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 mix an auxiliary agent 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 an inner lid and a portion cup filled with an auxiliary agent is known from Patent Document 1.
The mixing cap known in Patent Document 1 has an opening cutter (cut piece 42) extending radially from the center in the radial direction 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. The opening surface (blocking piece 8) is cut by the opening cutter (cutting piece 42), and the secondary agent filled in the portion cup (first member 2) is dropped into the container and mixed with the main agent. is there.

Japanese Patent No. 5893951

However, the mixing caps known in the above-mentioned patent documents still have room for improvement.
That is, in order to take out the contents from the container after the auxiliary agent in the portion cup (first member 2) has been mixed with the main agent, it is necessary to remove the inner lid (second member 4) from the container mouth. For example, there is a possibility that the container cannot be opened / closed quickly in a use environment such as shampoo or seasoning that is frequently used with one hand and water or foreign substances are likely to enter the container.
In addition, when the contents in the container are a high-viscosity stock solution, when the contents are taken out by removing the inner lid (second member 4) from the container mouth, the contents adhere to the outer peripheral surface of the container mouth. The inner lid (second member 4) may not be easily attached to the container mouth.

Further, since the opening surface (blocking piece 8) of the portion cup (first member 2) begins to be opened before the portion cup (first member 2) is sufficiently lowered, the portion cup (first member 2). There was a risk that the secondary agent in the opened portion cup (first member 2) would leak out of the container from the gap between the container and the inner lid (second member 4).
Moreover, although the restriction piece which restrict | limits the fall of the portion cup (1st member 2) before opening is provided in the portion cup (1st member 2), a restriction piece is a cylindrical inner lid (2nd Since it protrudes outward in the radial direction from the member 4), it is necessary to pay attention to the circumferential direction of the mixing cap at the time of conveyance, and the protruding restriction piece is abruptly touched. Could break.

  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, A mixing cap that can quickly drop the adjunct removed from the opened potion cup to the main agent in the container for mixing, and dispense the mixed contents without removing the mixing cap from the mouth of the container. Is intended to provide.

  The mixing cap of the present invention is a mixing cap that is attached to the mouth of a container filled with the main agent and can mix the auxiliary agent into the container. The mixing cap includes an outer lid and an opening cutter. A holding space capable of holding a portion cup having a lid and a sealing surface that can be sealed while holding the filled secondary agent, and the outer lid is engageable with the inner lid and is rotatable relative to the inner lid. An outer lid top surface, a cylindrical wall extending downward from the outer lid top surface, and an outer lid wall portion extending outward from the cylindrical wall and extending downward from the outer lid top surface. An intermediate wall portion formed between the cylindrical wall and the outer lid wall portion that extends downward from the outer lid top surface, and the outer lid top surface is more circumferential than the cylindrical wall. A holding hole that is located outward in the direction and penetrates the top surface of the outer lid, and a sealing cover that can open and close the pouring hole is provided, Between, it is configured to be able to accommodate the portion cup on the inner peripheral side of the cylindrical wall, the intermediate wall portion is provided with a hanging piece extending downward from the lower end of the intermediate wall portion, It is configured to be engageable with the container mouth portion, and has a top plate portion, and a cylindrical protrusion that extends upward from the top plate portion and can be engaged with the inside of the outer lid wall portion. A through-hole penetrating the top and bottom of the top plate portion and communicating with the container mouth portion is provided, and an anti-rotation portion bulging radially inward on the inner peripheral surface of the cylindrical projection, and the rotation A drop restricting portion having an upper end surface lower than the preventing portion, and one of the rotation preventing portions and one of the drop restricting portions are adjacent to each other, and the other of the rotation preventing portions and the drop restricting portion A drop guiding portion is formed between the other, the rotation preventing portion, the drop regulating portion, and the front When the outer lid and the inner lid are engaged with each other, the drop guiding portion is configured to be positioned on the same circumference as the lower end of the hanging piece, and the hanging piece is configured to open the upper lid. After rotating to a position that matches the drop guiding portion in the circumferential direction, the upper lid is configured to be movable up and down relative to the inner lid, and the opening cutter is opposed to the opening surface of the portion cup of the top plate portion. The above-mentioned problem is solved by being provided at the position to be operated.

