Technical Field

The utility model relates to a plastic wrap box design field, in particular to plastic wrap cutting box that prevents plastic wrap return.

Background

Plastic packaging products, which are generally made of ethylene as a master batch through polymerization, are classified into three main types: the first is polyethylene, abbreviated as PE; the second is polyvinyl chloride, PVC for short; the third is polyvinylidene chloride, PVDC for short; from the physical perspective, the preservative film has proper oxygen permeability and moisture permeability, the content of oxygen and moisture around the preserved product is adjusted, and dust is blocked, so that the preservation period of the food is prolonged.

However, the use of the preservative film is not very convenient, and people often suffer from the trouble that the preservative film is cut continuously and is not easy to tear out when using the preservative film; the preservative film box is convenient for consumers to use and can be transported as soon as possible, the preservative film box can not only protect the preservative film from being damaged by the outside, but also keep the preservative film clean, and meanwhile, the cutting sawteeth are arranged, so that the use of the consumers is convenient.

But at the same time, the prior preservative film box has some problems: after the preservative film is cut off by using the cutting saw teeth, the preservative film usually returns to the preservative film box due to the elasticity of the preservative film, and the preservative film box needs to be opened to pull out the preservative film when the preservative film is used next time, so that the operation is inconvenient.

Detailed Description

The following description will be made in detail with reference to the accompanying drawings 1 to 4 and examples; the following examples are provided to illustrate the present invention, but are not intended to limit the scope of the present invention.

As shown in fig. 1, a preservative film cutting box for preventing preservative film from returning comprises a box body 10 and a box cover 11, wherein the box body 10 and the box cover 11 are both in a cuboid shape, one long edge of the box cover 11 is connected to one long edge of the box body 10, and the box cover 11 can rotate along the long edge to achieve an opening and closing effect; the other long side of the box cover 11 is provided with a rectangular bent portion, the lower end of the bent portion is provided with a serrated blade 110, the serrated blade 110 is mainly used for cutting the preservative film, the outer side wall of the box body 10 adjacent to the bent portion is provided with a preservative film limiting device 12, the preservative film limiting device 12 is connected with the outer side wall of the box body 10 through gluing, as shown in fig. 4, when the box cover 11 is closed, the preservative film limiting device 12 is contacted with the rectangular bent part, the box body 10 and the box cover 11 are both printed with the reinforcing strips 111, the reinforcing strips 111 are machine-printed and have certain depth, the rigidity of the cardboard paper is enhanced by mainly enabling the cardboard paper to generate deformation, so that the cardboard paper is not easy to deform, the semicircular cutting marks 100 are arranged on two sides of the box body 10 in the length direction, the semicircular shape is inward when the semicircular cutting marks 100 are pressed down, and the semicircular shape can be used as an axis when the preservative film rotates, so that the preservative film is prevented from moving left and right.

As shown in fig. 2, the plastic wrap limiting device 12 is a rectangular hard board provided with a "W" shaped groove, the upper half of the "W" shaped groove of the rectangular hard board protrudes outwards, and the outward protruding part of the upper half of the "W" shaped groove of the rectangular hard board is a limiting piece 120; the material of plastic wrap stop device 12 is thicker hardboard, can effectively promote the life-span of plastic wrap case on the one hand, and on the other hand, the elasticity is great behind the thicker hardboard deformation, makes protruding spacing piece 120 inseparable with the laminating of lid 11 like this, and the fixed action that plays the plastic wrap is just better.

As shown in fig. 3, the angle between the limiting sheet 120 and the cardboard paper is 30 ° to 40 °, and considering the property of the cardboard, if the angle between the limiting sheet 120 and the rectangular cardboard is too small, the resilience of the limiting sheet 120 is too small, and the contact part with the box cover 11 does not fix the preservative film well; if the included angle between the limiting piece 120 and the rectangular cardboard is too large, the cardboard fibers will break and lose elasticity, so the included angle is preferably 30-40 ° according to the experimental results.

As shown in fig. 4, when the box cover 11 is in the closed state, the serrated blade 110 is located 5-6mm below the limiting piece 120, according to the working principle of the cling film box, the serrated blade 110 must be located below the limiting piece 120, and meanwhile, the serrated blade 110 cannot be too far away from the limiting piece 120, otherwise, the cut is prone to be irregular.

During the use, put into the plastic wrap box with the plastic wrap book, tear the head of plastic wrap to detain with lid 11, lid 11 presss from both sides tight plastic wrap with spacing piece 120, presses down semi-circular cutting trace 100 after that and makes the semicircle inwards buckle, makes the semicircle be as the axle stationary blade of plastic wrap, tears the plastic wrap and upwards lifts after that, makes cockscomb structure blade 110 cutting plastic wrap, cuts the plastic wrap and just can use, and the plastic wrap can not return simultaneously, has made things convenient for next use.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
