Patent CA-2148966-A1 (CA)
Inventor: SCHELIGA WERNER
IPC: B29C45/40
Filed: 1995-05-09
Abstract: A molded cap for sealing a container, and having a core-profiled internal skirt portion is injection molded within a seamless annular cavity mold, wherein segmentation of the interior core die portion bearing the internal form such as a screw thread form for the inside of the cap skirt, permits its inward withdrawal clear of the cap after completion of the injectioncycle. Due to the seamless mold cavity the cap has no externally visible mold witness lines along its skirt. The molded cap contracts radially as it cools within the mold, permitting molded parts and decorative features that are on or in the skirt face to withdraw radially inwardly from the mold surfaces, such that the cap can be ejected clear from the mold without damage to fine detailed or hang-up on undercuts into the mold skirt face.

Patent CA-2172620-A1 (CA)
Inventor: HAMMOCK BRUCE D
IPC: G01N33/543
Filed: 1994-11-16
Abstract: The present invention provides methods for assaying for a metal ion in a sample. In one aspect, the present invention relates to an enzyme amplified sandwich assay. This method relies upon the ability of the metal ion to form a complex with two chelators. Such an association is termed a sandwich complex with the metal ion forming the middle of the sandwich. In this method the first chelator is immobilized on a solid support, while the second chelator is linked to a reporter group. This arrangement forms a highly selective, sensitive, and convenient system for the quantitative, detection of metal ions. This approach combines the specific recognition of the metal ion by the first and second chelators, with the great signal amplification offered by enzymes or other reporter groups. In another aspect, the present invention relates to a competitive assay that relies on the competitive inhibition of complex formation between a chelator immobilized on a solid support and an organometallic compound attached to a reporter group, by the metal ions of interest in a sample.
