Description

The present invention relates to a hinge cap.

BACKGROUND ART Hinge caps that can be opened only by opening the lid without having to pull up a pull ring after opening the lid have been known. For example, Patent Document 1 listed below discloses a cap including a lid and a cap base having a top wall to which a separation piece is connected via a weakened portion. According to this cap, when the lid is first opened, the weakened portion is broken and the separation piece moves toward the lid, thereby opening the portion where the separation piece was connected and opening the container.

Japanese Patent Application Publication No. 2015-34012

When using this type of hinged cap, the separation piece remains connected to the lid once the container is opened. However, in the case of a cap having a structure in which a separation piece is fitted into a cylindrical portion of a lid body, as in Patent Document 1, the separation piece may rotate about the axis of the cylindrical portion. However, if the separation piece rotates with the lid open, depending on the shape of the separation piece and the degree of rotation, the separation piece may interfere with the peripheral portion of the spout, making it impossible to close the lid. In that case, in order to close the lid, the user must rotate the separation piece and return it to its original position, which reduces usability during the closing operation. Therefore, it is desired to improve usability when closing the lid in a hinge cap configured such that the closing body of the spout is transferred to the lid.

One aspect of the present invention has been made to solve the above problems, and is to improve 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 allows for

In order to achieve the above object, a hinged cap according to one aspect of the present invention includes a cap body that is attached to the mouth of a container body in which contents are stored, and is formed with a spout for pouring out the contents. , a capped cylindrical lid body rotatably connected to the cap body around a hinge and covering the spout so as to be openable and closable; and a lid body connected to the opening edge of the spout via a breakable weakened part. a closure body that closes the spout with a stopper, and a plug removal body that is provided on the lid body and connects the lid body and the closure body together; A rotation stopper is provided for suppressing rotation of the closure body about the closure axis of the closure body with respect to the lid body.

In the hinged cap of one aspect of the present invention, when the opening operation is performed, that is, the operation of rotating the lid body around the hinge with respect to the cap body, the closing body connected to the lid body through the plug removal body moves upward. When the lid is pulled up, the weakened portion is broken, the closure body is transferred to the lid body, and the spout is opened. Therefore, once the lid is opened, the closure body is connected to the lid. At this time, since the above-mentioned rotation stopper is provided on the lid and the closure, the rotation of the closure around the stopper axis with respect to the open lid is suppressed by the action of the rotation stop. This eliminates the possibility that the closure body will interfere with the peripheral portion of the spout and prevent the lid from closing, thereby improving usability when closing the lid.

In the hinge cap according to one aspect of the present invention, the rotation stopper includes a lid-side engaging portion formed on the lid and a closing body-side engaging portion formed on the closing body, The lid-side engaging portion and the closure body-side engaging portion may restrict movement of the plug shaft in the circumferential direction by engaging with each other.

According to this configuration, the lid body side engaging part and the closure body side engaging part restrict movement of the cap removal shaft in the circumferential direction by engaging with each other. Rotation can be reliably suppressed.

In the hinge cap according to one aspect of the present invention, the lid-side engaging portion includes one or more lid-side ribs formed on the lid, and the closing body-side engaging portion is formed on the closing body. The one or more lid side ribs and the one or more lid side ribs are arranged along the circumferential direction of the plug removal shaft, and the lid side ribs and the one or more lid side ribs are arranged along the circumferential direction of the plug removal shaft. One of the closing body side ribs may be arranged to sandwich the other.

According to this configuration, since the other is sandwiched between one of the lid side ribs and the closure body side ribs arranged along the circumferential direction of the cap removal shaft, rotation of the closure body around the closure shaft with respect to the lid body is facilitated by a simple configuration. can be reliably suppressed.

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

The top plate part 21, the mounting cylinder part 22, the attachment cylinder part 23, the fitting cylinder part 24, and the pouring cylinder part 25 are arranged coaxially with the cap axis O. Further, the cap body 11, the lid body 13, and the closure body 15 are integrally formed of a resin material such as linear low-density polyethylene (LLDPE) or low-density polyethylene (LDPE). Note that the cap body 11, the lid body 13, and the closure body 15 may be formed from other resin materials.

