  As shown in FIG. 1, the saucer-equipped pump container 1 according to the first embodiment of the present invention includes a container body 2. The container body 2 is formed in a bottomed cylindrical shape including a bottom 2a and a cylindrical side wall 2b extending upward from the outer peripheral edge of the bottom 2a, and the upper end thereof is open. In the illustrated case, the container body 2 is formed of a resin material in the shape of a bottomed cylindrical jar (open-ended bottle). In addition, the container main body 2 can also be made into not only resin but glass and metal. The bottom 2a of the container body 2 is provided with a vent 2c for taking in the outside air.

  A partition member 3 made of resin, for example, is attached to the container body 2, and the opening of the container body 2 is covered by the partition member 3. As shown in FIG. 2, the partition member 3 has a substantially disk-shaped partition main body 3a and a cylindrical mounting cylindrical portion 3b extending upward from the outer peripheral edge of the partition main body 3a, and protrudes from the mounting cylindrical portion 3b The stepped portion 3 c abuts on the upper end of the side wall 2 b of the container body 2 and is mounted on the container body 2. Preferably, an annular seal 4 is mounted between the step 3c and the upper end of the side wall 2b to prevent the contents from leaking out. The upper end side of the mounting cylindrical portion 3b is fitted and fixed to the U-shaped portion 5a of the fixing member 5, and the fixing member 5 is screwed to an external thread portion 2d provided on the side wall portion 2b of the container body 2 at the internal thread portion 5b. By doing this, the partition wall member 3 is fixed to the container main body 2.

  At the axial center of the bulkhead 3a, an outflow hole 3d of the contents is provided so as to penetrate the bulkhead 3a from the front to the back (upper and lower).

  As shown in FIG. 1, an inner plate 6 made of resin, for example, is provided inside the container body 2. The inner plate 6 is formed in a substantially disk-like outer shape, and a seal portion 6a which is in contact with the inner peripheral surface of the side wall portion 2b of the container body 2 over the entire circumference is integrally provided at the outer peripheral edge. The inner plate 6 is vertically movable or movable up and down in the container main body 2 by the seal portion 6a sliding on the inner peripheral surface of the side wall portion 2b. A portion defined and formed between the partition member 3 and the inner plate 6 inside the container body 2 is a housing space 7, and the container body 2 is configured to store the contents in the housing space 7. . As the inner plate 6 moves up and down, the volume of the storage space 7 is increased or decreased.

  It is preferable that the contents accommodated in the accommodation space 7 of the container body 2 be contents having relatively high viscosity, such as cream-like cosmetics such as liquid foundation and cleansing cream, and gel-like cosmetics.

  As shown in FIG. 2, a cylinder 10 is provided on the upper surface of the partition wall member 3. The cylinder 10 is formed in a cylindrical shape, and is coaxially disposed with the circularly formed outflow hole 3 d to surround the outflow hole 3 d. That is, the space of the inner part of the cylinder 10 is continued to the outflow hole 3d. In the illustrated case, the cylinder 10 is integrally formed with the partition wall member 3, but the cylinder 10 may be formed separately from the partition wall member 3 and fixed to the partition wall member 3.

  Inside the cylinder 10, a piston guide 11 made of resin, for example, is accommodated so as to be movable up and down. The piston guide 11 functions as a pump for suctioning the contents from the accommodation space 7 of the container body 2 and discharging the contents to the outside in cooperation with the cylinder 10. As shown in FIG. 2, the piston guide 11 includes a disk-shaped pressing wall 11a and a side wall 11b extending upward from a portion slightly radially inward from the outer peripheral edge of the pressing wall 11a. It has a bottomed cylindrical shape. By arranging such a piston guide 11 in the cylinder 10, the pressurizing chamber 12 connected to the outflow hole 3d is partitioned between the pressurizing wall portion 11a of the piston guide 11 and the partition main body 3a of the partition member 3. It is formed.

  The inner side of the piston guide 11 is an inflow chamber 13 defined by the piston guide 11. Further, the side wall 11 b of the piston guide 11 is provided with an inflow hole 11 c that allows the inflow chamber 13 to communicate with the pressure chamber 12.

