The present invention forms a storage space blocked from the outside by combining with the target means such as a container such as a dish or bowl,

Due to its elastic properties, it can move in the direction of reducing the volume of the storage space to exhaust the air in the storage space, thereby improving the sealing property.

It relates to a vacuum cover that can delay the food is stored in the storage space is in contact with the air decay,

In particular, the present invention is made of an elastomer such as silicone rubber, a member for improving the sealing property on the contact surface with the target means, or even a valve for intake or exhaust is integrally manufactured.

Separate conventional vacuum cover is made of a combination of the individual members, the food debris from the food or the gap between the member and the member or fine food accumulates remaining to harm the hygiene

In addition, since the covers of conventional food containers are made of synthetic resin, there is no problem of avoiding consumption because it is pointed out as a source of life of environmental hormone which is becoming a problem recently.

It relates to a vacuum cover.

In storing foods such as fruits, vegetables, and leftovers, the air inside the container is discharged to delay oxidation by aerobic microorganisms to extend the shelf life of stored foods,

To prevent the smell of food or the smell of other food

Recently, a vacuum container used by evacuating air inside a container beyond a simple sealed container has been in the spotlight.

Also, among the vacuum containers, the type used in the method of discharging the air inside the container using a separate electric pump type vacuum device, such as Ahn Jun-young's Republic of Korea Utility Model Registration No. 0395836 (2005.09.07) `` Vacuum container cover '',

Kim Hyung-jun and one other person registered a Korean Utility Model No. 042438 (2005.11.24), such as Vacuum Packaging Container, which has a kind of exhaust piston like a syringe in the container itself.

However, these types of things have not been commercially successful to replace or encroach on simple sealed containers as a major drawback of complicated use.

Furthermore, although the degree of vacuum inside the container does not reach the technical level of the above two documents using separate vacuum devices, it is possible to discharge the air inside the container to some extent with the main purpose of ease of use, thereby obtaining a food oxidation delay effect.

Utility Model Registration No. 0389341 (2005.07.01), consisting of a hard upper pressurized lid and a silicone wrap cover at the bottom, "A sealed lid for compressed vacuum of containers",

Patent registration No. 0526358 (2005.10.28) of Saesam Co., Ltd., where wrinkles are formed to achieve elasticity

An elastic cover is proposed to move in a direction to reduce the volume of the storage space generated by the combination of the container and the cover to allow the air in the storage space to be discharged.

However, an elastic vacuum cover that performs such a pump function replaces an existing sealed container such as Hana Kobi Corporation's patent registration No. 0452886 (2004.10.05), `` A sealed container for storing food with safety handles, '' or a separate demand from the sealed container. To create

While ensuring good sealing,

Recently, as a major concern of consumers, the content of polystyrene oligomer, bisphenol A, and phthalic acid compound used as a plasticizer of plastic products, which is mainly studied as an environmental hormone suspected substance which is an alias of endocrine disruptor, Beyond nothing

It is necessary to present food containers and covers that do not use organic synthetic resins.

On the other hand, although the container itself is a product that is marketed and spotlighted by using a heat-resistant glass material to eliminate concerns about environmental hormones,

Still, the cover is inevitably using synthetic resin products in consideration of cost competitiveness and sealing.

Therefore, the present invention has been proposed to provide a vacuum cover which prevents food oxidization through low level storage space vacuum while ensuring a tightness corresponding to an existing airtight container without any problem of environmental hormone leakage.

To this end, the present invention is composed of an elastomer (particularly, silicone rubber) and has no problem of environmental hormone, and also has excellent heat resistance. An object of the present invention is to provide a vacuum cover which is also free from water generation.

It is another object of the present invention to provide a vacuum cover of various models that can be applied to both a bowl-type dish, a dish-type vessel, or a countermeasure such as a dining table covered with glass panels.

