Description

  The present invention relates to a discharge container.

2. Description of the Related Art Conventionally, there has been known a discharge container provided with a cover for preventing an unintended rotation operation of a pressing head located at a lower end position.
For example, a discharge container disclosed in Patent Literature 1 below has a container main body in which contents are stored, a mounting cap mounted on a mouth of the container main body, and a stem, and is inserted into the mouth of the container main body. It has a cylinder that is held by a mounting cap in a state, a stem insertion cylinder that is mounted on the upper end of the cylinder and has a stem inserted inside, and a nozzle cylinder with a discharge hole opened at the tip, and is mounted on the upper end of the stem A press head that is screwed to the stem insertion tube at the lower end position, and a cylindrical cover body that surrounds the opening of the container body, the mounting cap, and the press head from outside.

  The cover body has a vertically long window hole through which the nozzle tube is inserted, and a fitting hole into which the engaging projection formed at the mouth of the container body is fitted. Further, a removal band is connected to the cover via a breakable weakening portion.

According to the discharge container configured as described above, since the cover body surrounds the pressing head from the outside, the pressing head located at the descending end position unexpectedly rotates, for example, during distribution of the product or when not in use. Operation can be prevented. This prevents the screwing of the pressing head from being unintentionally released from the stem insertion tube.
In addition, by removing the removal band from the cover body while tearing the weakened portion, the cover body can be removed from the pressing head, and the discharge container can be used.

However, in the above-mentioned conventional discharge container, assembling of the discharge container including the cover body was easily troublesome. When assembling, a previously assembled unit is attached via a mounting cap to the container body filled with the contents, with the pressing head screwed into the stem insertion tube. Then, the cover body is mounted so as to cover the pressing head while passing the nozzle tube through the window hole, and the cover body is attached by engaging the engaging projection on the container body side in the fitting hole.
As described above, it is necessary to perform the attaching work of the cover body by itself at the end, and after covering the cover body once on the pressing head while avoiding the interference with the nozzle cylinder, the engaging projection into the fitting hole is formed. It is necessary to perform the engagement, and a complicated operation is required to attach the cover body. Therefore, it took time and effort to assemble the discharge container, and the number of assembling steps was easily increased.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a discharge container provided with a cover body having excellent assembling workability.

In order to achieve the above object, the present invention provides the following means.
(1) A discharge container according to the present invention is capable of moving downward in an upwardly biased state inside a container main body in which contents are accommodated, a mounting cap mounted on an opening of the container main body, and the mounting cap. A pump having a stem inserted into the stem, a press head mounted on the upper end of the stem and having a discharge hole for discharging the contents, a cover body covering the press head, and a lower end position. A restricting cylinder to which the pressing head is screwed and restricts the upward movement of the pressing head and the stem, wherein the pressing head comprises a lower head cylinder screwed to the restricting cylinder, and the discharge hole. And an upper head cylinder fitted to the lower head cylinder from above and fitted with the cover body, wherein the cover body moves the pressing head and the regulating cylinder in a radial direction. Surround from outside And a cover cylinder having a breakable first weakening portion formed therein, wherein the cover cylinder is capable of being divided in a circumferential direction by breaking the first weakening portion, and the cover cylinder and the regulating cylinder include: A detent portion that engages with each other and regulates relative rotation of the cover cylinder and the regulation cylinder is formed separately.

  According to the discharge container according to the present invention, when the pressing head is located at the lower end position, the relative rotation of the cover cylinder and the restricting cylinder can be regulated by the rotation preventing portion. Can be prevented from being unexpectedly rotated. Therefore, it is possible to prevent the pressing head from rotating in the loosening direction with respect to the restricting cylinder, for example, when the product is distributed or not in use, so that the screwing of the pressing head to the restricting cylinder is unintentionally released. Can be.

  In particular, the pressing head is configured by integrally combining a lower head cylinder screwed into the regulating cylinder and an upper head fitted to the lower head cylinder from above. Therefore, for example, in a state where the cover body is attached to the upper head cylinder, the upper head cylinder and the cover body are pressed down integrally with the lower head cylinder screwed to the regulating cylinder by stoppering or the like, thereby lowering the lower head cylinder. The fitting of the cylinder and the upper head cylinder and the engagement of the rotation stoppers of the cover cylinder and the regulating cylinder can be performed simultaneously. Thereby, the assembling work of the pressing head and the attaching work of the cover body can be performed simultaneously. Therefore, an increase in the number of assembling steps can be suppressed, and a discharge container excellent in assembling workability can be obtained.

  When the discharge container is used, the cover cylinder can be divided in the circumferential direction by breaking the first weakened portion, so that the cover body can be easily removed from the pressing head. Thus, the pressing head can be rotated in the loosening direction with respect to the restricting cylinder, the screwing of the pressing head to the restricting cylinder can be released, and the pressing head can be moved from the lower end position to the upper end position. As a result, the pressing head can be shifted to a state where the pressing head can be pressed down, and the content can be discharged.

(2) The cover tube may be provided with a locking portion that is locked to the restriction tube and restricts upward movement of the cover cylinder with respect to the restriction tube.

  In this case, not only the cover body is prevented from rotating with respect to the regulating cylinder by the rotation preventing part, but also the upward movement of the cover body with respect to the regulating cylinder can be regulated by the locking part. Therefore, even if a rotational force such that the pressing head rotates in the loosening direction with respect to the restricting cylinder acts on the cover body, the upward movement of the cover body due to the loosening of the pressing head can be restricted. It is possible to effectively prevent the head from being loosened or released.

(3) The first weakening portion is formed at intervals in the circumferential direction on the cover cylinder, and a portion of the cover cylinder located between the first weakening portions adjacent to each other in the circumferential direction includes: The removal piece may be a removable piece, and the removal piece may be formed over the entire length of the cover cylinder in the vertical direction.

  In this case, the cover piece can be divided sufficiently widely in the circumferential direction by removing the removal piece while tearing the first weakened portion while breaking the first weakened portion. Therefore, the cover body can be easily removed from the press head, and the work of removing the cover body can be easily performed.

