Description

  The present invention relates to a hinge cap for a container for high viscosity liquid.

  The shampoo container includes a bottle and a cap having a spout. When the shampoo is used, after the spout has been lowered, the shampoo is drained by drooping due to the weight of the shampoo and compressing the side wall of the bottle by the user.

  In this container, when the remaining amount of shampoo decreases, the position of the liquid level of the shampoo in the bottle moves away from the spout of the bottle. Since the viscosity of the shampoo is high, the time from when the spout is lowered to when the shampoo is discharged becomes longer. For this reason, it is troublesome for the user to use up the shampoo.

  In order to reduce the cost, a large-capacity bottle may be used as a shampoo container. In this container, a dispenser having an accumulator and a guide tube is generally used as a cap. In this container, the shampoo put into the bottle is discharged by pushing down the saddle of the dispenser. In this case, the spout need not be lowered because the shampoo is discharged.

  In a bottle equipped with a dispenser, when the remaining amount of shampoo is low, the suction port of the guide tube that has been immersed in the shampoo comes out of the shampoo. In this state, the dispenser sucks air. For this reason, even if the shampoo remains, even if the saddle is pushed down, the shampoo is not discharged. The container cannot be turned upside down with the dispenser attached. For this reason, it is not easy for the user to use up the shampoo.

  Problems similar to those described above also occur in liquid containers such as rinses, treatments, conditioners, body soaps, and lotions.

  Various studies have been made to easily use these high-viscosity liquids. Examples of the examination results are disclosed in Japanese Patent Application Laid-Open Nos. 2006-240634 and 2012-232784.

  Japanese Patent Laid-Open No. 2006-240634 discloses a hinge cap for a container for high viscosity liquid. FIG. 12 shows the hinge cap 2. The cap 2 includes a body 4 and a sealing body 6. The sealing body 6 closes the spout provided on the body 4. The body 4 and the sealing body 6 are connected by a hinge 8. The cap 2 is screwed into the bottle mouth.

  In the hinge cap 2, the sealing body 6 rotates with respect to the body 4 about the hinge 8. Thereby, the spout of the trunk | drum 4 is exposed.

  A flange 10 is provided on the upper portion of the hinge cap 2. The outer diameter of the flange 10 is larger than the outer diameter of the body 4. For this reason, by using this cap 2, the container can be placed on the floor surface with the flange 10 facing down. Since the bottle is held upside down, the liquid accumulated at the bottom of the bottle hangs down by its own weight and accumulates in the cap 2 portion. For this reason, as soon as the user removes the sealing body 6, the liquid is discharged from the spout. The cap 2 can contribute to the use up of the liquid. The user can easily use up the shampoo by using the cap 2 for the shampoo container or by changing the dispenser of the container to the cap 2 when the remaining amount of the shampoo is low.

  Japanese Unexamined Patent Application Publication No. 2012-232784 discloses a hinge cap for a container for high viscosity liquid. This cap also has a flange whose outer diameter is larger than the outer diameter of the fuselage. This flange is provided with a notch. This notch contributes to the improvement of cap productivity as follows.

  A cap used in a container for a high viscosity liquid is molded by putting a resin composition into a mold cavity and heating and pressurizing the resin composition. FIG. 13 shows a cross section of the cap 2 of FIG. 12 in a state where the sealing body 6 is opened. The cavity of the mold is configured in the form shown in FIG.

  As illustrated, the flange 10 overlaps the hinge 8 in the vertical direction because the outer diameter of the flange 10 is larger than the outer diameter of the body 4. This overlap hinders removal of the cap 2 from the mold. For this reason, in order to mold the cap 2, it is necessary to use a mold that takes into account the removal of the cap. A portion where the flange 10 and the hinge 8 overlap is also referred to as an undercut.

  Considering removal of the cap with the undercut from the mold, the mold may be composed of a number of parts. Such a mold is expensive. In addition, since the number of parts is large, it takes time to take out the cap 2. In such a form, it is difficult to produce the cap 2 inexpensively and stably. This form of cap is inferior in productivity.

