Description

Technical Field

[0001] This invention relates to drinking containers, and more particularly to drinking containers that combine a bottle for storing a beverage and a cup for drinking the beverage. Summary of the Invention

[0002] According to the present invention, a drinking container is provided, comprising a bottle, a cup, and a lid, wherein the bottle has a base, a mouth, and a wall extending between the base and the mouth; the cup includes a base, a mouth, and a wall; a first surface of the base and an inner surface of the wall define a volume suitable for holding a drinkable beverage; and the inner surface of the wall extends from the base to a free edge defining the mouth; the lid is configured to reversibly engage with one or both of the free edge of the wall and a portion of the cup adjacent to the free edge; and the lid is configured to close the mouth; characterized in that the base and wall are configured such that the base and wall are... At least a portion of the cup is embedded in the cup volume, wherein the inner surface of the cup wall is close to said portion of the bottle wall, the cup also includes a lid storage recess, wherein the lid storage recess is defined by a second surface of the cup base and an inner surface of the recess wall, the second surface of the cup base facing away from the cup volume, the inner surface of the recess wall extending from the second surface of the cup base away from the cup volume to a free edge of the recess wall, the free edge of the recess wall defining a recess opening, the lid including a cup wall engaging device and a drinking opening, the lid being at least partially elastically deformable, and the insertion / removal of the lid into / from the lid storage recess requires at least a portion of the lid to elastically deform.

[0003] The bottle and cup walls can be a single wall defining a bottle / cup with an approximately circular cross-section (in a plane generally perpendicular to the central axis of the bottle / cup, extending from the center of the base to the center of the mouth). Alternatively, the bottle and cup walls can comprise multiple flat or curved elements combined to define the bottle / cup walls. The bottle / cup walls can be single-layered or double-layered, with gaps between the layers. These gaps can be used for insulation purposes and filled with a suitable insulator or vacuum.

[0004] The drinking container of the present invention is advantageous because it generally includes all the elements necessary for a user to store and drink a beverage (e.g., a hot or cold drink). This includes a lid for the cup from which the beverage is drunk. The lid helps prevent spills and helps to keep hot drinks hot or cold drinks cold, respectively.

[0005] Another advantage of the drinking container of the present invention is that the lid is stored in the lid storage recess when not in use. This helps to prevent the lid from being lost.

[0006] The configuration of the lid and the recessed storage compartment is advantageous because once the lid is in the recess, the elastic deformation of the lid required to place it in the recess is at least partially eliminated, and this elimination of elastic deformation causes the lid to remain in the recess. When it is desired to remove the lid from the recess, the user deforms the lid by direct force or by pulling on the wall of the recess, allowing the lid to be removed. This is a simple mechanism requiring fewer parts and is less likely to fail. This is especially true if the lid is formed wholly or partially from a suitable elastically deformable material such as food-grade silicone rubber.

[0007] In some embodiments, the cup lid is fully elastically deformable. This has the advantage that there is no interface between the elastically deformable and non-elastically deformable portions of the cup lid. Such interfaces may fail due to the different material properties on either side.

[0008] In some embodiments, the cup further includes a base cap configured to reversibly close the opening of a cap storage recess. In some embodiments, placing the cap into the cap storage recess includes the steps of: engaging the cup cap with one or more cap engaging devices coupled to or attached to the base cap, retaining the base cap, and inserting the cup cap into the cap storage recess. In some embodiments, the base cap may engage with the recess wall via an engaging device. In some examples, the engaging device may be a bayonet-type engaging device. In other examples, it may be a threaded connection.

[0009] In some embodiments, the recess wall includes at least one retaining protrusion, wherein each retaining protrusion extends from a free edge of the recess wall or from a portion of the inner surface of the recess wall, and each retaining protrusion extends over or into a portion of the recess opening into the cap storage recess. When the cap is placed into or removed from the storage recess, the cap is elastically deformable to pass over or over the retaining protrusion or each retaining protrusion. When the cap is in the storage recess, it will seek to return to its normal shape (the shape of the cap when not subjected to the deforming force that would cause elastic deformation), and is secured behind each retaining protrusion when viewed from outside the storage recess.

[0010] An example of a suitable retaining protrusion is a ridge, which extends longitudinally along a free edge generally parallel to the recess wall. In some embodiments, the ridge extends along the entire length or substantially the entire length of the free edge of the recess wall. In other embodiments, there are more than one ridge, which are generally parallel to the free edge of the recess wall, all of which are generally in the same plane and distributed along the free edge.

[0011] In some embodiments, at least one retaining protrusion is a retaining plate extending between a portion of the free edge of the recess wall. In some embodiments, the free edge of the recess wall defines a generally circular recess opening, and the retaining plate is a generally circular segment.

