Description
Technical Field
The present disclosure relates generally to a dual-end container for use in applying personal products, such as cosmetic products. More specifically, a dual end container with a compact integrated mechanism for selectively extending and retracting a first product without movement of a second product is disclosed.
Background
The cosmetic industry is a large industry and offers numerous products to consumers. Many consumers use a variety of cosmetic products throughout the day. These consumers therefore carry their preferred products in their personal items, such as handbags. Typically, each individual product is contained in its own container, but there are some containers containing two or more cosmetic products.
However, conventional dual cosmetic containers are bulky because they require two different mechanisms, each of which occupies a significant amount of space in the container.
Accordingly, there is a need for an improved dual end container.
Disclosure of Invention
In one example, a dual end container includes a first cup, a second cup facing in opposite directions and aligned along a longitudinal axis of the dual end container, and a drive member assembly positioned between the first cup and the second cup and adapted to selectively move the first cup and the second cup, wherein the drive member assembly includes a first drive member having a first threaded member coupled to the first cup, the first threaded member having an interior volume, and a second drive member having a second threaded member coupled to the second cup and disposed at least partially within the interior volume of the first threaded member.
In another example, a dual ended container includes a drive member assembly including a first drive member having an interior volume formed therein having a first female thread and a second drive member having an interior volume formed therein having a second female thread, the second drive member being coupled with the first drive member to form the drive member assembly, a first cup coupled to a first side of the first drive member, the first cup having an interior volume and an outer surface having a first male thread formed thereon, and a second cup coupled to a second side of the drive member, the second cup having an outer surface having a second male thread formed thereon, wherein the outer surface of the second cup has a diameter smaller than the diameter of the interior volume of the first cup and the second cup is at least partially received within the interior volume of the first cup.
In yet another example, a method for filling a dual end container includes filling a first cup of a first dual end container portion with a first product, filling a second cup of a second dual end container portion with a second product, and coupling the first dual end container portion to the second dual end container portion.
In summary, the present disclosure relates generally to a dual end container for products, such as cosmetic products. More specifically, a dual end container with a compact integrated mechanism for selectively extending and retracting a first product or product applicator while a second product or product applicator is not moving is disclosed. The dual end container includes a first cup, a second cup at least partially received within the first cup, and a drive member assembly between the first cup and the second cup. The first cup has a first male thread, the second cup has a second male thread, and the first drive member has a first female thread, and the second drive member has a second female thread. The first male thread interacts with the first female thread to extend and retract the first cup. The second male thread interacts with the second female thread to extend and retract the second cup.

Detailed Description
The present disclosure relates generally to a dual-end container for use in applying personal products, such as cosmetic products. The dual end container has a compact integrated mechanism for selectively extending and retracting a first product or first applicator from one end of the container while a second product or second applicator disposed at an opposite end of the container does not move and vice versa. The dual end container includes a first cup, a second cup, and a drive member assembly disposed between the first cup and the second cup, including a first drive member and a second drive member. The first cup has a first male thread, the second cup has a second male thread, the first drive member has a first female thread, and the second drive member has a second female thread. The first male thread interacts with the first female thread to extend and retract the first cup without the second cup moving. The second male thread interacts with the second female thread to extend and retract the second cup without the first cup moving. This selective extension enables the consumer to select a product or applicator to be used and advance only that product or applicator without having to extend another product or applicator.
Fig. 1A is a front view of a dual end container 100 according to one example. The dual-ended container 100 is configured to contain a first product 124 and a second product 126. The dual end container 100 has a longitudinal axis 102.
Fig. 1B is a schematic cross-sectional view of the dual end container 100 of fig. 1A. The dual end container 100 includes a drive member 110, the drive member 110 being located along the longitudinal axis 102 between a first cup 112 and a second cup 114. The first shell 116 surrounds the first cup 112 and the second shell 118 surrounds the second cup 114. The first cap 120 is coupled with the first housing 116, and the second cap 122 is coupled with the second housing 118. The first cup 112 is configured to hold a first product 124 and the second cup 114 is configured to hold a second product 126. For example, the first cup 112 may include a product container portion 130 for holding the first product 124. Likewise, the second cup 114 may include a product container portion 132 for holding the second product 126.
