Description

The present invention relates to a skin pack package in which articles are packed with a film.

A skin pack package including a mount, an article placed on the mount, and a film attached to the upper surface of the mount while covering the article is known (for example, Patent Document 1 (FIGS. 1 to 4). )reference).

Patent Document 1 will be described with reference to the following figure.
7A and 7B are views for explaining the basic structure of the conventional technique, in which FIG. 7A is a perspective view of a conventional skin pack package, FIG. 7B is a rear view thereof, and FIG. 7C is a line cc of FIG. 7A. The cross-sectional view, (d) is an enlarged view of part d of (c).

As shown in FIG. 7A, the skin pack package 100 includes a mount 101, an article 102, and a film 103.
As shown in FIG. 7B, the mount 101 is provided with an elongated hole 104 extending along one side of the article 102.

As shown in FIG. 7 (d), which is an enlarged view of part d of FIG. 7 (c), when the heated and softened film 103 is evacuated downward, a part of the film 103 enters the elongated hole 104. The cross section becomes U-shaped. The tip of the U-shaped portion 105 becomes a fragile portion.

In FIG. 7A, when the article 102 is raised according to the arrow 106, the tip of the U-shaped portion 105 breaks, so that the film 103 can be peeled off from the mount 101 and the article 102 can be taken out.

However, since the U-shaped portion 105 shown in FIG. 7D is not formed by a mold, the finished form is determined by what is called a process. Due to fluctuation factors such as fluctuations in heating temperature and variations in the thickness of the film 103, the shape of the U-shaped portion 105 varies, and the tip of the U-shaped portion 105 may not be broken with a certain probability.

When the film cannot be broken, the worker tries to cut the film 103 with the cutter knife 107 as shown in FIG. 7 (c). At this time, the article 102 may be scratched by the cutter knife 107.

Further, in FIG. 7A, since the film 103 has no fragile portion on the two sides 108 and 109 orthogonal to the elongated hole 104, a relatively large force is required to break the film 103 at this portion. ..
A weak worker tries to cut the lower edges of the two sides 108 and 109 with a utility knife 107. At this time, the article 102 may be scratched by the cutter knife 107.

When the use of the cutter knife 107 is prohibited, damage to the article 102 can be avoided, but the article 102 cannot be taken out quickly because it takes time to break the film 103. As a result, productivity is reduced. A decrease in productivity is not desirable.
Therefore, it is expected that the productivity will be improved after allowing the use of the cutter knife 107.

JP-A-2017-65728

An object of the present invention is to provide a skin pack package capable of facilitating peeling of a film and quickly and easily taking out an article on the premise of using a cutter knife.

The invention according to claim 1 is a skin pack package including a mount, an article placed on the mount, and a film attached to the upper surface of the mount while covering the article.
The mount has fine serrations on at least one of the four sides.
A cut recommended line connecting the side having the saw tooth portion and the side parallel to this side is written on the upper surface of the mount at a portion away from the article, and the cut recommended line and the side having the saw tooth portion are formed. A recommended peeling line extending from the intersection of the above to the article is marked.
The film is characterized in that pseudo perforations formed by the sawtooth portions are formed on the film.

The invention according to claim 2 is the skin pack package according to claim 1.
The film is characterized by having overhanging portions protruding from each of the four sides of the mount.

The invention according to claim 3 is the skin pack package according to claim 1 or 2.
The mount is a double-sided corrugated cardboard in which an upper liner is attached on the corrugated paper and a lower liner is attached under the corrugated paper, or a single-sided corrugated cardboard in which an upper liner is attached on the corrugated paper. ,
It is characterized in that at least the sawtooth portion is formed on the upper liner.

The invention according to claim 4 is the skin pack package according to any one of claims 1 to 3.
The mount is characterized in that it is provided with a plurality of ventilation holes penetrating vertically.

In the invention according to claim 1, the skin pack package is provided with a recommended cut line and a recommended peeling line. In addition, the film has pseudo perforations due to the serrations on the mount.

