Therefore, the number of articles constituting the container lid is two points, that is, the cap body and the upper lid, and the assembly can be easily performed.

  In addition, in the stage before the sealing foil is ruptured, the top plate portion of the cap body is not formed with a passage into the container of the additive for mixing that flows out from the ruptured sealing foil, and the sealing foil ( Alternatively, the annular pressing member is lowered by turning the upper lid holding the sealing foil (the flange portion of the portion cup to which the sealing foil is fixed) in the closing direction, and the sealing foil is broken by the cutter. As the abutting member is lowered, the score breaking protrusion provided in the pouring region of the top plate portion of the cap body is pushed down, and the breaking score forming the pouring region is broken. A passage is formed into the container for the mixing additive that flows out of the foil. That is, the passage is not formed unless the lower lid is turned in the closing direction after the lowering regulation band provided on the upper lid is cut off. Therefore, the formation of such a passage does not cause a problem in the sealing function of the container lid.

The present invention will be described below in detail with reference to the accompanying drawings.

FIG. 5 is a bottom view of the cap body of the mixing container lid in FIG.
6 is a side view of a half section of the cap body of the mixing container lid in FIG. 1 (section AA in FIG. 3);
FIG. 7 is a diagram showing a two-liquid mixing process of the mixing container lid of FIG.
FIG. 8 is a side sectional view showing another example of the mixing container lid of the present invention.

  Referring to FIGS. 1 and 2, the mixing container lid of this aspect of the present invention comprises a cap body as indicated by 1 as a whole and an upper lid as indicated by 2 as a whole. The upper lid 2 accommodates a portion cup 3 filled with an additive for mixing to be mixed with the liquid in the container (see FIG. 1). Screws are attached.

  2 and 3 to 6, the cap body 1 has a top plate portion 5 and a skirt-like side wall 7 that descends downward from the periphery of the top plate portion 5. A screw 8 is formed on the inner surface of the skirt-shaped side wall 7, and the screw body 8 is screw-engaged with a screw 81 formed on the outer surface of the container mouth portion 80, whereby the cap body 1 is placed in the container. Attached to the mouth 80. Further, on the outer surface of the skirt-like side wall 7, as shown in FIGS. 4 and 6, for preventing slipping, the cap body 1 can be smoothly turned for opening and closing. Knurls (or knurls) 9 are formed.

  An inner ring 10 is formed on the lower surface of the top plate portion 5 at a distance from the skirt-like side wall 7. When the cap body 1 is screw-engaged with the container mouth portion 80, the upper end of the container mouth portion 80 is A good sealing performance is ensured by entering the space between the ring 10 and the skirt-like side wall 7 and the outer surface of the inner ring 10 being in close contact with the inner surface of the container mouth 80. In this case, it is preferable to form an outer ring 11 between the inner ring 10 and the skirt-shaped side wall 7, and the inner surface of the outer ring 11 is in close contact with the outer surface of the container mouth 80, thereby providing a sealing property. Can be increased. The outer ring 11 is preferably formed with notches 11a at appropriate intervals. If such a notch 11a is formed, when the internal pressure of the container rises and the top plate portion 5 is domed (swelled), gas is vented through the notch 11a, and the cap jumps due to the increase of the internal pressure of the container. Such inconveniences can be reliably prevented. Further, it is advantageous to form a small protrusion 13 between the outer ring 11 and the inner ring 10 in order to further improve the sealing performance. That is, the small protrusion 13 abuts on the upper end surface of the container mouth 80 that has entered between the inner ring 10 and the outer ring 11 by screw engagement, functions as an auxiliary seal, and can further improve the sealing performance. .