The dual-ended container 100 includes a threaded region 123 that moves one or both of the first cup 112 and the second cup 114 along the longitudinal axis 102 when relative movement is provided between the drive member 110 and either the first cup 112 or the second cup 114. The first cup 112 is adapted to move along the longitudinal axis 102 in an enlarged interior region 125 of the first housing 116. Likewise, the second cup 114 is adapted to move along the longitudinal axis 102 in the enlarged interior region 127 of the second housing 118. The first housing 116 may include a stop mechanism, such as a first stop 128, the first stop 128 interacting with a shoulder 134 extending radially outward from the product container portion 130. As the first cup 112 moves away from the drive member 110 along the longitudinal axis 102, the shoulder 134 contacts the first stop 128 to prevent additional movement of the first cup 112 along the longitudinal axis 102. Likewise, the second housing 118 may include a stop mechanism, such as a second stop 129, that the second stop 129 interacts with a shoulder 136 extending radially outward from the product container portion 132. As the second cup 114 moves away from the drive member 110 along the longitudinal axis 102, the shoulder 136 contacts the second stop 129 to prevent additional movement of the second cup 114 along the longitudinal axis 102.
Fig. 2A is an exploded cross-sectional view of the dual end container 100 of fig. 1B. Fig. 2B is an exploded isometric view of the dual end container 100 of fig. 1B. Fig. 2C is an enlarged cross-sectional view of the drive member 110. As shown in fig. 2A-2C, the drive member 110 is a hollow body surrounding an interior volume 234 and has a recess/cutout 236 toward the proximal end. Further, the drive member 110 has a first threaded member 230 near the proximal portion or first side and a second threaded member 232 near the distal portion or second side. A portion of the first cup 112 is received in the interior volume 234 in a proximal portion of the drive member and a portion of the second cup 114 is received in the interior volume 234 in a distal portion of the drive member 110. As shown in fig. 2A-2B, the first cup 112 has an interior volume 213 and an exterior surface 215, the exterior surface 215 having a first male thread 217 formed thereon. The second cup 114 has an interior volume 219 and an outer surface 221, the outer surface 221 having a second male thread 223 formed thereon. The diameter of the outer surface 221 is smaller than the diameter of the interior volume 213 such that the second cup 114 is at least partially received within the interior volume 213 of the first cup 112. The first threaded member 230 engages with the first male thread 217 and the second threaded member 232 engages with the second male thread 223.
The first and second male threads 217 and 223 may be right-handed threads, the first and second male threads 217 and 223 may be left-handed threads, the first male thread 217 may be right-handed threads, and the second male thread 223 may be left-handed threads, or the first male thread 217 may be left-handed threads, and the second male thread 223 may be right-handed threads.
Each of the drive member 110, the first cup 112, the second cup 114, the first housing 116, the second housing 118, the first cap 120, and the second cap 122 may be made of plastic or any other suitable material. In one example, the first product 124 and the second product 126 may be cosmetic products such as lipsticks, lip colors, foundations, mascaras, eyeliners, eye shadows, or blushers. Additionally, one or both of the first and second products 124, 126 may be replaced with a cosmetic applicator, such as a sponge or brush. In another example, the first product 124 and the second product 126 may be personal care products, such as deodorants. In yet another example, one or both of the first product 124 and the second product 126 can be skin care products. In even further examples, the first product 124 and the second product 126 may be hair care products or pet products. In still further examples, the first product 124 and the second product 126 may be dental products.
