Description

  The present invention relates to a container configured to dispense fluid, and more particularly to a container used to dispense oil. Most particularly, the present invention relates to a container that can be used to dispense oil to an engine of a vehicle, particularly an automobile.

  Oil, such as that used in automobiles, is often supplied in large and bulky containers. In the automotive industry, it is generally preferred to supply oil to a 4 liter to 5 liter container corresponding to the typical oil pan capacity of an automobile. When oil is added to an automobile engine, the liquid is often dispensed from the container through an opening in the engine. However, the size of such a container, combined with the oil stored in it, can lead to inconvenience that leads to difficulties during the filling operation, as well as frequent spills. Will be. This problem is further exacerbated by the fact that in recent automobiles the engine is housed in the lower part of the car body, resulting in more difficult access and an increased chance of spillage during the infusion operation.

  Furthermore, conventional oil containers have further disadvantages. As the liquid is discharged from the container, external air enters the container through the liquid dispenser so as to equalize the pressure differential caused by the discharge of the liquid. However, when a large amount of liquid is poured, the air entering the container is insufficient or completely blocked. As a result, a pressure difference is generated between the inside and the outside of the container. Due to this pressure difference, when the liquid is poured, the liquid flows intermittently in a motion that repeats alternately, or a “gobbling” motion. When handling a conventional 5 liter oil container so that this phenomenon does not occur, it is particularly difficult to maintain a properly tilted position, especially when the container is almost full. If the angle of tilting the container is too gentle, the flow rate of fluid exiting the dispenser will be too small and the oil will only flow down the outer wall of the container. If the tilt angle is too sharp, the flow rate is too high and the liquid exiting the container can be “too much” for the engine opening to which the oil is to be poured. Given that modern engines have complex external shapes and many collateral aspects, spilling oil into the engine chamber can be particularly difficult to clean and has various harmful effects. May lead to some effects. Furthermore, when the engine is heated, the burning of the oil can produce an unpleasant odor and smoke.

  Considering the fact that oil is an increasingly rare and valuable commodity and the above-mentioned problems associated with conventional oil containers, many efforts have been made to improve oil storage and oil dispensing means. . It is also a simple solution to use the funnel in the engine opening before the filling operation. However, using a funnel can cause contamination from any material or liquid that adheres to the surface of the funnel. Therefore, a cleaning operation is required before the start of the injection operation.

  Alternatively, improving the liquid dispensing means or nozzle to incorporate an air inlet that is separable from the liquid discharge portion has also been proposed as another solution (eg, US Pat. Reference 2). While such containers can overcome the “boggling” phenomenon to some extent, this type of container does not have additional means to control the flow rate and accuracy of dispensing liquid from the container. ing.

  Accordingly, there is a need for an improved container that is configured to dispense fluid so that these problems can be overcome. In particular, a fluid that can overcome the “gobo” problem during the infusion operation and provide improved means configured to control the flow rate of the fluid as it exits the container There is a need for a container for a dispenser.

The neck (11) allows the flow control assembly (20) to be connected to the body (90) and the reservoir (10) by engaging with the threaded portion (29a) of the body.

