[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] Please see Figures 1-7 This utility model provides a finished product can with a gentle discharge, including a can body 1 and a can lid 2, both of which are made of tinplate. The top of the can body 1 is provided with a downward-bent hook 101, and the lower surface of the can lid 2 is provided with an upward-bent hook 201. The bent portion of the hook 201 is embedded in the hook 101, so that the hook 101 and the hook 201 cooperate to form a barbed structure, and the hook 101 and the hook 201 fit tightly together. Because the barbed structure is equivalent to having three or four pieces of tinplate, the structural strength at the connection between the can body 1 and the can lid 2 is high, which can withstand the load transmitted from the can lid 2, improving the overall stability of the finished product can.
[0024] It should be noted that the barbed structure is prepared through two processes: bending and pressing. When the finished can is used to store various liquid materials such as edible oil and water, food-grade sealant is pre-applied to the tinplate mating surfaces of the body hook 101 and the lid hook 201 before the barbed structure is prepared. During the pressing process, the tinplate and the food-grade sealant are tightly bonded, thus ensuring the sealing performance of the barbed structure and preventing leakage. When the finished can is used to store various solid materials such as coffee, cereal, and chili powder, it is not necessary to apply food-grade sealant to the mating surfaces of the body hook 101 and the lid hook 201.
[0025] Please see Figure 1 , Figure 3 , Figure 4 and Figure 7 The can lid 2 has a discharge port in the center of its upper surface. A screw nozzle 3 corresponding to the discharge port is installed on the can lid 2, and a screw cap 4 is threaded onto the screw nozzle 3. A protruding snap-fit portion 202 is formed in the center of the upper surface of the can lid 2, surrounding the oil discharge port. The snap-fit portion 202 and the screw nozzle 3 are press-fitted together. The screw nozzle 3 is made of plastic. The screw nozzle 3 can be directly installed on the can lid 2 by pressing; compared to traditional tinplate screw nozzles 3, which require riveting to the can lid 2, the screw nozzle 3 of this application is easier to install. Because the screw nozzle 3 is made of plastic, it has a certain degree of elasticity, thus ensuring the sealing of the connection between the screw nozzle 3 and the snap-fit portion 202, effectively preventing leakage.
[0026] Please see Figure 2 The bottom of the screw cap 4 is connected to a tear strip 5. Several inwardly protruding movable blocks 501 are formed on the inner wall of the tear strip 5. Several outwardly protruding fixed blocks 301 are formed on the outer surface of the bottom of the screw tip 3. The movable blocks 501 are embedded between the fixed blocks 301. When the tear strip 5 is not torn off, the movable blocks 501 embedded between the fixed blocks 301 can prevent the screw cap 4 from rotating, thus avoiding accidental unscrewing of the screw cap 4. After the tear strip 5 is torn off, the screw cap 4 can be opened normally from the finished product can.
[0027] Please see Figure 2 and Figure 3 The screw nozzle 3 has a buffer structure 6 inside, which consists of an oil-blocking part 601 and a connecting part 602. The oil-blocking part 601 is located at the center of the screw nozzle 3 and is connected to the inner wall of the screw nozzle 3 through the connecting part 602, which is arranged in a ring array around the oil-blocking part 601. During the oil pouring operation in the finished product tank, the buffer structure 6 can buffer the flow, preventing excessive oil from flowing out at once, thus ensuring the smoothness of the pouring process and reducing potential waste caused by excessive oil flow.
