Case for lipstick, lip gloss, deodorant or cosmetics

The present invention relates to cases for lipsticks, lip glosses or makeup (or indeed other materials) and products including lipsticks, lip glosses, cosmetics, deodorants, glues and the like, and such cases.

US Patent Publication No. 2019/0328110 A1 discloses a cylindrical top cover, (i) a shoulder insertable into a lower opening of the top cover (having an open upper portion and a lower portion) and (ii) a lower portion (having an open upper portion and a closed lower portion). a cylindrical member having a cover, the upper opening portion of which is inserted around the lower outer periphery of the circumferential projection projecting outward from the center of the shoulder; a rotating body of a cylindrical member inserted into the lower cover to integrally rotate with the lower cover; a lipstick holding member for holding the lipstick at its upper portion which moves up and down while rotating integrally with the rotating body and is inserted into the center of the rotating body; a guide member provided between the rotating main body and the lipstick holding member to guide the lipstick to rise and fall when the lipstick holding member vertically moves up and down, the upper and lower portions being open and the outer circumference tapered; and a lipstick container of a cylindrical member fixed to the tapered outer circumference of the guide member, the upper and lower portions of which are open so that the upper opening is tapered to protect the lipstick inside the lipstick container.

EP Patent Publication No. 0 178 188 A2 discloses a stick holder for holding a stick of solid expendable material such as lipstick. The cover sleeve is movable axially relative to the handle where the stick is optionally held stationary to hide or expose the stick. The sleeve can be manually engaged with itself and manipulated with the required axial movement.

U.S. Patent No. 1,931,079 A discloses a lipstick holder having a longitudinal slot in the body and an open end, a paste holder that can be moved back and forth in the body, wherein the paste holder is shaped to provide a portion that engages a slot in the body and allows air to escape when filled. A cover for the open end of the body and a relatively rigid finger piece extending at an angle to the bottom of the paste holder and over a member and slot cut from the bottom of the holder leaving a hole therein to allow for a hole in the holder.

It is an object of the present invention to provide a case for an applicable material (ie a material for application to another material or object) with a simple mechanism for facilitating access to or protecting the material.

According to a first aspect, the present invention provides a case for applicable materials comprising:

an elongated outer casing comprising a base, a perimeter wall and an open top perimeter;

a material mount positioned inside the outer casing and supported by the outer casing; and

an elongated inner sleeve comprising a peripheral wall and an open upper periphery, the inner sleeve being at least partially located within the outer casing and at least partially enclosing the mount;

The mount is fixed relative to the outer casing;

The inner sleeve is configured to be slidable longitudinally between a retracted position and an extended position such that when in the retracted position the inner sleeve exposes material applicable for use (i.e., an elongated portion or any cross-sectional shape); the inner sleeve is configured to at least partially enclose (at least partially protect) the applicable material when not in use;

The inner sleeve is manipulable (eg single digit) by the user to slide the inner sleeve between a retracted position and an extended position.

It should be noted that references to 'upper' and 'lower' (or the like) in this description indicate the direction in which the applicable material expands or retracts, respectively.

The 'applicable' material from the case must be relatively viscous, so for example lipstick or lip gloss (in the form of bullets of lipstick or lip gloss), cosmetics (for example foundation in the form of a 'chubby stick'), May contain glue (in the form of a 'glue stick') or deodorant. The material is generally cylindrical, but other cross-sectional shapes are possible. In many embodiments, the material will be in the form of a stick (eg a stick of lipstick, glue stick or deodorant).

Since the mount is fixed relative to the outer casing in normal use, the material when mounted on or to the mount is also generally fixed relative to the outer casing. This does not preclude the option of removing the mount from the outer casing for replacement or repair (for example, by having the mount engage the outer casing with a snap-lock engagement), but the mount and outer casing are enclosed in an inner sleeve. are fixed relative to each other as they are extended and retracted. Indeed, it is contemplated that the mount and outer casing may be integrally manufactured in some embodiments. As a result, a cap sized to accommodate the intended applicable material may not be able to compress or crush the material if carefully placed over the material to engage the outer casing.

