Description

  The present invention relates to a so-called regular-type plastic egg packaging container, and more particularly to improve the bar code label in a plurality of stacked states.

  There are 4 to 5 types of eggs packaging containers that are integrally molded from transparent or translucent thin plastic sheet material, and there are 4 to 5 different sizes for each egg size. At the center, the line is transported in a mixed state, and the sorting operator visually sorts it from the gathered turntable, and the sorting work concentrates the nerves as an inspection of eggs that are products. Therefore, the inspection of the bar code label in the packaging container must be sweetened.

  On the other hand, the manufacturer of egg packaging containers assembles a rectangular flat outline packaging container as a line that transports along the longitudinal direction (front-rear direction), and either one of the short edge flange side (width direction) It is customary to automatically and automatically attach a bar code label to the packaging container.

  In that case, when the bar code label is affixed here with the adjacent boundary part of the egg storage recesses lined up on either short edge rim flange side of the container body as a flat label affixing surface, the container body side The egg storage recess of the taper has a tapered (bottom-thin) truncated cone shape and a truncated regular polygonal pyramid shape, so the labeling surface is also a diagonally downward wall, and the barcode label attached here It is difficult to see from above, and as a result, sorting work at the GP center and barcode reading work at a store cannot be performed easily and accurately.

  Further, a flat surface (3) or a flat surface (shown in FIG. 2 of Patent Document 1 (Japanese Patent Laid-Open No. 59-84773) and Patent Document 2 (Japanese Utility Model Laid-Open No. 61-164180)) ( 7) as a top surface (3) or an inclined standing wall surface (7) to the adjacent boundary portion of the egg storage recess (1b) arranged on either short-edging flange side of the lid (B) Or a plurality of flat surfaces (7) and (7) which will be continuous at the time of covering as described in FIGS. 3 and 4 of another patent document 3 (Japanese Utility Model Publication No. 62-11779). It is also well known that the material is shaped in a scattered distribution state correspondingly positioned along the longitudinal direction of the container body (1) side and the lid body (2) side.

  However, the barcode label (5) affixed to the flat top surface (3) of Patent Documents 1 and 2 cannot be visually observed when the egg packaging containers are stacked.

  Similarly, when a barcode label is affixed to the flat inclined wall surface (7) of Patent Documents 1 and 2, there is an advantage that it is easy to see, but the height of the inclined wall surface (7) is the lid (B). Since it is at the same high level as that of the egg storage recess (1b) on the side, so-called regular type egg packaging containers are small in dead space and cannot be stacked stably.

  In the regular type egg packaging container, the egg storage recess (1a) on the container body (A) side and the egg storage recess (1b) on the lid (B) side are alternately arranged in the longitudinal direction. When stacked as an occlusal state shifted in the width direction, the height of the inclined standing wall surface (7) formed only on the short-edging flange side of either one of the lid (B) is at a high level, Since the adjacent boundary part between the egg storage recesses (1b) is not depressed, only one of the egg storage recesses (1a) located on the short side edge flange side of the upper packaging container is It is because it will ride on the top surface (3) of a high inclined standing wall surface (7), and will be in a steep inclination state.

  In this respect, the height of the flat surface (7) described in Patent Document 3 is lower than that of the egg storage recess (4b) on the lid (2) side, and the egg storage recesses (4b) are not connected to each other. Since it exists in the same height level as a partition partition (5), it can be said that the said problem at the time of stacking like patent document 1, 2 does not arise.

  However, the flat surface (7) for affixing the barcode label (A) is installed in a distributed state along the longitudinal direction of the container body (1) side and the lid (2) side. For this reason, it is necessary to reassemble the egg packaging container conveyance line as a whole including the position of the bar code label attaching machine, which entails a great deal of cost and time.

