Description

  The present invention relates to a container with a measuring cap.

  2. Description of the Related Art Conventionally, a container with a measuring cap including a container main body in which liquid is stored and a measuring cap capable of measuring liquid from the inside of the container main body has been widely used. Specifically, the measuring cap includes a cap body that is attached to the mouth of the container body. The cap main body is formed with a measuring space for storing and measuring the liquid supplied from the inside of the container main body, and is provided with a communication portion that connects the inside of the container main body and the measuring space. Then, when the container main body is pressed (that is, squeezed) with a finger or the like, the liquid inside the container main body is stored in the measurement space via the communication portion.

  As such a container with a measuring cap, for example, as disclosed in Patent Document 1, by pressing the container body, the container is communicated with the measuring cap through a dispensing pipe extending downward from the bottom of the measuring cap. In some cases, liquid is stored in a measuring cap and measured. In addition, as disclosed in Patent Document 2, there is one to which a double-structure container body is applied. In the double container body, the outer layer is more rigid than the inner layer. Thereby, at the time of squeezing, the outer layer and the inner layer are deformed inside the container body, and when squeezing is finished and the pressing force to the container body is released, the outside air flows into the space between the inner layer and the outer layer. The outer layer is restored to its original shape by elasticity.

Japanese Utility Model 06-064054 JP 2017-36057 A

  By the way, when measuring through an extraction tube as disclosed in Patent Document 1, when the container body is stopped from being pressed, the container body is temporarily poured from the inside of the container body when it returns to its original shape due to elasticity. The excess liquid or air that has been discharged flows back into the container body, so that depending on the contents of the container, oxidative degradation may occur or it may be unfavorable for hygiene. Further, as disclosed in Patent Document 2, in a container with a measuring cap having a double-structured container body, a check valve that restricts the flow of liquid in one direction from the inside of the container body to the measuring space is communicated. May be provided in the section. As a result, the liquid and air once poured out from the inside of the container body can be prevented from flowing back into the container body, so that the oxidative deterioration of the liquid inside the container body can be suppressed, or the liquid can be sanitized. Can be kept. However, since the mouth of the container main body to which the measuring cap is attached is difficult to deform during squeeze, there is a risk that the liquid remaining inside the container main body without being poured out may increase.

  Therefore, the present invention relates to appropriately pouring out liquid while suppressing backflow of liquid and air into the inside of the container body in a container with a measuring cap.

  In order to solve the above-described problem, an aspect of the present invention is a container with a measuring cap including a double-structured container main body in which liquid is accommodated and a measuring cap capable of measuring the liquid. A cap body mounted on the mouth of the container body, the cap body protruding from the peripheral edge of the bottom wall portion to the opposite side of the container body, covering the opening of the mouth of the container body And a communication part that communicates the space on the opposite side of the container body with respect to the inside and bottom wall part of the container body, and a liquid flow from the inside of the container body to the bottom wall. A check valve is provided for restricting in one direction toward the space opposite to the container body relative to the container, and a measuring space for storing and weighing the liquid supplied from the inside of the container body through the communicating portion is provided at the bottom. It is defined by the wall, peripheral wall and check valve. It has a first cylindrical part projecting toward the container body side, and the first cylindrical part is formed with an inlet for injecting the liquid contained in the container body, When the container with a cap is not in use, when the container with the measuring cap is in a posture in which the measuring cap is positioned vertically above the container main body, the inlet is separated from the liquid surface inside the container main body. It relates to a container with a measuring cap.

  As described above, according to the container with a measuring cap of the present invention, the liquid can be appropriately poured out while suppressing the backflow of the liquid and air into the container body.

  Embodiments of the present invention relate to a container with a measuring cap. Specifically, a container 1 with a measuring cap according to an embodiment of the present invention is a container with a measuring cap provided with a double-structured container main body and a measuring cap capable of measuring a liquid contained in the container main body. It is.

