Description

  The present invention relates to a pump container and a cosmetic.

  For example, the pump container is provided with a pump for sucking up the contents in the container at the opening of the container containing the contents such as makeup, hair dyeing, face washing and hair washing liquids, and the piston part of the pump. When the user presses the push button attached to the pump, the pump sucks up the contents in the container and discharges it from the discharge port of the push button (for example, see Patent Document 1).

  Then, before the pump container is delivered to the user, the overcap is attached to the pump container so that the pushbutton is covered with the overcap so that the pushbutton is not pressed due to dropping or mishandling of the pump container. It is attached to the attachment part (to prevent malfunction of the push button). In addition, the overcap and the mounting portion of the pump container are attached with one seal or the like so that it can be easily determined visually that the pump container is unused (virginity (unopened visually Securing).

However, in the technique described in Patent Document 1, since it is necessary to attach a new part such as an overcap or a seal to the attachment part of the pump container, the cost of parts for the overcap and the seal and the installation man-hour for attaching the overcap and the seal are required. The production of the pump container requires high costs.
In addition, as the user repeatedly attaches the overcap to the attachment portion of the pump container or removes the overcap from the attachment portion of the pump container, the attachment portion of the pump container may be rubbed. In particular, the mounting part of the pump container with decoration such as vapor deposition on the mounting part of the overcap should be rubbed due to repeated installation and removal of the overcap, and around the mounting part of the pump container and overcap during use. There also exists a problem that the decoration of the attachment part of a pump container or an overcap will peel off in combination with the attached content (for example, cosmetics).

  The problem to be solved by the present invention is to provide a pump container having a small number of parts, a measure for preventing malfunction of a push button, and ensuring unopened visibility.

  In order to solve the problem, a pump container according to the present invention includes a container body having a storage portion for storing contents, a container having an opening formed in the container body, and the contents stored in the storage portion. A pump having a piston portion mounted in the opening so as to be able to suck, a push button body, a button connection portion formed on the push button body and attached to the piston portion, and a protrusion formed on the push button body And a push button having. The protrusion has a protrusion base formed on the push button body and a break portion that breaks from the push button body.

As shown in FIGS. 1 and 3, the cap 50 includes a cap body 51, an opening 58, a mounting portion 53, a contact portion 54, a pressing prevention portion 55, a pressing allowable groove portion 56, and a pump pressing portion 52. And have.

The cap body 51 is formed in a cylindrical shape, and the cap body 51 is formed with an opening 58 penetrating in the cylindrical axial direction. The attachment portion 53 has a cylindrical inner side surface shape, and is formed on the inner side of the opening 58 in the pressing direction Z1 side. The attachment portion 53 is formed with a female screw that is screwed into a male screw formed on the neck portion 14 so that the attachment portion 53 can be watertightly attached to the neck portion 14 of the container body 10. The pump holding portion 52 is formed on the return direction Z2 side of the mounting portion 53 in the opening 58 so that the flange portion 32 of the pump 30 placed on the neck portion 14 can be pressed.
The contact portion 54 is an end portion on the side opposite to the container body 10 (return direction Z2) in the up-down direction Z so as to come into contact with a protrusion 80 described later.

When the pressing button main body 71 of the pressing button 70 is in the pressing preventing rotation position, the pressing preventing portion 55 abuts the pressing direction Z1 side of the rib portion 74 described later on the pressing preventing portion 55, and the piston portion 33 located at the piston upper limit position. Is formed of a plurality of ridges formed in the opening 58 and extending in the up-down direction Z so as not to move toward the piston lower limit position. The push-down preventing portion 55 is not limited in its configuration as long as the piston portion 33 at the piston upper limit position can prevent the movement toward the piston lower limit position. For example, the push-down preventing portion 55 is one ridge extending in the vertical direction Z. It may be formed.
When the pressing button main body 71 is in the pressing allowable rotation position, the pressing allowable groove portion 56 is formed in the opening 58 so that the end portion on the pressing direction side of the rib portion 74 enters and the piston portion 33 can move to the piston lower limit position. It is the groove part formed in this. The configuration of the pressing allowable groove portion 56 is not limited as long as the piston portion 33 does not hinder the movement of the piston portion 33 to the piston lower limit position, and may be a notch shape, for example.
In the present embodiment, the two pressing prevention portions 55 and the two pressing allowable groove portions 56 are alternately formed in the opening 58.

(pump)
As shown in FIG. 4, the pump 30 includes a cylinder body 31, a piston portion 33, a piston urging portion 39, a suction hole 34, and a discharge port 35. When the piston portion 33 moves up and down between the piston upper limit position and the piston lower limit position with respect to the cylinder body 31, the pump 30 sucks the content X in the storage portion 12 from the suction hole 34 and discharges it from the discharge port 35. Is configured to do.
The cylinder body 31 includes a cylinder portion 38 having a cylindrical shape, a flange portion 32 extending from the cylinder portion 38, and a suction hole 34 extending in the vertical direction Z for sucking the contents X formed in the cylinder body 31. And have.
The cylinder body 31 is mounted in the opening 58 so that the contents X stored in the storage unit 12 can be sucked. Specifically, in the cylinder main body 31, when the female screw of the attachment portion 53 is screwed into the male screw of the neck portion 14, the pump pressing portion 52 of the cap 50 and the end portion of the neck portion 14 make the collar portion 32 watertight. It is attached to the opening 58 by being sandwiched between the two.

