Description

[Detailed Description of the Invention] This invention relates to a cosmetic container mainly used to store liquid cosmetics such as lotion, hair conditioner, hair nourishing agent, shampoo, and the like.

Several containers for cosmetics, etc. of this type have been provided in the past, but all of them have problems with the means for locking the lid to the neck of the container body, and the lid tends to return easily, causing liquid cosmetics, etc. to leak out. Not only is this a risk, but the repelling effect and repelling effect of the locking means of the lid, as well as the appearance, etc., are unfavorable. In addition, the body of the container is slippery, making it difficult to handle during use.
Moreover, it had drawbacks such as weak strength of the container body and lid.

This invention aims to eliminate the various drawbacks of the conventional technology as described above, and its gist is that it consists of a container body and a lid. And on the rear surface, there is a non-slip part that also serves as a decoration and has protrusions arranged in parallel in the vertical direction in a substantially wavy shape. The lid is formed to have a locking protrusion having an inclined part and a vertical part at positions facing each other with the mouth part as the boundary, while the lid is provided at the center of the lower plate of the exterior plate having a curved part at the upper front side. is provided with a recess for fitting the neck portion, and a stop piece provided near the recess on the lower surface of the lower plate for abutting the stop protrusion and a position opposite thereto with the recess as a boundary are provided with a recess in the longitudinal direction. A locking piece having an arc-shaped cross section and a groove-shaped cross-section in the transverse direction is elastically protruded so that the tip side is open and faces in the same direction in the circumferential direction, and the base of this locking piece is A relief hole is provided in the lower plate opposite to the part other than the end side to prevent the locking piece from coming into contact with it, and a middle reinforcing piece and a front reinforcing piece assembled in a substantially I-shape are provided on the upper surface of the lower plate around the recess. , a rear reinforcing piece, and a pair of hook-shaped rear corner reinforcing pieces are formed.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, A is a container body made of plastic that stores liquid cosmetics, etc., and this container body A has approximately triangular side surfaces on the front and rear surfaces of the outer circumferential surface of the body 1 having a bottomed rectangular cylindrical shape. A decorative non-slip part 3 is provided in which protruding pieces 2 are arranged vertically in parallel in a substantially wavy shape, and an inner stopper 5 is provided in the center of the upper plate 4 at the upper end of the body part 1.
A male thread 7 is provided on the outer peripheral surface of the neck portion 6, and a stop protrusion 8 is provided near the neck portion 6 on the upper surface of the upper plate 4. At a position facing this stop protrusion 8 with the mouth part 6 as a boundary, there is a sloped part 9 that gradually becomes higher as it goes from one end side to the other end side, and this sloped part 9.
A locking protrusion 11 having a vertical portion 10 that is suddenly lowered from the top thereof is formed so that the vertical portions 10 are oriented in the same direction in the circumferential direction.

On the other hand, B is a plastic lid that closes the neck part 6 of the container body A, and this lid B is attached to the lower part of a substantially cylindrical exterior plate 13 having a curved part 12 at the upper front side. A lower plate 15 is provided which is slightly recessed from the peripheral edge, and a recess 17 having a female thread 16 on the inner peripheral surface is provided in the center of the lower plate 15.
A stop piece 18 is provided near the recess 17 on the lower surface of the lower plate 15 (the upper surface in FIG. , a locking piece 19 having an arcuate cross section in the longitudinal direction and a groove shape in the transverse direction;
are elastically protruded so that the distal ends thereof are open and facing the same direction in the circumferential direction, and a locking piece is provided on the lower plate 15 facing the portion of each locking piece 19 except for the proximal end side. A hole 20 for preventing the locking piece 19 from coming into contact with the locking piece 19 is formed so as to be at least larger than the plane size of the locking piece 19 . In addition, as shown in FIG. 3, on the upper surface of the lower plate 15 around the recess 17 of the lid B, there are a middle reinforcing piece 21, a front reinforcing piece 22, a rear reinforcing piece 23, and a pair of hook-shaped reinforcing pieces arranged in a square shape. A rear corner reinforcing piece 24 and the like are provided.

