Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to improvement of a roller for applying / absorbing liquid or for removing / cleaning a liquid.

<Prior Art> Conventionally, there has been an adhesive roller for cleaning as shown in FIG. 5, for example. This is one in which a roll (a) in which a cylindrical tubular body (f) having an adhesive portion (e) on the outer peripheral surface is fitted is fixed to a holding portion (b) that rotatably holds. The holding portion (b) is a shaft portion (c) that rotatably penetrates the roll (a), and a handle for pressing and rolling the adhesive portion (e) on the outer periphery of the roll (a) against the surface of another person. Equipped with.

The fact that the roll (a) and the tubular body (f) are separate bodies, i.e., that the adhesive part (e) is not directly provided on the roll (a), is the replacement of the worn adhesive part (e). This is to secure the sex.

Dust is removed by pressing such a roller against the surface to be cleaned and rolling it.

However, due to contraction of the roll (a) due to use in a cold place, or improvement of the adhesive strength of the adhesive part (e), the tubular body
It often happened that (f) fell off the roll (a).
More specifically, the cylindrical body (f) shifts in the (x) direction of FIG. 5 during use. In order to solve this point easily with a simple structure, a roll (a) having a shape shown in FIG. 6 has been proposed. In this method, a plurality of raised portions (g) having ridges (g ′) in a direction parallel to the shaft portion (c) are formed on the surface of the hollow roll (a) by blow molding. The ridges (g) extend parallel to the rotation axis of the roll (a) and are arranged at appropriate intervals (obviously, the ridges (g) are also parallel to each other). This ridge (g)
Each part of the ridgeline part (g ′) of is set to have the same height. In other words, it is configured to make line contact with the inner peripheral surface of the cylindrical body (f).

<Problems to be solved by the invention> However, although this is also easy to implement and easy to replace the tubular body (f), it is not a decisive point in securely holding the tubular body (f). There wasn't. That is, as shown in FIG. 7, the ridge line portion (g ') is caused by temperature change (especially in a roll formed by blow molding), slight deformation during molding, or how force is applied during use. Has a portion that does not come into contact with the inner peripheral surface of the tubular body (f) (portion other than the arrow in FIG. 7). In this way, in one ridge (g), the tubular body (f)
The fact that the ridge portion (g ′) has a portion that does not contact the inner peripheral surface itself does not directly affect the retention of the tubular body (f). However, if the contacting portion is at one point or concentrated at almost one place, the stability of holding the cylindrical body (f) is impaired, and wobbling and falling off are likely to occur. This causes a reduction in the retention rate, and even in the above-proposed roller, the problem of the tubular body falling off often occurs.

As a cause of the concentration of the contact portions, since the raised portions (g) are hollow and are formed in a series, it is possible that the deformation of one portion affects the other portions and causes a large retreat.

As described above, there is still no means for securely holding the tubular body (f) while ensuring the ease of implementation and the easy exchangeability of the tubular body (f).

The present invention aims to solve such a problem.

<Means for Solving the Problems> However, the present invention includes a tubular body, a core member that serves as a core of the tubular body, and a holding member that holds the core member so as to be rotatable in the circumferential direction. The core member includes a plurality of flexible small projections that are substantially evenly scattered on the outer peripheral surface of the core member. Roller characterized by having an absorbing member for liquid or the like on its peripheral surface The cylindrical body is a roller characterized by having an adhesive member for removing dust on its peripheral surface. An object of the present invention is to provide a roller characterized by comprising a tubular body holding portion and a handle connected to the holding member.

<Operation> In the present invention having the above-mentioned means, the small projections are uniformly scattered in each direction on the outer peripheral surface of the core member, so that one virtual straight line (the above-mentioned first (Corresponding to the ridge line part (g ') in Fig. 7), with appropriate intervals. It is possible to reliably obtain at least two contact points (with the inner surface of the tubular body). That is, since the small protrusions are independent of each other even in the direction parallel to the rotation axis, the deformation of one small protrusion does not affect the other small protrusion, and one small protrusion is in a state of not functioning. However, the other small protrusions along the above direction are replaced, and at least two point contact is made.

On the peripheral surface of the cylindrical body where liquid can be applied or removed, small projections are evenly scattered in each direction on the outer peripheral surface of the core member, so that a virtual straight line parallel to the rotation axis direction At (corresponding to the ridge line portion (g ') in FIG. 7), at least two contact points (between the inner peripheral surface of the tubular body and the core member) can be reliably obtained at appropriate intervals.

In a cylindrical body that has an adhesive member that can be rolled on the surface to be cleaned and can be cleaned, the small projections are evenly scattered in each direction on the outer peripheral surface of the core member, so that the rotation axis direction On one virtual straight line (corresponding to the ridge (g ′) in FIG. 7) parallel to the at least two contact points (between the inner peripheral surface of the cylindrical body and the core member) at appropriate intervals. Can be surely obtained.

