  Hereinafter, the present invention will be described in detail with reference to the drawings.

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

  A partition wall member 3 made of, for example, resin is attached to the container body 2, and the opening of the container body 2 is covered with the partition wall member 3. As shown in FIG. 2, the partition wall member 3 has a substantially disc-shaped partition wall body 3a and a cylindrical mounting tube portion 3b extending upward from the outer peripheral edge of the partition wall body 3a, and protrudes from the mounting tube portion 3b. The step portion 3 c is attached to the container main body 2 in contact with the upper end of the side wall 2 b of the container main body 2. In addition, it is preferable to mount | wear with the annular seal 4 which prevents the leakage of the content between the step part 3c and the upper end of the side wall part 2b. The upper end side of the mounting cylinder 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 the male screw portion 2d provided on the side wall portion 2b of the container body 2 in the female screw portion 5b. Thus, the partition wall member 3 is fixed to the container body 2.

  In the axial center of the partition wall body 3a, an outflow hole 3d for contents is provided so as to penetrate the partition wall body 3a in the front and back (up and down).

  As shown in FIG. 1, an inner tray 6 made of, for example, resin is provided inside the container body 2. The inner tray 6 is formed in a substantially disk shape, and a seal portion 6 a that is in contact with the inner peripheral surface of the side wall portion 2 b of the container body 2 over the entire periphery is integrally provided on the outer peripheral edge thereof. The inner tray 6 is movable in the vertical direction inside the container body 2, that is, can be moved up and down by the seal portion 6 a sliding with respect to the inner peripheral surface of the side wall portion 2 b. A portion formed between the partition wall member 3 and the inner tray 6 inside the container body 2 serves as a storage space 7, and the container body 2 stores contents in the storage space 7. . The volume of the storage space 7 is increased or decreased by moving the inner tray 6 up and down.

  The content stored in the storage space 7 of the container body 2 is preferably a relatively high-viscosity content such as a creamy cosmetic such as a cleansing cream or a gel cosmetic.

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

  A piston guide 11 made of, for example, resin is accommodated inside the cylinder 10 so as to be movable up and down. The piston guide 11 functions as a pump that cooperates with the cylinder 10 to suck the contents from the storage space 7 of the container body 2 and discharge them to the outside. As shown in FIG. 2, the piston guide 11 includes a disk-shaped pressurizing wall portion 11 a and a side wall portion 11 b extending slightly upward from a radially inner portion from the outer peripheral edge of the pressurizing wall portion 11 a. It is formed in a bottomed cylindrical shape. By arranging such a piston guide 11 in the cylinder 10, a pressure chamber 12 connected to the outflow hole 3 d is defined between the pressure wall portion 11 a of the piston guide 11 and the partition wall body 3 a of the partition member 3. Is formed.

  Inside the piston guide 11 is an inflow chamber 13 defined by the piston guide 11. In addition, the side wall portion 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 outside of the piston guide 11, that is, the pressurizing chamber 12.

  The piston guide 11 is provided with a flange member 14 made of, for example, resin. As shown in FIG. 2, the flange member 14 includes a fixed portion 14 a that is fitted and fixed to the upper end of the piston guide 11, and a flange main body portion 14 b that protrudes radially outward from the fixed portion 14 a to the piston guide 11. The outer peripheral edge of the flange main body portion 14b is bent downward.

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

  In the illustrated case, the urging member 15 is provided between the flange member 14 fixed to the piston guide 11 and the partition wall body 3a. However, the urging member 15 is urged upward. If possible, for example, it is provided between the partition body 3a and the piston guide 11, provided between the other member fixed to the piston guide 11 and the partition body 3a, or supported by the piston guide 11 and the partition member 3. Various configurations can be employed, such as providing between the two members. Further, the urging member 15 is not limited to the compression coil spring, and may be a leaf spring, rubber or the like as long as it is provided between the partition wall member 3 and the piston guide 11 and can urge the piston guide 11 upward. The thing of various structures, such as an elastic body, can be used.