In one embodiment, the peripheral wall of the outer casing defines a longitudinal slot through which an externally provided protrusion (such as a tab or boss) protrudes from the peripheral wall of the inner sleeve so that the inner sleeve is positioned in a retracted position. It is manipulated by the user to slide the inner sleeve between extended positions.

In one embodiment, the case includes a cap configured to removably engage the outer casing, such as a cap removably positioned around an upper periphery of the outer casing. The coupling can be, for example, a threaded coupling or a snap lock coupling.

The base of the outer casing need not be closed, but in some embodiments is at least partially closed by one or more elements provided to support the mount within the outer casing.

In one embodiment, the peripheral wall of the outer casing is internally generally cylindrical and the peripheral wall of the inner sleeve is externally generally cylindrical (ie, has only generally circular ends). However, it will be appreciated that other cross-sectional shapes are possible, such as polygonal (eg square, triangular, rectangular), elliptical or irregular.

In one embodiment, the case is a plastic material.

In one embodiment, the mount is integral with the base of the outer casing and/or the peripheral wall of the outer casing.

In one embodiment, the case includes one or more elements (such as legs or ribs) that extend from the mount to the outer casing and support the mount.

In one embodiment, the mount includes a skirt configured to extend under the material, and the case includes one or more elements (such as legs or ribs) extending from the skirt to the outer casing and supporting the mount.

A mount may have a bottom. Thus, the material may be pushed into the mount more than desired or prevented from being supported by the floor.

In one embodiment, the mount is configured to support the material at or around the periphery of the material, at the base of the material, or at both the periphery and base of the material.

In one embodiment, the inner sleeve is configured to engage a portion of the outer casing or a portion of the mount when in the extended position to prevent movement of the inner sleeve beyond the extended position. The inner sleeve may be provided with detents or tabs that abut the outer casing or mount when in the extended position, for example.

In one embodiment, the case includes a locking mechanism (such as a catch or snap locking element) provided on the inner sleeve and the locking mechanism configured to engage the cap when the inner sleeve is in an extended position (eg, provided on the inner sleeve). in complementary recessed or snap-locking elements). Accordingly, the locking mechanism serves to prevent disengagement of such a cap and displacement of the inner sleeve from an extended position when such a cap is in use.

In one embodiment, the case includes a cap covering the applicable material and configured to removably engage the outer casing, the outer casing and the cap preferably being configured such that the inner sleeve is fully expanded and the cap and outer casing engage; A portion of the outer casing is pressed against the inner sleeve by the cap to restrain movement relative to the outer casing.

In one embodiment, the case further includes a conduit extending from the base to the bottom of the mount and is configured to facilitate filling at least the interior volume of the mount with an applicable material.

The case may include an internally molded cap (constructed to cover the applicable material and removably engage the outer casing) or a removable insert shaped to act as a mold defining the shape of a portion of the applicable material during said filling. can include Thus, when filling through the conduit is completed during manufacturing, the base and surrounding walls of the mount and cap define the final shape of the applicable material (ignoring any residual material left in the conduit). If the cap includes a removable insert, that insert is removed from the cap or before the applicable material is used, but may also serve to prevent unwanted drying of the applicable material prior to use.

In one embodiment, the outer casing defines:

one or more cut-outs in the upper periphery of the outer casing exposing portions of the inner sleeve to facilitate manipulation of the inner sleeve; and/or

One or more cutouts in the lower periphery of the outer casing that facilitate manipulation of the inner sleeve by exposing portions of the inner sleeve when the inner sleeve is retracted.

According to a second aspect, the present invention provides a product comprising:

the case according to the first aspect; and

The amount of applicable material mounted on the mount.

The material may include, for example, lipstick, lip gloss, cosmetics (foundation, etc.), deodorant or glue.

