MODULAR CASE FOR WATER PIPES AND ACCESSORIES
A modular water pipe case body, bottom and cap subassemblies that are assembled to contain a water pipe and optionally its accessories. The body subassembly includes a sheath that attaches to the bottom and cap subassemblies. The bottom subassembly includes an attachment portion that engages a base of the water pipe to keep it in place inside the water pipe case. The cap subassembly can include a storage compartment. An optional insert may be provided, which is inserted into the body and is configured to retain accessories for the water pipe.
This application claims the benefit of U.S. Provisional Application No. 63/168,796 filed Mar. 31, 2021, the entirety of which is incorporated herein by reference.
TECHNICAL FIELDThe present disclosure relates to protective and carrying cases for smoking utensils, and in particular to cases for water pipes and associated accessories.
TECHNICAL BACKGROUNDWater pipes—smoking devices that incorporate a water filtration system—(bongs, shisha pipes, hookahs, etc.) may be manufactured of a variety of materials, including glass, metal, acrylic, silicone, ceramic, and metal. Water pipes may be used as a manner of personal expression, and therefore may be fanciful in design. Because of their construction, some water pipes may be fragile or more susceptible to damage. This presents a concern when transporting a water pipe. Additionally, water pipes may be used with a number of small accessories, such as downstems and bowls, that are potentially easy to mislay.
Many users employ soft-walled, padded carrying cases to transport their water pipes and associated accessories. Despite their padding, there may be a concern that the water pipe may be damaged if a soft-walled carrying case is crushed. Additionally, many conventional carrying cases are rather utilitarian in shape and appearance. Furthermore, some users may wish to store their water pipe in an open area (e.g., on a shelf), while doing so discreetly.
In drawings which illustrate by way of example only embodiments of the present application,
The examples and embodiments described in this disclosure provide a case for a water pipe that provides both protection from damage and a convenient means of transporting the water pipe together with its accessories and smoking substance (such as tobacco or cannabis). The case includes at least a separable bottom portion and cover (e.g., a sheath), with the water pipe configured to be retained in a fixed position with the bottom portion. This immobilizes the water pipe within the case, reducing the risk of damage during transport. The water pipe and the bottom portion may be configured to be removably connected with each other, for example with a threaded pin and box construction. Additionally, the case can include a removable cap portion. As will be appreciated from the description below, the various portions of the case may be provided as subassemblies of multiple components, which provide additional functionality such as a concealed storage compartment in the cap portion for storing accessories or the smoking substance and the possibility of replacement parts to change the appearance of the case. The case may also comprise an insert for storage of accessories.
An example water pipe case 10 is shown in
The exterior of the case 10 can take any desired shape and appearance and can be formed of any suitable material, including but not limited to metals (e.g., aluminum, stainless steel), fibrous materials (e.g., bamboo, wood veneers), composites, and plastics. The exterior surface may include ornamentation such as texture or graphic patterns. In the example illustrated in the accompanying drawings, the exterior of the case 10 resembles a common vacuum flask for beverages. This ensures that the case 10 can be displayed in a common area in a discreet manner, because it can blend in with similar objects.
As will be seen from the example described below, the case 10 may include several discrete components that may contribute to the ornamental appearance through the selection of distinct materials or ornamentation. In some embodiments, some of these components may be combined in single units that integrate the functionality of the discrete components, or eliminated altogether. For example, in the example depicted in the drawings, the body subassembly 200 includes upper and lower rings 230, 240 which provide optional ornamentation and provide attachment points for an optional handle 240. However, one or both rings 230, 240 and even the handle 248 may be omitted. If the handle 248 is provided, it may be attached directly to the case 10 without the use of the rungs 230, 240.
As can be best seen in the cross-sectional view of
The specific exterior and interior shape of the inner and outer cap components 120, 110 may be varied. For example, while these examples have a rounded dome top 112, 122, the top can be squared-off or some other symmetric or asymmetric shape.
An interior lid component 130 is illustrated in
It will be appreciated by those skilled in the art that other means for attaching the interior lid component 130 to the inner cap component 120 may be used. For example, the interior lid component may not be threaded at all, but instead press fit into a mating section of the inner cap component 120 (e.g., with a rubber O-ring seal), or hinged. An elastomeric seal may be disposed between the inner cap component 120 and interior lid component 130 to ensure that the compartment is substantially or completely water- or air impermeable, to avoid contamination of the compartment contents and minimize scent leakage.
