BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a porous honeycomb structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a porous expanded body and a cap including the same. More specifically, the present invention relates to a porous expanded body for extracting a liquid content contained in a vessel by a foam and a cap including the porous body.

Containers containing cosmetics such as lotion, shampoo, rinse and liquid soap contain the contents in the filling space and introduce outside air to reduce the volume of the filling space and to allow the air to flow out. Or a type in which the contents are extracted by putting the pump without reducing the volume of the filling space.

There are a number of product groups that should be used as a reward (foam, bubble, foam, etc.) when extracting contents from a container containing contents. For example, it is effective to use the liquid content such as foam soap, shaving cream, etc. as a foam rather than extracting it directly out of the container.

Conventional liquid container closure is solved by spraying the liquid contained in the container in the form of a foil, and placing the mesh or mesh on the spurting passage so that the liquid fluid is blown out with the air by the force of the flowing air.

However, the cap of the existing liquid container is formed in different forms depending on the structure of the passage forming the air and the contents, the quality and the viscosity of the contents, the material and structure of the container, and the performance of the pump in ejecting the liquid contained in the container. . As a result, it is difficult to form a stable and stable reward through a mesh or mesh, and there is room for improvement.

On the other hand, the types of contents are continuously increasing. In addition, the quality of the reward is required to be delicate, constant and stable, and at the same time, it is required to be structurally simple, low in failure, and good in durability. This trend is expected to continue for a long time.

The present invention extracts the contents constantly and stably through the porous body in extracting the contents as a foam. By using the porous foam body, the contents of the liquid phase can be finely extracted in the form of foam, bubble, foam or the like, as compared with the case of using a foam body such as a net, mesh or the like.

In order to extract the contents of the liquid phase in the form of a foam, the porous foam according to the embodiment of the present invention may use a sponge or the like having high hydrophilicity among the porous foam body. The porous foam body causes bubbles in the liquid contents, It can be applied for various purposes.

The plug including the porous expanded body can provide a plug with high performance and high reliability with low failure and good durability.

The porous expanded body according to the embodiment of the present invention has hydrophobicity so that the contents of the liquid phase to be jetted can be decomposed well and the fine porous body can be finely extracted in the course of foam, bubble, foam and the like.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing a porous covering and a cap structure according to an embodiment of the present invention.

As shown in Fig. 1, the porous covering 120 has a shape having an area and a height that can be installed in a contents outlet such as a container. Preferably, the area of the porous body 120 is filled with the outlet, and the height of the outlet is greater than 1/3 of the height of the outlet in proportion to the height of the outlet. However, it is not necessarily limited thereto.

2 shows an example in which the porous body 120 is a true-type body, but there is no limitation.

The porous body 120 may be formed of a hydrophobic resin such as silicone or epoxy resin. The porous body 120 may also be made of a sponge or a superabsorbent resin having hydrophilic properties.

The swollen body may be any one of a porous synthetic resin, a porous natural rubber, and a porous metal, or may be a porous swollen body in which two or more of these are combined. PP, PE, PS, and the like, and compounds thereof. As the hydrophilic capsule, a polyurethane material may suitably be used.

The envelope may be arranged in a single layer or in a plurality of layers when it is installed in a discharge port of a container or the like, and in this case, it is also possible to freely adjust the levitation state of the contents by controlling the porosity of the porous envelope.

The envelope provided at the outlet of the container or the like may include a layered structure arranged in a different material. For example, it is possible to freely adjust or select the foam state of foam or the like depending on the contents by placing a polyurethane foam having a high hydrophilic property on the bottom and a porous foam made of a porous metal having high durability on the bottom.

The porous honeycomb body provided at the discharge port may have a laminated surface. It is advantageous to arrange it in a multi-layered structure when the layered surface is included. This can be satisfied by treating the surface and the floor with a flat surface.

