Cover assembly enable to mix interior material at opening

A cover coupled with a container that allows contents thereof to be mixed when the cover is opened, is provided. The cover includes a cover body and a packing member. The cover body consists of a cylinder-shaped shaped receiving wall integrally projected from the bottom to for a receiving space. The packing member has a blocking wall, the first support wall, the second support wall, and bridges. The first support wall extends from the blocking wall and is forcibly fitted in the inside of the receiving wall. The second support wall is forcibly fitted in the inside of the lateral wall of the container and the bridges are formed at a constant interval to connect the first support wall and the second support wall. Since the cover body and the packing member are coupled in the shape of an assembly, a coupling process with the container can be separately performed and thus assembling efficiency improves.

TECHNICAL FIELD

The present invention relates to a cover that can allow different contents to be mixed when the cover is opened, and more particularly to a cover capable of improving assembling efficiency by allowing the cover to be coupled with a container with a cover body and a packing member assembled in advance. Also, the present invention relates to a cover having a simple structure and allowing a packing member to be attached to a container and remain in or to be attached to the cover and detached together with, if necessary, when the cover is opened.

BACKGROUND ART

A container containing beverage or cosmetics generally includes one type of content. Therefore, the container has a simple structure consisting of a container having a receiving space for receiving such a content and a cover for sealing the container.

However, as functional beverage or cosmetics appear, a necessity for a container structure allowing different contents to be mixed when the drinking water or cosmetics are used by a consumer has emerged.

The structure proposed by such a necessity will now be described. A packing member is generally used so as to store a content added to the content of the container. When a cover sealing the container is opened, the packing member is detached from the container and falls into a receiving space inside the container.

When the packing member exists inside the container, it is problematic that many troubles are caused in using the contents of the container. Also, since the packing member fails to subside to the lower portion of the container in the case of sol-type contents, the packing member may block a path through which the content flows out of the container.

Also, in the case of beverage, there is a danger that the packing member gets into the mouth of a user together with the beverage.

Though constructions for solving the above problems have been suggested, the constructions are very complicated and thus lots of parts are used, which increases manufacturing costs.

Also, in association with the complicated construction, assembling efficiency deteriorates because the assembling is performed in an order that the packing member is mounted on the container first and then the cover is coupled thereto.

DISCLOSURE OF INVENTION

Technical Problem

An object of the present invention is to provide a cover for preventing a partition member from getting into a receiving space inside a container when the cover of the container is opened, the partition member partitioning at least two different contents.

Another object of the present invention is to provide a cover for improving assembling efficiency by allowing the cover to be assembled to a container after a cover body and a packing member are incorporated into one assembly.

A further object of the present invention is to provide a cover capable of reducing manufacturing costs by providing a simple structure.

Technical Solution

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, there is provided a cover including: a cover body having a bottom and a lateral wall integrally formed at edges of the bottom and a cylinder-shaped receiving wall integrally projected from the bottom to form a receiving space for receiving contents in an inside of the lateral wall; and a packing member having a blocking wall for closing the receiving space, a first support wall extending from the blocking wall and forcibly fitted in an inside of the receiving wall, a second support wall forcibly fitted in an inside of a neck of a container, and bridges formed at a constant interval to connect the first support wall with the second support wall.

According to another aspect of the present invention, there is provided a cover including: a cover body having a bottom and a lateral wall integrally formed at edges of the bottom, and having a cylinder-shaped receiving wall integrally projected from the bottom to form a receiving space for receiving contents in an inside of the lateral wall, and the cover body having a bent portion formed at a predetermined position of the lateral wall and bent in a step shape; and a packing member having a blocking wall for closing the receiving space, a first support wall extending from the blocking wall and forcibly fitted in an inside of the receiving wall, a second support wall forcibly fitted in an inside of a neck of a container, and bridges formed at a constant interval to connect the first support wall with the second support wall, a sealing member fitted between the bent portion and an end of a container along an outer periphery of the second support wall being projected from a predetermined position of the second support wall.

