Dispensing Bag with Longitudinal Split

Abstract

An improved dispenser bag, suitable for use as a pastry bag or mortar bag is disclosed. The bag is a flexible and conical-shaped with a first end opening formed by truncation of the bag near the apex of the cone and a second opening at the opposite end. In embodiments the surface of the bag is split a distance longitudinally from the second opening for a distance and can be releasable opened and closed with a fastener. The lateral opening allows easy access to the interior region of the bag for filing and the removal or insertion of a tubular tip. An extended flap member is attached to the inside surface of the bag and is formed to extend inside of, and across, the split, so as to minimize loss of material through the split.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention is directed to a dispenser device such as pastry bag or mortar bag, used to apply viscous liquids such as icing or mortar, and, more particularly, a flexible frusto-conical shaped bag that has a re-sealable extended split or opening extending from the large circular opening along its sidewalls toward a smaller opening. The split facilitates filling of the bag.[0003]2. Description of the Prior Art[0004]Flexible bags have been sued to dispense viscous fluids for many years. For example, decorative icings long have been applied to cakes and other pastries through use of pastry bags. These bags are generally formed in the shape of a cone and constructed of a flexible fabric such as canvass, synthetic resin, or other waterproof or water-resistant cloth. The bags are filled with icing, and as pressure is imposed on the bag, icing is forced out of a hollow nozzle at the top of the cone and through a tubular tip ...

AI Technical Summary

Benefits of technology

[0013]The present invention provides a variable dispenser bag, suitable for use to dispense viscous liquids, which meets the aforementioned needs. The bag may be advantageously used as a pastry bag, a mortar bag or to apply caulk, sealant or putty. A flexible, conical-shaped bag is provided with a first small circular end opening formed by truncation of the bag near the apex of a cone formed by the bag and adapted to receive a tip, and a second larger circular opening at the opposite end at the bottom of the come. In a first embodiment, the sidewall surface of the bag is split a distance

Problems solved by technology

While the use of these bags remains popular, filling the bags with icing or mortar is often difficult because the flexible sidewall will not remain open position to allow easy access to interior of the bag.

Since the materials that are dispensed from the bags are dense and viscous, it is sometimes difficult to fill the bags without having filler material adhere to the bag at or near the near the edge of the opening.

Notwithstanding these solutions, the viscous material nevertheless frequently comes into contact with the top edges of the bags and consequently with the
