Abstract
The invention relates to a miniaturized fluid container with microchannels (11, 12) which are bordered by ridges (13, 14), wherein the crests of the ridges (13, 14) are glued to a cover plate (20). Additional stability may be achieved by distributing glue (33) in cavities between the microchannels (11, 12), the spreading of said glue being driven by capillary forces.
Claims9
Miniaturized fluid container, comprising
- a) a structured plate with at least two neighboring ridges, each having a flat crest, and each projecting from one side of the plate with said crests lying at the same height (h) and which define a microchannel between them;
- b) a cover plate that it is attached to the structured plate and contacts the at least two ridges at their crests;
- wherein the mean width (d) of the ridges is 0.1 to 10 times their mean height (h);
- and,
- wherein the contact region between the cover plate and the crests is embedded in a sealing material, preferably in a glue, and
- wherein at least one cavity between the structured plate and the cover plate is filled with a glue.
A method for manufacturing a miniaturized fluid container, comprising the following steps:
- a) preparing a structured plate with at least two neighboring ridges, each having a flat crest, and each projecting from one side of the plate with said crests lying at the same height (h) and which define a microchannel between them;
- b) providing a cover plate;
- c) assembling the structured plate and the cover plate such that the crests of the ridges contact the cover plate;
- wherein the mean width (d) of the ridges is 0.1 to 10 times their mean height (h);
- wherein a glue sealing material is applied to the crests of the ridges of the structured plate;
- and,
- characterized in that at least one cavity between the structured plate and the cover plate is filled with a glue.

- and,
- d) sealing the contact region between the cover plate and the crests by ultrasonic bonding;
- e) filling at least one cavity between the structured plate and the cover plate with a glue.

- wherein the ridge mean width is narrow relative to the width of the structured plate;
- and,
- b) a cover plate that it is attached to the structured plate and contacts the at least two ridges at their crests;
- wherein the contact region between the cover plate and the crests is embedded in a sealing material, preferably in a glue;
- and,
- wherein at least one cavity between the structured plate and the cover plate is filled with a glue.
