Japanese Patent No. 4456306

In the configuration of Patent Document 1, the knob used when opening the lid is arranged at a position away from the locking piece in the circumferential direction. For this reason, it is difficult for force to be transmitted from the knob portion to the locking piece, and there is room for improvement in operability at the time of unsealing.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hinge cap with improved operability when unsealed.

In order to solve the above-described problems, a hinge cap according to an aspect of the present invention includes a fixing portion fixed to the mouth portion of a container body in which contents are stored, and a hinge cap rotatable about the fixing portion with respect to the fixing portion. a capped tubular cover connected to the fixed portion, wherein the fixed portion includes a fixed tubular portion surrounding the mouth portion; a locking protrusion projecting radially outward from the fixed tubular portion; and the lid includes a knob projecting radially outward from a peripheral wall, and a locking piece connected to the peripheral wall via a weakened portion and locked to the locking projection. the positions of the knob portion and the locking piece in the circumferential direction are at least partially aligned with each other, the locking piece is positioned radially outward of the peripheral wall, and the locking portion A through hole penetrating the knob in the vertical direction is formed in a portion facing the piece in the vertical direction. An accommodating portion for accommodating the locking piece is formed between the tubular portion and the outer tubular portion .

According to the above aspect, when the lid is opened for the first time, the weakened portion is broken, so that the locking piece that is locked by the locking protrusion is separated from the lid. Accordingly, the user can confirm whether or not the container is unopened by visually recognizing the locking piece. Moreover, since the positions of the knob and the locking piece in the circumferential direction are at least partially aligned with each other, locking from the knob is easier than when the knob is separated from the locking piece in the circumferential direction. Power is easily transmitted to one side. Thereby, the operability at the time of unsealing can be improved.
Furthermore, a through-hole is formed in the knob portion so as to pass through the knob portion in the vertical direction. As a result, for example, when the hinge cap is molded by a mold, the through hole can be used as a passage hole for allowing the part of the mold that forms the locking piece to reach below the knob. Therefore, it is possible to improve the moldability of the hinge cap. Also, after the locking piece is separated from the lid, the locking piece can be retained in the housing.

Further, a hinge cap according to an aspect of the present invention includes: a fixed portion fixed to the mouth portion of a container body in which contents are contained; a cylindrical lid body, wherein the fixing portion has a fixed cylindrical portion that surrounds the mouth portion, and a locking protrusion that projects radially outward from the fixed cylindrical portion; The body has a knob projecting radially outward from a peripheral wall, and a locking piece connected to the peripheral wall via a weakened portion and locked to the locking projection, wherein the knob and each position of the locking piece in the circumferential direction coincides with each other at least in part, the locking piece is positioned radially outside the peripheral wall, and faces the locking piece in the vertical direction at the knob portion. A through hole vertically passing through the knob portion is formed in the portion to be engaged, and an inner inclined surface extending radially inward as it goes upward is formed in the outer peripheral surface of the locking projection. The knob portion may be formed with an outer inclined surface that faces the inner inclined surface in the radial direction and extends radially inward as it goes upward.

In the hinge cap of the aspect described above, since the through hole is formed in the knob, the rigidity of the knob is reduced. For this reason, when opening the lid, an operation may be performed in which the knob is pushed inward in the radial direction to move the knob upward together with the peripheral wall. Even when such an operation is performed, the lid body can be opened smoothly by the sliding between the outer inclined surface of the knob and the inner inclined surface of the locking projection.

According to the aspect of the present invention, it is possible to provide a hinge cap with improved operability when unsealed.

The first seal cylinder 23 is fitted to the pouring tube portion 14 from the outside in the radial direction, and the second seal tube 24 is fitted to the pouring tube portion 14 from the inside in the radial direction. The extraction cylinder part 14 is sealed by the first seal cylinder 23 and the second seal cylinder 24 . The pouring tube portion 14 may be sealed with the two seal cylinders 23 and 24 as in the present embodiment, or the pouring tube portion 14 may be sealed with only one of the seal cylinders 23 and 24. may

The knob portion 25 protrudes radially outward from the lower end portion of the peripheral wall 22 . As shown in FIG. 1, the knob portion 25 is formed with a through hole 25a. The through hole 25a is located in a portion of the knob portion 25 that faces the locking piece 26 in the vertical direction. In plan view, the locking protrusion 15, the locking piece 26, and the weakened portion 27 are visible through the through hole 25a. The locking piece 26 is connected to the lower end of the peripheral wall 22 via two weakened portions 27 . The two weakened portions 27 are arranged so as to sandwich the locking piece 26 therebetween in the circumferential direction.

