a corporation of Indiana Application September 12, 1936, serial No. 100,483 3 Claims. '(01. 206-46 My invention relates to packages or containers and has to do more particularly with a package mation thereof and, after the material has been felted and formed into a bat, the material has been compacted sufiiciently to retain its shape so as to permit its handling by a workman. After cutting such material into bats of a convenient size, it is usually packed into cartons for shipment, with a separator of paper or the like be tween the bats, whereby a workman can withdraw the bats from the package by grasping the edges of the separator sheets.

Such material has certain disadvantages. For example, the use of a binder involves an additional expense and also introduces certain engineering problems into the process of manufacture. Furthermore, the presence of a substantial amount of binder in the finished product reduces the efiiciency of the material as a heat insulator and detracts from its fireproof qualities.

However, in spite of such disadvantages, bats are considered highly desirable because of their convenience of handling.

85 It has long been customary in the rock wool industry to produce a product known as loose woo, which consists of fibers produced without a binder and customarily packed loosely in bags or the like. Such material has been used by withwhere desired, as in a wall or the like. Although such material is superior to the bats so far as thermal efiiciency is concerned and is considerably less expensive to'produce, it obviously is inconvenient to handle since it will not hold its shape and tends to fall in a heap when placed in a vertical wall or the like. It has heretofore been found impractical to pack such unsized mineral wool in packages such as bags, etc. in the form of a "bulk'bat, i. e., a

loose stack of Stratified interlaced fibers, because it is practically impossible to handle such 'material inthis condition. When attempts are made grasping the edges of a plurality of strata, the

drawing handfuls from the bag and applying it to withdraw such material from the package by material breaks in the fingers and cannot be withdrawn in the form of a bat.

, An object of my invention is to provide a bulk bat of mineral wool in combination with'a package which isso designed that the package may be partially removed from the material so as to expose a portion thereof, whereby the hands of a workman may be inserted under a predetermined thickness of material, and such material thus be easily removed as a bat and deposited as such in a wall or other place where desired. I thus make available mineral wool'in its preferred unsized condition and so disposed that a workman may obtain a bat'of the same. of any desired thickness. My invention thus provides all of the advantages of the sized bat along with those of loose wool, with none of the disadvan 'sald material is being used.

invention is to provide In accordance with my invention, I provide a package or carton in which a bulk hat of rock wool may be packed and sealed for shipment, said carton being capable of being partially opened along weakened areas, exposing the contents, so that bats of,any desired thickness may be removed.

My invention will be more fully understood by reference to the drawing forming a part of this specification and illustrating a preferred embodiment of my invention, wherein Fig. 1 is a perspective view of a closed carton embodying my invention; and

Fig. 2 is a perspective view of a package of bats 'from which the carton has been partially stripped to permit unpacking said material.

The numeral it refers to a carton formed of beaver board, chipboard or other suitable inexpensive material, said package being preferj ably in the form of a rectangular parallelepiped and having side walls 822, each of said side walls having a hinged flap it at the top thereof, and a similar flap (not shown) in the bottom thereof. Said flaps fold inwardly as shown in Fig. l to close the package for shipment and storage.

The corners lt which connect the side walls l2 are weakened, so that, after the package has been opened, said side walls may readily be stripped downwardly along said weakened areas it, as in the manner of peeling a banana, rendering the contents 2% readily accessible.

The contents oi'the pmkage comprise a bulk hat 2! of mineral wool or the like. Said material, as described above. consists of mineral wool fibers which have been deposited on a traveling belt or other surface in loosely felted, stratifled condition and then cut to a predetermined size so as to be readily disposable within the package.

It will be apparent that, in accordance with invention, the contents will be readily accessible, after the sides of the package have been partially stripped away, as shown in Fig. 2. The workman may remove a hat of predetermined thickness by merely inserting his hands under the desired thickness of the material and gently wot-mus such material loose from the strata below his hands. He will then hold a bat which may conveniently be disposed in a vertical wall or in any other position and which will retain its shape without collapsingin the manner c a: teristic of loose mineral wool.

It will thus be seen that, in acordance with invention, I have provided, at a lowcost, mineral wool or the like in its preferred condition, without binder, and in such form that it may be quickly and expeditiously handled by a workman.

Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art, and hence I do notwish to be limited to the specific forms shown or uses mentioned,

ammo-1a except to the extent indicated in the appended claims, which are to .be interpreted as broadly as the state of the art will permit.

I claim:.

1. In combination, a bulk bat of mineral wool having parallel planes of cleavage, and a container therefor comprising side walls secured together along weakened corners, whereby said walls may be stripped from the contents along said corners, and closure flaps at the top and bottom of said side walls, said cleavage planes being perpendicular to said corners.

2. In combination, a bulk bat of unsized mineral wool having parallel planes of cleavage, and

a container therefor comprising side walls secured together alon g weakened corners, whereby said walls may be stripped from the contents along said corners, and closure flaps at the top and bottom of said side walls, said cleavage planes being perpendicular to said corners.

3. In combination, a bullehat of fibrous maand bottom of said side walls, said cleavage planes being perpendicular to said corners.

MICHAEL LUERY.
