Description

MULTIPURPOSE TOTE LUNCH BAG PRIORITY CLAIM

This application claims priority to the filing date of U.S. Provisional Patent Application Serial No: 60/238,859 filed on October 7, 2000.

BACKGROUND OF THE INVENTION Field of Invention

The present invention relates to the field of portable food containers for carrying or transporting food and beverages which are convenient to use and protect the contents therein.

Description of Prior Art

In a fast moving society, the need to have portable containers to carry food and the like is growing in importance. Given today's push towards healthier foods, the need to transport particular and personally prepared foods is on the rise. While portable containers for carrying food items have been known for many years in the prior art, such inventions do not address all of the problems associated with transporting perishables. Many lunch bags found in the prior art suffer from being either too small, and therefore limited in the amount of perishables that can be carried, or too bulky and large, thereby making transportation more cumbersome and less desirable. Another problem not addressed in the prior art is the need for a lunch bag which protects and keeps perishables in place, while at the same time providing easy accessability to the items contained therein. This is particularly useful when the user is in transit or in a hurry. Two other desirable attributes include the ability to keep perishables either warm or cool. Finally, the ability to convert a lunch bag for other uses is also desirable. The prior art addresses some of the above concerns, but not all. For example, in Campbell, U.S. Patent No. 4,211,091 a transportable lunch bag is described. However, while this reference addresses the issue of compactness, nothing is claimed with respect to accessability and the securing of food items. In addition, this reference makes no provision for a lunch bag to be converted for other uses. This reference is also relatively small, and therefore limited in the amount of perishables that can be carried.

In Christman, U.S. Patent No. 5,813,445, a bingo tote bag is described. While this reference addresses the issue of caπying a beverage container and providing accessability to bingo items, it makes no claim with respect to a food container or the securing or insulation of items therein. Although this reference indicates that a bingo player may place snacks inside the tote bag, no provision is made for carrying or transporting perishable items.

LikewiseJn Giampapa, U.S. Patent No.6,059,179, whichrelates to amulti-use container that can be used for shipping, as a picnic basket, or configured into a mat for eating upon, addresses some issues regarding portability and accessibility. Giampapa, however, fails to address the problems of securing food and beverage items during transportation. In addition, it makes no claims to insulating items. Moreover, Giampapa comprises a container designed to be converted for shipping making it too bulky and large, for convenient, less cumbersome day- to-day transportation.

In view of the foregoing, there is a need for an apparatus that overcomes the deficiencies in the prior art.

SUMMARY OF THE INVENTION

The present invention allows for a multi-use tote lunch bag which addresses the object of easy accessability, securing food items, keeping food items either warm or cool, protecting items, compactness, and the ability to convert the tote lunch bag for other uses. The tote lunch bag provides for a tote bag comprising a means for opening and closing thereof and a carrying means affixed to the tote bag. The tote bag further comprises a means for securing and transporting an insulated lunch case and liquid carrying container, as well as compartments that may be used for securing and transporting eating utensils and accessories, condiments, papers or work-related supplies, wallets, keys or other personal belongings.

The insulated lunch case comprises a means for storing, securing, and transporting food items and protecting perishables. In a preferred embodiment of the present invention, the lunch case would comprise four walls, with each wall consisting of an outer wall and an inner wall with a layer of an insulating material placed there between. The insulated liquid caπying container comprises a means for storing, securing, and transporting liquid items and protecting perishables. In a prefeπed embodiment of the present invention, the liquid carrying container would typically form a cylindrical shape, and include a means for insulating the liquid contents, such as an outer wall and inner wall with the inner wall comprising an insular material. A primary objective of the present invention is to provide a multi-use tote lunch bag having advantages not taught by the prior art.

Another objective is to provide such a tote lunch bag that conveniently and securely transports perishable items, eating utensils, accessories, as well as personal items, while making the items easily accessible. A further objective is to provide such a tote lunch bag that is convertible for other uses such as a means of transporting personal belongings.
