Instructions
Basics
Rinse before first use. Unscrew cap to access large fill opening. Squeeze bottle slightly from the sides to open up the bottle, then fill with any soap or paste. Screw cap on tightly to fully engage seal. Snap-top cap lid will align with the front of the bottle when properly tightened. Flip lid open to dispense contents. Write in contents on the snap loop with permanent marker.
Filling
Make sure the cap is screwed on completely after filling. When properly tightened, there will be no obvious gap between the bottle and cap. The front of the flip cap should squarely align with the front of the bottle when fully tightened.
FlatPak bottles will work with toothpaste. Fill the bottle with toothpaste by firmly pressing the opening of the toothpaste tube against the large fill opening to form a seal. While firmly pressing the two ends together, squeeze the toothpaste tube so the contents are transferred into the bottle.
To fill the bottle with fluids (sunscreen or soap) first unscrew the cap to access the large fill opening. Then squeeze the fabric bottle from the sides to open up the cavity and pump, squeeze, or pour the desired contents in through the large fill opening. You may need to shake the contents down to the bottom of the bottle a time or two during filling if the fluid has a high viscosity.
If the bottle still has a little fluid inside that is causing the fabric walls to stick together, simply pinch the fabric on opposing flat sides of the bottle and pull the walls apart to open up the bottle cavity for refilling.
Washing
Wash the bottle by hand only. Fill with warm water and massage from the outside to clean the bottle. Do not wash the bottle in a dishwasher or washing machine.
Tips
Chemical Compatibility
FlatPak bottles are compatible with the vast array of cosmetic creams, pastes, and fluids on the market. While many have been tested, it's virtually impossible to keep up with the ever-changing array of ingredients, chemicals, and compounds used in cosmetic products. As with all toiletry bottles, there is a chance that an ingredient in one of your cosmetic products could damage the bottle material.
Chemicals currently known to damage the bottle include: Ethanol (drinking alcohol), which may be listed in cosmetics as "ethyl alcohol"
Alcoholic Beverages
Under no circumstances should this product be used to store or transport alcoholic beverages. Ethanol (alcohol found in beer, wine, and spirits) can attack and destroy the lining of the bottles. Use of this product to carry alcoholic beverages (ethanol) will void the warranty.
Food or Drink
These bottles are not certified to carry food or drink products.
Scrubbing Soaps
When using soaps that contain pumice or other granular media, rinse the open lid before snapping it shut. This granular media suspended within the soap can interfere with the snap closure and cause the lid to be difficult to close if not rinsed away first. Forcing the lid closed with pumice or granular media in the closure can damage the lid. This abuse is not covered under warranty.
Peace-of-Mind
FlatPak bottles are made from some of the industry’s most durable materials and construction methods. The lid snap is also engineered to prevent/minimize accidental openings. However, it’s impossible to predict what can happen when you’re on the road or trail. We recommend you put your toiletry bottles in a plastic ziplock bag for that extra bit of insurance.
The fluid dried up inside the bottle
Some drying may occur if you use a FlatPak bottle for long-term storage of a fluid. This is a common occurrence with toiletry bottles. If the contents thicken or harden over time, simply add a little warm water and massage the bottle from the outside until it softens up. Repeat as needed. Storing the FlatPak bottle in a plastic ziplock bag can help prevent the contents from drying during those long storage periods.
The hinge on the lid turned white and I'm worried it may break
Don't worry, this is totally normal. This type of hinge is called a "living hinge" and it’s normal for them to turn white when they’re made from dark colored plastic. When the hinge is bent for the first time the plastic stretches and the distance between the dye particulates in the plastic increases, causing the color to lighten. This hinge is very durable and will last for thousands and thousands of uses.
