Product for liquid delivery fragrance samples
The product for liquid delivery fragrance samples lacks a liquid tight and a vapor tight, perimeter glue band or heat seal. The product comes from easily produced, in-line manufacturing of a commercially printable paper which has an applied barrier coating to defeat permeation by the liquid fragrance material. The product has a substantially irregular, or textured, fragrance sample material mounting and application surface that creates an occlusive, cohesive seal between the substrate layers when fragrance materials are applied. The opposing, textured substrates of the product are in close proximity where the textured surfaces defeat the capillary action of the fragrance sample, and thereby occlude the migration of the fragrance sample out from the product. Also, the inability of the fragrance to flow in conjunction with its inherent surface tension makes the fragrance sample substantially repose within the texture of the barrier coating. Then for usage, the fragrance sample is accessed by a prospective customer who opens a fold or removes a die-cut portion.
This non-provisional application claims priority to the provisional application for patent Ser. No. 61/072,974 filed Apr. 4, 2008, which is commonly owned by the same assignee.
BACKGROUND OF THE INVENTIONThis product for liquid delivery fragrance samples relates to the manufacture of a fragrance sampler page or piece and more specifically to liquid-delivery type fragrance samplers. These samplers are well known in the industry and are commonly found in magazines, used as retail handouts, or contained in advertising mailers. A unique aspect of the system is retention of a liquid fragrance sample upon the sampler using surface tension of the fragrance in cooperation with the texture of the sampler and without a perimeter weld or gluing of the sampler.
DESCRIPTION OF THE PRIOR ARTTypically, liquid-delivery type samplers comprise a liquid fragrance contained in a hermetically sealed film envelope which has a heat-sealed, or glued, perimeter so as to contain the liquid fragrance within these samplers without leaking. These samplers are generally manufactured in the form of a label comprising multiple film layers. Generally, the manufacturing process produces the samplers at slow speeds on small-format web or label presses that have been modified to suit the application. Machinery then mechanically or physically attaches the samplers to a carrier page for later incorporation into magazines or other mailings. Further, small stand-alone sampler pieces also provide handouts or flyers in retail establishments.
The liquid fragrance material carried by the sampler is generally accessed by removing, or pealing away, a laminated cover portion of the sampler. These sample devices provide to fragrance manufactures methods and devices that present a rendition of their products for trial by prospective customers. In addition, the sample pages and pieces include graphics and advertising prose printed thereon, commonly seen in printed advertising media for another viable sales instrument.
Prior art label-type pieces such as Bootman et al., U.S. Pat. No. 5,391,420, Muchin, U.S. Pat. No. 5,161,688, and, Bishopp, U.S. Pat. No. 5,439,172, teach methods of producing an effective liquid-fragrance advertising device. This type of devices rely upon a perimeter glue band, or heat seal, to prevent capillary action of the fragrance from occurring between the substrate layers of the sampler. Fragrance capillary action arises from the surface tension of the fragrance and the close proximity of the substrates and layers. Fragrance capillary action would cause leakage from within the sampler and onto the sample page, the carrier, or the magazine. Prospective customers avoid fragrances that leak from a sampler and damage a magazine. Leaky fragrance samples also lose their volatile components upon exposure to the atmosphere. The seal also aids in preventing leakage caused by compression loads, which occur with common frequency in sampler pieces that are contained in large stacks of magazines during assembly, mailing, transport, and display.
The manufacturing operations, necessary to produce these perimeter seals, require continuous process monitoring because even slight process variation can cause the perimeter seals to fail. These products also require a minimum of three expensive, discontinuous auxiliary operations to produce a finished sampler page.
More particularly, Bootman describes a pressure sensitive label comprising two plies of a film or plastic material: one bottom pressure sensitive ply, a deposit of fragrance material and an overlay of a second ply which traps the fragrance deposit. The sealing is by a perimeter heat seal. The draw back of this product is that the fragrance material is often forced into and through the seal areas under pressure from the stacking forces of many magazines, or inserts, in distribution.
Then, Muchin builds upon Bootman by introducing a center ply material which has a die-cut window. This window ply is introduced onto the bottom pressure sensitive ply and thus creates a well for the fragrance material. The top, third ply is then added and the result is that stacking forces are distributed on to the widow ply and the fragrance material is exposed to less force that would have lead to seal failures and leakage: a major defect from Bootman.
A more cost-effective method to produce liquid-delivery sample pages, or pieces, constructs the page from a commercially printable paper substrate and contains the liquid, volatile, fragrance material between layers of the substrates. By following this method, a single manufacturing platform completes the entire printing and assembling process in-line. The paper and other required materials are mounted and processed on the single line, and the finished product exits the end of the manufacturing line for packaging and then shipment.
