Abstract
Vacuum release systems that allow rapid, uninterrupted flow of a liquid through a first opening in a container when the container is inverted are disclosed. The vacuum release systems include a hole punch and can be secured to the outer surface of the container. When the liquid-filled container is inverted, pressure is applied to the hole punch to form a second opening in the side of the container. The second opening releases the vacuum by allowing air to flow into the container, which, in turn, allows rapid, uninterrupted flow of the liquid through the first opening in the container.
Claims7
A vacuum release system comprising:
- a hole punch having a shaft with a tapered end and a head;
- and
- a housing including
- two aligned and opposing first and second openings, and
- at least one first vent located in the housing around the first opening and at least one second vent located in the housing around the second opening, the housing encloses a portion of the shaft disposed within the first and second openings, the head larger than the first opening, and the housing is composed of a flexible material that compresses when a force is applied to the head of the punch to move the punch in a first direction, and when the force is removed the housing is restored to an uncompressed shape to move the punch in a direction opposite the first direction.
A vacuum release system comprising:
- a hole punch having a shaft with a tapered end, a head, and a ring located along the shaft;
- a rear housing having a first opening dimensioned to receive the shaft of the punch;
- and
- a front housing having a second opening dimensioned to receive the shaft, the front housing and rear housing are connected with the first opening aligned with the second opening to form a guide to steady and direct the punch, the punch is oriented with the tapered end toward the rear housing, and the front housing is composed of a compressible material such that when a force is applied to the head of the punch the front housing collapses to allow the punch to move in a first direction, and when the force is removed the housing is restored to an uncompressed shape to move the punch in a direction opposite the first direction.
