Description

Measuring container {MEASURING CONTAINER}

The present invention relates to a weighing vessel.

This application claims priority based on Japanese Patent Application No. 2014-241177 for which it applied to Japan on November 28, 2014, and uses the content here.

For example, a cap attached to a container body containing liquid contents such as a softener and liquid detergent generally has a measuring function and has a transparent engagement wall portion so that the measured contents can be visually recognized from the outside. Caps are widely used. In such a metering cap, a metering line or the like is formed as a relief by printing or molding in the metering tube portion located inside the engaging wall portion.

As a mode in which a metering cap is attached to the mouthpiece of the container body, a mode in which the metering cap is screwed onto the mouthpiece is common in order to prevent liquid contents from leaking during transportation or handling. However, in a container in which a metering cap is screwed together, if a finger is wet with water during handling or if contents such as detergent adhere to the finger, the finger easily slips, making it difficult to open and close the metering cap.

Further, as a form of attaching the cap to the mouth portion of the container body, a form of fitting the cap to the mouth portion has also been proposed.

For example, a container in which an engagement concave portion is formed at the lower end of the outer wall surface of a taper-shaped mouthpiece that is reduced in diameter toward the upper end, and an engagement convex portion that fits with the engagement concave portion is formed at the lower end of the inner wall surface of the cap. (Patent Document 1, for example). In the container, by pressing inward the central portion of the opposing side walls of the cap fitted into the neck portion in the vertical direction, the engagement concave portion and the engagement convex portion are disengaged, and in that state, the cap is moved upward. Remove the cap from the mouthpiece by lifting it up.

However, in the container described above, a two-step operation is required to remove the cap, and it is difficult to remove the cap when the finger is slippery due to adhesion of water, detergent, or the like.

Further, a cap portion having an octagonal planar shape of the lower end portion and a cap having a rectangular planar shape of the lower end portion are provided, a first rib is formed on an outer wall surface of the mouthpiece portion above the lower end portion, and a first rib is formed on the inside of the cap portion. A container in which a second rib is formed on the wall surface to be locked to the lower surface of the first rib when the cap is attached to the neck portion is exemplified (for example, Patent Literature 2). In the container, the first rib and the second rib are respectively disposed at positions corresponding to every other outer surface around the axial line among the eight outer surfaces of the lower end of the neck portion. When removing the cap, the cap mounted on the neck portion is rotated by only 1/8 rotation to release the fit between the first rib and the second rib, and in that state, the cap is lifted upward to separate it.

However, in the above container, force is required to rotate the cap having a rectangular lower end with respect to the mouthpiece having an octagonal flat lower end, so when the finger slips easily due to adhesion of water or detergent, the cap is removed. It is difficult to separate.

In addition, an engagement concave portion is formed on the outer wall surface of the neck portion having a tapered diameter reducing toward the upper end and having a rectangular planar shape, and an engagement convex portion that fits with the engagement concave portion is formed on the inner wall surface of the cap having a rectangular planar shape. A container is mentioned (for example, patent document 3). In the above container, when removing the cap, the cap attached to the neck portion is rotated to release the engagement of the engagement concave portion and the engagement convex portion, and in that state, the cap is lifted upward and separated.

However, in the container, force is required to rotate the cap having a rectangular planar shape with respect to the mouthpiece having a rectangular planar shape, so the cap is removed when the finger slips easily due to adhesion of water or detergent. It is difficult to do.

In addition, in the container of the type in which the cap is fitted, there is a problem in that the visibility of the measuring line from the outside in the radial direction is poor when a measuring cap having a measuring tube portion is used as the cap, making it difficult to measure the contents.

A bottom wall portion 16 having an inclined surface 16a is provided at the lower end of the inner cylinder wall 13, and spout ports 16b are formed unevenly on the bottom wall portion 16. That is, the spout 16b is formed unevenly on the inside of the mouth portion 9 . A pouring cylinder 17 is installed upright on the periphery of the pouring spout 16b in the bottom wall portion 16 .