  The partition member 3 is equipped with a check valve 20 for opening and closing the outflow hole 3d. The check valve 20 is made of resin, and as shown in FIG. 2, an annular base portion 20a fitted and fixed to the inner surface of the cylinder 10 and a plurality of connecting pieces 20b elastically deformable on the base portion 20a. And a disc-shaped valve body 20c connected via the first and second discs. 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 portion 20a by three crank-shaped connecting pieces 20b. In the normal state (the state in which the discharge operation for discharging the contents is not performed), the check valve 20 has the valve body 20c covering the outflow hole 3d from the upper surface side of the partition wall body 3a and closing the outflow hole 3d. The flow of contents from the pressurizing chamber 12 toward the accommodation space 7 is prevented. On the other hand, in the check valve 20, the valve body 20c moves upward with respect to the upper surface of the partition wall body 3a due to the deformation of the connecting piece 20b with respect to the flow of the contents from the accommodating space 7 to the 12 pressurizing chamber. Then, the outflow hole 3d is opened to allow the flow of the contents.

  A piston 21 is attached to the piston guide 11. The piston 21 is slidable with respect to the inner surface of the cylinder 10, and is guided by the piston guide 11. When the piston guide 11 is lowered, the inflow hole 11c is opened. When the piston guide 11 is raised, the inflow hole 11c is closed. Operates as follows. More specifically, as shown in FIG. 2, the piston 21 is formed into a sealing body having an H-shaped cross section by an elastic body, slidably contacts the inner surface of the cylinder 10 on the outer peripheral side, and pressurizes the piston guide 11. Between the wall portion 11a and the lower end of the fixing portion 14a of the flange member 14, the piston guide 11 is movable in the vertical direction. When the piston guide 11 is lowered, the piston 21 moves upward with respect to the pressurizing wall portion 11a to open the inflow hole 11c, and the inflow chamber 13 is communicated with the pressurization chamber 12 through the inflow hole 11c. On the other hand, when the piston guide 11 is raised, the piston 21 abuts on the pressurizing wall portion 11 a to close the inflow hole 11 c and blocks communication between the inflow chamber 13 and the pressurization chamber 12. Reference numeral 22 denotes a regulating member that is fitted and fixed between the cylinder 10 and the support cylinder portion 16 and regulates the upper movement stroke end of the piston 21.

  A discharge head 30 for discharging the contents flowing into the inflow chamber 13 to the outside is provided at the upper part of the piston guide 11. As shown in FIG. 2, the discharge head 30 is made of, for example, resin, and includes a cylindrical discharge wall 30 a that is fitted and fixed to the upper portion of the piston guide 11 with the fixing portion 14 a of the flange member 14 interposed therebetween, and a discharge wall 30 a. And a circular ceiling wall 30b provided at the upper end. The top wall 30b has a slightly larger diameter than the discharge wall 30a. A discharge hole 30c that penetrates the discharge wall 30a and continues to the inflow chamber 13 is provided on the side surface of the discharge wall 30a. Although only one discharge hole 30c is shown in FIGS. 1 and 2, a plurality of discharge holes 30c are provided on the outer peripheral surface of the discharge wall 30a.

  A seal member 31 formed of an elastic body such as rubber or elastomer is attached to the discharge head 30. In the present embodiment, as shown in FIG. 2, the seal member 31 includes a seal body 31a and an urging portion 31b. The seal body 31a is attached to the side surface of the discharge wall 30a of the discharge head 30 so as to be in close contact with the side surface, and can close the discharge hole 30c. In the illustrated case, the seal body 31a is formed in an annular shape that covers the entire side surface of the discharge wall 30a of the discharge head 30 and has a rectangular cross-sectional shape so that the side surface of the discharge wall 30a is tightened. It is installed. The seal body 31a has a closed position (position shown in FIG. 2) for closing the discharge hole 30c, and an open position (position shown in FIG. 3) that moves downward relative to the discharge hole 30c and opens the discharge hole 30c. Between them, and is movable up and down along the axial direction of the discharge wall 30a.

