MXPA01007263A - Sport drinking cup with valved straw cap - Google Patents

Abstract

An easy-to-operate vented leak-proof drinking cup cap for a bottle is formed by a pivotable drinking spout (3) and diaphragm arrangement (4) in the cap base (7). The drinking spout that forms the mouthpiece on the upper side of the diaphragm through which the user sucks liquid, contains a portion (3b) on the underside the diaphragm. That lower spout portion carries an elastic hose or tube (8) for immersion in the bottle's liquid when the drinking spout is in the open position, whereby the series of passages through the elastic tube and drinking spout serves as a straw. When the spout is pivoted to its closed position and latched, in one movement, the lower portion of the spout swings a portion of the elastic tube against the vent (6), closing the vent, and forces another portion of that hose into aninterference surface (12), creating a bend or kink in the hose that prevents liquid passage.

Description

SPORTS VESSEL FOR DRINKING, WITH PROVIDED POPOTE LID WITH VALVE Technical Field This invention relates to sports drinking containers and more particularly to a sports drinking vessel containing a re-sealable straw-type member. Previous Technique Sports enthusiasts, particularly cyclists, are accustomed to transporting a container of water, which they are able to access efficiently, "on the fly" to quench their thirst.A common form of container is a flexible plastic bottle with a spout for Drinking that opens and closes manually Conveniently, the drinking spout serves as a drinking nozzle.When moving the spout to the open position, the cyclist inserts the spout into the mouth and compresses the bottle, expelling the drinking water. Another way is a plastic bottle that has a plastic straw to drink in. Being always open, the cyclist holds the bottle and with the end of the straw in his mouth, compresses it to expel the water to drink.

In addition, in my U.S. patent. No. 5,392,968 granted on February 28, 1995 with the title "Dispensing Closure and Method" (hereinafter referred to as the Dark patent). 968, a molded one-piece plastic fluid seal is disclosed to contain a pivotable spigot and a composite diaphragm, the disclosure of which is hereby incorporated by reference in its entirety. Other obvious aspects of the patent inspection also describe adaptations to this novel closure structure to allow the closure to serve as a sports drink container lid. The structure illustrated in Figures 20 and 21 of that patent employs a flexible thin-walled tubular extension formed integrally on the underside of a spout to supply fluid, thicker tubular-walled fluid, which is located on the underside of the base closing. With the spout in its vertical open position, the fluid confined within the associated bottle container is drawn through the spout. When the spout is pivoted down to the closed or sealed position and locked, the flexible tubular extension is pressed against a seal member, a plastic member depending on the underside of the closure base, folding and flattening a portion of the seal. tube to close the passage of fluid through.

