Definitions

  • the present invention relates to a hand-operated dropper configured to suction and discharge a predetermined amount of liquid type content upon pressing an elastic button, and, more particularly, to a hand-operated dropper including a housing for containing content, a housing cap for hermetically sealing an internal space of the housing from the outside, a tube for suctioning content from the housing, an elastic button hermetically coupled to the upper end of the tube, and a closure coupled to the housing cap while surrounding the outside of the elastic button in such a manner that opposite sides of the elastic button are exposed to the outside.
  • a hand-operated pump has been normally used in cosmetics containers that discharge a predetermined amount of liquid type content, such as oil and emulsion, each time because of its convenience.
  • a hand-operated dropper has been widely used in cosmetics containers and medicine containers because of its characteristics that a predetermined amount of content can be easily discharged each time by the hand-operated dropper while the content is stored in the container, and technology related to the hand-operated dropper has been continuously developed.
  • a conventional hand-operated dropper is generally configured in a structure in which an assembly of an elastic button and a tube coupled to each other in the same manner as a Pasteur pipette is mounted at the upper end of a housing containing content.
  • the content from the housing is suctioned into the tube, and the suctioned content is discharged out of the housing at a desired position.
  • the present invention has been made to solve the above problems, and other technical problems that have yet to be resolved.
  • a hand-operated dropper configured to suction and discharge a predetermined amount of liquid type content upon pressing an elastic button
  • the hand-operated dropper including (a) a housing, forming the external appearance of the dropper, for containing content, (b) a housing cap for hermetically sealing an internal space of the housing from the outside, (c) a tube coupled to an elastic button for suctioning content from the housing, (d) the elastic button hermetically coupled to the upper end of the tube, the elastic button being also coupled to the housing cap, and (e) a closure coupled to the housing cap while surrounding the outside of the elastic button in such a manner that opposite sides of the elastic button are exposed to the outside for suctioning a predetermined amount of content while protecting the elastic button from external force.
  • the elastic button when the elastic button is pressed, the elastic button is deformed. At this time, air or content present in the elastic button and the tube is discharged through the lower end of the tube. On the other hand, when the force applied to the elastic button is released, the elastic button returns to its original state due to elastic force thereof. At this time, internal pressure of the elastic button and the tube is lowered, with the result that a predetermined amount of liquid type content from the housing is introduced into the tube.
  • the closure is coupled to the housing cap in a structure to surround the outside of the elastic button, and therefore, it is possible for the closure to prevent the elastic button from being arbitrarily pressed due to external force and, in addition, to restrict the pressed position and deformed size of the elastic button upon pressing the elastic button or upon releasing the force applied to the elastic button. Consequently, it is possible to suction a predetermined amount of content and to discharge the suctioned content to a desired position.
  • a unique shape of the closure surrounding the outside of the elastic button may provide the hand-operated dropper with an aesthetically pleasing appearance.
  • the closure may be configured in an arch-shaped structure in vertical section. Therefore, it is possible for the closure to prevent the elastic button from being pressed due to falling of the dropper or unexpected application of external force to the dropper. In addition, the closure exhibits a predetermined strength, and therefore, it is possible for the closure to minimize the damage to the elastic button.
  • the exposed shape of the closure is not particularly restricted as long as it is possible for a user to easily press exposed regions of the elastic button using fingers.
  • the closure may be exposed in an elliptical shape in vertical section.
  • opposite sides of the closure are smoothly cut into an elliptical shape such that the opposite sides of the closure are exposed to the outside. Therefore, it is possible for a user to easily press the exposed sides of the elastic button using fingers.
  • the tube is configured in a hollow tube shape for suctioning and containing content.
  • the tube may have a relatively small inner diameter at a region adjacent to the lower end thereof for efficiently suctioning content.
  • the tube and the elastic button are coupled to each other.
  • This coupling may be achieved in the following manner.
  • the tube may be provided at the outer circumference of the upper end thereof with an annular protrusion extending outward
  • the elastic button may be provided at the lower part of the inner circumference thereof with a coupling groove corresponding to the annular protrusion
  • coupling between the tube and the elastic button may be achieved by the insertion of the annular protrusion of the tube into the coupling groove of the elastic button.
  • the coupling between the elastic button and the housing cap may be achieved in the following manner.
  • the elastic button may be provided at the outer circumference of the lower part thereof with a depressed groove
  • the housing cap may be provided at the inner circumference of the upper part thereof with a protrusion corresponding to the depressed groove
  • coupling between the elastic button and the housing cap may be achieved by the engagement between the protrusion of the housing cap and the depressed groove of the elastic button when the elastic button is inserted downward into the housing cap.
  • the coupling between the closure and the housing cap may be achieved through various molding processes as needed.
  • the coupling between the closure and the housing cap may be achieved by undercuts.
