Description

The present invention relates to a dispensing container that uses a squeeze property of a container body to pour a content liquid into a foamed state.

Patent Document 1 uses the squeeze property of the container body to allow the liquid stored in the container body to merge with air in the gas-liquid mixing chamber disposed therein, and to connect the nets at the upper and lower ends of the cylindrical net holder. In a so-called squeeze foamer container called a squeeze foamer container, a homogeneous foamed liquid is formed by passing through a foam homogenizing cylinder attached with a foam, and the foamed liquid is discharged from a nozzle. Such a device is described, and this type of squeeze foamer container is used in a wide range of applications, such as hair cosmetics, baths, kitchens, and toiletries.
And in this pouring container, when the pressure of the container body is released, the inside of the container body is depressurized by the so-called squeeze back of the peripheral wall of the barrel part that is crushed by the pressure, and the outside air becomes a foam homogenized cylinder Is introduced into the container body through an outside air inflow passage provided on the outer peripheral surface of the container.

Japanese Utility Model Publication No. 7-39948

  Here, in the above-described dispensing container, when the outside air is released into the container body through the outside air inflow path after the pressure of the container body is released, the bubbles accumulated above the foam homogenization cylinder are in the outside air inflow path. There is a problem that the dispensing operability is impaired, for example, the bubbles drawn into the inflow channel become resistance and take time to restore the shape of the body, and the next dispensing cannot be performed immediately.

  Also, in this type of dispensing container, the so-called squeeze back, so-called back-suction effect, causes the foamy liquid remaining in the discharge port or nozzle after the dispensing to flow backward in the direction of the container body, and the liquid after dispensing It can be expected to prevent problems such as cutting, subsequent dripping of liquid from the discharge port, and solidification in the nozzle.However, when foamy liquid is drawn into the inflow passage as described above, Such a back sanction effect is also lowered.

In the present invention, in consideration of the problems in the prior art as described above, in the squeeze foamer type dispensing container, the restoration of the container body by squeeze back after the dispensing operation is achieved smoothly, and in the nozzle The object is to create a structure for fully exhibiting the back-suction effect, and to provide a dispensing container for foamy liquid that has excellent dispensing operability, no dripping, etc. and excellent hygiene Objective.

It is possible to easily and accurately set the disposition position.

Further, a locking projection 28 for positioning the mesh member 31 in the vertical direction is provided around the inner peripheral wall of the base tube piece 22.
Here, FIG. 8 (a) is a perspective view showing the main part in a state in which the suction tube 32 is inserted into the check valve member 21 of the container of FIG. 1, and FIG. 8 (b) is a perspective view showing in FIG. FIG. 9 is a perspective view showing a portion in which the pores 26a are not formed in a longitudinal section. As shown in FIGS. 8 (a) and 8 (b), a hanging cylinder piece 27 is suspended from the inside of the locking protrusion 28. Further, a pair of front and rear vent holes 26a are formed by cutting out two peripheral walls in the front-rear direction of the locking protrusion 28.

Then, the four members described above are assembled and fixed in the following procedure to obtain an assembled state as shown in FIG.
1) The mesh member 31 is fitted into the base tube piece 22 of the check valve member 21 and placed on the locking protrusion 28.
2) The upper end of the suction tube 32 is fitted into the hanging cylinder piece 27 of the check valve member 21.
3) The vertical portion 15c of the tubular portion 15 of the cap body 11 is fitted into the upper end portion of the base tube piece 22 of the check valve member 21, and the cap body 11 and the check valve member 21 are assembled. At this time, the insertion limit of the vertical portion 15 c is determined by the contact piece 18.
4) The screw cylinder 13 of the cap body 11 is screwed into the mouth tube portion 2 of the container main body 1, and the cap body 11 is assembled and fixed to the container main body 1.

  In the assembled state as shown in FIG. 1, the check valve 24 that extends from the upper end rear end of the base tube piece 22 of the check valve member 21 via the swing plate piece 23 a 1 is attached to the cap body 11. The intake hole 17 is closed. At this time, since the intake hole 17 is formed in the planar region S that is the outer surface of the rear end wall 15 bw of the tubular portion 15, the circumferential protrusion 24 a formed in the check valve 24 is opened to the intake hole 17. It can contact | abut to the circumference | surroundings of an edge | tip closely, and the sealing function is exhibited reliably.

In addition, the side walls of the horizontal portion 15 a of the tubular portion 15 of the cap body 11 are sandwiched between the upper end portions of the pair of side plate pieces 25 extending on both side walls of the base tube piece 22.

Next, in FIG. 1, when the squeeze operation is performed so that the body 4 is pressed by hand in the direction indicated by the white arrow in the drawing, the pressure inside the container rises, and the liquid stored in the container body 1 The body L ascends in the suction tube 32 and flows into the gas-liquid mixing chamber R, and gas (air) Ar present in the upper portion of the container passes through the vent hole 26a from the periphery of the upper end portion of the drooping cylinder piece 27. It flows into the liquid mixing chamber R, and the liquid L and the gas Ar are mixed in the gas / liquid mixing chamber R.

  When the mixture of the liquid L and the gas Ar passes through the mesh member 31, fine bubbles are uniformly generated in the liquid L by the action effect of the net disposed at the upper end to form the foam liquid FL. The foamed liquid FL flows along the tubular flow path formed by the tubular portion 15 and is poured out from the discharge port 16 as shown by cross-hatching in the drawing.

Then, when the pouring operation is finished, the manual pressing is released. Then, the peripheral wall of the trunk 4 is restored to its original shape by an elastic restoring force.
FIG. 2 is a vertical side view for explaining the swinging posture of the check valve 24 when the pressure on the body of the container in FIG. 1 is released as described above, and the peripheral wall of the body 4 has the original shape. When restored, the inside of the container is decompressed due to this restoration, and the check valve 24 elastically swings obliquely backward with the base end of the swing plate piece 23a1 as the base end due to the back suction effect, and the intake hole 17 is opened, and outside air enters the inside of the container from the discharge port 16 through the intake hole 17, and in the range from the discharge port 16 to the intake hole 17 in accordance with the flow of the outside air, that is, the horizontal of the tubular portion 15 . part 15 a foamed liquid FL remaining in the is returned to the container interior from the air inlets 17.

According to the back suction effect by the intake hole 17, the outside air flows linearly from the discharge port 16 toward the intake hole 17 and enters the container through the intake hole 17. Thus, the foamed liquid FL can be retracted at an early timing to the region indicated by cross hatching in FIG. 2 while returning from the intake hole 17 into the container. The approach proceeds very smoothly, the peripheral wall of the body 4 is restored at an early stage, the next squeeze operation can be performed immediately, and good dispensing operability can be obtained.
The foam liquid FL remaining in the horizontal portion 15a including at least the vicinity of the discharge port 16 can be reliably returned to the inside of the container body, and the foam liquid FL does not remain in at least the horizontal portion 15a and is used. Problems such as subsequent dripping are sufficiently resolved.

Here, the size and the viscosity of the disposed position of the liquid L of the intake hole 17, the nature of the size of the viscosity and bubbles foamed liquid FL that will be formed, solidification problems such as the tubular portion 15 of the liquid L, further Can be appropriately determined in consideration of the ease of arrangement of the check valve 24 and the like.
Further, the shape of the check valve 24 and the method of arranging the check valve 24 in the intake hole 17 are appropriately determined in consideration of the function as the check valve and the productivity of the check valve member 21 and the productivity related to the assembly process. It is something that can be done.
