Definitions

  • the invention relates to a packaging system for separately storing at least two flowable components which in use are to flow jointly from the packaging system, the packaging system comprising at least two product chambers closable with respect to each other and an outlet opening, the packaging system being able to assume at least one storage condition and one mixing condition, while, in the storage condition, each product chamber being closed with respect to the other product chamber and while, in the mixing condition, at least one of the product chambers is provided with a fluid connection with at least one of the other product chambers, while the packaging system is provided with at least one dividing wall located between the at least two product chambers, which dividing wall is provided with an openable closing element for bringing about the fluid connection, while the packaging system is further provided with driving means for providing, in at least one of the product chambers, a first predetermined pressure which is sufficiently high to bring the closing element into an opened condition.
  • Such a packaging system is, for instance, known from US patent specification US 4,693,706 .
  • the known system is provided with two product chambers divided by a membrane.
  • the known system is further provided with a plunger to generate, by means of hand power, a pressure in the first product chamber which is sufficiently high to make the membrane rupture or separate. After this, the two products can mix and be dispensed to an outlet opening.
  • This known system has the drawback that opening the membrane can take place in an uncontrolled manner.
  • Such a packaging system is also known from US patent specification US 5,082,146 .
  • the known system is provided with a container inside which two compartments are divided by a membrane. Both compartments have been filled with a product and a gas under a pressure. By letting gas escape from the container via a valve in the first compartment, the membrane will rupture or separate under the influence of a pressure difference between the compartments created by this, so that the two products can mix. Finally, the mixed product can be dispensed under the influence of the pressure of the gas present, which then serves as a propellant.
  • a drawback of this known packaging system is that the products to be vaporized are, in each of the compartments, in contact with a propellant in that compartment before use, which is not allowed for all vaporizable products.
  • the object of the invention is to provide a packaging system by means of which this need can be filled.
  • a packaging system which is characterized in that the driving means are provided with a pressure chamber for storing propellant with the aid of which the first predetermined pressure can be applied.
  • the propellant is, at least in the storage condition, not in contact with the flowable components in the product chambers.
  • the use of the propellant makes it possible to generate the first predetermined pressure in a controlled manner, for instance by means of a pressure regulating device or reducing valve, which pressure is sufficiently high to bring the closing element into an opened condition.
  • a special embodiment of a packaging system is characterized in that the fluid connection at least extends from at least one product chamber of a first type through at least one product chamber of a second type to the outlet opening, the product chamber of the first type and the product chamber of the second type each being one product chamber of the at least two product chambers.
  • the fluid connection at least extends from at least one product chamber of a first type through at least one product chamber of a second type to the outlet opening, the product chamber of the first type and the product chamber of the second type each being one product chamber of the at least two product chambers.
  • the driving means are also arranged for applying, in the product chamber of the first type, a second predetermined pressure which is sufficiently high to drive a flowable component of a first type present in the product chamber of the first type out of the product chamber of the first type.
  • a second predetermined pressure which is sufficiently high to drive a flowable component of a first type present in the product chamber of the first type out of the product chamber of the first type.
  • the outlet opening will preferably be closable in the storage condition. This offers the advantage that the outlet opening can be provided in a wall of the product chamber of the second type.
  • outlet opening is closable in the mixing condition. This offers the advantage that a user can have the mixing take place as much as possible before the components are to flow jointly from the packaging system.
  • the volume of the product chamber of the second type is at least equal to the volume of the product chamber of the first type in the storage condition.
  • This embodiment may be very suitable when both the first and the second component comprise a gas.
  • the volume of the product chamber of the second type is at least equal to the volume of the product chamber of the first type in the storage condition plus the volume of the flowable component of the second type in the storage condition.
  • This embodiment may also be very suitable when, for instance, the first component easily mixes with the second component, such as for instance a gas and a vapor.
  • the volume of the product chamber of the second type is at least equal to the volume of the product chamber of the first type in the storage condition plus the volume of the flowable component of the second type in the storage condition plus an extra volume.
  • This embodiment may be very suitable when, for instance, the mixing of the first component with the second component takes place more effectively in a room which is slightly larger than the volume of the first component and the volume of the second component together. In other words, this embodiment is particularly suitable for fluid-like components.
  • the product chamber of the first type and the product chamber of the second type are fixedly connected with each other.
  • the system may then for instance be designed as a can or bottle.
  • the product chamber of the first type and the product chamber of the second type are detachably connected with each other.
