Background

Before matches, fires were typically started by means of striking iron or steel on flint, or rubbing two pieces of wood together. The first match was created in 1805 by a French chemist named Jean-Louis Chancel. It was difficult to ignite and released strong, smelly fumes when the head was finally lit. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface.. The first successful friction match was invented in 1826 by John Walker, an English chemist and druggist from Stockton-on-Tees, County Durham.

The user can grasp one end of the match and swipe the coated end to ignite the coated end of the stick. The fire can then be used for a desired purpose or until the flame reduces the length of the stick such that the flame starts to bum the user's fingers, which-ever comes first. An important aspect of matches is the advantage of being able to hold the match a safe distance from the flame. A limitation of matches is the amount of time the user has to use the flame.

A lighter is a portable device which generates a flame, and can be used to ignite a variety of items. It consists of a metal or plastic container filled with a flammable liquid or compressed gas, a means of

1

SUBSTITUTE SHEET (RULE 26) ignition to produce the flame and some provision for extinguishing the flame. Alternatively, a lighter can be powered by electricity, using an electric arc or heating element to ignite the target.

The first known lighters were constructed in 16^1,1 Century. Converted flintlock pistols used gunpowder that lit a small tinder bundle. In 1662, the Turkish traveler Evilya Celbi admired the lighters manufactured in Vienna as a member of an Ottoman diplomatic mission. Evilya noted “Enclosed in a kind of tiny box are tinder, a steel, sulfur and resinous wood. When struck, just like a firearm wheel, the wood bursts into flame. This is useful for soldiers on campaign.”

A German chemist named Johann Wolfgang Dobereiner invented a device commonly known as Dobereiner's Lamp in 1823. This lighter worked by passing flammable hydrogen gas, produced within the lighter by a chemical reaction, over a platinum metal catalyst which in turn caused it to ignite and give off a great amount of heat and light. It has been noted that they were difficult to use and dangerous.

In 1903 Carl Auer von Welsbach patented a material he called ferrocerium, a synthetic alloy that produces a very hot bright spark when struck. This metal mixture, which eventually came to be referred to as “flint,” made it possible for lighters to be portable. This spawned a variety of easy to use pocket lighters. The first novelty lighter was introduced by Louis Aronson in 1910, founder of Ronson Lighters. The lighter was called the Pist-O-Liter and closely resembled a long -barreled pistol, with the trigger releasing the flame.

Lighters were also made from bullet casings during World War I. These lighters were more discreet than matches, which were notorious for causing a huge spark which could give away a soldier’s position in the dark. The first automatic lighter, the Banjo, was created by Ronson Lighters in 1926. It was silver, oddly shaped, and had an extremely popular slogan: “Push, it’s lit; Release, it’s out.”

A notable reusable lighter, the Zippo, was invented by George G. Blaisdell in 1932. A small box shaped device with a hinged lid which covers a flint wheel and a wick. It's simple design allows the user to light the wick by rotating the wheel with a finger. After lit, the user can grasp the lower portion of the lighter away from the flame according to preference and use the flame until it has fulfilled it's purpose or until the fuel is gone. To extinguish the flame, the user can close the lid.

A Trench company called Feudor invented the first disposable lighter in 1961. This lighter was named “The Stick” until eventually being bought out by Gillette and renamed “The Cricket.” The first BIC lighter came out in 1973. Their disposable lighter was a direct answer to Gillette’s Cricket, which at the time was the only disposable lighter on the market. The BIC lighter’s reliability, affordability, safety features, and clever “Flick My BIC” marketing made it an instant hit.

The advent of disposable lighters created a market for disposable lighter cases. Lighter users desire a custom design on a case, or a case that has a useful function. Most lighter case intellectual protection is geared toward a unique design aspect, however some utility patents have been filed.

Omokhuale Omokhodion was granted US 10794594 on Oct 6^1,1 2020 for a Shotgun Shell Lighter Case. The disposable lighter fits inside a shotgun shell design case with a hinged lid. On May 25 ^|J|

SUBSTITUTE SHEET (RULE 26) 1982, Victor Lonsmin was granted US 4330954 for a lighter case that features an "interesting" Film Strip operated via a tab pulled by the user.

An innovation who's eventuality was certain is the Bottle Opener + Lighter Combination. On Feb 15^1,1

1983, Lester Miller introduced US 4373223 which features a Bottle Opener incorporated on the bottom of the lighter case. US4854856A shows a cavity to fit a disposable lighter in the handle of a conventional bottle opener. A combination lighter case and opener for both crown cap bottles and tab top cans is disclosed in US4923392A by John L. Moynihan, III. US 4799877 shares a child safety barrier to the gas lever.

Introduction

My invention, an Ergonomic Safe Bum Lighter Case is designed to be combined with a lighter to create a new device. The device offers a user different ergonomic and bum safe grip options. The lighter, when properly inserted into the Safe Bum Case, moves laterally within the case's cavity. While the lighter is being pushed inside the cavity, a gas lever of the lighter enters a housing that covers a top portion of the Safe Bum Case. A ramp like structure of the housing depresses and then holds down the lighter's lever. The user can subsequently rotate a spark wheel choosing from a variety of methods. For example, the user can hold the device with one hand and rotate the spark wheel with any finger of the other hand, an ergonomic advantage.