<Configuration of container with measuring cap>
First, with reference to FIG.1 and FIG.2, the structure of the container 1 with a measuring cap which concerns on embodiment of this invention is demonstrated.

  1 and 2 are a side sectional view and a side partial sectional view showing a container 1 with a measuring cap, respectively. Specifically, FIG. 1 shows a container 1 with a measuring cap when it is not used, and FIG. 2 shows a container 1 with a measuring cap after the start of use (that is, when it is not in use). Yes. In addition, unused of the container 1 with a measurement cap means that the supply of the liquid 9 from the inside of the container main body 2 to the measurement space 5 has never been performed.

  In addition, in this specification, in order to understand easily, the direction which goes to the measurement cap 3 from the container main body 2 is called an upper direction. Here, since the container 1 with the measuring cap can take various postures when used by the user, the upward direction used in the following description does not necessarily mean the vertically upward direction. 1 to 4, the container 1 with a measuring cap is shown in a posture in which the measuring cap 3 is positioned vertically above the container body 2. On the other hand, the direction opposite to the upward direction is referred to as the downward direction. In the container 1 with the measuring cap of FIG. 1, the measuring cap 3 side is upward, and the container body 2 side is downward.

  As shown in FIG. 1, the container 1 with a measuring cap includes a container body 2 and a measuring cap 3.

  The container body 2 has a double structure, and a liquid 9 is accommodated therein. Various liquids can be applied as the liquid 9, and for example, edible liquids such as edible oil, soy sauce, dressing or sauce are applied.

  Specifically, as shown in FIG. 1, the container main body 2 includes a main body portion 21 having an inner layer 21 a and an outer layer 21 b and a mouth portion 22 connected to the main body portion 21. The mouth portion 22 has a substantially cylindrical shape. The inner layer 21 a and the outer layer 21 b extend downward from the lower end portion of the mouth portion 22 to form the body portion and the bottom portion of the container body 2. The inner layer 21a and the outer layer 21b are separated from each other at the side of the main body 21, and a space 23 is formed between the inner layer 21a and the outer layer 21b. The liquid 9 is accommodated in the inner layer 21a. The container body 2 is made of resin, for example, and is manufactured by blow molding. As the resin forming the container body 2, for example, polyolefin resins such as polyethylene and polypropylene, polyethylene terephthalate, polyamide, and ethylene / vinyl alcohol copolymer resin are preferably used. In addition, the container main body 2 should just have a double structure, The container main body of a well-known double structure can be widely used as the container main body 2. FIG.

  As will be described later, in the container 1 with the measuring cap, the liquid 9 is measured by pressing the container body 2 with a finger or the like (that is, the container body is squeezed). When squeezing, the outer layer 21 b and the inner layer 21 a are deformed inside the container body 2. Here, the outer layer 21b is more rigid than the inner layer 21a, and when deformed, it easily returns to its original shape due to elasticity. The space 23 between the inner layer 21a and the outer layer 21b communicates with the outside of the container body 2 through, for example, holes (not shown) formed in the mouth portion 22, the body portion, the bottom portion, and the like of the container body 2. . Therefore, when the squeeze is completed and the pressing force to the container body 2 is released, the outside air 21b returns to its original shape due to elasticity by the outside air flowing into the space 23 between the inner layer 21a and the outer layer 21b. Therefore, the container 1 with a measuring cap can be mounted stably.

  The measuring cap 3 is a cap capable of measuring the liquid 9 accommodated in the container body 2.

Specifically, the upper cylindrical portion 331 corresponds to a portion of the first member 310 that protrudes upward from the center side of the upper bottom wall portion 311. For example, as shown in FIGS. 1 and 2, the upper tubular portion 331 is disposed coaxially with the peripheral wall portion 32 inside the peripheral wall portion 32. The internal space of the upper tubular portion 331 is connected to the internal space of the lower tubular portion 332.