  • undercuts indicate parts, such as holes, protrusions, or depressions, of a molded product that cannot be removed by a motion carried out in the direction in which an injection mold is opened in terms of function or usage of the molded product.
  • An undercut formed at the inside of the molded produced is referred to as an inside undercut, and an undercut formed at the outside of the molded produced is referred to as an outside undercut.
  • the coupling between the housing and the housing cap may be achieved, for example, in a screw type structure that is capable of easily performing the engagement and disengagement between the housing and the housing cap and preventing content in the housing from being discharged out of the dropper.
  • the closure may be made of Surlyn, polycarbonate, acrylic resin, or metal, which exhibits a predetermined strength or elasticity
  • the housing cap may be made of polypropylene (PP) or metal.
  • Surlyn is a styrene acrylonitrile compound resin, which exhibits high elasticity and chemical resistance. Therefore, Surlyn is particularly suitable for a material of the closure.
  • FIG. 1 is a perspective view typically illustrating a hand-operated dropper according to an embodiment of the present invention
  • FIG. 2 is a perspective view typically illustrating a structure in which a housing is separated from the hand-operated dropper of FIG. 1 .
  • a hand-operated dropper 100 includes a housing 110 for containing 15 to 20 ml of content, a housing cap 120 for hermetically sealing the internal space of the housing 110, a tube 130 coupled to an elastic button 140 for suctioning content from the housing 110, the elastic button 140 hermetically coupled to the upper end of the tube 130, the elastic button 140 being also coupled to the housing cap 120, and a closure 150 coupled to the housing cap 120 for surrounding the outside of the elastic button 140.
  • the housing 110 is a hollow type container for containing liquid type content.
  • the upper end of the housing 110 is open.
  • the housing cap 120 is coupled to the upper part of the housing 110 for hermetically sealing the internal space of the housing 110 from the outside.
  • the coupling between the housing 110 and the housing cap 120 may be achieved in various manners.
  • a screw thread may be formed at the outside of an upper end protrusion part of the housing 110, and a screw groove corresponding to the screw thread may be formed at the inside of the housing cap 120.
  • the housing 110 and the housing cap 120 may be coupled to each other in a vertical engagement and disengagement manner, by which the coupling and separation between the housing 110 and the housing cap 120 may be much more easily achieved.
  • the elastic button 140 is formed of rubber exhibiting high elasticity.
  • the lower end of the elastic button 140 and the upper end of the tube 130 are coupled to each other in a hermetically sealed structure.
  • the closure 150 is coupled to the housing cap 120 while surrounding the outside of the elastic button 140 in such a manner that opposite sides of the elastic button 140 are exposed to the outside for suctioning a predetermined amount of content while protecting the elastic button 140 from external force.
  • FIG. 3 is a side view typically illustrating the hand-operated dropper of FIG. 1 .
  • the closure 150 is configured in an arch-shaped structure in vertical section corresponding to the outside of the elastic button 140. Also, the closure 150 is cut out in an elliptical shape 152 such that each side of the elastic button 140 is exposed to the outside. Therefore, it is possible for a user to easily press the exposed regions of the elastic button 140 at the sides thereof using fingers.
  • FIG. 4 is a vertical sectional view typically illustrating the coupling between the elastic button and the tube.
  • annular protrusion 134 is formed at the outer circumference of the upper end of the tube 130 such that the annular protrusion 134 extends outward, and a coupling groove 144 is formed at the lower part of the inner circumference of the elastic button 140.
  • the annular protrusion 134 of the tube 130 is inserted into the coupling groove 144 of the elastic button 140, thereby achieving the coupling between the tube 130 and the elastic button 140.
  • the tube 130 has a relatively small inner diameter at a region 136 adjacent to the lower end thereof for efficiently suctioning liquid type content from the housing 110 (see FIG. 1 ) and preventing the content from being discharged in a state in which the elastic button 140 is not pressed.
  • FIG. 5 is a front see-through view typically illustrating the hand-operated dropper of FIG. 1 .
  • a depressed groove 142 is formed at the outer circumference of the lower part of the elastic button 140, and a protrusion 122 corresponding to the depressed groove 142 of the elastic button 140 is formed at the inner circumference of the upper part of the housing cap 120.
  • an outside undercut 126 is formed at the upper end of the housing cap 120 in the lateral direction, and an inside undercut 156 corresponding to the outside undercut 126 of the housing cap 120 is formed at the lower end of the closure 150. Consequently, the coupling between the housing cap 120 and the closure 150 is achieved by the undercuts.
  • the housing 110 and the housing cap 120 are coupled to each other in a screw type structure 115, which provides high sealability, to prevent content in the housing 110 from being discharged to the outside.
  • the hand-operated dropper according to the present invention is configured such that the elastic button is prevented from being arbitrarily pressed by external force, a predetermined amount of content is suctioned upon pressing the elastic button, and the suctioned content is discharged upon releasing the force applied to the elastic button, greatly improving convenience and reliability.
