Patent JP-H085115-B2 (JP)
IPC: B29C49/02
Filed: 1988-02-12
Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension. Following the extrusion, the molding extension is advanced downward, in the embodiment illustrated, and serves as an implement for forming the inner shape of the reduced-diameter region or regions of the body part, and as an opposing thrust element for the blow-mold pieces which press together a region or regions of the tubular preform segment.

Abstract: A tamper indicating package (20) comprising a one-piece molded closure (23) of plastic which threads onto a container (21) such that when the closure is unthreaded, a tamper-indicating ring (28) becomes separated from the lower end of the closure skirt. The indicating ring or band (28) is joined to the closure along a weakened frangible line and a flexible stop ring (31) is formed within the band (25) and extends inwardly and upwardly when the closure is applied to a container finish. The container finish (22) has a first radial bead (37), a second radial bead (39) spaced axially below the first bead (36), and an intermediate tapered or concave surface between the first radial bead and second radial bead. A further surface (41) extends from the second bead (39) axially downwardly and radially inwardly and the flexible end of the stop ring (3) rests on this surface between the two beads, when the closure is applied. When the closure is unthreaded to remove it, the free end (32) of the stop ring (31) passes over the second bead (39) into the recess formed by the surface between the two beads and the frangible portion (29) is broken leaving the ring and band in this position. Upon subsequent reapplication of the closure (12), the closure skirt (25) engages the band (28) causing the band to pass over the second bead (39) on the finish so that the band falls away but remains on the container to indicate that the band has been severed.

Abstract: The glycosides of resorufin derivatives have the general formulae Ia and Ib <IMAGE> in which R<1> is hydrogen, R<2>, R<3> and R<5>, which can be identical or different, are hydrogen, halogen or a lower alkyl group, R<4> and R<6>, which can be identical or different, are hydrogen, halogen, a cyano, lower alkyl, lower alkoxy, carboxyl, lower alkoxycarbonyl, carboxy-lower alkyl, lower alkoxycarbonyl-lower alkyl or an optionally mono- or disubstituted carboxamide group or the group  -COO-(CH2CH2O)n-R<7> in which R<7> is hydrogen or a lower alkyl group and n is an integer from 1 to 4, where R<6> can additionally be a sulphonyl or nitro group, and Y is a nitrogen or the group NO. These compounds are particularly suitable as chromogenic and fluorogenic substrates for determining the activity of corresponding glycosidases or oligosaccharide-cleaving enzymes. The glycosides are obtained by reacting resorufin derivatives with a mono- or oligosaccharide or a 1-halogeno derivative thereof, whose hydroxyl groups are substituted by customary protective groups. This initially results in per-O-substituted glycosides, which can be converted into the claimed compounds by elimination of the protective groups. The glycosides are used as chromogenic and fluorogenic substrates in diagnostic agents for detecting glycosidases or oligosaccharide-cleaving enzymes. The resorufin derivatives employed as starting materials in the preparation of the compounds are also claimed.