  In the upper cylindrical portion 331, a discharge port 331a for the liquid 9 is formed. The discharge port 331 a is an opening that discharges the liquid 9 supplied to the inside of the upper cylindrical portion 331 to the outside of the upper cylindrical portion 331. At the time of squeezing, the liquid 9 supplied from the inside of the container body 2 via the communication portion 33 is discharged toward the measurement space 5 from the discharge port 331a.

  Here, as shown in FIG. 2, the discharge port 331 a is formed at a side portion at the distal end portion of the upper cylindrical portion 331, and an upper cylindrical shape is formed at the distal end (that is, the upper end) of the upper cylindrical portion 331. It is preferable that a top plate portion 331b extending in a direction intersecting with the projecting direction of the portion 331 is formed. Thereby, as will be described later, it is possible to prevent the liquid 9 from being discharged from the discharge port 331a with an excessive force.

  The measuring space 5 is defined by the bottom wall portion 31, the peripheral wall portion 32, and the check valve 7 described above. Specifically, the measuring space 5 is a space defined by the upper part of the upper bottom wall part 311, the inner peripheral part of the peripheral wall part 32, and the upper part of the check valve 7. Here, as shown in FIGS. 1 and 2, it is preferable that the indication line 8 indicating the upper end of the measuring space 5 is displayed on the inner peripheral portion or the outer peripheral portion of the peripheral wall portion 32. Thereby, the user can visually recognize the range of the measurement space 5. Further, from the viewpoint of measuring the liquid 9 in various volumes, it is more preferable that one or more scale lines (not shown) are displayed below the instruction line 8 on the inner peripheral portion or the outer peripheral portion of the peripheral wall portion 32. Further, from the viewpoint of making it easy to visually recognize the instruction line 8 or the scale line, the member forming the peripheral wall portion 32 (specifically, the first member 310) is preferably transparent or translucent.

  The lower cylindrical portion 332 protrudes from the bottom wall portion 31 toward the container body 2 side. Specifically, the lower cylindrical portion 332 corresponds to a portion of the second member 320 that protrudes downward from the center side of the lower bottom wall portion 312. For example, as shown in FIGS. 1 and 2, the lower cylindrical portion 332 is disposed coaxially with the mounting portion 34 inside the mounting portion 34. Further, the lower cylindrical portion 332 is disposed coaxially with the upper cylindrical portion 331.

  In the lower cylindrical portion 332, an inlet 332a for the liquid 9 is formed. The injection port 332a is an opening into which the liquid 9 accommodated in the container body 2 is injected. Specifically, as shown in FIGS. 1 and 2, the injection port 332 a is formed at the distal end (that is, the lower end) of the lower cylindrical portion 332. Further, as will be described later, for example, the injection port 332a is preferably positioned closer to the bottom wall portion 31 than the tip (that is, the lower end) of the attachment portion 34, as shown in FIGS. At the time of squeeze, the liquid 9 accommodated in the container body 2 is injected into the communication portion 33 through the injection port 332a.

  Here, in the container 1 with the measuring cap according to the present embodiment, the container 1 with the measuring cap is in a posture in which the measuring cap 3 is positioned vertically above the container body 2 when the container 1 with the measuring cap is not used. In this case, the injection port 332a is separated from the liquid surface of the liquid 9 inside the container body 2. Thereby, as will be described in detail later, it is possible to appropriately dispense the liquid 9.

  The communicating portion 33 has a reverse flow that restricts the flow of the liquid 9 in one direction from the inside of the container main body 2 to the space opposite to the container main body 2 (specifically, the measuring space 5) with respect to the bottom wall portion 31. A stop valve 7 is provided. Specifically, the check valve 7 is disposed between the upper cylindrical portion 331 and the lower cylindrical portion 332 in the communication portion 33 and is sandwiched in the vertical direction by the first member 310 and the second member 320. ing. As shown in FIGS. 1 and 2, for example, the check valve 7 includes a valve receiver 7a having an opening and a valve body 7b that covers the opening.

