Description

Technical Field

[0001] The invention relates to the field of blister products, in particular to a blister tray for both front and back uses. Background Art

[0002] Blister trays are also called blister trays or plastic trays. They use the blister process to make plastic sheets into plastic with specific grooves, and place the products in the grooves to protect and beautify the products. There are also transport-type pallet packaging. The use of pallets is mostly for convenience. Blister trays are widely used in the electronics industry, toy industry, stationery industry, technology product industry, cosmetics industry, health care product industry, etc.

[0003] For example, a blister tray with both positive and negative uses disclosed in the authorization announcement number CN108945691B includes a plurality of receiving grooves directly pressed and formed on the front side of the tray body, the receiving grooves are arranged in a rectangular array, each receiving groove is connected side by side with acupuncture points directly pressed and formed on the front side of the tray body, and a limiting cavity directly pressed and formed on the front side of the tray body is arranged between two adjacent acupuncture points, the cross-sectional area of ​​the limiting cavity is smaller than the cross-sectional area of ​​the acupuncture points, and the depth of the limiting cavity is smaller than that of the acupuncture points, and the depth of the receiving groove is greater than that of the acupuncture points. The limiting cavity is small. When a plate is placed on the reverse side, the peripheral walls of the acupuncture points around the receiving groove form a restriction, so that objects can also be placed on the reverse side of the receiving groove. When several plates are stacked, two adjacent plates can be stacked up and down in opposite directions. The bottom of the limiting cavity of the upper plate is against the acupuncture points of the lower plate, so that the limiting cavity limits the stacking pressure depth. The peripheral walls of the acupuncture points are tilted outward at an angle of 5 to 14 degrees in the vertical direction, so that the acupuncture points of the upper plate can be stacked and penetrate into the acupuncture points of the lower plate. After adopting the above technical scheme, the beneficial effects of the present invention are as follows: the packaged items can be placed on both the front and the back, and the placement direction of the packaged items can be changed by turning the blister plate, thereby avoiding direct contact with the packaged items. The depths of the front and back sides of the receiving groove are different, which meets the different requirements of the packaged items for depth. In addition, the mold structure required is simple, the demoulding is fast, the finished product yield is high, and the production cycle is short, the material cost is low, the selection is wide, and the weight is light.

[0004] Although the above patent can realize that packaged items can be placed on both the front and back sides, since the receiving groove of the above blister tray is a square structure, it can only accommodate items with the same shape as the receiving groove, which limits the scope of application of the device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, the present invention provides a technical solution:

[0028] A blister tray for both front and back uses, comprising a blister tray body 1, the blister tray body 1 is made of polyethylene terephthalate, polyvinyl chloride, polystyrene, polypropylene, modified polyethylene terephthalate, acrylonitrile-butadiene-styrene copolymer, polylactic acid or high-impact polystyrene, a plurality of receiving grooves 2 are arranged side by side on the front of the blister tray body 1, the receiving grooves 2 are composed of a plurality of hexagonal grooves 3 arranged side by side, a receiving groove 2 4 is arranged on the back of the blister tray body 1 and located between the plurality of receiving grooves 2, the receiving groove 2 4 is composed of a plurality of hexagonal grooves 5 arranged side by side, and a plurality of receiving grooves 3 are arranged on the front of the blister tray body 1. A convex point 6 is arranged at each of the four corners of the face, a groove 7 is arranged at each of the four corners of the back side of the blister plate body 1, the groove 7 matches the convex point 6, a convex point 2 8 is arranged upwardly in the middle of the hexagonal groove 3, a groove 2 9 matching the convex point 2 8 is arranged downwardly in the middle of the hexagonal groove 2 5, the hexagonal groove 1 3 and the hexagonal groove 2 5 are both equilateral hexagons, and each internal angle is 120°, the depth of the accommodating groove 1 2 and the accommodating groove 2 4 is 0.50mm~5.00mm, the wall thickness of the blister plate body 1 is 0.5mm~1.5mm, the spacing between a plurality of accommodating grooves 2 is equal, and the spacing between a plurality of accommodating grooves 2 4 is equal.

