Description

Technical Field

[0001] This utility model relates to the field of packaging, specifically to a paper tray. Background Technology

[0002] Paper trays are widely used in the logistics, warehousing and transportation industries. Paper trays used to hold heavier products (such as batteries) typically consist of an outer frame and an inner liner tray placed in the outer frame. The inner liner tray has a receiving groove for holding the product. Inner liner trays made of pulp molding have advantages such as easy shaping, low cost, recyclability and easy degradation. However, such inner liner trays have low strength. When used to carry and transfer heavier products such as batteries, the structure is easily damaged, causing the product to fall and resulting in loss. Utility Model Content

[0003] To address the issue of insufficient strength in existing paper trays, this utility model provides a new type of paper tray.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A paper tray includes an inner tray and an outer frame. The inner tray is placed in the outer frame. The front of the inner tray is divided into multiple receiving slots by several crossbeams and several longitudinal beams. The crossbeams and longitudinal beams form transverse grooves and longitudinal grooves on the back of the inner tray, respectively. A transverse support rod is embedded in each transverse groove and a longitudinal support rod is embedded in each longitudinal groove. The transverse support rods and longitudinal support rods are connected in a cross shape. The back of the inner tray is provided with multiple auxiliary longitudinal grooves, which are located on the back of the receiving slots. An auxiliary longitudinal rod is embedded in each auxiliary longitudinal groove.

[0006] Preferably, the bottom surface of the horizontal support rod is flush with the bottom surface of the inner lining tray, and the bottom surface of the vertical support rod is flush with the bottom surface of the inner lining tray.

[0007] Preferably, the transverse support rod has a first notch on the side facing the front of the inner lining tray, and the longitudinal support rod has a second notch on the side facing away from the front of the inner lining tray. The positions where the transverse support rod and the longitudinal support rod intersect perpendicularly are mutually avoided by the cooperation of the first notch and the second notch.

[0008] Preferably, each transverse groove is perpendicularly connected to all auxiliary longitudinal grooves, and the side of the transverse support rod facing away from the front of the inner lining tray is provided with a third notch for each auxiliary longitudinal rod position.

[0009] Preferably, each receiving slot has two auxiliary longitudinal slots on its back side.

[0010] Preferably, each end of the auxiliary longitudinal bar facing the front side of the inner lining tray is provided with a positioning groove, and a vertical support column is embedded in each positioning groove. The back of the inner lining tray is provided with a vertical slot for accommodating the vertical support column corresponding to each positioning groove position.

[0011] Preferably, the front of the inner lining tray is formed by a crossbeam, a longitudinal beam, and the outer edge groove wall around the inner lining tray to create four receiving slots.

[0012] This utility model has the following beneficial effects:

[0013] By embedding transverse and longitudinal support rods on the back of the inner liner tray, the wall of the receiving groove is supported. An auxiliary longitudinal rod is embedded on the back of the receiving groove, which supports the bottom surface of the receiving groove. The transverse support rods, longitudinal support rods, and auxiliary longitudinal rods strengthen the support of the inner liner tray and improve the load-bearing capacity of the paper tray.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 3 As shown, this embodiment discloses a paper tray, including an inner tray 1 and an outer frame 2. The inner tray 1 is made of paper material or a composite material containing paper material, preferably made by pulp molding process. The outer frame 2 is made of paper material, and the inner tray 1 is placed in the outer frame 2.

[0020] The front of the inner tray 1 is divided into multiple receiving slots 4 by several crossbeams 3 and several longitudinal beams 5. The receiving slots 4 are used to place items (such as batteries). The crossbeams 3 and longitudinal beams 5 form transverse grooves 6 and longitudinal grooves 7 on the back of the inner tray 1, respectively. Each transverse groove 6 contains a transverse support rod 8, and each longitudinal groove 7 contains a longitudinal support rod 9. Since adjacent receiving slots 4 are separated by crossbeams 3 or longitudinal beams 5, the transverse support rods 8 fill the transverse grooves 6 on the back of the crossbeams 3, and the longitudinal support rods 9 fill the longitudinal grooves 7 on the back of the longitudinal beams 5. The four edges of the inner tray 1 are usually quite strong. The four edges of the inner tray 1, combined with the crossbeams 3 and longitudinal beams 5, make the walls of each receiving slot 4 less prone to deformation, increasing the overall strength of the inner tray 1.

