Definitions

  • the invention relates to child-safe closures for containers, intended to be opened relatively easily by an adult but with much more difficulty by a young child.
  • Prior-art child safety feature designs typically employ a cap and container, which are separate from each other. It has been found desirable in the consumer and pharmaceutical industries to offer product packages with a unitary container and cap assembly (i.e., a flip-top lid). Since the cap and container are unitary, that is, in some way remain attached ⁇ even when opened) the cap cannot be misplaced when the container is opened. This promotes the maintaining of the container in a closed state at all times, except when contents are added or removed from the container.
  • An aspect of the invention is a container having a base, a lid that can be opened or closed, first and second latch portions, and a guard.
  • the base has an opening, and the lid is configured to cover the opening when closed.
  • One of the latch portions is associated with the base, and the other latch portion is associated with the lid.
  • the second latch portion is positionable to engage the first latch portion when the lid covers the opening, and is movable to disengage the first latch portion.
  • the guard is associated with the second latch portion and normally is in a blocking position keeping the second latch portion engaged with the first latch portion.
  • the guard is movable laterally, relative to the first latch portion, from its blocking position to a releasing position allowing the second latch portion to disengage the first latch portion.
  • the guard and second latch portion are relatively immovable in normal operation of the latch. In other embodiments the two are relatively movable parts in normal operation of the latch.
  • FIG. 1 is a perspective, schematic view of a container including the latching mechanisms of the present invention.
  • FIG. 2 is a schematic front elevation, with underlying parts shown in phantom section, of one embodiment of the invention according to claim 1 , sometimes referred to here as the Slide, Push Latch, and Lift Embodiment.
  • the latch is engaged and guarded.
  • Fig. 3 is a view similar to Fig. 2, showing the guard displaced laterally to the left. The latch is still engaged but not guarded against disengagement.
  • Fig. 4 is a section taken along section line A — 4 of Fig. 2.
  • Fig. 5 is a view similar to Fig. 4 of an alternative embodiment of the latch mechanism.
  • Fig. 6 is a view similar to Fig. 2 showing an alternative embodiment.
  • the latch is engaged and guarded.
  • Fig. 7 is a view similar to Fig. 3 of another embodiment of the guard.
  • Fig. 8 is a view similar to Fig. 2 of another embodiment sometimes referred to here as the Slide and Lift Embodiment. The latch is engaged and guarded.
  • Fig. 9 is a view similar to Fig. 8, but with the guard displaced laterally to an unlatched position.
  • Fig. 10 is a section taken along section line 10 — 10 of Fig. 8.
  • the present invention relates to a child safety feature for a unitary container that incorporates a sliding mechanism that prevents the movement of a latch or lid.
  • a sliding mechanism that prevents the movement of a latch or lid.
  • a "child-resistant" cap or closure for a container means that the cap or closure was tested in the following manner.
  • the child-resistant package cannot be opened by at least 85% of those children prior to a demonstration to them of the proper means of opening the package; and still cannot be opened by at least 80% of those children after they receive a demonstration of the proper means for opening the package.
  • at least 90% of those adults must be capable of opening the package.
  • the package is designed so that it may be re-closed, it can be re-closed by at least 90% of those adults but still cannot be opened by at least 85% of children to whom no demonstration of the proper method of opening the package has been given, nor by 80% of those children after a demonstration has been made.
  • the invention is a closed container used to house a product where it is desirable to provide a child safety feature.
  • the container can be opened and reclosed.
  • the container is filled with product and has an opening for product removal, which is smaller than the overall perimeter of the container.
  • the lid is opened.
  • there is a sliding element In order to provide the Child Safety Feature, there is a sliding element. In the closed position, the sliding element interfaces with a feature on the Lid that does not allow the lid to be opened.
  • the use of a sliding element allows for freedom in the aesthetic design of the container.
  • the location of the sliding element of the container can be, for example, on the front or the sides of the container as desired.
  • the feature that blocks the lid is located on the sliding element. The user actuates the slider at a distal end and not directly with the feature that blocks the movement of the Lid.
  • Position' blocks the movement of a feature on the lid.
  • a slider moves from one side to the other side.
  • the slider incorporates a means (spring, element) of returning the slider to the Home Position after being depressed.
  • the spring functionality is an integral part of the slider part design. As the slider is moved to one side or the other, it no longer blocks the movement of the feature on the lid, allowing it to be opened. The slider can be moved to one side of the other to allow right or left handed use.
  • the Lid has a flexible element, a latch, which is depressed to move past a locking feature of another part of the container.
  • a rib on the latch that blocks the movement when the sliding element is in the Home Position.
  • the sliding element is moved to one side, the rib is not obstructed, so the latch of the Lid can be pushed in to clear the feature on the other part of the container.
  • the sliding element is released it returns to the Home position.
  • the lid is simply closed and the latch deflects away the locking feature as it closes. The locking feature springs back, securing the Lid in the closed position.
  • the container 20 has an outside 22 and an inside 24, a base 26 having an opening 28 and a movable lid 30 configured to cover the opening 28 when closed.
  • the container 20 is shown latched closed in Figs. 1-4 by a latching mechanism 32 located in or near the fronts 34 and 36 of the base 26 and lid 30.
  • the latching mechanism 32 includes first latch portion 40, a second latch portion 42, and a guard 44.
  • the first latch portion 40 is associated with one of the base and the lid 30 (in the illustrated embodiment it is associated with the base).
  • the second latch portion 42 is associated with the other of the base and the lid 30 (in the illustrated embodiment it is associated with the lid 30).
  • the first and second latch portions 40 and 42 can be reversed, if desired.
  • the second latch portion 42 is positionable in the position shown in
  • the illustrated first latch portion 40 has a downward facing abutment 46 ("downward” here meaning facing away from the direction in which the lid 30 opens, and not necessarily referring to the orientation of the container relative to its surroundings).
  • the illustrated second latch portion 42 has an upward facing abutment 48 (“upward” here meaning facing in the direction in which the lid 30 opens, and not necessarily referring to the orientation of the container 20 relative to its surroundings).
  • the abutments 46 and 48 overlap and thus interfere, preventing the lid 30 from opening.
  • the second latch portion 42 has an inwardly projecting abutment or rib

