  However, in the case of a conventional container with a dispensing pump, when the suction pipe is obtained by vertically cutting the tip portion, a convex wall is formed at the bottom of the container body, but the suction pipe is at the apex region of the convex wall. If the suction pipe abuts perpendicularly to the bottom, the suction pipe attracts the apex area of the convex wall.

  On the other hand, there has also been proposed one in which the suction pipe is cut at the tip, but depending on the bending direction of the suction pipe, the tip of the suction pipe may come into contact with the bottom or the corner of the container body at an angle. Since the same sticking occurs, the problem of poor dispensing cannot be solved.

  In addition, in the case of a container with a dispensing pump in which an inward convex wall is formed in the bottom central area of the container body, if the edge is formed at the tip of the suction pipe, it is difficult to slip along the convex wall of the bottom and is caught. For example, a complicated operation is required to arrange the corners in the filling space.

  The problem to be solved by the present invention is that the suction pipe sticks to the bottom of the container main body and causes poor dispensing, and the work when placing the tip of the suction pipe at the corner of the filling space is complicated. There is.

The present invention relates to a container main body having a filling space for contents and having an inward convex wall formed in the central region of the bottom, and a pouring pump that is attached to the mouth of the container main body to pour out the contents of the filling space A container with a pouring pump, which is connected to the suction port of the pouring pump, and when the pouring pump is mounted, its tip is abutted against the convex wall of the container body. Provided with a suction pipe that contacts and maintains a curved state, and at the tip of the suction pipe is provided with a spherical portion that is slidably point-contacted with the convex wall of the container body to avoid blocking the tip opening of the suction pipe , The spherical portion is composed of a plurality of ribs provided at intervals around the distal end portion of the suction pipe, and the rib has a circular arc shape, and the distal end portion of the suction pipe has a spherical tapered shape. It is characterized by being.

  In the present invention, the length of the suction pipe may be at least longer than the apex of the convex wall of the container body from the suction port of the dispensing pump, but is preferably longer than the length that can reach the lower end in the filling space. . Further, in the present invention, the term “spherical” is not limited to a spherical shape, but is interpreted to include a hemispherical shape.

  The spherical portion can be provided with a small protrusion at the tip thereof that makes point contact with the convex wall of the container body. On the other hand, the container main body can be provided with a small protrusion that makes point contact with the suction pipe in the apex region of the convex wall.

  The base portion of the spherical portion can be formed integrally with the suction pipe. Further, the base of the spherical portion may be a separate member that can be attached to and detached from the suction pipe.

  According to the present invention, when the pouring pipe is attached and the tip end of the suction pipe is disposed at the corner of the filling space or in the vicinity thereof, it is smoothly guided along the convex wall of the container body. Therefore, the assembling work for pouring out the contents remaining at the bottom of the filling space, in particular, the corner becomes easy, and the effect of reducing the remaining amount in the container body is exhibited.

  In addition, according to the present invention, since the tip opening of the suction pipe is formed in the region of the spherical portion, the tip opening of the suction pipe is not blocked by the bottom. Accordingly, it is possible to prevent a poor dispensing due to the front end opening for taking in the contents being closed at the bottom.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a partial sectional view showing a first embodiment of the present invention from the side, and FIGS. 2 (a) and 2 (b) are an enlarged view of a main part of FIG. 1 and a plan view of a suction pipe 4, respectively.

  In FIG. 1, reference numeral 1 denotes a bottle-shaped container body that is blow-molded. The container body 1 includes a mouth portion 1a, a shoulder portion 1b, a trunk portion 1c, and a bottom portion 1d. An inward convex wall 11 is formed in the central region of the bottom 1d, and a bottom wall 12 is integrally formed so as to surround the convex wall 11. As a result, a content filling space R having the innermost surface 12f of the bottom wall 12 as the lowermost end is formed inside the container body 1. The convex wall 11 can also be formed to extend directly to the corner of the container body 1 without interposing the bottom wall 12.

  Reference numeral 2 denotes a dispensing pump that dispenses the contents of the filling space R by a user's manual operation. The dispensing pump 2 includes a cylinder pump 21 that hangs down from the mouth 1a of the container body 1, and a nozzle head 22 that operates the cylinder pump 21 when the user manually moves it up and down. It is detachably attached to the mouth 1a by means such as screwing or undercut fitting through the ring cap 3.

  The suction pipe 4 is connected to the suction port 21a of the cylinder pump 21 and maintains a curved state by abutting the tip portion thereof with the inner surface 11f of the convex wall 11 of the container body 1 when the dispensing pump 2 is mounted. Is provided. The suction pipe 4 has a length from the suction port 21a to the bottom wall 11 and is made of a synthetic resin having flexibility.

  As shown in FIG. 2, a spherical portion 5 is provided at the distal end of the suction pipe 4 so as to make point contact with the inner surface 11f of the convex wall 11 so as to be slidable. The spherical portion 5 constitutes the distal end portion of the suction pipe 4, and is provided with a hollow base portion 5a having an opening 5d communicating with a passage 4a formed inside the suction pipe 4, and spaced around the base portion 5a. The contour shape is an arc shape, and the suction pipe 4 is composed of a plurality of ribs 5b and 5c having a spherical tapered shape.

  The rib 5b has an arcuate contour shape, and, as shown in FIG. 2 (b), four extension portions 5b1 that divide the opening 5d of the base portion 5a into four tip openings 5d1 across the cross shape. Have. The ribs 5c are arranged alternately with the extended portions 5b1 of the vertical ribs 5b at intervals around the openings 5d, and have the same contour shape as the vertical ribs 5b. As a result, the ribs 5b and 5c have a rounded tapered shape at the tip of the suction pipe 4.

  Next, with reference to FIGS. 1 and 2, a method for assembling the container with a dispensing pump according to the present invention will be described.

  When the dispensing pump 2 is attached to the mouth 1a of the container body 1, the tip of the suction pipe 4 abuts on the small protrusion 11a formed in the apex region of the convex wall 11 via the vertical ribs 5b and 5c. As indicated by the dotted line, the fluid flows radially outward of the container body 1. The small protrusion 11a is useful for disposing the tip end portion of the suction pipe 4 to the outer side in the radial direction of the container body 1 and disposing it at the corner portion Re of the filling space R, but is not an essential configuration.
