Description

  The present invention relates to, for example, a tape cutter that affixes an upper lid of a cardboard box with a packing tape, and in particular, by folding the end of the tape after cutting, the tape can be pulled out and peeled off at the next use. It relates to what has been made easier.

  Conventionally, tape cutters for adhesive tape and packing tape have been provided. As an example, as shown in FIG. 23, the packing tape cutter includes a cylindrical core 1 </ b> A that rotatably supports a wound adhesive tape 10 on the back of the main body 1. Further, the tape feeding portion 1B in front of the main body 1 is provided with bifurcated tape guides 1C and 1D that hold the both ends of the tape being fed so as not to be removed, and a cutter C on the upper side portion of the tape guide.

  In the pasting operation by the tape cutter, the tape tip section cut by the cutter C is first pulled out by hand. Then, the tape front-end | tip part is affixed on side part S1 of cardboard box DB. Then, the upper lids F1 and F2 of the cardboard box DB are pasted, and the opposite ends of the upper lids F1 and F2 are pulled out and pasted to a place where they have come out, and the tape is cut and pasted to the side surface S2 on the opposite side. is there.

  The conventional tape cutter has the following problems. The adhesive tape that closes the top lid of the cardboard box is stuck to the tip of the tape. For this reason, when peeling an adhesive tape, the peeling operation from the edge of an adhesive tape cannot be performed smoothly, but there existed a problem which made the opening operation | work of a cardboard box inefficient. Furthermore, there is a problem that the tape tip portion is in close contact with the tape cylindrical portion and is difficult to peel off (especially in the case of a transparent tape) at the next use.

  The present invention has been made on the basis of the problems found in the above tape applicator, and the object of the present invention is to facilitate the adhering operation and the exfoliating operation of the adhesive tape for closing the upper lid of the cardboard box. An object of the present invention is to provide a tape cutter which can be folded back at the part.

  In order to achieve the above object, a tape cutter according to claim 1 of the present invention includes a cylindrical core portion that rotatably supports a wound adhesive tape on the rear side, and both ends of the tape fed below the front tape feeding portion. A bifurcated tape guide that holds the tape guide so that it does not come off, and a tape press portion that has a tip upwardly disposed at an intermediate position of the tape guide, and a main body that has a pin support portion above the tape feeding portion, and A bifurcated tape folding guide wall provided so as to cover the outside of the pin support portion of the main body is pivotally supported by a common pin so as to be rotatable in the vertical direction, and the tape folding upper guide wall below the pin support portion The lower guide wall is equipped with an upper limit stopper, a lower limit stopper, and a tape guide that regulate the rotation angle of the cutter. A tension spring is provided to urge the stopper, and the dimension between the tape folding lower guide walls is provided with a folding lever body that is slightly narrower than the tape width. After the tape is cut, the lever section of the folding lever body is rotated upward. The inner surface portion of the cutter tip that is pivotally supported between the tape folding upper guide walls is brought into contact with the tape pressing portion of the main body to press the tape tip portion to form a non-adhesive portion at the tape tip portion. It is characterized by this.

  The tape cutter according to claim 2 of the present invention is the tape cutter according to claim 1, wherein in order to deal with variations in tape width, both ends of the cutter blade tip protrude a small amount and the intermediate portion is concave. It is a feature.

  In the case of the tape cutter of the present invention, first, the lever part of the main body and the folding lever body are simultaneously held with the right hand, and the tip part of the wound adhesive tape is held with the left hand and pulled downward. Subsequently, when the leading end of the wound adhesive tape is pulled back and pulled between the lower guide walls with the left hand, the adhesive tape is applied to the cutter and pulled upward. When the cutter is rotated to the upper limit position, the cylindrical part of the wound adhesive tape is pressed so that the tape does not move, and the cutter is lowered to cut the adhesive tape. After the tape is cut, the cutter returns until it comes into contact with the cutter lower limit stopper by the restoring force of the tension spring. At this time, the tip of the tape adheres to the tip blade of the cutter with adhesive tape glue, and the tape tape adhesive surface comes into light contact with the tape guide and is held in a curved state on the inner surface of the tip of the cutter blade. Subsequently, when the cylindrical core part at the bottom of the main body is changed to the left hand, the lever part of the turning lever body is turned upward with the right hand, and the tip of the cutter is brought into pressure contact with the tape pressing part of the main body. A non-adhesive part is formed. Therefore, the non-adhesive part which turns back here is reliably formed in the tape end in preparation for the next time.

  In addition, in order to deal with variations in the tape width, by projecting a small amount at both ends of the cutter blade tip and making the middle part concave, the tape end and the entire tape will not peel off from the cutter tip when cutting the tape. It is attached to the cutter blade tip.

  According to the tape cutter of the present invention, it is possible to surely form the non-adhesive portion by folding back the tape end in preparation for the next time. Moreover, when peeling a tape, it can be easily peeled by being pinched with a fingertip. Therefore, the cutting operation and the folding operation of the tape end can be performed simply and easily with a simple operation. Thereby, a tape sticking and the folding | returning part of a tape end can be formed quickly and accurately.

  Furthermore, since both ends of the cutter tip are protruded by a small amount, even when the tape width varies, the tape end or the entire tape does not peel from the cutter tip when cutting the tape, and can be firmly attached to the cutter blade tip.
