Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a cleaning brush.

More specifically, it relates to a cleaning brush devised so that the bristles of the brush portion do not fall out.

<< Prior Art >> A brush for cleaning a glass container such as a beaker or a glass instrument conventionally used for cleaning a glass container such as a beaker in a laboratory has a structure as shown in FIG.

The structure of this container cleaning brush and the situation and function when used are described below.

First, the structure of a typical container cleaning brush is as follows.

That is, the bristles are inserted at a right angle in the winding part of the tip of the bare metal wire or the metal wire coated with a film such as vinyl chloride, which is substantially even in the length direction. It has a bristle part 3-1 and a grasping part 3-3 via a connecting part 3-2, which are distributed in a wrapped state.

The tip of the grasping portion 3-3 usually has a ring-shaped portion 3-4 for hooking it on a hook for storage.

Although there are individual differences in the specific operation method for cleaning a container or the like using this cleaning brush, the outline is as follows.

That is, it is common practice to hold the portion extending from the connecting portion 3-2 to the grasping portion 3-3 in the right hand and the outer periphery of the container to be washed in the left hand for the work.

More specifically, the brush for cleaning, etc., held in the right hand is rotated clockwise (clockwise) without being rotated, and the inner peripheral portion of the container is rubbed for cleaning.

However, the above-mentioned container cleaning brush has the following drawbacks.

<Problems to be solved by the invention> The problems are as follows.

That is, in a brush for cleaning containers, etc., which has a structure as shown in FIG. 2 which is currently on the market, a bare metal wire or two metal wires coated with a film such as vinyl chloride is used. The reason for the winding direction is unknown, but only the right-handed screw type (as shown in FIG. 3) is used.

If this right-handed screw type is not rotated, it is rotated clockwise (clockwise) to rub the inner circumference of the container, and the wound portion is inevitably caused by the frictional force between the brush part 3-1 and the inside of the container. Receive stress in the direction that the screw is unwound.

Normally, the brush part 3-1 is held only by being mechanically sandwiched in the winding part of the metal wire, and when the stress in the direction of unwinding the screw is applied as described above, the brush part inevitably consists of bristles. 3-1 falls off from the wound portion of the metal wire.

If a part of the bristles comes off from the wound part, it tends to come off one after another, and it becomes useless as a cleaning brush sooner or later.

In consideration of such a situation, as a result of earnest study by the present inventor,
The present invention has been completed.

<Construction of the Invention> That is, the present invention describes that "the ends of a plurality of wound metal wires or coated metal wires are substantially perpendicular to the metal wires, substantially even in the length direction, and bristles in all directions. In a cleaning brush having a brush part and a gripping part that are evenly distributed and arranged through a connecting part, a metal wire in which all or part of the connecting part that connects the brush part and the gripping part is not twisted or A cleaning brush characterized by comprising a coated metal wire "and" a plurality of twisted metal wires or coated metal wires at an end thereof substantially at right angles to the metal wire and substantially uniformly in the length direction. In addition, in a cleaning brush having a brush part in which bristles are uniformly distributed and arranged in all directions and a gripping part via a connecting part, the winding part has a left-handed screw type for cleaning. A brush.

The following is the first idea of the cleaning brush of the present invention (1)
Will be described in detail with reference to FIG. 1 showing one embodiment thereof.

Reference numeral 1-1 is a brush portion distributed with the bristles sandwiched at right angles, 1-2 is a connecting portion, and 1-3 is a non-twisted metal which is a feature of the cleaning brush of the present invention. Wire or coated metal wire portion. Also, 1-4 is a grasping unit,
1-5 is a ring-shaped part.

The brush part 1-1, the grasping part 1-4, and the ring-shaped part 1-5 need not be different from those of the conventional type.

Incidentally, the unwound metal wire portion 1-3 in the cleaning brush according to the first invention of the present invention has the effect of absorbing the stress in the unwinding direction in the winding portion as described above. is doing.

The length of the unwound metal wire portion 1-3 depends on the thickness of the metal wire used, that is, the size of the cleaning brush. For example, the thickness of the metal wire is 0.5 mmφ to 1 mmφ. In this case, it is preferable to set it to about 20 mm to 50 mm.

The reason is that the length of the unwound metal wire portion 1-3 is
This is because if it is less than 20 mm, the effect of absorbing stress cannot be exhibited.

Conversely, if the length of the metal wire portion 1-3 exceeds 50 mm, the effect of absorbing stress is sufficient, but the overall length becomes too long and the balance becomes poor.

The thickness of the wound metal wire does not have to be particularly different from that of the conventional type.

The same applies to the winding pitch of the wound metal wire.

The winding portion divided into two parts may be either a left-handed screw type or a right-handed screw type.
Also, a combination thereof may be used. In the cleaning brush according to the first device (1) above, even if the cleaning brush is rotated counterclockwise due to the stress absorption effect of the unwound metal wire portion,
On the contrary, even if the work is turned clockwise, the stress that unwinds the wound portion does not act.

However, on the other hand, in general, most Japanese are right-handed, and if we focus on the fact that the way of moving the hands when washing is common, as described above, it is slightly more complicated than conventional products. Even if the cleaning brush having such a structure is not manufactured, the above-mentioned drawbacks can be solved by adopting the following simple structure.

Second invention of the cleaning brush of the present invention (2)
Will be described with reference to FIG. 2 showing one embodiment thereof.

Specifically, this is to provide a simple structure in which the twisted portion of the metal wire is of a left-handed screw type.

Fig. 2 shows only the winding part of the metal wire, but the characteristic of this part is that it is a counterclockwise advancing screw in the opposite direction as compared with the conventional product which is formed in the clockwise advancing screw type. It is located in the mold.

All other parts are the same as the conventional products, and there is no problem.

<< Effect of the Invention >> The cleaning brush according to the present invention can be used for a long period of time without a part of the bristles falling off from the wound portion.
