Description

[Technical field]

[0001] The present invention relates to an apparatus for holding a bag containing an object in the air, and to a method for attaching the bag, and in particular to an apparatus for catching dog feces. [Background technology]

[0002] Devices that hold bags include garbage cans, food waste receptacles (triangular corners), devices that catch dog feces in the air, etc. Many of these devices use a body or frame to keep the bag open, and the bottom of the bag touches the body or the ground to release the weight of the garbage on the bag and prevent the bag from falling. If the bag is to be held in the air and not grounded anywhere, there are several methods, such as attaching the bag to the main body or frame using some kind of tool, or modifying the bag itself and attaching it to the main body or frame.

[0003] The following methods have been proposed for portable devices that directly catch dog feces in the air: Patent Document 1 describes a method of firmly attaching a bag by clamping the bag between a frame and a bag holder. Patent Document 2 discloses a special bag that is clamped with a rubber ring and attached to the side of the frame. Patent Document 3 discloses a device that uses a non-slip surface on the frame and a clip at the base of the handle to hold part of the bag to the frame. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication 2012-000006 [Patent Document 2] Patent Publication No. 2003-079264 [Patent Document 3] Patent Publication No. 2009-296985 Summary of the Invention [Problem to be solved by the invention]

[0005] In the method of Patent Document 1, the bag is attached to the frame using a "part that holds the bag to the frame." With this method, even if the bag receives feces, it is held by the frame and will not come off the frame and fall off, but it takes time to attach and detach the bag, and since the part that holds the bag is located on the outside of the bag, there is a possibility that the part that holds the bag will become dirty if the feces are not received.

[0006] The method of Patent Document 2 uses a special bag that is constricted by a rubber ring and is attached to the frame. The tighter the bag is attached to the frame, the stronger the rubber ring needs to be to contract, making it more difficult to attach the bag. The use of special bags for everyday activities such as dog defecation is problematic in terms of cost.

[0007] Patent Document 3 describes a method of attaching a bag to a frame by using a non-slip surface of the frame and a clip on the handle in combination. An example of using a rubber-like protrusion on the tip of the frame as a non-slip surface is described. In the bag holding method described in Reference 3, the frame and the rubber-like protrusions of the non-slip surface are hidden by the bag, so they do not get dirty with feces. However, if the non-slip function deteriorates due to dust or aging, it will no longer be able to hold the bag. Conversely, the surface of the frame with the non-slip surface in a new state makes it difficult for the bag to slip, making it difficult to attach and remove the bag. With the typical bag attachment method used for these prior art devices (Figure 4), when collecting feces in the bag, the outside of the bag may come into contact with the ground depending on the position of the dog when it is small or when the dog is defecundating, which may cause the outside of the bag to become dirty.

[0008] Also, although not mentioned in the patent literature, a paper bag that can be flushed down the toilet with feces in it is commercially available to meet the demand for disposing of collected feces as quickly as possible. This paper bag is designed to be collected by catching the feces that have fallen to the ground through the bag with your hands, so it has a double structure with a water-soluble paper bag on the outside and a plastic bag on the inside. When collecting feces that have fallen to the ground, foreign matter such as sand and dead grass tend to adhere to the feces, which could damage the flush toilet.

[0009] For this reason, it is desirable to attach the "paper bag that can be flushed down the toilet with the excrement" to a device that directly receives dog excrement in the air. However, in order to attach it to the device in the prior art using the conventional attachment method, it is necessary to replace the outside with a plastic bag and the inside with a water-soluble paper bag before attaching it to the frame, and it is not easy to replace the water-soluble paper bag, which is easily damaged. In addition, when walking multiple dogs or when a dog defecates multiple times during a single walk, the conventional method of attaching bags does not allow the bags to be stacked, so it is necessary to remove the bag and attach a new one every time a dog defecates, which is a hassle.

[0010] The present invention has been made with attention to the problems of the conventional technology, and aims to provide an apparatus, a bag, and a method for attaching the bags that solve at least one of the problems described above, which are that the bag can be easily attached and detached, the bag can be held on the frame without being affected by changes over time, the frame does not become dirty even if feces or the like is not caught, even easily damaged paper bags can be attached and detached, and multiple bags can be attached to one apparatus. [Means for solving the problem]

[0011] The method of attaching a bag of claim 1 for solving the above problem is a method of attaching a bag to an implement having a frame for forming and maintaining a space in the bag to receive an object, and a handle attached to the frame to hold the frame in the air, characterized in that the opening of the bag is opened, the frame is inserted into the bag to make the frame approximately horizontal, and the part of the bag positioned above the frame is moved downward beyond the frame through the inside of the frame, thereby forming a space in the bag to receive an object and attaching the bag to the frame.

