Description
[Technical Field]
[0001] The present invention relates to a measured container. [Background technology]
[0002] Conventionally, as shown in Patent Document 1 below, for example, a measuring container has been known which comprises a container body having a body formed to be elastically deformable, a cap body which is attached to the mouth of the container body and has a discharge hole for the content liquid formed therein, a bottomed cylindrical measuring tube member provided inside the cap body, and a pipe which is provided inside the measuring tube member and extends downward from the top wall of the cap body, and in which a communication hole is formed in the measuring tube member which connects the inside of the container body with the inside of the measuring tube member. In this measuring container, the liquid content in the container body is supplied through a communicating hole into the measuring tube member and measured, and then the body is elastically deformed radially inward to increase the internal pressure in the body, thereby pressurizing the measuring tube member through the communicating hole, and the liquid content in the measuring tube member is passed through a pipe and discharged from the discharge hole.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-232777 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the conventional measuring container has a problem in that it is difficult to discharge the liquid contained in the measuring cylindrical member when the remaining amount is small.
[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a measuring container that can discharge the liquid contained in the measuring cylindrical member with a small amount remaining. [Means for solving the problem]
[0006] The measuring container of the present invention comprises a container body formed to be elastically deformable and having a body portion extending in the vertical direction; a cap body formed in a cylindrical shape with a top, attached to the mouth of the container body and having a discharge hole for the content liquid formed in the top wall; a measuring cylinder member formed in a cylindrical shape with a bottom and provided inside the cap body; and a pipe provided inside the measuring cylinder member and extending downward from the top wall of the cap body, wherein a communication hole is formed in the measuring cylinder member to communicate between the inside of the container body and the inside of the measuring cylinder member, and the communication hole opens in the measuring cylinder member at a portion located above the upper surface of the bottom wall of the measuring cylinder member, The pipe is composed of a first split cylinder portion and a second split cylinder portion that are split around the pipe axis, the first split cylinder portion is formed integrally with the top wall of the cap body, the second split cylinder portion is formed integrally with the bottom wall of the measuring cylinder member, and the lower end opening edge of the first split cylinder portion is close to the upper surface of the bottom wall of the measuring cylinder member. .
[0007] The communicating hole of the measuring cylinder opens into a portion of the measuring cylinder that is positioned above the upper surface of the bottom wall of the measuring cylinder. Therefore, when the measuring container is, for example, inverted, and the liquid in the container body is supplied into the measuring cylinder through the communicating hole, and then the measuring container is returned to the upright position, the liquid accumulates in the portion of the measuring cylinder that is positioned below the communicating hole, thereby being measured. At this time, the lower opening of the pipe is immersed in the liquid. The body is elastically deformed radially inward, increasing the internal pressure of the body, thereby pressurizing the measuring cylinder through the communicating hole. The liquid in the measuring cylinder then enters the pipe from the lower opening through a small gap between the remaining edge of the lower opening of the pipe and the upper surface of the bottom wall of the measuring cylinder, and is then discharged from the discharge hole. Since a portion of the lower end opening edge of the pipe abuts against or is formed integrally with the upper surface of the bottom wall of the measuring tube member, for example, when assembling the measuring container, the remaining portion of the lower end opening edge of the pipe can be easily brought close to the upper surface of the bottom wall of the measuring tube member without having to determine the relative positions of the measuring tube member and the pipe in the vertical direction with high precision, and even without having to design a large gap between the lower end opening of the pipe and the upper surface of the bottom wall of the measuring tube member to take into account manufacturing errors of each part, communication between the inside of the pipe and the inside of the measuring tube member can be reliably established when assembling the measuring container. As a result, it is possible to suppress an increase in manufacturing costs and discharge the liquid contained in the measuring cylinder member with a small amount remaining.
[0011] Since the pipe is composed of a first split cylinder portion formed integrally with the top wall of the cap body and a second split cylinder portion formed integrally with the bottom wall of the measuring cylinder member, the size of the gap between the lower end opening edge of the first split cylinder portion and the upper surface of the bottom wall of the measuring cylinder member can be determined easily and with high precision.
[0012] A gas-liquid mixing chamber located between the discharge hole and the upper end opening of the pipe, and an air supply passage communicating the gas-liquid mixing chamber with the inside of the measuring cylinder member may be provided on the top wall of the cap body.
