The present invention discloses an eco-friendly recyclable dropper, comprising a pressing portion and a pipette, wherein a bottom of the pressing portion is wrapped around a top of the pipette, wherein a bottom inner wall of the pressing portion includes a concave groove, wherein a top outer wall of the pipette includes a corresponding convex circle, wherein the concave groove matches with the convex circle and become airtight based on the characteristics of both material, wherein the pressing portion is made of PE material, wherein the pipette is made of PP material. Since the pressing head is made of PE material or a mixture material of PE and PP, and the pipette is made of PP material, a combination of the pressing head and the pipette is better in airtightness comparing to prior arts using glass pipettes; furthermore, the design of the pressing head and the concave groove and the convex circle of the pipette provides better airtightness; the dropper and the bottle of this invention both used PP and PE material, which can be fully recycled and reused after using the liquid within, avoids environmental pollution and saves resources. The market of this invention is very wide and this invention has a breakthrough meaning in the dropper field.

A protector assembly for handling, storing and transporting donor tissue in a transfer pipette includes a distal cap and a proximal plug that are respectively engageable with opposite ends of the pipette. Structurally, the pipette includes a distally tapered fluid chamber which is in fluid communication with an extension tube. The distal cap is dimensioned for friction engagement with the fluid chamber of the pipette and it is formed with a plurality of vents to establish fluid communication through the vents with the fluid chamber. On the other hand, the proximal plug is dimensioned for a friction engagement with the extension tube to prevent leakage of solution from the fluid chamber of the pipette when the proximal plug is engaged with the pipette. In combination, an engagement of the protector assembly with a pipette holding a donor tissue will protect and preserve the donor tissue during handling and transport.

Disclosed is a dropper type cosmetic container. The dropper type cosmetic container includes a container body for containing a cosmetic material therein; a fixing member fixedly coupled to the container body and formed with a cylinder; an elevating member coupled to the fixing member to move up or down and formed with a synthetic resin elastic body; a dropper tube connected to the fixing member to suck and discharge the cosmetic material contained in the container body; a rotating member rotatably coupled to the fixing member; and a push button moving up or down together with the elevating member and having one side coupled to a piston, wherein a movement limiting protrusion is formed on one side of the elevating member, and a movement limiting hole is formed in one side of the push button, so that the movement limiting protrusion is coupled to the movement limiting hole, thereby limiting a movement section of the push button and a compression range of the elastic body.

A fluid dispenser having a reservoir (R) containing fluid (P) and air (A), the reservoir (R) forming an assembly opening (11); a fluid dispenser cannula (12) in communication with the reservoir (R); and an actuator member (2) engaged in the assembly opening (11), for supplying the dispenser cannula (13) with fluid (P). The actuator member (2) has a deformable membrane (23) that defines an outside face (231) forming a pusher (24), and an inside face (232) that is in contact with the air (A) of the reservoir (R), when the dispenser cannula (12) is in contact with the fluid (P) of the reservoir (R).

An apparatus for limiting pipette motion, the apparatus comprising: (1) a stand for controlling spatial positions; (2) a mechanism for temporally coupling the pipette with the stand; the orientation or the movement of the pipette being restricted by the stand as predetermined for (a) limiting the insertion depth of the pipette tips into sample containers, (b) restricting unwanted movements or rotations of the pipette, or (c) maintaining the desired alignments of the pipette tips with the sample containers. Methods of limiting pipette motion or rotation are also provided.

This invention relates to a packaging and distribution assembly (10) for a fluid product, of the type comprising: a storage member (22), comprising a tubular reservoir (40) able to receive a first fluid composition; a closed chamber (130) in communication with the tubular reservoir; and a pressurization member (24), able to move axially in such a way as to decrease a volume of said closed chamber. The closed chamber is sealed from the air in a deployed configuration of the storage and pressurization members, corresponding to a maximum volume of the closed chamber. The storage member (22) and the pressurization member (24) comprise means (76) for breaking the seal of the closed chamber in a compact configuration of said storage and pressurization members, said compact configuration corresponding to a minimum volume of the closed chamber.

A solution jetting device includes: a cylindrical member; a movable member that is movably fitted to a hollow portion of the cylindrical member; a first drive mechanism that moves the movable member; a first flow passage that connects a solution container, in which a solution containing a biological sample or containing a reagent to be reacted with a biological sample is contained, to the hollow portion; an openable and closable first on-off valve that is provided on the first flow passage; a jetting tool that jets the solution to an objective region; a second flow passage that connects the hollow portion to the jetting tool; an openable and closable second on-off valve that is provided on the second flow passage; a second drive mechanism as defined herein; and a control unit as defined herein.

A cosmetic container with an adjustable discharge quantity includes a container body, an inner cover, an outer cover, a button, a piston, and an elastic member. The upper part of the container body is provided with an opening. The inner wall of the inner cover is threadedly connected to the opening of the container body, and the inner cover extends upward to form an inner cylinder. A plurality of stepped grooves with different depths are arranged in parallel in a movement area of the outer wall of the inner cylinder. The lower end of the inner cover is hermetically connected to a dropper. The outer cover is fixedly connected to the inner cover. The button is inserted between the inner cover and the outer cover. The piston is sleeved on a piston connecting rod of the button and moves up and down with the button.

Embodiments of the invention related to dispensing devices (100), and more particularly to dispensing devices having a dropper or dispenser (200) associated with a container (900) full of product wherein the dropper (200) may be charged, separated from the container (900), and then used to dispense a product therefrom.

In various implementations, a dropper for a bottle may include a bulb with a flange and an extended leg. The dropper may be used as a cap, in some implementations, with or without a skirt. The dropper may inhibit leaks from a bottle when the dropper is used as a cap for the bottle.