(4) The cover cylinder is disposed below the main cover cylinder surrounding the pressing head from the radial outside and the main cover cylinder via a breakable second weakening portion. An auxiliary cover cylinder that is separably connected and surrounds the regulation cylinder from the outside in the radial direction, and the detent portion may be formed in the auxiliary cover cylinder.

  In this case, when the pressing head is located at the lower end position and a large rotational force is applied to the cover body, for example, to rotate the pressing head in a loosening direction, the rotation is restricted by the detent portion. Since the main cover cylinder tries to rotate relatively to the auxiliary cover cylinder, a stress based on the rotational force acts on the second weakened part, and the second weakened part is broken. Thus, it is possible to easily determine visually whether the screwing of the pressing head to the regulating cylinder is loosened or released based on the broken state of the second weakened portion.

  Further, since the main cover cylinder and the auxiliary cover cylinder are separated by the fracture of the second weakened part, the relative position of the main cover cylinder and the auxiliary cover cylinder in the vertical direction, for example, is broken by the second weakened part. It is possible to make it different from the state before being performed. Therefore, based on the change of the relative vertical positional relationship between the main cover cylinder and the auxiliary cover cylinder, it is easier to visually recognize whether or not the screwing of the pressing head to the regulating cylinder is loosened or released. Is easy to determine.

(5) The cover may include a lid that covers the pressing head from above over the entire area.

  In this case, the pressing head can be protected by using the cover body, and the pressing head cannot be touched unless the cover body is removed. It is easier to keep clean. Further, it is possible to prevent the pressing head alone from being operated unintentionally before removing the cover body.

(6) On the inner peripheral surface of the mounting cap, a plurality of claw portions for regulating rotation of the mounting cap in the loosening direction with respect to the mouth of the container body are formed at intervals in the circumferential direction, and the mounting cap is formed. Of the above, a thin portion in which the thickness of the mounting cap is thinner than other portions may be formed in a portion adjacent to the claw portion in the circumferential direction.

In this case, when the pressing head is located at the descending end position, for example, a rotational force that rotates the mounting cap in the loosening direction with respect to the opening of the container body while the cover body is attached. Even if acts on the mounting cap, the claw restricts the rotation of the mounting cap in the loosening direction. Therefore, it is possible to prevent the mounting cap from being loosened or removed, for example, when the product is distributed or not used.
In particular, when a rotational force is applied to rotate the mounting cap in the loosening direction, a stress against the rotational force acts on the thin-walled portion via the claw portion, so that the thin-walled portion is likely to be broken or elongated. Therefore, based on the change in the state of the thin portion, it can be visually determined whether or not a rotational force has been applied to the mounting cap in the loosening direction.

  ADVANTAGE OF THE INVENTION According to this invention, the increase in the number of assembly steps can be suppressed and it can be set as the discharge container excellent in assembling workability.

(1st Embodiment)
Hereinafter, a first embodiment of a discharge container according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, a discharge container 1 according to the present embodiment has a cylindrical container body 2 having a bottom and containing a content, and a cylindrical mounting cap mounted on an opening 12 of the container body 2. 3, a pump 5 having a stem 4 inserted downwardly movably in an upwardly biased state inside the mounting cap 3, and a discharge hole 6 mounted on the upper end of the stem 4 and discharging the contents. It has a pressing head 7 formed and a cover 8 covering the pressing head 7.

  In a stage such as when not in use, the stem 4 and the pressing head 7 are located at the descending end position P1 as shown in FIG. 1, and the pressing head 7 is held by screwing on a regulating cylinder 31 described later. And the upward movement is restricted. On the other hand, in the use stage, the pressing head 7 is located at the rising end position P2 together with the stem 4, and shifts to a standby state for pressing.

  In addition, the container main body 2, the mounting cap 3, and the stem 4 are disposed with their respective central axes located on a common axis. In the present embodiment, the common axis is referred to as a container axis O, and the pressing head 7 side along the container axis O is referred to as an upper side, and the bottom side of the container main body 2 is referred to as a lower side. Further, in a plan view as viewed from the container axis O direction, a direction orthogonal to the container axis O is referred to as a radial direction, and a direction orbiting around the container axis O is referred to as a circumferential direction. Further, among the circumferential directions, a direction in which the container axis O rotates clockwise in a top view of the discharge container 1 is referred to as a first direction M1, and the opposite side is referred to as a second direction M2.

The container main body 2 is formed in a bottomed cylindrical shape having a bottom portion (not shown), a body portion 10, a shoulder portion 11, and a mouth portion 12. In the illustrated example, the upper end portion of the body portion 10 is formed so as to gradually increase in diameter toward the connection portion with the shoulder portion 11, and the shoulder portion 11 is formed so as to project radially outward.
However, the shape of the container body 2 is not limited to this case. In addition, the shape of the body 10 may be, for example, a circular shape, an elliptical shape, or a polygonal shape in a cross-sectional view, and is not limited to a specific shape.

  A first screw portion 13 to which the mounting cap 3 is screwed is formed on the outer peripheral surface of the mouth portion 12. The first screw portion 13 is formed in a helical shape so that the mounting cap 3 is tightened when the mounting cap 3 is relatively rotated with respect to the container body 2 in the first direction M1. Therefore, the second direction M2 is a loosening direction of the mounting cap 3.

A plurality of first locking projections 14 projecting radially outward are formed on the outer peripheral surface at the lower end of the mouth 12 at intervals in the circumferential direction.
As shown in FIG. 4, the first locking projection 14 is formed such that the circumferential length along the circumferential direction is longer than the radially outward protruding amount from the outer peripheral surface of the mouth portion 12. A first peripheral end face of the first locking projection 14 located on the first direction M1 side is a vertical locking surface 14a. On the other hand, the second peripheral end face of the first locking projection 14 located on the second direction M2 side is an inclined surface 14b that gradually extends radially outward in the first direction M1.

