Definitions
- the invention relates to the field of closures with hinged lids for bottles and the like. More particularly, the invention relates to a closure with a hinged lid for bottles and the like having an automatic lid opening system comprising an improved button, said closure comprising:
- documents EP0826606, EP0839735 and EP0975526 describe a closure of the type described at the beginning.
- a first characteristic of this closure is that the elastic element made from elastomer material extends over the lid and the main body covering the anchoring means, so that said anchoring means are pleasant to touch when the user acts upon them to release them.
- these anchoring means do not form a proper button and suffer from the drawback that an additional amount of elastomer material is required that must be moulded according to a relatively complicated shape, which has a negative affect on the closure's manufacturing cost.
- a second characteristic of the closure disclosed by said documents EP0826606, EP0839735 and EP0975526 is that the elastic element has an extendible section that passes from one side to the other of the hinge joint when the lid pivots between its open and hinged positions. Consequently, said extendible section is extended to the maximum when the lid is in an intermediate position, whereby the lid has two rest positions: the open position and the hinged position.
- the lid When the lid is in the hinged position and the user wants to open it, he must release the anchoring means and push the lid against the force of the elastic element, beyond the intermediate position.
- This mode of operation suffers from the drawback that it complicates the lid opening operation for the user, and does not open the lid automatically and completely with one simple pressing action.
- a third characteristic of the closure disclosed in said documents EP0826606, EP0839735 and EP0975526 is that, in addition to forming an extendible section on level with the hinge joint so as to produce a spring-back function for the lid, the elastomer material also extends over part of the lid to ensure the seal of the supply hole.
- the elastomer material extends over the outer wall of a pin that is provided on the lid and which is forcibly inserted into the supply mouth, whereby the elastomer material is compressed between the outer wall of the pin and the inner wall of the supply mouth.
- Document EP0976663 discloses a closure of the type considered at the beginning, but which is different to the closure disclosed in the said documents EP0826606, EP0839735 and EP0975526 because the lid's only rest position is the open position, which corresponds to a minimum extension of the extendible section of the elastic element.
- This mode of operation is obtained by virtue of the elastic element having an extendible section that is arranged between two ribs that form the hinge joint, and is joined to said ribs, so that said extendible section cannot pass freely from one side to the other of the hinge joint.
- the closure comprises an elastic button made from the elastomer material.
- the lid is provided with a pin that is inserted into said supply mouth, but contrary to the closures cited above, the elastomer material does not extend over the pin, instead it forms the top edge of the supply mouth on the main body.
- the extendible section of the elastic element must exert a strong spring-back force.
- said extendible section has limited elasticity, since it is attached to the ribs forming the hinge joint. Consequently, the lid's opening movement is fairly abrupt, which is not very pleasant for the user.
- the design of the push button formed by the elastomer material has a negative affect on the closure's manufacturing costs.
- Document JP8113260 relates to a closure that resembles the type of closure referenced in the invention, but wherein the anchoring means are not released by means of a button, but rather by traditional means, pulling a visor provided on the lid.
- the elastomer material only performs the lid's spring-back function, and it consists of a separate part that fits at its ends into housings provided in the lid and in the main body of the closure, and has an intermediate extendible section that is freely positioned externally with respect to the hinge joint.
- the lid's only rest position is the open position, which corresponds to a maximum extension of the extendible section.
- the aim of the invention is to provide a closure of the type indicated at the beginning, which enables the lid to be opened automatically and completely by acting upon a button with a simple, comfortable action, and which does not suffer from the drawbacks of the known closures mentioned above.
- the main aim of the invention is to provide a closure with a button that acts quickly releasing the anchoring means between the lid and the main body, without it being necessary to use elastomer material to form the button and without significantly complicating the manufacturing process.
