Liquid container with integral opening apparatus
First Claim
1. A container for containing a fluid comprising:
- at least one flexible wall defining an internal liquid compartment containing a quantity of liquid;
the flexible wall having a conduit extending therethrough the conduit having an inlet opening extending inside the container and an outlet opening which extends beyond the container;
the conduit having penetrable means located therein for closing the conduit; and
rigid means for penetrating the penetrable means, said rigid means being secured to and located inside the container and aligned to penetrate said penetrable means upon movement of said rigid means and said penetrable means together, said rigid means including a conduit for allowing fluid from inside the container to flow into said conduit in said flexible wall and out a dispensing means secured to the outlet opening.

Abstract
An improved disposable liquid container adapted for infant nursing is provided for maintaining nursing liquid in a sterile or aseptic condition until dispensed therefrom. Rigid penetrating means carried by a semirigid support member penetrate a compartment closing diaphragm to allow nursing liquid to flow from the compartment to a communicating, attached nipple. The semirigid support member is integral with the liquid compartment and substantially preserves its shape as the fluid is dispensed therefrom. Flexible walls of the container are allowed to collapse together as the fluid is dispensed to prevent excessive ingestion of air by a nursing infant. The attached nipple is maintained in a clean, uncontaminated, sterile, or aseptic condition until use by means of separable sealing tabs or a discardable cover. Additional embodiments provide a flexible container which may safely be placed upright on cannula adjacent said generally sharpened tip portion to allow fluid to flow through said flow passageway when said tip portion penetrates said penetrable means.

10. A container for containing a fluid comprising:
-
at least one flexible wall defining an internal liquid compartment containing a quantity of liquid, the flexible wall having a conduit extending therethrough, the conduit having an inlet opening extending inside the container and an outlet opening which extends beyond the container, the outlet opening is secured to a dispensing means for dispensing the fluid outside the container, the conduit having penetrable means located therein for closing the conduit; and an elongated rigid means for penetrating the penetrable means, said rigid means being supported by a semi-rigid support member located within the container, said rigid means is partially received by the conduit in said flexible wall so that the rigid means can penetrate the penetrable means upon movement of said rigid means and said penetrable means together, and said rigid means includes a conduit for allowing fluid from inside the container to flow into the conduit in said flexible wall. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
