Abstract
Description
[Technical Field]
[0001] The present invention relates to a trash can, and more particularly to a trash can with a bag stopper that has the function of stopping bags such as plastic bags. [Background technology]
[0002] 2. Description of the Related Art It is common practice to reuse plastic bags or vinyl bags used to carry home products when shopping at supermarkets or the like as garbage bags at home.
[0003] In regard to the above, attempts have been made to store discarded trash in a bag rather than directly in the trash can by providing a bag inside the trash can, and a trash can with a bag stopper is known for this purpose. In such a trash can, the trash does not come into contact with the inner wall of the trash can, so the inside of the trash can is kept clean, and when discarding trash, the bag can be removed from the trash can and discarded as is, making disposal easier.
[0004] A known example of such a trash can with bag fasteners is one that has a number of notches around the top of the trash can for inserting and fastening the handles of bags (Patent Document 1).
[0005] Also known is a trash can in which an annular bag stopper is engaged with the upper edge of the trash can, and the upper part of the bag is sandwiched and held between the trash can and the bag stopper (Patent Documents 2 and 3).
[0006] Furthermore, a trash can is also known that has a bottomed, cylindrical trash can body that narrows downwards and has a ring-shaped protrusion on the inner circumference near the upper edge of the opening, and a ring-shaped bag stopper that has a flange portion on the top, with the lower end of the outer periphery abutting on the ring-shaped protrusion of the trash can body and the peripheral side of the flange abutting on the inner peripheral wall of the container body located on the protrusion, and whose inner periphery is within the size of the inner periphery of the ring-shaped protrusion of the trash can body (Patent Document 4).
[0007] In the above-mentioned trash can, an annular bag stopper is fitted onto the outer periphery of the bag, and the open end of the bag located above the bag stopper is folded back onto the outer periphery of the bag stopper. Then, the bag stopper is engaged with the annular protrusion on the trash can body. This causes the bent part of the folded back part of the bag to be hooked onto the upper end of the bag stopper, and the folded back part is clamped between the outer periphery of the flange of the bag stopper and the inner wall of the trash can body, and between the lower end of the bag stopper and the annular protrusion on the trash can body, thereby fixing the bag inside the trash can body.

[0008] [Patent Document 1] Registered Utility Model No. 3048930 [Patent Document 2] Jippan No. 55-109605 [Patent Document 3] Registered Utility Model No. 3059049 [Patent Document 4] Patent Publication No. 2021-109709 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]
[0009] However, the trash can described in Patent Document 1 has the inconvenience that it can only be used with bags that have handles.
[0010] On the other hand, the trash cans described in Patent Documents 2 and 3 are versatile in terms of bags, but have the inconvenience of not being able to be used for trash cans intended for stacking because the bag stoppers protrude.
[0011] Furthermore, the trash can described in Patent Document 4 solves the above problem, but because the bag is attached by wrapping the bag around the bag stopper, in order to remove the bag containing trash, it was necessary to lift the bag by hand, holding the end of the bag that was covered in dirt and grime. [Means for solving the problem]
[0012] The present invention was created with the aim of providing a trash can with a bag stopper that solves the problems of the prior art. In other words, the trash can with bag stoppers of the present invention comprises an outer frame that contacts the inside of the upper end of the trash can body, and an inner frame that is held in place by a plurality of connecting members with a gap between them on the inside of the outer frame; the trash can with bag stoppers is installed inside the upper end of the trash can body, and the lid has a trash opening and a flange portion that hangs down from the lower end of the opening and is inserted into the inner frame of the bag stopper; the trash can with bag stoppers is characterized in that the flange portion that hangs down from the lid body is inclined inward or the inner frame is inclined outward so that the area of contact between the flange portion that hangs down from the lid body and the inner frame when inserted is reduced.
[0013] The invention described in claim 2 is characterized in that in the trash can with bag stoppers, the bag stoppers are engaged with the opening of the trash can body by a flange portion that protrudes outward from the upper end.
[0014] Furthermore, the invention described in claim 3 is characterized in that, in the above-mentioned trash can with bag stoppers, the trash can body, bag stoppers, and lid body have rectangular cross sections, and connecting members that engage the inner frame with the outer frame are provided at the corners. [Effects of the Invention]
[0015] In the trash can with bag stoppers of the present invention, a plastic or vinyl bag is dropped into the inner frame of the bag stopper as a trash bag (see Figure 5), and then the upper end is folded back and locked between the inner and outer frames, and the bag stopper is fitted inside the upper end of the trash can (see Figure 3).Furthermore, the lid of the trash can is fitted into the bag stopper, so that the trash bag is sandwiched and fixed between the flange part of the lid that is inserted into the inner frame of the bag stopper and the inner frame (see Figures 4 and 6).
