Abstract

<P>PROBLEM TO BE SOLVED: To allow the alteration of a quantity of deformation of a proof-band according to the use of a closing cap. <P>SOLUTION: The closing cap 16 includes: a cap body 44 that screws into a discharging piece 14; a band 46 connected to the cap body 44 by a connecting part 60; and a deformation quantity adjusting means. At least a part of the band 46 has a splitting section 52, which is connected by a connecting piece 54. When the cap body 44 is rotated relative to the discharging piece 14 in the opening direction of the cap, the front of the band 46 in the opening direction of the cap in relation to the connecting piece 54 is rotated together with the cap body 44 while the rotation of the back of the band 46 in the opening direction of the cap is hindered by the engagement of an internal claw formed on the internal circumferential face of the band with the external claw formed on the external circumferential face of the discharging piece 14. Circumferential force is caused to act on the connecting piece 54, thereby breaking the connecting piece 54 and splitting the band in the splitting section 52. Additionally, the deformation quantity adjusting means can adjust a quantity of deformation of the proof-band upon the split of the band. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a closure cap with a tamper-proof function, a mouthpiece unit, and a packaging container provided with the mouthpiece unit, so that it is understood that the mouth has been opened once opened.

  Some packaging containers have a cylindrical pouring piece attached to a pouring outlet for pouring out the contents, and a cap is screwed into the mouth of the pouring piece to close it. In recent years, in order to prevent the contents from being tampered with or the like, such a packaging container with a closure cap often adds a tamper-proof function to the closure cap so that it can be understood that it has been opened once opened. It has become.

  A cap with anti-tampering function has a proof band connected to the cap body, and when the cap is opened, the proof band remains on the dispensing piece side, and when the cap is opened. There is a type in which the proof band remains on the cap side. However, particularly when the packaging container is not used up, in view of hygiene, a type in which the proof band remains on the cap side is preferable to a type in which the proof band remains on the extraction piece side.

  As a type in which a proof band remains on the cap side, for example, Patent Documents 1 to 3 disclose an opening / closing cap with a tamper-proof function that is screwed into a mouth portion of a pouring portion attached to a packaging container. These open / close caps include a cap body that is screwed into the outer peripheral surface of the pouring part, and a band that is provided at the lower end of the cap body so as to extend in the circumferential direction of the open / close cap, and the band includes at least one place in the circumferential direction. And is connected by a connecting piece that can be cut at this position. Further, the band is connected to the lower end surface of the cap body by a connecting piece on the front side of the connecting piece in the opening direction of the opening / closing cap. The pouring portion is provided with a plurality of ratchets, and a claw portion that engages with the ratchet is provided on the inner peripheral surface of the band on the rear side of the connection piece in the opening direction of the opening / closing cap. . When the cap is rotated in the opening direction with respect to the pouring part, the ratchet of the pouring part engages with the claw part of the band and prevents the part of the band located on the rear side of the connecting piece from rotating. On the other hand, since a rotational force acts on the front side of the opening / closing cap in the opening direction from the cap body via the connecting portion, a force in the circumferential direction acts on the connection piece to cut the connection piece. When the connecting piece is cut, the end portion of the band that is not connected to the cap body by the connecting portion is deformed downward. This makes it possible to confirm whether or not the opening / closing cap has been once opened.

  In recent years, even when the opening and closing of the closure cap such as a packaging container containing a seasoning is repeated, the closure cap with tamper prevention has been used. In order to make it clearer that it has been opened, it is preferable to increase the amount of deformation of the proof band after opening the cap. On the other hand, if the contents of the packaging container can be swallowed at a time like a beverage, it is not a problem to increase the deformation of the proof band, but the closure cap can be opened and closed when the contents of the packaging container are seasonings. In a case where the proof band is repeatedly used, a greatly deformed proof band may be in the way, which may inconvenience the user. Therefore, it is desirable to change the deformation amount of the proof band according to the use of the cap.

In the plug unit, the plug cap further includes a deformation amount adjusting means for adjusting a deformation amount of the band when the band is divided.

  In one embodiment, the deformation amount adjusting means is a width in the band circumferential direction of the connecting portion determined according to a use, and increases the deformation amount of the band by reducing the width of the connecting portion. The amount of deformation of the band is decreased by increasing the width of the connecting portion.

On the other hand, a suction port 26 is provided at the lower end of the straw portion 20, and a plurality of elongated holes 28 are formed in the peripheral wall portion of the straw portion 20, so that the contents of the packaging container 12 can be accommodated in these suction ports 26. And it can flow into the straw portion 20 through the long hole 28.

