Description

  The present invention relates to an adhesive tape holder provided with a cutter blade and an adhesive tape holder with an opening / closing pedestal, and in particular, the holder main body can be placed in a standing position on a table, and a tab is formed at the end of the tape when cutting the tape. The present invention relates to an adhesive tape holder that can be used.

  The pressure-sensitive adhesive tape having adhesiveness on one side usually has a form wound around a core material in a cylindrical shape, and is used by drawing one end of the tape from the tape cylinder and cutting it into a desired length. In order to facilitate drawing and cutting of the tape end, this type of adhesive tape is used while being held in a tape holder with a cutting blade. Various types of tape holders are available on the market, but roughly divided, there is a cutting blade on the adhesive surface side of the drawn tape, and the tape end on the tape cylindrical portion side after cutting is the cutting blade. There are ones that are attached and temporarily held, and ones that are provided with a cutting blade facing the non-adhesive side (Patent Document 1). In the latter case, the end of the tape connected to the cut cylindrical part of the tape usually hangs away from the cutting blade, but this type is mainly wide enough to close the mouth of a parcel, for example. It is used as a wide and large diameter packaging tape.

Japanese Patent Application Laid-Open No. 2008-280125

Wide and strong adhesive tape for packaging is generally held in a tape holder with a cutting blade on the non-adhesive side of the tape. In this type, the tape end on the original side after cutting is the holder. Since this part hangs down, this part may stick to other unexpected places, or the tape cylinder after cutting may reversely rotate to the opposite side of the drawer side, making it impossible to easily pull out the tape end from the holder. .
In some cases, the non-adhesive surface portion of the tape end after cutting may adhere to the saw-toothed cutting blade, and in this state, it is difficult to form a tab at the tape end. When the end of the tape in use is pulled away from the cutting blade, there is a possibility that the hand may be damaged by the cutting blade.
In addition, this type of packaging adhesive tape holder is usually in an upright position when the adhesive tape is standing, that is, the central axis of the cylindrical portion of the tape is horizontal when it is placed on a desk or work table during use. However, the end surface (flat side surface) of the tape cylindrical portion is placed on the desk or table. In this state, for example, dust or dirt remaining on the desk or work table, small foreign matter, etc., adheres to the end surface of the cylindrical part of the tape, and this remains on the edge of the tape even after the tape is pulled out, and the tape is attached to the package Sometimes gives an unpleasant impression. Even when the tape holder is placed on the stand so that the cylindrical part of the tape is in an upright position, the tape holder is unstable because it does not have a special pedestal for installation, and there is slight vibration. There was an inconvenience of falling down due to shaking.

  The present invention provides an adhesive tape holder that prevents the adhesive tape from adhering to the cutting blade when the adhesive tape is pulled out from the holder main body portion and applied to the cutting blade of the main body portion for cutting. Objective.

  The present invention also enables the tape holder to be stably placed on a desk, work table, package, etc. so that the adhesive tape is in an upright position, and when placed on these, the tape holder is naturally cut. It is an object of the present invention to provide an adhesive tape holder with an opening / closing pedestal in which a tape-attached tab is securely formed at the end of the tape on the original side.

  According to the present invention, in the adhesive tape holder that cuts the adhesive tape by applying the non-adhesive surface side of the adhesive tape to the cutting blade of the holder main body, the cylinder is closer to the cylindrical portion of the adhesive tape than the cutting blade. An adhesive tape holder comprising a tape pressing member that is swingably attached to the holder main body at a position and biased so as to be pressed against a non-adhesive surface of the adhesive tape drawn out from the cylindrical portion of the adhesive tape; can get.

  Further, according to the present invention, there is provided an adhesive tape holder with an opening / closing pedestal for supporting the cylindrical portion of the adhesive tape so as to be in an upright state, wherein the end opposite to the cutting blade formed at one end of the holder main body portion A base plate pivotally attached to the base and extending toward the cutting blade; a tongue piece hingedly connected to a tip of the base plate and bent at a predetermined angle toward the lower surface of the base plate; and the tongue A claw portion provided on the inner surface of the base plate in the vicinity of the hinge connecting position of the one portion and having an inclined surface with respect to the inner surface of the base plate, the base plate with respect to the lower surface of the holder main body portion When the base plate is closed with respect to the holder main body, the tape dripping tip after cutting is pushed up by the base plate to the claw portion, and the adhesive surface A self-adhesive tape holder with an open / close pedestal that can be worn in the form of a tab It is subjected.

