Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a fold-resistant blister packaging box. Background Technology

[0002] The main raw materials for blister packaging boxes include PVC, PS, PP, PET, PETG, as well as flocking, antistatic, and conductive materials. Blister packaging boxes are produced by the blister forming process. During the process, the plastic raw materials are heated at high temperatures and then vacuum-fled and cooled to form a plastic box shape. Due to their light weight, low cost, and flexibility that can reduce the impact of product collisions, blister packaging boxes have become the preferred packaging method for various products.

[0003] Referring to existing patent publication number CN222347742U, a fold-resistant blister packaging box includes a packaging box body, which includes a bottom box and a cover plate disposed on the top of the bottom box. The cover plate includes a top plate connected to the top of the bottom box, and a buckle plate is connected to one side of the top plate. This utility model, through the setting of reinforcing strips, helps to increase the stability of the connection between the bottom box and the cover plate, thereby improving the fold resistance of the cover plate and enhancing the product's usability.

[0004] Traditional blister packaging boxes are prone to damage after prolonged use, especially after repeated opening and closing or external impacts. This reduces the box's bending resistance and affects its reliability and lifespan. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fold-resistant blister packaging box. This invention utilizes a limiting component between the lid and the box body. During the folding process, when the lid opens and closes with the box body, both limiting parts connect to the first and second through holes. This cooperation between limiting parts strengthens the connection between the lid and the box body, preventing the lid from failing to close properly after prolonged bending and breakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fold-resistant blister packaging box, comprising:

[0008] The box body, as the main part of the packaging box, is used to hold and protect the items;

[0009] A box lid, integrally formed and connected to the upper part of the box body, wherein a limiting component is constructed between the surface of the box lid and the box body to cooperate with it;

[0010] The second limiting part is fixed to one side of the upper part of the box body. The inner side of the second limiting part is connected to the second elastic element. The surface of the box cover is provided with a second through hole corresponding to the second limiting part.

[0011] Both the box body and the lid are constructed with composite components inside, and the inner side of the box body is connected with a support component.

[0012] The present invention is further configured such that the limiting component includes: a connecting rod, a limiting part, an elastic element, and a through hole;

[0013] The connecting rod is installed at the lower part of the box cover, the limiting part is installed at the end of the connecting rod away from the box cover, the elastic element is connected to the inner side of the limiting part, and the through hole is opened through the upper side of the box body.

[0014] The present invention is further configured such that the through hole one corresponds to the limiting part one, and the maximum outer diameter of the limiting part one is greater than the diameter of the through hole one.

[0015] The present invention is further configured such that the limiting component is positioned away from the connection end between the box body and the box lid.

[0016] The present invention is further configured such that both the second limiting part and the first limiting part are constructed of an elastic material.

[0017] The present invention further provides that the composite component includes: a base layer, a connecting strip, a reinforcing layer, and an elastic layer;

[0018] The base layer is located inside the box body and the lid, and the surface of the base layer is provided with a connecting strip, a reinforcing layer and an elastic layer.

[0019] The present invention further provides that the support component includes: a support portion and a holding groove;

[0020] The support is located on the inner side of the box, and the holding slots are all formed on the surface of the support.

[0021] The beneficial effects of this utility model are as follows: By constructing a limiting component between the lid and the box body, when the lid is folded and connected to the box body, the limiting part one can be connected to the through hole one, and the limiting part two can also be connected to the through hole two. Thus, with the cooperation of the limiting part one and the limiting part two, the connection between the lid and the box body can be strengthened, and the lid can be prevented from being difficult to close to the box body after being bent and broken over a long period of time.

[0022] 1. This fold-resistant blister packaging box is equipped with composite components. Both the box body and the lid include an elastic layer, a reinforcing layer, and a connecting strip. The elastic layer, reinforcing layer, and connecting strip can be made of materials such as elastic PVC substrate, reinforcing mesh, and flexible connecting strip. The elastic PVC substrate provides good flexibility and load-bearing capacity, the reinforcing mesh enhances the structural strength of the packaging box, and the flexible connecting strip helps to form a fold-resistant connection between the box body and the lid.

[0023] 2. This foldable blister packaging box, by setting a limiting component, allows the lid to open and close with the box body during the folding process. Since both limiting part one and limiting part two have a certain degree of elasticity and are respectively connected to elastic element one and elastic element two inside, limiting part one can connect to through hole one, and limiting part two can also connect to through hole two. Thus, with the cooperation of limiting part one and limiting part two, the connection between the lid and the box body can be strengthened, preventing the lid from being difficult to close with the box body after being bent and broken for a long time.

