Description

FIELD OF THE INVENTION

The present disclosure relates to a dispenser for semi-solid foods, such as a pastry bag.

BACKGROUND OF INVENTION

There have been many devices conceived to ease the making and to allow creative design of semi-solid foods, such as pastries. A common example of such device is a pastry bag, which eases the disposal of fluid on meals, for example icing on cakes. Typical pastry bags are made of a disposable plastic bag comprising an aperture at one of its corner. The user fills the disposable plastic bag with the food product to be dispensed, then applies pressure to press out the food preparation from the aperture of the plastic bag, and after use throws away the plastic bag and the remains of the food product.

SUMMARY OF THE INVENTION

According to one aspect, this disclosure relates to a food dispensing device comprising a bag for receiving a semi-solid food preparation; a connector permanently secured to the bag; and a dispensing tip releasably mounted to the connector. The bag has a wide opening at one end and a narrow opposite opening that is permanently secured to the connector. The wide opening is used to fill the bag with the food preparation, which is expressed through the connector to which the dispensing tip is mounted. Preferably, the connector and the bag are co-molded. They are made of plastic materials that are permanently jointed to each other to form a unitary structure. Different tips can thus be interchangeably used to dispense the food preparation in different shapes.

The dispensing tip can be mounted to the connector in different ways. One option is to use a bayonet connection. Another option is to use a threaded (screw-on) connection.

The threaded connection can be adapted to accept dispensing tips used with prior art pastry bags.
