Description

Packing for cosmetic container and cosmetic container

The present invention relates to packing for cosmetic containers and cosmetic containers.

It is important for a cosmetic container for applying a cosmetic that a user can operate the container comfortably and apply a cosmetic such as mascara.

For example, Patent Document 1 proposes a device which can be used more easily as compared with the prior art device.

Patent No. 4520201 gazette

17 and 18 are views showing an example of a conventional cosmetic container. As shown in the schematic cross-sectional view of FIG. 17, the container main body 100 is configured of a body portion 102 and a connection portion 104. Cosmetics are stored in the torso unit 102. A packing 110 is fixed to the inside of the connection portion 104. The packing 110 is adapted to be able to put the applicator 120 in and out. The applicator 120 comprises a shaft portion 122 and a brush 124 fixed to the tip thereof. The brush 124 is formed of a sponge-like material with hair.

The packing 110 has an inner circumferential surface 110 a and an upper surface 110 b. The inner circumferential surface 110a extends downward substantially perpendicularly from the upper surface 110b. The upper surface 110b is flat.

By the way, in order for the user to comfortably use the cosmetic container for application, it is necessary to avoid a situation in which the user's hand becomes soiled or a situation in which the cosmetic container itself is soiled by the cosmetic stored in the cosmetic container. is there. In the conventional cosmetic container shown in FIGS. 17 and 18, the brush 124 is not inserted unless the applicator 120 is inserted in a direction in which the central axis of the packing 110 in the longitudinal direction extends (hereinafter referred to as "central axis direction"). There is a problem that the cosmetic comes in contact with the upper surface 110b and the cosmetic adheres to the upper surface 110b. That is, as shown in FIG. 17, the brush 124 is in contact with the upper surface 110b with only a slight deviation of the direction in which the applicator 120 is inserted from the central axis direction.

In addition, in order to carry out the makeup in accordance with the user of the cosmetic container, the amount of the cosmetic adhering to the brush 124 and the position on the brush 124 to which the cosmetic adheres (for example, the tip or center of the brush 124) is important. Therefore, the user squeezes the brush 124 in the vicinity of the opening of the packing 110 to adjust the amount of the cosmetic adhering to the brush 124 and the position on the brush 124 to which the cosmetic adheres (hereinafter referred to as “ "Fine adjustment".) There is a case. Specifically, as shown in FIG. 18A, the vicinity of the opening on the opposite side of the user's eye E1, more specifically, the corner portion where the inner peripheral surface 110a and the upper surface 110b are connected (hereinafter referred to as “corner portion The above-mentioned fine adjustment is performed by bringing the brush 124 into contact with the above and moving the brush 124 outward as shown by the arrow U1. When the brush 124 is closed at the corner, as shown in FIG. 18B, the part 200a of the cosmetic adhering to the brush 124 moves to the inner circumferential surface 110a, but the inner circumferential surface 110a is almost Since the cosmetic 200a extends vertically downward, the cosmetic 200a falls rapidly downward as indicated by the arrow D1. Since the inner circumferential surface 110a extends downward substantially perpendicularly from the upper surface 110b, the user's eye E1 must look into the inner circumferential surface 110a, and the outer circumferential surface 110a is outside. Cosmetics can not be clearly viewed because it is difficult for light from them to enter. For this reason, it is difficult for the user to confirm how much the cosmetic 200a has been rubbed off. In other words, it is difficult for the user to grasp how much the cosmetic remains on the brush 124. In the case where the user has made more erosion than intended, it is necessary to reinsert the brush 124 into the container body 100 and make adjustments from the beginning. Furthermore, since the upper surface 110b is flat, if the brush 124 is squeezed at the corner portion, the cosmetic may remain on the upper surface 110b of the cosmetic part 200b and the cosmetic container itself may be soiled, which may in turn result in contamination of hands and the like. There is.

In the light of the above, the present invention provides a packing and a cosmetic container for a cosmetic container which enables the user to more comfortably use the cosmetic container.

A first invention is a packing for a cosmetic container, in which an applicator for applying a cosmetic is inserted and withdrawn, and disposed at an opening of a cosmetic container body in which the cosmetic is stored, The open end opposite to the cosmetic container body is formed in a projecting shape in the direction opposite to the cosmetic container body, and a portion between the main body of the packing and the open end is A first inclined portion gradually expanding in diameter from the main body toward the opening end, a terminal end of the first inclined portion being the opening end, and a diameter of the opening end being: It is packing for cosmetics containers comprised larger than the diameter of the outer peripheral surface of the wall part which comprises the said main-body part.

