(First Embodiment) (FIGS. 1 to 9)
As shown in FIG. 1, the cap 10 to which the present invention is applied is screwed to the side of the mouth portion 2 of the container 1 and is attached to and detached from the mouth portion 2 of the container 1 using the cap attachment portion structure of the present invention. .. The container 1 contains contents such as detergents, disinfectants, chemicals, cosmetics and other liquids, powders and granules. The cap 10 may be directly screwed to the mouth portion 2 of the container 1, but may also be screwed to the mouth portion 2 of the container 1 via the dispenser 3 as in the present embodiment shown in FIG.

In the present embodiment, the mouth portion 2, the dispenser 3, and the cap 10 of the container 1 are assembled by arranging their central axes on the common axis O. Hereinafter, with the container 1 upright, the direction along the common axis O is the vertical direction, the side of the cap 10 is the upper side, and the side of the container 1 is the lower side along the common axis O. Further, the direction along the common axis O is referred to as an axial direction.

When attaching the cap 10 to the mouth 2 of the container 1, it is not always necessary to provide the pouring tool 3, but from the viewpoint of facilitating the pouring of the contents from the container 1 to the cap 10, the mouth of the container 1 is provided. It is preferable to provide the dispenser 3 in 2.

The dispensing tool 3 is made of a synthetic resin molded body such as polypropylene, and is attached to the mouth 2 of the container 1 by driving or screwing, so that the contents of the container 1 can be dispensed. The dispensing tool 3 has a gap and an opening that communicate with the mouth 2 so that the contents can be poured from the mouth 2. In the present embodiment, the dispenser 3 has a large-diameter tubular portion 3A attached to the mouth portion 2 and a small-diameter tubular portion 3B having an outer peripheral screw portion 3C described later, and the large-diameter tubular portion 3A and the small-diameter tubular portion 3B. The boundary portion is a stepped flat surface portion 3P. The dispenser 3 may have a beak-shaped dispenser or the like. The dispenser 3 may have a nozzle (beak-shaped dispenser) that protrudes to the inside of the inner cylinder 30 that is axially higher than the outer cylinder 20 of the cap 10.

The cap 10 is made of a synthetic resin molded product such as polypropylene, is attached to a dispenser 3 provided at the mouth 2 of the container 1, closes the dispenser 3, and dispenses the contents of the container 1 from the dispenser 3. To stop. Alternatively, the cap 10 is removed from the dispenser 3 to open the dispenser 3 so that the contents of the container 1 can be dispensed from the dispenser 3, or the refill contents are injected from the dispenser 3 into the container 1. to enable.

The cap 10 can also serve as a receiving container for the contents dispensed from the dispenser 3 and perform a weighing function (measuring cap). At this time, the cap 10 is preferably made of a transparent body or a translucent body so that the level of the liquid level and the like of the received contents can be visually recognized from the outside world.

The cap 10 has an outer cylinder portion 20 having an inner peripheral screw portion 21 screwed to the outer peripheral screw portion 3C of the dispenser 3 provided at the mouth portion 2 of the container 1, and a tubular wall inside the outer cylinder portion 20. It has a bottomed tubular inner cylinder portion 30 having a 31 and a bottom wall 32. The cap 10 functions as a weighing space for the contents inside the inner cylinder portion 30. The inner cylinder portion 30 projects upward and downward in the axial direction from the outer cylinder portion 20. The end portion of the outer cylinder portion 20 near the bottom wall 32 along the axial direction and the intermediate portion of the inner cylinder portion 30 along the axial direction of the tubular wall 31 are connected by an annular wall 33. The central axes of the outer cylinder portion 20 and the inner cylinder portion 30 are coaxially arranged, and the inner cylinder portion 30 has an opening 31A at one end of the tubular wall 31 in the axial direction. A bottom wall 32 is provided at the other end in the axial direction, and the other end is closed. The bottom wall 32 is the top surface of the cap 10 when the cap 10 is screwed onto the dispenser 3 provided at the mouth 2 of the container 1. For reasons such as design, the annular wall 33 is not limited to the end portion near the bottom wall 32 along the axial direction, but is coupled to the intermediate portion along the axial direction. Is also good.

