The present application relates to child-resistant closure and locking device for containers, and in particular, a child-resistant disk-top closure and locking device for a container.
A typical standard disk top closure is comprised of two parts, a body and a disk. The main body consists of a closure feature, such as threading or a snap for a container providing a single dispense orifice, which is disposed below the disk. The body provides the structure and disk pivot features, which hold the disk in position to either seal the container orifice, or to be pivoted to the dispense position, which allows the contained product to flow out of the orifice and pass through the disk and out of the dispense port. However, most disk-top closures do not include any child-resistant locking mechanism, or may include a locking mechanism that is overly complicated and too difficult for some elderly patients to open. What is needed is a child resistant closure and locking mechanism integrated a disk top that addresses these shortcomings in the art.
The present application provides for a disk top closure and locking system for a container that combines a disk top closure with a locking element that makes it difficult for a child to open the container, which uses an automatic locking element, and requires a rotation of parts from a dispense-disabled position, to a dispense-enabled position after unlocking the locking element.

The disk top closure system of the present application will be described with reference to
A child resistant (“CR”) disk top closure system 100 in accordance with the present application combines a disk top closure for a container 150 with a CR system, which uses an automatic locking element and requires a rotation of parts from a dispense-disabled position, to a dispense-enabled position after unlocking. The CR disk top closure system 100 comprises a main body 110, a rotating locking member 120 and a pivotable disk 130.
The main body 110 acts as a means of attachment of the closure system 100 to the container 150 and comprises a single dispense orifice functioning as a standing axle 118 perpendicular to a plane. The main body 110 includes an inner wall section 111 that is dimensioned to fit over a dispensing orifice 151 of the container 150, and to engage a neck 152 of the container orifice 151. In the embodiment illustrated in the Figures, one or more locking elements 111a are arranged within the inner wall 111 that may snap over and engage a circumferential bead 153 on the neck 152 of the dispensing orifice 151. The main body 110 can be secured to the container 150 using alternative mechanisms that retain the “child-resistant” nature of the dispensing container, including for example with internal threading inside the inner wall 111 to engage a threaded dispensing orifice 151, which may further comprises locking teeth on the bottom of a screw thread that “lock” with corresponding teeth on the shoulder of the container 150, or floating teeth, wherein one must push down on the closure system 100 in order to engage the teeth on bottom of a screw thread with corresponding teeth on shoulder of container 150.
The main body 110 further includes an outer circumferential wall 112. The outer circumferential wall 112 includes a substantially U-shaped recess 113 cutout of the outer wall 112, which is defined on one end by a vertical edge 115 and on another, opposing end by a vertical portion 114a of an extended, standing edge 114. An upper surface 116 is disposed atop the outer circumferential wall 112. The upper surface 116 comprises a slot 117 formed therein, which receives an arm 126 extending from the locking member 120. The slot 117 is formed on the perimeter of the upper surface 116 adjacent to the standing edge 114 and the recess 113, such that when the arm 126 is disposed in the slot 117, the cantilevered tab 125 of the arm 126 can be exposed in the recess 113. The standing edge 114 extends from the outer circumferential wall 112 beyond the upper surface 116 of the main body 110.
A standing axle 118 is provided on the upper surface 116 of the main body 110, and defines a passageway 118a in fluidic communication with the dispensing port 151 of the container 150 when the main body 110 is affixed to the container 150. An annular seal 111b may also be provided on the reverse side of the upper surface 116 within the inner wall 111 and beneath the standing axle 118 that is dimensioned to be received within the neck 152 of the dispensing orifice 151 to provide a seal around the dispensing orifice 151. The standing axle 118 includes a protruding annular bead 118b about its circumference, which is configured to engage the locking member 120 to secure the main body 110 to the locking member 120 in such a manner that the locking member 120 can axially rotate about the main body 110, which is in a fixed position secured to the container 150.
The rotating locking member 120 includes the mechanical framework to support the pivotable disk 130. The locking member 120 comprises a through-hole 122 passing through a floor 121 of the locking member 120, which coincides with the protruding, standing axle 118 of the main body 110, so the locking member 120 can rotate about the standing axle 118 yet remain captive on the standing axle 118. A raised rim 122a is provided around the through-hole 122, which engages the circumferential bead 118b of the standing axle 118 to inhibit disassembly of the locking member 120 from the main body 110. An outer wall 123 extends from the floor 121 of the locking member 120 (i.e., away from the upper surface 116 of the main body 110), circumferentially around the locking member 120 with a clearance area 124 formed therein.
