Description
- 1. Field of the Invention
- The present invention relates to a flask for holding liquids and, more particularly, to a flask that is expandable so that the capacity of the flask may be adjusted (i.e., either increased or decreased) by a user.
- 2. Description of the Related Art
- Flasks are convenient accessories for carrying beverages and spirits on a person. Generally speaking, there are two types of flasks: a hand-carried flask and a breast-pocket flask type. Hand-carried flasks are more commonly known by the registered trademark of the most successful brand thereof, Thermos®, and include an evacuated cylinder disposed within a protective housing with a handle. The capacity of such flasks typically range from a pint to a quart and are designed to carry hot beverages such as coffee or soup.
- Breast-pocket flasks were traditionally designed to be carried not in-hand typically but in the breast pocket of a blazer or sport coat. This tradition has carried through to today with the flasks often being arcuate to complement the shape of the human anatomy adjacent to the area where the breast pocket of a coat is located when worn. These types of flasks are typically not designed to carry hot beverages but, rather, a quantity of spirits such as brandy or bourbon. Typical sizes are fixed and range from one-half pint to one pint in size.
- One of the drawbacks of conventional flasks is that, for flexibility, a user needs to purchase several depending upon need. If the user is to carry a quantity of spirits for individual use, then a smaller flask may be used. However, if the user is to carry a quantity of spirits for a group of people, then a larger flask may be used.
- In view of the foregoing, there remains a need in the art for flasks that may have capacity adjusted according to need.
- The present invention provides flasks that are capable of having their capacity adjusted—either increased or decreased—by a user. According to a preferred embodiment, a flask includes a cover element and a container. The cover element has an opening through which liquid is passable and a mating edge. The container has a mating edge for engaging with the mating edge of the cover element to form a seal. A fastener is provided and configured to secure the cover element and the container together with the mating edges engaged, thereby defining a reservoir therein. The fastener may include, for example, one or more bolts.
- The container may include a base element with a mating edge and one or more expansion elements each having a top mating edge for engaging with the mating edge of the cover element and a bottom mating edge for engaging with the mating edge of the base element. Accordingly, a user may add and remove expansion elements to the flask to adjust the capacity thereof. For example, for a larger capacity, three of the expansion elements may be positioned between the cover element and the base element; for a smaller capacity, only one (or none) of the expansion elements may be provided.
- Other objects, features, and advantages of the present invention will become apparent to those skilled in the art from a consideration of the following detailed description taken in conjunction with the accompanying drawings.