In a cylindrical body that can be moved on the surface to be processed from positions that are appropriately spaced with handles, small protrusions are evenly scattered in each direction on the outer peripheral surface of the core member, so that parallel to the rotation axis direction. On one virtual straight line (the ridge line part in FIG. 7)
(corresponding to (g ')), it is possible to reliably obtain at least two contact points (between the inner peripheral surface of the tubular body and the core member) at appropriate intervals.

<Embodiment> A preferred embodiment of the present invention will be illustratively described in detail below with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this embodiment are not intended to limit the scope of the present invention to them unless otherwise specified. , It is just an example of explanation.

FIG. 1 shows an embodiment of the present invention. A hollow cylindrical body (1) having an adhesive member for removing dust or a water absorbing (moisture absorbing) member for applying liquid on its peripheral surface is attached to a separate roll (2) (cylindrical body (1 ) Is removable from the roll (2)). This roll
(2) is a columnar body whose axis (as a rotating body) is penetrated by a shaft (3). The roll (2) is loosely fitted around the shaft (3) so as to be rotatable. The roll (3) is preferably made by blow molding a plastic (which means a plastic material in a broad sense) into a hollow shape. Naturally, the small protrusions (5) described later are also integrally formed at this time. However, the present invention is not limited to the hollow molding, and at least the small projections (5) described later can be replaced by flexible ones as long as they have flexibility.

One end of the shaft (3) is extended to the outside, and the extension
A handle (4) is provided at the end (3 '). In detail, the shape of the shaft (3) includes the extension (3 '). It is a mold. this The horizontal part of the die tip penetrates the roll (2) as a rotation axis. The shaft (3) is not intended to be limited to the one bent into the mold.
Can be implemented with other shapes, and there is no problem even if it is straight without bending). A handle (4) is provided at the end of the vertical portion of the rear end.

A plurality of small protrusions (5) are provided on the outer peripheral surface of the roll (3). The small protrusions (5) are evenly distributed on the outer peripheral surface of the roll (2) at appropriate intervals. The distribution state may be random, but it is also effective if it has a certain consistency as described later. The shape of the small projection (5) may be a hemispherical shape shown in FIG. 2 (A), but as shown in FIG. 2 (B), it is a long sphere provided with a body portion (5 '). However, it can be implemented. Of course, the small protrusions (5) can be implemented even if they are ellipsoidal spheres. Furthermore, the small protrusion (5) may be a cone, or a polygonal pyramid as shown in FIG. 3 (A) (plan view) (here, it is a quadrangular pyramid, but even if it is a triangular pyramid, it has five or more pyramids. It may be a pyramid). Alternatively, it may be implemented in a radial shape as shown in FIG. 3 (B) (plan view) (here, it is a star shape, but other radial shapes can be used). In FIG. 3 (C), the third
The front view of a figure (B) is shown. Of course, even the one shown in FIG. 3 can be implemented as the one provided with the body portion (5 ') extended in FIG. 2 (B).

The arrangement of the small protrusions (5) will be described below. The small protrusions (5) may be located at random positions (positions that are inconsistent with other small protrusions) as long as they are evenly scattered, but it is also effective if they have consistency as described later. Roll (2) shown in Fig. 4 (A)
The small protrusions (5) are arranged on the virtual line (vertical line) (10) at appropriate intervals. Similarly, the small protrusions (5) may be arranged on the imaginary line (horizontal line) (10 ') at appropriate intervals, and further, the small protrusions (5) may be arranged at the intersections of the two imaginary lines (10), (10'). ) May be located. In addition, the imaginary line (1
1) Even if the small protrusions (5) are arranged on the
The small protrusions (5) may be arranged on the 1 '), or the small protrusions (5) may be arranged at the intersections of the virtual lines (11) and (11'). .

Further, the small protrusions (5) may be arranged on the phantom line (12) in FIG. 4 (C), or the small protrusions (5) may be arranged on the phantom line (13) in FIG. 4 (D). 5) may be arranged. Of course, it suffices that the uniform distribution be provided, and the arrangement of the small protrusions (5) is not limited to the above.

<Effect of the Invention> The tubular body can be securely held while ensuring easy exchangeability from the core member.

In the roller for liquid application, the easy application of the liquid application portion can be ensured, and the roller can be securely held. As a result, one roller can continuously and easily apply the liquid to the proper position on the work surface.

In the dust removing roller, the dust removing adhesive portion can be held easily while ensuring easy exchangeability. As a result, there is no need to be bothered with the displacement of the adhesive portion during cleaning using such a roller.

In various rollers that can be operated by holding handles from properly separated positions, the cylindrical body can be reliably held while ensuring easy exchangeability from the core member. That is, while the force point of the handle has an appropriate distance from the fulcrum of the core member (in this configuration, the conventional product is particularly apt to drop out of the tubular body), the work uncertainty due to the displacement of the tubular body Was eliminated. Of course, in this case as well, the ease of exchanging the tubular body is not impaired.