  As shown in FIG. 1, the pump 5 is held by the mounting cap 3 in a state in which the stem 4 is inserted into the mouth portion 12 of the container body 2, and the cylinder 20 in which the stem 4 is erected upward. And a piston (not shown) linked to the stem 4 and fitted in the cylinder 20 so as to be vertically slidable.

The cylinder 20 is arranged coaxially with the container axis O, and is formed in a multi-stage cylindrical shape whose diameter is reduced stepwise from above to below.
At the upper end of the cylinder 20, a flange portion 21 protruding radially outward is formed in an annular shape over the entire circumference of the cylinder 20. The flange portion 21 is disposed on the upper end opening edge of the mouth portion 12 of the container body 2 via a packing 22. As a result, the cylinder 20 is supported while being inserted into the mouth 12 of the container body 2.

  Further, the cylinder 20 has a protruding cylindrical portion 23 extending upward from the inner peripheral edge of the flange portion 21 and formed coaxially with the container axis O, and has a container main body at a portion located below the flange portion 21. An air hole 24 communicating between the inside of the cylinder 2 and the inside of the cylinder 20 is formed. At the lower end of the cylinder 20, a suction cylinder 25 extending downward is formed simultaneously with the container axis O. A tube body 26 for sucking up the contents is fitted in the suction tube portion 25.

  A valve member (not shown) for opening and closing the lower end opening of the cylinder 20 and a coil spring (biasing means) for biasing the stem 4 upward are provided in the cylinder 20.

  The valve member is arranged so as to be located above the tube body 26. The valve member is a check valve that keeps the lower end opening of the cylinder 20 closed when the cylinder 20 is pressurized and opens the lower end opening of the cylinder 20 when the cylinder 20 is depressurized. This restricts the contents inside the cylinder 20 from returning to the inside of the container body 2 through the lower end opening of the cylinder 20 when the cylinder 20 is pressurized, and the contents inside the container body 2 when the cylinder 20 is depressurized. Is allowed to flow into the cylinder 20 through the lower end opening of the cylinder 20.

  The piston is in close sliding contact with the inner peripheral surface of the cylinder 20 and moves up and down in the cylinder 20 with the stem 4. The above-described coil spring is disposed, for example, between the piston and the valve member, and urges the stem 4 upward through the piston. An annular space defined between the stem 4 and the cylinder 20 and communicating with the air hole 24 is formed on the stem 4 in the cylinder 20.

Further, the pump 5 of the present embodiment has a pressing cylinder 7 which is screwed with the pressing head 7 located at the descending end position P1, and a regulating cylinder 31 which regulates the upward movement of the pushing head 7 and the stem 4 located at the descending end position P1; A seal cylinder 32 for closing the air hole 24 of the cylinder 20 when the head 7 is located at the lower end position P1.
However, the present invention is not limited to this case, and the mounting cap 3 may be configured to include the regulating cylinder 31 and the sealing cylinder 32, and the regulating cylinder 31 is configured separately from the mounting cap 3 and the pump 5. It does not matter.

After the mounting cap 3 is described first, the regulating cylinder 31 and the sealing cylinder 32 will be described.
The mounting cap 3 has an upper cylindrical portion 35, a lower cylindrical portion 36 connected to a lower end of the upper cylindrical portion 35, and an annular top wall portion 37 connected to an upper end of the upper cylindrical portion 35. It is formed in a tubular shape.

The upper cylinder 35 and the lower cylinder 36 surround the mouth 12 of the container body 2 from the radial outside. The lower cylindrical portion 36 is formed to have a larger diameter than the upper cylindrical portion 35, and surrounds the first locking projection 14 formed on the mouth 12 side of the container body 2 from the radial outside.
On the inner peripheral surface of the upper cylindrical portion 35, a second screw portion 38 which is screwed to the first screw portion 13 formed in the mouth portion 12 of the container body 2 is formed.

  The top wall portion 37 is disposed on the flange portion 21 of the cylinder 20. As a result, the cylinder 20 is held by the mounting cap 3 and is prevented from dropping upward. The protruding cylindrical portion 23 of the cylinder 20 is inserted inside the top wall portion 37.

On the inner peripheral surface of the lower cylindrical portion 36, a second locking projection (claw portion) 39 for restricting rotation of the mounting cap 3 in the second direction (loosening direction) M2 with respect to the mouth portion 12 of the container body 2 is formed. ing.
As shown in FIGS. 1 and 4, the second locking projection 39 protrudes radially inward from the inner peripheral surface of the lower cylindrical portion 36 and is formed in a vertically long plate-like shape along the container axis O. , Are formed at intervals in the circumferential direction.

The second locking projection 39 is formed so as to gradually extend in two directions M2 as it goes radially inward from the inner peripheral surface of the lower cylindrical portion 36. For this reason, the second locking projection 39 is formed to project obliquely so as to be inclined corresponding to the inclined surface 14 b of the first locking projection 14.
As a result, the second locking projection 39 is slid on the inclined surface 14b with the rotation of the mounting cap 3 in the first direction M1 with respect to the mouth portion 12 of the container body 2 while sliding. 14 in the circumferential direction. Therefore, the mounting cap 3 can be screwed into the mouth portion 12 of the container body 2 in the first direction M1.

  On the other hand, when the mounting cap 3 is rotated in the second direction M <b> 2 with respect to the mouth 12 of the container body 2, the inner end of the second locking projection 39 locks the first locking projection 14. It is locked from the circumferential direction on the surface 14a. Thereby, rotation of the mounting cap 3 in the second direction M2 is restricted.

In the illustrated example, the interval between the second locking projections 39 in the circumferential direction is slightly smaller than the interval between the first locking projections 14 in the circumferential direction (narrow pitch). Thereby, as shown in FIG. 4, for example, when one second locking projection 39 is locked on the locking surface 14a of the first locking projection 14, the other second locking projection 39 , Can be kept in a state of being separated from the locking surface 14 a of the first locking projection 14 in the circumferential direction.
Accordingly, when a rotational force that rotates the mounting cap 3 in the second direction M2 acts on the mounting cap 3, the second locking projection 39 locked on the locking surface 14a temporarily becomes the first locking projection. Even if it is attempted to cross over the second locking projection 14 in the second direction M2, the second locking projection 39 adjacent in the circumferential direction is immediately locked to the locking surface 14a of the first locking projection 14 adjacent in the circumferential direction. .
Therefore, by setting the circumferential interval of the second locking projection 39 to be slightly smaller than the circumferential interval of the first locking projection 14, the rotation of the mounting cap 3 in the second direction M2 is effective. It is possible to regulate it.
However, the present invention is not limited to this case. For example, the circumferential spacing of the second locking projections 39 may be made to match the circumferential spacing of the first locking projections 14.