  A tamper evidence band (TE band) 17 is preferably provided at the lower end of the skirt-like side wall 7 via a breakable bridge 15 as necessary. The TE band 17 has, for example, a locking piece 17a such as a flap piece on the inner surface. When the cap body 1 is turned in the opening direction, the locking piece 17a is moved along with the rise of the skirt-like side wall 7. Abutting on the lower side of the jaw 83 formed on the outer surface of the container mouth 80, the rise of the TE band 17 is restricted. That is, when the opening is continued, the bridge 15 is broken and the TE band 17 is separated from the cap main body 1, so that a general user can recognize the fact of opening and prevent mischief or container. The quality of the content liquid can be guaranteed.

A cylindrical protrusion 19 is formed on the top surface of the top plate portion 5 of the cap body 1 described above. The cylindrical protrusion 19 has a thread 20 on the outer surface, and the upper lid 2 is attached to the cap body 1 using the thread 20. Further, on the top surface of the top plate portion 5, a ratchet 21 for preventing rotation is formed on the outer side of the cylindrical projection 19 (or on the outer surface of the lower portion of the cylindrical projection 19). The ratchet 21 is prevented (in FIG. 3, indicated by arrow Z ¹⁾ rotation in the plugging direction of the upper lid 2 but permits rotation of the cap removal direction (in FIG. 3, indicated by arrow Z ²⁾ Is to do.

  Returning again to FIG. 1, the upper lid 2 is formed on the upper wall 23, the cylindrical side wall 25 lowered from the periphery of the upper surface wall 23, and the outer circumferential wall 27 extending outward from the lower end of the cylindrical side wall 25. An annular wall 29 for engagement is lowered from the peripheral edge, and a thread 31 that is threadedly engaged with the thread 20 on the outer surface of the cylindrical projection 19 described above is formed on the inner surface of the annular wall 29. Is formed. That is, the upper lid 2 is screwed to the cap body 1 by threadingly engaging the thread 31 on the inner surface of the annular wall 29 with the thread 20 on the outer surface of the cylindrical projection 19 of the cap body 1.

  A lowering restriction band 35 is provided at the lower end of the engagement annular wall 29 via a tearable weakening line 33. When the upper lid 2 is screwed to the cap main body 1, the lowering regulation band 35 has its lower surface abutting against the upper surface of the top plate portion 5 of the cap main body 1, thereby restricting the lowering of the upper lid 5 (engaging annular wall 29). Thus, the closed state of the upper lid 2 is maintained with the lowering restriction band 35 interposed between the lower end of the engaging annular wall 29 and the upper surface of the top plate portion 5 of the cap body 1. That is, in the state where the lowering restriction band 35 exists, a gap is formed between the lower end surface of the circumferential horizontal wall 27 and the upper end surface of the cylindrical protrusion 19 by the amount of the lowering restriction band 35.

  A knob 36 is provided on the outer surface of the lowering regulation band 35. By pulling the band 35 with the knob 36, the weakening line 33 is torn and the lowering regulation band 35 is attached to the upper lid 2 (annular). The upper lid 2 can be further swung in the closing direction and lowered until the lower end surface of the circumferential horizontal wall 27 and the upper end surface of the cylindrical projection 19 come into contact with each other. In this case, a sealing ring 38 is preferably provided on the lower surface of the circumferential horizontal wall 27. That is, when the lower regulating band 35 is cut off and the upper lid 2 is lowered, the sealing ring 38 is brought into close contact with the inner peripheral surface of the upper end portion of the cylindrical projection 19 to improve the sealing performance at this time. it can. Although not shown in the figure, the lowering regulation band 35 is provided with an axial score in the vicinity of the knob piece 36. By pulling the knob piece 36, the axis score is broken, and then the knob piece 36 is removed. The weakening line 33 is torn by rolling in the circumferential direction, whereby the lowering restriction band 35 is cut off.

  Furthermore, a locking projection 37 is provided on the inner surface of the lowering regulation band 35 so as to engage with the ratchet 21 described above when it is rotated in the opening direction. That is, due to the engagement between the locking projection 37 and the ratchet 21, the upper lid 2 cannot be rotated in the direction of opening, and therefore, the upper lid 2 is removed from the cap body 1 unless the lowering restriction band 35 is separated. As a result, excellent tamper evidence can be ensured for the mixing liquid in the portion cup 3 accommodated in the upper lid 2.

