Description

  The present invention relates to a hinge cap that can confirm an unopened state before use and can be disposed of after use.

  Some hinge caps have an annular fitting groove on the lower side and can be firmly fixed to the mouth of the container by plugging with the fitting groove. When performing, there is a problem that it is difficult to remove.

  For this reason, as a conventional hinge cap, on the outer periphery of the spout plug, two planned break portions are provided in the circumferential direction across the hinge connecting portion, and the portions defined by the planned break portions are respectively connected to the hinge connecting portion. There is one that can be separated from the container mouth by forming a picked portion by breaking it into a band while drawing, and then picking and picking up these picked portions together (see, for example, Patent Document 1).

  Hereinafter, with reference to drawings, the hinge cap 1 which is one form of this invention is demonstrated in detail.

In the figure, reference numeral 2 is a spout for pouring out the contents from the container 50. The spout 2 has an annular fitting groove n ₀ that is fixedly held in the mouth portion (hereinafter referred to as “container mouth portion”) 51 of the container 50, and the container is disposed in an inner region surrounded by the fitting groove n _0. A pouring part 3 for pouring out the contents from 50 is provided. The extraction part 3 has a cylindrical shape, and the inside thereof is partitioned by a partition wall 4. In the partition wall 4, a plug portion 4 a is partitioned by a thin fracture line L ₀ , and a pull ring 5 is integrally provided in the plug portion 4 a.

  Reference numeral 6 denotes a lid that is rotatably connected via a hinge portion 9. The lid 6 includes a top wall 7 disposed on the upper side of the pouring part 3 when fitted to the pouring stopper 2, and a peripheral wall 8 that hangs annularly from the outer edge of the top wall 7. The peripheral wall 8 is detachably hooked and locked to an annular locking portion 10 provided so as to surround the pouring portion 3 in the pouring tap 2. Thereby, as shown in FIG. 2, the lid body 6 is combined with the spout 2 to form a storage space R for the spout 3.

Reference numeral 11 denotes a longitudinally scheduled portion to be a starting point for separating the outer portion (hereinafter referred to as “outer cylinder portion 21”) of the spout 2 that forms the fitting groove n ₀ into a strip shape along the circumferential direction. As shown in FIG. 3, the longitudinal breakage portion 11 is provided on the outer peripheral surface 2 s near the connecting portion of the hinge portion 9 in the spout 2. Further, as shown in FIG. 6 (c), the longitudinal direction fracture planned portion 11 forms a vertical groove n ₁ downward from the mating surface 2f with the lid 6, and the vertical groove n ₁ and the fitting groove It is shaped as a thin connecting portion extending in the longitudinal direction between n ₀ and n ₀ .

The vertical groove n ₁ has a V-shaped cross section as shown in FIG. 3A, and the outer cylinder portion 21 has a separation start end face 21a in the radial direction (tangential direction) as shown in the enlarged portion of FIG. The end surface 21b constitutes a surface inclined with respect to the radial direction (tangential direction).

Reference numeral 12 also denotes a radial direction fracture portion that becomes a starting point for separating the outer cylinder portion 21 into a strip shape along the circumferential direction. Radial breakable portion 12 was formed between the lower end face 2e of the longitudinal groove n ₁ and Note decene 2 is shaped as a connecting portion of the thin-walled.

The code | symbol 13 is a vertical direction fracture | rupture plan part for cutting off the outer cylinder part 21 in strip shape along the circumferential direction. As shown in FIG. 3, the longitudinal direction breaking portion 13 forms a circumferential groove n ₂ so as to cross the inside of the connecting portion with the hinge portion 9 from a position close to the longitudinal groove n ₁ , and the circumferential groove n _2. And the fitting groove n ₀ is formed as a thin connecting portion extending in the circumferential direction.

Reference numeral 14 denotes a circumferential rupture scheduled portion serving as a starting point for separating the outer cylinder portion 21 into a strip shape along the circumferential direction. Circumferential breakable portion 14 is shaped as a connection portion of the thin extending circumferentially between the circumferential groove n ₂ and the fitting groove n _0. Thus, when the user opens the lid body 6 and pulls it outward, the outer cylinder portion 21 extends in the circumferential direction along the planned circumferential fracture portion 14 starting from the fracture from the vertical fracture planned portions 11 to 13. It will be separated.