[0013] Since a gas-liquid mixing chamber and an air supply passage are provided on the top wall of the cap body, the liquid content in the measuring cylinder member that has entered the pipe from its lower end opening as described above reaches the gas-liquid mixing chamber, and the air in the headspace in the measuring cylinder member that is located above the communication hole reaches the gas-liquid mixing chamber through the air supply passage, so that the liquid content and air can be mixed in the gas-liquid mixing chamber and discharged in a mist form from the discharge hole. [Effects of the Invention]
[0014] According to this invention, the liquid contained in the measuring cylinder member can be discharged with a small amount remaining. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0016] A measuring container according to a first embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the measuring container 1 according to this embodiment includes a container body 11, a cap body 12, a measuring cylinder member 13, and a pipe .
[0017] The container body 11 is formed in a cylindrical shape with a bottom, and the cap body 12 is formed in a cylindrical shape with a top. The container body 11 and the cap body 12 are disposed coaxially with a common axis O. Hereinafter, the direction along the common axis O will be referred to as the vertical direction, the top wall 15 side of the cap body 12 along the common axis O will be referred to as the upper side, and the bottom side of the container body 11 will be referred to as the lower side. When viewed from the vertical direction, the direction intersecting the common axis O will be referred to as the radial direction, and the direction going around the common axis O will be referred to as the circumferential direction.
[0018] The container body 11 has a mouth 11a and a body 11b that extend in the vertical direction. The body 11b is formed so as to be elastically deformable in the radial direction. The container body 11 contains, for example, a cosmetic product such as cosmetic oil, or a seasoning.
[0019] The cap body 12 has a top wall 15 and a peripheral wall 16, and is attached to the mouth portion 11a. The peripheral wall 16 is fitted to the exterior of the mouth portion 11a. The top wall 15 closes the upper end opening of the mouth portion 11a. The top wall 15 is formed with an attachment tube 15a that protrudes downward. The attachment tube 15a is disposed coaxially with the common axis O. The top wall 15 is formed with a discharge hole 17 for the content liquid. The discharge hole 17 is provided radially inward of the attachment tube 15a.
[0020] In the illustrated example, a topped cylindrical discharge tube 18 that protrudes upward is formed on the top wall 15. The discharge tube 18 is disposed coaxially with the common axis O. A discharge hole 17 is formed in the top wall of the discharge tube 18. The discharge hole 17 opens obliquely upward. Hereinafter, the radial direction in which the discharge hole 17 is open will be referred to as the front side, the opposite side will be referred to as the rear side, and the direction perpendicular to the front-rear direction will be referred to as the left-right direction.
[0021] A lid 27 is connected to the cap body 12 via a hinge portion 26. The lid 27 is formed in a cylindrical shape with a top and releasably covers the upper surface of the top wall 15 of the cap body 12. The hinge portion 26 connects the rear ends of the cap body 12 and the lid 27 to each other. The cap body 12, the hinge portion 26, and the lid 27 are integrally formed. A seal tube 27a protruding downward is formed on the top wall of the lid 27 and is detachably fitted to the discharge tube 18.
[0022] The measuring cylinder member 13 is formed in a cylindrical shape with a bottom, and is provided inside the cap body 12. The upper part of the measuring cylinder member 13 is fitted into the mounting cylinder 15a of the cap body 12. A slit 13a that opens upward and penetrates radially is formed at the rear end of the upper end of the measuring cylinder member 13. A vertical protrusion 15b formed on the inner circumferential surface of the mounting cylinder 15a is fitted into the slit 13a. The vertical protrusion 15b is formed at the rear end of the inner circumferential surface of the mounting cylinder 15a, protrudes forward, and extends in the vertical direction.
[0023] A communication hole 21 that communicates between the inside of the container body 11 and the inside of the measuring cylinder member 13 is formed in the measuring cylinder member 13. The communication hole 21 opens in the measuring cylinder member 13 at a portion located above the upper surface of the bottom wall 22 of the measuring cylinder member 13. As shown in Figures 1 and 2, the front end of the lower part of the measuring cylinder member 13 is recessed rearward over the entire length in both the vertical and horizontal directions. The front end of the connecting portion between the upper and lower parts of the measuring cylinder member 13 forms a step facing the vertical direction. A communication hole 21 is formed in this step. The communication hole 21 is provided over the entire area of the step. The communication hole 21 is open in the vertical direction.