While using the flame, the user can grip near a bottom end of the case before applying the flame to a desired surface. Increased distance between the fingers and flame, compared to available grip positions of conventional lighter case design, is a bum safety advantage. There is another ergonomic grip advantage. This is because conventional lighter cases demand the user to tightly grip the case body horizontally while also squeezing the gas lever of the lighter vertically. The Safe Bum Case can be used while gently grasping it's body horizontally, as one might naturally handle an inanimate object of similar size.

To deactivate the gas lever, the user pushes the lighter in an opposite direction within the case. A distinct feature is a clicking sound the lighter/case makes when activating and deactivating the lighter. The clicks can be utilized to help distinguish the state of the lighter. Some embodiments have finger sized hole/s inset on the side of the case which allow the user to make contact with the lighter through the case to set or unset the gas lever.

Other embodiments are designed to set the gas lever in a state resembling a neutral equilibrium. A small impact on case or gentle push causes the gas lever to unset itself. Yet other embodiments enhance child safety. For example, the lighter needs to be simultaneously pushed vertically into the case and then horizontally to set the gas lever. Other designs offer limited flame time. Yet further considerations involve a container or useful tool incorporated into or onto the exterior of the lighter case.

Incorporating innovative design and safety features, the Ergonomic Safe Bum Lighter Case redefines the user experience, offering a seamless blend of functionality, convenience, and heightened safety in

Detailed Description

Specification (Figs. 1- 14)

Fig. 1 is an isometric front view of an Ergonomic Safe Bum Lighter Case 100 according to an embodiment of the invention. The Safe Bum Case 100 is constructed from a solid material such as, but not limited to, injection molded plastics/materials, mbber or a variety of metals or metal alloys. Some embodiments combine different materials constmcting different parts of the case. The Safe Bum Case 100 features a Pivot Cavity 210, a Gas Lever Depression Housing 212, a Gas Lever Depression Ramp 214 and a Gas Lever Depression Ledge 216. The Safe Bum Case 100 can be

4

SUBSTITUTE SHEET (RULE 26) independently designed to specifically fit the variety of lighters sold in the marketplace.

The Pivot Cavity 210 is configured such that the lighter fits inside the case. The Pivot Cavity 210's top to bottom dimension is comparable to the top to bottom dimension of the lighter. This dimension can vary according to specific uses. That is, it can be shorter, the same size or taller than the lighter. The Pivot Cavity 10's side to side dimension is comparable to the side to side dimension of the lighter, such as with conventional lighter case designs. The lighter cannot move side to side within the case.

The Pivot Cavity 210's front to back inner cavity dimensions reflect a narrower bottom that is approximately the same size as the front to back dimension of the bottom of the lighter. The Pivot Cavity 210's top front to back dimension is greater than the front to back dimension of the lighter. The Pivot Cavity 210 allows the inserted lighter to pivot within the case. The bottom of the lighter remains fixed while the top of the lighter moves laterally from front to back or from back to front. The lighter acts as a lever arm in a lever system where the bottom of the lighter is the fulcrum.

The Depression Housing 212 is a cavity on the top of the Safe Bum Case 100. The Depression Housing 12 covers a back portion of the top of the Safe Bum Case 100. The Depression Housing 212 is precisely configured such that the gas lever of a properly inserted lighter will fit inside it. Within the Depression Housing 212 is the Depression Ramp 214. The Depression Ramp 214 is a ceiling on the inside of the Depression Housing 212 which slopes down from front to back. The gas lever of the lighter can engage the ramp. The slope may be planer, curved or spherical. When the top of the lighter is pushed from front to back toward the Depression Housing 212 the lighter's lever will depress.

The angle of the ramp considers the pressure of the lighter's spring. When the lighter lever is in contact with the Depression Ramp 214, the case and lighter lever are in an unstable state in relation to each other. Without an external force acting on the lighter with respect to the case, the lever will not remain in contact with the Depression Ramp 214. The energy of the depressed lighter spring causes the gas lever to disengage from the Depression Housing 212.

The Depression Ledge 216 is a planer, curved or spherical ceiling within the Depression Housing 212. The angle of the surface with respect to the vertical axis can vary. The height of the Depression Ledge 216 with respect to the bottom of the Pivot Cavity 210 is approximately the height from the bottom of the lighter to the top of it's gas lever when the gas lever is depressed.

When the lighter lever has been pushed into the Depression Housing 212, it will engage the Depression Ramp 214. The farther the lighter is pushed into the Depression Housing 212, the more the gas lever will depress. When the lever of the lighter is in contact with the Depression Ledge 216, the device constituting the Safe Bum Case 100 and the lighter are in a stable state of equilibrium. The lighter's lever will remain depressed without external force acting on the lighter with respect to the case.

Fig. 2 is a front view of the Safe Bum Case 100 of Fig. 1 according to an embodiment of the

5

SUBSTITUTE SHEET (RULE 26) invention. Fig. 3 is a cross-sectional side view of the case of Fig. 1 according to an embodiment of the invention. The thickness of the case is sufficient to firmly support the lighter as it is pushed within the case.