  The seal member 31 includes an urging portion 31b that is formed integrally with the seal body 31a. As shown in FIG. 2, the urging portion 31b is formed in a thin cylindrical shape having a thickness smaller than that of the seal body 31a, and extends downward from the outer peripheral edge of the lower end of the seal body 31a. 14 is in contact with the upper surface of the fixed portion 14a. That is, the urging portion 31b is supported by the piston guide 11 via the flange member 14 at the lower end thereof. As shown in FIG. 3, the urging portion 31b is elastically deformed when the seal body 31a moves from the closed position to the open position, and urges the seal body 31a from the open position toward the closed position. The elastic force that the urging portion 31b urges the seal body 31a from the open position toward the closed position is greater than the elastic force that the urging member 15 urges the flange member 14 or the piston guide 11 upward. It is set small.

  The discharge head 30 is equipped with a resin tray member 40 that receives the contents discharged from the discharge hole 30c. As shown in FIG. 2, the saucer member 40 includes a saucer body 41 whose upper surface is a saucer surface 41a. The saucer body 41 is open to the saucer surface 41a and the top wall 30b of the discharge head 30 is disposed inside. A through hole 41b is provided.

  A cylindrical guide wall 42 extending downward is integrally provided on the outer peripheral edge of the tray body 41, and a sub guide wall 43 is integrally provided coaxially with the guide wall 42 inside the guide wall 42. The outer peripheral surface of the guide wall 42 can be slidably contacted with the inner peripheral surface of the U-shaped portion 5a of the fixing member 5, and the inner peripheral surface of the sub guide wall 43 is slidably contacted with the outer peripheral edge of the flange main body portion 14b. Thus, the tray member 40 is movable in the vertical direction along the discharge head 30, that is, can be raised and lowered. Note that a locking projection 42 a that protrudes radially outward is integrally provided at the lower end of the guide wall 42, and this locking projection 42 a is engaged with the lower end of the U-shaped portion 5 a of the fixing member 5. The tray member 40 is prevented from coming out.

  An engaging portion 44 is provided integrally with the tray body 41. As shown in FIG. 2, this engaging part 44 is comprised by the lower surface in the inner peripheral end side of the saucer main body 41, and is engaging with the upper surface of the seal main body 31a from the upper direction. A support wall 45 is integrally formed on the lower surface of the tray body 41 so as to contact the back surface of the seal body 31a and support the seal body 31a. That is, the seal member 31 is disposed between the side surface of the discharge head 30 and the support wall 45 of the tray body 41.

  With such a configuration, in the normal state shown in FIG. 2, that is, in the state where the tray body 41 is in the closed position, the top wall 30b of the ejection head 30 is arranged inside the opening of the through hole 41b, and the opening of the through hole 41b is formed. The discharge hole 30c is blocked by the seal body 31a at the closed position and is blocked from flowing in air from the discharge hole 30c.

  On the other hand, as shown in FIG. 3, the seal body 31a is closed together with the tray body 41 by pushing down the tray body 41 of the tray member 40 downward from the state shown in FIG. And the opening of the through hole 41b can be opened to open the discharge hole 30c to the outside. When the discharge hole 30c is opened to the outside, the seal body 31a of the seal member 31 seals the space between the discharge head 30 and the support wall 45 and faces downward from between the discharge head 30 and the support wall 45. Leakage of the contents is prevented.

  In addition, a press-down portion 46 is provided integrally with the tray body 41. As shown in FIG. 2, the push-down portion 46 is provided in a step shape in a portion adjacent to the outside of the support wall 45 on the lower surface of the tray body 41. As shown in FIG. 3, the push-down portion 46 is attached to the flange member 14 when the tray body 41 is lowered to the open position, that is, when the tray body 41 is lowered to the position where the seal body 31 a is the open position. A pressing force applied to the tray body 41 by contacting the contact wall 47 provided integrally from above is transmitted to the piston guide 11 via the flange member 14. In the illustrated case, the pressing portion 46 is brought into contact with the abutting wall 47 provided in the piston guide 11 so that the pressing force of the tray body 41 is transmitted to the piston guide 11 through the flange member 14. However, it is also possible to adopt a configuration in which the push-down portion 46 is brought into direct contact with the piston guide 11.

  As shown in FIG. 1, a cap C that covers the tray member 40 and the ejection head 30 can be attached to the container body 2. The cap C can be configured to be detachably attached to the container body 2 by, for example, undercut engagement with the outer peripheral surface of the U-shaped portion 5a. It can also be set as the structure detachably attached to.

