  • the present disclosure provides for a safe means for packaging such individually separated compositions.
  • solutions having elevated peracid concentrations are viewed as being hazardous, and therefore, difficult to ship and sell to the public.
  • the multi-chamber containers of the present disclosure would allow for the peracid liquid to be packaged within the first chamber and enclosed within the container for safety. Such a configuration makes the system more safely shipped and stored because any leak from the first chamber would be retained within the container and, if the membrane separating the chambers is broken, safely dispersed and neutralized into the second liquid present in the second chamber.

  • the plunger is configured to move through the opening to facilitate puncture of the membrane.
  • This configuration when compared to the initial plunger configuration illustrated in FIGS. 1 A and 1 B, facilitates a shorter range of travel for the plunger needed to puncture and penetrate the membrane, because the sharp tip 241 of the plunger can be located in the chamber near the membrane prior to movement of the plunger toward the membrane.

  • any number of chambers and liquid compositions can be included in a multi-chamber container in accordance with the present disclosure.
  • the plunger configurations and associated chambers can be combined in any arrangement or embodiment disclosed herein.
  • a method for facilitating storing and mixing liquids can comprise obtaining a multi-chamber container having a first chamber configured to contain a first liquid composition, a second chamber configured to contain a second liquid composition, and a membrane operable to separate the first liquid composition and the second liquid composition. Additionally, the method can comprise facilitating puncturing of the membrane with a plunger to facilitate contact of the first liquid composition and the second liquid composition. In one aspect, the method can further comprise facilitating absorption of a mixture of the first liquid composition and the second liquid composition by a towelette. In another aspect, the multi-chamber container can comprise a cap for the second chamber and the cap includes the first chamber. It is noted that no specific order is required in this method, though generally in one embodiment, these method steps can be carried out sequentially.

Abstract

La présente invention porte sur un récipient à chambres multiples et sur des procédés associés pour stocker et mélanger des liquides et sur des procédés d'utilisation associés. Le récipient à chambres multiples comprend une première chambre configurée de façon à contenir une première composition liquide. Le récipient à chambres multiples comprend également une seconde chambre configurée de façon à contenir une seconde composition liquide. Le récipient à chambres multiples comprend de plus une membrane séparant la première composition liquide et la seconde composition liquide. La membrane peut être percée pour faciliter un contact de la première composition liquide et de la seconde composition liquide. De plus, le récipient à chambres multiples comprend un plongeur pouvant fonctionner de façon à percer la membrane. Le plongeur peut être configuré de façon à se déplacer à travers une ouverture de la première chambre opposée à la membrane de façon à faciliter un perçage de la membrane.
