Title: Expandable closure system

Description:
RELATED APPLICATION(S) 
     This application claims priority to provisional application U.S. 63/274,259, filed on Nov. 1, 2021, entitled “EXPANDABLE CLOSURE SYSTEM” which is incorporated by reference herein. 
    
    
     FIELD 
     The present disclosure relates to closures that enclose and protect line splice holders and the spliced lines thereon. 
     BACKGROUND 
     Elongate lines, such communication wires, cables, optical fibers or the like, extend to a use location (e.g., a building, dwelling of the like). At the use location, the elongate lines are connected for termination, splicing or the like. 
     Typically, at the use location, such termination, splicing or the like, is performed upon at least one splice holder or similar structure. Also, typically at the use location, a closure is provided for the at least one splice holder to be located therein. The closure encloses and protects the at least one line splice holder and the terminations, splicing or the like thereon. 
     As can be appreciated, the closure has an interior volume. The at least one line splice holder and the terminations, splicing or the like thereon must fit within the closure. If there is a later desire to have a greater number of splice holders and associated terminations, splicing or the like thereon (e.g., such may occur during a system upgrade), a lack of further available interior space within the closure may occur. 
     To address the topic of needed further interior space, a new, larger closure is provided as a complete replacement. It is to be noted that providing a new, larger closure may be costly and may be a time-consuming process. It is to be noted that providing a new, larger closure may also involve risks of damage, disconnection and the like to lines and/or contents (e.g., splice holder(s)) within the original closure. Such damage, disconnection and the like may also be associated with disruption of provided service (e.g., communications). 
     SUMMARY 
     This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. 
     In accordance with one or more aspects, the present disclosure provides a closure enclosing and protecting at least one line splice holder. The closure includes a first housing portion enclosing at least a portion of a hollow interior of the closure, the at least one line splice holder being located within the hollow interior. The first housing portion has a portal through which plural lines extend into the hollow interior. The closure includes a second housing portion actuatable with respect to the first housing portion to provide an additional portion of the hollow interior. The additional portion of the hollow interior is a volume to receive additional of the at least one line splice holder. The closure includes a coupling for connecting the second housing portion to the first housing portion. 
     In accordance with one or more aspects, the present disclosure provides a closure enclosing and protecting one or more line splice holders. The closure includes a first housing portion defining a first portion of an interior of the closure. The closure includes a second housing portion defining a second portion of the interior of the closure. The closure includes a coupling for connecting the second housing portion to the first housing portion. The first housing portion and the second housing portion are movable relative to one another between a first position and a second position. When the first housing portion and the second housing portion are in the first position relative to one another, the interior of the closure has a first volume. When the first housing portion and the second housing portion are in the second position relative to one another, the interior of the closure has a second volume greater than the first volume. The first volume accommodates a first number of the one or more line splice holders. The second volume accommodates a second number, greater than the first number, of the one or more line splice holders. 
     The following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages, and/or novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.

     DETAILED DESCRIPTION 
     The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of the claimed subject matter. It is evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are illustrated in block diagram form in order to facilitate describing the claimed subject matter. Relative size, orientation, etc. of parts, components, etc. may differ from that which is illustrated while not falling outside of the scope of the claimed subject matter. 
     An example closure  10  in accordance with at least one aspect of the present disclosure is shown within  FIGS.  1 - 3   . The closure  10  is for enclosing and protecting at least one line splice holder.  FIG.  4    shows an example of line(s)  20  that may enter a closure, such as the closure  10  ( FIGS.  1 - 3   ), an example line splice holder  22 , that may be within a closure, such as the closure  10 , and example other structure(s)  24  that may be within/associated with a closure, such as the closure  10 . It is to be appreciated that  FIG.  4    is not provided to indicate any limitation upon the present disclosure.  FIG.  4   , is only to provide an example of a use environment for a closure, such as the closure  10 . It is to be noted that the examples shown within  FIG.  4    may also be associated with other closures presented within this disclosure. Such provides an example of a use environment for such other closure(s). It is to be noted that the use environment (e.g., line(s), line splice holder(s), and other structure(s)) may be varied, different, be of different number, etc. 
