Container for storing and dispensing material

Abstract: A container (10) is provided for storing and dispensing materials such as liquids or powders, having a first compartment (12) having a first end (16) and side walls (18a) and a second compartment (14) disposed within the first end (16) of the first compartment (12) such that a gap exists between an outer wall (14a) of the second compartment (14) and the side wall portion (18a) of the first compartment (12), with the gap (20) being wide enough for material to pass therethrough. The container (10) can be squeezed, inverted or shaken to force an amount of material from the first compartment (12) and into the second compartment (14) through the gap (20). The second compartment (14) may be a friction fit or snap fit within the first end (16) of the first compartment (12), while retaining the gap (20) between the outer wall (14a) of the second compartment (14) and the side wall portion (18a) of the first compartment (12). The container (10) further has a lid (28) for closing and opening the container (10), and a plug (30) disposed with the lid (28), such that when the container (10) is closed, the plug (30) is inserted into the second compartment (16) to control the level of material which is retained in the second compartment (14).

Description: The present invention relates to a container for storing and dispensing materials, such as liquids and powders, and to a method of storing and dispensing materials, and to a method of treating fingernails. Liquids or powders such as cooking oil, baby powder, fingernail polish remover, and jewelry cleaner are often stored in containers which provide for dispensing the liquid into a separate container or onto cloth or cotton balls before use. Thus, there is always the possibility of spillage of the material at some time during the dispensing process. In addition, the prior art containers lack any compartment which provides for the pre-measuring and retaining an amount of material which is dispensed for each particular application. Accordingly, a number of containers have been previously proposed to eliminate or reduce the spillage which typically results from these prior containers. For example, Duceppe, U.S. Patent No. 4,282,891, discloses a cylindrical, flat-bottomed container having a removable cover for holding fingernail polish remover. A sponge pad having a centrally-located finger receiving means is disposed within the container. Fingernail polish remover is absorbed by the sponge, so that upon insertion of the finger into the finger receiving hole and rotation of the finger, the inner surface of the finger receiving hole aids in removing fingernail polish from the fingernail. This avoids the need for special brushes for removing the fingernail polish. The container, however, has suffered the disadvantage that the fingernail polish remover must be periodically poured into the container to replace that which has been used. Thus, the device is not entirely self-contained and does not completely eliminate the spillage problem. Zeeni and Duceppe, U.S. Patent No. 4,964,372 illustrates a container having first and second compartments, with a liquid metering valve dividing the two compartments. The second compartment has squeezable side walls whereby, upon squeezing, an amount of liquid is supplied to the first compartment to fill a liquid absorbing sponge with liquid nail polish remover. However, with the Zeeni/Duceppe container, a separate mechanical device is needed to force material from the second compartment into the first compartment, or the first compartment must have a slit or hole for receiving liquid from the second compartment. Thus, if problems arise with the metering valve, the function of the container is reduced to that of the prior art containers, and the first compartment cannot be used to retain the specific amount of liquid to be dispensed, and the spillage problem continues with the second compartment. Furthermore, since the first compartment must have a hole or slit to receive the valve or liquid directly, it could never serve as a storage compartment to retain a pre-measured amount of material for future use. US-A-4,106,673 describes an apparatus for measuring and dispensing liquids, but which is not however suitable for serving as a storage compartment to retain a pre-measured amount of material. Viewed from one aspect, the present invention provides a container for storing and dispensing material comprising: a first compartment having a first open end portion and a sidewall portion; a second compartment, having a wall and a top edge, disposed within the first end portion of said first compartment such that a gap exists between an outer wall of said second compartment and the sidewall portion of said first compartment, the gap being wide enough for material to pass therethrough, into said second compartment; and a lid for closing and opening said container; characterised in that upon forcing an amount of material from said first compartment into said second compartment through the gap, said material passes over the peripheral top edge of said second compartment; and in that a plug is disposed within said lid, whereby when said container is closed, said plug is inserted in said second compartment to retain the amount of material which is in said second compartment. The second compartment may preferably be a friction fit or snap fit within the first end of the first compartment, while retaining the gap between the outer wall of the second compartment and the side walls of the first compartment. In one embodiment in which means are provided for forcing an amount of material through the gap, the material is forced from the first compartment into the second compartment by squeezing the side wall portion of the first compartment. In another embodiment, the material is forced from the first compartment into the second compartment by shaking and/or inverting the container. In the illustrated embodiment, the container is one for treating fingernails, and comprises a first compartment having a first open end and side walls, a second compartment disposed within the first end of the first compartment such that a gap exists between an outer wall of the second compartment and side walls of the first compartment, the gap being wide enough for a liquid to pass therethrough, over the peripheral top edge of the second compartment and into the second compartment. A liquid absorbing member is disposed in the second compartment, with a finger receiving means defined within the liquid absorbing member. Means are provided for forcing an amount of liquid fingernail polish remover from the first compartment and into the second compartment through