Description

The present invention relates to a hinge cap.

Conventionally, as a cap to be attached to the mouth of the container body, the cap body is attached to the mouth of the container body in which the contents are housed, and a spout for pouring out the contents is formed, and the cap body. A hinge cap including a lid that is rotatably connected around a hinge to cover the spout so that it can be opened and closed, and a plug that is connected to the spout opening edge via a weakening portion to close the spout. It has been known.
In the hinge cap configured in this way, the spout can be opened by removing the plug-out portion while breaking the weakened portion by pulling up the pull ring provided in the plug-out portion.

However, with the conventional hinge cap, when the hinge cap is opened by pulling up the pull ring, the unplugging portion tends to open vigorously, and the contents may jump out and scatter to the surroundings. In particular, when the contents are filled in the container body at a high temperature, the inside of the container body is in a decompressed state at the time of product shipment, so that the outside air vigorously enters the container body due to the breakage of the weakened portion. Therefore, the contents are in a wavy state due to the inflow of outside air, and the above-mentioned scattering is likely to occur.

Therefore, in order to suppress the scattering of such contents, for example, as shown in Patent Document 1 below, a hinge cap provided with a projecting piece for preventing liquid splashing is known.

Japanese Patent No. 4560349

However, in the above-mentioned conventional hinge cap, since it is necessary to pull up the pull ring after removing the lid body from the cap body, there is room for improvement in operability at the time of opening. Furthermore, the pull ring may be pulled up and operated with a large operating force, and there is still a risk that the contents may be scattered due to the momentum.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a hinge cap capable of improving operability at the time of opening and suppressing scattering of contents. That is.

(1) The hinge cap according to the present invention is attached to the mouth of the container body in which the contents are housed, and has a cap body having a spout for pouring out the contents, and the cap body around the hinge part. A lid that is rotatably connected to cover the spout so that it can be opened and closed, and a plug plate that closes the spout by being connected to the opening edge of the spout via a breakable weakening portion. A connecting body that integrally connects the lid body and the plugging plate is provided, and the plugging plate continuously breaks the weakened portion as the lid body is opened around the hinge portion. However, it is possible to detach from the spout, and a scattering suppressing portion that suppresses scattering of the contents is provided by temporarily suppressing the disconnection of the plugging plate from the spout during the breakage of the weakened portion. It is characterized by being.

According to the hinge cap according to the present invention, since the plugging plate blocking the spout and the lid are integrally connected via the connecting body, the lid can be rotated around the hinge portion. The unplug plate can be rotated together with the lid. As a result, an external force can be applied to the stopper plate as the lid is opened, and the stopper plate can be pulled up and gradually separated from the spout while breaking the weakened portion. As a result, the spout can be opened when the opening operation of the lid is completed. In this way, since the spout can be opened at the same time as the lid is opened, the operability at the time of opening can be improved.

In particular, when the plugging plate is pulled up while breaking the weakened portion due to the opening operation of the lid, for example, a load (resistance) is applied to the plugging plate by using the scattering suppression portion during the process (during the breaking of the weakened portion). Force) can be applied to temporarily prevent the plugging plate from coming off from the spout. Thereby, the opening operation of the lid body and the pulling operation of the plug removal plate can be delayed or stopped momentarily, for example, and it is possible to suppress the vigorous inflow of outside air into the container body. As a result, it is possible to prevent the inconvenience that the contents jump out and scatter to the surroundings.
Further, unlike the conventional case where the pull ring is pulled up to open the seal, the opening is performed in conjunction with the opening operation of the lid, so it is difficult to perform an operation in which the unplugging plate is strongly pulled up. Moreover, since it is possible to suppress the opening operation of the lid body and the pulling operation of the plug removal plate on the way, it is also possible to prevent the contents from being scattered.

(2) The unplugging plate is located on the side opposite to the fracture start end portion with the cap shaft sandwiched between the fracture start end portion and the fracture start end portion in a plan view from the cap axis direction, and is located on the hinge portion side. The outer shape is formed into a circular shape having a fracture end end portion, and the weakened portion is formed in an annular shape corresponding to the outer shape of the plug removal plate, and the outer peripheral edge portion of the plug removal plate and the opening of the spout port are opened. The edge portion is connected over the entire circumference, and the scattering suppressing portion is formed from a portion of the outer peripheral edge portion of the plugging plate located between the fracture start end portion and the fracture end end portion. It may have a recessed portion formed so as to be recessed toward the inside of the.

