Definitions

  • the present invention relates to a refill system comprising:
  • Such a refill system is known, see for example US-2011/042944 .
  • a disadvantage thereof is that the contents of the refill container do not flow into the container in an automatic and leak-free manner via the mutually coupled connector parts. It is therefore usually the case that the refill system as a whole has to be shaken several times or has to be struck in order to stimulate an exchange of media, often liquids and air, and to allow the container to be filled from the refill container. Since the refill system is then not child-resistant or completely leak-free, dangerous situations arise, specifically in the case of aggressive media.
  • the refill system according to the invention has the features of claim 1.
  • An advantage of the refill system according to the invention is that after the mutual coupling of the connector parts A and B, said connector parts are fitted to one another in a leak-free manner and cannot be disconnected from one another.
  • a further advantage is that the connector part B may optionally already be fitted on the refill container upon purchase, which saves on a separate cap on the refill container.
  • the assembly A, B is coupled in a leak-free manner. It is only during the further screwing of the container onto the connector part A that the first and second seals present therein are lifted and the ventilation opening and the medium through-flow openings are freed.
  • the presence of the two types of openings which are separate from each other results in improved ventilation, as a result of which the medium from the refill container flows to the container in a direct and unobstructed manner in order there to be able to mix in a satisfactory manner with the possibly already present medium and/or added water.
  • the refill system according to the invention only necessitates the purchase of the refill container, which is a lot smaller in practice, instead of it being necessary to buy a container which is often larger and which has, for example, a closure cap. In this way, less material, in particular plastic, specifically for the manufacture of the refill container, is required, which additionally takes up less shelf space in the retail venue. In practice, a greater concentration of the medium in the smaller refill container ensures that there is a smaller transport volume and that there is less contaminating material from which the container and the refill container are generally manufactured.
  • one embodiment of the refill system has the feature that one or both of the aforementioned inner regions has/have a circular cross section.
  • Circular cross sections lead both to a good seal and to a very good through-flow of medium and air.
  • a possible central positioning of one or both of the aforementioned types of openings in further embodiments improves the through-flow profile, the through-flow volumes and the through-flow rates of the media even more.
  • a further embodiment of the refill system has the feature that the first seal is provided at the end of a funnel shape which narrows in the axial direction from that end face of the connector part which faces towards the container.
  • the clear spatial separation of the two types of openings from one another here is an advantage that leads to a situation whereby the air flowing back from the container to the refill container and the medium flowing the other way, downward, on account of the exerted gravitational force similarly flow separately from one another.
  • Figures 1 and 2 show a refill system 1 comprising a container 4 for a frequently liquid-containing medium, said container being provided with a neck having an opening 2 with a screw thread 3 thereon. Furthermore, the system 1 comprises a refill container 7 specifically for powdered and/or liquid-containing media, said refill container being provided with an opening 5 having, in this case, a screw thread 6, and an assembly of connector parts A, B which can be attached between the container 4 and the refill container 7 in the longitudinal direction with respect to each other. Said assembly is composed of the connector part A which can be attached to the opening 2 of the container 4 and the connector part B attached to the opening 5 of the refill container 7.
  • Figure 3 and detail 3A show, in a manner which will be explained in more detail, how the connector parts A and B are designed to bring about an exchange of media and air between the refill container 7 and the container 4 in a coupled state.
  • the connector part A is delimited by end faces 8-1, 8-2 located opposite each other as seen in the axial direction and comprises a circumferential cavity 9 which extends axially from the end face 8-1 facing towards the container 4.
  • the cavity 9 contains an internal screw thread 10 for screwing in the screw thread 3 of the container 4, which cavity 9 itself is axially delimited by a recessed stop edge 11.
  • Medium through-flow openings 12 are provided in an inner region 13 separate from the circumferential cavity 9, wherein a ventilation opening 14 is provided in the inner region 13 at an axial spacing from the end face 8-1.
