DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conical packaging container for packaging a substantially conical food such as ice cream or chocolate confectionery, and more particularly, to a container in which the apex of the conical food is downward. The present invention relates to a packaging container in which, while holding the lower half with one hand, the upper half of the container is torn off with the other hand and the upper half of the food is exposed to the outside and can be eaten.

[0002]

2. Description of the Related Art Heretofore, a conical packaging container for packaging substantially cone-shaped foods (contents) such as ice cream and chocolate confectionery, wherein the apex side of the conical shape of the contents is positioned downward. With the lower half held by one hand, the upper half of the container is torn off with the other hand, and the upper half of the contents is exposed to the outside and can be eaten. Are provided.

[0003] For example, a conical packaging container provided with a container tearing tab (knob) integrally formed on the conical surface forming wall of the container and substantially at the center of the container in the height direction of the container. (See Utility Model Registration No. 2597322)
Is provided. In this container, hold the lower half of the container with one hand so that the top side of the contents is down,
By pulling the tab with the other hand in a substantially horizontal direction (lateral direction) with respect to the conical surface forming wall (container body), the conical surface forming wall is torn to remove the upper half of the container and expose the upper half of the food to the outside. You can eat it.

However, in this packaging container, when the tab is pulled against the container body in order to remove the upper half of the container, for example, the tearing points (directions) with respect to the conical surface forming wall become random, and the contents are removed. The upper half cannot be uniformly exposed in an easily edible state, or a part of the conical surface forming wall that is torn integrally with the tab when the tab is pulled is cut carelessly on the way, There are problems such as difficulty in separating the upper half of the container from the lower half.

[0005] As a conical packaging container that solves this problem, for example, at a substantially central portion in the height direction of a conical surface forming wall,
A packaging container in which a pair of perforations are formed in parallel with each other in a circumferential direction around a central axis passing through the apex of the cone, and the pair of perforations serves as a tearing guide means for a conical surface forming wall (actually opened container). See Japanese Patent Application Laid-Open No. 55-156086). In this packaging container, the conical surface forming wall is torn along the perforations by pulling the tab provided substantially at the center in the height direction of the container in the horizontal direction with respect to the container body. Therefore, when the upper half of the container is removed,
The upper half of the food is uniformly exposed to the outside over the entire circumference, so that the lower half of the container does not interfere with eating the food.

However, in this packaging container, when the conical surface forming wall is torn as described above, the diameter of the lower end of the upper half of the container becomes the content (food) located in the upper half container. When the conical surface forming wall is torn over its entire circumference, the upper half container cannot be removed from the contents when the conical surface forming wall is torn over its entire circumference. That is,
In this type of packaging container, to remove (remove) the upper half of the container from the contents, tear the conical surface forming wall along the perforation along the entire circumference, and then further remove the upper half. It is necessary to tear or tear off the container at an appropriate place, which is very troublesome and troublesome.

[0007] As a conical packaging container which solves this problem, for example, a pair of perforations parallel to each other are formed as non-concentric circles with respect to the apex of the cone as tearing guide means for the conical surface forming wall, In other words, the container is formed obliquely with respect to the horizontal direction (lateral direction) of the container body, and each perforation is formed inside the container at a position where the upper end (end point) of the perforation is substantially halfway around the container body with the tab as a reference position. Conical packaging container (Utility Model Registration No. 25) formed so as to be positioned below and near the upper end of the conical food stored in the container.
No. 06398). In this packaging container, when a tab provided substantially at the center in the height direction of the container is pulled substantially obliquely upward along the perforation with respect to the container body (that is, the conical surface forming wall), first, the conical surface is formed. The formation wall is gradually torn obliquely upward with respect to the container body along the perforation formed in advance, and the corner of the container is torn. Further, when the tab is pulled up obliquely upward, the torn portion of the conical surface forming wall reaches the upper end of the perforation when the tab is substantially halfway around the container main body. From this state, the tab is further pulled up obliquely upward. With the lower perforation as the lower end of the upper half of the container, the upper half of the container is forcibly torn from the lower half of the container. That is, in this packaging container, by pulling up the tab, the upper half of the container can be torn from the lower half of the container in which the food is stored with one touch.

