Description

Technical Field

[0001] This utility model relates to the field of blister tray structure technology, and in particular to a blister tray that is easy to stack. Background Technology

[0002] Blister trays, also known as plastic trays, are made by forming a specific groove in a rigid plastic sheet using a thermoforming process. Products are placed inside the groove, serving to protect and enhance their appearance. There are also transport trays. Trays are commonly used for convenience. There are many types of blister trays, and tray products are one type of blister packaging in the industry. These trays have strong load-bearing capacity. The appropriate tray size is designed based on the shape, structure, and weight of the item to withstand the load. The thickness of the material used also varies, depending on the packaging requirements of the item.

[0003] Traditional blister trays are typically designed with a flat structure. While they perform well when carrying goods, they are prone to instability when stacked, especially in multi-level stacks. The lack of locking mechanisms between stacked trays makes them susceptible to tilting or collapse, increasing safety hazards during warehousing and transportation. Therefore, a stackable blister tray is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stackable blister tray includes a blister tray component. The blister tray component includes a plastic inner tray. Two side panels are symmetrically connected to the left and right sides of the plastic inner tray. An inner buckle strip is connected to the inner side of the side panel. An extension member is connected to the top of the side panel. The extension member includes a plastic sealing plate that is fixed to the side panel. The side of the plastic sealing plate has a slot that matches the inner buckle strip.

[0007] Preferably, thickened protrusions are provided at the four corners of the inner wall of the plastic inner tray. Providing thickened protrusions at the corners of the inner wall of the plastic inner tray can effectively prevent the plastic inner tray from being worn and leaked due to bumps at the corners.

[0008] Preferably, the plastic inner tray has an inwardly inclined design on the left and right sides, and the top of the inner wall of the plastic inner tray has concave surfaces on both sides. The inner groove on the side of the plastic inner tray provides a space for inserting another plastic inner tray.

[0009] Preferably, an inner partition is connected to the center of the inner wall of the plastic inner tray, and a positioning groove adapted to the inner partition is opened at the bottom of the plastic inner tray. The positioning groove of the plastic inner tray can cooperate with the inner partition to quickly position and overlap the two plastic inner trays.

[0010] Preferably, the inner partition has arc-shaped grooves on both sides, and the positioning groove of the plastic inner support has two symmetrically arranged protruding ends on both sides. The protruding ends in the positioning groove of the plastic inner support can be constrained and fixed to a certain extent by the inner partition inserted at the bottom.

[0011] Preferably, the top of the inner wall of the plastic inner support is provided with two inner ribs, and the bottom end face of the plastic inner support is provided with a lower rib. By providing inner ribs at the top of the inner wall of the plastic inner support, the inner wall of the plastic inner support is reinforced, effectively preventing deformation of the plastic inner support during use.

[0012] Preferably, the bottom end of the plastic sealing plate has a through groove, and an inner lining plate is provided in the through groove. The two sides of the inner lining plate are concave and relatively thin, which makes it easy to cut the periphery of the inner lining plate with a knife, so as to cut the inner lining plate according to the needs.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting the inner buckle strip and the plastic sealing plate, the edge locking of the upper and lower blister trays is achieved. Compared with the traditional structure, this device stacks the upper and lower blister trays, so that the plastic sealing plate on one blister tray is inserted into the side hanging plate of the other blister tray. The inner buckle strip on the inner side of the side hanging plate engages with the slot on the side of the plastic sealing plate, thereby completing the edge locking, ensuring the stacking and fixation of the blister trays, and effectively reducing the tilting or collapse of the blister trays in multi-layer stacking.

