TOBACCO HUMIDI'FYING DEVICE Filed Dec. 5, 1942 IINVENTOR. Zo/ef/Vc fir/EX Patented Dec. 19, 1944 y n UNITED STATES PATENT OFFICE TOBACCO HUMIDIFYING DEVICEy Florence L. Gailey, Los Angeles, Calif. Application December 3,1942, Serial No. 467,820
` 1 Claim.
My invention relates generally to the containers of pipe tobacco, cigars, cigarettes and the like and more particularly to a mcistening device which is positioned Within the box or container, for the purpose of converting the same into a humidor, in order to maintain the contained tobacco, or tobacco products, in the desired humid condition.
A further object of my invention is, to provide a humidifying device of the character referred to, having vacuum suction means for detachably mounting said device on the smooth inner surface of the box or container.
With the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangement of parts, which will .be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which: y
Fig. 1 is a vertical section taken through the upper portion of a tobacco box and showing the humidifying device applied to the underface of the cover. v
Fig. 2 is a horizontal 2--2 of Fig. 1.
Referring by numerals to the accompanying drawing, I designates a smoking tobacco box or container, and Il, the cover therefor, which box and cover are generally formed of sheet metal.
This humidifying device, in accordance with my invention, comprises a pad o'r body I2. of fine textured sponge rubber, either natural or synthetic. One very satisfactory porous material that may be used in producing the pads, is known to the trade as Airblown Latex.
The upper surface of this porous body is provided with an extremely thinvskin,` in the upper face of which is formed a number of minute voids or pockets, so that when said upper face is pressed against the smooth underface of the box cover, it Will adhere thereto 1 as a result of the suction developed by the partial vacuum section taken on the line produced in said voids or pockets.
.Prior to being applied to the box cover, as
just described, the pad is squeezed or compressed 'and then permitted to resume its normal shape under Water and as it is porous, said pad will absorb and become loaded '.vith Water.
.After'being applied to the box cover, a thin sheet I2a of vmoistureprooi material such as metal or Wax paper is applied to the underface of the pad, thus preventing the tobacco Within the box from making direct contact With the moist pad.
Thus, While the cover is on the box or containy proved humidifying device applied to the covers simple structure, inexpensive of manufacture,
of conventional tobacco boxes, it will be understood that the devices may be successfully used in containers for cigars, cigarettes and the like providing said containers have smooth inner surfaces for cooperation with the vacuum recesses.
When vthe pads are applied tok boxes of papers, card board or the like they arey secured thereto by the use of waterproof cement.
Thus it will be seen that I have provided a f tobacco container humidifying device that is of and very effective in performing the functions for which it is intende' i It will be understood that minor changes in the size, form and construction of the'various parts of my improved lhumidifying device may ibe made and substituted for those herein shown and described Without departing from the spirit of the invention, the scope of vwhich is set forth in the .appended claim.
I claim as my invention:
A tobacco container humidifying device comprising a bodyof sponge rubber provided on its upper surface with a thin skin in which is formed a plurality of small vacuum suction recesses and a thin sheet of flexible moistureproof material applied to the underface of said body.
