(For example, see Patent Document 1).
JP 2002-337910 A

  However, the above-described conventional container is configured to close the opening of the base where the rear end communicates with the container by completely pushing the drawn nozzle back to the original state. Therefore, the base of the base must be pressed firmly against the scalp. There was an inconvenience that the opening was not completely closed and the contents overflowed.

  The problem to be solved by the present invention is based on the fact recognition described above, and after the filling of the contents from the container is completed, the contents always flow from the container into the filling space. The purpose is to dispense a certain amount based on a predetermined usage / dose.

  The quantitative dispenser according to the present invention has a base that is tightly fixed to the mouth of the container and has an opening that leads to the inside of the container, and an opening that forms an internal space together with the base and allows the internal space to communicate with the outside. A case and a tip exposed from the opening of the case are formed, and a filling space for filling the interior space with the content introduced from the opening of the base with a certain volume is formed, and the content is poured out from the opening of the tip A non-return dispenser comprising a nozzle that performs a check valve that is pushed open by the flow of the content into the opening through the tube and introduces the content into the filling space. It is characterized by this.

  In addition, a container equipped with the quantitative dispenser according to the present invention includes a base that is closely fixed to the mouth of the container and has an opening that communicates with the inside of the container. A case having an opening to be communicated, and a leading end exposed from the opening of the case, and forming a filling space in which the content introduced from the opening of the base is filled in the internal space with a certain volume, from the opening at the leading end A container having a quantitative dispenser comprising a nozzle for pouring the contents, the container having a body portion having a restoring force, and a mouth portion connected to the body portion by squeezing the body portion A squeeze container for pressure-feeding the contents, and a check valve for introducing the contents into the filling space by opening the opening with the contents pumped from the inside of the container through the tube. thing It is an feature.

  In the present invention, the case where the nozzle is slidably held in the opening of the case and the internal space itself formed by combining the base and the case is used as the filling space is also within the scope of the claims of the present invention. Including. In this case, the internal passage for pouring the contents from the inner space from the tip is also formed in an L shape or a T shape that passes from the opening provided on the side surface of the nozzle to the tip of the nozzle, and the opening on the nozzle side surface is formed by pulling out the nozzle. While sealing, the opening on the side surface of the nozzle is opened into the internal space from the pushing and poured out.

  In the present invention, the nozzle is preferably a piston nozzle having a flange that is slidably held on the inner wall of the case and expands the filling space by pulling out the nozzle and reduces the filling space by pushing the nozzle. .

  Moreover, in this invention, it is preferable to provide at least one level | step difference which becomes a small diameter toward the front-end | tip in the internal channel which leads to the front-end | tip opening of the said nozzle. Furthermore, in the present invention, it is preferable to provide a stop at the tip opening of the nozzle.

  In addition, according to the present invention, an air introduction hole for introducing air into the container and an air reversal for introducing the air into the container by opening the air introduction hole with a negative pressure in the container. It is preferable to provide a stop valve. Particularly, in this case, the check valve is a ball valve composed of a ball member and a valve seat, and the air check valve is preferably provided integrally with the valve seat.

  In addition, according to the present invention, a cap that is detachably attached to the mouth of the case or the container is additionally provided, and the top wall of the cap is detachably engaged with the tip of the nozzle. It is preferable to provide an engaging portion for pulling out the nozzle as the cap is removed.

  In the metering dispenser according to the present invention and the container provided with the same, the base having an opening for communicating the container and the filling space is pushed open by the inflow of the contents into the opening through the tube. By providing a check valve for introducing the contents into the filling space, even if a malfunction of the nozzle occurs during pouring, the malfunction does not close the opening of the base completely due to this malfunction. It never flows out. Therefore, according to the present invention, after the filling of the contents from the container is completed, a constant amount based on a predetermined usage / dose is always dispensed without the contents flowing into the filling space from the container. can do.

  By the way, when applying a hair restorer, it is well known that it is effective to stimulate the scalp, but in such a conventional container, the content filled in the case is a constant weight of its own weight. There is also a problem that such a secondary effect cannot be obtained because it is poured out only by force.

  Therefore, in the present invention, the nozzle is a piston nozzle having a flange that is slidably held on the inner wall of the case and expands the filling space by pulling out the nozzle and reduces the filling space by pushing the nozzle. . According to such a configuration, the content in the filling space is pressurized and pumped toward the tip of the nozzle by the flange, so that the scalp and the sensitive part are stimulated and massaged by the pressure of the content poured out from the nozzle. A secondary effect is obtained.

