Description

  The present invention relates to a pump dispenser attached to a container port for dispensing a liquid such as shampoo or hand soap, or a sprayer that sprays liquid in a container with the pressure of high-pressure gas in the container, and is suspended from the container mouth mechanism into the solution. The present invention relates to a suction port part used by being attached to a suction port of a suction pipe.

  2. Description of the Related Art Liquid containers having a pump dispenser for dispensing a liquid content such as shampoo and hand soap attached to the mouth are widely used. FIG. 12 is an example of such a container. The pump dispenser 51 has a pump mechanism inside and is attached to the container opening so as to seal the container 50. From the lower part of the pump dispenser 51, a suction pipe 52 for sucking up the inner solution is suspended near the bottom of the container. When the head 53 of the pump dispenser 51 is pushed down manually, a certain amount of the internal solution is sucked up through the suction pipe 52 by the pump mechanism and discharged from the discharge port 54 attached to the head 53. The suction port 55 at the lower end of the suction pipe 52 is simply cut obliquely at the lower end of the cylindrical suction pipe 52. Such a suction pipe is also used for a sprayer that sprays the liquid in the container with the pressure of the high-pressure gas in the container.

  When the remaining amount of the internal solution decreases and the liquid level becomes lower than the suction port 55, the remaining internal solution can no longer be sucked up by the pump dispenser 51. In the suction port structure in which the lower end of the cylindrical suction pipe 52 is simply cut obliquely, the amount of the solution remaining without being sucked up is large. Therefore, the structure of the suction pipe 52 and the lower end suction port 55 for reducing the residual amount. Various proposals have been made.

  For example, Patent Document 1 discloses a bottle in which a suction portion is provided at a lower end portion of a suction pipe and a plurality of liquid inflow ports are provided on an outer peripheral portion thereof. However, if the liquid inlet is provided in the outer peripheral portion, the liquid below the inlet cannot be sucked up. Further, in a container having a structure in which the bottom center part is raised, the liquid in the lower part around the raised part cannot be sucked up and remains. Patent Documents 2 and 3 propose a structure in which a tip portion that extends downward is provided at the lower end of the suction pipe, and two notches are provided at the tip portion. However, in this case as well, in a container having a structure in which the bottom center portion is raised, the liquid remains in the lower portion around the rise.

Japanese Patent Application Laid-Open No. 2004-30000 Special table 2012-532809 gazette JP-A-60-99358

  The present invention has been made to solve these problems of the prior art, and the problem is that the container is not sucked up by being attached to a liquid container to which a pump dispenser is attached or a suction pipe suspended in the sprayer. An object of the present invention is to provide a suction port component that can reduce the amount of liquid remaining in the inside as much as possible.

  The invention according to claim 1 for solving the above-mentioned problem is a suction port component attached to a suction port of a suction pipe that is suspended in the internal solution from a suction mechanism attached to the container port in order to suck up the liquid in the container. The tube has a bottomed tubular tube and a plurality of suction branch pipes extending radially downward from the side wall near the inner bottom of the tube through the side wall so that the inner diameter of the tube can fit the suction pipe Each suction branch is made of a flexible material, the tip extends to a position below the bottom of the tube, the tip is closed, and the lower surface near the tip The suction port part is characterized in that a plurality of suction holes are formed in the side wall.

  If the suction port part configured as described above is attached to the lower end of the suction pipe and the suction pipe is pushed in so that the bottom surface of the suction part is in contact with the bottom of the container, the suction branch pipe is bent and the side wall on the lower side of the branch pipe The plurality of suction holes are close to the bottom of the container. Thereby, almost all the liquid in the liquid container can be sucked up by the pump dispenser.

  According to a second aspect of the present invention, in the suction port component according to the first aspect, a cylindrical wall surrounding the suction hole is formed in the outer opening of the suction hole, and an inner solution is formed on the cylindrical wall. This is a suction port component characterized in that a cut is formed to allow the water to enter the inside of the wall.

  With such a configuration, since the internal solution passes through the slit and is sucked into the suction hole, the suction hole is prevented from coming too close to the bottom surface of the container.

  Further, the invention described in claim 3 is characterized in that, in the suction port component according to claim 1 or 2, the tube is formed integrally with the suction pipe instead of inserting the suction pipe into the tube. It is a suction port part.

  When the shape of the container is determined, the length of the suction pipe portion can be determined so that the bottom surface of the suction port component is close to the bottom surface of the container. With such a length, the suction branch pipe bends and comes into contact with the bottom surface of the container, and the suction hole comes close to the bottom surface of the container, so that the same effect as in the first aspect of the invention can be obtained.

It is sectional drawing at the time of forming the suction inlet component 4 and the suction pipe 3 integrally. It is an example of sectional drawing of the conventional liquid container which attached the pump dispenser.

  Hereinafter, an embodiment of a suction port component according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a state in which a suction port component 4 is attached to a lower end of a suction pipe 3 suspended from a pump dispenser 2 attached to the mouth of a liquid container 1. The portion below the line A-A is depicted in a longitudinal sectional view. 2 is a front view of the suction port component 4, FIG. 3 is a plan view, FIG. 4 is a bottom view, and FIG. 5 is a cross-sectional view taken along the line BB in FIG.

