Definitions

  • the present invention relates to a can, and to a body and a panel therefore.
  • This can according to the invention may be of the type having a so-called easy opening closure.
  • An easy opening closure is a metal closure for a can in which an opening may be formed by using one or more fingers and without the, requirement of a separate opening tool. To that extent the can is provided with a tab for forming an opening in the panel of the can. The tab functions as a lever.
  • the tab comprises a rear tab part which is to be gripped by the user.
  • the front tab part is actuated.
  • Actuation by levering or tilting results in popping an initial opening in the panel.
  • the opening is defined by a score line.
  • the score line is generally circumferential. With the tab in an upright position a maximum popping opening is formed. Tearing the tab outwardly results in scoring out of the panel. Finally, by hinging the panel is torn apart from the can and the can opening is formed.
  • the can according to the invention may also be provided with a smaller opening by the levering action of the tab, thereby forming a small opening just sufficient for emptying the content of the can.
  • the invention has for its object to improve the initial gripping action by the user. This improvement is under the condition that other functions of the can and tab are not influenced, such as the manufacture, filling, handling and opening of the can by the tab.
  • the present invention is based on the insight that cans may have, after filling and closure, an internal pressure, which is different from the surrounding atmospheric pressure.
  • Such negative pressure difference may be the result of hot filling and/or cooking of the content of the can before closing it.
  • After closure and cooling the gas phase above the content will reduce in volume, thereby forming a negative pressure difference over the panel and the surrounding.
  • a positive pressure difference may result from a permanent or transitional pressure build up after closure due to desired or unwanted gas generation and/or volume expansion due to heating.
  • This pressure difference is used to have the panel acquire a depressed or concave form at least beneath the rear tab part.
  • This depressed or concave forms result in an increase of the space beneath the rear tab part.
  • the increased space improves the gripping action.
  • this panel change occurs after manufacture of can and panel, after filling and closing. There is substantially no interference with the traditional handling of such cans.
  • the change from the concave form into the convex form may occur as a result the changed pressure difference.
  • the invention also encompasses the alternative after the change in pressure the changed in form does not yet take place but requires an impact from the outside, such as a mechanical contact or other physical means (magnets) by which the change in from will be facilitated.
  • the panel when the pressure difference is substantially zero the panel may be in the concave or convex form dependent on the structure of the panel.
  • the pressure difference may result from internal and external pressures of which one or both are above or below atmospheric pressure.
  • the panel At zero pressure difference the panel may be in a concave or convex form.
  • the present invention provides a can, comprising a body provided with a panel, wherein the panel is provided with a tab comprising a front tab part and a rear tab part for gripping in forming by engagement of the front tab part with the panel of an opening in the panel, wherein the panel is provided with a flip panel area at least beneath the rear tab part, which panel area forms a depression beneath the rear tab part, which depression preferably has a concave form dependent on a pressure difference over the panel.
  • the flip panel may be formed by providing the panel with a particular material (such as steel and aluminium), structure and/or by providing the panel in the flip panel area with a different thickness.
  • the main influence factor, from all the material properties, is the Young modules (elastic).
  • two panel geometries may be identical but due to different manufacturing methods, their residual stress fields may be different which interacts with material properties.
  • the flip panel area has a higher flexibility than other parts of the panel such that by the pressure difference the concave form beneath the rear tab part is provided.
  • jars, cans and bottles for fruit juice and marmalades may be provided with a screw cap having a similar flip panel area. However, these screw caps are not provided with a tab.
  • the flip panel area flips between a concave form and a flat form dependent on the pressure difference over the panel.
  • the flip panel parts flips from a concave form to a substantially flap form.
  • the flip panel area flips between a concave form and a convex form dependent on a pressure over the panel.
  • the provision of a convex form to the flip panel part does not interfere with the opening action using the tab because the tab is than in a more tilted position remote from the flip panel area.
  • the pressure difference may be
  • the flip panel area is part of a terrace structure. Accordingly, there is a better controlled area in the terrace structure in which the flipping of the flip panel part could take place. In this respect it is preferred on a consumer perspective that the flip panel area is a central terrace structure.
  • the panel is provided with a slanted or gradually depressing form (when the pressure difference exists).
  • the pressure difference when the pressure difference is completely or partially neutralized the flip panel area flips from the slanted concave form to a flat or convex form.
  • the tab movement is limited by a panel rest structure.
  • the panel structure has the form of a dimple on which the tab may rest or by which dimple the downward movement of the tab part is limited.
  • the flip panel area is located in the central panel part, other locations off-centered are also suitable.
  • the pressure difference at which the transition from convex to concave occurs is preferably a negative pressure difference.
  • the panel may be connected to the body of the can by any known means.
  • the panel may be unitary with the body or may be connected by any means, such as soldering, seaming and the like. It is preferred that the panel is seamed to the can body.
  • An other aspect of the present invention relates to a body provided with a panel having a flip panel area, which has a concave form dependent on the pressure difference over the panel.
  • a last aspect of the invention relates to a panel which has a flip panel area which has a concave form dependent on a pressure over the panel when part of a can described above.

  • the tab 6 is connected to the top panel 3 via a rivet 10 .
  • Other methods for connection of the tab 6 include welding with metal or plastic welding material.
  • the rivet 10 may be a separate rivet or may have been formed of material originating from the top panel and formed into a rivet shape.
  • the panel is provided with a score line 11 which is having a circular form.
  • the score line defines the opening in the can 1 .
  • the can is opened by inserting a finger or nail beneath the rear tab part 8 in a so called gripping space 12 . Levering or tilting the tab 6 results in a popping at the front tab part 7 in the score line 11 by a movement illustrated in FIG. 2B .
  • FIG. 2A shows more in detail and in cross section the top panel 3 according to the invention.
  • the top panel 3 is provided with a terrace structure 13 having three concentric terrace rings 14 - 16 at a lower position relative to the seam 5 .
  • the terrace structure comprises a central area, which is a flip panel area 17 according to the invention.
  • the flip panel area 17 has a concave structure for reasons that there exists a negative pressure difference over the panel from the inside to the outside. That is, the atmospheric pressure at the outside is higher than the internal pressure at the interior 18 of the can 1 according to the invention.
  • FIGS. 3A and 3B show an alternative of the can 21 according to the invention.
  • the can is provided with a panel 22 having a slanted form.
  • the panel has a central area 23 (at least beneath the rear tab part 8 of the tab 6 ), thereby forming the gripping space 12 under the rear tab part 8 .
  • the panel 23 is soldered to the body 24 . Due to the hot content of the can 21 after closure there will be an internal pressure which is lower than the atmospheric pressure and accordingly there is a negative pressure difference over the panel 22 . Due to this negative pressure difference the flip panel part 23 has a concave form.
