Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hinge cap in which tamper evidence (hereinafter referred to as TE property) is added to an upper lid.
[0002]
[Prior art]
In the case of a cap having a structure in which a cap body is fitted and attached to the container mouth by a stopper and an upper lid hinged to the cap body, and the spout is opened by a pull ring on the top wall of the cap body. Even if the upper lid is opened due to mischief, etc., the seal is maintained unless the score breaks, but if the upper lid can be freely opened and closed during the distribution process, the upper lid is closed even if the score is broken due to mischief Since the state cannot be determined from the outside, it is desirable that the upper lid also has TE properties. As a means for imparting such TE properties, it is generally performed to wrap the container mouth including the upper lid with a shrink film. In this case, in the container sealing process, in addition to the capping process, the shrink process is further performed. There is a problem that the number of processes increases.
[0003]
As a conventional technique for solving this problem, for example, on the outer periphery of the cap main body, a strip that is opposed to the cap main body with a space therebetween and both ends are connected to the cap main body via a weakening line is integrally formed. At the same time, the upper lid is integrally formed with a latching claw that is inserted between the strip and the cap body when the cap body is crowned, and the strip and the latching claw are locked in the closed state. In addition, there has been proposed one in which the weakening line on one end side of the strip is broken when the upper lid is opened so that the upper lid can be easily known (for example, patent document) 1-3). On the other hand, as a disadvantage of the hinge cap, when closing the hinge cap after pouring out the content liquid, the hinge lid edge vigorously hits the opening edge due to the spring force of the hinge, so the residual liquid of the content liquid adhering to it It may scatter around and stain your clothes.

[Problems to be solved by the invention]
The hinge cap having the above-mentioned TE property that has been proposed in the related art is as long as the locking projection provided on the upper lid engages with the jaw portion of the strip provided on the cap body when the upper lid is opened, and the strip is not broken. Since the upper lid cannot be opened, it has tamper evidence in that it can be determined whether the upper lid has been opened or closed by observing the presence or absence of a strip. However, since the front end portion of the finger cover piece of the upper lid and the engaging portion of the strip and the locking claw are exposed or opened to the outside in the closed state, the engaging portion may be tampered with by a tool or the like from the outside. In order to prevent the upper lid from being opened due to the mischief, it is necessary to increase the engagement protrusion between the upper lid and the strip so that the upper lid and the strip are firmly locked. Therefore, when the upper lid is closed in the cap manufacturing process, the engagement protrusion will force the jaw part over, and there is a possibility that a large tension acts on the strip and the weakening line of the strip may be broken unexpectedly. There is a problem that is disadvantageous in improving the yield rate. Moreover, since the thing shown in patent document 3 must form a sealing member so that it may reach to the lower end position of a cap main body, there is a problem that the amount of resin which forms a cap increases so much and cost becomes high. Further, the conventional hinge cap has a problem that when the hinge cap is closed after the content liquid is poured out as described above, the residual liquid of the content liquid adhering thereto scatters around and stains the clothes. .
[0006]
The present invention is to solve the above-mentioned problems of the prior art, and in a cap having a hinge top cover, the uncovered state of the bottom surface or the front edge of the finger hook piece of the top cover, and the relationship between the top cover and the tamper evidence band. The joint cannot be touched directly, and the upper lid can be reliably prevented from being opened by mischief without increasing the protrusion of the upper lid and the engagement band, the yield rate of productivity can be improved, and the upper lid can be opened. Provides an unopened proof that can be easily discriminated whether or not it has been applied, and provides a hinge cap with TE added to the upper lid that prevents splashing of the remaining liquid adhering to the outer peripheral surface of the cap body when the lid is closed The purpose is to do.
[0007]
[Means for Solving the Problems]
The hinge cap of the present invention that solves the above-mentioned problems is formed on the opposite side of the upper lid from the hinge coupling portion in a hinge cap comprising a cap body mounted on the container mouth and an upper lid hinged to the cap body. A tongue piece projecting downward is provided on the lower surface of the finger-hanging piece, and at least one end portion of the cap body has a skirt wall so that a gap can be inserted between the skirt wall and the outer peripheral surface of the skirt wall. A tamper evident band connected via a weakening line is provided, and the tamper evidence band has a finger hanger engagement baffle protrusion on the upper portion that hinders the finger hanger from being hooked on the finger hanger. It is a feature.
