DETAILED DESCRIPTION OF THE INVENTION
Many products exist to produce desired fragrances, to mask an undesired odor, or to release a desired chemical into the air, including deodorants, antiperspirants perfumes, air fresheners, insect repellents, etc. Deodorants and antiperspirants are often available as a stick of a semi-solid material disposed in a hand-held tube. Perfumes are typically sold as liquids or sprayable fluids in hand-held bottles. Many air fresheners and insect repellents are sold in a can and are applied as a spray.
While many of these products are useful, in many circumstances the size and form of existing odor- and fragrance-related products are inconvenient or impractical. For example, a typical deodorant or antiperspirant stick is too bulky to be carried in a pocket; consequently, many people do not do so and as a result are able to apply deodorant or antiperspirant only once before leaving home for the day (or night). If an occasion then arises in which a deodorant or antiperspirant may be needed, the person often does not have access to a deodorant or antiperspirant, and must do without. Similarly, a typical can of air freshener or insect repellent is bulky and awkward; most people would not consider carrying around a container of air freshener or insect repellent in a purse or coat pocket. In some circumstances, existing products cannot be carried for other reasons. For example, due to security concerns, a bottle of air freshener, or a bottle of perfume, may not be permitted on an airplane.
Accordingly, a need exists for smaller, more convenient, and more discrete fragrance- and odor-related products to facilitate easier carrying and use of such products.
FIGS. 1A-1C show a container in accordance with an embodiment. Container 100 is a packaging that holds a plurality of blocks each containing a material or chemical having a desired property such as a deodorant material, an antiperspirant material, a sanitizing material, a perfume, an insect repelling material, etc.
FIG. 1A shows a top view of block container 100 in accordance with an embodiment. Container 100 includes a plurality of sections 110 separated by perforated edges. In the illustrative embodiment, container 100 includes six container sections 110; however, in other embodiments, a container may contain any number of sections. The top surface of sections 110 is made of a suitable material 172, which may be paper, plastic, etc. Other materials may be used. Each individual section 110 may be detached from container 100 by tearing along its perforated edges 114. Each section 110 includes an enclosed volume 125. Each enclosed volume 125 is enclosed on the top side by a plastic material, which may be clear, translucent, or opaque. In other embodiments, enclosed volume 125 may be enclosed on the top side by another type of material, such as paper, foil, etc.
In one embodiment, enclosed volume 125 forms a circular or approximately circular shape less than 1.0 inch in diameter. In one embodiment, enclosed volume 125 forms a circular or approximately circular shape less than 0.5 inch in diameter. Enclosed volume 125 may have a different shape.
FIG. 1B shows a bottom view of container 100. The bottom surface of container 100 is covered by a layer 175 of aluminum foil. In other embodiments, layer 175 may include other materials. Each respective section 110 includes an outline 140 in the aluminum foil layer 175 that defines the bottom portion of the enclosed volume 125 of the respective section. Thus each enclosed volume 125 is sealed on the top side by a plastic material and on the bottom side by aluminum foil layer 175.
In one embodiment, outline 140 on bottom side of section 110 forms a circular or approximately circular shape less than 1.0 inch in diameter. In another embodiment, outline 140 on bottom side of section 110 forms a circular or approximately circular shape less than 0.5 inch in diameter. Other dimensions may be used. In other embodiments, outline 140 may have a different shape, such as a square or rectangular shape.
In a well-known manner, outline 140 is adapted to break as a result of pressure. For example, outline 140 may be a perforation that facilitates breakage of the aluminum foil layer.
A user may detach a single container section 110 in order to facilitate the removal of a block. FIG. 1C shows a top view of a single container section 110. In one embodiment, each side of section 110 is between 0.5 inches long and 2 inches long. In another embodiment, each side of section 110 is approximately 1.0 inch long. Other dimensions may be used.
Material 172 (e.g., paper, plastic, etc.) surrounds and defines enclosed volume 125, which is situated in a region that is centrally located on section 110. In the illustrated embodiment, a plastic material covers the centrally located region and is attached to material 172, defining enclosed volume 125. Thus, material 172 surrounds enclosed volume 125.
FIG. 1D shows a cross-section of the section of FIG. 1C taken along line A. A layer of material 172 (e.g., paper, plastic, etc.) forms a base for the structure of section 110 and surrounds enclosed volume 125. A plastic material 183 covers enclosed volume 125. Plastic material 183 may be a clear plastic, or may be translucent, opaque, etc. Aluminum foil layer 175 covers the bottom of material 172 and seals the bottom of enclosed volume 125. Other materials may be used for any of the layers described herein.