  Referring to FIG. 3, the flow control assembly (20) comprises a housing (22), an internal member (30), control means (50), a nozzle (14), an air inlet (38), and a fluid outlet (40). ing. The nozzle (14) can be integrally formed as part of the housing (22) or can be connected to the housing (22). The housing (22) may comprise a generally cylindrical tube having a first end proximate to the nozzle (14) and a second end proximate to the control means (50). The housing (22) can be composed of any moldable material having oil resistance, such as plastic or metal. In one embodiment, the housing (22) is constructed from a plastic material such as high density polyethylene. Typically, the length of the housing (22) is from 100 mm to 120 mm and the diameter is from 30 mm to 40 mm. The housing (22) further includes a first opening (24) and a second opening (26) formed in the housing wall (22a). The first and second openings (24, 26) are preferably formed in the part of the wall (22a) closest to the reservoir (10). The first opening (24) can be formed in a substantially circular or elliptical shape. Alternatively, the first opening (24) can be diamond-shaped. The second opening (26) can also be formed in a generally circular or elliptical shape. Alternatively, the second opening (26) can be diamond-shaped. However, as will be appreciated by those skilled in the art, the first opening (24) and the second opening (26) may adopt various shapes, and the present invention is not limited in this regard. . The cross-sectional area of the first opening (24) is such that fluid can effectively move from the reservoir (10) through the first opening (24) when the container (100) is properly tilted during use. And is large enough to exit the nozzle (24). The cross-sectional area of the first opening (24) is preferably larger than the cross-sectional area of the second opening (26). Typically, the cross-sectional area of the first opening (24) is at least twice the cross-sectional area of the second opening (26). In one embodiment, the cross-sectional area of the first opening (24) is three times the cross-sectional area of the second opening (26). In another embodiment, the cross-sectional area of the first opening (24) is four times the cross-sectional area of the second opening (26). The flow control assembly (20) further comprises a fluid flow portion (27) and an air flow portion (28). A fluid flow portion (27) and an air flow portion (28) extend from the housing (22) and correspond to the first opening (24) and the second opening (26), respectively. The fluid flow part and the air flow part (27, 28) are preferably made of the same material as the housing (22). The fluid flow portion (27) is defined by the wall (27a), and the air flow portion (28) is formed by the wall (28a). The fluid flow part (27) and the air flow part (28) are spatially separated by the wall part (22b) of the housing (22). Typically, the fluid flow and air flow (27, 28) of the flow control assembly (20) is the same as the fluid flow and air flow (12, 13) of the neck (11) of the container (100). It is designed to be aligned.

  In embodiments where the housing (22) comprises a generally cylindrical tube, the cross-sectional area of the housing (22) can be constant throughout the length of the tube. In other embodiments, the housing (22) can have a larger cross-sectional area at one end. In one embodiment, the second end of the housing (22) proximate to the flow control means (50) is larger than the first end of the housing (22) proximate to the fluid dispensing means (14). It has a cross-sectional area. In one embodiment, the housing (22) can be inclined outwardly in the direction of the control means (50).

  3 and 4, the internal member (30) is configured to be mounted within the housing (22). Accordingly, the outer shape of the inner member (30) is formed so as to substantially match the inner shape of the housing (22). Therefore, when the housing (22) is substantially cylindrical, the outer shape of the inner member (30) is also substantially cylindrical. Thus, in one embodiment, the inner member (30) can comprise a generally cylindrical member having a tubular portion. It is preferred that the inner member (30) can have a slightly smaller diameter than the housing (22) so that the inner member (30) can be mounted within the housing (22) by a tight friction fit. . However, such fitting is of a nature that allows the internal member (30) to move within the housing (22). In a preferred embodiment, the inner member (30) can move rotatably within the housing (22). Typically, the length of the internal member (30) is from 100 mm to 120 mm, and the diameter is from 30 mm to 40 mm. In embodiments configured to mount the internal member (30) within the housing (22), it is preferred that the length and diameter of the internal member (30) be smaller than the length and diameter of the housing (22).

  The inner member (30) can be constructed from any moldable material that is oil resistant, such as plastic or metal. In one embodiment, the inner member (30) is constructed from a plastic material such as high density polyethylene. The internal member (30) includes a wall (30a), an air inflow portion (38a), a fluid discharge portion (40a), a fixing member (39), a first opening (34), and a second opening (36). ing. It is preferable that the internal member (30) can be formed so that the fluid discharge portion (40a) and the air inflow portion (38a) are integrated in the internal member (30). The fluid discharge part (40a) extends from the fluid outlet (40), and the air inlet part (38a) extends from the air inlet (38). Thus, the fluid discharge part (40a) and the air inflow part (38a) extend within the main body of the internal member (30). As shown in FIGS. 3 and 4, the air inflow portion (38a) includes a channel defined between the fixing member (39) and the wall (30a). The channel extends in the internal member (30) and is connected to a chamber (35) having an internal space larger than the volume of the air inlet (38a).

