Description

Technical Field

[0001] This application relates to the field of container lid technology, and in particular to a lid structure and container. Background Technology

[0002] The lid structure is mainly used as a sealing structure for the body of cups, kettles, thermos cups, etc., and usually consists of an outer lid and an inner lid. However, most existing lid structures are assembled by pressing the outer lid and the inner lid together. Because the outer lid has a pattern, even if glue is applied to its inner wall, the outer lid cannot be completely glued and tightly connected to the inner lid, causing the lid structure to detach from the inner lid during use. Utility Model Content

[0003] Therefore, it is necessary to provide a lid structure and container with a more stable and secure connection between the inner and outer lids.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] A cover structure comprising:

[0006] The inner cover has a receiving cavity on one side;

[0007] A connector is disposed within the accommodating cavity and is detachably connected to the inner wall of the accommodating cavity;

[0008] An outer cover is fitted over the inner cover so that the inner cover is housed within the outer cover, and the outer cover is welded to the connector.

[0009] Understandably, this application achieves the connection between the inner and outer covers by setting up connectors and utilizing a detachable connection between the connectors and the inner cover, as well as a welding connection between the connectors and the outer cover. The welding connection effectively ensures the stability between the outer and inner covers and provides higher connection strength compared to pressing and gluing methods, enabling it to withstand greater mechanical stress. Thus, the outer cover will not detach from the inner cover during use, improving the user experience.

[0010] In one embodiment, the connector is snapped into place with the inner wall of the accommodating cavity via a snap-fit ​​structure.

[0011] In one embodiment, multiple snap-fit ​​structures are provided, and the multiple snap-fit ​​structures are spaced apart circumferentially along the receiving cavity.

[0012] Understandably, setting multiple snap-fit ​​structures can strengthen the connection between the connector and the inner cover, making the assembly structure between the two more stable.

[0013] In one embodiment, the snap-fit ​​structure includes an elastic snap-fit ​​arm and a snap-fit ​​groove, wherein one of the elastic snap-fit ​​arm and the snap-fit ​​groove is provided with an inner wall of a receiving cavity, and the other is provided with an outer wall of the connector;

[0014] When the connector is inserted into the receiving cavity, the elastic locking arm engages with the locking slot.

[0015] In one embodiment, the slot includes a first slot wall and a second slot wall, the first slot wall being connected to the second slot wall and being set at an angle;

[0016] The elastic locking arm has a first contact surface and a second contact surface, wherein the first contact surface is matched with the first groove wall and the second contact surface is matched with the second groove wall;

[0017] When the elastic locking arm is engaged in the slot, the first contact surface is in contact with the first slot wall, and the second contact surface is in contact with the second slot wall.

[0018] Understandably, this design allows for two angular connection limits between the connector and the inner cover, while also increasing the contact area between them, thus increasing the friction between them and effectively improving the stability of the connection between the connector and the inner cover.

[0019] In one embodiment, the inner wall of the accommodating cavity is provided with an anti-rotation part, and the connector is provided with an anti-rotation notch. The anti-rotation part and the anti-rotation notch can be circumferentially limited and engaged in the accommodating cavity.

[0020] It is understandable that an anti-rotation part is provided on the inner wall of the accommodating cavity, and an anti-rotation notch is made on the connector to cooperate with the anti-rotation part, so as to prevent the connector from separating from the inner cover when the cover structure makes circumferential rotation, thereby further improving the stability of the assembly of the connector and the inner cover.

[0021] In one embodiment, a guide portion is provided at one end of the anti-rotation portion facing the outer cover, the guide portion being used to guide the anti-rotation portion to engage with the anti-rotation notch.

[0022] Understandably, the guide section has a guiding function, which can guide the anti-rotation notch to align with the anti-rotation section when assembling the connector and the inner cover, making the assembly more precise and reliable.

[0023] In one embodiment, the inner cover is configured as a plastic part, and the connector and the outer cover are configured as metal parts; and / or, the side of the connector facing away from the accommodating cavity is provided with an energy storage solder joint.

