Description

TECHNICAL FIELD The present invention relates to an auxiliary tool for cutting a used portion of a roll cleaner that collects dirt while rolling a roll of adhesive tape.

Roll cleaners are compact, do not require power, and can easily remove hair and lint, making them especially effective for cleaning small areas around you. However, as dirt accumulates on the roller surface, the adhesive tape loses its adhesion, so the used portion must be removed to expose the unused portion underneath. Used parts are usually removed by tearing them off by hand. Some roll cleaners come with a cut line, but if they don't have a cut line, you won't be able to cut it straight, and the ends of the unused part will often not line up neatly because you'll tear it off diagonally.

To solve this problem, for example, Japanese Utility Model Application Publication No. 4-114539 proposes an auxiliary tool for peeling off adhesive tapes. This auxiliary tool is a plate-shaped member with an adhesive surface, and as seen in the accompanying drawings of the same publication, it is a long and narrow plate like a ruler. The adhesive tape can be manually torn along the edge of the member to make a straight cut.

Utility Model Hei 4-114539

The peeling aid of Utility Model Publication No. 4-114539 is a long and thin plate that itself has an adhesive surface, so (although I have not seen the actual product), if you repeatedly adhere it to the adhesive surface of the roller surface, the whole thing will peel off quickly. I suspect that the adhesive will make it sticky. This not only makes it difficult to cut the used tape, but also makes the user's hands more likely to get dirty.
Furthermore, if the teeth of the auxiliary tool are applied perpendicularly to the roller surface, the force holding the roller will be weakened, making it difficult to cut, and it will be necessary to apply it to the adhesive surface to some extent.

An object of the present invention is to reduce the contact area between the cutting teeth and the adhesive surface of the roller surface, thereby eliminating the drawbacks of the prior art described above.

The adhesive tape cutting tool for a roll cleaner of the present invention that solves the above problems is an adhesive tape cutting tool for a roll cleaner, which has cutting teeth for cutting used adhesive tape and a grip part for a user to hold, The cutting tooth is characterized in that it consists of an inclined part that slopes upward from the cutting edge, and that the inclined part is provided with a recessed part to reduce the contact surface with the adhesive tape.

The recess preferably extends along the cutting teeth over almost the entire length in the longitudinal direction, and the deepest part thereof is preferably at least 0.5 mm, depending on the thickness of the adhesive tape cutting tool.

Preferably, a hook is provided at one longitudinal end of the cutting tooth to facilitate attachment to the adhesive tape of the roll cleaner.

Further, it is preferable that a corner of either the left or right end of the cutting tooth, on the side where the hook is not present, is made thinner by 1 to 3 mm than the tip of the other cutting tooth. This corner can be used to scoop up the leading edge of the used tape when peeling it off.

More preferably, the hook has a curved part inserted into a cylindrical part at the end of the adhesive roller. By using this curved portion, the adhesive tape cutting tool can be stably positioned relative to the adhesive roller.

The adhesive tape cutting tool of the present invention can be sold alone, or can be sold integrally as an accessory attached to a roll cleaner.

In the present invention, since the inclined portion constituting the cutting tooth is provided with a recess that reduces the contact surface with the adhesive tape, the contact surface with the adhesive tape can be reduced. Therefore, the used adhesive tape is easier to cut and the user's hands are less likely to get dirty.

(a) is a perspective view showing the state before attachment of the adhesive tape cutting tool, and (b) is a perspective view showing the state after attachment. (a) is a plan view of the adhesive tape cutting tool, (b) is a left side view, (c) is a front view, (d) is a right side view, (e) is a back view, and (f) is a bottom view. . FIG. 3C is an enlarged sectional view taken along the line IV-IV in FIG. 3(c).

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The adhesive tape cutting tool 2 of the roll cleaner 1 shown in FIGS. 1 to 4 is an embodiment of the present invention. The entire board is a thin synthetic resin board with a maximum longitudinal width of approximately 19 cm, a maximum height of approximately 4 cm, and a thickness of 2 to 3 mm. The material is not particularly limited.

The lower part of the adhesive tape cutting tool 2 is provided with longitudinally straight cutting teeth 22 that are applied to the adhesive tape 11 of the roll cleaner. The term adhesive tape 11 may include the used portion 11a. The cutting tooth 22 is an inclined portion provided on only one side extending approximately 10 mm upward from the leading edge 21 of the adhesive tape cutting tool 2. Although the "teeth" are intended to cut paper tape, they do not need to be sharp, and as shown in FIG. 4, the leading edge 21 is rounded to avoid danger.

However, the corner 28 of either the left or right end of the cutting teeth 22 (the side without the hook 26 described later) should be 1 to 3 mm thinner than the leading edge 21 of the other cutting teeth 22 by 5 to 30%. It is preferable. This corner 28 can be used to scoop up the leading end of the used tape 11a when peeling it off.

As shown in FIG. 4, a recess 23 extending in the longitudinal direction is formed from 3 mm to 8 mm upward from the leading edge 21 of the cutting tooth 22. As shown in FIG. This recess 23 is a space for reducing the adhesive surface.

Preferably, the recess 23 extends along substantially the entire length of the cutting tooth 22 in the longitudinal direction. Although the depth of the deepest part depends on the thickness of the adhesive tape cutting tool 2, it is preferably at least 0.5 mm.

Above the cutting teeth 22 is a grip portion 24 that is held and operated by a person. The top part consists of a horizontal part and gently sloping parts in front and behind it. As shown in FIG. 4, shallow cuts 25 are provided in the upper end contour from both sides. It is preferable that the shape and structure of the grip portion 24 be such that it is easy to grip by hand and has an excellent design.

A hook 26 is provided at one end of the cutting tooth 22 in the longitudinal direction to facilitate attachment to the adhesive tape of the roll cleaner 1. The curved portion 27 at the tip of the hook is inserted into the cylindrical portion of the roller core 12 (see FIG. 2).

As is clear from the above description, the method of using the adhesive tape cutting tool 2 of this roll cleaner 1 is as follows: After inserting the curved portion 27 of the hook tip of the adhesive tape cutting tool 2 into the roller core 12 and fixing the position, The cutting teeth 22 are brought into contact with the surface of the unused portion of the adhesive tape 11. Then, as shown in FIG. 2(b), the used adhesive tape 11a is manually torn off along the cutting teeth 22. Once the used adhesive tape 11a can be removed, the adhesive tape cutting tool 2 is separated from the roll cleaner 1 and is ready for the next use.

This adhesive tape cutting tool can be sold alone, or can be sold integrally with the main body of the roll cleaner as an accessory. When sold as a single unit, multiple types can be prepared to match the size of commercially available roll cleaners.