- the main body has a side wall and an upper base on which the supply mouth is provided;
- the button is made up of a movable area that is moulded integrally together with said main body in rigid plastics material and which comprises at least one front portion delimited on said side wall and joined at its lower end thereto by a joining line that defines a pivoting axis for said movable area, said front portion having a pressing surface that is suitable for receiving a user's finger; and the anchoring means comprises a first part formed in said movable area and a second part formed on said lid and suitable for being anchored in said first part.
- This closure according to the invention does not require using elastomer material to form the button; it is based on local geometric forms defined in the actual rigid plastics material of the main body and the lid. Moreover, thanks to the fact that the first part of said anchoring means is provided in the movable area of the main body, when the button is activated, the second part of the anchoring means are released directly and the lid is opened.
- the surface for activating the button is located in the actual movable area, whereby the user acts directly on the movable area.
- This direct activation and release combined with the spring-back force exerted by the elastic element provided between the lid and the main body, easily and effectively opens the lid.
- the user acts upon the pressing surface defined on the front portion of the button, in other words on the side wall of the main body, so that the lid can be opened comfortably with one simple finger movement, while holding the bottle in one hand.
- said movable area is delimited on said main body by a deformable contour defined by a geometric weakening of the actual wall of said main body.
- This deformable contour makes the button more robust and, since it is deformable, allows the movable area limited but sufficient pivoting around the joining line.
- the geometric weakening of the wall of the main body that forms said deformable contour has, in section, a toggled shape and a reduced thickness with respect to the adjacent areas of said wall.
- the deformable contour can be slightly stretched and contracted, allowing the movable area sufficient movement to release the anchoring means.
- this geometric arrangement can be obtained easily during the moulding operation for the closure's main body.
- said deformable contour has an upper section that defines in said upper base an upper part of the movable area and respective side sections that define in said side wall the front portion of the movable area, said side sections extending the ends of said upper section as far as said joining line.
- said geometric weakening forms said deformable contour in the shape of a groove the depth of which decreases in said side sections towards the lower ends thereof, which reinforces the button without considerably affecting the pivoting of the deformable area around the joining line.
- the anchoring means consist of a window in said front portion of the movable area and a hook-shaped projection formed on the lid.
- the moveable area is moved away from the side wall thereby unhooking the projection from the window.
- said deformable contour defines a continuous joining surface between said movable area and the rest of said main body, thereby preventing dirt or any external element from entering through the deformable contour.
- the invention contemplates, optionally, some advantageous embodiments including characteristics regarding the elastic element and the parts of the main body and the lid that interact with it to perform the lid's spring-back function. These characteristics, in combination with those described above in connection with the button, contribute to obtaining an improved performance of the lid's automatic opening, in particular, a more effective opening that is not too abrupt, and which does not negatively affect closure manufacturing costs.
- the closure is shaped as follows:
- One of these advantageous solutions consists in the projection defining the seating surface extending from a lower end of the main body next to said first joining area of the elastic element, to an upper end that projects from said main body and that is next to said second joining area of the elastic element when the lid is in its hinged position.
- said seating surface has a convex shaped section on which the elastic element's extendible section rests in the lid's hinged position, therefore providing gentle support that prevents localised tension.
- said second joining area of the elastic element has an elongated shape that extends parallel to the axis of said hinge joint, and said elastic element has two of said first joining areas, separated by an open space facing said hinge joint, and two of said free extendible sections defined between said first joining areas and said second joining area, said main body comprising two of said projections that respectively define two of said seating surfaces positioned externally with respect to the hinge joint and respectively facing said two extendible sections of the elastic element.
- said main body and said lid have a contour that is truncated by respective flat surfaces joined by a bridge that forms said hinge joint, said projection protruding from the flat surface of the main body, and said flat surface of the lid having at least one window through which said projection and said extendible section of the elastic element protrude when the lid is in the hinged position.
- the invention also contemplates, optionally, some advantageous embodiments including characteristics regarding the lid's seal of the supply mouth. These characteristics are intended to provide a closure wherein the interaction between the lid and the supply mouth does not produce significant friction between these elements, so that when the anchoring means are released by acting upon the button, the lid opens without any impediment, stretched by the spring-back action of the elastic element, without the latter having to exert any significant force to unblock the supply mouth.
