2 Claims.

This invention relates to cartons of fibre board, paper board or the like for use in shipping comparatively heavy, boat-shaped objects.

Heretofore it has not been considered practical or possible to ship an object as large or as heavy as a ten or twenty foot outboard motorboat in a carton made entirely of paper board. Usually, boats, bathtubs, etc., have been shipped enclosed in a wooden crate or in a cardboard carton which contains an interior wooden crate structure as a reinforcement.

Disadvantages of enclosing an article to be shipped in a Wooden structure are that the structure usually cannot be shipped or stored in knock-down condition, the assembly of the crate requires wood-working tools, installation time and factory space, the crating structure is heavy and adds to the freighting charges and the outside dimensions of the packaged article are increased because of the wooden framework.

I have discovered that such articles can be shipped safely and securely in a carton made entirely of paper board, if constructed according to my invention, without the use of any interior or exterior wood frame reinforcement. I provide a carton in the form of a six-walled rectangular container, preferably of double walled corrugated paper board and provide integral flanges on each free edge of the walls, which are turned inward, to strengthen the carton. To position and cushion the boat-shaped article within the container, I provide substantially wedgeshaped fillers preferably of similar double-walled,

CII

corrugated paper board and located at each end of the container.

The cooperative action of my new fillers with the walls and corners of the container not only retains the article in position, but prevents rupture of the container by cushioning any movement of the article in the container, prevents crushing of the container when stacked, by distributing the load, and eliminates the need for pads, etc., to protect the surface of the article from damage.

My container and llers are creased and cut into at blanks of paper board and can be shipped or stored nat until needed. The filler blanks are preferably creased transverse to the corrugations of the board to provide more yieldability without loss of strength. Large numbers of my container and fillerblanks can be stored in a boat factory in a small space whereas a large space is required to store the equipment and material necessary to make wood crates or wood reinforcements for cardboard cartons.

The container of my new carton is assembled by staying the edges of the cover walls and unfolding the tubular body of the same in a well known manner and the fillers are simply folded into substantial wedge shape on their crease lines and inserted between the bow and stern of the boat and the ends of the container. When assembled and packed, the tare weight of my new carton is only about one-tenth that of conventional boat crates or cartons, thus providing a large reduction in shipping cost. Similarly, the outside Vdimensions of my carton, since there is no wood reinforcing structure Within, is less than the conventional type, thus giving rise to a saving of space and in cost of shipping.

Upon arrival at a factory outlet, the covers of my carton can be removed, and, if desired, the tubular body of the container can be stored flat, while the article contained therein is displayed.

Upon reshpping to a purchaser, the same covers and container may be reinstalled. This is in contradistinction to a boat shipped in a wooden crate Where the crate must be removed and usually damaged before the article can be displayed. Ordinarily the parts of such a crate cannot be used again due to damage or loss.

My carton may be used for shipping scows with blunt ends, sailboats with abbreviated keels, motor boats with a rounded bow and a blunt stern, canoes with pointed ends, or, in fact, any generally boat-shaped article. My

Vfillers can be adapted to the particular shape of either bow or stern and in each case have a double thickness of material in contact with the boat, backed up by an air space into which the doubled material can yield. In the case of broad beamed boats, I prefer to removably mount two transverse Wooden cleats across the gunwales and to bind the outside of the carton with steel strapping at the cleats so that the carton may be lifted by a crane or the like without losing its rigid rectangular shape.

The principal object of my invention is therefore'to provide a shipping carton of corrugated paper board or the like with end lillers of similar material in which a heavy boat-shaped article may be shipped without the necessity of an interior framework of reinforcing material.

Another object of my invention is to provide end llers of corrugated paper board so folded as to form an air space into which the ller panel under rupture pressure may yield and so folded as to transfer crushing and rupture pressures to the walls and corners of the container, v

A further object of my invention is to provide 3 a container and fillers for the same, all of which can be shipped or stored in knock-down condition and can be assembled for use without mechanical equipmentl or expert knowledge.

Other objects of the invention have been outlined above and will appear in the following description:

Fig.v 10- is a pla-nviewin section on line i-ill of the carton shown in Fig. 9.

