INsEcTIcIDE DISPENSER Filed Ju1y`25, 1945` INVENTOR.

WILL/2M .L ,Qassam/SR heretofore stated r This invention relates to insecticide :dispensers and particularly to jlevi'ces' adapted to contain :and dispensegpoisonous liquid insecticides.`

ffl- Insecticide"dispensers heretofore known" are objectionable fora number of reasons. 'I hey resimpleand efficient container and dispenser; a

vdevice adapted to storerthe insecticide and to be airtight and leak-proof until the dispenser kis put into operation; in which the dispenserfis put into dispensing condition-by merely rubbing it on an: abrasive surface without the aid of any tool, and without contaminating the hands of the operator; and whichcan be placed in any `-desired positionv and be moved to another 'location' without having the insecticide come into contact with thehands `of the user.` y f Some of theipoisonous solutions commonly used as insecticidesare'sufciently potent to kill pests bycontact. Naturallyiit vis-desiralole to avoid infjry to the ngers and hands of the user by con'- tac'trwith such`solutions`.' Arsenic, a common ingredient in these solutions, is known by themedical profession to be one ofthe causes-o herpes 'zostergi Consequently, an important feature of my inventionvis thefact that' the user does not need to comev into contact with'V the solution nor to handle the dispensing portion of the container,

either before or after the dispenser has been put into"operation.` V

Thedispenser is so constructed-that a plurality o'fffeed ropeningsar-e provided by merelyrbbing the dispenser on an abrasive' surface'suclfr "as a concrete w'alkior brick Wall. The size of thefope'nings may be varied. Thus the user may control the speed of iiow ofthe solution,'and may increase it-'byincreasing the size of the openings by rubbing the dispenser on "an abrasive surface, vas

l Another advantage of my invention is the construction which permits' the device'to emptyitself ataV desirable rate'of speed forits intended purpose.` A further advantage results from the nume ber-- and: location lof fthe feedopenings', and"th'eir availability to "the pests 'intended to come contatwith or tof-eat the insecticide.

Fig. 4 is an elevational' View of thecontainerdispenser fin its` inverted;y operativelposition.

Figs. 5 and 6 are vertical sectional views of ,the dispenser details, onlanenlarged scale, taken in the planes `ofthe d'vclittedv lines 55`on Fig. 1 and Iii-f6 onFig. 3, rs`pectiv`ely.'` In that embodiment of the invention shown in the'drawingsgthe container is indicated asfa whole at I v(I and`the combination closure capand dispenser at II. The container I0 preferably is made of-glass or other suitable material, and` comprises acircular-,at ,bottom I2, cylindrical side walls I3, a circumferential ribl I4 and screw thread I5. The open end of the container Illis closed bythe screw cap Iliwhich, preferably,fis made of metal,A and comprises a top I6 andscrew threadedskirt vI'Imadapted to engage the thread I5-on thecontainer, I0.I vThe lower` edge of the skirt I'I may be providedfwith a Ibead I8. l

f The top fI-6; of ther combination' closurecap anddispenser,;as shown in Fig-1,` is provided with aplurality o frraised members I9, preferably three inlnumbenf yThese protuberances I9 are ap,- proximatelyconeA shaped and areiormed'in `the top lI-Ii bypressing the, metal outwardly from the' insideofthewcap by theaid off any suitableztool Pressing of themetal outwardly. to form the pro-V tuberances lil'fresults in spreading the metal and reducing its thickness and consequently the metal of thesme'mbers I9,.particularly` at land near the apex" of -=`the-cone, is-relatively thin! Thisisindicatedat' I9" inLFig.' 5, where the thickness Aof the metal intheiupper partofwthe cone' portioni's less than that of the at part of the top I6; 'While the reductionof the thickness :of the metal in the members -I9iis1incidental to the forming of said protuberances, it is a desirable and valuable feature of my invention for the reason that it facilitates the forming of an opening 20 in the apex of each member I9 for the purpose of dispensing In the form of container and closure meansv shown in Figs. 1 and 3, I preferably use a-washer 2| which maybe in the form of a disc or a at ring. Its peripheral portion is loeatdfbetween# the upper edge of the containerlandthefinner.

flat surface of the cap top I6,l where'it forms 'a 4 full contents of the container I0 will be dispensed without waste. The construction is such that the device can be handled and moved, even after having been put into operation, without contaminating the hands and iingers of the user. Sometimes insecticide solutions become increasingly viscous and clog the dispensers. In prior art constructions this necessitates handling of contami- Thatedparts, .use .of tools .topryroiclosure memjfbers, to .renew wicksf or, `punch` openings', and other inconveniences, whereas in using my device the dispensing openings 20 may be enlarged by merely taking hold of the clean, inverted conv-'lt'ainferllll and rubbing the protuberance I9 of the ,cap topdfonian abrasive surface. l Changes may be made in the form and size of :the vseveralparts-and in the details of construcseal and prevents leakage of the insecticidesolw' tion. If a disc Washer'` is used, or if the ring washer-is of suflicient yradial-width to underlie the raised members vrI 9, lipre-fer-tof-indent the washer also fgfrom the inside of Vthe cover, as indicated.'` at 22, so that the washer conformstothecontour of the inner surfaces of the cover i6 vand members 4,9. ,'Ihefwashe-r `llxrnayybe madeV of paper or other absorbent :material which i aids in `feeding theinsecticide solution gradually .to the openings .2U-inthe members i9. However, it is-to be understood that the use of a washer may be dispensed with,as-I prefer to do .inthe .form ofconstruction shown in Fig.,2, v ,t Y

In`this,lor1'n of construction, vI prefer toiluse Asome sealing` material such asa coating of gum' applied to Lthe inner surface of the skirt 23"'above theibead 26,4as'indicated at ,21, in lieu of the washer 2|.
