To all 'whom t may Concern.'
Be it known that l, EUGENE F. NIssnN, a citizen of the United States, residing at .Alameda, in the county of Alameda and State of California, have invented new and useful Improvements in Safety-Containers, of which-the following is a specification.
This invention relates to a safety container.
-It is lthe principal object of this invention to provide a fabric or paper container within which articles may be placed and held in a manner to prevent them from being removed without mutilating some portion of the container and thus insuring detection, the present structure being designed to form a neat package when a few articles or documents are placed therein and to be expanded when desired to readily accommodate a large number of documents, at all times being fastened by a seal of one size, thus ynot only conserving the material used to seal the :envelop but also insuring that the documents within the envelop will be held in a manner to prevent unauthorized access thereto and 4accidental bursting of the container in transit. r
The present invention contemplates the use of a blank forming a body panel, a back panel integral therewith, aps at the opposite sides of the body panel and a closure flap for the end` said panels and flaps being adapted to be folded to form a smooth .front and 'back panel and collapsible edges or gussets, the panels and flaps overlapping and unitingwith eachother in a manner to precludethe possibility of access to the container.
The invention is illustrated by way of eX- ample in the accompanying drawings, in which Figure 1 is a view in plan illustrating thc blankof the. container and further indicating indotted .lines the scoring marks for the various folds.
Fig. 2 is a small perspective view illustrating the completely formed container in its open position.

Fig. 14 isa view in section illustrating' a fragmentary portion of the top of the container when filled and nthe gussets completely distended.
In the drawings, 10 indicates a blank from which a container 11 is formed. This blank may be made of fabric or paper and cut as indicated in Fig. 1 of the drawings. When formed a rectangular body panel 12 will be produced bound by the dotted lines A, B,V C and D. Formed as a continuation of one end of this panel is a closure flap 13 which is of a width equal to the distance'between the lines B and D and extends from the line A t0 its outer marginal edge. EX- tending from the opposite end of the body panel is a back panel 14, This panel is of a width equal to the width of the body panel and ofy a length equal to that of the body panel plus the distance between the scoring lineI C and a scoring line E, which distance represents the thickness of the con tainer when its edge gussets aie completely distended.
Formed at opposite sides of the body panel are outer and inner side flaps 15 and 16. These flaps are rectangular in shape and are of a length equaling that of the body panel plus the thickness of the container when filled. The edges of these flaps at one end terminate on a line representing a continuation of the scoring mark E upon the back panel, and at the opposite end B and D, respectively, a distance equal to the thickness of the container when filled, this distance corresponding` to the distance between the end scoring marks A and F and the marksC and E. Intermediate fold marks I are made midway between the body panel and the scoring marks G and H and thereby form gussets along the opposite sides of the container. Similar marks J are made between the ends of the body panel and the scoring marks E and F to form gussets at the opposite ends of the container. Prior to folding the blank theflap 15 is gumined along its edge portion, while the back panel 14 is likewise guinined along its opposite side edges, as indicated at 1S and 19. The initial step in forming the container is to bring the side flap 15 over the flap 16 and cause the contiguous faces of these two aps to be glued together by the gummed surface 17, thus forming a. rectangular compartment 20, as indicated in Fig. 4f. After the flaps have been thus glued their lower ends are folded along the oblique scoring lines K which terminate atv the gusset fold lines I and there intersect short fold lines L. `Referring to Fig. `5, it will be seen that this operation will cause the Haps to be folded down upon themselves and thereafter produce a fold in a single plane across the bottom of the container, this last-named'. fold being represented by the portion of the flaps subtended by the scoring lines L and the portion of the scoring line K extending from the lines C to their point of intersection with the lines L. The body panel 12 is then folded on the line C and creasedl on the line J, this creased portion being folded into the gusset previously formed bythe side flaps. The gummed surfaces 18'y and'.
19 of this body panel will adhere to the gusset fold of the side flaps and act to p roduce a completely sealed gusset extending entirely across the end of the container, as shown in Fig. 6.
The folded and glued lower ends of the side flaps are then folded upwardly and outwardly along their ,scoring marks C, as shown in Fig. 7, and thereafter completely concealed beneath the back panel 14 as it is brought up over the flaps 15 and 16 and fastened thereto by the adhesive material at 18 and 19. The compartment 2O will still. be rectangular in shape, as shown in F 10, at which time the upper ends of the iaps 15 and 16 are folded along their inclined scoring marks K to bring the portion of each flap adjacent the body panel inwardly and in a single plane extending across the open mouth of the compartment. The naps are both folded along the scoring marks I to form an upper gusset, after which the central portion formed by the two flaps is' folded inwardly on theline A and outwardly along the line J, thus completing a gusset at the top of the container. The closure flap 13 is then creased inwardly along the line A and outwardly along the line J, thereafter be'ing folded over the back panel along the scoring line F.
It will be observed that a straight gusset will thus be formed entirely across the op'- posite ends of the container and that similar gussets will be formed along the opposite sides of the container, as the portion of each of the flaps 15y and 16 is creased in wardly along the scoring marks I and folded down so that on one side the scoring marks B and G will coincide and on the other side the scoring marks D and H will register. The edges formed along the marks B and D will define the sides of the body panel 12, while the edges formed along the marks G and H will represent a width equal to the width of the body panel and corresponding to the width of Athe back panel 14. After the formingA operation a metallic fastener 21 may be applied to the back of the container and may be fastened through the back panel and the flaps 15 and 16. A plurality of eyelets 22 are placed near the end of the flap 1? and are designed to separately yregister with the fastener 21 when in its folded and closed position, thus making it possible to compactly seal the closure flap in place, regardless of the number of yarticles or quantity within the container. In commercial use, ther fastening members may be covered by a wax seal 23, after which the imprint rof a mercantile association may be affixed thereupon.
It will therefore be noted that the variflap 13 at the one point by the seal 23. When documents or other valuables khave been placed within the container thus formed and thereafter sealed, as indicated, it will be practically impossible to remove these articles without materially multilating the walls of the container. In the event that the walls are steamed, it might be possible to separate a back panel 14: from the folded sides of the flaps 15 and 16. However, after this had been accomplished it wouldstill benecessary to loosen the side flaps as held by the gummed surface 17. As these flaps are completely covered by the panel 14, this steaming operation would be di'llicult. Assuming, however, that the attempt was successful, it would then be quite a problem to reach beneath the back panel 14: and between the separated side flaps 15 and 16 to remove the articles from within the compartment and around the edge of the flap 16.
T he container here disclosed will therefore be decidedly simple in its construction and will practically preclude the possibility of access to the contents thereof without breaking the seal, at the same timedoeing easily made from a simple blank and easily sealed without the use of a large quantity of sealing wax.
Having thus described my invention,
what I claim and desire to secure by Letters Patent is:
A safety envelop formed of a single blank of material including a central rectangular body panel, a rectangular back panel emanating from one end of the body panel, a iap panel emanating from the other end of the body panel, rectangular shaped side panels emanating from the sides of the body panel, portions of equal width on said emanating panels contiguous the four sides of the body panel being scored each in three parallel lines to form sides of the envelop with gussets, the eXtreme outer upper and lower corner portions of the side panels' being scored so that they are adapted to be folded and lie, the upper beneath the top gusset to reinforce the same, and the lower between the back panel and the adjacent folded portions of the side panels when the envelop is formed, the outer edge portion of one side panel being gummed, and the opposite side edges of the emanating back panel being likewise treated.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
