Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to packaging of eggs, fruits, etc., and more specifically to a box or carn for packaging these items, comprising a base molded body having a recess formed therein to receive the above-mentioned items. , this relates to a box or carton of the type consisting of a cover or lid fixed to its open top for closure. The base molding may be molded of paper pulp or plastic. For example V-) In the conventionally known egg box of the above type, the base molded body (hereinafter referred to as the base), which is rectangular in plan view, is made higher than the height of the eggs stored in the article receiving recess. ing. It is molded from clear plastic and closed by a separate rectangular, flat cardboard lid, usually located at about the same height as the edge. Such a combination is particularly advantageous for the packaging of egg-like foods, since the intricately assembled base can be easily molded, the contents can be visually inspected, and the
For one thing, advertisements and other information needed by the suppliers of these foods can be easily printed on them.
However, a problem with known egg boxes is that when closing and fixing the base with a separate lid, it is difficult to achieve sufficient structural integrity, especially at the edges of the lid. , such integrity is an important requirement so that no damage to the contents occurs when these boxes are stacked for transportation, storage, and display purposes.

In one example of an egg carton of the above type described in GB Patent Specification 11 207!618A, the cardboard lid is latched to a post rising from the base to keep it closed. This lid has a hanging piece shaped like a pin, which is inserted into a hole in the top of the column. However, with Jin's structure, it is difficult to fix. Furthermore, since the area on which the edge of the lid rests is a narrow glue-like area formed around the edge of the base, no matter how much the support is used to support the lid in the correct position, the edge of the lid can be held securely. Instead of being supported, it will bend and sag into the base, and its weight will risk damaging the contents, especially when the boxes are stacked.

On the other hand, British patent specification no.
Moreover, this housing is overlapped with both ends of the opposing cane in the longitudinal direction of the base. Advertising and other information can be printed on this flap piece, and even when the boxes are stacked for storage or display, the information can be seen from the 91 side of the base. fart,
For example, it is fixed and kept closed using adhesive sound. According to this configuration, the lid is supported sufficiently firmly and there is no risk of damaging the contents even if the boxes are stacked, but on the other hand, it is difficult to open the lid, and once it is opened, it cannot be closed again. It's not easy.

In addition to the above, examples of prior art forming the technical background of the present invention include British Patent Specification No. 284162 and British Patent Specification No. 94748.
No. 1, US Pat. No. 1,198,177! , No. 8498
164'8- and No. 8767109, as well as French Patent Specification No. 21518564J8.

Therefore, the object of the present invention is to eliminate the drawbacks of the above-mentioned known types of packaging boxes, and
To provide a packaging box or carton having a structure in which a lid is firmly supported by a base in a closed state. In addition to the above-mentioned characteristics, another object is to provide a packaging box or carton which is easy to fix to close it, can be opened freely, and can be easily re-fixed if necessary. It is in.

This invention consists of a base as a mature product having a recess formed therein for storing an article, and a lid that protrudes upward from the base and is fixed on the open top of the base. In the box configured to close the base, the lid has a substantially flat top plate.

The top plate has nine opposing wall portions depending from at least the edges of the chamber, these wall portions projecting downwardly into the top of the base and juxtaposed with the upright wall of the outer sludge. support means configured to be in a juxtaposed state, with at least one of said wall portions having its bottom end below the periphery of said base and projecting inwardly from said juxtaposed walls; It exists in packaging boxes or cartons for eggs and fruits, which have a structure that is supported on the top, and the edge of the lid near the K is supported. .

The base and the lid may be rectangular in plan view like conventional ones, and the base may have nine recesses for storing articles arranged (transposed) in parallel to each other. The lid has a hollow shape, and its flat top (hereinafter referred to as the top plate) is a wall portion (hereinafter referred to as the top plate) that hangs down from a pair of opposing side edges and end edges.
It may also have a shape (hereinafter referred to as a flap).

All of the four flaps may project downward and enter the upper part of the base, and at least one pair of these flaps may have their bottom ends supported by support means within the base. .

- In the configuration 1, each of the two pairs of flaps has its bottom end supported by the support means.

Alternatively, one pair of the two pairs of flaps may be supported by the peripheral edge of the base, thereby sufficiently supporting the chain volume plate.

Although the preferred a* embodiment of the invention is configured to be completely removed from the base upon unpacking, in other embodiments, a pair of flaps projecting downward into the base may be removed from the base. It is fixed to the outer circumferential wall of the base in the parallel configuration 1 using adhesive T-, and when unpacking and closing IIAK, the Np of this fixed flap is fixed.
The body is articulated and connected to the base.

