Description

PUSHING CAP AND THE BOTTLE HAVING THE SAME

The present invention relates to a cap and a container having the cap, particularly a pushing cap for discharging a gas and a container having the pushing cap, for traditional liquid, such as Makkolli.

Raw Makkolli that is Korean traditional fermented food continuously produces a fermented gas during the distribution process for transporting it to customers after being made, such that when it is packed in a plastic container, the internal pressure of the container is increased by the fermented gas and expansion pressure is uniformly generated in the container. Therefore, when the inlet of the container is completely sealed by a cap and packing, the internal pressure continuously increases, such that the container may deform or the cap may break.

On the contrary, when sealing is incomplete, the substance in the container leaks and contaminates the periphery when the container is inclined, or a large amount of fermented gas leaks, such that the unique scent and taste of Makkolli are lost.

Further, for the characteristics of the contents of Makkolli of which the contents are not finely filtered, dregs are produced during the distribution, and in general, customers shake the Makkolli container to mix the dregs before drinking. In this shaking, fermented gas bubbles dissolved in the substance in the Makkolli container are generated, and then, when the cap is opened, the substance and the fermented gas are mixed and overflow in a foam state due to a pressure difference from the atmospheric pressure.

As a result, in order to pack fermented food, such as raw Makkolli, it is required to design a package with low cost and high efficiency for keeping the taste and scent of food by keeping a predetermined amount of fermented gas in a container filled with fermented food, for discharging a predetermined amount of fermented gas to the outside to prevent the container or the cap from being broken by excessive increase of internal pressure, and for minimizing the packing cost.

The present invention has been made in an effort to provide a pushing cap that prevents the substance in a container from bubbling and overflowing due to a pressure difference between an internal fermented gas and the atmosphere when drinking the substance by opening the container for fermented traditional liquor, and maintains equilibrium with the atmospheric pressure by discharging a predetermined amount of fermented gas in the container before the container is opened.

An embodiment of the present invention provides a cap for a container which seals the container by being combined with the container, and the cap includes a cap body, a press-contact surface, a press plate, and a packing. The cap body is thread-fastened to the container. The press-contact surface is formed at the upper end of the cap body and is in press contact with the inlet of the container when the container and the cap body are combined. The press plate is disposed at the center of the press-contact surface, has a boring protrusion on the bottom, and is pressed down with predetermined elasticity into a lid. The packing is disposed between the cap body and the inlet of the container.

Further, a protrusion that protrudes higher than the press plate may be further formed around the press-contact surface.

Further, the packing may further have a vibration plate that has a cutting line and produces vibration sound in accordance with discharge of a gas in the container, when being pressed by the boring protrusion.

Further, discontinuous threads may be formed on the inner circumferential surface of the cap body to be thread-fastened to the container.

Further, the packing may further include a synthetic resin film that forms a gap between the press-contact surface and the inlet of the container due to wrinkling, when being bored by press of the boring protrusion.

Further, the boring protrusion may have a through-hole at the axial center.

Meanwhile, a container for keeping traditional fermented liquor according to the present invention includes the following cap and container body. The cap includes: a cap body that is thread-fastened to the container; a press-contact surface that is formed at the upper end of the cap body and is in press contact with an inlet of the container when the container and the cap body are coupled; a press plate that is disposed at the center of the press-contact surface, has a boring protrusion on the bottom, and is pressed down with predetermined elasticity into a lid; and a packing that is disposed between the cap body and the inlet of the container. A container body has an inlet thread-fastened to the cap body and a cap coupling portion with a groove having a predetermined length at the axial center on the outer circumferential surface of the inlet.

Further, the boring protrusion may have a through-hole at the axial center.

According to a pushing cap and a container for traditional fermented liquor having the pushing cap of the present invention, solubility of a fermented gas is increased by press of a press plate, such that it is possible to reduce overflow of a substance in the container when the container is opened.

Further, according to the present invention, it is possible to discharge a predetermined amount of fermented gas in a container into a cap by using a boring protrusion, and keep equilibrium between atmospheric pressure and pressure of a fermented gas in a container by forming a separate channel for discharging the fermented gas.

As a result, even without specific filling/capping equipment, it is possible to make traditional fermented liquor, such as Makkolli, by using common existing Makkolli filling/capping equipment. Further, since it is possible to insert a packing that is manufactured in advance in the same manufacturing method as a common Makkolli cap, such that it is possible to manufacture a cap by using the existing Makkolli cap manufacturing equipment, even without specific equipment.

Further, since a gas is made produce specific sound by vibrating a vibration plate, a user can recognize with ears that a gas is discharged.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. The terms representing directions, such as “up, down, left, and right” used herein are considered to be based on the status shown in the drawings, if not specifically defined or stated.

[Embodiment 1]

The embodiment is characterized by a container cap 100 that is combined with a container for sealing. The container cap 100 according to the embodiment is composed of a cap body 110, a press-contact surface 120, a press plate 121, an elastic member, and a packing 200, as shown in FIG. 3. The components are described hereafter in detail.

The cap body 110 makes the body of the container cap 100 and is made of synthetic resin in a cylindrical shape. Threads are formed on the inner circumferential surface of the cap body 110, for thread-fastening with the container, which is described below.

The press-contact surface 120 that partially extends from the top of the cap body 110 toward the axial center is formed at the top of the cap body 110. The press-contact surface 120 comes in press-contact with the inlet of a container 300 (see FIG. 7), when the container 300 and the cap body 110 are thread-fastened. The press-contact surface 120 has predetermined strength and limits depth of the inlet of the container 300 which is inserted in the cap body 110.

