Description

Technical Field

[0001] This utility model belongs to the field of environmentally friendly packaging technology, and more specifically, it relates to a simple snap-on packaging paper tray. Background Technology

[0002] Packaging paper trays, also known as pulp molding, are packaging products made from renewable fibers (such as waste paper, pulpboard, sugarcane pulp, bamboo pulp, etc.) through a series of processes to form a specific three-dimensional structural shape. They are widely used as inner cushioning packaging for industrial products (such as electronic products), food packaging (such as egg trays and fruit trays), and agricultural seedling trays.

[0003] Most existing packaging paper trays use a single tray, but some loaded items may require temporary covering for protection depending on the usage scenario. Integrated paper trays with top covers cannot be flexibly converted from single-tray paper trays.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a simple snap-on packaging paper tray in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a simple snap-on packaging paper tray to solve the problem that integrated paper trays with top covers and single tray paper trays cannot be flexibly converted.

[0006] The purpose and function of this utility model's simple snap-on packaging paper tray are achieved through the following specific technical means:

[0007] A simple snap-on packaging paper tray includes a lower tray and a cover tray. Both the lower tray and the cover tray have extension platforms around their periphery. A flip strip and a support strip are respectively provided on the extension platform at one end of the lower tray. The flip strip and the support strip are distributed on the left and right sides. A rolled edge is provided on the extension platform at the corresponding end of the cover tray. The rolled edge can be inserted into the cavity formed in the flip strip.

[0008] Furthermore, a positioning hole is provided on the extension platform at the other end of the lower tray, and a recess corresponding to the positioning hole is provided on the extension platform of the cover plate, with limit protrusions provided on both sides of the recess.

[0009] Furthermore, a curved strip is provided inside the recess, and each end of the curved strip is provided with a pressing end. The pressing end abuts against the inner wall of the limiting protrusion. A button is provided at the bottom of the curved strip, and a through hole is opened at the bottom of the recess, through which the button passes.

[0010] Furthermore, a folded groove is formed at the center of the top of the curved strip.

[0011] Furthermore, both the lower tray and the cover plate have multiple reinforcing ribs formed on their periphery.

[0012] Furthermore, a support platform is provided inside the lower tray, and the support platform is recessed in the middle and has a ventilation window.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The split design at the end of the lower tray forms a support strip and a flip strip. The rolled-up space inside the flip strip allows the rolled edge of the cover plate to be inserted, enabling the lower tray and the cover plate to be temporarily combined, and also to be removed for separate use. This flexibility reduces production costs and improves practicality. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 7 As shown:

[0029] This utility model provides a simple snap-on packaging paper tray, including a lower tray 1 and a cover plate 2. Both the lower tray 1 and the cover plate 2 are provided with extension platforms 3 on their periphery. Both the lower tray 1 and the cover plate 2 can be used as individual paper trays. Furthermore, both the lower tray 1 and the cover plate 2 have multiple reinforcing ribs 4 formed by concave and convex shapes on their periphery, which increases the structural strength of the items being carried.

[0030] The lower tray 1 is provided with a support platform 103. The support platform 103 is recessed in the middle and has a ventilation window 104. The support platform 103 can bear items, and the ventilation window 104 can play a role in heat dissipation and moisture prevention.

[0031] The extension platform 3 at one end of the lower tray 1 is provided with a flip bar 101 and a support bar 102. The extension platform 3 is broken in the middle from the edge, and the two sides of the break bend in different directions to form the flip bar 101 and the support bar 102 distributed on the left and right. The extension platform 3 at the corresponding end of the cover plate 2 is provided with a rolled edge 201. The rolled edge 201 can be inserted into the cavity formed in the flip bar 101. The cover plate 2 can be moved laterally from the side, so that the rolled edge 201 can be inserted into the flip bar 101 from the side. The support bar 102 can guide and support the rolled edge 201. The lower tray 1 and the cover plate 2 can be temporarily combined, and can also be removed for separate use. The flexibility reduces production costs and improves practicality.

[0032] The other three sides of the extension platform 3 are folded inward to improve edge strength.

[0033] A positioning hole 105 is provided on the extension platform 3 at the other end of the lower tray 1. A recess 202 corresponding to the positioning hole 105 is provided on the extension platform 3 of the cover plate 2. Limiting protrusions 203 are provided on both sides of the recess 202. After the cover plate 2 is combined with one end of the lower tray 1, it can be closed by inserting the recess 202 into the positioning hole 105 to temporarily seal the items packaged inside the lower tray 1. The limiting protrusions 203 can limit the position of the recess 202.

[0034] Since the limiting protrusions 203 are protrusions pressed outward from both sides of the recessed grid 202, they are all made of fiber material. During long-term use, they are prone to deformation and flattening when passing through the positioning hole 105. To solve this problem, in this embodiment, a curved strip 206 is provided inside the recessed grid 202. Both ends of the curved strip 206 are provided with extrusion ends 207. The extrusion ends 207 abut against the inner wall of the limiting protrusions 203. A button 205 is provided at the bottom of the curved strip 206. A through hole 204 is opened at the bottom of the recessed grid 202. The button 205 passes through the through hole 204. When the limiting protrusions 203 are compressed and retracted, the extrusion ends 207 are pushed to make the center of the curved strip 206 bend downward. If the limiting protrusions 203 do not return to their original position, the button 205 is pressed to make the curved strip 206 expand and push the limiting protrusions 203 to return to their original position.

[0035] In this embodiment, the bending strip 206, the extrusion end 207, and the button 205 are all made of paper fiber. The button 205 is a strip of paper that is rolled up and glued to the bending strip 206. The bending strip 206 has a folding groove 208 at the top center, so that when the two sides of the bending strip 206 are squeezed inward, the bending strip 206 bends downward, avoiding the bending strip 206 bending in the opposite direction and affecting the restoration.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