In a simple embodiment, not shown, the cap subassembly 100 may simply comprise a single cap piece without an inner compartment—for example, a single cap component provided with a single interior threaded portion for mating with the body subassembly 200. Alternatively, the cap subassembly 100 may still include a compartment formed in cooperation with an interior lid component 130, but with the functionality of the inner and outer cap component combined into a single, integral unit. However, the use of distinct inner and outer cap components 120, 110 enables the use of more decorative materials for the outer cap (e.g., metals such as aluminum or stainless steel, or other materials such as bamboo), while a more durable but less attractive material may be used for the inner cap component 120 and interior lid component 130 (e.g., a food grade plastic).
Components of an example body subassembly 200 are shown in
The sheath 210 is sized with an interior diameter that is sufficient to accommodate the water pipe with sufficient clearance to allow the water pipe to be removed. In this example the sheath 210 is substantially cylindrical and extends between an upper opening edge 222 and a lower opening edge 224. The upper portion of the sheath 210 comprises an upper, smaller diameter sidewall 226 bearing a threaded portion 227 on its exterior surface. The upper sidewall 226 transitions at a shoulder 228 to a sidewall 220 of larger diameter, which comprises a principal portion of the sheath 210. As will be understood from the discussion of the cap subassembly 100, the threaded portion 227 of the sheath 210 provides an attachment portion that engages with the threaded section 128 of the cap subassembly 100. The reduced diameter of the upper sidewall 226 ensures a smooth transition on the exterior surface of the water pipe case 10 when the cap and body subassemblies 100, 200 are joined. Those skilled in the art will appreciate that the cap and body subassemblies 100, 200 may have different dimensions while still fulfilling the functions described herein.
In this example, the body subassembly 200 includes an optional handle 248, which is mounted on the sheath 210 by means of upper and lower rings 230, 240 which encircle the sheath 210 at or near its upper and lower ends, respectively. The upper and lower rings 230, 240 in this example are dimensioned to provide an interference fit with the sheath 210; however, in some implementations the rings 230, 240 may be adhered to, or moulded on, the sheath 210.
The upper ring 230, having a smooth interior surface 232, may be located at any appropriate position on the sheath 210. The interior surface 242 of the lower ring 240, on the other hand, includes a threaded portion 243 which provides an attachment portion that engages the bottom subassembly 300 of the water pipe case 10. Thus, the lower ring 240 is mounted at the lower opening edge 224 of the sheath 210 so that the threaded portion 243 projects beyond the lower opening edge 224.
Each of the upper and lower rings 230, 240 includes a connector portion 236, 246, to which the optional handle 248 may be mounted, for example using links (not shown). The exterior surfaces 234, 244, as can be seen in
As the handle 248 and the rings 230, 240 are optional, in some implementations the body subassembly 200 may consist of a single piece, the sheath 210, provided with integrated attachment portions for engaging the cap subassembly 100 and bottom subassembly 300. Thus, for example, the interior surface of the sheath 210 may include a threaded portion at its lower end for engaging the bottom subassembly 300, such that a separate ring 240 is not required.
An example bottom subassembly 300 is illustrated in
The base 312 is contoured as necessary to fit the water pipe 20 and includes an attachment portion for removably attaching the water pipe. The attachment portion in this example is a central interior depending sidewall 315 with a threaded portion 316 that cooperates with a corresponding threaded portion of the water pipe. The interior sidewall 315 terminates in a floor 318, best seen in the cross-sectional view of
In an alternative implementation, the exterior bottom component 320 may provide the attachment means to connect the body subassembly 200 and the bottom subassembly 300. For example, the exterior bottom component 320 may include an exterior threaded portion that can mate with the body subassembly 200, while the interior bottom component 310 attaches to the water pipe 20 and fits within the exterior bottom component 320. In yet another implementation, the bottom subassembly 300 may consist only of a single component that attaches to both the water pipe 20 and the body subassembly 200; for example, the bottom subassembly 300 may comprise only the interior bottom component 310, although the interior bottom component 310 in this case will be externally visible when the water pipe case 10 is assembled. In any of these implementations, the single-piece or multiple-piece bottom subassembly 300 retains the water pipe 20 in fixed relation to the body subassembly 200, because the bottom subassembly 300 is attached to the water pipe 20.
To assemble the water pipe case 10 with the water pipe 20, the water pipe 20 is screwed into place on the interior bottom component 310, with the threaded portion 26 of the water pipe 20 engaging the threaded portion 316 on the interior sidewall 315 of the interior bottom component 310. The shaped bottom portion 24 of the water pipe 20 (indicated in
Optionally, if the cap subassembly 100 is configured with a storage compartment, before attaching the cap subassembly 100 to the body subassembly 200, the material for storage may be placed in the interior cap component, then the storage compartment closed off with the interior lid component 130.