Since the spout 16b is unevenly distributed in the bottom wall portion 16, the spout 17 standing upright around the spout 16b is also unevenly distributed in the inner cylinder wall 13. In the pouring cylinder 17, a slit-shaped opening 17b is formed in the longitudinal direction on the central axis C1 side of the bore portion 9 in the side wall thereof. In addition, the pouring cylinder 17 is cut in an oblique direction such that an inclined surface 17a is formed such that the upper end thereof is lowered toward the central axis C1.

In the nozzle inner cap 8, the inner cylinder wall 13 is inserted into the protruding cylinder part 7, and the screw part 11a of the outer cylinder wall 11 is screwed part 7a of the protruding cylinder part 7 of the container body 2. ), it is detachably attached to the projecting tube portion 7 of the container body 2 by being screwed together.

In addition, the nozzle inner plug 8 is formed with a cylindrical seal lip 15 extending downward from the lower surface of the connection wall 12 between the outer cylinder wall 11 and the inner cylinder wall 13. As a result, in a state where the nozzle cap 8 is attached to the protruding tube portion 7 of the container body 2 by screwing, the seal lip portion 15 is inserted into the opening of the protruding tube portion 7 without gaps. As a result, the opening of the protruding tube portion 7 is closed liquid-tight.

As shown in FIGS. 2A, 2B and 3A to 3C, the outer circumferential surface of the outer cylinder wall 11 is spaced at 180° intervals around the axis of the outer cylinder wall 11, that is, in a symmetrical position around the axis of the outer cylinder wall 11. (Symmetric position in the circumferential direction), a concave portion 11A is formed toward the inner circumferential surface in the form of a tongue when viewed from the front. The recess 11A is a portion along which the extension piece 21 of the metering cap 3 follows when the metering cap 3 is mounted on the nozzle inner cap 8.

A stepped wall portion 11B is formed at the edge of the recess 11A on the outer circumferential surface of the outer cylinder wall 11 .

As shown in FIG. 3A, the stepped wall portion 11B has a shape as if a part of a sine curve was cut out when viewed from the front, and extends in the vertical direction of the cylinder wall portion 10 on both sides of the bottom portion, It is also inclined in the rotation direction (circumferential direction) of the measuring cap 3.

In the recessed portion 11A of this example, the bottom of the stepped wall portion 11B when viewed from the front is located near the lower end of the outer cylinder wall 11. The distance between the bottom of the stepped wall portion and the lower end of the outer circumferential surface of the aperture portion when viewed from the front can be, for example, 5 to 20 mm. The width of the axial line of the upper end of the recess 11A is approximately 1/6 of the entire circumference of the outer circumferential surface of the outer cylinder wall 11, that is, the entire circumference of the outer circumferential surface of the aperture portion 9.

It is preferable that the axial width (length in the circumferential direction) of the upper end of the recess along the extension is in the range of 1/6 to 1/3 of the entire circumference of the outer circumferential surface of the neck portion.

In addition, when the recess along the extension and the recess along the engagement wall are connected, the width of the axial line of the upper end of the recess along the extension is the recess along the extension on the outer circumferential surface of the aperture. It means the distance around the axis between the boundary points of the edge of the recess and the edge of the recess along which the engagement wall part follows. For example, in this example, on both sides of the circumferential direction of the recess 11A in the outer circumferential surface of the aperture portion 9, the curved edge portion on the upper end side of the recess 11A and the recess 11C The distance around the axial line between the boundary points of the linear edge portions is taken as the width around the axial line of the upper end of the recess 11A.

It extends linearly in the vertical direction in the stepped wall portion 11B with respect to the rotation direction (circumferential direction) of the measuring cap 3, that is, in the direction orthogonal to the central axis C1, and tilts in the rotation direction. The inclination angle θ of the photograph portion (FIG. 3A) is preferably 40 to 70°, and more preferably 45 to 65°. If the inclination angle θ is equal to or greater than the lower limit value, the metering cap 3 can be more stably mounted on the nozzle cap 8. If the inclination angle θ is equal to or less than the upper limit value, the measuring cap 3 can be separated more easily.

Near the upper end of the portion other than the recess 11A on the outer circumferential surface of the outer cylinder wall 11, a recess 11C extending from one recess 11A to the other recess 11A is formed. . The recessed portion 11C is a portion along which the engagement wall portion 22 of the metering cap 3 follows when the metering cap 3 is mounted on the nozzle inner cap 8. The recess 11C is a part between the two recesses 11A and one side of the recess 11A (the left side in Fig. 3A) and the opposite side (the right side in Fig. 3A). Two are formed in The shape seen from the front of 11 C of recesses is a rectangular shape with a long axial circumference.

