Description

[Technical Field]

[0001] The present invention relates to a pet diaper structure that can be easily attached to the buttocks of a pet, can reliably contain excrement without leakage from the attachment bag, and is highly durable. [Background technology]

[0002] Conventional pet diapers are unhygienic because waste collected inside the diaper can stick to the pet's body. To solve this problem, the applicant devised a new pet diaper, applied for a patent, and obtained a patent (Patent Document 1).

[0003] This improved pet diaper has an excretion window opened in the rear sheet of the diaper body that covers the buttocks, a frame body fixed to the outer peripheral edge of the excretion window, the opening edge of the excretion bag connected to the frame body to connect the inside of the excretion bag to the excretion window, the upper edge of the excretion window is connected to the upper edge of the excretion window, the valve body is slightly short and an enlarged window is formed below the valve body and located below the excretion window, the excretion is pushed open and discharged into the excretion bag, and dripping excretion falls naturally into the excretion bag from the expanded window at the bottom, so that all excretion can be adequately stored.

[0004] In addition, this improved pet diaper is configured such that a bag-opening auxiliary sheet that is wider than the width of the frame body is stretched over the lower half of the valve body, extending from below the valve body, an enlarged window is formed between the frame body and the lower edge of the valve body and located below the excretion window, and a notch for inserting a tail is formed from the tip of the valve body to the bag-opening auxiliary sheet.

[0005] [Patent Document 1] Patent No. 6232688 Summary of the Invention [Problem to be solved by the invention]

[0006] However, because the slit for inserting the tail in such improved pet diapers is formed at the boundary between the bag and the valve body, there are cases where the pet's tail cannot be fully pulled out depending on its size, which causes stress for the pet, and if the slit is large, there is a risk that the bag will come off the tail and slide off, which could result in the excrement bag not being able to store enough feces.

[0007] A pet's habit of defecating is to always raise its tail, and with conventional defecation devices, the action of raising the tail lifts the excretion bag from the inside, expanding the inside of the bag. Because the bag is inevitably expanded from inside the bag via the tail, a load is placed on the tail, causing stress for the pet. In addition, the tail must be pulled out from inside the excretion bag through the slit, which can be stressful in itself, and the complicated process causes stress in a different way for the owner.

[0008] The present invention provides a pet diaper structure that basically exposes the pet's tail outside the excretion bag and engages with the outer surface of the bag, so that the tail's standing movement expands the excretion bag from outside the bag, thereby minimizing stress on the pet when wearing the excretion bag as much as possible, making it easy to put on and take off the pet, and since no tail insertion hole is required in the excretion bag, there is no risk of the bag being damaged through this hole. [Means for solving the problem]

[0009] The present invention provides a pet diaper structure characterized by having an excretion window and a hole for inserting the tail in the rear sheet of the diaper body that covers the buttocks, a frame body fixed to the outer peripheral edge of the excretion window so that the anus is located near the lower edge of the frame body, the excretion bag opening edge is fixed to the frame body in an internally connected state and the excretion bag is connected to the frame body, the upper edge of a valve body that can be opened and closed freely is connected to the upper edge of the frame body opening so that it can be bent freely, and connecting means is provided on the outer peripheral surface of the excretion bag that abuts against the valve body, for connecting the pet's tail, excretion bag, and valve body together after it has been pulled out through the hole for inserting the tail.

[0010] The present invention also provides a pet diaper structure characterized in that an excretion window and a hole for inserting the tail are formed in the rear sheet of the diaper body that covers the buttocks, a frame body is fixed to the outer peripheral edge of the excretion window so that the anus is located within the frame body, the excretion bag opening edge is fixed to the frame body in an internally communicating state and the excretion bag is connected to the frame body, the lower edge of a bendable valve body is connected to the outer upper edge of the frame body so that it can be bent freely, the valve body is in close contact with the outer surface that faces the inner surface of the excretion bag to which the frame body is fixed, and the vertical width of the inner surface of the excretion bag is longer than the vertical width of the outer surface of the excretion bag, and the valve body lifts the outer surface of the excretion bag upward, thereby maintaining a constant space between the frame body and the outer surface of the excretion bag. [Effects of the Invention]