In the illustrative embodiment, layer 172 is adjacent to and attached to aluminum foil layer 175. For example, layer 172 may be glued to layer 175. Plastic material 183 is attached to material 172, for example, by glue. In another embodiment, plastic material 183 is attached to aluminum foil layer 175.
Thus, layer 172, plastic material 183, and aluminum foil layer 175 define enclosed volume 125. Specifically, plastic material 183 is separated from aluminum foil layer 183 by enclosed volume 125.
In accordance with the illustrative embodiment, enclosed volume 125 holds a block that includes a plurality of layers. A first layer 190 includes a semi-solid material. A second layer 195 includes an adhesive material. A pocket 128 containing air, or another gas, may be located in between semi-solid layer 190 and plastic material 183. In other embodiments, a vacuum may be present between semi-solid layer 190 and plastic material 183.
In one embodiment, the diameter of the block is less than 1.0 inch long. In another embodiment, the diameter of the block is less than 0.5 inches long. In another embodiment, a block has a square shape; each side is less than 1.0 inch long. In one embodiment, the height of the block is less than 1.0 inch. In another embodiment, the height of the block is less than 0.5 inch. Other dimensions may be used.
In one embodiment, semi-solid layer 190 may be made from a material similar to those commonly used in deodorant/antiperspirant sticks. Thus, semi-solid layer 190 may include a gelling agent that forms a semi-solid matrix. The gelling agent may include a waxy or fatty material such as stearyl alcohol, cetyl alcohol, hydrogenated castor oil, glyceryl stearate, etc. The waxy or fatty material may be blended with an oil and emollient such as cyclomethicone. Cyclomethicone is a volatile silicone compound, and is a liquid at room temperature but quickly evaporates. In addition, talc, starches, and/or powders may be added to control the consistency of semi-solid layer 190. A fragrance, one or more fragrance-producing chemicals, or one or more chemicals that mask a fragrance, may be added. The fragrance or chemical(s) may be in a time-released form.
In the illustrative embodiment, semi-solid layer 190 comprises a deodorizing material or chemical; therefore, the discussion herein treats layer 190 as a deodorizing material. However, in other embodiments, semi-solid layer 190 may include an antiperspirant material or chemical, a perfume-related substance or chemical, a sanitizing material or chemical, a sterilizing material or chemical, an air-freshening material or chemical, an insect-repelling material or chemical, etc.
Adhesive layer 195 may include any suitable type of adhesive substance. Thus, adhesive layer 195 may include a drying adhesive, a pressure-sensitive adhesive, a contact adhesive, or another type of adhesive. For example, adhesive layer 195 may include an elastomer, such as an acrylic-based elastomer, a butyl rubber-based elastomer, etc. In other embodiments, adhesive layer 195 may include a glue or a paste.
In accordance with an embodiment, a user may remove a block from the enclosed volume of a container section and use the block to deodorize a selected area (e.g., a room, a closet, a drawer, etc.), or part of the user's body. FIGS. 2A-2B illustrate a method of opening a section and removing a block therefrom in accordance with an embodiment. Referring to FIG. 2A, a user presses with a finger 260 on the top side of enclosed volume 125. The pressure from the user's finger 260 pushes onto the block 250 disposed within enclosed volume 125. Referring to FIG. 2B, when the user presses on the top side of the enclosed volume 125, the pressure from the user's finger 260 causes block 250 to press onto and through the aluminum foil layer 175 on the bottom side of section 110. The pressure causes the aluminum foil layer 175 to break along circular outline 140. After the aluminum foil layer 175 breaks along outline 140, block 250 can be removed from enclosed volume 125.
FIG. 3A shows block 250 in accordance with an embodiment. Block 250 includes layer 190 and layer 195. Immediately after block 250 is removed from section 110, a layer of aluminum foil 175 remains attached to layer 195.
FIG. 3B shows a block in accordance with another embodiment. Block 300 includes layers similar to those shown in FIG. 3A; however, semi-solid layer 190 is the middle layer. Adhesive layer 195 is adjacent to one side of layer 190, and aluminum foil layer 175 is adjacent to the opposite side of layer 190.
While the blocks shown in the Drawings are circular or approximately circular, blocks may have other shapes. Thus, blocks similar to those described herein may have an oval shape, a square shape, a rectangular shape, etc.