Furthermore, the present invention provides a vacuum cover which is integrally formed on the cover body, even a skirt or a sealing protrusion for enhancing sealing, arranged on the contact surface with the corresponding means, and even a valve for intake or exhaust in the storage space. ,

It is an object of the present invention to provide a vacuum cover that does not have a problem that food packing wastes or accumulates in the gap between the ring and the cover when the packing ring and the cover are combined (adhesive or tight fit) like the conventional airtight container. It is done.

In addition, the present invention, even if made of a material having the same physical properties, there is a difference in the thickness of each part to improve the sealability with the container (in the case of the rear-skirt),

Ensures tightness through quick engagement and strong bite force when returning after opening the valve (for rear-integral valves),

In addition to the seal made at the edge contact area as originally formed, various functionalities such as introduction of a site where the shape changes during vacuum evacuation and can be contacted with the countermeasure once more (in the case of a thin section-border) are differentiated in thickness. It is an object to provide a vacuum cover implemented by.

Vacuum cover according to the present invention to achieve the above object is

An elastic body that blocks the storage space from the outside and performs an exhaust or intake function with respect to the storage space according to the displacement form; And

And a valve provided in the main body for discharging gas in the storage space or inflowing gas into the storage space, or both.

In addition, the vacuum cover according to the present invention is for the main body (united) valve

In addition, the outer boundary portion of the corresponding means for forming a storage space blocked with the outside together with the main body and the main body is formed with a departure-avoidance portion that is male and female mutually coupled to the contact surface,

It is preferable that an extended skirt is formed at an outer edge of the main body.

Furthermore, a relatively thin thin portion is formed inside the rim of the main body, which is in contact with the corresponding means for forming a storage space blocked from the outside together with the main body. It is preferable that it can contribute to the improvement of sealing property.

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

In the drawings, the same reference numerals, in particular, reference numerals in which Arabic numerals coincide indicate members having the same function, and unless otherwise specified, members referred to by reference numerals in the drawings may be regarded as members conforming to these criteria.

The cover and body according to the invention

According to the shape, it can be divided into dome type and flat type,

In addition, the cover is coupled to the vacuum cover according to the present invention to form a storage space blocked outside, in particular inscribed (inscribed) type and the outer surface of the container in contact with the border of the container in accordance with the shape of the container and the border portion in contact with the cover Can be divided into a circumscribed form where the borders of (the inscribed and circumscribed terms are based on containers),

The reference numerals for the cover and the body are referred to according to these criteria, ignoring the detailed differences (Ccd, Cif, Ccf and Ccf ').

In addition, valves for discharging air in the storage space or introducing air into the storage space are also integrally injection molded and separately manufactured and combined (including a double injection type) in a detachable form (disunited). (Vu and Vd).

In addition, the article to be combined with the vacuum cover in the present invention will usually be a bowl (bowl) or a dish (dish) of the container, but the domed cover (Ccd) shown in Figure 1a is a smooth surface (for example, glass panel) provided on the table, etc. Since it is possible to form a storage space to cover, the term 'responsive means' is used in this specification to encompass this concept.

In the present specification, a 'skirt' 11 is a term used to collectively refer to a portion of the vacuum cover model that extends the edge of the main body to surround the outer surface of the container.

The main body or valve of the vacuum cover according to the present invention, or both of them use an elastomer, in particular, silicone rubber, which is excellent in heat resistance and does not have environmental hormone problems.

Due to the unique elasticity of the material, it can serve as a pump for releasing air in the storage space and air intake into the interior space.

First, the vacuum cover (Ccd) shown in Figures 1a, 1b, 1c, 1d and 1e is provided with a dome-type vacuum cover and an integrated valve according to the first aspect of the present invention. .

1A and 1B, the vacuum cover (Ccd) shown mainly covers a dish type container or

It is a model that is used to put a container with food on the glass panel of the table and cover the entire container.

First, in the drawing, the main body Bcd has a dome shape, and the edge has a skirt 11 so as to surround the outer lower portion of the dish-shaped container Cd, and the separation prevention of the form of being male and female combined with the container. The part 12 is formed.

