DETAILED DESCRIPTION

[0035] The container system has significant benefits across a broad spectrum of endeavors. It is the Applicant's intent that this specification and the claims appended hereto be accorded a breadth in keeping with the scope and spirit of the disclosure despite what might appear to be limiting language imposed by the requirements of referring to the specific examples disclosed. To acquaint persons skilled in the pertinent arts, a preferred embodiment that illustrates the best mode now contemplated for putting the container system into practice is described herein by, and with reference to, the annexed drawings that form a part of the specification. The exemplary embodiment is described in detail without attempting to describe all of the various forms and modifications in which the container system might be embodied. As such, the embodiments described herein are illustrative, and as will become apparent to those skilled in the arts, may be modified in numerous ways within the scope and spirit of the disclosure.

[0036] Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term by limited, by implication or otherwise, to that single meaning.

[0037] Various embodiments are described herein and as depicted in the drawings. It is expressly understood that although the figures depict container systems, caps, and methods and systems for using the same, the present disclosure is not limited to these embodiments.

[0038] Referring now to FIG. 1, a storage system is shown that comprises a container 2 or bottle and a combination cap and dropper 4. The container 2 is contemplated as comprising a bottle of various materials, sizes, etc. A glass bottle is shown, but containers 2 of the present disclosure are not limited to any particular material or size. A dropper 4 is provided that comprises a pipette 6, a cap 8 and a bulb 10. The cap 8 is contemplated as comprising internal threads 12 that correspond and mate with external threads 14 on the container 2. The cap and dropper 4 provide the dual purposes of closing or securing the bottle and providing a dispensing apparatus. When the cap 8 is secured to the bottle it provides a closure mechanism for the bottle. When the cap 8 is removed from the bottle, the bulb 10 and pipette 6 are operable to serve as a dropper-type dispensing apparatus. Fluid (including but not limited to air) can be purged from the pipette by applying a force to the bulb 10. The bulb 10 preferably comprises an elastic element with an inherent restoring force. Accordingly, removing a force from the bulb 10 provides a suction force or pressure differential that is operable to draw fluid (including but not limited to liquid from the container 2) into the pipette. The fluid can then be dispensed as desired by applying a force to the bulb. This process is repeatable.

[0039] The embodiment of FIG. 1 is a conventional system. A first action is required in order to remove the cap 8 and pipette 6 from the container 2. Additional, subsequent action is required to then load the pipette 6 and draw fluid into the pipette 6.

[0040] FIG. 2 depicts an embodiment of the present disclosure wherein loading of the pipette is provided in an automated or self-loading process. As shown in FIG. 2, a container system 20 is provided that comprises a container 22 and a closure member 24. The closure member 24 comprises a combined cover and dispensing device as will be shown and described. The closure member 24 comprises a pipette 28 for selectively dispensing a liquid (for example). A button 30 is provided that covers and communicates with a bulb (not shown in FIG. 2) and an outer cap 26. The closure member 24 preferably comprises safety features including, for example, child-lock features as shown and described herein.

[0041] FIG. 3 is an exploded perspective view of a container system 20 according to an embodiment of the present disclosure with various components arranged along a longitudinal axis 33. As shown, a container 22 is provided. A closure member is provided that comprises a combination lid and dispensing device. The lid and dispensing system comprises a pipette 28 is provided that is operable to extend into the container 22 at least when the device is in an assembled or closed position. The pipette comprises an internal volume, a tapered distal end and an open proximal end. The pipette 28 is operable to house and store fluid and dispense the same in a controlled and predictable manner.

[0042] An outer cap 26 is provided that is operable to communicate with additional components as shown and described herein. A bulb 34 is disposed partially within the outer cap, and the bulb 34 is actuated by a button 30 which is accessible to a user. The button 30 in this embodiment has both a ridge 31 and a protrusion 32 extending from an outer surface. An inner cap 36 is provided and is disposed at least partially within the outer cap in an assembled state. A threaded member 38 is provided that is operable to communicate with threads of the bottle 22. The threaded member 38 comprises teeth at a proximal end thereof to selectively communicate with the inner cap 36 and related components. In the depicted embodiment, an axial or longitudinal force must be provided to place the inner cap 36 in communication with the threaded member 38 and impart a rotation force. This arrangement provides a safety or “child-lock” feature wherein rotation of the outer cap 26 (for example) alone will not result in an un-threading or removal of the closure member from the bottle. A rotational motion must be provided in combination with an axial or longitudinal force in order to remove the closure and dispensing device from the container 22. Seals 40, 42 are provided to secure the bulb 34 to the pipette 28 and to provide a secure closure of the container 22.

