It is a small sealed paper container that has excellent sealing properties and does not have a thick heat-sealed part.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used to package confectionery, medicines, 35mm photographic film, etc. that do not contain liquids. A small sealed paper container with excellent sealing properties and a thick heat-sealed part. This paper relates to improvements to sealed paper containers.

0002

[Conventional technology]

Traditionally, juice, milk, alcoholic beverages, etc. have been made using paper layers, resin film layers, and aluminum foil layers. Using laminated materials with layers etc., 4 body pieces and 4 sealing pieces are attached through the fold line. A box was made by heat-sealing a single blank with four fold-in pieces and an adhesive piece. Sealed paper containers for liquids are widely used.

0003 On the other hand, in the paper sealed container described above, the sealing piece, fold-in piece, and glue allowance piece overlap. The heat-sealed part where up to 5 layers of laminated material overlaps and becomes thick, making it difficult to heat-seal. Therefore, the sealing performance was likely to be incomplete. For this measure, for example, In Kaisho 59-150711, each of the folding pieces (13, 13, 13, 13) is The parts (13b, 13c) other than the obtuse-angled isosceles triangular parts (13a) and the glue allowance of the glue allowance piece (14) Remove the paper layer from the laminated material in parts (14b, 14c) other than part (14a) and heat seal the part. A paper sealed container for liquids that does not become thick has been disclosed.

[Problem that the idea aims to solve]

This invention can be used to package confectionery, medicines, 35mm photographic film, etc. that do not contain liquids. There was a request for a small sealed paper container, and this was not disclosed in the previous Japanese Utility Model Publication No. 59-150711. We devised a sealed paper container for liquids that prevents the heat-sealed part from becoming too thick. This is an improved version for non-liquid use. In other words, the conventional idea of Utility Model Application Publication No. 59-150711 In the plan, each paper layer of the folded pieces (13, 13, 13, 13) shown in Figure 4 may be removed. Because the isosceles triangular part (13a) has an obtuse angle, the density of the glue allowance piece (14) shown in Figure 4 is Since the paper layer of the seal part (14b) was removed, one blank was heat sealed and made into a box. Around the folded pieces (13, 13, 13, 13) shown in Figure 4 on the inner side of the sealed paper container, Laminated materials such as resin film layers and aluminum foil layers with paper layers removed may not be suitable for liquid applications. The problem is the occurrence of ``sag'', which is not a problem, and it is difficult to meet the requirements for high-speed filling and strength after making the box. There was a problem with that. Furthermore, the method disclosed in the conventional Japanese Utility Model Application Publication No. 59-150711 shown in Figure 4 is The folded part (14c) of the adhesive strip (14) is folded because the present invention is for non-liquid use. There was no need to fold back the folded portion (14c) to protect the cross section of the paper layer.

[0005]

[Means to solve the problem]

This invention uses a laminated material of a paper layer, a resin film layer, an aluminum foil layer, etc. As shown in Figure 1, the body piece (11,11,11,11) and the sealing piece (12,1) are connected through the fold line (20). 2, 12, 12), a folding piece (13, 13, 13, 13), and a glue piece (14) in one blank. In a sealed paper container made by heat-sealing the The parts ( 13b, 13c) other than the right-angled isosceles triangular parts ( 13a) or the folded pieces ( 13 ,13,13,13) The right angle parallel trapezoidal part (13c) on one side of the non-adhesive side of each of By removing the layer, the sealing performance is excellent and the heat-sealed part does not become thick. The present invention provides a small-sized sealed paper container.

[0006] Regarding the laminated material of this invention, such as a paper layer, a resin film layer, an aluminum foil layer, etc. , to suit the shape, size, and weight of the contents of small paper sealed containers. By selecting a paper layer such as coated cardboard, and by controlling the humidity, oxygen, and ultraviolet rays of the contents. For the purpose of preventing By selecting the Can be stacked without any problems. In this case, the outermost layer and the innermost layer of the laminated material of the present invention It is necessary to laminate a polyethylene film layer or the like that can be easily heat-sealed.

[0007] As shown in Figure 1, the body pieces (11,11,11,11) of the present invention are connected through the fold line (20). The sealing piece (12,12,12,12), the folding piece (13,13,13,13), and the adhesive piece (14) are arranged in series. Regarding the method of making a box by heat sealing a single blank, there is a conventional method of making a box made of paper for liquids. Similar to the sealed container, as shown in Fig. Heat seal the ends of (11) and the two sealing pieces (12,12) using the usual flame sealing method. After making a rectangular cylindrical paper container with openings on the left and right sides and storing the contents, open the left and right sides. The right isosceles triangular part (13a) is the body piece (11). Heat the left and right adhesive strips (14) by folding them perpendicularly to the The sealed sealing piece (12) and the two right-angled parallel trapezoidal parts (13b, 13c) and another sealing piece (12) with their respective fold lines (20) are brought together and this approach The sealed parts are then heat-sealed using a normal pressure sealing method to make a small sealed paper container. Rukoto can. In this case, two right-angled parallel trapezoidal parts (13b, 13c) or one straight By removing the paper layer of the rectangular parallel trapezoidal part (13c), it can be Improved conductivity improves heat-sealing sealability and reduces the thickness of the heat-sealed part. It's something you don't need.

[0008] The right-angled isosceles of each of the folded pieces (13,13,13,13) of the present invention as shown in Figure 1 Each of the parts ( 13b, 13c) other than the triangular part ( 13a) or the folded pieces ( 13, 13, 13, 13) How to remove the paper layer from the laminated material of the right angle parallel trapezoidal part (13c) on one side of each non-adhesive area , apply a pre-printed paper layer to a suitable coated cardboard or other paper layer with regular printing. The above part (13b, 13c or 13c) was punched (removed the paper layer) using a punching die, etc. Later, appropriate resin film layers, aluminum foil layers, etc. are laminated on both sides of this paper layer. By creating a fold line (20) and a cutting line (21) using a punching die in the normal punching process. So, the body piece (11,11,11,11), the sealing piece (12,12,12,12), and the folding piece (13,13,13,1) 3) and the adhesive piece (14) can be made in a row.

[0009] In this case, the paper sealed container is small and the heat-sealed part is not thick, so appearance is important. In this case, each of the folded pieces (13,13,13,13) other than the right-angled isosceles triangular part (13a) By removing the paper layer of the two right-angled parallel trapezoidal parts (13b, 13c), If the sealed container is relatively medium-sized and there are few problems such as sealing of the heat-sealed part, One right-angled parallel trapezoidal part ( 13 By removing the paper layer in c), the sealing performance is excellent and the heat-sealed part is thicker. This makes it possible to provide a small-sized paper sealed container that does not require much storage space.
