Abstract
Description
Technical Field
[0001] The present invention relates to a laundry net bag used during washing, and more particularly to a laundry net bag having a structure for preventing the snagging of a fastener and the entanglement of the net.
Background Art
[0002] In the prior art, various clothing items such as medical gowns used in medical facilities and other places, bedding items such as sheets, etc. are repeatedly used by being selected. However, after use, these are often contaminated by sweat, excretions, body fluids, etc. from the user, and from the perspective of infection prevention, etc., they need to be separated from general items and processed. Therefore, these items to be washed are, for example, washed at a specialized laundry factory, cleaning facility, etc. When performing processes such as collection, transportation, washing, and dehydration, after collecting and transporting them in a collection bag, they are transferred and stored in a laundry net bag of a predetermined capacity for washing and dehydration, and then put into a washing machine for processing.
[0003] However, when transferring from the collection bag to the laundry net, there is not only a significant risk of infection when handling the contaminated items to be washed, but also when stirring and washing in the washing water and further centrifugally dehydrating, it is necessary to store them with a margin inside the laundry net bag. For these reasons, although it is also done to use the laundry net bag as it is for collecting the items to be washed, if it is stored with a margin, only a small amount of the items to be washed can be stored compared to its capacity, so the laundry net bag becomes bulky and handling is troublesome.
[0004] In contrast, in Patent Document 1, a foldable net is provided inside the laundry net bag to make the entire laundry net bag stretchable and contractible, enabling a margin to be provided for the capacity of the items to be washed.
[0005] Furthermore, in Patent Document 2, a bag that is folded in half and stitched together with a joining fastener expands the storage space capacity of the bag, making it possible for the items to be washed inside the bag not to solidify during agitation washing and dehydration.

Summary of the Invention
Problems to be Solved by the Invention
[0007] However, although these technologies have achieved a sufficient capacity for the objects to be washed in the laundry net bag, since the objects to be washed are agitated in the washing water during washing and cleaning, and centrifugally processed during dehydration, there are problems such as the fastener at the opening / closing part of the laundry net bag opening and the internal objects to be washed leaking out, the slider of the fastener getting caught on the objects to be washed or the internal net and damaging the fabric, and the fastener sometimes biting the internal net when opening / closing the fastener, resulting in a decrease in work efficiency.
[0008] In addition, the objects to be washed are supposed to be washed at a specialized laundry factory, cleaning facility, etc. When performing processes such as collection, transportation, washing, and dehydration, they are collected and transported in a collection bag and then washed, dehydrated, etc. At this time, if the capacity of the laundry net bag used for the collection bag is too large to have a margin in terms of washing efficiency, there is a problem that the work efficiency of collection and other operations decreases.
[0009] The present invention has been made in view of such circumstances, and aims to provide a laundry net bag that prevents the handle of the fastener of the laundry net bag from getting caught, prevents the fastener from biting the internal net, prevents the objects to be washed from leaking out of the net, not only improves the work efficiency of the washing operation, but also improves the work efficiency including operations such as collection.
Means for Solving the Problems
[0010] In order to achieve the above object, the device according to claim 1 for a laundry net bag is configured such that the laundry net bag is cylindrical, openings are provided at the edges of the upper surface and the bottom surface of the laundry net bag, fasteners are provided at the respective openings, and a foldable net bag fixed to the edge of the bottom opening via a fastener is provided inside the laundry net bag.
[0011] And, the structure is such that the pull of the fastener is fixed to a slider, and further, the slider of the fastener is provided with a storage portion for storing when the fastener is closed, so that the slider of the fastener does not come off during washing.
[0012] Furthermore, a fastener tape is provided between the fastener at the edge of the bottom opening and the foldable net, so that the internal net is not caught when the fastener is opened and closed. (Claim 1)
[0013] Also, according to the present invention, by configuring the volume of the laundry net bag when the internal net is expanded not to exceed twice that of the laundry net bag, the handling property such as loading is improved and the working efficiency of loading etc. can be enhanced. (Claim 2)
Effects of the Invention
[0014] According to the laundry net bag of the present invention, since the fastener of the laundry net bag is fixed to the slider, the object to be washed is not damaged, and since the storage portion for the fastener slider is provided, the fastener does not easily open, so that the object to be washed does not leak out. Further, since the size of the internal net can be adjusted to be compact and the fastener tape is provided to reduce the catching of the internal net, the handling efficiency of the washing operation including loading etc. is improved.