     Returning focus to  FIGS.  1 - 3   , the example closure  10  includes a first housing portion  30  enclosing at least a portion of a hollow interior  32  of the closure  10 . Within the shown example, the first housing portion  30  has a cylindrical shape. Within an example, at least one line splice holder, possibly the example line splice holder  22  ( FIG.  4   ), is to be located within the hollow interior  32 . The first housing portion  30  has a portal  34 . Within the shown example, the portal  34  is an open end (e.g., an opening) at an axial end of the cylindrical shape. Within an example, plural lines, such as the lines  20  shown within  FIG.  4   , extend into the hollow interior  32  through the portal  34 . It is to be appreciated that the portal  34  may receive structure (e.g., a cap, a plug or similar, such as shown as part of the other structure(s)  24  shown within  FIG.  4   ). 
     The example closure  10  includes a second housing portion  40 . It is to be appreciated that the second housing portion  40  is actuatable with respect to the first housing portion  30  to provide an additional portion  32 A of the hollow interior  32 . Within an example, the additional portion  32 A of the hollow interior  32  is a volume to receive one or more additional line splice holder(s). It is to be appreciated that use of the second housing portion  40  is optional (e.g., compare  FIG.  2    and  FIG.  3   ). 
     It is to be appreciated that the aspect of the second housing portion  40  being actuatable with respect to the first housing portion  30  to provide an additional portion  32 A of the hollow interior  32  is to be broadly interpreted. In general, the second housing portion  40  is involved in some activity (e.g., motion, attachment, or the like) relative to the first housing portion  30  such that the result is the provision of the additional portion  32 A of the hollow interior  32 . The present example closure  10  ( FIGS.  1 - 3   ) is provided as just an example of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. Other example closures discussed later provide other examples of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. However, it is to be appreciated that such discussed examples need not be limitations upon the present disclosure and that other examples are contemplated and within the scope of the present disclosure. 
     The example closure  10  includes a coupling for connecting the second housing portion  40  to the first housing portion  30 . It is to be appreciated that the coupling for connecting the second housing portion  40  to the first housing portion  30  is to be broadly interpreted. The coupling may have a variety of constructions and configurations. Such variety is within the scope of the present disclosure. Within the shown example of  FIGS.  1 - 3   , the example coupling for connecting the second housing portion  40  to the first housing portion  30  are matting threaded portions  44 ,  46  respectively on the first housing portion  30  and the second housing portion  40 . Within the shown example, the threaded portion  44  is a female threaded portion and the threaded portion  46  is a male threaded portion, but such may be reversed. The second housing portion  40  is connected to the first housing portion  30  via inserting the threaded portion  46  into the threaded portion  44  and the second housing portion  40  is rotated relative to the first housing portion  30  until sufficient tightening occurs. See  FIG.  3   , which shows the second housing portion  40  sufficiently tightening onto the first housing portion  30 . Again, it is to be appreciated that the use of threaded portions provides just an example and that other examples, which include other constructions and configurations (e.g., other/additional portions) for connection and holding of the housing portions, are within the scope of the present disclosure. For example, collars, clamps, twist-locks, interfitting portions, etc. may be included within other examples that are within the scope of the present disclosure. 
     It is to be appreciated that the above discussed broad example is to provide a broad appreciation of the scope of the disclosure. It is to be appreciated that additional/different components/structures/features may be provided. As an example of such, the example of  FIGS.  1 - 3    is now further described to regarding additional components/structures/features.  FIG.  1    shows a cap  50  and two O-ring seals  52 ,  54  as additional components. 
     The first housing portion  30  has an annular shoulder  60  encircling an entrance to the threaded portion  44 . The second housing portion  40  has an annular shoulder  62  encircling a distal end of the threaded portion  46 . The O-ring seal  52  is for seating against the annular shoulder  60  of the first housing portion  30 . When the second housing portion  40  is connected to the first housing portion  30 , via inserting/tightening the threaded portion  46  into the threaded portion  44 , the O-ring seal  52  is also seated against the annular shoulder  62  of the second housing portion  40 . As such the O-ring seal  52  seals between the first and second housing portions  30 ,  40 . See  FIG.  3   . Of course, other examples, such as examples that do not include threaded portions may utilize other constructions and configurations. 
