Definitions

  • the present invention relates to a device for containing and dispensing a fluid product, comprising a container with at least one product space bounded by at least one wall for receiving the product therein, which product space is covered on a dispensing side.
  • the invention herein relates particularly, although not exclusively, to such a device with a container which can be realized at relatively low cost and can be applied in a relatively flat carrier.
  • a device of the type stated in the preamble is for instance known from German patent application DE 19.744.213.
  • a container enclosing a product space is there formed from a flexible plastic foil.
  • the product space is filled with a relatively thin fluid, such as a cleaning agent, preservative or aromatic substance.
  • a relatively thin fluid such as a cleaning agent, preservative or aromatic substance.
  • the container is arranged between a pair of cotton wool pads which are mutually connected around the container.
  • the container is thus fully integrated in a cotton wool body.
  • the known device is for instance held between thumb and index finger and a sufficient pressure is exerted on the whole in order to cause the wall of the container to burst.
  • the fluid will thus penetrate the cotton wool body, which wholly or partially absorbs the fluid and with which the fluid can then be applied to a surface for treating.
  • a drawback of the known device is however that it is not very suitable for reuse. Once it has been opened, the container is completely emptied into the two cotton wool bodies, which will then dry in the air. Nor is it possible, at least not satisfactorily, to dose the dispensing of liquid to the cotton wool bodies.
  • the known device moreover requires a relatively low viscosity in respect of the liquid contained therein, while thicker products, such as creams, pastes of gels in particular, will not penetrate sufficiently into the cotton wool bodies or be absorbed thereby.
  • the present invention has for its object, among others, to provide a device with a container for a fluid product which is suitable for reuse and which enables a user to dispense the product in dosed manner and which is also suitable for thicker, more viscous fluids such as for instance creams, pastes and gels.
  • a device of the type stated in the preamble has the feature according to the invention that an outflow opening of the product space is at least partially covered with at least a part of an assembly of, successively, a relatively stiff base layer and a relatively flexible further layer which are adhered to each other along a peripheral edge and lie freely against each other therein, that the base layer and the further layer inside the peripheral edge comprise respectively at least one first opening and at least one second opening, that the at least one first opening and the at least one second opening are arranged free of a mutual overlap, and that the at least one first opening is in open communication with the product space, at least during dispensing of the product.
  • the container thus comprises on the dispensing side a pair of stacked layers which lie against each other in a rest situation and thus close the product space to at least sufficient extent.
  • the two layers move apart relative to each other to form one or more outflow channels therebetween, along which the product can escape.
  • This outflow of liquid can be dosed in simple manner by applying more or less pressure.
  • the two layers return to their starting position against each other and thus close the product space once again.
  • a container can thus also be kept for a longer period of time and is available for repeated use.
  • a preferred embodiment of the device according to the invention has the feature that the peripheral edge at least substantially coincides with an edge of an outflow opening of the product space.
  • the base layer can thus be reached by the product over a full cross-section of the outflow opening, which product can then continue on its way via the opening(s) in the further layer.
  • a particularly practical embodiment of the device according to the invention has the feature that the base layer and the further layer comprise respectively a first foil and a second foil which are mutually adhered at least along the peripheral edge.
  • the first foil use is made here according to the invention of a relatively stiff, for instance relatively thin material, while a relatively flexible, for instance relatively thin material is chosen for the second foil.
  • a particularly simple embodiment of the device according to the invention has the feature that the base layer forms the wall of the product space, wherein the first opening comprises an outflow opening of the product space.
  • a single layer thus forms both the wall of the product space and the base layer in the assembly according to the invention, whereby an additional layer or foil is saved.
  • This has significant production engineering and commercial advantages, since the container and the base layer can thus be formed together from for instance the same base foil. Only the further layer, for instance likewise in the form of a foil, then need be arranged in order to obtain an operative assembly.
  • the base foil can for instance be given the correct form by vacuum-forming or other suitable thermoforming process, such as (low pressure) injection moulding.
  • a preferred embodiment of the device according to the invention has the feature that the base layer has a convex surface on a side directed toward the further layer.
  • the bulging base layer will here impart a tension to the assembly with the flexible further layer, which latter will thus shape itself at least substantially seamlessly to the surface of the base layer. A substantially vapour-tight closure of the container is thus obtained.
  • a further particular embodiment of the device according to the invention has the feature that, at least before being opened, an auxiliary fluid is received between the base layer and the further layer, in particular a relatively not very volatile, for instance at least oily liquid.
  • auxiliary liquid is advantageously made here of a fluid with low volatility so that it performs its closing action for a long time.
  • a hermetic closure of the product space is provided by a further particular embodiment of the device according to the invention, which is characterized in that an at least substantially hermetic breakable closure, in particular a peel-off, at least substantially vapour-tight foil, is arranged on a side of the assembly of layers remote from the product space.
  • a container which has been opened can thus be immediately recognized from a broken breakable closure, while up to this stage it closes the product space at least substantially hermetically.
  • a peel-off foil it is otherwise also possible here to apply a breakable layer which closes hermetically but breaks under sufficient external pressure, and releases the assembly.
  • Such a breakable closure is particularly advantageous in a device with various containers which each provide a determined, maximum dose of the product and which can thus be opened one by one.
  • the pressure required for moving apart the two layers of the assembly can be provided per se in various ways.
  • a particularly practical embodiment of the device according to the invention is however characterized in this respect in that the at least one wall of the product space is deformable, in particular can be pressed in or compressed.
  • a manually exerted external pressure can thus be applied to the liquid in the product space by deforming the wall of the container, this pressure then resulting in the two layers moving apart.
  • the wall When the force necessary for such a deformation is removed or ends, the wall will usually spring back wholly or partially to a starting position, which in turn has a suction effect on the further layer, which thereby nestles once again against the base layer and closes the product space, while a flow channel between the two said openings is here evacuated and thus remains at least to a significant extent clean.
  • a particular embodiment of the device according to the invention which is characterized in that the wall of the product space is structured with the clear intention of enhancing manual compressibility thereof.
  • a further particular embodiment more particularly has the feature here that the wall has a concertina structure.
  • the container comprises a unitary body with a recess bounded by a closed, flat upper edge and with a wall thickness which allows a manual deformation thereof.
  • the body is manufactured by thermoforming, in particular by vacuum-forming, from a plastic foil of at least substantially said wall thickness.
  • the device according to the invention has the feature that the container is provided at least around the dispensing side of the product space with applicator means for receiving the product from the product space and distributing thereof over a surface for treating.
  • the applicator means serve here to receive and then dispense the product after it has left the product space in dosed manner.
  • Such applicator means can for instance comprise a perforated layer or foil with which the product can be spread, although a further particular embodiment of the device according to the invention has the feature that the applicator means comprise an absorbent body, in particular a layer of optionally natural, unwoven textile fibres, and more in particular a layer of felt or a layer of cotton wool.
  • a felt(-like) layer or cotton wool(-like) layer in particular forms a substrate which is usually perceived as particularly pleasant for applying or otherwise processing for instance cosmetic products on the skin.
  • a further preferred embodiment of the device according to the invention has the feature that the absorbent body comprises a recess in which the container with the product space is received, and that the absorbent body has a thickness around the recess which extends beyond a bottom of the container.
  • Such a dimensioning of the enclosing body has the advantage that the device can be stacked smoothly with similar devices. The device thus allows exceptionally compact combined packaging.
  • a device according to the present invention will frequently find application as disposable article which after use will enter a waste flow intended for this purpose.
  • a further particular embodiment of the device according to the invention has the feature that at least substantially all parts thereof are biodegradable.
  • Materials which are particularly applicable in this respect are for instance based on cellulose or biodegradable, semi-crystalline thermoplastic plastics, referred to as PHA.
  • PHA poly(3-hydroxybutyric acid), or PHB.
  • a biodegradable plastic such as polylactic acid (PLA) is also suitable as an alternative to polyethylene terephthalate (PET), much applied in blister packs, as a starting material for one or more parts of the container of the device according to the invention.

