Abstract
Devices for dispensing material from a deformable tube comprise a shell having a top portion and a bottom portion. The shell comprises two shell pieces, the shell defining a compartment adapted for receiving a deformable tube and having an aperture in its top portion. Each shell piece comprises a press portion having a groove surrounding the press portion and a hinge located in the bottom portion connecting the press portion to the shell piece. The inner surfaces of the press portions have pressing features configured to squeeze a deformable tube from the bottom of the tube to the top of the tube.
Claims25
A device for dispensing material from a deformable tube comprising:
- a shell having a top portion and a bottom portion and comprising two shell pieces, the shell defining a compartment adapted for receiving a deformable tube and having an aperture in its top portion;
- wherein each shell piece comprises a press portion having a groove surrounding the press portion and a hinge located in the bottom portion connecting the press portion to the shell piece, the inner surfaces of the press portions having pressing features configured to squeeze a deformable tube from the bottom of the tube to the top of the tube.
A device for dispensing material from a deformable tube containing an internal stiffener comprising:
- a shell having a top portion and a bottom portion and comprising two shell pieces, the shell defining a compartment adapted for receiving a deformable tube and having an aperture in its top portion;
- wherein each shell piece comprises a press portion having a groove surrounding the press portion and a hinge located in the bottom portion connecting the press portion to the shell piece, the inner surfaces of the press portions having pressing features configured to press against the stiffener of a deformable tube containing an internal stiffener.
A device for dispensing material from a deformable tube comprising:
- a shell having a top portion and a bottom portion, the shell defining a compartment adapted for receiving a deformable tube and having an aperture in its top portion and an aperture in its bottom portion;
- wherein the shell comprises two press portions, each press portion having a groove surrounding the press portion and a hinge located in the bottom portion of the shell connecting the press portion to the shell, the inner surface of each press portion having pressing features configured to squeeze a deformable tube from the bottom of the tube to the top of the tube.