[0008]
The tamper-evidence band has a belt-like tongue piece engagement locking wall portion for forming a gap in which the tongue piece is engaged and locked with the outer peripheral surface of the skirt wall, and the upper surface has the same shape as the lower surface of the finger hanging piece. The finger-hanging piece seat portion formed on the outer periphery of the finger-hanging piece seat portion and standing in a closed state surrounding the outer surface of the finger-hanging piece and preventing the finger from directly engaging the finger-hanging piece in an unopened state And a finger-hanging piece engaging baffle projection. Then, by providing the finger-hanging piece engaging baffle protrusion with a tab that serves as a knob for removing the TE band when the lid is opened, the opening becomes easier. Further, the tongue piece is formed on the lower surface of the finger-hanging piece so as to project in an arc shape over a range of approximately 30 ° to 90 °, and on the engaging jaw portion formed on the outer peripheral surface of the tamper-evident band. A locking protrusion is formed to prevent a mischievous opening in an unopened state, and to perform a function to prevent residual liquid from splashing when the upper lid is closed again at the stage of use after opening. . When the installation range of the tongue piece is 30 ° or less, the effect of preventing the remaining liquid from scattering is small, and when it is 90 ° or more, it becomes unnecessarily large and material is wasted.

The hinge cap 1 according to this embodiment includes a cap body 2 and an upper lid 3 that is hinged to the cap body and is integrally formed. The hinge cap 1 is mounted by being plugged into the container opening 45. ing. The cap body 2 has a skirt wall 5 that hangs down from the top wall 4, and an annular protrusion 6 for engaging a container port is formed on the inner peripheral surface of the skirt wall to engage with a jaw formed on the outer peripheral part of the container port. Has been. Further, the top wall 4 has a tearing wall portion 8 surrounded by a score 7 that can be easily broken, and a pull ring 9 is formed to protrude on the upper surface of the top wall 4. 8 can be torn open. Further, a pour tube 10 is formed on the top surface of the top wall 4 so as to surround the tear wall portion 8, and an inner ring 11 is formed on the bottom surface so as to protrude from the inner peripheral surface of the container mouth. Further, in the vicinity of the outer peripheral edge of the top wall 4, an upper cover engaging annular protrusion 12 that engages with an annular recess 14 (FIG. 4) formed on the inner peripheral edge of the lower end of a skirt wall 18 of the upper cover 3 described later is formed.
[0010]
On the other hand, the upper lid 3 is hinged at the upper edge of the skirt wall of the cap body 2 via a central hinge piece 15 and a pair of connecting pieces 16 formed separately on both sides as shown in FIG. It is connected. The upper lid 3 has a top wall 17 and a skirt wall 18. The top wall 17 is fitted with a pour tube that fits the inner peripheral surface of the pour tube 10 of the cap body and seals the spout. An inner cylinder 19 is formed so as to protrude, and a finger-hanging piece 20 is formed so as to protrude from the edge opposite to the hinge portion.
[0011]
The above structure is the same as that of the conventional hinge cap, but the hinge cap 1 of the present embodiment is a tamper evidence that performs functions of “preventing mischief opening” and “proof of unopened upper lid” on the cap body 2. A band (hereinafter referred to as a TE band) 21 is provided, and a tongue piece 22 is provided on the upper lid 3 to perform the functions of “preventing mischief opening” and “preventing scattered liquid scattering when the upper lid is closed again”.
