Definitions

  • the present invention relates to a circular cork closure member for closing a receptacle.
  • a field of application envisaged is in particular, but not exclusively, that of the storage of foodstuffs which should be preserved vis-à-vis the air outside the receptacle.
  • Known cork circular closure members make it possible, for example, to stop glass jars containing condiments.
  • the neck of the glass pot has a tapered lapping and the closure member is also conically shaped to engage in the conical lapping and thus seal the neck relatively tight manner.
  • the closure member comprises on the one hand a large diameter gripping portion having a gripping face and on the other hand a smaller diameter plugging portion having a closure face opposite to the gripping face.
  • the slices, gripping the gripping portion and plugging the capping portion, are conical and defined by the same conical surface.
  • the closure member is gripped by its gripping portion so as to engage the sealing portion inside the conical lapping of the neck of the glass jar.
  • the dimensions of the conical closure member are adapted vis-à-vis those of lapping conical to prevent it completely penetrates inside the pot. The closure member is then stuck in the neck as it engages and comes to seal it relatively tight.
  • the capping portion is of cylindrical symmetry for example, for cylindrical lapping glass container necks, the variability of dimensions of the diameter of this cylindrical portion leads to a sealing more or less well sealed.
  • a problem that arises and that aims to solve the present invention is to provide a closure member that allows to overcome the dimensional variability of a series of this closure member and those containers it is intended to close if necessary.
  • a circular cork closure member for closing the opening of a receptacle delimited by an inner edge
  • said closure member comprising on the one hand a gripping portion having a gripping face and a gripping edge, and secondly a plugging portion having a closure face opposite said gripping face and a plugging edge for engaging said inner edge, said plugging face.
  • said capping edge defining a common circular edge having a capping radius R b .
  • Said sealing portion has a recess opening out axially into said sealing face and extending radially up to a maximum radius R m less than said sealing radius R b, so as to release a free wing radially deformable circular.
  • a feature of the invention lies in the implementation of a recess of a given depth in the sealing portion for releasing a deformable circular free wing in a radial direction, compared to a solid cylinder much less compressible.
  • provision is made for the production of closure members whose dimensions of the closure part are appreciably higher on average, by compared to those of the opening of the receptacle.
  • the capping radius R b of the circular edge is substantially greater than that of the opening of the receptacle.
  • cork is a living material and the parts of a series machined in this material, have variable dimensions around an average, and of greater amplitude than another wood for example. These dimensional variations are also related to the ambient hygrometry and the initial drying of the cork.
  • the diameter of the opening of a series of these boxes is also variable around a mean value.
  • the average capping radius of the capping portion is substantially increased.
  • said recess extends radially between a minimum radius R i and said maximum radius R m .
  • the recess does not extend throughout the sealing portion so that the closure member retains its mechanical strength.
  • said closing portion has a circular groove of minimum radius R i and maximum radius R m forming said recess.
  • R i and maximum radius R m forming said recess.
  • the radial deformation of the circular free wing towards the center of the closing portion is controllable. Indeed, depending on the depth of the circular groove, and also its width, which then defines two opposite edges, the circular free wing can be deformed until it comes to a stop against the other groove edge, the most central.
  • the deformation amplitude of the deformable free wing is defined.
  • the maximum radius R m is determined the width of the free deformable wing and therefore its resistance to deformation. Indeed, for a given groove depth, the greater the thickness of the deformable free flange is large, the greater its mechanical strength is important. Conversely, the smaller the width of the deformable free wing, the lower the mechanical resistance to deformation.
  • the closure member comprises a shoulder between said plugging portion and said gripping portion.
  • the diameter of the gripping portion is thus greater than that of the sealing portion, the two parts being coaxial.
  • said capping slice has a groove.
  • the receptacle comprises a circular bulge extending protruding from the inner edge along the edge of the opening, and when the closure member is applied to the receptacle, the capping portion engaged with the internal border, the bulge comes into the throat.
  • the engagement of the bulge in the groove is facilitated by the implementation of the recess according to the invention because it allows the mobility of the circular free wing.
  • the circular free wing deforms radially in contact with the bulge and then returns to its initial position when the throat reaches the bulge.
  • said common circular edge has a chamfer.
  • the latter makes it easier to make the engagement part of the closure part inside the opening, especially when the internal edge has a bulge.
  • a cork board is provided; a straight circular cylindrical body comprising, on the one hand, a first portion intended to form a gripping part having a gripping surface and a gripping edge, and on the other hand an second portion intended to form a closure portion having a closure face opposite to said gripping face and a closure portion, said closure face and said closure portion defining a common circular edge having a closure radius R b ; and further is made in an axially opening recess said stopper portion in said face of plugging and extending radially up to a maximum radius R m less than said sealing radius R b, so as to release a deformable circular free wing radially.
  • a closure member obtained by such a method has the advantages described above.