  In the pump container 1 with a saucer having such a configuration, in a normal state, the discharge head 30 is housed inside the through hole 41b of the saucer body 41 and closes the opening of the through hole 41b. The discharge hole 30 c provided in the seal member 31 is closed by the seal body 31 a of the seal member 31. From this state, by pushing down the tray body 41 downward, the discharge hole 30c is opened to the outside and the piston guide 11 is operated. By the pumping operation by the piston guide 11, the cylinder 10 and the piston 21, the container body 2 The contents stored in the storage space 7 can be discharged from the discharge hole 30 c to the tray surface 41 a of the tray body 41. At this time, the elastic force of the urging portion 31b that urges the tray body 41 together with the seal body 31a is set to be smaller than the elastic force of the urging member 15 that urges the piston guide 11 upward. Therefore, when the tray body 41 is pushed down, the tray body 41 first moves downward from the closed position toward the open position, and then the push-down portion 46 contacts the contact wall 47 and the piston guide 11 moves to the tray body 41. It will be pushed down with.

  More specifically, first, when the tray body 41 is pushed down to the open position by a user or the like, the pushing force is transmitted from the engaging portion 44 to the seal body 31a, and the seal body 31a is moved to the tray body 41. At the same time, the discharge hole 30c is opened by being pushed down from the closed position shown in FIGS. 1 and 2 to the open position shown in FIG. 3 against the elastic force of the urging portion 31b. At this time, since the saucer body 41 is moved downward with respect to the top wall 30b of the ejection head 30, the ejection hole 30c is opened toward the outside, that is, the saucer surface 41a via the through hole 41b.

  Next, after the discharge hole 30c is opened as shown in FIG. 3, when the tray body 41 is further pushed downward, the pushing portion 46 provided on the tray body 41 comes into contact with the contact wall 47. Thus, the pressing force of the tray body 41 is transmitted to the piston guide 11 via the flange member 14. As a result, the piston guide 11 is lowered together with the tray body 41, and the pump operation is started.

  Since the check valve 20 is closed in the normal state, when the piston guide 11 is lowered and the pump operation is started, the inside of the pressurizing chamber 12 is pressurized by the piston guide 11 and the piston guide 11. The piston 21 attached to is moved upward and the inflow hole 11c is opened. When the piston guide 11 further descends, the pressurized content inside the pressurizing chamber 12 flows into the inflow chamber 13 inside the piston guide 11 from the inflow hole 11c, passes through the inflow chamber 13 and the discharge head. 30 and is discharged from the discharge hole 30c toward the tray surface 41a.

  In this way, by pushing down the saucer body 41 downward, the discharge hole 30c is opened to the outside, and then the piston guide 11 is operated by pushing down the saucer body 41 further downward. The contents can be discharged from the discharge hole 30 c to the tray surface 41 a of the tray body 41. The contents discharged on the tray surface 41a can be used by wiping with a sponge or the like, for example. In the case of wiping the contents with a sponge, the contents discharged from the discharge holes 30c can be easily attached to the sponge by pressing down the tray body 41 by pressing the sponge toward the tray surface 41a. The contents can be easily taken out. Further, since the contents are discharged in a ring shape from the discharge hole 30c to the tray surface 41a through the annular gap between the discharge head 30 and the through hole 41b, the contents are adhered to a wide area of the sponge. Can be further facilitated.

  After the contents are discharged from the discharge hole 30c, when the pressing operation of the tray body 41 is released, the seal body 31a moves upward to the closed position where the discharge hole 30c is closed together with the tray body 41 by the elastic force of the biasing portion 31b. Move to. Therefore, when the discharge operation of the contents is completed, the discharge hole 30c is automatically closed by the seal body 31a. When the seal main body 31a moves upward to the closed position, the tray main body 41 is pushed upward by the seal main body 31a to move to the closed position, and the opening of the through hole 41b is closed.

