The present invention relates to an adhesive cleaner including an adhesive tape roll which is formed by winding an adhesive tape with an adhesive surface thereof facing outward and which is rolled on a cleaning target surface thereby to collect dust adhering to the cleaning target surface on the adhesive surface, and more particularly to a small portable adhesive cleaner.
BACKGROUND ARTOne of cleaners removing dust adhering to clothes or the like includes a portable adhesive cleaner using an adhesive tape. For example, Patent Literature 1 discloses a portable adhesive cleaning tool including a cleaning tool main unit having a supporting shaft rotatably holding an adhesive tape roll wound so as to have an adhesive surface of an adhesive tape thereon facing outward; and a protective case attached to the cleaning tool main unit so as to cover an outer peripheral surface of the adhesive tape roll.
The adhesive cleaning tool includes a grip portion foldably connected to one end side of the supporting shaft. The grip portion is held by the hand when used. The grip portion serves as means of locking the protective case when folded. Accordingly, the adhesive cleaning tool can be used by expanding the grip in the folded state so as to be coaxial with the supporting shaft and then removing the protective case. The user can collect dust on the adhesive surface by rolling the surface of the adhesive tape roll on the clothes with the grip held in the hand.
However, the adhesive cleaner disclosed in Patent Literature 1 has encountered the following problems. Specifically, the grip is folded with respect to the supporting shaft, and thus the grip has a large outer diameter in the folded state. This increases the overall size of the cleaner, resulting that the cleaner is too bulky to carry around in a small bag, thereby causing inconvenience to the user.
In addition, the grip portion is folded and further serves as locking means, which means that the use needs to expand the grip before use, thereby preventing one-touch simple operation.

SUMMARY OF INVENTION Technical ProblemAccordingly, it is an object of the present invention to provide a portable adhesive cleaner having more portability, smaller in size, and easier to handle.
SOLUTION TO PROBLEMTo solve the above problems, the present invention has some features described below. Specifically, an adhesive cleaner according to the present invention includes: an adhesive tape roll having an adhesive tape with a dust collecting adhesive surface formed on one surface of a base material, the adhesive tape roll formed by winding the adhesive tape into a cylindrical shape with the adhesive surface facing outward; a cleaning tool main unit rotatably supporting the adhesive tape roll; and a protective case detachably attached to the cleaning tool main unit so as to cover the adhesive surface of the adhesive tape roll, wherein the cleaning tool main unit includes a supporting shaft rotatably supporting the adhesive tape roll and a grip portion disposed on one end of the supporting shaft, a stopper for retaining the adhesive tape roll is detachably attached to the other end of the supporting shaft, the protective case includes an opening portion at one end side, into which the adhesive tape roll supported on the supporting shaft is inserted, and a bottom lid at the other end on a bottom portion side, having a tapered barrel shape with an inner diameter thereof progressively increasing from the opening portion to the bottom portion, and a positioning means for positioning the supporting shaft coaxially with the protective case is disposed between the stopper and the bottom lid.
As a more preferred embodiment, the stopper is formed so as to have a larger diameter than at least a maximum outer diameter of the adhesive tape roll.
As a more preferred embodiment, the stopper is disk-shaped or polygonal.
As a more preferred embodiment, the positioning means includes: a hemispherical projecting portion formed on either one of the stopper and the bottom lid; and a hemispherical recessed portion formed on the other thereof, and the positioning means is centered such that when the projecting portion and the recessed portion are aligned with each other, an axial line of the supporting shaft is coaxial with an axial line of the protective case.
In addition, an inner peripheral surface of the protective case includes a plurality of ribs disposed along an axial direction of the adhesive tape roll.
ADVANTAGEOUS EFFECTS OF INVENTIONAccordingly, the cleaning tool main unit is formed in a stick shape with the supporting shaft and the grip disposed coaxially. The protective case can be inserted thereinto from a distal end of the supporting shaft, thereby providing a compact adhesive cleaner with good portability like a lip stick.
The cleaner further includes a projection and a recess as a positioning means disposed between the stopper and the bottom lid. The protective case and the supporting shaft can be easily centered simply by aligning the projection with the recess, which can prevent the adhesive tape roll from rattling inside the protective case when the cleaner is carried.
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited to this. As illustrated in
The adhesive tape roll R is formed by winding an adhesive tape, an adhesive surface of which is formed by applying an adhesive layer to one surface of a sheet-like base material, in multiple into a cylindrical shape so that the adhesive surface faces outward. In this example, the adhesive tape roll R is formed by winding a sheet having a width of 75 mm and a length of 1.5 m around a cylindrical body having an inner diameter of φ10 mm by 25 rotations (with a maximum outer diameter of 17 mm).
Note that the adhesive tape roll R according to the present invention may be substantially any cleaning adhesive tape roll with the adhesive surface facing outward, and the specific shape and specifications thereof may be arbitrarily selected.

