Description

  The present invention relates to an egg wrapping container made of a synthetic resin molded container main body and a lid, and more particularly to an egg wrapping container having a curved-shaped accommodation recess for accommodating an egg.

  As a form of a conventional egg receiving recess, combining the container body and the lid, forming an egg-shaped receiving recess, and providing ribs on the side and bottom of the receiving recess to reinforce the receiving recess, In many cases, a flat surface or a nearly flat surface is formed on the bottom surface of the housing recess, and this can be stably placed as a contact surface with the placement surface.

  For example, as seen in Japanese Utility Model Publication No. 63-40475, the present inventor previously provided four egg storage recesses that can store boiled eggs, formed ribs on the side walls of the container body, and continued to the bottom. It has become well known by developing packaging containers that form a flat surface.

  In addition, the present inventor previously used a hot spring egg container to be purchased outdoors, and the container is formed with a storage recess for holding the egg without rattling, and at the same time the large and small ribs and irregularities for reinforcing the container are A container having a flat bottom surface has been developed and patented. (Japanese Patent No. 2706911)

  The accommodation recess of this type of container is provided with a flat surface at the bottom or a rib that is rich in complex irregularities, so that the accommodation egg is accommodated in partial contact at some points in the accommodation recess. It is supposed to be. This is because most of this type of container is supposed to contain eggs with shells. Even in the case of a container having a rib, since the egg is covered with a shell, it is not necessary to consider so much the pressure that the contained egg receives from the contact portion with the container.

  However, in recent years, it has been demanded to sell processed eggs such as boiled eggs and smoked eggs that have been removed from shells that can be purchased and eaten easily at convenience stores and station kiosks. The processed egg from which the shell has been removed may be deformed or damaged by pressing or pressing from the partial contact portion of the housing recess.

  Therefore, in order to reduce the pressure from the contact portion with the housing recess, the processed egg with the shell removed is accommodated in an egg-shaped curved housing recess or an egg packaging container having a housing recess close to the egg-shaped curved surface. It is possible to do.

On the other hand, in recent years, convenience stores and station kiosks have been requested not only to place and sell on a plane, but also to form a hanging hook and sell it in space, but as a conventional hook, In Japanese Utility Model Publication No. 2-38347, there is a question-type hook, and in Japanese Patent Application Laid-Open No. 2001-180292, there is a round hole, although it is used as a solar shielding plate storage device. Those with hooks are well known.

  However, as the shape of the housing recess, as in the former case, if it is an egg packaging container with an egg-shaped curved housing recess or an accommodation recess close to the egg-shaped curved surface, the boiled egg, smoked, with the shell removed Even in processed eggs such as eggs, and other eggs with shells, the accommodation recess is an egg shape or a curved surface close to an egg shape, so that the accommodation egg is not subject to local pressure from the accommodation recess. Although it is excellent in maintainability, on the other hand, it has a curved housing recess, and more specifically, since the bottom surface of the housing recess is curved, it can be stably mounted on a flat mounting surface. It cannot be placed, and the contents are difficult to view when placed randomly.

  In addition, as a form of the hanging hook, if it is a question type hook as in the latter case, it is easy to suspend and remove it from the hook bar, but the hook bar will come off from the question type gap. Easy and closed circular hole hook, the hanging state is stable, but the hanging to the hook rod is to move the hook rod to the tip of the hook rod and insert the hook rod into the hook hole In addition, it is necessary to move the container to the tip of the hook bar and remove the container from the hook bar, and it takes time and effort to hang and remove it from the hook bar. Each of these points has its own problems.

Therefore, the present invention can be stably placed on a flat surface for an egg packaging container in which a housing concave portion for accommodating a processed egg such as a boiled egg or a smoked egg from which a shell has been removed is curved. An egg packaging container is provided. It is another object of the present invention to provide an egg wrapping container that can be stably suspended from a hook while being easily suspended and removed from the hook.

