Detailed Description

Referring now to FIG. 1, shown is a perspective view of a container according to one embodiment of the present invention. As shown, the container 1 includes a dosing dispenser 10 and a container body 20 attached to the dosing dispenser 10. A metered dose dispenser 10 for delivering metered doses of product from the container body 20 may be attached to or seated on the container body 20. The metered dose dispenser 10 may be used to pour a desired amount of liquid or fluid from the container body 20 for various purposes. For example, a metered dose dispenser according to one embodiment of the present invention may be used to pour a desired dose of laundry detergent, soap, detergent, beverage, sauce, lotion or other product as desired. These products are collectively referred to herein as "fluids". While the metered dose dispenser 10 and container body 20 may have the aesthetic appearance shown in fig. 1, it should be understood that the features of the dispenser 10 and container body 20 in various embodiments of the present invention may be combined with other aesthetic appearances and appearances, as well as other features.

Fig. 2 and 3 show perspective views of the metered dose dispenser 10 in a closed state and in an open state, respectively, according to one embodiment of the invention. As shown, the metered dose dispenser 10 includes a base 100 and a lid 300 attached to the base 100. The lid 300 may be fitted over the base 100 and secured to the base 100. The cover 300 may include a flip portion 302 having a living hinge 304, the living hinge 304 connecting the flip portion 302 to the remainder of the cover 300 such that the flip portion 302 may be opened or closed relative to the base outlet 102 (see fig. 4) to open or close a pouring fluid output flow path a and a gas vent flow path C (see fig. 8) described below. The flip portion 302 may include an inner sealing ring 306 on a side thereof facing the base 100, the inner sealing ring 306 configured to mate with the base outlet 102 or seal the outlet 102 to help prevent fluid from leaking out of the dosing dispenser 10 when the flip portion 302 is closed and the inner sealing ring 306 is seated in the base outlet 102 or, in some embodiments, around the base outlet 102. For example, when the flip portion 302 is closed, the inner sealing ring 306 may be used to hermetically seal a portion of the base 100, thereby closing the pour fluid output flow path a and the gas vent flow path C. With the flip portion 302 open, both the pouring fluid output flow path a and the gas vent flow path C are exposed to the atmosphere, as shown in fig. 8.

The cover 300 may also include a window 308, and the window 308 may be formed of a clear, transparent, or opaque material, allowing a user to see the metered fluid flowing through the window 308. As shown in fig. 2, the window 308 is configured as a transparent arcuate projection defining an arcuate channel on the interior of the projection for passage of the metering fluid. Further, two generally oval-shaped protrusions may be provided on either side of the projection, respectively, which are fitted to corresponding portions of the base 100 for securing the lid 300 to the base 100, and may also serve as indicia showing how much fluid has been dispensed from the dispenser 10. In some embodiments, the window 308 itself may be marked with a scale or other indicator to allow a user to determine the amount of fluid that has been dispensed.

Turning now to fig. 4, a cross-sectional view of a metered dose dispenser according to one embodiment of the present invention is shown. As shown, the metered dose dispenser 10 may include three portions: a base 100; an insert 200 attached to the base 100; and a lid 300 attached to the base 100. All three parts may be molded from, for example, polypropylene. The base 100 may include features configured to retain the insert 200 and the lid 300 therein. For example, as shown, the base 100 may include an insertion groove 110 that opens upward or downward. The insert 200 has a partition wall 204 projecting upward from a bottom plate thereof, and an insertion portion 206 which is a part of the partition wall 204 is inserted into the insertion groove 110 opened downward of the base 100. In some embodiments, the insert 200 may also be snap-fit or otherwise fit into the base 100 and held in place for use of the metered dose dispenser 10. As shown in the drawing, the cover 300 has fitting projections 312 extending downward at both left and right end portions of the window 308, and the fitting projections 312 are fitted into the fitting grooves 110 opened upward of the base 100. In some embodiments, the lid 300 may also be welded or adhered to the base 100 to secure the lid 300 to the base 100.

The base 100 may include a peripheral portion extending downwardly along its outer periphery, with one or more threads 112 provided on the inner surface of the peripheral portion, thereby allowing the base 100 to be screwed onto corresponding threads of the mouth of the container body 20. In some embodiments, other connecting elements molded into the base 100, such as snap-fit elements or bayonet features, may also be used for connecting the base 100 to a container body 20 having similar elements. The base 100 may also include an engagement flange 114 extending downwardly and spaced from the peripheral edge portion. The outer periphery of the insert 200 engages the inner surface of the engagement flange 114 and the mouth of the container body 20 is received in the gap defined by the outer surface of the engagement flange 114 and the peripheral edge portion. In some embodiments, the metered dose dispenser 10 may further include a gasket 400 seated within the base 100 and positioned between the walls of the base 100 and the upper portion of the container body 20 for sealing the container body 20 relative to the base 100. The gasket 400 is made of, for example, foamed polyethylene, and is commercially available.