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

As shown in FIG. 1, the mounting cylinder portion 22 is disposed on the outside of the mouth portion 3 in the radial direction. A first mounting protrusion 3A formed on the outer circumferential surface of the mouth portion 3 and protruding radially outward is engaged with the inner circumferential surface of the lower end of the mounting cylinder portion 22 from below, A second mounting protrusion 22A is formed that protrudes toward.

A first mounting protrusion 23A that projects radially outward is formed on the outer peripheral surface of the upper end of the mounting cylinder 23.

The fitting cylinder part 24 and the mounting cylinder part 22 sandwich the upper end of the mouth part 3 in the radial direction. Note that the lower end of the fitting cylinder part 24 is located above the lower end of the mounting cylinder part 22.

The pouring cylinder portion 25 is inclined radially outward as it goes upward. The front end of the spouting cylinder part 25 is located above the rear end of the spouting cylinder part 25. Therefore, the upper end edge of the spouting cylinder part 25 is sloped gradually downward from the front side toward the rear side. Note that the upper end edge of the rear end of the pouring cylinder part 25 is located above the upper end edge of the mounting cylinder part 23.

The lid body 13 includes a top wall portion 31 that is circular in plan view, a cylindrical circumferential tube portion 32 that extends downward from the outer peripheral edge of the top wall portion 31, and a radially inner side of the circumferential tube portion 32. It has a cylindrical inner cylinder part 33 extending downward from the top wall part 31. The top wall portion 31, the circumferential tube portion 32, and the inner tube portion 33 are formed coaxially with the cap axis O.

An insertion hole 31A, which is circular in plan view and passes through the top wall 31 in the vertical direction, is formed in a portion of the top wall 31 on the front side of the cap axis O. A plug removal body 16, which will be described later, is inserted into the insertion hole 31A. Hereinafter, the central axis of the insertion hole 31A will be referred to as the plug-removal axis O', the direction of rotation around the plug-removal axis O' will be referred to as the plug-removal circumferential direction, and the direction intersecting the plug-removal axis O' will be referred to as the plug-removal radial direction.

In plan view, the top wall portion 31 includes a cylindrical upper tube portion 34 that extends downward from the opening edge of the insertion hole 31A, and a cylindrical upper tube portion 34 that protrudes inward in the plug removal radial direction from the lower end of the upper tube portion 34. It has an annular support portion 35, a cylindrical surrounding tube portion 36 extending downward from the inner peripheral edge of the support portion 35, and a lid side rib 37 (lid side engaging portion). The upper cylinder part 34, the support part 35, and the surrounding cylinder part 36 are formed coaxially with the cap removal axis O'. The lid side rib 37 will be explained in detail later.

The front end portion of the upper cylinder portion 34 is integrally continuous with the front end portion of the circumferential cylinder portion 32. The surrounding cylinder part 36 surrounds an outer cylinder part 53, which will be described later, from the outside, and has a C-shape that opens forward in plan view. This prevents the surrounding cylindrical portion 36 from interfering with the front end portion of the inner cylindrical portion 33.

A second mounting protrusion 32A is formed on the inner peripheral surface of the lower end of the circumferential cylindrical portion 32 and protrudes radially outward and engages with the first mounting protrusion 23A of the mounting cylindrical portion 23 from below. ing. Furthermore, a knob portion 32B that protrudes forward is formed at the front end of the lower end portion of the circumferential tube portion 32. A lower end portion of the rear end portion of the circumferential tube portion 32 is connected to an upper end of the mounting tube portion 22 via the hinge 12. As a result, the front end portion of the circumferential tube portion 32 is more easily elastically deformed in the radial direction than other portions, and when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, the circumferential tube portion The locked state between the second attachment protrusion 32A and the first attachment protrusion 23A at the front end of the second attachment protrusion 32 is easily released.

The inner cylinder part 33 is arranged radially inward than the spout cylinder part 25 , and the lower end of the inner cylinder part 33 is in contact with the inner circumferential surface of the spout cylinder part 25 . Further, the front end portion of the inner cylinder portion 33 is located above the rear end portion of the spout cylinder portion 25. Therefore, the lower end edge of the inner cylindrical portion 33 is gradually inclined downward as it goes from the front side to the rear side. Note that a front end portion of the inner cylinder portion 33 is continuous with a front end portion of the support portion 35 .

