Description

Soft pack

Technical field

The invention relates to a soft package formed by folding a sheet and provided with at least one opening and closing mechanism in a first overlapping zone according to the preamble of claim 1. The invention further relates to a method for folding paper tissues. to wrap in a soft package.

Prior art

Soft packages for tissue paper such as tissues or paper facial wipes are very popular. Known soft packages are provided, for example, with a perforation on the front side to form an opening facilitator or tear-open flap. The soft pack can also be provided with a tape on the tear-open flap to close the soft pack after being torn open. The tape makes it easier to open the package.

Soft packages for wrapping handkerchiefs equipped with a retractable opening facilitator consisting of a tear-opening flap are described, for example, in US 5,796,113. The soft package is also provided with an adhesive label that covers the tear-open flap to improve the stability and convenience of the soft package.

The manufacture of a soft package provided with a perforation to form the opening facilitator is very reasonable cost. However, when closing the package after opening it by tearing, an interval in the package is covered only with a minimum of material and dirt may enter the package.

In order to prevent dirt from entering the package, the size of the interval can be very small. However, this may reduce the convenience with which the user removes a tissue from the soft pack.

US 6,318,625 B1 describes a soft paper tissue package provided with an opening and closing mechanism in a first overlapping zone, which is located on an upper side of the soft package. The opening and closing mechanism includes a sealing flap and an extension that are formed by grooves. Only the overlapping material in edge areas of the upper side is joined together by heat. The sealing flap is fixed to the extension by a pressure sensitive adhesive. In addition, a tape is provided to close the soft pack after opening it for the first time. Paper tissues left in the soft pack after first opening are well protected. However, the size of the interval is limited to the size of the side. In addition, paper tissues are caught at their small folded edges for removal from the soft pack.

Summary of the Invention

The object of the invention is to provide a soft paper tissue package in which the tissue is protected against dirt and that allows easy removal of paper tissues from the soft tissue. Another object of the present application is to provide a method of folding paper tissues for easy removal of a soft package.

These objects are achieved with a soft packet with the features of claim 1 and a method with the features of claim 10.

The basic idea of the invention is to provide an opening and closing mechanism including a sealing flap and an extension where the sealing flap overlaps the extension at least partially in a first overlapping zone, the sealing flap and the extension being formed by grooves located on opposite edges of a sheet that contact each other in the first overlapping zone, and an overlapping material and the first overlapping zone have been attached next to the sealing flap and extension, and where the opening mechanism and closure is placed on a larger surface of the soft package. The placement of the opening and closing mechanism on a larger surface of the soft package makes it possible to increase the interval. Since the sealing flap and the extension overlap one another at least partially covering the interval, dirt is prevented from entering the soft package after the first opening. For good protection, preferably the sealing flap completely overlaps the extension. Preferably paper tissues are folded and placed longitudinally

in the package so that their surfaces match the interval. This allows you to grab the tissue very easily to remove the soft pack. According to the invention, paper tissues, such as tissues, paper facial wipes, napkins or the like, are wrapped in the soft package. The soft pack is preferably formed by wrapping a sheet of film, paper or other packing material around the tissues. Overlapping areas on the side of the soft pack can protrude from the soft pack. However, preferably the overlapping areas on the sides fold and rest on the sides of the wrapped tissues. Preferably paper tissues are wrapped so that they are placed longitudinally in the soft package and their upper surfaces are generally parallel to the upper surface of the soft package.

In addition, the paper tissues in the soft package are folded at least one edge shorter than the width of the folded paper tissues and are aligned within the opening and closing mechanism. When the package is opened, the loose edge can be grasped very easily and access to paper tissues is further improved.

According to another characteristic of the invention, the sealing flap and / or the extension are formed by straight cuts or perforations. Fixed cuts or perforations can be produced at a very reasonable cost. The ends of the cuts may be provided with additional cuts to prevent breakage of the opening flap and / or extension.

According to another characteristic of the invention, the sealing flap and / or the extension are formed by inclined cuts or perforations. A perforation or inclined cut further improves the protection of paper tissues in the soft package.

According to an advantageous development of the soft package of the invention, the width of the sealing flap differs from the width of the extension. In particular, the position of the cuts or perforations does not coincide in the overlapping zone. This results in better protection of paper tissues. Preferably, the sealing flap is wider than the extension for greater convenience when opening and closing the soft pack.

