Description

Technical Field

[0001] This utility model relates to the field of blister tray technology, and in particular to a buffer layer combined blister tray. Background Technology

[0002] A blister tray is a disc-shaped plastic part formed by a blister forming process. It is commonly used for packaging, fixing and protecting various items. It achieves protection and efficient transportation of items through cushioning, preventing shaking or collision during transportation. Therefore, a type of blister tray with a cushioning layer is used.

[0003] To address this, patent CN221954844U discloses a combined blister tray, including a connecting tray with a buffer frame connected to its lower end. Buffer components are evenly connected to both sides of the lower end of the inner wall of the buffer frame. This combined blister tray, through the cooperation of connecting blocks, rotating rods, sliders, sliding rods, fixing blocks, buffer springs, and buffer plates, allows for convenient compression and fixation of objects via the lower end of the buffer plate. Simultaneously, the buffer plate cushions the objects inside the connecting tray, improving the stability of the objects within the connecting tray and thus enhancing the overall stability of the blister tray. Furthermore, through the cooperation of the frame, moving rods, locking blocks, connecting springs, pushing blocks, mounting blocks, housing, and slots, stacked blister trays can be secured, allowing for better stacking and preventing collapse during stacking, thus improving the stability of the stacked blister trays.

[0004] While the aforementioned modular blister packs can prevent collapse when stacked and improve the stability of the stacked blister packs, their limited applicability makes them unsuitable for use because they are not easy to limit and cannot prevent items from sliding or colliding inside the blister packs due to bumps and flips during transportation. Utility Model Content

[0005] The purpose of this invention is to provide a buffer layer combined blister tray to solve the defect of existing buffer layer combined blister trays that are inconvenient for positioning.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a buffer layer combined blister tray, including a tray body and a placement cavity;

[0007] The top of the disc body is evenly provided with placement cavities, and each placement cavity is provided with a buffer structure inside;

[0008] Positioning structures are evenly provided on both sides of the disk body;

[0009] The bottom end of the disc is uniformly provided with a limiting structure. The limiting structure includes limiting grooves uniformly opened at the bottom end of the disc. Each limiting groove is provided with a buffer pad. Both sides of the top of the buffer pad inside the disc are provided with a sliding groove. Each sliding groove is provided with a rubber pad.

[0010] When using this device, the limiting structure facilitates its anti-bump function, thereby improving the applicability of the buffer layer combination blister tray during use; the buffer structure facilitates its anti-displacement function, thereby improving the stability of the buffer layer combination blister tray during use; and the positioning structure facilitates its assembly function, thereby improving the convenience of using the buffer layer combination blister tray.

[0011] Preferably, the cushioning structure includes EVA foam, pearl cotton, and pre-drilled grooves. The EVA foam is disposed inside the placement cavity, and pearl cotton is placed inside each EVA foam. Pre-drilled grooves are formed on both sides of the EVA foam. The EVA foam absorbs bumps generated during transportation and firmly secures the item, preventing it from shifting. The pearl cotton, placed over the outside of the item, helps the EVA foam disperse residual pressure, further attenuating vibrations.

[0012] Preferably, one side of the reserved groove extends into the interior of the tray. The pearl cotton can protect items from damage during transportation or storage through its cushioning, vibration damping, and heat insulation properties. The reserved groove also facilitates the retrieval of the pearl cotton and the items.

[0013] Preferably, the positioning structure includes a positioning seat, a groove, and a positioning slot. The positioning seat is evenly fixed to both sides of the bottom end of the disc body, the positioning slots are evenly formed on both sides of the top end of the disc body, and the grooves are formed on both sides of the bottom end of the disc body. By moving the disc body through the grooves, the friction between the fingers and the disc body is increased under the action of the anti-slip strip, thereby facilitating the handling of the disc body.

[0014] Preferably, the positioning seat and the disc body form a sliding structure through a positioning groove, and anti-slip strips are uniformly fixed to the top of the groove. By moving the positioning seat into the interior of the positioning groove, when the bottom end of the positioning seat abuts against the inner wall of the disc body, it is convenient to combine the two sets of disc bodies, which can effectively prevent the two sets of disc bodies from shifting or misaligning.

[0015] Preferably, the buffer pad has an internal cavity, and the centerline of the buffer pad and the centerline of the placement cavity are collinear. Under the action of the rubber pad and the sliding groove, the buffer pad moves into the interior of the limiting groove. When the discs are assembled, the buffer pad will press against the top of the item.

[0016] Preferably, the main cross-section of the slide groove is T-shaped, and the rubber pad and the disc body form a sliding structure through the slide groove. Under the action of the cavity, the buffer pad deforms, and at this time, the bottom end of the buffer pad always abuts against the top end of the item. Under the action of the buffer pad, the item is prevented from shifting due to vibration and impact during transportation, ensuring continuous restraint of the item, and at the same time absorbing impact and protecting the item.

[0017] The advantages of the buffer layer combined blister tray provided by this utility model are as follows:

[0018] By setting a limiting structure, the buffer pad moves into the limiting groove under the action of the rubber pad and the sliding groove. When the tray is assembled, the buffer pad will press on the top of the item. Under the action of the cavity, the buffer pad will deform. At this time, the bottom of the buffer pad will always be in contact with the top of the item. Under the action of the buffer pad, the item is prevented from shifting due to vibration and impact during transportation, ensuring continuous restraint of the item. At the same time, it can absorb impact and protect the item. This device realizes the function of easy anti-bumping, thereby improving the applicability of the buffer layer combination blister tray in use.

[0019] With its cushioning structure, the EVA foam absorbs bumps during transport and securely holds items in place, preventing them from shifting. Pearl cotton, placed over the outside of the items, helps the EVA foam distribute residual pressure and further dampens vibrations. Through cushioning, vibration damping, and heat insulation, the device protects items from damage during transport or storage. The pre-drilled grooves facilitate the retrieval of the pearl cotton and items, enabling the device to prevent displacement and thus improving the stability of the combined cushioning layer blister pack during use.

[0020] By incorporating a positioning structure and moving the disc via a groove, the friction between fingers and the disc is increased by the anti-slip strips, facilitating the handling of the disc. By moving the positioning seat into the positioning groove, when the bottom of the positioning seat abuts against the inner wall of the disc, it is easy to combine the two sets of discs, effectively preventing displacement or misalignment of the two sets of discs. This achieves the function of easy assembly of the device, thereby improving the convenience of using the buffer layer combination blister tray. Attached Figure Description

The center line of the buffer pad 501 and the center line of the placement cavity 2 are collinear. The main view section of the sliding groove 503 is T-shaped. The rubber pad 502 and the disc body 1 form a sliding structure through the sliding groove 503.

[0033] Reference Figure 1 and Figure 3 As shown, the buffer pad 501 is moved so that one end of the rubber pad 502 abuts against one end of the slide groove 503. The buffer pad 501 is moved so that the rubber pad 502 moves into the interior of the slide groove 503. At this time, the buffer pad 501 moves into the interior of the limiting groove 504. When the disc body 1 is assembled, the buffer pad 501 will press against the top of the item. Under the action of the cavity, the buffer pad 501 will deform. At this time, the bottom end of the buffer pad 501 always abuts against the top of the item. Under the action of the buffer pad 501, the item is prevented from shifting due to vibration and impact during transportation, ensuring continuous restraint of the item, and absorbing impact to protect the item.
