Description

[Detailed Description of the Invention] The present invention relates to an improvement of an assembled paper carton for packaging eggs, which is composed of a single sheet of horizontally long cardboard.

As a conventional assembled paper container of this type,
There is one shown in Publication No. 7.

The conventional paper carton divides a horizontally long cardboard body into a frame block piece that defines the outer frame of the box-like paper carton, and a holding block piece that is folded and stored inside the box-like paper carton and holds eggs, In addition, the frame block piece is provided with a top piece, a rear piece, a bottom piece, and a front piece that are successively connected to each other via a fold line, and a pair of left and right notches that are directly connected to the holding block piece via a fold line and have a plurality of facing notches are provided. Only two holding pieces are provided, and a pair of left and right holding pieces are provided inside the box-shaped paper carton defined by the frame block pieces.
It is folded into a letter shape and stored, and the eggs are held upright in the opposing notches of the pair of right and left holding pieces.

However, in such a conventional paper carton, a pair of left and right holding pieces provided on a holding block piece are directly connected via a fold line, and the pair of left and right holding pieces form a V-shaped egg holding space. Therefore, due to the necessity of maintaining the shape and positioning of the ■-shaped space, an insertion groove is formed on the fold line connecting the left and right pair of holding pieces, and the insertion groove is formed on the bottom piece of the other frame block piece. In addition to forming a rising support wall that fits into the frame block, a partition wall is required to regulate the positional relationship between the two V-shaped spaces, and the partition wall is removably formed in the frame block piece. As a result, not only is it complicated to process the frame block pieces and holding block pieces for a single sheet of horizontally long cardboard, but also the assembly work is unnecessarily complicated.Furthermore, the structure is complicated and the multiplication is very poor. .

Moreover, the configuration in which the egg is held in a V-shaped space formed by a pair of right and left holding pieces inevitably requires holding the egg in an upright position, so even if both sides of the egg are opposite the holding pieces. Even if the egg is supported by the notch, the egg is naturally in an unstable state where it tends to move upward, and it cannot be denied that the egg may hit its head and break during transportation.

In addition, conventional paper cartons have a buffer piece on the upper edge of the notch, but
The buffering action of the buffer piece also works to lift the egg upwards, and this also contributes to the unstable holding.

Further, the V-shaped holding space is held in shape by fitting the insertion groove into the upright support wall described above, and the egg is held more strongly between the left and right holding pieces on both sides using the holding force as a holding force. However, this clamping force is also a factor in pushing the upright egg upward.

The present invention was devised in view of the shortcomings of conventional paper containers, and aims to provide a new assembled paper container that is extremely easy to process, structure, and assemble, and that can hold eggs extremely stably. be.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment.As shown in FIG. A holding block piece Y that is folded and stored inside the box-shaped paper carton to hold eggs.

The frame block piece X is divided along the fold line e and the fold line
- Mounting piece 1 with locking part 11 connected sequentially via c-d
0, a top piece 2, a rear piece 3, a bottom piece 4, and a front piece 5, and an engaging part 13 that engages the locking part 11 of the piece 10 is formed on the front piece 5, and the other This is based on a structure in which a pair of left and right holding pieces 6 and 8 are provided on the holding block piece Y to form a space for holding eggs, and the feature lies in the following structure.

That is, as shown in the figure, the left holding piece 6 of the holding block piece Y
A fixing piece 7 is provided between the right side holding piece 8 and the left and right holding pieces 6 and 8 at an interval, and a fixing piece 7 is provided along a broken line f-g.
In the assembly work described later, by bending the pair of left and right holding pieces 6 and 8 along the fold line f-g with the fixing piece 7 as the upper side of the trapezoid, the inside of the box-shaped paper container that is restrained by the frame block piece In this structure, an inverted trapezoidal egg holding space 16 is formed.

In the embodiment, it is assumed that the left holding piece 6 of the pair of right and left holding pieces is connected to the front piece 5 of the frame block piece X via the fold line e.

In addition, a plurality of circular through holes 14 and 15 are formed facing each other at a constant interval in the pair of left and right holding pieces 6 and 8 forming the inverted trapezoidal egg holding space 16, respectively. By completely fitting both ends of the egg into the opposing feeding holes 14 and 15, the egg is held horizontally within the space 16.

