No. 723,739 Int. Cl. B65d 85/00, /46, 13/00 US. Cl. 206-46 6 Claims ABSTRACT OF THE DISCLOSURE FIELD OF THE INVENTION This invention relates to shipper packages. In particular this invention relates to a shipper package for shipping a bath tub.

DESCRIPTION OF THE PRIOR ART Presently articles such as bath tubs are shipped in packages or containers which are made from wood or corrugated fibreboard or a combination thereof. The known packages are expensive to manufacture and considerable time is required in order to position the bath tub within the package. The known containers are not well suited for automatically or semiautomatically packaging bath tubs and consequently the packaging operation is a manual operation. Furthermore the known containers do not provide any specially adapted structure for supporting the portions of the bath tub best suited to bear the weight of the tub during its transportation. Additionally the known packages do no provide any support means formed integrally with the main structure of the package to provide padding for supporting and spacing the bath tub within the package.

The present invention relates to a shipper package which comprises a pair of end caps formed from a fibreboard or paperboard blank and adapted to receive an end of a bath tub in close fitting relationship. The package also includes a wrapper which extends around the portions of the bath tub which are not enclosed by the end caps.

The invention will be more clearly understood after reference to the following detailed specification read in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings it will be seen that the shipper package generally indicated by the reference numeral 10 comprises a pair of end caps 12 and a wrapper member 14. Each face of the package 10 is substantially rectangular such that several of the packages may be stacked one upon the other or side by side in uniform rows. The rectangular shape of the package is much more convenient for storage purposes than the normal outline of a bath tub which would not permit the bath tub to sit squarely on a flat surface or permit one bath tub to be squarely supported by another bath tub one upon the other. By providing a pair of end caps of generally rectangular configuration the problems of storing and shipping bath tubs are considerably reduced without the need to provide a carton which is sufiiciently large to contain the entire bath tub and which must be provided with suitable spacer members to support various portions of the tub.

FIGURE 2 of the drawings illustrates the manner in which the present invention is used to package a bath tub such as that generally indicated by the reference numeral 16. The bath tub 16 is of the well known type which has a flat front facing or skirt 18 and upper edge portions 20, 21 and 22. The transverse edge portions have a lip 24 extending upwardly from the outer edge thereof and the longitudinal edge portion 22 has a similar lip 26 extending upwardly from the outer longitudinal edge thereof. End spacer pads 28 and back spacer pads 30 are formed with slots 29 and 31 to receive the lip portions 21 and 26 respectively in a close fitting relationship. The pads 28 and 30 are preferably formed from several sheets of corrugated paperboard or fibreboard laminated with one another to provide the required thickness. Pads 28 and 30 are of generally rectangular configuration and have an upper surface of substantially greater width than the width of the lips 24 and 26 and provides a greater surface area in contact with the end caps when the package is assembled; this serves to distribute the load carried by the upper surface of the package when the package is in use.

Referring now to FIGURE 3 it will be seen that the end caps 2 are formed from a paperboard blank which consists of an end wall panel 32 hingedly connected to composite side wall forming panels 34 and top and bottom Wall forming panels 36.

The side wall forming panels 34 are made up from panels 38, 40, 41 and 42 which are hingedly connected and foldable upon one another to form the side walls of the end cap. One panel 40 is notched as shown at 44 such that when the end cap is assembled a clearance space 44 will be provided to permit the marginal edges of the bath tub to extend into the space 44 to be supported by the edge 45 of the panel 40. The other panel 40 is formed with the lug 46 which upon assembly of the end cap extends parallel to the bottom wall 36 and provides a padded support for the lower end of the skirt 18 when the end caps are in use.

The panels 38 are formed with small projecting tabs 4S which upon assembly of the end cap fit into slots '50 formed along the fold line connecting side walls 36 to the end wall 32. When the end cap 32 is erected the tabs 48 enter the slots 50 and secure the end cap in the assembled position without any need for gluing or stapling. The panels 36a are hingedly connected to the side walls 36 and upon assembly of the end cap the panels 36a extend substantially at right angles to the panels 36 and are disposed between the panels 40 and 42 of the side walls 34.

