Definitions

  • the present invention relates to Pressurisable containers for storing and ejecting liq- uid, the container comprising a) a front wall having or surrounding a cavity corresponding to the form of an open vessel, b) an opening in the front wall adapted for ejection of the liquid from the container, said opening defining a container axis, c) optionally a sealing over the opening adapted for temporary use, and d) a rear wall closing and sealing the open part of the front wall vessel to confine a space for the liquid in the container, the rear wall running at least partially perpendicular to the container axis and being displaceable or deformable for movement towards the opening to pressurize the container liquid.
  • the invention also relates to methods for container manufacture and devices and methods for ejecting liquid from the containers.
  • High chamber pressures e.g. to give high jet speeds or atomizing degrees, may counteract the cost aspect by requiring thick walls of special design or elaborate supports for the chamber or counteract the targeting by rupture, instability or dislocation of the opening. et coherence may require a precise opening channel inconsistent with minimum material and manufacturing conditions.
  • High dosing precision requires complete chamber emptying and small losses, in turn requiring rapid pressure build up and fall, placing high demands on cavity stability and controlled collapse of the pressurizing wall. Secondary factors also need consid- eration.
  • the US patent specification 4090642 describes a tape having multiple pockets for a flowable material and represents liquid dispensing with low delivery and control requirements since the flowable material is only to be squeezed out on the tape surface for contact application to the skin.
  • the US 5497763 specification relates to a system including a similar multiple dose tape for atomizing liquid to be inhaled. The delivery requirements are still low as atomization takes place with a separate vibrator and the demands on the tape reduce to liquid outflow through a porous membrane.
  • the GB 2255918 specification similarly relates to droplet formation for inhalation purposes but liquid atomization here takes place by forcing the liquid through nar- row container openings.
  • a main object of the present invention is to avoid the abovesaid disadvantages of hitherto used container systems.
  • a more specific object is to offer a unit dose sealed container system suitable both for liquid storage and liquid delivery under high control and quality de- mands.
  • a further object is to provide such a system meeting high demands in respect of liquid speed, precise targeting, jet coherence, rapid stream rise and fall, fast delivery, small losses, precise dosing and/or complete container emptying.
  • Another object is to offer a system allowing high chamber pressures with maintained container integrity and without rupture, instability or dislocation of the opening.
  • Still another object is to offer a system allowing con- trolled collapse of the pressurizing wall.
  • Yet another object is to offer a system useful for varying degrees of liquid stream momentum, e.g.
  • Another object is to offer system containers of low cost in material, component manufacture and filling. Still another object is to offer containers of high rigidity and stability. Yet another object is to provide such con- tainer designs suitable for multiple container units useful for sequential delivery of doses. Another object is to provide containers facilitating dispenser device design and requiring limited support at delivery. Another object is to provide a system easy to handle and convenient to operate for the end user.
  • a stretchable material in the wall will allow the wall to increase its surface during collapse, hereby avoiding rupture, permitting dynamic adaptation to any ram or hammer tool surface used for forced displacement of the wall and allowing the wall to conform to the opposite container cavity surface, all serving to give controlled pressure response, including initiation, continuation and fall, and precision in dosing and container emptying.
  • Manufacturing advantages are reached among others in that the wall form facilitates its production, its sealing to the front wall in filling procedures and its joint attachment to several containers in multiple compartment units or packages. Handling, convenience and dispenser device design advantages are reached in that the initial wall shape may be used to give smooth rear wall surfaces and does not build on the boundaries of the material used for the vessel front wall design. Said front wall is relied upon for overall container static and dynamic rigidity.
  • the present vessel wall can be designed freely and needs not depend on the curvature of pressed structures for rigidity, can have a wall thickness at each location adapted to its functional object and needs not be locally weakened by stretch operations and can have an integral opening determined by design and not by manufacturing necessities.
  • Wall stability is essential to volume control and the possibilities for consistent emptying.
  • Wall and opening strength is essential to pressure resistance and the operative range of the system, reliable targeting and stable and coherent liquid jets. It also reduces the needs for extensive container support arrangements in the dispenser device and facilitates sequential feeding of containers into a shoot position. If the rigidity advantages are used to avoid bulb wall parts, dispenser container seat and feeding mechanism can be further simplified.
