Description

Title

Soft Tip for an Electronic Cigarette

[0001] This application claims priority to U.S. Provisional Application No. 61/768,240, filed February 22, 2013, the contents of which are incorporated herein by reference in their entirety.

Background of the Invention

[0002] The present invention relates to soft tips for electronic cigarettes. More specifically, to a mouthpieces that emulate the look and feel of a traditional cigarette filter without actually filtering the vapor flavoring or the nicotine vapor solution.

[0003] Current electronic cigarettes and other electronic smoking devices lack many of the aesthetic features common to traditional cigarettes, and to which many smokers are accustomed. Electronic cigarettes also function much differently than traditional cigarettes, having an electronic atomizer rather than relying on combustion. Traditional cigarettes typically employ a sponge-like filter to prevent ash and other combustion by-products from being inhaled by a smoker, while electronic cigarettes do not have such by-products and typically employ a hard plastic or metal tube as a mouthpiece without a filter. These electronic cigarettes do not have the same tactile feel as traditional cigarettes and, as a result, many smokers who are accustomed to the feel of traditional cigarettes have been hesitant to adopt them. It is also not ideal to place an actual filter on the end of an electronic cigarette because it may disrupt operation and impede the flow of vapor to the smoker's mouth.

[0004] One of the significant problems presented in making an electronic cigarette feel like a traditional cigarette is that the internal circuitry, sensors and atomizer assembly for an electronic cigarette are not crushable. Additionally, electronic cigarettes have a nicotine liquid or gel that must be kept from leaking. The simplest way to resolve these two issues is to use a sealed, hard shell for the electronic cigarette, sacrificing tactile feel of the electronic cigarette for functionality.

[0005] Several prior art electronic cigarettes have attempted to introduce features to make electronic cigarettes feel to a smoker more like a traditional cigarette. For example, in U.S. Pub. No. 2012/0312313, the inventor describes adhering a padded moisture barrier around the hard shell of an electronic cigarette. This solution provides a padded feel to an electronic cigarette, but does not allow a person to crush or chew the tip without damaging the components in the electronic cigarette.

[0006] Another approach, shown in U.S. Pub. No. 2011/0232654, is to create a removable tip that can be attached to the body of an electronic cigarette, the tip containing a liquid storage chamber wrapped in a sponge-like material. This approach does not resolve the issue of providing a crushable/chewable tip and may increase the potential for leakage because the person would be chewing directly on the liquid storage container.

[0007] Another approach, shown in U.S. Pub. No. 2013/0061861, is to place a padded material at the tip of the electronic cigarette in the location where a person's teeth would naturally close around the electronic cigarette. Inside the padded material is a deformable component that flattens when a person's teeth close on it and open when the person's teeth release it. When the deformable component is not being clamped by a person's teeth, the deformable component is open and allows a vapor outlet to remain open into the electronic cigarette. While this device allows a person to crush or chew the tip, the padded material is in direct contact with the vapor, which would saturate the padded material after repeated use and may increase the chance for leakage. Additionally, the device is complicated and may be prone to malfunction.

[0008] An earlier approach, as shown in U.S. Pub. No. 2006/0254604 simply place a crushable filter on the end of a simulated cigarette. As mentioned above, this approach is not ideal because it places an actual filter in the path of the vapor exiting the electronic cigarette.

[0009] What is needed is a soft tip for an electronic cigarette, which is crushable, feels like a filter but is separated from the liquid storage area to prevent leakage, and does not allow the soft padded tip material to contact or absorb any of the liquid vapor exiting the electronic cigarette. Summary of Invention

[0010] The device is a soft mouthpiece for an electronic cigarette, having the tactile feel of a filter similar to a traditional cigarette without actually filtering or obstructing the aerosol created by the atomizer in the electronic cigarette. The device is a soft tip extending from an end of an electronic cigarette shell, the soft tip having a small impermeable vapor passage tube through it, the vapor passage tube being sealed with the body or shell of the electronic cigarette, the vapor passage tube being wrapped in sponge-like material and the sponge-like material being covered with paper or a sticker.