According to the mixing cap of the invention according to claim 1, the top surface of the outer cap of the mixing cap is provided with the pouring hole penetrating the outer lid top surface and the sealing cover that can open and close the pouring hole. After the auxiliary agent in the mixing cap is mixed with the main agent, the contents in the container can be taken out from the dispensing hole without removing the mixing cap from the container opening by opening the hermetic cover.
In addition, since the holding space is configured so that the portion cup can be accommodated on the inner peripheral side of the cylindrical wall, the shape of the portion cup can be unified even when producing using a plurality of types of auxiliary agents. For example, mixed caps can be produced without the need to change the production line.

Furthermore, since the portion cup already filled with the auxiliary agent is disposed in the holding space, it is possible to prevent the auxiliary agent from adhering to other parts and being contaminated during the assembly operation of the mixing cap.
Moreover, since the secondary agent passes through the through-hole that can communicate with the container mouth portion, it can reliably fall into the container.

Further, a hanging piece extending downward from the lower end of the intermediate wall portion is provided on the intermediate wall portion of the outer lid, and an anti-rotation portion, a drop regulating portion, and a drop are provided on the inner peripheral surface of the cylindrical protrusion of the inner lid. Since the guide part is formed, when the drooping piece comes into contact with the drop restricting part, the outer lid does not fall to the inner cover side as long as the drop restricting part and the drooping piece are in contact. It is possible to prevent the opening surface of the potion cup from coming into contact with the opening cutter.
In addition, on the anti-rotation part side adjacent to the drop restricting part, the drooping piece can prevent the outer lid from rotating, and the outer cover can be rotated to move the drooping piece from the drop restricting part to the drop guiding part side. And by dropping to the drop guiding part, the entire outer lid can fall to the inner lid side, and the opening surface of the portion cup can be opened by the opening cutter formed on the top plate part.

  According to the structure of Claim 2, since a part of outer peripheral surface of a cylindrical wall is non-circular shape which has a diameter-reduced part over the up-down direction, the content which goes to a pouring hole from a container opening part A short flow path can be formed in which the material can easily flow, and the contents in the container can be taken out more efficiently.

  According to the structure of Claim 3, since the outer periphery of the flange provided in the circumference | surroundings of the opening surface of a portion cup is a non-circular shape similar to a cylindrical wall, after opening of an opening surface The flange can be pressed down and fixed stably at the lower end of the cylindrical wall.

According to the configuration of the fourth aspect of the present invention, since the holding rib formed to bulge inward in the radial direction from the lower portion of the drooping piece is provided at the lower portion of the drooping piece, By placing the lower edge, the potion can be held in a stable posture.
In addition, a space can be formed between the top plate portion and the portion cup by the thickness of the holding rib in the vertical direction, and when taking out the contents in the container, the flow path toward the pouring hole is sufficiently blocked with the portion cup. Widely secured.

  According to the structure of Claim 5, since the holding rib is formed so that the flange can be held, by placing the flange of the portion cup before opening on the holding rib, the opening cutter can be used in addition to the time of use. The opening surface can be prevented from being touched and opened, and the flange can be sandwiched between the lower end of the cylindrical wall and the holding rib to be stably fixed, and the opening surface can be reliably opened with an opening cutter during use. Can do.

  According to the configuration of claim 6, the mixing cap forms a first flow path between the portion cup and the top plate portion when the lower end of the holding rib and the top plate portion abut upon opening. When the mixed contents are taken out, the passage from the container mouth to the pouring hole can be shortened without the passage of the contents being blocked by the portion cup, and the contents can be taken out quickly.

  According to the structure of Claim 7, the extraction | pouring hole of an outer cover is formed in the outward of a reduced diameter part, and the 2nd flow path is formed in the outer side of a reduced diameter part and the inner surface of a cylindrical protrusion, Since the extraction hole communicates with the second flow path, the contents flowing into the second flow path from the container mouth can be flowed into the extraction hole with a short flow path, and the contents can be taken out even more efficiently. it can.

