a “ multi - compartment , wiper - applicator package ” according to the present invention ( fig3 ) comprises a container ( 1 ) that is capable of holding a first formulation ( m ). in the case of mascara , the container is generally a cylindrical vial having a neck ( 2 ) with a screw threaded finish . the top ( 3 ) of the neck has an orifice that allows access to the interior of the container . a novel wiper ( 10 ) is disposed in the neck ( 2 ) of the container ( 1 ). the wiper is secured in the neck of the container such that it cannot easily or accidentally be removed during normal use . generally , a tight friction fit between the wiper and container neck is sufficient to ensure this . referring to fig4 a and 4 b , a wiper may have one or more raised beads ( 11 ) that ensure sufficient retention of the wiper in the container neck . the friction fit between the wiper and container neck is as air tight as that term is generally understood in the art . a typical wiper may have a flange ( 12 ) that rests on the top ( 3 ) of the container neck , when the wiper is fully seated in the container . the wiper has an upper orifice and a lower orifice , similar to a conventional wiper . prior to first use , as shown in fig4 and 4 b , the upper and lower orifices are sealed by an upper seal ( 13 ) and a lower seal ( 14 ), respectively . the upper seal ( 13 ) closes off the upper orifice of the wiper ( 10 ) and forms an air tight and / or fluid tight seal with the wiper . preferably , the upper seal is friction fit to the wiper to achieve the air tight seal . for example , the upper seal could surround the wiper flange ( 12 ) such that the air tight connection is achieved against the exterior of the wiper . preferably , however ( and as shown in fig4 b ), the upper seal is inserted into the upper orifice of the wiper and a friction fit is achieved between the exterior of the upper seal and the interior of the wiper . this arrangement may create a more sleek , less bulky appearance . the upper seal ( 13 ) may be provided with a flange ( 15 ) that rests against the flange of the wiper ( 10 ) when the upper seal is fully seated on the wiper . however , the contact between the upper seal flange and the wiper flange is not the primary seal . the upper seal flange merely limits the depth to which the upper seal can be inserted into the wiper . the primary air tight seal occurs inside the wiper , down a distance . the upper seal also has a weakened portion ( 16 ) that can be pierced or punctured relatively easily with a sharp object . in fig4 b , the weakened portion is located a distance down , into the upper seal . the weakened portion is relative to the rest of the upper seal , which cannot be pierced or punctured as easily as the weakened portion . while an air tight friction fit exists between the upper seal ( 13 ) and the wiper ( 10 ), this fit should not be so tight that pulling the upper seal would dislodge the wiper from the container ( 1 ). simultaneously , this fit should not be so tight that it is unduly difficult for a consumer to remove the upper seal from the wiper . a person of skill in the art may , by routine experimentation , arrive at the correct air tight fit . after the upper seal is removed , it is imperative that an airtight seal be possible between the flange ( 12 ) of the wiper and the container closure . the lower seal ( 14 ) closes off the lower orifice of the wiper ( 10 ) and forms an air tight and / or fluid tight seal with the wiper . preferably , the lower seal is friction fit to the wiper to achieve the seal . for example , the lower seal could surround a lower portion of the wiper such that the air tight connection is achieved against the exterior of the wiper . preferably , however ( and as shown in fig4 b ), the lower seal is inserted into the lower orifice of the wiper and a friction fit is achieved between the exterior of the upper seal and the interior of the wiper . this arrangement may create a slimmer wiper profile , that can fit into standard container openings . the lower seal ( 14 ) may be provided with a flange ( 17 ) that rests against the base of the wiper ( 10 ) when the lower seal is fully seated on the wiper . the lower seal flange will limit the depth to which the lower seal can be inserted into the wiper . unlike the upper seal , the lower seal does not have a weakened portion that can be pierced or punctured relatively easily with a sharp object . a weakened portion in the lower seal might defeat the operation of the invention . while an air tight friction fit exists between the lower seal ( 14 ) and the wiper ( 10 ), this fit should not be so tight that it is unduly difficult for a consumer to dislodge the lower seal from the wiper . a person of skill in the art may , by routine experimentation , arrive at the correct fit . the container ( 1 ) defines a primary compartment ( 1 a ). the sealed wiper ( 10 ) creates a secondary compartment ( 18 ) which can hold a quantity of secondary ingredients ( i ). there are a number of options for assembling and filling the components . for example , the container ( 1 ) can be filled in a usual manner with a first formulation ( m ). the lower seal ( 14 ) can be affixed to the wiper ( 10 ). the wiper can be filled with a quantity of secondary ingredients ( i ). the upper seal ( 13 ) can be affixed to the wiper . then , the sealed wiper can be affixed into the container orifice . alternatively , the container ( 1 ) can be filled in a usual manner with a first formulation ( m ). the lower seal ( 14 ) can be affixed to the wiper ( 10 ). then , the partly sealed wiper can be affixed into the container orifice . then the wiper can be filled with a quantity of secondary ingredients ( i ) and the upper seal can be affixed to the wiper . once the package is filled and assembled , a closure ( 22 ) for the container is optional . the closure would screw onto the container in the usual manner , except that when fully seated , the closure would bear down directly on the upper seal flange ( 15 ), rather than on the wiper flange ( 12 ). of course , this closure does not have an applicator depending from it , as is commonly done in the art . thus , the applicator must be separately supplied , to be used after the upper ( 13 ) and lower ( 14 ) seals have been dislodged . to dislodge the upper and lower seals , a “ multi - compartment , wiper - applicator package ” according to the present invention includes a seal removal tool . one embodiment of a seal removal tool is the barbed tool of fig7 a - d . the barbed tool is capable of piercing the weakened portion ( 16 ) of the upper seal ( 13 ), then dislodging the lower seal ( 14 ), and then lifting the upper seal ( 13 ) out of the wiper . when inserted into the wiper , the pointed end of the barbed tool breaks through the weakened portion of the upper seal ( fig7 b ). the pointed end cannot so easily break through any portion of the upper seal , except the weakened portion . inserting the tool further , the tool comes to bear against the lower seal . with sufficient force that a consumer could supply by hand , the lower seal is dislodged and pushed into the primary compartment , completely separated from the wiper ( fig7 c ). at this time , the secondary ingredients fall into the primary compartment . the size and shape of the lower seal are such that it cannot , at a later time , pass through the lower orifice of the wiper . also , the dislodged lower seal in the primary compartment causes no problems when an applicator is inserted . in fact , the dislodged lower seal may serve as a mixing element , helping to mix the first formulation and the secondary ingredients . to prevent the barbed tool from inserting too far into the wiper , a portion ( 19 ) of the barbed tool comes to rest against the flange ( 15 ) of the upper seal . by “ too far into the wiper ”, we mean that the barbed tool should not be able to catch on the underside of the wiper , so as not to dislodge the wiper . once the barbed tool is resting against the flange of the upper seal , raising the barbed tool will cause one or more barbs ( 20 ) to bear against a portion of the upper seal . with sufficient force that a consumer could supply by hand , the upper seal is dislodged and removed completely from the wiper ( fig7 d ). for all intents and purposes the container now functions like a conventional mascara container with wiper . there is no damage to the wiper and no foreign material residue no the wiper . the barbed tool and upper seal can be discarded . a closure with applicator of the type well known in the art can be inserted into the container and used to seal the container , in the usual manner . a feature of the upper and lower seals is that they can be pushed or pulled out of the wiper and completely separated from the wiper . this feature is necessary so that the upper and lower seals , or any portion thereof , cannot interfere with the functioning of the wiper . for this reason , the upper and lower seals must be sufficiently rigid , so that when the lower seal is pushed by the barbed tool , or the upper seal is pulled by the barbed tool , each seal moves as a complete piece , without breaking or tearing . for this reason , thin membrane seals of paper , plastic , foil etc . are generally unlike the upper and lower seals of the present invention . it is also preferable that the functioning of the wiper is not impaired , when the upper seal ( 13 ) and lower seal ( 14 ) are removed . thus , the wiper should not be damaged by removing the seals and no foreign material should be allowed to interfere with the wiper . for example , it is preferable to effect the upper and lower airtight seals without the use of adhesives . adhesive residue on the wiper flange ( 12 ) might interfere with the air tight seal between the wiper flange a container closure . anything less than a complete air tight seal will lead to rapid dryout of the formulation , rendering the product unusable . furthermore , after the lower seal is dislodged , adhesive residue on the lower portion of the wiper might interfere with the functioning of the wiper . also , adhesives residue on the wiper could interfere with the stability of the formulation . thus , the preferred embodiment of the present invention does not form the upper and lower airtight seals in a way that would leave any foreign material on the wiper or that would otherwise interfere with the functioning of the wiper . ideally , a friction fit is used . given the availability of a secondary compartment , there are any number of secondary ingredients that a skilled formulator might want to include in the sealed wiper . such materials include any that can be effectively mixed into the first formulation at the time of first use and for which it is advantageous to delay their mixing until the time of first use . in general these include , but are not limited to colorants , actives , preservatives , desiccants and rheology modifiers . functionally , these might include : curlers , lengtheners , separators , declumpers , volumizers , deflakers , despikers , lash thickeners , desmudgers , etc . one example on active that might benefit by being kept separate from the first formulation until the time of first use is the enzyme , transglutaminase . transglutaminase has been used in eyelash products to retain the curl the lashes . however , the activity of transglutaminase depends on several factors , including the ph of the formulation in which it is disposed ( 5 to about 9 is recommended and about 6 to about 7 is particularly preferred ), exposure to heat ( should be avoided ), exposure to certain types of surfactants ( anionic surfactants adversely affect the enzyme ) and the length of time that it is exposed to these factors . thus , if the first formulation is not optimum for preserving transglutaminase activity , it would be beneficial to keep the transglutaminase separate from the first formulation until the time of first use . the transglutaminase would be protected from the adverse conditions in the first formulation for the entire shelf time of the product . after first use , the transglutaminase will not be protected , but the amount of lost activity may be acceptable over the expected use life of the product . many such instances might arise , where a benefit would be achieved by keeping one or more secondary ingredients separate from the first formulation until the time of first use . in a “ multi - compartment , wiper - applicator package ” according to the present invention , the bottle and closure - applicator are physically separate before the first use . therefore , the present invention includes a kit comprising a container with wiper as described herein , the container holding a first formulation and the wiper holding one or more secondary ingredients ; and a closure - applicator ( see fig8 ). optionally , a closure without integral applicator is also supplied with the kit . the closure without applicator can be screwed onto the container to give a more finished appearance . preferably , however , the container with wiper is sufficiently air tight without the closure . improvements to the inventions so far described can be achieved by adding features already known in the art . for example , a multi - compartment mascara package according to the present invention would be even more useful and create wider formulation possibilities if combined with a vibrating applicator . in fact , the vibrating applicator could be used , among other things , to mix the secondary ingredients into the first formulation . one example of a vibrating applicator is described in us2006 - 0032512 . another improvement is expected by combining “ multi - compartment , wiper - applicator package ” according to the present invention with a heated applicator . the heat may be useful for activating some secondary ingredients , or for lowering the viscosity of the first formulation to the allow the secondary ingredients to mix better . one example of a cosmetic applicators containing heating elements is described in us2007 - 0286665 . thus , if energy can be introduced into the container ( i . e . heat or vibration , etc ), the ability to mix ingredients at the time of first use increases the formulation possibilities many fold .
a multi - compartment , wiper - applicator package comprising a container holding a first formulation , a wiper , initially sealed at both ends and a barbed tool . within the sealed wiper is a quantity of secondary ingredients that is to be mixed with the first formulation in the container . the barbed tool is able to pierce the top seal , then dislocate the bottom seal , completely separating the bottom seal from the wiper . thereafter the barbed tool removes the top seal completely , so that , what remains , is a conventional wiper . the barbed tool can be inserted only to a defined depth in the wiper . this prevents the barbed tool from removing the wiper from the container .
