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.
  • the invention contemplates a cover of the type described in the preamble, intended for a holder, whereby taking the cover off the holder does not require breaking away any parts of the holder, so that the holder retains its original stiffness while yet a sealing can be provided, and whereby the sealing is provided in a clearly recognizable manner, so that it is immediately clear to the user where the sealing is situated.
  • 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, while the material from which the cover is manufactured is a different material than the material from which at least the engagement lip is manufactured, so that at least the engagement lip has a different appearance than the rest of the cover.
  • 'Different material' should be understood to include the same material having a different color.
  • 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. Due to the engagement lip being manufactured from a different material than the other parts of the cover, this engagement lip can be made clearly recognizable, for instance in that it has a different color.
  • the cover lip could be designed to be, for instance, red, while the rest of the cover is blue. The user's attention is then immediately attracted by the engagement lip which stands out clearly from the rest of the cover.
  • the closing wall at least on either side of the engagement lip, is provided with a weakening provision, while the design and positioning of the engagement lip impose, upon engagement of the engagement lip for opening the cover, a pulling direction which is such that at least a closing wall portion bounded by the weakening provisions is partly or wholly pulled loose from the remaining closing wall by breaking the weakening provisions.
  • the weakening provisions mentioned will be broken, which breakage becomes 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 of 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 boundary of the two kinds of material lies adjacent the weakening provision mentioned.
  • 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 then 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.
  • Figs. 4, 5, 14 are plastic buckets.
  • the holder shown in part in Fig. 25 is a can.
  • All covers D shown in the exemplary embodiments are manufactured by means of an injection molding process 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 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 portion 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.
  • the material from which the cover D is manufactured is a different material than the material from which at least the engagement lip 9 is manufactured, so that at least the engagement lip 9 has a different appearance than the rest of the cover.
  • engagement occurs by the fingers, but 'engageable' is to be understood to include engageable with a tool, such as pliers or a screwdriver.
  • this engagement lip 9 is indicated in dots.
  • Fig. 3 shows the engagement lip 9 in the original position and in an engaged position designated 9a.
  • Fig. 4 the cover D is represented while placed on the holder E, with the engagement lip 9 in the engaged position.
  • Figs. 6 and 7 show the engagement lip 9 represented in Figs. 1-5 once again in top plan view and in side elevation in the as yet unengaged position.
  • 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 that is bounded by the weakening provisions 10-12 is pulled loose from the remaining closing wall 8, 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.
  • the boundary between the two material areas lies adjacent the weakening provisions 10, 11, 12, so that in addition to the engagement lip 9 also the closing wall portion 8b bounded by the weakening provisions has a different appearance, such as, for instance, a different color, than the rest of 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 lip 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. It will be clear that other types of weakening provisions are also possible, such as perforations, breakable connecting elements and the like.
  • 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 portion 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.
  • a boundary between the two material areas is also located adjacent the weakening line 15 mentioned, such that in addition to the engagement lip 9 also the closing wall portion 8b which is bounded by the weakened line 15 mentioned has a different appearance, such as, for instance, a different color, than the rest of the cover.
  • 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 lip 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 wall 8 of the cover, but upon pulling up the engagement lip 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.
  • a handle which may or may not be made of plastic, for forming a bucket.
  • 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 portion 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 portion 35.
  • an engagement lip 39 is connected with the closing wall 38.
  • the engagement lip 39 is connected with a closing wall portion 38b bounded by weakening provisions 40 which are to be broken when removing the cover D from the can.
  • the engagement lip 39 is designed in a different material than the rest of the cover, so that this engagement lip 39, for instance, has a different color.
  • the engagement lip 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.
  • the lowered cover wall portion 37a can be designed in a different material than the rest of the cover wall 37, so that that portion too can have a different color.
  • 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.
  • 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 injection mold for the purpose of manufacturing the cover according to the invention preferably has two plastic supply channels.
  • One plastic supply channel terminates in a first cavity in which the cover D, with the exception of the engagement lip 9, 39 and optionally the closing wall portion 8b or the lowered cover wall portion 37a, is molded.
  • the second plastic supply channel terminates in a second cavity in which the engagement lip 9, 39 and optionally the closing wall portion 8b or the lowered cover wall portion 37a is molded.
  • the first and the second cavities can be temporarily separated from each other during the molding process by means of a movable barrier in the mold. After filling one of the cavities and after some degree of curing of the plastic therein, the barrier can thereupon be pulled away and the other cavity can be filled with the other plastic material. The second plastic material will then still adhere to the first plastic material injected earlier.
  • the two cavities are connected with each other by very narrow channels in which the weakening provisions 10-12, 15 and 40 are molded.
  • the supply of the plastic should then be controlled such that the two plastics meet in the respective narrow channels which connect the two cavities with each other. In the latter case, it is possible that the two cavities are filled simultaneously with plastic.
  • the two plastic supply channels are each connected to their own respective plastic supply source, which plastic supply sources contain different plastics, for instance plastics that have mutually different colors.
