Patented Apr. 1, 1952 SEABINGAND DISPENSING CLOSURE FOR CONTAINER NECKS -,QdberE.-Boadway, Pasadena, Calif., assignor to Innovations/Ina, Los Angeles, cant, a-corporation o'f' Delaware Application-April 24, 1947,.Scrial No. E3503 Thisinvention is a closure for containersysuch .for example, as collapsible tubes, bottles, jars,
canaan'd thelike.
Thefinvention is a modificationof and an 1m- ,Drovement on the closureior, containers shownm .n yapplication Ser. No. 643,869, filed January 28,'$I94 6, nowPatent No. 2,582,224,.issued January 15,1952.
The closure of the present invention is of the captive cap type, that is.to say, of the type where the cap is rotated a turner two "to theopen or closedposition, but is not completely removable, .therebyqpreventing the loss of "the cap.
The, neck portion-of the present closure may be formed as partof the container itself; however, the neck portion. of the closure may be formed separately and provided with interior threads for engaging with exterior threads'on the container, whereby'the closure ,0! theinvention isapplicable ',to,;alrea'dy.existing typesof tubes, bottles, and
cans.
The'principal object of the present invention is to provide .a closure whereintheneck portion lis provided with exterior threadsthe upper end Lof which terminates in alimitingabutmentand [into en agement with the thread; when so enaged, the cap may be rotated tomove it-toopen enclosed position, but when the cap is moved to the .open position, the interrupted thread 'or inclined lug will engage'against this limiting abutment ,for,preventing.,any. further rotation, thereby preventing'the removal of the cap, so that it cannot be lost.
Another object of the invention is to provide an improved seal between the upperpart of-the neck and the closure cap. This improved seal comprises an annular gasket carried by the upper part of theneck. LThe shoulder on which the gasket'is seated and the ,inside upper part of a cap areeach provided with an annular knife ledge whicheknife edges, when .the cap is screwed to closed position, bite into. the lower and upper edges o f.said gasket for makinga very tight seal,
Theclosure of this invention is adapted .to be usedon containers for toothpaste, shaving cream,
:cosmetic-creams, medicines, liquids generally,
-,oily and fatty materials, liquid shoe polish, paints and pigments, glue, adhesives, and the like.
Further advantages of structure and operationare snow to be described .in'connection with "the accompanying drawings wherein:
2 Fig 2-is a-sectiona1 view ofthe closure :cap. Fig.3 is a side view of the parts showninlFig. 1. Fig. 4is a vertical section of amodification whereinthe cap is threaded directly onto the neck of the container.
Fig.5 is-a side elevation of the top part of the container of Fig.4.
Fig. 6 is avertical section of the closure cap of Fig.4.
Referring now to these drawings, '2 indicates the-neck portion of a collapsible tube,-bottle, can, or the like, provided with exterior screwthreads 4. The neckportion or memberofthe closure, indicated, generally at 6, which alsofunctions as an adapter, threads-8 engageable'with the exterior threads 4 on' the container. Neck 6 could be formedas an integral part of "container 2, as in Fig. 4, in-which case interior threads '8 would not be used The neck, portion fi, if not integral with thecontainer, is preferably permanently secured tothe neck-2 thereof by cementing it directly-thereto. However, it is preferred that an annular gasket Ill, seated on the upper edge of the neck 2 of the container, be bonded or cemented to the upper edge 2 and to the annular portion l2 of the neck'fi.
The neck portion 6 isprovided with single or double "exterior screw threads M, such threads not running all the way to the top as usual, but terminating in a limiting abutment I6.
Cooperating with the parts just describedis a cap H3 provided with finger corrugations l9 and with a centraldispensing aperture 20, having an inclined surface 2!, The lower or skirt portion 22 of the cap is provlded withwan inwardly-projecting interrupted-thread or inclined lug 24. The cap I3 is preferably made of plastic or of -a mate rial having some resiliency, and the cap is engaged with the n ck by forcing theinterrupted thread 24 over the upper edge of the topmost thread 14, shown at if, whereby the lug will snap into the thread M. Once in the thread [4,
.it will ride therein as the cap-is rotated to move .it to open :or closed .positionsbut further rotaedge .28. .Seated onshoulder .26 is a vertically disposed annular gasket .30, ,of a thickness adapted to engage snugly against the interior upper surface 32 of the cap. The under, outer is provided with interior screw portion of the cap is provided with an annular knife edge 34. The snug engagement between the gasket 30 and the surface 32 of the cap, together with the sealing effect, achieved by knife edges 34 and 28 biting into the upper and lower edges of the gasket, form an effective seal against leakage of the contents, serving especially to prevent the escape of the contents onto the exterior screw threads I4.
