Abstract
The shape-producing toothpaste dispenser includes a shape template with a length and a plurality of apertures formed within the length and a template-holding toothpaste cap. The plurality of apertures are arranged in a linear configuration with at least two of the plurality of apertures having a shape different from one another and the cap is shaped to removably physically couple to a neck of a toothpaste tube. The cap has a mouth with inwardly-disposed wall elements forming a pair of inwardly-facing U-shaped channels adapted to slidably secure the shape template within. The cap also has an inner surface defining a toothpaste-guiding channel extending through the cap and defining a passageway for passing toothpaste from an interior of the tube through one of the plurality of apertures when the shape template is secured within the mouth.
Description
- The present invention relates generally to an extrusion shaper for a pasty material, and more particularly relates to a multi-orifice shape-producing toothpaste cap assembly.
- It is indisputable that oral hygiene is key to the health and longevity of one's teeth. Regular brushing with toothpaste, which removes dental plaque and tartar from teeth, is the easiest way to prevent cavities, gingivitis, and gum disease. Research has shown that oral hygiene, by removing bacteria from the mouth, is not only beneficial to the teeth, but is also important to one's overall health.
- Although adults realize the benefits of oral health, many children do not embrace the process or the need to perform multiple brushings per day. Over the years, several devices have been introduced to the consumer market with the goal of encouraging children to brush well and more often. Examples of these devices include toothbrushes shaped like characters, toothbrushes that play music, toothbrushes with varying sizes of handles, toothpaste with sparkles and mixed colors, and many others.
- One device that provides an alternative to the traditional round tubular shape given to toothpaste as it is extruded from its storage tube is shown in
FIG. 1 . This prior-art device 100 has acap 104 that attaches to a tube oftoothpaste 103. Thedevice 100 has a rotatingdisc 102 provided with multiple apertures 106 a-d, each one having a unique shape. A user is able to rotate thedisc 102 to the selected aperture 106 a-d and, when thetoothpaste tube 103 is squeezed, the toothpaste is extruded through the selected aperture, which gives the toothpaste flow the shape of the selected aperture 106 a-d. However, thedevice 100 is not removable/replaceable and, therefore, the device is limited to only those few shapes 106 a-d (4 shown inFIG. 1 ) provided on thesingle disc 102. Also, as the disk is rotated, toothpaste is smeared along the underside and trapped between thedisk 102 and thecap 104. There is no simple way to clean the toothpaste, which will eventually harden and cause the disc to be difficult to rotate and present contamination issues. - Therefore, a need exists to overcome the problems with the prior art as discussed above.
- Briefly, in accordance with the present invention, disclosed is a shape-producing toothpaste dispenser that includes a shape template with a length and a plurality of apertures formed within the length and a template-holding toothpaste cap. The plurality of apertures are arranged in a linear configuration with at least two of the plurality of apertures having a shape different from one another and the cap is shaped to removably physically couple to a neck of a toothpaste tube. The cap has a mouth with inwardly-disposed wall elements forming a pair of inwardly-facing U-shaped channels adapted to slidably secure the shape template within. The cap also has an inner surface defining a toothpaste-guiding channel extending through the cap and defining a passageway for passing toothpaste from an interior of the tube through one of the plurality of apertures when the shape template is secured within the mouth.
- In accordance with another feature, an embodiment of the present invention includes a circular inwardly-facing portion adapted to engage the neck of the tube.
- In accordance with a further feature of the present invention, the cap includes threads disposed on the inner surface, the threads being adapted to mate with a standard toothpaste tube.
- In accordance with yet another feature of the present invention, a line of weakness is disposed along the length, the line of weakness allowing the shape template to bend at an approximately 90-degree angle without breaking.
- In accordance with an additional feature of the present invention, a tab is disposed at an end of the shape template, the tab being operable to limit an amount of slidable movement of the shape template within the U-shaped channels.
- In accordance with a further feature, the present invention includes an area along the length of the shape template free of apertures and proximal to the tab, the area disposed to seal an interior of the toothpaste tube from the environment when aligned with the passageway.