  According to the configuration of claim 8, at least one upper surface of the drop restricting portion gradually moves upward from the inner peripheral surface of the cylindrical protrusion toward the central axis side of the cylindrical protrusion, and the lower end of the drooping piece. Since there is an inclined part that can contact the outer peripheral surface of the cylindrical projection, when the drooping piece comes into contact with the drop restricting part, the drooping piece moves radially inward from the drop restricting part and comes out. It can prevent reliably that the whole lid | cover will fall further.

According to the configuration of the ninth aspect, since the opening cutter extends in an arc shape along the outer peripheral edge of the through-hole, the opening cutter can be greatly opened along the edge of the opening surface of the portion cup, and the auxiliary agent Can quickly flow into the through hole.
Also, since the opening surface is gradually inclined downward in the direction of turning up, the opening cutter comes into contact with the opening surface from the opposite side of the opening surface in the direction of turning up and concentrates the opening force. And can be gradually opened in the flip-up direction, and the opening surface can be opened more reliably.

According to the configuration of the tenth aspect, since the top plate portion has the push-up rib extending upward, by pushing up the opening surface of the portion cup, the bending looseness of the opening surface is eliminated, and the opening plate is opened. The cutter can easily bite into the opening surface, and the opening area of the opening surface into which the opening cutter bites can be surely expanded.
Furthermore, since the push-up rib is gradually inclined downward in the direction of turning up the opening surface, it is possible to more reliably eliminate the bending of the opening surface where the opening cutter first contacts, and to open the opening surface. By preventing the push-up rib from coming into contact with another position of the opening surface before the cutting cutter bites into the opening surface, the opening cutter can be easily bited by the opening surface.

In the outer peripheral surface of the cylindrical wall 116, a reduced diameter portion 124 formed in a plane extending in the vertical direction is provided at a position located on the side of the extraction hole 121 when viewed from the central axis of the outer lid 110.
On the inner peripheral surface of the outer lid wall 112, a first temporary fixing rib 113, a second temporary fixing rib 114 provided above the first temporary fixing rib 113, and an upper side than the second temporary fixing rib 114. The retaining ribs 115 provided on the bulges are formed to bulge inward in the radial direction.

The inner lid 130 is configured to be engageable with the container mouth B, and as shown in FIGS. 5 and 6, can be engaged with the top plate portion 131 and the inside of the outer lid wall portion 112 extending upward from the top plate portion 131. A cylindrical projection 134 and a skirt wall 133 extending downward from the top plate portion 131 and screw-engageable with the container mouth portion B.
The top plate portion 131 extends through the top plate portion 131 through the top and bottom of the top plate portion 131 and communicates with the container mouth B. The top plate portion 131 extends upward from the top plate portion 131 and extends in an arc along the outer peripheral edge of the through hole 132. The opening cutter 143 and the inner region surrounded by the opening cutter 143 are provided with push-up ribs 142 extending upward from the top plate portion 131 and radially formed in three directions from the center of the top plate portion 131. Yes.
The lifting rib 142 and the opening cutter 143 are formed so as to be gradually inclined downward toward the opening side of the arc formed by the opening cutter 143.

On the inner peripheral surface of the cylindrical protrusion 134, there are a rotation preventing portion 135 bulging radially inward and a drop restricting portion 136 having an upper end surface lower than the rotation preventing portion 135. The side surfaces are adjacent to each other, and a drop guiding portion 139 is formed between the other side surface of the rotation preventing portion 135 and the other side surface of the drop restricting portion 136.
The rotation preventing unit 135, the drop regulating unit 136, and the drop guiding unit 139 are configured to be positioned on the same circumference as the lower end of the hanging piece 118 when the outer lid 110 and the inner lid 130 are engaged. ing.

