Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a discharge container for containing contents having relatively high viscosity and poor fluidity, such as face-wash cream, foundation, and 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 down, which is convenient for liquids having low viscosity and good fluidity.

However, when the content is a face-washing cream, foundation or the like having a relatively high viscosity and poor fluidity, a large amount of the content may remain without being discharged, which is very uneconomical.

By the way, instead of this type of suction pipe,
There is one in which the rising bottom is slidably inserted into the body of the container body (Japanese Utility Model Laid-Open No. 55-38783 and Japanese Utility Model Laid-Open No. 59-55920). In this case, since the rising bottom rises in proportion to the discharge amount, it is not necessary to introduce the outside air accompanying the discharge of the contents into the container body, and even if the contents have a relatively high viscosity and poor fluidity. It is possible to discharge the entire amount.

However, if air enters the container body, the operation of the pump is obstructed by this air and proper discharge cannot be obtained, so it is necessary to prevent the invasion of air when filling the contents. This cannot be done easily and filling of the contents is not easy.

In addition, it is basically disposable, and it is extremely uneconomical because it is disposable including a pump with a complicated structure and a high value, and it is a form in which the container body is temporarily replaced with one filled with contents in advance. As a result, even if the consumer reuses only the pump, the pump cannot be easily attached and detached.

Furthermore, since the rising bottom body is an integral body, it is not easy to provide both airtightness / watertightness and rigidity.

A skirt is also formed on the outer peripheral part to increase its airtightness and watertightness, but such an skirt needs to be formed so that its outer diameter is slightly larger than the inner diameter of the body part. It is not easy to fit it, especially from the expanded end.

The present invention is intended to solve these problems, and also to be able to use a general pump itself which is used for low viscosity only by removing the suction pipe. It is a thing.

[Means for Solving the Problems] In order to achieve the above object, the present invention is provided with a push-down discharge head 3 at a mouth / neck portion 11 of a container body 1 in which a rising bottom 4 is slidably mounted in a tubular body portion 12. In the discharge container equipped with the pump 2, the inner diameter and length of the mouth / neck portion 11 are adapted to the insertion of the pump 2, and the lower portion of the mouth / neck portion 11 is squeezed into a funnel shape so that the lower end of the fitting portion has a small diameter. The pump 2 inserted in the mouth / neck portion 11 is detachably supported on the upper part of the mouth / neck portion 11 and the suction port 21 at the lower end of the pump 2 is fitted to the lower end of the mouth / neck portion. It is characterized in that the rising bottom 4 is fitted in the joint portion 13 in an airtight manner and can be freely inserted and removed, and the rising bottom 4 is formed by fitting a relatively soft bottom member 42 on a relatively hard receiving member 41. To do.

In the rising bottom 4, the relatively hard receiving member 41 ensures the required rigidity in the rising bottom, and the relatively soft bottom member 42 with respect to the body portion 12 of the container main body. Securing the required airtightness and watertightness of the rising bottom. And these things make the form of the airtight and watertight contact part to the trunk | drum 12 in the bottom member 42 suffice by surrounding the protrusion 423 in the periphery, Therefore Therefore, the raising bottom 4 is in the trunk | drum 12 inside. To insert into, simply push it in.

When filling the contents in the body 12 of the container body 1, the pump 2 is removed from the mouth / neck part 11 of the container body 1, and the mouth / neck part 11 is placed with the raised bottom 4 at the upper limit.
An injection nozzle is inserted into the lower part of the mouth and neck, and the tip is guided to the funnel-shaped lower part of the mouth and neck, and is inserted into the fitting portion 13 at the lower end of the mouth and neck, and the contents are injected from the injection nozzle into the body 12. Following this injection, the rising bottom 4 gradually descends and finally reaches the lower limit position shown in the figure. In such filling, air does not enter from the outside. After the filling, the injection nozzle is pulled out, the pump 2 is inserted into the mouth / neck portion 11 to be supported by the mouth / neck portion 11, and the suction port 21 at the lower end of the pump is airtightly fitted to the fitting portion 13 at the lower end of the mouth / neck portion.

Next, when the content is to be discharged, the push-down discharge head 4 may be pressed and released. By this operation, the pump 2 is activated and the content is sucked up from the suction port 21 into the pump 2. Then, it is pressurized and ejected from the nozzle 31 of the downward ejection head 3.

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 4 rises, and the content moves overall upward. At this time, in the rising bottom 4, the relatively hard receiving member 41 secures the basic form of the relatively soft bottom member 42, and the relatively soft bottom member 42.
Presses against the inner peripheral surface of the body portion 12 to ensure airtightness and watertightness of sliding.

[Example] The drawings show a discharge container made of synthetic resin according to an example of the present invention.

In the figure, 1 is a container body, 2 is a pump that is detachably attached to the neck portion 11 of the container body, 3 is a push-down discharge head mounted on the upper end of the pump, and 4 is a cylinder of the container body. A rising bottom 5 slidably mounted in the cylindrical body 12 is a cap detachably attached to the outside of the pressing discharge head.

The container body 1 has a pump 2 with an inner diameter and a length of the mouth / neck portion 11.
The interior of the cylinder 20 part of the
The upper half 11a is provided with a thread around the outer periphery, and the lower half 1
1b is squeezed into a funnel shape, the lower end of which is formed into a fitting portion 13 having a small diameter, and a dish-shaped fixed bottom 14 which is a separate member is fitted to the lower end of the body 12, and a ventilation hole 15 is provided at an appropriate position of the fixed bottom. The lower half portion 11b of the mouth / neck portion 11 squeezed into a funnel shape is
A small-diameter fitting part at the lower end of the injection nozzle that guides the entrance of the filling nozzle for filling the contents and the attached pump 2 to facilitate the insertion.
At 13, the tip of the inserted injection nozzle and the suction port 21 at the lower end of the pump 2 are inserted and inserted freely. In the figure, 16
Is a decorative member.

The pump 2 is a vertical cylinder pump, which operates by pushing and releasing the push-down discharge head 3 at the upper end,
The liquid is sucked from a small-diameter suction port 21 provided at the lower end of the cylinder 20, pressurized inside the cylinder 20, and the pressurized liquid is ejected from a nozzle 31 of the push-down discharge head 3. Has a mounting screw cylinder 22 on the outside thereof, and is detachably screwed to the upper half 11a of the neck portion 11 of the container body by the mounting screw cylinder, and a small-diameter suction port 21 at the lower end of the cylinder 20 is attached to the container body. It is fitted in the fitting portion 13 in an airtight manner and freely inserted and removed. In the figure, 23 is a head guide cylinder which is erected from the mounting screw cylinder 22, 24 is packing, and 25 is a decorative member.

The rising bottom 4 is formed by fitting and integrating a relatively soft bottom member 42 on a relatively hard receiving member 41, and the receiving member 41 is slidable on the inner peripheral surface of the body 12 of the container body. Bottom wall to fit 41
The short cylinder 412 is erected from the middle portion of 1, and its bottom member 42
The fitting cylinder 422 is hung vertically from the peripheral edge of the bottom plate 421 that bends downward, the fitting cylinder is fitted to the outer periphery of the short cylinder 412, and the ridge 423 is formed on the peripheral edge of the bottom plate 421. Is circumferentially provided, and the ridge is air-tightly and water-tightly pressed against the inner peripheral surface of the body portion 12 of the container body.

Thus, when filling the contents of the body 12 of the container body 1 with the pump 2 removed and the rising bottom 4 raised to the upper limit of the body 12, the injection nozzle is moved to the container body 1. It is inserted into the mouth / neck portion 11 of the above and is inserted into the fitting portion 13 at the lower end of the mouth / neck portion, and the contents are injected from the injection nozzle. In this injection, the contents are not accompanied by air, and the rising bottom 4 gradually descends in accordance with the increase in the amount in the body 12, but at this time, the bottom member
Since the central portion of the bottom plate 421 that bends downward in 42 is pressed downward, the degree of bending further deepens, and the ridges 423 on the peripheral edge are pulled inward slightly, but the body 12

The filling of the contents is carried out mechanically and automatically by the contents manufacturer. On the other hand, on the consumer side, when the content is used, it is replaced with another container body 1 which is pre-filled with the content. However, only the contents may be refilled, and in this case, the above procedure can be easily performed.

After filling the contents, the injection nozzle is pulled out, the cylinder 20 of the pump 2 is inserted into the mouth / neck portion 11 of the container body 1, the mounting screw cylinder 22 is screwed into the upper half 11a of the mouth / neck portion, and the cylinder 20 The small-diameter suction inlet 21 at the lower end is airtightly inserted into the fitting portion 13 at the lower end of the mouth / neck portion 11, and the pump 2 is mounted.

At the time of discharging the contents, it is sufficient to push and release the push-down discharge head 4 and jet it from the nozzle 31 of the press-down discharge head 4 as described above. Bottom member 42
Then, since the central portion of the bottom plate 421 that bends downward is pulled upward, the degree of the bending becomes shallow, and the ridges 423 on the peripheral edge
Although it is slightly pushed out, the pressure contact force to the body portion 12 is strengthened and the airtightness / watertightness is increased.

Further, since the relatively hard receiving member 41 under the bottom member 42 secures the upward direction of the entire rising bottom in the body 12, the rising bottom 4 always has a stable and smooth movement. Obtainable.

[Advantage of Invention] According to the present invention, the rising bottom 4 is supported by the relatively hard receiving member 41.
Since the relatively soft bottom member 42 is integrally formed on the upper part of the upper part, flexibility for the required airtightness and watertightness of the rising bottom 4 can be obtained by the relatively soft bottom member 42. In addition, the required rigidity can be obtained by the relatively hard receiving member 41, and even if the bottom member 42 has flexibility, its basic form can be secured, and therefore, the peripheral edge of the bottom member 42 can be projected. It is possible to retain high watertightness and airtightness with the body portion 12 of the container body only by providing the strip 423, and further, since it is not necessary to make such a ridge 423 into a skirt shape or the like, It is also possible to make it extremely easy to assemble by simply inserting the rising bottom 4 into the body 12 of the container body.

Also, the inner diameter and length of the mouth / neck portion 11 of the container body 1 are adapted to the insertion of the pump 2, and the lower portion of the mouth / neck portion 11 is squeezed into a funnel shape so that the lower end thereof is formed into a fitting portion 13 having a small diameter. Then, the appropriate position of the pump 2 inserted in the mouth / neck portion 11 is detachably supported on the upper portion of the mouth / neck portion 11, and
The suction port 21 at the lower end of the pump 2 is connected to the fitting portion at the lower end of the mouth and neck.
Since it is inserted in 13 airtightly and freely removable,
In filling the contents, the rising bottom 4 is raised to the upper limit, the injection nozzle is fitted into the fitting portion 13 of the mouth / neck portion 11 with the pump 32 removed, and the contents are injected from the injection nozzle. By doing so, the rising bottom 4 can be gradually lowered together with the increase of the content in the body 12, and the content of the facial cleansing cream, foundation, pack, etc., having a relatively high viscosity and poor fluidity, In addition, only the contents can be injected accurately and easily, and the invasion of air can be surely prevented. As a result, even after such contents can be ejected well, the mouth-neck The funnel-shaped squeezing of the lower part of 11 enables the injection nozzle and the suction port at the lower end of the pump.
Can be easily fitted and inserted into the fitting portion 13 at the lower end of the mouth and neck.

Furthermore, when the contents are used up, the consumer can very easily replace the empty container body 1 with the container body 1 pre-filled with the contents, and can reuse the complicated and expensive pump. In addition, it is economical, and in addition, a general pump used for low viscosity can be used only by removing the suction pipe, and the cost can be reduced.

Of course, since the rising bottom 4 rises as the amount of the filled content decreases, the entire amount of the content can be accurately moved upward and can be reliably discharged.
