Description

Technical Field

[0001] This utility model relates to the field of plastic beverage bottle preform technology, and in particular to a plastic beverage bottle preform with radial reinforcing ribs. Background Technology

[0002] Plastic beverage preforms are an indispensable component of modern beverage packaging, widely used for packaging various beverages such as mineral water, carbonated drinks, and fruit juices. Traditional plastic beverage preforms are typically made of materials such as polyethylene terephthalate (PET), which have advantages such as being lightweight, transparent, and impact-resistant. However, with consumers' increasing demands for beverage packaging quality and their growing focus on environmental protection and sustainable development, the design and performance of traditional plastic beverage preforms are no longer sufficient to meet the needs of modern industrial production.

[0003] Traditional plastic beverage bottle preforms are prone to deformation under external pressure, especially at the bottle neck and bottom, which affects the sealing and stability of the packaging. During transportation and storage, the preforms are easily squeezed, leading to bottle deformation or breakage, affecting product quality and appearance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a plastic beverage bottle preform with radial reinforcing ribs.

[0005] This utility model is achieved by the following technical solution: a plastic beverage bottle preform with radial reinforcing ribs, comprising a preform body, a bottle mouth fixedly connected to the top of the preform body, an external thread on the surface of the bottle mouth, the external thread surface being threadedly connected to the inner wall of the bottle cap, a reinforcing connecting plate fixedly connected to the surface of the preform body, two reinforcing connecting plates being provided, the two reinforcing connecting plates being symmetrically distributed at the center of the preform body, a radial reinforcing rib body being fixedly connected to the inner wall of the reinforcing connecting plate, a plurality of radial reinforcing rib bodies being provided, the plurality of radial reinforcing rib bodies extending radially inside the two reinforcing connecting plates respectively.

[0006] Through the above technical solution, the bottle mouth surface is provided with external threads for threaded connection with the bottle cap, ensuring that the bottle cap can be tightly fixed to the bottle mouth to prevent liquid leakage. The tight fit with the bottle cap provides excellent sealing performance, preventing liquid leakage during transportation and storage. Two reinforcing connecting plates are provided, symmetrically distributed at the center of the preform body, further enhancing the overall structural strength of the preform. They provide additional support when the bottle body is under pressure, ensuring the stability of the bottle body. These plates also serve as fixing connection points for the radial reinforcing ribs, ensuring the stability and effectiveness of the reinforcing ribs. The radial reinforcing ribs extend along the radial direction of the preform body and are evenly distributed on the preform surface, effectively dispersing pressure, preventing bottle deformation or breakage, and improving the bottle's pressure resistance. Through the synergistic effect of multiple reinforcing ribs, the overall structural strength of the preform is significantly improved, ensuring the stability of the bottle body during transportation and use.

[0007] As a further improvement to the above scheme, the preform body is made of polyethylene terephthalate, and the thickness of several radial reinforcing ribs is 0.5-1.5 mm.

[0008] Through the above technical solution, the preform body is made of polyethylene terephthalate (PET) material, which has the advantages of being lightweight, transparent and impact-resistant. At the same time, the amount of material used is reduced by optimizing the design, thus reducing the production cost. By optimizing the layout and thickness of the reinforcing ribs (0.5-1.5mm), the amount of material used is reduced while ensuring strength, thus achieving a lightweight design.

[0009] As a further improvement to the above solution, an anti-slip pad is fixedly connected to the bottom end of the preform body, and the bottom end of the anti-slip pad is in contact with the outside.

[0010] Through the above technical solution, the anti-slip pad is fixedly connected to the bottom of the preform body, which increases the friction between the bottom of the bottle and the contact surface, prevents the bottle from sliding or rolling, improves the stability during use, reduces the direct friction between the bottom of the bottle and the contact surface, prevents wear on the bottom of the bottle, and extends the service life of the bottle.

[0011] As a further improvement to the above solution, a protective shell is fixedly connected to the surface of the preform body, and the surface of the protective shell is in contact with the surface of a plurality of radial reinforcing rib bodies.