However, in this packaging container, since the perforations are formed obliquely to the horizontal direction of the container body, when the tab is pulled to tear the upper half of the container from the lower half, a conical shape is formed. The contents are not uniformly exposed to the lower half of the container over the entire circumference, or the upper end (upper edge) of the lower half of the container is partially above the upper end of the contents. It remains as an extended amorphous piece, and the contents are hardly eaten.

In each of the packaging containers, the tearing start position (the position of the tab) of the container is located substantially at the center in the height direction of the conical wall, that is, the container body, and the tearing direction is the container body. This is a type of packaging container that is generally horizontal or obliquely upward, but unlike this type, the tearing start position of the container (position of the tab)
There has been conventionally provided a packaging container of a type in which the container is located at the upper end of the container and whose tearing direction is obliquely downward with respect to the container body (see Japanese Utility Model Publication No. 49-40716). In this type of packaging container, a perforation as a tear guiding means is formed in a spiral shape from the upper end of the container toward the vertex of the cone. Here, for example, when the conical packaging container is formed from one substantially fan-shaped blank, a product in which the conical food is stored / sealed inside is formed by first rounding the blank and removing one of the blanks. A first step of adhering the parts corresponding to the pair of fan-shaped side parts to each other, and then a substantially conical food (content)
In the semi-finished packaging container,
Then, a blank portion corresponding to the upper end portion of the food is radially brought together from three or four directions, and a third step of bonding the inner surfaces of the blanks facing each other is performed. In the third step, when the blank portion forming the upper end portion of the container is squeezed radially from three or four directions as described above, the sheet member forming the upper end portion of the container has the fulcrum at the upper end of the conical surface of the food. As
Considerable tension acts. Therefore, in the case where the packaging container as described above, in which the tearing direction is obliquely downward with respect to the upper end of the container body, is thus formed from one fan-shaped blank, in the third step,
The sheet member forming the upper end of the container may be broken at a perforation provided at the upper end.

[0010]

Accordingly, the technical problem to be solved by the present invention is to simply pull the tearing tab against the main body of the packaging container and, with one touch, move the upper half of the container to the lower half. A conical packaging container that can be torn apart and, at the same time, can uniformly expose the generally conical food stored in the packaging container to the lower half of the container over the entire circumference. To provide.

[0011]

In order to solve the above technical problems, according to the present invention, the following conical packaging container is provided.

That is, the conical packaging container has a tearing tab at an intermediate portion of the conical surface forming wall for tearing the conical surface forming wall substantially in the lateral direction. The conical surface forming wall is connected to one end of the tab located on the conical vertex side, and is provided in a ring shape in the circumferential direction of the conical surface forming wall, that is, in a circular shape in which the ends are connected. A first break line, a second break line provided on the opposite side of the apex of the cone with respect to the first break line and connected to the other end of the tab, wherein the first break line extends in the tear direction of the tab. And a second break line having an end point below and near one end of a conical surface opposite the vertex of the cone of food contained in the container and tapered away from the container.

In this configuration, the upper end of the container, that is, the end located on the side opposite to the apex of the cone, is formed, for example, as a substantially flat portion, a substantially semicircular portion, or an irregularly shaped portion. Can be The irregular portion is formed, for example, by radially assembling upper end forming walls connected to the free ends of the conical surface forming walls located on the opposite side of the apex of the cone from a plurality of directions such as three directions and four directions. It can be formed as a shaped irregular part.

This packaging container is used as follows.

First, while holding the lower half of the conical surface forming wall of the container with one hand, that is, the portion of the conical surface forming wall on the apex side of the cone, the tearing tab is held on the conical surface forming wall with the other hand. On the other hand, pull it roughly in the circumferential direction. With this operation,
The conical surface forming wall is simultaneously torn along the first and second break lines starting from one end and the other end of the tab, but the end point of the second break line is the upper end of the conical surface of the food, that is, the food. For example, if the conical surface forming wall is further forcibly torn beyond the end point of the second breaking line, the conical surface of the food is formed below the one end of the conical surface opposite the apex of the conical surface. A portion of the upper end of the surface begins to be exposed, triggering the release of the upper half of the packaging container from the upper end of the conical surface of the food. And, from this state, when further tearing the conical surface forming wall, the opening diameter including the second break line of the upper half of the packaging container becomes larger than the outer diameter of the upper end of the conical surface of the food, The upper half of the packaging container is released to the upper end of the conical surface of the food. On the other hand, at the same time, the conical surface forming wall is torn in the circumferential direction along the first breaking line, and when the tear makes one round of the circumference, the upper half and the lower half of the container are: Completely separated from each other.

