Abstract

An edible paste dispenser for applying decorative icing to cakes and other foods includes a tip assembly that connects paste containing chambers of a dual-chamber pastry bag and directs edible paste into a common extrusion nozzle. The tip assembly includes a pair of mating tubes secured via a locking nut to the extrusion nozzle. The tubes each have a sidewall portion that is generally S-shaped in cross-section and permits stable assembly and cooperative engagement of one tube with the other tube. After insertion of a tube into each pastry bag chamber, the tubes are attached to a common extrusion nozzle. The resulting extruded paste can include two different colored decorations, which can appear swirled S or other curvilinear shape provided by the two engaged cones. The tips of the cones, and paste containing bags, terminate just above the exit portal of the common nozzle.

First claim

What is claimed is:

1. A tip assembly for an edible paste dispenser, the tip assembly comprising:
a. a dual-passageway connector formed from a first tube and a second tube, each of the first tube and the second tube having
i. a base end,
ii. an apex end,
iii. a sidewall that defines a passageway that opens at the base end and the apex end, and
iv. a thread segment formed on an outer surface of the sidewall adjacent the apex end, the sidewall of the first tube having a first curvilinear portion, the sidewall of the second tube having a second curvilinear portion, the first curvilinear portion being shaped and dimensioned to be complementary with the second curvilinear portion, wherein when the first tube is assembled with the second tube to form the connector, the first curvilinear portion forms a mating, nested engagement with the second curvilinear portion, and the thread segment of the first tube cooperates with thread segment of the second tube to form a continuous, helical, external thread about the connector, wherein the first curvilinear portion extends from the base end to the apex end of the first tube, wherein the second curvilinear portion extends from the base end to the apex end of the second tube;

b. a locking nut including an internal thread configured to engage the external thread; and
c. a nozzle secured to the connector via the locking nut, the nozzle configured to receive the apex ends such that the apex ends of the first and second tubes extend into a portion of the nozzle, wherein the nozzle is in fluid communication with the inner chamber of each of the first tube and the second tube.

2. The tip assembly of claim 1 , wherein a cross-section of the first curvilinear portion forms a non-circular convex curve and a cross-section of the second curvilinear portion forms a non-circular concave curve that is complementary to the convex curve.

3. The tip assembly of claim 1 , wherein a cross section of the first tube and a cross-section of the second tube each have a tear-drop shape.

4. The tip assembly of claim 1 , wherein
the sidewall of the first tube includes a curved first outer sidewall, and a curved first inner sidewall that defines the first curvilinear portion and cooperates with the first outer sidewall to define a first paste delivery passageway,
the sidewall of the second tube includes a curved second outer sidewall, and a curved second inner sidewall that defines the second curvilinear portion and cooperates with the second outer sidewall to define a second paste delivery passageway, and
when seen in an end view, the first inner sidewall and the second inner sidewall have complementary, generally S-shaped curves.

5. The tip assembly of claim 4 , wherein
the first outer sidewall and the second outer sidewall each have the shape of a convex circular curve, wherein when the first tube is assembled with the second tube, a resulting assembly has a circular cross-sectional shape.

6. The tip assembly of claim 4 , wherein
the first outer sidewall and the first inner sidewall each have opposed axially-extending edges that co-terminate to form first tube side edges,
the second outer sidewall and the second inner sidewall each have opposed axially-extending edges that co-terminate to form second tube side edges, and
when the first tube is assembled with the second tube, respective first tube side edges align with corresponding second tube side edges to form side interfaces that lie at an angle relative to a longitudinal axis of the connector.

7. The tip assembly of claim 1 , wherein each of the first tube and the second tube has a maximum cross-sectional dimension at the base end, and a minimum cross-sectional dimension at the apex end, and when the first tube is assembled with the second tube to form the connector, the connector is cone shaped.

8. The edible paste dispenser of claim 1 , wherein each of the first tube and the second tube has a maximum cross-sectional dimension at the base end, and a minimum cross-sectional dimension at the apex end, and when the first tube is assembled with the second tube to form the connector, the connector is cone shaped.

9. The tip assembly of claim 1 , wherein the apex ends of the first and second tubes extend into the nozzle more than half the axial length of the nozzle.

10. The tip assembly of claim 1 , wherein the apex ends of the first and second tubes extend to within 6 mm of an extrusion orifice of the nozzle.

11. A tip assembly for an edible paste dispenser, the tip assembly comprising:
a. a dual-passageway connector formed from a first tube and a second tube, each of the first tube and the second tube having
i. a base end,
ii. an apex end,
iii. a sidewall that defines a passageway that opens at the base end and the apex end, and
iv. a thread segment formed on an outer surface of the sidewall adjacent the apex end, the sidewall of the first tube having a first curvilinear portion, the sidewall of the second tube having a second curvilinear portion, the first curvilinear portion being shaped and dimensioned to be complementary with the second curvilinear portion,
wherein a cross-section of the first curvilinear portion forms a non-circular convex curve and a cross-section of the second curvilinear portion forms a non-circular concave curve that is complementary to the convex curve, and
wherein when the first tube is assembled with the second tube to form the connector, the first curvilinear portion forms a mating, nested engagement with the second curvilinear portion, and the thread segment of the first tube cooperates with thread segment of the second tube to form a continuous, helical, external thread about the connector;

b. a locking nut including an internal thread configured to engage the external thread; and
c. a nozzle secured to the connector via the locking nut, the nozzle configured to receive the apex ends, wherein the nozzle is in fluid communication with the inner chamber of each of the first tube and the second tube,
wherein a cross section of the first curvilinear portion and a cross-section of the second curvilinear portion are each generally S shaped, wherein the first curvilinear portion extends from the base end to the apex end of the first tube, wherein the second curvilinear portion extends from the base end to the apex end of the second tube.

12. An edible paste dispenser comprising a tip assembly, the tip assembly including:
a. a dual-passageway connector formed from a first tube and a second tube, each of the first tube and the second tube having
i. a base end,
ii. an apex end,
iii. a sidewall that defines a passageway that opens at the base end and the apex end, and
iv. a thread segment formed on an outer surface of the sidewall adjacent the apex end,

the sidewall of the first tube having a first curvilinear portion, the sidewall of the second tube having a second curvilinear portion, the first curvilinear portion being shaped and dimensioned to be complementary with the second curvilinear portion, wherein when the first tube is assembled with the second tube to form the connector, the first curvilinear portion forms a mating nested engagement with the second curvilinear portion, and the thread segment of the first tube cooperates with thread segment of the second tube to form a continuous, helical, external thread about the connector, wherein the first curvilinear portion extends from the base end to the apex end of the first tube, wherein the second curvilinear portion extends from the base end to the apex end of the second tube;
b. a locking nut including an internal thread configured to engage the external thread; and
c. a nozzle secured to the connecto