  On the upper portion of the piston guide 11, a flange member 14 made of, for example, resin is provided. As shown in FIG. 2, the flange member 14 protrudes outward in a radial direction from the fixing portion 14 a with respect to the piston guide 11 from the fixing portion 14 a fitted and fixed to the upper end of the piston guide 11. The flange main body portion 14b, a projection piece 14c projecting upward to the outer peripheral edge of the upper surface of the flange main body portion 14b, a cylindrical guide wall 14d extending downward to the outer peripheral edge of the lower surface of the flange main body portion 14b An auxiliary guide wall 14f is integrally provided on the inner side of 14d coaxially with the guide wall 14d. A locking projection 14e protruding radially outward is integrally provided at the lower end of the guide wall 14d, and the locking projection 14e is engaged with the lower end of the U-shaped portion 5a of the fixing member 5 The flange member 14 is prevented from coming off.

  A biasing member 15 is provided between the upper surface of the bulkhead 3a and the lower surface of the flange body 14b. In the present embodiment, the biasing member 15 is a compression coil spring, and the elastic force of the biasing member 15 is transmitted to the piston guide 11 via the flange member 14. That is, the piston guide 11 is biased upward by the biasing member 15. A cylindrical support cylindrical portion 16 is integrally provided coaxially with the cylinder 10 on the outer peripheral side of the cylinder 10 on the upper surface of the partition main body 3 a coaxially with the cylinder 10, and the lower end side of the biasing member 15 is attached to the outer side of the support cylindrical portion 16 Thus, the radial position is defined by the support cylindrical portion 16. Further, the biasing member 15 has a radial position defined by the sub guide wall 14 f of the flange member 14.

  In the illustrated case, the biasing member 15 is provided between the flange member 14 fixed to the piston guide 11 and the bulkhead 3a, but the piston guide 11 may be biased upward. For example, provided between the bulkhead 3a and the piston guide 11, between the other member fixed to the piston guide 11 and the bulkhead 3a, or supported by the piston guide 11 and the bulkhead 3 Various configurations can be adopted, such as providing between the two components. Further, the biasing member 15 is not limited to the compression coil spring, but may be a leaf spring, rubber, etc. as long as it can be provided between the partition member 3 and the piston guide 11 to bias the piston guide 11 upward. The thing of various composition, such as elastic body, can be used.

  The partition wall member 3 is mounted with a check valve 20 for opening and closing the outflow hole 3 d. The check valve 20 is made of resin, and as shown in FIG. 2, an annular base 20a fitted and fixed to the inner surface of the cylinder 10, and a plurality of elastically deformable connection pieces 20b on the base 20a. And a disc-shaped valve body 20c connected thereto. For example, the check valve 20 can be configured as a three-point valve in which the valve body 20c is connected to the base 20a by three crank-like connection pieces 20b. In the normal state (the state where the discharge operation for discharging the contents is not performed), the check valve 20 covers the outflow hole 3d from the upper surface side of the partition main body 3a to close the outflow hole 3d. And the flow of contents from the pressure chamber 12 to the accommodation space 7 is blocked. On the other hand, in the check valve 20, the valve body 20c moves upward with respect to the upper surface of the partition main body 3a due to the deformation of the connection piece 20b with respect to the flow of contents directed from the accommodation space 7 to the pressurizing chamber 12. The outlet 3d is opened to allow the flow of the contents.

  The piston 21 is attached to the piston guide 11. The piston 21 can slide on the inner surface of the cylinder 10 and is guided by the piston guide 11. When the piston guide 11 descends, the inflow hole 11c is opened, and when the piston guide 11 ascends the inflow hole 11c. Operate to close. More specifically, as shown in FIG. 2, the piston 21 is formed of a seal body having an H-shaped cross section by an elastic body, and is in sliding contact with the inner surface of the cylinder 10 on the outer peripheral side thereof and pressurizing the piston guide 11. The piston guide 11 is vertically movable between the wall portion 11 a and the lower end of the fixing portion 14 a of the flange member 14. Then, when the piston guide 11 descends, the pressure wall portion 11a also moves downward to be separated from the piston 21 to open the inflow hole 11c, and the inflow chamber 13 is communicated with the pressure chamber 12 through the inflow hole 11c. Let On the other hand, when the piston guide 11 ascends, the piston 21 abuts against the pressure wall portion 11a to close the inflow hole 11c, thereby blocking the communication between the inflow chamber 13 and the pressure chamber 12. Reference numeral 22 denotes a regulating member which is fitted and fixed between the cylinder 10 and the support cylindrical portion 16 to regulate the upper moving stroke end of the piston 21.