  In the present invention, the annular pressing member 39 is provided on the inner peripheral side of the lower surface of the circumferential flange 27 in the upper lid 2, and the inner side space (upper lid) between the cylindrical side wall 25 and the annular pressing member 39 described above. The potion cup 3 is accommodated in the space.

  The portion cup 3 has a body wall 3a, a bottom wall 3b, and a circumferential horizontal flange 3c formed at the upper end of the body wall 3a. The cup 3 is mixed with the container contents. It is filled with an additive and sealed with a sealing foil 3d such as an aluminum foil adhered and fixed to the circumferential flange 3c. That is, as shown in FIG. 1, the portion cup 3 is accommodated in the upper lid space in an inverted state, and the horizontal flange 3 c is held on the lower end surface of the annular pressing member 39. That is, a protrusion 40 is formed on the outer peripheral portion of the lower end surface of the annular pressing member 39, and the portion cup 3 (horizontal flange 3c) is held by the protrusion 40 so as not to fall downward.

  In the present invention, by separating the lowering regulation band 35 and lowering the upper lid 2, the seal foil 3 d is broken and a predetermined liquid flow path is formed in the top plate portion 5 of the cap body 1 as described later. The additive filled in the portion cup 3 can be mixed with the contents of the container. However, in order to break the seal foil 3d and form the additive passage, the top plate portion 5 has the following structure. It is important to have a structure.

  2 to 6 in particular (the cross section of the cap body 1 shown in FIGS. 2 and 4 is the BB cross section of FIG. 3, and the cross section of the cap body 1 shown in FIG. FIG. 3 is a cross-sectional view taken along the line AA in FIG. A pair of pouring regions 50 and 50 are formed with the line X in between. The pouring region 50 includes a root line 51 located on the first center line X side, a break score 53 starting from one end of the root line 51 and ending at the other end. A score breaking protrusion 55 is formed along the inside of the breaking score 53.

  That is, in the casting region 50, the score breaking protrusion 55 is pushed down by the lowering of the upper lid 2 (the lowering of the annular pressing member 39) by separating the lowering restriction band 35 described above, thereby the breaking score. 53 is broken, and as a result, the pouring region 50 is dropped downward with the root line 51 as a fulcrum, and an additive passage is formed.

  Therefore, in order to smoothly form the passage as described above, the root line 51 extends substantially parallel to the first center line, as particularly shown in FIG. It is formed of linear scores 53a and 53a that are connected to both ends of the root line and are parallel to each other, and an arc-shaped score 53b that bulges outward to connect the linear scores 53a and 53a, and for score breaking along the inside of the arc-shaped score 53b It is preferable to form the protruding piece 55. That is, since the lower surface of the annular pressing member 39 that descends while rotating contacts the upper end of the score breaking protrusion 55, the breaking score 53 and the score breaking protrusion 55 are arranged as described above, thereby The score 53 can be broken smoothly.

  Further, as shown in FIG. 2, the thickness of the top plate portion 5 where the breaking score 53 (53a, 53b) is formed is naturally very thin, but the root line 51 is formed. The thickness of the portion that is made is thicker than the breaking score 53 portion, but is preferably thinner than the other portions. That is, by making the thickness of the portion where the root line 51 is formed thin enough not to break, the pouring region 50 can be easily dropped downward with the root line 51 as a fulcrum.

