  By the way, it is common that the conventional metering container including patent document 1 accommodates the content whose viscosity is comparatively low. For example, in the metering and dispensing container of Patent Document 1, when the contents having a relatively low viscosity are used, the contents flow smoothly through the liquid inflow hole. The weighing in the weighing chamber is completed simply by making it happen. However, in the case of liquid contents such as sauces and liquids that have a relatively high viscosity, it becomes difficult for the contents to pass through the liquid inflow hole, so that it takes time until the measurement is completed, and the usability is impaired. Is assumed.

  An object of the present invention is to solve such problems, and in particular, it is possible to dispense a liquid content with a relatively high viscosity in a fixed amount, and a metering and dispensing container that is also easy to use. The purpose is to provide.

  Hereinafter, one embodiment of a metering container according to the present invention will be described with reference to FIGS. Note that the relationship between “upper” and “lower” in this specification and the like refers to a direction in a state where the container body (reference numeral 1) is upright as shown in FIG.

  The metering and dispensing container shown in FIG. 1 includes a container body 1, a dispensing member 2 (referred to as “pouring cap 2” in the present embodiment), and an intermediate member 3 (in this embodiment, “inner plug member 3”). And the pipe 5 and the lid 5.

  The container body 1 has a disc-shaped bottom portion 1a, a cylindrical shape, a barrel portion 1b connected to the outer edge portion of the bottom portion 1a, and a cylindrical shape having a smaller diameter than the barrel portion 1b, and has an upper opening. The mouth part 1c connected with the upper end part of the trunk | drum 1b in the state, and the external thread part 1d provided in the outer peripheral surface of the mouth part 1c are provided. The container body 1 of the present embodiment is made of synthetic resin, and the body portion 1b has flexibility. In addition, various contents can be stored in the container body 1, but liquid contents having a relatively high viscosity are particularly preferable. In order to prevent the contents from overflowing from the mouth portion 1c when the pouring cap 2 or the inner plug member 3 is attached, the amount of the contents accommodated in the container body 1 is poured as shown in FIG. It is assumed that the head space can be made with the cap 2 and the like attached.

  The dispensing cap 2 includes a cylindrical lower outer peripheral wall 2a that surrounds the mouth 1c, an upper outer peripheral wall 2b that is connected to the upper end of the lower outer peripheral wall 2a and has a smaller diameter than the lower outer peripheral wall 2a, A ceiling wall 2c connected to the upper end portion of the outer peripheral wall 2b, a cylindrical pouring tube 2d provided on the outer edge side of the center portion of the ceiling wall 2c, and a circular hole located at the upper end of the pouring tube 2d (Pour-out port) 2e. Further, a female screw portion 2f that fits the male screw portion 1d is provided on the inner peripheral surface of the lower outer peripheral wall 2a. The pouring cap 2 is directly engaged with the container body 1 by screwing the female screw portion 2f with the male screw portion 1d. Retained. In addition, when hold | maintaining the extraction | pouring cap 2 in the container main body 1, you may use means other than a screw like undercut, for example.

  The inner plug member 3 is connected to the inner cylindrical portion 3a extending from above the upper end portion of the mouth portion 1c toward the inner side of the container body 1 and the lower end portion of the inner cylindrical portion 3a inside the mouth portion 1c. A donut plate-like bottom plate portion 3b, an outer cylindrical portion 3c connected to the outer edge portion of the bottom plate portion 3b and extending toward the upper end portion of the mouth portion 1c, and radially outward from the upper outer peripheral surface of the outer cylindrical portion 3c And a flange portion 3d extending toward the surface. Further, as shown in the partial enlarged cross-sectional view of FIG. 1, a step portion 3e extending radially inward is provided at the upper end portion of the inner cylindrical portion 3a. A cylindrical protruding portion 3f is provided. And the slit-shaped hole (introduction port) 3g provided at intervals in the circumferential direction is provided on the outer peripheral surface of the protrusion 3f. Here, the inner plug member 3 is sandwiched between the upper end portion of the mouth portion 1c and the lower end portion of the upper outer peripheral wall 2b in a state where the dispensing cap 2 is attached to the container body 1. A space (measuring chamber) K is defined between the upper outer peripheral wall 2b and the top wall 2c of the pouring cap 2 and the inner cylindrical portion 3a, the bottom plate portion 3b, and the outer cylindrical portion 3c of the inner plug member 3. It is formed.