  Between the stopper 24 of the mouth part 18 and the straw part 20, three octagonal plate-like bases 30, 32, 34 extending horizontally outward from the outer peripheral part of the pouring piece 14, An attachment portion 36 that is positioned below and fits into the spout of the packaging container 12 is formed. Of the three pedestals 30, 32, and 34, the one closest to the stopper 24 (the uppermost pedestal 30 in FIG. 1) is provided apart from the stopper 24, and the outer edge is outside the outer edge of the stopper 24. It is formed so that it may be located in. The attachment portion 36 preferably includes a pair of plate-like ear portions 38 that protrude from the outer peripheral portion toward both sides so that the packaging material around the spout of the packaging container 12 can be easily attached. In the space between the stopper 24 and the pedestal 30, a plurality of ribs 40 and 42 extending from the outer peripheral surface of the mouth portion 18 toward the outer edge of the pedestal 30 along the upper surface of the pedestal 30 are provided.

  The pair of ribs 40 extend in the opposite direction from the outer peripheral surface of the mouth portion 18 so that their tips protrude beyond the outer edge of the stopper 24 and are located inside the outer edge of the uppermost pedestal 30.

On the other hand, the pair of ribs 42 extend so as to be point-symmetric with respect to the center of the mouth portion 18 from the intermediate position between the tip end and the base end of the rib 40 and perpendicular to the rib 40, respectively. It protrudes beyond the outer edge of the stopper 24 and is located inside the outer edge of the uppermost pedestal 30. Each of the pair of ribs 42 extends perpendicularly to the rib 40 from an intermediate position between the distal end and the proximal end of the rib 40, and therefore the distal end of the pair of ribs 42 is in the direction opposite to the opening direction (that is, the closing direction). ) And protrudes from the outer edge of the stopper 24. The tips of these ribs 40 and 42 constitute outer claw portions 41 and 43 of the extraction piece 14 that engage with inner claw portions 56 and 58 of the band of the closure cap 16 described later.

  As shown in FIG. 2, the cap 16 has a substantially cup-shaped cap body 44 that is screwed into the mouth portion 18 of the pouring piece 14 to close the cap 18, and a peripheral edge of the mouth portion of the cap body 44. And an annular band 46 disposed adjacent thereto. A spiral female screw 48 is formed on the inner peripheral surface of the cap main body 44, and can be screwed into the male screw 22 formed on the outer peripheral surface of the mouth portion 18 of the extraction piece 14. On the other hand, on the outer peripheral surface of the cap main body 44, a plurality of ribs 50 are provided that are spaced apart at equal intervals in the circumferential direction and each extend in the axial direction so that the cap cap 16 can be easily grasped and rotated. Yes.

  As shown in FIG. 3, the band 46 is provided with a dividing portion 52 at least at one location of the band 46 so as to divide the band 46 in the circumferential direction, and is located with the dividing portion 52 interposed therebetween. The ends in the circumferential direction of the band 46 are connected by the connection piece 54. In the illustrated embodiment, the band 46 is divided into two band portions 46 a and 46 b by two dividing portions 52, and the circumferential ends of the two band portions 46 a and 46 b located between the dividing portions 52. The parts are connected by a connecting piece 54 to form an annular band 46.

  When the capping cap 16 is rotated with respect to the pouring piece 14 in the direction in which the capping cap 16 is removed from the pouring piece 14 (hereinafter referred to as the opening direction) on the inner peripheral surfaces of the band portions 46a and 46b. Inner claw portions 56 and 58 that engage with the outer claw portion 43 of the dispensing piece 14 are formed. The inner claw portions 56 and 58 are bent in the opening direction. In addition, in order to transmit the force which resists rotation of the capping cap 16 from the extraction | suction piece 14 efficiently, the inner side nail | claw parts 56 and 58 are one band part 46a, 46b, as FIG. 3 shows. However, a plurality of (two in the illustrated embodiment) are preferably provided, but only one inner claw portion 56 may be provided for one band portion 46a, 46b. In addition, in order for the force that resists the rotation of the capping cap 16 to efficiently act on the connection piece 54 of the band 46 via the engaging portion between the inner claw portions 56 and 58 and the outer claw portions 41 and 43. The at least one inner claw 56 of the inner claw portions 56, 58 of one band portion 46a, 46b is the rear side in the opening direction of the closure cap 16 with respect to the dividing portion 52 or the connecting piece 54 of the band 46 ( It is preferably provided in the vicinity of the band portions 46a and 46b in the opening direction front end side).