As shown, the base 100 includes a pouring fluid channel 104 and a metering fluid channel 106 that are in fluid communication with a first opening 208 and a second opening 210, respectively, provided in the insert 200, as described below. When pouring fluid from the container body 20 attached to the metered dose dispenser 10, the fluid contained within the container body 20 may flow through the pouring fluid channel 104 and the base outlet 102 out of the metered dose dispenser 10. At the same time, a portion of the fluid will flow as a metering fluid through the metering fluid passage 106 and the arcuate passage 310 provided in the cap 300. In some embodiments, the metering fluid flow path provided in the cap 300 is entirely comprised of arcuate channels. The metering fluid exiting metering fluid passage 106 immediately impinges upon the arcuate wall of arcuate passage 310 and is directed by the arcuate wall to flow along arcuate passage 310.

The base 100 may also include a guide 108 for directing all of the metering fluid exiting the arcuate channel 310 through the third opening 212 provided in the insert 200, as described below. In some embodiments, the guide 108 may act as part of a wall of the arcuate channel 310, defining a portion of the arcuate channel 310 with the window 308 of the cover 300. Optionally, arcuate channel 310 may also be formed only in window 308 of cap 300, having an inlet at an upstream end in communication with metered fluid passage 106, and an outlet at a downstream end facing third opening 212. In this case, the channel wall surrounding the outlet of the arc-shaped channel 310 is configured as a guide.

In fig. 5 to 7 an insert in a dosing dispenser according to an embodiment of the invention is shown, wherein fig. 5 shows a bottom view of a dosing dispenser provided with the insert, fig. 6 shows a perspective view of the insert seen from the bottom, and fig. 7 shows a perspective view of the insert seen from the top.

As shown in fig. 4 and 5, the insert 200 is insert-mounted into the base 100 from below the base 100. Specifically, the embedding portion 206 of the partition wall 204 of the insert 200 is embedded in the embedding groove 110 of the base 100, which opens downward, and the outer periphery of the insert 200 is engaged with the inner surface of the engaging flange 114 of the base 100. In some embodiments, the insert 200 may have a flange projecting downward from the generally planar floor 202 along its outer periphery. The outer surface of the flange engages with the inner surface of the engagement flange 114 of the base 100 to increase the contact area therebetween and improve the fixing effect. Further, the flange may have an inner diameter that is slightly larger than the inner diameter of the engagement flange 114, thereby forming an interference fit between the insert 200 and the base 100.

As shown in fig. 6 and 7, the insert 200 includes a partition wall 204 protruding upward from a bottom plate 202 thereof, and a first opening 208, a second opening 210, and a third opening 212 configured to pass through the bottom plate 202. The partition wall 204 surrounds the second opening 210 and separates the second opening 210 from the first opening 208 and the third opening 212. The second opening 210 is disposed within the interior space defined by the partition wall 204, while the first opening 208 and the third opening 212 are disposed outside of the partition wall 204. As shown, the partition wall 204 includes, from left to right, a first section, a second section, a third section, and a fourth section protruding upward from the bottom plate 202. The upper edge of the first section is parallel to the surface of the base plate 202. The upper edge of the second section is parallel to the surface of the base plate 202 and has a height greater than the height of the first section. The upper edge of the third section has a height that gradually decreases from left to right. The upper edge of the fourth section is parallel to the surface of the bottom plate 202 and has a lower height than the height at the right end of the third section. The second and third sections of the insert 200 constitute the aforementioned embedding portion 206, and the embedding portion 206 is inserted into the embedding groove 110 of the base 100 to fix the insert 200 to the base 100. A gap between the upper edge of the fourth section and the upper edge of the third section forms a part of a gas ventilation flow path C (see fig. 8) described later.

In some embodiments, the insert 200 includes a divider extending outwardly from the divider wall 204 and upwardly from the base plate 202 to further separate the third opening 212 from the first opening 208 to isolate the dumped fluid output flow path a from the metered fluid return flow path B and the gas vent flow path C (see fig. 8), as described below. In some embodiments, the insert 200 may also include one or more fourth openings 214. The fourth opening 214 is surrounded by the partition wall 204 and allows air or gas to flow into the container body 20 to ventilate the interior of the container body 20 during and after operation of the metered dose dispenser 10. In the embodiment shown in fig. 7, two fourth openings 214 are provided on the area of the base plate 202 surrounded by the partition wall 204 in symmetrical positions with respect to a straight line connecting the center of the base plate 202 and the center of the second opening 210. Optionally, only one fourth opening 214 may also be provided in this line.