  According to the present invention, when the adhesive tape is cut against the cutting blade of the holder main body portion, the tape end portion after the cutting does not adhere to the cutting blade and hangs down from the holder main body portion. Tape drawing and tape end tab formation are facilitated.

  Furthermore, according to the present invention, the tape holder on which the adhesive tape is mounted can be placed on a table or the like so that the tape is in a standing posture, and the tape holder is placed on a desk, work table, luggage or the like. A tab can be formed at the cut end of the tape simply by placing it, which makes it easy to pull out a new tape and to peel off the tape attached to a package or the like.

It is a perspective view of the adhesive tape holder with an opening-and-closing base which concerns on Example 3 of this invention. It is a partial expansion perspective view of the adhesive tape holder with an opening-and-closing base which concerns on Example 4 of this invention. It is a side view of the state which mounted the adhesive tape holder with an opening-and-closing base which concerns on Example 4 of this invention on the mounting base. It is a partial side view of the adhesive tape holder which concerns on Example 1 of this invention. It is a partial side view of the adhesive tape holder which concerns on Example 2 of this invention.

  As described above, the adhesive tape for packaging held in this type of tape holder is manually pulled out from the cylindrical portion of the tape to a desired length, and then the non-adhesive surface of the tape is pressed against the cutting blade at the end of the holder. At this time, the tape cutting portion connected to the cut cylindrical portion of the tape sometimes gets stuck to the cutting blade by being caught by a saw-tooth cutting blade. In such a state, it is not possible to form a tab on which the tape is adhered at the end of the tape after cutting, and in order to form the tab, the adhesive tape hangs down and separates from the cutting blade after cutting. It needs to be in a different form. Hereinafter, various embodiments of the tape release mechanism will be described with reference to FIGS. In the following examples, tape holders corresponding to packaging adhesive tapes having a wide width and strong adhesive strength are shown.

Example 1
First, the first embodiment shown in FIGS. 4A and 4B will be described. A tape guide roller 8 is pivotally supported on the main body 7 adjacent to the cutting blade 9 of the holder main body 7, and the guide roller The arm 21 of the tape press-contact member mentioned later is pivotally attached to the both ends of the shaft support part 8. The tape pressure contact member has a configuration in which the arm 21 is longer than the radius of the guide roller 8 and a pressure contact roller 22 having a length over the width of the adhesive tape 20 is pivotally supported at the tip of the pair of arms 21. A coil spring (not shown) having one end fixed to the pivot of the tape guide roller 8 is attached to the base portion of the arm 22 (the shaft support portion of the arm 21). A tape regulating roller 16 is pivotally supported on the side plate 2 of the main body 7 at a position closer to the cylindrical portion 3 side of the adhesive tape 20 than the position of the tape guide roller 8. The tip end of the arm of the tape pressing member and the pressing roller 22 are arranged slightly offset from the center position of the tape guide roller 8 toward the cutting blade 9 and are always away from the cutting blade 9 by the spring force of the coil spring. It is biased to rotate. Reference numeral 23 denotes a stopper pin provided on the holder main body 7, and after cutting the tape by the cutting blade 9 (described later), it contacts the arm 21 of the pressure contact member to regulate the position of the arm 21 after cutting the tape.

  The adhesive tape 20 drawn out from the tape cylindrical portion 3 passes between the tape guide roller 8 and the tape regulating roller 16 and is directed to the cutting blade 9 while being in contact with the tape guide roller 8 and the pressure contact roller 22 of the tape pressure contact member. However, at this time, the pressure roller 22 is biased toward the cutting blade 9 against the spring force of the coil spring by the extension force of the pressure-sensitive adhesive tape 20 and presses against the non-stick surface of the pressure-sensitive adhesive tape 20. After the adhesive tape 20 is cut, the arm 21 is rotated toward the stopper pin 23 by the action of the coil spring with the center of the tape guide roller 8 as a fulcrum, thereby connecting the tape on the original side connected to the cut cylindrical portion 3. The cutting end portion is pulled away from the cutting blade 9 and extends away from both the rollers 8 and 22 or hangs down. FIG. 4B shows the state at this time. When the arm 21 and the pressure roller 22 have a predetermined weight, they may be rotated toward the stopper pin 23 by their own weight regardless of the spring force of the coil spring. In this case, the coil spring Can be omitted.

