Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is characterized in that a pair of left and right lids are provided with hinge parts on both left and right outer edges of a pack body formed of a thin synthetic resin sheet. The present invention relates to a packaging container such as an egg carton container, which is connected integrally through a lid, and each of the storage sections in the pack body can be individually covered with each lid.

[Conventional technology]

Conventional packaging containers such as egg cartons have a flange on one side edge of the pack body made of a thin synthetic resin sheet.
It is a so-called single-open type in which a lid with a flange is integrally connected to the pack body via a bendable hinge, and after putting the contents into the pack body,
Covering this with a lid connected via the hinge, and partially fixing the flange of the pack body and the flange of the lid with staples at the opposite side of the hinge, or
It is well known that the seal is fixed and sealed by partial heat fusion.

[Problem that the invention seeks to solve]

In this way, since the sealing means such as stapler or heat sealing is applied near the outer edge of the packaging container, that is, at the joint of the flange of the pack body and the flange of the lid that protrude outward on the opposite side from the hinge, In the sealed state, objects from the outside are likely to collide with or get caught on both flange portions exposed to the outside of the container over a long range, and external force acts directly on the sealed portion, making it easy for the container to open accidentally.

Furthermore, in recent years in the retail industry, in order to optimize product inventory and save labor on sales floor operations, the so-called PO3 (point of sales) system uses computers to centrally manage products. Product name, size,
It is common practice to attach barcodes that encode prices and other information using the width and spacing of lines.

In order to attach this barcode to a package, a flat surface is required over an appropriate length range, especially for containers such as packaging containers for eggs, which have many uneven curved surfaces on the bank body and lid. There was a problem in that it was difficult to form the bar code and the bar code could not be attached.

Furthermore, in the case of a so-called single-opening lid, when the seal is broken and the lid is opened, the entire upper surface of the bank body is opened, and the upper surface of the contents is entirely exposed.

Therefore, when there is a large amount of contents contained in the pack body, it is not possible to take out only a portion of the contents and keep the other portions sealed.

The present invention provides a packaging container in which a pair of lids are provided on both left and right outer edges of a bank body, and the flange portions of the side lids are formed in the middle of the left and right sides of the bank body, and are overlapped with a flat part of an appropriate width. The above problem is solved by sealing it.

Means for Solving Problem C] In other words, one of the gist of the invention of the present application is to provide a pack body formed of a thin sheet made of synthetic resin with contents on both left and right sides with a flat part of an appropriate width in between. A bendable hinge part that forms a recessed storage part for storing things, and a pair of lids that cover the left and right storage parts, respectively, are formed in parallel with the flat part on both left and right outer edges of the pack body. The right and left lids are integrally formed with flanges for sealing against the flat portions of the pack body on the edges opposite to the respective hinge portions, and The gist of the invention is that, in the invention, a tape having a pressure-sensitive adhesive attached to the upper surface of the flat part of the pack body is formed on the edges of the left and right lids opposite to each of the hinge parts. Each flange is locked and sealed.

[Operation and effect of the invention]

The invention of the present application has the above structure, so that in the wave-shaped state, the hinge portions that firmly connect the lid body and the pack body are located at the left and right outer edges of the bank body, and each flange on the left and right lid bodies overlaps the flat part located midway between the left and right parts of the bank body, making it difficult for both flanges to come into contact with anything else outside the container in the covered state, and the sealing part between the flat part and both flanges is careless. It doesn't come off. Therefore, when the container containing the contents is transported or distributed, accidents such as the lid opening and the contents being scattered do not occur.

Since the flat part can be formed over a considerable range, such as approximately the same length as the bank main body, it is also possible to print a bar code for the POS system on the flat part in advance, facilitating product management. .

If the flanges of both the left and right lids are overlapped on the upper surface of the flat portion, the back surfaces of the respective flanges and the upper surface of the flat portion will face in the same direction, so heat-sealing,
Appropriate sealing means such as a stapler can be applied, and the seal can also be easily sealed by pasting a tape coated with a pressure-sensitive adhesive on one side. In this case, it is possible to use a tape with a bar code for the POS system printed in advance on the top surface (the surface opposite to the surface coated with the pressure-sensitive adhesive) or printed after pasting, or the color of the tape can be changed. By changing the size of the product, it is possible to easily distinguish the size of the product.