[0043] FIG. 4 is an elevation view of a container and dispensing system 20 according to one embodiment of the present disclosure. Various components have been removed in FIG. 4 for illustrative purposes and to assist in depicting the safety features of the device. As shown, the system 20 comprises a container 22 and a closure member. The closure member comprises a plurality of components including, for example, an inner cap 36 and a threaded member 38. A button 30 protrudes from the inner cap 36 and is operable to provide a force upon a bulb (not shown in FIG. 4, but see 34 in FIG. 3) to operate a pipette. As shown in FIG. 4, the teeth 41 of the inner cap 36 are provided in force-transmitting communication with the teeth 43 of the threaded member 38. In this arrangement, a force applied to the outer cap and/or inner cap 36 is operable to impart force and rotation upon the threaded member 38 and thus secure or remove the cap from the container 22. In a second configuration (not shown in FIG. 4), the inner cap 36 is spaced apart from the threaded member 38 such that the teeth of the related features are not in contact with one another and rotation of the outer cap and/or inner cap does not apply force to the threaded member 38. Additionally, the outer cap (26 in FIG. 3) provides a shroud or cover member that substantially prevents contact with the threaded member 38 such that the threaded member 38 cannot be rotated independently of the outer cap and/or inner cap 36.

[0044] FIG. 5 is a cross-sectional elevation view of a container and dispensing system according to one embodiment of the present disclosure. As shown, a container 22 is provided that comprises an internal volume for storing contents. A closure member is provided that comprises a pipette 28. The pipette 28 extends into the internal volume of the container at least when the system is provided in a closed position. A tapered distal end of the pipette is preferably provided at or proximal to a lowermost portion of the internal volume of the container 22 where it is capable of drawing fluid regardless of a fill level of the container 22.

[0045] In the assembled state shown in FIG. 5, the closure and dispensing member comprises a button 30 that is operable to contact a bulb 34 to operate the pipette 28. The button 30 is operable to control and actuate the bulb 34 is a conventional manner. Specifically, the button 30 may be selectively depressed by a user to purge fluid and pressure from the bulb 34 and pipette 28. Releasing the button 30 allow the bulb 34 to restore its original position and draw fluid (e.g. air, liquid, oil, etc.) into the pipette. Additionally, and as will be shown and described in more detail herein, the interaction of various components of the present disclosure are operable to “auto-fill” a pipette 28 by transferring force to the bulb 34. In some embodiments, a twisting or threading motion of the threaded member 38 and outer cap 26 transfers a force to the bulb 34 such that the system is closed and the bulb is depressed. This action purges the bulb 34 and pipette 28 of contents. When the cap is unthreaded or removed, force or pressure is removed from the bulb, thereby allowing it to regain its original unbiased position and create a pressure differential that “automatically” draws contents from the container 22 into the pipette 28. In contrast with known devices, embodiments of the present disclosure do not need to be opened and then subsequently filled or charged.

[0046] FIG. 6 is a cross-sectional elevation view of an embodiment of the present disclosure and wherein the outer cap 26 has been removed for illustrative purposes. As shown in FIG. 6, a system is provided that comprises a container 22, a pipette 28, a bulb 34, a threaded member 38, an inner cap 36, and a button 30 as described with respect to FIG. 5. The outer cap 26 of various embodiments of the present disclosure comprises a ramp or cam 44. The cam 44 is operable to impart a force upon additional components and to convert a rotational motion of the outer cap 26 to a linear force to be applied to the bulb 34 (for example). The button 30 of the depicted embodiment comprises a ridge (see 31 in FIG. 3) extending from an outer surface of the button. As the outer cap 26 rotates, the cam 44 progressively drives the button 30 downward by contact with the ridge, until the button is fully depressed against the pliable bulb 34. This action evacuates excess fluid (e.g. air) from the pipette 28. The button preferably remains in the depressed position while the lid is on the container. As the lid is removed and the outer cap 26 rotates in the opposite direction, contact between the cam is withdrawn and the bulb 34 returns to its expanded position. Fluid is thus drawn from the container 22 into the pipette 28. This relationship automatically “loads” the pipe with fluid as the lid is removed from the container. Accordingly, the dispensing device including the pipette is ready for use as soon as it is removed from the container 22.

[0047] In various embodiments, it is contemplated that the outer cap 26 is secured to the inner cap 36. Accordingly, rotation and linear movement of the inner cap 36 is achieved whenever the same motion is provided to the outer cap 26. In various embodiments, the inner cap 36 is not accessible to a user and the movement of the inner cap is achieved by contacting and manipulating the outer cap 26.

