Definitions

• the present invention relates to a closing device for a bottle.
• beverage containers for example portion packs.
• Bottles are found in various sizes, and with their characteristic design, i.e. a container tapered at the top to an opening to drink from.
• Commonly used materials for bottles are plastic, such as PET, and glass.
• closing device for example bottle caps.
• a bottle cap is manufactured from metal or another material, and is removed with or without the help of a special tool.
• the cap is in general not resealable.
• Another closing device is a screw cap, manufactured from plastic or another material. A screw cap is removed by twisting it off from the opening of the bottle. Thereafter, the same screw cap can be reused in order to reseal the bottle at a later time.
• Non-resealable closing device is a thin foil, manufactured from, for example, metal, which is perforated by for example a straw and then used for drinking the liquid therethrough.
• the foil can also sometimes be com- pletely removed in order to open the bottle.
• such a foil can also be used in combination with another closing device, in order to ameliorate the hygiene whilst handling the bottle, before it has been opened for consumption of its contents.
• Many of the known closing devices are difficult to use when the bottle is opened and its contents are to be used.
• a specially designed tool is in general needed in order to open a bottle equipped with a bottle cap not comprising a special opening device.
• Many of the known closing devices also require a certain force to be opened, whereby the user risks spilling the contents of the bottle when opened.
• closing devices have the problem that the bottle cannot be resealed using the closing device.
• the person that will consume the liquid is usually forced either to empty the container at once or to throw away beverage that is not wanted at once at the time when the container is opened. This is not desirable, since many people want to drink often and little rather than everything at once.
• the commonplace PET bottle with a screw cork solves the problem with resealability, but is associated with the problem of it being difficult for a small-mouthed person to drink from.
• it is difficult to maintain a good hygiene since this demands that the lips of the user are not brought so far down the opening of the bot- tie when drinking so that they come into contact with that part of the outside surface of the bottle which has been exposed to the environment when the screw cork was first attached.
• the hygiene problem is solved by using an external device, for example a straw or a glass. However, this demands that the user has access to such an external device at the time when he or she wishes to drink from the bottle, alternatively that such a device is provided jointly together with the bottle.
• the present closing device for a bottle solves all of the above described problems.
• the present invention relates to a closing device for a bottle containing liquid, where an opening exists to drink from, which opening is sealed by the use of the closing device, and is characterized in that said closing device consists of a lower part, arranged to be tight-fittingly at- tached to the opening of the bottle, and an upper part, removably attached to said lower part, where said lower and upper parts have cooperating fastening means that removably fasten said upper part to said lower part, where said upper part comprises a cavity for receiving a straw, which straw is tight-fittingly attached to said lower part, and which straw extends through said lower part, down into the bottle essentially to the bottom of the bottle, where said cavity is equipped with a seal, arranged against the opening of the received straw, so that exchange of liquid and gas between the interior of the bottle and the environment through said straw is prevented, and where said cooperating fastening means are arranged so that the closing device can be opened by the removal of said upper part and resealed by the return of said upper

