Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet food packaging technology, and in particular to metal cans for pet food. Background Technology
[0002] With the rapid development of the pet industry and the continuous improvement of people's living standards, more and more people are choosing to keep pets. As people pay more attention to pet food safety, various kinds of canned pet food have appeared on the market to ensure pet food safety. Currently, counterfeit pet food is rampant in the market, and people cannot directly determine whether the pet food they buy is a counterfeit product, leading to problems of being unable to trace the source of food safety incidents.
[0003] In existing technologies, to achieve traceability of pet food cans, an NFC (Near Field Communication) chip is placed on the can. People can quickly identify the product information of the pet food can by identifying the information on the NFC chip. However, to ensure the safe storage and transportation of pet food cans, they need to be made of metal. Metal materials can interfere with the signal of the NFC chip, leading to unstable communication or failure to function properly, which in turn affects the success rate of identifying the NFC chip on the pet food can.
[0004] Therefore, there is an urgent need to invent metal cans for pet food to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide metal cans for pet food that can be quickly identified using an NFC chip, while ensuring a high success rate for NFC chip identification.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] Metal cans for pet food include:
[0008] The container has a cavity for holding pet food, and the upper end of the cavity has an opening;
[0009] A cover plate is used to seal the opening; both the cover plate and the accommodating box are made of metal.
[0010] An insulating boss, fixed to the outer surface of the accommodating housing and extending outward, the insulating boss having an insulating function; and
[0011] An NFC chip is fixed to the end of the isolation protrusion away from the housing, and the NFC chip stores information about the pet food.
[0012] As an optional feature, the accommodating box is provided with a flange, which is provided on the box wall at the opening and extends outward.
[0013] As an optional solution, the accommodating box is a triangular prism extending in the vertical direction, and the horizontal cross-sectional area of the accommodating box gradually increases as it extends from bottom to top.
[0014] As an optional solution, the side edges of the accommodating box are all rounded.
[0015] As an optional embodiment, the outer peripheral wall of the accommodating box includes a curved portion and a flat portion, and the isolation boss is disposed on the flat portion.
[0016] As an optional solution, the projections of the NFC chip and the isolation protrusion along the vertical direction are located within the projection of the upper end of the accommodating box along the vertical direction.
[0017] Alternatively, the isolation protrusion can be bonded and fixed to the housing body, and the isolation protrusion can be bonded and fixed to the NFC chip.
[0018] As an optional solution, the NFC chip includes:
[0019] The chip body stores information about the pet food; and
[0020] A protective film is wrapped around the surface of the chip body and is fixedly connected to the isolation protrusion. The protective film is made of a microwave absorbing material.
[0021] As an optional solution, the cover plate is fastened and fixed to the accommodating box, and a pull ring is provided on the cover plate.
[0022] As an optional solution, the cover plate is provided with a tearing structure, the structural strength of which is lower than the structural strength of the rest of the cover plate.
[0023] The beneficial effects of this utility model are:
[0024] The metal can of pet food provided by this utility model has a cavity inside the container to hold the pet food. An opening at the top of the cavity, sealed with a lid, ensures airtight storage of the pet food and facilitates easy removal of the food from the container. The metal construction of both the container and lid enhances the structural strength of the can, improving protection during transportation and storage. An outward-extending isolation protrusion on the outer surface of the container holds an NFC chip containing pet food information at the end furthest from the container. This allows the identification device to quickly obtain the pet food information after scanning the NFC chip. The insulating nature of the isolation protrusion separates the NFC chip from the metal container and lid, reducing interference from the metal and improving the success rate of NFC chip recognition.

[0032] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] In related technologies, to ensure pet food safety and achieve traceability of pet food cans, NFC (Near Field Communication) chips can be embedded in the cans. People can quickly identify product information by scanning the NFC chip. However, to ensure the safe storage and transportation of pet food, the cans need to be made of metal. Metal materials can interfere with the NFC chip's signal, leading to unstable communication or malfunction, which in turn affects the success rate of identifying the NFC chip on the pet food can.
[0037] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment provides a container 100, a cover 200, an isolation boss 300, and an NFC chip 400. The container 100 has a cavity 110 for holding pet food, and the upper end of the cavity 110 has an opening 111. The cover 200 is used to seal the opening 111. Both the cover 200 and the container 100 are made of metal. The isolation boss 300 is fixed to the outer surface of the container 100 and extends outward. The isolation boss 300 has an insulating function. The NFC chip 400 is fixed to the end of the isolation boss 300 away from the container 100. The NFC chip 400 stores information about the pet food.
[0038] The metal can of pet food, with a receiving cavity 110 within the housing 100, can accommodate pet food. An opening 111 is created at the top of the receiving cavity 110, and a cover 200 seals the opening, achieving airtight storage of the pet food within the receiving cavity 110. This also facilitates subsequent removal of the pet food from the housing 100 through the opening 111. By ensuring that both the housing 100 and the cover 200 are made of metal, the structural strength of the metal can of pet food is guaranteed, improving the protection of the pet food during transportation and storage. An outwardly extending isolation protrusion 300 is provided on the outer surface of the housing 100. The NFC chip 400 storing pet food information is fixed at the end of the isolation protrusion 300 away from the housing 100. This enables the identification device to quickly obtain pet food information after scanning the NFC chip 400. By ensuring that the isolation protrusion 300 has an insulating function, the NFC chip 400 can be separated from the housing 100 and the cover plate 200 made of metal material, reducing the signal interference of metal to the NFC chip 400, thereby ensuring the success rate of the identification device in recognizing the NFC chip 400.
