The present disclosure is directed to snap cap devices configured to be inserted within an associated firearm and which are made from or otherwise include a material configured to release corrosion protection molecules.
Snap caps are known devices that are shaped like a standard firearm cartridge but contain no primer, propellant, or projectile. Snap caps generally serve the same function as dummy rounds, but are different in that dummy rounds are usually made from a real cartridge having its propellant and primer removed but retaining the projectile and casing, while snap caps are designed to be ‘fake’ cartridges from the outset. Snap caps are known to be used to ensure that dry-firing of certain firearm designs does not cause stress and/or impact damage to the firing pin and/or the barrel breech. However, conventional snap caps, especially when fully or partially formed of a metal, can contribute to or not inhibit or prevent corrosion, rust, and/or tarnish when inserted into firearms and firearm components, which firearms and firearm components are commonly made from metal.
In view of the prior art, there remains a need for improved snap cap devices that include one or more components and/or structural features that provide a material which helps protect against rust, corrosion, and tarnishing.
The present disclosed is directed to the use of one or more corrosion protective components to inhibit or prevent corrosion of a firearm.
In one non-limiting aspect of the present disclosure, one or more corrosion protective components can be in the form of a snap cap device that is configured to be inserted in an associated firearm and configured to be made from or otherwise include a protective material configured to release corrosion protection molecules.
In another and/or alternative non-limiting aspect of the present disclosure, there is provided a snap cap device that provides oxidation and/or corrosion protection to a firearm. In one non-limiting embodiment, the snap cap includes a body portion, an internal cavity and a protective material that is formed of or includes a material that releases corrosion protection molecules.
In another and/or alternative non-limiting aspect of the present disclosure, there is provided a snap cap device that provides oxidation and/or corrosion protection to a firearm, wherein the snap cap is configured to be at least partially inserted within a barrel, magazine, chamber, etc. of a firearm and to provide protection against corrosion, tarnish, and/or rust.
In another and/or alternative non-limiting aspect of the present disclosure, there is provided a snap cap device that provides oxidation and/or corrosion protection to a firearm, wherein the snap cap device includes a snap cap body that extends between a first end and a second end of the snap cap device.

As briefly mentioned above, the snap cap device 100 generally includes a snap cap body 102 that extends between a first end 104 and a second end 106. The first end 104 is generally configured to be inserted within the barrel, magazine, chamber, etc. of a firearm. The second end 106 is generally configured to be disposed adjacent a firing pin of the associated firearm when the first end 104 has been inserted in the barrel, magazine, or chamber of a firearm. More generally, the snap cap body 102 is configured to rest in the portion of a firearm where ammunition, such as, for example, a bullet or a shotgun shell, is disposed immediately before firing the firearm. However, it can be appreciated that the snap cap body 102 can be inserted in an ammunition clip or magazine to provide corrosion protection to ammunition, a magazine, etc.
The snap cap body 102 is illustrated as being generally cylindrical in shape. However, the particular shape of the body 102 is non-limiting and any desired shape can be used provided the snap cap is able to be fit within an associated firearm as discussed above. For example, the snap cap body could have a cuboid or conical shape. A hollow interior region or cavity 108 is accessible adjacent the first end 104 of the snap cap body 102 via an opening in the first end 104. The snap cap body includes an end wall 110 that is disposed at the second end 106. When the snap cap body 102 is inserted into an associated firearm, the end wall 110 generally faces the firing pin of the associated firearm. In this regard, the end wall 110 can optionally include a strike wall 112 configured to receive the impact force of the firing pin during a dry-firing event. The strike wall 112 can also be referred to as a false primer, as is known in the art. In some embodiments, the strike wall 112 can be spring-buffered or made from a rubber or soft polymer material to help absorb the impact force from the firing pin during dry-firing. However, such a configuration is non-limiting. The strike wall 112 is generally located in the middle of the end wall 110 and generally has a circular shape; however, this is not required. Generally, the strike wall 112 is formed of a different material from the snap cap body 102 and is configured to be inserted into and/or connected to the snap cap body 102 via a strike wall opening located in the end wall 110.