The locking member 120 also includes an integral locking feature, which includes a cantilevered tab 125 which can be depressed or flexed from the at-rest/locked state, to the unlocked state, which then allows the rotation of the locking member 120. The locking member 120 includes an arm 126 that extends from the outer wall 123, substantially below the clearance area 124 in the outer wall 123, and the cantilevered tab 125 is arranged at one end of the arm 126. An edge 125a of the cantilevered tab 125 is concentric and interferes with the vertical edge 115 in the recess 113 on the main body 110, at rest, such that the locking member 120 cannot rotate relative to the main body 110. Once the tab 125 is depressed and the two interfering edges (125a, 115) no longer interfere, the locking member 120 can be rotated relative to the main body 110.
The disk top 130 is dimensioned so as to be substantially housed within the outer wall 123 of the locking member 120. On one side of the disk top 130, a tab 131 is provided, which can be depressed into the clearance area 124 of the locking member 120 in order to pivot the disk top 130 from a closed position to an open position. In the open position, a dispensing orifice 132, opposite the tab 131, on the disk top 130 is raised above the outer wall 123 of the locking member 120 and is exposed, and in the closed position, the disk top dispensing orifice 132 is arranged within the outer wall 123 of the locking member 120. The under surface of the disk top 130 includes a plug 133 that seals the dispense orifice 151 of the container 150 in the closed position by closing the open end of the passage 118a through the standing axle 118 of the main body 110. The seal of the main body 110 dispense orifice 118 is maintained by the disk seal 133 when closed in any axial position because the sealing features are round and concentric to the fixed dispense orifice standing axle 118. The disk top 130 is secured to the locking member 120 by way of two round projecting members 134 on opposing sides of the disk top 130 that are received in two opposing dimples 128 on the locking member 120. The disk top 130 is connected to the locking member 120 in such a manner that disk top 130 can be rotated on its pivot axis between the open and closed positions, and the disk top 130 is axially keyed to the locking member 120, so as the locking member 120 rotates axially from the locked to unlocked position, the disk top 130 also rotates axially along with the locking member 120. The disk top 130 can be secured to the locking member 120 in alternative manners that still allow the disk top 130 to pivot within the locking member 120 and rotate simultaneously with the locking member 120, such as by including the projections on the locking member 120 and the openings or dimples on the disk top 130, or by including a rod or pin(s) extending from or through the disk top 130 that is/are received by the locking member 120, or vice versa.
The dispensing container 150 may include a neck 152 or central opening through which the container substance can be dispensed out of the container 150. The neck 152 may have a cylindrical shape with a circular cross-section having a central axis formed therethrough. In the closed configuration (unlocked or locked), the standing axle 118 of the main body 110, the through-hole 122 of the locking member 120 and the sealing plug 133 are each in alignment. However, when secured to the dispensing container 150, these aligned elements of the closure system 100 are not aligned centrally with the central axis of the neck 152 of the dispensing container 150, that is, they are disposed off-center from the dispensing container 150 and rotate off of the central axis, as shown in
The protruding tab 131 of the disk top 130 comes to rest above a horizontal edge 114b the standing edge 114 of the main body 110 when the disk top closure system 100 is in a locked position, which impedes the pivot motion of the disk 130 from the closed/sealed position. Axial rotation of the locking member 120 and disk 130 from the locked to unlocked position causes the tab 131 to rotate away from the standing edge 114, so the disk 130 can be pivoted to the open/dispense angle.
The disk top closure system 100 includes the ability of the two-piece disk top functioning parts 120, 130 to rotate about a fixed axle dispense port 151 on a container 150, and to be automatically locked in a dispense disabled position, or rotated to a dispense enabled position after the cantilevered tab 125 is depressed. The inability of a small child to first depress the cantilevered tab 125, then rotate the locking member 120 to the open position contribute to the closure system 100 being “child-resistant.”
Further in the locked configuration, the protruding tab 131 of the disk 130 or a portion thereof, is disposed directly above and engages a horizontal edge 114b of the standing edge 114 projecting from the outer circumferential wall 112 the main body 110. The protruding tab 131 cannot be depressed in this configuration, such as to open the disk top 130 by pivoting the tab 131 downward and dispensing orifice 132 upward, as the standing edge 114 prevents such movement of the protruding tab 131 in the locked configuration. The disk top 130 is thus prevented from being opened to expose the dispensing orifice 132 and container orifice 151 in the locked configuration.
