BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a container cap which is easily and separately collected and, more particularly, to a container cap which is easily and separately collected, in which when the container cap is opened for use, a state in which the container cap is connected to a container is maintained by a display ring, and when it is required to completely separate the container cap from the container for separate collection, the display ring is simply separated by a cut part by external force without a separate tool.

2. Description of the Related Art

In general, a container in which beverage such as mineral water or liquid materials such as oil, paint and chemicals are accommodated has a protruding spout through which liquid materials are input/output. Here, a container cap configured to open/close an opening of the spout is used to suppress input/output of the liquid materials.

FIG. 1is a view illustrating a general container and a general container cap. Referring toFIG. 1, in the general container10and the general container cap20, a male screw M/S is formed on an outer peripheral surface E/S of a protruding spout of the container10and a female screw F/S is formed on an inner peripheral surface I/S of the covering cap20to correspond to the male screw M/S, so that the container10and the container cap20are screw-coupled to each other or are uncoupled from each other.

Here, the container cap20includes a display ring21caught by the spout of the container10to be prevented from being separated so as to identify whether the container10is used, and a cap body22.

Further, the cap body22and the display ring21are connected to each other along a circumference therebetween by a plurality of bridges23.

Accordingly, if the cap20is opened when a user uses the container, the bridges23are cut, and thus opening trails are generated. Here, the display ring21is separated from the cap body22and remains while being caught by the spout of the container, and the cap body22is completely separated from the container.

Meanwhile, when the container cap20ofFIG. 1is completely separated from the container10, there is possibility of contamination and concern of loss. To prevent this, a recently-developed container cap is connected to the spout of the container even when the spout of the container is opened.

Examples thereof include Korean Patent No. 10-1325850 (Packing container cap: hereinafter, referred to as “prior art 1”) and Korean Patent No. 10-1038894 (Packing container cap: hereinafter, referred to as “prior art 2”).

Referring toFIG. 2, a container cap according to the prior art includes a cap body22′ and a portion, that is, a display ring21′, fixed to a container integrally formed at a lower portion of the cap body22′.

Further, a plurality of bridges23are formed along a circumference between the cap body22′ and the display ring21′ except for a portion thereof, and a hinge25connecting the cap body22′ and the display ring21′ to each other is formed at the portion.

Further, the display ring21′ has a cut slit24formed by cutting the portion of the circumference, to define an extending length when the cap body22′ is separated from the container10.

Meanwhile, the general container cap including the above-described prior arts 1 and 2 as well as the container is separately collected after liquid materials are completely consumed and is recycled.

Further, the container10is generally formed of polyethylene phthalate (PET), and further, the container caps20and20′ are generally formed of polypropylene (PP) or polyethylene (PE).

In this way, the container and the container cap are formed of different materials, and it is preferred that, to improve recycling efficiency, the container and the container cap are collected in accordance with materials to ensure properties of the corresponding materials.

However, the container caps20and20′ according to the related art have a problem in that, because the display rings21and21′ are collected while being fixed to the container10after being used, the display rings21and21′ are recycled together with the container.

Because of this, to completely separate the container and the container cap having different materials from each other, collect the container and the container cap in accordance with materials, and individually recycle the container and the container cap, a collection worker should perform an operation of cutting and separating the display rings21and21′ from the container10by using tools such as a knife and nippers.

In this way, in the container having the container cap according to the related art, a secondary operation of cutting and separating the display rings using tools is required to separate the container and the container cap from each other in accordance with materials to recycle the container and the container cap. Further, development of a container cap which is easily and separately collected according to materials is acutely required.

BRIEF SUMMARY OF THE INVENTION

The present disclosure is conceived to solve the above-described problems, and an aspect of the present disclosure is to provide a container cap for easy separate collection, in which a display ring as well as a cap body may be completely separated from a spout of a container, so that recycling efficiency may be improved.

To achieve the above aspects, a container cap which is easily and separately collected, according to the present disclosure, may include a cap body using a screw-coupling scheme and a display ring provided below the cap body to connect one hinge and a plurality of bridges to each other, and has a loss and free rotation preventing function.

Here, the display ring may have a cut part including cut bridges formed from one end or both ends of the cut slit in a lengthwise direction of the cut slit to a lower end of the cut slit.