- said lid is provided on its inner surface with a flat contact area made from elastomer material and facing said supply mouth in the lid's hinged position, so that said flat contact area of the elastic element is applied against the upper edge of said supply mouth.
- This flat contact area made from elastomer material ensures the supply mouth has an airtight seal, without any outer or inner coupling with the supply mouth, whereby said supply mouth is unblocked simply by lifting the lid, without it being necessary to overcome any strong friction force.
- the inner surface of said lid has a hollow area that houses said flat contact area, and makes it easier to join it to the lid when manufacturing the closure.
- said elastic element made from elastomer material that ensures the lid's spring-back action, also forms said flat contact area. This avoids having different pieces of elastomer material and facilitates the closure manufacture process by overmoulding the elastomer material over the rigid plastics material of the main body and the lid.
- said elastic element comprises a connection strip that extends between said flat contact area and the part of the elastic element where the second joining area is provided, and the inner surface of said lid has a channel that leads into said hollow area and houses said connection strip.
- this solution facilitates forming the elastic element made from elastomer material with an overmoulding method, because the channel and the hollow area act as a mould.
- said flat contact area and said connection strip are arranged level with said hollow area and said channel, respectively, thereby preventing any projections on the inner surface of the lid where dirt could accumulate.
- the elastic element made from elastomer material is overmoulded on the piece of rigid plastics material made up of said main body and said lid, for example using a bi-injection method.
- said elastic element goes through the thickness of said lid from said contact area and forms an outer layer of elastomer material that extends over at least part of the lid's outer surface. This way the elastomer material can be injected over the lid's outer surface and, at the same time, an outer coating of elastomer material can be obtained that is suitable for forming a publicity or geometric motif that personalises the closure.

- the closure is made up of a main body 1 , which has a supply mouth 2 , and a lid 3 that is joined to the main body 1 by a bridge 4 that performs the functions of a hinge joint.
- Main body 1 and lid 3 are moulded as an integral part in a rigid plastics material, for example polypropylene. Lid 3 can pivot with respect to the axis formed by the hinge joint 4 between an open position and a hinged position wherein lid 3 blocks supply mouth 2 .

- a button suitable for operating the release of said anchoring means, so that by acting upon said button the lid is opened automatically and completely due to the action of the spring-back force exerted by said elastic element.
- Various closures of the type indicated at the beginning are known.
- For example, documents EP0826606, EP0839735 and EP0975526 describe a closure of the type described at the beginning. A first characteristic of this closure is that the elastic element made from elastomer material extends over the lid and the main body covering the anchoring means, so that said anchoring means are pleasant to touch when the user acts upon them to release them. However, these anchoring means do not form a proper button and suffer from the drawback that an additional amount of elastomer material is required that must be moulded according to a relatively complicated shape, which has a negative affect on the closure's manufacturing cost.
- A second characteristic of the closure disclosed by said documents EP0826606, EP0839735 and EP0975526 is that the elastic element has an extendible section that passes from one side to the other of the hinge joint when the lid pivots between its open and hinged positions. Consequently, said extendible section is extended to the maximum when the lid is in an intermediate position, whereby the lid has two rest positions: the open position and the hinged position. When the lid is in the hinged position and the user wants to open it, he must release the anchoring means and push the lid against the force of the elastic element, beyond the intermediate position. This mode of operation suffers from the drawback that it complicates the lid opening operation for the user, and does not open the lid automatically and completely with one simple pressing action.
- A third characteristic of the closure disclosed in said documents EP0826606, EP0839735 and EP0975526 is that, in addition to forming an extendible section on level with the hinge joint so as to produce a spring-back function for the lid, the elastomer material also extends over part of the lid to ensure the seal of the supply hole. In particular, the elastomer material extends over the outer wall of a pin that is provided on the lid and which is forcibly inserted into the supply mouth, whereby the elastomer material is compressed between the outer wall of the pin and the inner wall of the supply mouth. This solution suffers from the drawback that the pin is firmly wedged in the supply mouth, and so considerable force is required to open the lid.