[0012] In some embodiments, there may be two or more retaining protrusions. These retaining protrusions may have substantially the same configuration as each other, or at least two retaining protrusions may have different configurations, for example, there may be two retaining protrusions, one being the ridge as described above, and the other being the retaining plate as described above.

[0013] In some embodiments, the cup wall engagement device of the cup lid is elastically deformable, and the elastic deformation of the cup wall engagement device is required to insert the cup lid into / remove the cup lid from the cup lid storage recess.

[0014] In some embodiments, the lid further includes a deformation zone, the cup wall engagement means of the lid extending around the outer periphery of the lid, the deformation zone being approximately parallel to the cup wall engagement means, and requiring elastic deformation of the deformation zone to insert the lid into / remove the lid from the lid storage recess. The deformation zone is a region configured and adapted to be more elastically deformable than at least a portion of the rest of the lid.

[0015] In some embodiments of the present invention, the cup lid further includes a first lid element and a second lid element. The first lid element includes a cup wall engaging device, a drinking orifice, and a rotary joint element. The second lid element includes a drinking orifice sealing element and a rotary joint element. The rotary joint elements of the first and second lid elements are combined to form a rotary joint between the first and second lid elements. Rotation of the second lid element relative to the first lid element allows the second lid element to move between a closed position where the drinking orifice sealing element closes the drinking orifice and an open position where the drinking orifice sealing element does not close the drinking orifice.

[0016] The rotary joint can be any known joint construction that allows desired relative movement between the first and second lid elements. This relative movement allows the second element to move on a surface of the first element away from the cup volume when the lid is attached to the free edge of the cup wall. In some embodiments, the rotary joint has the form of a 360° hinge, wherein the rotary joint element of one of the first and second lid elements includes a hinge pin, while the other rotary joint element has a recess for the hinge pin. In some embodiments, at least a portion of the second lid element is elastically deformable, and the deformation of the second lid element in the closed position allows the drinking spout sealing element to close the drinking spout. In some embodiments, the cup rim is generally planar, and when the cup wall engagement device of the lid engages with the cup wall, the angle of the axis around which the second lid element rotates relative to the first lid element with respect to the perpendicular line to the plane of the cup rim falls within the range of about 10 degrees.

[0017] According to a second aspect of the invention, a drinking container is provided comprising a cup and a lid, wherein the cup includes a cup base, a cup mouth, and a cup wall, a first surface of the cup base and an inner surface of the cup wall defining a cup volume, the cup volume being suitable for holding a drinkable beverage, and the inner surface of the cup wall extending from the cup base to a free edge defining the cup mouth of the cup wall, the lid including a cup wall engaging means and a drinking orifice, the lid being at least partially elastically deformable, the lid being configured to reversibly engage with one or both of a free edge of the cup wall and a portion of the cup wall adjacent to the free edge, and the lid being configured to close the cup mouth, characterized in that the lid further includes a first lid element and a second lid element, the first lid element including a cup wall engaging means, a drinking orifice, and a rotary joint element, the second lid element including a drinking orifice closing element and a rotary joint element, the rotary joint elements of the first and second lid elements being coupled to form a rotary joint between the first and second lid elements, and rotation of the second lid element relative to the first lid element allowing the second lid element to move between a closed position where the drinking orifice closing element can close the drinking orifice and an open position where the drinking orifice closing element cannot close the drinking orifice.

[0018] The advantages of the cup of the first aspect of the present invention are the same as those of the cup of the second aspect of the present invention. Various embodiments of the cup lid described in conjunction with the first aspect of the present invention are applicable to the cup of the second aspect of the present invention. In some embodiments, at least a portion of the second lid element is elastically deformable, and the deformation of the second lid element in its closed position allows the drinking opening sealing element to close the drinking opening. In some embodiments, the rim of the cup is generally planar, and when the cup wall engaging device of the cup lid engages with the cup wall, the angle of the axis around which the second lid element rotates relative to the first lid element relative to the perpendicular line of the rim plane falls within approximately 10 degrees.

[0019] In some embodiments, the cup further includes a lid storage recess, wherein the lid storage recess is defined by a second surface of the cup base and an inner surface of the recess wall, the second surface of the cup base facing away from the cup volume, the inner surface of the recess wall extending from the second surface of the cup base away from the cup volume to a free edge of the recess wall, the free edge of the recess wall defining a recess opening, and inserting / removing the lid into / from the lid storage recess requires at least a portion of the lid to elastically deform.

[0020] In some embodiments, the cup wall engagement device of the lid is elastically deformable, and inserting / removing the lid into / from the lid storage recess requires elastic deformation of the cup wall engagement device. In some embodiments, the lid further includes a deformation region, the cup wall engagement device of the lid extending around the outer periphery of the lid, the deformation region being generally parallel to the cup wall engagement device, and inserting / removing the lid into / from the lid storage recess requires elastic deformation of the deformation region.