An alternate embodiment described in the patent combines the closure of a piece with a separate flexible straw to form a two-piece structure. As illustrated in Figures 22 and 23 of that patent, a flexible plastic straw is inserted through the rigid spout and extends through the closure base and into the liquid confined in the container. When the pivotable spout is pivoted down to the closed or sealed position and locked, the pivoting spout twists the straw around and bends it, pressing a portion of the straw against a seal member. A plastic member that depends on the underside of the closure base and as in the preceding structure folds and flattens a portion of the straw to block the fluid passage. Although not specifically illustrated, the above beverage container lids may include conventional air ventilation, which extends through the closure base, to allow more liquid to be sucked out of the bottle. Ventilation allows air to enter the bottle as the liquid is sucked. Although novel, the above illustrated lid structures for drinking containers do not affect the market for reasons that are not fully described. The soft tube extending out of the nozzle was not acceptable and the lack of ventilation in the lid made the drinking container difficult to use. Preferably, air vents used in the lids of previous drinking vessels, are made small enough in size, so that the surface tension of the liquid confined only, avoid any leakage when the lid closes. A problem with small sized vents in rigid caps is that the liquid can only be sucked into the container as fast as outside air can enter, which is a nuisance for some. In addition, due to the varied nature of the liquids contained in water. Such as drinks, juices and water and to minimize the potential for shutting off that ventilation, where the operation would be more difficult, particularly for uninformed users who may not understand the purpose of air ventilation, the approach taken is to use a ventilation much wider than what would otherwise be necessary. As a consequence, the drinking container lid would allow somewhat less leakage and can not be characterized as leak proof. Good hygiene is a consideration that is sometimes neglected. To ensure that the "drinking vessel is sanitary, it must frequently be disassembled and washed." The most widely available drinking cup lid uses a push-pull valve that is made up of two components.This valve is not designed to be dismantled. Therefore, even when the drinking container and lid are washed in the normal way, particles of juice or other liquids may remain between the two valve components inside the valve, causing contamination. like those imported from China, they are manufactured and assembled from an even larger number of components.A drinking container product consists of a layer, a straw, a rubber tube that connects the straw with the spout and a This cap is not designed for cleaning and is almost impossible to sterilize. My invention is to provide a lid for drinking container, leak proof. Another object of the invention is to provide a leak-proof drinking container that takes advantage of some elements of my previous designs, while being manufactured and used more easily. A further object of the invention is to provide a drinking container lid that requires less force to release and open, making it easier for users to use a drinking container, "on the fly." An even further objective of my invention is to provide a Drinking container lid that can be easily disassembled for cleaning DESCRIPTION OF THE INVENTION In accordance with the above objects and advantages, the drinking container lid includes a pivotally mounted drinking spout which is manually pivoted, rotated about a pivot hinge in the base of the lid, moving between an open position, with the spout vertically and a closed position, with the spout oriented horizontally on the upper side of the base of the cap.The spout includes an extended portion, the lower spigot portion, which is located on the outer side of the base of the lid, with the tap to drink pivoted to the closed position on the surface lat In the upper part, the lower spout portion pivots simultaneously towards the surface of the lower side of the base of the lid. The lower spigot portion is connected to an elastic tube, a portion of which sleeves the lower spigot portion and the remainder extends from the lower spigot portion for liquid immersion into a bottle to which the cap is connected. With the tap to drink open, a user can suck liquid through the mouthpiece, aided by a passage of ventilation also contained in the base of the lid. When the spout is pivoted to the closed position, the lower spigot portion rotates the elastic tube and presses a portion of the elastic tube over the ventilation passage and simultaneously presses closing another portion of the elastic tube, thereby sealing the cap.

With a single action, the openings in the lid close.