  The suction port component 4 includes a bottomed cylindrical tube 5 and a plurality of suction branch pipes 6 extending radially downward from the side wall near the inner bottom of the tube 5 through the side wall. The upper opening of the tube 5 has an inner diameter equal to the outer diameter of the suction pipe 3 so that the suction pipe 3 can be inserted. The sucking branch pipe 6 extending obliquely downward is dimensioned such that its tip is positioned below the bottom surface 7 of the tube 5 and the tip is closed. A plurality of suction holes 8 are formed in the lower side wall near the tip so as to open downward. A reinforcing member 9 is attached to the attachment portion of the suction branch pipe 6 to the tube 5 in order to close the gap and maintain the attachment angle of the suction branch pipe 6. The suction branch pipe 6 is made of a flexible material. The suction branch pipe 6 is made of a flexible material.

  The suction port part 4 is attached as follows. As shown in FIG. 6, before the pump dispenser 2 is attached to the mouth of the liquid container 1, the lower end of the suction pipe 3 suspended from the pump dispenser 2 is slightly fitted into the upper opening of the suction port component 4. In this state, the pump dispenser 2 is lowered and fixed to the mouth of the liquid container 1. As it is lowered, the bottom surface 7 of the tube 5 comes into contact with the bottom surface 12 of the liquid container 1 as shown in FIGS. When further lowered from this state, the suction port part 4 does not descend, so that the insertion depth of the suction pipe 3 into the suction port part 4 increases. When the pump dispenser 2 is finally fixed to the mouth of the liquid container 1, the bottom surface 7 of the suction port component 4 is in contact with the bottom surface 12 of the liquid container 1 as shown in FIGS. 1 and 7.

  When the bottom surface 7 of the suction port component 4 is in contact with the bottom surface 12 of the liquid container 1, the suction branch pipe 6 extending below the bottom surface 12 of the suction port component 4 is flexible as shown in FIGS. Bend. When bent, the lower opening of the suction hole 8 provided on the lower surface near the tip is in a state close to the bottom surface 12 of the liquid container 1 as shown in FIG. 7 when the bottom surface 12 of the liquid container 1 is flat. . Even when the bottom surface 12 of the liquid container 1 is raised as shown in FIG. 1, the lower opening of the suction hole 8 is close to the bottom surface 12. (1) of FIG. 8 is a cross-sectional view along the line CC passing through the center of the suction hole 8 in FIG. Since the tip of the suction hole 8 is closed, when the pump dispenser 2 is operated, the inner solution is sucked into the suction branch pipe 6 through a slight gap between the bottom surface of the liquid container 1 and the opening of the suction hole 8. The sucked inner solution is sucked up through the sucking branch pipe 6 and the sucking pipe 3 and discharged from the discharge port 10.

  If the lower opening of the suction hole 8 is too close to the bottom surface of the liquid container 1 and the gap is too narrow, as shown in FIG. 8 (2), the suction hole 8 is not directed straight down, but at a slightly inclined angle. It is good to provide. In any case, when the suction port component 4 of the present embodiment is adopted, the suction hole 8 for the inner solution is brought close to the bottom surface 12 at the bottom of the liquid container 1, so that almost all the liquid in the liquid container 1 is used. Can be sucked up by the pump dispenser 2. FIG. 1 shows the case where the center of the bottom surface of the liquid container 1 is raised upward, and FIG. 7 shows the case where the bottom surface 12 is flat. In either case, the suction branch pipe 6 has a tip extending obliquely downward. Therefore, the suction hole 8 is close to the bottom surface 12.

(Modified embodiment)
The suction port part 4 described above may be modified as follows.
(No. 1) When there is a concern that the suction hole 8 of the suction branch pipe 6 is too close to the container bottom surface 12 and the opening is blocked, as shown in FIGS. A cylindrical wall 13 with a cut 14 may be provided. 9A is a bottom view as viewed from the opening side of the suction hole 8, FIG. 9B is a side view, and FIG. 10 is a cross-sectional view of the suction hole 8 portion. Since the inner solution is sucked into the suction hole 8 through the cut 14, the suction hole 8 is not blocked.

(Part 2) In the above embodiment, the suction port component 4 is attached to the suction pipe 3 suspended from the pump dispenser 2, but the suction port component 4 and the suction pipe 3 may be integrally formed. FIG. 11 is a cross-sectional view of such a configuration. When the size of the liquid container 1 is determined, the dimensions up to the container bottom surface 12 are known, so that the suction pipe portion 3a is placed so that the bottom surface 7 of the suction port component 4a is close to the container bottom surface 12. Decide the length. In this way, the suction branch pipe 6 can be bent and contact the container bottom surface 12, and the suction hole 8 can be brought into contact with the container bottom surface 12.

  In the drawings, 1 is a liquid container, 3 is a suction pipe, 4 is a suction port part, 5 is a tube, 6 is a suction branch pipe, 8 is a suction hole, 13 is a cylindrical wall, and 14 is a notch.
