Definitions

  • the present invention relates to a container cap, particularly for vials for products to be mixed at the time of use, as well as to a vial for products to be mixed at the time of use comprising such a container cap.
  • Vials for products to be mixed at the time of use comprising a container cap, i.e., a cap comprising a reservoir that contains a solid, powdered product, are currently known.
  • This container cap closes the opening of a container containing a liquid product intended to be mixed with the solid powdered product.
  • the container cap comprises a cutter configured to break a breakable bottom with which the reservoir containing the solid product to be mixed with the liquid product is provided.
  • a cutter is generally defined by a tubular body which is axially movable inside the reservoir itself, and has a sharp end.
  • the container cap further comprises a plug associated with the opening of the vial container.
  • This plug may be internally threaded, so as to be associated with a corresponding thread present on the opening of the container, or unthreaded. In the latter case, the plug is fixed to the opening of the container by means of an undercut which engages under a band mouth to hold the plug thereon. This plug is removable at the time of use by acting on appropriate tabs and pre-breakage areas.
  • the cutter is in turn associated with this plug, so that the screwing of this plug onto the opening of the vial container causes an axial advancement of the cutter inside the reservoir and the breaking of the breakable bottom of the reservoir itself.
  • the solid product contained inside the reservoir can fall by gravity into the container to be mixed with the liquid product.
  • the subsequent unscrewing of the plug allows the container cap to be removed as a whole (plug, reservoir and cutter) to access the mixture of the two products thus obtained.
  • a drawback of the solid, powdered products, stored inside the reservoir of the container caps of the known type described above is linked to the fact that these solid products are particularly sensitive to humidity, and to any additional gases that are released by the liquid product present in the vial.
  • a first problem concerns the deterioration of the chemical and/or physical properties of the solid, powdered product due to the presence of humidity.
  • a second problem concerns the risk that the solid, powdered product will agglomerate and adhere to the walls of the reservoir and/or of the cutter, making the emptying of the reservoir into the container of the vial difficult and partial.
  • solutions which provide for coating with a layer of adsorbent and/or hygroscope material the inner surface of the cutter, i.e. the surface thereof that faces onto the inner chamber of the reservoir, where the solid product is contained, or solutions that involve making the cutter itself, in whole or in part, with adsorbent and/or hygroscopic material, or solutions that envisage for providing the cutter with elements made with adsorbent and/or hygroscopic material, protruding inside the internal chamber of the reservoir itself.
  • the main task of the present invention consists in realising a container cap, particularly for vials for products to be mixed at the time of use, which avoids the drawbacks of the prior art and enables to ensure an optimal absorption of humidity that might deteriorate the solid, powdered product contained in the container cap itself.
  • an object of the invention consists in realising a container cap which is capable of giving the greatest guarantees of reliability and safety in use.
  • Another object of the invention consists in realising a container cap which is easy to realise and economically competitive when compared to the prior art.
  • the container cap particularly for vials for products to be mixed at the time of use, is globally indicated with the reference number 1.
  • Such a cap is adapted to close an opening 101 of a container 103 of a vial 100, wherein said container 103 is intended to contain a first product, preferably in liquid form.
  • the container cap 1 comprises a reservoir 3, defined by at least one lateral wall 31 and a breakable bottom 33, and a cutter 5 comprising a tubular body 50 comprising in turn a first sharp axial end 52.
  • the cutter 5 is axially movable inside the reservoir 3, for example along the central axis A of the container cap 1 and of the bottle 100, so as to press, with its sharp end 52, the breakable bottom 33 of the reservoir 3, to break said breakable bottom 33 and open the chamber 4 towards the container 103 of the vial 100.
  • the second product in solid form, present, in use, in the reservoir 3, falls by gravity into the container 103 reaching the first product, in liquid form, and mixing with it.
  • At least a portion of the breakable bottom 33 of the reservoir 3 and/or at least a portion, bordering said breakable bottom 33, of an inner face of said at least one lateral wall 31 of the reservoir 3 comprises adsorbent and/or hygroscopic material 7, i.e., dehydrating material.
  • Such an adsorbent and/or hygroscopic material 7 is adapted to absorb gases and/or humidity from the surrounding environment.
  • reservoir 3 with circular cross-section, there is a single cylindrical lateral wall 31, whereas in the case of reservoir 3 with a polygonal cross-section, the lateral walls defining the reservoir 3 are equal in number to the sides of the polygon of the section.
  • the cylindrical reservoir 3 i.e., with single cylindrical lateral wall 31.
  • the reservoir 3 has adsorbent and/or hygroscopic material 7:
  • the inner face is the face of the lateral wall 31 and/or of the breakable bottom 33 turned towards the inner chamber 4 of the reservoir 3.
  • the fact of providing adsorbent and/or hygroscopic material 7 directly on the walls 31 or on the bottom 33 of the reservoir 3 allows to effectively intercept gases or humidity that may penetrate from outside, in the contact area between the lateral wall 31 of the reservoir 3 and the wall of the cutter 5, as this is a very critical area for the penetration of gases and humidity from the outside, as well as gases and humidity generated by the presence of the first product, in liquid form inside the container 103, which tends to penetrate through the walls 31 or the bottom 33 of the reservoir 3 itself, in any case before gases and humidity reach the second product, in solid form, present in the reservoir 3.
  • the portion of the inner face of the lateral wall 31 comprising the adsorbent and/or hygroscopic material 7 is located in proximity to the breakable bottom 33, i.e., so as to border it, and/or in correspondence with the breakable bottom 33, i.e., on the breakable bottom 33 itself.