  In the present invention, if the internal passage leading to the opening at the tip of the nozzle is provided with at least one step having a small diameter toward the tip, the pressure of the contents poured out from the nozzle is further increased. Therefore, the stimulation and massage effect given to the scalp and the sensitive part become more remarkable. Further, the same effect can be obtained by providing a stop at the tip opening of the nozzle.

  In addition, according to the present invention, an air introduction hole for introducing air into the container and an air reversal for introducing the air into the container by opening the air introduction hole with a negative pressure in the container. By providing the stop valve, it is possible to prevent deformation due to the negative pressure generated in the container. In particular, in this case, the check valve is a ball valve composed of a ball member and a valve seat, and if the air check valve is provided integrally with the valve seat, the quantitative dispenser can be miniaturized. be able to.

  In addition, in the present invention, a cap that is detachably attached to the mouth of the case or the container is additionally provided, and the top wall of the cap is detachably fitted to the tip of the nozzle. If a fitting portion for pulling out the nozzle as the cap is removed is provided, the nozzle can be pulled out without getting the hands dirty.

  Hereinafter, with reference to drawings, the container provided with the fixed quantity dispenser which is the present invention is explained in detail.

  Fig.1 (a) is a principal part enlarged view which shows the hair restorer container 1 which is one form of this invention, shows the hair restorer container 1 in an unused state on the right side of the drawing, and on the left side of the drawing. The hair-growth agent container 1 in a state ready for dispensing is shown. The hair-growth agent container 1 includes a quantitative dispenser 100 described later and a container 10 to which the quantitative dispenser 100 is attached.

  Next, the quantitative dispenser 100 will be described. In FIG. 1, reference numeral 110 denotes a base that is held and fixed to the mouth portion 12 of the container 10. The base 110 includes a top surface portion 111 that covers the opening of the container mouth portion 12, and a seal peripheral wall 112 that hangs down from the top surface portion 111 and fits into the opening of the container mouth portion 12, and the container mouth portion 12 It is closely fixed to. Further, the center of the top surface portion 111 is recessed in a cylindrical shape toward the container 10, and a rod 113 is erected integrally from the inside. Further, an opening A1 leading to the inside of the container 10 is provided at the lower end of the rod 113, and a tube 115 extending into the container 10 is connected thereto.

  Reference numeral 120 denotes a case that matches the base 110. The case 120 includes a circumferential groove 121 that fits into a peripheral wall 114 that stands integrally from the outer edge of the base top surface portion 111, and an outer wall that hangs down from the peripheral groove 121 and is undercut fitted into the container mouth portion 12. 122. The outer wall 122 has an inner space R between the base 110 and a cylindrical portion 123 having an opening A3 that allows the inner space R to communicate with the outside.

  Reference numeral 130 denotes a piston nozzle that forms a filling space R1 that fills the internal space R with the content introduced from the opening A1 of the base 110 with a constant volume. The piston nozzle 130 integrally includes a tip 131 exposed from the opening A3 of the case 120 and a flange 132 that is slidably held on the inner wall 124 of the case 120. The tip 131 and the flange 132 are provided inside the piston nozzle 130. An internal passage 133 is formed therethrough. The internal passage 133 is provided with a step 134 having a small diameter toward the tip 131, and further, a throttle 135 is provided at the tip opening A2. As a result, the piston nozzle 130 forms a filling space R1 for filling the content introduced from the opening A1 of the base 110 with a constant volume together with the base 110 and the case 120, and expands the filling space R1 by drawing it out ( On the other hand, the filling space R1 is reduced by the pushing (see the right side in FIG. 1).

  Reference numeral 140 is a check valve made of a resin having a restoring property for preventing the backflow of contents from the filling space R1 to the container 10, and a base 141 inserted into the rod 113 of the base 110; The base plate 141 and the membrane plate 142 extending in a disk shape are integrally formed, and the outer edge 142e thereof abuts on the base top surface portion 111. Accordingly, the check valve 140 forms an annular space S1 together with a recess provided at the center of the base top surface portion 111, and the pressure of the contents pumped into the space S1 becomes larger than the restoring force of the membrane plate 142. Or, it opens by the negative pressure of the filling space R1 and introduces the contents into the filling space R1, and the pressure of the contents pumped into the space S1 becomes smaller than the restoring force of the membrane plate 142, or When the negative pressure in the space R1 becomes zero, the space is closed and the introduction of the contents in the filling space R1 and the backflow thereof are blocked.

