  The present invention relates to a hinge cap for a container.

  As a container for storing cosmetics, for example, there is a tube-like container as shown in Patent Document 1.

JP 2007-168825 A

  Although the hinge cap for containers is easy to open and close, it may be erroneously opened and closed by an impact or the like. Therefore, it is conceivable to strengthen the locking mechanism that fixes the cap in the closed state so that the cap does not open and close accidentally due to vibration or impact applied during transportation. However, if the locking mechanism is made strong, the daily opening / closing operation becomes troublesome and cannot withstand general use, and the force required for opening / closing varies depending on the processing accuracy, and thus the fixing force of the locking mechanism varies.

  As another measure, it may be possible to attach a seal (so-called virgin seal) or the like and fix the cap only at the time of transportation. However, it is necessary for a general consumer to remove the cap, and man-hours at the time of manufacture cannot be ignored.

  This invention is made | formed in view of such a subject, and makes it a subject to provide the hinge cap which cannot be mistakenly opened and closed.

  In the present invention, in the closed state, the lid portion is formed so that the fitting shaft of the lid portion is inclined with respect to the fitting shaft of the discharge port.

  Specifically, a hinge cap for a container to be attached to the container, which is fitted to a base part to be attached to the open end of the container, and a discharge port of the base part for discharging the contents of the container, with a hinge on the base part. A lid portion that is pivotably connected to open and close the discharge port, and the lid portion is closed when the lid portion is fitted into the discharge port and the lid portion is in contact with the base portion. In this state, the fitting shaft of the lid portion is formed so as to be inclined with respect to the fitting shaft of the discharge port.

  The inclination of the fitting axis of the lid portion is, for example, an inclination that prevents the lid portion and the discharge port from interfering with each other when the lid portion is fitted obliquely with respect to the discharge port, thereby preventing the lid portion from moving freely with respect to the base portion. To. Here, the fitting axis of the lid portion is a reference axis of the lid portion when fitting so that the lid portion matches the shape of the discharge port. The same applies to the fitting shaft of the discharge port. Therefore, even if the lid portion is fitted to the discharge port, if the fitting axis of the lid portion is inclined with respect to the fitting shaft of the discharge port, the lid portion should match the shape of the discharge port. The lid portion interferes with the inner wall of the discharge port without being fitted.

If it is the said hinge cap, since the fitting axis | shaft of a cover part inclines with respect to the fitting axis | shaft of a discharge outlet in the closed state, it will be in the state which the cover part interfered with the discharge outlet. In the closed state, if the lid part interferes with the discharge port, the sliding force is hindered by the frictional force acting between the lid part and the discharge port. It becomes difficult to open and close by mistake.

  Note that at least one of the lid portion and the base portion may have a locking portion that engages with the other and holds the fitted state of the lid portion. If such a locking portion is provided, the lid portion is unlikely to open and close erroneously even if vibration or impact is applied to the container.

  Further, the lid has a fitting shaft of the lid portion in the semi-closed state in which the lid portion is fitted to the discharge port and the lid portion is not locked to the base portion by the locking portion. It may be aligned with the fitting shaft. In the semi-closed state, when the fitting shaft of the lid is aligned with the fitting shaft of the discharge port, the lid smoothly enters the discharge port, so that the lid can be prevented from being accidentally opened or closed when vibration or impact is applied to the container. The action and the easy opening / closing operation of the lid can be achieved synergistically.

  The hinge cap for the container is less likely to be accidentally opened and closed.

  Hereinafter, embodiments of the present invention will be described. Embodiment shown below shows one aspect | mode of this invention, and this invention is not limited to the following embodiment.

  FIG. 1 is a side view of a tube container 2 to which a container hinge cap 1 according to the first embodiment is attached. As shown in FIG. 1, the hinge cap 1 includes a base 3 that is attached to the open end of the tube container 2 and a lid 5 that is rotatably connected to the base 3 via a hinge 4.

  FIG. 2 is an operation explanatory view of the hinge cap 1. As shown in FIG. 2, the hinge cap 1 opens and closes the discharge port 6 by rotating the lid 5 via the hinge 4. When the lid 5 is closed, the protrusion 7 provided on the lid 5 is fitted into the discharge port 6 and the discharge port 6 is closed. The lid 5 is provided with a link mechanism 8 that holds the open / closed state of the lid 5.

  When the lid 5 is opened and closed by the elasticity of the plastic material constituting the hinge cap 1, the link mechanism 8 deforms the fastening portion 11 that fastens the upper link 9 and the lower link 10 to generate an elastic force, The lid 5 is urged in the opening direction or the closing direction. Since the lid 5 is biased in the opening direction or the closing direction, the lid 5 is prevented from moving freely, so that the contents of the tube container 2 can be easily discharged.

FIG. 3 is an internal structural view of the hinge cap 1. As shown in FIG. 3, the hinge cap 1 is provided with a discharge port 6 inside a screw portion 12 that is screwed with a screw provided at an open end of the tube container 2. The discharge port 6 has an inner diameter that increases toward the upper side (outlet side) of the discharge port 6 so that the projection 7 provided on the lid 5 can be easily fitted. 6 is guided inside. The fitting axis (two-dot chain line) that is the central axis of the discharge port 6 is inclined with respect to a reference axis (one-dot chain line) parallel to the central axis of the tube container 2 and the screw portion 12. Therefore, when the lid 5 is closed, the fitting state between the discharge port 6 and the protrusion 7 is as follows.

