Description

Weighing container

The present invention relates to a weighing container.
This application claims priority based on Japanese Patent Application No. 2014-241177 filed in Japan on November 28, 2014, the contents of which are incorporated herein by reference.

For example, as a cap attached to a container body that stores liquid contents such as a softener and a liquid detergent, an engagement wall portion is generally provided with a measuring function so that the measured contents can be seen from the outside. Transparent measuring caps are widely used. In such a measuring cap, a measuring line or the like is formed as a relief by printing or molding on a measuring tube portion positioned inside the engaging wall portion.

As a mode of attaching the measuring cap to the mouth and neck of the container body, a mode in which the measuring cap is screwed to the mouth and neck in order to prevent the liquid contents from leaking during transportation or handling is common. is there. However, in the case of a container with a measuring cap screwed on, if the fingers are wet with water when handling, or if the contents such as cleaning agents adhere to the fingers, the fingers are slippery and it is difficult to open and close the measuring cap. become.

In addition, as an aspect in which the cap is attached to the mouth / neck portion of the container body, an aspect in which the cap is fitted to the mouth / neck portion has also been proposed.
For example, an engagement concave portion is formed at the lower end portion of the outer wall surface of the tapered mouth-neck portion that decreases in diameter toward the upper end, and an engagement convex portion that fits the engagement concave portion at the lower end portion of the inner wall surface of the cap. The formed container is mentioned (for example, patent document 1). In the container, the engagement concave portion and the engagement convex portion are released from each other by pressing inward the vertical center portions of the opposing side walls of the cap fitted and attached to the mouth and neck portion. In this state, the cap is removed from the mouth and neck by lifting the cap upward.
However, the container requires a two-step operation for removing the cap, and it is difficult to remove the cap when the finger is slippery due to adhesion of water or a cleaning agent.

In addition, the lower neck portion has an octagonal mouth and neck portion, and the lower end portion has a quadrangular cap, and the first rib is located on the outer wall surface of the mouth and neck portion above the lower end portion. Examples include a container formed and formed on the inner wall surface of the cap with a second rib that is locked to the lower surface of the first rib when the cap is attached to the mouth and neck (for example, Patent Document 2). . In the container, the first rib and the second rib are respectively arranged at positions corresponding to every other outer surface around the axis line among the eight outer surfaces of the lower end portion of the mouth-and-neck portion. When removing the cap, the cap mounted on the mouth-and-neck portion is rotated by 1/8 turn, the fitting of the first rib and the second rib is released, and the cap is lifted and removed in that state.
However, in the container, since a force is required to rotate the cap having a square bottom shape of the lower end portion relative to the octagonal mouth and neck portion, the finger is caused by adhesion of water or a cleaning agent. When it is slippery, it is difficult to remove the cap.

In addition, an engagement recess is formed on the outer wall surface of the mouth-and-neck portion having a tapered shape with a diameter decreasing toward the upper end and a rectangular planar shape, and the engagement recess is formed on the inner wall surface of the cap having a rectangular planar shape. A container in which an engaging convex part to be fitted is formed (for example, Patent Document 3). In the container, when the cap is removed, the cap mounted on the mouth and neck is rotated to release the engagement between the engagement concave portion and the engagement convex portion, and the cap is lifted and removed in that state.
However, in the container, since a force is required to rotate the cap having a rectangular planar shape with respect to the mouth-and-neck portion having a rectangular planar shape, the cap is easily slipped due to adhesion of water or a cleaning agent. It is difficult to remove.

In addition, in a container of a type that fits and attaches the cap as described above, when a measuring cap having a measuring cylinder portion is adopted as the cap, the visibility of the measuring line from the outside in the radial direction is poor, and the content is not measured. There is a problem that becomes difficult.

An engaging convex portion 25 is formed.
The first engaging convex portion 25 has a length around the axis (circumferential length) in a range of 15 ° to 20 ° around the axis of the outer cylinder wall 11 and centered on the central axis C1 in plan view. It is formed to fit inside.

