<Spill prevention system for vessels>
In electric liquid heating products, there is a risk of spilling hot liquid if the product is tilted or flipped by mistake. Liquids can be at or near the boiling point, so spilling can cause serious burns to the user and nearby people.

  Many proposals have been made in the art to reduce or prevent the possibility of such spills. These solutions are typically one of two types. The two types are an automatic type that can pour liquid only when the product is in a specific posture, and a manual type that can pour liquid only when the interlock is manually removed. , All depending on user operation and / or possible components. The prior art is directed to household water heater products, which are hereinafter referred to as safety electric pots.

  One problem common to electric pots is that they relieve pressure from the product and / or ventilate both during normal use (during filling, pouring, heating and cooling cycles) and during abnormal conditions such as the product overturning. There is a need to do. In general, the pouring spout of an electric pot functions as the main pressure relief and ventilation means for steam or accepts expansion and contraction. If the spout is sealed or partially sealed, usually a separate main ventilation means is provided.

  Another factor that requires ventilation in a safety electric pot is the need to equalize the pressure between the container and the atmosphere so that, for example, water can come out of the container smoothly.

  In an electric pot incorporating temperature control (such as a steam switch) mounted at a location far from the container, a steam pipe can connect between the container and the steam switch. This steam tube may provide secondary ventilation and / or pressure equalization for the product.

  In a safety electric pot, the primary or secondary ventilation means can be hampered by spill prevention features. Alternatively / additionally, when excessive water pressure occurs, the primary or secondary ventilation means can spout heated water.

  In the case of a cordless electric pot, boiling may continue for a while even after the electric pot is turned down due to the temperature difference between the heating element and water, and the pressure rises to some extent even after the power supply is cut off May continue.

  For example, Japanese Patent Application Publication No. JP-A-2008212315 discloses a manual-type safety electric kettle with a separate ventilation outlet for steam. In tests of safety electric pots marketed in Japan, and based on the content of the patent application disclosed there, if the electric pot tilts to one side, hot water erupts from the outlet for ventilation. .

  In addition, the vapor pressure can push heated water through the steam pipe to the handle and / or sub-base so that when a user attempts to lift a fallen product, And / or risk of contact with liquids. Furthermore, there is a risk that excess water will come into contact with any electrical components built into the handle and / or sub-base.

  However, if the heating vessel is completely sealed by an interlock as in GB-A-2272629, for example, there is a risk that the vapor pressure will rise inside the vessel and explode. There is sex.

  Another problem to be mentioned in connection with safety electric pots etc. is the requirement to facilitate filling and pouring.

  International Publication No. WO-A-2010 / 128334, which is a patent publication by the present applicant, discloses various means for solving this problem. Among them are mobile pendulum-configured systems on the market that provide users with spill prevention and primary ventilation while allowing users to pour out of a safe electric pot without any special operation.

  However, there is a need for safe electric pots that can be filled and poured out through the spout, and spill-proof means and primary ventilation means that do not require moving parts or user manipulation in any practical position.

  Each of the following embodiments is identified with reference to the drawings, and provides a solution to the above problems individually or in combination with other embodiments. The inventors have shown such a combination embodiment.

  It is clear that the full range of embodiments and combinations thereof are extensive. However, those skilled in the art who have read the description herein will be able to address the specific problems of individual products by combining the solutions of these embodiments within the scope of the present invention.

  Until now, safety lids have been used in portable electric water heaters such as electric pots and vacuum thermos electric pots. Further examples of products may include any product that requires some measure to prevent the heated liquid from spilling. The embodiments of the safety electric pot described below may be applied to any product for liquid heating that is prone to spilling and / or falling over. Such products include non-electrical products for containing hot liquids, such as pots and containers that can be used in microwave ovens. In this case, when heating food or liquids, there is no excessive pressure or spillage during heating or immediately after cooking, and it is safe to prevent spilling in large quantities when dropped or turned over. Can be ventilated. Embodiments of safety electric pots that do not require moving parts can be suitably applied especially to vessels that can be used for food and / or microwave ovens.

  It is known that vessels that heat liquid require an upper space or void 222 above the liquid level to accommodate turbulence and / or expansion that can occur when boiling. The liquid level 225d in the following drawings is a typical maximum liquid level in a product for liquid heating with control operated by steam, and the liquid level when schematically showing the tilt position of the product 1 is the same amount of liquid. The liquid level when spilled. Each of the spill prevention embodiments is illustrated using a liquid level 225d, but the liquid level 225d is not limited to this and may be a product having another maximum liquid level.

  In the following description, parts having similar functions in different embodiments are given the same reference numerals. The drawings are schematic and dimensions and angles cannot be determined accurately from the drawings unless otherwise specified.

  Hereinafter, for each embodiment, where appropriate, elements corresponding to those of the preceding FIG. 1 will be described using the same reference numerals.

  FIG. 9a shows a prior art safety electric kettle as described in WO-A-2010 / 128334. The lid 8 includes a lid chamber 71 and the floor thereof includes a lid lower side surface 66. The lid 8 is removably sealed between the upper end of the container 5 by a container seal 63. The lid 8 with the lid chamber 71 can be removed from the container 5 in order to allow filling or cleaning of the container 5. Alternatively or additionally, the lid 8 may be attached to the vessel body 1 by a hinge.

  The lid chamber 71 serves as a passage for the liquid from the container 5, and the liquid from the container 5 enters the lid chamber 71 through the hole 86 in the lid lower side surface 66. The liquid can then be poured out from the lid chamber 71 through the spout 7.

  In each embodiment, the vessel body has an outer wall 61 spaced from the inner wall 62, and the inner wall 62 forms the wall of the container 5. For example, as described and claimed in British Patent GB-B-2365552 and Chinese Patent CN-C-1239116, which are patents granted to the present applicant, the steam pipe 70 comprises an inner wall 62 and an outer wall. 61 through the space between.

  The liquid flow through the hole 86 is regulated by at least one mechanical flow management means 80 to prevent the liquid from escaping from the container 5 if the vessel body 1 is turned over. The mechanical flow management means may include a user operation unit 75 or may be automatic.

<Weir-type pressure relief means>
FIGS. 12w to 12z and FIGS. 13k to 13m show a first type of pressure relief and pressure equalization means that can be used for any spill prevention means. Each embodiment comprises at least two holes 92 provided on both sides of the vessel 1 at least spaced from each other. In the inclined position, at least one of the holes is above the liquid level in the vessel 1, but the liquid inside the vessel 1 is prevented from flowing out from any hole 92 below the liquid level. This permanently provides ventilation with the atmosphere from the air gap 222 without the need for moving parts, regardless of product tilt.