With both openings of the lid closed, the confined liquid can not leak or escape from the bottle, nor can external contaminants enter. Suitably, the drinking container includes a diaphragm that allows the drinking spout to pivot and a releasable latch to lock the drinking spout in the closed position. According to another feature of the invention, except for the elastic tube, all the above elements are conveniently an integral structure formed of a piece of plastic material, suitably polypropylene. As an advantage, the preferred embodiment contains only two components, the elastic tube and the lid, the latter containing the integrally formed diaphragm and spigot. The components can be easily separated and washed. The lid can be washed in the upper rack of a dishwasher and the elastic tube can be washed by dragging completely and cleaned. Reassembly is simple and does not require tools or special training. The above and further objects and advantages of the invention together with the characteristic structure thereof, which was only briefly summarized in the above passages, become more apparent to those skilled in the specialty upon reading the detailed description of a preferred embodiment. , which follows in this specification, taken in conjunction with its illustration presented in the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS In the drawings: Figure 1 is a front perspective view of a preferred embodiment of the lid to the drinking vessel illustrated in the closed condition; Figure 2 is a form of a drinking container containing a drinking container lid of Figure 1, illustrated in the open condition and an associated bottle, partially illustrated; Figure 3 is a top view of the drinking container lid of Figure 2; Figure 4 is a front partial sectional view of Figure 1, illustrating the integrally formed bolt; Figure 5 is a side sectional view of the drinking container lid, as illustrated in Figure 2; and Figure 6 is a side sectional view of the drinking container lid in the closed condition as illustrated in Figure 1. MODES FOR CARRYING OUT THE INVENTION Concurrent reference is made to Figure 1, which illustrates my lid. drinking vessel 1 in a closed position and to Figure 2 which illustrates the above elements in an open position, and in dotted lines, the associated liquid container 2, which with the front cover forms a drinking vessel. As illustrated in Figure 1, the lid includes a pivotable drinking spout 3, a diaphragm 4, a hinge 5, a ventilation passage 6, located behind the lower end or base of the spout 3, all formed from a base of top. In the illustrated embodiment, the lid base is formed of a relatively planar upper surface 15a, located on the upper part of the cylindrical wall 7b and a cylindrical wall collar 7c slightly larger in diameter than and supporting the wall 7b. The previous configuration of the cover base is preferred, although as those skilled in the art will recognize from the study of this specification, in other modalities alternate geometries may be employed. As illustrated in Figure 2, the lid 1 is connected to the upper part of the container 2, a bottle. Since the lid for drinking is intended to be used with any glass or plastic bottle with a top thread, the details of which are not necessary for an understanding of the invention, the bottle does not need to be further illustrated or described. An elastic tube 8 subsequently more fully described here is illustrated partially extending from the underside of the drinking lid 1 and in the bottom region of this bottle. In Figure 1, the drinking spout 3 is illustrated in its closed position, extending horizontally, pivoted downward in a U-shaped recess in the cap base extending radially through the side. The spout extends slightly beyond the side wall to the base of the lid, allowing a projecting portion for the user to grasp or push in order to release and pivot the spout upward to the open position. In Figure 2, the drinking spout 3 is illustrated in the open position, where the drinking spout is vertical. The drinking spout is connected to the hinge 5, as discussed hereinafter in greater detail. The hinge is an active hinge formed integrally on the upper surface of the lid base. This hinge defines the pivot axis on which the spigot is driven, or more appropriately rotates, between the open and closed positions of the spigot and vice versa. As in my previous U.S. patent. Do not. ,392,968, the pivotable movement of the drinking spout 2 is possible due to the function of the diaphragm 4, which is connected both to the spout 3 and to the supporting surfaces of the more rigid lid base. The deflection of the diaphragm allows the drinking spout to pivot and maintain the continuity of the surfaces of the lid in front of this movement of the spout. As described hereinafter, the spout 3, when in the open position, together with an elastic tube 8 forms a straw through which the user can suck liquid from the bottle 2. A ventilation passage 6 extends through the upper surface 7a and serves as a ventilation for air. When suctioning at the end of the spout to drink 3 to extract liquid, ventilation allows external air to pass inside the confined region on the underside of the base of the cap and the confined liquid of the bottle 2 which helps to suck the liquid Preference is given in Figure 3 illustrating the embodiment in a top view with the drinking spout 3 in the open condition as in Figure 2. The complete expansion of the diaphragm 4 is visible in this view. The diaphragm 4 consists of an upper portion 4c which is relatively rigid, a upper flexible portion 4a and a lower flexible portion 4b. A semicircular region recessed from the planar upper surface 7a at the base of the lid is bordered on one side by a dependent circular wall 9 only partially visible in Figures 1 and 2, to which the diaphragm 4 is connected. The diaphragm is essentially it serves as part of the edge or surface to that recess. The circular wall 9 extends in a semicircle with respect to the base end of the spout and is symmetrical with it. The length of the wall varies and is determined by the downward inclination of the diaphragm 4; the wall only needs to be deep enough to reach and connect the outer edges of the diaphragm 4. The depth of this wall varies from a maximum to the center to a minimum at each end at the hinge 5. The circular wall 9 is relatively rigid and provides a Firm support for the diaphragm. At the same time, the junction between the diaphragm and this wall allows the diaphragm to be sectioned in the manner described in the Dark '968 patent during the operation of opening and closing the spigot.

