Description

Technical Field

[0001] The present disclosure relates to the technical field of containers, and in particular to a connection structure and a water bottle. Background Art

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The convex rib is an important structure at the mouth of the water bottle. Its clamping with the bottle cap can not only play a sealing effect, but also make the structure at the mouth of the bottle more stable, prevent the bottle cap from loosening or accidentally opening, and also increase the strength of the bottle mouth, improve the overall impact resistance and durability of the bottle. The bottle body formed by blow molding through the blow molding process has a smooth inner wall, but due to process limitations, only convex ribs can be formed on the outer periphery of the bottle mouth during the blow molding process, and functional convex ribs cannot be formed on the inner wall of the bottle body. The convex ribs formed outside the bottle mouth and connected with the bottle cap cannot play a good sealing effect, and cannot be used for bottle caps with other functions, thereby limiting the use function of the water bottle; and the convex ribs formed outside the bottle mouth will also affect the user's use, which is not ergonomic and affects the user's sense of use.

DETAILED DESCRIPTION

[0025] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0026] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 to Figure 3 As shown, a connection structure of an exemplary embodiment of the present disclosure includes an inner wall 1 and an outer wall 2 relative to each other. The inner wall 1 encloses a channel 10 for circulation. A limiting portion 11 and a first connection are provided on the inner wall 1. The limiting portion 11 is used to engage the cover body, and the first connection portion 12 is used to connect to the container mouth of the container.

[0028] In this embodiment, the connection structure is used to be arranged at the container mouth of an existing container, so that the container can be equipped with a cover body with different functions. The container can specifically include but is not limited to a water bottle, a water cup or a wine barrel, etc. The inner wall 1 of the connection structure encloses a channel 10 for liquid or solid circulation. Among them, the cover body can specifically include but is not limited to a structure with a push-button structure, a quick-opening structure or a structure with a straw, etc. These covers can be arranged on the container by engaging with the limiting part 11 of the connection structure to limit the position, so that the container has corresponding functions. The limiting part 11 is a convex rib protruding relative to the inner wall 1 or a groove recessed relative to the inner wall 1. In the embodiments shown in the present disclosure, the limiting part 11 is an example of a convex rib. When the connection structure is arranged at the container mouth, the user's mouth drinks water from the connection structure. Since the limiting part 11 is arranged inside the connection structure, it will not affect the user's drinking water, which is ergonomic. The first connection part 12 can be, but is not limited to, a threaded structure, which can be tightly connected to the container mouth. Therefore, the connection structure of the present invention has a limiting portion 11 for engaging the cover body on the inner wall 1, and the first connecting portion 12 can be connected to the container mouth of the container, so that various functional covers can be engaged with the limiting portion 11 and arranged on the connection structure, so that the container has corresponding functions, eliminating restrictions on the use function of the container; and because the limiting portion 11 is arranged inside the connection structure, it can increase the user's experience when using it, is ergonomic, and the connection structure is highly adaptable and can be added to different containers.

[0029] In one possible implementation manner, the limiting portion 11 protrudes toward the center of the connecting structure relative to the inner wall 1 .

[0030] Specifically, in one embodiment, the limiting portions 11 are continuously arranged along the circumference of the inner wall 1 .

[0031] In this embodiment, the limiting portion 11 is a convex rib. By providing the convex rib, the structure is made more stable, and the cover body stuck therewith is prevented from loosening or accidentally opening. In particular, for containers containing gas or liquid, a firm cover body can effectively prevent leakage or overflow of substances. The convex rib fits tightly with the cover body to form an effective seal, which can prevent the entry of air, moisture or other foreign substances and maintain the freshness and quality of the substances in the container. In addition, the convex rib can also increase the strength of the connection structure, improve the impact resistance and durability of the overall structure, which is very important for the protection of the container during transportation and storage. The convex rib is continuously arranged along the circumference of the inner wall 1, that is, it is arranged in an annular structure, the structure is stable, and the effect is good.

[0032] In one embodiment, there are multiple limiting portions 11 , and two adjacent limiting portions 11 are arranged at a certain distance along the circumference of the inner wall 1 .

[0033] In this embodiment, there may be multiple convex ribs, that is, the annular structure is discontinuous. This structure can save costs and also stabilize the structure and prevent the cover from loosening.

[0034] In one embodiment, the connection structure has a first port 101 and a second port 102 opposite to each other. The first port 101 and the second port 102 meet the parallel condition. The limiting portion 11 is disposed close to the first port 101 , and the first connection portion 12 is disposed close to the second port 102 .

[0035] Further, in one possible implementation manner, the limiting portion 11 and the first port 101 meet a parallel condition.

[0036] In this embodiment, the cover can be engaged or fastened with the first port 101, and the second port 102 is connected to the container mouth. When the connection structure is arranged at the container mouth, the user drinks water from the first port 101. Since the limiter 11 is arranged inside the connection structure, it will not affect the user's drinking, which is ergonomic. Since the limiter 11 is a convex rib and has an annular structure, the annular structure is parallel to the first port 101 and the second port 102, the structure is stable and the effect is good.

[0037] In one embodiment, a second connection portion 21 for connecting with the cover body is provided on the outer wall 2 of the connection structure.

[0038] In this embodiment, the second connection portion 21 is located at the first port 101 of the connection structure. The second connection portion 21 can be a tapered structure, which can be embedded in the cover body; or, the second connection portion 21 can be a threaded structure, and accordingly, a threaded structure is also provided on the cover body so that the cover body and the connection structure can be securely connected.

[0039] In one embodiment, a first groove 22 is provided on the outer wall 2 of the connection structure, and the first groove 22 is used to accommodate part of the sealing member 5 .

[0040] In this embodiment, the first clamping groove 22 is a retreat groove for arranging the sealing member 5, which can further strengthen the seal between the container and the connection structure during connection.
