A regular adhesive tape in a straight line adheres firmly to the object to be adhered from end to end. Next, when one end of the straight adhesive tape is folded back and bonded to the object to be bonded, the other end is firmly bonded, but this one end has no adhesive surface at the bonded part Therefore, it is in a state where it is turned up and peeled off from the beginning. Therefore, the folded end can be easily peeled off with a fingertip. In this way, if you have a shape that combines the advantages of both, the adhesive tape has a part that can be firmly glued from end to end and can be peeled off without accidental peeling, just like a normal adhesive tape. Maintain a tight and tight seal. In this way, we will try to solve the inconvenience by making an adhesive tape cutter that has both features.

In order to eliminate the inconvenience described above, the present invention adds a gripping portion in which the palms of both hands are combined while maintaining the feature of hermetically sealing and sealing the straight adhesive tape from end to end. The end of this adhesive tape has a convex shape and forms a raised palm portion that faces upward. To provide an adhesive tape cutter that contributes to daily life by removing the weakness by making the convex type visible and touching with your hand and peeling it up with your fingertips, making the adhesive tape more convenient and easy to use Objective.

The pressure-sensitive adhesive tape cutter of the present invention shares a shaft with a pulley base rotatably provided with a pulley loaded with the pressure-sensitive adhesive tape, a former post spaced apart from the pulley stand, a latter post spaced apart from the former post, and the former post. The latter column is made up of a main column that supports the shaft by bifurcating via a spring, and serrated teeth.The pulley table, the former column, the latter column, and the serrated teeth are arranged in this order, and the pulley table and the The upper surface of the former support column has a larger bonding area and uneven teeth, and the upper surface of the latter support column has a smaller bonding area and has uneven teeth at positions facing the uneven teeth. By opening and closing the support post and the latter support post, the concave and convex teeth and the concave and convex teeth are meshed with each other, the combined surface of the concave and convex teeth and the convex and concave teeth is a flat surface, and the upper support post and the latter support post sharing the shaft The upper surface is the bar Spaced at the rebound along the circumferential line, characterized by comprising stationary mutually facing obliquely upward.

  Further, the present invention is characterized in that a handle for operating the opening / closing movement is provided on the latter column so that the latter column can be moved in the direction of the former column.

  Further, the present invention is characterized in that a handle for operating the opening / closing movement is provided on the former support column so that the former support column is movable in the direction of the latter support column.

Further, a fine groove is provided on the upper surface of the latter support column and a jagged tooth is provided on the side opposite to the former support column on the side of the fine groove so that the adhesive tape can be easily peeled off when forming the raised palm portion. Features.

Furthermore, a folding base with a narrow groove formed on the upper surface of the former support column and a detention table are provided in order from the pulley stand side, and a fine groove is provided on the upper surface of the latter support column to make it easy to form a raised palm portion. And

Further, the pulley stand and the base are provided as a circular cover, and the cover is used as a pulley base that holds the inner surface of the adhesive tape on the inner side and the base on the outer circumference, and the former support post on the lower surface of the concave and convex teeth The connecting surface is extended in the direction of the latter column and used as an end detention stand, and is a portable adhesive tape cutter that grips this cover with a fingertip.

  When the pressure-sensitive adhesive tape cutter of the present invention is loaded with pressure-sensitive adhesive tape, and the handle is operated and pushed by hand, the latter support column approaches the former support column sharing the axis, and the tip of the latter convex tooth and the fine groove with a minute inclined surface are attached. The teeth and teeth on the upper surfaces of the two pillars other than are combined into a single plane. When the hand is released from the handle, the teeth return to their original positions due to the repulsion of the spring and face up diagonally and rest. By this operation, the end of the adhesive tape remains in the form of a raised palm at the corner of the tooth on the upper surface of the former support column. When this shape is held and the adhesive tape is pulled out by hand to the required length and attached to the object, this shape creates a protrusion at the end of the adhesive tape that is in a straight line. Since there is a final cut end of the adhesive tape, the protruding portion sandwiched between the ends becomes a convex shape standing upward. And since the adhesive surface of this adhesive tape is from the beginning to the last end, it adheres firmly and will not be turned off due to an accident. Nevertheless, the convex end is immediately visible, touching the hand and picking it up with your fingertips. Also, for safety, there is no contact with the fingertips such as the cutter blade, the operation of the instrument is easy to use regardless of age and skill is not required, this adhesive tape sticks from one end to the final convex piece Because of the surface, the sealing and sealing work can always be performed accurately, eliminating the weaknesses of conventional methods and demonstrating the advantages of adhesive tape.

