Description

  The present invention relates to a mixing cap that is attached to a mouth portion of a container filled with a main agent and can take out an auxiliary agent filled in a portion cup and mix it into the container.

  Conventionally, it can be attached to the mouth of a container as a mixing cap that is attached to the mouth of a container filled with the main agent and can take out the auxiliary agent filled in the portion cup at any timing and mix it with the main agent in the container. A mixing cap composed of a cap body and an outer lid capable of accommodating a portion cup filled with an auxiliary agent is known from Patent Document 1. The mixing cap known in Patent Document 1 includes an opening cutter (cutter 60) for opening a portion cup on the top plate portion of the cap body, and a pressing rib (score breaking protrusion 55) that can open the top plate portion of the cap body. Rotate the outer lid (upper lid 2) that accommodates the portion cup with the opening surface (seal foil 3d) facing down and is screw-engaged with the upper surface of the cap body. The top rib of the cap body is opened by pushing the pressing rib (score breaking protrusion 55) with the outer lid (upper lid 2), and the opening surface of the potion cup that descends while rotating with the outer lid (upper lid 2) ( By rotating and opening the sealing foil 3d) with an opening cutter (cutter 60) provided on the top plate portion, the auxiliary agent filled in the portion cup is dropped into the container and the main agent and It is intended to focus.

  Patent Document 2 also proposes a mixing cap capable of taking out the auxiliary agent filled in the portion cup at any timing and mixing it with the main agent in the container. The mixing cap known in Patent Document 2 has an opening cutter (cut piece 42) extending radially from the radial center of a cap body (second member 4) formed in a cylindrical shape. The upper part of the second member 4) is engaged with a portion cup (first member 2) with the opening surface (blocking piece 8) facing downward, and the portion cup (first member 2) is pushed in.

Japanese Patent No. 4485869 Japanese Patent No. 5893951

However, the mixing cap known in the above-mentioned patent documents still has room for improvement. That is, when the opening surface (seal foil 3d, closing piece 8) of the portion cup (first member 2) is a film, the opening surface (seal foil 3d, closing piece 8) of the portion cup (first member 2) Depending on the contact state between the opening cutter and the opening cutter (cutter 60, cutting piece 42), the opening cutter (cutter 60, cutting piece 42) does not sufficiently bite into the opening surface (sealing foil 3d, closing piece 8), and the opening surface The surface of the (sealing foil 3d, closing piece 8) is gradually stretched while being pressed, and the opening surface (sealing foil 3d, closing piece 8) of the portion cup (first member 2) may not be reliably opened. It was.
Further, before the outer lid (upper lid 2) and the portion cup (first member 2) are sufficiently lowered, the opening surface (sealing foil 3d, closing piece 8) of the portion cup (first member 2) begins to be opened. Therefore, the potion opened from the gap between the outer lid (upper lid 2) and the cap body (second member 4) and the gap between the portion cup (first member 2) and the cap body (second member 4). There was a risk that the secondary agent in the cup (first member 2) would leak out of the container.

Furthermore, in the mixing cap known from Patent Document 1, the top surface of the cap body is opened by pressing the pressing rib (score breaking protrusion 55) with the outer lid (upper lid 2). Since the piece 55) is provided radially outward from the portion cup, the force required to push in the pressing rib (score breaking protrusion 55) increases, and the top plate portion of the cap body does not open easily. Therefore, there was a possibility that the secondary agent would not easily fall into the container from the opened portion cup.
Further, in the mixing cap known from Patent Document 2, a limiting piece for limiting the lowering of the portion cup (first member 2) before opening is provided on the portion cup (first member 2). Protrudes outward in the radial direction from the cylindrical cap body (second member 4), so it is necessary to pay attention to the circumferential direction of the mixing cap at the time of conveyance, and unexpectedly the protruding restriction piece There was a risk of touching and breaking the restricting piece except at the time of opening.

  The present invention solves these problems, and with a simple configuration, the opening surface of the portion cup can be sufficiently opened, and the mixing cap and the outside of the container equipped with the mixing cap are kept hermetically sealed, It is an object of the present invention to provide a mixing cap capable of quickly dropping and mixing the auxiliary agent taken out from the opened portion cup to the main agent side in the container.