The structure of the present invention taken to solve this problem will be described using the reference numerals used in the drawings showing the embodiments. The egg wrapping container of the present invention includes a container body 1 and a lid formed from a synthetic resin material. An egg wrapping container comprising a body 2, wherein the container body 1 lays processed eggs such as boiled eggs and smoked eggs from which shells have been removed on a flat surface 14 having a substantially rectangular shape, and laid eggs sideways. In a state where the lower half portion can be accommodated in a surface contact with a smooth curved surface, and the outer periphery of a substantially rectangular flat surface has a substantially inverted U-shaped cross section. An annular ridge portion 15 is formed, and a flange portion 12 is projected outwardly from the outermost edge of the substantially inverted U-shaped annular ridge portion 15, and the lid body 2 is closed on the outer periphery thereof. A flange portion 22 that overlaps with the flange portion 12 of the container main body 1 in the lid posture is formed. Hamagodan portion 25 in closed position on the inner peripheral side from the edge accept annular ridge portion 15 of the container body 1 Yes formed, the curved housing recess 11 projects toward the outer surface side of the The horizontal mounting posture maintaining protrusion 3 is formed.

Still another configuration of the present invention is an egg wrapping container including a container body 1 and a lid body 2 formed from a synthetic resin material, and the container body 1 includes a boiled egg and a smoked egg from which a shell has been removed. the processing eggs circumferential shape substantially rectangular flat surface 14 equal, with smooth curved housing recess 11 as the lower half portion in a state of aged eggs sideways can be housed in surface contact, An annular ridge 15 having a substantially inverted U-shaped cross section is formed on the outer periphery of the substantially rectangular flat surface, and outward from the outermost edge of the substantially inverted U-shaped annular ridge 15. A flange portion 12 is formed so as to project toward the end, and the lid body 2 is formed with a flange portion 22 that overlaps with the flange portion 12 of the container body 1 in a closed posture on the outer periphery thereof, and an end on the inner periphery side thereof. A fitting step portion 25 for receiving the annular ridge portion 15 of the container body 1 in a closed posture from the edge to the inner peripheral side is provided. Yes form, wherein the curved housing recess 11 horizontal mounting postures maintaining projections 3 projecting toward the outer surface side is formed, the outer integrally from each of the peripheral edge of the container body 1 and the lid 2 A first tongue piece 13 and a second tongue piece 23 projecting toward the direction, and the first tongue piece 12 and the second tongue piece 22 are superposed at the respective tip portions in a closed posture, The hook hole 4 for suspension is formed.

  According to the first aspect of the present invention, since the horizontal mounting posture maintaining protrusion protruding outward is formed in the curved concave portion of the container main body, the horizontal mounting posture of the container can be maintained. , Can be arranged in an orderly arrangement on a plane at the time of sale, can be used while being stably placed horizontally on the plane even at the time of use, and in any case a constant horizontal placement posture Since it can be maintained, the state of the contained eggs can be easily recognized and easily confirmed. In addition, since the horizontal mounting posture maintaining projections that protrude toward the outer surface side can be formed integrally with the other parts of the container using a mold, the labor and cost are almost the same as those of the conventional container. Can be molded without change.