In the cap 10, the tubular wall 31 in the inner tubular portion 30 is formed into a substantially cylindrical cylindrical portion 34, and two planes 35A and 35B intersect in a V shape with a part of the tubular wall 31 in the circumferential direction. The V-shaped bent portion 35 is formed, and the V-shaped bent portion 35 is continuously formed from one end side to the other end side of the tubular wall 31 in the axial direction of the inner cylinder portion 30. After the contents are injected into the inner cylinder portion 30 and weighed, the V-shaped bent portion 35 formed on the opening 31A side of the outer cylinder portion 20 of the inner cylinder portion 30 is the injection portion of the contents. It becomes 36.

The cap 10 has a V-shaped bent portion 35 and a cylindrical portion 34 continuous in the circumferential direction on the outer peripheral portion including the V-shaped bent portion 35 on the bottom wall 32 side of the annular wall 33 of the inner cylinder portion 30. The deformed outer peripheral portion 37 with which the special jig 100 described later can be engaged is used.

In the cap 10, the outer cylinder portion 20 is in a state where the bottom wall 32 of the inner cylinder portion 30 is arranged on the upper side with respect to the outer peripheral screw portion 3C of the dispenser 3 provided at the mouth portion 2 of the upright container 1. The inner peripheral screw portion 21 provided can be screwed.

However, the cap attachment portion structure of the present invention for attaching and detaching the cap 10 to the dispenser 3 provided at the mouth portion 2 of the container 1 is configured as follows by using the annular body 40 and the special jig 100. Further, the annular body 40 and the special jig 100 constitute a cap removal suppressor that suppresses the removal of the cap 10 that is screwed to the side of the mouth portion 2 of the container 1.

As shown in FIG. 2, the annular body 40 has a cylindrical shape that covers the outer circumference of the cap 10 screwed to the dispenser 3 provided at the mouth portion 2 of the container 1, and is rotatably provided around the cap 10. .. At this time, an annular space S is formed between the annular body 40 and the cap 10.

Specifically, the annular body 40 is made of a synthetic resin molded body such as polypropylene, and as shown in FIG. 3, the cylindrical portion 41 having the upper end fully open (or partially open) and the lower end of the cylindrical portion 41. Includes a flange-shaped engagement portion 42 that projects toward the inner diameter side. In the present embodiment, the flange-shaped engaging portion 42 projects over the entire circumference at the lower end of the cylindrical portion 41.

Here, the cap 10 has an outer cylinder as shown in FIG. 1 when the inner peripheral screw portion 21 of the outer cylinder portion 20 is screwed to the outer peripheral screw portion 3C of the dispenser 3 provided at the mouth portion 2 of the container 1. The lower end of the portion 20 forms a constant gap G with the stepped flat surface portion 3P of the dispenser 3. That is, in the present embodiment, the gap G corresponds to a "gap" formed by the lower end of the cap 10 in the present invention with the container 1. As a result, as shown in FIG. 2, the lower end of the outer cylinder portion 20 of the cap 10 screwed to the side of the mouth portion 2 of the container 1 as described above is the stepped flat surface portion 3P of the dispenser 3. The flange-shaped engaging portion 42 is rotatably engaged and assembled in the above-mentioned gap G formed between the two. The thickness of the flange-shaped engaging portion 42 is formed to be smaller than the length of the gap G.

Therefore, the above-mentioned assembly of the dispenser 3, the cap 10, and the annular body 40, which is performed at the manufacturing stage of the container 1, is performed by the following procedure as shown in FIG. If the dispenser 3 is not provided, the cap 10 and the annular body 40 are directly assembled to the mouth 2 of the container 1.

(1) A flange-shaped engaging portion 42 provided at the lower end of the cylindrical portion 41 of the annular body 40 loaded around the small-diameter tubular portion 3B of the dispenser 3 is seated on the stepped flat surface portion 3P of the dispenser 3.

(2) With the end of the inner cylinder portion 30 of the cap 10 near the bottom wall 32 held by a special tool (a special jig 100 is also possible), the cap 10 is held on the side of the dispenser 3 inside the annular body 40. The inner peripheral screw portion 21 provided in the outer cylinder portion 20 of the cap 10 is screwed to the outer peripheral screw portion 3C provided in the small diameter cylinder portion 3B of the dispenser 3. If the cap 10 is only inserted into the annular body 40, it may be inserted directly without using a special tool.

(3) The dimensional relationship between the cap 10 and the dispenser 3 is such that the outer cylinder portion 20 of the cap 10 is screwed to the outer peripheral screw portion 3C of the dispenser 3 to the fastening end, and the lower end of the outer cylinder portion 20 is in the assembled state. It is set to form a constant gap G (a gap having a size that does not sandwich the flange-shaped engaging portion 42 of the annular body 40) with the stepped flat surface portion 3P of the dispensing tool 3. As a result, the flange-shaped engaging portion 42 of the annular body 40 is rotatably engaged in the above-mentioned gap G.