  The pipe 4 has an elongated cylindrical shape, and is fitted and held in the inner cylindrical portion 3a so as to abut against the stepped portion 3e. Here, the opening (one end side opening) 4a above the pipe 4 communicates with the introduction port 3g. The pipe 4 extends downward in a state where the pipe 4 is fitted and held in the inner cylindrical portion 3a, and the lower opening (the other end opening) 4b is located in the vicinity of the bottom 1a. .

  The lid 5 includes a top wall 5a located above the top wall 2c, and a lid outer peripheral wall 5b extending downward from the outer edge of the top wall 5a. A cylindrical seal wall 5c is provided on the lower surface of the top wall 5a so as to contact the inner peripheral surface of the extraction cylinder 2d and close the outlet 2e. Further, the lid outer peripheral wall 5b is provided with a hinge 5d that is integrally connected to the upper outer peripheral wall 2b. By opening the lid 5 by swinging the lid 5 around the hinge 5d, the spout 2e is opened. It can be opened. The lid 5 may be separated from the dispensing cap 2 and attached to the dispensing cap 2 by, for example, an undercut or a screw.

  In order to pour the contents from the metering pour container having such a configuration, as shown in FIG. 2, the body 1b is pressed in a state where the container main body 1 is upright. As a result, the content stored in the container body 1 is pressurized, the content enters the pipe 4 from the other end side opening 4b, and further passes through the one end side opening 4a and is introduced into the measuring chamber K. . Here, it is assumed that the body 1b is sufficiently pressed and the contents are accommodated in the measuring chamber K until it exceeds the introduction port 3g. Further, when the contents are introduced into the weighing chamber K, the lid 5 is opened as shown in order to allow the air in the weighing chamber K to escape to the outside so that the contents and air can be smoothly replaced. It is preferable.

  After the contents are stored in the measuring chamber K, as shown in FIG. 3, the pressure on the body 1b is released to restore the body 1b. When the body portion 1b is restored, the inner volume of the container body 1 is increased and the container body 1 is depressurized more than when pressed, so that the contents stored in the weighing chamber K beyond the inlet 3g are stored in the container body 1 Will be pulled back. That is, since only the contents accumulated below the introduction port 3g remain in the measuring chamber K, a fixed amount of contents can be measured.

  Thereafter, the container body 1 is inverted as shown in FIG. At this time, since the air in the head space moves to the bottom 1a side, the other end side opening 4b of the pipe 4 is located above the liquid level of the contents. When the body portion 1b is pressed in this state, the air in the head space is pressurized and enters the pipe 4 from the other end side opening 4b, passes through the one end side opening 4a, and passes through the introduction port 3g to the measuring chamber K. To be introduced. The air introduced into the measuring chamber K moves to the upper side of the measuring chamber K and pressurizes the measuring chamber K as shown in the figure, so that the contents stored in the measuring chamber K are poured into the pouring cylinder 2d. It can be poured out from the outlet 2e.

  Even if the dispensing of the contents is interrupted halfway and the container body 1 is erected as before, the contents remaining in the measuring chamber K do not return to the container body 1. That is, the body portion 1b is restored by the interruption of the contents. However, in the state where the container main body 1 is upright, the contents are stored below the inlet 3g. Only the air taken in from will enter. For this reason, if the container main body 1 is inverted again and the trunk | drum 1b is pressed, only the content remaining in the measurement chamber K can be poured out. As described above, according to the metering and dispensing container of the present embodiment, it is possible to dispense a fixed amount of content in small portions.

  When the amount of the content to be poured out may be smaller than the amount accommodated in the measuring chamber K, the content introduced into the measuring chamber K can be introduced into the inlet 3g by lightly pressing the barrel 1b. It may be kept so as not to exceed. Also in this case, as shown in FIG. 4, the contents introduced into the measuring chamber K can be poured out by pressing the barrel portion 1b with the container body 1 in an inverted state. In addition, if the container main body 1 and the inner plug member 3 are formed of a transparent (or translucent) material, the amount of the contents introduced into the measuring chamber K can be visually observed. Accordingly, for example, if a scale or the like indicating the amount of the content introduced into the measuring chamber K is provided, the content can be measured using the scale as a clue, so that it is less than the amount accommodated in the measuring chamber K. Even in this case, it is possible to dispense a fixed amount of content.