  • the vessel wall can for example be implemented as the resulting structure when forming the container cavity in an otherwise flat or single-curved plate, al- lowing both single and multiple container units of high structural rigidity and simple outer form, to the benefit of manufacture, dispenser design and end user handling, allowing free cavity designs e.g. for suitable flow characteristics and device head design as well as allowing opening designs of any length and form with high dynamic stability. Similar advantages are obtained if implemented with substantially constant vessel wall thickness or with increasing wall thickness when moving lateral out from the opening location of the wall.
  • the vessel walls with opening in place can be manufactured as an integral, single material, structure e.g. by heat molding in common plastic tools, without need for stretch operations or separate nozzle forming steps, and are easily filled with liquid and sealed by the rear wall. Further objects and advantages of the invention will be evident from the detailed description hereinbelow.
  • single-curved shall be understood as any form of a plane or surface obtainable from the same plane in flat form, without stretching or shrinking any part thereof in any direction within the plane, i.e. with maintained total surface for both the whole plane and any part thereof.
  • a "double-curved" plane or surface can only be obtained from a flat plane if deformed by stretching or shrinking.
  • a curvature shall be regarded “continuous” if the change in curvature is constant or has a smooth variation and shall be regarded as “discontinuous” if there is a sharp change in the plane direction.
  • a cylinder surface or a corrugated surface are single curved as they can be formed from a non-elastic sheet, e.g. paper sheet, by pure bending whereas the surface of a sphere or saddle cannot be so formed without stretching and accordingly are double- curved. All these surfaces are continuous by having smooth curvature changes whereas for example a sheet with sharp folds are discontinuous at the fold lines.
  • system shall be understood to refer to the invention generally, when including its parts, such as the container and dispenser devices therefore, as well as methods for part operation and use.
  • positional and directional statements for both the container and the delivery device such as “axial”, “front” and “rear” and “forward” and “rearward”, shall be understood with reference to the liquid delivery direction, with respect to which a line centered in the container opening and drawn along the main or average delivery direction shall be regarded as the system "axis” along which axis the liquid is delivered in the forward direction.
  • the container can be said roughly to include a front wall and a rear wall between which the container space, or enclosure, for the liquid is confined.
  • the container space is formed mainly between the front wall and the rear wall and in- eludes a cavity part formed in, or surrounded by, the front wall.
  • the space available for the liquid may be larger than the volume of the cavity proper, e.g. additional small volume in the opening and in a rearward protrusion or curvature of the rear wall, it is preferred that the cavity constitutes the major part of the space, especially when the rear wall in the preferred manner is substantially flat or single-curved.
  • the cavity surface preferably has the shape of the space of a vessel, opening towards the rear wall and having its closed bottom toward the front wall. Among others in order to facilitate complete emptying and form adaptation between cavity and driving ram, it is preferred that the cavity has little, and preferably no, undercut parts when seen from the rear side.
  • vessel surface parts being parallel with the cavity axis, e.g. cylindrical parts, but preferably the surface widens all the way from the axis and laterally outwards, to create a generally concave deepening when seen from the rear wall side.
  • the surface may have sharp discontinuities, e.g. between an axial cylindrical surface and a more flat front part, it is preferred e.g. for rigidity reasons that the surface is substantially smooth and continuous.
  • the cavity shape in cross- section planes perpendicular to the axis can have any shape, e.g. oval or polygonal, although preferably circular. Suitable overall forms are that of a dome or segment of a sphere.
  • the space may be divided into two or more separate chambers, e.g. for sequen- tial delivery or for mixing in connection with delivery, for example by use of interior walls running perpendicular or parallel with the axis. Such walls can be manually removable before actual delivery or may be rupturable in connection with delivery.
  • adjacent containers may contain different liquids and eject substantially simultaneously, either as two dis- crete jets or jets mixing in connection with ejection, e.g. by openings arranged offset and close to each other or directed towards each other.
  • the front wall is preferably more rigid than the rear wall, by comprising more rigid materials and/or material of thicker dimensions.
  • the front wall provides the container and its opening with rigidity and stability and preferably the front wall alone is able to provide such rigidity, leaving the rear wall design free for other considerations.
  • the front wall can have a variety of configurations.
  • the front wall may have a roughly constant thickness when measured normal to the cavity surface, making the front wall shape about congruent with the cavity surface. It is preferred, however, that the wall thickness measured as stated has a variation and preferably so that the thickness increases when moving away from the axis. This gives the container as a whole a high targeting and pressure sustaining stability while allowing a short and low friction opening design.
