Definitions
- the invention relates to a cartridge for storing at least two fluids with two fluid containers, each with an outlet, a base which is attached to the fluid container and accommodates the outlets, and a locking element which can be screwably attached to the base.
- the invention further relates to a closure plug for use on cartridges with two fluid containers and a dispensing system for fluids of a multi-component material with a cartridge with two fluid containers and an attachment, in particular a mixer and/or a closure plug.
- Such a cartridge or discharge system is generally used in conjunction with a static mixer to produce a material stream from two starting material streams.
- such cartridges contain two components of a two-component adhesive, which are introduced into a static mixer via the outlets. In the mixer, they are mixed to form a mixture that is as homogeneous as possible and emerge as a mixture at the opening.
- Static mixers are characterized by the fact that they preferably have no moving parts and the material flows to be mixed must be moved through them by means of a pump or similar.
- the document EP 2 747 899 B1 relates to a cartridge system with two containers, each of which has an outlet nozzle and a common connection area for a mixer provided with a positioning opening, and with a static Mixer with inlet nozzle and a positioning element, wherein the connection region has a ring surrounding the outlet nozzle with an internal thread, and wherein the mixer has an external thread, wherein the length of the inlet nozzle, the outlet nozzle and the positioning element as well as the position of the positioning opening are coordinated with one another in such a way that when the mixer is placed on the containers of the positioning element engages in the positioning opening and the internal thread and the external thread engage with one another before the inlet nozzle and the outlet nozzle touch.
- a first aspect of the invention relates to a cartridge for storing at least two fluids, comprising: two fluid containers, each with an outlet; a base which is arranged on the fluid containers and surrounds the outlets; and a locking element which can be mounted on the base in a captive manner; wherein the base has an external thread at least in sections, the locking element has an internal thread at least in sections and the internal thread is designed to interact with the external thread, and wherein the base has a first stop which, by interacting with a second stop of the locking element, prevents the locking element from being unscrewed from the external thread.
- a second aspect of the invention relates to a dispensing system for fluids of a multi-component material, comprising a cartridge with two fluid containers, each with an outlet; a base which is arranged on the fluid containers and surrounds the outlets; a locking element which can be mounted on the base in a captive manner; and an attachment, in particular a static mixer and/or a closure plug; wherein the locking element has an opening through which the attachment can be guided in such a way that the attachment can be attached to the cartridge when the locking element is mounted on the base, and wherein the locking element can be moved by screwing in the direction of a longitudinal axis of the base when mounted on the base in order to seal the attachment with the outlets of the base.
- a third aspect of the invention relates to a closure plug for use on double cartridges, comprising: a web that can engage in a corresponding recess on a double cartridge and thus determines an angular position when mounting the closure plug; and a securing element that can engage in a recess of a locking element and thus prevents unlocking of the locking element, wherein the securing element has a predetermined breaking point so that it can be broken off by a user for the first unlocking.
- a fourth aspect of the invention relates to a method for assembling a cartridge, comprising the following steps:
- Unscrewing in the sense of the invention is preferably turning.
- Preventing unscrewing in the sense of the invention is preferably a blocking of a rotational movement of the locking element, so that it cannot be released from the base by a rotational movement during normal use.
- the invention is based on the approach of being able to mount a locking element for locking attachments for the cartridge onto the cartridge in a captive manner.
- Attachments for the cartridge include a static mixer and a sealing plug.
- the security against loss is achieved in that a first stop of the base in the direction of a screwing movement comes into contact with a second stop of the locking element when the locking element is loosened. This prevents the locking element from being unscrewed from the external thread.
- a thread groove of the external thread at the end facing away from the fluid containers is limited by the first stop.
- the locking element can be pre-assembled on the cartridge at the factory. This results in a reduction in the number of individual parts that must be kept in stock by distributors, for example. In addition, the locking element cannot be lost if used as intended.
- the locking element can be moved in the mounted state on the base by a screwing movement in the direction of a longitudinal axis of the base in order to sealingly connect an attachment for the cartridge, in particular a mixer and/or a closure plug, to the outlets.
