(Cl. 221-60) 'This invention relates to -closures, and more portion of the sealing cup member has a U-'shaped h particularly to closure devices for collapsible tubes, valve slit 8 therein forming a flap 9 which is adapt such as for example, toothpaste tubes and the ed _to open up and form a valve opening Ill for al . lowing passage of the contents of the tube when it like. 5 The principal object- of the present invention is is desired to remove the contents therefrom. In order to keep the flap 9 closed and thus keep i to provide a collapsible tubeclosure device which will seal the discharge opening through the neck l the discharge opening 4 of the tube sealed against of the'tube when the device is closed and prevent removal of the contents, a'ilat metallic closure escape of the contents from the tube even though member I I is mounted on the tube neck adjacent to the flat outer end portion of the sealing cup 10 10 considerable pressure be applied thereto. Other objects are to provide a tube closure de member for sliding movement across the dis vice that can be readily manipulated to open and charge opening. While the closure member may close the discharge opening; that is simple in con be slidably- mounted on the tube neck in any sult- A ` struction; and that is comparatively inexpensive able manner, I prefer to provide the end of the tube neck with two ears I2 located at opposite l5 15 to manufacture. The invention consists in the collapsible tube sides of the discharge opening 4 through the neck, closure device, and in the parts, combinations, andy and the closure member is mounted for slidingarrangements of parts hereinafter described and movement between said ears and the end of the tube neck. Preferably, the ears I2 may be beveled claimed.