Fig. 4 is a plan view of the Safe Bum Case 100 of Fig. l.The distance between the front inside edge of the Pivot Cavity 210 and the front inside edge of the Depression Housing 212 is greater than the front to back dimension of the lighter it is designed to work with. In other words, when inserted from the top, the lighter fits into the case.

Fig. 5 is a cross-sectional side view of the Safe Bum Case 100 after a Disposable Lighter 50 has been inserted according to an embodiment of the invention. The Lighter 50 has a Gas Push Lever 52, a Spark Wheel 54 and a Gas Reservoir 56. The Push Lever Spring 58 (not pictured) is located underneath the Gas Push Lever 52. The Lever Spring 58 compresses when the user pushes down on the Gas Lever 52. When the Lever Spring 58 is compressed, gas will flow out of the top of the Lighter Reservoir 56. A Flame Guard 60 protects the user from interacting with a lower portion of a flame.

The Spark Wheel 54 is a cylinder that spins on an axle and is partially made of the material ferrocerium. Ferrocerium, described in the background section, will emit sparks when fiction is applied to it's surface. To operate the lighter without the case, the user rotates the Spark Wheel 54 while simultaneously squeezing the body of the lighter, then squeezes the Gas Lever 52 to ignite the flame. To prolong the flame's duration to preference, the user continues gripping the Gas Lever 52 vertically while squeezing a body of the Lighter 50 horizontally. To extinguish the flame, the user releases the Gas Lever 52.

Fig. 6 is a cross-sectional side view of the Safe Bum Case 100 with a Lighter 50 inserted and activated or set according to an embodiment of the invention. When the Lighter 50 is activated, the Gas Lever 52 is in contact with the Depression Ledge 216. The Gas Lever 52 is compressing the Lever Spring 58 and Lighter Gas 62 is flowing out of the Gas Reservoir 56.

Fig. 7 is an isometric front view of a Spark Wheel Indent Ergonomic Safe Bum Lighter Case 110 according to an embodiment of the invention. The Wheel Indent 218 prevents the Spark Wheel 54 from coming into contact with the Depression Housing 212 when the lighter is set. The Lighter 50 may be constmcted such that the outer back portion of Spark Wheel 54 extrudes farther, in the front to back dimension, than the edge of the Flame Guard 60, over the Gas Lever 52. The Wheel Indent Case 110's Spark Wheel Indent 218 allows penetration of the Spark Wheel 54 into the top of the Depression Housing 212. This design facilitates the reception of a larger portion of the Gas Lever 52 into the Depression Housing 212.

The notch, Wheel Indent 218, is located on the upper inside portion of the Depression Housing 212. It's side to side width is longer than the side to side width of the Spark Wheel 54. Wheel Indent 218's front to back depth is longer than the distance between the outside edge of the Spark Wheel 54, over the Gas Lever 52, and the inside edge of the Flame Guard 60. The edges of the Flame Guard 60 make

6

SUBSTITUTE SHEET (RULE 26) contact outside the Wheel Indent 218 when the lighter is pushed into the Depression Housing 212 and the Gas Lever 52 is set by means of the Depression Ledge 216.

Fig. 8 is a side view of a Finger Hole Ergonomic Safe Bum Lighter Case 120 according to an embodiment of the invention. The Lighter Push Hole 220 is an opening that allows the user to push the Lighter 50 to a different position inside the case with a finger or thumb. It's height or location along the vertical axis can vary. The opening is large enough to insert a finger or thumb while small enough to retain the structure of the case. Fig. 9 is an isometric rear view of the case of Fig. 8.

Fig. 10 is a side view of a Multi Hole Ergonomic Safe Bum Lighter Case 130 according to an embodiment of the invention. The Secondary Lighter Push Hole 222 is an opening located on the front side of the case, opposite the Depression Housing 212. Similar to the Lighter Push Hole 220, it's height or location along the vertical axis can vary. The opening is large enough to insert a finger or thumb while small enough to retain the described stmcture of the case.

In this embodiment, the opening is at the top of the case. Therefore, the Secondary Push Hole 222 does not manifest as an enclosed hole, rather a depression in the upper rim of the case. Additional holes for alternate uses such as on the bottom of the case or on the sides for an ergonomic grip are other design options. An alternate configuration for the holes provides an ergonomic grip or finger sized indentations intended to fit the user's grip.

Fig. 11 is a cross-sectional side view of a Foam Bottom Ergonomic Safe Bum Lighter Case 140, according to an embodiment of the invention. The vertical height of the Pivot Cavity 210 is slightly larger than the cases previously described. A Lighter Level Depression Foam 224 is located at the bottom of the Pivot Cavity 210. It may be attached to the Pivot Cavity 210 or may be removable. The Depression Foam 224 is comprised of a springy, spongy or soft material that will compress when force is applied, and return to it's original volume when the force is removed. Such materials include, but are not limited to, liquids, polymers, foams, gels, colloids, granular materials and rubbers.

The thickness of the Depression Foam 224 and the extended vertical height of the Pivot Cavity 210 are a function of the density of the material. When the Depression Foam 224 is fully compressed by pushing the lighter down into the case, it's compressed vertical height is similar to the vertical length adjustment of the Pivot Cavity 210. When compressed, the structure of the case and the compressed foam holds down the Gas Lever 52.

