Description

[Technical Field]

[0001] This invention relates to a drawstring-type drainer garbage bag that has an opening for inserting food waste and the like that can be closed in a drawstring shape. [Background technology]

[0002] Conventionally, food waste generated during cooking or after meals has been collected in draining garbage bags stored in draining containers such as kitchen sinks. Once the moisture content of the food waste has been reduced, the draining garbage bags are transported and collected in garbage bags for waste collection. It is preferable to seal the opening during transportation. The opening can be sealed by tying the garbage bag itself. However, since it is necessary to leave space around the opening for tying, the capacity of the draining garbage bag to store food waste is reduced. To prevent this reduction in storage capacity, the opening can be sealed by tying it into a drawstring shape with string, but this requires separate preparation of the string. Therefore, draining garbage bags with pre-installed strings (see, for example, Patent Documents 1 and 2) and draining garbage bags with lids have been proposed (see, for example, Patent Document 3).

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 4-127287 [Patent Document 2] Japanese Utility Model Application Publication No. 7-8302 [Patent Document 3] Utility Model Registration No. 3209288 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, a tie string is woven into a tubular fabric woven on a circular loom. While Figure 2 of Patent Document 1 presumably forms a ring at the end of the string to make it easier to grip and pull by hand, there is no explanation as to how the ring-shaped portion is formed. It is assumed that forming the ring by weaving is impossible. In Patent Document 2, a string is attached to the outer periphery of the top opening of a drainer garbage bag, but both ends of the string must be tied to form a knot, and then the knot must be pulled to close the opening. In Patent Document 3, a lid seal is formed on both the front and back sides of the opening, allowing the opening to be closed by overlapping two lid seals. However, it is questionable whether overlapping two lid seals can adequately close the opening.

[0005] The object of this invention is to provide a drawstring-type drainer garbage bag whose opening can be easily closed with a string. [Means for solving the problem]

[0006] The device is a roughly cylindrical draining garbage bag with an opening on one side, When not in use, it folds flat, A string is provided around the opening so that the opening can be tied in a drawstring shape to close it. A joint with the end of the string is formed on one end side of the folded opening, The joint has a notch that can be separated from the periphery of the opening This is a drawstring-type draining garbage bag characterized by the above.

[0007] The present invention is also characterized in that the bottom of the cylindrical drainer garbage bag is formed as a gusseted bottom, and when the gusseted bottom is expanded, a bottom surface is formed so that the bag can stand on its own.

[0008] In addition, the present invention is characterized in that the cylindrical draining garbage bag is made of nonwoven fabric. [Effects of the Invention]

[0009] According to this invention, the opening can be easily closed with the string by pulling the joint.

[0010] In addition, this device allows the bottom of the bag to be placed over a kitchen sink, forming a freestanding draining garbage bag with the opening at the top. Food waste generated during cooking or after meals can be placed through the opening, and the drawstring can be used to close the opening like a drawstring bag, making it easy to use and transport for food waste collection.

[0011] In addition, according to this invention, the draining garbage bag is made of nonwoven fabric, so it can efficiently drain moisture and other substances from the collected food waste. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 is a front view of a drawstring-type drainable garbage bag 1 according to one embodiment of the present invention. [Figure 2] FIG. 2 is a right side view showing the drawstring-type drainer garbage bag 1 of FIG. 1 with the front and rear directions exaggerated. [Figure 3] FIG. 3 is a perspective view showing the state in which the joint 2b of the drawstring drainer garbage bag 1 of FIG. 1 is pinched by hand and separated from the opening 2. FIG. [Figure 4] FIG. 4 is a perspective view showing the drawstring-type drainer garbage bag 1 of FIG. 1 in a state where it stands upright. [Figure 5] FIG. 5 is a perspective view showing the drawstring drainer garbage bag 1 of FIG. 1 being carried together with collected food waste. DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below with reference to Figures 1 to 5. 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]

[0014] 1 and 2 show the front and right side views, respectively, of a drawstring drainer garbage bag 1 in an unused state, which is one embodiment of the present invention. For ease of explanation, the front-to-back direction in the right side view is exaggerated in the front view. The drawstring drainer garbage bag 1 is formed by folding a rectangular nonwoven fabric sheet 6 roughly in half to form a cylindrical shape, with an opening 2, a bottom 3, a left edge 4, and a right edge 5. When unused, the bag is folded flat. The folded side forms the bottom 3, which is folded inward at a predetermined width to form the gusseted bottom 3a. Both ends of the fold form the opening 2, with folds 2a formed by folding inward from the periphery. The opening 2, the gusseted bottom 3a, and the left and right edges 4 and 5 between them form the left and right sides 4a and 5a, respectively, where the side edges of the folded nonwoven fabric sheet 6 are integrally welded together. A string 7 is provided within the fold margin 2a of the opening 2, which can be used to tie the opening 2 into a drawstring shape to close it, and a joint 2b where the end of the string 7 meets is formed on one end of the folded opening 2. The joint 2b has a slit 2c that can be separated from the periphery of the opening 2. The periphery of the opening 2 needs to be folded inward to secure the string 7. The inward folding is the result of consideration of the production process design and the convenience of everyday use for customers.

[0015] Figure 3 shows how the joint 2b of the drawstring drainer garbage bag 1 can be pinched by hand to separate it from the opening 2. The joint 2b has a slit 2c that can be separated from the periphery of the opening 2, so if you pinch the edge of the opening 2 with one finger 9 and pinch and pull the joint 2b with the other finger, the joint 2b will separate from the drawstring drainer garbage bag 1. By further pulling the pinched joint 2b, the opening 2 can be easily and securely closed with the string 7.

[0016] Figure 4 shows the drawstring 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 bag becomes self-standing, with the opening 2 facing upward. Food waste generated during cooking or after a meal can be placed through the opening 2 and closed into a drawstring shape with the string 7, making the drawstring drainer garbage bag 1 easy to use and transport for collecting food waste.

[0017] Figure 5 shows the drawstring drainer garbage bag 1 of Figure 1 being carried together with collected food waste. In this embodiment, a string 7 is attached to the opening 2, forming a joint 2b at the end of the string 7, and the joint 2b has a slit 2c that allows it to be separated from the periphery of the opening 2. The drawstring drainer garbage bag 1 can be used to collect food waste and to carry the bag, as the joint 2b can be separated and pinched by hand, and the opening 2 can be closed with the string 7, making it even easier to use and transport.

[0018] The drawstring drainer garbage bag 1 of this embodiment can be made to stand on its own, eliminating the need for a drainer such as a triangular corner, but it can also be used with a drainer. When used with a drainer, the gusseted bottom 3a does not need to be provided. Furthermore, while the drawstring drainer garbage bag 1 is made of nonwoven fabric, it can also be made of a resin film with drainage holes. The string 7 can be made of either inelastic thread or elastic rubber. [Explanation of symbols]
