Description

[Detailed description of the invention] The present invention relates to containers for viscous liquid cosmetics and medicines such as creams, foundations, and ointments.
In particular, it is an object of the present invention to provide a container that can easily dispense the required amount.

The gist of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 1 is a longitudinal sectional front view showing one embodiment of the container of the present invention,
is a middle cylinder, which is provided with an upper plate part 3 equipped with a spout 2 at the upper part, a sliding ring 4 protruding from the lower periphery, and an inner plate 5 which closely slides on the inner peripheral wall 1a. The middle plate 5 is provided with a spring 6 for checking.

Reference numeral 7 denotes an outer cylinder, which is slidably installed inside the middle cylinder 1, faces the sliding ring 4, and seals the internal air chamber R.
An annular edge 8 is provided inwardly to prevent separation of the bottom portion 7a, and an intake valve 9 is provided at the center of the bottom portion 7a.

10 is a pressure expansion spring that presses the middle cylinder 1; 11 is the middle cylinder 1;
It is a cosmetic filled inside.

In the embodiment shown in the first drawing constructed as described above, by pressing down the middle cylinder 1 with a finger against the elasticity of the expansion spring 10, the shape is formed by the outer cylinder 7 and the middle plate 5. At the same time as the air in the air chamber R is compressed, the inner plate 5 is slid upward in the inner cylinder 1 by the internal pressure of the air chamber R, and as a result, the cosmetic 11 is pushed from the spout 2 onto the upper tray part 3. To be pushed out/become.

Therefore, the amount of pouring can be adjusted freely depending on the degree to which the middle cylinder 1 is pressed down, while the check spring 6 of the middle plate 5 bites into the inner circumferential wall 1a in the raised position to prevent the bottom plate 5 from descending.

Next, when the pressing force is released, the expansion spring 10 pushes up the middle cylinder 1 to its original position, but the air chamber R is expanded by the amount that the middle plate 5 is pushed up, so negative pressure is generated. Since the necessary amount of air is sucked in from the outside through the valve 9, the pressure inside the air chamber R is adjusted to be the same as the outside pressure.

Thus, in this embodiment, the required amount of cosmetics can be extruded onto the upper tray part 3 with a single touch without staining the hands.
Since the return of the middle plate 5 is prevented, a part of the cosmetic 11 that has been pushed out is prevented from being sucked into the container, which is extremely hygienic, and unlike a tube, it is also aesthetically pleasing. It is well suited to be placed on a dressing table or the like.

Next, in the embodiment shown in the second figure, the spout 2' provided in the middle cylinder 1 is beak-shaped as shown in the figure, and is directed downward, so that the required amount can be directly squeezed out onto the fingers. The inner plate 5 is designed to prevent the filled cosmetic material 11 from returning due to viscous resistance at the outlet of the pores, and the receiving ring 12 is connected to the guide tube of the outer tube 7. It fits loosely into the portion 13 and supports the lower edge 1b of the middle cylinder 1.
Of course, the inside of the air chamber R' surrounded by these is sealed from the outside air.

It should be noted that in this embodiment, the cartridge is formed by the middle cylinder 1 and the middle plate, and is replaceable with respect to the outer cylinder 7.

The embodiment shown in FIG. 2 having the above structure is used in the same pressing operation as the embodiment shown in FIG. According to the user's preference, it is convenient to be able to exchange the inner cylinder 1 with the outer shape as shown in the first figure, and in particular, the outer cylinder 7 can be shaped luxuriously to have the effect of being an ornament. It is possible.

Next, the embodiment shown in Fig. 3 is a cartridge-type container that combines the embodiments shown in Figs. 1 and 2, and has a more reliable sealing of the air chamber R''. In this case, the receiving ring 12' and the inner cylinder 1 are connected by a thread 14 to further ensure the sealing between the two.

For this screwing, the receiving ring 12' is provided with a protrusion 12a, while the outer cylinder 7 is provided with a rotation groove 7a to prevent rotation of the receiving ring 12', and the inner cylinder 1 and the middle plate 5 are It is designed so that screwing and unscrewing can be easily carried out by replacing the cartridge consisting of the cartridge.

As mentioned above, the container of the present invention prevents the contents such as cosmetics from returning due to the negative pressure inside the inner cylinder 1, so it is possible to reliably prevent the contents from being contaminated, and also to prevent the contents from being contaminated. It can be used without getting dirty, and it can be operated with just one touch by pressing down on the inner tube, allowing you to extrude just the amount you need.Unlike tube-shaped products, it has a good appearance, especially for cartridges. In the case of formal envelopes, it is possible to enhance the beauty of the outer envelope and contribute to increasing the product price.
Furthermore, the function as a whole is simple, and it can be manufactured at low cost using a resin or the like, and its practical advantages are extremely significant.
