Description

TECHNICAL FIELD The present invention relates to a packaging case for a packaging winding body in which a packaging resin sheet is wound around a winding core.

To prevent the food from drying or oxidizing, or to prevent the scent of the food from transferring to other foods, a wrap roll in which a thin wrap film for food packaging is wound on the core is used. The lap roll is generally stored in a dedicated storage box for use (see Patent Documents 1 and 2).
Although not shown, the storage box includes a main body box that rotatably stores a wrap roll of polyvinylidene chloride resin, and a lid that is swingably connected to the main body box and that opens and closes the opening of the main body box. It is configured. The main body box and the lid have a thickness of 0.2 mm or more and 1.3 mm or less and are formed by processing Kent paper having a smooth surface.

The main body box includes a bottom plate on which a lap roll is rotatably mounted, a front plate connected to the front part of the bottom plate, a rear plate connected to the rear part of the bottom plate and facing the front plate, both side parts of the bottom plate, and a front plate. It is formed into an elongated box whose upper part is opened from both side portions of the face plate and a pair of side face plates which respectively close openings defined by both side portions of the rear face plate.

On the other hand, the lid includes an upper lid plate that is swingably connected to an upper portion of the rear plate, a front lid plate that is connected to a front portion of the upper lid plate and overlaps an upper portion of the front plate of the storage box, and the lid. It is composed of a substantially V-shaped cutting blade that is attached to the front plate and cuts the wrap film of the wrap roll, and a pair of lid side plates that are connected to both sides of the lid front plate and overlap the upper side plates of the storage box. , Open and close the upper opening of the main body box.

In the above configuration, in order to prevent the food from drying or oxidizing, first, grasp the main body box of the storage box and open the lid, and pull out a thin transparent wrap film from the wrap roll in the storage box for the required length. The drawn wrap film covers and packages food. When the food is packaged in this way, the lid of the storage box is completely closed, and the cutting blade of the lid cuts the drawn wrap film to prevent the food from drying and oxidizing.

WO2018/163592 JP, 2005-247403, A

The conventional storage box is configured as described above, and the main body box and its front plate are merely formed by processing Kent paper, and the surface is smooth, so the wrap film pulled out by the cutting blade of the lid is cut. Then, the remaining short wrap film may slip and rewind to the wrap roll side without sticking to the front plate of the main body box.

When the remaining short wrap film is rewound on the wrap roll side, it is necessary to open the lid of the storage box and pull the wrap film again from the wrap roll. However, since it is not easy to visually grasp the end of the transparent thin wrap film, it takes a lot of time to pull out the work, and there is a problem that the work cannot be speeded up. This problem is very serious in restaurants, hotels, inns, etc. where a large amount of wide wrap film is used and reliable food packaging is required in a short time, and an urgent solution is desired.

As a method of solving such a problem, there is a method of applying an adhesive varnish to the front plate of the main body box to attach a wrap film to the front plate of the main body box to prevent rewinding. However, when this method is adopted, when the thin wrap film attached to the front plate of the main body box is pulled up and peeled off, a big problem that the thin wrap film is easily broken occurs newly.

The present invention has been made in view of the above, and prevents the polyvinyl chloride resin sheet from being rewound on the packaging roll, without damaging the polyvinyl chloride resin sheet attached to the front plate of the cosmetic box. An object of the present invention is to provide a peelable packaging roll cosmetic box.

The protruding peak height Spk indicating the surface roughness of the surface of the cosmetic case 1 is 0.58 μm or more and 1.27 μm or less, preferably 0.63 μm or more and 1.22 μm or less, and more preferably 0.68 μm or more. 1.17 μm or less is preferable.