[0029] like Figure 4 As shown, a receiving groove 2 is arranged on the front side of the blister tray body 1, which is composed of equilateral hexagonal grooves 3 arranged side by side. Strip objects can be stably placed in the hexagonal groove 3. Since the sides of the hexagons are equal, the strip objects can be evenly supported to prevent them from sliding or shifting. The receiving groove 2 4 arranged on the back side is also suitable for storing strip objects, realizing the double-sided use function.

[0030] like Figure 4 As shown, the shapes of hexagonal groove 1 3 and hexagonal groove 2 5 are perfectly matched with the hexagonal objects, and can accommodate a single hexagonal object separately. Each side of the hexagonal object is in close contact with the groove wall to ensure that it is firmly fixed to prevent shaking or falling off. The design of the front and back sides allows the blister tray to accommodate multiple hexagonal objects at the same time, thereby improving space utilization.

[0031] like Figure 4 As shown, due to the symmetry of the equilateral hexagon, the hexagonal groove 1 3 and the hexagonal groove 2 5 are compatible with rectangular objects. The four corners of the rectangular object are in contact with the groove wall of the hexagonal groove, providing a stable support effect to prevent the rectangular object from tilting or shifting during transportation or storage.

[0032] like Figure 5 As shown, the geometric structure of hexagonal groove 1 3 and hexagonal groove 2 5 can wrap the cylindrical objects to prevent them from rolling or shifting. The side of the cylindrical object contacts the groove wall of the hexagonal groove to ensure that it is firmly fixed in the groove. The design of the front and back sides allows the blister tray to store multiple cylindrical objects at the same time to meet batch storage needs.

[0033] like Figure 6 As shown, a convex point 2 8 is provided in the middle of the hexagonal groove 3, and the annular object can be put on the convex point 2 8 to achieve limited fixation; when storing objects with a circular structure, compared with the four-point support of the square groove in the prior art, the hexagonal structure of the device can achieve six-point support, so the stability is higher.

[0034] In this embodiment, the device solves the problem of limited application scope of existing blister trays, realizes multifunctional storage, double-sided use, stable stacking and efficient production, and has broad application prospects and market value.

[0035] Furthermore, the front and back sides of the blister tray can store items of different shapes at the same time. For example, the front receiving groove 2 can be used to place bar-shaped objects, and the back receiving groove 4 can be used to place ring-shaped objects, thereby realizing multifunctional mixed storage. Mixed storage improves the flexibility and application range of the blister tray and meets the needs of complex scenes.

[0036] Working principle: The front of the blister tray body 1 is provided with a receiving slot 2, which is composed of equilateral hexagonal slots 3 arranged side by side, and the back is provided with a receiving slot 4, which is composed of equilateral hexagonal slots 5 arranged side by side, and each inner angle is 120°, ensuring structural stability and symmetry. This design enables the receiving slot 2 and the receiving slot 4 to stably accommodate a single bar-shaped object, while the hexagonal slot 3 and the hexagonal slot 25 can separately accommodate hexagonal, rectangular, cylindrical and ring-shaped objects. The four corners of the front of the blister tray body 1 are provided with a convex point 6, and the four corners of the back are provided with a groove 7, and the groove 7 matches the convex point 6 to achieve stable stacking of multiple blister trays; the middle of the hexagonal slot 3 is provided with a convex point 8, and the middle of the hexagonal slot 25 is provided with a groove 29, and the groove 29 matches the convex point 28. When taking out an object, pushing from the direction of the groove 29 can drive the convex point 28 to push the object out of the slot. The depth of the receiving groove 1 2 and the receiving groove 2 4 is 0.50mm-5.00mm, and the wall thickness of the blister tray body 1 is 0.50mm-1.50mm, which can adapt to objects of different sizes and shapes while taking into account strength and lightness. In addition, the spacing between the receiving groove 1 2 and the receiving groove 2 4 is equal to ensure structural regularity and production efficiency.