[0021] In some embodiments of this aspect of the invention, the cup also includes a base cap as described in conjunction with the first aspect of the invention.

[0022] According to another aspect of the invention, a drinking container is provided comprising a bottle, a cap, and a cup, wherein the bottle comprises a bottle base, a bottle neck, and one or more bottle walls, the edge of which, or each of the bottle walls, is joined to the bottle base, the bottle wall or each of the bottle walls extends between the bottle base and the bottle neck, one or more edges of the bottle wall or each of the bottle walls remotely distant from the bottle base define the bottle neck, and the bottle wall or each of the bottle walls has an inner surface and an outer surface, the inner surface defining a volume within the bottle for storing beverage, the cap being configured to reversibly close the bottle neck, and the cup comprises a cup base, a cup neck, and one or more cup walls, the cup wall or each of the cup walls being joined to the cup base, the cup wall or each of the cup walls extending between the cup base and the cup neck, the edge of the cup wall or each of the cup walls remotely distant from the cup base defining or adjacent to the cup neck, and the cup wall or each of the cup walls having... The cup has an inner surface and an outer surface, the inner surface defining a volume within the cup that can hold a beverage. The cup is characterized by comprising a lower portion and an upper portion, the lower portion extending from a base to a first intermediate position located between the base and the neck, and the upper portion extending from a second intermediate position to a second position, wherein the second intermediate position is located between the first intermediate position and the second position, and the second position is located between the second intermediate position and the neck. The cup is constructed and sized such that it can reversibly cover at least a portion of the outer surface of the base and the lower portion of the cup, wherein the inner surface of the cup wall or each cup wall contacts or is adjacent to the outer surface of the lower portion of the cup, and the dimensions of the outer surface of the cup wall or each cup wall adjacent to or at the neck are substantially the same as the dimensions of the outer surface of the upper portion of the cup at or adjacent to the second intermediate position.

[0023] In some embodiments, the bottle base is circular or nearly circular and has a single bottle wall extending from the bottle base to the bottle mouth.

[0024] In some embodiments, the bottle base is non-circular; for example, it may be dodecagonal and have twelve faces surrounding the edge of the bottle base. In such embodiments, the number of bottle sidewalls is the same as the number of faces on the edge of the bottle base.

[0025] In some embodiments, the bottle wall is formed from a single component and may include bends, elbows, or folds to give the bottle a desired shape. In other embodiments, the bottle may be formed from two or more components suitably joined together. These components may include bends, elbows, or folds to give the bottle a desired shape.

[0026] In some embodiments, the cross-section of the bottle in a plane perpendicular to the bottle's actual axis has approximately the same shape along the length of the central axis. The dimensions of the cross-section may be constant or vary along the length of the central axis.

[0027] In some embodiments, the cross-sections of the bottle in a plane perpendicular to the bottle's central axis do not have substantially the same shape along the length of the axis.

[0028] The bottle base may be formed as part of the same component as the bottle wall or each bottle wall, and thus be continuously bonded to the bottle wall or each bottle wall. In other embodiments, the bottle base may be bonded to the bottle wall or each bottle wall by a suitable bonding method, such as by adhesive, by welding or similar techniques.

[0029] In some embodiments, the material forming the bottle base and bottle walls is a sheet metal. In some embodiments, the sheet metal is a metal that does not react with the beverage due to the inherent non-reactivity of the metal or due to a surface coating or treatment applied to the metal. An example of a suitable sheet metal is food-grade stainless steel.

[0030] In other embodiments, the material forming the bottle base and bottle wall is a plastic material. Most preferably, the plastic material is free of 5-bisphenol A (BPA).

[0031] The material forming the bottle can have medium or low thermal conductivity. The material forming the bottle can have a thermal conductivity of less than 60 W / mK or less than 46 W / mK.

[0032] In some embodiments, the cup base has a shape that is substantially the same as that of the bottle base.

[0033] In some embodiments, the cup base is formed as part of the same component as the cup wall or each cup wall, and is thus continuously bonded to the cup wall or each cup wall. In other embodiments, the cup base may be bonded to the cup wall or each cup wall by a suitable joining method, such as by using adhesives, by welding, or similar techniques.

[0034] In some embodiments, the material forming the cup base and cup walls is a sheet metal. In some embodiments, the sheet metal is a metal that does not react with the beverage due to the inherent non-reactivity of the metal or due to a surface coating or treatment applied to the metal. An example of a suitable sheet metal is food-grade stainless steel.

