[Modes for carrying out the invention]

[0011] Next, the dispensing cap of the present invention will be described with reference to the drawings showing an embodiment of the dispensing cap, which comprises a cap body having a transition stopper. [Examples]

[0012] In Figure 1, A is the container body, B is the cap body attached to container body A, and C is the lid that is screwed onto cap body B. The mouth portion 1 of the container body A is equipped with a locking projection 2 that fits onto the cap body B to prevent it from coming off and a neck ring 3 that protrudes radially from below the locking projection 2.

[0013] As shown in Figures 1 to 3, the cap body B consists of an outer cylinder 5 on the outer circumference, an inner cylinder 6 on the inner circumference, and an upper wall 7 located on the top surface side of the opening 1. It includes a mounting portion 4 that forms an annular groove into which the opening 1 is fitted, a threaded wall portion 8 erected from the upper wall 7, a dispensing cylinder 10 connected to the upper end of the threaded wall portion 8 via a stepped portion 9, and a locking plate portion D that extends radially from the lower outer circumference of the mounting portion 4 and, when the lid is opened, detaches and locks the sealing portion C2 of the lid C (described later) from the threaded cap C1. A sound-emitting projection 11 is provided on the outer circumference of the stepped portion 9 to indicate the end of screwing the lid C onto the cap body B.

[0014] The dispensing cylinder 10 has a spout for dispensing the contents contained in the container body A, and has a lip portion 12 at its upper part that widens in diameter and curves outward. A transition plug 15 is integrally connected to the inner circumferential surface of the lower end of the dispensing cylinder 10 via a thin-walled weakened portion 14 formed around its entire circumference.

[0015] The transition plug body 15 stands upright upward and consists of a cylindrical tubular wall 16 and an upper wall 17 covering its upper surface. On the outer periphery of the upper part of the tubular wall 16, a first tooth part 18 is recessed in the circumferential direction, and the first tooth part 18 engages with a second tooth part 47 of the lid body C described later. In this embodiment, two first tooth parts 18 are provided, but the number is not limited to two, and a plurality of them can be provided according to the shape of the transition plug body 15 and the like.

[0016] At the lower part of the tubular wall 16, an enlarged-diameter part 22 having a predetermined height from the lower surface is provided on the outer peripheral side. On the outer peripheral surface of the enlarged-diameter part 22, a first engaging protrusion 19 protrudes annularly, and further, a flange part 23 that gradually thins toward the outside and is connected to the thin-wall weakened part 14 is continuously provided. In this embodiment, the cap body B includes a transition plug body 15 continuously provided through a thin-wall weakened part 14 formed on the inner peripheral surface of the pouring cylinder 10. However, the presence or type of the plug removal mechanism can be any. For example, as the plug removal mechanism, a pouring cap that pulls up a removal part from a partition wall by a pull ring to open the plug may be used.

[0017] The threaded wall part 8 is vertically provided from the outer peripheral edge of a stepped part 9 continuously provided at the lower part of the pouring cylinder 10 with an inner peripheral edge. On the outer peripheral surface, a first thread part (male thread) 24 is provided. The first thread part 24 is composed of an inclined upper surface with a steep inclination on the upper surface and a flat lower surface with a flat lower surface, unlike a normal thread profile where the cross-section is not vertically symmetric.

[0018] As shown in Fig. 2(a), the first thread part 24 is formed by two threads starting at 180° intervals at the upper end part. In this embodiment, the first thread part 24 is a two-thread thread, but according to the height of the threaded wall part 8, it can be a multi-thread thread of three or more threads.

[0019] The mounting part 4 is such that the upper wall 7 is continuously provided with the lower part of the threaded wall part 8 at the inner peripheral edge. At the lower part of the upper wall 7, an outer cylinder 5 and an inner cylinder 6 are vertically provided. On the inner periphery of the outer cylinder 5, a locking reduced-diameter part 27 that engages with the locking protrusion strip 2 to prevent the mouth part 1 from coming off is provided. Multiple stoppers 28 are provided on the upper surface of the upper wall 7 in the circumferential direction. As shown in Figure 2, a first contact surface 28a is formed substantially perpendicular to the unscrew direction, and a first inclined surface 28b is formed in the screw-in direction.

