Patented Mar. 23, 1943 2,314,631 comma Don Ray, Beverly Hills, CaliL, assignor to Arden Farms 00., Los Angeles, Calif., a corporation of Delaware Application August 21 1939, Serial No. 291,213 Claims. (Cl. 229l4) The present invention relates to a container made of paper or other suitable material and adapted for the reception of candy, cookies, cheese, ice cream, dried fruits, popcorn and numerous other articles. Generally stated, the container of this invention is characterized by being of polygonal cross-section and by being provided with separately removable top and bottom portions. It is further characterized in that a container of relatively large volume is obtained by the use of a minimum quantity of paper or other material employed in constructing the carton.

An object of the present invention, therefore, is to disclose and provide a container which is distinctive in form and appearance and which may be readily and cheaply manufactured.

A further object is to provide a container of polygonal cross-section having separately removable end portions or top .and bottom.

A still further object is to provide a container having integral means for facilitating entry into the package.

Other objects, uses and advantages will become apparent from the following description.

In order to facilitate understanding. reference will be had to the appended drawings showing certain illustrative forms.

In the drawings:

Fig. 1 is a perspective view of a container made in accordance with this invention.

Fig. 2 is a perspective view of a smaller container made in accordance with this invention.

Fig. 3 is a plan view of a precut blank of material adapted to form the side walls of the container.

. Fig. 4 is a plan view of an end or bottom portion.

Fig. 5 is a perspective view of a container with one end or top removed.

Fig. 6 is a plan view of a blank for use in making liners in the container.

Fig. 7 is an enlarged view of a portion ofthe liner in preformed condition.

Although the present invention is adapted to the production of any polygonal package or con- 'tainer (having either an even or an odd number of sides in excess of four), best results appear to be attained by adapting the invention to octagonal packages or packages having an even number of side panels. In the drawings an octagonal container is shown comprising in general a side wall member, generally indicated at i, and end portions 2 and 3 which are separately til removable from the side wall member I. Al-

though the illustrative container has a section representing a regular, equilateral polygon, polygonal containers having sides diilering in length can be made; for instance, an eight sided container may have two opposing sides appreciable longer than the three sides at each end portion of the container.

The side wall member l'preferably comprises a continuous strip of material having a plurality of transversely extending parallel panels thereon, such panels being delineated by score lines or crimp lines extending transversely of the strip. For example, the continuous wall member I shown in Fig. 3 comprises a strip of material having panels I I, l2, l3, ll, etc., thereon, these panels being delineated by the score lines 18, ll, l8, etc. As shown in Fig. 3, the ends of the continuous strip containing eight panels such as H to ll have been connected together so as to form the overlapping portion indicated at 19, this overlapping portion being then glued to the inner surface of the strip. In Fig. 3 this continuous wall member having its ends joined or connected together is shown in a flattened out posi-- and 2|. The ends of certain of the panels terminating at these side margins may be provided withintegral tongues having outwardly diverging edges extending from these side margins For example, panel H may carry the tongues 22 and 23 at'opposite ends thereof, such tongues being provided with the outwardly diverging edges 24, 25, 26 and -21. Crimp lines 28 and 29 in alignment with the margins 2|] and 2| may be provided for the purpose of facilitating subsequent folding of the tongues 22 and 23.

When containers having even number of sides or side panels are being made, only alternate panels are provided with the tongues. As shown in Fig. 3, panels II and 13 are clearly visible and are provided with tongues, the panel 13 bearing the tongues 30 and 3!, The inner sides of tongues attached to the panel beneath panel ll are indicated at 32 and 33.

Means are carried by the wall member i for facilitating attachment of the end portions. Such means may comprise slots, such as the slots 3| and 35 formed in the panel 12 adjacent the margins III and 21. Similar slots 36 and 31 are formed in the panel II. In other words, alternate panels may be provided with foldable tongues extending from their ends whereas in- .form a polygonal container.

termediate panels are provided with slots or other means adapted to cooperate with the end portions of the package in forming a completed container.

One or the end portions 2 is indicated in Fig. 4. It will be noted that each end portion comprises a central field 46 delineated by the margins 4|, 42, 43, etc., and by intermediate score lines or crimp lines 44, 45, etc. The length of the edges 41, 42, 43, etc., should be substantially equivalent to the length of the score lines 44, 45, etc. The margins 4| aswell as the score lines 44 will hereafter be referred to as field lines. Alternate field lines preferably carry outwardly extending looking tangs. For example,- the score lines 44, 45, etc., may carry the locking tangs 46 and 41, each of such locking tangs including a main portion 48 substantially as long as the length of the field line 44 and of a width approximating the distance between the margin 20 and the slot 36 formed in the wall member I. Such main portion 48 may then be provided with a spear head 49, the maximum length of this spear head being substantially equivalent or slightly shorter than the length of the slots, such as the slots 34 and 36 formed in the wall member.