According to another embodiment of the invention, the sealing flap and / or the extension are sealed or covered with an adhesive. Sealing or adhesive improves the protection of paper tissues in a soft package before opening it for the first time.

In another embodiment of the invention, the overlapping material in the first overlapping zone next to the sealing flap and the extension is welded together. Heat welding is a known process for joining overlapping areas of a soft package, in particular, if the soft package is made of film. If the soft package is made of paper or the like, the overlapping material in the first overlapping zone can be bonded, for example, with adhesive.

According to another feature of the invention, the opening and closing mechanism includes a tape. The tape improves the closure of the soft pack after opening it for the first time. Additionally, the tape simplifies the opening of the soft pack.

According to another embodiment of the invention, the soft package has a cuboid shape with a rectangular upper surface. Typically, the cuboid has three different lengths. However, embodiments that have two generally equal lengths are possible.

In another embodiment, the tissues are folded together so that the tissues can be folded in C, V or Z. In this embodiment, access to the tissues is further improved. The folding according to the invention can be carried out using conventional folding process technology, preferably using cross folding or longitudinal folding technology.

Another basic idea of the invention is to provide folded paper tissues with at least one edge shorter than the width of the folded paper handkerchief and wrap such paper tissues with a soft package that has an access range on the side, as has been described above, where the tissue can be grasped on the loose edge that matches the access interval.

Detailed description of preferred embodiments

Preferred embodiments of the invention will now be described in detail with reference to the drawings. The same elements will be designated with the same reference numbers in all drawings.

10 A schematic view of a soft package 1 is shown in Figure 1a. The soft package is formed in the form of a cuboid having an upper surface 10 and sides 12, 14. An opening and closing mechanism is provided on the upper surface 10 including a sealing fin 2 and an extension, which is not visible in Figure 1a since the sealing fin 2 completely overlaps the extension. Sealing fin 2 is formed by cuts

15 straight 20.

Figure 1b represents the soft package of Figure 1a, where the sealing flap 2 is open. Extension 3 is still closed, covering non-visible tissues wrapped in soft package 1.

20 The size of an access interval to the tissues depends on the length of the cuts 20. Since the access interval is placed on the upper surface 10 of the soft pack 1, the size of the access interval can be increased by comparison with an access range provided on the lateral surfaces 12, 14. Since the sealing flap 2 overlaps the extension 3, a good protection of paper tissues wrapped in the soft package is achieved.

Overlapping material 16 in the overlapping zone next to the sealing flap 2 is preferably joined by welding. The sealing flap and extension are not welded, but can be sealed or covered with an adhesive.

On the side 12 of the soft package 1, the ends of a folded sheet to form the soft package overlap and 30 contact paper tissues wrapped in the soft package 1. Instead of folding the ends of the sheet on the sides, the overlapping ends can be joined, for example by heat welding, and protruding from the sides

12.

Figure 2a schematically represents a sheet 4 to form a second embodiment of a soft pack 35 of the invention 1 '. The sheet 4 is provided with inclined cuts 22 to form a sealing fin 2 '. The sheet 4 is also provided with inclined cuts 32 to form a 3 'extension.

Figure 2b schematically represents a top view of the soft package 1 'formed by folding a sheet 4 of Figure 2a. As best seen in Figure 2b, the cuts 22 of the sealing fin 2 'do not match the 40 cuts 32 to form the extension 3'. As a result, the sealing fin 2 'overlaps the sides of the extension 3' and the protection of paper tissues wrapped in the soft package 1 'is improved.

The overlap zones 18 on the sides 12 'are not folded. In the illustrated embodiment, the overlapping zones 18 are joined by heat welding and protrude from the sides 12 '.

Figure 3 schematically represents a tissue 5 to be wrapped in a soft package of the invention. The paper handkerchief is folded so that the edges 50, 52 are shorter than the width W of the folded paper handkerchief 5. Preferably both edges 50, 52 are shorter, and the adjacent paper handkerchiefs 5 fold together.

When wrapped by a soft package of the invention, the loose edge 52 coincides with an access interval of the soft package. Therefore, the tissue 5 can be easily grasped on the loose edge 52.