[0011] According to the present invention, by providing a fastening means for fastening a pet's tail on the outer surface of the excretion bag to which the valve body is fixed, owners can easily put on and take off diapers for their pets. In particular, since the tail can be easily attached and removed from the outside of the bag, the process of putting on and taking off the diaper is easy, and the pet can defecate comfortably without causing unnecessary stress. Furthermore, the valve body, together with the relaxed state of the tail after excretion, closes the excretion window of the frame, thereby preventing the leakage of foul odors from the excretion bag from the inside of the diaper body to the outside. Furthermore, if the valve body is configured to have a deodorizing function, it can block out foul odors from the excretion bag as much as possible, further improving the surrounding hygienic environment. Furthermore, since the excretion bag does not have a slit for inserting the tail, as in conventional pet diapers, it has the effect of preventing accidents involving the excretion bag being broken.

[0012] In addition, an excretion window and a hole for inserting the tail are formed in the rear sheet of the diaper body that covers the buttocks, a frame body is fixed to the outer peripheral edge of the excretion window so that the anus is located within the frame body, the excretion bag opening edge is fixed to the frame body in an internally communicating state and the excretion bag is connected to the frame body, the lower edge of a bendable valve body is connected to the outer upper edge of the frame body so that it can be bent freely, the valve body is in close contact with the outer surface that faces the inner surface of the excretion bag to which the frame body is fixed, and the vertical width of the inner surface of the excretion bag is longer than the vertical width of the outer surface of the excretion bag, and the valve body lifts the outer surface of the excretion bag upward, so that a fixed space can be maintained between the frame body and the outer surface of the excretion bag, thereby achieving the following effects.

[0013] That is, the lower edge of the bendable valve body is connected to the outer upper edge of the frame so that it can be bent freely, and the valve body is in close contact with the outer surface of the excretion bag that faces the inner surface to which the frame body is fixed, so that it has the effect of expanding the internal space of the excretion bag regardless of the pet's tail standing up. As a result, there is no need to engage the pet's tail with the valve body, which reduces stress on the pet when wearing the pet diaper structure as much as possible, makes it easy to put on and take off the pet, and since there is no need for a tail insertion hole in the excretion bag, there is the effect of preventing the bag from being damaged through this hole.

[0014] The valve body is in intimate contact with the outer surface of the excretion bag connected to the frame, which faces the inner surface of the excretion bag. The vertical width of the inner surface of the excretion bag is greater than the vertical width of the outer surface of the excretion bag, allowing the excretion bag to be held in a semicircular arc shape in a side view. This creates a sufficient space between the frame and the outer surface of the excretion bag to allow excreta introduced through the frame to smoothly fall to the bottom of the excretion bag. As a result, the inside of the outer surface of the excretion bag facing the frame is not soiled, preventing excreta from soiling the area around the pet's anus, and contributing to a hygienic environment when the diaper is worn.

[0016] The essential features of this invention are that an excretion window and a hole for inserting the tail are formed in the rear sheet of the diaper body that covers the buttocks, a frame body is fixed to the outer peripheral edge of the excretion window so that the anus is positioned near the lower edge of the frame body, the excretion bag opening edge is fixed to the frame body in an internally connected state and the excretion bag is connected to the frame body, the upper edge of a valve body that can be opened and closed freely is connected to the upper edge of the frame body opening so that it can be bent freely, and connecting means is provided on the outer peripheral surface of the excretion bag that abuts against the valve body to connect the pet's tail, excretion bag, and valve body together after they have been pulled out through the hole for inserting the tail.

[0017] [Pets] The inventors have empirically learned the following: pets have a habit of tensing their tails and thrusting them upward or horizontally when defecating. The pet diaper structure of the present invention utilizes this habit. In the present invention, a pet is an animal with a tail that is kept in a human environment, such as an animal belonging to the canine or feline family. This specification describes an example in which the pet diaper structure of the present invention is worn by a dog.

[0018] An embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 shows a pet P wearing a pet diaper 1 according to the present invention. Figs. 2 to 6 show schematic diagrams of the pet diaper structure 1 according to the present invention. Figs. 7 and 8 show schematic diagrams illustrating the movement of each component when the pet P wears the pet diaper structure 1 according to the present invention.