     At a second end, distal from the threaded portion  46  and shoulder  62 , the second housing portion  40  has a female threaded portion  74  and an annular shoulder  76  encircling an entrance to the threaded portion  74 . The O-ring seal  54  is for seating against the annular shoulder  76  of the second housing portion  40 . It is to be appreciated that the female threaded portion  74  of the second housing portion  40  has the same size and configuration as the female threaded portion  44  of the first housing portion  30 . Here also, such is just an example and that other examples, that may utilize other constructions and configurations (e.g., that do not include threaded portions for connection), are within the scope of the present disclosure. 
     The cap  50  has a male threaded portion  80  and an annular shoulder  82  encircling a distal end of the threaded portion  80 . It is to be appreciated that the male threaded portion  80  of the cap  50  has the same size and configuration as the male threaded portion  46  of the second housing portion  40 . The male threaded portion  80  of the cap  50  may threadingly engage/mate into the female threaded portion  74  of the second housing portion  40 . As such, the cap  50  connects to the second housing portion  40 , via inserting/tightening the male threaded portion  80  into the female threaded portion  74 . During such insertion/tightening, the second O-ring seal  54  is also seated against the annular shoulder  82  of the cap  50 . As such the second O-ring seal  54  seals between the second housing portion  40  and the cap  50 . See  FIG.  3   . Such connection of the first housing portion  30 , the second housing portion  40  and the cap  50  provides an enclosed space that has the hollow interior  32  with the additional portion  32 A. See  FIGS.  1  and  3   . 
     It is to be appreciated that the example closure  10  as shown in  FIG.  3    may be a result of a desire to have the additional portion  32 A of the hollow interior  32 . Such may be part of additions of splice holder(s)  22 , additions of example other structure(s)  24 , or the like. 
     It is to be appreciated that the example closure  10 , with inclusion of the second housing portion  40  and both O-ring seals  52 ,  54 , may be provided as a kit. The use of the second housing portion  40  and both O-ring seals  52 ,  54  may be an option. Also, the provision of the second housing portion  40 , with use of both seals  52 ,  54 , may be an optional add-on. It is to be appreciated that for other examples, the kit may, of course, contain other, different items. Such different items may be dependent upon the variation, such as variations in the connections. Thus, other example kits may include other connection items such as collars, clamps, couplers, clips, closures, interfitting parts, etc. to hold the housing portions. So, the specifics as to the connections (e.g., use of threaded portions of the shown example) need not be a limitation upon the present disclosure. 
     Focusing now to  FIG.  2   , recall that the male threaded portion  80  of the cap  50  has the same size and configuration as the male threaded portion  46  of the second housing portion  40 . As such, the male threaded portion  80  of the cap  50  may threadingly engage into the threaded portion  44  of the first housing portion  30 . The first O-ring seal  52  is also seated against/between the annular shoulder  60  of the first housing portion  30  and the annular shoulder  82  of the cap  50 . The second housing portion  40  and the second O-ring seal  54  are not utilized within the arrangement as shown within  FIG.  2   . 
     It is to be appreciated that the example closure  10  as shown in the arrangement of  FIG.  2    may be a result of a desire not to have the additional portion  32 A of the hollow interior  32  (i.e., only the hollow interior  32  as provided by the first housing portion  30 ). Such may be associated within use of just one or other lower number of splice holder(s)  22 , other structure(s)  24 , or the like. As such, closure  10  is an example of a closure wherein the second housing portion  40  is removed from the first housing portion  30  to provide a relatively smaller hollow interior  32  of the closure and the second housing portion is added to the first housing portion for a relatively larger hollow interior (i.e.,  32  and  32 A) of the closure. Again, the connection of the shown example includes a threaded connection, but such is only an example that that other variations are within the scope of the present disclosure. As such, the connection that is intended to only provide the relatively smaller hollow interior may be varied based upon the variation of the connection that is for adding the additional portion of the interior via the second housing portion. 
