DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The waterpillow 2 shown in Figure 1 has the tubular funnel member 30 which can be threadably received in the threaded port 10 for adding or removing water.
The threaded plug 12 is used to releasably close the port 10.
As shown in Figure 3, the funnel serves a number of purposes in the present design but is particularly useful in filling of the water envelope within the pillow without any substantial spillage and/or allows water to be easily removed from the water retaining envelope. The end user adds or removes water to adjust the pillow accordingly to achieve the desired support. Water 5 is poured from the pitcher 3 and passes through the funnel into the pillow.
The waterpillow 2 has an outer fabric casing 4 and 30 a water retaining envelope (not shown) positioned with the casing 4 and located at a bottom surface of the pillow. A compressible fill material is supported above the water retaining envelope. A closure system 8, on the bottom of the pillow, allows water to be added or removed from the envelope and comprises a threaded port 10 sealed to the envelope and open to the exterior of the pillow.
A threaded plug 12 is releasably received in the port 10.
W~3-11 528 Details of the pillow construction are shown in U.S.
Patent 4,847,931.
A purchaser of the pillow will add the desired amount of water to the envelope. The amount of water varies the firmness of the pillow and some trial and error is required. Basically, the user refers to a firmness chart and selects the desired firmness having a specified volume of water to be added to the pillow. The amount of water is then measured using a measuring cup or other measuring device and added to the envelope through the port 10. The port 10 is of a thin profile as is the threaded plug 12. Water can be carefully added directly through the port 10, however, some skill and dexterity is required.
To overcome this problem as shown in Figure 2, the tubular funnel 30 is threaded into the open port 10 and preferably forms a watertight connection with the port.
The user can then pour the water through the tubular body member 34 and the water will pass into the envelope. The tubular body 34 also allows the user to grasp the funnel and hold the funnel and the connected port in a~desired position for water to be added. The funnel is preferably several inches tall and thus provides a convenient grasping surface. Similarly the open mouth 31 of the tubular member is preferably at least one and one half inches to ease the addition of water to the envelope through the substantially smaller outlet port. Once water has been added to the envelope, the pillow can be supported on a flat surface and the user can push down on the pillow and/or funnel to allow air to be bled from the envelope. It is desired to remove as much air as possible and the funnel provides a simple means to allow adjustment in the envelope and bleeding of the air without spillage of the water about the port 10.
_ 5 _ W~-11 528 Once the desired amount of water has been added, the funnel may be released from the pillow by a counterclockwise rotation. Once the funnel has been removed, the threaded plug l2 is threaded into the port 10 to seal the envelope. In many cases, there is no further need to adjust the water in the pillow. In other cases, the degree of firmness requires adjustment and the user can vary the firmness by adding or removing water.
The tubular funnel 30 can act as a tool for assisting in removal of the threaded plug 12 which in some cases is difficult to remove. The funnel on its lower surface includes a narrow end 40 which is receivable within the recessed cavity 16 of the plug 12 (See Figure 7). This narrow end includes a downwardly opening channel 42 which straddles the grip bar 14 of the plug. Once the funnel has been inserted in the cavity 16 of the plug, with the channel 42 either side of the grip bar 14, the funnel can be rotated counterclockwise to remove the plug 12 from the threaded port 10. Once the plug has been removed, the funnel can then be threaded into the port 10 and water can be added to the envelope as previously described.
In some cases, it may be desirable to remove a certain amount of water from the envelope and in this case, the tubular funnel 30 can act as a spout to allow some of the water to be removed. In this way, the outer casing 4 of the pillow remains out of contact with the water and the user has a convenient way to add or remove water from the pillow.
After the above step, the funnel can then be removed from the port by counterclockwise rotation of the tubular member and the plug 12 reinserted. Some users may wish to use the funnel to again engage the plug and allow tightening of the plug by rotation of the funnel in WF~-11 528 ' a clockwise rotation. The plug has an O-ring seal to avoid leakage and some compression thereof is required.
With this, arrangement, problems associated with filling and/or removing water from the envelope are overcome. Any users who previously experience difficulty in engaging the threaded plug 16 merely use the funnel as a tool to engage the plug and act as a handle or extension of the plug for tightening or removal of the plug.
The funnel 30, as shown in Figure 4,has a reduced end 40 located below the exterior threads 32 and below the outwardly extending flange 36. The narrow end 40 serves to separate the two sides of the envelope which have a tendency to collapse on one another. Furthermore, the user tends to lift up on the funnel separating the two sides of the envelope and allowing water to easily fill the envelope. The flange 36 acts as a stop surface limiting the degree the funnel is threaded into the port 12. The bottom surface of the funnel is divided into two outlets 38 by the downwardly opening channel 42.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.

Some users may wish to use the funnel to again engage the plug and allow tightening of the plug by rotation of the funnel in WF~-11 528 ' a clockwise rotation. The plug has an O-ring seal to avoid leakage and some compression thereof is required.
With this, arrangement, problems associated with filling and/or removing water from the envelope are overcome. Any users who previously experience difficulty in engaging the threaded plug 16 merely use the funnel as a tool to engage the plug and act as a handle or extension of the plug for tightening or removal of the plug.
The funnel 30, as shown in Figure 4,has a reduced end 40 located below the exterior threads 32 and below the outwardly extending flange 36. The narrow end 40 serves to separate the two sides of the envelope which have a tendency to collapse on one another.