  Reference numeral 150 denotes a cap that is detachably attached to the mouth portion 12 of the container 10. The cap 150 has an inner wall 151f of the top surface portion 151, a seal peripheral wall 152 for sealing the tip opening A2 of the piston nozzle 130, and a cylindrical engagement portion 153 for detachably undercut fitting the lower end of the nozzle tip 131. And integrally. According to the engaging portion 153, the piston nozzle 130 can be pulled out with the removal of the cap 150. The separation of the piston nozzle 130 from the cap 150 can be appropriately changed based on the fitting force between the nozzle tip 131 and the engaging portion 153.

  Next, the operation of this embodiment will be described.

  First, when the user removes the cap 150 from the state shown on the right side in FIG. 1, the piston nozzle 130 is pulled out from the opening A3 of the case 120 as shown on the left side in FIG. Expand the space R1. At this time, since the tip opening A2 of the piston nozzle 130 is sealed by the seal peripheral wall 152, the filling space R1 is in a hermetically sealed state, and the filling space R1 increases as the piston nozzle 130 rises as the cap 150 is removed. A negative pressure state occurs in the filling space R1. As the negative pressure is generated, the membrane plate 142 of the check valve 140 opens upward, and the contents of the container 10 are filled with the contents from the tube 115 through the opening A1 of the base 110 and the check valve 140. Introduced into R1. When the cap 150 is removed, the negative pressure in the filling space R1 becomes zero, and the introduction of the contents ends. At the same time, the membrane plate 142 of the check valve 140 is restored and closed by its own elasticity, and the contents are introduced. And the reverse flow thereof is shut off. In this state, the container 1 is tilted and inverted, and the contents are poured out.

  Next, in the state where the pouring is completed, when further use is performed, the cap 150 is reattached and the same operation is performed, or the tip opening A2 of the piston nozzle 130 is closed with a finger or the like and the piston nozzle 130 is pulled up. The contents are introduced into the filling space R1. Alternatively, in the case where the container 10 has a recoverable body portion that can be squeezed, the piston nozzle 130 may be pulled up after the completion of pouring, and the body portion 11 of the container 10 may be squeezed with the filling space R1 expanded. The contents in the container 10 are pumped from the tube 115 to the space S1 through the opening A1 of the base 110, and the check valve 140 is opened to introduce the contents into the filling space R1. Thus, when the filling space R1 is filled with a predetermined volume, the check valve 140 is closed to block the introduction of the contents and the backflow thereof. Further, when the contents are actually poured out, the outer edge 142e of the membrane plate 142 abuts against the base top surface portion 111 even if the container 1 is tilted or inverted and the tip 131 of the piston nozzle 130 is pressed against the head. Do not open the opening A1.

  That is, in this embodiment, since the check valve 140 is provided separately from the piston nozzle 130, the opening A1 of the base 110 is not completely closed due to the malfunction of the piston nozzle 130 generated during the dispensing. Will not run out. Therefore, according to the present embodiment, after the filling of the contents from the container 10 is completed, the content does not flow from the container into the filling space R1, and a constant amount based on a predetermined usage / dose is always obtained. Can be dispensed.

  In this embodiment, when the content is actually poured out, the piston nozzle 130 is pushed toward the base 110 when the tip 131 of the piston nozzle 130 is pressed against the head. In this case, since the content in the filling space R1 is pressurized and pumped toward the nozzle tip 131 by the flange 132, the scalp and the sensitive part are stimulated and massaged by the pressure of the content poured out from the piston nozzle 130. A secondary effect of providing an effect is obtained.

  Further, in this embodiment, since the inner passage 133 leading to the tip opening A2 of the piston nozzle 130 is provided with a step 134 having a small diameter toward the tip 131, the content poured out from the piston nozzle 130. Since the pressure of the object is further increased, the stimulation and massage effect given to the scalp becomes more remarkable. Furthermore, in this embodiment, since the aperture 135 is provided at the tip opening A2 of the piston nozzle 130, the stimulation and massage effect given to the scalp becomes even more remarkable.

  By the way, since the inside of the container 10 is hermetically sealed, the negative pressure in the container 10 may increase due to a decrease due to the content being poured out, which may cause deformation. Therefore, as a modification of the present embodiment, as shown in the enlarged view of the main part of FIG. 1B, an air introduction hole A4 for introducing air into the container 10 and the air introduction hole A4 are provided in the container 10 as shown in FIG. It is preferable to provide an air check valve 160 that is opened by the negative pressure inside and introduces air into the container. This air check valve 160 is a check valve made of a resin having resilience for allowing air to be introduced into the container 10 and preventing escape of air from the container 10. When the negative pressure increases and the negative pressure becomes larger than the restoring force of the air check valve 160, it opens and introduces air into the container 10, and the negative pressure in the container 10 decreases and the restoring force of the air check valve 160 decreases. It closes when it gets smaller. In this case, deformation due to the negative pressure generated in the container 10 can be prevented.