The worker cuts the film with a utility knife along the recommended notch line. Next, pull the film according to the recommended peeling line. The film breaks at the pseudo-perforated part. The film is peeled off from the mount by the pseudo perforation and the cutting line by the cutter knife, and the article is easily taken out.

Since the recommended notch line is marked on the part away from the article, there is no need to worry about the article being damaged by the cutter knife.
Therefore, according to the present invention, on the premise of using a cutter knife, a skin pack package that facilitates peeling of a film and can quickly and easily take out an article is provided.

In the invention according to claim 2, the film has an overhanging portion that projects from each of the four sides of the mount.
The overhanging portion includes a narrow overhanging portion that overhangs several millimeters from the mount and a wide overhanging portion that overhangs several tens of millimeters from the mount.

Temporarily, after placing the article on the mount, evacuating the film, and attaching it to the mount, trimming the narrow overhang and / or wide overhang from the mount is cut along the sides of the mount with a utility knife. When this is carried out, the appearance of the skin pack package is improved.
However, when cutting the film, there is a concern that the article may be damaged and the trimming man-hours increase.

In this regard, in claim 2, the overhanging portion is left in the skin pack package. Since the narrow overhang and / or the wide overhang is not cut off, trimming is not required, no trimming man-hours are required, and there is no concern that the article will be damaged.

In the invention according to claim 3, the mount is corrugated cardboard.
Corrugated cardboard has a high cushioning property and exerts an effect of protecting articles well. On top of that, since general-purpose corrugated cardboard can be used, the skin pack package can be manufactured at low cost.

In the invention according to claim 4, the mount is provided with a plurality of ventilation holes.
It is possible to evacuate and attach the film to the mount without providing ventilation holes. However, it takes a long time to attach the film to the mount in a predetermined form.
In this regard, in claim 4, since the mount is provided with the ventilation holes, the work time until the film is attached to the mount in a predetermined form is significantly shortened, and the productivity is improved.

It is an exploded view of the skin pack package body which concerns on this invention. It is a structural drawing of double-sided corrugated cardboard as a mount. It is a figure explaining the skin pack method. It is a figure explaining the operation of the saw tooth part. It is a figure explaining the procedure of unpacking a skin pack packing body. It is a figure explaining the skin pack packing body of various forms. It is a figure explaining the basic structure of the prior art.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the skin pack packing body 10 includes a mount 20, an article 40 mounted on the mount 20, and a film 50 that covers the article 40 and adheres to the upper surface 21 of the mount 20.
In principle, the component of the mount 20 is paper (including recycled paper), but it may be a resin plate that resembles paper, and is not limited to paper in a narrow sense.

A heat-sensitive adhesive is applied to the surface of the film 50 on the side of the mount 20. The heat-sensitive adhesive softens at a predetermined temperature (for example, 120 ° C.) and hardens when cooled to exhibit adhesiveness.
Of the four sides 22, 23, 24, 25, the mount 20 has fine sawtooth portions 26 on the two sides 22, 24 in this example. The shape of the sawtooth portion 26 will be described in detail with reference to FIG.

Then, on the upper surface 21 of the mount 20, a cut recommended line 27 connecting the side 22 having the sawtooth portion 26 and the side 24 parallel to this side 22 is written by printing or the like.
Further, on the upper surface 21 of the mount 20, the intersection of the recommended cut line 27 and the side 22 having the sawtooth portion 26 is set as the starting point 28, and the article 40 (as shown in FIG. 4A) is placed at a predetermined position on the mount 20. The peeling recommended line 29 extending toward the article 40) is marked by printing or the like.

The recommended lines 27 and 29 are preferably arrows, but may be simple lines. Alternatively, it may be a line in which black Δ and white Δ are continuous.
In addition to printing, such recommended lines 27 and 29 may be attached with stickers, stamped, written with a brush, or painted. In short, if the lines can be visually confirmed by the worker, the shape and marking method of the lines may be used. Is not particularly limited.

