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.

  • 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.

  • 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 openi ngs wh ich run through the thickness of said spout, so as to establish a fluid communication between the interior of the pouch, and the exterior.

  • 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 nu mber of dispensing openings will be chosen accord ing 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.

  • 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:
  • minimal force is comprised within the range of 1 -5kgs, preferably within 2-4kgs, more preferably it is set at about 3kgs. With such values, we ensure that for volumes below about 3 litres of very fluid products (e.g. water), flowing does not occur just by gravity, and
  • maximal force is comprised within the range of 20-40kgs, preferably within 25-35kgs, more preferably it is set at about 30kgs. According to tests, 30kgs is a very intense grip to achieve for a teenager or an adult, and certainly not reachable for a baby or a very old person.
  • 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.