The weakened portion 27 is a portion that is broken when the lid body 20 is opened for the first time, that is, when the capped container provided with the hinge cap 1A is opened. In this embodiment, the weakened portion 27 is formed in a dotted shape. Note that the number and shape of the weakened portions 27 can be changed as appropriate.

As shown in FIG. 1, the locking piece 26 is positioned between the hinge H and a portion of the knob 25 forward of the through hole 25a in plan view. Circumferential positions of the locking piece 26 and the knob 25 coincide with each other. In this embodiment, the width of the locking piece 26 in the circumferential direction is smaller than that of the knob portion 25 . In plan view, substantially the entire locking piece 26 is visible through the through hole 25a of the knob portion 25 .

As shown in FIG. 3 , the locking piece 26 is positioned radially outside (forward) of the peripheral wall 22 of the lid 20 . A concave portion 26 a is formed in the locking piece 26 . The concave portion 26 a is recessed downward from the upper end surface of the locking piece 26 . The locking projection 15 is inserted inside the recess 26a. In addition, the upward facing surface of the inner surface of the recess 26a and the lower end surface of the locking projection 15 face each other in the vertical direction. As a result, the locking piece 26 is locked to the locking projection 15, and the upward rotation of the lid 20 around the hinge H is restricted before the weakened portion 27 is broken. there is

The fixed portion 10 of the present embodiment has an outer tubular portion 11a that surrounds the fixed tubular portion 11 from the outside in the radial direction. A radial gap is formed between the outer cylindrical portion 11 a and the fixed cylindrical portion 11 . In this embodiment, this gap is used as a housing portion 11b for housing the locking piece 26. As shown in FIG. The lower end of the housing portion 11b may be closed. In this case, the locking piece 26 separated from the lid body 20 can be prevented from falling downward from the accommodating portion 11b. Note that the lower end of the housing portion 11b may not be closed. For example, when the container main body 2 has a shoulder, it is possible to block the opening at the lower end of the housing portion 11b with the shoulder. Further, by making the width of the opening at the lower end of the housing portion 11b smaller than the thickness of the locking piece 26, the locking piece 26 may be prevented from falling.

Further, as shown in FIG. 2, a window portion 11c is formed in the outer cylindrical portion 11a. The window portion 11c is formed at the front end portion of the outer cylinder portion 11a and recessed downward from the upper end surface of the outer cylinder portion 11a. When viewed from the front, the locking piece 26 is visible through the window portion 11c, and the lower end of the window portion 11c and the lower end of the locking piece 26 are approximately the same.

Next, the action of the hinge cap 1A configured as above will be described.

When the hinge cap 1A is formed by injection molding or the like, the lid 20 is opened with respect to the fixing portion 10 during molding. After molding, when the lid body 20 is rotated about the hinge H with respect to the fixed portion 10 , a part of the locking piece 26 comes into contact with the locking protrusion 15 . At this time, if the lid body 20 continues to rotate, the locking piece 26 gradually moves forward along the inner inclined surface 15 a of the locking projection 15 . When the lid body 20 rotates by a predetermined amount, the locking piece 26 climbs over the locking protrusion 15 downward. As a result, as shown in FIG. 3, the locking protrusion 15 enters the recess 26a, and the locking piece 26 is locked to the locking protrusion 15. As shown in FIG.

In the state shown in FIG. 3, when the lid body 20 is to be opened, the locking piece 26 is caught by the locking protrusion 15 . Therefore, the upward rotation of the lid 20 around the hinge H is restricted. When an upward force of a predetermined amount or more is applied to the lid body 20 , the weakened portion 27 is broken, and the locking piece 26 is separated from the lid body 20 . Thereby, the lid body 20 can be opened.

