Description

  The present invention relates to a cartridge containing an additive to be mixed into a content such as a liquid contained in a container.

  As disclosed in the following Patent Documents 1 and 2, an additive (usually powder or liquid) to be added to the contents (usually liquid) contained in the container is contained in the lid, It has been proposed to configure so that an additive contained in the lid can be discharged and mixed into the contents in the container by appropriately operating the lid when consuming the contents.

JP 2003-292013 A Japanese Patent Laying-Open No. 2005-088997

  Thus, the conventional proposal as described above has the following problems to be solved. First, because the storage part for storing the additive is integrally formed in the lid itself, once the additive is discharged and mixed into the contents of the container, the entire relatively expensive lid is reused. It becomes impossible and not economical. Secondly, the lid is also used as a normal lid to seal the mouth and neck of the container, and therefore keeps being attached to the mouth and neck of the container. There is a tendency that the moisture derived from the permeation passes through the part defining the housing portion of the lid and the additive is deteriorated by moisture.

  In order to solve the problem as described above, the present inventor previously accommodated in a container in the specifications and drawings of Japanese Patent Application Nos. 2011-28889, 2011-28890, and 2011-28891 relating to the applicant's application. A cartridge that contains an additive to be mixed into the contents, and that can be easily discharged into the contents of the container using the repeatedly used lid body as an auxiliary tool. Proposed. Such a cartridge is composed of a first member for containing contents and a second member provided with a cutting means. The first member has an upper surface wall and a cylindrical side wall depending from the peripheral edge of the upper surface wall, and a lower surface is opened, and a cut is attached to the lower surface of the container and closes the lower surface. And after the additive is accommodated in the container, the obstruction piece is attached to the lower surface of the container. The second member is composed of a cylindrical body whose upper surface and lower surface are open, and a cutting means is disposed at the inner lower portion of the cylindrical body. The cutting means is composed of a plurality of cutting pieces having inclined cutting edges inclined downward in the radial direction from the tip located at the center of the cylindrical body, and the plurality of cutting pieces are equiangularly spaced. It is placed and arranged. When the first member is lowered relative to the second member, the cutting means of the second member acts on the closing piece of the first member to cut the closing piece. An annular bottom wall extending radially inward is disposed at the lower end portion of the inner peripheral surface of the cylindrical body, and a plurality of arc shapes projecting upward at intervals in the circumferential direction on the upper surface of the bottom wall. Pieces are disposed, and each of the arcuate pieces is located between two adjacent pieces in the circumferential direction. Further, a sealing ring is provided on the upper surface of the bottom wall so as to protrude upward radially outward from the arc-shaped piece. The projecting height of the arc-shaped piece is larger than the projecting height of the ring, and the first member is the first member. When lowered relative to the second member, the lower end of the side wall of the container is positioned between the inner peripheral surface of the cylindrical body and the ring, and the outer peripheral surface of the ring is inserted into the container through the closing piece. It is brought into close contact with the outer peripheral surface of the lower end portion of the side wall.

  Thus, the cartridge proposed by the inventor is not sufficiently satisfactory. According to the inventor's experience, when the tip of the cutting blade acts on the closing piece, the closing piece expands and bends. For example, it is not always easy to cut the closing piece, and in some cases, a considerable force is required.

  The present invention has been made in view of the above-mentioned facts, and the main technical problem thereof is that the cartridge previously proposed by the present inventor is further improved so that the closing piece is sufficiently easily and excessively applied by the cutting blade. It is to be able to cut without need.

The present inventors have conducted extensive studies results, a plurality of cut pieces constituting the cutting means, inclined downward toward the radially outwardly from the inner end located in the center, and then radially outwardly to the outer tip The present inventors have found that the main technical problem can be achieved by forming an inclined cutting edge that is inclined upward.

That is, according to the present invention, as a cartridge that achieves the main technical problem, a cartridge composed of a first member that contains an additive and a second member that includes a cutting means,
The first member has an upper surface wall and a cylindrical side wall depending from the peripheral edge of the upper surface wall, and a lower surface of the container is opened, and the lower surface of the container is attached to the lower surface to close the lower surface and a cutting occluded pieces,
The second member is composed of a cylindrical body having an upper surface and a lower surface opened, and a cutting means is disposed at an inner lower portion of the cylindrical body.
The cutting means has a plurality of inclined cutting edges that are inclined downward radially outward from an inner tip located at the center of the cylindrical body and then inclined upward radially outward to the outer tip. The plurality of cut pieces are arranged at equiangular intervals, and
When the first member is lowered relative to the second member, the cutting means of the second member acts on the closing piece of the first member to cut the closing piece. To
A cartridge is provided.