Fig. 2 is a plan view, Fig. 2 (b) is a front view, Fig. 2 (c) is a bottom view, and Fig. 2 (d) is a sectional view taken along the line C-C in Fig. 2 (b).

As shown in Fig. 2, a hydrophobic resin can be used as the porous body 120. The sponge itself has a porous property with hydrophilic properties. Preferably, the material of the sponge is selected from porous polyurethane, polyethylene, polypropylene, polystyrene or porous natural rubber. However, it is not limited thereto.

A polyurethane sponge or porous natural rubber is classified as a foam having a force of returning to its original state when pressed and released, and a polyurethane sponge and a natural rubber sponge are also included in the foam. The elastic recovery is due to almost all of the void space in the sponge being connected, filling the gap when the air escapes when it is restored to its original state, which serves as an open-cell foam.

Therefore, when the content of the liquid phase passes through a vaporizer such as a polyurethane porous sponge or the like, the content of the liquid phase is changed into a foam state by bubbling, bubbling, or the like due to the role of the foam of a sponge having high hydrophilicity.

As a result of the test, the existing method of reapplication is to pass the contents through a mesh or mesh and apply a method to induce rewards in the process. However, the quality of the reaping depends on the strength of the contents, the type and quality of the contents, And the stability was also reduced. In the case of using the porous covering 120, the influence of the kind and quality of the content was less influenced by the degree of rejuvenation, and the influence of the viscosity and the like was smaller than in the case of using a mesh or mesh. It is predicted that this is due to hydrophilic porous scales.

As shown in FIG. 1, the cap including the porous covering according to the embodiment of the present invention may include the porous covering 120 as a receptacle, and may include a filling space of the container B containing the contents, And an intake / exhaust unit 160 which is connected to the intake /

The mixing unit 130 is coupled with the intake and exhaust unit 160 to mix the contents with the air.

And an outlet 112 for discharging the contents of the foam passing through the porous body 120. The porous body 120 may be formed of a porous material, The plug including the porous expanded body is not limited to the plug as shown in Fig. 1, and may include various plug structures.

The cap including the porous covering according to the embodiment of the present invention may include a cover over the cap, and may include a cap (not shown) that can be opened and closed.

The threaded portion of the container may be coupled or fitted in a threaded portion formed in the neck portion of the conventional container, and a peripheral wall surface forming the coupling groove 102 for threaded engagement may be formed with threads threadably engaged with the neck thread of the container But it is not limited thereto, and various combinations and combinations can be selectively applied.

3, the cap 100 includes a first housing channel 103 and a second housing channel 104 that are coupled to the mixing unit 130, and a third housing 104, in which the porous swing body 120 is seated, And an outlet hole 106 that is in communication with the first and second housing passages 103, 104, and 105, as shown in FIG. The cap 100 can be made by synthetic resin injection molding, and the cap forms the overall contour of the cap.

The cap 100 is formed with a stopper 101 protruding in the horizontal direction on the inner wall surface of the outflow hole 106 to prevent the flow and deviation of the porous foam body 120 and securely support the porous foam body 120 It will help.

As shown in FIG. 5, the cover housing 110 has a structure including a lattice passage portion 111 for branching the contents of the foam passing through the porous body 120. An outlet 112 is formed in the lid flow passage 111 of the cover housing 110 to flow out the contents.

The lattice channel portion 111 and the outlet port 112 formed by the lattice channel portion thereof divide the liquid content that is ejected in the form of foam while passing through the porous foam body 120 by dividing the liquid content by the number of lattices, The use condition of the battery pack is changed to a good condition. For example, although the foamed contents can be aggregated, they do not clump in the process of passing through the outflow opening 112 of the lattice channel portion 111, so they are extracted in a state suitable for use.

A locking protrusion 114 is formed on the inner wall surface of the cover housing 110 to be coupled to the mixing portion 130. A locking protrusion 137 corresponding to the locking protrusion 114 is formed in the mixing portion 130, When combined, one-touch coupling is possible without using a separate fixing member.
