Description

Cap for containers that can be collected separately from the container {BOTTLE CAP}

The present invention is a cap for a container that is not segregated by being bound to a spout of a liquid container in which a container, particularly edible oil, soy sauce, sesame oil, etc. is stored, by separating the cap from the spout of the container when the container and the cap are of different materials. To separate the container and the cap so that they can be separately collected, the skirt portion is provided with a content outlet and is connected to the upper portion of the skirt portion, which is extrapolated to the spout portion of the container and has a locking projection for preventing separation from being engaged with the binding projection of the spout portion on the inner circumferential surface. A cap body including one upper surface portion; A cap cutting means including a first cut groove formed concave vertically and vertically on one inner circumferential surface of the skirt portion, and a second cut groove connected to an upper end of the first cut groove and recessed along an inner circumferential surface of the corner portion of the cap body; Including, it relates to a cap for a container that can be separated from the top portion of the container by cutting the upper surface portion from the skirt portion by using the first cut groove and the second cut groove.

Various containers are combined with a cap that allows the contents to be easily discharged while sealing the inside of the container.

Among these caps for containers, containers that contain contents used little by little over a period of time, such as cooking oil, soy sauce, sesame oil, etc., are equipped with a cap that can be opened and closed in a hinged manner.

These caps for liquid containers secure the airtightness in the container during use and storage, and at the same time, when used, the cap is released from the container to prevent the liquid contents from leaking between the spout and the cap of the container. Unlike other caps, the caps are produced and sold in one piece by binding the caps to the spout of the container by means of press-fitting.

However, in general, the container and the cap may be made of different materials for reasons such as manufacturing cost reduction of the container itself.

For example, the container of the soy sauce bottle is made of PET material, and the cap of the soy sauce bottle is made of PE material, or the container of the oil bottle is made of cans such as iron, and the cap of the oil bottle is sometimes made of PE material.

In the liquid container, the cap is integrally fixed to the muzzle of the container, and while securing the sealing property in the container, the cap itself can be easily opened, and when disposing of the used container, dissimilar containers and caps are respectively disposed. There is a disadvantage in that it is difficult to separate and it is difficult to separate and collect by material.

Of course, it is possible for the user to separate the container and the cap separately using a tool with a little effort when disposing of the garbage, but it is very difficult and cumbersome for a woman or the elderly to separate and separate the integral cap from the container. It is common to discharge without separation.

Therefore, the garbage disposal company needs to separate and remove the caps of different materials from the collected containers, so it takes a lot of time to process the garbage and there is a problem in that the cost burden increases.

For reference, related prior arts include Patent Publication No. 10-2003-0015167, Patent Publication No. 10-2014-0147778, and Patent Publication No. 10-2015-0106185.

Accordingly, the present invention has been devised to solve the problems as described above,

The cap is integrally fastened so as not to be separated from the container, especially the liquid container where edible oil, soy sauce, sesame oil, etc. are stored, and it is possible to ensure the tightness in the container and prevent the cap from opening. The first cutout groove and the second cutout groove are recessed in the inner side of the skirt portion of the cap body and the corner of the cap body so that it can be easily separated and discharged so that the container and the cap made of different materials can be separated and collected. It is an object to provide a cap for a formed container.

In order to achieve the above object, the container cap according to the present invention,

In the cap for the container is not separated by binding to the spout of the container,

A cap cutting means including a first cut groove formed concave vertically and vertically on one inner circumferential surface of the skirt portion, and a second cut groove connected to an upper end of the first cut groove and recessed along an inner circumferential surface of the corner portion of the cap body; Including,

It characterized in that the cap can be separated from the spout portion of the container by cutting the upper surface portion from the skirt portion using the first and second cut grooves.

It is characterized by.

And in order to achieve the above object, in the container cap according to the invention,

The cap separating means further includes a bending groove formed concave in the vertical direction in the vertical direction at the point opposite to the first cutting groove on the other inner circumferential surface of the skirt portion,

When the skirt portion is cut, the skirt portion may be folded starting from the bending groove.

Also in the cap for a container according to the invention,

The second cutting groove is characterized in that the cutting start portion and the cutting end portion are not connected to each other in a circular shape, but the cutting end portion is positioned at a point biased in the direction in which the skirt portion is cut through the bending groove.

Furthermore, in the cap for a container according to the present invention,

The first cut-out groove is formed in a wedge shape with an outer edge angled outward,

The bending groove is characterized in that the outer edge portion is formed in an arc shape rounded outward.

