It is characterized by that.

Claim 5
“In the description of any one of the first to fourth aspects, the connecting piece is provided with a heel that deforms in a direction away from the main body and the cap, and a state in which the ridge of the sleigh deformation is extended. It is the structure which adheres to the said main body and the said cap. "
It is characterized by that.

  In the description of claims 1 and 2, since the cap is connected to the main body via a connecting piece, the connecting piece is cut off from the main body or the cap, or the main body or cap of the connecting piece is attached to the cap. As long as the fixed part is not removed, it cannot be opened and remains sealed.

  In other words, whether or not the connecting piece is broken off from the main body or the cap, or whether the portion fixed to the main body or the cap is removed or not, can be visually confirmed when it is tampered with at the distribution stage.

  Therefore, by placing the finger on the tab provided on the cap and pushing it up in the direction away from the main body, the connecting piece is cut off from the main body or the cap, or the main body or Since the portion fixed to the cap is removed, the sealing of the main body is released, and the cap can be opened (opened).

  In this unsealing, the part cut off from the main body or the cap remains fixed to the cap or the main body, while the connecting piece that is not fixed to the main body or the cap remains fixed to the cap or the main body. , Since it does not fall off from the main body and the cap, they can be prevented from becoming trash, and there is no risk of swallowing by infants. In addition, since the sealing is released by one operation of raising the cap, it is possible to quickly open and take out the contents.

  According to the third aspect of the present invention, a force for cutting off the connecting piece by a force for pushing up the cap, or a force for removing the connecting piece from fixing to the main body or the cap, the connecting piece is close to a tab on the cap. Since it can be enlarged by the principle of the lever as compared with the case where it is provided at the site, opening by pushing up the cap can be facilitated.

  According to a fourth aspect of the present invention, when the cap is pushed up by placing a finger on the tab, the cap can be prevented from being twisted and deformed so as to be greatly inclined to the left and right by the left and right connecting pieces. Since the force to cut or remove the connecting piece can be concentrated on the connecting piece, the opening by pushing up the cap can be further facilitated.

  In particular, according to the fifth aspect of the present invention, the torn or detached connecting piece returns to the state of the original warped deformed ridge by its elasticity and protrudes away from the main body or the cap. Thus, it is possible to more easily and reliably confirm whether or not the package has been opened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings of FIGS.

  Among these drawings, FIGS. 1 to 7 show the lid device according to the first embodiment.

  The lid device is made of a synthetic resin, and includes a main body 1 and a cap 2, and both are integrally connected via a hinge 3 that is bendable and thin.

  The main body 1 includes an outer cylinder 6 that fits into the mouth 5 of the container 4 from the outside, an inner cylinder 7 that fits into the mouth 5 of the container 4 from the inside, and a spout 8 that is continuous with the upper end of the inner cylinder 7. And a closing plate 9 for sealing the extraction passage at the boundary between the inner cylinder 7 and the outlet 8.

  An annular engagement groove 5a is formed on the outer surface of the mouth portion 5 of the container 4, while an annular protrusion 6a that fits the annular engagement groove 5a is formed on the outer cylinder 6 of the main body 1. ing.

  The upper ends of the outer cylinder 6 and the inner cylinder 7 are integrally continuous via a step portion 10, and an upward ring portion 11 surrounding the spout 8 is formed in the step portion 10.

  As shown in FIG. 3, the spout 8 is stepped so that a half portion near the hinge 3 is lowered. The closing plate 9 is formed with a loop-like score (thin wall portion) 12, and a pull ring (pull tab) 13 is integrally provided at the end of the portion surrounded by the score 12. Needless to say, the content (liquid) can be poured out by pulling the pre-ring 13 and tearing the portion of the score 12.

  The cap 2 is provided with a cylindrical portion and a top plate so as to overlap the stepped portion 10 of the main body 2 in a closed state, and the top plate is provided with a middle foot 14 that fits into the spout 8 from the inside. .

  Further, a tab 15 for pushing up the cap 2 away from the main body 1 is integrally formed outwardly at a free end portion of the cap 2 located on the opposite side of the hinge 3 when viewed from the axial direction. It is protruding. On the lower surface of the tab 15, a rib for improving finger catching is formed.

  The outer peripheral portion of the cap 2 is integrated so that a connecting piece 16 having a relatively narrow width W of about 2/10 to 1/6 of the diameter of the main body 1 extends downward toward the main body 1. Is provided.