  • the container 20 in addition to the latching mechanism 40, also has a secondary snap-fit latch 52 defined by a rib on an inner cover 54 of the container and a facing groove in a projection 56 of the lid 30.
  • this snap-fit latch 52 provides a seal between the base 26 and the lid 30 when the container 20 is closed.
  • the guard 44 is a separate part from the latch portions 40 and 42 in the embodiment of Figs. 1-4.
  • the guard 44 is associated with the second latch portion 42 and normally is in a blocking position, as shown in Fig. 2, keeping the second latch portion 42 engaged with the first latch portion 40.
  • the guard 44 is laterally elongated from left to right, generally "E" shaped as shown in Figs. 2 and 3, and has first and second laterally spaced portions or projections 60 and 62, here near the ends of the guard 44, and a central portion or projection 64.
  • a channel is defined in one of the base 26 and the lid 30 in which the guard 44 is slidable.
  • the channel is defined in the base 26 between the front wall 34 and an outside flange of the inner cover 54.
  • Fig. 5 shows an alternative embodiment 66 of the guard.
  • the guard 66 has an outwardly projecting abutment 68 located adjacent to the second latch portion 42 and having the same function as the abutment 64 shown in Fig. 4.
  • Figures 6 and 7 show additional embodiments of the guard and the cooperating structure mounted in the channel in which it slides.
  • the guard 72 includes lateral portions 60 and 62 exposed at the ends of the channel for pushing the guard laterally in either direction.
  • the guard 72 also has a pair of lugs 74 and 76 positioned to limit the travel of the guard 72 laterally by engaging the stops 78 and 80 at the normal extremities of travel of the guard 72.
  • the guard 72 has integral sliding fingers 82 and 84 that bear against the abutment fingers 88 and 90 mounted in fixed relation to the channel.

  • the fingers 82 and 88 and the fingers 84 and 90 respectively cooperate to normally center the guard 72, with the projection 64 and abutment 50 biased into at least partial registration, unless a sufficient force is applied to either lateral portion 60 or 62 to displace the projection 64 and the abutment 50 out of registration.
  • the guard 100 has similar construction to the guard 72 of Fig. 6, except that the sliding travel of the guard 100 is limited by the engagement of the slots 102 and 104 of the guard 100 with the pegs 106 and 108 fixed with respect to the slot in which the guard 100 slides.
  • the guard 100 is displaced to the left in Fig. 7, so the sliding finger 82 is out of contact with the abutment finger 88.
  • the sliding finger 84 has engaged and deformed the abutment finger 90 to the left, providing a bias tending to return the guard 100 to its centered position when the lateral portion 62 is no longer pushed to the left, as by a user disabling the guard 100 to open the container.

  • the second latch portion 42 is disengaged from the first latch portion 40 by displacing the abutment 48 of the second latch portion 40 inboard, or to the right in Fig. 4, as the lid 30 is raised.
  • This displacement of the abutment 48 can be executed, when opening the container, by pressing the exposed end of the latch portion 42 inwardly to clear the first latch portion 40 until the barb or cam 110 bears against the inside surface 112 of the latch portion 40.
  • the latch portion 40, 42, or both are made of resilient material, so no separate springs or other parts are needed to allow the latch to function. This is conventional construction for molded plastic parts, for example.
  • the second latch portion 42 is movable (when the guard 44 is displaced, as shown in Fig. 3) to disengage the first latch portion 40.
  • the portion of the second latch portion 42 defining the abutment 48 is movable to the right as shown in Fig. 4.
