1,250,496. Decorating confectionery. J. MACMANUS. 19 Dec., 1969 [31 Dec., 1968], No. 61985/68. Heading A2A. In appartus for decorating or filling confectionery of the kind in which a succession of units of confectionery, e.g. pastries or cakes, travels on a conveyer belt past a position where a stiff fluent aerated product, e.g. whipped cream, is extruded on to them from a nozzle, usually secured to a savoy bag manipulated by an operator and fed continuously by a hose, the nozzle is fed by a disposable hose and forcing bag which are formed integrally with one another, the bag consisting of a bulbous portion at one end of the hose having an unobstructed discharge outlet. In the embodiments, the base 8 is a PVC extrusion and has a wire helix surrounding it to prevent kinking. The hose is detachably secured to a duct 13 by a screw connector (Fig. 2, not shown). The bag portion 9 is formed by blow moulding and preferably comprises a shorter divergent portion 10 and a long tapering portion 11 terminating in a straight outlet throat 12. In the embodiments of Figs. 1 and 4, the nozzle is engaged by co-operating flanges in the lower end of a tube (19, Fig. 3, not shown) which is pushed up into the throat 12, the assembly being secured by an internally threaded collar (22) engaged over the throat and co-operating with a thread formation on the tube (19). Where remote operation of the bag is desired, an inflatable ring 23 contained in a retaining ring 24 surrounds the portion 11 of the bag and is inflated and deflated through a pipe 25 to squeeze the bag intermittently. An expansion chamber formed by a flexible sausage-like member 26 secured over a perforation in the bag may be provided to vent air from the bag via an orifice 28. In the embodiment of Fig. 5, an outer bag 31 surrounds an inner bag 9A, so that an insulating layer of air 34 is provided, vented via apertures 33. In this case, the outer bag, and the inner bag plus hose, are each formed from two plies of sheet material secured together by two heat welded seams 32, 30, respectively, and the nozzle 18A is secured by a band 35 sprung into place. In a further embodiment, (Fig. 7, not shown), the bag is of tubular form, the lower end being constructed slightly and adapted to be rolled over the nozzle to secure the latter in position.
