Abstract
The container with thumb button in a slot is a small elongated container for liquids and viscous substances. The container with thumb button in a slot comprises an elongated tubular housing with a small opening at one end and a slot extending from the other end to approximately half the length of the elongated tubular housing. A piston is disposed near the end of the elongated tubular housing with the slot. The piston has a raised thumb button near the end that is disposed near the end of the elongated tubular housing. The raised thumb button is engaged to a ratchet mechanism to enable the piston to move back and forth in the elongated tubular housing in predetermined steps. A liquid or viscous substance is disposed in the elongated tubular housing between the small opening at one end of the elongated tubular housing and the piston wherein when the piston is urged toward the liquid or viscous substance in the elongated tubular housing, the liquid or viscous substance will be extracted from the elongated tubular housing through the small opening at the end of the elongated tubular housing.
Description
- The present invention relates generally to a small container for a liquid or viscous substance. More specifically, the present invention relates to a small elongated container for liquid or viscous substance with a sliding piston delivery system.
- Small containers in the general form of an elongated tube are commonly used to distribute small quantity of liquid and cream. Such containers are usually made as small as possible, particularly if it is used to distribute samples or if the contents are expensive and only a very small amount is necessary. However, due to the capillary action of the liquid or viscosity of the cream, there is a limitation to how small of a diameter of the container may be used and still allow the content to be dispensed from the container.
- If the diameter of the container is too small, the content cannot be dispensed from the container due to the capillary action of the liquid or the viscosity of the cream. One method of resolving this difficulty is to use a soft compressible container to enable the compression of the container to force its contents out of the container. However, this type of container suffers the disadvantage that it can easily and accidentally be compressed thereby leaking its contents. Also, it is extremely difficult, if not impossible, to completely remove all of the contents in these type of containers. Furthermore, once the soft compressible container is compressed, it is very difficult, if not virtually impossible, to restore it to its original shape or to prevent entry of air due to the vacuum created after the compression force is removed and the soft compressible container attempts to return to its original shape.
- There is a point where the diameter of the container is made as small as possible and yet still allows the liquid in the container to be dispensed with ease. Most small liquid sample containers are made with cross-sections at this minimum diameter. However, even at this minimum diameter, the container is still too large and not economical for dispensing expensive samples. Much more liquid or cream than necessary for a sample must still be filled in the container or the container will have a large void that appears to be left from evaporated liquid.
- Although a smaller diameter container is desirable, it has not been possible due to the physical phenomenon of capillary action of the liquid and the viscosity of the cream that limits how small a diameter the container may have. The present invention is a simple yet effective means to allow a very small diameter container to be used for dispensing minute amount of liquid or cream samples efficiently and economically.
- The container with thumb button in a slot is a small elongated container for liquids and viscous substances. The container with thumb button in a slot comprises an elongated tubular housing with a small opening at one end and a slot extending from the other end to approximately half the length of the elongated tubular housing. A piston is disposed near the end of the elongated tubular housing with the slot. The piston has a raised thumb button near the end that is disposed near the end of the elongated tubular housing. The raised thumb button is engaged to a ratchet mechanism to enable the piston to move back and forth in the elongated tubular housing in predetermined steps. A liquid or viscous substance is disposed in the elongated tubular housing between the small opening at one end of the elongated tubular housing and the piston wherein when the piston is urged toward the liquid or viscous substance in the elongated tubular housing, the liquid or viscous substance will be extracted from the elongated tubular housing through the small opening at the end of the elongated tubular housing.
- In an alternate embodiment, the container with thumb button in a slot comprises an elongated tubular housing with two separate channels leading to two separate small openings at one end and a slot extending from the other end to approximately half the length of the elongated tubular housing. Two pistons that are affixed together at a common end are disposed near the end of the elongated tubular housing with the slot. The common end of the pistons has a raised thumb button and is disposed near the end of the elongated tubular housing. The raised thumb button is engaged to a ratchet mechanism to enable the pistons to move back and forth in the two channels in predetermined steps. A liquid or viscous substance is disposed in each of the channels in the elongated tubular housing between the small opening at one end of the elongated tubular housing and the pistons wherein when the pistons are urged toward the liquid or viscous substance in the elongated tubular housing, the liquid or viscous substance will be extracted from the elongated tubular housing through the small openings at the end of the elongated tubular housing.
