Patent Application
20140059751
Embodiments herein relate to apparatuses and methods for applying a cleaning substance to a bathroom surface.
Cleaning/deodorizing compositions for use in toilets are available in several forms. Sprays and liquids are typically applied directly to an interior surface of the toilet bowl to aid mechanical cleaning (i.e., with a toilet brush or sponge). However, these cleaners require the use of a toilet brush or other means for mechanically removing surface debris.
Solid and semi-solid formulations are also available for use in toilets. Some pucks may be dropped into the tank portion of the toilet to release bleach, cleaners, disinfectants, and/or fragrances into the water each time the toilet bowl is refilled after flushing. Others may be suspended within the toilet bowl, such as below the upper rim of the bowl. In order to use these products, however, a user must remove the lid of the tank or mechanically attach and subsequently remove a hook or other suspension means from inside the toilet bowl In addition, the amount of cleaner or deodorizer released may vary dramatically throughout the useful life of the product.
More recently, semi-solid cleaners such as gels have become available for use in toilet bowls. A multi-use dispenser is pre-filled with adhesive gel. The dispenser forms the adhesive gel into discs, which are then stamped onto an interior surface of a toilet bowl. Each adhesive gel disc adheres to the surface and gradually dissolves over a predetermined period or time or number of flushes, at which time the dispenser is used again to stamp a new adhesive gel disc onto the interior surface of the toilet bowl. The dispenser typically requires assembly by the user. Incorrect assembly or use may cause the adhesive gel to be dispensed in greater than desired volumes. Further, the user must re-cap the end of the dispenser that has contacted the inside of the toilet bowl and store the dispenser for future use of the remaining adhesive gel. Such re-use of the soiled dispenser compromises sanitation and increases the risk of spreading and/or transmitting bacteria and/or toilet waste.
Embodiments provide an apparatus for applying a cleaning substance to a toilet bowl, the apparatus comprising a body having a wall defining a distally-facing cavity for releasably retaining the cleaning substance, the body further having a proximally-extending mechanism configured to facilitate gripping the apparatus and applying the cleaning substance to the toilet bowl when the cleaning substance is pressed against the toilet bowl.
Another embodiment provides an apparatus for applying a cleaning substance to a bathroom surface to be cleaned. The apparatus includes a body having a distally-facing wall defining a cavity for releasably retaining a cleaning substance, the body further having a proximally-extending releasing mechanism configured to selectively deform the wall, and thereby deform the cavity to release the cleaning substance from the cavity when the cleaning substance is pressed against the surface
Another embodiment provides a method for applying a cleaning substance to a toilet bowl. The method includes the following steps: selecting a wall defining a distally-facing cavity that releasably returns the cleaning substance, the wall having a distally-disposed terminal edge and a proximally-extending releasing mechanism; pressing the cleaning substance against the toilet bowl and manipulating the wall via the releasing mechanism to distort the wall and the cavity to release the cleaning substance from the cavity and apply the substance to the toilet bowl; and withdrawing the wall from the toilet bowl via the releasing mechanism.
Subject matter is particularly pointed out and distinctly claimed in the concluding portion of the specification. The foregoing and other features of the present disclosure will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the disclosure and are, therefore, not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through use of the accompanying drawings, in which:
In the following detailed description, reference is made to the accompanying drawings which form a part hereof and in which are shown by way of illustration embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of embodiments is defined by the appended claims and their equivalents.
Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments; however, the order of description should not be construed to imply that these operations are order dependent.
The description may use perspective-based descriptions such as up/down, back/front and top/bottom. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of disclosed embodiments.
The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements are not to direct contact with each other, but yet still cooperate or interact with each other.
Reference is made to the drawings wherein like numerals refer to like parts throughout. For ease of description, the components of embodiments of the present disclosure are described in the normal (upright) operating position, and terms such as upper, lower, horizontal, etc., are used with reference to this position. It will be understood, however, that the components of embodiments of the present disclosure may be manufactured, stored, transported, used, and sold in an orientation other than the position described.
Figures illustrating the components of embodiments of the present disclosure show some conventional mechanical elements that may be known and that may be recognised by one skilled in the art. The detailed descriptions of such elements are not necessary to an understanding of the disclosure, and accordingly are herein presented only to the degree necessary to facilitate an understanding of the novel features of the present disclosure.
As used herein and in the appended claims, the term “comprising” is inclusive or open-ended and does not exclude additional unrecited elements, compositional components, or method steps. Accordingly, the term “comprising” encompasses the more restrictive terms “consisting essentially of” and “consisting of.”
It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the content clearly dictates otherwise. Similarly, the use of substantially any plural terms herein may be translated by those having skill in the art from the plural to the singular as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
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., “an apparatus having at least one of A, B, and C” would include, but not be limited to, apparatuses 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.”
The description may use the terms “embodiment” or “embodiments,” which may each refer to one or more of the same or different embodiments. Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments, are synonymous.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the present invention pertain. Although a number of methods and materials similar or equivalent to those described herein can be used in the practice of the present invention, the preferred materials and methods are described herein.
