Abstract
A bag for a frozen dessert dispenser includes a spout which has a tab which projects down into the bag to ensure that the bag does not cover the outlet opening. The spout also includes an indentation which mates with a projection on the dispenser to ensure that the tab is properly oriented in the dispenser.
Description
NOZZLE FOR FROZEN DESSERT BAG
BACKGROUND OF THE INVENTION
Frozen dessert dispensers (ice creams) that use flexible bags to contain the frozen dessert are known, as shown in United States of America Patent # 5,421, 484"Beach". These dispensers provide an efficient and sanitary way to contain and dispense frozen desserts. However, certain problems still exist with these dispensers.
In a dispenser like the one taught by the "Beach" patent, the frozen dessert is pressed out of the mouthpiece by pushing against the bag with a piston. When the dispenser finishes dispensing, the piston is released and can fall down. Also, when the door is opened to change an empty bag, the pistons are released for all the bags, which again can allow all the pistons to fall. Whenever the piston moves down, the frozen dessert inside the bag can also fall to the bottom of the bag, leaving a hole in the top of the bag. When the piston again pushes against the bottom of the bag to squeeze out more frozen dessert, the empty top portion of the bag can be deformed. In many cases the upper empty portion is deformed so that it partially or completely covers the opening of the bag through which the frozen dessert must pass. Then, while the piston pushes against the bottom of the bag, the dessert can not be pressed out through the opening, and the dispenser does not work.
SUMMARY OF THE INVENTION
The purpose of the present invention is to solve the problem described above. The present invention provides a flap in the nozzle of the flexible bag, which projects down the nozzle, preventing the flexible bag from deforming, and thus preventing the bag from closing the opening.
The present invention also provides a slit or depression in the nozzle, and a coupling projection in the dispenser which ensures that the fin is correctly oriented in the dispenser when the bag is installed in the dispenser.

DESCRIPTION OF THE PREFERRED INCORPORATION
Figure 1 is a side sectional view showing an example of a dispenser 10, made according to the present invention. The dispenser 10, includes a body 12, which is made of two pieces 14, 16, which are clamped together to form an interior 18 and an exterior 20. There is a piston 22, either in or on the body, for pressing ar pos re conge aoua del dispensador. At the upper end of the body 12 there is a passage 24 going from the interior 18 to the exterior 20 through which frozen dessert passes out of the dispenser 10. In this embodiment, the aisle 24 includes a horizontal portion 26 and a vertical portion 28. A valve member 30 slides up and down the vertical portion 28 to open and close the passage 24. The valve member 30 is operated by a crank 32, which rotates about a pivot point 34, formed of a pin passing through a hole in the handle 32 and which is fixed to the machine.
As is well known in the art, the entire apparatus shown in Figure 1 is preferably located within a refrigerated cabinet, except crank 32 and the outer opening of the aisle 24. This becomes clear by showing the top of the ghost cabinet in Figure 1. As is also well known in art, the manual movement of the crank 32 up and down not only controls the valve member 30 to open and close the passage 24, but also controls the movement of the piston 22 so that the piston 22 is pushing upward, squeezing product towards outside the dispenser 10 when the crank 32 is pushed down, opening the aisle 24, and the piston 22 is released and allowed to fall again when the crank 32 is turned upward, closing the aisle 24.
The piston 22 is preferably operated using air pressure to push the piston up and then releasing the air pressure when it is not desired to dispense frozen dessert.
Inside the interior 18 of the body 12 there is a flexible plastic bag 36, which is impermeable to water. The pouch 36 has a cylindrical shape, which corresponds to the cylindrical shape of the interior 18. Near the top of the pouch 36, on the side wall of the pouch 36 there is an opening 38. A one, only shape that the dessert frozen can leave the bag 36 is through the nozzle 40. The nozzle 40 has an external diameter corresponding to the internal diameter of the horizontal portion 26 of the passage 24, so that, when the upper and lower parts 14, 16 of the body 12 are put together, nozzle 40 is received in aisle 26 and fits fully.
The nozzle 40 is cylindrical, and has an axis 42. The nozzle 40 also has two annular projections 44 on its outer surface which are received in annular grooves 46 in the passage 24 to axially properly locate the nozzle in the passageway 24.
Figures 3 and 4 show the nozzle 40 in greater detail. The nozzle 40 has a flange 48 at its first end, which provides a surface on which the bag 36 is welded. There is also an elongate fin 50 projecting downward from the flange 48. In this preferred embodiment, the fin 50 extends downwardly from the outer surface of the nozzle 40, substantially perpendicular to the axis of the nozzle 40, a distance that is greater than twice the external diameter of the nozzle. It is to be expected that the flap 50 should extend downwardly at least the distance of an external diameter beyond the nozzle in order to prevent the bag 36 from bending over itself and thereby closing the opening 38.
Figures 3 and 4 show that the nozzle 40 has a slit 52 on its surface external to the bottom of the nozzle, at the first end of the nozzle. The slit 52 is conical so that, at the first end of the nozzle 40, it is at the outer diameter of the nozzle, and then, as it extends toward the second end of the nozzle 40, the slit 52 becomes deeper , until there is a well-marked tier at the other end of the indentation.
