Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a two-fluid dispenser. 
       BACKGROUND ART 
       [0002]    Various two-fluid dispensers have been proposed which include a juxtaposed pair of aerosol cans and a dispenser tool fitted over the aerosol cans and are configured to dispense fluids contained in the aerosol cans through the dispenser tool. (Refer to Patent Literature 1, for example.) 
         [0003]    The two-fluid dispenser disclosed in Paten Literature 1 includes two aerosol cans and the dispenser tool connecting upper portions of the aerosol cans. The dispenser tool includes a nozzle communicated with a stem of each aerosol can, and the nozzle is provided in a horizontally middle portion thereof with a partition plate vertically extending to divide a space in the nozzle into left and right portions. By depressing a depression head of the dispenser tool using a lever, the stem of each aerosol can is pushed down, and fluids contained in the aerosol cans are dispensed through the nozzle. 
         [0004]    In this regard, since the space in the nozzle is divided into the left and right portions by the partition plate, the fluids from the stems are further dispensed in a form of a foam through an end of the nozzle such that the fluids have a double-layered structure in which the fluids are layered on a left side and a right side.

       SUMMARY OF THE INVENTION 
     Technical Problem 
       [0006]    In dispensing a mixture of two fluids using a two-fluid dispenser as mentioned above, when a hair dye is used as the dispensed fluids, for example, one of the fluids can have a pungent odor such as an ammonia odor. In this case, maximum reduction of the pungent odor is required. There is room for improvement in reduction of the pungent odor in the case of the conventional two-fluid dispenser in which the fluids are juxtaposed on the left and the right side.

         [0014]    A seventh aspect of the present invention resides in the two-fluid dispenser of the sixth aspect, wherein the dispenser head B 3  further includes: a casing  40  having a front surface from which the nozzle  41  protrudes; and a first and a second stem fitting tube  42  and  43  suspending from the casing  40  such that the first stem fitting tube  42  is fitted to a first stem  11   a  and the second stem fitting tube  43  is fitted to a second stem  11   b,  and wherein the fluid guide mechanism is structured by forming a lower first fluid feed chamber  55  and an upper second fluid feed chamber  56  in a front end of the casing  40  located at a rear of the nozzle  41 , by dividing a space in the casing  40  except for the first and the second fluid feed chamber  55  and  56  into a first and a second fluid compartment  46  and  47  on a right and a left side, by bringing the first fluid compartment  46  into communication with the first fluid feed chamber  55  and bringing the second fluid compartment  47  into communication with the second fluid feed chamber  56 , and by providing, at a front end of the first fluid feed chamber  55 , a first through-hole  49  communicating with the nozzle  41  and providing, at a front end of the second fluid feed chamber  56 , a second through-hole  50  communicating with the nozzle  41 , the first through-hole  49  having a smaller width than the second through-hole  50  and provided below a middle portion of the second through-hole  50 . 
         [0015]    An eighth aspect of the present invention resides in the two-fluid dispenser of the first aspect, wherein the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  surrounding the upper, a lower, a right, and a left surface of the first fluid layer L 1 . 
         [0016]    A ninth aspect of the present invention resides in the two-fluid dispenser of the eighth aspect, wherein the dispenser head B 3  further includes: a casing  40  having a front surface from which the nozzle  41  protrudes; and a first and a second stem fitting tube  42  and  43  suspending from the casing  40  such that the first stem fitting tube  42  is fitted to a first stem  11   a  and the second stem fitting tube  43  is fitted to a second stem  11   b,  and wherein the fluid guide mechanism is structured by providing a partition wall  45   c  in a middle portion of the casing  40  to divide a space in the casing  40  into a first and a second fluid compartment  46  and  47  on a right and a left side, the partition wall  45   c  including a front front-rear wall  60  extending rearward, a horizontal wall  61  extending leftward from a rear end of the front front-rear wall  60 , and a rear front-rear wall  62  extending rearward from another end of the horizontal wall  61 , by providing, at a middle portion of the horizontal wall  61 , a dispenser hole  63  for dispensing the fluid from the first fluid compartment  46  into the second fluid compartment  47 , and by providing, in front of the dispenser hole  63 , a through-hole  64  communicating with the nozzle  41 . 
