Description

Technical Field

[0001] This utility model relates to the field of paper cover technology, specifically a stackable rectangular paper cover with PHA coating. Background Technology

[0002] Currently, in the catering industry, in order to respond to the concept of energy conservation and environmental protection, a large amount of paper products are used. Rectangular paper lids and round paper lids are among the most commonly used lids. Traditional rectangular paper lids have a lid surface and an edge. After production, the structure is fixed and the edge cannot be folded. After production, when selling and transporting, rectangular paper lids cannot be stacked on top of each other. Otherwise, adjacent rectangular paper lids will be squeezed together, causing damage to the edge of the rectangular paper lid and affecting its later use. Utility Model Content

[0003] The purpose of this invention is to provide a stackable rectangular paper cover with PHA coating to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: it includes a paper cover surface and a paper cover edge, wherein the paper cover surface and the paper cover edge are integrally processed;

[0005] The paper cover edge includes a long edge, a short edge, and a connecting edge. Both ends of the long edge are embossed with a first fold pattern. A second fold pattern is embossed between the long edge and the paper cover surface. A third fold pattern is embossed between the short edge and the paper cover surface. A fourth fold pattern is provided between the long edge and the connecting edge, and between the short edge and the connecting edge.

[0006] In a further embodiment, a fifth fold pattern is embossed at the center line of the connecting edge.

[0007] In a further embodiment, the connecting edge and the short edge are bonded together with adhesive.

[0008] In a further embodiment, double-sided adhesive tape is adhered to both ends of the long extension edge.

[0009] In a further embodiment, the paper cover, long edge plate, short edge plate and connecting plate are all made of PHA coated kraft paper.

[0010] In a further embodiment, the side of the double-sided adhesive tape away from the long extension edge is provided with release paper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention presses down on the two long edges, causing them to press against the top of the paper cover under the action of the second fold. Under the action of the first fold, the two ends of the long edges bend around the first fold. At this time, under the action of the third and fourth folds, the two short edges are pressed against the paper cover, causing the two ends of the long edges to fold between the long and short edges, thus completing the folding of the paper cover edges. This allows the paper cover edges to fit snugly against the paper cover surface, and during subsequent transportation, they can be stacked together without damaging the edges.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This embodiment discloses a stackable rectangular paper cover with PHA coating, including a paper cover surface 1 and a paper cover edge 2, which are integrally processed. The paper cover edge 2 includes a long edge 3, a short edge 4, and a connecting edge 5. Both ends of the long edge 3 are embossed with a first fold 6, a second fold 7 is embossed between the long edge 3 and the paper cover surface 1, a third fold 8 is embossed between the short edge 4 and the paper cover surface 1, and a fourth fold 9 is provided between the long edge 3 and the connecting edge 5, and between the short edge 4 and the connecting edge 5. Figure 1 , Figure 2 and Figure 3As shown, the rectangular paper cover in this application consists of a paper cover surface 1 and paper cover edges 2. The paper cover edges 2 consist of long edges 3, short edges 4, and connecting edges 5. The paper cover surface 1, long edges 3, short edges 4, and connecting edges 5 are all made of kraft paper. PHA material is applied to the kraft paper using a coating process to form a thin film with waterproof, moisture-proof, and oil-proof functions on the surface of the kraft paper. There are two long edges 3 and two short edges 4, which are symmetrically designed around the four sides of the paper cover surface 1. The connection points between the long edges 3 and the short edges 4 and the paper cover surface 1 are respectively provided with second fold lines 7 and third fold lines 8 for folding. The long edges 3 and the short edges 4 can be rotated around the second fold lines 7 and the third fold lines 8 as the rotation axis. There are four connecting edges 5, which are located at the four corners of the paper cover surface 1. The connection points between the long edges 3 and the short edges 4 and the connecting edges 5 are designed with fourth fold lines 9. When the long extension edge 3 or the short extension edge 4 is folded, the connecting extension edge 5 is also folded. The first fold line 6 is designed at both ends of the long extension edge 3, dividing the long extension edge 3 into two triangles and a pentagon between the two triangles. When the two long extension edges 3 are pressed to the top of the paper cover surface 1, the triangular parts at both ends of the long extension edge 3 are flipped in the opposite direction under the action of the first fold line 6 and the fourth fold line 9, so that the triangular parts of the long extension edge 3 press on the pentagonal parts of the long extension edge 3. Under the action of the tension, the two short extension edges 4 tilt towards the top of the paper cover surface 1. Pressing the two short extension edges 4 makes them cover the triangular parts of the long extension edge 3, thus completing the purpose of covering the long extension edge 3 on the top of the paper cover surface 1 and the short extension edges 4 on the top of the long extension edge 3, which facilitates the overall folding. During subsequent transportation, they can be stacked together without damaging the extension edges.

[0020] The center line of the connecting edge 5 is embossed with a fifth fold 10. The connecting edge 5 and the short edge 4 are bonded together with glue. Figure 1 , Figure 2 and Figure 3 As shown, the fifth fold 10 is designed at the center line of the connecting edge 5, which allows the connecting edge 5 to be folded from the center line when the long edge 3 and the short edge 4 are at 90° with the paper cover surface 1. This allows the long edge 3 and the short edge 4 to form an enclosure at the top of the paper cover surface 1. After the connecting edge 5 is folded, the side of the connecting edge 5 that is close to the short edge 4 is glued to the short edge 4. This allows the long edge 3 to limit and fix the short edge 4 under the action of the connecting edge 5, thereby improving the structural stability of the enclosed paper cover edge 2.

[0021] Both ends of the long extension edge 3 are glued with double-sided adhesive tape 11, and release paper 12 is provided on the side of the double-sided adhesive tape 11 away from the long extension edge 3, such as... Figure 1 and Figure 4As shown, in this application, one side of the double-sided adhesive tape 11 is bonded to the triangular portions at both ends of the long extension edge 3, and the release paper 12 is designed on the other side of the double-sided adhesive tape 11. When the rectangular paper cover needs to be folded, the release paper 12 is peeled off. When the triangular portion of the long extension edge 3 is pressed onto the pentagonal portion of the long extension edge 3, the double-sided adhesive tape 11 can prevent the triangular portion and the pentagonal portion of the long extension edge 3 from separating after folding.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