In the assembled state of the dispenser 3, the cap 10, and the annular body 40 of (3) above, the cylindrical portion 41 of the annular body 40 is at a position higher than the upper end of the cap 10 screwed to the dispenser 3 (height in FIG. 2). The height H of the cylindrical portion 41 is set so as to extend to (ΔH). This is to make it difficult to rotate the cap 10 by pinching it with fingers, and it is preferable that the height H of the cylindrical portion 41 is higher than the upper end of the cap 10 on the entire circumference thereof. It may be higher than the upper end. Further, when there is almost no gap between the cap 10 and the annular body 40 for the fingers to enter (cap 10 in FIG. 11), it is difficult to pinch the cap 10 with the fingers, so the upper end of the cap 10 is slightly higher. , Or the above-mentioned ΔH = 0.

As shown in FIGS. 5 to 7, the special jig 100 is inserted into the annular space S between the annular body 40 and the cap 10, and engages with the outer circumference of the cap 10 in the circumferential direction thereof. In the present embodiment, the dedicated jig 100 is inserted into the annular space S between the annular body 40 and the deformed outer peripheral portion 37 of the inner cylinder portion 30 of the cap 10, and engages with the deformed outer peripheral portion 37 in the circumferential direction. The cap 10 can be screwed. That is, by grasping the special jig 100 and rotating it, the inner peripheral screw portion 21 provided in the outer cylinder portion 20 of the cap 10 can be screwed to the outer peripheral screw portion 3C of the dispenser 3, and the cap 10 can be screwed to the dispenser 3. On the other hand, it can be attached and detached.

Specifically, as shown in FIG. 8, the dedicated jig 100 is provided with an annular grip portion 101 forming a substantially annular shape at the upper end, and extends downward from the lower end surface near the outer circumference of the annular grip portion 101. A cylindrical tubular skirt portion 102 is provided, and a substantially cylindrical tubular engaging portion 103 extending downward from the lower end surface near the inner circumference of the annular grip portion 101 is provided. The outer peripheral diameter of the annular grip portion 101 is larger than the outer peripheral diameter of the annular body 40, the outer peripheral diameter of the tubular skirt portion 102 is slightly smaller than the inner peripheral diameter of the annular body 40, and the inner peripheral diameter of the tubular engaging portion 103 is the cap. It is set to such an extent that it can be in frictional contact with the deformed outer peripheral portion 37 of 10. The vertical length L1 of the tubular skirt portion 102 from the annular grip portion 101 and the vertical length L2 of the tubular engaging portion 103 from the annular grip portion 101 are L1> L.

The annular grip portion 101 of the special jig 100 has a flat upper surface and an outer circumference with a rounded chamfer, and the user's fingers grip a plurality of outer circumferences to grip the tubular skirt portion 102. And the tubular engaging portion 103 are inserted into the above-mentioned annular space S between the annular body 40 and the cap 10. An uneven surface or a knurled finger hook may be formed on the outer circumference of the annular grip portion 101. In the process of inserting the special jig 100 into the annular space S using the annular grip portion 101, the tubular skirt portion 102 is first loosely inserted into the inner circumference of the annular body 40 all around. Then, the dedicated jig 100 is coaxially arranged with the annular body 40 and the cap 10, and subsequently, the circumferential position of the V-shaped bent portion 104B in the deformed inner peripheral portion 104 provided by the tubular engaging portion 103 as described later is capped. A state is set at a rotation angle position that can match the V-shaped bent portion 35 in the deformed outer peripheral portion 37 of 10, and the deformed inner peripheral portion 104 of the tubular engaging portion 103 is pushed into the deformed outer peripheral portion 37 of the cap 10. It engages with the deformed outer peripheral portion 37 in the circumferential direction. At the insertion stroke end of the tubular skirt portion 102 and the tubular engaging portion 103 using the annular grip portion 101, the lower end surface of the annular grip portion 101 near the outer circumference hits the upper end surface of the cylindrical portion 41 of the annular body 40. It can be regulated by contacting or by contacting the lower end surface of the tubular skirt portion 102 with the annular wall 33 of the cap 10.