  The first opening (34) of the inner member (30) can be formed in a substantially circular or elliptical shape. Alternatively, the first opening (34) can be diamond-shaped. Although the first opening (34) can be formed in a variety of different shapes, in an even more preferred embodiment, the first opening (34) in the inner member is the first opening (in the housing (22) ( It is formed so as to complement the shape of 24). The second opening (36) of the inner member (30) can also be formed in a generally circular or elliptical shape. Alternatively, the second opening (36) can be diamond-shaped. Similar to the first opening, the second opening (36) in the internal member (30) is preferably formed to complement the shape of the second opening (26) in the housing (22). Typically, the diameter of the first and second openings (34, 36) of the inner member (30) is the same as the first and second openings (24, 26) of the housing (22), respectively. ing.

  The internal member (30) has a first end proximate to the nozzle (14) and a second end proximate to the control means (50). The fixing member (39) or the partition wall partitions the fluid discharge part (40a) and the air inflow part (38a). The fixing member (39) extends upward from a part of the wall (30b) of the inner member (30) located between the first opening (34) and the second opening (36), so that the nozzle (14 ) Is terminated at the first end close to. The fixing member (39) can be bent in the region directly above the first opening (34). The bending of the fixing member (39) in this region advantageously allows the fluid to flow smoothly after leaving the first opening (34) when the container (100) is tilted at a sharp angle. It becomes easy to flow toward the exit (40). As shown in FIG. 5, the cross-sectional area of the fluid outlet (40) is preferably larger than the cross-sectional area of the air inlet (38). Typically, the cross-sectional area of the fluid outlet (40) is at least twice that of the air inlet (38). In one embodiment, the cross-sectional area of the fluid outlet (40) is three times the cross-sectional area of the air inlet (38). In another embodiment, the cross-sectional area of the fluid outlet (40) is four times the cross-sectional area of the air inlet (38). Furthermore, the internal space included in the fluid discharge part (40a) is preferably larger than the internal space of the air inflow part (38a). Therefore, when the internal member (30) is formed so as to enlarge the internal space of the fluid discharge part (40a), the nozzle region (14) of the container is divided into a separate fluid discharge part (40a) and an air inflow part (38a). This will ensure that the effect on the volume of the fluid that can be drained is minimized.

  The control means (50) of the flow control assembly (20) is preferably located at the distal end of the nozzle (14). The control means can include an engaging means such as an arm, a lever, or a rotating means. In a preferred case, the control means (50) preferably comprises a tap (51). The tap part (51) can be provided with ridges (51a) arranged at equal distances to assist rotation while grasping. The control means (50) can be formed integrally with the internal member (30) or can be a separate component in communication with the internal member (30). In arrangements where the control means (50) is in communication with the internal member (30), the control means (50) can be connected to or attached to the internal member (30) by any suitable means. In some embodiments, the protrusions or ribs formed inside the control means (50) engage the corresponding tears or grooves on the outside of the internal member (30) to rotate the internal member (30). Can do. In other embodiments, the inner member (30) comprises protrusions or fins that can engage a corresponding groove formed in the control means (50) to rotate the inner member (30). In a further embodiment, the control means (50) can slidably engage the internal member (30). Therefore, the control means (50) can be moved by sliding between the front position and the rear position. When the control means (50) is in the forward position and is engaged with the internal member (30), the control means (50) can move rotatably, and the control means (50) and the internal member (30) will result in both rotational movements. Alternatively, the control means (50) can be configured to fit a portion within the internal member (30). In this embodiment, the control means (50) comprises a cylindrical portion (52) having a diameter smaller than the diameter of the inner member (30), the cylindrical portion (52) being a tube of the inner member (30). Can be fitted inside. Alternatively or in addition, the internal member (30) can be configured such that the control means (50) can be inserted. For example, the inner member (30) can be tilted outward, or the straight section of the tube of the inner member (30) can have a larger cross-sectional area to receive the control means (50). In all embodiments, the control means (50) can move relative to the housing (22), and in a preferred embodiment the control means can move rotatably relative to the housing (22). .