The upper planar surface 7a is also interrupted by a portion with a U-shaped wall recess , recessed from the upper planar surface, and forms a passage or channel from the aforementioned recessed region both through the dependent circular wall 9 as the outer cylindrical wall 7b. The U-shaped region allows it to pivot to the spout and to remain in a horizontal position as illustrated when closing. The U-shaped recess 10 extends radially in line with the plane of rotation of the spout 2, represented by the line 11, and is sufficiently wide and deep to receive the spout. As illustrated, that plane of rotation extends through the axis of the spout 3, ventilation passage 6 and illustrates with hidden lines, an interference rib 12, the latter being located on the underside of the upper surface of the cover 7a. The outer edges of the lower flexible diaphragm portion 4b are connected to the semicircular wall 9. The upper diaphragm portion 4c, specifically two triangular-shaped portions, which are integral with the folding and flexible portion 4a of the diaphragm, subsequently described in more complete, one of which is located on each side of the drinking spout 3. The upper diaphragm portions of triangular shape, constituted with a greater thickness of material and relatively small in size than the portions of diaphragm 4a and 4b, are relatively rigid, with respect to those other portions of diaphragm. The upper portion 4c connects to the lid base on the hinge 5 and also connects to the spout 3. As illustrated the diaphragm 4 also serves as a fluid barrier. The only passages through the cap are the passage of fluid through the spout 3 and the ventilation passage 7. A pair of axially extending splines 15 are located in diametrically opposite positions in the outer tubular wall at the front end from spigot to drink 2. These splines project radially outward to the sides, a short extension. A pair of elongated tines 16, formed in the opposite side walls in the U-shaped region 10, together with grooves 15, form a releasable latch that holds the spout 3 in the closed position illustrated in Figure 1, until it manually released by the user by pushing up the far end of the spout. Returning to Figure 2, the grooves 15 only one of which is completely visible in this view extend axially over the length of the spout. The length of the grooves is sufficient to couple the molded tines 16 into the side walls of the U-shaped recess 10, when the spout is pivoted downwards.

