Abstract

An improved carton sealing sticker and cutter, comprising a closed housing body including all elements, a cutter device which can press blade to extend out during tape delivery to cut it off, a safety device which controls blade not to extend out while tape is not delivered for use, a guide plate guiding tape delivery and positioning it and a tape sleeve ring having brake function engaged to the housing body. All elements are connected in the closed housing body. The end part of tape roll 23 sleeving tape sleeve ring is drawn out to stick to guide plate and extends appropriately long. Blade 24 of cutter device may extend out for cutting only in use state; safety device in ordinary time controls blade not to extend out to ensure safety.

Claims

1. The improved structure of a carton sealing sticker and cutter, comprising:

a housing body comprising a basic frame and a cover, said basic frame comprising an arcuate front part with a mount hole on the upper wall thereof for mounting of a press button of cutter device, a vacancy in the lower part for locally extending a front and a back roller therefrom and the inside of the two side walls provided with slideways, a pivot and a suspension bar therebetween to link said cutter device;

a partition board dividing the frame into a front and back area;

a guide plate arranged behind said vacancy;

in the central area of the back side wall, a connection base of a tape sleeve ring comprising a hollow short barrel provided with three resilient hooks on its peripherial walls thereof to meet with catch holes of the barrel seat of said tape sleeve ring upon engagement;

a cutter device comprising a blade, a blade seat, a blade support, a press button and an extensible spring connected between two side walls of said basic frame front part wherein said blade is aimed at the gap of between said front and back rollers;

said blade being a little bit wider than tape with a cone-shaped cutting edge and joined to said blade seat by inserting its upper half part into an offering flute provided in said blade seat lower half part;

said blade seat being a flat jacket with a groove in its upper part in which the flange of end part of said blade support inserts to be connected thereby;

said blade support being somewhat U-shaped with packing plates on its two sides which insert into said slideways on said housing body two side walls and buckles on the ends of its two sides which insert sockets provided on two sides of said press button to link and position them thereby;

said press button comprising a suspension arm in the front part and an axis hole at the top end by which to be pivoted on said pivot connected between two side walls of said housing front part and being hung up by said suspension bar so that if said press button is pressed down, said blade may move down too but retreats immediately upon release of it;

a safety device pivoted on a pivot pin in said partition board and comprising an operation board, a torsional spring and a raised part on the back of said blade support;

said operation board having a central pivot hole to sleeve said pivot pin;

said torsional spring which too sleeves said pivot pin having one arm of itself resist against the front part of said partition board and the other arm against the front part of said operation board to enable said operation board to counter-balance beneath said raised part of said blade support to prevent downward movement of said blade;

said operation board'"'"'s rear part extending into said housing body back area wherein the tape when tightened may contact the rear end of said operation board and the generated friction force therebetween thus may force the front end of said opertion board to depart from said raised part of said blade support;

a guide plate being slightly arcuate in shape and arranged behind said vacancy and provided with raised edges for guiding tape delivery;

a tape sleeve ring being a hollow barrel one end of which is perpendicularly connected to the inner wall of said cover and, on the barrel body peripherial walls, comprising a few resilient pieces slightly outward developed and catch holes to which said three resilient hooks provided on said connection base of said housing body'"'"'s back side wall are engaged in order for tape roll to sleeve thereon, and covered by said cover;

with the above-described elements, this improved carton sealing sticker and cutter may overcome shortcomings of the conventionally used device.