In the piston stroke range between the piston upper limit position (FIG. 4 (a)) and the piston lower limit position (FIG. 4 (b)), the piston portion 33 has a pressing direction Z1 and a pressing direction from the piston upper limit position to the piston lower limit position. It is attached to the cylinder body 31 so as to move up and down in a return direction Z2, which is the opposite direction to Z1.
The piston portion 33 divides the column outer surface shape portion 36 extending in the return direction Z2, and the column outer surface shape portion 36 into a piston front end portion 36a on the return direction Z2 side and a piston base end portion 36b on the pressing direction Z1 side. As described above, the columnar outer surface shape portion 36 has a protruding portion 37 (FIG. 6B) extending in the circumferential direction.
The discharge port 35 is a hole formed in the column outer surface shape portion 36 that is watertightly connected to the suction hole 34 of the cylinder body 31.

  The piston urging unit 39 is an urging unit having an urging force, such as a compression coil spring. The piston urging portion 39 is housed inside the cylinder body 31 in a compressed state so that the piston portion 33 can apply an urging force in the return direction Z2. Therefore, in a state where the external force in the pressing direction Z1 is not acting on the piston portion 33, the piston portion 33 is located at the piston upper limit position, and an external force larger than the urging force of the piston urging portion 39 is applied in the pressing direction Z1. When acting on 33, the piston urging portion 39 is compressed in the pressing direction Z1, and the piston portion 33 moves to the piston lower limit position.

(Press button)
As shown in FIG. 2, the push button 70 has a substantially cylindrical shape. The push button 70 includes a push button main body 71, a discharge port 72, a button connection portion 73 (FIG. 1), a projecting portion 80, two rib portions 74, and two escape grooves 75.
The push button body 71 has a shape that allows the user to easily hold the push button body 71 between, for example, two fingers (thumb and forefinger), for example, a cylindrical shape. Further, when the user rotates the push button 70, the push button body 71 is configured so that the push button body 71 in which the user sandwiches the push button body 71 with, for example, two fingers (thumb and forefinger) is difficult to slip. The two side portions of the push button main body 71 (the two side portions are portions of the side surface of the push button main body 71 that are rotated 180 ° around the pump rotation axis C) are provided with a plurality of slides and the like. It is preferable that the guide part 71a formed is formed.
A pressing surface 79 to be pressed by the user is formed at one end of the pressing button main body 71 (the end on the return direction Z2 side).
On the side surface of the push button main body 71, a discharge port 72 and a protruding portion 80 are raised.
The protrusion 80 is formed on the discharge port 72 in the pressing direction Z1 side. The protrusion 80 is formed in the same direction as the discharge port 72, but may be formed on the side opposite to the discharge port 72. If the protrusion 80 is formed on the same side as the discharge port 72, the discharge port 72 is positioned so as to cover the protrusion 80 in the vertical direction Z. Difficult to touch things. In addition, if the protrusion 80 is formed on the side opposite to the discharge port 72, it is not necessary to form anything that obstructs the user's visual recognition on the return direction Z2 side of the protrusion 80. Visibility is improved.
The protrusion 80 is preferably formed on the same side as or opposite to the discharge port 72 in the push button body 71 so that the user can easily rotate the push button 70.

  As shown in FIG. 1, a button connection portion 73 is formed inside the push button body 71. The button connection portion 73 is formed in a cylindrical inner side surface shape so as to fit water tightly to the column outer surface shape portion 36 of the piston portion 33. The button connecting portion 73 is configured so that the press button main body 71 is in a press allowable rotation position (in a state where the rotation angle is 90 ° in FIG. 7) with respect to the cylinder main body 31 about the button rotation axis C extending in the press direction Z1 and the return direction Z2. It is attached to the piston portion 33 so as to be rotatable between the pressing-inhibiting rotation position (the state where the rotation angle is 0 ° in FIG. 5).

  The button connecting portion 73 has a provisional fitting state (FIG. 6B) in which only the piston front end portion 36a is fitted in the column outer surface shape portion 36, and a complete fitting to be fitted into the piston front end portion 36a and the piston base end portion 36b. The outer diameter of the ridge portion 37 is slightly larger than the outer diameter of the ridge portion 37 so that the user feels that the column outer surface shape portion 36 has overcome the ridge portion 37 so as to be in a combined state (FIG. 10B). It is preferable to have a small inner diameter.

The discharge port 72 is connected to the button connection portion 73 in a watertight manner. Thereby, the contents X discharged from the discharge port 35 of the piston part 33 are discharged from the discharge port 72 to the outside of the push button 70 via the button connection part 73.
Each rib portion 74 is formed in the push button main body 71 so as to extend from the end of the push button main body 71 on the push direction Z1 side in the push direction Z1. Between the two rib portions 74, a relief groove 75 into which a press-down preventing portion 55 to be described later enters is formed.
Further, each rib portion 74 receives an external force that acts when the push button body 71 is pushed, so that the push button body 71 has a button of the end in the push direction Z1 side so that the push button body 7 is not easily tilted. It is preferable to protrude from a position away from the rotation axis C. The number of rib portions 74 is not limited, but is preferably two or more. Since the user rotates the push button main body 71 to the press-preventing rotation position and the press-permitted rotation position to properly use the pressable state and the non-pressable state, the number of the rib portions 74 is preferably two.