In accordance with an embodiment, a block may be attached to a selected surface and used to deodorize a selected location. FIGS. 4A-4B show a method of attaching a block to a selected surface in accordance with an embodiment. Referring to FIG. 4A, a user removes aluminum foil layer 175, exposing adhesive layer 195. The user may now stick block 250 onto a selected surface, using adhesive layer 195 to ensure that block 250 sticks to the surface. For example, the user may place the adhesive layer 195 of the block against the surface; the adhesive adheres to the surface, causing the block to remain in place. For example, a user may place block 250 on a surface inside the rim of a garbage can 283, as shown in FIG. 4B. After block 250 is attached to the inside surface of garbage can 283, deodorizing layer 190 is exposed to the air and begins to emit one or more chemicals or a deodorizing fragrance. For example, semi-solid layer 190 may emit one or more chemicals that mask the odors of garbage. Alternatively, semi-solid layer 190 may emit a desired fragrance. In another illustrative example, a user may place block 250 on an inside surface of a drawer 408, as shown in FIG. 4C. In this manner, the user may ensure that the drawer maintains a desired odor. In some embodiments, the semi-solid material of layer 190 gradually dissipates, disintegrates, or dissolves through exposure to the air.
In other embodiments, a block may be attached to other surfaces, such as a surface inside a drawer, a surface inside a suitcase or other item of luggage, a surface under a table, a surface in a bathroom, a surface in an automobile, etc.
In another embodiment, a block similar to those described herein may include semi-solid containing a material or chemical that may be placed or rubbed onto the skin or other part of the body, such as a deodorant material, an antiperspirant material, a perfume, an insect repellent, etc. In a manner similar to that described herein, a user may remove the block from a section 110 and touch or rub the semi-solid layer against his or her skin to cause some or all of the deodorant material, antiperspirant material, insect repelling material, or perfume to make contact with the skin. When a sufficient amount of the material or chemical contacts the skin and/or remains on the skin, the user may benefit from the odor-related properties of the material or chemical.
Because container 100 and sections 110 are relatively small in size and weight, a user may advantageously carry container 100, or one or more individual sections 110, in a pocket or purse and have quick access to a deodorant, an antiperspirant, an insect repellent, a perfume, etc.
In other embodiments, blocks similar to those shown in FIGS. 3A-3B and described with reference to FIGS. 3A-3B may be provided using other forms or within other forms of packaging. For example, sections holding blocks may be provided in a form similar to a roll of tape. FIG. 5 shows a roll 500 of roll sections in accordance with an embodiment. More particularly, a strip 502 includes a plurality of attached roll sections 510 that can be rolled into a compact roll 500. In one embodiment, roll sections 510 are of equal length; in other embodiments, roll sections may have different lengths. Each roll section 510 is connected to a succeeding roll section along a perforation 532. Roll 500 may be partially unrolled, and a single roll section 510 may be detached by tearing the section off along the perforation 532. In one embodiment, a single roll section is between 1.0 inch and 2.0 inches in length and less than 1.0 inch in width. Other dimensions may be used.
FIG. 6A shows a roll section 510 in accordance with an embodiment. Roll section 510 is similar to a section 110 shown in FIGS. 1A-1C. Thus, roll section 510 includes an enclosed volume 525. FIG. 6B shows a cross-section of the roll section of FIG. 6A. Roll section 510 includes a base layer 672 of paper, plastic, or similar material which surrounds enclosed volume 525. A layer 675 of aluminum foil covers the bottom surface of roll section 510. The top side of enclosed volume 525 is sealed by a layer of plastic 683. Enclosed volume 525 contains a block that includes a semi-solid layer 690, which may be a deodorizing substance, for example, and an adhesive layer 695. In the illustrative example, plastic layer 683 is vacuum sealed around layers 690, 695; therefore, no pocket of air remains inside enclosed volume 525. In other embodiments, a pocket of air may remain inside enclosed volume 525.
A block made of layers 690, 695 may be removed from roll section 510 in a manner similar to that described in FIGS. 2A-2B. Therefore, a user may use a finger to push the block through the foil layer 675, peel off the foil layer that remain attached to adhesive layer 695, and place the block in a desired location.