The second end 106 of the snap cap body 102 can optionally include one or more flanges or stop wall 114 that is disposed fully or partially around the exterior perimeter of the snap cap body. As illustrated in
As mentioned above, the opening in the first end 104 of the snap cap body 102 provides access to a hollow interior region 108. The hollow interior region 108 is generally defined by an interior surface wall 116, and an opposing wall 118 defines an exterior surface of the snap cap body 102. The cross-sectional shape of the hollow interior region 108 is illustrated as being circular; however, other shapes can be used. The cross-sectional area and cross-sectional shape of the hollow interior region 108 is generally uniform along a majority of the longitudinal length of the hollow interior region 108; however, this is not require. As illustrated in

As briefly mentioned above, the snap cap device 200 generally includes a snap cap body 202 that extends between a first end 204 and a second end 206. The first end 204 is generally configured to be inserted within the barrel, magazine, chamber, etc. of an associated firearm. The second end 206 is generally configured to be disposed adjacent a firing pin of the associated firearm when the first end 204 has been inserted in the barrel, magazine, or chamber. More generally, the snap cap body 202 is configured to rest in the portion of a firearm where ammunition, such as, for example, a bullet or a shotgun shell, is disposed immediately before firing the firearm.
The snap cap body 202 is illustrated as being generally cylindrical in shape. However, the particular shape of the body 202 is non-limiting, and any desired shape can be used provided the snap cap is able to be fit within an associated firearm as discussed above. For example, the snap cap body could have a cuboid or conical shape. A hollow interior region 208 is accessible via an opening in the first end 204 of the snap cap body 202, and the end wall 210 is disposed at the second end 106. When the snap cap body 202 is inserted into an associated firearm, the end wall 210 generally faces the firing pin of the associated firearm. In this regard, the end wall 210 can optionally include a strike wall 212 configured to receive the impact force of the firing pin during a dry-firing event. The strike wall 212 can also be referred to as a false primer, as is known in the art. In some embodiments, the strike wall 212 can be spring-buffered or made from a rubber or soft polymer material to help absorb the impact force from the firing pin during dry-firing. However, such a configuration is non-limiting. The strike wall 212 is generally located in the middle of the end wall 210 and generally has a circular shape; however, this is not required. Generally, the strike wall 212 is formed of a different material that then of snap cap body 202 and is configured to be inserted into and/or connected to the snap cap body 202 via a strike wall opening located in the end wall 210.
The second end 206 of the snap cap body 202 also includes a flange or stop wall 214 disposed around the exterior perimeter of the snap cap body. More particularly, the stop wall 214 is radially disposed around the entire circumference of the cylindrical snap cap body 202 adjacent the second end 206 thereof; however, this is not required. The stop wall 214 generally protrudes outward from/parallel to the end wall 210 and outward from/perpendicular to the cylindrical wall of the snap cap body 202. In other words, the stop wall 214 forms an approximate 90 degree angle with the snap cap body 202. In this regard, the stop wall 214 is generally configured to rest against at least a portion of the barrel, magazine, or chamber of an associated firearm in which the snap cap body 202 is disposed, thereby maintaining the end wall 210 in adjacent relation to the firing pin of the associated firearm and preventing the snap cap body from sliding down into an unwanted area of the barrel, magazine, or chamber. However, the means to maintain the end wall 110 in adjacent relation to the firing pin of the associated firearm and prevent the snap cap body from sliding down into an unwanted area of the barrel, magazine, or chamber are non-limiting.