Without pressing downward, lateral pressure on the lighter in the direction of the Depression Housing 212 will not cause the Gas Lever 52 to engage the Depression Ramp 214. This is because the level of the top of the lighter lever is higher than the gas lever entry level of the Depression Ramp 214. The edge of the Gas Lever 52, or the edge of the lighter, will make contact with the area above the Depression Ramp 214 entry point on the Depression Housing 212.

The additional pressure from the foam added to the pressure from the Lighter Spring 58 can affect the

7

SUBSTITUTE SHEET (RULE 26) design of the Depression Housing 212. The workable angle of the Depression Ramp 214 and or the size of Depression Ledge 216 can be adjusted to accommodate the total pressure such that they fulfill their duties. Because the user must use additional force to push the Lighter 50 down... and subsequently hold it down.... while pivoting the Lighter 50, more force is required to activate the Lighter 50.

The design allows the lighter's Gas Lever 52 to properly engage the Depression Ramp 214 only when a downward vertical pressure is applied along with a subsequent lateral pressure to the Lighter 50. The Lighter 50 is pushed down into the Pivot Cavity 210, held and then pushed over toward the Depression Housing 212 to set the lighter's Gas Lever 52.

Fig. 12 is a cross-sectional side view of a Double Foam Bottom Ergonomic Safe Bum Lighter Case 150 according to an embodiment of the invention. The Double Foam Case 150 is similar to the Foam Bottom Case 140 in that the vertical height of the Pivot Cavity 210 is elongated. The distance elongated is a factor of the density of the materials, their properties and desired results. A Secondary Lighter Level Depression Foam 226 can be located above, below or next to the Depression Foam 224 at the bottom of the case. In this illustration, it is located below the Depression Foam 224. The Secondary Foam 226 is comprised of a spongy or soft material that will compress when force is applied. Such materials include, but are not limited to, liquids, polymers, foams, gels, colloids, granular materials and rubbers.

A useful class of foam termed "memory foam" displays viscoelastic properties. Viscoelasticity materials exhibit both viscous and elastic characteristics when undergoing deformation. Visco (from viscous) means it moves, somewhat reluctantly, when force is applied; elastic means it returns to its original shape when the force is removed. If constant force is applied to a piece of viscoelastic foam of constant area (so the stress is constant), it keeps deforming slowly over a period of time, a property known in material science as "creep" .

The combined compressed thickness of the Depression Foam 224 and the Secondary Foam 226 is less than the adjusted vertical length of the Pivot Cavity 10. The properly inserted lighter fits underneath the Depression Housing 212 in the set position when both foams are compressed without depressing the lighter's Gas Lever 52. However, when the lighter is initially pushed down and over so that lighter lever engages the Depression Ramp 214 and then the Depression Ledge 216, the Depression Foam 224 can compress first.

When the Secondary Foam 226 is a viscoelastic material, the Secondary Foam 226 will then start to creep and give way to the pressure from the lighter's spring acting on the lever of the lighter. That is, the spring from the lighter uses it's stored energy to act on the Secondary Foam 226, compressing it as it pushes the lighter lever against the Depression Ledge 216. When the Secondary Foam 226 is compressed sufficiently, the Gas Lever 52 becomes disengaged. The Double Foam Case 150 will only depress the lever of the lighter for a fixed amount of time. More than two layers of foam may be arranged in various configurations to attain different results.

SUBSTITUTE SHEET (RULE 26) Fig. 13 is a cross-sectional side view of a Flick Assist Ergonomic Safe Bum Lighter Case 160 according to an embodiment of the invention. The Flick Assist Case 160 presents an alteration to the Depression Housing 212 as described in Fig. 1. The top surface of the Depression Housing 212 slopes down toward to the rear of the case. The Flick Assist Ramp 228 is an incline that allows more room for the user to activate the Spark Wheel 54 of the lighter. The slanted surface can be flat, planar, curved or a partial spherical shape. The Flick Assist Ramp 228 may be constructed of a different material than the rest of the case and attached onto or into the Depression Housing 212. A soft material can increase user comfort for particular spark wheel spinning strategies. A material with a slick surface can reduce wear by friction on user body parts.

Fig. 14 is a side view of a User 30 holding a Finger Holes Flick Assist Ergonomic Safe Bum Lighter Case 170 according to an embodiment of the invention. The Holes Assist Case 170 combines the features of Fig. 10 and Fig. 13. The Lighter Push Hole 220 is on the opposite side of the case to the Secondary Push Hole 222. The Flick Assist Ramp 228 is the slope on the top surface of the Depression Housing 212 that allows a greater volume for the user to access the Flint Wheel 54. The User 30 is gently grasping the Holes Assist Case 170 across one dimension a safe distance from a Lighter Flame 64.

There are other possible configurations that involve peripheral modifications to the outside structure of the case. A tool such as bottle opener or screwdriver may be incorporated into the design at various locations. A detachable storage container that screws or clips onto the bottom of the case is another design. The case may have an interior screw thread that screws over the case's exterior screw thread or vise versa.