Further, the valve body 7b is elastically deformed so as to rotate around the connection portion with the valve receiver 7a when a force is applied in the direction from the inside of the container body 2 toward the measuring space 5, and the valve receiver 7a. It will be in the state away from the opening (that is, the state where the check valve 7 is opened). At the time of squeeze, the check valve 7 is open, and the internal space of the upper tubular portion 331 and the internal space of the lower tubular portion 332 are in communication. On the other hand, when the squeeze is not performed, the check valve 7 is closed, and the internal space of the upper cylindrical portion 331 and the internal space of the lower cylindrical portion 332 are blocked by the check valve 7. Yes.

  The lid 40 covers the measuring space 5 of the cap body 30. Specifically, the lid body 40 has a substantially cylindrical shape having a bottom portion on one side, is connected to the cap body 30 via the hinge portion 50, and the hinge portion 50 is connected to the cap body 30. It is pivotable about the center. By rotating the lid 40, the lid 40 is opened as shown in FIG. 2 (that is, the measuring space 5 is exposed), and the lid 40 is closed as shown in FIG. (That is, the state in which the measurement space 5 is covered with the lid 40) can be changed.

  Specifically, as shown in FIGS. 1 and 2, the lid body 40 includes a liquid seal portion 41, a measuring portion seal portion 42, and a protruding portion 43.

  The liquid seal portion 41 is fitted into the upper tubular portion 331 and seals the discharge port 331a. Specifically, the liquid seal portion 41 protrudes from the center side on the inner surface of the bottom portion of the lid body 40. The liquid seal portion 41 has a substantially cylindrical shape, and as shown in FIGS. 1 and 2, the outer periphery of the distal end portion (that is, the upper end portion) of the upper tubular portion 331 in a state where the lid body 40 is closed. It is fitted to the part. Thereby, the discharge port 331a is sealed by the inner peripheral portion of the liquid seal portion.

It is fitted to the part. Thereby, the opening 32 a of the peripheral wall portion 32 is sealed by the outer peripheral portion of the measuring portion seal portion 42.

  The protruding portion 43 is a portion that protrudes from the outer peripheral portion of the lid body 40 and is a portion on which the user's finger or the like is hung when the user opens the lid body 40.

<Operation of container with measuring cap>
Then, with reference to FIGS. 1-4, operation | movement of the container 1 with a measuring cap which concerns on embodiment of this invention is demonstrated.

  Below, especially when the container 1 with a measuring cap is unused, operation | movement of the container 1 with a measuring cap when starting use is demonstrated.

  3 and 4, the state of the container 1 with the measuring cap when the liquid 9 is discharged into the measuring space 5 and when the liquid level 9b of the liquid 9 stored in the measuring space 5 reaches the instruction line 8 respectively. It is shown.

  As shown in FIG. 1, when the container 1 with a measuring cap is not used, when the container 1 with the measuring cap is in a posture in which the measuring cap 3 is positioned vertically above the container body 2, the inlet 332 a 2 is away from the liquid surface 9a of the liquid 9 inside. Specifically, a space where the liquid 9 does not exist partially exists inside the inner layer 21 a of the container body 2. The space is formed of a gas such as air. And when the container 1 with a measurement cap is made into the attitude | position in which the measurement cap 3 is located vertically upwards with respect to the container main body 2, the space formed of gas, such as air, is located in the upper side in the inside of the container main body 2. . When the container 1 with a measuring cap is in the above-described posture when the container 1 with a measuring cap is not used, the liquid level 9a of the liquid 9 inside the container body 2 is positioned below the lower end of the lower cylindrical portion 332. . Therefore, the inlet 332 a of the lower cylindrical portion 332 is separated from the liquid surface 9 a of the liquid 9 inside the container body 2 and is not immersed in the liquid 9.

