DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape dispenser, and more particularly, to an adhesive tape dispenser which can cover a cutting blade when not in use and which can be easily carried as needed.

[0002]

2. Description of the Related Art Conventionally, a desk-mounted adhesive tape dispenser having a cutting blade capable of rotatably supporting an adhesive tape wound in a roll shape and cutting the adhesive tape into predetermined lengths. It has been known. The pressure-sensitive adhesive tape dispenser includes a main body that rotatably supports a roll-shaped pressure-sensitive adhesive tape, and is configured by disposing a cutting blade on a blade holder at a position separated by a predetermined distance from the rotation center of the pressure-sensitive adhesive tape. Here, in the known adhesive tape dispenser, the blade holder is rotatably connected to the main body, and a protective cover is provided on the tip side of the blade holder to protect when the adhesive tape is pulled down in a cutting direction. There is a configuration in which the cover is pushed down to expose the cutting blade (for example, see Japanese Utility Model Publication No. 7-18549).

[0003]

However, in the pressure-sensitive adhesive tape dispenser disclosed in Japanese Utility Model Publication No. Hei 7-18549, the protective cover is elastically deformed by the pulling-down force of the pressure-sensitive adhesive tape, and the protective cover is deformed downward. In this case, the lead force of the roll-shaped pressure-sensitive adhesive tape supported by the main body tends not to remain at the cut position due to the reaction force when the cut is performed. Further, in some cases, the lead end may be pulled into the roll side of the adhesive tape, and the inconvenience that the lead end cannot be found the next time the adhesive tape is pulled out may be caused. Such inconvenience is particularly apparent when the adhesive tape is a tape having relatively low adhesive strength, such as a mending tape or a drafting tape.

It is received in the formed guide grooves 42, 57, thereby
The main body 12 can be positioned at a predetermined position in the vertical direction with respect to the support member 15.

On the lower surface of the plate 105, an adhesive layer 111 made of urethane or the like is laminated.
1 adheres to the installation surface S, so that the support member 15
Can be fixedly installed. When the adhesive layer 111 according to the present embodiment is separated from the installation surface S, the adhesive layer 111 does not transfer to the installation surface S and always remains on the lower surface of the plate 105. Also,
The adhesive layer 111 can be washed and can be re-adhered, so that the initial adhesive strength can be continuously maintained.

The outer peripheral edge of the plate 105 is partially thinned to form a gap into which a coin or the like can be inserted with the adhesive layer 111 adhered to the installation surface S. And the adhesive layer 111
Consequently, when the plate 105 needs to be peeled off from the installation surface S, it can be easily peeled off. However, the pressure-sensitive adhesive layer 111 can be peeled off from the installation surface S by applying a force in a direction in which the entire support member 15 is inclined.

When the adhesive tape dispenser 10 is used as an installation type, the plate 105 on which the adhesive layer 111 is laminated is set on the lower surface side of the bottom wall 100 of the support member 15 and the adhesive layer 111 is placed on the surface S to be installed. To adhere.
Then, as shown in FIG. 19, the main body 12 is lowered from above to be supported by the support member 15.

Here, when the adhesive tape T is pulled out by a predetermined amount, the blade holder 13 may be rotated to open the opening 11 of the main body 12. At this time, at the position where the opening 11 is closed, the cutting blade 75 is covered by the distal end side of the plate-like member 14, but the plate-like member 14 is turned by the turning operation to the opening position, that is, the use position. Blade holder 1
The cutting blade 75 is relatively moved along the third curved piece 60 in the retreating direction to expose the distal end side of the cutting blade 75. Therefore, in this state, the adhesive tape T can be pulled out and cut. When the adhesive tape T is pulled out and cut, since the adhesive layer 111 is adhered to the installation surface S, there is no need to press the main body 12 with one hand, and the support member 15 is a plate. Since it is rotatable relative to 105, as shown in FIG. 20, it is possible to rotate 360 degrees, and the direction in which the hand accesses the lead end of the adhesive tape T is not restricted.

When the adhesive tape T is not used,
What is necessary is just to rotate the blade holder 13 to the closing position, and can carry it in this state. When carrying,
By lifting the main body 12 upward, the support member 1
5 can be easily separated.

[0030]

Therefore, according to the above construction of the present invention, the blade holder covers the cutting blade at the position where the opening of the main body is closed, and retreats from the tip of the cutting blade at the position where the opening is opened. Since the protection means is provided, the cover and exposure of the cutting blade can be performed only by opening and closing the opening. Moreover, when the cutting blade is exposed, it can be used in the same manner as a normal installation type adhesive tape dispenser, so that the lead end of the adhesive tape left on the main body side is adhered to the cutting blade area. To cut the adhesive tape. Therefore, it is possible to avoid the inconvenience that the lead end cannot be found the next time the adhesive tape is pulled out. Also,
The main body side can be carried with the opening closed by the blade holder, and the risk of inadvertent injury from the cutting blade during carrying can be prevented.

Further, since one end side of the plate-like member constituting the protection means is provided at a position different from the rotation fulcrum of the blade holder, the plate-like member is automatically moved relative only by rotating the blade holder. The structure can be simplified.

Further, since the guide mechanism for guiding the relative movement of the plate-like member is provided, when the blade holder is rotated, the protection means can always move along a fixed movement locus, The displacement operation between the position where the cutting blade is covered and the position where the cutting blade is exposed can be performed smoothly, and stable positioning can always be performed.

Further, since the main body can be supported by the support member, the main body can be installed at a specific place such as a desk top surface, while the support member can be separated and carried with the support member left on the desk. . Moreover, according to the configuration in which the adhesive layer is provided via the plate, the support member and the main body attached to the support member can be rotated, and the adhesive tape can be drawn out in all directions.
