Abstract

Art apparatus for applying spray texture to a wall or the like. The apparatus comprises an aerosol can containing pressurized spray texture material. The spray texture material is released from the can by a valve and passes through a nozzle passageway, out of a discharge opening, and on to a surface to be textured. The apparatus further comprises an outlet member that can be placed over the discharge opening to vary the effective cross-sectional area thereof. This outlet member can be in the form of a straw or tube that is inserted into the nozzle passageway or a disc or other member having a plurality of outlet orifices formed therein. The outlet member having a plurality of outlet orifices can be attached directly to an actuator member in which the dispensing passageway is formed. By rotating, sliding, or otherwise moving the outlet member relative to the actuator member, any one of the outlet orifices in the outlet member can be arranged at the end of the nozzle passageway to vary the effective cross-sectional area of the discharge opening.

Dependent claims

An apparatus for applying a desired texture onto a surface in a desired texture pattern that matches a pre-existing texture pattern, comprising:

a) a container structure defining a main chamber;
b) an actuator member;
c) an interface structure located within the container structure, where the interface structure divides the main chamber into a first sub-chamber containing texture material and a second sub-chamber containing a propellant, the texture material being characterized by its tendency to form a stream as it exits a cylindrical passageway under pressure;
d) a collection structure defining a collection portion of a dispensing passageway;
e) a discharge structure defining a discharge portion of the dispensing passageway, where fluid flowing through the discharge portion of the dispensing passageway flows along a discharge axis;
f) valve means for defining a valve portion of the dispensing passageway and for creating, in response to displacement of the actuator member into an open position, an exit path by which texture material may flow from the first sub-chamber out of the container structure through the dispensing passageway;
and
g) a spray structure defining an outlet portion of the dispensing passageway;
wherein
h) the outlet portion of the dispensing passageway is arranged adjacent to the surface such that, when the actuator member is displaced into the open position, the propellant acts on the texture material through the interface structure to cause the texture material to pass into a collection opening, through the dispensing passageway, out of a discharge opening, and onto the surface, where the texture material hardens;
and
i) the spray structure acts on the texture material within the outlet portion of the dispensing passageway to cause at least a portion of the texture material flowing through the dispensing passageway to leave the dispensing passageway at an angle with respect to discharge axis, resulting in a spray of texture material discharged from the discharge opening appropriate for depositing the texture material onto the surface in the desired texture pattern to match the pre-existing texture pattern.

9 more elements

A method of applying spray texture to a surface in a desired pattern, comprising the steps of:

a) providing a container defining a main chamber;
b) providing an actuator member;
c) mounting an interface member within the main chamber such that the interface member defines a first sub-chamber and a second sub-chamber;
d) placing texture material in the first chamber, the texture material being characterized by its tendency to form a stream as it exits a cylindrical passageway under pressure;
e) placing pressurized propellant material in the second chamber such that the propellant material acts on the texture material through the interface member;
f) providing an outlet structure defining a dispensing passageway that allows fluid flow between the first chamber and an exterior of the container, the dispensing passageway having a collection portion, a valve portion, a discharge portion, and an outlet portion, where fluid flowing through the discharge portion of the dispensing passageway flows along a discharge axis;
g) providing a valve assembly for creating, in response to displacement of the actuator member into an open position, an exit path by which texture material may flow from the first chamber, through the dispensing passageway, and to the exterior of the container;
h) arranging the outlet portion of the discharge passageway adjacent to the surface;
i) displacing the actuator member into the open position such that the propellant material forces the texture material to flow through the dispensing passageway, where the outlet structure is configured such that the portion thereof defining the outlet portion of the dispensing passageway acts on at least a portion of the texture material flowing through the dispensing passageway to cause the at least a portion of the texture material to form a spray appropriate for depositing the texture material onto the surface in the desired texture pattern to match the pre-existing texture pattern;
j) arranging the container relative to the surface such that the texture material exiting the dispensing passageway is deposited on the surface in the desired pattern;
and
k) allowing the texture material to harden.
