Definitions

  • the application relates to a rotary closure for closing a container having at least one opening, comprising: a cap; an insert disposed in the cap, the insert having at least one closure member disposed offset relative to the central axis of the cap for closing the mouth of the container.
  • the application relates to a combination comprising a container with at least one opening, and such a rotary closure.
  • Multi-component cartridges have long been used for storage or in the processing of multi-component materials, e.g. Two-component adhesives, used.
  • Multi-component cartridges have several, usually two chambers or receiving spaces. In these different substances are stored separately. Shortly before processing, the materials are mixed to produce the two-component material through the mixing process. This is then processed directly, whereby a reaction of the components can take place.
  • the components are discharged by means of a respective piston from the receiving spaces.
  • the volumes are discharged in the desired mixing ratio.
  • a static mixer can be connected to the mouth of the container.
  • coaxial cartridges With regard to two-component or multi-component cartridges, different designs are known.
  • coaxial cartridges the receiving spaces are arranged coaxially to each other, in so-called “side-by-side” cartridges, the receiving spaces are arranged side by side.
  • the choice of the appropriate cartridge shape depends on Purpose and the substances or components to be absorbed.
  • Coaxial cartridges offer the advantage of high stability and compactness and the possibility of storing components whose volumes differ greatly due to the mixing ratio.
  • the construction of the mouth region of the container can thus be relatively complex.
  • caps In order to keep the materials separate during storage and to safely (re-) close the cartridge, caps must be used that are adapted to the complex structure of the mouth region.
  • the mouth region may possibly have multiple openings for each component.
  • it when closing or re-closing the container, it must be ensured that the openings for one component are securely closed in relation to the openings of the other component in order to prevent a mixture of the components in the mouth region during storage.
  • the reuse of the closures is problematic because the components may mix during this process.
  • a rotary closure according to the invention for closing a container with at least one opening comprises: a cap; an insert disposed in the cap; wherein the insert has at least one closure element arranged offset relative to the central axis of the cap for closing the opening of the container; and an alignment member for aligning the closure member relative to the at least one opening during closure of the container.
  • a proper orientation is achieved by rotation of the insert relative to the container mouth to a position in which the closure member and the opening can sealingly cooperate, as long as they are moved axially (relative) to each other. Subsequently, the (relative) radial position is held while the cap continues to rotate. The rotation creates the axial movement.
  • the cap and / or the insert are in particular made of plastic.
  • the insert is in particular made in one piece.
  • the cap can be one or more parts.
  • the container preferably a multi-component cartridge, in particular a coaxial or side-by-side cartridge, is also usually made of plastic.
  • the container has openings which are arranged at the mouth region in a decentralized manner, that is offset relative to the axis of rotation of the rotary closure.
  • a plurality of tubular channels may be provided in the mouth region from a storage space of the multi-component cartridge (eg, a central storage space of a coaxial cartridge) through which the stored first component passes before being deployed via orifices.
  • the tubular channels may be surrounded by a cylindrical mouth wall. Through a channel formed within the cylindrical mouth wall, between the tubular channels, the second component may pass before being discharged over one or more openings.
  • material strands of the first component and of the second component are mixed.
  • the insert has closure elements which are associated with the respective openings. To ensure that when closing the Closure elements with the openings sealingly cooperate, the closure elements must be aligned with the openings.
  • the arranged on the cap insert with the closure elements initially rotates together with the cap. However, once a desired orientation of the closure elements to the openings is achieved, the rotation with respect to the openings is stopped.
  • An alignment member is provided for this purpose which stops the movement of the insert rotating relative to the container mouth while the cap is being rotated further to be secured to the container, e.g. B. by screwing the cap to the container.
  • the insert and the cap are connected so as to rotate together, for example, due to friction between the bearing elements of the insert and the cap, or due to an engagement or entrainment, as long as this joint rotation is not prevented by external force.
  • a disturbance of the rotational movement can take place, for example, by an engagement or a stop of the alignment element relative to the container mouth.
  • the alignment member stops the rotation of the insert at the precise moment when the closure elements are aligned relative to the corresponding openings of the container.
  • the alignment member may be an adjustment member that aligns the closure members relative to the respective openings such that the closure members and the respective associated openings align with each other before sealingly contacting the mouth of the opening or engaging the closure member into the opening ,
  • the closure operation is thus composed of a first phase and a second phase, wherein the first phase comprises the initial screwing of the cap on the container mouth.
  • the insert rotates along with the cap.
  • the cap is further screwed onto the container mouth, whereby the alignment element cooperates with the container mouth, so that the rotational movement of the insert is stopped relative to the container mouth and the sealing or engagement of the closure elements with the openings or in the openings.
  • the sealing or engagement process is achieved by an axial movement of the insert, which is generated for example by screwing the cap.
  • the second phase can be initiated after a certain pitch of the cap.
  • a simple closure of the container is made possible, wherein the alignment of the closure elements relative to the openings by the alignment element is accomplished automatically without manual adjustment.
  • a mixing of the components when resealing the container is reliably prevented, whereby the components can be sealed separately from each other.
  • the cap has a thread for attaching the cap to a corresponding mating thread of the container by rotating the cap in a closing direction.
  • the screw cap is in this case a screw cap.
  • the cap preferably has an internal thread which is screwed onto an external thread of the container mouth. The closure elements move by screwing the cap to the container openings and possibly in this.
