Japanese Patent No. 3759428

  However, in the conventional container described above, there is a problem in that the contents may be ejected when the cap is opened.

  The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a discharge container in which the contents in the container body are not easily ejected when the cap is opened.

  A discharge container according to the present invention includes a container main body that contains contents, a discharger that is attached to a mouth portion of the container main body and has a nozzle portion that extends along the axial direction of the mouth portion, and A cap placed on the discharge device, and a discharge port for discharging the contents is formed at the tip of the nozzle portion, and the cap is placed on the discharge device in a state where the cap is placed on the discharge device. In the discharge container provided with a closing portion that closes the discharge port, the nozzle portion includes at least the discharge port, and the discharge port is closed by the closing portion along with the cap along the axial direction. It is characterized by having a movable part that can move.

  Due to such a feature, when the cap is opened, the movable portion moves in the direction away from the mouth portion along the axial direction while the discharge port is closed by the closing portion. Thereby, the inside of the container body is depressurized. Thus, since the inside of the container body is depressurized when the cap is opened, the contents in the container body are less likely to be ejected from the discharge port when the cap is opened.

  Further, in the discharge container according to the present invention, it is preferable that the nozzle portion is provided with an expansion / contraction portion that supports the movable portion and can be elastically deformed in the axial direction.

  Thereby, when opening a cap, the expansion-contraction part is extended and deformed to an axial direction, and the movement to the direction away from the opening | mouth part of a movable part is accept | permitted. In the case where the nozzle portion is configured to include the expansion / contraction portion as described above, the movement of the movable portion can be realized with a simple configuration.

  The discharge container according to the present invention is disposed inside the discharge device, and closes the discharge port from the inside of the discharge device in a state where the movable part is pushed down to the mouth side by the cap, In the state where the cap is removed and the movable portion is advanced, it is preferable that an inner plug is provided that is spaced apart from the discharge port and opens the discharge port.

  Thereby, when the cap is closed, the discharge port is sandwiched and closed from both sides in the axial direction by the closing portion of the cap and the inner plug, so that a good sealing property can be provided. Moreover, when the cap is opened, the inner plug is separated from the discharge port and the discharge port is opened, so that the operability is good.

  Further, in the discharge container according to the present invention, the inner stopper is provided with a valve portion that extends in the axial direction and opens and closes the discharge port, and an upper outer periphery of the enlarged diameter portion formed in a part of the valve portion. It is preferable that the surface is gradually expanded in diameter as it goes downward, and the lower outer peripheral surface of the expanded portion is gradually reduced in diameter as it goes downward.

  As a result, when the contents are discharged and then placed in an upright posture, the contents easily flow down into the container body along the outer peripheral surface of the valve portion, and a liquid pool is less likely to occur in the inner plug.

  Further, the discharge container according to the present invention, the inner plug, a mounting cylinder part mounted on the inner side of the mouth part, a valve part that is disposed on the inner side of the mounting cylinder part and opens and closes the discharge port, A connecting part that connects the mounting cylinder part and the valve part and is provided with a flow hole through which the contents can flow, and the connecting part is provided on the inner peripheral surface side of the mounting cylinder part. The structure which inclines downward toward the outer peripheral surface side of the said valve part may be sufficient.

  As a result, when the contents are discharged and then in an upright posture, the contents easily flow down into the container main body along the upper surface of the connecting portion, and the liquid pool is less likely to occur in the inner plug.

  Further, in the discharge container according to the present invention, an engaging portion is provided on the inner side of the cap, and an engaged portion is provided on the movable portion so that the engaging portion can be detachably undercut. Is preferred.

  In the discharge container having such a feature, when the cap is opened, since the engaging portion of the cap is engaged with the engaged portion of the movable portion, the movable portion is pulled up together with the cap. When the cap is removed, the undercut fitting between the engaging portion and the engaged portion is released, and the cap is removed from the movable portion. Thus, when the cap is opened, the movable part can be reliably moved in the axial direction, and the ejection of the contents can be reliably prevented. In addition, it is preferable to set the fitting force with the cap for moving a movable part larger than the force required in order to move a movable part. As a result, when the cap is opened, the movable portion can be moved away from the mouth portion while the discharge port is reliably closed.

  In the discharge container according to the present invention, when the cap is closed, the movable portion may move after the discharge port is closed by the closing portion, but the movable portion moves toward the mouth side along the axial direction. The discharge port may be closed by the closing portion while moving toward the end, or the discharge port may be closed by the closing portion at the end of movement of the movable portion. When closing the cap, it is preferable that the discharge port is closed by the closing portion (the moving portion is fitted to the cap) at the end of movement of the movable portion in order to avoid an increase in internal pressure of the container body.

  The discharge container according to the present invention makes it difficult for the contents in the container body to be ejected when the cap is opened.

On the lower surface of the upper end wall portion 45, a closing portion 46 for closing the discharge port 36 of the discharge device 3 from the outside of the discharge device 3 is formed. The closing portion 46 is a protruding portion projecting from the lower surface of the upper end wall portion 45, and the closing portion 46 is formed in a curved surface shape that protrudes downward.