The first cap 120 and the second cap 122 are removable from the first housing 116 and the second housing 118, respectively. As shown in fig. 2A and 2B, the first cap 120 has a flat top surface 120A, while the second cap 122 has a tapered top surface 122A. According to other alternative examples, the first cap 120 and the second cap 122 may have other desired shapes. The first cap 120 may be sized to removably snap fit to the first housing 116 or to have an interference fit with the first housing 116. The second cap 122 may be sized to loosely cover the second housing 118. Because the second cap 122 loosely covers the second housing 118, the second cup 114, and thus the second product 126, may not be accidentally actuated while the second cap 122 is still above. In order for the second product 126 to actuate and translate along the longitudinal axis 102 of the dual-end container 100, the consumer must intentionally remove the second cap 122.
The drive member 110 is engaged with the first and second housings 116, 118 such that the drive member 110 is rotatable relative to the first and second housings 116, 118, respectively. In operation, when the first housing 116 is rotated relative to the drive member 110 and the first cup 112 is rotationally constrained relative to the first housing 116, the first cup 112 moves axially along the longitudinal axis 102 of the dual end container 100. Alternatively, when the drive member 110 is rotated relative to the first housing 116 and the first cup 112 is rotationally constrained relative to the first housing 116, the first cup 112 moves axially along the longitudinal axis 102 of the dual end container 100. More specifically, rotating the first housing 116 or the drive member 110 causes the first male threads 217 to engage with the first threaded member 230. Rotating the first housing 116 or the drive member 110 in a first direction (e.g., toward the left side of the page, as shown in fig. 1A-2C) causes the first cup 112 and the first product 124 to extend longitudinally out of the dual-end container 100, while rotating the first housing 116 or the drive member 110 in a second direction (e.g., toward the right side of the page, as shown in fig. 1A-2C) causes the first cup 112 and the first product 124 to retract longitudinally into the dual-end container 100.
Similarly, when the second housing 118 is rotated relative to the drive member 110 and the second cup 114 is rotationally constrained relative to the second housing 118, the second cup 114 moves axially along the longitudinal axis 102 of the dual end container 100. Optionally, when the drive member 110 rotates relative to the second housing 118 and the second cup 114 is rotationally constrained relative to the second housing 118, the second cup 114 moves axially along the longitudinal axis 102 of the dual end container 100. Rotation of the second housing 118 or the drive member 110 causes the second male threads 223 to engage with the second threaded member 232. Rotating the second housing 118 or drive member 110 in a first direction, e.g., clockwise (toward the left side of the page, as shown in fig. 1A-2C), causes the second cup 114 and second product 126 to extend longitudinally out of the dual-end container 100, while rotating the second housing 118 or drive member 110 in a second direction, e.g., counterclockwise (toward the right side of the page, as shown in fig. 1A-2C), causes the second cup 114 and second product 126 to retract longitudinally into the dual-end container 100.
One or more of the first stop 128, the second stop 129, and the groove 236 may prevent disassembly of components of the dual end container 100. When the first cup 112 is extended by rotation of the first housing 116 relative to the drive member 110, the first cup 112 may be prevented from over-extending from the dual end container 100 by the first stop 128 of the first housing 116. The first stop 128 is an inwardly extending projection of the first housing 116 through which the first cup 112 cannot pass. Similarly, second cup 114 may be prevented from over-extending from dual end container 100 by second stop 129 of second housing 118. The second stop 129 is an inwardly extending projection of the second housing 118 through which the second cup 114 cannot pass. Additionally, the groove 236 shown in fig. 2C attenuates the reaction force of the first threaded member 230. In other words, the groove 236 prevents the first cup 112 from forcing the first housing 116 and the drive member 110 apart.
Fig. 3 is a schematic cross-sectional view of a dual end container 300 according to another example. The dual-ended container 300 is similar to the dual-ended container 100 except that the second cup is replaced with a vial 340. As shown in fig. 3, the first cup 312 holds a vial 340. The vial 340 may contain a second product. For example, the vial 340 may contain a lip gloss, perfume, skin care solution, dental solution, pet care solution, or other product. Optionally, the second cup 314 may be configured to hold a cartridge for dispensing product. The vial 340 or optional cartridge may be plastic, glass, or any other suitable material.
