Nilles [5 7] ABSTRACT A package including a base formed from a corrugated sheet having end walls at each end and dividers at equally spaced intervals intermediate the end walls for separating rows of riser liners from each other, a cover formed from a corrugated sheet having end walls at each end and dividers at equally spaced intervals intermediate the end walls for separating rows of riser liners from each other, the cover being mounted on the riser liners transverse to the base to isolate each riser liner from each other, and a thin film of heat shrinkable material completely enclosing said cover and base and being heat shrunk into tight engagement with the cover and base to hold the liners in fixed position in the package.
10 Claims, 4 Drawing Figures 10/1968 Canada ..229/23 AB PACKAGE FOR TRANSPORTING AND STORING LINERS FOR FOUNDRY RISERS BACKGROUND OF THE INVENTION Heat insulating liners and exothermic liners which are used to line the risers in foundry castings are generally manufactured at points remote from the place of use. Storage and transportation of the liners is therefore required before the liners are actually used. These liners are made from granular refractory materials and exothermic materials and are bonded by a binder. These materials are known to be hydroscopic and must be stored in a dry place. The liners are also subject to breakage on impact. If adjacent liners are allowed to rub together during transport, the surface of the adjacent liners will wear away due to the abrasive nature of the materials used to form the liner.
SUMMARY OF THE INVENTION The package of the present invention has been developed to hold the liners in fixed positions, isolated from each other, completely cushioned and protected from the moisture in the atmosphere. The package includes two identical corrugated sheets which have been partially cut for bending to form end walls at each end of the sheet and intermediate dividers at equally spaced intervals between the end walls. One of the corrugated sheets is used to form the base or bottom for the package and separates the liners into rows of equal numbers of liners. The other corrugated sheet is used to form the cover for the package and is placed on the top of the liners transverse to the base with the dividers separating each liner in each row from the adjacent liners in the corresponding row. Generally nine liners are stored in a package, although additional liners can be included as long as the symmetry is maintained between the number of liners in each row and the number of rows of liners. The cover and base are then completely enclosed in a thin, pliable heat shrinkable material which is heat shrunk into tight engagement with the cover and the base. The liners are then held in a fixed position within the package. This arrangement of the cover and base assures that each liner is spaced from each adjacent liner by a double thickness of corrugated material and is held in a fixed position in the package. The corrugated sheet provides a cushion from shock for transportation. The heat shrinkable material provides a moisture barrier for storage.
Other advantages will become apparent from the following detailed description when read in connection with the accompanying drawings.
THE DRAWINGS FIG. 1 is a perspective view of the package of this invention with a corner broken away to show one of the liners in the package;
FIG. 2 is a plan view of one of the corrugated sheets used to form the cover or the base for the package;
FIG. 3 is an end view of the corrugated sheet of FIG. 2 folded to form the bottom or base for the package;
FIG. 4 is an enlarged view of a portion of one end of one of the dividers showing the sheet partially folded.
DESCRIPTION OF THE INVENTION The package 10 as seen in FIG. 1 generally includes a base or bottom sheet 12, and a cover or top sheet 14. A number of tubular liners or sleeves 16 of substantially equal outer diameter and height are positioned on the base with the same number of rows of liners 16 as there are liners in each row. In the embodiment shown in FIG. 1 the package contains three rows of liners with three liners in each row. The cover 14 is placed on the top of the liners 16 transverse to the bottom 12. A heat shrinkable plastic material 18 is wrapped around the base and cover to completely enclose the liners 16. The plastic material 18 is heat shrunk into tight engagement with the cover 14 and the base 12 to hold the'liners 16 in a fixed position in the package.
In accordance with the invention, the base 12 and cover 14 are each formed from an identical corrugated sheet 20 as seen in FIGS. 2 and 3. The sheet is partially out along lines 22, 24, 34 and 36 on one side and along lines 38 on the other side. The ends of the sheet are folded along lines 22 and 24 to form end walls 26 and 28 at each end of the sheet 20. The end walls 26 and 28 are shown as having a height equal to the height of the liners 16 however, the end walls can be shorterwhere protection of the liners is not considered necessary at the ends. The corrugated sheet 20 can take the form of a corrugated paper or cardboard.
Means are provided in the sheet 20 between the end walls 26 and 28 to form separate rows for the liners 16. Such means is in the form of a pair of dividers 30 and 32, each divider being formed by folding the sheets along lines 34 and 36 on one side and line 38 on the other side of the sheet. The sheet when folded as seen in FIGS. 3 and 4 has three separate rows separated by a double wall of corrugated material that acts as a cushion between the liners 16. The dividers 30 and 32 are parallel to each other and to the end walls 24 and 26 and are spaced at distances from each other and from the end walls equal to the diameter of the liners.
The cover 14 and the base 12 are identical and are arranged in a transverse relation so that the dividers 30b and 32b on the base and the dividers 30a and 32a on the cover are perpendicular to each other. The dividers on the base separate the liners into rows and the dividers on the cover separate the liners in each row from each other.
The liners 16 are held in a tight fixed position between the cover 14 and base 12 by means of a film of heat shrinkable plastic material I8. This material is well known and can be formed from either polyethylene or polyvinyl chloride. A single layer of eight mil or less thickness has been found adequate to provide sufficient strength to hold the liners fixed during transport. This material also provides a moisture barrier around the liners for storage. The package after being wrapped in the heat shrinkable material is passed through an oven to shrink the material into tight engagement with the cover 14 and base 12.
