Definitions

  • the invention relates to a container with a barrel-like body and a matching, tight lid.
  • TFE tetrafluoroethylene
  • plastic containers for example made of polypropylene
  • fiber drums for packaging polytetrafluoroethylene (PTFE) powders because they have a better surface finish and the insertion of a film inner bag to protect the powders can be omitted.
  • PTFE polytetrafluoroethylene
  • High demands are made of various types on the plastic containers: they must be sufficiently leak-proof, even if they are opened and closed several times. According to DE-U-94 08 630, they must also withstand the loading pressure that occurs when the filled containers are stacked on top of each other on the individual packaging units. In practice, two to four pallet stacks are stacked on top of each other, which in turn are loaded with two to three layers of containers. The containers are filled with 20 to 50 kg of powder. When filling, certain bulk heights in the container must not be exceeded, otherwise the powder can cake together and error-free processing cannot be guaranteed.
  • Containers for PTFE powder in their technically complicated, high-quality designs are preferably manufactured by injection molding.
  • Bulk plastics such as polypropylene or polyethylene are used for price reasons. Since a high level of stability of the containers during transport and storage is required, even at temperatures from -20 ° C to 60 ° C, chemically modified propylene copolymers are preferred as the material.
  • the packaging systems have a high value, so that reuse, for example by cleaning and refilling, is aimed for.
  • the packaging system according to EP-B-362 959 is a round three-component system consisting of a container body, lid and clamping ring.
  • the sealing principle consists in that the upper part of the body runs downwards inclined, whereas thin lugs in the inner edge of the lid are pressed onto the upper part of the body with the help of the clamping ring.
  • the resilience of these handling flags is low, so that after a first opening and reclosing, the tightness decreases significantly. Reusing the lid and recycling the container is practically impossible.
  • the manufacture of the sealing thin sealing lips by the injection molding process is technically very complex and prone to failure, since a complex venting must be available in the injection molding tool for the complete injection of the thin sealing lips.
  • polymeric deposits can lead to complete or partial clogging of the ventilation areas, which leads to incomplete spraying of the thin lugs and thus the sealing function is no longer guaranteed.
  • a seal for a round container made of plastic which consists of the container body, lid and clamping ring. Sealing is carried out by an additional sealing ring inserted in the cover, which seals the outer, downward-facing body.
  • the introduction of an additional sealing ring made of an elastic material has several disadvantages: it makes the system more expensive, makes automatic cleaning of the packaging system difficult before use, and must be separated as an additional material component when the packaging system is disposed of, if the container material is to be recycled.
  • the tightness is achieved by pouring an elastomer seal, for example made of polyurethane, into a groove in the lid.
  • This elastomer seal seals against the upper edge of the body.
  • the main disadvantage of this system is that the seal can be damaged under the load pressure of the elastomer seal during transport and storage. Parts of the seal are removed and can be in the PTFE powder to be protected reach.
  • the elastomer component must also be separated here if the container lids are sent to a recycling process after the packaging system has been used.
  • the first sealing point 4 Due to the axial spacing of the first sealing point 4 from the tensioning device 3, it can be designed in the area of the intermediate cover and / or body in such a way that it is elastically deformable between the relaxed and the tensioned state and the elastic restoring force ensures the tightness.
  • a second sealing point 5 can be arranged in the area of the tensioning device, so that overall a very high level of security of the seal is provided. Due to the cup-shaped, one-sided open container and matching lid, the sealing points are always closed all round, regardless of whether the basic shape of the container is round or polygonal.
  • the tensioning device is preferably formed in one piece with one of the container parts, preferably together with the lid, and is preferably not continuous over the circumference, but is provided at several separate locations, for example at four locations distributed by approximately 90 ° in each case.
  • the tensioning device consists of a radially strutting locking projection, which is preferably formed on the body and preferably consists of a continuous annular flange over the circumference, and a radially inward open recess, which is formed on the locking tabs of the cover for receiving the ring flange as a locking projection.
  • the latching tabs have a significantly smaller wall thickness in the area of the latching depressions, that is to say the bottom of the latching depression, than to the side next to the latching tabs. Since the radially protruding edge of the lid, which leads to the locking recess, has a relatively large material thickness, which preferably increases radially from the outside inwards, when the locking tabs 33 are bent radially outward to open the clamping device, the locking tabs 33 can preferably be located in the region of the small one Bend the material thickness, that is to say in the region of the groove base of the latching recess, or the circumferential cover edge as a whole in the connecting area axially above the latching recess 32.
  • first sealing point is described below in such a way that the sealing surface (groove) in the lid and the sealing web (upper edge of the body wall) are formed on the container, while this assignment is just reversed at the second sealing point (flange).
  • the assignment of the sealing surface and sealing web to the body or lid can also be reversed. be reversed, so for example the free upper end of the body edge can be V-shaped, in which a suitable projection of the lid could engage.
  • the body and lid can be juxtaposed at the sealing points directly, i.e. without the interposition of a special, more elastic sealing material, with the advantage of one Easier recyclability and a reduced risk of contamination of the contents due to detachable components of the sealing material.
  • the sealing points By sufficient axial spacing of the sealing points, the distance for diameter and / or length compensation can be used and the sealing probability at both sealing points can thereby be increased. If, in addition, at least one of the sealing points is divided into several partial sealing points, the sealing probability is further increased, even if the z. B. sealing webs of the partial sealing points are not or hardly movable relative to each other.
  • the first sealing point consists of the free upper end of the body edge as a sealing web on which a groove formed in the underside of the cover and preferably having a V-shaped cross-section is seated.
  • the diameter of the upper end of the body edge is slightly larger than the diameter of the groove in the lid, so that the axial Pressing on the lid, the flank of the groove presses the body edge radially inwards and possibly deforms it elastically.
  • This groove forming the groove area of the cover goes radially inward into the main part of the cover, the central area over and on the outside in a connecting area, which is parallel to this or obliquely on the outside of the wall, z.

