In FIG. 1, the pump-type container 100 includes a container body 110, a pump head 120, a pump unit 130, and a wing member 140.

  The container body 110 is filled with contents such as shampoo, rinse, gel or gel cosmetic liquid.

  The pump head 120 is provided so as to protrude from the upper part of the container main body 110, and discharges the contents filled in the container main body 110 from the discharge port 121 when pressed.

  The pump part 130 is connected to the pump head 120, and the lower end part extends to the vicinity of the bottom part of the container main body 110. When the pump head 120 is pressed, the contents filled in the container body 110 are sucked up from below and guided to the pump head 120. As a result, the contents filled in the container main body 110 are discharged from the discharge port 121 of the pump head 120.

  The wing member 140 is disposed at the lower end of the pump unit 130 so that the scraping unit 141 contacts the bottom surface of the container body 110. When the pump head 120 is pressed, the pump unit 130 rotates, and the wing member 140 rotates accordingly. As a result, the contents remaining on the bottom surface portion of the container body 110 can be scraped together at the center portion of the bottom surface portion and guided to the suction port 142 of the wing member 140.

  FIG. 2 is an exploded perspective view showing each member of the pump-type container 100 according to the embodiment of the present invention. The pump head 120 is connected to the pump unit 130 in a container main body (not shown), and at that time, a spring material 122 is incorporated therein. When the pump head 120 is pressed, the contents filled in the container body are sucked up by the pump unit 130 and discharged from the discharge port 121. Thereafter, the pressed pump head 120 is returned to its original position by the spring material 122.

  The pump unit 130 includes a cylinder cap 131 and a piston shaft 132, and the cylinder cap 131 is attached so as to cover a part of the piston shaft 132. The cylinder cap 131 is provided with a spiral groove 133 on its surface, and a convex portion 134 provided on the piston shaft 132 is fitted in the spiral groove 133.

  When the pump head 120 is pressed, the cylinder cap 131 connected to the pump head 120 moves downward. Since the convex portion 134 is fitted in the spiral groove 133 provided in the cylinder cap 131, the convex portion provided in the piston shaft 132 as the spiral groove 133 of the cylinder cap 131 moves downward. As the piston 134 moves along the spiral groove 133, the piston shaft 132 rotates.

  Here, the spiral groove 133 is provided in the cylinder cap 131 and the convex portion 134 is provided in the piston shaft 132, but the reverse configuration may be employed. Specifically, the piston shaft 132 may be provided with a spiral groove, and the cylinder cap 131 may be provided with a convex portion that fits into the spiral groove. Even in this configuration, similarly, when the pump head 120 is pressed, the piston shaft 132 rotates as the cylinder cap 131 moves downward.

  Since the wing member 140 is connected to the lower end portion of the piston shaft 132, the wing member 140 rotates with the rotation of the piston shaft 132.

  As described above, when the pump head 120 is pressed, the contents filled in the container main body 110 are sucked up by the pump unit 130 and discharged from the discharge port 121, and the cylinder cap 131 and the piston shaft 132 are also discharged. The wing member 140 is rotated through the scraper 141, and the contents remaining on the bottom surface in the container main body 110 are scraped to the central portion of the bottom surface by the scraping portion 141.

  Furthermore, a ratchet mechanism for preventing reverse rotation of the wing member 140 is provided. Specifically, the pump-type container 100 has a first ratchet mechanism 143 at a connection portion between the wing member 140 and the pump portion 130, and a first contact portion between the wing member 140 and the bottom surface portion of the container body 110.
