Description

Valve for fermented product packaging container and lid assembly for fermented product packaging container including the same {valve for fermented product packaging container and lid assembly of fermented product packaging container including the same}

The present invention relates to a valve for a fermented product packaging container that is installed in a container containing a fermented product and can discharge gas generated from the fermented product to the outside of the container, and a lid assembly for a fermented product packaging container including the same.

In general, fermented products such as makgeolli and kimchi are distributed in plastic containers, and fermentation gas is generated within the container as fermentation continues even when the container is fully packaged.

If these fermentation gases cannot be released to the outside, the shape of the container may be deformed and the taste of makgeolli or fermented products may change, so the stopper or lid used in the makgeolli or fermented product container must have an outlet through which the fermentation gas is discharged.

Therefore, among the conventional makgeolli bottle caps, for example, a bottle cap made of aluminum was used by interpolating a non-woven fabric that allows air to escape but prevents liquid, such as the contents, from escaping. However, in this case, the locking state of the bottle neck and the bottle cap was excessive, and if the top of the bottle neck pressed strongly against the non-woven fabric, there was a problem in that the original non-woven fabric could not function.

In addition, since this conventional bottle cap structure does not provide a structure that allows general consumers to artificially discharge only fermentation gas, the present applicant proposes a structure that allows general consumers to easily discharge only fermentation gas. .

Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below and will be implemented in various different forms. These embodiments only serve to ensure that the disclosure of the present invention is complete and to those skilled in the art to fully convey the scope of the invention. This is provided to inform you. In the drawings, like symbols refer to like elements.

The valve for the fermented product packaging container according to a preferred embodiment of the present invention and the lid assembly of the fermented product packaging container including the same are installed in the container containing the fermented product to discharge the fermentation gas generated from the fermented product to the outside of the container. , the scope of application has been expanded so that not only food manufacturers can apply it, but also general consumers can easily apply it.

Hereinafter, the present invention will be described in detail with reference to examples.

As shown in Figures 1 to 3, the lid assembly 100 of the fermented product packaging container according to an embodiment of the present invention includes the lid 110 of the fermented product packaging container in which the gas discharge hole 111 is formed and the gas discharge hole. It includes a valve 300 for a fermented product packaging container that is forcibly press-fitted and fixed to (111).

Here, the gas discharge hole 111 may be formed in the lid 110 during the production process of a food manufacturer that manufactures fermented products such as raw makgeolli and kimchi, and unlike this, general consumers may use the gas discharge hole 111. You can also purchase regular raw makgeolli products that have not been formed and then form them using a sharp tool. In the latter case, even general consumers can easily apply the valve 300 for packaging containers of the present invention to existing fermented products.

In addition, if the packaging container 10 is a general food packaging container rather than a fermented food packaging container, the user artificially forms a gas discharge hole in the lid 110 using a tool, and then uses the gas discharge hole for packaging the fermented product. By inserting the service valve 300, a general food packaging container can be repurposed and used as a fermented food packaging container for storing fermented food.

Specifically, it can be easily applied through a simple operation of forming a gas discharge hole 111 in the lid of a general fermented product, for example, a raw makgeolli packaging container, using an awl, etc., and then forcing the valve 300, which will be described later, by force. there is.

In an embodiment of the present invention, the valve 300 (hereinafter referred to as 'valve') for a fermented product packaging container is coupled to the lid 110 of the fermented product packaging container and includes a main body 310 and a filter 380.

As shown in Figures 2 and 3, the main body 310 is forcibly press-fitted and fixed to the gas discharge hole 111 formed in the lid 110, and is provided on the inside to communicate the internal space and external space of the packaging container 10. A communication hole 311 is provided to allow this.

The filter 380 is coupled to the main body 310 in a form that closes the communication hole 311 so that only the fermentation gas generated in the packaging container is discharged to the outside through the communication hole 311. That is, the filter 380 is configured to be filterable so that only the fermentation gas is discharged to the outside and the liquid fermentation product is not discharged to the outside.

In an embodiment of the present invention, the filter 380 has a plurality of fine pores and can be applied as a nano-membrane filter to allow gas to pass through but not liquid to pass through.

Here, the filter 380 is formed in the form of a plate with a thickness of a certain level or more, and can be coupled to the main body 310 in various forms as shown in FIG. 2.

As an example, the filter 380 may be forcibly pressed into the communication hole 311 and placed in a state of contact and support on the inner peripheral surface of the communication hole. To this end, the user may use a long tool to move the filter to an appropriate position inside the communication hole. (380) can be forcefully inserted. Additionally, as a modified example, which will be described later, the filter may be provided with its edge area disposed inside the filter fixing groove.