  In addition, if the contents adhere around the spout 2e after the contents are poured out, there is a problem in terms of hygiene. However, in the metering container of this embodiment, the contents are poured out. After that, since air is taken in from the spout 2e by the restoration of the body portion 1b, the contents attached around the spout 2e at that time can be pulled back to the measuring chamber K and the container body 1. With regard to this point, when repeated examination was performed using the metering and dispensing container according to the present invention including the present embodiment, if the size of the spout 2e is 4 mm or less, sufficient pull back performance can be obtained even in various use environments. It was confirmed that

  On the other hand, when containing a high-viscosity content, if the size of the spout 2e is reduced, it will not be possible to pour unless the body 1b is pressed strongly, and it will take time to pour out. Usability will be impaired. With regard to this point, as a result of repeated investigations using various measuring and dispensing containers according to the present invention, when the viscosity of the content is 2.0 Pa · s or less, it is not necessary to press so strongly in the dispensing, It was also confirmed that there was no problem with the time required for the extraction. Further, if the viscosity of the contents is too low, the contents are immediately poured out when the container body 1 is inverted. If the viscosity is 0.2 Pa · s or more, the container body 1 is inverted. However, the content was not immediately poured out from the spout 2e, and it was confirmed that it was excellent in terms of usability. As described above, according to the metering and dispensing container according to the present invention, even a relatively high-viscosity liquid content that is difficult to dispense in a conventional manner is quantitative and easy to use. Can be issued.

  Next, another metering container according to the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the part which is common in embodiment mentioned above, and description is abbreviate | omitted.

  The measuring and dispensing container of the present embodiment includes a dispensing cap 6 in place of the previously described dispensing cap 2. Further, the dispensing cap 6 is provided with a valve body 7 and a holder 8 for holding the valve body 7 on the dispensing cap 6. Further, a lid body 9 is provided instead of the lid body 5 described above.

  The pouring cap 6 includes a cylindrical lower outer peripheral wall 6a that surrounds the mouth 1c, an upper outer peripheral wall 6b that is connected to the upper end of the lower outer peripheral wall 6a and has a smaller diameter than the lower outer peripheral wall 6a, A ceiling wall 6c that is connected to the upper end portion of the outer peripheral wall 6b and is inclined upward as it goes inward in the radial direction, a valve body holding wall 6d that forms an annular shape at the center of the top wall 6c, and an upper end of the valve body holding wall 6d And a circular hole (outlet) 6e. A female screw portion 6f that fits the male screw portion 1d is provided on the inner peripheral surface of the lower outer peripheral wall 6a.

  The valve body 7 is a so-called slit valve. As shown in the partially enlarged sectional view of FIG. 5, the annular base portion 7a and the outer edge portion rise upward from the base portion 7a, while the central portion. Is provided with a thin-shaped valve body portion 7b that is curved downward. In addition, a cut (slit) is provided at the center of the valve body 7b. Here, the valve body 7 is formed of a soft material such as rubber or elastomer, and the valve body portion 7b is elastically deformable. For this reason, although the slit is normally closed, when pressure is applied to the valve body portion 7b, the valve body portion 7b can be opened as shown in FIG.

  The holder 8 generally has a configuration in which a portion having a donut plate shape and an annular portion extending upward from the inner edge of the donut plate portion are combined. The holder 8 is fitted and held on the lower surface of the pouring cap 6, and as shown in FIG. 5, the valve body 7 is connected to the pouring cap 6 with the valve body portion 7b exposed from the pouring port 6e. Can be held between.

  The lid 9 includes a top wall 9a located above the top wall 6c, and a lid outer peripheral wall 9b extending downward from the outer edge of the top wall 9a. The central portion of the top wall 9a is curved downward and is configured to lightly push the valve body portion 7b downward when the lid body 9 is closed. That is, when the lid body 9 is closed, the slit of the valve body 7 is slightly opened, so that a problem that the contents attached to the valve body 7 are solidified and the slit is not opened can be effectively prevented. An annular seal wall 9c that surrounds and contacts the valve body holding wall 6d is provided on the lower surface of the top wall 9a. The lid outer peripheral wall 9b is provided with a hinge 9d that is integrally connected to the upper outer peripheral wall 6b.