[0035] In other embodiments, the material forming the cup base and the bottle cup is a plastic material. The plastic material may be bisphenol A (BPA) free.

[0036] The material forming the cup may have medium or low thermal conductivity. Preferably, the material forming the cup has a thermal conductivity of less than 60 W / mK or less than 46 W / mK.

[0037] In some embodiments, the material forming the cup is the same as the material forming the bottle.

[0038] The cup is constructed and sized such that it covers at least a portion of the lower part of the bottle. The cup covers at least a majority of the lower part of the bottle. The contours and dimensions of the cup wall, or the inner surface of each cup wall, and the cup base are such that they substantially match the contours of the outer surface of the lower part of the bottle and the bottle base. This results in at least a portion or at least a majority of the lower part of the bottle being tightly covered by the cup.

[0039] In some embodiments, when the cup maximally covers the lower part of the bottle, at least a portion of the outer surface of the bottle base abuts against the inner surface of the cup base. In this context, the outer surface of the bottle base should be understood to include any edges surrounding the edge of the bottle base or other protrusions (projecting) from the outer surface of the bottle base.

[0040] In some embodiments, the outer surface of the bottle base may be configured such that a gap exists between at least a portion of the outer surface of the bottle base and the inner surface of the cup base when the cup maximally covers the lower part of the bottle. This gap collects any beverage residue within the cup when it is placed on the bottle. This configuration also prevents residue from being moved and flowing out of the cup when it is placed on the bottle.

[0041] In some embodiments, the cup can be slidably placed on the lower part of the bottle. In some embodiments, the lower part of the bottle and the cup are sized such that the cup is held on the lower part of the bottle by frictional grip.

[0042] The cup can be constructed such that the dimensions of the outer surface of the cup at or near the rim are approximately the same as the dimensions of the outer surface of the upper part of the bottle at or near the second intermediate position. This has the effect that the combined outer surface of the bottle and cup generally has a relatively smooth outer surface profile.

[0043] In some embodiments, the cup fully covers the lower part of the bottle, such that the gap between the edge of the cup wall or each cup wall adjacent to the rim of the cup and the edge of the upper part of the bottle adjacent to the lower part is less than 5 mm, 4 mm, 3 mm or 2 mm.

[0044] In some embodiments, a gap exists between the edge of the cup wall or each cup wall adjacent to the rim and the edge of the upper part of the bottle. In some embodiments, this gap is at least partially filled with a complete or partial sealing ring (which will be discussed further below) or sleeve. The dimensions of the sealing ring or sleeve may be determined such that the outer surface of the upper part of the bottle, the surface profile of the sealing ring or sleeve, and the outer surface of the cup form a generally smooth surface.

[0045] The sleeve can be formed from an elastomeric material, which can be an insulating elastomeric material. Suitable materials for sleeves include, for example, silicone resins, plant-derived rubbers (such as guar gum rubber), soft BPA-free plastics (such as LDPE), or carbon-based polymers. For aesthetic purposes, the sleeve can be formed in a color that contrasts with the bottle and cup. The sleeve can feature images or text. Other possible sleeve materials are plant-derived rubbers, such as guar gum rubber.

[0046] In some embodiments, at least a majority of the lower portion of one or more bottle sidewalls has a wall thickness up to a first wall thickness, and at least a majority of the upper portion of one or more bottle sidewalls has a wall thickness of at least a second wall thickness, wherein the second wall thickness is greater than or equal to the first wall thickness.

[0047] This structure is advantageous because it allows the outer surface of the bottle to be constructed as described above, while the inner surface of the bottle is smooth between the base and the neck. This smooth inner surface of the bottle is particularly important for allowing for complete cleaning of the inner surface.

[0048] In some embodiments, the bottle is formed by walls comprising an inner surface layer and an outer surface layer. In some embodiments, the inner surface layer and the outer surface layer at the top of the bottle are spaced apart from each other. The space between the inner surface layer and the outer surface layer may be occupied by a gas or a mixture of gases. The gas may be an inert gas, such as argon, xenon, or krypton. Alternatively, the gas may be another gas or a mixture of gases, such as air. In use, the gas acts as an insulator between the inner surface layer and the outer surface layer of the bottle. The advantage of using air between the inner surface layer and the outer surface layer is that it minimizes the ecological impact or filling cost of the space between the inner surface layer and the outer surface layer. In other embodiments, a gas or mixture of gases at sub-atmospheric pressure may be used to occupy the space between the inner and outer walls. The sub-atmospheric pressure may be between a vacuum and about one atmosphere (about 101.3 kPa). Again, this filling of the space between the inner surface layer and the outer surface layer helps to insulate the contents of the bottle from the outside. In other embodiments, the space between the inner surface layer and the outer surface layer may be at least partially occupied by a foam or fibrous material, which also acts as an insulator.