  In the hinge cap disclosed in Japanese Patent Application Laid-Open No. 2012-232784, the flange has a notch so that the flange and the hinge do not overlap. For this reason, undercut does not occur in this cap. This cap is excellent in productivity.

  The hinge cap 2 disclosed in Japanese Patent Application Laid-Open No. 2006-240634 includes a flange having an outer diameter larger than the outer diameter of the body. As a result, the user can easily use up the shampoo. However, as described above, this form of cap is inferior in productivity. In the hinge cap disclosed in Japanese Patent Application Laid-Open No. 2012-232784, the flange has a notch. This contributes to an improvement in cap productivity. However, the notch made on the flange detracts from the appearance of the container. In addition, this notch is easily caught by other objects when carrying or using. This container is difficult to handle. This notch detracts from the commercial value of the shampoo.

  An object of the present invention is to provide a hinge cap for a high-viscosity liquid container that does not impair the appearance and ease of handling, is excellent in productivity, and can easily use up the high-viscosity liquid.

  The hinge cap according to the present invention includes a cylindrical body having a spout at an upper portion thereof, a lid that closes the spout, and a hinge that rotatably connects the body and the lid. The lid includes a main body fitted on the upper portion of the body and a flange protruding from the main body. The main body and the flange are integrated by fitting connection.

  Preferably, the ratio of the maximum width of the lid to the maximum width of the body is 1.01 or more and 3.00 or less.

  Preferably, the flange has a recess having a first protrusion on its inner peripheral surface, the main body has a second protrusion on its outer peripheral surface, and the main body is fitted into the recess. At this time, the flange and the main body are integrated by engaging the first protrusion and the second protrusion.

  The flange has a protrusion having a first protrusion on its outer peripheral surface, the body has a recess having a second protrusion on its inner peripheral surface, and the protrusion is fitted into the recess. At this time, the flange and the main body may be integrated by engaging the first protrusion and the second protrusion.

  The flange has a recess in which an internal thread is threaded on its inner peripheral surface, and a male screw is threaded on the outer peripheral surface of the main body, and the main body and the concave portion are screwed together. The flange and the main body may be integrated.

  The flange has a convex portion threaded with a male screw on its outer peripheral surface, and the main body has a concave portion with a female screw threaded on its inner peripheral surface. The flange and the main body may be integrated by screwing the recess.

  The container for high-viscosity liquid according to the present invention includes a bottle into which a high-viscosity liquid is charged and a hinge cap that is fitted into the mouth of the bottle. The hinge cap includes a cylindrical body having a spout at an upper portion thereof, a lid that closes the spout, and a hinge that rotatably connects the body and the lid. The lid includes a main body fitted to the upper portion of the body and a flange projecting radially outward from the main body. The main body and the flange are integrated by fitting connection.

  The hinge cap of the container for high viscosity liquid according to the present invention includes a flange protruding from the main body of the lid. Thereby, the user of this container can use up a shampoo easily. In the hinge cap, the lid body and the flange are integrated by fitting and coupling. The flange and the cap portion other than the flange are manufactured separately. Finally, it is integrated by fitting one into the other. For this reason, an undercut is not formed in each manufacture. These can be easily taken out from the respective molds. This cap is excellent in productivity.

  In this hinge cap, since an undercut is not formed, it is not necessary to provide a notch in the flange. This cap does not impair the appearance of the container. Moreover, since there is no notch, this container is easy to handle.

  Due to the various requirements for the design of the container, the cap lid takes various shapes. Various patterns and characters are engraved on the upper surface of the lid. With the cap according to the present invention, a lid having these shapes and patterns can be created simply by changing the mold for the flange. Thereby, the hinge cap corresponding to various products can be produced cheaply.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1A is a side view showing a hinge cap 20 according to the present invention, and FIG. 1B is a plan view thereof. FIG. 2 shows a cross section of the cap 20 taken along the line II-II in FIG. The hinge cap 20 includes a body 22, a lid 24, and a hinge 26. The body 22 is cylindrical. A spout 31 is provided on the upper portion of the body 22. The aforementioned high viscosity liquid can pass through the spout 31. A female screw 32 is provided on the inner peripheral surface of the body 22. This female screw corresponds to the male screw at the mouth of the bottle. This cap 20 is screwed into the bottle.

