Description

Technical Field

[0001] This utility model relates to the field of canning technology, and in particular to a fish can that is easy to open. Background Technology

[0002] Canned fish, as a common ready-to-eat canned product, occupies an important position in the food market. It is usually made from fresh or frozen fish as the base material and undergoes a series of rigorous processing procedures, including pre-treatment such as scaling, gutting, and cleaning. Then it is canned, with carefully formulated seasonings added precisely, followed by sealing, and finally undergoes a strict sterilization process to ensure the safety and shelf life of the product.

[0003] Currently, there are two main sealing methods for fish cans: pull-tab and screw-top. Pull-tab cans offer the advantage of being extremely easy to open; consumers can simply pull the tab to quickly open the can and access the contents. However, screw-top cans present a different challenge. Due to friction between the threads, depending on the can's seal and the can's design, operators often need to apply considerable force to overcome this friction and successfully rotate and open the can. This can be particularly inconvenient for those with less strength, such as the elderly, children, or those with limited hand strength or dexterity. It may even prevent them from fully consuming the fish. While some screw-top cans can be opened relatively easily by hand in certain situations, the overall user experience still falls short of the convenience of pull-tab sealing. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a fish can that is easy to open, with the feature of being able to unscrew the lid with little effort, which is simple and convenient.

[0005] The technical solution adopted by this utility model is as follows: a can body with an upward opening and an internal receiving cavity is provided. A sealing film for sealing is sealed at the opening of the can body. A can lid with a downward opening is threaded to the top of the can body in the vertical direction. The can lid extends outward in the vertical direction to form a thickened area. An operating slot is provided on the thickened area. A film-cutting component for cutting open the sealing film is provided in the operating slot. A first anti-slip texture is arranged in a circumferential array on the outer wall of the can lid.

[0006] Preferably, in order to enable the operating slot to be used in conjunction with the film-cutting assembly, one end of the operating slot is provided with an internal thread.

[0007] Preferably, in order to enable the threaded connection end to engage with the internal thread, the slicing assembly includes a threaded connection end, which is threadedly connected to the internal thread on one end of the operating slot, and one end of the threaded connection end is provided with a spike.

[0008] Preferably, in order to drive the threaded connection end to rotate via the manual rotating part, the spike is located in the operating slot, and the other end of the threaded connection end is fixedly installed with a manual rotating part, which is located on the outside of the can lid.

[0009] Preferably, in order to facilitate operation of the manual rotating part, the manual rotating part is provided with a second anti-slip texture.

[0010] Preferably, to facilitate the use of the operating slot, the operating slot is arranged along the radial direction of the can lid, with the slot opening facing outwards.

[0011] The beneficial effects of this utility model are as follows: When it is necessary to consume the food inside the can, the can lid needs to be opened first. When opening the can lid, the operator can directly rotate the can lid by hand. The surface of the can lid is provided with a first anti-slip texture, which increases the friction between the hand and the can lid and reduces the resistance to opening the lid. In addition, the can lid is thickened and the surface is flat without protruding edges, which effectively avoids the pressure and friction on the palm when holding it. If it is difficult to open by hand, the external rod can be inserted into the operating slot. The operating slot is used as a fulcrum to drive the can lid to rotate. The lever principle is used to apply force, so as to open the can lid with less effort. After opening the can lid, the sealing film can be cut through by the film-cutting component, and then the food inside the can can be consumed. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] As shown in the figure, this embodiment provides a fish can that is easy to open, including a can body 1 with an upward opening and an internal cavity. A sealing film 2 is sealed to the opening of the can body 1. A can lid 3 with a downward opening is threaded to the top of the can body 1 in the vertical direction. The can lid 3 extends outward in the vertical direction to form a thickened area 4. An operation slot 5 is provided on the thickened area 4. A film-cutting component 6 for cutting open the sealing film 2 is provided in the operation slot 5. The outer wall of the can lid 3 is provided with a first anti-slip texture in a circumferential array. The operation slot 5 is arranged in the radial direction of the can lid 3 with the slot facing outward. The can lid 3 is thickened and has a flat surface without protruding edges, which effectively avoids pressure and friction on the palm when holding it. The sealing film 2 can isolate air and moisture, prevent the fish meat from oxidizing and deteriorating, prevent microbial invasion, increase the sealing effect, and ensure quality and safety.

[0020] When a user needs to eat canned fish, the operator can first use the first anti-slip texture array on the outer circumference of the can lid 3 to rotate the can lid 3 by hand. The anti-slip texture significantly increases the friction between the hand and the can lid 3. Combined with the increased grip stability of the thickened area 4 of the can lid 3, it reduces the difficulty of opening by hand. If it is still difficult to open by hand, the user can choose a thin rod-shaped tool such as chopsticks and insert it radially into the operation slot 5 along the can lid 3. Since the opening of the operation slot 5 faces outward, the tool naturally forms a lever structure after insertion. The user applies force with the operation slot 5 as the fulcrum. Through the force-saving characteristics of the lever principle, only a small torque is needed to rotate and open the can lid 3 without the need for professional can-opening tools. In addition, before inserting the thin rod-shaped tool into the operation slot 5, the user can first rotate the film-cutting component 6 to remove it. After the film-cutting component 6 is removed, the operation slot 5 can be exposed for subsequent operations.

[0021] An internal thread is provided on one end of the operating slot 5, and the film-cutting assembly 6 can be connected to the operating slot 5 through the engagement of the internal thread.

[0022] The film-splitting assembly 6 includes a threaded connection end 601, which is threaded onto the internal thread of one end of the operating slot 5. One end of the threaded connection end 601 is provided with a spike 602, which is located inside the operating slot 5. A manual rotating part 603 is fixedly installed on the other end of the threaded connection end 601. The manual rotating part 603 is located on the outside of the can lid 3 and is provided with a second anti-slip texture. Before opening the can lid 3, if the sealing film 2 is tightly stuck and affects opening, the user can remove the film-splitting assembly 6 from the can lid 3. The film-splitting assembly 6 includes a manual rotating part 603, a threaded connection end 601, and a spike 602. After removal, the user can hold the manual rotating part 603 with their hand and then insert the spike 602 into the sealing film 2. When the spike 602 moves, the sealing film 2 can be split open, and then the food inside the can can be eaten.
