Description

The present invention relates to a hinge cap.

Conventionally, a hinge cap that can be opened only by opening the lid without pulling up the pull ring after opening the lid has been known. For example, Patent Document 1 below discloses a cap comprising a lid and a cap base having a top wall to which the separating pieces are connected via a weakened portion. According to this cap, the weakened portion is broken when the lid is first opened, and the separated pieces are transferred to the lid side, so that the portion to which the separated pieces are connected is opened and the container is opened.

JP-A-2015-34012

When using this type of hinge cap, the separator remains attached to the lid once the container has been opened. However, in the case of a cap having a structure in which a separating piece is fitted to a tubular portion of a lid as in Patent Document 1, the separating piece may rotate about an axis of the tubular portion. However, if the separated piece rotates with the lid open, the separated piece may interfere with the peripheral portion of the spout and the lid may not close depending on the shape of the separated piece and the degree of rotation. In that case, in order to close the lid, the user needs to rotate the separated piece to return it to the original position, which reduces the usability during the closing operation. Therefore, it is desired to improve the usability when closing the lid in the hinge cap having the structure in which the closed body of the spout is transferred to the lid.

One aspect of the present invention is to solve the above-mentioned problems, and to improve the usability when closing the lid in a hinge cap that can be opened by rotating the lid. One of the purposes is to provide a hinge cap that can be used.

In order to achieve the above object, the hinge cap of one aspect of the present invention is attached to the mouth of the container body in which the contents are housed, and the cap body is formed with a spout for pouring out the contents. A ridged tubular lid that is rotatably connected to the cap body around a hinge and covers the spout so as to be openable and closable, and is connected to the spout opening edge via a breakable weakening portion. A closed body that closes the spout and a plug that is provided on the lid body and integrally connects the lid body and the closed body are provided, and the lid body and the closed body are in an open state. A rotation stop portion for suppressing the rotation of the closed body around the unplugging shaft of the unplugging body with respect to the lid body is provided.

In the hinge cap of one aspect of the present invention, the obstructed body connected to the lid body via the unplugging body is moved upward with the opening operation, that is, the operation of rotating the lid body around the hinge with respect to the cap body. When it is pulled up, the weakened part is broken, the obstructed body is transferred to the lid body, and the spout is opened. Therefore, once the lid is opened, the obstructed body is in a state of being connected to the lid. At this time, since the rotation stop portion is provided on the lid body and the closure body, the rotation of the closure body around the unplugging shaft with respect to the lid body in the opened state is suppressed by the action of the rotation stop portion. As a result, there is no possibility that the obstructed body interferes with the peripheral portion of the spout and the lid body cannot be closed, and usability when closing the lid body can be improved.

In the hinge cap of one aspect of the present invention, the rotation stop portion has a lid side engaging portion formed on the lid body and a closed body side engaging portion formed on the closed body, and the said. The lid side engaging portion and the closed body side engaging portion may be engaged with each other to restrict the movement of the plugging shaft in the circumferential direction.

According to this configuration, the lid side engaging portion and the closing body side engaging portion engage with each other to regulate the movement of the plugging shaft in the circumferential direction. Rotation can be reliably suppressed.

In the hinge cap of one aspect of the present invention, the lid-side engaging portion is composed of one or more lid-side ribs formed on the lid, and the closed-side engaging portion is formed on the closed body. It is composed of one or more closed body side ribs, and the one or more lid side ribs and the one or more closed body side ribs are arranged along the circumferential direction of the plugging shaft, and the lid side ribs and the lid side ribs are arranged. One of the closed body side ribs may be arranged so as to sandwich the other.

According to this configuration, the other is sandwiched by one of the lid-side rib and the obstruction-side rib arranged along the circumferential direction of the plug-out shaft. Can be reliably suppressed.

According to one aspect of the present invention, in a hinge cap that can be opened by rotating the lid body, usability when closing the lid body can be improved.

It has a cylindrical pouring cylinder portion 25 and.

