Abstract
The present invention relates to an easy-to-use and effective magnetically resealable moisture-proof pouch containing moisture-curable orthopedic splinting/casting product in bulk form or in individually packaged rolls. The preferred pouch incorporates a frame disposed about an opening into the pouch which provides a mounting place for a moisture-proof magnetic seal. Also disclosed are containers for the preferred pouches which are adapted for use with the magnetic sealing system according to the present invention.
Claims24
The combination of moisture-curable orthopedic splinting/casting product in a moisture-impervious, hermetically reseatable pouch, the combination comprising:
- a) a substantially rigid container;
- b) a hermetically sealable pouch located within the container;
- c) a sheet of moisture-curable orthopedic casting/splinting product in the pouch;
- d) an opening in the pouch allowing access to the orthopedic casting/splinting product contained therein;
- e) retaining means for retaining an end of the moisture-curable orthopedic casting/splinting product proximate the opening in the pouch, the retaining means comprising a retaining insert in the pouch proximate the opening, the retaining insert having a slot through which the moisture-curable orthopedic casting/splinting product is threaded to reach the opening;
- f) magnetic sealing means proximate the opening for providing a reseatable moisture-impervious, hermetic seal over the opening, the magnetic sealing means comprising:
- 1) a frame attached to the pouch proximate the opening and hermetically sealed to the pouch, the frame having a substantially planar surface and defining a void in which the opening is located, at least a portion of the frame comprising magnetic material subject to magnetic attraction;
- and
- 2) a moisture-proof cover magnetically attracted to the magnetic material of the frame to seal the void in the frame, the cover being hingedly attached to the combination by at least one hinge, the cover having a first surface facing the frame;
- and
- g) a release plunger movably attached to the cover, the release plunger having first and second ends and being movable between a first position, wherein the first end of the release plunger does not extend out from a plane generally defined by the first surface of the cover, and a second position, wherein the first end of the release plunger extends out from the plane generally defined by the first surface of the cover, thereby engaging the frame and forcing the cover away from the frame.

A container for moisture-curable orthopedic splinting/casting product, the container comprising:
- a substantially rigid outer container;
- a hermetically sealable pouch located within the container, the pouch having an interior and an opening into the interior of the pouch allowing removal of moisture-curable orthopedic splinting/casting product from the interior of the pouch;
- and
- magnetic sealing means proximate the opening of the pouch for providing a moisture-impervious, hermetic seal over the opening, the magnetic sealing means comprising:
- a frame attached to the pouch surrounding the opening of the pouch and hermetically sealed to the pouch around the opening of the pouch, the frame having a substantially planar surface and defining an opening aligned with the opening of the pouch, at least a portion of the frame comprising magnetic material subject to magnetic attraction;
- and
- a moisture-impervious door assembly comprising a door hingedly attached to the frame for movement between an open position providing access to the moisture-curable orthopedic splinting/casting product within the interior of the pouch, and a closed position in which the door covers the openings of the frame and pouch and hermetically seals the openings, the door including magnetic material subject to magnetic attraction with the magnetic material of the frame;
- the door further comprising manually operable release means engageable with the frame to move the magnetic material of the door away from the magnetic material of the frame to release the door from magnetic attraction with the frame.