According to the configuration of the first aspect of the present invention, the diameter of the end (opening end) of the first inclined portion of the packing is larger than the diameter of the outer peripheral surface of the wall constituting the main body, Therefore, even when the user inserts the applicator into the cosmetic container main body from the direction relatively largely deviated from the central axis direction, the applicator is not limited as long as it is in the range of the inside of the terminal end. One slope can be slid into the cosmetic container body. Further, since the projection is formed in a direction opposite to the main body, that is, upward, the cosmetic does not remain at the end even if the applicator comes in contact with the end, or Even if it remains, the remaining amount is extremely small as compared with the conventional example in which the open end is flat. Since the first inclined portion has a predetermined angle with respect to the central axis direction, the user scrapes the applicator at the first inclined portion or the end portion, and a part of the cosmetic adhered to the applicator Is moved to the first inclined portion, the cosmetic remains on the first inclined portion for a relatively long time. And since the first inclined portion is greatly expanded in diameter, the user is likely to have an angle smaller than 90 degrees between the surface of the first inclined portion and the user's line of sight in relation to the angle of the user's line of sight Since the first inclined portion on the side opposite to the eye is easily visible and external light is easily incident, the visibility is improved. Therefore, the user can comfortably carry out the fine adjustment of the cosmetic amount attached to the applicator at the first inclined portion. Thus, the user can use the cosmetic container more comfortably.

According to a second aspect of the present invention, in the configuration of the first aspect, the second open end of the packing on the cosmetic container body side is configured as a first cosmetic adjustment mechanism which is smaller than the outer shape of the applicator. The packing for a cosmetic container, wherein the first inclined portion is configured as a second cosmetic adjustment mechanism formed so that the direction of the perpendicular to the tangent line approaches the vertical direction toward the end portion. It is.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, the cosmetic container 1 (hereinafter, referred to as "container 1") includes a cap portion 10 and a cosmetic container main body 50 (hereinafter, referred to as "container main body 50"). The container main body 50 is an example of a cosmetic container main body. The container body 50 stores cosmetics such as mascara and liquid foundation. In the container 1, the direction in which the cap 10 is located is referred to as the upper side (upper side), and the direction in which the container body 50 is located is referred to as the lower side (lower side). The higher the position, the higher the position, and the lower, the lower the position. Further, the direction of a virtual central axis Z1 in the longitudinal direction of the container 1 (hereinafter, referred to as "central axis Z1") is referred to as the inside, and the direction away from the central axis Z1 is referred to as the outer. The direction in which the central axis Z1 extends is also referred to as the vertical direction.

The container 1 is configured in a substantially cylindrical shape in which the diameter in the vicinity of both ends is larger than the diameter of the central portion. And, the maximum diameter near one end is larger than the maximum diameter near the other end. The maximum diameter of the cap 10 is smaller than the maximum diameter of the container body 50. The container 1 is large enough to be held by the user with one hand, and for example, the entire length L1 of the container 1 is 130 mm (millimeters), and the maximum diameter W1 is 20 mm.

As shown in FIG. 3, the container body 50 includes a body 52 and a connection 54. A male screw 54 a is formed in the connection portion 54.

The shaft 40 is fixed to the cap 10. A brush 42 is fixed to the tip of the shaft 40. The brush 42 is an example of an applicator for applying a cosmetic. The brush 42 is formed of a sponge-like material having a haired foot. Both ends of the connection portion 54 are open so that the shaft portion 40 and the brush 42 can be stored in the body portion 52. That is, the brush 42 is inserted into and withdrawn from the container body 50.

The lower end of the cap portion 10 is open, and a substantially cylindrical concave space 10S is formed. A female screw (not shown) is formed on the inner side wall portion 10a constituting the concave space 10S, and the cap portion 10 is detachably attached to the container main body 50 by engaging with the male screw 54a of the container main body 50. It is supposed to be fixed.

As shown in FIG. 4, a packing 20 is fixed to the inside of the connection portion 54 of the container main body 50. In FIG. 4, the description of the male screw 54 a of the connection portion 54 is omitted. The same applies to FIGS. 7 to 13. The packing 20 is an example of packing for a cosmetic container. Further, the upper end portion 40a (see FIG. 7) of the shaft portion 40 is fixed to the space 10S2 (see FIG. 7) near the upper end of the cap portion 10. The brush 42 passes through the packing 20 and is inserted into and withdrawn from the container body 50.

The container body 50 is formed, for example, by injection molding of polypropylene (PP). The cap portion 10 is formed, for example, by injection molding of polyethylene terephthalate (PET). The packing 2 is formed, for example, by injection molding of polyethylene (PE).