[0016] In this case, when removing a garbage bag, after removing the lid, the upper end of the garbage bag, which is folded over and locked between the inner frame and the outer frame, is grasped with the fingers and pulled up; however, the inside of the folded garbage bag is prevented from coming into contact with garbage by the flange portion of the lid body, and the outside is located between the inner frame and the outer frame outside the garbage area, so that garbage and dirt do not stick to the fingertips.
[0017] In addition, attaching a garbage bag is easy because it only requires dropping a plastic bag or vinyl bag into the inner frame of the bag stopper, then folding the upper end back between the inner and outer frames to fasten it.
[0018] Also, as shown in Figure 6, the flange hanging from the lid is tilted inward or the inner frame is tilted outward so that the contact area between the flange hanging from the lid and the inner frame is small, and the garbage bag is firmly fixed by point contact between the inner frame and the flange. When the flange is tilted inward, not only is the flange of the lid preventing the inside of the folded garbage bag from coming into contact with garbage, but the bottom edge of the flange does not come into contact with the garbage bag, so it is more completely prevented that garbage traveling down the flange comes into contact with the top edge of the garbage bag and gets on your fingertips.
[0019] Furthermore, in a trash can with bag stoppers where the trash can body, bag stoppers, and lid have rectangular cross sections, if connecting members that engage the inner frame with the outer frame are provided at the corners, it is rational to place the connecting members at the corners where it is difficult to fold the trash bag, as this allows the length of other parts where it is easy to fold to be longer.

[Figure 6] FIG. 10 is a cross-sectional view of the essential parts of the bag stopper with a garbage bag attached and covered. BEST MODE FOR CARRYING OUT THE INVENTION
[0021] A specific embodiment of the trash can with bag stoppers of the present invention will be described below with reference to the accompanying drawings. Figure 1 shows the components of the trash can with bag stoppers of the present invention, and here shows a trash can with a rectangular cross section. This trash can with bag stoppers is composed of a plastic trash can body 1, a plastic bag stopper 2, and a plastic lid 7.
[0022] The trash can body 1 is formed on the premise that it can be stacked, and is configured as a cylindrical shape with a circular cross section and a bottom that tapers downward.
[0023] The bag stopper 2 is formed in a rectangular ring shape, with a rectangular ring-shaped outer frame 3 that contacts the inside of the top end of the trash can body 1 and a rectangular ring-shaped inner frame 4 that is concentric with and spaced apart from it, and the two are connected by connecting members 5. These connecting members 5 are a pair of plate-like members that are installed at the four corners of the bag stopper. This arrangement allows the connecting members to be located at the corners where it is difficult to fold the trash bag, thereby allowing for longer lengths in other areas where it is easier to fold, which is a rational solution. Furthermore, because the connecting members 5 are a pair of plates, any excess upper end of the trash bag at these points can be pushed into the gap with your fingertips, making it easy to keep the trash bag together.
[0024] The bag stopper 2 is fastened to the opening of the trash can body 1 by a flange portion 6 that protrudes outward from the upper end of the outer frame 3.
[0025] The lid 7, which is fitted onto the bag stopper 2, has a garbage insertion opening in the center of the top plate 8 and a flange 9 hanging down from the bottom of the opening. This flange 9 is inserted into the inner frame 4 of the bag stopper 2 and is tapered inward, tapering downward. This reduces the contact area between the flange 9 and the inner frame 4, and the garbage bag P, which is sandwiched and fixed between the inner frame and the flange, is firmly fixed by point contact. Note that the same effect can be achieved by tilting the inner frame 4 outward.
[0026] Of course, the trash can body, bag stopper, and lid may have a circular cross section.
[0027] In the above-mentioned trash can with bag stoppers, a plastic bag or vinyl bag is dropped into the inner frame 4 of the bag stopper 2 as a trash bag P (see Figure 5), and then the upper end is folded back and locked between the inner frame and the outer frame 3, and the bag stopper is fitted inside the upper end of the trash can body 1 (see Figure 3), and then the trash can lid 7 is fitted into the bag stopper, so that the trash bag is sandwiched and fixed between the flange part of the lid that is inserted into the inner frame of the bag stopper and the inner frame (see Figures 4 and 6).
[0028] In this case, when the flange portion 9 is tilted inward, not only is the inside of the folded garbage bag P prevented from coming into contact with garbage by the flange portion of the lid body, but the lower end of the flange portion does not come into contact with the garbage bag, so that garbage traveling down the flange portion is more completely prevented from coming into contact with the upper end of the garbage bag and sticking to fingertips.
