Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle production, in particular to a bottle preform with a lightweight bottle mouth. Background Art

[0002] In the production process, the preform is first processed and then placed in the mold for blow molding. The preform is formed by injection molding by filling the raw materials into the gun mold of the mold under specific temperature and pressure. It is formed under the working conditions of the injection molding machine. After injection molding, it becomes a semi-finished intermediate product, and then undergoes blow molding to become the end product.

[0003] In the prior art, some bottle preforms have thick necks due to functional requirements, and the concentrated material consumption is relatively high. This results in a large amount of raw materials used in processing, which increases manufacturing costs. Therefore, a bottle preform with a lightweight neck is proposed to solve the above problems. Utility Model Content

[0004] The utility model provides a bottle preform with a lightweight bottle mouth, aiming to improve the problem of a heavy bottle preform mouth in some devices in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A bottle preform with a lightweight bottle mouth comprises a bottle preform body, the top of the bottle preform body is fixedly connected to the bottle preform mouth, a plurality of grooves are formed inside the bottle preform mouth, and a plurality of spiral blocks are fixedly connected to the outside of the bottle preform mouth.

[0007] As a further description of the above technical solution:

[0008] The bottom of the bottle preform mouth is fixedly connected to a limiting ring, and the bottom of the limiting ring is fixedly connected to a reinforcement ring.

[0009] As a further description of the above technical solution:

[0010] A lightweight layer is fixedly connected to the outside of the preform body, and a heat-proof layer is fixedly connected to the outside of the lightweight layer.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, a plurality of grooves are opened inside the bottle preform mouth without affecting the structural performance of the bottle preform, thereby reducing the weight of the entire bottle preform. A plurality of spiral blocks are arranged in a spiral manner at the bottle preform mouth, thereby reducing the amount of raw materials used and reducing the weight of the bottle mouth. A reinforcement ring is installed on the top of the limiting ring, making the bottle mouth more solid and not easy to deform. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1 、 Figure 3 The present invention provides an embodiment of a bottle preform with a lightweight bottle mouth, comprising a bottle preform body 1, which is the core part of the entire bottle preform. The shape of the bottle preform body 1 is usually cylindrical to facilitate subsequent thermoforming and blow molding processes. The top of the bottle preform body 1 is fixedly connected to a bottle preform mouth 2, which is responsible for closing and opening the bottle. A plurality of grooves 3 are provided inside the bottle preform mouth 2. The function of the grooves 3 is to reduce the weight of the bottle preform mouth 2 while not affecting normal functional use. A plurality of spiral blocks 4 are fixedly connected to the outside of the bottle preform mouth 2. The design of the spiral blocks 4 is usually spiral, which reduces the amount of raw materials used while reducing the weight of the bottle mouth without affecting the functional use.

[0021] Reference Figure 2 、 Figure 4The bottom of the preform mouth 2 is fixedly connected to a limit ring 5, which is fixed to the bottom of the preform mouth 2 and is mainly used to limit the rotation range of the bottle cap to ensure that the bottle cap does not rotate excessively when tightened. The bottom of the limit ring 5 is fixedly connected to a reinforcement ring 6 to enhance the structural strength of the preform mouth 2. The outside of the preform body 1 is fixedly connected to a lightweight layer 7. The material of the lightweight layer 7 is polyethylene (PE). PE has good toughness and impact resistance, is lightweight and relatively low in cost, and is widely used in various bottle mouth designs. The outside of the lightweight layer 7 is fixedly connected to a heat-proof layer 8. The material of the heat-proof layer 8 is polypropylene (PP). PP has good heat resistance and can withstand high temperatures.

[0022] Working Principle: During the production process, the preform body 1 is first formed through injection or blow molding to create a cylindrical base structure. Next, the preform mouth 2 is affixed to the top of the preform body 1. Multiple grooves 3 are formed within the mouth 2 during molding, reducing its weight without compromising its functionality. Subsequently, multiple screw blocks 4 are fixed to the outside of the preform mouth 2. These screw blocks 4 are designed to reduce raw material usage without compromising performance, further reducing the weight of the bottle mouth. A limit ring 5 is fixed to the bottom of the preform mouth 2 to prevent excessive rotation of the bottle cap during tightening, thereby avoiding damage to the bottle mouth structure. A reinforcement ring 6 is attached to the bottom of the limit ring 5, enhancing the overall structural strength of the preform mouth 2 and ensuring its stability and reliability during use. A lightweight layer 7 is fixed to the outside of the preform body 1. Made of polyethylene (PE), this material offers excellent toughness and impact resistance, while being cost-effective and suitable for large-scale production. The outside of the lightweight layer 7 is connected to the heat-proof layer 8, which is made of polypropylene (PP) material and has excellent heat resistance and can withstand higher temperatures.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
