Paint dispensing method and apparatus
A paint container for use with a reusable dispensing apparatus, and the reusable dispensing apparatus are provided to dispense paint under pressure. The paint container includes a housing defining an interior space that is devoid of an internal valve, and a combination comprising a propellant combined with paint within the interior space. A container cap is installed on the housing to enclose the propellant combined with the paint within the interior space at an elevated pressure, and defines a channel that cooperates with a portion of the housing. A compressible gasket is disposed within the channel and compressed between the container cap and the portion of the housing to form a seal that interferes with an escape of the propellant combined with the paint between the container cap and the housing. A releasable fastener engages releasably couples the reusable dispensing apparatus to the container cap.
1 . An apparatus, comprising:
a fluid dispensing apparatus configured for controlling an expulsion of fluid from a container that is storing a fluid to be discharged in an interior space that lacks an internal valve to control discharges of the fluid, the container comprises a pierceable membrane and a coupling element, the fluid dispensing apparatus is further configured to cooperate with the coupling element to releasably couple the fluid dispensing apparatus to the container, the fluid dispensing apparatus comprising:
a valve body comprising:
a releasable fastener that engages a compatible connector provided to the container to couple the fluid dispensing apparatus to the container, and
a support member that protrudes from the valve body and cooperates with a portion of a protective cap;
a valve coupled to the valve body to be supported externally of the container while the reusable fluid dispensing device is installed on the container to control the expulsion of the fluid from the container;
a nozzle in fluid communication with the valve, the nozzle being manually adjustable to open the valve and direct fluid expelled from the container to pass through the valve; and
a piercing member that defines an interior passage and is positioned to puncture a membrane enclosing the container to establish fluid communication between the container and the valve.
2 . The apparatus of claim 1 , wherein the support member is integrally formed with the valve body as a monolithic structure.
3 . The apparatus of claim 1 , wherein the support member defines an aperture that is compatible to receive the portion of the protective cap.
4 . The apparatus of claim 3 , where the aperture is shaped to receive a rib that extends about an interior surface of the protective cap.
5 . The apparatus of claim 1 , further comprising a notification provided to a portion of the valve body.
6 . The apparatus of claim 5 , wherein the notification is indelibly formed as part of the valve body.
7 . The apparatus of claim 5 , wherein the notification is applied to a surface of the valve body.
8 . The apparatus of claim 5 , wherein the notification comprises text warning about a possible condition of using the reusable fluid dispensing apparatus.
9 . The apparatus of claim 1 , further valve body further comprising:
a domed region having a peripheral wall, and
the support member that protrudes in a radially outward direction from the domed region.
10 . The apparatus of claim 1 , wherein the protective cap comprises a cylindrical shell defining a finger notch, and the support member coupled the protective cap to the fluid dispensing apparatus where the cylindrical shell extends at least partially about the nozzle and the finger notch is adjacent to the nozzle, allowing manual manipulation of the nozzle through the finger notch.
11 . An apparatus, comprising:
a container, the container storing a fluid to be discharged in an interior space that lacks an internal valve to control discharges of the fluid, the container further comprising a pierceable membrane and a coupling element;
a fluid dispensing apparatus for controlling an expulsion of fluid from the container, the fluid dispensing apparatus cooperates with the coupling element to releasably couple the fluid dispensing apparatus to the container, the fluid dispensing apparatus comprising:
a valve body comprising:
a releasable fastener that engages a compatible connector provided to the container to couple the fluid dispensing apparatus to the container, and
a support member that protrudes from the valve body and cooperates with a portion of a protective cap;
a valve coupled to the valve body to be supported externally of the container while the reusable fluid dispensing device is installed on the container to control the expulsion of the fluid from the container;
a nozzle in fluid communication with the valve, the nozzle being manually adjustable to open the valve and direct fluid expelled from the container to pass through the valve; and
a piercing member that defines an interior passage and is positioned to puncture a membrane enclosing the container to establish fluid communication between the container and the valve.
12 . The apparatus of claim 11 , wherein the support member is integrally formed with the valve body as a monolithic structure.
13 . The apparatus of claim 11 , wherein the support member defines an aperture that is compatible to receive the portion of the protective cap.
14 . The apparatus of claim 13 , where the aperture is shaped to receive a rib that extends about an interior surface of the protective cap.
15 . The apparatus of claim 11 , further comprising a notification provided to a portion of the valve body.
16 . The apparatus of claim 15 , wherein the notification is indelibly formed as part of the valve body.
17 . The apparatus of claim 15 , wherein the notification is applied to a surface of the valve body.
18 . The apparatus of claim 15 , wherein the notification comprises text warning about a possible condition of using the reusable fluid dispensing apparatus.
19 . The apparatus of claim 11 , further valve body further comprising:
a domed region having a peripheral wall, and
the support member that protrudes in a radially outward direction from the domed region.
20 . The apparatus of claim 11 , wherein the protective cap comprises a cylindrical shell defining a finger notch, and the support member coupled the protective cap to the fluid dispensing apparatus where the cylindrical shell extends at least partially about the nozzle and the finger notch is adjacent to the nozzle, allowing manual manipulation of the nozzle through the finger notch.
