in a generic sense , it is the purpose of this invention to provide a device in the form of a highly portable dispenser , including separate and distinct deformable reservoirs effective for segregating a two - part chemical system until the desired time of use , and containing a combination applicator nozzle and blending manifold . illustrative of materials useful for the reservoir are a plasticized foil , a low - density polyethylene or the like . materials useful for the applicator nozzle are polymers such as polypropylene or polyethylene . these materials are merely illustrative , and not limiting . the invention contemplates the use of any suitable materials of construction . in one particular embodiment , the invention will provide a kit inclusive of the device and a two - part chemical system including acetic acid and hydrogen peroxide . in the illustrated , albeit non - limiting embodiments , the device is depicted as having a clam - shell like structure , wherein there are provided first and second halves , which are each designed to rotate about an axis defined by a blending manifold . each half contains a sealed deformable reservoir filled with a distinct fluid , each respectively representing one part of a two - part chemical system . initial rotation of each half about its axis , from an initial closed or storage position , to a semi - opened position , results in exposure of an applicator nozzle . the applicator nozzle may have at least one , and as illustrated , albeit not limited thereto , a plurality of orifices . the applicator nozzle is adapted for insertion within a body cavity . upon further rotation of the first and second halves about their axes , the sealed reservoirs are breached causing them to become fluidically coupled with their respective blending manifold leg , which , in turn , is in fluid communication with the applicator nozzle . via continued rotation , pressure is brought to bear upon the deformable reservoirs , forcing fluid therefrom , and subsequently through the blending manifold assembly , thereby facilitating intermixing of the two distinct fluids . this intermixing results in activation of the two - part chemical system . the continued application of pressure results in compression and deformation of the reservoirs , thereby facilitating expulsion of the now blended and activated chemical system , under pressure , through a plurality of circumferentially spaced orifices in the applicator nozzle , enabling effective treatment of the body cavity . while the two - part chemical system can be any system designed to treat a body cavity , in an illustrative , albeit non - limiting embodiment , the system is a blend of acetic acid and hydrogen peroxide , formulated to enable normalization of ph levels and mitigation of bacterial vaginosis when instilled in a human vagina . in order to show efficacy of the two - part chemical system , formed from acetic acid and hydrogen peroxide , for mitigating the effects of bacterial vaginosis , the following experiment was conducted . the objective was to evaluate the response of patients complaining of vaginal discharge who received a vaginal rinse solution composed of hydrogen peroxide and acetic acid . a total of 294 patients complaining of vaginal discharge were tested then treated with the combined hydrogen peroxide / acetic acid vaginal rinse then reevaluated for safety and effectiveness of treatment . the results indicated that 82 % of patients who received a combined hydrogen peroxide / acetic acid vaginal rinse experienced a positive therapeutic result for the complaint of vaginal discharge . it was concluded that combined hydrogen peroxide / acetic acid vaginal rinsing provides a safe and effective low cost improvement to women with undesirable vaginal discharge . 294 patients were seen in a private office setting over a 24 - month period complaining of vaginal discharge . 92 of these patients also reported experiencing vaginal discomfort ranging from itching to a burning sensation . none of these patients were experiencing active vaginal bleeding nor did any have any visible lesions , ulcer , or abrasions , as they would have been excluded from the study . 40 of the patients were pregnant , 22 were in the third trimester and 18 were in the second trimester . 136 of the patients were white , 110 were hispanic , and 48 were african american . 10 of these patients had been diagnosed with diabetes mellitus . on the initial visit , patients underwent a speculum evaluation , vaginal ph testing and vaginal culture and sensitivity testing . this was followed by the insertion of 90 milliliters ( 3 ounces ) of an aqueous solution consisting of 3 % hydrogen peroxide and 5 % acetic acid . the ph of the aqueous solution is 2 . 