Description

  This application is a non-provisional US patent application Ser. No. 12 / 422,598, filed Apr. 13, 2009, US Provisional Patent Application No. 61 / 124,244, filed Apr. 15, 2008, and Claims priority based on US Provisional Application No. 61 / 156,523, filed Mar. 1, 2009, all of which are incorporated herein by reference.

  The present invention relates to a drinking straw, and more particularly to a drinking straw with a safety function that prevents easy withdrawal from a beverage container.

  As is generally known, a drinking straw is a cylindrical tube having two open ends. One end is placed in a beverage and the other end is placed in a person's mouth. By exerting suction through the straw, a small amount of the beverage is sucked through the straw into the person's mouth. Because the straw allows a person to drink without having to lift the entire cup, the straw is often provided to children who may have difficulty drinking from the cup or glass without spilling the contents.

  For the same reason, children's drinking cups often have a removable lid to help prevent large spills. These lids generally have an opening through which a drinking straw can be inserted.

  It is also common for children to drink from a carton or pouch with a liquid that provides a single dose of non-carbonated beverages such as juice or milk. These containers are commonly referred to as juice boxes or juice pouches. (Hereinafter, the phrase “juice box” is used to refer to any kind of single-dose beverage container designed to be consumed with an attached straw.) Generally, it is packed with a straw for drinking. The straw is typically attached to a juice box and is removable therefrom. The attached straw generally has a diagonally cut piercing end, while a straight cut spout has the other hard end. The piercing end is designed to pierce the beverage container through, for example, an opening sealed with a small piece of metal placed near the tip of the juice box.

  The drinking lid and juice box configuration helps to prevent large spills, but parents are encouraged to draw drinking straws from drink containers when a small child is inappropriate, and on the table or floor. Often struggles to prevent spilling drink liquids or throwing straws. The result is a messy condition that must be cleaned and / or the straw becomes dirty and can no longer be reused for the intended purpose. In addition, the child may lose the straw and not be able to drink any more. Moreover, because the straw can no longer be used, having to get a new clean one and use it is detrimental to the environment.

  U.S. Pat.No. 5,897,013 awarded to Manganello's "Straw for Drinking Cup" is that a straw is inserted through the opening of the lid from below, and the retaining shoulder is only a predetermined length of A reusable straw and lid assembly is taught that allows it to extend above the lid. The instrument taught by Manganello is not designed for disposable use. This instrument is too complex and difficult to manufacture suitable for one-time use. Moreover, the straw and lid are a complete assembly designed to work together. The straw would not be suitable for use on other lids, such as a typical disposable lid placed on a drink in a fast food restaurant. Finally, Manganello straws must be inserted from the underside of the lid, making it more difficult to use for drinking lids and impossible to use with juice boxes and the like.

  U.S. Pat. No. 5,114,074 to Frauthal et al. "Retraction Resistance Straw" describes a straw with a radially extending flexible retention tab secured to the outside of the straw. However, in order to insert the straw into the opening, the tab must first be wrapped around the straw to allow the straw to pass through the opening in the lid or juice box. Frauenthal is also formed with a truncated cone that goes up to the middle of the length of the straw, with the base of the cone (which is much larger in diameter than the straw) facing the tip of the straw Alternative embodiments are described. However, both of these embodiments may be difficult to use and manufacture. The tab embodiment requires wrapping the tab around the straw before insertion into the user. This is clearly difficult for adults and almost impossible for small children. The conical embodiment, as shown in Frauenthal, creates a larger hole in the lid or juice container, requires additional effort to insert the straw, and increases the possibility of leaking or spilling around the straw. The same is true for tab embodiments, particularly for metal flakes on beverage boxes or pouches, as the tabs tend to cut through the metal flakes unless they are pre-folded against the straw. I will. Finally, both embodiments are difficult and expensive to manufacture and cannot be made using common extrusions currently used for drinking straw production.

  Accordingly, there is a need for a straw designed to prevent easy withdrawal from a beverage container. Finally, there is a need for a drinking straw that is inexpensive and sufficiently easy to manufacture so that it can be used as a free, disposable article.

