Definitions

  • the invention relates to a can made of metal or plastic according to the preamble of patent claim 1.
  • An object of the present invention is to provide a can which protects the contents both before the first partial removal of contents and then against the ingress of atmospheric oxygen, but at overpressure, either by fermentation or heat-related increase in volume of the air within the can allows a blow-off of gas from the inside of the can into the environment and after blowing safely prevents the ingress of oxygen from the environment even at temperature-induced negative pressure in the can.
  • annular sealing element With an annular sealing element with an axially acting seal and a radially outwardly directed sealing lip, it is possible to blow off pressure from the can and at the same time if there is a negative pressure inside the can to prevent the ingress of outside air.
  • suitable design and dimensioning of the thread means the blow-off pressure can be adjusted.
  • the very elastic axially acting sealing element retains its properties even after repeated opening and closing of the can.
  • FIG. 2 is a side view of the can lid
  • FIG. 3 is a side view of the container part
  • FIG. 4 is an axial partial section through the can with the lid on
  • FIG. 5 is an axial section through a can in a further embodiment of the invention
  • FIG. 6 is a side view of the can in FIG. 8 shows an axial section through a box in a further embodiment of the invention
  • FIG. 9 shows a side view of the box in FIG. 8
  • FIG. 10 shows an enlarged view of the box Edge region of the box in cross section (detail B in Figure 8).
  • Reference numeral 1 denotes a box in the figures. This comprises a bottom of the can, briefly called container 3, and a lid 5.
  • the cylindrical container 3 in the example is retracted in the region of its upper edge 7, ie the diameter of the container 3 is lower in the region of the upper edge 7 than in the lower part. Between the retracted area and the lower part, this creates a step or step 9.
  • the upper edge of the container 3 is formed into a rolled edge 11. That is, the edge is approximately oval shaped by a forming process in cross section.
  • the lid 5 comprises a lid surface 13 which spans the opening of the container 3.
  • a cylindrically extending collar 15 is externally mounted, in which locking cams or threads 17 are formed by plastic deformation.
  • the free edge 10 of the collar 15 is preferably turned over in order to guide the edge region, which may be sharp-edged by the trimming, out of the contact region when the cover 5 is opened.
  • the locking cams or threads 17 on the collar 15 mesh with latching projections or threaded sections 21 on the recessed area of the container 1 (see FIG. 4).
  • a sealing element 25 is inserted in a circumferential bead 23 in the peripheral region of the lid surface.
  • This The root of the sealing lip 29 is located in the region of the smallest diameter of the annular support body 27.
  • the free edge 31 of the sealing lip 29 is substantially radially to directed outside.
  • the relaxed seal member 25 has an axial height Ji. 1
  • the completely axially compressed sealing element 25 (not shown) has an axial height h 2 . In axially together completely pressed sealing element 25 the sealing lip 29 comes into contact with the supporting body 27.
  • the distance between the underside of the lid surface 13 and the vertex S corresponds to the rolled rim 11 of height h x of In this position, the free edge 31 of the sealing lip 29 is substantially without pressure on the vertex S of the rolling edge 11 at.
  • the lid 5 is pulled to close the container 3 by a rotation of the thread, ie the cooperating locking cams or threads 17 and the RastvorSprünge or threaded portions 21 or by axially pressing the lid 5 via the locking projections or threads 21, axially downwards.
  • the sealing element 25 and the sealing lip 29 is pressed against the vertex S of the rolled edge 11.
  • the distance s is between the lower free Edge 19 on the collar 15 of the lid 5 and the step 9 on the container 1 defined such that the free edge 31 of the sealing lip 29 is pressed with a precisely defined force at the apex S.
  • the radially outwardly bent sealing lip 29 seen in cross-section is loaded only axially by the contact pressure of the cover 5 in the absence of a pressure difference between the atmospheric pressure p 0 and internal pressure P 1 .
  • a gas exchange between the container interior and the atmosphere does not take place.
  • At elevated internal pressure for example by fermentation of the contents or increase in volume due to temperature increase, can escape between the apex S of the rolling edge 11 on the container 3 gas to the outside, since the sealing lip 29 is raised by the force acting in the interior of greater pressure.
  • An increased external pressure Po compared to the internal pressure P 1 causes an increased pressing of the sealing lip 29 on the apex S, since the sealing lip 29 can not escape. This ensures that buckling of the lid surface 13 can be avoided at elevated internal pressure P 1 .
  • the inventive container 1 may be made of metal or plastic. It is also a combination of a metal container 3 with a lid 5 made of plastic possible.
  • the sealing element 25 may be loosely inserted into the bead 23 in the lid 5 or secured therein with an adhesive.
  • the sealing element 25 is no longer used in the lid 5, but it is part of an inner container 33, which is inserted into the outer box 1.
  • the inner container 33 may alternatively consist only of a substantially cylindrical jacket-shaped insert part, which has no bottom, but is supported on the bottom of the container 3 (not shown).
  • the sealing element 25 is formed in the upper region. It comprises the radially outwardly directed sealing lip 29, which comes into contact with the cover surface.
  • the inner container 33 can simultaneously act as a connection between the container 3 and the lid 5.
  • a circumferential groove or a recess 37 is formed on the periphery of the inner container 33.
  • a first roller bead 39 engage the container 3 and a second roller bead 41 on the lid 5 a.
  • the container 3 is made of plastic.
  • the sealing element 25 is attached to the sealing lip 29 by suitable means.
  • a groove 45 widening towards its base is formed in the upper edge 43, into which groove a corresponding rib 47 on the sealing element 25 engages and snaps.
  • This design makes it possible to produce the container 3 from a plastic that is harder than the plastic from which the sealing element 25 is made.
  • the container 3 or the inner container 33 can be produced with the sealing element 25 in the 2K injection process, so that subsequent joining of the sealing element 25 and the container 3 is omitted.
  • the cover 5 engages below a bead 49 at the periphery of the container 3 made of plastic.

Abstract

L’invention concerne une boîte (1) en métal ou en matière plastique qui comprend un couvercle (5) muni d’un élément d’étanchéité (25) de forme annulaire. Sur celui-ci est façonnée une lèvre d’étanchéité (29) pour l’essentiel dirigée vers l’extérieur dans le sens radial. Lors de la fermeture et du blocage par rotation du couvercle (5), cette dernière vient s’appuyer contre le sommet (S) sur le bord supérieur du récipient (3). En cas de surpression dans la boîte (1), du gaz peut s’échapper vers l’extérieur en soulevant la lèvre d’étanchéité (29). Si la pression extérieure p0 est plus élevée, la lèvre d’étanchéité (29) est plus fermement poussée contre le récipient (3) et empêche la pénétration d’air.
