The outer surface of the button member 71 is formed to have the same cross-sectional arc shape as the outer surface of the pressing deformation portion 15 in a normal state (a state where the button member 71 and the pressing deformation portion 15 are not pressed). Thereby, as shown in FIG. 1, the external appearance of the container 1 gives an impression with a sense of unity.
Further, as shown in FIG. 2, the gap between the peripheral edge of the button member 71 and the pressing deformation portion 15 (the top surface portion 14) surrounding the button member 71 is very small, allowing air to pass through but hardly passing water or dust. For this reason, it is possible to almost completely prevent foreign matter from entering the through hole 73B by shielding the button member 71.

  The lower end of the plug member 36 abuts against the coil spring 37 and is constantly urged upward from the coil spring 37. On the middle of the outer surface of the plug member 36, a slope 36 </ b> A having a shape that matches the tapered portion of the upper inner surface of the cylindrical protrusion 23 </ b> A described above is formed. As shown in FIG. 2, in a normal state (a state in which the button member 71 is not pressed), the inclined surface 36A on the outer surface of the plug member 36 is in a state of being in close contact with the tapered portion on the upper inner surface of the cylindrical protrusion 23A. As a result, the internal space of the cylindrical protrusion 23A is closed at the upper end thereof, and the air passage 35 is closed.

  However, as shown in FIG. 9, when the button member 71 is pushed downward against the urging force of the coil spring 37, the outer surface of the plug member 36 is separated from the inside of the upper portion of the cylindrical protrusion 23A. As a result, the air passage 35 communicating between the outside of the container and the inside of the expansion chamber 34 is opened, and the air in the expansion chamber 34 passes through the air passage 35 and is exhausted to the outside. Thereby, after finishing the content application operation, the swelled elastic body 3 can be easily returned to the original state shown in FIG. 2 by a simple operation. As a result, it is easy to restart the coating operation, and it is possible to easily prevent the elastic restoring force of the elastic body 3 from being lost by leaving the expanded elastic body 3 left.

According to the content extruding container 1 of the present embodiment, in a state where the container 2 is filled with a liquid or gel-like content 33, the pressing and releasing of the pressing deformation portion 15 are repeated, whereby a sheet-like elasticity is obtained. The body 3 can be gradually inflated toward the housing part 2 side. Therefore, by controlling the speed and amount for inflating the elastic body 3, the amount and speed of the content to be sent can be arbitrarily controlled.
Further, since the contents 33 are pressed and sent out by the sheet-like elastic body 3, unlike the container of Patent Document 1, an appropriate amount of contents can be sent stably even if the contents 33 are reduced. Can do. In addition, the contents extrusion container 1 of this embodiment becomes a solid form (slightly crushed hemispherical solid form) of the sheet-like elastic body 3 that was originally flat, along the inner surface shape of the housing portion 2. Can inflate up to.
In addition, accommodation or filling of the contents 33 in the accommodation unit 2 may be performed with the lid 7 removed, or may be performed without removing the lid 7 via the delivery path 5.

Further, in the content extruding container 1, the air venting device 24 and the second check valve 29 are integrated so that the intake passage 32 opened and closed by the second check valve 29 surrounds the air passage 35 of the air venting device 24. Therefore, compared with the case where the air venting device 24 and the second check valve 29 are provided at different positions on the top surface portion 14, the area of the pressing deformation portion 15 (that is, the portion where the pressing operation can be performed) on the top surface portion 14. Spread. For this reason, the content extruding container 1 of the present embodiment has a degree of freedom in the portion to be pressed as compared with the case where the air venting device 24 and the second check valve 29 are provided at different positions, and causes the content to be sent out. High operability. Further, in the content extruding container 1, the air venting device 24 and the second check valve 29 are integrated, so that the members exposed to the outside are gathered together in a compact manner and exhibit an excellent appearance.
Further, in the present embodiment, in the air venting device 24, the coil spring 37 that biases the air passage 35 to close is accommodated in a spring holding portion 77A (elastic member housing portion) that forms a part of the air passage 35. Therefore, further space saving of the air bleeding device 24 can be achieved.

