Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to rubber or latex gloves and, in particular, to a method of making same. More particularly, the present invention relates to a method of making a rubber or latex glove having a fragrance.




A rubber or latex glove is typically worn to cover a user's hand and, perhaps, arm. The glove provides protection or a physical barrier against water, detergents, and grease, especially when a user is engaged in cleaning activities, for instance, when washing dishes. It is desired that the glove be flexible to provide manual dexterity to the user. Also, each glove should be fitted properly so that it does not slide on the user's hand or permit unwanted material from entering into the glove.




Because of their barrier protection, rubber or latex gloves are typically used for tasks directed to cleaning or jobs that may be dirty or in which the hands and arms may require protection. However, when using rubber or latex gloves, the odor from the rubber or latex is very noticeable. Many individuals consider the odor to be undesirable and even somewhat objectionable.




In contrast, people generally enjoy fragrances and pleasant smells. In many situations, fragrances are used to mask or cover up objectionable odors. They can be used to distract or alter the experience one has when faced with an otherwise undesirable situation or task.




Consumer expectations must be fulfilled by the fragrance. This requires careful selection of the fragrance. Typically panel and consumer testing are performed to make the appropriate selection. Consideration is also given to the strength of the fragrance, which must be acceptable to the consumer. That is, the fragrance cannot be too strong or too weak, but must be adjusted to the proper level.




However, fragrances are expensive and must be used sparingly to keep down costs. The application of a fragrance onto a glove must be cost effective in order to avoid any unnecessary increase in the cost of the glove. Moreover, the amount of fragrance should be minimized again to avoid unnecessary increases in the cost of the glove.




2. Description of Related Art




Past attempts to incorporate a fragrance into a glove has involved adding fragrance into the latex or rubber compound. This can be an expensive proposition and an inefficient method of making such a glove. The latex or rubber must be in a liquid state. Adding fragrance to the compound, undesirably leads to fragrance volatilizing off during processing. As such, higher levels of fragrance must be added to compensate for the continual loss of fragrance. Even worse, the fragrance can be altered or destroyed by combining it with the latex or rubber.




When reviewing prior art patents, one does not learn how to effectively and efficiently apply fragrance onto a glove.




U.S. Pat. No. 3,942,193 entitled “Dental Glove” discloses a latex dental glove, where the glove body is covered in a liquid slurry. The liquid slurry contains a dusting powder, an adhesive agent, and a flavoring agent. The flavor agent imparts taste to the glove, making the presence of the glove in the mouth less objectionable. However, there is no suggestion to apply a fragrance to a glove.




U.S. Pat. No. 4,597,108 entitled “Powderfree Surgical Gloves” discloses methods for making a latex glove where the inside and outside of the glove are halogenated to impart a slippery surface to the glove. This patent does not teach how to add fragrance to the glove.




BRIEF SUMMARY OF THE INVENTION




It is an object of the present invention to provide a method for making a fragranced glove.




It is another object of the present invention to provide such a glove that has a pleasant odor that remains after the glove is used several times.




It is yet another object of the present invention to provide a method that uniformly applies fragrance to a glove.




It is a further object of the present invention to provide such a method that applies fragrance to the inside surface of the glove.




To accomplish the foregoing objects and advantages, the present invention, in brief summary, is a method for making a fragranced glove, comprising the steps of: providing a glove with an inside surface and an outside surface, applying a fragrance to the glove, tumbling the glove to evenly distribute the fragrance, and drying the glove to remove the residual fragrance.




In a second embodiment, the method for making a fragranced glove comprises the steps of: halogenating the cured glove, neutralizing and rinsing the halogenated glove; drying the rinsed glove; applying a fragrance to an exterior surface of the rinsed and dried glove; and then tumble drying the glove. Preferably, fragrance is added when the glove is rinsed. Also, preferably, the glove is drained after neutralizing and rinsing but before drying.




