PRESSURIZED DISPENSING SYSTEM INCLUDING A PLASTIC BOTTLE AND PROCESS OF MINIMIZING THE FORMATION OF STRESS CRACKS IN A PLASTIC BOTTLE

A pressurized dispensing system including a plastic bottle and a method of minimizing the formation of stress cracks in a plastic bottle that is a part of a pressurized dispensing system. In a methodof manufacturing the pressurized dispensing system, a plastic bottle is filled with a liquid, a valve is crimped onto the plastic bottle, and the plastic bottle is filled with gas so as to pressurizethe plastic bottle. The plastic bottle is supported only in the finish region throughout the liquid filling, valve crimping, and gas filling steps. The filled and pressurized plastic bottle is substantially free of stress cracks. 一种包括塑料瓶的加压分配系统以及最小化在作为加压分配系统的一部分的塑料瓶中形成的应力裂纹的方法。在制造加压分配系统的方法中，用液体填充塑料瓶；将阀门压接在塑料瓶上；并用气体填充塑料瓶以加压塑料瓶。在整个液体填充步骤、阀门压接步骤及气体填充步骤中，塑料瓶仅在瓶口区域得到支撑。被填充及加压的塑料瓶实质上没有应力裂纹。
