Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep-drawing type package.

[0002]

2. Description of the Related Art A conventional deep-drawn package is often used for vacuum packaging fresh food such as ham. That is, as shown in FIG. 1, a flat upper film 2 is covered so as to close an upper opening surface of a lower film 1 having a pocket portion 1a, and a peripheral edge is sealed (indicated by hatching) and closed. Thereby, the main body 3 is formed. Then, the article to be packaged 4 is stored in the pocket 1a. The planar shape of the main body 3 is rectangular, and four sides of the main body 3 are heat-sealed and sealed.

In vacuum packaging, heat sealing for the above four sides is performed in a vacuum chamber, so that a process of vacuuming the pocket portion 1a and a heat sealing process are performed in a series of steps. When it is desired to enclose an inert gas in the package, the inert gas may be filled and heat sealed instead of vacuum processing. Further, when the packaged object 4 is not a fresh food product or the like and the package does not require vacuum or gas replacement, there is a package that is heat-sealed without performing the above vacuum treatment or gas replacement.

[0004]

The above-mentioned conventional deep-drawing type package has the following problems. That is, the conventional deep-drawing type package could not stand alone.
Therefore, when such packages are to be displayed on shelves in a store, they are generally stacked flat. Then, due to the structure of the package, the article to be packaged 4 can be easily seen from the upper film 2 side, and advertisements and other designs are often printed on the upper film 2, but it becomes difficult to see when flat-stacked. .

When the surface on which the shelves are placed is inclined, the surface of the upper film 2 rises slightly, but the inclination angle cannot be increased, so that no significant effect can be expected. In addition, when a large number of packages are erected in a state in which they are in contact with each other in a shelf having walls erected on all sides, the erected state can be maintained if the shelf is full. However, if the number of packages present in the shelf is reduced by being sequentially taken out, the package will fall down.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and an object of the present invention is to solve the above-described problem and to stand up a display shelf or the like so that an upper film 2 faces the front. It is another object of the present invention to provide a deep-drawing-type package that can maintain the posture in a single unit.

[0007]

In order to achieve the above-mentioned object, in a deep-drawing type package according to the present invention, a first film having a concave pocket portion for accommodating an object to be packaged (in the embodiment, A "lower film"), and a flat second surface which is closed by heat-sealing at a predetermined peripheral edge position with the first film while closing the opening surface of the first film.
Film (corresponds to "upper film" in the embodiment)
And wherein a rib protruding outward is provided on one side surface of the pocket portion (claim 1).

In this case, the strength of the side surface of the pocket portion is improved by the rib, so that even if pressure is applied to the side surface (rib), the pocket portion is not easily crushed. Therefore, when the package body is erected with the side surface provided with the ribs facing down, the peripheral edges of the first and second films on the side surface provided with the ribs and the ribs come into contact with the floor surface (installation surface), and the erecting is performed. Keep state. That is, the package becomes independent. As a result, for example, when the display device is erected on the display shelf, the second film surface can be directed forward, and the printing and the packaged object provided on the second film surface can be easily visually recognized. The effect is improved. Further, by standing up, the area occupied by the installation can be reduced.

[0009] In order to stand up in this manner, the peripheral edges of the first and second films on the side surfaces on which the ribs are provided and the positions of the bottom surfaces of the ribs are close to each other by projection as viewed from the second film surface. Good to do. Therefore, for example, the outer surface of the rib may be an inclined surface that protrudes outward toward the bottom surface of the pocket portion. When the outer surface of the rib is not an inclined surface, it is preferable to reduce the width of the heat seal portion on the side edge on which the rib is provided.

[0010] Preferably, an openable and closable fastener is attached to one side opposite to the side face provided with the ribs, and the heat seal of the first and second films is formed at a film portion located outside the fastener. (Claim 2). In this way, airtightness can be maintained before opening. Then, once opened, a simple closed state can be maintained by closing the fastener.

Further, an unsealed portion is provided between a seal portion thermally sealed by a film portion located outside the fastener and the fastener, and the unsealed portion is formed along a boundary between the seal portion and the seal portion. It is more preferable to form a film cutting portion (corresponding to "perforation" in the embodiment) (claim 3).

[0012] With this configuration, in order to open the package, the film can be cut along the film cut portion (perforation or the like) so that the unsealed portion can be easily crossed. . Since the film is cut along the film cutting portion, it does not reach the seal portion side or the fastener side.

Further, the film cutting section can take various forms, for example, the sealing section can be separated from the unsealed section. By doing so, the seal portion located outside the fastener that becomes unnecessary after opening can be removed, so that it does not become an obstacle when opening and closing the fastener or taking out the packaged item after opening, improving workability I do.

[0014] More preferably, a suspension hole is formed in the seal portion. The “suspension hole” here means not only a completely punched through hole, but also, for example, a C-shape punched out film, although the film itself remains, and a display rod is formed there. Includes all that can be inserted. By doing so, the rod can be inserted into the hanging hole to suspend it as an exhibition form.

