Abstract

A package is defined to retain a first product and a separate ingredient. The package includes a hollow tubular body and first and second end closures sealed to the ends of the tube. A retainer cup is provided for storing the separate ingredient. The retainer cup includes a generally tubular cup wall, with an upper edge portion defining a support rim that surrounds a cup opening. One sidewall of the cup wall includes a plurality of concave curved groves forming a scalloped surface. The scalloped surface extends longitudinally along the cup wall and defines a scalloped edge profile for the support rim. A closure lid overlies the cup opening and closes the separate ingredient within the cup interior.

First claim

What is claimed is:

1. A package for retaining a dough product and a separate ingredient, the package comprising:
a tubular body for retaining a dough product, the tubular body having a generally cylindrical sidewall, a hollow interior and first and second open ends;
first and second end closures respectively secured to the first and second open ends of the tubular body;
a retainer cup for storing the separate ingredient, the retainer cup having a bottom wall, a generally tubular cup wall extending from the bottom wall, and an upper support rim at a top end of the cup wall, the cup wall having an upper edge portion defined by the support rim, the support rim surrounding a cup opening, the cup opening providing access to a cup interior and the separate ingredient, and the bottom wall closing a bottom end of the cup wall;
an outside sidewall of the cup wall having a plurality of concave curved grooves forming a scalloped surface, the grooves projecting inwardly into the cup wall and reducing the effective thickness of the cup wall, the scalloped surface extending along the cup wall from the bottom wall to the upper edge; and
a closure lid engaging the upper edge of the support rim on the retainer cup, and overlying the cup opening, the closure lid closing the separate ingredient within the cup interior,
the closure lid coaxially positioned with the retainer cup within the tubular body adjacent the first open end, and
the scalloped surface of the outside sidewall of the cup wall positioned adjacent an inside surface of the cylindrical sidewall of the tubular body,
wherein the concave grooves of the scalloped surface form spacing relative to the inside surface of the tubular body along the cup wall, and
wherein the closure lid positioned on the upper edge of the support rim is structurally supported by the cup wall when the retainer cup is positioned within the tubular body and adjacent the first closure.

2. The package of claim 1 wherein the cup wall further comprises a plurality of longitudinally extending ribs, with each of the ribs from the plurality positioned on the outside sidewall between adjacent concave grooves of the scalloped surface.

3. The package of claim 1 wherein the scalloped surface of the cup wall further defines a scalloped profile on the upper edge portion of the support rim.

4. The package of claim 1 wherein the closure lid further comprises a generally planar center portion and a rounded outer periphery.

5. The package of claim 1 wherein the closure lid snap-fits onto the support rim of the cup.

6. The package of claim 1 wherein a first portion of the cup wall has a first outside diameter and an upper portion of the cup wall flares outwardly from the first outside diameter, wherein the upper portion adjacent the upper edge portion is positioned radially outward of the outside diameter of the first portion.

7. The package of claim 1 wherein the scalloped surface is formed on the upper edge portion adjacent the support rim.

8. A package for retaining an expandable first product and a separate ingredient, the package comprising:
an elongated tubular body for retaining an expandable first product in a first portion thereof, the tubular body having a generally cylindrical sidewall, a hollow interior and first and second open ends;
first and second end closures sealingly closing the first and second open ends, respectively, of the tubular body;
a retainer cup for storing a separate ingredient in a second portion of the tubular body adjacent to the expandable first product, the first and second portions of the tubular body being axially arranged within the hollow interior, the retainer cup having a bottom wall and a generally tubular cup wall projecting from the bottom wall, the cup wall having an upper edge defining a support rim, the support rim surrounding a cup opening, the cup opening providing access to a cup interior volume and the separate ingredient retained therein, and the bottom wall closing a bottom end of the cup interior volume, the retainer cup retained within the tubular body adjacent the first closure secured to the first end; and
an outside sidewall of the cup wall having a plurality of adjacently positioned longitudinally extending, inwardly directed concave curved grooves forming a scalloped surface within an outside surface of the cup wall, the scalloped surface of the cup wall extending from the bottom wall to the upper edge, the scalloped surface further defining a scalloped edge profile adjacent the support rim; and
a closure lid configured to engage the support rim on the retainer cup, to be supported by the cup wall and to overlie the cup opening, the closure lid closing the separate ingredient within the cup interior volume;
the retainer cup and the closure lid stacked within the tubular body, with the closure lid separating the expandable first product from the separate ingredient within the cup interior volume, and the bottom wall contacting the first end closure and the cup wall extending axially within the tubular body, the scalloped surface of the cup wall closely adjacent an interior surface of the cylindrical sidewall of the tubular body and the longitudinal concave grooves of the scalloped surface spaced from the interior surface of the tubular body,
wherein pressure from the expandable first product is exerted on the closure lid and is transmitted through engagement of the support rim to the cup wall and in turn to the first end closure, and wherein the cup wall supports the closure lid within the package, and wherein the concave grooves of the scalloped surface remain spaced from the interior of the tubular wall forming a passageway therebetween.

9. The package of claim 8 wherein the cup wall further comprises a plurality of longitudinally extending ribs, with each of the ribs positioned between adjacent concave grooves on the outside surface of the side wall.

10. The package of claim 8 , wherein the closure lid further comprises a generally planar center portion and a rounded outer periphery.

11. The package of claim 8 wherein a first portion of the cup wall comprises a first outside diameter and the upper portion of the cup wall flares radially outwardly from the first outside diameter to form a second outside diameter, wherein an outside surface of the upper portion, adjacent the upper edge portion, is positioned radially outward of an outside surface of the first portion of the cup wall.

12. The package of claim 8 wherein the closure lid snap-fits onto the support rim of the cup.

13. A package for retaining an expandable first product and a separate ingredient, the package in combination comprising:
a tubular body for retaining an expandable first product in a first portion thereof, the tubular body having a generally cylindrical sidewall, a hollow interior and first and second open ends;
first and second end closures sealingly closing the first and second open ends, respectively, of the tubular body;
a retainer cup for storing an separate ingredient in a second portion of the tubular body adjacent to the expandable first product, the first and second portions of the tubular body being axially arranged within the hollow interior, the retainer cup having a generally tubular cup wall, the cup wall having an upper edge defining a support rim, the support rim surrounding a cup opening, the cup opening providing access to a cup interior, the separate ingredient retained within the cup interior, and a bottom wall closing a bottom end of the cup interior, the retainer cup retained within the tubular body adjacent the first closure secured to the first end of the tubular body, and
a plurality o