According to the above construction, the first breaking line has a function of separating the upper half (part on the substantially flat surface side) and the lower half (part on the vertex side) from each other. On the other hand, the second breaking line has a function of opening the upper half of the packaging container from the upper end of the conical surface of the food stored in the packaging container. The other end and the end point of the second breaking line are provided at positions different from each other, and the tearing tab is pulled in the circumferential direction with respect to the packaging container main body, so that the conical surface forming wall is formed on the entirety of the first breaking line. When torn along the circumference, the tabs remain together as part of the upper half of the packaging container. Therefore,
With a single action of pulling the tab in a generally horizontal circumferential direction, with one touch, the upper half of the packaging container is separated from the lower half and released from the upper half of the food product.

Further, according to the above configuration, the first breaking line is connected to one end of the tab and provided continuously in a ring shape in the circumferential direction of the conical surface forming wall. Therefore, by pulling the tab in a substantially horizontal circumferential direction and tearing the conical surface forming wall along the entire circumference of the first breaking line, the generally conical food stored in the packaging container can be placed under the container. For half,
It is uniformly exposed over the entire circumference of the conical surface.

That is, the upper half of the container can be torn to the lower half with one touch only by pulling the tearing tab against the body of the packaging container, and at the same time, the tearing tab is stored in the packaging container. The substantially conical food can be uniformly exposed all around the lower half of the container.

Further, for example, when the packaging container is formed of a single substantially fan-shaped blank made of a sheet-like member, the blank is rolled to form a portion corresponding to a pair of fan-shaped side surfaces of the blank. After the food is stored in a semi-finished container formed by bonding the blanks to each other, the blanks are radially brought together from three or four directions at the portion corresponding to the upper end of the food and the mutually facing inner surfaces are bonded to each other. When formed, considerable tension (tension) acts on the assembling portion (upper end portion) including the portion that comes into contact with the upper end of the conical surface of the generally conical food, with the upper end of the conical surface of the food as a fulcrum. However, according to the above configuration, the second
Since the end point of the breaking line is provided at a position corresponding to the lower portion near the upper end of the conical surface of the food, that is, the second breaking line is provided at a position where the tension is unlikely to act,
The sheet member forming the container is effectively prevented from being inadvertently torn along the second break line.

In the above configuration, the break line can be formed by intermittent cuts such as perforations and half cuts.

In the above construction, each of the cuts is provided with a base line extending in the tearing direction, and an auxiliary connecting to the tearing start point of the base line and inclined at an obtuse angle to the base line in a direction opposite to the tearing direction. It is preferably formed from a line portion.

According to this configuration, when the conical surface forming wall is torn, a tear that progresses from the end point of the base line portion between the end point of the specific base line portion of the cut and the start point of the next base line portion in the tearing direction. Even if the tip of the slit deviates from the starting point of the next base line, the tip of the split reaches the auxiliary line of the next cut, so that the traveling direction of the split is connected to the auxiliary line by the auxiliary line. It is guided and corrected in the direction of the starting point of the base line. Therefore, with this configuration, the conical surface forming wall is torn more faithfully along the first and second break lines.

In each of the above constructions, the conical surface forming wall is formed of a sheet member, and the sheet member is formed of a paper layer and a tear that is laminated on the paper layer and guides the tearing of the sheet member along the break line. It is preferable that the substrate has a base layer provided with a guide resin layer, and the break line is formed by intermittent cuts formed from perforations penetrating the base layer. In this configuration, the paper layer imparts shape retention to the packaging container, for example.

In general, a paper layer is liable to cause delamination at the time of tearing, and when the delamination occurs, the tear direction is deviated from a predetermined tear direction. The tearing direction in the above configuration is the direction of the break line where the perforations are formed intermittently, that is, the direction in which the physical strength of the sheet member is reduced by forming the perforations penetrating the base layer. However, when the base layer is torn (ruptured) in the direction, for example, the paper layer is likely to delaminate between the perforations and the tearing direction of the paper layer is likely to deviate from the direction of the break line. Even if it does, the paper layer is driven by the tear guide resin layer that is torn faithfully along the perforations, so that the tear direction of the paper layer is corrected to the direction of the break line.