  The control means (50) can be moved by engagement of a lever, arm or rotating means. In a preferred case where the control means (50) includes a tap portion (51), the control means can be moved by rotating the tap portion. In an embodiment where the control means (50) communicates with the internal member (30), moving the control means (50) results in the internal member (30) moving. A portion of the control means (50) can be configured to be mounted in the housing (22) using the same means as the inner member (30) is mounted in the housing (22). For example, the housing (22) can be tilted outward or the straight section of the tube of the housing (22) can have a larger cross-sectional area to receive the control means (50). The control means (50) can move in a range of different positions including at least one closed position and at least one open position. Appropriate markings or indicia on the control means (50), flow control assembly (20), and / or container (100) are appropriate to indicate the respective positions of the open and closed positions (or any intermediate position). It can be attached to any part. When the control means (50) includes the rotation means or the tap portion (51), the control means (50) can rotate within a range of 360 °. Thus, the flow control assembly (20) can employ a number of different “open” positions that can be used to control the flow rate of the fluid as it is dispensed from the container (100). The control means (50) may further comprise an additional mechanism configured to limit the maximum flow rate. For example, the control means (50) can comprise a protrusion or abutment surface formed therein, and once the protrusion or abutment surface has moved beyond a certain position, the corresponding protrusion or abutment. When hitting the surface, the control means (50) does not move further. Therefore, the control means (50) is provided with projections that correspond to the corresponding projections formed on the inner wall of the internal member (30) or the housing (22) to prevent further rotation. In another embodiment, the protrusion or abutment surface can be dimensioned such that it merely restricts further movement or rotation of the control means (50) and does not prevent it completely. Therefore, when the user further applies torque or force to the tap portion or the rotating means, the resistance can be overcome and further movement can be performed. In addition, the container (100) can include one or more mechanisms configured to prevent the control means (50) from moving when fluid is not dispensed from the container (100). For example, the control means (50) can move between a front position and a rear position. In such an embodiment, the first and second flow paths can be opened only by further moving (eg, rotating) the control means when the control means (50) is in the forward position. Therefore, when the control means is at the rear position, the rotation of the control means is hindered, and the first and second flow paths cannot be opened. The control means can move slidably between a front position and a rear position.

When the control means (50A) is moved to the open position, the inner member (32A) is moved at the same time, and a part of the first and second openings (34A, 36A) of the inner member (32A) are respectively housed. It overlaps with a part of the first and second openings (24A, 26A) of (22A). In a preferred embodiment in which air can enter the air inlet (38A) only when the control means (50A) is in the open position, external air passes through the air inlet (38A) and passes through the tubular inner member. It flows in the internal space of (32A). In one preferred embodiment, as shown in FIG. 7, the air is in a gap between the shoulder (23A) of the housing (22A) and the wall of the inner member (32A) or the cylindrical portion (52A) of the control means. It enters through the air inlet (38A) via the formed recess (33A). The air then passes through the through hole (46A) formed by the second opening of the inner member (32A) overlapping the second opening of the housing (22A), through the second neck (12B), It then flows along the conduit or passage defined by the duct (17A). Once air enters the duct (17A), it can communicate with the reservoir (10A) via the lower and upper couplings (16Aa and 16Ab). In a preferred embodiment, air can communicate with the reservoir (10A) via only the lower coupling portion (16Aa). Thus, the air flow path from the external atmosphere to the storage section (10A) is indicated by the arrow A in FIG. When the infusion operation begins, fluid from the reservoir (10A) flows along the first neck (12A) and the first opening (34A) of the inner member (32A) is the first of the housing (22A). It flows through the through hole (44A) formed by overlapping with the opening (24A), flows along the fluid discharge part (40Aa), and flows out from the nozzle dispensing means (14A). The fluid flow path from the reservoir (10A) through the first neck (12A) is indicated by arrow B. When fluid is exhausted from the container (100A) along path B, external air enters the container through the air inlet (38A) and flows along path A to equalize the pressure differential caused by the fluid discharge. Turn into.