  As shown and described, the first pressure relief means 640 can be provided in the rear chamber 95 of the lid 8 of the safety electric pot, but other arrangements are possible.

  The rear chamber 95 is in communication with the front chamber 94, for example by holes 92d or 92e in the wall 693, so that the vapor or pressure in the rear chamber 95 is ventilated to the front chamber 94 and also to the spout 7. Also good. In other embodiments, the wall 693 may be cut such that a hole (not shown) is formed between the upper end of the wall 693 and the upper end of the vessel (not shown). The rear chamber 95 may be in direct communication with the steam pipe 70.

  The pressure relief means 640 includes two conduits 641, 642 that can function as weirs. The first conduit or path 641 communicates with the container 5 of the vessel body 1 through the hole 92 a, and the other end 645 of the conduit or path 641 communicates with the rear chamber 95 of the lid 8. The second conduit or path 642 communicates with the container 5 of the vessel body 1 through the hole 92 b, and the other end 646 of the conduit or path 642 communicates with the rear chamber 95 of the lid 8.

  The holes 92 a and 92 b are provided at positions opposite to each other in the outer peripheral direction of the vessel 1. The holes 645 and 646 are also provided at positions opposite to each other in the outer peripheral direction of the vessel. With such a configuration, the conduits or channels 641, 642 are placed opposite each other like a “snorkel” tube.

  When the vessel body 1 is in the upright position, the conduits or pathways 641, 642 ventilate without hindrance.

  As shown in FIGS. 12w and 12x, in the vessel 1 that is tilted and the spout faces upward or downward, respectively, since the hole 92a is above the liquid level 225d, water cannot flow through the hole 92a. . At the same time, water can enter the hole 92b, but the hole 646 is above the liquid level 225d, so that there is sufficient pressure “water head to raise the liquid level in the conduit or path 642 to the same height as the hole 646. There is no.

  When the vessel 1 is in the tilted position, excess vapor pressure generated in the air gap 222 enters the conduit or path 641 through the hole 92a and escapes to the rear chamber 95 through the hole 645, as indicated by arrow 634. As described above, the pressure is then vented to the atmosphere from room 94 and spout 7 or other outlet.

  On the contrary, when the vessel 1 is inclined to the opposite side, the hole 92a is below the liquid level 225d and the hole 92b is above the liquid level 225d, the ventilation means 640 functions similarly.

  Each of the conduits or paths 641, 642 is constrained by water entering the conduit or path 641, 642 when the vessel 1 is turned over and through the holes 645 or 646 as the water inside the vessel 1 settles into equilibrium. A plurality of staggered baffles 647l may be provided to help prevent ejection. The baffle can further have the function of cooling the liquid when the water is at the boiling point.

  Instead of or in addition to the plurality of baffles 647l, other methods or materials for reducing the speed of the water, other methods or materials for reducing the temperature of the water, and / or a complicated path such as a wire mesh A method or material that functions as a conduit or path 641, 642 may be provided.

  As illustrated, the inlet 92a and the inlet 92b are staggered so that they do not face in opposite directions, so that one of these inlets is compared to the other when in an inclined position. , Higher than the liquid level. This can be mitigated by placing the conduits or pathways 641, 642 on top of each other rather than side by side.

  At least a portion of the conduits or paths 641, 642 may be formed as part of a lid mold or a vessel mold with a separate lid mold (not shown).

  FIGS. 12y and 12z illustrate other embodiments in which the conduits 641, 642 are pre-formed tubes and function similarly to the embodiments described above.

  Each of the conduits or preformed tubes 641, 642 and / or the wall 693 may be arranged in a substantially straight line, as shown in FIGS. 12w and 12x, or as shown in FIGS. 12y and 12z. May be arranged in a substantially bow shape. The pre-formed tubes 641 and 642 may be arranged side by side or may be placed on top of each other.

  Each of the aforementioned pressure relief and pressure stabilization means may be provided in the vessel body and / or lid assembly.

  In each of the aforementioned pressure relief and pressure stabilization systems, water that enters the room while in the tilted position can return to the vessel 1 when the vessel 1 returns to the upright position. The inlet 92 may be provided in the lowermost part of the lid assembly.

  The embodiments described above and below are of the ventilation and / or mechanical and / or automatic spill prevention type in a plurality of different postures as described in the above-mentioned International Publication No. WO-A-2010 / 128334. It may be combined with a product for liquid heating that requires means of pouring and filling.

<Weir-type filling and pressure relief means>
FIG. 13 k shows a further embodiment of a dam-type lid 8 that allows the user to fill the vessel intuitively without opening the lid 8.

  This embodiment comprises a variation of the pressure relief means illustrated in FIGS. 12w and 12x. In this modification, the hole 92a on the front side of the pressure relief means is enlarged so that it can be used as a combination of a ventilation port and a hole for filling the vessel 1.

  The user can fill the vessel 1 through the hole 155 provided in the lid 8 when the lid is closed. The base 66 at the front part 94 of the lid 8 is tilted so that the liquid is directed towards the rear part 95. A hole 92d is provided between the front portion 94 and the rear portion 95 so that water flows toward the hole 92a through a conduit or channel 641. The hole 92c between the rear chamber 95 of the lid 8 and the vapor chamber 116 is located above the lid base 66 so that liquid does not enter the vapor chamber 116 when the vessel 1 is being filled.

  FIG. 13l is a plan view showing the embodiment shown in FIG. 13k. The hole 92a closest to the conduit or path 641 and the spout 7 is considerably larger than the conduit or path 641 and the corresponding hole 92a in the previous embodiment. The conduits or paths 641 and 642 are arranged as described above so that either one acts as a vent when the vessel 1 is tilted to one side. The holes 92a and 92b are illustrated as being circular, but the shapes can be optimized so that these holes are located closer to the outer periphery of the vessel. Furthermore, the conduits or paths 641 and 642 may further comprise a baffle 647l as already illustrated. These baffles extend upside and partially along the side of the conduit or path 641 to restrict water flow when the product is lying, but the vessel 1 is upright. It is configured not to obstruct the base of the lid 66 when filling.

