U.S. Pat. No. 6,880,729 B2 to Gene Stull et al describes a secure lock for container packaging with a flexible retaining lip of various formations for sealing against material product flow distributions with the secure seal preventing tampering of, for example, a flexible walled container of material such as a medication, food stuff or art material. A resistant secure lock is provided which in one embodiment meets Federal Child Safety Standards providing a seal of flexible locking and unlocking which is resistant to a child's tampering. In one embodiment, a tamper resistant seal is formed for a squeezable container cap with a flexible hinging structure connecting a cap to a cap receptor base structure of a container to prevent a material product such as medicine from dispensing without disengaging the seal selectively to allow access to an aperture, yet with a directed flexion of a lip or head, the seal simply unsnaps from a tamper resistant state to release the flow of product through an aperture from a container.
U.S. Pat. No. 6,032,811 to Anthony Marconi describes a child resistant cap assembly that includes an outer cap member having a top wall and a substantially cylindrical side wall depending therefrom. On the exterior surface of the top wall is a key slot and an alignment aperture. An inner cap member for threadedly engaging a container neck is concentrically received within said outer cap member has a mark and key slot on its top wall. The outer cap member normally rotates independently of the inner cap member. When the outer cap member's alignment aperture registers with the mark on the inner cap member, the key slots are aligned allowing a key member to be inserted therethrough. Accordingly, the inserted key member is then rotated to simultaneously rotate the inner and outer cap. The top wall of the outer cap member also includes means for removably retaining the key thereon.
U.S. Pat. No. 6,029,835 to Stuart DeJonge describes a child resistant safety cap for containers that includes an outer cap, an inner cap, at least one retractable-extendable key arm and a biasing spring. The outer cap has a top and a sidewall with a plurality of openings for retraction and extension of the key arms therethrough, and the top has an engaging mechanism for engaging and disengaging the key arms. The inner cap is contained within the outer cap, has a sidewall and a top, with a slide mechanism for slideably attaching a plurality key of arms. The inner cap is a predetermined height less than the inside vertically slidable within the outer cap. The inner cap has a first vertical position away from the top of the outer cap wherein said engaging mechanism of the outer cap and the connecting mechanism of the plurality of key arms are disengaged, and the inner cap has a second vertical position, toward the top of the outer cap wherein the engaging mechanism and the connecting mechanism are engaged. The inner cap also has threading on its inside for screwing onto and off a thread container.

The top of the inner cap has a release key engagement on its outside, and the outside of the inner cap also has one way ratchets or ratchet blocks to permit engagement of the outer cap for rotating thereon, in a single, closing direction and preventing engagement of them for rotating them in a single, opposite, opening direction. The outer cap has a top and a sidewall having on its inside the other of a male attaching mechanism and a female attaching mechanism. The top of the outer cap has a release key bar with a key which is pivotable for 180° rotation so as to be engageable with the key arrangement of the inner cap so as to permit opening of the inner cap by rotation of the outer cap when the release key is engaged in the release key engagement.
U.S. Pat. No. 4,854,459 to Antonia DeJonge describes the present invention involves a container and cap which is generally childproof and may be rendered non-childproof permanently. The invention involves a container having a cylindrical neck at the top and threads molded about the exterior of the neck as well as an inner cap and outer cap. The inner cap has a top and a cylindrical side wall with threads molded on the inside of the side wall so as to mate with the threads of the container. The top or side of the inner cap has ratchet type segments on its outside and the outer cap has ratchet type segments on the inside of its top or side. The outer cap has a cylindrical side wall and is usually freely rotatable about the inner cap so as to be childproof. When in the childproof configuration as described, downward pressure is required by the user so as to engage the two ratchet type segments and thereby engage the two caps to permit opening. Further, the outer cap has an opening in its side wall at a lever near the bottom of the side wall of the inner cap and also has integrally attached thereto a flexible connector and stop. The flexible connector and stop are located so as to permit insertion of the stop into the opening so as to extend beyond the opening and push up the inner cap so as to permanently lock it into a position wherein the inner cap and outer cap ratchet type segments are permanently engaged. This renders the cap permanently non-childproof.
U.S. Pat. No. 4,555,035 to Eugene Davis describes a closure for a container. The closure is provided with a tunnel member into which any appropriate implement such as the handle of a teaspoon can be inserted when it is desired to manipulate the closure e.g. for opening. The provision of the tunnel member is of great assistance to people lacking in manual dexterity.
U.S. Pat. No. 4,333,589 to Randall Bush describes a child-resistant overcap for a pressurized container, such as an aerosol can, having a valve with an axially protruding discharge nozzle which must be depressed to actuate the valve for discharging the contents of the container. The overcap includes a valve guard moveable between an outer position in which a portion of the guard overlies the nozzle for preventing actuation thereof and an inner position in which the nozzle can be depressed. The overcap includes a resilient portion of the guard which biases the guard toward outer position and which must be overcome in order to move the guard to inner position and which returns the guard to outer position when the guard is released.