Then, the lid B is attached to the neck part 6 of the container body A.
At the final stage, the stop piece 18 of the lid B comes into contact with the stop protrusion 8 of the container body A, and at the same time each locking of the lid B is screwed into the recess 17 of the The pieces 19 ride over the locking protrusions 11 of the container body A, and the proximal end side of each of the locking pieces 19 is releasably locked to the vertical portion 10 side of the locking protrusions 11.

Since this device is constructed as described above, when the lid is closed, the concave portion 17 of the lid B is screwed into the neck portion 6 of the container body A using the screwing means of the male screw 7 and the female screw 16. At the final stage when the peripheral edge 14 of the lower plate 15 of the lid B comes into contact with the plate 4, the tip end side of the locking piece 19 of the lid B comes into contact with the locking protrusion 11 of the container body A, as shown by the dashed line in FIG. The locking piece 19 comes into contact with the foot of the slope 9 and moves to the top of the slope 9 of the locking protrusion 11 while resisting the elastic force. Furthermore, the fourth
When the locking piece 19 moves as shown by the solid line in the figure,
The locking piece 19 is pushed down to the vertical part 10 of the locking protrusion 11 by the elastic force, and the locking piece 19 rides over the locking protrusion 11 and is attached to the stopper protrusion 8 of the container body A and the stopper piece 18 of the lid B. At the same time as the locking protrusion 11 comes into contact with
The base end side of the locking piece 19 is locked to the vertical portion 10 side of the locking piece 19 .

Therefore, in such a closed state, the downward elastic force of the locking piece 19 causes the locking piece 19 of the lid B to close.
Since the base end side of the lid B is constantly pressed against the vertical part 10 side of the locking protrusion 11 of the container body A, the locking piece 19 will not come off from the locking protrusion 11 even with some impact, and the lid B will be prevented from returning. This can reliably prevent leakage of liquid cosmetics, etc. Moreover, the stop piece 1 provided near the recess 17 on the lower surface of the lower plate 15 of the lid B
A locking piece 19 having an arc-shaped longitudinal cross section and a groove-shaped cross-section in the transverse direction is provided near 8 and at a position opposite to this with the recess 17 as a boundary, with the distal end side open and the locking piece 19 having a groove-shaped cross section in the transverse direction. This combination of the fact that the locking pieces 19 are elastically protruded in the same direction, and that the escape hole 20 is provided in the lower plate 15 opposite to the portion of the locking piece 19 excluding the proximal end side, When the locking piece 19 is engaged or disengaged, the upper side of the locking piece 19 resists the elastic force and closes in the escape hole 20 of the lower plate 15.
This prevents the locking piece 19 from coming into contact with the lower plate 15, and not only makes the elastic action of the locking piece 19 of the lid B extremely smooth, but also prevents the locking piece 19 from coming into contact with the lower plate 15.
The repellency effect of No. 9 is also very good.

In addition, by providing the anti-slip portion 3 in which protrusions 2 are vertically connected in parallel in a substantially wave shape on the front and rear surfaces of the outer circumferential surface of the body 1 of the container body A, the body of the container body A 1 can be prevented from slipping, which not only makes handling operations extremely easy during use, but also the curved portion 12 is provided on the non-slip portion 3 of the body 1 of the container body A and on the upper front side of the exterior plate 13 of the lid B. Combined with this, it has a decorative effect and an excellent appearance. In addition, the curved portion 12 also serves to represent the front and back position of the entire container of this invention rather than the lid B.

Furthermore, on the upper surface of the lower plate 15 around the recess 17 of the lid B,
Middle reinforcing piece 21 and front reinforcing piece 2 assembled in a substantially I-shape
2. Rear reinforcing piece 23, pair of hook-shaped rear corner reinforcing pieces 2
4, together with the anti-slip portion 3 of the container body A, the strength of the container body A and the lid B is strong and extremely robust.

As explained above, according to this invention, it is possible to prevent the lid from returning and reliably prevent leakage of liquid cosmetics, etc., and the elastic action of the locking piece of the lid is smooth.
In addition, the locking piece has excellent elasticity and appearance, is extremely easy to handle during use, and the container body and lid are strong and extremely durable. It will be done.
