Description

Container Cap {CLOSURE OF VESSEL}

The present invention relates to a container closure wherein the first content is stored in the container and the second content is stored in the container closure to mix the second content with the first content before the container closure is separated from the container.

Generally, containers containing beverages, cosmetics, or medicines are made up of a container having a space for accommodating the contents of the container, and a container cap for hermetically sealing the inlet of the container. .

Recently, with the emergence of functional beverages, cosmetics or drugs using two or more materials, there is a need for a container having a structure capable of mixing different contents at the time of use by a consumer.

In one example, most beverages are premixed and distributed, for example vitamins such as vitamin C are not only destroyed relatively quickly by heat or ultraviolet light or by bonding with water or water, but also have a reduced content.

Therefore, it is preferable to add the sensitive vitamin just before consuming the beverage. For the same reason, transparent, translucent or well-permeable containers are often not suitable for long-term storage of vitamin beverages.

Accordingly, a beverage container has been developed that is easy to handle and allows the consumer to easily add the sensitive active second content immediately before consumption of the base beverage.

The container stopper rotates the actuating member while the actuating member is lowered, and the rupture knife separates the rupture film to introduce the second contents stored in the actuating member into the container.

However, the conventional container cap as described above is not only hard to separate the rupture film, but also does not have a structure that can prevent the reverse rotation of the operating member, so that when the operating member is rotated in the reverse direction, the second contents are poured out of the plug. There is a problem that may cause a malfunction.

In addition, the conventional container stopper is formed in the rupture knife is inclined on the lower surface of the operating member to cut the tear film, at this time, because the position of the rupture film cut by the rupture knife in accordance with the assembly position of the operating member is changed to the rupture film fixed member There is a problem that can be separated from.

In addition, the conventional container cap stops the operation member when the operation member is held by the hand to rotate, at this time, because the outer diameter of the operation member is small, difficult to hold and turn by the hand, it is inconvenient to use because you need to hold and turn the operating member to descend There is.

A second female screw portion 64 is formed to be screwed to the male screw portion 16.

A space is formed between the first coupling portion 22 and the second coupling portion 24 at the lower side thereof, and the container inlet 14 is inserted into the space.

On the outer surface of the second coupling portion 24 is formed a non-slip projection 66 for preventing the slip when the container stopper by hand to turn the container plug to remove from the container inlet (14).

In addition, a skirt 68 is formed at the lower end of the second coupling part 24 to be fixed to the outer circumferential surface of the container inlet 14. Here, the skirt 68 serves to maintain the container stopper coupled to the container inlet 14, and when the container stopper is detached from the container inlet 14, the skirt 68 is torn off for the first time. Confirm that it is done.

The storage cap 30 is in a state where the upper side is blocked, and the lower side is formed in an open form, and the second contents 32 are stored therein.

The outer surface of the storage cap 30 is formed with a male threaded portion 60 which is screwed with the first female threaded portion 62, and one side of the outer circumferential surface is formed so that the sealing ring 142 is protruded to be in close contact with the inner surface of the stopper body 20. do.

That is, between the storage cap 30 and the stopper body 20 is in close contact between the lower outer surface of the storage cap 30 and the lower inner surface of the stopper body 20 to perform a primary sealing action, and the sealing ring 142 is two. By sealing the car, the second contents 32 stored in the storage cap 30 are completely prevented from leaking out, and external contaminants are prevented from entering the storage cap 30.

Then, the lower portion of the storage cap 30 is formed with a push portion 34 for cutting the opening member (40). Here, the push part 34 is formed in a horizontal circular ring shape. That is, the push part 34 is formed without parallel to any part of the push surface as a whole.

Here, the push part 34 may be formed in a sharper shape toward the lower side so as to easily cut the opening member 40.

The rotating member 50 is rotatably supported by the lower inner surface on the upper outer circumferential surface of the stopper body 20, the upper side is bent inward so that the end is disposed on the outer circumferential surface of the storage cap 30. And, on the outer circumferential surface of the rotating member 50 is formed a non-slip projection 52 which is easy to turn and hold the rotating member 50 by hand.

A ring groove 54 is formed in the lower inner surface of the rotary member 50 in the circumferential direction, and a ring protrusion 56 is inserted into the ring groove 54 on the upper outer surface of the stopper body 20. Therefore, the rotating member 50 is rotatably supported by the stopper body 20.