U.S. Pat. No. 4,325,497 to Ronald Ewald describes a child resistant spray through cover assembly for aerosol and similar containers. The cover assembly is adapted to be applied to a container having a conventional actuator button with a discharge outlet in which the actuator button discharges when it is moved axially toward the container. The cover assembly includes a housing which is adapted to fit over the actuator button and to be securely attached to the container. An opening is formed in the housing to allow the passage of spray discharge through the discharge outlet of the actuator button. A moveable flap is mounted on the housing and extends over the actuator button. The flap is moveable upon the application of force thereto by a finger of a user between a first position in which it is located out of actuating engagement with the actuator button and a second position in which it is in actuating engagement with the actuator button. A locking mechanism is provided to retain the flap in its first position. A finger engaging mechanism is provided for releasing the locking mechanism to permit the flap to be moved to its second position. A mechanism is provided on the flap for depressing the actuator button when the flap is moved to its second position. A spring arrangement is provided to return the flap to its first position and the locking mechanism to locking engagement with the flap when the application of force to the flap is discontinued so that the child resistant features of the cover assembly are automatically restored after the use and without any active participation of the user.
U.S. Pat. No. 3,831,804 to John Richard Focht describes an aerosol safety cap for an aerosol container including inner and outer telescoping members. The outer member includes dependant resilient locking means which snap under the interior of the annular bead of the mounting cup of the aerosol container to affix the outer member to the container. When the inner member is telescoped into the outer member, it prevents the resilient locking means from being inwardly deflected thereby preventing removal of the cap assembly from the container. Withdrawal of the inner telescopic member permits deflection of the depending locking means to permit removal of the cap from the container. The inner membrane cannot be withdrawn without the aid of a prying instrument such as a coin. The cap can be doubly locked by rotating the inner member with respect to the outer member with an instrument such as a coin into a position in which it can be pried upwardly.
Notwithstanding the prior art, the present invention is neither taught nor rendered obvious thereby.

Additional features, advantages, and embodiments of the invention may be set forth or apparent from consideration of the following detailed description, drawings, and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanation without limiting the scope of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate preferred embodiments of the invention and together with the detail description serve to explain the principles of the invention. In the drawings:
The invention relates generally to a child resistant container that is adapted to receive and to lock in a sprayer container with a top-positioned spray activator. The device is particularly beneficial as a retrofit child resistant container for potentially dangerous spray products to children, e. g., medicines, oven cleaners, etc. The device has a container main body for receiving the sprayer container, an inner cap to lock in the spray container and to allow the spray activator to rise up and down to be exposed, i.e., to be able to be depressed and released for spraying and stopping. The inner cap thus has a top seat(s) to allow keys to pass through. An outer cap acts as an over cap and can be removed and inverted to expose the push key(s). Once invented, the now downwardly facing push key(s) are fitted into the key slots that geometrically correspond to and receive the key(s). Also, because the outer cap has a downwardly extending tongue that conceals a corresponding opening in the present invention container main body, when the outer cap is inverted and the push rods are properly inverted and otherwise concealed, this spray window is open. When the outer cap is thus inverted and inserted, it is merely pushed downwardly to activate the spray activator for spraying.
Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views, the present invention is exemplified as follows:
Although
Spray container 20 has sidewall 4 and a top-positioned spray activator 6 with a nozzle. Preferably, container main body 10 is designed to receive spray container 20 with slight friction to prevent rotation of the spray container 20. On the inside of sidewall 3 of container main body 10, near the open top 5, is a first locking member 13 for receiving and locking inner cap 30 thereto. (This is shown as a receiving or female track, i.e. indented, and its counterpart on the inner cap is male or raised. However these could be reversed wherein the first locking member, on the container main body, would be a male, and its counterpart, the second locking member, on the inner cap, would be female.)
Spray container 20 is inserted into container main body 10 and then inner cap 30 is permanently attached to open top 5. Inner cap 30 includes a spray nozzle window (shown below in
Inner cap 30 has a sidewall 15 and a top 17 with spray activator key slots 23 and 25. Inner cap 30 also has a ledge 21 and a second locking member 19. When inner cap 30 is pushed into container main body 10, the male locking track, also known as second locking member 19, snaps into female receiving first locking member 13 of container main body 10, with ledge 21 fitting atop sidewall 3. Key slots 23 and 25 are of similar footprint to outer cap 40's keys 45 and 47 and are large enough to permit keys 23 and 25 to pose therethrough
Outer cap 40 has a central top 41, a sidewall 43 and a lower portion sidewall 55, as shown. Outer cap 40 has an open bottom 53. The inside lower of sidewall 55 of outer cap 40 is, in this embodiment, adapted to fit over inner cap 30 and to snuggly fit inner cap 20, but could be extended and adopted to fit onto container main body 10. Extending upwardly from the inside of top 41 of outer cap 40 are two push keys 45 and 47. These have the same footprint and are positioned to fit into push key slots 23 and 25 of inner cap 30 when outer cap 40 is inverted and positioned atop inner cap 30. Also, push keys 23 and 25 are of sufficient length such that when they are inserted and pushed into push key slots 23 and 25, they press down on spray container spray activator 6 to spray the contents of spray container 20. As mentioned above,
Once a user has completed a spray application from the spray container, the user removes the outer cap 40 from the top of the inner cap 30 and the container main body 10, inverts it, and then recaps the device to the original, closed, child resistant state, as shown in
Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