3-10 mm is preferable and, as for the length of the vertical direction of 11 C of recesses, 5-7 mm is more preferable.

As shown in Fig. 3B, in the portion of the recess 11C on the outer circumferential surface of the outer cylinder wall 11, there are convex lines protruding outward in the radial direction and extending in the rotation direction (circumferential direction) of the measuring cap 3. A first engagement convex portion 25 formed is formed.

The first engagement convex portion 25 has a circumferential length (length in the circumferential direction) of 15° to 20° around the axis of the outer cylinder wall 11 around the central axis C1 in plan view. It is formed to converge within the range of °.

As shown in FIGS. 4A to 4C , the measuring cap 3 includes a cylindrical weighing cylinder 18, a lid 19 closing an open end on one side of the measuring cylinder 18, and the weighing cylinder 18. When viewed from a plane protruding outward from the circumferential surface of the annular flange portion 20, two extension pieces 21 extending downward from the outer edge of the flange portion 20, and the flange portion 20 An engaging wall portion 22 extending downward from a portion other than the portion where the extension piece 21 is formed in the outer edge portion is provided. In this way, the measuring cap 3 has a cylindrical shape with a lid, and has a flange portion protruding outward at the center in the height direction. Outside of the extension piece 21 and the engaging wall portion 22 of the flange portion 20, a protruding portion protruding outward from the outer edge of the flange portion 20 may be formed.

In addition, a ring portion 23 protruding downward is formed on the inner periphery of the flange portion 20 .

A part of the lower end of the metering cylinder 18 is inserted into the cylinder wall 10 of the nozzle stopper 8 so as to surround the pouring cylinder 17.

On the portion between the two extension pieces 21 on the circumferential wall of the metering tube portion 18, as shown in FIG. 4C, a scale portion 24 having scale lines for measurement and numbers for displaying capacity is printed, It is formed by means such as engraving. This makes it possible to determine the amount of contents such as liquid injected from the opening 18a of the measuring cylinder 18 in a state where the measuring cap 3 is inverted.

The flange portion 20 covers the opening at the upper end of the cylinder wall portion 10 of the nozzle stopper 8 in the mouth portion 9 when the metering cap 3 is attached to the nozzle stopper 8.

The extension piece 21 is a tongue-shaped thin piece narrowed toward the lower end when viewed from the front, and its lower end 21a is curved when viewed from the front.

Two extension pieces 21 are formed at 180° intervals around the axis of the flange portion 20, that is, to be in a symmetrical position with respect to the central axis C1 when the measuring cap 3 is attached to the mouth portion 9. has been The two extension pieces 21 respectively follow the two recesses 11A in the outer circumferential surface of the cylinder wall portion 10 of the nozzle stopper 8 when the metering cap 3 is attached.

It is preferable that the width (length in the circumferential direction) around the axis of the upper end of the extension piece is converged within the range of 40 to 70 degrees centered on the central axis in plan view around the axis of the flange portion. When the metering cap is attached to the nozzle stopper, the central axis of the flange portion coincides with the central axis of the neck portion.

Further, when the extension piece and the engagement wall portion are integrally formed without being separated from each other, the width around the axis of the upper end of the extension piece is the circumference of the axis between the boundary points between the edge portion of the extension piece and the edge portion of the engagement wall portion on the outer surface of the extension piece. means distance. For example, in this example, a straight line between the curved edge portion of the upper end of the extension 21 and the engagement wall 22 on both sides of the extension 21 in the circumferential direction of the extension 21 on the outer surface of the extension 21. The distance around the axis between the boundary points of the edge portions of the image is taken as the width around the axis of the upper end of the extension piece 21.

It is preferable that the length of the extension piece in the up-down direction is 10-25 mm. In addition, the vertical length of an extension means the distance from the lower surface of a flange part to the lower end of an extension.