In an embodiment of the present invention, while the main body 310 is forcibly pressed into the gas discharge hole 111 of the lid 110, the contents (liquid) of the fermented product are not discharged to the outside through the gas discharge hole 111. It is desirable that the main body 310 is in close contact with the inner peripheral surface of the gas discharge hole 111 without any gaps.

To this end, the main body 310 may include at least one material selected from the group consisting of elastically compressible and expandable rubber, silicone, and sponge.

As shown in Figures 2 and 3, the main body 310 includes an upper main body 320, a central main body 330, and a lower main body 340.

The upper body 320 can be placed outside the lid 110, and the central body 330 is integrally connected to the upper body 320 and can be placed inside the gas discharge hole 111 of the lid 110, The lower body 340 is integrally connected to the central body 330 and can be placed inside the lid 110.

The lower body 340 is made to have a cross-sectional area larger than the diameter of the gas discharge hole 111, and is rapidly compressed when inserted into the gas discharge hole 111, and then returns to its initial size after passing through the gas discharge hole 111. It expands and can be caught on the inner surface of the lid 110. Here, the lower body 340 is in close contact with the inner surface of the lid (the surface facing the inner space of the container) after expansion to prevent the liquid contents from leaking. Likewise, the central body 330 is also in close contact with the inner circumferential surface of the gas discharge hole 111 so that no gaps are created, thereby preventing leakage of liquid contents.

In an embodiment of the present invention, the main body 310 may be provided with a filter fixing groove 350 that is connected to the communication hole 311 and has a larger cross-sectional area than the communication hole 311. In this case, the filter 380 may close the communication hole 311 with its edge disposed inside the filter fixing groove 350.

In addition, the edge of the filter 380 is in close contact with the circumferential surface of the filter fixing groove 350 to prevent liquid contents from being discharged to the outside through the gap between the filter and the circumferential surface of the filter fixing groove.

The filter 380 is formed in a plate shape with a larger cross-sectional area than the communication hole 311, and can be prevented from being separated from the filter fixing groove 350 by being caught on the inner wall forming the filter fixing groove 350.

In an embodiment of the present invention, the upper surface of the edge area of the filter 380 is in close contact with the upper inner surface of the filter fixing groove 350 based on FIGS. 2 and 3 to stably prevent leakage of liquid contents in the fermented product packaging container. It is preferable that the lower surface of the edge area of the filter 380 is in close contact with the lower inner surface of the filter fixing groove 350, and the side surface of the edge area of the filter 380 is in close contact with the inner peripheral surface of the filter fixing groove 350. desirable.

On the other hand, when a coupling error occurs between the filter fixing groove 350 formed on the main body 310 and the filter 380, that is, as described above, the upper, lower, and side surfaces of the edge area of the filter correspond to the filter fixing groove. If it is not in close contact with the surface, the filter 380 placed in the filter fixing groove 350 may slightly move in the up and down direction based on the drawing.

The present invention proposes an additional structure that limits the slight upward and downward movement of the filter so that the filter 380 remains fixed and coupled to the main body 310 at all times.

Specifically, as shown in FIG. 4, the filter fixing groove 350 is provided in the communication hole 311 near the filter fixing groove 350 to attach the filter 380 to the inner wall (specifically In this way, a filter shaking prevention part 360 is further provided, which is fixed by pressing to the upper inner surface or lower inner surface of the filter fixing groove.

The filter shake prevention unit 360 includes a disk disk 362 with a hole 361 formed in the center, and a flap 363 that is inclinedly connected to the outer peripheral surface of the disk disk 362 in the vertical direction.

Here, as shown in FIG. 4, the upper end of the flap 363 of the filter shake prevention unit 360 is supported in contact with the upper inner surface of the filter fixing groove 350, and the lower end of the flap 363 is in contact with the filter 380. By contacting the upper surface, the filter 380 can be pressed downward, and as a result, the filter 380 is stably adhered to the lower inner surface of the filter fixing groove 350 while shaking is suppressed, thereby stably preventing the outflow of liquid contents. It can be prevented.

In an embodiment of the present invention, as shown in FIG. 5, the upper body 320 may be made of the first and second upper bodies 321 and 322 separated from each other joined to each other, and the first upper body ( A filter fixing groove 350 may be formed in 321).

The user (manufacturer) places the filter 380 or the filter 380 and the filter shaking prevention unit 360 in the filter fixing groove 350 of the first upper body 321 and then The filter 380 or the filter 380 and the filter shaking prevention unit 360 can be coupled to the main body 310 by bonding the second upper bodies 322 together. Here, the first upper body and the second upper body can be integrally joined to each other through fusion or the like.

