Description

The present invention relates to a device for holding a bag in the air, a bag, and a method of attaching the bag. In particular, it can be optimally used as a device for receiving feces of dogs.

The device that holds the bag includes a trash can, garbage receiver (triangular corner), and a device that catches dog droppings in the air. In many of these devices, the main body and frame keep the bag open, and the bottom of the bag is grounded on the main body and the ground to release the weight of the garbage on the bag and prevent the bag from falling. there is
When the bag is held in the air and is not grounded anywhere, there is a method of attaching the bag to the main body or the frame using some kind of tool, or a method of processing the bag itself and attaching it to the main body or the frame.

The following methods have been proposed for devices that are carried around and receive dog feces directly in the air.
Patent Document 1 discloses a method of firmly attaching a bag by sandwiching the bag between a frame and a bag retainer.
Patent document 2 attaches a special bag closed with a ring rubber to the side of the frame.
In Patent Document 3, a non-slip provided on the frame and a clip at the base of the handle are used to hold a part of the bag on the frame.

JP 2012-000006 JP 2003-079264 JP 2009-296985

In the method of Patent Literature 1, the bag is attached to the frame using a "part for pressing the bag against the frame." With this method, even if the bag receives excrement, it is held by the frame and is held, so it does not fall off the frame. Since it is located on the outside, the part holding down the bag can become dirty if it fails to catch feces.

In the method of Patent Literature 2, a special bag that is closed with an annular rubber is used to attach the bag to the frame. The tighter the bag is attached to the frame, the more difficult it becomes to attach the bag, because the ring rubber with a stronger contraction force is required. Bags that are specialized for routine activities such as dog defecation are costly.

Patent Literature 3 discloses a method of attaching a bag to a frame by using both a non-slip surface on the frame body and a clip provided on a handle. An example of using a rubber-like projection provided at the tip of the frame is described as the anti-slip.
In the method of holding the bag in Cited Document 3, the frame and non-slip rubber-like projections are hidden in the bag, so that the bag does not get dirty with excrement. However, when the anti-slip function deteriorates due to dust or aging, the bag cannot be held. On the other hand, since the surface of the new non-slip frame has a non-slip surface, it is difficult to attach and detach the bag.
The typical bag attachment method (Fig. 4) used for these prior art devices results in the outer side of the bag contacting the ground when the feces are caught in the bag, depending on the position of the small dog and the dog when excreting. The outside of the bag may become dirty.

In addition, although it is not in the patent literature, "paper bags that can be flushed with feces into flush toilets" are commercially available in order to respond to the desire to dispose of collected feces as soon as possible. This paper bag has a double structure with a water-soluble paper bag on the outside and a plastic bag on the inside because it is premised that the feces that have fallen to the ground will be collected by hand through the bag.
When collecting excrement that has fallen to the ground, foreign matter such as sand and dry grass easily adheres to the excrement, which may damage the flush toilet.

For this reason, it is desirable to use the "paper bag that can be flushed with feces into the flush toilet" by attaching it to a device that directly receives dog feces in the air. However, in order to attach it to the device of the prior document 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 easy to replace the easily damaged water-soluble paper bag. is not.
In addition, when walking with multiple dogs or defecation multiple times in one walk, it is not possible to overlap the bags with the conventional method of attaching the bag, so remove the bag and attach a new bag each time it receives feces. Work is necessary and troublesome.

The present invention has been made in view of the problems of the prior art. To provide a fixture, a bag, and a method for attaching the bag for solving at least one of the problems that the frame does not get dirty even when the bag is worn, the easily damaged paper bag can be attached and detached, and a plurality of bags can be attached to one tool. aim.

A method for attaching a bag according to claim 1 for solving the above-mentioned problems is a device having a frame for forming and maintaining a space for receiving an object in the bag, and a handle attached to the frame for holding the frame in the air. opening the opening of the bag, inserting the frame into the bag so that the frame is substantially horizontal, and moving the portion of the bag located above the frame below the frame through the inside of the frame. The bag is attached to the frame while forming a space for receiving an object in the bag by moving the frame.