In this example, as shown in Fig. 2A, when the measuring cap 3 is attached and the lower end 21a of the extension 21 is aligned with the bottom of the stepped wall 11B when viewed from the front, the extension The lower end portion 21a of 21 is slightly separated from the stepped wall portion 11B. Thereby, when rotating the measuring cap 3, initial rotation can be performed more easily. The lower end portion 21a of the extension piece 21 contacts the stepped wall portion 11B when the measuring cap 3 is attached and rotated.

When the position of the lower end of the extension in the circumferential direction is aligned with the position of the bottom of the stepped wall when viewed from the front, when the lower end of the extension and the stepped wall are spaced apart, the lower end of the extension and the bottom of the stepped wall when viewed from the front The distance of is preferably 0.3 to 1.2 mm.

Further, in the present invention, when the lower end of the extension is aligned with the bottom of the stepped wall when viewed from the front, the lower end of the extension may be brought into contact with the stepped wall.

Further, in this example, the width of the extension piece 21 is narrower than the width of the recess 11A formed on the outer circumferential surface of the outer cylinder wall 11 of the nozzle inner plug 8. As a result, when the measuring cap 3 is attached, the side edge portion of the extension piece 21 above the lower end portion 21a is separated from the stepped wall portion 11B on both sides.

The engaging wall portion 22 is a rectangular thin piece with a length around the axis line longer than the length in the vertical direction when viewed from the front.

Two engagement wall portions 22 are formed at 180° intervals around the axis of the flange portion 20, that is, to be in a symmetrical position with respect to the central axis C1 when the metering cap 3 is attached to the bore portion 9. has been Both of the two extension pieces 21 are formed from one extension piece 21 to the other extension piece 21 . That is, the two extension pieces 21 and the two engaging wall portions 22 are integrally formed.

When the measuring cap 3 is mounted, the engagement wall portion 22 follows the two recesses 11C in the outer circumferential surface of the cylinder wall portion 10 of the nozzle stopper 8, respectively.

The lower end of the engaging wall portion 22 is located closer to the flange portion 20 than the lower end of the extension piece 21 . That is, the length of the engaging wall portion 22 in the vertical direction is shorter than the length of the extension piece 21 in the vertical direction. This makes it easier to visually recognize the graduations 24 when measuring the contents with the measuring cap 3 inverted.

3-10 mm is preferable and, as for the length of the vertical direction of the engagement wall part 22, 5-7 mm is more preferable. When the length of the engagement wall portion 22 in the vertical direction is equal to or greater than the lower limit, formation of the second engagement convex portion 26 described later is easy. When the length of the engagement wall portion 22 in the vertical direction is equal to or less than the upper limit value, the visibility of the scale portion 24 at the time of weighing the content becomes better.

A second engagement convex portion 26 is formed on the inner surface of the engagement wall portion 22 to engage the first engagement convex portion 25 of the outer cylinder wall 11 when the metering cap 3 is attached.

The second engagement convex portion 26 is formed on the inner surface of the engagement wall portion 22 below the first engagement convex portion 25 of the outer cylinder wall 11 when the measuring cap 3 is attached to the bore portion 9. It is formed to fit. The first engagement portion 27 is formed by the first engagement convex portion 25 and the second engagement convex portion 26 . When the measuring cap 3 is mounted, the first engagement convex portion 25 and the second engagement convex portion 26 of the first engagement portion 27 are engaged, so that the measurement cap 3 with respect to the caliber portion 9 Relative upward movement can be regulated. Thereby, it is possible to prevent the attached measuring cap 3 from unexpectedly coming off upward.

In the measuring container 1, it is preferable that elasticity is imparted to the engaging wall portion 22. This makes it possible to easily engage the first engagement convex portion 25 and the second engagement convex portion 26 of the first engagement portion 27 when the measuring cap 3 is attached.

(Manufacturing method)

As a method of manufacturing the bottom wall 4, the side wall 5, the shoulder portion 6, and the protruding cylinder portion 7 of the container body 2, for example, blow molding using an olefinic synthetic resin such as polyethylene, etc., integrally A molding method may be mentioned. As a manufacturing method of the nozzle plug 8 of the container main body 2, the method of integrally molding by injection molding using olefinic synthetic resins, such as polypropylene, is mentioned, for example. As a manufacturing method of the measuring cap 3, the method of integrally molding by injection molding using olefinic synthetic resins, such as polyethylene, is mentioned, for example.

