Closure means for pneumatic carrier

Claim 2

For use in a pneumatic tube system, an elongated hollow carrier, said carrier being open at one end thereof and having a closed second end, an article receiving liner slidably insertable into and removable from said carrier, said liner having an inner end and an outer end, fastening means having cooperating components on said liner and said carrier for effecting a releasable securing of said liner within said carrier upon a longitudinal sliding of said liner into said carrier and a positioning of the inner end of said liner juxtaposed the second end of said carrier, said fastening means including a spring loaded retainer on said second end of the carrier and pin-like projecting member means arrangEd on the inner end of said liner and extending in the elongated direction of the carrier for a selective snap locking of the retainer to the member, and manipulating means comprising a finger receiving hole surrounded by resiliently flexible flaps which engage and grip an inserted finger so as to releasably secure the liner to the finger.

Claim 3

The invention of claim 1 wherein said retainer and said member are centrally located and engageable regardless of the rotational position of the liner within the carrier.

Claim 4

The invention of claim 1 wherein said retainer is slidably releasable from said member.

Claim 5

The invention of claim 1 wherein said member includes a peripheral recess thereabout, said retainer engaging within said recess.

Claim 6

The invention of claim 1, wherein said spring loaded retainer includes a plate provided with a pear-shaped opening with one end having a diameter substantially the same as a mating portion of said member, and a spring normally biasing said plate toward engagement with said member.

Claim 7

For use in a pneumatic tube system, an elongated hollow carrier, said carrier being open at one end thereof and having a closed second end, an articles receiving liner slidably insertable into and removable from said carrier, said liner having an inner end and an outer end, fastening means having cooperating components on said liner and said carrier for effecting a releasable securing of said liner within said carrier upon a longitudinal sliding of said liner into said carrier and a positioning of the inner end of said liner juxtaposed the second end of said carrier, said fastening means including a spring loaded retainer on said second end of the carrier and pin-like projecting member means arranged on the inner end of said liner and extending in the elongated direction of the carrier for a selective snap locking of the retainer to the member, liner gripping and manipulating means at the outer end of the liner, said gripping and manipulating means being within the confines of said liner, said gripping and manipulating means comprising a finger receiving hole surrounded by resiliently flexible flaps which engage and grip an inserted finger so as to releasably secure the liner to the finger.

Claim 8

For use in a pneumatic tube system, an elongated hollow carrier, said carrier being open at one end thereof and having a closed second end, an articles receiving liner slidably insertable into and removable from said carrier, said liner having an inner end and an outer end, fastening means having cooperating components on said liner and said carrier for effecting a releasable securing of said liner within said carrier upon a longitudinal sliding of said liner into said carrier and a positioning of the inner end of said liner juxtaposed the second end of said carrier, said fastening means including a spring loaded retainer on said second end of the carrier and pin-like projecting member means arranged on the inner end of said liner and extending in the elongated direction of the carrier for a selective snap locking of the retainer to the member, liner gripping and manipulating means at the outer end of the liner, said gripping and manipulating means being within the confines of said liner, said gripping and manipulating means comprising a finger receiving hole surrounded by resiliently flexible flaps which engage and grip an inserted finger so as to releasably secure the liner to the finger.

Claim 9

For use in a pneumatic tube system, a hollow carrier open at a one end thereof and closed at the other end, an article receiving liner clidably insertable into and removable from said carrier through the open end, said liner having an inner end, fastening means having cooperating components on the liner inner end and the carrier closed end for effecting a releasable securing of said liner within said carrier upon an insertion of said liner into said carrier, said liner having an outer end positionable in general alignment with the open end of the carrier upon an insertion of the liner into the carrier, said liner gripping and manipulating means separate from the fastening means and arranged on the outer end portion of the liner for selectively withdrawing same from said carrier, said gripping and manipulating means comprising a finger receiving hole surrounded by resiliently flexible flaps which engage and grip an inserted finger so as to releasably secure the liner to the finger.

Claim 10

For use in a pneumatic tube system, a hollow carrier open at a one end thereof and closed at the other end, an article receiving liner clidably insertable into and removable from said carrier through the open end, said liner having an inner end, fastening means having cooperating components on the liner inner end and the carrier closed end for effecting a releasable securing of said liner within said carrier upon an insertion of said liner into said carrier, said liner having an outer end positionable in general alignment with the open end of the carrier upon an insertion of the liner into the carrier, said liner gripping and manipulating means separate from the fastening means and arranged on the outer end portion of the liner for selectively withdrawing same from said carrier, said gripping and manipulating means comprising a finger receiving hole surrounded by resiliently flexible flaps which engage and grip an inserted finger so as to releasably secure the liner to the finger.
