The quest for perfect food storage is a never-ending battle against stale crackers, weevil-infested flour, and the dreaded freezer burn. In this pursuit, OXO Pop containers have emerged as a popular contender, promising airtight seals and organized pantries. But do they truly live up to the hype? Let’s delve deep into the world of OXO Pop containers to uncover the truth about their airtight claims, design features, and overall performance.
Understanding Airtightness: What It Really Means
Before we examine the specifics of OXO Pop containers, it’s crucial to define what “airtight” really means in the context of food storage. Airtight containers are designed to prevent the exchange of air between the inside and outside environments. This barrier helps to preserve the freshness, flavor, and texture of food by preventing oxidation, moisture absorption, and pest intrusion.
Not all airtight containers are created equal. The level of airtightness can vary depending on the design, materials, and sealing mechanism. Some containers might offer a near-perfect seal, while others might allow a minimal amount of air exchange. Understanding these nuances is crucial for making informed decisions about food storage.
The OXO Pop Container Design: A Closer Look
OXO Pop containers are distinguished by their sleek, modular design and signature push-button mechanism. This button, when pressed, expands a silicone gasket inside the lid, creating a seal against the container’s rim. The rounded corners and straight edges of the containers also contribute to efficient stacking and space utilization.
The containers are typically made from BPA-free plastic, which is known for its durability and clarity. The clear construction allows for easy identification of contents, eliminating the need for labels in many cases. OXO offers a variety of sizes and shapes to accommodate different types of food and pantry configurations.
The Push-Button Mechanism: How Does It Work?
The heart of the OXO Pop container’s airtight design is the push-button mechanism. When you press the button, it pushes a plate downwards, causing a silicone gasket located around the rim of the lid to expand outwards and create a tight seal against the container’s body. Releasing the button retracts the gasket, allowing you to easily remove the lid.
This system aims for a simple and user-friendly way to achieve an airtight seal. The pressure created by the expanding gasket is intended to be strong enough to prevent air and moisture from entering the container.
Materials Used in OXO Pop Containers
OXO Pop containers are primarily constructed from BPA-free plastic, specifically acrylonitrile styrene (AS) plastic for the bodies and acrylonitrile butadiene styrene (ABS) plastic for the lids and button components. The gasket is made from silicone.
- BPA-free Plastic (AS & ABS): Offers durability, clarity, and resistance to impact. It is also food-safe and doesn’t leach harmful chemicals into the food.
- Silicone Gasket: Provides flexibility and a tight seal, crucial for preventing air and moisture exchange.
The choice of these materials contributes to the overall functionality and longevity of the containers.
OXO Pop Containers: Testing the Airtight Claim
To determine whether OXO Pop containers truly live up to their airtight claims, let’s examine various testing methods and real-world user experiences.
The Water Test: Can They Hold Liquids?
One simple test to assess airtightness is the water test. This involves filling the container with water, sealing it, and turning it upside down. If water leaks out, the seal is not airtight.