At least one upper surface of the upper surface of the drop restricting portion 136 has an inclined portion 137 that gradually moves upward from the inner peripheral surface of the cylindrical protrusion 134 toward the central axis of the cylindrical protrusion 134.
In addition, a reverse rotation prevention portion 138 extending upward is formed on the drop guide portion 139 side of at least one upper surface of the upper surface of the drop restricting portion 136.
A contact ring 140 bulging radially inward is provided at the upper part of the inner peripheral surface of the cylindrical protrusion 134, and bulging outward in the radial direction on the outer peripheral surface of the cylindrical protrusion 134. A locking rib 141 is provided.

As shown in FIG. 7, the portion cup P has an opening surface Ps provided on the lower surface thereof connected to the flange Pf to seal the inside of the portion cup P.
Moreover, the rough shape of the lower surface of the portion cup P has a D-shape in which both ends of the arc are connected by a straight line.

  Next, the assembly of the mixing cap 100 will be described with reference to FIGS.

First, the portion cup P is set in the holding space 120 of the outer lid 110.
At this time, by fixing the flange Pf of the portion cup P at such a position as to be sandwiched between the lower end of the cylindrical wall 116 and the holding rib 119, the portion cup P can be reliably prevented from falling out of the holding space 120. Can be held.

Next, the outer lid 110 into which the portion cup P is inserted is put on the inner lid 130.
At this time, when the outer lid 110 is put on the inner lid 130 so that the cylindrical projection 134 is inserted between the outer lid wall portion 112 and the intermediate wall portion 117, the contact ring 140 on the inner peripheral surface of the cylindrical projection 134 is The outer peripheral surface of the intermediate wall 117 is uniformly contacted in the circumferential direction.
Further, the engaging rib 141 on the outer peripheral surface of the cylindrical protrusion 134 engages so as to be sandwiched between the first temporary fixing rib 113 and the second temporary fixing rib 114 on the inner peripheral surface of the outer lid wall portion 112, and hangs down. The lower end of the piece 118 is in contact with the upper end of the drop restricting portion 136.

By engaging the locking rib 141 between the first temporary fixing rib 113 and the second temporary fixing rib 114, the outer lid 110, the inner lid 130, The relative positional relationship in the up and down direction does not change, and the opening cutter 143 does not touch the opening surface Ps.
Further, in this embodiment, an inclined portion 137 is provided so that the drooping piece 118 does not fall off from the drop restricting portion 136. When the drooping piece 118 comes into contact with the drop restricting portion 136, the drooping piece 118 is inclined. By the portion 137, the lower end of the hanging piece 118 is moved along the inner peripheral surface of the cylindrical protrusion 134.

  Further, when the hanging piece 118 is in contact with the drop restricting portion 136 provided with the reverse rotation preventing portion 138, the outer lid 110 and the inner lid 130 may be affected by impact or vibration to the extent that the mixing cap 100 is transported. Even when a force that shifts the relative positional relationship in the circumferential direction is generated, the drooping piece 118 is restricted in movement by the rotation prevention unit 135 and the reverse rotation prevention unit 138 adjacent to the drop regulation unit 136. It is possible to prevent the drooping piece 118 from unexpectedly falling to the drop guiding portion 139.

Next, a mixing procedure and a dispensing procedure of the auxiliary agent S of the portion cup P and the main agent in the container by the mixing cap 100 will be described based on FIGS. 11 to 15.
For the sake of explanation, the containers shown in the figure are all upright.

First, as shown in FIGS. 11 and 12, the mixing cap 100 is attached to the container mouth B, and the outer lid 110 is rotated clockwise.
Since the outer lid 110 rotates relative to the inner lid 130, when the outer lid 110 is rotated, the drooping piece 118 gradually moves toward the drop guiding portion 139 adjacent to the drop regulating portion 136.