The press plate 121 is disposed at the center of the press-contact surface 120. The press plate 121 is connected with the press-contact surface 120 by an elastic member 122 having predetermined elasticity. When the press plate 121 is pressed down by an external force, as shown in FIG. 2, the elastic member 122 deforms and the press plate 121 moves down. In this state, it is possible to restore the press plate 121 pressed down or keep the press plate pressed down, by controlling reacting force of the elastic member 122. Meanwhile, it is preferable to improve sealing performance by integrally forming the press plate 121, elastic member 122, and press-contact surface 120, with different thicknesses.

A boring protrusion 123 is formed on the bottom of the pressing plate 121. The boring protrusion 123 protrudes downward from the bottom of the press plate 121, such that it bores the packing 200, when the press plate 121 is pressed down, as shown in FIG. 5.

A protrusion 114 protrudes upward from the upper end of the cap body 110. The protrusion 114 has a height larger than the height when the press plate 121 is at the highest. The protrusion 114 has a function that prevents the press plate from being easily pressed down even during distribution of a container according to the embodiment.

The packing 200 is positioned between the press-contact surface 120 and the end of the inlet 301 of the container, when the inlet 301 of the container is inserted and coupled in the cap body 110. The packing 200 keeps the inside of the container sealed for a long time by being in press contact by the inlet 301 of the container.

Meanwhile, the packing 200 may be formed in a multilayer in accordance with the desired usage, as shown in FIG. 4. For example, the packing 200 may be formed of a non-woven fabric layer or a plurality of synthetic resin layers.

That is, a non-woven fabric layer 201, which improves sealing performance of the inlet 301 of the container by partially contracting between the press-contact surface 120 and the upper end of the inlet 301 of the container, when the cap body 110 and the inlet 301 of the container are coupled, may be formed. The non-woven fabric layer 201 may be made of PET (Polyester), PP (Polypropylene), or PE (Polyethylene).

Further, a first synthetic resin layer 202 may be provided. The first synthetic resin layer 202 has a through hole having a predetermined size at the center and keeps the shape of the packing 200 while not interfering with boring of the boring protrusion 123 and having predetermined strength or more.

Further, a second synthetic resin layer 203 and a third synthetic resin layer 204 may be provided. Half-cutting lines are formed on the second synthetic resin layer 203 ad the third synthetic resin layer 204, not overlapping each other. The half-cutting lines are formed with thicknesses smaller than the other portions of the synthetic resins such that desired portions can be easily bored by the boring protrusion 123. Meanwhile, the half-cutting lines may be unexpectedly cut during distribution. In this case, since two films are in contact by pressure of the substance in the container even if the container is inclined, the cutting lines are blocked by other synthetic resin layer, such that the substance does not leak or the gas is not discharged at one time.

Any one may be used for the first synthetic resin 202, the second synthetic resin 203, and the third synthetic resin 204 with predetermined types and thicknesses, as long as it has appropriate strength and elasticity, various laminate films, such as PE (Polyethylene) film, PP (Polypropylene) film, or PP/PE, PP/PE/PP, and PET/CPP.

Meanwhile, the layers of the packing 200 may be used as the packing 200 after being bonded by thermal bonding, and as shown in FIG. 3, a packing-locking protrusion 111 may be formed such that the packing 200 is not separated.

Meanwhile, a vibration plate that produces vibration sound in accordance with discharge of the gas in the container when pressed by the boring protrusion 123 presses may be formed on one layer of the packing 200. The vibration plate may be implemented by forming two parallel half-cutting lines with a small width on a synthetic resin.

Further, a wrinkling layer 205 may be further provided. The wrinkling layer 205 are formed to have higher strength against press of the boring protrusion 123 than the layers of other packings 200, or in order not to form a half-cutting line. The wrinkling layer 205 generates wrinkling in boring, by being further pushed by the boring protrusion 123 until it is bored, as compared with other layers. When wrinkling is generated, a fine gap through which the gas in the container body 300 is discharged is formed by forming a gap between the press-contact surface 120 and the upper end of the inlet 301 of the container.

[Embodiment 2]

Embodiment 2 is characterized in that a channel for discharging a gas is formed between a cap body 110 and the outer circumferential surface of an inlet 301 (see FIG. 7) of a container, as shown in FIG. 6.

Threads 112 are discontinuously formed on the inner circumferential surface of the cap body 100 such that gas discharge channels 113 are formed between the threads.

The gas discharge channels may be formed at the container body 300. That is, second gas channels 311 may be formed by discontinuous forming the threads 310 formed on the inlet 301 of the container 300, or it is possible to ensure channels for discharging the gas by forming groove having predetermined lengths at the inlet 301 of the container, along the second discharge channels 311.

Channels for discharging the gas can be ensured between the inner circumferential surface of the cap 100 and the outer circumferential surface of the inlet 301 of the container, even if the cap 100 and the container body 300 are combined, through the

gas discharge channels

112 and 311.

[Embodiment 3]

Embodiment 3 relates to when a fine through-hole 124 is formed to easily discharge a gas, as shown in FIG. 8. The fine through-hole 124 is formed through the axial center of the boring protrusion 124. As shown in FIG. 8, after a press plate 121 is pressed down and a packing 200 is bored, the fermented gas in the container body 300 is discharged outside through the fine through-hole 124. In this configuration, since the diameter of the fine through-hole 124 is not large, the gas is slowly discharged and the substance in the container body 300 does not rapidly bubble and overflow.

Although preferred embodiments of the present invention were described above, the scope of the present invention is not limited to the preferred embodiments and can be implemented by a cap with a variety of press plates and a container for traditional fermented liquor, without departing from the scope of the present invention described in claims.