US Patent Application No. 12 / 422,598 US Provisional Patent Application No. 61 / 124,244 US Provisional Patent Application No. 61 / 156,523 US Pat. No. 5,897,013 US Pat. No. 5,114,074

  The object of the present invention is to provide a solution to the disadvantages of the prior art.

  It is an object of the present invention to provide a drinking straw assembly that can be easily inserted through a lid or into a beverage pouch or box, but cannot be easily removed by a child once the straw has been worn. Preferred embodiments are also inexpensive to manufacture so that the product is suitable for use as a single use disposable straw.

  The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. This summary of the invention does not enumerate all the necessary features, and thus a sub-combination of those features can also constitute an invention. Additional features and advantages of the present invention are described below.

  The attached drawings are not shown to scale. In the drawings, each identical or nearly identical component that is illustrated in various figures is represented by a like numeral. For clarity, not all components in all drawings are labeled.

  Preferred embodiments of the present invention provide a drinking straw that can be easily inserted through a lid or into a beverage pouch or box, but cannot be easily removed by a child after the straw has been properly inserted, for example. “Easy to insert” means that the required force is relatively small but not zero. The drinking straw according to the present invention must be able to be inserted through the lid or into the beverage pouch or box using substantially the same force required by prior art straws. Once inserted, the straw according to the present invention is not easily removable, as will be explained below. This means that the force required to remove the straw according to the present invention is substantially greater than the force required to remove the prior art straw. Due to the relatively fragile materials commonly used in beverage lid construction and the preferred materials used for the preferred embodiments of the present invention, if you are an adult, you can use a drinking straw according to the present invention, for example The beverage lid material or drinking straw should be able to be removed reliably by pulling it strong enough to pull it apart. However, in normal use, the drinking straw according to the present invention should be difficult to remove, especially for children, after being inserted through the lid or opening of the beverage container.

  If it passes in one direction through a hole in the lid or juice box, it follows the straw closely, but if the straw is pulled in the opposite direction, the beverage container lid, juice box, or This is accomplished by various types of retention extensions attached to or integral with the straw that may catch on other beverage containers. As used herein, the term “integral” is used to mean that the straw and extension are formed as one piece, rather than glued or attached to the straw. Is done. In the embodiments described herein, these extensions can be viewed as a type of “straw holder” that will hold the straw in place. Preferred embodiments are also inexpensive to manufacture so that the product is suitable for use as a single use, disposable straw.

  Since the preferred methods or devices of the present invention have many new aspects and the present invention can be implemented in different methods or devices for different purposes, not all aspects need be present in all embodiments. Furthermore, many of the aspects of the described embodiments are patented separately. Although most of this description is made on drinking straws for use by children, the preferred embodiment will also be suitable for use by the elderly or disabled. Also, the drinking straws according to the present invention can be used in zoos or parks where discarded straws can be dangerous for animals or wildlife. Still further, the drinking straw according to the present invention can generally be used ubiquitously as an aid in preventing scattering. Preferred embodiments of the present invention can also be used to simply prevent the straw from being accidentally removed or pulled out.

  A preferred embodiment of a drinking straw assembly 10 according to the present invention is shown in FIG. The straw 11 can be manufactured by any known appropriate method including an extrusion molding machine normally used in drinking straw production. For example, straws with diameters typically used in fast food restaurants (typically 15 mm or less) and straws with diameters suitable for use in commercial juice boxes (typically 3 to 6 mm) Can be used. The straw 11 can be formed from any suitable material as is known in the art, including, for example, polypropylene resin. In some embodiments, the straw has an obliquely cut lower end for piercing through a metal foil sealed opening of some beverage containers, while a straight cut drinking end. The state may have an upper end.