  The baffle 647k illustrated in FIGS. 13m to 13mb may be provided on the container side of the holes 92a and 92b. This prevents turbulence when the vessel 1 is tilted to one side when the product is upright and / or in the filling and pouring position without interfering with the decompression means and the flow of liquid, and the holes 92a, It obstructs the liquid which invades 92b. As shown in FIG. 13 m, the baffle 647 k includes a long rib or wall 691, surrounds each of the holes 92 a and 92 b, and has a gap 692 on the side closest to the outer periphery of the container 5. Such a configuration prevents turbulent water from entering the holes 92a, 92b when the product is in an inclined position. Alternatively, the rib 691 may extend substantially toward the outer periphery of the container 5 as shown in the plan view of FIG. 13mb. This helps to prevent turbulent water from entering the holes 92a, 92b from a position higher than the levels of the holes 92a, 92b. The baffle 647k shown in FIGS. 13ma and 13mb may include an end cap 690 that can prevent turbulent water from entering the holes 92a, 92b and passing through the end of the baffle 647k. Advantageously, the hole 92f formed as part of this configuration may provide a cross-sectional area that is approximately equal to the hole 92a so that flow through the hole 92a is not constrained. Further, as shown in FIG. 13mb, the end cap 690 is combined with the rib 691, so that when the product is in an inclined position and the holes 92f and 92g are closer to the outer periphery of the container 5 than the holes 92a and 92b, together with the end 689, Additional paths that function as weirs may be constructed (indicated by arrow 634 in the figure). As shown in FIG. 13n, this configuration provides a larger margin between the liquid level 225d and the holes 92f, 92g than the previous holes 92a, 92b. In additional embodiments, other shapes of baffle 647k and end cap 690 may be employed and the present invention includes such a configuration. For example, the end 689 of the lid 690 may be parallel to the liquid level 225d in the tilted position, in which case the margin between the liquid level 225d and the holes 92f, 92g may be further improved.

  The baffle 647k may provide an opportunity to raise the liquid level 225d in the product 1, for example, in a product with a small capacity of the gap 222.

  The lid hole 155 may include a skirt 120 or other baffle means that may restrict water from exiting the lid when the vessel body is in the tilted position.

  In this embodiment, as described in International Publication No. WO-A-2010 / 128334, an actuator mechanism for pouring and opening the lid may be provided as necessary.

<Weir-type filling, pouring, and pressure relief means>
In the prior art, it has been considered counter-intuitive to ventilate mainly through the spout 7 when the safety electric pot is in an inclined position. However, the inventors have challenged such preconceptions, and such a configuration does not require moving parts and / or manipulation of the product 1 by the user, spill prevention means, pressure relief means and / or ventilation means, dispensing means. , And found to be the key to solving the problem in providing filling means.

  The innovative spill prevention system having the above features may be provided as a set of parts (part kit) or may be provided within a separate manifold. As used herein, the term manifold is used to cover both the manifold and / or a set of parts.

  Figures 13o to 13yih show a further embodiment of the present invention. In this embodiment, spill prevention means, pressure relief means, and / or ventilation means, dispensing means, and filling means are provided in the manifold type assembly 635.

  The manifold 635 includes at least one communication means 633 between the container 5 and the spout 7, and fills the container 5, dispenses from the container 5, and / or ventilates depending on the state of the product 1. .

  The communication means is indicated by arrow 633 and may take the form of a horizontal or vertical or inclined path or conduit 682 with a hole 632 located inside manifold 635. The communication means can be composed of a series of baffles 647.

  Advantageously, the manifold 635 provides spill prevention means, pressure relief means, dispensing means, and filling required in each state of the product 1 without the need for user manipulation or moving parts. Each of the means may be provided. This allows the product to be filled, emptied or ventilated through the spout 7 during normal use. Also, when the product 1 is turned over and / or lies down, the manifold can be prevented from flowing through the spout 7, allowing sufficient pressure relief and / or ventilation.

  As described above, a vessel that heats water requires an upper space or void 222 above the liquid level to accommodate the turbulent flow that occurs when the water boils. The liquid level 225d is a typical maximum liquid level for this type of water-heated product, and the liquid level when the product 1 is in the inclined position is also shown schematically when the same amount of liquid is added. Is ranked.

  As mentioned above, a key area of consideration for liquid heating products is when heating and cooling during normal use, and when excessive heat of the heating element causes excessive boiling during, for example, tilting. Relieving pressure and / or ventilating from the air gap 222 in each tilted position posture. In the description of FIGS. 13o to 13yv, pressure relief from the product and / or ventilation is referred to as first ventilation and is indicated by arrows 634 in the figure.

  FIG. 13 o is a schematic cross-sectional view of the liquid heating product 1 with a manifold 635. Manifold 635 is located in the envelope of product 1 between the heated liquid and spout 7. The manifold 635 has a hole 632 such that the first portion 678 including the plurality of baffles 647 and the second portion 679 cooperate to allow the container 5 and the spout 7 to communicate with each other inside the manifold 635. A plurality of liquid passages 682 are provided.

  The inlet hole 632 of one of the paths 682 is provided toward the front of the product 1 so that the container 5 can be almost emptied by the corresponding path 682 at the time of dispensing.

  Preferably, the hole 632 of at least one of the channels 682 may be substantially flush with the spout at the final stage of the pouring process so that the container 5 can be substantially emptied by the channel 682 during dispensing. .

  Preferably, any hole 632 of at least one of the channels 682 may be positioned lower than the spout 7 so that all of the water that enters the spout 7 during the filling process enters the container 5 during the filling process. Good.

  Reference drawings of the manifold 635i are shown in FIGS. 13q to 13tda. However, each of the described assemblies and / or structures for securing can also be applied to other manifolds, such as manifolds 635ii and 635iii described below.

  FIG. 13p is an isometric cutaway view of FIG. 13o showing the first portion 678 of the manifold 635i. Manifold 635i has a hole 632a (downward) and another hole 632b (upward). Each hole communicates with a hole 698 (towards the center) via paths 682a and 682b, respectively, whereby the container 5 communicates with the spout 7.

  Preferably, the holes 632a, 632b are oppositely disposed at the lower and upper corners of the manifold 635i, respectively, and may be formed by one or a combination of one or both of the first portion 678 and the second portion 679. As described above, the hole 698 is located substantially toward the center of the first portion 678 so as to overlap at least the lower portion of the spout 7. Baffles 647a to 647e are formed on the first portion 678 and are staggered. The baffles 647 a and 647 b are located above the hole 698, and the baffles 647 c, 647 d, and 647 e are located below the hole 698.

