Definitions

  • the present invention concerns a container for flowable products, comprising a dispensing spout with openings which prevent leakage when said openings are not closed.
  • liquid or semi-liquid products, having a viscosity below 1 Pa.s at 20°C.
  • the container of the present invention is particularly advantageous for containing edible products.
  • the scope of the present invention is not exclusively limited to such edible products, and can also apply to non-edible products such as fabric and home care products, such as bleach, fabric care liquid products, household detergents.
  • packaging solutions typically comprise containers with a dispensing mouth that is reclosable with a closure elements, like a screw cap for instance.
  • a closure elements like a screw cap for instance.
  • the container is such that when the dispensing mouth is not closed, the contents can be spilled if the container is tilted, or generally if the contents comes in contact with the dispensing mouth. In such case, the contents directly flows out through the dispensing mouth.
  • sports closures comprise a dispensing channel which can be closed easily by pushing a closing element which is generally not detachable from the rest of the closure.
  • Such sports closures are widely know, and different systems are proposed, for instance push-pull closures, hinged closures, etc.
  • Such closures are complex and expensive to manufacture, hence a higher price for the product to the consumer, particularly in case the container is for a nomadic consumption of a product with a limited content volume.
  • they require a large amount of material for their different constitutive parts.
  • one major drawback is that such sports cap leak if the consumer does not close them.
  • valve closures Due to the drawbacks of sports closures, another type of closures was developed which comprise an elastomeric valve, like a slit valve. Such valve closures are reliable and their use in the food packaging industry increases, for instance for packing honey, ketchup, or the like.
  • One particular advantage which is of high importance is that such closures do not necessarily require an additional overcap to seal the valve.
  • the valve itself is sufficiently resilient to reclose after dispensing, so that even if the container is tilted, the contents in contact with the internal surface of the valve does not leak through. This is a clear consumer benefit.
  • the closure body is generally made out of polyethylene or polypropylene
  • the slit valve itself is made of a silicon or other similar resilient material, which must be assembled or co-injected with the closure body.
  • containers which are single-piece flasks made by extrusion-blowing of a thermoplastic such as polyethylene.
  • Such containers comprise a container body, which is manufactured together integrally with a detachable tip. When the tip is torn off by the user, a very tiny dispensing opening is created in the container walls, which allows for dispensing of the contents.
  • Such containers are widely used in the pharmaceutical industry, for providing monodoses (unidoses) for instance for local treatment by a collyrium (i.e. eardrops or eyedrops).
  • collyrium unidoses containers have an advantage that the contents, although liquid or at least very fluid, does not leak through the dispensing opening even if said contents is in contact with the internal surface of the dispensing opening.
  • such a container should allow a sufficient flow rate during dispensing, but at the same time, it should prevent leakage of the contents even when the dispensing opening is not closed by a closure system, and the container is tilted such that the contents is in contact with the internal side of the dispensing opening.
  • a container comprising a deformable container body with at least one compartment, for containing a flowable liquid, semi-liquid, or jellified product having a viscosity lower than 1 Pa.s at 20°C (preferably less than 500 mPa.s, more preferably less than 100 mPa.s), and at least one dispensing opening for dispensing said product, which is located in a spout element, said container having a capacity of at least 10ml, preferably at least 50ml, characterized in that the functional cross-section of said at least one opening is fixed and comprised between 0.002 mm 2 and 7 mm 2 , preferably between 0.008 mm 2 and 0.8 mm 2 , more preferably between 0.03 mm 2 and 0.4 mm 2 , and most preferably between 0.07 mm 2 and 0.2 mm 2 , such that said product flows through said opening only after an external force of at least 0.5 kg, preferably at least 1 kg, more
  • the deformation applied onto the container body surface is expressed as originated from a force exerted thereon, as it is supposed that the pressure applied onto said surface is evenly distributed across said surface.
  • the container comprises a plurality of dispensing openings, whose number is at least 6, preferably at least 12, more preferably at least 18.
  • the container further comprises a closure system associated to said spout element.
  • said closure system advantageously comprises a manually breakable tamper-evident means.
  • Said tamper-evident means can be for instance a laser-scored pre-cutting disposed such that said closure system can be torn-off in order to give access to the container contents through said opening.
  • the deformable container body can be a flexible film pouch, or alternatively it can be a plastic bottle with walls having at least one portion whose thickness is lower than 200 microns, preferably lower than 100 microns.
  • said bottle is preferably made of PET (polyethylene terephtalate) or PEN (polyethylene naphthalate), and manufactured by a stretch blow-moulding process from a PET, respectively a PEN preform.
  • PET polyethylene terephtalate
  • PEN polyethylene naphthalate
  • said deformable container body can be a bottle comprising deformable at least one accordion-shaped portion with bellows which can be deformed under force.