  • the at least product chambers can be separately manufactured, stored, sold and purchased.
  • this leaves a freedom of choice for the combination of at least two components which are to be stored in the system and are to be mixed with each other during use. This may, for instance, be useful when one of the at least two flowable components comprises a color component to be freely determined. Such color components may, for instance, be applicable with paint sprays or cosmetic products.
  • the driving means may be detachably connected with at least the product chamber of the first type. In that case, it is also possible that the driving means are sellable separately from the packaging system and can, optionally, even be used multiple times.
  • the packaging system is provided with at least two product chambers of the first type which are, in the mixing condition, each provided with a fluid connection with at least one product chamber of the second type.
  • a component has been included which differs from the component included in one of the other of the at least two product chambers of the first type.
  • the at least two product chambers of the first type have mutually different volumes, which offers the advantage that it is possible to store much volume of a first component of, for instance, three components in the packaging system and, for instance, little volume of a second component of three components.
  • Fig. 1 shows a packaging system V for separately storing at least two flowable components which in use are to flow jointly from the packaging system V.
  • the packaging system V comprises at least two product chambers A, B closable with respect to each other.
  • product chamber B is a product chamber of the first type and, in this example, product chamber A is a product chamber of the second type.
  • the packaging system is further provided with an outlet opening 1.
  • a dividing wall 4 is located between the two product chambers A, B. This dividing wall 4 is provided with an openable closing element 3 for bringing about a fluid connection between the product chamber of the first type B and the product chamber of the second type A.
  • the packaging system is further provided with driving means 6 for applying, in the product chamber B, a first predetermined pressure which is sufficiently high to open the closing element 3 in the dividing wall 4, that is, to bring it into an opened condition.
  • the driving means 6 are provided with a pressure chamber C for storing propellant with the aid of which at least the first predetermined pressure can be built up.
  • the driving means 6 are further provided with a release means 9 for releasing gas from the pressure chamber C for the purpose of building up at least the first predetermined pressure in the product chamber of the first type B.
  • An example of such a release means is described in the non-prior published application NL 1021544 of the applicant.
  • the packaging system can assume at least one storage condition and one mixing condition.
  • each product chamber A, B is closed with respect to each other product chamber A, B.
  • the mixing condition at least one of the product chambers A, B is provided with a fluid connection with one of the other product chambers A, B.
  • the packaging system diagrammatically shown in Fig. 1 is in the storage condition.
  • the openable closing element 3 needs to be brought into an opening position.
  • the release means 9 is pulled in the direction of arrow P.
  • a fluid connection (not shown in detail) between the pressure chamber C and a driving position 7 is created.
  • the propellant which has been included in the pressure chamber C under a relatively high pressure will flow through the fluid connection (not shown in detail) to the driving position 7.
  • a pressure regulator not shown in detail in Fig. 1
  • the first predetermined pressure can be applied in the product chamber B.
  • a suitable device for realizing at least the first predetermined pressure with the aid of a propellant included in a pressure chamber is described in the non-prior published application NL 1021544 of the applicant.
  • a reference pressure on the basis of which the fluid connection between the pressure chamber C and the driving position 7 is regulated.
  • a passage (not shown in detail) from the pressure chamber C to the driving position is released.
  • the passage can be released, for instance with the aid of a plunger and in a gas thus enclosed in a volume.
  • the first predetermined pressure is applied by moving disk 5 in the direction of arrow D with the aid of the propellant.
  • Disk 5 closely abuts the inner walls 11 of product chamber B.
  • the volume of the product chamber B will decrease and the pressure in the product chamber B will, as a result, increase.
  • the closing element 3 will thus be pressed out of the dividing wall 4 in the direction of arrow O. In this manner, a fluid connection is created between product chamber A and product chamber B.
  • the packaging system is thus in the mixing condition.
  • the fluid connection extends from product chamber B through product chamber A to the outlet opening 1.
  • a bag or a bellows may be used which is filled by the propellant when the propellant is released from the pressure chamber C.
  • the pressure in the product chamber of the first type is increased to at least the first predetermined pressure, upon which the closing element 3 is brought into the opened condition, or even to at least the second predetermined pressure, so that the component of the first type flows to the product chamber of the second type via the opening formed by removing the closing element in the dividing wall 4.
  • the product chamber of the first type is formed by a bag or a bellows in which the component of the first type has been included.
  • the pressure is increased by a pressure of the propellant exerted on an outside of the bag or bellows.