(Example 2)
FIGS. 5A and 5B are diagrams showing another embodiment 2 of the automatic tape release mechanism. In the second embodiment, a pair of arms 21 are pivotally supported by the holder main body 7 at a position closer to the cylindrical portion 3 side of the adhesive tape 20 than the tape guide roller 8, In addition, a pressure roller 22 is pivoted so as to connect the pair of arms. Further, between the tape guide roller 8 and the pressure contact roller 22, a tape regulating roller 16 is pivotally supported on the side plate 2 partially shown in the holder main body portion 7. These rollers 8, 16, and 22 are parallel to each other in axis, and the length of the pressure contact roller 22 is the same as the width of the adhesive tape 20 as in the first embodiment. The adhesive tape 20 is drawn out from the cylindrical portion 3 toward the cutting blade 9 in contact with each roller so as to sew between the rollers 22, 16, 8. The regulating roller 16 will be further described later with respect to other embodiments described later.

  In the second embodiment, the tape pressing roller 22 is always urged toward the tape regulating roller 16 so as to contact the adhesive tape 20 at a position closer to the tape cylindrical portion 3 than the position of the regulating roller 16. Specifically, a suitable coil spring or other urging means is provided between the base portion of the arm 21 supporting the pressure roller 22 and the holder main body portion 7 so that the arm 21 is inclined in the illustrated state. It is biased toward the regulating roller in a downward state. In the state before the tape is pulled out, the pressure roller 22 is in contact with the regulating roller 16 via the adhesive tape 20. Therefore, in the second embodiment, the tape restricting roller 16 also serves as a stopper for the rotating arm 21.

  When the tip of the adhesive tape 20 is grasped and pulled out to the cutting blade 9 side in this state, the arm 21 of the tape release member is kept in contact with the non-adhesive surface of the pressure roller 22 and the tape 20 by the extension force of the tape 20. It is biased in the direction away from the regulating roller 16 against the spring force biasing 21, that is, toward the tape cylindrical portion 3. After the tape is cut, the extension force of the tape disappears. Therefore, the arm 21 is again biased toward the regulating roller 16 by the spring force, and the cut tape 20 is pulled back from the cutting blade 9 by the pressure roller 22 at the tip. As shown in FIG. 5B, the leading end of the tape hangs down. The pulling-off force of the tape caught on the cutting blade 9 at the time of cutting the tape is weaker than the rotation-induced force of the tape cylindrical portion 3 due to the expansion of the adhesive tape 20. In the second embodiment described above, the arm 21 may be biased toward the regulating roller 16 by the weight of the arm 21 and the pressure roller 22 without using the spring means as the biasing means of the arm 21.

(Example 3)
Next, the Example of the adhesive tape holder with an opening-and-closing base which concerns on this invention is described. As shown in FIG. 1, the holder body 7 of the adhesive tape holder 1 of the third embodiment has a side plate 2 on one side, and a cylindrical portion 5 on which the cylindrical portion 3 of the adhesive tape 20 is loosely fitted on the side plate 2. A small end plate 6 is formed and is spaced from the side plate 2 at a certain distance. The side plate 2 and the end plate 6 are connected by an upper shoulder plate 10 having a lateral width slightly exceeding the width of the tape. A tape guide roller 8 is rotatably supported between the side plate 2 and the end plate 6 at a lower position of the holder main body 7, and a saw-toothed cutting blade 9 is provided at the further end. The non-adhesive surface of the adhesive tape drawn out from the tape cylindrical portion 3 is guided while being in contact with the tape guide roller 8 and is brought into contact with the cutting blade 9 to be cut to a desired length.
The above configuration is an example of a normal adhesive tape holder, and there are various other shapes of the holder, which are not directly related to the main part of the present invention, and the non-adhesive surface of the adhesive tape is It is one structural example of the type which faces a cutting blade.

  Referring to FIGS. 1 and 2, an openable / closable base plate 11 extending toward the cutting blade is pivotally attached to the lower end of the side plate 2 at the end opposite to the cutting blade 9. The base plate 11 is lower than the bottom edge of the side plate 2, that is, the bottom of the holder main body 7 (herein referred to as “closed”) at a predetermined angle with respect to the bottom, for example, approximately 30 ° from the bottom. The base plate 11 is rotatable about the pivot 13 to the open state (open state). When the tape holder 1 is placed so that the lower surface of the base plate 11 is in contact with a desk, work table, luggage, etc., the base plate 11 is in a closed state (closed state) with respect to the holder main body 7. As a result, the tape holder 1 is placed on a table or a load such that the central axis of the cylindrical portion 3 of the side plate 2, that is, the cylindrical portion 3 of the adhesive tape loosely fitted to the cylindrical portion, is horizontal. Further, by closing the base plate 11 in this manner, a tape tab 15 (FIGS. 2 and 3) attached to the end of the cut tape is formed, which will be described later. 1 shows a state in which the base plate 11 is opened, and FIGS. 2 and 3 show a state in which the base plate 11 is closed with respect to the main body portion 7. FIG.