  As shown in FIG. 1, the discharge container 1 including the container body 2, the discharge device 3, the cap 4, and the inner plug 5 having the above-described configuration is configured such that the closing portion 46 of the cap 4 is the discharge device when the cap 4 is closed. The distal end portion 38 of the ejector 3 is pressed while closing the third ejection port 36. At this time, the movable part 34 of the discharger 3 is pushed down and moved downward in the axial direction, and the expansion / contraction part 35 is contracted and deformed. Further, when the movable portion 34 moves downward in the axial direction, the lower surface of the distal end portion 38 of the movable portion 34 comes into contact with the upper end of the shaft portion 52 (rod portion 54) of the inner plug 5, and the shaft portion 52 discharges. The outlet 36 is blocked. That is, the discharge port 36 is closed by being sandwiched from both sides in the axial direction by the closing portion 46 of the cap 4 and the shaft portion 52 of the inner plug 5.

  Next, the operation of the discharge container 1 having the above configuration will be described.

  As shown in FIG. 3A, when the cap 4 is closed, first, the cap 4 is put on the discharger 3. At this time, the engaging portion 47 of the cap 4 comes into contact with the upper outer edge of the flange portion 37 of the discharger 3. Subsequently, the cap 4 is rotated around the central axis O with respect to the container body 2, and the female screw 49 of the cap 4 and the male screw 26 of the mouth portion 23 are screwed together. At this time, the cap 4 moves downward relative to the container body 2 while rotating. Further, the downward movement of the cap 4 causes the engaging portion 47 of the cap 4 to press the outer edge on the upper side of the flange portion 37 of the discharger 3 downward, so that the expandable portion 35 contracts and deforms in the axial direction and the movable portion 34 It moves downward together with the cap 4. And the lower surface of the front-end | tip part 38 of the movable part 34 contact | abuts to the upper end of the axial part 52 of the inner stopper 5, and the downward movement of the movable part 34 is latched. At this time, the discharge port 36 is closed by the upper end of the shaft portion 52. Thereafter, by further tightening the cap 4, the engaging portion 47 of the cap 4 gets over the flange portion 37 of the discharger 3, and the engaging portion 47 and the flange portion 37 are undercut fitted. As a result, the closing portion 46 of the cap 4 abuts on the distal end portion 38 of the discharge device 3, and the discharge port 36 is closed by the closing portion 46.

  On the other hand, as shown in FIG. 3B, when opening the cap 4, the cap 4 is rotated around the central axis O with respect to the container body 2 in the opposite direction to when the cap 4 is closed, and the female screw 49 of the cap 4 is rotated. And the male screw 26 of the mouth 23 are released. At this time, the cap 4 moves relative to the container body 2 while rotating. Further, since the engaging portion 47 of the cap 4 is undercut fitted to the flange portion 37 of the movable portion 34, the movable portion 34 is pulled up by the cap 4 that moves upward. As a result, the stretchable portion 35 extends and deforms in the axial direction, the movable portion 34 moves upward together with the cap 4 while the discharge port 36 is closed by the closing portion 46, and the tip portion 38 of the nozzle portion 33 is moved to the shaft portion 52. Separated from the top of the. As a result, the volume of the sealed space of the discharge container 1 is increased by the moving distance D of the movable part 34 described above, so that the inside of the container body 2 is decompressed.

  Then, when the screwing of the female screw 49 of the cap 4 and the male screw 26 of the mouth portion 23 is released, the extension deformation of the expansion / contraction part 35 becomes a limit, and the upward movement of the movable part 34 is restricted. By further raising the cap 4, the undercut fitting between the engaging portion 47 of the cap 4 and the flange portion 37 of the discharger 3 is released, the cap 4 is removed from the discharger 3, and the closing portion 46 of the cap 4 is movable. The tip 34 of the part 34 is disengaged. Thereby, the discharge port 36 formed in the front-end | tip part 38 of the movable part 34 is open | released, and the content in the container main body 2 can be discharged from the discharge port 36 now.

  According to the discharge container 1 described above, since the inside of the container body 2 is decompressed when the cap 4 is opened, the contents in the container body 2 are not easily ejected from the discharge port 36 when the cap 4 is opened. In particular, in the above-described discharge container 1, when the cap 4 is closed, the closing portion 46 of the cap 4 closes the discharge port 36 at the end of the downward movement of the movable portion 34. The rise can be avoided, and the ejection of the contents when the cap 4 is opened can be more reliably prevented.

  Moreover, in the above-mentioned discharge container 1, since the nozzle part 33 provided with the movable part 34 and the expansion-contraction part 35 which supports the movable part 34 and can be expanded-contracted in an axial direction is provided, movement of the movable part 34 is provided. Can be realized with a simple configuration, and the discharger 3 having the movable portion 34 can be configured as a single component integrally formed. Thereby, the number of parts can be suppressed and the trouble of assembling the discharge container 1 can be reduced.

