Description

Cup cover easy to exhaust internally

Technical Field

The present invention relates to a cup lid with easy internal gas exhaust, and more particularly, to a cup lid with easy internal gas exhaust while sealing the upper part of the cup body.

Background

Generally, at all stages of production and processing, post-mix roasted coffee is put into a cooling process, which has 2 methods. Namely water-cooled and air-cooled.

The water-cooled type means a method of cooling by cold water, and the air-cooled type means a method of cooling by cold air. Recently, an air-cooling type, in which coffee ingredients are less lost, is more popular than a water-cooling type.

The coffee that has undergone the cooling process finally enters the packaging stage. The coffee is contained in a cup and retains its original properties until it is effective, which is the purpose and key of packaging. Otherwise, the processed coffee loses its taste instantly. After the roasted coffee is exposed to the air, the aroma of the raw beans is volatilized together with carbon dioxide, and is exposed to oxygen and moisture in the air, and thus is inevitably oxidized.

However, many packaging containers used commercially are not tightly sealed and air and gas easily flow out and into. In this state, the coffee is degraded after several weeks, and the quality of the coffee is drastically degraded due to loss of freshness and aroma. Even premium brands of coffee are discarded after a period of time has elapsed.

The method for keeping freshness for a long time mainly uses three technologies, including valve packaging, vacuum packaging and nitrogen packaging.

Among them, vacuum packing is a method of vacuum packing ground coffee in a metal container to maintain freshness. This method has recently used a gas impermeable composite film, rather than a metal container, and in the vacuum packaging method, it is most important and most critical to maximally exhaust and block the internal air to maintain the degree of vacuum.

Nitrogen packaging is a method of extending shelf life by eliminating the air in the packaging material and then filling it with nitrogen, or replacing the internal air itself with nitrogen. The inert gas nitrogen fundamentally blocks the inflow of oxygen to thereby maximally suppress the oxidation of raw beans, but this method mainly uses an aluminum can, thus having a problem of high cost.

Both of these methods can inhibit oxidation of raw beans, but because of the high cost, the valve packing method is the most commonly used method in coffee manufacturing and distribution.

The air valve packing method is a method of preventing oxidation of raw beans by using a one-way air valve, in which an air valve called an Aroma valve (Aroma valve) or a pressure valve is attached to one end of a packing paper to move air only in one direction, so that air inside the packing paper can be discharged to the outside, but external air cannot enter the inside.

However, the wrapping paper used in the conventional valve packing method is made of vinyl material and is now being sold in large quantities, so that environmental problems are inevitable.

In order to solve the environmental problems caused by the use of vinyl materials and reduce the use amount of the vinyl materials, a scheme for conveniently keeping coffee in a paper cup or a sealed cup is needed at present.

(technical Effect)

According to the utility model discloses, easily inside gas outgoing's bowl cover combines together with cup upper end edge, inside the sealed cup, stores in the inside coffee of cup along with the lapse of time, and the oil composition removes the coffee beans surface, and at this moment, the oxygen in oil composition and the air meets, and the carbon dioxide that produces among the oxidation process passes through the discharge portion and discharges to the cup outside, and the carbon dioxide by the inside production of cup provides the effect that prevents to damage former beans after the increase of cup internal pressure.

In addition, the discharging part also allows the opening and closing membrane to cling to the circulating groove to seal the inside of the cup body when the internal pressure of the cup body is lower than or equal to the external pressure, and the opening and closing membrane moves upwards to discharge the gas formed inside outwards when the internal pressure of the cup body is higher than the external pressure, thereby keeping the taste and the fragrance of the coffee and providing the effect that the gas formed inside the cup body can be discharged outwards only.

Further, due to the internal pressure of the cup body, when the opening and closing membrane moves upward, the fixing member protrudes toward the lower portion of the cap member to contact the opening and closing membrane with the upper surface of the circulation groove, preventing the opening and closing membrane from falling off from the upper surface of the circulation groove, thereby providing an effect of conveniently sealing the inside of the cup body when the internal pressure of the cup body is lower than or equal to the external pressure.

The following will be further described in detail based on drawings attached with the technical idea of the present invention.

