Abstract

A handheld tape dispenser includes a first shell, a second shell releasably secured to the first shell, a spring-actuated tape applying mechanism, a knife, a roll of tape, a roller member, and a tape press roller. The adhesive tape frictionally passes the roller member and a gap between the front platform and the tape press roller to extend out of a front opening. A rearward movement of the button moves blades downward to sever the adhesive tape.

Claims

1. A handheld tape dispenser comprising:

a first shell including a front opening, a tongue member, a top opening, a first hollow cylindrical member, a second hollow cylindrical member, a first rib, two second ribs with the first rib disposed therebetween, a receptacle, and a groove;

a second shell releasably secured to the first shell and including a front opening, a tongue member, a top opening, a receptacle, a first hollow cylindrical member joined the first hollow cylindrical member of the first shell, a longitudinal ridge, and a groove;

a spring-actuated tape applying mechanism including a frame, an oval opening with the second hollow cylindrical member projecting through, a cavity adjacent to the oval opening, and a pin;

a button disposed on both the top opening of the first shell and the top opening of the second shell;

a pressing member under the button;

a projection under the pressing member;

a front platform on both the receptacle of the first shell and the receptacle of the second shell, the front platform having a plurality of ridges on a top surface;

a tape core supported by the second ribs and having two aligned groove members on a bottom, the groove member being slidably placed on the first rib; and

two wings on two sides of the button respectively, the wings slidably disposed in the groove of the first shell and the groove of the second shell respectively;

a knife supported by the projection and including two front blades, a rear hollow cylinder pivotably put on the second hollow cylindrical member, a peg projecting downward from a bottom of the rear hollow cylinder into the cavity, a protuberance under the button, a first protrusion on an underside of the knife, and a second protrusion on the underside of the knife and being forward of the first protrusion;

a roll of tape wound convolutedly on the tape core and including an adhesive tape extending therefrom;

a roller member put on the pin; and

a tape press roller put on both the first hollow cylindrical member of the second shell and the first hollow cylindrical member of the first shell;

wherein the adhesive tape frictionally passes an outer surface of the roller member and a gap between the front platform and the tape press roller to extend out of both the front opening of the first shell and the front opening of the second shell;

wherein the longitudinal ridge presses the roll of tape;

wherein the peg is slidably disposed in the cavity;

wherein a rearward movement of the button moves both the front platform and the pressing member rearward to uncover both the receptacle of the first shell and the receptacle of the second shell, urge the pressing member against the protuberance, pivot the knife relative to the rear hollow cylinder, cause the first protrusion to press the adhesive tape against the ridges of the front platform, engage the second protrusion with the adhesive tape, move the blades downward into the receptacles to sever the adhesive tape, and adhesively secure a front end of the adhesive tape within both the first and second shells to the ridges of the front platform.
