BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper box structure capable of storing and holding stored items in a stable state.

[0002]

2. Description of the Related Art A conventional paper box body is provided with a box body comprising a front plate, a rear plate, left and right side plates, a bottom plate, and a lid plate connected to an upper end of the rear plate. Is common. In this paper box, articles are stored in the space formed by the front plate and the like.

[0003] However, according to such a paper box, the stored article is only protected around the paper material forming the box body. Therefore, the safety with respect to an external impact force is not sufficient when only the paper box is housed, and the housing state inside the paper box is often unstable. Such safety and stability are strongly required especially when the stored articles are fragile, such as ampoules and drinks, which are stored in a glass container, and further when a plurality of such containers are stored. Can be

[0004] For this reason, conventionally, in order to stabilize the stored articles in the paper box body and ensure the protection thereof, a middle frame member and a cushion member are provided between the inner surface of the paper box body and the articles. , In general.

FIG. 8 shows a conventional example in which the intermediate frame member is provided. The paper box 26 in the conventional example shown in FIG.
A seat member 28 and a holding frame member 30 are provided as middle frame members provided in the box body 27. Seat base member 2
8 and the presser frame member 30 are obtained by processing a paper material. The seat member 28 is arranged on the bottom of the box body 27. That is, a mold hole 29 is formed at a predetermined position on the upper surface of the seat member 28, and by inserting the bottom C of the article A into the mold hole 29, a plurality of articles A are erected. The article A is stored in the box body 27. Further, the presser frame member 30 is
7 near the mouth. That is, an insertion hole 31 is formed at a predetermined position on the plate surface of the holding frame member 30. By inserting the heads B of the articles A into the insertion holes 31 and pressing the upper part of the articles A, the articles A are stabilized.

FIG. 9 shows a conventional example provided with a cushion member. In the illustrated conventional paper box 32, the cushion member 34 has an outer shape of the box body 3.
3 is formed so as to be in close contact with the inner surface thereof, and a concave hole 35 conforming to the longitudinal sectional shape of the article A is formed on one surface thereof.
The article A is inserted into the recess 35 in advance, and the article A is stored in the box body 33 together with the cushion member 34 in this state.

[0007]

However, in the above-mentioned conventional paper box structure, much time and work are required for processing the inner frame member and the cushion member itself and for storing the articles in the paper box body. There are drawbacks that require special effort. Further, there is a disadvantage that the material cost and the processing cost require an additional economic burden.

Therefore, according to the present invention, the stored articles are easily broken, and even if there are a plurality of such stored articles, they can be kept in a safe and stable state without requiring a special member such as a middle frame member. Another object of the present invention is to provide a simple and economical paper box that can be stored easily and can easily and quickly store articles.

[0009]

In order to achieve the above-mentioned object, a paper box according to the present invention comprises a front plate, a rear plate, left and right side plates, a bottom plate, and a lid plate connected to an upper end of the rear plate. In a paper box provided with a box body, a connecting plate, a holding plate, and a sticking piece are respectively provided at the tip of a lid plate via a folding line, and a cutout portion is provided at an upper end of a front plate. A locking piece is protruded substantially at the center, cutouts are respectively formed at both ends of a continuous portion of the locking piece, and cut lines extending to the cutouts at the ends are provided on the front plate so as to be breakable, Further, a U-shaped notch hole protruding toward the holding plate is provided substantially at the center of a fold line connecting the connecting plate and the holding plate, and the front plate and the
A bottom plate piece is connected to the lower end of the rear plate via a fold line.
Notches are provided at the end portions of these bottom plate pieces.
One side edge of the notch is a locking edge and faces the locking edge.
A sticking tongue piece is continuously provided on the other side edge side of the notch via a folding line, and the sticking piece is stuck and fixed at a predetermined position on the inner surface of the rear plate, and the lid plate is erected. In this state, the holding plate is erected, and when the holding plate is erected, the locking piece is pushed into the notch hole, and after the pushing, the notches are locked to the edges of the notch hole. The connecting plate is brought into contact with the inner surface of the front plate to close the mouth of the box body, and at the same time, the cut line is broken, and at the same time, the holding plate is also lowered by lowering the lid plate to thereby lower the box body. The mouth can be fully opened and the front and rear plates and the bottom plate
The fold lines connecting the pieces are folded inward, as described above.
The one protruding part consisting of the bottom plate part other than the notch is

And a general paper material such as a cardboard. Further, the above-mentioned box main body, the connecting plate, the holding plate, and the sticking piece can be processed as a whole by a single paper material.

