Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package useful for protecting and taking out stored items by devising the position of an opening means for taking out stored items.

Conventionally, for example, Japanese Utility Model Application Publication No. 125789/1989 discloses a gazette-like bag in which perforations are provided on the flat surface of the bag in order to take out stored items. The stored items can be taken out by tearing the perforations, but if the stored items are in the form of lumps, the opening will not open wide and the stored items will get caught on the edge of the opening. It is difficult to take out the bag, and when the stored items are repeatedly taken out, the opening part is located on the top surface, so dust and the like accumulate during storage and get into the bag, which is not desirable. Furthermore, there is also the inconvenience that the pattern provided on the surface is cut by the opening.

The present invention aims to solve the above-mentioned problems and provide a more preferable packaging body, in which intermittent cut lines such as perforations are continuously provided at the folded inner ends of the gussets provided on both sides of the tube. The items are then stored in the tube, and both ends of the tube are closed and packaged in a gusset shape.

Hereinafter, the present invention will be explained in detail together with examples.

First, as shown in FIG. 1, the inner end of a gusset 2 formed on one or both sides of a flexible tube 1 made of a single synthetic resin or a laminated material with other materials and folded inward. Provide perforation 7,
This is a package 35 in which a stored item 36 is stored in the tube 1 and both ends are sealed to form a gusset shape.

The tube 1 used in the package of the present invention has gussets folded inward on both sides as shown in FIG.
A perforation 7 is provided at the inner end of this gusset 2,
For example, the intermittent cut line such as this perforation can be
It is made by the method shown in the figure. First, make a gusset on one or both sides of the tube, fold it inward, and then place the rollers 3 side by side at an appropriate distance.
and roller 4 under tension. When the sawtooth 5 supported by a rotating mechanism is inserted between the gussets 2 of the tube and the flat tube is transferred so as to come into contact with the inner end 6 of the gusset, the perforations 7 are formed while the sawtooth rotates. Can be attached one after another.

In the one shown in the figure, the sawtooth 5 is attached to the rear part of the guide body 11 using wood, metal, plastics, or other suitable material so that the teeth slightly protrude, and the support 13 is used to frame the sawtooth. etc. is fixed. When this guide is inserted between the gussets 2 of the tube, the front corner comes into contact with the inner end 6 of the gusset and then it is guided to the rear sawtooth, so the perforations are made straight along the inner end. It will be done.

Since the present invention has the above-described configuration, it is easy to pinch both ends of the gusset on the side of the tube, and when you pinch it and pull it to both sides, the cut line is provided at the fold line at the inner end of the gusset. It is torn smoothly along the fold line, does not bend to the side or tear irregularly, and creates an opening of the necessary size, allowing the stored items to be easily taken out as needed. After taking it out, if you pull both ends of the gusset in the longitudinal direction, the gusset will be folded inward.
Both edges of the opening abut against each other inwardly of the bag, and are naturally closed, thereby trapping and protecting the stored items within the bag. Since the opening is on the side rather than the top, there is less dust or dirt getting inside, and even once opened, the contents are kept clean and hygienic until the next use. Further, even during handling of the product, such as transportation, sales, and display, the score line will not be inadvertently torn. Even when these packages are stacked, the score lines are not blocked, so a slight amount of ventilation is achieved, which is more preferable for items that require ventilation. In addition, the cut lines that almost coincide with the fold lines at the inner edge of the gusset are not very noticeable, so they do not get in the way when displaying letters, patterns, or other types of display, and they are usually placed on the top surface where the main display is displayed. Since there are no cut lines, the display is not divided, further improving the display effect.
