Self-sealing holder for containers

A self-sealing holder for containers comprising, a first member means having a generally planar surface including a resilient deformable material adapted to exert pressure against the open mouth of a container placed in contact therewith, wherein said first member means comprises a ring-shaped support member and a relatively thin resilient membrane supported thereon so as to cover the hole in the ring-shaped member, and means for mounting said first member means so that said planar surface is parallel to and spaced apart from a second generally planar surface with the resilient membrane confronting said second planar surface so that the two confronting surfaces will seal and retain in position a container inserted therebetween.

A self-sealing holder for containers comprising a first support member having a generally planar surface and a first resilient deformable material having a generally planar surface and fixed to the first support member, said resilient deformable material being adapted to exert pressure against the open mouth of a container placed in contact therewith, a second generally planar surface parallel to and spaced apart from the first planar surface with the resilient material facing said second planar surface so that the two facing surfaces will seal and retain in position a container inserted therebetween, a spongy resilient material secured on the second planar surface, a thin rigid plate covering said spongy resilient material, a thin resilient material covering said thin rigid plate and having a relatively smooth flat surface facing the first resilient material, and a pair of opposed side walls extending at right angles to said second planar surface so as to restrain said spongy resilient material from expanding laterally.

A self-sealing holder for containers comprising a first support member having a generally planar surface and a first resilient deformable material having a generally planar surface and fixed to the first support member, said resilient deformable material being adapted to exert pressure against the open mouth of a container placed in contact therewith, said first resilient material comprising a separately formed interior air pocket, a second generally planar surface parallel to and spaced apart from the first planar surface with the resilient material facing said second planar surface so that the two facing surfaces will seal and retain in position a container inserted therebetween.
