Description

  The present invention relates to a packaging container for stackable articles, and more particularly, includes a locking means that can be stacked in a state in which no articles are accommodated and that prevents a lid from being opened during transportation or storage. Related to the container. In addition, the present invention is capable of stacking and is equipped with a safe locking means to safely package individually fragile items such as eggs, and prevent the contents from flowing out when the items are damaged. It relates to a container that can be used.

  A pulp mold technique is known as a method for manufacturing a paper container for individually packaging a fragile article such as an egg. When an egg packaging container (egg pack) is manufactured by the pulp mold technique, the lid can be integrally formed when the container is small, but when the container is large, it is difficult to integrally mold the lid. For example, a large container for storing 30 eggs is difficult to form integrally with the lid, and uses a lid made of another synthetic resin, so it is not environmentally friendly. Small egg wrapping containers for wrapping about 10 or 20 eggs can be integrally molded with a pulp mold technique, but the trademark or manufacture of articles contained on the container lid surface. It is difficult to directly perform printing for displaying a vendor or the like. Therefore, since the label for displaying the origin printed separately on the surface of a container is affixed, manufacturing cost rises. Moreover, when manufacturing a packaging container using a pulp mold technique, the drying process for drying the shape | molded container is required, and much energy is consumed for drying.

  In order to solve the problems of the paper container manufactured by the pulp mold technology described above, a container that can wrap a paper board such as cardboard and wrap eggs is disclosed in US Pat. No. 4,462,537. U.S. Pat. No. 4,462,537, FIGS. 8 and 9 show an egg wrapping container made of corrugated cardboard or paperboard, which has the advantage that it can be printed on the outer surface of the box. Among the containers illustrated in US Pat. No. 4,462,537, the embodiment shown in FIG. 9 relates to the container of the present invention. However, the container of the embodiment shown in FIG. 9 is not stacked because the side walls of the container interfere with each other. In order to laminate the container of the embodiment shown in FIG. 9, a part of the side wall to which the inclined wall at the center of the container is bonded must be removed. The strength of the container is weakened. If the containers cannot be stacked, the container is expensive to store and transport. In addition, it is difficult to utilize the conventional egg wrapping apparatus because the containers cannot be supplied in a stacked state to the egg wrapping apparatus installed in the conventional chicken farm.

  A paper packaging container for solving the problems of US Pat. No. 4,462,537 is disclosed in US Pat. No. 7,188,727 B2. The container shown in FIG. 3 of US Pat. No. 7,188,727 B2 is made of cardboard or paperboard, can be printed on the container, and another container is placed on top of a container with the container lid open. There is an advantage that can be laminated.

  The container disclosed in US Pat. No. 7,188,727 B2 includes a cover, a bottom part, and an insert. A recess is formed at the bottom, and the insert is erected on the bottom around the recess, and the bottom is defined by a plurality of storage cells for storing articles. The insert is made by folding a developed view of the paperboard with a fold line so as to have a through hole in an upright state. Therefore, the container insert placed in the lower part of the container with the cover opened is inserted into the insert through the recess of the container and laminated.

  However, all the articles placed in the storage cells defined by the inserts were stored when a part of the article was supported by the side walls and an impact was applied to the side walls during storage or transportation. There is a problem that the article cannot be sufficiently protected. In addition, the stored article is in direct contact with the bottom plate of the container, and the stored article cannot be sufficiently protected from the impact from the bottom. In addition, there is a problem that it is difficult to automate the process of folding an insert having a complicated structure with many fold lines, and the process of bonding the folded insert to the bottom is difficult to automate by the machine. That is, since the structure of the container is complicated, mass production is difficult and the price is high.

  There is a need in the market for containers that can package fragile items, such as eggs, more safely and cheaply. In response to such market needs, the inventors of the present application have filed two patents in Korea under the title of a packaging container for fragile articles. One is patent application number 10-2011-0112570 (filing date 2011.10.13), and the other is patent application number 10-2011-0112229 (filing date 2011.11.11). is there. All the technical matters disclosed in the above two patent specifications are combined as a part of this specification.

  The packaging containers disclosed in the above two patents include a storage portion, a corrugated insertion portion that is inserted into and combined with the storage portion, and a lid portion. The accommodating part includes a bottom plate and a plurality of inclined side walls extending from the end of the bottom plate so as to be inclined upward.