- Document EP0976663 discloses a closure of the type considered at the beginning, but which is different to the closure disclosed in the said documents EP0826606, EP0839735 and EP0975526 because the lid's only rest position is the open position, which corresponds to a minimum extension of the extendible section of the elastic element. This mode of operation is obtained by virtue of the elastic element having an extendible section that is arranged between two ribs that form the hinge joint, and is joined to said ribs, so that said extendible section cannot pass freely from one side to the other of the hinge joint. With respect to the opening system, in this case the closure comprises an elastic button made from the elastomer material. The user presses said elastic button to release the anchoring means and thus causes the lid to open automatically thanks to the spring-back force exerted on said lid. As for the seal of the supply mouth, in this case the lid is provided with a pin that is inserted into said supply mouth, but contrary to the closures cited above, the elastomer material does not extend over the pin, instead it forms the top edge of the supply mouth on the main body. In order to open the lid considerable force is required to extract the pin inserted into the supply mouth. Therefore, so that the lid opens automatically once the anchoring means have been released, the extendible section of the elastic element must exert a strong spring-back force. Furthermore, said extendible section has limited elasticity, since it is attached to the ribs forming the hinge joint. Consequently, the lid's opening movement is fairly abrupt, which is not very pleasant for the user. Also, the design of the push button formed by the elastomer material has a negative affect on the closure's manufacturing costs.
- Document JP8113260 relates to a closure that resembles the type of closure referenced in the invention, but wherein the anchoring means are not released by means of a button, but rather by traditional means, pulling a visor provided on the lid. In this case, the elastomer material only performs the lid's spring-back function, and it consists of a separate part that fits at its ends into housings provided in the lid and in the main body of the closure, and has an intermediate extendible section that is freely positioned externally with respect to the hinge joint. The lid's only rest position is the open position, which corresponds to a maximum extension of the extendible section. This is achieved by virtue of a projection, provided on the outer surface of the lid, which receives and supports said extendible section and keeps it positioned externally with respect to the hinge joint. This projection arrangement suffers from the drawback that it imposes significant restrictions on the lid's external design. For example, it makes it impossible to design a lid with a clear outer surface. Another drawback of this arrangement is that the projection has a reduced support surface that causes localised tension and wears the extendible section of the elastic element. Moreover, by arranging said projection it is not possible to manufacture the closure as an integral part by overmoulding the elastomer material, since the part cannot be stripped from the mould.
- Document WO2004110889 discloses a type of closure in which the hinge joint is made from the actual elastic element arranged as a single connection means between the lid and the main body. This solution is different to the type of closure described in the invention and suffers from the drawback that it considerably complicates closure manufacturing. Moreover, in this case the closure does not comprise anchoring means in the strict sense; the function of maintaining the lid in its hinged position is carried out by the actual pin provided on the lid, which is inserted into the supply mouth to seal it and remains fixed therein by virtue of friction. The closure is provided with a button that is operated by pressing the lid upwards until the pin withdraws from the supply mouth. This opening system suffers from the drawback that the user must act upon the button, moving it sufficiently to remove the pin from the supply mouth. This is not very comfortable and differs from the operation of a proper button, which must act instantly.
- The aim of the invention is to provide a closure of the type indicated at the beginning, which enables the lid to be opened automatically and completely by acting upon a button with a simple, comfortable action, and which does not suffer from the drawbacks of the known closures mentioned above.
- In particular, the main aim of the invention is to provide a closure with a button that acts quickly releasing the anchoring means between the lid and the main body, without it being necessary to use elastomer material to form the button and without significantly complicating the manufacturing process.
