c 2 for other purposes. For instance, the invention 8 Claims.

This invention relates to containers for conjoint packaging and dispensing purposes, especially as constructed from foldable sheet material such as paperboard, commonly used in the folding paper box industry.

The use of incendiary bombs in modern warfare has rendered advisable the keeping on hand by householders, shopkeepers, air-raid wardens, and others, quantities of sand or similar extinguishing material ready for instant application to any incendiary bombs which may fall nearby. Because of the intense heat generated by incendiary bombs and the spitting of burning magnesium metal from certain types thereof, it is most expedient that they be handled at arms length, so to speak, which ordinarily requires long-handled implements, such as shovels, for proper and careful application of the extinguishing material at comparatively long range.' Again,

the very nature of the extinguishing materialgranules or powderrenders its storage in bulk,,

as in buckets or heaps on the floor, together with shovels, untidy and generally undesirable.

Accordingly, it is an object of this invention to provide a container in which sand, or certain pre-:

pared fire-extinguishing materials, may be packaged for direct sale to the user in a form convenient for storage and ready for instant application without the use of long-handled implements, which may not be immediately available;

It is an object to provide a container for the above purpose which shall be closed tight-up to the time of use, and which shall be very simple to open and to make ready for use.

above objects is the provision of anelongated box made up of telescopic sections and having a dispensing end and a closure therefor, which closure serves to positively lock the individual telescopic box sections in retracted, telescoped position, andv yet may be readily torn open to free the teleextended box during the application of its contents to a burning incendiary bomb or other con- 'flagration.

' While the invention was developed primarily vfor the above specified purpose, its structural and functional features render .it very advantageous Outstanding in the accomplishment of the 35 may be employed insuitable forms for the packaging of fertilizers, rodent-exterminating- -powders, cleansing powders, and other substances the dispensing of which may-be disagreeable or dangeroustothe person; or again, theinvention may be employed for packaging substances in general,

which are to be-deposited in a remote or inaccessible place.

Both the inner box section I0, see Fig. 11, and

the outer box section I I, see Fig. 10, are of elongated formation, so that, together, when extended relative to each other, they provide a length be---' tween dispensing opening and handle portion of several feet, see Fig. 5. This length is, of course, predetermined as desired by the structural. di-

' mansions of the component-box sections, and may be greater or less as required in any given instance. The usual length for the indicated purpose, is approximately four (4) feet, which, when added to the length of the user's arm, gives an adequate long-range reach" during use.

The sealed end I2 of-the container becomes the dispensing or discharge end thereof when the same is extended for use, as shown in Fig. 5, while the protruding opposite end portion -I3 of the inner box section III becomes the handle of the container.

It is preferred tl'i'atthe individual telescopic box sections be of folding-box formation, that is, formed from suitably cut and scored blanks of foldablesheet material, customarily paperboard.

In the illustrated embodiment, the inner box section I is formed by folding and gluing the blank of Fig. 11, while the outer box section II Is formed by folding and gluing the blank. of 1'18. 10.

The blank of Fig. 11 comprises the two mutually corresponding wall panels I5, the two mutually corresponding wall panels IS, the lateral glue lap I1, the pairs of conventional end glue flaps I8 and I9 for providing the conventional glued end 20, Fig. 8, the pair of limit-stop tabs 2|. forcontributlng to the limiting of the extent of tele-' scopic extension of the two box sections relative to each other, and the pair of dispcnsingwpening closure flaps 22. 1 J

The inner box section II) is formed from the blank of Fig. 11 by folding the blank on its indi* cated score lines, and by gluing the glue lap I! to the inner face of the outlying wall panel l5, at the free-edge margin thereof. The box section is then in collapsed tubular condition, and may be set-up by interfolding and sealing the pairs of closure glue flaps I 8 and l9v in the usual overlapping. relationship. The limit-stop tabs 2| are folded outwardly and downwardly against the outer faces of the respective wall panels I from which they extend.