The tubular skirt portion 102 of the special jig 100 is the above-mentioned insertion stroke end set at a rotation angle position where the deformed inner peripheral portion 104 of the tubular engaging portion 103 engages with the deformed outer peripheral portion 37 of the cap 10. A notch 102A for making the weighing scale M (see FIG. 9) displayed on the irregular outer peripheral portion 37 of the cap 10 visible as described later is provided at an appropriate position in the circumferential direction on the lower end side.

When the tubular engaging portion 103 of the dedicated jig 100 is pushed into the deformed outer peripheral portion 37 of the cap 10 and engages with the deformed outer peripheral portion 37 in the circumferential direction, the tubular engaging portion 103 surrounds the entire circumference of the deformed outer peripheral portion 37. The deformed outer peripheral portion 37 includes a deformed inner peripheral portion 104 having a contour substantially the same as the contour formed by the cylindrical portion 34 and the V-shaped bent portion 35 in the circumferential direction so as to be engaged with each other. At this time, when the tubular engaging portion 103 of the dedicated jig 100 surrounds the deformed outer peripheral portion 37 of the cap 10 on the entire circumference, it is not necessary to make contact with the deformed outer peripheral portion 37 of the cap 10 without a gap on the entire circumference. That is, the deformed inner peripheral portion 104 of the tubular engaging portion 103 can abut and engage with the cylindrical portion 34 and the V-shaped bent portion 35 of the deformed outer peripheral portion 37 of the cap 10, and is substantially cylindrical. A cylindrical portion 104A and a V-shaped bent portion 104B are continuously provided in the circumferential direction.

The dedicated jig 100 has a V-shaped engagement at the circumferential position of the annular grip portion 101 corresponding to the same angle position as the installation position of the V-shaped bent portion 104B in the deformed inner peripheral portion 104 in the top view of the annular grip portion 101. A jig position display unit 104K is provided. The V-shaped engaging position display portion 104K is formed by a V-shaped hole portion 101A formed in the upper surface of the annular grip portion 101. The V-shaped engaging position display portion 104K sets the circumferential position of the V-shaped bent portion 104B in the deformed inner peripheral portion 104 provided in the tubular engaging portion 103 to the V-shaped bent portion 35 in the deformed outer peripheral portion 37 of the cap 10. It is easy to visually understand that the rotation angle position that can be matched is set.

The tubular engaging portion 103 of the dedicated jig 100 has a deformed inner peripheral portion 104 and at the same time has a friction engaging portion 105. In the tubular engaging portion 103 of the present embodiment, the portion of the deformed inner peripheral portion 104 that frictionally engages with the deformed outer peripheral portion 37 of the cap 10 is partially referred to as the friction engaging portion 105. That is, the tubular engaging portion 103 starts at the base of the annular grip portion 101 with the lower end surface or near the base at a plurality of positions in the circumferential direction, and ends at the hanging end of the vertical length L2. A slit 106 is provided over a certain range, and a tongue piece portion 105A sandwiched between the slits 106 adjacent to each other is provided. The inner peripheral diameter of the friction engaging portion 105 formed by each tongue piece portion 105A vertically suspended on the lower end surface of the annular grip portion 101 together with the other tongue piece portions 105A adjacent to the tongue piece portion 105A is the cap 10 in a free state. The diameter is smaller than the outer diameter of the deformed outer peripheral portion 37, and the tongue piece portions 105A are separated from each other by the slit 106 and can be elastically deformed in the radial direction of the tubular engaging portion 103. Therefore, when the tubular engaging portion 103 of the dedicated jig 100 is pushed into the deformed outer peripheral portion 37 of the cap 10, each tongue piece portion 105A of each tongue piece-shaped friction engaging portion 105 becomes the deformed outer peripheral portion 37 of the cap 10. It comes into contact with the jig and engages in friction.

It should be noted that the inner peripheral surface of each tongue piece portion 105A forming the friction engaging portion 105 of the tubular engaging portion 103 extends along the vertical direction of the tubular engaging portion 103. A protruding rib 107 that protrudes inward of the tubular engaging portion 103 and press-contacts the deformed outer peripheral portion 37 of the cap 10 is provided. The protruding rib 107 increases the frictional engagement force of the frictional engagement portion 105 in contact with the deformed outer peripheral portion 37 of the cap 10.

Further, a support rib 108 made of a plate piece or the like is joined to a part of the back surface of each tongue piece portion 105A in the tubular engaging part 103 along the vertical direction of the tubular engaging part 103. Each support rib 108 is joined to the annular grip portion 101 and the tubular skirt portion 102 to support each tongue piece portion 105A in the radial direction.

