Description

本考案は飲料物が封入された紙パックなどの容器から飲用するための液体封入容器用ストローに関する。   The present invention relates to a straw for a liquid-sealed container for drinking from a container such as a paper pack in which a beverage is enclosed.

従来、飲料入り紙パックの外側と一体的に付着されているストローを用いて、紙パック内部の飲料物を吸引すると、紙パック内部は減圧し、紙パックが変形して飲料物の吸引が次第に難しくなるため、ストローからしばらく口を離して再び吸引することを繰り返さなければならないという使用上の不便があった。また、この時、紙パック内部に急激に空気が入り込むことにより、不快音が発生し易かった。このため近年に於いては、ストローの側部で長手方向に溝や突状部を設け、飲料物の吸引がスムーズに行えるように工夫したものが多種類提案されている。又、この長手方向に溝や突状部を設ける場合は、特に突状部をストローの上部まで付けると、吸い口として突状部が気になって不快感となるため、一般には突状部がストローの中間部のみに付けられている。また前記溝よりも前記突状部を作った方が空気の出入りが良好になる。   Conventionally, when a beverage inside a paper pack is sucked using a straw that is integrally attached to the outside of the beverage-containing paper pack, the inside of the paper pack is depressurized, and the paper pack is deformed to gradually suck the beverage. Because it becomes difficult, there is an inconvenience in use in which it is necessary to keep the mouth away from the straw for a while and to repeat the suction again. At this time, unpleasant noise was likely to occur due to the sudden entry of air into the paper pack. For this reason, in recent years, many types have been proposed in which grooves and protrusions are provided in the longitudinal direction on the side of the straw so that the beverage can be sucked smoothly. Also, when providing a groove or protrusion in the longitudinal direction, especially when the protrusion is attached to the upper part of the straw, the protrusion is anxious as a mouthpiece. Is attached only to the middle part of the straw. In addition, the air entering / exiting is better when the protruding portion is formed than the groove.

特にストローの側部で長手方向に突状部を設け、吸引の際に飲料容器内が減圧されることを防止し、飲み易く、且つ不快音を発生させないために提案されたものとして、特開2001−269258があり、このストローの構造は、形の異なる2本以上の管が伸縮自在に組合され、且つ、最も外側に位置する最外管の外周壁に、その長手方向に沿って1本以上の凸条が形成された多段式ストローであった。   In particular, it has been proposed that a protruding portion is provided in the longitudinal direction on the side of the straw to prevent the inside of the beverage container from being depressurized during suction, to be easy to drink, and not to cause unpleasant noise. 2001-269258, the structure of this straw is such that two or more tubes having different shapes are stretchably combined, and one outer circumferential wall of the outermost tube is disposed along the longitudinal direction of the outermost tube. It was a multistage straw in which the above ridges were formed.

しかしながら、特開2001−269258の凸条(突状部)は、文中に記載されているように最外管の外周壁の基準面から0.2〜1.0mmであることが好ましく、基準面から1.0mmを超えると、凸条の成形が困難になると明記されている。このため、紙パック内部の飲料物を吸引する際、紙パックの上壁に設けられた吸引穴をストローによって破り、紙パック内部に多段式のストローを差し込む。すると、吸引穴の周縁はストローの凸条(突状部)によって押し広げられ、吸引穴の周縁とストローの周面との間に若干の隙間が出来るが、飲料物を吸引し続けると、凸条の断面形状が略半円状であるため、吸引穴の周縁とストローの周面がなじんでしまい、若干の隙間がなくなって密着した状態になり易く、飲料物を最後の一滴までスムーズに吸引することが難しいものであった。
特開2001−269258号公報
However, the protrusions (projections) of JP-A-2001-269258 are preferably 0.2 to 1.0 mm from the reference surface of the outer peripheral wall of the outermost tube as described in the text, If the thickness exceeds 1.0 mm, it is specified that it becomes difficult to form the ridges. For this reason, when the beverage inside the paper pack is sucked, the suction hole provided in the upper wall of the paper pack is broken by a straw, and a multistage straw is inserted into the paper pack. Then, the peripheral edge of the suction hole is expanded by the straw ridges (protrusions), and a slight gap is formed between the peripheral edge of the suction hole and the peripheral surface of the straw. Since the cross-sectional shape of the strip is almost semicircular, the peripheral edge of the suction hole and the peripheral surface of the straw become familiar, and it is easy to be in close contact with each other, so that the beverage can be sucked smoothly up to the last drop. It was difficult to do.