       Advantageous Effects 
       [0017]    According to the present invention, the dispenser head B 3  is provided inside thereof with the fluid guide mechanism to guide the fluids from the dispenser containers to be dispensed in the form of either the foam or the viscous fluid through the nozzle  41  such that the cross-sectional pattern of the dispensed fluids has the layered structure in which at least the upper surface of a first fluid layer L 1  is covered by the second fluid layer L 2 . Accordingly, even when the dispensed first fluid layer L 1  has a pungent odor and the like, volatilization thereof is prevented by the second fluid layer L 2 . Consequently, the pungent odor is sufficiently reduced. In particular, consider that fluids that are dispensed directly onto an application surface, palms, a comb, a cup, or the like in usage are contained, such as a case of the hair dye. In this case, even when a lower surface of the first fluid layer L 1  is exposed, the exposed surface is covered by the application surface, palms, comb, cup, or the like, and it is further ensured that the odor of the dispensed fluid is reduced. 
         [0018]    Furthermore, by depressing the dispenser head B 3 , the two fluids are dispensed in the aforementioned manner. Accordingly, the dispensed fluids are extremely convenient to handle. 
         [0019]    When the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  layered on the first fluid layer L 1 , and the second fluid layer L 2  has the same width as the first fluid layer L 1 , although a right, a left, and the lower surface of the first fluid layer L 1  are exposed immediately after the dispensing, the upper surface of the first fluid layer L 1  is covered by the second fluid layer L 2 . Accordingly, the above structure provides the advantageous effect of sufficiently reducing the odor. In particular when the fluids are dispensed onto the application surface with the first fluid layer L 1  below the second fluid layer L 2 , a more remarkable advantageous effect is achieved. 
         [0020]    The third to fifth aspects provide, in addition to the above advantageous effect, a further advantageous effect that the fluid guide mechanism is formed by a highly simple structure. 
         [0021]    Furthermore, when the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  covering the upper, the right, and the left surface of the first fluid layer L 1 , although the lower surface of the first fluid layer L 1  is exposed immediately after the dispensing, the upper, the right, and the left surface of the first fluid layer L 1  are covered by the second fluid layer L 2 . Accordingly, the above structure further provides the advantageous effect of reducing the odor. In particular when the fluids are dispensed onto the application surface with the first fluid layer L 1  below the second fluid layer L 2 , a more remarkable advantageous effect is achieved. 
         [0022]    The seventh aspect also provides, in addition to the above advantageous effect, the advantageous effect that the fluid guide mechanism is formed by the highly simple structure as in the aforementioned case. Furthermore, despite the simple structure, the seventh aspect provides yet a further advantageous effect that the fluids are dispensed such that the cross-sectional pattern of the dispensed fluids is clearly divided by the first fluid layer L 1  and the second fluid layer L 2  covering the upper, the right, and the left surface of the first fluid layer L 1 . 
         [0023]    Furthermore, when the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  surrounding the upper, the lower, the right, and the left surface of the first fluid layer L 1 , the first fluid layer L 1  in its entirety, except for a front surface thereof, is surrounded by the second fluid layer L 2 . Accordingly, an even more remarkable advantageous effect of reducing the odor is achieved. 
         [0024]    Similarly to the above case, the ninth aspect provides the advantageous effect that the fluid guide mechanism is formed by the highly simple structure. Furthermore, despite the simple structure, the ninth aspect also provides yet a further advantageous effect that the fluids are dispensed such that the cross-sectional pattern of the dispensed fluids is clearly divided by the first fluid layer L 1  and the second fluid layer L 2  surrounding the upper, the lower, the right, and the left surface of the first fluid layer L 1 .

     DESCRIPTION OF EMBODIMENTS 
       [0050]    Embodiments of the present invention are described below with reference to the drawings. 
