  Hereinafter, a hinge cap 100 according to an embodiment of the present invention will be described with reference to the drawings. The hinge cap 100 includes a cylindrical portion 10 and a lid portion 20 that is attached to the cylindrical portion 10 via a hinge 30 so that the opening of the cylindrical portion 10 can be opened and closed.

  The cylindrical portion 10 of the hinge cap 100 has a closed state in which the lid portion 20 closes the opening of the cylindrical portion 10 when the lid portion 20 rotates about the hinge 30, and the lid portion 20 closes the opening of the cylindrical portion 10. It can be in an unopened state. In addition, the hinge cap 100 controls a locked state in which a lock mechanism, which will be described later, restricts rotation about the hinge 30 of the lid portion 20 and restricts the cylindrical portion 10 from being opened, and restricts rotation about the shaft. Without being able to enter the unlocked state in which the cylinder part 10 can be in the open state.

  FIG. 1 shows a perspective view of the hinge cap 100 in a locked state (FIG. 1A) and a cross-sectional view taken along the line A-A ′ (FIG. 1B). 2 shows a plan view (FIG. 2A) and a front view (FIG. 2B) of the hinge cap 100 in a locked state. 3 shows a front view (FIG. 3A) and a right side view (FIG. 3B) of the hinge cap 100 in the unlocked state.

  As shown in FIG. 1B, the hinge cap 100 can typically be used by attaching the cylindrical portion 10 to the mouth portion of the packaging container main body 200 with a stopper or the like.

(Cylinder part)
The cylinder portion 10 includes a top plate 12, a side wall 13, and a plug opening restriction portion 11. The top plate 12 is a plate-like member having an opening in the center, and has a disk shape as an example. The side wall 13 is suspended from the outer peripheral edge of the top plate 12.

  Further, as shown in FIG. 1B, the cylindrical portion 10 includes, as an example, an inner ring 14 that extends from the bottom surface of the top plate 12 inside the side wall 13 and an inner edge that surrounds the opening of the top plate 12. A partition wall 16 extending in the vertical direction from the top of the partition wall 16, a partition wall 16 provided so as to close the opening through a half cut inside the extraction wall 15, and a column 17 provided on the upper surface of the partition wall 16. And a pulled pull ring 18.

  The cylindrical portion 10 configured as described above is configured so that the front end of the mouth of the packaging container body 200 is sandwiched between the inner circumferential surface of the side wall 13 and the outer circumferential surface of the first inner ring 14, so 200 can be attached. Moreover, the pouring wall 15 can be used as a spout which curls the upper end outward to prevent dripping of the pouring liquid. Moreover, an opening can be formed in the cylindrical portion 10 by removing the partition wall 16 using the pull ring 18.

  The opening restriction part 11 constitutes a lock mechanism together with a sliding piece 21 and a recessed part 22 which will be described later. The opening restriction part 11 includes a pair of plate-like members extending from the side wall 13a, and a protruding part 11b protruding from a surface (inner surface) facing the other arm part of each arm part 11a. including. As shown in FIGS. 1 to 3, the protruding portion 11 b can have a hemispherical shape as an example, but is not particularly limited as long as the protruding portion 11 b has a shape capable of maintaining a locked state described later.

(Cover)
The lid portion 20 includes a peristaltic piece 21, a concave portion 22, a thin portion 23, a top plate 24, and a side wall 25. The top plate 24 constitutes the top of the lid portion 20 and can be formed into a disk shape as an example. The side wall 25 is suspended from the outer peripheral edge of the top plate 24. As shown in FIG. 1B, the lid portion 20 extends from the lower surface of the top plate 24 as an example, and the inner peripheral surface of the extraction wall 15 of the cylindrical portion 10 when the lid portion 20 is closed. You may provide the inner ring 26 fitted to this.

  The sliding piece 21 constitutes a lock mechanism together with the plug opening restricting portion 11 and the recessed portion 22. The peristaltic piece 21 is configured to include an insertion scheduled portion 21a and an operation portion 21b.

