CAP 0R cLosuRE FOR CONTAINERS 0R TUBES Filed oct. 28, 1957 alfanum,
CAP OR CLOSUR FOR CONTAINERS OR TUBES .Nathan B. Lerner, Chicago, Ill., assigner to W. `Braun This invention relates to a cap or closure for containers, tubes, and the like.
One of the objects of this invention is to provide a cap or closure for containers which may be positioned on the neck of the container to seal the discharge end of the container and prevent discharge of the contents thereof, and which cap or closure may be positioned to permit the contents to be discharged through said closure or cap.
Another object of this invention is to provide a container closure manufactured from resilient and llexible material which may be used without a sealing `disc or liner and which is held in captive relation to the container .but `which may be moved to seal the discharge opening of the container to prevent the discharge of the container contents and whichv may be moved in relation to ,the container to unseal the discharge opening and permit the container contents to be discharged through said container closure. l
Another object is to provide a container closure integrally molded lfrom resilient and flexible material provided with internal threads which engage the threads on the neck of the container in such a seal tight t relationship as to prevent the container contents from ever passing through the engaged threads.
Another object is to provide in combination a container having a threaded neck portion and a closure or cap having an internally threaded portion in engagement with the container neck, in which the cap is held captive to the container neck but which is provided with means permitting the container contents to be discharged through the closure, and in which either the threaded neck member of the container or the closure member is formed of a -resilient and exible material with the opposite member having a threaded portion formed of rigid material so as to permit engagement of the threads between the-two members in a seal tight fit to prevent the container contents from ever passing through the engaged threads.y
Another object of this invention is to provide a capor closure for a conventional tube containing paste material which is held captive to said tube at all times and provides a covering for the discharge end of the tube but which may be positioned to either seal the tube discharge opening and prevent the discharge of the paste material or to unseal said discharge opening and permit the discharge of the' paste material through said cap or closure.
Closures or caps now used to seal or close the tubes of tooth p-aste and other containers are completely removed from the neck of the tube or container to expose y the discharge end and while thus removed become lost or become unsanitary due t-o contamination with their temporary placed position. Furthermore, the discharge end-of the `tube or container is completely uncovered and exposed, also resulting in an unsanitary condition. With this invention all of the foregoing objections are elimi- `nated in that the cap or closure is held captive `to the tube or container yet may be positioned inV relationto the `discharge end of the tube or container to seal or unseal United States Patent "ice the discharge end and permit the paste or other material to be discharged through the cap or closure when in unsealed position without exposing the discharge end of the tube or container. The cap or container of this invention may be economically and eliiciently produced and applied at a cost no greater than the present day caps or closures.
Other objects will become apparent as this description progresses.
In the drawings:
Fig. 1 is an elevational view lof the cap or'closure of this invention applied to a toothpaste tube.
Fig. 2 is 4an enlarged top view of the cap.
Fig. 3 is a cross-sectional view taken on lines 3-3 of Fig. 2, showing the cap in elevated position to permit the v contents of the tube to be discharged.
Fig; 4 is a view similar to Fig. 3 but showing the cap in closed position to seal the discharge opening of the tube to prevent discharge of the tube contents.
Fig. 5 is an enlarged elevational view takenl from the rear of the discharge end of the cap.
Fig. 6 is a cross-sectional view showing a cap or closure with a modified form of discharge spout.
Fig. 7 is a plan view taken on lines 7-7 of Fig. 6, and
Fig. 8 is a cross-sectional view showing a modified form of construction in which the container neck is provided with an annular shoulder for holding the closure in captive relation.
The structure shown in Figs. 1 to 5 will be lirst described. The cap or closure, generally indicated at 10, is molded preferably of a resilient plastic material, such -as polyethylene, plasticized nylon, plasticized acrylic resins, plasticized vinyl resins, and-the like, andis adapted to fit over the neck of any conventional tube or container containing material to be dispensed. While the invention is illustrated in connection with a tube it will be understood that this invention is equally applicable to other types of containers formed of glass, plastic, or the like, for containing liquids and other types of materials to be dispensed.
As illustrated, the conventional tube or container generally indicated at 12, has a neck portion 14, a portion of which is provided with a helical thread 16. The neck above and below the threaded portions are designated at 18 and 20 respectively and same have a smooth surface, notbeing threaded. The neck is'provided with a discharge opening 22 communicating with the interior of the tube through which the contents of the tube are discharged. The tube 12 just described is conventional in the art and no invention is claimed therein.
The cap or closure 10 forming this invention is adapted to be applied to the neck of the tube so that once attached thereto it is held in a captive relation thereto, that is, it m-ay be rotated with respect to the neck for opening and closing the discharge opening 22 of the tube but may not be separated from the neck. The cap or closure comprises a tubular body portion 24 having a gradually inclined wall 2-6. The lower or skirt portion 28 of the cap flares outwardly from the body 24 of the cap. The body 24 has an internal helically threaded portion 29 and the internal wall of the skirt portion adjacent the mouth thereof is provided with an annular bead or ring 30, providing a smooth internal space or surface 32 between the lower end of thread 29 and the ring 30. f
. .Extending across the body 24 at the top thereof is a aseo-,sos
3 said sealing portion 38 having a line sealing contact with the inner edge of the neck 14.
