    TECHNICAL FIELD
    [001] The present invention relates to container compartments. BACKGROUND OF THE INVENTION AND PROBLEMS OF THE TECHNIQUE PRESENTED BY THE PREVIOUS TECHNIQUE
    [002] Various fluid substances (including liquids) can be packed in a rigid, flexible or foldable container (for example, bottle, bag, etc.) that have a compartment that can be opened to allow the contents to be spilled. The container with the compartment mounted on it and the contents stored therein can be characterized as a "package".
    [003] The inventors of the present invention have invented an innovative structure for a container compartment in which the compartment includes advantageous features hitherto not taught or contemplated by the prior art. SUMMARY OF THE INVENTION
    [004] According to broad aspects of a form of the invention, a compartment is provided for a container that has an inlet into the container in which the contents can be stored. The compartment includes a body that is either (A) a separate structure to be attached to the container at the intake or (b) a structure formed as a unitary portion of the container at the intake.
    [005] The body of the compartment has a platform that defines (A) a spill opening that can communicate with the intake of the container and that can make it possible to spill the contents through the spill opening and (b) at least one spill opening. ventilation that can communicate with the intake of the container and that can allow internal ventilation of an ambient atmosphere through at least one ventilation opening in said container.
    [006] The compartment body has a spout that protrudes out of the platform and extends at least partially around the spill opening.
    [007] The compartment also includes a cover to allow movement in relation to the compartment body between (A) a closed position sealed against the compartment body to prevent the flow of contents out of the compartment body and (b) a position that allows the contents to flow out of the compartment body.
    [008] The spill opening is extended with its length oriented along a line of the central geometric axis that divides the body of the compartment and the spill opening. The spill opening has a narrow arcuate end and the spill opening has a wide end that (A) is wider than the narrow end and (b) is located closest to at least one vent opening which is the narrow end. At least one ventilation opening has a maximum width as measured along a line perpendicular to the central geometric axis of the compartment body, and the maximum width of at least one ventilation opening is greater than the width of at least a portion of the spill opening while the width of the spill opening is measured along a line perpendicular to the line of the central geometric axis of the housing body. The length of the spill opening is at least three times greater than the maximum spill opening width while the maximum spill opening is measured along a line perpendicular to the line of the central geometric axis of the housing body.
    [009] The compartment can be equipped with a design that allows efficient manufacturing techniques, high quality, large volume with a reduced product rejection rate.
    [0010] The compartment can optionally be designed to allow its use with a variety of conventional or special containers that have a variety of conventional or special container finishes (for example, pressure attachment configurations, thermal connection configurations, etc. .).

    [0027] Although the present invention is susceptible to modality in many different ways, that specification and the attached drawings reveal only a few specific shapes as examples of the invention. The invention is not intended to be limited to the modalities described herein, however. The scope of the invention is pointed out in the appended claims.
    [0028] To facilitate the description, many of the figures illustrating the invention show the modalities of the compartment of the present invention in the typical orientation that the compartment would have on top of a container (not shown) when the container is oriented vertically and terms such as top, bottom, horizontal, etc. are used with reference to orientation. It will be understood, however, that the compartment of the present invention can be produced, stored, transported, used, and sold in a different orientation from the described guidelines.
    [0029] The compartment of the present invention is suitable for use with a variety of conventional or special containers, the details of which, although illustrated or fully described, would be evident to those of skill in the art and an understanding of such containers. The containers in particular, by themselves, which are illustrated and described in the present document do not form part and, therefore, are not intended to limit the present invention. It will also be understood by those of ordinary skill that innovative and non-obvious aspects of the invention are incorporated into the exemplary compartments described by themselves.
    [0030] The compartment will typically be used in a container that contains a flowing product (for example, a liquid, cream, paste, etc.) in the form of a flowing substance that can be poured from the container through the open compartment. Such a flowing substance can be sold, for example, as a food product (for example, soy sauce), a personal care product, an industrial product, a household product, or other types of products. Such substances can be for internal or external use by humans or animals, or for other uses (for example, activities involving medicine, manufacturing, commercial or domestic maintenance, construction, agriculture, etc.).
