Buyer guide
A practical checklist for choosing trigger-spray capping equipment, cap feeding routes and automation level.
Step 1
Trigger sprayers are awkward because the body is asymmetric and the dip tube can bend. The machine must be selected around the real cap sample, not just a catalogue diameter. Check cap diameter, trigger body width, tube length, tube stiffness and how the closure arrives at the machine.
Where caps are inconsistent, a bowl feeder, elevator, gripper or tube straightening system can make more difference than a higher headline speed.
Lower-cost route for smaller batches where the operator places caps before tightening.
Useful where trigger caps need sorting, orientation and controlled presentation.
Best for larger outputs where cap feeding, placement, tube handling and tightening are part of the same line.
Checklist
Diameter, height, weight, shape, material, shoulder design and stability through conveyor guides.
Trigger body size, cap diameter, tube length, tube stiffness, thread style and closure torque expectation.
Target bottles per minute, operator loading method, shift pattern and future capacity plans.
Existing filler, conveyor height, labeller, coding, accumulation and available air and electrical services.
Compare machines
Automatic trigger-sprayer capping system for cleaning, care and chemical bottles requiring stable cap presentation and repeatable closure control.
Vibratory bowl trigger-spray cap feeding and placement equipment for bottles with soft dip tubes and awkward trigger closure geometry.
High-speed inline belt/spindle screw capper for round plastic bottles, with guided side-belt transport and cap feeding options.
Pneumatic inline screw capping machine for spray, pump and screw-cap bottles with adjustable fixtures and repeatable torque control.
URS essentials
Before comparing models, convert the production need into a short user requirement specification. This prevents a generic capper from being selected without the feeding, tube handling or bottle support the real pack needs.
Sustained accepted output, pack quality, operating hours, changeover frequency and required availability.
Complete bottle, closure and tube matrix with drawings, samples and tolerances.
Space, access, utilities, cleaning, product risk, guarding and integration with existing equipment.
Factory and site tests, run duration, sample set, quality checks, documentation and training.