The top plate portion 21, the mounting cylinder portion 22, the mounting cylinder portion 23, the fitting cylinder portion 24, and the dispensing cylinder portion 25 are arranged coaxially with the cap shaft O. Further, the cap body 11, the lid 13, and the closed body 15 are integrally formed of a resin material such as linear low density polyethylene (LLDPE) and low density polyethylene (LDPE). The cap body 11, the lid body 13, and the closed body 15 may be made of another resin material.

The spout 11A formed on the top plate portion 21 has a shape corresponding to the closed body 15 shown in FIG. That is, the spout 11A has an egg-shaped anterior portion that is convex toward the front and an egg-shaped extending portion extending rearward from the rear end portion of the anterior portion. The width of the tail in the left-right direction is narrower than the width of the front part in the left-right direction.

As shown in FIG. 1, the mounting cylinder portion 22 is arranged on the radial outer side of the mouth portion 3. On the inner peripheral surface of the lower end portion of the mounting cylinder portion 22, the first mounting protrusion 3A formed on the outer peripheral surface of the mouth portion 3 and projecting outward in the radial direction is locked from below to the inside in the radial direction. A second mounting protrusion 22A is formed so as to project toward.

A first mounting protrusion 23A is formed on the outer peripheral surface of the upper end portion of the mounting cylinder portion 23 so as to project outward in the radial direction.

The fitting cylinder portion 24 sandwiches the upper end portion of the mouth portion 3 together with the mounting cylinder portion 22 in the radial direction. The lower end of the fitting cylinder portion 24 is located above the lower end of the mounting cylinder portion 22.

The dispensing cylinder portion 25 is inclined so as to be radially outward as it goes upward. The front end portion of the dispensing cylinder portion 25 is located above the rear end portion of the dispensing cylinder portion 25. Therefore, the upper end edge of the dispensing cylinder portion 25 is inclined so as to gradually move downward from the front side to the rear side. The upper end edge of the rear end of the pouring cylinder portion 25 is located above the upper end edge of the mounting cylinder portion 23.

The lid 13 has a circular top wall portion 31 in a plan view, a cylindrical peripheral cylinder portion 32 extending downward from the outer peripheral edge of the top wall portion 31, and a radial inner side of the peripheral cylinder portion 32. It has a cylindrical inner cylinder portion 33 extending downward from the top wall portion 31. The top wall portion 31, the peripheral cylinder portion 32, and the inner cylinder portion 33 are formed coaxially with the cap shaft O.

A circular insertion hole 31A is formed in a portion of the top wall portion 31 on the front side of the cap shaft O in a plan view that penetrates the top wall portion 31 in the vertical direction. An unplugging body 16 described later is inserted into the insertion hole 31A. Hereinafter, the central axis of the insertion hole 31A is referred to as a plugging shaft O', the direction rotating around the plugging shaft O'is referred to as a plugging peripheral direction, and the direction intersecting the plugging shaft O'is referred to as a plugging diameter direction.

The top wall portion 31 has a cylindrical upper cylinder portion 34 extending downward from the opening edge portion of the insertion hole 31A and a plan view protruding inward in the plugging radial direction from the lower end portion of the upper cylinder portion 34. It has an annular support portion 35, a cylindrical surrounding cylinder portion 36 extending downward from the inner peripheral edge of the support portion 35, and a lid side rib 37 (cover body side engaging portion). The upper cylinder portion 34, the support portion 35, and the surrounding cylinder portion 36 are formed coaxially with the plugging shaft O'. The lid side rib 37 will be described in detail later.

The front end portion of the upper cylinder portion 34 is integrally connected to the front end portion of the peripheral cylinder portion 32. The surrounding cylinder portion 36 surrounds the outer cylinder portion 53, which will be described later, from the outside, and has a C-shaped shape that opens toward the front in a plan view. As a result, it is possible to prevent the surrounding cylinder portion 36 from interfering with the front end portion of the inner cylinder portion 33.

