Description

Technical Field

[0001] This application relates to the field of packaging technology, specifically to the field of easy-to-remove vial sealing cap technology. Background Technology

[0002] Vials have long been widely used in the pharmaceutical field, especially for packaging injectables, vaccines, biological agents, and lyophilized medicines where high stability is required. Their standard structure typically includes a borosilicate glass vial, a flexible rubber stopper, and an external aluminum foil seal.

[0003] In pharmaceutical settings, the handling of vials is typically performed by healthcare professionals and is considered a specialized medical procedure. In this context, while traditional aluminum foil sealing requires significant peeling force and has sharp edges, its excellent tamper-proof properties and reliable sealing make it a widely accepted technical solution.

[0004] However, with the widespread use of highly active ingredients in the cosmetics industry, especially products containing easily deactivated ingredients such as peptides, growth factors, and antioxidant enzymes, more and more brands are beginning to draw on pharmaceutical packaging concepts and use vials as storage containers for high-end skincare products.

[0005] However, unlike the hospital environment, these products are ultimately aimed at ordinary consumers, whose age, gender, hand strength, and operating habits vary greatly, and who lack professional training and operating experience. In this context, the aluminum foil sealing design of traditional vials reveals its difficulty in opening. Furthermore, the edges of the aluminum foil, when partially curled up, can easily form sharp edges, causing skin scratches when opened by hand, posing a significant safety hazard.

[0006] Therefore, there is a market demand for sealing cap solutions that can eliminate the reliance on aluminum foil sealing and are suitable for non-professional users. Summary of the Invention

[0007] To address the aforementioned issues, this application proposes an easy-to-remove vial sealing cap, aiming to achieve a functional leap from "medical container" to "consumer-grade carrier" by designing a simple, safe, and reliable sealing cap solution that ensures a high degree of sealing and stability of the contents.

[0008] To achieve the above objectives, the present application adopts the following technical solution: An easy-to-remove vial sealing cap for use with a vial equipped with a rubber stopper, the vial including a body and a neck, the rubber stopper sealing the mouth and partially exposed at the top of the neck, the neck including a retaining ring and a concave neck; The sealing cap includes: A cap, covering the top of the rubber stopper; The skirt extends downward from the top edge of the cover and fits around the outer periphery of the bottleneck; A snap-fit ​​part is provided on the inner side of the lower end of the skirt, which is used to fit into the concave neck to fix the sealing cap on the vial and apply axial clamping force to the rubber stopper so that it maintains an interference seal with the bottle mouth; It also includes a release mechanism, which, when subjected to external force, drives the latch to undergo elastic deformation or displacement, disengaging from the concave neck, thereby releasing the pressure on the rubber stopper.

[0009] First, by setting a snap-fit ​​part at the lower end of the sealing cover skirt and embedding it into the concave neck of the bottleneck, the engagement between the snap-fit ​​part and the concave neck can achieve a "self-locking" effect during assembly, forming a stable axial mechanical locking structure, which replaces the traditional aluminum foil seal. While ensuring that the sealing cover is firmly fixed, it avoids the problem of opening difficulties caused by the excessive adhesive strength of aluminum foil.

[0010] Furthermore, the release mechanism allows users to apply only slight external force (such as pushing or lifting with their fingers) to drive the buckle to elastically deform or displace, quickly disengaging it from the concave neck and completing the overall disassembly of the sealing cover.

[0011] In some possible implementations, the sealing cap is detachably assembled from two symmetrical semi-cylindrical cap bodies to form an annular structure surrounding the bottleneck; The two covers are hinged at their respective fitting parts by a pivot structure at one end, and the other end is provided with a fastening part that can be fastened and unfastened. The fastening part constitutes a release mechanism for opening the sealing cover.

[0012] In some possible implementations, the fastening part is a plug-in snap-fit.

[0013] In some possible implementations, the cap has a sealing portion extending to the other cap side at the rubber stopper corresponding to the vial, and the other cap side has a corresponding clearance groove.

[0014] In some possible implementations, a first pressing block is also provided on the outer periphery of the skirt corresponding to the fastening portion.

[0015] In some possible real-time configurations, a localized area of ​​the skirt of the sealing cap is hollowed out to form a weak groove, which constitutes a release mechanism for opening the sealing cap. When subjected to external force, the weak groove undergoes localized deformation, causing the latch to disengage from the concave neck.

[0016] In some possible implementations, the number of weak grooves is two, symmetrically arranged on both radial sides of the sealing cover.

[0017] In some possible implementations, the weak groove extends to the top of the cover and covers part of the top of the cover.

[0018] In some possible implementations, a second push block is also included, which is disposed on the skirt edge.

[0019] In some possible implementations, the second push block is located at the lower end of the skirt. Attached Figure Description

Detailed Implementation

[0021] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art: It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0023] First, let me describe the vials 100 that will be sealed and stored in this application. Please refer to [link / reference needed]. Figure 9The vial includes a body 110 and a neck 120. The neck 120 includes a retaining ring 121 and a concave neck 122. A rubber stopper 130 is sealed at the bottle opening and partially exposed at the top of the neck 120. In conventional vial packaging, after the rubber stopper 130 is inserted into the bottle opening, it is sealed with aluminum foil up to the retaining ring 121 to further seal the rubber stopper 130. However, this requires removing the aluminum foil seal during use, which is somewhat difficult and inconvenient for users.