Therefore, the tubular engaging portion 103 of the dedicated jig 100 engages both the deformed inner peripheral portion 104 and the friction engaging portion 105 with the deformed outer peripheral portion 37 of the cap 10 in the outer peripheral portion of the cap 10 and its circumferential direction. It will surely engage.

The dedicated jig 100 includes a key-shaped engaging portion 109 at a plurality of positions in the circumferential direction of the inner peripheral surface of the tubular skirt portion 102 (two positions facing each other in the diameter direction in the present embodiment). The key-shaped engaging portion 109 will be described in detail in the second embodiment.

The procedure for attaching and detaching the cap 10 using the special jig 100 is as follows.
(A) Procedure for removing the cap 10 using the dedicated jig 100
(1) The outer circumference of the annular grip portion 101 provided in the dedicated jig 100 is gripped, and the tubular skirt portion 102 and the tubular engaging portion 103 are inserted into the annular space S between the cap 10 and the annular body 40. At this time, the tubular skirt portion 102 has a special jig 100 coaxial with the annular body 40 and the cap 10 following the inner peripheral surface of the annular body 42, and is V-shaped provided on the upper surface of the annular grip portion 101. Using the engagement position display portion 104K (V-shaped hole portion 101A) as a guide, the circumferential position of the V-shaped bent portion 104B of the deformed inner peripheral portion 104 corresponding to the V-shaped engagement position display portion 104K is a variant of the cap 10. A rotation angle position that can match the V-shaped bent portion 35 on the outer peripheral portion 37 is set, and the tubular skirt portion 102 and the tubular engaging portion 103 are inserted into the annular space S as described above.

In the above-mentioned insertion process by the annular grip portion 101, the deformed inner peripheral portion 104 of the tubular engaging portion 103 is pushed into the deformed outer peripheral portion 37 of the cap 10 and engaged with the deformed outer peripheral portion 37 in the circumferential direction. do. At this time, the friction engaging portion 105 of the tubular engaging portion 103 is also pushed into the deformed outer peripheral portion 37 of the cap 10 to be fitted, and is elastically contacted with the deformed outer peripheral portion 37 to be frictionally engaged.

(2) By grasping the annular grip portion 101 and rotating the annular grip portion 101 in the removal direction of the cap 10, the rotational force of the annular grip portion 101 is rubbed against the deformed inner peripheral portion 104 of the tubular engaging portion 103. It is transmitted to the cap 10 via the engaging portion 105, and the cap 10 is screwed together with the special jig 100 in the removal direction to screw the dispenser 3 provided at the mouth portion 2 of the container 1 to the outer peripheral screw portion 3C. It is unraveled and removed from the dispenser 3.

After the screwing between the cap 10 and the dispenser 3 due to the rotation of the annular grip portion 101 is released, the tubular skirt portion 102 and the tubular engaging portion 103 are connected to the above-mentioned annular space S by using the annular grip portion 101. When pulled out from, the cap 10 held by the tubular engaging portion 103 by being elastically in contact with the friction engaging portion 105 of the tubular engaging portion 103 is held together with the dedicated jig 100 in the annular space S. Is pulled out from. This completes the removal of the cap 10.

(3) The cap 10 and the special jig 100 pulled out from the annular space S are turned upside down, and as shown in FIG. 9, the annular grip portion 101 is held by fingers or placed on a table with the flat upper surface facing down. Under the condition, the contents of the container 1 from which the annular body 40 is removed are poured out from the dispenser 3 into the inner cylinder portion 30 of the cap 10 and weighed. At this time, the measurement scale M displayed on the deformed outer peripheral portion 37 of the inner cylinder portion 30 of the cap 10 can be visually recognized from the cutout portion 102A of the tubular skirt portion 102.

The cap 10 that has been unscrewed with the dispenser 3 is removed from the dispenser 3 in a state where the cap 10 is separated from the special jig 100 by being unheld by the tubular engaging portion 103 of the special jig 100. May be done. Further, when the contents of the container 1 are poured into the inner cylinder portion 30 of the cap 10 and weighed, the cap 10 may be in a state of being separated from the dedicated jig 100. Further, the cap 10 may not be used for measuring the contents of the container 1, but may be poured directly from the container 1 to the destination.

(B) Installation procedure of the cap 10 using the dedicated jig 100
(1) When the cap 10 once removed from the dispenser 3 provided at the mouth 2 of the container 1 is reattached to the dispenser 3, one finger grips the outer circumference of the annular grip portion 101 of the special jig 100.
