Definitions

  • the present disclosure relates to a cosmetic case, and in particular to an airtight loose powder case structure having a powder puff.
  • Cosmetics are usually contained in portable cosmetic cases.
  • Most traditional powder cases include a case body and a lid.
  • the case body is provided with an accommodation cavity for accommodating a cosmetic.
  • the lid is connected to the case body and is configured to unseal and seal the accommodation cavity .
  • the cosmetic can be used through simply opening the lid by a user.
  • the traditional powder cases suffer from poor airtightness. Since a volatile solvent is contained in the cosmetic, in case of the poor airtightness of the powder case, the volatile solvent in the cosmetic is volatilized gradually. Consequently, the cosmetic is hardened and deteriorated to cause a waste. Moreover, when loose powder is directly dipped for makeup, the powder is dipped unevenly and may float in the air, thus causing the uneven makeup and the cosmetic waste.
  • the present disclosure provides an airtight loose powder case structure having a powder puff to overcome the above defects.
  • the airtight loose powder case structure having a powder puff achieves desirable airtightness, can keep the airtightness effective for a long time, prevents a cosmetic from being hardened and deteriorated, and is carried and used conveniently.
  • An airtight loose powder case structure having a powder puff includes a base, an upper lid, an inner cup, and a powder puff, where the powder puff is provided in the inner cup; the inner cup is provided in the base; the upper lid overlays an opening of the base; the upper lid is configured to seal and unseal the opening of the base; screw threads matched with each other are respectively provided on the upper lid and the opening of the base, for example, the upper lid is provided with an inner screw thread, and the opening of the base is provided with an outer screw thread, such that the upper lid can seal and unseal the opening of the base; an inner lid is further provided; the inner lid is configured to seal and unseal an opening of the inner cup; the inner lid is located under the upper lid (the inner lid is not separated from the upper lid); the inner lid is configured to move freely relative to the upper lid in an axial direction; the inner lid is configured to rotate freely relative to the upper lid in a circumferential direction; a circle of seal
  • the upper lid When the upper lid is screwed to the opening of the base, the upper lid moves down, and the inner lid rotates together with the upper lid and moves down.
  • the seal ring abuts against the inner side of the inner cup, due to a frictional force between the seal ring and the inner side of the inner cup, the inner lid cannot rotate together with the upper lid.
  • the upper lid is further screwed and moves down, the inner lid moves down along the axial direction, and the seal ring can further press the inner side of the inner cup to attach with the inner cup desirably. In this way, desirable airtightness is achieved.
  • the seal ring does not rotate when pressed down. That is, there is basically no slip between the seal ring and the inner side of the inner cup. After long-term use, the seal ring is not damaged, and the airtightness can be kept effective all the time.
  • a circle of groove is formed at an inner side of the upper lid; a circle of protrusion is provided at an outer side of the inner lid; the protrusion is movably located in the groove (the inner lid is located on the upper lid and is not separated, provided that an outer diameter of the protrusion is slightly greater than an inner diameter of the groove); and in the axial direction of the inner lid, a height of the groove is greater than a height of the protrusion.
  • the inner lid is configured to move freely relative to the upper lid in the axial direction, and rotating freely relative to the upper lid in the circumferential direction.
  • the groove has a trumpet-shaped rabbet; an upper side of the protrusion is oblique for ease of assembly; and a lower side of the protrusion is horizontal so as not to fall out of the groove.
  • the seal ring in the axial direction of the inner lid, has a U-shaped section; a circle of shoulder is provided in the opening of the inner cup; a bottom of the U-shaped seal ring is configured to abut against the shoulder of the inner cup; and the powder puff is located in the inner cup within the shoulder.
  • a circle of downward clamping rabbet is formed at a periphery of the inner cup, and the clamping rabbet is clamped and sleeved on a periphery of the opening of the base. In this way, the inner cup is detachably clamped on the opening of the base.
  • the present disclosure has the following beneficial effects: Since the screw threads matched with each other are respectively provided on the upper lid and the opening of the base.
  • the upper lid is configured to seal and unseal the opening of the base.
  • the inner lid is configured to seal and unseal the opening of the inner cup.
  • the inner lid is located under the upper lid.
  • the inner lid is configured to move freely relative to the upper lid in an axial direction.
  • the inner lid is configured to rotate freely relative to the upper lid in a circumferential direction.
  • the circle of seal ring is provided under the inner lid.
  • the seal ring is configured to abut against the inner side of the inner cup.
  • the powder puff is located in the seal ring.
  • the upper lid When the upper lid is screwed to the opening of the base, the upper lid moves down, and the inner lid rotates together with the upper lid and moves down.
  • the seal ring abuts against the inner side of the inner cup, due to a frictional force between the seal ring and the inner side of the inner cup, the inner lid cannot rotate together with the upper lid.
  • the upper lid is further screwed and moves down, the inner lid moves down along the axial direction, and the seal ring can further press the inner side of the inner cup to attach with the inner cup desirably. In this way, desirable airtightness is achieved.
  • the seal ring does not rotate when pressed down. That is, there is basically no slip between the seal ring and the inner side of the inner cup.
  • the seal ring After long-term use, the seal ring is not damaged, and the airtightness can be kept effective all the time.
  • the present disclosure achieves the desirable airtightness, can keep the airtightness effective for a long time, prevents a cosmetic from being hardened and deteriorated, and is carried and used conveniently.