In addition, the manufacturing method of the container body 2 and the measuring cap 3 is not limited to the method mentioned above.

(action effect)

Hereinafter, the separation operation, measurement operation, and attaching operation of the measurement cap 3 in the measurement container 1 will be described.

In the measuring container 1 before use, as shown in FIG. 2B, in a state where the contents are accommodated in the container body 2, the pouring cylinder 17 is turned upward, and the nozzle plug 8 is attached to the protruding cylinder part 7. do. Since the opening of the protruding tube portion 7 is liquid-tightly closed by the seal lip portion 15 of the nozzle plug 8, the threaded portion 7a of the protruding tube portion 7 and the threaded portion 11a of the nozzle plug 8 Liquid leakage through the screwed part of the is prevented.

In the state where the measuring cap 3 is attached to the nozzle plug 8 of the mouth part 9, as shown in Figs. 1 and 2A, the two extension pieces 21 of the measuring cap 3 are It follows the part of 11 A of recesses in the outer peripheral surface of the wall part 10. Further, the two engagement wall portions 22 of the measuring cap 3 follow the portion of the recess 11C in the outer circumferential surface of the cylinder wall portion 10. And the cylinder wall part 10 of the nozzle stopper 8 is clamped by each of these extension piece 21 and engagement wall part 22.

Further, in this state, the second engagement convex portion 26 formed on the metering cap 3 is engaged with the lower surface of the first engagement convex portion 25 formed on the outer circumferential surface of the aperture portion 9. Thereby, the relative upward movement of the measuring cap 3 with respect to the aperture part 9 is restricted.

To remove the measuring cap 3, first hold the top of the measuring cap 3 with your fingers, and slightly rotate the measuring cap 3 counterclockwise (clockwise) around the axis when viewed in plan. At this time, in the first engagement portion 27, the second engagement convex portion 26 slides on the lower surface of the first engagement convex portion 25, and the lower end 21a of the extension piece 21 of the measuring cap 3 ) contacts the stepped wall portion 11B of the nozzle cap 8. Further, when the measuring cap 3 is rotated, the engagement state of the first engagement convex portion 25 and the second engagement convex portion 26 is released, and the lower end portion 21a of the extension piece 21 is moved to the stepped wall portion 11B. ), a force for moving the extension piece 21 obliquely upward is applied. As a result, as indicated by arrow a in Fig. 5, the extension piece 21 is pushed up along the stepped wall portion 11B, and as a result, the metering cap 3 rotates and moves obliquely upward. The cap 3 can be easily removed.

In the measuring container 1, even if the measuring cap 3 is rotated clockwise (clockwise) around the axis when viewed in plan, the measuring cap 3 can be easily removed in the same manner.

Then, as shown in FIG. 4C, the metering cap 3 is inverted, and the container body 2 is tilted so that the tip of the pouring cylinder 17 of the nozzle inner cap 8 is directed downward to remove the contents in the container body 2. It is injected from the pouring port 16b through the pouring cylinder 17 into the metering cylinder 18. The injection amount of the contents into the measuring box 18 of the measuring cap 3 can be grasped by the scale 24 .

In the metering cap 3 when metering operation is performed, since the vertical length of the engaging wall portion 22 is short, the scale portion 24 is easily visible from between the extension pieces 21 and 21, and the metering tube portion 18 You can accurately determine the amount of content received in the.

After the measurement is finished and the contents are used, while aligning the position of the extension piece 21 with the part of the recess 11A in the outer circumferential surface of the cylinder wall part 10, as indicated by the arrow b in FIG. 6, the metering cylinder part 18 ) is inserted into the cylinder wall portion 10 of the nozzle inner cap 8 and mounted.