In this case, the plug removal plate can be pulled up from the fracture start end side by opening the lid. Therefore, the weakened portion located on the breaking start end side can be broken first, and the weakened portion is gradually broken toward the breaking end end side with the opening operation of the lid and the pulling operation of the plug removal plate. Can be advanced to. At this time, since the weakened portion is provided corresponding to the outer shape of the plugging plate formed in a circular shape (for example, a perfect circle or an oval shape such as an oval or an ellipse), it accompanies the pulling operation of the plugging plate. Therefore, the weakened portion can be continuously and smoothly broken. In addition, since a recess is formed on the outer peripheral edge of the plugging plate, the direction of fracture of the weakened portion can be locally changed at this recess, and the progress of fracture can be momentarily delayed or It can be stopped.
As a result, the opening operation of the lid body and the pulling operation of the plug removal plate can be instantaneously delayed or stopped, which can lead to the suppression of scattering of the contents.

(3) The recessed portion may be arranged closer to the fracture start end portion than the cap shaft in a plan view seen from the cap axis direction.

In this case, since the progress of the breakage can be momentarily delayed or stopped at the initial stage of the opening operation of the lid and the pulling operation of the unplugging plate, for example, the outside air vigorously blows into the container body at the initial stage of opening. The inflow can be suppressed, and the scattering of the contents can be effectively suppressed.

(4) The scattering suppressing portion has a projecting piece formed so as to extend along the outer peripheral edge portion of the plugging plate and project from the plugging plate toward the container body side, and the projecting piece has a projecting piece. With the detachment of the plugging plate from the spout, the opening edge of the spout may be brought into contact with the container body side.

In this case, when the plug pulling plate is pulled up while breaking the weakened portion in accordance with the opening operation of the lid, the projecting piece can be brought into contact with the opening edge of the spout from the container body side. As a result, it is possible to apply a resistance force to the plugging plate by utilizing the contact resistance of the projecting piece, and it is possible to temporarily prevent the plugging plate from coming off from the spout. As a result, the opening operation of the lid body and the pulling operation of the plug removal plate can be delayed or stopped momentarily, for example, and the scattering of the contents can be suppressed.

According to the hinge cap according to the present invention, the operability at the time of opening can be improved and the scattering of the contents can be suppressed. Therefore, it is very easy to use, and can be suitably used particularly for a container body in which the contents are filled at a high temperature.

(First Embodiment)
The first embodiment of the hinge cap according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the hinge cap 1 of the present embodiment is attached to the mouth portion 2a of the bottomed cylindrical container body 2 in which the contents are housed, and the pouring port 11 for pouring out the contents. The cylindrical cap body 10 on which the is formed is connected to the cap body 10 via a hinge portion 12, and the eclipsed tubular lid body 13 that covers the spout 11 so as to be openable and closable, and the opening of the spout 11. A plug-out plate 15 that closes the spout 11 by being connected to the edge portion via a weakening portion 14 and a connecting body 16 that integrally connects the lid 13 and the plug-out plate 15 are provided. The cap body 10, the lid body 13, the plug removal plate 15, and the connecting body 16 are integrally formed.

The hinge cap 1 and the container body 2 are arranged with their respective central axes positioned on a common axis. In the present embodiment, this common shaft is referred to as a cap shaft O1, the lid 13 side along the cap shaft O1 is referred to as an upper side, and the container body 2 side is referred to as a lower side. Further, in a plan view from the direction of the cap shaft O1, the direction intersecting the cap shaft O1 is referred to as the radial direction, and the direction of orbiting around the cap shaft O1 is referred to as the circumferential direction.
Further, one of the radial directions orthogonal to each other is referred to as a front-rear direction L1, and the other direction is referred to as a left-right direction L2. Further, in the front-rear direction L1, the hinge portion 12 side is the rear side, and the opposite side is the front side.

As shown in FIG. 1, a first engaging protrusion 3 protruding outward in the radial direction is formed on the outer peripheral surface of the mouth portion 2a of the container body 2. The first engaging projections 3 may be formed in an annular shape, or may be formed in plurality at intervals in the circumferential direction.
The case is not limited to the case where the first engaging protrusion 3 is formed, and for example, a male screw portion may be formed on the outer peripheral surface of the mouth portion 2a of the container body 2 instead of the first engaging protrusion 3. ..

The contents contained in the container body 2 are not particularly limited, but for example, fluid contents such as liquid foods and liquid seasonings can be preferably used. Further, as the contents, for example, powdery contents such as salt, powdered food seasoning, and wheat flour, and granular contents such as fertilizer and herbicide can be used.