  The protrusion 80 has two columnar protrusion bases 82 formed on the push button main body 71 and an arcuate break part 81 so as to bridge from the tips of the two protrusion bases 82. The breaking portion 81 is formed so as to come into contact with the contact portion 54 and break from the push-down button main body 71 by the vertical movement of the piston portion 33. In the present embodiment, in the push button 70, the protrusion 80 is formed in the same direction as the ejection port 72.

(Pump container shipping status)
As shown in FIGS. 5 and 6, the pump container 1 is shipped in the following state.
First, the piston part 33 is located at the piston upper limit position. The button connection portion 73 is in a temporarily fitted state in which only the piston tip portion 36a is fitted in the column outer surface shape portion 36. The push button main body 71 is located at the push prevention rotation position.
Therefore, even if an external force in the pressing direction Z1 acts on the pressing surface 79 of the pressing button 70, the pressing portion 70 side of the rib portion 74 of the pressing button 70 is prevented from moving in the pressing direction Z1. Since the end portion of the contact portion abuts against the press-down prevention portion 55 of the cap 50, the protrusion portion 80 does not contact the contact portion 54 of the cap 50 and maintains a state where the contact portion 54 is positioned on the return direction Z2 side. . For this reason, the pump container 1 is in a state in which measures for preventing malfunction of the push button 70 have been taken, and unopened visibility is ensured.
The press-inhibiting part 55 and the rib part 74 have the same fitting dimensions as when the temporary fitting state is changed to the complete fitting state, or the pressing-in preventing part 55 and the rib part 74 are in contact with each other. A gap a that is large enough not to be formed is formed.

(How to use the pump container)
Next, the usage method of the pump container 1 by a user is demonstrated.
As shown in FIGS. 5 and 6, in the state of the pump container 1 at the time of shipment, the direction in which the discharge port 72 of the push-down button 70 is raised is set to the base point (angle 0 °) as the push-down prevention rotation position, and the button is rotated. This is expressed as an angle in the counterclockwise direction around the axis C. In the following description, for the sake of convenience, the rotation direction of the push button 70 is counterclockwise, but it may be rotated clockwise (270 °). Both the case of rotating counterclockwise (90 °) and the case of rotating clockwise (270 °) have the same effect.
First, as shown in FIGS. 7 and 8, the user holds the push button 70 oriented at an angle of 0 °, rotates the push button 70 around the button rotation axis C in the counterclockwise direction, and makes an angle of 90 °. Oriented (or oriented clockwise 270 °). As a result, the rib portion 74 is rotated counterclockwise by 90 ° around the button rotation axis C (or rotated clockwise by 270 °), and the pressing allowance groove portion 56 is formed at the tip of the pressing direction Z1 of the rib portion 74. To position. In addition, the press-down preventing portion 55 is positioned ahead of the escape groove 75 in the pressing direction Z1.

Next, as shown in FIGS. 9 and 10, the user presses the pressing button 70 in the pressing direction Z1. At this time, the pressing allowance groove portion 56 is located at the tip of the rib portion 74 in the pressing direction Z1, and the pressing prevention portion 55 is positioned at the tip of the escape groove 75 in the pressing direction Z1, so that the pressing button 70 is pressed. Along with this, the broken portion 81 of the protrusion 80 comes into contact with the contact portion 54. Further, when the user presses down the push button 70, the protrusion base 82 tends to move in the pressing direction Z1 side with respect to the contact portion 54, so that a shearing force is generated between the fractured portion 81 and the protrusion base 82, and is generated. The broken portion 81 is broken by the shearing force.
Further, since an external force to be pressed acts on the push button 70, the button connection portion 73 that is in a temporarily fitted state in which only the piston tip portion 36a is fitted has the button connection portion 73 formed on the column outer surface shape portion 36. It will be in the perfect fitting state which gets over the protruding item | line part 37 and is fitted also to the piston base end part 36b.
Further, since the piston portion 33 resists the biasing force of the piston biasing portion 39 and moves in the pressing direction Z1 until the piston lower limit position, the pump 30 sucks the contents X stored in the storage portion 12 into the suction hole 34. From the discharge port 35 and operates.
For this reason, the content X discharged from the discharge port 35 is discharged from the discharge port 72 via the button connection part 73.
When the cosmetic 100 is used for the first time, the contents X are discharged from the discharge port 35 by repeatedly pressing the piston portion 33 because the contents X are not filled in the pump 30. become.

Next, as shown in FIG. 11, the user stops pressing the pressing direction Z <b> 1 on the pressing surface 79 of the pressing button 70. As a result, an external force in the pressing direction Z1 does not act on the piston portion 33, so that the piston portion 33 moves in the return direction Z2 by the biasing force in the return direction Z2 of the piston biasing portion 39 and stops at the piston upper limit position. .
At this time, since the protrusion base 82 is located on the return direction Z2 side of the contact portion 54, the user can easily recognize that the pump container 1 has already been used by looking at the protrusion base 82.
In addition, since the push button 70 is located at the press allowable rotation position, the press allowable groove portion 56 is positioned at the tip of the rib portion 74 in the press direction Z1, and the press prevention is provided at the tip of the escape groove 75 in the press direction Z1. The part 55 is located. For this reason, the user can easily discharge the contents X such as desired cosmetics from the discharge port 72 only by pressing the pressing surface 79 of the pressing button 70 in the pressing direction Z1 again.
Further, since the button connection portion 73 is in a completely fitted state in which the button connecting portion 73 is fitted to the piston tip end portion 36 a and the piston base end portion 36 b in the column outer surface shape portion 36, the push button 70 can be easily moved from the pump 30. Will not come off.
Further, when the user stops using the pump container 1, the push button main body 71 is rotated around the button rotation axis C so that the push-down preventing portion 55 is positioned on the rib portion 74 in the push-down direction Z1 side. . As a result, even if the user accidentally presses the pressing button 70, the end of the rib portion 74 on the side in the pressing direction Z1 abuts against the pressing prevention portion 55, so that the piston portion 33 hardly moves up and down. The content X in the part 12 hardly protrudes from the discharge port 72.
In addition, a pattern that can visually grasp the pressing prevention rotation position and the pressing allowable rotation position may be printed on the top surface of the contact portion 54. As a result, the user can visually grasp the pressing-down preventing rotational position and the pressing-permitted rotational position from the position of the discharge port 72 or the protrusion base 82 and the guide pattern formed on the top surface of the contact portion 54. .

