Definitions

  • the invention relates to a canister with a closure securing member.
  • canisters can, for example, be produced from metal and/or plastics material and comprise a container which delimits a receiving space for a filling material.
  • the container comprises a removal opening which can be closed again by a cover of the canister.
  • a canister the cover of which comprises an annular insert having an inner thread for fixing to the container, is known from the patent U.S. Pat. No. 10,232,990 B2.
  • the exterior of the canister may be produced from metal or plastics material.
  • the annular insert is rotatable about the screw axis of the inner thread on the cover base and is supported in a displaceable manner in the direction of the screw axis.
  • the annular insert and an additional ring which is rigidly connected to the cover base comprise mutually opposite teeth.
  • the tooth rings are decoupled from each other by resilient force. In order to open the cover, the tooth rings are connected or engaged with each other by applying a pressing force to the cover base in the direction of the screw axis. By pulling at the same time, the screw closure can be released and the cover can be separated from the container.
  • the cover is retained in a closed position on the container only by the frictional engagement of the screw thread.
  • the screw closure can, for example, become loose as a result of powerful shaking or vibrations. Since the cover base or the outer shell of the cover and the thread insert are connected to each other only loosely or can be rotated and displaced relative to each other, the striking of the cover base on the thread insert can further promote loosening of the screw connection.
  • the components of the cover which are loosely connected to each other can cause rattling noises when the canister is moved.
  • Such loosely supported cover shells may convey the impression of instability. Since the outer shell of the cover in the closed position of the cover does not have any clearly defined position, portions of inscriptions or other printed matter on the container and on the cover are also not in a defined orientation relative to each other.
  • An object of the present invention is therefore to provide a canister with a closure securing member which effectively retains the canister cover in the closed position counter to unintentional opening.
  • the canister comprises a container having a removal opening and a cover for closing the removal opening.
  • the container and the cover each comprise a closure connection which are adapted to each other, for example, threaded ribs of a screw closure, protruding and recessed structures of a bayonet closure or edge portions which overlap each other in the closed position and which are thereby connected to each other in a non-positive-locking manner.
  • the container and the cover each comprise a wall and an insert, on which the respective closure connection is arranged.
  • the cover In order to close the canister, the cover is moved into a closed position relative to the container in accordance with the respective closure connection.
  • the container insert and the cover insert comprise securing elements which are adapted to each other and with which the cover can be secured to the container in the closed position.
  • At least one of the securing elements is arranged on a resiliently deformable portion of the cover insert or the container insert.
  • the securing elements comprise contact faces which move into abutment with each other when the cover is closed. At least one of these contact faces is inclined relative to the closure direction so that the securing element is urged out of the rest position thereof at the resiliently deformable portion when the cover is closed so that the cover can be moved into the closed position. At the latest when the closed position is reached, the securing elements lock in a positive-locking manner with respect to the respective movement direction.
  • the resiliently deformable portion(s) of the cover and/or container insert can also be deformed by an external force action. The respective securing elements are thereby urged out of the rest position or blocking position thereof into a release position and the closure can be opened.
  • the container wall is at least partially produced from metal.
  • the container wall can be produced, in particular integrally, from a deep-drawn and/or otherwise shaped metal sheet.
  • the container wall or portions thereof can be produced from one or more materials, such as, for example, plastics materials, metals or wood materials.

