Closure for Dispensing Fragrance from the Closure

Abstract

A closure ( 2 ) for a container ( 3 ), the closure ( 2 ) being engageable with a container ( 3 ) to close the container ( 3 ) and/or having a first part engageable with a second part to close a container ( 3 ), wherein the closure ( 2 ) has an orifice ( 11 ) and has a source of fragrance ( 8 ), and includes a chamber ( 9 ), or, when the first part is engaged with the second part, forms a chamber ( 9 ), the chamber ( 9 ) containing the source of the fragrance ( 8 ), the closure ( 2 ) being arranged such that, when used to close a container ( 3 ), the chamber ( 9 ) is separated from an internal space of the container ( 3 ) and vented to the surroundings of the container ( 3 ) by the orifice ( 11 ), and compression applied to the chamber ( 9 ) causes a puff of the fragrance to be emitted from the chamber ( 9 ) through the orifice ( 11 ) into the surroundings of the container ( 3 ).

1 . A closure for a container, the closure being engageable with a container to close the container and/or having a first part engageable with a second part to close a container, wherein the closure has an orifice and, in use, has a source of fragrance, and includes a chamber, or, when the first part is engaged with the second part, forms a chamber, the chamber, in use, containing the source of the fragrance, the closure being arranged such that, when used to close a container, the chamber is separated from an internal space of the container and vented to the surroundings of the container by the orifice, and, in use, compression applied to the chamber causes a puff of the fragrance to be emitted from the chamber through the orifice into the surroundings of the container. 
   
   
       2 . A closure according to  claim 1 , wherein the closure is provided with a screw threaded portion for engagement with a corresponding screw threaded portion of a container. 
   
   
       3 . A closure according to  claim 2 , wherein the closure is a screw cap comprising a first wall, which, when the screw cap is used to close a container, separates the chamber from an internal space of the container, and a second wall in which the orifice is formed and which, but for the orifice, separates the chamber from the surroundings of the screw cap. 
   
   
       4 . A closure according to  claim 3 , wherein the first wall is flexible, such that when the closure is used to close a container, and the container is squeezed to increase an internal pressure within the container, the increased internal pressure results in compression of the flexible first wall and consequently compression of the chamber and emission of a puff of the fragrance from the chamber through the orifice into the surroundings of the container. 
   
   
       5 . A closure according to  claim 3 , wherein the second wall is flexible and accessible to be squeezed, such that squeezing of the closure results in compression of the flexible second wall and consequently compression of the chamber and emission of a puff of the fragrance from the chamber through the orifice into the surroundings of the closure. 
   
   
       6 . A closure according to  claim 1 , wherein the closure is a flip-top lid assembly comprising a nozzle through which, when the assembly is attached to a container, a consumable product contained in the container can be dispensed, and a flip-top lid engageable with the nozzle to close the nozzle, the nozzle forming a first wall, which, when the flip-top lid is engaged with the nozzle, separates the chamber from an internal space of the container, and the flip-top lid forming a second wall in which the orifice is formed and which, but for the orifice, separates the chamber from the surroundings of the flip-top lid assembly. 
   
   
       7 . A closure according to  claim 3 , wherein the closure has a source of fragrance and the first wall is permeable by the fragrance of the source of fragrance. 
   
   
       8 . A closure according to  claim 6 , wherein the flip-top lid is formed with a resiliently deformable blister such that compression of the blister results in compression of the chamber and emission of a puff of the fragrance from the chamber through the orifice into the surroundings of the closure. 
   
   
       9 . Packaging for a consumable product, the packaging comprising a container and a closure for the container, the closure being engageable with the container to close the container and/or having a first part engageable with a second part to close the container, wherein the closure has an orifice and, in use, has a source of fragrance, and includes a chamber, or, when the first part is engaged with the second part, forms a chamber, the chamber, in use, containing the source of the fragrance, the closure being arranged such that, when used to close the container, the chamber is separated from an internal space of the container and vented to the surroundings of the container by the orifice, and, in use, compression applied to the chamber causes a puff of the fragrance to be emitted from the chamber through the orifice into the surroundings of the container. 
   
   
       10 . A consumer product comprising a container having an internal space holding a consumable product of the consumer product, the container having an opening for dispensing the consumable product from the container and a closure which closes the opening, the closure being engageable with the container to close the opening and/or having a first part engageable with a second part to close the opening, wherein the closure has an orifice and a source of fragrance, and includes a chamber, or, when the first part is engaged with the second part, forms a chamber, the chamber containing the source of the fragrance, the closure being arranged such that, when used to close the opening, the chamber is separated from an internal space of the container and vented to the surroundings of the container by the orifice, and compression applied to the chamber causes a puff of the fragrance to be emitted from the chamber through the orifice into the surroundings of the container. 
   
   
       11 . A method of dispensing a fragrance from a consumer product having a container with an internal space holding an active substance of the product and with a chamber holding the fragrance, the method comprising squeezing the product and consequently causing a puff of fragrance to be emitted without the emission of any active substance from the internal space. 
   
   
       12 . A closure according to  claim 2 , wherein the closure is a flip-top lid assembly comprising a nozzle through which, when the assembly is attached to a container, a consumable product contained in the container can be dispensed, and a flip-top lid engageable with the nozzle to close the nozzle, the nozzle forming a first wall, which, when the flip-top lid is engaged with the nozzle, separates the chamber from an internal space of the container, and the flip-top lid forming a second wall in which the orifice is formed and which, but for the orifice, separates the chamber from the surroundings of the flip-top lid assembly. 
   
   
       13 . A closure according to  claim 4 , wherein the closure has a source of fragrance and the first wall is permeable by the fragrance of the source of fragrance. 
   
   
       14 . A closure according to  claim 5 , wherein the closure has a source of fragrance and the first wall is permeable by the fragrance of the source of fragrance. 
   
   
       15 . A closure according to  claim 6 , wherein the closure has a source of fragrance and the first wall is permeable by the fragrance of the source of fragrance. 
   
   
       16 . A closure according to  claim 7 , wherein the flip-top lid is formed with a resiliently deformable blister such that compression of the blister results in compression of the chamber and emission of a puff of the fragrance from the chamber through the orifice into the surroundings of the closure.