It will be understood that the assembly of the water pipe case 10 with the water pipe 20 may take place in a different order, for example with the cap subassembly 100 being attached to the body subassembly 200 before the bottom subassembly 300 is attached the body subassembly 200, or with the exterior bottom component 320 being applied last. In some implementations, the separate exterior bottom component 320 may be eliminated altogether. Since the water pipe 20 is anchored within the water pipe case 10 by its connection to the bottom subassembly 300, movement of the water pipe 20 within the case 10 is minimized and the pipe 10 is unlikely to contact the interior of the sheath 210 during transport.
The water pipe case 10 may be disassembled by disconnecting the cap subassembly 100 and the bottom subassembly 300 from the body subassembly 200 and removing the body subassembly 200 to expose the water pipe 20. The water pipe 20 may then be used. It is not necessary to remove the water pipe 20 from the bottom subassembly 300, as the bottom subassembly 300 provides a stable base for resting the water pipe 20 on a surface.
It will be appreciated from the foregoing that other means for removably attaching the cap subassembly 100, body subassembly 200, bottom subassembly 300, and water pipe 20 may be used. Screw connections such as those described herein are particularly suitable because they provide an attachment that is secure with normal use, while providing for easy disassembly. Snap-fit connections may be used instead; for example, the base 25 of the water pipe may be pressed into the bottom subassembly, and/or the bottom subassembly may be snap-fit to the body subassembly, and/or the body subassembly snap-fit to the cap. The use of the threaded pin and box connection between the water pipe 20 and the bottom subassembly 300 may be more beneficial for some water pipe designs, because the use of a snap-fit connection may be more likely to lead the user to apply force on the smoke chamber portion of the water pipe 20 when attempting to separate the water pipe and the bottom subassembly 300, which bears an increased risk of damage to the water pipe.
In another implementation, the water pipe 20 may be integrated with the bottom subassembly 300 as a unitary element. In such an implementation, the body subassembly 200 could be screwed directly onto the water pipe 20. In that case, the base of the water pipe 20 may have a greater exterior diameter and a threaded portion provided on the exterior diameter the base, which can mate with the lower threaded portion of the body subassembly 200.
Furthermore, while the example depicted in the accompanying drawings is a beaker design, other types of water pipes can be similarly adapted for a similar threaded connection with the bottom subassembly 300. For example, a straight tube water pipe generally consists of a narrow cylindrical pipe of constant diameter with a projecting neck. Conventionally, the bottom of the straight tube is connected to a flat base of greater diameter for stability. In one implementation, the bottom of the straight tube may not be enlarged but may instead be provided with a threaded portion that can be mated with a threaded portion of the bottom subassembly. Since the design of the case 10 is modular, different bottom subassemblies 300 configured to engage different water pipe designs may be provided for the same body subassembly 200. Thus, the user has the option of changing parts to fit a particular water pipe.
Alternatively, the enlarged base of a water pipe (whether a straight tube, beaker, or other design) may be configured to attach to the body subassembly 200 directly, without the use of a separate body subassembly 300.
As mentioned above, exterior components of the water pipe case 10 may be formed of suitable materials. In the example illustrated in the accompanying drawings, the outer cap component 110, sheath 210, and exterior bottom component 320 may be formed in a material selected for its decorative and/or protective value (e.g., metals, aramid or carbon-fiber composites, bamboo or wood), while those components directly contacting the water pipe case 10 and/or contents of the storage compartment in the cap subassembly 100 may be selected for other qualities (e.g., food-safe or water-resistant materials).
An insert may be provided for additional protection and/or storage of accessories. An example insert 50, which may be manufactured of a foam material (e.g., ethylene-vinyl acetate foam) is shown in
If the insert 50 is also used for storage, its upper portion 55 may be substantially solid with apertures or recesses (collectively, “cut-outs”) cut into the upper surface for receiving various accessories. Examples of such cut-outs 60a-60h are shown in
Cut-outs may be formed by moulding or casting expanding foam in the desired shape for the insert, or alternatively carving a solid piece of insert material. The term “cut-out” is not intended to be limiting to a particular method of manufacture.
Throughout the specification, terms such as “may” and “can” are used interchangeably. Use of any particular term should not be construed as limiting the scope or requiring experimentation to implement the claimed subject matter or embodiments described herein. Exemplary embodiments of the invention having been discussed, it will be understood that the invention described herein encompasses all variations and modifications as would be apparent to those skilled in the art. Options or variations described in connection with one embodiment may be combined with other options or variations of other embodiments. While this disclosure may have articulated specific technical problems that are addressed by the invention(s), the disclosure is not intended to be limiting in this regard; the person of ordinary skill in the art will readily recognize other technical problems addressed by the invention(s).