  Further, when the pouring region 50 is dropped downward with the root line 51 as a fulcrum, the additive score flowing from above breaks the linear score 51a, 51a from the central portion (between the root lines 51, 51 in FIG. 2). Flow into the container. Therefore, in order to smooth the flow of such an additive, the shape of the pouring region 50 is changed to a second center line Y that intersects the first center line X at a right angle as shown in FIGS. And the top surface of the top plate portion 5 in the pouring region 50 is an inclined surface 50a (excluding the score breaking protrusion 55) whose ridgeline is the second center line Y serving as the symmetry axis. It is suitable. That is, in the pouring region 50, it is preferable that the portion along the second center line Y is the thickest and has a tapered surface such that the thickness gradually decreases toward the linear score 51a side. As a result, the liquid does not stay on the pouring region 50 and smoothly flows into the container through the portion where the linear scores 51a, 51a are broken.

  Further, in the present invention, since the additive for mixing in the cup 3 is poured into the container through the portion where the linear scores 51a, 51a are broken, it is naturally necessary to break the sealing foil 3d. is there. In order to break such a sealing foil 3d, cutters 60 are formed in the vicinity of the casting regions 50 and 50, respectively.

  As shown in FIG. 6, the cutter 60 has a tapered protrusion at the upper end portion, and as shown in FIG. 2, the height (the position of the upper end) is for score breaking. It is preferable that the height is lower than the protruding piece 55. That is, the upper end of the cutter 60 abuts against the seal foil 3d, and the upper lid 2 descends while rotating in this state, whereby the seal foil 3d is broken, but the cutter 60 is higher than the score breaking protrusion 55. If set, before the passage due to score breakage is formed, the sealing foil 3d breaks, the mixing additive in the portion cup 3 flows out, and the mixing additive is added between the upper lid 2 and the cap body 1 Even if a thing is filled and a passage is formed after that, some additives may not flow into the container and may stay. However, if the height of the cutter 60 is kept low, the passage is formed first, and then the sealing foil 3d is broken, and the inconvenience of the retention of the additive can be surely avoided.

Further, breakage of the sealing foil 3d, since the upper lid 2 is performed while turning to the plugging direction (indicated by Z ¹ in FIG. 3), as shown in FIGS. 2 and 3, the cutter 60 a pair, One cutter 60 is disposed adjacent to one casting region 50, the other cutter 60 is disposed adjacent to the other casting region 50, and the pair of cutters 60, 60 are pointed to each other about the center O of the top plate portion 5. The symmetrical arrangement is suitable for smoothly cutting the seal foil 3d into a circular shape, and further, the tip of the seal foil 3d broken at the upper end of the cutter 60 proceeds smoothly. It is preferable that the upper end 60a of the cutter 60 is tapered so that the height decreases from the side toward the closing direction (see FIG. 2).

  Further, as can be understood from FIGS. 2, 3, and 6, it is preferable to form the guiding regions 62 and 62 so as to be adjacent to both sides of the pair of pouring regions 50 and 50. The guide region 62 is composed of a bank-like protrusion 62b having an inclined surface 62a that is relatively low on the side of the pouring region 50 (see FIG. 6), and in particular, the center between the pair of pouring regions 50, 50. In the part, the height is the highest. By forming the guiding area 62 as described above, the mixing additive (particularly liquid) flowing out from the broken portion of the seal foil 3d can be guided to the pouring area 50 and efficiently introduced into the container.

When forming the guiding region 62 as described above, it is preferable to form the cutter 60 in the region 62, for example, on the inclined surface 62a, as shown in FIG.
Further, as shown in FIG. 5 and FIG. 6, on the lower surface of the top plate portion 5, a lightening portion 62 c is formed at a portion corresponding to the bank-like protrusion 62 b forming the guiding region 62, and the resin It is preferable to reduce the basis weight.

  The mixing container lid of the present invention having the above-described structure is sold in the form shown in FIG. 1, and mixing with the container contents is performed in the process shown in FIG.

  That is, the portion cup 3 filled with a predetermined mixing additive and sealed with the sealing foil 3d is placed in the upper lid 2 so that the circumferential horizontal flange 3c is held by the lower end surface of the annular pressing member 39. The upper lid 2 in which the portion cup 3 is accommodated is attached to the cap main body 1 that is previously attached to the container mouth by screwing, and is provided for sale in the state shown in FIG. In this case, the upper lid 2 in which the portion cup 3 is accommodated can be attached to the cap body 1 and, in this state, attached to the container mouth portion 80.

