## Abstract

This application is a continuation-in-part of prior U.S. application Ser. No. 711,364, filed Mar. 13, 1985 now U.S. Pat. No. 4,667,853, by Manfred Kruger, assigned to the same assignees as the present invention.

## Background
The present invention relates to a disposable syrup package for use in a post-mix beverage dispenser which is designed to substantially preclude refilling and reuse of the package.

A disposable syrup package with a break-away proportioning insert in the discharge spout thereof is disclosed in parent application Ser. No. 711,364, filed Mar. 13, 1985 to Kruger and now U.S. Pat. No. 4,667,853. As described in that application, it is desirable to provide a package which cannot be refilled with syrup and reused, in order to assure that a good quality beverage is dispensed by the dosing and dispensing equipment designed for operation with the package. In the Kruger package the reuse of the package is substantially precluded by a breakaway proportioning insert in the discharge spout, a portion of which falls into the empty container body when the dosing assembly is removed therefrom. Also in the Kruger package, the container has a rigid plastic body which is blow-molded from plastic. Because of the rigidity of the container, it may be readily fulfilled, although reuse with a compatible dosing assembly is substantially precluded by the break-away proportioning insert. However, it would be desirable to make even the refilling of the container more difficult to thwart any attempts of re-use, even if unsuccessful. Furthermore, it would be desirable to manufacture the containers at a lower cost in view of the disposable nature thereof.

Accordingly, it is a primary object of the present invention to provide a disposable syrup package, which is not only difficult to reuse, but which is also difficult to refill, making it unlikely that one would attempt to reuse the package in an improper manner with improper ingredients therein.

It is a further object of the present invention to provide a lower-cost, disposable syrup package for use in a post-mix beverage dispensing apparatus.

The objects of the present invention are fulfilled by providing a disposable syrup package for use in a post-mix beverage dispenser apparatus comprising: a collapsible bag forming a main container body having a discharge opening therein; a discharge spout secured to said discharge opening; and dosing means within said spout operatively associated with a dosing valve assembly for dispensing metered quantities of syrup through the valve assembly, the quantities of the syrup to be dispensed by the dosing means being pre-selected according to the type of syrup to be contained in the collapsible bag, said dosing means having a break-away portion which falls into said collapsible bag when a dosing valve assembly, which has been connected to said spout, is disconnected therefrom.

The objects of the present invention and the attendant advantages thereof will become more readily apparent by reference to the drawings wherein:

FIG. 1 is a perspective view illustrating a plurality of disposable syrup packages of the present invention operatively disposed in a post-mix beverage dispenser apparatus;

FIG. 2 is a side perspective view of a disposable syrup package of the present invention separated from the dispenser apparatus;

FIG. 3 is a bottom perspective view of the syrup package of FIG. 2, illustrating the proportioning insert in the spout thereof; and

FIG. 4 is a side perspective view of the package of FIG. 2 with a portion of the spout broken away to illustrate the proportioning insert.

Referring to FIG. 1, there is generally illustrated a post-mix beverage dispenser apparatus 50 including a cabinet 52 with a plurality of disposable syrup packages with collapsible bags 1 disposed therein. The dispenser apparatus and cabinet 50 are preferably of the type disclosed in U.S. Pat. No. 4,496,080, issued Jan. 29, 1985 to Farber, et al., with the addition of dividers 58 in the syrup supply compartment to help support the collapsible bags.

The collapsible bags 1 each have a removable dosing valve assembly 10 attached thereto in a manner referred to in more detail with reference to FIGS. 3 and 4. The syrup packages and dosing valve assemblies are operatively disposed in a syrup supply compartment 60 above a mixing trough 53 which is also connected to a source of carbonated water. Syrup from a selected one of the packages is mixed in metered quantities with carbonated water in trough 53, forming a post-mix beverage which is dispensed through a nozzle 54 to a cup disposed at a serving station 56.

Referring to FIGS. 2 to 4, there is illustrated the disposable syrup package of the present invention including a collapsible bag 1 formed from sheet stock of plastic material, such as polyethylene, with the edges 1A heat sealed together. A discharge spout 2 of a rigid plastic material is secured to a bag opening in a suitable fashion. The spout 2 has threads 2A thereon for engagement with threads on the female socket 10A of a valve dosing assembly 10. Spout 2 also has a proportioning insert secured therein including proportioning dome 35 with fluid passages 36 therethrough and frangible portions 38 normally connecting a top portion T and bottom portion B of the proportioning insert together.

The details of the proportioning insert and dosing valve assembly are more fully described in U.S. patent application Ser. No. 711,364, filed Mar. 13, 1985, now U.S. Pat. No. 4,667,853 the disclosure of which is incorporated herein by reference.

In operation, a disposable syrup package for a selected beverage is selected from a storage location. A dosing valve assembly 10 is screwed into spout 10. When assembly 10 is fully tightened, frangible areas 38 fracture, separating top and bottom sections T and B. The package is then loaded into the dispenser 50 of FIG. 1. When the package becomes empty, it is removed from the cabinet and assembly 10 is unscrewed therefrom. Top T of the proportioning insert, including dome 35 is then free to fall into collapsible bag 1, or it at least becomes non-functional. Futhermore, the empty bag 1 tends to stick together in a wad, making refilling extremely difficult.

The bags 1 and associated spouts 2 could be shipped in multi-paks of a variety of flavors. To use, a selected flavor would be removed from the box and placed into dispenser 50 after attaching a selected dosing assembly 10.

The bags 1 are preferably polyethylene, but could also be multi-layered structures designed to provide oxygen or water barriers.

It should be understood that the package of the present invention could be further modified as would occur to one of ordinary skill in the art without departing from the spirit and scope of the present invention.