That is, with this configuration, the conical surface forming wall is torn more faithfully along the breaking line.

The tear guide resin layer is made of, for example, polyester or polypropylene.

In the configuration of the sheet member, the base layer may further include a print layer for providing a desired pattern to the packaging container between the paper layer and the tear guide resin layer. In this configuration, the tear guide resin layer is formed from a transparent resin layer. In this configuration, the tear guiding resin layer forms a layer on the outer surface side of the packaging container.

In the configuration of the sheet member, the sheet member preferably further includes a sealing layer laminated on the entire surface of the base layer on the paper layer side.

According to this configuration, the perforation penetrating the base layer is sealed by the sealing layer, and the inside of the container is more securely sealed from the outside of the container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a conical packaging container 10 according to the present embodiment, in which a conical ice cream 100 is stored inside. This conical packaging container 10 is made of a conical ice cream 100.
Lower half 12 of the container so that the top side of the conical shape of
Is held with one hand, the upper half 14 of the container is torn off and removed with the other hand, so that the upper half of the ice cream 100 can be exposed and eaten.

As shown in FIG. 2, the conical packaging container 10 is made of a fan-shaped blank 20 made of a sheet member.

That is, as shown in the drawing, the blank 20 is located substantially at the center of the blank 20 in the height direction, that is, between the fan-shaped apex 26 of the blank 20 and the outer edge 30 of an arc centered on the apex 26. Blank 2 corresponding to approximately middle part
One side edge 28 is provided with a tearing tab 16 for circumferentially tearing the conical surface forming wall 24 which forms a conical surface when the blank 20 is formed as a packaging container. The blank 20 has a first tear line 18 connected to one end 34 of the tab 16 on the vertex 26 side.
And the other end 36 of the tab 16 located opposite the apex 26 with respect to the first breaking line 18, ie the cone of the packaging container when the blank 20 is formed as a packaging container. Of the tab 16 located on the side of the substantially flat portion 32
6, and a second tear line 22 connecting to the second and third lines, respectively. In this embodiment, the substantially flat portion 32 of the conical packaging container 10 has an irregular shape formed by radially assembling semi-finished packaging containers formed from the blanks 20 from three directions, as described later. It is formed as a part (see FIG. 1).

More specifically, as shown in the figure, the first tear line 18 is connected to the one end 34 of the tub 16 and has a substantially circular arc shape centered on the apex 26 of the blank 20. Are formed over the entire width. With this configuration, the packaging container 10 is removed from the blank 20.
Is formed, the first tear line 18 is provided continuously in the circumferential direction of the conical surface forming wall 24 about the central axis passing through the vertex 26 of the conical packaging container 10. Become.

On the other hand, the second tear line 22 is
Is connected to the other end 36 of the blank 20 and is formed in a part of the blank 20 in the width direction of the blank 20 in a substantially arc shape non-concentric with respect to the first tear line 18 centered on the apex 26 of the blank 20. . That is, as best shown in FIG. 2, the second tear line 22 corresponds to the tear direction of the tab 16 (the direction corresponding to the direction of the arrow "A" in FIG. 1). When the packaging container 10 is made from the blank 20 and the packaging container 10 is made from the blank 20, an end point 38 is formed below the vicinity of the upper end of the conical surface of the conical ice cream 100 stored inside the packaging container 10. It is formed to be located. That is, when the packaging container 10 is made from the blank 20, the second tear line 22 is connected to the other end 36 of the tab 16 which is the starting point of the second tear line 22, as shown in FIG. , The second
The end point 38 of the tear line 22 is formed as a discontinuous tear line provided at different positions.

As shown in the figure, four V-shaped notches 40 are formed at predetermined positions on the other side edge 42 of the blank 20. For example, when the tab 16 is pulled, the tab 16 is inadvertently inserted. In the case of cutting in the middle, the other side edge 42
Conical surface forming wall 2 between a pair of adjacent V-shaped notches 40 on the side
4 is pulled in a direction opposite to the tearing direction “A” of the tab 16 so that the upper half 14 of the packaging container 10 is pulled.
Can be easily separated from the lower half 12.

