Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lid of a sealed container that is fixed to a plurality of open rows of containers arranged in series and sealed in series, and more particularly, a lid of a sealed container provided with a dividing line for separating the sealed containers individually. About.
[0002]
[Prior art]
As for sealed containers, there is known a structure in which a flange portion is provided at the opening edge of the container, and a sheet-like lid is fixed to the flange portion and sealed, for example, packaging of food such as pudding and jelly Is used.
[0003]
Further, for example, as disclosed in Japanese Utility Model Publication No. 57-174375, a plurality of unit containers containing foods are arranged, and a single sheet-like lid is fixed to the opening row of the containers, and sealed in series. To be done. The lid is provided with a perforation between the unit containers, and the unit containers are individually separated from the perforations. In this case, there is a merit that diversification can be achieved by combining a plurality of products having different functions such as flavor and color into one.
[0004]
[Problems to be solved by the invention]
However, in such a sealed container lid, when separating a series of container rows individually, it tears off from the perforation, and also breaks the portion sealing the opening of the unit container. There was a problem.
[0005]
In other words, the perforations are provided as parting lines so that they can be easily separated. However, the perforations are set to such a strength that they are not unnecessarily parted even when subjected to an impact at the distribution stage. In some cases, the perforation line may tear off the line without tearing. When it is torn off from the perforation, it may cause a defect that breaks the opening (sealed portion) of the unit container.
[0006]
Therefore, a margin is set by setting the width of the part where the perforation is provided, that is, the width of the narrow part between the unit containers. However, even in that case, it cannot be completely prevented from tearing off from the perforation, and conversely, the width of the thin sheet-like part connecting a plurality of containers is expanded, so that it becomes a henna when handling. Therefore, a new problem occurs in strength.
[0007]
The present invention has been made in view of such circumstances, and when separating a plurality of arranged container rows individually, it can be easily separated without detaching from the dividing line, and on the other hand, An object of the present invention is to provide a lid for a sealed container capable of integrally connecting a plurality of arranged container rows with strength that does not separate even when subjected to some impact at the distribution stage.
[0008]
[Means for Solving the Problems]
In order to achieve the above-described object, the lid of the sealed container of the present invention is a single sheet that is fixed to an opening row of a plurality of containers, and is fixed to a flange portion formed on the opening edge of the container. In the lid of a sealed container having a plurality of sealing surfaces, and having a dividing line indicating a boundary that is separated individually between the rows of the sealing surfaces,
The dividing line is formed by disposing an initial dividing line that is intermittently fully cut at one or more locations at both ends of the boundary and providing a half-cut pattern at the center between the initial dividing lines at both ends. .
[0009]
In the lid of the sealed container of the present invention, the half-cut pattern is a closed pattern composed of two lined lines sandwiching the boundary and an intersecting line connecting ends of the lined line on the surface, and the boundary on the back surface. It is preferable to configure as a single half-cut line located above.
[0010]
In addition, it is preferable that the shape of the intersecting line is configured as a protruding shape that continues from the two arranged lines toward the initial dividing line, or a bent shape or a curved shape that protrudes toward the inside of the two arranged lines. .
[0011]
In addition, a half-cut pattern that circulates corresponding to the flange portion is provided on the front and back pairs on the seal surface, but the half-cut pattern does not close at one corner, and ends at each edge across the corner. The corner is connected to the slit pattern to be formed, and the corner is formed into a pinch piece to be picked when the lid attached to the container is peeled off.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a lid of a sealed container according to the present invention will be described with reference to the accompanying drawings.
[0013]
FIG. 1 is a perspective view showing a sealed container and a lid thereof to which an embodiment of the present invention is applied. 2 is a plan view of the lid of the sealed container of FIG.
[0014]
The lid body 1 is formed from a single sheet body, and is configured to be fixed to a plurality of open rows of containers 2 and hermetically sealed. In this embodiment, it is set as the structure which adheres the cover body 1 to the container 2 and 2 which arranged two. However, of course, the array of containers 2 sealed in series is not limited to two.