本考案は吸引の際に常に空気抜き用の隙間が確保されて飲料容器内の減圧を防ぎ、飲み易く、且つ不快音を発生させない液体封入容器用ストローを提供することを目的とする。   An object of the present invention is to provide a straw for a liquid-filled container in which a clearance for removing air is always secured during suction to prevent decompression in the beverage container, and it is easy to drink and does not generate unpleasant noise.

本考案の他の目的は、空気抜き用の隙間をより広く確保することが可能となる液体封入容器用ストローを提供するにある。   Another object of the present invention is to provide a straw for a liquid enclosure that can secure a wider gap for air venting.

本考案は上記現状に鑑み成されたものであり、つまり、ストロー本体の外周壁で且つその長手方向に沿って1本以上の突状部を形成させ、且つ、突状部に、ストロー本体の中心軸に対して傾斜角を設けた構造とする。また前記ストロー本体として、径の異なる2本以上の管を伸縮自在に組合せた多段式ストローの最外管を用いると良い。また、前記突状部をストロー本体の長手方向に対して2本以上形成しても良く、その突状部の断面形状を三角山とするのが好ましい。   The present invention has been made in view of the above situation, that is, one or more projecting portions are formed along the longitudinal direction of the outer peripheral wall of the straw body, and the projecting portion of the straw body is formed on the projecting portion. The tilt angle is provided with respect to the central axis. Further, as the straw body, it is preferable to use an outermost pipe of a multistage straw in which two or more pipes having different diameters are combined in an extendable manner. Two or more protrusions may be formed in the longitudinal direction of the straw body, and the cross-sectional shape of the protrusions is preferably a triangular mountain.

請求項1のようにストロー本体(1)の外周壁で且つその長手方向に沿って1本以上の突状部(2)を形成させ、且つ、突状部(2)に、ストロー本体(1)の中心軸に対して傾斜角(θ)を設けることにより、吸引穴の周縁が突状部(2)の先端から後端近くまで差込むことによって徐々に広げられるため、突状部(2)1本分の幅以上の広い隙間が確保されるものとなる。従って、吸引の際に常に空気抜き用の隙間が確保されて飲料容器内の減圧を防ぎ、飲み易く、且つ不快音が発生されないものとなる。   As in claim 1, one or more protrusions (2) are formed on the outer peripheral wall of the straw body (1) along the longitudinal direction thereof, and the straw body (1) is formed on the protrusion (2). ) With respect to the central axis, the peripheral edge of the suction hole is gradually widened by being inserted from the front end of the projecting portion (2) to the vicinity of the rear end, so that the projecting portion (2 ) A wide gap more than one width is secured. Therefore, a gap for air venting is always ensured during suction to prevent decompression in the beverage container, and it is easy to drink and no unpleasant noise is generated.

請求項2のようにストロー本体(1)として、径の異なる2本以上の管を伸縮自在に組合せた最外管が用いられると、多段式ストローに対しても請求項1と同様の効果が得られる。   When the outermost tube in which two or more tubes having different diameters are combined in a stretchable manner as the straw body (1) as in claim 2, the same effect as in claim 1 can be obtained for a multistage straw. can get.

請求項3に示すように突状部(2)を、ストロー本体(1)の長手方向に対して2本以上形成させることにより、吸引穴の周縁が突状部(2)の先端から後端近くまで差込むことが2回行われる結果となるため、吸引穴の周縁がしっかりと広げられた隙間となり、その隙間は、極めてなじみにくい空気抜き用の隙間が確実に保持されるものとなる。   As shown in claim 3, by forming two or more projecting portions (2) in the longitudinal direction of the straw body (1), the peripheral edge of the suction hole extends from the front end of the projecting portion (2) to the rear end. As a result of being inserted twice, it is a gap in which the periphery of the suction hole is firmly widened, and the gap reliably holds a gap for air venting that is extremely unfamiliar.

請求項4に示すように突状部(2)の断面形状を三角山とすることにより、従来の略半円状の如く吸引穴の周縁とストローの周面がなじむ恐れがなくなり、飲料物を最後の一滴までスムーズに吸引することが可能となる。   By making the cross-sectional shape of the projecting portion (2) a triangular mountain as shown in claim 4, there is no fear that the peripheral edge of the suction hole and the peripheral surface of the straw will become familiar as in the conventional semi-circular shape. It is possible to suck up to the last drop smoothly.