[0021] Preferably, the transverse grooves 6 and longitudinal grooves 7 have the same depth, and each transverse groove 6 is perpendicularly connected to all longitudinal grooves 7. A first notch 11 is provided on the side of the transverse support rod 8 facing the front of the inner lining tray 1, and a second notch 12 is provided on the side of the longitudinal support rod 9 facing away from the front of the inner lining tray 1. The perpendicular intersections of the transverse support rod 8 and the longitudinal support rod 9 are connected in a cross shape through the cooperation of the first notch 11 and the second notch 12, and they avoid each other, thus ensuring that the bottom surface of the transverse support rod 8 is flush with the bottom surface of the inner lining tray 1, and the bottom surface of the longitudinal support rod 9 is flush with the bottom surface of the inner lining tray 1. The longitudinal support rod 9 and the transverse support rod 8 avoid each other through the cooperation of the first notch 11 and the second notch 12, rather than using segmented transverse support rods 8 or segmented longitudinal support rods 9. This helps reduce the number of transverse support rods 8 and / or longitudinal support rods 9, and helps ensure the support effect at the intersection of the crossbeams 3 and longitudinal beams 5 of the inner lining tray 1. In other embodiments, the avoidance structure of the longitudinal support rod 9 and the transverse support rod 8 is not limited to that described in this embodiment.

[0022] The back of the inner liner tray 1 is also provided with multiple auxiliary longitudinal grooves 13. The depth of the auxiliary longitudinal grooves 13 is less than the depth of the longitudinal grooves 7. The auxiliary longitudinal grooves 13 are located on the back of the receiving grooves 4. Each auxiliary longitudinal groove 13 is embedded with an auxiliary longitudinal rod 14. Each transverse groove 6 is perpendicularly connected to all the auxiliary longitudinal grooves 13. The transverse support rod 8 is provided with a third notch 15 for each auxiliary longitudinal rod 14 on the side facing away from the front of the inner liner tray 1. Preferably, each receiving groove 4 has two auxiliary longitudinal grooves 13 on its back, that is, each receiving groove 4 has two auxiliary longitudinal rods 14 on its back, which is used to support the bottom surface of the receiving groove 4 and prevent the bottom surface of the receiving groove 4 from deforming due to load.

[0023] In addition, each end of the auxiliary longitudinal rod 14 facing the front side of the inner lining tray 1 is provided with a positioning groove 16. A vertical support column 17 (which can be a hollow column or a solid column, and can be a cylindrical column, a square column, or other shapes) is embedded in each positioning groove 16. The back of the inner lining tray 1 is provided with a vertical slot 10 for accommodating the vertical support column 17 corresponding to the position of each positioning groove 16. The vertical support column 17 is concealed between the auxiliary longitudinal rod 14 and the inner lining tray 1, and the vertical support column 17 provides a reinforcing support for the inner lining tray 1.

[0024] like Figure 1 In this embodiment, the front of the inner lining tray 1 is formed by a crossbeam 3, a longitudinal beam 5, and the four edges of the inner lining tray 1, creating four receiving slots 4. The back of the inner lining tray 1 is embedded with a transverse support rod 8, a longitudinal support rod 9, and four auxiliary longitudinal rods 14. Each additional crossbeam 3 or longitudinal beam 5 adds two more receiving slots 4 to the inner lining tray 1. In other embodiments, the number of receiving slots 4 is not limited to four.

[0025] In this embodiment, the outer frame, horizontal support rods, longitudinal support rods, vertical support columns, and auxiliary longitudinal rods are all made of paper or pulp, and are all biodegradable, which is beneficial to environmental protection. Although the inner lining tray 1 is a paper product or a paper-containing composite product, the paper tray structure of this solution is also applicable to inner lining trays 1 made of other materials with low strength, such as inner lining trays made of biodegradable foamed plastic material.

[0026] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model. Therefore, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
