Description

Technical Field

[0001] This utility model belongs to the field of liquid fragrance technology, and in particular relates to a liquid fragrance sealing structure. Background Technology

[0002] Liquid fragrance products, such as aromatherapy diffusers and car air fresheners, are widely used in interior decoration, air purification, and personal care. Their quality and user experience largely depend on the performance of the sealing structure. Currently, common liquid fragrance sealing methods have several shortcomings. Some simple sealing structures simply use a plastic shell for direct encapsulation, resulting in poor sealing, easy evaporation of the fragrance liquid, a short lifespan, and frequent product replacements, increasing usage costs. While some products use sealing and breathable membranes, the edges of these membranes are in direct contact with outside air during storage, allowing the fragrance to easily evaporate from the edges. This results in the fragrance being almost completely evaporated before use, leading to waste and ultimately, an unsatisfactory sealing effect.

[0003] In today's pursuit of long-lasting and high-quality products, existing sealing structures are insufficient to meet the needs. Therefore, it is crucial to design a sealing structure that can effectively prevent the evaporation and deterioration of fragrance liquids during storage, while ensuring that the fragrance is properly released during use. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a liquid fragrance sealing structure that can provide multiple seals at the edges of the breathable membrane sealing layer, greatly enhancing the overall sealing effect. This effectively prevents the fragrance liquid from evaporating, deteriorating, and leaking during storage, while allowing for moderate diffusion during use. It is also simple and convenient to operate. This solves the problem that some existing products, although using structures such as sealed breathable membranes, still have edges that come into direct contact with outside air during storage, causing the fragrance to easily evaporate from the edges, resulting in waste of liquid fragrance and an unsatisfactory sealing effect.

[0005] This utility model is implemented as follows: a liquid fragrance sealing structure includes a storage box, the top outer wall of the storage box is integrally and fixedly connected with a sealing edge, a breathable membrane sealing layer is bonded and fixed between the inner side of the sealing edge and the top of the storage box, the interior of the storage box is used to place liquid fragrance, and an aluminum foil sealing layer is bonded and fixed between the sealing edge and the top of the breathable membrane sealing layer, the aluminum foil sealing layer covering the outer surface of the breathable membrane sealing layer.

[0006] As a preferred embodiment of this utility model, both the storage box and the sealing edge are made of transparent plastic. The storage box has a placement cavity inside, which is used to store liquid fragrance. The breathable membrane sealing layer is located on top of the placement cavity.

[0007] This design makes it easy to place liquid fragrances, and the transparent material allows for easy viewing of the liquid fragrance usage. It is convenient to use, and the breathable membrane sealing layer helps to seal the internal liquid fragrance to prevent leakage, while ensuring its breathability and the normal evaporation of the fragrance.

[0008] As a preferred embodiment of this utility model, a fixing groove is provided on the inner side of the sealing edge, and the breathable membrane sealing layer is bonded and fixed on the fixing groove.

[0009] This design facilitates the installation of the breathable membrane sealing layer, ensuring a tight connection to the top of the placement cavity. It also allows for the covering and sealing of the sidewall edges of the breathable membrane sealing layer, preventing aroma from evaporating from the edges during storage and improving the sealing effect.

[0010] In a preferred embodiment of this invention, the top of the sealing edge is provided as an adhesive portion, and the bottom of the aluminum foil sealing layer is fixed to the adhesive portion and the breathable membrane sealing layer by hot pressing.

[0011] This design facilitates a stable connection of the aluminum foil sealing layer. The aluminum foil sealing layer not only seals the surface of the breathable membrane sealing layer, but also facilitates the re-sealing of the joints between the edge of the breathable membrane sealing layer and the sealing edge. Thus, the sealing effect is greatly enhanced through the multiple sealing structures.

[0012] As a preferred embodiment of this invention, an aluminum foil handle is integrally and fixedly connected to the side wall of the aluminum foil sealing layer.

[0013] With this design, when the liquid fragrance needs to be opened for use, the aluminum foil handle makes it easy to peel off the aluminum foil seal, allowing the breathable membrane seal to come into contact with the air and achieve proper fragrance diffusion during use.

[0014] As a preferred embodiment of this invention, the breathable membrane sealing layer is made of polytetrafluoroethylene membrane material.