  • a preferred way of arranging for abovesaid variation in wall thickness is to make the front surface of the front wall substantially flat or single-curved, flat being most preferred, giving a lot of manufacturing and handling advantages as indicated. It is further preferred that also the rear surface of the front wall in the neighborhood of the cavity, and disregarding the form of the cavity proper, is single-curved and most preferably flat, giving similar manufacturing and handling advantages.
  • the flat or single-curved surfaces allow attachment thereto of origi- nally flat sheets, films or foils without stretching thereof, e.g. a sealing film on the front surface and the backing rear wall on the rear surface of the front wall.
  • the front and rear surfaces are parallel or concentric respectively, giving e.g. overall plate or cylinder type structures, having good rigidity, handling and manufacturing properties.
  • the opening design can vary depending on the nature of the liquid stream to be pro- symbolized, e.g. an atomized spray or a concentrated stream to remain coherent or to break up into a linear stream of discrete droplets. Also the stream speed may vary from high penetrating to low impact surface delivery. Several or multiple openings can be provided, e.g. to produce a controlled shower, although for most applications a single opening is preferred.
  • the opening geometry can be that of a simple tube, diverging, e.g. for assisting in a distributed spray, converging, e.g. for assisting in a coherent stream to be formed, or a combination, such as a ven- turi type of channel.
  • the desirable front wall thickness at the opening area can still be controlled, e.g. for rigidity purposes, e.g. by cutouts around the opening, preferably on the front surface of the front wall, also assisting in attaching a sealing film over the opening in a manner not interfering with the opening proper.
  • the positioning of the opening with respect to the cavity can be asymmetrical, for example laterally offset towards the cavity side e.g. for mixing of adjacent jets, although normally it is preferred that the opening is symmetrically arranged with respect to the cavity, e.g. concentric with any cavity symmetry.
  • the multiple container package is a substantially rigid and self-bearing structure, among others giving advantages in connection with the delivery device.
  • a rigid structure can be obtained by joining the individual containers by rigid joints but a preferred way is to utilize the rigidity of the front wall as de- scribed by providing an enlarged front wall structure and provide several cavities in the structure, among others facilitating manufacture of multiple containers and allowing a smooth and non-complicated exterior.
  • the attachment of films over these surfaces is further simplified, especially if the container surfaces lies in the same plane since an undi- vided sheet material can then be attached to several, and preferably all, of the individual containers of the structure, e.g. a common foil attached as rear wall to the rear surface of structure or a common peel sheet over the container openings at the front surface.
  • the overall shape of the front wall structure for multiple containers can take a variety of forms.
  • a single-curved form for example can take the form of a partial or complete cylin- der, allowing many containers on a limited volume and giving a very rigid structure.
  • the container openings can be arranged on the cylinder exterior, e.g. if the dispenser device ram is arranged to hit from inner or concave side of the full or partial cylinder or if openings are provided diametrically opposite each rear wall for ram access therethrough from outside the cylinder.
  • the container openings can be arranged on the cylinder interior, e.g. for simple exterior ram access to the rear wall and also in this case a diametrically opposite hole can be provided for passage of the liquid jet.
  • Essentially flat front wall structures give advantages in manufacture and delivery device design.
  • the shape may for example be rectangular, square or round.
  • the round "disc” shape has been found particularly beneficial, among others in connection with the delivery device where sequential feeding of the containers into a shoot position can be made by simple rotation in a "revolver” type manner, the absence of any particular start position facilitates handling and counting arrangements and allows for self-centering properties.
  • the layout of the multiple containers on the available structure surface can be made in various ways.
  • the containers can be arranged in a row or line, e.g. to avoid two dimension feeding.
  • several rows can be provided along several lines in two dimensions, e.g. parallel or concentric, to allow for a compact container arrangement.
  • the above design considerations for the front wall mainly apply to the parts occupied by containers, but other structures may be included for secondary purposes, e.g. for gripping, holding, centering or feeding discrete or multiple containers, in manufacture, in the delivery device and by the user, for adhering or removing sealing film etc. and these parts can be de- signed freely for their respective purposes.