  Preferably, the inner tip and the outer tip of the cutting piece are at the same height. It is preferable that three to eight cut pieces are arranged at equiangular intervals. An annular bottom wall extending radially inward is disposed at the lower end portion of the inner peripheral surface of the cylindrical body, and the ring protrudes upward on the bottom wall radially outward from the cutting piece. It is desirable that the upper edge of the ring has a corrugated shape in which the portion that aligns with the cut piece in the circumferential direction is the lowest and the intermediate portion between adjacent cut pieces is the highest. When the first member is lowered relative to the second member, the lower end of the side wall of the container is positioned between the inner peripheral surface of the cylindrical body and the ring, Conveniently, the outer peripheral surface of the ring is brought into close contact with the inner peripheral surface of the lower end portion of the side wall of the container through the closing piece.

  In the cartridge of the present invention, when the first member is lowered relative to the second member, each of the cutting pieces acts on the closing piece from the two tips of the inner tip and the outer tip. Thus, the loosening of the closing piece is effectively suppressed, and thus the closing piece can be cut with the cutting blade sufficiently easily and without requiring excessive force.

  3 and 5 together with FIG. 1, the second member 32 of the cartridge 28 includes a cylindrical body 54 having an upper surface and a lower surface opened. Four supported ridges 55 are formed on the outer peripheral surface of the cylindrical body 54 so as to protrude in the radial direction at equal intervals in the circumferential direction. An annular bottom wall 56 extending inward in the radial direction is formed at the lower end portion of the inner peripheral surface of the cylindrical body 54. As clearly shown in FIG. 5, an annular seal piece 57 protruding downward is formed on the lower surface of the bottom wall 56. The cylindrical body 54 protrudes downward beyond the bottom wall 56. A ring 60 protruding upward is also formed on the upper surface of the bottom wall 56. Cutting means 64 is further disposed on the bottom wall 56. In the illustrated embodiment, a plurality of, in the illustrated case, four radiating pieces 62 extending from the radial center to the inner periphery of the bottom wall 56 are provided. A cutting piece 66 constituting the cutting means 64 is formed on the upper surface of each radiation piece 62. Each of the cutting pieces 66 includes a sharp inner tip 68 located at the center of the cylindrical body 54, a sharp outer tip 70 positioned radially outward from the inner tip 68, and a radially outward direction from the inner tip 68 downward. It is important to have a sharp sloped cutting edge 72 that slopes inward and then extends upwardly and radially outwardly to the outer tip 70. In the illustrated embodiment, the cutting means 64 is composed of four cutting pieces 66 arranged at equal angular intervals of 90 degrees, but if desired, two, three, or five or more The cutting means 64 can also be comprised from a cut piece. Preferably, the cutting means 64 is composed of 3 to 8 cut pieces arranged at equal angular intervals. The inner tip 68 and the outer tip 70 in each of the cutting pieces 66 can have different heights, but are preferably the same height. As clearly understood by referring to FIGS. 1 and 5, the upper half of each of the cutting pieces 66 is gradually increased in width downward. As clearly understood by referring to FIGS. 1 and 4, the upper edge of the ring 60 has a wave shape, and its height is the lowest at a portion aligned with the cutting piece 66 in the circumferential direction, and the adjacent cutting. It is highest in the middle part of the piece 66.

  On the inner peripheral surface of the cylindrical body 54, a plurality of, in the illustrated case, four locking protrusions 73 are provided that protrude radially inward at equal intervals in the circumferential direction. As clearly shown in FIG. 6, one end surface (clockwise front end surface in FIG. 6) 74 of the locking projection 73 is an upright surface that forms an angle of approximately 90 degrees with respect to the inner peripheral surface of the cylindrical body 54. The other end surface (clockwise rear end surface in FIG. 6) 76 of the locking projection 73 is a gentle arcuate surface. As will be apparent from the following description, the locking protrusion 73 cooperates with the arc-shaped protrusion 42 formed on the housing 34 of the first member 30 and the first protrusion 44 and the second protrusion 46. Constitutes locking means; On the inner peripheral surface of the cylindrical body 54, a plurality of, in the illustrated case, four arcuate locking pieces 78 projecting in the radial direction at intervals in the circumferential direction below the locking projections 73 are also arranged. It is installed. As clearly shown in FIG. 6, each of the arc-shaped locking pieces 78 extends forward in the clockwise direction in FIG. 6 with respect to each of the locking protrusions 73.