  The lid | cover 24 is disk shape. The lid 24 includes a main body 28 and a flange 30. The main body 28 has a cylindrical shape with an upper portion closed. As shown in FIG. 2, the main body 28 is provided with a cylinder 29 protruding from the lower surface thereof. In the cap 20, the main body 28 is fitted on the upper portion of the body 22. When the main body 28 is fitted to the body 22, the cylinder 29 is inserted into the spout 31 of the body 22. As a result, the spout 31 of the body 22 is closed.

  The flange 30 extends radially outward from the main body 28 above the main body 28 of the lid 24. The flange 30 protrudes from the main body 28. The outer periphery of the flange 30 has a circular shape. The upper surface of the flange 30 is flat.

  The hinge 26 connects the body 22 and the lid 24. In the cap 20, when the lid 24 is lifted by placing a finger on the flange 30 of the lid 24, the lid 24 rotates with respect to the body 22 about the hinge 26. This is shown in FIG. In the drawing, a double-headed arrow A indicates the rotation direction of the lid 24. In the cap 20, the lid 24 and the body 22 are rotatably connected by the hinge 26.

  In the lid 24 of the hinge cap 20, the main body 28 and the flange 30 are integrated by fitting and coupling. FIG. 3 shows a state before the flange 30 is fitted to the main body 28 of the lid 24. Here, the cap 20 provided with the lid 24 before the flange 30 is fitted is referred to as a “flangeless cap 34”. In FIG. 3, an arrow X indicates the vertical direction of the hinge cap 20.

  FIG. 4 is a plan view of the flange 30 before being fitted to the main body 28 as viewed from below. As shown in FIGS. 3 and 4, the flange 30 includes a recess 36 on the lower surface thereof. The recess 36 has a cylindrical shape. In FIG. 4, what is indicated by an arrow Y is the circumferential direction of the cylinder. The symbol O represents the center of this cylinder. A direction from the center O toward the inner peripheral surface of the cylinder is referred to as a radial direction.

  Four first protrusions 38 are provided on the inner peripheral surface of the recess 36. Each first protrusion 38 extends in the circumferential direction. These protrusions are aligned in the vertical direction. A double-headed arrow R1 represents the distance from the center O to the radially inner end of the first protrusion 38. A double arrow RF represents a radial distance from the center O to the inner peripheral surface of the cylinder. In FIG. 3, the arrow L <b> 1 is the vertical distance from the bottom surface 48 of the recess 36 to the upper end of the first protrusion 38. A groove 40 extending in the vertical direction is provided on the inner peripheral surface of the recess 36. The groove 40 extends from the bottom surface 48 of the recess 36 to the surface.

  FIG. 5 is a plan view of the flangeless cap 34 as viewed from above. As shown in FIGS. 3 and 5, the main body 28 has a convex portion 42 on its upper surface. The convex portion 42 has a cylindrical shape. As in FIG. 4, what is indicated by an arrow Y in FIG. 5 is the circumferential direction of this cylinder. The symbol O represents the center of this cylinder. The direction from the center O toward the outer peripheral surface of the cylinder is the radial direction.

  Four second protrusions 44 are provided on the outer peripheral surface of the convex portion 42. Each of the second protrusions 44 extends in the circumferential direction. These protrusions are aligned in the vertical direction. A double-headed arrow R2 represents a distance from the center O to the radially outer end of the second protrusion 44. A double arrow RB represents a radial distance from the center O to the outer peripheral surface of the cylinder. In FIG. 3, an arrow L <b> 2 is a vertical distance from the tip 50 of the convex portion 42 to the lower end of the second protrusion 44. A third protrusion 46 extending in the vertical direction is provided on the outer peripheral surface of the convex portion 42. The third protrusion 46 extends from the tip 50 of the convex portion 42 to the root.

