Antique J.M. Grosvenor & Co. The Konseal Filling and Closing Apparatus
Boston, MASS.
Laboratory, Lynn, Mass.
Description from the National Museum of American History web page -
"Stanislaus Limousin (1831-1887), a pharmacist in Paris, devised a way of encapsulating medicines in water soluble capsules (which he called “cachets”) in the early 1870s. Karl Morstadt, in Prague, introduced a cachet closing apparatus in 1891, later receiving U.S. Patents 582,021 and 648,594. J. M. Grosvenor & Co., the U.S. sales agent for the Morstadt apparatus, used the word Konseal rather than Cachet. An inscription on the lid of the wooden box reads “Konseal Filling and Closing Apparatus / [PATENTED.] / J. M. GROSVENOR & CO. / Boston, Mass., U.S.A.” A paper on the inside of the lid provides instruction for use."