[0030] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0031] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0032] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0033] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0034] Reference Figures 1 to 5 A fold-resistant blister packaging box includes: a box body 1, serving as the main body of the packaging box for holding and protecting items; a lid 2, integrally formed and connected to the upper part of the box body 1, for closing the box body 1 to prevent items from being exposed or contaminated by the outside environment; a limiting component is constructed between the surface of the lid 2 and the box body 1 to ensure that the lid 2 can tightly fit the box body 1 when closed, improving the sealing and protection of the packaging; and a limiting part 7, fixed to one side of the upper part of the box body 1, with an elastic element 15 connected to the inner side of the limiting part 7. A through hole 14 corresponding to the limiting part 7 is provided, so that when the lid 2 is closed with the box body 1, the locking mechanism can be released by pressing or pulling the limiting part 7 when it is necessary to open the lid 2; and when it is necessary to close the lid 2, the limiting part 7 and the elastic member 15 can automatically reset and lock into the through hole 14 to achieve locking; both the box body 1 and the lid 2 are internally constructed with composite components to enhance the strength and durability of the packaging, so as to improve the packaging's resistance to pressure and folding. The inner side of the box body 1 is connected with a support component for supporting and placing the packaged product.

[0035] Specifically, refer to Figure 2 , Figure 3 and Figure 5The limiting components include: a connecting rod 9, a limiting part 3, an elastic element 4, and a through hole 8. The connecting rod 9 is installed at the lower part of the lid 2, the limiting part 3 is installed at the end of the connecting rod 9 away from the lid 2, the elastic element 4 is connected to the inner side of the limiting part 3, and the through hole 8 is opened through the upper side of the box body 1. In this embodiment, when the lid 2 is closed, the connecting rod 9 pushes the limiting part 3 through the through hole 8 and engages with the through hole 8 on the box body 1. At this time, the elastic element 4 is in a compressed state, providing an outward pushing force to the limiting part 3, thereby ensuring that the lid 2 is firmly locked onto the box body 1.

[0036] Furthermore, the through hole 8 corresponds to the limiting part 3, and the maximum outer diameter of the limiting part 3 is greater than the diameter of the through hole 8. With this design, when the limiting part 3 passes through the through hole 8, they will form a tight fit. This tight fit helps to prevent the box lid 2 from opening accidentally, thereby ensuring the locking stability of the packaging.

[0037] Furthermore, the limiting component is configured to be located away from the connection end between the box body 1 and the box cover 2. This design allows the limiting component to move together with the box cover 2 and accurately match the limiting part 3 with the through hole 8, thereby improving the stability and accuracy of the connection.

[0038] Furthermore, both limiting part 2 7 and limiting part 1 3 are constructed of elastic material. This design allows limiting part 1 3 and limiting part 2 7 to be compressed to reduce their outer diameter when they move to through hole 1 8 and through hole 2 14 respectively. Then, when they pass through through hole 1 8 and through hole 2 14, they can return to their initial position and thus cannot easily detach from the through hole, thereby improving the connection strength.

[0039] Specifically, refer to Figure 4 The composite component includes: a base layer 13, a connecting strip 12, a reinforcing layer 11, and an elastic layer 10. The base layer 13 is constructed inside the box body 1 and the box lid 2. The surface of the base layer 13 is respectively provided with the connecting strip 12, the reinforcing layer 11, and the elastic layer 10. In this embodiment, the elastic layer 10, the reinforcing layer 11, and the connecting strip 12 can be made of materials such as elastic PVC substrate, reinforcing mesh, and flexible connecting strip. The elastic PVC substrate provides good flexibility and load-bearing capacity, the reinforcing mesh enhances the structural strength of the packaging box, and the flexible connecting strip helps to form a bending-resistant connection between the box body and the box lid to improve the bending resistance of the packaging box.

[0040] Specifically, refer to Figures 2 to 3 The support components include a support part 5 and a holding slot 6. The support part 5 is located inside the box body 1, and the holding slots 6 are all opened on the surface of the support part 5. In this embodiment, the support part 5 provides stable support for the items inside the box body 1, while the holding slots 6 provide space for the items to be stored in categories.

[0041] Working principle: When using this utility model, firstly, when opening and closing the packaging box, since both limiting part 3 and limiting part 7 have a certain elasticity and are respectively connected to elastic element 4 and elastic element 15, limiting part 3 can be connected to the through hole 8, and limiting part 7 can also be connected to the through hole 14. Thus, with the cooperation of limiting part 3 and limiting part 7, the connection between the lid 2 and the box body 1 can be strengthened, preventing the lid 2 from being difficult to close with the box body 1 after long-term bending and breakage. Both the box body 1 and the lid 2 include an elastic layer 10, a reinforcing layer 11, and a connecting strip 12. That is, the elastic layer 10, the reinforcing layer 11, and the connecting strip 12 can be made of materials such as elastic PVC substrate, reinforcing mesh, and flexible connecting strip. The elastic PVC substrate provides good flexibility and load-bearing capacity, the reinforcing mesh enhances the structural strength of the packaging box, and the flexible connecting strip helps to form a bending-resistant connection between the box body and the lid, thereby improving the bending resistance of the packaging box.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
