Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a label that is affixed to the surface of a lid constituting a packaging container and displays a description of the contents, a manufacturer's name, etc., and in particular, has a function of venting gas generated in the packaging container. It relates to labels for packaging containers.
[0002]
[Prior art]
The label for the packaging container displays the type of contents to be packed and at the same time displays the description of the contents and the name of the manufacturer. There is no packaging container for the contents. However, a versatile packaging container can be used. That is, the label for the packaging container is very useful for reducing the packaging cost.
[0003]
By the way, when the contents are sealed with a packaging container consisting of a container body and a lid, depending on the contents such as pickles and miso, gas is generated when the fermentation proceeds, and this gas is generated by the container body and lid. May be inflated. If the container body or lid is expanded and deformed by the gas, it becomes unstable when a large number of packaging containers are stacked on a display shelf or the like, and the product collapses or cannot be stacked in large quantities as the fermentation progresses. This is a phenomenon that is often seen for those that generate gas, such as coffee.
[0004]
In order to prevent the above phenomenon from occurring, it is only necessary to perform “gas venting”. However, as such a prior art, for example, it can be seen in Japanese Utility Model Laid-Open No. 1-100775. From the description of the scope of the utility model registration request, the technology proposed in this publication is:
“In a hermetically sealed packaging container comprising a rigid container body and a lid that is in close contact therewith, a microhole made of a synthetic resin in which a small hole is formed in the lid body at an appropriate location and the small hole portion is blocked. A packaging container for fermented foods characterized by adhering sheets and / or nonwoven fabric or paper "
Since the gas generated in the container is gradually discharged from the “synthetic resin microporous sheet” portion, it is considered that the “bulging of the container due to gas” described above is eliminated.
[0005]
By the way, the “synthetic resin microporous sheet” proposed in Japanese Utility Model Laid-Open No. 1-100775 is directly bonded to the lid so as to close the small hole portion formed in an appropriate portion of the lid. As a matter of course, the function as a “label” cannot be fulfilled, and the sticking or bonding work becomes very difficult. This is because this sheet is very small according to the drawings of the above publication and the like, and this small sheet must be bonded so as to close the small hole portion of the lid.
[0006]
On the other hand, the “label” must be affixed to a packaging container filled with a large number of products, that is, the contents, as a matter of course, for performing various displays. Therefore, if possible, it is convenient that the label can be mechanically applied to the packaging container side. In recent years, as shown in (3) of FIG. 4, a large number of sheets are temporarily pasted on a release paper, and this is applied to the machine schematically shown in FIG. It has already been done mechanically affixing one by one on a packaging container to be sent. In other words, it is an important condition or requirement that this type of label can be mechanically attached. In addition, a single label to be attached to the packaging container is easier to work, and the ratio of covering the lid is small.
[0007]
Accordingly, the present inventors have conducted various studies on how to make the “label” attached to the surface of the lid originally exhibit the “gas venting function”. The invention has been completed.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and the problem to be solved is that the contents can be displayed in various ways. The purpose of this invention is to provide a label with a simple structure that can exhibit a punching function and can be easily manufactured.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the means taken the inventions according to claim 1 is explained with reference numeral to use in the embodiments described below,
“A label 10 used for a packaging container 20 comprising a container body 21 and a lid 22 having a gas vent hole 23 for sealing the contents,
The base material 11 pasted on the lid body 22 and printed on the display, the notch 12 formed on the base material 11 at the position where the display is removed, and the base material 11 with the display removed. And a ventilation member 13 covering the notch 12,
Can a notch 12 is attached on the lid 22 so as to surround the vent holes 23, the label 10, characterized in that the gas vent holes 23 so as to obtain covered by breathable material 13 '
It is.
[0010]
That is, the label 10 is composed of the base material 11 and the ventilation material 13, but the ventilation material 13 covers the notch 12 formed on the base material 11 side. Most of this can be used as a place for printing patterns and displays. That is, the label 10 exhibits the original function of the “label” by the base material 11, and the original function of the label 10 is not hindered by the ventilation material 13 affixed thereon.
[0011]
As shown in FIG. 1, the label 10 is affixed on a lid body 22 provided with a gas vent hole 23. Of course, the gas vent hole 23 is formed in the base material 11. Affix it so that it faces a notch 12. The notch 12 is covered with the ventilation member 13, but the gas vent hole 23 on the lid 22 side and its position can be sufficiently visually recognized through the label 10. This is because the air-permeable material 13 of the embodiment described later is formed of, for example, a thin non-woven fabric as having air permeability, and the pattern printed on the surface of the base material 11 can be seen through. This is because the position of the notch 12 is visible. Further, the forming position of the notch 12, the central and the side, as shown in FIG. 1 or the like, if at all in the center as shown in (3) in FIG. 6, the label 10 side notch 12 of the cover body 22 side application of the combined label 10 to vent holes 23 is capable of performing the easy.
[0012]
In addition, although the ventilation material 13 is affixed on the base material 11 with the adhesive agent 13a of the lower surface, as shown in FIG. 3, this adhesive agent 13a is directly on the cover body 22 side in the notch 12 part. Will work. For this reason, this label 10 is affixed on the cover body 22 without a gap, and part of the contents does not leak out from the vent hole 23 on the cover body 22 side.
