v body portion `thereof and provided with capping and sealing means in connection with said nozzle. v

Cans, containers, or receptacles as used for lacquers, varnishes, paints, solvents, thinners, oils,` and other liquid-containing articles, Aare generally provided with a nozzle portion and cap attached thereto extending from the body portion of the can. Often'times such cans, containers or receptacles leak because the nozzle portion has: structural defects in connection with the capping portion. These defects are often so serious that when the iilled cans are being transported from the factory to the dealer or consumer direct the liquid leaks'therefr'om because of the rough handling and managing during shipmentV causing considerable loss of material.

It is a general object of this invention, therefore, to avoid the aforementioned defects.

Another object of lthis invention is to provide vide a simply constructed container having clo-` sure means which initially requires tool pressure to close the same againstthe container and which subsequently is easy to removeand still maintain an eiective leakage-proof seal when subsequently used in connectionvwith the contain'er.

One further and particular object of this invention is to provide a container With-a nozzle having discontinuous circumferential grooves which also extendr partly longitudinally therefrom toward the free end of the nozzle, a cap, and means intermediate the cap and nozzle and a sealing member covering the peripheral portion of the-cap and also the nozzle'for preventing loosening of the capor tampering with the same n until the time when necessary for the use of the liz Cil

contents of the container. y

With the above and other objects and features in View, theinvention in its preferredembodiment includes a container with a nozzle extending therefrom having a plurality of staggered discontinuous grooves on the periphery thereof, a Vcap adjustably mountable on the nozzle, a disk member intermediate the nozzle and cap for covering the nozzle endand a sealing unit or member combined with the cap for preventing tampering of the cap or nozzle vbefore the sale of the container.

The invention furthermore consists in the newA and novel features of the construction and the arrangement of the parts hereinafter described (ci. 22o- 40) in connection with the accompanying drawing andas more particularly setforth in the appended claims.

Similar reference characters designate` corresponding parts throughout the various views.

Referring to the drawing, the preferred illustrated embodiment includes a metallic receptacle container or can 15 of elongated shape, although any forni is suitable. The can at one end contains a nozzle 16 which is integral with or Welded or joined to the top of the can 15. The nozzle, being cylindrical in section, has an upper portion with indentations of smaller diameter for permittingproperV adjustment thereon of the capping and sealing means hereinafr more fully described. Thef difference in diameter is due to the depressions formed in the nozzle to obtainthe present embodiment.

The nozzle -16 contains a peripheral annular bead 17 above which 'are set a plurality of discontinuous circiunferential recesses or grooves 18 in the face of the nozzle 16 and substantially parallel with the bead. Intermediate each recess or groove 18, the peripheral face portion `19 of the nozzle is substantially contiguous with the part 20 beneath the bead 17 to afford a smooth backing for a cap 2l.

The recesses or grooves 18 are formed by mechanical pressure, such as by a punch press, against the exterior of the nozzle, at definite parts of the periphery thereof. The depth of said grooves 18 is such as to accommodate the engaging means of the cap 21 and one portion, namely, the forward peripheral-portion 22 is of slightlyless depth than the other portion 23 in each groove, as shown in Fig. 4 of the drawing.

Extending at an angle from the discontinuous e grooves 18 are the longitudinal grooves 24 which are punch-pressed or formed from thefree end of the nozzle 16 to the discontinuous groove 18. The depth of such longitudinal grooves is the same as the deeper portion of each discontinuous groove 18 above the bead 1'7 and merges with it to permit easy sliding of the cap 21- along the longitudinal grooves before engagement. It will be noted that the grooves in the nozzle are set in staggered and spaced apart relation with each other on the periphery of the nozzle portion above the bead 17 so as to afford a symmetricalconfiguration to the nozzle. Furthermore, as shown in Fig. 11, the sectional outline of the longitudinally extending groove vis straight so that it is substantially parallel with the part 20 of the nozzle below the bead. The outline, as shown in Fig. 10, illustrates the configuration of the discontinuous groove 18 with respect to the bead 17 and end portion of the nozzle. TheY grooves are of substantially the same depth as the bead 17, while the intermediate curved part 24 extends further outwardly than the end 25 ofthe nozzle..

