Single dose package with applicator

Abstract

A single-dose package designed to allow the application by pressure of a product using the package.

1 . A single-dose package for the application by pressure of a product on an application surface, comprising:
 a semi-rigid structural sheet;   an opening system comprising a weakness to allow a user to cause a movement of the package from a closed condition to an open condition;   a flexible covering sheet fixed on the structural sheet in such a way as to form a space between the layers, the space being closed in the closed condition of the package;   a system for application of the product which, in the closed condition, is situated in the space;   
       wherein:
 the application system comprises an applicator which, at least in the closed condition, keeps the product in position in the space; 
 the application system and the opening system are configured in such a way that, in the open condition, at least a part of the applicator protrudes outside the space, so as to allow a user to apply the product by moving the at least one part of the applicator in contact with the application surface. 
 
     
     
         2 . The package according to  claim 1 , wherein:
 the weakness comprises a line of weakness configured in such a way that the movement of the package occurs around the line of weakness;   the line of weakness is situated on the structural sheet and defines, on the structural sheet, a tab, the at least a part of the applicator being located, in the closed condition of the package, on the tab.   
     
     
         3 . The package according to  claim 2 , wherein the applicator comprises a support and an absorbent element, in which the product is absorbed, the absorbent element being supported by the support, the application system and the opening system being configured so that:
 the closed condition of the package corresponds to a first position of the absorbent element relative to the space, in which the absorbent element is inside the space;   the open condition of the package corresponds to a second position of the absorbent element relative to the space, in which the absorbent element is outside the space;   the absorbent element is fixed on the support in such a way that, in the open condition of the package, a user can rub the absorbent element on the surface, manoeuvring the support, so as to apply the product on the application surface.   
     
     
         4 . The package according to  claim 3 , wherein the application system and the opening system are configured in such a way that, in the open condition, the absorbent element faces directly towards the outside of the package. 
     
     
         5 . The package according to  claim 4 , wherein:
 the line of weakness divides the structural sheet into a first area and a second area;   the first area comprises a main portion and the tab;   the tab, in the closed condition of the package, protrudes from the first area towards the second area.   
     
     
         6 . The package according to  claim 5 , wherein the support, at least in the closed condition, extends astride the tab and the main portion, in such a way as to define a first portion and a second portion of the support, the first portion of the support being located on the tab and the absorbent element being fixed on the first portion of the support  51 , the second portion of the support being located on the main portion. 
     
     
         7 . The package according to  claim 6 , wherein the application system comprises a constraint by means of which the support is connected to the structural sheet, the constraint extending only on a transition area between the first portion and the second portion, in such a way that the end portions of the first portion and second portion are free. 
     
     
         8 . The package according to  claim 7 , wherein the constraint is a welding line interposed between the first portion and second portion. 
     
     
         9 . The package according to  claim 5 , wherein:
 the line of weakness comprises a first lateral sector and a second lateral sector;   the line of weakness comprises a central sector interposed between the lateral sectors;   the lateral sectors delimit the main portion of the first area, and the central sector describes a recess relative to the lateral sectors, in such a way that the central sector delimits and defines the tab.   
     
     
         10 . The package according to  claim 9 , wherein the opening system is configured so that, following the movement of the package, the central sector breaks in such a way as to separate completely the tab relative to the second area of the structural sheet. 
     
     
         11 . The package according to  claim 3 , wherein the support and the structural sheet are fixed to one another on respective faces both made of polypropylene or polyethylene or polyactic acid.