Together with the main body Bcd, the countermeasure, in particular, the dish-shaped container Cd forms a storage space S which is blocked from the outside.

When pressurizing the main body (Bcd) to discharge the air in the storage space (S) through the rim of the main body or through the valve (Vu)

According to the volume reduction of the storage space, the body made of an elastomeric material shrinks and deforms.

The air discharge in the storage space S increases not only the coupling force between the contact surface of the dish-shaped container Cd and the cover (particularly, the separation prevention portion 12 and the skirt 11 of the dish-shaped container and the main body). It is difficult to separate the cover even if the force is applied up and down due to the coupling form),

Due to the shrinkage deformation of the main body, relatively thin thin portions 14 are in contact with the upper surface of the dish-shaped container Cd, compared to other portions arranged inside the edge of the main body Bcd. In addition to 12, the thin portion 14 may perform a double sealing function.

Next, an integrally injected valve Vu is provided at the center of the main body Bcd. In particular, a recess 15 is formed around the valve to prevent protrusion of the valve Vu.

The valve Vu may be used for gas discharge in the storage space S or gas inflow into the storage space, or both.

When the valve Vu and the main body Bcd are pressurized in the illustrated domed cover Ccd, air is discharged from the storage space by a gap between the edge of the main body and the container Cd,

In some cases, the valve is mainly used for gas inflow into the storage space, and the gas discharge may be exhausted while a gap is formed between the edge of the main body and the container Cd when the main body Bcd is pressurized.

The valve (Vu) is surrounded by the depression 15 of the main body and is provided with a protruding pressing portion 21 that maintains substantially the same height as the upper surface of the main body,

It consists of an intake and exhaust part 22 incision (incised) on the upper surface of the pressing portion (21).

As shown in the enlarged circle " A " of FIG. 1A, the intake and exhaust sections 22 are cut in the vertical direction,

As can be seen from the plan view of FIG. 1C [A] and the bottom view of [B], a straight line is formed.

When pressing the cover (Ccd) and the dish-shaped container (Cd) of the first aspect (aspect) to press the pressing portion 21,

In particular, as shown in Figure 1b by pressing both ends of the intake and exhaust part 22 toward the incision direction to open the air in and then separated.

The outer shape of the valve (Vu) pressing portion 21 is approximately truncated conical shape,

Indeed, the exhaust passage 22a toward the intake and exhaust section 22 is shaped like an upper and lower beam, more precisely as shown in the enlarged circle "B" in FIG. It has the same shape as the abbreviated representation of the house provided.

Due to the upper and lower light exhaust passages 22a, the wall thicknesses of the adjacent portions of the intake and exhaust sections 22 form a thicker rear portion 21a to be elastic in the direction in which the intake and exhaust sections 22 of the valve are closed. This easy-to-operate feature ensures quick engagement and strong bite force upon return after valve opening.

A state in which the vacuum cover of the first form shown in FIG. 1A is applied to a bowl-type container Cb is illustrated in FIG. 1D, and the storage space exhaust vacuum is caused by the thin portion 14 around the edge of the cover body Bcd. When the bottom of the thin portion is in contact with the upper inner surface of the container (Cb) can also be improved sealing.

In the present invention, the vacuum cover (Ccd) of the first aspect is a modification,

As shown in the enlarged circle “C” of FIG. 1A, the inlet / outlet cut-out of the valve Vu is not vertical, but is an oblique line 22A, so that the air flowing in and out of the vertical direction is more completely blocked. To be done.

Furthermore, in Fig. 1e, various intake and exhaust sections 22 of the valve are shown, where [A] is a toothed incision, [B] is a curved incision, [C] is a two straight incision, and [D] is a two angle All of the incisions are designed to improve the sealability in the state where the intake and exhaust parts are closed.

Next, FIG. 2A shows a flat vacuum cover (Cif) according to the second aspect of the present invention, but also has an integrated valve (Vu), but a model in which the bowl-type container (Cd) and the rim are inscribed. It is.