  Here, the above-mentioned distance RB is smaller than the distance RF. In other words, the outer diameter of the convex portion 42 is smaller than the inner diameter of the concave portion 36. The distance R2 is larger than the distance R1. The third protrusion 46 is formed in a size that fits into the groove 40. Furthermore, when the convex part 42 and the recessed part 36 are overlapped so that the position of the third projecting part 46 and the position of the groove 40 are aligned, the first projecting part 38 of the concave part 36 and the second projecting part 44 of the convex part 42 are It is provided at an overlapping position when viewed from above the cap 20. The distances L1 and L2 are the same value.

  In order to fit the flange 30 to the main body 28, the third protrusion 46 and the groove 40 are aligned, and the convex portion 42 of the main body 28 is pressed against the concave portion 36 of the flange 30. Since the distance RF is larger than the distance RB, the convex portion 42 enters the concave portion 36 halfway. Since the distance R <b> 2 is greater than the distance R <b> 1, the first protrusion 38 abuts on the second protrusion 44. Here, when the convex portion 42 is further pressed, the convex portion 42 is deformed inward in the radial direction. In other words, the convex portion 42 is deformed in a direction in which the distance R2 is reduced. Thereby, the convex portion 42 is further pushed into the concave portion 36. When the second protrusion 44 is pushed beyond the first protrusion 38, the deformation of the protrusion 42 is restored. By this restoration, the distance R2 returns to the original value. Thereby, the convex part 42 does not come out of the concave part 36. The first protrusion 38 and the second protrusion 44 are engaged with each other. Since the distances L1 and L2 are the same, at this time, the tip of the convex portion 42 abuts against the bottom surface 48 of the concave portion 36. The convex portion 42 does not slide in the vertical direction with respect to the concave portion 36. Further, since the third protrusion 46 is fitted in the groove 40, the convex portion 42 does not rotate in the circumferential direction with respect to the concave portion 36. Thereby, the flange 30 is fitted to the main body 28. The flange 30 and the main body 28 are integrated.

  The number of the first protrusions 38 and the second protrusions 44 is not limited to four. The 1st projection part 38 and the 2nd projection part 44 may each be comprised by the ring shape along the circumferential direction. The number of the third protrusions 46 and the number of grooves 40 is not always one. These shapes and numbers are appropriately changed depending on the sizes and shapes of the main body 28 and the flange 30. Further, the main body 28 may not include the convex portion 42. The main body 28 may be fitted into the flange 30 as it is. In this case, the second protrusion 44 and the third protrusion 46 are provided on the outer peripheral surface of the main body 28. The distance from the center O of the main body 28 to the outer peripheral surface is RB so that the main body 28 is just fitted into the recess 36 of the flange 30.

  The cap 20 is formed from a resin composition. This resin composition contains a base resin. Examples of the base resin include thermoplastic resins such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, nylon, and polystyrene. From the viewpoint of versatility and processability, polyethylene, polypropylene, and polyethylene terephthalate are more preferable. Note that these recycled materials may be used.

  The resin composition of the cap 20 can contain a chemical. Examples of the chemical include an antioxidant, a colorant, and a processing aid. The specifications of the cap 20 and the like are taken into consideration, and an optimal chemical is blended into the resin composition in an optimal amount.

  Below, the manufacturing method of the hinge cap 20 which concerns on this invention is shown.

  In the cap 20, the “flangeless cap 34” and the flange 30 are manufactured separately. A mold for manufacturing the flangeless cap 34 and a mold for manufacturing the flange 30 are prepared.

  The flangeless cap 34 is formed by heating and pressurizing the resin composition in a mold (not shown) of the flangeless cap 34. This mold is provided with a cavity. The shape of the cavity is equivalent to the shape of the flangeless cap 34. The resin composition is put into the cavity of the flangeless cap 34. At the time of charging, this mold is heated. The resin composition is heated and pressurized in the cavity. The resin composition flows by heating and pressurization. The resin composition is pressed against the mold cavity surface of the flangeless cap 34. The mold is cooled. Thereby, a resin composition solidifies and the cap 34 without a flange is obtained. After cooling, the flangeless cap 34 is removed from the mold.

