POURING SPOUT FOR STANDARD BLANKS June 3, 1958 s. sows-ram 3 POURING SPOUT FOR STANDARD BLANKS Filed May 17, 1955 2 Sheets-Sheet 2 INVENTOR ATTORNEY Unitedstates Patent a 2,837,254 POURING SPOUT FOR STANDARD BLANKS V I Saul Goldstein, San Francisco, Calif.
Application May 17, 1955, Serial No. sos,sss
2 Claims. (cl. 222-531 Such unitary structure is very desirable and economical, I
but in some instances manufacturers of paper cartons already have machinery designed to manufacture a specific form of carton blank and in order to fabricate a blank and a spout as a unitary structure it would necessitate materially changing the machinery. This is expensive and accordingly it is an object of the present invention to utilize the blank made by certain standard machinery which is already set up at the manufacturing plants and then to add the spout dispensing member.
A further object of my invention is to utilize a novel dispensing spout combination with a. standard carton blank.-
' A further object is to so shape and so proportion a dispensing spout with respect to an opening formed in one wall of a carton blank as to perform the functions of my prior patented spouts hereinbefore referred to.
Another object is to provide an opening in the wall of a carton, said opening being formed with a fold line and a free movable tab extending therefrom, said tab having adhesive on one surface thereof for connection to the bottom portion of a dispensing spout.
Still another object is to provide a pouring spout formed of relatively thicker sheet material than the thickness of the carton blank, said spout having wide wing portions adapted to frictionally bind in the incision which bounds the side edges of a retaining tab overlapping the upper portion of the discharge opening in the carton wall, where by said spout is retained frictionally in either an open or closed position.
A further object is to provide, in combination with a pouring spout and carton blank, an advertising coupon removable to expose the spout for use.
Yet a further object is to provide a pouring spout adapted to form a side seal and eliminate capillary drip down container sides.
With the above several forms of invention and other objects in view, the invention consists in the construction, arrangement and combination of parts hereinafter described and particularly set forth in the appended claims.-
In the drawings, like parts throughout the several views are given like numerals and are thus identifiedin the following detailed description.
Figure 1 is a plan view of a flat blank as made by a standard machine with an illustration of one embodiment of pouring spout opening and a novel tear-off advertising coupon; I
Figure 2 is a partial perspective view ,of the blank of Figure 1 erected with a pouring spout attached and projected for dispensing;
Figure 3 is a plan view of a novel pouring spout blank adapted for erection and insertion in the pouring spout blank of Figure 1; Figure 4 is a cross section view on section line 4-4 of Figure 2;
Figure 5 is a plan view of a portion of a blank as illustrated in Figure 1 with second form of pouring spout= mounting in a wall of the blank;
Figure 6 is a partial cross section of the second form of spout mounting as it appears when assembled for use;
Figure 7 is a third form of the spout blank mounting and opening, which basically is similar to Figure l with-'- out the tear-elf coupon;
Referring in detail to the drawings and first with particular reference to the pouring spout blank generally designated A in Figure 3. This spout blank A is formed of six parts, namely, a rectangular bottom 10, a hinge 11, triangular side wings 12 and 133, stop projectionsor tabs 14 and 15 and lap seal portions XX as hereinafter explained. The bottom 10 is bounded on three sides by fold lines 16, 17 and 18. Fold lines 16 and 17 aresubstantially parallel to each other and are perpendicular to the third fold line 18. The free edge 19 of the spout bottom 10 may be curved inwardly to assist in pulling the spout bottom '10 from the container wall for use.
The hinge 11 isconnected along the fold line 18 to the spout bottom 10 and is incised from each respective side wing 12 and 13 along the opposite side edges 20 and 21 below the fold line 18. The side edges 20 and 21 extend below the base edges 22 and 23 of each of their respectively angularly adjacent triangular wings 12 and 13. However, the free edges 24 and 25 of each respective wing resulting from the incised portions between edges 20- and 24 and 21 and 25 of the respective parts continue 4 downwardly from their respectively adjacent fold lines below the ends of the third fold line 18 of the hinge tab 11. This'extension of the wing edges 24 and 25 below liquid is being dispensed these lap sea-ls X-X prevents capillary drip downwardly along the container sides.
