 FIG. 1 is a perspective view showing an egg pack 1 according to an embodiment of the present invention, and FIG. 2 is a side view thereof. A pack container in which a main body 2 and a lid 3 are connected by a hinge part 4 and can be opened and closed. 5, a predetermined number of eggs 6 are stored, the pack container is closed, shrink wrapped with a plastic film 7, and the eggs stored in the egg pack 1 are placed on the shrink wrapping film 7. 6. Display or information to convey to consumers or retailers various product information including brand name (trademark), manufacturer, seller, production area, expiration date, storage method, barcode, egg size, optional design, etc. The printed product label 8 is attached with an adhesive or an adhesive.

FIG. 3 is a plan view showing only the pack container 5 in an open state. The main body 2 and the lid 3 formed of a recyclable material such as PET are connected to each other by a hinge 4 and opened and closed. It is possible. A predetermined number (three in this embodiment) of projections 21 are formed on the main body 2, and flanges 22 are formed on three peripheral edges excluding the hinge 4, and the projection 21 and the hinge 4 or Partition walls 23 are formed between the flanges 22 and between the protrusions 21. With this configuration, in this embodiment, eight egg storage recesses 24 are formed in the main body 2, and each egg storage recess 24 has a shape corresponding to a substantially lower half of an egg.

The cover 3 has the same number of protrusions 31 as the protrusions 21 of the main body 2, and has a flange 32 at three peripheral edges excluding the hinges 4. The peripheral wall portion 34 connecting the flange portion 32 and the flat portion 33 is formed as a person having substantially the same inclination angle as the rising surface 21 a forming a part of each egg accommodating recess 21 in the main body 2. ing. With this configuration, when the pack container 5 is closed such that the flange portion 32 of the lid 3 is overlapped on the flange portion 22 of the main body 2, the upper half of the eggs accommodated in the respective egg accommodating recesses 21 of the main body 2. The portion is accommodated between the projection 31 of the lid 3 and the hinge 4 or the flange 32 and between the projections 31, 31 (see FIG. 4).

In FIG. 4, the main body flange portion 22 and the lid body flange portion 32 are shown in close contact with each other. However, physical or chemical bonding for bringing these flange portions 22 and 32 into close contact with each other is shown. No adhesive means (for example, staples, adhesives, etc.) is used at all, and the pack container 5 merely allows the flange portions 22, 32 to be simply overlapped.

FIG. 5 shows the positional relationship between the main body projection 21 and the lid projection 31 in the pack container closed state shown in FIG. A concave portion 21b is formed at the center of the projecting end surface (upper end surface) 21a provided at substantially the same level as the hinge portion 4 and the flange portion 22 in the main body 2. On the other hand, a convex portion 31b is formed at the center of a projecting end surface (lower end surface in the closed state of the pack container) 31a provided on the lid 3 at substantially the same level as the hinge portion 4 and the flange portion 32. In the closed state of the pack container, the front projection 31b of the lid projection 31 is locked so as to fit into the front recess 21b of the main projection 21 so that the flanges 22, 32 are provided as described above. Even in the case of the present invention which does not use physical or chemical bonding / adhering means for bringing the members close together, the displacement between the main body 2 and the lid 3 is effectively prevented.

Returning to FIG. 1 and FIG. 2, the shrink-wrapped plastic film 7 is made of an olefin-based material such as PP which can be incinerated and discarded. Although the pack container 5 in the housed and closed state (FIG. 4) is shrink-wrapped, in the present invention, the whole of the pack container 5 is not shrink-wrapped, but is partially opened on both side surfaces of the pack container 5. Nine. Even in such a shrink wrapping form, the pack container 5 can form and maintain a substantially sealed state by the PP film 7 circling from the back surface of the main body 2 to the surface of the lid 3. It can prevent dust from entering during the distribution stage and ensure the safety of the stored eggs 6. Further, by providing the opening 9 in the shrink wrap, the inside of the pack container 5 and the outside air can be circulated, the cooling effect when stored in the refrigerator is increased, and the shrink wrap during the heating and shrinking process is reduced. Since heat dissipation is promoted, it is possible to prevent thermal deformation of the pack container 5 and eliminate the influence of heat on the eggs 5 inside.

A perforation 10 is formed in advance on the PP film 7 used for shrink wrapping, and the perforation 10 is provided facing the openings 9 on both side surfaces of the pack container 5. In the illustrated embodiment, a perforation 10 extending in the longitudinal direction is formed at the center in the width direction of the main body 2, and the perforation 10 formed at such a position is a space between the egg accommodating recesses 24 of the main body 2. Since the region extends in the longitudinal direction, there is an advantage that the subsequent film cutting operation can be easily performed.

