18 Claims.

My invention relates to an improvement in package, particularly applicable for use as a container for packaged goods which are to be dispensed at intervals. i

The object of the present invention is to provide a package for containing a product such as a breakfast food or the like, which may be dispensed from time to time from the package. It

. amount of the goods has been dispersed the package may again be closed to provide an effective seal for the protection of the remaining contents.

A'feature of the present invention lies in the provision of a package having a double thickness wall portion, and in providing a fiap which is originally an integral part of one thickness of this double thickness wall portion of the package. This flap may be separated along perforated lines when the package is originally opened without destroying the effectiveness of the wall. Thus the package is effectively sealed until first opened.

A further feature of the present invention lies in the provision of a closing flap which forms a part of the package wall in the original package and which may be tucked within the wall in order to seal the package after it has once been opened.

A further feature of the present invention lies in the provision of a shoulder within the body UNITED STATES PATENT oFFicE" set' forth in the claims.

Figure 14is a diagrammatic view of the package before the same has been folded. l The package A is shown substantially rectangular in general formation and is preferably formed with an outline shape similar to that shown in Figure 14- of the drai rings. The packageincludes an outerifront wall to which is connected along a fold line ll to a side wall i3.. The

Figure '10 is a view similar to Figure 9 show-- .ing two opposed a top fold line 3| to the top closing flap 32.

side wall I2 is connected along a fold line |3 to the rear wall l4. The rear wall H is connected along a fold line |5.to the side wall l6. This side wall I5 is in turn connected along the fold line H to the inner front wall or anchor.- ing panel l9.

The front wall In is connected along the fold line 20 to a bottom closing flap 2| and is connected along a fold line 22 to a top closing flap 23. The side wall I2 is connected along a fold line 24 to a bottom closing flap 25 and is also connected along a fold line 25 to a top closing flap 21. i

The rear panel I4 is line 23 to the bottom closing flap 30 and along The side 'panel I6 is connected along the fold line 33 to a bottom closing flap 34 and along a fold 'line 35 to a top closing flap 35.

The panel I3 is not provided with any closing flaps, but is merely adhered in overlapping relation to the panel III. A surface of the wall or panel l9 may be gummed or glued by adhesive 33 to the inner surface of the panel H) in assembled position of the box or package. A section 31 of the panel I3 is left free of glue or adhesive 39 for a purpose which will be later described in detail.

The panel I0 is slotted at 40 to define a substantially rectangular tab 4|. A notch 42 is provided in the free edge of the panel l3 and a perforated line 43 connects the slot 40 to the notch 42. A perforated line 44 extends across the closing flap 23 connecting the upper extremity of the slot 40 with a point directly across the closing flap 23. The perforated line 44 extends parallel to the folding lines ll, [3, l5, and H in the died-out form of the box illustrated in Figure 14.

A perforated line 45 extend across the closing flap 32 and this perforated line 45 extends parallel to the perforated line 44 in the died-out formation of the container. In folded condition of the container the perforated lines 44 and 45 are virtually superimposed.

connected along a fold A surface of the closing flap 32 is gummed or glued with adhesive and strips of adhesive 41 and 43 are applied to the surfaces of the closin flaps 21 and 36. In forming the box or package A, the package is bent along the fold lines l3. l5 and I1 until a rectangular tube i formed with the panel I! overlying the panel l0 and being adhered to the surface thereof. The closing flaps 21 and 35 are then folded down until the edges thereof engage against the upper edge of the inner panel IS. The closing flap 23 is then folded down upon the closing flaps 21' and 33 and is adhered thereto. It will be noted that the closing flap 21 is adhered only to the section 53 of the closing flap 32 which-lies to the right of the per-.

. forated line 45, when viewed as in Figure 14 of closing flap 23 and is adhered thereto over theentire surface area. The sealing operation may be assisted by the support beneath the closinfl flaps 21 and 35 by the marginal edge of the inner panel l3. 7 I

The contents of the package may be inserted and the opposite end of the package may then be sealed. In sealing the lower end of the con-.

tainer the closing flaps 21 and 34 may first be folded so as to engage against the marginal edge 52 of the panel IS. The closing flap 20 may then be adhered to the glued surfaces 53 and 54 of the flaps 25 and 34 and the closing flap 30 may be folded down and adhered tothe glued or gummed surface 55 of the closing flap 2|. In this sealing operation the edges of the flaps 25 and 34 bear against the houlder provided by the edge 52 of the panel l9, thus providing an internal support against which the pressure of the sealing apparatus may be exerted. Thus,

'even though the contents of the package may be granular or flaky and not of sufficient body to provide a resistance to external sealing pressure, the shoulder edge 52 provides such support during inward pressure against the sealing flaps.

The manner in which the package is formed has now been described. This package, when sealed as described, will appear as shown in Figures 1 and 6 of the drawings. When it is desired to open the package, a thin instrument such as a knife blade B is inserted between the tab 4| and the outer surface of the inner panel l9. By slightly twisting the blade 3 the panel I0 is broken along the perforated line 43, separating the tab 4| from the remainder of the panel In. The next step in opening the container is to grasp the tab 4| and pull the same upwardly, tearing the closing flaps 23 and 32 along the perforated lines 44 and 45 respectively. In Figure 3 of the drawings the package is shown after this operation has taken place. The closure formed, and indicated in general by the numeral 55, is still hingedly connected to the remainder of the package along the fold line 3|. The closure 55 includes the section 5| of the closure flap 32, a section 51 of the closure panel 23, which section lies to the right of the perforated line 54 in Figure 14 of the drawings, together with the tab 4| hingedly connected thereto along the fold line 22.

In order to remove a portion of the contents of the package, it is then only necessary to fold the flap 35 upwardly into the position shown in Figure 4 of the drawings, whereupon the contents may be poured from the package. When it i desired to close the package the closing flap 35 is again folded down asillustrated in Figure 3 of the drawings and the tab 4| ofthe closure 53 is inserted between the edge of the closure flap 35 and the inner face of the panel l9. To make this insertion easily possible, a recess 53 may be provided in the edge of the closing flap 35, into which the tab 4| may be easily inserted.

Figure 6 of the drawing illustrates sectionally the top of the package A, while the same is sealed, as shown in Figure 1 of the drawings. Figure '1 of the drawings illustrates the top after the closure has been broken away therefrom, as shown in Figure/3 of the drawings. Figure 8 illustrate the tab 4| reinserted into the container, as in Figure 5 of the drawings.

Figures 9 through 13 show the manner in which the bottom of the box is closed. Figure!) shows one of the side flaps 34 folded into closed position, while the remaining flaps 2|, 25, and 33 extend upwardly. Figure 10 is a similar view showing both of the side flaps 25 and 34 in folded position, while the remaining flaps 2| and 33 project upwardly. Figure 11 shows the arrangement of the elements after the fiaps 25 and 84 have been folded down and prior to the folding of the flaps 2| and 30. Figure 12 shows all of the flaps 2|, 25, 30, and 34 in folded position. Figure 13 is a somewhat enlarged view showing the manner in which the flaps 34 and 25 fold against the shoulder edge 52 of the panel l9 and are supported thereby during the sealing operation.

I have described the package as comprising certain closure flaps and have described a specific order in which these flaps are folded. Obviously others of the flaps may first be folded and the particular sequence of folding the closure flaps may be varied to some extent without changing the operation or the feature of the invention.

In accordance with the patent statutes, I have described the principles'of construction and operation of my package, and while I have endeavored to set forththe best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