Moreover, if the sealing means is a tape coated with a pressure-sensitive adhesive on one side, when opening the package, it is only necessary to peel off the tape from the flange. Since there is no momentum when the stapled or heat-sealed part breaks, which occurs when the container is peeled off by pulling it in the direction of separation, the container can be opened safely and easily without falling over.

Furthermore, the storage compartments located on both the left and right sides separated by the flat part of the pack body can be covered separately with each lid body,
Since the lid can be opened separately for each lid, it is possible to open only the necessary storage parts, which is extremely convenient when dispensing contents.

〔Example〕

The present invention will be described below with reference to drawings of embodiments. In the drawings, 1 is a bag container for chicken 14 vacuum-formed from a thin sheet of synthetic resin such as vinyl chloride resin or styrene resin, and the container 1 is a pack body 2. and a pair of left and right lids 3.3 integrally connected to the left and right inner and outer edges of the pack main body 2 via bendable hinge parts 4.4, respectively, and the pack main body 2 has the hinge parts 4.4. Each body 3 is provided with a flange 6 extending substantially horizontally outward in a direction perpendicular to the hinge part 4;
A sealing flange 7 is provided which projects substantially horizontally outward in a parallel direction along the opposite edge.

A flat part 8 of an appropriate width is integrally formed in the middle of the pack body 2 in parallel with the hinge part 4 so as to extend to the flange 5.

In addition, in the pack body 2, on both left and right sides of the flat portion 8, storage portions 10 having a substantially truncated pyramidal cylinder shape and capable of storing the lower body of the chicken egg 9, which is the content, are bulged out in a row at appropriate intervals. Shape. Each of the lids 3, 3 covers each row of left and right storage sections 10.10 divided by the flat portion 8. Therefore, each lid 3 covers the one row of storage sections 10. A storage part 11 having a substantially truncated pyramidal cylinder shape capable of storing the upper body of a chicken egg in a substantially symmetrical manner is bulged.

The width dimension (hl) of the flat portion 8 is equal to the width dimension (hl) of the flange 7, which is long in the direction parallel to the hinge portion 4 of each lid 3°3.
h2), and therefore the flat part 8
The flat part 8 is located between the side edges of both flanges 7゜7 stacked on the top surface.
A portion of the upper surface is exposed, and the cross section of the flat portion 8 is arranged so that the exposed portion is approximately on the same plane as the back surface when both flanges 7.7 are overlapped.
It is formed in a stepped shape, with the side adjacent to 0 being lower and the center being higher (see FIGS. 3 and 5).

The flat portion 8 has a plurality of rib portions 12, 12 appropriately spaced apart in the longitudinal direction thereof, which are formed to bulge downward so as to communicate with the left and right storage portions 10, 10.
It serves to increase the rigidity of the flat portion 8.

Further, in this embodiment, a cutout recess 13 is formed by cutting the front and rear edges of the flat portion 8 into a substantially trapezoidal shape in plan view.

Reference numeral 14 denotes a synthetic resin tape coated with a layer of pressure-sensitive adhesive 15 on one side. When the flanges 7.7 of both the cup bodies 3, 3 are overlapped on the upper surface of the flat part 8, the paste is applied across the back surface of the side flange 7.7 and the upper surface of the flat part 8. It is to be sealed. In the embodiment shown in FIG. 4, the ends of the tape 14 are extended beyond the front and rear notches 1313 of the flat part 8 to the vicinity of the front and rear flanges 6.6 of the lid body 3. The end portion of 14 is configured so that it can be easily picked up with fingers.

Note that reference numerals 16 and 16' designate ventilation passages that are recessed in both flanges 5.6 and communicate with the storage portion 10.11.

In this configuration, each storage section 10 in the pack body 2
．． Put chicken egg 9 into 10, then insert hinge part 4.4 on both left and right sides.
When the right and left lids 3.3 are bent at certain points and cover the left and right rows of eggs 9, respectively, the flanges 7. of the lids 3.
7 flat surface of pack body 2 80 stepped lower part 8
It is supported in contact with the upper surface of b.

In this state, a pressure sensitive adhesive 15 is applied across the back surfaces of both flanges 7.7 and the upper surface of the stepped upper portion 8a of the flat portion 8.
When the applied tape 14 is arranged and adhered, the container 1 is easily sealed.

Since the sealed area is located approximately at the center of the container 1, when displaying or transporting the container 1,
There are fewer opportunities for the sealed area to come into contact with other things,
Therefore, there is no danger of the seal being accidentally removed.

