Abstract

PURPOSE:To obtain a multi-pack unit which can be easily separated to each pack and surely peeled off from the cover. CONSTITUTION:A reinforcing film is laminated between a paper layer and a thermoplastic resin layer in a covering material 3 and perforations 4 for cutting off so as to cross the covering material 3 are provided at the connection area 39 of the covering material 3 where respective cups are connected with adjacent ones. In this way, a multi-pack unit 1 can be easily separated to each cup 2 with cover by the perforations 4. The covering material 3 can be peeled off from the cup 2 without exfoliation between paper layers in the covering material 3 due to the reinforcing layer thereof. Patterns are printed on the external face of paper layer by use of a heat-resistant UV ink and a heat- resistant OP varnish is applied thereon and decoration is applied on the covering material 3. Since steam generated from the paper layers on heat-sealing of the cover penetrates the pattern and the OP varnish, bubbling is prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-pack in which a plurality of cup containers filled with contents are put together and are connected by a lid made of paperboard for sale.

[0002]

2. Description of the Related Art Conventionally, dessert foods such as yogurt, pudding, and jelly are often formed into individual cup containers in consideration of ease of eating, and for convenience of bulk purchase. In addition, a so-called multi-pack in which a plurality of cup containers are placed on a mount and shrink-wrapped at one time is widely used. By the way, in the shrink-wrapped multi-pack, a step of separately forming a cup container and a lid material, a step of sealing the cup container and the lid material to form an individual cup container, and collecting these two or three pieces It is manufactured by the process of placing it on the mount and shrink wrapping process, so it takes time for the packaging work, and when it is discarded, not only the cup container but also the lid material, the mount, the shrink wrapping, and many other wastes. There was a problem that came out. Therefore, recently, a paperboard lid material sized to connect a plurality of cup containers is used,
A multi-pack in which a lid member is sealed and attached to the opening flange portion of each cup container filled with contents to simultaneously cover a plurality of cup containers with one lid member and to connect them to each other. Is proposed.

[0003]

However, the multi-pack in which a plurality of cup containers are connected by one lid as described in the prior art has the advantage that the packaging material can be reduced and the manufacturing efficiency is good. However, there is a problem in that it is difficult to separate them individually or to remove the lid member from the cup container. In particular, there is a problem that when the lid material is peeled from the flange portion of the cup container, the paper layer of the lid material causes interlayer peeling and cannot be peeled off.

The present invention has been made in view of the problems as described above, and its purpose is to make it easy to disassemble the individual containers, and to secure the lid member from the cup container after the disassembly. It is to provide a multi-pack that can be peeled off.

[0005]

In order to achieve the above object, the multi-pack of the present invention comprises a processed paper having at least an inner surface coated with a thermoplastic resin or an outward opening flange formed of the thermoplastic resin. And a plurality of cup containers each having an inner surface and a lid member made of a processed paper whose inner surface is coated with a thermoplastic resin, and an opening flange of each cup container in a state of connecting the plurality of cup containers. In a multi-pack obtained by heat-sealing the lid material on the inner surface side of the part, a reinforcing film layer is laminated between the paper layer and the thermoplastic resin layer in the lid material, and a portion for connecting each cup container and It is characterized in that a perforation for cutting that crosses the lid material is provided in the connecting region of the lid material.

When printing is performed on the outer surface of the lid material, a heat-resistant UV ink is used to print a pattern on the outer surface of the paper layer of the lid material, and the heat-resistant OP varnish is formed so as to cover the picture. Is printed on the entire surface.

[0007]

In the multi-pack of the present invention having the above-mentioned structure, the perforations provided in the connecting region of the lid function as a breaking portion when separating the multi-pack into individual cup containers with lids. Then, the reinforcing film layer laminated on the lid material serves to prevent delamination of the paper layer when the lid material is peeled from the flange portion of the cup container. In addition, when a pattern is printed on the outer surface of the lid material with heat-resistant UV ink, and a heat-resistant OP varnish is printed on the entire surface so as to cover the pattern and decoration is applied, when the lid material is heat-sealed. The occurrence of the bubbling phenomenon on the surface of the lid material is prevented.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a multi-pack as an embodiment of the present invention. As shown in FIG. 1, the multi-pack 1 has three cup containers 2 covered by one lid member 3. At the same time, it has a connected form.

The cup container 2 is a paper cup formed of a processed paper having at least an inner surface coated with a thermoplastic resin, or a cup-shaped molded article formed by molding a thermoplastic resin, and an outer portion of the cup container 2 is formed at an opening thereof. The one with an oriented flange is used. Examples of the processed paper forming the paper cup include those having a laminated structure of a thermoplastic resin layer / paper layer / thermoplastic resin layer, a thermoplastic resin layer / paper layer, etc. in order from the inner surface side, and a cup-shaped resin As a molded product,
Examples thereof include a single layer of thermoplastic resin and a multilayer of thermoplastic resin. Specific examples of the thermoplastic resin include polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonate, polyamide and polyester.

