Description

Technical Field

[0001] This utility model relates to the field of blister packaging technology, specifically a type of blister packaging. Background Technology

[0002] Blister packaging is a common type of plastic packaging container, widely used in the packaging of electronic products, daily consumer goods, medical devices, toys and other fields. It is usually made of thermoplastic plastic sheets through vacuum forming process. It has the advantages of high transparency, good formability, low cost and easy display. Common blister packaging is mostly made by heat sealing or snapping together a lower blister and an upper blister (or cover). The product is fixed in the placement groove of the lower blister, realizing the dual functions of protection and display.

[0003] Existing blister packs mostly rely on the elasticity of the plastic body for cushioning, resulting in a relatively simple structure and poor impact resistance. During transportation or drops, products are easily damaged by vibration or collision. This is especially true for products with precision electronic components or easily scratched surfaces, where existing structures cannot provide sufficient protection. Furthermore, blister packs only use the shape of the placement slot to limit and fix the product, leaving tiny gaps between the packaging and the slot wall. This can cause the product to wobble, leading to wear or loosening during transportation, which affects user experience and product quality. Therefore, we propose a new type of blister pack. Utility Model Content

[0004] The purpose of this utility model is to provide a blister pack to solve the problems mentioned in the background art. Existing blister packs mostly rely on the elasticity of the plastic body for cushioning, have a relatively simple structure, and poor impact resistance. During transportation or drops, products are easily damaged by vibration or collision. Especially for precision electronic components or products with easily scratched surfaces, the existing structure cannot provide sufficient protection. In addition, the blister pack only limits and fixes the product by the shape of the placement groove, and there will be a small gap between the packaging and the groove wall. The product is prone to shaking, resulting in wear or loosening during transportation, which affects user experience and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a blister pack, comprising: a lower blister pack, and an upper blister pack disposed on the upper side of the lower blister pack; It also includes: multiple placement slots are provided on the lower bubble shell, and grooves are provided on both sides of the placement slots on the lower bubble shell. A second airbag is fixedly connected in the groove. A first airbag is fixedly connected to both inner sides of the placement slot. A connecting tube is fixedly connected between the first airbag and the second airbag. The connecting tube passes through the inner side of the lower bubble shell.

[0006] The upper bubble shell has four symmetrically arranged locking blocks on its lower side, and the locking blocks have equidistant limit protrusions at equal intervals around their sides. The lower bubble shell has four symmetrically arranged locking slots on its upper side, which cooperate with the locking blocks and the limit protrusions.

[0007] The upper bubble shell has symmetrically arranged pressing protrusions on both sides of the placement groove, and the pressing protrusions cooperate with the groove.

[0008] The lower bubble shell is provided with a first slot between the two placement slots, and a second slot is provided on one side of the two placement slots.

[0009] The lower bubble shell is provided with a pressing protrusion on the lower side of the placement groove, and a supporting protrusion is provided on the upper side of the pressing protrusion.

[0010] The lower bubble shell has a through hole located at the supporting protrusion.

[0011] The lower bubble shell has an annular protrusion at the bottom of the placement groove, and the bottom surface of the annular protrusion is located below the bottom surface of the pressing protrusion.

[0012] This utility model has at least the following beneficial effects: This invention, through the first airbags installed on the inner walls of both sides of the placement slot and the second airbags connected to the connecting pipe, forms a closed air pressure linkage buffer structure. When the blister pack is subjected to external impact, it can achieve dynamic energy dispersion and absorption, effectively mitigating the impact forces such as vibration and drops during transportation, and enhancing the protection of the internal product. In addition, the first airbag is close to the side wall of the packaged item, and in the closed state, it can wrap the side of the packaged product, eliminating the gap between the product and the placement slot, effectively avoiding scratches or loosening caused by shaking during transportation, and improving the stability and safety of the product. Furthermore, the pre-pressure applied to the second airbag by the pressure protrusion when closed can also enhance the tightness of the fit between the upper and lower blister packs, reduce internal gaps, and improve the overall structural rigidity and dustproof and moisture-proof performance.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figures 1 to 7 This utility model provides a technical solution: a blister pack, comprising: a lower blister pack 1, and an upper blister pack 2 disposed on the upper side of the lower blister pack 1; It also includes: multiple placement slots 3 are provided on the lower blister pack 1, which are used to accommodate the packaged product. The shape and size of the placement slots 3 are customized according to the shape of the packaged product to ensure stable embedding of the product; grooves 7 are provided on both sides of the placement slots 3 on the lower blister pack 1, and second airbags 8 are fixedly connected in the grooves 7; first airbags 6 are fixedly connected to both inner sides of the placement slots 3. The first airbags 6 and the second airbags 8 are made of flexible material, with good resilience and sealing performance. The first airbags 6 are close to the side wall of the placement slots 3, and are used to directly contact and wrap the side of the packaged product to achieve local buffering and limiting; a connecting tube 9 is fixedly connected between the first airbags 6 and the second airbags 8. The connecting tube 9 passes through the inner side of the lower blister pack 1 to achieve a concealed arrangement of the airflow channel and avoid exposure damage.