  During normal use, as indicated by arrow 633, container 5 is filled and emptied through path 682a. During the heating process, excess pressure and / or steam is vented along the flow path 634. Hole 632b may provide a first pressure relief and ventilation 634 to the container in the filling and dispensing process. Advantageously, the top hole 632b and the corresponding path 682b function as an additional means of emptying the container 5 when the product 1 is tilted forward and the dispensing angle is increased. Also good.

  In each embodiment, the holes 632 can be placed in an optimal location depending on the type of product. For example, it may be provided behind to improve the flow of water during dispensing and / or on the side to improve spill prevention means. In some cases, inconsistencies are considered, in which case some compromised arrangement may be selected. The positions of the holes can be different for each product. For example, the arrangement of the holes 632 in the product 1 having a flat front surface can be different from that in the round vessel 1.

  Although examples of various hole 632 arrangements and product types are shown, the invention is not limited thereto unless otherwise specified.

  FIG. 13q is an isometric exploded view of FIG. 13o showing the assembly of manifold 635i.

  Manifold 635i may include a first portion 678 and a second portion 679 that are secured together such that paths 682a and 682b are formed.

The securing means may be provided on each or any part of product 1 and / or manifold 635i. The product 1 may be provided with reciprocal ribs 401 to secure or attach the manifold inside the product 1. In a further configuration (not shown), selectively overlapping baffles and / or mutual ribs (not shown) may be formed in either or both of the first portion 678 and the second portion 679. In a configuration in which adjacent portions such as the hole 698 of the manifold 635 and the spout 7 communicate with each other, a sealing means 685 such as a gasket may be provided. Alternatively / additionally, the manifold 635 may be secured to seal.

  FIG. 13 s is an isometric exploded view of another configuration of an embodiment in which baffles 647 a through 647 e are formed on the second portion 679 and a hole 698 is provided in the first portion 678. The manifold 635i can be fixed to the product 1 by the same method as described above.

  Alternatively, as shown in FIGS. 13t to 13tda, a manifold 635i may be used as part of or in combination with other parts of the product, such as but not limited to container 5, spout 7 or lid 8, etc. As may be provided.

  As shown in FIG. 13 t, the wall of the container 5 or product 1 can function as the first portion 678. The baffles 647a to 647e may be formed on the product 1 side, or may be formed on the second portion 679 side. The second portion 679 may be fixed directly to the product 1 by any of the fixing means described above. As described and illustrated above, the mutual ribs and / or fixing means 401 may be provided on the inner wall of the product 1.

  FIG. 13 ta shows a further variant in which the manifold 635 i is provided with a complete or partial spout 677, which is located in the spout 7 of the product 1. Advantageously, such an arrangement improves liquid flow from the manifold 635i during normal use, and the spout 677 can function as a securing means and can be sealed or secured to the spout 7. .

  FIG. 13tb shows a further variant in which the entire product spout 7 is provided as part of the manifold 635i. Corresponding holes 684 can be provided inside the product 1. To assist in securing and / or sealing the assembly in this area, slotted ribs or other corresponding securing means (not shown) are provided in either or both of manifold 635i and spout hole 684.

  The configuration of FIGS. 13ta to 13tb is particularly suitable for a metal vessel in which the spout 7 of the manifold 635i is fixed to the product 1 by a known technique such as brazing.

  FIG. 13 tc shows a further configuration in which a manifold 635 i is provided as part of the assembly 685. The assembly 685 may comprise a steam path or steam chamber 640i and may be disposed between the container 5 and the lid 8, fixed and supported to the top of the container 5 or inside the top of the container 5. May be. The assembly 685 may be attached during the manufacturing process or may be provided as a separate part. In the latter case, for example, the user may be able to select whether the product is used with the manifold 635i or not. As described above, the manifold can include a spout 677.

  FIG. 13td shows a further variation in which a manifold 635i is provided inside the complete lid assembly.

  The configuration of FIG. 13 tda is particularly suitable for incorporation into known safety water heating products to replace existing mechanical and / or user spill prevention means.

  In these embodiments, a filter housing 740, for example comprising a mesh filter 652, may be provided between the spout 7 and the manifold 635 or as part of the manifold 635. In a further embodiment (not shown), a filter means may be provided in each of the holes 632.

  FIG. 13r is a schematic partial cutaway view of manifold 635i in an upright state. In some cases, this illustrated type is used to further illustrate the relationship between holes 632a, 632b, baffles 647a-647e, paths 682a, 682b, and liquid level 225 when product 1 is in the tilted position. Is incorporated by reference.

  In all embodiments of the present invention, for example, to improve fluid flow through conduits and pathways, such as the inner and outer diameter members 639 as shown in FIGS. 13r, 13xi, 13xya Means may be provided.

  In all embodiments of the present invention, an external baffle 647j is provided in front of or around the hole 632 to prevent turbulent water from entering the path 682, for example, during normal use or overturning. Also good.

  If product 1 includes a steam switch 73 or other temperature control in communication with vessel 5, product 1 includes at least one weir-type steam path or room configuration 640 in or on air gap 222. (For example, as described above with reference to FIG. 12x).

  Steam room 640 may provide second ventilation for container 5. Unless stated otherwise, the container 5 relies on the spout 7 for main ventilation.

  Figures 13u to 13w illustrate steam chambers 640i-640iii. Each may include a first portion 637 and a second portion 638.

  FIG. 13u is an exploded perspective sectional view from the rear of the product 1 showing the steam chamber 640i in the installed state (the second portion 638 has been removed for clarity).

  The first portion 637 may include an outer wall 683 and a baffle 647g. By combining with the second portion 638, a substantially U-shaped path 682c and holes 632c and 632d may be formed. For the sake of clarity, it is pointed out that the U shape referred to here refers to the flow path of the path 682 and does not refer to the cross section of the path 682c. The hole 632 c communicates directly with the gap 222 of the container 5. The hole 632d communicates directly with the steam switch 73 (not shown) or the steam pipe (not shown).

  FIGS. 13w to 13wb show cross sections of three types of modifications of the steam chamber 640, respectively. The shapes of the modified examples of FIGS. 13w to 13wb do not limit the present invention.

  FIG. 13w shows the hole 632c facing the spout. FIG. 13wa shows a hole 632c facing the back of the container. FIG. 13 wb faces the side of the container 5.

  FIG. 13 wb shows a steam chamber 640 (described later) that extends long to the vicinity of the outer periphery of the container 5.

  Each of the holes 632c is shown schematically in a baffle 647k (eg, as shown in FIG. 13m) or in FIG. 13r to prevent turbulence or prevent water entering the steam chamber 640i. A baffle 647j may be provided. Each of the paths 682c may be provided with a maze of baffles 647l to prevent liquid from flowing into the vapor chamber 640i when the product is in an inclined position.