[0024] The pipe 14 is provided inside the measuring cylinder member 13 and extends downward from the top wall 15 of the cap body 12. The pipe 14 is separate from the cap body 12 and the measuring cylinder member 13. The pipe 14 is made of a material that is softer than the cap body 12 and the measuring cylinder member 13. The pipe 14 may also be formed integrally with the cap body 12. The upper end of the pipe 14 is attached to the top wall 15 of the cap body 12. In the illustrated example, the central axis (hereinafter referred to as the pipe axis) L of the pipe 14 is spaced forward from the common axis O. The pipe axis L and the common axis O are positioned at the same position in the left-right direction. The upper end of the pipe 14 is fitted into the discharge tube 18.
[0025] Here, the top wall 15 of the cap body 12 is provided with a gas-liquid mixing chamber 23 located between the discharge hole 17 and the upper end opening of the pipe 14, and an air supply passage 24 that connects the gas-liquid mixing chamber 23 with the inside of the measuring cylinder member 13. The gas-liquid mixing chamber 23 and the air supply passage 24 are provided inside the discharge cylinder 18. Inside the discharge cylinder 18, the upper end of the pipe 14 is fitted into the front part, and the air supply passage 24 is provided at the rear part. The air supply passage 24 extends in the vertical direction. The upper end opening of the pipe 14 and the discharge hole 17 face each other in the vertical direction, with the gas-liquid mixing chamber 23 passing through.
[0026] A portion of the lower end opening edge of the pipe 14 abuts against or is formed integrally with the upper surface of the bottom wall 22 of the measuring cylinder member 13, and the remaining portion is close to the upper surface of the bottom wall 22 of the measuring cylinder member 13. A small vertical gap is provided between the remaining portion of the lower end opening edge of the pipe 14 and the upper surface of the bottom wall 22 of the measuring cylinder member 13, allowing the content liquid to pass through.
[0027] In this embodiment, a plurality of protrusions 25 that abut against the lower end opening edge of the pipe 14 are formed on the upper surface of the bottom wall 22 of the measuring cylinder member 13. A portion of the lower end opening edge of the pipe 14 abuts against the plurality of protrusions 25, and the remaining portion is close to the upper surface of the bottom wall 22 of the measuring cylinder member 13. A plurality of protrusions 25 are provided along the front-to-rear direction. The protrusions 25 are provided over the entire length in the left-to-right direction on the upper surface of the bottom wall 22. The protrusions 25 extend continuously in the left-to-right direction. When viewed from the left-to-right direction, the protrusions 25 have a triangular shape with the base located on the upper surface of the bottom wall 22 and the apex located at the upper end. The apexes of the plurality of protrusions 25 abut against the lower end opening edge of the pipe 14.
[0028] Next, the operation of the measuring container 1 will be described.
[0029] First, the measuring container 1 is placed in an inverted position, for example, and the liquid content in the container body 11 is supplied into the measuring cylinder member 13 through the communication hole 21. When the measuring container 1 is then returned to the normal position, the liquid content is measured by being collected in the portion of the measuring cylinder member 13 that is located below the communication hole 21. At this time, the lower end opening of the pipe 14 is immersed in the liquid content. Then, the lid 27 is rotated upward about the hinge portion 26 to open the discharge hole 17, and the barrel portion 11b of the container body 11 is elastically deformed radially inward to increase the internal pressure of the barrel portion 11b, thereby pressurizing the inside of the measuring cylinder member 13 through the communication hole 21, causing the content liquid in the measuring cylinder member 13 to enter the pipe 14 from its lower end opening through the small gap between the remaining part of the lower end opening edge of the pipe 14 and the upper surface of the bottom wall 22 of the measuring cylinder member 13, and reach the gas-liquid mixing chamber 23, and also causing the air in the head space within the measuring cylinder member 13, which is located above the communication hole 21, to reach the gas-liquid mixing chamber 23 through the air supply passage 24. As a result, the content liquid and air are mixed in the gas-liquid mixing chamber 23 and discharged from the discharge hole 17 in the form of a mist.