  The manufacturing method of the flange 30 is also the same as described above. The flange 30 is formed by heating and pressurizing the resin composition in a mold (not shown) of the flange 30. This mold is provided with a cavity. The shape of this cavity is equivalent to the shape of the flange 30. The resin composition is put into the cavity of the flange 30. At the time of charging, these molds are heated. The resin composition is heated and pressurized in the cavity. The resin composition flows by heating and pressurization. The resin composition is pressed against the mold cavity surface of the flange 30. The mold is cooled. Thereby, the resin composition is solidified and the flange 30 is obtained. After cooling, the flange 30 is removed from the mold.

  FIG. 6A is a cross-sectional view showing a state of the flangeless cap 34 immediately after being taken out of the mold. FIG. 6B is a cross-sectional view showing a state of the flange 30 immediately after being taken out from the mold. As shown, the flangeless cap 34 is molded with the lid open. The cavity of the mold used for forming the flangeless cap 34 is configured in the form shown in 6 (a). The cavity of the mold used for forming the flange 30 is configured in the form shown in FIG.

  The flangeless cap 34 and the flange 30 taken out from each mold are fitted in the manner described above. Thereby, the hinge cap 20 is obtained.

  Hereinafter, the function and effect of the present invention will be described.

  As shown in FIG. 6A, the flangeless cap 34 does not include the flange 30 protruding from the main body 28, so that the flange 30 and the hinge 26 overlap in the vertical direction like a conventional hinge cap. There is nothing. In other words, the undercut is not formed in the flangeless cap 34. As shown in FIG. 6B, the flange 30 is not formed with an undercut. The flangeless cap 34 and the flange 30 are excellent in the removal property from the mold. In addition, the removed flangeless cap 34 and the flange 30 are easily integrated by fitting. The hinge cap 20 is excellent in productivity.

  The hinge cap 20 prevents excessive deformation when the flangeless cap 34 and the flange 30 are taken out from the respective molds. With this hinge cap 20, a high-quality cap can be stably produced.

  The hinge cap 20 does not require a complicated configuration of the mold in consideration of the removal property from the mold. The hinge cap 20 can contribute to a reduction in production cost. Since the mold can be configured with a small number of parts, the maintenance of the mold is easy.

  In this hinge cap 20, since an undercut is not formed, it is not necessary to provide a notch in the flange 30. The hinge cap 20 does not impair the appearance of the container. If this hinge cap 20 is used, a container excellent in aesthetics can be obtained. Moreover, since the hinge cap 20 has no notch, the container provided with the hinge cap 20 is not caught by other objects. This hinge cap 20 does not impair the ease of handling of the container.

  Due to the various requirements for the design of the container, the cap lid takes various shapes. In addition, various patterns and characters are engraved on the upper surface of the lid for decoration and to indicate manufacturers and products. In the hinge cap 20 according to the present invention, the lid 24 having these shapes, patterns, and characters can be created simply by changing the mold for the flange 30. On the other hand, the body 22 of the cap 20 has a substantially fixed shape depending on the size of the bottle. For this reason, the mold of the flangeless cap 34 can be commonly used in various products. In the hinge cap 20, it is not necessary to create a mold of the flangeless cap 34 for each product on which the cap 20 is mounted. Thereby, the hinge cap 20 corresponding to various products can be produced inexpensively. The hinge cap 20 according to the present invention contributes to cost reduction when the container is developed.

  FIG. 7 shows the use state of the cap 20. The cap 20 is provided in a container such as a shampoo from the beginning of sales. Alternatively, when the remaining amount of shampoo or the like is reduced, a dispenser or a normal cap is replaced with the hinge cap 20. As shown in FIG. 7, the container 52 is placed on the floor surface with the flange 30 of the cap 20 facing downward.

