TEE AYEX PRODUCTS CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINoIs cHEmIoL coNrAmEa Application flled September 19, 1928. Serial Ho. 306,859.)

My invention relates to chemical containers and more particularly to containers adapted to retain a chemical which vaporizes when exposed to the atmosphere.,

It is the practice in some instances to em- 'ploy chemical compounds for insecticidal and deodorizing purposes which, when exposed to the atmosphere, will readily evaporate. One of the problems which presents itself in connection with the production of such compounds is that of 'providing suitable `Jcontainers therefor. In order to render the compound satisfactory for shipping or for display purposes, as well as for actual use, a container should be provided which will positively insure the pre'servation of the compound when not in use and which may also be conveniently arranged so as to expose the contained material to the atmosphere when said material is to be used for the purposes lset forth.

AIn general, one of the primary objects of:

my invention' is toprovide a container for compounds of the above mentioned nature which is of simple and economical construction and which will not only permit the compound to be. readily transported or distributed without the slightest possibility of the evaporization thereof,but which may also be readily opened for use so as to expose the compound to the atmosphere.

Another object of my invention is to provide a container or package of the instant nature which includes a moisture-proof and air-proof wrapper for surrounding the com- Pound and a casing 'for enclosing said wrapper, `one portion of said wrapper being 4exposed so as to render the same readily removable when the compound is to be used.

' A still further object of my invention is to provide a container of the class set forth for 'retaining an insecticidal anddeodorizing compound which may be conveniently transported or handled without exposing the contained material to the atmosphere and which wrapper which is impervious to moisture and air, this wrapper being housed within an open 'posed adjacent portion of end casing, and interposed between the compound and an inner surface portion of the wrapper is an apertured plate or'disc, said plate providing an effective reinforcing means for the exposed portion of the wrapper, the outermost surfaceof the disc providing a` display surface, and'the apertures thereof providing effective vents' through which vapors from the contained compound may readily pass.

A still further and more specific objectof my inventionv is to provide a simple and durable container or package for an insecticidal and deodorizing compound in cake form, said container comprising a cylindrical casing which is open at one'end and provided with a closure at the other end, and housed within the casing is a moisture-proof, air-proof, transparent wrapper for encasing 'a cake of the compound, anapertured disc being provided between the end of the cake and the exmeans being provided to permit the container to be conveniently positioned upon a wall or other surface.

These and other objects will be more apparent from the following detailed description when considered in connection with the accompanying drawing, wherein- Figure 1 is a perspectiveuview of a conthe wrapper, and

tainer' embodying features of my invention,

said container being supplied with a chemical compound in cake form;

Figure 2 is an exploded view disclosing the parts which constitute the container disclosed in Figure 1; 1

Figure 3 is a fragmentary central vsectional view taken longitudinally of the casing shown in Figure 1 to more clearly disclose the relative positions of the parts; and

Figure 4 is a view similar to Figure 3 illustrating how the margin of thefiwrapper may be crimped by the magin of`"the'container closure. i

Referring now to the drawing more in detail wherein like numerals have been employed-to designate similar parts throughout the various figures, it will be obvious that a container embodying features of my inventlon is designated by the numeral 10 in Figure 1; This container comprises a 'cylindrical' casing 12, the forward edge of which is provided w'th a head 14. This casing12 serves as a means for housing a chemical compound iwhich, for purposes of illustration, has been di'sclosed in the form of a cake 16. This cake 16 is enclosed within a substantially transparent wrapper 18 which is impervious to moisture and air. In this connection it might be stated that a cellulose product such as the product commonly known as *Celophane, provides a very effective wrapping material. The wrapping material 18 must he impervious to moisture and air in order to prevent the vaporization of the chemical compound and it will benoted that in Figure 3 I have disclosed the cake 16 las being entirely enclosed within the wrapper 18 while in Figure 4 the l:rear surface of the cake is covered by means of a closure member or cover 20.

This closure member 20 is provided with a marginal flange 22 which is adapted to be crimped so as to presenta marginal bead 24, Figures 3 and 4. It will he observed in Figure 4 that this head 24 not only serves as a means for securing the closure 20 to the casing 12 but also as a means for securing the mar- I ginal portions of the wrapper 18 and therehy eflectively sealing the compound within the wrapper. As stated above, in Figure 3 the wrapper 18 completely encloses the cake and hence the head 24 does not engage the mar'. 'nal portions of the wrapper. It will be observed that I provide a suitable fastening member 26 which is formed with an aperture 28. This member 26 is secured between the marginal head 24 and the edge of the casing 12 and serves as a convenient means for supporting or suspending the container upon awall.

Interposed between the forward surface of the cake 16 and the inner adjacent surface of the wapper 18 is a plate or discmemher l30. This disc member 30 is provided with a plurality of marginally positioned apertures 32 and it will be observed from Figures 3 and 4 that the margins of the disc are adapted to be positioned adjacent the head n adjacent forward surface o 18.' As s 14 of the casing 12. When the disc is properly positioned within the container, it will assume a concavo-convex form so that the inner surface of the disc will be s the cakel 16. Also' the outer convex surface ofthe disc will vreinforcingly bear against and support the adj a'cent ortion of the transparent wrapper own in Figures 1 and 2, the outer surfaces of the disc 80 provides a convenient display surface for advertising purposes and the ike, and this surfaceis protected against the transparent wra per. rein orcement for the wrapper 18, the outer surface of the disc provides an attractive advertising medium.

aced from the' 'When the container 10 is to he used, as for example in a chamher or locker containing clothes and the like, the portion of the wrapper superimposing the disc 30 may be conveniently torn or cut away and the container culation vthrough the apertures 32 will he' greatly accelerated. In other words, if the disc were positioned immediately adjacent the front surface of the cake, practically no ventilation or passage of air would take place between the inner surface of the disc and the cake 16. The apertures 32 also provide a convenient means for apprising the user of the volume of compound within the container.-

By providing a container of the type described, the chemical compound may he rigidly encased and secured against vaporization in a very convenient manner. Thus in order to enclose the cake 16 within the container it is only necessary to place the apertured disc 30 over the front face of the cake, place the transparent wrapper 18 over the rear open end of the casing 12 and then force the cake and the disc against the central position of .the positioned wrapper." The marginal portions of the wrapper which extend outwardly from the rear portion of the casing after the cake and disc have been' thus inserted, may be folded toward the center of the cake so as to completely encase the same within the wrapper as shown in Figure 3, or the wrapper margins may he crimped between the peripheral surface of the closure or-cover'20 'as shown in Figure 4. 'When the closure 20 is moved into position, the strip portion of thefastening member 26 may also be clamped in position between the closure and the casing. The marginal -flange 22 of 'the closure is -then crimped in any suitable design and may be conveniently positioned` upon the wall of a locker, closet or 'the like for use. By enclosing the compound within the transparent wrapping material which is lmpervious to moisture and air, said compound 1s msured against lvapor1zat1on when not in use andthe transparency of the wrapping material permits the front surface of the y of the contents within the container and the ters Patent is:

' remov'al of vent through of, said 'disc to be readily exposed to' view. This surface may be employed toapprise the user 'wrapp' g material provides a 'protectiv'e cover for said surface. The disc also provides a very effective reinforcing means to protect 'the wrapping material against being mad- 'Vertently removed or broken. The apertures within the disc permit the free passage of vapors into the chamber in which the container is used and the concavo-convex construction of said disc ser'vs to greatly expedite the free vaporization of the chemical compound.
