Container for slides

Claim 2

A mounted slide container, comprising a continuous strip of transparent plastic material folded longitudinally to define two bands interconnected along a common folded edge, said bands being joined together at regular intervals along the length of said strips by a series of equally spaced paris of closely adjacent transverse welds extending across said strip only from the longitudinal folded edge to a point a short distance from either longitudinal free opposite edge, so as to define a series of transverse pockets between said side portions, each pocket being closed at one end by said folded edge, and open at the opposite end thereof between said free edges, said edges being separable to allow the insertion of a plurality of mounted slides, in a direction orthogonal to the longitudinal axis of said strip, and a plurality of reference marks having a spacing equal to the spacing between axes of successive transverse pockets, wherein each such reference mark is placed longitudinally between a corresponding pair of said welds.

Claim 3

A mounted slide container as claimed in claim 1, wherein each reference mark is offset laterally to one side of the welds, in the direction of said free edges, so as to be easily machine-readable.

Claim 4

A mounted slide container, comprising a double-wall continuous strip of transparent plastic material comprising two bands joined along one edge and having a free opposite edge, said bands being joined together at regular intervals along the length of said strip by a series of equally spaced pairs of closely adjacent, continuous transverse welds extending across said strip substantially from the joined edge of the bands to a point a short distance from either longitudinal free opposite edge, so as to define a series of transverse pockets extending the whole width of the strip, each pocket being closed at one end by said joined edge of the bands, and open only at the opposite end thereof between said free edges, said edges being separable to allow the insertion of a plurality of mounted slides displaceable from the opening end of the pocket to the opposite end thereof by pushing, whereby new mounted slides can be subsequently inserted into the same pocket, wherein the double-wall continuous strip consists of a single-wall strip folded longitudinally to define the two bands interconnected along the common folded edge, and further comprising a plurality of reference marks having a spacing equal to the spacing between axes of successive transverse pockets, wherein each reference mark is placed longitudinally between a corresponding pair of said welds.

Claim 5

A mounted slide container, comprising a double-wall continuous strip of transparent plastic material comprising two bands joined along one edge and having a free opposite edge, said bands being joined together at regular intervals along the length of said strip by a series of equally spaced pairs of closely adjacent, continuous transverse welds extending across said strip substantially from the joined edge of the bands to a point a short distance from either longitudinal free opposite edge, so as to define a series of transverse pockets extending the whole width of the strip, each pocket being closed at one end by said joined edge of the bands, and open only at the opposite end thereof between said free edges, said edges being separable to allow the insertion of a plurality of mounted slides displaceable from the opening end of the pocket to the opposite end thereof by pushing, whereby new mounted slides can be subsequently inserted into the same pocket, wherein the double-wall continuous strip consists of a single-wall strip folded longitudinally to define the two bands interconnected along the common folded edge, and further comprising a plurality of reference marks having a spacing equal to the spacing between axes of successive transverse pockets, wherein each reference mark is placed longitudinally between a corresponding pair of said welds.

Claim 6

The invention of claim 3, wherein each reference mark is offset laterally to one side of the welds, in the direction of said free edges, so as to be easily machine-readable.
