A method for the storage and delivery of a stable form of lactase to an infant as a dietary supplement. The lactase is stored first as a dry powder contained in a push cap. The push cap is then fixed to a bottle containing a plurality of anhydrous neutral oils. Once the push cap is fixed on the bottle, the push cap is pressed, releasing the lactase powder into the neutral oil. The bottle is then agitated to produce a mixture of lactase in the neutral oils. Finally, a dropper is used to deliver the stable lactase-oil mixture to the infant in need thereof.

A vented protective cap for a liquid dispenser, and a venting insert, in particular for such a protective cap. The protective cap has a cap wall which surrounds a cap interior. The cap wall has a venting aperture which is spanned by a flexible sheet-like structure. A boundary region of the sheet-like structure is fixed in an encircling manner to a boundary of the venting aperture. The sheet-like structure consists of at least two layers which bear directly against one another but, at least in a central region of the sheet-like structure, are not connected fixedly to one another.

A liquid dispensing device includes a multifunction membrane valve that, in addition to allowing the dispensing of drops with a drop-check mechanism, ensures and isolates the passage of the air to be filtered so that it does not contaminate the liquid in the interior of the dispensing device; it has a reduced number of parts; it facilitates proper assembly by counter pressure, without the need for threads or complex coupling elements; it avoids the need for rotational alignment when assembling the parts, among other advantages.

A dispenser for viscous products, including: a container for a product, a sealing cap designed to be screwed onto the container, a pipette, and a piston capable of causing a suction of the product into the pipette, the dispenser being arranged such that, when the cap is screwed onto the container, the unscrewing of the cap in the direction of opening of the dispenser causes, by itself, a movement of the piston producing the suction.

A two-piece dispensing closure for dispensing essential oils includes an insert received into a container opening and a closure body including a dispensing spout and a hinged cap. The cap is connected to the closure body by a living hinge to allow the user to selectively open and close the container. A tamper-evident tear strip is integrally formed with the closure body. The insert and the closure body including mating helical ramps which cooperate to insure that the insert remains installed within the container neck when the closure body is removed after purchase.

A device for dispensing a liquid medium (26) from a container (1), comprising a housing (13), a metering drum (2) accommodated therein and a sealing disk (14), the housing (13) having a drum outlet (3) and a system air admission structure (22), and the sealing disk (14) having an admission opening (12) and a drum inlet (4). The metering drum (2) comprises a metering chamber (5), a chamber outlet (6) and a chamber inlet (7). The metering drum (2) further has a rotary valve (8), said rotary valve (8), in a first working position, connecting the drum inlet (4) to the chamber inlet (7) while closing the chamber outlet (6), thereby admitting air to the container (1) and removing air from the metering chamber (5). In a second working position, The metering drum (2) closes the chamber inlet (7) while connecting the drum outlet (3) to the chamber outlet (6), thereby further admitting air to the metering chamber (5) and the air admission channel (11) being connected to the system air admission structure (22).