And supporting side walls inclined in opposite directions. Each groove of the corrugated insertion portion includes a flat groove bottom, and each groove bottom is coupled to the bottom plate of the housing portion. In addition, the bottom plate of the housing part is formed with a laminated through-hole for removing the gap between the coupled groove bottoms and laminating. In addition, ribs are formed between the stacked through holes formed in the bottom plate of the housing portion. The groove bottom portion of the corrugated insertion portion is coupled to the rib. Therefore, when laminating a plurality of containers, the land of the corrugated insertion portion of the container placed in the lower portion passes through the laminated through hole and is disposed in the lower portion of the land of the container placed in the upper portion. And no interference from the land. Further, the corrugated insertion portion is separated from the inclined side wall of the housing portion by a certain distance and is coupled to the bottom plate of the housing portion. Therefore, when a plurality of containers are stacked, there is no interference between the land of the corrugated insertion portion of the container placed in the lower portion and the inclined side wall of the accommodating portion placed in the upper portion.

  The containers disclosed in the above-mentioned two patents developed by the inventors of the present invention are designed to accommodate products in grooves. The product accommodated in the groove is supported by a pair of opposing support side walls that form the groove so as not to contact the bottom plate, the inclined side wall, and the cover portion of the lid. Therefore, the containers disclosed in the above-mentioned two patents can protect the article safely by preventing external impact applied to the container from being directly applied to the accommodated article.

  However, the containers disclosed in the above two patents have the following problems. First, when a fragile article such as a glass bottle containing eggs or liquid is damaged by an impact, the contents may flow out to the outside through the stacked through-holes of the containing portion. Secondly, the structure for fastening the lid to the accommodating portion is fragile, and there is a possibility that the article opened and accommodated during transportation or storage may be damaged.

  An object of the present invention is to provide a container having a new structure for solving the above problems.

  The first object of the present invention is to allow lamination, prevent the lid from being opened during storage and transportation of the container, and safely protect the contained articles, while at the same time easily opening the lid, It is to provide a container having a new structure capable of taking out contained articles.

  The second object of the present invention is to provide a new structure capable of safely protecting a fragile article that can be laminated, and at the same time preventing the contents from flowing out when the contained article is damaged. Is to provide a container.

  The packaging container for stackable articles according to the present invention includes an accommodating portion, a lid portion, and a lock portion. The accommodating portion includes an accommodating bottom plate and a plurality of inclined side walls extending so as to be inclined from the end of the bottom plate in order to limit the accommodating space inside. The lid includes a cover plate and a plurality of inclined side walls extending so as to be inclined from the end of the cover plate in order to limit the accommodation space in the upper part. The lock portion includes a lock bottom plate and a plurality of inclined side walls extending so as to be inclined from an end of the bottom plate in order to limit a housing space inside.

  Further, the container according to the present invention is accommodated by being inclined so that the inclined side wall of the accommodating portion, the inclined side wall of the lid portion, and the inclined side wall of the lock portion are opened toward the upper part with substantially the same inclination. Limit space. In addition, the container according to the present invention rotates the lid connected to the inclined side wall of the storage unit, covers the upper part of the storage unit, rotates the lock unit connected to the inclined side wall of the cover, and stores the container. The part is inserted into the accommodation space of the lock part and restrained so that the lid part does not open. That is, the accommodating part and the lock part are arranged on both sides of the lid part, the adjacent inclined side wall of the accommodating part and the inclined side wall of the lid part are connected, and the adjacent inclined side wall of the lid part and the lock are connected. The inclined side wall of the part is connected. Further, the accommodating portion is inserted into the accommodating space of the lock portion so that the inclined sidewall of the accommodating portion and the inclined sidewall of the lock portion are in close contact with each other.

  Further, when the lock portion is rotated around the inclined side wall connected to the lid portion, the end portion of the inclined side wall of the lid portion is formed so as to be in contact with the end portion of the inclined side wall of the lock portion. When the lid is closed, the inclined side wall of the lid portion is in contact with the inclined side wall of the lock portion, and the end surface of the inclined side wall of the lid portion is in contact with the end surface of the inclined side wall of the lock portion. It is preferable to protect the contained articles.

  The receiving part, the cover part, and the lock part can be made by folding a paper board. The paper board includes a cardboard and a corrugated paper board. The paper board can also include a layer coated with a synthetic resin or chemical to improve the properties of the paper surface. When manufacturing the housing part, the cover part, and the lock part with a paper board, it is possible to create a development view in which the inclined side walls are connected by a single paper board, and to form a fold line at the connection part to form it integrally. . The container according to the present invention can also be manufactured using materials other than paper board. For example, the film can be produced by vacuum molding or by injection molding a synthetic resin.

