The integrity of closures on bottles and other container has always been a concern to consumer goods manufacturers. Leakage of product during shipping can be a costly problem. Also, leakage of product in the hands of consumers is not conducive to repeat purchase.
Leakage concerns are magnified in the current world of e-commerce. It is somewhat easier to ensure intact shipment of large numbers of bottles together than it is to secure the product form leakage during shipment of individual bottles from e-commerce retailers or even for e-commerce shipment from the manufacturer. Likewise, transport of a container by a consumer after she has opened it can be problematic and result in product leakage.
A popular type of closure for consumer goods such as shampoos, body washes, skin creams, etc. is the disc closure wherein a disc at the top of the closure rotates between an open and a closed position. With this type of closure care needs to be taken to ensure that the disc does not rotate open during shipment.
Various types of disc and other type closures are described in the literature. Puderbach et al. WO2017/046186 discloses a dispensing closure comprising a base and an actuator disc pivotally mounted on the base with two pivots. A tamper evident strip 24 is frangibly connected to the lid sidewall. The strip prevents movement of the lid but the act of pressing down on depression 25 causes the strip to be broken away from the sidewall. The strip is automatically separated from the lid as it is forced down against the notch.
Oder U.S. Pat. No. 5,709,318 discloses a toggle dispensing lid having an integral locking switch attached to the closure body. The integral locking switch includes at least two living hinges so that it may be moved between locked and unlocked positions thereby permitting movement of the dispensing lid between closed and product dispensing positions. Lay WO 95/16633 discloses a toggle action dispensing closure. A cam 98 frictionally engage a wall of closure and serves to stabilize an actuator as it is pivoted. Frictional engagement of the cam maintains the actuator in the titled, open position. A post 110 is provided to prevent accidental movement of the actuator to the open position. A force equal to or greater than a predetermined force, such as that applied by a consumer to open the closure, will drive a wall against post 110 with a force sufficient to sever the abutment.
Englert et al. WO2004071882 discloses a disc top dispensing closure having an actuator which is pivotable about a pivot axis. The actuator is pivotable about a locked position and an unlocked position. A tab 80 and a recess 82 cooperate with each other so that when they are aligned the actuator is pivotable open but when they are not aligned the actuator is not pivotable between the open and closed position. The consumer rotates the actuator between the unlocked position wherein the tab and recess are aligned and the locked position. Kaufman et al. WO2004/054921 is similar.
Rosenthal et al. U.S. Pat. No. 6,152,329 discloses a closure cap having a top plate pivotally attached to a body, for movement between open and closed positions. A locking lever is provided having a fulcrum so that the upper end of the locking lever can be located in the path of movement of the top plate when it is closed to thereby obstruct movement of the top plate to the open position.
Wood et al. U.S. Pat. No. 6,029,866 discloses a dispensing structure having a pivoting actuator. The actuator may include a rearwardly extending angled cam 92 for engaging a protuberance 93. The cam slides against the protuberance on the peripheral wall and serves to stabilize the actuator as it is being pivoted. The cam provides a frictional engagement to maintain the actuator in the tilted, open position.
Gross et al. U.S. Pat. No. 5,314,093 discloses a toggle action dispensing closure having a locking ring which in one position in which an abutment member lies under the actuator engaging a tab to prevent pivoting of the actuator to the open position and the locking ring including a second position wherein the locking ring abutment member is clear of the actuator engagement tab to permit pivoting of the actuator to the open position.
Sawicki U.S. Pat. No. 5,622,284 discloses a child resistant cap having a partial top wall preventing one from impressing effective opening forces on a press to open section of the actuator except using a probe acting through a restricted opening in the top wall. Among dispensers disclosing containers having a closure and a fastener are Tacker et al. USD749,363, Wahl US2014/0034644, and Lane, USD690,559.
Vollers WO 022795 discloses a hinged disk top closure with a locking device.
Kaufman et al. U.S. Pat. No. 6,896,160 discloses a pivotable disc top dispensing closure. The actuator is rotatable between a locked position and an unlocked position.

