Abstract

When drinking a beverage using a straw, the texture of the beverage can be switched.
A straw is composed of a first cylindrical portion and a second cylindrical portion having a smaller diameter than the first cylindrical portion, and a bubble generating portion consisting of a large number of holes is formed around the second cylindrical portion. When the expansion / contraction part 8 of the first cylindrical part 5 is contracted and a beverage is drunk with a mouth attached only to the upper end part of the second cylindrical part 6, foam is generated in the beverage sucked into the second cylindrical part 6. Since air sucked from a large number of holes in the portion 10 is mixed, fine bubbles can be included in the beverage. On the other hand, when the expansion / contraction part 8 of the first cylindrical part 5 is extended and the upper end part of the first cylindrical part 5 is attached to drink the beverage, the beverage does not contain bubbles.

Description

  The present invention relates to a drinking straw capable of producing a new texture.

  Conventionally, straws are used to drink beverages. Such a drinking straw consists of an internal straw and an external straw with different diameters. The internal straw is stored in the external straw to shorten the length, and when drinking beverages, the internal straw is removed from the external straw. 2. Description of the Related Art A two-stage telescopic straw for drinking is known in which the overall length of the straw is pulled out and the lengthened straw is inserted into a beverage container.

  On the other hand, there has also been proposed a straw that creates a new texture by forming air intake holes and appropriately mixing air that is taken from the air intake holes into the beverage to contain bubbles in the beverage being consumed. (See Patent Document 1).

JP 2011-101750 A

  However, although the straw described in Patent Document 1 can create a new texture, the beverage always contains bubbles. For this reason, when it is desired to drink a beverage without including bubbles, it is necessary to prepare a separate straw.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to switch the texture of a beverage when drinking the beverage using a straw.

  The drinking straw according to the present invention includes a first cylindrical portion and a second cylindrical portion having a diameter smaller than that of the first cylindrical portion and accommodated coaxially in the first cylindrical portion, One end portion of the cylindrical portion and one end portion of the second cylindrical portion corresponding to the one end portion are in close contact with each other, and a bubble generating portion including at least one hole is formed around the second cylindrical portion. It is characterized by.

  “Close contact” means that one end of the first cylindrical portion and the one end of the second cylindrical portion are crimped, bonded, joined, or engaged, etc. Means a state where the liquid is closed to the extent that the liquid does not pass under normal pressure.

  In addition, “one end portion” means an end portion on the beverage side that cannot be added to the mouth when the straw is used.

  Moreover, in the drinking straw by this invention, a foam production | generation part may consist of a some hole.

  Moreover, in the drinking straw according to the present invention, a plurality of holes may be formed side by side in the longitudinal direction of the second cylindrical portion around the second cylindrical portion.

  In the drinking straw according to the present invention, the first cylindrical portion is formed with an extendable portion that changes its length so that the other end opposite to the one end of the second cylindrical portion is exposed. May be.

  Moreover, in the drinking straw by this invention, you may make the diameter of the other end part on the opposite side to the one end part of a 2nd cylindrical part larger than the diameter of parts other than an other end part.

  In the drinking straw according to the present invention, the diameters of the first cylindrical portion and the second cylindrical portion may be reduced in a tapered shape in the vicinity of one end portion.

  Moreover, the drinking straw according to the present invention may further include a third cylindrical portion that is retractably accommodated in the second cylindrical portion.

  According to the drinking straw of the present invention, when drinking a beverage with a mouth on both the first and second cylindrical portions or only on the first cylindrical portion, the beverage is the first cylindrical portion and the second cylindrical portion. The two cylindrical portions are sucked into the beverage straw from one end where they are in close contact, pass through the second cylindrical portion, and are sucked out from the other end. For this reason, a drink can be drunk like a general straw without a hole. On the other hand, when drinking a beverage with a mouth attached only to the second cylindrical portion, the beverage is sucked into the drinking straw from one end where the first cylindrical portion and the second cylindrical portion are in close contact with each other. Since the air sucked into the gap between the first cylindrical portion and the second cylindrical portion is sucked into the second cylindrical portion from the bubble generating portion, Air is mixed into the beverage and sucked out from the other end. Thereby, fine air bubbles can be included in the beverage by the air taken in from the at least one hole in the beverage, and as a result, a smooth texture can be given to drinking. Therefore, the drinking straw of the present invention can be switched between drinking including bubbles and drinking not including bubbles, so that the user can drink the beverage with a desired texture.