  In all embodiments, the container (100, 100A, 100B) of the present invention has two independent paths: one path for draining fluid from the container and a second for flowing air exclusively into the container. Provide a route. As fluid is exhausted from the container (100, 100A, 100B) along the first path, external air enters the container through the air inlet (38, 38A) and flows along the second path. , Equalize the pressure difference caused by fluid discharge. This ensures that the fluid can be poured smoothly, avoiding alternating or sporadic “gobobbling” movements as experienced with prior art containers. Furthermore, the inner member (30, 32A, 32B) and the housing (22, 22A, 22B) are arranged so as to be inclined downward toward the control means (50, 50A, 50B), and when the injection operation is completed, The fluid naturally flows back along the fluid discharge part (40a, 40Aa, 40Ba), flows through the first opening (24, 24A, 24B), and reenters the storage part (10, 10A, 10B). Can do. This ensures that fluid does not accumulate in the nozzle area (14, 14A, 14B) and therefore reduces the risk of leakage. Typically, the tilt angle can be 5 degrees to 15 degrees.

  In the container (100, 100A, 100B) of the present invention, the first and second openings of the housing (22, 22A, 22B) are respectively the first and second openings of the internal member (30, 32A, 30B). The ability to adjust the overlap range also provides an effective means of controlling the flow of fluid discharged from the nozzles (14, 14A, 14B). The tap portions (51, 51A, 51B) of the control means (50, 50A, 50B) are connected to the first and second openings of the housing (22, 22A, 22B) and the first of the internal members (30, 32A, 30B). And when rotating so that the overlap with the second opening is small, the cross-sectional area of each through hole is also small. As a result, the flow rate of the fluid dispensed from the container (100, 100A, 100B) is the first and second openings of the housing (22, 22A, 22B) and the first of the internal members (30, 32A, 30B). And compared with the case where the degree of overlap with the second opening is large, it is relatively small. Therefore, the maximum flow rate of the fluid is such that the first and second openings of the housing (22, 22A, 22B) and the first and second openings of the inner member (30, 32A, 30B) are aligned with each other. (I.e. completely overlapping) can be achieved. Thus, the flow control assembly (20, 20A, 20B) of the present invention can preset many different flow rates by adjusting the position of the control means (50, 50A, 50B) before starting the injection operation. . Furthermore, the control means (50, 50A, 50B) can be adjusted in small increments for the convenience of the user to increase or decrease the flow rate during the infusion operation. Thus, the container of the present invention allows active control of fluid flow. Alternatively, the first opening (24, 24A, 24B) of the housing partially overlaps the first opening (34, 34A, 34B) of the inner member, but the second opening (26, 26A, 26B) of the housing. ) And the second opening (36, 36A, 36B) of the internal member, the user arbitrarily controls the tap portion (51, 51A, 51B) of the control means (50, 50A, 50B). Can be rotated. In this arrangement, the container will operate as a conventional fluid dispenser.

  By providing the auxiliary safety mechanism in the container (100, 100A, 100B), it is possible to reliably prevent the user from inadvertently adjusting the control means (50, 50A, 50B) so that the flow rate becomes too high. . This is because when the protrusion or abutment surface is incorporated in the control means (50, 50A, 50B) and the tap portion or the rotation means (51, 51A, 51B) exceeds the point where it is rotated, the internal member (30 , 32A, 30B) or the corresponding protrusion formed on the inner wall of the housing (22, 22A, 22B). At this time, the user overcomes the resistance and moves it further (for example, to move it to a position where the openings of the internal member (30, 32A, 30B) and the housing (22, 22A, 22B) completely overlap). Further, only by applying torque or force, the tap portion or the rotating means (51, 51A, 51B) can be continuously rotated.