- This aim is achieved by means of a closure of the type indicated at the beginning, characterised in that the main body has a side wall and an upper base on which the supply mouth is provided; the button is made up of a movable area that is moulded integrally together with said main body in rigid plastics material and which comprises at least one front portion delimited on said side wall and joined at its lower end thereto by a joining line that defines a pivoting axis for said movable area, said front portion having a pressing surface that is suitable for receiving a user's finger; and the anchoring means comprises a first part formed in said movable area and a second part formed on said lid and suitable for being anchored in said first part.
- This closure according to the invention does not require using elastomer material to form the button; it is based on local geometric forms defined in the actual rigid plastics material of the main body and the lid. Moreover, thanks to the fact that the first part of said anchoring means is provided in the movable area of the main body, when the button is activated, the second part of the anchoring means are released directly and the lid is opened. The surface for activating the button is located in the actual movable area, whereby the user acts directly on the movable area. This direct activation and release, combined with the spring-back force exerted by the elastic element provided between the lid and the main body, easily and effectively opens the lid. In order to activate the button, the user acts upon the pressing surface defined on the front portion of the button, in other words on the side wall of the main body, so that the lid can be opened comfortably with one simple finger movement, while holding the bottle in one hand.
- Preferably, said movable area is delimited on said main body by a deformable contour defined by a geometric weakening of the actual wall of said main body. This deformable contour makes the button more robust and, since it is deformable, allows the movable area limited but sufficient pivoting around the joining line.
- Preferably, the geometric weakening of the wall of the main body that forms said deformable contour has, in section, a toggled shape and a reduced thickness with respect to the adjacent areas of said wall. By virtue of this particular shape, the deformable contour can be slightly stretched and contracted, allowing the movable area sufficient movement to release the anchoring means. Moreover, this geometric arrangement can be obtained easily during the moulding operation for the closure's main body.
- Advantageously, said deformable contour has an upper section that defines in said upper base an upper part of the movable area and respective side sections that define in said side wall the front portion of the movable area, said side sections extending the ends of said upper section as far as said joining line. With this arrangement a particularly robust button is obtained. When using the finger to press the pressing surface, the movable area is pivoted with little effort because the contour of the upper section contracts and the side sections are deformed sideways. The button only works if the pressing area is pressed in a direction that is noticeably perpendicular to the closure's side wall, thereby minimising the possibility that the lid opens accidentally when it comes into contact with some external element.
- Preferably, said geometric weakening forms said deformable contour in the shape of a groove the depth of which decreases in said side sections towards the lower ends thereof, which reinforces the button without considerably affecting the pivoting of the deformable area around the joining line.
- Preferably, the anchoring means consist of a window in said front portion of the movable area and a hook-shaped projection formed on the lid. When the user acts upon the pressing surface, the moveable area is moved away from the side wall thereby unhooking the projection from the window.
- Preferably, said deformable contour defines a continuous joining surface between said movable area and the rest of said main body, thereby preventing dirt or any external element from entering through the deformable contour.
- The invention contemplates, optionally, some advantageous embodiments including characteristics regarding the elastic element and the parts of the main body and the lid that interact with it to perform the lid's spring-back function. These characteristics, in combination with those described above in connection with the button, contribute to obtaining an improved performance of the lid's automatic opening, in particular, a more effective opening that is not too abrupt, and which does not negatively affect closure manufacturing costs.
- In an advantageous embodiment of the invention, the closure is shaped as follows:
-
- the elastic element has at least one first joining area fixedly attached to said main body and at least one second joining area fixedly attached to said lid, with at least one extendible section of said elastic element being defined between said first and second joining areas;
- the main body of the closure comprises at least one projection that defines a seating surface positioned externally with respect to said hinge joint; and
- said extendible section of the elastic element extends freely in front of said seating surface,
so that when the lid pivots towards its hinged position said seating surface receives said extendible section of the elastic element, which rests on said seating surface, and keeps said extendible section positioned externally with respect to the hinge joint. This arrangement ensures that the extendible section of the elastic element is always positioned externally with respect to the hinge joint, whereby the lid's only rest position is the open position that corresponds to a minimum extension of the elastic element's extendible section. By virtue of the fact that the extendible section is arranged freely opposite the seating surface, its elasticity is not affected by interference with the rigid elements of the closure. Moreover, providing said projection on the main body of the closure maintains the freedom of the lid's design, making particularly advantageous solutions possible.
