Description

A transparent tin can for health supplements Technical Field

[0001] This utility model relates to the field of storage jars, and in particular to a transparent iron jar for health supplements. Background Technology

[0002] Tonics are supplements that replenish nutrients lacking in the human body, enhance the body's disease resistance, and eliminate weakness. A deficiency in certain essential substances can easily lead to illness or physical weakness; consuming tonics replenishes these deficiencies, promoting recovery. Currently, tonics on the market are often packaged, transported, and sold in fully enclosed tin cans. While these cans offer some protection, consumers must open them to observe the color, shape, and quantity of the tonics. This not only increases the risk of product spoilage but also exposes the tonics to air, making them prone to absorbing dust and moisture, accelerating deterioration and affecting their medicinal properties and nutritional value. Furthermore, some tonics are susceptible to mold and insect infestation during storage, which consumers cannot detect in time, leading to the purchase of substandard products. This harms consumer rights and damages the reputation of businesses. Therefore, we are introducing a transparent tonic tin can. Summary of the Invention

[0003] The main purpose of this utility model is to provide a transparent metal can for health supplements, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A transparent tonic can includes a can body with a groove at the upper edge of the can body. A bottom insertion ring is fixedly connected to the lower part of the inner wall of the can body, and an inner ring is fixedly connected to the upper part of the inner wall of the can body. A bottom plate is inserted into the bottom insertion ring, and the outer surface of the bottom plate is fixedly connected to the inner wall of the can body. A sleeve assembly is movably sleeved in the groove, and a transparent component is movably engaged in the sleeve assembly.

[0006] Preferably, the transparent component includes a connecting frame, a transparent cover is fixedly connected to the upper part of the inner wall of the connecting frame, and a slot is formed on the outer surface of the connecting frame.

[0007] By adopting the above technical solution: the visible transparent cover is made of food-grade polyethylene terephthalate (PET). Food-grade PET material meets national food safety standards, is non-toxic and odorless, has stable chemical properties, will not react chemically with tonics, and will not release harmful substances, thus ensuring that the safety and quality of tonics are not affected, and consumers can use it with confidence.

[0008] Preferably, the sleeve assembly includes a can lid, with an elastic protruding ring fixedly connected to the lower part of the inner wall surface of the can lid, and an elastic locking protrusion fixedly connected to the upper part of the inner wall surface of the can lid.

[0009] By adopting the above technical solution, the elastic convex ring makes the installation and disassembly of the socket assembly very simple. During installation, simply align the can lid with the can body and press down gently. The elastic convex ring can adaptively adjust its position and embed into the socket groove. During disassembly, simply pull the can lid upward. The deformation capability of the elastic structure allows the socket assembly to be easily separated without the need for additional tools, greatly improving the convenience of use for users. Whether it is for merchants to replenish stock or consumers to take out health supplements, the operation can be completed quickly.

[0010] Preferably, the can lid is movably fitted into the groove of the can body via an elastic convex ring.

[0011] By adopting the above technical solution: the elastic convex ring of the can lid is movably connected to the groove of the can body. When the can lid is pressed down, the elastic convex ring, with its own good elastic deformation ability, tightly fits the inner wall of the groove, forming a tight sealing barrier.

[0012] Preferably, the size of the elastic locking protrusion is adapted to the size of the locking groove and the position is corresponding, and the elastic locking protrusion is movably locked in the locking groove.

[0013] By adopting the above technical solution: the elastic locking protrusion is adapted to the size and position of the locking groove. When the transparent component is installed on the can lid, the elastic locking protrusion is squeezed and undergoes elastic deformation, thus embedding into the locking groove. After installation, the elastic locking protrusion returns to its original shape, tightly filling the space of the locking groove, generating greater friction and locking force, and firmly fixing the transparent component on the can lid.

[0014] Preferably, the lower part of the outer surface of the connecting frame is provided with a beveled edge that is wider at the top and narrower at the bottom, and the lower end of the connecting frame is provided with a rounded edge.

[0015] By adopting the above technical solutions: the upper wide and lower narrow beveled edge design on the lower part of the outer surface of the connecting frame and the rounded corner edge design at the lower end of the connecting frame, a guiding role can be played when installing the transparent component to the can lid. When the connecting frame approaches the elastic locking protrusion on the inner wall of the can lid, the beveled edge and the rounded corner edge will guide the elastic locking protrusion to automatically align with the locking groove, reducing the time for manual adjustment and making the installation process smoother.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, through the set transparent component, the user can directly see the state of the tonic inside the can without opening the can lid. The locking groove on the outer surface of the connecting frame is adapted to the elastic locking protrusion on the upper part of the inner wall of the can lid. By utilizing the elastic deformation of the elastic locking protrusion, when the transparent component is pressed, it is embedded into the locking groove to form a stable connection and build a stable viewing window. This avoids the pollution and loss of the tonic caused by repeatedly opening the lid to check, and effectively ensures the purity and medicinal properties of the tonic.

[0018] 2. In this utility model, the elastic protruding ring at the lower part of the inner wall of the can lid is movably connected to the groove at the upper end of the can body. Due to the elastic properties of the elastic protruding ring, it can fit tightly against the inner wall of the groove when the can lid is pressed, forming a sealing structure. At the same time, the snap-fit ​​between the visible component and the can lid further enhances the overall sealing performance. The double sealing mechanism effectively isolates external dust and moisture pollutants, reduces the contact between the tonic and the air, inhibits oxidation and moisture absorption, thereby extending the shelf life of the tonic and ensuring its nutritional value and efficacy.

[0019] 3. In this utility model, the lower part of the outer surface of the connecting frame is designed with a beveled edge that is wider at the top and narrower at the bottom, and the lower end is set as a rounded edge, which reduces the installation resistance between the visible component and the can lid. During installation, the beveled edge and the rounded edge can guide the elastic locking protrusion to quickly align with the locking groove. During disassembly, the user only needs to lift it simply, and the elasticity of the elastic locking protrusion can easily separate the component. The whole operation process is simple and efficient, which improves the convenience of the user in using the tonic can. Attached Figure Description