A second mounting protrusion 32A is formed on the inner peripheral surface of the lower end of the peripheral cylinder portion 32 so as to project outward in the radial direction and engage with the first mounting protrusion 23A of the mounting cylinder portion 23 from below. ing. Further, a knob portion 32B protruding forward is formed at the front end portion of the lower end portion of the peripheral cylinder portion 32. The lower end of the rear end of the peripheral cylinder 32 is connected to the upper end of the mounting cylinder 22 via a hinge 12. As a result, the front end portion of the peripheral cylinder portion 32 is more likely to be elastically deformed in the radial direction as compared with other portions, and when the lid 13 is rotated around the hinge 12 with respect to the cap body 11, the peripheral cylinder portion At the front end portion of 32, the locked state between the second mounting protrusion 32A and the first mounting protrusion 23A is easily released.

The inner cylinder portion 33 is arranged radially inside the dispensing cylinder portion 25, and the lower end portion of the inner cylinder portion 33 is in contact with the inner peripheral surface of the dispensing cylinder portion 25. Further, the front end portion of the inner cylinder portion 33 is located above the rear end portion of the pouring cylinder portion 25. Therefore, the lower end edge of the inner cylinder portion 33 is gradually inclined downward from the front side to the rear side. The front end portion of the inner cylinder portion 33 is connected to the front end portion of the support portion 35.

Similar to the spout 11A, the obstruction body 15 has an oval-shaped obstruction plate 41 that is long in the front-rear direction in a plan view, and a cylindrical strut 42 that protrudes upward from the front end portion of the obstruction plate 41. It has a rib 43 on the closed body side (engaged portion on the closed body side). The strut portion 42 is formed coaxially with the unplugging shaft O'. The closed body side rib 43 will be described in detail later.

An annular seal piece 44 projecting downward is formed on the lower surface of the peripheral edge portion of the blocking plate portion 41. The seal piece 44 is formed over the entire circumference of the closing plate portion 41, and is formed so as to extend radially outward as it goes downward. That is, the seal piece 44 is formed so as to project diagonally downward toward the outside in the radial direction. After opening the seal piece 44, when the lid 13 is opened around the hinge 12, the seal piece 44 comes into contact with the opening edge of the spout 11A from above and elastically deforms so as to be upside down with the upper end as a base point. This makes it possible to seal the opening edge of the spout 11A.

In the portion of the closing plate portion 41 where the strut portion 42 is formed, a recess 41A is formed which penetrates the closing plate portion 41 in the vertical direction and is recessed toward the top of the strut portion 42. At the upper end of the support column 42, a cylindrical outer cylinder portion 53 extending upward and a cylindrical shaft portion 54 extending upward inside the outer cylinder portion 53 are formed. ing. The outer cylinder portion 53 and the shaft portion 54 are formed coaxially with the unplugging shaft O'.

On the inner peripheral surface of the outer cylinder portion 53, two obstructing body locking recesses 53A recessed outward in the radial direction of the plug are formed at intervals in the vertical direction. The obstructing body locking recess 53A is connected to a first inclined surface that gradually inclines outward in the radial direction of unplugging from the upper end edge toward the lower end, and is connected to the lower end of the first inclined surface, and gradually inward in the radial direction of unplugging as it goes downward. It has a second inclined surface that inclines toward. Here, the angle formed by the unplugging shaft O'and the first inclined surface is larger than the angle formed by the unplugging shaft O'and the second inclined surface. The upper end edge of the outer cylinder portion 53 is substantially flush with the upper surface of the support portion 35. The portion of the outer cylinder portion 53 excluding the front end portion is surrounded by the surrounding cylinder portion 36 from the outside in the plugging radial direction.

The upper end portion of the shaft portion 54 is formed to have a smaller diameter than the lower end portion of the shaft portion 54. Further, the upper end of the shaft portion 54 is located above the closed body locking recess 53A on the upper side of the outer cylinder portion 53 and below the upper end of the outer cylinder portion 53.

The lid 13 and the closed body 15 are provided with a rotation stop portion 40 for suppressing the rotation of the closed body 15 in the unplugging circumferential direction (around the plugging shaft O') with respect to the closed body 13 in the opened state. In the present embodiment, the rotation stopper 40 has one lid-side rib 37 formed on the lid 13, and two closure-side ribs 43 formed on the closure 15. Each of the lid side rib 37 and the closed body side rib 43 has a plate-like shape. The lid-side rib 37 and the closed-body-side rib 43 engage with each other to restrict the movement of the plugging shaft O'in the circumferential direction.

