DETAILED DESCRIPTION OF THE INVENTION
The present invention is further described in the detailed description which follows, in reference to exemplary embodiments.
Non-Limiting Examples
With reference to FIGS. 1-6, there is shown a granulated product container package 1000 includes a generally cylindrical container body 200 that can have a volume of between, e.g., 1 and 32 ounces and a doser 100. The container 200, in embodiments, has a closed bottom, one or more sides and an open upper end that may be located in a narrower container neck region. In one exemplary embodiment, the container 200 is a one-piece glass or synthetic resin member that is food-grade material. The container package 1000 can containing a substance, e.g. particulate substance S. Although designed for particulate substances, the package 1000 can also be used to dispense liquids. The doser 100 comprises a dosing body or member 10 configured to be located at least partially inside a dispensing end or neck of the container 200. The dosing body or member 10 comprises at least a bottom wall 12 and a retaining wall 13 and a retaining space 16 of predetermined volume configured to retain a dispensable amount of said substance. When the doser 100 is arranged on a container 200 and the container dispenses the dispensable amount of the substance, the dosing member 10 substantially prevents the substance contained in the container from passing into the retaining space 16. A separating wall 15 extends down from an upper wall 18 and separates a dispensing volume from a receiving opening 17. An upper wall 18 includes projections 23 by which a user or consumer can rotate the doser 100 relative to the container 200. In addition, the wall 18 has sifting openings 21 that all the contents of the doser 100 to be dispensed and a main opening 22 that allows the substance to be dispensed by pouring out (bypassing the doser 100). A cover 30 (shown schematically) can be moved to a position cover the doser 100 and is attached to a living hinge LH. Although not shown in FIGS. 1-6, the doser 100 can be configured so that the upper wall 18 instead has the form of a rotating disk 20 (see position shown in FIG. 3) whose rotation would be facilitated by the projections 23 and allow the disk 20 to rotate relative to the member 10. As will be illustrated in other embodiments described herein, this can allow the positioning of a pouring opening or sifting openings over a dispensing opening of the member 10. In one exemplary embodiment of FIGS. 1-6, the member 10 is a one-piece synthetic resin member that is of food-grade material.
With reference to FIGS. 7-10, there is shown another embodiment of a doser body 10′. The doser member 10′ can be installed on a container such as container body 200 shown in FIG. 1. The doser member 10′ comprises at least a semi-cylindrical vertical side wall 11′, an angled bottom wall 12′, and a generally vertical retaining wall 13′. The bottom wall 12′ is angled such that a dispensable substance disposed in an internal space 16′ will flow down or settle toward a direction of the wall 11′. As should be apparent, the wall 11′ extends from the bottom wall 12′ to an upper wall 18′. The upper wall 18′ is shaped and sized to slid into an open end of a container, and, in this example, is generally circular. In addition, the wall 18″ is sized to be larger than the container opening so that an outer circumferential portion thereof forms a flange that sits atop of the container opening rim (as is illustrated in with respect to other embodiments discussed later on). The shape of the vertical wall 11′ also functions to properly located and center the member 10′ inside the container opening. The member 10′ also utilizes a vertical separating wall 15′ which extends down from the wall 18′ and whose bottom free end is lower than an upper end 14′ of the wall 13′. As should be apparent from FIGS. 7 and 8, the upper end 14′ of the wall is spaced from the wall 18′ so as to define an entrance opening or gap 17′ that allows the substance stored inside a container to enter into the member 10′. Also apparent from FIGS. 7 and 9, is that the wall 18′ contains a dispensing opening 19′. Although the functioning of the doser 10′ will be apparent later on, one should appreciate that the doser member 10′ has an internal volume space 16′ that is interrupted by the wall 15′. The space 16′ between the wall 11′ and the wall 15′ is in direct communication with the dispensing opening 19′ whereas the space between the wall 13′ and the wall 15′ is not in direct communication with the dispensing opening 19′ but is instead in direct communication with opening 17′. These openings 17′ and 19′ have different functions, with the opening 17′ serving to allow a container substance to enter into the space 16; whereas the opening 19′ allows any substance disposed inside space 16′ to exit from the doser member 10′. The doser member 10′ can be a one-piece member made of food grade plastic.