- the first stop is part of the external thread and/or the second stop is part of the internal thread. If a stop is formed by part of the respective thread, no separate stop needs to be provided. This makes it possible to simplify the structure of the respective element, in this case the base and the locking element. In particular, this also makes it possible to simplify the structure of the respective injection mold.
- the internal thread has a projection which is designed to interact with a recess of a thread groove of the external thread in such a way as to cause a rotational resistance when screwing the locking element.
- the rotational resistance serves in particular as haptic feedback for a user that a certain screw position has been reached.
- the rotational resistance can be arranged in such a way that the haptic feedback occurs when the locking element is in a closed state.
- the cartridge has a fastening element in an area facing the fluid containers in order to be fastened to a dispensing device, in particular a dispenser. This ensures that the cartridge is held securely in the dispensing device.
- the base of the cartridge has a recess which extends in the direction of the longitudinal axis of the base and into which a web of the attachment can engage. This can ensure precise positioning of an attachment, in particular a static mixer or a sealing plug in its longitudinal axis on the cartridge.
- the external thread defines a thread groove, which preferably extends over a sector of about 150° to 180°, more preferably of about 170°, and wherein the internal thread has a thread web, which preferably extends over a sector of over 60° to 90°, more preferably of about 80°, wherein the thread groove and the thread web are coordinated in their respective extension such that the locking element for screwing by can be rotated by approximately 90°.
- the thread groove and the thread web are coordinated in their respective extension such that the locking element for screwing by can be rotated by approximately 90°.
- the thread groove narrows at least in one place in order to clamp the internal thread. This prevents the locking element on the cartridge from wobbling, which can result in rattling.
- the threaded groove narrows at its end facing away from the fluid container. This can prevent the locking element from wobbling when the locking element is in an unlocking position in which an attachment can be attached or removed.
- the base has a third stop which, by interacting with a fourth stop of the locking element, limits a closing rotation of the locking element.
- the third stop is part of the external thread and/or the fourth stop is part of the internal thread.
- the thread groove is preferably limited at its end facing the fluid container by the third stop.
- the locking element is designed as a screw cap, which has a screw ring that is closed off by a front side, wherein the front side has an opening through which the attachment can be guided.
- the locking element has a recess, in particular in the screw ring, which can interact with a securing element of the attachment, preferably in the edge of the screw ring facing the fluid containers.
- the internal thread has two thread sections which are arranged opposite one another in relation to a longitudinal axis of the locking element, wherein teeth of two thread sections of the external thread facing away from the fluid containers have a reduced tooth height in such a way that the internal thread can be pushed over them. This allows the locking element to be pre-assembled on the base of the cartridge.
- the closure plug has: a web that can engage in a corresponding recess on the cartridge and thus determines an angular position when mounting the closure plug; and/or a securing element that can engage in a recess of a locking element and thus prevents unlocking of the locking element, wherein the securing element has a predetermined breaking point so that it can be removed, in particular broken off, by a user for unlocking.
- the safety element prevents the locking element from being unlocked accidentally. It also ensures that it can be recognized whether a cartridge has already been opened or not.
- the arrangement of the safety element on the closure plug means that the cartridge can be reused without being damaged.
- the safety element could also be arranged directly on the cartridge, but would then have to be broken off.
- the securing element is arranged on the web.
- a particularly favorable positioning of the securing element in relation to the locking element can be achieved.
- this positioning is on the edge of the locking element facing the fluid containers.
- the closure plug has two pins which are designed to engage in outlets of the cartridge in such a way that a dead volume in the outlets is reduced, in particular prevented. This can prevent or reduce an air inclusion when filling the cartridge. This increases the quality of the filling. On the other hand, an air inclusion when resealing the cartridge, for example during an interruption in use by the user, can be reduced or avoided.
- the pins are conical, tapering from the main body of the closure plug towards their free end.
- the outlets of the cartridge are also conical, in particular in such a way that they taper towards the fluid container.
- the conicity of the pins and/or the outlets is 1%.