FIG. 7 shows the lid body 2 that can be used in combination with the cartridge 28 described above. A lid body 2 that can be injection-molded from an appropriate synthetic resin such as polypropylene or polyethylene is composed of a cylindrical main portion 4 and an outer lid 6 connected to the main portion 4. If it demonstrates with reference to FIG. 8 with FIG. 7 , the upper surface and lower surface of the main part 4 will be opened. An annular locking groove 8 is formed at the upper end of the outer peripheral surface of the main portion 4. On the outer peripheral surface of the main portion 4, a large number of projections 10 extending from a portion slightly below the locking groove 8 to the lower end are formed at intervals in the circumferential direction. As clearly shown in FIG. 7 , the upper end portion of the protrusion 10 is omitted at a specific angle portion, and a smooth surface 12 having no protrusion is formed at the specific angle portion at the upper end portion of the outer peripheral surface of the main portion 4. ing. As clearly shown in FIG. 8, a female thread 14 is formed at the lower end portion of the inner peripheral surface of the main portion 4. An annular support ridge 16 projecting radially inward is formed at the axially intermediate portion of the inner peripheral surface of the main portion 4.

  The outer lid 6 of the lid body 2 has a circular top wall 18 and a cylindrical side wall 20 depending from the periphery of the top wall 18. The outer lid 6 is connected to the upper end of the main portion 4 via a hinge mechanism 22 so as to be openable and closable, on the opposite side in the diameter direction with respect to the smooth surface 12 in the main portion 4. The hinge mechanism 22 may be of a form well known to those skilled in the art, and the outer lid 6 is pivotally opened and closed between an open position shown in FIG. 7 and a closed position shown in FIG. When the outer lid 6 is shown in the open position shown in FIG. 7, the upper surface of the main portion 4 is opened, and when the outer lid 6 is shown in the closed position shown in FIG. 8, the main portion 4 is opened. The upper surface is covered with the outer lid 6. An arc-shaped protruding piece 24 is formed on the lower end portion of the outer peripheral surface of the side wall 20 on the opposite side in the diametrical direction with respect to the hinge mechanism 22 (therefore, the position corresponding to the smooth surface 12 of the main portion 4). As clearly understood by referring to FIG. 8 together with FIG. 7, three locking protrusions 26 are arranged at equal intervals in the circumferential direction at the lower end portion of the inner peripheral surface of the side wall 20. When the outer lid 6 is brought into the closed position shown in FIG. 8, the locking protrusion 26 engages with the locking groove 8 of the main portion 4, and thereby the outer lid 6 is maintained in the closed position so as to be releasable. . In the illustrated embodiment, the outer lid 6 is connected to the main portion 4 via the hinge mechanism 22, but if desired, an outer lid is formed separately from the main portion 4, and this outer lid is attached to the main portion 4. It is also possible to cover the opened upper surface of the main part 4 by detachably attaching to the upper end part.