If the lid is hollow and rectangular, each of the four flaps depending from the flat top plate may be simply foldable and expandable, or some or all of the flaps may be attached to adjacent corners. The corners may also be joined together with adhesive or the like.

K, which fixes the lid in the closed position, has a stopping protrusion in the form of a protrusion, tongue, etc. that protrudes inward from the outer circumferential wall of the base, and an opening or elongated hole provided in the lid flap adjacent to this. It is possible to adopt a configuration in which the two parts are engaged with each other. In the case of a structure that can be completely removed from the W body sound base, the protruding piece is provided with at least one pair of opposing JilK protrusions on the outer periphery of the base, and engages with the opening or elongated hole of the lid flap adjacent thereto. It would be convenient if you let them. Alternatively, at least one notch 1 is provided at both opposite ends of the lid flap! It is also possible to have a structure in which a locking protrusion is formed on the base corner and engaged with a locking protrusion on the corner of the base adjacent to the protrusion.

As a support means for supporting the lid flap (lower end),
It is advantageous to use a shelf-like portion at the upper end of a protuberance formed in the outer circumferential wall of the base between the recesses for storing companion articles and connected to the outer circumferential wall of the base. The center of the top plate of the lid body can be supported by a column that stands higher than the outer peripheral edge of the base from behind the rows of these recesses.

In one embodiment, the height or depth of the base is lower than the article to be accommodated in the recess, and the lid is raised from the base to enclose the top of the article. For example, the base of the egg box according to the present invention is approximately 8/4 of the height of the eggs stored therein, and the hollow lid body is shaped to cover the top 1/4 of the eggs. . The columns between the rows of recesses for storing articles may stand up at the same height as the periphery of the base, or even higher than this, to support the center of the lid.

In another embodiment, the height or depth of the base is set 4 times higher than the article to be accommodated in the recess, and the top plate is flush with the periphery of the base when the lid is closed. The structure is similar. In this case, the center of the corpus luteum may be constructed without any support, and some or all of the supports between the rows of recesses for storing articles may be lowered below the base, or may be omitted altogether to facilitate the removal of articles from the base. It is also possible to take the following structural form.

An embodiment will be described below with reference to Figure io, in which similar members are denoted by the same reference numeral V.

The egg boxes shown in Figures 1 to 8 are made of plastic and paper.
21, both of which are filled rectangles in plan view. The base (1) may be integrally molded from a plastic sheet. Side light tf, 11 impact polystyrene V-) t-Hydraulic or vacuum forming is advantageous.

If eggs are to be packed, it is preferred that the eight bases (1) be molded as an integral unit, in which case an edge cutter close to the base is interposed between them and a web of good plastic is formed. 111, each housing 6 eggs by cutting along the kernel web.
! ! K-shaped for easy separation into 8 bases. Since each base is identical, only one is shown in its entirety and will be described in detail below.

The base (1) has six depressions (4) that receive eggs.

These are arranged in two mutually parallel rows along the length of the base, while the base is provided with side walls and edges surrounding the rows of recesses.

The height and depth of this base is slightly lower than the height of the egg to be stored there, and the height of the base is slightly lower than the height of the egg that should be stored there.
) protrudes upwards from the base.

The side walls and edges of the base form the recess (4) into which the egg (4) is placed. +61, fil and a hollow connecting partition J1 joining these end walls and extending between them! It's a cry. Nine hollow pillars (1) protrude upward from between the two rows of recesses, and are located at the centers of the four adjacent recesses, while hollow pillar-like protrusions +81, (9+ is formed between the recesses in the side wall and end wall of the base, and protrudes upward from the above-mentioned connecting partition wall. The shape should be approximately ``partial oval.'' The outer surface of each recess is formed with an upwardly extending hollow rib ring, which strengthens the recess and protects it from blows or impacts from couples. It is #I shock material that protects eggs'fr.

The closure of each recess has a hollow boss formed on its inside which serves to strengthen the closure by acting as a cushion to protect the bottom of the egg.

The central pillar (1
) has a flat upper part 1iii to support the top plate of the lid body.
It is 1141. The strut-like protrusion formed on the base am and the end wall +81, (91 also has a flat upper part m (1
It is marked @, and is slightly lower than the periphery of the base so that it functions as a shelf for supporting the lid, as will be described later.