  • the insert is rotatably connected to the cap via a bearing.
  • the alignment element cooperates with the container mouth and holds the aligned closure elements in their intended position relative to the openings.
  • the bearing has a resistance to free rotation of the insert relative to the cap.
  • the resistance is designed so that under real conditions, ie in normal rotational movements without external action, the insert rotates with the cap.
  • the resistance is designed so that when a predetermined torque between the cap and the insert is exceeded, a rotation of the cap relative to the insert is made possible.
  • the cap after the alignment member cooperates with the bottle mouth, the cap must be further rotated at a certain minimum torque to overcome the resistance exerted by the blocking alignment member, insert, and bearing and to fully unscrew the cap onto the container mouth.
  • the resistance can be generated for example by friction.
  • the bearing may comprise a pin which extends from the end face of the cap into the interior of the cap.
  • the insert can be a corresponding bearing element having a bore, so that the insert can be attached to the pin. Due to the design of the bearing, the resistance can be adjusted.
  • the insert is preferably fixed axially relative to the cap, so that it is fixed in the axial direction tensile strength on the cap. This prevents that when removing the closure of the insert is removed together with the cap.
  • the closure with the cap can be rotatable but axially fixed, welded.
  • the closure element may have a pin for engagement in the at least one opening.
  • the closure element preferably has a closure body with a groove for engagement of an opening wall of the container delimiting the opening.
  • the alignment element has at least one first stop, which interacts with a rotation of the cap with a second stop of the container.
  • the stops are aligned against each other so as to radially fix the closure element and the associated opening in aligned position while the cap is further rotated in the closing direction.
  • each closure element or each opening may have a stop.
  • the first stop is formed by a projection extending from the end face (eg, a base plate abutting the end wall of the cap) of the insert toward the container opening.
  • the projection thus extends into the interior of the cap.
  • the projection may comprise a curved portion, for example in the form of a portion of a cylinder jacket surface.
  • the cylindrical surface is, seen in the direction of closing, after open at the front, at least partially closed at the back.
  • the section can snugly engage behind a tubular channel in the mouth region and fix the insert in this position radially relative to the opening, while the cap is rotated further in the closing direction of rotation.
  • the alignment member may be configured for alignment of the closure member relative to the opening during closure of the container. Escape is in the context of this application a synonym for an orientation such that the alignment element and the associated opening -see in the axial direction-overlap or are arranged so congruent that they by an axial displacement of the insert relative to the container mouth in sealing contact or can be brought into mutual engagement.
  • the alignment element is in particular designed such that the closure element aligns itself relative to the opening during the closing of the container.
  • the insert is designed to be self-aligning or self-aligning relative to the cap.
  • the object is also achieved by a combination comprising: a container having at least one opening; and a rotary closure as described above for closing the at least one opening.
  • a container having at least one opening ; and a rotary closure as described above for closing the at least one opening.
  • Other properties of the container have already been described above or will become apparent from the further description and the drawings.
  • the invention is suitable for use with all conceivable two- or multi-component cartridges, for example coaxial cartridges, side-by-side cartridges, etc.
  • the container has at least one cylindrical mouth portion, which has a thread for attaching the rotary closure.
  • the cylindrical mouth portion encloses all of the openings of the container.
  • the container also preferably has a second stop. This cooperates with the first stop as described above to prevent in a certain relative radial position rotation of the insert relative to the mouth region of the container.
  • the container has, in particular, at least one outlet wall, the end of which delimits the at least one opening, wherein the end section of the outlet wall is designed as a second stop for cooperation with the first stop of the rotary closure.
  • a plurality of tubular channels may be provided in the mouth region, which are delimited by the mouth wall, and through which the stored first component passes before it is discharged through the openings.
  • the container is designed as a coaxial cartridge.
  • FIG. 1 shows the mouth region of a coaxial cartridge 1 according to the present invention.
  • the coaxial cartridge 1 has a cylindrical container wall 10 and an end wall 11. Within the container (not shown) are provided two coaxially arranged, separated by an intermediate wall storage container.

  • the tubular channels are delimited by cylindrical mouth walls 151, 152, 153, the ends of which enclose the openings 161, 162 and 163, respectively define.
  • a material strand of the first material component can be dispensed from the inner storage container of the coaxial cartridge 1 via one of the openings 161, 162 or 163 via the three (3) channels.
  • the ends of the mouth walls 151, 152, 153 protrude beyond the end of the cylindrical outer wall 13.
  • the area that lies within the cylindrical wall portion 13 between the tubular channels is connected to the outer storage container of the coaxial cartridge 1.
  • the second material component from the outer storage container thus exits through the area between the channels and over the opening 17 which is delimited by the (inner) end of the wall portion 13 and the (outer) ends of the mouth walls 151, 152, 153.
  • the strands of material from the inner and outer residence containers are thus arranged adjacent to one another at the exit.
  • the screw cap has two components, namely a cap 2 and an insert 3 (inlay).
  • the cap 2 consists essentially of a cylindrical shell wall 20 and an end wall 21. Within the cylindrical shell wall 20, an internal thread 22 is formed, so that the cap 2 on the external thread 14 of the container 1 from the FIG. 1 can be screwed. On the outside of the cylindrical jacket wall 20 ribs 23 are formed to improve the handling of the cap 2.
