Description

  The present invention relates to a hinge cap used by being attached to the mouth of a container, and more particularly to a hinge cap with a tamper-proof band.

  A conventional hinge cap is provided with a tamper-proof band to prevent unauthorized opening due to mischief or the like. In this hinge cap, a tamper-proof band is integrally formed by connecting with the lower lid and the connection portion, covering the opening claw portion and the periphery of the contact surface portion of the upper lid and the lower lid, and the outer peripheral convex portion of the upper lid and the tamper-proofing The concave portion of the band is fitted, pulled by the pulling portion, and the upper lid cannot be opened unless the connecting portion is cut and removed (see, for example, Patent Document 1).

Japanese Utility Model Publication No.2-129057

The conventional example has the following problems.
1: There is a possibility that a finger is put in the gap between the tamper-proofing band and the upper lid and spreads, the engagement is released without separating the band, and the lid is opened without leaving a trace. Therefore, if the lid is closed after being tampered with, the band will return to its original state, and it may not be known that the tamper has been tampered with.
2: When the molten resin is injected into the mold at the cap molding stage, cooled, and taken out from the mold, the band of the cap falls inward due to thermal contraction. When the upper lid is closed and set in this state, both ends of the band may be sandwiched between the upper lid and the lower lid.
3: The conventional cap has to be pulled up by holding the handle portion of the falsification preventing band and cutting and removing the connecting portion (bridge), and then push it upward with a finger on the opening claw portion. Thus, since the first action for pulling the handle part of the band and the second action for opening the upper lid are necessary, it is troublesome and cannot be quickly opened.

  In view of the above circumstances, an object of the present invention is to prevent unauthorized opening and prevent tampering of an anti-tamper band. Another purpose is to make opening easier.

  The present invention provides a cap body having a contact surface with a lower end portion of an upper lid mounted on a container, an upper lid hinged to the cap body, and spaced apart along an outer peripheral edge of the contact surface. A hinge cap comprising: a tamper-proof band coupled to the cap body via a tearable connecting portion; and a locking means between the tamper-proof band and the upper lid; It is comprised from the latching nail | claw provided in the latching | locking part of the prevention band, and the narrow-width vertical recessed part provided in the engaging part of the knob | pick part of the said upper cover, It is characterized by the above-mentioned.

  According to the present invention, a cap main body having a contact surface with the lower end of the upper lid mounted on the container, an upper lid hinged to the cap main body, and an outer peripheral edge of the contact surface are spaced apart from each other. A hinge cap provided with a tamper-proof band connected to the cap body via a tearable connecting portion; and a locking means between the tamper-proof band and the upper lid; The locking claw provided in the locking part of the tamper-proof band and a narrow vertical recess provided in the engaging part of the knob part of the upper lid, and both ends of the tamper-proof band are in contact with the abutment It is characterized in that it is spaced from the outer peripheral edge of the surface.

  The present invention provides a cap body having a contact surface with a lower end portion of an upper lid mounted on a container, an upper lid hinged to the cap body, and spaced apart along an outer peripheral edge of the contact surface. A hinge cap comprising: a tamper-proof band coupled to the cap body via a tearable connecting portion; and a locking means between the tamper-proof band and the upper lid; A locking claw provided in the locking portion of the prevention band, and a narrow vertical recess provided in the engagement portion of the knob portion of the upper lid, and both end portions of the tamper-proof band are the contact surface It is characterized in that a finger recess is formed by lacking a portion corresponding to the knob portion of the upper lid of the contact surface.

  The lower end surface of the tamper-proof band of the present invention is located on the same plane as the contact surface and can be opened with one action.

  The cap main body of the present invention is characterized in that a longitudinal direction weakening line and a circumferential direction weakening line for separation are provided.

  In this invention, the locking means is composed of a locking claw provided in the locking portion of the tamper-proof band and a narrow vertical recess provided in the engaging portion of the knob of the upper lid. If you try to pry the band with your finger, the connection will break. Therefore, it can be seen that the tampering has been surely made.

  In this invention, since both ends of the tamper-proof band are spaced from the outer peripheral edge of the contact surface, the both-ends of the band are not sandwiched when the upper lid is set after the hinge cap is formed. .

  According to the present invention, since the concave portion for the finger is formed by lacking the portion of the abutment surface corresponding to the knob portion of the upper lid, the protruding amount of the band can be minimized and the finger can be reliably applied.

  Since the lower end surface of the tamper-proof band of the present invention is located on the same plane as the contact surface, if the finger is applied to the lower end surface of the knob, the finger is also applied to the lower end surface at the same time. Therefore, when the upper lid is pushed open with the finger, the connecting portion of the band is cut at the same time, so that the lid can be opened and opened with a so-called one action.

A first embodiment of the present invention will be described with reference to FIGS.
The hinge cap HC is integrally formed of a synthetic resin and includes a cap body 1, an upper lid 30, and a hinge H that connects the cap body 1 and the upper lid 30.

  The cap body 1 includes a fitting cylinder 2 and a seal cylinder 3 continuous with the fitting cylinder 2. The fitting cylinder 2 has an outer cylinder 5 and an inner cylinder 6 with an annular protrusion 12 that sandwich the mouth 4 of the container, a note cylinder 9 that is closed by a blocking wall 7, and an outside of the note cylinder 9. The locking ridge 10 is provided.