[0020] At the lower outer circumference of the mounting portion 4 (outer cylinder 5), connecting portions 30 of the locking plate portion D are provided from two opposing locations as a separation mechanism. A weakening groove 29 is recessed in the inner circumference of the outer cylinder 5 near one of the inner sides of each connecting portion 30 (in this embodiment, the right side when viewed from below as shown in Figure 3(b)), extending upward from the lower end and including a locking diameter reduction portion 27, so that the outer cylinder 5 in that portion can be broken.

[0021] As shown in Figure 2(a), the locking plate portion D consists of connecting portions 30 extending radially from two opposing locations on the lower outer circumference of the outer cylinder 5, and flange portions 31 formed with a gap from the outer circumference of the outer cylinder 5 in a clockwise direction from the outer edge of the connecting portions 30. Near the right side of each connecting portion 30 of the flange portion 31, notches 32 are cut out from the outer circumference to the inner circumference, and a breakable portion 33 is formed on the inner circumference side of the flange portion 31 where the notches 32 are cut out.

[0022] Each flange portion 31 has a display section 34 on its upper left side when viewed from each notched portion 32, which displays the word "OPEN". Furthermore, a projection 35 is erected adjacent to the left side of the display section 34. When viewed from above, the projection 35 is formed in the shape of an isosceles triangle, with the apex corner 35a on the display section 34 side and extending from the apex corner 35a toward the opposite inner and outer corners 35b. Furthermore, the projection 35 has a fitting recess 36 on its lower side, with parallel surface portions 35c recessed therein, extending parallel to each other from the corners 35b on both sides, leaving a distance α between them. The area around the corners 35b on both sides that remain above the fitting recess 36 is an undercut portion 37.

[0023] Furthermore, as shown in Figure 3(b), the flange portion 31 has through holes 38 drilled on both sides below the undercut portions 37 on both sides of each projection 35, which, as will be described later, penetrate through the mold during molding in the same shape as the undercut portions 37 when viewed from below.

[0024] As shown in Figures 1, 4, and 5, the lid C consists of a screw cap C1 that screws onto the cap body B, and a flange-shaped sealing portion C2 connected via multiple breakable weakening connecting pieces 42 intermittently arranged on the lower outer circumference of the screw cap C1.

[0025] The screw cap C1 comprises a disc-shaped top wall 40 and an outer peripheral wall 41 extending vertically from the outer peripheral edge of the top wall 40. On the inner surface of the top wall 40, a cutting cylinder portion 43 and a screw cylinder portion 44 are attached vertically from the inside out. Furthermore, a sound-producing member 45 is disposed between the cutting cylinder portion 43 and the screw cylinder portion 44. The sound-producing member 45 has a vibrating piece at its tip, and when the lid C is tightened onto the cap body B, the vibrating piece touches and moves over the sound-producing projection 11 of the cap body B, thereby emitting sound, which allows the user to know when the lid C has been tightened.

[0026] The upper inner circumference of the cutting cylinder portion 43 is provided with the same number of second teeth 47 that engage with the first teeth 18, and the lower inner circumference of the cutting cylinder portion 43 is formed with a second engaging projection 46 that engages with the first engaging projection 19 of the cap body B. Furthermore, the outer circumference of the cutting cylinder portion 43 is formed to contact the inner surface of the dispensing cylinder 10, thereby sealing the dispensing outlet.

[0027] The screw cylinder portion 44 is provided with a second screw portion (female thread) 50 on its inner circumference that overcomes and screws onto the first screw portion 24 of the cap body B from above. A wedge-shaped recess 51 that engages with the stopper 28 is provided circumferentially on the lower end surface of the screw cylinder portion 44.