Another design incorporates a cavity alongside the outside of the case for storing desired items. A further arrangement incorporates a pedestal on the bottom of the case that extends further horizontally than the outside edge of the bottom of the Safe Bum Case it is attached or molded to.

Operation ( Figs. 5 - 14 )

The basic operation of the Safe Bum Case requires 5 operational steps after inserting the Lighter 50. 1. Push the Lighter 50 laterally inside the case. 2. Grasp the case according to preference. 3. Rotate the Spark Wheel 54 to light the flame. 4. Use the flame for the desired purpose. 5. Push the Lighter 50 in the opposite lateral direction to unset the Lighter Lever 52 and thereby extinguish the flame. Some embodiments allow the user to tap or shake the Safe Bum Case to unset the gas lever.

The user inserts the Lighter 50 into the Safe Bum Case in a similar fashion as performed with conventional lighter cases. The bottom goes in first. However the rotational position, chosen by the user, offers different effects. If inserted with the Gas Lever 52 on the opposite side to the Depression Housing 212, the case cannot activate the Gas Lever 52. The Gas Lever 52 cannot come into contact the Depression Ramp 214. Therefore the Safe Bum Case 100 functions like a conventional lighter

9

SUBSTITUTE SHEET (RULE 26) case.

Fig. 5 illustrates the position of the Lighter 50 after it has been inserted into the Safe Bum Case 100 in preparation to activate the Lighter 50. A cross-sectional view of the Safe Bum Case 100 avails the position of the Lighter 50. Because the Gas Lever 52 is adjacent to the Depression Housing 212, the Gas Lever 52 can come into contact with the Depression Ramp 214. The Lighter 50 can be activated by the Safe Bum Case 100 if the user pushes the top of the Lighter 50 toward the Depression Housing 212 while securing the Safe Bum Case 100.

Fig. 6 illustrates the case and lighter of Fig. 5 after the user has pushed the Lighter 50 laterally, toward and into the Depression Housing 212, so that the Lighter 50 is active. An aspect to operating and activating the Gas Lever 52 is that the case/lighter will make a clicking sound when the Gas Lever 52 is set into the Depression Housing 212. This first click alerts the user that Lighter Gas 62 is flowing out of the top of the lighter.

The Gas Lever 52 is depressed and set by means of the Depression Ledge 216. The Lever Spring 58 is compressed and Lighter Gas 62 is flowing out from the top of the Lighter 50. To light the flame, the user can choose from a variety of strategies. For example, held near the bottom of the case, away from the imminent flame. The user can then rotate the Spark Wheel 54 to ignite the Lighter Gas 62. There are options for rotating the Spark Wheel 54. For example, any finger from the hand that is not holding the Safe Bum Case 100 can be used. Alternately, an object such as a coin or key can be used to make contact with and rotate the Spark Wheel 54.

When the flame is ignited, the user is free to gently grasp the Safe Bum Case 100 in alternate ways to attain the desired result. A safe distance away from the flame, similar to a holding a match that has been recently ignited, is a notable option for the user. When the user wishes to extinguish the flame, the top of the Lighter 50 can be pushed in the opposite lateral direction used to activate the Lighter 50. The case/lighter will make a second clicking sound which notifies the user that the Lighter 50 is unset from the Depression Ledge 216. If a click hasn't been heard... or vibration felt, it is not certain that the lighter has been deactivated.

Because the Depression Ledge 216 can be designed to hold the Gas Lever 52 down in a state resembling a neutral equilibrium, a small force or vibration can disengage the Gas Lever 52 from the Depression Ledge 216. Therefore, to deactivate the Lighter 50, the Safe Bum Case 100 can be tapped or shaken. A relatively small force can encourage the Gas Lever 52 to make contact with the Depression Ramp 214. The Lighter 50 cannot remain in this position in relation to the Safe Bum Case 52 because they are in an unstable state. The force of friction is not greater than the lateral force vector. Therefore, the energy stored in the Lever Spring 58 pushes the Gas Lever 52 against the Depression Ramp 214.

The top of the Lighter 50 is pushed laterally until the Lever Spring 58 has released it's stored energy. This spontaneous movement makes the second clicking sound when the Lighter 50 makes contact

10

SUBSTITUTE SHEET (RULE 26) with the inside front of the Pivot Cavity 210. When the Lever Spring 58 is not compressed, the Lighter 50 is not active.

The operation of the Wheel Indent Case 110 of Fig. 7 is the same as the operation of the Safe Bum Case 100. However, the front to back distance of the Depression Housing 212 can be longer. This makes possible a longer Depression Ramp 214 which can make it easier to pivot the Lighter 50 inside the Pivot Cavity 210. There is a mechanical advantage because the Gas Lever 52 travels a longer distance along the ramp than the distance the Gas Lever 52 is depressed. A longer Depression Ledge 216 is also possible which can make the set position, where the Gas Lever 52 is pressed down by the structure of the case, more stable.

The Finger Hole Case 120 of Fig. 8 and Fig. 9 present the user an alternate location to push the Lighter 50 within the Pivot Cavity 210. When the Lighter Push Hole 220 is located on the same side of the case as the as the Depression Housing 212, the user can deactivate the Lighter 50 by making contact with the Lighter 50 through the Lighter Push Hole 220, then pushing it. When the Lighter Push Hole 220 is located on the opposite side of the Depression Housing 212, the user can use the hole to activate the Lighter 50. An alternate location for the Lighter Push Hole 220 is on the bottom of the case. This location can assist the user when dislocating the Lighter 50 from the case.