  On the other hand, when the pressing operation of the tray body 41 is released, the piston guide 11 moves upward toward the initial position shown in FIG. 1 by the elastic force of the biasing member 15. At this time, since the piston guide 11 is lifted with the inflow hole 11c closed by the piston 21, the pressure chamber 12 becomes negative pressure, the check valve 20 is opened, and the accommodation space of the container body 2 7 flows out from the outflow hole 3 d into the pressurizing chamber 12 and is supplied to the pressurizing chamber 12. Further, as the contents flow out of the storage space 7, the inner tray 6 rises inside the container body 2, and the storage space 7 is always maintained in a state filled with the contents. At this time, the outside air is introduced into the lower part of the middle dish 6 of the container body 2 from the vent 2c by the amount of movement of the middle dish 6. Therefore, even if the contents are discharged, air does not flow into the storage space 7 of the container body 2, and the piston guide 11 is always efficiently pumped by the depression operation of the tray body 41, so that the contents are efficiently removed. Can be discharged. The elastic force of the urging portion 31b that urges the tray body 41 together with the seal body 31a is set to be smaller than the elastic force of the urging member 15 that urges the piston guide 11 upward. Then, after the contents are discharged from the discharge hole 30c, when the pressing operation of the tray body 41 is released, first, the piston guide 11 is moved upward toward the initial position shown in FIG. The contents are moved to be supplied to the pressurizing chamber 12, and then the tray body 41 is moved upward from the open position to the closed position by the elastic force of the biasing portion 31b to close the opening of the through hole 41b. It will be.

  Thus, in the pump container 1 with a saucer of the present invention, in a normal state, the through hole 41b is closed by the ejection head 30, and when the saucer body 41 is pushed down to eject the contents. Since the contents are discharged after the discharge holes 30c are automatically opened, air can be reliably prevented from flowing in from the discharge holes 30c when not in use, and the contents can be accommodated without touching the air. can do. Thus, for example, contents that are easily solidified by contact with air or contents that become less effective when exposed to air are accommodated in the pump container 1 with a saucer without causing defective discharge or deterioration of the contents. can do.

  Further, in the pump container 1 of the present embodiment, in the normal state, the discharge hole 30c is reliably closed by the seal body 31a, and the tray body 41 is pushed down to discharge the contents. Since the seal body 31a is pushed down from the closed position to the open position by the tray body 41 to automatically open the discharge hole 30c, the seal body 31a more reliably ensures that air flows from the discharge hole 30c when not in use. The contents can be accommodated without being exposed to air.

  Furthermore, in the pump container 1 of the present embodiment, the seal body 31a is formed in an annular shape covering the entire side surface of the discharge wall 30a, and the side surface of the discharge wall 30a is tightened by the seal body 31a. Is closely attached to the side surface of the discharge wall 30a, so that the discharge hole 30c can be more reliably closed by the seal body 31a. Thereby, the inflow of air from the discharge hole 30c can be prevented more reliably.

  Further, in the pump container 1 of the present embodiment, the seal member 31 is configured such that the urging portion 31b that urges the seal body 31a from the open position to the closed position is integrally provided on the seal body 31a. Further, it is not necessary to provide another member for urging the seal body 31a, so that the number of parts of the pump container 1 with the saucer can be reduced, and the cost can be reduced.

  Furthermore, in the pump container 1 according to the present embodiment, since the urging portion 31b is formed in a cylindrical shape (skirt shape), a large elastic force can be applied to the seal body 31a that has moved to the open position. Therefore, the seal body 31a that has moved to the open position can be reliably moved to the closed position, and the inflow of air from the discharge hole 30c can be further reliably prevented.

  In order to assist the movement of the seal body 31a to the closed position by the elastic force of the urging portion 31b, as shown in FIGS. 4A and 4B, a leaf spring 50 may be provided integrally with the flange member 14. it can. The leaf spring 50 protrudes upward while extending in the circumferential direction from the flange main body portion 14b, and is in contact with the lower surface of the saucer main body 41 at the tip. By providing such a plate spring 50, the elastic force for moving the tray body 41 upward is assisted by the plate spring 50, so that the urging portion 31b more reliably moves the seal body 31a from the open position to the closed position. It is possible to further prevent the inflow of air from the discharge hole 30c. When the leaf spring 50 is integrally provided on the flange member 14, the total elastic force of the elastic force of the leaf spring 50 and the elastic force of the urging portion 31 b is smaller than the elastic force of the urging member 15. Is set to be

  FIG. 5 is a cross-sectional view of another modification of the pump container 1 with a saucer shown in FIG. 1, and FIG. 6 shows that the saucer member 40 of the pump container 1 with a saucer shown in FIG. FIG. In FIGS. 5 and 6, members corresponding to those described above are denoted by the same reference numerals.