  The insertion-scheduled portion 21 a is a member that is inserted into a later-described recess 22 when the hinge cap 100 is unlocked. As shown in FIGS. 1 and 2, when the hinge cap 100 is locked, the side wall 25, which is the outer peripheral surface of the lid portion 20, extends from a partial region opposite to the side where the hinge 30 is provided. Formed as follows. As an example, the insertion-scheduled portion 21a has a cross section in the circumferential direction of the lid portion 20 formed in a right triangle.

  The operation part 21 b is a plate-like member that extends from below the insertion-scheduled part 21 a in the closed state of the lid part 20 and covers a part of the side wall 13 of the cylindrical part 10. As shown in FIGS. 1 and 2, the operation portion 21 b is partially sandwiched between the protruding portion 11 b of the plug opening restricting portion 11 and the side wall 13 of the cylindrical portion 10 in the locked state of the hinge cap 100. Is formed.

  As shown in FIG. 1 and FIG. 2, at the end of the operation part 21 b opposite to the insertion-scheduled part 21 a, the tube passes through the lower part of the protrusion 11 b of the opening restriction part 11 in the locked state of the hinge cap 100. You may provide the standing part 21c bent and extended in the direction orthogonal to the axial direction of the part 10. FIG. Further, as shown in FIG. 3, a display 21 d indicating that the hinge cap 100 is in the unlocked state may be attached to the surface of the upright portion 21 c opposite to the operation portion 21 b.

  The recess 22 constitutes a lock mechanism together with the plug opening restricting portion 11 and the sliding piece 21. The recessed portion 22 is a portion in which the insertion-scheduled portion 21a of the sliding piece 21 is inserted and stored in the unlocked state of the hinge cap 100 described later. The recess 22 is open to the top plate 24.

  The thin-walled portion 23 is a portion connecting the side wall 25 and the insertion-scheduled portion 21a, and is formed in a portion surrounding the extension portion of the insertion-scheduled portion 21a of the side wall 25 of the lid portion 20 as shown in FIGS. Has been. Further, the thin-walled portion 23 has a side end portion 23a that connects the side wall 25 and the planned insertion portion 21a at both side ends of the planned insertion portion 21a, and a lower end that connects the side wall 25 and the planned insertion portion 21a at the lower end of the planned insertion portion 21a. The part 23b is connected, and is formed in a shape surrounding the insertion-scheduled part 21a in a U shape. Although details will be described later, when the lock mechanism is released, the side end portion 23a is broken and the lower end portion 23b becomes a thin-walled hinge portion between the side wall 25 and the fitting-in portion 21a.

  FIG. 4 is a perspective view for explaining the shape of the recess 22. In FIG. 4, for convenience, the peristaltic piece 21, the top plate 24, and the side wall 25 are shown in a transparent manner. As an example, the width of the recess 22 along the circumferential direction of the lid portion 20 is an undercut in which the width W2 on the cylindrical portion 10 side is wider than the width W1 on the top plate 24 side of the lid portion 20 as shown in FIG. It is formed into a shape. Moreover, the width W1 is formed narrower than the width along the circumferential direction of the lid portion 20 of the planned insertion portion 21a, and the width W2 on the cylindrical portion 10 side is the width along the circumferential direction of the lid portion 20 of the planned insertion portion 21a. It is formed as described above. Furthermore, the shape in the circumferential direction of the lid portion 20 of the width W2 portion is formed in a shape corresponding to the planned insertion portion 21a so that the planned insertion portion 21a can be fitted in the locked state of the hinge cap 100.

(Hinge)
The structure of the hinge 30 is not particularly limited as long as the lid portion 20 can be connected to the cylinder portion 10 so as to be openable and closable. However, a butterfly type hinge can be suitably used so that the lid portion 20 can be easily held at a certain angle. .

