The mold can form a plastic bottle with a beautiful appearance and a function of guiding when puncturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 A plastic bottle manufactured by a blow-fill-seal device according to the present invention;

[0020] Figure 2 A plastic bottle with a cover body manufactured by a blow-fill-seal device according to the present invention;

[0021] Figure 3 A mold of the present invention.

[0022] The reference numerals of the present invention in the figure are as follows: 1. guide portion; 2. groove; 3. parting line; 4. thread; 5. cover body; 6. ejector pin; 7. cavity; 8. parting line; 9. first concave section; 10. protruding section; 11. second concave section.

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 to Figure 2 As shown, a plastic bottle manufactured by a blow-fill-seal device has a groove 2 on the top of the bottle body, and the two ends of the groove 2 are set through. By setting the groove on the top of the bottle body, the curved surfaces on both sides of the groove can guide when puncturing, which is convenient for use and puncturing. The two ends of the groove are set through. When the plastic bottle is formed, there is no undercut between the through position and the mold opening direction. When the mold is opened, the top of the bottle body is prevented from being pulled by the mold to form a concave mark, ensuring the beautiful appearance of the plastic bottle. The mold can form a plastic bottle with a beautiful appearance and the function of guiding when puncturing.

[0025] A guide portion 1 is symmetrically provided on the top of the bottle body, and a groove 2 is provided in the middle of the guide portion 1. The middle end of the guide portion 1 is higher than the two ends of the guide portion 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 portion 1 are connected to the two ends of the groove 2, and the parting line 3 of the bottle body is connected to the middle end of the guide portion 1. When the bottle body is molded, the parting line 3 passes through the middle end of the guide portion 1 and the center of the groove 2. Since the middle end of the guide portion 1 is higher than the two ends of the guide portion 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 portion 1 to the two ends of the guide portion 1, and from the center of the groove 2 to the two ends of the groove 2, thereby ensuring that the parting line 3 always moves from a high position to a low position. The bottle body structure ensures that when the bottle body is molded, the guide area can be molded while avoiding damage to the bottle body during mold opening.

[0026] The bottle body is provided with a thread 4, and the bottle body is connected to the cover body 5 through the thread 4. The cover body 5 is provided with a thimble 6. An anti-theft buckle 12 is provided between the bottle body and the cover body 5 of the bottle body, forming a complete eye drop bottle. The anti-theft buckle 12 facilitates the sealed transportation of the bottle body, and the bottle body and the cover body 5 are connected by threads to facilitate users to open. By arranging the thimble 6 on the cover body 5, it is convenient to puncture and use the bottle body. By closing the cover body 5, the thimble 6 can seal the opening on the punctured groove 2, which is convenient for repeated use.

[0027] The groove 2 is lower than the middle end of the guide part 1, so as to ensure that when the groove 2 is punctured by the needle tip, the guide part 1 can guide the puncturing process.

[0028] The groove 2 is higher than or level with the two ends of the guide part 1. When the mold is opened, the bottle top structure touched by the mold on the opening path moves from high to low, or moves levelly, thereby preventing the mold from scratching the bottle head and ensuring the beauty of the bottle.

[0029] like Figure 3 As shown, a mold is used to form or seal the bottle head of a plastic bottle manufactured by a blow-fill-seal device as described above, ensuring that a bottle body with a beautiful appearance and a puncture guide function is formed. The mold can be a separate bottle head sealing mold. In other embodiments, such as using a bottle bottom sealing method, the bottle head and the bottle body can also be formed together.

[0030] It comprises a cavity 7 for forming the top of the bottle head, and the cavity 7 comprises a protrusion for forming the groove 2. The groove 2 is formed by the protrusion, and the puncture process is guided by the groove 2.

[0031] The mold further comprises a parting line 8, wherein the parting line 8 is respectively provided with a first concave section 9, a convex section 10 and a second concave section 11 along the mold cavity 7. The parting line 8 on the mold is used to form the parting line 3 on the bottle body.

[0032] The mold height of the mold cavity 7 extending along the direction of the mold opening is less than or equal to the mold height 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 mold (such as Figure 3 As shown, looking from top to bottom, the parting line 8 is located at the lowest position, the position closest to the bottle body), thereby preventing the parting line 8 from scratching the bottle head.

[0033] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