  • the rear sides facing away from the sealing surface of both the lid edge and the flange are also formed obliquely:
  • the upward-facing rear of the edge of the lid thus falls obliquely downwards from the inside, while the downward-facing rear of the flange rises obliquely from the inside outwards, corresponding to the inclination of the inner flanks of the locking recess of the clamping ring.
  • the ring flange is arranged 10 mm to 100 mm, in particular 30 mm, under the body edge and projects 10 mm to 50 mm, in particular 20 mm, radially outwards.
  • the circumferential sealing webs which can be arranged on the ring flange of the body or on the edge of the lid, are 1 mm to 15 mm, in particular 3.5 mm, high and 1 to 10 mm, in particular 3 mm, wide.

  • Figures c and d are steps in the area of the latching tabs, figures a and b in the circumferential area in between, as can be seen in FIG. 4.
  • FIGS. 1 to 3 Common to the designs of FIGS. 1 to 3 is the basic design of the cross-sectional shape of the cover, in particular the edge of the cover, and the upper region of the wall of the body 1: when viewed from above, both the cover and the body are symmetrical with respect to the axis of symmetry 10, which at the same time should define the longitudinal direction 20, so that all-round closed containers are formed in that the only open side of the body can be sealed by the lid. As a rule, the body and lid are rotationally symmetrical.
  • the wall 7 of the body 1 is preferably smooth on the inside, for easier filling, emptying and cleaning of the inside of the container.
  • the body 1 On the outside, axially set back and also radially outwardly spaced from the free-ended body edge 1a, the body 1 has a circumferential ring flange 8 which projects radially outwards and is also lower than the central region of the cover 2.
  • the body edge 1a that is to say the wall, in particular above the ring flange, can be made somewhat thicker than below the ring flange, but generally not thicker than 3 mm.

  • the cover merges in one piece into its central area 2d, which is thus lowered relative to the groove area 2c.
  • the radially outer leg of the groove area 2c is extended either in the axial direction or obliquely outwards by means of a connecting area 2b, at the lower outer free end of which the lid edge 2a is in one piece. This is located in the axial direction in the attached state, thus still under the central area 2d of the cover.
  • a total of 4 latching tabs 33 project further downward in the axial direction from the purely outer end of the lid edge 2a. These serve for locking with the ring flange 8, whereby the cover is held tightly against the body in the locked state.
  • the cover edge 2a has a downward direction and radially concentric sealing webs 11b, 11c all around the locking tabs 33, which, however, in a preferred embodiment only run concentrically to one another in the area between the locking tabs 33, and in the circumferential area of the locking tabs 33 to form a single sealing web 11b 'are summarized, the radial width of which is preferably the total width of the sealing webs 11b, 11c including their mutual spacing. If the cover is clamped in relation to the body, the sealing should take place at at least the first, preferably two different sealing points 4, 5:

  • the bracing by means of the locking tabs takes place in that - as can be seen in Figures c and d in each case - the locking tabs 33 have a radially inwardly open locking recess 32, which is arranged directly below the sealing web 11b 'and the shape and dimension of the cross section of the correspond radially free outer end of the ring flange 8, which is preferably not ribbed in this area, but is solid.

  • the radially inner side of the thickening thus forms an oblique guide surface 35, on which the radially outermost edge of the ring flange 8 slides along when the cover is pressed on from above, thereby bending the latching tab 33 radially outward until the lower thickening snaps over the ring flange 8 and the latter engages in the locking recess 32 of the locking tab 33.
  • the thinner, free end 34 of the latching tab 33 protruding downward beyond the thickening serves - also because of the sufficient distance to the outside of the wall of the body 1 - for reaching behind with one finger for the radial outward pulling and thus releasing the cover 2.

  • the lid edge 2a is quite movable with respect to the groove area 2c, for example due to the reduced material thickness in the course therebetween, in particular at the transition between the groove area 2c and the connection area 2b and the connection area 2b and the lid edge 2a.
  • the lid edge 2a can be bent slightly downward relative to the connection area or the entire connection area can be pressed somewhat radially inward relative to the groove area.
  • the body edge 1a in particular the entire piece of the wall 7 from the flange 8 to the free end, is sufficiently stable, and in particular the wall thickness is thicker than the rest of the wall 7, and thus the body edge 1a its free end can be bent radially inwards or outwards, but only with relatively great effort.
  • the outwardly directed flange 8 is also very stable, and in particular is stabilized by webs 15 running radially outward on the underside.
  • the flange 8 preferably has a horizontally extending upper side as a sealing surface 12b, while the lower side 14 slopes away from the outside inwards.
  • the cross-section of the ring flange 8 is preferably solid, in the other circumferential areas it is formed by ribs 15 which are radially spaced over the circumference.
  • the ring flange 8 can be stiffened by vertical stabilizing webs 21 which protrude outwards from the wall of the body 1, as can best be seen in FIG. 4, and then merge into the ring flange 8 at the upper end, but freely run out at the lower end.
  • the stabilizing webs 21 protrude radially outward only to such an extent that they do not hinder reaching around the outer free end of the ring flange 8 by the latching tab 33, and are preferably also in the areas of the circumference which serve to place the latching tabs 33 in see the peripheral areas in between, usually evenly distributed.
  • Figures 1 to 3 differ in the relation of the distances A and B to be defined below for the lid and body:
  • Distance A in the cover is the axial extent between the base of the groove 6 and the sealing web 11b which projects the most downward , 11c of the lid edge 2a.
  • distance B is the distance between the free upper end of the body edge 1a and the upward-facing sealing surface 12b of the flange 8.
  • the cover 2 lies tightly in the groove 6 of the cover 2 at the first sealing point 4. This sealing can be supported by the second sealing point 5 on the ring flange 8.
  • lid spacing A is smaller than the body spacing B, as in FIG. 1, when the lid is loosely placed, its groove area 2c sits with a flank or the groove bottom of the groove 6 on the free, upward-facing end of the body edge 1a without the downward-pointing sealing webs 11b, 11c of the cover edge 2a reach the upward-pointing sealing surface 12b of the flange 8, which is generally at right angles to the axis of symmetry 10.
  • the distance between the sealing webs 11b ', 11b, 11c of the lid edge 2a and the flange 8 at the second sealing point 5 may be even larger.
  • Sealing webs 11b, 11c not at one height, but because of a slightly outward inclined position of the lid edge 2a and also a slightly downward outward inclined position of the connecting area 2b of the Cover 2, the radially inner sealing web 11b extends somewhat further towards the sealing surface 12.
  • latching tabs 33 radially inward as far as possible and also increasingly downward because of the oblique underside of the ring flange 8.
  • the lid edge 2a is moved radially inward on the one hand and, on the other hand, simultaneously and / or instead pressed axially against the sealing surface 12b of the flange, that is to say downwards. This is due to the mobility of the lid edge 2a relative to the rest of the lid 2, in particular with respect to the groove area 2c, and in particular due to a