The cap body 10 has a ridged tubular inner plug 20 that closes the inside of the mouth portion 2a of the container body 2, a seal cylinder 21 that is fitted inside the mouth portion 2a, and the mouth portion 2a on the outside in the radial direction. It is provided with a mounting cylinder 22 that surrounds the surface.

The inner plug 20 is connected to the disk-shaped top wall portion 20a on which the spout 11 is formed and the outer peripheral edge portion of the top wall portion 20a over the entire circumference, and extends downward from the outer peripheral edge portion. The peripheral wall portion 20b and the peripheral wall portion 20b are formed in a climax cylinder shape.
In the illustrated example, the inner plug 20 is arranged above the mouth portion 2a of the container body 2. However, the position of the inner plug 20 with respect to the mouth portion 2a of the container body 2 is not limited to this case, and may be arranged so as to be located inside the mouth portion 2a of the container body 2, for example.

At the lower end of the peripheral wall portion 20b, an annular flange portion 23 is formed which extends outward in the radial direction and is arranged on the upper end opening end of the mouth portion 2a of the container body 2. The upper end portion of the seal cylinder 21 and the upper end portion of the mounting cylinder 22 are integrally formed on the flange portion 23. As a result, the seal cylinder 21 and the mounting cylinder 22 are integrally connected to the inner plug 20 via the flange portion 23.

The flange portion 23 is formed with an annular support cylinder 24 that projects upward and supports the lid 13 from below. Further, an annular groove 22a opened upward is formed at the upper end of the mounting cylinder 22. However, the annular groove 22a is not essential and may not be provided.
Further, although not shown, a structure may be provided in which the hinge cap 1 can be separated from the mouth portion 2a of the container body 2. In this case, for example, a vertical weakening portion is provided near the hinge portion 12 of the mounting cylinder 22 in the hinge cap 1, and a circumferential weakening portion is provided from the vertical weakening portion (starting point) along the bottom surface of the annular groove 22a. It is formed over about 270 ° (end point). It should be noted that the annular groove 22a is not provided at the end point position of the weakened portion in the circumferential direction, and the wall thickness portion is indestructible. When sorting in such a structure, the weakened portion is broken from the vertically weakened portion (start point) to the circumferential weakened portion (end point), and the lid 13 is pulled up to pass the container body through the inbreakable thick portion. The cap body 10 can be removed from the mouth portion 2a of 2, and the entire hinge cap 1 can be removed.

The seal cylinder 21 and the mounting cylinder 22 are fitted and fixed to the mouth portion 2a by, for example, inserting the mouth portion 2a into the mounting groove 25 formed between the seal cylinder 21 and the mounting cylinder 22 by tapping. Has been done. At this time, since the seal cylinder 21 and the mounting cylinder 22 sandwich the mouth portion 2a from the inside and outside, they are mounted on the mouth portion 2a with a strong fitting force. The seal cylinder 21 is, for example, airtightly fitted inside the mouth portion 2a of the container body 2, and appropriately seals the inside of the container body 2.

In the illustrated example, the mounting cylinder 22 is undercut fitted to the mouth portion 2a of the container body 2. Specifically, on the inner peripheral surface at the lower end of the mounting cylinder 22, a second engaging protrusion 26 that engages with the first engaging protrusion 3 formed on the outer peripheral surface of the mouth portion 2a is radially inward. The second engaging projection 26 is undercut fitted to the first engaging projection 3.
The second engaging protrusions 26 may be formed in an annular shape as long as they can be undercut and fitted to the first engaging protrusions 3, and a plurality of the second engaging protrusions 26 may be formed at intervals in the circumferential direction. It doesn't matter if you do.

However, the method of mounting the mounting cylinder 22 to the mouth portion 2a of the container body 2 is not limited to undercut fitting by tapping or the like. For example, as described above, when the male threaded portion is formed on the outer peripheral surface of the mouth portion 2a of the container body 2, the female threaded portion screwed to the male threaded portion is formed on the inner peripheral surface of the mounting cylinder 22. The mounting cylinder 22 may be mounted on the mouth portion 2a of the container body 2 by screwing.

A pouring cylinder 27 projecting upward is formed on the outer peripheral edge of the top wall portion 20a of the inner plug 20. The pouring cylinder 27 communicates with the inside of the container body 2 through the pouring outlet 11. Therefore, it is possible to discharge the contents to the outside through the inside of the dispensing cylinder 27.
The injection cylinder 27 is arranged coaxially with the cap shaft O1 and is formed so that the inner diameter on the upper end side gradually increases as the inner diameter increases upward. Therefore, it is possible to dispense the contents through the dispensing cylinder 27.