[0012] The bag-holding device of claim 2 for solving the above problem is characterized in that it comprises a frame for forming and maintaining a space in the bag for receiving objects, a handle attached to the frame for holding the frame in the air, and at least one protrusion for fixing the bag formed on a part of the frame opposite the attachment position of the handle, the protrusion being a rod-shaped protrusion with a rounded tip that protrudes 7 mm or more from the frame.

[0013] "The part of the frame opposite the pattern attachment position" refers to the part that does not include the pattern attachment position when the frame is divided into two at right angles to the pattern direction so that the area is equal. If there are multiple patterns, there will be multiple "parts of the frame opposite the pattern attachment position", and this refers to all of those parts. A protrusion with a rounded tip is a rod- or plate-shaped protrusion with a rounded tip to prevent a hole being made in the bag, as plastic bags are prone to tearing if a hole is made in them. The rod-shaped protrusions include those made of wire and having a rod-like or plate-like outer shape, as shown in FIG.

[0014] The bag of claim 4 for solving the above problem is characterized in that the opening is completely or partially pasted in a straight line from either one of the two ends of the opening created by closing the bag so that the edges of the opening match, to an arbitrary point within a range of 1 cm or more in a direction parallel to the opening and within 1 / 3 of the length of the opening, or with an interval of 5 cm or less. Bonding the opening means fusing, welding, or adhering the bonded opening using heat, an adhesive, a seal, or the like so that the bonded opening does not open easily.

[0015] The bag-holding device of claim 3 for solving the above problem is characterized by a frame that forms and maintains a space in the bag for receiving objects, a handle attached to the frame to hold the frame in the air, and a clip that can close part of the opening of the bag, connected to the frame or the handle via a string-like object. The string-like object can be anything that can be used to connect things together, such as a metal spring, a plastic coil, or a rubber band.

[0016] The operation and effect of the bag attachment method of claim 1 will be described with reference to FIG. The bag attachment method of claim 1 involves inserting a frame into the bag (Fig. 2(a)), and moving the bag, which is located above the roughly horizontal frame, downward through the inside of the frame. This creates a space for receiving objects, and the bag is held in the frame (Fig. 2(b)). With the bag attachment method of claim 1, the frame is inside the bag, so it does not get dirty, and objects are received on the outside of the bag.

[0017] To remove a bag attached according to the method of claim 1, pinch the bottom end of the opening of the bag (part C in Fig. 2) with your fingers and move it above the tip of the frame (direction G in Fig. 3) so that it passes under the "bottom part that receives the object (part A in Fig. 3)", and the bag will easily come off. At this time, the inside and outside of the bag are swapped, and the clean inside becomes the outside, making it easy to handle even after removing it from the frame. Also, since the bag is removed by peeling it off from the outside, the bags can be stacked and installed, and the inner bag will not get dirty because it is covered by the outer bag. Furthermore, the features of receiving items on the outside of the bag and of the inside and outside of the bag being interchangeable when the bag is removed are convenient for use with commercially available "paper bags that can be flushed down the toilet with feces inside," which have a double structure of a water-soluble bag on the outside and a plastic bag on the inside.

[0018] As mentioned above, the bag attachment method of claim 1 is simple and has various effects because it is a completely different attachment method from the conventional one, but the retention of the bag is unstable. When the bag attached according to the method of claim 1 receives an object, forces X, Y, and Z act as shown in Fig. 2(b). When the conditions are right, part of the bag Q receives this force X, so the bag is supported by the frame and the bag is held in place, but when the conditions are slightly different, part A that received the object slides down from opening E of the bag, causing the bag to come off the frame. The devices and bags described in claims 2 to 4 have been devised to stably hold the bag attached to the frame using the method described in claim 1.