  Furthermore, in the configuration in which the flat surface (7) for attaching the barcode label is installed along the longitudinal direction of the egg packaging container on either the open / close hinge side or the free end side, the roll after the sorting operation is performed. When loaded in a dedicated rack called an inner and transported or displayed, the barcode label of the egg packaging container cannot be seen from around the roll inner, and the inspection work cannot be performed.

  The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, a transparent or translucent plastic sheet material is integrally formed into a substantially rectangular planar contour shape having the same size. A pair of a container body and a lid body are connected to each other by a half-folding open / close hinge with a constant band width that is interposed at the boundary between adjacent long side edge flanges. It can be pivoted continuously so that it can come into full contact with the palms,

  Inside the compartment surrounded by the border flange of the container main body and the lid body, a plurality of egg storage recesses that are recessed in the vertical direction opposite to the joint plane are separated by a partition lattice wall in a state of being vertically and horizontally orthogonal to each other. Divide and partition into a lattice state where adjacent eggs do not contact each other,

  A regular type egg packaging container in which an intermediate partition column that can be fitted at the time of application is raised from the vertical and horizontal orthogonal parts of each partition lattice wall in the container body and the cover body in a direction opposite to the egg storage recess. In

Peripheral partition convex walls that can come into surface contact with the palms at the time of lid application from the portions where the partition grid walls of the container body and the lid intersect at right angles to both the long side edge flanges and one of the short side edge flanges. , Raised in the same direction as a planar contour shape of the thickness of the middle partition column divided into two halves,

Among the peripheral partition convex walls distributed in a plurality of locations on the container body side, a long side edge flange extending to the free end side of the container body and one short side edge flange are perpendicular to the partition lattice wall. Only those located at the crossovers are raised upwards by a certain height from the above-mentioned palmar plane,

Similarly, a crescent-shaped corner fitting convex wall in a plan view is connected to the peripheral partition convex wall from a long-side edge flange extending to the free end side of the container body and a circular arc corner portion perpendicular to both short-side edge flanges. Raise upward by the same constant height,

The outer wall surface of the raised portion is a flat insertion inclined surface, and a convex rib receiving groove is cut out on the insertion inclined surface.

Furthermore, a rail-shaped fitting convex step surface extending along both short-side edge flanges on the container body side is set at a certain height from the joint plane until reaching a circular arc corner portion perpendicular to both long-side edge flanges. While only raising upwards,

A lid-side peripheral partition convex wall that can be fitted with the peripheral partition convex wall on the container body side at the time of covering, a long-side rim flange extending to the free end side of the lid, and one short-side rim flange; Only those located at the right-angled intersection with the partition grid wall are recessed upwards by a corresponding fixed depth from the above-mentioned palm plane,

The outer wall surface of the depressed portion is a flat receiving inclined surface substantially parallel to the insertion inclined surface on the container main body side, and a convex rib that can be fitted from the receiving inclined surface to the convex rib receiving concave groove on the container main body side. Projecting inward,

Similarly, a corresponding crescent-shaped corner fitting concave step surface on the lid side that can be fitted with the above-mentioned corner fitting convex wall on the container body side when the lid is applied is a long-side edge flange that extends to the free end side of the lid body And, from the arc corner portion perpendicular to both of the short side edge flanges, it is depressed upward by a certain fixed depth corresponding to the corner fitting convex wall,

Both long side edges are used as a rail form that extends along both short side edge flanges of the lid body so that the fitting concave step surface on the lid side that can be fitted with the above-mentioned fitting convex step surface on the container body side during lid application. Until reaching the arc corner part perpendicular to the flange, it is depressed upward by a certain fixed depth from the above-mentioned palmar plane,

Only two pairs of egg storage recesses lined up on the short edge rim flange side of either one of the lids, as the flat labeling surface on which the standing wall of the boundary part is for attaching the barcode label,

The distance between vertical center lines in the adjacent egg storage recesses is the long side, and the dimension from the above-mentioned palm plane to a height level that is lower than the flat top surface of the partition lattice wall by a certain level is shortened. While forming in a nearly rectangular shape as a side,

The flat top surface, which is at a height level that is lower by a certain level, is set so as to function as a recessed step surface for the egg storage recess on the side of the upper packaging container to be stacked.

