[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0027] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0028] Referring to 1-8, an embodiment of the utility model provides a composite sealed material storage tank, which includes a tank body 2 and a sealing cover 1 that penetrates into the tank body 2 and cooperates with the side wall of the tank body 2. The structural components of the sealing cover 1 include a first sealing portion 10 in a hollow ring shape, a second sealing portion 11 that is engaged at the bottom of the first sealing portion 10 to seal the opening position of the tank body 2, and a sealing component 13 that is sleeved on the circumference of the first sealing portion 10 and tightly fits therewith. When the sealing cover 1 penetrates into the tank body 2, the sealing component 13 arranged between the sealing cover 1 and the tank body 2 is gap-fitted between the sealing cover 1 and the tank body 2 in the opposite direction of the penetration direction of the sealing cover 1, so that an interference fit connection effect is generated between the sealing cover 1 and the tank body 2, and the packaging gap between the sealing cover 1 and the tank body 2 is filled.
[0029] The first sealing portion 10 includes a top edge 100, a latch groove 101, an inclined push surface 102 and a bottom edge 103 from top to bottom along its own height direction. Figure 6As shown in the figure, the bottom of the top edge 100 extends downward to form a latch groove 101 for embedding the sealing assembly 13, and the lower part of the latch groove 101 is radially contracted toward the axial direction of the first sealing part 10 to form an inclined push surface 102, and the lower part of the inclined push surface 102 is connected to the bottom edge 103, and the middle part of the bottom edge 103 is radially bent inward to form a convex eave 103-1, and the lower part of the bottom edge is connected to the second sealing part 11. The second sealing part 11 in the form of a disc is provided with a surrounding closed pre-cut notch 111 on its circumference, and the pre-cut notch 111 is arranged below the covering surface of the convex eave 103-1. A pull ring 110 is riveted toward the center of the circle on the pre-cut mark 111. When the pull ring 110 is pulled, the middle cover body is torn apart along the pre-cut mark 111 and separated from the side of the sealing cover 1. Since the broken part of the pre-cut mark 111 is covered by the convex eave 103-1, it is ensured that the user's hand will not touch the broken part when taking out the stored items in the can body, avoiding harm to the user at the broken part, thereby enhancing the safety of product use.
[0030] refer to Figure 7-8 As shown, the opening edge of the tank body 2 is bent inward to form a snap ring 20, and the inner diameter of the snap ring 20 should be not less than the outer diameter of the bottom of the inclined push surface 102 and not greater than the outer diameter of the top of the inclined push surface 102. Since the first sealing portion 10 and the second sealing portion 11 on the sealing cover 1 are integrally formed, pressing the second sealing portion 11 can make the sealing cover 1 slide along the inclined push surface 102 on the first sealing portion 10 toward the inside of the tank body 2 until the top of the inclined push surface 102 completely penetrates the tank body 2. At this time, the snap ring 20 on the tank body 2 enters the latch groove 101 of the sealing cover 1 and squeezes the sealing component 13. From the perspective of the matching relationship, the latch grooves 101 and the snap ring 20 at the two side positions are mutually embedded and squeeze the sealing component 13 at the middle position toward each other. The sealing component 13 is slightly deformed under the action of the lateral extrusion force and the axial friction force at the same time, and resists the snap ring 20 against the direction in which the snap ring 20 penetrates the latch groove 101.
[0031] The sealing component 13 described in this embodiment is a soft rubber ring, and the gap of the soft rubber ring is fitted between the latch groove 101 and the snap ring 20 to fill the assembly gap at the joint position of the sealing cover 1 and the tank body 2. Therefore, the use of the sealing cover 1 with a soft rubber ring of the utility model to seal the storage in the tank body 2 can not only produce a one-time embedded fixing effect by the sealing cover 1 and the tank body 2 to limit the sealing cover 1 and the tank body 2 to achieve the purpose of not being easily separated, but the use of the sealing component 13 can also enhance the sealing effect between the sealing cover 1 and the tank body 2 and increase the airtightness of the tank storage space. In other words, the storage tank of the utility model can not only encapsulate solid substances such as dried fruits and tea leaves, but also store liquid substances. At the same time, since the sealed tank provided by the embodiment of the utility model has a good airtight effect, when used to store food materials, the good airtight effect of the space in the tank can allow filling with inert gases such as nitrogen to extend the shelf life of the material, broaden the scope of use, and improve universality.
[0032] In addition, the sealing cover 1 described in the utility model is preferably made of light and soft aluminum, which can be easily processed and shaped and can be quickly manufactured. A soft rubber ring is nested on the sealing cover 1, and then quickly assembled with the tank body 2, which improves the performance of the product without increasing labor costs and operating procedures. The user can pull the pull ring 110 on the cover body 1 to separate the second sealing part 11 on the cover body 1 from the first sealing part 10 along the pre-cut mark 111, so that the user can directly take out the stored items in the tank body 2 from the hole without prying open the cover body as a whole, thereby improving the convenience of product use.
[0033] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