[0015]
The container 2 has a configuration in which a flange portion 20 is formed on the entire circumference of the opening edge, and the back surface (seal surface) of the lid 1 is fixed to the flange portion 20.
[0016]
The lid 1 has two connected sealing surfaces whose rear surfaces are fixed to the flange portion 20, and a dividing line 3 indicating a boundary to be separated is provided in a narrow portion of the arrangement of the sealing surfaces. The containers 2 and 2 can be separated individually by cutting the container.
[0017]
The dividing line 3 is provided with an initial dividing line 4 that is intermittently fully cut at one or more locations at both ends, and a half-cut pattern 5 is formed at the center by half-cut processing.
[0018]
The initial dividing line 4 is intermittently fully cut (cut), and the length and pitch of the full cut are formed in a predetermined setting according to the size of the container, and these should be set appropriately. Thus, a configuration capable of withstanding a relatively large cutting force is adopted.
[0019]
The half cut pattern 5 has a closed pattern formed by two parallel lines 50, 50 sandwiching the boundary to be separated and an intersecting line 51 connecting the ends of the parallel lines 50, 50 on the front surface. Is a half cut line 52 located on the boundary to be separated.
[0020]
The intersecting line 51 has a bent shape that protrudes toward the initial dividing line 4 continuously from the two parallel lines 50 and 50. However, the shape of the intersecting line 51 is not limited to this, and is opposite to the present embodiment, that is, a bent shape or a curved shape protruding toward the inside of the two parallel lines 50, 50, or the two parallel lines 50. , 50 may be combined to form a straight line, or a combination thereof.
[0021]
Each seal surface is provided with a half-cut pattern 6 that circulates corresponding to the flange portion 20 on the front and back pairs by half-cut processing. The half-cut pattern 6 is not connected to the edge at three corners, It is the structure which connects with the slit pattern 8 each terminated to an edge at each corner, and forms a knob 7 that is picked when the corner 1 is peeled off from the lid 1 fixed to the container 2. Here, the circulation pattern of the half-cut processing is set so that the back circumferential line 61 on the back surface side is formed on the container center side rather than the front circumferential line 60 on the front surface side. Therefore, by causing the pick piece 7 made of the slit pattern 8 that is easy to cut, the side of the half-cut pattern 6 that is continuous with this is also peeled off, and the seal portion that goes around the flange portion 20 can be opened. The seal at the opening of the container 2 is opened.
[0022]
Usually, in the half-cut processing at the boundary where separation is performed, the positions are shifted on the front and back sides to form a pair, and the cutting force for tearing the formed half-cut line depends on the shift width of the front and back sides. However, this half-cut processing does not require a relatively large cutting force as in the case of perforation processing, and can be configured to tear with a relatively small cutting force by appropriately setting the shifting width. In the present embodiment, the shift width between the two parallel lines 50 and 50 and the half cut line 52 and the shift width between the front and back circuit lines 60 and 61 are set appropriately, both of which are relatively small. It is set to tear with cutting force.
[0023]
That is, in the formation of the dividing line 3, the both ends of the separation boundary are made to be the initial dividing lines 4 and 4 which are intermittently fully cut at one or more places, and the strength is shared by setting to withstand a relatively large cutting force. By setting the central portion to the half-cut pattern 5, it is set to be torn with a relatively small cutting force.
[0024]
Therefore, when the separation line 3 is cut off, the end portion where the cutting is started is a strong initial cutting line 4 but is short in length, and can be torn on the forming line as shown in FIG. And since the following center part is the half cut pattern 5 torn with a comparatively small cutting force, it can be easily torn inside the formation pattern, and if it reaches the initial dividing line 4 at the opposite end, the separation start end Like the side, its length is short, so it can be torn on the forming line.
[0025]
As a result, when separating the serialized containers 2 and 2 from each other, it is possible to prevent the container 2 and 2 from being separated from the dividing line 3 and torn, and the part of the dividing line 3 can be easily separated.
[0026]
On the other hand, in the dividing line 3 which becomes a boundary, since the initial dividing lines 4 and 4 at both ends share the strength, a plurality of containers 2 and 2 arranged in a row can be integrally connected with sufficient strength.