In the case of the present embodiment, as shown in FIG. 2, one lid-side rib 37 and two obstruction-side ribs 43 are arranged along the peripheral direction of unplugging, and two obstruction-side ribs 43 are one lid-side rib. It is arranged so as to sandwich the 37. In the case of the present embodiment, the two closed body side ribs 43 and the one lid side rib 37 are in contact with each other, but may be separated from each other.

As shown in FIGS. 1 and 2, the lid side rib 37 extends downward from the lower surface of the support portion 35, and extends from the outer peripheral surface of the surrounding cylinder portion 36 toward the hinge 12 side on the outer side in the plugging radial direction. is doing. The rear end surface of the lid-side rib 37 is located on substantially the same surface as the outer peripheral surface of the upper cylinder portion 34. The lower surface of the lid-side rib 37 is located on substantially the same surface as the lower end surface of the surrounding cylinder portion 36.

The rib 43 on the closed body side extends from the outer peripheral surface of the outer cylinder portion 53 toward the hinge 12 side on the outer side in the radial direction of the plugging. The rib 43 on the closed body side has different dimensions in the height direction between the portion near the outer peripheral surface of the outer cylinder portion 53 and the portion far from the outer peripheral surface of the outer cylinder portion 53. Specifically, the rib 43 on the closed body side is from the lower side to the hinge 12 side of the lower end of the surrounding cylinder portion 36 so as not to interfere with the surrounding cylinder portion 36 of the lid 13 at the portion near the outer peripheral surface of the outer cylinder portion 53. In the portion far from the outer peripheral surface of the outer cylinder portion 53, on the hinge 12 side of the surrounding cylinder portion 36, it extends toward the hinge 12 side so as to face the lid side rib 37. ..

As shown in FIG. 2, in the present embodiment, the length of the closed body side rib 43 in the front-rear direction is slightly longer than the length of the lid side rib 37 in the front-rear direction. That is, the rear end portion of the closed body side rib 43 is located closer to the hinge 12 than the rear end portion of the lid body side rib 37. The length of the rib 43 on the closed body side in the front-rear direction and the length of the rib 37 on the lid side in the front-rear direction may be the same, or conversely to the present embodiment, the length of the rib 37 on the lid side in the front-rear direction. The length may be longer than the length of the closed body side rib 43 in the anteroposterior direction. However, the length of the rib 43 on the closed body side is preferably short as long as the rotation of the closed body 15 around the plugging shaft O'can be suppressed. If the rib 43 on the closed body side is too long, the closed body 15 is less likely to be elastically deformed, and the weakened portion 14 is less likely to be broken.

The unplugging body 16 has a circular head portion 51 in a plan view, and a cylindrical leg tube portion 52 extending downward from the central portion of the head portion 51. The head portion 51 and the leg tube portion 52 are formed coaxially with the unplugging shaft O'. The unplugging body 16 may be made of a material harder than the cap body 11, the lid 13 and the closing body 15, such as polyethylene terephthalate (PET), polyacetal (POM), polypropylene (PP), etc. The constituent material of 16 is not particularly limited, and may be another resin material.

The head portion 51 is arranged above the support portion 35 so as to be separated from the support portion 35, and the upper surface of the head portion 51 is located substantially on the same surface as the upper surface of the top wall portion 31. That is, the lower surface of the head portion 51 and the upper surface of the support portion 35 are not in contact with each other, and a gap is provided between the head portion 51 and the support portion 35.

The leg cylinder portion 52 is fitted between the outer cylinder portion 53 and the shaft portion 54 of the closing body 15, and is sandwiched between the outer cylinder portion 53 and the shaft portion 54 in the plugging diameter direction. On the outer peripheral surface of the leg tube portion 52, two closed body locking protrusions 52A, which project outward in the radial direction of the plug and are individually locked to the closed body locking recess 53A, are formed at intervals in the vertical direction. Has been done. The closed body locking protrusion 52A is locked to the closed body locking recess 53A from below.