In the illustrated example, the protruding height of the dispensing cylinder 27 is not the same over the entire circumference, but changes along the circumferential direction. Specifically, the dispensing cylinder 27 is formed so that the top portion 27a having the highest protrusion height is located on the front side and the low position portion 27b having the lowest protrusion height is located on the rear side. As a result, the dispensing cylinder 27 is formed so that the top portion 27a and the low position portion 27b face each other in the radial direction with the cap shaft O1 in between.
Since the dispensing cylinder 27 is formed in this way, it is possible to easily dispense the contents by tilting the container body 2 forward so that the top 27a faces downward. ..

The lid 13 is formed in an eclipsed cylinder shape provided with a peripheral wall 30 and a top wall 31, covers the entire top wall portion 20a and the dispensing cylinder 27 of the cap body 10 from above, and around the hinge portion 12. It is possible to open and close the spout 11 by rotating it.

The lower end side of the peripheral wall 30 is detachably fitted to the support cylinder 24 in the cap body 10. As a result, the lid body 13 is supported in a state of being positioned by the support cylinder 24. The hinge portion 12 integrally connects the lower end portion of the peripheral wall 30 of the lid body 13 and the upper end portion of the mounting cylinder 22 of the cap body 10.

The hinge portion 12 is formed at the rear portion of the peripheral wall 30 and the mounting cylinder 22, and is arranged so that the position in the circumferential direction is the same as that of the low position portion 27b of the dispensing cylinder 27. As a result, the lid 13 can be opened toward the side opposite to the top 27a of the dispensing cylinder 27 in the radial direction, that is, toward the rear side.

A picking piece 32 protruding outward in the radial direction is formed in a front portion of the peripheral wall 30 of the lid 13 located on the opposite side of the cap shaft O1 from the hinge portion 12. By using the picking piece 32, it is possible to easily open and close the lid 13 around the hinge portion 12.

On the top wall 31 of the lid 13, a closing cylinder 33 that projects downward and is detachably fitted inside the dispensing cylinder 27 is formed coaxially with the cap shaft O1. By fitting the closing cylinder 33 inside the dispensing cylinder 27, it is possible to seal the inside of the dispensing cylinder 27.

Further, a connecting hole 34 is formed in a portion of the top wall 31 located in front of the cap shaft O1 so as to penetrate the top wall 31 in the vertical direction as shown in FIGS. 1 and 2. The connecting hole 34 is formed in a circular shape in a plan view centered on the connecting shaft O2, and is arranged so as to be located above the plug removal plate 15.
As shown in FIG. 2, the connecting hole 34 is formed in a vertical cross-sectional taper shape in which the opening diameter gradually increases from the upper side to the lower side. However, the present invention is not limited to this case, and the connecting hole 34 may be formed in a straight shape having a uniform opening diameter in the vertical direction.
Further, as shown in FIG. 1, a connecting recess 35 having a circular shape in a plan view having a diameter larger than that of the connecting hole 34 is formed coaxially with the connecting shaft O2 on the upper surface of the top wall 31. As a result, the connecting recess 35 is continuously provided with respect to the connecting hole 34.

As shown in FIGS. 1 and 2, the unplugging plate 15 is arranged inside the spout 11 in a state of being arranged coaxially with the cap shaft O1. The unplugging plate 15 is connected to the opening edge portion at the spout 11 via the weakening portion 14 as described above. Further, the unplugging plate 15 is integrally connected to the lid 13 via the connecting body 16, and can be separated from the spout 11 while breaking the weakened portion 14 as the lid 13 around the hinge portion 12 is opened. It is said that.

The unplugging plate 15 is formed in a substantially elliptical shape in a plan view seen from the cap axis O1 direction, in which the length along the front-rear direction L1 is longer than the length along the left-right direction L2.
This will be described in detail.
The portion of the unplugging plate 15 located on the front side is a fracture start end portion 40 that first breaks the weakened portion 14 by being pulled upward first as the lid body 13 is opened. .. On the other hand, the portion of the unplugging plate 15 located on the rear side (hinge portion 12 side) is finally pulled upward in accordance with the opening operation of the lid body 13 to break the weakened portion 14. It is said to be the fracture end end 41 to be terminated.

