Abstract
Abstract In a spraying container structure, before the sealing and blowing operations there is mounted in the valve body comprising a housing and a cover which is provided with a temporary sleeve, a closure member which is adapted to cooperate with a sealing element to close the valve. The closure member is maintained in the valve open position in the valve body during the production of the container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
212 words
In a valve for assembling with a container and thereby forming a spraying container structure, the valve comprising a housing, a cover which is provided with a temporary sleeve and is combined with said housing to form a valve body, the housing and the cover defining therebetween a chamber and each defining an axial aperture opening into said chamber, the aperture of the housing being for putting the chamber in communication with the interior of the container and the aperture of the cover communicating with the interior of the sleeve, a sealing element mounted in the chamber, a closure member mounted in said chamber to be movable between an inoperative position spaced away from the sealing element and providing for communication between the chamber and the interior of the sleeve through said cover aperture and an operative position in which it is in sealing engagement with the sealing element for sealing off the cover aperture from the chamber, elastically yieldable means interposed between the valve body and the closure member for applying the closure member against the sealing element in said operative position; the improvement comprising abutment means for temporarily maintaining the closure member in said inoperative position and destructible fixing means for temporarily fixing the abutment means to the valve body.
Claim 2
Dependent Claim
212 words
In a valve for assembling with a container and thereby forming a spraying container structure, the valve comprising a housing, a cover which is provided with a temporary sleeve and is combined with said housing to form a valve body, the housing and the cover defining therebetween a chamber and each defining an axial aperture opening into said chamber, the aperture of the housing being for putting the chamber in communication with the interior of the container and the aperture of the cover communicating with the interior of the sleeve, a sealing element mounted in the chamber, a closure member mounted in said chamber to be movable between an inoperative position spaced away from the sealing element and providing for communication between the chamber and the interior of the sleeve through said cover aperture and an operative position in which it is in sealing engagement with the sealing element for sealing off the cover aperture from the chamber, elastically yieldable means interposed between the valve body and the closure member for applying the closure member against the sealing element in said operative position; the improvement comprising abutment means for temporarily maintaining the closure member in said inoperative position and destructible fixing means for temporarily fixing the abutment means to the valve body.
Claim 3
Dependent Claim
53 words
A valve as claimed in claim 1, wherein the abutment means comprise an axial finger member and the fixing means comprise at least one series of thin substantially radially extending tabs which are capable of being cut, the sealing element defining a centre throughway aperture through which centre aperture the finger member extends.
Claim 4
Dependent Claim
59 words
A valve as claimed in claim 2, wherein the finger member has a diameter substantially equal to the diameter of the centre aperture of the sealing element and the finger member has longitudinal grooves for putting opposite sides of the sealing element in communication with each other, the grooves defining therebetween ribs in sliding contact with the sealing element.
Claim 5
Dependent Claim
34 words
A valve as claimed in claim 2, wherein the finger member has a diameter which is less than the diameter of the centre aperture of the sealing element, and has a smooth lateral surface.
Claim 6
Dependent Claim
67 words
A valve as claimed in claim 4, wherein the series of thin radial tabs are located at an end of the aperture of the cover remote from the housing, and a series of substantially radially extending branches which are thinner and longer than the tabs interconnect the finger member and the cover and are located at an end of the aperture of the cover adjacent the chamber.
