Description

Technical Field

[0001] This utility model relates to the field of food container technology, specifically a portable insulated container. Background Technology

[0002] Insulated containers are used to hold soups and beverages, and generally consist of a container body and a lid. Existing insulated containers often use a multi-threaded connection between the lid and body for sealing, which has drawbacks such as difficulty in disassembly and assembly, difficulty in cleaning the sealing ring, poor sealing performance, or difficulty in opening the lid due to vacuum suction. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a portable insulated container with a simple structure, easy disassembly and cleaning, good sealing performance, and the ability to effectively avoid the problem of difficulty in opening the lid due to vacuum adsorption.

[0004] This utility model is achieved through the following technical solution: A portable insulated container includes a container body and a lid. The lid has a downwardly protruding, tapering conical sealing inner lid. At least one of the outer circumferential wall of the container body and the inner circumferential wall of the lid has at least two spaced arc-shaped protrusions, and the other has a corresponding protrusion that engages with the protrusions. The protrusions are inclined vertically. The lid and the container body can be fixedly connected by the engagement of the protrusions and the protrusions. When the lid and the container body are fixedly connected, the opening of the container body can press against the outer circumferential wall of the sealing inner lid to achieve a seal.

[0005] As a preferred technical solution, the outer circumferential wall of the sealing inner cover is also provided with a detachable sealing ring. When the can cover and the can body are fixedly connected, the can opening of the can body can be pressed against the sealing ring to achieve a seal.

[0006] As a preferred technical solution, the sealing ring is provided with a downwardly protruding ear structure, the lower end of which protrudes to the lower end face of the sealing inner cover.

[0007] As a preferred technical solution, the end of the protrusion is further provided with a limiting block for blocking and limiting the protrusion.

[0008] This utility model discloses a portable insulated container, which has the following beneficial effects: By providing a downwardly protruding, tapered conical sealing inner cover inside the lid, and at least one of the outer circumferential wall of the container body and the inner circumferential wall of the lid having at least two spaced arc-shaped protrusions, and the other having a corresponding protrusion that cooperates with the protrusions, the lid and container body can be tightly joined by a "vertical pressing + rotation locking" method. This is simple to operate and easy to disassemble and assemble, avoiding the problems of cumbersome disassembly and cleaning associated with traditional multi-threaded containers. Furthermore, the container opening presses against the outer circumferential wall of the sealing inner cover to achieve a seal, and a sealing ring is provided at the contact point, achieving efficient sealing and leak prevention. Moreover, when opening the lid, only a slight reverse rotation of the lid is needed to create a gap between the container opening and the outer circumferential wall of the sealing inner cover, effectively avoiding the problem of difficulty in opening the lid after a vacuum forms inside the container. This makes it particularly suitable for children and the elderly. By incorporating an ear-shaped structure, it facilitates quick disassembly, cleaning, and installation by users, solving the problem of traditional sealing rings being difficult to clean.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] like Figure 1-3 As shown, this embodiment discloses a portable insulated container, including a container body 31 and a lid 32. The lid 32 has a downwardly protruding, tapering conical sealing inner cover 321. The inner circumferential wall of the lid 32 and the outer circumferential wall of the container body 31 are respectively provided with four pairs of evenly spaced and mutually cooperating arc-shaped ridges 322 and protrusions 311. The ridges 322 are inclined vertically, and the protrusions 311 can be dot-shaped, block-shaped, or strip-shaped. In this embodiment, it is preferred that the protrusions 311 are strip-shaped structures that match the shape and inclination angle of the ridges 322. In use, when the ridges 322 and protrusions 311 are staggered... Press the can lid 32 vertically downwards so that the protrusion 311 is lower than the starting point of the ridge 322. Then rotate the can lid 32 at a certain angle (e.g., 90° in this embodiment) so that the protrusion 311 engages with the ridge 322, thereby achieving a fixed connection between the can lid 32 and the can body 31. When the can lid 32 and the can body 31 are fixedly connected, the can opening of the can body 31 can press against the outer circumferential wall of the sealing inner cover 321 to achieve a seal. Furthermore, preferably, the outer circumferential wall of the sealing inner cover 321 is also provided with a sealing ring 323. When the can lid 32 and the can body 31 are fixedly connected, the can opening of the can body 31 can press against the sealing ring 323 to achieve a seal. This design allows the lid 32 and body 31 of the insulated container 3 to be tightly joined by a "vertical press-in + rotation locking" method. It is simple to operate and easy to disassemble and assemble, avoiding the cumbersome disassembly and assembly problems of traditional multi-turn threads. The can body 31's opening presses against the outer circumferential wall of the sealing inner cover 321 to achieve a seal, and a sealing ring 323 is set at the contact point between the two to achieve efficient sealing and leak prevention. Moreover, when opening the lid, it is only necessary to slightly rotate the lid 32 in the opposite direction to create a gap between the can body 31's opening and the outer circumferential wall of the sealing inner cover 321. This effectively avoids the problem of difficulty in opening the lid after a vacuum is formed inside the can body 31, making it especially suitable for children and the elderly to operate.

[0014] As a preferred embodiment, the end of the protrusion 322 is also provided with a limiting block 3221 for blocking and limiting the protrusion 311. In use, when the bottle cap is rotated until the protrusion 311 hits the limiting block 3221, the can cap 32 and the can body 31 are fixedly connected and sealed.

[0015] In a preferred embodiment, the sealing ring 323 is a removable sealing ring, and the sealing ring 323 has a downwardly protruding ear structure 3231, the lower end of which protrudes to the lower end face of the sealing inner cover 321. This design facilitates quick disassembly, cleaning, and installation by the user, solving the problem of traditional sealing rings 323 being difficult to clean.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