  The blocking wall 7 is provided with an annular fissure 14, and a pull ring 15 is erected inside the fissure 14. The outer diameter of the seal cylinder 3 is formed larger than the outer diameter of the outer cylinder 5. Therefore, both the cylinders 3 and 5 are stepped and continuous, and the outer peripheral surface 5 a of the outer cylinder 5 is continuous with the outer peripheral surface 3 a of the seal cylinder 3 via the contact surface 16. Although not shown, the seal cylinder 3 is provided with a longitudinal weakening line and a circumferential weakening line for separation.

  The contact surface 16 is a surface with which the lower end surface 30a of the upper lid 30 comes into contact when the lid is closed. A finger recess 18 is provided in a portion of the seal cylinder 3 corresponding to the knob 31 of the upper lid 30.

  A tamper-proof band 20 is provided on the outer side of the outer cylinder 5, and the band 20 is disposed along the outer peripheral edge of the contact surface 16. The band 20 is connected to the upper end edge of the seal cylinder 3 via the connection portion B, and the lower end surface 20 a thereof is located on the same plane as the contact surface 16. In addition, the said connection part B is a part torn when the said band 20 is pulled, for example, the bridge is used as this connection part.

  The band 20 has an arc shape, and the center angle θ is 240 degrees, and the center angle θ is preferably 180 degrees or more. Both ends 20b of the band 20 are expanded in diameter and face the fitting cylinder 2 with a pinching prevention interval w.

  On the inner peripheral surface of the locking portion 20c of the band 20, a downward locking claw 20d is projected. The locking claw 20d has a narrow width, for example, 4.9 mm. A connection portion B is not provided at a portion corresponding to the locking portion 20c of the band 20, and a space portion 26 is formed between the locking portion 20c and the abutting surface 16. The portion 26 communicates with the finger recess 18.

  Inner and outer seal rings 33 and 34 that abut against the tip of the injection cylinder 9 when the lid is closed project from the top surface 32 of the upper lid 30. 10 is provided.

  The knob 31 is provided on the opposite side of the outer periphery of the skirt 35 from the hinge H, and faces the locking portion 20 when the lid is closed. The knob 31 is a protrusion having a small arc-shaped outer peripheral surface, and a narrow vertical recess 38 is integrally formed at the center engaging portion. As shown in FIG. 4, the concave portion 38 has a concave shape, and is formed to have a size, for example, 5 mm, into which the locking claw 20d can be inserted and a finger cannot enter. The bottom surface 38 a of the groove 38 is located on the same plane as the central top line 24 of the tamper-proof band 20.

  Next, the operation of this embodiment will be described. After forming the hinge cap HC in the open state, the upper cover 30 is set by rotating in the closing direction. At this time, the locking claw 20 enters and locks into the narrow vertical recess 38, and both end portions 20b of the band 20 are separated from the skirt 35, so that they are not caught.

  A hinge cap HC with a falsification preventing band 20 is plugged into the mouth portion 4 of the container filled with liquid or the like, and the state shown in FIG. 3 is obtained.

In the case of mischief opening When trying to open tamperingly, the band 20 is pry open with a finger to release the engagement between the locking claw 20d and the narrow vertical recess 38. However, since the width of the groove 38 is narrow, the connection portion B is torn off if the finger does not enter and it is forcibly opened. Therefore, it is possible to know unauthorized opening.

In case of normal opening When the lid is used for the first time, a finger is put on the lower end surface of the knob 31. Then, the finger also comes into contact with the lower end surface 20a of the band 20 at the same time. At this time, since the finger recess 18 is provided in the seal cylinder 3, the finger can be surely brought into contact without the knob 31 and the band 20 protruding so far outward.

  When the finger is pushed upward in this state, the connection portion B is cut, and the upper lid 30 is separated from the contact surface 16 and is in an open state. That is, since the lid can be opened with only one action, the opening operation is facilitated.

Next, when the pull ring 15 is pulled with a finger, the fissure 14 is cut, the blocking wall 7 is removed, and an open state is obtained.
When the container is held and tilted, the contents flow out of the container through the injection tube 9. After the desired amount has been poured out, the container is returned to its original position, and then the top surface 32 of the upper lid 30 is pushed in the closing direction with a finger to close the lid.
Further, after the contents have been used up, the cap body 1 and the container are separated by tearing the longitudinal and circumferential weakening lines provided on the outer cylinder 5 for separation and collection.

A second embodiment of the present invention will be described with reference to FIG. 5. The same reference numerals as those in FIGS. 1 to 4 have the same names and functions.
The main difference between this embodiment and the above embodiment is that no seal cylinder is provided. In this embodiment, the upper end surface 40 of the outer cylinder 5 is used as the contact surface instead of the upper surface of the stepped portion of the seal cylinder and the fitting cylinder, and the connecting portion of the tamper-proof ring 20 is the outer cylinder. 5 is fixed to the upper end.

It is a figure which shows 1st Embodiment of this invention, and is a top view in an open cover state. It is a front view. It is a longitudinal cross-sectional view at the time of closing. It is an enlarged front view at the time of a lid closing. It is a figure which shows 2nd Embodiment of this invention, and is an expanded longitudinal cross-sectional view in a closed state.