Opposite end of the base 1! Projecting inwardly from the fil and forming the same plane as the periphery are the retaining devices for fixing the lid, and these are in the form of hollow protrusions or protrusions.

The shelf-like flat l- of the protrusion (9) formed with the end i1 trap is located directly below the lid fixing protrusion, and has a shape that provides a shoulder (+7) on the outer surface of the end wall for stacking. and cooperates with the protrusion of another box of the same shape when the base of the other box is fitted into the base of the figure. When packing, storing, transporting, or feeding into an automatic egg packing machine, the plurality of base parts are overlapped in a mating manner. In this state 1jl, the shoulder part (17) of the upper base rests on the protrusion Q of the other base when the shoulder part (17) is fitted below. This has the effect of smoothing the depolymerization and separation actions of the mechanical separation device by preventing the occurrence of "bite-in" or overcrowded mating.

On the other hand, the rectangular lid (!) has a flat top α
(hereinafter referred to as the top plate) and wall portions or flaps (hereinafter referred to as flaps) at both sides and ends, and these flaps hang down from the edges of the yXIL. Further, these flaps are integrated with the top plate 1, and are made of cardboard for the lid and bent downward along the nine-dimensional axis H.
(24 may be joined together at some of the corners.) This case can be stacked, and if necessary, when printing advertising slogans or other information, the flaps can be turned downward. This can be done when the cape is in a flat state before bending it. A long hole is punched in the fluff @ 4 at the end of the body. This is exactly the same as the fixing protrusion at the base. It should be located in a position corresponding to and should work together with it.

When the lid body (2) is fitted to the base il+ to close it, the flaps - and FA enter into the base and close the @
Wall and edge JI! The flap of the lid body is held in its bent shape 111 by these walls while taking a posture parallel to tIl and tel. And these flaps (
The lower end of 11,4 is the column-like projection t of the base side wall and end wall.
S+, rides on the shelf-like flat tiAilii carcass at the top of a and rests on it. Thus, while the strut-shaped protrusions support each edge of the lid, the top plate Q@ of the lid is supported by two struts (7) K rising from the base (Fig. 8). My body is I! 1. To be firmly supported,
Even if a series of boxes of the same shape are stacked one above the other, there is no risk of damaging the contents.On the other hand, when fitting the lid (2) into the predetermined position or posture as described above, the base end 1!
Since both the fil+ and the lid end flap- are bent and deformed, they elastically engage into the long holes adjacent to the fixing protrusions a*Vi, and as described above, It can be fixed in position. IIt- When it is necessary to open, the engagement between the projection and the elongated hole can be easily released by bending the end wall and the flap. By performing the opposite operation f$, it is easy to re-fix the lid.

The embodiment shown in Figures 4 and 5 is also similar to the first example above, except that the depth of the base of the differential molded product is slightly smaller than the height of the egg (E) to be accommodated therein. The inside of the separate hollow lid (!) made of cardboard rises above the base to cover the top of the egg. However, in this example, the support (7) at the center of the base is omitted to make it easier to take out the eggs, and the protrusion (c) for stopping 1 gA is placed at a part of the corner and extends inward from the periphery to form a companion. A part of each corner has a shoulder part for stacking that projects outward from the lower part of the periphery and is molded as part of the base.
This is to cooperate with another base O protrusion of the same shape that is fitted into the base.

In this case, since the protruding piece (c) of the upper base rests on and is supported by the shoulder (2) K of the lower part, both bases are wedged into each other, protruding, and are tightly fitted together, making it difficult to separate. This is prevented.

The lid (!) in the second embodiment shown in FIGS. 4-5 also has a flat top plate 011, and side flaps and end flaps (1111) depending from the flat top plate 011.

Both of the inner legs and cA are integrated with the top plate, and these are folded downward along the folds of the cardboard. A notch or elongated hole island is cut into the end of the rear flap IO and is located in such a way that it can cooperate with the stop tab (2) on the base. Specifically, these notches are provided at the bottom of the outwardly inclined edge (to) of the false square fob.
The edges of the end flaps are also slightly slanted outward, so that when the lid is folded, both opposing end flaps protrude slightly outwards than the vertical side flaps. I will do it. Additionally, small notches (111) are provided on both sides of the bottom edge of the end flap to connect with the above-mentioned sloping edge hem.

