Definitions

  • the invention relates to a can provided with an easy-open device, said can for instance being used for packing block articles, such as meat articles in blocks.
  • the object of the invention is to provide a can of the above type which completely eliminates the risk of the bottom of second can when piled atop another can unintentionally hits the easy-open device of the first can during the piling procedure whereby the latter can leaks.
  • the can according to the invention is characterised in that the cover panel comprises a score line placed adjacent a closing flange formed between the cover panel and the body of the can, and that the nose of a pull ring of the easy-open device is placed very close to said score line, and that upward projections are formed on the cover panel, and that the position and height of these projections are such that when a second correspond ⁇ ing can is piled atop the first can these projections abut the downward projection(s) on the bottom member of the second can. In this manner it is avoided that the second can comes into contact with the pull ring of the first can.
  • the easy-open device of the can such as a pull ring with a nose, is most probably kept clear of a possible impact effect from a second can in the moment said second can is piled atop the first can.
  • the risk of the first can accidentally starting to leak has therefore been highly reduced.
  • the body of the can may at the bottom be necked-in, whereas the height of the projections of the cover panel plus the height of the projections of the bottom member may be slightly higher than the height of the upward retracted portion of the bottom plus the thickness of the pull ring.
  • the resulting embodiment turned out to be particularly advantageous.
  • the projections may according to the invention be of an equal height with the result that the can is particularly simple to manufacture.
  • the pull ring may according to the invention be arranged on the longitudinal axis of the cover panel, whereas the projections of the cover panel are symmetrically arranged around the pull ring. In this manner the pull ring is protected in a particularly good manner against impacts "from the side" .
  • the projections may according to the invention be of a height of 1 to 6 mm, preferably 2 mm, which turned out to be particularly advan ⁇ tageous.
  • the can when presenting a circular cross section according to the invention be characterised in that the downward projections of the bottom member are annular, whereby it is ensured that the bottom mem- ber of a second can piled atop said first can most unlikely hits the pull ring or the nose of the first can during the piling procedure because said projec ⁇ tions always keep the cover panel of the first can and the lower end of the upward retracted portion of the bottom sufficiently interspaced.
  • Fig. 1 is a top plane view of a can according to the invention
  • Fig. 2 is a bottom plane view of the can of Fig. 1 ,
  • Fig. 3 illustrates two cans piled atop one another
  • Fig. 4 is a partially sectional view taken along the line IV-IV of Fig. 3,
  • Fig. 5 is a top view of a circular can
  • Fig. 6 is a bottom plane view of the can of Fig. 5.
  • the can D shown in the Figures comprises a cover panel 1 (Fig. 1 ), a bottom member 10 (Fig. 2), and a body 5 (Fig. 3).
  • the cover panel comprises a circumferential score line 2 adjacent a closing flange 6 formed between the cover panel 1 and the body of the can.
  • the cover panel comprises also an easy-open device 7, optionally provided with a pull ring 7a and a nose 7b.
  • the nose 7b is positioned very close to the score line 2.
  • the cover panel 1 comprises furthermore upward projections 8a, 8b, 8c, 8d. These projections are arranged in such a way and are of such a height a that when a second corresponding can D' is piled atop the cover panel 1 said projections abut one or more downward projections 9a, 9b, 9c, 9d, cf. Fig. 2, on the bottom member 10 of the can thereabove.
  • the easy-open device i.e. the pull ring and/or its nose, on the first can does not come into contact with the second can.
  • the body 5 can be "necked-in" at the bottom, cf. 1 1 '.
  • the height of the projections of the cover panel 1 is a
  • the height of the projections of the bottom member 10 is b
  • the height of the upward retracted portion of the bot ⁇ tom member is k
  • the height (the thickness) of the easy-open device is m
  • the projections 8a, 8b, 8c, 8d. are preferably of an equal height.
  • the projections 9a, 9b, 9c, 9d are also preferably of an equal height.
  • the height of the projections on the cover panel need not, however, be the same as the height of the projections on the bottom member.
  • the pull ring 7 is arranged on the longitudinal axis 21 of the cover panel, whereas the projections 8a, 8b, 8c, 8d are sym ⁇ metrically arranged around the pull ring.
  • the projections 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d can be of a height of 1 to 6 mm, such as 2 mm.
  • the can When the can is of a circular cross section, cf. Fig. 5, where the cover panel 1 1 of a circular can is shown, the projections 1 8a, 18b, 18c of the cover panel can be placed as shown, while the bottom member 20 of the can can comprise a downward projection 19, cf. Fig. 6.
  • the projection 1 9 presents a radius almost identical with the radius on which the projections 18a, 1 8b and 18c are arranged on the cover panel 1 1 .
  • An easy-open device 7 can be placed as illustrated in Fig. 5.
  • the height of each projection 1 8a, 1 8b, 1 8c. plus the height of the projection 1 9 is so large that a second round can piled atop the first round can is kept clear of the pull device 7 of the first can.
  • the can according to the invention can be used for packing many types of articles, but it turned out to be particularly suited for block articles, espe ⁇ cially meat articles in blocks.
  • the importance of the score line 2 being arranged close to the closing flange of the cover panel 1 is based on the fact that when the panel of the cover 1 is removed, the block article must be able to slide out of the can without being damaged by the closing flange remaining on the body of the can.

Abstract

La présente invention concerne une boîte de conserve pourvue d'un dispositif d'ouverture facile (7, 7a, 7b), utilisable pour emballer des articles solides, ladite boîte de conserve pouvant être munie d'un panneau couvercle (1). Ce panneau couvercle comporte une ligne de prédécoupe (2) à proximité d'un bourrelet (6) de fermeture formé à la jonction entre le panneau couvercle et le corps de la boîte de conserve. Le bec (7b) de l'anneau d'arrachage (7a) du dispositif d'arrachage est placé très près de la ligne de prédécoupe (2). Le panneau couvercle est pourvu de protubérances tournées vers le haut (8a, 8b, 8c, 8d). La position et la hauteur de ces protubérances sont prévues de façon que lorsqu'une deuxième boîte de conserve correspondante est empilée avec une première boîte, ces protubérances (8a, 8b, 8c, 8d) viennent au contact de protubérances tournées vers le bas et réalisées dans le fond de la deuxième boîte de conserve, ce qui empêche la deuxième boîte de conserve d'entrer au contact de l'anneau d'arrachage de la première boîte de conserve. De ce fait, on réduit fortement le risque que le bec vienne malencontreusement provoquer une fuite dans la première boîte de conserve.
