At this time, the following main cutting part 13 has been cut beforehand, but the cut line 6 is not formed at the other end 13b of the main cutting part 13, thereby peeling off shifts to the next main cutting part 13 while making a new rip between the other end 13b and the following cutting part 14 by pulling and peeling off.

Description

  The present invention relates to a cleaning adhesive roll that can be effectively used for a cleaning tool for removing dust such as lint and hair entangled in a carpet or the like.

  Generally, cleaning tools for cleaning carpets use cleaning adhesive rolls in addition to vacuum cleaners. In the latter cleaning adhesive roll, the adhesive roll wound around the shaft core with the adhesive layer of the band-shaped adhesive tape on the front side is inserted into the shaft of the cleaning tool and rotated to rotate the adhesive roll. It is removed by adhering. When dust adheres and the adhesive strength of the adhesive tape on the surface layer decreases, the adhesive tape is cut out and an unused adhesive tape in the lower layer is newly exposed on the surface and used.

  In the cleaning adhesive roll, for example, as in Patent Document 1, in order to facilitate cutting, a slit made of a perforation is formed in the adhesive tape every round.

JP 2002-2224011 A

  However, in the cleaning adhesive roll according to Patent Document 1, it is cut along the perforation by peeling off the used adhesive tape, but the cutting direction is removed from the perforation, creating a tear, A part of the used adhesive tape may remain, or a new adhesive tape part may be broken and cut off excessively.

  If part of the used adhesive tape remains, it is necessary to cut the remaining part along the perforation again, and if the new adhesive tape part is also torn and cut, In addition to throwing away new parts, the next time the used adhesive tape is cut off, there is a nuisance to find and tear off the tear.

  An object of the present invention is to solve the above-mentioned problems and to provide a cleaning pressure-sensitive adhesive roll capable of reliably cutting off a used pressure-sensitive adhesive tape on a surface along a cut line.

  The cleaning pressure-sensitive adhesive roll according to the present invention for achieving the above object is formed by intermittently forming a cut along a linear direction to be wound around a shaft core with a pressure-sensitive adhesive layer of a band-shaped pressure-sensitive adhesive tape as a surface. In the adhesive roll for cleaning that cuts off the used adhesive tape by the cut and exposes the new adhesive tape in the lower layer, the cut has a number of main cutting parts and a secondary cutting part attached to the main cutting part. The main cutting part is arranged along the linear direction to be cut, and the sub-cutting part is slanted in the shape of a "<" from the one end part of the main cutting part to the twisted part side of the adhesive tape. The secondary cutting part is formed to extend short, and the secondary cutting part is located in an intermediate direction between the linear direction and the longitudinal direction of the adhesive tape with respect to the other end part of the adjacent main cutting part.

  According to the cleaning adhesive roll according to the present invention, the adhesive tape on the surface can be reliably cut off by the cut.

(A) is a schematic cross section along the longitudinal direction of the adhesive tape, (b) is a schematic cross section along the short direction. (A) is explanatory drawing of the cut of an adhesive tape, (b) is an enlarged view of a cut. It is explanatory drawing of the state which peels off the used adhesive tape. It is explanatory drawing of the cut of a modification. It is explanatory drawing of the cut of another modification.

The present invention will be described in detail based on the embodiments shown in the drawings.
As shown in FIG. 1, the cleaning pressure-sensitive adhesive roll 1 is configured by winding a belt-shaped pressure-sensitive adhesive tape 2 having a pressure-sensitive adhesive layer on the surface side around a shaft core 3 made of a paper tube. The adhesive tape 2 is provided with a cut 6 so as to make one turn on each circumference of the adhesive roll 1, and the length of the adhesive tape 2 is shortened as it goes to the lower layer. As shown in FIG. 2, this adhesive roll 1 is rotatably inserted into the shaft 5 of the cleaning tool 4 and used to cut off the dirty adhesive tape 2 by the cuts 6 provided for each predetermined length, thereby exposing the new Remove dust using a suitable adhesive layer.

  3A is a schematic cross-sectional view along the longitudinal direction of the adhesive tape 2, and FIG. 3B is a schematic cross-sectional view along the short direction. The base material 7 of the adhesive tape 2 is mainly composed of an upper layer sheet 8 made of paper and a lower layer sheet 9 made of synthetic resin. A rubber-based and resin-based adhesive layer 10 is applied to the surface of the upper layer sheet 8, and the lower layer sheet 9 A release layer 11 made of fluorine-based or silicon-based resin is applied to the back surface of the substrate.

  Further, the adhesive tape 2 is formed with a non-adhesive portion 12 having a predetermined width not provided with the adhesive layer 10 along the side edge portions on both sides thereof. The non-adhesive portion 12 is for picking with a finger when the adhesive tape 2 is cut off. Used as a hitting part.