Detailed Description of the Invention

[0019] As shown in Figure 1, the device comprises a soft tip 1 for an electronic cigarette that feels like a traditional cigarette filter in a person's mouth, which electronic cigarette, as shown in Figure 4, has an atomizer 5 and a shell 4, the atomizer 5 being inside the shell 4. As shown in Figure 1, the shell 4 has two ends, a proximal end 4A near the person's mouth and a distal end 4B away from the person's mouth. The device further comprises a seal cap or a gasket ("seal" 2) which fits in and closes the proximal end 4 A of the shell 4. As shown in Figures 2 and 3, the soft tip 1 further comprises a vapor passage tube 11, also having a proximal end 11A and a distal end 11B. The seal 2 has a hole or valve 2A in it, which receives and encircles the distal end 11B of the vapor passage tube 11. As shown in Figure 4, the distal end 11B of vapor passage tube 11 connects to the atomizer 5 located inside the shell 4. The atomizer 5 is functionally connected to a battery 7 and to a reservoir 55 or supply area for nicotine solution. The atomizer 5 vaporizes the nicotine solution as it passes from the reservoir 55. In one embodiment, as shown in Figures 5A and 5B, the atomizer 5 is aligned with the vapor passage tube 11. The vapor passage tube 11 extends through the hole 2 A in the seal 2 outward from the proximal end 4 A of the shell 4. In one embodiment, the vapor passage tube 11 extends between half an inch and three quarters of an inch from the proximal end 4 A of the shell 4. As shown in Figures 6 and 7, the vapor passage tube 11 and seal 2 may be manufactured as two separate pieces, a single piece, or in the shape of a nipple. In one embodiment, the vapor passage tube 11 is impermeable to liquid, air, vapor and aerosol. In one embodiment, the vapor passage tube 11 is incollapsible. In one embodiment, the vapor passage tube 11 is wrapped in a cotton batting, polyester fiber (e.g. EV Polyester fiber) or some other sponge-like or spongy material ("sponge-like material") 3. During operation, vapor travels from the atomizer 5 through the vapor passage tube 11. The vapor passage tube 11 does not need to be in the center of the sponge-like material 3. The sponge-like material 3 may be glued or adhered to the vapor passage tube 11 to hold the sponge-like material 3 in place. The entire assembled electronic cigarette (shell 4 and soft mouthpiece) is wrapped in paper, a sticker, plastic or some other outer covering 6 creating a soft mouthpiece for the electronic cigarette extending from the proximal end 4A of the shell 4 that simulates the feel of a traditional cigarette filter and simulates the overall feel/aesthetic of a traditional cigarette. The soft tip 1 may also be wrapped separately from the shell 4 of the electronic cigarette. Alternatively, the soft tip 1 device may be used with other smoking devices other than an electronic cigarette, such as an inhaler or a pipe.

[0020] During operation of the electronic cigarette, when a person sucks on the soft tip 1, the aerosol passes from the reservoir 55 to the electronic cigarette's atomizer 5 to the person through the vapor passage tube 11. The vapor passage tube 11 protrudes from electronic cigarette through a seal 2, the seal having a hole 2A, and being located on the proximal end 4A of the shell 4. The seal 2 only permits liquids, air, vapor and aerosol to exit the electronic cigarette through the vapor passage tube 11 and prevents them from passing through the impermeable walls of the vapor passage tube 11.

[0021] The device may be any height and any width, so long as it is proportional to the electronic cigarette to which it is attached. The seal 2 may be made of metal, plastic, stainless steel and elastomers or other materials that will keep a seal inside the shell 4 between the shell 4 and the vapor passage tube 11. The vapor passage tube 11 may be made of metal, plastic, stainless steel, PVC or any other materials that are incollapsible or that will not crush easily. The outer covering 6 may also be treated with glitter, fur, leather or other decorative or non-slip grip elements.