  As shown in FIG. 2, a pair of connecting pieces 16 are provided on both the left and right sides of a line 17 connecting the hinge 3 and the tab 15 when viewed from the axial direction of the main body 1 and the cap 2, and a tip portion 16a thereof is provided. As shown in FIG. 4, it is fixed to the outer peripheral surface of the outer cylinder 6 in the main body 1 by welding by heating or by bonding with an adhesive. In addition, the fixed part by the said welding or adhesion | attachment is shown with the code | symbol 18. In FIG.

  In addition to this, the pair of left and right connecting pieces 16 are arranged between the hinge 3 and the tab 15 in FIGS. 1 and 2 when the main body 4 and the cap 2 are viewed from a direction perpendicular to the axis thereof. As shown by a two-dot chain line, it may be provided at a location close to the tab 15 or just at an intermediate location, but in reality, as shown by a solid line in FIGS. The distance L1 from 3 to the connecting piece 16 is shorter than the distance L2 from the tab 15 to the connecting piece 16, that is, when viewed from the axial direction of the main body 1 and the cap 2, the distance from the tab 15 is greater than that of the tab 15. It is preferable to provide in the part near the hinge 3 side.

  Then, as shown in FIG. 4, the pair of left and right connecting pieces 16 are provided with a fragile portion 19 such as a V-groove or a perforation at the base portion of the cap 2 so that the tab 15 of the cap 2 is attached. When pushed upward, the distal end portion 16a of the connecting piece 16 remains fixed to the main body 1 and is cut off at the weakened portion 19 portion.

  In this configuration, since the cap 2 is connected to the main body 1 via the connecting piece 16, the cap 16 cannot be opened unless the connecting piece 16 is broken at the weakened portion 19 and sealed. ing. In other words, whether or not the cap 2 has been tampered with at the distribution stage can be visually confirmed by whether or not the connecting piece 16 is broken at the weakened portion 19.

  Therefore, by placing the finger on the tab 15 provided on the cap 2 and pushing it up in the direction away from the main body 1, the connecting piece 16 is connected to the weakened portion 19 provided at the base portion thereof. Since the cap 2 is torn off, the cap 2 is released from sealing with respect to the main body 1 and can be opened (opened) as shown in FIGS.

  In this unsealing, the broken connecting piece 16 from the cap 2 remains fixed to the main body 1 at the tip portion 16a and does not fall off from the main body 1. Therefore, the broken connecting piece 16 However, it can avoid becoming garbage and eliminate the possibility of being swallowed by infants.

  In this case, the connecting piece 16 is provided on both the left and right sides when viewed from the axial direction, so that when the cap 2 is opened, when the cap 2 is pushed up, the cap 2 is inclined greatly to the left and right. Since the twisted deformation can be prevented by the pair of left and right connecting pieces 16, it is possible to concentrate the force of breaking the connecting pieces 16.

  Further, the connecting piece 16 is provided in a portion between the hinge 3 and the tab 15 closer to the hinge 3 side than the tab 15, so that the connecting piece 16 is applied by a force for pushing up the cap 2. Since the force that breaks 16 can be made larger by the lever principle than when the connecting piece 16 is provided in the portion of the cap 2 close to the tab 15, the opening is facilitated.

  In the first embodiment described above, instead of providing the connecting piece 16 integrally with the cap 2, the connecting piece 16 is provided integrally with the main body 1, and the tip portion 16 a thereof is connected to the cap 2. It can be configured to be fixed by welding or the like.

  In this case, that is, when the connecting piece 16 is provided integrally with the main body 1, it is possible to apply that the pair of connecting pieces 16 are provided on the left and right sides, and that the connecting piece 16 is provided near the hinge 3 side. Of course.

  Further, in the first embodiment, when the connecting piece 16 is provided integrally with the cap 2 or the main body 1, the connecting piece 16 is formed when the cap 2 or the main body 1 is injection-molded. As shown by a two-dot chain line in FIG. 5, it is formed into a shape having a warp deformed in a direction away from the cap 2 or the main body 1, and the warped deformed warp in the connecting piece 16 is elastically deformed. Then, the tip portion 16 is fixed to the main body 1 or the cap 2 by welding or the like.