5 . an asepto syringe was used to introduce the solution . the patients were then transferred to a consultation room and any questions were answered . the patients then filled out a short card commenting on the treatment and thereby provided collectible data . patients then were given a follow up appointment in 7 to 10 days . during the follow up appointment the patients underwent a repeat speculum evaluation and ph determination . the results of their respective cultures were reviewed with the patients and if the cultures were positive , appropriate treatments were given . following this second visit , the patient was given another questionnaire to comment on the treatment . data was collected to obtain insight into safety , comfort , and response to treatment . of the 294 patients who presented with a chief complaint of vaginal discharge , 62 had a positive culture . of these positive cultures , 30 ( 48 %) had bacterial vaginosis , 25 ( 40 %) had candida species , and 7 ( 11 %) had trichomonas vaginalis . average pre - treatment vaginal ph was 5 . 1 at the first visit . average post - treatment vaginal ph was 4 . 0 . of the 294 patients , 12 reported that the treatment was uncomfortable . of these 12 who reported that the treatment was uncomfortable , 2 described the discomfort as moderately uncomfortable and 10 described the discomfort as mildly uncomfortable . none of the patients experienced appreciable erythema , swelling , or any signs suggestive of allergic reaction to the administration of the solution . of the 225 patients , which returned for their follow up visit , the average vaginal ph was 4 . 1 . none of the patients reported any subsequent rash , irritation or any symptoms suggesting an allergic reaction to the application of the solution . 184 of the 225 ( 82 %) patients that were seen during the follow up visit described the treatment as helpful . vaginal discharge is a very common medical complaint , which accounts for a significant number of women seeking medical treatment . causes of vaginal discharge include : normal physiologic variation , allergic reaction to spermicides and deodorants , vaginitis , and certain vaginal douches among others . anything that alters the relatively low vaginal ph or negatively impacts the normally present lactobacillus species that inhabit the vaginal vault can contribute to the development of undesirable vaginal discharge . of particular interest is the production of hydrogen peroxide by certain species of lactobacilli . hydrogen peroxide has known antimicrobial properties , which kills bacteria and viruses . acetic acid in low concentrations has been used for decades by a number of women in different countries as a vaginal cleanser . by merely lowering the vaginal ph , the vaginal vault is less susceptible to pathogenic bacteria . this study evaluated a combined product containing a mixture of hydrogen peroxide and acetic acid . the combined solution was introduced within the vagina to ascertain whether a positive clinical outcome could be attained . these two substances when combined in a physiologically compatible concentration were found to afford a positive physiological outcome in an ambulatory clinical setting . cost of treatment was very acceptable and treatment benefit was immediate . the instantly presented embodiments of the invention will be best understood by reference to the drawings , wherein like parts are designated by like numerals throughout . it will be readily understood that the components of the present invention , as generally described and illustrated in the figures herein , could be arranged and designed in a wide variety of different configurations . thus , the following more detailed description of the embodiments of the present invention , as represented in the figures , is not intended to limit the scope of the invention , as claimed , but is merely representative of presently preferred embodiments of the invention . the series of figures numbered 1 - 4 and 7 - 10 respectively depict a representative activation of the respective embodiments shown therein , as the device is opened and activated . the first of the series of figs . ( 1 and 7 ) show the device in a closed or storage position . it is envisioned that the device may be provided in some type of protective wrap ( not shown ) that will be removed prior to use . the second figure in the series , ( 2 and 8 ) show the device opened to the extent that the hidden applicator tip has been exposed . the third figs . ( 3 and 9 ) illustrates the deformable reservoirs coming into contact with one another , whereupon the continuous application of pressure results in discharge of the now intermixed two - part chemical mixture from at least one orifice 112 in the applicator nozzle 110 . the fourth figs . ( 4 and 10 ) illustrates the reservoirs having been completely collapsed , whereupon a prescribed dosage unit of the activated two - part chemical mixture has been expelled within the body cavity . now , with reference to fig1 , an embodiment of the invention 100 , shown in an initial closed position , is illustrated . in this embodiment , the