1. Field of Invention
This invention relates to refillable containers and more particularly to an apparatus, system, and method for delivering refill liquid to a destination container.
2. Description of Related Art
Containers used for carrying and dispensing liquids such as personal care or cosmetic products, for example, are not generally intended to be refilled. Such containers may be expensive to make and may include rigid or semi rigid bodies that are ergonomically designed for users. Once empty, such containers are often thrown away and a user is required to purchase a new container, in order to obtain additional product. This wastage of empty containers may result in both financial and environmental costs.
It may be desirable to refill such containers such that they may be used numerous times before a user is required to purchase a new container. One method of refilling containers involves the use of a transport container. However, conventional transport containers have various problems. For example, conventional transport containers may be expensive to make or difficult to use. For example, conventional transport containers may be difficult to fill or difficult to empty or dispense from.
In accordance with one aspect of the invention, there is provided an apparatus for delivering refill liquid to a destination container. The apparatus includes a deformable transport container having an opening for receiving the refill liquid, and an adaptor including an inlet, an outlet, and a passage extending between the inlet and the outlet. The inlet is removably receivable at the opening of the transport container such that when the inlet is received at the opening, the inlet is operable to receive a flow of the refill liquid through the opening from the transport container and to channel the flow through the passage to the outlet, the outlet being operable to dispense the refill liquid into the destination container, and when the inlet is not received at the opening, the transport container is operable to receive the refill liquid through the opening.
The apparatus may further include a retainer coupled between the adaptor and the transport container for retaining the adaptor with the transport container.
The retainer may include a flexible strap.
The flexible strap may be rotatably coupled to the transport container such that the adaptor is free to rotate about the opening.

Referring to
The transport container 12 shown in
The deformable bag 13 may be made of a deformable material, such as plastic, configured to hold refill liquid. In some embodiments, the deformability of the deformable bag 13 may facilitate compression of the transport container 12 for storage when not filled with refill liquid. Accordingly, in some embodiments, the transport container 12 may be more easily and cost effectively stored and shipped when compared to non-deformable containers. Further, the deformable bag 13 may be fabricated from less material than would be required to fabricate a more rigid container having comparable volume and thus may be less costly to produce.
In some embodiments, the nozzle 14 may be made of a rigid material, such as plastic. In the embodiment shown, the nozzle 14 includes a threaded portion 80.
The adaptor 18 includes an inlet 20, an outlet 22, and a passage 24 extending between the inlet and the outlet. The inlet 20 is removably receivable at the opening 16. In the configuration shown in
In some embodiments, the refill apparatus 10 includes a flexible strap 28 coupled between the adaptor 18 and the transport container 12. The strap 28 acts as a retainer for retaining the adaptor 18 with the transport container 12, when the adaptor 18 is not received in the opening 16. In the embodiment shown, the flexible strap 28 and the adaptor 18 are formed from a unitary body of semi-rigid material, such as for example, plastic. In the embodiment shown, the flexible strap 28 may be sufficiently thin to provide flexibility to the strap 28. In other embodiments, the flexible strap 28 may be separate from the adaptor 18 and may comprise for example, string, or wire. In some embodiments, the flexible strap 28 may be omitted.
The flexible strap 28 includes a loop or annular portion 30 which is configured to rotatably couple to the transport container 12 by encircling the nozzle 14 and being retained by a collar 32 of the nozzle 14. The flexible strap 28 is, thus, rotatably coupled to the transport container 12 such that the adaptor 18 is free to rotate about the opening 16.
Referring to
The process 200 begins at block 202, which involves receiving a refill liquid in the transport container 12 through the opening 16 of the transport container. In some embodiments, the opening 16 of the transport container 12 may be large enough to receive a nozzle of a bulk source, which may facilitate easier, spill free, filling. Block 204 involves closing the opening 16 of the transport container 12 to configure the transport container for transport. For example, the user may close the opening 16 with a closure, such as a cap (e.g. cap 26 shown in
Block 208 involves removably receiving the inlet 20 of the adaptor 18 at the opening 16 of the transport container 12. In some embodiments block 208 involves the user inserting the adaptor 18 into the opening 16. Next, block 210 involves receiving the outlet 22 of the adaptor 18 at an opening of the destination container. In some embodiments, the opening of the destination container may be smaller than the opening of the transport container and the outlet of the adaptor may be configured to fit within the opening of the destination container, which may faciltiate easy, spill free, filling of the destination container. Block 212 involves causing the refill liquid to flow from the opening 16 of the transport container 12 through the passage 24 extending from the inlet 20 to the outlet 22 of the adaptor 18 to dispense the refill liquid into the destination container. Block 214 involves removing the inlet 20 of the adaptor 18 from the opening 16 and retaining the adaptor 18 with the transport container using the retainer 28.
