1 Claim.

The present invention relates to a combination storing and dispensing device and has particular reference to an improved unitary d-emothing package adapted to contain dichloricide crystals which vaporize when exposed to atmosphere.

An object of the present invention is the provision of a moth preventive vapor disseminating device which includes a sealed container for holding chemical crystals for shipment and storage and which when opened and used as a disseminating device confines the crystals in a perforated receptacle part while permitting the escape and dissemination of the vapor element.

Another object of the invention is the provision of a gas-proof container for the preservation of chemical crystals during storage and distribution, which may be opened for instant use and converted into a disseminating device for generating moth preventive and destructive vapors by the attachment of a supplemental perforated receptacle which receives the crystals and holds the same while disseminating the vapors.

Yet another object of the invention is the provision of a drum head sealed container for packaging and distributing chemical crystals, which container may be converted easily into a vapor disseminating device by the breaking open of the drum head and by the attachment to the opened container of a supplemental perforated receptacle, thereby permitting the device to be hung upon a Wall or support while the crystals vaporize and permeate the surrounding atmosphere to exterminate moths and to destroy moth eggs and larvae.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of aunitary package or vapor disseminating device embodying the present invention;

Fig. 2 is an enlarged fragmentary perspective view illustrating a preferred embodiment of the device with parts broken away and with parts in section showing a supplemental receptacle affixed to a filled distributing container;

Fig. 3 is a fragmentary view in section of parts of a closed friction top can adapted for use as the distributing container element of a modified construction; and

Fig. 4 is a fragmentary view in section of the modified form of vapor disseminating device illustrating a supplemental receptacle part inserted into the opened distributing container of Fig. 3.

Referring to the drawing, Figs. 1 and 2 illustrate a preferred embodiment of the present invention and show as a part of a vapor disseminating device, a storage and distributing container I l. This container is fully described in the W. M. Holloway, United States Patent 1,980,995, issued November 29, 1934. i

The container ll comprises a cylindrical sheet metal body E2, closed by a bottom end 13 double seamed to the body in an end joint M. The opposite end of the container is provided with an outwardly extending stop bead I5. A wall H5 at one side of the stop bead merges into a friction wall 21 extending parallel to but spac-ed from the body. This friction wall joins into a wall it which merges into the upper cylindrical wall section of the container as at I 9.

A frangible seal or drum head 2!, preferably of a cellulose material which is impervious to both gas and air, has an outer edge 22 incorporated in and secured to the upper part of the con tainer wall. The upper edge of the wall I9, is curled inwardly at 23 to provide this joint and the impervious drum head thus makes a suitable seal to prevent deterioration of the chemical demothing crystals, designated by the numeral .24 which are sealed in the container.

A series of interrupted threads25 are'formed in the body by being outwardly pressed inthe wall I9, intermediate the friction wall I! and the curled edge 23 of the container. The threads 25 extend a relatively short distance around the circumference of the can body, each thread arranged at an angle relative to the upper curl edge 23.

An outer screw closure may be provided to cover and protect the drum head 2! at the upper end of the container body under condition of distribution and storage. Such a closure if used would be threadedly secured to the container by utilizing the threads 25 of the body.

A supplemental receptacle 26 is a necessary part of the disseminating device and since this serves the same protection as a separate screw cover for the distributing container, the screw cover will preferably be eliminated. The receptacle 26 therefore is affixed to the container II and both parts are distributed as a unitary package to the ultimate consumer.

The consumers first step, in preparing the disseminating device for use, is the removal of the cover if an outer screw closure is present or the removal of the supplemental receptacle 26 tion ring 44 as by an end seam joint 45.

when such a receptacle is a part of the package. The next step is to break and remove the frangible seal 2|, from the sealed container thus opening the sealed container. The supplemental receptacle 26 is next secured to the crystal containing or distributing container into its disseminating position. The unit is then inverted into the position of Fig. 1, the crystals 24 falling out of the container H and into the receptacle 26 until the latter is filled. The device is now ready for use and as the crystals vaporize and thus become smaller other crystals from the container above drop down and maintain the supplemental receptacle filled.

Receptacle 26 comprises a metal cylindrical body 2'! which is perforated at 28 to provide a plurality of openings extending throughout its a perforated end member 32 in an end seam joint 33.

Figure 2 of the drawing shows the supplemental receptacle 26 as being aflixed to the filled distributing container H at the time the container and receptacle are first received by the ultimate consumer. Such an attachment is made by the interengagement of the interrupted can body threads with similar threads 34 formed in the connection 29. The threads 34 are also at an angle relative to the edge of the connection and are pressed inwardly at spaced intervals in a flange wall 35 of the connection 29.

In order to conveniently hold the disseminating device in its inverted position (Fig. 1) provision is made for hanging it up. A suitable fastener 36 is secured to the end member l3 by means of a rivet 31. Such a fastener may be a flat plate resting directly on the end member, as illustrated by a dotted outlined portion 38 when the container is being stored or distributed. An aperture 39 is formed in the fastener 36 and when the unit is to be hung up for disseminating the vapors, such a plate may be bent. up at right angles and shifted on its connection into the full line position of Fig. 1. A nail or screw on the wall may then be passed through the opening 39 and slid into a slotted extension 4| having a width too small for the passage therethrough of the nail head. This prevents the device from becoming detached from its support. Such a device may be hung conveniently upon a closet wall, door or shelf where vaporization of the chemical crystals will be desirable.

Figures 3 and 4 of the drawing show a modified form wherein a friction top closure can 42 is used as a distributing container. A container body 43 has secured to one end thereof a fric- The container 42 is closed by a usual type of friction plug closure 46 (Fig. 3) which is inserted into the ring member 44 to seal the container for preserving the chemical crystal contents.

Upon removal of the closure 46 from its sealed position the container is ready to be converted into a disseminating device. This is done by the insertion of one end of a supplemental receptacle 4! (Fig. 4) into the friction ring 44.

The supplemental receptacle 4'! (Fig. 4) is similar to receptacle 26 (Fig. 2) and includes a tubular body wall 48 which is also perforated, as at 28, to provide a plurality of openings extending throughout the cylindrical surface. One end of the supplemental receptacle 4! is closed by a perforated end member 49 which is secured to the tubular body 48 by a usual type end seam joint 5 I.

The end of the supplemental receptacle 4'! which engages with the container 42 is open and the edge of the body wall 48 at this end is curled inwardly as at 52. An annular outwardly pressed bead 53 is formed adjacent the curled edge 52 and provides a shoulder 54 or stop on the outer surface of the body wall 48. This limits the degree of insertion of the receptacle into the friction ring 44. The outer annular surface of the receptacle wall which is located between the curled edge 52 and the shoulder 54, designated by the numeral 55, is preferably sized to provide a snug friction fit within the ring 44 of the distributing container 42 (Fig. 4). This holds the supplemental receptacle 41 in proper cooperating position with the container 42 so that it will receive the crystals from the container after the device is inverted for use. Thus the two connected parts of the package provide a unitary insecticide vapor disseminating device.

A similar tab member 35, as illustrated in Fig. 1, may be used to hang up the inverted device and may be secured to the bottom end of the container 42 in the same manner.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