  Also in the weighing and dispensing container configured in this way, as shown in FIG. 6, when the body 1b is pressed in a state where the container body 1 is upright, the contents stored in the container body 1 are pressurized. And introduced into the measuring chamber K via the pipe 4. The contents stored in the measuring chamber K beyond the inlet 3g when the body 1b is pressed are pulled back to the container body 1 when the body 1b is restored as shown in FIG. Only the contents accumulated below the introduction port 3g can be left in the measurement chamber K in the same manner as the measurement dispensing container described.

  Thereafter, as shown in FIG. 8, the body 1b is pressed in a state where the container body 1 is inverted. As a result, the air in the container body 1 is introduced into the measuring chamber K from the introduction port 3g via the pipe 4, and the measuring chamber K is pressurized by this air to open the valve body portion 7b. The contents that have been made can be poured out.

  When the pressure on the body 1b is released after the contents are poured out, the pressure in the measuring chamber K is reduced and the valve body 7b is immediately closed. That is, since the liquid content of the contents is improved, it is less likely that the periphery of the spout 6e remains dirty even when a liquid content having a relatively high viscosity is poured out. Furthermore, in this embodiment, since air is taken in from the spout 6e (valve body 7b) by the restoration of the body 1b, the contents adhering to the periphery of the spout 6e and the valve body 7b at that time are also measured. It can be pulled back to K or the container body 1 and can be used more sanitarily.

I have. The container main body 10 of the present embodiment is also made of a synthetic resin like the container main body 1 described above, and the trunk portion 10b has flexibility.

  The pipe 11 has an annular shape and is shaped so as to be bent in a side view, and the upper opening (one-end-side opening) 11a is inside the mouth 10c and is the central axis of the container body 10 Located on O. Moreover, the opening part (other end side opening part) 11b under the pipe 11 is located in the outer edge vicinity of the bottom part 10a. In addition, the direction in which the other end side opening 11b opens with respect to the central axis O is opposite to the direction in which a spout 15d described later opens.

  The intermediate member 12 has a cylindrical shape, and includes a cylindrical wall 12a that extends along the central axis O and that fits and holds the pipe 11 at the lower end. A slit 12b extending in the vertical direction is provided at the upper end of the cylindrical wall 12a, and an opening (introduction port) 12c is provided at a position aligned with the lower end of the slit 12b. Further, a bottom wall portion 12d extending outward in the radial direction is provided at the lower end portion of the cylindrical wall 12a, and the outer edge portion of the bottom wall portion 12d extends upward inside the mouth portion 10c. An existing inner annular wall 12e is provided. A flange portion 12f extending radially outward is provided at the upper end portion of the inner annular wall 12e, and an outer annular wall 12g surrounding the upper end portion of the mouth portion 10c is provided at the lower surface of the flange portion 12f. ing.

And the outer peripheral wall 12j surrounding the substantially whole area in the height direction of the opening | mouth part 10c is provided in the outer edge part of the flange part 12f. Further, an engagement convex portion 12k that protrudes radially outward is provided on the upper outer peripheral surface of the outer peripheral wall 12j.

  Such an intermediate member 12 is held by screwing the female screw portion 12h into the male screw portion 10d of the container body 10 in a state where the pipe 11 is fitted and held in the cylindrical wall 12a.

  The pouring member main body 14 includes a cylindrical side wall 14a having substantially the same diameter as the outer peripheral wall 12j. A claw portion 14b having a shape that fits the engaging convex portion 12k is provided at the lower portion of the side wall 14a. An upper annular wall 14c extending so as to incline with respect to the central axis O is provided on the upper side of the side wall 14a, and a male screw portion 14d is provided on the outer peripheral surface of the upper annular wall 14c.

  The content pouring cap 15 surrounds the upper annular wall 14c, and has an annular holding wall 15b provided with an internal thread portion 15a corresponding to the external thread portion 14d on the inner peripheral surface, and a top wall 15c connected to the upper end portion of the annular holding wall 15b.

