Description

Technical Field

[0001] This utility model relates to the field of plastic caps, and in particular to a plastic cap structure for an environmentally friendly plastic bottle. Background Technology

[0002] Plastic bottle caps are an important component of plastic bottles, usually made of plastic materials such as polyethylene (PE) or polypropylene (PP). Their main function is to seal the bottle opening to prevent liquid leakage and external contaminants from entering the bottle. Among them, screw caps are the most common type, which users open or close the bottle by rotating them.

[0003] Furthermore, to improve the stability of cap installation, a limiting ring is set at the bottom of the cap. The limiting ring is engaged with the plastic flat end and is connected to the cap through multiple contacts. When the cap is removed, the contacts break, causing the cap to separate from the limiting ring. However, with this design, the limiting ring cannot restrain the cap again when it is reinstalled, thus reducing its practical performance and having certain defects. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figure 1-3 The image shows the structure of a plastic cap for an environmentally friendly plastic bottle.

[0034] Example 1: Includes a screw cap body 1, a sealing plug 2, an arc plate 3, a connector 5, and a limiting assembly 6. The sealing plug 2 is fitted inside the screw cap body 1 and is used to seal the connection between the screw cap body 1 and the plastic bottle, thereby improving the sealing performance between the screw cap body 1 and the plastic bottle. The arc plate 3 is symmetrically arranged on the screw cap body 1, and an arc block 4 that engages with the plastic bottle is fixedly connected to the inner wall of the arc plate 3. The connector 5 connects the arc plate 3 and the screw cap body 1. The connector 5, the screw cap body 1, the arc plate 3, and the arc block 4 are all made of plastic, and their production... The production process uses injection molding, which is existing technology and will not be described in detail here. The connector 5 can be bent to a certain extent, so that the arc plate 3 can rotate relative to the capping body 1 through the connector 5. Thus, when the capping body 1 is installed or removed, the arc plate 3 can be connected or separated from the plastic bottle mouth by rotating through the connector 5. The limiting component 6 is set on the side of the arc plate 3. The limiting component 6 is used to give the arc plate 3 on the capping body 1 a relatively cohesive limiting elastic force. The limiting component 6 can improve the stability of the two arc plates 3 being engaged with the plastic bottle mouth by the arc block 4.

[0035] Furthermore, the limiting component 6 includes a connecting block 61 and an elastic band 63. The connecting block 61 is fixedly connected to the side of the arc plate 3. An installation groove 62 is provided on one side of the connecting block 61. The elastic band 63 is disposed inside the installation groove 62. The elastic band 63 acts on the adjacent connecting blocks 61 with a cohesive elastic force. Under the action of the elastic band 63, the two arc plates 3 can have a relatively cohesive elastic force, thereby improving the stability of the arc plate 3 when it is snapped into the plastic bottle mouth.

[0036] Furthermore, the limiting component 6 also includes a first limiting plate 64 and a second limiting plate 65. A limiting groove is formed at one end of the inner wall of the mounting groove 62. The first limiting plate 64 is slidably engaged in one of the limiting grooves. One end of the elastic band 63 is fixedly connected to the first limiting plate 64. The second limiting plate 65 is slidably engaged in the other limiting groove. The other end of the elastic band 63 is installed on one side of the second limiting plate 65. The first limiting plate 64 and the second limiting plate 65 are respectively engaged on opposite sides of the two connecting blocks 61. Thus, the elastic band 63 can provide an elastic cohesive force to the two connecting blocks 61 through the first limiting plate 64 and the second limiting plate 65.

[0037] Example 2: Based on Example 1, the limiting component 6 further includes a connecting plate 66 and a snap-fit ​​component 67. The connecting plate 66 is disposed inside the mounting groove 62, and the other end of the elastic band 63 is fixedly connected to the connecting plate 66. The snap-fit ​​component 67 is fixedly connected to one side of the second limiting plate 65. The snap-fit ​​component 67 fits against the inner wall of the mounting groove 62 and slides to snap onto the end of the outer wall of the connecting plate 66. The snap-fit ​​component 67 is L-shaped, and under the constraint of the inner cavity space of the mounting groove 62, the stability of the snap-fit ​​between the connecting plate 66 and the two snap-fit ​​components 67 can be guaranteed.

[0038] Furthermore, the limiting component 6 also includes a first positioning block 68 and a through hole. The first positioning block 68 is fixedly connected to one side of the snap-fit ​​member 67. A first positioning groove is provided at the end of the side of the connecting plate 66. The outer wall of the first positioning block 68 is slidably snapped into the inner cavity of the first positioning groove. The first positioning block 68 can improve the stability of the snap-fit ​​between the connecting plate 66 and the two snap-fit ​​members 67. The through hole is opened on one side of the connecting plate 66. By using the hook rod to snap into the through hole, the connecting plate 66 can be pulled out from the mounting groove 62, so that the connecting plate 66 can snap into the two snap-fit ​​members 67 on one side of the second limiting plate 65, so as to facilitate its assembly.

[0039] Furthermore, the limiting component 6 also includes a second positioning block 69 and a second positioning groove. The second positioning block 69 is fixedly connected to one side of the first limiting plate 64, and the second positioning groove is opened on the side of the inner wall of the mounting groove 62. The outer wall of the second positioning block 69 is slidably engaged with the inner cavity of the second positioning groove. The second positioning block 69 can improve the stability of the installation of the first limiting plate 64.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