When the lid is fitted to close the base (1), the false flap Og! enters into the base and its @I

Retained. And the lower ends of these flaps are the base @ the upper shelf-like flatness of the strut-like protrusion tl along the wall [iI] 05
1. A strut-like projection supports the side edge portion of the body. The notch (2) is bent and elastically engages with the retaining protrusion (c) at a part of the corner to keep the lid closed.

To facilitate such engagement, the edges of the side flaps are sloped inwardly below the notch I@, as indicated by the symbol -, in the form of a guide bar. on the other hand.

Regarding the 42 end flaps of the corpus luteum in the closure operation f'1fK, it is necessary to separately and forcibly bring them into a state of engagement with the base. 1
I don't want to be able to put them in parallel.

In this state of engagement, the end flap is inclined outwardly and abuts against the slanted edge (2) of the couple foot, thereby restraining the longitudinal movement of the lid and also providing a locking protrusion. Stop the piece from separating from the notch.

Further, in this state, the horizontal bottom edge circle of the other notch (2) is supported at the periphery (131) of the base at a part of the corner and functions to support the end of the lid.

In this way, the lid body is firmly supported, so this - at-
There is no risk of damaging the contents even if they are stacked one above the other. To install this 1ift, the locking protrusion can be easily removed by bending the lid and base wall or flap,
To close the lid again, the operation is reversed, i.e., if necessary, manually apply an inward force to the end flap HK of the lid so that it engages the end wall of the base.

In the eighth embodiment shown in Figures 6-7, the base (1) is higher than the egg (lii) that is housed in the recess (4);
When the base is closed and the top plate of the lid is in the folded position, the base periphery 1 and tl are flush with each other. The shape of this base is the same as that of the second embodiment, except that the height of 9) is almost the same as the periphery. However, the lid in this example has a flat top plate. It only has a pair of lateral flaps DI hanging down from the longitudinal side edges of the α moment.Notches or slots □□□ connect with the top plate and are carved at the ends of these flaps at the Below the cutout (2), the flap C)@ is inclined inward and has the shape of an induction taper.The top plate II#A (with the flap Kl) is extended in an opposite manner and becomes the next end. When the corpus luteum of the keratin is fixed in the closed shape 9 placed over the base, these opposite ends are connected to the base periphery 1111 in the vicinity.
It has a shape that extends above.

In the closing operation, the flap contains the base film K and the false IT! The folds are kept in parallel with fIl. The lower end of the flap is supported by the flat supporting shelf tb++@ of the protrusion (8) formed along the base negative MK. The ends (to) of the top plate support each of the end edges t1 of the lid body.As in the previous embodiment, the weight bodies are thus firmly supported, so even if the boxes are stacked one above the other, the contents are not contained. There is no risk of damage to the lid. Since the flap area bends during the lid closing operation, the above notch easily engages with the stopping protrusion on a part of the corner and fixes the lid in the closed state. Even when the lid is opened, the flap area is bent. Since the lid body is easily bent, it is easy to release the engagement between the notch and the protruding piece), and if it is necessary to close and secure the lid again, the operation can be performed as described above.

Although specific embodiments have been described above, it will be appreciated that modifications may be made within the scope of the invention as set forth in the claims. - As an example, the number of eggs accommodated can be changed to 1 on each side. That is, the number and arrangement of the recesses (4) may be changed. For example, if there are 5 recesses per row, 8
For example, they may be arranged in rows for a total of 10 depressions, or arranged in eight rows with four depressions per row for a total of 12 depressions.

In order to enlarge the structure illustrated in Figs. 1 to 8,
Stopping protrusion α4 at the inner end of the box and a long hole (2) that cooperates with it
In addition, in the examples shown in Figures 4 to 7, if the number is particularly large, the pillars (7) can be inserted from the bottom of the base between the recesses for storing eggs. It can be formed into a round shape as in the first embodiment, and the center of the end of the top plate of the lid body can be supported by these supports.

In each case of FIGS. 1 to 6, the flaps (114, -) hanging down from the hollow lid (!) can be joined together using, for example, an adhesive.

Yet another modification is to permanently base the lid by joining one of the flaps, e.g. with adhesive, to the adjacent base or end wall (6j, plaster). It may be attached to.

In that case, the joined flap 01. The lid body is bent at the center of CIIt, or the flap and top plate 0
The opening/closing operation is performed by moving the lid body along the fold between the two or the flap itself K]j[in a manner similar to Klrjl, which is made parallel to the plate.