The closure body 15 includes a closure plate portion 41 that is elongated in the front-rear direction when viewed from above in the same manner as the spout 11A, and a cylindrical support portion 42 that projects upward from the front end of the closure plate portion 41. It has a closure body side rib 43 (closure body side engaging portion). The support column 42 is formed coaxially with the cork removal axis O'. The closure body side rib 43 will be explained in detail later.

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

A concave portion 41A that vertically penetrates the closure plate portion 41 and is recessed toward the top of the column portion 42 is formed in the portion of the closure plate portion 41 where the support column portion 42 is formed. A cylindrical outer tube portion 53 extending upward and a columnar shaft portion 54 extending upward inside the outer tube portion 53 are formed at the upper end portion of the support column 42. ing. The outer cylinder part 53 and the shaft part 54 are formed coaxially with the plug removal axis O'.

Two obturator locking recesses 53A recessed toward the outside in the radial direction of plugging are formed on the inner peripheral surface of the outer cylinder portion 53 at intervals in the vertical direction. The obturator locking recess 53A has a first inclined surface that slopes gradually outward in the radial direction of the plug as it goes downward from the upper end edge, and a first inclined surface that is connected to the lower end of the first slope and gradually slopes inward in the radial direction of the plug as it goes downward. and a second inclined surface inclined toward. Here, the angle between the cap removal axis O' and the first inclined surface is larger than the angle between the cap removal axis O' and the second inclined surface. The upper edge of the outer cylinder portion 53 is substantially flush with the upper surface of the support portion 35 . A portion of the outer cylindrical portion 53 excluding the front end portion is surrounded by the surrounding cylindrical portion 36 from the outside in the plug removal 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 closure 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 closure 15 are provided with a rotation stopper 40 that suppresses rotation of the closure 15 in the circumferential direction of cap removal (around the cap removal axis O') with respect to the lid 13 in an open state. In this embodiment, the rotation stopper 40 includes 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 body side rib 37 and the closure body side rib 43 has a plate-like shape. The lid body side rib 37 and the closure body side rib 43 mutually restrict movement of the cap removal shaft O' in the circumferential direction by engaging with each other.

In the case of this embodiment, as shown in FIG. 2, one lid-side rib 37 and two closure-side ribs 43 are arranged along the circumferential direction of the plug, and the two closure-side ribs 43 form one lid-side rib. 37 is placed between them. In the case of this embodiment, the two closure body side ribs 43 and one lid body side rib 37 are in contact with each other, but they may be spaced apart.

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 outside in the plug removal radial direction. are doing. The rear end surface of the lid side rib 37 is located on substantially the same plane as the outer circumferential surface of the upper cylinder part 34. The lower surface of the lid-side rib 37 is located substantially on the same plane as the lower end surface of the surrounding cylinder part 36.

The closure body side rib 43 extends from the outer circumferential surface of the outer cylinder portion 53 toward the hinge 12 side on the outside in the plug removal radial direction. The closure body side rib 43 has different dimensions in the height direction between a portion close to the outer peripheral surface of the outer cylinder portion 53 and a portion far from the outer peripheral surface of the outer cylinder portion 53. Specifically, in a portion close to the outer peripheral surface of the outer cylinder part 53, the closure body side rib 43 extends from below the lower end of the surrounding cylinder part 36 to the hinge 12 side so as not to interfere with the surrounding cylinder part 36 of the lid body 13. A portion farther from the outer circumferential surface of the outer cylindrical portion 53, on the side closer to the hinge 12 than the surrounding cylindrical portion 36, extends toward the hinge 12 side so as to face the lid side rib 37. .

As shown in FIG. 2, in this embodiment, the length of the closure body-side rib 43 in the front-rear direction is slightly longer than the length of the lid body-side rib 37 in the front-rear direction. That is, the rear end portion of the closure body side rib 43 is located closer to the hinge 12 than the rear end portion of the lid body side rib 37 . Note that the length of the closure body side rib 43 in the front and rear direction may be the same as the length of the lid body side rib 37 in the front and rear direction, or contrary to this embodiment, the length of the lid body side rib 37 in the front and back direction may be the same. The length may be longer than the length of the obturator side rib 43 in the front-rear direction. However, the length of the closure body side rib 43 is desirably short as long as rotation of the closure body 15 around the plug removal axis O' can be suppressed. If the closing body side rib 43 is too long, the closing body 15 will be difficult to elastically deform, and the weakened portion 14 will be difficult to break.

