(15) The outer container 102 is a reusable container or bottle. This outer container 102 is structurally designed to encompass an inner container and allow for dispensing toothpaste.

(16) The outer container 102 is disposed of a collapsible or bendable material, such as a soft-weight plastic. For example, the outer container can be composed of soft plastics, such as a thermoplastic elastomer. In another example, the outer container can be composed of different materials or multiple plastics having varying elasticity. For example, in one embodiment the outer container can include a hard plastic or metal outer edge, with softer plastic interior or middle section for dispensing paste.

(17) Not visible in FIG. 1, an inner container is disposed within outer container, secured in place by connection to the cap 104. External compression on the outer container 102 translates to compression on the inner container, allowing for dispensing via the cap 104.

(18) The cap 104 attaches to the outer container 102 using a compression or snap-fit mechanism, as described in greater detail below. The cap 104 closes the interior portion, securing the inner container therein.

(19) In one embodiment, the outer container 102 can include a window 106. The window 106 can be fully see-through or at least partially see-through, allowing visibility to the inner container stored therein. Visibility allows the user to determine the amount of toothpaste remaining in the inner container. The window 106 can be made of the same plastic or deformable material, such as using varying coloring or composite material. The window 106 can also be made of a different material or the same material with a varying degree of hardness or deformability.

(20) Further visible in FIG. 1 are cap locking elements 108. As described in greater detail below, the cap locking elements 108 provide for securing the cap 104 to the outer container 102 and allowing for disengaging the cap 104 therefrom.

(21) FIG. 2 illustrates a side view of the dispensing device 100, showing the side view of the outer container 102 and the cap 104. Similar to FIG. 1, the cap 104 is affixed to the outer container 102. In this embodiment, the cap 104 includes a flat front face, allowing for resting the dispensing in the device in an upright position.

(22) In this embodiment, the window 106 of FIG. 1 is flush within the front face surface of the outer container, therefore not expressly illustrated in FIG. 2 as not be directly visible from the side view. The cap locking element 108 is additionally visible, illustrated in this embodiment as a depressible button. Once the button is depressed, the internal features of the locking element (not visible in FIG. 2) releases pressure engagement against the cap 104.

(23) FIG. 3 illustrates a perspective view of the dispensing device 100, providing further illustration of the outer container 102, the cap 104, the window 106, and the cap locking element 108. As visible in this embodiment, the outer container 102 has an elongated shape with a curved top.

(30) The inner container 120 is made of a material not intended for direct consumer handling or directly squeezed by the consumer on a daily basis. Rather, the inner container 120 is designed to be placed within the outer container (102 of FIG. 1). For example, the inner container 120 includes an internal pouch storing the toothpaste with a fused outer ridge providing rigidity.

(31) The inner container 120 has minimal material usage in its construction. The inner container 120 can have a smaller material-mass to toothpaste-mass ratio compared with traditional toothpaste tubes. The placement of the inner container 120 within the outer container (102 of FIG. 1) allows for thinner or minimal material usage to ensure the container integrity for holding and dispensing liquid or paste.

(32) In one embodiment, the inner container 120 may include a nozzle 122 affixed at a bottom end. The nozzle 122 operates consistent with known nozzle technology, allowing for the toothpaste within the inner container 120 to pass through upon force activation upon the inner container 120. The nozzle 122 includes an aperture for allowing the paste to travel therethrough.

(33) The nozzle 122 further includes a nozzle locking element 124 disposed on the exterior of the nozzle 122. In one embodiment, the nozzle locking element 124 is a grooved element for mating with the cap, as described in greater detail below. The locking element 124 can be a grove allowing to screw or snap-fit the nozzle into the cap. Moreover, the locking element 124 can be any suitable mechanical means to affix and secure the cap to the nozzle 122.

(34) FIG. 6 illustrates a side view of the inner container 120, illustrating the thickness of this embodiment. Moreover, the pouch shape with the rigid edges provides for improved dispensing of paste and maintaining structural integrity once installed. Also visible are the nozzle 122 and the nozzle locking elements 124.

(35) FIG. 7 illustrates another perspective view of the inner container 120 with the nozzle 122 and the nozzle locking element 124. Visible in FIG. 7, the nozzle locking element 124 includes the raised groves with a stop cap for controlling not only the depth of the nozzle 122 within the aperture of the cap, but also to control the amount of insertion force or twisting required.

(36) Also visible in FIG. 7, the nozzle 122 is a pathway allowing for toothpaste to pass therethrough.

(37) In a further embodiment, the inner container 120 can be shipped to the consumer with a protective seal covering the nozzle 122, such as being affixed with a small amount of adhesive material. The seal ensures the integrity and freshness of the paste inside the inner container 120 during transport to the consumer and prior to installation within the outer container.

(38) The user can manually remove the seal either just before or after installation of the inner container. Whereas, as noted in further detail below, once installed, the paste is kept fresh based on the cap, such as a lid or a closure valve.

(39) FIGS. 8 and 9 illustrate varying perspective views of the cap 104. Visible in FIG. 8, the cap 104 includes the bottom of the aperture 110 and the closure valve 112. Visible in FIGS. 8 and 9, but described in greater detail with respect to FIG. 10, the cap 104, in this embodiment, is composed of three different segments.

