摘要:
An inflatable web, and method and apparatus for inflating the web, which generally includes two sheets having inner surfaces sealed to each other in a pattern defining a series of inflatable chambers of predetermined length, each of the chambers having at least one change in width over their length; an inflation port located at a proximal end of each chamber, the inflation ports being formed by intermittent seals between the sheets; and longitudinal flanges formed by a portion of each of the sheets that extend beyond the inflation ports and intermittent seals.

An apparatus for forming inflated containers generally includes a mechanism that conveys a web of film along a path of travel, the film web including one or more pre-formed flexible containers; an inflation assembly positioned adjacent the travel path to direct gas into the containers, thereby forming inflated containers; and a device for sealing closed each inflated container. Various improvements for more reliably and consistently inflating the containers are also disclosed.

An apparatus for forming inflated containers includes a film web that includes two juxtaposed film plies, a closed longitudinal edge, an open longitudinal edge, and a series of transverse seals having a first end located at the closed longitudinal edge and a second end terminating a predetermined distance from the open longitudinal edge such that each of the juxtaposed film plies have a section extending beyond the second end of the transverse seals, thereby forming a skirt that extends between adjacent containers at the open longitudinal edge. Such skirt facilitates inflation of each container.

A packaging device is disclosed for forming packaging cushions of the type that include a plastic bag filled with a solid foam, and wherein the cushions are initially formed of a plastic bag filled with a foamable material that reacts and then hardens to form solid foam. The device comprises means for advancing a sheet of plastic film material that has been center-folded to form a doubled web with one closed edge defined by the center fold and one open edge defined by the adjacent edges of the sheet. Means are included for injecting a foamable composition into the center-folded web between the two folded portions of the sheet, as are means for forming a substantially linear seal along the open edge and substantially parallel to the open edge to thereby longitudinally seal the open edge of the web. The invention further includes means for periodically interrupting the linear seal to provide an unsealed portion along the otherwise sealed edge, and means for transversely sealing the web after foamable composition has been injected, and for concurrently separating a formed and filled bag from the advanced film material.

A sealing and severing apparatus is disclosed for sealing plastic bags formed in succession from stock plastic film material and then severing the sealed bags from one another. The bags are filled with a foamable composition while they are being formed so that when the formed and filled bags are placed in a container, the foamable composition fills the bag with foam to thereby produce a customized foam cushion for any objects in the container.

A detachable mixing chamber is constructed and arranged to receive a plurality of fluid components from a source thereof for forming a fluid such as a foam to be discharged therefrom. The chamber includes a core having a bore therein and a plurality of inlet openings arranged in communication with the bore for supplying the fluid components from such source to the bore and means for maintaining the core under a restraining force in an axial and radial direction. The chamber is removably secured to a dispensing apparatus in a manner to be accessible from the outside thereof for detachment therefrom.

A quick-acting electric cigar lighter employing a bimetallic disk constituting an electric switching member. The disk is secured in place by a mounting stud, utilizing a welding procedure. The welding does not adversely affect the functioning of the switch due to the provision of a central offset portion in the disk, which tends to relieve stresses on the weld, preventing any failure at that location. The lighter is activated by pushing the igniting unit inward to bring the heating element cup into physical contact with the bimetallic disk. Over-stressing of the bimetallic disk is prevented by mounting the same in a recessed insulating block which has lands that are engaged by the cup after a pre-determined amount of actuation of the plug has occurred. An effective, long-life contact between the cup and the disk is had by the use of special metals which co-act to minimize pitting, deterioration, etc., one metal comprising aluminum which cooperates with other metals such as copper or silver. .Iadd.

A wound cleansing solution dispenser that indicates the volume of liquid remaining and reduces medical waste. A shield is mounted onto the dispenser to prevent any contaminated fluids from splashing onto the care giver. The dispenser can be brought in a sterile condition to the patient free from any separate power supplies or fluid source lines. The stream pressure of the dispenser may be adjustable but it may be set for a substantially constant pressure over the volume of fluid. The dispenser may be used in any orientation and still deliver wound cleansing solution at the selected pressure.
摘要:
An inhalation device in the nature of a metered dose inhaler is designed specifically for existing respiratory drugs to be employed in hospitals and/or by patients at home. The device is constructed of a housing which defines an aerosol chamber for a metered dose of a medicant containing aerosol from a cartridge. The cartridge is supported wholly within the aerosol chamber. An actuating valve mechanism is slidingly receiving within an open end of the housing and includes a projecting portion to which a compressive force may be applied. Upon application of the compressive force, for example, by forcing the open end of the housing against a supporting surface, the outlet valve mechanism of the cartridge is activated to dispense a metered dose of medicant into the aerosol chamber in the form of an aerosol.
