A decorating pen particularly useful for decorating cakes, pastries and other food items provides a reservoir containing a decorating material, a nozzle attached to the reservoir, a housing which holds the reservoir and a compression member pivotally attached to the housing member. A user holds the decorating pen in a fashion similar to a standard writing pen or pencil and squeezes the housing and compression member together to extrude the decorating material from the reservoir through the nozzle to write, draw, or color with the decorating pen.

1. A decorating tool comprising a compressible reservoir having a proximal end, a distal end and a wall extending from the proximal end to the distal end, the reservoir containing a decorating material; a nozzle coupled to the distal end of the reservoir through which decorating material exits the reservoir; a housing having a proximal end having a hinge member, a distal end having a flange adjacent a distal opening, a channel defined by a wall having a side opening, and a slot extending through the wall inwardly from the proximal end of the housing for receiving the proximal end of the reservoir; and a compression member pivotally coupled to the hinge member of the housing so that the compression member is movable with respect to the housing between a first position in which the side opening is exposed to permit the reservoir and nozzle coupled to the reservoir to be placed through the side opening and into the channel with a portion of the nozzle projecting through the distal opening and past the distal end of the housing and a second position in which at least a portion of the compression member resides within the channel of the housing, wherein as the compression member is moved from the first position to the second position the compression member engages the compressible reservoir so that the reservoir is squeezed between the housing wall and the compression member to force material within the reservoir out the nozzle. 2. The decorating tool of claim 1 wherein the compression member progressively engages the wall of the reservoir from the proximal end of the wall toward the distal end of the wall to move material within the reservoir toward and out the nozzle. 3. The decorating tool of claim 1 wherein the slot is curved. 4. The decorating tool of claim 1 wherein the housing wall and the side opening are tapered. 5. The decorating tool of claim 4 wherein the compression member is tapered in a manner corresponding to the tapered wall and side opening of the housing to permit a portion of the compressible member to pass through the side opening. 6. The decorating tool of claim 1 wherein the compression member has a recess to assist in positioning a finger of a user. 7. The decorating tool of claim 1 wherein the hinge member includes a pair of slots in the housing which engage a pair of pins projecting from the compression member. 8. The decorating tool of claim 1 wherein the reservoir is a collapsible bag. 9. The decorating tool of claim 8 wherein the bag is made of a material selected from paper, cloth or plastic. 10. The decorating tool of claim 1 wherein the decorating material is edible. 11. The decorating tool of claim 1 wherein the decorating material is selected from frosting, icing or ice cream. 12. The decorating tool of claim 1 wherein the housing and the compression member are made from a plastic material. 13. The decorating tool of claim 1 wherein the nozzle has exterior threads and further including a nut having internal threads used to join the nozzle to the reservoir. 14. The decorating tool of claim 1 wherein the nozzle includes a selectable nozzle orifice. 15. A decorating kit comprising: a. at least one compressible reservoir for containing a decorating material, the reservoir having a proximal end, a distal end and a wall extending from the proximal end to the distal end;b. a plurality of nozzle orifices providing differing nozzle openings;c. a nozzle body used to couple a selected one of the nozzle orifices to the distal end of the reservoir such that decorating material can exit the reservoir through the nozzle opening of the selected nozzle orificed. a housing having a proximal end having a hinge member, a distal end having a flange adjacent a nozzle receiving opening, a wall defining a channel and a side opening to the channel, and a slot extending through the wall inwardly from the proximal end of the housing for receiving the proximal end of the reservoir; ande. a compression member pivotally coupled to the hinge member of the housing so that the compression member is movable with respect to the housing between a first position in which the side opening to the channel is exposed to permit the reservoir and nozzle coupled to the reservoir to be placed in the channel such that a portion of the selected nozzle orifice projects through the nozzle receiving opening of the housing and past the distal end of the housing and a second position in which at least a portion of the compression member resides within the channel of the housing, wherein as the compression member is moved from the first position to the second position the compression member engages the compressible reservoir so that the reservoir is squeezed between the wall of the housing and the compression member to force material within the reservoir out the nozzle opening of the selected one of the orifices. 16. The decorating kit of claim 15 further comprising at least one additional compressible reservoir. 17. The decorating kit of claim 16 wherein each compressible reservoir may contain a different decorative material. 18. The decorating kit of claim 16 further comprising at least one additional nozzle body.
