A child-resistant bottle cap overshell and method for construction thereof is provided. A top cover has an oval shape. A body extends from an outer perimeter of the top cover and is sized to fit over a bottle cap on a bottle. At least two cutouts are formed in the top cover adjacent to the outer perimeter. A plurality of ridges are formed on an inner surface of the body on a bottom end opposite the top cover.

A needleless connector caps is provided with one or more vents allowing air to pass around the cap, for example in a case where a cap may be accidentally lodged in a position completely concentric with a patient's throat. Configuration of structural elements making up a cap exterior can provide one or more openings or channels in the cap that remain unblocked and extend from the base to the top side of the cap forming one or more vents allowing air to pass through the cap.

A liquid dispensing nozzle includes a liquid dispensing opening and a removable cap configured to cover the liquid dispensing opening. The removable cap includes an outer casing and an inner casing that are coaxial and configured to move relative to each other in an axial direction of the nozzle between an unscrewing configuration wherein a pressing force applied to the removable cap is greater than a predetermined threshold, and a safety configuration wherein a pressing force applied to the cap is lower than the predetermined threshold, wherein the outer casing is configured to freewheel relative the inner casing in the first direction. A rotation of the outer casing in a first direction drives by friction a rotation of the inner casing in the same first direction to unscrew the cap, wherein the pressing force is different from a force required to rotate the cap in the first direction.

A medical liquid supply device that includes: a container including a containing portion with a mouth (16); an interior cap (30); and an exterior cap (60). The interior and exterior caps (30, 60) include a ratchet mechanism (50, 80). The interior cap (30) includes: an interior-cap main body (32) and an interior-cap protrusion (54). The interior-cap main body (32) includes a contact ring (44). The exterior cap (60) includes: an exterior-cap main body (62); and an exterior-cap protrusion (84) configured to be engaged with the interior-cap protrusion (54). The contact ring (44) is distant from the interior-cap protrusion (54) in the radial direction of the interior-cap main body (32).

[Object] It is an object of the present invention to provide a liquid medicine supply device configured to reliably prevent infants and children from accidentally opening the liquid medicine supply device. [Solutions] A liquid medicine supply device (1) including a container (10) with a containing portion (11) and a mouth (16); an interior cap (30); and an exterior cap (60), in which the interior and exterior caps (30, 60) include a ratchet mechanism (50, 80). The ratchet mechanism allows the exterior and interior caps (60, 30) to be integrally rotated when the exterior cap is rotated relative to the mouth under a condition of the exterior cap (60) pressed against the interior cap whereas the ratchet mechanism allows the exterior cap (60) to be rotated relative to the interior cap (30) when the exterior cap is rotated relative to the mouth under a condition of the exterior cap (60) which is not pressed against the interior cap. An axial direction of the mouth (16) is inclined from an axial direction of the containing portion (11) at a predetermined angle (θ).

The interior and exterior caps (30, 60) include a ratchet mechanism (50, 80). The interior cap (30) includes: an interior-cap main body (32) with a contact ring (44) to tightly close the container (10); and an engaging portion (50). The exterior cap (60) includes: an exterior-cap main body (62); and an engaged portion (80). The engaged portion (80) and the engaging portion (50) constitute the ratchet mechanism. The contact ring (44) is distant from the engaging portion (50) in a radial direction of the interior-cap main body (32).

A tamper-resistant nozzle assembly for preventing the unwanted or unintentional dispensing of a material from a container. The nozzle assembly may comprise a base adapted to fit on top of a container holding the material, a mechanism located within the base and configured to provide tamper-resistant properties for the nozzle assembly, a nozzle connected to the base and having a pair of diametrically opposed tabs extending downwardly therefrom into the base, the tabs being capable of travelling radially inward when squeezed by a user, whereby, in a locked state, the mechanism limits the travel of the tabs such that (1) the nozzle cannot rotate relative to the base, and (2) the nozzle cannot be depressed to release the material from the container. When a user squeezes the tabs, the mechanism is in an unlocked state and permits the rotation of the nozzle relative to the base, to thereby enable the nozzle to be depressed relative to the base to allow it to dispense the material from the container.

Provided is a system a push and turn child safety container with finger indents. The child safety container has an outer body having a first circular element bounded by a first circumferential wall extending normally away from the first circular element for a first distance, the distal end of the first outer wall having a retainer with an inner body having a second circular element bounded by a second circumferential wall extending normally away from the second circular element a second distance less than the first distance with an inner surface of the second circumferential wall having a first screw thread, the inner body nested with in the outer body and retained by the retainer. The screw element characterized by a circular first element having an outer circumferential wall having a plurality of indents structured and arranged to receive a user's finger, each of the plurality of indents providing an abutment surface to receive a substantial portion of a user's fingertip, the circumferential wall sections between the indents being substantially smooth; and a threaded circular wall extending normally from a circular first element below the indents, the threaded collar structured and arranged to be disposed within the inner body and engage the first threads of the inner surface of the second circumferential wall to temporarily bind the screw element with the inner body, the threaded collar defining at least a portion of a storage space for the safety container.