In some embodiments, after completing block 214 the process may return to block 202. Accordingly, in some embodiments, because the adaptor 18 is removable from the opening 16, the transport container 12 may be able to be re-used for multiple iterations of blocks 202-214.
Further, in some embodiments, by using the above process, which employs an adaptor, a user may be able to quickly fill a transport container through a relatively large opening and to dispense from the transport container into a small opening in a destination container by dispensing the refill liquid through a relatively small outlet of an adaptor configured to be received in the opening of the destination container.

In the embodiment shown in
The opening 16 may be sized large enough to accommodate receiving the nozzle 64 therewithin and the nozzle 64 may be sized large enough to allow the refill liquid to be pumped into the transport container 12 within about 1 minute. In one embodiment, the opening 16 has a diameter of about 0.385 inches and the nozzle 64 has an outer diameter of about 0.3 inches and an inner passage having a diameter of about 0.25 inches. In other embodiments, the opening 16 may be sized differently and/or the nozzle 64 may be sized differently. In some embodiments, the diameter of the opening 16 may correspond to a capacity of the transport container 12. For example, in the embodiment shown, the transport container 12 has a capacity of about 350 mL and the diameter of the opening 16 is about 11 mm. In some embodiments, the diameter of the opening 16 may differ. For example, in various embodiments, the transport container 12 may be configured to hold about 1 L and the diameter of the opening 16 may be about 22 mm, for example.
In some embodiments, because the nozzle 64 is receivable within the opening 16, a user may be able to pump the refill liquid into the transport container 12 without risking spillage of the refill liquid.
In some embodiments, the bulk source 60 may include a hand pump, a foot pump, a powered pump such as an electric pump, vacuum pump, or any other type of pump.
The transport container 12 may deform while being filled to accommodate refill liquid as it is pumped into the transport container, as shown in
Once the transport container 12 is filled with the refill liquid, the transport container 12 may be configured for transport by closing the opening 16 using a closure, as per block 204 of the process 200 shown in
The refill apparatus 10 may be transported, in the configuration shown in
In one embodiment, after transporting, and once a user is ready to dispense the refill liquid from the transport container 12, the user may configure the transport container to receive the inlet 20 of the adaptor 18 by removing the cap 26 from the nozzle 14 to re-open the opening 16 as described in block 206 shown in
The user may then cause the inlet 20 of the adaptor 18 to be removably received at the opening 16, as described at block 208 of the process 200 shown in
In other embodiments, an inlet of an adaptor may be received at the opening 16 in other ways. For example, an inlet of an adaptor may have an inner diameter that corresponds to the outer diameter of the nozzle 14 and the inlet may be received at the opening 16 by being placed on the nozzle 14. In some embodiments, an adaptor may included a threaded portion that corresponds to and engages with the threaded portion 80 of the nozzle when the adaptor is received at the opening 16. However, in some embodiments, sizing the inlet 20 to fit within the opening 16 may allow the adaptor 18 to be smaller and thus may provide reduced costs compared to embodiments where the inlet 20 is sized to surround the nozzle 14.
In the embodiment shown, the inlet 20 includes a tapered portion 100, complementary to the opening 16 that has an outer diameter that widens to a diameter about equal to a diameter of the opening 16. In one embodiment, to insert the inlet 20 of the adaptor 18 into the opening 16, a user may push the tapered portion 100 into the opening 16 such that the inlet 20, when received in the opening 16 is retained by a friction fit within the opening 16. For example, in one embodiment, the tapered portion 100 may allow the user to more easily centre the inlet 20 when inserting the inlet 20 into the friction fit within the opening 16.