[0013]
If the label 10 is affixed on the lid 22 with the notch 12 aligned with the gas vent hole 23 on the lid 22 side as described above, the gas vent hole 23 on the packaging container 20 side becomes the nonwoven fabric on the label 10 side. The air-permeable material 13 having air permeability such as the above is covered. For this reason, the gas generated when the contents are fermented in the packaging container 20 is discharged to the outside through the gas vent hole 23 and the ventilation member 13.
[0014]
Also, as shown in FIG. 4 (3), the label 10 is temporarily affixed in a state of being arranged on the release paper 30, and this is applied to the machine schematically shown in FIG. It is affixed mechanically one by one on the packaging container 20 sent from one to the next. That is, the label 10 according to the present invention can be mechanically attached. In order to enable this mechanical sticking, as shown in FIG. 5, a protruding portion 10a is automatically provided at the front end of the leading label 10 so that mechanical (of course, manual) picking can be performed. Must be formed. In the label 10 of the present invention, the base material 11 is formed of a material having a certain degree of rigidity, such as paper. Therefore, the protruding portion 10a is formed on a release roller with a simple roller as shown in FIG. Multiply 30 and you can do it easily.
[0015]
Therefore, labels 10 according to claim 1 of this, the various displays can be performed on the contents of the packaging container 20 is of course a well performed easily is stuck due to mechanical on the lid 22, the lid The venting material 13 to be affixed onto the degassing hole 23 on the 22 side can perform “degassing”, and the packaging container 20 is not expanded. Of course, this label 10 can be applied not only to the above-described “container” but also to a “bag”.
[0016]
In order to solve the above problem, the means taken by the invention according to claim 2 is the label 10 according to claim 1,
“The notch 12 is formed at the center of one side of the base 11 or the center of the base 11”
It is.
[0017]
That is, in the label 10 of claim 2, the notch 12 is formed at the center of one side of the base 11 as shown in FIG. 1, or as shown in (3) of FIG. The center of
[0018]
If it does in this way, in label 10 of this claim 2, sticking of label 10 which matched notch 12 by the side of the label 10 with gas vent hole 23 by the side of lid 22 can be performed easily. Is.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in accordance with the embodiment shown in the drawings. FIG. 1 shows a label according to the present invention on the surface of a lid 22 fitted to a container body 21 constituting a packaging container 20. The state which is going to stick 10 is shown. As shown in FIGS. 1 and 3, the lid 22 is formed with a vent hole 23 having a size that prevents the contents from popping out.
[0020]
As shown in FIGS. 2 and 3, the label 10 has a notch 12 that surrounds a gas vent hole 23 provided in the lid 22, and a base material 11 that is affixed on the lid 22, A ventilation member 13 is provided on the base material 11 and covers the notch 12.
[0021]
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 surface, and the label 10 is placed on the lid 22 side on the entire back surface. Alternatively, an adhesive 11a is applied so that it can be applied to the release paper 30 shown in FIG. On the other hand, the air-permeable material 13 is made of “nonwoven fabric” in order to make the air permeability sufficient, but the entire back surface thereof can be stuck on the base material 11 or the lid 22. Adhesive 13a is applied. The adhesive applied to the back surface of this nonwoven fabric functions without absorbing liquid.
[0022]
Moreover, since this base material 11 will determine the shape of the label 10, the square shape as shown in FIG.1 and FIG.2 as well as the circular shape as shown in FIG.7, Or it can apply as a thing of various shapes, such as a rhombus thing shown in FIG.
[0023]
The base material 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. This notch 12 is formed slightly larger than the vent hole 23 on the lid 22 side, but is shown in FIG. 2 so that the protruding portion 10a shown in FIG. 5 and described above can be sufficiently formed. In the upper part of the notch 12 in the figure, a part of the base material 11 having rigidity is always present. Conversely, as shown in FIG. 6 (1), the lower portion of the notch 12 may be long, and as shown in FIG. 6 (2), the right side surface of the substrate 11 is shown. The ventilation material 13 made of a nonwoven fabric may extend slightly on the side. Of course, as shown in FIG. 6 (3), the notch 12 formed in the base material 11 may be located at the center of the base material 11, and these are the same as those shown in FIG. This is also true for the base material 11 having the shape as shown in FIG.
[0024]
In addition, it is sufficient to select the adhesive 11a on the base material 11 side and the adhesive 13a on the ventilation material 13 side from materials estimated from the functions described above.
[0025]
The above label 10 is manufactured by a method as shown in FIG. First, as shown in (1) of FIG. 4, a base tape 14 having a predetermined pattern or display printed thereon is continuously pasted on a long release paper 30. Each notch 12 is continuously cut out while trimming. If each notch 12 is cut out, as shown in (2) of FIG. 4, the ventilation tape 15 is continuously pasted 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. 4 (3), each label 10 is cut into a predetermined shape simultaneously with the trimming of each ventilation material tape 15. Thereby, a large number of labels 10 as shown in FIG. 2 are formed in a state where a large number of labels 10 are arranged on a single tape-shaped release paper 30. What is important here is that the horizontal direction shown in FIG. 4 is the feed direction when the release paper 30 is put on the machine, and each notch 12 opens in a direction perpendicular to the feed direction. It is that you are. This is because, when each label 10 is mechanically peeled off from the release paper 30, a protruding portion 10a as shown in FIG.
[0026]
Alternatively, the nonwoven fabric may be sandwiched between the release paper 30 and the ventilation material tape 15.
[0027]