[0024] The main impacts are as follows: the high seal between the aluminum foil and the bottle opening requires considerable force to pry open, making it extremely difficult, especially for users with short nails, insufficient hand strength, or joint flexibility issues. Secondly, the edges of the aluminum foil, once partially lifted, can easily form sharp flanges, potentially causing skin scratches when opened by hand, posing a significant safety hazard. For example, to open the bottle smoothly, consumers are often forced to use auxiliary tools such as keys, scissors, or nail clippers, which not only undermines the clean user experience the product should provide but also greatly increases the risk of secondary contamination.

[0025] To address this, this application presents a novel, easily removable sealing cap to replace the traditional aluminum foil structure. The specific implementation is as follows (see Example 1). Figures 1 to 4 The sealing cap includes a top 1, a skirt 2, and a snap-fit ​​portion 3, wherein the top 1 covers the top of the rubber stopper 130. The skirt 2 extends downward from the edge of the top 1 and fits around the outer periphery of the bottleneck, primarily covering at least the retaining ring portion 121.

[0026] The snap-fit ​​part 3 is located on the inner side of the lower end of the skirt 2 and is used to fit into the concave neck 122 to fix the sealing cap on the vial 100 and apply axial pressure to the rubber stopper 130 so that it maintains an interference seal with the bottle mouth.

[0027] Thus, by setting a snap-fit ​​part 3 at the lower end of the skirt 2 of the sealing cover and embedding it into the concave neck 122 of the bottleneck, the engagement of the snap-fit ​​part 3 and the concave neck 122 can achieve a "self-locking" effect during the assembly process, forming a stable axial mechanical locking structure, which replaces the traditional aluminum foil sealing. While ensuring that the sealing cover is firmly fixed, it avoids the problem of opening difficulties caused by the excessive adhesive strength of the aluminum foil.

[0028] Furthermore, the sealing cap of this application is provided with a release mechanism, which is a measure to facilitate the release of the sealing structure as described above. When subjected to external force, the snap-fit ​​part 3 is driven to undergo elastic deformation or displacement, disengaging from the concave neck 122, thereby releasing the pressure on the rubber stopper 130.

[0029] Thus, through the release mechanism, the user only needs to apply a slight external force (such as pushing or lifting with a finger) to drive the buckle part 3 to produce elastic deformation or displacement, quickly disengaging from the concave neck 122 and completing the overall disassembly of the sealing cover.

[0030] In this embodiment, the sealing cap is detachably assembled from two symmetrical semi-cylindrical cap bodies 11 to form an annular structure surrounding the bottleneck. The two cap bodies 11 are hinged at their respective fitting portions via a pivot structure 12 at one end, and the other end is provided with a fastening portion 13 that can be fastened and unfastened, which constitutes a release mechanism for opening the sealing cap.

[0031] Specifically, the fastening part 13 is a plug-in buckle, that is, one end of the fastening part 13 will separate. At this time, one end will have a fastening protrusion 131, which will be locked when inserted into the other end of the cover 11, thereby achieving fastening and sealing.

[0032] Furthermore, the cap 11 has a sealing portion 111 extending to the other cap 11 side at the rubber stopper 140 corresponding to the vial 100, and the other cap 11 side has a corresponding clearance groove 112.

[0033] For ease of release, as part of the release mechanism, a first pushing block 14 is provided on the outer periphery of the skirt 2 corresponding to the fastening part 13. Preferably, the first pushing block 14 is located at the upper end of the skirt 2. In use, the release method is horizontal pushing, and its location at the upper end makes operation easier.

[0034] In terms of materials, transparent materials such as AS (acrylonitrile styrene copolymer) and PC (polycarbonate) can be used, as well as materials such as PET (polyethylene terephthalate).

[0035] When using materials such as AS and PC, the connection method for the hinge structure 12 can be a metal hinge. Common applications include cosmetic foundation cases and high-end makeup mirrors, which will not be elaborated upon further. Alternatively, for materials with good mechanical properties such as PET, the hinge structure 12 can be made of rigid plastic in a single molded piece. Utilizing the inherent flexibility of the plastic material, a thin and flexible section can be created through injection molding, allowing the lid to open and close repeatedly without the need for additional metal shafts or other components. This is used in fields such as pharmaceutical bottles and packaging.

[0036] Example 2, please refer to Figures 5 to 8 Example 2 is another implementation of the release mechanism based on Example 1. The sealing method is not described again in this example.

[0037] A partial area of ​​the skirt 2 of the sealing cap is hollowed out to form a weak groove 21. The weak groove 21 constitutes a release mechanism for opening the sealing cap. When subjected to external force, it undergoes local deformation, causing the latching part 3 to disengage from the concave neck 122. In other words, by hollowing out the partial skirt 2 and the corresponding latching part 3, the overall sealing cap has a gap, which will also create a stress point when subjected to external force, causing local deformation, thereby allowing the latching part 3 to disengage smoothly.

[0038] Preferably, there are two weak grooves 21, symmetrically arranged on both radial sides of the sealing cover. Furthermore, the weak grooves 21 extend to the top of the cover 1 and cover a portion of it; that is, the weak grooves 21 extend and hollow out a portion of the top of the cover 1, reducing the force required to open the cover.

[0039] To facilitate finding the stress point, a second pushing block 22 is provided in the hollowed-out remaining skirt edge 2. The second pushing block 22 is located at the lower end of the skirt edge 2. In this embodiment, the disassembly of the sealing cover will be performed by lifting it upwards. Therefore, it is located at the lower end to facilitate the force and release the buckle part 3.

[0040] As stated above, this case protects an easily detachable vial seal, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
