Definitions

  • the present invention relates to a container for storing cosmetics.
  • Patent Document 1 describes a container for storing cosmetics.
  • both the outer lid and the inner lid rotate up and down relative to the container body.
  • the outer lid is screwed onto the container body, and a gasket is attached to the underside of the inner lid.
  • the storage section is sealed with the gasket of the inner lid.
  • the outer lid is screwed on
  • the underside of the outer lid slides against the upper surface of the cylindrical part of the inner lid. Therefore, when the outer lid is screwed on, a rotational moment acts on the inner lid.
  • the inner lid just before the screwing is completed, the inner lid tries to rotate together with the outer lid.
  • the gasket is likely to twist circumferentially in the part of the inner lid opposite the hinge, which can easily reduce the sealing performance.
  • the objective of the present invention is to improve sealing performance.
  • the cosmetic container according to the present invention is a container for storing cosmetics, and includes a container body for storing cosmetics, a body threaded portion, and an opening on the top surface; an inner lid for closing the opening of the container body; a pressing member connected to the container body so as to rotate between a closed state located above the inner lid and an open state away from the inner lid; and an outer lid having a lid threaded portion that screws into the body threaded portion, relatively rotatably connected to the upper side of the pressing member, rotating together with the pressing member with respect to the container body, and screwed onto the container body when the pressing member is in the closed state, pressing the inner lid toward the opening of the container body via the pressing member.
  • a pressing member is interposed between the inner lid and the outer lid.
  • the pressing member rotates with the outer lid relative to the container body, and the outer lid is screwed onto the container body when the pressing member is in a closed state.
  • the outer lid presses the pressing member, which in turn presses the inner lid.
  • the pressing member attempts to rotate.
  • the pressing member is interposed between the outer lid and the inner lid, a rotational moment is unlikely to act on the inner lid even if the pressing member attempts to rotate. Therefore, the pressing force from the outer lid is smoothly transmitted to the inner lid via the pressing member.
  • the main body thread and the lid thread are multiple threads, and that a rotation regulating part is provided to regulate the rotation range of the outer lid relative to the clamping member so that the relative positional relationship in the circumferential direction between the outer lid and the clamping member is a specific positional relationship when the main body thread and the lid thread begin to mesh.
  • the point where the main body thread and the lid thread begin to mesh is called the meshing start point. If the main body thread and the lid thread are multiple threads, there are multiple meshing start points. For example, if the main body thread and the lid thread are double threads, there are two meshing start points.
  • the lid thread since a rotation regulating part is provided, the lid thread always begins to mesh with the main body thread at the same meshing start point.
  • the first meshing start point of the lid thread begins to mesh with the first meshing start point of the main body thread
  • the second meshing start point of the lid thread begins to mesh with the second meshing start point of the main body thread. That is, the first engagement start point of the lid threaded portion is prevented from beginning to engage with the second engagement start point of the body threaded portion. Therefore, the outer lid is always screwed onto the container body in the same circumferential direction and posture.
  • the pattern on the outer lid and the pattern on the container body are prevented from shifting 180 degrees in the circumferential direction, and the pattern on the outer lid and the pattern on the container body are in a specified circumferential positional relationship. Therefore, it is particularly effective in cases where the pattern on the outer lid and the pattern on the container body are joined vertically to form a single pattern.
  • an elastic portion that biases the outer lid in a direction away from the pressing member.
  • the free movement of the outer lid is suppressed.
  • the outer lid is less likely to vibrate against the pressing member, and the generation of noise due to vibration is also suppressed. This allows for a sense of luxury to be created.
  • the outer lid is less likely to rotate freely against the pressing member. In other words, the circumferential phase of the outer lid relative to the pressing member is less likely to change.
  • the outer lid is less likely to shift in position in the circumferential direction relative to the container body, making it easier to start screwing from the same meshing start point. Furthermore, since the elastic portion presses the outer lid, the inclination of the outer lid is suppressed, and the outer lid can be smoothly screwed into the container body. And since the outer lid is pressed by the elastic portion even during the process of screwing the outer lid into the container body, the user can rotate the outer lid with a moderate pushing force while feeling the biasing force or repulsive force of the elastic portion. Therefore, a smooth rotation feel of the outer lid is obtained, allowing for a sense of luxury to be created.