Reference is made to Figure 4, which is a partial front section view of Figure 1, and illustrates better the position of the bolt member when the spigot is locked. As illustrated, the upper surface of each tine 16 tapers down a short vertical distance, forming a cam surface and then falling horizontally. The ends of the splines 15 in the spout are spaced horizontally at a distance greater than the distance between the inclined portions of these tines, but spaced the same distance as the ends of the horizontal portion of these tines located in the support walls. To close the spigot 3, the user presses down the spout to force it in its closed and locked position. When pivoting down to close, the grooves 15 encounter the cam or inclined surface of the tines 16 that initially provide an obstruction. The downward force exerted by the user must be sufficient to flex outwards the side walls of the U-shaped lid portion 10 which hold the tines 16 and / or through grooves inwards resiliently compressing the spout, in order to move the Spit down, beyond the horizontal position of the tines 16 and lock it in place. Once the ridges 15 have moved beyond the tapered portion of the tines, the flexed surfaces spring back to their original shape and the tines superimpose the ridges. The splines 15 trap and are supported by the horizontally oriented surface of the tines 16, which now holds the spout down against any upward force that can be exerted resiliently on the diaphragm 3 and subsequently as described herein, by the elastic force in the tube 8. Referring now to the sectional view of Figure 5, the drinking lid 1 is essentially seen as a hollow body, formed of relatively thin walls that provide a cavity region on the underside of the surface upper 7a, limited by the cylindrical walls 7b and 7c, the diaphragm and the spigot. An edge of the vertical circular wall 9 to the recessed region is visible in this view. The height of the circular wall 9 at any angular position with respect to the axis of the spout 3 varies with the location of the position of the outer edge of the diaphragm portion 4b, which extends upward at a steep angle with respect to the horizontal surface 7a . The ventilation passage 6 is displaced radially in position from the axis of the spout 3 and from the pivot axis at the hinge 5. The underside of the ventilation passage also preferably is surrounded by a seal 14, formed as a circular projecting portion. on the underside of the lid surface 7a. The interference rib 12 is formed integral with the underside of the horizontal planar surface of the closure 7a and is positioned a greater distance away from the axis of the spout 3 and the hinge 5, and is placed on a radial line 11, illustrated in FIG. Figure 3, which intersects both the axis of the spout and the ventilation passage 6. The interference rib 12, conveniently, extends downwardly in the region of the underside to provide a radially inward inclined surface, oriented at an angle with respect to the vertical, between about 5 and 10 ° in a practical embodiment, angled towards and with respect to the spout 3. As described hereinafter, the slight angle allows the interference rib to serve a second interlocking function of spigot in combination with the elastic tube 8. Continuing with Figure 5, the spigot for drinking 3 contains an integral extension or as a portion was variously termed a portion bottom spout 3b located on the underside of the diaphragm 4 below the top surface 7a to complete the passage of fluid through the spout, from the top side of the lid base to the bottom side. The leg end of the lower spigot portion supports a retainer ring 17, an enlarged outer diameter portion or ring projecting radially outwardly from the tubular wall of the spout. In this mode, the lower spigot portion 3b is of a restricted outer diameter with respect to the upper portion. The length of the lower spigot portion is large enough to extend at least by the radial distance to the ventilation passage 6, when the spout 3 is pivoted relative to the hinge 5 to the closed position, but not so large in length to contact the interference rib 12. The elastic tube 8 fits over and sleeves this lower spigot portion, frictionally coupling the outer cylindrical wall of the lower portion and is held in place in this spigot portion by the frictional force of the retaining ring 17, which elastically expands a small portion of the tube wall. The remaining portion of the elastic tube is suspended from the spout. The elastic tube, only partially illustrated in the Figure, is of sufficient length to extend to the bottom region of the associated bottle and, like a straw, is intended to be submerged within any liquid confined in this bottle when the spout is in the position open When the spout 3 is pivoted to the closed position, as illustrated in the sectional view of the Figure 6 to which reference is made below, the lower end of the spout rotates the elastic tube 8 upwards against the lower side of the upper surface of the closure 7a, pressing the elastic material of the tube against the seal 14 on the underside of that surface and covering the ventilation passage 6. It also presses another portion of this elastic tube against the interference rib 12, producing an elbow in the tube, and crushing the walls of the tube between the end of the leg of the spigot portion lower and the confronting surface of the interference rib. Tube walls crushed or "twisted" in this way block the passage of fluid through the tube. As noted previously, the interference rib 12 is tilted at an angle of 5 to 10 ° from to the vertical (or 90 to 95 ° with respect to the horizontal) towards the spigot. The angle creates a second latch method that aids the elastic tube 8 to remain in a sealed position when the spout is in the closed position. As the spout 3 is pivoted to the sealed position, shown in Figure 6, the elastic tube first engages the lower end of the interference rib 12. With the user exerting downward force on the spout, a portion of this tube, located by under the end of the extension of the tube 3b, it compresses beyond the rib, temporarily compressing the tube in this portion. As this portion moves upwardly relative to the end of the interference rib in a laterally wider region near the underside of the upper surface 7a, the portion expands resiliently in a slight manner, as the other portion of the tube engages the seal of ventilation. This expansion allows the resilient force of the tube walls to assist in holding the bottom end of the spout in the horizontal, closed position illustrated in the Figures. To move the end of the spout out of the closed position, in this way, the force must be sufficient to recompress that portion of the elastic tube. By contributing to the interlocking function in the above manner, it is possible to reduce the resistance of the previously described bolt at the front end of the spigot. The portion of the elastic tube 8 that seals the air vent is held by the rigid walls of the lower spigot portion, while the portion of the tube conveyed in the elbow is a suspended portion. It is noted that the leg end of the lower spigot portion is sufficiently distant from the interference rib 12, such that the KI1 is preferably placed slightly below the leg end when the spigot is pivoted downwardly as illustrated . That location minimizes the force needed to pivot the spout down and keep it locked in place. Again reference is made to Figure 5. The diaphragm 4 is preferably a composite diaphragm described in the Dark 968 patent to which reference can be made for a more detailed description and which is incorporated herein by reference. Essentially the diaphragm is formed of two types of diaphragm that are connected in series as a whole enters the base cap and spigot 3, comprising an invertible diaphragm 4a and a flexible collapsible diaphragm 4b the edges of which are illustrated in the Figure. In the specific embodiment illustrated in that prior patent, a bi-plane sector is illustrated oriented at an angle of 45 ° to the plane of the planar top surface of the lid base, such as the horizontal plane of the top surface 7a, illustrated in Figure 5. The plan line 18 represents a bisector plane in the drinking lid 1 which contains the edge of the diaphragm 4 and extends through the hinge 5. In the present invention, this angle between the bi-sector plane 18 and the horizontal becomes shallower, specifically 45 °. When the spout 3 is turned from the vertical open position to the closed position, the spout pushes the flexible diaphragm 4 which in turn pushes or rotates the invertible diaphragm 4a down through the bi-sector plane. With the 45 ° angle, the invertible diaphragm component 4a of the composite diaphragm is inverted, ie it passes through the top dead center position 1, the bi-sector plane 18, but does not reverse completely, as in the case of design shown in the Dark patent '968, where the angle at 45 ° is employed, before a folding action of the foldable diaphragm component 4b occurs. The description of the movement of the diaphragm during the closure and opening of the spout is suitably described in the prior Dark '968 patent, which is incorporated herein by reference and will not be repeated. With full inversion of the invertible diaphragm, it was found that a residual propensity occurs slightly for the diaphragm to pull up slightly, pivoting the spout back by up to 5 ° of arc, from the position where the spout is closed, considering that it is removed or deactivates the spigot lock. This residual force appears to be due to the fact that the polypropylene material of which the diaphragm is preferably constructed, unlike rubber, does not "relax" completely in the inverted position, and the diaphragm material is distorted on the outer edges. This return or spring force is small and much smaller than the force required to move the diaphragm back through the position of the top dead center 1 of the invertible plane. For the most part, the residual spring force of the invertible diaphragm is of little or no consideration, since the latch on the closing spigot keeps the spout down tightly sealed and accordingly the diaphragm is connected. Due to the nature of the use of a sports drinking bottle, however, it is desired to make the drinking bottle as easy to open as possible. To achieve this facility, a bolt must be designed so that the spigot is less strong than in the previous closures of the Dark '968 patent. Since the bolts 15 and 16 must handle the described residual spring or elastic force created by the reversal of the diaphragm, the stated problem was to reduce or deviate that force. The present invention accomplishes this by reducing the diaphragm angle from 45 ° to 40 °. This change is found to reduce the spring force to a lower level. The invertible diaphragm portion is no longer required to fully reverse when the spout is sealed closed.