According to further another aspect of the present invention, there is provided a cover including: a cover body having a bottom and a lateral wall integrally formed at edges of the bottom and a cylinder-shaped receiving wall integrally projected from the bottom to form a receiving space for receiving contents in an inside of the lateral wall; and a packing member having a blocking wall for closing the receiving space, a first support wall extending from the blocking wall and forcibly fitted in an inside of the receiving wall, a second support wall forcibly fitted in an inside of a neck of a container, and bridges formed at a constant interval to connect the first support wall with the second support wall, a hooking protuberance being formed at an end of the second support wall, a guide groove that has a predetermined width and depth being formed to a height direction in an inside of the lateral wall of the cover body, the guide groove facing the hooking protuberance such that movement of the hooking protuberance is restricted by the guide groove.

According to yet another aspect of the present invention, there is provided a container assembly including: the above-described cover; and a container coupled with the cover.

The blocking wall may be inclined to have an apex in an inside of the receiving space and the receiving wall is defined to form an acute angle toward the receiving space with respect to the bottom.

Advantageous Effects

According to the present invention, since the packing member does not fall into the inside of the container when the cover is separated from the container, the container is convenient to use, and particularly, in the case where the present invention is applied to a container for beverage that a child drinks, there is no possibility that the packing member falls into the throat of a child, so that safety can be secured.

Also, the cover body and the packing member are coupled with each other in the form of an assembly first and then a coupling process with the container can be separately performed, so that assembling efficiency improves.

Also, since the present invention has a simple structure consisting of the cover body and the packing member, a manufacturing cost is lowered.

BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment

FIG. 1is a partially cut-off exploded perspective view of a cover according to one embodiment of the present invention andFIG. 2is a sectional view illustrating the cover ofFIG. 1is coupled with a container.

A cover body100includes a bottom and a lateral wall integrally formed at the edges of the bottom and includes a cylinder-shaped receiving wall110integrally projected from the bottom of the cover body100to form a receiving space112for receiving contents in the inside of the lateral wall.

Though the lateral wall of the cover body100is formed to have a bent portion124bent in a step shape, the bent portion has been added to describe a preferred shape, so the bent portion don't need to be necessarily provided.

The height of the receiving wall110is not limited but it is not desirable that the height of the receiving wall110is projected further than the cover body100. Also, referring toFIG. 3, the receiving wall110can be formed to make an acute angle ? toward the receiving space112with respect to the bottom of the cover body100and can be inclined to have constant restoring force as illustrated by an arrow A.

The packing member200constitutes a cylinder shape as a whole and includes a blocking wall210for closing the receiving space112formed by the receiving wall110, a first support wall212extending from the blocking wall210and forcibly fitted in the inside of the receiving wall110, the second support wall220forcibly fitted in the inside of a neck of the container, and bridges230formed at a constant interval to connect the first support wall212with the second support wall220.

The blocking wall210has a funnel shape inclined to have an apex in the inside of the receiving space112and can allow the contents received in the receiving space112to slide down by a weight of their own.

Forming the bridges230at a constant interval is intended for providing paths through which the contents received in the receiving space112can pass and fall into the inside of the container.

The outer diameter of the first support wall210can be the same as or greater than the inner diameter of the receiving wall110so that the first support wall210may be forcibly fitted in the receiving wall110. Likewise, the outer diameter of the second support wall220can be the same as or greater than the inner diameter of the neck of the container so that the second support wall210may be fitted in the neck of the container.

At this point, it is possible to allow the packing member200to be attached to the container and remain thereon when the cover is separated from the container by making a coupling degree between the second support wall220and the neck of the container larger than a coupling degree between the first support wall210and the receiving wall110. For that purpose, as described above, dimension can be adjusted or the area of the coupled portion can be adjusted.

The height of the second support wall220may extend to contact the inside of the lateral wall of the cover body100as illustrated inFIG. 1, or may be also made short so as not to contact the inside of the lateral wall of the cover body100as illustrated inFIG. 4.

A sealing member222fitted between the bent portion124formed in the lateral wall of the cover body100and the end of the container can be projected from a predetermined position of the second support wall220along the outer periphery of the second support wall220.

The sealing member222is formed as described above, so that airtightness can improve when the cover is coupled with the container.