Other prior art includes some instances of liquid fragrance delivery devices that are also produced in-line during a single operation. The patent to Charbonneau, U.S. Pat. No. 5,419,958 discloses a paper-based sampler page designed to defeat fragrance pre-release by applying a volatile liquid treatment or coating to the sample application area so as to block the penetration of fragrance oils into the paper.
This method requires sequential layers of barrier coating and involves the use of huge curing ovens to provide an adequate barrier. Most existing printing lines lack the floor space required for such additions. Therefore, the necessity exists to design and to construct a custom manufacturing line for implementation of this product.
Further, Charbonneau does not disclose any method that would prevent the fragrance material from leaking out of the sampler. The types of coatings cited by Charbonneau have high susceptibility to surface inconsistencies, known as pin-holes. The pin holes appear from vapor off-gassing during the curing stage of the process. Then the thick coatings that resist the off-gassing cause the paper to curl badly.
Then the patent to Whitaker et al., U.S. Pat. No. 5,645,161 discloses a multiplicity of construction methods. One embodiment comprises a heat-sealed perimeter that contains the liquid fragrance. Such heat sealing is a slow, cumbersome, and expensive manufacturing method. The maximum speed of the heat-seal unit falls short of the minimum operational speed of present day printing presses leading to a bottle neck of production at the heat seal unit while the presses operate at less an optimum rates. Another embodiment involves equipment that applies a patch of barrier-type film to the moving paper web of a printing press. This operation, too, would also fall behind the minimum operational speed of a modern printing press.
The patent to Jones et al., U.S. Pat. No. 6,125,614 discloses a method of manufacturing a laminated page comprising a paper substrate carrier and a film substrate barrier layer. This continuous, film-type barrier layer glues to a paper substrate web to provide impermeability to the. film. Then to defeat fragrance material capillary action between the film layers and leakage during compression loads, an additional adhesive is applied to become a perimeter seal on the film layer. Ideally, this secondary glue band requires in-line curing to avoid off-odor detectable by the prospective customer which can occur from interaction between the adhesive and the fragrance material. The fragrance is then printed onto the film, and the area of the page containing the laminated film is then folded over onto itself, forming a pouch, or envelope, containing the fragrance material. The application of the perimeter glue band requires continuous monitoring through visual inspection by workers or automated sensors of the finished pieces as they come along the manufacturing line.
Another challenge from the laminated, film and paper, construction of Jones, Whitaker, and Charbonneau, exists in the manufacturing scraps and wastes. The paper related recycle waste stream at bindery operations becomes contaminated by the film substrate during magazine edge-trimming operations. This contamination can be avoided by an expensive secondary die-cutting operation that removes the film substrate from the magazine trim-off area. This secondary operation though defeats the original economics of performing an all in-line construction.
SUMMARY OF THE INVENTIONThis sampler contains liquid fragrance within the texture of one or more substrate layers. When a material, such as a liquid, attains a steady state upon a surface, the liquid has reached a state of repose, also called a state of rest or inactivity. In that state, the liquid or other loose, cohesion-less material, comes to rest in a pile of a known geometry defined by its angle of repose which is the maximum angle of slope measured from a horizontal plane. The angle of repose is related to the coefficient of friction of the material.
The preferred embodiment of the liquid-delivery fragrance sample page or piece has a construction without a liquid tight and a vapor tight, perimeter glue band or heat seal. The liquid-delivery fragrance sampler page comes from easily produced, in-line manufacturing of a commercially printable material, preferably paper, which has an applied barrier coating to defeat permeation by the liquid fragrance material. The material of this invention, preferably paper, provides a substantially irregular, or textured, fragrance sample material mounting and application surface that self creates an occlusive, cohesive seal between the substrate layers when fragrance materials are applied between the layers. The material of the invention provides a self sealing device that retains a fragrance sample placed therein. Then at the place of usage of the sampler, the fragrance sample materials are easily accessed for trial by a prospective customer who opens a fold or removes a die-cut portion on the page of the sampler.
More particularly in this invention, the opposing, textured substrates of the sampler plies are maintained in close proximity. There, the textured surfaces modify the behavior of the deposited fragrance material so as to defeat its capillary action and, thereby, act to occlude the migration of the fragrance material from its application area out from the sampler. Also, because the textured surface contains the liquid fragrance, the inability of the fragrance to flow in conjunction with its inherent surface tension makes the fragrance material substantially repose and maintain its position within the texture of the barrier coating.
Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of the presently preferred, but nonetheless illustrative, embodiment of the present invention when taken in conjunction with the accompanying drawings. Before explaining the current embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
Therefore the object of the present invention is to provide a product for liquid delivery fragrance samples that requires no continuous perimeter heat seal or glue band in the fragrance or sample material's containment zone.
