In Canada May 20; 1940 11 Claims.

Our invention relates to improvements in containers and more particularly to those of the carton type incorporating a pouring and measuring means for the contents, and an object of the invention is to devise a container which, while permitting the combined pourer and measurer to be disposed entirely within the confines of the container, will lend itself readily to economical production such as is essential in carton type commodity containers and will be capable of being collapsed or packed fiat instead of set up during shipment and storage prior to use.

A further object is to originate a container in which the measurer or contents receiving pocket will automatically position itself therein upon the container being transposed from its collapsed position into its set-up position.

Yet other objects are to provide a container in which it and its pourer and measurer are fabricated integrally from a single sheet of paper or cardboard, and in which the resultant container may be filled and sealed by the orthodox machines at present in use for containers of this type.

With the above and other objects in view which will hereinafter appear as the specification proceeds, our invention, in its preferred embodiment, consists of the construction and arrangement all as hereinafter more particularly described and illustrated 'in the accompanying drawings in which- Fig. 1 represents a plan view of the blank from which the container is. formed.

Like characters of reference indicate corresponding parts in the different views of the drawings.

In the embodiment of our invention as illustrated th container is of the rectangular paper carton type with flap closures for both top and bottom and adapted to be collapsible so that it may be packed fiat prior to being used. When required for use the container is designed to be opened up and filled and sealed'by standard machines ordinarily employed for packaging cartons of this type. It comprises an integral blank of paper or cardboard A suitably scored and out to form it into side wall portions 1 and 2 separated by an end wall 3, the opposite side edges of the portions l and 2 to those adjacent to the portion 3 having respectively similar end wall portions 4 and 5. Top and bottom end flaps 6 and 1, 8 and 9,, l0 and H, and I2 and I3 are provided respectively on the upper and lower ends of the portions I, 3, 2 and 5. The construction so far is orthodox in any carton of the above referred to type.

A short distance from the end of the flap 6 adjacent to the end wall 4 is an arcuate incision l4 located intermediately of the Width of the flap and its ends connected to lateral score lines [5 extending to the side edges of the flap 6. The score line l5 extending to the flap side edge adjacent the side wall I connects with a perforation line it at right angles thereto continuing to the adjacent corner of the end wall 4.

A lateral score line I'l" positioned the same distance from the end of the flap l0 adjacent the flap [2 as the score lines l5 are spaced from the from the above referred to ends of the flaps l and 6 respectively.

g 2,350,925 end of the flap 6 adjacent the end wall 4 extends when the container is swung to set-up position, the side wall 2 of the container engaging first of all the extension 28 and then the point of folding between the extension 28 and 21 will finally press upon the fold between these extensions and cause them to become aligned with one another, thus automatically causing the bafile forming flap 2| to assume normal set-up position when the container is set up from its collapsed position. The extensions 21 and 28, when the flap 2| is in the bafile forming position, are in the An additional rectangular flap 2| is provided extending out from the free edge of the end wall 5 and its upper edge is preferably coincident, with the perforation lines l8 and |9.j Such flap 2| is only joined to the end wall 5 at its lower portion below a transverse score line 22disposed intermediately of the height of such flap 2|. From a g score line 123 extendingfrom theojunction of the free. edge ofthe flap 2|. with-the. score line' 22 to the corresponding upperrcorner of the flap 2| a further flap 24 extendsoutwardly and inclinedly downwardly towards its free end edge. The outer portion of such flap 24 is rectangular and corresponds in width to the flap 2| and the end wall 5. A score line extends upwardly from the junction of the score line 22 with the lower end of the score 1ine.23 and parallel to the free end edge of the flap 24 and a second upwardly extending score line 26 substantially bisects the angle formed by the score lines 23 and 25, the lines 23, 25 and 26 forming a foldable web connection between the flaps 2| and 24 which constitute in effect joining extensionsof said flaps.

In forming up the container the flap 2|, which has previously had the flap 24 folded onto it along the score line 26,i'i's folded onto the end wall 5 and the part below the score lin 22 is gummed to such end wall, the flap 24 which is interposed between the' flap,2| and the end wall 5 is also gummedto the end wall 5, the parts 21 and'28 of such flap 24 being in superimposed relation and lying against the'adjacent side wall 2 as illustrated in Fig. 3. The container is then suitably folded on the score line between side wall 2 and end wall 3 so that the side wall 2' and end wall 5 together with the'fold edand glued flaps 23 and 2| are superimposed on end wall 3 and side wall I. Then end wall 4 isfolded over and glued onto end wall aan of wh'ichcan'be done on a standard foldingand gluing machine. 7 'Whenit is desired to use the container it is only neces'sary to set it up in rectangular form when the upper part of the flap 2! will be autom'atically swung out as illustrated in Figs. vl. 6. 8, 9 'ahd'lO wherein it is inclined upwardly and inwardly from the end wall 5 about the score line 22Lconstituting a baiile B having its upward edge disposed in spaced relation to the top of the container. andwith the end wall 5 forming a pocket C for entrapping a predetermined quantity of the contents of the package; ,In this connection. as noted particularly in Fig. 4, the extensions 21 and 28 constitute .a foldable web between the flap 2| and flap 24 and in the collapsed position of the container are folded one upon the other and lie between the side walls land 2 of the container. the baffle forming flap 2| lying'upon the end wall 5. Since'the extension 28 connects directly with the flap 24 whichis glued or otherwise secured to the end wall 5 and the folded extensions 28 and 21' overlie'the side wall 2 when the container is in its collapsed position, it will be appreciated that same plane instead of super-imposed and side wall 2 of the container in bearing engagement with the extensions maintaining them in the same plane When the container is in set-up position, and such bearing or pressure engagement serves to hold the baffl in its normal set-up position.