Preferably, the circled number 1 is marked along the cut recommended line 27, and the circled number 2 is marked along the peeling recommended line 29. The work procedure is clarified by the circled numbers 1 and 2.
Further, the mount 20 is provided with a plurality of ventilation holes 31 penetrating in the front and back directions of the drawing.

The mount 20 may be a so-called paperboard, but is preferably corrugated cardboard.
As corrugated cardboard, double-sided corrugated paper and single-sided corrugated paper are widely used in practical use. The structure of the double-sided corrugated cardboard will be described with reference to FIG.

As shown in FIG. 2A, the double-sided corrugated cardboard as the mount 20 is attached under the corrugated paper 32 as the core material, the upper liner 33 attached on the corrugated paper 32, and the corrugated paper 32. It consists of a lower liner 34.
The single-sided corrugated cardboard is composed of a corrugated paper 32 and an upper liner 33 attached on the corrugated paper 32.

As shown in FIG. 2 (b), which is an enlarged view of the b portion of FIG. 2 (a), a saw tooth portion 26 is formed on the side 22 of the upper liner 33. In the saw tooth portion 26, peaks 26a and valleys 26b are alternately continuous. The top of the mountain 26a is rounded. Therefore, even if the worker hangs his / her finger, the finger does not hurt.

Since the sawtooth portion 26 is easily formed by pressing the roller mold with the sawtooth against the side 22, the cost of forming the sawtooth portion 26 is small.
The sawtooth portion 26 is preferably provided on the upper liner 33 and the lower liner 34. However, although it is essential for the side 22 of the upper liner 33, it is optional whether or not it is provided on the lower liner 34.

Next, the skin pack method will be described with reference to FIG.
As shown in FIG. 3A, the skin pack device 60 is provided in, for example, a table 62 having a plurality of vacuum holes 61 penetrating vertically, a vacuum duct 63 covering the lower surface of the table 62, and the vacuum duct 63. It includes a connected vacuum pump 64 and a heater 65 located above the table 62. The vacuum pump 64 may be an exhaust blower, and may be any device that can reduce the pressure inside the vacuum duct 63 to atmospheric pressure or less.

The worker 66 puts the mount 20 on the table 62. The article 40 is placed at a predetermined position on the mount 20. In parallel, the heater 65 heats the film 50 to a predetermined temperature. The film 50 is preferably a wound film wound around a core.
The vacuum pump 64 starts evacuation by operating the button of the worker 66. In parallel, the heated film 50 is lowered.

As shown in FIG. 3B, the air between the film 50 and the mount 20 is discharged by the vacuum pump 64. As a result, the film 50 is attached to the upper surface of the mount 20 while surrounding the article 40.
The operation of the sawtooth portion 26 at this time will be described with reference to FIG.

As shown in FIG. 4A, the film 50 projects from the four sides 22, 23, 24, and 25 of the mount 20, and the projecting portion 51 is also evacuated.
Then, as shown in FIG. 4B, which is an enlarged perspective view of the portion b of FIG. 4A, the film 50 is pressed against the sawtooth portion 26, particularly the mountain 26a.

As shown in FIG. 4 (c), which is a cross-sectional view taken along the line cc of FIG. 4 (b), dents 52 are intermittently formed in the film 50 which has been heated and softened. The dents 52 are lined up in a straight line and are visible as a pseudo sewing machine. Hereinafter, the pseudo perforation will be referred to as a pseudo perforation (FIG. 5A, reference numeral 53).

In FIG. 4A, after the film 50 is attached to the mount 20, the worker 66 separates the film 50 from the rolled film by running a cutter knife along the cutting line 55 along the side 24.
The cutting line 55 shown by the imaginary line is separated from the mount 20 by a distance t (this t is several millimeters) so as not to damage the mount 20.

The worker 66 side from the cutting line 55 becomes the obtained skin pack packing body 10. The skin pack packing body 10 has an overhanging portion 51 that projects from the four sides 22, 23, 24, and 25 of the mount 20.
Of the four overhanging portions 51, the overhanging portion 51 on the cutting line 55 side is a narrow overhanging portion 51a having an overhanging allowance t of several millimeters, and the remaining three overhanging portions 51 are wide overhanging portions 51b having an overhanging allowance T of several tens of millimeters. It becomes.

