Abstract

An apparatus for dispensing a disposable polymeric film and applying it to the hand of a user or an object, in which a stream of air drawn into an enclosed inflation chamber through a constricted opening aligned with an open end of the polymeric film inflates the topmost of a stack of polymeric films in the chamber so that a user can readily insert his hand or an object into the polymeric film. After the user has donned the polymeric film on the hand or an object has been placed in the polymeric film, a wall of the chamber is opened to permit the user to readily withdraw his hand or the object from the chamber while the air flow which originally inflated the top-most polymeric film is disrupted. Upon closure of the chamber wall, the re-established air flow automatically inflates the next lower polymeric film in the polymeric film stack to prepare the next polymeric film for receipt of another hand or object.

Claims

1. A polymeric film dispensing apparatus comprising:

an enclosed inflation chamber having;

an unsealed object insertion opening at a first end of the chamber,

an air outlet opening at a second end of the chamber configured to permit air within the chamber to flow out of the chamber,

a polymeric film-stacking region configured to receive a stack of polymeric films, each polymeric film of the stack of polymeric films having at least two film layers, such that each polymeric film in the stack is located with an open end adjacent to the unsealed object insertion opening and a closed end adjacent to the air outlet opening, and

a chamber roof portion arranged at a height above the stack of polymeric films when the stack of polymeric films is in an installed position in the chamber such that a top polymeric film on the stack of gloves is inflated by a flow of air in the chamber from the unsealed object insertion opening to the air outlet opening.

2. The polymeric film dispensing apparatus according to claim 1, wherein

the chamber roof portion is a movable cover configured such that at least a movable portion of the movable cover is movable away from the polymeric film-stacking region.

3. The polymeric film dispensing apparatus according to claim 2, wherein

the movable cover is arranged such that when the movable portion is moved away from the polymeric film-stacking region the air flow in the chamber is disrupted such that the air flow cannot cause inflation of the top polymeric film.

4. The polymeric film dispensing apparatus according to claim 3, wherein

the movable cover includes a lip portion at the unsealed object insertion opening, the lip portion being configured to

decrease an air flow cross-sectional area of the unsealed object insertion opening when the movable cover is in a closed position, and

increase the air flow cross-sectional area of the unsealed object insertion opening when the movable portion of the movable cover moves away from the chamber in response to withdrawal from the chamber of an object inserted into the top polymeric film.

5. The polymeric film dispensing apparatus according to claim 4, further comprising:

an air flow generating device configured to draw air out of the chamber through the air outlet opening at a flow rate sufficient to inflate the top polymeric film.

6. The polymeric film dispensing apparatus according to claim 5, wherein

the air flow generating device is a vacuum-producing fan.

7. The polymeric film dispensing apparatus according to claim 6, further comprising:

a switching device configured to operate the fan to generate the air flow in the chamber.

8. The polymeric film dispensing apparatus according to claim 7, wherein

the switching device is an operator-actuated manual switch.

9. The polymeric film dispensing apparatus according to claim 7, wherein

the switching device is an automatically-actuated switch configured to be actuated when the object hand is at least one of approaching and entering the unsealed object insertion opening.

10. The polymeric film dispensing apparatus according to claim 7, wherein

the switching device is a proximity detection device configured to detect the object at least one of approaching and entering the unsealed object insertion opening.

11. The polymeric film dispensing apparatus according to claim 7, further comprising:

an anchor block adjacent to the unsealed object insertion opening,

wherein the anchor block is configured to anchor the stack of polymeric films when the stack of polymeric films is in the installed position in the chamber against motion toward the air outlet opening when the top polymeric film is being inflated by the air flow in the chamber.

12. The polymeric film dispensing apparatus according to claim 1, wherein

the inflation chamber includes at least two polymeric film inflation chambers disposed proximate each other in an arrangement which permits simultaneous insertion of a plurality of objects into the at least two polymeric film inflation chambers.

13. The polymeric film dispensing apparatus according to claim 12, wherein

the chamber roof portion includes a movable portion is movable away from the polymeric film-stacking region, and

the movable portion is one of a single cover portion covering at least a portion of the at least two polymeric film inflation chambers or a plurality of cover portions arranged to permit one of the plurality of cover portions over one of the at least two polymeric film inflation chambers to be moved away from the one of the at least two polymeric film inflation chambers independently others of the at least two polymeric film inflation chambers.
