Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a discharge container for containing a liquid having a relatively high viscosity and poor fluidity, such as a face-cleaning cream, a foundation, and a pack.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, there is a liquid discharge container in which a pump having a push-down discharge head and a suction pipe is attached to the mouth of a container body. In the case of this container, a fixed amount of liquid can be quickly taken out each time the pressing discharge head is pressed, which is convenient for liquids having low viscosity and good fluidity.

However, if the content becomes a fluid such as a face-washing cream or foundation having a relatively high viscosity and poor fluidity, a large amount of the content may remain without being discharged due to its nature.

By the way, in this type, there is one in which the rising bottom is slidably inserted in the body of the container body instead of the suction pipe (Japanese Utility Model Publication No. 55-38783). In this case, since the rising bottom rises in proportion to the discharge amount, it is not necessary to introduce outside air accompanying the discharge of the contents into the container body, and the viscosity is relatively high.
Even if the content has poor fluidity, the entire amount can be discharged.

However, when air enters the container body, this air hinders the operation of the pump and an appropriate discharge cannot be obtained.
At the time of filling the contents, it is necessary to prevent the invasion of air or to remove the invading air, but there is a drawback that neither can be done easily, and therefore the filling of the contents is not easy. In addition, since the rising bottom is a single piece, it is not easy to provide both airtightness / watertightness and rigidity.

After that, there has been proposed a device in which an air outlet with a closing means is provided on the rising bottom so that the air in the container body can be exhausted (Japanese Patent Laid-Open No. 61-81975). That is, a mouth tube is hung from the center of the rising bottom whose outer peripheral portion is formed in a skirt shape, and a stopper with a ventilation groove is temporarily fitted to the mouth cylinder so that ventilation is possible. I am trying to fit it and close it.

However, since the stopper is a member separate from the raised bottom, it has a drawback that it is easily detached in the state of temporary fitting, and it is very inconvenient if the stopper is detached when filling the contents. In addition, since the outer diameter of the skirt-shaped outer periphery of the rising bottom that contacts the body of the container body must be formed to be slightly larger than the inner diameter of the body, it is not easy to fit the body. In this case, it is not easy to provide the rising bottom with both airtightness / watertightness and rigidity.

The present invention seeks to solve these problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pump 3 having a push-down discharge head 4 at a mouth / neck portion 11 of a container body 1 in which a raised bottom 2 is provided in a tubular body 12. In which the exhaust port 5 with a closing means is provided on the rising bottom 2,
A relatively soft bottom member on the upper side of the relatively hard receiving member 21.
The receiving member 21 is formed by fitting and integrating with each other, and the receiving member 21 is slidably attached to the inner peripheral surface of the body portion 12 of the container body at the lower end of the short tube 211 that is loosely inserted into the body portion 12 of the container body. An outward flange 212 to be fitted is provided, and the bottom member 22 has a fitting tube 222 vertically extending from the peripheral edge of the bottom plate 221, and the fitting tube is fitted to the short tube 211, and A ridge 223 is provided around the peripheral portion of the bottom plate 221, and the ridge is pressed against the inner peripheral surface of the body 12 of the container body in an airtight and watertight manner. A mouth tube 51 is vertically provided at a central portion of a bottom plate 221 of the bottom member 22, several cutouts 52 are provided at a lower end of the mouth tube, and an upper end is brought into contact with or close to a lower end of the mouth tube to make a plug body 53. Is arranged so that it can be pushed in, and the plug body is integrally connected to an appropriate place on the inner surface of the short cylinder 211 of the receiving member 21 through several supporting pieces 54.

[Operation] Due to the above-described configuration, when the rising bottom 2 is inserted into the body 12 of the container body 1, it is pushed into the body 12 at the lower end opening from below.

When filling the body 12 of the container body 1 with the contents, the pump 3 is removed from the mouth / neck portion 11 of the container body 1, and the mouth / neck portion 11 is left with the rising bottom 2 positioned at the lower limit. Inject the contents from. Upon this injection, the internal air is discharged to the outside through the mouth tube 51 and the notch 52 of the exhaust port 5, and when the filling is completed, the plug 53 is pushed into the mouth tube 51 and the exhaust port 5 is closed.

Next, the pump 3 is mounted again, and the push-down discharge head 4 is attached.
When is pressed and released, the pump 3 is actuated, the content is sucked up from the suction port 31, and is ejected from the nozzle 41 of the push-down discharge head 4.

Due to this ejection, the content in the body 12 of the container body 1 gradually decreases, the internal pressure becomes negative, the rising bottom 2 rises, and the content moves overall upward. At this time, in the rising bottom 2, the short cylinder 211 of the relatively hard receiving member 21 ensures the basic form of the relatively soft bottom member 22, and the short cylinder 21
The outward flange 212 at the lower end of 1 assures the direction of the rise of the entire rising bottom, and the ridge 223 of the relatively soft bottom member 22 slides in pressure contact with the inner peripheral surface of the body 12. To secure the airtightness and watertightness of.

In addition, when refilling or refilling the contents, the rising bottom 2
In the state in which there is no room for air to enter, it suffices to simply remove the pump 3 from the mouth / neck portion 11 and inject the contents, and it is not necessary to operate the discharge port 5. Instead of refilling, it may be replaced with another container body 1 filled with contents.

[Advantage of the Invention] According to the present invention, the rising bottom 2 is supported by a relatively hard receiving member 21.
A relatively soft bottom member 22 is integrally formed on the upper side of the receiving member 21, and the receiving member 21 is provided with a short cylinder 211 that is loosely inserted into the body portion 12 of the container body. An outward flange 212 that is slidably fitted to the inner peripheral surface of the body 12 is provided, and the bottom member 22 is provided with a fitting cylinder 222 that hangs down from the peripheral edge of the bottom plate 221. Is fitted to the short cylinder 211, and the ridges 223 provided around the peripheral edge of the bottom plate 221 are pressed against the inner peripheral surface of the body 12 of the container body in an airtight and watertight manner. The required air-tightness and water-tightness can be obtained by the relatively soft bottom member 22, and the required rigidity can be obtained by the relatively hard receiving member 21, which makes the bottom member 22 flexible. Even if it has the property, its basic form can be secured, and in addition to this, the airtight and watertight pressure contact of the ridge 223 of the bottom member 22 is effective, and the rising bottom 2 has High airtightness and watertightness can be maintained between the body 12 of the container body and the ridge 223, which is not a skirt, and therefore the rising bottom 2 is attached to the body of the container body. When it is inserted into the portion 12, it can be easily inserted by simply inserting it, and the assembly is extremely easy. Moreover, the outwardly facing flange of the relatively hard receiving member 21 located below the ridge 223.

Are arranged so that the stopper 53 can be pushed in by bringing the stoppers into contact with or close to each other,
Since it is integrally connected to an appropriate position on the inner surface of the short tube 211 of the receiving member 21 via 54, not only can the exhaust gas be accurately obtained before the plug body 53 is pushed, but also the receiving member 21 and the bottom member 22 As long as they are fitted and integrated properly to form the rising bottom 2, the plug body 53 is integrally connected to the rising bottom 2,
The stopper 53 will not be accidentally detached and lost, and there will be no inconvenience when packing the contents.

Further, in filling the contents, the contents may be injected from the mouth and neck while the pump 3 is removed,
Since the exhaust port 5 provided with the closing means is provided on the rising bottom 2, the air in the container body 1 can be appropriately discharged as the contents are injected, and the contents flow with a relatively high viscosity. Even a face-washing cream, foundation, etc. having poor properties can be filled extremely easily and quickly without having to raise the rising bottom 2 once.

Of course, since the rising bottom 2 rises along with the decrease in the amount of the filled contents, the whole amount of the contents can be accurately moved upward and discharged reliably, and the pump 3 does not need a suction pipe. Therefore, the pump 3 can be easily attached and detached, which is very convenient and convenient.
