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

The present invention is a flexible bag designed for dispensing viscous liquids like cutters, caulk, and sealants. It has a conical shape with two circular openings. The size of the opening can be adjusted by a zipper or flap. The bag is made to minimize material loss and has reinforced edges to prevent rupture. The technical effects of this invention are its flexibility, adjustable size, and durability.

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 user.

Material on the top edges of the bags is undesirable as it comes into contact with the user and generally becomes a mess.

The repeated filling of the bag tends to exacerbate this problem.

It is often difficult to place a viscous material within the bag though the top opening.

However, the use of numerous tubular elements and couplers requires additional cleaning, the parts can become lost, and the pressure required on the bag to force the material through the tip is increased.

In addition, these solutions do not address the problems associated with filling the bags.