Another object of the product for liquid delivery fragrance samples is to occlude capillary action of the fragrance material by separation of the substrates using the coated substrate's texture.
Another object of the product for liquid delivery fragrance samples is to substantially fill the textured surface without affecting the position, or repose, or the fragrance sample within the textured surface by compressive loads. The reposed fragrance material remains within the application area's target zone.
Another object of the product for liquid delivery fragrance samples is to provide the fragrance material's angle of contact in the finished sampler of at least ninety degrees.
Another object of the product for liquid delivery fragrance samples is to create a cohesive seal between the substrate layers' barrier coating because of the inherent surface tension of the fragrance material, thereby substantially reducing the fragrance material's contact with the atmosphere and thus greatly reducing its ability to evaporate.
And lastly, another object of the product for liquid delivery fragrance samples is to determine the volume of the sample material contained in the sample application area by the total area of the textured surface and surface tension characteristics of the sample material.
These together with other objects of the invention, along with the various features of novelty that characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated a preferred embodiment of the invention.

The same reference numerals refer to the same parts throughout the various figures.
DESCRIPTION OF THE PREFERRED EMBODIMENTThe present art overcomes the prior art limitations by assembling a product for liquid delivery fragrance samples where the liquid fragrance remains within the surface texture of a substrate because of a high angle of contact, thus limiting the adverse effects of capillary infiltration of the fragrance into the material of the invention. The high angle of contact of the fragrance sample in relation to the material of the present invention prevents wetting of the sample into the material. The present invention utilizes a highly hydrophobic systems that induces an angle of contact exceeding ninety degrees. The present invention 10 begins with the components of a fragrance formulation selected by a fragrance house or manufacturer. The fragrance formulation is then rendered into a liquid for placement upon a sampler, or piece, as in
The liquid fragrance sample may undergo modification of its viscosity in various ways. Such modifications utilize fragrance oils or other fluids to change the resulting viscosity of the modified fragrance solution. Typically, fragrance oil has a viscosity range of about 2 to about 12 centipoise. However, the type of applicator or dispensing equipment may require thickening of the liquid, that is a higher viscosity, for proper passage of the fragrance liquid through the equipment. Most equipment operates upon liquids having a viscosity between 40 centipoise and 2400 centipoise, however, liquid viscosity in the range of 200,000 centipoise are still accommodated. The liquid fragrance of modified viscosity includes a blend of materials, or the addition of rheology modifiers, emulsions, suspensions, reacted materials, and other forms of thickened liquids. The liquid fragrance of modified viscosity may or may not have adhesive qualities.
The Applicants foresee modifying the liquid fragrance's viscosity using various components. Those components include blends of cellulose gums, cellulose derivatives, carboxymethylcellulose, sodium carboxymethylcellulose, hydroxypropylcellulose, hydroxyethylcellulose, methylcellulose, ethylcellulose or ethycell; vegetable gums, xanthan gum, acacia gum; alginates, carrageenan, alcogum; silicones, versagels, silicone fluid 200; clays, veegum, bentone gel, silicas, untreated fumed silica or Cabosil® M-5 from Eager Plastics of Chicago, Ill., specially treated fumed silica or Cabosil®TS-720, TS-630; surfactants, sodium lauryl sulfate, ammonium lauryl sulfate; fillers, calcium polycarbophil; emulsions, polyvinyl alcohol or Celvol® from Celanese Corp. of Dallas, Tex.; and suspensions, acrylic acid derivatives such as Carbopol® 940 and Ultrez® 10 from Lubrizol Corp. of Wickliffe, Ohio. One example of medication adjusts the viscosity of fragrance oil by adding ethycell at the rate of five percent by weight and mixing the solution at room temperature under high shear for five hours. This modification produces a fragrance oil with its viscosity increased to the range of 1700 to 1900 centipoise.
In the operations of this invention, the textured coating has the cosmetic sample locating within its interstices. Then mutually parallel barrier coatings layer upon and confront the textured coating. The sample remains with the textured coating because of stilting and its repose while the textured coating becomes effectively sealed by the adjacent barrier coatings. This layered arrangement of textured coating and barrier coating does not require a perimeter seal by heat or other welding methods.