- One of these advantageous solutions consists in the projection defining the seating surface extending from a lower end of the main body next to said first joining area of the elastic element, to an upper end that projects from said main body and that is next to said second joining area of the elastic element when the lid is in its hinged position. By virtue of this arrangement, when the lid is in the hinged position the extendible section of the elastic element rests its entire length on the seating surface, thereby avoiding localised tension and wear. Also said extendible section is prevented from catching on any outside body while the bottle incorporating the closure is in transit or being handled.
- Preferably, said seating surface has a convex shaped section on which the elastic element's extendible section rests in the lid's hinged position, therefore providing gentle support that prevents localised tension.
- In a preferred embodiment of the invention, said second joining area of the elastic element has an elongated shape that extends parallel to the axis of said hinge joint, and said elastic element has two of said first joining areas, separated by an open space facing said hinge joint, and two of said free extendible sections defined between said first joining areas and said second joining area, said main body comprising two of said projections that respectively define two of said seating surfaces positioned externally with respect to the hinge joint and respectively facing said two extendible sections of the elastic element. This arrangement distributes the elastic effort between two extendible sections, thereby allowing an improved spring-back force adjustment. Also, it makes it easier to form the hinge joint, which is framed at the sides by the two extendible sections.
- In an advantageous embodiment of the invention, said main body and said lid have a contour that is truncated by respective flat surfaces joined by a bridge that forms said hinge joint, said projection protruding from the flat surface of the main body, and said flat surface of the lid having at least one window through which said projection and said extendible section of the elastic element protrude when the lid is in the hinged position. This embodiment of the closure has the advantage that it is particularly compact.
- The invention also contemplates, optionally, some advantageous embodiments including characteristics regarding the lid's seal of the supply mouth. These characteristics are intended to provide a closure wherein the interaction between the lid and the supply mouth does not produce significant friction between these elements, so that when the anchoring means are released by acting upon the button, the lid opens without any impediment, stretched by the spring-back action of the elastic element, without the latter having to exert any significant force to unblock the supply mouth.
- So, in a preferred embodiment of the invention, said lid is provided on its inner surface with a flat contact area made from elastomer material and facing said supply mouth in the lid's hinged position, so that said flat contact area of the elastic element is applied against the upper edge of said supply mouth. This flat contact area made from elastomer material ensures the supply mouth has an airtight seal, without any outer or inner coupling with the supply mouth, whereby said supply mouth is unblocked simply by lifting the lid, without it being necessary to overcome any strong friction force.
- Preferably, the inner surface of said lid has a hollow area that houses said flat contact area, and makes it easier to join it to the lid when manufacturing the closure.
- Preferably, said elastic element made from elastomer material that ensures the lid's spring-back action, also forms said flat contact area. This avoids having different pieces of elastomer material and facilitates the closure manufacture process by overmoulding the elastomer material over the rigid plastics material of the main body and the lid.
- Preferably, said elastic element comprises a connection strip that extends between said flat contact area and the part of the elastic element where the second joining area is provided, and the inner surface of said lid has a channel that leads into said hollow area and houses said connection strip. In particular, this solution facilitates forming the elastic element made from elastomer material with an overmoulding method, because the channel and the hollow area act as a mould.
- Preferably, said flat contact area and said connection strip are arranged level with said hollow area and said channel, respectively, thereby preventing any projections on the inner surface of the lid where dirt could accumulate.
