The present disclosure relates to a dropper package for applying and dispensing a fluid product, such as cosmetic product, pharmaceutical products etc. More particularly, the present disclosure relates to a dropper package having an applicator tip for a controlled delivery of a fluid product onto the keratinous surface of the user.
In the personal and beauty care application space, dispensers are often used to dispense products used on a user's skin, such as make-up products, beauty enhancers, serums, and other liquids. In some instances, such products may be dispensed with a conventional bulb-dropper dispenser. Conventional bulb-droppers generally include a flexible bulb attached to one open end of a rigid tube. To use such a device, a user may squeeze the deformable bulb and insert the opposite open end of the rigid tube into a liquid or fluid product and release the deformable bulb. Upon release of the deformable bulb, a vacuum is formed, resulting in the drawing of liquid into the ridged tube. To dispense the liquid from the rigid tube, the user may again squeeze the deformable bulb, forcing the liquid or fluid out of the rigid tube and onto a desired surface such as the user's skin, a cloth, or other substrate. Conventional bulb-droppers have also been adapted for use with containers or bottles such that the deformable bulb-dropper also includes a collar capable of being attached to a container or bottle for storage and shipping.
Many of such dropper packages include an applicator attached to a tube for drawing product from the applicator and applying product to the user's skin, hair, etc. During use, the dropper squeezes.

Further, the applicator tip has a generally symmetrical shape body with respect to a median plane of symmetry and comprises the central through cavity which is delimited laterally by two lateral portions or branches and axially by a distal portion of the applicator tip and a proximal portion of the applicator tip joining the branches. The central through-cavity is elongated in shape and extends along the branches which are made of a rigid thermal material. A “median plane” of symmetry divides an element longitudinally into two equal and symmetrical parts.
According to yet another aspect of the present disclosure, the central through cavity has an elliptical shape. In a preferred embodiment, the central through-cavity formed on the applicator tip is oval or elliptical, and also helps in forming surface tension in fluid product dropped on the inner periphery of the applicator tip. In alternate embodiments, however, the central through cavity may have any other suitable shape and size, and surface finish desired for a given application of the fluid product unless the surface tension is broken when in contact with the user's skin during application.
Furthermore, the applicator tip comprises at least two main application faces i.e. a front application face and a back application face. Both the front application face and back application face are opposite to each other and are symmetrical in structure. Furthermore, the central through-cavity is open to the outside through both the front and back application faces. Both the front application face and back application face are elliptical and have convex outer surfaces. In alternate embodiments, however, the front and back applicator faces may have any other suitable shape and size, and surface finish desired for a given application. The convex outer surfaces of the back and front application faces enable precise massage of small or narrow areas of the user's keratinous surface such as upper lips, under eye, etc.
The front and back application faces are intended to come into contact with the skin during the use of the applicator tip, in order to apply the fluid product contained in the central through cavity. The central through cavity opens onto the front application face through a front opening and the central through cavity is open on the outside on the back application face by a back opening. The size of the front opening of the central through cavity is larger than that of the back opening, in particular at least by 20%. In an embodiment, the central through cavity is conical with an elliptical cross-section and wherein a depth of the central through cavity extends in a direction perpendicular to the longitudinal axis of the dropper package. In other words, the central through cavity is an elliptical cone-shaped cavity. The front opening and back opening of the central through cavity are both elliptical.

According to yet another aspect of the present disclosure, the connector includes an upper portion and a lower portion. The upper portion and the lower portion both are cylindrical. The upper portion has a diameter lesser than the diameter of the lower portion of the connector. The upper portion of the connector is coupled to a lower portion of the tube and the lower portion of the connector is coupled to an upper portion of the applicator tip. The connector is hollow that defines a channel to allow the fluid product to flow through it. The fluid product can flow in and discharge out from the longitudinal channel of the tube through the channel of the connector.
Further, the connector includes one coupling groove and one coupling protrusion, wherein the coupling groove is provided on an inner circumferential surface of the lower portion, and the coupling protrusion is provided on the outer peripheral surface of the upper portion of the connector. Additionally, both the coupling groove and protrusion can be constructed of any diameter and depth. Further, the connector may be of any shape or include various structures.