    [0031] A first embodiment of a compartment of the present invention is illustrated in the Figures in which the compartment is generally designated by reference number 20. In the first illustrated embodiment, compartment 20 is provided in the form of a separate compartment 20 which is adapted to be assembled, or otherwise attached, in a container (not shown) that would typically contain content such as a product consisting of a fluent substance. The container typically has a top portion that extends upward to define an inlet into the container and can be formed from a material suitable for the desired application (for example, molded polyethylene or polypropylene).
    [0032] It is contemplated that typically, after the compartment manufacturer produces compartment 20 (for example, by molding compartment 20 from a thermoplastic polymer), the compartment manufacturer will then transport compartment 20 to a filling factory. containers in another location where the container is either produced or otherwise supplied, and where the container is filled with a product prior to installation of compartment 20 in the filled container.
    [0033] In the illustrated modalities, the compartment is supplied as an article, component or unit manufactured separately to be detachable or non-detachable (for example, assembled or installed) in a container. In addition, it may be desirable for the compartment (or at least a portion of the base of the compartment) to be formed as a unitary part, or extension, of the container in which that unitary part or extension can also be characterized as simultaneously defining a structure of end of the container by itself.
    [0034] The preferred illustrated modalities of the compartments are initially formed separately from the container, and are adapted to be attached to the container in an inlet that provides access to the interior of the container and the contents (for example, a product contained therein) after a portion of the compartment is opened.
    [0035] The container, by itself, does not form a part of the broader aspects of the compartment of the present invention, by itself. The container can have any suitable configuration. With those forms of the compartment of the present invention where the compartment is a separately formed article, the container typically includes an upper end portion (or other suitable structure in some part of the container) that defines the mouth or inlet of the container, and such a portion or structure of the container intake has a cross-sectional configuration with which the compartment is adapted to be engaged. The main body portion of the container can have another cross-sectional configuration that differs from the cross-sectional configuration of the container at the inlet of the container. On the other hand, the container may instead be substantially uniform in shape throughout its length or height without any small portion or different cross-section.
    [0036] The container can have a wall, or walls, usually rigid that can be held by the user. The illustrated embodiments of the compartment are also suitable for use with a container that has a flexible wall or walls.
    [0037] As seen in FIGURE 8, the first embodiment of compartment 20 includes (A) a body 30 (which can be characterized as defining a peripheral wall, base, or other similar structure intended to be located on the top of the container) , (B) a cover 32 (ie, cover or cover), and (C) a hinge 36 that joins the cover 32 to the body 30. In the illustrations, the first preferred embodiment of compartment 20, the body of compartment 30, a cover 32, and hinge 36 are molded together as a unitary structure from a suitable thermoplastic material such as polypropylene or the like. Other materials can be used in place. In the illustrated embodiment, compartment 20 is initially shaped as a completely separate article which is subsequently attached to the container (not shown) after the container has been initially filled with a product.
    [0038] In alternative designs (not shown), compartment 20 could be produced from a plurality of separate parts that are aggregated together.
    [0039] As can be seen in FIGURE 11, the body of the compartment 30 includes an upper platform which can also be characterized as an inner platform 40. As can be seen in FIGURE 11, the inner platform 40 includes (1) an inner portion generally flat, and (2) a downwardly extending peripheral portion (43). As can be seen in FIGURE 11, the body 30 has an outer, lower platform 42 that extends outwardly, and surrounds the peripheral portion 43 of the inner platform 40.
    [0040] Extending downwards from the periphery of the outer platform 42 is a skirt 44 for engaging the container (not shown) when the body of the compartment 30 is mounted on the container. As can also be seen in FIGURE 3, the skirt 44 of the housing body 30 defines an internal female thread 46 for screwing a corresponding external male thread (not shown) into the container (not shown) when the body of the dispensing compartment 30 is installed in the container.