The container cap according to the present invention,

The first and second cutout grooves connected to each other in the vertical and vertical directions of the cap body and the circumferential direction of the corner portions of the cap body are provided, and after use, hold the cap of the cap and tear off the skirt portion from the upper surface to form an integrated cap. Can be more easily separated from the spout of a liquid container in which containers, especially edible oil, soy sauce, sesame oil, etc. are stored, to facilitate separate collection and collection of containers and caps made of different materials, separating containers and caps during garbage disposal. Since it does not require work, it reduces the time required for waste disposal and reduces the cost of additional work.

A bending groove is provided at an opposite side of the first cutting groove, and when the skirt portion of the cap body is torn off, the skirt portion is folded in the cutting direction to facilitate separation,

The cutting end portion of the second cutting groove passes through the bending groove and is located at a point biased in the direction in which the skirt portion is cut, so it is convenient because the skirt portion and the upper surface portion are not completely separated.

The first cutting groove is suitable for cutting the skirt portion, while the bending groove allows the skirt portion to be folded without being cut, so that even a weak woman or the elderly can easily remove the cap and discharge it.

When the cap is coupled to the container by pressing or the like, there is an effect that can prevent the breakage of the cutting groove due to the displacement of the shape of the cap itself, deformation of the locking projection, and the like.

In the description of the cap for a container according to the present invention, for convenience, specifying an approximate direction standard that is not rigid with reference to FIG. 1, determines the direction of gravity acting downward, and determines the up, down, left, and right directions, and other drawings. In the detailed description and claims of the related invention, the direction is specified and described according to this standard, unless otherwise specified.

Hereinafter, a cap for a container according to the present invention will be described with reference to the accompanying drawings.

1 to 3, the present invention relates to a cap for a container that is not separated by being bound to the spout 11 of the container 10, and the cap is largely not separated from the spout 11 of the container. It includes a cap main body 20 to prevent the binding, and the cap separating means 30 to remove the cap from the container after use.

The cap body 20 is extrapolated to the spout portion 11 of the container, and the skirt portion 21 having a locking protrusion 22 for separating prevention that is engaged to the binding protrusion 12 of the spout portion 11 on the inner circumferential surface , It is connected to the upper end of the skirt portion 21 and includes an upper surface portion 23 having a content discharge port 24.

As described above, the cap of the present invention is a non-separable coupling during use in the spout 11 of a liquid container in which a container, in particular, edible oil, soy sauce, sesame oil, etc. is stored, is screwed to the spout 11 of the container There is a difference from a typical cap that is combined in a way.

Accordingly, in order to fix and couple the cap to the spout portion 11 of the container, a binding projection 12 protrudes on the outer circumferential surface of the spout portion 11, and the binding projection 12 on the inner circumferential surface of the skirt portion 21 of the cap. ) Is provided with a locking projection (22) protruding from a lower height,

When the cap body 20 is forcibly fitted into the spout portion 11 of the container by press-fitting or the like, the locking protrusion 22 is fixed while being caught by the lower end of the binding protrusion 12, sealing in the container of the cap and Separation prevention is achieved.

Such a cap is connected to close the outlet 24 to prevent leakage of the contents before use, and a stopper portion 26 having a ring portion 26a formed thereon is connected, and hinged on one side of the cap body 20. A lid 27 connected to the branch 27a is provided,

After the initial purchase of the product, when the stopper 26 is opened with the hook 26a, the outlet 24 is opened, so that it can be used along the contents through opening and closing of the lid 27.

At this time, the opening and closing method and structure of the lid 27 and the detachable structure of the stopper 26 may be variously changed according to the type of container used, and such structural changes are less relevant to the core of the present invention. In the specification, detailed descriptions thereof are omitted.

As described above, the cap integrally bound to the spout 11 of the container needs to be separated from the container and then discharged when the container and its material are different, and the conventional integrated cap has a separate separating means. Since it is not provided, it is very difficult and cumbersome for a general user, such as a home or restaurant, to separate and discharge the cap, and most of the containers are discharged as garbage while the cap is attached to the container, and then separately processed by the garbage disposal company. There is a problem that needs to be separated.

Accordingly, the present invention is characterized in that even without using a tool without a separate operation, the female or the elderly who have weak force includes a cap separating means 30 for easily separating the cap from the spout 11 of the container. .

Specifically, the cap separating means 30 is connected to the upper end of the first cut-out groove 31 and the first cut-out groove 31 formed concave vertically in the vertical direction on one inner circumferential surface of the skirt portion 21. It includes a second cutting groove 32 formed concave along the inner peripheral surface of the corner portion 25 of the cap body 20.

