Description

Technical Field

[0001] This utility model relates to the field of beverage bottle technology, and in particular to a plastic beverage bottle preform with an arc-shaped transition structure at the bottom. Background Technology

[0002] In the beverage packaging industry, plastic beverage preforms are widely used as a key packaging form due to their many significant advantages. Their lightweight nature makes transportation and handling more convenient, greatly reducing logistics costs and minimizing environmental impact. The transparent appearance not only attracts consumers' attention but also allows them to see the color and state of the beverage directly, enhancing the product's appeal. In addition, the relatively low production cost of plastic beverage preforms enables beverage manufacturers to effectively control costs while ensuring product quality, thereby improving the product's market competitiveness.

[0003] However, traditional plastic beverage preforms have some limitations in design and function. For example, the bottom of traditional preforms usually adopts a right-angle or sharp transition structure. This structure is prone to stress concentration points during the molding process, resulting in insufficient strength and impact resistance of the preforms. During transportation and storage, the preforms are easily deformed or damaged by external forces, affecting the quality and appearance of the product. In addition, when traditional preforms are not in use, they mostly lack reasonable stacking design and can only be placed randomly, resulting in extremely low space utilization. This not only increases the demand for storage space but also increases transportation costs and reduces logistics efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a plastic beverage bottle preform with an arc-shaped transition structure at the bottom.

[0005] This utility model is achieved by the following technical solution: a plastic beverage bottle preform with an arc-shaped transition structure at the bottom, including a bottle body, an arc-shaped transition bottom fixedly connected to the lower surface of the bottle body, a stacking cavity opened inside the arc-shaped transition bottom, an upper circling rib fixedly connected to the outer surface of the bottle body, and a lower circling rib fixedly connected to the outer surface of the bottle body.

The surrounding ribs enhance the stability of the bottle body, prevent the bottle body from deforming during blow molding and transportation, and ensure the appearance and quality of the product.

[0007] As a further improvement to the above solution, the bottle body is a PET bottle body, and the arc transition bottom is a PET arc bottom.

[0008] Through the above technical solutions, PET material has high strength, high transparency and good chemical resistance, which can effectively protect the quality and taste of beverages, while improving the appearance of products.

[0010] The above technical solution, through the adaptation design of the stacking cavity and the top of the bottle body, further improves stacking efficiency and saves more storage and transportation space.

[0011] As a further improvement to the above solution, the number of friction protrusions is set to several, and the several friction protrusions are evenly distributed in a circumferential array on the outer surface of the bottle body.

[0012] As a further improvement to the above solution, the upper circling rib is fixedly connected to one side of the bottle body surface, and the lower circling rib is fixedly connected to the other side of the bottle body surface.

[0013] As a further improvement to the above solution, the lower surface of the arc transition bottom is fixedly connected with a support protrusion, and the number of the support protrusions is set to four, which are respectively fixedly connected to the four corners of the lower surface of the arc transition bottom.

[0014] Through the above technical solution, the design of the support bump provides stable support for the preform, preventing the preform from tilting or rolling during placement and improving the stability of the preform.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes an arc-shaped transition bottom to ensure more even stress distribution on the preform during molding, reducing stress concentration points and significantly improving the overall strength and impact resistance of the preform. The stacking cavity design allows preforms to be stacked on top of each other during production, greatly saving space and reducing transportation and storage costs. The upper and lower surrounding ribs effectively disperse the stress on the bottle body during blow molding and transportation, preventing bottle deformation and further enhancing structural stability. The friction protrusions not only increase friction when gripped, preventing the preform from sliding and falling, but also improve stacking stability. The support protrusions provide stable support, preventing the preform from tilting or rolling, ensuring the stability of the preform during blow molding and transportation.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0019] Please combine Figure 1-4 This embodiment describes a plastic beverage bottle preform with an arc-shaped transition structure at the bottom. It includes a bottle body 1, a rounded transition bottom 2 fixedly connected to the lower surface of the bottle body 1, a stacking cavity 3 inside the rounded transition bottom 2, an upper surrounding rib 4 fixedly connected to the outer surface of the bottle body 1, a lower surrounding rib 5 fixedly connected to the outer surface of the bottle body 1, and the rounded transition bottom 2 fixedly connected to the lower surface of the bottle body 1. This arc-shaped transition structure allows the preform to be subjected to more even stress during molding, reducing stress concentration points and thus improving the overall strength and impact resistance of the preform. The design of the stacking cavity 3 allows the preforms to be stacked on top of each other during production, saving space and facilitating transportation and storage. The upper surrounding rib 4 and the lower surrounding rib 5 further enhance the structural stability of the bottle body 1, preventing deformation of the bottle body during blow molding and transportation.