[0012] Through the above technical solution, the protective shell is fixedly connected to the outer wall of the preform body, which can effectively protect the preform body from external impact and extend the service life of the bottle. The design of the protective shell can realize personalized appearance design to meet the appearance requirements of different brands and products. The contact between the protective shell and the radial reinforcing rib body further enhances the overall structural strength of the bottle.

[0013] As a further improvement to the above solution, the surface of the protective shell is provided with slots, two slots are provided, and the inner walls of the two slots are provided with anti-slip protrusions. There are a number of anti-slip protrusions, and the bottle preform body is fixedly connected to one end of the number of anti-slip protrusions that are close to each other. The number of anti-slip protrusions are symmetrically distributed at the center of the bottle preform body.

[0014] Through the above technical solution, the anti-slip protrusions are set on the inner wall of the groove on the surface of the protective shell, which increases the friction between the bottle and the hand, prevents the bottle from slipping when gripping, and improves the safety of use. They can be designed into different shapes and patterns as needed to increase the aesthetics and recognizability of the product. The fixed connection between the anti-slip protrusions and the bottle preform body further enhances the structural strength of the bottle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention significantly improves the compressive strength and deformation resistance of the preform by setting multiple radial reinforcing ribs on the surface of the preform body, especially in the bottle mouth and bottom areas, effectively preventing deformation and breakage of the bottle body during transportation and use; two reinforcing connecting plates are symmetrically distributed at the center of the preform body, further enhancing the overall structural strength of the preform and ensuring that the bottle body can remain stable under pressure. This invention features an anti-slip pad fixedly connected to the bottom of the bottle preform, increasing the friction between the bottle bottom and the contact surface, preventing the bottle from sliding or rolling, and improving stability during use. Several anti-slip protrusions are provided on the inner wall of the groove on the surface of the protective outer shell, further increasing the friction between the bottle and the hand, preventing the bottle from slipping when grasped, and improving safety during use. The preform body is made of polyethylene terephthalate (PET), which has the advantages of being lightweight, transparent, and impact-resistant. At the same time, through optimized design, the amount of material used has been reduced, achieving a lightweight design and reducing production costs. Attached Figure Description

[0021] A protective shell 6 is fixedly connected to the surface of the preform body 1, and the surface of the protective shell 6 is in contact with the surface of several radial reinforcing rib bodies 9.

[0022] The protective shell 6 has two slots on its surface, and the inner walls of the two slots are provided with anti-slip protrusions 7. There are several anti-slip protrusions 7.

[0023] Several anti-slip protrusions 7 are fixedly connected to the preform body 1 at one end, and the several anti-slip protrusions 7 are symmetrically distributed at the center of the preform body 1.

[0024] The implementation principle of a plastic beverage bottle preform with radial reinforcing ribs in this embodiment is as follows: the radial reinforcing ribs 9 extend radially along the preform body 1 and are evenly distributed on the surface of the preform.

Two reinforcing connecting plates 8 are symmetrically distributed at the center of the preform body 1, further enhancing the overall structural strength of the preform. When the bottle is under pressure, the reinforcing connecting plates 8 can provide additional support to ensure the stability of the bottle. An anti-slip pad 5 is fixedly connected to the bottom of the preform body 1, which increases the friction between the bottom of the bottle and the contact surface, prevents the bottle from sliding or rolling when placed, and improves the stability of the bottle. The surface of the protective shell 6 is in contact with the surface of several radial reinforcing ribs 9, which can effectively protect the preform body 1 from external impacts. The protective shell 6 not only increases the protective performance of the bottle, but also further enhances the anti-slip function through the grooves and anti-slip protrusions 7 on its surface. The inner wall of the groove on the surface of the protective shell 6 is provided with several anti-slip protrusions 7. These anti-slip protrusions 7 can increase the friction between the bottle and the hand, preventing the bottle from slipping when gripped. At the same time, the anti-slip protrusions 7 can be designed into different shapes and patterns as needed to increase the product's aesthetics and recognizability.
