Abstract

<P>PROBLEM TO BE SOLVED: To provide an opening means for a film package which has made the opening of the film package become easy by working this film packaging material itself without using material except for the film packaging material. <P>SOLUTION: The film packaging body 1 which prepares an opening section 7 at least in one end 1a and has a linear deposit seam 9 which leads from this opening section to the other end 1b is the opening means for the film package which is characterized in that it forms a weakening line 11 on both the sides of the above deposit seam from the above opening section and the inside sections of these weakening lines are made to peel from the remainder of the film package along this deposit seam when opened. This weakening line is preferably formed in both the sides of the above deposit seam from the vicinity of the above opening section. The weakening line is formed of a plurality of perforations. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a means for opening a film package, for example, a means for opening a film package for packaging canned foods, beverages, etc., bottling, etc., tubes such as cosmetics, toothpaste, etc. Is.

  The film package is formed by shrink packaging or other packaging means using a synthetic resin film such as polypropylene, polyethylene, or polyvinyl chloride.

Since it is not easy to open the film package by hand, a tear tape is often attached to the film package as an opening means. Japanese Patent Laying-Open No. 2004-262519 discloses an example of a tear tape.
JP 2004-262519 A

  The tear tape makes it easy to open the film package. However, since the tear tape is an expensive material prepared separately from the film packaging material and is added to the film packaging material, the material cost of the film packaging body is increased.

  In view of such a situation, the present invention is to open a film package that can be easily opened by processing the film packaging material itself without using any material other than the film packaging material. It was made to provide a means.

  The inventor of the present invention pays attention to the fact that the film packaging body often has an opening at one end thereof, and has a linear welding seam extending from the opening to the other end. I came up with the means to open the film package using the.

  That is, the present invention provides the following means for opening a film package.

(1) In a film package having an opening at least at one end and having a linear welded seam extending from the opening to the other end,
A film package having weak lines formed on both sides of the welding seam from the opening, and an inner part of the weak lines being peeled off from the remainder of the film package along the weld seam when opened. Opening means (Claim 1).

(2) In a film package having an opening at least at one end and having a linear welded seam extending from the opening to the other end,
A weak line is formed on both sides of the welded seam from the vicinity of the opening, and an inner part of the weakened line is peeled off from the rest of the film package along the welded seam when opened. Means for opening the package (claim 2).

(3) The weakening line is formed by a plurality of perforations (claim 3).

[Invention of Claim 1]
Since weak lines are formed on both sides of the welded seam from the opening of the film package, when the vicinity of the welded seam in the opening is picked up and pulled by a finger, the inner part of the pair of weak lines in the film package (weakened) The portion between the line and the weak line) is torn from the remaining part of the film package (the outer part of the weak line in the film package), and thereafter the inner part is peeled off from the remaining part along the weld seam. In other words, the welding seam works like a tier tape. Therefore, the film package can be opened very easily. Although the presence of the weld seam is believed to be a drawback of the film package, the inner portions of the pair of weakening lines peel off from the remainder along the weld seam. That is, the present invention utilizes a welded seam that is considered to have such a drawback.

  The opening means for the film packaging body is formed by forming a weakening line on the film packaging material itself without using any material other than the film packaging material. In addition, additional costs such as the material cost of the film package are unnecessary, and the manufacturing cost of the film package can be reduced after all.

[Invention of claim 2]
The weakening line is formed from the vicinity of the opening, and the end of the weakening line does not directly face the opening, so the inner part of the pair of weakening lines is the rest of the film package before tearing by the user. There is no risk of peeling off.
Incidentally, when the end of the weakening line faces the opening, depending on the film packaging material, the inner part of the pair of weakening lines may be peeled off from the remaining part before tearing by the user.

[Invention of claim 3]
Since the weakening lines are formed by a plurality of perforations, the inner parts of the pair of weakening lines are easily and reliably torn from the remaining part of the film package.

  What is shown by the code | symbol 1 is a film package.

  The film packaging body 1 is, for example, a synthetic resin packaging body for packaging canned foods, beverages and the like, bottling, etc., tubes such as cosmetics and toothpaste and other packages. The film package 1 includes a package formed by shrink wrapping using a synthetic resin film such as polypropylene, polyethylene, and polyvinyl chloride, but is not limited to a package formed by shrink wrapping.

  The film packaging body 1 shown in FIGS. 1 to 3 is packaged in a state where a plurality of cans 3, 3.

  The film package 1 shown in FIGS. 4 and 5 wraps tubes 5 such as cosmetics and toothpaste.

  The film package 1 has an opening 7 at least at one end 1a, and has a linear welded seam 9 extending from the opening 7 to the other end 1b. Even if the film packaging body 1 has the opening part 7 in both ends 1a and 1b and has the linear welding seam 9 which extends from the opening part 7 of one end 1a or 1b to the opening part 7 of the other end 1b or 1a. Good.

  Accordingly, in the present invention, the weakening lines 11 are formed on both sides of the welding seam 9 from the opening 7 as the opening means of the film package 1. The weakening line 11 does not need to be formed along the entire length of the welding seam 9, and may be formed only on both sides of the welding seam 9 near the opening 7. In the film package 1 shown in FIGS. 1 to 3, the weakening line 11 is formed only at one end 1 a of the film package 1. In the film package 1 shown in FIGS. 4 and 5, the weakening line 11 is formed only in the portion corresponding to the cap of the tube 5.

  The weakening line 11 is preferably formed from the vicinity of the opening 7 without causing the end 11 a of the weakening line 11 to directly face the opening 7. In other words, it is desirable to form the weakening line 11 while leaving the portion 13 where the weakening line is not formed between the end 11 a of the weakening line 11 and the opening 7. See FIG. 2 and FIG.

  The weakening line 11 is preferably formed by a plurality of perforations 15, 15. See FIG. The perforation 15 is a through hole penetrating the film package 1.

  FIG. 3 shows that when the vicinity of the welding seam 9 in the opening 7 is picked and pulled, the inner portions 17 of the pair of weakening lines 11 and 11 in the film package 1 are torn from the remaining portion 19 in the film package 1. Thereafter, the inner portion 17 is shown peeled from the remaining portion 19 along the weld seam 9.

It is a perspective view which shows an example of the opening means of the film package by this invention. It is a top view same as the above. It is a perspective view which shows the use condition of an opening means same as the above. It is a perspective view which shows another example of the opening means of the film package by this invention. It is a top view same as the above. It is sectional drawing which shows a weak line.