Similar to the closed body locking recess 53A, the closed body locking protrusion 52A is formed on a first inclined surface that gradually inclines downward from the upper end edge toward the outer side in the radial direction of unplugging, and on the lower end of the first inclined surface. It has a second inclined surface that is continuous and is gradually inclined inward in the radial direction of unplugging as it goes downward. Here, the angle formed by the unplugging shaft O'and the first inclined surface is larger than the angle formed by the unplugging shaft O'and the second inclined surface. Further, the inner diameter of the upper end portion of the leg cylinder portion 52 is smaller than the inner diameter of the lower end portion of the leg cylinder portion 52.

Further, the pull-out strength between the leg cylinder portion 52 of the unplugging body 16 and the outer cylinder portion 53 and the shaft portion 54 of the closing body 15 is larger than the breaking strength of the weakened portion 14. As a result, when the lid 13 is rotated around the hinge 12 with respect to the cap body 11, the leg tube portion 52 of the unplugging body 16 becomes the outer tube portion 53 of the closing body 15 before the weakened portion 14 breaks. It is prevented from coming out from between the shaft portion 54 and the shaft portion 54.

The unplugging body 16 is inserted into the insertion hole 31A with the lid 13 attached to the cap body 11, and the leg tube portion 52 is combined with the outer tube portion 53 and the shaft portion 54 by using a plugging machine (not shown) or the like. It is attached to the lid 13 by driving it between the two. Further, the hinge cap 1 is attached to the mouth portion 3 of the container body 2 by using a stopper (not shown) or the like.

Hereinafter, the usage and operation of the hinge cap 1 having the above configuration will be described.
When the product is unopened, such as during product transportation or product distribution, as shown in FIG. 1, a state in which the closing body 15 connected to the opening edge of the spout 11A via the weakening portion 14 closes the spout 11A. It has become. As a result, the space between the inside and the outside of the container body 2 can be sealed with high airtightness. Therefore, it is possible to suppress the leakage of the contents to the outside and also to prevent the outside air, moisture and the like from entering the container body 2 from the outside.

When opening the container, first, the knob portion 32B of the lid body 13 is pulled up, and the lid body 13 is rotated around the hinge 12 with respect to the cap body 11. At this time, since a gap is provided between the head portion 51 of the plugging body 16 and the support portion 35 of the lid body 13, the plugging body 16 is used until the head portion 51 and the support portion 35 come into contact with each other. Only the lid 13 moves upward without moving. At this time, the upper surface of the top wall portion 31 of the lid 13 moves to a position higher than the upper surface of the head portion 51 of the plugging body 16. That is, the unplugging body 16 is in a state of being moved downward with respect to the lid body 13.

After that, from the time when the lid 13 moves upward to the position where the head portion 51 and the support portion 35 come into contact with each other, the downward movement of the plug 16 with respect to the lid portion 13 is restricted by the support portion 35. As a result, the unplugging body 16 rotates around the hinge 12 with respect to the cap body 11 along with the lid body 13. Further, since the closing body locking protrusion 52A of the leg cylinder portion 52 of the plugging body 16 is locked from below to the closing body locking recess 53A of the outer cylinder portion 53 of the closing body 15, the plugging body 16 As the hinge 12 rotates, an upward force acts on the closed body 15.

This upward force breaks the weakened portion 14, separates the obstructed body 15 from the spouting cylinder portion 25 of the cap body 11, and opens the spout 11A, as shown in FIG. At this time, the weakened portion 14 is sequentially broken from the front end portion to the rear end portion. Here, the breaking strength of the weakened portion 14 connecting the closing body 15 and the dispensing cylinder portion 25 of the cap body 11 is the same as that of the leg cylinder portion 52 of the unplugging body 16 and the outer cylinder portion 53 and the shaft portion 54 of the closing body 15. Since it is smaller than the pull-out strength between the two, when the lid 13 is rotated around the hinge 12 with respect to the cap body 11, the leg tube portion 52 of the plugging body 16 is closed before the weakened portion 14 breaks. It is prevented from coming out from between the outer cylinder portion 53 and the shaft portion 54 of 15.

Here, the closed body 15 separated from the fitting cylinder portion 24 of the cap main body 11 is held by the lid body 13 by the unplugging body 16. In other words, the closing body 15 moves from the cap body 11 to the lid 13 in a form of being connected to the lid 13 via the unplugging body 16.

