Abstract
A recloseable storage bag is disclosed which may include first and second sides having closed sides and an open top. Primary closure members may be provided proximate the top, with a secondary closure element being provided in one of the sides to enable gas to be evacuated from the bag after the primary closure members are closed. The secondary closure member may further include the ability to prevent liquid from exiting the bag therethrough.
Claims32
A recloseable storage bag, comprising:
- a first side having a bottom edge, left edge, right edge, and top edge;
- a second side having a bottom edge, left edge, right edge, and top edge, the bottom edges of the first and second sides being attached, the left edges of the first and second sides being attached, and the right edges of the first and second sides being attached;
- primary closure members provided proximate the top edges of the first and second sides;
- an aperture in at least one of the first and second sides;
- and
- a secondary closure element associated with the aperture, the secondary closure element being porous.
A method of evacuating air from a recloseable storage bag, comprising the steps of:
- providing a bag having first and second sides connected along first and second side edges thereof, the bag further including a top and bottom, the bottom being closed, the top being adapted to open and close using primary closure members provided proximate the top edges of the first and second sides, the bag further including an aperture in at least one of the first and second sides, and a secondary closure element operatively associated with the aperture, the secondary closure element being porous;
- closing the bag using the primary closure members positioned at the top of the sides;
- and
- compressing the bag to force gas out of the bag through the aperture and secondary closure element.
A recloseable storage bag, comprising:
- a first side having a bottom edge, left edge, right edge, and top edge;
- a second side having a bottom edge, left edge, right edge, top edge, and the bottom edges of the first and second sides being attached, the left edges of the first and second sides being attached, and the right edges of the first and second sides being attached;
- primary closure members provided proximate the top edges of the first and second sides;
- and
- means for evacuating gas from the bag after the primary closure members are sealed, the means for evacuating including at least one aperture covered by a porous layer.