図1、図2は本考案の実施形態を示す図であり、これに基づき説明する。(1)は内管(3)を出入自在に内設した2段式で合成樹脂製のストロー本体である。尚、前記ストロー本体(1)は2段式のものに限定されるものではなく、1段式のもの或いは3段式以上のものでも良い。(2)はストロー本体(1)の外周壁で且つその長手方向に沿って形成させた1本の突状部であり、該突状部(2)は外周壁の上下或いは左右で合計2本形成されている。また前記突状部(2)の断面形状としては図4に示すような三角山とし、その高さを1mm以上にするのが好ましいが、1mm以下でも良い。又、前記突状部(2)には、ストロー本体(1)の中心軸に対して傾斜角(θ)が設けられている。その傾斜角(θ)としては、2〜10度前後の範囲が好ましいが、この範囲に限定されるものではない。また前記突状部(2)の本数も円周方向で2本に限定されるものではない。尚、前記突状部(2)の断面形状が三角山に形成させる方法及びその高さを1mm以上とする方法は、本考案者が特願2006−303598で提案した「ストローの側部に形成する突状部の加工方法及びその加工用装置」を用いると良い。(4)は内管(3)がストロー本体(1)から抜け出ないようにするための絞り部である(図2参照)。   FIG. 1 and FIG. 2 are diagrams showing an embodiment of the present invention, which will be described based on this. (1) is a two-stage straw body made of synthetic resin with an inner tube (3) removably installed. The straw body (1) is not limited to a two-stage type, and may be a one-stage type or a three-stage type or more. (2) is an outer peripheral wall of the straw body (1) and one projecting portion formed along the longitudinal direction thereof, and the projecting portion (2) is a total of two on the upper and lower or left and right sides of the outer peripheral wall. Is formed. Further, the cross-sectional shape of the projecting portion (2) is a triangular mountain as shown in FIG. 4, and the height is preferably 1 mm or more, but may be 1 mm or less. The protrusion (2) is provided with an inclination angle (θ) with respect to the central axis of the straw body (1). The inclination angle (θ) is preferably in the range of about 2 to 10 degrees, but is not limited to this range. Further, the number of the protruding portions (2) is not limited to two in the circumferential direction. The method of forming the cross-sectional shape of the projecting portion (2) in a triangular mountain and the method of setting its height to 1 mm or more are described in Japanese Patent Application No. 2006-303598, which is “formed on the side portion of the straw”. It is preferable to use a method for processing a protruding portion and a processing apparatus for the same. (4) is a throttle part for preventing the inner tube (3) from coming out of the straw body (1) (see FIG. 2).

図3は本考案の別実施形態を示す図であり、これは前記実施形態と比べ、突状部(2)が長手方向で2本設けられたものであり、他は同じである。尚、前記突状部(2)の本数は2本以上でも良い。   FIG. 3 is a view showing another embodiment of the present invention, which is provided with two protrusions (2) in the longitudinal direction, and the other is the same as the embodiment. The number of the projecting portions (2) may be two or more.

次に本考案の作用について説明する。先ず始め紙パック内部の飲料物を吸引する際には、従来と同様に、紙パックの上壁に設けられた吸引穴をストローの先端によって破り、紙パック内部に2段式のストローを差し込む。すると、ストロー本体(1)の突状部(2)によって、吸引穴の周縁が押し広げられ、吸引穴の周縁とストローの周面との間に、空気抜き用の隙間が確保される。この時、突状部(2)は、ストロー本体(1)の中心軸に対して傾斜角(θ)が設けられているので、吸引穴の周縁が徐々に広げられて、突状部(2)1本以上の幅の隙間が確保されるものとなる。従って、空気抜き用の隙間が確実に保持された状態となり、飲料容器内の減圧防止が行え、減圧による様々な問題が解決できるものとなった。   Next, the operation of the present invention will be described. First, when the beverage inside the paper pack is sucked, the suction hole provided in the upper wall of the paper pack is broken by the tip of the straw, and a two-stage straw is inserted into the paper pack, as in the prior art. Then, the peripheral edge of the suction hole is pushed and widened by the protruding portion (2) of the straw body (1), and a gap for air venting is secured between the peripheral edge of the suction hole and the peripheral surface of the straw. At this time, since the protrusion (2) is provided with an inclination angle (θ) with respect to the central axis of the straw body (1), the peripheral edge of the suction hole is gradually widened, and the protrusion (2 ) One or more gaps are secured. Accordingly, the air vent gap is securely held, the pressure reduction in the beverage container can be prevented, and various problems due to the pressure reduction can be solved.