As shown, one second opening 210 is disposed at a substantially central position of the bottom plate 202, and two first openings 208 are symmetrically disposed at both sides of the second opening 210. A straight line connecting the centers of the two first openings 208 and a straight line connecting the centers of the bottom plate 202 and the second opening 210 are perpendicular to each other. In some embodiments, only one or more than two first openings 208 may be provided, and two or more than two second openings 210 may also be provided. The first opening 208 is in fluid communication with the pouring fluid channel 104 of the base 100 and is configured to allow pouring fluid to flow from the interior of the container body 20, through the insert 200, and into the pouring fluid channel 104 of the base 100 when the metered dispenser 10 is in its dispensing position. The second opening 210 is aligned with the metered fluid passage 106 of the base 100 and is configured to allow the metered fluid to flow from the interior of the container body 20 into the metered fluid passage 106 of the base 100 during operation of the metered dose dispenser 10.

The diameter or area of each first opening 208 may be adjusted based on the fluid characteristics and the desired flow characteristics of the system. The size, diameter, or area of each second opening 210 may also vary or vary for the particular fluid to be dispensed. In this way, the metered dose dispenser 10 may be used for a variety of applications with fluids having different characteristics (such as viscosity) by changing only one portion (i.e., the insert 200). In some embodiments, the size, diameter, or area of the second opening 210 may be selected and molded or shaped to provide a constant flow of fluid into the metering fluid channel 106, thereby obtaining a constant fill of the window 308 during operation, thereby allowing a user to measure the amount of fluid dispensed from the metered dose dispenser 10. Further, the first opening 208 and the second opening 210 may be relatively positioned and sized such that, upon pouring fluid from the container body 20, the amount of fluid flowing through the pouring fluid channel 104 via the first opening 208 is in fixed proportion to the amount of fluid flowing through the metering fluid channel 106 via the second opening 210. Based on this fixed ratio, a scale or other indicator may be configured on the window 308 of the cap 300, thereby accurately indicating how much fluid has been dispensed from the dispenser 10 through the pour fluid channel 104. In some embodiments, such a scale or other indicator may be configured based on the insert 200 and the fluid poured from the dispenser 10. For example, based on the characteristics of the fluid to be dispensed and the size of the various openings of the insert 200, the window 308 portion of the lid will fill at a given rate or a fairly constant rate. This allows for the inclusion of indicia on the window 308 to indicate how much fluid has flowed from the dispenser in a given amount of time.

As shown in fig. 6 and 7, the first and

second openings

208, 210 include a blocking element 216 to restrict the flow rate of fluid flowing through these

openings

208, 210. The blocking element 216 has a cylindrical boss 218 projecting upward from the bottom plate 202 of the insert, and a stop 222 connected to the cylindrical boss 218 via one or more ribs 220. The post boss 218 may have a generally cylindrical shape and the stop 222 may correspondingly have a generally circular shape. A plurality of ribs 220 spaced apart from one another connect the inner periphery of the post boss 218 and the outer periphery of the stop 222 and may be made of, for example, an elastomeric material. When pouring the fluid from container body 20, the fluid contained within container body 20 first flows through first opening 208 and second opening 210. Due to the stop 222, the flow rate of the fluid flowing through the first opening 208 and the second opening 210 is slowed. Specifically, the pouring fluid first flows through the voids between the plurality of ribs 220 in the blocking element 216 of the first opening 208, while the metering fluid first flows through the voids between the plurality of ribs 220 in the blocking element 216 of the second opening 210. As fluid flows through the first and

second openings

208, 210 at a slower rate, the graduations or other indicators provided on the window 308 can more accurately indicate the amount of fluid that has flowed from the dispenser in a given amount of time.

In some embodiments, the ribs 220 are angled downward from the inner periphery of the cylindrical boss 218 such that the stop 222 is located below the upper edge of the cylindrical boss 218. In this case, if the rib 220 is made of an elastic material, the stopper 222 is displaced upward by the impact effect of the flowing fluid, so that the flow path area between the columnar boss 218 and the stopper 222 is reduced, thereby further restricting the flow rate of the flowing fluid. The faster the outflow speed of the fluid, the more the flow path area is reduced, so the speed of the fluid flowing out through the first opening 208 or the second opening 210 can be automatically adjusted. Optionally, the ribs 220 may also be angled upward from the inner periphery of the cylindrical boss 218 such that the stop 222 is above the upper edge of the cylindrical boss 218.