In contrast, as shown in FIG. 6, the first upper body 321 and the second upper body 322 are positioned so that the corresponding surfaces of the first upper body 321 and the second upper body 322 facing each other are flat. ) without forming the filter fixing groove 350, the filter 380 is interposed between the first and second upper bodies 321 and 322 and the first and second upper bodies 321 and 322 are joined to form the filter 380. ) can also be fixed to the main body 310. In this case, the upper and lower edges of the filter 380 are in close contact with the opposing surfaces of the first upper body 321 and the second lower body 340, respectively, thereby preventing leakage of liquid contents.

Meanwhile, as described above, while the user forcibly presses the valve 300 into the gas discharge hole 111 of the lid 110, the body 310 made of an elastic material is rapidly compressed and opens the gas discharge hole 111. After passing through, it is preferable that the communication hole 311 maintains its set shape so that the fermentation gas expands to its initial state and is guided toward the filter 380 through the communication hole 311. However, in some cases, the main body 310 may be suddenly compressed into shape, which may cause the lower opening of the communication hole 311 to be closed by the lower main body 340.

To prevent such problems from occurring, as shown in FIG. 7, an insert is inserted into the communication hole 311 so as to contact the inner peripheral surface of the communication hole 311, and is made of a material having a certain rigidity greater than that of the main body 310. A pipe 370 is further provided.

The insertion pipe 370 has a tube shape with a length of a certain length or more and may be made of plastic or stainless steel-based material.

Here, the insertion pipe 370 is inserted so as to contact the inner peripheral surface of the communication hole 311 formed in the central body 330 and the lower body 340, even if rapid compression and shape deformation of the main body 310 occurs as described above. By supporting the inner peripheral surface of the communication hole 311, the communication hole 311 can be prevented from being closed.

Hereinafter, a valve for a fermented product packaging container according to another embodiment of the present invention and a lid assembly for a fermented product packaging container including the same will be described. Redundant description of the same configuration as the above-described embodiment will be omitted, and the same configuration will be described. The same reference numerals will be used.

In the lid assembly of the fermented product packaging container according to another embodiment of the present invention, the valve for the fermented product packaging container is different from the above-described embodiment, and the lid is applied in the same way, and the following description will focus on the valve for the fermented product packaging container. .

The valve for a fermented product packaging container according to another embodiment of the present invention has the function of discharging fermentation gas generated from the fermented product to the outside of the container while limiting the external discharge of the contents of the fermented product, and additionally prevents external air from flowing into the packaging container. This is to block it.

In addition, through a structure that blocks the inflow of external air into the fermented product contents, it prevents the fermented product contents from decaying or promoting decay due to contact between the fermented product contents and oxygen, and also allows the fermentation time to be relatively long. It has the advantage of being sustainable. This increase in fermentation time can improve characteristics such as taste and aroma of fermented products.

As shown in Figures 8 and 9, the valve 600 for a fermented product packaging container according to another embodiment of the present invention is coupled to the lid of the fermented product packaging container, and is connected to the main body 310, the filter 380, and the outside air. Includes an inflow prevention cap 610. Here, the main body 310 and filter 380 are the same as the above-described embodiment. However, the height of the filter fixing groove 350 of the main body 310 is formed to be larger than the filter thickness by a certain amount.

The external air inflow prevention cap 610 may be inserted and fixed into the communication hole 311 of the main body 310. For example, the outside air inflow prevention cap 610 can be fixed to the communication hole 311 by forcibly press-fitting it.

In another embodiment of the present invention, the outside air inflow prevention cap 610 allows the fermentation gas generated within the packaging container 10 to be discharged to the outside through the communication hole 311 and the filter 380, but prevents the outside air outside the packaging container from being discharged to the outside through the communication hole 311 and the filter 380. blocks the inflow into the fermented product packaging container through the communication hole 311.

To elaborate, the fermentation gas generated as fermentation of the contents proceeds in the packaging container 10 passes through the communication hole 311 and the inner hole of the outside air inflow prevention cap 610, and then through the outside air inflow prevention cap 610 and the main body ( 310) It can be discharged to the outside through the gap between them. At this time, the outside air is prevented from flowing back into the packaging container through the gap between the outside air inflow prevention cap 610 and the main body 310 due to the fermentation gas discharge pressure.

Here, the gap between the outside air inflow prevention cap 610 and the main body 310 is not always created, but is created instantaneously only by the discharge pressure of the fermentation gas, and when the fermentation gas is not discharged to the outside, the outside air inflow There is no gap between the edge of the prevention cap and the body. Accordingly, when the fermentation gas is not discharged to the outside, the outside air can be blocked by the outside air inflow prevention cap 610, thereby stably preventing the outside air from flowing into the communication hole 311.

As shown in Figures 8 and 9, in another embodiment of the present invention, the external air inflow prevention cap 610 is press-fitted and fixed to the communication hole 311 of the main body 310 and is installed inside the main body 310. An auxiliary communication hole 630 is provided to communicate with the external space and the communication hole 311.

