DETAILED DESCRIPTION OF DRAWINGS

[0047] In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.

[0048] It is to be understood that this invention is not limited to particular aspects of the present invention described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims. Methods recited herein may be carried out in any order of the recited events which is logically possible, as well as the recited order of events.

[0049] Where a range of values is provided herein, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits' ranges excluding either or both of those included limits are also included in the invention.

[0050] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, the methods and materials are now described.

[0051] It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely,” “only” and the like in connection with the recitation of claim elements, or use of a “negative” limitation.

[0052] When elements are referred to as being “connected” or “coupled,” the elements can be directly connected or coupled together or one or more intervening elements may also be present. In contrast, when elements are referred to as being “directly connected” or “directly coupled,” there are no intervening elements present.

[0053] Throughout this specification, like reference numbers signify the same elements throughout the description of the figures.

[0054] Referring now generally to the Figures and particularly to FIG. 1A, FIG. 1A is a cutaway front view line drawing of the invented device 100, comprising a vape pen 102 and a sleeve 104.

[0055] The vape pen 102 further comprises at least a pen top end 106, a pen base end 108, a mouthpiece 110, a casing 111, and a control 112.

[0056] The vape pen 102 is a device used for inhaling vapor, or “vaping”; this kind of device is also known as an e-cigarette, electronic cigarette, or portable inhalation system, and produces vapor for a user to inhale. The vape pen 102 is an ordinary vaping device as known in the art, and has other internal components as already known in the art that are not shown in this drawing, such as at least a power source, a vaping liquid cartridge, and a heating element. The vape pen 102 as presented in these Figures should be viewed as encompassing the internal components found in vaping devices as generally known in the art, and accordingly, perceived also as an electronic device that could easily be damaged if exposed to liquid. The invention pertains generally to the outside of the vape pen 102, so no further discussion of the internal components of the vape pen 102 is necessary here.

[0057] The sleeve 104 further comprises at least a cap 114, a sleeve top end 116, a sleeve base end 118, a top aperture 120, and a sleeve elongate body 122.

[0058] In many preferred embodiments, the sleeve 104 fully surrounds the vape pen 102, except for the sleeve base end 118, which may be left open to allow air to pass through the vape pen 102 or sealed closed by means of the cap 114. When the cap 114 is in place over the sleeve base end 118, the sleeve 104 is at least partially water-resistant, thus protecting the vape pen 102.

[0059] It should be noted that the pen top end 106 fits into the sleeve top end 116, and likewise with the pen base end 108 and the sleeve base end 118; the directions ‘top’ and ‘base’ remain consistent throughout these Figures, where ‘top’ is the end through which the user inhales vapor, either directly from the mouthpiece 110 of the vape pen 102, or through the aperture 120 of the sleeve 104 while the vape pen 102 is equipped with the sleeve 104. The sleeve top end 116 is synonymous with the “slit end” or “vapor release end” of the invented device as discussed also herein. Likewise, the ‘base’ is the end through which air is taken into the vape pen 102, allowing the vapor generated by the vape pen 102 to be inhaled. If the user tries to inhale with the cap 114 closed, the user's ability to do so may be limited because doing so would create a suction effect, like sucking the air out of any closed container. Preferred use would recommend opening the cap 114 to inhale some vapor, with air passing through the sleeve base end 118 into the pen base end 108 to replace the air the user is also inhaling out of the device 100, then closing the cap 114 again to better protect the vape pen 102 when not inhaling.

[0060] Referring now generally to the Figures and particularly to FIG. 1B, FIG. 1B is a front view line drawing of the invented device 100 of FIG. 1A, with the cap 114 in an open position, such that a volume of air 124 can pass into and through the vape pen 102 and carry a volume of vapor 126 out through the mouthpiece 110 and the aperture 120, for inhaling by a user.

[0061] Referring now generally to the Figures and particularly to FIG. 1C, FIG. 1C is a front view line drawing of the invented device 100 of FIGS. 1A & 1B, with the sleeve 104 and the vape pen 102 uncoupled and separated.

[0062] Regarding the top aperture 120 through which vapor 126 traverses the top end 116 of the sleeve 104, this aperture might in some embodiments be just a hole in the sleeve 104 through which vapor 126 can pass. The preferred form for the aperture 120 to take is a slit shape, such that a user can widen the aperture by exerting mechanical force on the sleeve top end 116 with their teeth or lips or by sucking vapor through and exerting pneumatic force, but in the absence of force exerted by a user, the aperture 120 has a resting state of being mostly closed, thus allowing better water resistance and preventing vapor from leaking out into empty air when the user isn't inhaling.