On the other hand, the lid member 3 is formed by punching out a processed paper whose inner surface is coated with a thermoplastic resin into a developed shape shown in FIG. 3. In this embodiment, the processed paper S having the layer structure shown in FIG. 2 is used. ing. That is, this processed paper S is a cup base paper (25
The adhesive layer 32 made of polyethylene (20 μm), the reinforcing film layer 33 made of polyethylene terephthalate film (12 μm), and the thermoplastic resin layer 34 made of polyethylene (40 μm) on the inner surface of the paper layer 31 made of 0 to 300 g / m ² ). In order to further decorate,
The pattern 35 is printed on the outer surface of the paper layer 31 with heat-resistant UV ink, and the heat-resistant OP varnish 36 is printed on the entire surface. A cup base paper with a coat layer may be used for the paper layer 31. Further, as the reinforcing film layer 33 laminated between the paper layer 31 and the thermoplastic resin layer 34, a nylon film, a high density polyethylene film or the like can be used in addition to the polyethylene terephthalate film.

A lid member 3 punched from the above-mentioned processed paper S
Has side wall regions 38 on both sides of the top surface region 37, as shown in the development view of FIG. This sidewall region 38
Is a portion for connecting each cup container 2 with the lid material 3 and then bending the lid as shown in FIG. 1 to give the multipack 1 strength. -Shaped perforated ruled line a and an arcuate notch b slightly larger than the flange portion of the cup container 2 are formed between the perforated ruled line a.

Further, the top surface region 37 and the side wall region 3 are provided in the connecting region 39 of the lid member which is a portion for connecting the cup containers 2.
A perforation 4 for cutting is provided over 8. Then, the right cut-out perforation 4 in the top surface area 37 is adjacent to the upper and lower perforation ruled lines a and has the arcuate overhanging portions 4a and 4b, and the left-side cut perforation 4 is above. Adjacent to the perforation ruled line a is provided so as to form one arc-shaped overhanging portion 4c, and these overhanging portions 4a, 4b, 4c seal the lid member 3 to the cup container 2. It is provided in the connecting area 39 of the top surface area 37 in such a size that it becomes the outside of the flange portion when it is formed. Further, the perforations 4 for cutting are coarsely provided in the top surface region 37 (for example, a cutting edge portion 5 mm and a connecting portion 2 mm) and finely provided in the side wall region 38 (for example, a cutting edge portion 2 m).
m, a connecting portion 2 mm), so that the top surface region 37 can be easily cut and the connection strength of the multipack 1 can be maintained. In this embodiment, the number of connecting portions in each of the overhanging portions 4a, 4b, 4c is 3
However, two or one may be used for easy cutting.

When manufacturing the above multi-pack 1, as shown in FIG. 4, a cup container 2 filled with contents.
Are arranged in one row, and the lid member 3 is placed so that the top surface region 37 covers the flange portion 21 of each cup container 2, and heat sealing is performed by a ring-shaped sealing head, or as necessary. According to the above, pre-sealing is performed by a flat plate-shaped seal head and then heat sealing is performed by a ring-shaped seal head. In this case, an arcuate cut b in the lid member 3
It is necessary to determine the interval between the cup containers 2 so that each is located slightly outside the outer circumference of the flange portion 21 of each cup container 2. 3 for this positioning
The cup container 2 may be held by a retainer having two circular holes to heat-seal the lid member 3. As a result, the lid member 3 is sealed along the flange portion 21 of each cup container 2 in a close contact state, and at the same time, the three cup containers 2 are connected. Thereafter, the side wall region 38 of the lid member 3 is bent inward along the perforation ruled line a, and the inner surface thereof is adhered to the upper side surface of each cup container 2 by a hot melt adhesive to obtain the multipack 1 shown in FIG. It is formed.

When the sealing material is heat-sealed by the seal head as described above, the water contained in the paper layer 31 of the processed paper S constituting the lid material 3 evaporates and tries to escape. Therefore, for example, when a film is laminated on the outer surface of the paper layer 31 of the processed paper S, the water vapor pushes up the film to cause a so-called bubbling phenomenon, which causes unevenness on the surface of the lid member 3. In the example, as described above, the heat-resistant UV ink is used to print the pattern 35 on the outer surface, and the heat-resistant OP varnish 36 is formed so as to cover the pattern 35.
Since the lid material 3 is formed of the processed paper S formed by printing the entire surface of the
The lid material 3 is heat-sealed while passing the ink pattern 35 and the OP varnish 36 and keeping the surface flat.

The above-mentioned multi-pack 1 may be sold as it is or may be sold in shrink wrap.
Then, at the time of opening after purchase, the cut-out perforations 4 of the lid member 3 are separated. When the multi-pack 1 is disassembled in this way, each cup container 2
A tab is formed at the end of the top surface region 37 of the lid member 3 attached to the top. That is, the right side cup container 2 has an overhanging portion 4b.
As a result, tabs are formed in the middle cup container 2 by the overhanging portion 4a and in the left cup container 2 by the overhanging portion 4c. Therefore, the lid member 3 can be peeled off from the cup container 2 by pinching the tab. Since the tab is provided in this manner, direction control is performed at the time of peeling, and it is possible to prevent the lid member 3 from being cut from the end portion of the arcuate cut b in the lid member 3. In addition, when the perforation 4 for cutting is provided straight and such a tab is not formed at the time of breaking, the peeling direction is instructed by printing or the like so that the lid material 3 is not cut from the end of the cut b. I need to put it. The reinforcing material layer 33 is formed on the lid member 3 as described above.
Are laminated, the paper layer 31 does not cause delamination when the lid material 3 is peeled from the flange portion 21 of the cup container 2, and the entire lid material 3 is neatly peeled from the flange portion 21 of the cup container 2. be able to.

