The present invention relates to containers for storing items such as razor cartridges.

Razor cartridges are usually sold in plastic distribution containers that contain a lot of shaving cartridges placed in the appropriate section of the container.

In the field related to the packaging of light snacks and condiments, know the use of a rectangular plastic container, the shape of which corresponds to an open box with a peripheral flange, closed with a plastic film glued around the flange, and the use of tear-off tab, which is formed by cutting in the longitudinal direction diagonally across one corner of the flange, with a triangular tongue remains attached to the sealing foil, with no visible gap between the triangular tongue and the adjacent part of the flange. Such packages, for example, used for light snacks, which were distributed in the U.S. under the brand name "PHILEAS FOGG". This known packaging are presented in figures 1, 2, labeled "prior art" (similar). The applicant believes that the plastic container 100 is formed of food grade thermoplastic material, and the flange 102 passes around the four sides (flange has the same width on opposite sides, but on the inside its width slightly different), the containers which R has the plastic covering film 104, which is sealed by the flange, and this film has a colored coating metal (apparently the vacuum method) its lower side, on its outer side has a printed product information, and a tear tab 106 remains glued to the film, when her tear. It is clear that when the plastic film is separated from the plastic container, but does not fully disconnect it, and then allow the film to return from the position shown in figure 2, back, blocking the hole in the container, then completely lost any ability to fully preserve prikrylova provisions film (MTPP), leaving the available opening of the container in accordance with the meaning of this term is discussed below. It is also known that plastic films possess the ability to resist the penetration of moisture and gases, protecting food products from quality loss.

It describes the known solutions also include bendable metal foil, which is used for closing plastic containers for portions of oil for pies or similar packaging for spices or canned products, which, for example, are supplied in the USA by the company KNOTTS BERRY FARM FOODS, INC. (PLACENTIA, CALIFORNIA). These containers also include a corner tear-off tab, which is formed by cutting in selling the flax direction of the flange part.

The concept of "multi-layer covering foil" means a thin metal foil, coated on the outside with plastic (with printed graphic data) and having a ground layer, bounding when heated. Plastic cover only acts as a barrier to moisture and gases. Foil with these containers can be purchased, but it must be made of metal, allowing permanent deformation of the container.

Figure 1-2 represent the known air-tight container for food products.

Figure 3-4 represents the handle, which is connected to a cartridge razor, placed in a sealed package to be opened.

Figure 5 is a multilayer structure removed the covering film, shown in figure 3.

6 is in the open position covering the th film for packaging, shown in figure 3 and are in the first stable state when the film opened.

7 is in the open position, the cover tape for packaging, as shown in figure 3 and are in the second stable state when the film opened.

As shown in figure 3 and 4, a hermetic package 10 is in the open position with the separated film. The package 10 includes a molded plastic container 12, the covering film 14 and the product for individual use. Mainly product for individual use is the cartridge 16 razor, placed in the storage area 18 within the container 12. This packaging can be used for products for individual use, such as a cartridge razor, disposable razor, toothbrush replaceable head toothbrush, a certain amount of silk thread, batteries, and similar consumable products that you can buy at the vending machine. The connecting end 110 of the handle 120 is shown in the position in which he promoted in the direction of the connecting structure 19 of the cartridge 16. The container 12 has a sealing surface 20 surrounding the entrance 22 to the storage area 18, and the cover film 14, is sealed relative to the sealing surface 20. The plastic tabs 24 (only one tab is shown in figure 3-4 and 6-7) attached to the lower Stour is not film 14 on two corners. The plastic tabs 24 comfortable at the beginning of the separation of the covering film 14.

In the manufacture of the container 12 is made of polypropylene by injection molding. Other materials that can be used for the manufacture of container 12 include polystyrene (partially crystallized polystyrene, vysokozharoprochnyh polystyrene or high impact polystyrene), polycarbonate, Acrylonitrile butadienestyrene, nylon, copolymer of styrene and Acrylonitrile. In the manufacture of the sealing sheet 118 (shown in figure 5 and discussed below), you can use not only the polypropylene, but other appropriate materials. After formation of the container 12, the cartridge 16 is placed in the container 12 in a predetermined connecting position, in which the connecting structure 19 is directed toward the entrance. Then, the foil 14 is hermetically fixed to the upper sealing surface 20 and the upper surfaces of the plastic reeds 24 by welding heat. You can also use to mount the film by radio frequency welding, ultrasonic welding or glue, is effective in the short-term pressure.

The film 14 may be made of printed information, including instructions on how to open and use the cartridge. The film 14 is made of a multilayer material, as shown in figure 5 (not to scale)Kosty material contains the upper layer 112, made from polyethylene terephthalate (print in reverse order), of 0.48 mil (0.012 mm, caliber 48); and 0.50 mil thick (0,013 mm, 50 caliber, also called "the 7.5 Ibs./ream") layer 114 polyethylene, preferably low density polyethylene), below (mostly white, opaque, but, alternatively, it may be transparent); 1,15 mil thickness (0.029 mm, 115 caliber) oriented layer 116 high density polyethylene, below, of 0.1 mil thick (approx) (also called approximately "2 Ibs./ream"), an adhesive layer polyetherurethane 117 below, as well as a 1.25 mil thickness (0.32 mm) co-extruded bottom sealing layer 118 low density polyethylene and ethylene vinyl acetate (28%), the bottom of which is made of ethylene vinyl acetate by heating associated with the container 12.