[0049] For the lower portion of the bottle wall, the same considerations and possible structures apply as for the upper portion. In some embodiments, the space between the inner and outer surfaces of the lower portion of the bottle communicates with the space between the inner and outer surfaces of the upper portion of the bottle. It should be understood that, since the lower portion of the bottle wall is thinner than the upper portion, the insulation performance of the lower portion is expected to be lower than that of the upper portion.

[0050] In use, when the cup covers the bottom of the bottle, the lower insulation performance of the bottom of the bottle is compensated by the cup. This is because the cup of the drinking container surrounds and insulates the bottom of the bottle when it covers it. In some embodiments, the insulation of the cup is achieved due to the cup sidewalls having inner and outer cup surfaces spaced apart from each other. Like the bottle walls, the space between the inner and outer cup surfaces can be occupied by a gas or a mixture of gases. This gas can be an inert gas, such as argon, xenon, or krypton. Alternatively, the gas can be another gas or mixture of gases, such as air. In use, the gas acts as an insulator between the inner and outer cup surfaces. The use of air is advantageous because it minimizes the ecological impact or filling cost of the space between the inner and outer surfaces. In other embodiments, a gas at a pressure below atmospheric pressure can occupy the space between the inner and outer cup surfaces. This pressure below atmospheric pressure can be between a vacuum and approximately atmospheric pressure (approximately 101.3 kPa). Similarly, this filler used for the space between the inner and outer layers helps to insulate the contents of the bottle from the outside. In other embodiments, the space between the inner and outer layers may be at least partially occupied by a foam or fibrous material, which can also act as a thermal insulator.

[0051] When the cup covers the bottom, the combined insulation provided by the bottom of the bottle and the cup can be equal to or greater than the insulation provided by the top of the bottle. This has the advantage that when the bottle is only partially filled, and therefore the contents are more susceptible to temperature changes than when the bottle is full, the contents will receive more insulation from the combination of the bottle and the cup when the drinking container is oriented so that the cup base is lowest than when the bottle is full.

[0052] In some embodiments, the portion of the lower part of the bottle extending to a first intermediate position on the bottle may be influenced by the desired volume or capacity of the cup. This volume is defined by the inner surface of the cup base and the cup wall or each cup wall. The larger the desired volume of the cup, the farther the first intermediate position is from the bottle base.

[0053] In some alternative embodiments, the location of the first intermediate position is predetermined, and the size of the cup is calculated to match the location of the first intermediate position.

[0054] In some embodiments, the portion of the second intermediate position on the bottle may substantially coincide with the first intermediate position. In such embodiments, the thickness of the wall may vary gradually between the lower and upper portions. This step is located on the outer surface of the bottle wall or multiple bottle walls. In other embodiments, a taper may exist between the outer surface of the lower portion of the bottle wall and the outer surface of the upper portion of the bottle wall.

[0055] In some embodiments, a sealing ring is provided that extends around the outer surface of the bottle and covers a portion of the lower part of the bottle. The sealing ring can be held in place by one or two suitable adhesives, or when the sealing ring is positioned in the position extending around the bottle, the sealing ring is elastically stretched and then allowed to relax so that a force attempting to retract the sealing ring back to its original size (smaller than the portion of the lower part of the bottle where the sealing ring is located) holds the sealing ring in place.

[0056] In the foregoing embodiments, the sealing ring and the inner surface of the cup are configured such that when the cup maximally covers the lower part of the bottle, the inner surface of the cup's sidewall at least partially covers the sealing ring. In this position, the inner surface of the cup can at least partially compress the sealing ring. This causes the sealing ring to clamp onto the inner surface of the cup and hold the cup in place when seeking decompression, until the cup is pulled away from the sealing ring. The sealing ring can be made of silicone rubber, as silicone rubber is heat-resistant and suitable for constructing drinking containers. Other possible materials are plant-derived rubbers, such as guar gum rubber, soft BPA-free plastics (e.g., LDPE), or carbon-based polymers.

[0057] In some embodiments, the first intermediate position and the second intermediate position are spaced apart from each other. In such embodiments, the outer surface of the bottle preferably has a profile that creates a waist or narrowing between the first and second intermediate positions. The cross-section of this waist or narrowing is smaller than the cross-section of the lower or upper portion of the bottle adjacent to the waist or narrowing. In such embodiments, a sealing ring is provided, which is sized and configured such that at least a portion of the sealing ring will occupy the waist or narrowing.