The invention is directed to a pivotable disc closure actuator, to a closure including the actuator and to the closure combined with a bottle or other container. The actuator includes a closing surface comprising a product dispensing opening at a front thereof, at least two pivots on the closing surface, an extension panel extending from a peripheral wall of the closing surface and having a locking and an unlocking position, the pivots being intermediate the product opening and the extension panel, and the extension panel having a latch member extending inwardly toward the closing surface when the extension panel is in the closed position.
The closing surface of the adaptor is generally circular, the opening is within a first arc of 120 degrees at the front of the closing surface, the extension panel is within a second arc of 120 degrees at a rear end of the closing surface, and the pivots are each within third and fourth arcs of 60 degrees each on opposite sides of the closing surface, the third and fourth arcs being intermediate the first and second arcs.
In accordance with one aspect of the invention, the pivotable disc closure actuator further includes a latch retainer for securing the panel extension and keeping the closing surface in the closed position. The actuator may comprise an aperture or indentation for receiving the latch to assist in retaining the latch. The extension panel is preferably attached to the actuator using a living hinge.
The actuator will generally be combined with a closure base which includes an opening suitable for receiving the pivotable adaptor, at least two surfaces on which the pivots can rest when the closing surface is received within the closure base, the combined pivotable closure and closure base further comprising a latch retainer on one or both of the pivotable closure and closure base suitable for receiving and securing the latch member when the extension panel is in the closed position.
The closure base of the invention may include a cut out or opening in an outer wall and the extension panel may rests on a surface of the outer wall cut out or opening when the actuator is in the locked position.
For a more complete understanding of the above and other features and advantages of the invention, reference should be made to the following detailed description of preferred embodiments and to the accompanying drawings.
Closure actuator 10 comprises a disc closing surface 12 having a generally circular finger indentation 20. The actuator 10 includes a closing surface comprising a product dispensing opening 50 at a front thereof, An upper skirt 14 depends from surface 12 and a tapered lower skirt 16 depends from upper skirt 14. Rounded pivot member 18 extends outwardly from upper and lower skirts 14, 16; a second rounded pivot (not shown) extends from outwardly from the opposite side of the actuator.
Extension panel 22 is connected to upper skirt 14 adjacent finger indentation 20 by living hinge 15. In the unlocked position seen in
Skirt 16 includes latch receiving/retaining aperture 16 beneath hinge 15, which aperture is illustrated in a generally semicircular shape.
Lower closure body 32 is illustrated as generally cylindrical comprising a generally cylindrical outer wall 31 and includes on its inner wall 33 pivot-receiving semicircular depression 30. A second pivot receiving depression (not shown) is located on the opposite inner wall. Inner wall 33 snugly receives tapered lower skirt 16. One or more tabs 60 facilitate a friction fit for the adaptor with inner wall 33 to assist in retaining the actuator 10 in the open position. Lower body 32 includes circular product passage 34 for conveying product from a bottle (not shown) to the exterior of the closure. Pivot members 18 on actuator 10 pivot in depressions 30 to permit the actuator to pivot between a closed position wherein product cannot be dispensed from the package (seen in
Lower closure body 32 outer wall 31 includes a generally semicircular cutout 40, which may alternatively be an opening, adjacent depression 20 to accommodate extension panel 22, as will be explained below.
As mentioned above, inadvertent opening of closures and attendant product leakage pose a special problem for shipping products ordered through e-commerce. The closure of the invention solves this problem by including extension panel 22, living hinge 15 and latch 24. When it is desired to permit the opening of the actuator, extension panel 22 is in the open position seen in
When it is desired to ship or otherwise transport the container, extension panel 22 is pressed downwardly, rotating on living hinge 15, so that latch 24 passes into aperture 26 and retaining tab 28 is disposed interior of the upper and/or lower skirts and keeps the extension panel in the locked position. As can be seen in
When it is desired to dispense product from the container, extension panel 22 is lifted upwardly thereby removing latch 24 from aperture 26, so that actuator 10 is in the position shown in