The fracture start end 40 and the fracture end end 41 are arranged along the front-rear direction L1 and are arranged so as to be located on opposite sides in the radial direction with the cap shaft O1 interposed therebetween. In the illustrated example, the fracture start end 40 is formed in an arc shape that bulges forward. Further, the fracture end end portion 41 is formed in an arc shape that bulges convexly toward the rear. The fracture end end 41 is formed in an arc shape with a curvature larger than the curvature of the fracture start end 40.

Of the unplugging plates 15, a pair of intermediate portions 42, which are arranged along the left-right direction L2 and are located on opposite sides in the radial direction with the cap shaft O1 in between, bulge convexly toward the outside of the left-right direction L2. It is formed in an arc shape. Therefore, the unplugging plate 15 has the widest length along the left-right direction L2 in the middle portion in the front-rear direction L1 including the pair of intermediate portions 42.

The unplugging plate 15 is externally formed so as to smoothly and continuously connect the above-mentioned fracture start end portion 40, fracture end end portion 41, and pair of intermediate portions 42 along the circumferential direction. By the way, in the portion of the outer peripheral edge of the plug plate 15 located between the fracture start end 40 and the fracture end end 41, a recess 43 formed so as to be recessed toward the inside of the plug plate 15 is provided. It is formed.

The recessed portions 43 are arranged closer to the fracture start end portion 40 than the cap shaft O1 and are formed in pairs so as to face each other in the left-right direction L2. Specifically, the recessed portion 43 is arranged so as to be located between the fracture start end portion 40 and the pair of intermediate portions 42, and is formed in an arc shape that is recessed inward in the radial direction.

Since the unplugging plate 15 is formed in the outer shape as described above, the unplugging plate 15 is formed so as to be confined in the recess 43 in a plan view seen from the direction of the cap shaft O1.
The recessed portion 43 functions as a scattering suppressing portion 45 that suppresses scattering of the contents by temporarily suppressing the removal of the plugging plate 15 from the spout 11 during the breaking of the weakening portion 14. This point will be described later.

By the way, the spout 11 formed in the top wall portion 20a of the cap body 10 is formed so as to open corresponding to the outer shape of the plug removal plate 15, and is slightly larger than the outer shape size of the plug removal plate 15. It is formed to have an opening size.
Further, the weakening portion 14 is formed in an annular shape corresponding to the outer shape of the plug removal plate 15, and connects the outer peripheral edge portion of the plug removal plate 15 and the opening edge portion of the spout 11 over the entire circumference. The weakened portion 14 is formed to be thinner than the thickness of the top wall portion 20a and the plugging plate 15 so that it can be easily broken, and the weakened portion 14 continuously extends over the entire circumference with a uniform thickness.

The connecting body 16 is integrally formed with the plug removal plate 15 and is locked to the lid body 13. As a result, the connecting body 16 integrally connects the plugging plate 15 and the lid body 13.
The connecting body 16 is formed so that the strut portion 50 is formed so as to project upward from the plug removal plate 15 and the strut portion 50 is formed so as to project further upward from the upper end portion of the strut portion 50, and the top wall of the lid 13 is formed. A locking portion 51 locked in the connecting hole 34 and the connecting recess 35 formed in the 31 is provided.

The strut portion 50 is formed so as to project upward from the vicinity of the fracture start end portion 40 of the plug removal plate 15, and is arranged coaxially with the connecting shaft O2. The strut portion 50 has a protruding height at which the upper end portion contacts the top wall 31 of the lid 13 from below.
At the lower end of the support column 50, a lightening recess 50a that is recessed upward is formed. However, the lightening recess 50a is not essential and may not be provided.

Further, a reinforcing rib 55 is integrally formed in a portion of the support column 50 located at the rear. The lower end of the reinforcing rib 55 is integrally formed on the upper surface of the plug removal plate 15. In the illustrated example, the reinforcing rib 55 is formed in a side view triangular shape in which the rear end edge is inclined forward from the lower end portion toward the upper end portion.

The locking portion 51 enters the connecting hole 34 and the connecting recess 35 formed in the top wall 31 from below. The locking portion 51 includes a first locking portion 52 arranged inside the connecting hole 34 and a second locking portion 53 arranged inside the connecting recess 35. The second locking portion 53 is locked so that the upper end surface is flush with the upper end surface of the top wall 31 of the lid 13 and is in contact with the bottom of the connecting recess 35 from above. ..

The connecting body 16 configured as described above can be moved following the lid body 13 by locking the locking portion 51 in the connecting hole 34 and the connecting recess 35, whereby the plug can be unplugged. It is possible to move the plate 15 together with the lid 13 around the hinge portion 12.