[0024] Understandably, by setting up energy storage welding points, the connector and the outer cover are welded together using energy storage welding. In this way, by taking advantage of the extremely small heat-affected zone and high strength of energy storage welding, not only is thermal damage to the connector and the outer cover reduced, as well as welding defects such as welding deformation and cracks, but the connection strength between the connector and the outer cover is also improved.

[0025] In one embodiment, the cover structure further includes insulating foam embedded in the receiving cavity and extending into the connector.

[0026] It is understandable that insulating foam has a heat insulation function. Placing insulating foam between the inner cover and the connector can give the cover structure a heat insulation effect, thereby increasing the scope of application of the cover structure.

[0027] This application also provides the following technical solutions:

[0028] A container comprising the lid structure described in any of the above embodiments.

[0029] Compared to existing technologies, the described lid structure and container achieve the connection between the inner and outer lids by incorporating connectors and utilizing a detachable connection between the connectors and the inner lid, as well as a welding connection between the connectors and the outer lid. The welding connection effectively ensures the stability between the inner and outer lids and provides higher connection strength compared to pressing and gluing methods, enabling it to withstand greater mechanical stress. Thus, the outer lid will not detach from the inner lid during use, improving the user experience. Attached Figure Description

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0042] Please see Figures 1 to 4 This application provides a lid structure 100, which is applied to the opening of containers such as cups and jugs, and is mainly used to seal the opening of the container. Of course, the lid structure 100 is not limited to containers such as cups and jugs, and can also be applied to the opening of other containers, which is not limited here.

[0043] Specifically, the cover structure 100 includes an inner cover 10, a connector 20, and an outer cover 30. The inner cover 10 has a receiving cavity 11 on one side. The connector 20 is located within the receiving cavity 11 and is detachably connected to the inner wall of the receiving cavity 11. The outer cover 30 covers the inner cover 10, so that the inner cover 10 is housed within the outer cover 30, and the outer cover 30 is welded to the connector 20. It should be explained that in existing cover structures 100, the outer cover 30 and the inner cover 10 are assembled by press-fitting. To maintain the connection, adhesive is usually applied between the outer cover 30 and the inner cover 10. However, because the outer cover 30 has a pattern and the outer cover 30 and the inner cover 10 are made of different materials, the outer cover 30 and the inner cover 10 of such a cover structure 100 will still separate during use, resulting in unstable assembly. This application achieves the connection between the inner cover 10 and the outer cover 30 by setting a connector 20 and using a detachable connection between the connector 20 and the inner cover 10, as well as a welding connection between the connector 20 and the outer cover 30. The welding connection effectively ensures the stability between the outer cover 30 and the inner cover 10, and provides a higher connection strength compared to pressing and gluing methods, capable of withstanding greater mechanical stress. Thus, the outer cover 30 will not detach from the inner cover 10 during use, thereby improving the user experience.

[0044] Here, the inner cover 10 is configured as a plastic part. It is understood that plastic parts have a certain elastic stress, and the inner cover 10 is configured as a plastic part so that the cover structure 100 can be used with the container.

[0045] like Figure 3 and Figure 4As shown, the inner wall of the accommodating cavity 11 is provided with an anti-rotation part 12, and the connector 20 is provided with an anti-rotation notch 22. The anti-rotation part 12 and the anti-rotation notch 22 can be circumferentially limited and engaged in the accommodating cavity 11. In this way, the connector 20 and the inner cover 10 can be prevented from separating when the cover structure 100 makes circumferential rotational movement, so as to further improve the stability of the connection between the connector 20 and the inner cover 10.

[0046] Preferably, a guide portion 121 is provided at the end of the anti-rotation portion 12 facing the outer cover 30. The guide portion 121 is used to guide the anti-rotation portion 12 into the anti-rotation notch 22. Here, the guide portion 121 has a guiding function, which can guide the anti-rotation notch 22 to align with the anti-rotation portion 12 when the connector 20 is assembled with the inner cover 10, so that the assembly is more accurate and reliable.

