Definitions

  • the invention concerns a container with a barrel-like body and a fitting, sealed lid.
  • TFE tetrafluoroethylene
  • plastic containers for example comprising polypropylene
  • fiber drums for the packaging of polytetrafluoroethylene (PTFE) powders, because they afford a better surface quality and the operation of inserting an inner film or foil bag for protecting the powders can be avoided.
  • PTFE polytetrafluoroethylene
  • Containers for PTFE powder in their technically complicated, high-quality configurations are preferably produced by injection molding.
  • mass plastic materials such as polypropylene or polyethylene are used for reasons of price.
  • chemically modified propylene copolymers are preferably used as the material here.
  • the packaging systems are of high value so that the aim is to achieve re-use, for example by cleaning and re-filling.
  • the packaging system disclosed in EP-B-362 959 is a round three-component system comprising the container body, the lid and a clamping ring.
  • the sealing principle here provides that the upper part of the body terminates in an outwardly downwardly inclined configuration, whereas thin peripheral lugs in the inside edge of the lid are pressed on to the upper portion of the body by means of the clamping ring. The restoring moment of those peripheral lugs however is slight so that after the container has been first opened and re-closed, sealing integrity drops off severely. Re-use of the lid and recycling of the container is in practice not possible.
  • U.S. Pat. No. 4,674,650 describes a sealing arrangement for a round container of plastic material, comprising a container body, a lid and a clamping ring.
  • the seal is made by a sealing ring which is additionally fitted in the lid and which seals off the outwardly disposed, inwardly directed body.
  • Introducing an additional sealing ring comprising an elastic material suffers from various disadvantages: it makes the system more expensive, it causes increased difficulty in automatically cleaning off the packaging system prior to use, and upon disposal of the packaging system it has to be separated as an additional material component if the container material is to be fed to a recycling process.
  • a seal is made by an elastomer seal, for example of polyurethane, being cast into a groove provided in the lid. That elastomer seal seals against the upper edge of the body.
  • the essential disadvantage of that system is that the elastomer seal can be damaged under the loading pressure on the elastomer seal upon transportation and storage. Parts of the seal are detached and can pass into the PTFE powder to be protected. In this case also, the elastomer component has to be separated off if, after use of the packaging system, the container lids are fed to a recycling process.
  • the object of the present invention is to provide a container having a sealing means which excludes contamination of the content during transportation and storage, which permits multiple opening and closing without losses of sealing integrity and which manages without an elastomer seal as an additional material component.
  • the sealing locations are always of a peripherally extending closed configuration, irrespective of whether the basic shape of the container is round or polygonal.
  • the first sealing location is described in such a way that in that case the sealing surface (groove) is provided in the lid and the sealing leg or arm (upper edge of the wall of the body) is provided on the container, while that association is precisely the reversed in regard to the second sealing location (flange).
  • the association of the sealing surface and the sealing leg with the body and the lid respectively may also be reversed, that is to say for example the free upper end of the edge of the body can be grooved in a V-shape, in which a suitable projection on the lid could engage.
  • the distance can be put to use for length compensation purposes and thereby the sealing probability at both sealing locations can be enhanced. If in addition at least one of the sealing locations is divided into a plurality of partial sealing locations, that further enhances the sealing probability, even if the for example sealing legs of the partial sealing locations are not or scarcely movable relative to each other.
  • the first sealing location comprises the free upper end of the edge of the body, in the form of a sealing arm or leg, on to which fits a groove which is of preferably V-shaped cross-section and which is provided in the underside of the lid. That groove region of the lid, which forms the groove, goes radially inwardly into the main portion of the lid, the central region, and on the outside into a connecting region which, on the outside of the wall, is directed parallel thereto or inclinedly, for example with an increasing spacing, in an outward and downward direction.
  • the connecting region forms a transition into a lid edge which is of a fork-shaped or U-shaped cross-section with downwardly facing free ends, being the sealing legs.
  • Those sealing legs can be pressed with their free ends against an upwardly facing sealing surface, by means of a clamping device, which represents the top side of a flange which projects outwardly from the wall of the body.
  • the sealing surface which extends peripherally in a ring shape and against which the sealing leg or legs bear can extend horizontally, that is to say precisely perpendicularly to the longitudinal direction of the container, generally the axis of symmetry of the body and the lid, or inclinedly relative thereto, for example in such a way as to fall away radially inwardly, that is to say with an increasing spacing in the longitudinal direction with respect to the freely terminating edge of the body.
  • the lid and the body are pressed against each other, in particular at the two sealing locations, by a clamping device, frequently a clamping ring which embraces both the edge of the lid and also the adjacent flange of the body, in a radially inward direction.
  • the clamping ring has a radially inwardly open groove which is provided with inclined flanks and the inside surfaces of which become increasingly spaced from each other, from the bottom of the groove to the open end thereof, that is to say radially inwardly in the assembled condition thereof.
  • the probability of the two sealing locations bearing sealingly against each other is greatly increased by mobility of the elements forming the two sealing locations, either on the part of the lid or on the part of the body.
