Further, at the lowermost part of the straw, there is provided a floating device necessary for receiving the buoyancy of the liquid, and relates to a floating straw and a method of using the floating straw.

Background Art

[0002] Straws have become an item firmly established in our daily lives, and their convenience goes without saying. On the other hand, life scenes and lifestyles change with the times, and the usage patterns of straws are also diversifying with the times.

[0003] One of the reasons for this is the evolution of daily necessities. For example, beverages filled in plastic bottle containers can be cited. While we consumers are benefiting from this, the usage scenes of straws are diverse. Plastic bottle beverages are widely spread beyond private use and use in ordinary households, such as being provided to attendees at meetings and participants in seminars and symposiums. On the other hand, in quiet meeting places, there are scattered scenes where consideration is also required for the way of drinking beverages. For example, when drinking up tea, there are many cases where one is reluctant to make the sound of opening and closing the cap and then making a sound while drinking. In such cases, the straw is very convenient.

[0004] In recent years, due to the impact of the COVID-19 pandemic, the hygiene concepts and awareness of individuals have been heightened, and there are quite a few users who avoid directly putting their mouths on the mouth of the beverage container to ingest beverages and prefer to use straws. Under such circumstances, in the development of straws, ideas and products that pursue greater convenience for users have been seen since ancient times.

[0005] For example, according to Patent Document 1, there is provided a straw with a floating ring that is designed to make it easier to drink beverages. A technique of attaching a disc-shaped floating body to the tip of the straw and using it is disclosed. This is because the floating body serves as a floating ring, and when the cap of the PET bottle is opened, the straw always floats gently upward from the beverage opening of the PET bottle.

[0006] The invention according to Patent Document 1 solves the problems of the prior art. Specifically, it is for solving the problems of "the problem when inserting a short straw (difficult and troublesome to take out)", "the problem when inserting a long straw (folding it and inserting a finger and having to pull it out)", and "the hygiene aspect when taking out the straw (if the hand is dirty, it is unhygienic)".

[0007] Patent Document 2 constitutes a technology that further develops the idea of Patent Document 1. That is, according to Patent Document 2, it provides a straw dedicated to PET bottles that can easily form a lid even when a straw is inserted and can be easily opened when one wants to drink and the straw can be lifted. As the upper-level idea, it is consistent with the purpose and track of the invention according to Patent Document 1. However, in Patent Document 2, as a means for solving the technical problem, the buoyancy means is different from that in Patent Document 1. That is, it provides a straw characterized by providing a buoyancy means in the vicinity of the end of the straw using a foamed material of synthetic resin.

[0008] However, both Patent Document 1 and Patent Document 2 have a common fatal flaw. That is, since the floating ring or the floating of the foaming material depends on the position of the liquid surface, if the liquid is not sucked immediately when the lid of the container is opened, the entire straw will gradually float, and the straw will be exposed from the mouth part. Therefore, it is essential to open and close the lid every time you drink. Even if the liquid level drops, due to the open mouth part, the exposure and directionality of the straw are not stable, so you will touch the upper part of the straw with your finger, which is unhygienic. For these reasons, Patent Documents 1 and 2 do not provide a radical solution to the conventional technical problems and are still insufficient.

[0009] Patent Document 3 discloses an invention related to a plastic bottle with a straw for storing drinking water and sucking and drinking it with a straw as appropriate. Specifically, it discloses an invention based on the idea that it can be carried integrally with the plastic bottle, and can cope with the hygienic storage and reuse of the straw, and the lower end suction port of the straw is always placed at a predetermined position at the bottom of the plastic bottle so as not to be in an unstable state.

[0010] According to the invention of Patent Document 3, by providing a bellows in the central part of the straw, the problem of the rise and fall of the straw due to the change in the liquid level found in Patent Documents 1 and 2 is solved. However, although the bottom part is fixed, due to the opening of the mouth part, the problem that the upper part of the straw is unstable has not been solved yet. Furthermore, by providing a fixed structure at the bottom, liquid residue occurs due to the height of the receiving part, resulting in a suction loss in the container. In this regard, it is inferior to Patent Documents 1 and 2 and has no progress as a technology.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described in detail including the effects achieved thereby.

