Detachable dispensing systems for containers are provided that include a handling portion having an outer ring configured to selectively secure and, alternatively, remove the handling portion about a dispensing opening of the container and an inner ring defining a circular aperture within the handling portion, a hollow rigid member slideably disposed within the circular aperture and selectively positionable between a recessed position and, alternatively, an extended position, and an extendible spout at least partially disposed in the hollow rigid member and connected to the hollow rigid member, in which the extendible spout is configured to dispense a pourable material from the container through the distal opening when the handling portion is engaged about the dispensing opening of the container. Material containers are also provided that include a container having a dispensing opening and the detachable dispensing system selectively connected to the container about the dispensing opening. |

1. A detachable dispensing system for a container, the system comprising:
a handling portion comprising an outer ring configured to selectively secure and, alternatively, remove the handling portion about a dispensing opening of the container and an inner ring defining a circular aperture within the handling portion; a hollow rigid member comprising a top end and a base end, the hollow rigid member slideably disposed within the circular aperture and selectively positionable between a recessed position in which the top end is proximate the handling portion and the base end extends away from the handling portion and toward the container and, alternatively, an extended position in which the base end is proximate the handling portion and the top end extends away from the handling portion and the container, the top end comprising a first engaging element for engaging at least a portion of the inner ring of the handling portion and preventing the top end of the hollow rigid member from moving through the handling portion into the container when the hollow rigid member is in the recessed position, and the base end comprising a second engaging element for engaging at least a portion of the inner ring of the handling portion and fixing the hollow rigid member to the handling portion when the hollow rigid member is in the extended position; and an extendible spout at least partially disposed in the hollow rigid member and connected to the hollow rigid member, the extendible spout comprising,
a proximal end and a proximal opening, the proximal end connected to the hollow rigid member,a distal end and a distal opening, the distal end configured to extend from and retract at least partially into the hollow rigid member, anda discharge passage that extends from the proximal opening to the distal opening, wherein the extendible spout is configured to dispense a pourable material from the container through the distal opening when the handling portion is engaged about the dispensing opening of the container. |