In operation, when first housing 316 is rotated relative to drive member 310 and first cup 312 is rotationally constrained relative to first housing 316, first cup 312 moves axially along longitudinal axis 302 of dual-end container 300. Alternatively, when drive member 310 rotates relative to first housing 316 and first cup 312 is rotationally constrained relative to first housing 316, first cup 312 moves axially along longitudinal axis 302 of dual-end container 300. In this example, vial 340 does not move axially along longitudinal axis 302 of dual-end container 300. Conversely, the vial 340 remains stationary in the dual-end container 300 and the consumer may remove the second cap 322 disposed over the vial 340 to access the product contained within the vial 340.
Fig. 4 is a front view of a dual end container 400 according to yet another example. The dual-ended container 400 is similar to the dual-ended container 100 except that the second cup is configured to hold an applicator 450. Examples of the applicator 450 include a sponge, brush, spatula, flocked tip, non-flocked tip, and the like.
While the above-described examples contemplate the first and second threaded members 230, 232 being disposed on the drive member 110, in yet another example, the first and second threaded members 230, 232 may be disposed in the first and second housings 116, 118, respectively. Providing the first threaded member 230 in the first housing 116 and the second threaded member 232 in the second housing 118 may result in a more integrated mechanism, which may further shorten the length of the dual-end container 100.
Fig. 5 is a perspective view of another example of a first cup 512 and a second cup 514 that may be used in the dual end container 100 according to yet another example. First cup 512 has an interior volume 564 and an outer surface 560, the outer surface 560 having a first male thread 517 formed thereon. The second cup 514 has an interior volume 566 and an exterior surface 562, the exterior surface 562 having a second male thread 523 formed thereon. In one example, the first male threads 517 and the second male threads 523 are staggered. The diameter of the outer surface 560 of the first cup 512 is equal to the diameter of the outer surface 562 of the second cup 514. The interior volume 564 of the first cup 512 and the interior volume 566 of the second cup 514 may also be equal.
In operation, the first male threads 517 of the first cup 512 interact with a first threaded member of the drive member 110 (not shown), the drive member 110 being modifiable to operate according to the configuration of the first cup 512 and the second cup 514, and the second male threads 523 interact with a second threaded member of the drive member 110. When first housing 116 (which is modified to accommodate the configuration of first cup 512) is rotated relative to drive member 110 and first cup 512 is rotationally constrained relative to first housing 116, first cup 512 moves axially along longitudinal axis 102 of dual-ended container 100. Optionally, when the drive member 110 rotates relative to the first housing 116 and the first cup 512 is rotationally constrained relative to the first housing 116, the first cup 512 moves axially along the longitudinal axis 102 of the dual end container 100. More specifically, rotating the first housing 116 or the drive member 110 causes the first male threads 517 to engage with the first threaded member 230. In one example, the first threaded member 230 may be a first female thread. Rotation of the first housing 116 or the drive member 110 in a first direction causes the first cup 512 and the first product 124 to extend longitudinally out of the dual-end container 100, while rotation of the first housing 116 or the drive member 110 in a second direction causes the first cup 512 and the first product 124 to retract longitudinally into the dual-end container 100.
Similarly, when the second housing 118 (which is modified to accommodate the configuration of the second cup 514) is rotated relative to the drive member 110 and the second cup 514 is rotationally constrained relative to the second housing 118, the second cup 514 moves axially along the longitudinal axis 102 of the dual end container 100. Optionally, when the drive member 110 rotates relative to the second housing 118 and the second cup 514 is rotationally constrained relative to the second housing 118, the second cup 514 moves axially along the longitudinal axis 102 of the dual end container 100. Rotation of the second housing 118 or the drive member 110 causes the second male threads 523 to engage the second threaded member 232, which second threaded member 232 may be modified to accommodate the configuration of the second cup 514. Rotation of the second housing 118 or the drive member 110 in a first direction causes the second cup 514 and the second product 126 to extend longitudinally out of the dual-end container 100, while rotation of the second housing 118 or the drive member 110 in a second direction causes the second cup 514 and the second product 126 to retract longitudinally into the dual-end container 100.
