Description

Technical Field

[0001] The present invention belongs to the technical field of packaging, and specifically relates to a plastic blister tray with a high-strength support structure. Background Art

[0002] A plastic blister tray is a plastic tray manufactured by a blister process. The blister process forms a container with a specific shape and structure by vacuum-sucking a heated plastic sheet. Plastic blister trays are usually used for product storage, transportation, and display.

[0003] In the prior art, plastic blister trays are integrally formed by the blister method. Limited by the forming material of the plastic suction cup, the self-strength of the blister tray after actual forming is generally low. When subjected to extrusion and collision, the tray itself deforms severely, and its actual support and storage capacity is poor, resulting in poor use effects.

[0004] In addition, when storing and placing objects, for the storage of products, the actual stability is poor. Under vibration or shaking, the products will vibrate accordingly, and the actual storage effect is poor, which is particularly obvious during transportation, resulting in poor comprehensive use effects. Summary of the Invention

[0005] The purpose of the present invention is to provide a plastic blister tray with a high-strength support structure to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A plastic blister tray with a high-strength support structure, including a tray body. A strengthening component is fixedly provided at the bottom of the tray body. A placement groove is opened at the top of the tray body. A protrusion is provided at the bottom of the tray body. The placement groove is opened in the protrusion. The bottom of the protrusion is fixedly connected to an elastic bottom frame. The elastic bottom frame communicates with the placement groove. An auxiliary frame is fixedly provided at the bottom of the strengthening component. The auxiliary frame is sleeved outside the protrusion.

[0007] Preferably, the strengthening component includes a strengthening frame and an adaptation opening. The adaptation opening is opened on the front of the strengthening frame and corresponds to the protrusion one by one. The adaptation opening is sleeved outside the protrusion. The strengthening frame is fixedly connected to the bottom surface of the tray body.

[0008] Preferably, the auxiliary frame is fixed to the bottom surface of the strengthening frame and corresponds to the adaptation opening one by one, and is sleeved outside the protrusion. An opening is provided on the outer side surface of the auxiliary frame.

[0009] Preferably, the strengthening component further includes a sleeve. The sleeve is fixedly nested in the strengthening frame. The upper end of the sleeve is fixedly sleeved in the tray body. A sleeve hole is opened on the front of the tray body. The sleeve is fixedly sleeved in the sleeve hole.

[0010] Preferably, a conduction groove is formed in the top surface of the tray body. The conduction groove is communicated with the sleeve, and a reserved groove is formed in the top of the tray body. The conduction groove is communicated with the placement groove through the reserved groove.

[0011] Preferably, the reserved groove is an arc groove, and the reserved grooves are symmetrically arranged on both sides of the top of the placement groove.

[0012] Preferably, a bottom opening is formed at the bottom of the protrusion. The upper end of the bottom opening is communicated with the placement groove, and the lower end is communicated with the elastic bottom frame.

[0013] Preferably, a corrugated structure is arranged in the middle of the elastic bottom frame, and the elastic bottom frame is elastically compressed through the corrugated structure.

[0014] Preferably, positioning holes are formed in the top of the tray body, and positioning foot posts are fixedly arranged at the bottom of the tray body. The positioning foot posts correspond to the positioning holes one by one, and the sizes of the positioning foot posts and the positioning holes are matched.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) By previously fixing the auxiliary frame to the bottom surface of the reinforcement frame, the auxiliary frame is sleeved outside the protrusion after pasting, so as to complete the reinforcement protection. The overall strength of the tray is increased. Both the reinforcement frame and the auxiliary frame are made of carbon fiber, which has strong structural strength, improves the support strength, and has a light texture, reducing the impact on the quality of the blister tray itself, and realizing high-strength support.

[0017] (2) By fixedly nesting the sleeve with the reinforcement frame and cooperating with the sleeve holes formed in the top of the tray body, the reinforcement frame is more firmly fixed to the bottom of the tray body through the sleeve, further improving the connection stability between the tray body and the added high-strength support structure.

[0018] (3) By cooperating with the conduction groove and the reserved groove on the top of the tray body, and cooperating with the sleeve and the conduction groove that are communicated with each other, the sleeve is communicated with the placement groove. When the top of the tray body is sealed, the air in the placement groove inside the tray body can also be conducted through the sleeve during transportation. For items that need to be transported ventilated, the storage and transportation effect is improved. And when actually taking and placing products from the placement groove, the space for fingers is reserved through the reserved grooves on both sides, and the internal products can be conveniently held directly along both sides of the placement groove.

[0019] (4) In the present invention, when the product is placed in the placement groove and during transportation or placement, under the action of the weight of the product, the tray body presses down the elastic bottom frame, causing the heat preservation structure to be compressed. When vibration occurs, the elastic bottom frame buffers the vibration potential energy to complete the buffering protection. In addition, when the bottom surface of the placed product is flat and its own mass is small, when it is placed in the placement groove, it first actively compresses the elastic bottom frame, then presses the product in the placement groove, and seals the top of the bottom opening, making the inside of the elastic bottom frame closed. Under the elastic restoration effect of the elastic bottom frame, a negative pressure state is presented inside, and the negative pressure state is further used to adsorb and sleeve the product in the placement groove, improving the placement stability.