  In the cap 20, the outer diameter of the flange 30 is wider than the outer diameter of the body 22, so that the container 52 has excellent stationary stability when turned upside down. According to the cap 20, the state in which the container 52 is turned upside down is stably maintained, so that the liquid accumulated on the bottom of the bottle 54 of the container 52 hangs down by its own weight and accumulates in the cap 20 portion. For this reason, as soon as the user removes the lid 24 of the cap 20, the liquid is discharged from the spout. The user does not remember the trouble of discharging the liquid. The cap 20 can contribute to the use up of the liquid.

  In FIG. 7, the double arrow line WA represents the maximum width of the lid 24. A double arrow line WB represents the maximum width of the body 22. The ratio (WA / WB) of the maximum width WA of the lid 24 to the maximum width WB of the body 22 is 1.01 or more and 3.00 or less. By setting this ratio (WA / WB) to 1.01 or more, the hinge cap 20 can contribute to the stationary stability when the container 52 is turned upside down. In this respect, the ratio (WA / WB) is more preferably equal to or greater than 1.05 and particularly preferably equal to or greater than 1.10. By setting this ratio (WA / WB) to be equal to or less than 3.00, it is possible to reduce the occupation area when the container 52 is turned upside down and left standing. In this respect, the ratio (WA / WB) is more preferably equal to or less than 2.90 and particularly preferably equal to or less than 2.80.

  FIG. 8 shows a hinge cap 60 of a container for high viscosity liquid according to the second embodiment of the present invention. The cap 60 includes a body 62, a lid 64, and a hinge 66. The lid 64 includes a main body 68 and a flange 70. The cap 60 has the same configuration as the cap 20 of FIG. 1 except for the method of fitting the main body 68 of the lid 64 and the flange 70.

  In the lid 64 of the hinge cap 60, the main body 68 and the flange 70 are integrated by fitting and coupling. FIG. 8 shows a state before the flange 70 is fitted to the main body 68 of the lid 64. Here, the cap 60 including the lid 64 before the flange 70 is fitted is referred to as a “flangeless cap 72”.

  As shown in FIG. 8, the flange 70 includes a convex portion 74 on its lower surface. The convex portion 74 has a cylindrical shape. Four first protrusions 76 are provided on the outer peripheral surface of the convex portion 74. Each first protrusion 76 extends in the circumferential direction. These protrusions are aligned in the vertical direction. Although not shown in the drawing, R1 represents the distance from the center O of the cylinder to the radially outer end of the first protrusion 76. Although not shown in the figure, RF represents a radial distance from the center O to the outer peripheral surface of the cylinder. An arrow L1 is the vertical distance from the tip 78 of the convex portion 74 to the upper end of the first protrusion 76. A third protrusion 80 extending in the vertical direction is provided on the outer peripheral surface of the convex portion 74. The third protrusion 80 extends from the tip 78 of the protrusion 74 to the root.

  As shown in FIG. 8, the main body 68 has a recess 82 on its upper surface. The recess 82 has a cylindrical shape. Four second protrusions 84 are provided on the inner peripheral surface of the recess 82. Each of the second protrusions 84 extends in the circumferential direction. These protrusions are aligned in the vertical direction. Although not shown in the drawing, R2 represents the distance from the center O of the cylinder to the radially inner end of the second protrusion 84. Although not shown in the figure, RB represents a radial distance from the center O to the inner peripheral surface of the cylinder. In FIG. 8, the arrow L <b> 2 is the vertical distance from the bottom surface 88 of the recess 82 to the lower end of the second protrusion 84. Further, a groove 86 extending in the vertical direction is provided on the outer peripheral surface of the recess 82. The groove 86 extends from the bottom surface 88 of the recess 82 to the surface.

  Here, the above-mentioned distance RF is smaller than the distance RB. In other words, the outer diameter of the convex portion 74 is smaller than the inner diameter of the concave portion 82. Further, the distance R1 is larger than the distance R2. The third projecting portion 80 is formed in a size that fits into the groove 86. Furthermore, when the convex part 74 and the recessed part 82 are overlapped so that the position of the third projecting part 80 and the position of the groove 86 are matched, the first projecting part 76 of the convex part 74 and the second projecting part 84 of the recessed part 82 are It is provided at an overlapping position when viewed from above the cap 60. The distances L1 and L2 are the same value.

