DESCRIPTION OF THE INVENTION

(9) FIG. 1 discloses a panel 1 according to the invention. The panel 1 comprises a peripheral edge to be connected to a container body (see FIG. 13) of a container. A tab 4 is connected to the panel 1 via a rivet 5 which is located in the central part 6 of the tab 4. The tab 4 further comprises a front tab part 7 located near a score line 8. The score line 8 has a circular form extending between the peripheral edge 2 and a central panel part 9 to be removed by actuating and pulling the tab 4.

(10) The tab 4 further comprises a rear tab part provided with a tab opening 11. The rear tab part 10 is intended to be gripped by the user of the can. The tab 4 is generally gripped with two fingers via the tab opening 11 and the free end of the rear tab part with two fingers, or by extending with one finger via the tab opening, or by penetrating beneath the free end 12 of the tab 4 with one finger.

(11) Lifting of the rear tab part 10 will result in a contact of the front tab part near or at the score line 8 thereby popping the score open and forcing an opening. Ultimately by lifting and pulling the tab 4 and moving it upwardly the central panel part 9 will be removed and an opening formed defined by the score line 8.

(12) As shown in FIG. 1, the central panel part 9 has a terrace structure having an outer terrace 13, an intermediate terrace 14, and a central terrace 15.

(13) The panel 1 according to the invention is provided with prevention means 16 for preventing engagement of hooking of an external can structure with the rear tab part. Thereto, the prevention means 16 have the form of 2 elongated embosses 17 and 18 extending spaced apart sidewise of the rear tab part 10. The spacing 19 between the two embosses 17 and 18 is such, that an external can structure is not having such sharp or pointed structures that it could penetrate between the two embosses 17 and 18 into the spacing 19.

(14) The panel 1 is further provided in the central terrace 15 with an indent 20 forming a finger access to be used by the consumer when gripping the free end of the rear tab free end 12 of the rear tab part 10 of the tab 4.

(15) As shown in FIG. 2, the embosses 17 and 18 have an elongated and curved structure which aligns with the outer form of the rear tab part 10.

(16) FIG. 3A shows that the two embosses 17 and 18 extend adjacent (not beneath) the rear tab part 10. The height h of the embosses 17 and 18 is such that they are extending over height which is larger than the height of the underside of the rear tab part during production filling cooking and storage. In this respect it is noted that FIG. 3A shows the panel in its original shape during manufacture during which the rear tab part 10 lies on the surface 21 of the central terrace 15. However, after filling and closure of the panel 1 onto the container, as shown in FIG. 3B, then the free end part 10 is extending above the surface 21 leaving a clearance between the free end part 10 and the surface 21. Still, penetration of any external can structure is avoided because the embosses 17 and 18 still extend above the underside of the rear tab part 10 and prevent such penetration.

(17) FIGS. 4 and 5 show another panel 25 according to the invention. It is noted that constructural features similar or identical to those of panel 1 as described in FIGS. 1-3 will be referenced by the same reference number.

(18) In this case the terrace 15 is provided with embosses 26 and 27 extending adjacent and beneath the free end part 10 of the tab 4. The embosses 26 and 27 have an elongated and curved structure adapted to the structure of the free end part 10. As shown more clearly in FIG. 7, the embosses 26 and 27 comprise an outer emboss part 28 extending adjacent to the rear tab part 10, and an emboss part 29 extending beneath the rear tab part 10. Thus, the rear tab part is nested in the embosses 26 and 27. Again, the spacing between the embosses 26 and 27 is such that hooking or engagement with an external can structure is avoided. Also is avoided a hooking or engagement along the lateral part of the rear tab part 10.

(19) FIGS. 6 and 7 show another panel 30 according to the invention. The panel 30 comprises prevention means 16 according to the invention which have the form of dimples 31 (in total 8) extending adjacent to and along the rear tab part 10 of the tab 4. The height h of the dimples 31 is larger than the height of the underside of the rear tab part 10 but smaller than the height of the upper side of the rear tab part 10. Still, penetration of an external can structure is avoided along the entire outer circumference of the rear tab part 10. Obviously, and similar to the embodiments shown in FIGS. 1-7, the two middle dimples 31 may be removed in order to improve the finger access. Also, the dimples 31 may not only extend adjacent to the rear tab part 10 but may extend also only beneath the rear tab part, or both beneath and adjacent to the rear tab part 10. Still, under all situations the prevention means 16 avoid the engagement or hooking of the external can structure beneath rear tab part 10 of the tab 4. As shown in FIG. 8, the indent 32 extends only within the opening 11 of the tab and beneath the free end 12 of the rear tab part 10.

(20) FIGS. 8 and 9 show another panel 33 according to the invention. In this case, the panel 33 is provided with prevention means 16 in the form of an emboss 34 which is elongated and curved in shape, such that the emboss 34 extends generally and substantially along the rear tab part 10 inclusive the free end 12.

(21) FIG. 10 shows another panel 35 according to the invention. The panel 35 is provided in the central terrace 15 with prevention means 16 having the form of an emboss 36 which is curved and elongated, a emboss 37 having the form of a dimple 37, and an emboss 38 which is short elongated and straight. Still, the embosses 36-38 extend along the rear tab part 10 adjacent or at its outside. Between the embosses 36 and 37 is a spacing 39 allowing for a finger access where is also provided an indent 40. It is noted that the prevention means 16 are asymmetrical such that the finger access 41 is also asymmetric which may be elegant for promotion or particular advertisements such as pictures or illustrations formed in at least the central part 15.

(22) Finally, FIG. 11 shows the panel 1 mounted with its peripheral edge 2 on a container body 3. The container body 3 may have a bottom or may be without a bottom. With bottom it forms a container according to the invention, and without a bottom allows the filling of the container and subsequently closing the container after having been filled with a (non shown) bottom.

(23) The skilled will appreciate that the panel according to the invention is primarily made of metal, such as aluminum, steel and tinplate. But also suitable plastics or combination of plastic elements and metal elements are in principle suitable. Also the diameter and the thickness of the panel may be selected within wide ranges as long as the function and suitability is not hampered. Thus, a panel diameter in the range of 20-180 mm, such as 35 to 120 mm, like 96 mm is suitable. The thickness dependent on the type of material may be in the range of 0.10 to 2 mm, such as 0.18 to 1 mm or 0.22 to 0.8 mm.
