Description

Summary of the Invention

[0001] In one or more aspects, a container system includes: (I) a container comprising (A) an upper portion, (B) a bottom portion, and (C) at least one intermediate portion extending between the upper portion and the bottom portion, wherein the upper portion, the bottom portion, and the at least one intermediate portion at least partially form the interior of the container; and (II) a tubular member coupled to the upper portion, the tubular member comprising (A) a longitudinal tubular portion coupled to the upper portion of the container, (i) the longitudinal tubular portion at least partially extends from the upper portion towards the bottom portion, and (ii) the longitudinal tubular portion includes a flow direction having a vector component oriented in a direction away from the upper portion and towards the bottom portion; (B) an expansion tubular portion at least partially extending towards the upper portion, (i) the expansion tubular portion includes a flow direction having a vector component oriented in a direction away from the bottom portion and towards the upper portion, and (ii) the expansion tubular portion includes a maximum cross-sectional flow area taken perpendicular to the flow direction; and (C) a flow direction conversion tubular portion positioned between the longitudinal tubular portion and the expansion tubular portion, (i) the flow direction conversion tubular portion includes a plurality of flow directions including a first flow direction and a second flow direction, (a) the first flow direction includes a vector component oriented in a direction away from the upper portion and towards the bottom portion, and (b) the second flow direction includes a vector component oriented in a direction towards the upper portion and away from the bottom portion, (ii) the flow direction conversion tubular portion includes a cross-sectional flow area taken perpendicular to the second flow direction, and (iii) the maximum cross-sectional flow area of the expansion tubular portion is larger than the maximum cross-sectional flow area of the flow direction conversion tubular portion. The container system further includes an acoustic emitter, and the longitudinal tubular portion is coupled to the acoustic emitter. Thus, the first flow direction and the second flow direction of the flow direction conversion portion are different by at least 60 degrees. Thus, the flow direction of the longitudinal tubular portion and the first flow direction of the flow direction conversion portion are different by at least 30 degrees. Thus, the expansion tubular portion includes a plurality of cross-sectional flow areas taken perpendicular to the flow direction of the expansion tubular portion, and the size of at least a part of the plurality of cross-sectional flow areas increases based on an increase in the distance from the flow direction conversion portion along the flow direction of the expansion tubular portion. Thus, the longitudinal tubular portion includes a portion having a constant cross-sectional flow area taken perpendicular to the flow direction of the longitudinal tubular portion.Therefore, the longitudinal tubular portion includes a portion having a constant inner diameter taken perpendicular to the flow direction of the longitudinal tubular portion. Therefore, the longitudinal tubular portion includes a volume, the direction-changing tubular portion includes a volume, the expanding tubular portion includes a volume, and the sum of the volume of the longitudinal tubular portion and the volume of the direction-changing tubular portion is larger than the volume of the expanding tubular portion. Therefore, the direction-changing tubular portion includes a volume, the expanding tubular portion includes a volume, and the volume of the expanding tubular portion is larger than the volume of the direction-changing tubular portion. Therefore, the plurality of flow directions of the flow direction-changing tubular portion includes a third flow direction equal to the flow direction of the flow direction-expanding tubular portion, the flow direction-changing tubular portion includes a maximum cross-sectional flow area taken perpendicular to the third flow direction, the expanding tubular portion includes a minimum cross-sectional flow area taken perpendicular to the flow direction of the expanding tubular portion, and the maximum cross-sectional flow area taken perpendicular to the third flow direction of the direction-changing and expanding tubular portion is smaller than the minimum cross-sectional flow area of the expanding tubular portion. Therefore, at least one intermediate portion includes a geometry forming at least one curve. It further includes a fluid outlet fluidly connected and coupled to at least one intermediate portion. It further includes a fluid outlet fluidly connected and coupled to the upper portion. Therefore, the container further includes a lid, and the lid is removably coupled to the upper portion of the container. Therefore, the flow direction of the longitudinal tubular portion is not equal to any of the plurality of flow directions of the flow direction-changing tubular portion.