  • this adsorbent and/or hygroscopic material 7 is located right in proximity to the breakable bottom 33.
  • this adsorbent and/or hygroscopic material 7 is located exactly in correspondence with the breakable bottom 33.
  • the adsorbent and/or hygroscopic material 7 is preferably located in the lower part of the reservoir 3, where the second product, of solid form, tends to accumulate by gravity.
  • the adsorbent and/or hygroscopic material 7 comprises a layer of adsorbent and/or hygroscopic material 7 applied to the inner face of the lateral wall 31 and/or of the breakable bottom 33 of the reservoir 3.
  • the adsorbent and/or hygroscopic material 7 can be made as one piece, for example by means of injection moulding techniques of polymeric materials additivated with substances capable of absorbing gases and/or humidity, and assembled in a manual or automated manner inside the reservoir 3 itself.
  • the adsorbent and/or hygroscopic material 7 may be an adsorbent and/or hygroscopic polymer.
  • At least a portion 70, 72, 73 of the adsorbent and/or hygroscopic material 7 present on the lateral wall 31 and/or on the breakable bottom 33 is adapted to come into direct contact with the second product, in solid form, intended to be contained inside the chamber 4.
  • the portion 72, 73 of adsorbent and/or hygroscopic material 7 present on the breakable bottom 33 is in direct contact with the second material present in the reservoir 3.
  • the sharp end 52 of the cutter 5 is defined by a portion of the tubular body 50 thereof cut along an inclined plane.
  • the sharp end 52 of the cutter 5 is configured so that a portion of the lateral wall 31 of the container 3 directly faces onto the chamber 4.
  • the presence of a portion 70 of adsorbent and/or hygroscopic material 7 right in correspondence with the lateral wall 31 of the reservoir 3 not covered by the tubular body 50 of the cutter 5 allows the second product to come into direct contact with said portion 70 of adsorbent and/or hygroscopic material 7.
  • the adsorbent and/or hygroscopic material 7 is distributed substantially over the entire surface of the inner face of the breakable bottom 33.
  • this first portion 71 and this second portion 73 of adsorbent and/or hygroscopic material 7 are mutually connected, in correspondence with the aforesaid weakening line 35, by means of a thinned portion 75 of adsorbent and/or hygroscopic material 7, i.e., a reduced volume portion.
  • the adsorbent and/or hygroscopic material 7 forms a kind of glass which internally covers the lateral wall 31 and the breakable bottom 33 of the reservoir 3, and which contains, in its inside, the second product, in solid form, of which the chemical and physical properties are to be preserved from humidity.
  • the aforesaid thinned portion 75 comprises a number of connecting bridges 76 that is greater than or equal to two, distributed substantially uniformly along the weakening line 35, i.e., along the perimeter circumference of the breakable bottom 33.
  • the connecting bridges 76 have, in plan, a transverse width approximately comprised between 3% to 15% of the length of the diameter of the breakable bottom 33.
  • the connecting bridges 76 allow on the one hand to ensure the presence of a continuity of adsorbent and/or hygroscopic material 7 between the portions 71 and 73 respectively placed on the lateral wall 31 and on the breakable bottom 33 of the reservoir 3, and on the other hand not to constitute reinforcing structures of the connection of the breakable bottom 33 to the lateral wall 31 of the reservoir 3, which might preclude or in any case make it difficult to break the breakable bottom 33 along the weakening line 35.
  • the present invention also concerns a vial 100 for products to be mixed at the time of use.
  • this vial 100 comprises a container 103 intended to contain a first product, in liquid form, and a container cap 1, as described above, adapted to close an opening 101 of this container 103.
  • the container cap 1 further comprises a plug 105 associated with the opening 101 of the container 103 of the vial 100 by means of a thread, or by means of a band.
  • this plug 105 is associated with the cutter 5 in such a way that screwing the plug 105 onto the opening 101 causes the axial displacement of the cutter 5 in order to break the breakable bottom 33 of the reservoir 3.
  • the protection of the solid product from humidity ensures that, as soon as the cutter 5 breaks and opens the breakable bottom 33 of the reservoir 3, all the content of the reservoir 3 fall by gravity into the container 103, without packing and sticking to the walls of the reservoir 3 and/or the cutter 5.
  • the container cap particularly for vials for products to be mixed at the time of use, according to the present invention, fulfils the task as well as the intended purpose as it prevents the formation of humidity inside the container containing the product in solid form, in powder, to be mixed with the product in liquid form in the vial.
  • Another advantage of the container cap, according to the invention consists in preventing the deterioration due to the humidity of the product in solid form.
  • a further advantage of the container cap, according to the invention consists in always guaranteeing the correct and complete emptying of the reservoir containing the product in solid form.
  • Yet another advantage of the invention consists in the fact that the application of adsorbent and/or hygroscopic material to the walls and/or to the bottom of the reservoir does not necessarily involve a reduction of the internal volumetric capacity of the reservoir itself, as instead occurs in the case in which such material is applied to the cutter.
  • the inner containment chamber of the second product is defined by the space comprised inside the cutter which space, according to the invention, does not undergo volume reductions due to the presence of the aforesaid adsorbent and/or hygroscopic material.
  • the container cap particularly for vials for products to be mixed at the time of use, as conceived herein is susceptible to numerous modifications and variations, all of which are part of the inventive concept as defined in the appended claims.