As shown in FIGS. 5 and 6, the packing 20 is formed in a cylindrical shape as a whole, and is configured of a packing main body 20 a and an enlarged diameter portion 20 b. The packing main body 20a is an example of a packing main body. Annular convex parts 20 a 1 and 20 a 2 are formed on the outer peripheral surface 20 aa of the packing main body part 20 a, and it is easy to fix the inside of the connection part 54.

The enlarged diameter portion 20b includes an upper end portion (opening end portion) 20ba, a first inclined portion 20bb, a second inclined portion 20bc, a vertical portion 20bd, and a lower end portion 20be. The upper end 20ba is an example of an open end. The first inclined portion 20bb is an example of a first inclined portion. The second inclined portion 20bc is an example of a second inclined portion.

The packing 20 is formed in a cylindrical shape in which the diameter of the upper end portion 20ba is larger than the diameter of the outer peripheral surface of the packing main portion 20a. The first inclined portion 20bb is configured to gradually expand in diameter from the inner side surface 20ab of the packing main portion 20a toward the upper end portion 20ba. The end of the first inclined portion 20bb is the upper end 20ba. The first inclined portion 20bb is configured as a curved surface portion convex toward the vertical axis Z2 direction of the packing 20. That is, the first inclined portion 20bb is configured such that the direction of the perpendicular to the tangent line approaches the vertical direction toward the upper end portion 20ba.

Further, the upper end portion 20ba is formed to project upward. Specifically, the upper end portion 20ba is formed as a curved surface. The upper end portion 20ba is located outside the outer surface (outer peripheral surface 20aa) of the wall portion that constitutes the packing main portion 20a (see FIG. 6). That is, the diameter dC of the upper end portion 20ba is larger than the maximum diameter dB of the outer peripheral surface 20aa of the packing main portion 20a. Further, the upper end portion 20ba is configured as the uppermost portion which is the highest position in the packing main portion 20a. The upper end 20ba is also an example of the end.

The second inclined portion 20bc is an outer portion outside the upper end portion 20ba, is inclined to be lower toward the outer side, and is configured lower than the upper end portion 20ba. In other words, the second inclined portion 20bc is inclined downward from the upper end portion 20ba. The outermost part of the packing 20 has the largest diameter dD. The diameter dF of the lower opening 20 ac of the packing 20 is slightly smaller than the diameter of the brush 42. Thereby, when drawing out the brush 42 to which the cosmetic has adhered from the packing 20, the excess cosmetic is dropped at the lower opening 20 ac of the packing 20. That is, the lower opening 20 ac is an example of a first cosmetic adjustment mechanism that adjusts the amount of cosmetic adhering to the brush 42.

The inclination angle (inclination angle with respect to the vertical axis Z2) θ2 of the central portion of the second inclined portion 20bc is substantially equal to the inclination angle θ1 of the first inclined portion 20bb, or the inclination angle θ2 is defined to be the inclination angle θ1 or less. In FIG. 6B, the direction in which the vertical axis Z2 extends is the vertical direction. In the present embodiment, the inclination angle θ2 is 20 degrees, and the inclination angle θ1 is 35 degrees.

The ratio (dC / dA) of the opening diameter dC of the end (i.e., the upper end 20ba) of the first inclined portion 20bb to the average opening diameter dA of the packing main portion 20a is defined as 1.5 or more and 1.6 or less. In the present embodiment, dA is 5.6 mm, dC is 8.4 mm, and the ratio (dC / dA) is 1.50.

As shown in FIGS. 7 and 8, the packing 20 is pushed into the connection portion 54, and the outer peripheral surface 20aa of the packing 20 is in contact with the inner peripheral surface 54b of the connection portion 54 and fixed. The packing 20 is fixed to the connection portion 54 in a state in which the lower end portion 20be of the enlarged diameter portion 20b of the packing 20 is in contact with the upper end portion 54c which is the upper end of the connection portion 54.

Hereinafter, with reference to FIGS. 9-13, the state which the brush 42 fixed to the axial part 40 passes the packing 20, and is inserted in the container main body 50 is demonstrated. Although the brush 42 may be inserted into the container main body 50 from the direction of the extension of the central axis Z1 of the container main body 50 (central axial direction) as shown in FIG. 9, as shown in FIG. It may be inserted into the container body 50 from a direction deviated from the central axis direction.

As long as the brush 42 is inserted from a position inside the upper end 20ba of the packing 20 (see FIG. 10), the brush 42 contacts the first inclined portion 20bb (see FIG. 11) and further along the first inclined portion 20bb Sliding (see FIG. 12) is finally inserted into the container body 50 from the central axial direction (see FIG. 13). That is, as the brush 42 is smoothly guided from the upper end portion 20ba to the first inclined portion 20bb, the brush 42 is inserted into the container main body 50 without being caught.