The Multiple Hole Case 130 of Fig. 10 illustrates a Safe Bum Case that has more than one lighter access push hole. The user can use the Secondary Push Hole 222 to push the Lighter 50 to activate the Lighter 50. The Secondary Push Hole 222 can also be used to hold the Lighter 50 in a stable state while spinning the Spark Wheel 54. A smaller Depression Ledge 216 can make the Lighter 50 easier to deactivate, but harder to maintain position while spinning the Spark Wheel 54. The user can use the Lighter Push Hole 220 to deactivate the Lighter 50.

The Foam Bottom Case 140 of Fig. 11 is intended to provide a safeguard against unintended or underage lighter activation. An added step and more force required to activate the Lighter 50 are design strategies employed to achieve the safeguard. The user must push the Lighter 50 down into the Depression Foam 224 so that the top of Gas Lever 50 is level to or lower than the entry point of the Depression Ramp 214. While holding down, the top of the Lighter 50 is then pushed into the Depression Housing 212. The added step and force required, pushing and holding the lighter into the Foam Case 140, is a strategy for discouraging unforeseen circumstances or children from activating the lighter.

The Double Foam Case 150 of Fig. 12 illustrates another safety feature. The ability to deactivate the Lighter 50 without user action. The user begins operating the Double Foam Case 150 in conjunction with the Lighter 50 in a similar fashion that is described for the Foam Case 140. That is, the user must push the Lighter 50 down into the case and hold it, then pivot the Lighter 50 toward the Depression Housing 212.

After the Lighter 50 is properly set inside the Depression Housing 212, there is a limited amount of

11

SUBSTITUTE SHEET (RULE 26) time that the user can utilize the Lighter Gas 60. The user can ignite the flame with the Spark Wheel 54, and then use the flame until the Double Foam Case 150 deactivates the Lighter 50. The viscoelastic material compresses and gives way slowly, or "creeps" until the Lever Spring 58 has relaxed and transferred it's stored energy into the Secondary Foam 226.

The Flick Assist Case 160 of Fig. 13 is operated in the same manor as described for the Safe Bum Case 100 in Fig. 5 and Fig. 6. The lighter 50 is inserted with the Gas Lever 52 on the same side as Depression Housing 212. The top of the Lighter 50 is pushed laterally so it pivots inside Pivot Cavity 210 and engages the Depression Housing 212, thereby depressing the Gas Lever 52.

When the user rotates the Spark Wheel 54, the digit used or inanimate object used, will encounter a larger space to operate the Spark Wheel 54 than available for the Safe Bum Case 100. The digit is also also "cushioned" because the flicking motion encounters a greater distance to cease motion. The energy is dispersed into the structure of the Flick Assist Ramp 228 over a time increment as the digit moves down and across the ramp. It is generally easier to ignite the Lighter 50 using the Flick Assist Case 160 than a Safe Bum Case 100.

The operation of the Holes Assist Case 170 ofFig. 14 combines the operational steps of Fig. 10 and Fig. 13. The User 30 can push the Lighter 50 so it pivots inside the Holes Assist Case 170 via the Secondary Push Hole 222 to set the Lighter 50. Then the User 30 can rotate the Spark Wheel 54, made easier by the Flick Assist Ramp 228, to ignite the lighter gas such that it manifests as the Lighter Flame 64. The Holes Assist Case 170 can then be held gently across one dimension, a safe distance from the Lighter Flame 64. Finally, the User 30 can push the Lighter 50 via the Lighter Push Hole 220 so it pivots within the Holes Assist Case 170 to deactivate the Lighter 50.

To operate a Safe Bum Case that has the bottle opener incorporated into the bottom of the case, the user can grasp the top of the case, insert the bottle cap into the bottle opener and use leverage advantage to release the cap. To operate a Safe Bum Case with the container located at the bottom, the user can grasp the case above the container and screw off the container. To operate a Safe Bum Case with the cavity along side the exterior of the case, the user can insert the desired item/s into the cavity. A Safe Bum Case with the pedestal is operated by being stood upright.

Advantages ( Figs. 5 - 14 )

There many advantage a Safe Bum Case offers users. There is an ergonomic advantage because the user has different options for grasping the case and setting it, then also while rotating the spark wheel to ignite the flame. A design considering greater access to the spark wheel of the lighter is an ergonomic advantage. Another ergonomic advantage is the ability to hold the case gently across one dimension while the using the flame of the lighter. Lighter access holes in the Safe Bum Case offer operational, convenience and safe bum advantages. A clicking noise that denotes lighter activation and subsequent deactivation is an operational and safety advantage.

12

SUBSTITUTE SHEET (RULE 26) The option to hold the Safe Bum Case an appreciable distance from the flame is bum reduction safety advantage. A child-proof safety advantage is the un-intuitive operation that requires multiple steps to correctly operate the case. A further child-proof safety and unintended activation advantage is an added step and greater force required to activate the lighter. A bum time safety advantage limits the time the Safe Bum Case will push down on the lighter lever. Attachments or elements incorporated into the exterior of the case is a convenience advantage.