A cantilevered tab 125 of the rotating locking member 120 is disposed within a recess 113 of the outer circumferential wall 112 of the main body 110 when the closure system 100 is in the locked configuration. The recess 113 in the outer circumferential wall 112 can be substantially U-shaped, with the standing edge 114 on one side of the recess 113 and a vertical edge 115 on another side opposing a vertical portion 114a of the standing edge 114. At rest, the cantilevered tab 125 is biased outwardly (i.e., away from the center of the rotating locking member 120) and extends into the recess 113. An outwardly protruding edge 125a of the cantilevered tab 125 engages the vertical edge 115 of the recess 113. This engagement prevents the locking member 120 from being able to axially rotate in a direction that would disengage the protruding tab 131 of the disk 130 and the standing edge 114 and reposition the protruding tab 131 over the recess 113 of the outer circumferential wall 112 of the main body 110. The cantilevered tab 125 can be flexed inwardly by depressing the cantilevered tab 125 at or near the outwardly protruding edge 125a, which repositions the edge 125a within the outer circumferential wall 112 of the main body 110 and disengages the protruding edge 125a with the vertical edge 115. When the cantilevered tab 125 is disengaged from the vertical edge 115, the locking member 120 and connected disk top 130 can be rotated approximately 30 degrees from the locked configuration to the unlocked configuration. In order to unlock the disk-top closure system 100, the cantilevered tab 125 of the locking member 120 must be pressed and the locking member 120 rotated simultaneously.
In certain embodiments of the closure system 100, the main body 110 may comprise a pair of stopping ribs (not shown) arranged between the outer wall 112 and the inner wall 111, which are each configured to engage one of two vertical edges on the locking member 120, such as on the two ends of the arm 126. Each stopping rib is configured to engage a vertical edge when the locking member 120 is rotated in one of the two axial directions (i.e., in a first direction to unlock the closure system 100 and a second direction to relock the closure system 100), so that axial rotation of the flip-top member 120 relative to the closure body member 110 is constrained.
In the unlocked configuration, the locking member 120 and disk top 130 have been rotated from their position in the locked configuration, and the protruding tab 131 of the disk top 130 is disengaged from the standing edge 114 of the main body 110. The tab 131 of the disk 130 is repositioned to be entirely clear of the standing edge 114, and is disposed over the recess 113 in the outer circumferential wall 112 of the main body 110. The disk-top closure system 100 and the container 150 remain closed in this configuration and unable to dispense the contents of the container 150, but can be opened from this unlocked configuration. The protruding tab 131 of the disk 130 can be depressed to pivot the dispensing orifice 132 of the disk 130 vertically to expose the dispensing orifice 132.
When opened, the dispensing orifice 132 of the disk top 130 is exposed and the plug 133 of the disk top 130 is removed from the standing axle 118 of the main body 110. A continuous flow passage is formed from the container orifice 151, through the passageway 118a in the standing axle 118 and to the dispensing orifice 132 of the disk top 130 to allow dispensing the substance of the container 150.
The outer wall 123 of the locking member 120 comprises a clearance area 124 below the tab 131 of the disk top 130, so that the tab 131 can be depressed into the clearance area 124 without interference from the outer wall 123. The undersurface of the disk 130 includes an extension 135 that is positioned beneath the tab 131 and closes the clearance area 124 of the locking member outer wall 123 when the disk top 130 is closed, and prevents the formation of an open gap through the clearance area 124 in between the disk top 130 and the locking member 120. A depression 127 is formed in the floor 121 of the locking member 120 that is adjacent to the extension 135 of the disk 130 and is configured to receive the extension 135 when the disk top 130 is opened. The depression 127 is disposed in the slot 117 of the main body 110 when the locking member 120 is affixed to the main body 110.
To relock the disk-top closure system 100 and container 150, the disk top 130 can be closed by depressing the disk top 130 at or near the dispensing orifice 132, and the axial rotation of the locking member 120 and disk top 130 can be reversed to reposition the cantilevered tab 125 of the locking member 120 within the recess 113 of the main body 110. The cantilevered tab 125 is biased outwardly, such that when it is fully repositioned within the recess 113 of the main body 110, it extends back outwardly and the protruding edge 125a of the cantilevered tab 125 reengages the vertical edge 115 of the recess 113. This locking rotation repositions the tab 131 of the disk 130 over the standing edge 114 of the main body 110, at least in part, to prevent reopening of the disk top 130.