[0002] In one or more aspects, a container system includes: (I) a container including (A) an upper portion, (B) a bottom portion, and (C) at least one intermediate portion extending between the upper and bottom portions, the upper, bottom, and at least one intermediate portion at least partially forming the interior of the container; and (II) a tubular member coupled to the upper portion, the tubular member including (A) a longitudinal tubular portion coupled to the upper portion of the container, the longitudinal tubular portion including (i) extending at least partially from the upper portion toward the bottom portion, (ii) a flow direction having a vector component oriented away from the upper portion and toward the bottom portion, and (iii) a minimum cross-sectional flow area taken perpendicular to the flow direction; and (B) an expansion tubular portion extending at least partially toward the upper portion, the expansion tubular portion including (i) a flow direction having a vector component oriented away from the bottom portion and toward the upper portion, (ii) a maximum cross-sectional flow area taken perpendicular to the flow direction, and (iii) the minimum cross-sectional flow area of the longitudinal tubular portion being less than the maximum cross-sectional flow area of the expansion tubular portion. Thus, the longitudinal tubular portion includes a portion having a constant cross-sectional flow area taken perpendicular to the flow direction of the longitudinal tubular portion. Thus, the longitudinal tubular portion includes a volume, the direction-changing tubular portion includes a volume, the expansion tubular portion includes a volume, and the sum of the volume of the longitudinal tubular portion and the volume of the direction-changing tubular portion is greater than the volume of the expansion tubular portion.

[0003] In one or more aspects, a container system includes: (I) a container including (A) an upper portion, (B) a bottom portion, and (C) at least one intermediate portion extending between the upper and bottom portions, the upper, bottom, and at least one intermediate portion at least partially forming the interior of the container; and (II) a tubular member coupled to the upper portion, the tubular member including (A) a longitudinal tubular portion coupled to the upper portion of the container, (i) the longitudinal tubular portion at least partially extending from the upper portion toward the bottom portion, (ii) the longitudinal tubular portion including a flow direction having a vector component oriented in a direction away from the upper portion and toward the bottom portion, and (iii) the longitudinal tubular portion including a minimum cross-sectional flow area taken perpendicular to the flow direction; and (B) an expansion tubular portion at least partially extending toward the upper portion, (i) the expansion tubular portion including a flow direction having a vector component oriented in a direction away from the bottom portion and toward the upper portion, (ii) the expansion tubular portion including a maximum cross-sectional flow area taken perpendicular to the flow direction, and (iii) the maximum cross-sectional flow area of the longitudinal tubular portion being less than the minimum cross-sectional flow area of the expansion tubular portion.

Best Mode for Carrying Out the Invention

[0007] In the following embodiments for carrying out the invention, the accompanying drawings forming a part thereof are referred to. In the drawings, like reference numerals generally identify like components unless otherwise indicated by context. The exemplary embodiments described in the embodiments for carrying out the invention, the drawings, and the claims are not intended to be limiting. Other embodiments may be utilized and other changes may be made without departing from the spirit or scope of the subject matter presented herein.

[0008] Referring to FIG. 1, there is shown a side cross-sectional view of a conventional container system 100 in an upright position. In an embodiment, the conventional container system 100 is shown to include an emitter-dispenser assembly 102 and a container 104. In an embodiment, the emitter-dispenser assembly 102 is shown to include an acoustic emitter 102a, a stopper 102b, a tubular member 102c, and a tubular member 102d. In an embodiment, the container 104 is shown to include a neck 104a containing ambient air A1, a portion of a liquid A3, and an ambient liquid level A2 therebetween, and a body 104b containing a portion of the liquid A3.

[0009] Referring to FIG. 2, there is shown an enlarged side cross-sectional view of a portion of the conventional container system 100 in an upright position, where the upper portion of the tubular member 102d contains ambient air A1 and the lower portion of the tubular member 102d contains a portion of the liquid A3.