The spigot lock can now be of a weaker design and therefore easier to release. As illustrated in Figure 5, the drinking spout 3 is connected to the diaphragm 4 by a connecting portion in a position slightly above the horizontal surface 7a of the lid base to allow the drinking spout to rotate with respect to the pivot of the spout. hinge 5. The lower spigot portion of smaller diameter 3b therefore extends to a position slightly above the surface 7a. This allows the diaphragm 4 to be slightly larger in size, which makes it easier to pivot the spout between its open and closed positions. As illustrated in Figures 5 and 6, the cylindrical wall 7c serves as a collar for connecting the drinking lid 1 to the bottle 12. The inner side of this wall is provided with a suitable threaded head 20 molded into the wall to connect the lid for drinking into the bottle container with thread 2, previously illustrated in Figure 2, and a flexible ring 21 that extends from an inner cylindrical wall and is integral with it. This ring is directed radially inward and is inclined downward and oriented to engage the upper edge of the associated drinking bottle and serves as a seal for liquid. It is recognized that other configurations of the conventional side wall can be substituted to fill the lid are the bottle, everything sual sae inside the alsanse of my invention. As those are dexterity in the specificity of the view in lateral session of Figure 5, all the previous elements of the lid of drinking filler, except the elastic tube 10, can be molded from a piece of plastic material, suitably polypropylene, as an example, in the form dessrita in the patent Dark 968 and forms a estrustura of an integral unitary piece. Preferably, the elastic tube 8 is formed of rubber. Less preferred embodiments use the tube formed of polypropylene material. However, polypropylene yields elastically, a disadvantage, while rubber is easier to stretch and repeatedly squeeze, which is preferable. The above provides a lid for drinking container, leak proof, which is easy to open and close. It is formed only of two somponent pieces that are assembled easily in sonjunto. It is easy to disassemble and employ. It is only necessary to remove the lid of the bottle and open the spout, remove the elastic tube 8, which is only held frissionally in place. The lid can be washed by hand or on the upper shelf of a dishwasher, and the tube can be washed by dragging and cleaning, without leaving traces of any drink. The bottle can be cleaned separately. The reassembly is equally simple. The end of the elastic tube 8 is simply forced into the lower spigot portion 3b, elastically expanding the tube end over the ring 17. As is apparent, no special tools or training is required. It is considered that the previous breakdown of the preferred embodiments of the invention is sufficient in detail to enable a person to be skilled in the art of making and using the invention. However, it is expressly understood that the details of the elements presented for the above purpose are not intended to limit the scope of the invention, since so many equivalents are those elements and other modifications all the suals are within the alsanse of the invention, will be Apparent to those are skill in the specialty before reading this specifisasión. In this way, the invention will have to be considered widely within the whole alsanse of the associated claims.