  • each of said at least one dispensing opening can take the form of a channel, having a length comprised between 0.1 and 20mm, preferably between 0.5 and 10mm, more preferably between 1 and 7mm.
  • the present invention is directed to a container 1 comprising a dispensing opening that is structured and designed such that:
  • the container 1 as illustrated in figure 1 comprises a deformable container body 2 having one compartment, for containing a flowable liquid, semi-liquid, or jellified product having a viscosity lower than 1 Pa.s at 20°C.
  • the container body shown in figure 1 is a flexible film pouch 2.
  • a spout element 3 is attached to the container pouch body 2.
  • the spout element is an injection moulded element made of a thermoplastic such as polyethylene (PE) or polypropylene (PP).
  • PE polyethylene
  • PP polypropylene
  • the spout element comprises a base which is sealed with the film pouch 2, such that the sealing is leaktight.
  • the spout element 3 comprises a plurality of openings which run through the thickness of said spout, so as to establish a fluid communication between the interior of the pouch, and the exterior.
  • the functional cross-section of the dispensing openings is fixed and comprised between 0.002 mm 2 and 7 mm 2 , preferably between 0.008 mm 2 and 0.8 mm 2 , more preferably between 0.03 mm 2 and 0.4 mm 2 , and most preferably between 0.07 mm 2 and 0.2 mm 2 , such that said product flows through said opening only after an external force of at least 0.5 kg, preferably at least 1 kg, more preferably at least 3 kg, is exerted onto the container body walls which is directed towards the inside of said body.
  • the dispensing openings illustrated in figure 3 are straight channels having a circular functional cross section, and having a length of about 15 mm.
  • the channels can be curved or comprise angled portions.
  • the number of dispensing openings will be chosen according to the viscosity of the product contained in the pouch, and also on the dispensing flow which must be obtained, i.e. depending on the type of use of the contents. For instance the output flow can be slower for viscous products such as culinary sauces for instance, whereas a liquid like mineral water should be able to flow sufficiently rapidly to allow a proper thirst quenching.
  • the number of dispensing openings can be a multiple of six, but not necessarily. In the example illustrated in figure 3 , the number of dispensing openings is seven.
  • the container body is a very thin-walled bottle 5 made for instance of a blow-moulded polyethylene terephtalate (PET) material which is obtained by stretch blow-moulding of an injected preform.
  • PET polyethylene terephtalate
  • the bottle walls 6 are flexible and can be deformed by hand squeezing. Therefore, the bottle wall thickness is preferably less than 100 ⁇ m.
  • the spout element 3 is clipped, sealed, or similarly attached in a leaktight manner to the bottle body.
  • the material which is used to manufacture the deformable container body is such that flow rates can be obtained which are sufficient to guarantee a proper dispensing of the product to a consumer, and such flow rates values can be obtained by applying a manual force onto the container body walls which is reasonable, i.e. compatible with use of the container by grown-ups, teenagers, adults and elderly people.
  • acceptable flow rates should be comprised within the range of 50-5000 ml/min, preferably 100-1000 ml/min, more preferably 200-500 ml/min.
  • reasonable force to be exerted onto the walls of the container body is defined as follows:
  • Forces are measured using testing appliance, method and conditions as follows: the pouch is placed on a flat surface; a force is uniformly applied on the pouch by placing different weights on the support plate.
  • Examples of flow rates, obtained when different forces are applied onto the surface of the container body, are shown in Table 2 below.
  • the product contained in the container body is water, at 20°C (its viscosity is 1.002 mPa.s).
  • the container body is a flexible pouch having a volume of 250ml, made of a multilayer plastic film having a total thickness of about 150 ⁇ m.
  • the dispensing openings have a circular functional cross section (i.e. diameter), similar to the embodiment described above with reference to figure 3 .
  • the container 1 is similar to the container described above in reference to figure 3 , but for the design of the dispensing openings.
  • the dispensing openings 9 have a non-circular cross section, more particularly a trapezoidal cross section. All openings are disposed in a star-shaped configuration, as can be seen in figure 4 , with their short end turned towards the centre of the star.
  • the spout element 3 can be constructed such that it comprises a closing system 7, which closes the dispensing openings 4 at least at the time of manufacture, filling, and during storage. Then, at the time of dispensing the consumer can remove the closing system 7 by tearing it off, by unclipping, unscrewing, or other similar operation as necessary.
  • the closing system 7 is manufactured as an integral distal element of the spout element 3, such that it can be detached along a weakness line 8.
  • the dispensing spout 3 is as shown in figure 3 , i.e. with open dispensing openings, ready for dispensing by squeezing the container body.
  • the spout element is meant to be rigid, it could also be envisaged to apply a soft spout element, made of an elastomeric material, or being a spongy material.
