Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a packaging container which can be transported, stored and displayed in a clean state without damaging a plurality of eggs.

[0002]

2. Description of the Related Art Conventionally, eggs which are supplied to the general market are packaged on both sides of a transparent plastic sheet having a thickness of approximately 0.15 to 0.2 mm and sandwiching an opening and closing hinge portion, and having a length of about 1 to about 1 mm. A plurality of egg receiving recesses having a depth of / 2 are formed at symmetrical positions, each serving as a main body and a lid, and an egg with a shell is placed in the receiving recess on the main body side, and then the hinge portion is bent. The other housing recess is covered on the upper half of the egg with a shell (hereinafter, simply referred to as an egg), and furthermore, the flanges formed on the three peripheral edges of the main body and the lid are partially heat-welded. It is customary to keep the lid closed.

As a method for holding the lid closed, Japanese Patent Application No. 61-73945 (Japanese Patent Application Laid-Open No. 5-12203) discloses a method of folding a hinge of a container C by folding a hinge of the container C as shown in FIG. A method is disclosed in which the body is closed, the flanges F, F formed on the edges thereof are overlapped, and the adhesive tape T is folded 180 ° to wrap the two flanges integrally.

[0004] As described above, in order to prevent the main body and the lid from being separated from each other, it is necessary for the egg packaging container to overlap and join the respective flanges. It is a flat plate that protrudes horizontally with respect to the superimposed surface of. Moreover, since the thickness of the plastic sheet is extremely thin as described above, its strength is extremely weak.

[0005] A general consumer who has purchased eggs stored in such a packaging container releases the joint between the main body and the lid by separating the heat-welded portion or peeling off the adhesive tape, and takes out the eggs. The joint strength of the welded portion is large, and the flange portion of the container is torn at the time of separation, and the egg is often damaged due to a momentary breaking shock when the welded portion is opened. Further, in the container in which the two flanges were integrally wrapped with tape, the tape was bent at 360 °, and the peeling was not easy.

The egg container C disclosed in Japanese Patent Application Laid-Open No. 9-278076 has a rib R extending toward the leading edge of a flange F in a housing portion of a main body and a housing portion of a lid as shown in FIG. Is formed in a protruding shape, and the adhesive tape T is stuck over the upper and lower ribs R 1 to hold the lid closed.

According to this, there is an advantage that the area of the adhesive tape can be increased and information such as a bar code and a seller name can be displayed. However, in this case, the tape is formed intermittently. Since the tape adheres to the ribs, the portion of the tape where there is no rib is in a state where the adhesive-adhering surface on the back surface is exposed. Therefore, there is a problem that foreign substances such as dust adhere to the adhesive and are unsanitary.

[0008] Furthermore, various egg storage containers employ a method in which a flat flange formed on a main body and a lid is overlapped and partially heat-welded or tape is partially applied. There is a gap between the overlapping surface of the container body and the lid, and some consumers may be concerned that bacteria including dust or salmonella may enter from this and attach to the eggs. Where you are.

[0009]

[Problems to be Solved by the Invention] Egg packaging containers are molded from a transparent plastic sheet, and it is important that they have good cleanliness and visibility. Therefore, dust does not adhere to the eggs contained in such containers, and it is easy for consumers to check the interior conditions at the time of purchase, for example, whether they are damaged. It is desirable to have an egg container.

[0010] In addition, it is demanded for a person who has purchased eggs that opening of the container is easy in order to prevent damage to the eggs.

[0011]

According to the present invention, two parallel opening / closing hinge portions are formed on a transparent plastic sheet at predetermined intervals, and both of the continuous sheets are sandwiched between the hinge portions. A plurality of egg receiving recesses having a depth corresponding to about half the height of an egg are formed at symmetrical positions to form a rectangular main body and a lid, respectively, and a flange is formed on the entire periphery of the main body and the lid. On the flange surface of the main body (or lid), there is formed a circumferential ridge which is in contact with the edge of the container and has a width which is about half the width of the flange, and which is left outside the ridge. A circumferential band (7c) extending vertically (in the depth direction of the egg-receiving recess) is formed at the edge of the flange having a width of 1/2, and the flange surface of one lid (or the main body) is formed from the edge of the container. Circumferentially outward leaving about half the width of the flange When the main body is covered with a lid having a configuration in which a convex ridge is formed and a vertical surface on the tip side of the circular ridge is extended to form a circular band (8c), the ridge is formed on the flange. The ridges are fitted to each other, and the container for egg packaging is such that dust does not enter the container.