[0019] As shown in FIG. 1, the pet diaper structure 1 according to the present invention is composed of a diaper body 10 and a defecation device 20. The diaper body 10 has openings through which the rear legs of the pet P can pass. The pet P puts on the diaper body 10 by passing its legs through these openings. The diaper body 10 has an opening (excretion window 14) at a position opposite the anus 11 of the pet P. and others The defecation device 20 is attached to the opening in a state of internal communication with the opening. The structures of the diaper body 10 and the defecation device 20 will be described in detail below.

[0020] [Diaper body] The diaper body 10 is worn around the lower abdomen to capture excrement such as urine and feces. As shown in Figure 2, the diaper body 10 comprises a rear sheet 12, a tail hole 13, an excretion window 14, a back split 15, a diaper connection means 16, and leg insertion holes 17L and 17R.

[0021] As shown in Fig. 3, the rear sheet 12 is provided in a position adjacent to the area around the anus 11 of the pet P. The rear sheet 12 can be made of a material that absorbs urine. A urine reservoir such as a water-absorbing pad may be attached to the inner surface of the rear sheet 12.

[0022] The tail insertion hole 13 is a substantially circular opening formed in the rear sheet 12. When wearing the diaper body 10, the pet P can pull out its tail T to the outside of the diaper body 10 through the tail insertion hole 13. This prevents the inside of the diaper from getting too stuffy and prevents the tail T from getting soiled by feces and urine. In addition, the diaper body 10 is designed to be in close contact with the anus 11 and private parts, preventing feces 18 and urine from leaking out of the diaper body 10.

[0023] The excretion window 14 is a substantially oval opening formed at the lower edge of the tail insertion hole 13. The excretion window 14 may be formed integrally with the tail insertion hole 13 or may be formed separately. The size of the excretion window 14 is determined so that the anus 11 fits within the opening when the diaper body 10 is worn. The shape of the excretion window 14 may be freely selected, such as square, oval, circular, trapezoidal, heart-shaped, etc.

[0024] The shape of the excretion window 14 is related to the shape of the frame body 30 that is connected to it in an internally communicating state, and an important object of the present invention is to configure the excretion window 14 so that it does not allow feces 18 to leak through it and into the diaper body 10.To achieve this, it is important that the shapes of the excretion window 14 and the frame body 30 are configured to extend as far downward as possible, and it is important that they are configured so that even if the position of the anus 11 is lowered due to the physique of the pet P, the feces 18 can be scooped up within the excretion window 14 and the frame body 30 as much as possible.

[0025] The back split portion 15 is a cut provided on the back side of the diaper body 10. 10 It is formed perpendicularly from the peripheral edge of the back side of the body towards the window 13 for inserting the tail.

[0026] The diaper connecting means 16 can be freely selected as long as it connects both the left and right sides of the back split 15, as shown in Figure 1. Specifically, it can be selected from hook-and-loop fasteners 16a, buttons, strings, tape, etc.

[0027] The provision of the back split portion 15 and the diaper fastening means 16 in the diaper body 10 makes it easier to put the diaper body 10 on the pet P. As a result, the hassle of putting the diaper on the pet P is minimized. Furthermore, a diaper body 10 of a given size can be used for a wide range of dog breeds. In other words, even if the diaper body 10 is available in a limited number of sizes, it can accommodate pets P of various builds.

[0028] [Defecation device] A defecation device 20, which will be described later, is attached from the outside of the diaper body 10 at a position adjacent to the excretion window 14. As shown in Figure 3, the defecation device 20 basically comprises a frame body 30, a valve body 40 connected to the frame body 30, an excretion bag 50 connected to the opening of the frame body 30, and a tail connecting means 60 fixed from the valve body 40 to the excretion bag 50. Each component will be described in detail below.

