A thin walled, plastic hot-fill container has a closable neck, a shoulder portion situated below the neck, a base, and a body portion connecting the shoulder portion to the base. The body portion includes a label mount area bounded by upper and lower margins having a plurality of vacuum panels with vertical land areas separating each adjacent pair of vacuum panels. Each vacuum panel includes an upper area and a lower area, the upper and lower areas of each vacuum panel being mutually asymmetric and connected by a tapering geometry providing a range of pressure response through varying flexibility without significant movement of the components parts of the vacuum panels.

Abstract:
A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform. The method includes creating a dispensing opening through the closed end of the container body.

An apparatus for applying a uniform liquid coating to selected portions of an outer surface of an object having a convex horizontal cross section and a constant vertical profile is disclosed. An application pad having a surface contoured to approximate the constant vertical profile of the object acts as a liquid reservoir. The object is transported in a rolling contact with the application surface sufficient to ensure uniform application of the liquid to the surface of the object without substantial deformation of the application pad surface. A support for maintaining the application pad in an orientation such that rolling contact with the surface of the object is provided. Liquid is supplied to the application pad in an amount sufficient to wet the application pad surface and uniformly dispense liquid to the outer surface of the object.
