Description

  The present invention relates to a chicken egg wrapping container made of a resin sheet, in which a container body and a lid are integrally connected to each other so as to be bent and folded via a hinge portion at one side thereof.

  Conventionally, this type of resin sheet egg packaging container is well known as a packaging container for storing and protecting eggs in a container. In a container for packaging eggs of this kind, the lid is folded from the bent portion with respect to the container main body so as to be overlapped on the container main body, and the upper part is covered on the outer peripheral surface of the joint edge on the free end side. A packaging means is used for sealing by folding and bonding a pressure-sensitive adhesive tape coated with an adhesive on one side into a U shape when viewed from the side. In addition, a means of sticking a label printed with a nickname or trademark of a packaged egg, a product name, a producer name, a production date, or an expiration date to each container by a machine is adopted. Furthermore, the containers in which eggs are packaged are stacked up and down for distribution, and are also displayed up and down for sale.

The sealing means by tape bonding is usually automatic sealing means by using a mechanical device, and the outer peripheral edge of the joining edge along the longitudinal direction of the container is transferred while the container in the closed position is transferred by the conveyor. A means is adopted in which the upper and lower portions in the width direction of the tape are bonded to the upper and lower surfaces of the container joint edge while being folded into a U shape when viewed from the side by a mechanical device while being applied to the middle portion of the upper and lower width of the tape. Moreover, the label which printed the various information of the packaged hen's egg also employ | adopted the thing which apply | coated the adhesive material on the back surface, and is affixed on the surface of the cover body with the machine.

In order to reliably perform the sealing means for sealing while folding the adhesive tape in a U shape when viewed from the side using the above-mentioned machine, the free end edges of the container body and the lid are always closely overlapped, It is necessary to be folded so that there is no deviation in the direction. In other words, it is preferable that the joint edge on the free end side of the lid body is overlapped exactly vertically on the joint edge on the free end side of the container body without shifting in the front-rear direction and in the overlapping direction. Second, it is preferable that when the label is attached by a machine, the label can be correctly attached at a predetermined position, and when the container is discarded, the label can be easily peeled off. Thirdly, since eggs are vulnerable to impact and easily break, when stacking eggs containing containers up and down in a sales display position, contact the individual recesses in the upper container to ensure the stacked state. It must be maintained and not slipped down.

  The present invention allows the lid body to always be exactly superimposed on the container main body in a predetermined form when the lid is closed, the inside of the container can be reliably seen through, and the label can be correctly attached at a predetermined position. An object of the present invention is to provide a container for egg wrapping which can be easily peeled off when the container is discarded and which can maintain the stacked state reliably.

In order to achieve the object, the resin sheet egg packaging container according to the present invention has a container body 1 having an individual recess 11 for accommodating the lower half of the egg and a recess 21 that covers the upper surface of the egg. And a lid 2 provided with a resin sheet egg packaging container integrally formed so as to be foldable and foldable on one side thereof via a hinge portion 3, wherein the lid 2 is a flat canopy portion 21A, each of which protrudes upward in the closed position at each of its four corners as protrusions that contact the individual recesses of the upper container when the containers are stacked and prevent the upper container from sliding down. A plurality of granular protrusions 24 for preventing slip-off are formed.

Since the present invention is configured as described above, in the container of the present invention, the lid body has a flat canopy portion, and each of the four corner portions is directed upward in the closed posture. Since it has a configuration in which a plurality of individual protruding protrusions for preventing slipping are formed individually, the protrusion can be made stronger than the ribs connected in a rib shape. It has the practical effect of preventing accidents such as the ridges being crushed like a ridge and not serving as ridges, and the upper container piled up sliding down and surely eliminating sliding down. It has come to be expected.

  Hereinafter, the configuration of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing the overall shape of the container, FIG. 2 is a plan view of the container, FIG. 3 is a front view thereof, FIG. 4 is a rear view thereof, FIG. 5 is a right side view thereof, and FIG. It is the fragmentary figure which expanded and showed the right end part in the described cover body.

  Thus, the eggs packaging container shown in this embodiment diagram has two rows in the front and rear (upper and lower sides in the figure) as seen in the egg receiving recess 11 shown in the lower half container body 1 in FIG. It shows a container used for storing and packaging a total of six eggs in total, three on the left and right. This egg-containing recess 11 has five containers on the left and right, a total of ten containers, four on the left and right, a total of eight, six on the left and right, a total of twelve containers, three rows in the front and rear, five on the left and right, a total of 15 There is also a container.