[0058] When the sealing ring is positioned to extend around the bottle and cover the waist or narrower section, it can elastically stretch and relax to allow it to contract back to its original size (smaller than the waist or narrower section) to hold the ring in place. This design eliminates the need for adhesives to hold the ring in place. The elimination of adhesives is advantageous because adhesives are generally solvent-based, and the release of these solvents when such adhesives cure is harmful to the environment.

[0059] The sealing ring can be configured such that the cup can be reversibly pushed into a position where at least a portion of the sealing ring is covered by the inner surface of the cup wall and compressed by the cup wall. As a result, the cup is held in place by the sealing ring.

[0060] In some embodiments, the cup further includes a storage recess and a lid, wherein the lid is configured to reversibly engage with the rim of the cup and / or the cup wall or each cup wall to reversibly close the rim. The storage recess is configured to reversibly retain the lid within the storage recess.

[0061] This configuration allows the user to place the lid within the storage recess when the cup is to cover the bottom of the bottle. To use the cup, remove it from the bottom of the bottle and remove the lid from the storage recess. The beverage can then be poured from the bottle into the cup, and the lid can be used to seal the opening. Preferably, the lid includes one or more openings through which the beverage can be drunk. The lid may also include a closure device to reversibly close the opening or each opening. In some embodiments, this closure device may form a liquid seal.

[0062] Some embodiments of the lid allow the drinking container to have a "travel mug" configuration, which allows the user to drink from the cup while minimizing any spillage when the cup is gently pushed or bumped. Another benefit of the lid is that it helps prevent any beverage in the cup from cooling or warming up depending on the beverage's initial temperature relative to the ambient temperature.

[0063] In some embodiments, the lid is configured such that the portion of the lid that engages with the rim of the cup, or with the cup wall adjacent to the rim, and / or with the storage recess is elastically deformable. In such embodiments, the lid is held in place in the storage recess or the rim of the cup is closed by the elastic deformation of the deformable portion of the lid.

[0064] A storage recess in the cup may be defined by a cup base and one or more storage recess walls. The storage recess walls may extend in a direction away from the cup rim and cup base. The storage recess walls thus form a recess that faces a surface when the cup is placed on a surface with the rim at its uppermost position. In some embodiments, the storage recess is deep enough that the cup lid can be completely accommodated within the recess. In some embodiments, when the cup lid is fully within the storage recess, the cup lid does not contact a flat surface on which the cup is placed when the rim is furthest from the surface.

[0065] In some embodiments, the lid and the rim of the cup, or the cup wall adjacent to the rim, or each cup wall, are provided with mechanical means, such as threads, for engaging with each other. In such embodiments, similar mechanical means are also provided on the inner surface of the storage recess, such that the lid can be mechanically engaged within the storage recess to hold the lid in that position.

[0066] In some embodiments, the bottle cap comprises an outer cap layer and an inner cap element, the outer cap layer being configured and sized to reversibly engage with the bottle neck or the bottle wall or each bottle wall adjacent to the bottle neck, and the inner cap element being configured to reversibly engage with the outer cap layer. In such embodiments, the outer cap layer is preferably formed of an inert material such as metal or plastic and reversibly seals the bottle neck such that liquid cannot escape from the bottle when it is sealed.

[0067] In some embodiments, the inner cap element may be removed from the outer cap surface and thus interchangeable with each other in cap elements of different configurations. For example, a first inner cap element may include a raised strip extending on the surface of the inner cap element away from the outer cap surface. This strip may serve as a handle for moving the bottle cap. In some embodiments, it may include an opening through the strip to allow attachment of a handle or other accessory. A second inner cap element may be configured with a different configuration or may have a different color, allowing bottle users to personalize their bottles. The inner cap element preferably also functions as a thermal insulator.

[0068] In some embodiments, the means for engaging the outer cap surface and the inner cap element is a thread. In some embodiments, the thread is a left-hand thread.

[0069] In some embodiments, the means for joining the outer cup surface and the inner cap element is an adhesive or welding.

[0089] refer to Figure 1 and Figure 2 The drinking container 2 consists of a bottle 4, a cup 6, and a bottle cap 8.

[0090] refer to Figure 3 , 4Bottle 4 comprises an inner surface element 10, a first outer surface element 12, and a second outer surface element 14. The inner surface element 10 is configured to be inserted into and spaced apart from the outer surface elements 12 and 14, except for a mouth edge 16. The mouth edge 16 is adapted to engage with a mouth edge portion 18 of the second outer surface element 14. The mouth edge 16 is adapted to be engaged with the mouth element 18 by folding, pressing, welding, gluing, or other suitable joining methods.

[0091] The first outer surface element 12 includes a base 20, a sidewall portion 22, and an upper edge 24. The upper edge 24 is adapted to engage with the lower edge 26 of the second outer surface element 14. The engagement between the upper edge 24 and the lower edge 26 is also formed by folding, pressing, welding, gluing, or other suitable joining methods.

