Stackable container with secure sealing

Abstract

The present invention relates to a stackable container for items, such as food, comprising a base and lid with secure sealing mechanisms. Each of the base and lid comprises corresponding three rims and three edges being mateable to provide multiple layers of sealing mechanisms to ensure durable sealing. The lid further comprises a sealing lip for locking the lid onto the base and for providing another layer of sealing. Each of the base and lid further comprises partially planar raised portions and further raised portion around the outer perimeter of the planar raised portions for providing stable stacking mechanism. The lid further comprises a tab for assisting a user to open the lid without spoilage.

Description

FIELD OF THE INVENTION[0001]The invention relates to a stackable container for storing and transporting items such as food with tight secure sealing mechanism between a container base and detachable lid with a tab for ease of detaching the lid.BACKGROUND OF THE INVENTION[0002]Containers are used for storing and transporting items such as food for many different commercial and home applications. For commercial application, such as fast food or take-out restaurant, it is important that the containers provide tight and durable sealing mechanisms between container base and detachable lid to ensure and avoid leakage and / or spoilage and to keep away the contents from contamination. While providing secure and durable sealing mechanism, it is also important to provide a way to easily detach or open the lid. Lid can be detached and attached to the base for a number of times and still must protect the contents from spoilage or contamination. It is, yet, important that the container is stably ...

[0006]The present invention relates to a stackable container for items, such as food, comprising a base and lid with secure sealing mechanisms. Each of the base and lid comprises corresponding three rims and three edges being mateable to provide multiple layers of sealing mechanisms to ensure durable sealing. The lid further comprises a sealing lip for locking the lid onto the base and for providing another layer of sealing. Each of the base and lid further comprises partially planar raised portions and further raised portion around the outer perimeter of the planar raised portions for providing stable stacking mechanism. The lid further comprises a tab for easing a user to open the lid without spoilage.

Problems solved by technology

Even though the structure provides adequate sealing mechanism between a container base and lid, the triple sealing mechanism is not durable enough to prevent breakage.

Once the first sealing structure or rim is broke, the item or contents inside the container may easily be contaminated since it only provides two layers.

Further more, sealing structure provides an air pocket or space between the base and lid for easing detaching and opening of the lid; however, this structure works negatively and makes the item inside the container easily be contaminated when the rim is broken.

Another shortcoming of these inventions is the fact that it does not provide proper support for stacking the assembled containers.

There are wider room to slide side way, thus it is not suitable for stacking more than a few or transporting stacks of the containers.

However, not having proper means to assist a user to detach the lid from the base will still cause spoilage.

Even worse, liquid may penetrate into these air gaps of the sealing mechanism defined in between the lid and base by filing it up, and, when it happens, makes it even harder to detach the lid from the base.