     It is to be appreciated that, if desired, still further housing portions (e.g., third, etc.) could be utilized for providing still further additional portions to the hollow interior. Such may be accomplished via providing such third, etc. housing portions to be duplicates of the second housing portion  40 . Also, as needed, additional (e.g., third, etc.) O-rings, that are duplicates of the second O-ring, may be provided as needed. Each successive housing portion (e.g., third) would be threadingly engaged, with an O-ring interposed for sealing, to the previous housing portion (e.g., second) in a sequence. The cap  50  would be threadingly engaged, with an O-ring interposed, to the last housing portion of the sequence. Here also, variation (i.e., variation from use of threaded connections), are contemplated and within the scope of the present disclosure. 
     It is to be appreciated that all of such additions of housing portions (e.g., the second housing portion  40  added to the first housing portion  30 , a possible third housing portion added to the second housing portion  40 , etc.) may be accomplished to provide successive additional portion(s) (e.g.,  32 A) to the hollow interior  32 . It is to be appreciated that such additions may be accomplished with no or only minimal disturbance to the line(s)  20 , line splice holder  22 , other structure(s)  24  that may already be within/associated with the pre-existing, and smaller hollow interior  32  of the closure  10 . 
       FIGS.  5 - 7    show an example closure  110  in accordance with at least one aspect of the present disclosure. The example closure  110  includes an ability to telescope to change volume size of a hollow interior  132  of the closure  110 . 
     The example closure  110  includes a first housing portion  130 A/ 130 B ( 130 ) enclosing at least a portion of the hollow interior  132  of the closure  110 . Within the shown example, the first housing portion  130 A/ 130 B ( 130 ) has a general cylindrical shape. Within an example, at least one line splice holder, possibly the example line splice holder  22  ( FIG.  4   ), is to be located within the hollow interior  132 . The first housing portion  130 A/ 130 B ( 130 ) has a portal  134 . Within the shown example, the portal  134  is an open end (e.g., an opening) at an axial end of the cylindrical shape. Within an example, plural lines, such as the lines  20  shown within  FIG.  4   , extend into the hollow interior  132  through the portal  134 . It is to be appreciated that the portal  134  may receive structure (e.g., a cap, a plug or similar, such as shown as part of the other structure(s)  24  shown within  FIG.  4   . 
     It is to be noted that example first housing portion  130 A/ 130 B ( 130 ) is shown within  FIG.  5    as two pieces (i.e., piece  130 A and piece  130 B). The two pieces  130 A and  130 B are made as separate items and that connected together for use. It is to be appreciated that first housing portion  130  may be made as a single piece. Of course, such modification is within the scope of the present disclosure. The making of two pieces  130 A and  130 B as separate items may allow at least some of the two pieces  130 A and  130 B to utilized within other examples (e.g., piece  130 A may be utilized as the first housing portion  30  of the example shown in  FIGS.  1 - 3   ). 
     In view of the first housing portion  130 A/ 130 B ( 130 ) being shown within  FIG.  5    as two pieces (i.e., piece  130 A and piece  130 B), some structures upon the two pieces that are associated within the use of two pieces are explained. The first and second pieces  130 A,  130 B include a coupling for connecting the first and second pieces together. Within the shown example of  FIG.  5   , the coupling for connecting the first and second pieces  130 A/ 130 B are matting threaded portions  144  (hidden from view in  FIG.  5   , represented via dash hidden indicating lead line),  46  respectively on the first piece  130 A and the second piece  130 B. Once the threaded portions  144 ,  146  are tightened together, the first and second pieces  130 A/ 130 B the first and second pieces of the first housing portion  130 A/ 130 B ( 130 ) no longer move relative to each other. But again, the first housing portion  130 A/ 130 B ( 130 ) may instead be made as a single piece. A single piece first housing portion would obviate the need for the threaded portions  144 ,  146 . 
