An airtight bag is provided for preserving a first substance and at least one second substance. A first opening device is provided for providing a first opening and an access by a user to the first substance in the bag, and at least one second opening device is provided for, subsequent to accessing the first substance via said first opening, providing at least one second opening and an access by the user to the at least one second substance in the bag. The first opening device is positioned such that first opening facilitates the access by the user to the first substance. The at least one second opening device is positioned such that the at least one second opening facilitates the access by the user to the at least one second substance.

A bag for producing a foam-in-bag dunnage material comprises a closed edge portion and, in a non-sealed state of the bag, an open edge portion, the closed and open edge portions delimiting an inner bag volume. The invention proposes that a bag structure of the bag comprises a mixing chamber which is adapted to receive foam precursor substances, which is arranged within the inner bag volume, which is at least partially and initially delimited against the remainder of the inner bag volume, and which in the non-sealed state of the bag is connected to the open edge portion.

A method of preparing a pharmaceutical product in a single multiple chamber flexible bag. A pharmaceutical product is introduced in a liquid state into a first chamber of the flexible bag through a first port. The pharmaceutical product is lyophilized within the first chamber of the flexible bag to provide a lyophilized pharmaceutical product. The flexible bag has a second chamber and the first chamber and the second chamber are separated by a breakable seal. The second chamber further includes a reconstituting solution for reconstituting the lyophilized pharmaceutical product in the first chamber. A user may apply pressure to the flexible bag to break the seal and mix the lyophilized pharmaceutical product and the reconstituting solution to order to administer the pharmaceutical product to a patient.

An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

A waste treatment includes a package with compartments. A surfactant, an oxidizing agent, and, optionally, a liquid may be disposed within the compartments. The oxidizing agent is within a compartment that does not contain the surfactant or the liquid. A bursting force may unseal a sealed end of each compartment. The liquid flushes the surfactant and the oxidizing agent out of the package into a non-contact agitating toilet. A dual compartment package made with a fluidly disintegrable material may separate the surfactant from the oxidizing agent where the liquid may not be provided. The waste treatment may be mixed with a waste deposited within the non-contact agitating toilet. The package may disintegrate in the presence of the liquid to allow the reactive components to mix. A plurality of waste treatments may be connected. A perforated barrier may separate a first waste treatment from a second waste treatment.

The present invention provides a synthetic resin package (2) improved at least partially in the ease of use as compared with conventional packages, and containing at least one pouch (14) which accommodates a dental liquid (21) and which, when pressed, is unsealed at one end edge and allows the dental liquid to be flowed out through the unsealed one end edge.

In the package (2), both side edges (4a, 4b) and a bottom edge (6) are closed throughout; an applicator insertion section (10) and a pouch housing section (12) situated adjacently in a lateral direction are defined; in a top edge (8), a site (8b) corresponding to the pouch housing section (12) is closed at least partially, while a site (8a) corresponding to the applicator insertion section (10) is open; and the pouch (14) is positioned within the pouch housing section (12), with the one end edge to be unsealed facing downward.

Disclosed are disposable containers, such as a stand-up pouch, for heating food in a microwave oven and while automatically dispensing sauce onto the food. Methods and apparatuses for making sauce packets and disposable containers are also disclosed.

The present invention provides a method for preparing and delivering a multi-component comestible into a mouth of a consumer. The comestible are stored in separate compartments and combined upon expulsion from the respective compartments.
