Description

Technical Field

[0001] The invention belongs to the technical field of water-cut nets, and in particular relates to a disposable water-cut net with a pull ring and a manufacturing method thereof. Background Art

[0002] At present, various solutions have been proposed for this type of water-cutting net. Among them, Patent Document 1 (Japanese Patent Publication No. 2006-291688) discloses a drain net with a rope attached to the upper part of the drain net, which makes the disposal work simple and hygienic. In addition, Patent Document 2 (Japanese Patent Publication No. 2003-246404) discloses a water-cutting bag having a water-permeable bag body and a pair of endless rope bodies arranged on the bag body, and the rope bodies are pulled in a specific direction by their respective gripping parts, thereby shrinking the bag body and closing its opening.

[0003] However, from the perspective of simplifying the disposal and replacement work and sanitation, this water-cut net is disposed of together with the foreign matter whenever a certain amount of foreign matter accumulates in the water-cut part, rather than being reused. Therefore, the amount of consumption in households is considerable, and therefore it is sold in packages of about 30 to 100 units per bag on the market. Based on this situation, the water-cut net is in urgent need of reducing costs, and the above-mentioned conventional water-cut nets are all manufactured separately from the water-cut part when the rope is extracted from the garbage receiver of the drain outlet, and the rope is attached to the water-cut part in different processes by means of welding, bonding or braiding.

[0004] Therefore, since the process of adding ropes to the water-cutting parts, which is essential in the manufacture of water-cutting nets, is unstable due to the material properties of the shapes of the water-cutting parts and the ropes, it becomes difficult to automate the additional process in terms of cost, and it can only rely on manual work, which becomes an obstacle to cost reduction. Summary of the invention

[0005] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a disposable water cutting net with a pull ring and a manufacturing method thereof. The method does not require a separate process of adding a rope to the water cutting part, has excellent productivity, and can be extremely low-cost compared to traditional technologies.

[0032] First embodiment: Next, Figure 3 For reference, an embodiment of a method for manufacturing the above-mentioned water-cut net 1 will be described. This embodiment relates to a method for simultaneously manufacturing two water-cut nets 1. The detailed description is as follows.

[0033] First, if Figure 3 As shown in (a), two water-cut parts, namely the first water-cut part 10A and the second water-cut part 10B, are woven in a connected state, and the mother materials 50 of the first telescopic part 20A, the second telescopic part 20B and the first rope part 30A, the second rope part 30B are respectively connected to the opening ends 11A and 11B of the first water-cut part 10A and the second water-cut part 10B. In this embodiment, a circular knitting machine is used for weaving.

[0034] Specifically, first, in the first rope braiding process, only the elastic thread is used to braid the annular structure of the first rope 30A. Here, the diameter of the annularly braided first rope 30A is the same as the diameter of the first telescopic part 20A, the second telescopic part 20B, and the first water-cut part 10A and the second water-cut part 10B.

[0035] Next, in the first stretchable portion braiding step, the first stretchable portion 20A is braided using the elastic thread of the first rope portion 30A from the first other end portion 40A of the looped first rope portion 30A braided in the first rope braiding step. At this time, the inelastic thread of the first water-cut portion 10A is connected.

[0036] Subsequently, in the water-cut portion knitting process, the supply of the elastic thread is stopped, and only the inelastic thread is used to continuously knit the two water-cut portions 10, ie, the tubular structure of the first water-cut portion 10A and the second water-cut portion 10B.

[0037] After the two water-cut portions 10 can be knitted, in the second stretchable portion knitting process, the elastic thread is supplied and the second stretchable portion 20B is knitted continuously from the other end of the second water-cut portion 10B using the inelastic thread and the elastic thread.

[0038] In the second rope braiding process, the supply of the inelastic thread needs to be stopped, and the loop structure of the second rope 30B is braided using the same elastic thread as the second stretchable part 20B from the second other end portion 40B of the second stretchable part 20B. In this way, the two water-cut nets 1 are connected to each other.