The first and second tear lines 18,
Reference numeral 22 denotes a conical surface forming wall 24, as described later.
4 is formed from intermittently formed half-cut notches that do not penetrate in the thickness direction. FIG. 4 is an enlarged plan view of some of the cuts.

That is, as shown in the figure, each cut 44 is connected to a baseline 46 extending in the tearing direction “A” and to a tearing start point (that is, one end where tearing starts) 48 of the baseline 46. The auxiliary line portion 50 is inclined at an obtuse angle θ in a direction opposite to the tearing direction “A” with respect to the base line portion 46.

As shown in FIG. 5, the sheet member 66 (24) forming the conical packaging container 10 is
First, the conical surface forming wall 24 is connected to the first and second tear lines 18,
A transparent polyester layer 52 as a tear-guiding resin layer for allowing the polyester layer 52 to be faithfully torn along the polyester layer 52;
Printing layer 54 formed as a back-printing layer, an adhesive layer (dry laminate layer) 56, and water-resistant paper (rainguard paper)
, A paper layer 58 for securing shape retention of the sheet member 66 (24), an anchor coat layer 60, and a first polyethylene layer 62 in this order, and at least a polyester layer of the laminate. The cut 44 is formed so as to penetrate from the paper layer 52 to the paper layer 58, and then a second polyethylene layer 64 as a sealing layer for sealing the inside of the packaging container is heat-sealed over the entire surface of the first polyethylene layer 62. It is formed by this. That is, the cut formed in the sheet member 66 (24), and therefore, the cut 44 formed in the conical surface forming wall 24 constituting the packaging container 10 does not penetrate in the thickness direction of the sheet member 66 (24). It is formed as a half cut line.

In this laminated structure, the polyester layer 5
2 is a layer located outside the packaging container 10, while the second polyethylene layer 64 is a layer located inside the packaging container 10. In this laminated structure, the polyester layer 52, the printing layer 54, the adhesive layer 56, and the paper layer 58 constitute a base layer 65 of the sheet member 66. The second polyethylene layer 64 also functions as a heat seal layer as described below.

The sheet member 6 having such a laminated structure
The blank 20 made of 6 is formed as the conical packaging container 10 that stores the conical ice cream 100 inside as follows.

FIG. 2 is a plan view showing the blank 20 in a state where the polyester layer 52 located outside the packaging container 10 is facing up. From this state, the blank is first formed into a conical shape such that the polyester layer 52 is on the outside, that is, the second polyethylene layer 64 is on the inside, and the blank 2 is formed.
The part of the conical surface forming wall 24 on the one side edge 28 side of the blank 20 and the part of the conical surface forming wall 24 on the other side edge 42 side of the blank 20 are connected to the one side edge 28 side of the blank 20. The second polyethylene layer 64 and the polyester layer 52 on the other side edge 42 side of the blank 20 are overlapped so as to overlap each other.

Next, the overlapping side edges 28,
42, except for the portion corresponding to the tab 16, both sides are sealed by applying a hot melt (that is, the second polyethylene layer 64 and the polyester layer 52).
Are adhered to each other by hot melt) to form a conical semi-finished packaging container 68 as shown in FIG. The heat-sealed portions on both side edges overlapped with each other are indicated by dashed lines 51 in FIGS.

Next, the conical ice cream 100 is stored inside the semi-finished container 68 from the opening 70 side of the semi-finished container 68, that is, from the opening side of the conical flat portion of the semi-finished container 68.

Next, the opening 70 of the semi-finished container 68
A part of the blanks 20 forming the sides are radially brought together from three directions, and the inner surfaces of the blanks 20 facing each other, that is, the second polyethylene layers 64 are adhered to each other by heat sealing with a hot plate to form a conical package. Container 10 is completed. In this step, considerable tension acts on the sheet member 66 on the side of the substantially flat portion 32 of the packaging container with the upper end of the conical surface of the conical ice cream 100 as a fulcrum. However, the end point 38 of the second tear line 22 is located on the side of the conical surface forming wall 24 of the conical packaging container, that is, the second tear line 22 is located on the side of the substantially flat portion 32 of the packaging container. In this step, the possibility that the second tear line 22 breaks carelessly in this step is effectively reduced.