  • the front wall is preferably made from suitable inert plastic materials such as polyethylene or polypropylene, possibly with reinforcing fillings of e.g. glass fibres, and can be manufactured in various ways, e.g. the cavities with opening can be made by machining in a raw material blank but the structures described can easily be formed in one step, e.g. by pressing although preferably by injection molding since all structures, including the opening, can be obtained with a dividable molding tool.
  • the front wall can be made of a laminate or other composite material a single material is generally sufficient.
  • the rear wall serves the purposes of sealing the rear part of the container before ejection of the liquid and allowing collapse of the cavity during ejection.
  • the rear wall should run at least partially perpendicularly relative the opening axis, i.e. forming a non-zero angle therebetween and preferably runs substantially perpendicularly thereto.
  • the requirements on the rear wall material for sealing purposes depend on the particular application and liquid involved but generally it is desirable that the wall material is highly impermeable. It is also desirable to avoid solvents and other volatile components, both in the wall material and when attaching the rear wall to the font wall and preferably these parts are joined by heat sealing rather than by glue or adhesives.
  • the rear wall can be deformed without rupture, and most preferably be deformed to such an extent that it can fill out and conform to the inner surface of the cavity.
  • the requirements for deformability can be reduced if the rear wall film is folded, e.g. in a continuous corrugated manner or in a discontinuous folded manner, i.e. in both cases with maintained single-curved shape, e.g. along single or multiple parallel lines over each container, to allow for unfolding as part of the deformation.
  • the rear wall when attached has substantially the same shape as the rear surface of the front wall.
  • the deformation during ejection will result in that the rear wall flat or single-curved shape is at least to some extent changed into a double-curved form, requiring some stretching of the material.
  • the stretching and deformation can be elastic, as in a rubber sheet, e.g. if repeated use is intended, but is preferably at least partially and preferably substantially plastic in an irreversible manner, e.g. in order to avoid reuse of disposable containers or to prevent aspiration of air or liquid remains into the container after use.
  • the rear wall preferably has the form of a sheet, film or foil of even thickness, which preferably is small compared to the front wall.
  • the sheet may consist of a single material but preferably a composite material is used to meet all the requirements indicated.
  • the sheet is a laminate.
  • the laminate comprises at least one imper- meable and diffusion retarding layer, preferably a metal layer such as an aluminum layer, and at least one stretchable layer allowing deformation, preferably a plastic layer, e.g. of polyethylene, optionally also a heat sealable layer if the plastic layer does not have this property.
  • a plastic layer e.g. of polyethylene
  • a seal can be formed integral with the front wall, e.g. by molding so as to leave a membrane of material somewhere in the opening duct.
  • a separate peel layer is provided for removal prior to ejection, and preferably attached to the front surface of the front wall.
  • the sealing can be made to a limited area sur- rounding the opening.
  • the layers individually removable for each container e.g. by use of separate films, pre-cut films or separate tongues, e.g. in a star shape for a round disc.
  • the film material similar considerations apply as for the rear wall material, although the film need not be deformable by stretching and the demands on impermeability can be slightly reduced in view of the small opening area.
  • the parts described should be joined and liquid filled into the cavity to form a pre- filled sealed container, typically containing liquid for a single dose to be delivered.
  • the preferred way is to fill the cavity from the rear side of front wall before attachment of the rear wall.
  • a useful procedure is then to adhere the sealing film over the opening or openings, pos- sibly under welding action, filling liquid into the container cavity from the rear side and adhering the rear wall over the filled cavity, again possibly under welding action.
  • these steps are made in the order mentioned.
  • the invention contributes in several ways to the efficiency and simplicity of such a procedure, particularly in contrast to blister type manufacture and filling.
  • flat sheets type materials can be used for the seal- ing film and the rear wall, allowing flat or single-curved adherence with equally simple flat or roll type tools and allowing adherence over several containers in multiple container structures and no stretch or other material deformation steps are necessary.
  • Adapted welding action e.g. heat
  • sealing heat for front and rear materials has to be applied through a peel layer, over-adhering the peel layer, prolonging the process, possibly affecting the liquid present, and increasing product tolerances.
  • a delivery or dispenser device for ejection of the liquid from the containers can generally be said to comprise a housing with a seat for the container or container structure, a ram movable in relation to the housing in a direction substantially axial to the container when in the seat, an actuator arrangement operative to drive the ram.
  • the housing shall be understood in broad sense and may take a variety of forms.
