Abstract

This disclosure relates generally to a containment system for containing a fluid. More specifically, the disclosure relates to a fitment for attaching a liner within a container and providing a fluid path from the liner to an outside of the containment system. The liner and at least a part of the fitment provide the wetted surfaces for the containment system, while the fitment has a portion that can be joined to an outer container that, for example, provides rigidity and light protection. The fitment may be a two-piece fitment with a liner fitment to which the liner may be joined, and a retainer that may be joined to a container, where the liner fitment and the retainer are joined to one another, for example by a mechanical connection. The liner and liner fitment may be fluoropolymers or other non-reactive polymers. The container and retainer may be UV-blocking polymers.

Description

Multiple accessories for fluid containers

The present invention generally relates to a containment system for containing a fluid. More specifically, the present invention relates to an accessory for attaching a liner to a container and providing a fluid path from the liner to an exterior of the containment system.

Some processes utilize fluid chemicals. The fluid chemistry may include, for example, acids, solvents, bases, photoresists, dopants, inorganic solutions, organic solutions, drugs, or the like. When using these chemicals, glass bottles can be used to properly contain the chemicals during storage, transportation, and ultimately during the process itself. Glass bottles are commonly used in containers because they provide ultraviolet (UV) protection and chemical resistance to wet surfaces when storing and transporting fluid chemicals.

The present invention generally relates to a containment system for containing a fluid. More specifically, the present invention relates to an accessory for attaching a liner to a container and providing a fluid path from the liner to an exterior of the containment system.

Some processes utilize fluid chemicals. The fluid chemistry can include, for example, acids, solvents, bases, photoresists, dopants, inorganic solutions, organic solutions, drugs, or the like. When using these chemical substances, a fluid containment system can be used to properly contain the chemical substances during storage, transportation, and finally during the process itself.

A fluid includes (but is not limited to) a substance that flows or deforms when a shear stress is applied. A fluid can include, for example, a liquid.

FIG. 1A shows a cross-sectional view of one end of a fluid containment system 100 according to an embodiment. The fluid containment system 100 includes a container 102, a holder 104 and a liner fitting 106.

The fluid containment system 100 is a system for containing chemical substances (such as, for example, acids, solvents, alkalis, photoresists, dopants, inorganic solutions, organic solutions, drugs, or the like).

The container 102 is a hollow container capable of containing a fluid in a liner (not shown in the figure) (such as the liner described below and shown in FIG. 6). The container 102 may be made of one or more polymers. The container 102 may be made of, for example, a stretch blow moldable polymer. Examples of materials that can be used in the container 102 include polyethylene (PE), polyethylene terephthalate (PET), polyethylene terephthalate (PETG), polyethylene terephthalate Methyl ester (PCTA), polycyclohexamethylene terephthalate (PCTG), polycarbonate (PC), polypropylene (PP), polyamide (PA), polyether sulfide (PES), polyphenylene PSU (PPSU), polymethyl methacrylate (PMMA), impact-resistant polystyrene (HIPS), polyethylene naphthalate (PEN), polyether ether ketone (PEEK), cycloolefin Hydrocarbon polymers, cyclic olefin copolymers or the like and copolymers containing these materials.