According to the second aspect of the present invention, since the horizontal mounting posture maintaining protrusion protruding outward is formed in the curved housing recess of the container body, the horizontal mounting posture of the container can be maintained. , Can be arranged in an orderly arrangement on a plane at the time of sale, can be used while being stably placed horizontally on the plane even at the time of use, and in any case a constant horizontal placement posture Since it can be maintained, the state of the contained eggs can be easily recognized and easily confirmed. In addition, since the horizontal mounting posture maintaining projections that protrude toward the outer surface side can be formed integrally with the other parts of the container using a mold, the labor and cost are almost the same as those of the conventional container. Can be molded without change. In addition, a first tongue piece and a second tongue piece integrally projecting outward from the respective peripheral edges of the container main body and the lid body, and the first tongue piece and the second tongue in the closed position are provided. Since the hooks for hanging are formed by overlapping the pieces at the respective tip portions, it can be suspended and sold using the formed hook holes. The space can be used effectively and sold. In addition, the effect is that the hook rod is pressed against one or both of the first tongue piece and the second tongue piece, and the first tongue piece and the second tongue piece are actuated away from each other to form a gap. Then, the hook rod can be slid from the formed gap, and the hook rod can be inserted into the hook hole, so that the hook hole is aligned with the tip of the hook rod and the hook rod is inserted into the hook hole The container can be suspended from the hook bar simply and quickly. At this time, the gap formed by cleaving the overlapping portion of the first tongue piece and the second tongue piece is temporary due to the pressing of the hook bar B, and the hook bar B moves to the hook hole through the gap. Then, the first tongue piece and the second tongue piece operate in a direction in which they are brought into close contact with each other by a restoring force, so that the first tongue piece and the second tongue piece are not broken and detached from the hook bar when suspended. It can be used as a hook for general suspension. Further, by twisting the container in either the horizontal direction from the state in which the container is suspended from the hook bar, a gap can be formed in the overlapping portion of the first tongue piece and the second tongue piece. Since the hook bar can be removed from the hook bar, there is no need to move the container to the tip of the hook bar to remove the container from the hook bar, and the container can be easily and quickly removed from the hook bar. Thus, for example, even when a large number of containers are hung on the hook bar and it is desired to hang a new container in the back, it is hung on the side closer to the tip of the hook. You can easily hang a container where you like without removing it one by one, and even if there is a container you want in the back, you can hang a container that is suspended closer to the tip of the hook. You can easily remove the container you want without removing it.

In carrying out the present invention, the shape, structure, number, and the like of the horizontal placement posture maintaining protrusions 3 projecting toward the outer surface formed in the curved housing recess 11 are determined so that the stored egg is locally pressed from the housing recess. And within the range satisfying the effect of being able to maintain the horizontal mounting posture with the receiving recess 11 and the horizontal mounting posture maintaining protrusion 3 or with the horizontal mounting posture maintaining protrusion 3. It may be carried out in a form that seems to be best as appropriate, but from the viewpoint of horizontal mounting, when the horizontal mounting posture is maintained by the housing recess 11 and the horizontal mounting posture maintaining projection 3, it protrudes toward the outer surface side. The projecting end of the horizontal mounting posture maintaining projection 3 is positioned so as to be at the same depth as the deepest portion 11a of the housing recess 11 in the horizontal mounting posture, and the horizontal mounting posture maintaining projection 3 alone is used for horizontal mounting. If you want to maintain posture, The protruding end of each horizontal mounting postures maintaining projections in the mounting postures performed such that the position of the same depth.

  In carrying out the present invention, the material is not particularly limited, but is inexpensive, easy to mold, and when implemented with the configuration of claim 2, the first tongue piece 13 and the second tongue piece. The material which can give moderate elasticity to 23 is used, and it implements on the molding conditions which can give moderate elasticity to the 1st tongue piece 13 and the 2nd tongue piece 23. FIG.

  Embodiments of the present invention will be described below together with illustrated examples. FIGS. 1 to 7 are views showing a first embodiment of the present invention, in which FIG. 1 is a perspective view in an opened state, FIG. 2 is a perspective view in a closed state, FIG. 3 is a plan view in an opened state, 4 is a side view of the lid open state, FIG. 5 is an enlarged perspective view of the horizontal placement posture maintaining protrusion 3, and FIG. 6 is a partially enlarged view of the overlapping portion of the first tongue piece 13 and the second tongue piece 23. 7 is a perspective view in a state of being suspended from a hook bar, and FIG. 8 is a side view of a closed state of being placed on a flat surface.

  The egg packaging container according to the first embodiment is formed by integrally forming a container body 1 and a lid body 2 via a bent portion 5. In consideration of ease of molding and cost, the material is a sheet of polyethylene terephthalate resin processed from various synthetic resin materials, and molded using well-known blow molding means and vacuum molding means. is doing.

  As shown in FIG. 1, the container body 1 has a smooth curved surface that can accommodate the lower half part in surface contact with the egg lying sideways on a flat surface 14 having a substantially rectangular shape. Are formed integrally, and an annular protrusion 15 having a substantially inverted U-shaped cross-section is formed on the outer periphery of a substantially rectangular flat surface. The flange portion 12 is formed so as to project outward from the outermost edge of the annular ring-shaped ridge portion 15. And, from the position slightly shifted in the width direction from the center portion of the flange portion 12 on the free end side of the container body 1, the first tongue piece 13 having a triangular shape is extended outwardly integrally with the flange portion 12, It is protrudingly molded.