  The cap body 44 and the band 46 are connected by a plurality of connecting portions extending from the periphery of the mouth of the cap body 44 toward the band 46. The connecting portion that connects each of the band portions 46 a and 46 b to the cap body 44 includes a main connecting portion 60 and an auxiliary connecting portion 62. The auxiliary connecting part 62 is thinner and narrower than the main connecting part 60, and the outer claw parts 41, 43 and the inner claw parts 56, When an external force in the circumferential direction is applied to the band 46 through the engaging portion with the belt 58, the band 46 is easily broken. On the other hand, the main connecting portion 60 is provided in the vicinity of the dividing portion 52 (for example, a position separated by 5 ° from the center of the circumferential width of the dividing portion 52 as shown in FIG. 5). Even if a circumferential external force is applied to the band 46 by rotating the cap 14 with respect to the piece 14, it does not break and has a sufficient thickness and width so as to maintain the connection between the cap body 44 and the band 46. Have. As shown in FIG. 2, the main connecting portion 60 has a substantially L shape in a longitudinal section, and extends from the peripheral edge of the mouth of the cap body 44 toward the band in the axial direction of the cap body 44. The upright portion 60a (extending downward in FIG. 2) and the horizontal portion 60b extending substantially perpendicular to the upright portion 60a and connected to the inner peripheral surface of the band 46 are preferably configured. In the above embodiment, the main connecting portion 60 and the auxiliary connecting portion 62 constitute the connecting portion, but the main connecting portion 60 alone may constitute the connecting portion.

  Furthermore, it is preferable that a deforming projection 64 having a curved or inclined peripheral side surface is provided adjacent to the main connecting portion 60 on the inner peripheral surface of the band 46. When the cap 16 is opened, the deforming projection 64 contacts the outer peripheral portion of the pouring piece 14 (particularly, the outer peripheral portion of the stopper 24, the outer claw portions 41, 43, etc.) and directs the band 46 outward. It exerts the action of deforming. The deformation projection 64 is provided at a position where at least a part of the deformation projection 64 overlaps the main coupling portion 60 in the circumferential position. For example, in the embodiment shown in FIGS. 2 and 3, the partial cylindrical deformation protrusion 64 having a circumferential side surface curved in an arc shape has a width just below the horizontal portion 60 b of the main coupling portion 60. It is provided integrally with the horizontal portion 60 b at a position where the center line in the direction (circumferential direction of the band 46) and the center line in the width direction of the main coupling portion 60 coincide.

Next, a method for using such a plug unit 10 will be described.
The pouring piece 14 has its straw portion 20 inserted into the inside of the packaging container 12 through the spout of the packaging container 12 and the mounting portion 36 is fitted to the spout in a packaging container on the ear 38 of the mounting portion 36. The packaging material around the 12 spouts is attached to the spout of the packaging container 12. When the cap 16 is removed from the dispensing piece 14, the contents of the packaging container 12 flow into the dispensing piece 14 through the suction port 26 and the elongated hole 28 formed in the straw portion 20 of the dispensing piece 14. , It can be discharged from the mouth 18 to the outside. Further, the male screw 22 formed on the outer peripheral surface of the mouth portion 18 of the pouring piece 14 and the female screw 48 formed on the inner peripheral surface of the cap main body 44 of the closing cap 16 are screwed together to thereby form the mouth portion 18 of the pouring piece 14. If the closure cap 16 is fitted to the mouthpiece 18, the mouth portion 18 of the dispensing piece 14 can be closed.

  When the closing cap 16 is screwed into the dispensing piece 14 for the first time and the mouth 18 of the dispensing piece 14 is closed, the closing cap 16 is formed on the inner peripheral surface of the band 46 as shown in FIG. In the closing direction (opposite to the arrow in FIG. 4) until the inner claw portions 56, 58 are in contact with the outer claw portions 41, 43 of the extraction piece 14 and get over them, respectively. Rotated. The tips of the outer claw portions 41 and 43 of the pouring piece 14 are bent in the closing direction (the direction opposite to the arrow in FIG. 4), while the tips of the inner claw portions of the band 46 of the closing cap 16 are opened. Since it is bent in the direction (the direction of the arrow in FIG. 4), the cap 46 is rotated in the closing direction (the direction opposite to the arrow in FIG. 4) with respect to the dispensing piece 14, and the band 46 of the plug cap 16. Even if the inner claw portions 56, 58 of this contact the outer claw portions 41, 43 of the extraction piece 14, they can be easily overcome. When the closing cap 16 is rotated with respect to the pouring piece 14 to this position, the closing end of the closing cap 16 is brought into close contact with the opening end of the mouth 18 of the pouring piece 14 and the mouth 18 of the pouring piece 14 is moved. Can be plugged.