As shown in FIG. 2 and FIG. 4, the packaging winding body 20 includes a winding core 21 shorter than the bottom plate 2 of the cosmetic case 1, and a transparent strip-shaped polyvinyl chloride resin film on the outer peripheral surface of the winding core 21. 22 is wound around 20 m to 50 m, or around 50 m to 110 m, and is housed in the cosmetic case 1 so as to be freely rotatable. The winding core 21 is formed in a cylindrical shape from a predetermined paper. The polyvinyl chloride resin film 22 is formed into a flexible thin film with a polyvinyl chloride (PVC) resin having excellent heat resistance, water resistance, adhesiveness, a softening agent, a stabilizer, etc. Is pulled out by a predetermined length across the upper end, which is the free end of the front plate 3 of the cosmetic case 1, and then cut by the cutting teeth 30 of the cosmetic case 1 to be used for packaging food.

The adhesive force between the wound polyvinyl chloride resin films 22 of the wrapped package 20 depends on the leaving period of the wrapped package 20 around which the polyvinyl chloride resin film 22 is wound, and the like. 82N or more and 1.60N or less, preferably 0.87N or more and 1.55N or less, and more preferably 0.92N or more and 1.50N or less.

As shown in FIGS. 5 to 7, the cutting tooth 30 is formed of, for example, a metal or a biodegradable resin into an elongated rectangular thin plate, and a plurality of saw teeth 31 are continuous in at least one side of the both sides in the longitudinal direction. In addition, the saw teeth 31 are formed in a small triangle, and the polyvinyl chloride resin film 22 pulled out from the packaging roll 20 can be quickly cut. The front surface of the bottom plate 2 is joined by caulking, and in the case of a biodegradable resin, it is bonded to the front surface of the bottom plate 2.

When the material of the cutting tooth 30 is a biodegradable resin, examples of the biodegradable resin include biopolyester, bacterial cellulose, and fatty acid polyester. As a specific material for the cutting tooth 30, for example, Ecologue (registered trademark) manufactured by Mitsubishi Chemical Co., Terramac [product name] manufactured by Unitika Co., Ltd., Bioclear [product name] manufactured by Asahi Kasei Co., Ltd., etc. are preferably used. To be done.

One side of the cutting tooth 30 is located in the vicinity of the connecting portion between the front surface of the bottom plate 2 and the front plate 3, in other words, in the vicinity of the boundary fold line, and the plurality of saw teeth 31 are slightly located from the front surface of the bottom plate 2. The plurality of saw teeth 31 slightly protruding to the outside serve to cut the polyvinyl chloride resin film 22 pulled out from the packaging winding body 20. Since the cutting teeth 30 are joined to the front surface portion of the bottom plate 2 instead of the overlapping body plate 8, the polyvinyl chloride resin film 22 is pulled out of the packaging roll 20 longer than in the conventional example during cutting. , Faces a region extending from the upper part to the lower part of the surface of the front plate 3.

In the above configuration, when assembling and manufacturing/shipping the packaging box 1 for the packaging roll 20, the unfinished packaging box 1 set by folding it flat in the box making machine is first raised to a hollow corner. The package winding body 20 that is formed into a tubular shape and is already manufactured is horizontally inserted from one side portion of both open side portions.

In the cosmetic case 1 into which the packaging roll 20 is inserted, a pair of inner flaps 4A.4A, 4A. Are sequentially folded (see FIG. 5), and the side plate 15 is folded on the surface of the inner flap 4 that is folded later, and the tongue flap 16 is placed between the pair of inner flaps 4A and the ceiling cover plate 7. The both sides which are sandwiched and adhered to each other by the inner flap 4 and the side plate 15 are closed.

At this time, when the length of the pair of inner flaps 4 and 4A on each side of the cosmetic case 1 is different, the long inner flap 4A is folded first, and the short inner flap 4 is placed on the surface of the long inner flap 4A. You can fold it and stack it. By doing so, the postures of the pair of inner flaps 4 and 4A can be stabilized, so that the hot melt adhesive can be appropriately applied to the surfaces of the pair of inner flaps 4 and 4A, and the back surface of the side plate 15 can be firmly fixed. Can be glued.

