Description

Technical Field

[0001] This utility model patent relates to the technical field of storage tanks, and more specifically, to a sealed tank. Background Technology

[0002] Sealed containers are a common type of container used in daily life, known for their excellent sealing properties. They are typically made of materials such as glass, plastic, or metal, and come in a variety of shapes.

[0003] The existing structure of sealed containers is too simple, usually consisting of a container body and a lid. The lid seals the opening of the container body, and the opening is integrally formed with the container body. Moreover, the opening is easily damaged and cannot be replaced. Once damaged, it will affect the sealing performance of the sealed container or directly cause the entire sealed container to be scrapped. It is not economical and causes some trouble for users during use. Utility Model Content

[0004] The purpose of this invention is to provide a sealed container that solves the problem that the opening of the sealed container is difficult to replace in the prior art.

[0005] This utility model is implemented as follows: a sealed container includes a container body, a connector, and a cover. The container body has an internal cavity, and the top of the container body has a can opening. The can opening includes a can mouth, which communicates with the cavity. The outer wall of the can opening is provided with an annular groove, and the connector is embedded in the annular groove. The cover seals the can opening and is detachably connected to the connector.

[0006] Furthermore, the outer side wall of the connector is provided with external threads, and the inner side wall of the cover is provided with internal threads, and the cover is threadedly connected to the connector.

[0007] Furthermore, the can opening has an upper flange, which is located above the annular groove.

[0008] Furthermore, the cover body includes a cover plate and a cover wall circumferentially disposed around the outer periphery of the cover plate, and the internal thread is disposed on the inner side wall of the cover wall; the cover plate has a limiting protrusion protruding in the direction toward the can opening, and when the cover body seals the can opening, the outer side wall of the limiting protrusion abuts against the inner side wall of the can opening.

[0009] Furthermore, the tank body includes a compressible telescopic portion located below the tank opening.

[0010] Furthermore, the telescopic part is lantern-shaped, with its center protruding outwards.

[0011] Furthermore, the telescopic part protrudes outward from the middle to form a plurality of spaced protrusions, and there are recesses between adjacent protrusions, which are arranged along the top to bottom direction of the tank.

[0012] Furthermore, the bottom of the tank is planar, and the thickness of the bottom of the tank is greater than the thickness of the telescopic part.

[0013] Furthermore, the container is transparent.

[0014] Compared with the prior art, the sealing container provided by this utility model realizes the opening or sealing of the sealing container through the detachable connection between the lid and the connector; by separating the connector at the can opening from the can body, the connector can be replaced when it is damaged, avoiding the waste caused by the entire sealing container being scrapped due to the damage of the connector.

[0021] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0022] A sealed container includes a container body 100, a connector 200, and a lid 300. The container body 100 has an internal cavity that can be used to hold liquids, colloids, small particulate solids, etc. The top of the container body 100 has a can opening, which includes a can opening 111 that communicates with the cavity, allowing objects to be placed into or removed from the cavity through the can opening 111. The outer wall of the can opening is provided with an annular groove 110, and the connector 200 is embedded in the annular groove 110. The lid 300 covers the can opening 111 and is detachably connected to the connector 200.

[0023] This embodiment provides a sealed container, which can be opened or closed by a detachable connection between the lid 300 and the connector 200. By separating the connector 200 at the container opening from the container body 100, the connector 200 can be replaced when it is damaged, thus avoiding waste caused by the entire sealed container being scrapped due to damage to the connector 200.

[0024] Since the connector 200 and the can 100 are not integrally formed, they can be made of different materials. For example, the connector 200 can be made of hard plastic, which makes it less prone to deformation and ensures a more stable connection between the connector 200 and the lid 300. The can 100 can be made of plastic or silicone material with a certain degree of elasticity, which facilitates sealing the can and also makes it easier to squeeze the can 100, allowing the contents of the can 100 to be easily squeezed out.

[0025] Specifically, the tank body 100 is transparent and made of transparent material, allowing users to directly observe the contents of the container.

[0026] Furthermore, the lid 300 and the connector 200 can be made of the same material, such as hard plastic. The container 100 can be made of transparent soft plastic, which can be compressed and squeezed, and also allows the user to see the contents of the container 100.

[0027] Specifically, the outer side wall of the connector 200 is provided with external threads, and the inner side wall of the cover 300 is provided with internal threads. The cover 300 is threadedly connected to the connector 200, which facilitates sealing of the sealed container.

[0028] The can opening has an upper flange 112, which is located above the annular groove 110. When the lid 300 is screwed on the connector 200, the top of the upper flange 112 abuts against the lid 300, and the upper flange 112 is compressed, further improving the sealing effect.

[0029] Specifically, the cover 300 includes a cover plate 310 and a cover wall 320 circumferentially disposed around the cover plate 310, with internal threads on the inner sidewall of the cover wall 320. The cover plate 310 has a limiting protrusion 311 protruding in the direction towards the can opening 111. When the cover 300 seals the can opening 111, the outer sidewall of the limiting protrusion 311 abuts against the inner sidewall of the can opening. By the limiting protrusion abutting against the inner sidewall of the can opening, the upper flange 112 will not detach from the connector 200 due to compression, making the seal of the sealed can more secure and reliable.

[0030] Furthermore, the can body 100 includes a compressible telescopic portion 120 located below the can opening. This means the can body 100 can be compressed, facilitating the expulsion of objects from its cavity.

[0031] The telescopic part 120 is lantern-shaped, with its center protruding outwards, allowing the cavity to hold more objects and making it easier for the user to squeeze the telescopic part 120.

[0032] The telescopic part 120 protrudes outward from the middle to form a plurality of spaced protrusions 121. There is a recess 122 between adjacent protrusions 121. The recesses 122 are arranged along the top to bottom direction of the can body 100, which makes it convenient for the user to squeeze the protrusions 121. Moreover, the adjacent arrangement of the recesses 122 and the protrusions 121 makes it easier for the squeezed protrusions 121 to spring back to the protruding state.

[0033] The bottom of the can 100 is flat, which makes it easy to place the sealed can stably. The thickness of the bottom of the can 100 is greater than the thickness of the telescopic part 120. The thicker bottom makes the can easy to place stably and makes the can more easily rebound after being squeezed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