[0048] FIG. 7 is an exploded cross-sectional elevation view of an embodiment of the present disclosure. As shown, various components and features have been separated for illustrative purposes. As shown, an outer cap 26 is provided. The outer cap 26 comprises a cam 44 that is operable to contact and apply force to additional components when the outer cap 26 is rotated. In some embodiments, the cam 44 applies a force and drives a button 30 is disposed around and in communication with a bulb 34. An inner cap 36 is provided within the outer cap 26. The inner cap comprises at least one slot 37 in which a protrusion (see 32 in FIG. 6) of the button 34 is disposed such that the button is capable of translating axially or longitudinally with respect to the inner cap 36. The inner cap 36 is moveable relative to a threaded member 38. The inner cap 36 and the threaded member 38 comprises teeth such that when these components are pressed together, rotation of the threaded member 38 is enabled.

[0049] In some embodiments, the inner cap 36 is biased upwardly or away from the threaded member 38. In certain embodiments, a coil or leaf spring is provided as being provided to bias and separate the inner cap and the threaded member and prevent contact between these two elements unless and until a force is applied. In other embodiments, the inner cap is not biased by a biasing element (e.g. spring), but a force is required to mate the two elements and achieve rotation of the threaded member 38.

[0050] In some embodiments, the outer cap 26 and the inner cap 36 are in communication such that they are rotationally fixed relative to one another. The inner cap 36 is preferably displaceable in an axial or longitudinal direction relative to the outer cap 26 but are rotationally fixed such that they co-rotate (when the outer cap is rotated, for example). The threaded member 38 is rotatable within and relative to the outer cap 26 at least when the teeth of the inner cap 36 and the threaded member are not engaged. Upon placing the inner cap 36 in communication with the threaded member 38, the outer cap 26, the inner cap 36 and the threaded member 38 are operable to rotate together. As previously discussed, the cam 44 of the outer cap 26 contacts and drives the button 30 which is axially or longitudinally displaceable within the inner cap 36. This displacement allows for a threaded closing of the container and simultaneous purging and depressing of the bulb 34. The system is thus provided in a closed position with the bulb being depressed. Reverse rotation is then provided to open the container, whereupon external pressure is removed from the bulb 34, allowing the pipette 28 to draw fluid in such that the device is automatically prepared for use.

[0051] Thus, embodiments of the cap system described herein can function in various modes of operation. In a manual mode of operation, a longitudinal force acts on the button 30 and drives the button 30 in a first direction along the longitudinal axis 33 (see FIG. 3) into the pliable bulb 34 to compress the pliable blub 34 and drive any fluid out of the pipette 28 and into the container 22. When the longitudinal force is removed from the button 30, the pliable bulb 34 expands, which draws in fluid from the container 22 into the pipette 28. The expansion of the pliable bulb 34 also moves the button 30 in a second direction along the longitudinal axis 33 away from the other components of the cap system. In this sense, direct, manual actuation of the button 30 operates the pliable bulb 34 and pipette 28 like an eyedropper.

[0052] The cap system may also function in an auto-loading mode of operation. In this mode, a longitudinal force acts on the outer cap 26, which drives the outer cap 26 into the inner cap 36 along the longitudinal axis 33 and also causes the teeth of the inner cap 36 to engage the teeth of the threaded member 38. Next, a rotational force acts on the outer cap 26. In the depicted embodiment, the rotational force acts in a clockwise direction about the longitudinal axis 33 when viewed from above. The rotational movement of the outer cap 26 drives a cam of the outer cap 26 into a ridge of the button 30, causing the button 30 to move along the longitudinal axis 33 in a first direction to compress the pliable bulb 34 and drive any fluid out of the pipette 28 and into the container 22. The rotational movement of the outer cap 26 is also translated to the inner cap 36, which, through engagement of the teeth, causes the threaded inner surface of the threaded member 38 to screw onto the threaded outer surface of the container 22. Once in this closed position, the container 22 and cap system can be stored with the pliable bulb 34 purged.

[0053] When use of the cap system and the contents of the container 22 is desired, a longitudinal force again acts on the outer cap 26 for teeth engagement, and a rotational force acts on the outer cap 26. This time, the rotational force acts in a counterclockwise direction about the longitudinal axis 22 when viewed from above. Thus, the threaded member 38 is unscrewed from the container 22, and the cam of the outer cap 26 backs off of the ridge of the button 30. This allows the pliable bulb 34 to expand and draw in fluid from the container 22 into the pipette 28 as the cap system is removed from the container 22. Thus, the pipette 28 is automatically loaded with fluid as the cap system is removed from the container 22.

[0054] The description of the container system has been presented for purposes of illustration and description but is not intended to be exhaustive or limiting of the container system to the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments described and shown in the figures were chosen and described in order to best explain the principles of the container system, the practical application, and to enable those of ordinary skill in the art to understand the container system.

[0055] While various embodiments have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. Moreover, references made herein to “the container system” or aspects thereof should be understood to mean certain embodiments of the container system and should not necessarily be construed as limiting all embodiments to a particular description. It is to be expressly understood that such modifications and alterations are within the scope and spirit of the present disclosure, as set forth in the following claims.
