7 Claims. (Cl. 294-872) This invention relates to improvements in carriers or handles for chime-end cans and similarly shaped receptacles characterized by a rim, head, or projection at at least one end having a diameter slightly larger than the body of the receptacle.

I The most commonly used form of receptacle is the chime-end tin can. Cans of a capacity exceeding 1000 cc. are widely used for foods, beverages, oil, grease, paint and other products. They are'somewhat awkward to handle because of their weight and their diameter which is of the order of four inches and often larger. Cans containing heavy merchandise, suchas lead paint, are particularly inconvenient to handle unless equipped with a bail which increases the cost of the can considerably.

Similar considerations apply to jars of comparable size, except that jars are even heavier than tin cans becauseof the added weight of the glass.

The present invention provides a handle of foldable sheet material, preferably paperboard, which can be attached to a chime-end can or a similarly shaped receptacle and which holds the receptacle securely without the use of adhesive or supplementary fastening means between the handle or carrier and the receptacle to which it is applied.

Basically, handles or carriers incorporating the present invention comprise a top or handle panel by which the device is grasped and carried. Downwardly extending side walls are articulated to the top panel, and straps extend from the side walls for peripherally engaging the receptacle immediately below the chime-end or comparable projection.

The handle or carrier may be prefabricated in the form of a preglued flat collapsed blank'structure and is readily prepared for attachment to a receptacle by a simple folding operation preparatory to slipping the straps over the end' of the receptacle.

In the design and construction of a handle or carrier of the aforementioned type a problem is encountered by reason of the fact that the straps must encircle the body of the receptacle snugly, yet permit the larger chime-end or similar portion of the receptacle to be inserted between the straps.

Since paperboard is not elastic, and since it is not practicable to apply the straps around the receptacle body and then glue the straps to obtain an enclosure of a diameter less than the chime-end, it is manifestly not a simple matter to obtain a fit between handle and receptacle snug enough to prevent the receptacle from slipping out of the handle or carrier. 1

The present invention solves this problem by providing a construction in which the mouth of the circumferential strap assembly may be distended temporarily for easy insertion of the end of the receptacle, but is automatically reduced in, diameter by insertion of the receptacle, whereafter the mouth cannot be enlarged again.

As will be seen from the following description a tiltable hinge panel is incorporated in the handle or carrier structure which, upon tilting, permits the mouth of the strap assembly to be distended to a diameter considerably larger than the diameter of the largest portion of the receptacle. Subsequent elimination of the tilt of the hinge panel, which takes place automatically by reason of insertion of the receptacle, causes the straps to be drawn tight about the circumference of the receptacle, thereby securely locking the receptacle in the carrier so that the receptacle portion of largest diameter, for example, the can-chim-e, cannot be withdrawn.

The gripping action of the straps is preferably supplemented by an arrangement in which the application of the lifting force at the handle or top panel automatically pulls the straps the tighter, the greater the lifting force. At the same time the lifting force exerted at the handle is so distributed that there is no danger of tearing of the board at any of the cuts or fold lines incorporated in the construction.

These and various other structural details, features, and advantages of this invention will appear more fully from the detailed description which follows accompanied by drawings showing, for the purpose of illustration, a preferred embodiment of the invention. The invention also resides in certain new and original features of construction and combination of elements hereinafter set forth and claimed.

Although the characteristic features of this invention which are believed to be novel will be particularly pointed out in the claims appended hereto, the invention itself, its objects andadvantages, and the manner in which it may be'carried out, may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part of it, in which:

In the followingdescription and in the claims various details will be identified by specific names for conveni: ence. The names, however, are intended to be generic in their application. Corresponding reference characters refer to corresponding' parts in the several figures of the drawings. I p I The drawings accompanying, and forming part of, this specification. disclose certainlspeci fic details of the invention for the purpose of explanation of broader aspects of, the. invention, but it is understood that the deails may' be modified in various respects without departure from the principles of the invention and that the inventionmay be applied tdother structures tha'n the one shown. j V Y M The blankA of Figure '1 consists of foldable sheet material, such as paperboard, and may be cut andscored in multiple from rolls or sheets of board on conventional cutting and creasing machines. 'i The blank comprises a top panel 11 which may be recessed along its side edges 12 and 13 to provide a other along fold lines of which fold line 18 may be termed a top fold line, 19 and 20 main fold lines, and 21 a further top fold line.

