Triangular-knife-edge V-shaped-knife-holder fresh-keeping film using device

Abstract

The invention relates to using devices of fresh-keeping films, in particular to a triangular-knife-edge V-shaped-knife-holder fresh-keeping film using device. At present, fresh-keeping films are pulled out from a carton and placed on a rack of the carton to be forcibly broken by pulling for use, so that the problem of unsafety is caused. A fresh-keeping film box with a cutting function is provided, and the problems of laboriousness during cutting and inconvenience in pulling of the fresh-keeping films in the process of actual use exist. The triangular-knife-edge V-shaped-knife-holder fresh-keeping film using device comprises a knife rest, a knife holder, a tong and an opening and closing device, the knife rest is fixed below the upper-portion front end, and the knife holder is fixed above the lower-portion front end of the opening and closing device; the fresh-keeping films extend out from an outlet in the middle of the lower portion of the opening and closing device, forwards go through the upper side of the knife holder and the lower side of the knife rest and are pulled outside the device; the knife edge of a toothed knife is formed by arranging two-bevel-edge triangles, the top end on a long groove is V-shaped or inverted-V-shaped, a tooth top is not lower than a cutting assistance point, and the tong is sheet and is fixed below the upper portion of the opening and closing device.

Description

technical field [0001] The invention relates to a daily necessities of fresh-keeping film, in particular to a device for using the fresh-keeping film. technical background [0002] Fresh-keeping film is widely used in people's daily life.

Problems solved by technology

[0003] The above-mentioned usage has the following problems in operation, 1 is an inconvenient problem

It is not easy to break the plastic wrap on the rack of the carton, especially for plastic plastic wrap with large stretchability.

2 is the problem that the carton can not withstand repeated tossing and cannot be reused. The carton can only be used once for about 30 meters and then it is useless.

3. The tip of the tooth is exposed on the outside of the package, which is very unsafe.

[0004] The design of the cut-off plastic wrap box that I proposed in the application of Chinese patents 96229952.9, 2005200474358, 2005200478715, and 200520006577X, in actual use, found that there are two problems.