[0092] To construct the bottle, a portion 28 of the inner surface layer 10 lies within the volume defined by the outer surface layer 12, a second element 14 of the outer surface layer is placed on top of the inner surface layer 10, and edges 16 and 18 are joined in the same manner as edges 24 and 26. This creates a gap 30 between the inner surface layer 10 and the now complete outer surface layer 12 / 14.

[0093] refer to Figure 6 and 7 The cup 6 comprises an outer surface layer 32 and an inner surface layer 34. The inner surface layer 34 includes a mouth edge element 36, and is configured and sized to be embedded within the outer surface layer 32 in such a manner that the mouth edge element 36 contacts the mouth edge engagement portion 38 of the outer surface layer 32. The mouth edge element 36 is adapted to be joined to the mouth edge engagement element 38 by welding, using adhesives, or other fixing methods.

[0094] refer to Figure 8 , 9 10. The bottle cap 8 consists of an outer cap element 40 and an inner cap element 42. The inner cap element 42 is sized and configured to fit within a volume defined by the outer cap surface 40. In the illustrated embodiment, the inner cap element 42 is secured to the outer cap surface 40 by an adhesive. In other embodiments not shown, the outer cap surface 40 and the inner cap element 42 are configured such that the inner cap element 42 is held within the outer cap surface 40 by friction or mechanical interference.

[0095] The bottle cap 8 has a handle 44 integrated with the inner cap element 42. The handle 44 can be used to rotate the bottle cap 8. Rotation of the bottle cap 8 does not cause the inner cap element 42 to leave the volume defined by the outer cap surface 40, either wholly or partially, because the inner cap element 42 is permanently or reversibly secured in the outer cap surface 40. The handle 44 of the inner cap element 42 includes a hole 46 that allows a hook, ring, or other securing device to engage with the bottle cap 8. This securing device can also be attached to the bottle 4 to prevent the bottle cap 8 from being lost, or it can be used to attach the bottle to an external object—such as a backpack or belt—to prevent the drinking container from being lost.

[0096] refer to Figure 2 The cup 6 includes a circular cup base 46, side walls 48, and a recessed wall 50. The recessed wall 50, together with the cup base 46, defines a storage recess. The storage recess has a storage recess opening 52, which is defined by a free edge 53 of the recessed wall and faces away from the bottle cap 8.

[0097] refer to Figure 11 , 12 As shown in Figures 13, the bottle 2 of the embodiment of the invention also includes a cup lid 54. The cup lid 54 consists of a lid band 56, a lid plate 58, and a deformation zone 51 radially inward of the lid band 56. The lid band 56, the deformation zone 51, and the lid plate 58 are formed of an elastomeric material such as silicone rubber and are integral with each other.

[0098] The cup lid 54 includes a first drinking hole 62 and a vent hole (not shown).

[0099] The lid 54 is sized such that it can be reversibly positioned within a storage recess defined by the recess wall 50 and the cup base 46. The free edge 53 of the recess wall 50 includes a retaining plate 55 and a retaining ridge 57. The retaining plate has a circular section that partially closes the opening of the storage recess. The retaining ridge 57 extends around the portion of the free edge 53 that does not engage with the retaining plate 55 and again partially closes the opening of the retaining plate. The lid and storage recess are sized such that when the lid 54 is pushed into the storage recess, the lid clamp 56 and the deformation zone 51 elastically deform / compress, allowing the lid to pass through the opening defined by the retaining plate 55 and the retaining ridge 57. Once within the storage recess, some of the elastic deformation is eliminated, and the still-deformed lid clamp presses against the inner surface of the recess wall 50. The retaining plate 55 and the retaining ridge 57 press against / abut against the inner surface of the recess wall 50 to retain the cup lid within the storage recess. The user can deform the cap clamp 56 and the deformation zone 51 to remove the cup lid 54 from the storage recess. The retaining plate 55 is sized such that the opening 62 of the cup lid and the adjacent portion of the cap clamp 56—the portion of the cap clamp that the user's lips might touch when drinking from the opening 62—can be completely covered by the retaining plate when the cup lid is in the storage recess. This is necessary for hygiene reasons.

[0100] The dimensions of the mouth of the cup 6 and the dimensions and configuration of the cap clamp 56 are such that the cap clamp 56 can sealably and reversibly clamp the portion 68 of the cup and close the mouth of the cup.

[0101] refer to Figure 14 , 15 Figures 16 and 17 illustrate an alternative embodiment of the cup lid 154. The cup lid 154 comprises a first lid element 186 and a second lid element 188. The first lid element 186 includes an opening 162 for a user to drink from, a lid edge 156, and a deformable region 151. The first lid element also includes a circular opening defined by an edge 190, which is configured to receive a hinge pin 192, which is part of the second lid element 188. This opening is located on the first lid element 186 (e.g., on the upper surface of the first lid element 186). Figure 15 The surface shown is circular in the plane.