  Further, the air venting device 24 in the content extruding container 1 of the present embodiment has a button member 71 connected to the plug member 36, and the plug member 36 is pressed by the hand so that the plug member 36 is coil spring 37. The air passage 35 is opened against the urging force. The button member 71 is a cover body that covers the upper side of the intake passage 32. For this reason, it is possible to prevent foreign matters from being mixed into the intake passage 32 and to improve the design by enhancing the sense of unity of the appearance with the pressing deformation portion 15. Moreover, since the cover body and button member which have such a function can be combined, it is preferable also from the point of suppression of a member number.

Moreover, in the content extrusion container 1 of this embodiment, since the outer surface shape of the button member 71 is matched with the outer surface shape of the pressing deformation part 15, the external appearance of the content extrusion container 1 becomes a more integrated appearance, Design is improved.
Moreover, the clearance gap between the button member 71 and the press deformation | transformation part 15 (top | upper surface part 14) becomes like this. Preferably it is 0.01-5 mm, More preferably, it is 0.05-1 mm.

  Further, in the content extruding container 1 of the present embodiment, the pressurizing means 4 includes the pressurizing chamber 22 in which the internal volume decreases due to the deformation of the pressing deformation portion 15, and between the pressurizing chamber 22 and the elastic body 3. The air intake passage 32 of the second check valve 29 communicates the inside of the pressurizing chamber 22 with the outside of the container, and the air passage 35 of the air venting device 24 is connected to the container 23. The outside communicates with the inside of the expansion chamber 34 formed between the partition wall 23 and the elastic body 3. In other words, the integrated air venting device 24 and the second check valve 29 are a novel mechanism for integrating the air intake passage 32 and the air passage 35 which are two air passages communicating with other spaces in the container. It has become.

Moreover, the content extruding container 1 of this embodiment can press the press deformation | transformation part 15 with the one hand, and can send out the content, holding in one hand. “One hand” means that the right hand is in the right hand, and the left hand is in the left hand.
Therefore, for example, when filling hair or scalp treatment agents such as hair coloring agents such as hair colors, hair growth agents, hair styling agents, shampoos, and massage agents as contents, and applying them to the hair, move the application site It is also easy to perform the coating operation while making it happen. In addition, while performing the coating operation using the content extruding container 1, it is possible to simultaneously perform another operation with the hand that does not have the container.
Examples of the contents to be accommodated and sent out in the contents extrusion container 1 include stationery such as paints, foods such as mayonnaise, ketchup, and the like in addition to the above-described hair or scalp treatment agent. However, the contents in the present invention are not limited to these.

The material of each part of the content extruding container 1 will be described.
For example, a polyolefin-based thermoplastic resin such as polypropylene, a thermoplastic elastomer, or the like can be used as a material for forming the pressing deformation portion 15. From the viewpoint of naturally returning to the original state by releasing the pressure, polypropylene is preferable. Examples of the thermoplastic elastomer include styrene elastomers, polyolefin elastomers, polyester elastomers, polyamide elastomers, and the like.

  Moreover, it is preferable that the press deformation | transformation part 15 is made into the convex curved surface shape of a circular arc shape of a cross section whose curvature radius is 50 mm-100 mm from a viewpoint of returning naturally to an original state after a deformation | transformation.

  Examples of the material for forming the elastic body 3 include rubbers such as ethylene-propylene-diene rubber (EPDM), silicone rubber and natural rubber, and gels such as urethane. The material for forming the elastic body 3 is preferably EPDM from the viewpoint of durability and content resistance.

  Further, in the content extruding container 1 of the present embodiment, by repeatedly pressing and releasing the pressing deformation portion 15, the elastic body 3 can be inflated until almost the entire surface comes into contact with the inner surface of the housing portion 2. And almost all of the contents 33 can be delivered.

  As described above, the content extruding container 1 which is an embodiment of the present invention has been described as an example. However, the present invention is not limited to the above-described embodiment and can be appropriately changed.

For example, in the present embodiment, the air intake passage 32 including the plurality of through holes 73B surrounds the air passage 35 formed by the space in the cylindrical projection 23A, whereby the air venting device 24 and the second check valve 29 are provided. However, instead of this, the hole constituting the intake passage may be a single annular hole, and the air passage 35 of the air venting device 24 may be surrounded by the hole.
Further, either one or both of the reinforcing portion 50 and the thin portion 60 of the pressing deformation portion 15 can be omitted.

  For example, a bellows-like pump mechanism may be provided on the top surface portion 14 as a pressurizing unit.
