热和/或蒸汽启动阀及其方法
摘要：
公开了阀(10)，其可操作响应热由闭合状态自动转换为打开状态。该阀(10)包括：其中具有至少一个开口(12a)的盖(12)；至少一个粘合剂层(32，36)，用于将盖(12)的周边密封于其上放置该阀(10)的食物烹饪包装(20)的壁(22)上；和，响应暴露于热收缩的可变形元件(14)，可变形元件(14)具有当阀(10)处于它的闭合状态时由粘合剂密封的周边，其中可变形元件(14)的收缩拉动可变形元件(14)的周边离开粘合剂密封的位置，从而破坏可变形元件(14)周边周围的密封，并将阀(10)由它的闭合状态转换为它的打开状态。
摘要（英）：

A valve (10) is disclosed which is operable to automatically transition from a closed state to an open state in response to heat. The valve (10) includes: a cover (12) having at least one opening (12a) therein; at least one adhesive layer (32, 36) for sealing a perimeter of the cover (12) to a wall (22) of a food cooking package (20) on which the valve (10) is positioned; and, a deformable element (14) that shrinks in response to being exposed to heat, the deformable element (14) having a perimeter which is sealed by an adhesive when the valve (10) is in its closed state, wherein shrinking of the deformable element (14) pulls the perimeter of the deformable element (14) away from a site where it is sealed by the adhesive, thereby breaking the seal about the perimeter of the deformable element (14) and transitioning the valve (10) from its closed state to its open state.
