  In the drawing, reference numeral 110 denotes a container main body having a cylindrical mouth portion 111 that is filled with contents, and the mouth portion 111 is connected to a cylindrical body portion 113 via a flat shoulder portion 112. The container body 110 is made of a synthetic resin having an opaque light-shielding color, and integrally includes a mouth portion 111, a shoulder portion 112, and a body portion 113, and an end portion of the body portion 113 that faces the mouth portion 111 is formed on the container body 110. A bottom lid 114 having an outside air introduction hole h is attached separately.

  Reference numeral 120 denotes a pump attached to the mouth portion 111. Reference numeral 130 denotes a nozzle head that is connected to the pump 120 and operates the pump 120 by repeatedly pressing down and returning to eject the contents.

  Specifically, the pump 120 has a mounting cylinder part 121a that is detachably screwed to the mouth part 111 outside the mouth part 111, and the inside of the mounting cylinder part 121a has a mouth through a top wall 121b. A seal wall 121c is formed integrally with the inside of the portion 111 so as to hang down in a cylindrical shape. A cylinder 122 is attached between the top wall 121b and the seal wall 121c via a seal ring S disposed on the upper end of the mouth 111. The cylinder 122 hangs down from the inside of the mouth portion 111 and has a suction port 120a immediately below the shoulder portion 112.

  Further, the seal wall 121c is integrally formed with an inner cylindrical portion 121d forming an annular groove d inside the seal wall 121c. The inner cylinder portion 121d is fitted inside the cylinder 122, and a return spring Sr that elastically supports the nozzle head 130 is disposed in the annular groove d.

  The nozzle head 130 integrally has a guide tube portion 131 that hangs down integrally from the back surface thereof and forms an internal passage that communicates with the discharge port 130a. The guide tube portion 131 is fitted inside the inner tube portion 121d in a sealed state, and a piston 123 is slidably held inside the guide tube portion 131d. Further, the guide cylinder portion 131 has a function of preventing the piston 123 from being detached, and a pump plunger 124 that pressurizes the contents of a filling space R described later is fitted and held together with the piston 123.

  On the other hand, on the outside of the mounting cylinder part 121a, a cylindrical upstanding outer cover 121e is formed integrally with the mounting cylinder part 121a so as to form an annular groove therebetween. The outer cover 121e is configured such that a gap C is formed between the lower end of the outer cover 121e and the shoulder 112 in a normal state where the nozzle head 130 is not pressed down.

  Reference numeral 140 denotes an intermediate dish that is slidably disposed inside the body 113 and serves as a substantial bottom of the container body 110. In the unused state, as shown in FIG. 1, the intermediate dish 140 has a lowermost part 141 that comes into contact with a cylindrical seat wall 114 a that is integrally provided upright from the bottom cover part 114, and is integrally connected to the lowermost part 141. An annular ridge 142 surrounding the lowermost portion 141 and an outer edge 143 that is integrally connected to the outer edge of the annular ridge 142 and is slidably held inside the body 113.

  Reference numeral 150 is made of a synthetic resin having the same light-shielding color as the container body 110, and is positioned closer to the mouth 111 than the inner dish 140 to form a content filling space R between the inner dish 140 and the inner dish 140. It is an upper plate to do. The bottom plate 150f of the upper plate 150 is in contact with the middle plate 140 just before the top dead center of the middle plate 140 (in this embodiment, the position where the lowermost part 141 comes into contact with the cylinder 122 and the rising of the middle plate stops). It rises by pushing up.

  Specifically, the upper plate 150 includes an outer edge 151 that is slidably held inside the body 113, an inner edge 152 that is slidably held on the outer surface of the cylinder 122 of the pump 120, and the inner edge 152. This is an annular disk member integrally having a cylindrical portion 153 that stands up from between the outer edge portion 151 and the outer edge portion 151 and is slidably held inside the mouth portion 111.

  Further, the upper plate 150 has a protrusion 154 having a C-shaped shape as seen from the upper surface thereof standing up from the upper plate 150 between the outer edge portion 151 and the cylindrical portion 153. On the other hand, the shoulder 112 of the container body 110 is formed with an opening 112a through which the protrusion 154 passes slidably. Accordingly, as shown in FIG. 2, the protrusion 154 can pass through the opening 112 a of the shoulder 112 and move up from the shoulder 112 by raising the upper plate 150.

