Definitions

  • This invention relates to a cover intended for a holder, which holder comprises a bottom and a casing wall, and an upper edge intended for engagement of the cover, the casing wall having connected thereto, adjacent the upper edge, a holder flange extending substantially perpendicularly to the casing wall, the cover comprising a cover wall which is provided at a circumferential edge with a closing wall which extends in a downward direction and which through a side proximal to the cover wall engages the upper edge, the closing wall being provided with a downward edge which, in a condition of the cover when placed on the holder, lies so closely against the holder flange extending perpendicularly to the casing wall, or is so screened by the casing wall or a wall portion extending substantially parallel to the casing wall, that engagement of this downward edge is not possible.
  • Such a cover, together with a holder designed as a bucket, is described, for instance, in applicant's European patent application EP-A-0 855 347.
  • the holder of the assembly is provided with a sealing lip which can be broken away, so that the user can grip the downward edge of the closing wall of the cover for the purpose of opening the cover.
  • breaking away the sealing hardly causes any weakening of the holder, this danger is nonetheless still present.
  • the invention contemplates a cover of the type described in the preamble, intended for a holder, which does not require breaking away any parts of the holder for taking the cover off the holder, so that the holder retains its original stiffness while yet a sealing can be provided.
  • the cover of the type described in the preamble is characterized in that at an engagement position, engagement of the downward edge is not possible, while at the engagement position an engagement lip is connected with the closing wall, which engagement lip is readily engageable and which upon engagement extends from the closing wall such that in a natural manner the detachment of the cover from the holder is efficiently effected. Because the downward edge of the closing wall is not engageable at any point, the user, for the purpose of opening the cover, will have to pull the engagement lip, so that the closing wall adjacent the engagement lip is rendered clear of the upper edge of the holder, whereafter the cover can be pulled loose from the holder.
  • the holder flange, and the wall portion possibly connected with the holder flange, can extend throughout the entire circumference of the holder without an interruption or any change in profile needing to be provided therein for the purpose of forming a sealing lip.
  • the holder will therefore have substantially the same stiffness throughout its circumference .
  • the weakening provisions mentioned will be broken, which breakage is visible, so that it is clear that the cover has been taken off the holder before.
  • the weakening provisions therefore have the sealing function that is such great importance in view of any improper opening of the assembly according to the invention.
  • the closing wall is broken, so that the force to be applied for taking the cover off the upper edge is considerably reduced.
  • the weakening provisions will not break and the cover can be opened without this leaving any traces.
  • the cover known from the Utility model mentioned is not provided with a engagement lip, let alone an engagement lip which upon engagement extends from the closing wall such that in a natural way the detachment of the cover from the holder is efficiently effected.
  • the cover can be provided with a sealing bridge at the engagement position, which sealing bridge is connected with the closing wall and optionally with the engagement lip, so that upon engagement of the engagement lip at least one of the connections of the sealing bridge with the closing wall or with the engagement lip is broken.
  • a sealing bridge at the engagement position, which sealing bridge is connected with the closing wall and optionally with the engagement lip, so that upon engagement of the engagement lip at least one of the connections of the sealing bridge with the closing wall or with the engagement lip is broken.
  • the invention further relates to an assembly of a cover according to the invention and a holder.
  • the holder can be designed as a bucket, which is made, for instance, from plastic, or as a can which is made from metal and which is provided with a double upper edge at the top.
  • the closing wall of the cover then falls between the casing wall and a wall portion connected with the holder flange, extending parallel to the casing wall.

  • All covers D shown in the exemplary embodiments are manufactured from plastic. Other materials for the manufacture of the holder and/or the cover, however, are also options.
  • Fig. 4 shows in cross section a complete assembly of a holder E and a cover D.
  • the holder E comprises a bottom 1 and a casing wall 2.
  • a holder flange 4 Provided adjacent an upper edge 3 of the casing wall 2 is a holder flange 4 extending substantially perpendicularly to the casing wall 2.
  • the cover D comprises a cover wall 7. At its circumference, the cover D is provided with a closing wall 8, which extends in a downward direction and, by way of a side thereof proximal to the cover wall 7, engages the upper edge 3 of the holder E, which upper edge 3 in this case is formed by the upper edge 3 of the casing wall 2.
  • the closing wall 8 is provided with a downward edge 8a which, in a condition of the cover D when placed on the holder E, lies so closely against the bucket flange 4 extending perpendicularly to the casing wall 2, or is so screened by the wall part 5 extending substantially parallel to the casing wall 2, that engagement of this downward edge 8a is not possible.
  • the downward edge 8a of the closing wall 8 is connected, at an engagement position, with an engagement lip 9 which extends from the downward edge 8a so as to be engageable.
  • such engagement occurs by the fingers, but 'engageable' is to be understood to include engageable with a tool, such as pliers or a screwdriver.
  • a tool such as pliers or a screwdriver.