An advantage of the present disclosure is that the overall length of the dual end cosmetic container is reduced due to the use of an integrated mechanism in which the second cup is partially housed within the first cup. In other words, the present disclosure uses the space required for a single extension and retraction mechanism by having the second extension and retraction mechanism fit therein. These integrated mechanisms allow two cosmetic products to extend and retract from opposite ends of the container independently of one another. Another advantage of the present disclosure is that the mechanisms described herein are designed to prevent accidental actuation of the cosmetic product. More specifically, the only housing, and thus the product, that will be actuated and extend and retract along the length of the container is the product desired by the consumer.
Fig. 6 is a schematic cross-sectional view of a dual end container 600 according to another example. Fig. 7 is an exploded cross-sectional view of the dual end container 600 of fig. 6. The dual-end container 600 is similar to the dual-end container 100. However, the dual end container 600 includes a first drive member 607 and a second drive member 608, which when coupled together form a drive member assembly 611. In addition to the advantages described above, the use of separate and distinct first and second drive members 607 and 608 allows each end of the dual end container 600 to be individually filled with product to reduce production time and to protect the filled product during subsequent assembly.
The dual-ended container 600 includes a first subassembly 671 and a second subassembly 673. The first subassembly includes a first cup 612 surrounded by a first housing 616 and a first drive member 607. The first cap 620 is coupled with the first housing 616. The second subassembly 673 includes a second cup 614 surrounded by a second housing 618 and a second drive member 608. The second cap 622 is coupled to the second housing 618. As shown in fig. 6-7, the second housing 618 includes a first recessed channel 631 configured to receive a portion 669 of the second drive member 608. Additionally, the second drive member 608 is configured to encircle a portion of the second cup 614 and thus stabilize the second cup 614 within the second drive member 608 and the second housing 618 when the dual-ended container 600 is in the two subassemblies (the first subassembly 671 and the second subassembly 673).
When the first subassembly 671 and the second subassembly 673 are coupled together, as described in more detail below, the first drive member 607 and the second drive member 608 are located between the first cup 612 and the second cup 614 along the longitudinal axis 602. Each of the first drive member 607, the second drive member 608, the first cup 612, the second cup 614, the first housing 616, the second housing 618, the first cap 620, and the second cap 622 may be made of plastic or any other suitable material.
The first cup 612 is configured to hold a first product 624. For example, the first cup 612 generally includes a product container portion 630 for holding the first product 624. The second cup 614 is configured to hold a second product 626. Likewise, the second cup 614 generally includes a product container portion 632 for holding a second product 626. In one example, the first product 624 and the second product 626 include cosmetic products such as lipsticks, lip gloss, foundations, mascaras, eyeliners, eye shadows, or blushers. In another example, one or both of the first product 624 and the second product 626 may be replaced with a cosmetic applicator, such as a sponge or brush. In yet another example, the first product 624 and the second product 626 are personal care products, such as deodorants. In still further examples, one or both of the first product 624 and the second product 626 are skin care products. In even further examples, the first product 624 and the second product 626 can be hair care products or pet products.
The dual-ended container 600 includes a threaded region 639 that moves one or both of the first cup 612 and the second cup 614 along the longitudinal axis 602 when relative rotational movement is provided between the drive member assembly 611 and either the first cup 612 or the second cup 614. The first cup 612 is adapted to move along the longitudinal axis 602 in an enlarged interior region 625 of the first housing 616. Likewise, second cup 614 is adapted to move along longitudinal axis 602 in enlarged interior region 627 of second housing 618.