The locking portion 51 is formed in a triangular shape in a side view so as to project upward from the top wall 31 of the lid 13 as shown in FIG. 3 when the hinge cap 1 is manufactured. Then, from this state, the portion of the locking portion 51 that protrudes upward from the top wall 31 is pressed and crushed while being heated by, for example, a hot plate, as shown by the arrow in FIG. As shown in 1, the locking portion 51 having the first locking portion 52 and the second locking portion 53 can be used.
The hinge cap 1 is attached to the mouth portion 2a of the container body 2 by using a stopper (not shown) or the like after filling the container body 2 with the contents at a high temperature, for example. After that, the entire container body 2 to which the hinge cap 1 is attached is sterilized by heating and then cooled by cooling water or the like.

(Action of hinge cap)
The operation of the hinge cap 1 configured as described above will be described.
When the product is unopened, such as during product transportation or product distribution, as shown in FIG. 1, a plugging plate 15 connected to the opening edge of the spout 11 via a weakening portion 14 closes the spout 11. .. As a result, the inside of the container body 2 can be sealed, and leakage of the contents to the outside can be appropriately prevented.

Next, when the contents are to be poured out, the lid 13 is opened around the hinge portion 12 by using the picking piece 32 or the like. At this time, since the top wall 31 of the lid body 13 and the plugging plate 15 are integrally connected via the connecting body 16, the plugging plate 15 can be rotated around the hinge portion 12 together with the lid body 13.
As a result, an external force can be applied to the plugging plate 15 as the lid 13 is opened, and the plugging plate 15 can be pulled upward while breaking the weakened portion 14 and gradually separated from the spout 11. .. As a result, the spout 11 can be opened when the opening operation of the lid 13 is completed. In this way, since the spout 11 can be opened at the same time as the lid 13 is opened, the operability at the time of opening can be improved.

By tilting the container body 2 forward after opening the container, the top portion 27a of the dispensing cylinder 27 can be turned downward. Thereby, the contents in the container main body 2 can be poured out from the top 27a of the pouring cylinder 27 to the outside. Further, by closing the lid 13 around the hinge portion 12 after pouring out the contents, the pouring cylinder 27 can be appropriately sealed by using the closing cylinder 33.

In particular, according to the hinge cap 1 of the present embodiment, when the plugging plate 15 is pulled up while breaking the weakened portion 14 with the opening operation of the lid body 13, note in the middle (during the breaking of the weakened portion 14). It is possible to temporarily prevent the unplugging plate 15 from coming off from the outlet 11.
This will be described in detail.
When the lid body 13 is opened around the hinge portion 12, an external force is first applied to the fracture start end portion 40 located on the side opposite to the hinge portion 12 in the radial direction across the cap shaft O1 of the plug removal plate 15. Since it can be transmitted, the plug removal plate 15 can be pulled up from the fracture start end 40 side. Therefore, as shown in FIG. 4, the weakened portion 14 located on the breaking start end 40 side can be broken first, and then broken with the opening operation of the lid 13 and the pulling operation of the plug removal plate 15. The breaking of the weakened portion 14 can be gradually advanced toward the end end portion 41 side.

In particular, since the reinforcing rib 55 is formed on the support column 50 in the connecting body 16 that connects the lid 13 and the plugging plate 15, the support column 50 can be made difficult to deform. Therefore, by opening the lid body 13, stress can be easily concentrated on the fracture start end 40 side of the plug removal plate 15, and the weakened portion 14 located on the fracture start end 40 side is surely broken first. It becomes possible.

When the weakened portion 14 is broken as described above, since the recessed portion 43 is formed on the outer peripheral edge portion of the plug removal plate 15, the direction of the fracture of the weakened portion 14 is locally changed at the recessed portion 43. It is possible to momentarily delay or stop the progress of fracture. As a result, the opening operation of the lid body 13 and the pulling operation of the plug removal plate 15 can be momentarily delayed or stopped, and the state shown in FIG. 4 can be temporarily maintained.

Therefore, it is possible to prevent the outside air from flowing into the container body 2 vigorously. As a result, it is possible to prevent the inconvenience that the contents jump out and scatter to the surroundings.
Further, unlike the conventional case where the pull ring is pulled up to open the seal, the opening is performed in conjunction with the opening operation of the lid body 13, so that it is difficult to perform an operation in which the unplugging plate 15 is strongly pulled up. Moreover, since it is possible to suppress the opening operation of the lid 13 and the pulling operation of the plugging plate 15 on the way, it is also possible to prevent the contents from being scattered.