It should be noted that any of the various individual features of the embodiments described herein, including the various individual features and claims of each of the above aspects of the invention, may be combined as appropriate and desired.

1 is a schematic perspective view of a lipstick product 10 according to one embodiment of the present invention. The lipstick product 10 includes a case 12 (of plastic material) and a bullet of lipstick (not shown in this figure).

Case 12 includes a generally cylindrical elongated outer casing 14 and a cap 16; The cap 16 engages the upper periphery of the outer casing 14 with a snap lock engagement and is removed when accessing the bullet of the lipstick is desired. The outer casing 14 includes a peripheral wall 18 and a base 20 .

The peripheral wall 18 defines an elongated longitudinal slot 22 . Case 12 includes protrusions in the form of tabs 24 that are slidably movable along slots 22 between the positions shown in this figure and adjacent base 20 (not shown, on the inner sleeve). provided on the perimeter wall).

Briefly, the lipstick product 10 functions in the following manner. 2A is a schematic perspective view of the lipstick product 10 after the cap 16 has been removed. A first snap locking element 26 (comprising a flange) is evident at the upper periphery of the perimeter wall 18; Cap 16 includes a complementary snap lock element (not visible in this view) within its lower periphery configured to engage first snap lock element 26 when cap 16 is in place on outer casing 14. do.

Case 12 includes and partially houses a generally cylindrical inner sleeve 28 exposed by removal of cap 16 . As shown, the inner sleeve 28 is in an extended position. It should be noted that the tab 24 is provided on the inner sleeve 28 (in this example formed integrally with the inner sleeve 28). The bullets of the lipstick are largely obscured by the inner sleeve 28 so that the inner sleeve 28 with the inner sleeve in the extended position shown provides protection against the bullets of the lipstick.

FIG. 2B is a view similar to that of FIG. 2A with the cap 16 omitted for clarity and the inner sleeve 28 partially longitudinally retracted to expose a portion of the lipstick bullet 30 . As described in more detail below, the lipstick bullet 30 is mounted on a mount (not visible in this figure) of case 12 within outer casing 14; The mount is in turn supported by an outer casing (14).

FIG. 2c is a view similar to that of FIG. 2b but with the inner sleeve 28 in a retracted position. In this configuration, the tab 24 is at its lowest position, which is the lowest point of the inner sleeve 28 that is allowed to move (eg by means of a mount or other casing 14 described above) in the slot 22. or may be defined by the base 20. It is noted that the tab 24 may optionally include a recess in the form of a recess 32 to facilitate its manipulation, for example with a thumb or index finger.

The tab 24 or inner sleeve 28 may also optionally include a locking mechanism for engaging the cap 16 when the cap 16 is positioned on the outer casing 14 provided on the inner sleeve 28. can The locking mechanism may be, for example, a simple boss or tab (tab on inner sleeve 28 over tab 24) forming the degree of expansion or completion of first snap locking element 26 or friction fit with cap 16. (34) to resist displacement of the inner sleeve 28 and cap 16 when the latter is in an extended position.

3A is a plan view of the outer casing 14 and mount 40 of the lipstick product 10 and FIGS. 3B and 3C are perspective views. Referring to these figures, mount 40 is configured to receive a lipstick bullet 30 . Accordingly, in this embodiment the mount 40 has a generally cylindrical peripheral wall 42 and a bottom 44 (the peripheral wall 42 and the bottom 44 together define a cup). The bottom 44 prevents the lipstick bullet 30 from being pushed into the mount 40 more than desired during manufacture or use.

Mount 40 optionally includes one or more blades 46 for holding a lipstick bullet 30 projecting inwardly from peripheral wall 42 . In other embodiments, spikes, creases, or other protrusions may be used or omitted (e.g., lipstick bullet 30 is instead a friction fit between lipstick bullet 30 and surrounding wall 42). if held within the mount (40). In this example, the mount 40 includes six such blades 46 evenly distributed about the perimeter wall 42 .