  The sleeve 12 is attached around the outside of the straw 11. The sleeve can also be formed using an injection molding machine to make a cylindrically shaped sleeve with a sufficiently large inner diameter so that the sleeve fits around the outside of the straw. The sleeve 12 is preferably formed from the same material as the straw 11. The plurality of finger-like extensions 14 press tightly against the straw when passed in one direction through a hole in the lid or juice box, but when the straw is pulled in the opposite direction, the lid or You will get caught in the juice box. As shown in FIGS. 1A-3B, the distal or upper end of the extension has a tip diameter 16 (including the space between the extensions) from end to end of the extension, but the extension attaches to the sleeve base. Preferably, it tends to spread away from the straw so that it is larger and wider at the upper end than the lower end diameter 17 being joined or joined.

  The extension is preferably integral with the sleeve. That is, the sleeve and the extension are preferably formed from one solid part material. As shown in FIG. 2, the extended portion 14 can be easily formed by forming a plurality of longitudinal slits in the cylindrical sleeve 12. In some preferred embodiments, the extension can curl away from the outside of the straw, as shown in FIG. 1A. For example, the curl of the extension can be formed by holding the extension in a curled desired shape and applying heat. The extent to which the upper portion of the extension is unfolded away from the straw is sufficient to “stuck” the bottom of the beverage container metal flake or lid when the straw and sleeve are pulled back up through the opening. It can be changed within a wide range. In addition to the finger shape shown, the extension can be formed in any desired shape, such as, for example, a tab having a width greater than the height or a triangular shaped extension.

  The sleeve 12 is attached around the straw and held in place, for example, by friction, heating to the assembled sleeve and straw, adhesive, ultrasonic welding, and the like. The slit should be long enough to be a sufficiently large extension to prevent it from being easily removed from the beverage container after inserting the drinking straw, but the sleeve becomes weak or the sleeve is pre-determined. It should not be extended so as to significantly reduce the holding force in position. The sleeve itself may also be of any desired overall length (including the length of the extension), for example, 3/4 to 1 and 1/2 inch overall length. When the straw is fully inserted into the beverage container (ie, when the straw is inserted to a depth that can be used to draw the beverage out of the container), the sleeve opens the lid or container opening. It should be held in place in the longitudinal direction on the straw so that it passes completely. For a typical drinking straw suitable for use in various containers, the lower end of the sleeve can be placed no more than 3 inches (7.62 cm) from the lower end of the straw, for example. More preferably, the lower end of the sleeve is placed 1 to 2 inches (2.54 to 5.08 cm) from the lower end of the straw. Most preferably, the lower end of the sleeve is positioned about 1 and 1/2 inches (3.81 cm) from the lower end of the straw. This will allow the straw to be used for short containers (such as yogurt cups). For taller containers (typical disposable drinking cups), the straw can be pulled up a few inches from the lower end of the cup until the sleeve extension catches on the lid or container.

  As described below, in some preferred embodiments, the extension can be attached directly to the straw or can be formed integrally with the straw, but the extension 14 is preferably more than the straw 11. Rather, it is attached to the sleeve 12. Further, as shown in FIG. 3A, the extensions 14 are preferably attached to or connected to the sleeve only at the base of each extension (the proximal end of the extension). The locking or transition between the sleeve and the extension indicated by the dotted line 32 is preferably when the extension is pressed upward against the lid of the drink container, as shown in FIG. Positioned in a plane that is substantially perpendicular to the long axis 19 of the drinking straw (and thus parallel to the lid of a typical drink container when the straw is inserted) so that it presses tightly against the underside of the lid. Will be.

  In a preferred embodiment of the present invention, only the longitudinal force pushing the drinking straw through the opening will press each extension snugly against the straw. That is, the straws and sleeves of the present invention can be inserted straight into a typical beverage container or lid, just like prior art straws, without twisting or requiring special movement.

  Alternatively, the extensions can be attached to the sleeve at the lower end of each extension, or can be connected to the sleeve and attached integrally at the tip of the extension, but towards the central portion of the extension Separated from the straw and spread apart. In this preferred embodiment, the sleeve and extension would rather function like a standard wall fixture.