[0017] Four locking blocks 5 are symmetrically arranged on the lower side of the upper blister 2. Limiting protrusions 11 are evenly spaced around the side of the locking blocks 5. Four locking slots 4 are symmetrically arranged on the upper side of the lower blister 1. The locking slots 4 cooperate with the locking blocks 5 and the limiting protrusions 11. The positions of the four locking blocks 5 correspond one-to-one with the positions of the four locking slots 4. The limiting protrusions 11 are evenly distributed around the circumference of the locking blocks 5 and are serrated or hemispherical protrusions. After being inserted into the locking slots 4, an interference fit can be generated, realizing the rapid assembly of the upper blister 2 and the lower blister 1 and enhancing the overall structural stability.

[0018] Symmetrical pressure protrusions 10 are provided on both sides of the upper blister pack 2 and on both sides of the placement groove 3. The pressure protrusions 10 cooperate with the grooves 7. When the upper blister pack 2 and the lower blister pack 1 are assembled and closed, the locking block 5 will engage with the locking groove 4, and the pressure protrusions 10 will be pressed into the grooves 7, pressing against the second airbag 8. This allows the gas in the second airbag 8 to enter the first airbag 6 through the connecting pipe 9, causing the first airbag 6 to inflate and press against the surface of the product placed in the placement groove 3, filling the gap between the packaged product and the inner wall of the placement groove 3, thus providing a covering effect for the product and improving the product packaging. The stability of the blister pack is such that when the blister pack is subjected to external impacts (such as drops or compression), the energy can be dispersed and absorbed through the first airbag 6, effectively mitigating the impact forces such as vibration and drops during transportation, enhancing the protection of the internal products, improving the overall impact resistance, effectively preventing scratches, wear or loosening caused by shaking during transportation, improving the stability and safety of the products, and the pressure of the pressure protrusion 10 against the second airbag 8 can also enhance the tightness of the fit between the upper blister pack 2 and the lower blister pack 1, reduce internal gaps, help form an overall sealed environment, and improve dustproof and moisture-proof performance.

[0019] The lower blister pack 1 is provided with a first slot 12 between the two placement slots 3, and a second slot 13 is provided on one side of the two placement slots 3. The second slot 13 is located on the outer edge of the outer placement slot 3, which makes it easier for manual or robotic arms to grasp the edge of the blister pack, improving the convenience of operation. When the upper blister pack 2 is opened and the packaged product in the placement slot 3 is taken out, the pressure protrusion 10 no longer presses against the second airbag 8, so that the first airbag 6 no longer presses against the surface of the packaged product. The arrangement of the first slot 12 and the second slot 13 also makes it easy to take out the packaged product.

[0020] Example 2 The lower blister pack 1 is located on the lower side of the placement groove 3 and is provided with a pressing protrusion 14. The pressing protrusion 14 is an arc-shaped structure that protrudes downward from the bottom surface of the lower blister pack 1 and can be pressed with a finger. The upper side of the pressing protrusion 14 is provided with a supporting protrusion 15. The supporting protrusion 15 is a spherical shape that bulges upward, or it can be a small dome or column that bulges upward, corresponding to the pressing protrusion 14. By pressing the pressing protrusion 14 upward, its deformation causes the supporting protrusion 15 to be pushed upward, thereby pushing the packaged item upward, which can further assist and facilitate the removal of the packaged item.

[0021] The lower blister pack 1 has a through hole 16 at the support protrusion 15. When the support protrusion 14 is pressed, the support protrusion 15 can lift the packaged item through the through hole 16. At the same time, the through hole 16 can also serve as a mold exhaust channel, which helps to expel gas during the vacuum forming process and improves the molding yield.

[0022] The lower blister pack 1 is provided with an annular protrusion 17 at the bottom of the placement groove 3. The bottom surface of the annular protrusion 17 is located below the bottom surface of the pressing protrusion 14. The annular protrusion 17 is arranged around the bottom periphery of the placement groove 3, and its lower surface is lower than the lowest point of the pressing protrusion 14. When the blister pack is placed on a support surface such as a table, the annular protrusion 17 contacts the support surface first, effectively protecting the pressing protrusion 14 from friction or squeezing damage from the support surface. In addition, the annular protrusion 17 can also enhance the structural rigidity of the bottom of the placement groove 3, prevent deformation due to excessive local stress, improve overall durability, and improve placement stability.