[0047] Here, the guide portion 121 can be configured as a triangular portion, a conical portion, etc.

[0048] Please continue to refer to this. Figures 2 to 4 The connector 20 is snapped into the inner wall of the accommodating cavity 11 by a snap-fit ​​structure 21, so as to realize the detachable connection between the connector 20 and the inner cover 10.

[0049] Preferably, multiple snap-fit ​​structures 21 are provided, and the multiple snap-fit ​​structures 21 are spaced apart along the circumference of the receiving cavity 11. In this way, providing multiple snap-fit ​​structures 21 can strengthen the connection between the connector 20 and the inner cover 10, making the assembly structure between the two more stable.

[0050] Furthermore, the snap-fit ​​structure 21 includes an elastic snap-fit ​​arm 211 and a snap-fit ​​groove 212. One of the elastic snap-fit ​​arm 211 and the snap-fit ​​groove 212 is provided with the inner wall of the receiving cavity 11, and the other is provided with the outer wall of the connector 20. When the connector 20 is inserted into the receiving cavity 11, the elastic snap-fit ​​arm 211 snaps into the snap-fit ​​groove 212. In this way, through the cooperation of the elastic snap-fit ​​arm 211 and the snap-fit ​​groove 212, the inner cover 10 can be limited and connected to the connector 20 in both the axial and circumferential directions of the cover structure 100, thereby improving the stability of the connection between the connector 20 and the inner cover 10.

[0051] Furthermore, the elastic locking arm 211 has a first contact surface 2111 and a second contact surface 2112, and the locking groove 212 includes a first groove wall 2121 and a second groove wall 2122. The first groove wall 2121 and the second groove wall 2122 are connected and set at an angle. The first contact surface 2111 is matched with the first groove wall 2121, and the second contact surface 2112 is matched with the second groove wall 2122. When the elastic locking arm 211 is engaged in the locking groove 212, the first contact surface 2111 and the first groove wall 2121 are engaged, and the second contact surface 2112 and the second groove wall 2122 are engaged. In this way, the contact area between the connector 20 and the inner cover 10 can be increased, thereby increasing the friction between the two and effectively improving the stability of the connection between the connector 20 and the inner cover 10.

[0052] Here, the angle between the first groove wall 2121 and the second groove wall 2122 can be θ, 100° < θ < 180°, that is, θ can take the value of 100°, 150°, 175°, etc. The specific value of θ can be determined according to the actual situation and is not limited here.

[0053] In one embodiment, both the connector 20 and the outer cover 30 are configured as metal parts. It is understood that metal parts can be connected by welding, and metal parts have high strength. Configuring the outer cover 30 and the connector 20 as metal parts can increase the impact stress of the outer cover 30, thereby improving its structural rigidity.

[0054] Furthermore, a weld point 23 is provided on the side of the connector 20 facing away from the accommodating cavity 11, and the weld point 23 is set as an energy storage weld point. It can be understood that by welding the connector 20 to the outer cover 30 through energy storage welding, the advantages of the energy storage welding, such as a very small heat-affected zone and high strength, can be utilized to reduce thermal damage to the connector 20 and the outer cover 30, as well as welding defects such as welding deformation and cracks, and improve the connection strength between the two.

[0055] like Figure 2 As shown, the cover structure 100 also includes heat-insulating foam 40, which is embedded in the receiving cavity 11 and extends into the connector 20. It can be understood that the heat-insulating foam 40 has a heat-insulating function. Placing the heat-insulating foam 40 between the inner cover 10 and the connector 20 enables the cover structure 100 to have a heat-insulating effect, thereby increasing the scope of use of the cover structure 100.

[0056] In one embodiment, the cover structure 100 further includes a decorative piece 50 disposed on a side of the outer cover 30 opposite to the receiving cavity 11.

[0057] This application also provides the following technical solutions:

[0058] A container comprising the lid structure 100 described in any of the above embodiments.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