  According to the pump container 1, the virgin function of the pump container 1 can be canceled by a single operation in which the user pushes the push button 70 or turns and pushes it. Further, when the push button 70 is in the push prevention rotation position, the pump 30 is prevented from being operated by an external force acting on the push button 70 during the transport of the pump container 1. Further, since the pump container 1 does not require a member such as an overcap that has been conventionally required, the number of parts can be reduced and the assembly process of the pump container 1 in the manufacturing factory of the pump container 1 can be reduced. Since the pump container 1 has virginity (unopened visibility) and a malfunction prevention function, it does not require parts such as an overcap, a seal, and a stopper that are conventionally required. The degree of freedom in design can be expanded.

(Second Embodiment)
Hereinafter, a pump container 1a according to a second embodiment of the present invention will be described with reference to FIGS. In addition, about the same structure as the pump container 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIG. 12, the cap 50 a of the container 5 further includes a press-down blocking portion 57 that protrudes toward the button rotation axis C inside the opening 58, and a ridge 59 with respect to the cap 50. Have.
When the button connecting portion 73 is in the temporarily fitted state and the push button main body 71 is in the press preventing rotation position, the press preventing portion 55 is placed in the opening 58 so that the piston portion 33 does not move to the piston lower limit position. The formed rib portion 74 is configured so that the pressing direction Z1 side substantially contacts.
When the button connecting portion 73 is in the fully fitted state and the push button main body 71 is in the press partial allowable rotation position between the press stop rotational position and the press allowable rotation position, the press partial blocking section 57 is This is a member formed in the opening 58 so that the end of the portion 74 on the side in the pressing direction Z1 contacts and the piston 33 does not move to the piston lower limit position.

  When the piston portion 33 moves in the pressing direction Z1 or the return direction Z2 in a state in which the protruding portion 80 is broken from the pressing button main body 71, the protruding portion 59 is deformed while the protruding base portion 82 is elastically deformed. An opening 58 is formed to extend in the circumferential direction about the button rotation axis C so as to get over.

The protrusion 80 is formed at a position where it is not exposed from the opening 58 in the fully fitted state. In general, the portion where the protrusion 80 is broken is not good in design, but the user cannot easily see the portion where the protrusion 80 is broken, so the design of the cosmetic 100 is not impaired.
It should be noted that when the push button main body 71 is located at the press allowable rotation position and the piston portion 33 moves up and down, the protrusion base portion 82 does not come into contact with the protrusion portion 59 in the pressing direction Z1. The portion where the protrusion base 82 is located may be recessed.

(Pump container shipping status)
The shipping state of the pump container 1a is substantially the same as the pump container 1 shown in FIGS.
Therefore, the piston part 33 is located in the piston upper limit position. The button connection portion 73 is in a temporarily fitted state in which only the piston tip portion 36a is fitted in the column outer surface shape portion 36. The push button main body 71 is located at the push prevention rotation position. For this reason, the pump container 1 is in a state in which measures for preventing malfunction of the push button 70 have been taken, and unopened visibility is ensured.

(How to use the pump container)
Next, a method for using the pump container 1a by the user will be described.
First, similarly to the pump container 1 shown in FIGS. 7 and 8, the user holds the push button 70 oriented at 0 °, and rotates the button rotation axis C around the button rotation axis C in the counterclockwise direction at an angle of 90 °. (Or rotate clockwise to 270 degrees each time). As a result, the pressing allowable groove portion 56 is positioned at the tip of the rib portion 74 in the pressing direction Z1. In addition, the press-down preventing portion 55 is positioned ahead of the escape groove 75 in the pressing direction Z1.

Next, as shown in FIGS. 12 and 13, the user presses the pressing button 70 in the pressing direction Z1. At this time, as the push button 70 is pressed, the breaking portion 81 of the protrusion 80 comes into contact with the contact portion 54. Further, when the user presses down the push button 70, a shearing force is generated between the breaking portion 81 and the projection base 82, and the breaking portion 81 is broken by the generated shearing force. The protrusion base 82 moves over the ridge 59 and moves to the pressing direction Z1 side of the ridge 59.
Further, since an external force to be pressed acts on the push button 70, the button connection portion 73 that was in a temporarily fitted state in which only the piston tip portion 36a is fitted is brought into a completely fitted state in which it is also fitted into the piston base end portion 36b. Become.