In a third embodiment, the glove is on a mold where the inside surface of the glove is exposed to the environment. The method includes spraying or misting fragrance onto the inside surface of the glove; stripping the glove from the mold so that the exterior surface of the glove is in its proper position; halogenating the glove; neutralizing and rinsing the halogenated glove; and then drying the glove. Preferably, the glove is drained after the glove has been neutralized and rinsed.

DETAILED DESCRIPTION OF THE INVENTION





FIGS. 1

,


2


, and


3


, show coating apparatus


200


, which is used in the preferred embodiment of the present invention. Coating apparatus


200


is used to apply and preferably spread the fragrance evenly over a glove


280


, and dry the residual fragrance from the glove. It should be understood that the fragrance can be applied as a fragrance or as a fragrance solution. Coating apparatus


200


has a rotating drum


210


, a metering pump


220


, and one or more air vent dampers


240


.




A metered dose of a fragrance solution that includes perfume, water, and an emulsifying agent is applied onto glove


280


using coating apparatus


200


. The water acts as a carrier of the perfume and the emulsifying agent creates an emulsion between the perfume and the water. The fragrance solution is formulated to enable a sufficient amount of the fragrance to be distributed evenly over glove


280


and the dosage is determined by the weight of the gloves added to drum


210


.




The emulsifying agent included in the fragrance solution can be, but is not limited to, sodium lauryl sulfate, alkylphenol-hydroxypolyoxyethylene, polysorbates, and mixtures thereof. Moreover, a water based emulsion may be used.




The fragrance solution may include about 5 wt. % to about 20 wt. % perfume, about 1 wt. % to about 5 wt. % emulsifying agent, and about 75 wt. % to about 94 wt. % water.




Glove


280


along with other gloves is placed in drum


210


of coating apparatus


200


. Drum


210


rotates at a speed, which enables glove


280


to tumble about. A speed control drive unit


250


may be used to adjust the speed of drum


210


. Preferably, drum


210


rotates at a speed such that the gloves remain in the bottom half of drum


210


to permit the spray to reach across the drum.




In

FIG. 3

, metering pump


220


moves the fragrance solution into and through one or more spray nozzles


224


to evenly spray or mist the fragrance solution into drum


210


. Pump


220


is operated to deliver the proper amount of fragrance solution. The fragrance solution is applied onto glove


280


either by direct contact on the glove or by transference, whereby gloves rub against one another to spread the fragrance. Regardless, as drum


210


slowly rotates, glove


280


is coated with the fragrance. The tumbling action also ensures that the fragrance is evenly applied over glove


280


.




Air


245


is introduced into drum


210


to dry glove


280


. Air vent damper


240


controls the airflow by adjusting the amount of air


245


that passes through. For example, air vent damper


240


is closed when applying the fragrance solution, to prevent it from escaping through the air ducts. When drying, air vent damper


240


is opened to allow air


245


to pass through and dry glove


280


. During this phase, the rotation speed of drum


210


is increased to get the gloves to become airborne, further facilitating the drying process.




In

FIG. 4

, there is provided a formed glove


310


. The formed glove


310


has been cured. The glove


310


has an inside or interior surface


315


and an outside or exterior surface (not shown).




In the embodiment shown in

FIG. 5

, glove


310


is fragranced by a method of the present invention. The glove


310


is already formed and cured as shown by step


320


. The glove


310


is stripped from a mold or glove former, as discussed in step


330


, so that the exterior surface is in its proper exterior position.




The glove


310


is then halogenated in a halogenation solution as discussed at step


340


. The preferred halogenation solution is a chlorine solution. Thereafter, the halogenated glove


310


is preferably neutralized (step


350


) and then rinsed (step


360


). It is then preferable that glove


310


is drained as shown in step


370


. In a most preferred embodiment of the embodiment depicted in

FIG. 5

, fragrance is added to the rinse so that fragrance is applied to both inside surface


315


and the outside surface of the glove. The neutralized glove


310


is then rinsed as shown in step


360


.




