Description

Technical Field

[0001] This utility model relates to the field of glass bottle technology, and in particular to an impact-resistant and crack-resistant glass bottle. Background Technology

[0002] Glass bottles are widely used as liquid packaging containers in beverage, pharmaceutical, and chemical industries, and have good transparency, chemical stability, and recyclability.

[0003] To address this issue, patent CN114477763A discloses an impact-resistant and crack-resistant glass bottle and its preparation method, aiming to solve the problem that the low mechanical strength of glass bottles makes them unsuitable for applications requiring strict mechanical strength. The key technical points are: based on the weight of the composition, the composition contains 55-80 wt% SiO2, 6-20 wt% Al2O3, 10-25 wt% Na2O, 0-6 wt% K2O, 0.1-1 wt% ZrO2, and 0-0.5 wt% CeO2. The glass bottle of the present invention contains specific amounts of SiO2, Al2O3, Na2O, K2O, ZrO2 and CeO2. The glass prepared using this glass composition has a surface stress of 800MPa or more (e.g. 800-850MPa), a stress layer depth of 30μm or more (e.g. 30-35μm), and an impact resistance of 5J or more (e.g. 5-5.6J), exhibiting significantly superior impact resistance. Furthermore, an organic adhesive is coated on the surface of the glass bottle to form an organic adhesive layer, which is then subjected to high-temperature treatment to transform the organic adhesive layer into a protective layer. This protective layer can effectively enhance and protect the surface of the glass bottle, thereby achieving the purpose of improving the strength of the glass bottle.

[0004] The existing technical solutions described above have the following drawbacks:

[0005] Traditional single-layer glass bottles are brittle and easily break due to external forces such as drops and collisions, posing a significant safety hazard. When subjected to stress, cracks in the glass often extend irregularly, which can easily lead to overall structural failure. Insufficient protection in local structures, such as the bottom, neck, and mouth of the bottle, which are prone to stress, lacks effective cushioning structures and are easily damaged when dropped or impacted. Utility Model Content

[0006] The purpose of this invention is to provide an impact-resistant and crack-resistant glass bottle to overcome the shortcomings of existing impact-resistant and crack-resistant glass bottles and their preparation methods.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an impact-resistant and crack-resistant glass bottle, including a bottle body, a bottle cap assembly, a bottle bottom buffer sleeve and a bottle neck buffer sleeve, wherein the bottle body is composed of an inner bottle body layer, a middle buffer layer and an outer bottle body layer, and the inner bottle body layer, the middle buffer layer and the outer bottle body layer are arranged sequentially from the inside to the outside.

[0008] The outer wall of the outer layer of the bottle body is provided with equidistant crack-inducing grooves extending along the outside of the glass bottle. The outer layer of the bottle body generates a predetermined stress distribution path on the glass bottle surface, guiding the crack to expand in a low-risk direction and preventing the crack from spreading out of control.

[0009] The bottle cap assembly is threaded at the bottle opening of the bottle body, and the bottle cap assembly can absorb impact force for cushioning.

[0010] The bottle bottom buffer sleeve is fitted onto the bottom of the bottle body, and the bottle neck buffer sleeve is fitted onto the bottle neck.

[0011] Preferably, the bottle cap assembly includes a cap body, a buffer cavity, an injection port, and an internal thread. The inner wall of the cap body is provided with an internal thread, which engages with the thread on the outer wall of the bottle opening of the bottle body. The buffer cavity is formed in the cap body.

[0012] Preferably, the injection port is located at the top of the buffer cavity, and the molten rubber is injected into the interior of the buffer cavity through the injection port to form the material.

[0013] Preferably, the inner walls of the bottle bottom buffer sleeve and the bottle neck buffer sleeve are fixedly provided with inner ribs at equal intervals, and the inner ribs are inserted into the induced crack groove.

[0014] Preferably, the induced crack groove is designed as an arc-shaped groove, and there are four induced crack grooves in total, which are arranged in a ring array relative to the bottle body.

[0015] Preferably, the inner layer of the bottle body is made of borosilicate glass to improve its high temperature resistance, corrosion resistance and structural stability. The middle buffer layer is a polyurethane elastomer layer to absorb impact energy and alleviate stress transmission between the inner and outer layers of the bottle body. The outer layer of the bottle body is made of tough modified glass containing high borosilicate components to improve the outer layer's impact resistance and crack release capability. The three are fixedly connected by hot pressing composite.

[0016] Preferably, the bottle bottom buffer sleeve and the bottle neck buffer sleeve are made of thermoplastic elastomer material and have flexible shock absorption function.

[0017] Preferably, the bottom of the bottle body has a recessed buffer zone to disperse concentrated stress at the bottom of the bottle.

