(01. 221-60) .- This invention relates to, closures for. contain.- ‘ vorder to remove the contents of the'container,' ers, more particularly to closures for collapsible‘ and the cap can therefore not be lost or mislaid. My invention is hereinafter more particularly . tubes. . The well known screw cap for containers has 5 long been recognized as being objectionable be described and is illustrated in the accompanying drawing in which: ' ' 5 - cause of the fact that the cap is easily lost or " “ Fig-1 .is'a plan view partly broken away; misplaced, and a good deal of trouble is involved in removing and replacing the cap. ' A good many efforts have been made to overcome these objec 10 tions, but most devices for that purpose have not been practical because they have either not pro vided an air tight seal or'because the cost has been‘ prohibitive. Containers'are sold inlarge 'quantities at a small margin of profit, and the 15 , addition of a fraction of a cent to the cost of manufacture is an important item. , ._ ~ The object. of my invention is to devise a closure which‘may bemreadily opened and closed without removing the cap and which will provide an air tight closure without the useof washers, and which maybe manufactured at a cost at or below the cost of the ordinary screw cap. I attain this object by forming the exterior of the discharge and of the container with slots or recessesform 25 ing'shoulders in two opposite vsides adapted to be engaged by the inturned edges of the ?ange of a slide. The sides of the discharge end above the shoulders may be tapered Fso that the slide may be snapped over the topof the discharge end. 30 The top of the discharge end is preferably slightly ' convex to provide complete and full engagement , between the cap and the top- or mouth of the opening. A hole or opening is located in the slide cap adjacent one end thereof and adapted to 35 register with the opening in the discharge end vof the container. Other objects of my invention and other details and modi?cations of my con structicn will hereinafter appear. . The construction above described has'the fol 40 lowing advantages: 1 1. It avoids the necessity of threading the neckv of the opening of‘the container. ‘ modi?cation of my invention; ' Fig. 5 an end view partly broken away of an; other modi?cation of my invention; 4 -' \.

No change in size or shape of the container, ‘or the package or carton inv whichthe container is packed is required when using this type of _ closure. . ' ' _ 5. The cost of manufacture is much lower, than the cost, for instance, of bakelite caps now corn . ‘monly in use. 55 ' 1 - 6. It is ‘not necessary to remove the cap in engagement with the said slots 3., 3.'is slidably ' mounted on the said discharge end, thesaid in-. turned edges lb, 4" bearing again'stthe upper walls of said slots 3, 3~which form shoulders, and 50 the under surface of said slide 4 engaging the upper surface or top of the said discharge end _I. The slide cap 4 is formed of resilient material, preferably copper vor brass or a non-corrosive _ metal, and the height of the depending ?anges 55 2 " . . 2,061,798 4', 45 is preferably slightly less than the vertical in vertical cross-section, as illustrated in Fig. 4, distance between the upper edge or shoulder of ~whereas in the other ?gures the slots 3, j are the slots 3, land the plane of the top of the substantially rectangular in cross-section form discharge end I so that when the inturned edges. ing a squareshoulder at the upper side thereof. 4'’, 4b of the depending ?anges 4', 4* engage in Another form of depending ?anges 4' is il- 5 - the slots 3, 3 the slide 4 is under compression and lustrated in Fig. 5. in this construction instead bears against the top of the'\ discharge end I ' of the substantially- vertical ?anges illustrated in forming a tightclosure. It is important that the other ?gures the ‘flanges 4“, 4" are ‘curved the difference in height of "the ?anges and the or arcuate in vertical cross-section, and the ends 10 distance between the slotsand the top be not ‘4b’, 4b’ of the ?ange engage the grooves 3, I. 10° - too great, otherwise the slide will be under ex? ‘ ,As shown in Fig. 6, the discharge end I may be cess compression which will make it di?icult. to move and may cause contortion of the slide which formed of two parts, I'and lb, the part II’ being will prevent it from ?tting tightly against the threaded at its upper end, and the part I‘ having a circular central opening 5 and being internally 15 threaded at its lower end for threading on the 15 top of the discharge end at all points. ‘ Preferably the top of the discharge end I is slightly convex in a vertical section taken at right angles to the grooves 3 and straight in a vertical section taken parallel to the grooves 3. 