Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0025] In this application, unless otherwise expressly specified and limited, the terms "assembly," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] As shown in Figures 1 and 2, a plastic bottle manufactured using a blow-fill-seal equipment has a groove 2 on the top of the bottle body. The groove 2 is open at both ends. By providing the groove 2 on the top of the bottle body, the curved surfaces on both sides of the groove 2 can guide the bottle during puncture, facilitating use and puncture. The open-ended design of the groove 2 ensures that there is no undercut between the open end and the mold opening direction during plastic bottle molding, preventing the top of the bottle from being damaged by the mold and leaving an indentation, thus ensuring the aesthetic appearance of the plastic bottle. This mold can produce plastic bottles with an attractive appearance and a guiding function during puncture.
[0028] The top of the bottle body is symmetrically provided with guide parts 1, and the guide parts 1 have a groove 2 in the middle. The middle end of the guide parts 1 is higher than the two ends of the guide parts 1, and the center of the groove 2 is not lower than the two ends of the groove 2. The two ends of the guide parts 1 are connected to the two ends of the groove 2. The parting line 3 of the bottle body is connected to the middle end of the guide parts 1. When the bottle body is molded, the parting line 3 passes through the middle end of the guide parts 1 and the center of the groove 2. Since the middle end of the guide parts 1 is higher than the two ends of the guide parts 1, and the center of the groove 2 is not lower than the two ends of the groove 2, when the mold is opened, the parting line 3 moves from the middle end of the guide parts 1 to the two ends of the guide parts 1, and from the center of the groove 2 to the two ends of the groove 2. This ensures that the parting line 3 always moves from a high position to a low position. The bottle body structure ensures that the guide area can be formed during the molding of the bottle body, while avoiding damage to the bottle body when the mold is opened.
[0029] The bottle body is provided with a thread 4, and the bottle body is connected to the cap 5 through the thread 4. The cap 5 is provided with a pin 6, and an anti-theft buckle 12 is provided between the bottle body and the cap 5, forming a complete eye drop bottle. The anti-theft buckle 12 facilitates the sealed transportation of the bottle body, and the thread 4 connects the bottle body and the cap 5, making it easy for the user to open. The pin 6 on the cap 5 facilitates puncturing the bottle body for use. By closing the cap 5, the pin 6 can seal the opening on the punctured groove 2, making it convenient for reuse.
[0030] The groove 2 is lower than the middle of the guide part 1, ensuring that the guide part 1 can guide the piercing process when the groove 2 is pierced by the needle tip.
[0031] The groove 2 is higher than or level with both ends of the guide part 1. When the mold is opened, the top structure of the bottle body that is in contact with the mold on the opening path moves from high to low or moves level, thereby avoiding the mold from scratching the bottle head and ensuring the aesthetics of the bottle body.
[0032] As shown in Figure 3, a mold is used to form or seal the bottle head of a plastic bottle manufactured by a blow-fill-seal equipment as described above, ensuring that the formed bottle body has an aesthetically pleasing appearance and a puncture guide function. This mold can be a separate bottle head sealing mold. In other embodiments, such as using a bottom sealing method, it can also be a molding mold that forms the bottle head and bottle body together.
[0033] It includes a cavity 7 for molding the top of the bottle head, the cavity 7 including a protrusion for molding a groove 2, the groove 2 is formed by the protrusion and the groove 2 guides the puncture process.
[0034] It also includes a parting line 8, which has a first recessed section 9, a protruding section 10, and a second recessed section 11 along the cavity 7. The parting line 8 on the mold is used to form the parting line 3 on the bottle body.
[0035] The height of the mold cavity 7 extending along the opening direction of the molding mold is less than or equal to the height of the mold at the location of the parting line 8. When the mold is opened, the parting line 8 is always located at the thickest position of the molding mold (as shown in Figure 3, when viewed from above, the parting line 8 is located at the lowest position, the position closest to the bottle body), thereby avoiding the parting line 8 from scratching the bottle head.
[0036] While this application has disclosed preferred embodiments above, it is not intended to limit this application. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this application, or modify them into equivalent embodiments, without departing from the scope of the technical solutions of this application. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this application, without departing from the content of the technical solutions of this application, should fall within the protection scope of the technical solutions of this application.