In FIG. 2A, a depression 15 is also formed in the cover body Bif around the valve Vu.

A sealing protrusion 13 is formed at a portion in contact with the inner surface of the bowl-type container Cd, which is a kind of countermeasure means.

In addition, the airtight layer 13a is formed on the contact surface with the container Cd by the sealing protrusion to improve the sealing property.

The air layer 13a is actually surrounded by the flange 13A of the cover body Bif and the inner wall of the sealing protrusion 13 and the container Cb.

If necessary, when the sealing protrusions 13 are two or more, the air layer is further formed by being surrounded by the protrusions, the protrusions and the inner wall of the container.

In addition, the flange (13A) of the cover body is further protruded outward compared to the container to serve as a container and the cover separator yarn grip,

The thickness of the flange (13A) is thicker than other parts while reducing the material consumption

Even when the cover is pressed on the upper end of the container to evacuate the storage space S, the cover is optimally provided to provide a support force such that the cover does not fall into the container.

When pressurizing the cover body (Bif) to discharge the air in the storage space (S), the air is discharged through the valve, or is also discharged while opening the gap between the rim of the body and the container, or both All routes can be released by vomiting.

Subsequently, in FIG. 2B, unlike the shape shown in FIG. 2A, the vacuum cover Ccf is deformed to surround the outer surface of the bowl-type container Cb,

The sealing protrusion 13 and the air layer 13a are also arranged and formed accordingly.

In addition, the thin portion 14 is formed around the rim 13A in FIG. 2C, compared to FIG. 2B, and the thin portion 14 is in close contact with the upper inner wall of the bowl-type container Cb when the storage space S is vacuumed. Is deformed.

In FIG. 2D, the intermediate form of FIGS. 2A and 2B is mainly provided with an extension sleeve 11A contacting the inner surface of the container in addition to the skirt 11 surrounding the outer surface of the container Cd.

Next, FIGS. 3A and 3B show a coupling plan view and a coupling cross section of the vacuum cover and the bowl-type container, each having a disunited valve Vd according to the third aspect of the present invention.

3A [A] and [B] show rectangular and circular covers (Ccf) for rectangular and circular bowl containers, respectively.

As shown in Figure 3a and 3b, the bowl-type container (Cb) has a continuous or discontinuous departure prevention portion 31 is formed on the upper outer peripheral surface, the cover (Ccf) body (Bcf) the number (雄) A corresponding arm separation prevention portion 12 engaged with the separation prevention portion 31 is formed on the inner circumferential surface of the skirt 11.

In addition, the inner bottom of the skirt 11 of the main body is inclined, and the container Cb is also inclined in its outer wall, whereby relative shapes are combined to form a finger insertion gap 12a at the boundary surface, thereby forming the cover and the container. It is easy to remove.

The cover (Ccf) body (Bcf) rim portion and skirt 11 portion is thicker than the inner portion thereof can be combined with the container with a strong bonding force, possible separation of the container and the cover can be prevented as possible and contribute to improved sealing It is supposed to.

On the other hand, a valve (Vd) mounting hole 16 is formed in the center of the body (Bcf), four air discharge holes 17 are formed around the mounting hole (16).

The detachable valve Vd is connected to the fitting part 27 inserted into the installation hole 16 of the main body Bcf, a fixing part 25 in contact with the lower surface of the main body and positioned below the joint part, and the upper surface of the main body Bcf. Located in the surface contact form and comprises a blocking portion covering the air discharge hole 17 formed in the main body,

Such a valve is also provided in the depression of the main body to prevent the protrusion.

When the cover Ccf as described above presses the body Bcf coupled with the container to discharge the air in the storage space S, the air is mainly the air discharge hole 17 due to the arrangement of the blocking part 23 of the valve. Is discharged through).

