Definitions

  • the present invention concerns an assembly for two products to be mixed just prior to use.
  • the primary object of the invention is to keep separated an additive from the main part of the product filled in a separate container until the product has to be consumed, at which time the additive is released into the base product.
  • Such solutions are already known , for example in the patent application WO 01/05675.
  • This patent concerns an assembly for two products to be mixed just prior to use comprising a container comprising an upper part with a cap, a lateral wall and a bottom, an aseptic, UHT, sterilised or pasteurised product filled in said container and completely sealed on the upper part with a membrane and a supplement disposed in a second container.
  • UHT aseptic, UHT, sterilised or pasteurised product filled in said container and completely sealed on the upper part with a membrane and a supplement disposed in a second container.
  • There are several different embodiments in this patent application for the disposition of said second container. The problem with this solution is that the mixing of both components is not efficient enough.
  • the present invention concerns an assembly, wherein by the mixing of both components, the consumer has an efficient mixing with a normal shaking of the assembly. Furthermore, the present invention is more convenient and safer.
  • the present invention concerns an assembly for two products to be mixed just prior to use comprising a first container comprising lateral walls, a base product filled in said container and completely sealed with a first membrane on the top of the container and a second membrane on the inside and near the bottom of said first container, a second container containing a supplement and comprising a flexible formed bottom, a third membrane sealing the periphery of the flexible bottom and cutting means inside said container, said second container being in the internal space of the first container and near the second membrane and a piston disposed below the second container and at the bottom and inside the first container, for pushing the flexible bottom of the second container to pierce the third membrane of the second container and the second membrane of the first container.
  • Another great advantage of the invention is that the two products are each completely sealed and closed and packaged together as one entity but kept totally separate up to time of consumption.
  • the assembly according to the invention is furthermore very convenient for the consumer : he has to push the piston , so that the bottom of the second container with the cutting means moves to pierce both membranes of the first and the second container.
  • the cutting means are sufficient in dimension to operate a really large opening to allow the supplement to be easily mixed with the base product. After the shaking of both components, the consumer can then open the first membrane of the first container and the product is ready to use.
  • the inside of the first container presents a shoulder increasing the diameter of said container from the top to the bottom.
  • the second membrane of the first container is sealed inside and on the shoulder of said container and the second container is sealed on said second membrane.
  • the third membrane of the second container has a smaller diameter than the formed bottom, so that the formed bottom is sealed against the second membrane of the first container or the third membrane of the second container has the same diameter as the formed bottom and in this case, the third membrane is sealed against the second membrane of the first container.
  • the second membrane has a smaller diameter, so that it is sealed also on the shoulder of the first container, but in this case, the second container is directly sealed on the shoulder of said first container : in this case, there are two possibilities.
  • the third membrane of the second container has the same diameter as the flexible bottom and in this case the third membrane is sealed on the shoulder or the third membrane has a smaller diameter than the flexible bottom and in this case , it is the periphery of said flexible bottom which is sealed to the shoulder of the first container.
  • the inside of the first container is substantially cylindrical and the second and third membranes are sealed substantially near to each other on the inside wall of said container.
  • the inside of the first container presents an annular rim on which the second and third membranes are sealed.
  • the first membrane sealed on the top of the first contianer is made from a compressible material or a material with collapsible shape for pressure release during the piercing process.
  • the cutting means in the second container it is possible either to have said cutting means integral or not integral with the flexible bottom of said second container.
  • the inside of the first container must include means for stopping the cutting means to fully enter the filled part of the first container .
  • the base product in the first container is normally a powder, liquid or viscous product.
  • the supplement can be a powder, a liquid, a viscous or a compacted product.
  • the first is that the shelf life can be extended .
  • the second is that it is possible to fill new products, which are normally unstable and because of the mixing just prior to use, it is possible to consider a packaging of said products.
  • the third is already mentioned above and concerns the product quality of separated packaged products.
  • the base product and the supplement there is no criticality and it is only dependent on the type of product which is considered. For example, it is possible to carry out an aseptic filling, or proceed to UHT treatment, sterilisation, pasteurisation or no heat treatment at all.
  • the base product and the supplement can be used per se, or filtered or chemically treated.
  • the base product can be of any kind of food, petfood, nutritional, clinical and medicine products, like products taken from the group consisting of a milk-based product, juice, fruit product, mineral water, stilldrink, enteral feeding, parenteral feeding, petfood, soup, sauce, dressing and mayonnaise.
  • the supplement can be any type of supplement, which provides an added value to the basic product.
  • the supplement is taken from the group consisting of a foodstuff, minerals, vitamins, flavours, prebiotic, probiotic, energetics, like natural ingredients and functional ingredients, supplement for infant feeding, like hypoallergenic powder, alone or in combination.
  • the cutting means present in the second container are not critical. These means are either blades or needles or any other tools having a piercing functionality.
  • the piercing means are in the form of blades extending radially, for example 2 to 10 blades.
  • the first container can be rigid or semi-rigid. As rigid or semi rigid package, it is possible to use bottles, cups or jars.
  • the material of this container could be molded or injected plastic.
  • PP polypropylene
  • PE polyethylene
  • PET Polyethylene terephthalate
  • the piston is from a rigid material, like molded or injected plastic. This material could be PP or HOPE (high density polyethylene) .
  • the cutting means are also rigid material , like PP, HDPE or PS (polystyrene) .
  • the flexible bottom material and the membranes used could be mono-materials, laminates or coextruded materials. It is possible to take any type of material known in the art for example aluminium laminate, PE, Polyamide, PP, PS, polyethylene terephthalate .
  • the ready to drink product can be foreseen for babies, for infants, for adults, for old persons and for pets.
  • the present invention concerns further a tamper-evident device comprising a main container with an upper rim and a bottom or a lower rim and a top , a closure on the top of the container or a piston on the bottom of the container with radial tabs extending either on the upper rim or on the lower rim of said container and - a shrink or stretch sleeve covering the tabs of either the closure or piston.
  • the radial tabs are on said closure : you can then see if the package has been opened if the radial tabs are above the shrink or stretch sleeve.