The plug removal body 16 has a head portion 51 that is circular in plan view, and a cylindrical leg portion 52 that extends downward from the center of the head portion 51. The head portion 51 and the leg cylinder portion 52 are formed coaxially with the cap removal axis O'. The plug body 16 may be made of a material harder than the cap body 11, the lid body 13, and the closure body 15, such as polyethylene terephthalate (PET), polyacetal (POM), or polypropylene (PP). The constituent material of 16 is not particularly limited, and may be other resin materials.

The head portion 51 is disposed above the support portion 35 and spaced apart from the support portion 35 , and the upper surface of the head portion 51 is located approximately on the same plane as the upper surface of the top wall portion 31 . That is, the lower surface of the head section 51 and the upper surface of the support section 35 are not in contact with each other, and a gap is provided between the head section 51 and the support section 35.

The leg cylinder part 52 is fitted between the outer cylinder part 53 and the shaft part 54 of the closure body 15, and is sandwiched between the outer cylinder part 53 and the shaft part 54 in the plug removal radial direction. Two obturator locking protrusions 52A are formed at an interval in the vertical direction on the outer circumferential surface of the leg cylinder portion 52, which protrude outward in the plug removal radial direction and are individually locked with the obturator locking recess 53A. has been done. The closing body locking protrusion 52A locks into the closing body locking recess 53A from below.

Similar to the closure body locking recess 53A, the closure body locking protrusion 52A has a first slope that gradually slopes outward in the plug removal radial direction as it goes downward from the upper end edge, and a lower end of the first slope. and a second inclined surface that is continuous and slopes gradually inward in the radial direction of the plug as it goes downward. Here, the angle between the cap removal axis O' and the first inclined surface is larger than the angle between the cap removal axis O' and the second inclined surface. Further, the inner diameter of the upper end portion of the leg tube portion 52 is smaller than the inner diameter of the lower end portion of the leg tube portion 52.

Further, the pull-out strength between the leg tube portion 52 of the plug removal body 16 and the outer tube portion 53 and shaft portion 54 of the closure body 15 is greater than the breaking strength of the weakened portion 14 . As a result, when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, the leg cylinder part 52 of the plug removal body 16 connects with the outer cylinder part 53 of the closure body 15 before the weakened part 14 breaks. It is suppressed from slipping out from between the shaft portion 54.

The cap removal body 16 is inserted into the insertion hole 31A with the lid body 13 attached to the cap body 11, and the leg cylinder part 52 is connected to the outer cylinder part 53 and the shaft part 54 using a capper (not shown) or the like. It is attached to the lid body 13 by driving it in between. Further, the hinge cap 1 is attached to the opening 3 of the container body 2 using a capper (not shown) or the like.

Hereinafter, how to use and function of the hinge cap 1 having the above structure will be explained.
When unopened, such as during product transportation or product distribution, as shown in FIG. 1, a closing body 15 connected to the opening edge of the spout 11A via the weakened portion 14 closes the spout 11A. It becomes. Thereby, the inside and outside of the container body 2 can be sealed with high airtightness. Therefore, it is possible to suppress leakage of the contents to the outside, and it is also possible to suppress outside air, moisture, etc. from entering into the container body 2 from the outside.

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

Thereafter, from the time when the lid 13 moves upward to a position where the head 51 and the support 35 come into contact, the support 35 restricts the downward movement of the plug removal body 16 with respect to the lid 13 . Thereby, the plug removal body 16 rotates around the hinge 12 with respect to the cap body 11 along with the lid body 13. Further, since the closure body locking protrusion 52A of the leg cylinder part 52 of the plug removal body 16 is locked from below to the closure body locking recess 53A of the outer cylinder part 53 of the closure body 15, the closure body 16 is locked. As the closing body 15 rotates around the hinge 12, an upward force is also applied to the closing body 15.

