1 Claim. (Cl. 206-47) This invention relates to a package of the type wherein there is an inner liner or bag arranged within a carton. The inner liner or bag is adapted to be filled with a substance or with articles and receivable in the carton, the carton then being sealed to form a totally inclosed air tight carton.

The present invention contemplates an article adapted to be placed or arranged inside the carton and supported on an overhanging part of the liner or bag. The liner or bag is adapted to be folded over or configurated in such a manner as to hold the article in position on top of the overhanging part of the bag and exteriorly thereof but within the container.

The substance or articles in the container may be, any kind or type of articles or materials but is herein specifically defined as granular material, such as popcorn, peanuts, and the like. The material or substance is adapted to be placed inside of the liner or bag while the liner or bag is positioned within the carton but before the material is placed into the bag. The liner or bag is then filled, after which time it is sealed and folded over to a particular configuration so as to receive and support an article. The latter article may be any one of several types or kinds but is herein specifically defined as being a toy as a prize. While the invention is described specifically as being granular material such as popcorn and the like, and the article is adapted to be a prize such as a toy, it is to be understood that the liner may be filled with any substance or material, and the article may be any kind of an article which is adapted for cooperation or usage with the material or articles in the bag. The concept of the invention being of a breadth sufficient to include nuts or washers within the bag, and the article may be abolt or rod, or any other element or vice versa. The invention, however, is being herein specifically described with respect to a confection, such as popcorn or peanuts, in which a prize in the nature of a toy is arranged inside of the carton.

In some states there are laws preventing a toy or other prize from being packaged along with the edible material, such as a whistle commingled directly with the confection, because children are accidentally likely to swallow a small prize while they are eating a confection. It has heretofore been customary to have the prize inserted in a special envelope or package arranged inside of the bag along with the confection. It has also been customary that the bag or envelope be of such a size and proportion so that it cannot be swallowed along with the confection.

It is desirable, therefore, that expense be saved in providing a special package or envelope for the prize, and it has been found more economical and convenient to insert the prize separately from the material. It is desirable, too, that upon opening the package, the first thing that is available is the prize, and that the prize be located outside of the bag, separate and away from the confection, but readily available and accessible immediately upon opening the outer carton. the primary object of the present invention to provide a package comprising an outer box-like container and an inner bag or liner, wherein the liner or bag holding the substance is tightly sealed and air tight, but with the liner elongated and configurated to provide a shelflike end to support the prize at the end of the carton which is to be opened and at the end of the bag which is to be opened.

Another object of the invention is the provision of forming a package by configurating a liner to form a shelf to receive an article thereon, the liner having an open top to receive material while the liner is in the carton after which time the liner is folded and sealed and then the carton closed and sealed.

Numerous other objects and advantages will be apparent throughout the progress of the specification which follows.

The accompanying drawing illustrates a certain selected embodiment of the invention, and the views therein are as follows:

Fig. 1 is a detail perspective view of the package in open position, the package including the inner sealed liner "or. bag, the upper end of the liner being extended and configurated to provide a shelf to support an article, such as a prize in the nature of a toy;

Q end of the bag or liner of Fig. 2;

' the application of heat.

Fig. 4- is a detail longitudinal vertical sectional view showing the manner in which the closed end of the liner or bag-is configurated to support the article, the liner and article being arranged within the carton after the carton is closed and sealed; and

Fig. 5 is a detail transverse sectional view on the line panel 2', is provided with an integral extension 8, Fig 5, which is overlapped along the end 4, the same being glued along the seam 9. The top and bottom are closed by end flaps 10 including a tuck flap, and end flaps 11,

11. An inner liner or bag 12, is arranged inside of the carton 1 and receives the material, substance or articles.

The liner or bag 12 is formed from a single piece of material of the type which may be sealed together upon The particular material from which the liner or bag is made may be any heat scalable material but in actual practice the bag material is a product sold under the trade-mark Reyseal, although other materials may be used for the same purpose, just so long as the bag is airtight and dustproof and preferably heat sealable. The bag or liner 12 is formed about mandrels, the exterior surface of which is slightly less in size than the inside of the carton 1 so as to permit easy insertion. The liner bag 12 is relatively of the same configuration as that of the carton, being herein shown as rectangular in cross section and elongated longitudinally. The liner or bag 12 comprises opposed front and