  In the pump container 1 with a saucer of another modification shown in FIG. 5, the upper end of the top wall 30 b of the discharge head 30 is disposed below the saucer surface 4 a of the saucer body 41 in the normal state, and as shown in FIG. 6. In addition, even if the tray body 41 is lowered to the open position where the seal body 31a becomes the open position, the upper end of the top wall 30b of the discharge head 30 does not protrude upward from the tray surface 41a.

  In the configuration of this modified example, the inner peripheral surface of the through hole 41b provided in the saucer body 41 of the saucer member 40 is formed in a tapered shape having a larger diameter on the upper side than on the lower side, and the upper end of the discharge head 30, that is, the ceiling The outer peripheral surface of the wall 30b is preferably formed in a tapered shape corresponding to the through hole 41b. By adopting such a configuration, even if the top wall 30b of the ejection head 30 does not protrude upward from the tray surface 41a of the tray body 41, a sufficient gap is generated between the through hole 41b and the ceiling wall 30b. Thus, the discharge hole 30c can be reliably opened toward the tray surface 41a through the gap.

  FIG. 7 is a cross-sectional view of a pump container with a saucer according to another embodiment of the present invention, FIG. 8 is an enlarged cross-sectional view showing the main part of the pump container with a saucer shown in FIG. 7, and FIG. FIG. 7 is a cross-sectional view of the pump container with a saucer shown in FIG. 7 in a state where the saucer member is pushed down to open the discharge hole.

  The pump container 101 with a saucer shown in FIGS. 7-9 differs in the structure of the saucer member 40 and the sealing member 31 with respect to the pump 1 with a saucer shown in FIGS. As shown in FIG. 7, the other configuration of the pump container 101 with the saucer is basically the same as that of the pump 1 with the saucer shown in FIGS. 1 to 6. Therefore, in FIGS. The same reference numerals are given to the members corresponding to the members that have been made, and the re-explanation of the parts other than the above differences will be omitted.

  As shown in FIG. 8, in the pump container 101 with a saucer, the saucer body 41 of the saucer member 40 is provided with a step surface 102 between the saucer surface 41a and the support wall 45, that is, along the periphery of the through hole 41b. Yes. The step surface 102 is substantially perpendicular to the axial direction of the ejection head 30, that is, the elevation direction of the tray body 41 and is directed upward. In the normal state, the top wall 30b of the discharge head 30 abuts the step surface 102 on the lower surface 30d of the outer peripheral edge portion that protrudes radially outward from the discharge wall 30a. The opening 41b is closed by the ejection head 30. The lower surface 30d of the top wall 30b of the discharge head 30 has a stepped shape that is recessed below the outer peripheral edge portion that protrudes radially outward from the discharge wall 30a of the top wall 30b. Is provided.

  Further, in the pump container 101 with the saucer, the seal member 31 includes an annular cylinder portion 103 mounted on a side surface below the discharge hole 30 c of the discharge head 30, and a radially outer side from the upper end portion of the annular cylinder portion 103. It is set as the structure provided with the cyclic | annular lip | rip part 104 which protrudes toward this and contacts the inner surface of the through-hole 41b. In the illustrated case, since the through hole 41 b of the tray body 41 is provided inside the support wall 45, the annular lip 104 of the seal member 31 is configured to contact the inner peripheral surface of the support wall 45. ing. The annular lip 104 is elastically contacted with the inner peripheral surface of the support wall 45 while being urged radially outward, and is slidable with respect to the support wall 45. With such a configuration, the space between the side surface of the discharge head 30 and the inner peripheral surface of the support wall 45 is liquid-tightly sealed by the seal member 31 below the discharge hole 30c, and the sealed state is maintained. The saucer body 41 can be moved up and down with respect to the ejection head 30.