As shown in FIGS. 4A to 4C, the measuring cap 3 includes a cylindrical measuring tube portion 18, a lid portion 19 that closes one open end of the measuring tube portion 18, and an outer side from the peripheral surface of the measuring tube portion 18. A portion other than the portion where the annular flange portion 20 projecting in plan view, the two extending pieces 21 suspended from the outer edge portion of the flange portion 20, and the extending piece 21 at the outer edge portion of the flange portion 20 are formed. And an engaging wall portion 22 suspended from the wall. Thus, the measuring cap 3 has a cylindrical shape with a lid, and has a flange portion projecting outward at the center in the height direction. A protruding portion that protrudes outward from the outer edge portion of the flange portion 20 may be formed outside the extending piece 21 and the engaging wall portion 22 of the flange portion 20.
Further, a ring portion 23 that protrudes downward is formed on the inner peripheral edge of the flange portion 20.

A part of the lower end side of the measuring tube portion 18 is inserted into the tube wall portion 10 of the nozzle plug 8 so as to surround the dispensing tube 17.
As shown in FIG. 4C, a scale portion 24 having scale lines for measurement and numbers for capacity display is printed, stamped, etc. on the portion between the two extending pieces 21 on the peripheral wall of the measurement cylinder portion 18. Formed by means. Thereby, it is possible to grasp the amount of contents such as liquid injected from the opening 18a of the measuring cylinder portion 18 in a state where the measuring cap 3 is inverted.
When the measuring cap 3 is attached to the nozzle plug 8, the flange portion 20 is put on the opening at the upper end of the cylindrical wall portion 10 of the nozzle plug 8 in the neck 9.

The extending piece 21 is a thin piece with a front-view tongue shape whose width decreases toward the lower end, and the lower end portion 21a has a curved shape when viewed from the front.
Two extending pieces 21 are formed at intervals of 180 ° around the axis of the flange portion 20, that is, so as to be symmetrical with respect to the central axis C 1 when the measuring cap 3 is attached to the mouth-and-neck portion 9. Yes. The two extending pieces 21 are respectively placed along the two recesses 11 A on the outer peripheral surface of the cylindrical wall portion 10 of the nozzle plug 8 when the measuring cap 3 is attached.

The width around the axis of the upper end of the extension piece (the length in the circumferential direction) is preferably within the range of 40 to 70 ° around the axis of the flange, centered on the central axis in plan view. . When the measuring cap is attached to the nozzle plug, the center axis of the flange portion and the center axis of the mouth and neck portion coincide.
When the extension piece and the engaging wall portion are integrally formed without being separated from each other, the width around the axis of the upper end portion of the extension piece is the edge of the extension piece on the outer surface of the extension piece. It means the distance around the axis between the boundary points between the portion and the edge portion of the engaging wall. For example, in this example, the curved edge portion of the upper end portion of the extension piece 21 and the linear shape of the engagement wall portion 22 on both sides in the circumferential direction of the extension piece 21 on the outer surface of the extension piece 21. The distance around the axis between the boundary points with the edge portion is defined as the width around the axis of the upper end portion of the extension piece 21.

The length of the extending piece in the vertical direction is preferably 10 to 25 mm. The length in the vertical direction of the extended piece means the distance from the lower surface of the flange portion to the lower end of the extended piece.

In this example, as shown in FIG. 2A, when the measuring cap 3 is attached and the lower end portion 21a of the extended piece 21 is aligned with the bottom of the stepped wall portion 11B in the front view, the lower end portion of the extended piece 21 21a is slightly separated from the step 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 step wall portion 11B when the measuring cap 3 is attached and rotated.
When the circumferential position of the lower end of the extended piece is aligned with the position of the bottom of the stepped wall when viewed from the front, the lower end of the extended piece and the stepped wall are separated. The distance between the lower end of the protruding piece and the bottom of the stepped wall portion in front view is preferably 0.3 to 1.2 mm.

