Definitions

  • the present invention relates to a procedure for the manufacture of strips of vials for fluid products, particularly for medical, pharmaceutical, cosmetic, food products or the like.
  • vials made of plastic material generally polymer material
  • plastic material generally polymer material
  • the known vials generally comprise a containment body of a predetermined dose of product, of a substantially tubular and elongated shape, which has an end provided with a neck at the top of which is defined a product dispensing mouth.
  • the opposite end of the containment body has an opening able to introduce the product, which is closed after filling, e.g., by sealing.
  • Closing means removably associable with the vials at the neck, allow occluding the dispensing mouth.
  • the containment body and the closing means can be made separately using forming techniques such as injection molding, and subsequently assembled together, or, alternatively, they can be made in a single body piece and subsequently separated before being used by a user.
  • the containment body also has a pair of fins which are able to make it easier for the user to grip the vial, and which extend, in a diametrically opposite direction the one to the other, from the outer lateral surface of the containment body itself.
  • the known vials in plastic material are usually made in series to form a so-called "strip"; the fins of the containment bodies of two successive vials are in fact temporarily associated with one another at easy-to-tear weakened-section connection lines, which permit separating one vial from another.
  • Strips of this type are shown, e.g., in patent document WO 2009/147484, wherein at the vial dispensing mouths, applicator elements are provided, which are spatula shaped or with other shape and which help the user to distribute the fluid product coming out of the dispensing mouths.
  • Such applicator elements can be made separately from the containment bodies or in a single body piece with them.
  • the applicator elements and the containment bodies must necessarily be made from a same material, and this is a big restriction as regards the operating versatility of the applicator elements, considering that the need is often felt to have containers with parts having different characteristics from others.
  • sterile fluids are normally supplied in large glass or plastic bottles, which are chemically inert materials able to safeguard the sterility of the fluids contained in them.
  • the bottles are normally closed by means of a closing element called “stopper”, which is inserted in the bottle access mouth.
  • the closing element is made of rubber to allow penetration by means of a pointed sampling element, such as, e.g., the needles of hypodermic syringes and the spikes of infusion lines, thereby permitting the sampling and exit of the sterile fluid.
  • a pointed sampling element such as, e.g., the needles of hypodermic syringes and the spikes of infusion lines, thereby permitting the sampling and exit of the sterile fluid.
  • Bottles of this type are described in EP 0 819 617, EP 1 044 135 and WO 2009/144553.
  • the main aim of the present invention is to provide a procedure for the manufacture of strips of vials for fluid products, particularly for medical, pharmaceutical, cosmetic, food products and the like which allows, in an easy, functional and economical manner to make vials in the form of a strip which are of increased convenience and versatility of use with respect to the products of known type.
  • Another object of the present invention is to provide a procedure for the manufacture of strips of vials for fluid products, particularly for medical, pharmaceutical, cosmetic, food products and the like, which allows to overcome the mentioned drawbacks of the prior art within the ambit of a simple, rational, easy and effective to use as well as affordable solution.

  • Figure 12 is an axonometric, partially sectional view of the strip of vials obtained from the mold of Figure 8.
  • reference number 1 globally designates a strip of vials for fluid products obtainable through the manufacturing procedure according to the invention.
  • fluid products are not only meant liquid products but also viscous products, e.g., in the state of paste or gel, and powdered products, in particular very fine powders with great fluidity.
  • the strip 1 in practice, consists of a group of vials 2 integral with one another and joined along specific easy-to-tear weakened-section connection lines 3.
  • Each vial 2 comprises:
  • first end 4a able to define a dispensing mouth 5 of the fluid product; and a second end 4b opposite the first end 4a.
  • the second ends 4b of the vials 2 obtained at the end of the present procedure are open and can be used as mouths for introducing the fluid product; the closing of the mouths is achievable, e.g., by crushing and sealing the relative edges and is done once the fluid product has been introduced, before introducing the strip 1 onto the market.
  • Each vial 2 furthermore, has at least a spacing fin 6, normally two, extending from the respective containment body 4 and which is associated with at least a spacing fin 6 of an adjacent vial 2 along one of the weakened-section connection lines 3.
  • the procedure according the invention first of all comprises a step consisting in providing at least a forming mold 7 having a plurality of female housings 8 and as many male elements 9 arranged along corresponding longitudinal directions A, wherein the female housings 8 and the male elements 9 can be coupled together to define at least partially an interspace 10 for forming the strip 1.
  • the female housings 8, in practice, are intended to shape the outer surfaces of the strip 1, while the male elements 9 are intended to shape the inner surfaces thereof.

  • the strips 1 obtained by means of the procedure according to the invention have five vials 2 each, which are made by means of five female housings 8 and five male elements 9; it is easy to appreciate however that by changing the number of female housings 8 and of the male elements 9 strips 1 can be obtained with a different number of vials 2.
  • the procedure according to the invention comprises the following steps:
  • the step consisting in modifying the shape of the interspace 10 occurs at least at the first ends 4a of the vials 2; in this respect, it should be noticed that, in the present treatise, when it is said that the interspace 10 is modified at the first ends 4a it means that the shape is modified of that part of interspace 10 which is intended to shape the strips 1 in the proximity of the first ends 4a of the vials 2.
  • the containment bodies 4 of the vials 2 are made of the first material to form a single monolithic body wherein the containment bodies 4 are joined together along the weakened-section connection lines 3, while the dispensing mouths 5 of the vials 2, i.e., those parts of the vials 2 which define the dispensing mouths 5, are made of the second material.
  • the first material preferably consists of a plastic material, e.g., a polymer material, such as polyethylene, polypropylene, etc.
  • the second material consists e.g. of a plastic material, e.g., a polymer material different from the first material, or of rubber.

  • the female housings 8 of the first group 13 are substantially identical to the female housings 8 of the second group 15, while the auxiliary male bodies 12 of the first group 14 have a different shape with respect to the auxiliary male bodies 12 of the second group 16.
  • the auxiliary male bodies 12 of the first group 14 in fact, have a first face 17 turned towards the male elements 9 which is protruding overhanging towards the male elements themselves; the auxiliary male bodies 12 of the second group 16, on the contrary, have a second face 18 turned towards the male elements 9 which is flat.
  • Figure 2 shows the forming mold 7 in a closed configuration without the first material, the second material and the strip of semi-finished vials 11 inside it; in this figure, we can see that the shape of the interspace 10 delimited by the female housings 8, the male elements 9 and the auxiliary male bodies 12 in the first station 13, 14 is different from that of the second station 15, 16.