To open the container 1 sealed in this way,
While pressing one side of the lid 3 from above, apply the tape 14.
The tape 14 can be peeled off from the flange 7 and the flat part 8 by turning up one end and pulling it. At this time, there is no momentum when the stapled or heat-sealed part breaks like in the past. , the container can be opened without tipping over.

Since the ends of the tape 14 extend outward from the notch recesses 13 at the front and rear ends of the pack body 2, the extended portions become the gripping pieces of the tape 14, and the tape 14
can be easily peeled off. In this case, the exposed portion of the pressure-sensitive adhesive 15 on one side of the extended tape 14 may be folded back to form a tab portion so as not to adhere to the edge of an adjacent container. At this time, a portion of the folded portion may be stuck to the back surface of the flange 7 of the lid body 3 or the flat portion 8 of the pack body 2, which is a so-called sandwiching state.

Note that if a barcode 17 as shown in FIG. 4 is printed on the top surface of the tape 14 in advance, product management in the POS system can be easily performed.

Furthermore, the color of the tape 14 can be changed depending on the size of the egg.
When folded, the sealed containers 1 can be easily distinguished by coloring them such as LL egg cartons are colored red, L egg cartons are colored, M cartons are colored green, etc.

FIG. 7 shows a separate flat portion 8 for each flange 7.7.
The tapes 14', 14' are attached to the
An example of parallel arrangement in rows is shown. According to this example,
For example, if you want to open only the right side lid 3, you only need to peel off the right side tape 14';
Since the left tape 14' is firmly attached to the back surface of the flange 7 and the upper surface of the flat portion 8 of the left lid body 3 regardless of the peeling off, the egg can be partially removed. Even if a locking and sealing means such as heat sealing or a stapler is used instead of the tapes 14' and 14', each lid 3
, the lid can be opened every 3 seconds.

In each of the embodiments described above, the length of the tape 14, 14' may be shortened so that the tape 14, 14' is partially attached in the longitudinal direction of the flange 7.

In each of the embodiments described above, the longitudinal edge of the flange 7 (the edge along the longitudinal direction of the flat part 8) of each lid body 3 was approximately linear, but as shown by the dashed line in FIG. By forming a notch 18 in which one or both side edges of the flanges 7.7 are cut out in an arbitrary shape such as a triangular or rectangular shape in plan view, the longitudinal edges of both the flanges 7.7 can be aligned with each other. Even when the flat portion 8 is supported in close proximity to the upper surface of the flat portion 8, the exposed portion of the upper surface of the flat portion 8 has a partially large area. It is also possible to increase the wearing force.

8 to 10 show still another embodiment of the locking and sealing means between the flange 7 of each lid 3 and the flat part 8 of the pack body, in which the flat part 8 is recessed downward at a plurality of appropriate locations. While the locking portions 19 are bulged, the side edges of each flange 7 can be engaged with and disengaged from the respective fitting locking portions 19 . The fitting and engaging portion 20, which is generally trapezoidal in plan view, is formed to bulge downward.

According to this, when sealing the lid, by simply pushing the fitting portion 20 on the flange 7 of each lid body 3 into the fitting locking portion 19 on the flat portion of the pack body from above, the elastic deformation of both can be resisted. It can be fitted and locked and sealed. Since the fitting/locking part 19 and the fitting/engaging part 20 are each formed by bulge molding, the flat part 8 of the flat thin sheet and the flange 7 (role of so-called reinforcing ribs to reduce eroding deformation) are formed. can also be fulfilled.

In addition, the flanges 7°7 and bar on both the left and right lids 3.3
The means for sealing the flat portion 8 of the hook body 2 may be replaced by a tape coated with a pressure-sensitive adhesive as described above, and may be replaced by a stapler or heat fusion.

In addition, the contents to be stored in the packaging container 1 are not limited to chicken eggs, but can also be applied to confectionery such as steamed buns, and elongated products such as yokan. 10.11.11 may be bulged into any shape such as a hemisphere or an elongated semi-cylindrical shape depending on the shape of the product.

Therefore, although the pack body 2 has a bulging storage portion, each lid 3 may be formed into a flat plate shape with no bulging storage portion.

Furthermore, the rows of storage parts 10 formed on both the left and right sides of the flat part 8 in the bag body 2 can be made into multiple rows, such as one row or two rows, respectively. Any number of different asymmetries can be used.