(Lock mechanism)
Next, the locking mechanism of the hinge cap 100 will be described. The lock mechanism is configured by the plug opening restriction portion 11, the swing piece 21, and the opening 22. The lock mechanism can switch the hinge cap 100 from the locked state to the unlocked state by rotating the peristaltic piece 21 around the lower end portion 23b, which is a portion of the thin portion 23 near the cylindrical portion 10, as an axis. FIGS. 5A and 5B are a cross-sectional view (left side view) and a perspective view (right side view) showing the periphery of the sliding piece 21 and the recess 22 until the hinge cap 100 is changed from the locked state to the unlocked state. . In the perspective view, for the sake of convenience, a part of the lid portion 20 and the plug opening restriction portion 11 is shown in a transparent manner.

  First, the hinge cap 100 in the locked state will be described. As shown in FIGS. 1 and 2, in the hinge cap 100 in the locked state, the operation portion 21 b is partially sandwiched between the protruding portion 11 b of the plug opening restricting portion 11 and the side wall 13 of the cylindrical portion 10. Yes. For this reason, the rotation of the lid portion 20 about the hinge 30 is restricted by the contact between the operation portion 21b or the standing portion 21c and the protruding portion 11b. In the locked state, the thin portion 23 is not broken.

  Next, in order to release the locked state, a force that pushes upward is applied to the sliding piece 21 so as to rotate about the lower end portion 23b of the thin portion 23 as an axis. Specifically, as shown by an arrow in FIG. 5A, the operation portion 21b or the upright portion 21c is arranged on the top surface of the lid portion 20 so that the lower end portion 23b of the thin portion 23 becomes a thin hinge portion and constitutes a rotation shaft. Lift up toward 24. As a result, the side end portion 23a other than the portion serving as the rotational axis of the thin portion 23 is stretched between the insertion-scheduled portion 21a and starts to break from the top plate 24 side of the lid portion 20. Then, as shown in FIG. 5A, the insertion-scheduled portion 21 a around the broken side end portion 23 a enters the portion where the tip is formed in the width W <b> 1 of the recess 22 with the rotation. As described above, since the width W1 of the recess 22 is narrower than the width of the insertion-scheduled portion 21a, the insertion-scheduled portion 21a is pushed into the recess 22 by applying a force greater than a predetermined size to the sliding piece 21. It is.

  At substantially the same time, the operation part 21 b or the standing part 21 c of the sliding piece 21 comes into contact with the protruding part 11 b of the plug opening restricting part 11. Further, by further applying force to the peristaltic piece 21, each arm part 11 a of the plug-opening restricting part 11 is elastically deformed so as to be pushed and expanded in the circumferential direction of the cylindrical part 10 by the peristaltic piece 21. As a result, as shown in FIG. 5A, the sliding piece 21 can get over the protruding portion 11b of the opening restriction portion 11, and the hinge cap 100 is unlocked.

  Next, by further rotating the peristaltic piece 21 and pushing the tip of the insertion-scheduled part 21a into the recessed part 22 while breaking the side end part 23a of the thin-walled part 23, as shown in FIG. The portion formed in the width W2 of the recess 22 is reached. As described above, the concave portion 22 is formed so that the width W2 is equal to or larger than the width of the planned insertion portion 21a, and the concave portion 22 is formed in a shape corresponding to the rotated planned insertion portion 21a. For this reason, when the insertion plan part 21a reaches the part of the width W2 of the recessed part 22, it will insert in the said part. As a result, the rotation of the sliding piece 21 in the direction of the unplugging restricting portion 11 is restricted, and the hinge cap 100 once in the unlocked state cannot be returned to the locked state again.

  As described above, according to the hinge cap 100, virginity can be secured without separating the sealing member by the lock mechanism. Further, in the hinge cap 100, since the sealing member is not separated, a gap is generated in the cylindrical portion 10 after being in the unlocked state, and the poured content liquid enters the gap and deteriorates the appearance. There is nothing.

