11. Mo., assignors to Presstite Engineering Company, St. Louis, Mo., 9. corporation of Missouri Application August 15, 1941, Serial No. 407,022 Claims. (01. 206-52) This invention relates to packaging means for putty-like materials which are made up in lengths. Among the several objects of the invention may be noted the provision of a package for lengths of putty-like materials, in which the desired elongate forms of the material are maintained without deleterious deformation until they come into the hands of users; the provision of a package' of the class described which may be roughly handled without deleteriously deforming its more or less fragile contents; the provision of a package of the class described which is easily made up and closed and equally easily opened and emptied; and the provision of such a package which is compact in form and economical in construction. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structures hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the United States patent application of William C. Ferguson, Serial No. 369,063, filed December 7, 1940, for Caulking compound, there is disclosed the idea of providing a continuous makdisclosed the idea of providing a continuous winding of a putty-like compound of preformed cross-section. The present invention constitutes an improvement upon the construction disclosed in said application.

section taken on line l-l The present invention has application to two forms of putty-like material. One form of material is shown in Figs. 1, 2, 6 and '7, and another form is shown in Figs. 3 and 5. Both forms are illustrated in a single container in Fig. 4.

Referring now more particularly to Figs. 1 and 2, there are shown at numerals i five parallel spirally wound lengths of a plastic caulking compound. Each length has a circular cross-section, and the five lengths lie upon a spirally wound separator sheet 3 which may be composed of paper suitably impregnated with a material which will prevent the caulking compound from unduly sticking; for example, oiled paper or the like.

'The winding is accomplished upon a short hollow arbor 5, preferably composed of cardboard or the like.

In Fig. 3: there is shown a winding on an arbor which is described in the United States Patent 2,256,864 of -Wil1iam C. Ferguson, dated September 23, 1941, for Sealing composition, consisting of a metal foil backing I on which is a ribbon or layer of putty-like caulking material 9. -This composite foil and caulking material is spirally wound on a hollow cardboard arbor 5 with a spirally wound paper separator ll.

After the lengths of material shown in Figs. 2 and 3 have been wound upon the respective arbors 5, in connection with their spirally wound separating sheets, there is applied to one side of each winding a square stiff sheet of cardboard l3. Each sheet of cardboard l3 has an opening l5 just large enough to frictionally and snugly engage the respectively hollow arbor 5. This frictional engagement prevents undue tilting of the sheet 13. Thus each sheet I3 is organized with an arbor 5.

After a number of rolls such as shown in Figs. 2 and/or 3 are produced, they are applied side by side over a spindle l1 having a cross-section formed as a hollow triangle, and preferably composed of corrugated board or the like. This spinmay be used. the object of such shapes being to obtain rigidity.

The supporting sheets l3 on the arbors 5 are still and of square form (Fig. 1), and when a group of these along with their loaded arbors 5 have been aligned on a spindle ll (say for example five of them), they may he slipped into a box I9 made of corrugated board or the like adapted snugly to receive said supports l3 edgewise. The assembly of spindle ll, arbors 5, supports I3 and side of the spiral. if desired.

within a disc-like box 21, without the use 2 the spiral winding of five rolls can be inserted into the box at one time as a unit. After these rolls have been inserted. the sheets i3 function as supports for the arbors S which in turn support the spiral rolls spaeedly from the box walls. They also function as separators between rolls. It is clear that the outline of each sheet is determined by the form of the box, being made snugly to fit. Other than square shapes may be used, if desired. The box has the usual side and bottom construction and openable top 2| which is shown open in Fig.4andclosedinFig. 1. 1

When a customer receives a box he needs only to open it in the usual way and withdraw its contents as a unit, consisting of the five rolls along with the spacers l3, arbors 5 and spindle II. If he wants to remove one of the spiral rolls, this may be simply done by slipping it with its arbor from the spindle l1 and replacing the remainder of the material in the box l9. This remainder will remain upright because of the aligning functions of the supports l3 and the spindle II.

If desired, the user wound material from on the strands of the type of material shown in Figs. 1' and 2 is thus handled, it is the separating paper 3 that takes the tension of the pull, since the material I is quite low in tensile strength. In this case, it will be seen that the withdrawal of a'given length of paper '3 supplies the user with five lengths of the putty-like material supported on the paper. Hence the total length of this material is five times as long as the length of the separator. The five lengths may then be removed from the paper for application to caulking uses. In the case of Fig. 7 the foil I also assumes tension resisting functions;

In Fig. 5 is shown how the tape-like material I, 9 may be wound upon an arbor 5 with the spiral paper separator and placed in a disc-like box 2| having a removable lid 23. Beneath the lid is inserted a round spacer 25, and a similar spacer, or a piece of paper, may be used on the other the box, simply by pulling In Figs. 6 and '7 is shown how a coil of the multi-wound round material i may be placed of any of the arbors 5. This box also has a spacer 29. In Fig. '7 is shown a paper disc 3| which may be used as a protection between the other side of the spiral and the box.

It will be noted that advantages of the invention are that it is compact, rigid and may be cheaply made fromcorrugated or like board, as to any or all parts.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

We claim:
