CRIMPED CAP REMovER Filed sept. 2o, 195o Patented Oct. 16, 1951 UNITED sIAtr-E..s PATENT .oiFFlciE CRIMPED CAP REMOVER Mikolali .Kondakow and .James Wong, :Port.Arthur, ntari'o, :Canada vApplicationSeptember 20, 1950, Serial No. 185,838 In Canada August 29, 1950 This ,invention "relates `to means for removing crimped caps from bottles, and :the objects of fthe'invention are:
'1. To 'enable lthis type of capito be readily vand easily removed laterally of the bottle top.
2. To prevent the fractioning means for the cap from being longitudinally displaced while the bottle is handled.
In its broadest conception the invention comprises a crimped cap generally of common construction but suiciently slit to form it almost into two halves which are retained in relationship by unslit portions of the cap, and a rupturing member piercing said cap and over portions of which parts of said cap are clamped, as hereinafter more particularly explained.
Fig. 1 is a plan view of the top of the cap.
Fig. 2 is a plan view of the cap without the ring.
Fig. 3 is a plan view showing the cap ruptured.
Fig. 4 is a section on the line 4 4, Fig. 1.
Fig. 5 is a section on the line 5-5, Fig. 1.
Fig. 6 is a plan view of the underside of the cap.
Fig. 7 is a view of the rupturing member or ring.
In the drawings like characters of reference refer to the same parts.
As shown in Figures 4 and 5, the rupturing element is shown in the preferred form of a ring, and this ring lies chiefly snugly against the top side of the cap.
The cap 2 is crimped and clamped to the top 3, of the bottle by the usual clamping means (not shown).
The cap 2, is slit, as shown at 4, for most of its diameter but so as to leave an unslit portion 5, in the crimped rim, which acts somewhat as a hinge (Fig. 3) when the two halves of the cap are separated. Near the opposite end of said slit 4, and nearer the centre of the cap than the extremity 6, of said slit, the cap is equally slit at each side of the slit 4, as shown at 1. The cap is further slit at the extremity 6, equally at each side of the slit 4, as shown at 8, and a slit 9, is formed in an angular position in said cap at each end of the slit 6, and directly in communication therewith. Spaced apart from the slit 6, is a slit I0, which extends equal dis` tances beyond the diameter of the cap measured along the slit 4. The slits 1, 8, and I0, lie parallel to each other. At each end of the slit I0, is a slit I I. These slits I I are substantially parallel to the slit 4. In alignment with the outer ends of the angular slits 9, and spaced apart therefrom, are slits I2, so positioned as to sumciently weaken the top and crimped flange of ithe reap .eas Lto permit y'the cap to be ruptured "in .alignment with said `slits I2.
4As 'the `various fslits 'are cut 4in the top of thev cap, Iwo Yseparated v'ears 13., are fromed 'up :along the dotted lines I4. (Fig. 2.) Simultaneously with the formation of the ears I3, the metal bounded by the slits 8, 9, Il) and II, is displaced, thus forming a bridge I5, and a tongue I9. Forming said bridge and tongue provides a passageway I6, through which the ends I1, of the ring I8, are passed to be positioned under the ears I3, and over the tongue I9. As the ears I3, and bridge I5, are clamped over the ends I'I, these ends are rmly gripped between ythese ears and to bridge I5, and tongue I9.
To prevent the longitudinal displacement of the ring I 8, the upper side of each end I'I, is provided with a shoulder 20, against which one side of the bridge I5, abuts. In forming the shoulders 20, a sloped surface 20', is formed against which the bridge I5, is held. This construction prevents longitudinal displacement of the said ring in either direction.
The ring I8, is provided with a lug 2l, which promotes ease of lifting the ring.
A cork disc 22, is positioned within the cap, and, if desired, afmetal disc 23, may be interposed between the cap and said cork disc. However discs made of any suitable material may be used in the cap as lthe contents of the bottle the cap is used on may require to be kept in a good condition.
As shown in Fig. 7, each arcuate side of the ring I8, terminates in an inturned end I'I. These ends extend parallel with the slit 4, and their line of contact is in alignment with said slit.
To remove the cap the ring I 8, is moved in the direction of arrow (Fig. 5). This movement displaces the ears I3, into the position shown in Fig. 3, and by the dotted lines in Fig. 4, and simultaneously the bridge I5, is lifted thus rupturing the material of the cap between the outer ends of the slits 9, and the slits I2. This movement tears la fragment a (Fig. 3) away from the cap except at the location b (Figs. 3 and 6). By pulling the raised ring I8, to the right, the halves of the cap are moved apart on the hinge 5, and may be lifted olf the bottle.
The shoulders c of the ring I8, when this ring is lifted, are forced into contact with the cap 2, and thus act as the fulcrum for the inturned ends I1.
As shown in Fig. 5, the ears I3 lie upon the end I1, above the shoulder 20, and the bridge I5 abuts against the said shoulder for its full height.
Changes in construction may be made in that herein disclosed without going outside this disclosure and the terms of the claims.
We claim:
1. A container closure comprising a crimped metal cap having a slit in its median line, and having other slits at spaced intervals transversely through said slit, and, at the ends of two of said transverse slits having slits at an angle to said diameter slit, thus forming a pair of ears; a tongue; and a bridge intermediate said ears and said tongue; a disrupting member having an inturned portion extending below said bridge and above said tongue, said ears and said bridge clamping said extension to hold said member snugly against said cap.
2. A container closure comprising a crimped metal cap having a slit on its median line, and having other slits at spaced intervals transversely through said slit and, at the ends of two Yof said transverse slits having slits at an angle to said diameter slit, thus forming a pair of ears; a tongue, and a bridge intermediate said ears and said tongue; a disrupting member in the form of a ring having an inturned portion extending below said bridge and above said tongue, and provided on the upper side of said inturned portion with a shoulder and a sloped surface, the said ears being clamped over said inturned portion above said shoulder, and said bridge being clamped on said sloped surface and abutting said shoulder thereby holding said disrupting member securely in position.