• Fig. 1 shows a first preferred embodiment of the closing device 1 according to the present invention.
• a lower part 3 of the closing device 1 is engaged by threads with the opening of the bottle 2, by the use of a threaded engagement 15.
• the lower part 3 of the closing device 1 has internal threads corresponding to the external threads on the bottle 2, so that the lower part 3 is engaged by threads to the opening of the bottle 2.
• the bottle 2 can be of a standard type, for example a PET bottle, in which case the threads of the lower part 3 are adapted so that they correspond to the existing threads on such a standard bottle 2.
• the threaded engagement 15 is tight-fitting, implying that gas as well as liquid and contaminants, such as bacteria, viruses, foreign compounds, etc., are prevented from passing into or out of the bottle 2 through the threaded engagement 15.
• a straw 4 runs through the lower part 3 and further down through the opening of the bottle 2 and down into the bottle 2. In order to facilitate for the user to drink, so that the user can utilize all of the contents 2 of the bottle through 5 the straw 4, the straw 4 runs essentially all the way to the bottom of the bottle 2.
• the straw 4 is tight-fittingly fastened to the lower part 3 of the closing device 1 using a tight-fitting sealing device 5.
• That the straw 4 is tight- fittingly fastened to the lower part 3 means that liquid and w gas essentially are prevented from exchange between the bottle 2 and its environment between the straw 4 and the lower part 3, but also that contaminations from the environment of the bottle 2, for example bacteria, viruses, foreign compounds, etc., are prevented from passing from the environment
• this upper part 6 0 can be removed from the lower part 3, but can also be refas- tened to the lower part 3.
• the user can open and reseal the closing device 1 a large number of times.
• the upper part 6 is removably and reattachably fastened to the lower part 3 by the use of a fastening device 7.
• the fastening device 7 is a snap lock.
• the upper part 6 is equipped with internal flanges 9, which hook into corresponding exter- 0 nal flanges 8, arranged on the lower part 3, as the upper part 6 is fastened to the lower part 3. Then, when the upper part 6 is pulled away from the lower part 3, using a force applied by the user of the closing device 1, the engagement brought into order by the flanges 8, 9, will come loose, and the engagement between the lower part 3 and the upper part 6 will be discontinued.
• other types of fastening devices between the lower part 3 and the upper part 6 are also possible, and are apparent to the person skilled in the arts.
• the straw 4 runs through the lower part 3.
• the straw 4 is also received in the interior of the upper part 6.
• a sealing device 10 for example in the form of a silicone pad.
• That the straw 4 closes tight-fittingly against the inside of the upper part 6 means that liquid and gas essentially are hindered from exchange between the interior of the straw 4 and the interior of the upper part 6, but also that contaminants from the environment of the bottle 2, for example bacteria, viruses, foreign com- pounds, etc., are hindered from passing from the interior of the upper part 6 to the interior of the straw 4.
• the straw 4 is fastened to the upper part 6 by the use of an additional fastening device 11, for example and in the present preferred embodiment in the form of a snap lock, consisting of inner flanges 12 arranged in the interior of the upper part 6, which, when the upper part 6 is fastened to the lower part 3, engage removably and reattachably with outer flanges 13 arranged on the external surface of the straw 4.

• the other preferred embodiment is similar to the first preferred embodiment.
• the lower part 3 instead of the lower part 3 engaging by threads with the bottle 2 through the sealing device 15, as shown in Fig. 1, in Fig. 2 the lower part 3 is tight-fittingly fastened to the bottle 2 by the fact that the lower part 3 has a sealing device 16 in the form of a conical plug, arranged to be able to be driven down the opening of the bottle 2, and thus tight-fittingly fasten the lower part 3 to the bottle 2, since the outside of the sealing device 16 comes into friction based engagement with the interior walls of the opening of the bottle 2.
• the conical plug 16 is preferably manufactured in a material offering high friction against materials common in bottles, for example glass or various plastic materials.
• a high friction material is rubber.
• the sealing device 16 is formed as a conical plug, it can be adapted so that it fits with a broad spectrum of commonly available bottles. Therefore, the sealing device 1 according to this second preferred embodiment is especially suitable for use as a separate sealing device on various types of bottles, such as glass bottles and PET bottles. Thus, the sealing device 1 according to the second preferred embodiment can advantageously be used repeatedly, with different bottles.
• the sealing device 1 is opened, through the upper part 6 being pulled away from the lower part 3, the sealing device 10 in the upper part 6 will no longer be tight-fitting against the opening of the straw 4, which is necessary for the user to be able to drink the contents of the bottle 2 through the straw 4.
• the sealing device 1 When the sealing device 1 is resealed, by the upper part 6 being refas- tened to the lower part 3, the sealing device 10 in the upper part 6 will again tight-fittingly close against the opening of the straw 4, and thereby guarantee that the contents of the bottle 2 are separated from the environment of the bottle 2 in a hygienical manner during further storage of the contents of the bottle 2.
