A container for dispensing predetermined quantities of liquid comprises a first or primary container having a bottom portion, sidewall portion and open-ended neck portion. A second container comprising an elongated tubular substantially within the first container depending from the neck portion thereof. A third container disposed completely within the first container is integral with and disposed substantially concentrically around the second container. The third container comprises sidewall, bottom and top portions which together form a fluid sealing enclosure, the top and bottom portions being integral with and supported by the outer surface of the second container. The third container, communicates with the primary container by means of an opening provided in the upper portion to its sidewall portion serving as a liquid inlet. A second tubular member of relatively small diameter connects the bottom portion of the second container with the portion of the third container. In normal use, tipping of the container to pouring position results in the discharge of liquid present in the second container. Simultaneously therewith, liquid from the primary container enters the third container through the liquid inlet opening. Restoration of the container to its normal upright position causes liquid in the third container to enter the second container through the tubular member connecting the bottom portions of these containers.
The tubular dosing mechanism can be inserted into the dispensing opening of a liquid container. It has a dosing channel the outer end of which is closed, and a discharge channel which is axially separated from the dosing channel and is open at the outer end. Both the channels are connected to a collecting area located further inwards than the inner end of the dosing channel. The dosing channel has axially spaced inlet and outlet orifices connected to the inner area of the liquid container. Of these, the outlet orifice is positioned further axially inwards is the issuing-opening into the dosing channel of a channel which extends through the base wall of the collecting area. Modifications are shown especially for use where the liquid is more viscous than water or the liquid container has an easily deformable sidewall.
A dose-measuring device designed to be inserted in the neck of a flask (1) includes a first metering compartment (A) and a second reserve compartment (B) communicating with the outlet of the measuring device and the metering compartment (A). The device also includes an outer tubular element (5) nested in the neck (2a) of the flask (1), closed at its lower end and open at its upper end and an inner tubular element (5) nested sealed in the outer tubular element (5), including an intermediate body (16), delimiting inwards, the metering compartment and a lower part forming a transfer conduit (23) extending downwards emerging into the metering compartment (A) and in the reserve compartment (B).
A device for the apportioned delivery of liquid (3) from a storage container (2) through an outlet tube (20) which enters into the low position, the delivery taking place only upon the second turning over the device. A cup-shaped housing (5) is divided by a partition wall (16) into an upper chamber (I) and a lower discharge chamber (II), the discharge chamber (II) and upper chamber (I) of the housing being connected to each other by a passage hole (17), and a feed opening (33) is formed in the upper chamber (I). An outlet tube (20) debouches above the partition wall (16), and an air passage is formed in the region of the upper chamber (I). In order to obtain a more advantageous development from a manufacturing standpoint while retaining or possibly even increasing the accuracy of dosaging, the outlet tube (20) is attached to the upper chamber (I) and the discharge chamber (II) is attached by detent to the upper chamber (I).
A metering device for successively dispensing uniform volumes of liquid from a container. The upper portion of the dispensing device is divided into a dispensing passage and a metering chamber by a vertical wall. The lower portion of the dispensing device is undivided forming a collecting chamber, the upper portion of which communicates with both the metering chamber and the dispensing passage. The metering chamber has axially spaced inlet and vent openings connected to the inner area of the liquid container. The metering chamber is partially segregated from the collecting chamber by a baffle protruding from the vertical wall. This baffle insures accurate operation of the dispensing device and reduces its necessary volume and length.
The present invention is a self-measuring container that dispenses only a specific amount of fluid each time fluid is poured from the container. This container has a storage chamber where the fluid initially resides and a measuring/dispensing chamber, below the storage chamber, where the specific amount of the fluid that will be dispensed during the next pouring operation resides. An aperture at one end of the container connects the storage and dispensing chambers. This aperture permits the fluid in the storage chamber to flow into the dispensing chamber. The container dispenses the fluid through an exit channel that extends from the dispensing chamber to the top of the container. The storage chamber bottom serves to separate the storage and dispensing chambers and acts as a barrier during a pouring operation to prevent fluid from flowing from the storage chamber to the dispensing chamber until desired. In another embodiment, the storage and dispensing chamber do not have a common wall, but the dispensing chamber is formed to minimize the draw necessary during the formation process. The measuring chamber may also contain a diaphragm to permit the volume within the chamber to be adjusted.