  When the container is opened in order to take out the articles stored in the container, the lock part and the cover part must be rotated in reverse directions around the connected inclined side walls. In this case, the contents stored in the container may overflow. Therefore, it is preferable to form a cutting line on any one or both of the inclined side walls on both sides of the lid so that only the lid of the container is rotated and the contents of the container can be taken out. When a cutting line is formed on the inclined side wall of the lid connected to the container when the user takes out the contents from the container, a force is applied to the cutting line to cut the inclined side wall, and the lid and the container When the connection is cut, the lid part is rotated around the inclined side wall connected to the lock part, and the container can be easily opened to take out the article stored in the storage part.

  In addition, the container according to the present invention may further include a corrugated insertion portion that is inserted into and combined with the accommodating portion in order to safely store individually fragile items such as eggs. The corrugated insertion portion includes lands, grooves formed on both sides of the lands, and support side walls that are connected to adjacent lands and grooves and are sequentially inclined in opposite directions along the wave traveling direction. Each groove of the corrugated insertion portion includes a flat groove bottom portion, and each groove bottom portion is coupled to the bottom plate of the housing portion. Moreover, the lamination | stacking through-hole is formed in the bottom plate of an accommodating part so that a container can be laminated | stacked. The laminated through-hole is formed by removing the gap between the bottom of the groove coupled to the bottom plate. When the plurality of containers are stacked, the land of the container disposed in the lower part is inserted into the stacked through hole.

  The corrugated insert can be made by folding a paper board. The paper board includes cardboard and corrugated paper board. The paper board can also include a layer coated with a synthetic resin or chemical to improve the properties of the paper surface. The corrugated insert includes a plurality of agrooves formed by two fold lines. Accordingly, each groove of the corrugated insertion portion has a flat bottom portion and is easy to bond. The wave of the waveform insertion part is a wave that starts from the groove bottom and ends at the groove bottom. The corrugated insert can also be manufactured using materials other than paperboard. For example, the film can be produced by vacuum molding or by injection molding a synthetic resin. In particular, the corrugated insertion portion may be any material as long as it has the same elasticity as paper.

  A rib is formed between the stacked through hole formed at the bottom of the accommodating portion. The groove bottom is coupled to the rib. Each groove bottom of the corrugated insert can be joined to the corresponding rib with an adhesive or joined with a staple. Further, a projection can be formed at the bottom of the groove, and a groove for inserting the projection can be formed at the bottom of the accommodating portion, and can be joined by being sandwiched without using an adhesive. The laminated through-hole formed in the bottom plate of the housing portion communicates with the space formed by the adjacent inclined support side wall extending from the groove bottom portion coupled to the rib. The corrugated insertion portion is separated from the inclined side wall of the housing portion by a certain distance and is coupled to the bottom plate of the housing portion. In addition, the inclined side walls of the housing portion are formed so as to incline upward from the bottom plate, and the inclined support side walls on both sides of the corrugated insertion portion are spaced apart from the inclined side walls by a certain distance. Therefore, when one container is stacked on top of another container, the land of the container located at the bottom extends from the bottom of the groove connected to the rib through the stacking through hole of the bottom plate of the container positioned at the top. It can be stacked by being inserted into the space formed by the adjacent support side walls. That is, interference due to the inclined side walls of the accommodating portion and interference due to the land of the corrugated portion do not occur when stacking.

  It is preferable that the stackable container according to the present invention accommodates a fragile article between the supporting side walls of the corrugated insertion portion (groove between the lands). The supporting side wall facing the corrugated insertion portion is tapered and inclined so that the width becomes narrower toward the bottom, and the article accommodated between the facing supporting side walls does not contact the groove bottom of the groove. Therefore, the impact from the bottom of the container is not directly transmitted to the accommodated article. Further, the inclined side wall extends upward so as to be inclined from the bottom plate of the accommodating portion, and the article accommodated in the container does not contact the inclined sidewall of the accommodating portion. Therefore, the impact from the inclined side wall of the housing portion is not directly transmitted. Therefore, a fragile article such as an egg housed in the groove of the corrugated insertion portion can be safely stored. Further, in the packaging container for stackable articles according to the present invention, the accommodating portion in which the laminated through hole is formed is inserted into the accommodating space of the lock portion. Therefore, even if the accommodated article is damaged and the liquid flows out from the laminated through hole, it is prevented from flowing out by the lock bottom plate below the laminated through hole. The lock part in the stackable container according to the present invention functions as a lock means for preventing the lid from opening, and at the same time, the container such as a glass bottle containing eggs or liquid is broken and the contents are damaged. It serves as a leakage prevention function for preventing the storage portion from flowing out of the laminated through hole.

