2. Description of the Related Art As is well known, as the industry prospered and the life of citizens improved, various changes in the lifestyle began to appear, and various changes were seen in the lifestyle of clothing, food and housing. With the advancement of women's workplaces and diversification of lifestyles, for example, various changes in eating habits have been observed, and not only eating habits for home cooking but also eating habits by eating out at restaurants etc. However, so-called snacks and fast foods have become a large proportion of the eating habits due to the complication of private life and corporate activities, and many instant and instant eating modes are also adopted. Is starting to appear.

Of these, for example, sandwiches and rice balls are sought at stands, fast foods, etc.
Brick type beverages such as those shown in Figure 1 and beverages such as milk 1
For students and office workers, the form of simply eating for food has certainly become a citizen.

As shown in FIG. 7, a beverage 1 such as juice or milk of the brick type is made of a synthetic resin by using a diagonal area of a side surface 2'of a container 2 made of a predetermined paper or the like. The straws 3 and the like are integrally attached so as to be wrapped by the film sheet 4, and are distributed as one unit,
At the time of drinking, the straw 3 together with the film sheet 4 is removed from the container 2, and a sticker sheet or the like attached to the drinking port 5 provided on one side of the upper surface of the container 2 by lining or the like is attached to the tip of the straw 3. In general, it is pierced by an obliquely cut insertion port 3 ″, torn, inserted into the inside and sucked, and because of the structure of the container 2 and the straw 3, a diagonal region of the side surface 2 ′ of the container 2 is formed. Due to a conflicting relationship, the straw 3 is of a double tube type and is in a short state when it is integrated into the diagonal area through the film sheet 4, and when drinking, it is fixed to a predetermined length by relative extension of the inner and outer tubes. However, in many cases, the straw 3 is attached in a unit length due to structural complexity and handling problems.

By the way, in the straw 3 of the unit length, as shown in FIG. 7, the sticker sheet 5 ′ lined on the drinking mouth 5 of the container 2 is pierced by the insertion port 3 ″ of the straw 3. When sucking and drinking, the peripheral surface of the straw 3 is circularly associated with the drinking mouth 5 as shown in FIG. Poorly, if the outer shape of the container is deformed due to an increase in negative pressure in the container 2, or if it takes time to lengthen the container, the straw 3 may fall into the container 2 from the drinking opening 5 and may not be able to drink. There is.

To cope with this, as shown in FIG. 5, a stopper 6 is formed in the vicinity of the suction port 3'of the straw 3 in the form of a knob to prevent the straw 3 from dropping from the drinking port 5 into the container 2. Such a device has been devised and widely provided by the applicant.

However, in the straw 3 having such many merits, the structure having the stopper 6 makes it difficult to form a double tube type straw of the relative expansion / contraction type. As shown in FIG. In many cases, there is no straw 3 and the film sheet 4 is integrally attached to the side surface 2'of the container 2 so that the film sheet 4 is wrapped around the diagonal area of the side surface 2 ', and it is very popular because of its reasonable usability. It was

[0008]

However, in order to integrally attach such a straight type straw 3 to the side surface 2'of the container 2 via the film sheet 4, in order to improve process efficiency, an automated process or a semi-finished process is used. Since an automated process is adopted, the ends of the suction port 3 ′ and the insertion port 3 ″ may stick out from the diagonal area as shown in FIG. In the vending machine of No. 3, there was a problem that the excess amount was caught, there was a drawback that it interfered with the device and dropped, and the suction port 3 ′ was damaged when taking out.

Since the straight straw 3 is assembled with the film sheet 4 in the diagonal region of the side surface 2'of the container 2 for manufacturing, the stopper 6 portion is sucked into the suction port 3'when the diagonal region is fully attached. There is a demerit that the suction port 3 ′ is shortened in the vicinity of, and it becomes difficult to suck the beverage.

Further, when the stopper part 6 partially enters the container 2 through the drinking spout 5, there is a drawback that the stopper part 6 falls inside as it is.

OBJECT OF THE INVENTION The object of the invention of the present application is to integrally attach a film sheet to the diagonal area of the side surface of a brick type container while making full use of the merit of the straight straws based on the above-mentioned prior art. The technical problem that should be solved is the problem of various troubles caused by the protrusion of the unexpected suction port and the insertion port from the top of the container due to the above, and while taking advantage of the straight straw, While sticking to the diagonal area as much as possible through the film sheet, the suction port can be kept long enough when sucking beverages,
Moreover, it is intended to provide an excellent straw structure which is useful for the field of using the drinking and drinking technique in the food industry by allowing smooth drinking so as not to drop inside the drinking mouth.

[0012]

In order to solve the above-mentioned problems, the structure of the invention of the present application, which is based on the above-mentioned object, has a film sheet on the side wall of a container of brick type or the like. In a straight straw that is integrally attached via the like, for example, when the straw is inserted into the drinking mouth of the container and sucked, the portion near the drinking mouth of the general part so that the straw does not fall into the container A bellows of a slightly larger diameter is provided, the straw is attached to the diagonal region of the side surface of the container so as to be fully filled, and at least one of the front and rear portions of the straw of the suction port has at least one small bellows. 1
A unit step is provided, and the bellows are attached to the diagonal part of the side wall of the container in a reduced state so that the suction port and the drinking port do not protrude from the top of the container and avoid trouble with the vending machine. Thus, when sucking a beverage and removing the straw from the side wall of the container, the bellows is sufficiently expanded so that the suction port portion of the straw is in a sufficiently expanded state so that the straw is discharged from the drinking container into a container. In the case of an old person or a sick person, it is possible to bend the straw through the bellows appropriately and drink in an optimal state.In this case, the large bellows may stop the straw due to the stopper action. Instead, it is a technical measure that allows smooth suction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the invention of this application is shown in FIGS.
The explanation is based on the following.