In the present invention, the lower end of the extended piece may be in contact with the stepped wall when the lower end of the extended piece is aligned with the bottom of the stepped wall in a front view.

In this example, the width of the extending piece 21 is narrower than the width of the recess 11A formed on the outer peripheral surface of the outer cylindrical wall 11 of the nozzle plug 8. Thereby, the side edge part above the lower end part 21a in the extension piece 21 is spaced apart from the level | step difference wall part 11B of both sides at the time of mounting | wearing of the measurement cap 3. As shown in FIG.

The engagement wall portion 22 is a rectangular thin piece having a longer length around the axis than the length in the vertical direction when viewed from the front.
Two engaging wall portions 22 are formed around the axis of the flange portion 20 at intervals of 180 °, that is, symmetrically with respect to the central axis C1 when the measuring cap 3 is attached to the mouth-and-neck portion 9. ing. Each of the two extending pieces 21 is formed from one extending piece 21 to the other extending piece 21. That is, the two extending pieces 21 and the two engaging wall portions 22 are integrated.
When the measuring cap 3 is attached, the engaging wall portion 22 is placed along the two recess portions 11C on the outer peripheral surface of the cylindrical wall portion 10 of the nozzle plug 8.

The lower end of the engagement wall portion 22 is located closer to the flange portion 20 than the lower end of the extension piece 21. That is, the vertical length of the engagement wall portion 22 is shorter than the vertical length of the extension piece 21. Thereby, when measuring the contents in a state where the measuring cap 3 is inverted, the scale portion 24 is easily visually recognized.

The length of the engagement wall portion 22 in the vertical direction is preferably 3 to 10 mm, and more preferably 5 to 7 mm. If the length of the engagement wall portion 22 in the vertical direction is equal to or greater than the lower limit value, it is easy to form a second engagement protrusion 26 described later. If 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 contents becomes better.

On the inner surface of the engagement wall portion 22, a second engagement convex portion 26 that is engaged with the first engagement convex portion 25 of the outer cylindrical wall 11 when the measuring cap 3 is attached is formed.
The second engagement convex portion 26 engages with the lower side of the first engagement convex portion 25 of the outer cylindrical wall 11 when the measuring cap 3 is attached to the mouth and neck portion 9 on the inner surface of the engagement wall portion 22. It is formed as follows. A first engaging portion 27 is formed by the first engaging convex portion 25 and the second engaging convex portion 26. When the measuring cap 3 is attached, the first engaging convex portion 25 and the second engaging convex portion 26 of the first engaging portion 27 are engaged with each other, so that the measuring cap 3 is moved upward relative to the mouth and neck portion 9. Can be regulated. Thereby, it is possible to prevent the attached measuring cap 3 from being unexpectedly pulled out.

In the weighing container 1, it is preferable that the engagement wall portion 22 is provided with elasticity. Thereby, at the time of mounting | wearing with the measurement cap 3, the 1st engagement convex part 25 and the 2nd engagement convex part 26 of the 1st engagement part 27 can be easily engaged.

(Production method)
As a manufacturing method of 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, a method of integrally molding by blow molding using an olefin-based synthetic resin such as polyethylene can be given. As a manufacturing method of the nozzle plug 8 of the container body 2, for example, a method of integrally molding by injection molding using an olefin-based synthetic resin such as polypropylene can be cited. As a manufacturing method of the measuring cap 3, for example, there is a method of integrally molding by injection molding using an olefin-based synthetic resin such as polyethylene.
In addition, the manufacturing method of the container main body 2 and the measurement cap 3 is not limited to an above-described method.

(Function and effect)
Hereinafter, the removal operation, measurement operation, and attachment 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, the nozzle plug 8 is mounted on the protruding cylinder portion 7 with the dispensing cylinder 17 facing upward with the contents stored in the container body 2. The Since the opening of the protruding cylinder 7 is liquid-tightly closed by the seal lip 15 of the nozzle plug 8, the threaded portion of the screw 7 a of the protruding cylinder 7 and the screw 11 a of the nozzle plug 8 is threaded. Liquid leakage through the is prevented.