  • the annular flange is arranged between 10 mm and 100 mm, in particular 30 mm, below the edge of the body, and projects radially outwardly between 10 mm and 50 mm, in particular 20 mm.
  • the peripherally extending sealing legs which can be arranged on the annular flange of the body or at the edge of the lid are between 1 mm and 15 mm and in particular 3.5 mm high and between 1 mm and 10 mm and in particular 3 mm wide.
  • FIGS. 1 show the lid disposed on the body in the relaxed and in the braced condition with a large axial extent in respect of the lid
  • FIGS. 2 show the lid disposed on the body in the relaxed and in the braced condition with a small axial extent in respect of the lid
  • FIG. 3 show a third variant of the container.
  • FIGS. 1 and 2 respectively show in section along the longitudinal axis, the axis of symmetry 10 , of the body 1 and the lid 2 , the contact thereof against each other, more specifically in FIGS. 1 a and 2 a with the lid loosely fitted on the body and in FIGS. 1 b and 2 b with the lid braced against the body, with a clamping ring 3 serving as the clamping device.
  • both the lid and also the body, considered in plan, are symmetrical with respect to the axis of symmetry 10 which is intended at the same time to define the longitudinal direction, thereby forming peripherally closed containers, insofar as the single open end of the body can be sealingly closed by the lid.
  • the body and the lid are rotationally symmetrical.
  • the wall 7 of the body 1 is preferably of a smooth-surfaced nature on the inward side, for more easily filling, emptying and cleaning the interior of the container.
  • the body On the outward side, set back from the freely terminating edge 1 a of the body, the body has a peripherally extending annular flange 8 which projects radially outwardly.
  • the edge 1 a of the body that is to say the wall in particular above the annular flange, can be somewhat thicker in this respect than beneath the annular flange, but generally not thicker than 3 mm.
  • the lid 2 In cross-section in the radial region of the body edge 1 a, the lid 2 is of a U-shape or a V-shape with an annular groove 6 which is open downwardly, that is to say towards the body, and with which the lid 2 can be laid on the edge 1 of the body.
  • the lid forms a one-piece transition into a central region 2 d which is thus set downwardly with respect to the groove region 2 c.
  • the radially outward limb of the groove region 2 c is either prolonged in the axial direction or in an inclinedly outwardly enlarging configuration, by means of a connecting region 2 b.
  • the edge 2 a of the lid is provided in one piece at the lower outer free end of the connecting region 2 b. The edge 2 a of the lid is thus still disposed under the central region 2 d of the lid in the axial direction in the fitted condition.
  • the edge 2 a of the lid has sealing legs 11 b, 11 c which face downwardly and which terminate freely and which also again extend peripherally in a closed configuration.
  • the sealing action is to be implemented at two different sealing locations 4 , 5 ;
  • the freely terminating body edge 1 a which bears against the lid in the groove 6 thereof represents the first sealing location 4 .
  • the sealing legs 11 b, 11 c of the 11 d edge 2 a, which bear against the top side of the annular flange 8 of the body, represent the second sealing location which is subdivided into two partial sealing locations 5 a, 5 b by the sealing legs 11 b, 11 c which extend in mutually concentric relationship.
  • the bracing action is effected by virtue of the fact that, at the second sealing location 5 , the rear sides which respectively face away from the sealing location, more specifically the upwardly directed rear side 13 of the edge 2 a of the lid and the downwardly directed rear side 14 of the flange 8 , extend at an acute angle and come closer to each other as they extend in a radially outward direction.
  • the lid 2 is braced and sealed with respect to the body 1 by pushing on a clamping ring 3 with a suitably conical clamping groove 19 which is open in a radially inward direction and which is so dimensioned that, when the clamping ring 3 is pushed on, the clamping groove not only bears inwardly against the rear sides 13 , 14 of the edge 2 a of the lid and the flange 8 , but also presses them against each other in the axial direction.
  • the edge 2 a of the lid with its sealing legs 11 b, 11 c is relatively strong and stable in itself.
  • the groove region 2 c which for that purpose, in particular in the region of the bottom of the groove, can be of a wall thickness which is at least doubled in relation to the normal wall thickness for example of the central region 2 d, and in addition has an extension portion 2 e which affords an additional stabilising effect on the rear side of the groove, that is to say facing upwardly.
  • the edge 2 a of the lid is definitely movable with respect to the groove region 2 c, for example by virtue of a reduced thickness of material in the configuration therebetween, in particular at the respective transitions between the groove region 2 c and the connecting region 2 b, and the connecting region 2 b and the edge 2 a of the lid.
  • lid edge 2 a can be pivoted somewhat downwardly with respect to the connecting region or the entire connecting region can be pivoted somewhat radially inwardly with respect to the groove region.
  • edge 1 a of the body in particular the entire section of the wall 7 from the flange 8 to the free end, to be sufficiently strong and stable, and in particular to be thicker in wall thickness than the remainder of the wall 7 , so that the edge 1 a of the lid can admittedly be bent inwardly or outwardly at its free end in a radial direction, but only when a relatively large amount of force is applied.
