FIBROID CASE Filed Dec. 1. 1957 -2-Sheats-heet 2 will/11111111111111 INVENTOR Herman I Grave Patented Nov. 28 1939 n FIBROD' GASE l Herman L. Grove.

My invention relates to fibroid cases. The object of myin'vention is to provide-a cheap eflici'ent fibroidicase that can be shipped in a fiat condition and folded into form by the user, and that can be closed by a flap portion which is flexible, and held in closed position thereby...

Further objects of my invention will be set forth in the specification hereinafter."

Referring to the drawings which form .a part of the specification, a

Fig. 1 is a view of a blank as it is formed prior 1 to folding. v I t Fig. 2 is a perspective view of the case in its folded condition.

Fig. 3 is a perspective View of the carton or casing as it appears when ready to be used as a wall-case.

Fig. 4 is a plan sectional view of a corner of a casing, taken on line 4-4 of Fig. 3.

Fig. 5 is a view of a corner portion of a casing showing another construction ofmeans for locking the flap portions of the case together.

Fig. 6 is a sectional View taken on line 6--6 of Fig. 5.

Fig. '7 is a view illustrating the use of both a clip and cement for holding the band forming the front upper side of the case together.

Fig. 8 is a sectional view taken on line 8-8 of Fig. '7 and showing the outer front band held by cement at the outer end of the band, the same construction being used at each end thereof to more firmly hold the corner portions together when the cover flap is forced under the band in interlocking the parts.

[0 indicates the blank made of thin flexible material such as fiber-board which for most purposes is between one-sixteenth and one-eighth of an inch in thickness.

The blank is scored on the dotted lines to permit it to be easily folded.

Slots II and I2 are formed adjacent to each other and register when the flap i4 is folded over on the front side portion l3 as illustrated in Fig. 3.

The metal clip construction shown in Figures 3 and 4, is made of stiff soft metal that can be bent after its free end is passed thru the slots II and I2, to the position shown in Figures 3 and 7, the clip being secured in fixed relation to the inner side flap in the usual manner as illustrated at IS in Figure 4.

Each of the front side flaps is cut on the bias as illustrated at H, starting at a short distance from the corner of the case as illustrated at l8 5 Claims. (01.;

g the case.

to formrigi'd corner portions while permitting the front of the casing'to'be open down to the top of the banded lp'or'tion M to permit easy removal. of paper sheets deposited in'the casing.

The ba'ndld presents a smooth upper "edge Ill -5 and serves tostiffen the entire front portion of .Wh'en the cover lporti'on of the casing is'folded in the act of closing, the portion 20 overlies the band l4 and the end 2! is folded on line 22 and 10 I the end 2i is flexed to permit it to be inserted under the band, thus holding the casing closed and held in fastened relation with the cover.

An aperture 23 is made in the end portion '2! to permit the case to be suspended from a nail or hook fixedon a wall.

' Referring now to Figures 5, 6, and 8, the means used to hold the band portion to the flaps I5 consists in forming a tab 24 integral with the band 14 and inserting it thru slots 26 formed in 20 the flaps l5 and 13 so that the free end of the tabs rest on the inner sides of the flaps l5, and by thisconstruction I am, able to construct a case without any further elements and thereby reduce the cost of manufacture materially.

1 In order to strengthen the construction ofthe band I4 I prefer to use cement 28 when using the integral tab construction, thus removing any strain from the tab in the act of bending the end portion 2| when inserting it under the band, 30 and the cement assists in making a more rigid lower edge 29 and so holds the end 2| in closer engagement with the portion I3. I

Where the cement is used it may be applied and the parts joined thereby before shipment while in its flatv condition, or the cement commonly used may be moistened after shipment by the user at the time it is folded into a casing.

Where a large number of the blanks are to be shipped in a bundle, the elimination of the metal clips and the cement surfaces not joined, the blanks rest in flat superimposed relation and require less room fora given number and also are of less weight than when metal clips are attached to the cases.

Having thus described my invention as new:

1. A casing of the character described made of fibroid material formed from a single sheet folded to provide a pocket extending from the top to the bottom of the casing on rear side and open on its front side for a predetermined distance to permit easy access to the pocket, said casing formed with a band at its upper front edge comprising a folded portion which extends g 45 I claim across the casing to reinforce it and to provide a pocket on its inner side, means for securing the ends of said band together and to the front wall of the casing, and a cover portion having a tab end which is scored and may be folded to extend upwardly under said band and rest in said pocket to hold the cover in its closed position.

2. The case construction defined in claim 1, together with; the construction being such that band together. I

3. A casing of the character described made of fibroid material formed from a single sheet folded to provide a pocket extending from the top to the bottom of the case on the rear side and is open on its front side from the top down. ward a predetermined distance, said casing the front thereof and is provided with a laterally extending tab formed integral adjacent to its ends; said case having inner front flap portions provided with slots thru which the adJacent tabs may be passed and rest on the inner sides of said flap portions.

4. The construction defined in claim 3, together with; the cover portion having an end portion adapted to fold and extend upwardly under said band to hold said cover in closed position, and a portion extending over said tab portions of the band.

5. A casing of the character described made from a single piece of fibroid sheet material adapted for shipment in a fiat blank condition and thereafter folded to provide a bottom por= V I tion and a back portion extending upwardly the folding cover portion of the case overlies andconceals the means which hold the ends of the therefrom to the top, a top portion hinged thereto and a front side flap portion extending downwardly therefrom and having its lower end folded to extend upwardly; end portions each of which carries a short flap which extends under the front side of the casing; a front side portion extending from the bottom of the casing the upper end of which is folded back upon itself to form n a band which extends across the casing at a disformed with a band at its upper front edge comprising a folded portion which extends across ta'nce from the top thereof and presents a smooth top edge; and. means carried by said short flaps and engaging said band to hold it to said flaps and to provide a pocket under said band to receive said upwardly extending end portion of the outer front flap and serves as a lock for the easmg.