As described above, the first locking projection 14 and the second locking projection 39 allow the mounting cap 3 to rotate in the tightening direction (first direction M1) with respect to the mouth portion 12 of the container main body 2, and It functions as a ratchet mechanism that regulates rotation of the mounting cap 3 in the loosening direction (second direction M2) with respect to the mouth portion 12 of the main body 2.
The second locking projections 39 may be formed in the same number as the first locking projections 14, or may be formed in different numbers.

Further, a thin portion 40 in which the thickness of the lower cylinder portion 36 is thinner than other portions is formed in a portion of the lower cylinder portion 36 adjacent to the second locking projection 39 in the circumferential direction.
Specifically, the thin portion 40 is formed thin by a vertical groove 41 formed on the inner peripheral surface of the lower cylindrical portion 36. The vertical groove 41 is formed in a portion of the inner peripheral surface of the lower cylindrical portion 36 adjacent to the second locking projection 39 on the first direction M1 side.

  As shown in FIGS. 1 and 5, the regulating cylinder 31 has an outer cylinder 50 fitted (for example, undercut-fit) to the projecting cylinder 23 of the cylinder 20 and an inner cylinder 50 arranged inside the projection cylinder 23. A tube 51, an outer tube 52 surrounding the outer tube 50 from the outside in the radial direction, an upper end of the outer tube 52 and an upper end of the outer tube 50 are radially connected, and the inner end is connected to the inner tube 51. Annular connecting plate 53.

  The inner cylinder 51 is formed so as to protrude above the protruding cylinder 23, and the lower end thereof is fitted inside the upper end of the cylinder 20. On the outer peripheral surface of a portion of the outer peripheral surface of the inner cylinder 51 located below the connecting plate 53, and on the inner peripheral surface of the protruding cylindrical portion 23, vertically long detent ribs 54 and 55 which engage with each other in the circumferential direction are provided. Are formed separately.

  A third screw portion 56 to which the pressing head 7 located at the lower end position P1 is screwed is formed in a portion of the outer peripheral surface of the inner cylinder 51 located above the connecting plate 53. The third screw portion 56 is formed in a spiral shape so that the pressing head 7 is tightened when the pressing head 7 is relatively rotated in the first direction M1 with respect to the regulating cylinder 31.

  The outer shell 52 is formed in a cylindrical shape having a smaller diameter than the upper cylindrical part 35 of the mounting cap 3, and has a length that does not reach the top wall 37 of the mounting cap 3 from the outer peripheral edge of the connecting plate 53. And extends downward. Thereby, a gap is secured between the lower edge of the outer cylinder 52 and the top wall 37 in the container axis O direction.

  A plurality of vertically elongated first restricting pieces (rotation preventing portions) 59 protruding radially outward and extending along the container axis O are formed on the outer peripheral surface of the outer cylinder 52 at intervals in the circumferential direction. Have been. In the illustrated example, the first restriction pieces 59 are formed so as to be arranged at a narrow pitch in the circumferential direction so as to perform knurling on the outer peripheral surface of the outer casing 52. However, the space between the first regulating pieces 59 adjacent in the circumferential direction may be freely designed.

The seal cylinder 32 is provided inside the inner cylinder 51 of the restriction cylinder 31. At the lower end of the seal cylinder 32, a not-shown closed cylinder part slidably fitted in the cylinder 20 is formed.
The closing cylinder part closes the air hole 24 when the pressing head 7 and the stem 4 are located at the lower end position P1 and the pressing head 7 is screwed into the regulating cylinder 31. When the pressing head 7 and the stem 4 are located at the rising end position P2, for example, the closing cylinder is pushed up from below by a piston to open the air hole 24.

  The stem 4 is disposed inside the seal cylinder 32 so as to be able to move up and down. In addition, an annular communication path is formed between the outer peripheral surface of the stem 4 and the inner peripheral surface of the seal cylinder 32 to communicate the outside with the above-described annular space. Note that the seal cylinder 32 is not essential and does not have to be provided.

  As shown in FIG. 1, the pressing head 7 includes a lower head cylinder 60 screwed to the regulating cylinder 31 and an upper head to which the lower head cylinder 60 is fitted from above and the cover body 8 is mounted. The lower head cylinder 60 and the upper head cylinder 61 are integrally combined.

  The lower head cylinder 60 includes a screwing cylinder 62 screwed to the inner cylinder 51 of the regulating cylinder 31, an outer connecting cylinder 63 surrounding the screwing cylinder 62 from the outside in the radial direction, and a position higher than the upper end of the stem 4. , An upper end portion of the screwed tube 62, an upper end portion of the outer connection tube 63, and an annular top wall plate 65 which integrally connects the inner connection tube 64 in the radial direction, and an inner connection tube And a fitting cylinder 67 that is connected to the lower end of the stem 64 via a stepped portion 66 and that is fitted inside the upper end of the stem 4.

A fourth screw portion 68 that is screwed to the third screw portion 56 formed on the inner cylinder 51 of the regulating cylinder 31 is formed on the inner peripheral surface of the screw cylinder 62. The pressing head 7 and the stem 4 are held at the lower end position P1 by the screwing of the fourth screw portion 68 to the third screw portion 56, and the upward movement is restricted.
When the lower end of the screwing cylinder 62 comes into contact with the connecting plate 53 of the regulating cylinder 31 from above, the tightening of the pressing head 7 with respect to the regulating cylinder 31 is completed.