In the case of the structure in which the film cutting portion is provided as in claim 3, a part of the unsealed portion may be protruded toward the heat seal portion located outside the unsealed portion. In this case, the cut film portion is formed along the protruding portion of the unsealed portion.

In this case, when the sealing portion is cut off along the film cutting portion (perforation or the like), an unsealed portion partially protruding outward remains. Therefore, the zipper can be easily opened by grasping the remaining unsealed portion of the film and pulling the film in the direction in which both films are pulled apart (outside). When the film cut portions are formed on both films located at the unsealed portions, the sealed portions are removed. Therefore, the opening process becomes easier. In addition, the protruding portion formed in the unsealed portion may be provided at one location or at a plurality of locations. That is, a part does not mean one place, but means a certain part.

In order to obtain the same function and effect, for example,
A film cutting portion may be formed in one of the two opposite film portions constituting the unsealed portion, and the film may be cut along the film cutting portion to open the film. In other words, when a film cut portion is formed on one of the opposing films constituting the unsealed portion, the one film is cut so that the seal portion remains, but the outside of the fastener is removed. Has an unsealed portion, and a free film portion having a relatively large area, a portion of which protrudes outward, is formed. Therefore,
You can firmly pinch the protruding large area, and by pulling outward in the pinched state,
Fasteners can be easily opened.

* Definition of terms "Film cut portion" means a portion connected by, for example, perforating a film by partially cutting the film and separating the film on both sides of the film cut portion. To cut and break the film. However, the cut portions need not be at equal intervals, may be at irregular intervals, and the length of the cut portions may be either uniform or random. Also, for example, the portion of the film cutting portion formed along the protruding portion,
By making the previously cut length longer than other parts, the protruding part can be easily set in the free state.

[0019]

3 and 4 show a deep drawing type package according to a first embodiment of the present invention. As shown in the figure, this embodiment shows an example in which the present invention is applied to a deep drawing type package. That is, the main body 13 is formed by covering the upper film 12 so as to close the upper opening surface of the lower film 11 having the pocket portion 11a and sealing the peripheral edge (indicated by hatching) to close. . The packaged object 10 is placed in the pocket 11a.
Is stored.

The planar shape of the main body 13 is rectangular, and two longitudinal sides 13a and one lateral side 13b of the main body 13 are heat-sealed in total, and both films on the remaining one side 13c are formed. A fastener 14 is mounted between them. Thus, by closing the fastener 14, the article to be packaged stored in the pocket 11a is easily sealed.

The fastener 14 used here is Zipl
It is also called oc (zip lock) type, which has a male type and a female type, can be closed by pinching them with fingers, and can be opened by pulling them apart on the opposite side. Yes, it has been conventionally used as a simple closing (sealing) means after opening a bag or the like.

Further, the remaining one side 13c in the short direction, that is, the film portion where the fastener 14 protrudes largely is also sealed, and the sealed portion becomes the seal portion 15 in the present invention. The seal portion 15 and the seal portion formed on the two sides 13a in the longitudinal direction of the main body 13 are continuous, whereby the entire periphery of the package is sealed, and the package is hermetically sealed.

An unsealed portion 16 which does not seal the films 11 and 12 is formed between the fastener 14 and the seal portion 15. The unsealed portion 16 is formed in a straight line (band shape) along the fastener 14.

A perforation 17 as a film cutting portion is formed so as to cross the unsealed portion 16.
This perforation 17 is formed straight along the unsealed portion 16. That is, the unsealed portion 16 and the sealed portion 15
A perforation 17 is formed along the boundary between. Moreover, the perforations 17 are formed so as to penetrate the films 11 and 12.

Further, in this embodiment, a hanging hole 18 is formed at the center position of the seal portion 15, a rod provided on a display shelf is inserted, and the package can be displayed in a suspended state.

With this configuration, in order to open the package, the seal portion 15 is separated from the main body 13 by cutting along the perforations 17. As a result, FIG.
As shown in (2), the remaining unsealed portion 16 that is free exists outside the fastener 14. Then, the fastener 14 can be opened by pinching the free unsealed portions 16 and pulling them apart from each other. Thereby, the article to be packaged stored in the pocket portion 11a can be taken out.
When the packaged object remains, it can be closed by pinching the fastener 14 from both sides with fingers or the like.

Further, in the present embodiment, a rib 20 is provided at the center of the side surface of the pocket portion 11a opposite to the fastener 14. And this rib 20
Its outer surface is closer to the pocket 1 than the upper film 12 side.
It is formed so that the bottom surface side of 1a is an inclined surface 20a protruding outward (peripheral side of one side 13b). Thereby, when the position of the bottom side end 20b of the inclined surface 20a is viewed from the upper surface of the upper film 12, one side 13
The position is substantially the same as or slightly inside the periphery of b.

