Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic storage container, and more particularly to a blister container.

[0002]

2. Description of the Related Art At present, cosmetics are produced in a wide variety of applications, and correspondingly, there are containers for storing a variety of applications.

As one of the forms of this container, there is a blister container in which a flat plate such as a resin plate is manufactured into a three-dimensional shape by a vacuum molding method.

Since this blister container is light in weight, can be easily molded into a complicated shape, and is inexpensive to manufacture, it is not only used as a filler inside the container used in conventional cosmetic containers, but also the blister container itself. Is sold by filling cosmetics inside as an exterior material, which contributes to cost reduction of cosmetics.

Further, as a feature of this blister container, by using a transparent and thin resin, the cosmetic product inside the container can be visually recognized without opening the lid, and from the viewpoint of the consumer, the cosmetic product actually used It is very conscientious because you can purchase after checking the color etc.

However, since the blister container is originally formed as a flat thin plate into a three-dimensional shape by the vacuum molding method, the place where the hinge between the lid and the container is installed is limited and the place where the cosmetic is inserted is limited. Limited to one side only, etc.
3 methods such as casting method that casts liquid resin into the mold and molding, and shaving method that cuts the container from the resin mass.
Its shape and method of use were specified as compared with a container formed by three-dimensional molding.

Therefore, in the cosmetics using the blister container, the area of the container is increased so that several recesses can be provided on one side,
If you want to put the cosmetics in the horizontal parallel type that molds the recesses into which the cosmetics such as puffs and riffers are inserted, and mold them, and use the puffs together,
We have taken countermeasures such as putting it on a blister container and putting it in an individual box.

[0008]

However, in the above countermeasures, the blister container becomes larger than the cosmetics contained therein, and it becomes a double packaging by putting it in another individual box, which impairs the advantages of the blister container. There were problems such as.

Further, in the configuration of the horizontal blister type blister container described above, since one lid is also used as a lid for a large number of accommodating places, the result is that other cosmetic lids that are not necessary at the time of opening the lid are opened. There was also a possibility of accidentally dropping other cosmetics.

Therefore, the present invention has been made in view of the above-mentioned problems, and a cosmetic container made of a blister container can be formed without requiring an extra size, and a lid for covering each accommodating space for cosmetics can be opened and closed. The purpose is to be.

[0011]

The present invention adopts the following means in order to solve the above problems.

Therefore, each accommodation part has its own lid, and each accommodation part can be opened and closed individually.

Further, by folding and stacking the accommodating parts, if the vertical projecting areas of the accommodating parts are equal, the vertical projecting area of the multi-stage simple accommodating container constituted by accumulating the accommodating parts is also the accommodating part. The vertical projection area is equal to the vertical projection area, and the area required for display is smaller than the amount of cosmetics contained.

In constructing an individual accommodation portion in each accommodation portion, the accommodation portion has an upper wall provided with a recess and a side wall extending downward from the periphery of the upper wall, and the inside and outside of the side wall. When a stair-like step is provided on one of the accommodating parts and the other accommodating part is superposed on the other accommodating part, the upper wall of the other accommodating part enters into the inside surrounded by the side wall of the one accommodating part and is located at the step position. Are locked and one accommodation part is fitted into the other accommodation part. Therefore, a space is established from the step position formed on the inner and outer surfaces of the side wall of one accommodation part to the upper wall of the one accommodation part at the time of stacking, and the formed space can be used as an accommodation place by providing a concave portion.

In order to keep the storage portion of the storage portion closed by another storage portion overlapping the upper wall and the lid, the first storage portion and the second storage portion whose vertical isometric projection is square. In the case of overlapping, the first concave-convex engaging portion is provided on a part of the inner surface of the side wall of the first accommodating portion, while the concave-convex part is formed on a part of the outer surface of the side wall of the second accommodating portion overlapping with the accommodating part. A second concave-convex engaging portion that engages with the groove-like engaging portion is provided. When the respective accommodating parts are overlapped and the second accommodating part upper wall and the side wall enter the first accommodating part side wall, the first concavo-convex engaging part and the second concavo-convex engaging part engage with each other. It is held in a closed state between the accommodating portions that are overlapped with each other.

Similar to holding the first and second housings closed as described above, a portion of the overlapping surface of the lid is used to hold the housing closed with a lid. While providing the first concave-convex engaging portion, the second concave-convex engaging portion is provided on a part of the overlapping surface of the accommodating portion which overlaps with the lid. When the lid and the accommodating portion are overlapped with each other, the first concave-convex engaging portion and the second concave-convex engaging portion engage with each other to hold the accommodating portion and the lid closed.

In addition to the above-mentioned holding between the accommodating portions or the accommodating portions or between the accommodating portions and the lid, the first segment is continuously provided around the lid with the lid, and at the bottom of the accommodating portion. When the second piece is oriented downwards and the second piece is oriented upwards, the second section is continuously formed around the periphery, and when the second section is directed upwards, it is polymerized between the lid and the lowermost accommodation section. Engagement portions that engage with each other are provided on the side portions of the accommodating portions that are stacked together. Therefore, by engaging the uppermost lid and the section of the lowermost accommodation part, the accommodation parts are bundled and held in a closed state, and the impact between the accommodation parts due to an accidental drop of the container, etc. And prevent the lid from opening.

As for the material of the container, at least the recess and the lid forming the storage space are transparent, and the color and shape of the objects in the top lid and the bottom storage portion may be visible. .

With respect to the direction in which the accommodating parts are opened, when the accommodating parts and the lid are formed so that the vertical isometric projections when superposed have a square shape, the accommodating parts are stacked in a series and the open position is In addition to the case of forming a pair of sides, the connecting portions that connect the respective housing portions and the lids are sequentially arranged on the first side and the second side that are adjacent to each other in the above-mentioned rectangle so that they are adjacent to each other.

In addition, in the case where the cosmetics contained in the accommodating portion have a property of disabling light, there are cases where the inside of the accommodating portion cannot be seen from the outside by using a light-shielding material.

[0050]

By carrying out the present invention, it is possible to manufacture a container capable of storing a large number of cosmetics in the same area as a container for storing one cosmetic. Although a single container has a large number of cosmetic storage locations, each storage location has its own unique lid and can therefore be opened individually. Each container does not open carelessly because it has a place to bundle and hold the containing parts having each containing part, and the opening position of each containing part can be changed by changing the connecting position of the connecting part which is a hinge. It is also possible to set it to a position where it can be easily opened across the storage section. When this container is vacuum-molded from a transparent plastic sheet, the inside can be viewed without opening the lid. Further, it is possible not only to store another container filled with the cosmetic product in the storage unit, but also to directly store the cosmetic product itself in the storage unit.
