A hollow, cylindrical clutch adapter that surrounds a screw-on end cap and prevents the transfer of excessive torquing forces to the end cap so as to avoid over-tightening the end cap to a threaded neck of a fluid reservoir, such as that common to a squeeze bottle. The squeeze bottle includes an outer body that surrounds the fluid reservoir and a hollow head that surrounds the clutch adapter and is rotatable relative to the outer body. The clutch adapter includes a series of parallel aligned splines or teeth projecting radially inward thereof so as to be respectively interspersed between the usual ridges that are molded into the end cap, whereby to insure that a rotational force applied to the clutch adapter will be transmitted to the end cap. The hollow head is rotated to apply a corresponding rotational force to the end cap via the clutch adapter located therebetween. Once the end cap has been sufficiently tightened against the neck of the fluid reservoir, any further rotation of the head will cause the clutch adapter affixed thereto to slip and rotate around the end cap, such that excessive torquing forces that are applied to the head will be dissipated by the clutch adapter.

[ Having set forth the preferred embodiment, what is claimed is:] [1.] A combination, comprising:a fluid reservoir having an open neck extending outwardly therefrom, said neck having a screw threaded end at which to receive a correspondingly screw threaded end cap so as to close said neck;a hollow clutch adapter being a hollow body with two open ends, said clutch adapter surrounding the end cap, said clutch adapter having means extending inwardly thereof by which to engage the end cap such that a rotational force applied to said clutch adapter is imparted to the end cap to cause the end cap to be rotated into tightened engagement against the screw threaded end of said neck of said fluid reservoir, said clutch adapter being adapted to rotate around the end cap once the end cap is rotated into tightened engagement against said neck to prevent an over-tightening of the end cap against said neck in response to a continued rotation of said clutch adapter;a hollow head surrounding said clutch adapter and affixed thereto, such that a rotational force applied to said hollow head is imparted to the end cap by way of said clutch adapter so as to cause the end cap to be rotated into tightened engagement against the screw threaded end of said neck of said fluid reservoir; anda hollow outer body having first and second openings formed therein and surrounding said fluid reservoir, said hollow head being rotatable relative to said hollow outer body,said hollow outer body and said fluid reservoir being flexible so that a compressive force applied to said hollow outer body is transferred to said fluid reservoir to compress said fluid reservoir, said flexible fluid reservoir being compressed and pushed through said first opening in said hollow outer body so as to be surrounded by said hollow outer body such that the neck of said fluid reservoir projects outwardly from said hollow outer body via said second opening formed therein.