Next, as shown in FIGS. 14 and 15, the user stops pressing the pressing direction 79 on the pressing surface 79 of the pressing button 70. As a result, an external force in the pressing direction Z1 does not act on the piston portion 33, so that the piston portion 33 moves in the return direction Z2 by the biasing force in the return direction Z2 of the piston biasing portion 39, and the protrusion base 82 Is located in the pressing direction Z1 side of the contact portion 54. As described above, the protrusion base 82 including the portion where the protrusion 80 is broken is not good in design, but the user cannot easily see the protrusion base 82, so the design of the cosmetic 100 is impaired. Absent.
As long as the protrusion base 82 is positioned on the pressing direction Z1 side of the contact portion 54, the protruding base portion 82 may or may not contact the pressing direction Z1 side of the ridge 59. For this reason, since the user cannot visually recognize the protrusion base 82, the user can easily recognize that the pump container 1a is already in use.
In addition, since the push button 70 is located at the press allowable rotation position, the press allowable groove portion 56 is positioned at the tip of the rib portion 74 in the press direction Z1, and the press prevention is provided at the tip of the escape groove 75 in the press direction Z1. The part 55 is located. For this reason, the user can easily discharge the desired amount of the contents X from the discharge port 72 only by pressing the pressing surface 79 of the pressing button 70 in the pressing direction Z1 again.
Further, the button connecting portion 73 is in a completely fitted state in which the button connecting portion 73 is fitted to the piston tip end portion 36 a and the piston base end portion 36 b in the column outer surface shape portion 36, and the protrusion base portion 82 is pressed down of the ridge 59. Since the contact is made in the direction Z <b> 1, the push button 70 is not easily detached from the pump 30.

  As shown in FIG. 16, when the user stops using the pump container 1 a, the button is rotated so that the push-down button main body 71 is positioned so that the push-down part blocking portion 57 is positioned on the rib 74 in the push-down direction Z1 side. The axis is rotated around the axis C (in FIG. 16, the push button body 71 is rotated at an angle of 135 °). As a result, even if the user accidentally presses the pressing button 70, the end of the rib portion 74 on the side in the pressing direction Z1 abuts the pressing part blocking portion 57, so the piston portion 33 hardly moves up and down. The contents X in the storage portion 12 hardly protrude from the discharge port 72. That is, at this time, the positions of the rib portion 74 and the pressed-down partial blocking portion 57 in the up-down direction Z are substantially the same position (a position where they substantially contact).

In addition, the user does not visually confirm the rotation position of the push button 70 only by rotating the push button 70 until the end of the rib portion 74 on the side in the push direction Z1 comes into contact with the partial push-down preventing portion 57. In addition, it is possible to rotate the push button 70 to the partial push allowable position.
In addition, it is preferable to form a guide symbol on the top surface of the contact portion 54 as a guide that makes it easy to visually grasp the pressing prevention rotation position and the pressing allowable rotation position. For example, when the button main body 71 is in the press-permitted rotation position and the press-down prevention rotation position, guide symbols indicating the press-down allowable rotation position and the press-down prevention rotation position are formed on the top surface of the contact portion 54, respectively. Has been. In this way, the user can easily visually grasp the pressing-inhibiting rotation position and the pressing-permitted rotation position from the guide symbol.
Furthermore, it is preferable that a thin convex portion extending in the vertical direction Z is installed in the opening 58 so that the projection base 82 rides on immediately before the push button 70 is rotated to the position where the push button 70 is partially pushed. Accordingly, when the user uses the pump container 1, when the user rotates the pressing button 70 from the pressing-inhibiting rotation position to the pressing-permitting rotation position, the thin protrusion and the protrusion base 82 come into contact with each other. Then, when the push button 70 is rotated with a stronger force, the protrusion base 82 rides on and exceeds the thin convex portion. And since the user can feel the feeling and sound when he / she gets on and above through the push button 70, it can be determined that the push button 70 has surely rotated to the press allowable rotation position.

(Another form of the second embodiment)
Hereinafter, with reference to FIG. 17, the pump container 1b of another form of 2nd Embodiment which concerns on this invention is demonstrated. In addition, about the same structure as the pump containers 1 and 1a, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIG. 17, the end surface 74b on the pressing direction Z1 side of the rib portion 74 and the end surface 55a on the return direction Z2 side of the pressing prevention portion 55b are pressed when the button connecting portion 73 is in the temporarily fitted state. When the push button main body 71 of the button 70a is in the push prevention rotation position, it is the same as the pump containers 1 and 1a except that the push button main body 71 has an uneven shape that meshes with each other.
The pump container 1b in the shipped state has the push button main body 71 centered on the button rotation axis C because the push button main body 71 of the push button 70a is in the push-down preventing rotation position when the button connecting portion 73 is in the temporarily fitted state. Therefore, the end surface 74b on the pressing direction Z1 side and the end surface 55a on the return direction Z2 side of the pressing prevention portion 55b are engaged with each other. For this reason, malfunction of the push button 70a hardly occurs.

(Third embodiment)
Hereinafter, a pump container 1c according to a third embodiment of the present invention will be described with reference to FIGS. In addition, about the same structure as pump container 1, 1a, 1b, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 18 to 21, the push-down button 70 b has a rib convex portion 74 a that protrudes from the rib portion outer surface that is opposite to the button rotation axis C in the rib portion 74.

In the opening 58 of the container 5, a container side pressing prevention groove 91, a rotation suppression step portion 62 a, a container side pressing prevention groove 92, and a step portion 62 b are formed.
The container side push-down preventing groove 91 allows the push-down button 70b to be at the push-down allowable rotation position while maintaining the piston portion 33 in the piston upper limit position when the button connecting portion 73 is in the fully fitted state. It is a groove formed between the ridge 61 and the ridge 62 extending in the circumferential direction of the button rotation axis C so that the rib ridge 74a can move between the pressing prevention rotation position. . That is, the container-side pressing prevention groove 91 is a groove that extends in the circumferential direction around the button rotation axis C and that allows the rib convex portion 74a to move.