The action of depressing the Gas Lever 52 of the Lighter 50 is easier because the horizontal distance of the Depression Ramp 214 is longer than the vertical distance the Gas Lever 52 travels, a mechanical advantage. The mechanical advantage can be increased when the notch, Wheel Indent 218 (Fig. 7), in the Safe Bum Case's housing allows for greater penetration of the Spark Wheel 54 and Gas Lever 52 into the Depression Housing 212. This can facilitate a larger Depression Housing 212 and thus a longer Depression Ramp 214. Lighter activation stability can be enhanced with a longer Depression Ledge 216.

The clicking noises that can be heard, and felt, introduces a useful instructional habit. One reason being, without consciously acknowledging the clicks or vibration, the Lighter 50 could still be engaged. The Lighter 50 could still be activated with a flame and similar to a candle, a possible fire hazard. Secondly, a Lighter Flame 64 has a fragile existence, it can easily be distinguished by a small disturbance such as a vibration or air movement. The user could mistakenly believe the Lighter 50 is deactivated. Although an extinguished flame is not a fire hazard, the Safe Bum Case will "eat" the Lighter 50, an unnecessary expense. The Lighter Gas 62 will flow out of the Lighter 50 until the Gas Reservoir 56 is expired.

The ability to grasp the Safe Bum Case 100 of Fig. 5 in a variety of ways while choosing from a variety of ways to set or activate the Lighter 50 is an ergonomic advantage. Both hands can be used which reduces stress on muscles. There are a variety of ways to rotate the Spark Wheel 54, an ergonomic advantage. For example, one hand holding the Safe Bum Case 100 while using a digit from the other hand reveals 10 different methods for igniting the flame. Alternate spin strategies can reduce wear on particular muscle groups and skin areas which is an ergonomic advantage.

The Flick Assist Ramp 228 described in Fig. 13, is designed to increase the space available for the user to operate the Spark Wheel 54, an operational and ergonomic advantage. The Flick Assist Ramp can absorb more energy from the flicking motion.

After the flame is ignited (Fig. 14), the user can then grasp the Safe Bum Case 100 in a variety of ways according to preference. It is ergonomically advantageous to gently grasp the case laterally as opposed to the common method of squeezing the conventional case laterally and vertically. Comparably, there is a reduction in muscles used as well as force applied. A bum reduction advantage is available if the Safe Bum Case 100 is grasped an appreciable distance from the flame.

Operational, convenience and bum safety advantages are attained when the User 30 has alternate

13

SUBSTITUTE SHEET (RULE 26) ways to operate the case/lighter device. The user can use the Lighter Push Hole 220 described in Figures 8 and 9 to conveniently activate or deactivate the lighter. A gripping strategy can incorporate the gentle grip with a finger near the Lighter Push Hole 220. The finger is then available to conveniently activate or deactivate the lighter without altering the grip.

Since the Lighter Push Hole 220 is can be located an appreciable distance from the flame, bum risk is minimized when deactivating the Lighter 50. It can be convenient to use the Secondary Push Hole 222 described in Fig. 10 to activate the lighter. It not only can be used to push the Lighter 50, it can also be used to help stabilize the Lighter 50 within the case while rotating the Spark Wheel 54.

The multiple non-intuitive steps needed to activate the Lighter 50 is a child-proof advantage. The user must know to insert the lighter a specific way into the case, push the lighter specific way, set the Lighter Lever 52 (Fig. 6), then keep the lever set while igniting the flame. The foam bottom case of Fig. 11 increases the difficulty of activation, an additional child-proof advantage. It requires the user to compress the foam while activating the lighter. Thus, lighter activation requires an extra step plus extra force. When viscoelastic foam described in Fig. 12 is used as the foam, in one or more layers, the flame time can be limited. The Double Foam Safe Bum Case 150 will automatically extinguish the flame, a flame exposure duration safety advantage.

Different combinations of the alternate designs, such as illustrated in Fig. 14, enhance ergonomics and operability according to user preference. In this embodiment, the user can use the Secondary Push Hole 220 to activate the lighter, take advantage of Flick Assist Ramp 228 while igniting and use the Lighter Push Hole 220 to deactivate the Lighter 50.

The convenience advantage of having the Safe Bum Case with a bottle opener is well established. The separate container that screws or clips on the bottom of the Safe Bum Case is a storage advantage, as is the cavity alongside the case. Incorporating the pedestal on the bottom of the Safe Bum Case so that it may easily be placed in an upright position is a convenience and organizational advantage.

Summary

Before matches were invented in the early 1800s. Steel, Flint and Tinder or Friction between two pieces of wood were the primary methods used to start a fire. Matches allow the user to grasp it's handle an appreciable distance from the flame. The material called ferrocerium was invented in the 1903. This material emits sparks as a result of friction between it and a suitable material. Ferrocerium sparked the dawn of modem lighters.

Various refillable hand held lighters, such as Zippos, dominated the marketplace until 1961 when disposable lighters were introduced. Cases for these lighters have been popular with users. The cases are constructed to snugly fit the lighters. Most intellectual protection revolves around a design aspect. The shotgun shell shaped case, the case with a simple "interesting" film strip, the bottle opener case and the child-proof case are existing utility designs.