  • the elastic portion is integrally formed with the pressing member so as to press the outer lid.
  • the elastic portion may be a separate structure from the outer lid and the pressing member, but by forming the elastic portion integrally with the pressing member, it is easy to form the elastic portion. Furthermore, the elastic portion is less noticeable than in a structure in which the elastic portion is integrally formed with the outer lid.
  • the pressing member is provided with a spring piece as an elastic part that elastically deforms up and down, the spring piece being long along the circumferential direction of the body threaded part and the lid threaded part, with one end serving as a fulcrum and the other end elastically deforming up and down to press the outer lid, and it is preferable that the other end of the spring piece is positioned in the direction in which the outer lid is screwed into the container body relative to the one end of the spring piece.
  • the pressing member is provided with a spring piece as an elastic part that elastically deforms up and down, and it is preferable that the spring piece is long in the circumferential direction of the body threaded part and the lid threaded part, and that the central part elastically deforms up and down with both ends as fulcrums to press the outer lid.
  • the spring piece is less likely to get caught on the inner surface of the outer lid, so the outer lid can be screwed in smoothly and the spring piece elastically deforms smoothly.
  • both ends of the spring piece are continuous with other parts of the pressing member, the spring piece can elastically deform stably over a long period of time.
  • the pressing member has a hole penetrating from top to bottom, a spring piece is provided in the hole, and a mirror is attached to the underside of the pressing member, with the hole and spring piece being covered and hidden by the mirror.
  • the hole allows the spring piece to elastically deform smoothly up and down.
  • the spring piece can be easily formed by molding. Furthermore, because the hole and spring piece are hidden by the mirror, a good external appearance is obtained.
  • the underside of the pressing member is provided with a pressing surface portion on the outside of the mirror that presses the peripheral portion of the inner lid downward when in the closed state.
  • the mirror does not press the inner lid, but rather the pressing surface portion provided on the outside of the container of the mirror presses the inner lid.
  • the pressing surface portion presses the peripheral portion of the inner lid, the pressing force from the pressing member acts evenly on the entire inner lid, compared to a configuration in which the pressing member presses the center of the inner lid.
  • a protruding wall protruding upward is provided on the upper surface of the pressing member at a position corresponding to the upper side of the pressing surface portion, or a protruding wall protruding downward is provided on the lower surface of the outer lid at a position corresponding to the upper side of the pressing surface portion, and the outer lid presses the inner lid via the protruding wall and the pressing surface portion.
  • the pressing force of the outer lid acts effectively on the peripheral portion of the inner lid via the protruding wall and the pressing surface portion. Therefore, the opening of the container body can be tightly sealed by the inner lid.
  • the container body preferably comprises a replaceable inner container for storing cosmetics, a main container for holding the inner container, and a lower container for covering the main container from below, the main container having an inner lid support part for rotatably supporting the inner lid, and the lower container having an outer lid support part for rotatably supporting the pressing member.
  • the container can be used continuously by replacing the inner container for storing cosmetics with a new one.
  • the container body comprises the main container and the lower container, it becomes easy to separately support the inner lid and pressing member on the main container and the lower container, respectively. Therefore, the inner lid support part and the outer lid support part can be easily formed.
  • the outer lid support part is located below the body thread part, and the inner lid support part is located above the outer lid support part.
  • the pressing member has a plate portion that presses the inner lid in the closed state, an arm portion that extends from the plate portion toward the outer lid support portion, and a connecting portion that is provided at the lower end of the arm portion and connects to the outer lid support portion
  • the main container has an upper recess in the side portion of the main container where the main body screw portion is cut out
  • the lower container has a lower recess in the side portion of the lower container that is continuous with the lower side of the upper recess
  • the outer lid support portion is provided in the lower recess
  • the arm portion is inserted through the upper recess

  • Figures 15 to 17 show the outer lid 6 and the pressing member 5 as viewed from the pressing member 5 side. Note that the mirror 62 is omitted from Figures 15 and 17.