The blank is reinforced by reinforcing tapes 52 which extend longitudinally of the blank and hand openings 54 formed in the end wall 32 between the reinforcing tapes 52. The entire assembled package including the bath tub can be lifted by the hand openings 54.

To assemble the end cap the panels 36a are folded to an angle of 90 relative to the panels 36. Panels 36 are then folded at an angle of 90 to the end wall 32 and the panels 42 are folded at an angle of 90 to the end wall 32. The panels 41 are folded at an angle of 90 to the panel 42 to form the inner face of the side walls of the end cap. With reference to FIGURE it will be seen that one of the panels 40 extends substantially parallel to adjacent panel 42 while the other panel 40 extends at an acute angle relative to the adjacent panel 42. As previously indicated the lugs 48 carried by the panels 38 enter the slots 50 to retain the end walls in their erected position.

In the packaging of a bath tube the pads 28 and 30 are positioned over the lips 24 and 26 of the top as previously described. The end caps are then pushed over the ends of the bath tub and tightly embrace the portions of the bath tub which they surround. The recess 44 of each end cap receives a corner portion of the edge members 20 and 22 and the edge 45 of the end caps provides a vertical support for these portions of the edge members 20 and 22. The lower corner portions of the skirt 18 are supported by the support pads 46 and the angularly disposed panel 40 extends into contact with the cup-shaped portion of the bath tub to limit the freedom of movement thereof.

After the end caps have been positioned the wrapper member 14 is applied as shown in FIGURE 1. The wrapper member 14 extends around the bath tub and the walls 34 and 36 of the end caps 12. The wrapper 14 is formed into a sleeve by a lap joint 15 and is retained in this sleeve configuration by means of an adhesive f staple supplied along the lap joint. The wrapper 14 is also stapled or otherwise adhesively secured to each of the end caps 14 to form an integral shipper package with a bath tub or the like located therein. It will be apparent that the packaging process is extremely simple with this type of package.

By providing end caps which can be easily assembled from a knock-down position the cost of the package is substantially reduced. Furthermore the wrapper material can be of a relatively lightweight paperboard or fibreboard material as the load in the moving and storing operations will be taken by the end caps which are preferably made from corrugated paperboard or fibreboard.

The bath tub which is illustrated in FIGURE 9 is of the well known type which is wider in the middle of its length than it is at either end by an amount W. In order to maintain the rectangular configuration while employing end caps of the type previously described it is necessary to make the exterior width of the end caps at least equal to the maximum width of the bath tub. If the end caps previously described with reference to FIGURES 3, 4 and 5 were used they could not have a close fitting relationship with the ends of the bath tub while forming a generally rectangular package.

A blank capable of providing an end cap for use with the type of bath tub illustrated in FIGURE 9 is shown in FIGURE 6. The blank is substantially the same as that illustrated in FIGURE 3 except that the panel 41 is wider than the corresponding panel illustrated in FIG- URE 3. Panel 41 is of a width W substantially equal to the distance in width between the maximum and minimum widths of the bath tub of FIGURE 9. The panel 36a is slit at 37 and formed with a fold line 39. The portion of the panel 36a bound by the fold line 39 and the slit 37 generally indicated by the reference numeral 35 is preferably crushed fiat to provide an edge suitable for receiving a spacer member 60. The spacer member 60 is formed from a plurality of layers of corrugated paperboard or the like in a manner similar to pads 28 and 30 and it is formed with a slot 62 into which the crushed edge 35 fits in a close fitting relationship. As shown in FIGURE 8 of the drawings the crushed edge 35 is folded along the fold line 39 to extend at right angles to the panel 36a and to support the spacer member 60 adjacent to the panel 41. When the end cap illus trated in FIGURE 7 is used in conjunction with the bath tub illustrated in FIGURE 9 the shipper package which is formed will be of a generally rectangular configuration.

From the above description of the preferred embodiments of the invention it will be apparent that the applicants shipper package is inexpensive to manufacture and may be assembled with ease.
