Definitions

  • the invention relates to a device for storing and dosing a plurality of components which are mixed together immediately prior to use and to be supplied in the mixed state of use.
  • Such devices are used for example for storage of the individual components of a multi-component adhesive.
  • Another application is found in the food industry or for the packaging of medical preparations. Common to all these devices is that the individual components are stored until they are consumed in separate storage areas that can be closed.
  • a chamber of a blister pack for a liquid or powdered filling material usually consists of a deep-forming film and a sealing film, which closes the filling material sealingly in the storage state from the environment.
  • the device according to EP1947028 A2 comprises a first storage area for receiving a first component and a second storage area for receiving a second component, wherein the two storage areas are arranged substantially one above the other.
  • Each storage area includes a bulge, which is tightly closed with a cover.
  • the cover is sealable with the bulge to form a seam and the storage areas are outside the seam connectable by a connecting element, which is in particular a welded connection.
  • the covers are made of the same material, which is designed as a film, which is designed in particular as a deep-forming film.
  • multilayer films for example aluminum composite films, in which the surface to be welded consists of a good weldable plastic.
  • the storage areas open unilaterally into a mixing area which is separated from the storage areas in such a way that each component is stored separately in the storage area provided for it, as long as it is stored.
  • dividers are arranged between the storage areas.
  • Each storage area is designed as a half-shell filled with a component, to which a groove-shaped depression adjoins, into which a mixing element can be inserted.
  • the dividers are forced apart by the exiting components at a predetermined location to open a passage to the trough-shaped depression forming the discharge channel.
  • An opening mandrel is attached to the mixer in order to establish a connection between the storage areas and the mixing element by cutting through a dividing wall, which enables the discharge of the components.
  • the mixing element is displaced by means of a plunger relative to the housing.
  • the force to be pressed apart to separate the separating webs or to sever the dividing wall on the plunger is relatively large, since the dividing webs or dividing wall must have a sufficiently large wall thickness in order to protect the filling compound from impacts and damage during transport and storage and to prevent their escape.
  • the plunger is accordingly small for a single use device, so that it requires some skill to safely open the passage to the storage areas when the components of the filling are to be mixed and discharged.
  • the device for storing a plurality of components, which are intended for common consumption.
  • the device comprises a first storage area for receiving a first component and a second storage area for receiving a second component.
  • the first storage area is arranged opposite to the second storage area. That is, the first storage area is located above or below the second storage area.
  • the first storage area is separated from the second storage area by a film, so that the first storage area extends on a first side of the film and the second storage area extends on a second side of the film.
  • the first storage area can be connected to a first outlet channel.
  • the second storage area can be connected to a second outlet channel.
  • the first outlet channel and the second outlet channel can open into a common mixing channel.
  • Between the first and second storage area and the first and second discharge channel a line-shaped kink is arranged. Under a line-shaped kink is a kink to understand, which has the shape of a line.
  • the line can be straight or curved.
  • a mixing element may be arranged to homogeneously mix the components prior to their use.
  • the mixing element may in particular be designed as a static mixing element.
  • the first storage area and the first exit channel are arranged on the first side of the film, the second storage area and the second exit channel are arranged on the second side of the film.
  • This arrangement is particularly advantageous because the fillers from both supply areas could be applied simultaneously.
  • pressure can be exerted manually on the two storage areas by being compressed with one hand.
  • the device can be clamped in a Austragoskar by means of which a pressure on the storage areas can be applied. Under this pressure, the flexible shell of the storage areas yields.
  • the volume of the storage area decreases continuously with progressing discharge until the filling material has completely left the storage areas.
  • the wall of the storage area may also comprise a wrapping film or a plurality of wrapping films.
  • At least one of the first and second exit channels may have a bottom.
  • This floor is according to a preferred embodiment in one piece with the outlet channels and may even form a unit with the adjoining the outlet channels mixing element.
  • the bottom has an end facing the corresponding storage areas, the kink being formed from the end of the floor.
  • At least one of the outlet channels has a separating element which extends beyond the kink point in the direction of the storage area associated with the corresponding outlet channel.