  • Figures 15 to 17 show the state when the outer lid 6 is screwed onto the container body 2 and the outer lid 6 is in the closed state.
  • the allowable range is 215 degrees.
  • the circumferential length (width) of the stopper 75 corresponds to 20 degrees. Therefore, the stopper 75 can move within an angular range of 195 degrees, which is 215 degrees minus 20 degrees.
  • the outer lid 6 can rotate within an angular range of 195 degrees
  • the movable range of the outer lid 6 relative to the pressing member 5 is 195 degrees.
  • the stopper 75 does not abut against the regulating wall 57. That is, the contact surface 76 on the closing side of the stopper 75 does not contact the regulating surface 58 on the closing side of the regulating wall 57, and there is a space of 5 degrees between the contact surface 76 on the closing side of the stopper 75 and the regulating surface 58 on the closing side of the regulating wall 57. Therefore, the outer lid 6 can be rotated another 5 degrees in the screw-in direction, i.e., counterclockwise in FIG. 17, but the 5 degrees are a rotation margin. In the state of FIG. 17, the packing 44 is pressed and the inner container 7 is sealed.
  • the outer lid 6 can be further tightened to the closing side.
  • the outer lid 6 when the outer lid 6 is removed from the container body 2, the outer lid 6 can be rotated to the closing side relative to the pressing member 5 until the contact surface 76 on the closing side of the stopper 75 contacts the regulating surface 58 on the closing side of the regulating wall 57.

  • the stopper 75 has not yet come into contact with the regulating surface 59 on the opening side of the regulating wall 57, and there is a space of 10 degrees between the abutment surface 77 on the opening side of the stopper 75 and the regulating surface 59 on the opening side of the regulating wall 57.
  • the screw is a double-thread screw, so the outer lid 6 can be removed from the container body 2 by rotating the outer lid 6 180 degrees to the open side. Conversely, the outer lid 6 can be rotated 180 degrees in the closing direction from the engagement start point 30 to achieve the closed state.
  • FIG. 18(c) shows the state in which the outer lid 6 has been rotated 10 degrees further in the open direction from the state in FIG. 18(b), with the opening side abutment surface 77 of the stopper 75 abutting against the opening side regulating surface 59 of the regulating wall 57. As the stopper 75 abuts against the regulating wall 57, the outer lid 6 cannot be rotated further in the open direction relative to the pressing member 5.
  • the pressing member 5 is interposed between the outer lid 6 and the inner lid 4, and the outer lid 6 presses the inner lid 4 via the pressing member 5. Therefore, when the outer lid 6 is tightened, a rotational moment is not likely to act on the inner lid 4, and the inner lid 4 is not likely to twist. This prevents the sealing performance of the inner container 7 from decreasing.
  • the downward pressing force of the outer lid 6 is transmitted to the plate portion 50 of the pressing member 5 via the protruding wall 63, and is transmitted to the inner lid side portion 43 of the inner lid 4 via the pressing surface portion 61.
  • the pressing force of the outer lid 6 is efficiently transmitted to the packing 44 via the pressing member 5 and the inner lid 4, so that the packing 44 is reliably compressed and the opening 10 is sealed.
  • the pressing force of the outer lid 6 is likely to act evenly around the entire circumference of the packing 44.
  • the rotation of the outer lid 6 is restricted by the stopper 75 and the restricting wall 57. Because the rotation of the outer lid 6 is restricted within a specified angle range, unnecessary rotation of the outer lid 6 is kept to a minimum when the open outer lid 6 is screwed onto the container body 2, and the outer lid 6 can be easily closed.
  • the outer lid 6 is always screwed in from the same meshing start point 30.
  • a pattern 80 may be provided on the container body 2, and a pattern 81 may be provided on the outer lid 6.
  • the pattern 80 on the container body 2 and the pattern 81 on the outer lid 6 may be integrated vertically to form one design. If the outer lid 6 is always screwed in from the same meshing start point 30, the pattern 81 on the outer lid 6 and the pattern 80 on the container body 2 will not be misaligned by 180 degrees in the closed state, and the circumferential position of the pattern 81 on the outer lid 6 and the circumferential position of the pattern 80 on the container body 2 will essentially match. As a result, a beautiful appearance is obtained.
