Cage, especially for small experimental animals
First Claim
1. A cage especially well suited for confining experimental animals, comprising:
- (a) horizontally slidingly shiftable enclosure means including a casing for confining an animal, said casing having a vertical side wall;
(b) there being a hole defined in the side wall of the casing;
(c) a water dispenser fixedly connected to a stationary water conduit and having a stationary spout inserted in the casing through the hole therein for supplying water to the confined animal; and
(d) a connector cup of elastic material hermetically and fixedly mounted to the spout of the water dispenser, the connector cup having an open end held against an outer surface of said wall of the casing around said hole, said casing being held in position with the outer surface of the casing in pressed contact with the connector cup;
(e) whereby the enclosure means and the water dispenser can be readily interconnected as the elastic connector cup is pressed against the outer surface of the casing with the shifting movement of the enclosure means toward the water dispenser.

Abstract
A cage well suited for confining and rearing mice, rats and like relatively small animals in a germ free, hygienic atmosphere for experimentation purposes. Included is a boxlike casing with its open top closed by a wirework inner lid and further hermetically closed by a solid outer lid. A water dispenser for feeding the confined animal has a spout extending into the casing through a clearance hole in its wall. For connecting the spout to the casing and for hermetically closing the clearance hole, an elastic connector cup is fitted over the spout and held against the outer surface of the casing wall. An air supply conduit for supplying germ free air into the casing, and an exhaust conduit for drawing air from within the casing, both extending into the casing through additional clearance holes defined therein, also have similar connector cups mounted thereon. All the clearance holes can be hermetically sealed simply as the connector cups are relatively pressed against the casing.

5. A hermetically sealed, ventilated cage for confining experimental animals or the like, comprising:
-
(a) horizontally slidingly shiftable enclosure means including a casing and providing a hermetically sealed space for confining an animal, said casing having a vertical side wall with spaced-apart first, second, and third holes therethrough; (b) water supply means including a stationary spout inserted in the enclosure means through the first hole defined in the casing for supplying water to the confined animal; (c) a first connector cup of elastic material hermetically and fixedly mounted to the spout and held against the vertical side wall of the casing around said first hole so as to hermetically close the first hole; (d) a stationary air supply conduit inserted in the enclosure means through the second hole defined in the casing for supplying air into the hermetically sealed space; (e) a second connector cup of elastic material hermetically and fixedly mounted to the air supply conduit and held against the vertical side wall of the casing around said second hole so as to hermetically close the second hole; (f) a stationary exhaust conduit inserted in the enclosure means through the third hole defined in the casing for exhausting air from the hermetically sealed space; and (g) a third connector cup of elastic material hermetically and fixedly mounted to the exhaust conduit and held against the vertical side wall of the casing around said third hole so as to hermetically close the third hole; (h) said casing being slidingly shifted horizontally so that the casing is held in position with the outer surface of the casing in pressed contact with the connector cup. - View Dependent Claims (6, 7)

8. A cage especially well suited for confining and rearing relatively small experimental animals in a germ free, hygienically favorable environment, comprising:
-
(a) a substantially boxlike casing having an open top, a front wall and a rear wall; (b) an openwork inner lid closing the open top of the casing; (c) a solid outer lid overlying the inner lid and hermetically closing the open top of the casing; (d) an openwork partition depending from the inner lid and dividing the interior of the casing into an animal compartment for accommodating an animal, and a drinking compartment positioned next to the rear wall of the casing; (e) a water dispenser having a spout inserted in the drinking compartment through a first hole formed in the rear wall of the casing in order to supply water to the confined animal; (f) there being an opening in the partition for enabling the animal in the animal compartment to drink water from the spout of the water dispenser in the drinking compartment; (g) a first connector cup of elastic material mounted to the spout of the water dispenser and held against the outer surface of the rear wall of the casing both for connecting the spout to the casing and for hermetically closing the first hole; (h) an air supply conduit inserted in the casing through a second hole formed in the rear wall of the casing in order to supply germ free air into the casing; (i) a second connector cup of elastic material mounted to the air supply conduit and held against the outer surface of the rear wall of the casing both for connecting the air supply conduit to the casing and for hermetically closing the second hole; (j) an exhaust conduit inserted in the casing through a third hole formed in the rear wall of the casing in order to exhaust air from within the casing; and (k) a third connector cup of elastic material mounted to the exhaust conduit and held against the outer surface of the rear wall of the casing both for connecting the exhaust conduit to the casing and for hermetically closing the third hole. - View Dependent Claims (9)

10. A cage especially well suited for confining experimental animals, comprising:
-
(a) enclosure means including a casing for confining an animal in the form of an open top box, and an openwork lid closing the open top of the casing; (b) there being a hole defined in the casing; (c) a water dispenser having a spout inserted in the casing through the hole therein for supplying water to the confined animal; (d) a connector cup of elastic material mounted to the spout of the water dispenser, the connector cup having an open end held against an outer surface of the casing; (e) whereby the enclosure means and the water dispenser can be readily interconnected as the elastic connector cup is relatively pressed against the outer surface of the casing with the movement of either of the enclosure means and the water dispenser toward the other; and (f) an openwork partition depending from the openwork lid and dividing the interior of the casing into an animal compartment for accommodating an animal, and a drinking compartment into which the spout of the water dispenser extends, there being an opening in the partition for enabling the animal in the animal compartment to drink water from the spout of the water dispenser in the drinking compartment.
