Abstract
Abstract A procedure for loading into an instrument cuvettes intended for chemical analysis and/or handling of liquids, said cuvettes being loaded into the instrument directly from the shipping package, and a cuvette package. The cuvette package includes a box portion for supporting the cuvettes having an open feeding end, and a cover portion detachable from the box portion and provided with a depending pushing member. When the cover portion is disposed contiguously atop the box portion to form the package, the pushing member closes the feeding end to securely contain any cuvettes therein. When the cover portion is detached from the box portion, dust-free and scratch-free transfer of cuvettes into the instrument while the package is attached to an input aperture of the instrument may be accomplished by pushing, from behind, the rows of cuvettes in the package with the pushing member of the cover portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
A procedure for loading into an instrument cuvettes intended for chemical analysis and/or handling of liquids, said cuvettes being arranged in at least one row in a shipping package having a detachable cover and being loaded in a forward direction into an input aperture of the instrument directly from the shipping package, comprising: transferring the cuvettes into the instrument by pushing the cuvettes in the package from behind with the detachable cover of the package, the cover being provided with a separate pushing member which, when the cover is contiguous with the package, forms one end of the package.
Claim 2
Dependent Claim
99 words
A procedure for loading into an instrument cuvettes intended for chemical analysis and/or handling of liquids, said cuvettes being arranged in at least one row in a shipping package having a detachable cover and being loaded in a forward direction into an input aperture of the instrument directly from the shipping package, comprising: transferring the cuvettes into the instrument by pushing the cuvettes in the package from behind with the detachable cover of the package, the cover being provided with a separate pushing member which, when the cover is contiguous with the package, forms one end of the package.
Claim 3
Dependent Claim
58 words
The procedure according to claim 1, and further comprising: providing projections on the pushing member, and moving the cuvettes in the package with point or line contact by interposition of said projections provided on the pushing member behind the cuvette adjacent to the pushing member, said projections being directed against partitions between different reaction vessels in said cuvette.
Claim 4
Dependent Claim
97 words
The procedure according to claim 1, wherein the package has a forward end, and opposite rear end and sides, the forward end being narrower than the rear end, whereby cuvettes in the forward end are compressed against the sides of the package thereby holding the cuvettes in place unless pushed by the pushing member, and further comprising: halting the transferring of the cuvettes into the instrument before all of the cuvettes in the package have been transferred into the instrument, and moving the remaining cuvettes rearwardly back into the package with the pushing member on the cover.
Claim 5
Dependent Claim
136 words
A cuvette package adapted for feeding liquid-containing cuvettes to be carried in the package into an instrument for chemically analyzing and/or handling the contained liquid, the package comprising: a box portion for supporting the cuvettes and having a bottom, upstanding opposing sides, an upstanding front end and an open feeding end, and a cover portion placed atop, and detachable from, the upstanding opposing sides of said box portion, said cover portion including a top, sides, and an end having a downwardly depending pushing member which closes the feeding end of the box portion to securely house the cuvettes to be contained therein, said detachable cover portion and pushing member defining a tool for pushing the cuvettes into an instrument when said cover is detached and said package is attached to an input aperture of the instrument.
Claim 6
Dependent Claim
136 words
A cuvette package adapted for feeding liquid-containing cuvettes to be carried in the package into an instrument for chemically analyzing and/or handling the contained liquid, the package comprising: a box portion for supporting the cuvettes and having a bottom, upstanding opposing sides, an upstanding front end and an open feeding end, and a cover portion placed atop, and detachable from, the upstanding opposing sides of said box portion, said cover portion including a top, sides, and an end having a downwardly depending pushing member which closes the feeding end of the box portion to securely house the cuvettes to be contained therein, said detachable cover portion and pushing member defining a tool for pushing the cuvettes into an instrument when said cover is detached and said package is attached to an input aperture of the instrument.
Claim 7
Dependent Claim
27 words
A cuvette package according to claim 4, wherein said pushing member includes projections which serve as contact points between the pushing member and a cuvette closest thereto.
Claim 8
Dependent Claim
75 words
A cuvette package according to claim 4, wherein the sides of the cover portion and the box portion include complementarily configured means for vertically detaching and reattaching said cover portion and said box portion, said complementarily configured means coacting to press said cover portion to said box portion and to permit longitudinal sliding movement of said cover portion relative to said box portion when said cover portion and pushing member are used as said tool.
Claim 9
Dependent Claim
63 words
A cuvette package according to claim 4, wherein the sides at the feeding end of said box portion are narrower than the sides at the front end whereby the cuvettes are compressed against the sides of the package at the feeding end so that a cuvette that has been left at the feeding end remains in place without falling out of the package.
Claim 10
Dependent Claim
15 words
A cuvette package according to claim 4, wherein the package is made of shock-resistant polystyrene.
Claim 11
Dependent Claim
44 words
The cuvette package of claim 4, wherein said box portion front end includes chamfered means for facilitating insertion of the pushing member into the box portion forwardly of the cuvettes so that the cuvettes can be pushed into the instrument from said box portion.