A device for holding a bag according to claim 2 for solving the above-mentioned problems comprises: a frame for forming and maintaining a space for receiving an object in the bag; a handle attached to the frame for holding the frame in the air; At least one projection for fixing the bag is formed on the portion of the frame on the opposite side of the frame from the position where the handle is attached, and the projection is a rod-shaped projection with a rounded end that protrudes from the frame by 7 mm or more. It is characterized by

"The part of the frame opposite to the position where the handle is attached" refers to the part that does not belong to the part where the handle is attached when the frame is divided in two in the direction perpendicular to the direction of the handle so that the areas are equal. If there are more than one handle, there will be more than one "portion of the frame on the side opposite to the position where the handle is attached", but this refers to all of them.
Projections with rounded ends are bar-shaped or plate-shaped projections with rounded ends to prevent holes from being made in plastic bags, as plastic bags are prone to tearing.
As shown in FIG. 1, the rod-shaped protrusions include those made of wire and shaped like rods or plates.

The bag according to claim 3 for solving the above-mentioned problem has two ends of the opening formed by closing the opening of the bag so that the edges of the bag are aligned so that the distance from either end of the opening is 1 cm or more in a direction parallel to the opening. In addition, it is characterized in that all of the openings are linearly bonded up to an arbitrary point within a range of 1/3 of the length of the openings, or the openings are partially bonded with an interval of 5 cm or less.
Bonding the openings means welding, fusing, bonding, or the like using heat, an adhesive, a seal, or the like so that the bonded openings are not easily opened.

A device for holding a bag according to claim 4 for solving the above-mentioned problems comprises: a frame forming and maintaining a space for receiving an object in the bag; a handle attached to the frame for holding the frame in the air; A clip capable of partially closing the opening of the bag is connected to the frame or the handle via a string-like object.
The cord-like thing may be anything that connects things together, such as a metal spring, a plastic coil, or a rubber cord.

The action and effect of the method of attaching the bag of claim 1 will be described with reference to FIG.
According to the first method of attaching the bag, the frame is inserted into the inside of the bag (FIG. 2(a)), and the bag located above the substantially horizontal frame is moved downward through the inside of the frame. A space for receiving an object is thereby formed, and the bag is held by the frame (FIG. 2(b)). In the method of attaching the bag according to claim 1, since the frame is inside the bag, the frame does not get dirty, and the object can be received outside the bag.

The method of removing the bag attached by the method of claim 1 is to pinch the lower end of the opening of the bag (part C in FIG. 2) with your fingers and remove the "bottom part that receives the object (part A in FIG. 3)". The bag can be easily removed by moving the top end of the frame upward (in the direction of G in FIG. 3) so as to pass under it.
At this time, the inside and outside of the bag are exchanged so that the clean inside becomes the outside, making it easy to handle even after removing from the frame. In addition, since the bag is removed by peeling it off from the outside, the bags can be stacked and attached, and since the inner bag is covered with the outer bag, it does not get dirty.
In addition, the characteristics of receiving items on the outside of the bag and the fact that the inside and outside of the bag are replaced when the bag is removed are the characteristics of the commercially available "washable bag", which has a double structure of a water-soluble bag on the outside and a plastic bag on the inside. It is convenient to use a paper bag that can be flushed down the toilet.

As described above, the attachment method of the bag according to claim 1 is simple and completely different from the conventional attachment method, so that there are various effects, but the retention of the bag is unstable.
When the bag attached by the method of claim 1 receives an object, forces X, Y and Z act as shown in FIG. 2(b). When the conditions are met, the portion of the bag Q receives this force X, so that the bag supports the bag and the bag is held by the frame. The bag is out of the frame.
In order to stably hold the bag attached to the frame by the method of claim 1, the device and bag of claims 2 to 4 are conceived.

