Description

Technical Field

[0001] The utility model relates to the technical field of paper holders, in particular to a foldable paper holder. Background Art

[0002] Paper trays have good shockproof, impactproof, anti-static and anti-corrosion effects, and are pollution-free to the environment. They are more conducive to the export of manufacturers' products and are widely used in packaging in electronics, electrical appliances, computers, mechanical parts, industrial instruments, handicraft glass, ceramics, toys, medicine and other industries.

[0003] Paper trays, also known as pulp molding, are made from carton scraps, newsprint, white pure wood pulp, etc. After being crushed and mixed into a slurry with a certain concentration, they are formed by vacuum adsorption on a customized CNC mold based on product design, and then dried to form environmentally friendly paper products of different types and uses.

[0004] However, the inventors found in the actual research and development process that this one-piece molded paper tray needs to be molded by a mold. In order to smoothly demold, it is inevitable to make a draft angle treatment when designing the mold, and the internal cavity forms a "trumpet mouth", which has a major functional defect:

[0005] 1. When paper trays are used to package medium-to-large products with regular shapes such as "cylindrical, rectangular, and cube-shaped", they can only touch the tangent area between the paper tray and the product, and most of the other areas of the product cannot be protected;

[0006] 2. When this paper tray is placed in a packaging box, it cannot fit in with the six internal surfaces of the packaging box, leaving a large space for movement. As a result, the paper tray is easily damaged during the packaging reliability test, and it will cause damage to the product, thus reducing the company's production efficiency and economic benefits.

[0007] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first described.

[0036] Please also read Figure 5 , is an integrally formed paper support structure 100 in the prior art. Due to the integrally formed paper support structure, the surface of the accommodating area for accommodating the product is an inclined surface 1001; when the product is loaded into the paper support, only part of the product rests on the inclined surface 1001 of the accommodating area, so that the tangent line 1002 rests between the product 200 and the surface of the accommodating area; the paper support of this structure not only has a small abutting area for the product, but also the product can easily puncture the paper support, which seriously limits the reliability and service life of the paper support.

[0037] Please also read Figures 1 to 4The foldable paper tray 10 provided in the embodiment of the present application is now described. The foldable paper tray 10 comprises: a bottom plate 11 and a folding plate 12.

[0038] There are at least two folding plates, at least two of which are integrally formed at the edge of the bottom plate, and each folding plate can be folded up relative to the bottom plate; each folding plate 12 is provided with a first abutting protrusion 125, and each first abutting protrusion 125 is provided with a first abutting surface 126 for abutting against the surface of the product; when the folding plate 12 is folded up relative to the bottom plate 11, the first abutting surface 126 remains vertically arranged relative to the bottom plate 11.

[0039] Specifically, by folding the folding plate relative to the bottom plate, the first abutting surface of each folding plate can be arranged vertically relative to the bottom plate, and the first abutting surface is used to abut the surface of the product; compared with the one-piece paper tray used in traditional technology, the abutting surface used to abut the product is not an inclined surface, thereby increasing the abutting area for the product, making the protection performance of the product better and effectively reducing the product damage rate; at the same time, since the abutting area for the product is increased, the impact force of the product on the paper tray can also be reduced, thereby improving the reliability of the paper tray when carrying the product.

[0040] In more detail, when the folding plate 12 is not folded up relative to the bottom plate 11, the first abutting protrusion 125 is arranged at the top of the folding plate 12; when the folding plate 12 is folded up relative to the bottom plate 11, the folding plate 12 and the bottom plate 11 can enclose a accommodating area 13 for supporting the product, and the first abutting protrusion 125 is arranged facing the accommodating area 13.