         [0051]      FIGS. 1-8  show a first embodiment of a two-fluid dispenser  1  including a pair of dispenser containers A and a dispenser tool B. Each dispenser container A includes a trunk  10 , and the trunk  10  has an upper surface from which an upwardly urged and depressible stem  11  protrudes. In the present embodiment, the pair of a first and a second dispenser container A 1  and A 2  is a pair of aerosol cans. 
         [0052]    The first and the second dispenser container A 1  and A 2  have a first trunk  10   a  and a second trunk  10   b  from which upwardly urged and depressible stems  11   a  and  11   b  protrude, respectively. Each dispenser container employs a known mechanism in which, when the stem is depressed, an internal dispenser valve is opened, and the fluid is dispensed through the stem by a gas pressure in the container, and when the stem is undepressed, the stem is upwardly displaced due to an upwardly urging force, and the internal dispenser valve is closed to prevent the fluid from being dispensed. However, the dispenser container is not limited to the aerosol can, and the dispenser container may be any container that includes a built-in pump mechanism having a cylinder and a piston as long as the container satisfies the requirements that, when the stem is depressed, the fluid is dispensed, and when the stem is undepressed, the stem is upwardly displaced due to the upwardly urging force to prevent the fluid from being dispensed. 
         [0053]    Furthermore, the fluids dispensed from the dispenser containers are required to have shape retention to form the cross-sectional pattern which is later described. Accordingly, the fluids contained in the dispenser containers are those that are dispensed in the form of either a form or a viscous fluid. The above dispensed forms may be selected depending on a known foam structure in the dispenser containers and properties of the contained fluids. 
         [0054]    The dispenser tool B includes a container fixing mount B 1 , a container fixing tube B 2 , a dispenser head B 3 , and a depression operation part B 4 . 
         [0055]    The container fixing mount B 1  serves to fix the first and the second dispenser container A 1  and A 2  by being fitted to upper circumferential surfaces of the first and the second dispenser container A 1  and A 2 . 
         [0056]    The container fixing tube B 2  includes an outer circumferential wall  30 , and a lower portion of the outer circumferential wall  30  is fitted to the circumferential surfaces of the juxtaposed first and second dispenser container A 1  and A 2  via the container fixing mount B 1 . The container fixing tube B 2  also includes a flange top wall  31  extending inward from an upper end of the outer circumferential wall  30 , and an inner circumferential wall  32  suspending from the flange top wall  31  to extend across the first and the second dispenser container A 1  and A 2  for tight binding. Furthermore, the container fixing tube B 2  includes at a front and a rear thereof a front recess  33  and a rear recess  34 , respectively. The front and the rear recess  33  and  34  are each formed by forming downward dents in the inner circumferential wall  32 , the outer circumferential wall  30 , and the flange top wall  31 . The front and the rear recess  33  and  34  each also have openings on an upper, a front, and a rear surface thereof. 
         [0057]    As shown in  FIGS. 1-7 , the dispenser head B 3  includes a casing  40  having a horizontally-oriented ellipsoidal tube shape, a nozzle  41  protruding from a front surface of the casing  40 , and a pair of a first and a second stem fitting tube  42  and  43  suspended from a right side and a left side of a lower surface of the casing  40 . The dispenser head B 3  is also provided inside thereof with a fluid guide mechanism. 
         [0058]    As shown in  FIGS. 3-5 , the dispenser head B 3  of the present embodiment is structured by forming a casing main body having a circumferential wall  40   a  and a top wall  40   b,  and forming an open bottom wall  40   c  extending from the casing main body via a pair of connection hinges  44 , and by fixing the bottom wall  40   c  to the casing main body by ultrasonic bonding at a time of assembly. 
         [0059]    The fluid guide mechanism guides the viscous fluids from the dispenser containers to be dispensed through the nozzle  41  such that a cross-sectional pattern of the dispensed fluids has a layered structure in which at least an upper surface of a first fluid layer L 1  is covered by a second fluid layer L 2 . As shown in  FIG. 8 , the present embodiment is provided with the mechanism by which the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  layered on the first fluid layer L 1 , and the second fluid layer L 2  has a same width as the first fluid layer L 1 . 
