Description

Technical Field

[0001] This utility model relates to the field of packaging-related technology, and in particular to a top cap with an external snap-on design. Background Technology

[0002] Current plastic bottle caps are mainly molded in one piece and are a single color, resulting in a rather monotonous appearance. It's not easy to distinguish different items by the color of the cap, and when there are many bottles, it's necessary to open each cap individually for identification, causing significant inconvenience. While two-color bottle caps offer vibrant colors, the expensive injection molding equipment and high production costs limit their widespread use. Therefore, most bottle caps use a separate cap glued or heat-bonded top for differentiation. However, this method requires removing each cap individually to observe the top, which is difficult to do for bottles located high up.

[0003] Chinese Patent Publication No. CN201372016Y, published on December 30, 2009, discloses a two-color plastic bottle cap, comprising a cap body. Its key feature is the inclusion of an insert plate of a different color from the cap body. A recess for mounting the insert plate is located at the top of the cap body, and the peripheral curve of the recess corresponds to the peripheral curve of the insert plate. The insert plate and the recess have a shape that is smaller at the top and larger at the bottom along their periphery. A drawback of this invention is that, while differentiating the cap by using different insert plates at the top, it is not easily observable from the side. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies where it is not easy to directly distinguish different storage bottles from the side. It provides a top cap with different colored caps to distinguish storage bottles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A top-cap external snap-on bottle cap includes a bottle body, a bottle cap, and a top cap. The bottle cap is threaded to the upper end of the bottle body, a snap-fit ​​ring is installed on the bottle cap, the top cap is detachably connected to the snap-fit ​​ring, and a safety ring is installed at the lower end of the top cap.

[0007] The bottle body serves as the main structure, providing storage. After items are stored, the bottle cap is threaded onto the bottle body, sealing the opening. A top cap is then attached to the cap's snap ring, with its color distinguishing different items. This top cap is removable, allowing for replacement with different colored caps. The colors are visible from the side of the top cap, facilitating easy identification and retrieval. A safety ring at the bottom of the cap locks its rotation, preventing accidental opening during transport and potential spillage of stored items. This design achieves the goal of differentiating storage bottles by attaching different colored top caps.

[0008] Preferably, the bottle body has a bottleneck that communicates with the bottle body and is threadedly connected to the inner wall of the bottle cap. The bottleneck on the bottle body is used to connect to the bottle cap, facilitating the pouring of the contents. The bottle body is sealed by the threaded connection between the inner wall of the bottle cap and the bottleneck. Simultaneously, the bottle cap can be positioned on the outside of the bottle body for easy installation of the top cap. This design facilitates the installation of the bottle cap.

[0009] Preferably, the upper end of the bottle cap is provided with an extension ring, the inner wall of which is connected to the side of the bottle cap, and the outer wall of which is connected to one end of a clamping ring. The clamping ring has an annular groove, and a connecting ring is installed on the inner wall of the top cover. The top cover is detachably connected to the clamping ring through the cooperation of the connecting ring and the annular groove. An extension ring is installed at the upper end of the bottle cap, and a clamping ring is installed on the extension ring, ensuring that the diameter of the clamping ring is larger than the diameter of the bottle cap. The larger upper end facilitates the screwing and turning of the bottle cap. By cooperating between the connecting ring on the inner wall of the top cover and the annular groove on the side of the clamping ring, pressing the top cover forces the connecting ring into the annular groove, thus connecting the bottle cap and the top cover. This creates a different color for the top cover, making it easier to distinguish. Simultaneously, the larger top cover facilitates the application of circumferential force to rotate the bottle cap. This connection method facilitates the removal and replacement of the top cover, and this design allows for the installation of the top cover.

[0010] Preferably, the top cover has several circumferentially distributed locking blocks on its side. A limiting groove is installed on the top surface of the clamping ring, and several circumferentially distributed inserts are installed within the limiting groove, with each insert positioned between two adjacent locking blocks. To ensure that rotating the top cover causes the bottle cap to rotate as well without relative displacement, a limiting mechanism between the top cover and the bottle cap is necessary. When installing the top cover, the inserts in the limiting groove of the clamping ring are inserted between two adjacent locking blocks on the inner wall of the top cover. The number of inserts is much smaller than the number of locking blocks, allowing for quick insertion between two adjacent locking blocks. The engagement of the connecting ring and the annular groove limits the vertical movement of the top cover, while the engagement of the inserts and locking blocks limits the rotation of the top cover, thus limiting the top cover and bottle cap together. Rotating the top cover causes the bottle cap to rotate as well, ensuring that the top cover and bottle cap rotate together.

[0011] Preferably, a limiting ring is installed on the bottle neck, and a safety ring is placed below the limiting ring. The safety ring has several circumferentially distributed fracture strips, one end of which is connected to the safety ring, and the other end of which is connected to the lower end face of the bottle cap. The limiting ring on the bottle neck is used to block the safety ring placed below the limiting ring. The safety ring is connected to the lower end face of the bottle cap through several fracture strips. The presence of the fracture strips ensures that the bottle cap will not be accidentally unscrewed. The safety ring placed below the limiting ring restricts the bottle cap from rising. Only when the applied external force reaches a certain level can the fracture strips be broken, thus requiring the bottle cap to be unscrewed. This design prevents the bottle cap from being accidentally unscrewed.

[0012] Preferably, the limiting ring has a triangular cross-sectional shape, and several circumferentially distributed stops are installed on the inner wall of the safety ring, with the stops positioned below the limiting ring. The triangular cross-sectional shape of the limiting ring allows for better pressing of the safety ring below it, and the stops on the inner wall of the safety ring, positioned below the limiting ring, effectively restrict the position of the safety ring.

[0013] The beneficial effects of this utility model are: different colored top caps are pressed onto the top of the bottle cap to distinguish the storage bottles, making it easy to install the bottle cap, ensuring that the top cap rotates together with the bottle cap, preventing the bottle cap from being accidentally unscrewed, and limiting the position of the safety ring.
