Description
Technical Field
The utility model relates to an improved invention of a paper box, in particular to an improved invention of a fresh-keeping paper box.
Background
Most of the existing fresh-keeping boxes are made of plastic materials, and due to the characteristics of integral forming and manufacturing of the fresh-keeping boxes and the materials, the sealing performance of the fresh-keeping boxes and the flatness of the upper edges of the peripheries of the fresh-keeping boxes can be guaranteed, and then the sealing performance after food materials are packaged can be guaranteed after the fresh-keeping boxes are covered with cover films. The application aims at providing the fresh-keeping lunch box which has good sealing performance and is easy to manufacture and can replace plastic materials.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a leakproofness good, make simple and easy fresh-keeping carton.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: the fresh-keeping paper box comprises a square box body and is characterized in that: the box body adopts a paper to cut and fold into the shaping, and the box body is including the bottom surface and connect in bottom surface lateral wall all around, and the lateral wall upper end is equipped with round horizontal flanging, be equipped with the tectorial membrane layer on the inside and horizontal flanging of box body, this tectorial membrane layer is stereotyped the box body to form upper end open-ended sealed chamber, the box body sets and seals the epiphragma of sealed chamber upper end open-ended, and this epiphragma matches the involution with the tectorial membrane layer on the horizontal flanging when using.
The horizontal outward flanges of the adjacent side walls are in seamless connection and are encircled to form the circle of horizontal outward flanges.
The laminating layer adopts plastic uptake shaping in box body inside and level turn up the edge outward.
The beneficial effects of the utility model are that the preservation carton after the improvement is equipped with the tectorial membrane layer on the inside and horizontal flanging of box body, and this tectorial membrane layer is stereotyped the box body to form the sealed chamber of upper end open-ended, will eat during the use and put into the box body, reuse epiphragma seals up deposit, can accomplish the freshness protection package who eats the material, and the leakproofness is good, effectively prolongs the shelf life, and wherein the box body adopts a paper to cut and convert into, and stereotypes by the tectorial membrane layer, and the preparation is simple and easy, and the shaping is high-efficient.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the box structure of the present invention.
Fig. 3 is an expanded view of the box structure of the present invention.
Detailed Description
The structure of the present invention is shown in the attached drawings, and the details thereof will be further described with reference to the attached drawings. In this embodiment, this fresh-keeping carton, including square box body, the box body adopts a paper to cut and converts into the shaping, and used paper is for drenching the membrane paper, and the box body is including bottom surface 1 and connect in bottom surface 1 lateral wall 2 all around, and 2 upper ends of lateral wall are equipped with round horizontal flanging 3, and the flanging level sets up be convenient for follow-up tectorial membrane and with the involution of epiphragma 4, be equipped with the tectorial membrane layer on the inside and horizontal flanging 3 of box body, this tectorial membrane layer is stereotyped the box body to form upper end open-ended sealed chamber, the box body sets and seals the epiphragma 4 of sealed chamber upper end open-ended, and this epiphragma 4 matches the involution with the tectorial membrane layer on the horizontal flanging 3 when using.
The utility model discloses a forming process cuts out bottom surface 1 of box body and connects in bottom surface 1 lateral wall 2 all around with the paper, form the crease between bottom surface 1 and the lateral wall 2, roll over out horizontal flanging 3 with lateral wall 2 upper end again, form the crease line between horizontal flanging 3 and the lateral wall 2 upper end, arrange it in the forming die intracavity at last and finalize the design, and cover the film on bottom surface 1, lateral wall 2 and horizontal flanging 3, make its shaping, and form the sealed chamber of upper end open-ended. When the preservation paper box is used, food materials are placed in the sealing cavity, and the cover die and the film coating layer on the horizontal outward flanging 3 are sealed to seal the sealing cavity.
As a further improved specific implementation mode, the horizontal flanging 3 of each adjacent side wall 2 is in seamless connection and encloses to form the circle of horizontal flanging 3, and preferably, the ports of the horizontal flanging 3 are connected by 45-degree oblique edges.
As a specific embodiment of further improvement, the film coating layer is formed in the box body and on the horizontal outward flange 3 by plastic suction, so that the forming is quick, and the film coating is smooth.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