  Next, FIG. 2 is an enlarged view of a main part showing a hair growth agent container 2 according to another embodiment of the present invention, showing the hair restoration agent container 2 in an unused state on the right side of the drawing, and on the left side of the drawing. Shows the hair-restoring agent container 2 in a state ready for dispensing. In the following description, the same parts as those in FIG.

  The quantitative dispenser 200 will be described. In FIG. 2, reference numeral 210 denotes a base that is held and fixed to the mouth portion 12 of the container 10. The base 210 has a top surface portion 211 that covers the opening of the container mouth portion 12, and a seal peripheral wall 212 that hangs down from the top surface portion 211 and fits into the opening of the container mouth portion 12, and the container mouth portion 12 It is closely fixed to. In addition, at the center of the top surface portion 211, a protrusion 213 that fixes and holds a check valve 240 (to be described later) and an annular partition wall 214 that is concentrically disposed on the outside of the protrusion 213 are erected. The part 213 is provided with an opening A1 to which a tube 115 extending into the container 10 is connected.

  Reference numeral 220 denotes a case that matches the base 210. The case 220 includes a circumferential groove 221 that fits into a peripheral wall 215 that stands integrally from the outer edge of the base top surface portion 211, and an outer wall that hangs down from the peripheral groove 221 and is undercut fitted into the container mouth portion 12. And 222. The outer wall 222 has a cylindrical portion 223 that forms an internal space R with the base 210 and has an opening A3 that allows the internal space R to communicate with the outside.

  Reference numeral 230 denotes a piston nozzle that forms a filling space R1 in which the internal space R is filled with the content introduced from the opening A1 of the base 210 with a constant volume. The piston nozzle 230 integrally includes a tip 231 exposed from the opening A3 of the case 220 and a flange 232 that is slidably held on the inner wall 224 of the case 220. The tip 231 and the flange 232 are provided therein. An internal passage 233 is formed therethrough. In particular, in this embodiment, the internal passage 233 has an annular extended inner wall 234 that forms an annular gap C between the inner wall 233 and the partition wall 214 of the base 211 on the flange 233 side. The partition wall 214 of the base 210 divides a part of the filling space R1 from an annular pressure increasing space R2 where pressure is applied to the contents. Further, the internal passage 233 is provided with a step 235 having a small diameter toward the tip 231 thereof, and further, a throttle 236 is provided at the tip opening A2. As a result, the piston nozzle 230 forms a filling space R1 that fills the content introduced from the opening A1 of the base 210 with a certain volume together with the base 210 and the case 220, and expands the filling space R1 by drawing it out ( On the other hand, the filling space R1 is reduced by the pushing (refer to the right side in FIG. 2).

  Symbol 240 is a check valve for preventing the backflow of contents to the container 10 and the generation of negative pressure in the container 10, and a valve seat 241 held and fixed to the protrusion 213 of the base 110, And a ball member 242 accommodated in the valve seat 241. As a result, the check valve 240 opens and fills the contents by the pressure of the contents pumped to the opening A1 of the base 210 larger than the weight of the ball member 242 or by the negative pressure of the filling space R1. When the pressure of the contents introduced into the space R1 and pumped into the opening A1 becomes smaller than the weight of the ball member 242 or when the negative pressure in the filling space R1 becomes zero, the contents in the filling space R1 are introduced. And the reverse flow thereof is shut off.

  In addition, the check valve 240 is integrally formed with a membrane plate 243 that spreads out in an umbrella shape from the valve seat 241, and an outer edge 243 e abuts against the inner wall of the partition wall 214. As a result, the membrane plate 243 opens when the negative pressure in the vessel 10 becomes larger than the restoring force of the membrane plate 243 and opens from the air introduction hole A4 formed between the protrusion 213 of the base 210 and the partition wall 214. When air is introduced into the container 10 and the negative pressure in the container 10 becomes smaller than the restoring force of the membrane plate 243, the container 10 is closed and the introduction of air into the container 10 is blocked.

  Reference numeral 250 denotes a cap that is detachably attached to the mouth 12 of the container 10. This cap 250 also has an inner wall 251f of the top surface portion 251 and a cylindrical engagement portion 253 in which the lower end of the nozzle tip 231 is detachably undercut fitted to the seal peripheral wall 252 that seals the tip opening A2 of the piston nozzle 230. And integrally. According to the engaging portion 253, the piston nozzle 230 can be pulled out with the removal of the cap 250. The separation of the piston nozzle 230 from the cap 250 can also be appropriately changed based on the fitting force between the nozzle tip 231 and the engaging portion 253.