  • Figs. 8 and 9 show the engagement lip 9 in top plan view and side elevation, respectively, in the engaged position.
  • an opening 18 is formed in the closing wall 8, under which the fingers can be slipped to pull the cover D loose from the holder E.
  • Figs. 10-13 show a number of alternative designs of the engagement lip 9 in the same position and elevational view as represented in Fig. 8.
  • Fig. 14 shows the cross section along line XIV- XIV of Fig. 13. It clearly shows that in that exemplary embodiment the engagement lip 9 is held in the engagement position by way of a breakable connecting bar 19.
  • the closing wall 8 is provided with a weakening provision 10-12, at least on either side of the engagement lip 9.
  • This weakening provision 10-12 is clearly visibly represented in the various exemplary embodiments of Figs. 15-18 and designated there by the reference numerals 10, 11, and 12, respectively.
  • the weakening provisions 10-12 are provided in such a way that when the engagement lip 9 is engaged and, for opening the cover D, is pulled sideways or upwards, at least a closing wall portion 8b of the remaining closing wall 8 that is bounded by the weakening provisions 10-12 is pulled loose, and remains connected with the cover D only through a side remote from the downward edge 8a, such that the closing wall portion 8b pulled loose is engageable for the further opening of the cover D.
  • the opening 18, mentioned earlier is created, which is indicated in Figs. 4 and 9 and under which the user can slip his fingers for further opening the cover D.
  • a flange 14, extending substantially parallel to the cover wall 7 is connected with the downward edge 8a of the closing wall 8.
  • the weakening provisions 10-12 then extend also into this flange 14 on opposite sides of the engagement Up 9.
  • the weakening provisions in the flange 14 are designed as recesses
  • the weakening provisions in the closing wall 8 are designed as a thin-walled film.
  • the thin-walled film is represented in perspective and partly in cross section. As the engagement lip 9 is pulled sideways and upwards, this film is broken, which makes it visible that at least an attempt has been made to take the cover D off the holder E.
  • Fig. 17 too it is clearly visible that the flange 14 is interrupted at the weakening provision 11 and that the closing wall 8 is of thin-walled design at the weakening provision 11.
  • the weakening provisions 12 in the closing wall 8 are designed as recesses, and in the flange 14 connecting to the closing wall 8 are designed as films 12a.