- Preferably, the elastic element made from elastomer material is overmoulded on the piece of rigid plastics material made up of said main body and said lid, for example using a bi-injection method. In an advantageous solution, said elastic element goes through the thickness of said lid from said contact area and forms an outer layer of elastomer material that extends over at least part of the lid's outer surface. This way the elastomer material can be injected over the lid's outer surface and, at the same time, an outer coating of elastomer material can be obtained that is suitable for forming a publicity or geometric motif that personalises the closure.

FIG. 17 , a partial perspective view, sectioned along a middle plane, of the closure inFIGS. 15 and 16 . -
FIGS. 1 to 13 illustrate a first embodiment of a closure according to the invention, which is intended to be applied to bottles of water and which enables the lid to be opened easily with the same hand that is holding the bottle, by using a finger to press a button provided on the closure's main body. - The closure is made up of a
main body 1, which has asupply mouth 2, and alid 3 that is joined to themain body 1 by abridge 4 that performs the functions of a hinge joint.Main body 1 andlid 3 are moulded as an integral part in a rigid plastics material, for example polypropylene.Lid 3 can pivot with respect to the axis formed by the hinge joint 4 between an open position and a hinged position whereinlid 3blocks supply mouth 2. Anelastic element 7, made from elastomer material, for example a thermoplastic elastomer (TPE), joinsmain body 1 andlid 3 so that it exerts a spring-back force onlid 3 towards its open position. As will be explained in detail below,elastic element 7 has anextendible section 7 c freely positioned externally with respect to hinge joint 4, so that whenlid 3 is closed, making it pivot from its open position,extendible section 7 c gradually becomes tenser and therefore always exerts a spring-back force onlid 3 towards its open position. -
Main body 1 has an overall cylindrical shape, with aside wall 11 and anupper base 12 in which supplymouth 2 is provided, and it has amovable area 5 delimited by adeformable contour 8 defined by a geometric weakness in the actual wall ofmain body 1, as can be seen in greater detail inFIGS. 4 to 6 . The geometric weakness that shapesdeformable contour 8 has, in section, a toggled shape and a reduced thickness with respect to the adjacent areas of the wall ofmain body 1, and defines a continuous joining surface between saidmovable area 5 and the rest ofmain body 1, as can be seen in particular inFIGS. 7 to 9 . The thus formeddeformable contour 8 has a U-shapedupper section 8 a provided inupper base 12 ofmain body 1 andrespective side sections 8 b that extend intoside wall 11 extending the ends ofupper section 8 a and defining in said side wall 11 afront portion 5 a ofmovable area 5. The lower end of saidfront portion 5 a, in to which the twoside sections 8 b lead, is joined toside wall 11 forming a joiningline 22 around whichmovable area 5 pivots. As can be seen inFIGS. 4 to 6 , the depth of the groove formed by the geometric weakness that shapescontour 8 decreases towards the lower ends ofside sections 8 a, as far as joiningline 22. Apressing surface 13, suitable for receiving a user's finger, is provided onfront portion 5 a ofmovable area 5. - The closure comprises anchoring means between
lid 3 andmain body 1 consisting of awindow 6 a infront portion 5 a ofmovable area 5 and a hook-shapedprojection 6 b formed onlid 3. In order to closelid 3, the user pivots it by acting against the spring-back force ofelastic element 7, until the lid reaches the hinged position shown inFIG. 9 , whereinprojection 6 b is anchored inwindow 6 a. - The thus formed
movable area 5 forms a button suitable for operating the release of said anchoring means 6 a, 6 b and causing the subsequent automatic opening oflid 3. To do this, the user presses pressingsurface 13 with his finger causingmovable area 5 to pivot slightly, the top part of which moves away fromwall 11, wherebyprojection 6 b withdraws fromwindow 6 a and releaseslid 3, which pivots to its open position thanks to the spring-back force exerted byelastic element 7. The pivoting ofmovable area 5 around joiningline 22 is accompanied by a transverse contraction ofupper section 8 a and a sideways deformation ofside sections 8 b and the longitudinal sides of saidupper section 8 a. - This embodiment of the closure according to the invention also includes some particular characteristics regarding
