Description

Technical Field

[0001] This utility model belongs to the field of beverage preservation technology, and more specifically, it relates to a preservation container. Background Technology

[0002] In daily life, specific containers such as breast milk bottles, baby bottles, and wine bottles often require external preservation containers for cooling or chilling after containing corresponding liquids (such as breast milk, formula, and alcohol) to effectively delay spoilage and maintain their quality or taste. Existing preservation containers developed for this purpose typically have built-in insulation structures (such as a preservation cylinder or heat insulation layer). Utilizing heat insulation materials or phase change materials, they prevent external heat transfer or internal cold loss for a limited time, thus achieving the core function of maintaining a low-temperature internal environment.

[0003] Existing food storage containers typically employ a one-piece, non-removable design for their core insulation structure. This design presents challenges in cleaning, particularly in the event of accidental leakage, spills, or long-term residue buildup. Users cannot easily disassemble the container or directly access the hard-to-reach interior areas for effective cleaning, which not only easily leads to bacterial growth and odors but also compromises the container's hygiene and safety. Therefore, this study aims to research and improve upon existing structures and address their shortcomings, providing a food storage container with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a food preservation container, which is achieved by the following specific technical means:

[0005] A food preservation container includes an outer cylinder and a food preservation cylinder, the food preservation cylinder being placed inside the outer cylinder. A sealing cap is connected to the top of the outer cylinder. The food preservation cylinder is composed of at least two sets of arc-shaped shells of the same shape spliced ​​together, and the arc-shaped shells are connected by a fastening ring. The arc-shaped shell is a hollow structure, and a liquid inlet is provided at the top, and a sealing plug is inserted into the inlet.

[0006] Furthermore, at least two sets of fixing grooves are provided on the outer side of the arc-shaped shell for installing fastening rings; the width of the fixing grooves is adapted to the width of the fastening rings.

[0007] Furthermore, the fastening ring is made of elastic material.

[0008] Furthermore, the two sets of splicing sides of the arc-shaped shell are respectively provided with positioning protrusions and positioning grooves at equal intervals. The positioning grooves are provided in correspondence with the positioning protrusions and can be adapted to each other.

[0009] Furthermore, each of the inner bottom ends of the arc-shaped shell is provided with a base plate, which is a hollow structure and integrally formed with the arc-shaped shell; multiple sets of protruding strips are provided at equal intervals on the inner side of the arc-shaped shell.

[0010] Furthermore, both the outer cylinder and the sealing cap are composed of an insulation layer and a protective sleeve, with the insulation layer located inside the protective sleeve; the insulation layer is made of EPP material, and the protective sleeve is made of silicone material.

[0011] Furthermore, two sets of connecting ears are symmetrically arranged on the outer side of the protective sleeve of the outer cylinder for installing hanging ropes or carrying straps.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By designing the food storage container as a split structure composed of at least two sets of arc-shaped shells connected and secured with fastening rings, the pain point of cleaning the inside of traditional one-piece insulated containers is solved. Users can easily disassemble each arc-shaped shell to directly contact and thoroughly clean its inner and outer surfaces and splicing corners, effectively preventing stains and bacterial growth, and significantly improving the hygiene, safety, and lifespan of the container. At the same time, when the diameter of the bottle or cup is slightly larger than the internal diameter of the food storage container, the elastic fastening rings, together with the split arc-shaped shell structure, can be appropriately expanded to adapt to containers of different sizes, thereby increasing the product's applicability.

[0014] 2. The positioning protrusions and grooves on the side of the arc-shaped shell ensure splicing accuracy and reliability. The bottom support plate enhances the overall structural stability, preventing cups or bottles from slipping off the bottom of the refrigerator. The bottom support plate and the arc-shaped shell are an integral hollow structure, further increasing the filling capacity of the cold storage liquid and extending the preservation time. Multiple sets of equidistant protrusions on the inner side of the arc-shaped shell allow users to quickly remove or insert cups or bottles, providing high ease of use. Furthermore, the multiple sets of protrusions effectively improve the structural strength of the arc-shaped shell, providing good impact resistance.

[0015] 3. The outer cylinder and sealing cap of this utility model are both composed of an insulation layer and a protective sleeve. The insulation layer is made of EPP material, which has excellent heat insulation and low thermal conductivity, effectively reducing heat transfer, maintaining stable internal temperature, and reducing energy loss. The protective sleeve is made of silicone material, which has high elasticity, high and low temperature resistance, and anti-aging properties, can adapt to complex environments, and can effectively protect the insulation layer. It also has waterproof and easy-to-clean properties. Compared with the shell structure made of existing metal materials, it is lightweight and easy for users to carry and use.

[0028] Example:

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides a food preservation container, including an outer cylinder 1 and a food preservation cylinder 3. The food preservation cylinder 3 is placed inside the outer cylinder 1. A sealing cap 2 is connected to the top of the outer cylinder 1. The food preservation cylinder 3 is composed of three sets of arc-shaped shells 301 of the same shape, and the arc-shaped shells 301 are connected by fastening rings 302. The arc-shaped shells 301 are hollow structures, and a liquid inlet is provided at the top. A sealing plug 303 is inserted into the inlet. This solves the problem of traditional one-piece insulated containers being difficult to clean thoroughly. The food preservation cylinder 3 is constructed by splicing detachable arc-shaped shells 301, allowing users to easily disassemble each shell and directly contact all internal surfaces for thorough cleaning. This effectively removes residual stains, prevents bacterial growth and odor generation, and greatly improves the hygiene and safety of the container. At the same time, the hollow structure allows for the filling of phase change materials or heat insulation materials through the inlet, ensuring excellent heat preservation / cold preservation performance. The sealing plug 303 ensures the sealing of the filling.

