Description
Technical Field
[0001] This utility model belongs to the field of cup technology, and in particular relates to a container. Background Technology
[0002] There is a container for drinking water, beverages and other liquids, which generally consists of a lid and a body. The top of the body has a spout, from which liquid can be poured into the body. Then the lid is placed on the spout to form a sealed space. When drinking, one can drink through the spout on the lid.
[0003] For this type of container, there are generally two ways to connect the lid and the body. One is a threaded connection between the lid and the body. However, this method usually requires rotating the lid many times when installing or removing it, making it inconvenient. The other method involves a sealing rubber ring on the outer wall of the lid. The lid is directly pressed onto the body, and the sealing rubber ring is squeezed. The friction between the sealing rubber ring and the inner wall of the body allows the lid and body to be installed. However, in this method, the sealing rubber ring, in addition to its sealing function, also needs to connect the lid and the body. This connection requires significant friction between the sealing rubber ring and the inner wall of the body. This high friction means that a lot of force is needed to press the lid into the body, making it inconvenient to operate. Utility Model Content

[0005] The inner cavity of the cup body is provided with several limiting protrusions;
[0006] The cup lid includes a connected lid top and a screw-in ring. The screw-in ring is provided with screw-in trajectory grooves that correspond one-to-one with the limiting protrusions.

[0009] The inner wall of the screw-in track groove includes a positioning surface corresponding to the end positioning section, and the step surface is the positioning surface or the step surface is a part of the positioning surface; from the middle guide section to the end of the screw-in track groove away from the initial opening section, the step surface is configured to extend in a direction away from the top of the cover.
[0010] The guide surface and the positioning surface are connected and cooperate to form the preset limiting step;
[0011] Furthermore, both the guide surface and the positioning surface are oriented towards the top of the cover.
[0012] Optionally, the positioning surface includes the stepped surface and the limiting surface, with both ends of the stepped surface connected to the guide surface and the limiting surface, respectively;
[0013] The limiting surface extends from the end of the stepped surface away from the initial opening segment of the screw-in track groove, and extends to the top of the cover; the limiting surface is used to restrict the movement of the limiting protrusion away from the intermediate guide segment, and the limiting surface and the stepped surface cooperate for the positioning of the limiting protrusion.
[0014] Optionally, the positioning surface is an arc surface.
[0015] Optionally, the surface of the limiting protrusion facing away from the top of the cover is a smooth curved surface.
[0016] Optionally, the inner wall of the screw-in track groove further includes a second guide surface corresponding to the intermediate guide section, the second guide surface being arranged in a direction away from the top of the cover;
[0017] In one of the directions of the circumferential direction of the screw-in ring, both the guide surface and the second guide surface in the same screw-in trajectory groove extend toward the top of the cover.
[0018] Optionally, the distance between any two points on the surface of the limiting protrusion is defined as the first distance; the spacing between the guide surface and the second guide surface is greater than the maximum first distance.
[0019] Optionally, the inner wall of the screw-in track groove includes two guide surfaces and two stepped surfaces; in one of the directions of the circumferential direction of the screw-in ring, one of the two guide surfaces in the same screw-in track groove extends toward the top of the cover, and the other extends away from the top of the cover.

[0023] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:
[0024] The container provided by this utility model has a lid that, during the rotational installation process from the initial opening section into the screw-in track groove, passes through the intermediate guide section, and finally enters the end positioning section. After the limiting protrusion enters the end positioning section through the preset limiting step, due to the restriction of the step surface, the lid will not retract relative to the cup body (without applying external force), thus completing the installation of the lid onto the cup body. When it is necessary to remove the lid from the cup body, forcefully rotate the lid in the opposite direction to allow the limiting protrusion to pass through the preset limiting step into the intermediate guide section, and finally, rotate in the opposite direction to remove the lid from the cup body.
[0025] The container provided by this utility model, during the rotation process of the cup lid being installed onto the cup body, allows the limiting protrusion to move within the intermediate guide section. The intermediate guide section, extending towards the top of the lid, guides the lid towards the cup body with the cooperation of the corresponding limiting protrusion, thus making the installation of the lid easier (compared to the direct pressing method in existing technologies). Furthermore, the entire process of installing the lid onto the cup body does not require much rotation; only a small rotation is needed to complete the installation, making the process simple and quick. Moreover, the preset limiting step provides feedback to the operator when the lid and cup body are properly installed (i.e., when the limiting protrusion passes through the preset limiting step and enters the final positioning section), allowing the operator to know that the lid and cup body are correctly installed.