    [0041] Alternatively, the housing body skirt 44 could be provided with some other container connection means, such as a snap-fit groove or lip (not shown) to engage a groove or lip of the container neck (not shown) ), respectively. The main part of the container may have a cross-sectional shape different from the neck of the container and the skirt of the body of the compartment 44. The skirt of the body of the compartment 44 can have any suitable configuration to allow a neck of the container that protrudes upwards ( not shown) or to enable any other portion of a container received within the particular configuration of the body of the compartment 30 - even if a container does not have a neck in itself.
    [0042] Furthermore, the skirt of the compartment body 44 could instead be permanently attached to the container by means of melting and bonding by ultrasonic induction, melting and bonding, gluing, or the like, depending on the materials used for the skirt body 44 and into the container. In another alternative design (not shown), the skirt of the body of compartment 44 could be formed (for example, molded) as a unitary extension, or part, of the container.
    [0043] In the first embodiment of the illustrated invention, the receiving inlet of the container defined by the skirt of the body of the compartment 44 has a generally cylindrical configuration and includes the thread 46 that projects laterally inward. However, the body skirt of compartment 44 may have other configurations. For example, the skirt of the housing body 44 may have a prism or polygon configuration adapted to be mounted on top of a neck of the container that has a polygon configuration. Such prism or polygon configurations may not allow screw-in attachment, but other attachment means could be provided, such as an adhesive, flange arrangement and pressure fitting groove, or the like.
    [0044] As can be seen in FIGURE 11, the bottom side of the outer platform 42 is flat. However, if desired, the bottom side of the outer platform 42 could be provided with a conventional flexible "crab claw" configuration seal (not shown) that would project down from the bottom side of the outer platform 42 to seal against the top surface. void the container. Other conventional or special seal features could instead be provided to extend downwards from the underside of the outer shell of the housing body 42. Such a seal could be a conventional "V" seal, or some other conventional seal or depending on the particular application.
    [0045] As can be seen in FIGURE 10, the inner platform of the housing body 40 defines an orifice or extended spill opening 50. In the preferred embodiment illustrated in FIGURE 10, the opening 50 has a narrow arcuate end 52 'and an end wide 52 "which is wider than the narrow end 52 '. The preferred shape of the spill opening 50, although not a true ellipse, can be characterized as a narrow ovoid. In the preferred embodiment illustrated, the spill opening 50 is oriented with its length along a line of the central geometric axis A (FIGURE 11) that divides the spill opening 50 and the body of the compartment 30 (and also divides hinge 36 and cover 32). With reference to FIGURE 10, the line view 11-11 resides on the central geometric axis line.
    [0046] As can be seen in FIGURE 10, the inner platform of the compartment body 40 also defines at least one ventilation opening 60. In the preferred embodiment illustrated, there is only one ventilation opening 60, and preferably the ventilation opening 60 is circular.
    [0047] As can be seen in FIGURE 11, below the inner platform 40, the ventilation opening 60 is additionally defined by a downward extending ventilation tube 62 which is preferably cylindrical and projecting downwards from the bottom side of the inner platform 40. As can be seen in FIGURE 11, the distance at which the vent tube 62 extends below the underside of the inner platform 40 is greater than the diameter of the vent 60. When compartment 20 is closed and installed in a container (not shown), the bottom of the vent tube 62 is received into the inlet of the container and projects down approximately below the top of the container which is sealed against the underside of the outer platform of the housing body 42.
    [0048] As can be seen in FIGURE 10, the opening 60 (and its associated associated ventilation tube 62) is also preferably divided by the line of the central geometric axis of the body of compartment A. That is, the ventilation opening 60 is preferably located with its center in the line of the central geometric axis of the body of compartment A.
    [0049] Spill opening 50 and vent opening 60 are arranged so that the spill opening wide end 52 "is located closest to vent opening 60 which is the spill opening narrow end 52 '. spill opening length 50 as measured along the central geometric axis of the compartment body A is preferably at least three times the maximum spill opening width 50 while the spill opening maximum width 50 is measured along of a line perpendicular to said line of the central geometric axis of the body of compartment A.
