SPECIFICATION forming part of Letters Patent No. 601,568, dated March 29, 1898.
Application filed August 2 3 l 8 9 7.
To all whom, it 771/601/ concern,.-
Be it known that I, PHILLIP I. JAcoBY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Packing-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artv to which it appertains to make and use the same.
My invention relates to improvements in boxes, and more especially to that class of boxes designed for use in preserving and packing crackers, biscuits, candies, dried fruits, cigars, dac. y The object of the said invention is to provide a packing-box whereby the better preservation of its contents is obtained by the total exclusion of airtherefrom.
To accomplish this object, my said invention consists of the novel construction and' combination of parts hereinafter more fully described.
Referring to the accompanying drawings, in which similar parts are represented by similar letters throughout both views, Figure 1 is a perspective view of my box, showing the hinged cover open and the sliding cover partly withdrawn; and Fig. 2 represents a central transverse section of the saine.
A represents the body of a box, preferably of tin, though any suitable material for the purposes above stated may be used. The sides a and end d of this box are crimped, as at CL2, around their upper edges and bent inwardly above this crimped portion to form the iange a3. This leaves between the crimped portion a2 and the ilange d3 a recess, groove, or sliding way a0, into which is adapted to pass the sliding cover B, which, as shown in the drawings, is partly withdrawn. This sliding cover may be of a single thickness of tin, pasteboard, or any suitable material of any desired thickness, and is provided at one end with the downwardly-extending iiange b, which is adapted to engage the end a4 of the box when the cover B is closed. In order to cause the sliding cover B to more tightly close the box, a strip of rubber, felt, or other suitable material C is secured to the upper inside edges of the sides of the box and ex- Serial No. 649,228. (No model.)
tends sufficiently close to the flange a3 to cause the cover B, when inserted in the sliding ways a0, to tightly engage the said strip and thereby as totally exclude the air from the interior of the box as could be done by a simple and practical means. The flange a3, extending well over the edge of the sliding cover and the latter being engaged below by the strip C, affords a means of closing the box which is not injuriously affected by frequent withdrawals of the cover.
In addition to the sliding cover B the box is provided with the hinged cover A', which is provided with the anges a5 and hinged to the flange a3 of the box, as at 0,6. When the sliding cover is closed, this hinged cover A may be closed also, and by its iianges a5 not only prevents the sliding cover from being withdrawn, but affords a more perfect exclusion of the air from the interior of the box.
The simplicity, novelty, and extreme usefulness of such a box for preserving articles will immediately suggest themselves to any one.
The ordinary hinged tops of cracker, cake, cigar, and other boxes having once been opened become sprung and seldom ever fit tightly again. To keep an article fresh in such boxes, oilpaper, tin-foil, and other means are resorted to, but this is not only troublesome and sometimes impossible, owing to the absence of the wrapping substance, but is, as compared with my device, not efficient. An article placed in my improved box with the covers closed is entirely excluded from the external air, and'when desired to remove the article is easy of access. As my invention obviates vthe use of sealing, such as paper pasted around the edges of the box to exclude the air, the contents will not be affected should the box for any reason become wet.
There are many other advantages possessed by my said invention which will readily suggest themselves to those familiar with the art to which it rela'tes; and while I have shown a box in the drawings of a-particular shape it is obvious that I do not confine myself to any shape or size of the box, and it is furthermore obvious that my said invention is capable of many modifications which may be made without departing from the spirit of the invention; but r IOO What I do claim, and desire to secure by Letters Patent of Jthe United States, is-
1. A packing-box having the upper edge of its sides and end crimped to form a groove and an inwardly-extending flange, a strip of packing secured to the inside of the sides and end of said box by said groove, a cover adapted to slide in said groove and contact with said packing, substantially as described.
' 2. A packing-box having the upper edge of its sides and end crimped to form a groove and an inwardly-extending flange, a strip of packing secured to the inside of the sides and end of said box by said groove, a cover having a downwardly-extending ange at one end and adapted to slide in vsaid groove and contact with said packing, substantially as described.
3. A packing-box having the upper edge of its sides and end crimped to form a groove and an inwardly-extending flange, a strip of packing secured to the inside of the sides and end of said box by said groove, a cover adapted to slide in said groove and contact with said packing, and a second cover hinged to the side of said box and adapted to inclose the top of the same and the said sliding cover, substantially as described.
4. A packing-box having the upper edge of its sides and end crimped to form a groove and an inwardly-extending flange,`a strip of rubber secured to the inside of the sides and end of said box by said groove, a cover having a downwardly-extending liange at one ,end and adapted to slide in said groove and contact with said rubber strip, a second cover hinged to the side of said box and adapted to inclose the top of the same and the said slid- PHILLIP I.