14

SUBSTITUTE SHEET (RULE 26) The Safe Bum Case introduces lateral innovations to the conventional design. The case offers the user ergonomic and safe ways to hold the lighter case while operating the lighter. The user is not required to squeeze the case with more force and in more directions than a normal grasp holding a lighter case sized object. The user can choose from a variety of options to set the gas lever and to rotate the spark wheel of the lighter. The user can hold the case in a variety of positions while using the flame. Holding the Safe Bum Case a safe distance from the flame to limit unwanted bums is a noteworthy strategy.

A clicking sound and vibration denote changes in states of activation. Finger sized holes and/or modifications to the case can be used to enhance operability and provide safe bum options. Unintuitive steps for activation is a child-proof advantage that is enhanced with a foam like material in some embodiments. Safety is further enhanced with additional foam layers that limit the duration of lighter activation. A tool such as a bottle opener, storage cavity or pedestal may also be included in the design.

The Safe Bum Case has a lighter cavity that is larger than the housing of the lighter. The lighter can move or pivot laterally within the case for different effects. The way the lighter is inserted into the Safe Bum Case also offers options such as the ability to operate. The Safe Bum Case has the housing that partially covers the top of the case which the lever of the lighter precisely fits into. When the lighter is moved or pushed laterally within the case, the ramp within the housing pushes the lighter lever down as the lighter's position is altered inside Safe Bum Case's cavity.

The ledge within the housing holds the lighter's lever down after it is pushed past the ramp. A clicking sound can be heard when the lighter lever is set. With the lighter lever held down by the case, the user can grasp the Safe Bum Case according to preference while rotating the lighter's spark wheel to light the flame. Two hands/fingers used or using an inanimate object to rotate the spark wheel are options. The user can then choose a different grip strategy while utilizing the flame for their desired purpose. The case holds the lighter lever down to prolong the flame.

There are embodiments that feature one or more finger sized holes in the side/s of the case for pushing the lighter to different positions inside the case. For example, a hole on the side of the case opposite the housing can be used to activate the lighter. A hole on the side of the case that the housing is on can be used to deactivate the lighter. A hole on the bottom of the case can be used for dislocating the lighter from the case. The holes can also be used for stability purposes.

Some embodiments have a relatively small ledge which will "barely" hold the lighter lever down in a stable state. The design encourages easy lighter deactivation. A small jolt such as shaking the case or tapping the case against a surface (non-flammable) releases the lighter lever from the ledge so it engages the ramp. The ramp within the Safe Bum Case is designed so it cannot stably support the pressure from the lighter lever. The compressed spring from the lighter pushes the lighter lever against the ramp and it's energy moves the lighter to an inactive position within the case. The lighter makes a

15

SUBSTITUTE SHEET (RULE 26) useful clicking sound when it makes contact with other side of the case.

Other embodiments use a spring like object, such as foam, to add a step and require more force to activate the lighter. The lighter must be pushed down into the case before and while being pushed laterally in the case. This enhances child-proofability and discourages unintended lighter activation. There are spring-like materials that act like a tire loosing air out of a small hole. A given force takes time to compress these materials. This quality can be utilized to construct a Safe Bum Case that limits the time the lighter is activated.

Yet other embodiments incorporate modifications to the exterior structure of the housing that receives the lighter lever. For example, the ramp on the top of the housing that allows greater access to the lighter's spark wheel. Other examples are an indent that compensates extra space for the spark wheel of the lighter to rotate without making contact with the case or an indent designed to remove bottle caps. There are also ways to modify the structure of the case, not pictured, that incorporate ways to store small useful items or provide a pedestal

The Safe Bum Case offers the user mechanical advantage when depressing the lighter lever making the task easier. Ergonomic advantage is gained when less stress and/or use is required of anatomy for a particular task. More than 10 ways to rotate the spark wheel reduces wear on any particular part of the body. Eliminating multiple direction tight squeezing with one hand is an ease on the muscles when rotating the spark wheel.

Sharing the force needed to rotate the spark wheel between two hands is another ergonomic advantage. Finger sized holes in the case which allow the user alternate access to the lighter is a convenience, ergonomic and safe bum advantage. Deactivating the lighter without altering the grip a safe distance from the flame with the finger sized hole is a way operation is eased and bum prospect is lessened. The ramp for accepting the motivating digit or object that rotates the spark wheel distributes the energy over a longer distance and reduces impact forces, another ergonomic advantage.

Bum Safety advantage is gained when the user's anatomy is not prone to bum. Grasping the case at an appropriate distance when rotating the spark wheel can reduce bum risk. Grasping the case an appropriate distance from the flame when applying the flame can also reduce the likelihood of a bum.

The clicking noise made when the lighter is deactivated provides a way to double check that the lighter has been deactivated. Spring-like layer/s which require another step and more force enhance the child-proof design and unintended lighter activation. A further safety advantage are the designs that limit lighter activation time. Modifications to the exterior of the case can allow storage, create a tool or create a support which allows the Safe Bum Case to be easily stood upright. Different combinations of designs can be tailored to user preference.