  FIG. 4A is an explanatory diagram of the cut, and FIG. 4B is an enlarged view of the cut. In order to cut off the adhesive tape 2, a large number of cuts 6 are intermittently arranged at a slight interval along the linear direction A of the short side direction X which is the width direction. And the secondary cutting part 14. The main cutting portion 13 is formed along the short-side direction X, and the short secondary cutting portion 14 extends from one end portion 13a of the main cutting portion 13 toward the direction of about 45 degrees with respect to the linear direction A. "Is attached to the letter. The length of the secondary cutting portion 14 is adjusted so as to be positioned in the peeling direction B, which is an intermediate direction between the short side direction X and the long side direction Y, from the other end portion 13 b of the main cutting portion 13.

  The outer diameter of the adhesive roll 1 before use is 54 mm, the width of the adhesive tape 2 in the short direction is 160 mm, the width of the non-adhesive part 12 is 5 mm, and the adhesive tape 2 is wound about 90 turns around the shaft core 3. It has been turned. Moreover, the length of the main cutting part 13 is 5 mm, for example, and the length of the sub cutting part 14 is 3 mm.

  The cut 6 of the pressure-sensitive adhesive roll 1 obtained by winding the pressure-sensitive adhesive tape 2 around the shaft core 3 is formed by a shearing blade composed of a plurality of chips having a “<” shape. By pushing this shearing blade from the surface of the adhesive roll 1 toward the center of the shaft core 3, a large number of cuts 6 can be intermittently formed in all the layers of the adhesive tape 2 in one step.

  The reason why the large number of cuts 6 are intermittently formed in the short direction X is that the adhesive tape 2 needs to be continuous as one long tape. If the cut 6 is a straight cut with no uncut portion, the adhesive roll 1 will be divided by this cut, and the adhesive tape 2 will break apart from where it was cut during use. End up.

  When the carpet is cleaned while the cleaning adhesive roll 1 having the above-described configuration is attached to the cleaning tool 4 and rotated, dust adheres to the adhesive layer 10 of the adhesive tape 2. When the pressure-sensitive adhesive tape 2 in which a large amount of dust adheres and the pressure-sensitive adhesive force of the pressure-sensitive adhesive layer 10 is cut off, the unused portion of the pressure-sensitive adhesive tape 2 is newly exposed on the surface and can be used continuously.

  As shown in FIG. 5, the non-adhesive portion 12 on the curled side is picked with a finger and directed in the peeling direction B, and the used adhesive tape 2 is peeled off while being cut along the cut line 6. At this time, the main cutting portion 13 is cut in advance, but the cut 6 is not formed between the other end 13b of the main cutting portion 13 and the adjacent main cutting portion 13 and the secondary cutting portion 14. The next main cutting portion 13 is shifted to the next main cutting portion 13 while creating a new slit between the other end portion 13 b and the secondary cutting portion 14 by peeling.

  Since the peeling force with respect to the adhesive tape 2 is normally applied to the peeling direction B between the short side direction X and the longitudinal direction Y of the adhesive tape 2, a tear is generated in an oblique direction from the other end portion 13b of the main cutting portion 13. Then, since it reaches any point of the pre-positioned secondary cutting portion 14, it can reach the main cutting portion 13 via the secondary cutting portion 14 and the end portion 13a, and then shifts to the next main cutting portion 13 again. To do.

  In addition, it is also considered that the peeling force with respect to the adhesive tape 2 is applied only in the longitudinal direction Y of the adhesive tape 2, and in that case, the tear may be torn indefinitely in the longitudinal direction Y. Therefore, as shown in the modified example of FIG. 6, the tip of the secondary cutting portion 14 reaches the position in the longitudinal direction Y of the other end portion 13b of the main cutting portion 13 or higher, and the longitudinal direction Y of the main cutting portion 13 is increased. It is preferable that the tip of the other end portion 13b and the secondary cutting portion 14 coincide or overlap. By doing in this way, no matter which direction the peeling direction B is directed, the tear generated from the other end portion 13b almost certainly reaches the adjacent secondary cutting portion 14 and further cuts through the end portion 13a. It becomes possible to move to the section 13.

  As described above, in the present embodiment and the modification thereof, the adhesive tape 2 can be surely cut in the direction to be cut due to the presence of the secondary cutting portion 14 positioned between the main cutting portions 13 of the cut 6.

  Moreover, in the Example, although the direction of the cut line 6 was formed in the short direction X of the adhesive tape 2, as shown in the modified example of FIG. 7, the cut line 6 is an intermediate peeling direction between the short direction X and the longitudinal direction Y. You may form along the diagonal straight line A close | similar to B. FIG.