Before explaining the operation of the device of claim 2, the principle of holding the bag with the protrusions will be explained.
A plastic bag with a straight welded bottom has two closed corners (A, B in FIG. 2). The phrase "two directions are closed" means that the corner B of the bag in FIG. 2A is closed in two directions around the corner B of the side BA and the side BC.

Even if a stick with a round tip is inserted into a bag with two corners, and the tip of the stick touches the corner of the bag and the bag is pulled with your fingertips, the two corners of the bag are closed. The tip of the stick does not move from the corner. If the bag is made of a soft material, the rod will wrap around the bag, making it even harder to move. This is also the case around corners.
However, if the tip of the rod is placed away from the corner and pulled in the same way, the tip of the rod slips along the surface of the bag and disengages from the bag because it is not closed in either direction.
As described above, the principle of holding the bag according to claim 2 does not involve making scratches or holes in the bag to hold it, so the tips of the projections are rounded.

In the device for holding a bag according to claim 2, the bag can be held by using the above-described principle and by locating rod-shaped projections formed on the frame at or around the corners of the bag.
Also, a typical bag has at least two corners, and a bag with gussets has four corners. A bag can be held more stably by using a frame with a plurality of projections and locating them at a plurality of corners at the same time.
In the conventional method of attaching the bag to the frame as shown in Fig. 4, the bag is inserted from above the frame and the periphery of the opening of the bag is fixed to the frame. The projections formed on the frame cannot be positioned.

A method of attaching a bag using claim 1 to a device for holding a bag of claim 2 will be described. 1 is inserted from the opening of the bag (same as FIG. 2(a)), and the projections of the frame are positioned around the corner B of the bag as shown in FIG. 3(a). Rotate the frame so that it is horizontal while pushing down, then push down through the inside of the frame the portion of the bag containing the other corner A located above the frame. As a result, the protrusion 1 can be positioned at or around the corner B of the bag to fix the bag to the frame and to form a space for receiving objects.
The length of the rod-shaped projections is determined by the size of the frame and the shape of the frame (substantially triangular, elongated oval, etc.). It is desirable to have projections with a length of at least 7 mm or more, preferably 1 cm or more.

A method of removing the bag attached by the method of claim 1 will be described with reference to FIG. Grab the lower end C of the opening E of the bag with your fingers and move it in the direction of arrow G so as to pass under the "bottom part of the bag that received the object (around the corner A that was not used for holding)", and move it from the frame. When you lift it up, the bag attached to the projection comes off, so you can easily remove the bag from the frame. At this time, the inside and outside of the bag are exchanged so that the clean inside becomes the outside, making the bag easy to handle.

When the bag is attached to the device for holding the bag of claim 2 of the present invention by the method of claim 1, the corner B of the bag is fixed to the projection of the frame and the corner A of the bag does not move, so the deep bag (AD In the case of a bag with a long gap, even if the end D of the opening of the bag is not fixed, the gap AD is long, so the end D is unlikely to come off from the frame.
However, when using a bag with a shallow bottom (a bag with a short A-D interval), or after receiving an object with the bag, the device was shaken back and forth, and a force was applied between the A-D intervals of the bag that would pull the edge D of the bag. In this case, the edge D of the bag may come off the frame.
In such a case, as shown in FIG. 3(a), the opening can be reliably maintained by fixing the periphery of the end D of the bag around the handle with a clip or the like.

The bag of claim 3 of the present invention is a bag in which a part of the opening of the bag is pasted together by welding, adhesion, adhesive tape, etc. from the beginning, and the bag can be held on the frame by supporting the bag with the bag.
The method and action of attaching the bag 5g to the frame 2g of the present invention will be described with reference to FIG. As shown in FIG. 8, the frame is inserted through the opening K of the bag 5g and positioned substantially horizontally. The bag is rotated around the frame so that the edge S of the opening where the bags are stuck together is positioned at the lowest position below the frame.
Next, the corner P of the bag located above the frame and its periphery are pushed down through the inside of the frame to the edge S of the opening.

