Abstract
Description
[Technical Field]
[0001] This invention relates to a freestanding draining garbage bag that can stand on its own in the kitchen and eliminates the need for a drainer. [Background technology]
[0002] Conventionally, food waste generated during cooking or after meals has been collected in draining garbage bags stored in a draining container such as a kitchen sink. Once the moisture content has been reduced, the draining garbage bags are collected in a garbage bag for waste collection. Fine particles of garbage that are discharged from the draining garbage bags along with the moisture adhere to and accumulate in the draining container, making it necessary to clean it after repeated use. To eliminate the need for draining containers, freestanding draining garbage bags have been proposed that can stand on their own in a kitchen sink or other place to collect food waste (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 7462893 [Patent Document 2] Japanese Patent Application Publication No. 2022-161749 Summary of the Invention [Problem to be solved by the invention]
[0004] Patent Document 1 discloses a free-standing draining garbage bag made from a rectangular nonwoven fabric sheet. The bag has an opening with a folded edge around the perimeter, a gusseted bottom of a predetermined width, and both side sections integrally welded to both ends of the folded edge and the gusseted bottom. This free-standing draining garbage bag can be made to stand on its own by expanding the gusseted bottom. However, the unwelded outer periphery around the opening exposes the folded edge of the nonwoven fabric, which may get caught on the surroundings of a kitchen or other space during use or transportation. Patent Document 2 discloses a draining garbage bag whose gusset can be expanded to form a rectangular tube with a flat bottom that can stand on its own. Water is drained through drainage holes in the sides of the bag after it is upright. However, it is expected that it will require considerable effort to make the bag stand on its own in a rectangular tube shape.
[0005] SUMMARY OF THE INVENTION The object of the present invention is to provide a freestanding draining garbage bag that is easy to use and transport for collecting food waste. [Means for solving the problem]
[0006] This device is made by folding a rectangular nonwoven fabric sheet in half, On both sides, folds are made inward from the perimeter to form openings. The folded side is folded inward at a specified width to form a gusseted bottom. The opening, the gusset bottom, and the area between them are formed by the side edges of the folded nonwoven fabric sheet being integrally welded on both sides, When the gusset bottom is expanded, it becomes the base and can stand on its own. This is a self-standing draining garbage bag characterized by the above features.
[0007] The present invention is also characterized in that a string capable of closing the opening is provided within the fold of the opening. [Effects of the Invention]
[0008] According to this invention, when the bottom surface formed by expanding the gusseted bottom is placed on the kitchen sink, it becomes a free-standing draining garbage bag with an opening at the top. Food waste generated during cooking or after meals can be poured through the opening, making it a free-standing draining garbage bag that is easy to use and transport for collecting food waste.
[0009] In addition, according to the present invention, the opening can be closed with a string attached to the opening, making it even easier to use and transport for collecting food waste. [Brief explanation of the drawings]
[0010] [Figure 1] FIG. 1 is a front view of a freestanding draining garbage bag 1 according to one embodiment of the present invention. [Figure 2] FIG. 2 is a right side cross-sectional view showing the freestanding drainer garbage bag 1 of FIG. 1 with the front-to-rear direction exaggerated. [Figure 3] FIG. 3 is a perspective view showing the freestanding drainer garbage bag 1 of FIG. 1 in a state where it stands on its own. [Figure 4] FIG. 4 is a perspective view showing the self-standing draining garbage bag 1 of FIG. 1 being carried together with collected food waste. DETAILED DESCRIPTION OF THE INVENTION
[0011] An embodiment of the present invention will be described below with reference to Figures 1 to 4. In each figure, corresponding parts are given the same reference numerals, and duplicate explanations will be omitted. Parts not shown in the figure being described may be referred to by reference numerals shown in other figures. [Example]
[0012] 1 and 2 show the front and right-side cross-sectional views, respectively, of a freestanding drainable garbage bag 1 according to one embodiment of the present invention. For ease of explanation, the front-to-back direction in the right-side cross-sectional view is exaggerated. Freestanding drainable garbage bag 1 is formed by folding a rectangular nonwoven fabric sheet 6 roughly in half to have an opening 2, a bottom 3, a left edge 4, and a right edge 5. The folded side becomes the bottom 3, which is folded inward at a predetermined width to form a gusseted bottom 3a. Both ends of the fold become the opening 2, and a fold strip 2a is formed by folding inward from the periphery. The opening 2, the gusseted bottom 3a, and the left edge 4 and right edge 5 between them form the left side 4a and right side 5a, which are both sides formed by integrally welding the side edges of the folded nonwoven fabric sheet 6 together. A string 7 is attached within the fold strip 2a of the opening 2, allowing the opening 2 to be closed.
[0013] Figure 3 shows the freestanding drainer garbage bag 1 of Figure 1 in a self-standing state. When the bottom surface formed by expanding the gusseted bottom 3a is placed on a kitchen sink 8, the freestanding drainer garbage bag becomes a self-standing drainer garbage bag with the opening 2 facing upward. Food waste generated during cooking or after meals can be placed through the opening 2, making the freestanding drainer garbage bag 1 easy to use and transport for collecting food waste.
[0014] 4 shows the state in which the freestanding draining garbage bag 1 of FIG. 1 is being carried together with collected food waste. In the freestanding draining garbage bag 1 of this embodiment, the opening 2 can be closed with the string 7, making it easier to use for collecting food waste and to carry it.