- In accordance with another feature, an embodiment of the present invention also includes a method of extruding toothpaste from a tube, where the method includes physically coupling an extrusion cap to a neck of a toothpaste tube, the extrusion cap shaped to removably mate with the tube of toothpaste and has a circular inwardly-facing inner surface and a mouth having inwardly disposed wall elements forming a pair of inwardly facing U-shaped channels. The method further includes sliding a shape template within the U-shaped channels to align an aperture formed within the shape template with an inner diameter of the neck, the shape template having a proximal extent, a distal extent, a length connecting the proximal extent to the distal extent, and a plurality of apertures formed within the length between the proximal extent and the distal extent, the aperture having a shape different from at least one other of the plurality of apertures.
- In accordance with yet another feature of the present invention, the method includes applying pressure to the tube of toothpaste whereby toothpaste within the tube of toothpaste is extruded through the aligned aperture.
- The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views and which, together with the detailed description below, are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.

cap portion 204 is provided with a shapetemplate holding portion 212 that slidably engages theshape template 206 and secures it in one of a plurality of positions so that one of the plurality of apertures 210 a-n is aligned with the outlet of thetoothpaste tube 202, i.e., the inner diameter of the neck of thetoothpaste tube 202. - In one embodiment of the present invention, as shown in
FIG. 3 , the shapetemplate holding portion 212 includes a pair of opposing inwardly-facing U-shapedchannels 302 a, 302 b that engage the edges of theshape template 206 and are adapted to slidably engage and secure theshape template 206 in one of a plurality of locations along the length of the template. -
FIG. 3 also shows a neck-engagement portion 304 of thecap portion 204. The neck-engagement portion 304 removably couples to the neck of a standard toothpaste tube, such astube 202. In the embodiment shown inFIG. 3 , the neck-engagement portion 304 does not have threads. In this embodiment, theinner surface 306 of the neck-engagement portion 304 has a diameter that is sized to be slight less than the diameter of the external threads found on standards tubes of toothpaste. In this way, thecap portion 204 fits snuggly over the external threads located on a standard toothpaste tube neck and secures thecap portion 204 to thetube 202 until removal is desired. The interior surface can be formed of plastic, a softer, more pliable material, such as rubber, or any other material suitable for adhering thecap portion 204 to the neck of atoothpaste tube 202. - Referring now to
FIG. 4 , thecap portion 204 is shown in an elevational, partially hidden view. In this view, it can be seen that thecap portion 204 defines apassageway 402 through which toothpaste can pass from an interior 404 of thetoothpaste tube 202, through thepassageway 402, through one of multiple apertures 210 a-n of the shape template 206 (if thetemplate 206 is in place) and into the environment. Naturally, toothpaste of a consistency commonly found in the marketplace will assume the shape of any template through which it is pushed. For example, referring back toFIG. 2 , a flow of toothpaste 214 is shown exiting thetube 202. In this example, the flow of toothpaste 214 has been forced through the aperture 210 b and, as a result, has taken on theshape 216 of the aperture 210 b which, in this particular example, is a star. If, alternatively, theshape template 206 were slid one aperture position over, the toothpaste 214 would be extruded through theaperture 210 c and the toothpaste 214 would be given the shape of a heart, which is the exemplary shape ofaperture 210 c. - In the particular embodiment shown, at one extent of the
passageway 402 is a raisedring 406. The raisedring 406, when present on thecap portion 204, provides a seal against an inner surface of theshape template 206 that faces thetoothpaste tube 202 when theshape template 206 is within the shapetemplate holding portion 212. Theseal 406 helps prevent toothpaste from flowing between the junction of thecap portion 204 and the inner surface of theshape template 206 when the toothpaste is being forced throughpassageway 402. In one embodiment, the inner surface of theshape template 206 is provided with an indentation having a shape that mates with a shape ofring 406. When theshape template 206 is moved to align one of the apertures 210 a-n with the neck of thetoothpaste tube 202, an alignment between thering 406 and the indentation provides a tactile feedback to the user and indicates that thetemplate 206 is in a proper location. Thering 406 can be provided in any shape. In addition, thering 406 can be provided on the inner surface of theshape template 206 and the indentation can be provided on thecap portion 204. In other embodiments, alignment can be achieved by a combination of raised and indented areas on thecap portion 204 that correspond to a reverse combination of raised and indented areas on theshape template 206. -