[0019] Before explaining the operation of the device of claim 2, the principle of holding the bag with the protrusion will be explained. A plastic bag with a linearly welded bottom has corners that are closed on two sides (A and B in Figure 2). Closed on two sides means that corner B of the bag in Figure 2(a) is closed on two sides, centered on corner B on sides BA and BC.

[0020] If you insert a round-tipped stick into a bag with two corners, and grab the bag with your fingertips while the tip of the stick is touching the corner of the bag, the tip of the stick will not move from the corner because the corner is closed on two sides. If the bag is made of a soft material, the bag will wrap around the stick, making it even more difficult to move. This is also true around the corners. However, if you place the tip of the stick away from the corner and pull in the same way, the bag is not closed in either direction, so the tip of the stick slides along the surface of the bag and comes out of the bag. The principle of holding the bag in claim 2 is not to hold the bag by scratching or drilling holes in it, so the tips of the protrusions are rounded.

[0021] The bag-holding device of claim 2 utilizes the above-mentioned principle, and is able to hold the bag by positioning the rod-shaped protrusions formed on the frame at or near the corners of the bag. In addition, a typical bag has at least two corners, and a bag with a gusset has four corners. By using a frame with multiple protrusions and positioning it at multiple corners at the same time, the bag can be held more stably. In addition, in the conventional method of attaching a bag to a frame as shown in Figure 4, the bag is inserted from above the frame and the periphery of the opening of the bag is fixed to the frame, so the protrusions formed on the frame cannot be positioned at the corners of the bag or their surroundings.

[0022] The method of attaching a bag using claim 1 to the bag-holding device of claim 2 is described below. The frame with the protrusions shown in Fig. 1 is inserted into the opening of the bag (same as Fig. 2(a)), and the frame is rotated so that it is horizontal while positioning the protrusions of the frame around corner B of the bag as shown in Fig. 3(a), and then the part of the bag including the other corner A located above the frame is pushed down through the inside of the frame. This positions protrusion 1 at or around corner B of the bag, and fixes the bag to the frame, while forming a space for receiving objects. In addition, since the positioning of the rod-shaped protrusion at or near the corner of the bag is influenced by the size and shape of the frame (roughly triangular, elongated oval, etc.), it is desirable for the length of the rod-shaped protrusion to be at least 7 mm from the frame, and preferably 1 cm or more.

[0023] A method for removing the bag attached according to the method of claim 1 will be explained with reference to Figure 3. Grasp the bottom end C of the opening E of the bag with your fingers, move it in the direction of arrow G so as to go under the "bottom part of the bag that received the object (around the corner A that was not used for holding)," and lift it above the frame, and the bag will come off from the protrusions, allowing you to easily remove the bag from the frame. At this time, the inside and outside of the bag will be swapped, and the clean inside will become the outside, making the bag easy to handle.

[0024] When a bag is attached to the bag-holding device of claim 2 of the present invention in the manner of claim 1, corner B is fixed to the protrusion of the frame, so corner A of the bag does not move either. Therefore, in the case of a deep bag (bag with a long distance between AD), even if edge D of the bag opening is not fixed, edge D is unlikely to come off the frame because the distance between AD is long. However, if a bag with a shallow bottom (a bag with a short distance between AD) is used, or if the device is shaken back and forth after receiving an object in the bag, applying a force between AD of the bag that pulls on end D of the bag, there is a possibility that end D of the bag will come off the frame. In such a case, the opening can be reliably maintained by wrapping the edge D of the bag around the handle with a clip or the like, as shown in FIG. 3(a).

[0025] The bag of claim 4 of the present invention is a bag in which part of the opening of the bag is welded, glued, or pasted with adhesive tape from the beginning, and the bag can be held in place by supporting it with the bag. The method of attaching the bag 5g to the frame 2g of the present invention and its function will be described with reference to Figure 8. As shown in Figure 8, the frame is inserted into the opening K of the bag 5g and positioned approximately horizontally. The bag is rotated around the frame as an axis so that the edge S of the opening where the bag is attached is at the lowest position below the frame. Next, the corner P of the bag located above the frame and its surroundings are pushed down through the inside of the frame to the edge S of the opening.

[0026] When an object is placed in the bag in this state, the edge S of the opening is glued together, so corner P of bag 5g does not fall out of the opening, and a force in the X direction is applied to the edge S of the opening, pulling the bag in the Y1 and Z1 directions. The bag is also pulled in the Y and Z directions, so the forces are balanced and the bag supports itself.

