A MIXING AND DISPENSING APPARATUS AND METHOD

Description

TECHNICAL FIELD

[0001] The present disclosure relates to a field of mixing devices. Particularly but not exclusively relates to a mixing and dispensing apparatus for use in dentistry and orthodontics. Embodiments of the disclosure disclose to an apparatus for mixing and dispensing of alginate compound for making dental impression material.

BACKGROUND

[0002] In general, dentists use a paste form, primarily an alginate paste to take a desired dental impression of a subject. Typically, the alginate paste may be obtained by mixing a liquid such as water with an alginate powder manually in adequate proportions. The mixed paste is transferred manually into a mould, after which the mould may be positioned around the teeth of the subject and allowed to solidify to obtain the desired dental impression. Obtaining a homogenous alginate paste by manual mixing is a time consuming and laborious task. Further, manual mixing requires skill and technique to obtain the alginate paste without any inconsistency and wastage.

[0003] With ongoing efforts, many apparatuses have been developed to mix the alginate powder and the liquid to obtain alginate paste having desired consistency. The conventional apparatuses comprise a mixing container, wherein adequate amount of the alginate powder and liquid may be added. The mixing container may be rotated to obtain the alginate paste. Further, the alginate paste is manually taken out from the container and transferred into the mould.

[0004] Though manual mixing is eliminated by the conventional apparatuses, the addition of material in the mixing container and dispensing of the paste still requires manual intervention. As the setting time for the alginate paste is very low, manual dispensing of the alginate paste may cause the alginate paste to set prior to its use. Further, precise amounts of the alginate powder and liquid must be selected for mixing to obtain the alginate paste, having a desired consistency. Furthermore, setting time of the alginate paste depends upon the quantity of alginate powder, quantity of liquid, mixing duration, temperature of the liquid and environmental conditions.

[0005] A conventional revolution-rotation stirrer as disclosed in JP2011045873 A (Norio et al.) comprises a rotating body firmly fixed to a revolution shaft pivoted on a substrate. The rotating body rotates in a horizontal surface. The stirrer further includes a container holder inserted and holds the stirring container that rotates centering around the rotational axis inclined in a rotation center direction of the rotating body at a position apart from the rotation center of the rotating body in a radial direction. The stirrer has a feeding-in opening for supply materials at a superior end on a second substrate parallel to the horizontal surface arranged at an upper position than the superior end of the container holder. Further, at the same time, a material supply pipe supplies the supply materials in a driving condition in the container holder axially-located and rotatably concentrically with the revolution shaft and in synchronism with the revolution shaft, by which a supply opening toward the container holder.

[0006] Therefore, a need exists for a mixing and dispensing apparatus to seek to mitigate one or more of the above disadvantages.

Equivalents:

[0077] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

[0078] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations.

[0079] In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B." While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting.