Therefore, as shown in Figure 9, the fermentation gas in the fermented product packaging container sequentially passes through the communication hole 311, the filter 380, and the auxiliary communication hole 630, and then passes through the outside air inflow prevention cap 610 and the main body. (310) is finally discharged to the outside through the gap between them.

As in the above-described embodiment, the outside air inflow prevention cap 610 is made of an elastic material that is easy to elastically deform and restore, and includes an outside air inflow prevention upper body 611, outside air inflow prevention central body 612, and outside air inflow prevention lower body. Includes (613).

The external air inflow prevention upper body 611 can be placed on the outside of the main body 310, and its edge end is configured to elastically contact the upper surface of the main body 310.

Here, elastically contactable means that, as described above, when the fermentation gas is discharged to the outside, there is a gap between the outside air inflow prevention cap 610 and the main body 310, that is, the edge of the outside air inflow prevention upper body 611. The shape is elastically deformed so that a gap is created between the end and the upper surface of the main body 310, and when the fermentation gas is not discharged to the outside, the edge end of the upper body 611 and the main body 310 prevent outside air from entering. This means that the edge end of the external air inflow prevention upper body 611 is elastically restored to its shape so as to come into close contact with the upper surface of the main body 310 so that a gap is not created between the upper surfaces of the.

In this way, so that the outside air inflow prevention upper body 611 can easily elastically deform and restore its shape, as shown in Figures 8 and 9, the outside air inflow prevention upper body 611 has a cross section of a semicircle or ellipse with a concave inside. It can have a shape.

Next, the central body 612 to prevent outside air inflow is integrally connected to the upper body 611 to prevent outside air inflow and can be placed inserted into the communication hole 311. In addition, the outside air inflow prevention lower body 613 is integrally connected to the lower part of the outside air inflow prevention central body 612 and can be placed inside the filter fixing groove 350.

Here, the outer air inflow prevention lower body 613 is made to have a cross-sectional area larger than the communication hole 311 and is placed in a state where it can be caught on the inner surface of the filter fixing groove 350.

In addition, the outer air inflow prevention lower body 613 is rapidly compressed when inserted into the communication hole 311, and expands to its initial size after passing through the communication hole 311, thereby forming the inner upper surface of the filter fixing groove 350. It can become caught by contact with it. Likewise, the central body 612 to prevent external air inflow can be closely adhered to the inner peripheral surface of the communication hole 311 to prevent a gap from occurring between the central body 612 and the inner peripheral surface of the communication hole 311.

Meanwhile, the height of the filter fixing groove 350 is formed to be larger than the thickness of the filter 380, so that the filter can slightly move in the vertical direction. The lower body 613 to prevent external air inflow is in contact with the upper surface of the filter 380 to filter the filter. The movement of the filter can be prevented by pressing it to the lower bottom surface of the filter fixing groove 350 and fixing it in close contact.

In another embodiment of the present invention, the auxiliary communication hole 630 includes a first auxiliary communication hole 631 and a second auxiliary communication hole 632.

The first auxiliary communication hole 631 penetrates the outside air inflow prevention lower body 613 in the vertical direction and extends along the longitudinal direction of the outside air inflow prevention central body 612 for a certain length or more.

The second auxiliary communication hole 632 is composed of a plurality, and communicates in a radially branched state at the top of the first auxiliary communication hole 631, so that the inside of the first auxiliary communication hole 631 is connected to the upper surface of the main body 310. It communicates with the external space (the space between the inner space of the semicircular or oval-shaped upper body to prevent external air inflow and the upper surface of the main body).

Therefore, as shown in Figure 9, the fermentation gas generated within the fermented product packaging container sequentially passes through the communication hole 311, the filter 380, the first auxiliary communication hole 631, and the second auxiliary communication hole 632. It flows into the space between the inner space of the semicircular or oval shaped upper body to prevent outside air inflow and the upper surface of the body. Afterwards, the edge end of the outside air inflow prevention upper body 611 is lifted upward due to the discharge pressure of the fermentation gas, creating a gap between the edge end of the outside air inflow prevention upper body 611 and the upper surface of the main body 310, Fermentation gases are discharged through these gaps. Meanwhile, while the fermentation gas is being discharged, the outside air is blocked from flowing into the inside of the packaging container through the gap.

On the other hand, as shown in FIG. 8, when the fermentation gas is not discharged, the edge end of the outside air inflow prevention upper body 611 elastically restores its shape and comes into close contact with the upper surface of the body 310, thereby allowing outside air. It can block the inflow inside.

Although the present invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described. Rather, those skilled in the art will understand that numerous changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
