Description

  The present invention relates to a pump container with a saucer that discharges contents contained in a container body onto a saucer surface of a saucer member.

  Conventionally, as a container for storing relatively high-viscosity contents such as rekit foundations and cleansing creams, it is easy to use the discharged contents for a sponge or the like. A pump container with a saucer that can discharge the contents stored in the saucer toward the saucer member from a discharge hole that opens to the saucer member is often used (see, for example, Patent Document 1).

Japanese Patent No. 4112163

  However, the conventional pump container with a saucer has a configuration in which the discharge hole is always opened by the saucer member and closed by closing the overcap, so that air easily flows from the discharge hole. . For this reason, for example, when contents that are easily solidified by contact with air are stored, the contents may block the discharge holes, resulting in defective discharge. There were problems such as the possibility of deterioration of contents.

  An object of the present invention is to solve such problems, and an object of the present invention is to reliably prevent the inflow of air from the discharge holes and accommodate the contents without touching the air. An object of the present invention is to provide a pump container with a saucer.

  The pump container with a saucer of the present invention has a container body formed in a bottomed cylindrical shape, a partition member attached to the container body and covering the opening of the container body, and a discharge hole through which the contents are discharged.

Thus, it is preferable that the outer peripheral end of the sheet member on the fixed end side is in contact with the surface of the saucer surface formed in a curved concave shape, while being a fixed end side.

  In the pump container with a saucer of the present invention, in the above configuration, a support member is configured by inserting a column portion suspended from the lower surface of the disk-shaped holding portion into the discharge hole, and the lower surface of the holding portion is formed into a thin circular shape. What was used as the fixing | fixed part which fixes the inner peripheral end of the formed sheet | seat member is preferable.

  In another configuration of the present invention, in the pump container with a saucer having the main configuration described above, a fixing portion is provided at the outer peripheral end of the saucer body, and the outer peripheral end of the sheet member formed in a thin ring shape is fixed to the upper surface of the fixing portion. It is preferable that the inner peripheral end of the sheet member on the fixed end side and the free end side is disposed so as to be in contact with the surface of the tray surface.

  Moreover, the pump container with a saucer of the present invention has a saucer surface provided on the upper surface of the large-diameter disc shape and a groove part formed on the outer peripheral side of the saucer surface in the above configuration, and is suspended from the lower surface of the retainer part. And a supporting member that constitutes a holding member, and the sheet member is disposed opposite to the groove portion, and the inner peripheral end of the sheet member is in contact with the surface of the tray surface at a position closer to the axial center than the inner peripheral end of the groove portion.

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

  As shown in FIG. 1, the pump container 1 with a saucer which is the 1st Embodiment of this invention is provided with the container main body 2. As shown in FIG. 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 O of the partition wall main body 3a, a content outflow hole 3d is provided so as to penetrate the partition wall main 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 mechanism A that cooperates with the cylinder 10 to suck the contents from the accommodation space 7 of the container body 2 and guide 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. Further, 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 pressurizing chamber 12.

A resin tray member 40 having a cylindrical shape is provided on the top of the piston guide 11. As shown in FIG. 2, the upper surface of the saucer member 40 includes a saucer body 41 having a curved concave saucer surface 41 a that gradually becomes shallower from the center side toward the peripheral edge. A fixed portion 46 having a convex circular shape is projected on the upper surface of the projection. As shown in FIG. 4, for example, a cross-shaped outflow groove 47 is formed on the surface of the fixed portion 46, and a discharge hole 41 b penetrating the tray body 41 in the vertical direction is formed in the center of the outflow groove 47. Has been.
Further, an engaging portion 44 and a support wall 45 fitted and fixed to the upper end of the piston guide 11 are formed concentrically on the lower surface of the tray body 41, and an outer peripheral edge projects an annular locking portion 43 that protrudes downward. Are integrally formed.