  Next, the operation of this embodiment will be described.

  First, when the user depresses the nozzle head 130, the air in the filling space R enters the cylinder 122 through the suction port 120a and is pressurized by the piston 123 and the pump plunger 124, and the internal pressure is reduced by depressing the nozzle head 130. When the pressure exceeds a certain pressure, the piston 123 slides inside the guide tube 131 to open the through hole 124a formed in the side wall of the pump plunger 124. Thereby, the air in the filling space R when not in use is discharged from the discharge port 130a of the nozzle head through the passage r inside the guide cylinder part 131 from the through hole 124a.

  Next, when the user releases his / her finger from the nozzle head 130, the nozzle head 130 is lifted by the biasing force of the return spring Sr, and the piston 123 slides inside the guide tube portion 131 to pass through the through hole 124a of the pump plunger 124. Close. As a result, when the nozzle head 130 is further raised, negative pressure is generated in the cylinder 122 and the filling space R, and the contents of the filling space R are introduced into the cylinder 122.

  Thereafter, if the nozzle head 130 is repeatedly pushed down and returned, the pump 120 of the pump 120 can cause the contents to be ejected from the discharge port 130a. At the same time, the inner tray 140 is filled as the contents are ejected. The inside of the body portion 113 rises along the axis O while pushing up the contents by the negative pressure generated in the space R. As a result, the inner tray 140 eliminates the negative pressure that accompanies the ejection of the contents by reducing the capacity of the filling space R.

  Then, the contents disappear, and immediately before the lowermost part 141 of the middle plate 140 comes into contact with the suction port 120a of the cylinder and cannot rise inside the body 113, that is, immediately before the top dead center of the middle plate 140, When the raised portion 142 comes into contact with the bottom surface 150f of the upper plate 150 and the intermediate plate 140 is pushed up, the upper plate 150 rises together with the intermediate plate 140. As a result, the projection 154 on the upper plate passes through the opening 112a of the shoulder 112 and rushes from the shoulder 112 to warn that the content has decreased, and as shown in FIG. Is in contact with the cylinder 122 to indicate that the content is completely lost because the gap C formed with the exterior cover 121e is eliminated.

  According to this embodiment, the protrusion 154 is pushed up from the shoulder 112 of the container body 110, so that the remaining amount of the contents can be visually confirmed. Therefore, according to the present embodiment, the remaining amount of contents can be visually confirmed even when the entire container body 110 is opaque.

  In the present embodiment, the engagement protrusion 111a is formed on the inner side of the mouth portion 111 at a position substantially equal to the shoulder 112, and the engagement protrusion 111 is formed on the cylindrical portion 153 of the upper plate 150. An engaging protrusion 153a that engages with 111a is formed. According to such a configuration, it becomes a guide when the upper plate 150 is raised, and can be kept stable without floating in the filling space R.

  Further, in this embodiment, a decorative display can be provided on the protrusion 154. Note that “display” refers to visually appealing characters, figures, symbols, colors, patterns, or combinations thereof. In addition, as a method of providing the display, a method of directly displaying the projection 154 by printing, labeling, or the like can be given, but it includes attaching another member with decoration to the projection 154 by printing or the like.

  The display member 210 is also made of a synthetic resin having the same light-shielding color as the container body 110, and has a cylindrical base 211 fixed to the outer surface of the mouth 111, and an annular shape connected to the cylindrical base 211 via the hinge 212. It consists of a display unit main body 213. As a result, the projection 154 that has passed through the opening 112a of the shoulder 112 and pushed up from the shoulder 112 pushes up the display unit main body 213 to warn that the content has decreased, as shown in FIG. In addition, when the lowermost part 141 comes into contact with the cylinder 122, it is displayed that the contents are completely lost because the display unit main body 213 completely jumps up and the gap C is eliminated.

  According to this embodiment, the display unit main body 213 of the display member 210 is flipped up by the protrusion 154, so that the remaining amount of the contents can be visually confirmed. Therefore, also in this embodiment, the remaining amount of contents can be visually confirmed even when the entire container body 110 is opaque.

  Furthermore, according to the present embodiment, if the back surface 213f of the display unit main body 213 is decorated, its presence is further emphasized, which is effective in visually confirming the remaining amount.