In operation, the receiving space110is filled with contents by a content-supply device (not shown) with the cover body100turned over. The contents may be used in the form of powder, a tablet, or liquid.

Subsequently, the packing member200is picked up using an appropriate jig (not shown) and coupled with the cover body100.

Referring toFIG. 2, the first support wall212gets into the receiving space112in the inside of the receiving wall110and forcibly fitted in the receiving wall110. At this point, as described above, when the receiving wall110is formed to make an acute angle ? toward the receiving space112with respect to the bottom of the cover body100, the first support wall212is firmly sealed and fixed by restoring force of the receiving wall110after forcibly fitted in the receiving wall110. In that case, if necessary, the end of the receiving wall110can be formed in a taper shape to allow the first support wall212to be swiftly fitted in the receiving wall110.

Also, in the case where the second support wall220extends to contact the inside of the lateral wall of the cover body100, a coupling state can be maintained more firmly by the coupling between the first support wall212and the receiving wall110and the coupling between the second support wall220and the lateral wall of the cover body100. Particularly, in this case, leakage of the contents can be prevented even though the coupling between the first support wall212and the receiving wall110is loosened.

An assembly in which the cover body100is coupled with the packing member200as described above is coupled with the container300.

At this point, the second support wall220is forcibly fitted in the inside of the lateral wall of the container300and a coupling degree Pa between them is greater than a coupling degree Pc between the first support wall212and the receiving wall110. Also, in some cases, the coupling degree between the second support wall220and the inside of the lateral wall of the container300is greater than the sum of the coupling degree Pc between the first support wall212and the receiving wall110and the coupling degree Pb between the second support wall220and the lateral wall of the cover body100.

In the case where the sealing member222is provided, the sealing member222is interposed between the bent portion124and the end of the container300to improve airtightness.

Since the cover body100and the packing member200are coupled in the form of an assembly first and then a coupling process with the container can be separately performed, assembling efficiency improves. Particularly, since the present invention has a simple structure consisting of the cover body and the packing member, a manufacturing cost is reduced.

When the cover body100is separated from the container300in the coupling state, since the coupling degree Pa between the second support wall220and the lateral wall of the container300is greatest, the cover body100is raised with respect to the container300and the coupling between the first support wall212and the receiving wall110is released, and the contents received in the receiving space112flow down from the blocking wall210and fall into the inside of the container300through spaces between the bridges230.

When the cover body100is completely separated from the container300, only the packing member200is attached to the container300and remains thereon.

Second Embodiment

FIG. 5is a sectional view illustrating another embodiment of the present invention.

The second embodiment illustrates a construction in which a packing member200is detached with being attached to a cover body100when the cover body100is separated from a container300.

That is, a hooking protuberance224is projected from the end of the second support wall220and a guide groove128having a predetermined width and depth and facing the hooking protuberance224is formed in the inside of the lateral wall of the cover body100.

Therefore, the hooking protuberance224is restricted in its movement by the guide groove128. When the cover body100is detached from the container300, the packing member200is also detached from the container300with the hooking protuberance224hooked at the guide groove128.

Third Embodiment

FIG. 6is a sectional view illustrating yet another embodiment of the present invention.

In the third embodiment, a through hole102for communicating with a receiving space112is formed in the bottom of a cover body100and the through hole102is sealed using a sealing member150.

In the third embodiment, the sealing member150includes a holding part151and a sealing part152having different diameters, respectively, and a support groove104is formed around the entry of the through hole102in response to the edge of the sealing part152so that the sealing member150may form the same surface as that of the cover body100.

According to the third embodiment, with the packing member200coupled with the cover body100already, a receiving space110is filled with contents from the upper portion of the cover body100and then the cover body100can be sealed using the sealing member150.

Though the present invention has been described mainly for the preferred embodiment thereof, various changes and modifications would be obvious to those skilled in the art.

For example, the receiving wall may be formed in a cylindrical shape or a polygonal box shape and the number of the bridges may be appropriately selected.

Although the preferred embodiments of the present invention have been disclosed for illustrative purpose, those skilled in the art will appreciate that various modifications, additions and substitutions can be made without departing from the scope and spirit of the invention as defined in the accompanying claims.