  Moreover, since a foam production | generation part consists of a some hole, it can be drunk including many bubbles in a drink.

  In addition, by forming a plurality of holes side by side in the longitudinal direction of the second cylindrical portion around the second cylindrical portion, the beverage can be drunk with less change in texture due to the remaining amount of beverage. Can do.

  In addition, by forming the expansion / contraction part in the first cylindrical part, if the expansion / contraction part is contracted, only the second cylindrical part can be exposed outside the first cylindrical part. It becomes easy to put only the mouth. Moreover, if the expansion / contraction part is extended, a mouth can be easily attached to both the first and second cylindrical parts or only to the first cylindrical part. Therefore, it is possible to easily switch between drinking including bubbles and drinking without bubbles.

  Also, by making the diameter of the other end opposite to the one end of the second cylindrical part larger than the diameter of the part other than the other end, the mouth is attached only to the second cylindrical part and the beverage is served. When drinking, since a larger negative pressure can be generated in many holes, air can be taken into the second cylindrical portion more vigorously. Therefore, the smoothness of the beverage to be drunk can be further improved.

  In addition, by reducing the diameters of the first cylindrical portion and the second cylindrical portion in the vicinity of one end portion in a tapered shape, it becomes easy to bring the first end portions of the first and second cylindrical portions into close contact with each other.

  In addition, the beverage straw according to the present invention can be configured as a telescopic two-stage straw by further including a third cylindrical portion that is retractably accommodated in the second cylindrical portion. When the two-stage straw is used, the third cylindrical portion presses the end portions of the first and second cylindrical portions from the inside of the second cylindrical portion, so one end of the first and second cylindrical portions. The parts can be brought into close contact with each other.

The external view which shows the structure of the drinking straw by embodiment of this invention External view showing configuration of external straw External view showing another configuration of the second cylindrical portion External view showing configuration of internal straw The figure which shows the state which contracted the expansion-contraction part The elements on larger scale which show the structure of the drinking straw by the 2nd Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing a configuration of a drinking straw according to an embodiment of the present invention. As shown in FIG. 1, a drinking straw (hereinafter, simply referred to as a straw) 1 according to the present embodiment is configured as a two-stage straw in which an internal straw 3 is retractably accommodated in an external straw 2. ing. Fig.1 (a) shows the state which the straw 1 of this embodiment contracted, FIG.1 (b) shows the expanded state, respectively. Moreover, in FIG.1 (b), the expansion-contraction part mentioned later is also contracted. The internal straw 3 corresponds to the third cylindrical portion.

  FIG. 2 is a diagram showing the configuration of the external straw 2. As shown in FIG. 2, the external straw 2 includes a first cylindrical portion 5 and a second cylindrical portion 6. The second cylindrical portion 6 has substantially the same length as the first cylindrical portion 5 and a smaller diameter than the first cylindrical portion 5, and the first cylindrical portion 5 is in the first cylindrical portion 5. And is stored coaxially. Since the second cylindrical portion 6 has a smaller diameter than the first cylindrical portion 5, a gap 7 is formed between the first cylindrical portion 5 and the second cylindrical portion 6.

  The first cylindrical portion 5 and the second cylindrical portion 6 are tapered in the vicinity of the end portion (hereinafter referred to as the lower end portion) on the side where the beverage is sucked during use, and the lower end portion The first cylindrical portion 5 and the second cylindrical portion 6 are in close contact so that the gap 7 is closed. Here, the lower end portions of the first cylindrical portion 5 and the second cylindrical portion 6 may be joined, pressure-bonded, and bonded by a known method such as ultrasonic welding to close the gap 7, The gap 7 may be closed by engaging the first cylindrical portion 5 with the second cylindrical portion 6. In the following description, the end that is the side added to the mouth opposite to the lower end is referred to as the upper end.

  The first cylindrical portion 5 is formed with a bellows-like stretchable portion 8, and the stretchable portion 8 makes the first cylindrical portion 5 stretchable with respect to the second cylindrical portion 6. In addition, in the state which extended the expansion-contraction part 8, the position of the upper end part of the 1st cylindrical part 5 and the 2nd cylindrical part 6 is aligned, and if the expansion-contraction part 8 is contracted, the 2nd cylindrical part 6 of The upper end is exposed to the outside.

