Sterile needle package

Claim 2

A needle package comprising a cartridge having a stiff elongated tubular body closed at its lower end and open at its upper end, a removable cap closing said open upper end, and a needle loosely supported within said cartridge, said needle having a sharpened tip portion at its lower end and an enlarged hub at its upper end, said cartridge body being provided with an internal ledge spaced below the body's upper end and engaging the underside of said hub to support said needle with the tip portion thereof spaced from the bottom of said body, said body also being provided with an enlarged compartment enclosing said tip portion and a relatively narrow neck portion directly above said compartment, said neck portion being engagable with said needle above said tip portion to prevent said tip portion from engaging the inside surface of said compament.

Claim 3

The needle package of claim 1 in which said internal ledge is spaced below the body's upper end a distance no less than the approximate axial length of said hub.

Claim 4

The needle package of claim 1 in which said cartridge body is provided with an outwardly projecting annular shoulder spaced below the open upper end thereof, said cap having a lower edge joined to said shoulder.

Claim 5

The needle package of claim 3 in which said cap is also provided with a lever hingedly connected to said cap along a hinge line extending in a plane substantially normal to the axis of said cartridge and spaced outwardly from said axis, said lever having a handle portion disposed outwardly beyond said hinge line and movable between a lowered position nd a raised position, said lever also having a lug portion disposed inwardly of said hinge line and movable downwardly into engagement with said shoulder, as said handle portion is raised, to pry said cap free from said body.

Claim 6

The needle package of claim 4 in which said handle portion has a length substantially greater than said lug portion as measured from said hinge line.

Claim 7

The needle package of claim 4 in which said lug portion also projects upwardly above said hinge line, said lug portion above said hinge line being engagable with said cap to limit upward movement of said lever about said line and to cause a lifting of said cap from said body as continued upward force is exerted upon said handle portion.

Claim 8

The needle package of claim 1 in which said cartridge body and said cap are formed from relatively rigid plastic material.

Claim 9

A needle package comprising a cartridge having a tubular body open at its upper end and adapted to support a sterile needle therein, said body having an annular shoulder spaced below the open upper end thereof and projecting outwardly from said body, and a cap fitting over the open upper end of said body and having a lower edge joined to said shoulder, said cap being provided with a lever hingedly connected thereto along a line extending in a plane substantially normal to the axis of said cartridge and spaced outwardly from said axis, said lever having a handle portion disposed outwardly beyond said hinge line and movable between a lowered position and a raised position, said lever also having a lug portion disposed inwardly of said hinge line and movable downwardly into engagement with said shoulder to pry said cap free from said body when said handle portion is raised.

Claim 10

A needle package comprising a cartridge having a tubular body open at its upper end and adapted to support a sterile needle therein, said body having an annular shoulder spaced below the open upper end thereof and projecting outwardly from said body, and a cap fitting over the open upper end of said body and having a lower edge joined to said shoulder, said cap being provided with a lever hingedly connected thereto along a line extending in a plane substantially normal to the axis of said cartridge and spaced outwardly from said axis, said lever having a handle portion disposed outwardly beyond said hinge line and movable between a lowered position and a raised position, said lever also having a lug portion disposed inwardly of said hinge line and movable downwardly into engagement with said shoulder to pry said cap free from said body when said handle portion is raised.

Claim 11

The needle package of claim 8 in which said cap is fused to said body at a plurality of points spaced circumferentially about said shoulder.

Claim 12

The needle package of claim 8 in which said handle portion has a length substantially greater than said lug portion as measured from said hinge line.

Claim 13

The needle package of claim 8 in which said cap has top and side walls, said lug portion of said lever also projecting upwardly above said hinge line for engagement with the side wall of said cap when said lever is in its raised position, thereby limiting further upward movement of the handle portion of said lever about said hinge line.

Claim 14

The needle package of claim 8 in which said cap and cartridge body are formed of relatively rigid plastic material.

Claim 15

The needle package of claim 8 in which a hub-equipped needle is loosely supported within said tubular body.

Claim 16

The needle package of claim 13 in which said cartridge body is provided with a bottom wall spaced below the tip of said needle, and means disposed within said cartridge body above the tip of said needle for preventing contact between said tip and the interior of the tubular body.

Claim 17

The needle package of claim 13 in which said needle includes a hub portion supported within said body adjacent the open upper end thereof, said hub havng its upper limits at substantially the same level as the upper opening of the cartridge body.