[0012]
The TE band 21 is hooked on the outer periphery of the skirt wall 2 opposite to the hinge portion of the cap body 2 in the range of about 30 ° to 90 ° of the skirt wall from the upper end of the skirt wall, preferably in a closed state. A concave portion 23 in which the skirt wall becomes thin is formed over the entire range where the pieces 20 face each other or 40 ° or more, and the concave portions 23 are opposed to each other at a predetermined interval and are connected by weakening portions 24 and 24 that can be broken at both ends. It is molded integrally with the skirt wall. As shown in FIGS. 1 and 4, the TE band 21 forms a gap in which the tongue piece 22 is fitted and locked with the outer peripheral wall surface 26 of the concave portion of the skirt wall 5 as clearly shown in FIGS. 1 and 4. A belt-like tongue-fitting engagement locking wall 25, a finger-hanging piece seat 27 formed on the upper surface of the finger-hanging piece in the same shape as the lower surface of the finger-hanging piece 20 and the outer periphery of the finger-hanging piece seat 27 An arcuate finger-engaging piece engaging baffle 28 that stands upright from the section and surrounds the outer peripheral surface of the finger-hanging piece in a closed state and prevents the finger from directly engaging the outer periphery of the finger-hanging piece in an unopened state, It is comprised from the knob | pick part 29 formed in the one side of the upper surface of the single engagement baffle protrusion 28. FIG. An engaging jaw 30 that engages with the locking protrusion 31 of the tongue piece is formed at the upper part of the inner peripheral surface of the tongue piece engaging locking wall portion 25.
[0013]
On the other hand, the tongue piece 22 is formed in a circular arc shape so as to hang from the lower surface of the finger cover piece 20 of the upper lid so as to fit into the concave portion 23 of the cap body, and the tongue piece fitting locking wall portion 25 is formed on the outer peripheral surface thereof. A locking protrusion 31 that locks the engaging jaw 30 is formed. When the upper lid 3 is closed from the state shown in FIG. 4, the locking protrusion 31 of the tongue piece 22 gets over the jaw 30 and fits into the recess 23, and is locked to the jaw 30 when the upper lid is opened. It cannot be opened unless the band is removed. In this state, the engaging portion between the locking ridge 31 of the tongue piece 22 and the jaw part 30 of the TE band is covered with the tongue band fitting locking wall part 25 of the TE band, and the upper surface is the finger-hooking piece 20. Therefore, a tool or the like cannot be inserted into the engaging portion, and the front edge of the finger hanging piece 20 is also surrounded by the finger hanging piece engaging baffle projection 28. Can't hang. Therefore, the upper lid cannot be opened unless the TE band is broken, and the TE property can be reliably ensured. In addition, in the present invention, the finger-hook engaging baffle 28 is formed on the TE band to prevent the finger from engaging the finger-hook, so that the engagement between the locking protrusion 31 and the jaw 30 is tight. Even without it, it is difficult to open the top lid illegally.
[0014]
The hinge cap according to the present embodiment has the following easy-to-separate disposal structure so that the cap can be easily separated from the container after use, and can be separated and discarded even if it is a stopper cap.
That is, as shown in FIG. 3, the skirt wall 5 of the container body 2 has an arc-shaped cut 34 from the upper surface of the skirt wall over a part of the side to which the upper lid 3 is hinged (approximately half a circumference in the illustrated embodiment). And is divided into a double wall of an inner peripheral wall portion 32 and an outer peripheral wall portion 33 in the thickness direction of the skirt wall. The outer peripheral wall 33 is provided with a breakable weakening line 36 located on both sides of the hinge connecting pieces 16 and 16 from the upper edge of the skirt wall to the lower end of the skirt wall, and the inner peripheral wall 32 has a weakening line 36. A weakening line extends from the lower end to a position beyond the annular projection 6 at a position corresponding to the outer peripheral wall portion that follows the hinge portion, and a tear wall 37 is formed. The notch 34 is formed between the weakening lines 36 so as to leave the connecting portion 35 at the lower portion of the skirt wall 5, and the lower end to the lower end of the skirt wall 5 in the region opposite to the hinge connecting portion from the weakening portion 36. It extends to the vicinity.
[0015]
Therefore, when discarding the container, when the upper lid 3 is opened and pulled outward, the tear wall 37 is pulled outward through the central hinge 15 and the hinge connecting pieces 16 and 16 on both sides, and the weakening lines 36 and 36 are broken. To do. Next, by pulling the tear wall 37 upward, the inner peripheral wall portion 32 of the skirt wall is pulled outward from the lower end via the connecting portion 35 at the lower end, the weakening line of the inner peripheral wall is broken, and the inner peripheral wall portion and the container The engagement with the mouth portion is loosened, and the outer peripheral wall portion 33 continuing from the tear wall 37 to the opposite side of the hinge connecting portion becomes a banded belt shape, and the holding force by the inner peripheral wall portion 32 is weakened. 1 can be removed from the container mouth. Therefore, even if it is a hinge cap, separation from the container opening after use is easy, separation disposal is promoted, and reuse of resources is promoted.