[0031] The outer side of the arc-shaped shell 301 is provided with at least two sets of fixing grooves 304 for installing fastening rings 302. The width of the fixing grooves 304 is adapted to the width of the fastening rings 302. The fixing grooves 304 provide a precise installation position and a reliable constraint track for the fastening rings 302, ensuring that the fastening rings 302 can be stably fitted on the outer side of all arc-shaped shells 301, achieving effective clamping and fixing of each shell, preventing them from accidentally coming apart during use, and ensuring the structural integrity and stability of the assembled preservation cylinder 3.

[0032] Among them, the fastening ring 302 is made of elastic material (such as silicone or rubber), which gives it good deformation ability and recovery force. This allows the fastening ring 302 to be easily stretched and fitted into the fixing groove 304 or removed, greatly simplifying the disassembly and assembly operation. At the same time, its elasticity can continuously provide appropriate radial pressure when tightened, ensuring that each arc-shaped shell 301 fits tightly and is not easy to loosen, maintaining the stability of the splicing structure. In addition, when the diameter of the bottle or cup is slightly larger than the internal diameter of the food preservation tube 3, the elastic fastening ring 302, together with the split arc-shaped shell 301 structure, can be appropriately expanded to adapt to containers of different sizes and improve the applicability of the product.

[0033] The two sets of splicing sides of the arc-shaped shell 301 are respectively provided with positioning protrusions 305 and positioning grooves 306 at equal intervals. The positioning grooves 306 are correspondingly provided with the positioning protrusions 305 and can be adapted to each other. The mechanical interlocking structure formed by the positioning protrusions 305 and the positioning grooves 306 can automatically guide each shell to be accurately aligned when splicing the arc-shaped shell 301, which greatly improves the splicing efficiency and accuracy and effectively prevents misalignment or sliding between shells. This cooperation relationship enhances the structural strength and stability of the splicing point and ensures the overall rigidity and shape retention of the preservation cylinder 3.

[0034] The inner bottom of the arc-shaped shell 301 is provided with a bottom plate 307. After the arc-shaped shell 301 is assembled, the bottom plates 307 can be spliced ​​together to form a limiting structure to ensure that the inserted bottle will not slip off the bottom of the preservation cylinder 3. The bottom plate is a hollow structure and is integrally formed with the arc-shaped shell. When in use, the bottom plate can hold cold storage liquid to further increase the filling capacity of the cold storage liquid and extend the preservation time. The inner side of the arc-shaped shell 301 is provided with multiple sets of equidistant convex strips to facilitate users to quickly pull out or quickly put in the cup or bottle from the preservation cylinder 3, which has high ease of use. At the same time, the setting of multiple sets of convex strips can also effectively improve the structural strength of the arc-shaped shell 301 and has good impact resistance.

[0035] The outer cylinder 1 and the sealing cap 2 are both composed of an insulation layer and a protective sleeve. The insulation layer is located inside the protective sleeve. The insulation layer is made of EPP material, which has excellent heat insulation and low thermal conductivity, effectively reducing heat transfer, maintaining stable internal temperature, and reducing energy loss. The protective sleeve is made of silicone material, which has high elasticity, resistance to high and low temperatures (-50℃~200℃), and anti-aging properties. It can adapt to complex environments and effectively protect the insulation layer. It is also waterproof and easy to clean, which is beneficial for daily use. Compared with the shell structure made of existing metal materials, it is lightweight and easy for users to carry and use.

[0036] The outer sleeve of the outer cylinder 1 has two sets of connecting ears 101 symmetrically arranged on the outside for installing hanging ropes or carrying straps.

[0037] The working principle of this embodiment is as follows: First, multiple arc-shaped shells 301 filled with insulating material (such as phase change material) and fitted with sealing plugs 303 are precisely aligned and spliced ​​into a complete preservation cylinder 3 by using the positioning protrusions 305 and positioning grooves 306 on the splicing side. Then, elastic fastening rings 302 are inserted into the fixing grooves 304 on the outside of each arc-shaped shell 301 and tightened to form a stable insulating core structure. Next, the assembled preservation cylinder 3 is placed inside the outer cylinder 1 to ensure its stable placement. Then, the sealing cap 2 is screwed onto the top of the outer cylinder 1 to seal the container. In use, a bottle or cup containing liquid to be preserved (such as breast milk, milk, or wine) is placed inside the preservation cylinder 3. The preservation cylinder 3 uses the insulating material in its hollow layer to block the transmission of external heat or the loss of internal cold, maintaining the low-temperature environment of the inner bottle. During cleaning, loosening the fastening ring 302 allows the food preservation cylinder 3 to be completely disassembled into a single arc-shaped shell 301, facilitating thorough cleaning of all internal and external surfaces of the components.