[0028] The wedge-shaped recess 51 has a second contact surface 51a that is substantially perpendicular to the unscrew direction and a second inclined surface 51b that is perpendicular to the screwing direction, and these shapes correspond to the first contact surface 28a and the first inclined surface 28b of the stopper 28, respectively. Note that the sound-producing mechanism consisting of the sound-producing projection 11 and sound-producing member 45, as well as the stopper 28 and wedge-shaped recess 51, are optional.

[0029] The sealing portion C2 is connected via a plurality of breakable weakening connecting pieces 42 arranged on the lower outer edge of the outer peripheral wall 41 of the screw cap C1, and also includes a sealing flange portion 55 whose lower surface abuts against and covers the upper surface of the flange portion 31 of the locking plate portion D of the cap body B when the lid C is set on the cap body B.

[0030] The sealing flange portion 55 has two opposing openings: a through-hole 56 which is roughly isosceles triangular in shape, into which the projection 35 of the flange portion 31 of the locking plate portion D is inserted when the lid C is first set on the cap body B, causing at least the upper part to protrude upward from the fitting recess 36; and a guide opening 57 which is opened by inner and outer arc portions 57a extending in parallel arcs with a width of approximately α from the left side of the through-hole 56 as seen in Figure 4(a), and an end portion 57b connecting the ends of both arc portions 57a. Furthermore, an indicator body 58 with an arrow or the like indicating the direction of opening is provided near the end portion 57b of the guide opening 57 on the upper surface of the sealing flange portion 55.

[0031] The guide opening 57 has locking projections 59 that protrude from the inner ends 57b of the arc portions 57a on both sides, at a distance approximately the same lateral length as the parallel surface portion 35c of the projection 35. The area from the locking projections 59 towards the end 57b is designated as the locking opening 60, and the area from the locking projections 59 towards the through-hole 56 is designated as the display opening 61. Furthermore, the lateral length of the display opening 61 is formed to be at least approximately the same as the lateral length of the display portion 34 of the flange portion 31 of the locking plate portion D, so that the display portion 34 can be seen through the display opening 61 at the same position.

[0032] Next, the usage and effects of this embodiment will be described. First, in manufacturing the dispensing cap of this embodiment, the cap body B has through holes 38 of the same shape drilled in the flange portion 31 below the undercut portions 37 of each projection 35. Therefore, the mold splitting mechanism can be changed to an upper and lower punching mechanism in which a lower mold is provided for the shape of the through holes 38 and an upper mold is provided for molding the projections 35. This allows the shape to be clearly formed without forcibly punching out the undercut portions 37, making manufacturing easier.

[0033] To attach the dispensing cap to the container body A after molding, the lid C is pushed in from the top of the cap body B, setting the cap body B and lid C together, and then the annular groove of the mounting part 4 of the cap body B is placed against the opening 1 of the container body A and the cap is pressed in.

[0034] When setting the lid C from the top of the cap body B, the cutting cylinder portion 43 of the screw cap C1 of the lid C is placed on the dispensing cylinder 10 of the cap body B, the second teeth 47 of the cutting cylinder portion 43 are engaged with the first teeth 18 of the cylindrical wall 16 of the transition plug 15, and the projections 35 of the flange portion 31 of the locking plate portion D of the cap body B are positioned below the through-holes 56 of the sealing flange portion 55 of the sealing portion C2.

[0035] From this state, when the lid C is pushed onto the cap body B, the second threaded portion 50 of the screw cap C1 slides over the first threaded portion 24, and the threaded cylindrical portion 44 of the screw cap C1 fits into the threaded wall portion 8 of the cap body B. As the push-in progresses further, the second engaging projection 46 of the cutting cylinder portion 43 overcomes the first engaging projection 19 of the transition plug body 15 and fits onto the outer surface of the enlarged diameter portion 22, and the wedge-shaped recess 51 at the bottom of the screw cylinder portion 44 fits onto the stopper 28 on the upper wall 7 of the cap body B, and the lid C is set on the cap body B with the screw cylinder portion 44 of the screw cap C1 and the screw wall portion 8 of the cap body B screwed together.

