Abstract
Abstract Hollow confectionery articles are manufactured by injecting a flowing confectionery material into an open mould, usually consisting of a series of recesses pressed in a thin sheet of synthetic resin. It is desirable that the confectionery material shall not be permitted to smear the upper surface of the mould between the recesses. The injection is brought about by means of an apparatus having a head extending into the recess during the filling operation, and being tightly pressed against the mould around the recess being filed. The head is provided with a cavity for surplus confectionery material, and compressed air is injected into the recess together with the confectionery material to augment the uniform spreading of the confectionery material over the walls of the recess and to force the surplus into the cavity to be collected in a container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
An apparatus for molding confectionery in open molds comprising at least one open mold; a confectionery molding device for each open mold, each device including confectionEry passage means for supplying settable fluid confectionery to be sprayed in the open mold; a compressed air passage means terminating in the open mold, a spray head operatively connected to said two passage means for sealingly engaging the peripheral edge portion of the open mold, and cavity means in the spray head juxtaposed said edge portion so that the compressed air augments in forming a uniform layer of the sprayed confectionery in the open mold, the excess confectionery being removed from the open mold through said cavity means along with the compressed air.
Claim 2
Independent Claim
119 words
An apparatus for molding confectionery in open molds comprising at least one open mold; a confectionery molding device for each open mold, each device including confectionEry passage means for supplying settable fluid confectionery to be sprayed in the open mold; a compressed air passage means terminating in the open mold, a spray head operatively connected to said two passage means for sealingly engaging the peripheral edge portion of the open mold, and cavity means in the spray head juxtaposed said edge portion so that the compressed air augments in forming a uniform layer of the sprayed confectionery in the open mold, the excess confectionery being removed from the open mold through said cavity means along with the compressed air.
Claim 3
Dependent Claim
102 words
An apparatus as claimed in claim 1 wherein said confectionery passage means is a central passage, one end terminating in the open mold and the other end connected to confectionery supply means; said compressed air passage means being an annular passage surrounding said central passage, one end terminating in the open mold and the other end connected to compressed air supply means; said cavity means being an annular enlarged opening in the spray head adjacent the peripheral edge of the open mold and further including a second annular passage communicating with said cavity means and a container for storing the excess confectionery.
Claim 4
Dependent Claim
31 words
An apparatus as claimed in claim 2 wherein said spray head includes a sealing ring for creating the sealing engagement and said annular enlarged opening is approximately sinusoidal in cross section.
Claim 5
Dependent Claim
37 words
An apparatus as claimed in claim 2 wherein said one end of the annular compressed air passage contains vanes positioned to cause a rotary air flow as it issues from the annular passage into the open mold.
Claim 6
Dependent Claim
24 words
An apparatus as claimed in claim 1 further including means for reciprocating the spray head into and out of engagement with the open mold.
Claim 7
Dependent Claim
51 words
An apparatus as claimed in claim 5 further including valve means for synchronizing the apparatus so that open molds are moved in a stepwise fashion into and out of operative engagement with the molding device, which in turn respectively sprays the confectionery, introduces the compressed air, and removes the excess confectionery.