In a state in which the measuring cap 3 is mounted on the nozzle plug 8 of the mouth / neck portion 9, as shown in FIGS. 1 and 2A, the two extending pieces 21 of the measuring cap 3 are on the outer peripheral surface of the cylindrical wall portion 10. Along the recess 11A. Further, the two engaging wall portions 22 of the measuring cap 3 are arranged along the recessed portion 11 C portion on the outer peripheral surface of the cylindrical wall portion 10. The cylindrical wall portion 10 of the nozzle plug 8 is sandwiched between the extending piece 21 and the engaging wall portion 22.
Further, in this state, the second engagement convex portion 26 formed on the measuring cap 3 is engaged with the lower surface of the first engagement convex portion 25 formed on the outer peripheral surface of the mouth / neck portion 9. Thereby, the relative upward movement of the measuring cap 3 with respect to the mouth-and-neck portion 9 is restricted.

To remove the measuring cap 3, first, the upper part of the measuring cap 3 is picked with a finger, and the measuring cap 3 is slightly rotated counterclockwise (counterclockwise) around the axis in plan view. At this time, the second engaging convex portion 26 slides on the lower surface of the first engaging convex portion 25 in the first engaging portion 27, and the lower end portion 21 a of the extension piece 21 of the measuring cap 3 is the nozzle inner plug 8. It contacts the step wall portion 11B. When the measuring cap 3 is further 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 slides on the step wall portion 11B. By doing so, the force which moves the extension piece 21 diagonally upward acts. As a result, the extension piece 21 rises along the step wall portion 11B as shown by an arrow a in FIG. 5, and as a result, the measuring cap 3 moves obliquely upward while rotating. Can be removed.
In the measuring container 1, even when the measuring cap 3 is rotated clockwise (clockwise) around the axis in plan view, the measuring cap 3 can be easily removed in the same manner.

Thereafter, as shown in FIG. 4C, the measuring cap 3 is inverted, the container body 2 is tilted so that the tip of the dispensing tube 17 of the nozzle plug 8 faces downward, and the contents in the container body 2 are poured into the spout 16b. Then, it is injected into the measuring cylinder portion 18 through the dispensing cylinder 17. The amount of contents injected into the measuring cylinder portion 18 of the measuring cap 3 can be grasped by the scale portion 24.
In the measuring cap 3 when performing the measuring operation, since the vertical length of the engaging wall portion 22 is short, the scale portion 24 is easily visible from between the

extended pieces

21, 21 and is accommodated in the measuring tube portion 18. The amount of contents can be accurately grasped.
After the measurement is completed and the contents are used, the measurement cylinder portion 18 is aligned as shown by the arrow b in FIG. 6 while aligning the position of the extending piece 21 with the recess 11A on the outer peripheral surface of the cylinder wall portion 10. Is inserted into the cylindrical wall portion 10 of the nozzle plug 8 and attached.

In the measuring container of the present invention described above, since the measuring cap 3 can be attached from above the mouth-and-neck portion 9 so that the position of the extending piece 21 matches the position of the recess 11A in the nozzle inner plug 8, the conventional screw It is much easier to install than a measuring cap via the part. Moreover, since the lower end part 21a of the extension piece 21 slides up and rises by the step wall part 11B of the mouth neck part 9 by rotating the attached measurement cap 3, the measurement cap 3 can be removed easily. it can. Further, the conventional measuring cap via the threaded portion needs to be rotated many times when being removed, but in the measuring container 1, it is easy to rotate the measuring cap 3 around the axis by a few turns. Can be removed.