[0027] When only a portion (L1, L2) of the opening of the bag is glued together as in Figure 8, the gap between the edge S and the glued part (between S and L2 in Figure 8) created by the glueing may cause the bag to slip through as shown in Figure 11(b). In claim 4, the gap between the edge S and the glued part (between S and L2 in Figure 8) is a maximum of 5 cm, so if considered as a circle, it is the same as a circle with a circumference of 10 cm and a diameter of 3.18 cm. Therefore, if the frame is a circle with a diameter larger than 3.18 cm, the bag will not slip through and fall. If the frame is smaller than this, the gap between edge S and the joined part (between S-L2 in Figure 8) should be narrowed, and the gap between edge S and the joined part (between S-L2 in Figure 8) should be determined according to the size of the frame.

[0028] The method for removing the held bag is to grasp the welded portion L1 of the opening of the bag in Figure 8 with the fingers and move the portion of the bag P in the direction G so that it passes through the opening K of the bag. Alternatively, the portions L1 and L2 that have been welded together at the opening of the bag can be pulled apart with the fingers and the edge S of the opening can be moved in the direction G, whereby bag 5e can be easily removed from the device.

[0029] The bag-holding device of claim 3 of the present invention is a device in which the welding of the opening of the bag of claim 4 is replaced by a clip. Therefore, the function of holding the bag on the frame and the position of fastening the clip are the same as claim 4. The device for holding the bag as claimed in claim 3 does not require any prior processing of the bag or any special device. Effect of the Invention

[0030] When using the bag attachment method of claim 1 of the present invention, the frame is inserted into the bag before the bag is attached, so the frame is less likely to get dirty. When removing the bag, the inside and outside of the bag are swapped, and the clean inside becomes the outside, making the bag easy to handle. In addition, in the bag attachment method of claim 1, multiple bags can be attached to the device in advance and used in sequence from the outside, so there is no need to attach bags frequently during walks, even for dogs that defecate multiple times per walk or when walking multiple dogs. Also, since the current bag completely covers the next bag to be used, there is no risk of the next bag becoming dirty even if the current bag misses the feces.

[0031] Furthermore, by using the bag attachment method of claim 1, it is easy to attach and remove commercially available "flushable bags" that are made of two layers of water-soluble paper bags and plastic bags. The water-soluble paper bags, which are particularly prone to breakage, are simply moved downward through the inside of the frame, which places less strain on the paper bags compared to conventional attachment methods and allows them to be attached without breaking. According to the present invention, feces can be collected directly in a "paper bag that can be flushed down the toilet," preventing the toilet from breaking down due to foreign objects such as pebbles, soil, and dead leaves.

[0032] According to the bag attachment method of the present invention, the bag can be held on the frame by using the devices and bags of the second to fourth claims. The bag-holding device of claim 2 has a rod-shaped protrusion on the frame that allows the bag to be easily attached and detached, and the bag can be held by the protrusion on the frame. However, depending on the shape of the bag, the end of the bag on the handle side may slip out of the frame, so it may be necessary to secure the end of the bag on the handle side with a clip. The bags are inexpensive because they can be made from ordinary plastic bags available on the market. The frame structure is simple, so it is not easily damaged, and it is not affected by dust or deteriorated over time.

[0033] The bag in claim 4 has a part of the opening welded, etc. The bag can be easily attached and detached, and no special device or frame is required to support the bag. The bag itself is a special bag with part of the opening already welded, but since this is a simple process, it can be manufactured inexpensively.

[0034] The bag-holding device of claim 3 includes a clip that closes a part of the opening of the bag to support the bag and hold it in the frame. No special equipment, frame, or bag processing is required other than the clip. This makes it easy to use and easy to attach and remove the bag.

[0035] In addition, the bag-holding device and bags claimed in this application can be used not only for dog feces, but also as a frame to replace a garbage can or a kitchen sink. In a frame to replace a sink sink, the draining bag can be held in the air by just the frame, making it easier to clean than a sink sink sink, and the draining bag does not stick to the sink, so it does not soil the sink and has a high draining effect.

[0036] As described above, the present invention provides an apparatus, bag, and bag attachment method that are convenient in a way that has not been seen before, allowing bags to be easily attached and removed, allowing the bags to be held in the frame without being affected by changes over time due to the simple method and structure, preventing the apparatus and bags from becoming dirty, eliminating the need for costly bag processing, making it possible to attach and remove even easily damaged paper bags, and allowing multiple bags to be attached to one apparatus.