[0063] The cap 114 may further comprise some or all of these additional cap features: a cap base 114A, a cap extension 114B, a cap strap 114C, and a cap lip 114D. The cap base 114A is a flat feature that covers and seals the sleeve base end 118, such that when the cap 114 is in a closed position, the cap base 114A physically blocks moisture from getting in. The cap extension 114B is the portion of the cap 114 that extends from the cap base 114A and detachably couples the cap 114 with the sleeve base end 118. This may be by fitting the cap extension 114B into the sleeve base end 118 like a cork in a bottle, as shown; by having the cap extension 114B adapted to fit around the sleeve base end 118 as shown in FIG. 7; or by any other such means known in the art. Further, the cap 114C can optionally include the cap strap 114C, which tethers the cap 114 onto the lip or side of the sleeve 104 such that even when the cap 104 is in an open position and not coupled onto the sleeve base end 118, the cap is more difficult to misplace and is kept handy for fastening closed again. Embodiments having no cap strap 114C, wherein the cap 114 is an entirely separate piece from the sleeve 104, as presented in FIG. 6, are also possible. The cap 114 may also optionally include the cap lip 114D as labeled here, which is additional cap base 114A surface area that extends beyond the size needed just to plug up the sleeve base end 118, potentially providing more reliable sealing and also making available a tab for a user to grip when opening the cap 114. One notes that other means are known in the art for assisting the user in opening the cap 114, such as a string or cord built into the cap that can be pulled on, and further that in the absence of any such assistance, a user might still utilize fingernails, the edge of a coin, or similar to perform the method of the invention, or squeeze and manipulate the sleeve 104 if the sleeve 104 is made of an elastic material; providing of the cap lip 114D is preferred in many embodiments, but also optional. The cap strap 114C and cap 114 might be coupled at any angle relative to the vape pen 102 and sleeve 104, such as with the cap 114 ‘hanging down’ when open, opening to one side or the other, or sticking straight up. In some embodiments of the invention, the sleeve 104 may also fit onto the vape pen 102 at more than one angle, though with the caveat that a snug fit between vape pen 102 and sleeve 104 is preferred. Further, it should be noted that, while certain Figures herein present gaps of space between elements for drafting clarity to ensure these are perceived as separate elements, a snug fit between the cap 114 and the base end 118 is preferred; the cap 114 is preferably sized and shaped appropriately to fit tightly with the open base end 118 of the sleeve 104, such that the cap 114 remains in place unless a user intentionally opens the cap 114.

[0064] To uncouple and separate the vape pen 102 from the sleeve 104 and get to the position of FIG. 1B from the position of FIG. 1A, one decouples the cap extension 114B from the sleeve base end 118 and moves the cap 114 aside to leave the sleeve base end 118 open, and pulls the vape pen 102 such as by the pen base end 108 out through the open sleeve base end 118. One notes that a preferred embodiment includes the sleeve 104 being snugly fitted to the vape pen 102, and made of an elastic material; in this case, bending the sleeve 104 away from the vape pen 102 to assist with drawing the vape pen 102 through the open sleeve base end 118 may be recommended.

[0065] Referring now generally to the Figures and particularly to FIG. 2A, FIG. 2A is an isometric three-dimensional image of a first sleeve embodiment 104A (hereinafter, “first sleeve 104A”). The first sleeve 104A and subsequent sleeve embodiments in FIGS. 3A-D and FIGS. 4A-C should all be considered instances of the sleeve 104. The sleeve 104 might differ in shape for several reasons, including but not limited to compatibility with differently-shaped vape devices, improvement in functionality, or providing aesthetic variety to suit user preference. Presented also is a compass 200 showing X, Y, and Z axes, wherein the Y axis is parallel to the central axis of the vape pen 102, and the X and Z axes are orthogonal both to the Y axis and to each other; this definition is consistent wherever the compass 200 appears throughout the Figures.

[0066] Referring now generally to the Figures and particularly to FIGS. 2B through 2E, FIGS. 2B through 2E are further angles of the same first sleeve 104A of FIG. 2A. FIG. 2C is a side profile view of the first sleeve 104A. FIG. 2D is a perspective view of the first sleeve 104A that presents the sleeve base end 118 of the sleeve 104A and the cap 114.

[0067] Referring now generally to the Figures and particularly to FIG. 3A, FIG. 3A is an isometric three-dimensional image of a second sleeve embodiment 104B (hereinafter, “second sleeve 104B”). The second sleeve 104B and other sleeve embodiments in FIGS. 2A-E and FIGS. 4A-C should all be considered instances of the sleeve 104. The sleeve 104 might differ in shape for several reasons, including but not limited to compatibility with differently-shaped vape devices, improvement in functionality, or providing aesthetic variety to suit user preference.

[0068] Presented also is the compass 200 showing X, Y, and Z axes, wherein the Y axis is parallel to the central axis of the vape pen 102.