Further, in claim 2, the short side of the labeling surface of the lid body is at the same height level as the flat top surface of the partition lattice wall from the fitting concave step surface in the rail form, regardless of various sizes of the egg packaging container. Further, it is characterized in that the dimension up to the height level lowered by a certain step is set to be constant.

Furthermore, in claim 3, the long side of the labeling surface is set to a size within a certain range of 40 mm to 45 mm, and the constant step which is lower than the flat top surface of the partition lattice wall is set to a size of 2 mm. It is characterized in that the short side of the affixing surface is set to a dimension of at least 13 mm.

  According to the above configuration of claim 1, only two pairs of egg storage recesses arranged on the short side edge flange side of the lid body are for the standing wall surface of the boundary portion to attach the barcode label. As a flat labeling surface, the distance between vertical center lines in adjacent egg storage recesses is the long side (width), and the flat top surface of the partition lattice wall that partitions the egg storage recesses Because it is formed in a nearly rectangular shape with a short side (height), the dimension up to a height level that has been lowered by a certain level difference, the barcode label affixed to the label affixing surface can be Easy and reliable visual inspection, as a result, egg sorting containers at the GP center, inspection work in the state of being loaded on the roll inner, bar code reading work at mass retailers Etc. there is no mistake conveniently carried out effect.

  Moreover, since the flat top surface at the low height level of the labeling surface is set to form a relief concave step surface for the egg storage recess on the upper packaging container side to be stacked, the upper packaging By placing only one of the egg storage recesses located on the short-side edge flange side of the container on the escape recess step surface at the lower height level as shown in FIGS. There is also an effect of preventing the upper packaging container from becoming an excessively inclined posture, maintaining a sufficient degree of biting with the lower packaging container, and obtaining a stable stacked state that does not collapse and a packaging state with less dead space. .

Furthermore, when the egg packaging container is covered, the rail-like fitting concave step surface on the lid side and the corresponding rail-like fitting convex step surface on the container body side are fitted, and the peripheral partition convex wall on the lid side is also fitted. The convex rib protruding from the receiving inclined surface and the convex rib receiving concave groove notched in the insertion inclined surface of the peripheral partition convex wall on the container body side are fitted, and the crescent corner fitting concave step surface on the lid side And the corresponding crescent-shaped corner mating convex wall on the container body side can be mated, and the superimposing and comprehensive mating action can provide a hermetically sealed seal. Further, while maintaining the fitting state in which the long edge fringing flanges on the free end side are not misaligned, there is also an effect that the sealing action such as automatic mechanical heat sealing and tape sealing can be performed quickly and accurately.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 11 show a so-called regular-type 10 eggs packaging container, and (A) and (B) are the container body and lid. It is a pair with the body, and is vacuum formed integrally and continuously from polyethylene terephthalate, polystyrene, and other thin transparent or translucent thermoplastic sheet materials as substantially rectangular planar contours of the same size. .

  Speaking of the specific configuration of the container body (A) and the lid body (B) formed from the plastic sheet material by attracting adsorption to a vacuum mold (not shown), (1a) ( 2a) is a parallel long edge rim flange and short edge rim flange of the container body (A), and (1b) and (2b) are parallel long edge rim flange and short edge rim flange of the lid (B). Opening and closing for half-folding with a constant band width (w) (for example, about 7 mm) as shown in FIG. 2 between the adjacent long-side edge flanges (1a) and (1b) of the main body (A) and the lid (B) It is pivotally connected via a hinge (P).

  On the other hand, the open / close hinge (P) is bent into a substantially isosceles triangle cross section in the covered state, and perforations (3) or half-cut lines are arranged in parallel along the bent ridgeline. In addition, the flat surfaces of the tear pieces (4) occupying each other are color-printed with differently colored container identification marks or tear direction guide arrows depending on various sizes of the eggs (E).

