Child Resistant Bulk Dose Dispensing Unit

Abstract

Child-resistant bulk dose dispensing packaging unit, and a method for opening the packaging unit, including a container and a lid engaged with the container. The container includes a reservoir, an aperture at a top end of the reservoir, and a protrusion extending from a surface of the container. The lid engages with the container and slides between a closed position and an open position. The lid includes a top wall, a side wall extending down from an outer edge of the top wall, and a post configured to engage the protrusion at a first position when the lid is closed so as to keep the lid closed. At least a portion of the post extends substantially parallel to the side wall at a distance from the side wall. Pressing the side wall inward places the post at a second position, wherein at the second position the post is disengaged from the protrusion.

1 - 19 . (canceled) 
     
     
         20 . A packaging unit comprising:
 a container adapted to hold contents to be dispensed and having an aperture at an end thereof, the aperture being sized to dispense the contents therethrough;   a lid configured to slideably engage the container about the end thereof, the lid being slideable in a first direction between a closed position in which the lid covers the aperture and an open position in which the aperture is at least partially uncovered,   wherein the lid comprises:   a top wall;   a side wall extending from the top wall and including at least one resilient portion capable of being deflected in a direction substantially perpendicular to the first direction so as to disengage the lid from the container when in the closed position such that the lid is capable of sliding in the first direction to the open position.   
     
     
         21 . The packaging unit of  claim 20  wherein the container comprises a lip having a protrusion extending therefrom. 
     
     
         22 . The packaging unit of  claim 20  wherein the lid further comprises a post extending from the top wall and being spaced apart from the side wall in a substantially parallel arrangement, the post being configured to engage the protrusion at a first position when the lid is in the closed position so as to limit opening of the lid along the first direction, and the post being further configured such that deflection of the at least one resilient portion displaces the post to a second position wherein the post is disengaged from the protrusion of the lip. 
     
     
         23 . The packaging unit of  claim 21  wherein the protrusion comprises a protrusion blunt surface and a protrusion tapered surface on opposite ends thereof. 
     
     
         24 . The packaging unit of  claim 22  wherein the post comprises a post blunt surface and a post tapered surface on opposite ends thereof, wherein the protrusion blunt surface is configured to engage the post blunt surface at the first position. 
     
     
         25 . The packaging unit of  claim 22  wherein the lid comprises a linkage connecting the at least one post to the at least one resilient portion of the side wall, the linkage being configured to transmit deflection of the at least one resilient portion to the at least one post so as to be capable of displacing the post to the second position. 
     
     
         26 . The packaging unit of  claim 20 , wherein the container comprises at least one rail disposed proximate to the end at which the lid is engaged, the at least one rail extending parallel to the first direction, the lid comprising at least one slide extending from the top wall and being configured to cooperate with the at least one rail during movement of the lid in the first direction. 
     
     
         27 . The packaging unit of  claim 22 , wherein the container comprises a stopper extending from the lip thereof and arranged in an orientation substantially perpendicular to the slide, the stopper being configured to engage the at least one slide during movement of the lid in the first direction so as to limit movement of the lid in the first direction. 
     
     
         28 . The packaging unit of  claim 20 , wherein the top wall of the lid comprises a catch and the container defines a recessed area, the catch and the recessed area being configured to cooperate to limit sliding of the lid beyond a predetermined limit. 
     
     
         29 . The packaging unit of  claim 20 , wherein the lid comprises a top wall, a side wall extending from the top wall, a lip extending from the side wall, and a seal configured to overlie the aperture when the lid is in the closed position. 
     
     
         30 . The packaging unit of  claim 21 , wherein the container defines a groove configured to receive the lip when the lid is in the closed position. 
     
     
         31 . The packaging unit of  claim 20 , wherein the lid comprises a top wall, a side wall extending from the top wall, and, a tabbed portion including a post and the at least one resilient portion, and the container further comprising a lip having a protrusion extending therefrom, the post being configured to cooperatively engage the protrusion to maintain the lid in the closed position. 
     
     
         32 . The packaging unit of  claim 31 , wherein the container further comprises at least one slidable attachment mechanism configured to facilitate the sliding of the lid in the first direction along the container. 
     
     
         33 . A method for dispensing a product, the method comprising:
 providing a product in a packaging unit of  claim 20 : imparting a force on the lid so as to deflect the at least one resilient portion of the side wall in a direction substantially perpendicular to the first direction to disengage the lid from the container; and simultaneously sliding the lid in the first direction during deflection of the at least one resilient portion such that the lid is moved to the open position and the aperture is at least partially uncovered.
