TWM595414U - Reinforced structure at corner of paper dinner plate - Google Patents

Abstract

A reinforced structure at the corners of a paper dinner plate, which is designed to cut all the marks on the middle of the four corners of the dinner plate before forming the dinner plate. The two sides of the mark form a tacky part, so that when the paper device presses out the shape of the tray on the mold, the tacky parts on each side of the corner cut are superimposed, and then the hot press is applied to make the two stick together At the same time, the periphery of the top of the dinner plate is pressed out by the mold and slightly bent downward, so that the structure of the corner of the paper dinner plate is more firm and strong without the problem of slack.

Description

Reinforced structure at corner of paper dinner plate

The present invention relates to a reinforced structure at the corner of a paper dish tray, which is to make a cut in the middle of the paper device forming the corner of the dish tray, and press out the tray shape on the mold, The two sides of the cut are overlapped and applied with heat and pressure to be bonded together, thereby obtaining corners that will not be loosened again, so that the structure of the paper tray is stronger and more reliable.

The general paper container is made of food paper. In addition to the printing process, it also needs to be cut and shaped to complete. At the same time, the container is resistant to oil and water and can last for a long time. Drinks and soups are usually filled with a very thin layer of plastic (PE (polyethylene), PP (polypropylene), or PLA (polylactic acid)) after printing on paper and before cutting. At the same time, the so-called laminating film is made into a waterproof dinner plate after the paper is cut and then stamped by the die.

When the above-mentioned die punches the paper into a plate, the paper at the four corners of the plate must be stamped into a body to form a body, the area of the area will be reduced, so the corner will be made Wrinkles are formed to facilitate reduction, as shown in patents No. 142536, 194597, 214688, 244471, 254087 or 267331 of the Patent Publication of the Republic of China, that is, the four corners of the dinner plate are first punched out of the creases, so that the stamping The perfect wrinkle can be formed on the tray only after the tray is taken out.

However, the creases and creases that form the four corners of the plate are just the shrinkage formed for modeling. The strength of the structure there does not have a substantial strengthening effect, but also affects the strength of the entire plate shape, such as : Most users use their thumb to hold the edge of the tray, while the other four fingers hold the tray by holding the bottom of the tray. After the dishes are filled with food, they support the tray The weight of food, in addition to the aforementioned four fingers must hold the plate, the thumb should tightly hold the edge of the plate, which will cause the edge of the plate where the thumb is held, will be turned out by the maximum force. The wrinkles in the corners of the plate on both sides of the upper edge are loosened due to the force, which makes it difficult for the plate to maintain its original shape and easily deform.

Or, as long as the plate is slightly pressed by the external force from top to bottom, the wrinkles there will loosen, causing the depth of the plate to become shallow, resulting in the soup of the dishes contained in the plate. Outflow of doubts.

Secondly, even though the dinner plate of the aforementioned Patent No. 244471 has a horizontally turned-out and folded-down edge around the dinner plate in an attempt to strengthen the overall structure of the dinner plate, the corners of the dinner plate The place is still formed by wrinkles, so it is still impossible to overcome the problem of the wrinkles being loosened by the force.

In addition, when recycling paper trays, the creases and creases in the four corners of the tray are very likely to get stuck with rice dregs or other debris, which will also affect the recovery and cleaning operations.

The reason is that in order to improve the aforementioned four corners of the paper tray formed by the wrinkled structure, it cannot provide the strength to maintain the original shape of the tray and affect the recycling operation after use. The new model is provided at the four corners of the tray The corners are cut with cuts, so that the sides of the cuts at the corners of the seasonal tray form a stacking part that can be stuck together, making the formation of the tray not only easier, At the same time, the strength of the corners after the two stacks of adhesive parts are bonded is more reliable and stable, thereby strengthening the strength of the dinner plate and making it less likely to deform.

The technical solution adopted by the new model to solve its technical problems is to set up a paperware tray for folding up on four sides, and make the paperware in the middle of each corner forming the tray have cut marks, so that the The two sides of the cut become the overlapping parts that are stuck together when forming the corner of the plate.

In the above solution, the periphery of the dinner plate is provided with an outwardly extending and slightly downwardly folded edge.

Therefore, when the four sides of the cut are formed by folding the four sides of the tray to form each corner, the two stacks of sticking on both sides of the cut The natural stacking and gluing together keeps the corners of the dinner plate from loosening, making the dinner plate less likely to deform.

Figure 1 is a schematic diagram of the creative tray paper tray when it is unfolded.

Figure 2 is a perspective schematic view of the paper tray created by the author.

Figure 3 is the superimposed schematic view of the two stacks of sticky corners of the corner of the paper plate of this creation.

Please refer to FIG. 1, a tray made of paper provided a 1, the sheet 1 has not been punched to the front of the tray 1 'at the four corners thereof are cut to be cut are each provided with 11 of the cut, and make the two sides of the cut 11 to form the adhesive part 12,13.

Thus, with the second and third Please shown by the cuts 11 when folded upwardly by the die stamping, i.e. dish is formed around the four sides of a sheet 1 ', but also in the four sides folded At the corners of the formed dish 1, the two stacks of adhesive parts 12, 13 are naturally superimposed on each other, and at the same time, the two stacks of adhesive parts 12, 13 are fixed together by hot pressing to complete the dinner plate 1. Structural modeling.

Therefore, the corners of the dinner plate 1 are bonded by the two stacks of adhesive parts 12, 13 to form a corner that will not be loosened at all, so that the sides of the dinner plate 1 are not prone to valgus deformation Therefore, the overall structural strength of the dinner plate 1 is stronger, which allows the user to hold the dinner plate 1 holding food more stably and less likely to deform.

Secondly, there is an edge 14 which is turned outwards and slightly folded downward at the periphery of the tray 1, and the two stacks of adhesive parts 12 and 13 at each corner are also bonded together, so the edge 14 is strengthened by the inclined folding The strength of the four sides of the dinner plate 1 makes the four sides of the dinner plate 1 less prone to valgus, and at the same time allows the dinner plate 1 to withstand relatively larger forces without deformation.