In some embodiments, a blocking element 216 may be disposed in either of the first opening 208 and the second opening 210. For example, the blocking element 216 may be disposed in both first openings 208 or one of the first openings 208, or only in the second opening 210. In some embodiments, the blocking element 216 is removably mounted to each

opening

208, 210 and can be replaced depending on the characteristics of the fluid to be dispensed. As shown, the columnar boss 218 of the stopper member 216 provided in the second opening 210 has a substantially cylindrical step portion recessed downward on the inner side. The step abuts against the lower portion of the metered fluid passage 106 of the base 100 (see fig. 4) such that the metered fluid flowing through the second opening 210 does not leak into the interior space defined by the dividing wall 204 when the fluid is poured from the container body 20.

Fig. 8 shows a cross-sectional view of a dosing dispenser according to an embodiment of the invention, schematically showing various fluid flow paths, namely a pouring fluid output flow path a, a metering fluid return flow path B and a gas vent flow path C. As shown, the pouring fluid output flow path a is comprised of the first opening 208 provided in the insert 200, the pouring fluid channel 104 of the base 100, and a portion of the base outlet 102. The metered fluid return flow path B is comprised of the second opening 210 provided in the insert 200, the metered fluid passage 106 of the base 100, the arcuate passage 310 provided in the window 308 of the cap 300, and the third opening 212 provided in the insert 200. Further, the gas ventilation flow path C is constituted by a part of the base outlet 102, an internal space defined by the partition wall 204 of the insert 200, and a third opening 212 provided to the insert 200. In the case where the fourth opening 214 is provided in the bottom plate 202 surrounded by the partition wall 204, the gas ventilation flow path C further includes a branch from the aforementioned internal space through the fourth opening 214.

According to an embodiment of the present invention, when the container 1 with the doser 10 attached thereto is tilted to pour fluid from the container body 20 through the doser 10, the fluid exits the pouring fluid channel 104 of the base 100 and enters the dosing fluid channel 106 through the insert 200. As the fluid flows into the metering fluid channel 106, it slowly moves through the window 308 portion of the cap 300, allowing the user to see the flow of fluid and measure the amount of fluid that has been poured from the dispenser 10. As fluid flows from the dispenser 10, the user may view the window 308 and stop pouring when it has reached a specified portion of the time that they wish to be dispensed from the dispenser. Upon the user rotating the container 1 to face upward, the fluid located in the window 308 portion of the lid 300 flows back into the container body 20 through the third opening 212 of the insert 200.

During and after operation of the dosing dispenser 10, air or other gas enters the interior space defined by the partition wall 204 of the insert 200 through a portion of the base outlet 202 and flows across the partition wall 204, particularly the fourth section of the partition wall 204, through the third opening 212 of the insert 200. As shown in fig. 8, the guide 108 of the base portion is spaced apart from the partition wall 204, and the gas flowing across the partition wall 204 flows toward the third opening 212 via the gap between the partition wall 204 and the guide 108. Such airflow helps to force the metered fluid flowing out of the arcuate channels 310 provided in the windows 308 away from the dividing wall 204, thereby preventing such metered fluid from entering the aforementioned interior space or the dump fluid channel 104 of the base 100. As a result, a more accurate indication can be obtained regarding the amount of fluid that has flowed from the dispenser. With the separator disposed between the third opening 212 and the first opening 208, the metered fluid exiting the arcuate channel 310 toward the third opening 212 does not interfere with the poured fluid exiting the first opening 208, thereby enabling a more accurate indication of the amount of fluid that has exited the dispenser.

According to various embodiments of the present invention, the dosing dispenser may be customized for a particular fluid such that the dispenser may be configured with or assembled with an insert. The insert has a metering inlet (i.e., second opening 210) configured with a blocking element to restrict the flow of fluid into the window of the dosing dispenser so that a user can accurately judge or measure the amount of fluid dispensed from the dispenser. In various embodiments, the one or more metering inlets and the one or more pouring inlets (i.e., the first opening 208) may be configured such that the amount of fluid flowing through the pouring inlet corresponds to the amount of fluid flowing through the metering inlet such that a user may visually see the amount in a window that may include indicia to show how much fluid has been dispensed from the dispenser. For example, the diameter of the pour inlet may be proportional to the diameter of the metering inlet such that for a particular fluid characteristic, the ratio may be defined based on the fluid flow through the metering inlet and the diameter set to monitor the fluid flow through the dispenser.

While certain specific embodiments of the invention have been described in this way, it is to be understood that the invention defined by the appended claims is not to be limited by particular details set forth in the above description, as many apparent variations thereof are contemplated. Rather, the invention is limited only by the accompanying claims, which include within their scope all equivalent devices or methods that operate according to the principles of the invention as described.
