Garbage Separation Storage Disposal Fabric folding bag.

Abstract

[Problem] To provide a wastewater dust and debris filtering bag that can be manufactured at low cost using existing materials and conventional equipment. [Solution] A heat-sealable nonwoven fabric with a width of 500 mm is folded several times on both sides, an elastic cord is inserted into the fold, and the edges are sewn together while the elastic cord is stretched to more than twice its original length. The entire piece is then folded to a width of 25 mm to form an intermediate product. After being wound up using a pulley for a 25 mm wide belt, full layer, transverse, and double welding is performed every 110 to 150 mm in length, and the piece is cut between the double welds to form the final product. When the elastic cord-bound sections on both sides are pinched open with both hands, it becomes a bag that can be used as a triangular basket in a kitchen sink or a general cylindrical dustbin.

Description

Technical Field

[0001] A garbage bag that can separate the dirt mixed in the sewage in the kitchen, sink, etc. and dispose of it as dry garbage. Conventionally, bags for this purpose have been difficult to store, use, and discard, and were expensive, making housewives cry.

Background Art

[0002] The base material can be roll-folded, string-attached, welded, and cut with a recycled non-woven fabric and a rubber string, and no new equipment is required.

Problems to be Solved by the Invention

[0003] It is desirable that the fibers of the base recycled non-woven fabric be thermoplastic and pre-heat-rolled so that dimensional stability and folding are easy. It is important that the rubber string is integrated with the fabric in the fully stretched state, and for this reason, devices such as hemming are important.

Means for Solving the Problems

[0004] The base material is a heat-sealable non-woven fabric. Therefore, two rolls of the base material are provided, and the base material between the two rolls is in a tensioned state and its both edges are folded twice in the longitudinal direction. The rubber strings in the fully stretched state supplied from the rubber string devices on both sides are inserted between the folds. Furthermore, two sewing machines for hemming the rubber strings are provided on both edges between the two rolls of the base material, and the rubber strings must be woven into the base material in the fully stretched state. For this reason, the base material with the rubber strings woven on both edges is folded back in the longitudinal direction at a width of 25 mm in the fully stretched state to form a strip shape.

Effects of the Invention

[0005] When the rubber string woven parts on both sides are opened with both hands, a bag shape with a diameter of 6 to 20 cm and a depth of 15 to 18 cm is formed. This is suitable for the triangular basket in the sink of the household kitchen and for a general cylindrical dust bin.

Best Mode for Carrying Out the Invention

[0006] If a white heat-sensitive cloth and a colorless rubber string are used for the base material, it can also be used for washing and storing food ingredients because of its clean feeling.

Example 1

[0007] Elastic cords are attached to both edges of a heat-fusible nonwoven fabric in their most stretched state, and the entire structure is then folded to a width of 25 mm. Double transverse full-layer fusion is performed at a length of 350 mm. After shortening, the fabric is cut between the double transverse fusion lines to obtain one bag with a length of 125 mm. [Industrial applicability]

[0008] In various everyday situations, there are other options besides rubber bags with a diameter of 6-20 cm that can be used to filter out dust and debris from wastewater cheaply and easily, and are also convenient for disposal. These include breathable bags and dustproof caps. [Brief explanation of the drawing]

[0009] [Figure 1] This shows a heat-sealable nonwoven fabric with vertical folds along both edges. [Figure 2] Figure 1 shows a cross-sectional view. [Figure 3] An elastic cord is inserted into the fold, and the cord is secured in its most stretched state. [Figure 4] Furthermore, folds have been made along the entire width at 25mm intervals. [Figure 5] This is the shape after cutting at the cross-sectional, full-layer fused double-wire section, resulting in the most relaxed state.

Claims

[Claim 1] The left and right edges of a roll of heat-melting nonwoven fabric (750mm wide in Figure 1) are folded several times (Figure 2), an elastic cord is passed through the folds (Figure 3), and the elastic cord is sewn while still stretched twice its original length, and the whole is folded to a width of 25mm to form the intermediate product (Figure 4). This is then wound up using a 25mm wide belt pulley, and all layers are re-welded every 150mm, and cut between the re-welds to form the finished product (Figure 5). This is a device that uses simple materials, ordinary processing, and an unusual process to provide an unusual garbage collection device at a low cost.
