Description

Technical Field

[0001] This utility model relates to the technical field of bottle protection devices, and in particular to a PE bottle anti-drop buffer protective cover. Background Technology

[0002] PE bottles, as a common packaging container, are widely used in chemical, pharmaceutical, and daily necessities industries due to their lightweight and low cost. However, during storage, transportation, and use, especially when containing valuable or hazardous materials, PE bottles are prone to breakage, deformation, or leakage due to impact if accidentally dropped, resulting in economic losses or even safety hazards.

[0003] To protect PE bottles, existing technologies typically use protective sleeves to wrap the bottle body. However, most current protective sleeves have a simple structure, such as being made of only a single layer of silicone or fabric. Their limited material composition and cushioning performance result in ineffective protection when a PE bottle falls from a height. This simple structure cannot effectively absorb and disperse the enormous impact energy; the impact force still concentrates on the bottle body, leading to poor protection and difficulty in effectively preventing damage.

[0004] More importantly, the way these protective sleeves are secured to PE bottles is usually quite rudimentary, relying mostly on the elasticity of the material itself or simple pull cords for tightening. This connection method is not secure enough, and the protective sleeve is prone to loosening, shifting, or even separating from the bottle during daily handling, movement, or shaking. Once the protective sleeve detaches, it completely loses its protective function, rendering the so-called drop protection ineffective and unable to provide stable and reliable protection.

[0005] Therefore, this utility model proposes a PE bottle anti-drop buffer protective cover to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a PE bottle anti-drop cushioning protective cover, which aims to improve the problems of the existing PE bottle anti-drop cushioning protective cover, such as simple cushioning structure, insufficient protective performance, and loose connection with PE bottle, which makes it easy to fall off during use. This utility model aims to provide a PE bottle anti-drop cushioning protective cover with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PE bottle anti-drop buffer protective cover, including an anti-drop mechanism and an anti-detachment component.

[0008] The anti-detachment component is passed through and fixedly connected to the upper end of the anti-fall mechanism via a hollow sleeve.

[0009] The anti-fall mechanism consists of a PLA film, a silica gel layer, a foam material layer, and a buffer layer; the outer wall of the PLA film has anti-slip textures; at the bottom of the anti-fall mechanism, between the inner wall of the PLA film and the outer wall of the silica gel layer, a disc-shaped honeycomb pad layer is provided; the inner wall of the buffer layer is provided with anti-slip protrusions.

[0010] The anti-detachment component includes a slider, a sliding shell, a spring, and a soft rope; the slider is slidably connected to the inner wall of the sliding shell; the spring connects the slider and the sliding shell; the soft rope passes through the slots in the inner wall of the sliding shell and the slots in the outer wall of the slider, and when the slider slides, the slots in the slider can be aligned with or offset from the slots in the sliding shell.

[0011] Preferably, the anti-fall mechanism is arranged in layers from the outside to the inside, with the inner wall of the PLA film attached to the outer wall of the silica gel layer, the inner wall of the silica gel layer attached to the outer wall of the foam material layer, and the inner wall of the foam material layer attached to the outer wall of the buffer layer.

[0012] Preferably, one end of the spring is fixedly connected to the inner wall of the sliding shell, and the other end of the spring is fixedly connected to the bottom of the slider.

[0013] Preferably, the PLA film is a biodegradable material.

[0014] Preferably, the silica gel layer is a negative Poisson's ratio material.

[0015] Preferably, the foamed material layer is a material with a three-dimensional network structure.

[0016] Preferably, the buffer layer is made of pearl cotton and is a recyclable material.

[0017] Preferably, the honeycomb pad has a honeycomb structure.

[0018] Preferably, the shape of the anti-slip protrusions matches the texture of the bottom of the PE bottle.

[0019] Preferably, the grooves in the inner wall of the slider and the grooves in the inner wall of the sliding shell are both circular.

[0020] Preferably, the hollow sleeve has a ring-shaped structure.

[0021] This utility model has the following beneficial effects: 1. In this utility model, by setting up a multi-layer composite anti-drop mechanism consisting of a PLA film, a negative Poisson's ratio silica gel layer, a foam material layer and a buffer layer, the problem of the single buffer structure and poor energy absorption effect of the protective sleeve in the prior art, which makes the PE bottle easy to break when it falls, is solved. The technical effect of multi-level synergistic buffering and efficient absorption of impact energy is achieved, which significantly improves the anti-drop performance of the protective sleeve.