With reference to FIG. 11, there is shown another embodiment of a doser body 10″ arranged on a container 200. The doser member 10″ is installed inside the open end of the container body 200. The doser member 10″ is similar to the previous embodiment except that it does not utilize a upper wall 18′ and instead has an open upper end as shown in FIG. 11. As a result, the vertical separating wall 15″ is not connected at an upper end. Although not shown, the member 10″ can be axially retained inside the container 200 via a snap engagement, adhesive or ultrasonic welding, etc. between the wall 11″ and an inside surface of the container 200. As the member 10″ uses features similar to the previous embodiment, there are not further discussed herein
With reference to FIG. 12, there is shown another embodiment of a doser body 10′″ arranged on a container 200. The doser member 10′″ is installed inside the open end of the container body 200 as in the previous embodiment The doser member 10′″ is similar to the previous embodiment except that it is of shallower axial depth and therefore can dispense a lower volume of dispensable substance.
With reference to FIG. 13, there is shown an embodiment of a container package 1000 which utilizes a dispensing cap 20′ having an integrally formed cover 30′. The doser member can be of either type shown in FIG. 11 or 12. In this embodiment, the member 20′ has sift openings 22′ that allow the substance disposed in the doser to be sifted out during dispensing. When the package 1000 is not being used, a user or consumer can flip the cover 30′ to a closed position overlying the cap 20′. Although not shown, the cover 30′ can be retained in the closed position by, among other things, one or more projections engaging with the sift openings 22′. This retaining engagement would also seal off the openings 22′ and prevent any substances from leaking out of the openings 22′.
With reference to FIGS. 14A-14D, there is shown how the inventive doser functions in principle. An exemplary container 200 having a doser D can dispense a substance S container in the container 200. In the position shown in FIG. 14A, the doser D is shown installed on a container 200 containing a substance S. As expected, with the container 200 in a normal upright position, the substance S settles to the container bottom. To dispense a predetermined amount (or dose) of the substance S, a user or consumer grips the package container in his/her hand, needs to initially rotate the container to a substantially inverted position as shown in FIG. 14B. When this occurs, some of the substance S will pass into the doser D as shown in FIG. 14A. Indeed, when the user or consumer then rotates the container 200 to a substantially upright position as shown in FIG. 14C, one can see that the substance which passed into the doser in FIG. 14B has now settled into a space inside the doser D. This predetermined amount of substance can thus be characterized as a dispensable amount DA. In a final step for dispensing the dispensable amount DA (or dose), the user or consumer need only rotate the container to a substantially inverted position as shown in FIG. 14D. This will allow dispensing of only that which was inside the doser D—which exits from the dispensing opening DO. One should note that in the inverted position of FIG. 14D, some of the substance S will enter into the doser D during the dispensing. However, owing to the configuration of the doser D, only the dispensable amount DA will be dispensed, but advantageously, the dispensing position of FIG. 14D also results in doser D becoming charged with another dose D, as was the case in FIG. 14B.
With reference to FIGS. 15 and 16, there is shown another embodiment of an inventive doser 10IV mounted to a container 200 containing a dispensable substance S. In this embodiment, a covering or cap 30 is mounted to the doser 10IV and can be removed and reinstalled as needed. In the installed position shown in FIG. 15, the covering 30 has been slid onto the doser 10IV. In this position, the container package can be stored for later use while the doser 10IV remains protected from, among other things, collecting dust. When a user or consumer desires to use the container package, they need only remove (lift or slide off) the covering 30 to expose the doser 10IV. The covering 30 has a closed circular planar surface 31 and a circumferential or ring-shaped sidewall 32 that can sealing/frictionally engage with an outer circumferential surface of the doser 10IV. The covering 30 can be a one-piece member made of food grade plastic.
