[Previous technology] Plastic cans that are generally used to contain packaging items are commonly known on the market as Baote cans. Such cans often have different structures due to different functional purposes, and most of the differences are in plastic. A structure in which a mouth of a can body is combined with a lid closing the mouth of the can body. At present, most of the combined structures are screwed on the outer peripheral surface of the can with the threads on the inner peripheral surface of the cap, or the cap is closed by means of a plug, but the airtight effect is poor. When filling liquids, substances such as enzyme lysate may leak juice from the lid and the tank, or foreign matter may seep between the lid and the tank and contaminate the contents of the tank. When the cap is closed by a cap to close the jar mouth, when the cap is pressed downward from above the mouth of the jar to be stuffed in the mouth of the jar, the milk inside the jar and the cap cannot escape. To make the top of the cover stricter upwards, so that consumers mistakenly believe that the contents of the cans have changed or become corrupted. [New content] The main purpose of this new model is to provide a can that can be air-tightly closed, so that the new can can hold and store liquid contents. Cans The secondary purpose of this new model is to provide a can that does not bulge on the top surface of the lid when the lid is plugged. This new type of tank includes ·· _ — 太 # 0 ^ ^ 5 tank body and a cap 20 M249919 for closing the tank body. The tank body has a bottom wall and a ridge extending upward from a peripheral edge of the bottom wall. The surrounding wall has a surrounding wall section extending from the bottom to the same body, a middle wall section with a smaller diameter than the lower wall section, and an upper wall with a larger diameter than the middle wall section. A ring-shaped cover frame, a cover sheet releasably closed in the cover frame, a ring groove forming the outer peripheral surface of the cover frame, and a sleeve enclosed in the ring groove and tightly abutting against it The loops between the inner peripheral surface of the wall section in the tank body. 10 The function of this new model can provide a can that can be hermetically closed to prevent the contents of the tank from leaking between the lid and the tank body, or Causes foreign objects to infiltrate and contaminate between the lid and the tank to achieve the perfect preservation of the contents. And to prevent the top of the lid from bulging upwards, avoiding consumers mistakenly thinking that the contents of the tank have changed or become corrupted. [Embodiment] 15 The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the drawings. Referring to FIGS. 1 and 2, A preferred embodiment of the novel can includes a can body 2 and a piece of the can A cover 3 on the body 2, an upper cover 4 covering the cover 3, and a plug rod 5 which is removably inserted between the tank body 2 and the cover 3 to facilitate exhausting during assembly. The tank body 2 has a circular bottom wall 21 and a surrounding wall 22 extending upwardly from a peripheral edge of the bottom wall 2. The bottom wall 21 and the surrounding wall 22 together define an upper open end 23 for receiving. A space for accommodating articles. The surrounding wall 22 has a lower surrounding wall section 22 and a middle surrounding wall section 222 extending from the top edge of the lower surrounding wall section 221 to 20 M249919 and having a smaller caliber than the lower surrounding wall section and 221. And a top wall section 223 extending upward from the top wall of the middle wall section 222 and having a diameter larger than that of the middle wall section 2 2 2 5 I seal 3 is enclosed in the tank body z & lt The upper open end 23 'has a ring-shaped cover frame 31,-a cover sheet 32 that can be detachably closed in the cover frame 31,-a pull ring 33 fixed to the top surface of the cover sheet 32,- A ring groove 34 is formed on the outer peripheral surface of the cover frame 31, and a washer 35 enclosing the ring groove 34 is formed. The gasket 35 is made of rubber material and has a ring shape. 10 The shape can also be— Length and circumference of the ring groove 34 The shape of the equal pass ring strip is not limited to the above. The cover frame 31 is plugged on the tank body 2 in the middle wall section 223, 15 222, and the ring groove 34 in the cover frame 31 is sheathed. The loop 35 is clamped against the inner peripheral surface of the inner wall section 222. The gasket 35 is used to keep the lid frame η and the inner wall J U22 hermetically sealed to prevent liquid contents in the tank body 2 Leakage or contamination of the contents outside the tank body 2 Poets inside the tank, to achieve the perfect preservation of the contents. When it is necessary to remove the contents for use, first open the upper cover 4 and then pull the pull ring 33 by external force, and The cover sheet 32 is torn away from the cover frame 31, and the contents can be taken out for use. The upper cover 4 has a horizontal base wall 41 and a base wall 41 extending downward from the periphery of the base wall 41 and tightly surrounding the cover frame 3 1 Surrounding wall outside the top edge. If the contents cannot be used up immediately after the cover sheet 32 is torn from the cover frame 31, and when it is necessary to continue storing, the upper cover 4 can be closed on the top edge of the cover frame 31 to close the can body 2 The open end 23 continues to keep the contents enclosed in the tank body 2. 20 M249919 5 Referring to FIG. I and FIG. 4, the plunger 5 is made of a flexible plastic material, and has-a drawing ring 51 for drawing,-under the drawing ring M & the tank body 2 The hook 53 extending obliquely downward from the wall 22 and two parallel rods extending downward from the edge of the extraction ring 5IJF to the surrounding wall 22 and parallel to each other ^ from 10 15 By this, when the tank body 2 is in the filling container After that, before the cover 3 is closed, the plunger 5 is clamped by the hook 53 on the top edge of the wall 22 of the tank body 2, the thin rods 54 project into the tank body 2 and the extraction ring η 4 Shen: Outside the tank body 2. When the cover 3 is inserted from the open end of the tank body 2 into the surrounding wall 22 and inserted into the surrounding wall 22, the insert rod 5 will be clamped between the surrounding wall 22 and the cover frame 31 and stretched. Make a gap so that the air originally in the tank body 2 and between the cover 3 escapes through the gap and the thin rods ^ doors. 'The cover 3 is plugged and positioned, and then the plug 5 is pulled out. The ring 51, ^ The plunger 5 is pulled out between the surrounding wall 22 and the cover frame 31, so that the cover 3 closes the open end 23 above the tank body 2 to achieve a sealing effect. To sum up, the above-mentioned can of the present type of can uses the arrangement of the gasket 35 to make the cover frame 31 and the surrounding wall section 222 of the surrounding wall 22 to maintain the airtight sealing effect of the can of the present type. When the container is filled and sealed, the plunger is used to extend between the surrounding wall 22 and the cover frame 31 to prevent the sealing piece 32 of the cover 20 3 from bulging upward after closing. So it can really achieve the purpose of this new model. However, the above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited in this way, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new application and the content of the new specification, All should still fall within the scope of this new patent. 7 M249919 [Brief description of the drawings] Figure 1 is an exploded perspective view of a preferred embodiment of the new type of tank.