  In addition, the size of the egg (E) is generally classified into four types, LL, L, M, and MS, and a single color such as red, orange, green, and blue, which is different for each size, is applied. It has come to be.

  When the egg (E) is stored in the packaging container by the automatic packaging machine for the egg (E) and folded from the opening hinge (P), the length of the container body (A) and the cover body (B) The side edge flanges (1a) and (1b) and the short side edge flanges (2a) and (2b) are brought into full contact with each other in the palmed state as shown in FIGS. (L-L) shows the entire flat palm plane.

  And since the long edge fringe flanges (1a) (1b) on the free end side facing the open / close hinge (P) are sealed in a close contact state as a heat seal in a heat sealer or a tape seal in a tape sealer. is there. (5) illustrates the tape-sealed strip-shaped adhesive tape. The user who has purchased the egg (E) releases the egg (E) from the packaging container by unsealing the tightly sealed state or tearing the tear piece (4) of the opening / closing hinge (P). be able to.

  In that case, the long side edge flanges (1a) and (1b) of the container body (A) and the lid (B) have a wide width (for example, about 8 mm) on the free end side, and an open / close hinge parallel thereto. Although the difference in the width on the (P) side is changed as a narrow width (for example, about 1.5 mm), the long-side edge flange (1a) between the container main body (A) and the lid body (B) even if the width is narrow ) (1b) are in full contact with each other, so there is a risk that insects and other foreign substances may enter the inside of the packaging container from the open ends of the open / close hinge (P) that bends into an approximately isosceles triangle when the lid is applied. And the hygienic condition of the eggs (E) is maintained.

  (6a) and (6b) are respectively shown inside the rectangular sections in plan view surrounded by the rim flanges (1a), (1b), (2a) and (2b) of the container main body (A) and the lid (B). 1 to 5 is a partition lattice wall arranged in a vertical and horizontal orthogonal relationship, and is almost constant depth (d1) (h1) in the up and down direction opposite from the above-mentioned palmar plane (LL). It extends to a depressed height position (for example, about 17 mm). Moreover, the bottom surface of the partition lattice wall (6a) on the container body (A) side and the top surface of the partition lattice wall (6b) on the lid (B) side are both flat surfaces.

  (7a) and (7b) are lattices in which adjacent eggs (E) do not contact each other through the partition lattice walls (6a) and (6b) where the container main body (A) and the lid (B) correspond to each other. A plurality of egg storage recesses divided into states (in the example shown, 10 in 5 × 2 rows), as shown in FIGS. 3 to 5, the egg storage recesses on the container body (A) side ( Compared to the case where 7a) is depressed deeply by a certain depth (d2) (for example, about 39 mm) downward from the palmar plane (LL), the egg storage recess (7b) on the lid (B) side Is recessed from the joint plane (LL) upward by a certain depth (h2) (for example, about 29 mm).

  Moreover, the egg storage recesses (7a) and (7b) of the container body (A) and the lid body (B) are almost truncated cones or bowls that gradually become rounder in the opposite vertical direction. It is shaped like a regular octagonal pyramid, but it has a relatively large steeply inclined wall surface (8a) (8b) with a relatively large angle at which the base end side from the midway part that sinks in the vertical direction intersects the above-mentioned palmar plane (LL) Similarly, the remaining tip side from the midway portion is a moderately inclined standing wall surface (9a) (9b) having a relatively small angle intersecting the above-described palmar plane (LL), and the midway portion is in a refracting state.

  As a result of such superimposing and comprehensive fitting, there is no risk of relative displacement between the container body (A) and the lid (B), and the long edge that extends to the free end side is provided. In addition to being able to smoothly and stably execute the automatic mechanical sealing action between the flanges (1a) and (1b), there is an effect that a sealed state rich in insect-proof performance at the time of covering can be secured.

