Description

Technical Field

[0001] This utility model relates to the field of blister pack technology, and in particular to a reinforced connecting edge structure for a blister pack. Background Technology

[0002] Blister boxes, as lightweight, transparent, and low-cost packaging containers, are widely used in electronic components, medical devices, cosmetics, food, and many other fields. Blister forming is a plastic processing technique. The main principle is to heat a flat, rigid plastic sheet until it softens, then vacuum-form it onto a mold surface, where it cools and solidifies. For example, blister packaging boxes save on raw materials, are lightweight, easy to transport, and meet environmental protection and green packaging requirements. By designing corresponding placement slots inside, they can package any irregularly shaped product, eliminating the need for additional cushioning materials. The packaged products are transparent and visible, aesthetically pleasing, easy to sell, and suitable for mechanized and automated packaging, facilitating modern management.

[0003] In existing technologies, the connection strength of the connecting edges of some blister packs is insufficient. After long-term opening and closing, the buckles are prone to wear and loosening, and the lid may even separate from the base. In addition, the operation is cumbersome. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low connection strength and easy opening and closing in the existing technology, and to propose a reinforced connection edge structure for a blister folding box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced connecting edge structure for a blister folding box, comprising a base, a top cover, and a connector.

[0006] The base and the top cover are hinged together. The base has a placement area inside. A lower ring is fixedly connected to the top edge of the base. The top cover has a fixing area inside. A top ring is provided at the top edge of the top cover.

[0007] The connector includes an upper connecting block and a lower connecting block. The upper connecting block is fixedly connected to the surface of the upper cover, and the lower connecting block is fixedly connected to the surface of the base. The lower connecting block and the upper connecting block are interlocked by a spring assembly. The surface of the lower connecting block is provided with a connecting groove, and the spring assembly is fixedly connected to the connecting groove.

[0008] Furthermore, the spring assembly includes a fixing plate, which is fixedly connected to the inner wall of the connecting groove.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a reinforced connecting edge structure for a blister folding box, including a base 1, a top cover 2, and a connector 3.

[0024] The base 1 and the top cover 2 are hinged together. The base 1 has a placement area 11 inside. The bottom ring 12 is fixedly connected to the top edge of the base 1. The top cover 2 has a fixing area 21 inside. The top ring 22 is provided at the top edge of the top of the top cover 2.

[0025] The specific settings and functions of connector 3 will be explained below.

[0026] In this embodiment: the connector 3 includes an upper connecting block 31 and a lower connecting block 32. The upper connecting block 31 is fixedly connected to the surface of the upper cover 2, and the lower connecting block 32 is fixedly connected to the surface of the base 1. The lower connecting block 32 and the upper connecting block 31 are interlocked by a spring assembly 33. The surface of the lower connecting block 32 is provided with a connecting groove, and the spring assembly 33 is fixedly connected to the connecting groove.

[0027] The effect achieved by the above components is that the lower connecting block 32 and the upper connecting block 31 are elastically engaged through the spring assembly 33. When the folding box is closed, the elastic force provided by the spring assembly 33 makes the two tightly connected, which enhances the stability of the connecting edge.

[0028] Specifically, the spring assembly 33 includes a fixing plate 331, which is fixedly connected to the inner wall of the connecting groove. Both sides of the fixing plate 331 are fixedly connected to a telescopic spring 332. The end of the telescopic spring 332 away from the fixing plate 331 is fixedly connected to a limiting block 333. The end of the limiting block 333 away from the telescopic spring 332 is fixedly connected to a connecting rod 334. The connecting rod 334 is connected through the inner wall of the lower connecting block 32.

[0029] The effects achieved by the above components are as follows: the fixed plate 331 provides stable support for the telescopic spring 332, ensuring the overall structure of the spring assembly 33 is stable; the telescopic spring 332 extends and retracts when subjected to force, driving the limit block 333 to move, realizing the engagement and disengagement with the upper connecting block 31. It is symmetrically distributed on both sides of the fixed plate 331, ensuring that the limit block 333 is subjected to uniform force and the engagement process is smooth and reliable.

[0030] Specifically, a pressing head 335 is fixedly connected to one end of the limiting block 333 of the connecting rod 334, and the telescopic springs 332 are symmetrically distributed on both sides of the fixed plate 331.

[0031] The effect achieved by the above components is as follows: the pressing head 335 is convenient for users to operate. When it is necessary to open the folding box, the user only needs to press the pressing head 335. The pressing head 335 pushes the limiting block 333 to compress the telescopic spring 332 through the connecting rod 334, so that the limiting block 333 is disengaged from the upper connecting block 31. The operation is simple and convenient.

[0032] Specifically, a first rectangular groove 311 is provided in the middle of the surface of the upper connecting block 31, and a second rectangular groove 312 is provided on both sides of the first rectangular groove 311.

[0033] The effects achieved by the above components are as follows: the first rectangular groove 311 is used to cooperate with the limiting block 333 to achieve a snap-fit, limiting the relative displacement of the upper cover 2 and the base 1 in the horizontal direction and enhancing the connection strength; the second rectangular groove 312 provides clearance space for the limiting block 333 during the extension and retraction process to avoid interference, and on the other hand, when the folding box is subjected to a large external force impact, the second rectangular groove 312 can disperse the stress and prevent the upper connecting block 31 from being damaged due to stress concentration.

[0034] Specifically, the limiting block 333 passes through the first rectangular groove 311 and engages with the upper connecting block 31.

[0035] The effect achieved by the above components is as follows: by engaging the limiting block 333 with the first rectangular groove 311, the upper cover 2 and the base 1 are locked at the connecting edge, which restricts the relative movement of the two in the opening and closing direction, ensures the stability of the folded box in the closed state, and prevents the lid from being opened accidentally.

[0036] Specifically, the lower ring 12 has a snap-fit ​​groove 13 on its side, and the upper ring 22 has a snap-fit ​​block 23 on its side, and the snap-fit ​​groove 13 snaps into each other.

[0037] Specifically, the locking slot 13 and the locking block 23 are interlocked.

[0038] The aforementioned components achieve the following effects: the engagement of the locking groove 13 and the locking block 23, based on the main connection achieved by the connector 3, further enhances the sealing and stability of the folding box edge. When the folding box is closed, the locking block 23 is embedded in the locking groove 13, fitting tightly to prevent external contaminants such as dust and moisture from entering the placement area 11. At the same time, it provides additional fastening force to the folding box in the vertical direction, preventing relative displacement between the top cover 2 and the base 1 during use.

[0039] Working principle: When the blister pack needs to be closed, the upper cover 2 and the base 1 are initially fixed at the connection edge by the snap-fit ​​groove 13 and the snap-fit ​​block 23. At this time, the upper connecting block 31 and the lower connecting block 32 are close together. The operator presses the pressing head 335 with his finger. The pressing head 335 drives the connecting rod 334 to move, which in turn pushes the limiting block 333 to compress the telescopic spring 332, so that the limiting block 333 snaps into the first rectangular groove 311. After the snap-fit ​​is completed, the pressing head 335 is released, so that the limiting block 333 slides into the second rectangular groove 312 to complete the fixation. When the blister pack is opened, the pressing head 335 is pressed to move the limiting block 333 from the second rectangular groove 312 to the first rectangular groove 311, so that the limiting block 333 is disengaged from the upper connecting block 31, and then the pressing head 335 is released.