[0010] Referring to FIG. 3, there is shown a side cross-sectional view of the conventional container system 100 in a first inclined position, and as a result, when the liquid A3 exits the container 104 through the tubular member 102c as shown by the dispensed liquid A6, a contained liquid level A5 of the liquid A3 occurs between the body 104b and the trapped air A4.

[0011] Referring to FIG. 4, there is shown an enlarged side cross-sectional view of a portion of a conventional container system 100 in a first inclined position, where bubbles A7 from the ambient air A1 around the tubular member 102d pass through the liquid A3, over the liquid level A5 of the enclosed liquid, and into the enclosed air A4, which better shows this. When a plurality of bubbles A7 are generated, a constantly fluctuating flow of the ambient air A1 within the tubular member 102d occurs, whereby the acoustic generation of the acoustic emitter 102A may constantly fluctuate as compared to the stable acoustic generation of the acoustic emitter 102A when a steady flow of the ambient air A1 is passing through the acoustic emitter 102A.

[0012] Referring to FIG. 5, there is shown a side cross-sectional view of a conventional container system 100 in a second inclined position, where the liquid A3 further exits the tubular member 102c as indicated by the dispensed liquid A6, the liquid level A5 of the enclosed liquid is below the end of the tubular member 102d inside 104a, and since none of the liquid A3 is present inside the tubular member 102d, both the fluctuating flow of the ambient air A1 within the tubular member 102d and the fluctuating acoustic generation of the acoustic emitter 102A are prevented.

[0013] Referring to FIG. 6, there is shown a side cross-sectional view of the enhanced container system 10 in an upright position and with the liquid in an empty state. In an embodiment, the enhanced container system 10 is shown to include a tubular member 12, a container assembly 14, and an acoustic emitter 16. In an embodiment, the tubular member 12 is shown to include a longitudinal portion 12a, a direction-changing portion 12b, and an expansion portion 12c. In an embodiment, the removable lid 14a, the container assembly 14 is shown to include a removable lid 14a, an upper portion 14b, an intermediate portion 14c, a handle portion 14d, a bottom portion 14e, an intermediate portion 14f, and a fluid outlet 14g. In an embodiment, it can be fastened by gravity, friction, screwing, etc. As shown, the intermediate portion 14c and the intermediate portion 14f extend between the upper portion 14b and the bottom portion 14e to form a bowl-like shape, but in other embodiments, the container assembly 14 can have other curved geometries such as cylindrical, rectangular, and / or linear geometries. As shown, the fluid outlet 14g is coupled to the upper portion 14b and the intermediate portion 14f, but in other embodiments, the fluid outlet 14g can be coupled to the removable lid 14a. In an embodiment, the tubular member 12 is shown coupled to the acoustic emitter 16, and the acoustic emitter 16 is both shown coupled to the upper portion 14b of the container assembly 14. In other embodiments, the tubular member 12 can be coupled to the acoustic emitter 16, and the acoustic emitter 16 can both be coupled to the removable lid 14a.

[0014] Referring to FIG. 7, there is shown an enlarged side cross-sectional view of a first portion of the enhanced container system 10 in an upright position and with the liquid in an empty state.

[0015] Referring to FIG. 8, there is shown an enlarged side cross-sectional view of a second portion of the enhanced container system 10 in an upright position and with the liquid in an empty state.

[0016] Referring to FIG. 9, there is shown a side cross-sectional view of the enhanced container system 10 in an upright position and with the liquid in an empty state, showing the flow direction of the tubular member 12. These flow direction indicators show how the tubular member 12 is constructed to have various flow directions, and the "flow direction" is a term used herein to describe the geometry of the structure of the tubular member 12, regardless of the actual fluid flow rate. However, if fluid is flowing inside the tubular member 12, the fluid will flow with respect to the geometry of the tubular member 12 as described by the geometric term "flow direction" of the structure of the tubular member 12.

