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. For this purpose, a compressive force must be exerted on the mixing element. A user grasps for this purpose the housing which contains the mixing element and presses it in the direction of the storage areas.
  • an opening mandrel is attached to a connection between the Produce storage areas and the mixing element by cutting through a partition, which allows the discharge of the components.
  • the mixing element is displaced by means of a plunger relative to the housing.
  • the user of the device must hold the housing of the mixing element with one hand and attach the plunger at the outlet end of the mixing element to exert a compressive force on the mixing element in the direction of the storage areas.
  • This solution entails that the housing of the mixing element is dimensionally stable and withstands the pressure forces required to hold 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 ram is accordingly small for a single use device, so it requires some skill and power 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.
  • This opposite arrangement is particularly advantageous because the fillers from both supply areas can 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 first storage area is separated from the second storage area by a release film such that the first storage area extends on a first side of the release film and the second storage area extends on a second side of the release 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 open into a common mixing channel.
  • the mixing channel contains a mixing element which is surrounded by a wrapping film.
  • the wrapping film thus forms the wall of the mixing element.
  • the mixing element may in particular be designed as a static mixing element.
  • the mixing element comprises a protuberance on which at least one of the first and second film rests.
  • the opening of the storage areas for the discharge of the two components is effected by a simple buckling movement. Due to the bending movement, a separating element arranged on the mixing element cuts through the separating film, which closes at least one of the storage areas.
  • a separating element arranged on the mixing element cuts through the separating film, which closes at least one of the storage areas.
  • the cover film comprises a first film and a second film, so that the mixing element is held between the first and second film.
  • first film serves to receive the first storage area and to receive the first outlet channel and one half of the mixing channel.
  • the second film serves to accommodate the second storage area and for receiving the second outlet channel and the other half of the mixing channel.
  • the first and second foils thereby form the walls of the corresponding storage areas as well as a part of the walls of the corresponding exit ducts.
  • the wall of the mixing element is formed by the first and second foils.
  • the first film is located on an outer side of the mixing element on the second film along a support area, wherein the first film is connected to the second film in the support area.
  • the jacket is formed by a tube.
  • the support area is advantageously flat, which allows the positioning of a tool for welding or sealing the two films along the support area in a simple manner.
  • the first exit channel is received in the first foil and the second exit channel is received in the second foil.
  • the first storage area is accommodated in the first film and the second storage area is accommodated in the second film.

  • a wrapping film can be loaded with a tool which has the recesses corresponding to the storage areas, the outlet channels and the mixing channel.
  • the wrapping film is inserted into the recesses or injected in liquid form into the recesses in such a way that it forms a thin layer which rests against the walls of the corresponding recesses.
  • the recesses of the storage areas are filled with the appropriate components, optionally closed by a release film and inserted the mixing element in the mixing channel.
  • the mixing element preferably also contains the outlet channels, so that after inserting the mixing element, the two parts of the enveloping film can be folded and connected to each other in the support areas.
  • the components as well as the mixing element with the outlet channels are already integrated in the cladding film, so that hereby the manufacture of the device is already completed.
  • the first foil and the second foil lie on one another and form a support region.
  • the first film and the second film touch and can be connected to one another at this point, so that the mixing channel is received in a fluid-tight manner in the first film and the second film or the enveloping film.
  • the connection can advantageously be made by welding.
  • a cavity remains between the mixing element and the first film and the second film or the cover film. If the mixing channel has a circular cross-section and the mixing element also has a circular cross-section, this cavity is small, but it can still happen that leaks occur when discharging the first and second components.
  • the foils or wrapping foil can of peel off the wall of the mixing element when the components exert a pressure on the inner surface of the films or wrapping film.
  • the mixing channel contains at least one protuberance, so that the corresponding film rests on the protuberance.
  • the protuberance extends on the outside of the mixing element.
  • the protuberance extends substantially over the entire length of the mixing element, so that each of the films rests along at least a large part of the length of the mixer element on the protuberance.
  • a single protuberance can be provided. If the mixing element is inserted into a first film and covered by a second film, advantageously two protuberances are provided. These protuberances are in this case preferably arranged on opposite sides of the mixing element.
  • the protuberance may be formed as a wedge-shaped body having first and second side surfaces so that the first film rests on the first side surface and the second film rests on the second side surface, and an end surface.
  • a method for manufacturing a device for storing a plurality of components intended for common consumption comprises the following steps Providing a first film and inserting the first film into a recess of a mold Inserting a mixing element in the recess Providing a second film and covering the mixing element with the second film, connecting the first film to the second film so that the mixing element is received in the first film and the second film, wherein the mixing element comprises a protuberance on which at least one of the first and second films rest.
  • the second film is inserted into a recess, wherein the recess forms the second storage area, wherein after inserting the second film in the recess of the second storage area is filled with a second component, wherein the second storage area after completion of the filling with the second component a release film is covered and the release film is so connected to the second storage area that the second component is trapped in the storage area.
  • the first storage area is filled with a first component.
  • the film with the filled and sealed second storage area is held in a mold and the mold is positioned on the first film such that the recess for the mixing channel encloses the mixing element and then the first and the second film are joined together so that the second component is enclosed in the second storage area and the mixing element is enclosed by the first film and the second film.
  • an additional separating film can be placed on the first storage area and the first component can be enclosed between the separating film and the first storage area by connecting the separating film to the first storage area in a fluid-tight manner.
  • 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, a kink being formed from the bottom end.
  • the kink point is the axis of rotation for a bending movement of the mixing element relative to the storage areas. By means of this bending movement, an opening can be made in the corresponding storage area in order to discharge the corresponding component from the storage area.
  • At least one of the outlet channels on a separating element which extends beyond the kink in the direction of the corresponding outlet channel associated with the storage area.
  • 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 storage area associated with the discharge 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 by the bending 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 may for this purpose in particular have a cutting edge facing the cutting edge.
  • the cutting edge is in particular configured such that after contacting the cutting edge with the release film by applying a low compressive force, a slot-shaped opening in the release film can be introduced.
  • 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.
  • 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 exit channel prevents one of the first or second foils closing the exit channel from resting on the floor.
  • 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 the first or second film, which must not be injured during storage of the device. Since the storage areas are surrounded by the same first or second film forming 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. If this wrapping film reaches an edge, it is severed, as is desirable when the separating element is in contact with the separating film between the storage areas, but in no case is it desirable in the case of the wrapping film, since the corresponding component can escape through the resulting leak.
  • the first holding element can move relative to the second holding element along a direction of rotation opposite to the first direction of rotation, so that a rotational movement of the first and second storage area around the kink occurs in such a way that the separating film opens the separating element comes to rest and the release film is severed by means of the separating element.