  • the sealing webs 11b, 11c - in the tab area of the sealing web 11b '- reaches the sealing surface 12b with its free end of the flange 8, whereby an additional seal is achieved at this second sealing point 5.
  • the radially outer sealing web 11c lies with its entire end face against the sealing surface 12b, while the radially inner sealing web 11b has only line contact with the sealing surface 11b.
  • the groove 6, in particular its contact point on the flank, is also pressed against the body edge 1a at the first sealing point 4, and thus an increased tightness is also achieved at the first sealing point 4.
  • the body edge 1a has a slightly larger diameter than the groove base of the groove 6, the body edge 1a is additionally deformed somewhat radially inwards when the cover 2 is pressed on at its free end, such as, for. B. in Fig. 1b, so that the elastic restoring force of the body edge 1a in the relaxed rest position additionally increases the tightness at this first sealing point 4.
  • the sealing surface 12b does not run perpendicular to the axis of symmetry 10, but rather an increasing distance from the radially outside to the radially inside, the contact point possibly moving in the direction of the groove base and the edge 1a being slightly radially deformed, taking up from the upper free end of the body edge 1a Due to an inclination, as shown in dashed lines in Fig. 2b, this axial bracing effect is further increased.
  • the distance A of the lid 2 is greater than the distance B of the lid 1.
  • the lid edge 2a thus lies on the sealing surface 12b of the flange 8, and because of the weight of the lid this causes the edge of the cover 2a to bend slightly around the transition 18 to the connection region 2b, so that only the radially inner sealing web 11b is in contact and the radially outer sealing web 11c will be slightly raised from the sealing surface 12b.
  • the groove base of the groove 6 will furthermore not reach the free end of the edge of the cover 1a, unless this is not aligned in the radial direction with the base of the groove, but is radially outward - which is the preferred design - or offset on the inside and is therefore already on one of the flanks of the groove 6.
  • the lid edge 2a is initially displaced radially inward along the sealing surface 12b, and in addition thereby also causes both sealing webs 11b, 11c of the lid edge 2a on the sealing surface 12b of the web 8 of the body 1 rest.
  • the connecting region 2b adjoining the lid edge 2a is also displaced radially inward and, as a result, the body edge 1a bears at least on the radially outer flank of the groove 6 - possibly with radial elastic deformation of the body edge 1a inward -, and thus also occurs at this first sealing point 4.
  • FIG. 3 Another possibility is shown in FIG. 3:
  • the wall thickness of the body edge 1a, at least at its free end, is so large that it cannot penetrate into the groove 6 to such an extent that the bottom of the groove is reached.
  • the body edge 1a thus already lies with its end region on both flanks of the groove 6, while the sealing webs 11 of the lid edge 2a do not yet reach the sealing surface 12b of the flange 8. Only by fitting and latching the latching tabs 33 according to FIG. 3d is the lid edge 2a drawn radially inwards, but above all in the axial direction downward onto the sealing surface 12b, on which the sealing webs 11b, 11c now rest. As a result of this axial bracing, the free end of the body edge 1a is also pushed further into the groove 6, and this is also widened slightly, depending on the stability of the groove area 2c.
  • the stabilizing webs 22 on the cover 2 can also be seen, which extend radially and are distributed over the circumference between the highest elevation of the groove area 2c Cover 2 and the lowered central area 2d.
  • These stabilizing webs 22 are also formed in one piece with the cover 2, as are the latching tabs 33. The same applies to the stabilizing webs 21 of the body 1.
  • Fig. 4 shows in the broken area of the lid 2 and Figures 1a, 1b that the body edge 1a can be supported on the outside by additional stabilizing webs 23 which run radially and at an angle between the outside of the body edge 1a and the upward directed sealing surface 12b of the ring flange 8 are.
  • the radial extension outwards and upwards in the direction of the free end of the body edge 1a must be limited so that these stabilizing webs 23 do not impede a complete snap-on of the cover 2, including the snap-in tabs 33.
