Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to improvement of plastic egg containers used in the distribution process.

<Prior Art> In general, this egg breeding container is a consumable item that is vacuum-formed from a relatively thin transparent plastic material. It is provided with an opening flange having a corresponding rectangular outline and a plurality of egg storage recesses also distributed in a scattered manner, and one long side of the opening flange forms an opening/closing hinge,
The remaining long side is usually heat-sealed.

<Problem that the invention attempts to solve> However, on the wall that partitions each egg storage recess,
In order to safely hold the egg, a large number of reinforcing ribs are arranged in a row, and the entire wall surface is roughened, so the barcode label can be stuck in a stable and firm state without peeling. It is difficult to do so, and even if it were possible to attach it, there is a problem that it cannot be accurately read automatically and mechanically.

On the other hand, the container body and lid are fixed and integrated along the entire long side of the opening flange using heat sealing (thermal welding) means, which should prevent accidental opening during the distribution process. It is difficult to do this with just the fingertips of the hand, and it is difficult to do it lightly and safely using the so-called one-touch method, and it is necessary to apply a considerable force of operation instantaneously, making it easy to accidentally damage the egg.

<Means for Solving the Problems> The present invention is intended to solve these various problems, and for this purpose, the container body and lid body, which are integrally molded from plastic material, have a rectangular outline that joins the palms of each other. The opening flange is extended, one long side serves as an opening/closing hinge, and the container body and the lid are pivoted in a half-folded state, and the other long side facing the opening/closing hinge is
In the egg container, which is sealed in a closed state by applying a heat-sealing part, and in which the container body and the lid are divided into a plurality of egg storage recesses that stand up in opposite directions and are installed in parallel, By forming one short side forming the opening flange as a barcode-applied surface with a longer overhang length than the remaining short side and both long sides, a barcode can be attached to the barcode-applied surface. Directly print or attach the printed barcode label, and heat the rising proximal ridgeline of the egg storage recess on one long side forming the opening flange of the lid. Provide a perforation for opening that is parallel to the ridgeline of the seal part and interposed therebetween, and a tear lead-in line that is continuous with the perforation and is engraved on the barcode-applied surface of the lid. It is characterized by the fact that

<Example> Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated example. In Figures 1 and 2, which schematically show the entire egg container, A is the container body, and B is the lid. They are formed into a continuous and integral piece from a relatively thin and hard transparent plastic material by means such as vacuum forming. The container main body A and the lid B are provided with band-shaped opening flanges 11 and 12 with a rectangular outline that come together when the lid is closed, and one of the long sides serves as an opening/closing hinge 13 and is pivotally connected in a half-folded state. At the same time, the other long side facing this is sealed in a closed state by heat sealing (thermal welding) means.
In this regard, in the illustrated example, a heat seal portion 14 extending along the long sides of the opening flanges 11, 12 is indicated by the reference numeral 14.

In this case, in the present invention, among the opening flanges 11 and 12 that protrude in a rectangular shape from the container body A and the lid B in a band shape, both long sides and one short side facing each other are shown in FIG. As is obvious, the overhang length L1 is all shortened, but only the other short side remains as the barcode application surface 15, and the overhang length L2 is shortened.
is particularly long, so that the barcode C can be directly printed on the barcode-applied surface 15, or a barcode label 16 such as a printed piece of paper can be attached and integrated therewith. It's summery.

In this regard, in the illustrated example, the barcode application surface 15 is connected to the overhanging opening flange 1 of the container body A and the lid B.
Although the opening flanges 11 and 12 are formed at positions and areas that correspond to each other, it is also possible to form the barcode application surface 15 by extending only one of the opening flanges 11 and 12 particularly long. good.

In addition, in the illustrated example, the short sides of the opening flanges 11 and 12 are extended over the entire width direction to form a relatively large area of the barcode application surface 15; By making only the central part of the short sides of the flanges 11 and 12 narrow, so to speak, and protruding particularly long, it is possible to finish the barcode application surface 15 with a relatively small area.

Reference numerals 17 and 18 denote a plurality of egg storage recesses (in the illustrated example, a total of 10 egg storage recesses arranged in two rows of 5 recesses) formed in the container body A and the lid B, respectively, which are connected to the opening flanges 11 and 12. They rise in opposite directions from each other, and in the closed state, they correspond to each other, enveloping the eggs M individually and stably, and keeping adjacent comrades from coming into contact with each other. Egg storage recess 1
7 and 18, as extracted in Figures 3 to 6,
It has a basic octagonal shape when viewed from the top or the bottom, or a polygonal shape close to a circle, and furthermore, it gradually becomes thinner toward the tip in the rising direction.

Each of the egg storage recesses 17, 18 has a polygonal outline, and has opening flanges 11, 1.
2 in opposite directions of the container body A and the lid B, the rising base end ridge line P forms a V-shape in plan and bottom view at the boundary position of the adjacent egg storage recesses 17 and 18. The results are as follows.