Furthermore, a support piece 9 is provided on the free end side of the holding block piece Y, and is connected to the right side holding piece 8 via a fold line. It is configured to abut on the broken line portion of the piece 3 and the top piece 2 from the inside to support the inverted trapezoid of the holding space 16 while maintaining its shape.

Therefore, in the holding block piece Y of this embodiment, the fixing piece 7, the right holding piece 8, and the supporting piece 9 are successively connected from the left side holding piece 6 via the broken line fgh.

Also, tongue pieces 12 are cut into the substantially middle edges of both ends of the bottom piece 4 on the side of the frame block piece X, and the fixing pieces 7 are fixed to each tongue piece 12 with adhesive, staples, etc. , is configured to position and maintain the shape of the inverted trapezoid of the space 16.

Note that the top piece 2 and bottom piece 4 and the rear piece 3 and front piece 5 of the frame block piece It is set to be longer than the width and shorter than the width of the top piece 2.

Therefore, when assembling a box-shaped paper carton using the horizontally long cardboard body 1 having such a structure and packaging chicken eggs in the paper carton, first, as shown in FIGS. 2 to 5, the rear side of the frame block piece After bending the piece 3, the bottom piece 4, and the front piece 5 into a substantially U-shape along the fold line c-d, the left holding piece 6 is inclined downwardly inward toward the bottom piece 4 along the fold line e. Then, with the fixing piece 7 in between, bend the right side holding piece 8 to the bottom piece 4 via the fold line g.
If you bend it so that it slopes upward toward the rear piece 3,
The left and right pair of holding pieces 6 and 8 can easily form an inverted trapezoidal egg holding space 16 in which the fixing piece 7 in parallel contact with the bottom piece 4 is the upper side of the trapezoid.

Also, during the assembly process or at any other appropriate time, fix both ends of the fixing piece 7 in contact with the bottom piece 4 to the tongue pieces 12 formed on the bottom piece 4 with adhesive, staples, etc. wear it.

Particularly, in this case, just by fixing the fixing piece 7 together with the action of the supporting piece 9, the shape retention and positioning of the inverted trapezoidal space 16 can be achieved extremely easily and reliably.

Next, the chicken egg E is inserted horizontally into the inverted trapezoidal holding space 16 from the open top side, and the opposing through holes 14 and 8 of the pair of left and right holding pieces 6 and 8 that form the space 16 are 15, a chicken egg E is firmly gripped by the entire periphery of the through hole.
After completely fitting both ends of the support piece 9 connected to the right side holding piece 8 to the fold line part of the rear piece 3 and the top piece 2 by bending it through the fold line, At the same time as bending, the mounting piece 10 connected to the top piece 2 is further bent along the fold line a, so that the locking part 11 of the mounting piece 10 is engaged with the retaining part 13 of the front piece 5. For example, the assembly work of the paper carton and the packaging work of the eggs E are completed immediately.

Further, if perforations 17 are provided in the longitudinal direction of the cardboard body 1 as shown in the figure, it becomes possible to separate the chicken eggs E one by one in the above-mentioned packaged state.

As described above, the present invention divides a piece of horizontally long cardboard into a frame block piece that defines the outer frame of the box-like paper carton, and a holding block piece that is folded and stored inside the box-like paper carton to hold eggs. too,
This is characterized by the fact that the holding block piece is provided with a fixing piece that separates the left side holding piece and the right side holding piece with a space between them, so the presence of this fixing piece makes it possible to fold the pair of left and right holding pieces, unlike in the past. The bending not only makes it possible to form an inverted trapezoidal egg holding space that can hold eggs horizontally, but also allows the fixing piece to be attached to the tongue piece formed on the bottom piece of the frame block piece. By simply fixing the frame block and bringing the support piece into contact with the fold line of the rear piece and top piece of the frame block piece from the inside, it is possible to easily maintain the shape and position of the inverted trapezoidal egg holding space. There is no need for any insertion grooves, support walls, partition walls, etc., and the processing of the cardboard body is extremely simplified, the multilayering becomes good, and the structure and assembly work are also extremely simplified.

Moreover, the configuration in which the egg is completely fitted horizontally into the through holes of the left and right holding pieces in the inverted trapezoidal holding space is such that both ends of the egg are closer to the entire periphery of the through holes. Since the eggs are held securely, it is completely possible to prevent the eggs from being pushed upwards as in the past, and it is possible to hold the eggs reliably and stably, making it easier to transport the eggs, which was a disadvantage of conventional paper cartons. This also effectively prevents the risk of headbutting and cracking.