When applying the hot melt adhesive, the hot melt adhesive can be divided into a plurality of pieces along the plurality of perforations 5 of the inner flaps 4 and 4A and beet applied. This makes it possible to stabilize the application range, application position, and application amount of the hot melt adhesive, even if it is difficult for the polyolefin-based hot melt adhesive to adhere, and ensure reliable adhesion.

When both open sides of the cosmetic case 1 are closed, ultraviolet light is irradiated to both sides of the cosmetic case 1 and its vicinity, respectively, from the ultraviolet light irradiating device, and specifically, near each side of the cosmetic case 1, specifically, The folded side plate 15 and its vicinity are inspected by the inspection device. As a result of the inspection, if there is no problem in appearance on both sides of the cosmetic case 1, the cosmetic case 1 is regarded as a good product, and the cosmetic case 1 can be shipped together with other good cosmetic containers 1 in cardboard boxes.

Next, when the makeup for the packaging roll 20 is purchased and put in a usable state, the peeling piece 11 is torn off along the perforations 10 from the stacking body plate 8 of the makeup box 1 and removed. The body piece 9 of the stack body plate 8 can swing, and the ceiling cover plate 7 that covers and protects the package winding body 20 can be opened. If the ceiling cover plate 7 can be opened, the packaging roll 20 stored in the cosmetic case 1 can be freely handled, so that the polyvinyl chloride resin film 22 of the packaging roll 20 can be used. It can be in a state.

Next, when pulling out the polyvinyl chloride resin film 22 from the cosmetic case 1 to prevent the food from being dried or oxidized, first, the vicinity of the central portion of the cosmetic case 1 is grasped and the cutting teeth 30 of the bottom plate 2 are raised. (See FIGS. 6 and 7), the ceiling cover plate 7 of the cosmetic case 1 is opened, and the transparent thin polyvinyl chloride resin film 22 is pulled out from the packaging roll 20 by the required length. After closing the ceiling cover plate 7, the thin polyvinyl chloride resin film 22 pulled out while inclining the cosmetic case 1 to the outside covers and wraps the food.

At this time, the coefficient of kinetic friction when the polyvinyl chloride resin film 22 of the packaging roll 20 is pulled out while slidingly contacting the upper end of the front plate 3 of the cosmetic case 1, is 0.248 or more and 0.667 or less, preferably The optimum value is 0.253 or more and 0.662 or less, more preferably 0.258 or more and 0.657 or less. This is because if the dynamic friction coefficient is 0.248 or more and 0.667 or less, the polyvinyl chloride resin film 22 can be easily pulled out from the package winding body 20.

The coefficient of static friction when the polyvinyl chloride resin film 22 of the packaging roll 20 is pulled out while sliding on the upper end of the front plate 3 of the cosmetic case 1 is 0.256 or more and 0.319 or less, preferably 0. The optimum value is 0.261 or more and 0.314 or less, more preferably 0.266 or more and 0.309 or less. This is also because if the coefficient of static friction is 0.256 or more and 0.319 or less, the polyvinyl chloride resin film 22 can be smoothly pulled out from the package winding body 20.

After the food is coated and packaged with the polyvinyl chloride resin film 22, the polyvinyl chloride resin film 22 is pressed against the cutting teeth 30 of the bottom plate 2 to cut the food, so that the food can be prevented from being dried or oxidized. At this time, when the polyvinyl chloride resin film 22 is cut by the cutting teeth 30 of the cosmetic case 1, the remaining long polyvinyl chloride resin film 22 is different from the conventional example in that the surface of the front plate 3 of the cosmetic box 1 is different. To the package winding body 20 side due to the decrease in slipperiness.

According to the above configuration, the surface roughness of the front plate 3 is determined in consideration of the combination of the decorative case 1 made of coated cardboard and the polyvinyl chloride resin film 22 and the characteristics of gravure printing or offset printing on the surface of the decorative case 1. Since the numerical value is limited, the polyvinyl chloride resin film 22 adheres and adheres to the surface of the front plate 3 of the cosmetic case 1. Due to this adhesion, the polyvinyl chloride resin film 22 can be prevented from being rewound on the package winding body 20, and the labor of pulling out the polyvinyl chloride resin film 22 can be saved. Therefore, the end portion of the transparent thin wrap film can be easily grasped, the work of pulling out the polyvinyl chloride resin film 22 can be simplified, and the work can be speeded up.