[0036] At the same time, the sealing portion C2 is set such that the projection 35 of the flange portion 31 of the locking plate portion D of the cap body B is inserted into the through-hole 56 of the sealing flange portion 55, and finally, as shown in Figures 1 and 6(a), the sealing flange portion 55 covers the upper surface of the flange portion 31, and the undercut portion 37 at the top of the projection 35 protrudes above the through-hole 56.

[0037] Next, to use the container fitted with the dispensing cap of this embodiment, grasp the screw cap C1 of the lid C and rotate it in the opening direction relative to the cap body B, thereby unscrewing the second threaded portion 50 of the screwed cylindrical portion 44 of the screw cap C1 and the first threaded portion 24 of the screwed wall portion 8 of the cap body B, and opening the lid while raising the screw cap C1.

[0038] When the lid C is rotated, the rotational force of the lid C is applied to the transition plug 15 via the first teeth 18 of the cap body B, which it contacts, along with the rotation of the second teeth 47 of the cutting cylinder portion 43. At this time, the second engaging projection 46 of the cutting cylinder portion 43 engages with the first engaging projection 19 of the cylindrical wall 16, generating an upward force that pulls the transition plug 15 upward as it rotates.

[0039] As the lid C rotates, the rotational force and lifting force applied to the transition stopper 15 cause the thin-walled weakened portion 14 of the cap body B to break, opening the spout. The transition stopper 15, separated from the dispensing cylinder 10, is then lifted up by the cutting cylinder portion 43 that engages with the cylindrical wall 16 and rises together with the screw cap C1 of the lid C.

[0040] Furthermore, as the lid C rotates, the sealing portion C2, which is connected to the screw cap C1 by the weakened connecting piece 42, also rotates. Even if the sealing portion C2 rotates together with the screw cap C1, the locking plate portion D of the cap body B does not rotate, and the projection portion 35 does not move. As shown in Figure 6(b), the inner surfaces of the inner and outer arc portions 57a of the guide opening 57 of the sealing flange portion 55 of the sealing portion C2 abut against the parallel surface portions 35c of the fitting recess 36, which are separated by a distance α on both the inner and outer sides of the projection portion 35, and are guided by them. At the same time, the lower surfaces of the inner and outer undercut portions 37 of the projection 35 contact the upper surface near the arc portion 57a ​​of the sealing flange portion 55, guiding it so as not to come off, and the sealing portion C2 rotates along the upper surface of the locking plate portion D.

[0041] Finally, as shown in Figure 6(c), the projection 35 overcomes the locking projection 59 inside the guide opening 57 and contacts the end portion 57b, and the lower surfaces of the undercut portions 37 on both sides contact the upper surface near the arc portion 57a ​​of the sealing flange portion 55, so that the projection 35 is locked inside the locking opening 60 of the guide opening 57 so that it does not come off upwards. Furthermore, when viewed from above, the indicator 58 of the sealing portion C2 is close to the projection 35, and the indicator 34 of the locking plate portion D is located below the indicator opening 61 of the guide opening 57 of the sealing portion C2, so that the indicator 34 can be seen through the indicator opening 61.

[0042] When the projection 35 of the flange portion 31 abuts against the end portion 57b of the guide opening 57 and is locked inside the locking opening 60, the sealing flange portion 55 of the sealing portion C2 fits with the flange portion 31 of the locking plate portion D, preventing it from rotating. Furthermore, as the screw cap C1 rotates, the sealing flange portion 55 of the sealing portion C2 is prevented from rotating, causing the weakening connecting piece 42 that connects to the sealing flange portion 55 to break, and the screw cap C1 rises, leaving the sealing portion C2 behind.

[0043] As described above, when the lid C is opened, the screw cap C1 rises relative to the cap body B, while the sealing part C2 engages with the locking plate part D of the cap body B, preventing it from rotating. As a result, the weakening connecting piece 42 breaks, and the sealing part C2 remains on the locking plate part D. Furthermore, when the screw cap C1 is rotated, the threaded cylinder portion 44 of the screw cap C1 and the threaded wall portion 8 of the cap body B are disengaged, and the screw cap C1 is opened. Along with the screw cap C1, the contents of the container body A can be dispensed from the opening of the dispensing tube 10 of the cap body B from which the transition stopper 15 has been removed.