  This egg egg wrapping egg container is formed by integrally connecting the container body 1 and the lid body 2 using a synthetic resin sheet material so that the container body 1 and the lid body 2 can be folded and folded via a hinge portion 3 at one side thereof. The eggs are packaged by individually storing the eggs in the six egg receiving recesses 11 formed in the container main body 1 and then bending the lid 2 upward and forward from the hinge portion 3. 1, the joint edge 14 on the free end side of the container body 1 and the joint edge 24 on the free end side of the lid 2 are overlapped, and the joint edges 14 and 24 are overlapped exactly. As the state, the outer edge is applied to the sealing tape with the adhesive applied to one side in the widthwise middle part, and the tape is folded in a U-shape when viewed from the side while being wrapped from outside. It is sealed.

  The container shown in this embodiment is located above the container body 1 out of the container body 1 and the lid 2 along the entire circumference including the four corners of the outer peripheral edge of the container body 1 and the lid 2. A rib-like protrusion 13 protruding toward the surface is formed continuously, and the lid body 2 is provided with a peripheral wall surface 23a that receives the protrusion 13 and has a size and a shape that are in close contact with the outer peripheral surface of the protrusion 13. A protrusion receiving portion 23 is formed.

  Further, the lid body 2 is provided with a substantially rectangular recessed portion that covers the upper half of the egg, and the canopy portion 21A that forms the bottom of the lid body 2 is formed on a substantially flat surface except for the portion where the support column 25 is formed, In FIG. 2, a flat surface 21a is left on one side parallel to the hinge portion 3 on the lower side, and the remaining portion is formed on a small mesh-like uneven surface 21b. Further, among the peripheral walls 22 of the lid body 2, a large number of vertical rib surfaces in a state in which the peripheral wall 22 b on the side continuous with the small uneven surface 21 b, that is, the upper peripheral wall 22 b in FIG. A continuous label sticking surface is formed over the small uneven surface 21b and the peripheral wall 22b.

Further, as the protrusions that come into contact with the individual recesses of the upper container when the containers are stacked and prevent the upper container from slipping down, the four corner portions of the canopy portion 21A of the lid body 2 are arranged on the upper side in the closed position. 1 and 4, a plurality of individual granular protrusions 24 are formed to project downward and prevent slipping individually. More specifically, in FIG. 2 showing the lid portion and FIG. 6 showing an enlarged view, four granular protrusions 24 are formed in an arc shape at the lower corner, and at the upper corner. Three granular protrusions 24 are formed in an arc shape, and compared to the lower four granular protrusions 24, a portion that is offset toward the center side in the lateral width direction is cut and does not exist.

  The container shown in this embodiment has a projection 13 formed along the entire circumference including the above four corners when closed, and a peripheral wall surface 23a having a size and a shape almost in close contact with the outer peripheral surface of the projection 13. The projection receiving portion 23 provided with the projection is fitted into the container body 1 and the lid body 2 while being in contact with each other without being displaced. Both bodies 1 and 2 maintain a substantially sealed state by the peripheral wall surface 23a of the receiving portion 23, and the joint edge 20 on the free end side of the lid body is placed in the front-rear direction on the joint edge 10 on the free end side of the container body. It is possible to obtain a state where the upper and lower portions are almost exactly overlapped without shifting and without opening in the overlapping direction.

In addition, the lid body 2 is formed with the other surface on the small uneven surface 21b while leaving the flat surface 21a on which the small uneven surface is not formed on one side parallel to the hinge portion 3, and the peripheral wall 22b connected thereto is also vertically Since the label sticking surface is formed on the rib surface and continuous across the surface of the vertical rib and the small uneven surface 21b, the inside can be easily seen through while ensuring a wide label sticking surface. Further, as described above, when the containers are stacked , the protrusions come into contact with the individual recesses of the upper container to prevent the upper container from sliding down, and are directed upward at the four corners of the lid body 2 in the closed position. By forming the plurality of individual granular protrusions 24 for preventing slipping and projecting individually, the granular protrusions 24 that are not easily crushed can surely prevent the upper stacked container from slipping down.

  In particular, the granular projections 24 on the label application surface side are divided into three granular projections 24 formed in an arc shape at the upper corner corner in FIG. 6 as described above, and an arc is formed at the lower corner corner portion. When compared with the four granular protrusions 24 formed in a shape, the portion that is offset toward the center side in the lateral width direction, that is, the portion in the direction in which the small uneven surface 21b is formed, is cut off to form a label. The width of the sticking surface is formed to be as wide as possible, and at the same time, care is taken to ensure that the labeling by the machine can be performed without any trouble.

  Although the embodiment considered to be representative of the present invention has been described above, the synthetic resin container referred to in the present invention can be implemented by changing its shape to an appropriate shape.