[0029] [Frame] As shown in Figure 3, the frame body 30 is made up of an opening 31 of the same shape as the excretion window 14, a strip-shaped plate body 32 surrounding the periphery of the opening 31, and a tail abutment part 33. The tail abutment part 33 is formed by cutting out the plate body 32 that forms the upper side of the frame body 30. The frame body 30 is configured as a roughly U-shaped frame in a plan view overall, with the opening 31, plate body 32, and tail abutment part 33.

[0030] The shape of the frame 30 may be changed depending on the shape of the excretion window 14. For example, as shown in Fig. 4, it may be selected from oval, circular, trapezoidal, triangular, heart-shaped, etc.

[0031] The defecation device 20 is attached to the diaper body 10 via the plate 32 of the frame 30. The means for attaching the plate 32 to the diaper body 10 can be freely selected as long as it has a certain strength, such as adhesive such as tape or glue, or sewing using natural or chemical fibers.

[0032] The material of the plate 32 may be selected from materials that are waterproof, durable, soft, and flexible. Specifically, resin can be selected as the material of the plate 32. If cardboard or the like, which is inferior to resin in terms of waterproofness and durability, is used as the material of the plate 32, the plate 32 can be processed to impart waterproofness and durability.

[0033] In addition, the frame 30 can be freely selected as long as it maintains the shape of the excretion window 14 and functions to further increase the strength of the periphery of the excretion window 14. In other words, adhesives such as adhesive tape or glue placed on the periphery of the excretion window 14 are naturally included in the concept of the frame 30 as long as they perform the same function.

[0034] [Valve body] 3 and 4, the valve body 40 is a plate-like body extending from the lower edge of the plate body 32 that constitutes the upper edge of the frame body 30. The valve body 40 is composed of a bent portion 41 and a valve body main body 42.

[0035] The bent portion 41 is provided at the base end of the valve body 40. The valve body 40 tilts about the bent portion 41 as an axis. This allows the valve body main body 42 to freely open and close the opening 31 of the frame body 30.

[0036] The valve body 42 is a plate-like body having a size and shape that allows it to seal the opening 31 of the frame 30. Specifically, the peripheral edge of the valve body 42 is formed to match the peripheral edge of the opening 31 of the frame 30.

[0037] The outer surface of the valve body 42 is fixed to the inner wall of the excretion bag 50 (the excretion bag outer surface 52 side) via an excretion bag opening 53, which will be described later. The shape of the valve body 42 can be changed as appropriate depending on the shape of the frame 30, as shown in FIG.

[0038] The valve body 40 can also be treated to have deodorizing and antibacterial properties. Specifically, a physical deodorizing function using a porous substance such as activated carbon, or a chemical reaction such as oxidation-reduction, can be used. transformation A sheet having chemical and antibacterial properties can be attached to the inner surface of the valve body main body 42.

[0039] [Excretion bag] 5 and 6, the excretion bag 50 is composed of an inner surface 51 of the excretion bag, an outer surface 52 of the excretion bag, and an excretion bag opening 53 provided near the upper edge of the inner surface 51 of the excretion bag. The peripheral edge of the inner surface 51 of the excretion bag is welded to the peripheral edge of the outer surface 52 of the excretion bag. As a result, the excretion bag 50 forms a bag body with one opening formed by the excretion bag opening 53.

[0040] The excretion bag inner surface 51 and the excretion bag outer surface 52 are made of a waterproof and durable resin material. Specifically, polyethylene bags are used.

[0041] The excretion bag opening 53 is formed in the same shape as the excretion window 14 provided in the diaper body 10. That is, in the pet diaper structure 1 according to the present invention, the excretion window 14 provided in the diaper body 10, the opening 31 provided in the frame body 30, and the excretion bag opening 53 provided in the excretion bag 50 are formed to be in communication with each other and have the same shape.

[0042] [Tail connection method] As shown in Figure 3, the tail connecting means 60 is composed of an adhesive part 61 that is attached to the outer surface 52 of the excretion bag, a band-shaped part 62 that branches into two with the adhesive part 61 as its base end, and connecting parts 63 attached to both the left and right ends of the band-shaped part 62.

[0043] 6, the adhesive part 61 is provided at a position facing the valve body main body 42 and the outer surface 52 of the excretion bag. The attachment method can be freely selected from adhesive, sewing, pressure bonding, etc.