  The second cylindrical portion 6 is formed with a bubble generating portion 10 composed of a large number of holes. The foam generating unit 10 is composed of a large number of holes arranged along the circumferential direction and the longitudinal direction of the second cylindrical unit 6. In FIG. 2, the bubble generation unit 10 is formed in a range from a portion corresponding to the expansion / contraction portion 8 of the first cylindrical portion 5 to the lower end portion in the second cylindrical portion 6, but is not limited thereto. However, it may be formed in a range from the portion corresponding to the stretchable portion 8 to the upper end portion.

  In addition, the range for forming the bubble generating unit 10 is not limited to that shown in FIG. 2, and is formed in a relatively narrow range in the longitudinal direction of the second cylindrical unit 6 as shown in FIG. 3. Also good. Moreover, although the hole of the foam production | generation part 10 may be distributed equally as shown in FIG. 2 and FIG. 3, it is not specifically limited. By forming the hole of the bubble production | generation part 10 in the upper end part side of the 2nd cylindrical part 6, while the mellowness of texture can be increased, there exists a tendency for a bubble to become large too much. Moreover, as above-mentioned, if the hole of the foam production | generation part 10 is not formed in the lower end part side of the 2nd cylindrical part 6, if the residual amount of a drink reduces, the production | generation of foam may become difficult. Therefore, the holes of the foam generation unit 10 may be distributed so that the number of the lower end side of the second cylindrical unit 6 is larger than the number of the upper end side according to the required degree of smoothness of the beverage. .

  Also, the smaller the pore size, the smaller the bubbles are formed and the better the texture. By reducing the hole diameter, the sound generated when bubbles are generated can be reduced. Moreover, although a hole is not limited to two or more, by making it into a several hole, many bubbles are formed and food texture can be made more favorable. Moreover, even if the remaining amount of the beverage is changed, a good foam texture can always be maintained by providing a large number of straws arranged in the length direction. The number, size, pitch, and the like of the holes vary depending on the type of beverage, but for example, a large number (several tens to several hundreds) of fine holes that can be at the tip of the needle is desirable. In addition, a large-diameter portion 11 having a larger diameter than the other portions of the second cylindrical portion 6 is formed at the upper end portion of the second cylindrical portion 6. A stopper 12 made of an annular groove is formed near the lower end.

  FIG. 4 is an external view showing the configuration of the internal straw 3. As shown in FIG. 4, the internal straw 3 is configured to be slightly longer than the external straw 2. Moreover, although the diameter is comprised smaller than the 2nd cylindrical part 6, the diameter of an upper end part is expanded rather than the other part. In addition, the diameter of the upper end part of the internal straw 3 has substantially the same size as the parts other than the lower end part and the upper end part of the second cylindrical part 6. By increasing the diameter of the upper end portion of the internal straw 3 in this way, when the straw 1 of the present embodiment is extended, the upper end portion of the internal straw 3 is reduced in diameter to the taper shape of the second cylindrical portion 6. The inner straw 3 is prevented from coming out of the outer straw 2 by engaging with the lower end portion. Further, since the stopper 12 is formed at the lower end portion of the second cylindrical portion 6 of the external straw 2, the upper end portion of the drawn out internal straw 3 is locked to the stopper 12, and the internal straw 3 is connected to the external straw. 2 is not drawn into.

  Since the upper end portion of the drawn internal straw 3 presses the lower end portions of the first cylindrical portion 5 and the second cylindrical portion 6 from the inside, the sealing performance of the gap 7 can be further enhanced.

  Moreover, the lower end part of the internal straw 3 is cut | disconnected diagonally, Thereby, it becomes easy to stab the straw 1 of this embodiment to the container of a drink.

  Next, a method for using the straw 1 of the present embodiment will be described. First, the internal straw 3 is pulled out from the external straw 2, the straw 1 is extended, stabbed into a beverage container, and the beverage is drunk. At this time, if the expansion / contraction part 8 of the first cylindrical part 5 is in the extended state, the upper ends of the first cylindrical part 5 and the second cylindrical part 6 are aligned. Only 5 will be used to drink beverages. In this case, when the user performs an operation of sucking a beverage, the beverage that has been sucked into the internal straw 3 and passed therethrough is from the lower end where the first cylindrical portion 5 and the second cylindrical portion 6 of the external straw 2 are in close contact. It is sucked into the external straw 2, passes through the inside of the second cylindrical portion 6, and is sucked out from the upper end portion. For this reason, a drink can be drunk like a general straw without a hole.