elastic element 7, and the parts ofmain body 1 andlid 3 that interact with it to perform the spring-back function oflid 3. As can be seen in particular inFIGS. 10 to 13 ,elastic element 7 has two joiningareas 7 a integral withmain body 1 and one second joiningarea 7 b integral withlid 3. Between the first joiningareas 7 a and the second joiningarea 7 b respectiveextendible sections 7 c of the elastic element are provided, which are freely positioned externally with respect to hinge joint 4. The first joining areas are separated by anopen space 23 that faces saidhinge joint 4.Main body 1 comprises twoprojections 9 that defineseating surfaces 10 positioned externally with respect to hinge joint 4 and face the elastic element'sextendible sections 7 c. Eachprojection 9 extends from a lower end located onmain body 1, next to a first joiningarea 7 a of the elastic element, to an upper end that projects frommain body 1 and is located next to the second joiningarea 7 b of the elastic element in the lid's hingedposition 3.Surface 10 formed on eachprojection 9 has a convex shaped section at the top thereof, whereas the lower part is flat to facilitate mould stripping. -
Main body 1 andlid 3 have a contour that is truncated by respectiveflat surfaces bridge 4 that forms the hinge joint.Projections 9 project fromflat surface 19 of the main body andflat surface 20 of the lid hasrespective windows 21 through whichprojections 9 andextendible sections 7 c ofelastic element 7 protrude in the hinged position oflid 3, as can be seen in FIGS. 11,12 and 13. - When
lid 3 pivots towards the hinged position illustrated inFIGS. 9 , 12 and 13, seating surfaces 10 receive and supportextendible sections 7 c ofelastic element 7 and keep them positioned externally with respect to hinge joint 4. By virtue of this arrangement, in any position oflid 3 between its open and hinged positions,extendible sections 7 c are extended elastically, with respect to their state in said open position oflid 3, whereby said open position is the only rest position oflid 3. As can be seen in said figures, in the lid's hinged position the entire length of each extendible section is applied againstsurface 10. - Also, this embodiment of the closure according to the invention includes particular characteristics regarding the lid's airtight seal of the supply mouth.
Elastic element 7 made from elastomer material extends, from the part where the second joiningarea 7 b is provided, along aconnection strip 15 to form at the end of the latter aflat contact area 14 betweenlid 3 andsupply mouth 2. The inner surface oflid 3 has achannel 16 that leads into said centralhollow area 17.Elastic element 7 made from elastomer material is formed by an overmoulding method over the piece of rigid plastics material formed bymain body 1 andlid 3, so thatconnection strip 15 andflat contact area 14 are provided on level, respectively, with saidchannel 16 and saidhollow area 17. As can be seen inFIG. 9 , in the hinged position oflid 3flat contact area 14 made from elastomer material is applied against the upper edge ofsupply mouth 2, without being inserted therein through friction. -
FIG. 14 illustrates a second embodiment that is a variant of the first. In this case,lid 3 has a central hole through which the elastomer material is injected in the overmoulding process, so thatelastic element 7 that is made from elastomer material and is formed by this process goes through the thickness oflid 3 from saidflat contact area 14 and forms anouter layer 18 of elastomer material that extends over part of the outer surface oflid 3. The shape and appearance of saidexternal layer 18 can be personalised for each closure. - Finally,
FIGS. 15 to 17 illustrate a third embodiment of the invention wherein anelastic element 7 has been provided with a single joiningarea 7 a joined to the second joiningarea 7 b by a singleextendible section 7 c.Main body 1 has a singlecentral projection 9. In this case,main body 1 andlid 3 do not have a contour that is truncated on level with hinge joint 4 as in the preceding embodiments, instead said contour is substantially circular. Hinge joint 4 is made up of two parts arranged on each side ofcentral projection 9.
