Application"- November 7, 1947, Serial No. 784,594

3: Claims.

This invention relates to improvements; car;- tons. of the type shown and described in my copending application serial Number 'Z"7/l,ll5-,v filed September 15, 1947, now Patent No. 2,523,688.

It is one. of the principal objects of the present invention: to provide a carton. of. the type above referred to but which is reinforced by double wall thickness about three of its sides at its upper half where the carton is ordinarily gripped by a user during the opening and pouring operations.

A further object is the provision of means formed in the top wall of the carton formaintaining one wall of the spout in. surface to sur facewiping contact with one wall of the carton throughout its operative: range from: open, to closed positions to prevent leakage between the wall of the spout and the wall. of the carton.

A still further object is the provision. ofv means for locking the pouring spout; in a. closed position against unintentional opening.

Another object is the provision of a carton. of this character which may be. cut and scored from a single blank of material. and quickly and. con.- veniently folded into final form.

These and other objects will appear as my invention is-more fully hereinafter described the following specification, illustrated in the accompanying drawing and finally pointedout in: the appended claims.

In the drawing: 7 I

Figure 1 is a plan View of asheet of blank car-- ton material cut and scored for foldin intoa combination carton and pouring spout, in accord.- an ce with my invention. Figure 2 is a perspective view of theiolded carton showing the pouring spout in. an: open position.

Figure 3 is a perspective view taken approximately in the direction of the arrow in Figure 2'.

Figure 4 is a fragmentary sectional view of the bottom end of the carton illustrating an elevated bottom wall.

Referring now more particularly to the drawin Figure 1, reference numerals I, 2, 3, and 4 indicate four panels constituting the vertical walls of the carton when folded and are defined by longitudinal fold lines 5 and 6, and transverse fold lines I, 8, and 9'. The top wall of the carton is formed by two end flaps H1 and II foldable about the fold line 5. The bottom'wall of the carton is formed by inwardly foldable end flaps I2, [3-, I4, and I5 preferably oi unequal lengths as shown, and scored as at [4A. and ISA.

An auxiliary fiap I6 is formed integral with thepanel l and is foldable at right anglesthereto about a fold line I! for engagement with either the inside or outside marginal edge of the panel 4 when the carton is folded into final form.

The end flap 10 of the top wall is formed with an integral projection 18 foldable about aconti-nuation of the fold line 1. The other top end 2 flap II is likewise formed with an extension l9 foldable about the fold line 9 and this extension is formed with an integral projection 20 foldable about a fold line 2|. The projection 20 is formed on a greater radius than that of the wall 23 of the spout. Gne wall 23 of the pouring spout, generally indicated at 24, is formed. integral with the" panel 2 and cutout from the corner of the flap H] by perforations IDA as shown. The opposite wall 25 of the spout is foldable, about a continuation of the fold line: 8, at right angles to the wall 23 to form. the spout as shown in Figures 2 and 3-. The outermost; corner of the wall 25 is formed with a projection. 26. to serve as a limit stop, for the opening movement of the spout when the. projection comes up and bears against the underside of the flap II when the carton is in completely folded form. The lowermost edge of the wall 25 of the spout is tapered as indicated at 2'! to correspond with. the tapered edge of the panel 3 to guide thewall 25 of the spout to the inside of the wall 3 of the carton when it is being folded. V

In assembling or folding the carton into final form, I bend the panels l, 2, 3, and 4 about the fold lines 1; B, and 9 into right angular relation to each other to form the carton in. box formation; The auxiliary flap Iii is: then secured. by an adhesive to the marginal edge of the wall. 4. Following this thebottomend flaps [2,, l3, l4, and I5 are folded inwardly about the fold line. 6 then folded over on themselves between. the fold lines 6,. MA, and LEA to form the elevated bottomwall illustrated in Figure 4. The folded over portions of. the flaps, and the overlapping flaps may be. secured to each other by the application of an, adhesive. The folding thus far moves the panels, [9 and ,H into a position directly opposite to the panels Ill and [8. Following thisgthe wall 2.5 of. the spout, is moved about the fold line 8, at right angles to, the wall 23 of. the spout, and the wall 25 is then in position to, be moved. down.- wardly on the interior of. the carton. against the wall 3.. The: panel I l is thenfolded downwardly which places the. extension [9 against the; out,- side of the wall 3 and theprojeotion 20* against the outside. of the wall 2 with its upp r edge along the hinge line. 5 of the: pouring spout. The flap l0 is moved downwardly to overlie the flap II and the extension [8 is folded. against and secured to the outside of the wall I. The flap. II

is formed with a slot. 29 adapted to embracethe wall 25 of the spout and to serve as a guide. in maintaining the wall in close and leakproof wiping contact with the wall 3 throughout the operative range of. movement of the spout. The limit double wall thickness, and also that portion of another wall 3 directly beneath the hinge line of the spout and over an area which is normally gripped by a user in the opening and. closing operations of the spout. The reinforcements l9 and 20 also prevent any distortion of this corner of the carton which might tend to unseat or disturb the flat surface-to-surface contact of the wall 25 of the spout with the wall 3 of the carton, as aforesaid.

As a means of locking the spout in a closed position against accidental opening, I provide a projection 30 at the central upper corner of the spout for frictional engagement with the inner end of the slot 29.

For manipulating the spout from a closed to an open position, I form a projection or tab 3| on the wall 23 of the spout. The outer edge of the wall 23 of the spout is defined by the perforated line lflA so that when the top end of the carton is folded the spout will remain closed until ready for use.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention.

Having thus described the invention what I claim as new and desire to protect by Letters Patent is:

1. A carton formed from a single sheet of material formed with parallel sets of folding creases extending perpendicularly to each other in intersecting relationship defining a central rectangular portion folded along certain of said parallel creases providing four side walls of said carton, end flaps along two opposite edges of said portion folded to overlying relationship providing a top wall and a bottom wall for said carton, a

semi-circular tab, afirst half of which is formed out of one of the flaps of said top wall adjacent the juncture between two adjacent sides of said carton and in continuation of one of said two adjacent sides and the second half of which is in a plane parallel with the other of said two adjacent sides and is integral with said tab being foldable through its center along a line in continuation of the folding crease defining the juncture between said two adjacent side walls to form a pouring spout in which the two halves of said tab are at right angles to each other with said second half integral with and joined to said first half only, one of the flaps forming said top wall being formed with a lateral extension extending over and secured to one of said two adjacent side walls adjacent said tab and said extension being formed with a projection extending over the other of said two adjacent sides adjacent said tab and secured thereto whereby 'said two adjacent sides are reinforced adjacent said tab by said extension and said projection.
