Description

  The present invention relates to an SN container capable of stacking and nesting and having a card holder on one side.

  Conventionally, as this type of SN container, a plurality of longitudinally bulging portions are formed by bulging a plurality of positions on the side wall to the outside and a receiving groove is formed on the inside thereof. In this SN container, when stacking, the lower end surface of the vertically bulging portion comes into contact with the upper surface of the counterpart SN container, and when nesting, the vertically bulging portion is received in the receiving groove of the counterpart SN container. The Further, the vertically long bulging portion is disposed in the vicinity of the corner portion where the strength is relatively high in the container by intersecting the side walls (see, for example, Patent Document 1).

In addition, there is known a card holder provided on one side wall of a normal container having no stacking and nesting functions. The card holder, for example, is fixed to the lower edge of one side wall and extends upward, and has a cantilever structure that can hold the card between the side wall (see, for example, Patent Document 2).

  By the way, when a card holder is provided on one side wall of the conventional SN container described above, a situation may occur in which the card holder interferes with the counterpart SN container and is crushed during nesting. On the other hand, for example, by changing the inclination angle in the direction in which the first side wall 4 provided with the card holder 3 is laid like the SN container 1 shown in FIG. As shown in FIG. 13, a configuration in which the space between the upper and lower first side walls 4 and 4 in the nesting state is widened and the card holder 3 is accommodated therein can be considered.

  However, in the case of such a configuration, as shown in the change in FIG. 12A to FIG. 12B, the lower end portion of the first side wall 4 enters the inner side as the first side wall 4 enters the inner side. The longitudinally bulging portions 6 in the second side walls 5 on both sides need to be separated from the corner portions (see arrow Y in FIG. 12A), and the strength can be lowered.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an SN container capable of preventing card holder interference during nesting while ensuring strength.

  The SN container according to the invention of claim 1 made to achieve the above object can be provided with a card holder on the outer surface of at least one first main side wall of a pair of first main side walls opposed to each other. A part of the second main side walls bulge outwardly at a plurality of positions of the pair of second main side walls opposed to each other across the first main side wall to form a plurality of vertically long bulging portions. SN container with the inside of the receiving part as a receiving groove, and the lower end of the vertically bulging part is abutted against the upper surface of the counterpart SN container to be in a stacking state. The parts are received and become a nesting state, the predetermined portions of the upper and lower SN containers in the nesting state come into contact with each other, and the upper and lower first main side walls are separated from each other, and between the first main side walls In the SN container in which the card holder is accommodated, one end portion in the lateral direction of the first main side wall is bulged outward to form a vertically elongated bulged portion, and one side portion of the vertically elongated bulged portion is the expanded bulged portion. A vertically bulging portion is arranged at the lateral end of the second main side wall so as to rise from one side, and is inclined so that the lower end side of the first main side wall is directed inward, and the vertical line of the first main side wall The inclination angle with respect to is larger than the inclination angle with respect to the vertical line of the second main side wall.

  According to a second aspect of the present invention, in the SN container according to the first aspect, the expansion bulges are respectively arranged at positions facing each other between the pair of first main side walls, and both ends of the one second main side wall This is characterized in that the vertically bulging portion of the portion is arranged so as to rise from one side of each expansion bulging portion.

  The invention according to claim 3 is the SN container according to claim 1 or 2, wherein the portion extending from the expanded bulge portion provided at one end portion to the other end portion of the first main side wall is a flat surface, and the card holder is The lower end portion is fixed to the SN container and extends upward, and is characterized in that it has a cantilever structure in which a card can be sandwiched between the first main side wall.

  According to a fourth aspect of the present invention, in the SN container according to the third aspect, a flange portion projects laterally from the upper end portion of the SN container, and a portion of the lower surface of the flange portion on the opposite side of the expansion bulge portion across the card holder Is characterized in that a card locking portion that can be locked at the upper corner of the card is formed.

Is housed. Here, when the inclination angle of the first main side wall with respect to the vertical line is increased, the distance between the upper and lower first main side walls is increased, and a relatively thick card holder can be accommodated. At this time, in the conventional one, it is necessary to separate the vertically elongated portion from the corner portion in accordance with the change in the inclination angle of the first main side wall. However, in the present invention, one end portion in the lateral direction of the first main side wall is formed. By forming the expanded bulge portion by bulging outward, one second main side wall and the first main side wall are separated from each other with the expanded bulge portion interposed therebetween, and the effect of changing the inclination angle of the first main side wall Not receive. And the vertically long bulging part of one 2nd main side wall can be arrange | positioned in the edge part of the 2nd main side wall, approaching the front-end | tip corner part of an expansion | swelling bulging part, and intensity | strength is ensured. As described above, according to the present invention, it is possible to secure the strength by arranging the vertically bulged portion near the corner portion of the SN container, and it is possible to prevent the interference of the card holder during nesting.

  Specifically, as in the second aspect of the invention, the expansion bulges are respectively disposed at positions opposed to each other between the pair of first main side walls, and the vertically long ends of one end of the second main side wall. It is preferable to arrange the bulging portion so as to rise from one side of each expansion bulging portion.

  According to the configuration of the third aspect, since the portion extending from the expanded bulge portion provided at one end portion to the other end portion of the first main side wall is made flat, the card is inserted into the card holder along the flat surface. It can be easily inserted inside. Then, the card inserted inside the card holder can be abutted against the expansion bulge and positioned. According to the fourth aspect of the present invention, the upper end corner of the card inserted into the card holder can be locked to the card locking portion to prevent the card from being removed, and the card is protected from above by the flange portion.