With reference to FIG. 17, there is shown another embodiment of a doser 10V. As with previous embodiments, the doser 10V can be installed on a container 200. The doser 10V comprises a cylindrical vertical side wall 11V that extends all the way around via wall 11AV so as to abut the container neck. A spaced between circumferential surfaces of these elements can be used to locate a seal S2 or sealing ring or projection (not shown). A bottom wall 12V is angled such that a dispensable substance disposed in an internal space 16V will flow down or settle toward a direction of the wall 11V. As should be apparent, the wall 11V extends from the bottom wall 12V to an upper wall 18V. The upper wall 18V includes a ring-shaped space 18CV that is shaped and sized to slid onto an open end of a container, and, in this example, is generally circular. In addition, the space 18CV is sized to be larger than the container opening so that an outer circumferential portion thereof forms a flange that sits atop of the container opening rim. The spaced 18CV is defined by circumferential surfaces which can be used to locate a seal S3 or sealing ring or projection (not shown). Alternatively or additionally, a seal S3 or sealing ring or projection (not shown) can be used between annular surfaces that define the space 18CV. The shape of the vertical wall 11V also functions to properly located and center the doser 10V inside the container opening. The doser 10V also utilizes a vertical separating wall 15V which extends down from the wall 18V and whose bottom free end is lower than an upper end 14V of the wall 13V. The upper end 14V of the wall 13V is spaced from the wall 18V so as to define an entrance opening or gap 17V that allows the substance S stored inside the container 200 to enter into the doser 10V in a manner similar to that described with reference to FIGS. 14A-14D. The wall 18V contains a dispensing opening 19V. Like previous embodiments, the doser 10V has an internal volume space 16V that is interrupted by the wad 15V. The space 16V between the wall 11V and the wall 15V is in direct communication with the dispensing opening 19V whereas the space between the wall 13V and the wall 15V is not in direct communication with the dispensing opening 19V but is instead in direct communication with opening 17V. These openings 17V and 19V have different functions, with the opening 17V serving to allow a container substance S to enter into the space 16V; whereas the opening 19V allows any substance disposed inside space 16V to exit from the doser 18V. The doser 10V also includes a central projection 18DV to which is mounted a rotatable disk 20″. The disk 20″ has gripping projections 23″ and either sifting openings or a pour opening or both (similar to that shown in FIGS. 19-21). Although not shown in FIG. 17, the disk 20″ can be rotated from the closed position shown in FIG. 17 to one or more opening positions wherein one or more openings in the disk 20′ are aligned with the dispenser opening 19V.
With reference to FIGS. 18-21, there is shown another embodiment of a doser 10VI. As with previous embodiments, the doser 10VI can be installed on a container 200. The doser 10VI is similar to that of FIGS. 7-10 but further includes a cylindrical wall 18AVI which extends from the vertical wall 11VI and extends all the way around so as to abut the container neck. A closure 40 is used to close off the container 200 and also axially retain in place the doser 10VI. The closure 40 includes a central projection 45 to which is mounted a rotatable disk 20′″. The disk 20′″ has gripping projections 23′″ as well as sift openings 21′″ and a pour opening 22′″. As shown in FIGS. 19-21 the disk 20′″ can be rotated (90 degrees) from the closed position shown in FIG. 19 (wherein a closed section of the disk 20′″ overlies the dispensing opening 19VI) to a pour position shown in FIG. 20 (wherein the pour opening 22′″ of the disk 20′″ overlies the dispensing opening 19VI) and alternatively rotated (90 degrees) to a sift position shown in FIG. 21 (wherein the sift opening 21′″ of the disk 20′″ overlie the dispensing opening 19VI). The projections 23′″ allow a user or consumer to more easily rotate the disk 20′″ relative to the body of the closure 40 so that the disk 20′″ can placed in each of the noted positions. In the embodiment of FIG. 18, it is desired and expected that the opening 49 of the closure 40 be aligned with the dispensing opening 19VI with the closure 40 being prevented from rotation when fully installed. However, it is also contemplated that the closure 40 can rotate from the position shown in FIG. 18, to a position wherein the opening 49 is not aligned with the dispensing opening 19VI. Such a system can be used as a tamper proof mechanism. With such a system, after an initial purchase by a user or consumer, in order to use the container package, they would be need to rotate the closure 40 (from a position closing off the opening 19VI) relative to the container 200 in order to place the opening 49 into alignment with the opening 19VI. Whether the package container is in either position shown in FIG. 20 or FIG. 21, it can be used in a manner similar to that shown in FIGS. 14A-14D.