  • a flowable component of the first type will be included and, in product chamber B, a flowable component of a second type will be included.
  • these two flowable components of the first type and of the second type can contact each other and mix with each other.
  • the volume of the second of the at least two product chambers, product chamber A is at least equal to the volume of the first of the two product chambers, product chamber B, in the storage condition. It is, however, also possible that the volume of the second of the at least two product chambers, product chamber A, is at least equal to the volume of the first of the at least two product chambers, product chamber B, in the storage condition plus the volume of the flowable components of the second type. It is further possible that the volume of the second of the at least two product chambers, product chamber A, is at least equal to the volume of the first of the at least two product chambers, product chamber B, in the storage condition plus the volume of the flowable component of the second type plus an extra volume.
  • the outlet opening 1 is closable in the storage condition. However, it is also possible for the outlet opening 1 to be closable in the mixing condition.
  • the product chamber A and the product chamber B are fixedly connected. However, it is not inconceivable that the system has a two-part design. Then, each part can comprise at least one of the two product chambers.
  • Fig. 2 shows a second embodiment of a packaging system according to the invention.
  • the packaging system V is provided with at least two product chambers of the first type B which are, in the mixing condition, each provided with a fluid connection with at least one product chamber of the second type A.
  • the disk 5 is provided with two plungers 10 which, upon a movement of the disks in the direction of arrow D, each increase the pressure in one of the product chambers B.
  • the manner in which the disk 5 is moved in the direction of arrow D with the aid of a propellant may be analogous to the manner in which this takes place in the exemplary embodiment shown in Fig. 1 .
  • each product chamber B Upon the realizing of a first predetermined pressure in each product chamber B, the closing elements 3 in the dividing wall 4 will be moved in the direction of arrow O so that a fluid connection between each product chamber B and the product chamber A is brought about.
  • a component included therein may flow to product chamber A.
  • mixing occurs of a component included in product chamber A in the storage condition with components included in the product chambers B in the storage condition.
  • the dividing wall 4 is also movable in the direction of arrow O.
  • the moving of the dividing wall 4 does not take place until the plungers 10 have each been pressed against a side of the dividing wall 4 facing the product chamber B or at least have arrived near it.
  • a result of the moving of the dividing wall 4 in the direction of the arrow O is that the components mixed with each other in product chamber A will now be driven out of the outlet opening 1 under pressure.
  • O-rings 12 may have been provided in the plunger edge. Such O-rings 12 may also have been provided in an edge of the disk 5 and, optionally, in the edge of the dividing wall 4.
  • Fig. 2 With the aid of the embodiment shown in Fig. 2 , it is possible to have more than two components mix with each other.
  • the sizes of the product chambers A and B can be adapted to each other such that the proportions in which the components are to mix with each other will be realized. It is, for instance, also possible that the two product chambers B have mutually different volume contents.
  • the dividing wall 4, as shown in Fig. 1 is movable in the direction of arrow O after a component has flown from product chamber B into product chamber A under the influence of the pressure exerted on the product chamber B with the aid of disk 5 and has mixed with the component present in product chamber A in the storage condition.
  • a dividing wall 4a may have been provided in the packaging system, such as indicated by the broken line in Fig. 2 .

  • the dividing wall 4a may also be movable in the direction of the outlet opening 1.
  • Such a dividing wall 4a could also have been provided in the embodiment of the packaging system according to the invention shown in Fig. 1 .
  • the first predetermined pressure in a product chamber at which the closing element 3, 3a provided in the dividing wall is brought into an opened condition mainly depends on the extent to which the closing element is clamped in the dividing wall.
  • the closing element 3, 3a may also have been provided against an outer edge of a side of the dividing wall 4, 4a facing the outlet opening 1.
  • the closing element can be maintained in a closed condition by a pressure applied in product chamber A.
  • the closing element Upon realizing a pressure in product chamber B which is higher than the pressure in product chamber A, the closing element will be brought into the opened condition.
  • a movable dividing wall 4, 4a will move in the direction of arrow O.
  • the driving means 6 may also be provided with one or two bellows by means of which each of the product chambers B is reduced under the influence of the propellant with the aid of the driving means in order to increase the pressure in product chambers B.
  • a bellows optionally, an inflatable balloon may also be used.
  • the product chambers B themselves are substantially formed by a bag or bellows.
  • the dividing wall 4 itself to form an openable closing element 3.
  • the dividing wall is, for instance, manufactured from paper or plastic which can tear open.