In accordance with another embodiment, a roll includes a plurality of blocks 625 attached to a base layer at regular intervals (or at different intervals). FIG. 6C shows a cross-section of a roll section in accordance with an illustrative embodiment. Roll section 610 holds a block 625. Referring to FIG. 6D, roll section 610 includes a strip comprising a base layer 663, which may be paper, plastic, aluminum foil, or any other suitable material, and a block 625. Block 625 includes a semi-solid layer 690 and an adhesive layer 695; adhesive layer 695 is attached directly to layer 663. In this embodiment, block 625 is not covered by a plastic layer. Nevertheless, advantageously, semi-solid layer 690 is protected (and not exposed to air during storage) because the strip of sections is stored in the form of a roll; thus each block 625 is covered by another portion of the strip. Also advantageously, a user may use one or two fingers to remove block 625 directly from the top surface of section 610 by peeling block 625 away from layer 663. The user may then place block 625 in a desired location.
In accordance with another embodiment, an odor-, fragrance- or chemical-releasing substance is provided in the form of an adhesive tape. FIG. 7A shows a roll of tape in accordance with an embodiment. Roll 700 includes a rolled strip of flexible tape 715. FIG. 7B shows a cross-section of tape 715 in accordance with an embodiment. Tape 715 includes a layer 722 of adhesive material and a layer 724 of a semi-solid material. For example, semi-solid layer 724 may include a deodorizing substance, an antiperspirant material, a sanitizing material, a perfume, a sterilizing material, an air freshening material, an insect repellent material, etc. Layer 722 is adjacent to and attached to layer 724. FIG. 7C shows a cross-section of tape 715 in accordance with another embodiment. Tape 715 includes a layer 722 of adhesive material and a layer 724 of a semi-solid material. In this embodiment, tape 715 also includes a layer 728 of aluminum foil. Thus, adhesive layer 722 is between and adjacent to semi-solid layer 724 and aluminum foil layer 728. Layers 722, 724, 728 may be configured in a different order than described herein. For example, a layer of semi-solid material may be disposed between an adhesive material and a layer of aluminum foil.
In accordance with an embodiment, a user may unroll a desired length of tape 715 and tear off, or cut off a piece of the tape with scissors, for example. If necessary, the user may remove the aluminum foil layer 728, and then attach the piece of tape to a selected surface, such as a surface on a trash can, a surface in a drawer, a surface in an automobile, etc. Adhesive layer 722 adheres to the selected surface and causes the piece of tape remain in place. While the piece adheres to the surface, semi-solid layer 724 releases a desired odor or chemical.
In accordance with an embodiment, roll 700 may be stored in a dispenser similar to a tape dispenser, as shown in FIG. 7D. Dispenser 760 is similar to a well-known tape dispenser. Roll 700 is placed in dispenser 760. Tape 715 is unrolled and cut using a sharp edge 762 of dispenser 760, in a well-known manner.
In accordance with another embodiment, a plurality of blocks may be attached end-to-end to form a cylinder-shaped stick. FIG. 8A shows a stick 800 that includes a plurality of blocks 810 in accordance with an embodiment. Each block 810 includes a layer 898 of aluminum foil, a layer 895 of an adhesive material, and a layer 890 of a semi-solid material, which may include a deodorizing material, an antiperspirant material, a sanitizing material, a perfume, a sterilizing material, an air freshening material, an insect repellent material, etc. A user may use one or several fingers to pull off a single block 810 off the stick 800, as shown in FIG. 8A. In other embodiments, a block 810 may include other layers, or the layers 898, 895, 890 may be present in a different order than that shown in FIG. 8A. For example, a block may include a layer of a semi-solid, a layer of aluminum foil on one side of the semi-solid layer, and an adhesive layer on the opposite side of the semi-solid layer. In other embodiments, a stick may have a different shaped cross-section. For example, a stick may have a square, rectangular, oval, or star-shaped cross-section.
In accordance with an embodiment, stick 800 may be stored in a container such as that shown in FIG. 8B. Stick container 850 is similar to a well-known lipstick holding container. Thus, stick container 850 includes a cylindrical body 860, a cap 867, and a twisting mechanism 863. Stick container 860 is adapted to hold stick 800.
In a well-known manner, a user may remove cap 867, as shown in FIG. 8C, and then turn twisting mechanism 863 to force one end of stick 800 to exit from cylindrical body 860. For example, a portion (not shown) of twisting mechanism 863 may be disposed within cylindrical body 860. Turning the twisting mechanism 863 may cause the portion inside the cylindrical body 860 to move within the cylindrical body and push stick 800 toward the opening of cylindrical body 860. After a sufficient length of stick 800 has emerged from cylinder 860, the user may use one or several fingers to pull off a block 810. The user may then place block 810 in a selected location by placing the adhesive layer 895 against the surface, as discussed herein.
Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