As shownin Figs. 1 tod, the preferred form of my new carton is capable rof carrying a boat- `shaped article of substantial size and weight such as the Voutboard motor boat O. My carton has been used successfully4 to ship-outboard boats of over fifteen feet inlength and 4centreboard sailboatsV each weighing between three and four hundred pounds and made of material such as plastic impregenated Fibreglass It may also be usedl for boat-shapedarti'cles of other materials such as aluminum or Wood.

The containerA, ofmy newcarton, has four side walls W,- H, t2, and t3, atopV Wall- !4 and a bottom wall l-5, thus forming a six walled-rectangular-box. The side walls'aresuitably creased, cut or stayed at'the corners I6, H, i8, and la, in

`a well.. known manner, incr-der that the four walls 10i, Il, l2and=-|3 of tubular body 20 of Ycontainer A- may be shippedI or stored -flat and unfolded when needed-.l I provide integral inturned edge flanges 2lonl-theupper edge of each side wallandintegral-.edge anges 22 on the lower edge. of -each-.wall of tov add strength to the conta-inerwhenused' for aboat-shapedI article of comparatively broad beam such as O. I also provideintegral intu-rned edge flanges 23 on top wall i4; and integral inturned edge flanges,l 24 on bottorn wall-.l 5.. which overlie-the side walls andV also add strength. to the container A.

The material from. which the container and fllersof mynew carton are made` is what I call double walled corrugated paper board- The doublewallpreferably consists of A and C flute. 100% Kraft. 0.023. outer-middle-inner liners with 0.009l Kraft corrugating medium. The crease lines, uponwhich. the walls, flanges and panels are folded to forma fibrous hinge, indent only the inner liner and; the creases Vare transverse to the corrugations in the corrugating medium. Rupture and crushing, pressure or impacts are thus passed along theV corrugations toA other parts of the carton rather than causing the paper board to break along a corrugation.

In generalxthe. llers provided inV my new carton comprisev a striptofdouble walledA corrugated paper boarld creased transversely to the corrugad tions and oent through interior angles, one of which is ag'. right angle, into iive panels with at least two vpanels overlying other panels. The folded fillei` thus is generally wedge shaped with at least twd adjacent panels forming a right angle to nt an iriterior corner of the rectangular container and "at least two overlying panels arranged to Contact the portion of the boat-shaped article that it is desired to retain in position and cushion against movement. In al1 of my llers, whether right triangular or trapezoidal in cross section, the panels are so folded as to define an air space thus providing roomrfor the two overlying contactpanelsto yield and bend under stress. When yielding, the impact upon the contact panels is passed ialong by the corrugations to other panels of the filler and thence to the walls and corner flanges of the container where it is absorbed and whence the contact panels are caused to rebounddue to the. inherent resiliency of, the .corrugated material.

In the preferredform of my. carton,l Iusean end llerV C atI the. stern 30` of 0 and a pairA of corner llersD at. the rounded. bow..3 l' of O1.

As shown in dotted lines in Fig. 2, such movement of the boat O causes the contact point 60 to bend the diagonal 6| of the primary right triangle 65, and to bend diagonal 59 of'the larger secondary right triangle -66 of the pair of secondary right triangles 66 and 61 contained in 65, into the air space 68 of 66. After yielding into space 68, diagonals 6| and 59 rebound into their normal retaining position, having absorbed the impacts and transferred such impacts to other panels of strip D and to the adjacent walls of container A.

Sidewise movement of the boat O also causes contact point 60 to bend 6| and 59 into 68 and the impact is passed along to the adjacent side wall l of container A and absorbed thereby.

For convenience in hoisting my new carton by a crane for loading, unloading, and stacking, I provide two or more transverse cleats 80, 8|, of wood or the like, which extend transversely of the container, intermediate thereof, on opposite sides of the centre of gravity. Cleats 80, 8| rest on the gunwales 82 of OI and are provided with holes 83 at each end, arranged to register with the oar lock holes 84 of boat O and to be removably connected thereto by bolts 85 or other suitable means. On the exterior of the container I provide metal girth straps 86, 81, drawn taut in a well known manner and located opposite each cleat and may also provide a longitudinal girth strap 88 for additional reinforcement, as shown in Fig. 3. The ends of each cleat 80, 8| abut on each side wall such as l0 or I2 of A and thus are useful in maintaining the rigidity of the carton.

