Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label affixed to the surface of a lid constituting a packaging container and displaying a description of the contents, a manufacturer's name, and the like. In particular, the present invention relates to a label for a packaging container having a function of releasing gas generated in the packaging container. 2. Description of the Related Art Labels for packaging containers not only indicate the type of contents to be packed, but also indicate the description of the contents, the name of the manufacturer, and the like. It is possible to use a general-purpose packaging container without preparing a packaging container. That is, labels for packaging containers are very useful for reducing packaging costs. When the contents are hermetically sealed by a packaging container consisting of a container body and a lid, depending on the contents such as pickles and miso, gas is generated as the fermentation proceeds, and this gas is generated by the container body. Or inflate the lid. If the container body or the lid body expands and deforms due to the gas, it becomes unstable when a large number of packaging containers are stacked on a display shelf or the like, and as the fermentation progresses, the product collapses or a large amount of products cannot be stacked. This is a common phenomenon with gas-producing ones, such as coffee. [0004] In order to prevent the above-mentioned phenomenon from occurring, it is only necessary to perform "gas release".
775. According to the technology proposed in this publication, the description of the claims of the utility model registration states that “in a hermetically sealed packaging container comprising a hard container body and a lid that is in close contact with the rigid container body, A packaging container for fermented food, characterized in that a perforation is formed at an appropriate place and a microporous sheet made of synthetic resin and / or a nonwoven fabric or paper that closes the perforation portion is adhered. Since the generated gas is gradually discharged from the “synthetic resin microporous sheet” portion, it is considered that the “bulging of the container due to the gas” as described above disappears. [0005] Incidentally, a "synthetic resin microporous sheet" proposed in Japanese Utility Model Laid-Open No. 1-100775 has been proposed.
Is directly adhered to the lid so as to cover the small holes perforated at appropriate places on the lid, so naturally it does not function as a `` label '', and the sticking or adhering work is not possible. It will be very hard. This is because the sheet is very small in view of the drawings and the like in the above publication, and this small sheet must be adhered so as to close the small hole portion of the lid. [0006] On the other hand, the "label" naturally displays various types of information, and must be affixed to a large number of commodities, that is, packaging containers packed with contents. Therefore, if possible, it is convenient if the label can be mechanically attached to the packaging container. In recent years, as shown in FIG. 4 (3), a large number of these pieces are temporarily pasted in a state of being arranged on release paper, and this is put on a machine schematically shown in FIG. It has already been done to mechanically stick one by one onto the incoming packaging containers. In other words, it is becoming an important condition or requirement that a label of this kind can be mechanically attached. In addition, as for the label to be affixed to the packaging container, the operation is simpler with one sheet, and the ratio of covering the lid is small. Therefore, the present inventors have conducted various studies on "labels" originally attached to the surface of the lid, and how to make the "gas release function" also exert. As a result, the present invention has been completed. SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and the problem to be solved is, of course, that various indications of the contents can be performed. An object of the present invention is to provide a label having a simple structure, which can exert a degassing function only by being attached to an upper surface of a lid provided with a label and can be easily manufactured. In order to solve the above problems, the means adopted by the present invention will be described with reference numerals used in the embodiments described below. The label 10 is used for a packaging container 20 composed of a container body 21 and a lid 22 for hermetically sealing the container, and has a notch 12 that surrounds a gas vent hole 23 provided in the lid 22. And the base material 11 to be stuck on the lid 22 and the base material 11
A ventilation material 13 attached to the top and covering the notch 12, so that when affixed on the lid 22, the gas vent hole 23 on the lid 22 side can be covered by the ventilation material 13. Label 10 ". [0010] That is, the label 10 is composed of the base material 11 and the ventilation material 13. Since the ventilation material 13 covers the notch 12 formed on the base material 11 side, the label 10 has Most of the surface of the material 11 can be used as a place for printing a pattern or display. In other words, the label 10 exhibits the original function of the “label” by the base material 11, and the original function is not hindered by the ventilation material 13 affixed thereon. As shown in FIG. 1, the label 10 is affixed on a lid 22 provided with a gas vent hole 23. It is attached so as to face the formed notch 12. Notch 12
Is covered with the ventilation material 13, but the gas vent hole 23 on the lid 22 side and its position can be visually recognized through the label 10. The reason is that the air-permeable material 13 of the embodiment to be described later is formed of, for example, a thin nonwoven fabric as a material having air permeability, and a pattern or the like printed on the surface of the base material 11 can be seen through.
This is because the position of the notch 12 on the side can be seen. Notch 1
If the formation position of the label 2 is set to the center of one side as shown in FIG. 1 or the like, or to the completely center as shown in FIG.
The label 10 in which the notch 12 on the zero side is aligned with the gas vent hole 23 on the side of the lid 22 can be easily attached. The ventilation material 13 is provided on the lower surface of the adhesive 13.
