Description

Straw

Conventionally, the straw is inserted into the straw insertion hole of the carton having the straw insertion hole in a detachable manner, and the fluid food is ingested through the straw. In the case where the fluid food contained in such a carton is transferred to another tableware such as a plate or a cup, it is generally difficult to carry it through the straw. Therefore, the corner of the carton is usually cut to form a discharge opening, and the discharge From the opening, the fluid food is moved to another tableware.

However, the discharge opening formed in this manner is problematic in terms of hygiene because the breakage of the liquid is poor and the dirt easily adheres to the outer circumference of the discharge opening. In addition, since the discharge opening has a larger diameter than the straw insertion hole, it is difficult to reseal the cartons, resulting in poor storage of the fluid food.

On the other hand, Utility Model Publication No. 64-39253 discloses a liquid filling container having a straw-shaped discharge device as a liquid filling container for filling a liquid beverage (see FIG. 1 and the like in the above publication). However, this discharging device is integrally coupled with the liquid filling container and is not detachably coupled, and therefore cannot be converted into another container.

The present invention relates to a straw that is freely inserted into a deformable container such as a carton containing a liquid food such as a liquid drink, a soup of noodles, a marinade of bulgogi, and the like, to be used to pour out the fluid food. In particular, it is possible to easily pour the fluid food to the last drop, and the breakage of the liquid is good, and since the dirt is hardly attached to the outer periphery of the opening end, it is hygienic and the container is excellent in resealability. will be.

It is hygienic and resealability of container is to provide straw.

The present invention is a straw (3) which is detachably inserted into the straw insertion hole (2) of the pressure-deformable container (1) having a straw insertion hole (2), wherein the straw (3) of the straw (3) A gap between the locking portion 4 which prevents the insertion into the straw insertion hole 2 and the thickness W of the container forming material in which the straw insertion hole 2 is formed is formed from the position of the locking portion 4. The above object is achieved by providing a straw which has a through hole 5 at a position in between.

In addition, the present invention is a straw (3) which is detachably inserted into the straw insertion hole (2) of the pressure-deformable container (1) having a straw insertion hole (2), the straw (3) is an outer cylinder (3a) ), An intermediate cylinder 3b and an inner cylinder 3c, and each of the intermediate cylinder 3b and the inner cylinder 3c is disposed along the length of the inner cylinder in the outer cylinder 3a, respectively. The outer cylinder 3a is accommodated in a slidable manner, and the outer cylinder 3a has a locking portion 4 that prevents the insertion of the outer cylinder 3a into the straw insertion hole 2 and the position of the locking portion 4 from the position of the locking portion 4. The through-hole 5 is located in the space | interval substantially equal to the thickness W of the container formation material in which the straw insertion hole 2 was formed, At least by the sliding of the said intermediate cylinder 3b, The said through-hole The above neck is provided by providing a straw, characterized in that the opening and closing is made free (5). It will achieve.

Hereinafter, the straw of this invention is demonstrated, referring drawings for based on the preferable embodiment.

As shown in FIGS. 1 and 2, the straw 3 of the first embodiment includes a container (paper pack) 1 that is capable of receiving fluid food (not shown) and having a straw inserting hole 2. A hollow, thin cylindrical straw which is inserted into the straw insertion hole 2 and has a flow path extending in the longitudinal direction similar to a normal straw, and both ends thereof open and the suction port 31 ) And an outlet 32 are formed, respectively. The end part at the suction port 31 side is cut obliquely and is sharp.

The straw 3 of 1st Embodiment has the locking part 4 which prevents insertion into the straw insertion hole 2. The catching portion 4 is an enlarged end formed in the middle of the straw 3, and protrudes outward from the paper pack 1 when inserted into one end on the discharge port 32 side of the straw 3 (inserted into the straw inserting opening 2). The diameter of the length substantially equal to the diameter of the straw insertion hole 2, and the cylindrical portion having a diameter larger than the diameter of the straw insertion hole 2 is used, and the remaining portion (the portion inserted into the paper pack 1). It is formed by making it into the column shape which has a shape.