At this time, since the side surface of the reverse rotation prevention portion 138 on the drop restricting portion 136 side is formed with an inclined surface that goes from the inner peripheral surface of the cylindrical projection 134 toward the radially inner side as it advances in the clockwise direction, The drooping piece 118 moves toward the drop guiding portion 139 while being deformed inward in the radial direction so as to avoid the reverse rotation preventing portion 138 by the force of rotating the 110.
In addition, since the side surface of the anti-reverse portion 138 on the drop guide portion 139 side is formed by a plane extending radially inward from the inner peripheral surface of the cylindrical protrusion 134, the drooping piece 118 has crossed over the anti-reverse portion 138. Thereafter, even if the outer lid 110 is rotated counterclockwise, the drooping piece 118 cannot get over the reverse rotation preventing portion 138, and the relative positional relationship between the outer lid 110 and the inner lid 130 in the circumferential direction is changed. I can't do it.

When the outer lid 110 is pushed in after the drooping piece 118 is moved onto the drop guiding portion 139, the drooping piece 118 moves to the lowermost end of the drop guiding portion 139 as shown in FIGS. 110 is moved to the inner lid 130 side, and the opening cutter 143 bites into the opening surface Ps to form a plurality of broken-line cracks. Begin to enter.
As will be described later, when the outer lid 110 is pushed in here, a space is formed in the height direction in the top plate portion 131 and the flange Pf by the height of the holding rib 119, and the first flow path when the contents M are taken out. L1.

Further, a second flow path L <b> 2 communicating with the extraction hole 121 is formed on the outer side of the reduced diameter portion 124 and the inner surface of the cylindrical protrusion 134.
At this time, the locking rib 141 moves over the second temporary fixing rib 114 and the retaining rib 115 and moves above the retaining rib 115. As a result, the outer lid 110 can be prevented from moving away from the inner lid 130.

Further, since the lifting rib 142 and the opening cutter 143 are formed so as to be gradually inclined downward toward the opening side of the arc formed by the opening cutter 143, the opening cutter of the opening surface Ps. It is possible to more reliably eliminate the bending at the position where 143 first comes in contact, making it easier for the opening cutter 143 to bite into the opening surface Ps, and concentrating the force for opening the opening surface Ps by the opening cutter 143 at one point. The opening surface Ps can be opened more reliably.
While the outer lid 110 is pushed into the inner lid 130 side, the unsealing surface Ps is completely unsealed by the unsealing cutter 143, and all the secondary agent S flows into the container.

  At this time, since the contact ring 140 is in close contact with the outer peripheral surface of the intermediate wall 117 in the circumferential direction, the outer lid 110 and the inner lid 130 even if the container is shaken when the auxiliary agent S and the main agent are mixed. The auxiliary agent S and the main agent do not leak out of the container.

  Next, the content M obtained by mixing the auxiliary agent S with the main agent in the container is taken out.

As shown in FIG. 15, by opening the sealing cover 122 of the outer lid 110, the pouring hole 121 of the outer lid top surface 111 is opened.
When the container is tilted toward the pouring hole 121, the content M passes through the through hole 132 from the container mouth B, passes through the first flow path L1 formed between the top plate 131 and the flange Pf, and is cylindrical. It goes to the pouring hole 121 through the second flow path L2 outside the wall 116.

At this time, the potion cup P holds the flange Pf at the position separated from the top plate portion 131 by the height of the holding rib 119 because the position of the flange Pf is fixed by the lower end of the cylindrical wall 116 and the holding rib 119. When one flow path L <b> 1 is formed and the lower end of the drop guide portion 139 is raised from the top plate portion 131, it is held at a position further away from the top plate portion 131.
Further, on the outer peripheral surface of the cylindrical wall 116, a reduced diameter portion 124 formed in a plane extending in the vertical direction is provided at a position located on the side of the extraction hole 121 when viewed from the central axis of the outer lid 110. Therefore, it is possible to ensure a sufficiently wide flow path for the content M from the through hole 132 to the extraction hole 121.

As a result, the contents M can be taken out without removing the mixing cap 100 from the container mouth B, and the contents M can be easily taken out with one hand. It is possible to suppress foreign matter from entering the inside.
In addition, since the contact ring 140 of the inner lid 130 is in close contact with the inner peripheral surface of the intermediate wall portion 117, the content M does not leak from between the cylindrical protrusion 134 and the intermediate wall portion 117.