The outer connecting cylinder 63 is formed to have the same diameter as the outer cylinder 52 of the regulating cylinder 31. The inner connecting cylinder 64 is formed to have the same diameter as the seal cylinder 32, and protrudes above the top wall plate 65. The fitting tube 67 is formed to have a smaller diameter than the inner connection tube 64, and is fitted inside the stem 4 from above. By the fitting of the stem 4 and the fitting cylinder 67, the pressing head 7 is mounted on the upper end of the stem 4 and is integrally combined.
The upper end opening edge of the stem 4 is in contact with the stepped portion 66 from below. When the pressing head 7 is located at the lower end position P1, the seal cylinder 32 is pushed down from above by the stepped portion 66.

  The upper head cylinder 61 surrounds the outer connecting cylinder 63 from the outside in the radial direction, and has an outer fitting cylinder 70 externally fitted to the outer connecting cylinder 63 and a circular shape in a plan view that closes an upper end of the outer fitting cylinder 70. And a connection tube 72 extending downward from a central portion of the top wall portion 71 and fitted into the inside of the inner connection tube 64 from above. .

As shown in FIGS. 1 and 2, the outer fitting cylinder 70 is formed with a discharge nozzle 73 that protrudes radially outward and has a discharge hole 6 formed at the end thereof.
In the illustrated example, the discharge nozzle 73 is formed so that the circumferential width along the circumferential direction becomes gradually smaller toward the outside in the radial direction. Further, the discharge nozzle 73 is formed so as to be integral with the top wall portion 71, and extends inside the outer casing 52 and is integrally connected to the connection cylinder 72. Thus, the inside of the discharge nozzle 73 communicates with the inside of the connection cylinder 72. However, the shape of the discharge nozzle 73 is not limited to the case described above.

  The connection cylinder 72 is formed such that the inner diameter is the same as the inner diameter of the inner connection cylinder 64, and the lower opening edge is in contact with the stepped portion 66 from above.

The cover cylinder 80 is provided so as to be able to be divided in the circumferential direction, and is mounted so as to cover mainly the upper head cylinder 61.

  The cover cylinder 80 is disposed below the main cover cylinder 82 and surrounds the pressing head 7 from the radial outside, and is integrally connected to the main cover cylinder 82 so as to connect the regulating cylinder 31 to the radial outside. And an auxiliary cover cylinder 83 that surrounds the cover.

  The main cover cylinder 82 is formed along the outer shape of the outer fitting cylinder 70 and the discharge nozzle 73 so as to surround the outer fitting cylinder 70 and the discharge nozzle 73 of the upper head cylinder 61 from the outside in the radial direction. Further, the main cover cylinder 82 is integrally formed with a lid cover 84 that covers a portion of the discharge nozzle 73 located on the tip end side from above.

The auxiliary cover cylinder 83 is formed to have a smaller diameter than the main cover cylinder 82, and is integrally connected to a lower end of the main cover cylinder 82.
As shown in FIG. 5, the lower opening edge of the auxiliary cover cylinder 83 is in contact with the top wall 37 of the mounting cap 3 from above. As a result, the lower end of the auxiliary cover tube 83 protrudes below the lower end of the outer tube 52 of the regulating tube 31. On the inner peripheral surface of the lower end portion of the auxiliary cover cylinder 83, a locking claw (locking portion) 85 that is locked to the regulating cylinder 31 and regulates the upward movement of the cover cylinder 80 relative to the regulating cylinder 31 is formed. I have.

In the illustrated example, the locking claw 85 is formed so as to protrude radially inward from the inner peripheral surface of the lower end portion of the auxiliary cover cylinder 83, and to extend gradually upward toward the radially inner side. The lower end opening of the cylinder 52 is locked from below. A plurality of locking claws 85 are formed at intervals in the circumferential direction.
However, the locking claw 85 may be formed in an annular shape over the entire circumference of the auxiliary cover cylinder 83.

  As described above, the auxiliary cover cylinder 83 comes into contact with the top wall portion 71 of the mounting cap 3 from above, and the locking claw 85 is locked from below on the lower end opening edge of the outer casing 52, The cover body 8 is mounted on the upper head cylinder 61 while being positioned in the container axis O direction.

  On the inner peripheral surface of the auxiliary cover cylinder 83, a second restriction piece (rotation stop portion) 86 is formed to fit from the circumferential direction with the first restriction piece 59 formed on the outer cylinder 52 of the restriction cylinder 31. I have. The second restricting piece 86 protrudes radially inward from the inner peripheral surface of the auxiliary cover cylinder 83 and is formed in a vertically elongated shape extending along the container axis O. In the illustrated example, the second restriction pieces 86 are formed at intervals in the circumferential direction, and are arranged so as not to overlap with the locking claws 85 in the container axis O direction. However, the second restriction piece 86 may be formed so as to be disposed above the locking claw 85. In this case, for example, a through hole or the like may be formed in the locking claw 85 to pass a molding die when the second regulating piece 86 is molded.

  As described above, the relative rotation of the cover cylinder 80 and the restriction cylinder 31 is restricted by the first restriction piece 59 and the second restriction piece 86 being fitted to each other in the circumferential direction.

As shown in FIG. 3, the first weakened portions 81 are formed at intervals along the up-down direction of the cover cylinder 80 and are formed at intervals in the circumferential direction. The portion of the cover cylinder 80 located between the first weakening portions 81 adjacent to each other in the circumferential direction is a removable piece 87 that can be removed.
In the illustrated example, the removal piece 87 is disposed on the opposite side in the radial direction with respect to the discharge nozzle 73 across the container axis O, and extends over the entire length of the cover cylinder 80 in the vertical direction (the main cover cylinder 82 and the (Over the auxiliary cover cylinder 83).

  The first weakening portion 81 is not limited to the above-described case, and may be, for example, a weakening line in which a thin portion is continuously formed in a belt shape in the vertical direction.