  Preferably, the baffle 647l of the path 682c is located above the lower end surface of the vapor chamber 640i so as not to disturb the liquid flowing out of the path 682 when the product 1 is in the upright position.

  In each embodiment, as shown in FIG. 13wb, the baffle 647l may be bent or chamfered to prevent liquid from entering. Advantageously, such a configuration helps liquid to flow out of path 682c.

  In a further configuration, the first portion of the vapor chamber may be made wider so that more liquid is contained in the area.

  While FIG. 13o shows a vapor chamber configuration 640 that is substantially parallel to the liquid level 225d, in a further embodiment, the vapor chamber 640 is such that the liquid can easily return to the container 5 when the product 1 returns to the upright position. It may be inclined.

  In a further embodiment, a U-shaped path 682 c may be provided as part of other parts of the product 1 or in combination with the product 1. The other part may be, for example, the container 5 or the lid 8 (not limited to this). Alternatively, the U-shaped path 682c may be constituted by a tube or a conduit.

  The fixation of the steam chamber 640i to or with the product 1 can be similar to that described above for the manifold 635.

  In all embodiments, the steam chamber 640 and / or the manifold 635 can be formed by a single mold process, such as blow molding.

  13x, 13xb, 13xd, and 13xf are schematic front cross-sectional views of the product 1 of FIG. 13o laid down in four different directions. In FIGS. 13x and 13xd, the spout 7 is directed to the upper left, and in FIGS. 13xb and 13xf, the spout 7 is directed to the lower left.

  Product 1 includes a manifold 635i and a steam chamber 640i.

  As described above, some products do not have control that operates with steam, and in that case, the steam chamber 640i is unnecessary. However, the principle of the manifold 635i is applicable to any liquid product with or without the vapor chamber 640i.

  The top views of FIG. 13x, FIG. 13xb, FIG. 13xd, and FIG. 13xf clearly show the operational function that prevents the vapor chamber 640i from flowing liquid out of the vapor chamber 640i through the hole 632d. However, it is not easy to show the operating function of the manifold 635i in the same top view. Therefore, additionally, holes 632a, 632b, 698 of manifold 635i are shown in FIGS. 13xa, 13xc, 13xe, and 13xg corresponding to the inclined positions of FIGS. 13x, 13xb, 13xd, and 13xf, respectively. The functions of the baffles 647a to 647e and the paths 682a and 682b, respectively, are schematically shown.

  During normal use, the various paths of the steam chamber 640i and the manifold 635i are used for pouring, filling, and steam ventilation, and in the tilted position, the same path functions as a weir and first ventilation means.

  As described above, the liquid level 225d indicates the case where the water heating product is filled to the maximum liquid level.

  It should be noted that the figures are schematic and are provided only to illustrate the basic concepts of the embodiments. The concept is applicable to a wide range of product designs and shapes, and the invention is not limited to the shapes and sizes shown.

  FIGS. 13x and 13xa show the product 1 with the spout 7 facing upwards to the left.

  As shown in FIG. 13x, the hole 632c of the steam chamber 640i is below the liquid level 225d, but the free end 648 of the baffle 647g is above the liquid level 225b. Thereby, a weir is formed, and the flow of water cannot pass through the steam chamber 640i bent in a U shape. As described above, baffles 647j, 647k, and 647l may be provided to prevent turbulent flow in which water is higher than the third liquid level 225d.

  In FIG. 13x, it can be seen that the hole 632b of the manifold 635i is below the liquid level 225d, while the free end 648 of the hole 632a and the baffles 647b, 647e is above the liquid level 225d.

  FIG. 13xa schematically illustrates the function of the manifold 635i when facing the same direction as FIG. 13x. The hole 632b is below the liquid level, but the free end 648 of the baffle 647b forms a weir above the liquid level 225d and water flows out of the path 682b into the central region of the manifold 635i where the hole 698 is provided. To prevent. Such a configuration prevents liquid from flowing out of the spout.

  The hole 632a is at the opposite corner of the manifold 635, the liquid level is below the free end 648 of the baffle 647e, and liquid cannot enter the path 682a. Advantageously, with 632a on top, the path 682a can serve as the first vent for the product, as indicated by arrow 634.

  Similarly, when the water cools and contracts, the same first ventilation means 634 equalizes the pressure inside the product 1.

  13xb and 13xc show the product 1 facing left as in FIGS. 13x and 13xa, with the spout 7 facing down. In this case, the free end 648 of the steam pipe 640i is far above the liquid level 225d and has a greater safety margin than before. Conversely, manifold 635i is low and liquid level 225d is higher around manifold 635i, but water cannot flow past free end 648 of path 682b. Thus, water still cannot enter the central region of manifold 635i. Further, since the liquid level remains below the hole 632a, the path 682a still functions as the first vent for the product, as indicated by arrow 634, as described above.

  13xd to 13xg show the product 1 with the spout 7 facing to the right. In such an arrangement, the steam chamber 640i and the manifold 635i are rotated 180 degrees compared to FIGS. 13x to 13xc, and the respective portions of the steam chamber 640i and the manifold 635i have different functions (for example, the path that was a weir is the first And the first ventilation means serves as a weir).

  As shown in FIG. 13xd, the free end 648 of the wall 647f of the steam chamber 640i functions as a weir, the steam chamber hole 632c is above the liquid level 225d, and water cannot enter the hole 632c.

  In FIG. 13xd, it can also be seen that the hole 632a of the manifold 635i is below the liquid level 225d and the free end 648 of the hole 632a and the baffles 647a, 647d is above the liquid level 225d.

  FIG. 13xe schematically illustrates the function of the manifold 635i when facing the same direction as FIG. 13xd. The hole 632a is below the liquid level, but the free end 648 of the baffle 647d forms a weir above the liquid level 225d and water flows out of the path 682a into the central region of the manifold 635i where the hole 698 is provided. To prevent. Such a configuration prevents liquid from flowing out of the spout 7.

  The hole 632b is at the opposite corner of the manifold 635, the liquid level is below the free end 648 of the baffle 647e, and no liquid can enter the path 682b. With 632a above, the path 682b can function as the first vent for the product, as indicated by arrow 634.

  Similarly, when the water cools and contracts, the same first ventilation means 634 equalizes the pressure inside the product 1.