In the measuring container according to the present invention, the measuring cap is moved upward relative to the mouth and neck by the action of the first engaging portion formed on the inner surface of the engaging wall of the measuring cap and the outer peripheral surface of the mouth and neck. Therefore, leakage of contents stored in the container body can be sufficiently suppressed.
Further, in the measuring container of the present invention, the vertical length of the engaging wall portion formed between the extended pieces is shorter than the vertical length of the extended piece. Are better.

The measuring container of the present invention is not limited to the measuring container 1 described above. For example, the 2nd engaging part which controls the relative upward movement of the measurement cap with respect to a mouth neck part may be formed in the outer peripheral surface of a mouth neck part, and the inner surface of an extension piece. Thereby, it can suppress more that the measurement cap with which the mouth neck part was mounted | worn unexpectedly pulls upwards. In the measuring container of the present invention, a guide ridge extending along the step wall portion is formed on the upper portion of the outer peripheral surface of the mouth-neck portion, and the measuring cap is formed on the inner surface of the extension piece. Is in contact with the upper surface or lower surface of the guide ridge when mounted on the mouth and neck, and the upper surface or lower surface of the guide ridge when the measuring cap is rotated while mounted on the mouth and neck. It may be a weighing container in which a sliding guide projection is formed.

For example, the measuring container of the present invention may be the measuring container 1A illustrated in FIGS. 7A, 7B, and 8 to 9. 7A, 7B, and FIGS. 8 to 9 that are the same as those in FIGS. 2A, 2B, 3A, and 4A are assigned the same reference numerals, and descriptions thereof are omitted.
The measuring container 1 A is the same as the measuring container 1 except that the measuring container 1 A includes a mouth / neck portion 9 A having a nozzle plug 8 A instead of the nozzle plug 8 and a measuring cap 3 A instead of the measuring cap 3. The nozzle plug 8A is the same as the nozzle plug 8 except that the third engaging protrusion 28 and the guide protrusion 29 are formed in the recess 11A on the outer peripheral surface of the outer cylinder wall 11.

The third engaging convex portion 28 is a convex portion extending in the rotational direction (circumferential direction) of the measuring cap 3A, which is formed at a substantially central portion in the width direction of the concave portion 11A and near the upper end of the outer cylindrical wall 11. Become. The third engaging convex portion 28 is formed within the range of 15 to 20 ° around the central axis C1 in plan view around the axis of the outer cylindrical wall 11.
In the third engagement convex portion 28 in this example, the length from the position corresponding to the bottom of the stepped wall portion 11B in the circumferential direction to the left end in the front view is longer than the length from the position to the right end. In this case, when the attached measuring cap 3A is rotated counterclockwise around the axis in plan view, the engagement of the third engagement convex portion 28 and the fourth engagement convex portion 30 described later is easily disengaged. When rotated around, the engagement of the third engaging convex portion 28 and the fourth engaging convex portion 30 described later is difficult to be disengaged. Thereby, the rotation direction of the measuring cap 3A when removing the measuring cap 3A can be regulated.
Note that the third engagement convex portion 28 has a length from the position corresponding to the bottom of the stepped wall portion 11B in the circumferential direction to the left end in the circumferential direction and a length from the position to the right end equal to each other around the axis. The ease of turning in both directions may be the same.

The guide protrusions 29 extend along the step wall 11B below the third engagement protrusions 28 in the recess 11A and above the step wall 11B. The guide ridge 29 extends in the vertical direction and is inclined in the rotation direction (circumferential direction) of the measuring cap 3A. More specifically, the guide ridge portion 29 is inclined obliquely upward from the first guide portion 29a made of a ridge extending substantially in the rotation direction of the measuring cap 3A and the right end portion of the first guide portion 29a. The second guide portion 29b extends, and has a substantially arc shape that protrudes downward as a whole.

