17 Claims. (Cl. 294-872) This invention relates to a carrier and cover for milk cartons of the type that are vertically elongated and rectangular with substantially flat, rectangular tops.

Cartons of the above type are now commonly employed in quart sizes and smaller, but usually not in larger sizes due to their material and to the strains imposed by their contents. Other considerations also dictate a restriction to a size not larger than the quart size. However, many persons wish to purchase a half gallon or a gallon of milk, or other beverage that may be in such cartons, at one time, and the present invention makes it convenient to do so in a unitary package.

One of the objects of this invention is the provision of a carrier that will hold a plurality of cartons of the above type together as a unit, and that will also provide a convenient means for carrying said cartons.

In certain localities, the use of milk containers not having protective caps or covers over their sealed tops, is deemed objectionable for sanitary reasons. These objections are particularly directed to such containers as have flat tops on which dust and impurities may rest and collect. The rectangular flat upper ends of milk cartons have the dispensing opening in their said upper ends, at one corner, and a closure seals said opening when the carton is filled. Usually the upper surface of such tops are slightly recessed thereby making them traps for dust and impurities.

One of the objects of the present invention is the provision of a cap or cover adapted to be quickly locked over the top of a container of the type hereinbefore described, and which cover protects the top of one or more of said cartons.

Another object of the invention is the provision of a protective cover for one or more pairs of cartons of the type hereinbefore described and which cover includes means connected therewith for holding said pair or pairs together and for carrying them as a unit.

It should be noted that the upper ends of rectangular cartons of the type herein described, are crimped around their edges providing undersurfaces along their marginal portions. Each such surface is straight along each of the four edges of the upper end of each carton, and one or more. of these surfaces is engaged by the carrier of this invention for lifting a pair of said cartons as a unit by a handle connected with the surface engaging member or members.

One of the objects of this invention is the provision of means adapted to engage at. least one of said surfaces on each. carton of each pair along substantially the full length of such surface inasmuch as such engagement not only prevents accidental tipping of the cartons relative to each other but also provides greater strength in the carton lifting structure where the strain is substantial and the structure must be formed to resist any tendency to distort the member that is adapted to engage said surface.

Other objects and advantages will. appear in the description and in the drawings.

Fig. 6 is a vertical sectional view taken through a cap or cover for a single carton, the upper end of said carton being shown in elevation.

Fig. 7 is a bottom plan view of the cover of Fig. 6.

In detail, referring to the cover and carrier of Figs. 1, 2, the cover portion comprises a flat, rectangular, horizontally disposed and horizontally elongated top 1 having end flanges 2, 3 and side flanges 4, 5 depending fromthe edges thereof. These flanges are integral extensions of the top 1 and flaps or tabs 6 integral with the side walls at their ends may connect the adjacent pairs of flanges at their adjacent ends. Obviously said tab 6 can be integral with either the side walls or end walls as desired.

Centrally between the ends 4, 5 the top 1 is transversely slotted as at 7 (Fig. 2). Slot 7 preferably extends substantially fully across said top 1 between side walls 2, 3.

A central carrier element in the form of a generally rectangular blank 10 of the same width as the length of slot 7 extends through the. latter, the upper end of said blank being formed with an opening 11 (Fig. 3) to provide a cross piece forming a handle 12 for grasping by the hand of a person with the fingers extending through opening 11. p

The marginal portion along the lower edge of opening 11 may be slit vertically at the ends and center of said opening to provide a pair of ears 13, 14 (Figs. 1, 2) adapted to extend oppositely outwardly of the blank in liopllacnar relationship at right angles to the plane of the lan These ears or tabs are glued or secured in any suitable manner to the underside of the top 1 along slot 7. These ears provide a stop to limit the upward movement of the handle 12 through said slot 7, and to uniformly position and correctly position the carton engaging portion of the structure that is on blank 10 below said ears.

The blank 10 extends downwardly below the top 1 to a point substantially even with the lower edges of the end and side flanges, as at 15, and a horizontally elongated strip 16 centrally folded on itself along a medial line 18 longitudinally thereof receives the lower marginal portion of the part 15. Portion 15 extends between the opposed sides of said strip to the said medial line along which said strip is folded.

The said strip 16 is formed with folding creases longitudinally thereof along lines 20 that are at the same level and the portions 21, 22 above said lines 20 extend divergently outwardly (Fig. 2) terminating in free, parallel, horizontally extending edges 24 spaced below top 1.

The width of the cover, or distance between side flanges 2, 3 is substantially equal to the distance between two of the opposite edges of the square top 25 of a carton 26.

Carton 26. is conventional, the square top 25 being crimped along its edges to provide an undersurface 27 along the marginal portion of each edge. The sides of the carton taper downwardly and outwardly from the innermost portions of said undersurfaces.

The length of the cover 1 is slightly greater than double the width of each. carton.

When the cartons are filled with milk, their sides will bulge outwardly slightly. Each edge of the top of the carton is vertically coplanar with the side wall therebelow. when the carton is empty, but when the cartons are: filled with milk, their sides will bulge out slightly, and when two filled cartons are placed together in side by side relationship, there will be a crack between the adjacent edges of their tops.