Further, the display ring may further have an anti-shock hole formed between an end of the cut slit and an end of the cut part, which is in contact with the end of the cut slit.

Further, a guide groove that is thinner than a thickness of the display ring may be formed in a portion of the cut part, in which the cut bridges are formed.

Meanwhile, the cut part may have a slope a at a cut slit end and is formed toward a lower end of the display ring, at which the cut slit is not formed.

In addition, the anti-shock hole of the cut part may have an interval that is larger than an interval formed by the cut slit, and an upper end of the anti-shock hole may be higher than an end of the cut slit.

In this way, a container cap which is easily separated and collected, according to the present disclosure, has an effect that a user may completely separate a spout of a container and a display ring from each other only by applying external force pulling a cap body by a cut part formed at an end of a cut slit of the display ring, so that the container and the container cap having different materials may be discriminately, easily and separately collected.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, exemplary embodiments of a container cap which is easily and separately collected, according to the present disclosure, will be described in detail with reference to the accompanying drawings.

Further, the present disclosure will be described with reference to a state in which a container having the container cap installed therein stands, that is, a state in which a spout of the container extends upward, the expression “inside” refers to a central direction of an inside of the container at the corresponding height or a portion located in the direction, and the expression “outside” refers to a direction that is opposite to the inside or a portion located in the direction.

Further, the height refers to an interval between the container including the container cap and a floor in a state in which the container stands up.

Meanwhile, in description of the present disclosure, detailed descriptions of the widely-known functions or configurations will be omitted to make the subject matter of the present disclosure clear.

FIGS. 3 and 4are perspective views illustrating a container cap which is easily and separately collected, according to the present disclosure, andFIGS. 5A, 5B and 5Care an embodiment illustrating a usage state of the container cap which is easily and separately collected according to the present disclosure.

As illustrated, a container cap100which is easily and separately collected, according to the present disclosure, may be completely separated from a container10after the container10is used, so that the container and the container cap having different materials may be separately collected and recycled.

To achieve this, the container cap100which is easily and separately collected has a cut part150including cut bridges152from one end or both ends of the display ring120in the lengthwise direction thereof to a lower end of the display ring120.

As the cut part150is formed, a user may separate the display ring120from the container without a separate tool such as a knife and nippers.

In detail, referring toFIGS. 3 and 4, the container cap100which is easily and separately collected, according to the present disclosure, is coupled to a spout of a container in a screw-coupling scheme by a male screw M/S and a female screw F/S, which is identical to the general container cap according to the related art, and has an opening/closing structure for the container spout according thereto.

In detail, the container cap100includes a cap body110separated by lifting-up in a screw-coupling scheme, and a display ring120connected to one hinge130at a lower portion of the cap body110by a plurality of bridges121.

Here, the display ring120has a cut slit140on a lower side of the hinge130, and the cut slit140is formed by cutting a partial section of a circumference (for example, a half of the circumference) of a central portion of the display ring120in the height direction thereof.

When the cap100is opened, a portion of the above-described display ring120, in which the cut slit140is formed, is divided into an upper display ring120aand a lower display ring120band, while being widened, enlarges a connection length between the cap body110and the display ring120so that the cap body110is opened while being connected to the display ring120.

Referring toFIG. 5A, a general usage state of a container cap using the above-described container cap may be identified. This corresponds to a well-known function, and thus, a detailed action relationship thereof will be omitted to make the subject matter of the present disclosure clear.

Meanwhile, the general container10and the general container cap100are manufactured of different materials, and after the container10is used, the container10and the container cap100are completely separated from each other as far as possible, so that a separate collection box may improve recycling efficiency.

To this end, the cut part150is formed downward from one end or both ends in the longitudinal direction of the cut slit140of the display ring120to a lower end thereof such that a user or a worker may completely separate the container cap100from the container10by easily applying external force without a separate tool such as a knife and nippers, as needed.

The cut part150has a cut line formed by perforating one or more holes at a portion at which the cut line is to be formed, and the cut line is formed by a plurality of cut bridges152to be cut by applying external force.

Referring back toFIGS. 3 and 4, when the cut part150is formed, the display ring120further has an anti-shock hole151formed between an end of the cut slit140and an end of the cut part150in contact with the cut slit140.