[0044] The belt-shaped portion 62 is formed from a cloth, resin, rubber string, or a combination thereof, and is long from side to side. The width of the belt-shaped portion 62 is formed to a length that can sufficiently wrap around the tail T of the pet P. The vertical width of the belt-shaped portion 62 is formed to a length that fits within the vertical width of the valve body main body 42.

[0045] The connecting part 63 can be freely selected as long as it connects the two forked band-like parts 62. Specifically, a hook-and-loop fastener or a button can be selected. Instead of the connecting part 63, the band-like part 62 may be tied to the tail T to form an integrated part.

[0046] The connecting part 63 may be attached to the entire surface of the belt-shaped part 62, or may be shaped so that it can be fixed at any position on the belt-shaped part 62. This allows for a secure connection between the tail T and the defecation device 20, regardless of the length or amount of hair on the tail T.

[0047] Furthermore, by providing the tail connecting means 60, the tail T is positioned outside the defecation device 20. This prevents the tail T from coming into contact with the anus 11 to which the feces 18 are attached. As the feces 18 are not attached to the tail T, it is possible to prevent the tail T from getting a rash.

[0048] The configuration of the diaper body 10 and the configuration of the defecation device 20 are as described above. The pet diaper structure 1 according to the present invention is put on in the following manner. The legs of the pet P are pulled out through the leg insertion holes 17L and 17R provided in the diaper body 10. Then, the tail T is pulled out through the tail insertion hole 13 and connected to the defecation device 20 via the tail connecting means 60. Finally, the back opening 15 of the diaper body 10 is closed by the diaper connecting means 16.

[0049] Hereinafter, the process by which excrement 18 is stored in the excrement bag 50 provided in the excretion device 20 when the pet diaper structure 1 is used on the pet P will be described.

[0050] As shown in Figure 7, a pet diaper structure 1 comprising a diaper body 10 and a defecation device 20 was fitted to a pet P. Fitting is completed when the tail T is pulled out of the tail insertion hole 13 in the diaper body 10 and secured by the tail connecting means 60 of the defecation device 20. The diaper body 10 has the function of absorbing urine. The defecation device 20 has the function of containing feces.

[0051] As shown in Figure 8, when the pet P defecates, it thrusts its tail T upward or horizontally in a tense state. The tail T is connected to the outer surface 52 of the excretion bag 50 and the valve body main body 42 of the valve body 40 by a tail connecting means 60. With this configuration, the excretion bag 50 is lifted from the outside in conjunction with the pet P's movement of thrusting its tail T upward. As a result, the space inside the excretion bag 50 is expanded as much as possible, and the excretion 18 is contained within the wide-opening excretion bag 50.

[0052] As shown in Figure 9, a bag-opening auxiliary sheet 54 can be attached near the adhesive part 61 on the outer surface 52 of the excretion bag. The bag-opening auxiliary sheet 54 is made of a material with a certain degree of strength and flexibility, and is a horizontally long strip with adhesive on one side.

[0053] The bag-opening auxiliary sheet 54 may be formed by thickening a portion of the outer surface 52 of the excretion bag or the entire outer surface 52 of the excretion bag.

[0054] The bag-opening auxiliary sheet 54 significantly lifts the outer surface 52 of the excretion bag in conjunction with the movement of the tail T. This allows the internal space of the excretion bag 50 to be as large as possible. The large internal space of the excretion bag 50 allows for more reliable storage of feces.

[0055] The valve body 42 is fixed integrally to the inner wall of the excretion bag outer surface 52. That is, when the excretion bag 50 expands, the valve body 42 also displaces upward, allowing for smooth defecation without interfering with the excretion 18, and when the pet P finishes defecation and its tail T, which has been standing up as a habit, returns to its original hanging position, the valve body 42 also closes in the direction of the excretion window 14 and the frame body 30, blocking the spaces of the excretion window 14 and the frame body 30 and preventing the foul odor of excretion from leaking into the inside of the diaper body 10.

