Definitions

  • the present invention relates to a straw which is removably inserted into a press-deformable container, such as a paper carton, containing a liquid food, e.g., beverages, noodle sauces or dips for grilled beef, and used to pour the liquid food. More particularly, it relates to a straw which easily pours the liquid food to the last drop, does not drip, is hygienic because the outer periphery of the opening thereof is hardly contaminated, and enables re-closing of the container.
  • a press-deformable container such as a paper carton
  • a liquid food e.g., beverages, noodle sauces or dips for grilled beef
  • a straw is removably inserted into a paper carton through a straw insert opening of the carton to drink a liquid food.
  • a liquid food in such a paper carton is dispensed or transferred into another container such as a dish or a cup, it is generally difficult to do this through the straw.
  • a liquid food is usually dispensed or transferred into another container by cutting off a corner of the paper carton to make a pour opening and pouring the liquid food through the opening.
  • the opening made in this way drips or dribbles down, and its outer periphery is easily contaminated, which is hygienically problematic.
  • an opening is larger than an opening designed for straw insertion, it is difficult to re-close the paper carton, and preservability of the liquid food is deteriorated.
  • JP-U-64-39253 discloses a pouch which has a straw type pour spout and is adapted to be filled with a beverage (see Fig. 1 of the official gazette). Because this pour spout is not removable but integral with the pouch, it is not reapplicable to other containers.
  • An object of the present invention is to provide a straw which is removably inserted into a container filled with a liquid food, easily pours the liquid food to the last drop, does not drip, is hygienic because the outer periphery of its opening is hardly contaminated, and enables re-closing of the container.
  • the present invention accomplishes the above object by providing a straw 3 adapted to be removably inserted into a press-deformable container 1 through a straw insert opening 2 of the container 1, which is characterized by having a stopping part 4 for stopping itself from being inserted through the straw insert opening 2 and an inlet hole 5 at a position distant from the position of the stopping part 4 by a distance substantially equal to the thickness W of the container-forming material having the straw insert opening 2.
  • the present invention also accomplishes the above object by providing a straw adapted to be removably inserted into a press-deformable container 1 through an insert opening 2 of the container 1, which is characterized by comprising an outer tube 3a, a middle tube 3b, and an inner tube 3c, the middle tube 3b and the inner tube 3c being fitted into the outer tube 3a slidably in their longitudinal direction, the outer tube 3a having a stopping part 4 for stopping itself from being inserted through the insert opening 2 and an inlet hole 5 at a position distant from the position of the stopping part 4 by a distance substantially equal to the thickness W of the container-forming material having the straw insert opening 2, and the inlet hole 5 being opened and closed by sliding at least the middle tube 3b.
  • a straw 3 is a hollow, small-diametered tube having a circular cross-section which is adapted to be inserted into a press-deformable container 1 (e.g., a paper carton) filled with a liquid food (not shown) through a straw insert opening 2 of the container 1.
  • the straw 3 provides a passageway for liquid extending in the longitudinal direction thereof and has its both ends open to form a suction inlet 31 and a pour outlet 32.
  • the straw 3 has its suction inlet 31 side end cut aslant to make a sharp tip.
  • the straw 3 of the first embodiment has a stopping part 4 for stopping itself from being completely inserted through the insert opening 2.
  • the stopping part 4 is a shoulder formed in the middle of the straw 3.
  • the stopping part 4 is formed by making the section nearer to the pour outlet 32 (the section sticking out of the paper carton 1 when the straw 3 is inserted through the insert opening 2) larger in diameter than the insert opening 2 while making the rest of the straw 3 (the section inserted into the paper carton 1) almost equal in diameter to the straw insert opening 2.
  • the straw 3 of the first embodiment has a circular inlet hole or holes 5 connecting to the passageway at a position distant from the position of the stopping part (the shoulder) 4 by a distance substantially equal to the thickness W of the container-forming material having the straw insert opening 2 (the depth of the insert opening 2).
  • the distance that is substantially equal to the thickness W is (W+0.5 to 4.0) mm, preferably (W+1.0 to 2.0) mm.
  • the number of the inlet holes is preferably 2 or 3.
  • the inlet hole 5 is preferably a hole previously made.