As described above, according to the hinge cap 1A of the present embodiment, when the lid 20 is opened for the first time, the locking piece 26 locked by the locking protrusion 15 is separated from the lid 20 . Accordingly, the user can confirm whether or not the container is unopened by visually recognizing the locking piece 26 . The locking piece 26 may be viewed from above through the through hole 25a or from the front through the window 11c.

In this embodiment, since the positions of the knob portion 25 and the locking piece 26 in the circumferential direction match each other, compared to the case where the knob portion 25 is separated from the locking piece 26 in the circumferential direction, the knob Force is easily transmitted from the portion 25 to the locking piece 26 . Thereby, the operability at the time of unsealing can be improved.

Further, the knob portion 25 is formed with a through hole 25a penetrating through the knob portion 25 in the vertical direction. The through hole 25a is located in a portion of the knob 25 that faces the locking piece 26 in the vertical direction. As a result, for example, when the hinge cap 1A is molded using a mold, the through hole 25a is used as a passage hole for allowing the portion of the mold that forms the locking piece 26 to reach below the knob portion 25. be able to. Therefore, it is possible to improve the moldability of the hinge cap 1A.

In addition, the fixed portion 10 has an outer cylindrical portion 11a that surrounds the fixed cylindrical portion 11 from the outside in the radial direction. formed. Thereby, after the locking piece 26 is separated from the lid body 20, the locking piece 26 can be retained in the housing portion 11b.
Furthermore, since the protruding wall 25c that protrudes downward from the tip of the knob 25 is provided, it is possible to prevent the fingers from coming into contact with the weakened portion 27 and the locking protrusion 15 when the lid body 20 is opened. can be suppressed. It is desirable that the protruding wall 25c protrudes downward at least to the same position as the lower end of the locking protrusion 15. As shown in FIG.

(Second embodiment)
Next, a second embodiment according to the present invention will be described, but the basic configuration is the same as that of the first embodiment. For this reason, the same reference numerals are assigned to the same configurations, the description thereof is omitted, and only the points of difference will be described.

As shown in FIG. 4, in this embodiment, the fixing portion 10 is fixed to the mouth portion 2a of the container body 2 by undercut fitting. More specifically, the opening 2a is formed with a protrusion 2b that protrudes radially outward. A fitting portion 11d is formed on the inner peripheral surface of the fixed tubular portion 11 so as to protrude radially inward and be undercut-fitted to the protrusion 2b.
A fitting cylinder portion 16 extending downward from the intermediate plate portion 12 is formed in the fixed portion 10 . The fitting tube portion 16 is fitted into the mouth portion 2a.

In this embodiment, the knob portion 25 is formed with an outer inclined surface 25b. The outer inclined surface 25b extends toward the wide rearward inner side as it goes upward. The outer inclined surface 25b faces the inner inclined surface 15a in the radial direction (front-rear direction).

Next, the action of the hinge cap 1B of this embodiment will be described.

Since the through hole 25a is formed in the knob portion 25, the rigidity of the knob portion 25 is reduced. Therefore, when opening the lid body 20 , an operation may be performed in which the knob portion 25 is pushed radially inward to move the knob portion 25 upward together with the peripheral wall 22 . Even when such an operation is performed, the outer inclined surface 25b of the knob portion 25 slides against the inner inclined surface 15a of the locking projection 15, so that the lid body 20 can be opened more smoothly.

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the above-described embodiment, the position of the entire locking piece 26 in the circumferential direction coincides with the knob portion 25 . However, it is sufficient that the positions of the knob 25 and the locking piece 26 in the circumferential direction coincide at least partially.

Further, in the above-described embodiment, the fixed portion 10 has the outer cylindrical portion 11a and the window portion 11c. However, the fixed portion 10 does not have to have the outer cylindrical portion 11a and the window portion 11c.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.

For example, in the hinge cap 1A of the first embodiment, the fixed tubular portion 11 may be undercut-fitted to the mouth portion 2a of the container body 2 as in the second embodiment. Alternatively, in the hinge cap 1B of the second embodiment, the fixed tubular portion 11 may be screwed to the mouth portion 2a as in the first embodiment.