[0016]
The hinge cap of the present embodiment is configured as described above. In the state shown in FIGS. 3 and 4, the cap body 2 and the upper lid 3 are integrally formed of synthetic resin, and the upper lid 3 is inverted from the hinge portion after die cutting, The locking protrusion 31 of the tongue piece 22 gets over the jaw 30 and fits into the recess 23. Further, the annular recess 14 of the upper lid 3 and the annular protrusion 12 of the cap body are also engaged to maintain the closed state. In this state, as described above, the finger hanger piece 20 of the upper lid is placed on the finger hanger piece seat portion 27 and fits into the space surrounded by the finger hanger piece engagement baffle protrusion 28, and the outer peripheral surface of the finger hanger piece 20 is the finger hanger piece engagement baffle protrusion. Since it is surrounded by 28 and the bottom surface is surrounded by the finger-hanging piece seat 27, the finger-hanging piece 20 cannot be directly hooked unless the TE band 21 is removed. Therefore, it is not necessary to enlarge the protrusions and forcefully fit the tongue pieces to tighten the TE band protrusions as in the prior art. The TE band is formed by forcibly fitting the tongue pieces and the TE band. Accidents in which the weakened portion is accidentally damaged can be reduced, and the yield rate in the cap manufacturing process can be increased. In addition, by making the engagement protrusions small, there is also an advantage that unreasonable punching is eased at the time of die cutting after molding, and die cutting becomes easy.
[0017]
To open the lid from the closed state, the tab 29 is picked and pulled outward, whereby the weakened portion 24 near the tab is broken, and the TE band 21 can be rotated outward. The enclosure around the outer periphery of the tip edge of the finger-hanging piece can be opened so that it can be locked. At the same time, the engaging jaw 30 is also disengaged from the locking position with the locking protrusion 31, so that the upper lid can be easily opened by placing the finger on the finger-hanging piece and lifting it upward. The TE band 21 is completely removed from the cap body 2 so as not to obstruct the use after opening, as shown in FIG. 2, by pulling the TE band 21 so that tension is applied to the other weakened portion. be able to. In a state where one side weakened part of the TE band is broken or in a state where the TE band is removed, the concave part formed in the skirt wall and the broken state of the weakened part are easily noticeable, and at first glance, the upper lid may be opened by mischief. I understand that. In use after opening, when the upper lid is closed again after an arbitrary amount of content liquid is poured out, the tongue piece 22 of the upper lid engaging annular projection 12 is brought into contact with the upper lid engaging annular projection 12 before the upper lid skirt wall 18 hits. Since the front cover is covered, the spring force of the hinge portion when closing the upper cover 3 vigorously abuts the skirt wall of the upper cover and the content liquid adhering to the upper surface of the upper cover engaging annular protrusion 12 scatters forward. It is possible to prevent the user's clothes from being stained with the content liquid without being scattered.
[0018]
The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various design changes can be made within the scope of the technical idea. For example, in the above-described embodiment, the hinge cap has a pull ring on the top wall of the cap body. However, the present invention does not necessarily have a pull ring, and can be applied to a hinge cap in which a spout is formed in advance. Nor. Moreover, in the said embodiment, while forming the recessed part which a tongue piece fits into a cap main body, while saving the material of a skirt wall, it became possible to make the position of a tongue piece closer to a content liquid adhesion position, Although the scattering prevention effect is enhanced, the recess may not necessarily be formed in the skirt wall, and the tongue piece may be fitted directly between the outer wall surface of the skirt wall.
[0019]
【The invention's effect】
As described above, according to the present invention, it is impossible to directly touch the lower surface or the leading edge of the finger cover piece of the upper lid and the engaging portion of the upper lid and the tamper evidence band in the unopened state. It is possible to reliably prevent the opening of the top cover due to tampering without increasing the size, to improve the yield rate of productivity, and to have excellent unopened proof properties that can easily determine whether or not the top cover has been opened. A hinge cap in which TE property is added to the upper lid that can prevent the remaining liquid adhering to the outer peripheral surface of the cap body at the time of the lid from scattering forward can be obtained.