The narrow groove 25 may be roughened with a large number of minute protrusions 31.

  As shown in the enlarged views of FIGS. 3 and 4, the upper surface 12 of the latter support column is provided with a planar uneven tooth 13 so that the uneven surface 11 of the former support column 4 faces opposite to the uneven surface 11. . A fine groove 26 in the vertical and horizontal directions is formed on the surface of the planar convex / concave tooth 13, and a minute inclined surface is formed on the upper surface of the distal end portion 24 of the latter convex tooth 14 of the planar convex / concave tooth 13. The latter column upper side surface 21 shown in the enlarged view of FIG. 6 is formed. Further, a groove 15 that is ground in the lateral direction, that is, the direction in which the uneven teeth 13 are arranged in a plane, is formed on the base of the uneven teeth 13 in the plane, that is, on the side opposite to the distal end portion 24 of the latter teeth. Teeth 16 are provided. The fine groove 26 may be roughened with a large number of fine protrusions 31. 9 and 10 show the plate-like square teeth 28 and the plate-type square teeth 28 with the uneven teeth 11 made flat and the uneven teeth 13 made flat. Similarly, fine grooves 26 for roughening the surface are also provided on the upper surface 12 of the latter support column shown in FIG. FIG. 11 shows the shape of a side-to-side view in which the plate-shaped square teeth 28 and the plate-shaped square teeth 28 on both the columns are vertically superposed.

Moreover, the structure of the portable adhesive tape cutter shown to FIG. 15 and FIG. 16 is shown with the same code | symbol as the code | symbol shown to FIG. Next, the difference in shape from the adhesive tape cutter is that a cover 32 for loading the adhesive tape 19 is provided using the base 1 and the pulley base 18 together, and the inner surface of the adhesive tape 19 is held inside and rotated. A main pillar 3 is provided on the circumference of the pulley base 18 and the outer side of the cover 32 as a base 1, and the former support pillar 4 is extended laterally on the lower surface of the concave and convex teeth 11 on the upper face 8 of the former support pillar. The structure is the same as the structure of the adhesive tape cutter except that it is also used as an end-holding table 30, and the position of the handle 27 and the spring 7 is moved so that the pulley table 18 is gripped by the fingertip A. To do. The spring 7 used in the present invention is a spring 7 such as a torsion spring, a compression coil spring, a tension coil spring, or a leaf spring, and the position where the spring 7 is attached is the most effective place.

  Next, the usage state and process of the adhesive tape cutter of the present invention will be described with reference to FIGS.