[0011] Further, the projecting configuration of the U-shaped cut hole can be obtained by forming the U-shaped central portion crossing the corresponding folding line so as to reach the pressing plate surface portion. . The U-shape of this cut line also includes a concave shape. When the cut line is formed in a concave shape, it is possible to stabilize an engagement state with a locking piece described later. In addition, when the above-mentioned sticking portion is attached and fixed to a predetermined position on the inner surface of the rear plate, and the holding plate is erected by erection of the lid plate, the protruding portion is located on the front plate side of the box body. Therefore, it is arranged in a state facing the bottom. Therefore, the notch hole is located on the side of the holding plate along the projecting portion, so that the operation of inserting the locking piece into the notch hole can be performed very easily when the holding plate is raised. it can.

[0012] In addition, the structure in which the locking piece can be pushed into the cut hole accompanying this insertion work can reduce the cut length of the cut hole.
This can be achieved by making the width slightly smaller than the maximum width of the locking piece. That is, when pushing the locking piece into the cut hole,
The locking piece deforms to reduce its maximum width. As a result, the notches on both sides of the locking piece are locked to the edges of the cut holes after the push-in. Thereby, the locking piece is strongly locked in the cut hole. In this case, in order to stabilize this locking state of the locking piece, it is preferable that both notches are V-shaped.

The score line provided in the front plate is formed, for example, in a perforated shape. Therefore, as described above, in a state where the locking piece is locked in the cut hole, the front plate portion including the locking piece is broken along the cut line to separate it from the front plate. can do.

[0014] With such a locking structure of the locking piece and the notch hole, the mouth of the box body is closed, and the connecting plate is locked in contact with the inner surface of the front plate. In particular, the holding plate is fixedly arranged at a predetermined position in the paper box. As a result, the articles stored in the paper box body are stably held in a state of being strongly sandwiched between the presser plate and the bottom of the box body. This holding state is the same even when there are a plurality of stored articles.

Further, in the present invention, bottom plate pieces are continuously provided at the lower ends of the front plate and the rear plate via folding lines, and cutout portions are provided at end portions of these bottom plate pieces. One side edge is used as a locking edge, and a sticking tongue piece is continuously provided via a folding line on the other side edge side of the cutout portion facing the locking edge, and the front plate and the rear plate, the bottom plate piece and Are folded inward, and one protruding portion consisting of the bottom plate piece other than the notch is connected to the other bottom plate piece in a state where the locking edges are mutually locked. is engage the notch portion, by stick and fix the further bonded Chakushitahen a predetermined position of the outer surface of the other of the bottom plate pieces, Ru is formed as the bottom of the box body. This

Since these bottom plate pieces are bent inward at the corresponding fold lines, the engagement portions of these bottom plate pieces project into the box body. This protruding state of the engaging portion is obtained in a stronger state when the engaging portion of each bottom plate portion is formed in close contact. That is, the elastic force based on the paper material of the box main body acts on this engaging portion. As a result, the projecting state of the engagement portion of each bottom plate piece acts to push up the stored article into the box body. As a result, the articles stored in the box body are stably held in the box body by the pressing action from above and the pushing action from below by the holding plate. The holding state for such stored articles is the same even when there are a plurality of stored articles.

Further, since the attached one tongue piece is attached and fixed to a predetermined position on the outer surface of the other bottom plate piece, the projecting state of the engaging portion is stabilized, and
It is configured as a bottom portion of a box main body having sufficient strength to support stored articles. In this case, the sticking tongue piece is bent outward at the corresponding folding line, so that the above-mentioned protruding state of the bottom plate pieces at the engaging portions is ensured. Further, such a bottom portion configuration of the box body is different from the configuration in which one of the pasting tongue pieces is stuck and fixed at a predetermined position on the outer surface of the other bottom plate piece, and the bottom portion of the left and right side plates of the box body respectively. Provide a tongue,
The same configuration can be obtained by attaching the above-mentioned sticking tongue piece to a predetermined position on the outer surface of the tongue piece.