The term “cleaning substance” as used herein refers to any cleansing, deodorizing, disinfecting, and/or fragrancing substance configured to adhere to a non-horizontal surface (e.g., a porous or non-porous surface comprising a plastic/polymer, ceramic, metal, glass, or stone surface) and remain substantially in place, without the aid of a separate supporting structure or mechanism, until at least partially dissolved, dissipated, or otherwise removed (e.g., by disintegration, sublimation, or mechanical force). Cleaning substances may be composed of one or more cleaning agents (e.g., surfactants, detergents), alkalis, oxidizers, petrochemicals/oleochemicals, emulsifiers, thickeners, enzymes, antimicrobials, fragrances, dyes, preservatives, fillers, and/or stabilizers. In addition, cleaning substances may take on any solid or semi-solid form such as but not limited to gels, pastes, waxes, and other solids or semi-solids.
Cleaning substances as contemplated in the present invention may be formed, and/or filled after blending operations, by one or more known manufacturing methods, such as melting and casting, extrusion, and/or compression, alone or in any combination. For example, a cleaning substance may be cast or compressed within, or extruded into, the cavity of an applicator in accordance with the claimed invention during the manufacturing process. Alternatively, the cleaning substance may be extruded in a log or other shape into the cavity of the applicator and severed at or near the edge of the cavity opening with a cutting device. As another alternative, the cleaning substance may be formed as a solid insert in a separate process and subsequently inserted into the cavity of the applicator (e.g., during the manufacturing process or by the end user prior to use). Accordingly, the cleaning substance and applicator may be supplied as separate components. While crescent or dome-shaped cleaning substances are described herein by way of example because such smooth, symmetrical shapes encourage even dissolution or dissipation of the cleaning substance, any variety of shapes may be used, such as but not limited to stars, flowers, fruits, rings, paw prints, and geometric designs.
The applicators as described herein may be constructed from one or more polymers such as polyethylene and/or polypropylene and manufactured by any suitable method known in the art for shaping plastics. Examples include, but are not limited to, injection molding, blow molding, thermoforming extrusion, casting, and compression/transfer molding.
Surfaces to which substances described herein may be applied include, but are not limited to, surfaces generally found in bathrooms, such as toilet bowls, sinks, bathtubs, bathtub walls, shower walls, and the like.

In the first embodiment of the claimed invention, as shown in
As shown in
In operation, as depicted in
Apparatus 10 may additionally include one or a combination of gripping features to improve a user's grip on the apparatus. These features may provide the additional benefit of supplying visual cues to a user, allowing him or her to intuit proper operation of the apparatus without the use of instructional manuals or written directions. In
Referring to
As shown in
In operation, like in previous embodiments, cavity 360 retains a cleaning substance prior to application to a bathroom surface to be cleaned. A user, holding member 380, extends the apparatus in the direction of a bathroom surface until contact is made and the cleaning substance adheres to the bathroom surface. Unlike in previous embodiments, however, after contact and adhesion is made, there may be no displacement of members 380 or distortion of wall 330 at a weakened portion. On the other hand, if the wall 330 is formed of flexible material the wall in fact may be distorted by pressing one distal side of the wall against the surface to be cleaned. The adhesive properties in the cleaning substance are typically sufficient to attach the cleaning substance to the bathroom surface after removal of the apparatus. When this occurs the cleaning substance is released from cavity 360, but remains applied to the bathroom surface.
As noted in previous embodiments, terminal edge 340 may make contact with the bathroom surface before, after, or simultaneously with the cleaning substance. In addition, apparatus 310 may include a releasing agent or material composed of, for example, a “hydrophobic” substance that is applied to at least a portion of a distally-facing wall of body 320 to aid the release of the cleaning substance from cavity 360.
Although cylindrical or dome-shaped applicators have been described herein by way of example, applicators may be formed in a variety of other shapes and/or include decorative patterns, designs, and/or other surface textures. For example, in the embodiment shown in
The depicted embodiments illustrate an apparatus that is supplied as a disposable single-use applicator that is pre-filled with a unit dose of a cleaning substance to be applied. Once the applicator has been used to dispense the cleaning substance onto the desired surface, the applicator may be discarded. In some examples (not shown here), the open end of the cavity proximate the terminal edge may be sealed with a removable feature that is pulled away from the applicator and discarded prior to application. Such removable features protect the cleaning substance during packaging and shipping and ensure optimal freshness and/or adhesion upon application. Examples of such removable features include, but are not limited to, induction seals, heat sealed films, injection molded covers, or trays that protect the cleaning substance contained in multiple applicators.
Although certain embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a wide variety of alternate and/or equivalent embodiments or implementations calculated to achieve the same purposes may be substituted for the embodiments shown and described without departing from the scope. Those with skill in the art will readily appreciate that embodiments may be implemented in a very wide variety of ways. This application is intended to cover any adaptations or variations of the embodiments discussed herein. Therefore, it is manifestly intended that embodiments be limited only by the claims and the equivalents thereof.