After that, the contents in the container body 2 are appropriately poured out from the spout 11A by tilting the container body 2 or the like. After pouring out the contents, the lid 13 is rotated around the hinge 12 to close the spout 11A, so that the spout 11A can be closed again by the obstructed body 15 transferred to the lid 13. Further, at this time, the seal piece 44 of the closing body 15 can be elastically deformed so as to be turned upside down, and the lid 13 can be closed while sealing the opening edge of the spout 11A by using the seal piece 44. can.

In this way, according to the hinge cap 1 of the present embodiment, the container body 2 can be stored in a state where the inside of the container body 2 is appropriately sealed, and the inside of the top wall portion 31 of the lid body 13. It is possible to prevent the contents from entering the space surrounded by the tubular portion 33, the closed body 15, and the like, and prevent the contents from getting dirty.

As described above, in the hinge cap 1 having a structure in which the lid body 13 and the closing body 15 are connected via the unplugging body 16, the closing body 15 and the lid body 13 are connected before the weakened portion 14 is broken at the time of opening. The vertical movement of the obstructed body 15 with respect to the lid 13 is restricted, while the rotation of the obstructed body 15 with respect to the lid 13 around the unplugging axis O'is restricted. do not have. Therefore, in the opened state, the obstructed body 15 may rotate around the unplugging shaft O'.

When the obstruction body 15 rotates with the lid body 13 open, for example, when the obstruction body 15 has an elongated shape as in the present embodiment, depending on the degree of rotation, when the lid body 13 is to be closed. , The closing body 15 may interfere with the dispensing cylinder portion 25 of the cap main body 11 and the lid body 13 may not be closed. In that case, in order to close the lid 13, the user needs to rotate the closing body 15 to return it to the original position, which causes a problem that the usability at the time of the closing operation is lowered.

In response to this problem, in the hinge cap 1 of the present embodiment, the lid 13 and the closed body 15 have a rotation stop portion that suppresses the rotation of the closed body 15 around the unplugging shaft O'with respect to the lid 13 in the opened state. Since the 40 is provided, the rotation of the closed body 15 with respect to the lid 13 is suppressed by the action of the rotation stop portion 40. As a result, there is no possibility that the lid 13 will not be closed due to the obstruction body 15 interfering with the dispensing cylinder portion 25, and the usability when closing the lid 13 can be improved.

Further, for example, when the closing body 15 rotates a little so as not to interfere with the dispensing cylinder portion 25, it is possible to close the lid body 13, but even in that case, there is a possibility as follows. That is, when the lid is closed after opening the container, if the obstructed body rotates and deviates from the position before opening, the obstructed body has a positional relationship deviated from the shape of the spout. In this case, since the obstructed body cannot completely block the spout, for example, when the container is laid on its side or the container is shaken to stir the contents liquid, the space between the lid and the obstructed body is created. When the content liquid enters and the lid is opened again, the content liquid may flow out or scatter from the space, and the hinge cap or the container may become dirty. On the other hand, according to the hinge cap 1 of the present embodiment, even a slight rotation of the closing body 15 is suppressed, and the closing body 15 can completely close the spout 11A when the lid is closed after opening. The above problem can be solved.

In particular, in the case of the present embodiment, the rotation stop portion 40 has one lid side rib 37 and two closed body side ribs 43, and the lid body side rib 37 and the closed body side rib 43 are arranged along the plugging peripheral direction. Two closed body side ribs 43 are arranged so as to sandwich one lid side rib 37. Therefore, with a simple configuration, it is possible to reliably suppress the rotation of the closing body 15 around the plugging shaft O'with respect to the lid body 13. The rib 37 on the lid side and the rib 43 on the closed body side may not be completely in contact with each other, and a slight gap may be left between the rib 37 on the lid body side and the rib 43 on the closed body side. When there is a gap between the lid side rib 37 and the obstruction body side rib 43, a slight rotation of the obstruction body 15 to a position where the lid body side rib 37 and the obstruction body side rib 43 abut is allowed, but the obstruction body 15 is allowed. It is sufficient that the rotation does not interfere with the dispensing cylinder portion 25. Even in this case, it is desirable that the rotation is such that the outflow of the above-mentioned content liquid hardly causes a problem. According to this configuration, it is possible to secure a manufacturing tolerance of the rotation stop portion 40.