  Further, in the case where the above-described standing portion 21c is provided, the standing portion 21c rotates approximately 90 ° before the insertion-scheduled portion 21a is fitted into the width W2 portion of the concave portion 22, so as shown in FIG. The display 21d attached to the upright portion 21c is visible from a direction orthogonal to the axial direction of the cylindrical portion 10. As a result, the user of the hinge cap 100 is surely unlocked by at least one of the thin-walled portion 23 where the side end portion 23a is broken, the rotating perforated piece 21, and the display 21d that is visible from the front direction. It can be seen visually.

  The strength of the thin-walled portion 23 can be designed, for example, such that the rupture is caused by a force comparable to the force necessary to move the sliding piece 21 over the protruding portion 11b of the opening restriction portion 11. By designing the thin-walled portion 23 in this way, for example, when the locked state is released, the side end portion 23a of the thin-walled portion 23 can be quickly broken, so that the virginity is ensured more reliably.

  In the above description, the case where the pull ring 18 is provided in the cylindrical portion 10 is illustrated, but the pull ring 18 may not be provided in the hinge cap 100. By not providing the pull ring 18, it is possible to suppress the generation of dust due to the pull ring 18 generated when the plug is opened and the partition wall 16 connected to the pull ring 18.

  The lock mechanism described above does not generate a part to be disconnected when opening the plug, and can realize a lock state that restricts the tube portion from being opened by rotating the lid portion around the hinge, and once locks. The structure is not limited as long as the trace is generated in the released state.

(Modifications, etc.)
In the hinge cap 100 according to the embodiment, the width in the circumferential direction of the lid portion 20 of the concave portion 22 is formed in two stages, and the virgin property is ensured as a structure that does not return once it is pushed in and inserted. However, the hinge cap 100 is formed such that the step between the width W1 and the width W2 is removed by applying a predetermined force to the peristaltic piece 21 after insertion, or the recess 22 is formed with a constant width. In addition, it may be formed so that the fitting is easily removed. By forming the recess 22 in this way, the hinge cap can be repeatedly used between the locked state and the unlocked state, and inadvertent opening can be prevented.

  The material of the hinge cap 100 is not particularly limited, and a linear low density polyethylene (LLDPE) or a material obtained by mixing high density polyethylene (HDPE) or low density polyethylene (LDPE) with this can be suitably used. Moreover, by using these materials, it is possible to manufacture at low cost with one part using, for example, injection molding.

  When the hinge cap 100 is manufactured as a single part by injection molding, for example, it can be molded as follows. That is, first, the hinge cap 100 which is opened with the thin portion 23 is formed by injection molding. Thereafter, the lid portion 20 is rotated about the hinge 30 as a shaft, and the operation portion 21b of the sliding piece 21 is moved over the protruding portion 11b of the plug opening restricting portion 11 without breaking the thin portion 23 to be in a locked state.

  In such a manufacturing process of the hinge cap 100, in order to make it easier for the operating portion 21b to get over the protruding portion 11b, the surface formed by the pair of protruding portions 11b that the operating portion 21b gets over is formed as follows, for example. Can do. That is, the taper angle of the portion where the width narrows from the lid portion 20 side toward the tube portion 10 side of the surface formed by the pair of protrusions 11b, and the taper angle of the portion where the width narrows from the tube portion 10 side to the lid portion 20 side. Make it more lenient. FIG. 6 shows a front view of a hinge cap 101 according to a modified example including a protruding portion 11b 'shaped so that the operating portion 21b can easily get over the protruding portion 11b during manufacture. As shown in FIG. 6, in the hinge cap 101, the surface over which the operation portion 21b formed by the pair of protruding portions 11b ′ gets over is a tapered surface with a width narrowing from the lid portion 20 side toward the tube portion 10 side, and a tube It is comprised by the surface orthogonal to the axial direction of the part 10. FIG.

  INDUSTRIAL APPLICABILITY The present invention can be used for a hinge cap that is used by being attached to the mouth of a container body.
