Description

[Detailed description of the invention] De Spencer The present invention relates to a dispenser, in particular a dispenser made of plastic material, flake or paper material. This invention relates to a dispenser for rolls of material such as:

1 bean king 1 Plastic sheet materials and paper sheet materials for consumer use are usually rolled into cylindrical forms. a container having a lid flap that can be opened to reveal the sheet material; It is stored in a container or carton. When opening the lid flap, the edge of the carton opening A serrated knife ridge is formed adjacent to the . The material is unrolled from a cylindrical former. , when the appropriate length is reached, it is pulled out across the knife and that length is extracted from the remaining amount. disconnected.

In such cartons it is necessary to prevent material rotation during cutting operations. . Therefore, both hands are required for the work. If the material is not held from rotation lateral edges extending at an angle of 90 degrees to the sheet material. is usually not possible, and this is undesirable.

The sheet material is a flexible plastic sheet material (such as plastic food wrap). If the roll of material is held unrotated, the material will cut During or as a result of work, there is a tendency to bunch or fold. In that case, the material Avoid unnecessary or time-consuming activities before using them for their intended purpose. You need to open it or fold it open. Or wastefully discard cut material rolls. Then you need to cut the material to that length again.

Another early proposal was Australian Patent Specification No. 503352. A typical example is a material roll dispenser. collect the roll The loaded carton will be discarded (regardless of whether or not it is equipped with the knife described earlier). ), the roll is a dispenser that allows individual lengths of material to be cut from the roll. placed inside the server. Such dispensers are provided primarily for aesthetic reasons. It consists of a container body with a lid or cover through which the material is drawn. It was equipped with an elongated frontage to obtain. A straight edge is provided adjacent to the elongated frontage and The material can then be drawn across its edges to cut a length from the roll. too If the roll inside the dispenser is not restrained from rotating during cutting, In some cases, it is not possible to cut across the edge of the material at a 90 degree angle; The edges of the food were often ragged and torn.

Such dispensers are generally more suitable for materials such as paper or flakes. Yes, and if the material is a plastic film, the cut edges may be frayed during the cutting process. This is because plastic films are flexible and cannot be stretched. , due to normal elongation during cutting operations. In addition to ruffling the cut edges, Plastic films, by their nature, can fold if care is not taken. It is necessary to fold it open before use.

In an attempt to solve the problem referred to, the serrated knife is often It has been replaced by a straight edge through which the material is drawn. The completed design The dispenser was an upmarket product for the early packaging containers discussed earlier. It was just a cheap replacement.

British Patent Specification 1407507 describes how a roll of plastic film can be freely rotated. A dispenser and joiner is disclosed that includes a container for holding the dispenser and joiner. this the container has a lid, and the film is captured between the lid and the upper edge of the container during the cutting operation; The lid is held closed against the container. held movably by the knife lid; This allows it to be moved along the lid to cut individual lengths of material from the roll. Therefore, two tasks are involved. The movement of the knife stretches the material. The rolls therefore have a tendency to rotate inside the container. This is the structure of the dispenser. structures that make the cutting process difficult or prevent the edges of the cut material (and (also the leading edge of the material extending from the wall). shall be different.

Australian Patent Specification No. 544232 discloses that plastic film is Dispensers specifically intended for dispensing from bottles are described. This display The sensor has a hot wire that is normally hidden. The hot wire melts the material in the exposed state and separates the material. ・This device requires a power source for the hot wire. Moreover, they emit unpleasant odors, which are often toxic and depend on the plastic material involved. bring to life