[0018] The impact-resistant and crack-resistant glass bottle provided by this utility model has the following advantages:

[0019] Through multi-layer composite, the impact resistance is significantly improved. It adopts a three-layer composite structure of inner bottle body, middle buffer layer and outer bottle body, which is fixedly connected by hot pressing to form an integrated protection system. It maintains the transparency and aesthetics of the glass, while effectively improving the overall impact resistance and crack resistance.

[0020] By setting induced crack grooves to guide the crack path and prevent uncontrolled breakage, the induced crack grooves uniformly set on the outer layer of the bottle can form a predetermined stress distribution path when subjected to external impact, guiding the crack to extend along the low-risk direction and avoiding the irregular spread of cracks to the critical pressure-bearing area of ​​the bottle, so as to achieve controllable local damage and no failure of the overall structure.

[0021] Enhanced protection is achieved by incorporating buffer components to cover key areas. The bottle bottom and neck buffer sleeves are made of thermoplastic elastomer material, and the bottle cap assembly has a buffer cavity. The rubber layer filling the buffer cavity can effectively absorb the impact of the bottle mouth, neck, and bottom, which are prone to stress, and prevent local cracking or breakage.

Detailed Implementation

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1-5 The present invention provides an impact-resistant and crack-resistant glass bottle, comprising a bottle body 1, a bottle cap assembly 2, a bottle bottom buffer sleeve 4, and a bottle neck buffer sleeve 5.

[0031] In this embodiment, the bottle body 1 is composed of an inner layer 101, an intermediate buffer layer 102, and an outer layer 103. The inner layer 101, the intermediate buffer layer 102, and the outer layer 103 are arranged sequentially from the inside to the outside. The three layers are fixedly connected by hot pressing to form an integral structure, thereby improving the impact resistance and crack resistance of the bottle body 1.

[0032] The inner layer 101 of the bottle is preferably made of borosilicate glass, which has good high-temperature resistance, corrosion resistance, and chemical stability. The intermediate buffer layer 102 is made of polyurethane elastomer material, which has good toughness and cushioning performance, and can effectively absorb external impact forces and reduce stress transmission between the inner and outer layers. The outer layer 103 of the bottle is made of toughened modified glass containing high borosilicate components, which improves the impact resistance and crack release capability of the outer layer.

[0033] Example 2

[0034] This embodiment also includes: the outer wall of the outer layer 103 of the bottle body is provided with equidistant induced crack grooves 3 extending along the surface of the glass bottle;

[0035] In this embodiment, the crack induction groove 3 adopts an arc-shaped groove design, and there are four of them. The four crack induction grooves 3 are evenly distributed in a ring around the bottle body 1, so that when the bottle body is subjected to external impact, the crack is guided to expand along a predetermined path, preventing the crack from spreading out of control to the critical stress area of ​​the bottle body 1, and improving the overall safety.

[0036] Example 3

[0037] This embodiment also includes: a bottle cap assembly 2 is threadedly connected to the bottle mouth of the bottle body 1. The bottle cap assembly 2 includes a cap body 201, a buffer cavity 202, an injection port 203, and an internal thread 204.

[0038] In this embodiment, the inner wall of the cap 201 is provided with an internal thread 204, which engages with the thread on the outer wall of the bottle mouth of the bottle body 1. The buffer cavity 202 is provided inside the cap 201 and is used to fill rubber material to absorb the external impact force at the bottle mouth. The glue injection port 203 is opened at the top of the buffer cavity 202. The molten rubber is injected into the buffer cavity 202 through the glue injection port 203 and solidified to form an internal buffer layer.

[0039] The bottle bottom buffer sleeve 4 is fitted onto the bottom of the bottle body 1, and the bottle neck buffer sleeve 5 is fitted onto the neck of the bottle body 1. Both the bottle bottom buffer sleeve 4 and the bottle neck buffer sleeve 5 are made of thermoplastic elastomer material and have flexible shock absorption function.

[0040] Inner ribs 6 are fixed at equal intervals on the inner walls of the bottle bottom buffer sleeve 4 and the bottle neck buffer sleeve 5. The size and position of the inner ribs 6 correspond to the induced crack grooves 3 of the outer layer 103 of the bottle body. The inner ribs 6 are inserted into the induced crack grooves 3 to achieve stable positioning of the buffer sleeve and the bottle body. At the same time, when the bottle body is subjected to force, they assist in supporting the groove wall of the induced crack grooves 3, further improving the impact resistance of the structure.

[0041] The bottom of the bottle body 1 has a recessed buffer zone to disperse the concentrated stress at the bottom of the bottle and reduce the risk of cracking or breaking when the bottom of the bottle is impacted.

[0042] With the above structural configuration, the impact-resistant and crack-proof glass bottle of this utility model can significantly improve its impact resistance and crack-proof safety while ensuring the transparency and aesthetics of the bottle.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