  • the device housing represents the point of reference for the container position and the movements described, such as the ram used for collapse of the container rear wall and for forces applied by actuating means performing said movements, whereat the force is applied between the housing and the moving part.
  • the minimum functional requirement is that the housing offers a support or platform for the container and movable parts and the actuating means providing the movements and forces.
  • the housing forms a container at least partly embracing the parts and preferably also to such an extent that only the features designed to be controlled or monitored by the operator are externally exposed, to give an overall convenient design to use.
  • the housing should contain a seat for a container or several containers, the minimum requirements on which is that at least the container to be emptied is kept fixed in relation to the ram, preferably so that the container axis and the movement axis for the ram are parallel and most preferably coaxial with respect to the ram part to hit the container rear wall.
  • the seat should be able to accommodate containers with the characteristics described herein, e.g. with the shapes and sizes exemplified.
  • the seat preferably supports the container against forward forces from the ram and preferably also against some rearward and lateral forces.
  • the seat preferably allows the entire rear wall surface over the cavity to be exposed to the ram and should also expose at least the opening or openings on the front side of the container not to obstruct the liquid stream, although the rigidity of the present containers do not require any heavy support.
  • the seat is also designed to allow easy exchange of discrete containers, or sequential movement of the individual containers of a multi -container structure, into the active position of the seat, e.g. by having a track in which the structure can be moved in one or two dimensions.
  • guid- ing arrangements are provided to secure good alignment with the ram axis in order to reach high delivery precision intended, e.g. structures provided in connection with each container on the package for cooperation with at least one corresponding locking structure on the housing, seat or preferably ram, arranged for interlocking at proper alignment. Locking therebetween can with preference be associated with a signal to assist stop in correct position, e.g. tactile or audible signal in manual operation or a mechanical or electronically detectable signal in automatic operation. Additionally it is preferred to include a counting arrangement, again manual or automatic, mechanical or electronical, designed to keep track on the number of containers used or remaining and warning for or preventing reuse of already emptied contain- ers.
  • the ram may include a ram head and piston arrangement for moving the ram head along the movement axis.
  • a ram head and piston arrangement for moving the ram head along the movement axis.
  • the ram head can be surrounded by a support, e.g. a tube structure in which the ram head travels, which is preferably also abutted around the cavity to seal the space between ram head and cavity at least during the rear wall collapse movement, e.g. to allow high pressures or re-za leakage risks.
  • the piston part of the ram is generally not critical to the dynamics of the ejection but rather for propulsion and will be described in connection with the actuator system.
  • the ram can be propelled by use of a variety of mechanisms and energy sources.
  • the mechanism can be operated directly with manual energy, in which case, however, it is pre- ferred to provide an leverage or gear exchange to amplify or transform force or speed, preferably towards lower speed and higher force.
  • it is generally preferred to have automatic function in the sense that after operator triggering the propulsion takes place automatically, and preferably irreversibly, by use of stored energy.
  • the energy may be stored in any way, e.g. in a mechanical spring, a gas spring or gas generator, as electrical energy or a combination thereof.
  • the energy may be transmitted to the ram by suitable motor or transmission means, e.g.
  • electric motor or solenoid type motor for electrical energy
  • a piston and cylinder arrangement for gas springs or gas generators and rotation axis or plunger for coiled and helical springs respectively.
  • at least the ram head, and preferably parts of the ram piston are prevented from rotation during forward movement, which can be secured by any known guiding structures, such as a non rotation symmetric part cooperation with a complementary part, the parts being positioned on ram and housing respectively.
  • a preferred transmission component for propulsion of the ram is a screw and nut arrangement, one of which is positioned on the ram and the other on the motor side of the transmission.
  • the necessary speed, force and movement characteristics for the ram depends on a number of conditions, such as the nature of the container parts and opening, the particular application implementation, e.g. surface or penetrative delivery, the viscosity of the preparation, e.g. aqueous solutions or ointments, etc. and general statements cannot be given.
  • the energy sources, motor means and transmissions exem- plified can be adapted to each need. It has also been found beneficial to include a damper, e.g.
  • a dash pot a linear damper, a flow valve, a magnetic damper etc.

  • the ideal speed is to some extent dependent on the drop size used but as a general rule the drops should be able to traverse at least 1 cm, preferably at least 3 and most preferably at least 5 cm through air by own momentum, incorporating reasonable distances between opening and target.
