Sample product dispenser

Abstract

The invention concerns a device for dispensing at least one dose of fluid product sample, comprising: a device for dispensing said dose of product contained in a reservoir, two thin walls enclosing said device, each of said walls having an outer surface forming a support for being fixed on a flat document, or constituting an advertising medium, and a member for fixing the thin walls on the dispensing device. The member has a thickness not less than that of the dispensing device, such that said member prevents any direct pressure on said device. The member also has a generally flattened shape having a lateral surface with two opposite main parts, said lateral surface being inscribed substantially entirely between two parallel planes located proximate each other.

1 . A dispenser for at least one dose of a fluid product sample, comprising:
 a device for dispensing the said dose of product contained in a reservoir;   two thin walls enclosing the said device, each of the walls having an external face forming a support for fixing to a flat document or constituting an advertising medium;   a member for fixing the thin walls on the dispensing device, the member forming a protective element for the dispensing device while having a thickness greater than or equal to that of the dispensing device, so that the member prevents any direct pressure on the device, the member also having a general flattened shape having a lateral face having two opposite main parts, this lateral face fitting substantially entirely between two parallel planes (P 1 , P 2 ) situated close to each other, the two opposite main parts being situated in or in the immediate vicinity of the two planes so that the two main parts form support surfaces providing the distribution of pressure forces in directions perpendicular to the planes and friction forces in directions parallel to the planes, in order to prevent degradation of the dispensing device.   
   
   
       2 . A dispenser according to  claim 1 , wherein the member comprises two substantially planar support surfaces, facing each other and substantially parallel to each other. 
   
   
       3 . A dispenser according to  claim 1 , wherein the fixing member has flats constituting a set of support surfaces. 
   
   
       4 . A dispenser according to  claim 2 , wherein the thin walls are fixed to all the support surfaces of the fixing and protection member. 
   
   
       5 . A dispenser according to  claim 1 , wherein the fixing member is rigidly associated with the dispensing device. 
   
   
       6 . A dispenser according to  claim 1 , wherein the dispensing device comprises a pump, a pump body and a reservoir. 
   
   
       7 . A dispenser according to  claim 6 , wherein the pump body is fitted in a cylindrical bore produced in the fixing member. 
   
   
       8 . A dispenser according to  claim 6 , wherein the pump body has a diameter less than the thickness of the fixing member, preferentially around 3 mm. 
   
   
       9 . A dispenser according to  claim 6 , wherein the pump body is made in one piece with the fixing member. 
   
   
       10 . A dispenser according to  claim 1 , wherein the flexible thin walls are hermetic and secured to one another in the vicinity of their periphery sealingly. 
   
   
       11 . A dispenser according to  claim 10 , wherein the thin walls fixed together define the edges of a reservoir of the sample of liquid product. 
   
   
       12 . A dispenser according to  claim 1 , wherein the thin walls are flexible. 
   
   
       13 . A diffusion assembly comprising at least one dispenser according to  claim 1 , fixed to a substantially planar support. 
   
   
       14 . A fluid dispenser comprising:
 substantially flexible walls defining an enclosed and sealed fluid-reservoir, and an enclosed and sealed dispenser-cavity in a first condition;   a pump head located in the cavity in the first condition, the pump head being accessible for use when the walls are severed adjacent the cavity in a second condition; and   a conduit connecting the pump head to the reservoir;   the walls withstanding at least one tonne of pressure in at least one direction in the first condition, without bursting.   
   
   
       15 . The dispenser of  claim 14 , further comprising a protective member located at least partially between the cavity and the reservoir, the protective member having a transverse thickness greater than the pump head, the protective member including at least two opposite flat outer, transverse surfaces. 
   
   
       16 . The dispenser of  claim 14 , wherein the walls withstand a transverse load of about 2.5 tonnes for about six seconds without bursting and without damage to the pump head. 
   
   
       17 . The dispenser of  claim 14 , further comprising:
 a protective member coupled to the pump head;   at least one biasing member and the conduit being attached to the protective member as a single piece.   
   
   
       18 . A fluid dispensing assembly comprising:
 walls defining an enclosed and sealed fluid-reservoir, and an enclosed and sealed dispenser-cavity in a first condition;   a liquid located in the reservoir, the liquid taken from the group of: (a) a perfume, (b) a cosmetic, and (c) a pharmaceutical;   an advertising page having at least one of the walls at least temporarily attached thereto;   a pump head located in the cavity in the first condition, the pump head being accessible for use when a wall portion is opened in a second condition; and   a protective member coupled within the walls adjacent the pump head in at least the first condition, the protective member operably protecting the pump head from compression in at least one direction.   
   
   
       19 . The dispensing assembly of  claim 18 , wherein the protective member has a greater transverse dimension as compared to the pump head in the at least one direction, further comprising a conduit and a biasing member coupled to the protective member, the conduit extending into the reservoir. 
   
   
       20 . The dispensing assembly of  claim 18 , wherein the walls are flexible and the walls withstand a load in the at lest one direction of about 2.5 tonnes for about six seconds without bursting and without damage to the pump head.
