This invention relates to a disinfecting and deodorizing device.

It is an object of this invention to provlde a device that will absorb relatively large vol umes of volatile substances, such as disinfectants, deodorizers, perfumes and the like and which will later permit vapors of these liquids to be slowly given off.

It is a further object of this invention to 0 provide a disinfecting and deodorizing device in the form of a wooden block or the like.

Other and further important objects of this invention will become apparent from the following description and appended claims.

I have found that certain light woods, as for example balsa, may be compressed to form a ielding porous substance admirably ada te to absorb liquids, such as perfume oils, is-

In its preferred form, my invention com prises soaking a block of balsa, or other light wood in the desired disinfecting or deodorizing liquid and then compressing the block in a direction at right angles to the grain to produce a block of approximately one-half the original thickness. breaks down the fibre binding material of the wood sufiiciently to produce a springy, porous block.

0 The liquid-in which the blockof wood is soaked may be a mixture of gums, resins, essential oils and essential oil compounds or any desired perfuming or disinfecting liquid.

Preferably, however-,a gum or resin is mixed with the volatile perfuming or disinfecting liquids especially so when suchliquids are highly volatile, the gum or resin in such instances acting to retard the rate at which the volatile liquids are emitted from the block. 0' The block becomes thoroughly saturated and permeated with the liquid, the excess being expelled during the compressing of the block. Because of the myriad of pores and 5' uid is slowly volatilized from the block, capillary action causin the liquid in the interior of the block to wor outwardly to the surface.-

'take other forms. For instance, a block or mass maybe made from pulp fibers matted or molded together under pressure and. permeated with a disinfecting or deodorizing liquid, or other relatively volatile liquid.

A device such as described may when impregnated with a perfume, be used as a sachet or it may be placed'in the room on a desk, table or the like. Similarly a block impregnated with a disinfectant may be used in toilets and like places.

Where the impregnatedblock is to be used invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

1. A disinfecting and deodorizing device, comprising a porous block of balsa wood impregnated with a volatile disinfecting and deodorizing liquid.

2. A method 'of forming a disinfecting and deodorizing device, which comprises soaking a block of balsa wood in a suitable, relatively volatile liquid and strongly compressing the mass to express the excess of liquid and render the mass porous and springy.

3. A device of the class described, comprising an impregnated block of balsa wood which has been compressed to expel excess impregnating liquid and render the block more porous by breaking down the fibre binding material.

4. A disinfecting and deodorizing device comprising a block of balsa wood impregnated with a gum and a volatile fumigating liquid.

5. A method of forming a disinfecting or deodorizing degn'ce which comprises impregnating a bloclgof balsa wood with a gum and the block to a desir a volatile disinfectin agent and compressing form 'at the same time scribegi I1l1no1s.