  A biasing member 15 is provided between the lower surface of the tray main body 41 and the upper surface of the partition wall main body 3a. 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 tray body 41. That is, the tray body 41 is biased upward by the biasing 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. The radial position of the upper end side of the urging member 15 is defined by the annular locking portion 43 of the tray body 41.

  In the case shown in the figure, the urging member 15 is provided between the saucer body 41 of the saucer member 40 fixed to the piston guide 11 and the partition wall body 3a, but the piston guide 11 faces upward. If it can be biased, for example, it is provided between the partition wall main body 3a and the piston guide 11, provided between the other member fixed to the piston guide 11 and the partition wall main body 3a, or on the piston guide 11 and the partition wall member 3. Various configurations can be employed, such as provision between another member to be supported. 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 accommodation space 7 toward the pressurizing chamber 12. 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. It can move up and down with respect to the piston guide 11 between the wall portion 11 a and the lower end of the support wall 45. Then, when the piston guide 11 is lowered, the piston 21 also moves the pressurizing wall portion 11a downward so that the piston 21 is separated from the piston 21 to open the inflow hole 11c, and the inflow chamber 13 is opened through the inflow hole 11c. 12 to communicate. On the other hand, when the piston guide 11 is raised, the piston 21 comes into contact with the pressurizing wall portion 11a to close the inflow hole 11c, and the communication between the inflow chamber 13 and the pressurization chamber 12 is blocked. 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.

  The sheet member 30 is fixed to the surface of the fixing portion 46 of the tray member 40. The sheet member 30 is formed of a thin circular film sheet or the like, and the lower surface of the central portion of the sheet member 30 and the surface of the fixing portion 46 are fixed. However, the sheet member 30 and the outflow groove 47 are maintained in an unfixed state. Such fixing of the sheet member 30 to the surface of the fixing portion 46 is, for example, well-known such as welding fixing using ultrasonic waves or laser, heat welding fixing by heat sealing, or adhesive fixing using a hot melt adhesive or other adhesives. Means can be used.

  As shown in FIG. 4, the sheet member 30 has a larger diameter than the fixed portion 46. As shown in FIGS. 2 and 3, the center side of the sheet member 30 is in a fixed end state fixed to the surface of the fixing portion 46, and the outer peripheral end 31 side is in a cantilevered free end state. Thus, it is possible to come into contact with the curved concave surface 41a in a ring shape. That is, a portion where the curved concave receiving surface 41a of the receiving body 41 and the outer peripheral end 31 of the sheet member 30 are opposed to each other in a ring form the discharge port 48 of the pump container 1 with a receiving tray, and the outer periphery of the sheet member 30 The ring-shaped discharge port 48 is closed by the end 31 coming into contact with the tray surface 41a. A gap S is formed between the lower surface of the sheet member 30 and the tray surface 41 a so as to follow the curved concave shape, and the gap S and the central discharge hole 41 b communicate with each other via the outflow groove 47.

  A cylindrical guide wall 42 extending downward is integrally provided on the outer peripheral edge of the tray body 41. 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 tray member 40 is movable up and down along the inner peripheral surface of the U-shaped portion 5a. In other words, it can move up and down. 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.

  As shown in FIG. 2, the upper end of the piston guide 11 is engaged between a support wall 45 provided on the lower surface of the tray body 41 and the engaging portion 44. With such a configuration, the saucer body 41 of the saucer member 40 can be moved downward from the raised position shown in FIG. 2 to the lowered position shown in FIG. 3 by pushing down the saucer body 41 downward. At this time, a pressing force applied to the tray body 41 is transmitted to the piston guide 11.

  As shown in FIG. 1, a cap C that covers the tray member 40 and the sheet member 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, the piston mechanism 11 is actuated by operating the pump mechanism A by pushing down the saucer body 41 downward from the normal state where the saucer member 40 is in the raised position. By the operation of the pump mechanism A by the piston guide 11, the cylinder 10 and the piston 21, the contents stored in the storage space 7 of the container body 2 can be discharged onto the tray surface 41 a of the tray body 41.