  • the outwardly directed flange 8 is also of a very strong and stable nature, and in particular is stabilised by legs 15 which extend radially outwardly at the underside.
  • the clamping ring 3 comprises for example metal or plastic material and can be reduced in its diameter by tangentially fitted clamping screws, lever fasteners or others of the known possible options.
  • FIGS. 1 and 2 differ by virtue of the relationship of the spacings A and B respectively, to be defined hereinafter, in regard to the lid and the body:
  • spacings which are to be measured in the longitudinal direction are defined as follows in the unbraced rest condition of the body and the lid respectively: the spacing A in the case of the lid is the axial extent between the bottom of the groove 6 and the furthest downwardly projecting sealing leg 11 b, 11 c of the edge 2 a of the lid.
  • the spacing B in the case of the body is to be the spacing between the free upper end of the edge 1 a of the body and the upwardly facing sealing surface 12 b of the flange.
  • the spacing B is somewhat larger than the spacing A, this is precisely the opposite in FIG. 2 a.
  • Those differing relationships and the situations resulting therefrom can be deliberately selected or can occur by virtue of production tolerances in manufacture of the lid and the body respectively, which is generally implemented by an injection molding process.
  • the lid spacing A is greater than the body spacing B, as in FIG. 1 a, then when the lid is loosely fitted on to the body, the groove region 2 c thereof sits with a flank or the bottom of the groove 6 on the free, upwardly facing end of the edge 1 a of the body, without the downwardly facing sealing legs 11 b, 11 c of the edge 2 a of the lid reaching the upwardly facing sealing surface 12 b of the flange 8 , the sealing surface 12 b generally extending at a right angle to the axis of symmetry 10 .
  • the edge 1 a of the body does not lie in the bottom of the groove 6 of the lid 2 , but bears, spaced therefrom radially inwardly or preferably outwardly, against one of the flanks of the groove 6 , the spacing between the edge 2 a of the lid and the flange 8 at the second sealing location 5 becomes even greater.
  • FIG. 1 a shows, the lower free ends of the concentrically extending sealing legs 11 b, 11 c are not disposed in this case at one level, but, because of a slightly outwardly rising inclined position of the edge 2 a of the lid and also a slightly downwardly outwardly facing inclined position of the connecting region 2 b of the lid 2 , the radially inwardly disposed sealing leg 11 b extends somewhat further towards the sealing surface 12 .
  • the axial movement of the edge 2 a of the lid also provides that, at the first sealing location 4 , the groove 6 and in particular the contact point thereof at the flank is pressed against the edge 1 a of the body, and thus enhanced sealing integrity is also achieved at the first sealing location 4 .
  • the sealing surface 12 b does not extend perpendicularly to the axis of symmetry 10 but adopts a radially inwardly increasing spacing from the upper free end of the edge 1 a of the body, with the contact point under some circumstances moving in the direction of the bottom of the groove and the edge 1 a being slightly radially deformed, by virtue of an inclined positioning, as shown in broken line in FIG. 2 b, that axial bracing effect is still further increased.
  • the spacing A of the lid 2 is greater than the spacing B of the body 1 .
  • the edge 2 a of the lid lies on the sealing surface 12 b of the flange 8 and, because of the weight of the lid, the edge 2 a of the lid is thereby bent somewhat around the transition 18 to the connecting region 2 b, so that only the radially inward sealing leg 11 b will lie on the sealing surface and the radially outer sealing leg 11 b will be lifted somewhat off the sealing surface 12 b.
  • the bottom of the groove 6 will not reach the free end of the edge 1 a of the lid, unless it is not aligned in the radial direction with the bottom of the groove but is displaced radially outwardly or inwardly and thus already bears against one of the flanks of the groove 6 .
  • the edge 2 a of the lid is initially displaced radially inwardly along the sealing surface 12 b and, when that happens, it additionally also provides that both sealing legs 11 b, 11 c of the edge 2 a of the lid bear against the sealing surface 12 b of the flange 8 of the body 1 .
  • the connecting region 2 b which adjoins the edge 2 a of the lid is also displaced radially inwardly and thereby causes the edge 1 a of the body to bear at least against the radially outer flank of the groove 6 , and thus a sealing effect also occurs at that first sealing location 4 .
  • FIGS. 3 a and 3 b A further possible option is shown in FIGS. 3 a and 3 b:
  • the wall thickness of the edge 1 a of the body, at least at the free end thereof, is so great that it cannot in any way penetrate into the groove 6 so far that the bottom of the groove is reached.
  • the edge 1 a of the body already bears with its end region against both flanks of the groove 6 while the sealing legs 11 of the edge 2 a of the lid still do not reach the sealing surface 12 b of the flange 8 . It is only by pushing on the clamping ring as shown in FIG. 3 b that the edge 2 a of the lid is pulled radially inwardly, in particular however also in an axial direction downwardly on to the sealing surface 12 b against which the sealing legs 11 b, 11 c now bear. That axial bracing effect also causes the free end of the edge 1 a of the body to be pushed further into the groove 6 and also expanded slightly—depending on the respective stability of the groove region 2 c.