The mount 40 includes a rib 48 attached to the outer casing 14 to secure the mount 40 (and thus the lipstick bullet 30) to which the outer casing 14 is fixed relative to the outer casing 14. support As can be seen most clearly in FIG. 3C , the mount 40 includes a lower skirt 50 , which is substantially a downward dependent extension of the perimeter wall 42 beyond the bottom 44 of the mount 40 . .

It should be noted that the volume of the mount 40 that accommodates the lipstick bullet 30 is defined by the peripheral wall 42 and the bottom 44 and is shallow compared to the peripheral wall 18 of the outer casing 14; ; This means that the lipstick bullet 30 is secured against the peripheral wall 18 of the outer casing 14 and the mount 40 so that the portion of the lipstick bullet 30 within the peripheral wall 42 of the mount 40 is essentially usable. because there is no The bottom 44 is thus positioned as high as possible in the mount 40 consistent with secure retention of the lipstick bullet 30 within the mount 40 during transport and use.

It will also be clear that in this embodiment the outer casing 14 (though generally cylindrical) has a recess 52 (viewed from outside the outer casing 14) in which the slot 22 is located. Recess 52, which is concave to the shape of the generally cylindrical outer casing 14, is in this example generally flat so that the slot 22 is located within a generally flat portion of the outer casing 14. (Regarding the general profile of this outer casing, recesses may also be provided in other embodiments.) Recess 52 is such that tab 24 is similarly recessed with respect to the general profile of outer casing 14, so that tab 24 and thereby reducing the risk of accidental displacement of the inner sleeve 28.

4A and 4B are schematic perspective views of a lipstick product 10 viewed obliquely from below (cap 16 omitted for clarity). FIG. 4A shows inner sleeve 28 in a retracted position, while FIG. 4B shows inner sleeve 28 in an extended position, exposing the upper portion of lipstick bullet 30 .

These figures also show the lower extremities of the ribs 48 which in this embodiment are directly connected to each other as well as the mount 40 as can be seen in the figures. The lower periphery of the inner sleeve 28 is generally cylindrical but terminates in four portions 54 defining slots therebetween for receiving the ribs 48 when the inner sleeve 28 is in the retracted position (see below). described in more detail).

5A and 5B are additional views of the outer casing 14 and mount 40. The upper register of FIG. 5A is an elevational rear view showing only the immediate upper periphery of the mount 40 . The lower register of FIG. 5A is a perspective view showing the additional portion of the mount 40 through the longitudinal slot 22 .

The upper register of FIG. 5B is also an elevational view (rotated 90 degrees relative to the upper register of FIG. 5A ) with the recess 52 of the outer casing 14 shown from the side. The lower register of Fig. 5b is a plan view similar to that of Fig. 3a, with the concave portion 52 oriented to the left as in the upper register.

6A and 6B are views of the inner sleeve 28 . In FIG. 6A the upper register is an elevation view and the lower register is a perspective view whereas in FIG. 6B the upper register is a further elevation view (rotated 90 degrees relative to the upper register of FIG. 6A) and the lower register is a plan view. In these views, portion 54 of inner sleeve 28 that defines a slot 56 for receiving rib 48 when inner sleeve 28 is in the retracted position is more clearly visible. One of these parts 54 is shorter than the other part 54: this short part 54 supports the tab 24.

7A-7D are cross-sectional views of lipstick product 10 through a vertical mid-plane. 7a shows the cap 16 in place on the outer casing 14 and inner sleeve 28 in an extended position. 7b shows the cap 16 in place on the outer casing 14 and inner sleeve 28 in an extended position. 7C shows the cap 28 removed from the outer casing 14 and inner sleeve 28 in an extended position (thus protecting the exposed lipstick bullet 30). FIG. 7D shows cap 16 removed from outer casing 14 and inner sleeve 28 in a retracted position to facilitate access to lipstick bullet 30 .

