[Problems to be Solved by the Invention]
No. 297, Japanese Patent Application Laid-Open No.
No. 207922, the pre-opening portion is formed by a perforation in the longitudinal direction, and the pre-opening portion is formed by opening the pre-opening portion by breaking the perforation in the longitudinal direction. A two-step process of breaking the transverse perforation and opening the sealing package is essential. In the former sealing label, there is a problem that it is difficult to pull the upper edge of the sealing label material, and it is necessary to apply a large force to a particularly small portion, and it is difficult for a child or an elderly person to open the sealing label. . The latter packaged container has a tensile pull tab for opening the pre-opening portion along the vertical perforation, but it is necessary to break the horizontal perforation to open the sealing package. The problem remains that it is difficult to pull the upper edge of the body.

Further, for the above-described reason, the force applied to break the horizontal perforations is dispersed, and the tensile force for opening the package is changed at the intersection of the vertical perforations and the horizontal perforations. Is not effectively concentrated at the opening point of opening), and as a result, the sealing label material or package breaks away from the horizontal perforation when the horizontal perforation breaks, resulting in a very poor appearance. May be. The present invention has been made in view of the above-described problems of the conventional sealing packaging, and can easily break not only the vertical perforations but also the horizontal perforations in one operation, and can be opened. It is an object of the present invention to provide a sealing package in which the sealing package is not likely to be broken in a direction deviating from a horizontal perforation.

SUMMARY OF THE INVENTION The sealing package of the present invention has been made in view of the above problems, and has a first breaking line;
In a sealing package having the first breaking line and a second breaking line intersecting, breaking the first breaking line and then breaking the second breaking line to open, the packaging film is obtained by polymerizing and bonding the packaging film. A breaking guide means, comprising a bonding portion, for guiding a break along the first break line to an intersection where the first break line and the second break line intersect, and from the intersection along the second break line. And a rupture direction changing means for changing the rupture direction in the direction indicated by the arrow. With this configuration, the break along the first break line is guided by the break guide means to the intersection of the first break line and the second break line. The breaking guide means prevents the sealing package from breaking in a direction deviating from the first breaking line, and applies a breaking force for advancing the breaking along the first breaking line to the first breaking line and the second breaking line. Efficiently concentrate at the intersection of the break lines. By making the breaking guide means a bonded portion where both ends of the packaging film are bonded together by polymerizing, a special process for forming the breaking guide means is not required, and the sealing is excellent in opening property at low cost. You can get the packaging. Of course, as long as it can guide the break along the first break line, the break guide means attaches a film or other reinforcing member having a higher breaking strength to the packaging film as compared to the packaging film. It may be.

Since the breaking point changing means is provided at the intersection, the breaking direction concentrated at the intersection is changed in the breaking direction by the breaking direction changing means. That is, the breakage proceeds in the direction along the second break line, and the sealing package is opened. As the breaking direction changing means, there is a breaking line continuous to a second breaking line, such as a perforation or a half-cut line, or a notch or the like, which facilitates partial breaking of the packaging film. Further, in addition to the above-described breaking guide means and breaking direction changing means, a breaking prevention means may be provided on an extension of the first breaking line. This breaking prevention means
As long as the breaking along the first breaking line can be prevented from proceeding more than necessary, the packaging film may be reinforced by polymerizing and bonding, or may be a film having a high breaking strength or other reinforcement. The member may be attached to a packaging film. By providing the breaking prevention means, the breaking force can be more efficiently concentrated at the intersection, and the breaking direction can be more reliably changed to the desired direction by the synergistic action with the breaking direction changing means. Can be more easily and reliably opened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A container provided with a sealing package according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG.
FIG. 1 is a perspective view of a container provided with sealing packaging according to the first embodiment of the present invention. The container 1 includes a container body 10 and a lid base 12 screwed to an upper portion of the container body 10. Although not shown, for example, a spouting hole is provided at the upper end of the container body 10, and the spouting hole is exposed by removing the lid base 12 from the container body 10, and the food or medicine filled in the container body 10 is opened. In addition, it is possible to shake out fillers such as cosmetics.
In addition, a vertical projection 32 is formed around the lid base 12 to facilitate the rotation of the lid base 10 with respect to the container body 10.

After filling the container body 10 having the above structure with a filling material, screwing the lid base 12 onto the container body 10, and then printing a product name or the like on the container body 10 or the like, the heat-shrinkable film S is a packaging film. , And heated and wound around the container body 10 as shown in the figure, and sealing packaging is performed. The thickness of the heat-shrinkable film S is desirably 0.25 mm or less, and the material thereof is polypropylene, polyethylene,
Examples include polyvinyl chloride, polystyrene, and polyethylene terephthalate. The heat shrinkable film S has a container body 1
Below the boundary line between 0 and the lid base 12, a horizontal perforation 42 as a second break line is formed over the entire circumference of the lid base 12. Further, the cylindrical heat-shrinkable film S
Is formed by winding a flat heat-shrinkable film S into a cylindrical shape, and bonding the start edge and the end edge by polymerizing and bonding with an adhesive or heat welding. Accordingly, when the heat-shrinkable film S is put on the container 1, the bonding portion 45 as the fracture guiding means is formed in the vertical direction with respect to the container 1. The horizontal perforations 42 are formed so as to cross the bonded portion 45 before bonding the heat-shrinkable film S. That is, in this embodiment, a portion of the lateral perforation 42 that crosses the bonding portion 45 constitutes a breaking direction changing unit.