Such an anti-shock hole151serves to concentrate a direction of force applied so as not to unintentionally cut the cut part150, to the upper display ring120a, when the user opens the container cap100, that is, when the display ring120is divided into the upper display ring120aand the lower display ring120bby the cut slit140and enlarges the connection length between the cap body110and the display ring120while being widened.

It is preferred that the cut part150has a slope a at a cut slit end141and is formed toward a lower end of the display ring120in which the cut slit140is not formed. Referring toFIG. 5A, a direction of force generated when the container cap100is opened by the anti-shock hole151does not face the cut part150but faces an end of the upper display ring120adivided by the cut slit140, in the display ring120.

Further, it is preferred that the anti-shock hole151has an interval that is larger than an interval formed by the cut slit140so that the direction of force is formed upward, and it is preferred that an upper end of the anti-shock hole151is formed to be higher than an end of the cut slit140.

In addition, the cut part150is formed along a guide groove153of which a portion in which the cut bridges152are formed is thinner than the thickness of the display ring120such that the user or the worker easily separate the container cap100while holding the cap body110and applying force.

As described above, the cut part150formed in the container cap100which is easily and separately collected, according to the present disclosure, is formed in consideration of the thickness and the strength of the container such that there is no fracture when the container cap100is coupled to the container10or the container10is opened, and when the user wants to completely separate the container cap100from the container10, the design of the cut part150is sufficiently considered such that the cut part150may be cut by force pulling the cap body110.

Next, a usage state of the container cap100which is easily and separately collected according to the present disclosure will be described with reference toFIGS. 5A, 5B and 5C.

As described above, the container cap100which is easily and separately collected includes a cap body110and a display ring120formed at a lower portion of the cap body110by connecting the hinge130and the bridges121to each other.

Further, the cut slit140is formed by cutting a portion of a circumference of a central portion of the display ring120in the height direction thereof, and the cut part150including the anti-shock hole151, the cut bridges152and the guide groove153is downward formed at an end of the cut slit140.

First, referring toFIG. 5A, the user grips and rotates the cap body110to open the container10. Here, the bridges121are cut and separated, and while the display ring120is fixed to the spout of the container, the cap body110is lifted up in a screw-coupling scheme, so that the spout of the container is opened.

Here, the upper display ring120adivided by the cut slit140increases the connection length while being connected to the cap body110, so that the cap body110may be opened.

Meanwhile, the cut part150including the cut bridges152formed to a lower end of the display ring120is formed at one end or both ends of the cut slit140in the lengthwise direction of the cut slit140to a lower end of the cut slit140, and force applied to the increased connection length of the upper display ring120ais not headed to the cut part150by the anti-shock hole151of the cut part150so that the cut part150is not cut and the shape of the cut part150is maintained.

It is preferred that the cut part150has a slope a at the cut slit end141and is formed toward a lower end of the display ring120in which the cut slit140is not formed, and the anti-shock hole151has an interval that is larger than an interval formed by the cut slit140. It is preferred that an upper end of the anti-shock hole151is formed to be higher than an end of the cut slit140.

Meanwhile, as needed, the cut part150may be vertically formed at the cut slit end141toward a lower end of the display ring120, and it is apparent that this may be changed depending on the manufacturing and the design of the container cap100.

Referring toFIG. 5B, after the container is used, the user or the worker completely separates the container cap100from the container10.

To this end, the user holds the cap body110and bends the display ring120in an opposite direction while the display ring120passes through the spout of the container.

Here, the cut part150is formed in a direction in which force is applied, and thus, the cut bridges152are separated and cut by external force.

Further, as illustrated inFIG. 5C, the container cap100is completely separated and escapes from the container10, and the container10and the container cap100having different materials are separately collected.

A usage state of the container cap100described inFIGS. 5A to 5Cis merely an embodiment for easily and completely separating the container cap100from the container10using the lowest force, and it is obvious that the user may pull the cap body110of the container cap100in a lateral direction without bending the cap body110of the container cap100so that the container cap100and the container10may be separated by the cut part150.

The above-described present disclosure may be variously substituted, modified and changed by those skilled in the art to which the present disclosure pertains without departing from the technical spirit of the present disclosure, so that the present disclosure is not limited to the above-described embodiment and the accompanying drawings.
