この発明は、飲料用ストロー端部の縮径装置に
関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a diameter reducing device for the end of a drinking straw.
（従来の技術）
飲料用容器に付着させるストローは、飲用の際
に容器内に落ち込んでしまわないよう、容器の深
さよりも長い必要がある。公知の一本ストローで
は、容器にストローを突き刺しても、容器から出
る部分が僅かである為、容器内飲料が飲み難い。
この難点を解消する為、ストローが容器に付着し
ている状態では短く、容器に突き刺す際に長くし
て、突き刺した状態で容器から突き出ている部分
を長くするよう、伸縮自在な二重ストローが開発
された。(Prior Art) A straw attached to a beverage container needs to be longer than the depth of the container so that it does not fall into the container during drinking. With a known single straw, even if the straw is stuck into the container, only a small portion comes out of the container, making it difficult to drink the beverage in the container.
To solve this problem, we created a double-stretch straw that is short when it is attached to the container, becomes longer when it is stuck into the container, and becomes longer when the straw sticks out from the container. It has been developed.

防止するようにしてある。 That is, as shown in FIGS. 7 and 8, this double straw consists of a thin inner straw 1 and a thicker outer straw 2. The inner straw 1 is inserted into the outer straw 2, and the inner straw 1 is inserted into the outer straw. The inner straw 1 is made longer than the outer straw 2 so that it protrudes beyond the tip of the straw 2. The tip of the inner straw 1 is cut diagonally to form a sharp point 3 for convenience of sticking into a container. When the inner straw 1 is pulled out from the outer straw 2 and extended, a reduced diameter portion 4 is formed at the tip of the outer straw 2 to prevent the inner straw 1 from slipping out from the outer straw 2. An enlarged diameter portion 5 is formed on the side, and the reduced diameter portion 4 and the enlarged diameter portion 5 are configured to engage with each other. Further, a tapered portion 6 is formed at the tip of the reduced diameter portion 4 to prevent wobbling at this engaging portion when the straw is extended.
更に図面に示すように外側ストロー２の基端側

ー８と内側ストロー１の拡径部とが係合し、内側
ストロー１が再び外側ストロー２内に収縮するこ
とのないようにしてある。 Furthermore, as shown in the drawings, a reduced diameter portion 7 is also formed on the proximal end side of the outer straw 2 to prevent the inner straw 1 from slipping out from the proximal end side of the outer straw 2. Reduced diameter part 4
A stopper 8 protruding inward is formed at a nearby position, and when the double straw is extended, this stopper 8 and the enlarged diameter portion of the inner straw 1 engage, and the inner straw 1 contracts again into the outer straw 2. I've made sure there's nothing to do.
上記の構成からなる二重ストローを生産するの
に、これを手造りするのは容易であるが、機械的
に多量生産並びに自動生産するのはきわめて困難
であつた。 Although it is easy to produce the double straw having the above structure by hand, it is extremely difficult to produce it mechanically in large quantities or automatically.

ができない。(Problems to be Solved by the Invention) With the above-mentioned known straw end diameter reducing device,
Although the tip of the straw can be mechanically reduced in diameter by an automatic machine, contributing to the automatic production of double straws, the known device is simply provided with a hollow female mold that receives the end of the straw. Therefore, high dimensional accuracy of the reduced diameter end of the straw cannot be obtained.

The enlarged diameter die 18 is opposed to a holding groove formed in the straw holding drum 16 to hold the straw, and is configured to rotate in synchronization with the rotation of the straw holding drum 16. Further, the diameter-reducing mold 17 and the diameter-expanding mold 18 are heated by electric heaters to facilitate molding of straws.
In Fig. 6, reference numerals 24 and 24 are immovable cam members, and actuating pieces 2 for the straw molding molds 17 and 18 are attached to the cam surface of the cam members.
The cam followers 26 of the straw molds 17 and 18 are brought into pressure contact with each other, and as the straw molding molds 17 and 18 rotate, they engage and disengage from the ends of the inner and outer straws 1 and 2. That is, when engaged, the inner and outer straws 1, 2
The end of the straw is molded to release the straw upon removal.

置に突出させる。 In the apparatus configured as described above, the inner straw 1 and the outer straw 2 are each transferred from the conveyance device 11 to the straw holding drum 16. Therefore, these straws move as the holding drum 16 rotates, and are held down by the rubber belt 19 midway so that they do not move. At the same time, as the holding drum 16 rotates, the rotary plate 22 that holds the straw end diameter reducing mold 17 constituting the apparatus of the present invention also rotates, and the diameter reducing mold 17 is moved between the cam member 24 and the actuating piece 25.
It is caused to project from the first illustrated position to the second illustrated position by the cam action.

At this time, in particular, in the device of the present invention, since a core 30 is provided in the hollow female mold 27, the tapered part 6 at the end of the straw is restricted from narrowing inwardly by the core 30, and can be accurately There will be strict size regulations. Thereafter, this diameter-reducing mold 17 is pulled in and returned to its original position by a cam action, and the straw 2 with a molded end is formed.
is passed to a straw delivery device.

い。 In the embodiments described above, the ends of the inner and outer straws are formed in a combination, but the diameter of a single straw may be reduced. Further, although a spiral rod is used as the straw conveying device, this is not limited to a spiral rod, and any device that can convey the straws at a constant interval may be used. Furthermore, although the straw holding member is shown as a holding drum, this does not need to be a drum, and any material that can hold the straw can be used.
Although the diameter-reducing mold is moved in and out, it is also possible to fix the diameter-reducing mold and move the straw in and out.
