Description

  The present invention relates to a molding tray for fixing a product in an outer box and can be used in common for products having different overall lengths.

  When the product is stored in the outer box, a plastic molding tray is used to suppress the movement, displacement, and rattling of the product in the outer box and to protect the product from impact.

  Conventionally, the molding tray is manufactured for each product according to the shape and size of the product and the outer box. For example, when one type of outer box is commonly used as the outer box of two types of bar-shaped products having different overall lengths, two types of molding trays are required. However, since the molding tray is only discarded after the product is taken out from the outer box, it is not preferable from the economical and environmental viewpoints to produce two types of molding trays in such a case.

In order to solve this problem, a plastic container for storing a product, in which a plastic fixing flap is provided in a plastic case, has been proposed as a means for reducing the amount of plastic for fixing the product in the container. (Patent Document 1).
In addition, it has been proposed to mount a tray for sandwiching and fixing a part of a product in a general-purpose general storage case (Patent Document 2).

  However, since the plastic case having the product fixing flap of Patent Document 1 does not have a shock-absorbing effect against impact, the product cannot be sufficiently protected against impact such as dropping. In line work, it is difficult to set the product in this plastic case.

  The tray that sandwiches a part of the product of Patent Document 2 also has a concern that the buffering effect of the tray is difficult to reach the product in a portion that is not sandwiched, and the product is damaged by a drop impact.

  In response to such problems of the prior art, the present invention is a molded tray for fixing a product in an outer box, which can be used in common for products having different overall lengths and has an excellent buffering effect against impact. The purpose is to provide.

  In order to achieve the above-mentioned object, the present invention is a molded tray for fixing a product in an outer box, and a flap is provided on at least one end in the longitudinal direction of the tray via a hinge, and the flap is an upper surface thereof. A side bank is provided on both side edges in the longitudinal direction of the tray in a range that does not reach the entire length of the both side edges, and the side in the absence of the side bank in the longitudinal direction of the tray. A tray with a pillow-like bank that is lower than the bank is provided.

  According to the tray of the present invention, the long product is placed between the side banks so as to be placed on the pillow bank, and the short product is fitted between the side banks so that the end of the short product hits the pillow bank. Therefore, when the two types of products having different lengths are accommodated in the outer box, not only the outer box but also the tray can be used in common.

  In addition, the tray of the present invention has a buffering effect against the impact in the longitudinal direction and the impact in the short direction for both the long product and the short product. Is possible.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

The tray 1 is a stick-shaped or column-shaped cosmetic product such as an eyebrow pencil, an eyeliner pencil, a lip pencil, etc., and is a molding tray for two types of products having different lengths. By molding a single plastic sheet Is formed.

  The tray 1 has a flap 3 via a hinge 2 at one end in the longitudinal direction, and the flap 3 has a buffer portion 4 that is convex on the upper surface side. As will be described later, the flap 3 is bent as indicated by an arrow toward the upper surface side, that is, the side having the buffer portion 4 by the hinge 2, and takes a position indicated by a broken line. It becomes a cushioning material at the end of the inserted long product.

  An end bank 5 is provided at the other end of the tray 1 in the longitudinal direction. The end bank 5 has a form in which the sheet material is folded in two, and the fold mountain is the end bank upper surface 5a. A stepped portion 6 is formed at the lower end of the end bank 5 so as to protrude toward the center of the tray. The upper surface 6a of the stepped portion 6 preferably matches the outer shape of the long product to be fitted into the tray 1. For example, when placing a round bar-shaped product, it may be a concave curved surface as shown in the figure. preferable.

  It is preferable to adjust the height L5 of the end bank 5 and the length of the flap 3 (that is, the height when the flap 3 is bent as shown by an arrow) L3 in accordance with the shape of the outer box. For example, when the outer box is a normal rectangular parallelepiped, the height L5 of the end bank 5 is preferably the same as the length L3 of the flap 3.

  On the other hand, side banks 7 are provided on both side edges in the longitudinal direction of the tray 1 within a range that does not reach the full length of both side edges. The side bank 7 also has a form in which the sheet material is folded in two and the fold mountain is the side bank upper surface 7a. A space sandwiched between the side banks 7 on both side edges of the tray 1 is a product fixing recess 8. The side bank 7 may be formed independently of the end bank 5, but as shown in the figure, it is preferable that the side bank 7 is continuous in terms of improving the shock absorbing function against impact.

  It is preferable that the height L5 of the end bank 5 and the height L7 of the side bank 7 are the same, or the end bank 5 is higher than the side bank 7. Thereby, the plastic amount of the tray 1 can be reduced without reducing the shock absorbing capacity.

  Further, the thickness Lw5 of the end bank 5 other than the stepped portion 6 is preferably substantially the same as the height L4 of the buffer portion 4 of the flap 3. As a result, the shock-absorbing capacity is substantially the same on the flap 3 side and the end bank 5 side.

  A pillow bank 10 is provided near the flap 3 in the side bank non-existing region 9 in the longitudinal direction of the tray 1. The upper surface 10a of the pillow-shaped bank 10 is preferably matched with the outer shape of the long product to be fitted into the tray 1 in the same manner as the stepped portion 6 described above. As described above, a concave curved surface is preferable.