  A discharge hole 23 for discharging the content flowing into the inflow chamber 13 to the outside is provided in the upper portion of the piston guide 11, and a resin receiving member 40 for receiving the content discharged from the discharge hole 23 Is attached. As shown in FIG. 2, the saucer member 40 includes a saucer main body 41 whose upper surface is a saucer surface 41 a, and the saucer member 40 is fitted to the upper portion of the fixing portion 14 a of the flange member 14. By fitting the saucer member 40 and the fixing portion 14a, as shown in FIG. 3, the pressing force applied to the saucer member 40 is transmitted to the piston guide 11 via the flange member 14. The tip of the seal main body 42a of the seal member 42 made of, for example, an elastic resin, fitted and fixed to the outer peripheral surface of the projection piece 14c of the flange member 14 is press-contacted on the saucer surface 41a of the upper surface of the saucer main body 41 Close contact.

  As shown in FIG. 1, a cap C that covers the saucer member 40 and the seal member 42 can be attached to the container body 2. The cap C can be detachably attached to the container body 2 by, for example, undercut engagement with the outer peripheral surface of the U-shaped portion 5a, but the container body 2 can be formed by other means such as screw connection. It can also be configured to be removably attached to the

  In the saucer-equipped pump container 1 having such a configuration, the discharge hole 23 is closed by the seal member 42 in the normal state. From this state, the saucer main body 41 or the seal member 42 is depressed downward to operate the piston guide 11 via the flange member 14, and the container body by the pump operation by the piston guide 11, the cylinder 10 and the piston 21. The contents accommodated in the accommodation space 7 of 2 can be discharged onto the receiving surface 41 a of the receiving body 41 through the pressure chamber 12, the inflow chamber 13 and the discharge hole 23.

  Under normal conditions, the check valve 20 is closed, so when the piston guide 11 is lowered and the pump operation is started, the inside of the pressure chamber 12 is pressurized by the piston guide 11 and the piston guide 11 The piston 21 mounted on the is moved as shown in FIG. 3 to open the inflow hole 11c. Then, when the piston guide 11 further descends, the pressurized content in the pressure chamber 12 flows from the inflow hole 11 c into the inflow chamber 13 inside the piston guide 11 and is discharged through the inflow chamber 13. 4B from the discharge hole 23 to the upper surface of the flange main body portion 14b and the lower surface of the saucer main body 41 so as to pass through the discharge flow path between the flange member 14 and the saucer main body 41 as shown in FIG. After going up along the side wall of the projection piece 14c through the gap, the lower surface of the seal main body 42a is directed radially inward, and then the self-closing force by the elasticity of the tip of the seal main body 42a is exceeded. It is discharged toward the By directing radially inward so as to bypass the flow path of the contents, it is possible to prevent the contents from being scattered outside.

  As described above, by pushing down the saucer main body 41 or the seal member 42 downward, the discharge hole 23 is opened and the piston guide 11 is operated to make contents from the discharge hole 23 to the saucer surface 41 a of the saucer main body 41 Can be discharged. The contents discharged to the saucer surface 41a can be used by wiping with, for example, a sponge or the like. When the content is wiped with a sponge, the content discharged from the discharge hole 23 is made to easily adhere to the sponge by pressing the sponge toward the saucer surface 41 a to depress the saucer main body 41. It is possible to easily take out the contents. Further, the seal main body 42a is formed in an annular shape covering the side surface of the projection piece 14c over the entire circumference, and the flat cross section of the seal main body 42a is formed into an annular shape (ring shape). Since it can be discharged in a ring form from the inner edge, it becomes possible to apply the sponge uniformly.