The lap seals X-X are made more effective by a tab 28 incised from the carton blank B at the top of the pouring spout opening in wall 29 thereof. At the top edge of the spout mounting opening is a fold line 30 along which is connected the tab 28. This tab 28 is cut or incised along each side edge 31 and 32 from the blank material and its free edge 33 is-free to swing on the fold line 30. The width of the'incision on each edge 31 and 32 is relatively more narrow than the thickness of the sheet material of the respective spout wings 12 and 13. Therefore, when the spout is pulled outward, as in Figures 2 and 4, the tab edges 31 and 32 force the wings into fluid tight sealing engagement with the side container walls 26 and 27 adjacent the spout opening.
Each of the wings 12 and 13 includes one of the stop projections 14 and 15, which engage behind the wall 29 above the retainer or seal tab fold line 30 when the spout is pulled completely from the wall. Each triangular wing has an apex thereof at the end of a respective adjacent fold line 16 and 17 at the free edge 19 of the spout bottom 10, thus the top edges or hypotenuse portions 34 and 35 of each wing slant upwardly or rearwarclly into the interior of the container from a plane level with fold line 18 at the hinge tab 11 to the fold line 30 on a higher plane level at the retainer tab 28 when the spout is out for use.
To mount the spout A to the blank B, the wall 29 in addi- Patented June 3; 1958 3 abuts the tab 28 is incised on fold lines 36 and 37' respectively at 38 and 39 to a perforated line 40. This forms a tear-01f coupon C, which is inscribed with various advertising matter or it may be used as a redeemable coupon; surface is coated with a rectangular spot of adhesive 41 equal in areato the area of hinge tab 11; The tab 11 is secured to the wall 29 by this spot ofadhesive, see Figure 4, and prior to opening the' spout the coupon C may betorn off or left on as desired depending upon its intended use as a coupon or simply as an advertisement tab.
A second form of carbon blank spout mounting is illustrated in Figure 5. This form, is identical to Figure 1 except that the coupon orv advertisement tab C on the spout bottom 10 adjacent side is coated'with adhesive 42 and the lower edge of this tab 43 is connected along a fold line'44'to the wall 29 of the'carton blank. Thus when the spout A is mounted, the tab 43 reinforces the bottom 10, see Figure 6.
A third form of spout mounting opening is disclosed in Figure 7, wherein coupon tab C and reinforcement tab 43 are eliminated and the spout hinge tab 11 is secured to adhesive portion 45 of wall 29. This form is essentially like the form of Figure 1 after the tear-01f coupon C is removed and may also be illustrated in assembled position by reference to Figure'4.
In view of the foregoing description, it is believed the operation and use of the device is clear. Although only three mounting arrangements of my novel spout are illustrated and described, it is to be expressly understood that various changes may be made withinthe scope of the appended claims without departing from the invention.
What is claimed is:
1. In a carton having a rectangular spout opening in one wall thereof with a spout holding'tab having one edge thereof hingedly connected to the upper edge of said opening and the opposite side edges of the spout holding tab being parallel with respect to each other and being free of: the opposite side edges of the opening and in closely Below the line 40. the interior side of the wall:
4 spaced relation thereto; a' single blank pouring sp'oiit'corriprising a generally rectangular bottom wall and opposite triangular side walls relatively thicker than the space between the side edges of the said spout holding tab and the side edges defining said opening, said rectangular bottom wall of the spout being connected hingedly by fold lines along its opposite side edges to said respective triangular side walls, said bottom wall of said spout being formed with a bottom section'defin'ed by a transverse fold line, said section being secured to the inner face of said carton wall below said opening, and said spout being selectively swingable on said transverse'fo'ld line with each of the respective sidewalls thereof frictionally engaged between each of the respective opposite side edges of said spout holding tab and the respective corresponding edges of said opening to and from the pouring position of the spout, whereby the respective side edges of said spout holding tab cooperate when said spout is pulled to pouring position to frictionally bend against each respective inner side of each of the triangular .side walls of said spout, thereby holding the same to a set pouring position.
.2. The pouring spout formed according to claim 1,- wherein said carton wall at the lower edgeof said openingis formed with a reinforcement tab which is bendable'on a transverse fold line into angular position, said tab being secured to the exterior surface of the bottom Wall of the spout with their respective transverse fold lines contiguous.