(Operation of the discharge container)
Next, the operation of the discharge container 1 configured as described above will be described. First, the case of assembling the discharge container 1 will be briefly described.
In this case, first, the mounting cap 3, the pump 5, the pressing head 7, and the cover body 8 are integrally combined.
Specifically, the fitting barrel 67 of the lower head barrel 60 is fitted to the upper end of the stem 4, and the lower head barrel 60 is mounted on the stem 4. Next, while moving the lower head cylinder 60 downward so as to push down the stem 4, the lower head cylinder 60 is rotated in the first direction M <b> 1 with respect to the inner cylinder 51 of the regulating cylinder 31, and the fourth screw portion 68 is rotated. Is screwed onto the third screw portion 56. Thus, the lower head cylinder 60 is held at the lower end position P1.

  Next, for example, in a state where the cover body 8 is attached to the upper head cylinder 61, the upper head cylinder 61 and the cover body 8 are pressed down integrally with the lower head cylinder 60 screwed to the regulating cylinder 31 by tapping or the like. . Thereby, the fitting of the lower head cylinder 60 and the upper head cylinder 61, the fitting of the first restriction piece 59 and the second restriction piece 86, and the locking of the locking claw 85 to the outer casing 52 are simultaneously performed. be able to. Thereby, the assembling operation of the pressing head 7 and the mounting operation of the cover body 8 can be performed simultaneously by one pressing operation.

As described above, it is possible to obtain a unit in which the mounting cap 3, the pump 5, the pressing head 7, and the cover body are integrally combined.
Next, after filling the contents into the container main body 2, the mounting unit 3 is attached to the mouth portion 12 of the container main body 2, so that the above unit is integrally combined with the container main body 2. Specifically, the mounting cap 3 is screwed to the opening 12 of the container body 2 by rotating the mounting cap 3 in the first direction L1 with respect to the opening 12 of the container body 2.

As a result, the discharge container 1 can be assembled.
In particular, since the pressing head 7 is composed of two parts, the lower head cylinder 60 and the upper head cylinder 61, the assembling operation of the pressing head 7 and the mounting operation of the cover body 8 are simultaneously performed by one pressing operation. The unit in which the cover body 8 is attached to the pressing head 7 can be assembled. Therefore, unlike the conventional assembly, there is no need to attach the cover 8 after assembling the unit to the container body 2. Therefore, an increase in the number of assembling steps after filling the contents can be suppressed, and the discharge container 1 excellent in assembling workability can be obtained.

In addition, since the assembling operation of the pressing head 7 and the attaching operation of the cover body 8 can be performed simultaneously by one pressing operation, the above-mentioned unit in which the cover body 8 is attached to the pressing head 7 can be obtained. Can be performed efficiently, and the manufacturing cost can be reduced.
Moreover, since the cover body 8 can be mounted by tapping the cover body 8 together with the upper head cylinder 61, it is possible to use an existing assembly and manufacturing apparatus. Also in this regard, it is easy to reduce the manufacturing cost.

In addition, at the time of the above-mentioned assembling, the cover body 8 was previously attached to the upper head cylinder 61, but the present invention is not limited to this case.
For example, after temporarily assembling the upper head cylinder 61 with the lower head cylinder 60 screwed to the regulating cylinder 31 and further temporarily assembling the cover body 8 with the upper head cylinder 61, the upper head cylinder 61 Alternatively, the cover body 8 may be pressed down integrally with a stopper or the like. Even in this case, the upper head cylinder 61 can be combined with the lower head cylinder 60, and the cover body 8 can be attached to the upper head cylinder 61. Therefore, the unit in which the cover body 8 is attached to the pressing head 7 can be efficiently assembled.

Next, the case where the discharge container 1 is used will be described.
As shown in FIGS. 1 and 5, when the pressing head 7 and the stem 4 are at the lower end position P <b> 1, the cover 8 is attached to the discharge container 1 of the present embodiment, and the first restricting piece 59 and the second The relative rotation of the cover body 8 and the control cylinder 31 is controlled by the control pieces 86 being fitted in the circumferential direction. Therefore, it is possible to prevent the pressing head 7 from being rotated unexpectedly via the cover body 8.

  Therefore, for example, when the product is distributed or not used, the pressing head 7 rotates in the second direction (loosening direction) M2 with respect to the regulating cylinder 31, and the pressing head 7 is not screwed onto the regulating cylinder 31 without intention. Can be prevented from being released.

  In addition, the cover body 8 is not only prevented from rotating with respect to the regulating cylinder 31 by the first regulating piece 59 and the second regulating piece 86, but also restricted from moving upward with respect to the regulating cylinder 31 by the locking claw 85. . Therefore, even if a rotational force such that the pressing head 7 rotates in the second direction M <b> 2 acts on the cover 8, the upward movement of the cover 8 due to the loosening of the pressing head 7 can be restricted. In addition, it is possible to effectively prevent the screwing of the pressing head 7 from being loosened or released from the regulating cylinder 31.

Further, when the pressing head 7 and the stem 4 are at the lower end position P1, the mounting cap 3 is rotated in the second direction M2 with respect to the opening 12 of the container body 2 while the cover body 8 is attached, for example. Even if such a rotational force acts on the mounting cap 3, as shown in FIG. 4, the second locking projection 39 locks the locking surface 14a of the first locking projection 14 from the circumferential direction. Therefore, the rotation of the mounting cap 3 in the second direction M2 is restricted.
Therefore, it is possible to prevent the mounting cap 3 from being loosened or removed.

In addition, when a rotational force is applied to rotate the mounting cap 3 in the second direction M <b> 2, a stress against the rotational force acts on the thin portion 40 via the second locking projection 39, so that the thin portion 40 is applied to the thin portion 40. For example, breakage and elongation are likely to occur. When the thin portion 40 is elongated, a whitening phenomenon appears in the thin portion 40.
Therefore, it is easy to visually determine whether or not a rotational force in the second direction M2 has acted on the mounting cap 3 based on a change in the state of the thin portion 40 (whether or not there is a break or a whitening phenomenon has occurred). Can be.