    [0050] Additionally, in the preferred embodiment illustrated in FIGURE 10, the diameter of the vent 60 is greater than the width of at least a portion of the spill opening 50 (while the width of the spill opening 50 is measured over a straight line that is perpendicular to the line of the central geometric axis of the body of compartment A).
    [0051] Additionally, in the preferred embodiment illustrated in FIGURE 10, the vent 60 is spaced away from the nearest portion of the spill opening 50 by a distance that is less than the diameter of the vent 60.
    [0052] In the preferred embodiment illustrated in FIGURE 10, the length of the spill opening 50 is greater than its largest width while the width is measured in a straight line perpendicular to the line of the central geometric axis A. Preferably, the width of the opening spill 50 increases continuously over a major portion of the spill opening 50 length along the central axis A.
    [0053] As can be seen in FIGURE 8, a spill nozzle 70 extends at least partially around the spill opening 50. In the preferred embodiment illustrated, spill nozzle 70 extends completely around the spill opening 50 and of the vent 60. As can be seen in FIGURE 11, the spill spout 70 includes a generally vertically oriented lower portion 72 that rises above platform 40. In front of spout 70, a spill edge 76 protrudes out of the top of the lower portion 72. In the plan view, the nozzle 70 defines an approximately oval profile (FIGURE 10).
    [0054] In the preferred form of the invention, cover 32 is provided to be closed over, and to cover, an upper body part of compartment 30. Cover 32 can be moved to expose the upper body part of compartment 30 to allow spilling the contents (i.e. product) through the spill opening 50 of the container. The lid 32 is movable between (1) a closed position on the body 30 (as shown in Figures 1 to 6) which is sealed against the body of the compartment 30 to prevent the flow of the content (i.e. product) out of the body compartment 30, and (2) an open position (as shown in Figures 8 to 11). In the preferred embodiment illustrated, the lid 32 is articulated to the body of the compartment 30 by means of the hinge 36 so that it causes the lid 32 to pivot between the closed position and the open position where the lid 32 pivots on a geometric axis of the hinge that is particular to the line of the central geometric axis of the body of compartment A.
    [0055] As seen in FIGURE 11, cover 32 includes an end-end wall or cover 80 substantially surrounded by a peripheral cover flange 82. As seen in Figures 8, 11, and 12, cover flange 82 has a end surface 88 to be received, and adjacent to it, by the outer platform of the housing body 42 when the lid 32 is closed (FIGURE 1).
    [0056] In the illustrated embodiment, the hinge of compartment 36 is molded in a unitary manner with the flange of the cover 82 and with the body of the compartment 30 in a way that causes the movement of the cover 32 between the open position that exposes the nozzle of the compartment 70 , and the closed position sealed against the surface inside the nozzle of the compartment 70. The hinge 36 can be of any suitable conventional or special model. Hinge 36 can be a type of conventional pressure action as described in U.S. Patent Nos. 5,356,017, U.S. 5,642,824 or U.S. 6,321,923. The hinge could also be a hinge of the type without pressure action, which includes a handle or clamp. In still other embodiments, the hinge could be a conventional two-piece hinge, such as a clamp hinge, in which a shaft could be provided in the lid 32 while a socket for receiving that shaft could be provided in the body of the compartment 30. In some applications, the hinge (or any connection between body 30 and cover 32) can be omitted completely.
    [0057] A finger flap or thumb flap 90 (FIGURES 1, 9 and 11) can be optionally provided to project, laterally outwards, in front of the compartment cover flange 82 to assist in lifting the cover 32 to the open position.
    [0058] The lid 32 also preferably includes a hollow frame 94 (FIGURES 8, 9, and 11) for entering the nozzle 70 of the housing body 30 when the lid 32 is closed. The frame 94 extends from the end wall of the lid 80. In the preferred embodiment, the nozzle body of the compartment 70 and the frame 94 each have a configuration to enable snap-in engagement when the lid 32 is closed, as by sealing engagement of the frame 94 with the inside surface of the nozzle 70.