     The example closure  110  includes a second housing portion  140 . It is to be appreciated that the second housing portion  140  is actuatable with respect to the first housing portion  130 A/ 130 B ( 130 ) to provide an additional portion  132 A of the hollow interior  132 . Within an example, the additional portion  132 A of the hollow interior  132  is a volume to receive one or more additional line splice holder(s). 
     It is to be appreciated that the aspect of the second housing portion  140  being actuatable with respect to the first housing portion  130  to provide an additional portion  132 A of the hollow interior  132  is to be broadly interpreted. In general, the second housing portion  140  is involved in some activity (e.g., motion, attachment, or the like) relative to the first housing portion  130  such that the result is the provision of the additional portion  132 A of the hollow interior  132 . The present example closure  110  ( FIGS.  5 - 7   ) is provided as just an example of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. Other example closures discussed herein provide other examples of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. However, it is to be appreciated that such discussed examples need not be limitations upon the present disclosure and that other examples are contemplated and within the scope of the present disclosure. 
     The example closure  110  includes a coupling for connecting the second housing portion  140  to the first housing portion  130 , with the coupling connecting the second housing portion  140  to the first housing portion  130  in either of two positions.  FIG.  6    shows the second housing portion  140  connected to the first housing portion  130  in a first, closed, telescoped-in position.  FIG.  7    shows the second housing portion  140  connected to the first housing portion  130  in a second, open, telescoped-out position. The position of  FIG.  7    is telescoped outward relative to the position of  FIG.  6   . 
     Within the shown example of  FIGS.  5 - 7   , the coupling for connecting the second housing portion  140  to the first housing portion  130  are matting threaded portions. Moreover, the matting threaded portions may mate in different matting pairings. The first housing portion  130 , and specifically the second piece  1308  of the housing portion, has a male threaded portion  164 . The second housing portion  140  has two, spaced-apart female threaded portions  166 ,  168  within a hollow interior of the second housing portion. See  FIG.  8   . A first female threaded portion  166  is located adjacent to one end of the second housing portion  140  and a second female threaded portion  168  is located adjacent to a second end of the second housing portion. 
     In the first position of the second housing portion  140  relative to the first housing portion  130  (see  FIG.  6   ), the male threaded portion  164  of the first housing portion  130  is threadingly engaged with the first female threaded portion  166 . In the second position of the second housing portion  140  relative to the first housing portion  130  (see  FIG.  7   ), the male threaded portion  164  of the first housing portion  130  is threadingly engaged with the second female threaded portion  168 . In order to move from the first position to the second position, the male threaded portion  164  is unscrewed from the first female threaded portion  166 , then the second housing portion  140  is telescopingly slid outward relative to the first housing portion  130  and then the male threaded portion  164  is screwed into the second female threaded portion  168 . Of course, the use of threaded connections is just an example. The present disclosure is not limited to threaded connections and that variations in constructions and configurations are contemplated and within the scope of the present disclosure. For example, clamps, couplers, twist-locks, interfitting portions, etc. to hold the housing portions may be included within other examples that are within the scope of the present disclosure. 
     It is to be appreciated that the above discussed broad example is to provide a broad appreciation of the scope of the disclosure. It is to be appreciated that additional/different components/structures/features may be provided. As an example of such, the example of  FIGS.  5 - 7    is now further described to regarding additional components/structures/features.  FIG.  5    shows a cap  150  and two O-ring seals  152 ,  154  as additional components. 
     The first piece  130 A of the first housing portion  130  has an annular shoulder  160  encircling an entrance to the threaded portion  144 . The second housing portion  140  has an annular shoulder  162  encircling the end adjacent to the threaded portion  168 . The O-ring seal  152  is for seating against the annular shoulder  160  of the first housing portion  130 . When the second housing portion  140  is in the first position relative to the first housing portion  130 , via tightening the threaded portion  164  into the first threaded portion  166  of the second housing portion  140 , the O-ring seal  152  is also seated against the annular shoulder  162  of the second housing portion  140 . As such the O-ring seal  152  seals between the first and second housing portions  130 ,  410 . See  FIG.  6   . 
