z Claims. (c1. 22a-z3) This invention relatesto telescopic containers. the containers being relatively tall and being inherently rigid and adapted for ready packing and unpacking of various articles contained therein, and being further characterized in that a minimum number of component elements or parts are utilized, the structural characteristics of which' l'dier from the prior art containers oflthe present type. y

lIn the prior art telescopic type containers at least three main component elements or parts `have been utilized, namely, lsuch a carton wherein the outer walls are in two parts, usually an upper part and a lower part. and` these two parts Vhave free edges that-abut, in most instances approximately midway of the length of the same. The other main component element or part is a liner which in some instances `is substantially coextensive in length with the height of the container and others wherein this liner is also divided intermediate its ends and has abutting free edges. Where an access opening or access door is provided in one wall of the liner, the same is approximately one-half the length of the liner or intermediate the ends thereof and when the free edges of the outer wall sections or parts are in abutting relationship, this abutting relationship occurs closely adjacent the upper edge which defines in part the access opening in one wall of the liner or the point of pivotation or hinging of the door. Thus when the two outer parts have their free edges in abutting relationship with the liner inside thereof, the upper part of the outer casing either extends over the door or the access opening as the case may be.

In the present-invention the overall shape of the container is rectangular and it consists of only two main component elements, namely, an inner one-piece rectangularly shaped section and an outer rectangularly shaped one-piece section. These sections have interconnected walls and right angle corners. Like the prior art containers each section has a ilanged cap thereon and' permanently secured thereto adjacent one end, thus providing a free end for each section. The inner section of the present invention is of greater length'than the outer section. The outer section is adapted to snugly telescopically and slidingly engage the inner section. The flange on the inner section surrounds the same adjacent one end thereof. This inner section isvprovided with a vertically hinged door that comprises substantially one-half of one of the walls thereof and the same is hinged at one right angular corner and thus exposes an opening for packing and unpacking the container when the outer section has been removed from the inner section. j When the inner and outer sections are in their telescoped arrangement the free end edge of the outer section rests on the marginal seat formed by the cap flange adjacent the end of Athe'inner section. This provides for a continuous and uninterrupted length of the walls constituting the outer section from the top to the bottom thereof where the free edge engages the lmarginal seat formed by the upturned flange on the inner section and when the two said sections are thus interengaged the outer section extends over the hinged door and maintains the same in closed position. 'Ivhe aforesaid structure inherently results in an effective reinforced container throughout in that the outer wallsof the outersection are continuous from top to bottom and thereby reinforce the, inner walls which constitute the inner section. The dimension of the height of the walls of the inner section which are of greater length than the walls of the outer section is such that when the-free end edge of the outer section rests on the said seat provided by the ange adjacent the end of the inner section, the free end ofthe inner section will be disposed interiorly of the outer section and engage adjacent opposite portions of the inner side of the cap or any closure member that mayA be positioned thereat. The difference of the greater length of the inner section relative to the outer section is determined by the width of the flange of the cap adjacent the end of the inner section and this d iilerence is usually equal to the width of the flange adjacent the end of the inner section.

In the present container any end thrust from either of the caps that are adjacent the ends of the inner and outer telescoping sections or any weightthat may be applied when the sections are telescoped and with the free end edge of the outer section in engagement with the marginal seat formed by the upturned flange of the cap adjacent the end of the inner section will be imparted directly to this vilarlge and as the flange is securely engaged withthe walls of the inner section there is thus provided a very rigid seat and a means of transmitting the thrust or weight directly to the bottom of the container as distinguished from the prior art containers wherein, as aforesaid, the outer wall 'or section is divided intermediate its ends and any end thrust or weight, therefore, is applied directly to the said outer wall where the edges of the two parts comprising the same abut or contact each other.

In view of the foregoing it is an object of the present invention to provide a telescopic type of container that is relatively tall and subject to tan'gularly shaped gages the same or opposite points. Another object of heavy duty and wherein the same consists of only two main component elements, namely, an

' inner and an outer section, and with each section provided with flanged caps the flanges of which are secured to each section adjacent their A ends and each section having iree end edges and the free end edge of the outer section engaging the edge vofl the flange on the inner section and there being a hinged door in one of the walls of the inner section.

Another object of the invention vis to provide a container comprising iniier and outer snugly 'slidable engageable telescopic sections wherein each section at one end thereof is provided with amused cap, the ilanges'being secured to the 'a telescopic type container-that is relatively tall vand consists of two mainf component elements,

namely, inner and outer similarly formed recsections, the inner-section being', of greater length thanLthe outer section and provided at one end thereof with a flanged cap with the flanges secured tothe side wallscomj prising this section and exteriorly thereof and denning an upwardly facing marginal seat that surrounds lthe saineadjacent` one end thereof and each of the lsections having'free end edges and vwhen the said sections are in telescoped arrangement the `free end edge of the outer section is supported on the said seat Vand the free end edge ofthe inner section is disposed interiorly of the upper capped end of the outer section and enother closure means therein at the invention isto provide a telescopic' container that is relatively tall and comprising substantially similarly shaped inner and outer sections, the outer section being composed of interconnected walls Awith right angularly .bent corners and being continuous or uninterrupted throughout .its length and having a free edgel that is adapted to engage a seat formed by a closure adjacent the end of the inner section.