  When starting the use of the container 1 with the measuring cap, the user opens the lid 40, and puts the container 1 with the measuring cap in a posture in which the measuring cap 3 is positioned vertically above the container main body 2. Start squeeze 2 Thereby, the check valve 7 is opened, and the internal space of the upper tubular portion 331 and the internal space of the lower tubular portion 332 are in communication with each other. Further, the inner layer 21 a is deformed inside the container main body 2 by pressing the container main body 2. Thereby, first, gas is discharged to the outside through the communicating portion 33 from the space inside the container body 2 where the upper liquid 9 does not exist. Thus, the liquid level 9a of the liquid 9 inside the container body 2 rises as the gas is released from the inside of the container body 2 to the outside. Then, the liquid surface 9a of the liquid 9 inside the container body 2 reaches the injection port 332a.

  Thereafter, the inner layer 21 a is further deformed inside the container body 2, and the liquid 9 inside the container body 2 is supplied to the measurement space 5 via the communication portion 33. Specifically, as shown in FIG. 3, the liquid 9 contained in the container body 2 is injected into the lower cylindrical portion 332 through the injection port 332a, and the lower cylindrical portion 332 and the upper cylindrical portion 332 are then injected. It passes through the inside of the tubular portion 331 and is discharged from the discharge port 331a toward the measurement space 5. At this time, the position in the vertical direction of the liquid surface 9a of the liquid 9 inside the container body 2 is maintained in a state where it coincides with the position in the vertical direction of the inlet 332a.

  In the supply of the liquid 9 via the communication part 33, the liquid 9 sent from the inlet 332 a to the inside of the upper cylindrical part 331 flows along the projecting direction of the upper cylindrical part 331. Here, as described above, it is preferable that the discharge port 331a is formed at the side portion at the distal end portion of the upper tubular portion 331, and the top plate portion 331b is formed at the distal end of the upper tubular portion 331. Thereby, the liquid 9 sent to the inside of the upper cylindrical part 331 collides with the top-plate part 331b, and is then discharged from the discharge outlet 331a. Therefore, it is possible to suppress the liquid 9 from being discharged from the discharge port 331a with an excessive momentum.

  The liquid 9 discharged from the discharge port 331a toward the measurement space 5 is stored in the measurement space 5. By continuing the squeeze of the container body 2, the liquid level 9 b of the liquid 9 stored in the measurement space 5 rises. Then, the liquid surface 9b of the liquid 9 stored in the measuring space 5 reaches the instruction line 8 as shown in FIG. At this time, the user ends the squeeze. Thereby, the discharge of the liquid 9 from the discharge port 331a is completed, and the measurement of the liquid 9 is completed. The user may end the squeeze before the liquid level 9b of the liquid 9 stored in the measurement space 5 reaches the instruction line 8 and complete the measurement of the liquid 9. When the measurement of the liquid 9 is completed, the check valve 7 is closed by the end of the squeeze, and the internal space of the upper cylindrical portion 331 and the internal space of the lower cylindrical portion 332 are blocked by the check valve 7. Thereby, it is possible to suppress the liquid 9 and air once poured out from the inside of the container body 2 from flowing back into the container body 2. Therefore, the oxidative deterioration of the liquid 9 inside the container body 2 can be suppressed, or the liquid 9 can be kept hygienic.

  When the liquid 9 measured by the measuring cap 3 is poured out from the measuring cap 3, the user tilts the container 1 with the measuring cap from a posture in which the measuring cap 3 is positioned vertically above the container body 2. Specifically, the user tilts the container 1 with the measuring cap so that the extraction part 32b is positioned vertically lower than the other part of the peripheral part of the opening 32a of the peripheral wall part 32. Thereby, the liquid 9 stored in the measurement space 5 including the inside of the upper cylindrical portion 331 is poured out from the dispensing portion 32 b of the peripheral wall portion 32.