It is in this crack that the blade-like lower portion of the blank. 10 (and strip 16 below folding creases 18) is adapted to enter when the cover is placed over a pair of cartons 26? that are in side by side relationship. Upon moving the cover downwardly over such pair of. cartons, the portions 21 22 on blank 10 will slide past the adjacent edges of the tops 25 of said cartons until they clear said edges, and. then, being resilient, they will snap outwardly to the position seen in. Fig. 2 in which the free upper edges 24 of portions 21, 22 of said strips engage the under surfaces of the tops 25 along their adjacent edges.

The side portions 28 of blank defining the lateral sides of opening 11 are preferably formed with longitudinally aligned folding creases even with the upper surface of top 1 so that the handle may fold fiat on top of cover 1 to position 29 (Fig. 2). Thereby facilitating the packaging of a supply of the tops for storage or shipment.

From the foregoing structure, it will be seen that the free upper edges 24 of portions 21, 22 will move outwardly to securely engage tops 25 along the undersurfaces 27 where the latter join the sides of the cartons when the handle 12 is lifted to lift the cartons. Also portions 21, 22 will tend to move the upper ends of the cartons apart, but the opposite end flanges 2, 3 will prevent this. The greater the lifting force the tighter the cartons will be held.

In some instances it has been found desirable to extend the end flanges 2, 3 to provide extensions 30, 31 that are folded inwardly against the opposed surfaces of said flanges. Each of these extensions is formed with a folding crease 32 to provide free inwardly and convergently upwardly extending marginal portions 33, 34 that have free upper edges 35 adapted to engage the undersurfaces of the marginal portions of the carton tops 25 where the cover is slipped downwardly over a pair of cartons. These extensions are not absolutely necessary where only a pair of quart size cartons, or smaller, are being carried, but are desirable in the event more than a pairare being car riecli or if larger cartons then the quart size were to be use These portions 33, 34 function, together with the portions 21. 22 to lock the two opposite edges of each carton to the cover.

In certain installations, it has been found desirable to have the two opposed end flanges slanted oppositely outwardly and downwardly from the cover. In Fig. 4, said end flanges are indicated at 40, 41, and the extensions 42 thereon that correspond to extensions 30, 31 are inclined similar to said flanges. If desired, the side walls that correspond with side walls 2, 3 may also be inclined outwardl and downwardly.

In this form of the invention, the iunctures between the flanges and top are positioned so that the tops 25 of the cartons will fit within the cover the same as where the flanges are strai ht when the covers are moved downwardly a ainst said to s. But the lower edges of the flan es Will be more widely spaced from each other than in the form shown in Figs. 1, 2. By this structure the covers are more readily and easily positioned on the cartons where the cartons may not be as uniformly spaced apart as would be required for the cover of Figs. 1. 2.

In positioning the covers on the cartons manually, it has been found that by engaging one of the pair of cartons with one of the flanges 4, 5 while the other flange is elevated, and then swinging the other flan e downwardly with the blade-like strip 16 entering the space between the pair of cartons, the c ver may be quickly positioned and locked onto a pair of cartons.

To remove the cover from the cartons, it is only necessary to swing the lower ends of the pair of cartons apart and the cover will become detached from its locking position on their upper ends.

Except for the differences above mentioned between the covers of Fig. 2 and Fig. 4, they are the same. It may be pointed out that it is not always necessary with the invention of Fig. 4 to have the side flanges slanted outwardly. In machine capping, this is desirable however inasmuch as the tops will automatically correctly position the tops of adjacent cartons should they be slightly out of proper alignment or spacing.

Where four cartons are to be carried, substantially the same structure is used as in Figs. 1 to 3 except that the top 42 is substantially square and the central carton engaging member 43 is double the width of blank 10. The end walls 44 are twice the length of end walls 4, 5 and the side walls 45 are provided with marginal portions 46 on extensions that have the same structure as extensions 30, 31. The marginal portions 46 correspond in structure and function with the marginal portions 33, 34 on ends 2, 3, except that they are on side walls 45.

It will be seen that the cover of Fig. 5 will extend over four cartons, there being a pair along each side of the central member 43, instead of only one. Also three of the undersurfaces along the marginal portions of the tops of each carton will be engaged by the carrier, instead of only two. This will insure against any of the four cartons accidentally slipping from the carrier.

In Figs. 6, 7 a single cover is shown for a single carton. This cover 47 is perfectly square with a depending flange 48 along each edge, and an extension 49 is on each flange doubled against it on the inner side in exactly the same manner as extensions 30, 31 in Fig. 2. Each extension includes a resilient marginal portion 50 having a free upper edge 51 adapted to engage the undersurface of each marginal portion 52 of the carton.

The cover for each carton is easily and quickly slipped over the top of the carton and may be easily torn therefrom.

It is pertinent to note that where the carrier structure is employed it is highly desirable that the edges 24 of the marginal portions 21, 22 engage the undersurfaces of the adjacent portions of tops 25 of the cartons 26 substantially from end to end thereof.

It is to be noted that with the present structure practically the entire load or weight of the cartons is taken by the handle and not by the cover. The cover keeps the tops of the cartons clean and holds the cartons together.

The fact that the lifting of the cartons is done from their upper ends avoids the necessity for a base under the cartons. The avoidance of such base is desirable both from the standpoint of economy of material and to eliminate the possibility of the carrier becoming wet and weakened.