[0015] 2. By setting an inner partition, the positioning of the blister tray components when stacked can be achieved. By directly stacking two blister tray components, one inner partition is inserted into the groove at the bottom of the other plastic inner tray. Through the cooperation between the groove and the inner partition, the two plastic inner trays can be positioned and prevented from sliding or shifting when stacked. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4 A stackable blister tray includes a blister tray component 1, which includes a plastic inner tray 11. Two side panels 14 are symmetrically connected to the left and right sides of the plastic inner tray 11. An inner buckle strip 2 is connected to the inner side of the side panel 14. An extension 3 is connected to the top of the side panel 14. The extension 3 includes a plastic sealing plate 31 that is fixed to the side panel 14. The plastic sealing plate 31 has a slot on its side that is adapted to the inner buckle strip 2.

[0024] Thickened protrusions are provided at the four corners of the inner wall of the plastic inner support 11.

[0025] The plastic inner support 11 has an inward-sloping design on both sides, and the top of the inner wall of the plastic inner support 11 has concave surfaces on both sides.

[0026] An inner partition 4 is connected to the center of the inner wall of the plastic inner support 11, and a positioning groove adapted to the inner partition 4 is opened at the bottom of the plastic inner support 11.

[0027] The inner partition 4 has arc-shaped grooves on both sides, and the inner wall of the positioning groove of the plastic inner support 11 has two symmetrical protrusions on both sides.

[0028] The plastic inner support 11 has two inner ribs 12 at the top of its inner wall and a lower rib 13 at its bottom.

[0029] The bottom end of the plastic sealing plate 31 has a through groove, and an inner lining plate 32 is provided inside the through groove.

[0030] Thickened protrusions are provided at the corners of the inner wall of the plastic inner tray 11 to effectively prevent the plastic inner tray 11 from being worn and leaked due to bumps at the corners. When two plastic inner trays 11 are stacked, the inner groove on the side of the plastic inner tray 11 provides a space for the other plastic inner tray 11 to be inserted, thereby achieving the constraint and positioning of the stacked plastic inner trays 11.

[0031] When two plastic inner trays 11 are stacked, the positioning groove of the plastic inner tray 11 can cooperate with the inner partition 4, thereby quickly positioning and aligning the two plastic inner trays 11 to ensure the stacking effect. When the inner partition 4 is inserted into the positioning groove at the bottom of another plastic inner tray 11, the protrusion end in the positioning groove of the plastic inner tray 11 can be constrained and fixed to a certain extent by the inner partition 4 inserted at the bottom.

[0032] By setting inner ribs 12 at the top of the inner wall of the plastic inner tray 11, the inner wall of the plastic inner tray 11 is reinforced, effectively preventing deformation of the plastic inner tray 11 during use and improving the lifting and support effect. At the same time, the bottom of the plastic inner tray 11 is provided with cross-designed lower ribs 13, which effectively reduces the probability of wear and tear at the bottom of the plastic inner tray 11. In the processing of the blister tray 1, an integrated molding design is adopted. The inner lining plate 32 has concave sides and a relatively thin thickness, which makes it easy to cut the periphery of the inner lining plate 32 with a cutting tool. This allows the inner lining plate 32 to be cut according to the requirements, which in turn facilitates the lifting of the plastic sealing plate 31 in actual use.

[0033] Working principle: According to the appendix Figure 2 With appendix Figure 3 As shown, when the blister tray pieces 1 are stacked, the upper and lower blister tray pieces 1 overlap. At this time, the inner partition 4 of the lower blister tray piece 1 is inserted into the slot of the inner partition 4 of the upper blister tray piece 1. After positioning the two blister tray pieces 1, the two sides of the two blister tray pieces 1 can be pressed down, so that the inner buckle strip 2 can be snapped back into the slot on the outside of the plastic sealing plate 31 at the top of the other blister tray piece 1, thereby achieving locking and fixing at the edge of the stacked blister tray pieces 1.

[0034] Secondly, according to the appendix Figure 3 With appendix Figure 4 As shown, during use, the plastic sealing plate 31 has an inner lining plate 32 inside. The inner lining plate 32 is a thin layer design. According to the usage requirements, the periphery of the inner lining plate 32 can be cut to form a handle end design.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
