Cvacho, Chesterfield County, Va, assignor to Reynolds Metals Company, Richmond, Va., a corporation of Virginia Filed Sept. 25, 1964, Ser. No. 399,183 12 Claims. (Cl. 229-53) This invention relates to an improved container construction as well as to the method of making such a container construction or the like.

It is well known from the copending patent application Serial No. 336,693, filed January 9, 1964, and entitled, Container Constructions and Method for Making the Same or the Like, that a container construction can be formed by providing a rigid board means folded in any suitable manner to provide opposed side wall means and opposed top and bottom wall means with the resulting opposed open end wall means closed in a suitable manner by narrow, flexible tape-like means whereby the tape-like means and rigid board means cooperate together to define a product-receiving compartment in the container construction.

However, this invention provides improved means for interconnecting the narrow tape-like means to the rigid board means to complete the container construction of the above type.

Accordingly, it is an object of this invention to provide an improved container construction having one or more of the novel features set forth above or hereinafter shown or described.

Another object of this invention is to provide an improved method of making such a container construction or the like.

Other objects, uses and advantages of this invention are apparent from a reading of this description which proceeds with reference to the accompanying drawings forming a part thereof and wherein:

3,269,642 Patented August 30, 1966 Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings, because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention.

Referring now to FIGURE 1, an improved container construction of this invention is generally indicated by the reference numeral 20 and comprises a rigid board means 21 folded in a manner hereinafter described to define a pair of opposed side wall means 22 and 23 interconnected together at the bottom edges thereof to define a bottom wall means 24 and having the top edges thereof brought together to define a top wall means 25 whereby the rigid board means 21 defines a pair of opposed open end walls 26 and 27 of the container construction 20 which are subsequently closed by narrow, flexible tapelike means 28 of this invention in a manner hereinafter described, the container construction 20 being temporarily closed by another tape means 29 in a manner hereinafter described.

The tape-like means 28 and rigid board means 21 cooperate in a manner hereinafter described to define a product-receiving compartment 30 in the container construction 20 in the manner illustrated in FIGURE 2 so that the desired product 31 can be completely sealed closed in the container construction 20 for a subsequent sale to the ultimate consumer, the rigid board means 21 providing suitable projective material for the product 31.

One method of forming the container construction 20 of this invention will now be described and reference is made to FIGURE 3 wherein it can be seen that the rigid board means 21 comprises a substantially rectangular blank divided into two equal sections 32 and 33 by a transversely disposed score 34.

The tape-like means 28 of this invention comprises narrow rectangular strips as illustrated in FIGURE 4 and has one side thereof provided with heat scalable material. For example, each strip 28 can comprise heat scalable polyethylene or the like either by itself or in a laminated structure as desired.

The heat scalable side of the strips 28 are disposed against the inside surface of the rigid board means 21 in the manner illustrated in FIGURE 5 whereby the outer edges 35 of the strips of material 28 are disposed substantially in superimposed relation on the opposed side edges 36 of the blank 21. In this manner, the outer edge means 35 of the strips of material 28 are adapted to be heat sealed to the interior surface of the blank 21 to define heat sealed seams 37 in the manner illustrated in FIGURE 5.

Thereafter, the strips of material 28 are folded outwardly in the manner illustrated in FIGURE 6 to bring the other edge portion 38 thereof outboard of the rigid board means 21 in the manner illustrated in FIGURE 6 whereby the assembly illustrated in FIGURE 6 can be folded on the score 34 to bring each tape-like means 28 into superimposed relation in the manner illustrated in FIG- URE 7.

With the assembly folded in the manner illustrated in FIGURE 7, each tape-like member 28 is heat sealed to itself at the edge means 38 thereof to define longitudinal heat sealed seams 39 extending from the bottom edges 49 of the rigid board means 21 to the top edges 41 thereof. In this manner, the top edges 41 can be separated from each other in the manner illustrated in FIGURE 8 whereby the tape-like means 28 cooperate with the board means 21 to define the product-receiving compartment 39 in the assembly illustrated in FIGURE 8 so that the product 31 can be dispensed therein from suitable dispensing means 42 to fill the compartment 30.

After the compartment 30 has been filled, the top edges 41 of the board means 21 are brought adjacent each other in the manner illustrated in FIGURES 1 and 9 and are sealed in their closed position by a tape-like member overlapping the edges 41 thereof so as to be secured to the opposed side wall means 22 and 23 and the be heat sealed to the seams 39 of the strips of material 28 to completely close the container construction 20 whereby an attractive and marketable container construction 20 is provided in a simple and effective manner.

When the ultimate consumer desires to open the package construction 20, the tape-like means 29 can be removed so that the top edges 41 of the side wall means 22 and 23 can be moved away from each other to open the chamber 31 to dispense the product out of the container construction 20, the tape means 29 being reusable, if desired, to reclose the container 20 when only a portion of the product 31 has been dispensed therefrom in the above manner.

While the container construction 20 of this invention has been illustrated as having the bottom wall means 24 thereof formed by a single score 34 in the rigid board means 21 in the manner illustrated in FIGURE 3, it is to be understood that a flat bottom wall could be provided for the container construction. For example, reference is made to FIGURE wherein another container construction of this invention is generally indicated by the reference numeral 43 and parts thereof similar to the container construction are indicated by like reference numerals. However, the rigid board means 21 illustrated in FIGURE 10 has the bottom edges of the side wall means 22 and 23 integrally joined to a flat bottom panel 44 "formed in the rigid board means 21 by spaced parallel scores 45 and 46 in substantially the same manner as set forth in the aforementioned copending patent application.

While the tape-like means 28 of this invention has been described as being secured to the inside surface of the rigid board means 21 to provide the container construction 20 or 43 of this invention, it is to be understood that the tape-like members 28 could be secured to the outside surface of the board means 21 to provide a container construction having certain of the features of this invention.

In particular, reference is made to FIGURE 11 of this invention wherein another container construction is generally indicated by the reference numeral 47 and comprises a rigid board means 21 formed in a manner similar to the rigid board means 21 of FIGURE 3.

However, the tape-like members 28 have the edge means 38 thereof secured to the outside surface of the rigid board means 21 in the manner illustrated in FIGURE 12 whereby when the lower portion of the assembly illustrated in FIGURE 12 is disposed on the upper portion thereof by folding the rigid board means 21 on the score 34, the edge means 35 of the strips of material 28 will be superimposed on each other and can be heat sealed together to provide longitudinal heat sealed seams 48 at the opposed end wall means 26 and 27 of the container construction 47 whereby the strips of material 28 are secured to the outside surfaces of the board means 21.

The containerconstruction 47 is adapted to be closed and opened by the sheet means 29 in the manner previously described.

While the container constructions of this invention have been described as having the tape-like means heat sealed thereto and to itself, it is to be understood that the tape-like means could be secured to the rigid board means and to itself by other adhesive means, as desired.

Therefore, it can be seen that not only does this invention provide an improved container construction having many novel features, but also this invention provides an improved method for making such a container construction or the like.