In addition, when the cover is removed from the container, in order to introduce the air in advance, it is necessary to lift the blocking portion 23 of the valve.
The inflow and discharge of air into the storage space S as described above is made easier and more effective since the valve Vd is made of an elastomeric material such as a main body.
That is, when the vacuum is applied to the storage space, if the upper surface of the cover (Ccf) body (Bcf) coupled with the container is pressed, the air in the storage space through the air discharge hole (17) by the pressurized force More specifically, the valve made of an elastomer material is discharged to the outside, and more specifically, the blocking part 23 of the valve is lifted up, and after the air is discharged, the lifting part 23 is naturally lowered and the storage space S and Vacuum is applied as the airtight is achieved.
On the contrary, if the vacuum is to be released while the vacuum is applied, it is only necessary to lift the shut-off portion 23 of the valve made of an elastomeric material by hand.
More preferably, in order to increase the performance of the valve (Vd) for the air flow in and out, and to improve the airtightness to the storage space (S), as shown in Figure 3b, the blocking portion 23 of the valve (Vd) It is desirable to make the thickness thinner toward the edge.

Figures 4a and 4b is a cross-sectional view of the main portion of the vacuum cover having a separate valve showing a major difference in that the gripping portion compared to the valve shown in Figure 3b,

The valve Vd shown in FIG. 4A differs in that the grip portion 23A is simply formed to protrude.

In addition to the grip portion 23A, the valve Vd illustrated in FIG. 4B has a length such that the joint portion 27 can move up and down with respect to the main body Bcf.

In addition, the air discharge hole 17A of the main body Bcf shown in FIG. 4B serves as a valve installation hole, and the exhaust slit 25A formed in the fixing portion 25 of the valve Vd and the main body Bcf. Air is discharged through the air discharge hole 17A,

When the air is discharged from the storage space or the air is introduced into the storage space, the gripping portion 23A should be pulled out so that the blocking portion 23 is separated from the main body Bcf.

In the form shown in Fig. 4b, it is preferable that the valve cannot be arbitrarily rotated so that the exhaust slit 25A and the air discharge hole 17A of the main body are always matched.

This can be implemented, for example, in the form of a non-circular shape (eg, semi-circular, triangular, square, etc.) of the cross section of the joint 27 and the air outlet 17 of the body.

In addition, it is preferable that the blocking portion 23 of the valve is implemented in a form in which the stop of the valve is made at a position where the air discharge hole 17 of the main body is closed and opened.

This can be implemented, for example, by forming a stopper at the upper and lower positions of the joint part 27 of the valve.

As described above, the vacuum cover according to the present invention is made of an elastomer, in particular, silicone rubber, and has no environmental hormone problem, and also has excellent heat resistance. It is possible to provide various models of vacuum covers, which can be applied to both countermeasures such as a bowl-type container, a dish-type container, or a table covered with a glass panel, and there is no fear of leaking and no spillage. Furthermore, by providing a vacuum cover that is integrally formed in the cover body, even a skirt or a sealing protrusion for enhancing sealing property, which is arranged on the contact surface with the corresponding means, and even a valve for intake or exhaust in the storage space, The packing ring and the cover are combined together like a container (adhesion or interference fit) In the case of the formed form, there is no problem that food waste gets stuck or accumulates in the gap between the ring and the cover, and there is no problem of causing hygiene problems. (For rear-skirt), to ensure fast sealing and strong bite force when returning after valve opening (for rear-integrated valves), at the edge contact as originally molded In addition to the sealing, the shape is changed during vacuum evacuation, so that various functionalities such as introduction of a site (in the case of a thin section-border) that can be in contact with the countermeasure once more can be realized by thickness difference.

In the above description, the conventionally known techniques related to elastomers, in particular, silicone rubbers, which have no specific physical properties or harmful grades, are omitted, but those skilled in the art will naturally be able to infer and deduce them.

In addition, in the above description of the present invention, the vacuum cover having a specific shape and structure has been mainly described with reference to the accompanying drawings. However, the characteristics of each cover body and the valve of the present invention may be variously modified and modified by those skilled in the art. Modifications are possible, and such modifications and variations should be interpreted as falling within the protection scope of the present invention.