[0102] The second cover element 188 includes a hinge pin 192, an orifice closure element 194, a vent 200, and an arcuate slit 196. The hinge pin 192 is configured to slidably engage with an edge 190 of the first cover element 186 and is rotatable about a longitudinal axis of the hinge pin within an orifice defined by the edge 190. The orifice closure element 194 is located between the arcuate slit 196 and the radially outer edge of the second cover element 188, and is approximately located at the center of the arcuate slit 196.

[0103] The first and second cover elements 186 and 188 are both made of food-grade silicone rubber and are elastically deformable.

[0104] The rotation of hinge pin 192 about its longitudinal axis allows the second cover element to be moved from such a position as... Figure 15 Move the opening position shown to the left. Figure 17 The closed position shown.

[0105] In the open position, the orifice 162 is open and the user can drink through the orifice 162.

[0106] In the closed position, the orifice sealing element 194 is located in the orifice 162 and prevents liquid from flowing through the orifice 162.

[0107] The movement of the second cover element 188 from the open position to the closed position causes the closing element 194 to interfere with a portion of the cover edge 156. To overcome this interference, the arcuate slit 196 allows a portion of the second cover element 188 to bend / deform away from the cover edge 156 until the orifice closing element 194 enters the orifice 162, at which point the bent / deformed portion of the second cover element returns to its original non-bent / deformed position.

[0108] Cover 154 to Figures 11 to 13The lid 54 shown is inserted into the storage recess in the same manner. However, in this case, there is no retaining plate, and the retaining ridge 57 extends completely around the opening of the storage recess. The lid 154 is fitted onto the cup in the same manner as the lid 54.

[0109] Bottle 4 includes a lower region 70 that extends from a point adjacent to the bottle base 20 to a first intermediate position 74. The outer surface of the outer layer 12 generally forms the entire lower region 70. A second intermediate position 76 is spaced apart from the first intermediate position 74, and an upper region of the bottle extends from the second intermediate position 76 to a second position 78. Bottle 4 tapers gradually from the second position 78 toward the bottle neck.

[0110] Between the first and second intermediate positions 74, 76, the bottle wall is a single surface layer to form a waist 80, which has a smaller cross-section than the lower region 70 of the bottle at the first intermediate position 74 or the upper region 72 of the bottle at the second intermediate position 76. The waist has a sealing ring 82 located therein, which is held in place by elastic deformation of the sealing ring and the ends of the lower and upper regions 70 and 72. The sealing ring 82 is configured such that when the cup 6 is pushed to a position covering the entire lower region 70 and engaging with the sealing ring 82, the engaging portion 68 of the cup 6 covers and compresses the sealing ring 82. The sealing ring 82 is preferably made of an elastomeric material such as silicone and provides thermal insulation for the waist 80 of the bottle 4.

[0111] In the illustrated embodiment, the space 30 between the inner and outer surfaces of bottle 4 is filled with air. Air is a good insulator, therefore bottle 4 is insulated and can keep hot drinks hot or cold drinks cold. The lower part 70 of the bottle is further insulated by cup 6, which also has air between the outer surface 32 and the inner surface 34 of the cup.

[0112] In the illustrated embodiment of the invention, there is a small space between the inner surface of the inner layer 34 of the cup 6 and the outer surface of the outer layer 12 of the bottle 4. In other embodiments not illustrated, the cup and bottle are sized such that the inner surface of the cup 6 slides in contact with the outer surface of the lower region 70 of the bottle 4.

[0113] In use, beverages such as hot coffee are stored in a volume 84 defined by the inner surface of the inner surface layer 10 of the bottle 4 until the user wishes to drink the beverage. The cup 6 is positioned such that it covers and holds the lower region 70 of the bottle 4 in that position. When the user wants to drink part or all of the beverage, the user removes the cup 6 from the base of the bottle 4 and removes the lid 54 from the storage recess at the base of the cup. The bottle cap 8 is removed and the beverage is poured into the cup 6. The lid 54 is placed into the mouth of the cup 6. The cup 6 now functions as an insulated travel mug and allows the user to sip the beverage through the drinking spout 62 of the lid 54. When the user has finished drinking their beverage, the lid 54 is returned to the storage recess and the cup 6 is returned to its proper position on the bottle 4.

[0114] Unless otherwise stated, the drinking container 2 in the illustrated embodiment is formed of stainless steel components. This has the advantage of producing a robust drinking container that resists reaction with beverages without surface treatment.