According to an aspect of the present disclosure, the applicator tip may be secured to the connector, for example, by a press-fit, snap-fit, adhesive, and/or engagement by one or more engagement features or by any other means of engagement known in the art. In an embodiment, the upper portion of the applicator tip includes at least one coupling protrusion that is received in the at least one coupling groove present on the inner circumferential surface of the lower portion of the connector, in order to snap couple the applicator tip with the connector.
According to another aspect of the present disclosure, the tube includes at least one coupling groove formed on an inner periphery near the proximal end portion of the tube. Further, the coupling protrusion present on the upper portion of the connector is received and fitted into the coupling groove of the tube for coupling the connector to the tube. In various embodiments, the connector may be secured to the tube by a press-fit, snap-fit, adhesive, and/or engagement by one or more engagement features or by any other means of engagement known in the art.
According to an aspect of the present disclosure, a series of channels is defined in an inner periphery of the dropper assembly. In an embodiment, a dispensing channel extending from one end to another end of the connector is in precise and through and through connection with the dispensing channel of the applicator tip. Further, both the dispensing channels of the applicator tip and the connector respectively are connected in such a manner that both the dispensing channels come in a straight longitudinal alignment and form a continuous channel for intake, storage, and discharge of the fluid product. Intake of the fluid product inside the dispensing channel as well as the release of the fluid product is done through the dispensing orifice. Further, the fluid product released from an orifice of the applicator tip is held within the central through cavity so that it can be applied to the skin of the user.
According to an aspect of the present disclosure, the push button is configured to moves axially along the longitudinal axis of the package between the highest position and the lowest position when a force is applied or released from the push button. In use, when the push button is pressed slowly towards its lowest position, it causes the deformable bulb to deform reducing the interior volume of the chamber of the deformable bulb and ready the dropper assembly for drawing fluid product out of the container body. Releasing the push button allows the chamber of the deformable bulb to return to its original volume and shape, drawing the fluid product into the dispensing orifice in the applicator tip and up into the channel in the tube through channels of the applicator tip and the connector respectively. To dispense the drawn-in product, when the channel of the tube is already filled with a predetermined quantity of fluid product, in that case, the push button is pressed slowly towards its lowest position, causing the deformable bulb to deform as a result the fluid product discharges out in a controlled manner from the dispensing orifice on the applicator tip. More particularly, when pressure is applied by the squeezing action to the deformable bulb, the fluid product in the tube is forced to dispense out through the orifice via dispensing channels, and for application to the user's skin. The fluid product released from the dispensing orifice comes directly onto the inner periphery of the applicator tip, which surrounds the central through cavity and creates a surface tension to prevent the fluid from falling and wasting. When the user's skin touches the applicator tip it breaks the surface tension and releases the fluid product held by the surface tension onto the user's keratinous surface.
In alternate embodiment, the applicator tip may be directly connected to the tube without the use of an intermediate connector.
According to an aspect of the present disclosure, the container body that defines a reservoir for filling with fluid may be made of a rigid material like glass, metal, hard plastic, or any other material known in the art. However, in alternate embodiments, the container body is made of glass material. The container body material is non-reactive with the fluid product stored in the reservoir. In other implementations, the container body may be made of virtually any other material that is non-reactive or resistant to the fluid product being dispensed, such as various metals, plastics, glass, composites, or the like.
According to an aspect of the present disclosure, the cosmetic package is of an elongated cylindrical configuration. However, in alternate embodiments, the cosmetic package may be of an elongated square, polygonal configuration, oval, triangular, heart, or any other configuration known in the art.
According to an embodiment, the cap may be made of a rigid material like metal, hard plastic, or any other material known in the art. However, in alternate embodiments, the cap may be made of a rigid thermoplastic material like; acrylonitrile-butadiene-styrene (ABS); polyethylene (PE); polypropylene (PP), or any other material known in the art.