26 with its upper portion 27 milled to prevent;

undue wear on the peripheral surface thereof and also to provide easy grasping means for permitting the cap to be engaged onto or disengaged from the nozzle 16. The lower or unmilled portion l28 of n wall 26 is provided with a plurality of Y inward radial depressions 29 set at spaced intervals.VV Such depressions 29 may be formed by any well-known means such as a punch press and are of a depth sufficient to permit easy sliding over thelongitudinal grooves 24. The depressions 29 are set at the edge of the peripheral wall 26 and n for purposes of illustration are shown straight or perpendicular to the lower portion 28 of the wall, although they may be slightly tilted to permit greater hugging action in the grooves of the nozzle. Each depression 29 when viewed from the exterior, asshown in Fig. 8, shows the peripheral wall 26 bent and curved inwardlyl and then downwardly toward the axial center of the cap. Thence, the bent portion 30 ofthe wall continues downwardly at an incline to the peripheral edge 31. The edge 31 of each depression ends short of thedepending peripheral wall and as such provides excellent anchoring or engaging means. One end 32 of the depression edge meets with the edge of the peripheral Wall 26 and forms a ridge or incline so that upon screwing the cap 21 on the nozzle a tighter fit is effected at that portion with the discontinuous grooves 18.

The depression as illustrated in Fig. 7 shows a contour 33 similar to the grooves 18 for effecting a flush contact to retain the cap 21 in engaged position on the nozzle 16. In the instant case four depressions 29 are shown in the wall 26 but merelyk for purposes of illustration only and they correspond in number with the grooves 18 and 24 in the nozzle 16. These depressions 29 of cap 21 flt loosely Vin the longitudinally extending grooves 24 to permit easy setting of the cap. on

the nozzle, but make a close fit with the circumferential discontinuous grooves 18, as shown in Figs. 2and 4. The slightly raised face portion 23 of the groove 18 permits better contact with the depressions 29 of the cap. p l

It will be noted that the depressions or tongues 2x9 `are-located at the lowermost edge of the peripheral wall or flange 26, whereby the largest possible yieldability and resiliency is obtained.

lowermost edge portion bent over the lower-part of the shoulder of thev nozzle, as shown in Fig.2.

Upon ripping olf the member 39 the outer sealing cap is readily removable, and then the cap 21 by reason of the relationship just described acts as a secure closure when the container is in use,

nevertheless permitting yready removal of the cap 21.

Inside'the cap 21 is a resilient disk member 34 setagainst the top wall thereof whereby to provide a leakage-proof contact with the inbent or ducked portion 25 of the nozzle and prevents the escape of any of the contents from the-container 1,5. The shape of disk'member34 corresponds with the circumference of the cap` and forms a snug t against the inner face of the peripheral wall 26. 'The disk member 34 may be of any resilient material such as compressed paper, ber or cork having a metal foil on its :sol

under face portion facingthe end of nozzle 16 to make contact with the inbent end'25. lThe member may be made coated to prevent being soaked by the contents. It is to be Inoted thatthe y resilient disk member 34 Vis compressed more tightly against the nozzle by the cap 21 as it is being engaged onto the nozzle, and when the cap is first engaged with the nozzle, extra` or` tool pressure must be applied at the milled portion.

26 to form an annular groove 36 on the face of the disk in contact with the nozzle.

With the diskmember 34 in the c a'p the de-` pressions 29,.,slide easily .into the longitudinal,-

