Closure with built-in storing compartment

Abstract

The present invention is a closure (1) suitable for closing a container containing a first product, said closure being an assembly of less than four independent pieces, and having external side walls (3), a top wall (4), and an internal skirt (5) extending downwardly inside the side walls (3) from the top wall (4), characterized in that : (i) the internal skirt (5) comprises an opening disposed in the top wall (4) of the closure, said opening being closed by a membrane, so as to define at least one compartment to store a second product separately from said first product, and (ii) the membrane (11) closing the top wall opening is made of an oxygen-barrier material, so that said compartment (6) is free of oxygen contamination from ambient air when said closure (1) is screwed onto the neck (2) of said container.

Description

Technical field [0001] The invention relates to a closure with a built-in storage compartment. More specifically, the present invention relates to an enclosure including a storage compartment with oxygen barrier properties. Background technique [0002] For a long time, closures for containers have been developed that allow a first ingredient or ingredient mixture to be contained in the main container while another ingredient or ingredient mixture is contained in a smaller container located in the closure. Such a packaging system allows ingredients to be stored in the same package for a longer period of time, otherwise these ingredients will react or deteriorate when they come into contact before the expiration of the storage period. In this case, just before consumption, the consumer opens the closed container and mixes the product contained in the closed container with the product in the main container. [0003] Such packaging closure systems have been described in various prio...

Problems solved by technology

In addition, the sanitation of the closure before placing it on the bottle is technically difficult to achieve, although this is required

Last (but not least), the fact that the closures need to be filled separately from the bottle closing step requires an inventory of pre-filled closures, since it is difficult to plan for bottle production forecasts

Inventory of prefilled closures is not necessarily adequate, sometimes resulting in waste of prefilled closures when the number of bottles to be capped is not as high as the established closure inventory

After determining the price of the product filled into the closure, this waste is highly undesirable for economical reasons