Moreover, the straw 3 of 1st Embodiment is the thickness of the formation material of the container 1 in which the straw insertion hole 2 was formed (depth of the straw insertion port 2) from the position of the latching part (extended end) 4. At a position substantially spaced apart from (W), a circular through hole 5 communicating with the flow path is provided. This "interval substantially the same as W" specifically refers to the space | interval of W + 0.5-4.0mm, and the space | interval of W + 1.0-2.0mm is preferable.

In addition, the number of the through holes 5 is preferably 2-3. On the other hand, as shown in Fig. 1 and Fig. 2, it is preferable to use a through hole. However, before the use of the straw 3, the through hole 5 is not opened. Instead, the through hole 5 is used instead. A dotted hole (cutting guide line) (not shown for simplification of the drawing) is formed along the shape of (5), and in use, the portion surrounded by the dotted hole is removed by cutting or pressing to remove the through hole ( You may open 5).

The straw 3 of 1st Embodiment is used as follows.

First, the sheet film of synthetic resin (made of plastic) which peels off the sealing piece (not shown) which covers the upper surface of the straw insertion slot 2, and covers the straw insertion hole 2 in the state in which the paper pack 1 was set up immediately. (6) (refer FIG. 2), presses the sharp edge part of the side of the suction port 31 of the straw 3 to open the said sheet film 6, and the cross section of the locking part (extended end part 4) The straw 3 is inserted until it contacts the edge of this straw insertion hole 2.

After inserting and mounting the straw 3 to the straw insertion hole 2 in this way, as shown in FIG. 2, the tableware 1 is placed upside down and the discharge port 32 of the straw 3 will be moved (not shown). Leave it facing toward). At this time, the outer circumferential wall near the straw insertion hole 2 of the straw 3 is held liquid-tightly through the inner circumferential wall of the straw insertion hole 2 and the sheet film 6, and the straw ( 3) is prevented from coming out from the straw insertion port 2. The fluid food in the carton 1 automatically flows into the flow path through the through hole 5 and the suction port 31 by its own weight and is discharged from the discharge port 32 into the tableware. In that case, when the paper pack 1 has a shape return force, in the state shown in FIG. 2, both sides of the paper pack 1 are pressed (compressed) with a finger as needed, and the said paper pack 1 It is preferable in that it smoothly pours the fluid food.

When it is not necessary to pour out the whole quantity of fluid food, the paper pack 1 is stood up on the way, and the straw 3 is pulled out from a carton. If necessary, the above operation is repeatedly performed.

According to the straw 3 of 1st Embodiment, the following effects [1]-[7] are achieved.

[1] The straw 3 is repeatedly removed and detached by itself and, if necessary, by pressing and deforming both sides of the pack with fingers, such as cotton broth, grilled meat sauce, sauce, ketchup and liquid beverage. It can reliably pour fluid food to the last drop.

[2] The discharge port 32 of the straw 3 has good liquid breakage and is hygienic because hardly any dirt adheres to the outer periphery of the opening end, and after the straw 3 has been removed, the discharge hole 32 is inserted into the straw insertion hole 2. Since the resulting hole is very small, the paper pack 1 can be resealed by closing the hole with a sealing piece or the like, which has the advantage that the sudden deterioration of the contents is prevented.

[3] Since the inside of the paper pack 1 is negative pressure, the breakage of the liquid is good when the pouring out to another container is completed.

[4] As with the normal straw, the fluid food contained in the carton 1 can be ingested (drunk) through the straw 3, in which case, the suction port 31 of the straw 3 can be ingested. In addition to the through hole 5, the fluid food can be easily sucked.

[5] By appropriately adjusting the size of the through hole 5, the fluid having different viscosity and physical properties can be smoothly poured out.

[6] Even if the paper pack 1 is rolled, the inside of the paper pack 1 has a negative pressure, and the outer circumferential wall near the straw insertion hole 2 of the straw 3 and the inner circumferential wall of the straw insertion hole 2. Since the fluid remains liquid, the fluid food does not flow out.

[7] It can be used in small (50 ml) to large (1000 ml) cartons and plastic packaging containers, and the effect can be obtained.