[0020] The bottle body 1 is a PET bottle body, and the rounded bottom 2 is a PET rounded bottom. PET is a material with excellent mechanical properties, transparency and chemical resistance, and is widely used in beverage packaging.

[0021] The stacking cavity 3 is adapted to the top of the bottle body 1. Friction protrusions 6 are fixedly connected to the outer surface of the bottle body 1, allowing multiple preforms to be stacked tightly together, further optimizing space utilization. In addition, friction protrusions 6 are fixedly connected to the outer surface of the bottle body 1. These protrusions increase friction when held by a person, preventing the preforms from sliding and falling.

[0022] The number of friction protrusions 6 is set to a certain number, and the several friction protrusions 6 are evenly distributed in a circumferential array on the outer surface of the bottle body 1.

[0023] The upper circling rib 4 is fixedly connected to one side of the surface of the bottle body 1, and the lower circling rib 5 is fixedly connected to the other side of the surface of the bottle body 1. This design allows the circling ribs to better distribute the stress on the bottle body 1 during blow molding and transportation, further enhancing the structural stability of the bottle.

[0024] The lower surface of the arc transition bottom 2 is fixedly connected with a support protrusion 7. There are four support protrusions 7, which are fixedly connected to the four corners of the lower surface of the arc transition bottom 2. The support protrusions 7 provide stable support when the preform is placed on a flat surface, preventing the preform from tilting or rolling, and ensuring the stability of the preform during blow molding and transportation.

[0025] The implementation principle of a plastic beverage bottle preform with an arc-shaped transition structure at the bottom in this embodiment is as follows: The bottle body 1 is made of PET material, which has excellent mechanical properties, transparency, and chemical resistance, making it suitable for beverage packaging. An arc-shaped transition bottom 2 is fixedly connected to the lower surface of the bottle body 1. This arc-shaped transition structure makes the preform more evenly stressed during the molding process, reducing stress concentration points and thus significantly improving the overall strength and impact resistance of the preform. In addition, a stacking cavity 3 is provided inside the arc-shaped transition bottom 2. This stacking cavity 3 is adapted to the top of the bottle body 1, allowing the preforms to be stacked on top of each other during production, greatly saving space and facilitating transportation and storage. An upper circling rib 4 and a lower circling rib are fixedly connected to the outer surface of the bottle body 1. 5. The upper circumferential rib 4 is fixedly connected to one side of the surface of the bottle body 1, and the lower circumferential rib 5 is fixedly connected to the other side of the surface of the bottle body 1. This allows the circumferential rib to better distribute the stress on the bottle body 1 during blow molding and transportation, prevent bottle deformation, and further enhance the structural stability of the bottle body. Several friction protrusions 6 are also fixedly connected to the outer surface of the bottle body 1. These friction protrusions 6 are evenly distributed in a circumferential array. When a person holds the preform, the friction protrusions 6 increase the friction between the hand and the preform, effectively preventing the preform from sliding and falling, and improving the safety of use. The support protrusions 7 provide stable support when the preform is placed on a flat surface, preventing the preform from tilting or rolling, and ensuring the stability of the preform during blow molding and transportation.

[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