According to this configuration, when separating from the container mouth portion 51 by separating the outer tube portion 21 of the spout 2 and opening the fitting groove n ₀ , the separation is along the circumferentially scheduled portion 14. Therefore, the force required for separation is relatively small. Further, the separation is carried out starting from the longitudinal direction breaking portion 11, and the outer peripheral side inclined surface 52 of the container mouth portion 51 is scheduled to be broken in the circumferential direction located below the locking portion 10 until the separation is performed. inner and parts 14 a to 14 c, because of the entire circumference sealed in the outer peripheral upper corners 21a of the fitting groove n ₀ which is formed above the circumferential breakable portion 14 a to 14 c, the strength of the cap 1 and sealing properties In particular, even when high temperature contents are filled, the sealing performance is not impaired.

  Furthermore, since the separation is performed by pulling the lid body 6, there is no need to separately provide a knob for removal. For this reason, by simplifying the configuration, the production cost can be reduced without increasing the size of the cap.

  Therefore, according to such a configuration, although it can be ruptured with a relatively small force, the procedure of separation and disposal is simple and the production cost is reduced without losing the strength and sealing performance or increasing the size of the cap 1. Can be suppressed.

  Moreover, in this embodiment, the inner tube portion 22 is integrally provided on the spout 2 with the locking portion 10 inside the outer tube portion 21. The inner cylinder portion 22 functions as a seal portion that seals the inside of the container mouth portion 51.

On the other hand, the outer cylinder part 21 holds the container mouth part 51 together with the inner cylinder part 22, but in this embodiment, an annular protrusion 21p that is hooked on the container mouth part 51 is integrally provided on the outer peripheral surface 21f. Yes. For this reason, in this embodiment, as shown in FIG. 5, a vertical groove n ₃ that divides the protrusion 21p in the vertical direction is formed. Thereby, the separation | separation which makes the vertical direction breaking plan part 11 the starting point can be performed with still smaller force.

  Further, in this embodiment, the longitudinally scheduled fracture portion 11 is configured to become thicker as it goes downward as shown in FIG. 6 (c). In this case, both ease of cutting and strength can be achieved.

Furthermore, in this embodiment, a thin connecting portion is formed between the longitudinal groove n ₁ and the lower end surface 2e of the spout tap 2, and the connecting portion is used as the radially fractured portion 12 extending radially outward. By being configured, the longitudinally fractured portion 11 can be cut with a relatively small force, but when a large force is applied to the spout 2 such as when the stopper is plugged, the longitudinally fractured portion 11. Reinforces so that it does not break, preventing the unexpected cutting. Accordingly, both ease of cutting and strength can be achieved.

Further, in this embodiment, the circumferential direction fracture scheduled portion 14 is configured such that the connecting portion C ₀ with the longitudinal direction fracture scheduled portions 11 and 13 has the thinnest thickness, as shown in FIG. As a specific example, the connecting groove C ₀ is made the thinnest by arranging the fitting groove n ₀ , the vertical groove n ₁ and the circumferential groove n ₂ closest to each other. Thereby, cutting can be started with a small force.

Further, in this embodiment, as shown in FIG. 6 (b), the portion of the connecting portion C ₀ of the longitudinal breakable portion 11 to a predetermined range (hereinafter, "cutting start portion") 14a is connected portion C ₀ It is composed of the same thin wall. And it is comprised as the transition part 14b which becomes thick gradually from the part which crossed the center of the hinge part 9 as shown in FIG.6 (b). The transition portion 14b becomes thick radially outward to a predetermined range, but thereafter, the thickness thereof becomes constant at the steady portion 14c as shown in FIG. 6 (a).