A portion of the annular wall portion 40 hasua slot 42 which communicates with a rectangular@shaped` duct 44 formed by molding the cap to provide an innervertical wall 46 and an outer spaced Vvertical wall 4S and spaced vertical side walls 50. The inner vertical wall 46 extends upwardly from the depressed top` portion -36 and terminates above the top portion The outer 'spaced vertical wall 4S extends upwardly from the cap portion 34 and merges with a vertical wall portion 49 extending upwardly from the skirt 28 alongy the body oh-one Yside thereof, as best seen in Fig. 4. The vertical sidewalls 50 extend above the top portion 34 ofthe cap and are full width above the top portion .3'4 but arereducedin width where they merge with 'the annular body 24 down to the skirt 28 of the cap. The outer surface of the circular body is knurled as at 52. The entire cap structure is integrally formed andmolded as an integral unit. The upper surface 45 of the top of duct 44 which is the discharge endV of the cap is downwardly inclined at an angle, as best seen in Figs. 3 Vand 4, away from the body 24. -4
The cap is integrally secured `to 'the neck of the-'tube by rotating the cap clockwise with 'respectto the Vneck to allow the beaded or annular ring 30`of the cap to be positioned in the space 2i) between the bottom of the.
thread 16 and the lower end of fthe'neck. Whilethe inner periphery of the bead 'or lring 3l) is inward o'f the outer edges of the threads 161of the vneck of the tube,'th'e character of the plastic material from which the y"cap :is made will permit the cap to fgivev'suiciently to permit the bead or ring 30 to p'asso'ver the threads 16Tvt'fherninitially securing the cap ltet-the n'e'ckoftlfe tube -How er, nce thisr cap is thus'sec'ur'ed't'o the A'I1 Eik," ring will be positioned inwardly c"of the outer 'edges 'of the threads 16 an'dfwill "engagethe lowerrnost portion or" the thread 16 to hold the cap captive on the neck and prevent removal therefrom. The Vcap may however be rotated counterclockwi'se s'uiciently to permit raising the cap in the space 20 of the neck Ysufficiently to uncover the discharge opening 42 inthe neck of the tube for discharge of the tube contents through the duct 44.
In Fig. 3 the cap 10 vis shown A,in closed position, that is, with the sealing portion 38 of the cap extending partially into the vdischarge opening k22 and closing the discharge opening 2-2 'in the neckof t-hetube toprevent any`discharge of 'the contents of the tube. To permit the contents of the tube to be squeezed out or discharged, the cap 10 is r`otated counterclockwise to elevate it slightly from the top opening 22'of the neck, as best shown in Fig. 3. The sealing portion `38 will then be positioned above vthe neck of the tube andthe boss 38 will serve to guide the paste to the slot 42 and duct 44. In this position the tube when squeezed will iforce the contents through the slotted opening 42 into the duct 44 of the cap and 'outwardly thereof through the top `of the duct. 4The shape of the duct 44 and the inclined ftopils' of the duct 44 will'cause the squeezed material to move outwardly laterally of the top of the duct 'in a ribbon form and lie rspread ii'at on the toothbrush. The cap is held captive and cannot be Unthreaded or yremoved from the neck of the tube.
There is thus provided a cap or closure for. tubes of toothpaste or other paste-like products which are, held captive to the tube but which may be rotated to 'seal or Vunseal the tube opening and "to permit discharge ofthe paste material through 'the duct of the cap when same has been moved' relation to :the dischar.'geopening in the neck to unseal Isaine, yet at all times proyidinga covering foi thef discharge opehing Y22 -infth'eneck of the tube. lThe cap may i in lieu of present day conventional caps.v f i The resilient and ilexible material from which the-cap or closure is made permits the threaded portion' 29 of be formed inexpensively and AVused the body of the cap to engage the substantially rigid threads 16 of the neck of the tube in such a seal tight t so as to prevent the paste material discharged from the tube from ever passing through the engaging threads 29 and 16, therefore the discharged paste can only move upwardly through the `discharge duct 44. Furthermore, the characteristics of the cap material permits the cap tobe used without employing sealing discs or liners.
While the invention here illustrated shows the cap formed of a plastic material which is resilient and ilexible it will be understood that if the threaded neck portion of the container is formed of such a resilient, and exible material that the cap may be formed of a rigid material and the seal tight t between the engaging threads will likewise be effected.
The closure or cap may be made of any size to lit over a container having a threaded neck portion, which neck portion has a much larger diameter than that shown. This is particularly true -in containers which contain liquids. However, a cap or closure formed in accordance with this invention may be there employed and it will operate in the same manner as herein disclosed.
Figs. 6 and 7 show a modified form of spout for the cap or closure. The cap or closure shown in this modification is principally for containers containing liquids and the like. In this modification the cap or closure which lis indicated generally at 56 is formed like that previously -described except that instead of a rectangular shaped duct as previously described there is provided a circular opening 58 in the annular wall portion 40a of the cap which communicates with a circular duct 60 which forms the discharge outlet of the closure. The duct 60 'is tapered to provide a reduced end 62 at the vupper discharge end. The top of the discharge outlet is downwardly inclined at an angle as at 64 to facilitate thedis charge` of the liqid'away'lfrom the closure.
Fig.' 8 shows a modified construction in which the threaded neck V16a of the container is provided with an annular shoulder 66 below the threaded portion of the neck. Said shoulder has a tapered portion 67 and a horizontal portion 68. The closure 10a is formed as previously described. However; the annular bead or ring 30a of the closure will after theclosure is initially applied engage the flat portion 68 of the shoulder on the neck of the container to hold it 1in captive relationship with 4the container.
It will be understood that various changes' and lmodifications rnay be made from the foregoing without depart ing from the rspirit and scope of the appended claims'.