In these figures, a snap lock, such as the complementary snap lock element 60 (including a recess for receiving the first element 26) of the snap lock mechanism provided inside the lower periphery of the cap 16. The first snap locking element 26 of the mechanism is shown.

8A and 8B are perspective views of a lipstick product 70 according to another embodiment of the present invention. The view of FIG. 8B shows a side view of the lipstick product 70 opposite to that shown in FIG. 8A.

Lipstick product 70 (similar to lipstick product 10 of FIG. 1 ) includes a case 72 (of plastic material) and a bullet of lipstick (not shown in this figure). Case 72 includes a generally cylindrical elongated outer casing 74 and cap 76 . The cap 76 engages the upper periphery of the outer casing 74 with a snap lock engagement and is removed when access to the bullet of the lipstick is desired. The outer casing 74 includes a perimeter wall 78 and a base 80 .

Perimeter wall 78 defines one or more cutouts in the upper periphery of peripheral wall 78 that expose and provide user access to inner sleeve 88 . In this example, the perimeter wall 78 defines first and second cutouts 82a, 82b that expose and provide user access to the inner sleeve 88 (partially visible only in this view). ; Cutouts 82a, 82b may be used by the user as described further below, such as when extending inner sleeve 88 from a fully retracted position or retracting inner sleeve 88 from a fully extended position. 88) (e.g., Fig. 9a). In this example, the cutouts 82a and 82b are diametrically opposed to each other, but it will be appreciated that they may be spaced at other intervals if desired.

In some variations of this embodiment, the peripheral wall of the outer casing defines only one such cutout. Figure 8c is a perspective view similar to that of Figure 8b of this variant. This variant of the lipstick product 70' will look the same as the lipstick product 70 in the view of Figure 8a, but in the reverse view, since the peripheral wall 78' of the outer casing defines only one cutout, as shown in Figure 8c. appears as shown in

In another variation, the perimeter wall 78/78' defines one or more additional cutouts in the lower periphery of the perimeter wall 78.

9a, 9b and 9c are perspective views of three configurations of lipstick product 70 (cap 76 omitted). As can be seen in this figure, the perimeter wall 78 has an upper portion of a collar 92 defining cutouts 82a, 82b (or by cutout 82a in lipstick product 70'). terminate at the periphery. Collar 92 has a smaller outer diameter than the rest of the peripheral wall 78 so that collar 92 can be received by cap 76 .

Like lipstick product 10 , lipstick product 70 includes a snap lock mechanism for removably coupling cap 76 and outer casing 74 . The snap locking mechanism includes a first snap locking element formed on or by collar 92 and a second snap locking element (not visible in this view) provided on cap 76 .

In one example, the first snap locking element includes a flange. In the example of Figures 9a, 9b and 9c, the first snap locking element is one or more bosses, in this example four bosses 94 (or only two visible in this figure, one of which is only partially visible). includes If a plurality of bosses 94 are provided, they may be spaced as desired, eg uniformly, around the collar 92; In the illustrated example, bosses 94 are evenly spaced around collar 92 .

The second snap locking element provided on the cap 76 includes a flange for receiving the first snap locking element formed inside the lower periphery of the cap 76 . This second snap locking element is thus configured to engage the first snap locking element (eg boss 94 ) when the cap 76 is in place on the outer casing 74 .

FIG. 9A shows the lipstick product 70 with the inner sleeve 80 fully extended while FIG. 9B shows the inner sleeve 88 partially retracted (thus partially exposing the lipstick bullet 90) and FIG. 9c shows the inner sleeve 88 fully retracted (thus maximally exposing the lipstick bullet 90).