As mentioned above, an opening in the first end 204 of the snap cap body 206 provides access to a hollow interior region 208. The hollow interior region 208 is generally defined by an interior surface wall 216, and an opposing wall 218 defines an exterior surface of the snap cap body 202. The distance between the interior surface wall 216 and opposing exterior surface wall 218 defines a thickness of the snap cap body 202. In some particular non-limiting embodiments, the exterior surface wall 218 is configured to be substantially smooth. In other words, the exterior surface wall 218 is substantially planar along a length of the snap cap body 202 between the first and second ends 204, 206 thereof. As a result, the end wall 210 and stop wall 214 are substantially circular in shape. However, such a configuration is non-limiting. For example, the exterior surface wall 218 can optionally include one or more surface features as described above with respect to the snap cap device illustrated in
As discussed briefly above, the second end 206 of the snap cap body 202 includes one or more vent holes 220. The one or more vent holes 220 are illustrated in
The one or more vent holes 220 can be used to enable the corrosion protection molecules that are released from the protective material to flow between the first and second ends 204, 206 of the snap cap body 202. Such an arrangement is particularly advantageous when the snap cap body 202 is not at least partially formed of a protective material. In such a configuration, powder, pellets, plugs, etc. of material that includes the protective material (not shown) are placed in the hollow interior region 208 and a plug (not shown) is then inserted into the opening on the first end 204 to retain the powder, pellets, plugs, etc. of material that includes the protective material in the hollow interior region 208. The plug can optionally be formed of a porous material that allows the corrosion protection molecules that are released from the protective material to flow through the plug, thereby allowing the corrosion protection molecules to escape the hollow interior region 208 at the first end 204 of the snap cap body 202. The one or more vent holes 220 can be used to allow the corrosion protection molecules that are released from the protective material to flow through one or more vent holes 220, thereby allowing the corrosion protection molecules to escape the hollow interior region 208 at the second end 206 of the snap cap body 202. Generally, the one or more vent holes 220 are sized to prevent powder, pellets, plugs, etc. of material that includes the protective material from passing through the one or more vent holes 220.

Snap cap device 400 includes a snap cap body that is formed of an upper cap body 402 and a snap cap base 403. The upper cap body 402 extends from the snap cap base 403 and includes a first end 404 generally configured to be inserted within the barrel, magazine, chamber, etc. of an associated firearm. The snap cap base 403 includes a second end 406 and is generally configured to be disposed adjacent a firing pin of the associated firearm when the first end 404 of snap cap body 402 has been inserted in the barrel, magazine, or chamber. More generally, the snap cap 400 is configured to rest in the portion of a firearm where ammunition such as, for example, a bullet or a shotgun shell, is disposed immediately before firing the firearm.
The snap cap base 403 includes an end wall 410 disposed at the second end 406. When the snap cap 400 is inserted into an associated firearm, the end wall 410 generally faces the firing pin of the associated firearm. In this regard, the end wall 410 can optionally include an aperture 413 configured to receive a strike wall 412 that is configured to receive the impact force of the firing pin during a dry-firing event. The strike wall 412 is generally located in the middle of the end wall 410 and generally has a circular shape; however, this is not required. Generally, the strike wall 412 is formed of a different material and is a separate component from the upper cap body 402 and is configured to be inserted into and/or connected to the upper cap body 402 via a strike wall opening located in the end wall 410 as illustrated in
The second end 406 of the snap cap base 403 also includes one or more flanges 414 disposed at least partially around the exterior perimeter of the snap cap base 403. More particularly, the one or more flanges 414 are radially disposed around a circumference of the cylindrical snap cap base 403 adjacent the second end 406 thereof. The one or more flanges 414 generally protrude outward from/parallel to the end wall 410 and outward from/perpendicular to the cylindrical walls of the upper cap base 402. In this regard, the one or more flanges 414 are generally configured to rest against at least a portion of the barrel, magazine, or chamber of an associated firearm in which the snap cap 400 is disposed, thereby maintaining the end wall 410 in adjacent relation to the firing pin of the associated firearm and preventing the snap cap from sliding down into an unwanted area of the barrel, magazine, or chamber.
