Definitions

  • the invention relates to an easy-to-open cover made of sheet metal, in particular sheet steel, for containers, in particular cans, with the features of the preamble of claim 1.
  • Such lids are usually made of aluminum sheet and are relatively easy to open and are environmentally friendly, since they ensure that after opening there are no individual parts that are lying around and can lead to injuries or environmental pollution.
  • US-PS 39 67 752 shows an embodiment with a one-piece opening part, the longitudinal axis of which extends in alignment with the longitudinal axis of the symmetrically designed grip tab.
  • US Pat. No. 3,967,753 shows a one-piece asymmetrical opening part, the longitudinal axis of which extends transversely to the longitudinal axis of the grip tab, which in turn comes to lie with its front breaking end over a section of the score line in order to initially break in and close it ensure that the entire opening part tilts into the interior of the container when the scribing point moves on.
  • the US-PS 33 26 406 shows an embodiment in which the opening part is divided into two opening part halves by an additional score line to expose a sufficiently large pouring opening.
  • Each opening part half is assigned a separate grip tab, which is attached to the opening part itself.
  • Another embodiment for an opening part divided into two opening part halves by an additional score line is shown in US Pat. No. 3,446,389. In this case, the ratchet nose of the grip tab lies above the additional score line which also forms an axis of symmetry of the opening part.
  • the grip tab has two functions, namely to break a predetermined section of the score line at the beginning of the opening process. Thereafter, in order to expose the pouring opening, the scribing point must be made to move further along the score line, with the grip tab at the same time securely kinking the opening part and pressing it into the container.
  • the pouring opening must be of a sufficient size to enable uniform, trouble-free pouring.
  • Embodiments are therefore preferred in which the free edge of the handle tab at its breaking end protrudes only a small amount above the opening part and is at a greater distance from the opposite score line.
  • the present invention also relates to this embodiment.
  • the distance between the free edge of the tear-open end of the grip tab and its attachment point, i.e. the lever arm effective when the score line is initially broken should be as small as possible.
  • the distance of the free edge of the burglary end from the attachment point of the grip tab i. the effective lever arm should be as large as possible.
  • the pressing of the opening part into the interior of the container is particularly advantageous if the opening part is designed and oriented according to the teaching of claim 3.
  • the second function of the grip tab can be performed well even with a relatively short distance between the free edge of the opening end and the attachment point of the grip tab, since the longitudinal axis of the grip tab is aligned with the shorter axis of symmetry of the opening part.
  • a sufficient opening cross section is nevertheless obtained, since the shortening of the opening width in the direction of the longitudinal axis of the handle tab can be adequately compensated for by widening the opening in the direction transverse to it.
  • This particularly advantageous cross-sectional shape and orientation of the opening part can also be used both in the case of a one-piece design and when the opening part is divided into two halves.
  • the special contact areas between the opening part and the grip tab which are effective during the initial breaking in of the score line section near the attachment point of the grip tab, can be formed by cup-shaped, knob-shaped or wart-shaped formations on the grip tab and / or on the opening part.
  • the new cover is preferably made of sheet steel, which has only been used to a limited extent for tear-open covers because of the comparatively high break-in and tear resistance.
  • Figure 1 shows the lid 1 in plan view before attaching the associated grip tab.
  • Figure 2 shows a detail of the lid mirror of the lid 1 of Figure 1 with the handle tab attached.
  • Figures 1 and 2 show a preferred embodiment for a one-piece opening part.
  • a continuously curved notch line is provided in the cover mirror 3 surrounded by the cover edge 2 and delimits an opening part 6.
  • the score line 4 has a narrowly defined bending zone 5, via which the opening part 6 is connected to the cover mirror 3 in one piece but can be bent off.
  • the score line 4 delimits a generally symmetrical oval outline of the opening part, which is determined by a short axis of symmetry 7 and a longer axis of symmetry 8.
  • the bending zone 5 of the score line 4 is offset to one side by a small amount with respect to the shorter axis of symmetry 7.
  • a rivet 9 is formed from the sheet metal of the cover mirror, which rivet is arranged in the immediate vicinity of a notch line section that runs in the opposite direction to the other notch line.
  • the opening part 6 is arranged opposite the edge 2 of the cover in such a way that the shorter axis of symmetry 7 is aligned with a radius of the cover.
  • the arrangement could also be such that the longer axis of symmetry 8 substantially coincides with a cover radius.
  • a lever-shaped grip tab 10 is fastened flat on the cover mirror 3 and is made of sheet metal in a known manner and is stiffened accordingly.
  • the grip tab 10 has a grip section 11 which lies outside the opening part above the cover mirror and a rupture end 12 which projects beyond the opening part 6 only to a limited extent.
  • the opening has a free edge 15.
  • the grip tab is fastened by means of the rivet 9 via a fastening tab 13 that can be bent over a line 14.
  • the grip tab is fastened in such a way that its longitudinal axis 16 is aligned with the shorter axis of symmetry 7 of the opening part 6.
