Description

Plastic tray

Technical Field

The invention relates to the technical field of plastic suction forming, in particular to a plastic suction tray.

Background

The plastic sucking process is mainly characterized by that after the flat plastic hard sheet material is heated and softened, it is adsorbed on the surface of mould by adopting vacuum adsorption, and after it is cooled, it is formed.

The plastic sucking tray is also called as plastic inner tray, which is made of plastic with a specific groove made of plastic hard sheets by plastic sucking process, and the product is placed in the groove to play the role of protecting and beautifying the product, and also has transportation type tray package.

A problem that present blister supporting plate exists is the blister shaping back, because it is mainly vertical to the recess to be limited to current technology recess, consequently when putting into the product recess back stack of the product that will pack, upper product can directly press and put on lower floor's product, in order to solve this problem, a method sets up asymmetric sunken in two relative borders of tray, as shown in figure 6, 7, behind the product packaging, need tray 180 degrees turning direction, make the border recess on upper strata and the border recess of lower floor stagger as shown in figure 8, can avoid upper product can directly press the problem of putting on lower floor's product like this. However, this method is labor intensive and inefficient.

Disclosure of Invention

The invention aims to solve the technical problems and provides a plastic uptake tray which is different from the conventional solution, the trays can be directly stacked without turning the direction by 180 degrees, and the problem that an upper product can be directly pressed on a lower product can be avoided.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a blister supporting plate, includes first recess and tray border, the opening direction of first recess is perpendicular with the up end of tray, be provided with a plurality of second recesses on the internal perisporium of first recess, the second recess is for first recess evagination, the up end of second recess with form first clearance between the up end of tray border or tray.

The utility model provides a blister supporting plate, includes first recess and tray border, the opening direction of first recess is perpendicular with the up end of tray, be provided with a plurality of third recesses on the internal perisporium of first recess, the third recess is for first recess indent, the lower terminal surface of third recess with form the second clearance between the lower terminal surface of tray.

The invention has the advantages that the side wall of the first groove is provided with the convex or concave structure, so that when the upper and lower plastic trays are stacked, a supporting stress point is generated in the vertical direction, products on the upper and lower trays can be effectively separated by a distance, and the extrusion of the upper product to the lower product is avoided.

Detailed Description

The invention is further described with reference to the following figures and examples.

In the first embodiment, as shown in fig. 1 and 2, a blister tray is composed of a plurality of first grooves 1 for accommodating products and a tray edge 3, and the upper end surface of the tray is arranged between adjacent grooves 1. The opening direction of the first groove 1 is vertical to the upper end face. The inner circumferential wall of the first groove 1 is provided with a second groove 2, and as shown in fig. 2, the second groove 2 is convex with respect to the first groove 1. In the present embodiment, a symmetrical arrangement on the opposite side walls of the first groove 1 is adopted. It is of course also possible to provide one or more second recesses on a single first recess 1. As shown in fig. 2, a first gap 4 is formed between the upper end surface of the second groove 2 and the edge of the tray or the upper end surface of the tray.

As shown in figure 4, during the use, put into first recess with product 5, two-layer plastic uptake tray stacks the back from top to bottom, and the lower terminal surface of the second recess 2 of upper layer plastic uptake tray just in time blocks on the tray border of lower floor's plastic uptake tray and the up end of tray, and the upper product can not directly be pressed on lower floor's product, the upper and lower direct extrusion problem of product of avoiding. It is noted that the thickness of the product should be less than the distance between the lower end surface of the tray and the upper end surface of the second recess 2.

Second embodiment, as shown in fig. 3, the present embodiment is different from the first embodiment in that the groove formed on the inner peripheral wall of the first groove 1 is such that the third groove 20 is recessed relative to the first groove 1, and a second gap 40 is formed between the lower end surface of the third groove 20 and the lower end surface of the tray.

As shown in figure 5, when the plastic tray is used, the product 5 is placed into the first groove, after the upper and lower plastic trays are stacked, the lower end face of the third groove 20 of the upper plastic tray is just clamped on the upper end face of the third groove 20 of the lower plastic tray, the upper product cannot be directly pressed on the lower product, and the problem of direct extrusion of the upper product and the lower product is solved. It is noted that the thickness of the product should be less than the distance between the lower end surface of the tray and the upper end surface of the third recess 20.

Although the technical scheme seems simple, the real difficulty is limited by the existing plastic uptake process. Particularly, when demoulding, demoulding is needed in the vertical direction, so that the second groove 2 or the third groove 20 arranged on the side wall of the first groove 1 can hinder demoulding, and the technical scheme can be smoothly realized only by designing a special mould device. The technical solution about the mold is described in another invention patent applied by the applicant on the same day.

As shown in fig. 6-8, the existing solution to solve the problem of squeezing the upper and lower trays is to use two opposite edges of the tray to set up asymmetric recesses 6, and after the product is packaged, the upper tray is turned 180 degrees when stacked. Thus, the lower end face of the groove 6 of the upper tray is pressed on the edge of the lower tray, and the thickness of the product is smaller than the depth of the groove 6.
