This invention relates generally to drinking straws and, in particular, to straws with bulges or hips that enable the straw to engage with other articles.
There are many novelty drinking straws made and sold every year. These novelty drinking straws include drinking passages which are in the form of loops, spirals, flowers, stick figures, eye glasses, etc. Some examples of patents disclosing such novelty drinking straws include: U.S. Pat. Nos. 2,063,803; 2,557,411; 2,619,770; 3,260,462; 3,326,695; 3,425,626; 3,517,884; 3,606,156; 3,773,256; 3,957,202; 4,374,596; 4,687,306; 4,699,319; 4,828,355; and 5,184,774. Such novelty drinking straws are intended to amuse the users (principally children) by attracting their attention to the visual display made when fluid passes through the drinking tube as the straw is used.
Novelty drinking straws are also known which include a panel for displaying a message such as an advertisement. In particular, U.S. Pat. No. 4,726,518 discloses such a novelty straw. The straw disclosed in the '518 patent is of a particular construction including a panel having two opposed, flat major faces for the display of indicia thereon, a plurality of channels extending between the major faces and having open ends at opposite sides of the panels, and at least one mouthpiece and one liquid pick-up region formed at the ends of the straw and interconnected by at least two of the panels. As disclosed in the patent, the channels extend linearly up and down from the panel to form the mouthpiece and liquid pick-up region. While this device discloses a flat surface for conveying messages, the device contains many elements that make it unattractive for inexpensive mass production. First, the device relies upon a plurality of channels or conduits in order to pass the liquid. Thus, it is more expensive to manufacture than conventional drinking straws, which have only one channel, and is not easily adaptable to conventional drinking cup covers that are adapted for conventional drinking straws.
What is needed is a novelty drinking straw on which advertising or amusement material may be displayed, which has a single drinking passage. What is further needed is such a novelty drinking straw which is easy and inexpensive to manufacture. Additionally it would be particularly advantageous if such a drinking straw included the ability to remove and replace the inserts.
This invention resides in a drinking straw adapted to engage with an article as well as straw/article combinations, including signage systems. The drinking straw itself comprises an elongated cylindrical plastic tube having an outer wall. The outer wall defines a circular cross section having a consistent diameter with the exception of at least one locally deformed region along the length of the tube wherein, in the locally deformed region, the tube bulges outwardly beyond the outer wall of the tube. This allows the straw to be passed through an article having a hole slightly larger than the diameter of the tube but smaller than the bulged region to cooperate with, engage, retain or capture an article or articles.
In one embodiment the article is the cap of a drinking cup. In another embodiment the article is a sign with opposing holes to cooperate with spaced-apart bulges on the straw. A further embodiment includes an inventive straw, a drinking vessel with an aperture cap, and a sign or other article supported on the straw above the vessel. In all embodiments, each deformed region is formed only by heating the plastic tube such that no additional material is added to, or subtracted from, the straw.
This invention relates to drinking straws specially adapted for use with cups and like beverage containers and formed as a substantially circular tube, preferably of a thermoelastic plastic. Its novelty lies in several aspects. Primarily, it is formed with one or more, and preferably two, lateral bulges formed at spaced intervals toward the upper, or what will be termed the proximal, end of the tube. This location along the length of the straw will be such as to protrude outwardly, above the cap of a cup or other beverage container, when the lower or distal end of the straw is near the bottom of the container and the tube extends through an aperture in the cap.
In the accompanying drawings,
The bulges will extend beyond the normal diameter 110 of the outside wall of the straw so that a suitable article having a central hole may be gently forced over a bulge for capture purposes. That is, with articles having holes that are slightly greater than the diameter of the outer, cylindrical wall of the straw, such articles may be slid over the straw, or the straw may be pushed through articles, with a momentary ‘click’ or ‘snap’ of the deformation through the hole without any damage to the straw or the article. Note that the outermost dimension of each deformed, bulged region is preferably slightly greater than the hole(s) in the article to be engaged. For example, dimension 212 is slightly greater than the diameter of holes 208, 210, 214.
An article that is supported on the proximal end of the straw is illustrated in
Note in
The bulges are preferably formed by raising the temperature of the straw at the area to be bulged, and forcing the two sides of the heated area toward one another as shown in
The applied deformation also enables the straws to rest within their packaging with the straws parallel to one another and with adjacent straws rotated by 90° relative to each other so that the outer bulge on one straw rests in the inward depressions in adjacent straws, allowing compact packaging. This is illustrated in