[0022] 2. This utility model solves the problem in the prior art that the protective sleeve is not enough to protect the bottom of the bottle from vertical impact, which can easily lead to excessive local stress and damage by adding a disc-shaped honeycomb pad layer to the bottom of the anti-drop mechanism. It achieves the technical effect of effectively dispersing vertical impact force and strengthening the protection of key areas at the bottom. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 5This utility model provides a PE bottle anti-drop buffer protective cover, which aims to solve the problem that the existing protective covers have insufficient buffering performance and are prone to falling off the bottle, resulting in protection failure.

[0027] like Figure 1 As shown, the PE bottle anti-drop cushioning protective cover includes an anti-drop mechanism 1 and an anti-detachment component 2 that passes through and is fixedly connected to the upper end of the anti-drop mechanism 1. The anti-drop mechanism 1 is the main structure that wraps around the PE bottle and provides cushioning protection. The anti-detachment component 2 is used to tighten and fix the anti-drop mechanism 1 to the PE bottle.

[0028] like Figure 2 and Figure 3 As shown, the anti-fall mechanism 1 is a multi-layer composite structure, in which a PLA film 101, a silica gel layer 104, a foam material layer 105, and a buffer layer 106 are stacked sequentially from the outside to the inside. The inner wall of the PLA film 101 is attached to the outer wall of the silica gel layer 104, the inner wall of the silica gel layer 104 is attached to the outer wall of the foam material layer 105, and the inner wall of the foam material layer 105 is attached to the outer wall of the buffer layer 106. Anti-slip textures 102 are provided on the outer wall of the PLA film 101. At the bottom of the anti-fall mechanism 1, between the inner wall of the PLA film 101 and the outer wall of the silica gel layer 104, a disc-shaped honeycomb pad layer 103 is provided. The honeycomb pad layer 103 has a honeycomb structure. Anti-slip protrusions 107 are provided on the inner wall of the buffer layer 106.

[0029] like Figure 4 and Figure 5 As shown, the anti-detachment component 2 includes a hollow sleeve 201, a soft rope 202, a slider 203, a sliding shell 204, and a spring 205. The hollow sleeve 201 has a ring structure and is connected to the upper end of the anti-fall mechanism 1. The soft rope 202 slides through the channel formed by the hollow sleeve 201 and slides through the slots in the inner wall of the sliding shell 204 and the inner wall of the slider 203 in sequence. The outer wall of the slider 203 is slidably connected to the inner wall of the sliding shell 204. One end of the spring 205 is fixedly connected to the inner wall of the sliding shell 204, and the other end of the spring 205 is fixedly connected to the bottom of the slider 203. The slots in the inner wall of the slider 203 and the slots in the inner wall of the sliding shell 204 can be aligned or staggered by the sliding of the slider 203, thereby achieving the loosening or clamping and locking of the soft rope 202.

[0030] The silica gel layer 104 inside the anti-drop mechanism 1 is a key component. The silica gel layer 104 is a negative Poisson's ratio material, which expands laterally when impacted, forming a locking effect and significantly improving the cushioning efficiency. At the bottom of the anti-drop mechanism 1, between the inner wall of the PLA film 101 and the outer wall of the silica gel layer 104, a disc-shaped honeycomb pad layer 103 is specially provided. The honeycomb pad layer 103 has a honeycomb structure and is specially designed to disperse the impact force of the PE bottle when it falls vertically to the entire bottom, effectively reducing the stress at the bottom of the PE bottle and achieving multi-level absorption of impact energy. In addition, multiple anti-slip protrusions 107 are provided on the inner wall of the buffer layer 106. The anti-slip protrusions 107 match the texture of the bottom of the PE bottle and achieve flexible locking of the PE bottle through physical interlocking, ensuring that the PE bottle is relatively fixed inside the protective sleeve, further enhancing the overall anti-drop effect.