As shown in FIG. 3, the adhesive 13a is directly applied to the cover 22 at the notch 12 as shown in FIG. Therefore, the label 10 is stuck on the lid 22 without a gap, and a part of the contents does not leak out from the gas vent hole 23 on the lid 22 side. As described above, if the notch 12 is aligned with the gas vent hole 23 on the lid 22 and the label 10 is affixed on the lid 22, the gas vent hole 23 on the packaging container 20 will be It is covered by a gas permeable material 13 such as nonwoven fabric on the side. Therefore, the gas generated by fermentation of the contents in the packaging container 20 is discharged to the outside through the vent holes 23 and the ventilation material 13. Further, as shown in FIG. 4C, a large number of the labels 10 are temporarily affixed in a state where they are arranged on release paper 30, and this is applied to a machine schematically shown in FIG. Multiply,
One by one is mechanically affixed to the packaging container 20 sent one after another. That is, the label 10 according to the present invention can be mechanically attached. In order to enable this mechanical attachment, as shown in FIG. 5, a protruding portion 10a for enabling mechanical (of course, manual) picking is automatically provided at the front end of the leading label 10. Must be formed. Label 1 of the present invention
0, the base material 11 is formed of a material having a certain degree of rigidity such as paper.
Is formed by a simple roller as shown in FIG.
Multiplying by zero is easy. Therefore, this label 10 is used for the packaging container 2.
It goes without saying that various indications can be made on the contents in the area 0. In addition to the easy attachment by the machine on the lid 22, the ventilation to be attached on the gas vent hole 23 on the lid 22 side. "Degassing" can be performed by the material 13, and the packaging container 20 does not expand. Of course, it goes without saying that this label 10 can be applied not only to the above-mentioned “container” but also to “bag”. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the embodiments shown in the drawings. FIG.
2 shows a state in which the label 10 according to the present invention is about to be attached to the surface of the lid 22 fitted to the container body 21 constituting. As shown in FIGS. 1 and 3, the lid 22 is formed with a gas vent hole 23 large enough to prevent the contents from jumping out. As shown in FIGS. 2 and 3, the label 10 has a notch 12 surrounding a gas vent hole 23 provided in a lid 22, and a base material adhered on the lid 22. 11
And a ventilation material 13 attached to the base material 11 and covering the notch 12. The base material 11 of the present embodiment is made of so-called "paper" in order to make it easy to print a pattern or display on the front surface. An adhesive 11a is applied so that it can be stuck on the side of the body 22 or on the release paper 30 shown in FIG.
On the other hand, the ventilation material 13 is made of “non-woven fabric” in order to make the air permeability sufficient, but the entire back surface thereof can be attached on the base material 11 or the lid 22. Adhesive 13a is applied. The adhesive applied to the back surface of the nonwoven fabric functions without absorbing liquid. Further, since the base material 11 determines the shape of the entire label 10, not only the square shape shown in FIGS. 1 and 2 but also the circular shape shown in FIG. Or various shapes such as a diamond shape shown in FIG. The base 11 is formed with a notch 12 for exposing a part of the ventilation material 13 to the gas vent hole 23 on the lid 22 side. The notch 12 is formed slightly larger than the gas vent hole 23 on the lid 22 side.
In order to sufficiently form the protruding portion 10a shown in FIG. 5 and described above, a portion of the rigid base material 11 must be formed above the notch 12 shown in FIG. Is what is done. Conversely, (1) in FIG.
As shown in FIG. 6, the illustrated lower portion of the notch 12 may be long, and as shown in (2) of FIG. It may be present. Of course, as shown in (3) of FIG. 6, the notch 12 formed in the base material 11 may be located at the center of the base material 11, and these are shown in FIG. 7 or FIG. This can be said for the base material 11 having the shape shown in FIG. As for the adhesive 11a on the base material 11 side and the adhesive 13a on the ventilation material 13 side, it is sufficient to select a material inferred from the above-mentioned functions. The above label 10 is manufactured by a method as shown in FIG. First, as shown in FIG. 4A, a base tape 14 on which a predetermined pattern or display is printed is continuously attached onto a long release paper 30. Each notch 12 is cut out continuously while performing trimming. When each notch 12 is cut out, as shown in (2) of FIG. 4, the ventilation material tape 15 is continuously attached onto the base tape 14 and the release paper 30 while completely covering the notch 12. I will do it. Then, as shown in FIG. 4C, each label 10 is cut into a predetermined shape at the same time as the trimming of each ventilation material tape 15. As a result, a large number of the labels 10 as shown in FIG. What is important here is that the left-right direction shown in FIG. 4 is the feed direction when the release paper 30 is hung on the machine, and each notch 12 is opened in a direction orthogonal to this feed direction. It is that you are. This is because, when each label 10 is mechanically peeled off the release paper 30, a protruding portion 10a as shown in FIG. The nonwoven fabric may be sandwiched between the release paper 30 and the ventilation tape 15. As described above in detail, in the present invention, as exemplified in the above embodiment, "a package for sealing a content, comprising a container body 21 and a lid 22" A label 10 used for a container 20, comprising a notch 12 surrounding a gas vent hole 23 provided in a lid 22, a base material 11 affixed on the lid 22, 11
