Vacuum containers made of plastic are well liked for being easy to carry and affordable. However, as with any item they may encounter problems with prolonged usage over time. It is important to be aware of the issues that may arise with these containers, in order to effectively handle and look after them. This blog aims to provide guidance on identifying problems, troubleshooting methods and maintenance suggestions to ensure your container remains in good working condition for a prolonged period.
Common Issues with Plastic Body Vacuum Flasks
When opting for a vacuum flask body choice is usually a trade-off between affordability and practicality, factors to consider carefully as these flasks are prone to specific issues impacting their functionality. Being aware of these typical concerns enables you to maintain your flask better.
Material Degradation
With time, despite their usual resistance, components in vacuum flasks can wear out because of several factors: heat, some cleaning products or sunlight rays. Signs of degradation include brittleness or discoloration of the material, which is often accompanied by the appearance of tiny cracks on its surface. These changes can compromise the strength of the flask and its ability to keep liquids at a certain temperature. Cheaper plastic materials may not retain heat as well as metal parts and can deteriorate faster, affecting performance over time.
Temperature Sensitivity
While designed to put up with the temperature of hot and cold liquids, plastic is much more sensitive to temperature when compared to stainless steel. It could even break or warp with extremes of both hot and cold. Besides, frequently exposing it to such drastic temperature differences would weaken the plastic hence turning it into something much more breakable. As such, taking this advantage may result in some harm to your flask in the microwave or freezer..
Sealing Problems
A key function of a thermos flask is to preserve the temperature of its contents over time by creating a seal to prevent heat loss effectively. In the case of plastic bodied thermos flasks specifically, you might face problems with the lid not fitting properly or with the gaskets becoming worn out or damaged over time. The presence of debris or residue on the sealing surfaces can also hinder a seal from forming adequately. Even a minute gap can result in heat dissipation and reduce the flask’s capacity to retain its contents at an optimal temperature.
Troubleshooting Common Problems
After pinpointing issues, with plastic body thermoses and vacuum flasks, it’s helpful to know how you can address them. The actions you choose can prevent you from needing to buy ones needlessly and allow you to maximize the use of your flask.
Identifying Cracks and Damage
Make sure you inspect your flask thoroughly for any cracks or dents and check the body and bottom carefully as these are spots for damage to occur! Look out for cracks that may be hard to spot at first glance and any discolored or brittle areas too since they can affect the vacuum seal of the flask! If you spot any damage in your flask, it could be a sign that it’s time to get one.
Addressing Leaks
Leaks are a problem that often stems from a defective lid or gasket in your container or flask. Take a look at the lid to make sure it’s securely and properly fastened. Inspect the rubber or silicone gasket for maintaining a snug seal, if your flask has one and ensure it’s not worn out or damaged. If you find any issues with the gasket’s condition, you might be able to locate a replacement for it. At times, the rubber ring may be taken off for cleaning and not reinstalled correctly. Try reinstalling it and ensuring that it’s properly in place without any leaks present. There is a possibility that the presence of dirt or residue on the sealing surfaces could be contributing to the leakage issue.
Dealing with Odors and Stains
Plastic containers may hold onto smells or marks from the drinks you put in them over time. If you feel that your container has some lingering smell, then it is a good idea to clean it with baking soda and water. The stains can be taken out with the help of a solution of white vinegar and warm water. Allow the cleaning solution to stay inside the container for some time before washing it out. You can also use a bottle brush for cleaning from the inside. Regular cleaning stops the building up of substances that invite odors and marks.
Maintaining and Caring for Your Plastic Body Vacuum Flask
Ensuring your body vacuum flask lasts long requires proper upkeep and care practices to maintain its quality. Follow these cleaning and storage instructions to preserve the condition of your flask.
Cleaning Techniques
To clean your plastic vacuum flask body effectively, safely use warm water and dish soap instead of harsh chemicals like chlorine and bleach, which might harm the plastic material and insulation inside the flask itself. It’s recommended to use a sponge or bottle brush when cleaning the inside of the flask with special attention to the lid and sealing areas, ensuring to rinse all parts properly to remove any soap residue thoroughly.
Storage Best Practices
Before you store your plastic body vacuum flask away for storage purposes, ensure it is completely dry to avoid mold or bacterial growth caused by moisture accumulation inside the flask. Store the flask with the lid off to allow air circulation and prevent any foul odors from developing. Also remember to keep your flask away from direct sunlight or extreme temperatures, as they can cause the plastic material to deteriorate over time.
When to Consider Replacement
When you start noticing cracks appearing on its surface or consistent leaks happening frequently or witness a decline in the quality of the plastic material over time, then it’s a good idea to consider getting a new one. Using a damaged flask continuously may bring about health hazards, especially when the insulation is compromised in any way or the vacuum seal doesn’t work properly anymore.
