window 19 is an opening formed by the peripheral edge of the opening 30 provided in the frame body 14 and the tip portion 27a of the valve body main body 27, as shown in FIG. 4.

[0042] The size of the enlarged window 19 can be determined as follows. That is, as shown in FIG. 8 or FIG. 9, when 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 portion 27a of the enlarged valve body main body 27 is L2, the enlarged window 19 is formed such that at least L1 < L2.

[0043] By forming the enlarged window 19 in this way, the lower edge portion 19a of the enlarged window 19 will be located below the anus 21. Depending on the shape of the feces, there is also a possibility that feces adheres to the anus 21. For example, even when liquid feces remains near the anus 21, the feces can flow into the excrement bag 16 through the enlarged window 19.

[0044] If the enlarged 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 will occur. That is, since the pet P that has finished defecating lowers its tail T downward, the valve body 17 will come into contact with the anus 21. In such a state, the valve body 17 will spread fecal stains near the anus 21, which may cause inflammation on the skin of the pet P.

[0045] [Cut for tail insertion] The cut 20 for tail insertion is an opening or slit formed such that the cut 20a formed in the valve body 17, the cut 20b formed in the excrement bag 16, and the cut 20c formed in the auxiliary sheet 18 for expanding the bag communicate with each other, as shown in FIG. 6. The diameter or width of the cut 20 for tail insertion is formed long enough for the pet's tail to be pulled out from the inside to the outside, and shorter than the auxiliary sheet 18 for opening the bag.

[0046] The cut 20 for inserting the tail enables the tail T of the pet to be drawn out of the outside of the diaper structure for pets according to the present invention. Thereby, the tail T can be prevented from coming into contact with the excrement 22 stored in the excrement bag 16 or the excrement 22 adhering to the anus 21.

[0047] The configuration of the diaper main body 10 and the configuration of the excrement discharging device 13 are as described above. The wearing of the diaper structure for pets in this invention is completed by covering from the buttocks to the body of the pet P with the excrement discharging device 13 attached to the diaper main body 10, fixing it to the buttocks of the pet P by the connecting means 24 at the front and rear parts of the diaper main body 10, and pulling out the tail T to the outside through the excrement discharging window 12, the opening of the frame body 14, and the cut 20 for inserting the tail.

[0048] The diaper structure for pets according to the present invention has the configuration as described above. Hereinafter, the process in which the excrement 22 is stored in the excrement bag 16 when this diaper structure for pets is used will be described.

[0049] First, as shown in FIG. 7, the pet P is made to wear the diaper structure for pets according to the present invention, which is composed of a diaper main body 10 having a function of absorbing urine and an excrement discharging device 13 for storing feces. The tail T of the pet P is drawn out of the outside of the excrement bag 16 from the excrement discharging window 12, through the upper edge of the frame body 14 and the lower side of the valve body 17, and through the cuts 20 (20a, 20b, 20c) for inserting the tail. At this time, by forming the width of the cut 20 to be long enough for the tail of the pet to pass through and shorter than the auxiliary sheet 18 for opening the bag, the tail T and the excrement discharging device 13 can be fixed.

[0050] 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 fixed integrally with the defecation device 13 through the incisions 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 a frame body 14. Thereby, even if the tail T moves violently up, down, left, or right, the position of the excretion window 12 is restricted by the frame body 14 to the same direction as the tail T, that is, the position facing the anus 21. As a result, no matter what posture the pet P is in, the feces 22 will be stored in the excretion bag 16 through the excretion window 12.

[0051] When defecating, as shown in Fig. 7, the pet P has a habit of thrusting the tail T upward or horizontally in a tense state. Due to this movement of the tail T, the valve body main body 27 tilts upward about the bending portion 26 as an axis, lifting the excretion bag 16 from the inside. Also, the auxiliary sheet 18 for expanding the bag pulls up the excretion bag 16 from the outside, forming the internal space of the excretion bag 16 as large as possible.

[0052] Through such a process, the feces 22 are stored in the largely opened excretion bag 16 as shown in Fig. 10. Also, when the feces 22 are in a soft state and dripping downward, since the anus 21 is at a position facing the expansion window 19, the feces 22 flow into the excretion bag 16 from the expansion window 19. Thereby, it is possible to prevent the feces 22 from leaking outside the defecation device 13 and from being left inside the diaper body 10 outside the excretion bag 16.