    [0059] The configuration of the nozzle 70 facilitates the pouring of a flowing product (i.e., content) from the container when the lid 32 is open. When the lid 32 is closed, the frame 94 acts to contain the movement of the flowing product (i.e., content) inside the nozzle 70 so as to smooth out the unwanted movement of the flowing product around the underside of the lid 32, and in such a way as to prevent the flow of the product flowing out of the nozzle body of the compartment 70 in the region between the exterior of the nozzle 70 and the flange of the lid 82.
    [0060] FIGURE 14 shows a second embodiment of a compartment of the present invention in which the second embodiment of the compartment is generally designated by reference number 20A. The second embodiment of compartment 20A is generally similar to the first embodiment of compartment 20 discussed above with reference to FIGURES (1 to 13). The second embodiment of compartment 20A shown in FIGURE 14 differs from the first embodiment of compartment 20 in that the second embodiment of compartment 20A has a longer configuration. In particular, compartment 20A includes a lid 32A which is much longer than the lid 32 of the first embodiment of compartment 20 described above with reference to FIGURES 1 to 13, but the longer lid 32A is still adapted to close and open relative to to a 30A base. This configuration of compartment 20A provides an exterior aesthetic model completely different from the closed compartment compared to the aesthetic model of the first modality of closed compartment 20 described above with reference to FIGURES (1 to 13) The internal configuration of the second modality of compartment 20A is similar , and functionally analogous to the internal configuration of the first embodiment of compartment 20 described above with reference to FIGURES 8 to 13.
    [0061] Both compartments 20 and 20A work in the same way to close a container and to be opened to allow pouring the contents of the container through the open compartment.
    [0062] The advantageous features of both compartments 20 and 20A will be described below with reference to FIGURES 1 to 13 illustrating the first embodiment of compartment 20. In particular, when compartment 20 is open (FIGURES 8 and 10), one The user can readily spill the contents from the container (not shown) through compartment 20. With reference to FIGURE 10, compartment 20 can be characterized as having a typical or normal spill orientation along the central geometric axis A of the compartment . With reference to FIGURE 10, a user would typically initially hold the container with the open compartment 20 on top of the container and with the container generally oriented vertically (in relation to the force of gravity). The user would then begin to tilt the container (with the open compartment 20 attached to it) in alignment with the line of the central geometric axis of the compartment body A so that the front of the compartment body 30 (and its edge of the compartment) spill nozzle 76) is moved downwards, while the rear of the housing body 30 and the open lid 32 would remain higher than the edge of the spout 76. A sufficiently steep inclination will cause the contents of the container to flow out through the central portion of the spill opening 50. Atmospheric ambient air can enter ventilation vent 60 to provide appropriate internal ventilation in order to assist in emptying the contents of the container through the open compartment 20.
    [0063] The arrangement and configuration of the spill opening 50 and the vent opening 60 facilitate smooth spillage. The contents of the container can be poured relatively easily with a generally consistent flow and ease of use regardless of the level of filling in the container. The vent tube of vent 62 causes the return, or internal ventilation, of ambient atmospheric air in the container and beyond the overflow content.
    [0064] The configuration of spill opening 50 and vent opening 60 also minimizes unwanted "bubbling" that can be experienced with some conventional compartments in which the flow of content out of a conventional compartment is temporarily and periodically interrupted by atmospheric air environment that flows internally.
    [0065] Slot 20 performs especially well when used to pour liquids that have viscosities similar to some types of soy sauce. In the preferred embodiment illustrated in FIGURE 10, the ventilation opening 60 is relatively small so that it can prevent or inhibit the undesirable flow of content through the ventilation openings 60, but it can still enable the internal ventilation of the atmospheric ambient air.
    [0066] The oval-shaped spill nozzle 70 that surrounds both the spill orifice 50 and the vent opening 60 provides a good flow "cut" at the edge of the spout 76 (FIGURE 11) when the container and compartment are open 20 they are tilted backwards in a vertical orientation, and the nozzle 70 causes the effective return of content within the nozzle 70 down through the pour opening 50 and into the container.
    [0067] It will be readily observed from the detailed description of the invention mentioned above and from the illustrations of it that countless other variations and modifications can be made without departing from the true spirit and scope of the innovative concepts or principles of the present invention.