The weakened portion 14 is broken by this upward force, and as shown in FIG. 3, the closing body 15 is separated from the spouting cylinder portion 25 of the cap body 11, and the spout 11A is opened. At this time, the weakened portion 14 is sequentially broken from the front end toward the rear end. Here, the breaking strength of the weakened part 14 connecting the closure body 15 and the spouting cylinder part 25 of the cap main body 11 is the same as that of the leg cylinder part 52 of the plug removal body 16, the outer cylinder part 53 and the shaft part 54 of the closure body 15. When the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, the leg cylinder part 52 of the plug body 16 breaks off before the weakened part 14 breaks. 15 is prevented from slipping out from between the outer cylindrical portion 53 and the shaft portion 54.

Here, the closure body 15 separated from the fitting cylinder portion 24 of the cap body 11 is held on the lid body 13 by the plug removal body 16. In other words, the closure body 15 transitions from the cap body 11 to the lid body 13 in a form connected to the lid body 13 via the plug removal body 16 .

Thereafter, the contents inside 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 spout 11A can be closed again by the closing body 15 transferred to the lid 13 by rotating the lid 13 around the hinge 12 to close the spout 11A. Furthermore, at this time, the seal piece 44 of the closure body 15 can be elastically deformed so as to be turned upside down, and the lid body 13 can be closed while sealing the opening edge of the spout 11A using the seal piece 44. can.

In this way, according to the hinge cap 1 of the present embodiment, it is possible to store the container body 2 in a state where the inside of the container body 2 is properly sealed, and the top wall portion 31 of the lid body 13 and the inside of the container body 2 can be stored. Intrusion of the contents into the space surrounded by the cylindrical portion 33, the closure body 15, etc. is suppressed, and staining can be prevented.

As described above, in the hinge cap 1 having a structure in which the lid 13 and the closure body 15 are connected via the plug removal body 16, the closure body 15 and the closure body 13 are connected to each other before the weakened part 14 breaks when the cap is opened. Since the connection is not released, vertical movement of the closure body 15 with respect to the lid body 13 is restricted, but rotation of the closure body 15 with respect to the lid body 13 around the unplugging axis O' is not restricted. do not have. Therefore, in the lid open state, the closure body 15 may rotate around the plug removal axis O'.

When the closure body 15 rotates with the lid body 13 open, for example, if the closure body 15 has an elongated shape as in this embodiment, depending on the degree of rotation, when the lid body 13 is attempted to close. , there is a possibility that the closing body 15 interferes with the spouting cylinder portion 25 of the cap body 11 and the lid body 13 becomes unable to close. In that case, in order to close the lid 13, the user needs to rotate the closure 15 and return it to its original position, which poses a problem in that usability during the closing operation is reduced.

To solve this problem, in the hinge cap 1 of the present embodiment, the lid body 13 and the closure body 15 have a rotation stopper that suppresses rotation of the closure body 15 around the cap removal axis O' with respect to the lid body 13 in the open state. 40, the rotation of the closure body 15 with respect to the lid body 13 is suppressed by the action of the rotation stop portion 40. This eliminates the possibility that the lid 13 will not close due to the obstruction 15 interfering with the spouting cylinder portion 25, and the usability when closing the lid 13 can be improved.

Further, for example, if the closing body 15 rotates a little to the extent that it does not interfere with the spouting cylinder part 25, it is possible to close the lid body 13, but even in that case, there is a risk as described below. That is, when closing the lid after opening the container, if the closing body rotates and deviates from the position before opening, the closing body will be in a positional relationship that is deviated from the shape of the spout. In this case, the closing body cannot completely block the spout, so if the container is tipped on its side or shaken to stir the contents, the space between the lid and the closing body will be filled. When the liquid contents enter the container and the lid is opened again, there is a risk that the liquid contents may flow out or scatter from the space, staining the hinge cap and the container. On the other hand, according to the hinge cap 1 of the present embodiment, the 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.