  On the inner surface of the side plate 2 on one side, a tape regulating roller 16 having a small diameter is rotatably provided adjacent to the tape guide roller 8 and between the roller 8 and the cylindrical portion 5 of the side plate 2. The adhesive tape 20 is drawn from the cylindrical portion 3 between the tape guide roller 8 and the tape regulating roller 16 to the cutting blade 9 side, but the adhesive surface of the tape 20 contacts the tape regulating roller 16, so that the tape is The circumferential surface of the tape regulating roller 16 is a rough surface with a large number of small grooves so as not to adhere strongly to the regulating roller 16. The tape regulating roller 16 is related to the action of forming the tab 15 at the end of the tape after cutting. The tape holder 1 with an opening / closing pedestal of Example 3 shown in FIG. 1 is not provided with the tape release mechanism described in FIGS.

Example 4
In the fourth embodiment, as shown in FIG. 2, the pressure contact roller 22 of the tape release mechanism described in FIGS. 5A and 5B is provided between the tape cylindrical portion 3 and the regulating roller 16, and its function. As described with reference to FIG. 5, an adhesive tape holder with an opening / closing pedestal having a structure in which a tape releasing mechanism is not provided as in the third embodiment described above can also be used. As a modification of the fourth embodiment, a tape releasing mechanism as shown in FIG.

  Referring again to FIGS. 1 to 3, a tongue piece portion 17 having a plate width substantially the same as that of the base plate 11 is pivotally supported at the tip of the base plate 11 so as to be capable of bending. 2 and 3, a thick pillow member 25 is fixed to the lower surface of the base plate 11 at a position slightly rearward (from the base plate pivot side) from the tip of the base plate 11. Yes. In a state where no external force is applied, the tongue piece portion 17 extends along the base plate 11, but when the base plate 11 is closed with respect to the holder main body portion 7, for example, by placing it on the mounting base 26 or the like, The inner surface of the tongue piece 17 contacts the tape guide roller 8 and bends downward with respect to the base plate 11 at a certain angle (see FIG. 2), and the bending operation stops at this position. That is, the tongue piece portion 17 does not bend further downward than this stationary state, and when the tape holder 1 is placed on a stand or a load in a standing posture, the bottom portion of the holder body portion 7 is pivoted on the base plate 11. The lower end tips of the landing portion 13 and the tongue piece portion 17 and the pillow member 25 on the lower surface of the base plate 11 come into contact with the table 26 and the upper surface of the luggage, whereby the pivot portion 17a of the tongue piece portion 17 The base plate 11 is bent inwardly toward the inside, and the tip end of the base plate 11 is slightly inclined with respect to the surface of the mounting table 26 and the like in such a manner that the tip side is biased to the inside of the holder main body 7 (FIG. 3).

  A claw portion 19 having a lateral width substantially the same as the tape width is provided on the inner surface of the base plate 11 at a position slightly close to the tongue piece portion 17. In this embodiment, the claw portion 19 is formed with an inclined surface 19a whose upper surface is inclined to the rear side (base plate pivoting side) at an angle of approximately 60 °. These tongue piece portion 17 and claw portion 19 are also related to the action of forming the tab 15 at the tape end portion after the tape is cut.

  Next, the operation of forming the tab 15 at the end of the tape connected to the cut cylindrical portion 3 will be described. First, when the tape holder 1 is held by hand and the tip of the tape is pulled out and the adhesive tape 20 is cut to a desired length by the cutting blade 9, the tape end connected to the tape cylindrical portion 3 after cutting is separated from the cutting blade 9, In addition, due to the nature of this type of adhesive tape, the adhesive surface side is bent and hangs down so as to be slightly concave as a whole (FIG. 1). In this state, when the base plate portion of the holder 1 is placed on the mounting base or pushed toward the holder 1 so as to close the base plate 11, the tape end portion that hangs down from the inner surface of the base plate 11 to the claw portion 19. The portion reaching the inclined surface 19a is biased toward the curved side of the tape, and the adhesive surface of the tape end is attached so as to be overlapped. Thus, the tab 15 on which the tape is adhered is attached to the tape. Formed at the end. When the tape is pulled out next time, the tab portion is manually held and pulled out, and cut to a desired length by the cutting blade 9. When the tape is attached to a package such as a parcel, the tape may be peeled off from the tab 15 at a later date, and the end of the tape hanging from the holder after cutting is unnecessary in other parts as in the past. There is no inconvenience such as adhesion.
