Abstract

A plurality of test slides carrying thereon dry reagents for chemical analysis of fluid samples or a dry porous analysis layer are sandwiched and sealed between a continuous base sheet and a continuous cover sheet at equal intervals. A test slide strip having alternately slide holding portions and slide free portions along its length is thus produced. The spaces between the adjacent test slides are longer than the test slides, whereby the test slide strip can be folded in an accordion shape so that the slide holding portions and slide free portions are alternately superposed. The folded test slide strip is nested in a box like casing having a slot in one side wall thereof adjacent the bottom. The test slides are dispensed from the casing through the slot one by one in order by pulling the leading edge of the test slide strip.

Claims

1. A test slide strip comprising a plurality of quantitative analysis slides for analysis of a component of fluid samples, a continuous base sheet and a continuous cover sheet, said test slides being sandwiched and sealed between the base sheet and the cover sheet at equal intervals with blank portions between adjacent test slides so that the test slide strip has alternately slide holding portions and slide free portions along its length, said slide free portions being longer than the test slide, whereby the slide strip can be folded in an accordion shape so that the slide holding portions and the slide free portions are alternately superposed.

2. A test slide strip as defined in claim 1 in which said quantitative analysis slides are reagent slides for chemical analysis.

3. A test slide strip as defined in claims 1 or 2 in which said base sheet and said cover sheet are of transparent polyethylene film.

4. A test slide strip as defined in claims 1, 2 or 3 in which transverse perforations are provided in said slide free portion along the rear edge of each test slide.

5. A test slide as defined in claim 4 in which additional transverse perforations are provided in said slide free portion along the leading edge of each test slide.