[0038] The bags used in this embodiment are waterproof plastic bags made of polyethylene or polypropylene, and as shown in Fig. 2, the bottom of the bag is welded in a straight line and has at least two corners. Such bags are readily available at home improvement stores and supermarkets. For the sake of explanation in this embodiment, the four corners of the bag when the bottom is straight and the opening is closed will be referred to as A, B, C, and D, with A and B being the corners of the bottom of the bag and C and D being the edges of the opening of the bag.

[0039] The size of the bag to be used is selected taking into consideration the size of the frame and the purpose. In this example, the frame is circular with a diameter of 12 cm, so a bag with a width (between AB) of 23 cm and a depth (between AD and BC) of 35 cm that is commonly sold is used, but this is only an example and is not limited to this size of bag. Note that the figure does not show these sizes or proportions due to space restrictions. The frame in the embodiment is formed from a 3 mm thick wire that does not bend easily under normal force. The numerical values ​​and materials in the present embodiment are merely examples and do not limit the claims unless otherwise specified. EXAMPLES

[0040] Example 1 A first embodiment of the present invention will be described with reference to Figures 1 to 4. The first embodiment is an example of a device for receiving dog feces that corresponds to claim 2. It will also be described how the device produces an effect by the bag attachment method of claim 1.

[0041] As shown in Figure 1, the device of Example 1 is a device for catching dog feces, in which a frame 2 is connected to a handle 4 via a handle 3. The frame 2 is a circular frame with a diameter of 12 cm, and is made of wire with a circular cross section and a thickness of 3 mm. At the part of the frame 2 opposite the handle 3 with respect to the center of the frame 2, the wire that forms the frame 2 itself is bent to form a rod-shaped protrusion 1. The rod-shaped protrusion 1 protrudes 15 mm from the frame 2 in the centrifugal direction (the direction opposite to the direction toward the center of the frame). This frame 2 maintains the space for the bag to catch the feces, and holds the feces so that they do not fall out.

[0042] The method of attaching the device and the bag in Example 1 will be explained with reference to Figures 2 and 3. The bag 5 used in Example 1 is a typical commercially available plastic bag, with a width AB of 23 cm and a depth AD of 35 cm. The bottom of the bag is fused in a straight line, and each end A and end B of the bottom has one corner.

[0043] A specific method of attaching the bag is to insert frame 2 into opening E of bag 5 as shown in Fig. 2(a). Next, while positioning protrusion 1 of frame 2 at or near corner B of the bag, rotate bag 5 around frame 2 as necessary so that corner A of bag 5 is above frame 2 and edge C of the opening is below frame 2 when frame 2 is held approximately horizontal. Furthermore, when corner A of bag 5 located above frame 2 and its surrounding area are pushed downward through the inside of frame 2 (in the direction of F in Figure 2(b)), a space capable of receiving feces is formed while keeping protrusion 1 of frame 2 positioned at or near corner B of the bag, as shown in Figure 3(a).

[0044] The action and effect of the first embodiment will be explained with reference to Fig. 3. When bag 5 attached by the method of the first embodiment receives feces, a downward force X is applied around corner A, and corner B is pulled in the direction Y of corner A. Corner B of bag 5 is closed in two directions, centered on sides AB and BC, so the periphery of corner B of the pulled bag 2 is held by wrapping around protrusion 1. As a result, corner A cannot drop any further.

[0045] Furthermore, in bags where the depth (between AD) is sufficiently longer than the bottom (between AB) of bag 5, there is enough room to allow the bag to be pulled to a certain extent in the Z direction, so edge D of the opening will not come off frame 2. However, if there is not enough room in the bag's depth (between AD) or if the tool is rocked back and forth and a force is applied to between AD of the bag that pulls edge D, there is a possibility that edge D of the bag may come off the frame. If there is any risk of this happening, the opening can be maintained by wrapping part D around the handle with a clip to close it, as shown in Figure 3(a). Furthermore, the clip is located under the part close to the handle, so it is less likely to become soiled by feces, etc.