  The mixing cap of the present invention is a mixing cap that is attached to the mouth portion of a container filled with a main agent and can take out the auxiliary agent filled in the portion cup and mix it into the container. And the cap body is configured to be engageable with the container mouth portion, and has a top plate portion and a cylindrical protrusion extending upward from the top plate portion, and the top plate A closing plate, a breaking score surrounding the closing plate, and an opening cutter extending upward are provided at a position on the upper surface of the portion facing the opening surface of the potion cup. An outer lid top surface configured to be engageable with the main body, a cylindrical wall extending downward from the outer lid top surface and capable of being included in the cylindrical protrusion, and the cylindrical wall extending downward from the outer lid top surface An outer lid wall portion formed outwardly, and The wall is configured to accommodate the portion cup, and the adapter is configured to engage the cylindrical wall and hold the portion cup, and has a main portion having an opening, and the main portion. A pressing rib extending downward from the portion, the pressing rib can press the closing plate, and the opening has an opening into which the opening cutter can enter, thereby solving the problem. Is.

According to the mixing cap of the first aspect, the adapter is provided with the pressing rib and the opening extending downward, the closing plate of the cap body is pressed with the pressing rib, and the opening cutter is the opening of the adapter. The cap body closing plate and the opening surface of the potion cup can be opened with separate members by the pressing rib provided on the adapter and the opening cutter provided on the cap body. Can be opened with a small force.
In addition, the secondary agent that falls after the portion cup is opened can reliably fall into the container through the opening and the top plate that is opened when the closing plate is pushed down.

  According to the configuration of the second aspect, a push-up rib extending upward is provided at the center of the upper surface of the top plate portion, and the opening of the adapter includes an opening provided so that an opening cutter can enter, and a push-up Since the rib includes an opening provided to allow entry, pushing up the center of the opening surface of the potion cup eliminates the loosening of the opening surface of the potion cup uniformly in the circumferential direction, making the opening cutter even more It is possible to easily bite into the opening surface of the potion cup and to more reliably increase the opening area of the opening surface of the potion cup that has been bitten by the opening cutter.

According to the structure of Claim 3, since the opening cutter is intermittently arrange | positioned in multiple numbers in the position facing the opening surface edge part of a potion cup, when opening a potion cup, a potion cup The opening surface of the opening is formed with a broken-line hole at the edge of the opening surface by the opening cutter, and further, the opening surface is pushed up by the push-up ribs, so that cracks propagate from the broken-line hole and are connected to each other. An opening through which the agent easily passes can be formed.
In addition, since the auxiliary rib is provided on the same circumference as the opening cutter, the opening surface where the broken-line holes are connected to each other by the push-up rib is not formed by the auxiliary rib from the center in the radial direction. By pushing up in the direction of the auxiliary rib, the opening surface can be opened more widely.
Furthermore, it is possible to prevent debris on the opening surface from being mixed into the container.

According to the configuration of the fourth aspect, the cylindrical sealing wall portion extending downwardly provided on the outer lid is formed on the side surface of the cylindrical protrusion of the cap body when the outer lid and the cap body are engaged. Because it makes contact over the entire circumference, the gap between the outer lid and the cap body is always closed from before opening until after opening, so that the side agent in the potion cup does not leak out of the container, and the main agent in the container Even if the admixture is shaken and mixed, the contents will not leak out of the container.
According to the configuration described in claim 5, since the breaking score has an opening start corner near the contact portion between the pressing rib and the closing plate, the opening score is opened when the closing plate is pressed by the pressing rib. By concentrating the stress at the starting point, variations in the breaking mode of the breaking score are unlikely to occur, and the closing plate can be opened more reliably.

According to the configuration described in claim 6, since the outer lid is configured to be rotatable relative to the adapter, even if the outer lid and the cap body are screw-engaged, the outer lid is rotated. When descending to the cap body side, the adapter does not rotate and can be lowered with the position of the opening of the adapter and the opening cutter aligned.
According to the structure of claim 7, since the direction restriction guide that engages with the adapter is provided on the inner peripheral surface of the cylindrical protrusion, when the outer lid is rotated and lowered to the cap body side, The position can be lowered reliably without shifting the positional relationship between the opening of the adapter and the opening cutter.

  According to the configuration described in claim 8, since the cap body and the outer lid are provided with the retaining portions in the direction in which the outer lid is detached from the cap body, the outer lid is completely lowered, and the portion cup After mixing the auxiliary agent in the container and the main agent in the container, when removing the contents from the container, the entire cap can be removed from the container without causing the outer lid and the cap body to come off unexpectedly. Even when the cap is re-sealed in the container, the outer lid and the cap body are not accidentally detached, and the inside of the container can be reliably sealed.

