SUMMARY
It will be appreciated that there exists a need to mitigate (at least in part) at least one problem associated with the existing housings configured to receive flowable substances (also called the existing technology). After much study of, and experimentation with, the existing housings configured to receive flowable substances, an understanding (at least in part) of the problem and its solution have been identified (at least in part) and are articulated (at least in part) as follows:
To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a first major aspect) an apparatus. The apparatus includes and is not limited to (comprises) a hollow elongated housing configured to receive a flowable substance therein. A plunger assembly is configured to be movable along, at least in part, the hollow elongated housing; this is done in such a way that the plunger assembly, in use, moves, at least in part, the flowable substance along the hollow elongated housing. A plunger-moving assembly is configured to move the plunger assembly; this is done in such a way that the plunger-moving assembly, in use, urges the plunger assembly to move a predetermined amount of the flowable substance along the hollow elongated housing. In this manner, the user does not have to measure the quantity of material to be removed from the hollow elongated housing.
To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a second major aspect) an apparatus. The apparatus includes and is not limited to (comprises) a hollow elongated housing having a first open end section configured to receive a flowable substance therein. The plunger assembly is configured to be movable along a length of the hollow elongated housing; this is done in such a way that the plunger assembly, in use, moves, at least in part, the flowable substance from the hollow elongated housing and out from the first open end section. A sealing device is positioned between the plunger assembly and the hollow elongated housing; this is done in such a way that the sealing device, in use, prevents, at least in part, leakage of the flowable substance between the plunger assembly and the hollow elongated housing. A plunger-moving assembly is configured to move the plunger assembly toward the first open end section; this is done in such a way that the plunger-moving assembly, in use, urges the plunger assembly to move a predetermined amount of the flowable substance from the hollow elongated housing and out from the first open end section. In this manner, the user does not have to measure the quantity of material to be removed from the hollow elongated housing.
To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a third major aspect) an apparatus. The apparatus includes and is not limited to (comprises) a hollow elongated housing defining a cavity. The hollow elongated housing has a first open end section and a second open end section. The first open end section and the second open end section are spaced apart from each other. The cavity extends between, and is in fluid communication with, the first open end section and the second open end section. The cavity is configured to receive a flowable substance. A dispensing device is configured to be selectively attachable to the first open end section. The dispensing device is configured to be, at least in part, in fluid communication with the first open end section and the cavity (once the dispensing device is selectively attached to the first open end section). A plunger assembly is configured to be received into the cavity via the second open end section. The plunger assembly is also configured to be movable along a length of the cavity (once the plunger assembly is received into the cavity via the second open end section). The plunger assembly is also configured to be movable toward the first open end section; this is done in such a way that the plunger assembly, in use, moves, at least in part, the flowable substance, positioned in the cavity, toward, and out from, the first open end section. The plunger assembly includes a front section configured to contact (engage with) an interior surface of the first open end section to allow departure of the flowable substance from the cavity. A sealing device extends (extends radially) from the plunger assembly. The sealing device is configured to prevent, at least in part, leakage of the flowable substance positioned on the front section of the plunger assembly toward the second open end section (while the plunger assembly, in use, is moved toward the first open end section). A plunger-moving assembly is configured to be coupled to the plunger assembly. The plunger-moving assembly is configured to move the plunger assembly toward the first open end section; this is done in such a way that the plunger-moving assembly, in use, moves the plunger assembly so that a predetermined amount of the flowable substance is moved, in use, from the cavity and out from the first open end section and into the dispensing device, and out from the dispensing device.

Referring to the embodiments as depicted in FIG. 6 and FIG. 7, the screw assembly 120 is configured to threadably couple the plunger assembly 112.
Referring to the embodiment as depicted in FIG. 6, the plunger-moving assembly 118 includes a first device 134 (also called a rotation assembly) configured to be coupled to the screw assembly 120. The first device 134 is configured to rotate the screw assembly 120 in response to rotation action applied to the first device 134; this is done in such a way that the screw assembly 120, in use, urges movement of the plunger assembly 112 toward the first open end section 106.
Referring to the embodiment as depicted in FIG. 6, the plunger stem 132 (also called a stem portion) of the plunger assembly 112 is configured to extend at least one plunger diameter below the plunger portion in order to provide engagement; a technical advantage for this embodiment is that at least one plunger diameter space may be gained between the first open end section 106 and the plunger face 114 (also called a front portion) of the plunger-moving assembly 118, used for filling procedure clearances; more robust troche threshold, etc.

Referring to the embodiment as depicted in FIG. 10 (in accordance with the third major aspect), the plunger assembly 112 is configured to be received into the cavity 104 via the second open end section 108. The plunger assembly 112 is also configured to be movable along a length of the cavity 104 once the plunger assembly 112 is received into the cavity 104 via the second open end section 108. The plunger assembly 112 is also configured to be movable toward the first open end section 106; this is done in such a way that the plunger assembly 112, in use, moves, at least in part, the flowable substance, positioned in the cavity 104, toward, and out from, the first open end section 106. The plunger assembly 112 includes (for instance) a plunger face 114 configured to engage, at least in part, (or preferably fully engage) with an interior surface 107 of the first open end section 106 to allow departure of the flowable substance from the cavity 104.