  Next, when discharging the content, the first weakened portion 81 is broken and the removal piece 87 is removed so as to tear it off. Thereby, the cover cylinder 80 can be widely divided in the circumferential direction, so that the cover body 8 can be easily removed from the pressing head 7. Thus, the pressing head 7 can be rotated in the second direction M2 with respect to the regulating cylinder 31, and the screwing of the pressing head 7 to the regulating cylinder 31 can be released.

When the screwing of the pressing head 7 is released, the stem 4 and the pressing head 7 integrally move upward by the urging force of the coil spring and move to the rising end position P2. As a result, the pressing head 7 can be shifted to a state where the pressing head 7 can be pressed down, and the content can be discharged.
Specifically, when the pressing head 7 is pressed and moved downward together with the stem 4, the piston moves downward in the cylinder 20, so that the pressure in the cylinder 20 can be increased. Thus, the contents in the cylinder 20 can be supplied into the discharge nozzle 73 and can be discharged to the outside through the discharge holes 6.

  When the pressing of the pressing head 7 is released, the stem 4 and the pressing head 7 are restored to the rising end position P2 by the urging force of the coil spring, and the pressure in the cylinder 20 becomes negative. Can be sucked into the cylinder 20. This makes it possible to prepare for the next ejection operation by the pressing head 7.

As described above, according to the discharge container 1 of the present embodiment, since the cover body 8 is prevented from rotating with respect to the regulating cylinder 31 by the first regulating piece 59 and the second regulating piece 86, the regulating cylinder It is possible to prevent the screwing of the pressing head 7 from being unintentionally loosened or released.
Further, since the pressing head 7 is composed of two parts, the upper head cylinder 61 and the lower head cylinder 60, an increase in the number of assembling steps due to the provision of the cover body 8 can be suppressed, and the assembling workability is excellent. The discharge container 1 can be used.

(2nd Embodiment)
Next, a second embodiment of the discharge container according to the present invention will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 6 and 7, in the discharge container 90 of the present embodiment, the main cover cylinder 82 and the auxiliary cover cylinder 83 are separably connected via a breakable second weakening portion 91.

The second weakening portions 91 are formed so as to connect the lower end of the main cover cylinder 82 and the upper end of the auxiliary cover cylinder 83 in the radial direction, and are formed at intervals in the circumferential direction.
In the illustrated example, the second weakening portion 91 is formed so that the thickness in the container axis O direction becomes gradually smaller from the main cover cylinder 82 toward the inside in the radial direction. Thereby, the second weakened portion 91 has a structure in which a connection portion between the second weakened portion 91 and the auxiliary cover cylinder 83 is easily broken. However, the shape of the second weakening portion 91 is not limited to this case.

  Further, the auxiliary cover cylinder 83 of the present embodiment is arranged above the top wall 71 of the mounting cap 3 with an interval. Thus, a gap is secured between the lower end opening edge of the auxiliary cover cylinder 83 and the top wall 71 in the container axis O direction.

(Operation of the discharge container)
In the discharge container 90 configured as described above, when the stem 4 and the pressing head 7 are located at the lower end position P1, for example, a rotational force for rotating the pressing head 7 in the second direction M2 is applied to the cover body 8. , The main cover cylinder 82 tends to rotate relative to the auxiliary cover cylinder 83, the rotation of which is restricted by the engagement of the first restriction piece 59 and the second restriction piece 86. The stress based on the rotational force acts on the portion 91, and the second weakened portion 91 is broken.
This makes it possible to visually determine whether or not the screwing of the pressing head 7 to the regulating cylinder 31 has been loosened or released based on the state of the second weakening portion 91 (whether or not there is a break).

Further, as the second weakened portion 91 is broken, the main cover cylinder 82 and the auxiliary cover cylinder 83 are separated in the vertical direction as shown in FIG. 8, so that the auxiliary cover cylinder 83 descends by the gap. , And comes into contact with the top wall 71 of the mounting cap 3 from above.
Accordingly, the relative vertical positional relationship between the main cover cylinder 82 and the auxiliary cover cylinder 83 can be made different from the state before the second weakened portion 91 is broken (the state shown in FIG. 7). Therefore, based on the change in the relative vertical positional relationship between the main cover cylinder 82 and the auxiliary cover cylinder 83, it is visually determined whether the screwing of the pressing head 7 to the regulating cylinder 31 has been loosened or released. It can be more easily determined.

  In this embodiment, only the upper portion of the removed piece 87 located on the main cover cylinder 82 side may be peeled off while the first weakened portion 81 and the second weakened portion 91 are broken. In this case, only the main cover cylinder 82 can be detached from the pressing head 7 while breaking the second weakened portion 91 thereafter. For example, a lower portion of the removal piece 87 located on the auxiliary cover cylinder 83 side, and It can be used with the auxiliary cover tube 83 attached.

Further, the first weakened portion 81 and the removal piece 87 may be formed only in the main cover cylinder 82.
Even in this case, by tearing off the removal piece 87 while breaking the first weakening portion 81 and the second weakening portion 91, for example, only the main cover cylinder 82 is pressed while the second weakening portion 91 is broken. Can be removed from. This allows the user to use the apparatus with the auxiliary cover tube 83 attached.
In particular, since the second weakened portion 91 is broken at a portion where the second weakened portion 91 is connected to the auxiliary cover cylinder 83, the second weakened portion 91 hardly remains on the auxiliary cover cylinder 83 side. Therefore, as shown in FIG. 8, it is possible to prevent the remaining residue of the second weakened portion 91 from remaining on the auxiliary cover cylinder 83 side, thereby improving the appearance and easily eliminating an unpleasant touch.

(Third embodiment)
Next, a third embodiment of the discharge container according to the present invention will be described. In the third embodiment, the same components as those in the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIGS. 9 and 10, in the discharge container 100 of the present embodiment, the main cover cylinder 82 projects above the top wall 71 of the upper head cylinder 61, and the lid cover 84 is positioned above the discharge nozzle 73. Are spaced apart from each other. Thereby, a gap is secured between the lid cover 84 and the discharge nozzle 73 in the container axis O direction.
The auxiliary cover tube 83 of this embodiment is in contact with the top wall 37 of the mounting cap 3 from above, as in the first embodiment.