  When opening the plug, the cap 16 is rotated in the opening direction with respect to the dispensing piece 14. However, in an unopened state, the tips of the inner claw portions 56 and 58 of the band 46 of the closure cap 16 bent toward the opening direction and the outer claw portion 41 of the pouring piece 14 bent toward the closing direction. , 43 are engaged like ratchet teeth, and cannot be easily overcome. From this state, if the cap 16 is further rotated in the opening direction with respect to the dispensing piece 14, the portion of the band 46 located on the rear side in the opening direction with respect to the dividing portion 52 is prevented from rotating. On the other hand, the portion of the band 46 located on the front side in the opening direction with respect to the dividing portion 52 tends to rotate together with the cap body 44 connected by the main coupling portion 60. As a result, a tensile force acts on the connection piece 54 provided in the dividing portion 52 and breaks. At the same time, the auxiliary connecting part 62 is also broken. Further, immediately before the connection piece 54 is broken, the portion of the band 46 located on the rear side in the opening direction with respect to the dividing portion 52 is connected to the portion of the band 46 located on the front side in the opening direction with respect to the dividing portion 52. Since a tangential tensile force is applied through the piece 54, the portion of the band 46 on the front side in the opening direction is rotated and deformed around the main connecting portion 60. When the closing cap 16 is further rotated in the opening direction after the connecting piece 54 and the auxiliary connecting portion 62 are broken, the inclined or curved peripheral side surface of the deformation projection 64 provided below the horizontal portion 60b of the main connecting portion 60. Comes into contact with the corners of the outer edge of the stopper 24 of the extraction piece 14 and the outer claw portions 41 and 43, and the portion of the band 46 on the front side in the opening direction is turned and deformed around the main connecting portion 60.

  Since the band 46 is divided in this way, it can be recognized that the capping cap 16 has been opened once. Therefore, if the band 46 is not divided, it is in an unopened state, and if the band 46 is divided, it is opened. It is possible to determine that the state has been completed, and to perform a falsification preventing function. Further, the deformation of the band portions 46a and 46b due to the breaking of the connection piece 54 of the band 46 serves to facilitate the recognition of whether or not the band 46 is broken.

  By the way, the deformation of the band portions 46a and 46b is not necessarily large in any case, and it is desirable that the deformation amount can be adjusted depending on the application. In particular, when the packaging container 12 is repeatedly used and opened and closed by the closing cap 16, it is preferable to reduce the deformation amount of the band 46 so as not to hinder the handling of the closing cap 16.

  The present applicant controls the amount of deformation of the band portions 46a and 46b based on the circumferential width of the main connecting portion 60 and the relative positional relationship between the center line of the deformation projection 64 and the center line of the main connecting portion 60. It has been found that it can be used as a deformation amount adjusting means. That is, when the applicant increases the circumferential width of the main connecting portion 60, the amount of deformation of the band portions 46a and 46b when the connecting piece 54 is cut decreases, and the width of the main connecting portion 60 in the circumferential direction is reduced. If it is made smaller, the deformation amount of the band portions 46a and 46b after the connecting piece 54 is broken is found to increase, and the center line of the deformation projection 64 is set to the center line of the circumferential width of the main connecting portion 60. It has been found that the amount of deformation of the band portions 46a and 46b after the connecting piece 54 is broken is greater when the offset is arranged than when the two center lines are aligned.

  Hereinafter, with reference to FIGS. 5 to 10, the band portion 46 a is changed by changing the circumferential width of the main connecting portion 60 and changing the relative positional relationship between the center line of the deformation projection 64 and the center line of the main connecting portion 60. , 46b will be described.