[0044] Even if the screw cap C1 is closed onto the cap body B again, as shown in Figure 6(c), the sealing portion C2 is locked in place with the projection 35 of the locking plate portion D fitted into the locking opening 60 of the guide opening 57. Therefore, in addition to the broken state of the weakening connecting piece 42 that connected the screw cap C1 and the sealing portion C2, the proximity of the indicator body 58 and projection 35 of the sealing portion C2, and the indicator body 34 visible through the indicator opening 61 of the sealing portion C2 allow for a quick visual confirmation that the lid C has been opened.

[0045] After using the container, the screw cap C1 is screwed onto the cap body B, causing the outer circumference of the cut cylindrical portion 43 of the screw cap C1 to contact the inner circumference of the dispensing cylinder 10, thereby resealing the inside of the container. When screwing is complete, the sound-emitting member 45 comes into contact with the sound-emitting projection 11 and vibrates, emitting a sound, so that the closing of the dispensing cap can be confirmed. In addition, the wedge-shaped recess 51 at the bottom of the screw cylinder portion 44 of the screw cap C1 fits into the stopper 28 on the upper wall 7 of the cap body B, stopping the screwing, thus preventing the cap from being overtightened and becoming impossible to open.

[0046] After the initial opening, the sealing flange portion 55 of the sealing portion C2 is fitted over the upper surface of the flange portion 31 of the locking plate portion D of the cap body B, so the upper surface of the locking plate portion D is not exposed. This prevents the weakening groove 29 of the cap body B from being cut and detached from the container body A by contacting the flange portion 31 of the locking plate portion D and breaking the break portion 33 during container use.

[0047] In this embodiment, when disposing of the dispensing cap after the container has been used, insert your finger between the sealing flange portion 55 of the sealing portion C2 and the flange portion 31 of the locking plate portion D shown in Figure 1, and while pinching the right end of the notch portion 32 of the flange portion 31, break the break portion 33 downwards. By pulling further, you can pull the lower end of the outer cylinder 5 of the cap body B upwards via the connecting portion 30 connected to the opposite side, causing the weakened groove 29 portion of the outer cylinder 5 to break from below.

[0048] When the weakened groove 29 of the outer cylinder 5 breaks and is pulled, the engagement between the locking diameter reduction portion 27 near the weakened groove 29 of the cap body B and the locking projection 2 of the container body A can be released, allowing the cap body B to be easily detached from the container body A and disposed of separately. In this embodiment, the flange portion 31 of the locking plate portion D is formed with a uniform thickness. However, as seen in Figure 2(a), the flange portion 31 near the right side of the notch portion 32 may be made thinner than the other parts to make it easier to insert a finger between the sealing portion C2 and the locking plate portion D when separating and disposing of the waste. In this embodiment, the outer diameters of the flange portion 31 of the locking plate portion D and the sealing flange portion 55 of the sealing portion C2 are set to be the same. However, the outer diameter of the flange portion 31 of the locking plate portion D may be made larger than the outer diameter of the sealing flange portion 55 of the sealing portion C2 to make it easier to grip the flange portion 31.

[0049] In this embodiment, the locking plate portion D forms a flange portion 31 with a gap between it and the outer circumference of the outer cylinder 5. However, it is also acceptable to form a breakable weakened portion along the outer circumference of the outer cylinder 5 without a gap, which is continuous with the notched portion 32. [Industrial applicability]

[0050] The dispensing cap of the present invention is suitable for use with containers of food, beverages, and condiments that require maintaining a sealed state before use. This is because, by simply rotating the lid in the opening direction, the sealing portion detached from the lid is securely locked to the cap body, allowing the display portion of the cap body to be visible through the display opening of the sealing portion, making it immediately clear whether the cap is open based on the state of the sealing portion.