  After the liquid 9 has been dispensed, the user closes the lid 40. Thereby, the container 1 with a measuring cap will be in the state shown in FIG. As described above, in the container 1 with the measuring cap, the air once poured out from the inside of the container main body 2 can be prevented from flowing back into the container main body 2, so that the container as shown in FIG. After the supply of the liquid 9 from the inside of the main body 2 to the measurement space 5 once, the volume of the space in the container main body 2 where the upper liquid 9 does not exist becomes smaller than that when not used. Yes.

  Here, as described above, the lid 40 is preferably formed with the liquid seal portion 41 that is fitted to the upper cylindrical portion 331 and seals the discharge port 331a. Thereby, the discharge port 331a can be sealed by the inner peripheral portion of the liquid seal portion 41 in a state where the lid 40 is closed. Therefore, when the user does not intend to use the container 1 with the measuring cap, the liquid 9 is unintentionally discharged into the measuring cap 3 from the discharge port 331a due to the force applied to the container body 2. This can be suppressed.

  Moreover, it is preferable that the measurement part seal part 42 fitted to the surrounding wall part 32 is formed in the cover body 40 as mentioned above. Thereby, the opening 32 a of the peripheral wall portion 32 can be sealed by the outer peripheral portion of the measuring portion seal portion 42 in a state where the lid 40 is closed. Therefore, when the user does not intend to use the container 1 with the measuring cap, the liquid 9 can be prevented from leaking from the inside of the measuring cap 3 due to the force applied to the container body 2. .

  After the dispensing of the liquid 9 is finished, when the container 1 with the measuring cap is used again, the user opens the lid 40 and the measuring cap 3 is placed vertically upward with respect to the container main body 2. The squeeze of the container main body 2 is started again in the position in which it is positioned. At this time, the vertical position of the liquid surface 9a of the liquid 9 inside the container body 2 is in a state coincident with the vertical position of the inlet 332a. Then, as the squeeze of the container body 2 is started, the supply of the liquid 9 to the measuring space 5 via the communication portion 33 is started as shown in FIG. Thereafter, the liquid 9 is weighed and dispensed in the same manner as described above.

  As described above, in the container 1 with a measuring cap according to the present embodiment, the lower cylindrical portion 332 having the injection port 332a is projected from the bottom wall portion 31 toward the container body 2 side. In addition, when the container 1 with the measuring cap is not used, when the container 1 with the measuring cap is in a posture in which the measuring cap 3 is positioned vertically above the container main body 2, the inlet 332 a is a liquid inside the container main body 2. 9 away from the liquid level 9a. Further, since the check valve 7 is provided in the communication portion 33, the air once extracted from the inside of the container body 2 is prevented from flowing back into the container body 2. Thereby, after starting the use of the unused container 1 with the measuring cap, the state in which the vertical position of the liquid surface 9a of the liquid 9 inside the container body 2 coincides with the vertical position of the inlet 332a. The liquid 9 accommodated in the container main body 2 can be measured by the measuring cap 3 while maintaining the above. Therefore, even if the mouth portion 22 of the container main body 2 is difficult to deform, the liquid 9 that remains in the container main body 2 without being poured out can be reduced. Therefore, the liquid 9 can be appropriately poured out while suppressing the liquid 9 and air from flowing back into the container body 2.

  Furthermore, in the container 1 with the measuring cap according to the present embodiment, as described above, after the liquid 9 is once supplied from the inside of the container main body 2 to the measuring space 5, the upper liquid in the container main body 2 is supplied. The volume of the space in which 9 does not exist can be reduced as compared with the unused space. Thereby, since the ratio of the air with respect to the liquid 9 in the container main body 2 can be made small, the oxidation of the liquid 9 can be suppressed.