When the rotating member 50 is rotated between the rotating member 50 and the outer circumferential surface of the storage cap 30, a rotation force transmitting unit 70 is formed to rotate the storage cap 30 together.

Rotation force transmitting unit 70 is an elastic protrusion 72 formed on the inner surface of the rotating member 50 at intervals in the circumferential direction, and protrudes at a predetermined interval in the circumferential direction on the outer peripheral surface of the storage cap 30 elastic protrusion ( And a locking protrusion 74 that is engaged with 72.

The rotational force transmitting unit 70 is rotated in one direction when the rotating member 50 is rotated by the rotational force of the rotating member 50 is transferred to the storage cap 30, rotates the rotating member 50 in the reverse direction the rotating member It has a reverse rotation prevention structure to prevent the rotational force of the 50 is transmitted to the storage cap 30.

The elastic protrusion 72 is formed at a predetermined interval in the circumferential direction on the upper inner surface of the rotating member 50, one surface thereof is formed with an acute angle 84 having an acute angle (θ1) with the inner surface of the rotating member 50 , The other surface is formed of an obtuse surface 86 having an obtuse angle θ2 with the inner surface of the rotating member 50. Therefore, the elastic protrusion 72 is formed to be inclined in one direction along the circumferential direction of the rotating member 50.

The locking protrusion 74 has one surface in contact with the acute angle surface 84 of the elastic protrusion 72 as a straight surface 82, and the other surface in contact with the obtuse surface 86 of the elastic protrusion 72 is inclined surface 80. Is formed.

When the rotational force transmitting unit rotates the rotation member 50 in the forward direction, the acute angle 84 of the elastic protrusion 72 and the straight surface 82 of the locking protrusion 74 are in contact with each other, so that the rotational force of the rotation member 50 is increased. The storage cap 30 is delivered to the storage cap 30 is rotated together.

When the rotating member 50 is rotated in the reverse direction, the obtuse surface 86 of the elastic protrusion 72 and the inclined surface 80 of the locking protrusion 74 are in contact with each other, and the obtuse surface 86 of the elastic protrusion 72 is contacted with each other. As it is bent over the inclined surface 80 of the locking projection 74, the rotational force of the rotating member 50 is not transmitted to the storage cap 30 to prevent the reverse rotation of the storage cap 30.

The locking protrusion 74 is formed in the vertical direction as long as the length (H) when the rotating member 50 is rotated because the storage cap 30 is screwed to the stopper body 20 when the storage cap 30 is lowered The elastic protrusion 72 is linearly moved along the locking protrusion 74.

The rotating member 50 and the storage cap 30 are manufactured by one mold work as one part in a mold. That is, the outer circumferential surface of the rotating member 50 and the inner circumferential surface of the storage cap 30 are connected by the connection part 100 to form the rotating member 50 and the storage cap 30 integrally.

Here, the connection portion 100 has a thin film form that separates between the rotating member 50 and the storage cap 30 while being torn when applying a predetermined force. As such, since the rotating member 50 and the storage cap 30 are integrally molded by a mold, productivity can be improved.

Specifically, the connection part 100 is formed between the end of the locking protrusion 74 and the inner surface of the rotating member 50. Therefore, when the rotating cap 50 is rotated in a state in which the storage cap 30 is screwed to the stopper body 20, the storage cap 30 is lowered, and thus the connection part 100 is torn off and thus the rotating member 50. And the storage cap 30 is separated.

Looking at the structure in which the rotating member 50 and the storage cap 30 is formed integrally, the elastic projection 72 is located in the middle between the two locking projections 74, the end of the locking projection 74 and the rotating member ( The connection part 100 is formed between the inner surfaces of the 50.

The connecting portion 110 according to another embodiment may be formed between the end of the elastic protrusion 72 and the outer circumferential surface of the storage cap 30, as shown in Figure 6, as shown in Figure 7, The connection part 120 may be formed between the inner circumferential surface of the rotating member 50 and the inner circumferential surface of the storage cap 30.

