AUTOMATIC CLOSURE FOR COLLAPSIBLE TUBES Filed NOV. 21, 1959 INVENTOR: Blu FE BY fio x/S IIMM ATTORNEY Paiented Jan. 20, 1942 UNITED su'rom'ric cLospac roa COLLAPSIBLE runes 1 Bela Feldmar, Budapest, Hungary Application November 21, 1839, Serial No. 305,423
In Hungary September 1, 1989 3 Claims.
This invention relates to a dispensing valve control device for collapsible tubes, of the kind which comprises 'a rigid dish-shaped support providedwith apertures in its border and seated upon the inside wall oi the tube and behind its discharge head, and which device further comprises avalved disc, disposed within the hollow I or cavity or the dish-shaped support and underneath or behind said apertures, and provided with a valve stem which controls the dispensing mouth of the discharge head.
It is an object of this invention to provide a i highly simple and eillcient control device of this character which makes it possible respectively to open or to close instantaneously the dispensing mouth oi the tube when pressure on the tube is exerted or subsequently released.
It is a primary object this invention to create a simple valve structure without any floating packings, springs, or clamping means, operative between dish-shaped support and valve disc.
It is thus an object 0! this invention to provide within the cavity of the dish-shaped support the valve disc loosely seated and'centered as an elastically resilient means, which under .the pressure of the tube. contents entering through the apertures into the space between disc and tube head tilts about its annular line of contact with the support, or its bearing edge, and recedes into the circular space between dish-shapedsupport and disc tapering towards the line of contact between disc and support, or the bearing edge of the disc,
dish-shaped support is designated by la. The bottom oi the supportpreierably'tapers towards its center and thus forms a hollow air space within the support. The support a is secured to the inside wall of the tube by any conventional or appropriate means, as, for instance, by pressing the rim 0! the support in into a flanged recess 5 of the tube head; Figs. 1 or 2, or-into a recess 13, Fig.
4, or by pressing the tube wall into a recess I of the valve support rim, Fig. 3.
The border of the support is provided with apertures l at its edge (Fig. 2), or in proximity thereto, Figs. 1, 3 and 4, through which the tube contents maypass into the head space towards the dispensing mouth I of the tube.
.Centered within the dish-shaped valve support to and loosely bearing thereon, is the valve 4 comprising the valve disc 4b and the valve stem II which controls the dispensing mouth I. The valve disc is arranged behind vor underneath the apertures I and forms a wide brim of the valve. the valve stem being mounted upon the valve disc and-secured thereto, Fig. 2. or being integral and withdraws the valve stem from the dispensing mouth and resumes its original shape and position and closes the.dispensing mouth when thepressure upon the tube contents has been re- ,leased without the necessity of supplemental mechanical means, such as coil springs, or the like.
In the drawing: a Fig. 1 shows a longitudinal sectional view of a collapsible tube head provided with a dispensing valve control device of this invention in which the valve disc is integral with the valve stem both together forming a broad cup with a wide rim.
Fig. 2 shows a similar view of a device inwhlch the valve stem in form of a mushroom is mounted upon the disc oi inverted dish-shape.
Figs. 3 and 4 show longitudinal sectional views of twomodifications in which the valve disc is iormed with annular corrugations.
Thebody of the tube is designated by I, the head of the tubeby I, and its dispensing mouth by 3. The automatic dispensing valve control device ls arranged within the head of the tube. Its
therewith, both together forming a cup with a wide brim, Figs. 1, 3 and 4. Disc 4b is of elasticalLv resilient material as thin as possible. From the relatively large width of the elastic brim which width may be increased by annular corrugations, as shown in Figs.3 and 4, a highly effective elastic leverage of the valve results. Sealing between disc 41) and support la may be secured by fitting the disc rim closely into the edge of the dish-shaped support as shown in the drawing. I
When pressure is applied to the tube, the pressure of the tube contents which has passed through the apertures 8 into the space between valve disc" and tube head will cause the valve disc to tilt-about its bearing edge or annular line of contact with its support and to recede within the space iormed between dish-shaped support and valve disc and tapering towards said bearing edge or line of contact. The valve stem is thus withdrawn from the dispensing mouth and the tube contents will now be discharged. As soon as the pressure on the tube is released, the valve disc will resume its original shape and will advance the valve stem into its closing position at the dispensing mouth.
What I claim is:
I. A collapsible tube having a discharge head with a dispensing mouth and, interiorly or said tube and in the proximity of said mouth, a dispensing valve control device 0! the kind which comprises a rigid dish-shaped support with apertures in its border, a seat upon the inside wall of said tube for seating said dish-shaped support, a valve disc disposed within the cavity of said dishshaped support and underneath said apertures and, mounted upon said valve disc, a valve stem for controlling said dispensing mouth; said valve themselves a circular space tapering towards said line oilcontact, said disc being of resilient material and adapted when the tube and its contents are compressed to tilt by-elastic deiorma disc being loosely seated, substantially on an an- I nular line of contact upon said dish-shapedsupport, both said disc and said supportconflning between themselves a circular spacewtaper'ing to- .wards' said line of contact, said disc being of resilient material and adapted when the tube and its contents are compressed to tilt by elastic deformation about said line of contact to recede within said tapering space, and thus to withdraw said stem from contact with said' dispensing mouth, and subsequently, when the pressure is released, elastically to resume its original shape.
2. A collapsible tube having a discharge head with a dispensing mouth and, interiorly of said tube and in the proximity of said mouth, a dispensing valve control device of the kind which tion about said line of contact, to recede within said tapering space, and'thus to withdraw said stem from contact with said dispensing mouth.
and subsequently, when the pressure is released, elastically to resume its original shape. 3. A collapsibletube having a discharge head with a dispensing mouth and, interiorlyof said tube and in the proximity of said mouth, a dispensing valve control device of the kind which comprises a rigid dish-shaped support with apertures in its border, a seat upon the inside wall of said tube for seating said dish-shaped supporttaa V valve disc disposed within the cavity of said dish-' shaped support and underneath'said'apertures and, mounted upon said valve disc a valve stem. for controlling saiddispensing mouth; said disc,
- and said stem being integral with eachother and comprises a rigid dish-shaped support with apertures in its border, a seat upontheginside wall of said tube for seatingsaid"dishfshaped support, v a valve disc disposed within the cavitycf -said dish-shaped support andunderneath. said apertures and, mounted upon saidvalve disc, a valve stem for controlling said dispensing mouth; said disc forming a wide brim with annular corrugations at the foot of said stem, said valve disc being loosely seated, substantially on an annular line of contact upon said dish-shaped support,v
both said disc and said support confining between forming a cup with a wide brim,'said"valve disc being loosely seated by means of, its edge upon said dish-shaped support, both said disc and said support confining between, themselves a circular space tapering towards said valvedisc' edge, said disc being of,- resilient material and adaptedwhen the tube and its. contents are compressed to tilt about said valve disc; edge, to recede within said tapering, space and thus; to withdraw said stem from contact with said dispensing mourn isrele'a s' ed,