  (17a) and (17b) are particle-like or satin-like uneven groups provided on both short-side edge flanges (2a) and (2b) of the container body (A) and the lid (B), respectively, and a packaging container When stacked in the unfolded state, they are prevented from sticking to each other, which helps to ensure separation one by one.

  It is limited to the portion where either one of the short side edge flanges (2a) and (2b) in the container body (A) and the lid (B) and the partition lattice walls (6a) and (6b) intersect at right angles. 2, by omitting the installation of the peripheral partition convex walls (13a) and (13b), about half occupying the proximal end side of the adjacent egg storage recesses (7a) and (7b) as two rows thereof. Each of the steep inclined wall surfaces (8a) and (8b) is continuous as flat labeling surfaces (18a) and (18b).

  That is, only two pairs of egg storage recesses (7a) and (7b) arranged on the short-side edge flange (2a) (2b) side of the container body (A) and the lid body (B) As shown in FIG. 6, horizontal wall surfaces of adjacent boundary portions are horizontal (horizontal) as flat labeling surfaces (18a) and (18b) having the same inclination angle as the steeply inclined vertical wall surfaces (8a) and (8b) on the base end side. ) Is formed in a substantially rectangular shape extending along the direction.

  On the other hand, the long side (width) (x) of the flat label attaching surface (18a) (18b) having a substantially rectangular shape corresponds to either the container main body (A) side or the lid (B) side. However, as shown in FIGS. 3 and 6, the distance between the vertical center lines in the adjacent egg storage recesses (7a) and (7b) is substantially equal to, for example, a dimension within a certain range of about 40 mm to about 45 mm. The difference varies slightly for each size (four types exemplified above) corresponding to the eggs (E) of the packaging container.

  In contrast, the short side (height) (y) of the label attaching surface (18a) on the container body (A) side is shorter than that of the container body (A) as shown in FIGS. Regardless of the various size changes of the packaging container, the dimension reaching from the fringe flange (2a) to the same depth level (DD) as the flat bottom surface of the partition grid wall (6a) is, for example, a constant value of about 20 mm. It is.

  On the other hand, the short side (height) (y) of the label affixing surface (18b) on the lid (B) side is the rail-shaped fitting recess of the lid (B) as shown in FIGS. The egg storage recess is lowered from the step surface (12b) by a certain step (h6) (for example, about 2 mm) from the same height level (ZZ) as the flat top surface of the partition lattice wall (6b). As a dimension to the same height level (HH) as the refracted middle part (boundary line) of the steeply inclined wall surface (8b) and the gently inclined wall surface (9b) forming (7b) Regardless of the various size changes of the container, by setting a constant value of about 13 mm, which is smaller than that of the container body (A) (about 20 mm exemplified above), the height difference (h6) is the back. Upper package that stacks flat top surface at low height level (H-H) Than is to function as egg receiving recess for relief put concave stepped surface of the container side (19).

  In this case, the packaging container is a so-called regular type, and as shown in FIGS. 12 and 13, the egg storage recesses (7 a) and (7 b) are alternately placed in the front-rear direction (longitudinal direction) and the left-right direction (width direction). When stacked as an occlusal misaligned state, the short side (height) of the label affixing surface (18b) installed only on the short side edge flange (2b) side of the lid (B) ( y) is a large dimension from the rail-shaped fitting concave step surface (12b) of the lid (B) to the same height level (Z-Z) as the flat top surface of the partition lattice wall (6b). Or a certain step (h6) of the recessed step surface (19) for the egg storage recess that decreases from its height level (Z-Z) is a small dimension of less than 2 mm, the upper packaging container One short edge franc in Only one of the egg storage recesses (7a) located on the (2a) side rides on the top surface of the tall escape recess step surface (19), and the remaining four egg storage recesses (7a) Sunk inside the intermediate partition column (10b), so that one short-side edge flange (2a) side of the upper packaging container has an excessively slanted posture, and the degree of occlusion with the lower packaging container is insufficient. Together, they cannot secure a beautiful and stable stack.