As shown in fig. 7, the first drive member 607 is a hollow body surrounding the interior volume 654 and has a slot portion 656, such as a T-slot, groove, or other cutout, toward the first end 657. The second end 659 is opposite the first end 657. Further, the first driving member 607 has a first screw member 651, the first screw member 651 being a female screw member. The second drive member 608 has an interior volume 667, the interior volume 667 having a second threaded member 661 near the first end 658, the second threaded member 661 being a female threaded member. The second drive member 608 also includes a coupling member 663 near the first end 658. The coupling member 663 is configured to couple the second drive member 608 to the second housing 618, for example, by snapping into the first recessed channel 631 or otherwise coupling with the first recessed channel 631. A portion 675 of the first cup 612 is received in the interior volume 654. A portion 677 of the second cup 614 is received in the interior volume 667. The first cup 612 has an interior volume 613 and an outer surface 615, the outer surface 615 having first male threads 617 formed thereon. The second cup 614 has an interior volume 619 and an exterior surface 621, the exterior surface 621 having a second male thread 623 formed thereon. The diameter of the outer surface 621 is smaller than the diameter of the interior volume 613 such that when the dual-end container 600 is finally assembled, the second cup 614 is at least partially received within the interior volume 613 of the first cup 612. The first threaded member 651 of the first drive member 607 engages the first male threads 617 of the first cup 612 and the second threaded member 661 of the second drive member 608 engages the second male threads 623 of the second cup 614.
As shown, the first male threads 617 are right-hand threads and the second male threads 623 are right-hand threads. In another example, which may be combined with one or more examples described herein, the first male threads 617 and the second male threads 623 are left-hand threads. In another example, which may be combined with one or more examples described herein, the first male threads 617 are right-hand threads and the second male threads 623 are left-hand threads. In yet another example, which may be combined with one or more examples described herein, the first male threads 617 are left-hand threads and the second male threads 623 are right-hand threads.
The first cap 620 is removable from the first housing 616 to expose the first product 624 for use. The first cap 620 generally serves to cover the first product 624 when the first product 624 is not in use. The second cap 622 is removable from the second housing 618 to expose the second product 626 for use. The second cap 622 generally serves to cover the second product 626 when the second product 626 is not in use. As shown in fig. 6-7, the first cap 620 has a flat top surface 620A and the second cap 622 has a flat top surface 622A. It is also contemplated that one or more of the top surfaces 620A, 622A are tapered. According to other alternative examples, the first cap 620 and the second cap 622 may have other desired shapes. The first cap 620 may be sized to removably snap fit to the first housing 616 or to interference fit with the first housing 616. The second cap 622 may be sized to loosely cover the second housing 618.
By providing relative rotational movement between the first housing 616 and the drive member assembly 611, the first cup 612 is movable along the longitudinal axis 602 of the dual-ended container 600. By providing relative rotational movement between the second housing 618 and the drive member assembly 611, the second cup 614 is movable along the longitudinal axis 602 of the dual-ended container 600.
The first drive member 607 is engaged with the first and second housings 616, 618. The first driving member 607 is rotatable relative to the first housing 616. The first drive member 607 is rotatable relative to the second housing 618. In operation, when first housing 616 is rotated relative to first drive member 607 and first cup 612 is rotationally constrained relative to first housing 616, first cup 612 moves axially along longitudinal axis 602 of dual-end container 600. Alternatively, when first drive member 607 is rotated relative to first housing 616 and first cup 612 is rotationally constrained relative to first housing 616, first cup 612 moves axially along longitudinal axis 602 of dual-end container 600. More specifically, rotating the first housing 616 or the first drive member 607 causes the first male threads 617 to engage the first threaded member 651. Rotating the first housing 616 or the first drive member 607 in a first direction (e.g., toward the left side of the page, as shown in fig. 6-7) advances the first cup 612 and the first product 624 axially away from the second cup 614 to expose the first product 624 for use, while rotating the first housing 616 or the first drive member 607 in a second direction (e.g., toward the right side of the page, as shown in fig. 6-7) retracts the first cup 612 and the first product 624 longitudinally toward the second cup 614 of the dual-end container 600 to allow the first cap 620 to enclose and cover the first product 624.