  Next, when mixing, as described above, by pulling with the knob 36 from the container lid (the annular wall 29 of the upper lid 2) attached to the container mouth 80 as shown in FIG. Separate the descent restriction band 35. Thereafter, the upper lid 2 is swung in the closing direction, and the upper lid 2 is lowered until the lower end surface of the circumferential horizontal wall 27 and the upper end surface of the cylindrical projection 19 come into contact with each other as shown in FIG. Let

  In the above lowering process, first, the lower end surface of the annular pressing member 39 of the upper lid 2 pushes down the score breaking projection piece 55, thereby breaking score 53 (straight score 53a and arc score 53b). Is broken, and the pouring region 50 is dropped downward with the root line 51 as a fulcrum to form an additive passage. Further, after the breaking score 53 is broken, the sealing foil 3 d of the portion cup 3 is broken by the cutter 60. Accordingly, in the state of FIG. 7A, the mixing additive filled in the portion cup 3 flows into the container.

  On the other hand, in the state of FIG. 7A, the sealing ring 38 formed on the lower surface of the circumferential horizontal wall 27 of the upper lid 2 is in close contact with the inner surface of the upper end portion of the cylindrical wall 19 of the cap body 1. The seal is secured. Therefore, in this state, the mixing additive can be uniformly mixed with the container contents by shaking the container for each container lid.

  After mixing is performed as described above, the TE band 17 is cut off as shown in FIG. 7B by turning the cap body 1 in the direction of opening, thereby opening the container mouth 80. The cap body 1 is removed from the container mouth 80 with the upper lid 2 attached, and the container mouth 80 is opened. Therefore, in this state, the contents of the container mixed with the additive can be taken out (or poured out) from the container, or directly taken from the container.

  The mixing container lid of the present invention is not limited to the embodiment shown in FIGS. 1 to 7 described above. For example, the mixing liquid is directly stored in the upper lid 2 without using the portion cup 3. You can also. This embodiment is shown in FIG.

  That is, in the example of FIG. 8, the portion cup 3 is not used, and the additive for mixing is directly filled in the inner space of the annular pressing member 39 and the cylindrical side wall 25. Except for the point that the sealing foil 70 such as an aluminum foil is directly heat-sealed and sealed on the lower end surface, the other structure is exactly the same as the container lid shown in FIGS. That is, the mounting to the container and the mixing process can be performed just like the container lid of FIGS. Of course, in this example, it is not necessary to provide the protrusion 40 on the lower end surface of the annular pressing member 39.

  Moreover, in the example of FIGS. 1-8 mentioned above, the top plate (upper part of the annular wall 29 for engagement) which comprises the upper cover 2 is the upper surface wall 23, the cylindrical side wall 25 which fell from the periphery of the upper surface wall 23, and a cylinder. The outer side wall 27 extends outward from the lower end of the side wall 25 so that a relatively large volume of mixing additive can be accommodated in the upper lid 2. When the amount of the additive may be small, the top plate may be composed of only the flat top wall 23 (that is, the cylindrical side wall 25 may not be formed).

  In the mixing container lid of the present invention described above, the mixing additive may be either liquid or powder.

  In the mixing container lid of the present invention, the cap body 1 and the upper lid 2 are each made of various plastics such as low-, medium- or high-density polyethylene, linear low-density polyethylene, polypropylene, thermoplastic polyester, polyamide, styrene. It is manufactured by integral molding such as injection molding, compression molding or the like using a base resin, ΑΒ S resin or the like. Further, the potion cup 3 is manufactured by the same molding means using the same plastic as described above, and after being filled with a predetermined additive for mixing, heat sealing a sealing foil such as an aluminum foil can be easily performed. Can be manufactured.