In Figs. '1 and 8, I show a modification of my device for use with a canoe M or similar boatshaped article having both ends rounded or pointed. The container F is six Walled having an open tubular body with four hinged side walls |0|, |02, |03, and |04, and closure walls at each end and |06. For reasons of economy and ease of manufacture, I lind that boat-shaped articles of knarrow beam are best enclosed in an elongated horizontal tube such as F, rather than a low walled vertical tube such as 20, although either can be used.

I prefer to use a pair of corner illlers such as D at each end of container F as shown at the bow |01 of M. However, I may use a corner filler such as G as shown at the stern |08 of M, which comprises a strip 99 of double walled corrugated paper board bent into wedge or right triangular shape. As indicated, G is bent at crease lines which are transverse to the corrugations through three interior angles ||3, ||4 and ||5, ||5 being a right angle, to form five panels |09, ||0, ||2 and 3|0 with panel |09 overlying the hypotenuse or diagonal panel ||2 and panel 3|0 overlying panel ||0. Panels 310 and rest against walls |05 and |02 of F and the width of the strip 99 is equal to the distance between walls |0| and |03 of F to make a snug corner t. An air space ||6 is defined by the i'lve panels of G and provides rooml for panels l2 and |09 to bend and yield under pressure or impact from a single contact point such as ||1 on stern |08 of M. Space is also provided at ||9 and |20 between the tip of stern |08 and wall |05 and the tip of bow |01 and wall |06 to enable M to move without rupturing container F. It is obvious that all four corner llers would ordinarily be of the same type and I find the type shown at D to be preferable to the type shown at G.

- for a boat shaped article N with blunt ends and broad beams such'as a dinghy, scow or the like. The short vertical tubular body 2|0 of container L has four side walls 204, 205, 206, 201, an upper wall 209 and a lower wall 208, each wall being provided with inturned ilanges for strengthening purposes. End llers H, similar to C, are used between the bow 3|2 and wall 205 and between the stern 2| and wall 201. Two or more transverse cleats 2 I3, removably attached to the gunwales 2|4 of N, by bolts 2|6 and a girth strap 2|5 are also used in the manner and for the purpose abovel described.

As in end ller C above, an air space 220 is provided in I-I into which two overlying diagonal panels such as 22|, 222, of H may yield to absorb impact and pass the impact along to other panels and walls of the container.

It should be noted that all of my llers whether trapezoidal as in C and H, right triangular as in G, or right triangular with inner right triangles as in D are characterized by the following features. Each is formed from a blank of double walled corrugated paper board which is creased transversely of the corrugations and bent at the creases into a substantial wedge shape. Each has at least five panels, with the oblique or diagonal surface, presented to the boat-shaped article, having two overlying panels which are free to slide upon each other and arranged to yield and bend into an air space dened by the ve panels. Each also has at least two other panels which overlie and form a web of double thickness between the oblique or diagonal surface and a corner of the container. The oblique panels of double thickness are thus reinforced by a web of double thickness which in turn is reinforced by the corner of the container at which the flanges of the tubular body and/or closure members are located.

I claim:

l. A corner ller to cushion the rounded end of a boat-shaped article from movement in a rectangular container, said ller comprising an elongated strip of corrugated paper board or the like, bent at spaced transverse lines into a plurality of brous hinged panels which define a primary right triangular air space divided into two secondary right triangles, each of the opposite end panels of the -strip overlying a portion of the hy. potenuse panel of the primary triangle to present. an hypotenuse panel of double thickness of paperboard, each hypotenuse panel of the secondary triangle being positioned at right angles to each other and the intermediate panels of each sec` ondary triangle meeting to form a central web of double thickness extending perpendicularly from the hypotenuse of the primary triangle to the right angular corner of said filler.

2. A filler, for use in the interior of rectangular cartons, said iiller comprising a continuous elongated strip of corrugated paperboard material bent transversely of its corrugations to form an hollow enclosed figure, said figure having two walls of a single thickness of said material, each positioned at right angles to the other; having a third wall positioned obliquely to said right angularly positioned walls; having all of its walls, except said two right angularly positioned walls Z formed of a; double'tliicknees dit said: materie-I. and having' a; Web` of' a1. dciuble thickness of said ma;- terial, extending from; ani intermedi'ete linel on said oblique Wall to the meeting linefof' seid right angular-1y positioned-f Vitalis.
