Container system with a removable cap

Abstract

Storage and dispensing systems are provided. In various embodiments, systems of the present disclosure provide safety feature to prevent or limit the risk of a child or minor opening the system. Embodiments of the present disclosure further comprise novel cap and closure arrangements including, for example, features that are operable to automatically load or fill a pipette of the system.

What is claimed is: 
     
         1 . A cap system for use with a container, comprising:
 an inner cap having an inner surface that defines an interior volume, the inner cap having a slot extending through an outer surface to the inner surface;   a button at least partially disposed in the interior volume of the inner cap, the button having a ridge extending from an outer surface of the button and having a protrusion extending from the outer surface of the button into the slot of the inner cap such that the button can move relative to the inner cap along a longitudinal axis;   a pliable bulb at least partially disposed within the button, wherein the bulb is compressible from a first volume to a smaller second volume; and   an outer cap disposed about the inner cap, the outer cap having a cam surface extending from an inner surface of the outer cap, wherein rotation of the outer cap relative to the inner cap moves the cam surface into the ridge of the button and drives the button along the longitudinal axis relative to the inner cap, which causes the button to compress the bulb from the first volume to the smaller second volume.   
     
     
         2 . The cap system of  claim 1 , further comprising a threaded member disposed within the outer cap, the threaded member having teeth at an upper end that selectively engage teeth at a lower end of the inner cap, wherein, with the teeth engaged, rotation of the inner cap rotates the threaded member to selectively engage and disengage the threaded member from the container. 
     
     
         3 . The cap system of  claim 2 , wherein the threaded member comprises a threaded inner surface at a lower end, wherein the threaded inner surface is configured to complement a threaded outer surface of the container. 
     
     
         4 . The cap system of  claim 2 , wherein a force acting on the outer cap along the longitudinal axis drives the outer cap into the inner cap, and the teeth on the inner cap engage the teeth on the threaded member. 
     
     
         5 . The cap system of  claim 1 , further comprising a pipette in fluid communication with the pliable bulb, wherein fluid is expelled from the pipette as the pliable bulb compresses from the first volume to the smaller second volume. 
     
     
         6 . The cap system of  claim 1 , wherein a force acting on the button in the longitudinal direction drives the button into the pliable bulb to compress the pliable bulb from the first volume to the smaller second volume. 
     
     
         7 . The cap system of  claim 1 , wherein rotation of the outer cap in an opposing direction relative to the inner cap moves the cam surface off of the ridge, which allows the pliable bulb to expand from the smaller second volume to the first volume, and the pliable bulb drives the button along the longitudinal axis relative to the inner cap. 
     
     
         8 . A cap system for use with a container, comprising:
 an outer cap having an interior volume;   a threaded member positioned in the interior volume of the outer cap, the threaded member having a threaded inner surface at a lower end and having a plurality of teeth at an upper end;   an inner cap positioned in the interior volume of the outer cap, the inner cap having a plurality of teeth at a lower end of the inner cap, wherein the inner cap is freely rotatable relative to the threaded member until a sufficient force is applied to the outer cap along a longitudinal axis, and the outer cap contacts the inner cap to cause the plurality of teeth of the inner cap to engage the plurality of teeth of the threaded member such that the threaded inner surface of the threaded member can selectively engage and disengage from a threaded outer surface of the container;   a pliable bulb at least partially positioned in the interior volume of the outer cap; and   a pipette in fluid communication with the pliable bulb, wherein the pliable bulb is compressible to move fluid out of the pipette and into the container, and the pliable bulb is expandable to move fluid from the container and into the pipette.   
     
     
         9 . The cap system of  claim 8 , further comprising a button disposed about the pliable bulb, wherein movement of the button along the longitudinal axis in a first direction causes the pliable bulb to compress from a first volume to a second volume and move fluid out of the pipette and into the container. 
     
     
         10 . The cap system of  claim 9 , wherein, in a manual mode of operation, a longitudinal force acts on the button to cause the button to move along the longitudinal axis in the first direction and move fluid out of the pipette and into the container. 
     
     
         11 . The cap system of  claim 9 , wherein the button has a ridge extending from an outer surface, and the outer cap has a cam extending from an inner surface, wherein rotation of the outer cap about the longitudinal axis causes the cam to engage the ridge and the button to move along the longitudinal axis. 
     
     
         12 . The cap system of  claim 11 , wherein, in an auto-loading mode of operation, a first longitudinal force acts on the outer cap to cause the plurality of teeth of the inner cap to engage the plurality of teeth of the threaded member, and a first rotational force acts on the outer cap to drive the cam into the ridge, move the button along the longitudinal axis in the first direction, and move fluid out of the pipette and into the container, and the first rotational force causes the threaded inner surface of the threaded member to engage the threaded outer surface of the container. 
     
     
         13 . The cap system of  claim 12 , wherein, in the auto-loading mode of operation, a second longitudinal force acts on the outer cap to cause the plurality of teeth of the inner cap to engage the plurality of teeth of the threaded member, and a second rotational force acts on the outer cap to back the cam off of the ridge to allow the pliable bulb to expand, move the button along the longitudinal axis in a second direction, and move fluid from the container and into the pipette, and the second rotational force causes the threaded inner surface of the threaded member to disengage the threaded outer surface of the container.