  • the separating element advantageously contains a recess. This recess ensures that the severed film does not block the corresponding exit channel.
  • the separating element has a first and a second arm which extends beyond the kink point in the direction of the supply region associated with the outlet channel.
  • the storage area can also have an arm which extends beyond the kink point in the direction of the corresponding outlet channel. This arm is in the event that it emanates from the outlet channel so connected to the outlet channel, that it participates in a movement of the outlet channel whose movement. This means that movement of the outlet channel causes movement of the arm. If the outlet channel is moved about the bend point relative to the storage areas by means of a rotary movement, the corresponding arm of the separating element comes into contact with the film and begins to exert a compressive force on the film. By this pressure force, the film can be weakened or scratched, so that the way for the corresponding component is released in the direction of the outlet channel.
  • the arm according to one of the preceding embodiments has for this purpose a film facing the cutting edge.
  • the cutting edge is in particular designed such that after contacting the cutting edge with the film using a low pressure force, a slot-shaped opening can be introduced into the film.
  • the cutting edge is in particular arranged at or in the vicinity of the tip of the separating element, ie at the point where the two arms come together.
  • At least one each of the first and second arms which are arranged adjacent to one another, form a tip, on which a cutting edge facing the film is arranged. If the cutting edge extends over at least part of the side of the arm facing the film and if this cutting edge in the tip runs together punctiform in particular, a particularly low compressive force is required to close the film cut as the entire compressive force can be concentrated to a point and thus a small deflection of the channel is required to cause a puncture of the film.
  • the recess is surrounded by the tip, the corresponding first and second arm, as well as the bottom of the corresponding outlet channel.
  • the exit channel includes a bottom, and a first wall and a second wall extending from the bottom.
  • the wall at the outlet channel prevents a film, which closes the outlet channel during the assembly, rests on the ground.
  • At least one of the arms can connect to the corresponding first or second wall.
  • the arm may be formed by at least one of the first and second walls.
  • Arm and walls can be part of a one-piece mixing element.
  • Such a mixing element can be produced in particular as a plastic component by injection molding.
  • the tip-opposite surface may be rounded. Such a rounding is particularly advantageous when the separating element is surrounded by a film that must not be injured during storage of the device. Since the storage areas are surrounded by a wrapping film, it is possible to wrap the discharge channels and the mixing element with this wrapping film in one operation. However, this wrapping film must be able to deform under finger pressure, so be flexible. If this wrapping film reaches an edge, it is severed, as when the separating element is in contact with the film between the layers Storage areas is desired, but in the case of the wrapping film is desired in any case, since the corresponding component can escape through the resulting leak.
  • the film can be bent along the kink, so that in the folded state, the film can be severed by the arm and / or the separating element.
  • the separating element is arranged such that the film on the first side can be severed by means of the separating element when the angle between a foil closing off the storage regions and at least one of the bottoms of the first and second outlet channels is less than 180 °.
  • the separating element can be arranged such that the film on the second side can be severed by means of the separating element if the angle between a foil closing off the supply regions and at least one of the bottoms of the first and second outlet channels is greater than 180 °.
  • the film on the side of the opposite storage area can be severed when the angle between the film on the first side of the kink, which contains the storage area and the second side of the kink, which contains the outlet channel, is greater than 180 °.
  • the mixing element can be accommodated in the film, so that the production of a tube for receiving the mixing element can be omitted.
  • the walls of the mixing element are thereby at least partially enclosed by a wrapping film.
  • the wrapping film which is arranged above the mixing element, cooperates with a wrapping film, which is arranged below the mixing element.
  • the wrapping film is respectively the same enveloping film surrounding at least one of the first or second storage areas.
  • the two enveloping films lie on each other.
  • the two enveloping films touch each other along the support regions and can be connected to one another at these contact regions, so that the mixing channel is received in a fluid-tight manner in the enveloping films.
  • the connection can advantageously be effected by welding or sealing. Alternatively or in addition to this, a seam may be provided.
  • a cavity between the mixing element and the enveloping film remains. If the mixing channel has a circular cross section, this cavity is small, but it can still happen that leaks occur when discharging the first and second components.