According to the structure of Claim 9, since the raising rib is formed in the flat form extended upwards from the center of a top-plate part, it is local so that the opening surface of a portion cup is directly torn with a raising rib. It can be pushed up without force.
In addition, a plurality of opening cutters are intermittently arranged in a circumferential shape at positions facing the opening surface edge of the portion cup, and the auxiliary ribs are on the same circumference as the opening cutters on the top plate portion. Because it is provided at a position that intersects with the extension line of the plane, it is connected by propagating the cracks in the broken-line holes formed on the opening surface of the portion cup by the opening cutter by pushing it up with the lifting rib. The opening surface of the portion cup is lifted upward by the push-up rib, tilted in the direction of the auxiliary rib, and further pushed up by the auxiliary rib, so that the opening surface can be opened more widely.
In addition, the closing plate is provided inside each of the plurality of opening cutters arranged on the circumference, on both sides of the push-up rib, and the breaking score is provided on the outer peripheral edge of the closing plate. The closing plate can open large without interference.
Further, the plurality of pressing ribs extend downward with different lengths, and when the adapter and the top plate part come into contact with each other, each of the pressing ribs comes into contact with the inside of the different breaking scores. For example, when opening two closing plates Since the pressing force is concentrated on the long pressing rib, one of the closing plates is opened first, and then the pressing force is concentrated on the short pressing rib and the other closing plate is opened. The pressure can be lowered.

At the lower end of the sealing wall portion 134, a diameter-enlarged portion 135 that is radially increased outward is provided, and at the inner peripheral surface of the outer lid wall portion 136, a cap body engaging screw 138 is provided.
In addition, a locking protrusion 139 that protrudes downward and engages with the cap body 110 is provided between the sealing wall portion 134 and the outer lid wall portion 136 in the outer lid top surface 131.

As shown in FIG. 4, the adapter 140 includes a main portion 141 formed in a flat plate shape, two pressing ribs 145 a and 145 b that project in an arc shape from the lower surface of the main portion 141 and extend downward, and an edge of the upper surface of the main portion 141. And an engaging protrusion 146 protruding intermittently from the portion.
The main portion 141 has a central opening 142, an arc-shaped opening 143 intermittently disposed so as to surround the central opening 142, and is intermittently disposed at an edge of the main portion 141 and is opened outward in the radial direction. And a notch 144 is provided.

The central opening 142 is formed with a size and an arrangement through which the push-up rib 112 can pass, and the arcuate opening 143 is formed with a size and an arrangement through which the opening cutter 113 and the auxiliary rib 114 can pass, The notch 144 is formed with a size and an arrangement through which the direction regulation guide 128 can pass.
The two pressing ribs 145a and 145b are arranged on the same circumference, but are formed to have different lengths in the protruding direction, and the pressing rib 145a is longer than the pressing rib 145b.
The pressing ribs 145a and 145b are sized and arranged so that they can pass inside the two closing plates 115a and 115b formed on the top plate portion 111 of the cap body 110 (inside the breaking score 116).

  As shown in FIG. 1, the portion cup 200 contains the secondary agent S, the opening is sealed with a film-like opening surface 201, and a flange-like flange 202 is arranged radially outside the opening. It is formed towards the direction.

Next, the assembly of the mixing cap 100 will be described based on the state immediately before use in FIGS. 1 and 5.
First, the engagement protrusion 146 of the adapter 140 is engaged at the position over the flange 202 from the opening surface 201 side of the portion cup 200.
Next, the portion cup 200 is inserted into the cylindrical wall 132 of the outer lid 130. At this time, the portion cup 200 and the adapter 140 are engaged with the outer lid 130 by engaging the bulging portion 133 of the cylindrical wall 132 so as to be sandwiched between the flange 202 and the engagement protrusion 146.
Furthermore, the outer lid 130 in which the portion cup 200 and the adapter 140 are engaged is screw-engaged with the cap main body 110 in which the container engaging screw 121 is screw-engaged with the container mouth portion 300.
At this time, the pressing ribs 145a and 145b of the adapter 140 sandwich the flat plate surface of the lifting rib 112 of the cap body 110, and are arranged so that the direction restricting guide 128 passes through the notch 144, so that the outer lid Even if 130 rotates, the adapter 140 does not rotate relative to the cap body 110 because the direction regulating guide 128 is contained in the notch 144.

In addition, the outer lid engaging screw 129 and the cap main body engaging screw 138 are screw-engaged until the positioning rib 137 of the outer lid 130 is located between the retaining ring 126 of the cap main body 110 and the positioning convex portion 127. By doing so, the outer lid 130 is simply fixed in position by the positioning rib 137 sandwiched between the retaining ring 126 and the positioning convex portion 127, so that the cap body 110 and the outer lid 130 are not used when the mixing cap 100 is used. , And the mis-opening of the portion cup 200 and the mixing cap 100 due to vibration during transportation can be prevented.
The sealed wall portion 134 of the outer lid 130 is accommodated so that the enlarged diameter portion 135 is in close contact with the inner peripheral surface of the cylindrical protrusion 124 of the cap body 110.