  By providing the cutting start portion 14a, the breakage easily proceeds and the lid 6 is greatly separated from the spout 2. As described above, when the lid 6 is largely separated from the spout 2, it becomes easy to apply a force for pulling the lid 6. For this reason, even if the force required for cutting at the transition portion 14b increases, it can be cut relatively easily. Further, in the steady portion 14c, the strength of the cap 1 is increased and, as shown in FIG. 6 (a), the inclined surface 52 of the container mouth portion 51 remains in pressure contact, so that the sealing performance is not deteriorated.

  In other words, if the cutting start portion 14a of the circumferentially scheduled fracture portion 14 is configured to be thinner than the transition portion 14b and the steady portion 14c, the cutting start portion 14a can be smoothly cut while In the portion 14c, the strength and sealing performance of the cap 1 can be ensured. For this reason, it is preferable to ensure the range of the stationary part 14c wider than the cutting start part 14a.

Moreover, the circumferential direction fracture | rupture scheduled part 14 can form a cut | interruption in the cutting | disconnection start part 14a. In this case, it becomes easier to start cutting the circumferentially scheduled fracture portion 14. Further, with respect to the longitudinal direction breaking portion 13, a similar cut can be formed within a predetermined range from the connection portion (C ₀ ) with the circumferential direction breaking portion 14. Further, the longitudinal direction breaking portion 13 can also be configured such that a portion within a predetermined range from the connection portion (C ₀ ) with the circumferential direction breaking portion 14 is thinner than other portions.

  Reference numeral 16 denotes a plate member that prevents the lid 6 from being opened. The plate member 16 is disposed at a position facing the connecting portion of the hinge portion 9. Further, as shown in FIG. 1A, the plate member 16 is formed with an opening A for hooking the protrusion 19 provided on the lid 6.

  Further, as shown in FIG. 1 (a), the plate member 16 is integrally provided on the mating surface 2f of the outer cylinder portion 21 of the spout 2 via a planned fracture portion 18 extending in the circumferential direction. ing. A handle 17 is provided on one side of the plate member 16. The handle 17 extends integrally from the side surface of the plate member 16 in the lateral direction. Thus, when the handle 17 provided on the plate member 16 is grasped and pulled in the circumferential direction, the plate member 16 can be separated along the planned fracture portion 18 as shown in FIG. The handle 17 can be appropriately provided according to the request of the user or the like, and the presence or absence thereof is arbitrary.

  As described above, if the plate member 16 that has the opening A for hooking the protrusion 19 provided on the lid body 6 and prevents the lid body 6 from being opened is provided on the mating surface 2f of the spout 2. The lid 6 cannot be opened unless the 6 is intentionally pushed up with a relatively large force.

  Moreover, since the plate member 16 is provided integrally with the spout 2 via the planned fracture portion 18, the lid 6 can be opened by separating the planned fracture portion 18 and separating the plate member 16. . That is, when the plate member 16 is present in the unopened state, the unopened state can be visually recognized, and the plate member 16 is removed after the lid 6 is opened. Thus, the opened state can be visually recognized.

  Therefore, according to this structure, the unopened state before use can be guaranteed. In addition, if the opening part A is arrange | positioned in the position aligned with the fracture | rupture scheduled part 18 like this form, the plate member 16 can be isolate | separated comparatively easily.

  Moreover, in this embodiment, as shown in FIG. 1 (b), a recess 20 is provided in the peripheral wall 8 of the lid 6. A protrusion 19 is disposed in the recess 20. Thus, when the lid member 6 is closed, the plate member 16 is accommodated in the recess 20 as shown in FIG.

  Thus, by storing the plate member 16 in the recess 20, the cap 1 gives a simple and clean appearance impression as shown in FIG. 1A, and avoids unexpected separation of the plate member 16. can do. In addition, although the fracture | rupture planned part 18 is comprised as a thin strip | belt-shaped part, it can also be comprised by the some connection piece arrange | positioned at intervals in the circumferential direction.

  By the way, in the case of the form mentioned above, when the cover body 6 is opened, the protrusion 19 may become obstructive. For this reason, according to this invention, a form as shown to FIGS. 8-11 is employable.