The blank of Fig. 10 comprises the two mutually corresponding wall panels 25, which correspond to the wall panels I5 of. the blank of Fig. 11, the two mutually corresponding wall panels 26, which correspond to the wall panels I6 of the blank of Fig. 11, the lateral glue lap 21, the pair of limitstop tabs 28, which correspond in configuration to the limit-stop ta'bs 2I of the blank of Fig. 11, the closure-supporting flap 28, and the closure tongue panel 30 with its seizure-tab member 31, for

grasping in order to tear or rip off the closure thereby opening the sealed discharge or dispensing end I2 of the container and releasing the box sections for telescopic extension.

The outer box section II is formed from the blank of Fig. 10 by folding the blank on its indicated score lines and by gluing the glue lap 21 to the inner face of the outlying wall panel 26 at the free-edge margin thereof. When this box section is set-up into tubular formation from its collapsed condition, the lirnitstop tabs 28 are folded inwardly against the inner faces of the respective wall panels 25 from which they extend, and are thus directed upwardly within the box section.

The wall panels I6 are preferably wider than the wall panels I5, whereby the resulting box section III has an oblon formation, imparting enhanced resistance to bending, and providing increased positive action of the limit-stops; the end closure flaps 22 are preferably divided from the respective wall panels I6, from which they extend, by means of respective lines of perforations 23. so they can be easily torn free during the unsealing and opening of the container for telescopic extension and dispensing of contents.

' The container is assembled from the two individualbox sections III and I I, preferably by gently .and passing such inner section upwardly within such outer section until the closure flaps 22 thereof protrude from the open upper end of the outer section and assume the positions, relativ to the closure elements of the outer section, clearly shown in Fig. '7. The carton is then ready to be filled with suitable contents and sealed.

The closing and sealing operation is accomplished by swinging closure-supporting flap 29 of the outer box section inwardly, by swinging the closure tongue panel 30 down thereover to cover the dispensing opening 32 of the carton, and by applying glue to the closure flaps 22 of the inner section and swinging them down so that one lies over and adheres tothe other and both lie over the closure tongue panel 30, as illustrated in Figs. 1, 6 and 8. The seizure tab 3| may hang free, as illustrated, so it may be readily grasped for opening the carton, or, as illustrated in Fig.-12, may be tucked into a slit 33, suitably provided through the adjacent wall panel 25 of the outer box sectionv I I. As thus closed and sealed, the inner box section III is securely locked within the outer box section I I.

In unsealing and opening the dispensing end I2 of the carton when it is desired to apply the contents to a flaming incendiary bomb or other convflagration, or to dispense the contents for other purposes, the seizure-tab 3| is grasped and pulled upwardly and backwardly, as illustrated by Fig.2. Because of the placement of closure tongue panel 30 underneath the sealed closure flaps22, the

result of so pulling the tab 3i is to .rip off the the handle-portion I3 thereofis firmly grasped in one hand, while the other hand is used to extend the outer'box section II relative to thein'ner section is dimensioned to fit and slide snugly within the outer box section, the pair of outfolded limit-stop tabs 2| thereof will contact the pair of infolded limit-stop tabs 28 of the outer box section in substantially edge to-edge abutment beforethe two sections are pulled completely apart, thus providing a positive maximum limit to the extent of elongation of the carton.

It should be noted that the fire-extinguishing material 35, which ordinarily has considerable Weight, is all initially packed into the inner'box section In. After the carton has been extended,

or even during the extension thereof, such matethe user can keep the greater part of the total weight of the material contents of .the carton at or adjacent the handle portion l3, which, of course, is the part of the box directly supported by the user. Consequently, no serious force couple is established between the held end of the carton and the opposite and remote discharge or dispensing end thereof. Sheet paperboard material is, thus, adequately strong for use as the structural material of the carton, and no undue strain is placed on the hand or arm of the user.

As before stated, the invention is not restricted in its use to the packaging and dispensing of fireextinguishing materials, but may be employed wherever its peculiar structural and functional characteristics render its use advantageous.

Whereas the invention is here illustrated and described with respect to a certain preferred specific form thereof, it should be understood that various changes may be made in such specific form and various other specific forms may be constructed from time to time by those skilled in the art without departing from the spirit and generic purview of the invention as set forth herein and in the claims which here follow.
