Field of the Invention a This invention relates to a packaging system for retaining an article with a cored product. More specifically, this invention relates to a packaging system in which an article, such as a give-away premium, is packaged with a cored, rolled, web product, such as towels, napkins, facial tissue, toilet tissue, plastic wrap, waxed paper, aluminum foil and the like.

The term cored, as used throughout the specification and claims to describe products of this invention refers to products having an opening extending inwardly from at least one exposed surface thereof, and in which the opening is defined by a separate core member, or by the products themselves.

2. Description of the Prior Art It is often desirable to package an article, such as a rial. If the premium is packaged loosely within the opening of the cored product, it can constantly shift position during handling. This shifting of position can cause damage to the premium. Additionally, when an overwrap material is employed, the shifting of the premium can cause damage to the overwrap material. If the premium is packaged in tight frictional engagement with the walls defining the opening of the cored product to prevent shifting of said premium, said premium is difficult to remove by a purchaser.

When a substantially flat premium, such as a wash cloth or handkerchief, is packaged with a cored product, it has been suggested to hold the premium to a size commensurate with that of the cored product, and to position the premium adjacent the front or rear surface of said product. Several problems exist with this type of packaging system. First, this arrangement of packaging premiums increases the overall size of the packaging system and is somewhat unattractive. When the size of the packaging system is increased less packages can be placed on a given shelf space and in shipping cartons. This is a significant merchandising problem. Second, it is difficult to handle substantially flat premiums in a reliable manner to insure that they are maintained flat against the cored product as an overwrap material is secured about the product. Third, the premium can be pilfered easily by merely providing a slit in the overwrap material and pulling the premium through the slit.

SUMMARY OF THE INVENTION The packaging system of this invention includes a cored product and an article-containing package. The article-containing package includes an articlecontaining compartment disposed within the opening of the cored product, and a peripheral rim providing a supporting surface in overlying relationship, and in contact with the outer surface of the cored product through which the opening extends. In the preferred embodiment of this invention, a flexible overwrap material is tightly secured about one or more cored products with the article-containing package assembled with at least one of the cored products. This overwrap material firmly retains the peripheral rim of the articlecontaining package between itself and the outer surface of the cored product. In this manner the articlecontaining package is maintained in its proper assembled position, i.e., it will not slip completely within the interior of the core or otherwise shift relative to the cored product during handling.

The packaging system of this invention is more pilfer proof than packaging systems in which the premium is packaged adjacent the front or rear surface of the cored product. In order to pilfer the premium in the packaging system of this invention, a substantially large area of the overwrap material must be torn in order to permit the peripheral rim of the article-containing package to clear the overwrap material.

In the preferred embodiment of this invention, the peripheral rim extends entirely about the outer periphery of the article-containing package to substantially uniformly distribute the weight of the package, with the article contained therein, over the outer surface of the cored product to further prevent the package from sliding completely within the interior of the core. Therefore, a purchaser of the packaging system can easily remove the article-containing package from the cored product by engaging the peripheral rim which is disposed against the outer surface of said cored product.

In the preferred embodiment of this invention, the

maximum transverse dimension of the article-receiving compartment is less than the minimum transverse dimension of the opening of the cored product to permit easy insertion of the compartment within said opening. The article-containing packages of this invention are of a fixed dimension. Therefore, mass production equipment can be utilized in an effective manner for reliably assembling the article-containing package with the cored product.

In the preferred embodiment of this invention both the article-containing package and the flexible overwrap material are formed of a transparent plastic material. In this manner a prospective purchaser can view the premium without opening the package system.

It is an object of this invention to provide a simple, inexpensive packaging system in which an article, such as a give-away premium, is included with a cored product.

It is a further object of this invention to provide a packaging system in which an article is included with a cored product, and can be easily removed from the cored product.

It is a further object of this invention to provide a packaging system in which an article is included with a cored product without substantially increasing the overall dimension of the packaging system.

It is a further object of this invention to provide a packaging system in which an article is included with a cored product, and in which the article can be viewed through the packaging system without opening the packaging system.

Other objects and advantages of this invention will become apparent in view of the detailed description which follows, taken in conjunction with the drawings.

FIG. 2 is an exploded isometric view of the articlecontaining package by itself;

FIG. 3 is an isometric view of a packaging system according to this invention which includes a flexible overwrap material; and

FIG. 4 is a sectional view taken along line 44 of FIG. 3, and viewed in the direction of the arrows.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION Referring to FIG. 1, a packaging system according to this invention includes an article-containing package and a cored product 12. The cored product 12 has a central opening 14 extending through outer surfaces 16 thereof. The opening 14 can be defined by inner walls of a core member 18 or by the product alone. In the preferred embodiment of this invention, the cored product 12 is a web material disposed in roll form.

Referring to FIGS. 1 and 4, the article-containing package 10 is in the form ofa blister pack, and includes a closed, article-containing chamber 20 terminating at a distal end 22 disposed out of the general plane of a peripheral rim 24. The article-containing chamber need not be closed, but could be in the form of a sling comprising separate spaced wall members secured together at their distal ends. This sling arrangement is well suited for packaging elongate articles, such as candles and the like, within an opening of a cored product. The peripheral rim 24 has an inner exposed surface 26 which engages one of the outer surfaces 16 of the cored product 12 when the article-containing package 10 is assembled with the cored product. In the preferred embodiment of this invention the article-containing chamber 20 has a maximum transverse dimension which is slightly less than the transverse dimension of the opening 14 within the core member 18 to permit easy insertion of the article-containing chamber 20 within the opening 14 (FIG. 4).

Referring to FIG. 3, it is conventional to package together more than one core product with a flexible overwrap material 28. FIG. 3 shows two cored products 12 wrapped tightly by a flexible overwrap material 28 which can be paper, plastic, or the like. It is within the scope of this invention to utilize an overwrap material to package one or more cored products as a unit, and the two-roll.arrangement shown in FIG. 3 is intended as exemplary only. An article-containing package 10 can be included with one or more of the cored products 12, and in FIG. 3 the article-containing package 10 is shown as being included with only one of the cored products.

Referring to FIGS. 3 and 4, the flexible overwrap material 28 is wrapped tightly about the cored products 12 to firmly retain the peripheral rim 24 of the articlecontaining package 10 between the overwrap material and the outer exposed surface 16 of the cored product. In this manner, the article-containing package 10 is prevented from shifting out of its proper assembled position with the cored product 14 during handling and storage.

Referring to FIG. 2, the article-containing package 10 is formed of an article-receiving section 30 and a closure section 32. This article-receiving section 30 has an article-receiving cavity 34 therein formed by any conventional method, such as thermoforming. The peripheral rim 24 extends about the periphery of the cavity 34, and defines an opening into said cavity 34 through which an article 36, such as a give-away premium, can be inserted. The article 36 can be any desired item which fits within the confines of the cavity 34. The closure section 32 is disposed over the opening into the cavity 34 after the article 36 has been inserted therein, and the closure section is secured to the article-receiving section by any suitable means.

In the preferred embodiment of this invention both the article-containing package 10 and the flexible overwrap material 28 are formed of a transparent material to permit a prospective purchaser to view the article 36 without opening the packaging system. The preferred materials for the article-containing package 10 are transparent thermoplastics, such as polyethylene, polypropylene, vinyl and polyvinyl chloride. The preferred materials for the overwrap material 28 are transparent, flexible thermoplastics, such as polyethylene and polypropylene. When the article-containing package 10 is formed of a thermoplastic material, the articlereceiving section:30 is adhered to the cover section 32 by spaced heat seals 38, although other sealing means such as glue, adhesive and the like can be utilized.