         [0060]    The fluid guide mechanism of the present embodiment is structured by providing a partition wall  45  in a middle portion of the casing  40  to divide a space in the casing  40  into a first and a second fluid compartment  46  and  47  on the right and the left side, and by providing an upper-lower partition wall  48  dividing a base end portion of the nozzle  41  into an upper base end portion and a lower base end portion to provide a first through-hole  49  for bringing the first fluid compartment  46  into communication with a lower portion of the nozzle  41  and a second through-hole  50  for bringing the second fluid compartment  47  into communication with an upper portion of the nozzle  41 . Note that the partition wall  45  of the present embodiment is integrally formed with the casing main body and configured to be fitted at a lower end portion thereof to a fitting recess  51  provided in a predetermined position of the bottom wall  40   c.    
         [0061]    The depression operation part B 4  includes a mounting frame  80  and a depression plate  81 . The mounting frame  80  is fitted to an inner surface of the inner circumferential wall  32  of the container fixing tube B 2 . The depression plate  81  is connected at a front end portion thereof to a front end of the mounting frame  80  via a hinge  82 . The depression plate  81  has at an upper rear surface thereof a depression part and has at a bottom surface thereof a depression protrusion  83  that protrudes to abut against an upper surface of the casing  40 . Accordingly, the dispenser head B 3  can be pushed down by depressing and pivoting the depression part about the hinge  82 . 
         [0062]    When the two-fluid dispenser  1  configured as above is used, the depression part is depressed to cause the depression plate  81  to pivot about the hinge  82 , so that the dispenser head B 3  is pushed down, and the first and the second stem  11   a  and  11   b  of the first and the second dispenser container A 1  and A 2  are depressed, respectively. Consequently, the first fluid dispensed from the first dispenser container A 1  through the first stem  11   a  is dispensed in the form of the foam from the first fluid compartment  46  to the lower portion of the nozzle  41  below the upper-lower partition wall  48  through the first through-hole  49 . On the other hand, the second fluid dispensed from the second dispenser container A 2  through the second stem  11   b  is dispensed in the form of the foam from the second fluid compartment  47  to the upper portion of the nozzle  41  above the upper-lower partition wall  48  through the second through-hole  50 . Thus, as shown in  FIG. 8 , the first and the second fluid are dispensed through an end of the nozzle  41  such that the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  layered on the first fluid layer L 1 , and the second fluid layer L 2  has a same width as the first fluid layer L 1 . 
         [0063]    In the above embodiment, when the first fluid layer L 1  is a volatile fluid with a pungent odor, and the second fluid layer L 2  is a non-volatile fluid without a pungent odor, the odor of the first fluid layer L 1  is reduced by the second fluid layer L 2 . In particular when a hair dye is contained as the fluids, the hair dye is dispensed directly onto the application surface or temporarily on the palms and the like, and therefore, the exposed surface of the first fluid layer L 1  is mostly covered, and the odor is further reduced. 
         [0064]      FIGS. 9-11  show a second embodiment. The second embodiment includes basically the same structure as in the embodiment shown in  FIG. 1 , except for the dispenser head B 3 . Accordingly, with the exception of the dispenser head B 3 , the same reference numerals are assigned to the same or like components, and a description thereof is omitted. Furthermore, the dispenser head B 3  also includes the same structure as in the embodiment shown in  FIG. 1  in that the dispenser head B 3  includes the casing  40 , the pair of the first and the second stem fitting tube  42  and  43  suspended from the casing  40  such that the first stem fitting tube  42  is fitted to the first stem  11   a  of the first dispenser container A 1 , and the second stem fitting tube  43  is fitted to the second stem  11   b  of the second dispenser container A 2 , and the nozzle  41  protruding from the front surface of the casing  40 . The dispenser head B 3  of the present embodiment differs in the fluid guide mechanism provided therein. In this regard, the same also applies to other embodiments described below, and the above description is omitted hereinafter. 