In the measuring container of the present invention described above, the measuring cap 3 is positioned above the mouth portion 9 so that the position of the extension piece 21 is aligned with the position of the recessed portion 11A in the nozzle plug 8. Since it can be mounted from above, it is much easier to mount than a conventional metering cap with a screw portion interposed therebetween. Further, by rotating the attached measuring cap 3, the lower end 21a of the extension 21 is pushed up by sliding the stepped wall 11B of the mouthpiece 9, so that the measuring cap 3 can be easily removed. can be separated In addition, while the conventional measuring cap with a threaded portion needs to be rotated several times when removing it, in the case of the measuring container 1, the measuring cap 3 can be easily rotated only by rotating the measuring cap 3 around the axis by a fraction of a turn. can be separated

In addition, in the measuring container of the present invention, since the relative upward movement of the measuring cap with respect to the neck portion is restricted by the action of the first engaging portion formed on the inner surface of the engaging wall portion of the measuring cap and the outer circumferential surface of the mouth portion, the contents accommodated in the container body Leakage can be suppressed sufficiently.

In addition, in the measuring container of the present invention, since the vertical length of the engagement wall formed between the extension pieces is shorter than the vertical length of the extension pieces, the visibility of the weighing container is also excellent.

In addition, the measuring container of the present invention is not limited to the measuring container 1 described above. For example, a second engaging portion for restricting the relative upward movement of the measuring cap with respect to the mouth portion may be formed on the outer circumferential surface of the mouth portion and the inner surface of the extension piece. In this way, it is possible to further suppress the unexpected upward detachment of the measuring cap attached to the mouth portion. In addition, in the measuring container of the present invention, a guide projection extending along the stepped wall portion is formed on the outer circumferential surface of the mouth portion above the stepped wall portion, and the measuring cap is attached to the mouth portion on the inner surface of the extension piece as described above. It may also be a measuring container in which a guide protrusion is formed in contact with the upper or lower surface of the guide projection and slides on the upper or lower surface of the guide projection when the metering cap is rotated while being attached to the mouthpiece.

For example, the measuring container 1A of FIG. 7A, FIG. 7B, and FIGS. 8-9 may be sufficient as the measuring container of this invention. 2A, 2B, 3A, and 4A in FIGS. 7A, 7B, and 8 to 9 are denoted with the same reference numerals, and explanation thereof is omitted.

The measuring container 1A is a measuring container except that the nozzle cap 8 is provided with a nozzle cap 9A and the cap 3 is replaced with a cap 3A. Same as (1). The nozzle plug 8A is formed with the nozzle plug 8 except that the third engagement convex portion 28 and the guide convex jaw portion 29 are formed in the concave portion 11A of the outer peripheral surface of the outer cylinder wall 11. same.

The third engagement convex portion 28 is a substantially central portion in the width direction of the recess 11A and extends in the rotation direction (circumferential direction) of the measuring cap 3A formed near the upper end of the outer cylinder wall 11. made up of joe The third engagement convex portion 28 is formed around the axis of the outer cylinder wall 11 within a range of 15 to 20 degrees centered on the central axis C1 in plan view.

In the third engagement convex portion 28 of this example, when viewed from the front, the length from the position corresponding to the bottom of the stepped wall portion 11B in the circumferential direction to the left end is longer than the length from the position to the right end. . In this case, when the mounted measuring cap 3A is rotated counterclockwise around the axis in plan view, the engagement between the third engagement convex portion 28 and the fourth engagement convex portion 30 described later is released. It is easy, and when rotated clockwise, the engagement between the third engagement convex portion 28 and the fourth engagement convex portion 30 described later becomes difficult to release. This makes it possible to regulate the direction of rotation of the measuring cap 3A when removing the measuring cap 3A.

Further, when viewed from the front, the third engagement convex portion 28 has a length from the position corresponding to the bottom of the stepped wall 11B in the circumferential direction to the left end and a length from the position to the right end equal, Ease of rotation in both directions around the axis may be made the same.

The guide projection 29 is lower than the third engagement projection 28 in the recess 11A and extends along the stepped wall 11B to a portion above the stepped wall 11B. . The guide projection 29 extends in the vertical direction and is inclined in the rotation direction (circumferential direction) of the measuring cap 3A. More specifically, the guide convex jaw portion 29 includes a first guide portion 29a composed of a convex jaw extending substantially in the rotation direction of the metering cap 3A, and obliquely upward from the right end of the first guide portion 29a. It is provided with the 2nd guide part 29b which extends obliquely, and it has become a substantially circular arc shape convex downward as a whole.

The guide convex jaw portion 29 is separated from the stepped wall portion 11B and has a front-view shape similar to the front-view shape of the stepped wall portion 11B. The distance between the guide convex jaw portion 29 and the stepped wall portion 11B can be, for example, 2 to 5 mm.