Now, the conical packaging container 10 containing the conical ice cream 100 inside as described above.
Is opened as follows.

That is, for example, while holding the lower half 12 of the packaging container 10 with one hand, the tab 16 is moved with the other hand in a direction substantially transverse to the container body, that is, the circle of the conical surface forming wall 24. When it is pulled in the circumferential direction, the conical surface forming wall 2
4 is simultaneously torn along the first tear line 18 and the second tear line 22, respectively, as shown in FIG. The end point 38 of the second tear line 22 is provided below and near the upper end of the conical surface of the ice cream 34. For example, the conical surface forming wall 24 is further forced beyond the end point 38 of the second tear line 22. When the ice cream 100 is torn, a part of the upper end of the conical surface of the ice cream 100 starts to be exposed to the outside, and the upper half 14 of the packaging container 10
This triggers release from the upper end of the 0 conical surface. When the conical surface forming wall 24 is further torn from this state, the opening diameter including the second tear line 22 of the upper half 14 of the packaging container 10 becomes conical ice cream 100.
Is larger than the outer diameter of the upper end of the conical surface of the ice cream 100, and the upper half 14 of the packaging container 10 is released from the upper end of the conical surface of the ice cream 100. At the same time, the conical surface forming wall 24 is torn circumferentially along the first tear line 18, and the first tear line 18 moves the conical forming wall 24 along the circumference. Since it is formed so as to make one round, the upper half 14 and the lower half 12 of the packaging container 10 are completely separated from each other when the tearing portion makes one round in the circumferential direction around the conical surface forming wall 24. .

Therefore, in the conical packaging container of the present embodiment, the upper half of the packaging container 10 can be touched with one touch only by pulling the tearing tab 16 substantially in the horizontal circumferential direction with respect to the main body of the packaging container 10. 14 can be removed from the lower half 12.

The first tear line 18 is formed on the tab 16
Of the conical surface forming wall 24 is provided substantially in the circumferential direction about the center axis passing through the vertex 26 of the container body with one end 34 as a starting point, so that the conical surface forming wall 24 is pulled by pulling the tab 16. By tearing along the entire circumference of the first tear line 18, the conical ice cream 100 stored in the packaging container is uniformly exposed over the entire conical surface. That is, in a state where the ice cream 100 is stored in the lower half 12 of the packaging container, the upper half 1 of the ice cream 100 is held by holding the packaging container with one hand.
When eating 4, the lower half 12 of the packaging container is not in the way.

As described above, the polyester layer 52, which is one forming layer of the sheet member 66, is formed so that the sheet member 66, and thus the conical surface forming wall 24, extends along the first and second tear lines 18, 22, as described above. It is provided as a tear-guiding resin layer that can be torn faithfully. That is, when the sheet member 66 is torn along the first and second tear lines 18 and 22, the polyester layer 52 includes all the layers 54, 56 and 58 other than the polyester layer 52 constituting the sheet member 66. , 60,
The sheet member 66 has a function of leading (inducing) the tearing of the entire sheet member 66, that is, a function of guiding the tearing of the sheet member 66. By this function, for example, even when the paper layer 58 undergoes in-layer peeling at the time of the tearing and the tearing direction of the paper layer 58 is randomized and the paper layer 58 tends to deviate from the direction of the first and second tear lines 18 and 22. As a result, the paper layer 58 is torn by following the polyester layer 52, and as a result, the tear direction of the paper layer 58 is the first,
The sheet member 66 is corrected in the direction of the second tear lines 18, 22 as a whole.
Is faithfully torn along.

As described above, a part of the conical surface forming wall 24 on the one side edge 28 side of the blank 20 and a part of the conical surface forming wall 24 on the other side edge 42 side of the blank 20 are as described above. Except for the portion corresponding to the tab 16, a part thereof is heat-sealed to each other. That is, the tab 16 is
0 is not adhered or fixed to the conical surface forming wall 24 on the other side edge 42 side. For example, when the tab 16 is pulled, an excessive force acts to break or cut the tab 16. , Is effectively eliminated.

