Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more particularly to a detachable desiccant assembly and packaging cap. Background Technology

[0002] In the packaging of humidity-sensitive products such as electronic products, food, pharmaceuticals, medical devices, precision instruments, and chemical materials, it is usually necessary to place desiccants in sealed containers to absorb internal moisture, control environmental humidity, and thus prevent the products from becoming damp, moldy, oxidized, or deteriorating in performance.

[0003] Currently, common desiccant assembly methods mainly include:

[0004] Bagged desiccants: Granular desiccants are sealed in breathable paper or non-woven bags and directly placed into the packaging container. In this method, the desiccant bags are prone to shifting, piling up, or even breaking during transportation or handling, leading to uneven moisture absorption or product contamination. In addition, on automated packaging lines, it is more difficult to grasp, position, and place loosely bagged desiccants, affecting production efficiency.

[0005] One-piece molded desiccant: Desiccant granules are bonded to a part of the packaging container (such as the bottom cover or inner liner) through injection molding, die casting, or other methods. While this method can secure the desiccant, it cannot be replaced, making the entire packaging component a disposable item, which is detrimental to environmental protection and cost control. Once the desiccant is saturated with moisture, the entire component must be discarded, resulting in material waste. In addition, the one-piece molding process is complex, and material bonding issues may affect the desiccant's air permeability and moisture absorption efficiency.

[0006] In summary, the existing desiccant assembly methods suffer from a combination of drawbacks, including difficulty in achieving stable reliability, assembly compatibility, replaceability, and environmental friendliness. Summary of the Invention

[0007] The purpose of this invention is to provide a detachable desiccant assembly and packaging cap, which solves the problem that existing desiccant assembly methods have comprehensive defects in terms of fixation reliability, assembly compatibility, replaceability and environmental protection.

[0008] To achieve the above objectives, the present invention provides a detachable desiccant assembly, the detachable desiccant assembly comprising a shell and a desiccant body, the shell having a receiving cavity, the inner bottom of the receiving cavity being provided with at least one snap-fit ​​portion, the desiccant body being an injection-molded integral structure, the shape of the desiccant body being adapted to the inner bottom of the receiving cavity, and the outer side wall of the desiccant body being provided with a mating portion that cooperates with the snap-fit ​​portion;

[0009] The desiccant body is detachably snapped into the bottom of the receiving cavity by the snap-fit ​​part and the mating part.

[0010] The snap-fit ​​part is a snap-fit ​​structure extending from the bottom of the receiving cavity, and the mating part is a snap-fit ​​protrusion provided on the outer wall of the desiccant body, wherein the snap-fit ​​structure snaps into the snap-fit ​​protrusion.

[0011] The claw structure is interference-fitted with the cam.

[0012] The claw structure has elastic deformation capability.

[0013] The outer wall of the shell is provided with a breathable structure.

[0014] The ventilated structure is a ventilated opening formed on the side wall of the housing.

[0015] The present invention also provides a packaging cap for use in a detachable desiccant assembly as described above. The packaging cap is detachably mounted on the housing. A positioning protrusion is provided on the inner sidewall of the housing. A spiral sliding groove is provided on the outer sidewall of the packaging cap near the end of the housing. A guide opening and an elastic locking protrusion are respectively provided at both ends of the spiral sliding groove.

[0016] This invention discloses a detachable desiccant assembly and packaging cap, comprising a shell and a desiccant body. By setting the desiccant body as an injection-molded integral structure, it becomes a solid component with a regular shape and certain structural strength, eliminating the hidden dangers of bagged desiccant being easily damaged or displaced, and facilitating automated production line handling and assembly, thus solving the problems of fixation reliability and assembly compatibility. Secondly, by setting the snap-fit ​​part at the bottom of the receiving cavity of the shell and setting the mating part on the outer side wall of the desiccant body to cooperate with it, the two are detachably snapped together. When the desiccant is saturated with moisture, the desiccant body can be replaced separately while the shell can be retained for reuse, solving the replaceability problem and avoiding the material waste caused by discarding the entire assembly, thus meeting environmental protection requirements.