(40) FIG. 9 illustrates the top view of the cap 104. Visible are mating grooves 130 within the aperture 110 and cap locking tabs 132 on the interior of the cap.

(41) FIG. 10 illustrates an exploded view of the assembly of the cap 104 and the outer container 102. The outer container 102 includes the window 106 and the cap locking elements 108.

(42) The cap locking elements 108 further include the cap locking tabs 132 as part of the cap 104. In this embodiment, the cap 104 is composed of three primary segments, a first segment 140 having the cap locking tabs 132, a second segment 142 with the aperture 110, and a third segment 144 as the bottom portion.

(43) The cap 104 and the segments 140, 142, and 144 can be made of molded plastic, similar material, or any other suitable material. The segments 140, 142, and 144 can be affixed together to form the cap 104. For example, in varying embodiments, the segments can be glued together or can be snap-fitted.

(44) Also visible in the exploded view, the closure valve 112 sits at the bottom of the aperture 110.

(45) FIG. 10 further illustrates a further embodiment with a base 150. The base 150 can be made of any suitable material, having a recess or groove 152 providing for the cap 104 to sit therein.

(46) The base 150 may further include a supplemental base element 154 holding a timer element 156 therein. The timer 156, in this embodiment, may be a manually-operated hour-glass shaped timer. The timer 156 can include sand or other material designating the recommended time for brushing one's teeth. The user can, in this embodiment, manually flip the timer for controlling the tooth brushing duration.

(47) Further embodiments may include additional components associated with the dispensing device. For example, one embodiment may include a base tray for holding the dispensing device. The base tray can include electronics, such as detecting the number of times the dispensing device is activated or a timer providing a countdown until a next delivery is requested or required.

(48) A further embodiment can include a timer, whether it be an electrical or mechanical timer. For instance, the timer can provide a timed countdown for how long the user should be engaged in brushing his or her teeth, such as the two minutes per brushing session recommended by the American Dental Association.

(49) The timer can be a stand-alone device, such as found in the base, or can be associated with the dispensing device. For example, a sensor can detect when the outer container is removed from a base station, this can begin the timer. In another example, a timer can be fitted in the outer container, beginning timing either upon detecting toothpaste dispensing or movement by the user.

(50) The dispensing device provides for replacement inner containers. Therefore, the device allows for assembly and re-assembly. FIG. 11 illustrates assembling or securing the inner container 120 within the cap 104. The nozzle 122 extends into the aperture 110.

(51) FIG. 12 illustrates the inner container 120 is affixed within the aperture by, in this embodiment, rotating the inner container 120 to screw the nozzle and the nozzle locking element 124 in place. Thereby, the inner container 120 is secured to the cap. The rigidity of the inner container 120 allows the inner container 120 to remain upright.

(52) It is noted, for removing the inner container 120, for example once all toothpaste has been expelled, the twisting process is reversed. Thus, in this embodiment, the inner container 120 can be removed by unscrewing from the cap 104.

(53) FIG. 13 illustrates the further assembly process, whereby the outer container 102 slides over the inner container 120. As the outer container 102 slides down, the cap 104 secures to the outer container 102 via the cap locking mechanisms 108. In this embodiment being snap-fit connections.

(54) Similar to FIG. 12, the removal and replacement of the inner container follows the reverse operation. Compression of the cap locking mechanism 108 removes the snap-fit or compression engagement with the mating grooves 130 of the cap 104. The cap 104 can then be slid apart from the outer container 102.

(55) In the embodiment where the closure valve is secured within the cap 104, installation of the inner container 120 can include removal of a protective seal on the nozzle.

(56) Further embodiments can provide for varying designs and shapes for the outer container 102, the inner container 120 and the cap 104. For example, a decorative cap can include a decorative finish, such as a polished metal, providing improved visual aesthetics. The cap can include a logo or other writing.

(57) During normal operations, a user can receive monthly or periodic shipments of inner containers. The inner container includes toothpaste or other type of paste. The outer container is a re-usable container, the inner container being a one-time use, disposable container

(58) It is recognized that the outer container may utilize any suitable shape. The shape can be determined by material waste features, design features, ease of use, or any other factors. The inner container generally mirrors the outer container design, but it not expressly required. For instance, the outer container may have a unique shaped design and the inner container has a smaller material footprint in a tube-based shape accommodated within an interior portion of the outer container.

(59) Further design embodiments of the outer container may include external force application means for compressing the inner container. Where noted above human compression deforming the outer container causes paste extraction, other compression techniques can be utilized. For instance, a mechanical means applying a preset amount of pressure can be used, such as depressing a button that translated the button pressing into a specific force generation. Other techniques can include battery or electrically powered regulated compression forces upon the inner container.

(60) Further embodiments may utilize external monitoring and toothpaste extraction techniques. For example, the outer container may include mechanical or electrical triggers for compressing the inner container. Triggers can include buttons, voice activation, movement activation, or any other suitable technique.

(61) Further embodiments may include multiple inner containers or a single inner container having multiple channels. For example, one embodiment may include a combination of liquid and solid dispensing elements. In one example, a toothpaste can be dispensed from one channel, mixed with other paste or with a powder or liquid. The present dispensing device is not expressly limited to a single inner container usable with the outer container.
