CLOSURE FOR AMMONIUM HYDROXIDE CONTAINER Filed Feb. 15, 1955 Wu Q JJ.
United States Patent CLOSURE FOR AMMONIUMI HYDROXIDE CGNTAINER Nicholas E. Kob, Chicago, Ill.
Application February 15,1955, Serial No.'488,342 8 Claims. 1 (Cl. 222 -331).
machines are set up .and operated within a closed room.
Because of the characteristic strong pungent odor of-am- ,monia gas, not restricted the tendency ofthe-gas to escape from ammonium hydroxide is a troublesome one causing considerable.:-discomfort on the part of the operator of the machine.
Blueprinting gmachines are known which 1 include an enclosed storage space for ammonium hydroxide within the machine. The ammonium hydroxide is pumped from theenclosed storage container to thestationl within the machine at which it is employed in the: duplicating process.
However, these ammonium hydroxide containers are customarily-relatively small in capacity and'so must be frequently refilled. Moreover, the containers are not conventionahtypes-which can be removed from the machine when emptyand returned to a source of supply for commercial refilling; As a result, provision of a sufficient amount of'ammoniumrhydroxide' for use in the blueprintingprocess. requires an in'convenient, troublesome,--and time :consuming method of -replaceme'ntof the ammonium hydroxide used upin the process.
The-closure of this invention makes it possible for the firstttirne to store ammonium hydroxide for use in a blueprinting machine in a conveniently reached position readily accessible to the 'machine,'and in the very same carboy or other container in which'the ammonium hydroxide is: delivered by the supplier. The closure is readily adapted to a widely used typeof plastic ammonium hydroxide carboy; In its preferred embodiment it-formsa reliable'vapor-tight seal with the carboy which helps'vrestrict the-ammonia gas present above the liquid ammonium hydroxide against escape into the surrounding atn'rosphere'.- Theclosure cap is threaded to permit it to be conveniently screwed down upon thc neck of the carboy, thereby pressing tightly into the neck of the carboy'a resilient plug fitted with a corrosion resistant feed line and having a discharge outlet.
The invention willbe described in relationto the embodimentisho'wn'in the accompanying drawings. In the drawings:
Figure 1 is a side elevation or one embodiment of. the apparatus of this invention showing-how it may be incorporated witha standard blueprinting machine; and
Figure 2 is a fragmentary sectional view taken along ice 2; a line passing-through the center'of the feed line and exhaust line of the closure shown in Figure '1.
In Figure 1, blueprinting machine 10 is seen from the endof the machine at the right of the operator as he stands in front. of ,work table lliof the machine.
Returning tocarboy 12, exhaust line 19 (made of a corrosion resistant material suchdasstainless steel) extends from a point above the-top surface 200i the liquid ammoniumhydroxide'inthecarboy up through closure 15 to exhaust stack 21 at the rear of the blueprinting machine. Any ammonia gas rising from the liquid ammonium hydroxidewill passthrough exhaust line 19 into exhauststack-IZI, and' from there out stack opening 22 for discharge-into the'atmosphere in the same manner as other noxious gases and .va'pors resulting from operation of blueprinting; machine 10.
In addition, it is seenthat atmospheric pressure operating through stack 21 and exhaust line 19 acts to press down on surface 20-to force liquid ammonium hydroxide out through feed line 13 when pump 16 pulls a vacuum on line '13,
If an exhaust fan is employed in connection with exhaust stack 21, this will assist in removing ammonia fumes that would otherwisebe present in the vicinity of blueprinting machine 10'because'of the ammonium hydroxide. However, it may be desirable to keep the fan inoperative during ,any period-that vacuum pump 16 is drawing liquid ammonium hydroxide from the carboy.
Figure 2 is an enlarged fragmentary view of the embodiment of the closure of this invention which'is shown in Figure '1. The :view in Figure '2 discloses how closure 15may beernployed with a conventional ammonium hydroxide carboy 12 in which commercially available ammonium hydroxide is commonly supplied.
Neck 30of carboy 12 terminates at its upper end in threaded portion 31. Cap -32,'preferably formedof the same plastic materialas carboy 12, carries threads 33 on its interior surface which complement the threads of portion 31 of the container neck. Cap 32 is thus adapted to'be screwed into snug engagement with container neck 30.
Lines: 13 and 19 pass fror'n'the upper face of p1ug'34 through opening38 inrthe top of cap 32. For convenience opening 38 is, in the embodiment shownya circular opening in the top of the cap. It is largefenough to permit the passage ofi-line's 13 and 19 to-vacuum moved from container neck 30.
. 3 pump 16 and exhaust stack 21,, respectively, but small enough that a shoulder 39 remains as the' outer part of the top of cap 32 to press-down upon resilient plug 34 and force it into snug engagement with wall 35 defining the opening of cylinder neck 30: "As shown inFigure 2, the bottom or inside wall of' shoulder 39* may be pro vided with small corrugationsor ridges to improve the frictional contact between cap 32 andthe top of plug 34. Vertical channels 41 are provided on the exterior side wall of cap 32 in order that the cap may be firmly grasped by the hand or a wrench or other tool to be screwed into tight engagement with container neck 30. Any
suitable scoring or marking of'the exterior surface ofthe side wall cap 32, such as is provided by a knurled or roughenedarea, will serve the same purpose.
From Figures 1 and 2 ibis-seen that-a large carboy or other container of ammonium hydroxide may be very conveniently andsafely installeddirectly behind blueprinting machine to provide ammonium hydroxide needed in operationof the machine. A carboy emptied of its ammonium hydroxide may be quickly removed and a full container substituted. 7 t
'As seen from Figure '2; cap 32 maybe unscrewed from engagement with container neck 30, and raised a distance above resilient plug 34. Lines 13 and 19, which are securely grasped .by resilientplug 34, may be grasped to assist in working plug 34 loosefrom opening 35. In addition, pliers or any other suitable tool may be used to grasp the upper exposed portion of plug 34 which rises above opening 35. With. either of these techniques, or a combination, plug 34 may be quickly re- After closure 15 is entirely loosened from the empty carboy 12,. it may be lifted from the carboy, by reason of some flexibility in lines 13 and 19, so that the bottom end of feed line 13 is raised far enough from the'floor to permit it to be slid out of container neck 30 of the empty carboy. The empty carboy is then pushed to one side and a full carboyis slid under closure 15 so that feed lines 13 and 19. maybe inserted into the container neck. Resilient plu g 34, carrying the two lines, is pressed snugly into the container neck opening, cap 32 is screwed down tightly upon plug 34, andv the apparatus is ready again todeliver liquid ammonium hydroxide to vacuum pump 16 from the full carboy.
The above detailed description .of this invention is given for clearness of understanding only. No unnecessary limitations shouldbeunderstood therefrom, as modifications will be obvious to those skilled in the art.