[0056] In another embodiment of the present invention, the pet diaper structure 2 has an excretion window 14 and a tail insertion hole 13 formed in the rear sheet 12 of the diaper body 10 that wraps around the buttocks, a frame body 30 fixed to the outer periphery of the excretion window 14 so that the anus 11 is positioned within the frame body, an excretion bag opening 53 edge portion is fixed to the frame body 30 in an internally communicating state, and an excretion bag 50 is connected to the frame body 30, and a bendable valve body 201 lower edge is folded at the outer upper end edge 30a of the frame body. The valve body 201 is connected so as to be flexible, and is in intimate contact with the outer surface 52 of the excretion bag 50, which faces the inner surface 51 of the excretion bag 50 to which the frame body 30 is fixed. The widths of the inner surface 51 of the excretion bag from top to bottom are longer than the widths of the outer surface 52 of the excretion bag from top to bottom, and the valve body 201 lifts the outer surface 52 of the excretion bag upward, thereby maintaining a fixed space between the frame body 30 and the outer surface 52 of the excretion bag 50.

[0057] Specifically, the defecation device 200 provided in the pet diaper structure 2 in this embodiment is configured such that the lower edge of the valve body 201 is connected to approximately the center of the outer upper edge of the frame body 30 so as to be freely bendable, as shown in Figure 10.

[0058] The length and width of the valve body 201 are 1 cm to 3 cm in length and 4 cm to 6 cm in width, and functionally, the outer surface 52 of the excretion bag 50 is raised to expand the internal space of the excretion bag 50, so that excreted feces can fall and be stored in the bottom 55 of the excretion bag 50 without adhering to the part of the outer surface 52 of the excretion bag facing the frame body 30. Cut Anything is fine.

[0059] Therefore, in a pet diaper structure 2 equipped with such a defecation device 200, the lower edge of a flexible valve body 201 is connected to the outer upper edge 30a of the frame body in a bendable manner, and the valve body 201 is in close contact with the outer surface 52 that faces the inner surface 51 of the excretion bag 50 to which the frame body 30 is connected. Therefore, there is no need to engage the tail T of the pet P with the valve body 201, which minimizes stress on the pet when wearing the pet diaper structure 2, makes it easy to put on and take off the pet P, and since there is no need for a tail insertion hole in the excretion bag 50, there is an effect of preventing the risk of the bag being damaged through this hole.

[0060] In this embodiment, the vertical width of the inside surface 51 of the excretion bag is longer than the vertical width of the outside surface 52 of the excretion bag. That is, the length from the lower welding surface 56 to the top of the excretion bag 50 on the inside and outside of the excretion bag 50 is different between the inside and outside of the excretion bag 50, with the peripheries of the inside surface 51 and the outside surface 52 of the excretion bag welded together.

[0061] 11, the inner surface length TI from the lower welding surface 56 to the upper edge 30a of the frame is longer than the outer surface length TO from the lower welding surface 56 to the upper edge 201a of the valve body. By making the inner surface length TI greater than the outer surface length TO, the inner surface 51 of the excretion bag 50 can be in a state where it bulges downward.

[0062] In particular, since the valve body 201 is in close contact with the outer surface 52 opposite the inner surface 51 of the excretion bag 50 to which the frame body 30 is fixed, the valve body 201 functions as a support that expands the internal space of the excretion bag 50, making it possible to expand the internal space of the excretion bag 50 regardless of the movement of the pet P's tail T.

[0063] This has the effect of forming a sufficient space between the frame body 30 and the outer surface 52 of the excretion bag to allow the feces 18 that has been dropped into the excretion bag 50 through the excretion window 14 to smoothly fall to the bottom 55 of the excretion bag 50 (see Figure 12). As a result, the inside of the outer surface 52 of the excretion bag 50 that faces the frame body 30 is not soiled, so there is no risk of the feces 18 soiling the area around the anus of the pet P, which has the effect of improving the hygienic environment when the pet P is wearing the diaper.

[0064] To further enhance this effect, the outer surface 52 of the excretion bag may be raised upward so that the position where the valve body 201 is attached is slightly closer to the center of the outer surface 52 of the excretion bag. This increases the difference between the inner surface length TI and the outer surface length TO of the excretion bag 50, allowing the inner surface 51 to bulge downward more significantly.