With reference to FIG. 22, there is shown an exploded view of the embodiment of FIG. 18. As should be apparent, the doser 10VI is installable on a neck or open upper end 201 of the container 200. As with previous embodiments, the doser 10VI includes, among other things, an angled bottom wall 12VI and a vertical wall 11VI as well as a dispensing opening 19VI arranged on a upper wall 18VI. The closure 40 includes a cylindrical side wall 41 having a cylindrical inner surface 43, as well, as an upper wall 43 having a surrounding flange 44 and a central retaining projecting 45. The central projection 45 is used to retain and centrally mount a rotatable disk 20′″.
With reference to FIGS. 23 and 23A, there is shown one non-limiting way in which a doser 10VII, similar to that used in FIG. 18, can be retained on the container neck 201. The vertical wall 11AVII can include one or more circumferential projections P1 that form a snap engagement with one or more circumferential projections P2 arranged on the container neck 201. These projections P1 and P2 form a retaining arrangement RA. It is also contemplated the projections are replaced with a projection and recess engagement or by merely using a sealing ring between the walls 11VII and 201. Such a retaining arrangement RA can be used on any of the embodiments disclosed herein, where practical.
With reference to FIGS. 24-31, there is shown another non-limiting embodiment of a package container which utilizes a container 200 of the type described previously and a doser 10VI of the type used in FIG. 18. However, this embodiment utilizes a closure 20IV that is of simpler configuration. The closure 20IV has the shape of a cap and can optionally include a visual indicator arrow VIA which informs the user or consumer that they need to rotate the closure relative to the container 200 in order to place the same in each of a closed position (see FIGS. 28 and 29) and each of a sift position (see FIGS. 26 and 27) and a pour position (see FIGS. 24 and 25). The closure 20IV is rotatable, but is also axially and non-removably retained on the container 200 via engagement between tapered retaining projections RP1 and RP2 (see FIG. 31). As should be apparent from FIGS. 24 and 25 the closure 20IV can be rotated (90 degrees) from the closed position shown in FIGS. 28 and 29 (wherein a closed section of the closure overlies the dispensing opening 19VI) to a pour position shown in FIGS. 24 and 25 (wherein the pour opening 22IV overlies the dispensing opening 19VI) and alternatively rotated (90 degrees) to a sift position shown in FIGS. 26 and 27 (wherein the sift openings 21IV overlie the dispensing opening 19VI). In the embodiment of FIGS. 24-30, it is desired and expected that the closure will be in the position shown in FIGS. 28 and 29 prior to purchase—with the container package or the closure portion thereof being covered with a tamper proof covering such a shrink wrap. As is apparent from FIG. 30, the closure 20IV also includes a sidewall 23IV and an upper wall 24IV. The upper wall 24IV includes the pour opening 22IV and the sift openings 21IV and an inner circumferential surface of sidewall 23IV includes the circumferential projection RP2.
FIG. 32 shows a top view of a container package according to another embodiment of the invention. This embodiment is similar to that of FIG. 24 and additionally utilizes a visual indicator VI to inform a user or consumer of the rotation position of the closure 20IV relative to the container 200′ that will align with the dispensing opening of the doser (not shown in FIG. 32). The rotation position of FIG. 32 is a closed or non-dispensing position similar to that shown in FIGS. 28 and 29.
The devices described above can also utilize one or more features disclosed in the prior art documents expressly incorporated by reference herein. Furthermore, one or more of the various parts of the device can preferably be made as one-piece structures by e.g., injection molding, when doing so reduces costs of manufacture. Non-limiting materials for all of the parts include synthetic resins such as those approved for food product packaging. The container can, for example, be made of Propylene while the closure can, for example, be made of either PET or PP. Furthermore, the invention also contemplates that any or ail disclosed features of one embodiment may be used on other disclosed embodiments, to the extent such modifications function for their intended purpose.
At least because the invention is disclosed herein in a manner that enables one to make and use it, by virtue of the disclosure of particular exemplary embodiments of the invention, the invention can be practiced in the absence of any additional element or additional structure that is not specifically disclosed herein.