  However, the constant step (h6) of the escape concave step surface (19) for the egg storage recess that decreases from the same height level (ZZ) as the flat top surface of the partition lattice wall (6b) is 2 mm. If the size is too large, the short side (height) (y) of the labeling surface (18b) is limited to be so low that it is less than 13 mm. Therefore, the bar code for the labeling surface (18b) It becomes impossible to easily and accurately perform automatic mechanical application of labels, detection by detection sensors after application of labels, and barcode reading at stores.

  For this reason, the short side (height) (y) of the flat label attaching surface (18b) on the lid (B) side is the same as the flat top surface of the partition lattice wall (6b). Decrease by a certain level difference (h6) of about 2 mm from the height level (Z-Z), and always ensure at least 13 mm at the same time, and the flat top surface at the reduced height level (H-H) It is set so that it can function as an escape concave step surface (19) for the egg storage recess on the side of the upper packaging container to be stacked.

  In the case of the illustrated embodiment, flat labels parallel to the vertical positional relationship at the time of lid application to the same short side edge flange (2a) (2b) side of the container body (A) and the lid body (B). Affixing surfaces (18a) and (18b) are provided, and only a label affixing surface (18b) on the lid (B) side is a rectangular (about 10 mm) extending in a slightly smaller horizontal (horizontal) direction. × about 38 mm) barcode label (C) is affixed, but the label affixing surface (18a) on the container body (A) side is omitted, and the label affixing on the lid (B) side is applied. It is sufficient to form only the attachment surface (18b).

  In addition, in the illustrated embodiment, a regular type of egg wrapping container with 10 pieces in total (5 pieces × 2 rows) has been described as a representative example, but the correspondence between the container body (A) and the lid body (B) is matched. A plurality of egg storage recesses (7a) and (7b) in a partitioned lattice state are stacked in an occlusal state in which the phase changes alternately in the front-rear direction (longitudinal direction) and the left-right direction (width direction) one by one. As long as it is a regular type egg packaging container that will be produced, it will contain a total of 4 pieces (2 pieces x 2 rows) or a total of 6 pieces (3 pieces x 2 rows), a total of 8 pieces (4 pieces x 2 rows) The present invention can also be applied to a total of 12 pieces (6 pieces × 2 rows).

  In any case, the label attachment surface (18b) on the lid (B) side is the same as the steeply inclined standing wall surface (8b) forming the proximal end side of the egg storage recess (7b) as described above. Since it is a flat surface with an inclined angle, it will be tilted upward when the lid is applied. As a result, anyone can easily and surely check and check the barcode label (C) affixed here. Useful for sorting work and bar code reading work at dealers.

  Furthermore, in the packaging container of the illustrated embodiment, a rail that sinks upward by a certain depth (h4) from the above-mentioned palm plane (LL) along both short-side edge flanges (2b) on the lid (B) side. Since the fitting concave step surfaces (12b) are arranged in a row, the short side (height) (y) of the rectangular label attaching surface (18b) is set to a height from the fitting concave step surface (12b). Measured as the height dimension, and the preferable numerical values were explained, but the fitting concave step surface (12b) on the lid (B) side and the corresponding fitting convex on the container body (A) side useful for achieving the insect-proof effect Installation of the step surface (12a) may be omitted, and in the case of the omitted packaging container, the short side (height) (y) of the labeling surface (18b) is the palm plane (LL). Measured as the height dimension from the above, the dimension up to the height level (Z-Z) is about 17 mm, The size of the remote to a certain step (h6) only reduced the height level (H-H) may be set to about 15 mm.

  The barcode label (C) also has a rectangular shape extending in the horizontal (horizontal) direction, and as shown in an enlarged view in FIG. In addition to (20), the remaining half (left half) has symbols (for example, 10H-M) (21) and colored color (for example, green) (22) indicating the various sizes of the packaging container, and letters indicating the material ( For example, PET (23) is preferably printed.