  With this configuration, when the connecting piece 16 is broken at the weakened portion 19, as shown by a two-dot chain line in FIG. Since it protrudes away from the said main body 1 by returning to the state of this, confirmation of the presence or absence of opening can be performed more easily and reliably by this.

  In the present embodiment, one connecting piece 16 is provided on each of the left and right sides of the line connecting the hinge 3 and the tab 15, but the connecting piece 16 is formed in a thin string shape (or a bridge shape) and slightly in the circumferential direction. It is also possible to dispose a set of string-like connecting pieces on the left and right sides or one side of the line connecting the hinge 3 and the tab 15 with a plurality of connecting pieces 16 arranged with a gap therebetween as a set. In this case, the connecting piece 16 is string-like and easily cut off, and the connecting piece 16 is cut off in order from the one close to the tab 15 as the cap 2 is raised, so that the raising operation of the cap 2 is performed with a light force. It becomes possible.

  Next, FIG.8 and FIG.9 has shown the modification in the said 1st Embodiment.

  In this modification, instead of fixing the connecting piece 16 provided integrally with the cap 2 to the main body 1 by welding or adhesion, the connecting piece 16 having a narrow width W provided integrally with the cap 2 is used. The flange 16b is formed as a flange 16b, and the flange 16b is fixed to the main body 1 by being inserted into and engaged with the hole 20 provided in the main body 1 so as not to be pulled out. In other respects, the configuration is the same as that of the first embodiment.

  In the case of this configuration, by providing a weakened portion 19 with a V-groove or a perforation at the base of the connecting piece 16, the weakened portion 19 remains fixed to the main body 1 while the distal end portion 16 a is fixed to the main body 1. The portion 19 is configured to be broken.

  That is, the cap 2 can be opened when the connecting piece 16 is broken from the cap 2 by being pushed up, and the broken connecting piece 16 remains in the hole 20 of the main body 1. , It will not fall off the main body 1.

  In the second embodiment, the connecting piece 16 'is made of a synthetic resin film which is separated from the cap 2 or the main body 1 without integrating the connecting piece of the narrow width W with the cap 2 or the main body 1. Thus, both ends of the connecting piece 16 'are fixed to both the main body 1 and the cap 2 by welding or adhesion.

  In addition, the fixed part with respect to the said main body 1 of the said connection piece 16 'is shown with the code | symbol 18', and the fixed part with respect to the said cap 2 is shown with the code | symbol 18 ''.

  In the second embodiment, as shown in FIGS. 10 and 11, a V-groove or a half of the connecting piece 16 is provided between the fixing portion 18 'at one end and the fixing portion 18' 'at the other end. By providing the fragile portion 19 ′ by a perforation or the like, when the tab 15 of the cap 2 is pushed upward, both ends of the connecting piece 16 ′ remain fixed to the main body 1 and the cap 2. The connecting piece 16 ′ is cut off at the fragile portion 19 in the middle thereof so that the cap 2 can be opened.

  In the case of this configuration, the connecting piece 16 ′ does not fall off from the main body 1 and the cap 2 because both ends thereof remain fixed to the main body 1 and the cap 2.

  Further, in the modification of the second embodiment, instead of configuring the connecting piece 16 'to be broken in the middle thereof, a fixing portion 18' at one end of the connecting piece 16 ', and the like. When the tab 15 of the cap 2 is pushed upward by providing a difference in fixing strength with the fixing portion 18 ″ at the end, as shown in FIG. 12, both the fixing portions 18 ′ and 18 ″. Any one of the two can be configured to be removed earlier than the other so that the cap 2 can be opened.

  According to the configurations of the second embodiment and its modifications, it is possible to obtain the same effects as those of the first embodiment, as well as those of the second embodiment and its modifications. In connection with the configuration, as shown in FIG. 10 by a two-dot chain line, the connecting piece 16 ′ is preliminarily warped and deformed, so that the broken connecting piece 16 ′ can be separated into two pieces in FIG. As shown by the dotted line, the connecting piece 16 ′ which protrudes outwardly or is not fixed to the main body 1 or the cap 2 is directed outward as shown by the two-dot chain line in FIG. 12. In addition to being configured to protrude, it is possible to apply a configuration in which a pair of connecting pieces 16 'are provided on the left and right sides, and a structure in which the connecting pieces 16' are provided on a portion close to the hinge 3 side.

  The present invention is useful when embodied in a hinge cap type lid device. Therefore, it can be used industrially.
