Abstract

A flexible thermoformed dispensing package for a flowable material includes an integrally formed dispensing tube extending from the container portion having an internal extension defined by one or more integral thermoformed walls extending from the bottom surface of the container and terminating proximate the base when the package is in a vertical position to facilitate sipping of a beverage from the container portion; alternatively, a straw is placed in the dispensing tube to reach the base of the package. In another embodiment, at least one integrally formed internal dividing wall extends from the sealed end of the dispensing tube and intersects an interior wall to define separate dispensing chambers, where the sealed ends of each of the dispensing chambers can be independently opened along a weakened transverse parting line and separated into separate dispensing channels along a longitudinal parting line.

Claims

1. A flexible thermoformed dispensing package for a flowable material, the package produced from one or more heat-sealable polymeric sheets and comprising:

a. a thermoformed container portion that includes a recessed chamber having opposing side walls, top and base walls and bounded by a peripheral area, the chamber configured and arranged to receive the flowable material,

b. a dispensing tube integrally formed with the container portion and bounded by a contiguous peripheral area, the dispensing tube defining a dispensing channel, the base of the dispensing tube being in fluid communication with the chamber, the package container portion and integral dispensing tube being formed from a bottom sheet,

c. an internal extension of the dispensing tube that extends into the chamber of the container portion and is formed in a portion of the bottom sheet, the internal extension being defined by at least one heat-sealable elongated region extending from the peripheral area adjacent the base of the dispensing tube, the heat-sealable elongated region including the upper surface of an interior partition wall extending to the bottom surface of the recessed chamber, the internal extension terminating in an open end positioned proximate the base wall of the container portion to facilitate withdrawal of the flowable material when the dispensing tube is in a generally vertical orientation, and

d. a top cover sheet superposed on, and heat-sealed to the periphery of the bottom sheet and to the elongated region to form a fluid-tight dispensing package.

2. The package of claim 1 in which the internal extension of the dispensing tube is contiguous to a side wall of the recessed chamber of the container portion.

3. The package of claim 1 in which an end portion of the interior wall of reduced height extends from the end of the heat-sealable elongated region to the surface of the bottom of the recessed chamber.

4. The package of claim 1 which includes a folded gusset portion formed between the cover sheet and bottom sheet and positioned opposite the peripheral position of the dispensing tube, the folded edges of the gusset being heat-sealed together and to the adjacent periphery of the bottom sheet and cover sheet to form a fluid-tight seal.

5. The package of claim 4 in which the cover sheet and gusset portion are integral with the bottom sheet and formed from a single sheet.

6. The package of claim 4 in which the gusset portion is integral with the bottom sheet.

7. The package of claim 4 where the gusset portion and cover sheet are integral.

8. The package of claim 4 in which the gusset is formed from a separate sheet.

9. A plurality of flexible thermoformed dispensing packages of claim 1 that are joined to each other along a manually separable weakened parting line to form a unitary array.

10. The unitary array of claim 9 in which the packages are joined adjacent the side wall of their respective container portions with their dispensing tube in the same position relative to the container portion.

11. The package of claim 4, in which the heat-sealable elongated region terminates above the gusset and provides fluid communication between the recessed chamber and the open end of the internal extension.