The drawings are merely examples for further specifically explaining the technical idea of the present invention, and therefore, the technical idea of the present invention is not limited to the forms of the drawings.

In order to clarify the gist of the present invention, it is decided to omit descriptions of known functions and configurations.

Fig. 1 is an exploded perspective view of a cup lid according to an embodiment of the present invention, showing that internal gas is easily discharged. Fig. 2 is a cross-sectional view showing a state where the cup lid and the cup body are combined to easily discharge internal gas according to an embodiment of the present invention.

As shown in fig. 1 and 2, the cup lid (1000) for easily exhausting the internal gas according to the present invention includes a lid (100), a sealing portion (200), and an exhaust portion (300).

First, the present invention provides a cup cover, which is a cup cover (1000) that is easy to discharge internal gas and is combined with the top of a cup body (10) containing a paper cup or a plastic cup to seal the inside of the cup body (10), and discharges gas containing carbon dioxide generated in the baked coffee stored inside the cup body (10) to maintain the aroma and taste of the coffee itself, but can prevent the gas from damaging the cup body (10).

At this time, the lid (100) is detachably coupled to the upper portion of the cup body (10), a circulation groove (110) is formed at one end, and as shown in fig. 1, an outflow hole (111) is formed in the circulation groove (110).

The lid portion (100) is formed in a plate shape, formed according to the size of the cup body (10), to match the size of the open top.

The circulation groove (110) is preferably formed at the center of the lid (100), a discharge part (300) to be described later is inserted and coupled, and the outlet hole (111) is preferably formed to penetrate the upper and lower portions of the circulation groove (110).

The outflow hole (111) is composed of a plurality of pieces, and gas moves outward from the inside of the cup body (10) through the outflow hole (111).

Next, the closing part (200) is formed to protrude downward from the edge of the lid part (100) and combined with the top of the cup body (10).

Specifically, the sealing part (200) is composed of a first connecting member (210) closely attached to the outer surface of the cup body (10), and a second connecting member (220) formed to protrude at a predetermined interval from the inner side of the first connecting member (210) and closely attached to the inner surface of the cup body (10); and a third coupling member formed to protrude from one end of the first coupling member (210) toward the second coupling member (220).

At this time, a hanging surface (11) formed to protrude outward is formed on the upper portion of the cup body (10) including a common paper cup or a plastic cup, and the top surface of the third coupling member (230) is coupled to the bottom surface of the hanging surface (11) in an interference fit manner to form a tight contact.

The first combination component (210) is tightly attached to the outer surface of the cup body (10), the second combination component (220) is tightly attached to the inner surface of the cup body (10) to seal the inner part of the cup body (10), and the third combination component (230) is hung on a hanging surface (11) of the cup body (10) and is responsible for fixing and preventing falling.

In addition, the fourth connecting member (240) is formed in a protruding manner on the outer surface of the second connecting member (220) and is formed at a position lower than the protruding position of the third connecting member (230), the third connecting member (230) supports the outer surface of the cup body (10), and the fourth connecting member (240) supports the inner surface of the cup body (10), so that the clinging force between the cup body (10) and the cup lid (1000) with internal gas easily exhausted is improved.

Next, as shown in fig. 3, the discharge part (300) is combined with the circulation tank (110), and includes two parts, i.e., an opening/closing membrane (310) and a cap (320).

Wherein the opening and closing film (310) is received into the circulation tank (110) to cover the outflow hole (111), a lower end surface of one side is adhered to a bottom surface of the circulation tank (110), and an upper end surface of one side contacts a lower end surface of the capping member (320).

The other lower end surface contacts the bottom surface of the circulation groove (110), the other upper end surface contacts the lower end surface of the cap member (320), and the cap member is partially cut at a position corresponding to the outflow hole (111) and pushed upward by the gas discharged from the outflow hole (111).

The opening/closing membrane (310) contacting the upper end surface of the circulation tank (110) is coated with silicone oil so as not to fall off the circulation tank (110).