  On the other hand, as shown in FIG. 5, when the expansion / contraction part 8 of the first cylindrical part 5 is contracted, the upper end part of the second cylindrical part 6 is exposed to the outside. A drink is given with a mouth only. In this case, when the user performs an operation of sucking a beverage, the beverage that has been sucked into the internal straw 3 and passed therethrough is from the lower end where the first cylindrical portion 5 and the second cylindrical portion 6 of the external straw 2 are in close contact. It is sucked into the outer straw 2 and passes through the inside of the second cylindrical portion 6. On the other hand, since the upper end portion of the first cylindrical portion 5 is not held in the mouth, air is sucked into the gap 7 from the upper end portion of the first cylindrical portion 5 by the operation of sucking the beverage of the user, It is sucked into the inside of the second cylindrical part 6 from a large number of holes of the foam generating part 10. Thereby, air is mixed with a drink and it sucks out from an upper end part. Therefore, fine air bubbles can be included in the beverage by the air taken in from a large number of holes, and as a result, a smooth texture can be given for drinking.

  Thus, according to the straw 1 of this embodiment, it is possible to switch between drinking including bubbles and drinking not including bubbles by expanding and contracting the expansion and contraction portion 8, so that the user has a desired texture. Can drink beverages.

  Moreover, in the straw 1 of this embodiment, since the large diameter part 11 is formed in the upper end part of the 2nd cylindrical part 6, when attaching a mouth only to the 2nd cylindrical part 6 and drinking a drink A larger negative pressure can be generated in a large number of holes. Therefore, air can be taken in into the 2nd cylindrical part 6 more vigorously, As a result, the smoothness of the drink to drink can be improved more.

  Moreover, in the said embodiment, although the expansion-contraction part 8 is made into the bellows shape, it is not limited to this, For example, it is set as the two-stage type which combined two cylindrical parts so that expansion and contraction was possible. Any configuration can be employed as long as the cylindrical portion 5 can be expanded and contracted.

  Moreover, in the said embodiment, although the lower end of the 1st cylindrical part 5 and the 2nd cylindrical part 6 is formed in the taper shape, it is not limited to this, The 1st cylindrical part 5 and the 1st Any shape can be adopted as long as the lower ends of the two cylindrical portions 6 are joined.

  Moreover, in the said embodiment, although the large diameter part 11 is formed in the upper end part of the 2nd cylindrical part 6, even if it does not form the large diameter part 11, a mouth is attached only to the 2nd cylindrical part 6. When drinking a beverage, negative pressure can be generated in a large number of holes. For this reason, the large diameter portion 11 may not be formed.

  Moreover, in the said embodiment, although the straw 1 is made into the two-stage type straw which combined the external straw 2 and the internal straw 3 so that expansion-contraction is possible, you may comprise the straw 1 only from the external straw 2. FIG. In this case, the stopper 12 of the second cylindrical portion 6 can be omitted. Further, it is not necessary to form the lower ends of the first cylindrical portion 5 and the second cylindrical portion 6 in a tapered shape.

  Moreover, in the said embodiment, although the expansion-contraction part 8 is formed in the 1st cylindrical part 5, you may make it not form the expansion-contraction part 8. FIG. In this case, since the positions of the upper ends of the first cylindrical portion 5 and the second cylindrical portion 6 coincide, it is difficult to switch between drinking including bubbles and drinking not including bubbles. For this reason, the first cylindrical portion 5 may be formed to be slightly shorter than the second cylindrical portion 6 so that the upper end portion of the second cylindrical portion 6 is always exposed to the outside. Thus, in the case where the upper end of the second cylindrical portion 6 is always exposed to the outside, when drinking without including bubbles, the straw 1 is added to the upper end of the first cylindrical portion 5 and the bubbles are added. In the case of drinking including, only the upper end portion of the second cylindrical portion 6 may be added.

  Moreover, in the said embodiment, the recessed part as shown in FIG. 6 is formed in the vicinity of the lower end part of the 1st cylindrical part 5 and the 2nd cylindrical part 6, respectively, and the clearance gap 7 is formed by fitting each recessed part mutually. Sealability can be improved. And since the upper end part of the internal straw 3 engages with the lower end part of the 1st cylindrical part 5 and the 2nd cylindrical part 6 exceeding each recessed part, the sealing performance of the clearance gap 7 can also be improved further.

  Moreover, in the said embodiment, although it does not specifically limit about a drink, It is desirable that it is a liquid which has viscosity, such as dairy products, a cafe au lait, and soup.