[0041] It can be understood that, through the arrangement of the folding plate, when the folding plate is not folded relative to the bottom plate, the folding plate and the bottom plate are both in a horizontal arrangement. At this time, the first abutting protrusion is arranged on the upper surface of the folding plate, and only after the folding plate is folded relative to the bottom plate, the first abutting protrusion will switch following the displacement of the respective folding plates; after the folding plate is folded, the first abutting protrusion will be arranged facing the side of the accommodating area, so that the first abutting surface is arranged vertically relative to the bottom plate, thereby effectively eliminating the technical defect of the one-piece molded paper tray having a draft bevel in the traditional technology.

[0042] In some embodiments of the present application, between the opposite side surfaces of the first abutment portions 125 of at least two folding plates 12, one is provided with a first snap-fitting protrusion 127, and the other is provided with a first snap-fitting groove 128; when at least two folding plates 12 are folded up relative to the bottom plate 11, the adjacent sides of the two first abutment portions 125 abut against each other, and the first snap-fitting protrusion 127 is inserted into the first snap-fitting groove 128.

[0043] Preferably, the first abutting surface 126 is disposed at the top of the first abutting protrusion 125 , the peripheral side surface of the first abutting protrusion 125 is a first draft bevel 1251 , and the first snap-fitting protrusion and the first snap-fitting groove are disposed on the first draft bevel 1251 .

[0044] Exemplarily, in the first abutment protrusions of at least two folding plates, a first snap-fitting protrusion is arranged on the first draft slope on one side of the first abutment protrusion, and correspondingly a first snap-fitting groove is arranged on the first draft slope on the other side opposite to the first abutment protrusion; when at least two folding plates are folded relative to the bottom plate, the adjacent first draft slopes of the two first abutment protrusions can abut against each other, and the first snap-fitting protrusion can be inserted into the first snap-fitting groove; the first snap-fitting protrusion and the first snap-fitting groove are cooperated to complete the assembly and fixation between the two folding plates.

[0045] In some other embodiments of the present application, the plurality of folding plates 12 include a front folding plate 121, a rear folding plate 122, a left folding plate 123 and a right folding plate 124. The front folding plate 121, the rear folding plate 122, the left folding plate 123 and the right folding plate 124 are integrally formed corresponding to the front, rear, left and right sides of the bottom plate 11. Folding guide lines 14 are provided between the front folding plate 121, the rear folding plate 122, the left folding plate 123 and the right folding plate 124 and the bottom plate 11. By presetting the folding guide lines, the subsequent folding operation of the folding plates can be facilitated, and position deviation is less likely to occur.

[0046] Specifically, the bottom plate 11 is provided with a first boss 111, and the peripheral side surface of the first boss 111 is a second draft bevel; when the folding plate 12 is folded up relative to the bottom plate 11, the first draft bevel 1251 can abut against the second draft bevel. Between the peripheral side surface of the first boss 11 and the peripheral side surface of the first abutting portion 125, one is provided with a second snap-fitting protrusion 114, and the other is provided with a second snap-fitting groove 129; when the first abutting protrusion 125 abuts against the first boss 11, the second snap-fitting protrusion 114 can be inserted into the second snap-fitting groove 129. The assembly method and function of the second snap-fitting protrusion and the second snap-fitting groove are the same as those of the first snap-fitting protrusion and the first snap-fitting groove, and will not be repeated here.

[0047] In some other embodiments of the present application, a convex portion 112 and / or a concave portion 113 for supporting the product is provided on the top of the first boss 111; the arrangement of the convex portion and the concave portion can be changed according to the actual shape of the bottom of the product.

[0048] Specifically, the bottom plate 11 and the plurality of folding plates 12 can enclose any one of a square paper tray, a rectangular paper tray, a cylindrical paper tray or a polygonal paper tray. The bottom plate 11 and the plurality of folding plates 12 can enclose any one of a square receiving area, a rectangular receiving area, a circular receiving area or a polygonal receiving area for receiving products. It can be seen that the shape of the paper tray and the shape of the receiving area can be changed according to actual use needs by changing the size of the bottom plate and the folding plates.

[0049] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