(Operation of the discharge container)
In the discharge container 100 configured as described above, similarly to the second embodiment, based on the broken state of the second weakening portion 91, whether the screwing of the pressing head 7 to the regulating cylinder 31 is loosened or released. Can be visually identified.

  Further, the main cover cylinder 82 and the auxiliary cover cylinder 83 are separated in the up-down direction by the breakage of the second weakened portion 91, so that the main cover cylinder 82 descends by the above gap, and as shown in FIG. 11 and FIG. As shown, the lid cover 84 comes into contact with the discharge nozzle 73 from above. Therefore, the main cover cylinder 82 surrounds the auxiliary cover cylinder 83 from the outside in the radial direction, and it is difficult to visually recognize the auxiliary cover cylinder 83 from outside.

  Therefore, even in the case of the present embodiment, the relative vertical positional relationship between the main cover cylinder 82 and the auxiliary cover cylinder 83 is made different from the state before the second weakened portion 91 is broken. Can be. Therefore, based on the change in the relative vertical positional relationship between the main cover cylinder 82 and the auxiliary cover cylinder 83, it is visually determined whether the screwing of the pressing head 7 to the regulating cylinder 31 has been loosened or released. It can be more easily determined.

  In this embodiment, the first weakened portion 81 and the removal piece 87 may be formed only in the main cover cylinder 82. In this case, as in the second embodiment, only the main cover cylinder 82 can be detached from the pressing head 7 and can be used with the auxiliary cover cylinder 83 attached. In addition, since the second break portion is unlikely to remain on the auxiliary cover cylinder 83 side, the break residue of the second weakened portion 91 can be prevented from remaining, and the appearance can be improved and unpleasant touch can be easily eliminated.

  Note that the technical scope of the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention.

For example, in each of the above embodiments, the removing piece 87 is provided on the cover body 8, but the removing piece 87 is not an essential component and may not be provided.
For example, a first weakened portion 81 may be formed in the cover tube 80 along the up-down direction, and the first weakened portion 81 may be broken to divide the cover tube 80 in the circumferential direction. However, by providing the removing piece 87 as described above, the cover cylinder 80 can be divided sufficiently widely in the circumferential direction, so that the cover body 8 can be easily removed smoothly, which is preferable.

In the case where the removal piece 87 is provided, as shown in FIG. 13, for example, an L-shaped notch 110 is formed in the removal piece 87, and a part of the removal piece 87 functions as the operation piece 111. No problem.
In this case, the notch 110 allows the upper removal piece 112 formed on the main cover cylinder 82 side, the lower removal piece 113 formed on the auxiliary cover cylinder 83 side, the upper removal piece 112 and the lower removal piece 113 The removal piece 87 can be composed of the connection removal piece 114 that connects the upper and lower parts vertically and the operation piece 111 that is connected to the lower removal piece 113.

  The operation piece 111 and the connection removal piece 114 are arranged in the circumferential direction with the notch 110 therebetween. Further, the lower removal piece 113 and the connection removal piece 114 are connected via a breakable not-shown weakening portion. Therefore, the operation piece 111 is an operation member for removing the lower removal piece 113.

  When the removal piece 87 is configured in this manner, the upper removal piece 112 and the connection removal piece 114 are removed while breaking the first weakened portion 81, and then the first weakened portion 81 is broken using the operation piece 111. The lower removal piece 113 can be removed while doing so. As described above, by using the operation piece 111, stress can be applied to the lower removal piece 113 at a position closer to the lower removal piece 113, so that the entire removal piece 87 can be more easily removed more easily.

  Although FIG. 13 shows an example in which the present invention is applied to the discharge container 100 of the third embodiment, the present invention may be applied to the discharge container 1 of the first embodiment and the discharge container 90 of the second embodiment. .

Further, in the removal piece 87 shown in FIG. 13, the connection removal piece 114 and the main cover cylinder 82 may be integrally connected so as not to be broken. In this case, by tearing off the upper removal piece 112 while breaking the first weakened portion 81, the upper removal piece 112 can be used as an operating member for removing the main cover cylinder 82. Therefore, it becomes easy to transmit the force to the main cover cylinder 82 by using the upper removal piece 112, and the main cover cylinder 82 is moved to the auxiliary cover cylinder 83 and the operation piece 111 while the first weakened portion 81 and the second weakened portion 91 are broken. Can be disconnected and removed from
As described above, since the force can be transmitted to the main cover cylinder 82 by using the upper removal piece 112, the main cover cylinder 82 can be easily removed smoothly.
After the main cover cylinder 82 is removed, the lower removal piece 113 can be peeled off while the first weakened portion 81 is broken using the operation piece 111, so that the lower removal piece 113 can be removed smoothly. Similarly, the auxiliary cover cylinder 83 can be easily removed.

Further, as shown in FIG. 14, the discharge container 120 may include a cover 121 having a cover 122 that is openably and closably connected to the cover cylinder 80 via a hinge 123.
As shown in FIGS. 14 to 16, the lid 122 includes a top plate portion 125 covering the top wall portion 71 and the discharge nozzle 73 of the press head 7 from above over the entire area, and an outer peripheral edge of the top plate portion 125. And an inner wall portion 126 extending downward and disposed inside the cover cylinder 80.
On the outer peripheral surface of the inner wall portion 126, a fitting projection 128 is formed, for example, to be undercut-fitted into a connecting hole 127 formed in the cover cylinder 80.

When the cover body 121 is configured as described above, the entire pressing head 7 can be covered with the cover body 121, so that the pressing head 7 can be protected and the pressing head 7 can be protected unless the cover body 121 is removed. , It is difficult for dust or the like to adhere to the ejection hole 6, for example, and the press head 7 can be maintained more clean.
Further, it is possible to effectively prevent the pressing head 7 from being operated unintentionally before removing the cover body 121.

  In addition, it is possible to appropriately replace the components in the above-described embodiment with surrounding components without departing from the spirit of the present invention, and the above-described modifications may be appropriately combined.