FIG. 5 shows an elevational view of ashape template 500. In this embodiment, a blank 502 is provided at oneend 504 of theshape template 500, the blank 502 being in alignment with additional apertures 510 a-n. Also shown in this embodiment, theshape template 500 has a pair offlanges end 504. Theflanges shape template 500 can slide through thechannels 302 a, 302 b of the shapetemplate holding portion 212, as shown inFIG. 3 . In this embodiment, when theflanges channels 302 a, 302 b, the blank 502 will be aligned with the opening of thetoothpaste tube 202. In this way, the blank 502 will seal thetoothpaste tube 202, preventing drying of the toothpaste within theinterior 404 of thetube 202. As described above, one surface of the blank 502 can be provided with a raised area 508 (or an indented area or a combination of raised and indented areas) to provide improved sealing between theinventive cap 204 and thetoothpaste tube 202. - Also shown in
FIG. 5 is a line ofweakness 512 within theshape template 500. The line ofweakness 512 can include an area of reduced material, a compressed area, a hinged area, or any other arrangement that allows theshape template 500 to bend at an approximately 90-degree angle. In one embodiment, when theflanges channels 302 a, 302 b and the blank 502 is aligned with the opening of thetoothpaste tube 202, the line ofweakness 512 is just slightly outside the widest dimension of thetoothpaste tube 202. By positioning the line ofweakness 512 to be just slightly outside the widest dimension of thetoothpaste tube 202, when the blank 502 is located over the mouth to seal thetoothpaste tube 202, bending theshape template 206 reduces the overall footprint of the device from that shown inFIG. 1 to that shown inFIG. 5 and, advantageously, reduces the required storage space of the device. By bending theshape template 500 along the line ofweakness 512, theinventive dispenser assembly 200, when attached to atoothpaste tube 202, only minimally increases the size of the overall footprint of the toothpaste tube. - The present invention provides advantages over the previously-known devices due, at least in part, to the fact that
multiple shape templates 206 can be easily utilized with thesame cap portion 204. One simply needs to slide afirst shape template 206 out of thechannels 302 a, 302 b of the shapetemplate holding portion 212 and insert a new shape template, having shapes different from those formed in thefirst shape template 206. This unique feature allows the user to obtain a plurality of templates and a corresponding even greater plurality of unique shapes so that the user never gets bored of the same shape. -
FIG. 6 shows a process flow diagram illustrating one embodiment of the present invention. The process starts atstep 600 and moves directly to step 602 where a user physically couples theextrusion cap 204 to a neck of atoothpaste tube 202. Instep 604, the user slides theshape template 206 within the U-shaped channels 302 a-b to align one of the apertures 210 a-n formed within the shape template with an inner diameter of the neck of the toothpaste tube. Instep 606, the user applies pressure to the toothpaste tube, thereby causing toothpaste within the tube to be extruded through the toothpaste tube. Instep 608, the user slides the shape template within the U-shaped channels until atab step 610. - It should be noted that the present invention is not necessarily limited to attachment to toothpaste tubes. In alternative embodiments, the
mouth 304 of thecap 200 is sized to attach to other material dispensers, such as a CHEEZE WIZ can, peanut butter tubes, cake icing dispensers, and more. - A toothpaste shaper has been disclosed that features positionable and replaceable shape templates that are easily and quickly slidably positioned from one shaped aperture to another. The invention provides shaped orifices that are easy to use, requiring less dexterity than prior-art devices. In addition, the present invention provides shaped orifices that are always visible, which makes the device easily used and understood by persons of all ages. Other features of the invention have also been disclosed that add further versatility to the apparatus but are not necessary and are not intended to be limited to the particular details disclosed herein.