[0017] Referring to FIG. 10, there is shown an enlarged side cross-sectional view of a second portion of the enhanced container system 10 in an upright position and with the liquid in an empty state. The tubular member 12 is indicated by exemplary flow direction indicators D1, D2, D3, D4, and D5. Repeating what has been said above, these flow direction indicators show how the tubular member 12 is constructed due to having various flow directions, and the "flow direction" is a term used herein to describe the geometry of the structure of the tubular member 12 regardless of the actual fluid flow rate. However, if fluid is flowing inside the tubular member 12, the fluid would be flowing with respect to the geometry of the tubular member 12 as described by the geometric term "flow direction" of the structure of the tubular member 12. An improvement in this regard is that in some embodiments, there may be a more complex tubular geometry at a particular location where the term "flow direction" also needs to describe the sum or average "flow direction" at that particular location. Since the term "flow direction" involves a direction, it is natural that vector components can be associated with the "flow direction" term. This term "flow direction" can also be used, for example, in expressions such as "cross-sectional flow area taken perpendicular to a particular flow direction" to serve the purpose of specifying the geometric cross-sectional area at a particular location of the tubular member 12. These cross-sectional areas for some embodiments and locations of the tubular member 12 may be based on a circular cross-section, but for other embodiments or locations of the tubular member 12, they may be based on a non-circular cross-section.

[0018] Referring to FIG. 11, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in an upright position and in a first liquid surface state having a surrounding liquid level B1, surrounding air B2, and liquid B3.

[0019] Referring to FIG. 12, there is shown an enlarged side cross-sectional view of a first portion of the enhanced container system 10 in an upright position and in a first liquid surface state.

[0020] Referring to FIG. 13, there is shown an enlarged side cross-sectional view of the third part of the enhanced container system 10 in the upright position and in the first liquid level state.

[0021] Referring to FIG. 14, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in the upright position and in the second liquid level state.

[0022] Referring to FIG. 15, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in the upright position and in the second liquid level state.

[0023] Referring to FIG. 16, there is shown an enlarged side cross-sectional view of the third part of the enhanced container system 10 in the first inclined position and in the third liquid level state.

[0024] Referring to FIG. 17, there is shown a side cross-sectional view of the enhanced container system 10 in the second inclined position and in the fourth liquid level state, showing the liquid level B4 of the enclosed liquid, the enclosed air B5, and the liquid B3 exiting the container assembly 14 as indicated by the dispensed liquid C1. At this point, a fluctuating flow of the ambient air B2 within the tubular member 12 occurs, and as a result, the acoustic generation of the acoustic emitter 16 will fluctuate.

[0025] Referring to FIG. 18, there is shown an enlarged side cross-sectional view of a part of the enhanced container system 10 in the second inclined position and in the fourth liquid level state having bubbles B6.

[0026] Referring to FIG. 19, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in the third inclined position and in the fifth liquid level state.

[0027] Referring to FIG. 20, there is shown an enlarged side cross-sectional view of a portion of the enhanced container system 10 in a third inclined position, with the peripheral liquid surface B7 around the liquid surface B8 of the contained liquid, and in a fifth liquid surface state. Unlike the conventional container system 100, as shown in FIGS. 4 and 5, the enhanced container system 10 includes an expansion portion 12c that can hold a sufficient amount of liquid B9 to continuously vary the flow of the ambient air B2 within the tubular member 12 and thus continuously vary the acoustic emission of the acoustic emitter 16.

[0028] Referring to FIG. 21, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in a fourth inclined position and in a sixth liquid surface state.

[0029] Referring to FIG. 22, there is shown an enlarged side cross-sectional view of a portion of the enhanced container system 10 in a fourth inclined position and in a sixth liquid surface state.

[0030] Referring to FIG. 23, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in a second inclined position and in a fourth liquid surface state. In an embodiment, it is shown that the enhanced container system 10 includes a tubular member 12' having a longitudinal portion 12a', a direction-changing portion 12b', and an expansion portion 12c' shown as being extremely large.