[0031] Reference Figure 4 and Figure 5 The anti-detachment component 2 includes a slider 203 whose outer wall is slidably connected to the inner wall of a sliding shell 204. One end of a spring 205 is fixedly connected to the inner wall of the sliding shell 204, and the other end is fixedly connected to the bottom of the slider 203. The inner wall of the sliding shell 204 has a groove, and the outer wall of the slider 203 has a corresponding groove. A soft rope 202 is threaded through the channel formed by the hollow sleeve 201 and slides sequentially through the grooves in the inner wall of the sliding shell 204 and the inner wall of the slider 203. When the user presses the slider 203, the slider 203 overcomes the resistance of the sliding shell 203. The elastic force of spring 205 causes it to slide inward inside the sliding shell 204, making the slot of slider 203 precisely aligned with the slot of sliding shell 204. At this time, the soft rope 202 can slide freely in the channel to adjust the contraction or relaxation of the protective sleeve. Once slider 203 is released, spring 205 immediately rebounds and pushes slider 203 to reset outward, so that the slot of slider 203 is misaligned with the slot of sliding shell 204. Thus, the position of soft rope 202 is firmly locked by mechanical clamping, effectively preventing the protective sleeve from falling off the PE bottle.

[0032] As a preferred embodiment, in order to improve the environmental performance of the product and reduce its carbon footprint, the PLA film 101 is made of a biodegradable material.

[0033] As a preferred embodiment, in order to achieve more efficient energy absorption when subjected to impact, the silica gel layer 104 is made of a material with a negative Poisson's ratio.

[0034] As a preferred embodiment, in order to further disperse the impact force and improve the cushioning performance by utilizing the internal structure, the foam material layer 105 is made of a material with a three-dimensional network structure.

[0035] As a preferred embodiment, in order to reduce the use of virgin plastics and meet the requirements of the circular economy while ensuring flexibility and tear resistance, the cushioning layer 106 is made of pearl cotton, and the material of the cushioning layer 106 is a recyclable material.

[0036] In a preferred embodiment, in order to effectively disperse the impact force in the vertical direction, the honeycomb pad 103 is designed as a honeycomb structure with multiple hollow units.

[0037] As a preferred embodiment, in order to enhance the stability of the bottle body within the protective sleeve and prevent relative slippage, the shape and layout of the anti-slip protrusions 107 are designed to match the bottom texture of a specific type of PE bottle to create an interlocking locking effect.

[0038] In a preferred embodiment, in order to make the soft rope 202 run smoothly and reduce wear, the cross-sectional shape of the grooves in the inner wall of the slider 203 and the grooves in the inner wall of the sliding shell 204 are both circular.

[0039] As a preferred embodiment, in order to uniformly tighten the upper opening of the anti-fall mechanism 1, the hollow sleeve 201 is designed as a closed ring structure.

[0040] Working principle: When a PE bottle needs to be placed into the protective sleeve, the PE bottle is first placed inside the anti-drop mechanism 1. At this time, the bottom of the PE bottle contacts the anti-slip protrusions 107 on the inner wall of the buffer layer 106. Then, the anti-detachment component 2 is operated, and the slider 203 is pressed. The slider 203 slides on the inner wall of the sliding shell 204 and compresses the spring 205, so that the slot on the slider 203 is aligned with the slot on the sliding shell 204. At this time, the soft rope 202 is in a sliding state. Pulling the soft rope 202 causes the hollow sleeve 201 to contract under force, thereby tightening the upper opening of the anti-drop mechanism 1 and tightly wrapping the PE bottle. After releasing the slider 203, the spring 205 rebounds and pushes the slider 203 to reset, so that the slot on the slider 203 is misaligned with the slot on the sliding shell 204. By misaligning and clamping the soft rope 202, the anti-drop mechanism 1 is prevented from falling off the PE bottle. When the protective sleeve containing the PE bottle is subjected to a drop impact, the multi-layered structure of the anti-drop mechanism 1 works together to provide cushioning protection. First, the outermost PLA film 101 absorbs the initial impact, while the inner silica layer 104, as a negative Poisson's ratio material, expands laterally under pressure, forming a locking effect to efficiently absorb impact energy. Next, the three-dimensional network structure of the foam material layer 105 further disperses and absorbs the residual impact force. The innermost buffer layer 106 provides flexible protection for the PE bottle. If the PE bottle falls vertically, the honeycomb pad layer 103 at the bottom disperses the concentrated impact force to the entire bottom, significantly reducing the stress at the bottom of the PE bottle. Throughout the impact process, the anti-slip protrusions 107 on the inner wall of the buffer layer 106 engage with the matching texture on the bottom of the PE bottle, preventing the PE bottle from shifting relative to the bottom of the protective sleeve and ensuring the stability of the protective effect.