[0046] In commercially available gusseted plastic bags, the bottom of the bag is welded in a straight line, but there are four corners. Bags with polygonal bottoms, such as triangular ones, also have multiple corners. If the above-mentioned bag attachment method is used, such bags can be held to the frame using the corners in the same way as in Example 1. In order to clarify the difference in function between the bag attachment method of claim 1 and the conventional bag attachment method, a conventional bag attachment was performed on the device of Example 1 shown in Figure 1, and the way in which force is applied when an object is received in bag 5 is shown in Figure 4.

[0047] In the conventional method of attaching bags, after passing bag 5 through the opening of frame 2, bag 5 is attached to frame 2 by folding opening E of bag 5 so as to surround frame 2. With this method, as shown in Figure 4, protrusion 1 of frame 2 is not located near corners A and B of bag 5, so when an object is placed in bag 5 and pulled downward (in the X direction), forces in the Y and Z directions are generated, but bag 5 simply slides over protrusion 1 and does not get caught, so bag 5 slides off frame 2 and comes off. Even if bag 5 has corners and frame 2 is provided with rod-shaped projections 1, bag 5 cannot be held in place using a conventional bag attachment method in which projections 1 are not positioned near the corners.

[0048] Furthermore, while conventional bag attachment methods receive objects on the inside of the bag, the bag attachment method of claim 1 of the present invention receives objects on the outside of the bag. The bag that can be used to flush collected feces down the toilet has a double structure with a water-soluble paper outer layer and a plastic bag inner layer, and the water-soluble paper is prone to tearing due to its characteristics. To attach this bag to the device of Example 1 using the conventional method shown in Figure 4, it is necessary to switch the outer and inner bags, but this is difficult because the water-soluble paper is prone to tearing. By using the bag attachment method of claim 1 of the present invention, there is no need to switch the inner and outer bags, and the bag can be attached simply by inserting a frame into the double bag and pushing the bag located above the frame downward through the inside of the frame.

[0049] A method for removing the bag 5 attached according to the method of claim 1 from the frame 2 of embodiment 1 is explained with reference to Fig. 3. After removing the clip 6, the bottom end C of the opening E of the bag 5 is grasped with the fingers, and the bag is moved in the direction of the arrow G so as to pass under the corner A of the bag, and then lifted above the frame 2, whereby the bag 5 wrapped around the protrusion 1 is removed from the protrusion 1, and the bag 5 can be easily removed from the frame 2. At this time, the inside and outside of the bag are switched, which is convenient for using the double-structure bag that can be flushed down the toilet. In addition, since the bag that received the feces can be removed in this way, multiple bags can be attached to the device and used from the outer bag. This is convenient because it eliminates the need to attach bags multiple times when walking multiple dogs or when walking multiple dogs.

[0050] As described above, the dog feces collecting device of Example 1 has the following features: the bag can be easily attached and detached, it has a simple structure without bag fixing devices or anti-slip devices, but has the function of holding the bag, the device does not get dirty even if the feces is not collected, no special bag is required, and multiple bags can be attached in layers. In addition, it is possible to attach water-soluble paper bags or bags that can be flushed down the toilet, which is convenient in a way that has not been seen before.

[0051] (Modification of the first embodiment) Modified examples of the projections shown in the first embodiment are shown in FIGS. In Fig. 5(a), the protrusion 1a is formed in a vertical upward direction relative to the horizontally placed frame 2a, while in Fig. 5(b), the protrusion 1b is formed in a direction toward the center of the frame 2b. 5(a) and 5(b) in the same manner as in Example 1, the protrusions 1a and 1b of the frames 2a and 2b can be positioned at or near the corners of the bag. Therefore, when an object is placed in the bag and pulled downward, the bag is held by being wrapped around the protrusions 1a and 1b in the same manner as in Example 1.

[0052] Fig. 6(a) shows a modified example in which there are two adjacent protrusions 1c at the tip of the frame 2c. The gusseted bag has two adjacent corners at each end of the bottom of the bag. The method of attaching the bag is the same as in the first embodiment, but by using the modified frame, each protrusion can be positioned at two adjacent corners or around the corners of the gusseted bag. This allows the bag to be held more stably than if there was only one protrusion. In Figure 6(b), there are two separate protrusions 1d on a frame 2d on the opposite side of a handle 3d. The method of attaching a bag is to position the left and right corners of the bottom of the bag on the left and right protrusions 1d, respectively. Next, the bag above the frame is moved downward through the inside of the frame to secure a space to receive the object. In FIG. 6(b), similarly to FIG. 6(a), two protrusions can be positioned at two corners or around the corners, so that the bag can be held more stably than if there was only one protrusion.