Further, in restaurants, hotels, inns, etc. where a large amount of wide wrap film is used and reliable food packaging is required in a short time, the pulling out work of the polyvinyl chloride resin film 22 can be expected greatly. In addition, since it is not necessary to apply an adhesive varnish to the front plate 3 of the cosmetic case 1, when removing the thin polyvinyl chloride resin film 22 attached to the front plate 3 of the cosmetic case 1, thin polyvinyl chloride is used. It is possible to eliminate the possibility that the resin film 22 is easily broken.

Further, instead of adhering the cutting teeth 30 to the laminated body plate 8, the cutting teeth 30 are joined to the bottom plate 2 and the polyvinyl chloride resin film 22 is cut by the cutting teeth 30, so that the dressing box 1 has a normal shape. An increase in the facing area between the face plate 3 and the polyvinyl chloride resin film 22 can be expected. Therefore, the polyvinyl chloride resin film 22 can be pulled out and adhered to the polyvinyl chloride resin film 22 longer than before, and the rewinding of the polyvinyl chloride resin film 22 can be effectively prevented.

Further, since the cutting teeth 30 are joined to the bottom plate 2 of the cosmetic case 1, even if the decorative case 1 is strongly gripped, it is possible to prevent the ceiling cover plate 7 from being bent and deformed. Therefore, it is possible to effectively prevent the cutting of the polyvinyl chloride resin film 22 from being hindered. Further, when the cutting teeth 30 are made of biodegradable resin instead of metal, the safety is improved, the sharpness is not significantly changed, and the sorting and disposal at the time of disposal are easy. Further, after the design is gravure-printed or offset-printed on the surface of the cosmetic case 1, there is no need to apply an adhesive varnish to at least the surface of the front plate 3 of the cosmetic case 1, so that the cosmetic case 1 is inexpensive. In addition, it can contribute to rapid manufacturing.

In the above embodiment, the arithmetic mean roughness Ra of the entire surface of the cosmetic case 1 is 0.48 μm or more and 1.29 μm or less, the maximum height Rz is 0.06 μm or more and 0.33 μm or less, and the protruding peak height Spk is Although 0.58 μm or more and 1.27 μm or less, the arithmetic mean roughness Ra of only the front plate 3 surface of the cosmetic case 1 is 0.48 μm or more and 1.29 μm or less, and the maximum height Rz is 0.06 μm or more and 0.33 μm or less. Further, the height Spk of the protruding peak portion may be set to 0.58 μm or more and 1.27 μm or less.

In addition, the inner flaps 4 and 4A of the cosmetic case 1 in the above-described embodiment may be formed with projecting rewind preventing portions that are respectively fitted to both open ends of the winding core 21 of the packaging winding body 20. Further, a plurality of adhesive portions 12 may be formed side by side at a predetermined interval in the back surface longitudinal direction of the peeling piece 11, but a plurality of adhesive portions 12 may be formed side by side at a predetermined interval on the front surface of the front plate 3. Is also good. Further, notches 14 that partially extend along the peripheral edges of all the adhesive portions 12 may be formed at a predetermined interval in at least the surface longitudinal direction of the peeling piece 11. Further, although the cutting teeth 30 are mainly elongated rectangles, they can be formed into a thin plate such as an elongated substantially V-shape if necessary.

Hereinafter, an example of the packaging case for a packaging roll according to the present invention will be described together with a comparative example.
[Example 1]
First, a decorative case for Polymer Wrap (registered trademark) [Shin-Etsu Polymer Co., Ltd.: product name] shown in FIG. The surface roughness of the front plate surface, specifically, the arithmetic average roughness Ra, the maximum height Rz, the arithmetic average roughness Sa, and the protruding peak height Spk were measured, and the measurement results are shown in Table 1. ..