In this document, "one" not only means "only one," but can also mean "more than one."
[0037] Example 1
[0038] See Figures 1 to 6This embodiment provides a container, including a cup body 2 and a cup lid 1. The inner cavity of the cup body 2 is provided with a plurality of limiting protrusions 3. The cup lid 1 includes a connected lid top 4 and a screw-in ring 5, and the screw-in ring 5 is provided with screw-in trajectory grooves 6 corresponding one-to-one with the limiting protrusions 3. The screw-in trajectory of the screw-in trajectory groove 6 includes an initial opening segment 7, an intermediate guide segment 8, and an end positioning segment 9 connected in sequence. The initial opening segment 7 is configured to have a through opening extending to the lower end face of the screw-in ring 5; from the initial opening segment 7 to the end positioning segment 9, the intermediate guide segment 8 is configured to extend towards the lid top 4; the end positioning segment 9 is configured to cooperate with the intermediate guide segment 8 to form a preset limiting step 10, the step surface 13 of the preset limiting step 10 being used to limit the movement of the limiting protrusions 3 towards the intermediate guide segment 8.
[0039] During the process of rotating the lid 1 onto the cup body 2, the limiting protrusion 3 enters the screw-in track groove 6 from the initial opening section 7, passes through the intermediate guide section 8, and finally enters the end positioning section 9. After the limiting protrusion 3 enters the end positioning section 9 through the preset limiting step 10, due to the restriction of the step surface 13 of the preset limiting step 10, the lid 1 will no longer retract relative to the cup body 2 (without applying external force), thus completing the action of installing the lid 1 onto the cup body 2. When it is necessary to remove the lid 1 from the cup body 2, forcefully rotate the lid 1 in the opposite direction, so that the limiting protrusion 3 can enter the intermediate guide section 8 through the preset limiting step 10, and finally, by rotating in the opposite direction, the lid 1 can be removed from the cup body 2.
[0040] The container in this embodiment will be further described below.
[0041] The cup body 2 has a spout at its top, which connects to the inner cavity of the cup body 2 (i.e., the spout is the opening of the inner cavity of the cup body 2). When the lid 1 is installed on the cup body 2, the screw-in ring 5 on the lid 1 extends into the opening. The screw-in ring 5 also has a sealing ring 16, the inner side of which fits against the outer wall of the screw-in ring 5. When the lid 1 is installed on the cup body 2, the outer side of the sealing ring 16 is pressed tightly against the inner wall of the inner cavity of the cup body 2, thereby achieving a seal between the lid 1 and the cup body 2. Specifically, the sealing ring 16 is located on the side of the screw-in groove 6 facing the lid 1.
[0042] The inner wall of the screw-in groove 6 includes a guide surface 11 corresponding to the intermediate guide section 8; from the initial opening section 7 to the final positioning section 9, the guide surface 11 is configured to extend towards the top cover 4. The inner wall of the screw-in groove 6 includes a positioning surface 12 corresponding to the final positioning section 9, and a stepped surface 13 is either the positioning surface 12 or a part of the positioning surface 12; from the intermediate guide section 8 towards the end of the screw-in groove 6 away from the initial opening section 7, the stepped surface 13 is configured to extend away from the top cover 4. The guide surface 11 and the positioning surface 12 are connected and cooperate to form a preset limiting step 10. Both the guide surface 11 and the positioning surface 12 are oriented towards the top cover 4.
[0043] Thus, when the cup lid 1 is rotated onto the cup body 2, and the limiting protrusion 3 is in the middle guide section 8, the cup lid 1 rotates relative to the cup body 2, causing the limiting protrusion 3 to abut against the guide surface 11. Then, when it continues to rotate, the cooperation between the limiting protrusion 3 and the guide surface 11 will convert the rotational force applied by the operator into a force that drives the cup lid 1 to move towards the cup body 2, thereby making it easier to install the cup lid 1 onto the cup body 2.
[0044] Specifically, in this embodiment, the positioning surface 12 includes a stepped surface 13 and a limiting surface 14. The two ends of the stepped surface 13 are connected to the guide surface 11 and the limiting surface 14, respectively. The limiting surface 14 extends from the stepped surface 13 toward the end of the screw-in track groove 6 away from the initial opening segment 7, and extends toward the top of the cover 4. The limiting surface 14 is used to restrict the movement of the limiting protrusion 3 away from the intermediate guide segment 8. The limiting surface 14 and the stepped surface 13 cooperate to position the limiting protrusion 3. Preferably, the positioning surface 12 is an arc surface.