Particularly in the case of this embodiment, the rotation stopper 40 has one lid-side rib 37 and two closure-side ribs 43, and the lid-side rib 37 and the closure-side rib 43 are arranged along the circumferential direction of the cap. , two closing body side ribs 43 are arranged so as to sandwich one lid body side rib 37. Therefore, with a simple configuration, it is possible to reliably suppress rotation of the closure body 15 about the plug removal axis O' with respect to the lid body 13. Note that the lid-side rib 37 and the closure-side rib 43 do not need to be in complete contact with each other, and there may be a slight gap between the lid-side rib 37 and the closure-side rib 43. If there is a gap between the lid-side rib 37 and the closure-side rib 43, a slight rotation of the closure 15 until the lid-side rib 37 and the closure-side rib 43 come into contact is allowed; It is sufficient if the rotation is within a range that does not interfere with the spouting cylinder part 25. Even in this case, it is desirable that the rotation be such that the above-mentioned outflow of the content liquid is hardly a problem. According to this configuration, manufacturing tolerance of the rotation stopper 40 can be ensured.

Further, in the case of the present embodiment, when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, deformation of the plug body 16, particularly the leg cylinder portion 52, is suppressed, and the deformation of the plug body 16 is suppressed. The locked state between the closing body locking protrusion 52A and the closing body locking recess 53A of the closing body 15 is difficult to be released. Therefore, by rotating the lid 13 around the hinge 12 with respect to the cap body 11, the spout 11A can be opened more reliably, and the operability at the time of opening can be improved.

Furthermore, in the case of the present embodiment, the leg tube portion 52 of the plug removal body 16 is sandwiched between the outer tube portion 53 and the shaft portion 54, and elastic deformation of the leg tube portion 52 in the plug removal radial direction is suppressed. , when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, it is possible to more reliably prevent the plug removal body 16 from slipping out from the closure body 15. Furthermore, since the head portion 51 of the cap removal body 16 is supported from below by the support portion 35 of the lid body 13, when the lid body 13 is rotated around the hinge 12 with respect to the cap body 11, the lid body 13 is pulled up. Force can be smoothly transmitted to the head portion 51. Thereby, the weakened portion 14 can be broken more reliably.

In addition, in the case of the present embodiment, since the capper remover 16 moves downward in the insertion hole 31A with respect to the lid 13 as the unsealing operation is performed, the user can make sure that the top surface of the capper remover 16 is aligned with the top surface of the lid 13. By observing that the hinge cap 1 is in a lowered position, it can be easily determined that the hinge cap 1 has already been opened.

[Second embodiment]
A second embodiment of the present invention will be described below with reference to FIGS. 4 and 5.
The basic structure of the hinge cap of the second embodiment is the same as that of the first embodiment, and the structure of the rotation stopper is different from that of the first embodiment. Therefore, in this embodiment, description of the basic configuration will be omitted.
FIG. 4 is a diagram showing the hinge cap 5 of this embodiment, and is a longitudinal sectional view of the hinge cap 5 in a closed state. FIG. 5 is a plan view of the lid in an open state.
In FIGS. 4 and 5, the same reference numerals are given to the same components as those in the drawings used in the first embodiment, and explanations thereof will be omitted.

As shown in FIGS. 4 and 5, in the hinge cap 5 of the present embodiment, the rotation stopper 60 is connected to a lid-side uneven portion 62 (lid-side engaging portion) formed on the lid 61 and a closure body 63. It has a formed closure body side uneven portion 64 (closure body side engagement portion). The lid body-side unevenness portion 62 and the closure body-side unevenness portion 64 mutually restrict movement of the cap removal shaft O' in the circumferential direction by engaging with each other. In the case of this embodiment, each of the lid-side uneven portion 62 and the closure-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 has a triangular cross-sectional shape perpendicular to the vertical direction that is pointed toward the inside in the radial direction of the plug. It is composed of shaped ridges. Between the two adjacent lid-side ribs 66 is a groove 67 having a V-shaped cross section perpendicular to the vertical direction. The lid body side rib 66 is formed to extend in the vertical direction along the inner circumferential surface of the surrounding cylinder portion 36 of the lid body.

The closure body side unevenness portion 64 has a configuration that fits into the lid body side unevenness portion 62. That is, in the closure body side uneven portion 64, the closure body side ribs 68 extend in the vertical direction and are formed of triangular protrusions whose cross-sectional shape orthogonal to the vertical direction is pointed outward in the radial direction of the plug. . A groove 69 is formed between two adjacent closure body side ribs 68 and has a V-shaped cross section perpendicular to the vertical direction. The closure body side rib 68 is formed to extend in the vertical direction along the outer circumferential surface of the outer cylinder portion 53. Therefore, the lid-side rib 66 of the lid-side uneven portion 62 and the groove 69 of the closure-side uneven portion 64 fit into each other, and the groove 67 of the lid-side uneven portion 62 and the closure-side rib 68 of the closure-side uneven portion 64 fit into each other. Fit together.