Further, in the case of the present embodiment, when the lid 13 is rotated around the hinge 12 with respect to the cap body 11, the unplugging body 16, particularly the leg tube portion 52, is suppressed from being deformed, and the unplugging body 16 is prevented from being deformed. It is difficult to release the locked state between the closed body locking protrusion 52A and the closed body locking recess 53A of the closed body 15. Therefore, the spout 11A can be opened more reliably by the operation of rotating the lid 13 around the hinge 12 with respect to the cap body 11, and the operability at the time of opening can be improved.

Further, in the case of the present embodiment, the leg cylinder portion 52 of the plugging body 16 is sandwiched between the outer cylinder portion 53 and the shaft portion 54, and elastic deformation of the leg cylinder portion 52 in the plugging diameter direction is suppressed. It is possible to more reliably prevent the unplugging body 16 from coming out of the closing body 15 when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11. Further, since the head portion 51 of the plugging body 16 is supported from below by the support portion 35 of the lid body 13, the lid body 13 is pulled up when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11. The force can be smoothly transmitted to the head portion 51. As a result, the weakened portion 14 can be broken more reliably.

Further, in the case of the present embodiment, since the plug 16 moves downward with respect to the lid 13 in the insertion hole 31A with the opening operation, the user can see that the upper surface of the plug 16 is on the upper surface of the lid 13. From the fact that it is in the lowered position, it can be easily determined that the hinge cap 1 has already been opened.

[Second Embodiment]
Hereinafter, the second embodiment of the present invention will be described with reference to FIGS. 4 and 5.
The basic configuration of the hinge cap of the second embodiment is the same as that of the first embodiment, and the configuration of the rotation stop portion is different from that of the first embodiment. Therefore, in the present embodiment, the description of the basic configuration will be omitted.
FIG. 4 is a view showing the hinge cap 5 of the present embodiment, and is a vertical sectional view of the hinge cap 5 in the closed state. FIG. 5 is a plan view of the lid body in the opened state.
In FIGS. 4 and 5, the same components as those in the drawings used in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIGS. 4 and 5, in the hinge cap 5 of the present embodiment, the rotation stop portion 60 is formed on the lid body side uneven portion 62 (cover body side engaging portion) formed on the lid body 61 and the closure body 63. It has a formed closed body side uneven portion 64 (closed body side engaging portion). The concavo-convex portion 62 on the lid side and the concavo-convex portion 64 on the closed body side engage with each other to restrict the movement of the plugging shaft O'in the circumferential direction. In the case of the present embodiment, each of the lid-side uneven portion 62 and the closed body-side uneven portion 64 is formed in a so-called knurled shape.

In the case of the present embodiment, specifically, in the lid-side uneven portion 62, the lid-side rib 66 extends in the vertical direction, and the cross-sectional shape orthogonal to the vertical direction is a triangle pointed inward in the plugging radial direction. It is composed of ridges of shape. Between the two adjacent lid-side ribs 66, a groove portion 67 having a V-shaped cross-sectional shape orthogonal to the vertical direction is formed. The lid-side rib 66 is formed so as to extend in the vertical direction along the inner peripheral surface of the surrounding cylinder portion 36 of the lid.

The concavo-convex portion 64 on the closed body side has a configuration of being fitted to the concavo-convex portion 62 on the lid body side. That is, in the closed body side uneven portion 64, the closed body side rib 68 extends in the vertical direction and is composed of triangular ridges having a cross-sectional shape orthogonal to the vertical direction and sharpened toward the outside in the plugging radial direction. .. Between the two adjacent ribs on the closed body side, a groove portion 69 having a V-shaped cross-sectional shape orthogonal to the vertical direction is formed. The closed body side rib 68 is formed so as to extend in the vertical direction along the outer peripheral surface of the outer cylinder portion 53. Therefore, the lid side rib 66 of the lid side uneven portion 62 and the groove portion 69 of the closed body side uneven portion 64 are fitted to each other, and the groove portion 67 of the lid side uneven portion 62 and the closed body side rib 68 of the closed body side uneven portion 64 are mutually fitted. Fit.