The coated cardboard was CRC 500 g/m ² [manufactured by Rengo Co., Ltd.: product name], and the punching dimensions were 235 mm×439 mm. Further, the surface roughness of the front plate surface was measured by a non-contact method using a high precision laser microscope [manufactured by Olympus Corporation: product name LEXT OLS-4000]. This laser microscope is a 3D measuring laser microscope that irradiates the surface laser light on the front plate of a cosmetic box, which is a measurement object, and captures the brightness of reflected light as height information.

After measuring the surface roughness of the front plate surface of the cosmetic box, measure the dynamic friction coefficient and static friction coefficient when the polyvinyl chloride resin film of the packaging roll is pulled out while sliding on the upper end of the front plate of the cosmetic box. The measurement results are shown in Table 1.

The packaging winding body was Polymer Wrap (registered trademark) [manufactured by Shin-Etsu Polymer Co., Ltd.: product name] in which a transparent band-shaped polyvinyl chloride resin film was wound around the outer peripheral surface of the winding core by 45 m. The adhesive force between the wound polyvinyl chloride resin films of this packaging wound body was 1.50 N when measured. As for the adhesive force, a polyvinyl chloride resin film is formed in a size of 25 cm ² , and the polyvinyl chloride resin film is pressed with a compressive stress of 300 g (2.94 N) for 60 seconds and then peeled at a speed of 100 mm/min. The test for measuring the maximum load point was performed and measured.

As a specific method for measuring the adhesive force, first, a pair of cylindrical bodies were prepared, and a polyvinyl chloride resin film was attached to the bottom surface of each cylindrical body so as not to loosen and firmly fixed with a band. Here, the columnar body has a weight of 300 g and a bottom surface area of 25 cm ² . For the measurement, it was decided to use the same polyvinyl chloride resin film as the measurement of the dynamic friction coefficient.

After firmly fixing the polyvinyl chloride resin film, place the other cylinder on one cylinder so that the surfaces of the polyvinyl chloride resin film overlap each other, and the lower cylinder is loaded with 300 g of the weight of the upper cylinder. In this state, the cylindrical body on the upper side was left for 1 minute, and the upper cylinder was pulled up at a speed of 100 mm/min to measure the force required for peeling the polyvinyl chloride resin films from each other. The temperature of the measurement environment during this measurement was 25°C.

When measuring the friction coefficient of a polyvinyl chloride resin film, a surface property measuring instrument [manufactured by Shinto Kagaku Co., Ltd.: product name: Tribogear TYPE14] is used in accordance with the JIS K 7125 (ISO8295) standard. The dynamic friction coefficient and the static friction coefficient when the vinyl chloride resin film was slid were measured. In this measurement, when the polyvinyl chloride resin film having a width of 30 cm is pulled out from the package roll, the area where the upper end of the cosmetic case and the polyvinyl chloride resin film are in sliding contact is 30 cm×0.03 cm≈1 cm ² . The initial pulling force of the polyvinyl chloride resin film is about 200 g.

As a specific method of measuring the coefficient of friction, first, set the front plate of a cosmetic box cut out to a size of 4 cm x 10 cm on the moving table of the surface texture measuring machine and set the surface on which the design was gravure printed upwards. A 1 cm×4 cm thinly cut polyvinyl chloride resin film was set in a separate indenter of the surface texture measuring machine. The area measured by the indenter is 1 cm×1 cm square.

After setting the polyvinyl chloride resin film on the indenter in this way, attach the indenter to the surface property measuring machine, bring the polyvinyl chloride resin film of the indenter into contact with the front plate on the moving table, and put 200 g on the weight pan of the surface property measuring machine. After placing the weight of No. 3 for 10 seconds and standing still, the moving table was moved horizontally at 70 mm for 70 mm to measure the dynamic friction coefficient and the static friction coefficient.