Referring to the embodiment as depicted in FIG. 10 (in accordance with the third major aspect), the sealing device 116 extends from the plunger assembly 112. The sealing device 116 is configured to prevent, at least in part, leakage of the flowable substance positioned on the plunger face 114 of the plunger assembly 112 toward the second open end section 108 while the plunger assembly 112, in use, is moved toward the first open end section 106.
Referring to the embodiment as depicted in FIG. 10, the plunger assembly 112 (preferably) is configured to provide seal that mitigates, at least in part, leakage (preferably prevent leakage) between the outer surface of the screw assembly 120 (also called the spine) and the inner surface (specifically, the inner threads) positioned in the passageway 138 of the plunger assembly 112. More preferably, the sealing device 116 also includes an inner sealing device 117 that is positioned between the outer surface of the screw assembly 120 (also called the spine) and the inner surface (specifically, the inner threads) positioned in the passageway 138 of the plunger assembly 112. The inner sealing device 117 is configured to provide seal that mitigates, at least in part, leakage (preferably prevent leakage) between the outer surface of the screw assembly 120 (also called the spine) and the inner surface (specifically, the inner threads) positioned in the passageway 138 of the plunger assembly 112. For instance, a gasket may be applied to the outer surface of the plunger assembly 112, and the screw assembly 120 extends through the gasket (similar to a baby bottle nipple that gets stretched, etc.). The sealing device 116 and the inner sealing device 117 (or the gasket) may be tight so that not too much of the flowable material (product) travels through passageway 138 of the plunger assembly 112.
Referring to the embodiment as depicted in FIG. 10 (in accordance with the third major aspect), the plunger-moving assembly 118 is configured to be coupled to the plunger assembly 112. The plunger-moving assembly 118 is configured to move the plunger assembly 112 toward the first open end section 106; this is done in such a way that the plunger-moving assembly 118, in use, moves the plunger assembly 112 so that a predetermined amount of the flowable substance is moved, in use, from the cavity 104 and out from the first open end section 106 and into the dispensing device 110, and out from the dispensing device 110.
Referring to the embodiment as depicted in FIG. 10 (in accordance with an option for any major aspect), the hollow elongated housing 102 is configured to be free standing once the second open end section 108 is positioned on a horizontal working surface; this is done in such a way that the hollow elongated housing 102 extends vertically upwardly (technical advantage: reduction of the footprint of the hollow elongated housing 102).
Referring to the embodiment as depicted in FIG. 10, the plunger assembly 112 has been moved along a length of the cavity 104 (also called an internal cavity), away from the second device 136 and toward an interior surface 107 (inner face) positioned proximate to the first open end section 106. The plunger assembly 112 separates the cavity 104 into a first cavity section 104A and a second cavity section 104B.
Referring to the embodiment as depicted in FIG. 10, a selectively removable lid 146 is positioned over the first open end section 106 (above the neck portion 122). The selectively removable lid 146 is positioned to adhere to the exit portion of the neck extension 111. The selectively removable lid 146 is removable along a removal direction 406 (by a user 900).
Referring to the embodiment as depicted in FIG. 10, once the selectively removable lid 146 is removed, the dispensing device 110 is moved, along the installation direction 404, to cover the neck portion 122 (so that the flowable item contained in the hollow elongated housing 102 may exit the interior of the hollow elongated housing 102).
FIG. 11, FIG. 12 and FIG. 13 depict a bottom view (FIG. 11), a side view (FIG. 12) and a cross-sectional view (FIG. 13) of embodiments of the hollow elongated housing 102 of FIG. 1. For FIG. 13, the cross-sectional view is taken along a cross-sectional line B-B as depicted in FIG. 11.
Referring to the embodiments as depicted in FIG. 11, FIG. 12 and FIG. 13, the second device 136 has a square-shaped outer peripheral edge. The channel 142 is positioned centrally of the second device 136. The connector 140 surrounds (at least in part) the channel 142. The connector 140 extends from the second surface 152 of the second device 136. The first surface 150 and the second surface 152 are spaced apart from each other. The channel 142 extends between the first surface 150 and the second surface 152.
FIG. 14, FIG. 15 and FIG. 16 depict a bottom view (FIG. 14), a side view (FIG. 15) and a cross-sectional view (FIG. 16) of embodiments of the hollow elongated housing 102 of FIG. 1. For FIG. 16, the cross-sectional view is taken along a cross-sectional line C-C as depicted in FIG. 14.
Referring to the embodiments as depicted in FIG. 14, FIG. 15 and FIG. 16, the plunger tip 115 and the plunger face 114 are spaced apart from each other. The plunger stem 132 extends from the plunger tip 115. The plunger nipple 130 extends from the plunger face 114. The passageway 138 is formed through the plunger assembly 112, through the plunger nipple 130 and the plunger stem 132. The passageway 138 is positioned centrally of the plunger assembly 112.
