Patent Searching and Data


Title:
スロットベント開口を有するテストストリップ
Document Type and Number:
Japanese Patent JP2007524822
Kind Code:
A
Abstract:
Methods of manufacturing test strips are disclosed. Embodiments include laminating a two piece covering layer over a substrate with a series of cavities, wherein the two pieces are separated by a gap, the gap forming a vent opening for the cavities. Other embodiments include covering the sample receiving chamber with a cover thinner than the cover covering the body of the test strip, the thicker body cover absorbing more force than the chamber cover to reduce the possibility of adhesives squeezing out from under the chamber cover. The present invention also provides an advantageous method of mass-producing the inventive test strips without having to align the slot or vent opening laterally with respect to the test strips and without having to punch a vent opening. The method is also well suited to mass production by roll processing techniques.