[0045] The surface of the limiting protrusion 3 facing away from the top of the lid 4 is a smooth curved surface. During the process of rotating the lid 1 onto the cup body 2, the surface of the limiting protrusion 3 facing away from the top of the lid 4 will abut against the guide surface 11 and slide relative to the guide surface 11. Its smooth curved surface design makes the sliding of the limiting protrusion 3 and the guide surface 11 smoother and less effort.
[0046] The inner wall of the screw-in groove 6 also includes a second guide surface 15 corresponding to the intermediate guide section 8, and the second guide surface 15 is oriented away from the top cover 4; wherein, in one of the directions of the circumference of the screw-in ring 5, both the guide surface 11 and the second guide surface 15 in the same screw-in groove 6 extend towards the top cover 4. The distance between any two points on the surface of the limiting protrusion 3 is defined as the first distance; the distance between the guide surface 11 and the second guide surface 15 is greater than the maximum first distance.
[0047] Thus, when the cup lid 1 is rotated in the opposite direction (relative to the direction of rotation of the cup lid 1 when it is to be installed on the cup body 2) to remove the cup lid 1 from the cup body 2, the limiting protrusion 3 is in the middle guide section 8. When the cup lid 1 rotates in the opposite direction relative to the cup body 2, the limiting protrusion 3 abuts against the second guide surface 15. Then, when the reverse rotation continues, the cooperation between the limiting protrusion 3 and the second guide surface 15 will convert the reverse rotation force applied by the operator into a force that moves the cup lid 1 away from the cup body 2, thereby making it easier to remove the cup lid 1 from the cup body 2.
[0048] Preferably, the entire outer surface of the limiting protrusion 3 can be made into a smooth curved surface, thereby facilitating sliding with the guide surface 11 or the second guide surface 15.
[0049] The inner cavity of the cup body 2 is provided with at least three limiting protrusions 3, which are evenly distributed around the circumference. This design allows the cup lid 1 to be subjected to more balanced force during the process of rotating the cup lid 1 onto the cup body 2 and during the process of rotating the cup lid 1 in the opposite direction to remove it from the cup body 2, making it less likely for one side of the cup lid 1 to lift up.
[0050] Example 2
[0051] See Figures 6 to 10 This embodiment provides a container based on Embodiment 1. In this embodiment, the inner wall of the screw-in track groove 6 does not have the second guide surface 15 as in Embodiment 1.
[0052] In this embodiment, the inner wall of the screw-in groove 6 includes two guide surfaces 11 and two stepped surfaces 13. In one direction of the circumference of the screw-in ring 5, one of the two guide surfaces 11 in the same screw-in groove 6 extends towards the top cover 4, and the other extends away from the top cover 4. The two guide surfaces 11 and the two stepped surfaces 13 in the same screw-in groove 6 correspond one-to-one, and the guide surfaces 11 cooperate with the corresponding positioning surfaces 12 to form a preset limiting step 10.
[0053] Specifically, the inner wall of the spiral track groove 6 includes two positioning surfaces 12 corresponding to the end positioning segment 9, and the two stepped surfaces 13 are each part of the two positioning surfaces 12. The two positioning surfaces 12 correspond one-to-one with the two guide surfaces 11, and the positioning surfaces 12 are connected to the end of the corresponding guide surfaces 11 near the end positioning segment 9.
[0054] Preferably, the two guide surfaces 11 and the two positioning surfaces 12 in the same screw-in track groove 6 are symmetrically arranged about the same symmetrical surface.
[0055] In Embodiment 1, the arrangement of a guide surface 11 and a second guide surface 15 in the screw-in track groove 6 ensures that, in the circumferential rotational direction of the lid 1, one rotational direction is used to install the lid 1 onto the cup body 2, and the other rotational direction is used to remove the lid 1 from the cup body 2. In this embodiment, the arrangement of two guide surfaces 11 in the screw-in track groove 6 ensures that, in the circumferential rotational direction of the lid 1, both rotational directions are used to install the lid 1 onto the cup body 2. Thus, regardless of which direction the operator rotates the lid 1, it can be installed onto the cup body 2.
[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