Note that the cross-sectional shape of each uneven portion 62, 64 does not necessarily have to be triangular, and may be, for example, quadrangular. Further, each of the uneven portions 62 and 64 does not necessarily have to be composed of a protrusion and a groove extending in the vertical direction, and may be composed of, for example, a protrusion and a hole.
The rest of the structure of the hinge cap 5 is the same as the hinge cap 1 of the first embodiment.

Also in the hinge cap 5 of this embodiment, since the rotation of the closing body 63 with respect to the lid body 61 is suppressed by the action of the rotation stopper 60, there is no fear that the closing body 63 will interfere with the spouting cylinder part 25, and the lid body The same effects as in the first embodiment, such as improved usability when closing the cover 61, can be obtained.

Further, in the case of the present embodiment, the rotation stopper 60 has a lid side unevenness part 62 and a closure body side unevenness part 64 which are arranged along the radial direction of the plug. are fitted into each other. Therefore, with a simple configuration, it is possible to reliably suppress rotation of the closure body 63 around the cap removal axis with respect to the lid body 61.

Note that the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention.
For example, the rotation stopper 40 of the first embodiment has a configuration in which two closure body side ribs 43 sandwich one lid body side rib 37, but contrary to this configuration, two lid body side ribs sandwich one lid body side rib 37. It may have a configuration in which two closure body side ribs are sandwiched. In addition, for example, if the closure body has an asymmetrical shape and is likely to interfere with the dispensing barrel when rotated in a specific direction, it is not always necessary to have a configuration in which two ribs sandwich one rib. It is also possible to provide only one side with a rib that suppresses rotation of the side where the closing body tends to interfere with the spouting cylinder.

Further, in the above embodiment, an example has been given in which the plug removal body 16 and the lid bodies 13, 61 are formed as separate bodies, and the plug removal body 16 is attached to the insertion hole 31A of the lid bodies 13, 61. The body only needs to have a function of connecting the closure body to the lid body, and instead of the above configuration, it may be formed integrally with the lid body.

Further, in the case where the cap removal body and the lid body are formed as separate bodies, in the above embodiment, the cap removal body 16 and the support portions 35 of the lid bodies 13 and 61 are not in contact with each other in the lid closed state, and the lid body 13 , 61 around the hinge 12, the cap removal body 16 and the support portion 35 come into contact and the downward movement of the cap removal body 16 is restricted. A structure may be adopted in which the plug remover and the support part come into contact with each other and the downward movement of the plug remover is regulated. Moreover, the insertion hole 31A does not necessarily need to be provided in the lids 13, 61. Furthermore, any form may be used as long as the engaging part on the lid side and the engaging part on the closing body side engage when the lid is closed, and when the lid is opened, the closing body side is broken and transferred to the lid side. Good too.

Further, the shape of the spout 11A is not limited to an ellipse shape elongated in the front-rear direction, but may be other shapes such as a perfect circle shape or a polygonal shape. The cap body 11 has a capped cylinder shape and has a mounting cylinder part 22 that surrounds the mouth part 3 of the container body 2 from the outside in the radial direction. The shape is not limited to a cylindrical shape with a top, and may have other shapes such as a plate shape. Moreover, although the support portion 42 is formed at a position shifted forward from the cap axis O, it may be formed at another position, such as being formed coaxially with the cap axis O. However, when the lid bodies 13, 61 are rotated around the hinge 12 with respect to the cap body 11, the weakened portions 14 are sequentially broken from the front end, so the strut portion 42 is shifted forward from the cap axis O. It is preferable that it be formed at a location.

Further, the specific descriptions of the number, shape, arrangement, constituent materials, etc. of each component constituting the hinge cap are not limited to the above embodiments, and can be changed as appropriate. Further, the shape of the hinge cap and the container body is not limited to a cylindrical shape, but may have other shapes such as an ellipse shape or a polygonal cylindrical shape.