  FIGS. 13xf and 13xg show the product 1 facing in the same direction as FIGS. 13xd and 13xe, with the spout 7 facing downwards. In this case, the hole 632c of the steam pipe 640i is far above the liquid level 225d and has a greater safety margin than before. Conversely, manifold 635i is low and liquid level 225d is higher around manifold 635i, but water cannot flow past free end 648 of path 682a. Thus, water still cannot enter the central region of manifold 635i. Further, since the liquid level remains below the hole 632b, the path 682b still functions as the first vent for the product, as indicated by the arrow 634, as described above.

  In this case, the manifold 635i can function as spill prevention and first ventilation in each direction. The steam chamber 640i can function as a spill prevention means in both directions.

  Unless otherwise stated, the following embodiments are shown with respect to the directions described above with respect to FIGS. 13x, 13xb, 13xd, and 13xf.

  FIGS. 13xh and 13xi show a further configuration of the manifold 635i in which the free ends 648 of the baffles 647a to 647e are extended so that the holes 632a, 632b are located beside the manifold 635i. In this case, in the tilted position, the holes 632a, 632b are located significantly above the liquid level 225d compared to the embodiment of FIGS. 13xb and 13xc, but the size or volume of the manifold 635i is hardly increased. The embodiment of FIGS. 13xh and 13xi can increase the liquid holding capacity of the product 1 and can increase the tilt angle of the product 1 that can prevent spillage from the product 1.

  Further, FIG. 13xi shows that the fixed ends of each of the baffles 647a to 647e are provided with a series of diameter members 639 to improve flow from the product 1 during filling and dispensing. Alternatively, the surfaces of the baffles 647a to 647e may be tapered (not shown) in order to improve the flow during filling and dispensing.

  FIG. 13xj is an isometric exploded view of a further variation of manifold 635i in which only two baffles 647c, 647d are provided below hole 698 to reduce the amount of material and reduce costs.

  In the present embodiment, the central portion of the manifold 635i is narrowed for the following reason.

a. Reduce the amount of material;
b. Increasing the amount of liquid retained in container 5; and / or c. Reduce the appearance of the manifold 635e.

  FIG. 13xk is a front view of the product 1 with the manifold 635i of FIG. 13xj in a tilted position and the spout 7 facing downward, and FIG. 13xl is a schematic front view of the manifold 635i.

  Manifold 635i generally functions as described above in connection with FIGS. 13x-13xi.

  In this embodiment and each of the other embodiments, the manifold 635i may be formed wider so that the hole is positioned higher than the liquid level 225d. Such an enlargement of the manifold in a circular product can make dispensing difficult, so the configuration can be applied more favorably to products with a smaller front portion curve, as shown in FIG. 13yj.

  If the liquid level 225d of product 1 increases, a larger steam chamber 640iii can be employed, for example, to prevent water from flowing out through the hole 632d.

  In an embodiment where space reservation is of the utmost proposition, the manifold 635i may be constituted only by the upper path 632b (as shown in FIGS. 13yr and 13ys).

  Such an arrangement cannot be filled through the spout 7 and can only be used for products with removable lids.

  Because such a configuration cannot provide first ventilation regardless of direction, an additional conduit 681 (described herein with reference to FIGS. 13xu and 13xv) may be provided.

  13xm to 13xo show a schematic isometric exploded view and a cross-sectional view of manifold 635ii. Manifold 635ii includes a first portion 678, a second portion 679, and a third portion 680, respectively.

  As shown, the first portion 678 includes a hole 698, the second portion 679 includes a baffle 647h facing in a direction, and the third portion 680 includes a baffle 647i facing away from the baffle 647h. I have. Two long holes 632e, 632f may be formed between the portion 678 and the portion 679. Long path 682e communicates between holes 632e and 698.

  The hole 632 e is inside the container 5, and the hole 698 is arranged toward the opening of the spout 7.

  During normal use, path 682e provides filling and pouring means and provides a first ventilation means.

  FIGS. 13xp to 13xs are schematic front views of the product 1 with the manifold 635ii facing four different directions as described above with reference to FIGS. 13x, 13xb, 13xd and 13xf.

  In the embodiment of the manifold 635i, the paths 682a and 682b are horizontal. However, in the embodiment of the manifold 635ii, the path is vertical. In this case, the path is visible from above, so that the spill prevention feature is described. The schematic diagram 2 is not necessary.

  In FIG. 13xp and FIG. 13xq, the hole 632e is above the liquid level 225d and water cannot enter the path 682a, and the path 682e can function as a first vent as indicated by the arrow 634. The steam chamber functions as described above for FIGS. 13x and 13xb.

  In FIGS. 13xr and 13xs, the hole 632e is below the liquid level 225d, but the baffle 647h forms a weir inside the path 682e and prevents water from flowing out of the hole 698 as described above.

  However, in the direction of FIGS. 13xr and 13xs, the manifold 635ii cannot provide the first ventilation, so the steam chamber 640i is relied upon as indicated by the arrow 634.

  FIG. 13xt shows a further embodiment of a manifold 635ii in which a hole is provided at the end of the manifold, eg, as described above with reference to FIG. 13xh.

  It is preferred (but not limited to) that the first ventilation means is provided through the spout 7. FIGS. 13xu to 13xza show a modification of the manifold 635ii. In this variation, an additional conduit or path 681 is provided to ventilate (as indicated by arrow 634) from the vessel 5 through the manifold 635ii to the hole 698 when the hole 632e is below the liquid level 225d.

  A conduit or path 681 may be provided as part of the manifold 635ii. Alternatively, it can be provided as a separate part.

  Preferably, an additional conduit 681 is positioned towards the upper end of the manifold so that it is located above the liquid level 225d during normal use, providing additional dispensing means at the pouring position.

  A conduit 681 communicates from the side of the manifold 635ii opposite the hole 632e and enters the path 682f of the manifold 635ii (formed between the first portion 678 and the second portion 679). As shown, the conduit 681 may be connected to the long hole 632e and may be slightly narrowed at the connecting portion.

  Figures 13xw to 13xza show a new embodiment of manifold 635ii. Path 682e functions as described above, except that it is slightly narrowed by conduit 681.

  In the tilted position of FIGS. 13xw and 13xy, hole 632i of conduit 681 is below liquid level 225d, but the free end of baffle 647i functions as a weir to prevent water from entering the region of hole 698.

  In the tilted positions of FIGS. 13xz and 13xza, the hole 632i is above the liquid level and functions as the first ventilation as indicated by the arrow 634. In this case, the steam room 640i does not need to function as the first ventilation means.

