Abstract
Described are applicators having a plunger with a plunger body, and a tube having a receptacle end for insertion of the plunger, and a connector end formed of flexible plastic material having a bull-nose shape. As an example, the plunger body can include a viewing window. As another example, the connector end has an internal surface that is free of threaded connectors. The connector end can also have a snap-fit coupling design to couple to a snap-fit nozzle. The snap-fit nozzle can be connected to an adaptor cap or an administering tool of a metering dispenser.
Claims12
An applicator system comprising:
- an applicator comprising:
- a tube comprising a receptacle end and a connector end opposite the receptacle end, wherein the tube defines a hollow core having a core wall extending from the connector end to the receptacle end, and wherein a smallest inner diameter of the tube is at the connector end of the tube;
- and
- a plunger comprising a plunger body, the plunger body comprising a tip and a flared end opposite the tip, wherein at least the tip of the plunger body is movable within the hollow core, wherein the plunger is monolithically formed, and wherein the flared end is outside of the hollow core;
- and
- an administering tool comprising a dispenser nozzle, wherein the dispenser nozzle comprises a nozzle tip, and wherein the nozzle tip of the dispenser nozzle is receivable within the hollow core at the connector end of the tube such that the nozzle tip of the dispenser nozzle abuts the tip of the plunger body within the hollow core prior to loading of a flowable composition within the hollow core.
An applicator system comprising:
- an applicator comprising:
- a tube defining a hollow core;
- and
- a plunger comprising a plunger body, the plunger body comprising a tip and an end opposite from the tip, wherein the plunger is monolithically formed, wherein the plunger is movable within the hollow core between a dispensed position, a loaded position, and a filled position, wherein a distance between the tip and a connector end of the tube in the loaded position is greater than a distance between the tip and the connector end in the dispensed position and less than a distance between the tip and the connector end in the filled position, wherein the plunger is in the loaded position prior to loading of a flowable composition within the hollow core, and wherein the end of the plunger is outside of the hollow core in the dispensed position, the loaded position, and the filled position;
- and
- a dispenser comprising:
- a dispenser nozzle that is at least partially receivable within the hollow core of the tube such that the dispenser nozzle abuts the tip of the plunger body prior to loading of the flowable composition within the hollow core;
- a dispenser body configured to house the flowable composition prior to loading of the flowable composition within the hollow core;
- and
- a rotatable base that is configured to advance the flowable composition through the dispenser nozzle based on rotation of the rotatable base.