  • said recess is practiced by extending radially between a minimum radius R i and said maximum radius R m .
  • a small portion of material is removed from the sealing portion.
  • a hole saw is provided to practice said recess.
  • the recess is made very easily at low cost.
  • said recess is made by means of a drill bit.
  • the Figure 1 illustrates a cork closure member 10 with a circular axis of symmetry A intended to plug a receptacle 12. Firstly, with reference to FIG. Figure 1 and at the Figure 4 , the method of producing the circular cork closure member 10.
  • a first step 14 cork planks having two substantially parallel opposite faces and a constant thickness at least equal to the thickness E of the closure member shown on the Figure 1 .
  • Cork boards can be made from natural cork or agglomerated cork.
  • a second step 16 is made by means of a casing punch, a straight circular cylindrical body of a diameter D at least equal to the diameter of the closure member 10 shown on the Figure 1 .
  • the right cylindrical body then defines a mean plane dividing it into two substantially identical circular portions.
  • the wafer of one of these two circular portions is machined, so as to bring its diameter to a smaller diameter d .
  • a shoulder 20 is then provided in the closure member 10. This shoulder delimits an upper gripping portion 22 of a lower closure portion 24.
  • the upper gripping portion 22 presents a gripping wafer 26, while the lower capping portion has a closure wafer 28.
  • This lower capping portion 24 delimited by its capping edge 28 then defines a capping radius R b .
  • the upper gripping portion 22 defines an upper gripping face 30, while the lower closing portion 24 defines a closing face 32 opposite to the gripping face 30.
  • the closure member 10 has the upper diameter D, while the lower closing portion 24 has the lower diameter d .
  • the shoulder 20 then appears between the gripping portion 22 and the sealing portion 24.
  • the sealing face 32 and the sealing portion 28 of the sealing portion 24 meet and define a stop forming a common circular edge 34 This circular edge 34 also has the capping radius R b .
  • a circular groove 38 is made, at a distance from the circular edge 34 and which is found on the Figures 1 and 2 .
  • This circular groove 38 is advantageously made by means of a hole saw adapted to cork.
  • the hole saw is equipped with diamonds to be able to cut the cork easily.
  • the circular groove 38 then defines a recess which extends axially and which is delimited radially by two opposite edges, 40, 42 whose maximum radius R m is smaller than the closure radius R b , and whose minimum radius R i is even lower than the maximum radius R m .
  • the circular groove 38 has a depth substantially close to the thickness ep of the sealing portion 24.
  • the common circular edge 34 is chamfered so as to facilitate the implementation of the closure member 10 which will be described hereinafter.
  • the Figure 1 also illustrates a cylindrical receptacle 48 made in a cellulosic material and having a receptacle edge 49 and an inner edge 50, along the edge 49 and defining an opening 52.
  • the inner diameter of the aperture 52 is then substantially less than the smaller diameter d of the closing portion 24 of the closure member 10.
  • the common circular edge 34 bears on the receptacle edge 49, while the circular free wing 44 is deformed radially towards the center C of the closure member 10 as the sealing portion 24 penetrates inside the receptacle 48 and the sealing portion 28 is driven axially in friction against the internal rim 50.
  • FIG. 3 illustrating according to a second embodiment, a closure member 10 'for closing a container 48'.
  • Elements similar to those of Figure 2 and playing the same role have the same reference assigned a "" sign.
  • the additional elements are assigned a reference taken in the continuity of the series of references already assigned.
  • the closure member 10 ' has a gripping portion 22' and a sealing portion 24 'delimited by a shoulder 20'.
  • the sealing portion 24 ' is delimited by its sealing portion 28' in which a groove 54 is made.
  • the sealing portion 24 ' has a sealing face 32' defining with the sealing edge 28 'a circular edge 34'.
  • the sealing portion 24 ' has a circular groove 38' forming a recess and opening axially into the sealing face 32 '.
  • the circular groove 38 ' extends radially to a maximum radius R' m less than the closure radius R ' b , so as to release a radially deformable radial free wing 44'.
  • the circular groove 38 ' extends radially towards the center C' of the closure member 10 'to a minimum radius R' i .
  • the receptacle 48 ' is also made of a cellulosic material and it has a receptacle edge 49' and an internal rim 50 ', along the edge 49' and defining an opening 52 '.
  • the receptacle 48 ' has a bulge 56 projecting from the inner rim 50' along the receptacle edge 49 '.
  • the bulge 56 is made of a rolled nip of the receptacle 48 '.
  • this second embodiment also, thanks to the circular groove 38 ', it is possible to accept a greater dimensional tolerance of the diameter of the openings 52' of the receptacles 48 '. And thus, it is expected to provide a series of receptacles whose opening diameter is on average smaller than the diameter required theoretically so as to ensure the perfect sealing of the closure of all receptacles series.