When an object is received in the bag in this state, since the edge S of the opening is glued together, the corner P of the bag 5g does not come off from the opening, and a force in the X direction is applied to the edge S of the opening. The bag is pulled in the Y1 and Z1 directions. In addition, since the bag is pulled in the Y and Z directions, the forces are balanced and the bag supports the bag.

When only a part (L1, L2) of the opening of the bag is pasted together as shown in FIG. ), the bag may slip through. In claim 3, the distance between the end S and the glued part (between S and L2 in FIG. 8) is 5 cm at maximum, so when 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 greater than 3.18 cm, the bag will not fall through. If the frame is smaller than this, the distance between the end S and the pasted part (between S and L2 in FIG. 8) may be narrowed. -L2).

A method for removing the held bag is to grasp the welded portion L1 of the opening of the bag in FIG. Alternatively, the bag 5e can be easily removed from the device by separating the parts L1 and L2, which are joined together by welding the opening of the bag, with fingers and moving the edge S of the opening in the direction G.

A device for holding a bag according to claim 4 of the present invention is obtained by replacing the welding of the opening of the bag according to claim 3 with a clip. Therefore, the action of holding the bag on the frame and the position of the clip are the same as in claim 3.
The device for holding the bag according to claim 4 does not require preprocessing of the bag or special device.

By using the method for attaching the bag according to claim 1 of the present invention, the frame is not easily soiled because the bag is attached by putting the frame in the bag. When the bag is removed, the inside and outside of the bag are exchanged so that the clean inside becomes the outside, making the bag easy to handle.
In addition, according to the method of attaching the bag of claim 1, a plurality of bags can be stacked in advance and attached to the device, and can be used sequentially from the outside. need not be installed frequently. In addition, since the current bag completely covers the bag to be used next time, there is no risk of soiling the next bag even if the feces are not received.

Furthermore, by using the bag attaching method of Claim 1, it is possible to easily attach and detach a "flushable toilet bag" which is a double layer of a water-soluble paper bag and a plastic bag on the market. Since the water-soluble paper bag, which is particularly susceptible to breakage, is simply moved downward through the inside of the frame from above the frame, the load on the paper bag is reduced compared to the conventional mounting method, and the bag can be mounted without being damaged.
According to the present invention, the "paper bag that can be flushed down the toilet" can directly receive excrement, preventing the toilet from malfunctioning due to foreign objects such as pebbles, soil, and dead leaves.

According to the bag attachment method of claim 1 of the present invention, the bag can be held on the frame using the tools and bags of claims 2 to 4.
In the device for holding a bag according to claim 2, the rod-shaped projections provided on the frame allow the bag to be attached and detached easily, and the projections of the frame can hold the bag.
However, depending on the shape of the bag, the end of the bag on the handle side may come off the slide-down frame, so it is necessary to clip the end of the bag on the handle side.
The bag is also inexpensive because it can use a general plastic bag on the market. The structure of the frame is also simple, so it is hard to damage, and there is no influence of dust or deterioration over time.

The bag of claim 3 is a bag in which a part of the opening of the bag is welded. The bag can be attached and detached easily, and no special device or frame is required to support the bag with the bag.
The bag itself uses a special bag with a part of the opening welded in advance, but it can be manufactured at a low cost because it is a simple process.

The device for holding the bag of claim 4 comprises a clip for partially closing the opening of the bag for supporting the bag with the bag and holding it to the frame. No special device, frame or bag processing is required other than the clip. For this reason, it is easy to use and the attachment and detachment of the bag can be done easily.

In addition, the device and bag for holding the bag claimed in the claims of the present application can be used not only for dog excrement but also for a frame that replaces a trash can or a triangular corner in a kitchen. In the frame that replaces the triangular corner, the draining bag can be held in the air only by the frame, so it is easier to clean than the triangular corner.

As described above, according to the present invention, the attachment and detachment of the bag can be easily performed, the bag can be held in the frame without being affected by aging due to the simple method and structure, the equipment and the bag are not stained, and the cost is high. It is possible to provide equipment and bags with unprecedented convenience, such as attaching and detaching fragile paper bags, and attaching multiple bags to one equipment.