  Moreover, it is preferable that the packaging container of the article | item which concerns on this invention forms an inclination so that the width | variety may narrow along the land direction direction on both sides of the wave width direction of the support side wall of a waveform insertion part. When an inclination is formed on the supporting side wall of the corrugated insertion portion, it is easy to insert the corrugated insertion portion into the stacking through hole of the container stacked on top.

  In addition, when the height of the land of the corrugated insertion portion is higher than the height of the inclined side wall of the housing portion and the lid portion is closed, the top portion of the land of the corrugated insertion portion contacts the cover plate of the lid portion and is accommodated. It is further preferred to protect the finished article. The plurality of lands formed in the corrugated insertion part may be formed by two fold lines so as to have a flat top portion, or may be formed by one fold line so as to have an acute angle. When the top of the land is formed to have an acute angle, the container can be made more compact by reducing the length of the container in the wave traveling direction.

  In the present invention, when the fold line formed on the paper board is sequentially folded to form the groove and the land, the wave traveling direction (direction of arrow A in FIG. 1) is the direction from the land to the adjacent land (adjacent from the groove). The direction of the wave width (the direction of the arrow B in FIG. 1) means the width direction of the waveform insertion portion (the length direction of the groove or the length direction of the land).

  In the container according to the present invention, when a plurality of articles are stored in the groove of the corrugated insertion portion, in order to prevent the articles stored in the groove from flowing in the wave width direction and colliding with each other and being damaged, A buffer plate can be installed. In order to install the buffer plate in the corrugated insertion portion, an incision is formed in each land of the corrugated insertion portion in the wave traveling direction. A buffer plate extending along the wave traveling direction is inserted into each incision portion of the waveform insertion portion to divide each groove.

  Moreover, the packaging container of the fragile article according to the present invention has an article between the corrugated insertion portion and the inclined side wall of the housing portion facing the both side support side walls in the wave traveling direction when the corrugated insertion portion has only one land. Can be accommodated. In addition, even when there are a plurality of lands, articles can be accommodated between the inclined side walls of the accommodating portion facing the both side supporting side walls in the wave traveling direction of the corrugated insertion portion, and the packaging equipment can be reduced. When the article is accommodated between the both side support side walls of the corrugated insertion portion and the inclined side wall in the wave traveling direction of the accommodating portion, the wave traveling direction of the accommodating portion is reduced in order to mitigate the impact applied to the inclined side wall from being directly applied to the article. And a pair of support wings extending from the both side inclined side walls in the wave traveling direction of the lid. The support wing part of the housing part is folded toward the housing bottom plate, the support wing part of the lid part is folded toward the cover plate, and the article is accommodated between the both side support side walls of the corrugated insertion part and the folded support wing part. In this case, the impact applied to the inclined side wall by the support wing portion is mitigated from being directly transmitted to the article.

  Further, in the container according to the present invention, when an article having a circular or elliptical cross section such as an egg is accommodated between adjacent support side walls, the accommodated article is prevented from flowing in the wave width direction. A through hole or a cutting line for inserting a part of the article respectively accommodated in the supporting side wall facing the corrugated insertion portion can also be formed. In addition, each support wing portion can be formed with a through hole into which a part of the accommodated article is inserted. Also, each support wing part of the housing part is bent so that the end part comes into contact with the bottom plate of the housing part, each support wing part of the cover part is folded, and the end part comes into contact with the cover plate of the lid part. Thus, the article can be safely supported such that the supporting wing portion supporting the article maintains a predetermined inclination.

  The stackable container according to the present invention includes a storage portion, a lid portion, and a lock portion, and the storage portion is inserted into the lock portion so that the inclined side wall of the storage portion is in close contact with the inclined side wall of the lock portion. It functions as a lock to prevent the lid from opening and prevents the lid from opening during storage or transportation. In addition, the lid of the container can be easily opened by cutting a cutting line formed in the lid.

  Moreover, the container which can be laminated | stacked which concerns on this invention accommodates articles | goods so that the accommodated articles | goods may not contact the accommodation baseplate of a container, a cover plate, and a side wall, when the waveform insertion part is further included. Therefore, when the container receives an impact from the outside, it is possible to prevent the impact from being directly transmitted to the accommodated article, and safely store the fragile article.

  In addition, when the stackable container according to the present invention is manufactured with paper, it has an advantage that it is environmentally friendly in the manufacturing method, saves energy, and can be printed directly on the surface of the container, compared to a container manufactured with pulp mold. is there.

  In addition, the container according to the present invention is capable of being stacked, but at the same time, when an article containing liquid is damaged, the liquid is prevented from leaking out of the container by the lock bottom plate of the lock portion. Further, the container structure is simple, mass production is possible, and an inexpensive packaging container can be provided.
