Packing Tape Dispenser
The present invention discloses a packing tape dispenser which comprises a frame for mounting a roll of tape, a cutting blade fastened to a front end of the frame, the cutting blade not being able to move relative to the frame, a first plate slidably engaging the frame and being able to slide between a front location and a rear location, when the first plate being at the front location, a front edge of the first plate being positioned in front of the cutting blade for preventing the cutting blade to come into contact with other objects, and when the first plate being at the rear location, the front edge of the first plate being positioned behind the cutting blade for exposing the same for cutting, and a spring coupled to the frame and urging the first plate to slide toward the front location.
The present invention relates generally to dispensers for adhesive tapes, and, more particularly, to packing tape dispenser.
People that pack a large number of packages for shipping often use specialized tape dispensers, designed for sealing boxes with shipping tape using only one hand. One of such packing tape dispensers has a frame supporting a handle and a roll of tape. The frame also include a hinged level, when pushed, will force out a cutting blade over a stretch of the tape.
A common problem with conventional packing tape dispensers is that they do not cut tape very easily especially under less ideal situation due to their structural characteristics. Chief among them is that the tape is often suspended over a rather long stretch and can move. It is not easy to make a cut when an object can move back away.
As such, what is desired is a packing tape dispenser that can be easily applied.
SUMMARYA packing tape dispenser is disclosed which comprises a frame for mounting a roll of tape, a cutting blade fastened to a front end of the frame, the cutting blade not being able to move relative to the frame, a first plate slidably engaging the frame and being able to slide between a front location and a rear location, when the first plate being at the front location, a front edge of the first plate being positioned in front of the cutting blade for preventing the cutting blade to come into contact with other objects, and when the first plate being at the rear location, the front edge of the first plate being positioned behind the cutting blade for exposing the same for cutting, and a spring coupled to the frame and urging the first plate to slide toward the front location.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
The drawings accompanying and forming part of this specification are included to depict certain aspects of the invention. A clearer conception of the invention, and of the components and operation of systems provided with the invention, will become more readily apparent by referring to the exemplary, and therefore non-limiting, embodiments illustrated in the drawings, wherein like reference numbers (if they occur in more than one view) designate the same elements. The invention may be better understood by reference to one or more of these drawings in combination with the description presented herein.
DESCRIPTIONThe present invention relates to a packing tape dispenser. A preferred embodiment of the present invention will be described hereinafter with reference to the attached drawings.

At the sleeve 220′s pushed-back position as shown in
Because a gap between the top plate 220A and the bottom plate 220B can be made very small, for instance, about two millimeters, a tape strip stretched across the front end of the top plate 220A and the front end of the bottom plate 220B will be firmed suspended and very easy to be cut by the blade 210.
The above illustration provides many different embodiments or embodiments for implementing different features of the invention. Specific embodiments of components and processes are described to help clarify the invention. These are, of course, merely embodiments and are not intended to limit the invention from that described in the claims.
Although the invention is illustrated and described herein as embodied in one or more specific examples, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention, as set forth in the following claims.
Claims
1. A tape dispenser comprising:
- a frame for mounting a roll of tape;
- a cutting blade fastened to a front end of the frame, the cutting blade not being able to move relative to the frame;
- a first plate slidably engaging the frame and being able to slide between a front location and a rear location, when the first plate being at the front location, a front edge of the first plate being positioned in front of the cutting blade for preventing the cutting blade to come into contact with other objects, and when the first plate being at the rear location, the front edge of the first plate being positioned behind the cutting blade for exposing the same for cutting; and
- a spring coupled to the frame and urging the first plate to slide toward the front location.
2. The tape dispenser of claim 1 further comprising a handle mounted to the frame.
3. The tape dispenser of claim 1, wherein the cutting blade has a row of teeth in the front for cutting the tape.
4. The tape dispenser of claim 1, wherein the first plate is situated beneath the cutting blade in between the cutting blade and a tape strip.
5. The tape dispenser of claim 4 further comprising a second plate coupled to the first plate and situated above the cutting blade, a backward movement of the second plate also causing the first plate to move backward by the same distance, when the first plate being in the rear location, a front edge of the second plate being in front of the cutting blade for preventing to cutting blade to contact an object directly in front thereof.
6. The tape dispenser of claim 5 further comprising a nut-and-bolt set for fastening the cutting blade to the frame, and the first and the second plate having respective openings allowing the nut-and-bolt set to go through.
7. The tape dispenser of claim 6 wherein the opening on the second plate, together with the nut-and-bolt set, cause the first plate to stop at the front and rear locations.
8. The tape dispenser of claim 5, wherein the first and the second plate form a sleeve flanking the cutting blade.
9. The tape dispenser of claim 5, wherein the spring also urges the second plate to move forward.
10. The tape dispenser of claim 1 further comprising a smooth member attached to a bottom of the frame and having a width wider than a tape strip for pressing the same against a surface.
11. The tape dispenser of claim 1, wherein the cutting blade is formed out of the frame.
12. A tape dispenser comprising:
- a frame for mounting a roll of tape;
- a cutting blade fastened to a front end of the frame, the cutting blade not being able to move relative to the frame;
- a first plate slidably engaging and situated beneath the frame and being able to slide between a front location and a rear location, when the first plate being at the front location, a front edge of the first plate being positioned in front of the cutting blade for preventing the cutting blade to come into contact with other objects, and when the first plate being at the rear location, the front edge of the first plate being positioned behind the cutting blade for exposing the same for cutting;