Generally, the textured coating section has a pattern of spaced apart cells or a plurality of pockets. The sample page 1 also has a plurality of means to adhere the invention into a closed form including non-permanent adhesive applications, as at 6, in a pattern upon the cover 1b that maintain the barrier surfaces 3 and 4 in close proximity when the cover 1b is closed upon the base 1a as at the end of manufacturing, during shipment, and through the mail. The adhesive applications may include a pressure sensitive adhesive activated during manufacturing when the textured coating section is closed upon the barrier coating section and a repositionable glue that adheres the material of the device to itself temporarily but allows for ready separation of the parts of the device or the device from a mailpiece. The adhesive applications, 6, keep the sampler 1 closed until the cover 1b is opened from the base 1a by the prospective consumer. Additionally, either coated surface, 3, 4, or the sheet of material may have a further application of pressure sensitive adhesive that activates upon insertion of the invention into a printed material. This usage of adhesive secures the invention, when closed, upon a page or a card or into a magazine or other material as part of a consumer mailing campaign.
Alternatively, the textured coating section and the barrier coating section are located upon separate. sheets of material, such as select papers. Each sheet of material then has a barrier coating applied thereto and one sheet has the textured section applied upon its barrier coating. Though on separate sheets. the textured coating section registers with the barrier coating section of another sheet so that the individual pieces of texture retain the liquid fragrance sample within the spaces of the textured surface as later shown in
The barrier coating, or base coat, of the invention begins with an existing low odor, ultraviolet curable, cationic type varnish. Such a varnish includes RAD-KOTE product number K261 from Actega Radcure of Wayne, N.J. This varnish has a viscosity of approximately 375 centipoise. The low odor attribute of this varnish makes it preferable over coatings from other manufacturers. The barrier coating is applied on to a printed web of material using a flexographic coater with a Cyrel type printing plate. The printing plate has a smooth finish and is sized to meet the dimension of the desired application. Generally, the barrier coating is applied to the web of material in a thickness of about 0.3 to about 0.6 mils, depending on the surface finish or porosity of the web of material, commonly paper or substrate. An about 0.3 to about 0.4 mil thick application of base coat is effective on a high quality, smooth finish paper which is used in commercial printing. The coating then undergoes curing at an ultraviolet light curing station mounted directly after the flexographic coater. The intensity of ultraviolet light used relates to the desired operation speed of the press. Generally, printers provide approximately 100 watts of ultraviolet light per every 100 feet per minute of press web speed. As an example, a press running at 1000 feet per minute calls for 1000 watts of ultraviolet light curing capability.
The present invention also provides an embodiment where the prospective customer accesses the sample of fragrance through a die cut opening. The die cut opening can be in the textured coating section, the opposite barrier coating section, or both the textured coating section and the barrier coating section. In usage, the textured coating section has the sample of fragrance deposited upon it and then folded upon the barrier coating section with the die cut opening upwards. The prospective customer then removes the textured coating section within the die cut to test the fragrance.
Then
The texture coating is preferably a low odor, ultraviolet curable, cationic type adhesive. Such an adhesive includes RAD-KOTE product number K6004B from Actega Radcure of Wayne, N.J. This adhesive has a viscosity of approximately 825 centipoise. The Applicants prefer this adhesive for its ability to build height to the texture, as it possesses a greater viscosity and solids content than what is used for the base coat. Though described as an adhesive, the present invention has the adhesive cured immediately in a pattern as later shown that builds the texture of the invention.
The texture coating is also applied to the material, paper, or substrate, using a flexographic coater with a Cyrel type printing plate followed by immediate curing at an ultraviolet station as previously described. This printing plate though has a raised, or negative image, of the desired texture pattern in the appropriate size for the desired product. Generally, the texture coating is applied in a thickness ranging from about 0.25 mils to about 2.5 mils depending on the amount of fragrance loaded into the present invention. The Applicants prefer a thickness in the range of about 0.5 miles to about 1.25 mils. As an example of single sided texture delivery device includes a one square inch fragrance fluid application upon a 30 line per inch grid texture where the grid has a 1.0 mil height. This example yields a payload of approximately 0.27 fluid drams or about 0.1 milliliter. The present invention also includes textured coating upon both surfaces which doubles the fragrance payload.
Alternatively, the liquid fragrance material is applied by a flexographic coater as previously described. This printing plate though is made of a soft, closed cell foam material, such as Poron®. These plates, or pads, possess a smooth surface and a low memory attribute that enhances application repeatability, usually for adhesive application.
And then,
Following the description of the various patterns upon the coated surface 4,
In an alternate embodiment, two opposed textured surfaces, such as 4, can be used. The high points of each textured surface abut each other and form a liquid retaining seal. Preferably, the two opposed textured surfaces utilize raised cross hatch patterns that seal against each other.
From the aforementioned description, a product for liquid delivery fragrance samples has been described. The sampler product is uniquely capable of retaining a liquid fragrance sample upon a substrate within a folded cover and without a perimeter adhesive or heat seal. The sampler product may be manufactured from many materials, including but not limited to, paper, cardstock, paperboard, polymers, ferrous and non-ferrous metal foils and their alloys, and composites.