1 to 8 show an embodiment of the present invention. The end of the adhesive tape 19 is pulled out from the pulley 2 in which the adhesive tape 19 is loaded on the pulley base 18 on the base 1, and the spring 7 acting on the former strut 4 and the latter strut 6 that are linearly mounted from the pulley 2 is mounted. An adhesive tape 19 that passes through the upper surface 8 of the former column and the upper surface 12 of the latter column and is cut by the serrated teeth 16 is prepared (see FIGS. 7A and 8I). Next, when the handle 27 is operated to move the latter support column 6 along the circumference to the former support column 4 and the former support column 4 and the latter support column 6 sharing the shaft 5 are opened and closed, The adhesive tape 19 straddling the upper surface of the support column is curved upward (see FIGS. 7B and 8B). Next, the tip of the latter convex tooth 14 having a minute inclined surface on the tooth tip of the convex tooth 13 on the upper surface 12 of the latter post is located on the concave tooth 11 on the upper surface 8 of the former post. When the concave and convex teeth 11 and the concave and convex teeth 13 come together under the adhesive tape 19, the flat cut end 22 </ b> A of the adhesive tape 19 on the upper surface 12 of the latter column is laterally displaced from the upper surface 12 of the latter column and is easily lifted off. It becomes. Therefore, the top surface 8 of the former support column is provided with the uneven teeth 11 and the top surface 12 of the latter support column is provided with the uneven teeth 13 at the position facing the uneven surface 11, thereby accurately forming the raised and raised palm portions 22. The upper inner surface of the protruding portion 23 is bonded to the palm while leaving an unbonded space (see FIGS. 7C and 8C). When the hand 27 is released from the handle 27, the concave and convex teeth 11 and the concave and convex teeth 13 which are combined to form the combined surface 17 are separated by the repulsive force of the spring 7, and when the latter support column 6 returns to the original state, the adhesive tape 19 is flat. The cut end 22 </ b> A is separated from the upper surface 12 of the latter support column and remains at the end of the raised palm portion 22 at the corner of the retaining table 10 and the uneven teeth 11 on the upper surface 8 of the former support column. Then, the upper surface 12 of the latter column is separated along the circumferential line about the shaft 5 and faces obliquely upward and stops (see FIGS. 7D and 8D). The action of the adhesive tape 19, the concave and convex teeth 11 and the concave and convex teeth 13 are engaged with each other so that the end of the latter convex tooth 14 on the concave and convex teeth 13 enters the concave and convex teeth 11 and moves to the end. When the uneven teeth 13 with the fine grooves 26 are separated from the uneven teeth 11, peeling is promoted by the action of the fine grooves 26. The adhesive tape cutter that performs these two peeling operations is always stable even when used continuously for a long time regardless of the strength or type of the adhesive force of the tape, and the protruding palm 22 is formed at the end. The instrument may be fixed to the table for packing.

The first condition for forming the protruding palm portion 22 at the end of the adhesive tape 19 of the present invention is a pulley base 18 on which a pulley 2 loaded with the adhesive tape 19 is rotatably provided, a former column 4 spaced apart from the pulley base 18, and The main column 3 supporting the shaft 5 by bifurcating the former column 6 separated from the former column 4 and the latter column 6 sharing the shaft 5 with the former column 7 via a spring 7; The pulley stand 18, the former support column 4, the latter support post 6, and the serrated teeth 16 are arranged in this order, and the pulley stand 18 and the main column 3 are provided on the base 1, and the upper surface 8 of the former support post is bonded. In addition to increasing the area and providing the concave / convex teeth 11, the upper surface 12 of the latter column is made to have a small bonding area and the concave / convex teeth 13 are provided at positions facing the concave / convex teeth 11 to open and close the former column 4 and the latter column 6. The uneven teeth 11 and the uneven teeth 13 Engagement, coalescence surface between the uneven teeth 11 and the uneven teeth 13 as the plane, the former and the upper surface 8 of the post and the upper surface 12 of the latter struts share the shaft 5 along a circumferential line in repulsion of the spring 5 And form a shape that faces diagonally upward and is stationary. With this simple structure, the instrument can accurately open and close around the shaft 5 with no blurring, and the parts in each part can have vertical and horizontal distortions. The structure is such that there is no blurring of the tape 19. Next, when the handle 27 is operated to move the upper surface 12 of the latter strut along the circumferential line, the adhesive tape 19 forms the combined surface 17 above the intermediate point between the tooth tip and the tooth tip of the both strut upper surfaces. The raised raised palm portion 22 is accurately formed by the restoring force that maintains a straight line facing (see FIG. 7).