[0039] Finally, the products formed by the above process, such as Figure 3 As shown in (b), C is cut from the middle end of the first water cut portion 10A and the second water cut portion 10B, and Figure 3Here, the closing of the cutting parts C and C can be carried out by welding the inelastic line formed by the first water-cut part 10A and the second water-cut part 10B, or by fixing them with an adhesive. The closing means can be arbitrarily selected.

[0040] The manufacturing method includes a first rope weaving step of weaving a first rope portion in a ring shape; a first telescopic portion weaving step of continuously weaving a first telescopic portion from a part of the other end of the ring-shaped first rope portion weaved in the first rope weaving step; a tubular water-cut portion weaving step of continuously weaving two water-cut portions from the other end of the first telescopic portion weaved in the first telescopic portion weaving step; a second telescopic portion weaving step of continuously weaving a second telescopic portion from the other end of the water-cut portion weaved in the water-cut portion weaving step; a second rope weaving step of continuously weaving a ring-shaped braid of the second rope portion from a part of the other end of the second telescopic portion weaved in the second telescopic portion weaving step; and a water-cut portion disconnecting and closing step of disconnecting the aforementioned water-cut portion at one end and the other end and closing the disconnected portion.

[0041] Second embodiment: This embodiment is a method for manufacturing a water-cutting net piece by piece. The weaving process of the water-cutting part 10, the telescopic part 20 and the rope part 30 is substantially the same as that of the above embodiment, so it will not be illustrated here, but will be simply described.

[0042] First, in the water-cut portion knitting step, the water-cut portion 10 is knitted from one end to the other end into a tubular shape using only inelastic yarn.

[0043] Next, in the stretch portion knitting step, the supply of the elastic thread is started, and the stretch portion 20 is continuously knitted from the other end of the water-cut portion 10 using the inelastic thread and the elastic thread.

[0044] Next, in the rope braiding process, the supply of the inelastic thread is stopped, and the loop structure of the rope 30 is continuously braided from the other end of the stretchable portion 20 with the same elastic thread as the stretchable portion 20. In this way, a structure in which the water-cut portion 10, the stretchable portion 20, and the rope 30 are continuous in this order is formed.

[0045] Finally, one end of the water-cutting portion 10 is sealed by welding the two ends together with inelastic threads or curing them with an adhesive in the manner described in the above embodiment, thereby completing the water-cutting net 1.

[0046] In summary, the water cutting net manufactured in the above manner has a cylindrical water cutting portion 10 at the bottom, a telescopic portion 20 provided all around the opening end of the water cutting portion 10 , and a ring-shaped rope portion 30 provided at the opening end of the telescopic portion 20 .

[0047] The telescopic portion 20 covers the opening edge of the garbage receiver at the drain outlet, so that the water-cut portion can be inserted into the garbage receiver and can capture foreign matter flowing in during the drainage process and allow the drainage to pass through. When the rope portion is pulled up, the telescopic portion is separated from the opening edge of the garbage receiver and the water-cut portion can be removed from the garbage receiver while still containing foreign matter.

[0048] The manufacturing method includes: a water-cut portion weaving step of weaving a water-cut portion in a tubular shape from one end to the other end; a telescopic portion weaving step of continuously weaving the aforementioned telescopic portion from the other end of the water-cut portion weaved in the water-cut portion weaving step; a rope weaving step of continuously weaving a ring-shaped rope portion from a part of the other end of the telescopic portion weaved in the telescopic portion weaving step; and a water-cut portion closing step of closing one end of the water-cut portion.

[0049] The disposable water cutting net 1 manufactured by the above-mentioned manufacturing method in the present application includes a water cutting part 10 with a bottom cylinder, a telescopic part 20 arranged around the first opening end 11 of the water cutting part 10, and a ring-shaped rope part 30 arranged at the second opening end 21 of the telescopic part 20. The ring-shaped rope part 30 and the telescopic part 20 are woven together, and the telescopic part 20 and the water cutting part 10 are woven together.

[0050] In the water cutting network 1 of this configuration, as Figure 2 As shown, the telescopic portion 20 covers the opening edge F of the garbage receptacle G of the drain outlet, so that the water cut portion 10 is inserted into the garbage receptacle G. In this state, foreign matter such as kitchen waste that flows into the garbage receptacle G together with the drainage water is captured by the water cut portion 10, and the drainage water only passes through the water cut portion 10.