  As described above, in the pump container 101 with a saucer in the present embodiment, since the biasing portion 31b is not provided in the seal member 31, a member that biases the saucer member 40 upward is necessary. Therefore, in this embodiment, a spring 105 is provided between the flange member 14 and the saucer body 41, and the saucer member 40 is urged upward by the spring 105 from the open position toward the closed position. . The elastic force with which the spring 105 urges the tray body 41 from the open position to the closed position is set smaller than the elastic force with which the urging member 15 urges the flange member 14 or the piston guide 11 upward. Has been. Thus, also in the present embodiment, when the tray body 41 is pushed down, the tray body 41 first moves downward from the closed position toward the open position, and then the push-down portion 46 comes into contact with the contact wall 47. When the piston guide 11 is pushed down together with the saucer body 41, and when the push-down operation of the saucer body 41 is released, the piston guide 11 is first moved to the initial position shown in FIG. After the contents are supplied to the pressurizing chamber 12, the tray body 41 is moved upward from the open position toward the closed position by the elastic force of the spring 105, and the opening of the through hole 41b is closed. Will be.

  The means for urging the tray member 40 upward toward the closed position is not limited to the above-described spring 105, and other means such as providing a leaf spring 50 similar to that shown in FIG. Means may be used. Even in this case, the elastic force that urges the tray body 41 from the open position toward the closed position is set smaller than the elastic force that the urging member 15 urges the flange member 14 or the piston guide 11 upward. Is done.

  Also in the pump container 101 with a saucer having such a configuration, as shown in FIGS. 7 and 8, in a normal state, the through hole 41b of the saucer body 41 is closed and the through hole 41b of the discharge head 30 is opened to the outside. Therefore, it is possible to reliably prevent air from flowing in from the discharge hole 30c when not in use, and to store the contents without touching the air.

  Further, as shown in FIG. 9, the tray body 41 is pushed down and lowered to the open position, thereby opening the through hole 41 b of the tray body 41 and opening the discharge hole 30 c to the outside. The piston guide 11 is actuated by pushing down the saucer body 41 downward, and the contents accommodated in the accommodation space 7 of the container body 2 by the pumping operation by the piston guide 11, the cylinder 10 and the piston 21. Can be discharged from the discharge hole 30 c to the tray surface 41 a of the tray body 41. When the contents are discharged from the discharge hole 30c, the space between the side surface below the discharge hole 30c of the discharge head 30 and the inner peripheral surface of the support wall 45 is liquid-tightly sealed by the sealing member 31. Leakage of contents directed downward from between the discharge head 30 and the support wall 45 is prevented.

  After the contents are discharged from the discharge hole 30c, when the pressing operation of the saucer body 41 is released, the saucer body 41 is moved upward from the open position to the closed position by the elastic force of the spring 105, and the saucer body The opening of the through hole 41 b of 41 is closed by the ejection head 30. That is, when the discharge operation of the contents is completed, the through hole 41b is automatically closed by the discharge head 30, and the discharge hole 30c is blocked from the outside. Thereby, even after the discharge of the contents is finished, it is possible to reliably prevent the air from flowing in from the discharge holes 30c and to store the contents without touching the air.

  When the operation of pushing down the tray main body 41 is released, the piston guide 11 is directed to the initial position shown in FIG. 8 by the elastic force of the biasing member 15 as in the pump container 1 with the tray shown in FIGS. The check valve 20 is opened, and the contents stored in the storage space 7 of the container body 2 are supplied to the pressurizing chamber 12 from the outflow hole 3d.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope according to the claims.

  For example, in the embodiment shown in FIGS. 1 to 6, the seal member 31 is formed in a shape in which the seal body 31 a is formed in an annular shape having a rectangular cross section, and the biasing portion 31 b is formed in a thin cylindrical shape. The shape is not limited to this, and various shapes can be used as long as the discharge hole 30c can be closed by the seal body 31a and the seal body 31a can be urged upward by the urging portion 31b.

  7 to 9, the sealing member 31 includes an annular cylinder portion 103 mounted on a side surface below the discharge hole 30c of the discharge head 30, and a radially outer side from the annular cylinder portion 103. As long as it has an annular lip portion 104 that protrudes toward the surface and abuts against the inner surface of the through hole 41b, the shape thereof can be variously changed.