The cross-sectional shape of each of the uneven portions 62 and 64 does not necessarily have to be triangular, and may be, for example, a quadrangular shape. Further, each of the uneven portions 62 and 64 does not necessarily have to be composed of ridges and grooves extending in the vertical direction, and may be composed of, for example, protrusions and holes.
Other configurations of the hinge cap 5 are the same as those of the hinge cap 1 of the first embodiment.

Also in the hinge cap 5 of the present embodiment, since the rotation of the closing body 63 with respect to the lid 61 is suppressed by the action of the rotation stop portion 60, there is no possibility that the closing body 63 interferes with the dispensing cylinder portion 25, and the lid body The same effect as that of the first embodiment can be obtained, such that the usability when closing the 61 can be improved.

Further, in the case of the present embodiment, the rotation stop portion 60 has a lid-side uneven portion 62 and a closed body-side uneven portion 64 arranged along the plugging diameter direction, and the lid-side uneven portion 62 and the closed body-side uneven portion 64. Are fitted to each other. Therefore, with a simple configuration, it is possible to reliably suppress the rotation of the closing body 63 around the plugging shaft with respect to the lid body 61.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the rotation stop portion 40 of the first embodiment has a configuration in which two closure-side ribs 43 sandwich one lid-side rib 37, but contrary to this configuration, two lid-side ribs have one. It may have a structure that sandwiches one closed body side rib. Further, for example, when the obstructed body has an asymmetrical shape and the obstructed body easily interferes with the pouring cylinder portion when rotated in a specific direction, the configuration is such that two ribs sandwich one rib. It may not be provided, and a rib that suppresses rotation on the side where the obstructed body easily interferes with the dispensing cylinder portion may be provided on only one side.

Further, in the above embodiment, the unplugging body 16 and the lids 13 and 61 are formed as separate bodies, and the unplugging body 16 is attached to the insertion hole 31A of the lids 13 and 61. The body may have a function of connecting the obstructed body to the lid, and may be integrally formed with the lid instead of the above configuration.

Further, when the plugging body and the lid body are formed as separate bodies, in the above embodiment, the plugging body 16 and the support portions 35 of the lid bodies 13 and 61 are not in contact with each other in the closed state, and the lid body 13 is not in contact with each other. , 61 was slightly rotated around the hinge 12, and then the plug 16 and the support portion 35 came into contact with each other, and the downward movement of the plug 16 was restricted. The structure may be such that the unplugging body and the support portion are in contact with each other from the state, and the downward movement of the unplugging body is restricted. Further, the lids 13 and 61 do not necessarily have to be provided with the insertion holes 31A. Further, any form is used as long as the engaging portion on the lid side and the engaging portion on the closed body side are engaged when the lid is closed, the closed body side is broken at the time of opening the lid, and the closed body side is transferred to the lid body side. May be good.

Further, the shape of the spout 11A is not limited to an oval shape that is long in the front-rear direction, and may be another shape such as a perfect circle shape or a polygonal shape. The cap body 11 has a ridged cylinder shape and has a mounting cylinder portion 22 that surrounds the mouth portion 3 of the container body 2 from the outside in the radial direction, but if it is mounted on the mouth portion 3 of the container body 2. The shape is not limited to the ridged cylinder, but may have other shapes such as a plate. Further, although the strut portion 42 is formed at a position shifted forward from the cap shaft O, it may be formed at another position such as forming coaxially with the cap shaft O. However, when the lids 13 and 61 are rotated around the hinge 12 with respect to the cap body 11, the weakened portion 14 is broken in order from the front end portion, so that the strut portion 42 is displaced forward from the cap shaft O. It is preferably formed at the position.

Further, the specific description of the number, shape, arrangement, constituent materials and the like of each component constituting the hinge cap is not limited to the above embodiment, and can be appropriately changed. Further, the shape of the hinge cap and the container body is not limited to the cylindrical shape, and may have other shapes such as an elliptical shape and a polygonal tubular shape.