It should be noted that the inner sleeve 88 may be stepped in the area exposed by the cutouts 82a, 82b (or in the variation of FIG. 8C, the area exposed by the cutout 82a). Correspondingly, the outer casings 74 and 74' may be enlarged in their area in a complementary manner to accommodate the outwardly stepped portion of the inner sleeve 88. Advantageously, this configuration inhibits rotation of the inner sleeve 88 within the perimeter wall 78 (or within the perimeter wall 78'). In some embodiments, it may be desirable to step outwardly the inner sleeve 88 by an amount that extends outwardly in that region to the collar 92, so that when the inner sleeve 88 is fully extended (shown in FIG. 9A). As shown) the inner sleeve 88 and collar 92 effectively provide a continuous surface.

Additionally, the cutouts 82a, 82b in the peripheral wall 78 (likely the elongate longitudinal slot 22 in the peripheral wall 18 and the cutout 82a in the peripheral wall 78') are 78) facilitates the degree of elastic flexibility. Advantageously, cap 76 (likely cap 16 and cap 76') can optionally be configured such that its inner diameter is smaller than the outer diameter of the upper periphery of peripheral wall 78 (i.e., collar); The process of pressing the cap 76 onto the peripheral wall 78 (to be positioned as shown in FIGS. 8A and 8B ) drives the upper periphery of the peripheral wall 78 inward and contacts the inner sleeve 88 or further. make strong contact This contact has the effect of inhibiting movement of the inner sleeve 88 relative to the peripheral wall 78, which is generally undesirable.

In some embodiments, this configuration may not drive the upper periphery of the circumferential wall 78 uniformly inward about the circumference of the upper periphery of the perimeter wall 78, but the inner sleeve 88 to inhibit movement. It will be appreciated that friction (or increased friction) between the sleeve 88 and the peripheral wall 78 is not necessary to obtain the desired effect.

10A is a perspective view of the inner sleeve 88 and outer casing 74 of a detached lipstick product 70 . The partially stepped nature of the inner sleeve 88 is evident in this view. The inner sleeve 88 includes a main or upper portion 100 and a lower periphery 102 . The lower perimeter 102 has one or more enlarged portions and one or more non-enlarged portions (ie, about the diameter of the upper portion 100), the enlarged portions being complementary to the inner surface of the peripheral wall 78. It is configured to be accepted by Seth. This arrangement prevents inner sleeve 88 from rotating relative to outer casing 74 when positioned within outer casing 74 . In an example of this embodiment, lower periphery 102 has two enlarged portions 104a, 104b and two non-magnified portions (one visible at 104c), the enlarged portion being the non-magnified portion and the enlarged portion 102. alternately to form the lower periphery 102 . In this example, the magnified and unmagnified portions each span about 90 degrees of the lower periphery 102, but this can be varied as desired.

The deformed lipstick product 70 of FIG. 8C includes an enlarged portion that spans approximately 90 degrees and a non-magnified portion that spans approximately 270 degrees.

A portion of the mount 106 for the lipstick bullet 90 is also visible in this view.

10B is a further perspective view of the inner sleeve 88 and outer casing 74 of the lipstick product 70 with the inner sleeve 88 in a fully retracted position. This view more clearly shows one of the recesses 109 in the inner surface of the peripheral wall 78 for receiving the enlarged portion 104a of the lower periphery 102 of the inner sleeve 88 . In this example, the portion of the peripheral wall 78 at each of the recesses 109 is approximately half the thickness of the portion of the peripheral wall 78 elsewhere.

In this view, the perimeter wall 108 (provided with a plurality of inwardly protruding retaining blades 110) and the base 112 of the mount 106 can be seen; Perimeter wall 108 and bottom 112 together define a cup for supporting lipstick bullet 90 . As will be described further below, the bottom 112 in turn engages or is integral with the peripheral wall 78 and is capable of providing the cups 180, 112 with lipstick material through an aperture 114 defined by the bottom 112. It is supported by radial ribs defining conduits that allow filling the rear or floor.