[0031] Referring to FIG. 24, there is shown a side cross-sectional view of the enhanced container system 10 in a fourth inclined position and in a sixth liquid surface state, which shows the result of having an extremely large expansion portion 12c' at this fourth inclined position of the enhanced container system 10, where a portion of the liquid B9 undesirably enters the acoustic emitter 16. In some embodiments, the undesired entry of a portion of the liquid B9 into the acoustic emitter 16 can be reduced or eliminated by sizing the volumes of the various portions of the tubular member 12 relative to each other. For example, in some embodiments, the total volume of the expansion portion 12c is sized relative to the volume of the direction-changing portion 12b such that the volume of the expansion portion 12c is larger than the volume of the direction-changing portion 12b.

[0032] Referring to FIG. 25, there is shown an enlarged side cross-sectional view of the enhanced container system 10 in a third inclined position and a fifth liquid level state. In an embodiment, the enhanced container system 10 is shown to include a tubular member 12” having a longitudinal portion 12a”, a direction-changing portion 12b”, and an enlarged portion 12c” shown as being small.

[0033] Referring to FIG. 26, there is shown an enlarged side cross-sectional view of a portion of the enhanced container system 10 in a third inclined position and a fifth liquid level state. As a result of having the small enlarged portion 12c”, this is shown at this third inclined position of the enhanced container system 10, and the ambient air B2 can move through the air flow path B10 as a stable, non-fluctuating flow, thereby causing the acoustic emitter 16 to emit a stable, rather than fluctuating, acoustic that is not desirable. In some embodiments, this undesirable state where the ambient air B2 can move through the air flow path B10 as a stable, non-fluctuating flow can be reduced or eliminated by sizing the various portions of the tubular member 12 relative to each other. For example, in some embodiments, the combined volume of the longitudinal portion 12A and the direction-changing portion 12b is sized relative to the other, such that the combined volume of the longitudinal portion 12A and the direction-changing portion 12b is larger than the volume of the enlarged portion 12c.

For example, by way of aid in understanding, the following claims may include the use of introductory phrases "at least one" and "one or more" that introduce the claim recitation. However, the use of such phrases should not be construed as implying that the introduction of a claim recitation by the indefinite article "a" or "an" limits any particular recitation that includes such introduced claim recitation to a claim that includes only one such recitation, and the same is true for the use of the definite article used to introduce the claim recitation.In addition, when a specific number of descriptions of the introduced claims are explicitly described, one of ordinary skill in the art will understand that such a description is to be interpreted as meaning at least one described number (e.g., the minimum description of "two descriptions" without other qualifying phrases generally means at least two descriptions, or two or more descriptions). Further, when a convention similar to "at least one of A, B, and C, etc." is applied, generally, such a construction is intended in the sense that one of ordinary skill in the art will understand the convention (e.g., "a system having at least one of A, B, and C" will include, but not be limited to, a system having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). In those examples where a convention similar to "at least one of A, B, or C, etc." is used, generally, such a construction is intended in the sense that one of ordinary skill in the art will understand the convention (e.g., "a system having at least one of A, B, or C" will include, but not be limited to, a system having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.).

For example, the phrase "A or B" is generally understood to include the possibility of "A" or "B" or "A and B".

[0035] Regarding the appended claims, those skilled in the art will understand that the operations recited herein may generally be performed in any order. Also, although various operation flows are presented in an order (or orders), it should be understood that various operations may be performed in an order different from the illustrated order, or may be performed simultaneously. Examples of such alternative orderings may include, unless the context dictates otherwise, repetition, interleaving, interruption, rearrangement, incremental, preparatory, supplementary, simultaneous, reverse, or other variant orderings. Further, terms such as "in response to", "relating to", or other past tense adjectives generally do not intend to exclude such variations unless the context dictates otherwise.
