JPS63300001A - Filter for sink tank - Google Patents

Abstract

PURPOSE:To make it easy to attach a filter for a household sink tank, by forming the filter bag of a synthetic fiber non woven fabric, in an integrated one body, and extending this filter bag as the mesh becomes loser from a flange set at the brim of the filter bag toward the bottom. CONSTITUTION:A filter bag 1 is formed of a polyester non drawn synthetic fiber non woven fabric, in an integrated one body, and this filter bag 1 is attached from the center part of a flat ring-shaped flange 2, as extending the side 5 and the bottom 6 in one body. In this case, the filter bag 1 is extended as meshes of the brim 4 near the flange 2 become close, and meshes of the side 5 and the bottom 6 become looser. With this constitution, the filter can be attached easily, through only holding the flange 2 for putting the filter bag 1 onto a basket-shaped filter case.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a filter used in a sink installed in a home kitchen or the like.

[Prior art] Wood chips, tea leaves, etc. from cooking usually flow into the drains of sinks installed in home kitchens, so there is a risk that the drain pipes etc. will be clogged by these debris. There is.

Therefore, in order to prevent cooking waste from flowing into the sink drain, sinks are often used in which a basket-like mesh filter made of metal, synthetic resin, etc. is attached to the drain.

However, filters with such meshes quickly become clogged with dirt, which is not easy to remove, so it is often difficult to ensure drainage while maintaining the filtration effect at all times.

Therefore, in order to make it easier to remove dust from the filter, a perforated bag made of synthetic resin, a bag made of Japanese paper, or the like is installed inside the above-mentioned cage-shaped filter.

[Problems to be solved by the invention] Conventional bags attached to the inside of cage-shaped filters are simple three-sided sealed bags with an opening at the top, or triangular bags. It is often difficult to easily and properly attach the filter to the filter.

It is an object of the present invention to provide a sink filter that can be easily installed and eliminates the problems encountered during installation.

[Means for Solving the Problems 1] The present invention is a bag integrally molded from a synthetic fiber nonwoven fabric, the bag having an outward flange at its upper end, and a side flange on the side of the bag. The bottom part and the bottom part are a sink filter characterized by a fiber structure that is more coarsely stretched than the flange part.

The synthetic fiber nonwoven fabric referred to in this invention needs to be able to be stretched to large deformations. For example, it is preferably a nonwoven fabric of undrawn fibers or semi-drawn fibers made of polyester polymer, etc., which can be molded into a large deformation in a hot atmosphere of at least 11 JO.

Synthetic fiber nonwoven fabrics that are integrally molded using methods such as hot press molding have a considerable degree of shape retention in the relationship between the flange and the upper side of the bag. It can be easily installed by simply placing it on top of a basket-shaped filter or placing it on a drain port and pressing it with a rubber stopper that has an opening. In addition, since the fiber structure of the nonwoven fabric is coarse in the sides and bottom of the bag, it is possible to sufficiently ensure garbage separation and water permeability.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a front view of a bag body 1 integrally molded from polyester-based unstretched synthetic fiber nonwoven fabric, in which side parts 5 and bottom part 6 are integrally stretched from the center of a flat ring-shaped flange part 2. As shown in FIG. 2, the flange member 2 is provided with a gripping portion 3 for easy gripping.

The side parts 5 and the bottom part 6 are provided by being stretched,
The mesh is narrow in the vicinity of the upper edge 4 adjacent to the flange 2, and gradually becomes coarser from the side 5 to the bottom 6.

In this filter, the bag 1 can be easily installed inside the cage-like filter by simply grasping the flange member 2 and placing it on the cage-like filter. In addition, if a basket-shaped filter is not attached to the drain of the sink, grasp the flange member 2, place it on top of the drain, and press the flange member 2 around the drain with a rubber plug with an opening. , this filter can be attached to the drain.

The side parts 5 and bottom part 6 of the bag body 1 are stretched and have a coarser fiber structure than the flange part, so that sufficient water permeability can be ensured, and the mesh is finer than that of the cage-shaped filter. This prevents dust from flowing out of the sink and keeps the drain pipe and basket-shaped filter clean.

[Effects of the Invention] The bag body of the present invention is integrally made of synthetic fiber nonwoven fabric, so it has good shape retention, and the opening edge has a flange with high fiber density and good shape retention, so It has the effect of being extremely simple and easy to install inside a filter or drain port. Since the sides and bottom of the bag are stretched and made coarse, it is possible to prevent dust from flowing out while ensuring water permeability.
