Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a lightweight lifting ring structure for oyster sauce cans. Background Technology

[0002] Oyster sauce cans are special containers for holding oyster sauce. The mouth of the can has threads and a positioning ring from top to bottom. The lid is screwed onto the mouth of the can by threads. There is usually a lifting ring installed below the positioning ring of the oyster sauce can, so customers can lift the oyster sauce can to carry it.

[0003] However, the handles of existing lifting rings are often angular plastic handles that are easy to hurt your hands and lack comfort. In addition, existing lifting rings are usually solid parts that are injection molded in one piece, and there is still room for improvement in terms of weight reduction. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a lightweight lifting ring structure for oyster sauce cans, which solves the problem that the handle of the existing lifting ring is not comfortable, and that the existing lifting ring is usually a solid part that is injection molded in one piece, and there is still room for improvement in terms of lightweighting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A lightweight lifting ring structure for oyster sauce cans includes a collar, a left lifting strap and a right lifting strap connected to the collar, and a hollow gripping component. The two ends of the gripping component are fixedly connected to the ends of the left and right lifting straps, respectively. The side of the gripping component facing the collar is an arc surface. The gripping component has a lightweight reinforcing structure inside, which is used to reduce the weight of the gripping component while improving its axial and radial load-bearing strength.

[0006] Compared with the prior art, the beneficial effects of this utility model are: The grip component of this application features a curved surface design on the side facing the collar, which naturally conforms to the palm and provides a smooth and comfortable grip during lifting operations. This effectively avoids the hand-gripping problem caused by traditional angular structures. At the same time, the grip component uses a hollow structure combined with an internal lightweight reinforcing structure design to reduce weight while improving axial load-bearing strength and radial bending strength. This ensures structural integrity while minimizing material usage, solving the technical contradiction of traditional lifting rings where lightweighting results in insufficient strength and reinforcing results in increased weight. This achieves the best balance between weight and strength. Attached Figure Description

Detailed Implementation

[0008] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0009] Example 1 like Figure 1 , Figure 3 As shown, a lightweight lifting ring structure for an oyster sauce can includes a collar 2, a left lifting strap 6 and a right lifting strap 4 connected to the collar 2, and a hollow gripping component 5. The top surface of the collar 2 is provided with multiple locking teeth 1 that are inclined toward the center of the collar 2 and arranged in a ring around the center of the collar 2. When the bottom surface of the collar 2 is pressed down on the mouth of the oyster sauce can, the locking teeth 1 are squeezed and elastically deformed by the mouth of the can. When the locking teeth 1 pass through the positioning ring of the oyster sauce can, the locking teeth 1 rebound. At this time, the collar 2 is lifted and the top surface of the locking teeth 1 is squeezed and contacted with the bottom surface of the positioning ring. The two ends of the gripping component 5 are fixedly connected to the ends of the left lifting strap 6 and the right lifting strap 4, respectively. The side of the gripping component 5 facing the collar 2 is an arc surface. The gripping component 5 is provided with a lightweight reinforcing structure 7 inside. The lightweight reinforcing structure 7 is used to reduce the weight of the gripping component 5 while improving the axial and radial load-bearing strength of the gripping component 5. The lightweight reinforcing structure 7 is a periodically arranged honeycomb unit that can cope with lateral pressure and longitudinal pressure. The top and bottom surfaces of the left lifting strap 6 and the right lifting strap 4 are provided with diamond-shaped weight-reducing grooves 3. The weight-reducing grooves 3 on the top and bottom surfaces of the left lifting strap 6 are arranged correspondingly to each other, and the depth of each weight-reducing groove 3 on the left lifting strap 6 is less than half the height of the left lifting strap 6. The weight-reducing grooves 3 on the top and bottom surfaces of the right lifting strap 4 are arranged correspondingly to each other, and the depth of each weight-reducing groove 3 on the right lifting strap 4 is less than half the height of the right lifting strap 4. The distance between the bottom of two corresponding weight-reducing grooves 3 is 1mm. The collar 2, the locking teeth 1, the left lifting strap 6, and the right lifting strap 4 are integrally injection molded from plastic material.

[0010] In this embodiment, the gripping component 5 of this application adopts an arc-shaped design on the side facing the collar 2, which can naturally conform to the palm and provide a smooth and comfortable gripping experience during lifting operations. This effectively avoids the problem of hand discomfort caused by traditional angular structures. At the same time, the gripping component 5, through the design of a hollow structure combined with an internal lightweight reinforcing structure 7, achieves weight reduction while improving axial load-bearing strength and radial bending strength. This ensures structural integrity while minimizing material usage, thus solving the technical contradiction of traditional lifting rings where lightweighting results in insufficient strength and reinforcing results in increased weight. To achieve the optimal balance between weight and strength, this application also provides diamond-shaped weight-reducing grooves 3 on the left lifting strap 6 and the right lifting strap 4, which can further reduce the weight of the lifting ring. At the same time, the two corresponding weight-reducing grooves 3 are not interconnected, and a plastic film layer with a thickness of 1mm is left between them. When the lifting ring is lifted, although the lateral load capacity of the plastic film layer is weak, it can still withstand the longitudinal load. At this time, the solid plastic material part between the weight-reducing grooves 3 can be used as a reinforcing rib. Through the combination of the reinforcing rib and the plastic film layer, sufficient strength can be provided while reducing weight.

[0011] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 2 and Figure 4 As shown, the lightweight reinforcing structure 7 consists of periodically arranged corrugated units, and the top and bottom surfaces of the left lifting strap 6 and the right lifting strap 4 are provided with rectangular weight-reducing grooves 3.

[0012] In this embodiment, the corrugated unit can better cope with longitudinal pressure, and the rectangular weight-reducing groove 3 has strong resistance to deformation. The combination of the two can cope with heavy oyster sauce cans.

Various modifications and variations can be made to this application by those skilled in the art.