In the embodiment shown, the adaptor 18 includes a flange 90 configured and disposed to abut the nozzle 14 when the inlet 20 is received at the opening 16 of the transport container 12 and thereby limit the depth to which the inlet 20 can be inserted into the opening 16. In the embodiment shown, the flange 90 comprises a ring that encircles the passage 24 and is disposed between the inlet 20 and the outlet 22. In some embodiments, the flange 90 may have an outer diameter at least as large as the outer diameter of the nozzle 14 and, thus, be configured to be gripped by a user when the user wishes to remove the adaptor 18 from the opening 16.
With the inlet 20 removably received in the opening 16, the inlet 20 is operable to receive a flow of refill liquid through the opening 16 from the transport container 12 and to channel the flow through the passage 24 to the outlet 22, as shown by arrow 102 shown in
In the embodiment shown, before causing the refill liquid to flow through the adaptor 18, the outlet 22 of the adaptor 18 has been removably received at the opening 120 of the cap 122 of the destination container 124, as described in block 210 of the process 200 shown in
The cap 122 of the destination container 124 defines the opening 120 which narrows to a narrow portion 128. The outlet 22 includes a frustoconical portion 130 and a cylindrically shaped extension 132 extending therefrom. In the embodiment shown, the extension 132 has been inserted through the narrow portion 128 of the opening 120 such that the extension 132 extends past the narrow portion of 128 of the opening 120 into the destination container 124.
The cylindrical shape of the extension 132 may facilitate the extension extending past the narrow portion 128 of the opening 120, while retaining the same diameter of the passage 24. The ability of the extension 132 to extend into the narrow portion 128 of the opening 120 may result in the extension being less likely to slip out of the narrow portion 128 of the opening 120 during filling of the destination container 124. Keeping the same diameter as the extension 132 extends past the narrow portion 128 of the opening 120 may allow for refill liquid to flow more quickly and easily through the passage 24.
In the embodiment shown in
The extension 132 has an outer diameter that is smaller than a diameter of the opening 120 such that a gap 91 is formed between the extension 132 and the cap 122 at the narrow portion 128 of the opening 120 when the extension 132 is received therein.
Further, in the embodiment shown in
In the embodiment shown, the gaps 91 and 92 may allow air that is displaced by refill liquid being dispensed into the destination container 124 to flow out of the destination container 124. Accordingly, the gaps 91 and 92 may allow for quick filling of the destination container 124.
After the outlet 22 has been received in the opening 120 of the cap 122 of the destination container 124, a user may cause refill liquid 133 to be channeled from the opening 16 of the transport container 12 through the passage 24 to the outlet 22 of the adaptor 18 and into the destination container 124, as described in block 212 of the process 200 shown in
In one embodiment, the user may cause the refill liquid to be channeled from the opening 16 of the transport container 12 through the passage 24 to the outlet 22 of the adaptor 18 by squeezing the deformable bag 13 to force the refill liquid to flow in the direction shown by the arrow 102.
Once the destination container 124 is filled, or when no more refill liquid can be dispensed from the transport container 12, the user may remove the adaptor 18 from the opening 16 and clean the adaptor 18 and/or the transport container 12. In some embodiments, the rotatable connection of the flexible strap 28 may facilitate rotation of the adaptor 18 about the transport container 12 to help disconnect the adaptor 18 from the opening 16, when the user wishes to remove the adaptor 18 from the opening 16.
When the user is ready to fill another destination container or to refill the destination container 124, the user may return to block 202 of the process 200 shown in
In some embodiments, where some refill liquid remains in the transport container 12 after completing block 214 of the process 200 shown in
Still referring to
In some embodiments, use of the friction fit may allow a user to quickly insert and remove the inlet 18 from the opening 16. Further the friction fit may allow the inlet 20 and the opening 16 to be generally smooth, which may allow for ease of cleaning. This may be particularly important when the refill liquid is a personal care product that must be kept clean and free of contamination. In some embodiments, using a friction fit may allow for lower manufacturing costs than with other connections for retaining the inlet 18 in the opening 16.
In other embodiments, the inlet 20 may be retained in the opening 16 by another means, such as by a threaded connection or by a snap fit connection. A threaded connection or a snap fit connection may be preferred in embodiments where a pressure in the refill liquid during refilling results in a force on the inlet 20 that could overcome the friction force of the friction fit retaining the inlet 20 within the opening 16.

In the embodiment shown in
In the embodiment shown, the refill apparatus 150 also includes a flexible strap 164 generally similar to the flexible strap 28 shown in