The supporting shaft 21 exhibits a cylindrical shape insertable along an inner peripheral surface of the adhesive tape roll R. A stopper 4 for retaining the adhesive tape roll R is attached to a distal end thereof. An alignment portion 211 for guiding an insertion direction for attaching the stopper 4 is disposed on the distal end of the supporting shaft 21.
A hook claw 212 is disposed in a distal end of an inner peripheral surface of the supporting shaft 21. When the stopper 4 is attached to the supporting shaft 21, the hook claw 212 is engaged into a locking groove disposed on a side of the stopper 4. As illustrated in
With reference to
The locking shaft 42 is a cylindrical shaft erected vertically from the center of an upper surface (upper surface in
The locking groove 44 is formed into an L-shape including an introducing portion 44a extending vertically along an axial direction from an upper end of the locking shaft 42 and a locking portion 44b formed substantially horizontal along a circumferential direction of the locking shaft 42 from one end of the introducing portion 44a. The locking portion 44b is formed so that the opening width (length in an axial direction) is smaller on the inlet side and becomes larger toward the inside.
The locking shaft 42 of the stopper 4 is inserted into the supporting shaft 21 by pushing the hook claw 212 into the introducing portion 44a of the locking groove 44. Further, in this example, the locking shaft 42 is rotated clockwise about 90°, and then the stopper 42 is slightly pulled out in the axial direction. Thus, the hook claw 212 is entered and locked into the locking portion 44b, whereby the stopper 4 is attached to the distal end of the supporting shaft 21.
According to the present embodiment, the stopper 4 is formed in a disk-shape so as to have a larger diameter than a maximum outer diameter of the adhesive tape roll R, but in order to function to retain the adhesive tape roll R, the diameter of the stopper 4 may be larger than at least the inner diameter of the inner peripheral surface of the adhesive tape roll R. In addition, the shape of the stopper 4 is not limited to a disk-shape, but may be a polygon such as a square or a hexagon.
Further, the stopper 4 may be a so-called claw-shaped, and the recessed portion 43 for alignment may be formed in the bottom portion of the stopper 4. Furthermore, the recessed portion 43 may be a hole.
Referring back to
The lower end side (lower end in
The locking surface 23 is formed to be gradually reduced in outer diameter from the upper end side (side engaging with the grip portion 22) to the lower end side (side engaging with the supporting shaft 21) and the outer diameter on the upper end side is slightly smaller than the opening diameter of the protective case 3.
The outer peripheral surface of the locking surface 23 includes a locking projecting portion 231 engaged into a recessed groove 35 disposed on a side of the protective case 3. In this example, the locking projecting portion 231 includes projecting ribs protruding outside from the outer peripheral surface of the locking surface. In this example, three ribs are provided at intervals of 120°.
The number of the locking projecting portions 231 and the shape thereof may be arbitrarily changed in accordance with the specifications. In addition, the locking projecting portion 231 may be replaced with an annular rib, and the rib may have any shape allowing the rib to be entered and engaged into the recessed groove 35.
With reference to
An inner peripheral surface 32 of the protective case 3 is formed with the inner diameter thereof progressively increasing from the upper end to the lower end in the same manner as the outer diameter. In this example, an insertion surface 34 receiving the above described locking surface 23 is formed for a predetermined length from the opening portion 31 of the protective case 3.
The axial length of the insertion surface 34 is substantially the same axial length of the locking surface 23, and the inner diameter of the insertion surface 34 is substantially the same outer diameter of the locking surface 23. The insertion surface 34 includes a recessed groove 35 engaged with the above described locking projecting portion 231. In this example, the recessed groove 35 is made of an annular groove one step recessed along the inner diameter of the insertion surface 34. Note that the position and the shape of the recessed groove 35 may be arbitrarily selected according to specifications.
The inner peripheral surface 32 includes ribs 33 to prevent the adhesive surface from sticking to the inner peripheral surface 32 when the adhesive tape roll R is inserted in a state of being skewed relative to the axial line.
The ribs 33 are formed along the axial direction from the lower end of the insertion surface 34 on the inner peripheral surface of the protective case 3 to the bottom portion. In this example, 12 ribs are provided radially at a predetermined interval. The shape and the number of ribs 33 may be arbitrarily selected.

Then, the stopper 4 is attached to the distal end of the supporting shaft 21. Thus, the adhesive tape roll R is rotatably held by the supporting shaft 21. For using the cleaning tool main unit 2, a protective seal provided on the outer periphery of the adhesive tape roll R is peeled off and then the adhesive surface (not shown) exposed on the surface is rolled on clothes or the like, thereby allowing dust adhering to the clothes to be collected on the adhesive surface.
After use, as illustrated in
Even if the cleaning tool main unit 2 is skewed when the cleaning tool main unit 2 is inserted until it reaches the end, the present invention can allow the rib 33 to contact the outer periphery of the stopper 4, preventing the adhesive surface from contacting the periphery of the opening portion 31 and thereby preventing the adhesive surface from being contaminated or peeled off.
When the cleaning tool main unit 2 is further deeply inserted into the protective case 3 to the bottom, the recessed portion 43 of the stopper 4 is guided to the projecting portion 361 provided on the bottom lid 36 of the protective case 3, and at the same time the insertion surface 23 of the cleaning tool main unit 2 is locked with the locking surface 34 of the protective case 3.
Thus, the supporting shaft 21 is supported by two points: one at the distal end side (side of the stopper 4) and one at the proximal end side (side of the grip portion 22). The adhesive tape roll R is held coaxially along the central axis of the protective case 3, which can securely prevent the adhesive surface from sticking to the inner peripheral surface of the protective case 3. Particularly when the cleaning tool main unit 2 is portably carried, the adhesive tape roll R can be prevented from rattling in the protective case 3.
In this example, the outer shape of the protective case 3 is conically formed to fit the inner diameter so as to be stable when the protective case 3 is set at a stationary state, but the protective case 3 may be formed simply with cylindrical inner peripheral surface and outer peripheral surface, or at least the inner peripheral surface that can store the adhesive tape roll R, and the outer shape may be quadrangle or the like.
