Abstract
Description
Technical Field
[0001] This utility model relates to the field of food storage products technology, and in particular to a food can. Background Technology
[0002] Currently, most food glass jars on the market (such as sauce bottles, storage jars, and beverage cups) are made of ordinary soda-lime glass or tempered glass. Although they have advantages such as high transparency and good chemical stability, they have the following technical defects in actual use:
[0003] Poor temperature adaptability and unpleasant feel: Ordinary glass has a limited temperature resistance range. When containing excessively hot (such as freshly boiled liquids) or excessively cold (such as frozen drinks) contents, the surface temperature of the can changes drastically, causing users to experience a noticeable "scalding" or "freezing" discomfort when holding it. Although some products use a double-layered glass structure for insulation, this increases weight and cost, and still cannot solve the problem of a slippery surface caused by low-temperature condensation.
[0004] Poor impact resistance and high risk of breakage: Glass is brittle, especially when dropped vertically. A direct impact of the bottle bottom or body onto a hard surface (such as tile or cement) can easily cause it to crack, resulting in leakage of contents and potentially creating glass shards, posing a safety hazard. Existing solutions often involve simply wrapping the bottle with a rubber ring or attaching a shock-absorbing sticker, offering limited protection and affecting aesthetics and cleanliness. Utility Model Content
[0005] The purpose of this invention is to provide a food can that solves the problems existing in the prior art and improves the temperature adaptability and impact resistance of the food can.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] A food container includes a borosilicate glass bottle body and a PP bottle cap, wherein the borosilicate glass bottle body and the PP bottle cap are detachably and sealed together; the outer periphery of the borosilicate glass bottle body is covered with a silicone sleeve for heat insulation and drop protection.
[0008] In an exemplary embodiment, the high borosilicate glass bottle body includes a bottle mouth, an upper part of the bottle body, a lower part of the bottle body, and a bottle bottom arranged sequentially from top to bottom, and the silicone sleeve is fitted around the lower part of the bottle body and the outer periphery of the bottle bottom.
[0009] In one exemplary embodiment, a sealing elastic gasket is provided in the area where the inner circumference of the PP bottle cap contacts the bottle opening.
[0010] In an exemplary embodiment, the outer diameter of the bottle opening is smaller than the outer diameter of the upper part of the bottle body, and there is a smooth transition between the upper part of the bottle body and the bottle opening.
[0011] In one exemplary embodiment, the outer diameter of the lower part of the bottle body is smaller than the outer diameter of the upper part of the bottle body, and there is a smooth transition between the upper part of the bottle body and the lower part of the bottle body. The outer diameter of the silicone sleeve fitted around the lower part of the bottle body is the same as the outer diameter of the upper part of the bottle body.
[0012] In one exemplary embodiment, the lower part of the bottle body is divided into an upper half and a lower half from top to bottom, and the outer diameter of the lower half gradually decreases from top to bottom.
[0013] In one exemplary embodiment, the lower half of the bottle body and the bottom of the bottle form a smooth transition.
[0014] In one exemplary embodiment, the silicone sleeve fitted onto the lower outer periphery of the bottle body has a viewing hole.
[0015] In one exemplary embodiment, the top of the PP bottle cap is provided with a recess.
[0016] In one exemplary embodiment, the recess is provided with a thin-walled region for indicating a vacuum-sealed state, the thickness of which is less than the thickness of other regions of the recess.
[0017] The present invention achieves the following technical advantages over the prior art:
[0018] By incorporating a high borosilicate glass bottle body, a PP cap, and a silicone sleeve, the high borosilicate glass bottle body is heat-resistant, capable of withstanding rapid temperature changes from -20℃ to 180℃, and is impact-resistant, transparent, and safe. The PP cap is lightweight and non-toxic, and the PP material has excellent food-grade safety, while its good processing performance ensures a reliable sealing effect. The silicone sleeve provides heat insulation and drop protection, comprehensively improving the temperature adaptability and impact resistance of the food can.
[0019] Other technical solutions disclosed in this utility model also have the following technical advantages:
[0020] By setting a sealing elastic gasket in the area where the inner circumference of the PP bottle cap contacts the bottle mouth, the defect of insufficient deformation capacity of PP material is compensated. The thermal expansion coefficients of high borosilicate glass and PP are quite different. Through the elastic deformation compensation mechanism of the sealing elastic gasket, the risk of seal failure caused by thermal expansion and contraction can be buffered. It can adapt to a wider range of temperature changes, improve the reliability of the seal, and prevent liquid leakage. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0034] The purpose of this invention is to provide a food can that solves the problems existing in the prior art and improves the temperature adaptability and impact resistance of the food can.
[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] Please refer to Figures 1 to 6 This embodiment provides a food can, including a borosilicate glass bottle body 1 and a PP bottle cap 2. The borosilicate glass bottle body 1 and the PP bottle cap 2 are detachably and sealed together, specifically by means of threaded connection, snap-fit, etc. A silicone sleeve 3 for heat insulation and shock protection is fitted around the outer periphery of the borosilicate glass bottle body 1. The borosilicate glass bottle body 1 is heat-resistant, able to withstand rapid temperature changes from -20℃ to 180℃, impact-resistant, and transparent and safe. The PP bottle cap 2 is made of food-grade PP (polypropylene) material, which is lightweight, non-toxic, and has excellent food-grade safety. Its good processing performance ensures a reliable sealing effect. The silicone sleeve 3 provides heat insulation and shock protection, thus improving the overall temperature adaptability and impact resistance of the food can.