  FIG. 5 shows an enlarged view of a fitting portion between the discharge port 6 and the protrusion 7 surrounded by the symbol A in FIG. FIG. 5A shows a state in the middle of closing the lid 5. Since the inner diameter of the discharge port 6 increases toward the upper side, the protrusion 7 is guided into the discharge port 6 without contacting and interfering with the periphery of the discharge port 6 in the process of closing the lid 5. .

  FIG. 5B shows the state of the lid 5 in a semi-closed state. The tip of the protrusion 7 of the lid 5 swells to form a locking portion 13. The locking portion 13 engages with the lower end of the discharge port 6 having the narrowest inner diameter. This lower end portion is called a locked portion 14, and a mechanism constituted by the locking portion 13 and the locked portion 14 is called a locking mechanism 15. When the lid 5 is closed and the locking portion 13 is engaged with the locked portion 14, the lid 5 is locked to the base portion 3 to prevent the lid 5 from moving freely. As shown in FIG. 5B, the semi-closed state refers to a state where the lid 5 is not locked to the base portion 3 by the locking mechanism 15 while the protrusion 7 of the lid 5 is fitted to the discharge port 6.

  FIG. 5C shows the state of the lid 5 in the closed state. When the lid 5 is completely closed, the locking portion 13 engages with the locked portion 14. A two-dot chain line shown in FIG. 5C indicates a fitting shaft that is a central axis of the discharge port 6. In addition, an alternate long and short dash line in FIG. 5C indicates a fitting shaft that is a central axis of the protrusion 7 of the lid 5. The fitting shaft (two-dot chain line) that is the central axis of the discharge port 6 is inclined toward the hinge 4 with respect to a reference axis parallel to the central axis of the tube container 2 or the screw portion 12 (for example, about 1 °). . As a result, when the lid 5 is in a closed state, the fitting shaft (one-dot chain line) that is the central axis of the projection 7 of the lid 5 is inclined with respect to the fitting shaft of the discharge port 6.

  Here, the locking portion 13 formed at the tip of the protrusion 7 is configured such that a play S is formed between the locking portion 13 and the locked portion 14 when the lid 5 is closed. This play S is formed for molding reasons when the hinge cap 1 is manufactured. That is, if the play S is not secured in the design of the molding die, the locking portion 13 does not engage with the locked portion 14 even if the lid 5 is closed in a mass-produced product. May occur. The play S is inevitably formed in order to prevent the occurrence of such defective products, although it is not the intention of the designer.

  However, even if such play S is formed, in the closed state, the fitting shaft (two-dot chain line) of the discharge port 6 is inclined with respect to the fitting shaft (one-dot chain line) of the protrusion 7, The protrusion 7 and the discharge port 6 interfere with each other, and the movement of the lid 5 with respect to the base 3 is prevented. The inclination may be any angle as long as the protrusion 7 and the discharge port 6 interfere with each other and the loose movement of the lid 5 with respect to the base 3 is prevented. 7 must be in a range where the tip of 7 contacts the periphery of the discharge port 6 and does not interfere.

By the way, the two-dot chain line shown in FIG. 5 (B) shows the fitting axis which is the central axis of the discharge port 6 and the fitting axis of the protrusion 7 of the lid 5. Since the lid 5 rotates around the rotation axis of the hinge 4 when opening and closing, the fitting axis of the projection 7 of the lid 5 rotates around the rotation axis of the hinge 4. As described above, the fitting shaft of the discharge port 6 is inclined with respect to the reference axis parallel to the central axis of the tube container 2 and the screw portion 12, and therefore, in the process of opening and closing the lid 5, FIG. ), The fitting shaft of the discharge port 6 and the fitting shaft of the protrusion 7 may coincide with each other. In the semi-closed state where the projection 5 is fitted to the discharge port 6 and the lid 5 is not locked to the base 3 by the locking mechanism 15, the fitting shaft of the discharge port 6 By tilting to the extent that it matches the fitting shaft, the lid 5 can be smoothly opened and closed without the projection 7 coming into contact with the inner peripheral surface of the discharge port 6 when the lid 5 is opened and closed.

  The hinge cap 1 configured as described above has the following effects. That is, in the case of the hinge cap 1 according to the present embodiment, even if there is a play S in the locking mechanism 15, the fitting shaft of the protrusion 7 is inclined with respect to the fitting shaft of the discharge port 6. Since the discharge ports 6 interfere with each other, the lid 5 can be prevented from moving with respect to the base 3. For this reason, there is no possibility that the lid 5 is erroneously opened and closed in the container or the like during the transportation of the tube container 2 and the contents of the tube container 2 jump out. Therefore, there is no need to stick a seal (so-called virgin seal) for preventing erroneous opening and closing of the lid 5, which has been conventionally required, and the manufacturing cost of the product can be greatly reduced.

