Abstract

Provided is a tape cutter comprising a housing comprising a rear spring, a forward opening, and a forward tape press roller; a tape dispensing unit urged by the spring and comprising a tape mount with an adhesive tape roll rotatably put thereon, and a push member projected from the opening; and a cutter unit pivotably mounted in the housing and comprising a front cutting blade and a top ridge. Placing the cutter on a surface to be sealed with the tape slightly projected from the opening and adhered on the surface and sliding the cutter will press the tape against the surface by the tape press roller for adhering thereto. After dispensing a desired length of the tape, pushing the push member will cause it to press down and pass over the ridge and press the blade to cut the tape off its roll with the spring being compressed.

Claims

1. A device for cutting an adhesive tape comprising:

a housing comprising a resilient assembly anchored onto a rear inner wall, a forward opening, a forward tape press roller, and a lateral shaft;

a tape dispensing unit urged by the resilient assembly and comprising a tubular tape mount with an adhesive tape in a form of roll rotatably put thereon, and a push member projected from the opening; and

a cutter unit comprising a rear tubular portion rotatably mounted on the shaft, a front cutting blade, and a top ridge disposed proximate the push member,

whereby placing the device on a surface to be sealed with an open end of the tape slightly projected from the opening and adhered on the surface and sliding the device on the surface in a direction will press the tape against the surface by the tape press roller for adhering the tape to the surface; and

after a desired length of the tape has been put thereon, pushing the push member in the same direction will cause it to press down and pass over the ridge and press the blade to cut the tape off its roll with the resilient assembly being compressed.

2. The device of claim 1, wherein the tape dispensing unit further comprises a tape guide below the push member for pressing onto the tape, and a platform proximate the tape guide, and wherein the platform and the tape guide are adapted to facilitate the pulling of the tape out of the device.

3. The device of claim 1, wherein the resilient assembly comprises a bar projected forwardly from the rear inner wall of the housing into a rear recess of the tape dispensing unit, and a coil spring put on the bar and biased between the rear inner wall of the housing and the recess.

4. The device of claim 1, wherein the pushing of the push member is stopped by an edge of the opening.