As described above, according to the hinge cap 1 of the present embodiment, it is possible to improve the operability at the time of opening and suppress the scattering of the contents. Therefore, it is very easy to use, and can be suitably used particularly for the container body 2 in which the contents are filled at a high temperature.

Further, since the recessed portion 43 formed in the outer peripheral edge portion of the plug removal plate 15 is arranged on the fracture start end portion 40 side of the cap shaft O1 in a plan view from the direction of the cap shaft O1, the lid body 13 In the initial stage of the opening operation and the pulling operation of the unplug plate 15, the progress of the breakage can be momentarily delayed or stopped. Therefore, it is possible to suppress the vigorous inflow of outside air into the container body 2 at the initial stage of opening, and it is possible to effectively suppress the scattering of the contents.

(Modified example of the first embodiment)
In the first embodiment, the case where the recessed portion 43 is arranged on the fracture start end portion 40 side of the outer peripheral edge portion of the plug removal plate 15 with respect to the cap shaft O1 has been described as an example, but the present invention is limited to this case. It's not something. For example, as shown in FIG. 5, the recessed portion 43 is formed in a portion of the outer peripheral edge portion of the plug removal plate 15 located closer to the fracture end end portion 41 than the cap shaft O1 and is recessed inward in the radial direction. It may be formed in an arc shape.
Even in this case, the same effects as those in the first embodiment can be achieved.

(Second Embodiment)
Next, a second embodiment of the hinge cap according to the present invention will be described with reference to the drawings. In the second embodiment, the same parts as the components in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
In the first embodiment, the recessed portion 43 is formed on the outer peripheral edge of the plugging plate 15 so as to temporarily prevent the plugging plate 15 from coming off from the spout 11, but in the present embodiment, the plugging plate 15 is temporarily prevented from being separated. The protrusions formed on the unplugging plate 15 are used to temporarily suppress the detachment of the unplugging plate 15.

As shown in FIG. 6, in the hinge cap 60 of the present embodiment, a projecting piece 61 is formed so as to project downward from the lower end surface of the stopper plate 15 on the fracture start end 40 side.
The projecting piece 61 functions as a scattering suppressing portion 45 in the present invention, is formed in an arc shape in a plan view so as to extend along the outer peripheral edge portion of the plug removal plate 15, and gradually moves forward as it goes downward. It is formed so as to extend toward. Therefore, the projecting piece 61 is formed so as to project diagonally downward toward the front. At this time, the lower end portion of the projecting piece 61 protrudes forward to the extent that it exceeds the weakened portion 14 and enters below the top wall portion 20a of the cap body 10.
As a result, when the lid 13 is opened around the hinge portion 12, the projecting piece 61 comes into contact with the opening edge of the spout 11 from below as the plug plate 15 is detached from the spout 11. It is possible.

As shown in FIG. 7, the unplugging plate 15 of the present embodiment does not have the recessed portion 43 of the first embodiment. Therefore, the unplugging plate 15 smoothly and continuously connects the breaking start end portion 40, the breaking end end portion 41, and the pair of intermediate portions 42 along the circumferential direction in a plan view from the direction of the cap shaft O1 in the front-rear direction. It is formed in a substantially elliptical shape in which the length along L1 is longer than the length along L2 in the left-right direction.

(Action of hinge cap)
In the case of the hinge cap 60 of the present embodiment formed as described above, as shown in FIG. 8, the stopper plate 15 is pulled up while breaking the weakened portion 14 as the lid 13 is opened. At this time, the projecting piece 61 can be brought into contact with the opening edge of the spout 11 from below.
As a result, a load (resistance force) can be applied to the plugging plate 15 by utilizing the contact resistance of the projecting piece 61, and it is possible to temporarily prevent the plugging plate 15 from coming off from the spout 11. ..

Therefore, even with the hinge cap 60 of the present embodiment, as in the first embodiment, the opening operation of the lid body 13 and the pulling operation of the plug removal plate 15 can be delayed or stopped momentarily, for example, and the contents can be stopped. Scattering can be suppressed.