[0015] This design features excellent sealing and breathability, effectively preventing leakage of fragrance liquids and avoiding waste and pollution. At the same time, the good breathability ensures that fragrance molecules can pass through smoothly, allowing the fragrance to evaporate appropriately and continuously emit a pleasant aroma. It combines sealing and diffusion functions, providing a strong guarantee for the quality of liquid fragrances.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By cooperating with the sealing edge, fixing groove, breathable membrane sealing layer and aluminum foil sealing layer, the edge of the breathable membrane sealing layer can be covered and sealed, reducing the evaporation of fragrance from the edge and improving the sealing effect. In addition to sealing the surface of the breathable membrane sealing layer, it can also re-seal the joint between the edge of the breathable membrane sealing layer and the sealing edge. The multiple sealing structure greatly enhances the overall sealing effect and effectively prevents the fragrance liquid from evaporating, deteriorating and leaking during storage. When using the fragrance, it is convenient for users to peel off the aluminum foil sealing layer to allow the breathable membrane sealing layer to come into contact with the air, so as to achieve appropriate fragrance diffusion. The operation is simple and convenient. Attached Figure Description

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] refer to Figures 1 to 3 As shown in the figure, the liquid fragrance sealing structure provided by this utility model includes a storage box 1. A sealing edge 2 is integrally fixedly connected to the top outer wall of the storage box 1. A breathable membrane sealing layer 3 is bonded and fixed between the inner side of the sealing edge 2 and the top of the storage box 1. The interior of the storage box 1 is used to place liquid fragrance. An aluminum foil sealing layer 4 is bonded and fixed between the sealing edge 2 and the top of the breathable membrane sealing layer 3. The aluminum foil sealing layer 4 covers the outer surface of the breathable membrane sealing layer 3.

[0024] Specifically, the storage box 1 and the sealing edge 2 are both made of transparent plastic. The storage box 1 has a placement cavity 101 inside, which is used to store liquid fragrance. The breathable membrane sealing layer 3 is located on top of the placement cavity 101.

[0025] The above solution facilitates the placement of liquid fragrances, and the transparent material allows for easy viewing of the liquid fragrance usage. It is convenient to use, and the breathable membrane sealing layer 3 helps to seal the internal liquid fragrances to prevent leakage, while ensuring its breathability and the normal evaporation of the fragrance.

[0026] Specifically, a fixing groove 202 is provided on the inner side of the sealing edge 2, and the breathable membrane sealing layer 3 is bonded and fixed on the fixing groove 202.

[0027] The above solution facilitates the installation of the breathable membrane sealing layer 3, ensuring its tight connection to the top of the placement cavity 101. It also facilitates the covering and sealing of the side wall edges of the breathable membrane sealing layer 3, preventing the aroma from evaporating from the edges of the breathable membrane sealing layer 3 during storage and improving the sealing effect.

[0028] Specifically, the top of the sealing edge 2 is provided as an adhesive part 201, and the bottom of the aluminum foil sealing layer 4 is fixed to the adhesive part 201 and the breathable membrane sealing layer 3 by hot pressing.

[0029] The above scheme facilitates the stable connection of the aluminum foil sealing layer 4. The aluminum foil sealing layer 4 can not only seal the surface of the breathable membrane sealing layer 3, but also facilitate the re-sealing of the joint between the edge of the breathable membrane sealing layer 3 and the sealing edge 2. Thus, the sealing effect is greatly enhanced through the multiple sealing structure.

[0030] Specifically, an aluminum foil handle 401 is integrally fixedly connected to the side wall of the aluminum foil sealing layer 4.

[0031] Using the above solution, when the liquid fragrance needs to be opened for use, the aluminum foil handle 401 makes it easy to peel off the aluminum foil sealing layer 4, which in turn facilitates the breathable membrane sealing layer 3 to come into contact with the air, so as to achieve appropriate fragrance diffusion during use.

[0032] Specifically, the breathable membrane sealing layer 3 is made of polytetrafluoroethylene membrane material.

[0033] The above solution features excellent sealing and breathability, effectively preventing leakage of fragrance liquid and avoiding waste and pollution. At the same time, the good breathability ensures that fragrance molecules can pass through smoothly, allowing the fragrance to evaporate appropriately and continuously emit a pleasant aroma. It combines sealing and diffusion functions, providing a strong guarantee for the quality of liquid fragrance.

[0034] The working principle of this utility model:

[0035] When storing liquid fragrance, the breathable membrane sealing layer 3, combined with the sealing edge 2, the fixing groove 202, and the double seal after hot pressing of the aluminum foil sealing layer 4 and the adhesive part 201, effectively prevents the edge of the breathable membrane sealing layer 3 from contacting the outside air, enhances the sealing effect, and prevents fragrance leakage and excessive evaporation. The transparent storage box 1 makes it easy to observe the remaining amount. When using liquid fragrance, the aluminum foil sealing layer 4 is opened through the aluminum foil handle 401, exposing the breathable membrane sealing layer 3 to the air. Its good breathability allows fragrance molecules to pass through smoothly, achieving moderate evaporation and continuous fragrance emission, thus taking into account both sealed storage and effective emission functions.