Then, the unsealing member 40 is integrally molded at the lower end of the stopper body 20. That is, when shaping the stopper body 20 into a mold, the opening member 40 is also molded. Of course, the opening member 40 is manufactured separately from the closure body and can also be applied to a method of bonding to the closure body using heat fusion or adhesive.

As shown in FIG. 8, the bottom surface of the stopper body 20 is formed in an inclined surface shape in which one side extends downward. Therefore, the unsealing member 40 formed on the stopper body 20 is formed to be inclined by the angle θ. Here, the unsealing member 40 becomes a cutting part 46 which starts to be torn off by the push part 34 in a part arranged on the upper side, and the part arranged on the lower side is rotated without being torn by the stopper body 20. It becomes the hinge part 48 which becomes.

Here, the hinge portion 48 is preferably formed small so that only the rotation in the state attached to the stopper body 20. The remaining portion except for the hinge portion 48 becomes the cut portion 46.

The cutting portion 46 is formed with a cutting groove 42 to be easily torn off by the pushing force of the push portion 34, the hinge portion 48 to the hinge to facilitate the opening member 40 to rotate in the downward direction. Grooves 44 are formed.

Here, the cutting groove 42 forms a deep depth to make the thickness T1 of the cutting portion 46 thin, and the hinge groove 44 does not have a depth deeper than that of the cutting groove 42, thereby the hinge portion 48. Thicken the thickness (T2) so that it does not tear but only rotates.

Cutting groove 42 and the hinge groove 44 is a structure formed on the lower surface of the opening member 40, in addition to this structure, as shown in Figure 9, the cutting groove 90 on the upper side of the opening member 40. And the hinge groove 92 is formed is also applicable to the structure, as shown in Figure 10, the cutting groove 94 is formed in the corner portion of the portion where the opening member 40 and the stopper body 20 are interconnected. ) And the hinge groove 96 structure is also applicable.

In this case, the cut portion formed by the cutting grooves 90 and 94 is formed to have a thin thickness, and the hinge portion formed by the hinge grooves 92 and 96 is formed to have a thick thickness.

Looking at the action of the opening member 40, when the storage cap 30 is lowered by the rotation, the push portion 34 is in contact with the cutting portion 46 disposed on the uppermost portion of the opening member (40). Therefore, the downward force of the push part 34 is concentrated on the uppermost part of the unsealing member 40, so that the unsealing member 40 can be easily separated.

At this time, since the push portion 34 is formed in a horizontal circular ring shape, any one portion of the push portion 34 may contact the cut portion 46 of the opening member 40, and thus, the storage cap 30 and the stopper body. There is no need to precisely set the assembly position between the (20) can be easily assembled.

In addition, since the opening member 40 is formed to be inclined, when the push part 34 is further lowered, the tearing of the cutting part 46 is expanded along the inclined surface of the opening member 40, and the tearing of the cutting part 46 is completed. When the opening member 40 is rotated about the hinge portion 48 by the pushing force of the push portion 34 to maintain the state attached to the stopper body 20.

And, as shown in Figure 11, the push portion 34 formed on the lower surface of the storage cap 30 is formed in the inclined surface inclined by the inclination angle (θ), the opening member 40 is formed in a horizontal plane The structure is also applicable.

As such, the operation of the container closure according to one embodiment is described below.

12 and 13 are operational state diagrams of the container closure according to an embodiment of the present invention.

First, the assembly process between the storage cap 30 and the stopper body 20 will be described.

The storage cap 30 and the rotating member 50 are connected to the connection portion 100 is formed integrally by the mold.

After arranging the storage cap 30 and the rotating member 50 so that the inlet faces upward, the second cap 32 is filled in the storage cap 30, and the stopper body 20 is upper side of the storage cap 30. Assemble downwards from.

Then, the ring groove 54 of the rotating member 50 is fitted to the ring projection 56 of the stopper body 20 to be rotatably supported, and stored in the first female threaded portion 62 of the stopper body 20. The male thread portion 60 of the cap 30 is screwed. In this state, when the rotating member 50 is rotated, the storage cap 30 is lowered, and at this time, the connecting part 100 connected between the rotating member 50 and the storage cap 30 is torn off and stored with the rotating member 50. The cap 30 is separated between them.