[0018] As described above, the present invention provides a floating straw with a stopper that is hygienic and has excellent operability for beverage containers, and a method of using the same. In particular, when drinking a liquid for beverages in a container, the main object is to provide a functional straw that can be drunk to the last drop without causing discomfort to the surroundings, and a method of using the same.

[0019] According to claim 1 of the present invention, there is provided a floating straw (reference numeral 1 in FIG. 1) that rises by the buoyancy of a liquid filled in a beverage container (reference numeral 5 in FIG. 1). At the uppermost part of the straw, there is a bellows part (reference numeral 2 in FIG. 1) having a length equal to or greater than the neck length of the container (reference numeral 7 in FIG. 1). The bellows part is provided with a stopper (reference numeral 3 in FIG. 1) having a diameter size equal to or greater than the inner diameter of the mouth at the root part (reference numeral 6 in FIG. 1) of the beverage container. Further, at the lowermost part of the straw, there is provided a floating member (reference numeral 4 in FIG. 1) necessary for receiving the buoyancy of the liquid.

[0020] Here, the stopper 3 is appropriately changed in size according to the dimensions of the container 5, and is a circular flat plate. Its diameter is designed to be larger than the inner diameter of the mouth of the container. This is because it is an essential condition for ensuring the function of fixing the upward movement of the straw at the root part 6 of the collar. The position of the stopper with respect to the longitudinal direction of the container should be such that the tip of the straw protrudes within a position range where it is easy to suck at the mouth with respect to the neck length 7 of the container during liquid suction. The adjustment is appropriately made in the bellows part 1. To facilitate the adjustment, a resin material capable of imparting stretchability and elasticity is applied to the stopper material. The floating member 4 provided at the lowermost part of the straw may have any size and shape as long as it can obtain a buoyancy force that raises the straw upward in the longitudinal direction within the container against the straw load. Also, the material of the floating member is not particularly limited as long as its safety is acceptable for beverages and is arbitrary.

[0021] That is, according to claim 2 of the present invention, when the amount of liquid filled in the beverage container remains at least the neck length of the beverage container, the straw rises due to the buoyancy of the liquid, and when the stopper is fixed at the position of the root of the neck of the beverage container, the distance between the lowermost part of the straw and the bottom surface of the beverage container is the same dimension as the neck length, and the floating straw according to claim 1 is provided. Further, according to claim 1 of the present invention, a floating straw is provided, wherein the stopper provided at the bellows part at the uppermost part of the straw is movable. Furthermore, according to claim 1 of the present invention, a floating straw is provided, wherein the stopper provided at the bellows part at the uppermost part of the straw is made of a resin having elasticity and elasticity.

[0022] By using the straw of the present invention having the above functions, the beverage can be sucked cleanly and hygienically, and since the straw can be in close contact with the bottom surface of the container, the liquid in the container can be drunk up.

[0023] That is, According to claim 3 of the present invention, the floating straw described in claim 1 provided in it enables the position adjustment of the movable stopper to suck and drink up all of the liquid filled in the beverage container from the mouth of the beverage container at a certain distance it A method of using a floating straw with a stopper is provided.

[0024] Hereinafter, the usage mode of the cap in the present invention will be described. As illustrated on the right side of FIG. 1, reference numeral 8 is a typical rotary screw-type cap used in the present invention. By tightening the cap, the bellows part above the straw contracts, and the stopper moves to the lower part of the container. The distance of the stopper movement is due to the balance between the resistance of the bellows part and the buoyancy.

[0025] On the left side of Figure 1, the cap is opened to expose the top of the container opening. Due to buoyancy, the straw rises, but due to the fixing function of the stopper, the bellows part of the straw protruding from the top of the opening always remains constant. When the liquid level in the container drops below the dimension corresponding to the neck length, the bellows part protruding from the top of the opening gradually descends, but until the floating device reaches the bottom surface of the container, all the beverage in the container can be drunk up.

[0026] In addition, there are no special restrictions on the variations of the cap. In addition to the rotary screw type adopted in Figure 1, known types such as a one-touch type in which a part of the cap is fixed near the top of the opening can be adopted. Also, when considering convenience outdoors, in the case of a separate type cap, it is optional to take measures to prevent the loss of the cap by providing a hole for threading a string on the ceiling of the cap. It is also convenient to provide a fixed joint inside the cap and adopt a specification of fixing it to the inner corner of the mouth of the container.