The snap cap base 403 may be composed of a metal material. In some embodiments, the metal material is stainless steel. In other embodiments, the metal material is metal that is softer than the metal of an associated firearm such as, for example and without limitation, copper and copper-alloy. In this way, the metal snap cap base 403 is less likely to damage the metal barrel of a firearm. In one non-limiting embodiment, the metal snap cap base 403 is formed of a material that does not include a protective material.
The snap cap base 403 is configured to receive and connect to upper cap body 402. In some embodiments, the upper cap body 402 is permanently attached to the snap cap base 403. In other embodiments the upper cap body 402 is removably attached to the snap cap base 403 and can be replaced.
In some embodiments, the upper cap body 402 is formed of different material from the snap cap base 403. In one non-limiting example, the upper cap body 402 is composed of a material (e.g., plastic material, silicon, composite material, metal, resin, urethane, wood, etc.) that includes the protective material and the snap cap base 403 is formed of a material that is absent the protective material. In one non-limiting arrangement, the upper cap body 402 can be over-molded on the snap cap base 403 to permanently secure the upper cap body 402 to the snap cap base 403. In some embodiments, the upper cap body 402 may be separately formed and adhered to the snap cap base 403 by, for example and without limitation, an adhesive or mechanical connection arrangement.
When the upper cap body 402 is removably attached to the snap cap base 403 and can be replaced, the upper cap body 402, after losing some or all of its corrosion protection properties, can be replaced with a new upper cap body 402 without the need for a new snap cap base 403. In some embodiments, the upper cap body 402 may be formed with a set of threads that are configured to engage a set of receiving threads in the snap cap base 403 to facilitate in the removal and replacement of the upper cap body 402 to snap cap base 403, although it is to be appreciated that other removable attachments are also contemplated.

The one or more surface features 405 can be used to enable the corrosion protection molecules that are released from the protective material to flow about the exterior surface wall 424 of the snap cap device 400 between the ends 404, 406 of the snap cap device 400. Such an arrangement is particularly advantageous when the upper cap body 402 and/or the snap cap base 403 is at least partially formed of a protective material. In one non-limiting configuration, powder, pellets, plugs, etc. of material that includes the protective material (not shown) can be placed in the hollow interior region 422 and a plug (not shown) is then inserted into the opening on the first end 404 to retain the powder, pellets, plugs, etc. of material that includes the protective material in the hollow interior region 422. The plug can optionally be formed of a porous material that allows the corrosion protection molecules that are released from the protective material to flow through the plug and then disperse about the exterior surface wall 424 of the snap cap device 400 via the one or more surface features 405. As can be appreciated, other or additional arrangement can be used to enable the corrosion protection molecules that are released from the protective material to flow out of the hollow interior region 422 (e.g., one or more holes in the upper cap body 402 that are smaller in size than the powder, pellets, plugs, etc. of material that includes the protective material, one or more holes in the first end 404 of the upper cap body 402 that are smaller in size than the powder, pellets, plugs, etc. of material that includes the protective material, etc.). When the upper cap body 402 is formed of a material that includes the protective material, the use of the one or more surface features 405 can be absent from the upper cap body 402 and/or the inclusion of powder, pellets, plugs, etc. of material that includes the protective material in the hollow interior region 422 is not required. As can be appreciated, the plug and protective material arrangement as illustrated in

A time indicator panel 430 is configured to be inserted in the recessed portion 440. Generally, the shape of the indicator panel 430 is the same or similar to the shape of the recessed portion 440. The time indicator is generally formed of a metal foil, paper, paper board, or a plastic film or sheet. As illustrated in
As discussed above, the exemplary rust and corrosion preventative snap cap devices described herein and shown in
Moreover, the associated firearms into which snap cap bodies 102, 202, 402 are configured to be inserted can generally be exposed to the environment for substantial periods of time. As such, firearms and their associated components are particularly susceptible to rust, corrosion, and tarnish. However, by including the exemplary protective snap cap devices 100, 200 and 400 described herein, rust, corrosion, and tarnish can be prevented or otherwise delayed over the life of the firearm.