[0069] Referring now generally to the Figures and particularly to FIGS. 3B through 3D, FIGS. 3B through 3E are further angles of the same second sleeve 104B of FIG. 3A. One should note the compass 200 present in all of the images. FIG. 3B is a side profile view of the second sleeve 104B. FIG. 3C is a perspective view of the second sleeve 104B that presents the sleeve base end 118 of the second sleeve 104B and the cap 114. FIG. 3D is a further additional view of the second sleeve 104B.

[0070] Referring now generally to the Figures and particularly to FIG. 4A, FIG. 4A is an isometric three-dimensional image of a third sleeve embodiment 104C (hereinafter, “third sleeve 104C”). The third sleeve 104C and other sleeve embodiments in FIGS. 2A-E and FIGS. 3A-D should all be considered instances of the sleeve 104. The sleeve 104 might differ in shape for several reasons, including but not limited to compatibility with differently-shaped vape devices, improvement in functionality, or providing aesthetic variety to suit user preference. Presented also is the compass 200 showing X, Y, and Z axes, wherein the Y axis is parallel to the central axis of the vape pen 102. It is noted that the length of the sleeve 104, comprising the distance between the top end 116 and the base end 118, may vary between embodiments and based on the dimensions of the vape pen 102 that a given embodiment is meant to hold, where a longer model of vape pen 102 prompts a longer sleeve 104.

[0071] Referring now generally to the Figures and particularly to FIGS. 4B through 4C, FIGS. 4B through 4C are further angles of the same third sleeve 104C of FIG. 4A. One should note the compass 200 present in all of the images. FIG. 4B is a perspective view of the third sleeve 104C that presents the sleeve base end 118 of the third sleeve 104C and the cap 114. FIG. 4C is a further additional view of the third sleeve 104C.

[0072] Referring now generally to the Figures and particularly to FIG. 5A, FIG. 5A is an additional preferred embodiment of the invented device 100 that further includes a one-way valve 500 built into the vape pen 102, to allow the vapor 126 generated by the vape pen 102 out of the vape pen 102 but prevent the vapor 126 from getting back in. This is a useful feature at least because it may provide additional moisture-proofing and allow the invented device 100 to operate more efficiently by forcing the vapor 126 out of the vape pen 102 and the sleeve 104 to where the vapor 126 is accessible by the user. The one-way valve 500 may be any suitable form or variety of one-way valve as known in the art.

[0073] Referring now generally to the Figures and particularly to FIG. 5B, FIG. 5B is an additional preferred embodiment of the invented device that further includes a one-way valve 502 positioned between the mouthpiece 504 of the vape pen 102 and the aperture 116 of the sleeve 104. This valve 502 might be coupled to the inside of the sleeve 104, coupled to the outside of the vape pen 102, or even be a separate piece wedged into place between these pieces. The one-way valve 502 may be any suitable form or variety of one-way valve as known in the art.

[0074] Referring now generally to the Figures and particularly to FIG. 6, FIG. 6 is a fourth sleeve 104D wherein the cap 114 is a separate piece, with no cap strap 114D connecting the cap 114 to the rest of the sleeve 104.

[0075] Referring now generally to the Figures and particularly to FIG. 7, FIG. 7 is a fourth sleeve embodiment (hereinafter, “the fourth sleeve 104D”) with a different model of cap. In a second cap embodiment 700 (hereinafter, “the second cap 700”) the cap extension 114B doesn't fit into the interior of the sleeve 104 like a cork, but instead fits around the outside of the sleeve base end 118. As presented here, the second cap 700 may still have a cap strap 114C, if the design is adjusted accordingly.

[0076] Referring now generally to the Figures and particularly to FIG. 8, FIG. 8 presents a second model of vape pen 800 (herein, “the second vape pen 800”) having a bulging feature 802, and equipped with a fifth embodiment of the invented sleeve (hereinafter, “the fifth sleeve 104E”) that is accordingly shaped with a bulge receiver 804, such that the second vape pen 800 can fit into the fifth sleeve 104E. One notes that the process of putting the fifth sleeve 104E on and off the second vape pen 800 may be complicated by the irregular shapes, and this could be ameliorated by features such as making the sleeve out of elastic material as preferred, or maybe by providing ways to open and seal the fifth sleeve 104E at points other than the sleeve base end 118.

[0077] Referring now generally to the Figures and particularly to FIG. 9, FIG. 9 is a diagram based on the 3D model of FIGS. 2A-2E, presenting further detail regarding a thickness T1 of an elastic material 900 forming the sleeve 104, to include also the various sleeve embodiments 104A-Z presented herein. Presented in this diagram is the sleeve 104 with an interior surface 902, an exterior surface 904, the material 900 filling the space between the interior surface 902 and the exterior surface 904, a central axis A1, an inner radius R1 comprising the measurement of distance between the central axis A1 and the interior surface 902, an outer radius R2 comprising the measurement of distance between the central axis A1 and the exterior surface 904, and the thickness T1 comprising the width of the layer of material 900. It is understood that the orientation and dimensions of both R1 and R2 are extending through and perpendicular to central axis A1.