The first cut-out groove 31 is for easily forming a thin portion of the skirt portion 21 to be easily cut, and there is no restriction on the position, but the hinge portion ( On one side of 27a), more preferably, the skirt portion 21 is provided on the same line up and down with the side end portion of the hinge portion 27a located in the direction opposite to the direction C in which the skirt portion 21 is cut (ie, torn).

The first cutting groove 31 is formed from the lower end of the skirt portion 21 to the upper corner portion 25, holding the lid 27 and twisting the hinge portion 27a with an axis to press the first cut. The portion where the groove 31 is formed is cut so that a portion of the skirt portion 21 is torn up and down.

The second cutting groove 32 is for forming a thin portion of the connecting portion of the skirt portion 21 and the upper surface portion 23, that is, a part of the corner portion 25 so that it is easy to cut, and the second cutting groove 32 The cutting start portion (C1) of the first cutting groove 31 is connected to the upper end of the corner portion 25, the second cutting groove 32 is provided.

Therefore, after tearing the skirt portion 21 using the first cut groove 31, if the skirt portion 21 is continuously pulled in the cutting direction C, the portion where the second cut groove 32 is formed is cut and the skirt portion is cut. (21) and the upper surface part 23 are separated from each other, and when the second cutting groove 32 is cut to a predetermined length or more, the separated skirt part 21 is loosened at the spout part 11 of the container and the binding projection ( 12) As the engagement between the locking projections 22 and the engaging projections is released, the cap can be easily removed and removed from the container.

Furthermore, the cap separating means 30 further includes a bending groove 33 concavely formed vertically and vertically at a point facing the first cutting groove 31 on the other inner circumferential surface of the skirt portion 21,

When the skirt portion 21 is cut, it is characterized in that the skirt portion 21 can be folded in the cutting direction C starting from the bending groove 33.

The bending groove 33 is formed from the lower end of the skirt portion 21 to the upper corner portion 25 as in the first cutting groove 31, so as to form a part of the thickness of the skirt portion 21 thin , However, the first cut groove 31 is formed to have a thickness that is thin enough to cut the skirt portion 21 completely, whereas the bending groove 33 does not cut the skirt portion 21 completely and the bending groove 33 ) Is a difference in that the skirt portion 21 is formed to have a relatively thick thickness such that it can be folded.

That is, the bending groove 33 is formed to be shallower in depth than the first cutting groove 31 (and the second cutting groove 32) (for example, the first cutting groove 31 (and the first cutting groove 31) 2 If the thickness of the skirt portion 21 in which the cutting groove 32 is formed is approximately 0.3 mm, the thickness of the skirt portion 21 in which the bending groove 33 is formed becomes approximately 0.8 mm.).

The reason that the bending groove 33 is provided on the opposite side of the first cutting groove 31 is when cutting and tearing off the skirt portion 21, if the tearing length is too long, the pulling force is applied to the skirt portion 21. This is to prevent the excessive transmission of the cap, which is not properly transmitted.

In addition, to ensure the cutting of the first cutting groove 31 and the cutting groove of the bending groove 33 more reliably,

The first cut-out groove 31 is formed in a wedge shape with an outer edge angled outward,

The bending groove 33 is characterized in that the outer edge portion is formed in an arc shape rounded outward.

That is, the inner surface of the first cutting groove 31 is formed of a wedge-shaped square portion 31a, whereas the inner surface of the bending groove 33 is formed of a rounded curved portion 33a, to tear off the cap When bent, it prevents the bent groove 33 from being torn and cut.

At this time, when the direction in which the square portion 31a protrudes in a wedge shape is formed in the cutting direction C, the skirt portion 21 can be easily cut with less force.

In addition, in the second cutting groove 32, the cutting start portion C1 and the cutting end portion C2 are not connected to each other in a circular shape, but the cutting end portion C2 passes through the bending groove 33 and the skirt portion ( 21) is located at a point biased in the direction of cutting.

That is, when the second cutting groove 32 is formed in the entire circumference of the corner portion 25, the skirt portion is cut while the second cutting groove 32, that is, the entire corner portion 25 is cut off when the cap is removed. (21) and the upper surface portion 23 may be completely separated. Thus, when the skirt portion 21 and the upper surface portion 23 are completely separated, the separation and discharge operation becomes cumbersome, so the second cutting groove 32 is a corner portion ( It is formed with a length of more than half compared to the entire circumference of 25), so that when the cap is separated and removed, the skirt portion 21 and the top portion 23 are collected separately and can be discharged together.