         [0065]    The fluid guide mechanism of the present embodiment includes a partition wall  45   a  that vertically extends in a front-to-rear direction in a middle portion of the casing  40 . The partition wall  45   a  includes a cross-sectional structure having a lower vertical wall  52 , a horizontal wall  53  extending from an upper end of the lower vertical wall  52 , and an upper vertical wall  54  standing from another end of the horizontal wall  53 , and the partition wall  45   a  divides a space in the casing  40  into the first and the second compartment  46  and  47  on the right and the left side. Furthermore, a front end of a space below the horizontal wall  53  communicates with a lower base end portion of the nozzle  41  through a through-hole at a base end opening position of the nozzle  41  provided on the casing circumferential wall  40   a,  and a front end of a space above the horizontal wall  53  similarly communicates with an upper base end portion of the nozzle  41 . 
         [0066]    In the above embodiment, the first fluid dispensed from the first dispenser container A 1  is dispensed in the form of the foam from the first fluid compartment  46  to the lower base end portion of the nozzle  41  through the space below the horizontal wall  53 . On the other hand, the second fluid dispensed from the second dispenser container A 2  is dispensed in the form of the foam from the second fluid compartment  47  to the upper base end portion of the nozzle  41  through the space above the horizontal wall  53 . Thus, similarly to the embodiment shown in  FIG. 1 , the first and the second fluid are dispensed through the end of the nozzle  41  such that the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  layered on the first fluid layer L 1 , and the second fluid layer L 2  has a same width as the first fluid layer L 1 . 
         [0067]      FIGS. 12-15  show a third embodiment. In the fluid guide mechanism of the present embodiment, a first fluid feed chamber  55  on a lower side and a second fluid feed chamber  56  on an upper side are defined by a partition wall  57  and the casing bottom wall  40   c  in a front end of the casing  40  located at a rear of the nozzle  41 . The first and the second fluid feed chamber  55  and  56  each have a flat cuboid shape. Furthermore, a partition wall  45   b  extending from a rear right end of the partition wall  57  to the casing circumferential wall  40   a  is provided to divide a space in the casing  40  except for the first and the second fluid feed chamber  55  and  56  into the first fluid compartment  46  on the right side and the second fluid compartment  47  on the left side. 
         [0068]    The first fluid feed chamber  55  is provided with an aperture on the right side thereof, and the second fluid feed chamber  56  is provided with a communication hole at a rear end thereof. Through the aperture, the first fluid compartment  46  communicates with the first fluid feed chamber  55 , and through the communication hole, the second fluid compartment  47  communicates with the second fluid feed chamber  56 . Moreover, the first fluid feed chamber  55  communicates at a front end thereof with a lower base end portion of the nozzle  41  and the second fluid feed chamber  56  communicates at a front end thereof with a upper base end portion of the nozzle  41 , through through-holes at the base end opening position of the nozzle  41  provided on the casing circumferential wall  40   a.    
         [0069]    In the above embodiment, the first fluid dispensed from the first dispenser container A 1  is dispensed in the form of the foam from the first fluid compartment  46  to the lower base end portion of the nozzle  41  through the first fluid feed chamber  55 . On the other hand, the second fluid dispensed from the second dispenser container A 2  is dispensed in the form of the foam from the second fluid compartment  47  to the upper base end portion of the nozzle  41  through the second fluid feed chamber  56 . Thus, similarly to the embodiment shown in  FIG. 1 , the first and the second fluid are dispensed through the end of the nozzle  41  such that the cross-sectional pattern of the dispensed fluids comprises the first fluid layer L 1  and the second fluid layer L 2  layered on the first fluid layer L 1 , and the second fluid layer L 2  has a same width as the first fluid layer L 1 . 