The guide ridge 29 is separated from the step wall 11B, and the front view shape is similar to the front view shape of the step wall 11B. The distance between the guide ridge 29 and the step wall 11B can be set to 2 to 5 mm, for example.
The guide ridge 29 has a length around its axis (circumferential length) within a range of 15 ° to 20 ° around the axis of the outer cylinder wall 11 and centered on the central axis C1 in plan view. It is formed to fit.
The length around the axis of the first guide portion 29a (the length in the circumferential direction) in the guide ridge 29 is substantially equal to the length around the axis of the third engagement projection 28 (the length in the circumferential direction). It has become. In addition, with respect to the rotation direction (circumferential direction) of the measuring cap 3A, the inclination angle of the portion of the second guide portion 29b of the guide protrusion 29 that extends linearly in the vertical direction and is inclined in the rotation direction is, for example, 40-70 °.

The measuring cap 3 A is provided on the inner surface of the extension piece 21 with a fourth engaging convex portion 30 that engages with the third engaging convex portion 28 of the outer cylindrical wall 11 when the measuring cap 3 A is attached, and the guide of the outer cylindrical wall 11. The measuring cap 3 is the same as the measuring cap 3 except that a guide protrusion 31 that is in contact with the lower surface of the ridge 29 is formed.

The fourth engaging convex portion 30 is a position on the inner surface of the extending piece 21 that engages with the lower side of the third engaging convex portion 28 of the outer cylindrical wall 11 when the measuring cap 3A is attached to the mouth / neck portion 9A. Is formed. A second engaging portion 32 is formed by the third engaging convex portion 28 and the fourth engaging convex portion 30. When the measuring cap 3A is attached, the third engaging convex portion 28 of the second engaging portion 32 and the fourth engaging convex portion 30 engage with each other, so that the measuring cap 3A moves upward relative to the neck 9A. More regulated. Thereby, it can suppress more that the measurement | capacitance cap 3A with which it mounted | worn is pulled out upwards unexpectedly.

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

In the weighing container 1A, it is preferable that the extension piece 21 is given elasticity. Thereby, the 3rd engagement convex part 28 and the 4th engagement convex part 30 of the 2nd engagement part 32 can be easily engaged at the time of mounting | wearing with the measurement cap 3A.

In the measuring container 1A, in a state where the measuring cap 3A is mounted on the mouth / neck portion 9A, in addition to the engagement of the first engaging convex portion 25 and the second engaging convex portion 26 of the first engaging portion 27, The 3rd engagement convex part 28 of the 2 engaging part 32 and the 4th engagement convex part 30 are engaging. Further, the guide protrusion 31 is locked on the lower surface of the guide ridge 29. Thus, in the measuring container 1A, the relative upward movement of the measuring cap 3A with respect to the mouth / neck portion 9A is further restricted as compared with the measuring container 1, so that the measuring cap 3A is more strongly prevented from coming off.

When the measuring cap 3A attached to the mouth / neck portion 9A is rotated counterclockwise around the axis in plan view, the second engaging convex portion 26 slides on the lower surface of the first engaging convex portion 25. At the same time, the fourth engagement protrusion 30 slides on the lower surface of the third engagement protrusion 28, and the guide protrusion 31 slides on the lower surface of the guide protrusion 29. As a result, the measuring cap 3A is guided so as to rotate stably around the axis while suppressing the relative movement of the measuring cap 3A relative to the mouth-and-neck portion 9A. And the lower end part 21a of the extension piece 21 contact | abuts to the level | step difference wall part 11B. When the measuring cap 3A is further 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 released. As shown in FIG. 10, the lower end portion 21 a of the extension piece 21 slides on the step wall portion 11 B, so that a force that moves the extension piece 21 obliquely upward acts. At the same time, since the guide protrusion 31 slides on the lower surface of the guide ridge portion 29, the lower end portion 21a of the extension piece 21 stably slides on the step wall portion 11B and moves the measuring cap 3A obliquely upward. Works stably. As a result, since the measuring cap 3A moves obliquely upward while rotating, the measuring cap 3A can be easily removed.

