Definitions

  • the present invention relates to a container comprising a cover, a cup and an annular member.
  • the present invention also relates to a cosmetic package including said container.
  • Foundation liquid is widely used in the field of a cosmetic.
  • a sponge is used for absorbing and storing the liquid foundation.
  • the sponge is steeped with the liquid foundation, and is placed in a cup located within a base of the container. The user then gently touches and taps the sponge by an applicator to collect the liquid foundation, and then applies the liquid foundation onto the skin.
  • the cup is provided with an annular stop ring, which prevents the sponge from falling out of the cup when the container is opened.
  • One of the aims of the present invention is therefore to provide a container comprising a cover, a cup and an annular member which may address at least the problems mentioned above.
  • the annular member is a ring formed by bi-injection molding.
  • the bi-injection molding is also referred to as two-color injection molding or double injection molding.
  • the bi-injection molded ring according to the present invention simultaneously has two functions: the ring is used as an annular stop ring (for example made of PP) to prevent the sponge from falling out of the cup; and the ring is also used as an annular seal ring (for example made of TPE) to form a seal between the cover and the cup and thereby to prevent the liquid foundation from drying.
  • annular stop ring for example made of PP
  • annular seal ring for example made of TPE
  • a container comprising a cover, a cup and an annular member for said container, the annular member includes a stop ring and a seal ring.
  • the stop ring includes a ring body and a stopper extending from the ring body towards the center of the annular member.
  • the stop ring and the seal ring are formed in one piece by bi-injection molding.
  • the seal ring may have a first side and a second side, which are opposite from one another, and are intended to be abutted against by a cover and a cup of the container, respectively, such that the seal ring provides an airtight sealing between the cover and the cup.
  • the hardness of the stop ring may be higher than that of the seal ring.
  • the stop ring may be for example made from polypropylene (PP), and the seal ring may be for example made from thermoplastic elastomer (TPE).
  • PP polypropylene
  • TPE thermoplastic elastomer
  • the stopper of the stop ring may be in form of a flat ring lying in a horizontal plane.
  • the ring body of the stop ring includes a first part and a second part.
  • the first part is of a shape of a cylinder.
  • the stopper extends from an end of the cylinder towards the center of the annular member.
  • the second part is connected with the seal ring.
  • the second part of the ring body may include a transition section and a connection section.
  • the ring body and the seal ring may together delimit a annular groove.
  • An inner circumferential wall of the annular groove is formed by the first part of the ring body.
  • An outer circumferential wall of the annular groove is formed by the seal ring and the connection section of the second part of the ring body.
  • a bottom wall of the annular groove connecting the inner circumferential wall and the outer circumferential wall is formed by the transition section of the second part of the ring body.
  • the first part of the ring body of the stop ring may be intended to be fixed on a neck of the cup of the container.
  • the first part of the ring body of the stop ring may be provided with an inner protrusion
  • the neck of the cup of the container may be provided with an outer recess which has a shape complementary to that of the inner protrusion of the first part.
  • the interface between the seal ring and the stop ring may include a step.
  • the cover is provided with an engaging cylinder having an outer diameter which is larger than an inner diameter of the seal ring.
  • the cup is provided with an annular recess receiving the annular member and having an inner wall and an outer wall.
  • the first part of the ring body of the stop ring of the annular member is fixed on the inner wall of the annular recess.
  • the cup may be used for holding an absorber which may absorb and store volatile liquid.
  • the stopper of the stop ring of the annular member may extend inwardly beyond the opening of the cup, in order to prevent the absorber from falling out of the cup.
  • the absorber may be made from sponge or fabric.
  • the absorber may be used for absorbing and storing foundation liquid.
  • a cosmetic package including a shell assembly, an applicator and the container described above.
  • the container is placed in the shell assembly, and the applicator is placed on the cover of the container.
  • the annular member for the container is made at a lower cost, and can for example prevent the sponge or fabric from falling out of the cup, and can act as a seal between the cover and the cup to prevent the liquid foundation from drying.
  • FIGS. 1-3 show a preferred embodiment of a cosmetic package in accordance with the present invention.

  • the stop ring 110 includes a ring body 112 and a stopper 111.
  • the stopper 111 extends from the ring body 112 towards the center of the annular member 4, and extends inwardly beyond an opening of the cup 5.
  • a center hole of the stopper portion 111 has a diameter smaller than that of the absorber accommodated in the accommodation space 508 of the cup body 51, whereby the absorber can be prevented from falling out of the accommodation space 508.
  • the stopper 111 may be in form of a flat ring lying in a horizontal plane for example.
  • FIG. 6 shows a partial enlarged view of the inner container of the cosmetic package 10 in an assembled state.

  • the stop ring 110 and the seal ring 120 are formed in one piece by bi-injection molding, whereby the annular member 4 having both the stopping function and the sealing function is obtained in a low cost manner.
  • the sealing ring 120 and the stop ring 110 can also be connected by other manners, for example by adhesive bonding.
  • the interface between the seal ring 120 and the stop ring 110 includes a step 170, as shown in FIG. 6 . In this way, the seal ring 120 and the stop ring 110 can have a larger contact area, so that the connection between them will be stronger.

  • the first side 1201 and the second side 1202 are opposite from one another, and are intended to be abutted against by the cover 3 and the cup 5 of the container, respectively, such that the seal ring 120 provides an airtight sealing between the cover 3 and the cup 5.
  • the distance between the first side 1201 and the second side 1202, that is, the thickness of the seal ring 120 may be slightly larger than the distance between the engaging cylinder 311 of the cover 3 and the outer sleeve 53 in the closed state, so that the seal ring 120 will be squeezed and deformed when the cover 3 closes the cup 5, to provide a better airtight sealing performance.
  • the hardness of the stop ring 110 is higher than that of the seal ring 120.
  • the higher hardness of the stop ring 110 makes it easier to block the absorber stored within the cup 5, while the lower hardness of the seal ring 120 provides a good seal between the seal cover 3 and the cup 5.
