WASHINGTON KYLE SHEFFIELD AND ALBERT J. HORTON, OF NEW LONDON,'CON- v NECTICUT; SAID HORTON ASSIGNOR TO SAID SHEFFIELD.
Application filed January 23, 1923. Serial No. 614,426.
To all whom it may concern:
Be it known that we, WASHINGTON KYLE SHEFFIEIJ), a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, and ALBERT J. HoR'roN, a citizen of the'United States, residing at New London, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Cover Retainers, of which the following is a specification.
The present invention relates to an improved form of cap retaining means, shown in the accompanying drawings as being attached to a collapsible tube of the well known type and cap therefor, such tubes being used for holding tooth paste, cold cream, and the like, though it is noted that the inventlon is not limited in its application to containers and caps therefor.
One of the important advantages of our device is that owing to its construction it is adapted to be readily removed from a used tube and cap and as readily replaced upon a new tube and cap, without provislon of an means u on the cap or tube other than 1s provide in the present method of manufacture of such tubes and caps.
Another important advantage of our device is its simplicity and economy of manufacture. In ordinary manufacture of these tubes and caps it is now common and standard practice to provide the caps with a knurled portion for use in manually unscrewing the ca and to provide immediately below the urled portion thereof a neck formed by a groove of substantial depth and a lower flan e. Also, in the standard manufacture of t e tubes it is customary to provide upon the threaded opening thereof a neck formed by a clearance between the threaded portion and the tapered shoulder of the tube, whereby to permit of mechanical threading of the said portion during manufacture 1n a clean manner without run-- ninginto the shoulder. This groove is commonly known as the clearance and by tak ing advantage of these standard conditions upon both the tube and cap we have devised a ca clip which comprises two wire grips of slmilar construction joined together by some suitable form .of chain, which chain preferably in the present instance consists of a standard type of ball chain which is now being manufactured in large quantities at a low cost. We have selected this form of chain both for its neatness in' appearance and its extreme adaptability to the requirements in its present use.
v It will be noted .in the drawings herein that the clips are made of stock spring wire, and may be formed in many ways wherein advantage is taken of the resiliency of the wire itself to form a loop which may be resiliently engaged or disengaged with the clearance portion of the threaded nipple of the tube or the groove in the cap.
Another advantage in our device is that, aside from its complete assembly, all of the coacting parts readily lend themselves to machine manufacture with a minimum amount of hand labor, and therefore make for great economy in manufacture, and the construction of the device is so simple that a minimum amount of labor is expended in assembling the device for use on tubes of this class.
Still another important advantage of .our device is that due to its construction as shown, its appearance is highly ornamental and therefore becomes an advertising asset of value on this account alone.
In the accompanying drawing, showing by way of example four of many possible embodiments of the invention, Fig. 1 is a fragmentary, approximately full size, view of a tube showing .our device attached thereto.
Fig. 2 is a substantially full size perspective viewof our device disengaged from the tube and cap.
Fig. 3 is a side elevation of the clip shown in F g. 4; Fig. 4 being one form of our clip construction.
Fig. 5 is a side view of the cap clip shown in Fig. 6; Fig. 6 being another form of construction of our clip. 7
Fig. 7 is a side elevation of another modified form of clip as shown in Fig; 8; Fig. 8' being a plan View thereof.
Fig. 9 is a side elevation of the construction shown in plan in Fig. 10, which is still another form' of clip construction.
Fig. 11 is a plan view of another form of modified clip of similarconstruction to those shown in Figs. 4, 6, 8 and 10.
Fig. 12 is a view showing the plan of readily shaping the cap clip so that it may .not be expanded unduly in placing it over the neck of the cap.
By referring to the drawings it w1ll be seen that our device comprises a collapsible tube or container 10 provided with an outlet neck or nipple externally threaded at its outer end 11 and having a plain or clearance portion 12 between said threaded end 11 and the tube 10. An internally threaded cap, adapted to be screwed on said threaded end 11, has an outer enlarged knurled end 15 and a laterally extending flanged inner end 16 forming a circumferential groove between the flange 16 and knurled. end 15.
Clips 18, each formed of a single piece of spring wire consisting of two oppositely curved grip arms 20, Figs 6,- are adapted to be snapped or sprung into and out of said groove 17 or onsaid clearance 12. The clip attached to the tube may be chased or screwed over the threaded end 11 to clearance 12, as well as snapped thereon. Each clip 18 is provided with an arms-connecting loop "P01431011 22 having its outer end 23, Fig. 5, bent at an angle to said arms 20 to form-an engaging seat loop 25.
A chain 30, made of balls pivotally connected to each other, connects said clips 18 to each other by having its end balls 31 passed between said arms 20 and outwardly therefrom until each said end ball 31 rests in or engages in said seat 25.
To attach a clip to the cap the free ends of the arms 20 are placed in the groove 17 Fig. 12, and the arms forced apart sufiiciently by the flange 16, employing the extending loop portion 22 as a lever, to ahow the arms to pass thereover and seat themselves in the groove 17. To remove the clip it is only necessary to press upwardly on the loop portion 22 which will force the arms 20 apart and allow the flange 16 to pass therebetween.
In the modification shown in Fig. 11, the loop portion 22 is slightly constricted to prevent the clip 18 from'disengaging from the chain when our device is not applied to a tube.
Another form of clip, 18", for accomplishing the same result, is shown in Fig. 10, in which the loop portion 22 is given a half turn relative to the arms 20", thereby forming seat eye 25 in which rests the end ball 31 of chain 30, the arms 20 being slightly sprung apart to permit passage therebetween of'the ball-connecting portion of the chain.
Figs. 4 and 8 show the arms 20 and 20 extended to meet each other; this form of clip being adapted for screwing on threaded nipples, such as nipple 11, Fig. 1.