  In a further embodiment where space reservation is a top priority, the manifold 635i (as shown in FIG. 13yr) may be configured such that the weir is located above the hole 698.

  Such an arrangement cannot be filled through the spout 7 and can only be used for products with removable lids.

  Because such a configuration cannot provide first ventilation regardless of direction, an additional conduit 681 (described herein with reference to FIGS. 13xu and 13xv) may be provided.

<Filling, pouring, pressure relief means inside the lid, weir type>
FIGS. 13y to 13yid show a further embodiment of a manifold 635iii in which filling, pouring and first ventilation are provided at the height of the lid 8 of the product 1. FIG.

  As shown in exploded view 13y, the lid assembly 8 can include an upper end 157, a steam chamber 640i, a central portion 158 that can include a hole 698 and a manifold 635iii, 632j, 632o, and holes 632k, 632l, and 632p. A bottom 66 may be provided.

  All or a part of each of the above-described parts may be molded integrally with an adjacent part.

  The air gap 222 may communicate with the steam pipe 70 through the holes 632o and 632j and the steam chamber 640i through the central portion 158. The configuration and arrangement of the steam chamber 640i has already been described and will not be repeated here.

  The manifold consists of two levels. The hole 698 is in direct communication with the spout 7 (which may include a stopper 677) and is located at the upper level. The holes 632k and 632l communicate with the container 5 and are provided at the lower level.

  The holes 632k and 632l may be disposed apart from any side surface of the hole 698 provided in the lower outer periphery of the lid assembly 8.

  The upper platform 686 may be provided below the spout, which is in communication with the holes 632k, 632l via the inclined platforms 687k, 687l, respectively.

  The paths 682k, 682l may be separate conduits, the outer periphery of the central portion 158, the top 157, the bottom 66, the holes 698, 632k, 632l, the upper platform 686, the inclined platform 687, and the baffles 647k, 647l. , 647m.

  As shown by flow path arrow 633 in FIG. 13ya, water is filled and dispensed through both paths 682k, 682l.

  The front portion of the baffle 647K can include a radial member 639 that assists in merging the water flow before dispensing and diverting the water flow during filling.

  The holes 632k, 632l may be located partly or in front of the upper platform 686 so that they are substantially hidden in FIG. 13ya.

  FIGS. 13yb to 13yc start from the hole 632l and rise up on the tilted platform 687l as shown by the arrow 633, travel around the combined free ends 648 of the baffles 647k, 647l and exit the hole 698 along the upper platform 686. The flow path of the path | route 682l is shown schematically.

  Conversely, FIGS. 13yd and 13ye as shown by arrow 633, in path 682k starting from hole 632k, going up platform 687k, going around free end 648 of baffle 647k and exiting hole 698 along upper platform 686. 1 schematically shows a water flow path.

  During normal use, the first ventilation follows the same path as arrow 633.

  13yf to 13yi illustrate manifold 635iii when the product is in the tilted position.

  In FIGS. 13yf and 13yg, the hole 632l is below the liquid level, but the combined free end 648 of the baffles 647k, 647l serves as a weir to prevent water from entering the region of the hole 698. On the other hand, the hole 832k is above the liquid level, and the path 682k functions as the first ventilation as indicated by the arrow 634.

  Conversely, in FIGS. 13yh and 13yi, hole 632k is below the liquid level, but the combined free end 648 of baffle 647k serves as a weir to prevent water from entering the region of hole 698. On the other hand, the hole 632l is above the liquid level, and the path 682l functions as the first ventilation as indicated by the arrow 634.

  In a further embodiment, a baffle 647k may be added to the underside of the lid to further improve the spill prevention means, as illustrated in FIGS. 13m, 13ma, 13mb.

  FIG. 13 yia shows a further embodiment in which the bottom 66 of the lid 8 comprises a lamp. The ramp 694 is located on the outer periphery of the lid 8, in front of the holes 632l, 632k, and is used to direct water into the holes 632l, 632k in the dispensing process. Advantageously, as the dispensing angle increases and the product 1 tilts forward, the ramp 694 directs the remaining water to the holes 632l, 632k, particularly at the end of the dispensing. Improve the flow in the process.

  In addition, the lamp 694 fills the area between the container 5 holding the hot water and the holes 6321, 632k, usually in the dispensing process, so that almost all the water is dispensed from the product 1.

  13yib and 13yic are schematic cross-sectional views of the lid 8 and the product 1. FIG. As shown in the figure, the lid 8 is sealed and fixed to the internal vessel 62 via a seal 110, and the lid 8 maintains a predetermined position so that liquid does not leak even if the product 1 is turned over. When assembled, the ramps 694 engage each other with the container 5 of the double walled vessel 1.

FIG. 13yib shows another embodiment in which the lamp 694 can be formed on the inner wall 62 of the double-walled vessel. The ramp 694 engages the bottom 66 of the lid 8 and the free end of the ramp 694 is adjacent to the opening of the holes 632l, 632k to provide the ramp 694 is not limited to a double-walled vessel, but a single-walled vessel 1 The same applies to the above.

  The embodiment has been described with reference to the holes 632 l, 632 k of the manifold 635 inside the lid 8 and the container 5. However, not limited to such a configuration, various sized and directional ramps 694 (or other configurations) improve flow and / or help ensure that the entire amount of heated liquid is dispensed. Thus, it can be provided adjacent to the hole 632 of each manifold 635 described above.

  13yie and 13yif show another configuration in which the top of the lid 8 is sealed to the vessel wall 62 and the bottom is located inside the cavity 222 of the container 5. FIG.

  In such a configuration, each or both of the holes 632k and 632l are partially or entirely formed inside the side wall of the lid 8. In this case, the holes 632k, 632l can be located closer to the outer periphery of the container 5 and can improve the means for preventing the product 1 from spilling, while the cross-section of the holes 632k, 632l is substantially the same as the cross-section of the holes 632k, 632l described above It becomes the same, and the flow rate per time of each of the paths 682k and 682l is not limited.

  In a further embodiment, the manifold 635iv can be configured with at least one inclined path 682k, 682l, for example as shown in FIGS. 13yig and 13yih, and can be provided approximately inside the container 5 and below the lid 8. Manifold 635iv is provided with holes 632k, 632l that can be formed at least partially within the sidewalls, for example, as described above. Alternatively, all of the holes 632k and 632l may be provided on the bottom or side surface of the manifold 635iv.

  In all embodiments, the relationship between the lid assembly 150, the spout 7 and the spill prevention means 635, 640 assists in preventing the liquid from boiling and popping out of the spout 7, and the height of the vessel body 1 is increased. Can be reduced.

