Abstract

PURPOSE:To easily use without spilling out contents at the time of use by a method wherein two laminate films are overlaid, three sides are heat-sealed with one side left while one directional tip is heat-sealed like a bottle neck and scores for tearing are provided in a range that the scores do not reach directly the neck part. CONSTITUTION:Two sheets of barrier laminate films 1 are overlaid and three sides are heat-sealed while one of the heat-sealed sides is heat-sealed 2 in a bottle neck shape to mold a bag A to make it a mouth 3. On the heat-sealed part 2 of the bag mouth 3, scores 4 are provided in a range that they do not pass through the mouth 3. A side which is not heat-sealed of the barrier laminate film 1 is opened to permit paste or liquid to be filled and then sealed by heat-sealing after filling is completed. When the contents are to be used, the scores 4 are torn to open the mouth 3 so that the contents can be taken out. After use, the bottle neck part is folded and stored by being interposed with a clip or the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to pasty products such as anointing products, cosmetics, ketchup, mustard, miso, etc., as well as liquid products such as oils, water, juice, soybean oil, etc. Regarding the storage bag to be filled.

[Prior Art] The above-mentioned paste-like materials and liquid materials are generally filled and stored in bottles or tubes and sold as commercial products.

[Problems to be Solved by the Invention] The reason behind the adoption of the above-mentioned storage formats such as bottles and tubes is that during use, the filled contents are taken out in small quantities through the spout or squeeze spout, and over-dispensing is prevented. There are conveniences such as being able to do so. However, bottles and tubes require special molding machines, and because they are shaped like containers, they lack flexibility. Therefore, after filling and storing the contents, storage in a warehouse or handling such as transportation becomes bulky and distribution costs increase, so there is room for improvement. On the other hand, there are storage bags made of various types of plastic films that are lightweight, flat, and flexible, and are suitable for the purpose of use. It was difficult to handle.

[Means for solving the problem] The present invention was devised to solve this problem in view of the above-mentioned circumstances, and it does not spill outside during use and is easy to use without being bulky for storage and transportation. This product is provided for the purpose of: stacking two laminate films, heat sealing on three sides except for one, and heat sealing the tip of at least one direction of the film by squeezing it into a bottleneck shape,
Furthermore, the storage bag is provided with perforations for tearing within a range that does not directly touch the neck, and is characterized by being flexible and having a bottle or tube function.

[Example] Next, an example of a pasty or liquid material storage bag according to the present invention will be described based on the drawings.

1 is a barrier laminate film, and the laminate film is made of, for example, PET, 10PE, 1/AM, /P.
E,,/LLDPE,,is constructed.

Layer two layers of this barrier laminate film 1trLLDPE with their faces facing each other, and then
As shown in FIG. The bag body A is formed so as to form the aperture opening 3.

In addition, the heat-sealed part 2 of the spout or squeeze spout 3 of the bottle neck of the bag has a perforated hole 4 within the range that does not penetrate into the squeeze spout 3.
The spout 3 is provided so that the spout 3 can be used by tearing it off.

Further, the unsealed portion of the barrier laminate film 1 is opened and filled with a paste or liquid material, and after filling, heat sealing is performed to seal the material.

[Function] As described above, the present invention provides a barrier laminate film l.
After stacking the front and back two sheets and squeezing them into a bottleneck shape to form three peripheral edges and a spout or squeezing spout 3 and performing heat sealing 2 to form bag body A, the unsealed part of bag body A has become flat. The bag body A is opened, and a base-like or liquid substance is filled into the bag body A through this opening, and the bag body A is sealed by heat sealing. Furthermore, when it is desired to use the contents stored in the bag body A, the spout or aperture 3 is opened by tearing the perforation 4 provided on the spout 3 side of the spout or aperture 9, and the spout or aperture 3 is opened. The stored item is taken out from the aperture.

After use, the bottle neck can be folded back and held with clips to safely store stored items.

[Effects] As described above, in the present invention, when two aluminum foil barrier laminate films are superimposed and then heat-sealed on three sides except for one, at least the tip of one of them is tightened into a bolt neck shape. A paste-like paste that is heat-sealed and further has perforated holes for tearing in the vicinity of the neck portion within a range that does not directly contact the neck portion;
In a storage bag for liquids, overlap two sheets of aluminum foil barrier laminate film and heat seal on three sides, leaving one side open. At that time, leave a bottleneck-shaped spout at the tip of at least one direction, squeeze it, and heat it. It has been sealed,
In addition, there is a perforated hole near the neck, so when you want to use the contents filled in the bag, you can easily open the spout by tearing the perforated hole with your hand, allowing you to pour from the narrow spout. It can be poured without spilling to the outside, and since the bag is flat, it does not become swollen during transportation, carrying, or storage.