z Another object ofthe invention is to provide a telescopic type container that is relatively tall "and consists of inner and`outer telescopic sections each' of which has flanged capsecured adjacent one' end thereof andthe free. edges of the flange of the cap on the inner section defining an upwardly facing marginal seat that surrounds the same adjacent one endfthereof and the walls constituting the outer section being continuous and uninterrupted and the o uter section having a free edge that contacts the said marginal seat, and the vinner section being'of .greater length than the outer section so that when the said free end of the outer section is in engagement with the marginal seat the free end of the inner section will be disposed interiorly ofthe cap of the outer section and in engagement therewith and the dieren'ce of the greater length of the inner section relative ,to lthe outer section being determined bythe width of thel flange adjacent the end of the inner section and the width of this With the above and other objects in view. the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the laccompanying drawings and pointed out in the claim hereto appended, it being understood that various changes in the form, proportions, and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, my linvention is shown embodied in a relatively tall, heavy duty shipping container comprising an inner, upwardly opening goods receiving section A 'and an outer, downwardly opening slip 4cover section B adapted to telescope snugly over the open end of said inner section. The two sections are preferably made-entirely of corrugated board,"ilber board or other bendable material.

The goods receiving section comprises a foursided tubular body i made by bending a rectangular blank along three score lines disposed between and parallel with two opposite ends thereof and securing said ends together through the length of the corner formedl thereby preferably by means of lower and upper adhesive strips 2 and 3, respectively. The tubular body i is closed at its bottom or lower end by four closure -iiaps I and a cap 5. One of the closure flaps 4 is formed on the lower end of each of the four side walls of the tubular body i, the closure flaps o! two opposite side walls being bent inwardly into edgewise abutting relation and the closure flaps of the two other opposite side walls being, bent inwardly into edgewise abutting relation over and into contact iiatwise with the two ilrst mentioned inwardly bent closure flaps. The cap i for the bottom of the upright tubular body I of the goods. receiving section A seats against .the two folded over lowermost closure flaps l and has side marginal .flaps or flanges 6 that are bent upwardly against the outer faces of the corresponding side walls of said body and are permanently secured atwise thereto by staples or other suitable fasteners 1. The flanges on two opposite sides of the cap 5 have end tabs l that are bent around the adjacentv corners -of the tubular body and are covered by the depending end flanges on the two other opposite sides of said cap and are secured in place by the fastening staples 1 therefor. The thus securedvilange provides a rigid and upwardly facing marginal seat that surrounds the inner sectionl A adjacent one end thereof.

One of thev two adjacent side walls that are Secured together, at one corner of the tubular body I of the goods receiving section A bjLthe of the carton comprises a four-sided open-ended 1 tubular body II .of a width adapted to snugly telescope over the upper end of the tubular body I of the goods receiving section A. The tubular body of the outer slip cover section is made from a`rectangular blank which is bent along three lines between two opposite ends thereof and said ends connected at one corner of said body by an adhesive strip I2 that extends from top to bottom s thereof. The upper end of the tubular body II of the outer slip cover section B is closed by a cap I3 which seats thereon and has depending side marginal flanges I4 that are permanently secured by staples or other suitable fasteners I5 flatwise to the outside faces of the corresponding side walls of said body. The flanges on two opposite sides of the cap I3 have end tabs I6 that are bent around the adjacent corners of the tubular body and are covered by the depending end flanges on the two other opposite sides of said cap and are secured in place by the fastening staples I5 therefor.

In packing the carton, the tall goods receiving section A is placed in an upright position without the uppermost tape 3 applied thereto, thus permitting the door I to be swung open about the closed corner formed in part thereby to provide a side opening through which easy access may be had to the lower portion of said section for packing. After the section A has been filled through the side opening thereof, the hinged door I0 is then swung back into wall forming'position and may be secured in said position by the uppermost adhesive corner strip 3. The slip cover section B is then telescoped downwardly over the lled goods receiving section A, the height of the tubular body II of said cover section being such that the cap I3 thereof seats on the upper end of the section A and the lower end of said body seats on the upper edges of the upturned side flanges 6 of the bottom cap 5 of the section A. The closed carton may then be bound with crossed metal securing vbands or strips I1 that extend around the top, bottom and sides thereof and are locked in contracted position by means of suitable coupling members I8.

The above carton is of a simple and inexpensive construction; and it permits easy access to be had to the lower portion of the tall goods receiving section for packing. The wide access door I0 vis formed merely by slitting one of the two abutting side wall panels of the goods receivingy section A horizontally from side to side, the adjacent closed corner formed in part by said wall providing a vertical hinge for said door. The door may be secured in closed, wall forming position by the uppermost corner strip 3; and this strip together with the lowermost corner strip 2. secure the two abutting side wall panels of the tubular body I of the section A together in corner forming relation from top to bottom of said tubular body I. The turned under closure flaps l and cap of the goods receiving section A greatly increase the strength, durability and loadsupporting capacity of the lower, wear receiving portion of said section; and the upstanding side flanges 6 of said cap hold the bottom edges of the side walls of the slip cover section off the floor, thereby preventing floor moisture from reaching said bottom "edges of said side walls of said cover section and rising therein by capillary attraction.

In view4 of the foregoing it is clearthat there is provided a container that is relatively tall and which possesses novel structural characteristics comprising the inner and outervtelescoping sections, the novel marginal seat'that is provided adjacent one-'end of the inner section to cooperate with the free end of the outer section and the vertically hinged door provided in one of the panels or walls of the inner section which permits ready access to the lower and upper portions thereof during packing and unpacking of the same.
