Definitions

  • the invention relates to container means, particularly suitable for exhaling into an environment a volatile substance through a permeable wall .
  • Containers of a first type are known, arranged to receive volatile substances, for example deodorants for environments or insecticides, and comprising a transparent wall in plastic material, shaped in such a way as to define .a. cavity suitable for receiving the volatile substance.
  • This cavity is closed behind by a sheet material comprising a barrier layer coupled with a permeable layer.
  • the latter is turned towards the inside of the cavity in such a way as to come into contact with the volatile substance, whilst the barrier layer is arranged towards the outside of the container.
  • the transparent wall is connected to the barrier layer along a heat-sealed edge zone, that extends peripherally around the entire cavity.
  • a pickup region is also provided, by grasping which the user can exert a peeling action on the barrier layer to separate it from the permeable layer.
  • the latter remains adhering to the container and, owing to its permeability, enables the volatile substance to spread through the surrounding environment.
  • a portion of the heat-sealed edge zone is interposed between the cavity and the pickup region, which is thus totally separated from the cavity.
  • the pickup region is furthermore delimited by a weakening line, that affects both the barrier layer and the permeable layer. In this way, when the user separates by peeling the barrier layer from the permeable layer, the portion of the permeable layer originally arranged in the pickup region remains attached to the barrier layer removed from the container.
  • Containers of a second type consisting of two heat-formed shells joined together along a heat-sealed edge zone, a cavity being defined between the two shells that is suitable for being filled with liquid or viscous substances such as creams, shampoo or other products. From the cavity an exit conduit develops that is provided with an opening end communicating with the cavity and with a sealed end closed by a portion of the heat-sealed edge zone.
  • the open end and the sealed end of the outlet channel lie on opposite sides of a weakening line that extends transversely to the outlet channel, identifying, in a zone of the container opposite to the cavity, a pickup region arranged to be grasped by a user.
  • a weakening line that extends transversely to the outlet channel, identifying, in a zone of the container opposite to the cavity, a pickup region arranged to be grasped by a user.
  • the pickup region separates along the weakening line on the side of the container that comprises the cavity. This enables the cavity to communicate with the outside environment inasmuch as together with the pickup region a part of the outlet channel that comprises the sealed end is also removed from the container.
  • containers with a permeable wall are suitable for receiving volatile substances that have to be exhaled into a surrounding environment in a slow and gradual manner after changing to a gaseous state.
  • containers consisting of two heat-sealed shells are suitable for receiving running substances that at the moment of use have to exit rapidly from the container while remaining in the same physical state in which they were when they were contained in the cavity. For this reason, the containers consisting of two heat-sealed shells are not suitable for receiving inside themselves a volatile substance that has to be gradually exhaled into an environment . . . . . .
  • One object of the invention is to improve container means for volatile substances of the known type.
  • a further object of the invention is to provide container means for volatile substances the shape of which remains as stable as possible during use.
  • container means comprising cavity means at least partially delimited by permeable wall means through which, in an opening configuration, a volatile substance can exit from said cavity means, characterized in that passage means, shaped and having dimensions such as to enable the entry of air into said cavity means in said opening configuration, is associated with said cavity means .
  • the pressure decrease in the cavity means due to the exit of the volatile substance through the permeable wall means is substantially offset by the air that enters the cavity means through the passage means. Deformation of the permeable wall means due to the pressure decrease is thus significantly reduced and the container means according to the invention maintains a pleasing appearance even during use and furthermore enables the product to exit completely.
  • Figure 1 is a schematic front view of a container according to the invention, in a closure configuration
  • Figure 2 is a section taken along the plane II-II in Figure 1 / Figure 3 is a section like the one in Figure 2, showing a peeling phase of a barrier layer with which the container in Figure 1 is initially provided;
  • Figure 4 is a view like the one in Figure 1, showing the container according to the invention in an opening configuration.
  • Figures 1 and 2 show a container 1, particularly suitable for containing a volatile substance 2, for example a deodorant or an insecticide, intended to be exhaled into an environment.