[0037] Specifically, the high borosilicate glass bottle body 1 includes, from top to bottom, a bottle mouth 101, an upper part of the bottle body 102, a lower part of the bottle body 103, and a bottom 104. A silicone sleeve 3 is fitted around the lower part of the bottle body 103 and the bottom 104. The segmented design of the high borosilicate glass bottle body 1 optimizes structural strength and stress distribution (separating the upper pressure-bearing area from the lower support area), improving overall compressive strength. The silicone sleeve 3 only covers vulnerable areas, namely the lower part of the bottle body 103 and the bottom 104, reducing the amount of silicone material used while ensuring protection, thus lowering costs and balancing economy and practicality. The upper part of the bottle body 102 is exposed, preserving the transparency of the glass for easy observation of the contents, thus balancing aesthetics and functionality.
[0038] In this embodiment, a sealing elastic gasket is provided in the area where the inner circumference of the PP bottle cap 2 contacts the bottle opening 101. The sealing elastic gasket compensates for the insufficient deformation capacity of PP material. Since the coefficients of thermal expansion of high borosilicate glass and PP differ significantly, the elastic deformation compensation mechanism of the sealing elastic gasket can buffer the risk of seal failure caused by thermal expansion and contraction, adapt to a wider range of temperature changes, improve seal reliability, and prevent liquid leakage. The sealing elastic gasket can be made of food-grade safe materials such as silicone rubber, ethylene propylene diene monomer (EPDM), or thermoplastic elastomers (TPE / TPES).
[0039] The outer diameter of the bottle mouth 101 is smaller than the outer diameter of the upper part of the bottle body 102, which reduces the contact area between the bottle mouth 101 and the PP bottle cap 2, lowers the processing precision requirements, and at the same time, the larger diameter of the upper part of the bottle body 102 provides users with a more comfortable point of force to open the cap; the upper part of the bottle body 102 and the bottle mouth 101 are smoothly transitioned, ensuring the feel when holding the bottle, eliminating stress concentration points, avoiding the risk of micro-cracks caused by right-angle connections, and extending the life of the glass bottle body.
[0040] The outer diameter of the lower part 103 of the bottle is smaller than the outer diameter of the upper part 102 of the bottle, and there is a smooth transition between the upper part 102 and the lower part 103. The outer diameter of the silicone sleeve 3, which is fitted around the lower part 103, is the same as the outer diameter of the upper part 102. The reduced outer diameter of the lower part 103 and the matching outer diameter of the silicone sleeve 3 with the upper part 102 create a non-slip stepped structure. This achieves a non-slip texture design, optimizes the grip, and reduces the amount of glass material used through structural optimization, thus optimizing manufacturing costs while ensuring product functionality.
[0041] In this embodiment, the lower part 103 of the bottle is divided into an upper part 1031 and a lower part 1032 from top to bottom. The outer diameter of the lower part 1032 gradually decreases from top to bottom, and the tapering method can be a streamlined shape as shown in the figure. Dividing the lower part 103 of the bottle into upper and lower functional areas, the upper part 1031 maintains a columnar structure to ensure strength, while the lower part 1032 adopts a tapering design to disperse the bottom stress, reduce the local impact when falling vertically, and at the same time avoid the rigidity of a straight cylindrical structure and enhance the streamlined appearance.
[0042] The lower half 1032 and the bottom of the bottle 104 have a smooth transition, which is the same as the smooth transition between the upper part of the bottle body 102 and the bottle mouth 101. This ensures a good tactile feel when holding the bottle, eliminates stress concentration points at the bottom, avoids the risk of micro-cracks caused by right-angle connections, and extends the life of the glass bottle. At the same time, the bottom of the inner part of the high borosilicate glass bottle body 1 can also adopt a rounded corner smooth transition, which makes it easy to thoroughly clean residual liquid.
[0043] The silicone sleeve 3, which is fitted around the lower part 103 of the bottle, has a viewing hole 301. While maintaining the protective function of the silicone sleeve 3, the contents can be directly observed through the partial opening, such as the remaining amount of contents and the state of the liquid. At the same time, the amount of silicone used can be reduced, the cost can be optimized, and the opening can also serve as an anti-slip texture to aid gripping.
[0044] The PP bottle cap 2 has a recessed portion 201 at its top, with a thin-walled region 202 for indicating the vacuum seal status. The thickness of the thin-walled region 202 is less than the thickness of other areas of the recessed portion 201. The stepped structure formed by the recessed portion 201 acts as a structural reinforcement, improving the cap's pressure resistance. The thin-walled region 202 serves as a sensitive indicator of vacuum seal, reflecting the internal pressure status of the container in real time. When a vacuum forms inside the food can, the thin-walled region 202 is pressed in by atmospheric pressure, creating a noticeable depression. If the pressure inside the can increases due to spoilage and gas production, the vacuum level decreases, and the depression bulges out, commonly known as "can bulging," indicating to consumers that the product may have spoiled. Furthermore, the thinness of the thin-walled region 202 results in a low deformation threshold, allowing for earlier response to minute pressure changes and enhancing the reliability of food safety monitoring.
[0045] This embodiment achieves a triple improvement in safety (drop resistance, temperature resistance), functionality (sealing, vacuum indication), and user experience (grip and easy cleaning) through a combination of high borosilicate glass, PP, and silicone materials, along with a segmented bottle body, a tapered lower part of the bottle body, and a recessed cap. It is suitable for high-frequency, multi-scenario food container needs.