In a preferred embodiment, glove


310


is dried, step


380


, by conventional devices, such as, for example, a dryer. At step


395


, fragrance is applied to the exterior surface of glove


310


by spraying or misting, and the glove is then tumbled and dried.




The step of stripping glove


310


from a mold is used to reverse the surface orientation of the glove. That is, the stripping process changes the surface orientation so that the outside surface is the exterior surface and is exposed to the environment, while inside surface


315


, shown in

FIG. 4

, becomes the interior surface of glove


310


and, thus, is no longer directly exposed to the environment.




Halogenation, step


340


, is a treatment where glove


310


is dipped or placed in a solution that has a halogen, such as chlorine or bromine. Preferably, chlorine is used as the halogen. This treatment imparts a slippery feel to inside surface


315


and the outside surface, so that glove


310


can slide onto the user's hand with less resistance.




As stated above, a rinsing step


360


may also be incorporated into the method. In the rinsing step, glove


310


is placed in the rinse solution for cleaning. Most preferably, fragrance is added to the rinse solution, thereby providing an initial coating of the fragrance on glove


310


during the rinsing step.




As also stated above, glove


310


may also be neutralized, step


350


, after halogenation, but before rinsing and/or the fragrance application step. Neutralization removes halogens from inside surface


315


and the outside surface of glove


310


. Typically, neutralization is performed by immersing glove


310


in a neutralizing solution, for example an alkaline solution may be used.




The drying step


380


is any conventional drying that includes, for example, an air blower being applied for a discrete period of time in proximity to glove


310


. Drying will remove the residual rinsing solution from glove


310


.




The present invention may include a cooling step


390


that lowers the glove temperature after drying glove


310


. For example, the glove temperature may be cooled to about room temperature. In this cooling step, additional fragrance is applied onto glove


310


and the glove is tumbled. The tumbling is used to evenly coat glove


310


with fragrance. For example, glove


310


is placed in rotating drum


210


with other gloves. The rotating action tumbles glove


310


and other individual gloves around the chamber. In addition, the tumbling action leads to rubbing of individual gloves against one another. This facilitates the spreading of fragrance evenly across glove


310


.




In an alternative embodiment shown in

FIG. 6

, glove


310


is formed and cured, as shown in step


420


. The glove


310


is positioned on the mold, with inside surface


315


exposed to the environment and the outside surface in contact or positioned on the mold. Fragrance is applied, step


430


, to inside surface


315


, preferably by spraying or misting. Most preferably, the spraying or misting is with a spray nozzle


335


shown in FIG.


4


. The spray preferably forms a desired spray pattern


338


in the palm of glove


310


. However, the spray pattern can be any desired pattern. Also, although not preferred, fragrance can be sprayed on the entire inside surface of glove


310


.




After fragrance is sprayed or misted onto glove


310


, the glove is stripped, step


440


, from the mold.




The glove


310


may be halogenated, step


450


, after stripping the glove from the mold. If halogenated, glove


310


is preferably neutralized


460


and then drained


470


. Next, glove


310


is rinsed


480


in a rinse solution and then drained


490


. Whether drained or not, glove


310


is next dried, step


495


.




In this embodiment, halogenation is preferably with chlorine. Also, as with the embodiment of

FIG. 5

, fragrance may be added to the rinse solution so that when glove


310


is rinsed, step


480


, fragrance is transferred onto both inside surface


315


and the outside surface of the glove.




The glove


310


may be dried in any conventional manner including, applying an air blower for a discrete period of time in proximity to glove


310


. This drying removes the residual neutralizing and rinsing solutions from glove


310


. Also, glove


310


may be cooled. For example, glove


310


may be cooled to about room temperature. Still optionally, glove


310


may be tumbled after fragrance is applied. Furthermore, the tumbling may be incorporated into the drying step.




The present invention has been described with particular reference to the preferred forms thereof. It will be obvious to one of ordinary skill in the art that changes and modifications may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