  FIGS. 4-7 illustrate the steps of inserting a drinking straw into a standard beverage lid 42. The lower end 44 of the drinking straw (the end opposite the extension 14) is first passed down through the opening 46 from the upper surface 48 of the lid. As the drinking straw 10 passes through the opening 46, the downward force closely presses the expansion 14 against the straw 11, thus passing through the opening 46. However, the distal end of the extension (the free end opposite the sleeve or away from the sleeve), after passing through the opening, widens away from the straw body as shown in FIG. Will be. Any attempt to pull the straw out of the opening will result in the end of the extension contacting the lid or portion of the juice box that surrounds the opening. Thus, as shown in FIG. 7, the extension is spread out, which prevents the drinking straw from being easily pulled back through the opening. In a preferred embodiment, when the straw is pulled outward, the extension itself will be wide enough to provide sufficient resistance. In the preferred embodiment of FIG. 7, the overall width of the extension that is pressed against the lower surface of the lid (not including the space between the extensions) is approximately equal to the diameter of the straw.

  Preferred embodiments of the present invention can be applied to any size straw and can be used with any commercially available juice box or pouch. Embodiments of the present invention can be used with beverage container openings that are only slightly larger than the diameter of the drinking straw and sleeve. Embodiments of the present invention because the extension tends to spread away from the straw if no force is applied, and because if the attempt is made to remove the straw, the extension extends much larger than the diameter. Can also be used with an opening substantially larger than the diameter of the drinking straw and sleeve. Thus, the present invention is not limited to beverage containers with standard insertion holes.

  The preferred embodiments of the present invention can be used in any common beverage container, including Hi-C®, Yoplat® yogurt, Coca-Cola® product, Dr. It can be used for any beverage or liquid, such as Pepper® products, and any other soft drink. Preferred embodiments of the present invention can be used with drink containers that are purchased at restaurants with lids or drink containers that are used at home with lids or lid-like equipment. A drinking straw according to the present invention may be a single use, disposable item or may be reusable. The drinking straws according to the present invention can be provided with drink containers, such as straws generally packed with juice boxes and pouches, or individual drinking straw boxes that can be used with any desired beverage container, for example. Or can be provided individually by packing.

  In another preferred embodiment, the sleeve according to the invention can be reusable and not disposable. For example, a reusable sleeve arrangement can be provided so that the inner diameter of the sleeve fits tightly over the outside of various standard straw dimensions. The inner diameter of the sleeve will preferably fit tightly over the outside of a standard straw so that the sleeve is held in place by friction. Even if sufficient force is applied and the reusable sleeve slides over the outside of the straw, the friction between the straw and the sleeve is preferably, for example, that the child pulls the straw or the straw from the beverage. If it is attempted to remove the straw, it will be sufficient to provide adequate resistance to prevent easy withdrawal of the straw.

  In some embodiments, the straw can be formed with one or more indentations or one or more thicker areas to facilitate placement and attachment of the sleeve. In another preferred embodiment of the invention, the straw and the at least one extension can be formed as a single component, preferably in an extrusion process. For example, FIGS. 8A and 8B show a straw assembly 20 in which a plurality of extensions 14 are integral with the straw 11. FIG. 8B is a cross-sectional view showing that the extended portion 14 and the straw 11 are formed as an integral part. Those skilled in the art will appreciate that different numbers of extensions and different forms of extensions can be formed without departing from the spirit and scope of the present invention.

  Instead of the finger-like extensions described above, one or more generally conical extensions can also be formed. For example, FIG. 9 shows a straw that includes a straw shaft 60 and a straw holder 62 that are also formed as a single piece (as in the embodiment shown in FIG. 8). The straw holder 62 is basically a thin conical material extending from the straw shaft 60. The straw holder 62 can be formed, for example, such that the straw is extruded by pressing the material into a conical mold. The straw holder 62 is sufficiently flexible so that it can be inserted into the beverage container while pressed against the straw shaft 60. The conical portion has one or more slits substantially parallel to the longitudinal axis of the straw shaft 60 so that the conical portion is easily pressed when inserted into the beverage container. Can do.