  In order to fit the flange 70 to the main body 68, the positions of the third protrusion 80 and the groove 86 are aligned, and the convex portion 74 of the flange 70 is pressed against the concave portion 82 of the main body 68. Since the distance RB is larger than the distance RF, the convex portion 74 enters the concave portion 82 partway. Since the distance R <b> 1 is greater than the distance R <b> 2, the first protrusion 76 contacts the second protrusion 84. Here, when the convex portion 74 is further pressed, the convex portion 74 is deformed inward in the radial direction. In other words, the convex portion 74 is deformed in a direction in which the distance R1 is reduced. Thereby, the convex portion 74 is further pushed into the concave portion 82. When the first projecting portion 76 is pushed beyond the second projecting portion 84, the deformation of the projecting portion 74 is restored. By this restoration, the distance R1 returns to the original value. Thereby, the convex part 74 does not come out of the concave part 82. The first protrusion 76 and the second protrusion 84 are engaged with each other. Since the distances L1 and L2 are the same, the tip 78 of the convex portion 74 just contacts the bottom surface 88 of the concave portion 82 at this time. The convex portion 74 does not slide in the vertical direction with respect to the concave portion 82. Further, since the third protrusion 80 is fitted in the groove 86, the convex portion 74 does not rotate in the circumferential direction with respect to the concave portion 82. Thereby, the flange 70 is fitted to the main body 68. The flange 70 and the main body 68 are integrated.

  The number of the first protrusions 76 and the second protrusions 84 is not limited to four. These may rotate in the circumferential direction. The number of the third projecting portions 80 and the number of grooves 86 is not necessarily one. These shapes and numbers are appropriately changed depending on the sizes and shapes of the main body 68 and the flange 70.

  Hereinafter, the function and effect of the present invention will be described.

  In this cap 60, the flangeless cap 72 and the flange 70 are manufactured separately. A mold for manufacturing the flangeless cap 72 and a mold for manufacturing the flange 70 are prepared. Since this flangeless cap 72 does not include the flange 70 protruding from the main body 68, an undercut is not formed. This flange 70 is also not formed with an undercut. The flangeless cap 72 and the flange 70 are excellent in the removal property from the mold. In addition, the removed flangeless cap 72 and the flange 70 are easily integrated by fitting.

Moreover, since the hinge cap 60 is not cut out, the container provided with the hinge cap 60 is not caught by other objects. This hinge cap 60 does not impair the ease of handling of the container.

  Due to the various requirements for the design of the container, the cap lid takes various shapes. In addition, various patterns and characters are engraved on the upper surface of the lid for decoration and to indicate manufacturers and products. In the hinge cap 60 according to the present invention, the lid 64 having these shapes, patterns, and characters can be created simply by changing the mold for the flange 70. On the other hand, the body 62 of the cap 60 has a substantially fixed shape depending on the size of the bottle. For this reason, the mold of the cap 72 without a flange can be commonly used in various products. In the hinge cap 60, it is not necessary to create a mold of the flangeless cap 72 for each product on which the cap 60 is mounted. Thereby, the hinge cap 60 corresponding to various products can be produced inexpensively. The hinge cap 60 according to the present invention contributes to cost reduction when the container is developed.

  In this cap 60, since the outer diameter of the flange 70 is wider than the outer diameter of the body 62, the container provided with this cap 60 is excellent in the stationary stability when turned upside down. According to the cap 60, the state in which the container is turned upside down is stably maintained, so that the liquid accumulated at the bottom of the bottle of the container hangs down by its own weight and accumulates in the portion of the cap 60. For this reason, as soon as the user removes the lid 64 of the cap 60, the liquid is discharged from the spout. The user does not remember the trouble of discharging the liquid. The cap 60 can contribute to the use up of the liquid.
