  The shape of the brush tip of the makeup brush to which makeup powder is applied varies, and considering the touch, the brush tip attached to the tip of the brush shaft is larger than the tip of the brush shaft so that the area touching the skin increases. Many are thicker than the diameter.

As a packaging container for cosmetic brushes having large brush heads, the ones shown in FIGS. 30 and 31 are conceivable.
FIG. 30 is a developed view, and FIG. 31A shows a state where the brush ears 2b of the cosmetic brush 2 are packaged by the assembled packaging container 1. FIG.

  The packaging container 1 is configured by folding a polypropylene sheet. One side of the substantially triangular first side plate S1 and second side plate S2 is connected by a first folding line L1. A first flap F1 that is bent inward is connected to the tip of the first side plate S1 by a second fold line L2. A second flap F2 that is bent inward is connected to the tip of the second side plate S2 by a third fold line L3.

  On the opposite side of the second side plate S2 connected to the first side plate S1 at the first folding line L1, a flap F4 that covers the outside of the first side plate S1 bent at the first folding line L1 is connected at the folding line L7. ing. Further, a female surface fastener piece P1 is bonded to the inside of the flap F4. A male surface fastener piece P2 is bonded to a position outside the first side plate S1 corresponding to the surface fastener piece P1.

  Note that the second folding line L2 connecting the first side plate S1 and the first flap F1 is curved so that the center enters the inside of the first side plate S1 as compared to both ends of the first side plate S1. Similarly, the third folding line L3 connecting the second side plate S2 and the second flap F2 is curved so that the center enters the inside of the second side plate S2 as compared to the both ends of the second side plate S2.

  Thus, the 1st flap F1-the 6th flap F6 have covered and closed the opening part of the front-end | tip of a cylindrical body by inserting alternately under the adjacent flap. When the cosmetic brush 2 is stored in the storage space K from this state, the cosmetic brush 2 holding the brush shaft 2a is closed while receiving the opening of the base end B with one palm as shown in FIG. When the first flap F1 to the sixth flap F6 are inserted and separated from the first flap F1 to the sixth flap F6 in the state, the first flap F1 to the sixth flap F6 loses the strength of the waist of the sheet material to the weight of the makeup brush 2, and the base end From the sixth folding line L6 to the eleventh folding line L11, the tip part is elastically deformed toward the storage space K, the opening is opened, and the cosmetic brush 2 enters the storage space K and is stored. The first flap F1 to the sixth flap F6 through which the makeup brush 2 has passed self-returns to the original position.

Here, the size of the opening of the base end B is processed so as to be slightly smaller than the maximum diameter of the intermediate portion of the brush shaft 2a of the makeup brush 2, and the makeup brush 2 entering the storage space K is Even if you remove the palm you received, it will not fall off. Since the portion where the sixth side plate S6 and the flap F7 are overlapped includes a portion that is not bonded by the double-sided adhesive tape 61, when the cosmetic brush 2 is taken out through the opening of the base end B, When the brush shaft 2a exposed from the opening at the end B is grasped and pulled, this portion expands so that the maximum diameter portion of the brush shaft 2a of the cosmetic brush 2 can pass through and be taken out.
− Example 2 −
In FIG. 26, the case where the first flap F1 to the sixth flap F6 are bent at 90 ° with respect to the first side plate S1 to the sixth side plate S6 has been described. However, as shown in FIG. It is also possible to configure so as to block.

  In the above description, the overlapped portion of the sixth side plate S6 and the flap F7 has a portion that is not bonded by the double-sided adhesive tape 61, but depending on what is stored in the storage space K, The entire overlapped portion of the sixth side plate S6 and the flap F7 is bonded by the double-sided adhesive tape 61, or at least the distal end and the proximal end of the overlapped portion of the sixth side plate S6 and the flap F7 are attached. A double-sided adhesive tape 61 can be used for bonding.

  In the above-described sixth embodiment, a part or all of the sixth side plate S6 and the flap F7 are bonded together by the double-sided adhesive tape 61, but without using the double-sided adhesive tape 61, one of the sixth side plate S6 and the flap F7. The parts can be heat welded or the hook and loop fastener pieces P1 and P2 found in other embodiments can be connected by engagement.

  In the above description, the first side plate S1 to the sixth side plate S6 and the first flap F1 to the sixth flap F6 are integrally formed on the sheet material, but the opening of the tip is closed at the tip of the cylindrical formed body. In this manner, the base ends of the first flap F1 to the sixth flap F6 can be attached.

  In each of the above embodiments, as an example of the resin sheet material, the case of a single polypropylene sheet has been described as an example, but in the case of other resin sheets, when at least a part of the resin sheet is laminated with another material But it can be done in the same way. As a specific material used for laminating, woven fabric, non-woven fabric, paper or the like can be used.
