The present disclosure provides a flexible pouch. In an embodiment, the flexible pouch includes opposing flexible films. The opposing flexible films define a common peripheral edge. The flexible pouch includes a microcapillary strip sealed between the opposing flexible films. A first side of the microcapillary strip is located at a first side of the common peripheral edge. A second side of the microcapillary strip is located at a second side of the common peripheral edge. A peripheral seal extends along at least a portion of the common peripheral edge. The peripheral seal includes a sealed microcapillary segment.

A discharge device for a liquid medium includes a storage container for receiving a medium, a discharge head which can be secured on the storage container and comprises a discharge opening for discharging the medium out of the storage container, an outlet valve which is paired with the discharge opening and comprises a pretensioned valve element that delimits a valve pre-chamber by means of a pressure application surface formed on a membrane. The pressure application surface has a stationary clamping region on the outside, and a pressure equalization channel which opens into the storage container and comprises a filter assembly that operates microbiologically and is inserted into the pressure equalization channel. The pressure equalization channel is separated from a medium path from the storage container to the discharge opening via the valve pre-chamber, and the pressure application surface has a cap-like edge protrusion as a clamping region which can be placed on a plate edge of the inner component of the discharge head on the inside. The plate edge has a stop that extends outward radially and forms a support surface for the edge protrusion while being spaced from the pressure application surface by a head surface of the plate edge.

A dispensing closure for a squeeze-type container produces a fan-type spray in a low pressure environment. The dispensing closure includes a closure body having an upper deck and a skirt depending from the upper deck. The skirt is configured and arranged to attach to a product container, such as a squeeze-type container. A flow conduit extends from an interior of the closure body and through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit has an entrance orifice and an exit orifice. The flow conduit and the closure body are integrally formed. The flow conduit includes a tip portion with an exit orifice defining a shape to provide a fan-type spray in a low pressure environment.

A fluid dispenser comprising a deformable outer shell (1) and a flexible inner pouch (2) that is arranged inside the shell (1) in such a manner as to define between them a compression space (E) that is filled with air, the pouch (2) containing a fluid for dispensing through a dispenser valve (4), the compression space (E) communicating with the outside through an air inlet valve (5), such that deformation of the shell (1) puts the air contained in the compression space (E) under pressure, the air under pressure acting on the pouch (2), so that the fluid therein is then forced through the dispenser valve (4), the dispenser also comprising a head (3) that is fitted on the shell (1) and on the pouch (2), the head (3) comprising a first valve support (34) on which the dispenser valve (4) is mounted, and a second valve support (35) on which the air inlet valve (5) is mounted; the dispenser being characterized in that it further comprises a hood (6) that is fastened in non-leaktight manner on the deformable outer shell (1), the hood (6) holding the head (3) in place on the deformable outer shell (1) and on the flexible inner pouch (21), the hood (6) including a window (63) in which the dispenser valve (4) is positioned.

Liquid dispenser for discharging pharmaceutical liquids, having a housing, an outlet opening and an outlet valve assigned to the outlet opening. The outlet valve includes a pressure chamber arranged upstream of a valve opening and delimited to one side by a valve plate of a valve body. By increasing the pressure in the pressure chamber, the valve can be opened. The pressure chamber has a flat form and has a large surface area in contact with liquid in relation to the volume. At least one portion of the valve plate which is in contact with liquid in the pressure chamber is of a valve plate material produced using metallocenes as catalysts.

A spray cap for a spray container constitutes a one-piece moulding of polymeric material and includes a cap plate in which a plurality of spray slits is formed. Integral with the cap plate is a non-return valve arranged to permit air to flow through it in one direction which, in use, is towards the interior of the spray container but substantially to prevent flow of air through it in the opposite direction.

An anti-backflow extrusion liquid container includes an elastic container for storing and extruding liquid, a spraying tube inserted into the elastic container, a first one-way valve for controlling the opening and closing of the spraying tube, and a second one-way valve for adjusting the air pressure in the elastic container. The first one-way valve is disposed in the middle of the spraying tube, and the second one-way valve is disposed at the bottom of the elastic container. The disclosure not only prevents the liquid in the guide tube from flowing back into the bottle body during the restoring process of the bottle body and thus avoiding the liquid in the bottle body from being contaminated, but also enables the bottle body to be restored quickly after pressing and thus prolonging the service life of bottle and improving work efficiency.

The fluid applicators disclosed herein include an applicator cap and a squeezable bottle that can be releasably and fluidically coupled together. The applicator cap includes a tube, conduit, passageway, reservoir, chamber, cavity, lumen, and/or other features that direct fluid exiting the squeezable bottle through the applicator cap to exit the applicator cap via an opening, aperture, or hole that is disposed at a transverse angle, which can be perpendicular, relative to a longitudinal axis of the squeezable bottle. The fluid exiting via the opening, aperture, or hole is expelled onto and/or into an applicator surface or pad to be applied to the body of the user. The squeezable bottle can be used as a handle to effectively extend the reach of the user to enable the user to rub the applicator surface or pad, with expelled fluid, on the remote areas of a user's body.

A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.

A dispensing head for a system for dispensing a product is described herein. The head includes a body having a housing that is provided with an anvil around which a nozzle is mounted. The nozzle includes an outlet orifice to place the housing in communication with the exterior, and wherein the head includes a membrane added around the periphery of the anvil in the housing in such a way as to form between the membrane and the nozzle a path for dispensing the product.