  First, when the tray body 41 is pushed down by a user or the like, the pushing force acts on the tray body 41. The tray body 41 is shown in FIGS. 1 and 2 against the elastic force of the biasing member 15. It is pushed down from the raised position to the lowered position shown in FIG. At this time, the piston guide 11 is lowered together with the tray body 41, and the operation of the pump mechanism A is started.

  That is, since the check valve 20 is closed in the normal state at the raised position, when the piston guide 11 is lowered and the operation of the pump mechanism A is started, the inside of the pressurizing chamber 12 is moved to the piston guide 11. And the piston 21 mounted on the piston guide 11 moves upward to open the inflow hole 11c. When the piston guide 11 is further lowered, the pressurized content inside the pressurizing chamber 12 is supplied from the inflow hole 11c to the inflow chamber 13 inside the piston guide 11, and is directed from the discharge hole 41b toward the tray surface 41a. Discharged. The contents L discharged from the discharge hole 41b reach the gap S between the sheet member 30 and the tray surface 41a through the outflow groove 47 provided in the fixed portion 46, and further the inside of the gap S from the inner peripheral side to the outer periphery Then, the outer peripheral end of the sheet member 30 is pushed upward and discharged from the ring-shaped discharge port 48 onto the tray surface 41a. At this time, the contents L can be discharged in a ring shape around the discharge port 48.

  The contents L discharged in a ring shape on the saucer surface 41a can be used, for example, by directly scooping with a hand, or can be used by wiping with a sponge, puff or the like (hereinafter referred to as a sponge or the like). In the case of wiping the contents L with a sponge or the like, the contents discharged from the ring-shaped discharge port 48 can be reduced by pressing down the tray body 41 by pressing the sponge or the like toward the tray surface 41a. The contents can be easily taken out by adhering to a sponge or the like easily.

  When the pressing operation of the tray body 41 is released, the piston guide 11 moves upward toward the initial raised 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 lying 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 operated efficiently by operating the pump mechanism A by the push-down operation of the tray body 41. Can be discharged efficiently.

  When the content discharge operation is completed, the discharge port 48 is closed by the sheet member 30. Thus, in the pump container 1 with a saucer of the present invention, in the normal state, the discharge port 48 is reliably closed by the sheet member 30, and the saucer body 41 is pushed down to discharge the contents. Since the discharge port 48 is sometimes opened, air can be prevented from flowing from the discharge port 48 when not in use, and the contents can be accommodated without touching the air. 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.

  FIG. 5 is an enlarged cross-sectional view showing a main part of a pump container with a saucer as a second embodiment of the present invention, and FIG. 6 is an enlarged cross-sectional view of a pump container with a saucer showing a modification of FIG. In FIGS. 5 and 6, members corresponding to those described above are denoted by the same reference numerals.

  The pump container 1 with a saucer shown in the second embodiment is different from the pump container 1 with a saucer shown in the first embodiment described above mainly in a mechanism for fixing the seat member 30 and other configurations. Since the effects are the same as those of the first embodiment, differences from the first embodiment will be mainly described below.

As shown in FIG. 5, in the pump container 1 with a saucer shown in 2nd Embodiment, the fixing | fixed part 46 provided in the said 1st Embodiment is provided in the position of the upper surface center of the saucer member 40. As shown in FIG. Instead, a holding member 50 is provided.
The holding member 50 has a disc-like holding portion 51 at the top, and a support column 52 is suspended from the center of the lower surface of the holding portion 51. A plurality of convex portions 53 projecting in the outer peripheral direction are radially arranged on the lower surface of the holding portion 51 and around the base end of the support portion 52, and the lower end of the support portion 52 bulges in the outer diameter direction. A portion 54 is formed.