  • the free edge 15 of the breaking end 12 is asymmetrical with respect to the longitudinal axis 16 of the handle tab 10, the breaking end forming a nose 17 directed towards the side of the fastening rivet 9 facing away from the bending zone 5a of the score line 4.
  • a special contact area 18 is formed between the opening part 6 and the grip tab 10.
  • this contact area can be a hemispherical knob 47 pressed into the grip tab in the direction of the opening part. But it could also be such a knob in the opening part itself, which faces the grip tab 10.
  • two frustoconical warts 48 and 49 are provided in the grip tab 10 and opening part 6, which lie on top of one another before the opening operation or are only slightly spaced apart.
  • the shape can also be triangular, as shown at 51 in FIG. 6, or it can be designed as an angular rib.
  • the distance 22 of the contact areas 18 from the attachment point 9 is different from the distance 21 of the nose edge 17 from the attachment point 9, namely smaller.
  • a critical point when the marking point continues to move along the score line is the point 27 of the score line, which is at the greatest distance from the bending zone 5a. It can be seen from FIG. 2 that the nose 17 projects in relation to the shorter axis of symmetry 7 in the direction of this critical point 27.
  • the effective lever length 25 when cracking is additionally significantly shortened, so that there are much more favorable force ratios during the break-in in the break-open zone 20.
  • a much longer lever arm 21 is achieved by the nose 17 despite the shortening of the length of the breaking end 12 to the distance 24. So you get much more favorable conditions than before for both functions of the grip tab.
  • FIG. 3 shows a possible embodiment with the opening part 6 divided into two halves.
  • the continuously curved notch line 31 has an almost oval course, the longitudinal axis of the opening part 6 coinciding with the longitudinal axis 36a of the grip tab 36.
  • the opening part is divided into two equal halves 33 and 34 by an additional straight notch line 32 coinciding with these axes, which can be stiffened by deformations in the manner shown.
  • the grip tab is symmetrical about its longitudinal axis 36a and is arranged centrally over the rivet 38 between the bending zones 40a, 40b assigned to the two opening part halves 33, 34.
  • a special contact area 39 similar to the previously described contact area 18 is provided between the opening part 6 and the grip tab.
  • this contact area is arranged close to the initial break-open zone 41 arranged between the two bending zones of the score line and thus very close to the rivet 38.
  • the contact area is laterally offset to one side of the longitudinal axis 36a of the grip tab 36.
  • the grip tab is again attached via a snap-off fastening tab.
  • a second contact area 39b can also be provided on the other side of the additional ker line 32.
  • it can have a predetermined free travel distance with respect to the contact area 39a, for example a contact projection of a lower height, based on the pivoting movement of the grip tab when opening.
  • the break-open area 41 of the score line is first brought to break in by lifting the grip tab.
  • the scribing point then runs according to the arrows first over the straight additional score line section 32 to the point of the score line which is furthest away from the grip tab, whereupon two tear points are formed which continue essentially symmetrically on both sides along the score line to the bending zones.
  • opening part can also be significantly improved if the opening part of oval cross-section with its longer axis of symmetry is arranged transversely to the longitudinal axis of the grip tab, as the embodiments according to FIGS. 7 and 8 show.
  • the embodiment according to FIG. 7 differs from the one according to FIG. 3 by this outline shape and the orientation of the opening part 6 which have just been mentioned.
  • the two bending zones 59a, 59b of the continuously curved score line 56 are symmetrical to the straight score line section 60 on both sides at a short distance from the attachment point 65
  • the contact area 64 which is shown here as a wart-shaped elevation in the opening part 6, is laterally offset from the straight notch line section 60 at a distance from the notch line section defining the rupture zone, which corresponds approximately to the distance of the fastening point 65 from this notch line section.
  • the longer axis of symmetry 63 of the oval opening part lies approximately perpendicular to the straight notch line section 60 and thus also to the longitudinal axis of the grip tab.
  • the opening part 6 is divided into the two opening part halves 61, 62.
  • the embodiment according to FIG. 8 differs from that according to FIG. 7 in that the bending zones 72a, 72b are laid at the ends of the longer axis of symmetry 8 of the opening part 6.
  • the essential part for the breaking process the handle tab is shown in dash-dot lines in this representation. It can be seen that the opening end of the grip tab 76 is formed symmetrically to the straight notch line section 73 and to the opening zone 79 and to the fastening point 77, and its free edge is continuously curved.
  • the handle end of the handle tab lies above the cover mirror 70 outside the two halves 74, 75 of the opening part 6.
  • the score line is sufficient when the tearing process after passing the straight score line section 73 reaches the critical point 71a of the score line 71 has, reliably on both sides, the rupture end presses both opening part halves 74 and 75 securely into the interior of the container.
  • the contact point also supports the tearing of the opening zone into the entry end of the straight additional score line section 73 in addition to facilitating the opening process.
