The present invention relates to reconfigurable containers and more particularly this invention relates to alternative utilitarian use of the inner wall of a double wall container. In greater particularity the present invention relates to the class of double wall containers describe generally as tumblers or glasses. More particularly, the present invention relates to a double walled container wherein the inner wall can be separated from the outer wall and reattached in an inverted position, thereby transforming an open topped double wall container into a single wall container with increased size and volume.
Double wall containers consist of an outer and inner wall separated by an air space. This air space often functions as a thermal barrier of varying efficiency depending on the construction methods and materials of the container item. In most cases, the inner wall and outer wall are permanently fixed to each other and cannot be separated. There are a variety of double wall containers on the market including: standard double wall drinkware which is a very common style of drinkware using and inner and outer wall bonded together as exemplified by the OrbitĀ® tumblers sold by the assignee of this application; Leeds Geometric Stainless Sports Bottle in which a stainless steel inner liner is removably attached to an acrylic bottle such that the stainless steel inner liner is removable for easy cleaning or use of the acrylic bottle without the liner; Screw on Insert Drinkware which is regular double wall drinkware but the inner and outer walls screw together so that the end user can insert their own imagery. The top part screws off to slide a photo in; The Hooler which is actually a can holder type drinkware that uses the space between a can and outer wall to fill with ice & water to quickly chill a drink; the Twice Around Tritan Bottle which is a style of drinkware that has a small opening for sipping and a larger opening for inserting ice cubes.
The present product improves and advances the art providing a container with a removable inner wall that can be reoriented in regard to the outer wall. The purpose of the reorientation is threefold:
1. To convert the item from an open top container such as a drinking glass or tumbler to an enclosed container such as a water bottle.
2. To increase/decrease the volumetric capacity of the container to suit various usage needs.
3. To decrease the overall size of the container for more efficient storage and transport.
This reorientation can be freely made from half-size double wall to full-size single wall as often as the user wishes. The conversion is made by removing a locking ring that secures the two walls together. The inner wall is then inverted, placed back on top of the outer wall and secured in the new position with the same locking ring. The single-wall configuration of the design increases the interior volume of the container.
Referring to the drawings which are appended hereto and which form a portion of this disclosure, it may be seen that:
Referring to the drawings for a clearer understanding of the invention it may be understood that the core aspect of this product concerns the separation and inversion of the inner wall to change the form and use of the container and/or provide a secondary use within the same item. The drawings depict the product as a drinkware item that will hold liquids, however, the structure could be applied to a wide array of containers and uses. To that end we believe the product has numerous advantages:
1. Two different usage modes, namely as an open top container or as an, enclosed single wall container;
2. Customer access to the space between the inner and outer wall for cleaning, storage of small items/liquid, or decorative inserts;
3. Reduced size for storage; and,
4. Reduced size for shipping.
Again referring to the drawings, it will be noted in
The outer wall or outer shell 18 serves as the base and lower container portion of the item. It will be noted that the outer shell 18 has a reduced diameter threaded region 19 circumscribing its upwardly opening top. Threaded region 19 releasably engages a peripheral mechanical closure or locking ring 21 which functions to tightly secure the inner and outer shells together in both configurations. This part is required to hold the inner and outer walls together in the appropriate positions. It also is responsible for creating compression of the silicone gaskets to create a water tight seal. Referring to
In its simplest form the invention requires: a detachable inner wall or shell that can be inverted and repositioned on outer wall; an outer wall or shell that can interface in multiple positions with the inner wall; and a mechanical coupler to secure the inner and outer walls together in multiple orientations.
Potential products using the teachings of this disclosure are not restricted to holding liquids only, but may be used with various items that will fit within the interior volume of the container are envisioned. The physical form of the invention could be modified to take on different aesthetic and functional designs in response to different customer needs. The invention is also not restricted by size. The scale could be very small, such as to hold medication or beads, or large such as to hold 64 oz of beer i.e. growler, or even a bathtub.
Products made in accordance with this invention are not required to have an opening with a closure or bottle cap on the inner shell. The inner wall could be enclosed on one end similar to the outer wall. There are useful applications to having both walls enclosed on one end, for example, the storage of a t-shirt or other small promotional items within the closed bottle which can be converted into a tumbler after the promotional item is removed. Likewise products made in accordance with this disclosure are not restricted to material. The disclosed embodiments may be made of acrylic, other plastics or metals and other materials that lend themselves to container utilization. In an embodiment made of stainless steel, it may be possible to create a vacuum sealed version that adds extra thermal protection.
Although the illustrated embodiments disclose the use of sealing gaskets, the products made in accordance with this disclosure are not required to be water tight. The most common use will probably be to have a water tight design, but storage of non-liquid items will not require it. The watertight design may be accomplished as disclosed with the gaskets, or the peripheral sealing flange may be configured to create a labyrinth type seal with the mechanical closure and or the outer shell.
In another embodiment, the locking ring could be eliminated if the inner and outer wall were to have threads molded directly into the parts. This would, in our opinion, make for a less desirable and comfortable lip to drink from when used a drinking tumbler. This might also remove the need for the two silicone gaskets. The method for securing the inner and outer walls could also be redesigned to be more complicated than the current version.
While in the foregoing specification this invention has been described in relation to certain embodiments thereof, and many details have been put forth for the purpose of illustration, it will be apparent to those skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