10C is a further perspective view from below of the inner sleeve 88 and outer casing 74 of the lipstick product 70 with the inner sleeve 88 in a fully retracted position. Mount 106 includes radial ribs 116 and a central conduit 118; Radial ribs 116 fast with (or are integral with) outer casing 74 and conduit 118 and radial ribs 116 and conduit 118 . The outer casing 74 thus supports the mount 106 (and thus the lipstick bullet 90). The conduit 118 is continuous with the hole 114 in the bottom 112 so that the cups 108, 112 and the conduit 118 can be drawn into the lipstick (or other applicable) material (i.e., from below or through the base 80). can fill the back or bottom with

In an example of this manufacturing process, cups 108 and 112 are fitted with molded caps, inner sleeve 88 and outer casing 74 are assembled, and caps 70 and 70' are fitted to outer casing 74. attached The cups 108, 112 and the molded cap are filled through conduit 118, the molded cap serving to receive and mold the lipstick material.

Referring again to FIG. 10C , enlarged portions 104a, 104b and non-expanded portions 104c, 104d of the lower periphery 102 of the inner sleeve 88 are also shown. One or more of these may optionally be provided with or formed to include an inwardly extending removal restraint element configured to engage bottom 112 when inner sleeve 88 is in or near a fully extended position (e.g. eg, Figures 2a and 9a). This element thus inhibits removal of the inner sleeve 88 from the outer casing 74. Removal inhibiting elements may include, for example, undercuts, tongues or protrusions.

In the example of FIG. 10C , enlarged portions 104a and 104b provided with respective pairs of protrusions 120 and non-enlarged portions 104c and 104d with respective undercuts 122 are shown. Also, in some embodiments, enlarged portions 104a, 104b or non-magnified portions 104c, 104d (but not both) may be provided with such a mechanism.

As noted above, the conduit 118 is continuous with the aperture 114 in the bottom 112 so that the cups 108, 112 and the interior volume of the conduit 118 are in fluid communication so that the cups 108, 112 are applicable. Material may be back or bottom filled and material may be pumped, injected, etc. into cups 108, 112 along conduit 118.

11 is a perspective view of an outer casing 74 and material mount 106 of a lipstick product 70, with a mold 130 positioned on or against the peripheral wall 108 for partially shaping the applicable material. . In this arrangement, the applicable material may be back or bottom filled through conduit 118 and held and shaped by cups 108, 112 and mold 130. Mold 130 can take many suitable forms and can be made of many suitable materials, as will be appreciated by those skilled in the art. For example, the mold 130 may be a thin shell (which may be rigid or flexible and may be disposable) that fits over the peripheral wall 108 or a die or cup positioned against the peripheral wall 108 during the manufacturing process (repeated). may be suitable for use). In particular, mold 130 may also be formed by suitably shaped cap 76 (and 76' and 16 as well) therein.

12 is a cross-sectional view of mold 130 positioned relative to a funnel defined by cups 108, 112 and conduit 118 through which conduit 118 prepares a back or bottom fill 132 with material.

Thus, in this example of a manufacturing process, the outer casing 74 and material mount 106 are manufactured (whether assembled integrally or separately, such as by injection molding), and the mold 130 is attached to the peripheral wall 108. or positioned against the perimeter wall 108, the mold 130 is filled through the conduit 118. The inner sleeve 88 is placed within the outer casing 74, 74' either before or after this step and the cap 70, 70' is placed into the outer casing 74, 74' any It is attached to the outer casing 74 at points. The mold 130 is removed after the material has cured when using (eg, applying) the material as part of the manufacturing process or if the material is to set after filling. Mold 130 may also be formed by a cap and may subsequently be used as a product cap of a case.

In another example, cap 76 is internally molded to act as a mold defining a portion of applicable material 90 (in this example, the portion of applicable material 90 that extends beyond peripheral wall 108). . Cap 76 can therefore be said to replace mold 130 .

In one example, cap 76 is internally molded in this manner with an internal insert that can be removed from the interior of cap 76 after fabrication. This may be beneficial in minimizing interference between the cap 76 and the applicable material 90 during use.