  • the rotation regulating section is formed by the regulating wall 57 of the support tube 54 and the stopper 75 of the central support shaft 73, the rotation regulating section is easy to configure, and the rotation range can be easily and reliably regulated.
  • a stopper 75 may be provided on the support tube 54 and a restricting wall 57 may be provided on the central support shaft 73, or a rotation restricting portion may be provided on a portion other than the support tube 54 or the central support shaft 73.
  • the rotation of the outer lid 6 is restricted on both the closing side and the opening side, it is also possible to restrict only the rotation on the opening side, or only the rotation on the closing side. However, it is preferable to restrict at least the rotation on the opening side.
  • the spring piece 65 constantly presses against the outer lid 6. This prevents the outer lid 6 from loosening unintentionally, and the gasket 44 is kept compressed to maintain sealing force.
  • the spring piece 65 also presses against the outer lid 6 not only in the closed state but also in the open state. This limits free movement of the outer lid 6 relative to the retaining member 5 in the open state. This makes it less likely that the outer lid 6 will vibrate and make a rattling noise in the open state. As unintentional vibration and noise of the outer lid 6 are suppressed, a sense of luxury can be created.
  • the outer lid 6 is difficult to rotate relative to the pressing member 5 in the open state. In other words, when the outer lid 6 is removed from the container body 2, the outer lid 6 maintains almost the same circumferential orientation relative to the pressing member 5. Therefore, when closing the outer lid 6, the outer lid 6 can be screwed in immediately from the engagement start point.
  • the rotation range of the outer lid 6 is restricted by the rotation restriction part, but even if a rotation restriction part is not provided, the spring piece 65 presses the outer lid 6, making it difficult for the outer lid 6 to rotate relative to the pressing member 5 in the open state. Therefore, the outer lid 6 can be screwed in from the specified engagement start point 30.
  • the spring piece 65 presses the outer lid 6 upward, preventing the outer lid 6 from tilting or twisting, allowing the outer lid 6 to be screwed smoothly into the container body 2. Furthermore, even during opening and closing operations, the pressing force of the spring piece 65 acts on the outer lid 6, so the outer lid 6 can be rotated with a moderate pushing force while feeling the biasing force and repulsive force of the spring piece 65. As a result, the outer lid 6 is less likely to rattle, and a smooth rotation feel of the outer lid 6 is obtained, creating a luxurious feel. Even at the end of screwing the outer lid 6, the spring piece 65 is still pressing the outer lid 6, so the outer lid 6 can be securely fastened to the container body 2 without being overly screwed.
  • the outer lid 6 can be screwed in smoothly, and the spring piece 65 can be smoothly elastically deformed downward.
  • the pressing protrusion 66 on the other end of the spring piece 65 makes point contact with the outer lid 6, the sliding resistance between the outer lid 6 and the spring piece 65 is small, and the outer lid 6 can be smoothly rotated.
  • the mirror 62 on the underside of the plate portion 50 covers and conceals the punched holes 64, spring pieces 65, stoppers 75, and restricting walls 57. Therefore, when the outer lid 6 is viewed from below in the open state, the spring pieces 65 and other elements provided between the outer lid 6 and the plate portion 50 of the pressing member 5 are not visible. This provides a good external appearance and creates a sense of luxury.
  • the pressing surface portion 61 is provided on the radially outer side of the mirror 62, so the mirror 62 is less likely to become dirty or scratched.
  • the inner lid support shaft 32 and the outer lid support shaft 39 are distributed between the main container 8 and the lower container 9, respectively, so that the inner lid support shaft 32 and the outer lid support shaft 39 can be easily installed.

  • the knob 15 of the inner container 7 is located in the upper recess. Therefore, the knob 15 can be easily operated by inserting a finger into the upper recess 31, making it easy to replace the inner container 7. Because the knob 15 has an extension 15b, the knob 15 can be easily grasped when replacing the inner container 7, making the replacement even easier. Moreover, because the extension 15b is located radially inward of the arm 51 in the upper recess 31, the extension 15b can be easily stored.