As shown in FIG. 21, the ridges 61 and the ridges 62 are shifted in the circumferential direction around the button rotation axis C to be larger than the circumferential width of the rib projection 74a. Is formed. As a result, in the pressing direction Z1, the ridge 62 is positioned between the two adjacent ridges 61, so the rib protrusion 74a inserted between the two adjacent ridges 61 is Then, it comes into contact with the return direction Z2 side of the ridge 62. For this reason, when the push button 70b is attached to the pump 30, even if the push button 70b is strongly pressed, the rib convex portion 74a abuts on the return direction Z2 side of the convex strip portion 62, so that the protrusion 80 is a contact portion. 54 does not touch.
The container side pressing-down preventing groove 91 is arranged so that the piston part 33 does not move to the piston lower limit position when the button connecting part 73 is in the temporarily fitted state and the piston part 33 is located at the piston upper limit position. The rib convex portion 74a is configured to come into contact with the return direction Z2 side of the container side pressing prevention groove 91 (in other words, the pressing direction Z1 side of the convex strip portion 62).

  The container-side pressing-inhibiting groove 92 is a groove formed between the ridge 62 and the ridge 63 extending in the circumferential direction of the button rotation axis C. The container-side pressing prevention groove 92 is a groove that extends in the circumferential direction around the button rotation axis C, and to which the rib protrusion 74a can move. The container side push-down preventing groove 92 is a rib convex portion so that the piston portion 33 does not move to the piston lower limit position when the button connection portion 73 is in the fully fitted state and the piston portion 33 is at the piston upper limit position. 74a is comprised so that it may contact | abut to the return direction Z2 side (in other words, the pressing direction Z1 side of the protruding item | line part 63) of the groove | channel 92 for container side pressing prevention.

  The rotation-inhibiting step 62a is a step that protrudes from the side surface on the pressing direction Z1 side in the container-side pressing-inhibiting groove 91 toward the return direction Z2. As shown in FIG. 21, it is preferable that the rotation inhibiting step 62 a is formed at both ends of the ridge 62.

  As shown in FIG. 20, the stepped portion 62 b is a stepped portion that protrudes from the bottom surface of the container-side pressing prevention groove 91 toward the button rotation axis C. The step portion 62b is preferably formed in the vicinity of the rotation suppression step portion 62a.

(Pump container shipping status)
A method of using the pump container 1c will be described with reference to FIGS.
As shown in FIGS. 18 to 21, the pump container 1 c is shipped in a shipping state in which the button connecting portion 73 is in a temporarily fitted state and the piston portion 33 is located at the piston upper limit position. At this time, the rib protrusion 74a is in a state of being substantially in contact with the return direction Z2 side of the protrusion 62 (position A in FIG. 20).
And since the edge part of the pressing direction Z1 side of the rib part 74 is located in the return direction Z2 side of the protruding item | line part 62, even if the external force of the pressing direction Z1 acts on the pressing button 70b, the rib part 74 of FIG. Since the end on the pressing direction Z1 side comes into contact with the ridge 62, the piston 33 hardly moves up and down.
The two rotation suppression stepped portions 62a are positioned so as to sandwich the rib convex portion 74a in the circumferential direction around the button rotation axis C.
For this reason, even if the push button 70b tries to rotate by some external force in this substantially contacting state, the rib convex portion 74a that slides on the return direction Z2 side of the ridge 62 rotates as the push button 70b rotates. Since the contact with the step 62a for suppression, the push button 70b does not rotate and move to the press allowable rotation position.

(How to use the pump container)
Next, a method for using the pump container 1c by the user will be described.
First, as shown in FIGS. 18 and 19, the rib protrusion 74 a is in a state of being substantially in contact with the return direction Z <b> 2 side of the protrusion 62 (position A in FIG. 20).
Then, the user holds the push button 70b in the direction of 0 °, and rotates the discharge port 72 counterclockwise around the button rotation axis C to an angle of 90 ° as shown in FIGS. Turn (or rotate clockwise to an angle of 270 °).
At this time, when the push button 70b is rotated from the press-preventing rotation position to the press-permitted rotation position in a state where the rib protrusion 74a is substantially in contact with the protrusion 62, the rib protrusion 74a gets over the protrusion 62, The rib protrusion 74a is located between the two protrusions 61 (position B in FIG. 20). Furthermore, the user can confirm that the push button body 71 has been rotated from the locked state (pressing prevention rotation position) to the pressing allowable rotation position with the feeling and sound that the user gets over.

Next, as shown in FIG. 23, the user presses the pressing button 70b in the pressing direction Z1 so that the piston portion 33 moves from the piston upper limit position to the piston lower limit position. At this time, as the push button 70b is pressed, the breaking portion 81 of the protrusion 80 comes into contact with the contact portion 54, and the breaking portion 81 is broken.
When the user presses down the push button 70b, the projection base 82 moves over the ridge 59 and moves in the pressing direction Z1 side of the ridge 59, and the rib protrusion 74a is centered on the button rotation axis C. In the circumferential direction, it passes between the two ridges 62 and is located between the two ridges 63 (position C in FIG. 20).
Since an external force to be pressed acts on the push button 70b, the button connection portion 73 that is in a temporarily fitted state in which only the piston tip portion 36a is fitted has a protruding line in which the button connection portion 73 is formed on the column outer surface shape portion 36. It will be in the perfect fitting state which gets over the part 37 and fits also to the piston base end part 36b.

