Dosing cap for a flexible bottle package, and a flexible bottle package provided with a dosing cap

Abstract

The present invention relates to a dosing cap for flexible flask or bottle packages, which is configured from a single piece and comprises a restrictor provided with means configured for enabling interruption of the product flow through its structure. The benefits achieved by the dosing cap of the present invention are related to the low production cost of this cap and to the low environmental impact generated during its manufacture and after the disposal thereof in the environment.

1 . A dosing cap for flexible bottle packages, comprising a restrictor provided with means configured for enabling interruption of the product flow through its structure, which is configured in a single piece. 
     
     
         2 . The dosing cap according to  claim 1 , wherein the restrictor comprises at least one restriction bore, the cross-sectional area of said restriction bore being calculated according to the viscosity of the fluid contained in the flexible flask, and the number of restriction bores comprised by the restrictor being compatible with the user's need to use said bottle. 
     
     
         3 . The dosing cap according to  claim 2 , wherein the cross-sectional area of the restriction bore is calculated so as to prevent passage of fluid through this structure, by exclusive action of the gravitational force on the fluid and so as to enable passage of the fluid by squeezing said bottle. 
     
     
         4 . The dosing cap according to  claim 1 , characterized by being injected by a single thermoplastic injection process. 
     
     
         5 . The dosing cap according to  claim 2 , wherein the thermoplastic injection process employed to manufacture it makes use of a single thermoplastic resin. 
     
     
         6 . The dosing cap according to  claim 1 , wherein the restrictor comprises four restriction bores positioned in radial arrangement around the restrictor, the cross-sectional area of each of these restriction bores ranging from 0.5 to 2 mm 2 . 
     
     
         7 . The dosing cap according to  claim 1 , characterized by being configured for use in food-condiment bottles. 
     
     
         8 . The dosing cap according to  claim 6 , characterized by being configured for use on ketchup, mustard and mayonnaise bottles. 
     
     
         9 . The dosing cap according to  claim 6 , characterized by being configured for use on personal hygiene and cleaning bottles. 
     
     
         10 . A flexible bottle package comprising the dosing cap as defined in  claim 1 .