Further, when the rotation member 50 is further rotated, the storage cap 30 is further lowered so that the male threaded portion 60 of the storage cap 30 is completely screwed to the first female threaded portion 62 of the stopper body 20. The sealing ring 70 of the storage cap 30 is in close contact with the inner surface of the stopper body 20 to maintain airtightness so that the second contents stored in the storage cap 30 do not spill out.

As such, when the storage cap 30 is completed when the stopper body 20 is assembled, the connection part 100 connected between the rotating member 50 and the storage cap 30 is torn and the storage cap 30 and the stopper body ( 20) are separated.

And, in addition to such a structure, when the storage cap 30 is completely assembled to the stopper body 20, a structure in which the connecting portion 100 is maintained between the rotating member 50 and the storage cap 30 is also applicable. In this case, when the opening member 40 is separated to mix the first contents 12 and the second contents 32, the connecting portion 100 is torn.

As such, when the assembly of the container stopper is completed, the container stopper is coupled to the container inlet 14 of the container 10 in which the first contents 12 are stored.

In the following, the operation of the container closure will be described in detail.

When the rotating member 50 is rotated, the rotational force of the rotating member 50 is transmitted to the storage cap 30 by the rotational force transmitting unit 70 formed between the rotating member 50 and the storage cap 30 to store the storage cap 30. ) Is rotated. Then, the storage cap 30 is screwed with the stopper body 20 so that the storage cap 30 is lowered and separates a part of the opening member 40 from the stopper body 20.

That is, when the rotating member 50 is rotated in the forward direction, the acute angle 82 of the elastic protrusion 72 formed on the rotating member 50 and the straight surface 82 of the locking protrusion 74 formed on the storage cap 30 are In contact with each other the rotational force of the rotating member 50 is transmitted to the storage cap (30).

When the rotating member 50 is rotated in a reverse direction due to carelessness of a user, the obtuse angle surface 86 of the elastic protrusion 72 and the inclined surface 80 of the locking protrusion 74 formed on the stopper body 20 come into contact with each other. And the elastic protrusion 72 is bent to rotate the rotation member 50 is idling and thus the rotational force of the rotation member 50 is not transmitted to the storage cap 30 to prevent malfunction of the storage cap.

Therefore, the storage cap 30 can be prevented from being separated from the plug body 20 by a malfunction, thereby preventing the second contents 32 stored in the storage cap 30 from pouring out.

When the storage cap 30 is lowered, the push portion 34 is in contact with the upper cut portion 46 of the opening member 40. At this time, since the opening member 40 is formed to be inclined, the push part 34 first contacts the upper cut part 46 of the opening member 40 so that the force of the push part 34 is concentrated on one part of the opening member 40. Therefore, the opening member 40 may be more easily cut. In addition, since the cut portion 46 is formed in a thin film form, it may be easily torn off by the pushing force of the push portion 34.

And, since the push portion 34 is formed in a horizontal plane shape, when the storage cap 30 is lowered, any portion of the push portion 34 contacts the cut portion 46 of the opening member 40, so that the storage cap ( 30) when assembling the stopper body 20 does not need to align the position is convenient assembly.

As such, when the storage cap 30 is rotated and lowered gradually, the cutting portion 46 of the opening member 40 is gradually cut and the opening member 40 is rotated about the hinge portion 48 and the storage cap 30 is rotated. The second content 32 stored in) is introduced into the container and mixed with the first content 12.

At this time, since the hinge portion 48 is formed to have a thick thickness and is disposed at the lowermost side, the hinge portion 48 maintains a state of being attached to the stopper body 20 without being cut. Accordingly, the opening member 40 may be separated from the plug body 20 to prevent the opening member 40 from entering the container 10.

And, when the storage cap 30 is lowered to the maximum, as shown in Figure 12, the elastic projection 72 is disposed in the position away from the top of the locking projection 74, even if the rotating member 50 continues to rotate Since the rotational force of the rotating member 50 is not transmitted to the storage cap 30, the storage cap 30 may be prevented from falling over a set distance. Here, the length (H) of the locking protrusion 74 is adjusted in proportion to the descending distance of the storage cap (30).

When the input of the second contents 32 is completed in this manner, as shown in FIG. 13, the stopper body 20 is rotated to be separated from the container inlet 14, and then the first through the container inlet 14. The contents of the contents 12 and the second contents 32 are discharged to the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.