It should be noted that parts that are the same as those in FIG. 4 and subsequent figures will be described using the same symbols.

In the embodiment shown in FIGS. 1 and 2, reference numeral 31 (FIG. 2 shows the extended posture of FIG. 1) is a straw which is the center of the gist of the present application, and the insertion port 9 is formed at the time of its manufacture. A bellows 8 having a diameter larger than that of a straw of a general part having a stopper function for one step of fall prevention is formed near the suction port 3'at a base end, and is formed from the bellows 8 portion. A bellows 8 ′ having a diameter smaller than that of the straw of a predetermined general portion is continuously formed with a step toward the insertion port 9 direction.

As shown in FIG. 2, the bellows 8 and 8'have peaks and valleys so that the bellows 8 and 8'can be extended about 2 to 2.5 times in their extending postures. It is formed into a type that is embedded in.

The straw 31 is attached to a diagonal area of the side surface 2'of the brick type container 2 of the general embodiment shown in FIG. 3 through the film sheet 4 in a substantially full length with the bellows 8,8 'shortened. It is molded so that it can be done.

The bellows 8 are formed so that the peaks thereof are recessed in the valleys, and the valleys are uniformly formed in the extended posture shown in FIG.

In the above-mentioned structure, the straw 31 is shortened with respect to the diagonal region of the side surface 2'of the brick type container 2 in a short state so that the bellows 8 and 8'intrude into the valleys at the time of manufacturing the straw 31. As shown in FIG. 3, the film sheets 4 are integrally attached to each other as much as possible, and in this attachment state, although the distance between the suction port 3'and the insertion port 9 is short, each end portion is a container. It does not stick out from the top of No. 2 and is automatically attached to the regulated posture state and does not get caught in the mechanical section of the vending machine, drop off or be damaged.

Therefore, the brick type 1 stored in the stand or the like of the vending machine has no possibility of causing troubles such as the suction port 3'and the insertion port 9 being deformed due to catching or the like.

When sucking the beverage inside the container 2, the straw 31 is peeled off and taken out together with the film sheet 4 from the diagonal region of the side surface 2'of the container, and the bellows 8 and 8'part are taken from the posture shown in FIG. When extended to the posture shown in FIG. 2, the bellows 8 and 8 ′ are integrally stretched by a factor of 2 to 2.5, so that the straw 31 (particularly the suction port 3 ′ portion) is also sufficiently stretched during suction. It is made into a length, pierces and tears the sealing paper lined with the mouthpiece 5 provided at the top of the container 2 with the insertion port 9 and further inserted, and the suction port 3 '(by the large-diameter bellows 8 Beverages inside the container 2 are sucked in a predetermined manner by sucking a predetermined amount via (internal fall is prevented).

At this time, the large-diameter bellows 8 interferes with the drinking mouth 5 and the dropping of the straw 31 from the bellows 8 into the container 2 is reliably prevented.

Further, the small-diameter bellows 8'in the preceding stage following the large-diameter bellows 8 bends in a predetermined manner to exhibit smooth suction.

In this embodiment, the diameter of the peak portion of the bellows 8'is smaller than the outer diameter of the general portion of the straw 31 before and after the peak portion (thus, the diameter of the valley portion is smaller, and the straw 31 is smaller). When the general part is inserted and meets the drinking mouth 5, the bellows 8'is smoothly inserted so as not to interfere with the drinking mouth 5. It is a mode).

In this embodiment, the bellows 8 and 8'are made to have a sufficient length so that the bellows 8 and 8'do not fall inside the drinking mouth 5.

As described above, the bellows 8 and 8'are formed so that the peaks of the bellows fit into the valleys. However, the bellows 8 and 8'are formed so that the extended posture and the bent posture are always maintained. There is something.

Needless to say, the embodiment of the invention of this application is not limited to the above-mentioned embodiment. For example, various modes can be adopted such that the number of unit steps of the front and rear bellows is three or more. Is.

Further, the straw 31 to be applied is not only attached to the side surface 2'of the brick type container 2 by the film sheet 4 in a diagonal area, but also applied to a straw which is used independently of the container. Of course, you can do it.

[0029]

As described above, according to the invention of this application, in the straw which is basically integrally attached to the diagonal region of the side surface of the brick type container, the bellows for preventing the internal fall of the container into the drinking mouth. In a straw structure having
A predetermined number of large-diameter bellows are formed in the vicinity of the suction port, and a small-diameter bellows is continuously formed next to the bellows. Even in a mode in which the area is shortened and is integrally attached to the container through the film sheet, and when the straw is always automatically attached to the container, the diagonal area is attached as shown in FIG. , The suction port and the insertion port of the straws at both ends stick out from the top of the container, and the protrusions may cause the mechanism part to be caught or deformed in the stand of the vending machine. There is no trouble, etc., and while it is attached to the diagonal area with a sufficient unit length, it can extend the bellows during suction and make the drinking mouth a sufficient length, and has a stopper function of the bellows. By structure Even for straws that are straight and have sufficient strength and rigidity that heavy tube type slide straws cannot be used, they have the advantage of being attached to the side of the container and having the freedom to have a predetermined length when drinking. .

Moreover, since it has the bellows, it has an advantage that it is easy to use in a bent manner when an elderly person or a physically handicapped person drinks.

By making the diameter of the peak portion of the bellows smaller than the diameter of the straight portion of the straw before and after the bellows,
There is an advantage that the bellows can be smoothly inserted without interfering with the drinking mouth of the container, and the bellows portion can be hooked on the drinking mouth and prevented from easily falling inside.