Similarly, when second housing 618 is rotated relative to first drive member 607 and second cup 614 is rotationally constrained relative to second housing 618, second cup 614 moves axially along longitudinal axis 602 of dual-end container 600. Alternatively, when first drive member 607 is rotated relative to second housing 618 and second cup 614 is rotationally constrained relative to second housing 618, second cup 614 moves axially along longitudinal axis 602 of dual-end container 600. Rotation of the second housing 618 or the first drive member 607 causes the second male threads 623 to engage the second threaded member 661. Rotating the second housing 618 or the first drive member 607 in a first direction, e.g., clockwise (toward the left side of the page, as shown in fig. 6-7), advances the second cup 614 and the second product 626 axially away from the first cup 612 to expose the second product 626 for use, while rotating the second housing 618 or the first drive member 607 in a second direction, e.g., counterclockwise (toward the right side of the page, as shown in fig. 6-7), retracts the second cup 614 and the second product 626 longitudinally toward the first cup 612 to allow the second cap 622 to enclose and cover the second product 626.
As described above, once finally assembled, the dual end container 600 is similar to the dual end container 100 disclosed herein. Similar to the dual-end container 100, the dual-end container 600 may also include various stop mechanisms and shoulders to prevent over-extension of the product and disassembly of the various components of the dual-end container 600. For example, the first housing 616 may include a stop mechanism, such as the first stop 128 shown in fig. 1A-2B, that interacts with a shoulder, such as the shoulder 134 shown in fig. 1A-2B that extends radially outward from the product container portion 630. As the first cup 612 moves away from the first drive member 607 along the longitudinal axis 602, the shoulder contacts the first stop to prevent additional movement of the first cup 612 along the longitudinal axis 602.
Likewise, the second housing 618 may include a stop mechanism, such as the second stop 129 shown in FIGS. 1A-2B, that interacts with a shoulder, such as the shoulder 136 shown in FIGS. 1A-2B that extends radially outward from the product container portion 132. As the second cup 614 moves away from the first drive member 607 along the longitudinal axis 602, the shoulder contacts the second stop to prevent additional movement of the second cup 614 along the longitudinal axis 602. Additionally, the slot portion 656 attenuates the reaction force of the first threaded member 651. In other words, the slot portion 656 prevents the first cup 612 from forcing the first housing 616 and the first drive member 607 apart.
As discussed above, the first subassembly 671 and the second subassembly 673 of the two-terminal container 600 are configured to be joined together. The first subassembly 671 and the second subassembly 673 can be joined by any suitable joining technique. Suitable bonding techniques include, but are not limited to, snap-fit, press-fit, adhesive, welding, threaded engagement, and right angle rotation (quarter turned) fastening. As shown in fig. 6-7, the first drive member 607 and the second drive member 608 are configured to be coupled together to form a drive member assembly 611. For example, the second drive member 608 includes a recessed portion 665 configured to receive a portion of the first cup 612.
Thus, the product container portions 630 and 632 of the first and second cups 612 and 614 may each be filled individually, while the dual-ended container 600 is divided into a first subassembly 671 and a second subassembly 673. The first subassembly 671 and the second subassembly 673 may then be joined together. A method of assembling a dual end container in accordance with examples disclosed herein generally includes forming a first dual end container portion including a first cup coupled to a first housing and a first drive member, forming a second dual end container portion including a second cup coupled to a second housing and a second drive member, filling the first cup with a first product, filling the second cup with a second product, and then coupling the first dual end container portion to the second dual end container portion after filling. Generally, the filled product is moved downwardly and a cap is placed over the filled product in each of the first two-end container portions, which are then bonded together to protect the filled product. The mold may be used to fill and form a product in a desired shape for a dual end container. For example, when the product is a cosmetic product such as lipstick or foundation, the mold is generally used to shape the product into a bullet shape.
Filling the first and second cups 612, 614 separately reduces production time and provides protection of the product during filling and assembly.
While the foregoing is directed to the examples of the present disclosure, other and further examples of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