  Next, the usage mode of the cartridge 28 described above will be described. The container 34 in the first member 30 of the cartridge 28 is turned upside down, that is, the opened lower surface is directed upward, and the container 34 may have an additive (not shown) that may be powder or liquid. To accommodate. Next, the closing piece 36 is joined to the lower end of the side wall 40 of the container 34 to close the lower surface of the container 34. Thereafter, the first member 30 and the second member 32 are combined to form the cartridge 28. More specifically, as shown in FIG. 5, the first member 30, that is, the container 34 in which the closing piece 36 is joined to the lower surface through the opened upper surface of the cylindrical body 54 constituting the second member 32. The lower part is inserted into the cylindrical body 54. At this time, the four arc-shaped protrusions 42 formed on the lower end of the container 34 are positioned between the four locking protrusions 73 formed on the inner peripheral surface of the cylindrical body 54, and are thus locked. The arc-shaped protrusion 42 is positioned below the locking protrusion 73 by passing between the protrusions 72. The insertion of the container 34 into the cylindrical body 54 is restricted by the restriction piece 50 disposed in the container 34 coming into contact with the upper end of the cylindrical body 54, and the arcuate protrusion 42 of the container 34 is formed in the cylindrical body 54. It is positioned below the locking protrusion 73 formed on the inner peripheral surface of the, but is positioned above the arcuate locking piece 78. Next, the container 34 is rotated clockwise or counterclockwise with respect to the cylindrical body 54 as viewed from above. As can be clearly understood by referring to FIG. 6, the first protrusion 44 disposed in the container 34 is disposed in the cylindrical body 54 because the both side surfaces of the first protrusion ridge 44 are erected surfaces. The two protrusions 46 disposed in the container 34 have a relatively small protrusion amount and the tip end surface is arcuate in cross section. The locking projection 73 is in contact with and locked to the one end surface 74, but is elastically beyond the other end surface 76 without being locked to the gentle other end surface 76 of the locking projection 73. It rides on the stop protrusion 73 and can get over the stop protrusion 73. Therefore, as understood by referring to FIG. 6, the rotation of the container 34 relative to the cylindrical body 54 is caused by the arc-shaped protrusion 42 disposed on the container 34 being disposed on the cylindrical body 54. It is made to stop in the state located under the latching protrusion 73 currently made. In this state, when the container 34 is displaced upward with respect to the cylindrical body 54, the arc-shaped protrusion 42 contacts the locking protrusion 73, and thus the upward displacement of the container 34 is prevented. On the other hand, the container 34 is prevented from separating upward. When the limiting piece 50 of the container 34 abuts the upper end of the cylindrical body 54, the arc-shaped protrusion 42 of the container 34 is positioned somewhat above the arc-shaped locking piece 78 of the cylindrical body 54. As shown in the drawing, the container 34 is slightly inclined with respect to the cylindrical body 54, and one of the arc-shaped protrusions 42 is brought into contact with one of the arc-shaped locking pieces 78. The cartridge 28 composed of the first member 30 and the second member 32 is combined in the state shown in FIG. 5 and sealed and packaged in a bag (not shown) composed of a synthetic resin film, for example. Sold.

  A typical consumption mode when a consumer who purchases the cartridge 28 consumes the additive contained in the container 34 is as follows. First, the breakable connecting portion 48 attached to the side wall 40 of the container 34 in the first member 30 of the cartridge 28 is broken to remove the limiting piece 50. As a result, as shown in FIG. 8, the slight inclination of the first member 30 with respect to the second member 32 is eliminated, and the four arc-shaped protrusions 42 of the container 34 have four arc-shaped engagements of the cylindrical body 54. It is brought into contact with the stop piece 78. Thereafter, the outer lid 6 of the lid body 2 is moved to the open position shown in FIG. 7, and the cartridge 28 is inserted into the main portion 4 through the upper surface where the main portion 4 is opened as shown in FIG. The cartridge 28 is inserted into the main portion 4 when the supported ridge 55 formed on the outer peripheral surface of the cylindrical body 54 abuts on the support ridge 16 formed on the inner peripheral surface of the main portion 4. Further, the pair of limiting pieces 52 formed on the upper end portion of the outer peripheral surface of the side wall 40 of the container 34 are limited by contacting the upper end edge of the main portion 4. Next, the outer lid 6 of the lid body 2 is moved to the closed position shown in FIG. On the other hand, for example, a container lid (see FIG. 9) attached to a mouth and neck portion 80 (FIG. 9) of an appropriate container containing a liquid content such as natural water, for example, a container made of polyethylene terephthalate. Only the tamper evidence skirt 82 is shown), and only the tamper evidence skirt 82 is left and detached from the mouth and neck 80. A male thread 84 and a locking jaw 86 positioned below the male thread 84 are formed on the outer peripheral surface of the mouth-and-neck part 80 of the container which may be in a known form. The container lid has a top wall and a skirt wall depending from the periphery of the top wall, and the skirt wall is formed with a circumferential break line, and the skirt wall has a main portion above the circumferential break line. A tamper-evidence skirt 82 below the circumferential break line is defined, and a female thread that is screwed into the male thread 84 of the mouth-and-neck 80 is formed on the inner peripheral surface of the main part of the skirt wall. The tamper-evident hem 82 has an inner peripheral surface formed with a locking means that is locked to the locking jaw 86 of the mouth-and-neck part 80. When the mouth-and-neck part 80 is opened, the circumferential direction breaks. The line may be broken.