3 is a schematic cross-sectional view of a straw of a second embodiment, wherein like reference numerals denote the same components as in the first embodiment. FIG. 3A shows a state in which the straw of the second embodiment is inserted into the straw insertion hole 2 of the carton 1 having the straw insertion hole 2, and FIG. 3B penetrates from the state shown in FIG. 3A. The straw is taken out until the hole 5 is exposed out of the carton 1.

In the second embodiment, instead of the inlet port 31 of the first embodiment, the inlet port 31 is formed to close the flow path closing portion 7. The other embodiment is configured similarly to the first embodiment. According to the second embodiment, the same effects as those of the above-described first embodiment are achieved, and the fluid food accommodated is merely performed by a simple operation without using a sealing piece for resealing the cartons 1 and the like. It can be cut off from the outside air, and can be stored in a fresh state for a longer period of time. That is, as shown in FIG. 3B, the straw 3 can be sealed (blocked from outside air) by simply pulling out the straw 3 until the through hole 5 is exposed out of the carton 1. Therefore, contamination by the various germs of the contained fluid food is prevented, and the fluid food is maintained hygienically, resulting in improved storage. In particular, seasoning liquids such as noodles broth, marinade sauce, and soy milk can be very good nutrient sources for various bacteria. If the seasoning liquid is left open, the quality deteriorates (rotates) due to bacterial contamination, As it deteriorates, such a function is of great significance.

4 is a schematic cross-sectional view showing a state when the straw of the third embodiment is inserted into the carton pack 1, and the same components as in the first embodiment are denoted by the same reference numerals. According to the third embodiment, it is possible to pour and drink with one straw. As shown in FIG. 4, the inner cylinder is provided inside the outer cylinder 3a having the locking portion 4 and the one through hole 5. (8) is rotatably attached to the inside, and the inner cylinder (8) is penetrated at a position substantially spaced apart from the W from the position of the locking portion (4). It has an inner hole 9 which is slightly smaller than the hole 5.

According to the third embodiment, when the fluid food in the carton 1 is poured into another container, the outer cylinder 3a and / or the inner cylinder 8 are rotated relatively, and as shown in FIG. 4A, the inner hole ( The same effect as 1st Embodiment is achieved by using 9) and the through hole 5 continuously, and using it similarly to 1st Embodiment. In the case of drinking the fluid food, the outer cylinder 3a and / or the inner cylinder 8 are rotated relatively, and as shown in FIG. 4B, the through hole 5 is shifted from the inner hole 9. After covering the through-hole 5 with the wall surface of the inner cylinder 8, it uses like a normal straw.

FIG. 5 is a schematic cross-sectional view illustrating a state when the straw of the fourth embodiment is inserted into the carton 1, and the same components as in the first embodiment are denoted by the same reference numerals. Like 4th Embodiment, 4th Embodiment also makes it possible to pour and drink in one straw. The fourth embodiment is a so-called telescopic straw (multi-stage straw consisting of an outer cylinder and an inner cylinder capable of sliding inside the outer cylinder), and as shown in FIG. 5, the outer cylinder 3a and the intermediate cylinder 3b. And an inner cylinder 3c, and the intermediate cylinder 3b and the inner cylinder 3c are respectively accommodated in the interior of the outer cylinder 3a so as to be slidable in the longitudinal direction. The outer cylinder 3a has one through hole 5 at a position at substantially the same distance as the W from the position of the locking portion 4 and the locking portion 4. .

According to the fourth embodiment, when the fluid food in the carton 1 is poured into another container, as shown in FIG. 5A, the intermediate barrel 3b is slid in the direction of the arrow (downward in FIG. 5A), and the through hole 5 ), The same effect as in the first embodiment is achieved by using the same as in the first embodiment. In addition, when drinking a fluid food, as shown in FIG. 5B, the intermediate | middle cylinder 3b is slid in the direction of an arrow (upward in FIG. 5B) (inner cylinder 3c is slid downward), and the through-hole 5 ) Is covered with the wall surface of the intermediate barrel 3b, and then used in the same manner as a normal straw.