[0039] It should be noted that in this embodiment, both the housing 100 and the cover 200 are made of aluminum, and the isolation boss 300 is made of foam. Aluminum has good corrosion resistance and can protect food from contamination and spoilage. The foam not only insulates the NFC chip 400 from the housing 100 and the cover 200, but also provides cushioning against collisions between the NFC chip 400 and the outside world, improving the protection of the NFC chip 400. In other embodiments, the housing 100 and the cover 200 may also be made of tinplate or other metals, and the isolation boss 300 may also be made of rubber or other insulating materials; this embodiment does not impose specific limitations.
[0040] As an optional solution, the cover 200 is fastened and fixed to the container body 100, and a pull ring is provided on the cover 200. By fastening and fixing the cover 200 to the container body 100, the pet food contained in the receiving cavity 110 is sealed and stored. By providing a pull ring on the cover 200, when the sealed pet food is taken out, the pull ring can be grasped to open the cover 200, improving the efficiency of opening the metal can of the pet food.
[0041] To further facilitate the disassembly of the latched cover 200 and the receiving box 100, a tear structure is provided on the cover 200. The structural strength of the tear structure is lower than that of the rest of the cover 200. When the latched cover 200 and the receiving box 100 are disassembled, the cover 200 is pulled by hand using the pull ring. The tear structure at the upper end of the cover 200 will break first, thus achieving the effect of the cover 200 breaking along the tear structure and being disassembled from the receiving box 100. It should be noted that, in this embodiment, the tear structure is an annular groove formed along the contour shape of the opening 111. The thickness of the cover 200 at the annular groove is less than the thickness at other locations of the cover 200, so that the annular groove can break first when the cover 200 is subjected to tensile force.
[0042] As an optional solution, the NFC chip 400 includes a chip body and a protective film. The chip body stores information about pet food, and the protective film is wrapped around the surface of the chip body and fixedly connected to the isolation protrusion 300. The protective film is made of a microwave-absorbing material. By wrapping the surface of the chip body with a protective film made of microwave-absorbing material and fixing it to the isolation protrusion 300, signal interference from the housing 100 and the cover 200 to the chip body can be further reduced. It should be noted that the specific structure and information storage principle of the chip body are existing technologies and will not be described in detail here.
[0043] In this embodiment, the isolation protrusion 300 is bonded and fixed to the housing 100, and the isolation protrusion 300 is bonded and fixed to the protective film. By using adhesive bonding to fix the isolation protrusion 300 to the housing 100 and to the protective film, the stable assembly of the chip body inside the NFC chip 400 and the housing 100 can be ensured, solving the problem that the NFC chip 400 is prone to falling off the housing 100 during transportation.
[0044] In one alternative embodiment, the container 100 is provided with a flange 120, which is located on the container wall at the opening 111 and extends outward. By providing an outwardly extending flange 120 on the container wall at the opening 111, the structural strength of the container 100 can be improved, and the sharp edges on the container wall at the opening 111 can be replaced with rounded corners, making it easier to pick up the metal can of pet food.
[0045] Combination Figure 1 and Figure 2 The specific structure of the accommodating box 100 is described below. The accommodating box 100 is a triangular prism extending in the vertical direction. The horizontal cross-sectional area of the accommodating box 100 gradually increases from bottom to top to improve the aesthetics of the accommodating box 100.
[0046] In addition, the side edges of the container 100 are rounded to ensure that the metal can of the pet food has no sharp edges, thus improving safety.
[0047] To facilitate the fabrication of the isolation boss 300, the outer peripheral wall of the housing 100 includes a curved portion and a flat portion, with the isolation boss 300 disposed on the flat portion. Since the chip body is plate-shaped, bending of the chip body should be avoided as much as possible when fixing the chip body. By placing the isolation boss 300 on the flat portion, it is only necessary to ensure that the isolation boss 300 is also plate-shaped. When the isolation boss 300 is bonded and fixed to the flat portion, and the NFC chip 400 is bonded and fixed to the isolation boss 300, the chip body and housing 100 can be assembled and fixed without bending the chip body, reducing the assembly difficulty of the NFC chip 400, the isolation boss 300, and the housing 100.
[0048] As an optional solution, the isolation protrusion 300 extends outward from the end near the receiving box 100 by a distance of 5mm to 10mm. By extending the isolation protrusion 300 outward by 5mm to 10mm from the end near the receiving box 100, and fixing the NFC chip 400 to the end of the isolation protrusion 300 away from the receiving box 100, the NFC chip 400 can be isolated from the receiving box 100 by 5mm to 10mm, effectively avoiding signal interference from the receiving box 100 and the cover plate 200 to the chip body inside the NFC chip 400. It should be noted that in this embodiment, the isolation protrusion 300 extends outward by 8mm from the end near the receiving box 100. In other embodiments, the extension distance of the isolation protrusion 300 can be arbitrarily adjusted within the range of 5mm to 10mm according to actual needs; this embodiment does not impose a specific limitation.
[0049] As an alternative, in other embodiments, the vertical projections of the NFC chip 400 and the isolation protrusion 300 are located within the vertical projection of the upper end of the housing 100. By ensuring that the vertical projections of the NFC chip 400 and the isolation protrusion 300 are located within the vertical projection of the upper end of the housing 100, the maximum horizontal dimension of the metal can of pet food can be ensured to be located at the upper end of the housing 100. When packaging the metal can of pet food, only the packaging box size needs to be designed based on the upper dimension of the housing 100, which facilitates packaging. Furthermore, since the horizontal dimension of the NFC chip 400 is smaller than the horizontal dimension of the upper end of the housing 100, the upper end of the housing 100 can also serve as a shielding structure above the NFC chip 400, improving the protection of the NFC chip 400.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