[0078] Other Figures included as diagrams herein have opted for improved drafting clarity by leaving space visible between the casing 111 of the vape pen 102 and the sleeve 104, but embodiments in which the sleeve 104 is made of elastic material 900 and fitted closely around the vape pen 102 are preferred, such that there is actually very little space allowed between the inner wall 902 and the casing 111. While embodiments having a less snug fit can be anticipated, such as embodiments sized for a broad range of compatibility with different models of vape pen 102 at the expense of a more specialized, ‘tailored’ fit, a snug fit is preferred at least for the reasons that the vape pen 102 might slip out of the sleeve 104 unexpectedly while the cap 114 is open, that the device 100 with a loose-fitting sleeve 104 might be more difficult and less comfortable to grip, or that released vapor 126 might accumulate inside of a loose sleeve 104 if given the space to occupy, instead of being made accessible to a user.

[0079] The central axis A1, as also mentioned regarding FIG. 2A, runs parallel to the Y axis as shown in the compass 200 of the Figures. The first radius R1 and second radius R2 run orthogonally to the central axis A1, and represent inner and outer radius measurements of the elongate body 122 of the sleeve 104. Specifically, R1 is the distance measurement from the central axis A1 of the sleeve 104 to the interior surface of the sleeve 104, and R2 is the distance measurement from the central axis A1 of the sleeve 104 to the exterior surface 904 of the sleeve 104. It is understood that the sleeve 104 area proximate to the top end 116, the base end 118, or both may differ in this dimension for aesthetic or functional reasons, such as by tapering, as the top end 116 is shown to have in this Figure and others, or by broadening, as the base end is shown to have in this Figure and others. In many preferred embodiments, the material 900 is of a uniform thickness T1 throughout the sleeve 104, but variations in thickness T1 of the sleeve 104 might easily occur in certain embodiments, such as at key points for added grip padding or aesthetic appearance, or for compatibly snug fit with particular models of vape pen 102 that may vary in their dimensions. Appropriate thickness T1 of material may vary depending upon the type of material 900; as mentioned previously, BPA-free silicone rubber is strongly preferred. Different types of material 900 may vary in durability or in other practicalities, which may prompt variation in sleeve 104 dimensions such as the radii R1 & R2 or the thickness T1. R1 may have a measurement of within the range of 1 millimeter to 30 centimeters, depending on the dimensions of the vape pen 102 the sleeve 104 is meant to hold. R2 may have a measurement of within the range of 1 millimeter to 30 centimeters, depending on the dimensions of the vape pen 102 the sleeve 104 is meant to hold and the preferred thickness T1 of the material 900. T1 may have a measurement within the range of 0.1 millimeter to 30 centimeters, depending upon practicality and preference. In all instances, the difference between R2 and R1 is equal to the thickness T1 of the material 900, as represented by the formula [R2−R1=T1]. For a preferred fit, the width or diameter of the vape pen 102 is approximately equal to or slightly less than two times R1.

[0080] It is further understood that the sleeve 104 is formed of the elastic material 900 having an internal resting diameter of less than two times the length of R1 when the vape pen 102 is not positioned within the sleeve 104. It is understood that the internal resting diameter of the sleeve is measured as a dimension perpendicular and extending through the central axis A1.

[0081] The sleeve 104 is thus undersized to cause the sleeve 104 to preferably press against the vape pen 102 along the majority of the length of the vape pen 102 along the central axis A1 and thereby form a tight seal that limits fluid passing within the sleeve 104 when the vape pen 102 is residing within the vape pen 102. If the value U is the measure of the undersize dimension of the sleeve in parallel with R1, then the internal resting dimension of the sleeve 104 is equal to 2 times R1 minus U or 2R1-U; the value U preferably is within the range of from R1 to 0.001 R1.

[0082] While selected embodiments have been chosen to illustrate the invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. For example, the size, shape, location or orientation of the various components can be changed as needed and/or desired. Components that are shown directly connected or contacting each other can have intermediate structures disposed between them. The functions of one element can be performed by two, and vice versa. The structures and functions of one embodiment can be adopted in another embodiment, it is not necessary for all advantages to be present in a particular embodiment at the same time. Every feature which is unique from the prior art, alone or in combination with other features, also should be considered a separate description of further inventions by the applicant, including the structural and/or functional concepts embodied by such feature(s). Thus, the foregoing descriptions of the embodiments according to the present invention are provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
