Patent CA-2308680-A1 (CA)
Inventor: GALOMB DAVID E
IPC: B65D5/74
Filed: 2000-05-17
Abstract: A package, e.g., carton or box, for a flowable product, e.g., dry cereal. The carton/box has a planar front panel, a planar rear panel, a planar top panel, a planar bottom panel, a pair of planar side panels, and a closure assembly. The upper panel merges with the front panel at a front corner and merges with the rear panel at a rear corner. The upper panel includes two sections, pivotably connected to each other, with one of the sections located contiguous with the front corner and the other contiguous with the rear corner. The upper panel also has a first, e.g., U-shaped, portion arranged to be removed, e.g., torn away, adjacent one of the side panels to form a pouring spout. The closure assembly comprises a first releasably securable connector located adjacent the front corner, and a second releasably securable connector located adjacent the rear corner. The side panels of the package include plural preformed, e.g., weakened, lines located contiguous with the top panel. At least one of the lines in each side panel is severable parallel to the plane of the top panel immediately adjacent the top panel. The other lines in each side panel are foldable. The top panel also has a fold line extending fully thereacross between the two sections making up that panel. The package's spout is arranged to be re-closed by folding the two sections making up the top panel along it's fold line and bringing those portions of the front and rear panels contiguous with the front and rear corners into a confronting relationship with each other, whereupon they become releasably secured to hold the front and rear panels together and to close the spout.

Title: Disturbance-free electromyographic probe
Inventor: SINDERBY CHRISTER
IPC: A61B5/296
Filed: 1999-07-16
Abstract: A myographic probe for detecting an electrical signal produced by a muscle and for reducing the influence of electrode disturbances. The probe includes electrodes and a disturbance reducing interface covering each electrode thereby segragating the electrodes from the muscle. Electrode disturbances include problems such as those related to the motion of the electrodes, changes in the pressure applied to the electrode, and/or intermittent contact with sourrounding tissue. The disturbance reducing interface is ion permeable and is, when dry, less conductive than the electrodes. The disturbance reducing interface may comprise a matrix of permeable material such as a mesh, foam, or other porous materials. The probe may be in the form of a catheter and be advantageously used in a human cavity such as the oesophagus. Another advantage of the invention is the possibility of using electrodes which are different from conventional wound wire electrodes.