On the other hand, the inner diameter of the upper part and the lower part of the discharge hole 41b drilled in the center of the tray member 40 is formed with a larger diameter, and the inner diameter of the intermediate part is formed with a smaller diameter than the upper part and the lower part. A plurality of prescribed abutting portions 41c that abut on the outer circumferential surface of the column portion 52 inserted into the ejection hole 41b and regulate the radial position on the inner circumferential surface of the discharge port 41b of the intermediate portion formed the narrowest. Are projecting radially. A plurality of stepped contact support portions that support the holding member 50 by contacting the lower end of the projection 53 of the support column 52 on the inner peripheral surface of the upper discharge hole 41b formed with the largest diameter. 41d is formed radially.
Further, a bulging portion 54 of the holding portion 51 is inserted in the lower portion of the discharge hole 41b formed with a large diameter so as to prevent the holding portion 51 from coming off from inside the discharge hole 41b.

  The space formed between the prescribed contact portion 41c arranged in the circumferential direction and the outer peripheral surface of the column portion 52 and the space formed between the convex portion 53 and the prescribed contact portion 41c are both of the contents. It functions as a flow passage that can pass through. Although only one flow path is shown in FIG. 5, a plurality of flow paths are provided between the defined contact portion 41 c and the support column portion 52 and between the convex portion 53 and the defined contact portion 41 c. That is, the contents are discharged from the inflow chamber 13 to the outside of the discharge hole 41b through a plurality of flow passages formed in the circumferential direction at a portion where the discharge hole 41b and the support column 52 face each other. .

As shown in FIG. 5, in the second embodiment, the sheet member 30 is fixed to the lower surface of the holding portion 51. The sheet member 30 is also thin and circular, but the support column 52 of the holding member 50 is inserted into the insertion hole 32 formed in the center, and the inner peripheral end 33 around the insertion hole 32 is placed on the lower surface of the holding unit 51. It is fixed in close contact. Therefore, in this embodiment, the lower surface of the holding portion 51 functions as the fixing portion 46 that fixes the sheet member 30. The fixing method of the sheet member 30 is the same as that in the first embodiment. The outer peripheral end 31 side of the sheet member 30 is in a free end state that is cantilevered in the same manner as described above, and can contact the curved concave surface receiving surface 41a in a ring shape.
As shown in FIG. 5, in order to prevent the sheet member 30 from being detached from the holding portion 51, a convex portion 49 is formed in an annular shape on the saucer surface 41a facing the holding portion 51, or a dot-like convex shape. It is good also as a structure which forms the part 49 intermittently in the circumferential direction.

  Next, in the modification shown in FIG. 6, the holding member 50 is a disc-shaped holding part 51, a support part 52 that is suspended from the lower surface thereof, and a bulging part that protrudes radially from the lower end of the support part 52. 54. A discharge hole 41b is formed in the center of the tray member 40. A plurality of vertical grooves 41e forming a flow passage are intermittently formed in the circumferential direction on the inner peripheral surface of the discharge hole 41b. Further, a fixing portion 46 is formed on the upper surface of the discharge hole 41b, and outflow grooves (flow passages) 47 continuing to the vertical groove 41e are also formed radially on the fixing portion 46. In FIG. 6, only one vertical groove 41 e and outflow groove 47 are shown as the flow path, but a plurality of vertical grooves 41 e constituting the flow path are formed on the inner peripheral surface of the discharge hole 41 b and the surface of the fixing portion 46. An outflow groove 47 is provided.

  In the same manner as described above, the inner peripheral end 33 of the sheet member 30 is fixed between the lower surface of the holding portion 51 and the fixing portion 46. As for the fixing method of the sheet member 30, it may be fixed by means such as an adhesive or heat welding as described above. Alternatively, as shown by a one-dot chain line in FIG. 6, after the upper end of the column part 52 that was initially cylindrical is inserted from the lower side of the discharge hole 41 b, the upper end of the column part 52 protruding above the discharge hole 41 b is heated. However, the disk-shaped holding part 51 can be formed by crushing in a flat shape.