Hereinafter, although an Example of this invention and the test example which shows the effect of this invention are given and this invention is demonstrated more concretely, this invention is not restrict | limited at all by this Example.

EXAMPLE

A plastic straw of the same shape as the straw 3 shown in FIG. 1 was manufactured, and it was set as the straw of an Example. This straw has a total length of 80 mm, and a portion extending from the end on the suction port 31 side (part inserted into the inside of the container) has a cylindrical shape with an outer diameter of 5 mm, and a portion extending from 57 mm to 80 mm from the end (outside of the container). The part which protrudes into the shape becomes a cylindrical shape with an outer diameter of 6 mm, and the joining part of the cylinder from which these external diameters differ is used as the locking part (extended end) 4. Further, a through hole having a diameter of 2 mm from the position of the catching portion 4 at a position having an interval of about 2 mm substantially equal to the thickness W of the container forming material in which the straw insertion hole 2 of the carton 1 is formed. (5, 5) is formed so as to face each other.

[Comparative Example]

The straw of the same structure as the straw of the said Example was produced except not having the through-holes 5 and 5, and it was set as the straw of a comparative example.

[Test Example]

Two commercially available cartons with straw insertion holes and containing 200 ml of milk were prepared. On the other hand, the straw insertion hole is covered with the sheet film before the straw is inserted and mounted, and is not opened. A sealing piece is attached to the upper surface of the straw insertion hole.

The two cartons were placed upright, and the straws of the examples and the comparative examples were inserted and mounted in each of the straw inserting holes, respectively (in this case, the outer circumferential wall of the straw is formed through the inner circumferential wall of the straw insertion hole and the sheet film. Kept liquid).

And as shown in FIG. 2, the carton was turned upside down, the discharge outlet 32 of the straw was left to face downward, and the discharged milk was received by the cup.

As a result, according to the straw of the Example, it was possible to efficiently pour milk to the last drop. On the other hand, in the straw of the comparative example, in accordance with the decrease in the remaining amount of milk, the suction port 31 of the straw must be pulled down to the vicinity of the straw insertion hole, and the straw is unstable at such a lowered position from the container. It is easy to fall off, and there is a danger that milk will fly out of the carton. In addition, in the straw of the comparative example, the milk could not be completely poured to the last drop.

From the above results, according to the straw of the present invention, it can be seen that despite being a very simple structure, it is possible to easily pour out the fluid in the container without scattering it to the outside of the container.

The straw of this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning.

For example, the catching part 4 should just be able to prevent insertion of the straw 3 into the straw insertion hole 2, The shape is not specifically limited, Shown in FIG. 6D employ | adopted in the said embodiment. In addition to the enlarged end as described above, the fitting end as shown in Fig. 6A, the fitting groove part as shown in Fig. 6B, the blade bottom as shown in Fig. 6C, the bulging part as shown in Fig. 6E may be used. Among these, the fitting end of Fig. 6A and the fitting groove portion of Fig. 6B have an effect of preventing the straw from being detached from the straw insertion hole.

In addition, the through-hole 5 is spaced apart from the position of the catching part 4 substantially equal to the thickness (depth of the straw insertion opening 2) W of the container formation material in which the straw insertion hole 2 was formed. What is necessary is just to form in the position, and the number and shape in particular are not restrict | limited.

For example, as shown in FIG. 7, the bellows part 10 can be made part or all between the locking part 4 and the discharge port 32 of a straw. By forming the bellows portion 10 in this manner, the straw is freely stretched and bent in the bellows portion 10, and the discharge port 32 of the straw can be easily adjusted to an arbitrary position. The effect of moving the fluid food to another tableware or drinking the fluid food more easily is achieved.

According to the straw of the present invention, it is possible to pour the fluid food up to the last drop only by inserting it into a container containing the fluid food, and the breakage of the liquid is good, and almost no dirt adheres to the outer periphery of the opening end. It is hygienic because of its hygienic and excellent resealability.

In addition, by setting the two-stage or three-stage straw, it becomes possible to give the straw itself a function of opening and closing the through hole, and to pour and drink in one straw.