rear walls

13, 13 and end walls 14, 14-. The free ends of the sheet of material from which the liner or bag is made, overlap and are sealed along the line intermediate the one side of the bag or liner as indicatedat 15, Fig. 5. The ends extending from one end to the other are adapted to be folded It is therefore,

at the top and bottom. The overlapping parts and the sealing seam part are located between the

opposed ends

14, 14, preferably half way between, as shown in Fig. 5, thereby permittinga tight seal. Heretofore, certainliners were sealed together at an edge or at a corner, thus preventing the formation of a proper tight seal and preventing proper sealing and cooling time intervals during the formation of the bag or liner. After the liner 12 has been formed and the bottom end of the liner bag 12 has had its lower end folded and sealed, as indicated at 16. Fig. 3, it is inserted into the carton 1 with its upper end open. A sufiicient or proper amount of material is then inserted, preferably automatically, into the liner, while the liner is housed within the carton 1. The upper end of the liner is then folded upon itself and heat sealed and pressed together so as to make a water and air tight seal along the folded seal in the bracketed area indicated at 1.7, Fig. 2', so that the complete upper end of the liner bag is tightly sealed. The upper sealed area, as defined by the bracket area 17, Fig. 2, is bent downwardly at an angle along the line 18, Fig. 4 to form the downwardly inclined part 19. The folded and sealed area 17 then is curved, as indicated at 20 terminating in a relatively upwardly inclined end 21' to form a trough-shaped shelf 22, Fig. 4. The folded and sealed part 17 projects from one side. of the liner 12, Fig. 4, which side is preferably the rear side 3. It then extends downwardly and forwardly from the line 18 in a relatively straight line to the curved part 20 and thence upwardly as indicated at 21, Fig. 4. The curved part 20, between the two

inclined parts

19 and 21, forms a pocket 23 in the shelf 22 at the front side of the liner to receive an article, such as a toy 24. The front side of the liner 12, at the front thereof, slopes upwardly from the point 25 to the point of the bend 18, as indicated at 26, thereby forming. a space 27 to form room for the shelf 22 and its article pocket 23. Thearticle 24 such as a toy prize, is adapted to be placed in the open end of the carton 1, and come to rest in the pocket 23 of the shelf 22. The article 24, therefore, is held in place on. the shelf 22 between the

liner surfaces

19 and 21 and between the ends of the carton. The shelf 22 is held in place by the front and rear panels or

sides

2 and 3. The liner extension 17 is of suflicient length to form the shelf 22 which lies between the top of the liner 12and the closed flaps 10 and 11, 11. The toy 24, therefore, is supported on the shelf 22 being boxed between the sides 11, 11, the top 6 and the front and

rear panels

2 and 3, after the said fiaps 10 and 11 are closed.

If desired, a protective coating or sheet of material, such as cellophane, pliofilm, or other material, may be wrapped around the finished package after the same has been closed and sealed.

The package of the invention is adapted to permit an article, such as a prize, to be inserted in a carton exteriorly of the liner, and thereby do away with the wrapping of the article separately and inserting the separately wrapped article in the inside of the liner or bag in which the material is received and bagged. The cost of packaging is reduced, and the costof enclosing the article or prize is done away with.

The invention further provides relatively simple means for encasing an article. within the container exteriorly of the liner and in apositionsuch that it is readily available, and may be seen immediately, upon the opening of the top flap 10.

Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention or sacrificing any of its advantages, and the right is hereby reserved to make all such changes as fall fairly within-the scope of the following claim.

This invention is claimed as follows:

A package comprising a tubular liner made of a single sheet of material and containing a substance, said liner having front, back and side walls and top and bottom ends defining an enclosure, one end of said container having the front, back and side walls folded and sealed upon each other defining a flat projecting end, said front wall having an inclined portion extending upwardly toward said back wall and terminating at the inner end of said projection, said projecting end being bent toward said inclined portion and then reversely bent to define a shelf at one end of the liner, said shelfhaving a configuration which is substantially equal to the cross-section area of the liner, an'outer carton of a cross section area similar to the cross section area of the liner and completely enclosing the filledliner and shelf, whereby said shelf definesv a chamber with the corresponding end of the carton, and an article in said chamber supported on said shelf.
