Definitions

  • the present invention relates to a dispensing device for fluid substances.
  • Containers with a movable base are known, usually associated with a hermetic pump.
  • hermetic pump The characteristic feature of a hermetic pump is to dispense the product while not enabling air to enter the container interior.
  • hermetic pumps do not present venting passages. The result is that the container is put under vacuum at each dispensing operation. This causes the base to rise, with consequent reduction in the volume dedicated to housing the fluid to be dispensed, which gradually decreases after each dispensing operation.
  • a drawback of these types of devices is that when they have been filled with fluid for dispensing and then closed, air can remain in the container. This air can cause dispensing discontinuities.
  • a further drawback deriving from the presence of air in the container can be the possible incompatibility of air with the product contained in the device.
  • a possible example is creams which can dry out or other products which can alter on contact with air.
  • An object of the present invention is to simplify the operations related to the closure of movable base-type hermetic devices by making them less complex, less costly, and quicker.
  • the device 1 comprises a container 2 presenting a movable base 3 sealedly slidable therewithin.
  • An air passage 4 is present on the container base, enabling air to enter the region 5 below the base.
  • the device 1 also presents a ring cap 6 to which a manually operable hermetic pump is snap-connected.
  • the hermetic pump is of conventional type and will not be further described.
  • the pump is sealedly fixed to the ring cap 6 in totally conventional manner.
  • the ring cap/pump unit forms a closure element for the container 2.
  • the container 2 is snap-inserted into a casing 8 to which it is also fixed by means of the ring cap 6.
  • the ring cap 6 presents a recess 6A which snap-cooperates with an undercut on an annular tooth 8A provided on the casing 8.
  • the container 2 has a conical surface 2A which abuts against a corner 8b of the casing 8.
  • a flange 9A of a compression element 9 rests on the top of the container 2; when the container is closed the flange is compressed between a step 6C of the ring cap and the container itself, and hence remains locked.
  • a first cylindrical wall 9B extends from the flange 9A of the compression element 9 and is connected by a step 9C to a second cylindrical wall 9E which presents on its outer surface a projecting rim 10 acting as a seal element cooperating with the inner surface of the container 2.
  • a conical wall 11 extends from the second wall 9E to connect said wall via a deformable portion 12 to a discoidal portion 13 from which a frusto-conical surface 14 diverging towards the container interior extends.
  • the deformable portion has a smaller thickness than the rest of the compression element 9, which hence enables it to deform such as to pre-load the fluid inside the container.
  • the compression element 9 presents a unidirectional valve element which enables the air present above the fluid to be expelled during container closure.
  • deformable portion 12 which essentially has to deform to exert a pressure on the fluid inserted in the container, such as to facilitate expulsion of any air present therein.
  • FIGs 4 and 5 show for example other embodiments of the compression element, which are indicated therein by the reference numerals 90, 91.
  • the deformable portion 120 is formed as an outward swelling of the wall, which is only slightly thinner than the rest of the element wall. This improves the yieldability of the deformable portion which, given its shape, tends to "yield" before the other portions.
  • the illustrated compression element 91 comprises an outward swelling as in the previous embodiment. However, in this case, at the swelling 121 a greater thinning of the wall can be noted, to the certain advantage of deformation.
  • the deformable portion could be of bellows type, or a sufficiently elastic material could be chosen for making the compression element which would make the provision of a region dedicated to deformation superfluous. In that case, the overall elastic element would then deform at several points, to compress the fluid to the desired extent.
  • the valve element 15 can be formed in various ways obvious to the expert of the art, however in the present embodiment it is formed as an elastically deformable interface surface provided at the top of the frusto-conical portion, which is mounted about the cup-shaped body of the pump.
  • the frusto-conical portion 14 is mounted about a portion of the cup-shaped body of greatest radius, i.e. about that region of the cup-shaped body within which the stem slides. This enables the seal between the compression element and pump to be formed along a major diameter, so best utilizing the elastic properties of the constituent material of the compression element.
  • this latter is made by injection moulding a plastic material, such as PP, or PE, or thermoplastic filled with rubber, or elastomers.
  • the unit formed by the compression element and the pump bottom has a shape substantially complementary to that of the movable base, in order to be able to maximize the product quantity dispensed by reducing to a minimum the spaces between the base and the pump/compression element.
  • the compression element seals against the container 2, while a snap connection is provided between the casing 8 and the container by means of a tooth 2A which engages in an undercut provided in the casing 8.
  • Air passages 16 are provided In that portion in which the snap connection takes place, to feed the region 5 present below the movable base.
  • the air present in the interspace 22 between the pump body and the compression element begins to undergo compression both by the lowering of the closure element and by the consequent raising of the fluid within the container.
  • the surface of the elastically deformable interface of the compression element 9 deforms to open a passage 23 grazing the pump surface, enabling the residual air above the fluid to escape.
  • the elastically deformable interspace elastically returns to seal against the cup-shaped body.
  • the deformable portion enables the fluid contained in the container interior to be slightly precompressed, so minimizing any air quantity trapped within it.
  • the movable base container can be replaced by a container housing a deformable/collapsible bag.