  • a weakened line 15 may be provided in the closing wall 8, which weakened line 15 is represented in cross section in Fig. 5, and which extends between the weakening provisions 10-12 substantially parallel to the downward edge 8a of the closing wall 8.
  • this weakened line 15 is likewise designed as a thin-walled film in the closing wall 8.
  • other embodiments are possible, such as, for instance, perforations or the like.
  • the weakened line 15 can be made so weak that upon pulling the cover lip 9 the closing wall portion 8b which is bounded by the weakened line 15 and the two weakening provisions 10-12 provided in the closing wall on either side of the cover lip 9, are completely pulled loose from the closing wall 8 for forming a recess 18 in the closing wall 8.
  • the recess 18 in the closing wall 8 has a shape such that engagement of the edge bounding this recess 18 for the purpose of opening the cover D is possible.
  • the closing wall part 8b remains connected via the weakened line 15 with the rest of the closing wall 8 and therefore is pulled loose only partly from the closing wall 8.
  • the cover D is further provided with a connecting wall 17 which extends between a circumferential edge 16 of the cover wall 7 and the closing wall 8 in an upward direction with respect to the cover wall 7, while the upper edge 17a of the connecting wall 17 is connected with an upper edge 8c of the closing wall 8, such that the upper edge 3 of the casing wall 2, in a condition of the cover D when placed on the holder E, is confined between the connecting wall 17 and the closing wall 8. In that way, an airtight closure between the cover D and the holder E can be accomplished.
  • Figs. 19 and 20 show two embodiments of a cover edge adjacent the engagement position with an alternative solution for a sealing.
  • a sealing bridge 20 is provided adjacent the engagement position.
  • the sealing bridge 20 is connected with the closing wall 8 and optionally with the engagement lip 9, such that upon engagement of the engagement lip 9 at least one of the connections of the sealing bridge 20 with the closing wall 8 or with the engagement lip 9 is broken.
  • the sealing bridge 20 extends on the side of the engagement Up 9 remote from the closing wall 8.
  • the sealing bridge 20 extends between the closing wall 8 and the engagement lip 9.
  • the sealing bridge itself is provided with weakening provisions 23 which will be broken as the engagement lip 9 is pulled up, so that the sealing bridge 20 is pulled loose from the closing wall 8 of the cover.
  • the sealing bridge 20 is connected via connections 22 with the engagement lip 9.
  • the sealing bridge 20 will be pulled up together with the engagement lip 9, and the breakable connections 23 will be broken. It is also possible, however, that the breakable connections 23 are not present and that the connections 22 are designed as breakable connections 22.
  • the sealing bridge 20 then remains connected with the closing waU 8 of the cover, but upon pulling up the engagement Up 9 the breakable connections 22 are pulled loose, so that a user can tell that it has already been attempted once to open the cover.
  • Fig. 21 clearly shows that the sealing bridge 20 can optionally be connected via breakable connections 24, 25 with the closing wall portion 8b or with the flange 14 connected with that closing wall portion 8b.
  • these connections 24, 25 can also be designed as non-breakable connections, so that upon pulling up the engagement lip 9 the sealing bridge 20 is pulled loose from the closing wall 8 by breaking the weakening provisions 23 in the sealing bridge 20.
  • the holder E may be fitted with a handle, which may or may not be made of plastic, for forming a bucket. When the holder E is not provided with a handle, it is commonly designated in practice by the term 'pot'.
  • Figs. 22-27 show an exemplary embodiment of a cover intended to be placed on a can.
  • the can has an upper edge 33.
  • the upper edge 33 forms part of a wall part 35 which extends substantially parallel to the casing wall 32 and which is connected with the casing wall 32 of the can by way of a can flange 34.
  • the cover D engages the upper edge 33 of the can by way of the closing wall 38.
  • the downward edge 38a of the closing wall 38 of the cover is not engageable because it is disposed between the casing wall 32 and the wall part 35.
  • an engagement lip 39 is connected with the closing wall 38.
  • the engagement lip 39 is connected with a closing wall part 38b bounded by weakening provisions 40 which are to be broken when removing the cover D from the can.
  • the engagement Up 39 is accommodated in a storage condition in a chamber 41.
  • the chamber is formed by a lowered cover wall portion 37a in the cover wall 37.
  • the lowered cover wall portion 37a is connected with the cover wall 37 by way of chamber walls 42 extending substantially perpendicularly to the cover wall 37.
  • two chamber walls 42 are provided with a snap edge 43 behind which the engagement lip 39 is snapped in the storage condition.
  • the engagement lip 39 is engaged and brought from the storage condition into an upwardly swiveled position, which requires the lip to be moved out of the chamber 41 by pulling it away from under the snap edges 43.
  • the weakening provisions 40 are broken, so that the closing wall 38 is broken, the closing tension is removed and the cover D can be pulled further from the can while exerting a low force.
  • the covers are stackable with little loss of space, which is clearly represented in Figs. 26 and 27.
  • the top plan view of Fig. 22 shows the engagement lip 39 in an unfolded position, i.e., moved out of the chamber 41.
  • the engagement lip 39 is disposed in the chamber 41, under the snap edges 43.
  • the holder and the cover can consist in one part in that they are connected to each other with a hinge or a connecting part.

Abstract

La présente invention concerne, d'une part un couvercle, et d'autre part un ensemble fait d'un support et d'un couvercle. Ce couvercle comporte une cloison de fermeture pourvue d'un bord tourné vers le bas. La façon dont ce bord s'applique contre une collerette du support se présentant perpendiculairement à la paroi d'enveloppe du support, ou la façon dont il est protégé par une partie de la paroi qui est reliée à la collerette du support et qui se présente sensiblement parallèlement à la paroi d'enveloppe, suffisent pour que le contact de ce bord tourné vers le bas ne soit pas possible. De plus, en position de contact, le couvercle à contact est relié au bord tourné vers le bas de la cloison de fermeture, lequel couvercle à contact prend naissance sur le bord tourné vers le bas, de façon à permettre le contact.
