Description
Background of the Invention
1. Field of the Invention
This invention pertains generally to food holders and, more particularly, to a lunch holder for carrying a plurality of food products.
2. Description of Related Art
Heretofore, a number of different types of carriers or containers have been utilized in packing and carrying lunches. These have included disposable carriers such as paper and plastic bags, cardboard boxes and the like, and more permanent carriers such as boxes fabricated of metal and/or plastic. With such carriers, a variety of containers have been utilized for holding different food products, such as sandwiches, potato chips, pickles, fruit, cookies and the like.
Objects and Summary of the Invention
It is in general an object of the invention to provide a new and improved food holder which is particularly suitable for holding and carrying the types of food products which typically make up a lunch.
Another object of the invention is to provide a food holder of the above character which is light in weight and economical to manufacture.
These and other objects are achieved in accordance with the invention by providing a lunch holder having first and second sections which are hingedly connected together along one side thereof in clamshell fashion, a divider which separates one of the sections into a plurality of compartments for holding different food products, and a lid which is hingedly connected to the one section along a second side thereof for movement between covering and uncovering positions relative to the compartments. In one presently preferred embodiment, the two container sections, the divider and the lid are fabricated as a unitary structure of a semi-rigid plastic material.

Detailed Description
As illustrated in the drawings, the lunch holder has a base section 11 and a cover section 12 which are connected together along one side thereof in clamshell fashion by a hinge 13 for movement between an open position in which the two sections are positioned side-by-side as illustrated in FIG. 1 and a closed position in which the two sections are superposed with the cover section positioned above the base section as illustrated in FIG. 2.
The base section has a rectangular bottom wall 14 and side walls 16-19 which taper outwardly from the bottom wall by an angle on the order of 15 degrees. The top section has a wall 21 similar to bottom wall 14 and side walls 22-25 similar to walls 16-19. Even though wall 21 is actually on top when the cover section is inverted above the base section in the closed position, this wall is conveniently referred to as the bottom wall of the cover section since it is on the bottom when the cover section is in the open position.
The base section is divided into a plurality of compartments for holding different food products by a T-shaped partition 27 consisting of a relatively long panel 28 which extends between opposite side wall 16, 18, and a relatively short panel 29 which extends between the intermediate side wall 17 and the longer panel. The panels extend from bottom wall 14 to a height approximately even with the tops of side walls 16-19 and form one compartment 31 between the longer panel and side wall 19, and two additional compartments 32, 33 on opposite sides of the shorter panel.
A lid 36 is hingedly connected to the base section along the upper margin of side wall 17 for movement between covering (closed) and uncovering (open) positions relative to compartments 31-33. A seal 37 is provided on the lower side of the lid for engagement with the upper edge portions of the T-shaped partition when the lid is in the covering or closed position. This seal comprises spaced apart flanges 38 which define channels 39 in which the upper edge portions of the partition are received.
The lid seats against a shoulder or ledge 41 which projects horizontally in an outward direction from the upper margins of side walls 16-19, with an upstanding peripheral flange 42 along the outer edge of the shoulder in sealing engagement with the periphery of the lid when the lid is closed. Frictional engagement between the flange and lid holds the lid in the closed position, and a tab 43 projects laterally from the lid through a gap 44 in the peripheral flange on side wall 19 to facilitate lifting of the lid.
In the embodiment illustrated, cover section 12 has a single compartment 46 for holding larger food products such as a sandwich, and there is no lid for this compartment other than lid 36 in the base section. If desired, however, the cover section can be formed into a plurality of compartments and provided with a lid of its own. Similarly, the base section can be divided into any desired number of compartments with suitable partitions.
The cover section has a shoulder 48 which projects laterally from side walls 22-24 and abuts against the upper surface of flange 42 on the base section, and a peripheral skirt or flange 49 which extends from the outer margin of the shoulder and fits over the flange on the base section to seal the compartment in the cover section. The cover section is retained in its closed position by a catch 51 which extends from side wall 24 and engages a lug 52 on side wall 18. Tabs 53 project from side wall 18 on opposite sides of the lug and facilitate disengagement of the catch.
In one presently preferred embodiment, the entire lunch holder is fabricated as a unitary structure of a semi-rigid plastic material such a polypropylene by a suitable molding process.
In operation and use, cover section 12 and lid 36 are swung to their open positions, and food products such as potato chips, pickles and cookies are placed in compartments 31-33. Lid 36 is closed, sealing these compartments, and another food product such as a sandwich is placed on top of the lid. The cover section is then closed, sealing the sandwich in compartment 49, and catch 51 is engaged with lug 52 to hold the cover section in the closed position.
To open the container, the catch is disengaged from the lug, the cover section is swung to the side of the base section, the sandwich is removed, and the lid is opened to provide access to the food products in the base section. The catch is disengaged from the lug relatively easily by placing the thumb on top of one of the tabs 53, placing the forefinger beneath the catch, and lifting the catch away from the lug with the finger while the thumb bears down on the tab.
The lunch holder has a number of important features and advantages. It is light in weight, economical to manufacture, and easy to use. It is easily cleaned and can be used repeatedly to hold a variety of food products.
It is apparent from the foregoing that a new and improved lunch holder has been provided. While only certain presently preferred embodiments have been described in detail, as will be apparent to those familiar with the art, certain changes and modifications can be made without departing from the scope of the invention as defined by the following claims.