two halves of the device 100 are mirrored images of one another . first and second main body parts 102 and 104 form the basic structure . they each contain a formed depression 107 ( see fig2 ) designed to encase applicator nozzle 110 when the device is in its closed position . first and second outer shells 109 and 113 are designed to mate with the main body parts 102 and 104 and thereby encase first and second sealed reservoirs 106 and 111 there between . the first and second sealed reservoirs 106 and 111 each contain one part of a two - part chemical system . engagement gears 116 are provided to assist in driving the blending manifold assembly 120 ( fig2 ). each blending manifold leg 114 resides within the area of rotation formed by the joining of the main body parts 102 , 104 and outer shells 109 , 113 , which thereby form a manifold retaining area , and the center thereof each respectively define the axis of rotation for their respective halves . note that in the closed position , the right ends of each blending manifold leg 114 are initially even with the outer periphery of the device 100 . referring to fig2 , the embodiment of fig1 is shown in a partially opened position . note that in this embodiment , as the rotation occurs , the blending manifold assembly 120 has begun to move from right to left so as to perforate the respective seals of the reservoirs 106 , 111 as will be more specifically illustrated in later figures . fig3 further illustrates the embodiment of fig1 opened to a point where the fluid reservoirs 106 , 111 are compressed so as to initiate flow through the circumferentially spaced orifices 112 , of applicator nozzle 110 . the embodiment showing multiple orifices 112 is merely illustrative , and it is understood that the invention contemplates any number or positioning of orifices . fig4 illustrates the embodiment of fig1 opened to a point where the fluid reservoirs 106 , 111 are depleted and flow through orifices 112 of the applicator nozzle 110 has ceased . now referring to fig5 , there is illustrated an exploded view of portions of the embodiment of fig1 . main body part 102 , having depression 107 for receiving applicator tip 110 when in a closed position is shown . bearing surfaces 118 , present on main body part 102 and outer shell 109 forms a receiving area for blending manifold assembly 120 . the receiving area defines an axis that is concurrent with the axis of rotation of each half of the device . elements 126 define at least one sharp protuberance designed to pierce reservoir bladder seals 117 . linking member 119 protrudes from reservoir 106 in order to provide fluid communication between the reservoir 106 and blending manifold assembly 120 . as the two halves of the device 100 are rotated from their closed position , the blending manifold assembly 120 translates from right to left by virtue of guide pin 122 engaging guiding groove 124 . fig6 a , 6 b , 6 c , 6 d and 6 e illustrate the traversal of the blending manifold assembly 120 as the embodiment of fig1 is opened causing the at least one seal disrupting protuberances 126 of each blending manifold leg 114 to pierce the bladder seals 117 of each fluid reservoir simultaneously . it is noted that as one observes the positioning of the blending manifold assembly 120 going from fig6 a - 6e , the movement of the ends of each blending manifold leg 114 relative to the main body of the device is readily apparent . fig6 f is an exploded view of the blending manifold assembly 120 as it relates to the manifold retaining area defined by the outer shells of the device ( see fig2 ). it more clearly illustrates the interaction of the guide pin 122 and guiding groove 124 . fig7 illustrates an alternative embodiment of the invention in an initial closed position . this embodiment is configured somewhat differently , so that both halves are identical , not mirror images . main body parts 202 and 204 form the basic structure . they contain a formed depression 207 ( see fig8 ) designed to encase applicator nozzle 110 when the device is in its closed position . outer shells 209 are designed to mate with the main body parts 202 and thereby encase deformable sealed reservoirs 206 there between . the structure of these reservoirs is identical , however each contains a different component of the two - part chemical system . the ends of each blending manifold leg 214 having a bearing surface 222 reside within the area of rotation formed by the joining of the main body parts 202 and outer shells 209 , which define a manifold retaining area , wherein the center thereof each respectively define the axis of rotation for their respective halves . fig8 illustrates the embodiment of fig7 in a partially opened position . fig9 illustrates the embodiment of fig7 opened to a point where the fluid reservoirs 206 are compressed so as to initiate flow through at least one orifice 112 therein . the embodiment as illustrated , albeit non -
