CHEMICAL PRECURSOR BUBBLER ASSEMBLY WITH ROUTING STRUCTURE

Abstract

A bubbler apparatus may include a container, a lid, a sealing member and at least one routing member. As the lid is tightened to the container and the sealing member is compressed, the routing member(s) does not contact the inside bottom surface of the container. Instead, there is a small gap between the routing member and the bottom surface of the container. The routing member may compress the substance in the container that the gas is saturated with or may slice through the substance.

Description

IV. DETAILED DESCRIPTION

[0023] Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, and wherein like reference numerals are understood to refer to like components, FIG. 3-5 shows a bubbler apparatus 50 according to some embodiments of this invention. The bubbler apparatus 50 may include a container 52, having a bottom 55 defining an inside bottom surface 54, and a removable lid 56. Fasteners, not shown, may be received in holes 58, 60 in the lid 56 and container 52 to secure the lid 56 to the container 52. A sealing member 62, such as a gasket, may be positioned between the lid 56 and the container 52 to form a seal between the lid 56 and the container 52 during operation of the bubbler apparatus 50. The apparatus may include an inlet 64 through which a gas stream enters the bubbler and an outlet 66 through which the gas stream exits the bubbler. Valves and piping 68 may also be provided to operate the bubbler apparatus 50 as is well known to those of skill in the art.

[0024] With reference now to FIGS. 3-6, the bubbler apparatus 50 may include a routing structure 70 that routes the gas as it moves through the bubbler as described above and well known to those of skill in the art. The routing structure 70 may include one or more routing members 72 that extend, once inserted within the container 52, laterally and vertically. While the routing members 72 shown are planar in shape, it should be understood that any shape chosen with the sound judgment of a person of skill in the art may be used with this invention. It should also be understood that the number of routing members 72 used may be any chosen with the sound judgment of a person of skill in the art. Five are provided in the embodiment shown.

[0025] With reference now to FIGS. 4-6, the routing members 72 may be similarly shaped or may have differing shapes. The routing members 72 may be positioned within the container 52 in any manner chosen with the sound judgment of a person of skill in the art to achieve the desired flow characteristics for the gas as it passes through the bubbler. For the embodiment shown, see especially FIG. 6, three of the routing members 72 have sides near one side of the container 52 and the other two routing members 72 have sides near the opposite side of the container 52. As shown in FIG. 5, the container 52 may have a height H1 from the inside bottom surface 54 to the top of the container. At least one routing member 72 may have a height H2 from the bottom surface of the lid 56 to its distal end (away from the lid 56). For the embodiment shown, the routing members 72 are attached to the lid 56.

[0026] With reference now to FIGS. 4-8, the routing member 72 height H2 is smaller than the distance between the bottom surface of the lid 56 and the inside bottom surface 54 of the bottom 55 after the lid 56 is properly secured to the container 52 with the sealing member 62 properly sealed. This difference forms a gap 74 between the distal end of the routing member 72 and the inside bottom surface 54. Gap 74 may be any non-zero distance chosen with the sound judgment of a person of skill in the art. In one embodiment, the gap 74 is between 0.10 inches and 0.01 inches. In one specific embodiment, gap 74 is about 0.03 inches.

[0027] In use, when the lid 56 is properly attached to the container 52 (compressing the sealing member 62) and routing member(s) 72 is extended into the container, the distal end of the routing member(s) 72 does not contact the inside bottom surface 54 because of the gap 74. The distal end of the routing member(s) 74 may, however, contact the substance, such as a compound, within the container. For the embodiment shown in FIG. 7, the distal end of the routing member 72 is flat and thus compresses the substance within the container when inserted. For the embodiment shown in FIG. 8, the distal end of the routing member 72 is pointed and thus slices through the substance within the container when inserted. In both cases, the routing member(s) 72 provides the necessary seal with the inside bottom surface 54 of the bottom 55 without contacting the bottom surface 54.

[0028] A plurality of different embodiments of the invention is shown in the Figures of the application. Similar features are shown in the various embodiments of the invention. Similar features are structured similarly, operate similarly, and/or have the same function unless otherwise indicated by the drawings or this specification. Furthermore, particular features of one embodiment can replace corresponding features in another embodiment or can supplement other embodiments unless otherwise indicated by the drawings or this specification.
