3 Claims.

This invention relates to afolding container which is more particularly intended for packaging choice merchandise such asfiowers, elegant articles of dress, jewelry and fancy goods, while the. same are on display or for sale and also for presentation on special occasions when an artistic enclosure for the gift or the like is desirable.

Heretofore. such articles, have usually been wrapped in paper or enclosed in boxes of ornamental paper which concealed the articles from view and protected them against possible soiling by handling, and the same were also displayed in transparent show cases to protect them from dust.

These means of displaying and packing goods of this character are unsatisfactory in that the goods usually cannot be displayed to the best advantage and they are also liable to suffer when rehandled while packaging the same ready for presentation or delivery.

'It is the object of this invention to provide a foldable container which can be compactly stored and shipped in a knock-downcondition and readily erected into the form of an enclosure in which the respective merchandise may be displayed without liability of becoming soiled or injured by handling and in which the same can be delivered to the recipient without further wrapping, and to provide such containers at comparatively low cost.

. In the accompanying drawings:

Fig. l is a perspective view "Of a "folding box or container embodying a satisfactory form of my invention.

i Fig. 2 is a vertical longitudinal section of the same in its erected for-m.

Fig. 3 is a vertical transverse section of the same.

. Fig. 4 is a perspective view of body and associated parts of the container-made in accordance with this invention 'showing'the-same spread out in flattened condition suitable for compact storage :or transportation.

Fig. 5' is a similar view of the cover forming part of the container.

Fig. 6 is a similar view, on a reduced scale, of the cover showing the same bent into UTshape or how form, preparatory to-being assembled withthe body of the container.

Figs; '7,- 8 and 9 are fragmentary sectional views on an enlarged scale of the joints, respectively, between the-transverse edges of the bottom and the end walls, thelongitudinal edges of the bot-Y 2 tom and the cover and the ends, of the cover with the end walls.

In the following description like reference characters indicate corresponding parts in the several figures of the drawings:

Inits general construction this ioldable container or foldingbox comprises a body, a cover, and tying means for holding the body and cover in an assembled .position relative to each other.

Although the bodymay be constructed of any suitable material it is preferable to use for this purpose cardboard. or like sheet material which is vout so as to form a rectangularbottom "I which is arranged horizontally when in use and two vertical walls III which are arranged transversely at opposite transverse end edges of the bottom. These end walls are preferably made integrally with (the bottom from a singleblank of sheet material and'the same are bent .orturned upwardly from a position in which they are c'oplanar withthe bottom into a position in which they project upwardly from the bottom and at right. angles thereto. To facilitate such bending or turning of theend walls relative to the bottom the, blanknoi sheet material of which the same are constructed is provided on its outer side with transverse scores, partial or cuts 12, as shown in Figs. 2 and 4.

Each of the end walls has a horizontal lower edge 13, two vertical side edges l4 extending-upwardly from the opposite ends of the lower edge, and an upwardlycurved or rounded upper edge I 5 which connectsthe-upper ends of'said vertical edges, as shown inFigs. 1, 3 and 4.

At its opposite "longitudinal edges the bottom is provided with .two inwardly opening longitudinal grooves 9 which form .part of the fastening meansfor detachably connecting the cover to the body. ,Each of these grooves includes an pper retainingstripl 6 arranged lengthwise over one of the longitudinal side edge portions ofthe bottom and is preferably formed integrally with the bottom andfbent or turned upwardly from the bottom andinwardly over the upper side of the l'atter,'th'is bending. being facilitated by ,providing the blank sheet material from which the bottom andgroove strips are formed with longitudinal scoring on the outer side of the corner between the bottom and these strips, as shown at 17in Fi s. 1, 3 and 4.

,Eachofthe retaining strips is held in its folded position relative to the body by fastening means consisting preferably .of wire staples l8 or stitching connecting the outec-part of the respective retaining strip with the corresponding outer part of the longitudinal edge portion of the body. The inner part of each retaining strip is not connected with the body and is spaced therefrom so as to form an inwardly opening groove between the underside of the inner part of the retaining strip and the upper side of the adjacent or corresponding opposing part of the bottom, as shown in Figs. 1, 3, 4 and 8.

The cover of the container is preferably constructed from a single sheet of flexible transparent material, such as cellulose acetate or other plastic, which is bent into bow form to provide two upright longitudinal side walls l9 and a transversely curved or rounded top 20 which connects the upper edges of said side walls, as shown in Figs. 1, 3 and 6.

Each of the side walls is provided at its lower edge with a horizontal longitudinal coupling flange 22 which in the erected position of the parts of the container, projects outwardly into engagement with one of the longitudinal grooves 9 at the corresponding longitudinal edge of the bottom and forms a detachable connection therewith.

In its bent form the transverse shape or form of the cover corresponds at its opposite ends to the shapes of the top and side edges of the end walls of the body and in the erected position of these members these end walls fit into the opposite ends of the bow shaped cover and form the respective closure parts of the container.

Means are provided whereby the end walls of the body are retained in an upright position within the cover after these parts have been erected which means preferably consist of locking beads or rims 2! which are arranged on the inner side of the cover along the vertical side and curved top parts thereof at opposite ends of the cover. These ribs are of such thickness and arrangement that when the end walls of the body are pressed into the opposite end parts of the cover, the side and top edge parts of the body end walls will be sprung past these ribs from the outer to the inner sides of the same so that when these end walls reach their upright position the resilience of these end walls and that of the cover will retain the vertical and top edges of these end walls in engagement with the inner side of these ribs and thus maintain this part in an erected position.

In addition to the locking ribs the end walls of the body are further retained in their closed position by tying means which also serve as an ornament of the container, which tying means preferably consist of two ribbons 23 normally arranged lengthwise over the top of the cover and having their outer ends connected by stitches 24 or otherwise to the outer side of the upper parts of the body end walls while the opposing inner ends of these ribbons are tied together in the form of a knot or bow 25, as best shown in Figs. 1 and 2.

While the bodies and covers of the containers or boxes are in a spread out or flattened condition, as shown in Figs. 4 and 5, they may be stacked compactly in piles and thus there is a considerable economy in storing and shipping the same.

In the operation of erecting the container the cover is first bent from the flat form shown in Fig. 5 into the inverted U-form, indicated in Fig. 6. The cover is placed over the bottom of the body section and the retaining flanges 22 are engaged with the grooves 9 between the retaining strips and the longitudinal edge portions of the body, in which position the parts are maintained by the resilience of the cover. Thereafter the articles to be packaged are introduced into the space between the bottom and the cover through the opening at either end of the latter and then the end walls are turned upwardly into a position in which the same close the opposite ends of the openings between the bottom and the cover. The packaging operation is completed by tying together the ribbons above the cover.

The procedure of enclosing an article within this container may be effected expeditiously and economically and. without involving undue cost.

Moreover the article when thus enclosed may be freely inspected when on display without liability of the article being soiled or disarranged.

In addition to protecting the article which has been packaged by means of this container, the assemblage as a whole presents a very neat and attractive appearance and tends to promote sales of goods.

I claim as my invention:
