Description

  The present invention relates to a storage container capable of taking out a substantially constant amount of fluid content every time an operation is performed.

Japanese Patent Laid-Open No. 10-24951 JP-A-11-333338

  Conventionally, fluid contents, in particular, general high-viscosity contents such as shampoos, rinses, facial cleansers, and hand creams are sealed in tube containers. The tube container has the advantage that the discharge operation of the contents is simple, the remaining amount is small, and it is easy to handle, but it is difficult to make the degree of pressing with the fingertip against the trunk part, so once The discharge amount of the content liquid due to the discharge operation is not constant, and there is a problem that the content used for each discharge operation is often excessive or insufficient. Pump-type containers are often used for shampoos and rinses, and it is possible to discharge an approximately constant amount of contents with a single push. There was a problem of becoming impossible.

Here, Patent Document 1 describes a fixed amount discharge container using squeeze property. This is provided with an elevating plate that moves by the flow output of the contents generated by pressing the container at the pouring part of the container, and after pouring a certain amount, closes the pouring outlet. The plate is designed to return to its original position after the outside air is sucked from the outlet after pouring, so there is no problem if the content is a low-viscosity liquid. It could not be used because it could not be restored. Further, since the operation of the lifting plate is left to the flow output of the contents, the lifting plate is not sufficiently restored depending on how the container is pressed, and leakage may occur after a certain amount of discharge.
Further, in the invention described in Patent Document 2, a high-viscosity content can be discharged in a certain amount, but the structure is complicated and expensive.

  In view of this, it is an object of the present invention to provide a storage container for contents that can be used for high-viscosity contents and can discharge a substantially constant amount of contents without leakage. .

Is provided with a moving valve 4, and this moving valve 4 is normally arranged at a position away from the discharge port 22, and the above-described pressurization causes the discharge chamber 21 to be located on the side of the discharge port 22. Move so as to approach, and a part of the moving valve 4 covers the discharge port 22 The discharge port 22 can be closed, and the discharge chamber 21 is provided with the elastic body 5 that urges the moving valve 4 in a direction away from the discharge port 22, and the discharge port 22 as described above. When the valve is closed, a balancing gap Y is maintained between the discharge chamber wall surface 33b and the transfer valve 4 around the discharge port 22 except where the transfer valve 4 partially covers the discharge port 22. A container for storing contents is provided.
In addition, the above-described “equilibrium interval Y is maintained” includes a case where the discharge chamber wall surface 33b and the moving valve 4 are in contact with each other accidentally.

  In the invention according to claim 2 of the present application, the discharge chamber 21 is provided with a guide portion 3 for restricting the movement of the moving valve 4. The guide portion 3 is a cylindrical main body portion. 31, one end side of which is arranged on the side of the storage chamber 11 in the discharge chamber 21, and the other end side thereof is arranged on the side away from the storage chamber 11 in the discharge chamber 21, and one end side of the main body 31 is opened. The other end side is closed except for the discharge port 22, and the guide portion 3 has a stopper portion 32 that restricts the movement of the moving valve 4 toward the storage chamber 11 by contact. The stopper portion 32 is provided closer to the storage chamber 11 than the end portion on one end side of the main body portion 31 so as to cover a part of the one end side of the main body portion 31. The contents of the guide part 3 flow from the storage chamber 11 to the inside of the guide part 3. An inflow opening 34 is formed, the movement valve 4 and the elastic body 5 are arranged inside the guide part 3, and the movement valve 4 is regulated along the inner peripheral surface of the main body part 31 in the guide part 3. In this state, the inflow opening 34 is partially blocked by the regulated surface 41a of the moving valve 4 when the moving valve 4 is in the position regulated by the stopper portion 32. Thus, an inflow gap X through which the contents can flow in remains between the one end portion 31a of the main body 31 in the guide portion 3 and the discharge port side end portion 41b in the regulated surface 41a of the moving valve 4. The content storage container according to claim 1, wherein a dimension of the inflow gap X along the axial direction of the discharge chamber 21 is 1 to 3 mm.

  In the invention according to claim 3 of the present application, the discharge chamber 21 is provided with a guide portion 3 for restricting the movement of the moving valve 4, and the guide portion 3 is a cylindrical main body portion. 31, one end side of which is arranged on the side of the storage chamber 11 in the discharge chamber 21, and the other end side thereof is arranged on the side away from the storage chamber 11 in the discharge chamber 21. 3 and the inner wall of the discharge part 2 are arranged with a space allowing the contents to flow in, and a slit 35 through which the contents can pass is provided on the side face of the main body part 31.

However, it is possible to provide a storage container that can be used and can discharge a substantially constant amount of contents without leakage.
Further, when the discharge port 22 is closed, a portion for the balance is provided between the discharge chamber wall surface 33b around the discharge port 22 and the transfer valve 4 except for a portion where the part of the transfer valve 4 covers the discharge port 22. Since the gap Y is maintained, there is a margin between the discharge chamber wall surface 33b and the moving valve 4 by the balance gap Y, and the repulsive force of the elastic body 5 and the pressurization of the container body 1 are present. Thus, the force acting on the moving valve 4 is balanced, thereby preventing the displacement of the moving valve 4 and effectively preventing leakage.

  Further, in the invention described in claim 2 of the present application, in addition to the effect of the invention described in claim 1, an inflow gap X through which contents can flow in remains between the guide portion 3 and the moving valve 4. In addition, by setting the dimension of the inflow gap X along the axial direction of the discharge chamber 21 to 1 to 3 mm, the inflow of the contents from the storage chamber 11 to the inside of the guide portion 3 is facilitated.

It was possible to provide a storage container suitable for the contents.

  Hereinafter, an example of an embodiment of the present invention will be described. FIG. 1 is a perspective view showing the storage container of this example, FIG. 2 is a perspective view showing each of the discharge mechanisms according to the first and second examples of this example, and FIGS. FIG. 5 is a longitudinal sectional view showing a discharge mechanism according to one embodiment, and FIG. 5 is a longitudinal sectional view showing a discharge mechanism according to a second embodiment.

The storage container of this example is as shown in FIG. 1, and includes a container main body 1 configured to be capable of pressurizing the contents and the above-described storage chamber 11. It has the discharge part 2 provided with the discharge chamber 21 which is continuous and has a smaller volume and cross-sectional area than the storage chamber. The discharge part 2 has a discharge port 22 for discharging the contents to the outside of the container.
In addition, in the storage container of this example, the cap 6 which can block | close the discharge outlet 22 at the time of non-use is provided, but this is not essential in this invention.

  The container body 1 is made of plastic or the like, can be deformed by pressing the outer periphery, and can be restored to its original form by releasing this pressing. In this example, the discharge part 2 is a part from which a part of the container body 1 protrudes as shown in FIG. Unlike the container main body 1, the discharge unit 2 is desirably rigid.

  In this example, as shown in FIG. 2, a discharge mechanism for taking out a substantially constant amount of contents is provided in the discharge chamber 21. This discharge mechanism includes a guide portion 3 having a space inside, and a moving valve 4 and an elastic body 5 arranged inside the guide portion 3. First, the first embodiment shown in FIG. 2A will be described below.

  The discharge mechanism according to the first embodiment is mainly used when the contents have a relatively low viscosity of 300 mPa · s or less. According to the experimental results described later, it was confirmed that good discharge was performed when the viscosity of the content was 100 mPa · s or less, and discharge was impossible when the content was 1000 mPa · s or more.

The guide part 3 is for restricting the movement of the moving valve 4 inside the discharge chamber 2.
As shown in FIG. 2A, the guide portion 3 of the first embodiment has a cylindrical main body portion 31, and one end side (the upper side in the drawing) is located on the side of the storage chamber 11 in the discharge chamber 2. The end side (the lower side in the figure) is arranged on the side away from the storage chamber 2 in the discharge chamber 2.
One end side of the main body 31 is opened, and the other end side is closed except for the discharge port 22. In this embodiment, as shown in FIG. 3A and the like, a discharge portion 33 which is a separate member is attached to the other end side of the main body portion 31 by fitting, and the discharge port 22 is connected to this discharge portion. A circular hole is provided at the center of 33. The discharge port 22 is not limited to this, and may be a hole that is formed integrally with the main body portion 31 in a cylindrical shape with one end side closed and provided on the end surface of the closed side.

  As shown in FIG. 3A and the like, the guide portion 3 in this embodiment is arranged so as to occupy almost the entire discharge chamber 21, and includes the inner wall 22 of the discharge portion and the side surface of the guide portion 3. However, there may be provided a gap through which the contents can flow.

  A moving valve 4 is provided inside the guide portion 3. The moving valve 4 is normally arranged at a position away from the discharge port 22 (see FIG. 3A), and by pressurizing the container body 1, the discharge valve 21 moves toward the discharge port 22 side. It moves so that it may approach and the discharge outlet 22 can be closed (refer FIG. 4 (B)).

  As shown in FIG. 3 (A) and the like, the moving valve 4 of this embodiment is formed on the side of the discharge port 22 with respect to the base 41 and the base 41 as shown in FIG. Is also provided with a small diameter portion 42 having a small diameter. Furthermore, a frustoconical fitting protrusion 43 is provided on the discharge port 22 side of the small diameter portion 42. As shown in FIG. 4B, the fitting protrusion 43 is partly fitted into the discharge port 22 to close the discharge port 22 as shown in FIG. As long as the discharge port 22 is closed when at least a part of the movable valve 4 covers the discharge port 22 as in the second embodiment shown in B), the present invention can be implemented in various forms. The storage valve 11 side of the transfer valve 4 is open, and the contents can flow into this portion.

  Further, the moving valve 4 in the present embodiment has a regulated surface 41 a along the inner peripheral surface of the main body portion 31 in the guide portion 3. The regulated surface 41a in the present embodiment is the outer peripheral surface of the base 41 that is the largest diameter portion of the cylindrical bodies with different diameters that are overlapped as described above. Although there is a difference between the regulated surface 41 a and the inner peripheral surface of the main body 31 due to the viscosity of the contents, the movement valve 4 is moved smoothly inside the guide portion 3. And the space | interval of the grade which the free distribution | circulation of the content is prevented is provided.

  In addition to the above, an elastic body 5 that urges the moving valve 4 in a direction away from the discharge port 22 is provided in the guide portion 3. In the present embodiment, a helical spring is used, and one end is arranged at the small diameter portion 42 of the moving valve 4 and the other end is arranged at the discharge portion 33 of the guide portion 3. The type of spring is not particularly limited, and can be implemented in various forms.

  As shown in FIG. 2A, the guide portion 3 of this embodiment has a stopper portion 32 that restricts movement of the moving valve 4 toward the storage chamber 11 by contact. The stopper portion 32 is provided integrally with the main body portion 31 so as to protrude from the one end side end portion of the main body portion 31 toward the storage chamber 11 so as to cover a part of the one end side of the main body portion 31. It is a thing. As a result, the guide portion 3 is formed with an inflow opening 34 that allows the contents to flow from the storage chamber 11 into the guide portion 3 as a gap between the main body portion 31 and the stopper portion 32. In this embodiment, the main body 31 is formed so as to be passed in a cross shape at one end of the main body 31. Further, in this embodiment, a central inflow hole 32a is provided through the cross-shaped intersection portion of the stopper portion 32 so that the contents can flow into the guide portion 3 from the central inflow hole 32a. Has been.

  The discharge mechanism according to the first embodiment formed as described above operates as shown in FIGS. 3A and 3B and FIGS. 4A and 4B. First, in a normal state as shown in FIG. 1 where the container body 1 is not pressurized, the moving valve 4 is pressed by the elastic body 5 and is in contact with the stopper portion 32 as shown in FIG. It is in.

In this state, the inflow opening 34 is partially blocked by the regulated surface 41 a of the movement valve 4. In this state, between the one end 31a of the main body 31 in the guide 3 and the end 41b on the discharge port 22 side of the regulated surface 41a of the moving valve 4, the contents can flow in. The gap X remains.
If the size of the inflow gap X is too large, the contents just flow in from the gap and the movement valve 4 is not moved. If it is too small, the guide section from the storage chamber 11 is used. 3 is difficult to flow into the interior of the container 3, so that the flow of the contents from the storage chamber 11 into the guide portion 3 is facilitated, and a movement valve by pressurizing the container body 1 to be described later It is set as the optimal dimension which can be compatible that the movement of 4 is not inhibited. In determining the size of the inflow gap X, it is necessary to consider the viscosity of the contents. In the present embodiment, this dimension is 1 to 3 mm.

  In order to discharge the contents, first, the storage container is turned upside down from the state shown in FIG. Even in this state, the discharge mechanism still maintains the state shown in FIG. In this state, due to the influence of gravity, a part of the contents existing in the storage chamber 11 flows from the inflow gap X remaining in the inflow opening 34 and fills the inside of the guide portion 3.

  Next, when the container body 1 is pushed and pressurized with the cap 6 removed, the pressure of the contents in the storage chamber 11 becomes higher than the pressure of the contents inside the guide portion 3. The moving valve 4 receives this pressure difference and starts moving downward in the figure. FIG. 3B shows a state in the middle of which the inflow gap X existing between the guide portion 3 and the moving valve 4 is eliminated. In this state, the contents present inside the guide portion 3 between the movement valve 4 and the discharge port 22 are pushed out of the storage container from the discharge port 22 as the movement valve 4 moves. Thereafter, as shown in FIG. 4B, when a part of the fitting projection 43 of the moving valve 4 is fitted into the discharge port 22, the discharge port 22 is closed, and the discharge of the contents is completed. Through this series of processes, a substantially constant amount of contents can be taken out from the discharge port 22.

Then, when the pressure applied to the container main body 11 is eliminated, and the force pressing the moving valve 4 downward in the figure does not work, the elastic body 5 tends to extend, and the moving valve 4 moves upward in the figure. Then, the state returns to the state of FIG.
Here, in the invention described in Patent Document 1, since the lifting plate naturally returned to the original state, there was a possibility that the lifting plate was caught in the middle, but in this embodiment, Since the moving valve 4 is forcibly returned to the original state by the elastic body 5, the moving valve 4 is reliably returned.

  Here, since the raising / lowering plate corresponding to the movement valve 4 described in Patent Document 1 is provided with a passage portion through which the contents can pass, the content liquid passes through the passage portion even during the movement of the elevation plate. It was to pass. For this reason, there is a possibility that the quantitativeness of the discharge amount may not be ensured. On the other hand, in the present invention, only a gap is provided between the guide portion 3 and the movement valve 4 so that the movement of the movement valve 4 is smoothly performed. Has improved.

  In the present embodiment, in the final process during the movement of the moving valve 4, the discharge port 22 is closed (see FIG. 4B) through the state shown in FIG. Here, in the state shown in FIG. 4 (A), the upper end of the overhanging portion 33 a that protrudes into the main body portion 31 for fitting with the main body portion 31 of the discharge portion 33, and the moving valve The lower end of the four small diameter portions 42 coincide with the illustrated lower end. Note that there is a difference equivalent to twice the side gap Z, which will be described later, between the inner diameter dimension of the overhang portion 33a and the outer diameter dimension of the small diameter portion 42. And the content for the capacity | capacitance of the front-end | tip space 23 prescribed | regulated by the overhang | projection part 33a and the movement valve 4 is a discharge port, while the movement valve 4 moves below illustration after the state shown to this FIG. 4 (A). 22 is discharged. At this time, the provided side gap Z is smaller than the inner diameter of the guide portion 3, and the contents present above the movement valve 4 through the gap between the guide portion 3 and the movement valve 4 are located above the movement valve 4. Since the tip space 23 hardly flows, the quantitativeness of the discharge amount is further improved.

  In the state shown in FIG. 4B, the discharge port 22 is closed by being fitted to the fitting projection 43, but the discharge portion is excluded except for the fitting between the discharge port 22 and the fitting projection 43. An interval is maintained between the discharge chamber wall surface 33 b that is the inner surface of 33 and the moving valve 4. Among these intervals, in particular, it is functionally important that the balancing gap Y is maintained between the illustrated upper end of the overhang portion 33 a of the discharge portion 33 and the illustrated lower end of the base portion 41 of the moving valve 4. In this example, the balancing gap Y is 0.2 mm.

In the state where the balance gap Y does not exist and is in close contact, the movable valve 4 does not have a margin in the vertical direction in the drawing, so the movable valve 4 temporarily closes the discharge port 22 but the compressed elastic body 5. Due to the repulsive force, the moving valve 4 may be displaced upward in the figure, and the discharge port 22 cannot be closed stably, and the contents may leak.
On the other hand, in the state in which the balancing gap Y is maintained as described above, there is a margin in the vertical direction in the figure corresponding to the balancing gap Y, and the repulsive force of the elastic body 5 in the upward direction in the figure. In addition, the downward force in the figure acting on the movement valve 4 by pressurization of the container body 1 is balanced, thereby preventing the displacement of the movement valve 4 and effectively preventing leakage.

  Similarly, in order to prevent the displacement of the moving valve 4, a side gap Z is also maintained between the inner peripheral surface of the overhang portion 33 a in the discharge portion 33 and the outer peripheral surface of the small diameter portion 42 of the moving valve 4. . In this example, the lateral gap Z is 0.4 to 0.6 mm obtained by adding 0.2 to 0.4 mm corresponding to the diameter of the elastic body 5 to 0.2 mm as the balancing gap Y. Has been.

  Next, a discharge mechanism according to the second embodiment shown in FIG. In the following description, differences from the first embodiment will be mainly described. Also, the symbols in the figure will be described using the same symbols as in the first embodiment, except for a part.

The discharge mechanism of the second embodiment is mainly used when the contents are relatively high viscosity of 300 mPa · s or more, and the discharge mechanism of the first embodiment is difficult to move the contents and cannot be applied. Used. According to the experimental results described later, it has been confirmed that stable discharge is impossible when the content has a viscosity of 100 mPa · s or less, and good discharge is achieved at 1000 mPa · s or more.
The greatest difference from the discharge mechanism of the first embodiment is that a slit 35 through which the contents can pass is provided on the side surface of the main body 31 in the guide 3 as shown in FIG. is there. As in the first embodiment, the slit 35 is provided on the side surface of the cylindrical main body 31 over the entire dimension in the illustrated vertical direction every 60 ° in the circumferential direction.

  As in the first embodiment, the guide portion 3 of this embodiment has a stopper portion 32 that restricts the movement of the moving valve 4 toward the storage chamber 11 by contact. The stopper portion 32 is formed integrally with the main body portion 31 so as to be passed in a “Y” shape with respect to one end side end portion of the main body portion 31. Also in this embodiment, a central inflow hole 32 a is provided at the intersection portion of the “Y” shape, and the contents can flow into the guide portion 3 from here.

  In the present embodiment, the main body portion 31 and the stopper portion 32 are integrally formed, so that the appearance is also integral. The inflow opening 34 and the slit 35 are also integrated. Accordingly, it can be said that the slit 35 formed on the side surface side of the guide portion 3 in the inflow opening 34 is extended downward in the drawing.

  Further, in this embodiment, the guide portion 3 is formed smaller than the cross-sectional dimension of the discharge chamber 21, and a gap 12 through which contents can flow is provided between the inner wall 22 of the discharge portion and the side surface of the guide portion 3. It is done. As a result, as shown in FIG. 5, in the discharge chamber 21, the contents pass through the inflow opening 34 and the slit 35 of the guide portion 3, pass through the inside of the guide portion 3, and are discharged from the discharge port 22.

As in the first embodiment, the moving valve 4 in the present embodiment moves inside the guide portion 3 and closes the discharge port 22. In the first embodiment, the container body 1 is moved by the pressure difference generated across the movement valve 4 by pressurization of the container body 1, but in this embodiment, the container body 1 is pressurized in the discharge chamber 21. It is different to move on the flow of the resulting contents.
The shape of the moving valve 4 in this embodiment is different from that in the first embodiment, and no fitting projection 43 is provided. As shown in FIG. 5B, the small diameter portion 42 is illustrated. Although the discharge port 22 is supposed to be closed by covering the lower end surface, the present invention is not limited to this and can be implemented in various forms.

  In order to discharge the contents in the present embodiment, first, the storage container is turned upside down from the state shown in FIG. In this state, the discharge mechanism is in the state shown in FIG.

  Next, when the container body 1 is pressed and pressurized while the cap 6 is removed, the content starts to be discharged from the discharge port 22 in response to the pressurization, and the flow of the content from the storage chamber 11 toward the discharge port 22 flows. appear. This flow passes through the inside of the guide portion 3 through the inflow opening 34 and the slit 35 of the guide portion 3 in the discharge chamber 21, and at the same time, passes through the central inflow hole 32 a of the guide portion 3. It also flows into the space above the illustrated movement valve 4 inside the portion 3. In response to the flow of the contents, the moving valve 4 starts to move downward in the figure. Finally, as shown in FIG. 5B, when the small-diameter portion 42 of the moving valve 4 and the discharge port 22 come into contact, the discharge port 22 is closed, and the discharge of the contents ends. Thereby, a substantially constant amount of contents can be taken out from the discharge port 22.

  Then, when the pressure applied to the container main body 11 is eliminated, and the force pressing the moving valve 4 downward in the figure does not work, the elastic body 5 tends to extend, and the moving valve 4 moves upward in the figure. Then, the state returns to the state of FIG. Also in this embodiment, since the moving valve 4 is forcibly returned to the original state by the elastic body 5 as in the first embodiment, the moving valve 4 is surely returned.

Here, the inventor of the present application made a prototype of the discharge mechanism according to the first embodiment and the second embodiment described above, and conducted the following test.
In the test method, a storage container made of polyethylene and having a capacity of 100 ml was filled with 90 g of each of the five types of specimens (contents) shown in Table 1 and then discharged according to the first and second examples. A set of mechanisms was attached and five discharges were performed, and the discharge amount of each time was measured. And the average value of the discharge amount of each time was computed for every set. For specimens other than water, commercially available dimethyl silicone oil was used to keep the viscosity constant.

  The results for the first example are shown in Table 2. When the viscosity was 100 mPa · s or less, a fixed amount could be discharged, but when the viscosity was 1000 mPa · s or more, no discharge was possible.

  The results for the second example are shown in Table 3. When the viscosity was 50 mPa · s or less, the entire content was discharged without stopping at the first discharge. Further, when the viscosity was 100 mPa · s, the discharge amount was not stable at all. When the viscosity is 1000 mPa · s or more, stable ejection can be obtained.

  From the above results, the discharge mechanism according to the first embodiment is suitable when the contents have a relatively low viscosity, and the discharge mechanism according to the second embodiment is when the contents have a relatively high viscosity. It was confirmed that it was suitable for.
