ABSTRACT:
The present invention provides a box sealer for attaching adhesive tape in an L-shape on corners of a box for medical drugs, cosmetics, etc. The box is first received at a rectangular corner furnished on a top surface of the box sealer, and adhesive tape of a predetermined dimensions is sent out from below and is cut. By sliding attachment plates at the corner of one side and at the bottom of the box, the adhesive tape is attached in the L-shaped form. Knurled rollers for sending out the adhesive tape are furnished in tandem, and one of the rollers is rotated by twice as many revolutions as the other roller. Further, a microswitch for detecting the box and rotating a motor is mounted near the rectangular window of the housing, and a pair of operating pins of the microswitch are provided in parallel.