A central cut 22 extends the length of the main panel 15 and extends beyond the top fold lines 19 and 20 into the body of the side walls 14 and 16. The central cut 22 terminates at transverse side cuts 23 and 24 in the side walls 14 and 16, respectively.

The side walls are further traversed by intermediate folding scores 25 and 26. These intermediate folding scores are parallel to the top and main fold lines and determine the location of the transverse side cuts 23 and 24 which extend between apex points 27 and 28 and between apex points 29 and 30. These apex points may be considered the ends of the folding scores 25 and 26 and also the ends of the transverse cuts 23 and 24. The cuts 23 and 24 may be straight, but are preferably of arcuate shape, bowed towards the top fold lines 18 and 21 for reasons which will appear later.

The apex points lie closer to the central cut 22 than to the top fold lines 18 and 21, the difierence in the distances being at least one-sixteenth of an inch, and preferably of the order of an eighth of an inch. At any rate, the difference in the two distances should be at least equal to the axial dimension of the chime of the can tobe held in the carrier or handle. The drawing shows that a representing the distance of the apex points from the central cut 22, is less than b representing the distance of the apex points from the top fold line.

Diagonal scores 31, 32', 33 and 34 extend from the apex points 27, 28, 29 and 30 towards the main fold lines 19 and 20, the angle of the diagonal scores with respect to the intermediate folding score being 45 degrees.

The respective intermediate folding scores 25 and 26 and the diagonal scores define substantially triangular panels 35, 36, 37 and 38.

The central cut 22 divides the main panel into two straps 39 and 40, and each strap may be subdivided into a plurality of strap panels by transverse scores 41, 42 and 43. In the illustrated embodiment there are four strap panels resulting, as will later be seen, in an enclosure representing a twelve-sided polygon.

The blank A of Figure 1 may be converted into a carrier or handle structure as follows:

Adhesive a is first applied to the underside of the glue lap 17 and the glue lap and the side wall 16 are then folded about the fold line 20 to bring the side wall 16 over the main panel 15. Substantially simultaneously, or shortly thereafter, the top panel is folded about the top fold line 18 to bring its end portion into adhesive engagement with the coated surface of the glue lap 17.

A flat collapsed tubular structure A results. The tubular blank A may be shipped and stored in flat condition and may quickly be converted into a handle or carrier structure for attachment to a chime-end can without further gluing operations. This is done as follows:

, The tubular blank structure A is first squared as shown in Figure 3. Next, the two straps 39 and 40 are folded about their respective diagonal fold lines 31, 32, 33 and 34. The resulting structure A" is shown in Figure 4. The straps 39 and 40 are articulated to the side walls 14 and 16 by the triangular hinge panels 35, 36, 37 and 38. These hinge panels are unique in permitting the mouth of the handle or carrier structure to be distended. The mouth is represented by the edges 44 and 45 which previously were the side edges of the blank. There are two principal ways in which the enlargement of the mouth may be accomplished.

. Referring first to Figure 5, the straps 39 and 40 may be swung downwardly, as indicated in broken lines. The pivots of this displacement are the apex points 29 and 30. It is quite evident that the distance between the edges 44 and 45 is greatly enlarged so as to permit insertion of a can without danger of striking the edges 44 and 45.

A further way of enlarging the mouth is illustrated in Figure 6. It involves basically an outward slanting of the lower portions of the side walls 14 and 16, accompanied by an inward slanting of the hinge panels 35, 36, 37 and 33. As a result the distance between the cut edges 23 and 24 is enlarged.

Referring now to Figure 4 it is readily seen that an enlargement of the diameter in the direction of the line 5-5 and an enlargement of the diameter in the direction of the line 66 permits a cylindrical object, such as a chime-end can, to be inserted without difliculty. It is also readily seen that if the cylindrical object, such as the can-chime, strikes the lower portion of the straps 39 and 40 adjacent the edge 22, it tends to right the structure towards the position shown in solid lines in Figure 5. This action occurs because the engagement with the straps 39 and 40 is at a point below the apex points 29 and which act as pivots. The righting-of the straps 39 and 40 automatically causes the straps to tighten about the inserted article.