  The accommodation recess 11 is an egg-shaped opening as seen in a plan view of FIG. 3. In this embodiment, the accommodation recess 11 accommodates the egg head facing the free end in the state where the egg is laid sideways. A structure in which the head of the egg is accommodated toward the connecting side, that is, a structure in which the head of the egg is down when the container is suspended as described later may be employed. Moreover, the accommodation recessed part 11 is made into the shape where the bottom face of the free end side curved upwards, seeing the side view of FIG. Then, a horizontal mounting posture maintaining protrusion 3 having a predetermined width is formed so as to protrude from the central portion in the width direction near the free end side of the housing recess 11 to the outer surface side. As shown in FIGS. 4 and 5, the horizontal mounting posture maintaining projection 3 has a bottom surface 3a having a predetermined width extending from the deepest portion 11a of the housing recess 11 toward the free end side, and having the same width from the free end side end. It consists of a rising surface 3b that is raised upward and connected to the egg-receiving surface of the free-end egg that is warped upward, and both side surfaces 3c having a substantially triangular shape. The structure is arranged in the longitudinal direction.

  As shown in FIG. 1, the lid body 2 is formed with a flange portion 22 that overlaps with the flange portion 12 of the container body 1 in the closed posture on the outer periphery, and from the inner peripheral side edge to the inner peripheral side. A fitting step 25 for receiving the annular protrusion 15 of the container main body 1 in the closed posture is formed on the inner peripheral side of the container body 1 so as to reinforce the lid 2. An annular reinforcing rib 24 is formed. A second tongue piece 23 formed in a bowl shape is integrally formed with the flange portion 22 so as to project outward from a position slightly shifted in the width direction from the center portion of the flange portion 22 on the free end side of the lid body 2. It is. The second tongue piece 23 is formed with a reinforcing rib 23a having the same shape as the outer periphery of the second tongue piece 23.

  Thus, as shown in FIG. 2, in the closed posture, the distal end portion 13 b of the substantially triangular first tongue piece 13 formed on the flange portion 12 of the container body 1 and the flange portion 22 of the lid body 2 The tip portion 23b of the formed bowl-shaped second tongue piece 23 is superposed, and is surrounded by the first tongue piece 13, the second tongue piece 23, the flange portion 12 of the container body 1, and the flange portion 22 of the lid 2. In the region, a hook hole 4 is formed through which a hook for hanging sales is inserted. The hook hole 4 is determined so as to be positioned at the center in the width direction so that the right and left balance can be obtained when suspended, and the first tongue piece 13 and the lid for the flange portion 12 of the container body 1 are accordingly configured. The position and shape of the second tongue piece 23 with respect to the second flange portion 22 are determined.

  Immediately after the lid is closed, the first tongue piece 13 (the front end portion 13b) formed on the flange portion 12 of the container body 1 is the lower portion, and the second tongue piece 23 (the front end thereof) formed on the flange portion 22 of the lid body 2. Portion 23b) is at the top, but as shown in FIG. 2, the tip portion 23b of the second tongue piece 23 is crossed under the tip portion 13b of the first tongue piece 13 and polymerized (that is, (By intersecting the overlapping portions of the first tongue piece 13 and the second tongue piece 23), the action of returning to the lower side of the front end portion 13b of the first tongue piece 13 intersected with the upper part, and the second intersecting with the lower part. The action of returning to the upper side of the tip 23b of the two tongue pieces 23 works, and the overlapping portions of the first tongue piece 13 and the second tongue piece 23 are brought into close contact with each other to form the annular hook hole 4.