  In the above embodiment, the locking mechanism 15 is provided. However, the function of preventing the loosening of the base 3 of the lid 5 due to the mutual interference between the protrusion 7 and the discharge port 6 is lost even without the locking mechanism 15. It is not a thing. Moreover, in the said embodiment, although the thin protrusion 7 was fitted in the discharge port 6, if it is in the range which can be fitted even if it inclines the fitting axis of the protrusion 7 with respect to the fitting axis of the discharge port 6, The diameters of the protrusions 7 and the discharge ports 6 may be large.

  Hereinafter, a second embodiment of the present invention will be described. FIG. 6 is an internal structure diagram of the hinge cap 21 according to the second embodiment. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  Similar to the hinge cap 1 according to the first embodiment, the hinge cap 21 is provided with a discharge port 26 on the inner side of the screw portion 12 that is screwed with a screw provided at the opening end of the tube container 2 as shown in FIG. It has been. The fitting axis (two-dot chain line), which is the central axis of the discharge port 26, is inclined with respect to a reference axis (one-dot chain line) parallel to the central axis of the tube container 2 and the screw portion 12, but the inclination direction is It is a side opposite to the hinge cap 1 according to the first embodiment. Therefore, when the lid 5 is closed, the fitting state between the discharge port 26 and the protrusion 27 is as follows.

  FIG. 8 shows an enlarged view of a fitting portion between the discharge port 26 and the protrusion 27 surrounded by the reference numeral B in FIG. FIG. 8A shows a state in the middle of closing the lid 5. Like the discharge port 6 according to the first embodiment, the discharge port 26 has an inner diameter that increases toward the upper side, so that the projection 7 does not contact and interfere with the periphery of the discharge port 6 in the process of closing the lid 5, The protrusion 27 is guided into the discharge port 26.

  FIG. 8B shows a state of the lid 5 in a semi-closed state. The tip of the protrusion 27 of the lid 5 swells to form a locking portion 13. The locking portion 13 forms a locking mechanism 15 in cooperation with the locked portion 14.

  FIG. 8C shows the state of the lid 5 in the closed state. When the lid 5 is completely closed, the locking portion 13 engages with the locked portion 14. A two-dot chain line shown in FIG. 8C indicates a fitting shaft that is a central axis of the discharge port 26. In addition, an alternate long and short dash line in FIG. 8C indicates a fitting shaft that is a central axis of the protrusion 27 of the lid 5. A fitting shaft (two-dot chain line) which is the central axis of the discharge port 26 is inclined to the opposite side of the hinge 4 with respect to a reference axis parallel to the central axis of the tube container 2 or the screw portion 12. When the lid 5 is in the closed state, the fitting shaft (dashed line) that is the central axis of the protrusion 27 of the lid 5 is inclined with respect to the fitting shaft of the discharge port 26.

As for the hinge cap 21 according to this embodiment, a play S is formed between the locking portion 13 and the locked portion 14 as in the hinge cap 1 according to the first embodiment. However, even if such play S is formed, in the closed state, the fitting shaft (two-dot chain line) of the discharge port 26 is inclined with respect to the fitting shaft (one-dot chain line) of the protrusion 27. The protrusion 7 and the discharge port 6 interfere with each other, and the movement of the lid 5 with respect to the base 3 is prevented.

  In the hinge cap 1 according to the first embodiment, as shown in FIG. 5B, the fitting shaft of the discharge port 6 and the fitting shaft of the protrusion 7 may coincide with each other. However, the hinge cap 1 according to the present embodiment is in a semi-closed state because the fitting shaft (two-dot chain line) of the discharge port 26 is inclined to the opposite side to the fitting shaft of the discharge port 6 according to the first embodiment. In this case, the fitting shaft of the discharge port 6 and the fitting shaft of the protrusion 7 do not coincide with each other.

  However, in the case of the hinge cap 21 configured as described above, the fitting shaft of the projection 27 is inclined with respect to the fitting shaft of the discharge port 26 and the projection 7 as in the hinge cap 1 according to the first embodiment. Since the discharge port 6 interferes with each other, the lid 5 is prevented from moving with respect to the base 3. For this reason, there is no possibility that the lid 5 is erroneously opened and closed in the container or the like during the transportation of the tube container 2 and the contents of the tube container 2 jump out.

  Although the hinge cap is applied to the tube container 2, it can also be applied to a bottle-shaped container as shown in FIG. 9 that contains a liquid such as a lotion. Even when the present invention is applied to a bottle-like container containing liquid, the lid 5 can be prevented from freely moving with respect to the base 3, so there is no possibility that the lid 5 may be erroneously opened and closed during transportation and the liquid in the container may jump out.

  For example, as shown in FIG. 10, the hinge cap has a large discharge opening 36, and the outside of the annular protrusion 37 a protruding from the base 3 is fitted with the inside of the annular protrusion 37 b protruding from the lid 5. It may be a combination. The fitting shaft, which is the central axis of the protrusion 37b, is inclined with respect to the central axis of the protrusion 37a, and the protrusion 37a and the protrusion 37b of the protrusion 36 interfere with each other. .