[0053] Example 2 The second embodiment will be described with reference to the three-sided view shown in Fig. 7. The second embodiment corresponds to claim 2 of the present invention, and is a holder that can be used as a substitute for a triangular corner used to drain kitchen garbage, etc. Fig. 7 (a) is a front view of the holder of the second embodiment, (b) is a top view, and (c) is a right side view. As shown in each drawing in Figure 7, the holder of Example 2 comprises a frame 2e that maintains the space for the bag to receive food waste and holds the bag so that it does not fall out, and suction cups 7 that stick to the sink, which are connected via handle 3e. This frame 2e is a roughly rounded triangle when viewed from above, and a protrusion 1e is formed at the corner of the holder opposite the handle 3 of each suction cup 7, and further a protrusion 1f is provided diagonally upward near the handle 3 of each suction cup 7.

[0054] The bag used in Example 2 is a bag with many small holes used for draining food waste, or a bag made of water-permeable nonwoven fabric, etc., with two corners at the bottom of the bag. The method of attaching the bag is the same as that shown in Fig. 6(b) in the modified example of the first embodiment, and the two protrusions 1e at the corners of the frame 2e are positioned at the two corners or around the corners at the bottom of the bag. The bag located above the roughly horizontal frame 2e is pushed down through the inside of the frame to secure a space to receive food waste.

[0055] The operation of the food waste holder of the second embodiment will now be described. When food waste is placed in the bag attached in the above-mentioned manner, the bag is pressed so as to wrap around the protrusions 1e formed at the corners of the frame, and the bag is held in place. As a result, the other two protrusions 1f near the suction cup 7 are not only subjected to the force lowering the bag, but also receive a new force influenced by the corner protrusions 1e, which presses the bag around the protrusions 1f, and the bag remains open without coming off the frame.

[0056] To remove the bag from frame 2e, grasp part of the opening of the bag attached to frame 2e with your fingers, pass it under the bag that has received the food waste, and lift it up so that it passes over the outside of protrusion 1f adjacent to nearby suction cup 7, and the bag can be easily removed with the waste still inside. As described above, the garbage bag holder of the second embodiment has a simple structure, but can hold the bag in the air, so the food waste bag does not come into contact with the sink. This makes it easy to clean the sink and has a high draining effect. In addition, compared to conventional sink corners, the equipment does not get dirty, and the bags can be easily attached and removed.

[0057] Example 3 Example 3 will be described with reference to FIG. 8. Example 3 corresponds to claim 4 of the present invention, and is a bag attached to a tool for collecting dog feces. Bag 5g is a processed ordinary plastic bag, and has four corners P, R, S, and T as shown in FIG. 8(a), where S and T are the edges of the opening. The bag of Example 3 has L1 and L2 parts around the opening welded by heat. The distance from the edge S of the opening to L2 and the distance from L2 to L1 are 2 cm. The welded area is made small so that the welded part will separate when the opening K of the bag is pulled a little strongly to the left and right.

[0058] The feces receiving device of Example 3 may be any device that has a frame for holding the bag, but as an example, we will use the device of Example 1 in Figure 1 with the protrusions removed. As shown in Figure 8, this device has a frame 2g connected to a handle 4g ​​via a handle. The frame 2g is a circular frame with a diameter of 12 cm, and is made of wire with a circular cross section and a thickness of 3 mm. This frame 2g forms a space for the bag 5g to receive the feces and holds the bag 5g. The method of attaching the bag is to insert the frame 2g of the dog feces receiving device into the large opening K of the bag as shown in Figure 8(a), and then, as shown in Figure 8(b), hold the frame 2g approximately horizontally. With the end S of the bag positioned at the lowest point, push the plastic bag 5g above the frame 2g downward (in the direction of F) so that it passes through the inside of the frame 2d, and position the bag near the periphery of the end S to attach the bag.

