Abstract

Abstract A hygienic dispenser for hard candies and medicaments in wafer form, each package of which is constituted by a stack of such wafers protectively sealed in an inner foil wrapper to create a roll that is surrounded by a removable outer sleeve. The dispenser includes a tubular container for receiving the roll through its open end and to seat it on an axially-advanceable platform which urges the roll upwardly. Covering the open end of the container and pivoted thereto is a cap whose thickness corresponds to that of a wafer. The cap is laterally swingable to a cocked position in which the open end is uncovered to release the roll which is then advanced by the platform to engage a visor projecting from the top of the cap, thereby exposing the uppermost wrapped wafer. When the cap is swung back to again cover the open end, it acts to sever the wrapper and discharge the uppermost wafer, the next wafer in the roll then engaging the cap in readiness for the next operation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 242 words
A hygienic dispenser for edible wafers having a predetermined thickness, the wafers being stacked and being sealed within a wrapper to create a roll; the dispenser comprising: A. a tubular container having an open end to receive the roll; B. a platform disposed in said container and axially advanceable therein, the roll being seated on the platform; C. means to advance said platform to push said roll toward the open end of the container; D. a cap provided at its top with a visor and having a thickness substantially matching said predetermined thickness, said cap being pivoted on said container and being laterally swingable relative to the open end thereof so that the cap may selectively assume a storage mode position in which it closes the open end of the container, a cocked mode position in which the open end is uncovered by the cap but the visor thereof overlies the open end to permit said platform to push the roll upwardly, thereby projecting the uppermost wrapped wafer above the open end of the container to engage the overlying visor, and an operating mode in which the cocked cap is swung back from its cocked mode position to its storage mode position, in the course of which movement the wrapper is severed by the cap and the uppermost wrapped wafer is discharged laterally from the dispenser; and E. stop means cooperating with said cap to limit movement thereof to said mode positions.
Claim 2
Dependent Claim 242 words
A hygienic dispenser for edible wafers having a predetermined thickness, the wafers being stacked and being sealed within a wrapper to create a roll; the dispenser comprising: A. a tubular container having an open end to receive the roll; B. a platform disposed in said container and axially advanceable therein, the roll being seated on the platform; C. means to advance said platform to push said roll toward the open end of the container; D. a cap provided at its top with a visor and having a thickness substantially matching said predetermined thickness, said cap being pivoted on said container and being laterally swingable relative to the open end thereof so that the cap may selectively assume a storage mode position in which it closes the open end of the container, a cocked mode position in which the open end is uncovered by the cap but the visor thereof overlies the open end to permit said platform to push the roll upwardly, thereby projecting the uppermost wrapped wafer above the open end of the container to engage the overlying visor, and an operating mode in which the cocked cap is swung back from its cocked mode position to its storage mode position, in the course of which movement the wrapper is severed by the cap and the uppermost wrapped wafer is discharged laterally from the dispenser; and E. stop means cooperating with said cap to limit movement thereof to said mode positions.
Claim 3
Dependent Claim 29 words
A dispenser as set forth in claim 1, wherein said wrapper is a foil inner wrapper surrounded by a removable sleeve which is withdrawn before the roll is inserted.
Claim 4
Dependent Claim 37 words
A dispenser as set forth in claim 1, wherein said means to advance said platform is constituted by a spiral spring interposed between the bottom of the container and the platform, said spring urging said platform upwardly.
Claim 5
Dependent Claim 19 words
A dispenser as set forth in claim 1, wherein said cap and container are formed of synthetic plastic material.
Claim 6
Dependent Claim 24 words
A dispenser as set forth in claim 3, wherein said container is provided with a reentrant bottom defining a socket to accommodate said spring.