The second condition for forming the raised palm portion 22 at the end of the adhesive tape 19 of the present invention is that the adhesive tape 19 that tries to maintain a straight line is made to be a flat concavo-convex tooth by accurately opening and closing about the axis 5. 11 from the intersection of the extension line of the extension line of the eleven extension line, the latter convex tooth tip 24, and the flat convex / concave tooth 13 with the fine groove 26. The flat surfaces of the upper surfaces of the two supporting columns in such a shape maintain the angle at which the adhesive tape 19 is directed upward. Moreover, the angle which faces upward is adjusted with the length (radius) of both support | pillars. Further, the adhesive tape 19 straddling the upper surfaces of both supports is not torsionally strained and has a uniform tension, and is held on the upper surface 8 of the former strut and the upper surface 12 of the latter strut as flat surfaces. And On the other hand, when the adhesive area of the upper surface 12 of the latter support column is narrow, that is, when the adhesive tape 19 has a horizontally long and narrow adhesive surface and the adhesive surface is narrow, or when the adhesive tape 19 is used as a cutting blade for cutting the adhesive tape 19. When the adhesive area is small like this, the torsional distortion of the adhesive tape 19 occurs. When the former support column 4 and the latter support column 6 are brought close to each other, they may not be firmly bonded to the upper surface 12 of the latter support column and may be naturally separated or may be lowered without bending in the correct direction. However, when the bonding area of the upper surface 12 of the latter column is large, the above-mentioned matter does not occur, and even if the instrument is used continuously for a long time, the raised palm portion 22 is accurately formed at the end (see FIGS. 1 and 7). .

  9 to 11 show a second embodiment of the present invention, in which the uneven teeth 11 made flat and the uneven teeth 13 made flat as shown in FIGS. 1 and 2 are replaced with straight edges. When the former column 4 and the latter column 6 sharing the shaft 5 are opened and closed, the plate shape is formed as shown in FIG. The teeth of the square teeth 28 and the plate-shaped square teeth 28 are superposed on the top and bottom. By this operation, the pressure-sensitive adhesive tape 19 similarly forms the protruding palm portions 22 at the corners of the plate-shaped square teeth 28 on the upper surface 8 of the former support column. Further, the degree of polymerization of the plate-type square teeth 28 and the plate-type square teeth 28 is adjusted according to the use according to the hardness, thickness, width of the adhesive tape 19 and the like. The tooth thickness is also adjusted in the same way.

FIG. 12 shows a third embodiment of the present invention. Instead of the configuration in which the latter support column 6 is moved to open and close the former support column 4 and the latter support column 6 sharing the shaft 5, the former support column 4 is moved to the latter support column 6 sharing the shaft as shown in FIG. It is an adhesive tape cutter that opens and closes.

15 and 16 show a fourth embodiment of the present invention, and the configuration thereof is denoted by the same reference numerals as those shown in FIGS. A cover 32 for loading the adhesive tape 19 is provided by using the base 1 and the former pulley base 18 together. A pulley base 18 that holds the inner surface of the adhesive tape 19 inside the cover 32 and is rotatable, and a circle outside the cover 32. The periphery 1 is used as a base 1, and the connecting surface of the former support 4 on the lower surface of the concave and convex teeth 11 of the former support 4 is extended sideways as an end detention table 30 so that the pulley table 18 is grasped with a fingertip. . In addition, a handle 27 directly connected to the latter support 6 is provided in the continuation of the uneven teeth 13, the grooves 15, and the serrated teeth 16 on the upper surface 21 of the latter support, and directly hits the non-adhesive material 29. The concavo-convex teeth 11 having the flat surface 8 and the uneven teeth 13 having the flat surface on the upper surface 12 of the latter column sharing the shaft 5 are opened and closed by this operation. Even in such a rough usage method, the shaft 5 is shared and moved accurately so that it is always stable even when continuously used. Moreover, unnecessary surface bonding can be avoided by roughing the surface of the substrate 1 having a large number of small protrusions 31.