     Adjacent to the threaded portion  164  of the first housing portion  130  (i.e., upon the first piece  130 A), the O-ring seal  154  encircles the first housing portion  130 . It is to be noted that the threaded portion  164  has a larger diameter than the remainder of the first piece  130 A. See  FIG.  5   . As such, a base of the threaded portion  164  provides a shoulder-like structure against which the O-ring seal  154  is engaged. It is to be noted that the second threaded portion  168  of the second housing portion  140  has a radial diameter that is smaller than the adjacent inner wall of the second housing portion  140 . As such, a base of the threaded portion  164  provides a shoulder-like structure against which the O-ring seal  154  is engaged. 
     When the second housing portion  140  is in the second position (see  FIG.  7   ) relative to the first housing portion  130 , via tightening the threaded portion  164  into the second threaded portion  168  of the second housing portion  140 , the O-ring seal  154  is seated between the shoulder-like structure provided by the threaded portion  164  and the shoulder-like structure provided by the second threaded portion  168 . As such the O-ring seal  154  seals between the first and second housing portions  130 ,  140 . 
     It is to be noted that, due to the outward telescoping of the second housing portion  140  relative to the first housing portion  130 , an additional portion  132 A of the hollow interior  132  is made available. See  FIG.  5    within which the additional portion  32 A that is within the second housing portion  140  is visible (albeit due to the view being exploded). See that via a comparison of  FIG.  7    to  FIG.  6   , the additional portion  132 A of the hollow interior  132  is present within the example closure  110 . The additional portion  132 A of the hollow interior  132  is hidden from view within  FIG.  7    and thus is designated via use of a hidden-indicating lead line for the reference numeral  132 A within  FIG.  7   . As such, closure  110  is an example of a closure wherein the second housing portion  140  remains (i.e., is not removed) with the first housing portion  130  for a relatively smaller hollow interior (i.e., only  132 ) of the closure and a relatively larger hollow interior (i.e.,  132  and  132   a ) of the closure. 
       FIGS.  9 - 11    show an example closure  210  in accordance with at least one aspect of the present disclosure. The example closure  210  includes an ability to telescope to change volume size of a hollow interior  232  of the closure  210 . 
     The example closure  210  includes a first housing portion  230  enclosing at least a portion of the hollow interior  232  of the closure  210 . Within the shown example, the first housing portion  230  has a cylindrical shape. Within an example, at least one line splice holder, possibly the example line splice holder  22  ( FIG.  4   ), is to be located within the hollow interior  232 . The first housing portion  230  has a portal  234 . Within the shown example, the portal  234  is an open end (e.g., an opening) at an axial end of the cylindrical shape. Within an example, plural lines, such as the lines  20  shown within  FIG.  4   , extend into the hollow interior  232  through the portal  234 . It is to be appreciated that the portal  234  may receive structure (e.g., a cap, a plug or similar, such as shown as part of the other structure(s)  24  shown within  FIG.  4   . 
     The example closure  210  includes a second housing portion  240 . It is to be appreciated that the second housing portion  240  is actuatable with respect to the first housing portion  230  to provide an additional portion  232 A of the hollow interior  232 . Within an example, the additional portion  232 A of the hollow interior  232  is a volume to receive one or more additional line splice holder(s). 
     It is to be appreciated that the aspect of the second housing portion  240  being actuatable with respect to the first housing portion  230  to provide an additional portion  232 A of the hollow interior  232  is to be broadly interpreted. In general, the second housing portion  240  is involved in some activity (e.g., motion, attachment, or the like) relative to the first housing portion  230  such that the result is the provision of the additional portion  232 A of the hollow interior  232 . The present example closure  210  ( FIGS.  9 - 11   ) is provided as just an example of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. Other example closures discussed herein provide other examples of the aspect of a second housing portion being actuatable with respect to a first housing portion to provide an additional portion of a hollow interior. However, it is to be appreciated that such discussed examples need not be limitations upon the present disclosure and that other examples are contemplated and within the scope of the present disclosure. 