  As described above, when the container 1 with a measuring cap is not used, a space where the liquid 9 does not exist partially exists inside the container body 2. Here, from the viewpoint of increasing the volume of the liquid 9 accommodated in the container main body 2 when the container 1 with a measuring cap is not used, the distance between the inlet 332a and the bottom wall portion 31 can be made as short as possible. preferable. On the other hand, it is preferable to make the distance between the inlet 332a and the bottom wall portion 31 as long as possible from the viewpoint of appropriately reducing the amount of the liquid 9 that remains in the container body 2 without being poured out. Therefore, in order to achieve both of the above viewpoints, for example, it is preferable that the injection port 332a be positioned closer to the bottom wall portion 31 than the distal end (that is, the lower end) of the attachment portion 34. Furthermore, by positioning the injection port 332a closer to the bottom wall portion 31 than the tip of the attachment portion 34, the measuring cap 3 can be placed so that the lower end portion of the attachment portion 34 is grounded over the entire circumference. . Therefore, for example, in the manufacturing process, the measuring cap 3 can be easily and stably aligned, and the measuring cap 3 can be easily transported.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can make various modifications or application examples within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.

  For example, the shapes of the container body 2 and the measuring cap 3 are not limited to the example described above. For example, the shapes of the main body portion 21 and the mouth portion 22 of the container main body 2 may be a rotationally symmetric shape or may not be a rotationally symmetric shape. Further, for example, the shapes of the bottom wall portion 31, the peripheral wall portion 32, the communication portion 33, and the attachment portion 34 of the cap body 30 of the measuring cap 3 may be a rotationally symmetric shape or may not be a rotationally symmetric shape. Good. For example, the shape of the liquid seal part 41 and the measurement part seal part 42 of the lid body 40 of the measurement cap 3 may be a rotationally symmetric shape or may not be a rotationally symmetric shape. Further, for example, a portion extending from the upper end of the peripheral wall portion 32 to the inside of the peripheral wall portion 32 and facing the bottom wall portion 31 may be provided on the upper portion of the cap body 30 of the measuring cap 3. For example, the spout of the liquid 9 may be formed by penetrating the part up and down. For example, the discharge port 331a may be formed at the tip (that is, the upper end) of the upper cylindrical portion 331.

  In addition, for example, in the above description, the communication portion 33 has the upper cylindrical portion 331 and the lower cylindrical portion 332. However, the upper cylindrical portion 331 may be omitted from the configuration of the communication portion 33. In that case, the discharge port which discharges the liquid 9 supplied from the inside of the container main body 2 toward the measurement space 5 is formed in the connection part of the communication part 33 and the bottom wall part 31, for example.

  Further, for example, each drawing shows an example in which each of the inner layer 21a and the outer layer 21b of the body portion 21 of the container body 2 is a single layer, but both or one of the inner layer 21a and the outer layer 21b is a multilayer. May be.

  For example, in the above description, an edible liquid is illustrated as the liquid 9 accommodated in the container body 2, but other liquids (for example, liquid cosmetics such as cosmetic liquids) may be applied as the liquid 9. .

  In addition, for example, in the above description, the check valve 7 includes the valve receiver 7a having an opening and the valve body 7b that covers the opening. However, the configuration of the check valve 7 is not particularly limited to the above example. The check valve 7 only needs to have a function of restricting the flow of the liquid 9 in one direction from the inside of the container body 2 toward the measuring space 5.

  For example, the material of the container main body 2 and the measuring cap 3 is not particularly limited, and may be formed of a resin other than the resin exemplified above. Moreover, the measurement cap 3 may be comprised by the some member which consists of a mutually different material.

  Further, for example, each component of the measuring cap 3 may be formed by the same member or may be formed by separate members. For example, in the measuring cap 3, the cap main body 30 and the lid body 40 may be formed of the same member or may be formed of different members. In addition, when the cap main body 30 and the lid body 40 are respectively formed by separate members, the lid body 40 may be attached by being screwed to the cap main body 30. For example, in the above description, the cap body 30 is formed of the first member 310 and the second member 320, but the entire cap body 30 may be formed of the same member. The cap body 30 may be formed of three or more members. Further, when the cap body 30 is formed of a plurality of members, the position of the boundary between the members in the cap body 30 is not particularly limited.