The guide convex jaw portion 29 has a circumferential length (length in the circumferential direction) of 15° to 20° around the axis of the outer cylinder wall 11 around the central axis C1 in plan view. It is formed to converge within the range.

The axial length (circumferential length) of the first guide portion 29a in the guide convex portion 29 is substantially equal to the axial length (circumferential length) of the third engagement convex portion 28. is supposed to Further, a portion extending linearly in the vertical direction in the second guide portion 29b of the guide convex jaw portion 29 relative to the rotation direction (circumferential direction) of the measuring cap 3A and also inclined in the rotation direction. The inclination angle of is, for example, 40 to 70°.

The measuring cap 3A has a fourth engaging convex portion 30 that engages the third engaging convex portion 28 of the outer cylinder wall 11 when the measuring cap 3A is mounted on the inner surface of the extension piece 21 and , It is the same as the measuring cap 3 except that the guide protrusion 31 contacting the lower surface of the guide projection 29 of the outer cylinder wall 11 is formed.

The fourth engagement convex portion 30 is the lower side of the third engagement convex portion 28 of the outer cylinder wall 11 when the metering cap 3A is attached to the neck portion 9A on the inner surface of the extension piece 21. It is formed at a position engaged with. The second engagement portion 32 is formed by the third engagement convex portion 28 and the fourth engagement convex portion 30 . When the measuring cap 3A is attached, the third engagement convex portion 28 and the fourth engagement convex portion 30 of the second engagement portion 32 are engaged, thereby providing a balance of the measurement cap 3A to the caliber portion 9A. The relative upward movement is more regulated. Thereby, it is possible to further suppress the attached measuring cap 3A from unexpectedly falling upward.

The guide projection 31 is below the fourth engagement projection 30 on the inner surface of the extension piece 21, and the guide projection 29 of the guide projection 29 when the measuring cap 3A is attached to the mouthpiece 9A. It is formed at a position in contact with the lower surface.

In the measuring container 1A, it is preferable that elasticity is provided to the extension piece 21. This makes it possible to easily engage the third engagement convex portion 28 and the fourth engagement convex portion 30 of the second engagement portion 32 when attaching the measuring cap 3A.

In the measuring container 1A, in the state where the measuring cap 3A is attached to the neck portion 9A, the first engagement convex portion 25 and the second engagement convex portion 26 of the first engagement portion 27 In addition to the engagement of , the third engagement convex portion 28 and the fourth engagement convex portion 30 of the second engagement portion 32 are engaged. Further, the guide protrusion 31 is locked on the lower surface of the guide convex jaw 29 . In this way, since the upward movement of the measuring cap 3A relative to the mouth portion 9A is more restricted in the measuring container 1A compared to the measuring container 1, the measuring cap 3A is prevented from falling out more strongly.

When the metering cap 3A attached to the mouthpiece 9A is rotated counterclockwise around its axis in plan view, the second engagement convex portion 26 rotates the lower surface of the first engagement convex portion 25. In addition to sliding, the fourth engagement convex portion 30 slides on the lower surface of the third engagement convex portion 28, and the guide protrusion 31 slides on the lower surface of the guide convex jaw portion 29. This guides the metering cap 3A to rotate around the axis stably while suppressing the upward movement of the metering cap 3A with respect to the neck portion 9A. Then, the lower end portion 21a of the extension piece 21 abuts against the stepped wall portion 11B. Further, when the measuring cap 3A is rotated, the engagement of the first engagement convex portion 25 and the second engagement convex portion 26 and the engagement of the third engagement convex portion 28 and the fourth engagement convex portion 30 are When released, as shown in Fig. 10, the lower end portion 21a of the extension piece 21 slides on the stepped wall portion 11B, and thus a force for moving the extension piece 21 obliquely upward is applied. At the same time, since the guide protrusion 31 slides on the lower surface of the guide convex jaw 29, the lower end 21a of the extension 21 stably slides the stepped wall 11B, and the measuring cap 3A is slanted. The upward moving force acts stably. As a result of these, since the measuring cap 3A moves obliquely upward while rotating, the measuring cap 3A can be easily removed.