[0059] The operation and effect of the third embodiment will be described with reference to FIG. As shown in FIG. 8, in the third embodiment, L1 and L2, which are parts of the opening of the bag, are welded in advance. When bag 5g is attached to frame 2g as shown in Figure 8(b) and feces is received, a force is applied in the X direction in Figure 8(b). This force acts on the area around edge S of the opening, pulling it in the Y1 and Z1 directions. The weight of the feces, X, also pulls the bag in the Y and Z directions, so the forces are balanced and bag 5g is held on frame 2g without slipping off. Note that for bag 5g that has received the feces, the gaps around edge S of the opening (between S-L2 and between L1-L2) are only 2 cm apart, which is narrow, and because the weight applied to the area around edge S causes the opening to close rather than widen due to the downward force, bag 5g does not pass through the gaps around edge S (between S-L2 and between L1-L2).

[0060] To remove bag 5g from frame 2g, grasp part L1 in Fig. 8(b) with your fingers and move part P of bag forward (direction G in Fig. 3(a)) so that it passes through opening K of the bag. Alternatively, pull apart the welded parts L1 and L2 of the opening of the bag with your fingers and move edge S of the opening forward, whereby bag 5g can be easily removed from the device. In this way, by using the bag 5g of Example 3 and the bag attachment method of claim 1 of the present invention, the bag that received the object can be held in the frame without using clips or a special frame, and the bag can be easily attached and detached from the frame. In addition, the processing of the bag 5g is simple, with only a portion of it being welded, so costs can be kept down.

[0061] Example 4 A fourth embodiment will be described with reference to Figures 9 to 11. The fourth embodiment is an apparatus according to claim 3 of the present invention, which is an apparatus for receiving dog feces. As shown in Fig. 9, the device of Example 4 has a frame 2h connected to a handle 4h via a handle 3h, and a clip 6 attached to the handle 3h via a string 8 that is 10 cm long. The frame 2h is a circular frame with a diameter of 12 cm, made of wire with a circular cross section and a thickness of 3 mm. This frame is used to form a space for the bag to receive the feces, and to hold the bag after the feces have been received. Unlike the device of Example 1, the frame does not have any protrusions, but has a clip 6 connected to the handle 3h by the string 8.

[0062] The method of attaching the bag of the present invention will be described with reference to Fig. 10. The bag 5 used in the fourth embodiment is the same as the first embodiment, and is a commercially available general plastic bag. The bag is attached using the method of claim 1, the opening of the bag (part E in Fig. 2) is closed as shown in Fig. 10, and the opening E is fastened with clip 6 so that a new opening H of about 3 cm in length is created at the bottom end of the opening. When fastened, the opening E of the bag is divided into a small opening H and a large opening K. For the sake of explanation, the bottom end of opening H is designated as J. As an example, the position for fastening the clip was set to 3 cm from the edge S, but as will be described later, if the frame is circular, the bag will not slip off as long as it is within 1.5 times the diameter of the frame, so the position for fastening the clip can be determined based on the size of the frame.

[0063] The method of removing the bag held by the device of Example 4 is explained with reference to Figure 10. Bag 5 can be easily removed from the device by removing clip 6 holding the opening of bag 5, grasping part J with your fingers and moving it in the direction of arrow G. In the fourth embodiment, the bag is closed by a clip instead of welding as in the third embodiment, so that the operation is the same as that of the third embodiment. As shown in Fig. 11, even if the opening H is too wide and the bag 5 passes through the opening H, the bag will not come off the frame if the perimeter of the opening H is smaller than the perimeter of the frame. If the diameter of the frame is WL, then the circumference of the frame is (3.14 x WL), and if the length of the opening H is HL, then the circumference of the opening H is (2 x HL), so (3.14 x WL) > (2 x HL), or roughly 1.5 x WL > HL. If the length HL of the opening H is 1.5 times the diameter of the frame or less, the bag will not come off the frame. In Example 1, the diameter of the frame is 12 cm, so the length HL of the opening H is 18 cm or less. There is no need to open it this wide to secure it with clips, so it stops halfway without slipping off.

[0064] In the fourth embodiment, as described above, the frame 2h can easily hold the bag 5 by using the clip 6 in the bag attachment method of the first aspect of the present invention. In addition, by removing the clip 6, the bag 5 can be easily removed from the frame 2h. The clip 6 is connected to the handle 3h by the string 8, so that it is difficult to lose, and the user can concentrate on the work to be done after removing the bag 5 and on controlling the dog.
