Description

[Detailed Description of the Invention] The present invention relates to an improvement in a container which is particularly effective for packaging ice cream, and whose body wall can be peeled off as the contents decrease.

Conventionally, this type of container has only been provided with perforations on the body wall for tearing off, and no preparation has been made at the starting point for tearing off.

Normally, the plucking starting part is provided at the joint of the blanks that make up the container, but in the past, the plucking was done by peeling off the upper end from the lower one at this joint using a nail. Collection is being carried out.

The present invention has been devised so that a trigger for plucking can be easily obtained without requiring the above-mentioned troublesome effort.

Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 and 2 show the first embodiment of the present invention.
The present invention is applied to a cup-shaped container.

In the figure, a trunk wall blank 10 is provided with cut-off perforations 12 so that when the blank is rolled up and the side edges are glued together, the trunk wall can be cut off spirally from the top to the bottom.

In this case, the lateral perforations 14 are approximately L-shaped with respect to the tearing direction.

This perforation shape is particularly effective when the blank 10 is made of paper.

This is because the low grain usually runs in the longitudinal direction of the blank, almost perpendicular to the tearing direction, so if each perforation 14 is formed with a part that intersects the low grain direction at an acute angle, each perforation This is because the breaks between the 14 points occur smoothly and continuously.

Further, the upper part of the blank 10 is provided with a forming part 1 of the curl part 15.
6 is provided, and an engaging portion 18 with the bottom plate 17 is provided at the lower part.

Dashed lines 20 and 22 indicate broken lines. Furthermore, blank 10
A cutting perforation 24 is provided on the upper part of the blank, which becomes a ring when the blank is wound, and this cutting perforation 24
A knob piece 26 and a cutting piece 28 are formed between the starting end of the spiral cutting perforation 12 and the starting end of the spiral cutting perforation 12.

These tab pieces 26 and cutting pieces 28 are the side edges of the blank to be glued and should be provided so as to overlap with the cutting start part, and if the cutting perforations 24 forming the ring are not provided, , is provided at the top between the perforations 12 at the side edges.

The tab piece 26 is formed on the upper side edge and is attached to the cutting piece 2.
8 is formed on the lower side edge.

The knob piece 26 is formed, for example, by providing a pair of notches 30 at the edge of the upper side edge.

Further, the knob piece 26 may be sandwiched between the notches 30 and protrude outward from the edges of the side edges.

On the other hand, the cutout piece 28 is preferably smaller than the tab piece 26, protrudes outward from within the adhesive portion 32 to prevent the cut line 34 from being blocked by the adhesive, and extends beyond the cutout perforation. is formed as close as possible to

Note that the cut line 34 may be a continuous line perforated.

In addition, a notch 36 is provided at the edge opposite to the cutout piece 28 with a width larger than the width of the cutout piece 28 in order to facilitate removal of the cutout piece.

Note that this notch 36 may not be provided and the cut line 34 of the cut piece may be extended near the edge.

Additionally, reference numerals 38 and 40 in the figure indicate notches, which are provided to facilitate communication between the perforations 12 and 24 when they are continuously broken.

Next, FIGS. 3 and 4 show another embodiment of the present invention.

In this example, the present invention is applied to a cone-shaped container.

In the figure, the blank 42 is rolled up and the side edges are glued together to form a cone shape, and a cutting perforation 44 is cut out so that the body wall can be cut out in a spiral shape from the top to the bottom. .

There is also a perforation 46 forming a ring at the bottom.

In this case, the perforations 44 and 46 are set as broken lines extending in the tearing direction.

Of course, the shape of the perforation may be a dovetail shape as in the previous embodiment.

Further, a forming portion 50 of the curl portion 48 is preferably provided at the upper part of the blank.

Furthermore, the tab piece 52 and the cutting piece 54' blank 42
The side edge portion to be bonded is provided so as to overlap the cutting start portion.

In this case, the cutting start portion is set at the top of the side edge portion between the perforations 44.

However, if a perforation (not shown) is provided at the top of the blank 42 to form a ring when it is wound, the cutting start portion will be
It is set between this perforation and the starting end of the spiral cutting perforation 44.

The tab piece 52 is formed on the upper side edge, and the cutout piece 44
is formed on the lower side edge so as to extend from inside to outside of the adhesive part 45.

These pieces 52, 54 are made wider than in the previous embodiment.

Also in this case, a notch 56 wider than the cutout piece 54 is provided at the edge portion facing the cutout piece 54.

However, this notch 56 may not be provided, and the cut line 58 of the cut piece 54 may be extended longer on the edge side.

In addition, in the figure, 60 is a notch, 62 is a small hole,
These overlaps create perforations 4 at the joints of the blanks.
This is to allow smooth communication of the 4.46 break.

They are also particularly effective if the perforations become misaligned at the joints during the assembly of the container.

In addition, in order to prevent the contents from leaking depending on the nature of the contents, regardless of the container of any of the examples, after the container is assembled or in a blank state, the entire inner wall or the perforations and notches are covered. It is desirable to apply wax or the like.

Since the present invention has the above configuration, it operates as follows.

That is, in the case of the first embodiment (FIG. 2), when eating the ice cream etc. filled in the container, the knob piece 26 that is not glued and is lifted from the body wall.
By pulling with your fingers, you can easily open the torso wall.

At this time, at the same time as folding up the tab piece 26, the cutting piece 28
is also folded up, and at the same time the upper and lower perforation lines 24.12 are broken, the gap between the cutting piece 28 and the notch 36 is also broken.

Then, as the contents decrease, the perforation line 12.24
The spiral stripes are continuously ripped out along the .

Further, in this case, the curled portion 15 at the top of the container is cut off during the initial plucking.

On the other hand, even in the case of the second embodiment (FIG. 4), the tab piece 52 is folded up together with the cutout piece 54, and the starting end of the perforation line 44 is broken and the cutout piece 5
4 resections are made at the same time, leading to a single-walled section that can be easily plucked out in the subsequent section.

In this case, the curled portion 48 of the container remains attached to the spiral strip.

As described above, in the present invention, a special feature has been added to the cutting start part, so that it is possible to start plucking smoothly without the hassle of starting cutting unlike in the past.

Therefore, when the contents are ice cream or the like and the target audience is young children, the container can be very easy to handle.
