Abstract

A fluid container (1, 1 '') is provided with identical valves (8, 9) at opposite first and second ends thereof and comprises a single liquid (2), such as a solvent, wherein activated carbon is provided in the liquid to adsorb impurities. The activated carbon may be contained in a nonwoven fibrous packet (12) disposed in the liquid as the tea leaves may be contained in a tea packet. The first and second end portions (4 a,4 b) each have a valve of identical function, for example of identical construction, which permits the fluid container (1, 1') to be mounted in the dispensing apparatus (14) irrespective of its orientation in the dispensing apparatus, since the liquid contained in the container can be dispensed through either valve.

  5. 5. A container according to claim 3, wherein an adsorbent material is provided in the liquid, the adsorbent material being contained within a packet containing a packet material permeable to the liquid.
  6. 6. The container of claim 5, wherein the wrapper comprises a nonwoven fibrous material that is permeable to liquid.
  7. 7. The container of claim 5, wherein the wrapper comprises a liquid permeable spun-bonded high density polyethylene fiber material.
  8. 8. The container of any one of claims 1,2, 3, 4, or 5, wherein the liquid is an organic solvent suitable for cleaning an end face of an optical fiber.
  9. 9. The container of any one of claims 3, 4 or 5, wherein the liquid comprises a solvent mixture comprising: about 30% to about 60% by weight of methyl nonafluorobutyl ether, About 30% to about 60% by weight of methyl nonafluoroisobutyl ether, About 5% to about 10% by weight of (Z) -1-chloro-2, 3 trifluoropropane, and The pressurized gas comprises heptane present in an amount of from about 5% to about 10% by weight of the solvent mixture and pressurized gas.
  10. 10. A container according to claim 1 or claim 2, wherein the first and second valves are female, concave stem valves.
  11. 11. A container according to claim 1 or 2, wherein the first and second valves are each male stem valves.

Description

Container for storing and dispensing liquids Cross Reference to Related Applications The present application claims the benefit of U.S. patent application No. 63/587,322, entitled "RECEPTACLE FOR STORING AND DISPENSING Liquids (containers for storing and dispensing Liquids)" filed on month 10 and 2 of 2023, the disclosure of which is incorporated herein by reference in its entirety. Technical Field The present invention relates to a container for storing a liquid to be dispensed from the container, for example, for storing and dispensing a solvent used in the cleaning of fiber optic connectors and fiber optic endfaces. Any other liquid that can be dispensed by gas pressure can be stored in and dispensed from the container. The container may comprise a valved canister that may be inserted into any suitable dispensing device, such as a cleaning device for fiber optic connectors and endfaces. For example, when the liquid is depleted or if a different liquid is desired, the container can be easily removed from the device in which it is placed and replaced with a new canister. The container is designed as a consumable for use with any suitable dispensing device. For example, a container may be used to supply solvent to the fiber cleaning device. Such devices emit pulses of compressed gas to entrain and atomize the solvent and entrain the atomized solvent in a gas stream that impinges on the fiber optic component to be cleaned. Typically, such cleaning devices are accompanied by pulses of air flow that do not contain solvent in order to dry the parts being cleaned. Background U.S. patent 6,196,421 to Williams ("Williams") at 3/6/2001 discloses a disposable, hand-held aerosol reservoir with a dispensing valve at each opposite end. See, for example, fig. 4 and 8. In various configurations, different types of valves are provided at each end to produce different types of emissions, such as water flow, spray, or foam. See fig. 2,3, 4 and 7. In other embodiments, two different products may be contained in the tank, as shown in fig. 5-8. Fig. 6 and 8 illustrate the structure of physically separating two different products by the barriers 69, 70 of fig. 6 and the collapsible bags 181A, 181B of fig. 8. British patent application GB 261025A to lashaton ("Rushton") 3, 29, 2023 discloses a multipurpose water bottle comprising a mesh structure with an adsorbent, which may be activated carbon, disposed in the water to purify the water. See, for example, fig. 3 and 5. The use of activated carbon as adsorbent is disclosed, for example, on page 10, line 22 and later, and in claim 13. Page 8, lines 25-31 disclose that the mesh structure may "resemble a variety of well known tea bags". The application teaches the use of a mesh structure (e.g., a tea bag or small refillable mesh reservoir) that can be replaced or refilled with adsorbent as needed. The disclosed advantages over fixed adsorbent columns through which water flows into a vessel are that such columns eventually saturate and may become a source of contamination, while the mesh structure may be replaced or refilled with new adsorbent as needed. The abstract of korean patent No. 2002-008977A shows a tea bag filled with activated carbon for use in purifying water. Disclosure of Invention According to the present invention, there is provided a container for liquids (such as solvents) which may include a container body having a first end and an opposite second end, each of the ends containing a valve, the first and second ends and their respective valves being identical. The orientation of the container is thus not important when installed in a given cleaning device, since the configuration is the same regardless of which end (first or second) is facing upwards or downwards. The adsorption media (such as activated carbon) may be disposed in a liquid contained in the vessel. The adsorption media may be dispersed throughout the liquid as pellets, or the pellets may be contained in a liquid permeable bag. In particular, according to the present invention, there is provided a container for storing and dispensing a single liquid, the container comprising the following components. A closed container body containing a single liquid, the container body having a first end with a first dispensing valve disposed thereon and an opposing second end with a second dispensing valve disposed thereon. The first valve and the second valve are functionally identical, whereby such liquid can be dispensed from the container via either the first valve or the second valve by opening one of the first and second valves that is in contact with such liquid. Other aspects of the invention include one or more of the following features, which may be achieved in any suitable combination, that the adsorbent material may be disposed in a liquid, that a pressurized gas may be disposed within a vessel to form bubbles defining a headspace above the liquid, that the adsorbent material may be dispersed as particles