The product label 8 is obtained by printing necessary product information on a material that can be incinerated together with the plastic film 7 as a shrink wrapping material, for example, paper or an olefin-based plastic film, and is adhered onto the shrink wrapping film 7. It is adhered by any adhesive means such as an adhesive or an adhesive.

In the egg pack 1 having the form shown in FIGS. 1 and 2, the hermetically sealed state of the pack container 8 is maintained by the shrink wrapping film 7. Thus, the safety of the stored eggs 6 is ensured.

The consumer who has purchased the egg pack 1 cuts the shrink wrapping film 7 along the perforations 10 before use. As described above, the perforations 10 in this embodiment extend in the longitudinal direction in the space region between the main body protrusions 21 protruding on the back surface side of the pack container 5, and both ends thereof are formed in the pack container 5. 5 faces the opening 9 on both side surfaces, the finger can be put into the space region between the opening 9 and the main body projection 21 to easily perform the cutting operation.

When the shrink wrapping film 7 is completely cut along the perforations 10, the main body 2 of the pack container 5 and the flange portions 22 and 32 of the lid 3 are simply polymerized with each other and are physically and chemically damaged. Since the joining / adhesion means is not used, the closed state of the packing container 5 is automatically released at that moment, and the lid 3 can be opened via the hinge portion 4. Therefore, the opening operation of the pack is extremely easy, and there is no risk of injury to fingers during the operation.

Further, since the product label 8 is attached to the shrink wrapping film 7, the shrink wrapping film 7 is completely cut along the perforations 10, and is simultaneously removed from the pack container 5 together with the shrink wrapping film 7. I do. Since the shrink wrapping film 7 and the product label 8 are both formed of a material that can be incinerated and disposed of, they can be collectively disposed of by incineration, eliminating the need for separating the product label 8 from the shrink wrapping film 7. . Since the product label 8 is attached to the shrink wrapping film 7 at a position that does not interfere with the perforations 10, it does not hinder the cutting operation of the shrink wrapping film 7 through the perforations 10.

In the embodiment described above, the product label 8 is adhered on the shrink wrapping film 7, but instead of attaching the product label 8, necessary product information is replaced with the shrink wrapping film 7. It is also possible to adopt an embodiment in which printing is performed directly on the printer. Even when such an embodiment is adopted, the same operation and effect as in the above-described embodiment can be obtained.

As described above, the container is kept closed by shrink wrapping. At this time, the shrink wrap is formed so as to partially open on both side surfaces of the pack container, and furthermore, cutting guide means that can be torn by hand is provided. It is provided facing the openings on both sides of the pack container, and can be incinerated with the shrink wrapping material on the outer surface of the shrink wrap at a position where it does not interfere with the cutting guide means. It is characterized by the fact that the product label is affixed, so that the packaging and bundling functions can be performed by the shrink wrapping material. Injury during work can be prevented beforehand, and the recyclable packaging material such as PET and the shrink wrapping film and product label such as PP which can be incinerated and discarded are instantly separated by opening the packaging. Only the latter can be disposed of, and the former can be recycled.

According to a preferred embodiment of the present invention, a predetermined number of projections are formed on the main body and the lid of the pack container, respectively, to provide an egg accommodating area in a closed state. A recess is formed at one end of the lid protrusion, and a protrusion engageable with the recess is formed at the other end thereof. This prevents the body and lid from being displaced in the closed state of the pack container, so that there is no means to physically or chemically join and bond the body and lid. In addition, the sealed state of the pack is stably maintained even during the shrink wrapping and the subsequent distribution stages, so that the contamination of the eggs due to the ingress of dust can be prevented.

According to another preferred embodiment of the present invention, since the base surface of the lid of the pack container is formed substantially flat except for the concave portion for forming the projection, the shrink wrap is circular. In addition to providing a smooth support and providing a wide support surface for the product label attached on the shrink wrapping film, the attached state is stabilized, and the product information displayed or printed on the product label can be used. It is easy to see and can be communicated to consumers.

According to still another preferred embodiment of the present invention, a projection for forming the same number of eggs as the number of eggs is provided on the bottom surface of the main body of the pack container. Since the means extends in the longitudinal direction in the space area between the projections, the cutting operation can be performed more easily by putting a finger into the space area between the main body projections from the opening.
