Description

[Detailed description of the invention] Industrial field of application The present application is provided with a winding frame of an adhesive tape rotatably mounted thereon and a cutting blade for cutting the adhesive tape pulled out from the frame into a desired length. This relates to a tape cutter that is placed on a tabletop or the like.

Conventional technology and problems Conventionally, an adhesive tape reel is rotatably mounted, and the adhesive tape pulled out from the reel is rotatably mounted.
A tape cutter that is used by placing it on a tabletop or the like is equipped with a cutting blade that cuts the tape to a desired length.The tape cutter is equipped with a support part at the rear that removably supports a reel that fits and supports an adhesive tape reel. It also has a columnar shape with a cutter part extending vertically in the front part and having a cutting blade and an attachment part to which the end face of the adhesive tape is attached after cutting, in order to facilitate next use, on the top surface. The cutter is made of polypropylene, and a protective member is attached to the holding part to protect the cutting blade and maintain the adhesion of the adhesive tape. It is made by filling an outer casing with concrete or other material to give it weight.

By the way, the protection member in a conventional tape cutter has a pair of left and right support pieces at the upper end portions of which the lower ends are rotatably attached to the side surface of the cutter portion via a protruding shaft.
When it rotates vertically, a covering piece is provided so as to cover the cutting blade and the attachment part, so that the covering piece can be
The adhesive tape cannot be pressed against the top surface of the adhesion part, so the adhesive tape easily comes off from the adhesion part due to the action of external force, which has the disadvantage of hindering the next use and also getting in the way during use. There was a defect.

Purpose, Examples, and Effects of the Invention Therefore, the present invention improves the defects of the conventional one by making it possible to press the covering piece on the upper surface of the attachment part. The support part 3 has a recessed part 2 with an open top surface at the rear, extends vertically to the front part, and integrally has a sawtooth cutting blade 4 and a horizontal attachment part 5 on the top surface. The main body is made by filling a heavy object such as concrete into an outer casing made by integrally molding a columnar holding part 7 with a metal cutter part 6 attached thereto from a synthetic resin such as polypropylene.
The support part 3 is provided with engagement grooves 9 on the left and right sides of the recessed part 2 to support the shaft 8' of the reel 8 to which the reel A of the adhesive tape a is removably fitted. The holding portion 7 is provided with a pair of left and right ribs 10, 10 that continuously extend at a constant interval t from the outer vertical surface to the top surface thereof.
A first hinge portion 11 is located above the outer vertical surface of the
A plate-shaped connecting piece 12 is connected to this connecting piece 1 via
A plate-shaped cover piece 14 extending via a second hinge part 13 is integrally provided at the tip of each of the two pieces. The connecting piece 12 has a wide width so that one half of the connecting piece 12 is closely engaged between the pair of ribs 10, and the entire length extends from the first hinge part 11 to the cutter part 6.
The cover piece 14 has a length that reaches the height of the attachment part 5 of the pair of ribs 1, and the tip of the cover piece 14
It is formed wide enough to tightly engage between the cutting blade 4 and the attachment part 5, and has a length that is necessary to cover almost the entire surface of the attachment part 5 from the cutting blade 4. 15 is a gripping tongue piece.

Therefore, in the usage state where the adhesive tape a is cut, the connecting piece 12 is inserted through the first hinge part 11.
and the cover piece 14 are hung down, and their respective wide parts are tightly engaged between the vertical parts of the pair of ribs 10, 10, respectively, and in this state, the cover piece 14 is pulled out from the reel A as in the conventional case. The adhesive tape a is cut by the cutting blade 4, and the end face of the cut adhesive tape a is attached to the attachment part 5.

After using the adhesive tape a in this way, hold the tongue piece 15, remove the cover piece 14 and the connecting piece 12 from between the pair of ribs 10, 10 in sequence, and remove them in the direction of the arrow. At the same time, the wide part of the connecting piece 12 is connected to the pair of ribs 10, 10.
Then, by bending the cover piece 14 from the second hinge part 13 and engaging its wide part between the horizontal parts of the pair of ribs 10, 10, the adhesive is removed. The tape a is pressed against the attachment portion 5 from its upper surface.

In addition, in the above, the connecting piece 2 is connected to the outer casing,
Although the case where they are provided integrally via the first hinge part 11 is illustrated, it is also possible to configure these separately and attach the connecting piece 2 to the ribs 10, 10 so as to be rotatable by known means. , and that only the cover piece 14 may be engaged between the pair of ribs 10, 10;
Furthermore, it goes without saying that other engaging portions may be provided in place of the pair of ribs 10, 10.

Effects of the invention As described above, according to the present application, since the adhesive tape can be pressed against the adhesive part from above by the cover piece, the adhesion state of the adhesive tape can be maintained reliably, making it convenient for next use. It has the advantage of