The first and second tear lines 18, 22
Are formed from a plurality of cuts 44 as shown in FIG. 4 as described above. According to this configuration, for example, with respect to the tearing direction of the conical surface forming wall 24, that is, the tearing direction “A” of the sheet member 66, at the time of the tearing, the end point 72 of the specific baseline 46 and the next baseline are determined. 4
6, even if the leading end 76 of the tear 74 advancing from the end point 72 of the base line 46 deviates from the tear starting point 48 of the next base line 46, the leading end 76 of the tear 74 is By reaching the auxiliary line portion 50 of the notch 44, the traveling direction of the tear 74 is changed to the base line portion 4 connected to the auxiliary line portion 50 by the auxiliary line portion 50.
6 is guided and corrected in the direction of the starting point 48. Therefore, the configuration of the notch 44 allows the conical surface forming wall 24 to be formed.
Are more faithfully torn along the first and second tear lines 18,22.

As described above, the sheet member 66 (2
4), the second polyethylene layer 64 is laminated over the entire surface of the first polyethylene layer 62 where the first and second tear lines 18 and 22 are formed. With this configuration, the inside of the packaging container is effectively sealed from the outside.

As described above, the sheet member 66 does not include the aluminum layer. Therefore, for example, even if the inspection line is used in a food inspection for detecting whether or not metal pieces are mixed in the ice cream after packaging the ice cream and the inspection line does not transmit aluminum, the sheet member 6 may be used.
6, the degree of freedom in selecting the type of inspection line can be increased by the configuration of the present embodiment.

However, it is of course possible to use a sheet member including an aluminum layer as described below as a sheet member according to a modification of the above embodiment. Food inspection to detect whether metal pieces are mixed in the ice cream, for example, irradiating the ice cream with a test line including a test line that does not transmit aluminum before packing the ice cream, or packaging the ice cream After that, the test is performed by irradiating an ice cream with an inspection line that passes through aluminum.

That is, as shown in FIG. 6, a sheet member 90 according to this modified embodiment is obtained by laminating a print layer 78 on an aluminum layer 80 and bonding it to an adhesive layer (wet laminate layer) 82.
Is formed by laminating a polyethylene layer 86 over the entire exposed surface side of the paper layer 84 after forming a cut 88 in the laminate thus formed. Is done.

In this laminated structure, the printing layer 78 is a layer located outside the packaging container, while the polyethylene layer 86 is a layer located inside the packaging container. The polyethylene layer 86 not only functions as a heat seal layer, but also laminates over the entire surface of the paper layer 84, like the first and second polyethylene layers 62 and 64 of the sheet member 66 according to the above embodiment. It has the function of sealing the inside of the packaging container from the outside.

In the above embodiment, each of the cuts 44,
Each of the cutouts 88 is formed as a cut having a curved shape composed of the base line portion 46 and the auxiliary line portion 50. However, the shapes of the cutouts 44 and 88 are not limited to the curved shape. It may have a linear shape, a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially square shape, or the like.

In the above embodiment, the cuts 44 forming the first and second tear lines 18 and 22 are:
Although it is formed as a half cut which does not penetrate the sheet member 66, and thus the conical surface forming wall 24, for example, the second polyethylene layer 64 as a sealing layer, which is one forming layer of the sheet member 66 (24), is omitted. The cuts forming the first and second tear lines 18 and 22 are formed by the sheet members 66 and
Therefore, it can be formed as a through hole penetrating the conical surface forming wall 24, that is, a perforation. However, the second polyethylene layer 64 is preferably not omitted from the viewpoint of more securely sealing the ice cream in the container from the outside.

In the above embodiment, the tear guide resin layer 52 is made of polyester.
Instead of the polyester layer 52, a polypropylene layer formed of polypropylene can be used.

In the above embodiment, the second tear line 22 is formed in a part of the blank 20 in the width direction (that is, in the width direction of one side edge 28 and the other side edge 42 of the blank 20). However, the second tear line is the second tear line.
May be formed over the entire width of the blank 20 such that the end point of the tear line is located on the other side edge 42 of the blank 20. In this case, the end point of the second tear line is provided below the blank 20 in the vicinity of the upper end of the conical surface of the conical ice cream 100.

In the above embodiment, the food stored inside the conical packaging container is a conical ice cream, but the food packaged in the conical packaging container is a conical ice cream. There is no limitation, and it goes without saying that other foods such as chocolate confectionery may be used.