  In order to insert the hook bar B into the hook hole 4 formed in this way, the first tongue piece 13 and the second tongue piece 23 are crossed from the lower part of the hook bar B and the overlapped portion is brought close to FIG. As shown, the hook bar B pushes the second tongue piece 23 (and the first tongue piece 13) and pushes it into the intersecting side, thereby cleaving the overlapped portion of the first tongue piece 13 and the second tongue piece 23. When the container is moved so that the hook bar B is slid into the formed gap, the hook bar B is moved to the hook hole 4, and the container is released, as shown in FIG. The second tongue piece 23 (and the first tongue piece 13) act in a direction to come into close contact with each other again by a restoring force, and a strong and stable hook is formed again, while the hook bar B is inserted into the hook hole 4. Thus, a state in which the container is suspended is realized.

  On the other hand, by twisting the container in the left-right direction from the state in which the container is suspended in this way, the overlapping portion of the first tongue piece 13 and the second tongue piece 23 is cleaved to form a gap. By pulling out the hook bar B from the gap, a state in which the container is detached from the hook bar B is realized.

  FIG. 8 is a diagram in which the container is placed on a flat surface. As described above, the egg storage surface has a shape in which the bottom surface on the free end side is warped upward, and the horizontal placement posture maintaining projection 3 When a container in which no is formed is placed on a flat surface, the container falls down forward, but the bottom surface 3a of the horizontal placement posture maintaining protrusion 3 is formed so as to be at the same depth position as the deepest part 11a of the housing recess 11. Therefore, the structure is supported by the deepest portion 11a of the housing recess 11 and the bottom surface 3a of the horizontal placement posture maintaining projection 3 and can be stably placed horizontally. On the other hand, as shown in FIG. 3, since the horizontal placement posture maintaining protrusion 3 is formed, the accommodation surface of the egg accommodation recess 11 is partly cut off. Only the contact portion is formed, there is no partial pressure on the contact portion, and there is no particular disadvantage in accommodating eggs.

FIG. 9 is a perspective view of the egg packaging container according to the second embodiment in an open state, and the first tongue piece 13 and the second tongue piece 23 are different from the egg packaging container according to the first embodiment. It is not formed (that is, the hook hole 4 for suspending is not formed in the closed posture), and the other structure is the same as that of the first embodiment .

  FIG. 10 is a perspective view of the egg wrapping container of the third embodiment in an open state, and differs from the egg wrapping container of the first embodiment in that only one curved recess 11 is formed. Accordingly, the length in the width direction of the container is reduced. Further, the horizontal mounting posture maintaining projection 3 is 90 degrees from the bottom surface portion of the housing recess 11 that warps upward on the free end side in a side view of FIG. It is arranged in the horizontal direction by rotating in the horizontal direction, that is, in a substantially rectangular parallelepiped structure in which the long portion of the bottom surface 3a is arranged in the width direction of the container, and is protruded from the outer surface side. In the case of a container in which only one curved housing recess 11 is formed as in the present embodiment, the long portion of the bottom surface 3a of the horizontal placement posture maintaining projection 3 is placed on the container as in the first embodiment. When placed in the longitudinal direction, the container tends to roll over in the width direction and is unstable, but by arranging the long portion of the bottom surface 3a in the width direction of the container, the risk of rollover in the width direction of the container is reduced. As shown in FIG. 11, the longitudinal direction of the container also includes the deepest portion 11 a of the housing recess 11 and the bottom surface 3 a of the horizontal placement posture maintaining protrusion 3 formed at the same depth as the deepest portion 11 a of the housing recess 11. It has a structure that can be supported horizontally and stably placed horizontally. Other structures are substantially the same as those in the first embodiment.

FIG. 12 is a perspective view of the egg packaging container of the fourth embodiment in an open state, and the first tongue piece 13 and the second tongue piece 23 are formed, which is different from the egg packaging container of the third embodiment. (Ie, the hook hole 4 for suspending is not formed in the closed posture), and the other structure is the same as that of the third embodiment .

  Although the embodiment considered to be a representative example of the present invention has been described above, the present invention is not limited to the above-described embodiment. For example, the horizontal placement posture maintaining protrusion 3 is other than the configuration shown in the embodiment. In addition, it may be configured to be provided respectively on the front side and the back side of the housing recess 11, and has the above-described configuration requirements referred to in the present invention and achieves the object referred to in the present invention. It can be implemented with appropriate modifications within the range it has.
