1l (Cl. 221-60) This invention relates to closures generally but in particular, to closures for paste tubes and the like.
The objects of the invention are to provide a ii simple, inexpensive, easily assembled construetion, which will be tight sealing and maintained so, Without the use of springs or lother adjuncts.
These and other desirable objects are attained by the novel features of construction, combina- 'iil tions and relations of parts hereinafter de,- scribed, illustrated in the accompanying drawing and 'broadly covered in the claims.
The drawing accompanying and forming part of the speciiication illustrates one simple pracl tical embodiment of-the invention, but it will be understood that the structure may be modiiied as regards this disclosure within the true intent and scope of the invention as hereinafter deiined and claimed.
Fig. l is a broken side elevation of a form of the invention as applied to a paste tube type of container, showing the cap in openv position.
Fig. 2 is a broken sectional view with the cap shown in the closed position.
Fig. 3 is a top plan view of the parts as shown in Fig. l.
Fig. 4 is a broken elevation as viewed in the direction of arrow 4, Fig. 2.
` Fig. 5 is a view similar to Fig. 2, illustrating a slight modication.
The container to which the invention is applied is here shown as a paste tube 5, of typical design, as regards the contracted end or head portion 6, and the spout or neck portion 7.
The neck structure is distinctive however, in that it has a spherical portion 8, at one side having aradiusR drawn for instance from the center of the neck and a spherical -portion 9, at the opposite side drawn with the greater radius R. from the same center. This combination oflesser and greater spherical segments, merging one into the other, produce an inclined relatively sharp edge or chime 10, about the discharge throat 11. Y Y
The cap or closure proper, comprises a cap member 12, pivotally mounted in this instance, by having sidelugs or extensions 13, embracing the neck and provided with inwardly extended pintles 14, entered in pivot sockets 15, in the sides ofthe neck. In this particular instance, the pivotal axis of the cap is in line with the center of the different cru'vaturesl of' the neck, but these need not coincide. In some instances, the pivotal center is offset forwardly or toward the lower side of the neck, that is, to the right in Fig. l.
The interior or underside of the cap is shown in Fig. 2 as formed on a slant generally oorresponding to the inclination at the end of the neck and as havinga major curvature 16, at one edge generally corresponding to the higher spherical portion of the neck and a minor curvature 17, at the opposite edge,fcorresponding in a general way to the lesser spherical portion at the lower vside of the neck. Between such curved portions, the cap has a central somewhat spherical protuberance 18, corresponding to the general outline of the inclined end of the throat, in the nature of a rounded pad to extend down into such opening. This rounded protuberance also is of suicient extent to stress the cap as it is forced lover the lower edge of the opening and hence cause the cap to snap into its iinal position, sealing the opening.
For some liquid and pasty materials, a cork or equivalent seal is required. For containers of such materials, the cap may have a disc 19, of
cork or other suitable resilient sealing material seated therein. This cork gasket aids the snap action described and, expanding as it does inwardly from the compressed portions held by .the sharpened edge of the neck, it aids in holding the cap in the sealed position. To prevent dislodgement, the sealing disc may` be seated in a caviti7 20, shaped to receive the same in the hollow of the cap. Other means :for securing this disc may be employed, or the disc simply be held in place by its engagement and deformation over the center projection of the cap.
'I'he projection of the cap, passing over the low side of the neck and against the'high side,
-serves as a stop limiting further movement. No
stops therefore are required to prevent movelment of the capV past the fully sealing position.
As a matterl of indicating the direction in which the cap opens, a nger recess, such as shown at 21, may be provided, faced to take the pressure of the nger when applied in the proper opening direction.
The cap may loe-made of the same material as theftube "or container, such as lead and tin compositions, Vor be made for example of the various molded materialscommonly employed for tube caps and 'the like. The manner of hinging the cap may. be varied. In the construction illustrated, the pintles are indicated as formed by material from the-cap sides into the pivot cavities, leaving the indentations 22,
ance with the end shape ofc the passage 11.
Thus if thispassage 'be square or of attened' lrectangularl cross-section to cause paste for example, to issue as a thin ribbon or tape, the
I cap protuberance will be correspondingly shaped, so as to seat and seal in the end of the passage.
The radii for the'end curvatures need nothave the samecenter and in fact, in some instances as in Fig. 5, the curvature at one side of the neck will be drawn from a diiferent center from the curvature at the opposite side of the neck and be of diiferent radii or as in this special instance' Fig. 5 of the same radii R R.. Also, in
s ome constructions, thel curvature at the high side instead of being on a longer radius as is the.
case in Fig. 1, may be on a shorter radius than the curvature at the lower side of the neck. In such construction, the arc would be flatter at the lower side 8 of the neck, facilitating to some extent the sliding movement of the cap thereover. In all such combinations however, it is desirable to have the pivotal center of the cap approximately coincide with the center of curvature at the higher side of the neck so that the cap will firmly seat in its fully closed position. While the pivotal mounting disclosed is practical,
-in some .instances it is feasible to connect the parts by providing rigid hinge pintles on the cap and to enter these along grooves formed in the sides of the neck, iinally closing in these grooves in back of the pintles to thus x the pintles in the final pivoting position for the cap. According to other methods, pivot pins -may be driven through the hinge lugs into anchored position in the neck or a single pivot pin be driven straight through the lugs and neck,.scored or roughened at proper points to lock in the material of the neck and with smooth -ends for the cap to rock upon. As a variation of the latter, the single pivot pin may have its ends riveted or otherwise secured in the cap lugs and rock in the openings in the neck.
The neck need not be cylindrical and may be elliptical or vario angular shapes in crosssection, for example, to match the cross-sectional shape of the paage. Thus with a narrow slot form of passage for discharging the paste as a ribbon, the neck might be elliptical in crosssection, with the axis of elongation on the major dimension of the slot. In such construction, the spherical surfaces at the end ofthe neck might be elongated in the direction of elongation of the ellipse, with strictly spherical surfaces only at the ends of the ellipse. 'This elliptical form of neck for ribbon discharge saves material at the'sides of the neck and also in enabling a narrower form of cap to be employed.
Various other modifications may, be made within the scope o f the following claims.
What is claimed is'.
1. A closure structure, comprising in combination with a neck having spherical merging end surfaces of diierent'radii at oppositesides of the same, a hinged cap Amounted to travel over the surface of lesser radius toward, over and into close tting engagement with said spherical surface of greater radius.