  Next, as shown in FIG. 9, the lid body 2 containing the cartridge 28 is fitted on the mouth and neck portion 80, and the lid body 2 is rotated clockwise as viewed from above in FIG. 9. The female thread 14 formed at the lower end of the inner peripheral surface of the portion 4 is screwed into the male thread 84 of the mouth-and-neck section 80. When the lid body 2 is lowered with respect to the mouth-and-neck portion 80 as the screwing of the female thread 14 and the male thread 84 progresses, the lower surface of the cylindrical body 54 constituting the second member 32 of the cartridge 28 is moved. The disposed seal piece 57 enters the mouth / neck portion 80, and the lower end of the bottom wall 56 of the cylindrical body 54 is brought into contact with the top surface of the mouth / neck portion 80. The cartridge 28 is prevented from further lowering. When the lid body 2 descends with respect to the mouth and neck portion 80 and the lid body 2 is lowered to the position illustrated in FIG. 9, the inner surface of the top wall 18 of the outer lid 8 of the lid body 2 is the first of the cartridge 28. The member 30 is brought into contact with the upper surface wall 38 of the container 34.

  If the lid body 2 continues to rotate and the lid body 2 continues to descend with respect to the mouth and neck portion 80, the second member 32 of the cartridge 28 is prevented from further descending with respect to the mouth and neck portion 80. The first member 30 of the outer lid 2 is forcibly moved downward along with the lowering of the lid body 2 by forcing the top wall 18 of the outer lid 2 downward of the upper wall 38 of the container 34. Accordingly, the container 34 is forcibly lowered with respect to the cylindrical body 54, and the arc-shaped protrusion 42 of the container 34 elastically rides over the arc-shaped locking piece 78 of the cylindrical body 54. As clearly understood by referring to FIG. 10, when the container 34 is lowered with respect to the cylinder 54, the cutting means 64 of the cylinder 54 is joined to the lower end of the side wall 40 of the container 34. The closed piece 36 is cut by acting on the closed piece 36. More specifically, each of the cutting pieces 66 constituting the cutting means 64 starts to act on the closing piece 36 from the inner tip 68 and the outer tip 70 that are located in the radially separated positions, thereby sufficiently relaxing the closing piece 36. Therefore, the closing piece 36 is broken into a cross shape easily and without requiring an excessive force. When the container 34 is lowered to the position illustrated in FIG. 10 with respect to the cylindrical body 54, the inner peripheral surface of the lower end portion of the side wall 40 of the container 34 is moved through the closing piece 36 displaced upward. The outer peripheral surface of the ring 60 is brought into close contact with the outer peripheral surface of the ring 60, thereby sealing the outer peripheral edge of the lower end of the container 34. As shown in FIG. 10, the closing piece 36 cut by the cutting means 64 is guided upward by the ring 60 and displaced upward, thereby generating a discharge path leading from the inside of the container 34 to the mouth / neck portion 80 of the container. The additive contained in the container 34 is mixed into the contents contained in the container. The upper edge of the ring 60 has a wave shape, and its height is the lowest at the portion aligned with the cutting piece 66 in the circumferential direction and the highest at the intermediate portion between the adjacent cutting pieces 66, so that the closing piece 36 is reliably cut. And smoothly guided upward.

  After substantially all of the additive contained in the container 34 is discharged and mixed into the contents contained in the container, the lid body 2 is counterclockwise as viewed from above in FIG. And the male screw 84 and the female screw 14 are gradually disengaged, and the lid body 2 and the cartridge 28 accommodated therein are detached from the mouth-and-neck portion 80 of the container. The cartridge 28 removed from the lid body 2 with the outer lid 6 of the lid body 2 in the open position is discarded without being reused, but the lid body 2 is further reused in combination with another new cartridge 28. be able to. On the other hand, with respect to the contents contained in the container and containing the additive, if necessary, the container lid separated from the mouth-and-neck part 80 with only the tamper-evidence hem 82 remaining is removed again. After the mouth-and-neck part 80 is temporarily sealed after being attached to 80, the container is shaken appropriately to mix the contents sufficiently with the contents, and then the container lid is removed from the mouth-and-neck part 80 and then consumed.