20 This slight rounding of the'top permits a more effective engagement of the slide cap 4 with the top of the discharge end I. With this construc tion the height of the ?anges may be substan tially the same as the distancebetween the shoul cylindrical and secured to the container v2, and upper end of the part I". The part IP‘ is other wise formed in the same general way as the dis charge end I as illustrated in Figures 1, 2, and 3;’ being substantially square’ in horizontal cross- 20' section. Instead of a slot 3 forming shoulders for engagement by the inturned edges 41’ of the slide cap 4, a recess, 3' is formed in opposite sides of the part Ia, forming shoulders for en 25. ders and the top, the tension being caused by ‘ gagement by the said inturned edges 4“, 4b.v .hiihe rounding or convexity of the top. The opening 5 in the discharge end I is prefer ably round in horizontal section, and at one end of the slide cap 4 is an opening 6, which may, 80 be the same shape as the opening 5 in the dis charge e?d I, and which is‘ adapted to register with said opening 5‘ in one position of-the slide cap-4. The opening 6 may be smaller and of any desired shape, as illustrated in Fig. 10' or Fig. 11, so that the contents may be expressed as a ribbon of any desired shape, inthe case of paste. The opening 6 may be merely in the form of a recess, as illustrated‘inFig. 12. At the ends of the-slide cap 4 are lugs ‘I, ‘I which are'adapted to engage the discharge end I to prevent the .slide from being removed. The lugs. ‘I, ‘I may depend from the top of the‘slide 4 as illustrated in Fig. 2,, or may be turned in wardly\on the ?anges 4*, 4a asillustrated in Fig.9., '. ~ . ,. ' 25 Although theslide cap 4 will be pressed ?rmly upon'the top of the discharge end I under com pression by the ?anges 4“, _so that there will’ be - a frictional engagement and the slide will not move unless force is applied thereto, as an addi- 30 tional‘ precaution against movement of the slide while the article is in transit before it is used, the hole 6' may be only partly punched out as illustrated in Figs. 7 and 8, leaving a‘disk of metal 8 in the opening.- This is punched below '35 the lower surface of the slide 4" so that it wwill engage the’ top of the discharge end I_ when .the slide is moved, and at one edge of the disk 8 a lip 8“ is raised slightly above‘the upper surface of the slidev 4,” so that a-flnger nail, pin or other 40 pointed article may be inserted beneath the said lip to remove the disk 8 when it is desired to use the device. - ‘ 3 / Although it is contemplated that a tight clo sure will be obtained by the (device as described, 45 as an additional precaution against leakage, par The slide cap may be applied to thedischarge \ '\end of the'container by forcing it on from one ' ticularly before the contents of the container are side thereof and subsequently bending the lug ‘I » put in use, a frangible seal ii of paper or similar to prevent the removal thereof. However, it is materia maybe inserted in the container 2 be an‘ important feature of my invention that the low the discharge end I, as illustrated in Fig. 8. 50' slide cap 4 may be snapped on from the top of Such a seal may also be ‘placed across the top the discharge end by“, placing it over the end ‘ ‘of the discharge end Inbefore the slide cap 4 is and pressing it down. The outward slope of the discharge end I causes the ?anges 4‘; 4' of ‘the slide cap *4 \to be pressed outwardly until the inturned; edges 4”, 4b slip into the slots 3, 3. The distance between the upper 'edges or shoulders of the slots 3, 3 is preferably slightly greater to applied thereto, orig.‘ thin metal disk may be formed in the ope in the discharge end as is commonly done in other types of closures. As 55 shown in Fig; 13 the°top of the discharge end I may be notched or rabbéted around the opening 5 and a washer I0 located therein. This washer.‘ ‘than the normal distance between the ?anges “ may be annular as illustrated, or may be a disk 4', so that _when the cap is in position on the discharge end the ?anges v4*, 4' bear against adapted to be‘ broken when it is desired to use 60 the contents of the container. , the said shoulders.

It should be noted that when the lug 1 forms part‘ of or is secured to the top of the slide cap 4, it has a sti?ening e?'ect tending to prevent the 3 shoulders on opposite sides thereof spaced from and substantially parallel to the ‘ plane of the top, and a slide cap‘ having a scored, partially severed disk in the-top thereof adjacent one end adapted to register withthe opening in the closure, and ?anges depending from the two top/of the slide from bending and tending to keep ' opposite sidesthereof, ‘said ?anges being sub- . it in close contact with the top of the discharge stantially parallel in their longitudinal direction end ‘I.
