We are Yuyao Shangjia Plastic Industry Co., Ltd., a Mini Trigger Sprayer manufacturer based in China. Our compact trigger sprayers support cleaning, disinfection, sanitising and home-care packaging where precise dosing, leak-resistant sealing and a small bottle footprint are priorities. With wholly owned subsidiary Yuyao Shuangyu Automation Technology Co., Ltd., we combine mould development, automated production and quality management in one R&D-to-delivery system.
This range sits alongside our Trigger Sprayer family. Standard trigger sprayers suit larger bottles and multi-purpose cleaning concentrates; mini trigger sprayers answer the need for travel-size packs, retail samples, hand-held surface sprays and smaller daily-use formats.
Compact Trigger Sprayer Range
Our mini range is built around four SJ109 models. Each uses a compact PP-based construction but differs in actuation style and body geometry. We select the configuration according to the bottle, the liquid and how the end user holds the pack.

For each model we confirm the neck finish, dip tube length, output volume per stroke and nozzle behaviour before we prepare a formal proposal.
Application and Material Fit
Mini trigger sprayers are specified wherever a controlled amount of liquid has to be applied repeatedly: household cleaners, kitchen and bathroom sprays, disinfectants, glass cleaners, plant care and small-format daily-care products.
The compact body helps avoid waste by delivering a consistent dose, while the sealed assembly reduces spillage during storage, transport and travel.
- Water-based cleaning and disinfecting formulas are the usual fit for PP-bodied mini sprayers.
- Liquids containing aggressive solvents, high fragrance loads or strong acids need a material compatibility review before moulding.
- For atomised coverage, we confirm the nozzle insert and spray pattern against the product's application surface.
- For splash-free application in small packs, we can adjust the flow rate and trigger return force.
Critical Specifications and Configuration
The trigger sprayer is only one half of a dosing system; the bottle, closure and dip tube must match the whole pack. We use the following criteria to define the production configuration.
- Neck finish and thread size so the sprayer fits the customer's bottle without cross-threading.
- Dip tube length relative to bottle height, base geometry and internal ribs.
- Output volume per stroke and discharge pattern: mist, stream or a combined pattern.
- Actuator style and trigger or button force, including return behaviour and ergonomics.
- Nozzle position, open or closed convenience and any leak-resistant sealing requirement.
- Colour, gloss level and branding application for the finished assembly.
Customization and Sample Proofing
Our R&D team supports customized moulds for different bottle geometries, actuator styles and design details. The flow is straightforward: we confirm your product requirements, prepare structural and appearance drawings, then produce a customized sample for your inspection.
- Requirement confirmation: product type, size, appearance, use scenario and order quantity.
- Sample design: structural and appearance drawings for your feedback.
- Revision and mass production: sample approval followed by serial production with functional checks.
- Delivery and follow-up: finished packaging, timely shipment and long-term support for repeat orders.
Quality, Automation and Line Integration
We run production under a quality control system aligned with ISO and CE requirements. Checks focus on leak-free sealing, smooth trigger or button return, output consistency, spray pattern and surface appearance.
Our subsidiary Shuangyu Automation supports product R&D and automated production, allowing us to keep assembly and inspection consistent across large order volumes.
- Components are supplied ready for automated or manual filling and capping lines.
- Neck finish, dip tube length, actuator orientation and packaging quantity are confirmed before release.
- Outer carton, palletization and export marking requirements are agreed at order acknowledgement.
Information We Use to Configure Your Solution
To prepare a precise configuration and quotation, our engineers need the following project inputs.
- Target application and filling environment: household, disinfection, personal care or another category.
- Bottle details: neck finish, capacity, height, base profile and available headroom.
- Liquid properties: viscosity, chemical family, solvent or fragrance content and filling temperature.
- Functional targets: output per stroke, spray pattern, leak resistance and actuation force.
- Appearance requirements: colour, finish, logo, sample photo or reference drawing.
- Commercial quantities, packaging format and delivery destination.
With these details, we confirm the model, material, dip tube, nozzle and decoration options before sending drawings and a sample.
Mini Trigger Sprayer FAQs
What liquids work in a mini trigger sprayer?
Water-based cleaners, disinfectants, glass cleaners and diluted daily-care liquids are the common fit. Aggressive solvents or high-acid formulas should be checked against PP compatibility first.
What is the difference between trigger-style and button-style mini sprayers?
Trigger-style models give a longer lever stroke and familiar two-finger control. Button-style models keep the head profile more compact and suit one-finger actuation on narrow bottles.
Can you customise colours, branding and moulds?
Yes. We offer custom moulds through our R&D team, plus colour, surface finish and branding options. A structural drawing is prepared before sample production.
What details do you need for a quotation?
We need the bottle neck finish, bottle dimensions, liquid type, output per stroke, spray pattern, colour and branding requirements, estimated quantity and delivery preferences.
Is a sample available before mass production?
Yes. Our standard flow includes customized samples for inspection and feedback. Mass production starts only after the sample is approved.