  • the straw 3 before use may have easy-to-tear perforations (not shown for the sake of simplicity of drawing) along the along the shape of an inlet hole 5 instead of a previously made hole.
  • the part surrounded by the perforations is torn off or pressed in to make an inlet hole 5.
  • the straw 3 of the first embodiment is used as follows.
  • a paper carton 1 is placed straight up.
  • a sealing piece (not shown) covering the upper face of the insert opening 2 is removed to expose a synthetic resin (plastic) film 6 (see Fig. 2) covering the insert opening 2.
  • the sharp edge of the suction inlet 31 of the straw 3 is pressed to poke the film 6, and the straw 3 is inserted until the surface of the stopping member 4 (the shoulder) comes into contact with the periphery surrounding the insert opening 2.
  • the paper carton 1 having the straw 3 inserted therein through the insert opening 2 is held upside down as illustrated in Fig. 2 with the pour outlet 32 of the straw 3 directed to a container (not shown) into which the liquid food is to be dispensed or transferred.
  • the outer wall of the straw 3 nearby the insert opening 2 is provided with a liquid-tight seal by the inner wall of the insert opening 2 and the film 6 so that the straw 3 may not come off the insert opening 2.
  • the liquid food in the paper carton 1 spontaneously flows by its own weight through the inlet holes 5 and the suction inlet 31 into the passageway and pours from the pour outlet 32 into the container.
  • the paper carton 1 is shape restorable, it is preferred if needed that the paper carton 1 be squeezed with fingers from its both sides in the state shown in Fig. 2 to deform the paper carton 1 thereby to help the liquid food pour smoothly.
  • the paper carton 1 is turned up, and the straw 3 is pulled out of the paper carton. In the next occasion of pouring, the above-described operation is repeated.
  • the straw 3 according to the first embodiment produces the following effects (1) to (7).
  • Fig. 3 represents schematic cross-sections illustrating a straw according to the second embodiment. The same elements as in the first embodiment are given the same reference characters.
  • Fig. 3(a) shows the straw of the second embodiment inserted into a paper carton 1 through an insert opening 2 of the carton 1.
  • Fig. 3(b) shows the straw pulled out from the state shown in Fig. 3(a) until the inlet holes 5 come out of the paper carton 1.
  • the second embodiment has the same configuration as the first one except that the suction inlet 31 of the first one is replaced with a closed end 7.
  • the second embodiment produces the following effect in addition to the effects of the first embodiment.
  • the fluid food in the paper carton 1 can be shielded from the outside air to keep freshness for an extended period of time simply through an easy operation without using a seal for reclosing. That is, the paper carton 1 can be reclosed (the outside air is shut out) simply by pulling up the straw 3 until the inlet holes 5 come out of the paper carton 1 as illustrated in Fig. 3(b). As a result, the residual liquid food, being protected from bacterial contamination, is kept hygienic to have improved preservability.
  • Fig. 4 provides schematic partial cross-sections of a straw according to the third embodiment inserted into a paper carton 1.
  • the same elements as in the first embodiment are given the same reference characters.
  • the third embodiment enables pouring and drinking through a single straw.
  • the straw is composed of an outer tube 3a having a stopping part 4 and a single inlet hole 5 and an inner tube 8 which is rotatably fitted into the outer tube 3a.
  • the inner tube 8 has an inner hole 9 slightly smaller than the inlet hole 5 at a position distant from the position of the stopping part 4 by a distance substantially equal to the thickness W.
  • the outer tube 3a and/or the inner tube 8 are relatively turned to interconnect the inner hole 9 and the inlet hole 5 as shown in Fig. 4(a), and the straw is used in the same manner to produce the same effects as in the first embodiment.
  • the outer tube 3a and/or the inner tube 8 are relatively turned to slide the inlet hole 5 away from the inner hole 9 to block the inlet hole 5 by the wall of the inner tube 8, and then the straw is used in an ordinary manner.
  • Fig. 5 shows schematic partial cross-sections of a straw according to the fourth embodiment inserted into a paper carton 1.
  • the same elements as in the first embodiment are given the same reference numbers.
  • the fourth embodiment enables pouring and drinking through a single straw similarly to the third embodiment.