Next, the user stops pressing the pressing direction Z1 on the pressing surface 79 of the pressing button 70b. As a result, as shown in FIG. 24, the external force in the pressing direction Z1 does not act on the piston portion 33, so that the piston portion 33 located at the piston lower limit position is urged by the urging force in the return direction Z2 of the piston urging portion 39. , Move in the return direction Z2 and stop at the piston upper limit position.
At this time, since the protrusion base 82 is located on the return direction Z2 side of the contact portion 54, the user can easily recognize that the pump container 1c has already been used by looking at the protrusion base 82.
Further, since the button connection portion 73 is in a completely fitted state, the button connection portion 73 is located on the pressing direction Z1 side with respect to the piston portion 33. For this reason, the rib convex part 74a is located between the protruding item | line part 62 and the protruding item | line part 63 in the up-down direction Z (position D of FIG. 20).

Next, as shown in FIG. 25, when the user stops using the pump container 1c, the push button 70b is rotated.
Further, since the button connecting portion 73 is in a completely fitted state, the rib convex portion 74a is located between the convex strip portion 62 and the convex strip portion 63 in the vertical direction Z (the position in FIG. 20). D). For this reason, the rib convex portion 74a can be disposed in the container-side pressing prevention groove 91 only by rotating the pressing button 70b to a position different from the pressing allowable rotation position. As a result, the rib protrusion 74a can hardly move in the pressing direction Z1.

(Fourth embodiment)
Hereinafter, with reference to FIGS. 26 to 31, a pump container 1d according to a fourth embodiment of the present invention will be described. In addition, about the same structure as pump container 1, 1a, 1b, 1c, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIGS. 26 to 31, the cap 50 d has two container projections 102 that protrude from the inner surface of the opening that is on the button rotation axis C side toward the button rotation axis C in the opening 58. In the vertical direction Z, a relief groove 103 is formed on the side of the container protrusion 102 in the pressing direction Z1. The escape groove 103 is formed in the opening 58 so as to extend in the circumferential direction about the button rotation axis C. In the circumferential direction around the button rotation axis C, the length of each container projection 102 in the circumferential direction around the button rotation axis C so that the container projections 102 are formed on the inner surface of the opening at equal intervals. Is preferably ¼ length of the inner surface of the opening.
The pressing button 70d includes a rib-side pressing-inhibiting groove 74c having a U-shaped cross section that is recessed toward the button rotation axis C, and a rotation-inhibiting rib step 74e formed in the rib-side pressing-in preventing groove 74c. Have Although the number of rib step portions 74e for rotation suppression is not limited, in the present embodiment, it will be described as two.
The rib side pressing prevention groove 74c extends in the circumferential direction around the button rotation axis C so that the pressing button 70d can move between the pressing allowable rotation position and the pressing prevention rotation position. The rib side depression preventing groove 74c is a groove through which the container convex portion 102 can move. The rib side pressing prevention groove 74c has a width wider than the width of the container convex portion 102 in the vertical direction Z so that the container convex portion 102 can be guided. In other words, the rib side pressing-down preventing groove 74 c functions as a rail of the container convex portion 102.
Each rotation-inhibiting rib step 74e protrudes from the side surface on the return direction Z2 side in the rib-side pressing-inhibiting groove 74c in the pressing direction Z1. The distance between the two rotation inhibiting rib step portions 74e is preferably longer than the length of the container convex portion 102 in the circumferential direction around the button rotation axis C. With such a configuration, it is possible to prevent the container convex portion 102 from being positioned between the two rotation suppression rib step portions 74e so as to sandwich the container convex portion 102, and the push button 70d from rotating. .

The push button 70d further protrudes from the bottom surface, which is the surface on the button rotation axis C side, of the rib-side depression prevention groove 74c having a U-shaped cross section toward the opposite side of the button rotation axis C. 74f. The number of stepped portions 74f is not limited, but will be described as two in this embodiment.
The distance between the two step portions 74f is preferably longer than the length of the container convex portion 102 in the circumferential direction around the button rotation axis C. With such a configuration, the container convex portion 102 is positioned between the two step portions 74 f so as to sandwich the container convex portion 102.

(How to use the pump container)
Next, a method for using the pump container 1d by the user will be described.
First, as shown in FIGS. 26 and 27, the rib protrusion 74a is located on the return direction Z2 side of the container protrusion 102.
Then, the user holds the push button 70d oriented at 0 °, and rotates the discharge port 72 counterclockwise around the button rotation axis C to an angle of 90 ° as shown in FIG. 28 (or , Rotate clockwise to angle 270 °). As a result, the push button 70d rotates from the push prevention rotation position to the push allowance rotation position, and the rib convex portion 74a is positioned between the two container convex portions 102.

Next, as shown in FIG. 29, the user presses the pressing button 70d in the pressing direction Z1 so that the piston portion 33 moves from the piston upper limit position to the piston lower limit position. At this time, as the push button 70d is pressed, the breaking portion 81 of the protrusion 80 comes into contact with the contact portion 54, and the breaking portion 81 is broken.
When the user presses down the push button 70d, the protrusion base 82 moves over the ridge 59 and moves in the pressing direction Z1 side of the ridge 59, and the rib protrusion 74a is centered on the button rotation axis C. It passes between the two container convex parts 102 in the circumferential direction.
Since an external force to be pressed acts on the push button 70d, the button connection portion 73 that is in a temporarily fitted state in which only the piston tip portion 36a is fitted has a ridge formed with the button connection portion 73 formed on the column outer surface shape portion 36. It will be in the perfect fitting state which gets over the part 37 and fits also to the piston base end part 36b.

