Container closure with product-discharge control system
First Claim
1. A package comprisinga container formed to include an interior product-storage region and an opening arranged to open into the interior product-storage region,a dispensing cap formed to include a discharge passageway and coupled to a neck included in the container and,a flow control valve coupled to the container to lie between the dispensing cap and the container and formed to include a normally-closed discharge aperture in fluid communication with the interior product-storage region of the container and with the discharge passageway of the dispensing cap,wherein the flow control valve is made from a film and configured to provide means for regulating flow of fluid material from the interior product-storage region of the container into the discharge passageway of the dispensing cap through the normally closed discharge aperture in the event the container is squeezed to pressurize fluid material stored in the interior region of the container,wherein the film includes an upper layer arranged to lie between the dispensing cap and the container and a core layer located between the upper layer and the container,wherein the film further includes a lower layer located between the core layer and the container, wherein the upper layer is made from a first polymeric material, the core layer is made from a different second polymeric material.

Abstract
A package includes a container and a closure arranged to close an opening into an interior region formed in the container. The closure includes a dispensing cap formed to include a body adapted to be coupled to a neck of the container and a product-discharge spout coupled to the body to discharge product stored in the container that passes from the interior region of the container into a discharge passageway formed in the product-discharge spout.

1. A package comprising
a container formed to include an interior product-storage region and an opening arranged to open into the interior product-storage region, a dispensing cap formed to include a discharge passageway and coupled to a neck included in the container and, a flow control valve coupled to the container to lie between the dispensing cap and the container and formed to include a normally-closed discharge aperture in fluid communication with the interior product-storage region of the container and with the discharge passageway of the dispensing cap, wherein the flow control valve is made from a film and configured to provide means for regulating flow of fluid material from the interior product-storage region of the container into the discharge passageway of the dispensing cap through the normally closed discharge aperture in the event the container is squeezed to pressurize fluid material stored in the interior region of the container, wherein the film includes an upper layer arranged to lie between the dispensing cap and the container and a core layer located between the upper layer and the container, wherein the film further includes a lower layer located between the core layer and the container, wherein the upper layer is made from a first polymeric material, the core layer is made from a different second polymeric material.

2. A package comprising
a container formed to include an interior product-storage region and an opening arranged to open into the interior product-storage region, a dispensing cap formed to include a discharge passageway and coupled to a neck included in the container and, a flow control valve coupled to the container to lie between the dispensing cap and the container and formed to include a normally-closed discharge aperture in fluid communication with the interior product-storage region of the container and with the discharge passageway of the dispensing cap, wherein the flow control valve is made from a film and configured to provide means for regulating flow of fluid material from the interior product-storage region of the container into the discharge passageway of the dispensing cap through the normally closed discharge aperture in the event the container is squeezed to pressurize fluid material stored in the interior region of the container, wherein the film includes an upper layer arranged to lie between the dispensing cap and the container and a core layer located between the upper layer and the container, wherein the film further includes a lower layer located between the core layer and the container, wherein the upper layer is made from a first polymeric material, the core layer is made from a different second polymeric material, and the bottom layer is made from the first polymeric material, the upper layer has a thickness of about 1 mil, the bottom layer has a thickness of about 1 mil, and the core layer has a thickness of about 4 mil to about 5 mil.

16. A package comprising
a container formed to include an interior product-storage region and an opening arranged to open into the interior product-storage region, a dispensing cap formed to include a discharge passageway and coupled to a neck included in the container and, a flow control valve made from a film having a polymeric layer and a polyester layer and coupled to the container to lie between the dispensing cap and the container and formed to include a normally-closed discharge aperture in fluid communication with the interior product-storage region of the container and with the discharge passageway of the dispensing cap, the flow control valve being configured to provide means for regulating flow of fluid material having a viscosity from the interior product-storage region of the container into the discharge passageway through the normally closed discharge aperture in response to squeezing the container to apply pressure to the fluid material stored in the interior region of the container while blocking leaks of fluid material from moving through the normally closed aperture when the container is arranged to cause the dispensing cap to be located between ground underlying the package and the container and when squeezing has ceased so that no pressure is applied to the fluid material.
