A self-closing squeeze container. A resilient curved plastic rib of a degree of flexibility which is used to tighten the mouth of the container with a suitable resilient return force of the rib. The rib is fastened to the ends of the mouth to keep the mouth closed under its own tension which can be overcome when the container is squeezed by hand strongly enough to flex the rib but not enough to stretch the mouth. This is done by using the force needed to retain the rib's resistance to being straightened out. Examples are given in collapsible and stand-up flexible containers including flip-top types, smooth-opening types, and audible, including audible-'snap'-action, varieties using the idea.

Curved semi-rigid plastic rib closure for flexible containers

An automatic closure for collapsible tubes, squeeze bottles, and the like containers of the type formed from resilient plastic material. The container typically is tubelike, provided with a tapered or frusto-conical neck portion terminating in a flattened mouth defining end lips forming an openable closure. Pressure applied to the body of the container remote from the lips to forms a transverse pinch-off across the end portions wherein the lips are deflected or bent along a line of curvature to one side or the other and at an angle to the axis of the container, and wherein the lips are also bowed, having a curved contour. Such pinch-off forms a closure across the neck portion. The pinch-off opens in response to pressure on the walls of the container proximate thereto in a manner to relive the pinch-off and permit the fluid contents to flow. Specifically, the pinch-off is in the following form: the end lips of the neck have a bowed contour about the lengthwise dimension. The neck is deflected or bent laterally at an angle. The pinch-off is at the line of deflection of the bowed end lips. Along this line (pinch-off) the lips are held together in sealing relationship but they will respond to open and release fluid upon exertion of pressure at a predetermined key area adjacent to the pinch-off line.

A single tool carrier reciprocatingly driven in opposite directions by a pair of double ended reciprocating pneumatic pistons, one of the pistons driving the carrier through rack and pinion gear means and the other piston driving the carrier through a pin integrally connected to the carrier, mounted vertically on the carrier and engaging the said other piston. Seal rings, preferably of Teflon, are mounted on both ends of both pistons. The pistons operate in opposite directions. One piston is made relatively light so that its weight and the weight of the other shoe are counterbalanced against each other.

An integrated apparatus or device for transferring, that is, pumping water from a water bottle to a water fountain having a reservoir with a dispensing faucet. A housing is provided carrying a stopper for insertion into the neck of a water bottle. Within the housing, there is a pump; a tube is connected to the pump discharge and extends through the stopper for pumping air into the bottle. A further tube passes through the stopper for transferring water from the bottle. The other end of this tube extends to fitting means which can be placed on the reservoir in a position normally occupied by the water bottle in an inverted position. This fitting carries a float valve which closes the end of the supply tube when the reservoir is filled.
