Most promotional gadgets do one thing. A shaker mixes protein, a lunchbox holds a meal, a water bottle carries water. The 2in1 container does two: the same body with two interchangeable lids works once as a shaker, and once as a leak-proof food container. For a brand that hands it out with its own logo, it is a gadget with dual utility — and therefore a double chance of staying in daily circulation.
This article explains how the 2in1 container works, who it is suitable for as a promotional product, and how to order it with a print.
How the 2in1 design works
The basis is one body – the same as in a shaker – and two interchangeable lids. With the drinking cap, with a spout, it is ShakerX – a mode for mixing protein and drinks. With the flat lid, the same body becomes ContainerX – a leak-proof meal container. One product, two functions, depending on which lid you put on.
In a few seconds, you decide what the product should be at any given moment. In the morning, a shaker for post-workout protein, at noon, a container for a salad or oatmeal for work. One item in your bag instead of two.
For the user, it is a real simplification. For the brand that brands it, it is a gadget that stays in use longer and in more situations – and each of them is contact with the logo.
The body and both lids are made of food-grade polypropylene (PP) – the same material we use to produce our shakers. The product is entirely our own design, manufactured in Poland using our own molds – it is not rebranded import, but an original construction. Available capacities are 400 ml and 700 ml.
Mixing without a ball or a strainer
In shaker mode, the design is based on Circle Technology – the rounded bottom and smooth inner surface ensure that the protein mixes without dead zones where powder would clump. No ball, no strainer.
This matters doubly with a 2in1 product. The lack of moving parts means not only a smoother mix but also fewer parts to wash and no ball that could fall out and get lost. A product that also serves as a food container must be easy to keep clean – and fewer elements mean simpler hygiene.
Who is it suitable for as a promotional gadget
We carry out the printing using the screen printing technique, around the body – the graphic covers an area practically the entire circumference (only a narrow strip with the scale is omitted). This provides a large, visible advertising surface regardless of how the container sits on the desk or is held in the hand.
The price of the print depends solely on the number of colors, not the size of the graphic. A logo stretched across the entire area costs the same as a small logo on the side. We standardly work in 1–3 colors; each additional one is a fixed surcharge.
Logo printing
With plastic shakers that come into contact with drinks, material documentation is not a whim, but a protection for your brand and the user.
Our shakers are produced using plastic with a PZH certificate – a hygienic certificate issued by the National Institute of Public Health, confirming the material is approved for contact with food. We provide the document upon order.
When evaluating any supplier, look for a declaration of compliance with EU regulations — Regulation (EC) No 1935/2004 — or a PZH certificate as additional confirmation. Lack of documentation is a complaint and image risk, especially when the product reaches your brand’s customers.
Material documentation
For a product that comes into contact with both drinks and food, material documentation has double significance. Our container has a full set:
- Declaration of compliance for food contact (EU regulations 1935/2004 and 10/2011, Good Manufacturing Practice GMP)
- Migration tests performed in an accredited laboratory (J.S. Hamilton) – result compliant with standards
- REACH compliance – no substances from the SVHC list above the threshold
- PPWR compliance (EU regulation 2025/40 on packaging) along with recyclability
- Production in a facility with ISO 9001:2015 and BRCGS
certificates
This is the documentation we provide upon order — ready to be attached to purchasing documentation if your purchasing department requires it.
MOQ and ordering
The minimum order is one carton: 60 pieces for 400 ml, 56 for 700 ml. Subsequent ones in multiples of the carton. A low entry threshold allows testing the product without a large initial investment.
Lead time: from 7 business days from approval of the visualization. We prepare the visualization free of charge within 24 hours of sending the logo.
How to order
- Brief – logo in vector (AI, EPS, PDF), capacity, lid color
- Free visualization in 24 hours – preview before commitment
- Approval – check readability and contrast
- Production and delivery – from 7 business days
Summary
The 2in1 container is a shaker and lunchbox in one body with two interchangeable lids. For a brand that hands it out with a logo, it is a gadget with dual use – used more often and in more situations than a regular shaker, and therefore working longer for brand recognition.
Full food contact documentation, mixing without a ball, and a low order threshold make it work well both as merch and as a product added to an offer.
Send your logo and choose the capacity – you will see the visualization tomorrow.