the gap. Viewed from another aspect, the present invention provides a method for storing and dispensing material comprising the steps of: providing a container having a first compartment having a first open end and sidewall, a second compartment, having a wall and a top edge, disposed within the first end of said first compartment such that a gap exists between an outerwall of said second compartment and the sidewall portion of said first compartment, the gap being wide enough for material to pass therethrough; at least partially filling said first compartment with material; and providing a lid for closing and opening said container; characterised by the steps of providing said lid with a plug disposed therein; forcing an amount of material through the gap, over the peripheral top edge of said second compartment and into said second compartment; and closing said container such that said plug is inserted into said second compartment to retain the amount of material which is in said second compartment. Preferably the material is a liquid for treating fingernails and the method further comprises the steps of placing a liquid absorbing member having a finger receiving means in the second compartment, and inserting at least an end of a finger in the finger receiving means for treating a fingernail. An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, wherein:- Figure 1 is a perspective view of a first embodiment of a container according to a preferred embodiment of the present invention; Figure 2 is a partial vertical cross-section of the container according to the preferred embodiment of the present invention illustrated in Figure 1; Figure 2a (not drawn to scale) is an enlargement of a section of the preferred embodiment of Figure 1; Figure 3 is a partial vertical cross-section of the container in use; and Figure 4 is a top perspective view of the container. The preferred embodiment illustrated in Figures 1 and 2, comprises a fingernail treating container, designated generally by the reference numeral 10 having a first lower compartment 12 and a second upper compartment 14. As shown in Figures 1 and 2, the lower compartment 12 has a first end portion 16 which includes an opening 16a and side wall portion 18a. As illustrated, the upper compartment 14 is disposed within opening 16a in the first end of compartment 12, such that a gap 20 exists between outer walls 14a of the upper compartment and the side wall portion 18a of the first end of the lower compartment with the corner of bottom wall portion 14b grasping the side wall portion 18a. The upper compartment 14 may be friction fit within the first end of the lower compartment as illustrated in Figure 1, or can be snap fit. The lower compartment 12 is at least partially filled with liquid nail polish remover or other material. As seen in Figures 1-4, the upper compartment may contain a liquid absorbing sponge member 22 having defined therein a generally centrally located finger receiving hole 24. The finger receiving hole may advantageously be formed from a plurality of intersecting slits 26, as shown in Figure 4. The upper compartment 14 is constructed generally as disclosed in U.S. Patent No. 4,282,891, which is hereby incorporated by reference, except that in compartment 14, the bottom wall portion 14b is completely solid without any holes or slits. Referring now to Figure 2, there is shown a partial cross-section of the upper compartment of a fingernail polish removing device according to the illustrated embodiment. As shown in this figure, a removable lid 28 is threadably disposed atop the upper compartment 14. As shown in Figure 2, disposed within this upper lid 28 is a plug 30. The plug 30 serves to retain the level of material which is stored in the upper compartment. For example, upon screwing the lid onto the top of the upper compartment 14, the plug 30 is forced into the upper compartment, thereby retaining the level of fluid or other material in the upper compartment. The lower compartment 12 may be formed from a squeezable material such as soft plastic so that upon squeezing the lower side walls of the lower compartment 12, nail polish remover or other material is forced to flow, as shown in Figure 2a (not drawn to scale - arrows indicating direction of flow) from the lower compartment 12, through the gap 20, over the top edge of the upper compartment 14c, and into the upper compartment 14, and thereby soaking the sponge 22 with material. The lower compartment 12 may also be formed from glass or other material, such that upon inverting and/or shaking the container, material such as nail polish remover is forced to flow from the lower compartment 12, through the gap 20 and into the upper compartment 14. After using the upper compartment to dispense the polish remover by inserting a finger into finger receiving hole 24, the lid can be placed on top of the container 10, screwed on to upper compartment 14 and plug 30 inserted into the upper compartment to retain the amount of material needed for future applications. Thus, in at least preferred embodiments, there is provided a bi-compartmentalized container which includes a non-mechanical means for forcing material from the first compartment into the second compartment, without forming a slit or hole in the bottom of the second compartment, with the first compartment having an opening for receiving the second compartment; and there is provided a lid for closing and opening the container, having a plug disposed within the lid, whereby when the container is closed, the plug is inserted in the second compartment to control the level of material which is retained in the second compartment; and there is provided a container wherein the material may be replenished in the second compartment by squeezing the side walls of the first compartment; and there is provided a container wherein the material may be replenished in the second compartment by inverting and/or shaking the container; and there is provided a bi-compartmentalized container for treating fingernails having a liquid absorbing member disposed in the second member, a finger receiving means defined within the liquid absorbing member, and a non-mechanical means for forcing an amount of liquid from the first compartment into the second compartment. It should become obvious to those skilled in the art that this invention is not limited to the preferred embodiments shown and described. For example, the upper and lower compartments of the container may take on many different shapes. Additionally, the container may be used to store and dispense various types of material such as liquids or powders, and depending upon the application, a liquid absorbing member may not be necessary.