In this way, as shown in FIG. 6, when the package 13 is to be erected on the display shelf 21,
The bottom side end 20b of the rib 20 and one side 1 heat-sealed
The periphery of 3b contacts the display shelf 21. And rib 2
Since the strength is maintained by 0, the ribs 20 are not crushed, and the package body 13 is supported by the bottom end portion 20b and the peripheral edge of one side 13b, so that the standing state can be maintained.

On the other hand, in this embodiment, one rib 20 is provided at the center of the side surface. However, the present invention is not limited to this, and two ribs may be provided on both sides as shown in FIG. Three or more may be provided. In the case of the package shown in FIG. 7, the outer surface 20c of the rib 20 is formed not perpendicularly to the film surface of the upper film 12, as shown in FIG. Also in such a configuration, as shown in FIG. 7, the widths of the upper and lower films 12, 11 on the side where the rib 20 is provided (one side 13b) may be narrowed (the package can be erected in a stable state). .

In addition, when this standing state is established,
The packaged object 10 comes into contact with the surface on which the ribs 20 are not formed among the side surfaces (surfaces on which the ribs 20 are provided) of the pocket portion 11a on the side 13b side, and does not further descend. Therefore, rib 2
The formation position and the number of formations of 0 can also be determined according to the relationship with the article to be packaged. In other words, when it is desired to support the package 13 at both ends when the package 13 stands, the rib 2
0 may be provided at the center. Conversely, when it is desired to support at the center, ribs 20 may be provided on both sides as shown in FIG.

FIG. 9 shows a second embodiment of the deep-drawing type package according to the present invention. As shown in the figure, the basic configuration is the same as that of the first embodiment. Here, in the present embodiment, the shape of the unsealed portion 16 is changed.
Along with this, the structure of other parts is also changed.

That is, most of the unseal portion 16 is formed in a straight line (strip shape) along the fastener.
A semicircular protruding portion 16a is provided, a part of which protrudes toward the seal portion 15 side.

A perforation 17 is formed so as to cross the unsealed portion 16. That is, in the perforation 17, the straight portion is formed straight in the direction in which the straight line extends, and the region of the protrusion 16 a corresponds to the protrusion 1.
It is formed in a semicircular arc shape according to the shape of 6a. That is, the perforations 17 are formed along the boundary between the unsealed portion 16 and the sealed portion 15.

With this configuration, in order to open the package, the seal portion 15 is separated from the main body 13 by cutting along the perforations 17. As a result, FIG.
As shown at 0, a free unsealed portion 16 exists outside the fastener 14. Then, the fastener 14 is opened by pinching the protruding portions 16a and pulling them apart from each other. Thereby, the article to be packaged stored in the pocket portion 11a can be taken out. Since the projecting portion 16a has a relatively large area, it can be held firmly, and the fastener 14 can be easily opened by applying a force easily. In addition,
The other configuration and operation and effect are the same as those of the above-described first embodiment, and therefore, are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIGS. 11 and 12 show a deep drawing type package according to a third embodiment of the present invention. In the above-described embodiment, the seal portion is cut off. However, in this embodiment, a package is opened by cutting one side of the unsealed portion, and the seal portion remains after opening. .

That is, this embodiment is based on the second embodiment, and has perforations 17 only on the upper film 12. Thereby, the upper film 1
The second unsealed portion 16 is cut off along the perforations 17.
Then, the lower and upper films 1 in the seal portion 15 are formed.
Since the sheets 1 and 12 are connected to each other, the package is opened at the unsealed section 16 of the upper film 12 although the seal section 15 remains. Then, the fastener 14 can be easily opened by grasping the protrusion 16a and the seal 15 on the upper film 12 side and pulling them apart.

In the illustrated example, the perforations are formed at the same pitch over the entirety. However, the present invention is not limited to this. The cutting length may be uneven. For example, as shown in FIG. 13, for example, the cutting portion 17 a of the portion formed along the periphery of the protruding portion 16 a is lengthened and the connecting portion 17 b is reduced, so that the protruding portion 16 a can be easily cut off. You may make it easy.

Further, in the above-described second and third embodiments and modifications, the protrusion 1 provided on the unsealed portion 16 is provided.
6a, but the present invention is not limited to this.
For example, as shown in FIG. 14, the number may be two, or three or more. Further, the shape is also a semicircular shape in the illustrated example, but is not limited to this.

In addition, after the above-described second embodiment, the structure shown in the first embodiment (the rib is one).
), But the present invention is not limited to this.
It goes without saying that the present invention can be similarly applied to the modified examples (two ribs) shown in FIGS. 7 and 8 and those having three or more ribs.

Furthermore, the shape and the number of the ribs can be arbitrarily combined, and the outer surface of the rib in the first embodiment shown in FIG.
The outer surface of the rib of the form shown in FIG. Further, when a plurality of ribs are provided, a rib having an inclined surface and a rib having no inclined surface may be mixed.