  • the fourth embodiment is a so-called telescopic straw (a multi-tube straw having a outer tube and an inner tube slidable in the outer tube).
  • the fourth embodiment comprises an outer tube 3a, a middle tube 3b, and an inner tube 3c.
  • the middle tube 3b and the inner tube 3c are fitted into the outer tube 3a longitudinally slidably.
  • the outer tube 3a has a stopping part 4 and an inlet hole 5 at a position distant from the position of the stopping part 4 by a distance substantially equal to the thickness W.
  • the middle tube 3b is slid in the direction indicated by the arrow (downward in Fig. 5(a)) to open the inlet hole 5 as shown in Fig. 5(a).
  • the straw is then used in the same manner as in the first embodiment to produce the same effects as enjoyed in the first embodiment.
  • the middle tube 3b is slid in the direction indicated by the arrow (upward in Fig. 5(b)) (the inner tube 3c is slid downward) to block the inlet hole 5 by the wall of the middle tube 3b as shown in Fig. 5(b), and the straw is used in an ordinary manner.
  • a plastic straw having the same shape as the straw 3 shown in Fig. 1 was made.
  • This straw had a total length of 80 mm.
  • a 57 mm long section from the tip of the suction inlet 31 was a cylindrical tube having an outer diameter of 5 mm; a section from 57 mm to 80 mm away from that tip (the section adapted to stick out of the container) was a cylindrical tube having an outer diameter of 6 mm.
  • the joint between these two tubes different in diameter was a stopping part (shoulder) 4.
  • the straw had two inlet holes 5 having a diameter of 2 mm facing each other at a position about 2 mm distant from the position of the stopping part 4, the distance being substantially the same as the thickness W of the container-forming material having the insert opening 2.
  • Two commercially available paper cartons containing 200 ml of milk and having an opening for straw insertion were prepared. Before poking with a straw, the opening for straw insertion was covered with a film, and the upper side of the opening was sealed with a sealing piece.
  • the two paper cartons were placed straight up, and each of the straws of Example and Comparative Example was inserted through the insert opening.
  • the wall of the straw was kept liquid-tight by the inner wall of the insert opening and the film.
  • the paper cartons were held inverted with the pour outlet 32 down as shown in Fig.2, and pouring milk was received by a cup.
  • the straw of Example enabled efficient emptying of the carton to the last drop.
  • the straw of Comparative Example had to be drawn until the suction inlet 31 came down near the insert opening as the residual amount of milk decreased. Being drawn to such a degree, the straw was so unstable that it was apt to come off the container to cause milk to splash out of the carton. It was impossible with the comparative straw to completely empty the carton to the last drop of milk.
  • the straw of the present invention enables easy pouring the fluid and complete emptying of a container without splashing the fluid out of the container notwithstanding its extremely simple structure.
  • the stopping part 4 is not particularly limited in shape as long as it is capable of stopping insertion of the straw 3 through the insert opening 2. That is, the shape of the stopping part 4 includes not only the shoulder shown in Fig. 6(d), which is adopted in the aforementioned embodiments, but a snap fit shown in Fig. 6(a), a groove fit shown in Fig. 6(b), a stop collar shown in Fig. 6(c), and a protrusion shown in Fig. 6(e). Of these shapes the snap fit of Fig. 6(a) and the groove fit of Fig. 6(b) are effective in preventing fall-off of the straw through the insert opening.
  • the inlet hole 5 is not particularly limited in number and shape as long as it is distant from the position of the stopping part 4 by a distance substantially equal to the thickness W of the container-forming material having the insert opening 2 (the depth of the insert opening 2).
  • a part or the whole length of the section between the stopping part 4 and the pour outlet 32 may be bellows 10.
  • the bellows 10 render the straw extensible and flexible and enable arbitrary positioning of the pour outlet 32 of the straw. This will make it easier to transfer or dispense the fluid food of the container 1 into another container or to drink the fluid food through the straw.
  • the straw of the present invention enables pouring the fluid food to the last drop, does not drip, prevents the outer periphery of its open end from being contaminated to keep the hygiene, and enables easy re-closure of the container.
  • the straw has a two- or three-tube structure, it is made capable of opening and closing its connecting hole and enables both pouring and drinking with only this straw.