[0030] As described above, according to the measuring container 1 of this embodiment, a portion of the lower end opening edge of the pipe 14 abuts against the upper surface of the bottom wall 22 of the measuring tube member 13. Therefore, for example, when assembling the measuring container 1, the remaining portion of the lower end opening edge of the pipe 14 can be easily brought close to the upper surface of the bottom wall 22 of the measuring tube member 13 without having to determine the relative positions of the measuring tube member 13 and the pipe 14 with high precision. In addition, when assembling the measuring container 1, it is possible to reliably establish communication between the inside of the pipe 14 and the inside of the measuring tube member 13 without having to design a large gap between the lower end opening of the pipe 14 and the upper surface of the bottom wall 22 of the measuring tube member 13, taking into account manufacturing errors of each part. As a result, it is possible to discharge the liquid contained in the measuring cylindrical member 13 with a small amount remaining, while suppressing an increase in manufacturing costs.
[0031] Since a plurality of protrusions 25 that abut against the lower end opening edge of the pipe 14 are formed on the upper surface of the bottom wall 22 of the measuring cylinder member 13, it is possible to easily obtain a measuring container 1 that can discharge the content liquid in the measuring cylinder member 13 with little remaining liquid.
[0032] The top wall 15 of the cap body 12 is provided with a gas-liquid mixing chamber 23 and an air supply passage 24, so that the liquid content in the measuring cylinder member 13 that has entered the pipe 14 from its lower end opening as described above reaches the gas-liquid mixing chamber 23, and the air in the head space in the measuring cylinder member 13 located above the communicating hole 21 reaches the gas-liquid mixing chamber 23 through the air supply passage 24, and the liquid content and air can be mixed in the gas-liquid mixing chamber 23 and discharged in a mist form from the discharge hole 17.
[0033] Next, a measuring container 2 according to a second embodiment will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted, and only the differences will be described.
[0034] In this embodiment, the pipe 31 is divided about the pipe axis L into a first split cylindrical portion 32 and a second split cylindrical portion 33.
[0035] The first split cylinder portion 32 is formed integrally with the top wall 15 of the cap body 12. It extends downward from the front of the peripheral edge of the lower opening of the discharge cylinder 18 on the lower surface of the top wall 15. The edge of the lower opening of the first split cylinder portion 32 is close to the upper surface of the bottom wall 22. First locking protrusions 32a are formed on both left and right ends of the first split cylinder portion 32, extending continuously over the entire length in the up and down direction. The first locking protrusions 32a are formed in the shape of a plate with the front and back surfaces facing the front-to-rear direction.
[0036] The second split cylinder portion 33 is formed integrally with the bottom wall 22 of the measuring cylinder member 13. The second split cylinder portion 33 extends upward from the upper surface of the bottom wall 22 and is fitted into the discharge cylinder 18. Second locking projections 33a extending continuously over the entire length in the up-down direction are formed on both left-right ends of the second split cylinder portion 33. The second locking projections 33a are hook-shaped when viewed from the up-down direction and sandwich the first locking projections 32a in the front-to-rear direction.
[0037] As described above, according to the measuring container 2 of this embodiment, a portion of the lower end opening edge of the pipe 31 is formed integrally with the upper surface of the bottom wall 22 of the measuring cylinder member 13, so that, as in the above embodiment, it is possible to discharge the liquid content in the measuring cylinder member 13 with a small amount remaining while suppressing an increase in manufacturing costs. Since the pipe 31 is composed of a first split cylinder portion 32 formed integrally with the top wall 15 of the cap body 12 and a second split cylinder portion 33 formed integrally with the bottom wall 22 of the measuring cylinder member 13, the size of the gap between the lower end opening edge of the first split cylinder portion 32 and the upper surface of the bottom wall 22 of the measuring cylinder member 13 can be determined easily and with high precision.
[0038] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0039] For example, the front end portion of the lower portion of the measuring cylinder member 13 does not have to be recessed rearward. It is not necessary to form the slit 13a in the measuring cylinder member 13 and the vertical protrusion 15b in the mounting cylinder 15a. The top wall 15 of the cap body 12 does not necessarily need to be provided with the gas-liquid mixing chamber 23 and the air supply passage 24 .
[0040] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