The bag used in this embodiment is a waterproof plastic bag made of polyethylene, polypropylene, or the like. As shown in FIG. A bag with corners. Such bags are readily available at home centers and supermarkets. In this embodiment, for the sake of explanation, the four corners of the bag when the bottom of the bag is straight and the opening is closed are referred to as A, B, C, and D, of which A and B are the corners of the bottom of the bag. , C and D are the edges of the opening of the bag.

The size of the bag to be used is selected in consideration of the size of the frame and the purpose of use. In this embodiment, since the frame is circular with a diameter of 12 cm, a commercially available bag with a width of 23 cm (between AB) and a depth of 35 m (between AD and BC) is used. It is not limited to bag size. Note that the figure does not have this size or proportion due to space limitations.
The frame of the example is made of a wire with a thickness of 3 mm that does not easily bend under normal force.
Numerical values, materials, etc. in this embodiment are examples, and do not limit the claims unless otherwise specified.

(Example 1)
Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4. FIG. Example 1 is an example of a device for receiving dog excrement corresponding to claim 2 . It will also be explained that this device produces an effect by the method of attaching the bag of claim 1.

As shown in FIG. 1, the device of Example 1 is a device for receiving dog excrement in which a frame 2 is connected to a handle 4 via a handle 3. As shown in FIG. The frame 2 is a circular frame with a diameter of 12 cm and is made of a wire with a circular cross section and a thickness of 3 mm. A rod-like projection 1 is formed by bending the wire itself forming the frame 2 on the part of the frame 2 opposite to the handle 3 with respect to the center of the frame 2.例文帳に追加A rod-shaped projection 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 a space for the bag to receive the feces and keeps the feces from falling.

A method of attaching the instrument and the bag in Example 1 will be described with reference to FIGS. 2 and 3. FIG. The bag 5 used in Example 1 is a general plastic bag that is commercially available and has 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 has one corner each at end A and end B of the bottom.

A specific method for attaching the bag is to insert the frame 2 from the opening E of the bag 5 as shown in FIG. 2(a). Next, with the projection 1 of the frame 2 positioned at or near the corner B of the bag, when the frame 2 is placed substantially horizontally, the corner A of the bag 5 is above the frame 2, and the end C of the opening is positioned above the frame 2. The bag 5 is rotated about the frame 2 as necessary so that it is positioned below the frame 2. - 特許庁
Further, when the corner A of the bag 5 located above the frame 2 and its surroundings are pushed down through the inside of the frame 2 below the frame 2 (direction F in FIG. 2(b)), as shown in FIG. 3(a). A space capable of receiving feces is formed while the protrusion 1 of the frame 2 is positioned at or near the corner B of the bag.

Actions and effects of the first embodiment will be described with reference to FIG. When feces are received by the bag 5 attached by the method of Example 1, a downward force X is applied around the corner A, and the corner B is pulled in the direction Y of the corner A. Since the corner B of the bag 5 is closed in two directions centering on the side AB and the side BC, the periphery of the corner B of the pulled bag 2 is wrapped around the projection 1 and held. For this reason, the corner A cannot be lowered any further.

In addition, in a bag whose depth (between AD) is sufficiently longer than the bottom (between AB) of the bag 5, there is enough room even if it is pulled in the Z direction to some extent. I can't come off. However, if there is no margin in the depth of the bag (between A and D), or if a force is applied between A and D by shaking the instrument back and forth to pull the end D of the bag, the end D of the bag will move away from the frame. may come off. If there is such a risk, as shown in FIG. 3(a), the opening is maintained by closing the portion D with a clip so as to wind it around the handle. In addition, since the clip is located under the part near the handle, it is difficult to get dirty with feces.