The triangular shape of the hinge panels 35, 36, 37 and 38 assists in the tightening in a unique way. It is readily apparent from Figures 4 and 6 that the points 46, 48 and 47, 49 may be brought closer together by increasing the slant of the triangular panels 35, 36, 37 and 38. Conversely, the points 46, 48 and 47, 49 are moved apart by reducing or eliminating the slant of the triangular panels. The slant of the panels is automatically reduced by the righting of the straps 39 and 40. This unique action is the result of the triangular shape of the hinge panels whose pivot points are the apexes 27, 28', 29 and 30, but whose opposite sides have a horizontal projection which is large for great slope and small for small slope angles and zero if the hinge panels are vertical. By the same action righting of the straps 39 and 40 tends to draw the side walls 14 and 16 together.

In the drawings a chime-end can 50 is shown to represent one form of cylindrical receptacle to which the handle structure may be attached. The can has a chime 51 of a diameter larger than the diameter of the can body. The diiference in diameter is of the order of 2 to 3 millimeters and the axial dimension of the chime is of the order of 2% millimeters, slightly more than onesixteenth of an inch and slightly less than one-eighth of 'an inch. The latter dimension determines the spacing of the engaging strap edge 22 from the top panel 11. It is evident, however, that other forms of receptacles having a similar projecting rim, for example, a jar with a top may be inserted and held in a similar manner.

A preferred manner of inserting the receptacle into the carrier structure is shown in Figure 7.

The can 50 is held at an angle and is inserted into the carrier structure until the chime 51 is seated at the fold 18 between the top handle panel 11 and the side wall 14. The can is then righted as indicated by the arrow 52 until the edge 22 snaps above the chime 51. During the final phase of the inserting motion the side walls 14 and 16 are righted, as previously described, with the result that the enclosing straps are drawn tightly clined position and the can may be inserted with the cylindrical can wall substantially parallel to the inclined strap 39 shown in broken lines.

The arcuate shape of the cuts 23 and 24 serves a multiple purpose. Referring first to Figure 7 it is evident that the portion of the chime immediately above the arrow 52 has additional clearance with respect to the edge 24 if the cut is arcuate instead of straight. The arcuate shape therefore facilitates insertion of the can. From Figure 5 it is further evident that the ends 53 and 54 of the straps are in closer proximity if the cut is arcuate than if it were straight. The arcuate shape of the cut, therefore, extends the length of the engaging edge 22 near the center of the side walls 14 and 16.

Figure 8 shows the can 5% in inserted position in which the edge 22 of the straps securely locks the can chime 51. The can is then inverted as shown in Figure 9, and may now be lifted up and carried by the top panel 11 which is shaped as a handle.

When lifted by the handle, the portions of the chime in line with the center line of the top panel 11 tend to bulge the side walls at the points 55 and 56. These bulges provide additional frictional engagement between the handle or carrier and the can itself. Also, the portions of the side walls 14 and 16 adjacent the top fold lines 18 and 21 are moved slightly beyond the vertical position with the result that the straps are drawn even tighter around the can. The frictional engagement at the bulges relieves the straps proper of a portion of the weight to be carried, thus reducing the danger of tearing of the board at the apex point.

It is evident that various modifications may be made in the basic structure. For example, shapes of the handle 11 may be altered, the number of sides of the polygon may be varied, and numerous other modifications be made without departing from the essence of the invention. For cans of a diameter of approximately four inches at IZ-sided polygon, as shown in the drawings, has proved advantageous. The number of sides determines the number of engagement points which may be varied according to the diameter of the can or the weight of its contents.

Instead of inserting a can into the handle structure as shown in Figures 5 to 8, the handle structure of Figure 4 may also be slipped over the top of an upright can without any difliculty. This may be the most convenient form of application involving all the distending and contracting actions previously described.

The carrier offers numerous advantages beyond its low cost. It covers and obscures little of the conventional can label, but provides additional space for descriptive or promotional matter not only along its peripheral portion but also at, the top of the can which normally does not carry descriptive matter. It is superior .to the conventional wire bail in that it permits closely placed cans to be easily picked up by the handle in distinction from the depending bail which is normally inaccessible between cans.
