Abstract
Abstract A tilting-type aerosol valve comprising a cup-shaped valve housing which is covered by a resilient annular discharge-valve seat. A hollow valve stem extends through the valve seat and carries an annular valve shoulder inside the housing. The shoulder is engageable with the seat to close off the discharge. Within the housing there is a supporting boss on the valve stem, located below the valve shoulder and engageable with an opposite wall of the valve housing to normally maintain the valve shoulder and seat engaged whereby the valve is closed. The stem can be tilted, however, because the shoulder can compress a localized area of the seat. This separates another portion of the shoulder from the seat, whereby liquid can flow from the housing, but through the hollow valve stem.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
222 words
A tilt-slide valve construction for an aerosol dispenser, comprising in combination: a. a valve housing having a chamber for receiving liquid from the container, and having an unyielding transverse wall including a solid imperforate portion, said wall defining one side of said chamber; b. a resilient, apertured valve seat constituting an opposite side of said chamber; c. a valve part having a hollow shank portion extending through the aperture of the valve seat; d. said valve part having an annular valve shoulder disposed in the liquid-receiving chamber of the housing and engageable with the resilient valve seat to close the aperture thereof; e. said valve part having a side passage disposed adjacent the valve shoulder and communicating with the hollow of the shank portion, said part further having a solid and unyielding abutment portion including a slide surface engageable with and slidable on the imperforate portion of the unyielding transverse wall of the valve housing when the valve part is tilted; f. the tilting of the valve part unseating the shoulder thereof from the valve seat whereby liquid from the chamber can flow into the hollow shank portion through the said side passage; g. said abutment portion of the valve part supporting the part on the transverse wall of the valve housing with the valve shoulder engaged with said resilient valve seat.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
68 words
A valve construction as in claim 1, wherein: a. the valve housing has a hollow boss depending from the center of said transverse wall, for supporting a dip tube; b. said wall having an inlet opening establishing communication between the hollow boss and the chamber of the valve housing; c. said inlet opening being disposed eccentrically in said wall and with respect to the bore of said boss.
Claim 4
Dependent Claim
41 words
A valve construction as in claim 1, wherein: a. the abutment portion of the valve part comprises a boss depending from the valve shoulder; b. said boss having an end portion of reduced girth, on which said slide surface is disposed.
Claim 5
Dependent Claim
29 words
A valve construction as in claim 3, wherein: a. the end portion oF the depending boss has an open recess forming an annular land which constitutes said slide surface.
Claim 6
Dependent Claim
134 words
A tilt valve construction for an aerosol dispenser, comprising in combination: a. a valve housing having a chamber for receiving liquid from the container; b. a resilient apertured valve seat constituting one side of said chamber; c. a valve part having a hollow shank portion extending through the aperture of the valve seat; d. said valve part having an annular valve shoulder disposed in the liquid-receiving chamber of the housing and engageable with the resilient valve seat to close the aperture thereof; e. said valve part having a side passage disposed adjacent and spaced from the valve shoulder, said side passage being disposed in the hollow shank portion and communicating with the bore thereof; f. said shank portion having an annular external groove spaced from the valve shoulder and communicating with said side passage.
Claim 7
Dependent Claim
134 words
A tilt valve construction for an aerosol dispenser, comprising in combination: a. a valve housing having a chamber for receiving liquid from the container; b. a resilient apertured valve seat constituting one side of said chamber; c. a valve part having a hollow shank portion extending through the aperture of the valve seat; d. said valve part having an annular valve shoulder disposed in the liquid-receiving chamber of the housing and engageable with the resilient valve seat to close the aperture thereof; e. said valve part having a side passage disposed adjacent and spaced from the valve shoulder, said side passage being disposed in the hollow shank portion and communicating with the bore thereof; f. said shank portion having an annular external groove spaced from the valve shoulder and communicating with said side passage.
Claim 8
Dependent Claim
21 words
