Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a lightweight, thin-walled, environmentally friendly plastic bottle. Background Technology

[0002] In the packaging industry, plastic bottles, as a common packaging container, are widely used in many industries such as food, beverages, and daily necessities. Traditional plastic bottles are mostly made of non-degradable common plastics, such as polyethylene and polypropylene. These plastics are difficult to degrade in the natural environment, and the large-scale disposal of discarded plastic bottles causes serious "white pollution," posing a long-term and severe threat to the ecological environment, which is inconsistent with the current concepts of green environmental protection and sustainable development. At the same time, the anti-theft features of existing plastic bottles are imperfect, making it difficult for consumers to determine whether the product has been opened before purchase, thus failing to effectively protect consumer rights. Furthermore, traditional plastic bottles often cannot achieve a lightweight design while maintaining strength, resulting in a larger material usage, increased costs, and higher energy consumption during transportation.

[0003] Based on the above, this utility model proposes a lightweight, thin-walled, environmentally friendly plastic bottle that can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a lightweight, thin-walled, environmentally friendly plastic bottle.

[0005] This utility model is achieved through the following technical solution:

[0006] A lightweight, thin-walled, environmentally friendly plastic bottle is characterized by comprising a bottle body and a bottle cap, both of which are made of environmentally friendly plastic; the top of the bottle body is provided with a bottle mouth, and the outer side wall of the bottle mouth is provided with an annular groove; the bottle cap includes an annular ring installed in the annular groove, one end of the annular ring being movably connected to a cap body for sealing the bottle mouth via a connecting piece, and a tearable tamper-evident strip is provided between the cap body and the annular ring, with a handle fixedly connected to the outer side of one end of the tamper-evident strip.

[0007] According to the above technical solution, as a further preferred technical solution, the environmentally friendly plastic is any one of polylactic acid, polyhydroxyalkanoate, or polybutylene terephthalate.

[0008] According to the above technical solution, as a further preferred technical solution, the wall thickness of the bottle body is 0.3mm-0.6mm.

[0009] According to the above technical solution, as a further preferred technical solution, the end of the cover away from the connecting piece is provided with an opening portion.

[0010] According to the above technical solution, as a further preferred technical solution, the annular ring is fixedly connected to the upwardly extending protective plates on both sides of the connecting piece.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] This utility model provides a lightweight, thin-walled, environmentally friendly plastic bottle. The bottle body and cap are made of environmentally friendly plastic, reducing the impact on the ecosystem and highlighting its environmental characteristics. Simultaneously, the annular grooves on the top of the bottle and the outer wall, in conjunction with the annular ring, connecting piece, and cap body of the cap, achieve an effective connection between the cap and the bottle body and a sealed opening. Furthermore, the inclusion of an anti-theft strip ensures a tight connection between the cap body and the annular ring when unopened; once torn, it cannot be resealed, clearly demonstrating to consumers whether the product has been opened, thus protecting product integrity and consumer rights. Additionally, the anti-theft strip is fixedly connected to a handle, facilitating the opening of the cap and enhancing the user experience. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] A lightweight, thin-walled, environmentally friendly plastic bottle includes a bottle body 1 and a bottle cap 2, both of which are made of environmentally friendly plastic. The bottle body 1 has a bottle mouth 11 at its top, and an annular groove 12 is provided on the outer side wall of the bottle mouth 11. The bottle cap 2 includes an annular ring 21 installed in the annular groove 12. One end of the annular ring 21 is movably connected to a cap body 23 for sealing the bottle mouth 11 via a connecting piece 22. A tearable tamper-evident strip 3 is provided between the cap body 23 and the annular ring 21, and a handle 31 is fixedly connected to the outer side of one end of the tamper-evident strip 3.

[0018] The bottle body 1 and bottle cap 2 of this utility model are made of environmentally friendly plastic, reducing the impact on the ecosystem and highlighting environmental protection characteristics. At the same time, the bottle mouth 11 at the top of the bottle body 1 and the annular groove 12 on the outer wall cooperate with the annular ring 21, connecting piece 22 and cap body 23 of the bottle cap 2 to achieve effective connection between the bottle cap 2 and the bottle body 1 and seal the bottle mouth 11. In addition, by setting an anti-theft strip 3, when unopened, the anti-theft strip 3 is tightly connected to the cap body 23 and the annular ring 21. Once torn, it cannot be restored, clearly showing consumers whether the product has been opened, maintaining the integrity of the product and protecting consumer rights. At the same time, the anti-theft strip 3 is fixedly connected to a handle 31, which makes it easy to tear open the anti-theft strip and open the bottle cap, making it convenient for consumers to open and improving the user experience.

[0019] Furthermore, in another embodiment, the environmentally friendly plastic is any one of polylactic acid, polyhydroxyalkanoate, or polybutylene terephthalate.

[0020] The bottle body 1 and bottle cap 2, made of the aforementioned materials, have good biodegradability, which can effectively reduce environmental pollution and is in line with the concept of sustainable development.

[0021] Furthermore, in another embodiment, the wall thickness of the bottle body 1 is 0.3mm-0.6mm.

[0022] By setting the wall thickness of bottle 1 to 0.3mm-0.6mm, the bottle body has a certain strength while achieving the design requirements of lightweight and thin walls, reducing the amount of material used, reducing the weight of the bottle body, which is conducive to saving costs and reducing energy consumption during transportation.

[0023] Furthermore, in another embodiment, the end of the cover 23 away from the connecting piece 22 is provided with an opening portion 24.

[0024] By setting the opening part 24, the user can easily open the bottle cap 2, which improves the user experience and makes the opening operation more convenient and effortless.

[0025] Furthermore, in another embodiment, the annular ring 21 is fixedly connected to the upwardly extending protective plates 25 on both sides of the connecting piece 22.

[0026] By setting the protective piece 25, the connecting piece 22 is protected to a certain extent, preventing it from being damaged by external forces such as collision and squeezing during transportation and storage, and ensuring that the bottle cap opening and closing function is normal.

[0027] Based on the description and accompanying drawings of this utility model, those skilled in the art can easily manufacture or use the lightweight, thin-walled, environmentally friendly plastic bottle of this utility model, and can achieve the positive effects described in this utility model.
