Description

  The present invention relates to a refill container capable of discharging cosmetics, medicines, other creamy or viscous liquid contents.

2. Description of the Related Art A refill container in which a refill container is stored in an outer container and poured out from a mouth portion or a discharge pump is attached to discharge a content liquid is conventionally known (see, for example, Patent Document 1).
JP 11-301732 A

  However, in the refill container described in Patent Document 1, there is no problem when the container is simply housed in an outer container and the content liquid is discharged and used. However, when the liquid is discharged by installing a discharge pump, as shown in FIG. Since the cross-sectional shape of the bottom lid is an inverted U-shape, there is a problem that when the content liquid is discharged and the inner container is crushed, the bottom lid is greatly tilted and the content liquid is not smoothly discharged.

  An object of the present invention is to solve the above problems, and when a refill container is housed in an outer container and a discharge pump is attached to discharge the content liquid, the bottom lid rises without being extremely inclined, and the inner container An object of the present invention is to provide a refill container that can be crushed smoothly.

  In order to solve the above problems, the present invention provides a refill container comprising a container mouth portion, a bottom lid, and a tubular film as a refill container, wherein the container mouth portion comprises a mouth tube portion, a flange, and an outer periphery. The bottom cover has a welding cylinder and a bottom plate provided at a position lower than the upper end of the welding cylinder, and the tubular film is welded to the outer peripheral wall of the container mouth and the welding cylinder of the bottom lid. A configuration characterized by the above is adopted.

  As an example of the bottom lid, a configuration is adopted in which the bottom plate of the bottom lid is connected to the lower end of the folded portion that extends downward from the upper end of the welding cylinder.

  As an example of the remaining amount prevention spacer, a remaining amount prevention spacer is attached to the container mouth part, and the remaining amount prevention spacer includes a fitting inner cylinder, an outer cylinder, and a bottom plate. Adopted a configuration that is located above the lower end of the outer peripheral wall and is provided with a conical cylinder inclined inward at the lower end of the fitting inner cylinder. A configuration is adopted in which an outer peripheral wall for fitting the spout tube of the container mouth portion is provided as a welded portion.

  As another embodiment of the refill container, a refill container comprising a container mouth portion, a bottom lid, and a tubular film, the container mouth portion being a mouth tube portion and a flange extending from an intermediate portion of the mouth tube portion, Further, a configuration is adopted in which the lower end is composed of an outer peripheral wall located below the flange, and a conical cylinder inclined inward is provided at the lower end of the mouth tube portion.

Since the bottom cover of the refill container is composed of a welding cylinder and a bottom plate provided at a position lower than the upper end, the lower end of the tubular film is bent inward when the liquid content is sucked up by the pump. The tilt can be reduced and the contents can be discharged smoothly.
In addition, by providing the remaining amount prevention spacer, it is possible to discharge the content liquid to the end, and furthermore, a conical cylinder is provided at the lower end of the spacer, and the lower end of the conical cylinder is engaged with the cylinder periphery of the pump. The inside of the refill container was able to be airtight.

  Next, examples of the refill container of the present invention will be described with reference to the drawings.

The refill container A includes a container mouth part A1, a remaining amount prevention spacer A2 attached to the container mouth part A1, a bottom cover A3, and a tubular film A4 connecting between the container mouth part A1 and the bottom cover A3. It has become.

  The container mouth portion A1 includes a mouth tube portion 1, a flange 2, and an outer peripheral wall 3 suspended from the periphery of the flange 2. A screw 4 is screwed on the mouth tube portion 1, and the outer periphery of the flange 2 is provided. A fitting cylinder 5 is suspended inside the wall 3.

  The remaining amount prevention spacer A2 includes a fitting inner cylinder 6 and an outer cylinder 7 that are fitted into the inner circumference of the mouthpiece part 1 of the container mouth part A1, the outer circumferential wall 3 and the fitting cylinder 5, respectively, and the lower end of the outer circumferential wall 3. The bottom plate 8 is located at a higher position, and a conical tube 9 inclined inward is provided below the fitting inner tube 6.

  The bottom cover A3 includes a welding cylinder 10 and a bottom plate 11 provided in the middle of the welding cylinder 10, and has a cross-sectional shape H shape.

  The tubular film A4 is welded to the outer peripheral surface of the outer peripheral wall 3 of the container mouth portion A1 and the outer peripheral surface of the welding tube 10 of the bottom lid A3.

The outer container B includes a side peripheral wall 15, a bottom wall 16, and a cap 17, and the cap 17 includes a mouth tube portion 18 that is screwed on the outer periphery, a flange 19, and a side peripheral wall 20. .
The upper end of the side peripheral wall 15 is provided with a concave groove 21 into which a convex portion 2 a projecting from the outer periphery of the flange 2 of the refill container A is fitted. A screw 22 is screwed at the upper end portion of the cap 17. The side peripheral wall 20 is screwed.

  The pump C is attached to the mouth tube portions 1 and 18 of the refill container A and the outer container B by a mounting cap 25, and a discharge nozzle 27 is attached to the upper end of the stem 26 of the pump C. A suction pipe 28 is attached.

Next, usage modes and operational effects of the refill container of the present embodiment will be described.
The refill container A is filled with a creamy or viscous liquid content and is inserted into the outer container B as shown in FIG.

Next, the cap 17 is fitted on the outer container B, and the refill container A is mounted on the outer container B so that the suction pipe 28 of the pump C is inserted into the content liquid via the mounting cap 25.
When the discharge nozzle 27 is pressed, the content liquid is sucked into the pump C through the suction pipe 28 and discharged from the discharge nozzle 27.

In discharging, according to the suction of the content liquid, at the beginning of the suction, the bottom lid A3 is first raised, and then the lower end portion a of the tubular film A4 is pulled inward, as shown in FIG. In this way, it is folded so as to come into contact with the bottom plate 11.
As a result, the bottom cover A3 rises to a certain position without being largely inclined.

  Next, the pressure is reduced in accordance with the suction of the content liquid, and the tubular film A4 is crushed as shown in FIGS. .

Further, the remaining amount prevention spacer A2 is attached to the upper end portion of the refill container A, and the bottom plate 8 of the remaining amount prevention spacer A2 is located above the lower end of the outer peripheral wall 3 of the container mouth portion A1, At the upper end of the tubular film A4, as the film is crushed, it bends inward from the lower end of the outer peripheral wall 3 and comes into contact with the bottom plate 8 as the pump C sucks up. Does not remain, and all the liquid contents can be discharged smoothly to the end.
Further, since the tip of the conical cylinder 9 is engaged with the outer periphery of the cylinder, the inside of the refill container A is sealed and the content liquid is blocked from outside air, and the content liquid leaks from between the container mouth and the cylinder, It is possible to prevent outside air from entering the refill container.

Next, a description will be given of a second embodiment in which the configurations of the container mouth portion and the remaining amount prevention spacer are changed.