Wherein the opening and closing film (310) maintains a flat shape, and even if the pressure inside the cup body (10) makes it move upward, if the gas inside the cup body (10) is discharged outward and the pressure outside and inside the cup body (10) is the same, the opening and closing film (310) contacts the upper end surface of the circulation groove (110), thereby closing the outflow hole (111).

At this time, the opening/closing film (310) may be formed of a slit film having a slit at one end, a rubber disk having an elastic rubber material, or a thin plastic material that can move upward by the internal gas pressure of the cup body (10).

Then, the cap member (320) is inserted into the circulation groove (110) and coupled to cover the opening/closing film (310), and has a discharge hole (321) formed at one end.

At this time, a screw thread is formed on the outer surface of the cap member (320), and the cap member is coupled to a screw thread correspondingly formed on the inner surface of the circulation groove (110), and one end of the cap member (320) is closely attached to the upper surface of the opening/closing film (310) to fix one end of the opening/closing film (310).

In addition, the other end of the cap member (320) is tightly combined with the upper surface of the circulation tank (110) to avoid interference with the upward and downward movement of the other end of the opening and closing membrane (310).

At this time, as shown in fig. 4, the fixing member (322) is formed to protrude downward at the central portion of the cap (320), and the fixing member (322) prevents the fixing member (322) from moving the upper central portion of the opening and closing membrane (310) upward and preventing the opening and closing membrane (310) from falling off the flow groove (100) when the other end of the opening and closing membrane (310) moves upward.

Wherein the cap member (320) has a discharge hole (321) formed at a position corresponding to the other end of the opening/closing film (310), and the other end of the opening/closing film (310) moves upward while the gas inside the cup body (10) is sequentially discharged through the outflow hole (111) and the discharge hole (321).

Next, referring to FIG. 5, the step of exhausting the internal gas of the cup body (10) by the cup cover (1000) which is easy to exhaust the internal gas of the utility model is examined,

fig. 5 (a) is a view showing a state where roasted coffee is poured into the cup body (10); (b) is a state diagram of the gas which contains the carbon dioxide generated by the oxidation of the roasted caffeine and is generated in the cup body (10) so as to increase the internal pressure of the cup body (10); (c) the state diagram shows that the internal pressure and the external pressure of the cup body (10) are the same after the gas in the cup body (10) is exhausted.

The upper and lower parts of the cup lid (1000) in which the internal gas is easily discharged are acted by the external atmospheric pressure (F1), the pressure (F2) generated inside the cup body (10), the adhesive force (F3) of the opening and closing film (310), and the elastic force (F4) of the opening and closing film (310).

In fig. 5 (a), in a state where the initially roasted coffee is put into the cup body (10), the external atmospheric pressure (F1) and the internal pressure (F2) of the cup body (10) are the same, and therefore, the outflow hole (111) is kept closed by the adhesive force (F3) of the opening/closing film (310) and the elastic force (F4) of the opening/closing film (310), and the cup body (10) is kept sealed.

Next, as shown in (b), the roasted coffee stored in the cup body (10) generates gas containing carbon dioxide after a certain period of time, and at this time, the internal pressure (F2) of the cup body (10) is higher than the sum of the external atmospheric pressure (F1), the adhesive force (F3) and the elastic force (F4) of the opening and closing film (310), so that the other end of the opening and closing film (310) moves upward, thereby exhausting the gas in the cup body (10) to the outside.

Further, as shown in (c), since the gas generated inside the cup body (10) is discharged to the outside and the internal pressure (F2) is equal to or lower than the sum of the external atmospheric pressure (F1) and the elastic force of the opening/closing membrane (310), the opening/closing membrane (310) is closely attached to the flow channel (110), the outflow hole (111) is closed, and the cup body (10) is maintained in a sealed state again.

Thus, the gas is generated from the roasted coffee stored in the cup body (10) along with the time, the gas in the cup body (10) moves upwards to the opening and closing film (310) due to the internal pressure, so that the gas in the cup body (10) is discharged, and the external gas is prevented from entering the interior, thereby providing the effect of preventing the roasted coffee from oxidative deterioration.

The present invention is not limited to the preferred embodiments, and can be applied widely, and various changes can be made within the scope not departing from the gist of the present invention claimed in the claims.
