Discussion on sealing technology of bottle cap
The issue of sealing the mouth of a bottle is a challenging one that many have tried to address. The problem lies in the fact that only the neck area is sealed, while the threaded portion remains exposed. From production through to the consumer’s drinking experience, various factors can lead to contamination of the bottle’s threaded section. For example, during the filling of beverages like fruit juices or other nutrient-rich drinks, liquid may splash onto the threaded part of the bottle’s neck. Over time, bacteria and air exposure can cause mold growth and discoloration on the threads. Additionally, poor storage or transportation conditions can also lead to contamination, such as when bottles are stored in icy environments for extended periods.
Many consumers have encountered dirt or residue on the threads after opening the cap. Once the cap is removed, it's too late to do anything about it, so they often just accept the situation. In terms of drinking habits, most people don’t use straws when drinking from plastic bottles, and instead, directly place the bottle’s mouth in their mouth. This means any contaminants on the threads could end up inside the body. This issue is especially concerning for children, who are more likely to be affected by this kind of contamination.
Many beverage manufacturers are aware of this challenge and have implemented various solutions, such as controlling fill levels, reducing vibration during the capping process, and cleaning the bottle before sealing. However, the problem still occurs occasionally, and current methods aren’t fully effective. For instance, hot filling requires full liquid level and overflow, which creates a contradiction. Defect rates can sometimes exceed 1%, leading to internal product recalls. Moreover, contamination during transport and retail is hard to manage, resulting in products reaching consumers with issues, causing complaints and damaging brand reputation.
From the analysis of the root causes, the main issue is the lack of proper sealing on the threaded part of the bottle’s mouth. While some food packaging includes protective elements—like the rubber cover on eight-treasure porridge cans—these add-ons often have limited sealing effectiveness and increase costs. Plastic beverage bottles currently lack such protective features. Is there a simple and cost-effective solution?
We propose an improved approach. There are two main types of seals used in plastic beverage bottles: top-seal caps (one-piece or two-piece) and inner plugs. The top-seal cap uses a gasket that deforms under pressure from the bottle’s neck to create a seal. The inner plug, on the other hand, relies on an interference fit between its outer diameter and the inner diameter of the bottle. These two methods work differently, with the gasket cap better suited for pressurized bottles, commonly used in carbonated drinks. The inner plug is typically found in non-carbonated or low-pressure bottles, such as many hot-filled beverages, where sealing depends on the fit between the plug and the bottle neck, along with the material used.
From a production standpoint, the inner plug is simpler to manufacture, cheaper, and maintains consistent reseal performance, making it popular for non-carbonated drinks. Its sealing mechanism doesn’t rely on the final tightening torque of the cap, which is mainly used to prevent accidental loosening. Therefore, improving the inner plug’s sealing ability can effectively solve the issue of thread contamination at the bottle’s mouth.