FIG. 17, FIG. 18 and FIG. 19 depict perspective views of embodiments of the hollow elongated housing 102 of FIG. 1.
Referring to the embodiment as depicted in FIG. 17, the dispensing device 110 includes the neck extension 111 and an exit portal 148. The exit portal 148 is positioned at the outer edge of the neck extension 111.
Referring to the embodiment as depicted in FIG. 18, the dispensing device 110 includes the neck extension 111 and the exit portal 148. The exit portal 148 forms an elongated tapered member (portion) extending from the outer edge of the neck extension 111.
Referring to the embodiment as depicted in FIG. 19, the dispensing device 110 includes the neck extension 111 and the exit portal 148. The exit portal 148 forms an elongated slot formation positioned proximate to the outer edge of the neck extension 111.
Referring to the embodiment as depicted in FIG. 10, it will be appreciated that there may be at least two ways to fill the hollow elongated housing 102 with the flowing material. A first way is to inject the flowable material into the first open end section 106 (also called a portal. A second way if to remove the first device 134 and inject the flowable material into the bottom section (back section, rear section) of the hollow elongated housing 102, and then reinserting the first device 134 and the screw assembly 120.
Referring to the embodiment as depicted in FIG. 10, in accordance with an option, it is preferred to have the first open end section 106 and the tip of the screw assembly 120 to be spaced apart from each other. This arrangement gives an option to fill the hollow elongated housing 102 with the flowable material from (via) the first open end section 106 versus filling the hollow elongated housing 102 via from the bottom section (rear section) of the hollow elongated housing 102.
Referring to the embodiment as depicted in FIG. 10, in accordance with an option, the screw assembly 120 may be made shorter (than as depicted) so that the flowable material may be inserted via the first open end section 106 without the tip portion of the screw assembly 120 blocking the insertion of the flowable material into the interior of the hollow elongated housing 102.
Referring to the embodiment as depicted in FIG. 10, in accordance with an option, the channel 142 and the plunger stem 132 are not used, in which case the length of the screw assembly 120 may be extended so that the tip of the screw assembly 120 may be positioned or located closer to the first open end section 106, in which case the sealing device 116 may bottom out flush at the bottom of the hollow elongated housing 102. This arrangement may, advantageously, prevent the sealing device 116 from disengaging from the tip section of the screw assembly 120.
Referring to the embodiment as depicted in FIG. 10, it will be appreciated that the preferred layout and configuration of the components system is to result in zero waste (near zero waste) of flowable material (or reduced waste of flowable material).
The following is offered as further description of the embodiments, in which any one or more of any technical feature (described in the detailed description, the summary and the claims) may be combinable with any other one or more of any technical feature (described in the detailed description, the summary and the claims). It is understood that each claim in the claims section is an open ended claim unless stated otherwise. Unless otherwise specified, relational terms used in these specifications should be construed to include certain tolerances that the person skilled in the art would recognize as providing equivalent functionality. By way of example, the term perpendicular is not necessarily limited to 90.0 degrees, and may include a variation thereof that the person skilled in the art would recognize as providing equivalent functionality for the purposes described for the relevant member or element. Terms such as “about” and “substantially”, in the context of configuration, relate generally to disposition, location, or configuration that are either exact or sufficiently close to the location, disposition, or configuration of the relevant element to preserve operability of the element within the disclosure which does not materially modify the disclosure. Similarly, unless specifically made clear from its context, numerical values should be construed to include certain tolerances that the person skilled in the art would recognize as having negligible importance as they do not materially change the operability of the disclosure. It will be appreciated that the description and/or drawings identify and describe embodiments of the apparatus (either explicitly or inherently). The apparatus may include any suitable combination and/or permutation of the technical features as identified in the detailed description, as may be required and/or desired to suit a particular technical purpose and/or technical function. It will be appreciated that, where possible and suitable, any one or more of the technical features of the apparatus may be combined with any other one or more of the technical features of the apparatus (in any combination and/or permutation). It will be appreciated that persons skilled in the art would know that the technical features of each embodiment may be deployed (where possible) in other embodiments even if not expressly stated as such above. It will be appreciated that persons skilled in the art would know that other options may be possible for the configuration of the components of the apparatus to adjust to manufacturing requirements and still remain within the scope as described in at least one or more of the claims. This written description provides embodiments, including the best mode, and also enables the person skilled in the art to make and use the embodiments. The patentable scope may be defined by the claims. The written description and/or drawings may help to understand the scope of the claims. It is believed that all the crucial aspects of the disclosed subject matter have been provided in this document. It is understood, for this document, that the word “includes” is equivalent to the word “comprising” in that both words are used to signify an open-ended listing of assemblies, components, parts, etc. The term “comprising”, which is synonymous with the terms “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. Comprising (comprised of) is an “open” phrase and allows coverage of technologies that employ additional, unrecited elements. When used in a claim, the word “comprising” is the transitory verb (transitional term) that separates the preamble of the claim from the technical features of the disclosure. The foregoing has outlined the non-limiting embodiments (examples). The description is made for particular non-limiting embodiments (examples). It is understood that the non-limiting embodiments are merely illustrative as examples.
