DETAILED DESCRIPTION
[0024] In order to make the technical problem, technical scheme and beneficial effect of the utility model to be solved clearer and more apparent, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.
[0025] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0026] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the utility model and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0027] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.
[0028] The blister tray is widely used, and can be used for electronic product packaging, medical packaging, food packaging, etc. The conventional blister tray is designed as a flat product pit position, and a right-angle groove is used at the outer periphery to identify the direction and limit the horizontal and stacking. The empty tray can be tightly stacked, and only the edge groove is used for limiting. When the product is higher than the groove limit, the product will be squeezed, which cannot guarantee the quality of the product. Please refer to Figure 1 , Figure 1 The conventional two blister trays 20 are cross-sectional views. When there is no product placed in the blister tray 20, the blister trays 20 can be tightly stacked together. After the product is placed, only the edge groove limits the stacking, and the product is easily squeezed by the blister tray 20, which causes the product to deform, break, etc. For example, the placed product is a transformer, and the outer tape winding height has differences in the production process, which causes the large stacking layer to produce tape deformation and damage under pressure, which easily causes serious quality risk of power adapter safety certification.
[0029] In order to alleviate and solve the above technical problems, the present application provides a new blister tray 10. The blister tray 10 comprises a bottom wall 11 and a peripheral side wall 12. The bottom wall 11 is provided with a partition structure 13.