         [0070]      FIGS. 16-20  show a fourth embodiment. In the fluid guide mechanism of the present embodiment, the lower first fluid feed chamber  55  and the upper second fluid feed chamber  56  are defined by a partition wall  57   a  and the casing bottom wall  40   c  in the front end of the casing  40  located at the rear of the nozzle  41 . The first and the second fluid feed chamber  55  and  56  each have a flat cuboid shape. Furthermore, the partition wall  45   b  extending from the rear right end of the partition wall  57   a  to the casing circumferential wall  40   a  is provided to divide a space in the casing  40  except for the first and the second fluid feed chamber  55  and  56  into the first fluid compartment  46  on the right side and the second fluid compartment  47  on the left side. Moreover, the first fluid feed chamber  55  is provided with an aperture on the right side thereof, and the second fluid feed chamber  56  is provided with a communication hole at the rear end thereof. Through the aperture, the first fluid compartment  46  communicates with the first fluid feed chamber  55 , and through the communication hole, the second fluid compartment  47  communicates with the second fluid feed chamber  56 . Moreover, the first through-hole  49  communicating with the nozzle  41  is provided at the front end of the first fluid feed chamber  55  on the casing circumferential wall  40   a,  and the second through-hole  50  communicating with the nozzle  41  is provided at the front end of the second fluid feed chamber  56  on the casing circumferential wall  40   a.  The first through-hole  49  has a smaller width than the second through-hole  50  and provided below a middle portion of the second through-hole  50 . 
         [0071]    The first fluid dispensed from the first dispenser container A 1  is dispensed in the form of the foam from the first fluid compartment  46  to a lower middle base end portion of the nozzle  41  through the first fluid feed chamber  55  and the first through-hole  49 . On the other hand, the second fluid dispensed from the second dispenser container A 2  is dispensed in the form of the foam from the second fluid compartment  47  to an upper base end portion of the nozzle  41  through the second fluid feed chamber  56  and the second through-hole  50 . In this regard, the first fluid is dispensed to the lower middle base end portion and the second fluid is dispensed to the upper base end portion such that a width of the first fluid is smaller than that of the second fluid, and therefore, both side portions of the second fluid intrude into the right and the left side of the first fluid when the fluids are dispensed into the nozzle  41 . As a result, as shown in  FIG. 20 , when dispensed through the nozzle  41 , the first and the second fluid have the cross-sectional pattern comprising the first fluid layer L 1  and the second fluid layer L 2  covering the upper, a right, and a left surface of the first fluid layer L 1 . 
         [0072]    In the above embodiment, when the first fluid layer L 1  is a volatile fluid with a pungent odor, and the second fluid layer L 2  is a non-volatile fluid without a pungent odor, the odor of the first fluid layer L 1  is further reduced by the second fluid layer L 2 . 
         [0073]      FIGS. 21-24  show a fifth embodiment. In the fluid guide mechanism of the present embodiment, a partition wall  45   c  is provided in the middle portion of the casing  40  to divide a space in the casing  40  into the first fluid compartment  46  on the right side and the second fluid compartment  47  on the left side. The partition wall  45   c  includes a front front-rear wall  60  extending rearward, a horizontal wall  61  extending leftward from a rear end of the front front-rear wall  60 , and a rear front-rear wall  62  extending rearward from another end of the horizontal wall  61 . 
         [0074]    Furthermore, a dispenser hole  63  for dispensing a fluid from the first fluid compartment  46  into the second fluid compartment  47  is provided at a middle portion of the horizontal wall  61 , and in front of the dispenser hole  63 , a through-hole  64  communicating with the nozzle  41  is provided. 
         [0075]    The first fluid dispensed from the first dispenser container A 1  is further dispensed in the form of the foam from the first fluid compartment  46  into the nozzle  41  through the dispenser hole  63  and the through-hole  64 . On the other hand, the second fluid dispensed from the second dispenser container A 2  surrounds the first fluid in front of the horizontal wall  61 , and further passes to the through-hole  64  to be dispensed into the nozzle  41  in the form of the foam while still surrounding the first fluid. As a result, as shown in  FIG. 24 , when dispensed through the nozzle  41 , the first and the second fluid have the cross-sectional pattern comprising the first fluid layer L 1  and the second fluid layer L 2  surrounding the upper, a lower, the right, and the left surface of the first fluid layer L 1 . 
         [0076]    In the above embodiment, when the first fluid layer L 1  is a volatile fluid with a pungent odor, and the second fluid layer L 2  is a non-volatile fluid without a pungent odor, it is further ensured that the odor of the first fluid layer L 1  is reduced by the second fluid layer L 2 .
