1. Field of the Invention
The present invention relates to a food wrap such as a PVC wrap or an aluminum foil for storing food and a kitchenware for easily accessing and cutting the food wrap.
2. Description of the Related Art
To assure the freshness of food, prevent food from being contaminated, or cook food by baking, it is common to use food wraps to wrap food in household life or even in restaurants. In general, a food wrap usually includes a film made by PVC material or an aluminum sheet; regardless of PVC or aluminum, the food wraps are manufactured and packed in rolls and stored in a paper box for selling. Such paper box comes with a cutter with sawteeth; the wrap is pulled out to a desired length when it is in use, and the cutter will cut the food wrap. However, users have to hold the food wrap by one hand and the food or kitchenware by another hand for the sealing or packaging operation, and thus it is very inconvenient.
To overcome the aforementioned shortcoming, a so-called Food Wrap Cutter was introduced in the market, and the structure of a food wrap cutter is characterized in that the cutter has a main body with a transversally moving cutter, and the food wrap or aluminum foil is placed inside of the main body; after the wrap or foil is pulled out to a desired length, the user manually operates the cutter to move it transversally for cutting the wrap or foil. However, such a traditional food wrap cutter still has its shortcomings in that when the wrap is completely pulled out and cut by the cutter on one side, the stress is not even and the cutting end of the wrap will be softened and drooped without support, which will directly affect the evenness of the cutting, particularly for the thin and soft food wrap. When manually cutting the food wrap by the cutter transversally, the cutting end of the food wrap will curl and affect the evenness of the cutting since the width of the wrap is about 8˜22 inches and the stress is uneven. In other words, a food wrap (particularly when a plastic food wrap is cut) usually produces curls, wrinkles, or tangles; users have to use hands to reorganize or spread out the food wrap. Whiling reorganizing or spreading out the food wrap by hands, the food wrap may be contaminated by foreign substances or germs on the user's hands. When food is wrapped by such a food wrap, the food may get soured or rotten easily.
Further, traditional food wrap cutters have linearly arranged sawteeth with equal heights. The design of sawteeth with equal heights causes the food wrap to have several cutting actions by the sawteeth simultaneously when the food wrap is cut from left to right or from right to left, such that the force exerted from each sawtooth onto the food wrap is reduced. As a result, the food wrap cannot be pierced easily for cutting, and it is necessary to use larger force to complete the cutting. Furthermore, the cut end is usually not even. Therefore, traditional food wrap cutters still need further improvements.
The primary objective of the present invention is to overcome the inconvenience of placing a food wrap in a package box for its direct use.
The secondary objective of the present invention is to overcome the shortcoming of traditional food wrap cutters, including its uneven cut end due to the uneven stress of the cutting and the cutting end of the wrap is softened and drooped without support, which directly affects the evenness of the cut or even the smoothness; and the cut end generally has curls or wrinkles and thus it is inconvenient for cutting and packaging.
The third objective of the present invention is to overcome the shortcoming of traditional food wrap cutter that cannot cut the food wrap successfully and evenly.
Technical measures taken to solve the foregoing problems are described as follows:
The first technical measure taken is to set and fix a cutter transversally on a main body; when the food wrap is pulled out from the main body and attached along the whole cutter, external force is exerted to cut the food wrap.
The second technical measure taken is to improve the sawtooth structure of the cutter, which includes a plurality of sawteeth with different heights arranged in intervals to make the cutting of food wrap much easier.
The third technical measure taken is to include an upper panel and a lower panel; such upper and lower panels can control their ascending and descending movements. When the upper and lower panels are ascending, the lower panel covers the rear side of the cutter to protect the user hand from being cut while pulling out the food wrap. When the upper and lower panels are descending, the upper edge of the lower panel moves to a position lower than the cutter, and the upper panel will press on the food wrap to fix the food wrap in a position.
The fourth technical measure taken is to control the abovementioned ascending and descending movements of the upper and lower panels by using both hands to simultaneously press or release a guiding element each on both sides of the food wrap cutter.
Compared with the prior arts, the present invention achieves the first objective by cutting the thin and soft food wrap or aluminum foil evenly and smoothly. The present invention achieves the second objective by conveniently pulling out, cutting, and positioning the food wrap. The present invention achieves the third objective by providing a safe protection design, and cover the rear side of the blade of the cutter before the food wrap is pulled out in order to prevent the user hand from being cut when the food wrap is pulled from the rear end towards the front.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, in which:
To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

The present invention further comprises two guiding elements 2, two springs 26, a lower panel 4, an upper panel 6, and a cutter 5. A first hole 21 and a second hole 22 are disposed respectively on both ends of the guiding element 2, and the first and second holes 21, 22 have different diameters, but the interior of the guiding element 2 is connected with each other. The internal diameter of the second hole 22 is substantially corresponsive to the diameter of the axle rod 141. The spring 26 is placed into the second hole 22 and the axle rod 141 is passed into the second hole 22 and a wedge axle 25 is passed from the first hole 21 into the guiding element 2 and through the spring 26 into the guiding hole 142, so that the guiding element 2 is mounted onto the axle rod 141. In the meantime, the spring 26 is located between the end of the axle rod 141 and the bottom of the second hole 22. The axle rod 141 passes into the second hole 22 by adopting the sliding method so that the axle rod 141 can axially move between the guiding elements 2. A protruded base 24 is disposed on the rear side at the same ends of the guiding element 2 and the first hole 21, and the protruded base 24 has a horizontal guiding groove 241. The front sidewall of the guiding element 2 integrally forms a guiding wedge 23. When the guiding element 2 is pressed towards the base body 14, the spring 26 (as shown in
The lower panel 4 is substantially in the shape of a rod, and both ends of the lower panel 4 have a larger area, and a cam groove 41 is disposed in the section with a larger area. The cam grooves 41 on both ends of the lower panel 4 are symmetrical, and each cam groove 41 is provided respectively for passing the guiding wedge 23 of the guiding element 2 for the assembly. When the spring 26 is not compressed, the guiding wedge 23 is located at a high point 411 of the cam groove 41 (as shown in
The cutter 5 of the present invention has a series of sawteeth sets at the upper edge of the main body 1, and each set of sawteeth respectively has different heights. For example, the cutter of the present invention as shown in
The upper panel 6 of the present invention comprises a vertical section 62 and a horizontal section 61 coupled to form a L-shape structure, and both sides of the vertical section 62 have a vertical groove hole 621 and an enlarged hole 622 disposed at the lower end of the vertical groove hole 621 such that the pip 11 of the main body 1 can pass through the enlarged hole 622 and slide into the vertical groove hole 621 such that the upper panel 6 can relatively move vertically with respect to the main body 1. The lower surface of the horizontal section 61 preferably has a concave curved surface 611 corresponsive to the curvature of the upper surface of the base body 14.
