Abstract
A liquid-dispensing container includes a body defining a chamber configured to hold a liquid, a dispensing port in fluid communication with the chamber, and an air-admission passage including a conduit having an internal end in fluid communication with a lower portion of the chamber and an external end opening to the exterior of the body. A removable closure member seals the external end of the conduit during storage and is frangibly removable to admit air into the chamber during dispensing. When the container is oriented for dispensing, incoming air reduces interruptions in liquid flow. The container may include a removable cap for sealing the dispensing port, and the closure member may be resealable after dispensing.
Claims18
A liquid dispensing container comprising:
- a body defining a chamber configured to hold a liquid;
- a dispensing port in the body in fluid communication with the chamber;
- an air-admission passage including a conduit having
- an internal end in fluid communication with a lower portion of the chamber;
- and
- an external end opening to an exterior of the body;
- and
- a removable closure member sealing the external end of the conduit during storage, the removable closure member being frangibly removable to open the air-admission passage to the exterior such that, during dispensing of the liquid through the dispensing port with the body oriented for dispensing, air is admitted through the conduit into the lower portion of the chamber to reduce interruption of liquid flow through the dispensing port.
A method of dispensing a liquid from a container including a body defining a chamber configured to hold the liquid, a dispensing port in the body in fluid communication with the chamber, and an air-admission passage including a conduit having an internal end in fluid communication with a lower portion of the chamber and an external end openable to an exterior of the body, the method comprising:
- opening the external end of the conduit by frangibly removing a closure member that seals the external end during storage;
- and
- dispensing the liquid through the dispensing port with the container oriented for dispensing while admitting air from the exterior through the conduit into the lower portion of the chamber to reduce interruption of liquid flow through the dispensing port.
