  • 2. Description of the Related Art
  • Generally, in a bottle in which a space accommodating a content is lengthily in a length direction and have a narrow inlet, the inlet thereof is designed to be openable and closeable by a cap member. In particular, the cap member includes an outer cap 3 openly and closely coupled to the inlet of the bottle 1 to seal the coupled inlet, an inner cap 2 forming a small hole 2 a for preventing a liquefied content from being discharged in large as shown in FIGS. 1 and 2. However, a outside air enters an inner part of the bottle 1 through the small hole 2 a because a vacuum in the inner space a of the bottle become larger than that in an outside space, that is, a vacuum pressure of the inner space of the bottle become larger than an atmospheric pressure.
  • That is, when the inner space a of the bottle becomes the same atmospheric pressure as the outside space b, it is possible to discharge the content of the bottle, and thus a volume of the inner space increases by the discharged amount to be a vacuum pressure, so that an operation moving air from the outer space b is repeatedly occurs.
  • Therefore, the content can not be discharged quickly due to a repetitive operation of discharge of the content and an inflow of the outside air through one a small hole 2 a and pouring the content quantitatively is obstructed due to a air bubble being produced within the bottle.
  • Even though the bottle is tilted to discharge the content, a residual content remains between the inner cap 2 and the bottle 1.
  • In order to discharge the residual content, it is disadvantage that the inner cap 2 should be separated.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • A stopper assembly of an embodiment of the present invention is to an improved stopper to prevent a sloshing of an it's liquefied content when a bottle is tilted, to allow a predetermined amount of the content to be poured and to allow the content to be easily discharged.
  • Referring to FIGS. 3 to 6 showing a stopper assembly of the present embodiment of the present invention, the stopper assembly includes an inner cap 20 coupled to an exiting port of the bottle 10 and an outer cap 30 openablely and closablely coupled to an outer side of the inner cap 20 to seal an inlet of the bottle. A male screw is formed at an outer peripheral surface of the inlet of the bottle 10 and a female screw threaded with the male screw is formed at the inner peripheral surface of the outer cap 30.
  • Referring to FIGS. 4 and 6, the inner cap 20 includes a cylindrical body 21 coupled to the inlet of the bottle 10 and a slope 22 a extending to the upper side thereof toward the center thereof from an edge of a lower end section of the body 21 and a protrusion 22 forming a plurality exit holes 22 b is around the slope 22 a.
  • Substantially, the protrusion 22 is in a truncated conical shape, wherein the truncated section 22 d is closed as shown to prevent a phenomenon in which the content of the bottle is poured to be discharged when the bottle is tilted to discharge the content.
  • The exit hole 22 b is lengthily formed from the lower end section of the slope 22 a to the upper end section thereof and a protrusion 22 c protruding from the edge of the lower end section of the inlet hole 22 b is formed. The protrusion 22 c is formed at every exit hole 22 b.
  • In addition, the inner cap 20 is made of a synthetic resin capable of an elastic deformation and the edge of the upper end section of the body is formed with the outwardly bent elastic piece 21 b.
  • The inner surface of the outer cap 30 is formed with the annular sealing rib 31 coupled to the inner peripheral surface of the upper end section of the body 21 and the circle sealing jaw 32 supporting the elastic piece 21 b. That is, the elastic piece 21 b is pressed in between the seal rib 31 and the seal jaw 32 and the sealing rib 31 is inserted into the inner peripheral surface of the inlet of the bottle 10 to seal the inlet of the bottle.
  • The inner peripheral surface of the inlet of the bottle 10 is formed with the concave groove 11 and the outer peripheral surface of the lower end section of the body 21 is formed with the convex section 21 c to be resiliently coupled and disconnected to the concave groove 11. In this case, the inner cap 20 is resiliently coupled to the inlet of the bottle 10 to prevent the inner cap 20 from being separated by a pressure of the content when the bottle 10 is tilted to discharge the content.

  • It is destroyed that a surface tension of the residual content 101 between the inner peripheral surfaces bottle 10 and the edge of the lower end section of the inner cap 20 by forming the protrusion 22 c in the lower end section of the inner cap 20, so that the residual content 101 is smoothly discharged.
  • In addition, the upper end section of the inner cap 20 is formed with the elastic piece 21 b and the outer cap 30 is formed with the sealing rib 31 and the sealing jaw 32 to provide an improved reliability of the sealing.
  • In addition, the inner peripheral surface of the inlet of the bottle 10 is formed with the concave groove 11 and the inner cap 20 is formed with the convex section 21 c to prevent the inner cap 20 from being deviated from the bottle 10 when the bottle is tilted to discharge the content.
  • A stopper assembly of the present invention is to prevent a sloshing of a liquefied content when a bottle is tilted to allow a predetermined amount of the content to be poured and to allow the content to be easily discharged.
  • In a stopper assembly of the present invention, when a bottle is tilted to discharge its liquefied content by forming a plurality of an exiting hole in an inner cap, the content is discharged through an outlet hole disposed at the outlet thereof and at the same time, air of the outside disposed at the upper section thereof flows in the bottle through the exiting hole disposed the upper section thereof, so that the discharge of the content is smoothly discharged without a sloshing of the content, thereby a predetermined amount of a content is discharged easy.
  • Furthermore, it is destroyed that surface tension of the content remained between the edge of the lower end section of the inner cap and the inner peripheral surface of the bottle by forming a protrusion in a lower end section of the inner cap to allow a smooth discharge of the residual content.
  • In addition, the upper end section of the inner cap is formed with the elastic piece and the outer cap to improve the reliability of the seal is formed with the sealing rib and the sealing jaw.
  • When the bottle is tilted to discharge the content under the condition that the inner peripheral surface of the inlet of the bottle is formed with the concave groove is the inner cap is formed with and the convex section, a combined state of the inner cap keeps stable.