In the film 14, a layer of high density polyethylene and to a lesser extent layer of low density polyethylene have the ability to hold moisture, and to keep the MTPP film. Pet provides volume and transparency, as well as protecting the print data contained on its bottom surface. It also provides the structural integrity of the layered material, eliminating the gap and allowing you to retrieve the laminated material as a whole. The polyethylene terephthalate is chosen so that it is about eposteal mode of the accelerated testing, exposure to hot water at a temperature of 100° F (37,8° (C) in the bath for 24 hours without delamination. The layer of polyethylene (mainly low density polyethylene) acts as a tie coat between layers of high density polyethylene and polyethylene terephthalate. The polyethylene terephthalate chemically attractive for use with low density polyethylene to which warm (about 600° (F) (315,6°C)as a binder layer between the polyethylene terephthalate and high density polyethylene. The layer of polyethylene, preferably low density polyethylene) mostly opaque, in particular white, provides the background color for printing, and it provides opacity for aesthetically more uniform transition between places that are subjected to heat sealing, and places that are located farther away from the sealing surface. Polyetherurethanes layer 117, which is very thin, less than 1 mil (25,4 m), mostly amounting to only about 0.1 mil (2,54 m), acts as a binding layer for the connection layer 116 high density polyethylene and a sealing layer 118 low density polyethylene and ethylene vinyl acetate. The layer 118 of low density polyethylene and ethylene vinyl acetate, in particular, is designed to seal with polypropylene container 12. It is clear that the number atrevido the acetate in the sealing layer 118 can be changed depending on the material of the container 12. It is also clear that if you apply radio frequency or ultrasonic welding, it is possible to exclude the lower sealing layer 118. The thickness of the sealing layer 118 is not more of 1.25 mils or, otherwise, its weight may exceed the value at which the layer of high-density polyethylene has the ability to hold the cover in separated position.

The parameters that ensure the full preservation of prikrylova provisions film related to layered material, are provided with layers of low density polyethylene and high density polyethylene and, first of all, a layer of high density polyethylene. The parameters of the MTPP is such that when the film 14 is separated, the part remains attached to the container 12, and when the user then releases it, removing the hand, the film 14 remains bent or curved back after opening, as shown in figure 3-4 and 6-7, this provides easy access to contained in the container product. If there are products in the container, which must be retrieved by the hands of the user, the settings for the MTPP film, such that provided essentially unimpeded access of the finger to reach the product within the container. Basically, as shown in Fig.6, satisfactory results are obtained when the parameters that provide the SPP film, when the angle between the remote part of the film and the sealing surface 22 is greater than 30° and, more preferably, greater than 45° (as schematically shown by the dashed lines). On the other hand, as shown, for example, 6 or 7, satisfactory results for the parameters that provide the MTPP related to remote parts of the film that is left behind the position at which at least half of the area of the entrance to the container provides essentially unimpeded access to the inside of the object. Preferably, as shown in Fig.7, to a remote part of the film was mostly left behind the middle line passing through half of the container between its side surfaces. In particular, the film 14 remains bent back in such a way that the handle can be easily connected to the cartridge, and the cartridge to extract essentially unimpeded.

Properties, providing a barrier against moisture, is provided by layers of low density polyethylene and high density polyethylene, a first layer of high density polyethylene. Properties related to the barrier to moisture penetrating through the film, can be expressed in terms of characterizing the transmission rate of wet steam. Preferably, this rate was less than or equal to approx is Ino 0.16 g of water per 100 sq. inches (645,16 cm2) for 24 hours at a temperature of 100°F (37,8°C) and a relative humidity of 90%.

Use a layer of high density polyethylene together with a layer of low density polyethylene mainly provides a given combination of parameters that provide the MTPP film, and properties, which prevents the penetration of moisture.

Further, the film can be improved through the use of a layer of low density polyethylene, which is located between the outer layer of polyethylene terephthalate and a layer of high-density polyethylene, providing an additional advantage to protect the integrity of the film from the disruption and to ensure quality printing.

Film 14, made of plastic, has the advantage compared with the use of a metal foil, because it meets the requirements of the electronic control. In the electronic control small tag (inside of which is usually a metal) de-activated when payment is, therefore, not disabled the alarm, when paid by the buyer leaves the store. If the metal foil was used in a package containing a cartridge razor, the combination of metal foil and metal blades, located directly next to each other, can disrupt the regular functioning of the tags in the electronic control.

Other embodiments of the invention correspond to the formula. For example, metallized plastic layer, which in this embodiment may be formed by vapor deposition, can be used in small amounts without interfering with electronic control systems, while providing a specified attractive appearance of the container.
