Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package for a rod-shaped object such as a drinking straw, and a method for manufacturing the same.

2. Description of the Related Art Conventionally, a package shown in FIG. 1 has been known as a package for a rod-shaped object such as a drinking straw. This consists of two plastic strip-like films 1.2 having a certain width stacked one on top of the other, and rod-like bodies 3 arranged in parallel between the two films at a certain interval. , 2, with both side edges 5 welded together.

In such a conventional packaging body, gaps exist in the portion indicated by reference numeral 6 among the portions on both side edges 5 of the films 1 and 2 where the rod-shaped body 3 is located, and in the portion 7 between the dotted welded portions 4. .

As shown in FIG. 2, this package is generally cut into pieces 8 each enclosing one rod-shaped body, and then used by adhering them to a beverage container 9. When used in this way,
The beverage container 9 is cooled because it is stored in a refrigerator, but
Since the package 8 attached thereto has the voids 6 and 7 as described above, liquid such as moisture permeates through these voids 6 and 7 and reaches the surface of the rod-shaped body 3. Once liquid has entered the package in this way, it is almost impossible to remove it. This is not desirable because if liquid enters the inside for a long period of time (theoretically, the longest is about 90 days), this liquid will rot and become unsanitary.

The present invention has been made in view of the above-mentioned circumstances, and includes a packaging body in which the entire periphery of a rod-shaped body is joined to prevent liquid from entering the vicinity of the rod-shaped body during storage; An object of the present invention is to provide a method for manufacturing a package for forming a package.

The packaging body of the present invention and its manufacturing method will be described in detail below based on one embodiment shown in the drawings. Figure 3 shows
11.12 is a perspective view showing a first embodiment of the package of the present invention (shown upside down compared to the conventional example in FIG. 1);
13 is an upper film and a lower film respectively made of a synthetic resin material; 13 is a recess in which a rod-shaped body such as a straw is enclosed;
Reference numeral 4 indicates a joint (shaded portion) where the upper and lower films are joined by means such as thermal welding, and 15 represents another joint where the upper and lower films are joined in a dotted manner for fixation. Each package 10 in which a rod-shaped body formed in such a shape is housed in each recess is continuous and integrated.

When used, this continuously wrapped package is cut at a portion 16 and separated into individual packages 10, which are then glued and attached to a beverage container for use, as in the conventional example shown in FIG. Ru. Each package 10 has a recess 13 as described above.
Since the rod-shaped body is housed inside the package 100 and the periphery of the package 100 is completely joined, it is in a sealed state and there is no risk of liquid etc. infiltrating into the rod-shaped body.

FIG. 4 is a perspective view of another second embodiment of the package of the present invention. In this embodiment, a portion (
A joint portion 14 is provided in the shaded area, and dotted joint portions 15 are further provided around the joint portion 14. In this second embodiment, each package is divided and used by cutting along the recess 13 and the intermediate portion 17 of the recess 13. This second
Also in the embodiment shown in FIG.
Since the rod-shaped body is sealed by the joint 14 formed in the vicinity of the rod-shaped body 3, liquid or the like will not enter the rod-shaped body.

Above 1. Of the second embodiments, in the first embodiment, the closest part of the rod-like body is not joined, so it is easy to push one end of the rod-like body, break through the film, and take it out of the package. . However, when a continuous package is cut and separated into individual packages 10, the sealing may become incomplete due to misalignment of the cutting position. In the case of the second embodiment, it is not as easy to push the bar and break through the film as in the first embodiment. However, when a continuous package is cut and separated into individual packages, even if the cutting position is slightly shifted, the sealing will not be incomplete.

Next, a method for manufacturing a package according to the present invention will be explained using an example in which the package according to the first embodiment is manufactured.

5 and 6 are views showing a part of the apparatus for implementing the manufacturing method of the present invention, FIG. 5 is a perspective view, and FIG. 6 is a sectional view along the mold movement direction. . In these figures, 21
22 is a concave part formed in the center of each mold, 0 is a convex part formed on the periphery of the top surface of each mold, 24J/i is a concave part on the top surface of each mold. Numerous dot-like protrusions are provided between n and the protrusion device, and 5 is a heating roller with a smooth surface.

A method for manufacturing the package of the present invention using such an apparatus will be described. Each mold 21 is fed from right to left as indicated by arrows in the drawing. First, the lower film 12 is supplied to the upper surface of the mold 21 and is moved together with the mold 21 in the direction of the arrow. At part A in FIG. 6, a suction device (not shown) sucks a portion of the recess n, thereby causing the lower film 12 to adhere to the inside of the recess 22.

The concave portion 13 shown in FIG. 3 is formed. Next, at part B, the rod-shaped body 3 is inserted into the recess 22 of the mold 21 (recess 1 of the film).
3), and further, at a portion C, the upper film 11 is supplied so as to cover the lower film 12. If you continue to move in the direction of the arrow, the mold 21. Rod-shaped body 3. Upper and lower film 11.1
2 reaches below the heating roller 5.

Here, the upper and lower films 11 and 12 are the convex portions O and 2 of the mold 21.
Only the portion 4 is pressed and welded by these and the heating roller 5. In this way, while the moxibustion mold ρ sequentially moves in the direction of the arrow, the child film 12. Rod-shaped body 13. The upper film 11 is supplied and welded by the heating roller 5 to form a continuous package as shown in FIG.

As described above, since the packaging body of the present invention is provided with joints at positions surrounding the recesses in which each rod-shaped body is housed, the rod-shaped bodies are completely sealed, and therefore there is no risk of moisture infiltrating into the rod-shaped bodies.

Further, according to the method for producing a package of the present invention, a concave portion for forming a storage portion for the rod-shaped body is provided in a mold, and a convex portion is provided to surround this concave portion, and the mold is welded and joined by a heating roller. The package of the present invention described above can be easily manufactured.
