Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a packaging form for a two-tiered straw that is expanded during use.

``Prior Art'' As shown in FIG. 14, a two-stage straw consists of an outer tube 1a and an inner tube 1b slidably inserted into the outer tube 1a. It is used by expanding it by pulling it out. In the two-stage straw 1 of this example, the diameter of the outer tube 1a is reduced until the tip part of the inner tube 1b comes into contact with the inner tube 1b.
b slightly protrudes from the tip of the outer tube 1a. When in use, the two-stage straw 1 is extended by further pulling out the protruding inner tube 1b.

To package the two-tiered straw 1, a packaging method called strip packaging is widely used.

Figure 15 shows the conventional strip packaging for two-tiered straws.
The film is packaged in a strip shape with the films 2, 2 arranged parallel to each other. two films 2,2
The part surrounding each two-stage straw 1 is thermally bonded (hereinafter this part is referred to as the bonded part 2a),
The two-stage straws 1 are individually accommodated in the hollow portions 2b formed thereby. Then, in the adhesive part 2a..., there is a tearing guide 3 for separation consisting of perforations and cuts parallel to the two-stage straw 1...
... are provided, whereby the band-shaped package is divided into individual packages 5....

"Problems to be Solved by the Invention" When using the two-stage straw 1 packaged in this manner, first, the individual packaging body 5 is cut off from the band-shaped packaging body along the separation tearing guide 3.
Next, the films 2, 2 of this individual package 5 are torn and the two-stage straw 1 is taken out, and then the inner tube 1b and the outer tube 1a of the two-stage straw 1 taken out are removed.
Pinch each with your fingers and pull in the opposite direction to stretch straw 1.

As described above, in the conventional strip packaging of the two-tiered straw, when using the two-tiered straw 1, the outer tube 1a and the inner tube 1b must be held directly with fingers, which is unsanitary. There was a problem.

This invention was made in view of the above circumstances,
The purpose of the present invention is to provide packaging for a two-tiered straw that allows the two-tiered straw to be used hygienically.

``Means for Solving the Problems'' In the present invention, in strip packaging of two-stage straws using film, the inner tube of straw 1 is
The above object is achieved by forming the tearing guide 4 in the direction perpendicular to the length direction of the straw 1 from a position near the part where the protruding part b is located and at a distance d from the hollow part 2b. Achieved.

``Operation'' When strip-wrapping a two-tiered straw like this, pinch the inner and outer tubes of the two-tiered straw from above the film while still wrapped, and pull them in opposite directions. , the two-stage straw can be extended at the same time as the film is torn.

``Example'' Hereinafter, an example of the strip packaging of the two-tiered straw of the present invention will be described with reference to FIG. Note that the same reference numerals are given to the same components as in the conventional example described above to simplify the explanation.

In the strip packaging of this example, the two-stage straws 1 are lined up in parallel in a row and are packaged in strips between the films 2, 2. For the films 2, 2, polyethylene film, moisture-proof cellophane, polyethylene-processed cellophane, and various laminate films are used.

In addition to tearing guides 3 for separation provided in parallel with the two-stage straws 1, the adhesive portions 2a are provided with tearing guides 4 for taking out.

The tearing guide 4 for taking out is provided so as to intersect with the length direction of the two-stage straw 1 and extend in the arrangement direction of the two-stage straw 1 . This tearing guide 4 for taking out airtightly seals the hollow portion 2b that accommodates the two-stage straw 1.
It is formed from a position away from the hollow portion 2b, and a slight gap d is provided between the hollow portion 2b and the tearing guide 4 for taking out. It is desirable that the tearing guide 4 for taking out the straw be provided at a position 5 mm or more inward from the edge of the film 2 on the front end side of the two-stage straw 1. If the position of the tearing guide 4 for taking out is less than 5 mm, the inner tube 1
This creates an inconvenience in that it becomes difficult to grasp the tip of b with fingers. In this example of strip packaging, the inner tube 1b of the two-stage straw 1 protrudes from the outer tube 1a by about 10 mm, and the tearing guide 4 for taking out the straw 1a protrudes from the outer tube 1a.
It is provided slightly closer to the tip of the inner tube 1b than the position of the tip of the inner tube 1b. Tear guide for removal 4
can be formed by a slit having an acute angle shape at both ends as shown in FIGS. 2 to 5, or a perforation having a shape as shown in FIGS. 6 to 11.

Next, referring to FIGS. 12 and 13, the two-tiered straw 1 stretched from this strip packaging.
We will explain the operation up to taking out the .

When using a two-tiered straw packaged in this manner, the individual packages 5 are cut off along the tearing guide 3 for separation. Next, pinch both sides of the individual package 5 with the tearing guide 4 for taking out with your fingers. At this time, one finger is used to press the position where the inner tube 1b protruding from the outer tube 1a exists, and the other finger is used to press the position where the diameter-reduced tip portion of the outer tube 1a is present. In this state, when both sides of the individual package 5 are pulled in opposite directions, the films 2, 2 are torn along the tearing guide 4 for removal, and at the same time, the two-stage straw 1 is expanded.

As described above, in the strip packaging of the two-tiered straw of the present invention, when using the two-tiered straw 1, the outer tube 1a and the inner tube 1b are pinched from above the films 2, 2, and the inner tube 1b Since the straw can be pulled out, the two-stage straw can be extended hygienically.

In the strip packaging of the two-tiered straw in this example, the tear guide 4 for taking out is provided with a slight gap d from the hollow part 2b, and the hollow part 2b that accommodates the two-tiered straw 1 is hermetically sealed. Since the two-tiered straw 1 is not contaminated and dust does not enter therein, it is hygienic.

In addition, in the strip packaging of this example, since the tearing guide 4 for taking out is provided slightly closer to the tip of the two-stage straw 1 than the tip of the outer tube 1a, the diameter is reduced when the films 2, 2 are torn. The tip portion of the outer tube 1a, which is difficult to deform, can be pinched, and the two-stage straw 1 can be expanded more easily.

"Effects of the Invention" As explained above, in the two-tiered straw strip packaging of the present invention, in the strip packaging using film, the straw is placed in the vicinity of the protruding part of the inner tube of the straw and from the hollow part. Since the tearing guide 4 is formed from a position separated by a gap in a direction perpendicular to the length direction of the straw 1, when using a two-stage straw, the inner and outer tubes of the two-stage straw can be pinched from above the film. The two-stage straw can be stretched at the same time as the film is torn.

Therefore, with the strip packaging of the present invention, the two-tiered straw can be stretched without directly touching the two-tiered straw, which is sanitary.

Furthermore, since the action of tearing the film and the action of extending the two-stage straw can be performed simultaneously, there is an advantage that the two-stage straw can be easily put into use.

In addition, in the strip packaging of the present invention, the tear guide for taking out is provided with a slight gap from the hollow part, so the hollow part that accommodates the two-tiered straw is airtightly sealed, preventing dust from entering. This also has the advantage of being sanitary as it prevents contamination of the two-tiered straw.