Further, if the adhesive tape 19 is pulled out and cut with the serrated teeth 16 without causing the opening and closing movement of the former support column 4 and the latter support column 6 sharing the shaft 5 of the present invention, it can be used as a straight adhesive tape 19. Moreover, the description in the said adhesive tape cutter and the said portable adhesive tape cutter is the structure of main frames, The position of the handle | steering-wheel 27, the exterior shape, a raw material, etc. change with safety aspects or designs.

FIG. 13 is a diagram showing a procedure for bonding and using the adhesive tape 19 having the raised palm portions 22 of the present invention to the adherend 29, and in front of the raised palm portions 22 formed on the upper surface 8 of the former column. When the straight adhesive tape 19 coming from the pulley 2 side (see FIG. 7 D) is lifted with the fingertips A and A, and the adhesive tape 19 of the required length is pulled out and cut with the serrated teeth 16, the adhesive tape 19 protrudes to the palm side. A protruding raised palm portion 22 including a flat portion 22B is formed outside the raised portion 23, the flat cut end 22A, and the fingertips A and A (FIG. 13A). Next, the pressure-sensitive adhesive tape 19 is made to face the adherend 29 with the fingertips A and A to press the flat portion 22B (FIG. 13B). Further, pressing the flat cut end 22A against the adherend 29 with the fingertip A causes the protruding portion 23 to protrude from the adherend 29 (FIG. 13C). The flat cut end 22A prevents the adhesive tape 19 from being peeled off from the end. If there is a flat cut end 22 </ b> A at the final end, if it does not become the end of the raised palm portion 22, it simply becomes a folded end. The projecting end of the projecting palm portion 22 ensures hermetic sealing and adheres from end to end in the same manner as a normal adhesive tape 19 in a straight line. And this convex end is hard to peel off in the horizontal direction. However, it can be easily picked and peeled upward with the fingertip.

FIG. 14 is a diagram showing a procedure for using the adhesive tape 19 for manually forming the folding portion of the present invention to the object to be adhered 29, and opening and closing movement of the former support column 4 and the latter support column 6 sharing the shaft 5. The portion of the straight adhesive tape 19 coming from the pulley 2 next to the protruding portion 23 in a state where the protruding palm portion 22 of the adhesive tape 19 straddles the corner of the detainment base 10 and the concave and convex teeth 11 (see FIG. 7)) is lifted with fingertips A and A (FIG. 14A), and without moving, the flat cut end 22A is pressed from the top to the bottom with the finger on the folding base 9 (FIG. 14B). The end of the adhesive tape 19 is a folded back end (FIG. 14C).

FIGS. 15 and 16 show the usage and top view of the portable adhesive tape cutter of the present invention, and the configuration thereof is indicated by the same reference numerals as those shown in FIGS. While holding the portable adhesive tape cutter loaded with the adhesive tape 19 and lightly swinging the wrist, the handle 27 that is directly linked to the latter support 6 is lightly struck against the object 29 to be adhered to the upper surface 12 of the latter support. When the uneven teeth 13 made into a certain plane and the uneven teeth 11 made into a plane on the upper surface 8 of the former support column sharing the shaft 5 are engaged with each other on the circumference around the shaft 5, the protrusion of the adhesive tape 19 The raised portion 23 has a shape straddling the corners of the concave and convex teeth 11 on the upper surface 8 of the former support column to form a convex raised palm portion 22 (see FIG. 7D). Next, a procedure for bonding this to the adherend 29 is shown (see FIG. 13). Further, a fine groove 26 is provided on the upper surface of the former strut 4 which is also used as an end detent 30 by extending the former strut 4 on the lower surface of the flat concave and convex teeth 11 on the upper surface 8 of the former strut. The effect of this part is that when the protruding joint portion 22 is formed using the adhesive tape 19 having a strong waist, the adhesive tape 19 straddling the concavo-convex teeth 11 corners is strong in the waist and strong in tension, so the restoring force is also strong. The flat cut end 22A bends from the lateral direction to the downward direction. At that time, the end holding table 30 receives the bending and makes it easy to form the raised palm portion 22.