In the invention according to the second aspect, two parallel opening / closing hinge portions are formed on the transparent plastic sheet at predetermined intervals, and the height of the egg is set at both symmetrical positions continuous with the hinge portion interposed therebetween. A plurality of egg accommodating recesses having a depth corresponding to about half are formed to form a rectangular main body and a lid, respectively, and are connected to other edges of the main body and the lid except for the side where the hinge portion is provided. And a flange extending in the horizontal direction, and a tip of the flange is bent in a substantially right angle (in the depth direction of the egg-receiving recess) to form an orbital band-shaped container. In the container described in the above, when the container is closed, the closed state is maintained by applying an adhesive tape made of plastic or the like over two strips that are aligned in the vertical direction. Thin The lid Tadagoto is moved held by pasting tape was no shall ensure internal visibility at the same time.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of an egg container according to the present invention will be described with reference to the drawings. First, the figures will be briefly described. FIG. 1 is a perspective view showing a closed state of the egg container of the present invention, FIG. 2 is a side sectional view of the opened state, and FIG. 3 is an end view of a side sectional view of the closed state. FIG. 4 is an enlarged view showing the fitting state of the container edge in a state where the lid is covered on the main body, and FIGS. 5 and 6 show a conventional example of a closed holding means for an egg container. It is shown.

The egg storage container 1 according to the present invention is made of a transparent plastic sheet as a material, and the eggs are stored on both sheets continuous with the opening and closing hinges 4, 4 formed at predetermined parallel intervals. A plurality of egg receiving recesses 5 and 6 having a depth of about 1/2 are formed at symmetrical positions to form a rectangular main body 2 and a lid 3, respectively, and flanges 7 and 8 are protruded on the periphery of the main body 2 and the lid 3. Then, the peripheral edge of the tip of the main body side flange 7 (or the lid body side flange 8) is bent at an angle of about 90 ° in the depth direction of the egg accommodating concave portion, and the vertical surface 7a is subsequently bent outward. Then, the horizontal plane 7b is further bent at its tip end in the depth direction of the egg accommodating concave portion to form the orbiting band-like portion 7c as if it is stepped. On the other hand, a convex portion 8a is provided around the front end side edge of the lid 3 side flange 8 (or the main body side flange 7) while leaving a half width in contact with the main body, and its outermost surface is extended to form a circular band. This is the part 8c.

When the egg with a shell is accommodated in the egg-housing recess 5 on the main body side of the egg-housing container 1 thus formed, the hinges 4 and 4 are bent and the lid 3 is overlapped on the main body 2. The upper half of the egg with the shell is covered with the above-mentioned egg accommodating concave portion 6, and the flanges 7, 8 formed on the peripheral edges of the main body 2 and the lid 3 overlap each other in an opposed manner. Further, the convex portion 8a formed on the flange 8 is fitted to the vertical surface 7a and the horizontal surface 7b formed by bending following the flange 7, and the orbiting band portions 7c and 8c are brought into contact with their respective bent base ends. They are almost aligned on a straight line (see FIG. 4).

As described above, by covering the main body 2 with the lid 3, the orbiting band-shaped portions 7a and 8a overlap in the vertical direction, so that the band-shaped portions have double widths which are substantially aligned. A circling face plate is formed. In the container for storing eggs according to the present invention, an adhesive tape 9 made of plastic or the like is attached to the face plate portion on the front side to form a seal.

In FIG. 1, a circling face plate portion consisting of a double-width band portion aligned in the vertical direction is formed on the entire periphery of the container, but only on the edge opposite to the hinge forming side. It is needless to say that a circumferential face plate portion may be formed, and the plastic tape 9 is stuck on this surface in the same manner as described above.

The present invention is characterized in that, as shown in FIG. 2, a ridge or the like is formed on the periphery of the container so that the main body and the lid are fitted over the entire periphery. The contact surface is made flat without forming such a fitting portion on the flanges 7 and 8 on the peripheral edge of the container, and is bent at an angle close to a right angle to the leading edge of the flange. What formed the strip | belt-shaped parts 7c and 8c may be sufficient. Since the strength of the flange itself is increased by forming the orbital band-like portions 7c and 8c in this manner, even when the lid is closed, the contact surfaces of both flanges can be closely contacted without being deformed in a wavy shape. become. It is of course possible to keep the lid closed by applying an adhesive tape in such a state.

[0019]

[Effect of the Invention] In the egg container of the present invention having the above-described structure, since the mating surface of the main body 2 and the lid 3 has a fitting structure over the entire periphery, foreign matter enters the container. Therefore, there is no need to worry about bacteria and other pathogens adhering to the eggs.

Further, as a means for closing the main body 2 and the lid 3, an adhesive tape is applied to a strip-shaped portion which is in direct contact with the hinges 4 and 4 on the side opposite to the hinges 4 so that the container can be closed from outside the container. It became possible to see the inside of the camera almost completely. Further, by making the material of the adhesive tape the same as that of the container for storing eggs, even if the tape adheres to the used container, there is no problem in sorting and collecting.

Further, it is a matter of course that a bar code, a product name, a producer name, and the like used in a product confirmation system can be printed and displayed on the surface of the adhesive tape to be attached to the belt-shaped portion.