Next, with reference to FIG.14 and FIG.15, the method to implement the fine adjustment of the quantity of the cosmetics adhering to the brush 42 is demonstrated. As shown to Fig.14 (a), a user performs fine adjustment using 1st inclination part 20bb. The first inclined portion 20bb is an example of a second cosmetic adjustment mechanism. The user finely adjusts the amount of cosmetic by bringing the brush 42 into contact with the portion of the first inclined portion 20bb opposite to the eye E1 and moving the brush 42 outward as shown by the arrow U1. I do. That is, the user passes the brush 42, which has excess cosmetic once dropped at the lower opening 20ac (see FIG. 6A), through the inner side surface 20ab, and pushes the brush 42 to the first inclined portion 20bb. Then, it is slid toward the upper end portion 20ba, squeezed at the upper end portion 20ba, unnecessary adjustments are made, or fine adjustments such as adjusting the position on the brush 42 to which the cosmetics are attached are performed. The user visually recognizes the amount of the cosmetic moved from the brush 42 to the first inclined portion 20bb, and if the amount of the moved cosmetic is insufficient, presses the brush 42 again to the first inclined portion 20bb. Fine adjustment of the amount of cosmetics, etc. Since the upper end 20ba is not flat, the cosmetic does not remain on the upper end 20ba.

Since the first inclined portion 20bb has a predetermined angle with respect to the vertical axis Z2 direction (see FIG. 6B), the user can use the brush 42 as shown in FIG. As shown in), when the portion 70 of the cosmetic attached to the brush 42 is moved to the first inclined portion 20bb, the cosmetic 70 remains on the first inclined portion 20bb for a relatively long time. For this reason, the user uses the first inclined portion 20bb like a pallet used when drawing a picture, and finely adjusts the amount of cosmetic adhering to the brush 42 and the position where the cosmetic adheres to the brush 42. It can be adjusted.

The inclination of the first inclined portion 20bb is adjusted to an angle at which the cosmetic moved from the brush 42 can be easily viewed. Specifically, as shown in FIG. 15A, a tangent at the central portion 20bb1 of the first inclined portion 20bb is L11, and a line perpendicular to the tangent L11 is a perpendicular L21. Then, a tangent in the upper portion 20bb2 above the central portion 20bb1 of the first inclined portion 20bb is L12, and a line perpendicular to the tangent L12 is a perpendicular L22. The tangents L11 and L12 are displayed slightly away from the first inclined portion 20bb for convenience. Assuming that the angle between the perpendicular L21 and the horizontal line L3 is an angle θ11, and the angle between the perpendicular 22 and the line L3 is an angle θ12, the angle θ12 is larger than the angle θ11. That is, the perpendicular L22 is closer to the perpendicular than the perpendicular L21. Therefore, as shown in FIG. 15B, when the eye E1 of the user visually recognizes the central portion 20bb1 of the first inclined portion 20bb in the direction of the perpendicular L21, the portion above the central portion 20bb1 is The external light is taken into the first inclined portion 20bb from the direction of the perpendicular L22 closer to the perpendicular than the perpendicular L21 or the direction of the perpendicular L23. Since the first inclined portion 20bb is expanded in diameter so as to have a diameter larger than that of the packing main portion 20a, the first inclined portion 20bb is opposite to the eye E1 of the user in relation to the angle of the line of sight of the eye E1 of the user. It is easy to visually recognize the cosmetics 70 (refer FIG.14 (b)) adhering to the 1 inclination part 20bb. That is, as shown in FIG. 15 (b), the cosmetic 200a attached to a wall close to the line of sight of the user's eye E1 as in the prior art shown in FIG. 18 (b) is used. The visibility is better when looking at the cosmetic 70 (see FIG. 14B) attached to the first inclined portion 20bb inclined in the direction of the line of sight of the person's eye E1. In addition, since the diameter of the first inclined portion 20bb is enlarged so as to be larger than the diameter of the packing main portion 20a, it is difficult to make a shadow and the external light easily enters, thereby improving the visibility.

Therefore, the user can comfortably carry out the fine adjustment of the cosmetic amount attached to the brush 42 in the first inclined portion 20bb.

Second Embodiment
The second embodiment will be described with reference to FIG. Descriptions in common with the first embodiment will be omitted.

In the packing main body 20A of the second embodiment, the ratio (dC / dA) of the opening diameter dC of the end of the first inclined portion 20bb (that is, the upper end 20ba) to the average opening diameter dA of the packing main body 20a is It is smaller than the case of the packing main body 20 of one embodiment. Further, the inclination angle θ2 is equal to the inclination angle θ1.

The cosmetic container of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
