Abstract
The disclosure relates to a fluid dispensing device including: a housing including an orifice and configured to accommodate a portion of a spray delivery device including an outlet, a protective cap configured to accommodate the outlet of the spray delivery device and including a cap portion, wherein the protective cap is configured for fitting to the housing so that the cap portion covers the orifice, a biasing member transferable between a pre-loaded state and an unloaded state and configured to store energy in the pre-loaded state to produce a discharge of the spray delivery device, a releasable interlock configured to retain the biasing member in the pre-loaded state, a trigger engaged with the interlock and configured to release the interlock when actuated, wherein release of the energy stored in the pre-loaded biasing member is prevented as long as the cap portion covers the orifice.
Core Innovation
The invention relates to a pre-loadable fluid dispensing device, including a housing with an orifice configured to accommodate at least a portion of a spray delivery device with an outlet through which fluid stored in the spray delivery device is dischargeable. A protective cap defines an interior space configured to accommodate the outlet of the spray delivery device and includes a cap portion configured to cover the orifice in a closing position relative to the housing.
A mechanical spring is reversibly transferable between a pre-loaded state and an unloaded state and is configured to store mechanical energy in the pre-loaded state effective to produce a spray discharge of the spray delivery device. A releasable interlock is configured to retain the mechanical spring in the pre-loaded state, and a mechanical coupling member engaged with the mechanical spring is displaceable relative to the housing into a preload position against an action of the mechanical spring effective to transfer the mechanical spring into the pre-loaded state.
A manually actuatable trigger is operationally engaged with the releasable interlock and configured to release the releasable interlock when actuated. The protective cap is transferable into an opening position relative to the housing and is operable to actuate the manually actuatable trigger as the protective cap approaches or reaches the opening position, while the protective cap is operably engageable with the mechanical coupling member and displaceable into the preload position against the action of the mechanical spring when approaching the closing position relative to the housing.
Claims Coverage
The relevant material identifies one independent claim, centered on a mechanically pre-loadable, cap-actuated releasable interlock and spring coupling arrangement for a spray delivery device outlet discharging through a housing orifice.
Cap actuates manually actuatable trigger and releases interlock during opening
The protective cap is transferable into an opening position relative to the housing and is operable to actuate the manually actuatable trigger as the protective cap approaches or reaches the opening position, thereby releasing the releasable interlock when actuated.
Protective cap engages mechanical coupling member to preload spring
The protective cap is operably engageable with the mechanical coupling member and is operable to displace the mechanical coupling member into the preload position against the action of the mechanical spring when approaching the closing position relative to the housing.
Protective cap covers housing orifice in closing position with interior space
The protective cap defines an interior space configured to accommodate the outlet of the spray delivery device and comprises at least a cap portion configured for fitting to the housing in a closing position relative to the housing, in which the cap portion covers the orifice.
Releasable interlock retains reversibly transferable spring in pre-loaded state
A mechanical spring is reversibly transferable between a pre-loaded state and an unloaded state and stores mechanical energy in the pre-loaded state effective to produce a spray discharge, and a releasable interlock retains the mechanical spring in the pre-loaded state.
Mechanical coupling member transfers spring into pre-loaded preload position
A mechanical coupling member engaged with the mechanical spring is displaceable relative to the housing into a preload position against an action of the mechanical spring effective to transfer the mechanical spring into the pre-loaded state.
Housing/orifice accommodates spray delivery device portion with discharging outlet
The housing comprises an orifice and is configured to accommodate at least a portion of a spray delivery device comprising an outlet through which a fluid stored in the spray delivery device is dischargeable.
Across the independent claim structure, coverage centers on a protective cap that both covers the housing orifice in a closing position and, when moved toward opening, actuates a manually actuatable trigger to release a releasable interlock retaining a spring in a pre-loaded state. The cap is also engaged with a mechanical coupling member to displace it into a preload position against the spring action, enabling spring energy transfer to drive spray discharge through the spray delivery device outlet.