In order to provide rust, corrosion, and tarnish protection, the snap cap devices 100, 200 and 400 are made with or otherwise includes a substance which inhibits volatile or vapor corrosion. The inhibiting behavior of the substance is enabled by a plurality of mechanisms. In general, the plurality of mechanisms enabling the inhibiting behavior of the substance all include the release of vapor into the air and the deposition of protective molecules on all exposed surfaces of the firearm. In one exemplary inhibiting mechanism, the corrosion protection molecules form a protective barrier against external dirt and abrasion. The molecular barrier layer inhibits electro-chemical reactions on metal surfaces by blocking the diffusion of corrosive acid gas pollutants from the environment, thereby preventing contact between these corrosive gases and the metal surfaces. In another exemplary inhibiting mechanism, the deposited molecules form a molecular layer of corrosion inhibitors that passivate the electron flow between the anodic and cathodic areas on metal surfaces and interrupt the electro-chemical corrosion process. In still another exemplary mechanism, the deposited molecules form a hydrophobic molecular layer that inhibits water from reaching the metal surface and forming the electrolyte necessary for corrosion reactions. In view of these inhibiting mechanisms, the exemplary protective snap cap devices 100, 200 and 400 advantageously shield against rust, tarnish, and corrosion.
In some particular, non-limiting embodiments, the protective material of the exemplary snap cap devices 100, 200 and 400 is provided by use of a powder, pellets, plugs, etc. that includes the protective material. In such configurations, the hollow interiors 108, 208, 422 of snap cap bodies 102, 202, 402 are filled with the vapor corrosion-inhibiting powder. The front ends 104, 204, 404 of snap cap bodies 102, 202, 402 can be configured to receive a vented plug (not shown) which at least partially seals off the hollow interiors 108, 208, 422 and prevents the vapor corrosion-inhibiting powder from spilling out of the hollow interiors.

In such configurations, the coating is applied to the exterior surface of the bodies of the snap cap devices 100, 200 and 400. In such an embodiment, the bodies of the snap cap devices 100, 200 and 400 can be made from any suitable material (e.g., plastic, metal, ceramic, composite material, wood, etc.) that is able to be coated and/or impregnated with the coating material. In such configurations, the bodies of the snap cap devices 100, 200 and 400 can be provided with or without their respective hollow interior regions 108, 208, 422. The coating that includes the protective material can be water-based, grease-based, oil-based, etc., without departing from the scope of the present disclosure. Exemplary coating products having the vapor corrosion-inhibiting substance are commercially available from Zerust®.
In still further non-limiting embodiments, the exemplary snap cap devices 100, 200 and 400 are provided with rust, corrosion, and tarnish protection by forming the bodies of the snap cap devices 100, 200 and 400 from a raw material which is infused or impregnated with or is mixed with the protective material. For example, the bodies of the snap cap devices 100, 200 and 400 can be made from a plastic or metal raw materials which have been previously impregnated with the protective material. Exemplary raw materials having the vapor corrosion inhibiting substance are commercially available from Zerust®. In some embodiments, the bodies of the snap cap devices 100, 200 and 400 are at least partially formed of a plastic material such as, but not limited to, polypropylene. The Zerust® substance may be molded with the plastic material, e.g., polypropylene, to form the material of the bodies of the snap cap devices 100, 200 and 400. In some embodiments, the Zerust® material is from about 0.5 wt. % to about 5 wt. % (and all values and ranges therebetween) of the composition of the material that is used to form the bodies of the snap cap devices 100, 200 and 400.
It should be understood from the present disclosure that the particular dimensions of the bodies of the snap cap devices 100, 200 and 400 are non-limiting.