[0027]
Furthermore, since the shape of the intersecting line 51 is a protruding bent shape that continues from the two parallel lines 50 and 50 toward the initial dividing line 4, when it is cut off at the dividing line 3, The parallel lines 50 and 50 can be guided correctly.
[0028]
Further, when separating the serialized containers 2 and 2 from each other, it is possible to prevent the container 2 from being separated from the dividing line 3 and torn, so that the width of the narrow portion can be set narrow. That is, normally, in the half-cut processing, it is necessary to form line patterns in pairs on the front and back sides. If two parallel lines 50 and 50 are provided on the front surface as in this embodiment, the position is also shifted on the back surface. 2 line patterns are required. However, as described above, since the front side is configured as a closed pattern, the half-cut line on the back side can be a single half-cut line located at the center. The width of the gap portion can be set narrow. And since the part which has connected the containers 2 and 2 in series has narrow width, rigidity becomes high and it is preferable also in terms of strength.
[0029]
By the way, one corner of the sealing surface of the lid 1 is formed on a knob 7 made of an easily cut slit pattern 8 that is continuous with the half-cut pattern 6. As shown in FIG. 4, the half cut pattern 6 that is continuous with this, that is, the seal portion that goes around the flange portion 20 can be opened, and the opening seal of the container 2 can be easily opened.
[0030]
【The invention's effect】
As described above, according to the present invention, the dividing line indicating the boundary to be separated is provided with an initial dividing line at both ends of the boundary, and a half-cut pattern is provided at the center between the initial dividing lines. In the formation of the parting line, both ends of the separation boundary share the strength with the initial parting line that can withstand a relatively large cutting force, and the center part has a half-cut pattern that tears with a relatively small cutting force. Share strength.
[0031]
Therefore, when separating with a parting line, the length of the end part where separation starts is a strong initial parting line, but the length is limited to a short length, so that it can be torn on the forming line. And since the central part that follows is a half-cut pattern that can be torn with a relatively small cutting force, it can be easily torn inside the formation pattern, and if it reaches the initial breaking line at the opposite end, Similarly, since the length is limited to be short, it can be torn on the forming line.
[0032]
As a result, when the series of container rows are individually separated, it is possible to prevent the container rows from being separated from the dividing line and torn, and the portion of the dividing line can be easily separated.
[0033]
On the other hand, at the dividing line serving as the boundary, the initial dividing lines at both ends share the strength, so that a plurality of arranged containers can be integrally connected with sufficient strength.
[0034]
The half-cut pattern is a closed pattern formed by two lines arranged on the front surface and two intersecting lines connecting the ends of the lines, and an intersection line connecting the end portions of the lines, and the back surface is formed as a single half-cut line located on the boundary. Therefore, the width of the part of the dividing line, that is, the width of the narrow part between the containers can be set narrow. And since the part which has connected the container in series needs only a narrow width, rigidity becomes high and it is preferable also in terms of strength.
[0035]
That is, in half-cut processing, it is usually necessary to form line patterns in pairs on the front and back sides. If two lines are provided on one side as in the present invention, the position is shifted to the other side as well. A line pattern of strips is required. However, since the one surface side is configured as a closed pattern here, the line pattern on the other surface side can be a single half-cut line located in the center, and therefore the width of the narrow portion between the containers. Can be narrowed.
[0036]
In addition, since the shape of the intersecting line is configured as a protruding shape that continues from the two aligned lines toward the initial dividing line, or a protruding bent shape or a curved shape that extends toward the inside of the two aligned lines, When separating, it is possible to correctly guide the tearing breaks to the part of the line.
[0037]
In addition, half-cut patterns that circulate on the seal surface corresponding to the flange portions are provided on the front and back pairs, but the half-cut patterns are not closed at one corner, but are slits that terminate at the respective edges across the corner. The corner is connected to the pattern, and the corner is formed into a picked piece to be picked when the lid attached to the container is peeled off. By causing this, a half cut pattern that is continuous with this, that is, a seal portion that goes around the flange portion can be opened, and the opening seal of the container can be easily opened.