Commercially available plastic bags with gussets have four corners although the bottom of the bag is welded in a straight line. A polygonal bag, such as a bag with a triangular bottom, also has multiple corners. Such a bag can also be held by the frame using the corners in the same manner as in the first embodiment by using the above-described method of attaching the bag.
In order to clarify the difference in action between the bag attaching method of claim 1 and the conventional bag attaching method, a conventional bag was attached to the apparatus of Example 1 shown in FIG. FIG. 4 shows how force is applied when an object is received by the bag 5 .

In a conventional method of attaching a bag, after passing the bag 5 through the opening of the frame 2, the bag 5 is attached to the frame 2 by folding the opening E of the bag 5 so as to surround the frame 2.例文帳に追加In this method, as shown in FIG. 4, the protrusions 1 of the frame 2 are not around corners A and B of the bag 5, so when an object enters the bag 5 and is pulled downward (in the X direction), the Y and A force in the Z direction is generated, but the bag 5 simply slides on the protrusion 1 and does not catch on, and the bag 5 slides down from the frame 2 and comes off.
Even if the bag 5 has corners and the frame 2 has the bar-like protrusions 1, the conventional bag mounting method in which the protrusions 1 are not located near the corners cannot hold the bag 5.例文帳に追加

In addition, in the conventional method of attaching the bag, the object is received inside the bag, but in the method of attaching the bag of claim 1 of the present invention, the object is received outside the bag.
The bag that can be used to flush the collected excrement into the toilet has a double structure with a water-soluble paper on the outside and a plastic bag on the inside. In order to attach this bag to the device of Example 1 by the conventional method shown in FIG. 4, it is necessary to exchange the outer and inner bags. By using the bag attachment method of claim 1 of the present invention, there is no need to replace the inner bag and the outer bag, and the double bag can be inserted into the frame and simply pushed downward through the frame to the bag located above the frame. Can be installed.

A method of removing the bag 5 attached by the method of claim 1 from the frame 2 of the first embodiment will be described with reference to FIG. Remove the clip 6, grasp the lower end C of the opening E of the bag 5 with your fingers, move it in the direction of the arrow G so as to pass under the corner A of the bag 5, and lift it above the frame 2 to find that it is wrapped around the protrusion 1. Since the bag 5 is removed from the protrusion 1, the bag 5 can be easily removed from the frame 2. - 特許庁Since the inside and outside of the bag are exchanged at this time, it is convenient to use the double-structured bag that can be flushed down the toilet.
In addition, since the bag that receives feces can be removed in this manner, a plurality of bags can be stacked and attached to the device, and the outer bag can be used first. It is convenient because it is not necessary to attach the bag repeatedly during a walk for dogs that defecate many times in one walk or for multiple dogs.

As described above, the device for receiving dog excrement of Example 1 can easily attach and detach the bag, and has a function of holding the bag while having a simple structure that does not use a fixing device for the bag or a non-slip. The device does not get dirty even if it fails to catch feces, it does not require a special bag, and it can be attached by stacking multiple bags. In addition, water-soluble paper bags that can be flushed down the toilet and bags can be stacked and attached, providing unprecedented convenience.

(Modification of Example 1)
5 and 6 show modified examples of the protrusions shown in the first embodiment.
In FIG. 5(a), the projection 1a is formed vertically upward with respect to the horizontally placed frame 2a. In FIG. 5(b), the protrusion 1b is formed toward the center of the frame 2b.
When the bag is attached to the frames 2a and 2b of FIGS. 5(a) and 5(b) in the same manner as in Example 1, the projections 1a and 1b of the frames 2a and 2b are positioned at or near the corners of the bag. be able to. Therefore, when an object enters the bag and is pulled downward, the bag is wrapped around the projections 1a and 1b and held by the same action as in the first embodiment.

FIG. 6(a) shows a modification in which two projections 1c are adjacent to the tip of the frame 2c. Gusseted bags have two adjacent corners at each end of the bottom of the bag. The manner of attachment of the bag is similar to that of Example 1, but a modified frame allows each projection to be positioned around two adjacent corners or corners of the gusseted bag. This allows the bag to be held more stably than with a single protrusion.
FIG. 6(b) has two projections 1d separated from the frame 2d on the opposite side of the handle 3d. As for the method of attaching the bag, the left and right corners at the bottom of the bag are positioned on the left and right protrusions 1d, respectively. Then, the bag above the frame is moved downward through the inside of the frame to secure a space for receiving the object.
In FIG. 6(b), as in FIG. 6(a), two projections can be positioned at or around two corners, so that the bag can be held more stably than with one projection.