The outer peripheral wall 15f is provided with a lid wall 15h that is openably and closably connected via a hinge 15g. The inner surface of the lid wall 15h is connected to the inner peripheral surface of the dispensing cylinder 15e when the lid wall 15h is closed. A seal cylinder 15j that comes into liquid-tight contact is provided.

  The pouring member main body 14 and the content pouring cap 15 formed in this way are engaged by engaging the female screw part 15a with the male screw part 14d and engaging the claw part 14b with the engaging convex part 12k. It is held by the member 12. In other words, the pouring member 13 composed of the pouring member main body 14 and the content pouring cap 15 is indirectly held in the mouth portion 10 c of the container main body 10 through the intermediate member 12. In addition, the attachment order of each member demonstrated so far is an example, Comprising: It is not restricted to this.

  In the weighing and dispensing container according to the present embodiment assembled in this way, a space (metering chamber) K is defined inside the intermediate member 12, the dispensing member main body 14, and the contents dispensing cap 15. . Further, in the measuring chamber K in the present embodiment, as shown in FIG. 9, a predetermined amount of content is measured in a space located below the introduction port 12 c in a state where the container main body 10 is upright, as will be described later. This space is referred to in this specification as the weighing space K1. In addition, a space (a space located above the introduction port 12c) excluding the measurement space K1 in the measurement chamber K is referred to as a head space K2. Here, the volume of the head space K2 is larger than the volume of the measuring space K1.

  In order to pour the contents from the metering pour container having such a configuration, first, as shown in FIG. 9, the body portion 10b is pressed in a state where the container main body 10 is upright. As a result, the contents stored in the container body 10 are pressurized, the contents enter the pipe 11 from the other end side opening 11b located near the outer edge of the bottom 10a, and further pass through the one end side opening 11a to form a cylinder. It passes through the shaped wall 12a and is introduced into the measuring chamber K from the inlet 12c. Here, it is assumed that the body portion 10b is sufficiently pressed and the contents are accommodated in the measuring chamber K until it exceeds the introduction port 12c. Further, when the contents are introduced into the measuring chamber K, the lid wall 15h is opened as shown in order to allow the air in the measuring chamber K to escape to the outside so that the contents and air can be smoothly replaced. It is preferable.

  After the contents are accommodated in the measuring chamber K, the pressure on the body 10b is released to restore the body 10b. When the body portion 10b is restored, the inner volume of the container body 1 is increased and the container body 1 is depressurized more than when pressed, so that the contents stored in the measuring chamber K beyond the inlet 12c are stored in the container body 10. Will be pulled back. That is, since only the contents accumulated below the introduction port 12c remain in the measuring chamber K, a fixed amount of contents can be measured.

  Thereafter, as shown in FIG. 10, the container body 10 is tilted and inverted so that the spout 15 d faces downward, and the body portion 10 b is pressed. At this time, since the air in the container body 10 moves to the bottom 10a side, the opening 11b on the other end side of the pipe 11 is located above the liquid level of the contents. The other end side opening portion 11b of the present embodiment opens to the opposite side to the direction in which the spout 15d opens with respect to the central axis O, and the container body 10 is placed so that the spout 15d faces downward. When tilted, the other end side opening 11b is positioned further upward. For this reason, the other end side opening part 11b can be reliably located above the liquid level of the contents. When the body part 10b is pressed in this state, the air in the container body 10 is pressurized and enters the pipe 11 from the other end side opening part 11b, and further passes through the cylindrical wall 12a through the one end side opening part 11a. Then, it is introduced into the measuring chamber K from the inlet 12c. Thereby, since the measurement chamber K is pressurized by the introduced air, the contents stored in the measurement chamber K can be poured out from the spout 15d. Further, as described above, since the volume of the head space K2 is larger than the volume of the measuring space K1, the introduction port 12c is located closer to the liquid level of the contents stored in the measuring chamber K as shown in FIG. Is also located above. Here, when the contents accommodated in the measuring chamber K are divided and poured out, if the introduction port 12c is immersed in the remaining contents of the measuring chamber K, the body portion 10b is restored. In doing so, it is conceivable that the contents of the measuring chamber K will flow backward from the inlet 12c to the container body 10 and the amount of the weighed contents will change, but in this embodiment there is no such risk.