The neck member 6 is provided with corrugations 36, useful in rotating it, in case its removal is desired. The neck member 6 is also provided with dispensing apertures 38 and with a beveled plug 40, for closing aperture 29 in the cap. Beveled surface 42 of the neck and beveled surface 2| of the cap are at somewhat different angles, forming a wedgelike space 44, the result of such construction being a sharper line of 'contact between the upper portion of the beveled surfaces.
In that form of the invention shown in Figs. 4, and 6, the neck portion of the container is formed with special threads, with which a somewhat modified type of cap cooperates. It should be understood, as already noted, that with the form of-invention shown in Fig. 1, the threads M'could be formed directly on the neck of the container; and also that the modified form of neck, dispensing openings and cap, now to be described in connection with Figs. 4, 5 and 6, could also be used with the type of closure shown in Figs. 1, 2 and 3.
Referring now to Figs. 4, 5 and 6, the neck 50 of container 52, shown as a collapsible tube, is provided with external threads 54, generally similar to threads H; of Fig. 1. The upper part of the thread is cut away, to leave an inclined edge 54'; positioned at the upper or right hand end of edge 54"15 a limiting abutment i9, analogous to limiting abutment 15.
The neck 50, above the threads, is cylindrical, as at 53. The frustro-conical top 58 is provided with escape apertures 60, and has a solid top 6!.
The cap 62 is provided on its interior, lower portionwith an inclined interrupted thread 24,
analogous to interrupted thread 24 of Fig. 2.
. The cap is engaged with the neck by forcing the interrupted thread 24' over edge 54, the cap being somewhat resilient and so permitting this. The cap is thus threadably engaged with the neck 24 moving in thread 54. The opening movement, however, is limited, by the upper end of 24' engaging abutment It. This movement is of course sufficient to clear apertures 69 so that the paste or the like is dispensed through the central aperture 64 in the cap.
The interior of the cap is provided with a cylindrical wall 66 which slidably and snugly engages surface 56 of the neck. The inner, upper surface 68 is of frustro-conical shape and such surface is provided with upper and lower annular knife edges 79 and I2, which bite against the conical surface 58, above and below apertures 69, respectively, thus providing an efiective seal. The snug fit of surfaces 69 and 56 and the lower knife edge 72 keep dispensed material from the threads. The cap may be provided with serrations 74 for use in opening and closing the cap.
In operation, the cap is opened or closed by turning in the usual way. However, the turning movement is limited by 24 engaging abutment I5, in which position the apertures 60 and 64 are clear. The cap cannot be removed, however, because24 hasbeen snapped over edge 54'.
The parts described may be made of any desired materials, such, for example, as metal or plastic.
The closure of the invention is of simple and sturdy construction, susceptible of quantity production and provides an effective closure for use with containers for liquids, pastes, oils, and the like. with the exterior screw threads on the neck, it cannot be removed and so loss of the cap is effectively prevented. The closure may be applied to standard containers, as in Fig. 1, or the container may be modified, as in Figs. 4 and 5. In both forms, leakage of the contents is effectively prevented. A
While the invention has been described in some detail, it should be understood that the invention is not to be limited to the precise details illustrated, but may be carried out in other ways.
I claim as my invention:
1. A closure for a container, comprising a neck portion having an exterior screw thread thereon, said screw thread being cut out near the top thereof for a substantial distance, such cut out providing an arcuate notch, extending for a substantial distance around the exterior of the neck, one end of said notch being formed into an abutment, a cap having no threads on the interior thereof, and provided on the interior thereof only with an inclined arcuate lug, extending for a susbtantial distance around the interior of the cap, said lug being adapted to pass through said out out in the thread and into operative engagement with the root of the thread just below the cut out, whereby the rotational movement of the cap toward the open position is limited by the upper end of said inclined lug coming into engagement with said abutment, the cap being provided with a central outlet, and a centrally positioned plug carried by the neck, cooperating with said central outlet in the cap.
2. The combination as set forth in claim 1, said neck portion being provided with an interior screw thread for engagement with an exterior screw thread on a container, to serve as an adapter neck.