In the present embodiment, the projecting piece 61 is formed so as to project downward from the lower end surface of the unplugging plate 15 on the fracture start end 40 side. A plurality of projecting pieces 61 may be formed by opening them. In this case, since a plurality of projecting pieces 61 can be brought into contact with the opening edge of the spout 11 when the plug 15 is pulled up, it is more effective that the plug 15 is separated from the spout 11. It is possible to temporarily suppress it.
Further, the lower end side of the projecting piece 61 may be divided in the circumferential direction by forming a slit upward from the lower end portion of the projecting piece 61. In this case, since the lower end portion of the projecting piece 61 is easily deformed flexibly, the projecting piece 61 can be brought into contact with the opening edge portion of the spout 11 in a more intimate state, and the plug is removed from the spout 11. It is possible to temporarily prevent the plate 15 from coming off more effectively.

(Third Embodiment)
Next, a third embodiment of the hinge cap according to the present invention will be described with reference to the drawings. In the third embodiment, the same parts as the components in the second embodiment are designated by the same reference numerals, and the description thereof will be omitted.
In the second embodiment, the protrusion 61 formed on the plugging plate 15 is used to temporarily suppress the detachment of the plugging plate 15, but in the present embodiment, the shape of the plugging plate 15 itself is used to temporarily suppress the detachment of the plugging plate 15. Temporarily suppress withdrawal.

As shown in FIG. 9, the hinge cap 70 of the present embodiment is formed so that the plugging plate 15 itself is curved downward. In the illustrated example, the central portion of the plugging plate 15 in the front-rear direction L1 is smoothly curved so as to bulge downward so as to be the lowermost portion.
The outer shape of the plug removal plate 15 seen from the cap shaft O1 direction is the same as that of the second embodiment.

(Action of hinge cap)
In the case of the hinge cap 70 of the present embodiment formed as described above, when the plugging plate 15 is pulled up while breaking the weakened portion 14 with the opening operation of the lid body 13, it is bent downward in advance. Since the unplugging plate 15 is pulled up, the unplugging plate 15 can be temporarily made difficult to bend in the middle of the process. Therefore, it is possible to temporarily prevent the plugging plate 15 from coming off from the spout 11.
Therefore, even with the hinge cap 70 of the present embodiment, as in the second embodiment, the opening operation of the lid body 13 and the pulling operation of the plug removal plate 15 can be delayed or stopped momentarily, for example, and the contents can be stopped. Scattering can be suppressed.

Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention.

For example, in each of the above embodiments, the cap body 10 is provided with the dispensing cylinder 27, but the dispensing cylinder 27 is not essential and may not be provided.
Further, in each of the above embodiments, a connecting body 16 having a support column portion 50 and a locking portion 51 is provided, and the connecting body 16 is integrally formed with the plug removal plate 15 and then locked with respect to the lid body 13. Although the explanation has been given as an example, the present invention is not limited to this case.
For example, if the lid body 13 and the plugging plate 15 can be integrally connected, for example, the connecting body 16 may have a multi-part configuration, or the connecting body 16 may be formed separately from the lid body 13 and the plugging plate 15, and may be fitted or the like. The lid body 13, the plug removal plate 15 and the connecting body 16 may be integrally combined depending on the method. Further, the lid body 13 and the plugging plate 15 may be integrally connected by forming the connecting body 16 integrally with the lid body 13 and then locking the connecting body 16 to the plugging plate 15. In this case, for example, the connecting body 16 is projected downward from the lower surface of the top wall 31 of the lid body 13, and a connecting mechanism that can be locked with the connecting body 16 is provided on the upper surface of the plug removal plate 15 so as to stand up. It is possible to configure by.

Further, in each of the above embodiments, the weakened portion 14 is formed with a uniform thickness over the entire circumference, but the present invention is not limited to this case, and the thickness may be changed, for example. For example, the weakened portion 14 may be formed so that the thickness of the unplugging plate 15 on the side of the fracture start end 40 is thin and the other portions are thick.
By changing the thickness of the weakened portion 14 in this way, it is possible to temporarily prevent the plugging plate 15 from coming off from the spout 11 during the breakage of the weakened portion 14, and the contents can be scattered. It becomes possible to suppress.
Furthermore, by locally widening the width of the weakened portion 14 instead of changing the thickness, it is possible to temporarily prevent the plugging plate 15 from coming off from the spout 11 during the breakage of the weakened portion 14. It may be configured as. Further, in this case, the change in the width of the weakened portion 14 and the change in the thickness may be combined.

Further, the thickness of the unplugging plate 15 is changed by reducing the thickness of the unplugging plate 15 on the breaking start end 40 side and making the thickness of the breaking end end 41 side thicker than the breaking start end 40 side. You can put it on. Even in this case, it is possible to temporarily prevent the plugging plate 15 from coming off from the spout 11 when the wall thickness changes.