  Next, the operation of this embodiment will be described.

  First, when the user removes the cap 250 from the state shown on the right side in FIG. 2, the piston nozzle 230 is pulled out from the opening A3 of the case 220 as shown on the left side in FIG. Expand the space R1. At this time, since the front end opening A2 of the piston nozzle 230 is sealed by the seal peripheral wall 252, the filling space R1 is in a sealed state. A negative pressure state occurs in the filling space R1. As the negative pressure is generated, the ball member 242 moves upward, and the contents of the container 10 are filled from the tube 115 through the opening A1 of the base 210 and the gap between the ball member 242 and the valve seat 241. It is introduced into the space R1. The negative pressure in the filling space R1 becomes zero with the removal of the cap 250, and the introduction of the contents is completed. Cut off. In this state, the container 2 is tilted and inverted, and the contents are poured out.

  Next, in the state where the pouring is completed, when further use is performed, the cap 250 is attached again and the same operation is performed, or the tip opening A2 of the piston nozzle 230 is closed with a finger or the like and the piston nozzle 230 is pulled up. The contents are introduced into the filling space R1. Alternatively, if the container 10 has a recoverable body that can be squeezed, the piston nozzle 230 may be pulled up after the pouring is completed, and the body 11 of the container 10 may be squeezed with the filling space R1 expanded. The contents in the container 10 are pumped from the tube 115 to the opening A1 of the base 210, and the ball member 242 is separated from the valve seat 241 to introduce the contents into the filling space R1. Thereby, when the filling space R1 is filled with a predetermined volume, the ball member 242 is seated on the valve seat 241 to block the introduction of the contents and the back flow thereof. Further, when the contents are actually poured out, even if the container 1 is tilted or inverted and the tip 231 of the piston nozzle 230 is pressed against the head, the ball member 242 is seated on the valve seat 241 and the opening A1 is opened. will not open.

  That is, in this embodiment, since the check valve 240 including the valve seat 241 and the ball member 242 is provided separately from the piston nozzle 230, the opening A1 of the base 210 is caused by the malfunction of the piston nozzle 230 occurring during the dispensing. Will not be completely closed and the contents will not flow out. Therefore, according to this embodiment, after the filling of the contents from the container 10 is completed, the content does not flow from the container into the filling space R1, and a constant amount based on a predetermined usage / dose is always obtained. Can be dispensed.

  In addition, the check valve 240 is provided with an air check valve formed of a membrane plate 243 integrally with the valve seat 241, so that the negative pressure in the container 10 is increased and the negative pressure is increased by the restoring force of the membrane plate 243. If it becomes larger, it opens and air is introduced into the container 10, and when the negative pressure in the container 10 decreases and becomes smaller than the restoring force of the membrane plate 243, it closes and shuts off the air. For this reason, this embodiment can also prevent deformation due to the negative pressure generated in the container 10. In particular, in this case, the check valve 240 is a ball valve including a ball member 242 and a valve seat 241, and the membrane plate 243 is integrally provided on the valve seat 241, thereby reducing the size of the quantitative dispenser. Can be achieved.

  In this embodiment, when the content is actually poured out, the piston nozzle 230 is pushed toward the base 210 when the tip 231 of the piston nozzle 230 is pressed against the head. In this case, the contents in the filling space R 1, particularly the contents in the pressure increasing space R 2, are pressed and pumped through the gap C toward the nozzle tip 231 by the flange 232. As a result, it is possible to obtain a secondary effect that the scalp can be further stimulated and massaged as compared with the quantitative dispenser 100 by the pressure of the content.

  Even in this embodiment, the internal passage 233 leading to the tip opening A2 of the piston nozzle 230 is provided with a step 235 having a small diameter toward the tip 231. Therefore, the content poured out from the piston nozzle 230 Since the pressure of the object is further increased, the stimulation and massage effect given to the scalp becomes more remarkable. Furthermore, in this embodiment, since the aperture 236 is provided at the tip opening A2 of the piston nozzle 230, the stimulation and massage effect given to the scalp becomes even more remarkable.

  The above description is only a preferred embodiment of the present invention, and various modifications can be made by those skilled in the art within the scope of the claims. For example, in the present invention, the nozzle 130 (230) is slidably held in the opening A1 of the case 120 (220), and the interior space R itself formed by combining the base 110 (210) and the case is filled.