The vertical perforations 41 extend downward from the upper end opening of the heat-shrinkable film S along the bonding portion 45, and the terminal ends thereof intersect with the horizontal perforations 42 near the bonding portion 45. The intersection of the vertical perforation 41 and the horizontal perforation 42 is indicated by reference numeral 40 in FIG. This intersection 40 coincides with the lower end of the vertical perforation 41. The longitudinal perforations 41 are opened in the sealing package opening direction of the bonding portion 45 (in this embodiment, in FIG. 1) so that the break is reliably guided to the intersection 40 by the bonding portion 45 when the sealing package is opened. Counterclockwise direction). Further, a tension tab 51 is formed at the upper end of the bonding portion 45 to pull the heat-shrinkable film S when breaking the heat-shrinkable film S along the longitudinal perforations 41. In this embodiment, an auxiliary tension tab 52 is provided in addition to the tension tab 51. This auxiliary tension tab 5
2 is, for example, when pulling the tension tab 51 to open the sealing package, the sealing tab is broken in the vicinity of the pull tab 51 or the pull tab 51, and it becomes difficult to continue the opening of the sealing package. This is useful in that the opening of the sealing package can be continued using the auxiliary tension tab 52. Also, the auxiliary tension tab 52
Is obtained by folding the heat-shrinkable film S in two and pulling the tension tab 51.
Can be formed at the same time as forming, and the cost of the sealing package is not increased.

An arrow 60 is a tension direction indicating means which is printed at a prominent position on the surface of the heat shrinkable film S and indicates the tension direction of the tension tab 51. Not only the arrow 60 but also a character or a combination of an arrow and a character may be used as long as the direction of the pull is specified. Next, a method of opening the sealing package of the present invention having the above configuration will be described. First, the tension tab 51 is lifted and pulled in the direction indicated by the arrow 60 on the front side of the container 1. As a result, the longitudinal perforations 41 are broken, but the bonding portion 45 plays the role of a guide and reliably guides the breakage of the heat-shrinkable film S to the intersection 40. As the breakage of the heat-shrinkable film S approaches the intersection 40,
The force for breaking the longitudinal perforations 41 (breaking force) gradually moves in the circumferential direction of the container 1, and when the break reaches the intersection 40, all the breaking forces concentrate on the intersection 40. Since a part of the horizontal perforation 42 is formed in the bonding portion 45, the breaking force concentrated at the intersection 40 is directed in the direction along the horizontal perforation 42, and thereafter, the lateral perforation 4
The breakage of the heat-shrinkable film S progresses counterclockwise in FIG. In this way, the sealing package can be reliably opened.

FIG. 2 shows a second embodiment of the present invention.
It is a perspective view of the container which performed sealing packaging. 2, the same parts and members as those of the container of FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the first embodiment, the vertical perforations 41 are described as extending vertically in the vertical direction in parallel with the bonding portion 45. However, in the second embodiment shown in FIG. Fitting part 4
5 are formed in a diagonal direction away from the center. Tension tab 5
1 'is provided on the bonding portion 45 side (opening side) with respect to the intersection of the longitudinal perforation 41' and the peripheral edge of the opening of the heat-shrinkable film S. In this embodiment, the tension tab 5
When 1 'is pulled, the tensile force causes the longitudinal perforation 4
1, the heat-shrinkable film S is broken, but when the breakage of the heat-shrinkable film S along the longitudinal perforations 41 'reaches the intersection 40, the progress of the fracture along the longitudinal perforations 41 It is blocked by the bonding section 45. That is, in this embodiment, a part of the bonded portion 45 located on the extension of the longitudinal perforation 41 'constitutes a break prevention means. The breaking force generated by pulling the tension tab 51 'is efficiently concentrated on the intersection 40, and the perforations (lateral perforations 42) of the bonding portion 45, which is the breaking direction changing means.
2 starts a break in the counterclockwise direction in FIG. 2 along the lateral perforation 42. Thereafter, the sealing package is opened along the horizontal perforations 42.

The breaking prevention means is provided at the intersection 40 as shown by a virtual line 45a (two-dot chain line) in FIGS.
It can also be easily provided by forming a part of the lower bonding portion 45 wide. In the above-described embodiment, the fracture guiding means is described as the bonding portion 45 formed by polymerizing and bonding the heat shrinkable film S.
The breakage of the heat shrinkable film S was determined by the longitudinal perforations 41 and 4.
The breaking guide means is not limited to the above as long as the breaking guide means can be guided so as not to deviate from the direction along 1 '. For example, a separate film sheet or the like may be partially attached to the heat-shrinkable film S. Further, the perforations as the first and second breaking lines described above may be a penetrating shape punched from the front side to the back side of the heat-shrinkable film S, or a half which is thin and easy to cut. It may be cut. Further, the groove may be a continuous groove without being limited to perforations. Further, the heat-shrinkable film S may have a substrate layer and a laser absorption layer, and the laser absorption layer may be broken by a laser to form a break line.

Further, in the above-mentioned embodiment, foods, pharmaceuticals,
Although the present invention has been described using a container filled with cosmetics and the like as an example, the present invention relates to a heat-shrinkable book for a book having a hard cover, a CD case, a floppy case, a cassette tape case, a compact case of a foundation, a disposable chopstick, a confectionary with a bonus, etc. It is also applicable to film packaging.

[0014]

Since the sealing package of the present invention is constructed as described above, it is possible to break the packaging film not only along the longitudinal breaking line but also along the transverse breaking line in one operation. Further, there is no possibility that the packaging film is broken in a direction deviating from the vertical breaking line or the horizontal breaking line upon opening. Therefore, the sealing package can be easily and reliably opened, and the appearance of the sealing package is not spoiled. In particular, since the bonding portion formed by polymerizing and bonding the both ends of the packaging film is used as the breaking guide means, a special process for forming the breaking guide means is not required, so that the sealing package can be easily opened at a low cost. Can be obtained.