The top of the container is now closed by inturning the end flaps 8 and I2 and then the flaps l0 and 6, the fiap 8 lying uppermost and such flaps being gummed together to form an effective topclosure for the container. The container is then filled and the lower flaps 9 and I3 and and H inturned and secured together to form the bottom closure of the package.

Alternatively in some methods of packaging the bottom may be closed first and the top last after the contents have been inserted.

When it is desired to dispense the contents of the package the perforation lines IB, I8 and H! are completely severed by the user, the tab 29 resulting from the incision I4 is pried up and held in position by the fingers while the end portions of the flaps 6, l0 and I2 are pushed down into the position illustrated in Figs. 8 and 10 wherein such end portions form a laminated bafile D depending into the pocket C in spaced relation to the baffle B and the end wall 5 being interposed between these two parts. A discharge passageway E is constituted between the baffle D and the end wall 5. The buckling of the baffl D is pre vented by the above referred to holding of the tab 29 by the fingers, and the prying up of such tab tends to start the turning down of the bafile D.

Such bafile is sufiiciently rigid to remain substantially in its proper position when once bent down into such position.

The combined pourer and measurer in the container functions on the same principle as the structures disclosed and claimed in our United States application Serial No. 314,522, filed January 18, 1940, and in our copending United States application Serial No. 331,196, filed April 23, 1940.

When the package is primarily inverted so that the corner with the discharge passageway E is lowermost a predetermined amount of the contents'such as powdered soap, or any reasonably fine comminuted material flows in between the baflie B and the bafile D. Upon the container being restored to its normal upright position such quantity of material is entrapped and falls down into the pocket C. When the container is again inverted this same quantity of material is discharged through the passageway E. IAS this particular quantity of material is discharged another and substantially identical amount flows in between the two baflles. Thus alternately inverting and turning the package upright successively dispenses substantially equal quantities of material from the container until the same has been entirely emptied.

It is obvious that by changing the length and/ or the inclination of the baffles B and D, the amounts or; commodity dispensed from the. container can bevaried. P

An alternative form of construction such as illustrated in Figs. 11, and,12 might be employed. This form of construction is substantially the same as that previously described but inaddition to the flap 2|, the extensions 21 and Hand flap 24, there is provided an extension 21a.whichconnects with a. portion of flap 2| alongthe fold line between flap.2,l andend wall 5, the extension be.- ing cut from the materialof end wall 5.

The upper and lower edges 21b and 210 of the extension 21a are cut on an incline as showmthe incline of thelower edge 21c beingsuch that when the container has been moved from its. collapsed toits set-up position and the baflle B, formed by the flap 2|, is disposed, in its inclined operating position, the edge 210. of the extension 21a will abut the endwall 4and willthus serve as a means of holding the baflleB more firmly.

In all other respects the bafile B and its as sociated structure operate in exactly the same manner since the additional extension 21a will, in the collapsed position of the container, liein its normal recess in the endwall portion 5 and will swing. out from said recess when the baffle B is moved to its operative position at the time that container isbeing set-up from its folded position. In the operative position, as is apparent, the extension Z'Ia will lie along the interior surface of side wall I ofv the container parallel thereto and parallel to the extensions 21 and 28 which then lie ina common plane and along. the interior surface of side wall 2 of the container, the extension 28 normally being glued to the side wall 2 of the container and forming the means for. causing the bafile B to assume its inclined position as the container is set-up from its collapsed position.

The extension 21a may also be formed with a notch 21d such that when the bafile D is turned downwardly as shown in Fig. 12, the lower edge of this bafile will enter the notch and form a further means of reinforcing the baflle B when it is in its inclined operative position.

Ordinarily the flap 24 may be of a width corresponding to the width of end wall 5. However, where the construction is so formed as to include the extension 21a cut out from the end wall 5 the flap 24 is made narrower, so that it will lie on the end wall 5 alongside of the extension 2111 or the cut-out in wall 5 from which the extension is formed.

From the above description it will be apparent that we have devised a simple and efiective container for commodities incorporatin a combined pourer and contents measure which can be manufactured at practically the cost of the present package of the same type and unequipped with such improvement. Furthermore, our container can be filled and sealed by existing equipment employed for this purpose.

Many modifications may be made in the invention without departing from the spirit of the same or the scope of the claims. For instance, the sequence of folding the several parts of the blank to form up the container may be varied at will to suit the operation of the machines used.
