(54) Title: BEE-STRAW
(57) Abstract:
The invention relates to the manufacture of drinking straws, chiefly for drinking beer, and designed to eliminate frothing and foaming of the beer. A designer cut at the base allows ample liquid passage enough for a mouthful of beer.
 DESCRIPTION
The present invention relates to a drinking straw, herein referred as a "bee-straw”
It is a drinking implement which enhances a better hygienic standards for it is delivered to
reach the customer/user wrapped and in sterile conditions while using in public places such as hotels, bars and other social gatherings. It’s mainly used to drink alcoholic beverages, beers,
 sodas and such other brews. It is easy and enjoyable louse and adds status to the occasion
ensuring there is no direct contact between the user and the public utensil from which the beverage is consumed from.
The bee-straw background art is derived from the normal drinking straw which has for long been used without health and hygienic conditions being considered in that they are not sterilized and are packed in a way that they can get into contact with disease bearing agents.
In the present invention, the bee-straw is made from plastic or any other suitable polymer material by a rotational or any other form of moulding process and has three main parts. These are the mouth piece, the transfer tube and the gripping hook and are most preferably transparent.
The mouthpiece is the part of the bee-straw that sits into the mouth between the lips during drinking. It is made to rest comfortable on the lips for easier and enjoyable sucking The mouthpiece is curved at an angle of 130 degree in a way that the user can take his/her beverage more comfortable-without bending forward.
There's a non-return valve (D) nearer the base of the mouthpiece or either at the bottom or top of the transfer tube which prevents the liquid from going back to the container. This facility
20 prevents the possibility of a user spitting the saliva or sucked juice back in the container in cases where two or more users are drinking from the same container but each with his/her own bee-straw. The possibility of a user contaminating the drink or the transmission of diseases by users is prevented.
The function of the gripping hook is to secure the bee-straw to the container from which the beverage is being taken from. The hook and the mouthpiece are manufactured together, though a combination of the three parts into one unit is as good while manufacturing each part separately and later assembling together is practicable. The hook is incorporated at the curve of the mouthpiece mentioned herein above and prevents the bee-straw from accidental falling off and constant handling. Once the bee-straw in securely held on to the container with the gripping hook, the user places his/her lips on the mouthpiece and sucks on the liquid to once enjoyment without leaning forward or backward to reach the drink, Figure (1) shows the mouthpiece incorporated with the gripping hook.
The transfer tube (hollow section) is manufactured separately and is easily slotted into the mouth piece.

There are grooves (F) Figure 2, on the top of the transfer tube and tongues (E) Figure 1 at the base of the mouthpiece. The grooves and tongues makes the mouthpiece and the transfer tube to be held tightly when slotted in, though any other appropriate combining can be introduced. The transfer tube is made with zig-zags in sections along its length. This facility enables the bee-straw to be used in containers with various depths. The zig-zags can be elongated to enable the bee-straw fit in either a small container/glass or to a bigger container/bottle.
Figure 2: 1 shows a transfer tube with the zig-zags unstretched. This allows the bee-straw to be used with a glass/short container. It gives a total length of 123mm. Figure 2:2 shows a transfer tube with one section of the zig-zags stretched. These zig-zags, when unstretched, are 20mm long. When stretched, the section becomes longer three times e.g. 60mm. The bee-straw therefore is 163mm long. However, the length of the unstretched (20mm) and the stretched (60mm) can vary depending on requirements and also on the lengths of the zig-zag pitches.
Figure 2:3 shows a transfer tube with two sections stretched. This makes the bee-straw length to be 203 mm and can be used on bigger containers. Figure 2:4 shows the transfer-tube with the same zig-zag sections stretched, giving the bee-straw 50 a length of 243mm.
It should be noted here that this zig-zag sections are not limited to only three. They vary according to the user’s needs and manufactures market targets.
It should also be noted that since these transfer-tubes are made of plastic material, when the zig-zag sections are stretched, they do not revert to the original size.
These are specially designed double cuts F2: 1M at the base of the transfer tube. These enable the liquid to move easily up the straw and prevent frothing.
 ABSTRACT
The present invention relates to a drinking straw "Bee-Straw" comprising a mouthpiece, gripping hook and transfer tube, made from plastic or any other suitable polymer material.
The said transfer tube having zig-zag sections which could be stretched to vary the length of the bee-straw to fit in containers of various depth.
The mouth piece or a transfer tube having tongue or a groove respectfully for securing each of the said mouthpiece and tube together tightly
 
CLAIMS