  The state in which the inner claw portions 56 and 58 of the band 46 of the capping cap 16 shown in FIG. 7 are engaged with the outer claw portions 41 and 43 of the dispensing piece 14 (for the sake of simplicity, the dispensing piece 14 When the cap 16 is further rotated in the direction of opening (in the direction of the arrow in FIG. 7), as described above, after the direction of opening of the plug 52, the claw portions 41, 43 are omitted. The portion of the band 46 positioned on the side applies a tensile force through the connecting piece 54 to the portion of the band 46 positioned on the front side in the opening direction with respect to the dividing portion 52. On the other hand, since the band portions 46 a and 46 b are arranged on the circumference, the portion of the band 46 on the rear side in the opening direction acts on the portion of the band 46 on the front side in the opening direction adjacent to the dividing portion 52. The tensile force includes a radially inward component. Therefore, when the tensile force as described above acts on the end of the band portion 46a or 46b located on the front side in the opening direction with respect to the dividing portion 52, the connection piece 54 is shown in FIG. As shown in the figure, with respect to the center line 66 of the circumferential width of the main connecting portion 60, the rear portion of the band portion 46a or 46b pivots and deforms inward to open the band portion 46a or 46b. The front part turns and deforms outward. Therefore, as shown in the left part of FIG. 5, by increasing the circumferential width of the main connecting portion 60 (for example, by setting the angular width to 15 °), the main connecting portion 54 is broken after the connection piece 54 is broken. The force with which the portion 60 restores the band portions 46a and 46b to the original state increases, and the deformation amount of the band portions 46a and 46b decreases, whereas the main connection as shown in the right portion of FIG. By reducing the circumferential width of the portion 60 (for example, by setting the angular width to 10 °), the main connecting portion 60 can return the band portions 46a and 46b to the original state after the connection piece 54 is broken. As a result, the band portions 46a and 46b become larger in deformation. The present invention takes advantage of this fact, and uses the circumferential width of the main connecting portion 60 as the deformation amount adjusting means, so that the deformation amount of the band 46 of the closure cap 16 can be adjusted according to the application.

  It has also been found that the relative positional relationship of the center line 68 of the deformation protrusion 64 with respect to the center line 66 of the circumferential width of the main connecting portion 60 also affects the amount of deformation of the band portion. For example, the relative position of the center line 68 of the deformation protrusion with respect to the center line 66 of the main connecting portion 60 is the center line 68 of the deformation protrusion 64 'having an arcuate side surface as shown in the left part of FIG. May be changed by being offset with respect to the center line 66 of the main connecting portion 60, and the deformation protrusion 64 ″ is arranged at the center line of the main connecting portion 60 as shown in the right part of FIG. 6. It may be changed by forming it to be asymmetric with respect to 66.

  As described above, the relative positional relationship of the center line 66 of the deformation projections 64 ′ and 64 ″ with respect to the center line 66 of the main connecting portion 60 affects the deformation amount of the band portions 46 a and 46 b as described above. 46a and 46b originally try to deform around the center line 66 of the main connecting portion 60, but the center line 68 of the thick and rigid deforming projections 64 'and 64 "is front side or rear side in the opening direction. This is presumed to be because the center of deformation becomes the center line 68 of the deformation projections 64 ′ and 64 ″. For example, as shown in FIG. On the other hand, when the deformation projection 64 ′ is provided such that the center line 68 of the deformation projection 64 ′ is offset to the front side in the opening direction (the direction of the arrow in the figure), the deformation center is the main connection. Front direction of opening with respect to center line 66 of portion 60 Since the center line 68 of the deformation projection 64 ′ is located on the side of the main connection portion 60 closer to the dividing portion 52, the deformation is more easily deformed inward, and the center line 68 of the deformation projection 64 is the main connection. The amount of deformation of the band portions 46a and 46b becomes larger than when the center line 66 coincides with the center line 66 of the portion 60 (in the case of the deformation projection 46), as shown in FIG. When the deformation projection 64 ′ is provided such that the center line 68 of the deformation projection 64 ′ is offset to the rear side of the opening direction (the direction of the arrow in the figure) with respect to the center line 66, Since the center is the center line 68 of the deformation projection 64 ′ located on the rear side in the opening direction with respect to the center line 66 of the main connecting portion 60, the side farther from the dividing portion 52 of the main connecting portion 60 is the outer side. The center line 68 of the deformation projection 64 is the main connecting portion 60. The amount of deformation of the band portions 46a and 46b becomes larger than when the center line 66 coincides (in the case of the deformation projection 64), and therefore the amount of deformation of the band portions 46a and 46b after the cut piece 54 is broken. When it is desired to reduce the size, the deformation protrusion 64 is provided so that the center line 68 of the deformation protrusion 64 coincides with the center line 66 of the main connecting portion 60, and the band portions 46a and 46b are deformed after the cut piece 54 is broken. When it is desired to increase the amount, deformation is performed so that the center line 68 of the deformation projection 64 ′ or 64 ″ is offset at the front side or the rear side in the opening direction with respect to the center line 66 of the main connecting portion 60. Protrusion 64 'or 64 "may be provided.

  As described above, according to the present invention, the deformation amount adjusting means can adjust the deformation amount of the band 46 of the closure cap 16 according to the application, and the deformation amount of the band 46 can be reduced in the application where the closure cap 16 is repeatedly used. While the band 46 can be kept out of the way during use, the user can confirm that the cap 46 has been opened by increasing the amount of deformation of the band 46 in applications where the cap 16 is disposable. It can be easily recognized.