  In each embodiment, the spill prevention means 635, 640 is configured to function without moving parts and without user manipulation. However, the present invention is not limited thereto, and the embodiments included in the scope of the present invention may be used in combination with spill prevention means including moving parts and / or user operations.

  In a further embodiment, the spill prevention means 635, 640 may be combined with or as part of the “ECO” water metering arrangement disclosed, for example, in Applicant's International Publication No. WO-A-2008 / 139173. Can be provided. In a further configuration, the manifold 635 can also function as a water metering configuration, for example, the manifold can be configured to hold a series or varying amounts of water, and the user can use this metering means to It may be possible to heat only an amount of water.

  In other embodiments, the spill prevention means 635, 640 may be disposed within the spout and assist in reducing the overall height of the vessel body 1.

  Each of the drawings illustrates a generally circular product, but the principles of manifolds, steam rooms, and ventilation weirs are equally applicable to products of other shapes.

  Through this application and earlier applications, it has been recognized that liquid spillage through the spout is a critical problem area, especially when the spout is pointing down. In this case, it is advantageous to configure the product so that the spout 7 is always stably maintained in a predictable position even when the vessel 1 is turned over, preferably not facing down.

  This can be accomplished by lowering the center of gravity so that the product 1 is always upright when the product 1 is turned over. However, storing the necessary weights makes the product look bad and difficult to use. The inventors have therefore considered to propose other solutions that fall within the normal expectations of the user's liquid product.

  FIGS. 13yj to 13yn show the product 1 having a predetermined shape that falls in a substantially horizontal direction. Each of the manifold 635li and the steam chamber 640i is configured as described above with reference to FIGS. 13x, 13ya, 13xd, and 13xe. Therefore, there is no need to further explain the spill prevention means.

  The product 1 has an elongated shape and a substantially flat side surface. When the product is turned over, the spout is positioned in a predetermined horizontal direction so that the center of gravity causes the product to lie down on one of its two flat sides. Thereby, for example, the spill prevention means such as the manifold 635i and / or the steam chamber 640i may be configured so as to correspond to a narrow range of angles or directions.

  As shown, the manifold 635i and / or the steam chamber 640li has a significant margin between the liquid level 255d and the free end 648 of the weir configuration. At this time, for example, the size of the manifold 645li and / or the steam chamber 640i can be reduced, and / or the maximum liquid level can be increased.

  FIGS. 13yn to 13yo are described above with reference to further embodiments (FIGS. 13x, 13ya, 13xd, and 13xe) where the spout is previously oriented upward when the product is flipped over. Each having a manifold 635li and a steam chamber 640i configured to function in the same manner as the above.

  As shown in FIG. 13yn, the product 1 can be configured such that the center of gravity is close to the handle portion, for example, by placing an additional weight near the handle.

  Additionally / or, as shown, the product 1 may have a teardrop shape with a generally circular front portion and a side surface extending rearward so that the spout is less likely to face downward.

  The configuration with the spout facing upward ensures that there is a significant margin between the tips of the baffles 647b, 647e in the manifold 645i and the liquid level 225d. For this reason, the manifold 635i can be made small and / or the maximum liquid level can be made high.

  As described above, if the steam chamber 640i is required, it should be configured to provide spill prevention means similar to the manifold 635i.

  Both the flow management means and pressure relief means described above may be provided as independent parts to the product manufacturer or may be incorporated into the product as part of the assembly process.

  FIG. 13 yt is a further schematic plan view of the manifold 635iii described above.

  13yu and 13yv are diagrams schematically showing a modification of FIG. 13yt. In this variant, the product 1 and / or the lid 8 has at least one protrusion 699 to accommodate the elongated manifold 635v.

  As shown in FIG. 13yu, the protruding portion 699 may be formed as an overhang so as to protrude outside the outline and outer shape of the product 1 and / or the lid 8, or as shown in FIG. 13yv. May be integrated with and mixed with the outline and outer shape of the product 1 and / or the lid 8.

  In each of FIGS. 13yu and 13yv, the holes 632k and 6321 and the free ends 648 of the baffles 647m, 647n may be located further away from the center line of the product 1. At this time, as shown by the dimension Y and the dimension X compared with the dimension W in the figure, the holes 632k, 632l and the free ends 648 of the baffles 647m, 647n are in the inclined position as compared to the embodiment of FIG. It can be located well above the liquid level.

  The embodiment of FIGS. 13yu and 13uv can be applied to any of the above-described embodiments, and can increase the liquid holding capacity of the product 1 and increase the tilt angle of the product 1 that can prevent spillage from the product. It can be made.

  Advantageously, the protrusion 699 may allow the spout 7 to be pre-configured to face upward when the product is turned over.

  In a further embodiment, although not shown, the flow management means and the pressure relief means may comprise fastening or adapting means such as screws, flanges, bayonets, etc. so that the product manufacturer can be easily attached to the vessel. In a further embodiment, flow management means and pressure relief means are provided to the product manufacturer as part of other functional parts of the vessel, such as spouts, lids, controls, handles or steam controls, for example. Also good.

  In a further embodiment, the flow management means and the pressure relief means may comprise bimetal or other actuators to operate in response to temperature.

  In further embodiments, other parts of the product, such as handles, sub-bases, gaps between the inner and outer walls, function as a “buffer” or “overflow” region that prevents liquid or vapor from overflowing the spout You can do it.

  Depending on the embodiment, the spill prevention means may not function completely until, for example, the product 1 reaches a stable state. In such an embodiment, the flow rate per hour through the spout 7 or manifold 635 is preferably limited or adjusted to an appropriate maximum flow rate during normal use, for example by adjusting the size of the holes 632. Thus, the spillage at the inclined position can be limited to the maximum flow rate until the spill prevention means functions.

  Advantageously, one or both of the spill prevention means 635 and / or 640 is used to reduce the overall height of the product compared to conventional products in which the spill prevention means is provided inside the lid 8. It may be provided inside the container 5. This reduces packaging and transportation costs.

  In at least some embodiments, the excess boiling that occurs after the product is turned off can be mitigated by using lightweight heating elements such as thick films or printed heating elements.

  Some aspects of the present invention are applicable to vessels that do not have a heating function. It is advantageous to avoid accidental spillage in common liquids as well as heated liquids.

  In all cases, the drawings are schematic, and the sizes and dimensions of ventilation, holes, inlets, outlets, etc. should be appropriately determined according to the use of the product.