  • FIG. 1 shows a closed canister 1 , wherein a cover 5 is connected to a container 3 in a closed position and a removal opening 30 of the container 3 is preferably tightly closed in this instance.
  • FIG. 2 shows the container 3 and the cover 5 with the canister 1 open as a perspective view, wherein the inner side of the container 3 and the cover 5 can be seen.
  • FIG. 3 shows a bottom view of the cover 5 .
  • the container 3 comprises a container wall 31 which is preferably produced from a deep-drawn metal sheet and a container insert 33 which is connected to this container wall 31 .
  • the mutual freedom of movement of the container wall 31 and the container insert 33 can be limited, for example, by projecting and/or recessed structures which undercut each other with respect to one or more movement directions and/or by the geometric shape of these portions.
  • the freedom of movement can be limited to such an extent that the portions are connected to each other at least approximately non-movably with respect to translational movements in the direction of a container axis A and/or with respect to movements orthogonal to the container axis A, such as, for example, rotational movements about the container axis A.
  • the freedom of movement of the cover insert 53 which is connected to the cover wall 51 is also limited relative to the cover wall 51 .
  • the container wall 31 and/or cover wall 51 of which are produced from sheet metal, for example, inwardly formed beaded rims 39 , 59 can be used as stop elements for structures which project radially outwardly on the container insert 33 or on the cover insert 53 , such as, for example, rib portions 41 , 61 ( FIG. 4 ).
  • these rib portions 41 , 61 have a wedge-like cross-section.
  • the beaded rim 59 is resiliently deformed outward by the slightly inclined faces of the rib portions 61 with respect to the cover axis B and subsequently jumps back into the rest position thereof again as soon as the cover insert 53 and therefore also the rib portions 61 reach the end position thereof behind the beaded rim 59 .
  • the cover insert 53 is thereby connected to the cover wall 51 in a positive-locking manner with respect to translational movements in the direction of the cover axis B.
  • the retention force of this connection can be fixed by the shape of the beaded rim 59 and/or by the shape and the radial projection of the rib portions 61 .
  • a high retention force can be brought about, for example, in that the beaded rim 59 or at least a portion of the beaded rim 59 is bent over only to such an extent that abutment faces of one or more rib portions 61 directly abut the edge of the bent-over cover wall 51 and/or in that the abutment faces of the rib portions 61 are orientated at least approximately orthogonally relative to the cover axis B.
  • the retention force may be so large that a non-destructive separation of the portions is impossible.
  • the necessary pulling force for separating the portions is so large in this case that the beaded rim 59 or the rib portions 61 are plastically deformed.
  • Cover walls 51 in which the metal sheet is formed by, for example, 270° or more, at the beaded rim 59 , can, however, be separated from the cover insert 53 again comparatively easily by resiliently deforming the beaded rim 59 again.
  • the cover wall 51 and the cover insert 53 comprise annular or generally frame-like edges 52 , 54 which overlap and abut each other in the connected state.
  • the freedom for relative movements of the two portions in one plane orthogonal to the cover axis B is thereby limited.
  • circular edges 52 , 54 only rotations about the cover axis B are possible.
  • the rib portions 61 are arranged so as to be distributed along the edge 54 and project radially at this edge 54 .
  • the outer side of the edge 54 comprises at least at one location, for example, at four locations between two adjacent rib portions 61 , a radial recess or indentation 63 .
  • the edge 52 of the cover wall 51 comprises at the corresponding locations of the inner side projections 64 which project radially inwardly. In the case of cover walls 51 comprising sheet metal, these projections 64 may be, for example, regions of the beaded rim 59 which project radially inwardly locally further than the adjoining regions. If the cover insert 53 is connected to the cover wall 51 , the projections 64 are in engagement with the recesses 63 . As a result of this positive-locking connection of structures at the edges 52 , 54 , the cover insert 53 and the cover wall 51 are connected to each other in a rotationally secure manner.
  • the container insert 33 can be connected to the container wall 31 in a similar manner to the connection of the cover insert 53 to the cover wall 51 .

  • the rib portions 41 which project in the lower region at the edge 34 of the container insert 33 form together with the inwardly projecting beaded rim 39 of the container wall 31 a positive-locking connection of these portions with respect to translational movements in the direction of the container axis A.
  • the recesses 43 at the edge 34 of the container insert 33 and the projections 44 at the edge 32 or at the beaded rim 39 of the container wall 31 bring about a positive-locking, rotationally secure connection of the container insert 33 to the container wall 31 .
  • the container insert 33 comprises a first closure connection 35 and the cover insert 53 comprises a second closure connection 55 which cooperates therewith.
  • the first closure connection 35 is a threaded rib of an outer thread which is formed in the upper region at the outer side of the edge 34 and the second closure connection 55 is a threaded rib of an inner thread which is formed in the upper region at the inner side of the edge 54 .

  • the primary securing element 37 and/or the secondary securing element 57 comprise(s) a contact face 35 , 56 which is chamfered with respect to the direction of the closing movement.
  • the secondary securing element 57 springs, as a result of the resilient restoring force thereof, into a blocking position in which stop faces 38 , 58 of the securing elements 37 , 57 which are preferably arranged approximately orthogonally to the direction of the closing movement are opposite each other and secure the cover 3 in the closed position.
  • the primary securing elements 37 could also be resiliently deformable or be arranged on resiliently deformable portions of the container insert 33 .
  • the cover insert 53 comprises two diametrically opposed secondary securing elements 57 which project at the inner side of the edge 54 downward or in the direction of the cover axis B.
  • cover inserts 53 could also comprise only one or more than two, for example three, secondary securing elements 57 .
  • the cover 1 with up to three secondary securing elements 57 can readily be operated with one hand.