  Further, in the above-described discharge container 1, the discharge port 36 is closed from the inside of the discharge device 3 in a state where the movable portion 34 is pushed down by the cap 4, and the discharge port 36 is removed when the cap 4 is removed and the movable portion 34 is advanced. An inner plug 5 is provided to open the discharge port 36 apart from the discharge port 36. When the cap 4 is closed, the discharge port 36 is sandwiched from both sides in the axial direction by the closing portion 46 of the cap 4 and the inner plug 5. Since it closes, it can have a good sealing property. In addition, when the cap 4 is opened, the inner plug 5 is separated from the discharge port 36 and the discharge port 36 is opened, so that the operability is also good.

  Further, in the above-described discharge container 1, the diameter of the upper outer peripheral surface 56 of the enlarged diameter portion 55 of the shaft portion 52 of the inner plug 5 is gradually increased downward, and the lower outer peripheral surface 57 of the enlarged diameter portion 55 is decreased downward. Since the diameter is gradually reduced, the contents are likely to flow down into the container body 2 along the outer peripheral surface of the shaft portion 52 when the contents are discharged and then brought into an upright posture (the posture shown in FIG. 1). Become. As a result, liquid pool is less likely to occur in the inner plug 5, and problems such as clogging are less likely to occur.

  Further, in the above-described discharge container 1, when the cap 4 is opened, the engaging portion 47 of the cap 4 is undercut fitted to the flange portion 37 of the movable portion 34, and the movable portion 34 is pulled up together with the cap 4. The movable part 34 is reliably moved upward in the axial direction. Thereby, the ejection of the contents when the cap 4 is opened can be reliably prevented.

  As mentioned above, although embodiment of the discharge container which concerns on this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, this invention can also make the expansion-contraction part of the discharger 3 into a bellows-like cylinder part. Further, in the present invention, the expansion / contraction part of the discharger 3 can be a cylindrical part that elastically expands / contracts or reversely deforms. Further, according to the present invention, a straight cylindrical rising cylinder is erected on the inner edge of the top wall portion 30 of the discharger 3, and a movable part is fitted into the rising cylinder, and the movable part is pivoted along the rising cylinder. The structure which can be slid in the direction may be sufficient.

  In the above-described embodiment, when the cap 4 is closed, the engaging portion 47 of the cap 4 gets over the flange portion 37 of the discharger 3 at the end of the downward movement of the movable portion 34 and is undercut and fitted. The closing portion 46 is configured to close the discharge port 36, but the present invention is not limited to this. For example, when the cap 4 is closed, the engaging portion 47 of the cap 4 gets over the flange portion 37 of the discharger 3 and is undercut fitted in the middle of the downward movement of the movable portion 34, and the closing portion 46 of the cap 4 discharges. The outlet 36 may be configured to be closed. Furthermore, the closing part 46 of the cap 4 may already be configured to close the discharge port 36 in a state where the cap 4 is put on the discharger 3.

  In the above-described embodiment, the shaft portion 52 having the enlarged diameter portion 55 at the lower end, the connecting portion 53 formed perpendicular to the central axis O, and the inner plug 5 provided are provided. It is possible to make the inner plug into other configurations. For example, an inner plug 105 configured as shown in FIG. 4 may be used. More specifically, the inner plug 105 shown in FIG. 4 includes a mounting cylinder part 50, a flange part 51, and a shaft part 152 (valve part) that is disposed inside the mounting cylinder part 50 and opens and closes the discharge port 36. , A connecting portion 153 that connects the mounting cylinder portion 50 and the shaft portion 152 is provided. The connecting portion 153 is inclined downward from the inner peripheral surface side of the mounting cylinder portion 50 toward the outer peripheral surface side of the shaft portion 152. That is, the connecting portion 153 is formed in a substantially conical shape that is gradually reduced in diameter downward. The shaft portion 152 of the inner plug 105 shown in FIG. 4 is not provided with the enlarged diameter portion 55 in the above-described embodiment, and the shaft portion 152 is a straight rod-like member. According to the inner plug 105 having such a configuration, when the contents are discharged and then in an upright posture, the contents easily flow down from the flow hole 158 into the container body 2 along the upper surface of the connecting portion 153. Therefore, liquid pool is less likely to occur in the inner plug 105, and problems such as clogging are less likely to occur.

  Further, in the above-described embodiment, the engaging portion 47 is provided on the inner side of the cap 4, and the flange portion 37 that is undercut fitted to the engaging portion 47 is provided on the movable portion 34. Although the movable portion 34 is configured to be lifted together with the cap 4, the present invention can omit the engaging portion 47 and the flange portion 37 described above. For example, instead of undercut fitting, the movable part 34 may be press-fitted and fitted inside the cap 4 so that the movable part 34 can be pulled up together with the cap 4 when the cap 4 is opened. Furthermore, the movable part 34 may not be configured to be pulled up by the cap 4. For example, when the elastic part 35 is elastically contracted and deformed when the cap 4 is closed, the cap 4 is opened, The movable portion 34 can be moved upward by the restoring deformation due to the elasticity of the stretchable portion 35.