The protruding portion forming the tab at the time of breaking as described above may be provided in a part of the perforation for cutting the lid material according to the number of cup containers to be connected. For example,
When the number of cup containers is two, as shown in FIG.
A perforation 4 for cutting is provided across the top surface region 37 and a side wall region 38 of the lid member 3 so as to cross the center of the lid member 3, and adjacent to the upper and lower perforation ruled lines a, the overhanging portions 4 are opposite to each other.
d and 4e may be formed on the perforation 4 for cutting in the top surface region 37. By forming the overhanging portions 4d and 4e in this manner, the multipack is cut out at the perforation 4
When ruptured, tabs are formed on both cup containers 2, respectively.

Further, in the case where two pieces are connected vertically and horizontally, a lid member 3 as shown in FIG. 6 may be used. This lid material 3
Is composed of a quadrangular top surface region 37 that covers four cup containers and four side wall regions 38 that are connected to each side around the quadrangular surface region. Each is a straight perforated ruled line a and two arcuate notches b
Is provided. Two cutting perforations 4 and 5 are provided in a cross shape across the top surface region 37 and the side wall region 38 so as to cross and cross the center of the lid member 3.
The vertical cutout perforations 4 in the top surface region 37 are adjacent to the upper and lower perforation ruled lines a and the overhanging portions 4 in the same direction.
f and 4g are formed, and the overhanging portion 4 opposite to these is formed.
It is provided so that h and 4i are formed in the vicinity of the perforation 5 for cutting in the lateral direction. In this way, the overhanging portion 4f
By forming 4i, tabs are respectively formed on the four cup containers 2 when the multipack is broken at the perforations 4 and 5 for cutting to be separated.

The lid member 3 shown in FIG. 7 is a modification of the lid member 3 shown in FIG. 3, in which the width of one side wall region 38 is increased, and the side wall region 38 intersects the perforation 4 for cutting. By providing a triangular cutout portion 38a at the end edge, the display effect is aimed at a storefront or the like. In addition, such a cutout portion 38a is provided with a positioning pin standing on a retainer used when the lid member 3 is heat-sealed, and the cutout portion 38a is engaged with this pin to position the lid member with respect to the cup container. It can also be used to do.

The lid member 3 shown in FIG. 8 is the same as that shown in FIG. 3 in that it has side wall regions 38 on both sides of the top surface region 37, but the portion where the side wall region 38 is bent is a perforated ruled line. It is formed only by a and does not have an arcuate cut b. That is, the distance between the upper and lower perforated ruled lines a is such that the flange portion of each cup container fits in. When three cup containers are connected by this lid material 3, the top surface region 3
A multipack of the type in which the boundary portion between 7 and the sidewall region 38 is straightened is formed. When the multi-pack using this lid material 3 is disassembled at the perforation 4 for cutting and the lid material 3 is peeled from the obtained cup container with the lid material, the lid material 3 is cut and peeled off from any direction. The cutting perforation 4 can be provided straight as shown in the drawing since it will not run out. Of course, the tab may be formed when the cutting perforation 4 is broken as described above.

Incidentally, in each of the above-mentioned lid materials,
It is preferable that the outermost cutting edge portion of the perforation for cutting off intersects with the edge of the side wall region. By doing so, the cutting edge portion at the outermost end serves as a notch, and the tearing of the perforation for cutting can be started more easily.

Further, regarding the lid material used in the multi-pack of the present invention, the side wall regions extending on both sides of the top surface region are taken into consideration in consideration of the bending strength of the material constituting the multi pack and the weight of the contents to be stored. It is also possible to omit one or both. Further, as described with reference to FIG. 7, the width of each side wall region may be changed by increasing the width of one side wall region to provide a display effect.

[0023]

As described above, the multi-pack of the present invention is provided with the perforation for cutting that crosses the lid member in the connecting region of the lid member which is a portion for connecting a plurality of cup containers. , It can be easily disassembled into individual cup containers with lids, and the reinforced film layer is laminated between the paper layer and the thermoplastic resin layer in the lid material to ensure that the lid material is removed from the cup container after disassembling. Can be peeled off.

Further, by using a cover material which is decorated by printing a design with a heat resistant UV ink on the outer surface of the paper layer and further printing a heat resistant OP varnish on the entire surface so as to cover the design. Since the occurrence of a bubbling phenomenon on the surface of the lid material is prevented during heat sealing of the lid material, it is possible to manufacture a multi-pack provided with the lid material whose surface remains flat.