[0020] (5) In the present invention, the positioning foot columns on the bottom surface of the upper tray body are inserted downward into the positioning holes on the top surface of the lower tray body to complete the one-to-one positioning socket connection and stacking. At the same time, the elastic bottom frame on the bottom surface of the upper tray body is elastically compressed inside the lower tray body and presses tightly on the top surface of the product in the placement groove, completing the auxiliary pressing and positioning of the product during stacking, improving the stability of the product placement during stacking, and the elastic pressing state also buffers the vibration of the product.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 7 shown, an embodiment of the present invention provides a plastic thermoformed tray with a high-strength support structure, including a tray body 1. A reinforcing component 5 is fixedly provided at the bottom of the tray body 1. A placement groove 2 is formed at the top of the tray body 1. A protrusion 12 is provided at the bottom of the tray body 1. The placement groove 2 is formed in the protrusion 12. The bottom of the protrusion 12 is fixedly connected to an elastic bottom frame 7. The elastic bottom frame 7 communicates with the placement groove 2. An auxiliary frame 6 is fixedly provided at the bottom of the reinforcing component 5. The auxiliary frame 6 is sleeved outside the protrusion. The reinforcing component 5 includes a reinforcing frame 51 and an adaptation opening 52. The adaptation opening 52 is formed on the front surface of the reinforcing frame 51 and corresponds to the protrusion 12 one by one. The adaptation opening 52 is sleeved outside the protrusion 12. The reinforcing frame 51 is fixedly connected to the bottom surface of the tray body 1. The auxiliary frame 6 is fixed to the bottom surface of the reinforcing frame 51 and corresponds to the adaptation opening 52 one by one and is sleeved outside the protrusion 12. An opening is provided on the outer side surface of the auxiliary frame 6.

[0031] Embodiment 1: After the tray body 1 is thermoformed, the reinforcing component 5 is adsorbed and fixed on the bottom surface of the tray body 1. By previously fixing the auxiliary frame 6 to the bottom surface of the reinforcing frame 51, the auxiliary frame 6 is sleeved outside the protrusion 12 after pasting, completing the reinforcement protection and increasing the overall strength of the tray.

[0032] Both the reinforcing frame 51 and the auxiliary frame 6 are made of carbon fiber, having strong structural strength, improving the support strength, and being light in texture, reducing the impact on the quality of the thermoformed tray itself.

[0033] Among them, the reinforcing component 5 further includes a sleeve 53. The sleeve 53 is fixedly nested in the reinforcing frame 51. The upper end of the sleeve 53 is fixedly sleeved in the tray body 1. A sleeve hole 4 is formed on the front surface of the tray body 1. The sleeve 53 is fixedly sleeved in the sleeve hole 4.

[0034] Embodiment 2: The sleeve 53 is fixedly nested with the reinforcing frame 51 and cooperates with the sleeve hole 4 formed at the top of the tray body 1, so that the reinforcing frame 51 is more firmly fixed to the bottom of the tray body 1 through the sleeve 53, improving the connection stability between the tray body 1 and the added high-strength support structure.

[0035] Among them, a conduction groove 9 is formed on the top surface of the tray body 1. The conduction groove 9 communicates with the sleeve 53. A reserved groove 8 is formed at the top of the tray body 1. The conduction groove 9 communicates with the placement groove 2 through the reserved groove 8. The reserved groove 8 is an arc-shaped groove, and the reserved grooves 8 are symmetrically arranged on both sides of the top of the placement groove 2.

[0036] Embodiment 3: By cooperating with the conduction groove 9 and the reserved groove 8 on the top of the tray body 1, and by cooperating with the sleeve 53 and the conduction groove 9 that communicate with each other, the sleeve 53 and the placement groove 2 are communicated. When the top of the tray body 1 is sealed, during transportation, the air conduction of the placement groove 2 inside the tray body 1 can also be maintained through the sleeve 53. For objects that need to be transported with ventilation, the storage and transportation effect is improved. Moreover, when actually taking and placing products in the placement groove 2, the space for fingers is reserved through the reserved grooves 8 on both sides, and the internal products can be conveniently held directly along both sides of the placement groove 2.

[0037] Among them, a bottom port 3 is formed at the bottom of the protrusion 12. The upper end of the bottom port 3 communicates with the placement groove 2, and the lower end communicates with the elastic bottom frame 7. A corrugated structure is provided in the middle of the elastic bottom frame 7, and the elastic bottom frame 7 is elastically compressed through the corrugated structure.

[0038] Embodiment 4: When the product is placed in the placement groove 2 and during transportation or placement, due to the weight of the product, the tray body 1 compresses the elastic bottom frame 7 downward, causing the heat preservation structure to be compressed. When vibration occurs, the elastic bottom frame 7 buffers the vibration potential energy to complete the buffer protection. In addition, when the bottom surface of the placed product is flat and its own mass is small, when it is placed in the placement groove 2, the elastic bottom frame 7 is actively compressed first, and then the product is pressed into the placement groove 2 and the top of the bottom port 3 is sealed, making the inside of the elastic bottom frame 7 closed. Under the elastic recovery effect of the elastic bottom frame 7, a negative pressure state is presented inside, and the negative pressure state is further used to adsorb and sleeve the product in the placement groove 2 to improve the placement stability.

[0039] Among them, positioning holes 10 are formed at the top of the tray body 1. Positioning foot columns 11 are fixedly provided at the bottom of the tray body 1. The positioning foot columns 11 correspond to the positioning holes 10 one by one, and the sizes of the positioning foot columns 11 and the positioning holes 10 match each other.

[0040] Embodiment 5: When pallet stacking is required, the positioning foot columns 11 on the bottom surface of the upper tray body 1 are inserted downward into the positioning holes 10 on the top surface of the lower tray body 1 to complete one-to-one positioning and sleeving, and complete the stacking. At the same time, the elastic bottom frame 7 on the bottom surface of the upper tray body 1 is elastically compressed inside the lower tray body 1 and presses tightly on the top surface of the product in the placement groove 2, completing the auxiliary pressing and positioning of the product during stacking, improving the placement stability of the product during stacking, and the elastic pressing state also buffers the vibration of the product.