grooves 24 of the nozzle and make contact rwith the portion of the circumferential discontinuous grooves 18 merging with the rst-mentioned grooves. However, upon further turningthe-cap clockwise against the nozzle,a little resistance is encountered due to the disk member 34being compressed between the cap 21 and the inbent portion 25 of the nozzleand* also because of v the slight rise of the part 23 of the circumferential groovel. Furthermore, movement of the cap causes'the `formation of a permanent annular peripheral groove 36 corresponding in depth withY the length ofy turn of cap 2l.` The peripheral groove thus formed effectsa leakage-proof closure with the nozzle end so as to p-revent any escape ofthe contents yfrom the container. this manner, also, the cap is maintained securely Once the permanent peripheral vgroove hasbeen formed in the disk member 34 it is not necessary to use tool' or extra pressure` whenever *cap-V21A 15l tion the detachable outer'sealing cap 39 has its nozzlel 16 for closingr forth has a centrally depressed top' portion 3'7` for permitting the insertion of grasping means between said portion and the. strip 38 of an annular sealingv member 39. The latter member has part of its topportion cut away to provide a recess for theinsertion of the fingers or other means between the underside of the strip 38 and the depression 37 of cap 21. The annular member 39 has a semi-circumferential top extending flange portion 40 at the `recess portion merging into the-half top` face portions 41` and 42 so as toprovide a rest on the cap .21.

The strip 38 is joined Ato the sides of the top face portions 41'and 42 yby means of the thin strip like connections 44 and 44 respectively,4 while the lower'end of the strip is joined'at the top of the peripheral wall 43 of the member by means of the connections 45 and 46 respectively. Intermediate the strip 38 and the side portions' 4l and 42 are the cut-outs or grooves 47 and 48 respectively, while beneath the strips 45 and 46 arevthe converging slits 49 and 50.

It will be noted that'the'strip 38 extends. to andA merges with the peripheral Wall 43 and is separated therefrom by the small converging slits above mentioned. The sealing member 39 as a whole is of relatively thin metal and strip 38 is such as to permit easy separation from the side portions 41 and 42.

The peripheral wall 43 of the annular sealing member 39 extends down over the peripheral wall i of the cap 21r and the beaded portionA 24 '-of nozzle `is crimped inwardly against the annular depression 17 forming a seal-as shown in Fig; 2 to prevent .tampering with or loosening of the 'cap and thus the loss or substitution of anyliquid in container 15. v

When it is desired to remove the contents from' the container, the endof strip 38 is grasped and pulled free of the side strip connections 44 and 44 and the strips 45 and 46 abutting the top of peripheral Wa'1l743. The pulling onthe'strip is continued until it is torn free of theperipheral wall, thus cutting apart the annular member 39 which springs loose of the cap 21. The cap then is `ready for disengagement with the nozzle. and

removal of the contents from the oontainer'may ing connection is obtainedkwhich iseffective against leakage or tampering. The discontinuous grooves of the nozzle are in connection with grooves extending angularly therefrom and pro-l vide means for retaining the radial inwarddepressions on the cap. Ihe grooves are formed to provide an efficient and non-leakable nozzle end when engaged by theVcap. WhenA the cap containing the disk member is first used in connectionwith the nozzle, extra pressure is required to effect proper closure toiform aleakage-proofi seal. The engagement of the cap with-the nozzle sets" the disk member-.within the cap and also adjusts it so that said disk member will be easily accommodated against the end of the nozzle and form a circumferential groove corresponding with the nozzle end. Also the depth of a portionof the discontinuous grooves being slightly less than that of the depressions on the cap, permits a relatively tight engagement therewith. The gro-ove once formed in the disk member is permanent, and needs no further extra effort to put the cap on the nozzle. The annular seal member surrounds the periphery of the cap and also aportion of the nozzle to prevent leakage, opening, o-r tam-` pering with the container. It will have been seen that the invention is the improvement in a 'metallic container consisting o-f a nozzle having a plurality of peripheral discontinuous grooves ter` minating in grooves longitudinally of the nozzle, and a cap having a vplurality of lradially inbent depressions forming tongues for effectively engaging the longitudinal grooves of the nozzle and upon turning of the cap the peripheral grooves' engage the tongues thereof. The iriben't portion of the nozzle at the longitudinally.` extending grooves is smooth to permit easy passage therei along o-f the tongues in the cap; The invention also includes the tongue members being slightly tilted Awith respect to the peripheral grooves to secure a greater locking action.' Also it includesV in the combination thereof a yieldable di-sk to secure complete interior sealing of the nozzle and cap with respect to each other, and `finally the invention includes the provision of a specific external sealing member which may or may not be applied to the other partsspeciiically embodied in the invention.`