At this time, the length (L) of the entire section of the second cutting groove 32 is approximately 200 to 220 ㅀ in the cutting direction (C) of the skirt portion 21 with the cutting end portion C2 based on the cutting start portion C1. It is advantageous to be formed to be located in the inner portion, the cut cap is more easily separated from the spout (11).

According to the present invention of this configuration, even if the cap is integrally coupled inseparably from the spout 11 of the container by a method such as indentation rather than a screw fastening method, the different types of caps and containers can be separated and discharged separately. Accordingly, it is possible to provide a reduction in waste disposal time and a cost reduction effect by eliminating the need to separate the cap and the container during waste disposal.

On the other hand, the first cutting groove 31 and the bending groove 33 are formed in the vertical direction of the skirt portion 21, so that the middle part of the locking projection 22 is traversed up and down.

When a part of the locking protrusion 22 is removed in this way, when the cap is bound to the spout 11 of the container, both ends of the first cutting groove 31 and the bending groove 33 are opened so that the cap body 20 It may be loosely coupled, or the cut portion of the locking projection 22 is crushed, the shape is deformed and the sealing property may be deteriorated.

In particular, in the case of a plastic synthetic resin cap, since the shape of the locking projection 22 is not crushed after being pressed, the binding force and sealing properties are maintained, so it is very important to maintain the shape of the locking projection 22 during the coupling of the cap.

Accordingly, the present invention prevents the shape collapse of the engaging projection 22 when the cap is engaged, and the shape retaining member 40 that enables the functions of the first cutting groove 31 and the bending groove 33 to be intact after being engaged. It further includes.

As shown in Figure 4, the shape-retaining member 40 is made of a shape corresponding to the first cutting groove 31 and the bending groove 33, the first cutting groove 31 and the bending groove 33 By being forced into,

It has a gripping portion 42 exposed to the lower portion of the skirt portion 21 at the lower end, and the upper end is spaced apart from the inner surfaces of the first cutting groove 31 and the bending groove 33 by a predetermined distance and protrudes to the outside. It is provided with a cutting portion 43 connected to be inclined upwardly as possible,

When the cap is not coupled to the container, the shape-retaining member 40 is not separated from the cap body 20, and when the cap is coupled to the spout 11 of the container, the binding projection 12 is the shape-retaining member It is characterized in that the cutting part 43 is cut while pressing 40 to the outside, and the shape-retaining member 40 can be removed and removed through the gripping part 42.

Hereinafter, the shape-retaining member 40 will be described on behalf of the first cut-out groove 31.

The shape-retaining member 40 has a body portion 41 corresponding to the first cut-out groove 31, and a gripping portion 42 bent in a 'b' shape is provided at the bottom of the body portion 41. Part of the upper end of the body portion 41 is connected to the bottom surface of the upper surface portion 23, more precisely, the second cutting groove 32 in a thin thickness to form a cutting portion 43.

At this time, the torso portion 41 is provided with a filling protrusion (41a) that protrudes in the same shape as the locking protrusion 22 corresponding to the first cutting groove (31) to fill the fractured portion of the locking protrusion (22), The cutting portion 43 is connected to the upper surface portion 23 in a diagonal direction in a form spaced apart from the inner surface of the first cutting groove 31 toward the upper side of (41a).

That is, the upper end of the trunk portion 41 except for the filling protrusion 41a is opened so as not to contact the inner surface of the first cutting groove 31, so that the inner surface of the first cutting groove 31 and the cutting portion 43 They are spaced apart from each other in an inverted triangle shape.

If such a shape-retaining member 40 is fitted in the first cut-out groove 31 of the cap body 20, the shape-retaining member 40 is first cut when the cap is press-fitted into the spout 11 of the container. The groove 31, in particular, supports the part where the locking projection 22 is cut off, thereby preventing the opening of the first cutting groove 31 from being crushed.

In addition, when the coupling of the cap is completed, the binding projection 12 of the container is engaged with the upper portion of the locking projection 22, at this time, due to the protruding structure of the binding projection 12, the cutting portion 43 is outside, the first cutting groove Pressed in the direction of (31), the cutting portion 43 is cut off from the upper surface portion 23, the shape-retaining member 40 is separated from the cap body 20.

In this state, by holding the gripping portion 42 and grabbing the shape retaining member 40 through the lower opening of the first cutting groove 31 and removing it, the shape of the first cutting groove 31 and the locking protrusion 22 is completely removed. It can be used in a retained state, so that the cap can be easily removed later.

In the above description of the present invention, the container cap has been mainly described with reference to the accompanying drawings, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications, changes and substitutions are within the protection scope of the present invention. It should be interpreted as belonging.