Measurement of the content in the measuring container 1A can be performed in the same way as in the case of the measuring container 1. Further, subsequent mounting of the measuring cap 3A to the mouth portion 9A can also be performed in the same manner as in the case of the measuring container 1.

Further, the measuring container of the present invention may be a measuring container having a mouthpiece portion having a nozzle inner cap 8B illustrated in FIG. 11 . The nozzle cap 8B is the same as the nozzle cap 8A except that the guide convex tip 29A is provided instead of the guide convex tip 29.

The guide projection 29A includes a third guide 29c extending vertically from the left end of the first guide 29a in the guide projection 29 and inclined in the rotation direction of the measuring cap. It is the same as the guide convex jaw part 29 except that it has more.

In the nozzle plug 8B, the length from the position corresponding to the bottom of the stepped wall part 11B in the circumferential direction as viewed from the front in the third engagement convex part 28 to the left end, and from the position The length to the right end may be the same so that the ease of rotation in both directions around the axis line may be the same.

When both the second engaging portion, the guide convex portion, and the guide protrusion are formed, either of the third engaging convex portion of the second engaging portion and the guide convex portion may be positioned upward on the outer circumferential surface of the neck portion. In addition, on the inner surface of the extension piece, the fourth engagement convex portion of the second engagement portion and the guide protrusion may be positioned upward.

In addition, only one of the second engagement portion, the guide convex jaw portion, and the guide protrusion may be formed.

In the measuring container of the present invention, the first engagement portion may have a fitting structure of the engagement concave portion and the engagement convex portion instead of the first engagement convex portion and the second engagement convex portion. Similarly, when forming the 2nd engagement part, it is good also as a fitting structure by the engagement concave part and the engagement convex part instead of the 3rd engagement convex part and the 4th engagement convex part.

Further, in the measuring container of the present invention, the guide protrusion may contact the upper surface of the guide protrusion when the measuring cap is attached to the mouth part, and the guide protrusion may slide on the upper surface of the guide convex jaw when the measuring cap is rotated. . As a result, when the cap is rotated, the cap can be more easily pushed up, so that the cap can be removed more easily.

Further, in the measuring container of the present invention, the extension piece and the engaging wall portion may be formed so as to be separated from each other. For example, the measuring container of the present invention may be a measuring container having a nozzle cap 8C and a measuring cap 3B as illustrated in FIG. 12 .

Instead of the recessed portion 11C, the nozzle inner cap 8C is formed in a central portion between the two recessed portions 11A around the axis of the outer cylinder wall 11, and is a substantially rectangular shaped patch when viewed from the front. It is the same as the nozzle cap 8 except that the rim 11D is formed. A first engagement convex portion 25 is formed in the recessed portion 11D.

Instead of the engagement wall portion 22, the measuring cap 3B is lowered so as to be separated from the extension piece 21 around the axis from a portion other than the portion where the extension piece 21 is formed in the outer edge portion of the flange portion 20. It is the same as the measuring cap 3 except that it is provided with an engagement wall portion 22A, which is substantially rectangular in shape when viewed from the front, and which hangs down. The 2nd engagement convex part 26 which engages with the 1st engagement convex part 25 is formed in the inner surface in 22 A of engagement wall parts.

In the measuring container, the stepped portions 11b on both sides of the axial line in the recess 11D incline outward around the axial line so that the length of the axial circumferential length of the recess 11D increases as it goes upward. Further, the edges on both sides around the axis in the engagement wall portion 22A incline outward around the axis so that the length around the axis becomes longer as it goes upward, similarly to the stepped portion 11b of the recess 11D. . Since the recessed portion 11D and the engaging wall portion 22A have such a shape, it is easy to rotate the measuring cap 3B around the axis.

Further, in the measuring container of the present invention, the number of extension pieces is not limited to two. Similarly, the number of engagement wall portions is not limited to two. In the measuring container of the present invention, as in the example described above, two extension pieces are formed spaced apart from each other so as to be in a symmetrical position with respect to the axis of the mouth portion when the measurement cap is attached to the mouth portion, and the engaging wall portion rotates the measurement cap. A form in which two are formed spaced apart from each other so as to be symmetrical with respect to the axis of the neck portion is formed in the center between the two extension pieces in the direction.
