A fluid dispensing device includes a barrel having a hollow interior, an inlet opening at one end and an open second end. A plunger is slidably received within the hollow interior of the barrel through the open second end and has an outlet passage extending through its length to an outlet outside of the barrel. An inlet valve is disposed at the inlet opening of the barrel and an outlet valve is carried within the outlet passage of the plunger. A closure is secured to the barrel over the open end of the barrel and over the plunger, with the closure urging the plunger into the barrel against the inlet valve such that the plunger engages the inlet valve and holds the inlet valve closed. Opening of the closure permits the plunger to be withdrawn from the barrel to draw fluid into the barrel through the inlet opening and the inlet valve. Return of the plunger into the barrel closes the inlet valve and forces the fluid in the barrel through the outlet passage and the outlet valve in the plunger.
Complementary load bearing surfaces are provided on a child resistant closure and container combination forming at least one load carrying member preventing axial forces under stacking load conditions from causing biasing, child resistance, and/or seal failure when the closure is in a stacking position on the complimentary container.
A child-resistant dispensing closure for a container may include one or the other or both of a dispensing cover non-removably securable to a container, or an outer cover non-removably securable and rotatable with respect to the inner cover and cooperable with the dispensing cover to render the closure child-resistant. According to another embodiment, an outer cover may include a flange to aid users in pushing and turning the outer cover with their fingers.

Child-resistant closure, package and method of making
A closure includes a skirt and internal lugs on the skirt. The skirt has an undulating circumferential contour that includes alternate outwardly convex and outwardly concave portions, with the internal lugs being disposed within the outwardly concave portions of the skirt. The skirt preferably is sufficiently flexible to allow the outwardly concave portions of the skirt to assume an outwardly convex geometry as a result of outward pressure on the internal lugs during demolding of the closure. The closure thus may be simply axially stripped from the mold core during the demolding operation without requiring movement of portions of the mold core to clear a path for travel of the lugs. The lugs preferably are shaped as an inverted U that opens toward a free edge of the skirt, further to facilitate demolding of the closure.
A child-resistant package includes a container having an open mouth, a conical external surface around the open mouth that widens away from the mouth and a wall extending from the conical external surface. A closure has a base wall, and a peripheral skirt having a first portion adjacent to the base wall and a second portion removably connected to the first portion. An annular first wall extends from the base wall at a position radially inward from the skirt for spring/sealing engagement with the conical external surface of the container. A second wall extends from the base wall at a position radially inward from the first wall and, preferably, at an outward conical angle to the base wall. The second portion of the skirt and the wall on the container have interlocking elements that resist removal of the closure from the container in a child-resistant mode of operation absent a force against the first wall to disengage the interlocking elements. The second portion of the skirt is frangibly removable from the first portion to remove the interlocking elements from the skirt so that the closure is securable to the container in a non-child-resistant mode of operation with the second wall received by snap-fit within the container mouth.
A package that has both child-resistant and non-child-resistant modes of operation. A container has an end with an open mouth surrounded by a container wall with a central axis and at least one first lock element extending radially outwardly from the wall. A closure includes an annular base wall having inner and outer peripheral edges. A cylindrical skirt extends from the outer peripheral edge of the base wall, and at least one second lock element is disposed on the skirt. A projection extends axially from the inner peripheral edge of the base wall in a direction opposite from the skirt. The projection has an annular sidewall spaced radially inwardly from the outer peripheral edge of the skirt. The closure is adapted to be secured to the container in a child-resistant mode of operation with the second lock element on the skirt releasably engaged with the first lock element on the container wall, and with the inner peripheral edge of the base wall in resilient engagement with the outer surface of the container wall to bias the lock elements in engagement with each other and to seal the package. The closure is adapted to be inverted and secured to the container in a non-child-resistant mode of operation with the annular sidewall of the projection received in plug-sealing engagement within the container mouth.
A method and apparatus for injection molding an article (10) including a radially extending child resistant feature (22).