  After the contents are discharged from the discharge hole 23, when the depression operation of the saucer main body 41 or the seal member 42 is released, the seal member 42 made of a thin resin having elasticity is brought into pressure contact with the saucer surface 41a and closely attached. The discharge holes 23 are closed.

  On the other hand, when the depression operation of the saucer main body 41 or the seal member 42 is released, the elastic force of the biasing member 15 causes the piston guide 11 to move upward toward the initial position shown in FIG. At this time, since the piston guide 11 ascends in a state where the inflow hole 11 c is closed by the piston 21, the pressurizing chamber 12 becomes negative pressure, the check valve 20 is opened, and the accommodation space of the container main body 2 The content stored in 7 flows out from the outlet 3 d into the pressure chamber 12 and is supplied to the pressure chamber 12. In addition, as the contents flow out of the housing space 7, the inner tray 6 ascends inside the container body 2, and the housing space 7 is always maintained in a state of being filled with the contents. At this time, the outside air is introduced from the vent hole 2 c to the lower side portion of the inner tray 6 of the container body 2 by the amount of movement of the inner tray 6. Therefore, even if the contents are discharged, the air does not flow into the storage space 7 of the container main body 2, and the piston guide 11 is efficiently pumped by the push-down operation of the saucer main body 41 to always efficiently operate the contents. It can be discharged.

  As described above, in the pump container 1 with a saucer according to the present invention, in the normal state, the discharge hole 23 is reliably closed by the seal member 42, and the discharge is performed only when the content is discharged. Since the holes 23 are opened, air can be reliably prevented from flowing from the discharge holes 23 when not in use, and the contents can be accommodated without being exposed to the air. Thus, for example, the contents which are easily solidified by touching the air, the contents which lose their efficacy by touching the air, etc. are accommodated in the pump container 1 with a saucer without causing discharge failure or deterioration of the contents. can do.

  FIG. 5 is a cross-sectional view of a second embodiment of the saucer-equipped pump container 1 of the present invention. In FIG. 5, members corresponding to the members described above are denoted by the same reference numerals.

  In the receiver-equipped pump container 1 according to the second embodiment, as shown in FIG. 5, the seal member 42 arranges the film 42b on the lower surface of the seal main body 42a, and the film 42b press-contacts the saucer main body 41. . By using the film 42b, the adhesion between the seal member 42 and the saucer main body 41 can be enhanced. In the present embodiment, when the seal member 42 is fitted and fixed to the projection piece 14c, the film 42b is sandwiched and fixed between the upper end portion of the projection piece 14c and the lower surface of the seal main body 42a. In order to make the fixation of the film 42b more rigid, heat sealing to the seal main body 42a, adhesion with a melt (adhesive) agent or the like, or welding with ultrasonic waves or a laser may be performed. Moreover, it is preferable to make the flat cross-sectional shape of the film 42b into a ring shape similarly to the seal | sticker main body 42a.

  As mentioned above, although the structure of the present invention, the operation, and the effect were explained along the embodiment, the embodiment of the present invention is not limited to the above-mentioned embodiment.

  For example, in the embodiment, the seal main body 42a and the film 42b of the seal member 42 are formed in an annular shape, but the seal main body 42a and the film 42b are in close contact with the saucer surface 41a. As long as the discharge holes 23 can be closed, various shapes can be used.

  Furthermore, although the case where the inner plate 6 is provided in the container body 2 has been described in the above embodiment, the present invention is not limited to this. The inner layer body containing the contents without the inner plate 6 is described. It is formed in a two-layer structure housed in the inside of the body, and the double container and the peeling of the lamination which let outside air be taken in from the air hole 2c between the outer layer and the inner layer at the time of discharging the contents and shrink only the inner layer. Containers can also be used.

  The pump container with a tray according to the present invention can reliably prevent the inflow of air from the discharge hole, and can accommodate the contents without touching the air, and can be applied to a wide field as a pump container with a tray can do.