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Please see Figure 1 and Figure 2 The present invention provides a detachable desiccant assembly, the detachable desiccant assembly including a housing 101 and a desiccant body 102, the housing 101 having a receiving cavity 103, the inner bottom of the receiving cavity 103 being provided with at least one snap-fit ​​part 104, the desiccant body 102 being an injection-molded integral structure, the shape of the desiccant body 102 being adapted to the inner bottom of the receiving cavity 103, and the outer side wall of the desiccant body 102 being provided with a mating part 105 that cooperates with the snap-fit ​​part 104;

[0024] The desiccant body 102 is fixed to the inner bottom of the receiving cavity 103 by the detachable snap-fit ​​of the snap-fit ​​part 104 and the mating part 105.

[0025] In this embodiment, by setting the desiccant body 102 as an injection-molded integral structure, it becomes a solid component with a regular shape and certain structural strength. This eliminates the hidden dangers of bagged desiccant being easily damaged or displaced, and facilitates automated production line handling and assembly, solving the problems of fixation reliability and assembly compatibility. Secondly, by setting the snap-fit ​​part 104 at the bottom of the receiving cavity 103 of the housing 101, and setting the mating part 105 on the outer side wall of the desiccant body 102 to cooperate with it, the two are detachably snapped together. When the desiccant is saturated with moisture, the desiccant body 102 can be replaced separately while the housing 101 can be retained for reuse. This solves the replaceability problem and avoids material waste caused by discarding the entire component, thus meeting environmental protection requirements.

[0026] Furthermore, the snap-fit ​​portion 104 is a snap-fit ​​structure extending from the inner bottom of the receiving cavity 103, and the mating portion 105 is a snap-fit ​​protrusion disposed on the outer wall of the desiccant body 102, wherein the snap-fit ​​structure snaps into the snap-fit ​​protrusion.

[0027] In this embodiment, the claw structure is preferably a protruding component extending vertically from the inner bottom of the receiving cavity 103, and the corresponding locking protrusion is recessed into the lower part of the outer side wall of the desiccant body 102. During assembly, the desiccant body 102 is pressed into the receiving cavity 103 axially. When the claw structure contacts the desiccant body 102, it makes a slight clearance. After the desiccant body 102 is in place, the claw structure springs back and embeds into the locking protrusion, thereby achieving dual axial and circumferential limiting.

[0028] Furthermore, the claw structure is interference-fitted with the cam.

[0029] In this embodiment, when the claw structure engages with the protrusion, a pre-tightening force is generated between them, eliminating the assembly gap and effectively preventing the desiccant body 102 from relative shaking or abnormal noise during transportation due to vibration or bumps.

[0030] Furthermore, the claw structure has elastic deformation capability.

[0031] In this embodiment, when the desiccant body 102 is assembled, the desiccant body 102 squeezes the claw structure to make it elastically open; when the desiccant body 102 is installed in place, the claw structure automatically resets and engages with the protrusion by relying on elastic restoring force.

[0032] Furthermore, a ventilated structure 106 is provided on the outer side wall of the housing 101, and the ventilated structure 106 is a ventilated opening formed on the side wall of the housing 101.

[0033] In this embodiment, humid air inside the container equipped with the removable desiccant assembly can freely enter and exit the receiving cavity 103 through the vent opening, fully contacting and being absorbed by the desiccant body 102. This ensures that the moisture absorption function of the desiccant body 102 is effectively utilized.

[0034] Please see Figure 3 The present invention also provides a packaging cover 201, which is applied to the detachable desiccant assembly as described above. The packaging cover 201 is detachably installed on the housing 101. A positioning protrusion 202 is provided on the inner side wall of the housing 101. A spiral sliding groove 203 is provided on the outer side wall of the packaging cover 201 near the end of the housing 101. A guide opening 204 and an elastic locking protrusion 205 are respectively provided at both ends of the spiral sliding groove 203.

[0035] In this embodiment, the positioning protrusion on the housing 101 slides into the guide opening 204 on the packaging cover 201, and then rotates to the elastic locking protrusion 205 via the spiral sliding groove 203 to lock, thereby completing the installation of the packaging cover 201. The packaging cover 201 and the housing 101 adopt a separate independent design, and the two are quickly assembled and separated through a detachable connection structure. When the desiccant 102 is saturated with moisture and needs to be replaced, the user only needs to remove the packaging cover 201 from the housing 101 to expose the desiccant 102 in the receiving cavity 103 for replacement, avoiding interference of the packaging cover 201 with the disassembly and assembly process of the desiccant 102. After replacement, the packaging cover 201 can be reinstalled on the housing 101 for reuse.

[0036] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