[0051] Continue to use the above method. When a certain amount of foreign matter accumulates in the water-cutting part 10, pull up the rope part 30, and the telescopic part 20 will be detached from the opening edge F of the garbage receiver G. At the same time, the first opening end 11 of the water-cutting part 10 is contracted by the telescopic part 20. This ensures that the foreign matter in the water-cutting part 10 will not accidentally overflow to the outside. In this state, it is easy to grab the rope part 30 and discard the water-cutting net 1 together with the foreign matter to a designated location. In this way, when discarding, there is no need to directly touch the water-cutting part 10 or its first opening end 11, but to grab the rope part 30 that is farther away from them, so it is more hygienic. After discarding, insert the new water-cutting net 1 into the garbage receiver G again according to the above method.

[0052] The water cutting part 10, the expansion part 20 and the rope part 30 of the water cutting net 1 are all woven from synthetic fibers.

[0053] The water-cutting part 10 is made of a braided fabric made of non-elastic threads such as polyester threads or nylon threads, for example, by a circular knitting machine. Here, as a synthetic resin thread, polyester threads are superior to nylon threads in terms of heat resistance and acid resistance. The mesh size of the water-cutting part 10 should be able to capture fine foreign matter while ensuring water permeability.

[0054] The telescopic portion 20 is woven at the first open end 11 of the water-cutting portion 10 by combining the inelastic thread with a more elastic elastic thread. The elastic thread can be a polyurethane thread, or a single-layer coated thread or a double-layer coated thread obtained by coating a high elastic core thread such as a polyurethane thread with a nylon thread or the like. Of course, any elastic thread can be used.

[0055] The cord portion 30 is connected to the first open end 11 of the telescopic portion 20 through a portion 40. Specifically, when the telescopic portion 20 is knitted, after the knitting of the telescopic portion 20 of a predetermined width is completed, the supply of the inelastic thread to the knitting machine is stopped, and the knitting action of the knitting machine is changed so that the telescopic portion 20 and the cord portion 30 are discontinuous at the portion 40, so that the cord portion 30 is knitted only with the elastic thread. Therefore, the cord portion 30 is knitted only with the elastic thread constituting the telescopic portion 20. The length of the portion 40 where the telescopic portion 20 and the cord portion 30 are continuous is set to about one fifth to one eighth of the circumference of the opening of the telescopic portion 20. If the length exceeds this range, when the water cut portion 10 is inserted into the garbage receptacle G of the drain outlet, the cord portion 30 may be entangled on the outer circumference of the garbage receptacle G, making it difficult to grasp.

[0056] As described above, the disposable water-cutting net 1 disclosed in the present application can be manufactured through a series of processes of a weaving machine from the water-cutting part 10, the telescopic part 20 to the rope part 30, thus eliminating the conventional additional process of the rope part 30. This makes it superior to the conventional process in productivity and can achieve extremely low cost.

[0057] Specifically, the disposable water-cutting net includes a water-cutting part with a bottom cylinder, a first opening end is provided on the water-cutting part, a telescopic part is provided around the entire circumference of the first opening end, a second opening end is provided on the telescopic part, and a ring-shaped rope part is provided at the second opening end. The telescopic part at the opening end of the water-cutting part covers the opening edge of the garbage receiver of the drainage outlet, so that the water-cutting part can be inserted into the garbage receiver, and the water-cutting part can be used to capture foreign matter flowing in during the drainage process, and the drainage can pass through the water-cutting part. At the same time, when the rope part is pulled up, the telescopic part at the opening end of the water-cutting part is separated from the opening edge of the garbage receiver, and the water-cutting net is removed from the garbage receiver when the water-cutting part still contains foreign matter. The water-cutting net is characterized in that the telescopic part is connected to the opening end of the water-cutting part, and the rope part is connected to the telescopic part of the opening end of the water-cutting part through a part, so that the water-cutting net can be used once.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