  • the container 1 comprises a cavity 3, wherein the volatile substance 2 is received, the cavity 3 being delimited by a first wall 4 and by a second wall 5, connected together along an edge zone 6.
  • the first wall 4 is provided with substantially flat geometry and comprises a permeable layer 7 facing the cavity 3 and coupled in a peelable manner with a barrier layer 8 turned towards the outside of the container 1.
  • the permeable layer 7 has permeability properties such as to let the molecules of the volatile substance 2 pass from the cavity 3 to the outside of the container 1 and can for example be made of polyethylene (PE) .
  • PE polyethylene
  • the .barrier. -.layer .8 on the other...hand is... substantially impermeable to the volatile substance 2 and can for example be made of aluminium.
  • the second wall 5 comprises a layer of plastic material that has been formed, for example by heat-forming, in such a way as to obtain the walls that delimit the cavity 3.
  • the second wall 5 can be made of transparent polyethylene terephthalate (PET) .
  • the second wall 5 and the permeable layer 7 are heat-sealable, so as to enable the first wall 4 to be connected to the second wall 5 along the edge zone 6 by heat-sealing.
  • a conduit 9 is furthermore provided, obtained on the second wall 5 together with the cavity 3 by heat-sealing.
  • the conduit 9 is provided with an open end 10 ending inside the cavity 3 and with a closed end 11, around which the first wall 4 and the second wall 5 are united to each other along the edge zone 6.
  • Opening indicator means is also provided comprising a weakening line 12 that extends transversely to the conduit 9 along the edge zone 6.
  • the weakening line 12 may for example comprise a perforation or incision line obtained on the second wall 5 and possibly on the permeable layer 7.
  • the weakening line 12 identifies on the container 1 a greater region 13 in which the cavity 3 is obtained and a pickup region 14 that the user can use to access the volatile substance 2.
  • the closed end 11 of the conduit 9 is arranged in the pickup region 1.4, whilst the open end- 10 is arranged .in the greater region 13.
  • the pickup region 14 In order to use the container 1, the pickup region 14 must be grasped and a torsion action or a flexure action in relation to the greater region 13 must be performed thereupon. In this way the portions of the second wall 5 and of the permeable layer 7 arranged in the pickup region 14 are detached along the weakening line 12 from the further portions of the second wall 5 and of the permeable layer 7 arranged in the greater region 13.
  • the pickup region 14 remains connected to the greater region 13 by means of the barrier layer 8 that is still whole. At this point, as shown in Figure 3, grasping the pickup region 14 it is possible to remove by peeling the barrier layer 8 from the permeable layer 7, which stays anchored to the second wall 5 along the edge zone 6.
  • the volatile substance 2 can now spread into the surrounding environment by crossing the permeable layer 7 that is no longer protected by the barrier layer 8.
  • the container 1 can furthermore now be heated, for example by inserting one of its bottom portions into a heating device, in order to increase the speed of spreading of the volatile substance 2 in the environment.
  • the closed end 11 of the conduit 9 is removed from the container 1 and the conduit 9 is made to communicate with the surrounding environment.
  • The. conduit .9 .thus allows., the. air coming, .from,.the surrounding environment to enter the cavity 3 as the volatile substance 2 exits through the permeable layer 7.
  • the pressure in the cavity 3 is kept substantially constant at a value that is approximately the same as atmospheric pressure, which enables the permeable layer 7 to be kept in a substantially undeformed flat configuration.
  • the conduit 9 thus acts as a passage means that enables air coming from the surrounding environment to enter the cavity 3.
  • the conduit 9 performs a function that has nothing in common with the function of the outlet conduit provided in the known containers formed of two facing shells.
  • the outlet conduit in fact served only to deliver the contents outside the container, thus performing a function that in the container 1 according to the invention is assigned to the permeable layer 7.
  • No passage means for the entry of the air is provided in the known containers formed by two facing shells, in which avoiding the deformation of the container during use has no importance.
  • known containers are intentionally crushed to ensure that their contents exits more rapidly and effectively from the cavity.