Next, the mixing procedure of the auxiliary agent S in the portion cup 200 and the main agent in the container by the mixing cap 100 will be described based on FIG.
First, when the container is fixed and the outer lid 130 is rotated clockwise, the positioning rib 137 gets over the positioning convex portion 127 as shown in the procedure 1 of FIG. Descent.
The adapter 140 is lowered in the same manner as the outer lid 130, and the pressing rib 145a contacts the vicinity of the opening start corner 117 of the closing plate 115a.
At this time, the adapter 140 and the potion cup 200 together with the outer lid 130 are lowered along the direction regulation guide 128 without rotating, the push-up rib 112 passes through the central opening 142, and the opening cutter 113 passes through the arc-shaped opening 143. Each abuts against the opening surface 201 of the portion cup 200.

Further, the pressing rib 145a presses the closing plate 115a downward, so that the stress is concentrated on the opening start corner portion 117, and the breaking score 116 is broken from the opening start corner portion 117.
Along with the breakage, the closing plate 115a gradually falls downward with the vicinity of the root of the push-up rib 112 as the rotation center, passes through the central opening 142 and arcuate opening 143 where the secondary agent S is opened, and enters the container from the closing plate 115a. A flow path to enter is formed.
Further, when the outer lid 130 is rotated clockwise to lower the adapter 140 and the portion cup 200, the push-up rib 112 pushes up the opening surface 201 to eliminate the slackness of the film, and the opening cutter 113 uses the opening surface 201. The adsorbent S leaks out of the portion cup 200 little by little, and begins to enter the container through the formed flow path.

Since the pressing rib 145b is shorter than the pressing rib 145a, the pressing rib 145b comes into contact with the closing plate 115b and starts pressing after the closing plate 115a starts opening or completely opens.
As described above, since the pressing force from the pressing rib 145 is concentrated on the one closing plate 115 and opened, the pressing force required for opening the closing plate 115 can be lowered.

When the outer lid 130 is further rotated clockwise to lower the adapter 140 and the portion cup 200, the opening surface 201 is lifted upward by the push-up rib 112 as shown in step 2 of FIG. Cracks in a plurality of broken holes provided by the cutter 113 are propagated and connected.
At this time, the opening surface 201 near the auxiliary rib 114 is not cracked by the opening cutter 113 so that the opening surface 201 lifted by the lifting rib 112 is completely removed from the portion cup 200. Since it is pushed into the auxiliary rib 114 side without detachment and is further turned up by the auxiliary rib 114, there is no possibility that the unsealing surface 201 falls into the container, the portion cup 200 opens widely, and the auxiliary agent S is opened to the portion cup. It becomes easy to flow out of 200.
Further, immediately before the outer cover 130 is rotated clockwise, the locking projection 139 climbs the ratchet blade-like slope of the separation preventing projection 125 and gets over the separation preventing projection 125, and the outer lid 130 rotates. After the tightening, the locking projection 139 is located in the vicinity of the right side of the separation preventing projection 125 when viewed from the center side of the cylindrical projection 124.

Similarly to the pressing rib 145a, the pressing rib 145b presses the closing plate 115b downward, and drops downward with the vicinity of the root of the lifting rib 112 as the rotation center. Thereby, the auxiliary agent S flowing out from the portion cup 200 can be quickly put into the container.
The enlarged diameter portion 135 of the sealing wall portion 134 is in close contact with the inner peripheral surface of the cylindrical protrusion 124, and the outer ring 118 and the inner ring 119 are in close contact with the upper end of the container mouth portion 300. When the agent S and the main agent in the container are mixed, even if the entire container is swung together with the mixing cap 100, the content does not leak out from the gap of the mixing cap 100 during mixing.

After mixing the auxiliary agent S with the main agent in the container, the mixing cap 100 is removed from the container mouth part 300 as shown in the procedure 3 of FIG.
At this time, when the outer lid 130 is rotated counterclockwise, the outer lid 130 operates so as to be detached from the cap body 110. However, the locking protrusion 139 is caught by the separation preventing projection 125, so that the cap body 110 together with the outer lid 130 is operated. Also rotates counterclockwise, so that the entire mixing cap 100 moves in a direction to detach from the container mouth portion 300, and the mixing cap 100 can be detached from the container mouth portion 300, and the auxiliary agent S and the main agent are mixed. The contents can be taken out.
At this time, since the tamper evident ring 122 is caught by the container mouth part 300, the weakened part 123 is broken and detached from the skirt wall 120 and remains in the container mouth part 300.

As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment, A various design change can be made without deviating from this invention described in the claim. Is possible.
