Description

  The present invention swells a synthetic resin sheet material to provide a chicken egg packaging container having a egg containing recess for containing and transferring four, six, eight or ten eggs, and other required numbers. It is about.

  This type of resin sheet packaging container is mainly made of polyethylene terephthalate (PET) resin from the viewpoint of global environmental hygiene, and is well-known for thermoforming such as air pressure forming means and vacuum forming means. A container swelled and formed by means, and is used for sale after such eggs are contained in the container and sealed by appropriate means. This is widely known in general.

  Further, in this kind of egg packaging container, the container body and the cover body covering the upper surface thereof are integrally formed via the hinge portion on one side thereof, and the cover body with respect to the container body It is generally well known that the upper part of the egg is covered by folding it from the hinge part and superposing it on the container body.

  Thus, as a sealing means for this type of egg packaging container, the cover body is covered on the container body, and is formed on one side of the outer peripheral surface of the overlapping joining edge formed to protrude to the free end side. Sealing means is widely adopted in which an adhesive tape coated with an adhesive is bent into a U-shape and bonded. This is also generally well known.

  Thus, this type of egg packaging container is produced in large quantities without any particular inconvenience and is used in large quantities. However, in this type of egg packaging container, in many cases, a wide flat area is formed on the outer surface of the top plate of the lid, and this surface is used as a label affixing surface for the product name or product name of the egg. Label paper on which photographic figures, producers, production dates, expiration dates, and other advertising matters and necessary items are printed is adhered with an adhesive. This is also generally known. However, the purchaser of eggs has been required to remove the label of the container from the necessity of separating and discarding the container and the label after taking out the containing egg.

  On the other hand, during the distribution period after the eggs are stored in the egg packaging container and shipped to the market, or until the opening after the purchaser purchases, moths and small insects are in the container. It can get in and can give buyers a lot of discomfort and hygiene.

  Therefore, as a means for making it possible to fundamentally solve the occurrence of such a situation and making the labor of the label peeling unnecessary, the applicant generally refers to the entire outer peripheral surface of the container as a wrap film. It proposes a means of packaging with a transparent shrink film such as a food packaging film. This is already known now, as can be seen in Patent Document 1 below.

  This egg wrapping means is a very effective means for wrapping eggs and can reliably prevent traps and small insects from entering the packaging container, and the label must be removed from the container. Has been already implemented as a preferred egg wrapping means that can solve the problems of conventional containers.

  On the other hand, there is a view that such an egg wrapping means is less necessary because the egg container in a form in which the eggs are completely covered is further shrink-wrapped. This is an opinion found in Patent Document 2, but the two problems found in Patent Document 1 are not considered in this document.

Thus, in the latter patent document 2, as a container for egg wrapping for shrink film packaging, it can be seen in FIG. 17 and FIG. As described above, a pair of left and right lids 03, 03 are continuously formed on both sides of the container body 02, and protruding portions 07, 07 are formed at both end portions in the longitudinal direction, and formed on the protruding portions 07, 07. By engaging the engaged parts 09, 09 with the engaging parts 011, 011 formed on the container body 02, the lids 03, 03 are kept folded upward, and the egg E A container having a structure in which only the upper part is covered with lids 03 and 03 is shown.

  As described above, in the egg container described in Patent Document 2, the pair of lids 03 and 03 connected to the container body 02 has a structure that covers only the outer upper part of the egg E, and FIG. And like FIG. 18, the upper part of the packaging egg E is left open and is not protected at all. For this reason, even if the entire container is shrink-wrapped, the load on the upper egg that has been stacked will be directly applied to the lower egg at the time of stacked packing in cardboard boxes for transportation or at the time of display for sale. The risk is greatly increased, and it cannot be said that the egg container is a preferable form.

  Therefore, in order to solve the problems of the conventional egg wrapping container, the present invention is configured so that the structure of the container body is directed upward to the center part surrounded by the four egg-containing individual recesses. Two covers that are provided with projecting struts and are integrally connected so as to be foldable upward from both side edges along the longitudinal direction of the container body via respective hinges. In the bent position, the form is provided with a length that extends above the column in the container body, and both of these covers are fitted to the upper surface of the column, or By connecting the two covers to each other so that they are supported on the upper surface so as to cover the upper part of the eggs, the load of the eggs in the upper container at the time of stacked packing or stacked display is supported by the lower container. It is intended to provide egg packaging container has a structure that makes received directly by.

  The first configuration according to claim 1 of the resin sheet-made egg packaging container according to the present invention taken to achieve the object will be described by using the reference numerals used in the examples.

And two cover bodies 2, 3 in the closed positions 22, 32 in the closed position in the closed position. The fitting portion 14 formed on the top surface 13 at a place where the It has a configuration including a convex portion / concave portion or a through-hole shaped engaging portion 24 that fits directly, or an engaging portion 34 that fits indirectly via the mating side engaging portion 24. is there.

  Moreover, the container for egg-wrapping made of a resin sheet according to the second aspect of the present invention includes a container body 1 having individual recesses 11 for individually storing eggs, and opposite side edges 15 of the container body 1. , 15 and two cover bodies 2 and 3 integrally formed so as to be foldable through hinge portions 4 and 4 respectively, and the container body 1 is surrounded by four egg-containing individual recesses 11. And the two cover bodies 2 and 3 are portions 22 and 32 near the free end side, respectively, and in the closed position, the top surface of the support column 12 is provided. 13 is configured to include an engaging body 25 and an engaged body 35 that are engaged with each other in a portion appropriately phased in the direction along the hinge parts 4 and 4 from the top plate parts 21 and 31 that are in contact with 13. It is.

  As described above, the resin sheet-made egg wrapping container having the first configuration according to the present invention is formed by bending the cover covering the upper part of the egg, facing each other from both side edges along the longitudinal direction of the container body. It is assumed that the two cover bodies are arranged in a continuous and freely integrated manner, and in the folded position, the fitting is a concave / convex shape or a through-hole formed on the top surface of the support column in the container body. And a protrusion / concave part or through-hole-type engaging part that can be fitted directly on the upper surface of the column or through the engaging part of the other cover. In the egg packaging position, these two engaging parts are engaged with the engaging part, and the other engaging part is further engaged therewith to fix the two opposing coverings to the container body. When shrink-wrapping the entire container, the container and shrink By interposing a label with necessary information printed between the container and the package, it is possible to immediately separate and dispose of the container and the label at the same time as opening the package. The container in a state can be discarded as a reusable material for reuse or recycling, and a sanitary egg without room for small insects to enter the container before opening can be provided. At the same time, when stacking in a packing box or at the time of sales display, it is possible to provide the market with packaging eggs that have extremely low breakage by allowing the load of eggs in the upper container to be directly received by the support of the lower container. have. Thus, since the load of the upper container at the time of lamination | stacking can be received with the support | pillar of a lower container, even if it is a very thin film as a film for shrink packaging, it has the effect that it fully functions.