(Example 2)
Example 2 will be described with reference to the three views shown in FIG. Example 2 is a device corresponding to claim 2 of the present invention, which is a holder that can be used as a substitute for a triangular corner used for draining garbage in the kitchen. FIG. 7(a) is a front view of the holder of Example 2, (b) is a top view, and (c) is a right side view.
As shown in FIGS. 7A and 7B, the holder of Example 2 has a frame 2e that maintains a space for the bag to receive garbage and prevents the bag from falling, and a handle 3e that has a suction cup 7 that sticks to the sink. are connected through The frame 2e has a rounded, substantially triangular shape when viewed from above. A projection 1e is formed at the corner of the holder on the opposite side from the handle 3 of each suction cup 7, and a projection 1f is formed near the handle 3 of each suction cup 7. It is installed diagonally upward.

The bag used in Example 2 is a bag with many small holes used for draining food waste or a bag made of non-woven fabric that allows water to pass through, and has two corners at the bottom of the bag.
The attachment method of the bag is the same as the attachment method shown in FIG. 6(b) shown in the modified example of the first embodiment. position each. A bag positioned above the substantially horizontal frame 2e is pushed down through the inside of the frame to secure a space for receiving garbage.

The action of the garbage holder of Example 2 will be described. When garbage is put into the bag attached by the above-described method, the bag is pressed against the projections 1e formed at the corners of the frame so as to wrap around the bag and hold the bag. For this reason, the other two projections 1f near the suction cup 7 are not only subjected to the force of lowering the bag, but also the force affected by the projections 1e at the corners is newly added, and the projections 1f are pressed so that the bag is wrapped around them. Therefore, the opening of the bag can be maintained without the bag coming off the frame.

The method of removing the bag from the frame 2e involves grasping a part of the opening of the bag attached to the frame 2e with a finger, passing under the bag that received garbage, and pulling the bag outside the protrusion 1f adjacent to the nearby suction cup 7. You can easily remove the bag with the garbage inside by lifting it up so that it passes through.
As described above, the garbage bag holder of the second embodiment has a simple structure and can hold the bag in the air, so that the kitchen garbage bag does not come into contact with the sink. This makes it easy to clean the sink and has a high drainage effect. In addition, compared to conventional triangular corners, the equipment does not get dirty, and it is easy to attach and detach the bag.

(Example 3)
Example 3 will be described with reference to FIG. Example 3 is a bag corresponding to claim 3 of the present invention, which is used by being attached to a device for receiving feces of a dog. The bag 5g is a processed general 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. In the bag of Example 3, the L1 and L2 portions around the opening are 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 portion separates when the opening K of the bag is pulled slightly to the left and right.

The device for receiving excrement in Example 3 may be of any type as long as it has a frame for holding the bag. As an example, the device of Example 1 shown in FIG. As shown in FIG. 8, this is an instrument in which a frame 2g is 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 a wire with a circular cross section and a thickness of 3 mm. The frame 2g holds the bag 5g by forming a space for the bag 5g to receive feces.
As shown in FIG. 8(a), the bag is attached by inserting the frame 2g of the device for receiving dog excrement from the large opening K of the bag, and placing the frame 2g substantially horizontally as shown in FIG. 8(b). , while keeping the end S of the bag at the bottom, push down the plastic bag 5g above the frame 2g downward (in the direction of F) so as to pass through the inside of the frame 2d, and position it near the periphery of the end S. Attach the bag by

