TECHNICAL FIELD

The present invention relates to a reusable drinking container or liquid carrying container and more specifically, to a container that utilizes a glass interior container for a non-toxic and environmentally friendly reusable container and a bamboo, wood, carbon-fiber or other renewable and re-usable outer covering.

BACKGROUND

Plastic drinking bottles have increased rapidly in popularity in the past 20 years. The disposable containers have been used to contain water, juices, sodas and other beverages. Recently there has been an emergence in reusable drinking containers as a result of both environmental concerns and health concerns. As plastic water bottles have become increasingly used, the amount of waste that has accumulated and the amount of petroleum used in the production of the bottles has become an environmental concern. Additionally, the overabundance of plastic bottles that end up in land fills has become a further environmental concern. Health concerns have also been raised around the used of Bisphenol A (BPA), which has been used in making polycarbonate plastic drink containers. Although there has been significant controversy over the safety of BPA, it has been linked to developmental, neural and reproductive problems when ingested.

As a result of the environmental and health concerns posed by plastic drinking containers many consumer have begun using reusable drinking containers. Initially the majority of these reusable containers were plastic based products. As a result, the concern over BPA was not diminished by the use of reusable plastic bottles. BPA is an ingredient in the manufacturing process of hard, clear polycarbonate plastics and chemicals from the containers can leach from the plastic particularly when the containers are heated, cleaned with harsh detergent or exposed to an acidic substance.

In an effort to overcome the health concerns caused by plastics, stainless steel or aluminum water bottles were introduced as a replacement option for a reusable drinking container. These stainless steel reusable containers are now becomingly increasingly scrutinized for both health and environmental reasons. First, manufacturing the stainless steel bottles requires large amounts of energy, much higher amounts than are required for other drinking containers. Additionally, many manufacturers of the stainless steel reusable containers line the interior of the bottle with a synthetic coating that contains BPA or another potentially harmful substance, such as BADGE. BADGE has been shown to genetically modify cells and cause cancer in lab testing. The possibility of aluminum contamination has been associated with various health risks, including Alzheimer's disease, arteriosclerosis and other possible neurological side effects. Due to the increasing concern surrounding stainless steel reusable containers there is a need for an environmentally friendly and safe reusable container.

Accordingly, what is needed is a reusable drinking container that includes an inner container that holds the potable liquid and is made from a material that is non-toxic and does not pose environmental and health concerns, such as glass, as well as an exterior container into which the interior container fits that is able to be manufactured in an environmentally friendly way that incorporates safe materials that are renewable and sustainable and that can be recycled, such as bamboo, wood, carbon-fiber and the like.

DESCRIPTION OF THE INVENTION

The present invention features a drinking or liquid carrying container 10, FIG. 1, that includes a safe, non-toxic inner portion 12 that contains any potable liquid made of glass, and a renewable protective outer portion 14 made of bamboo, wood, carbon-fiber or the like. It has been shown that the only water bottles that are 100% safe to use are those that are made from glass. Traditionally, glass has been thought of as a material that is breakable and rather heavy. Glass is, however, extremely safe. Glass has not been shown to be toxic or to leach chemicals or negative flavors into a contained liquid. Additionally, glass is entirely recyclable.

In a preferred embodiment of the present invention, the drinking apparatus includes a glass inner portion 12 that replaces traditional synthetic and toxic liners. The glass that will preferably be used for the inner portion 12 will be microwave and dishwasher safe. The glass will be fortified such that a drop should not break the glass. The glass can be any type of glass product, however the glass will preferably be shatter-proof or break-proof. Such glass is well known in the art.

The inner portion 12 includes an upper opening 28 and may also optionally include a lower opening 26. The upper opening 28 will preferably be wide enough that the opening can easily accommodate ice cubes. The inner portion 12 is provided with an upper threaded attachment region 22 as well as a lower threaded attachment portion 24.

The drinking apparatus 10 also includes an outer portion 14 that is preferably made from a renewable and/or recycled material such as bamboo, wood (such as oak from used wine barrels), carbon-fiber material and the like. The outer material such as bamboo provides a sustainable, renewable and environmentally friendly material that provides protection to the inner portion 12 and also is easy to grip by a user and provides some insulative value, preventing the user's hand from coming in direct contact with a hot or cold inner portion 12. Bamboo is a preferred material as it may be harvested using a sustainable, selective cutting method. The outer portion 14 may be manufactured by molding and/or gluing or otherwise fusing thin strips of individual bamboo or wood pieces together. This process would increase the strength of the outer portion 14 and reduce waste in the manufacturing process and allow for the use of small pieces of material that might have been unused from other manufacturing processes.

The outer diameter of the outer portion 14 will preferably be designed to fit easily into a car's cup holder. Preferably, the inner portion 12 is removable from the outer portion 14, such that the inner portion 12 can be effectively and easily washed by hand or in a dishwasher.