  • the connector part B is to this end axially delimited by end faces 15-1, 15-2 located opposite each other and comprises a circumferential cavity 16 which extends from the end face 15-2 facing towards the refill container 7 and in which an internal screw thread 17 is located for, in this case, screwing in the screw thread 6 of the refill container 7.
  • Medium through-flow openings 18 are provided in an inner region 19 which is separate from the circumferential cavity 16 and in which a first seal 20 is provided which is designed to seal the ventilation opening 14 in the connector part A when the connector parts A and B are being coupled, and wherein, at the location of that end face 15-1 of the connector part B which faces towards the connector part A, a second seal 21 is provided which is designed to seal the medium through-flow openings 12 in the connector part A when the connector parts A and B are being coupled.
  • One or more slots 22 are provided in the stop edge 11 of the connector part A.
  • the combination figure 7 shows four in this embodiment.
  • the connector part B is provided with ribs 23 which fit into the slots 22, the ribs 23 sliding over the stop edge 11 towards the slots 22 during the coupling, and the mutual twisting, of the connector parts A and B in order to subsequently protrude through the slots 22.
  • a click-fit edge 24-1 is located on the outer circumference of the connector part B and a corresponding click-fit edge 24-2 is located on the inner circumference of the connector part A, said click-fit edges being snapped over each other in the detail of Figure 3A .
  • the parts A and B are connected to one another in an inseparable manner ex works by way of the click-fit members 24-1 and 24-2 which engage in one another.
  • the click-fit edge angle ⁇ shown herein plays an important role in the case of the force which, based on the pitch of the screw thread 3 on the neck of the container 4 which can be twisted, as shown in Figure 6 , has to be exerted on the click-fit edges in order to allow said click-fit edges to be click-fitted forward or back with a certain force and audibility.
  • the connected parts A and B may, by way of part B, possibly also be screwed to the refill container 7 in an inseparable manner ex works by means of further click-fit members.
  • the connector part B and the opening 5 of the refill container 7 are thus provided, in a manner not shown and already known per se, with such click-fit members which engage in one another.
  • the intended child safety is specifically achieved because, in the coupled state of the refill system 1, the parts A and B are connected to one another in an inseparable manner ex works by way of the click-fit members 24-1 and 24-2 which engage in one another.
  • a child will not be able to rotate the refill container 7 together with the two connector parts A and B on the container 4, let alone be able to subsequently rotate the refill container 7 together with the two connector parts A and B further on the container 4 such that the ribs 23 of the connector part B which protrude through the slots 22 in the stop edge 11 of the connector part A are pushed backwards into the slots 22 to the extent that the click-fit edges 24-1 and 24-2 snap over each other.
  • This is independent of whether or not the additional click-fit edges 24-3 are present. From a child safety standpoint, these may also be omitted, but should advantageously be included in order to prevent the two connector parts A and B from coming completely loose from one another after the click-fit edges 24-1 and 24-2 have been forcedly snapped over each other.
  • the aforementioned inner regions 13 and/or 19 have a circular cross section.
  • the inner regions 13, 19 shown are here divided into segments which are delimited and reinforced by reinforcing ribs 26.
  • both the ventilation opening 14 and its first seal 20 lie centrally in the inner regions 13, 19 and/or the medium through-flow openings 12 and its second seal 21 lie centrally in the inner regions 13, 19.
  • the first seal 20 is provided at the end of a funnel-shaped member 27 which narrows in the axial direction from that end face 8-1 of the connector part A which faces towards the container 4. This has the benefit of accelerating the exchange of the respective media.
  • stops 28 are provided on the stop edge 11 of the connector part A which prevent the twisting of the ribs 23 over the upper side of the aforementioned stop edge 11 and, in that state, position the ribs 23 in front of the slots 22, through which said ribs pass upon further twisting. This results in improved positioning and centring.
  • the refill system 1 and its connector parts 7, A and/or B are preferably manufactured from one and the same plastic, and can in this case advantageously be manufactured as individual unitary parts.