The procedure for unpacking the obtained skin pack packing body 10 will be described with reference to FIG.
As shown in FIG. 5A, the film 50 is cut with a cutter knife 54 along the recommended cutting line 27. The cutting line stops at the pseudo perforation 53.
That is, the length of the recommended cut line 27 matches the width of the mount 20. Since the soft film 50 is mounted on the sturdy mount 20, the film 50 is easy to cut.

If it is attempted to cut the wide overhanging portion 51b, it is difficult to cut because the film 50 is soft. It is necessary to insert an appropriate stand, which is troublesome. In the present invention, this is not necessary.

As shown in FIG. 5B, when the film 50 is hung with a finger 56 according to the recommended peeling line 29 and pulled, the film 50 is easily cut along the pseudo perforation 53.
It should be noted that at least one pseudo perforation 53 is sufficient, but there may be a plurality of pseudo perforations 53.

Next, a skin pack packaging body 10 having a form different from that of the skin pack packaging body 10 described with reference to FIG. 4A will be described with reference to FIG.
As shown in FIG. 6A, the skin pack packing body 10 may have a wide overhanging portion 51b protruding from each of the four sides 22, 23, 24, and 25 of the mount 20.

FIG. 6B is a comparative example, and in the skin pack packing body 110 having no pseudo perforation 53, it is necessary to cut the entire width of the film 112 along the cutting line 111. It is not easy to cut the wide overhanging portion 112b. In the case of FIG. 6A, there is no need to worry about it.

Next, an example in which a cutting step is further applied to the skin pack package 10 described with reference to FIG. 4 (a) is shown in FIG. 6 (c).
As shown in FIG. 6 (c), the wide overhanging portion 51b is excised.
The obtained skin pack packing body 10 has narrow overhanging portions 51a protruding from the four sides 22, 23, 24, and 25 of the mount 20.

FIG. 6D is a comparative example, in which the wide overhanging portion 112b and the narrow overhanging portion 112a are cut so that the film 112 has the same size as the mount 113 without leaving the narrow overhanging portion 51a. When the cutter knife (FIG. 5, reference numeral 54) is run by the worker's hand, the cutter knife meanders to some extent. As a result, dents 115, 116 and the like are formed on the skin pack packing body 110, and the product quality is deteriorated. In the case of FIG. 6 (c), there is no need to worry about it.

Further, although the appearance of the skin pack package 10 shown in FIG. 6A is slightly deteriorated, the skin pack man-hours can be reduced because the trimming step of cutting off the wide overhanging portion 51b is unnecessary. The same applies to the skin pack packing body 10 shown in FIG. 4 (a).

On the other hand, the skin pack package 10 shown in FIG. 6C requires a trimming step of cutting off the wide overhanging portion 51b, but the appearance is improved.
Therefore, whether the final appearance of the skin pack package 10 is FIG. 6 (a), FIG. 6 (c), or FIG. 4 (a) may be appropriately selected according to the request. ..

Next, the operation of the ventilation holes 31 provided in the mount 20 of FIG. 1 will be described.
A skin pack is possible even if the vent 31 is not provided. That is, in FIG. 3B, the air between the mount 20 and the film 50 is evacuated by the vacuum pump 64 via the parts A and B. However, it takes time because vacuuming that penetrates the mount 20 cannot be expected.

On the other hand, if the ventilation holes (FIG. 1, reference numeral 31) are provided, the vacuum drawing through the mount 20 becomes active, and the skin pack is performed in a short time.
Therefore, it is recommended that the mount 20 be provided with the ventilation holes 31.

As the mount 20, a paperboard, corrugated cardboard, other paper or a resin sheet can be adopted.
However, when the article 40 is a precision part or a material processed with high precision, corrugated cardboard having a function of absorbing impact is suitable.

The present invention is suitable for a skin pack package in which an article is placed on a mount, and the film is attached to the upper surface of the mount while covering the article with a film.
