Description

Technical Field

[0001] This utility model relates to the field of canning technology, and in particular to a fish can with good sealing properties. Background Technology

[0002] Canned fish, made from fish as the core ingredient and refined through multiple processes including processing, canning, sealing, and sterilization, is highly favored by consumers and occupies a significant market share due to its advantages of easy storage, portability, and consumption. Currently, the cans used for canned fish packaging mainly fall into three categories: metal cans, glass jars, and flexible composite cans.

[0003] Metal cans, represented by tinplate cans, effectively resist external corrosion due to their high strength and excellent barrier properties, greatly extending product shelf life and facilitating transportation and storage. However, their opaque nature prevents consumers from directly observing the food inside, and the recycling process is complex, resulting in shortcomings in environmental protection and user experience. Glass jars, with their transparent material, clearly display the state of the food inside, are chemically stable, and reusable. However, their fragility leads to higher production and transportation costs and makes them unsuitable for packaging high-fat fish, limiting their application scenarios. Composite flexible cans, while lightweight, flexible, easy to heat, and available in various packaging forms, suffer from low strength and susceptibility to breakage, and consumer awareness of their safety needs further improvement.

[0004] In practical applications, the smooth surface of glass jars makes opening them extremely inconvenient, causing inconvenience to consumers. Furthermore, their fragile nature necessitates additional protective materials during transportation, increasing both space requirements and transportation costs. Moreover, the negative pressure generated inside the jars during processing further exacerbates the difficulty of opening, resulting in significant shortcomings in both ease of use and economical transportation of glass jars, which urgently require technological improvements to address.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] As shown in the figure, this embodiment provides a fish can with good sealing performance, including a glass jar body 1. Connecting blocks 2 are evenly designed at the lower end of the glass jar body 1. These blocks cooperate with connecting grooves 6 on the sealing cap 4 to achieve initial positioning and fixation between the glass jar body 1 and the sealing cap 4, enhancing the stability of the connection. Anti-slip connecting grooves are designed on the outer sides of both ends of the glass jar body 1. These grooves provide installation positions for protective connecting parts 3. The anti-slip design also increases the friction between the protective connecting parts 3 and the anti-slip grooves, ensuring that the protective connecting parts 3 are securely fitted onto the glass jar body 1. Protective connecting parts are fitted onto the outer sides of the anti-slip connecting grooves. 3. The function is to protect the glass jar 1. One end of the glass jar 1 is provided with a threaded sealing port. A sealing connecting cover 4 is installed on the outer thread of the threaded sealing port to seal the glass jar 1. The sealing connecting cover 4 is provided with a sealing adjustment structure 5 inside. The upper surface of the sealing connecting cover 4 is evenly provided with connecting grooves 6. The connecting block 2 slides and engages with the connecting groove 6, and slides and engages with the connecting block 2 at the lower end of the glass jar 1, further strengthening the connection between the glass jar 1 and the sealing connecting cover 4, making the connection between the two more secure, and preventing the sealing connecting cover 4 from accidentally falling off during opening or use.

[0025] The protective connector 3 includes an elastic collar 301 and connecting hook and loop fasteners 302. The inner side of the elastic collar 301 is uniformly designed with damping protrusions, which slide and engage with the anti-slip connecting grooves. The connecting hook and loop fasteners 302 are uniformly and fixedly installed around the elastic collar 301. The connecting hook and loop fasteners 302 include both fleece-faced and hook-faced fasteners. The fleece-faced fasteners are respectively located on adjacent sides of the elastic collar 301, and the hook-faced fasteners are located on the other two sides of the elastic collar 301. If the tank requires high fixation during transportation or storage, or if multiple tanks need to be combined, the connecting hook and loop fasteners 302 uniformly fixed around the elastic collar 301 can be used to bond the hook and loop fasteners of the elastic collar 301 on adjacent tanks together, making the connection between the tanks tighter and preventing collisions during movement. This further enhances the connection stability between the elastic collar 301 and the tank, ensuring the protective effect.

[0026] The outer surface of the sealing connection cover 4 is designed with anti-slip texture. The inner side of the sealing connection cover 4 is designed with a sealing ring 401. The sealing ring 401 slides and engages with the inside of the threaded sealing port. The outer side of the sealing ring 401 is designed with an annular positioning groove. The inside of the annular positioning groove slides and engages with an elastic sealing ring 402.

[0027] Pick up the sealing cap 4 and align it with the threaded sealing port of the glass jar 1. Due to the sliding engagement of the sealing ring 401 with the inside of the threaded sealing port and the positioning effect of the elastic sealing ring 402 in the annular positioning groove, the sealing cap 4 can accurately fit with the threaded sealing port. Then, by rotating the sealing cap 4, the sealing cap 4 is gradually tightened by using its external thread and the internal thread of the threaded sealing port. During the tightening process, the elastic sealing ring 402 is compressed, which plays a sealing role. At the same time, the anti-slip texture ensures that the hand can stably rotate the sealing cap 4 until the sealing cap 4 is completely tightened.

[0028] The sealing adjustment structure 5 includes a rotating adjustment plate 501. A rotating mounting groove is provided at the center of the sealing connection cover 4. The rotating adjustment plate 501 is rotatably engaged inside the rotating mounting groove. Vent holes are provided on both sides of the rotating mounting groove. Positioning mounting grooves are provided on the lower surfaces of both ends of the rotating adjustment plate 501. An arc-shaped elastic plug 502 is embedded inside the positioning mounting groove. The arc-shaped elastic plug 502 is tightly fitted with the inner surface of the vent hole. Damping transition grooves are provided on both sides of the rotating adjustment plate 501. A rotating operating plate 503 is rotatably installed inside the damping transition groove.

[0029] After the fish can is sealed, the rotating adjustment plate 501 is positioned so that the arc-shaped elastic plug 502 fits tightly against the vent hole. At this time, the vent hole is completely blocked, and the inside of the can is in a good sealed state, which can effectively prevent external air and moisture from entering the can and ensure the quality and shelf life of the fish can.

[0030] When the pressure inside the tank is abnormal or when pressure needs to be released before opening the tank, the operator holds the rotating control plate 503. The rotating control plate 503 drives the rotating adjustment plate 501 to rotate in the rotating mounting groove. The arc-shaped elastic plugs 502 at both ends of the rotating adjustment plate 501 move accordingly, gradually disengaging from the tight fit with the vent hole, so that the vent hole opens to a certain extent. At this time, the gas inside the tank can be discharged or enter through the vent hole, thereby adjusting the pressure or sealing degree inside the tank.

[0031] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