The inner portion 12 can be slid into the outer portion 14 and effectively held in place by a bottom member 16, such as a screw on cap, screw on ring or other similar attachment means. The bottom member 16 can be plastic, rubber or any other suitable material and will preferably be recyclable. The bottom member 16 will preferably entirely cover the lower opening 26 of the inner portion and provide an effective non-leaking seal. In this embodiment, the inner portion 12 includes a lower region 15 near lower opening 26 that tapers inward and has a diameter that is less than the diameter of the remainder of the inner portion 12. The lower region 15 forms a “step” which when the inner portion 12 is installed in place in the outer member 14 abuts onto outer member ridge portion 17. When bottom member 16 is screwed onto lower threaded region 24 of the inner portion 12, the inner portion 12 is pulled down tightly against the ridge portion 17 holding the inner portion generally snugly in place within the outer portion 14.

Alternatively, in another embodiment of the invention, the drinking apparatus 10 may not require a bottom member 16 as the inner portion 12 may not have a lower opening 26. In this embodiment, the outer portion 14 would wrap entirely around the bottom of the inner portion 12. In another embodiment, the inner portion 12 may include a wider lower region of approximately the same size as lower member 16. In this embodiment, the inner portion 12 may be inserted into the cavity of the outer member 14 upward from the bottom region of the outer member 14 with the bottom of the inner member 12 resting against the outer member 14.

The bottom member 16 preferably includes a top side 46, FIG. 4, and a bottom side 48. The top side 46 of the bottom member 16 includes one or more protrusions or tabs 30 located on an upper rim portion 36 of the bottom member 16. The one or more protrusions 30 are configured to fit into one or more slots 32 (FIG. 2) located within a lower surface or region 34 of the outer portion 14. In a preferred embodiment, two protrusions 30 are provided on the bottom member 16, wherein a first protrusion 30a is placed 180 degrees opposite a second protrusion 30b, as seen in FIG. 4. In this preferred embodiment, the lower surface 34 of the outer portion 14 would feature two slots 32 configured to receive the two protrusions 30. The protrusions 30 fit into the slots 32 of the outer member 14 thereby ensuring the outer member 14 cannot rotate in relation to the bottom member 16 when the cap 20 is twisted on or removed from the bottle 12.

The bottom member 16 may further include ridges 38, FIG. 4. The ridges 38 are located on an inner surface 40 of the bottom member 16. The ridges 38 are configured to make contact with the inner portion 12 at the lower threaded attachment 24. The ridges 38 interlock with a plurality of ridges or other protrusions on a bottom edge 42 of the lower threaded attachment 24, thereby locking the bottom member 16 to the inner portion 12 such that the combination of the bottom member 16 and inner portion 12 will not come unscrewed or detached when rotating (removing or replacing) an attachment member 18 or top member 20 (as described above and below).

Additionally, the bottom member 16 may feature one or more holes or openings 44. The one or more holes or openings 44 are designed to allow moisture from condensation or spillage to flow out of the drinking apparatus 10. The one or more holes 44 prevent moisture from becoming trapped in the bottom member 16.

An attachment member 18 is attachable to the upper threaded attachment 22 of the inner portion 12. The attachment member 18 is a ring like device that attaches and thereby secures the inner portion 12 in place to the outer portion 14. The attachment means for the attachment member 18 preferably includes a threaded attachment that is compatible with the upper threaded attachment 22 of the inner portion 12. The attachment member 18 is preferably a large ring like nut and may be plastic, rubber or any other suitable material.

Additionally, a top member 20 in the form of a cap is then securable to the upper threaded attachment 22 of the inner portion 12. The top member 20 comes in direct contact with the attachment member 18. The top member 20 serves as a leak-proof cap, which fully covers the upper opening 28 and provides a leak-proof seal. The top member 20 may be plastic, rubber or any other suitable material and will preferably be recyclable. The top member 20 may be in the shape of a flat cap as shown in FIGS. 2 and 3 or alternatively, may include a loop, ring or other karabiner-style design (shown generally as 50 in FIG. 1) in order to allow a user to attach the drinking apparatus 10 to a bag or to hold the drinking apparatus 10 more easily with one or two fingers.

In another embodiment of the present invention, the attachment member 18 may not be used and rather the top member 20 would serve as both the cap and the attachment means, securing the inner portion 12 to the outer portion 14 and also providing a cover over the upper opening 28. The top member 20 may also feature other various accessories, such as a straw (not shown) that is designed to pull fluid from the bottom of the inner portion 12.

Accordingly, the present invention provides a novel drinking apparatus using a combination of bamboo and glass that improves upon all existing reusable drinking containers. The outer portion 14 serves to protect the inner portion of 12 and also provides insulating qualities. The drinking apparatus preferably includes an inner portion 12 and recyclable bottom member 16 and top member 20, which creates a drinking apparatus that is easy to use and assemble, easy to drink from, and easy to clean.