The weighing of the contents in the weighing container 1A can be performed in the same manner as in the weighing container 1. Further, the mounting of the measuring cap 3A to the mouth / neck portion 9A can 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 provided with a mouth and neck portion having a nozzle plug 8B illustrated in FIG. The nozzle plug 8B is the same as the nozzle plug 8A except that a guide protrusion 29A is provided instead of the guide protrusion 29A.
The guide ridge portion 29A is a guide except that it further includes a third guide portion 29c extending in the vertical direction from the left end portion of the first guide portion 29a in the guide ridge portion 29 and inclined in the rotational direction of the measuring cap. It is the same as the ridge portion 29.
In the nozzle plug 8B, the length from the position corresponding to the bottom of the step wall 11B in the circumferential direction to the left end in the third engagement convex portion 28 is equal to the length from the position to the right end. Thus, the ease of rotation in both directions around the axis may be the same.

In the case of forming both the second engaging portion and the guide ridge portion and the guide protrusion, on the outer peripheral surface of the mouth-and-neck portion, which is the third engagement convex portion and the guide ridge portion of the second engagement portion. It may be located above. In addition, on the inner surface of the extension piece, any of the fourth engagement convex portion and the guide protrusion of the second engagement portion may be positioned above.
Moreover, you may form only any one of a 2nd engaging part, a guide convex part, and a guide protrusion.

In the measuring container of the present invention, the first engagement portion may have a fitting structure including an engagement concave portion and an engagement convex portion instead of the first engagement convex portion and the second engagement convex portion. Similarly, when the second engaging portion is provided, a fitting structure including an engaging concave portion and an engaging convex portion may be used instead of the third engaging convex portion and the fourth engaging convex portion.
In the measuring container of the present invention, the guide projection comes into contact with the upper surface of the guide projection when the measurement cap is attached to the mouth and neck, and the guide projection is guided by the guide projection when the measurement cap is rotated. You may make it slide on the upper surface. Thereby, when the measuring cap is rotated, the measuring cap is more easily lifted, so that the measuring cap can be removed more easily.

Moreover, in the measuring container of this invention, you may form so that an extension piece and an engaging wall part may space apart, respectively. For example, the measuring container of the present invention may be a measuring container including the mouth and neck portion having the nozzle plug 8C and the measuring cap 3B illustrated in FIG.
The nozzle plug 8C has a configuration in which a concave portion 11D having a substantially rectangular shape in front view is formed in the central portion between the two concave portions 11A around the axis of the outer cylinder wall 11 instead of the concave portion 11C. Is the same as the nozzle plug 8. A first engaging protrusion 25 is formed in the recess 11D.

The measuring cap 3B was suspended from the portion other than the portion where the extended piece 21 was formed on the outer edge portion of the flange portion 20 so as to be separated from the extended piece 21 around the axis instead of the engaging wall portion 22. The front view shape is the same as the measuring cap 3 except that the engagement wall portion 22A has a substantially rectangular shape. A second engagement convex portion 26 that engages with the first engagement convex portion 25 is formed on the inner surface of the engagement wall portion 22A.

In the measuring container, the step portions 11b on both sides around the axis of the recess 11D are inclined outwardly around the axis so that the length around the axis of the recess 11D becomes longer toward the upper side. Further, the edges on both sides around the axis of the engaging wall 22A are inclined outwardly about the axis so that the length around the axis becomes longer as it goes upward, like the stepped portion 11b of the recess 11D. is doing. Since the recess 11D and the engagement wall 22A have such a shape, the measuring cap 3B can be easily rotated around the axis.

Further, in the measuring container of the present invention, the number of extending pieces is not limited to two. Similarly, the number of engaging wall portions is not limited to two. In the measuring container of the present invention, as in the example described above, the extending pieces are separated from each other so that they are symmetrical with respect to the axis of the mouth-neck when the measuring cap is attached to the mouth-neck. Two of the two engaging wall portions are spaced apart from each other so as to be symmetrical with respect to the axis of the mouth-neck portion at the center between the two extending pieces in the rotation direction of the measuring cap. The formed aspect is preferable.
