Definitions

the invention relates to a closing ring for clampingly fixing a lid on the bead of a metal can.
a closing ring is known.
the invention has for its object to embody a closing ring such that the reliability of the closure is improved. This reliability is expressed in the maximum height through which a filled can can fall without the lid springing off the can.
the closing ring has the feature that the closing ring comprises a band which engages round the top rim of the lid and the lower edge of the bead and extends over more than the periphery of the bead and the lid such that the ends of the band have in common an overlapping zone where the ends are mutually connected, and that the outer end of the band has a pull tab.
the closing ring is prefabricated and placed with force over a temporarily closed can. Due to the gripping under the bead of the can with simultaneous pressing of the lid thereon, generally via a sealing mass or compound, a very robust clamping seal is realized.
the can can be opened by breaking the closing ring. This breakage takes place by gripping the pull tab with force and pulling it sideways. The connection between both ends of the band is hereby broken.
the closing ring can have the particular feature that the ends of the band have a bead in common in the overlapping zone on both axial ends.
the beading operation can take place such that the amount of beaded material corresponds to once the material thickness. This construction allows working of comparatively thick material.
the closing ring can have the particular characteristic that the pull tab can be separated from the associated end by breaking a weakening line bounding the pull tab.
the advantage is achieved that it is relatively easy to remove the pull tab because the breaking takes place in stepwise manner.
the tensile strength of the band is nevertheless great.
This latter embodiment can for instance have the feature that a pattern is a notched edge, more particularly such that the notched edge of the one end comprises lips which engage into recesses in the other end.
the closing ring can have the feature that the pull tab has a hole on its free end.
a still greater facility in gripping the pull tab is obtained with an embodiment in which a larger, second hole is situated in the band below the hole of the pull tab.
This latter variant can also be very practical for use in combination with a can the bead of which has a peripherally running recess.
a practical embodiment is that in which the pull tab is narrower than the band and is bounded at the sides by two weakening lines which extend parallel in lengthwise direction and which each connect on their end remote from the free end of the pull tab to an additional weakening line running to the sides of the band.
This embodiment has the particular feature that the additional weakening lines are situated in the region of the overlap. This embodiment combines easy tearing off with a great tensile strength.
Figure 1 shows a metal can 1 according to the prior art comprising a bottom 2 and, connected thereto, a standing wall 3 in which the zone remote from the bottom 2 comprises an outward extending bead 4 (also see figure 3) having in section a first part 5 extending through about 360°, a second part 6 lying against the first part 5 and extending through about 90°-120° and a third part 7 connecting thereto with a considerably smaller radius of curvature.
Figure 3 shows the can 1 before it is closed by a lid 8.
Figure 2 shows the can 1 after it has been closed by the lid 8.
Figure 3 shows the manner in which the lid 8 co-acts with the can 1.
a filler mass or compound 10 is situated between the rim 9 of the lid 8 and the top surface of the bead 4. This mass serves to seal the lid 8 relative to the can 1.
FIG. 4 shows a closing ring 12 according to the invention.
This closing ring comprises a band 13 of metal which extends over more than the periphery of the bead 4 and the lid 8 such that the ends of the band 13 have in common an overlapping zone 14 where these ends are mutually connected.
the outer end of band 14 has a pull tab 15 with a hole 16 therein such that the pull tab can be gripped with a pin, screwdriver or other suitable object.
the connection between the ends of the band 13 in the overlapping zone 14 in this embodiment is such that the ends of the band have in common a bead 15, 16 in the zone 14 on both axial ends.
Figure 5 shows a variant in which a closing ring 17 has an overlapping zone 18 in which the ends of the band 19 forming the closing ring 17 are mutually joined by the beads 15, 16 and wherein the outer portion thereof moreover has a pattern of lips 20 having free zones 21 situated therebetween.
Figure 5b shows similar recesses 23 into which the lips 20 can engage.
the closing ring 17 hereby possesses a great peripheral tensile strength. It can nevertheless be broken by tearing loose a pull tab 22 in more or less radial direction along weakening lines 23.
Figures 5c, 5d and 5e show the manner in which the weakening lines 23 are embodied.
Figure 6a shows a closing ring 24 comprising a band 25, the ends of which mutually overlap in a zone 26. Situated at the location of the overlapping zone is a pull tab 27. Below the hole 16 in pull tab 27 the underlying portion of the band 25 has a hole 28.
This embodiment is particularly practical in the use of a metal can with a bead on the upper part having a recess on its peripheral zone located furthest to the outside. A pointed object, for instance a pin, a screwdriver or the like can thus be inserted through the hole 16, through the hole 28 into the said recess in the underlying bead.
the pull tab 27 can hereby be removed easily in more or less radial direction along the weakening lines.
Figure 7a shows a variant wherein a pull tab 29 extends with its hole 16 beyond the overlapping zone 30.
FIG 8a shows an alternative.
the closing ring 30 is mutually adhered with its overlapping ends in the zone 31 by means of a spot weld 31.