By referring to Fig. 5 (which shows a partially assembled container) it will be noted that the fiat wall member I may be expanded so as to The various tongues, such as for example the tongue 3| attached to one end of panel 13, may be folded inwardly. It will be noted that the outwardly diverging edges of the tongue 3| are now in substantial alignment with the planes occupied by the adjoining panels l2 and I4, this tending to maintain the shape of the container.

The bottom 2 has been applied to the side wall member by folding the various locking tangs 46, 41 and the like upwardly and forcing the spear heads of such tangs through the slots in the alternative panels of the body member I. In Fig. 5 the locking tang 46 is shown inserted into the slot 36 of panel l4.

The top or other end portion of the finished container may be applied to the other end of the container shown in Fig. 5 in substantially the same manner as that described for the bottom 2.

Attention is. also called to the fact that certain of the panels may be provided with means for facilitating access to the completed, filled and sealed container. For example, as shown in Fig. 3, panel l3 (or some other panel) may be provided with a readily removable wall section. Specifically, panel i3 is shown provided with a partially perforated strip 50 defined by the perforations 5| and 52, such perforations being in parallel relation and being connected at their ends by a slot or through-cut portions of U form as indicated at 53 and 54. In the finished package, a finger nail may be readily introduced into one of the slots, such as the slot 54, and the entire removable strip 50 torn out of the panel i3, thereby permitting ready access to the inte-' rior of the container.

In some instances it may be desirable to use a liner within a container of this character. A form of liner found best suited for this purpose is shown in Figs. 6 and '7. The liner may be made of any suitable material such as, for example, paper, rubber compositions (such as those sold under the name "Pliofilm), parchment, waxed papers, or the like. By referring to Figs. 6 and '7 it will be seen that the liner comprises a polygonal field 55 delineated by the crimp lines 56, 51, 58, etc. Preferably the polygonal field 55 is smaller than the polygonal field 40 of the end portions of the package. Tongues, such as the tongues 60. 6| and 62, extend from each of these field lines and perpendicular thereto. The length of these tongues measured in a direction perpendicular to the field line, should be at least equivalent to the long dimension of each of the panels of the body member or the distance separating the margins 20 and 2| of such body member. Alternate tongues may be of a width equivalent to the length of the field lines. For example, the tongues 60 and 62 are of substantially uniform width, the width being equivalent to the length of the field lines 56 and 58.

approximately twice as wide but are provided with parallel score or fold lines such as ,the lines 63 and 64 extending from the ends of the corresponding field line 51.

Fold lines, such as 65 and 66, are also formed, these fold lines bi-secting the angle formed between perpendiculars drawn to opposing ends of adjacent field lines. 65 and 66 intersect the edges of the intermediate wider tongues, such as the edges 61 and 68 of the tongue 6|, these edges 61 and 68 terminate and define the point at which a web, such as the web 69, extends from the narrow tongue, such as the tongue 62, toward the wider tongue such as the tongue 6|.

The entire liner is thus seen to be made of a single piece of material. When forming the liner, the narrow tongues 60 and 62 are folded upwardly along their field lines 56 and 58 so as to cause the edges of the narrow tongues to overlie the score lines formed in the wider tongues. For example, the edge 10 of the tongue 62 will be caused to overlie the score line 64, the Wing 1| embracing approximately one-half of the outer surface of the narrow tongue 62. The wing of the next wide tongue, indicated at 13, will abut the edge 68, thereby forming a substantially water-tight liner capable of retaining moisture, melting ice cream, or the like. 1

These liners may be inserted into the package or container immediately prior to the application of the top. If desired, certain of the tongues, such as the narrow tongues 60 and 62, may be provided with tab end portions 15, 16 so as to partially cover the contents of the package. If still further protection is desired, a top liner may be applied before the top itself is locked with the Wall member.

Liners or bag-like containers made from a blank of material comprising a central field of any desired shape (not necessarily polygonal, but instead rectangular, square, etc.) and having tongues extending therefrom, alternate tongues being wider than the intermediate tongues (or at ieast'wider than the field line from which such wider tongues extend) may be made from a thermoplastic or thermosetting, flexible material such as Pliofilm (which becomes adhesive upon heating) and then the overlapping portions of the tongues may be caused to cement together during formation of the liner or bag-like inner container. The resulting inner liner or container is water tight. Such liner containers may be filled, under vacuum, sealed under vacuum and then exposed to atmospheric pressure. When placed in an outer protective wrapper, a finished, flavor-retaining. shipping container is obtained.

Intermediate tongues, such as the tonguesSl, are preferably Where these score lines 2,814,681 i p. 3 as the field lines and intermediate tongues being Those skilled in the art will appreciate that numerous changes and modifications can be made and that the character of the materials used may be varied in accordance with the use to whichfthe container is being adapted.- Moreover, it is to be understood that the term "score lines as vuser herein refers to any scoring, crimping, indenting or other means 01 facilitating folding or bending of the materials along predetermined lines.