  • a moulded body of a suitable thermoplastic plastic such as polypropylene or polyethylene
  • the foil thickness is roughly a wall thickness in the end product and allows a manual deformation of the finished product without considerable effort.
  • Product space 11 is bounded all around on a dispensing side by a closed flat top edge 12 on which is arranged an assembly of successively a base layer 21 and a further layer 22.
  • a relatively stiff foil of polyester, high-density polyethylene or polypropylene is applied here for the base layer with a thickness of about 20 to 80 micrometres in order to impart a certain form-retention thereto.
  • the further layer 22 comprises a considerably more flexible foil 22, for instance of low-density polyethylene (LDPE or LLDPE), with a thickness of about 5 to 30 micrometres.
  • LDPE low-density polyethylene
  • the desired difference in flexibility can otherwise also be realized, or even wholly realized, by making use of different thicknesses of the foils or by modifying the starting materials by providing different (crystal) structures therein or applying softeners and/or fillers.
  • An applicable example of a material which is suitable for such different embodiments is for instance PET, which has both crystalline (CPET), amorphous (GPET) and non-woven, fleece-like embodiments.
  • Base layer 21 comprises a pattern of first openings 31 , while a pattern of second openings 32 is arranged in the further layer. Both patterns are here carefully adapted to each other so that the first and second openings do not have mutual overlap anywhere, this being shown clearly in both top views of figures 3 A and 3B.
  • First openings 31 are here shown transparently with dotted lines between second openings 32 drawn in full lines.
  • the patterns shown therein are otherwise shown solely by way of illustration, and diverse other patterns or only individual first and second openings can also be applied within the scope of the invention.
  • the two layers 21,22 are connected to each other in vapour- tight manner and to a top edge 12 of the wall of container 10 which wholly encircles product space 11. Further layer 22 lies freely against base layer 21 within peripheral edge 13. Because base layer 21 has a slight bulge with a concave surface, further layer 22 lies against base layer 21 here in relatively tight and closing manner. If desired, a possibly remaining gap or intermediate space between the two layers 21,22 can be closed with an auxiliary liquid, such as for instance a silicone oil, which is for instance applied later to further layer 22 and will be suctioned in capillary manner between the two layers 21,22. In the shown situation there is therefore no, or hardly any, open communication between first openings 31 and second openings 32, and product space 11 is sufficiently closed.

  • a breakable closure in the form of a manually removable, vapour-tight foil 23 of for instance aluminium or a plastic such as optionally coated polyester.
  • Foil 23 is for instance ultrasonically fused with further layer 22 or adhered thereto by glueing and provides a hermetic, vapour-tight closure of the whole in order to increase the storage life of a content of the container.
  • a pull tab 24 is formed on foil 23 with which foil 23 can be peeled off if desired in order to open the container.
  • a thus opened container is shown in figure 2.
  • a wall of the container as shown by way of illustration, is here manually deformed in order to thus build up a pressure inside the product space which results in flexible further layer 22 moving away from base layer 21.
  • a fluid product 40 received in product space 11 thus finds a number of flow paths, indicated schematically in the figure by arrows, via first openings 31 between the two layers 21, 22 and to second openings 32, from which the product can escape.
  • the dispensing of the product can here be dosed as desired.
  • both layers 21,22 slacken and once again take on the mutually closed state as shown in figure 1. In this situation the container can be stored for a long time and is thus suitable for repeated use.