Also, 19 and 20 are adjacent egg storage recesses 17 and 1.
8 are integrally connected to each other in the vertical and horizontal directions when viewed from the top and the bottom at a midway position of the rise of a certain height H, h, and prevent adjacent eggs M from coming into contact with each other. 21 is the partition rib 19, 20
At the vertical and horizontal intersection point, the container body A and the lid body B
The fitting convex 22 protruding from one of the two is a fitting groove formed correspondingly to the other, and these fit together when the lid is closed, and the container body A and the lid B are connected to each other. It is designed to prevent misalignment.

Reference numerals 23 and 24 are uneven stripes arranged in rows on the partition wall surfaces of the egg storage recesses 17 and 18 in the container body A and the lid body B, whereby the egg storage recesses 17 and 18 are arranged in rows.
is given shape-retaining strength on egg support. As mentioned above, when the opening flanges 11 and 12 of the container body A and the lid body B are in a state where their hands are joined together, the lid body A and the lid body B are closed by applying the heat sealing part 14. As a result, the opening/closing hinge 13 naturally accumulates a restoring elastic force in the direction in which the lid B is deployed.

25 is the rising proximal ridge line P of the egg storage recess.
and the heat seal part 14,
This is a perforation for opening that is cut in advance on the long side of the opening flange 12 of the lid body B so as to be parallel to the ridge line P. It is processed into a dotted line or chain line shape as shown in the example. Reference numeral 26 denotes a tear lead-in line engraved on the long protruding barcode application surface 15 of the lid body B so as to be continuous with the opening perforation 25, and is provided in a so-called solid line form.

Moreover, the lead-in line 26 for opening is the perforation 2.
The opening flange 12 is provided with a heat-sealed portion 14 so as to extend the end of the flange 5 into a nearly smooth straight line.
It is engraved as a relationship state that intersects the long side of and the acute angle θ in plan and bottom view. Then, when the long protruding barcode-applied surface 15 is easily picked up and held with the fingertips of the operator's hand, and the tearing operation is carried out from the lead-in line 26 as shown by the chain line in FIG. 6, the tearing force is naturally This is surely transmitted to the perforation 25, and the entire long side of the opening flange 12 is quickly torn off, allowing the lid B to be opened.

<Effects of the invention> As described above, in the present invention, opening flanges 11 and 12 with a rectangular outline that join each other are protruded from the container main body A and lid B integrally molded from plastic material, and one long side of the opening flanges 11 and 12 are extended. As an opening/closing hinge 13, the container main body A and the lid B are pivotally supported in a half-folded state, and the other long side facing the opening/closing hinge 13 is sealed in a closed lid state by providing a heat seal part 14. In addition, in the egg container in which the container body A and the lid B are partitioned into a plurality of egg storage recesses 17 and 18 rising in opposite directions and arranged in parallel, one side that forms the opening flanges 11 and 12; By forming the short side of the barcode C as a barcode-applying surface 15 with an overhang length L2 longer than the remaining short side and both long sides, the barcode C can be placed on the barcode-applying surface 15. The barcode label 16 can be printed directly or the printed barcode label 16 can be pasted thereon, and a raised base end of the egg storage recess 18 is attached to one long side forming the opening flange 12 of the lid B. A perforation 25 for opening is provided between the ridge line P and the heat seal portion 14 and parallel to the ridge line P, and a tear lead-in line 26 continuous with the perforation 25 is provided on the lid. Barcode-applied surface 15 of body B
Because it is engraved in the , it has the effect of completely solving the problem mentioned at the beginning.

In other words, in the case of the present invention, among the opening flanges 11 and 12 forming rectangular outlines of the container body A and the lid body B, one of the short sides is larger than the remaining short side or both long sides. Since it is dimensioned to be particularly long with an overhang length L2 and is formed as the barcode application surface 15, the barcode C can be directly printed on this surface and the barcode label 16 can be affixed stably and firmly. , and its reading can be done accurately by automatic mechanical power. Furthermore, the necessary configuration for this purpose is extremely simple, and there is no need to change the molding method of the egg container itself, and changes in the size of the barcode label 16 can be easily accommodated.

Further, on one long side forming the opening flange 12 of the lid body B, there is a line parallel to the ridge line P that is interposed between the rising proximal ridge line P of the egg storage recess 18 and the heat sealing part 14. Perforation 2 for opening
5 is given, and a tear lead-in line 26 that is continuous with the perforation 25 is engraved on the barcode-applied surface 15 of the lid B, making it easy to open the lid B from the container body A. , which has the effect of being extremely easy to carry out and without danger. The barcode-applied surface 15 extends particularly long from the opening flange 12 of the lid B, and a tear lead-in line 26 is provided here, so that it can be easily pinched and held with the fingertips of the operator's hand. If a tearing force is applied thereto to flip it over, the tearing force will naturally be transmitted to the perforation 25 without any force, allowing the lid B to be opened in a rational manner.