     The example closure  210  includes a coupling for connecting the second housing portion  240  to the first housing portion  230 , with the coupling connecting the second housing portion  240  to the first housing portion  230  in several selectable positions. It is to be appreciated that the variation among the selectable positions correlates to a variation of size of the additional portion  232 A of the hollow interior  232  that is provided by the second housing portion  240 . 
       FIG.  10    shows the second housing portion  240  connected to the first housing portion  230  in a first, closed, telescoped-in position. The first position generally is associated with the hollow interior  232  being at a smallest selectable volume. Such is associated with minimal volume size of the additional portion  232 A of the hollow interior  232  being provided by the second housing portion  240 . 
       FIG.  11    shows the second housing portion  240  connected to the first housing portion  230  in a second, open, telescoped-out position. The position of  FIG.  11    is telescoped outward relative to the position of  FIG.  10   . The second position generally is associated with the hollow interior  232  being at a largest selectable volume. Such is associated with maximum volume size of the additional portion  232 A of the hollow interior  232  being provided by the second housing portion  240 . 
     Within the shown example of  FIGS.  9 - 11   , the coupling for connecting the second housing portion  240  to the first housing portion  230  includes a slip-joint compression fitting  256 . The fitting  256  includes a segment of the second housing portion  240  that has a male threaded portion  258  ( FIG.  9   ), and within the male threaded portion  258  is a concave annular face  260 . 
     The fitting  256  also includes a collar  270  and an O-ring annular seal  272 . Both of the collar  270  and an O-ring annular seal  272  are sized to circumscribe a smooth cylindrical outer surface  236  of the first housing portion  230 . The O-ring annular seal  272  fits around the cylindrical surface  236  of the first housing portion  230  with a relatively tight fit. Moreover, the O-ring annular seal  272  may have a cross-sectional profile that has a portion that generally mates to the concave annular face  260  on the second housing portion  240 . 
     The collar  270  has a partial hollowness that envelopes the O-ring annular seal  272 . Also, the collar  270  has a female threaded portion  284  (shown via a hidden-indicating lead line for the reference numeral) within such partial hollowness of the collar  270 . The female threaded portion  284  mates within the male threaded portion  258  on the second housing portion  240 . When the female threaded portion  284  is tightened onto the male threaded portion  258 , the O-ring annular seal  272  is compressed against the concave annular face  260  on the second housing portion  240 . Such compression also causes the O-ring annular seal  272  to press against the cylindrical surface  236  of the first housing portion  230 . Thus, the O-ring annular seal  272  seals between the first and second housing portions  230 ,  240  and helps to hold the first and second housing portions  230 ,  240  relative to each other. 
     Loosening of the collar  270  (i.e., loosening of the female threaded portion  284  relative to the male threaded portion  258 ), allows the O-ring annular seal  272  to relax and reduces the compression of the O-ring annular seal  272  against the concave annular face  260  and the cylindrical surface  236  of the first housing portion  230 . Within the compression reduced, the second housing portion  140 , and the collar  270  and O-ring annular seal  272 , may be moved (i.e., slid) relative to the first housing portion  230 . The first and second housing portions  230 ,  240  may relatively slide, in a telescope manner, to any of the selectable positions, including the first position ( FIG.  10   ) and the second position ( FIG.  11   ). As such, closure  210  is an example of a closure wherein the second housing portion  240  remains (i.e., is not removed) with the first housing portion  230  for a relatively smaller hollow interior (i.e., only  232 ) of the closure and a relatively larger hollow interior (i.e.,  232  and  232   a ) of the closure. Again, it is to be appreciated that the use of threaded portions provides just an example and that other examples, which include other constructions and configurations (e.g., other/additional portions) for connection of the housing portions, are within the scope of the present disclosure. For example, collars, clamps, twist-locks, interfitting portions, etc. to hold the housing portions may be included within other examples that are within the scope of the present disclosure.