Next, the user stops pressing the pressing direction Z1 on the pressing surface 79 of the pressing button 70d. As a result, as shown in FIG. 30, the external force in the pressing direction Z1 does not act on the piston portion 33, so that the piston portion 33 positioned at the piston lower limit position is urged by the biasing force in the return direction Z2 of the piston biasing portion 39. Then, it moves in the return direction Z2 so as to be positioned at the piston upper limit position.
At this time, the protrusion base 82 is located on the side of the contact portion 54 in the pressing direction Z1. At this time, the protrusion base 82 may be locked to the ridge 59 or may not be locked. For this reason, since the fracture | ruptured protrusion base 82 does not need to be seen by a user, the designability of the cosmetics 100 is maintained. And since the projection part 80 cannot be seen, the user can easily recognize that the pump container 1d has already been used.
Further, since the button connection portion 73 is in a completely fitted state, the button connection portion 73 is located on the pressing direction Z1 side with respect to the piston portion 33. For this reason, in the vertical direction Z, the rib convex portion 74 a is positioned at the same position as the escape groove 103, and the rib-side pressing prevention groove 74 c is positioned at the container convex portion 102.

Next, as shown in FIG. 31, when the user stops using the pump container 1d, the push button 70d is rotated.
Further, since the button connecting portion 73 is in a completely fitted state, in the vertical direction Z, the rib convex portion 74a is located at the same position as the escape groove 103, and the rib side pressing prevention groove 74c is the container convex portion. Located in the section 102. For this reason, the container convex part 102 can be arrange | positioned in the rib side pressing prevention groove | channel 74c only by rotating the press button 70d to the position different from a press allowable rotation position. Thereby, the container convex part 102 contacts the side surface by the side of the return direction Z2 in the rib side pressing prevention groove | channel 74c, even if the external force of the pressing direction Z1 acts on the pressing button 70d. Then, even if the push button 70d tries to rotate in the state where the external force in the push direction Z1 is applied, the container convex portion 102 comes into contact with one of the two rotation suppression rib step portions 74e. Can be prevented from rotating.
When the user uses the pump container 1d again, the user rotates the press button 70d from the press-preventing rotation position to the press-permitted rotation position. At this time, the container convex part 102 contacts either of the two step parts 74f. When the push button 70d is rotated with a stronger force, the container convex portion 102 rides over the stepped portion 74f. And since the user can feel the feeling when the container convex part 102 climbs over the stepped part 74f via the push button 70d, it is confirmed that the push button 70d has surely rotated to the press allowable rotation position. Judgment can be made.

(Shape of pump container protrusion)
Hereinafter, another embodiment of the protrusion of the pump container according to the present invention will be described with reference to FIGS. 32 and 33.
In addition, about the same structure as pump container 1, 1a, 1b, 1c, 1d, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 32, the protruding portion 80a includes one protruding base portion 82a that protrudes from the rib portion 74, and a fracture portion 81a that is formed on the protruding base portion 82a. The fracture portion 81 a is formed in an arch shape so as to follow the shape of the rib portion 74. The protrusion base 82a is connected to the center of the fracture portion 81a. Thus, since the number of protrusion bases 82a is one, the number of protrusions 80a is one, so that virginity (unopened visibility) and malfunction prevention function can be surely exhibited. Can do.

  As shown in FIG. 33 (a), the protrusion 80a has an inclined surface 83 whose thickness in the vertical direction Z decreases as it approaches the button rotation axis C so that the button rotation axis C side of the protrusion base 82a is easily broken. A protrusion base 82a. Since the inclined surface 83 is inclined on the side surface in the pressing direction Z1 side of the protrusion base 82a, the inclined surface 83 contacts the inclined surface 83 so that the contact portion 54 is caught, and the protrusion 80a can be more reliably broken.

  As shown in FIG. 33 (b), the protrusion 80b has an inclined surface 83 whose thickness in the vertical direction Z decreases as it approaches the button rotation axis C so that the button rotation axis C side of the protrusion base 82b is easily broken. A protrusion base 82b having an inclined surface 84 is provided. The inclined surface 84 is inclined on both the side surface on the pressing direction Z1 side and the return direction Z2 side of the protrusion base 82a. Since the protruding base portion 82b has thin side surfaces on both sides in the vertical direction Z, the protruding portion 80b can be more reliably broken.

  As shown in FIG. 33 (c), the protrusion 80c has an inclined surface 84 whose thickness in the vertical direction Z decreases as it approaches the button rotation axis C so that the button rotation axis C side of the protrusion base 82d is easily broken. A protrusion base 82d having a stepped portion 86 is provided. In the inclined surface 84, only the side surface on the return direction Z2 side of the protrusion base portion 82a is inclined, and a step portion 86 that forms a step on the pressing direction Z1 side of the protrusion base portion 82c is formed so that the corner portion of the contact surface 54 is caught. Is formed. Since the corner part of the contact part 54 is easily caught by the level | step difference which the level | step-difference part 86 forms, the projection part 80 can be broken more reliably.