Actions and effects of the third embodiment will be described with reference to FIG.
As shown in FIG. 8, in Example 3, L1 and L2, which are part of the opening of the bag, are welded in advance.
When the bag 5g is attached to the frame 2g and feces are received as shown in FIG. 8(b), a force is applied in the X direction in FIG. 8(b). This force is applied to the peripheral portion of the edge S of the opening and becomes a pulling force in the Y1 direction and the Z1 direction. In addition, since the weight X of excrement pulls the bag in the Y and Z directions as well, the forces are balanced, and the bag 5g is held by the frame 2g without slipping down. In addition, for the bag 5g that receives feces, the gap around the edge S of the opening (between S and L2, between L1 and L2) is as narrow as 2 cm, and the weight is added to the peripheral part of the edge S, and the downward movement of the bag 5g. Since the force closes the opening instead of widening, the bag 5g does not pass through the gaps around the edge S (between S and L2 and between L1 and L2).

Also, the method of removing the bag 5g from the frame 2g is to grasp the L1 portion in FIG. 8(b) with fingers, and move the bag P forward (in the direction of G in FIG. 3(a)) so that the bag P passes through the opening K of the bag. move to Alternatively, the bag 5g can be easily removed from the device by separating the welded portions L1 and L2 of the opening of the bag with fingers and moving the edge S of the opening forward.
In this way, by using the bag 5g of Example 3 and using the method of attaching the bag according to claim 1 of the present invention, the bag receiving the object can be held in the frame without using a clip or a special frame. Easy to put on and take off the bag from the frame. In addition, since the processing of the bag 5g is also a simple one in which a part is welded, the cost can be suppressed.

(Example 4)
Example 4 will be described with reference to FIGS. 9 to 11. FIG. Example 4 is a device corresponding to claim 4 of the present invention, which is a device for receiving dog feces.
The device of Example 4 is, as shown in FIG. 9, a device in which a frame 2h is connected to a handle 4h through a handle 3h, and a clip 6 is tied to the handle 3h through a string 8 having a length of 10 cm. The frame 2h is a circular frame with a diameter of 12 cm and is made of a wire with a circular cross section and a thickness of 3 mm. The frame is used to form a space for the bag to receive feces, and to hold the bag after receiving feces. Unlike the instrument of Example 1, there is no projection on the frame, but it has a clip 6 connected to the handle 3h with a string 8. - 特許庁

A method of attaching the bag of the present invention will be described with reference to FIG. The bag 5 used in Example 4 is the same commercially available general plastic bag as in Example 1.
Attach the bag by the method of claim 1, close the opening of the bag (part E in FIG. 2) as shown in FIG. 10, and create a new opening H with a length of about 3 cm at the lower end of the opening The opening E is clipped with a clip 6 as shown. When fastened, the opening E of the bag is divided into a small opening H and a large opening K. The lower end of the opening H is J for explanation.
As an example, the clipping position is 3 cm from the edge S, but if the frame is circular as described later, the size of the frame should be used as a guide because the bag will not fall off if it is within 1.5 times the diameter of the frame. You can decide where to hold it.

The method of removing the bag held by the device of Example 4 will be explained with reference to FIG. Then the bag 5 can be removed from the instrument.
In Example 4, instead of the bag being welded in Example 3, the bag is closed with a clip, so the effect is the same as in Example 3. As shown in FIG. 11, even if the opening H is too wide and the bag 5 passes through the opening H, it 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, the perimeter of the frame is (3.14 x WL), and if the length of the opening H is HL, the perimeter of the opening H is (2 x HL), so (3.14 x WL )>(2×HL), and approximately 1.5×WL>HL. If the length HL of the opening H is 1.5 times or less the diameter of the frame, 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. It doesn't need to be opened wide and clipped, so it stops in the middle without slipping down.

In the fourth embodiment, the bag 5 can be easily held by the frame 2h by using the clip 6 in the bag attachment method of claim 1 of the present invention. Moreover, the bag 5 can be easily removed from the frame 2h by removing the clip 6. - 特許庁
Since the clip 6 is tied to the handle 3h with a string 8, it is difficult to lose it, and the operator can concentrate on the work after removing the bag 5 and the control of the dog.
