Description

Double locking container {DOUBLE LOCKING CONTAINER}

The present invention relates to a double locking container, and more particularly, to the body of a container used to store food, etc., the lid is coupled in a double locking (sealed) structure through internal insertion to improve airtightness, and leakage of contents or odors It relates to a double locking container that does not occur and allows to increase the storage period of the contents through sealing.

As a container for storing food, such as side dishes, the most common container has a pressing protrusion protruding from the top of the side wall of the main body, and a fitting groove is formed in the rim of the lid correspondingly. It is a form in which the lid is coupled and airtight while being inserted into the fitting groove.

However, since the above-mentioned general container does not have excellent airtightness, it is easy to leak food or odor, so there is a limit in storing food with broth.

A typical example to solve this problem is a container type that secures airtightness with internal packing while the so-called "Lock and Lock" lid is equipped with a separate locking blade, and when the lid is closed, the locking blade is folded and caught on the stumbling block of the container (for reference, Lock and Lock). As a brand of container products, it does not mean only containers with the LOCK&LOCK brand name, but similarly refers to all container products that secure airtightness by pressurizing the inner packing using locking blades).

In the above container type, airtightness can be secured by completely sealing the gap between the container and the lid while the inner packing of the lid is pressed with a strong pressure on the pressure protrusion of the side wall part due to the locking blade. However, this type of container has the following problems have.

First of all, the above-mentioned "Lock and Lock" type container has a separate mounting groove on the rim of the lid for mounting the inner packing, and the broth of food seeps between the inner packing and the mounting groove and is not easily washed, causing mold, etc. It is easy to do, and even if the inner packing is separated, food on the packing is not completely removed due to the nature of the rubber material of the packing itself, so there is a problem that the packing is contaminated during long-term use.

Furthermore, if the packing is frequently separated from the lid for washing, the elasticity of the packing itself is lowered, and there is a problem in that the airtightness of the packing itself is lowered due to damage occurring during washing.

In addition, in the case of locking blades, due to repeated folding and unfolding operations, the coupling force of the locking blades is likely to decrease as the connection strength is loosened, and the pressing force on the parts to which the locking blades are not connected is relatively higher than that for the parts where the locking blades are connected. Because it falls, in the case of a large container, there is a disadvantage that the size or number of locking blades must be increased together.

Accordingly, the present invention has been devised to solve the above problems,

The lid is coupled to the main body of the container used to store food in a double locking (sealing) structure through internal insertion to improve airtightness, thereby increasing the storage period of the contents through sealing without leakage of contents or odors. An object of the present invention is to provide a double locking container that allows

Double locking container according to the present invention,

As the lid is inserted into the main body, airtightness is secured with a double locking (sealing) structure for the entire circumference of the opening to prevent food, especially side dishes with broth, from leaking out of the container or from leaking odors,

Since there is no separate locking blade or packing, the airtightness is not deteriorated even after long-term use, and the manufacturing cost can be reduced compared to the conventional "lock and lock" type container.

When the same container is stacked and stored, the stacking height is lowered due to the groove structure of the insert, and containers can be safely stacked and stored.

It has a structure in which the body and each flange of the lid are fitted with a male and female connection to each other, so the bonding force of the lid is improved, and at the same time, the opening of the lid is quick and easy.

There is no risk of damage because the shape of the body and lid is not easily deformed by strength reinforcement using the embossing part.

There is an effect that can prevent the lid from being completely closed properly by easily checking the airtight state while safely and accurately sealing the main body with the lid by preventing over-insertion or non-insertion of the insertion part.

Hereinafter, a double locking container according to the present invention will be described with reference to the accompanying drawings.

The present invention, as shown in Figures 1 and 2,

a main body 10 having a bottom portion 12 forming a storage portion 11, a side wall portion 13, and a fitting portion 14 connected from the upper end of the side wall portion 13 to the top;

a lid 20 having an insertion portion 21 protruding downward to fit into the fitting portion 14; and

A locking means for allowing the insertion portion 21 to be coupled to the fitting portion 14 by force fitting; including,

The locking means,

A pair of locking grooves 141 and 142 formed concavely along the circumferential direction on the inner surface of the fitting portion 14 and arranged in two vertical rows;

It is formed to protrude along the circumferential direction from the outer surface of the insertion part 21 and includes a pair of locking protrusions 211 and 212 respectively fitted into the pair of locking grooves 141 and 142 .

The main body 10 and the lid 20 are injection-molded with a plastic-like synthetic resin material, and have an elastic force enough to deform their shape when an external pressure is applied.

The body 10 may have a rectangular container shape as shown in the drawings, as well as a circular container shape (not shown), and in this specification, a first seating part 17 and a second seating part 17 and second to be described later for convenience of understanding Wings 23 are described on behalf of a rectangular container in a form provided in the corner of the container, but the interpretation of the rights of the present invention should not be limited.

Again, the fitting portion 14 includes a support end 14a that is bent outwardly from the upper end of the side wall portion 13 to support the bottom edge of the insertion portion 21, and the support end 14a. It is connected by bending from the outer end to the upper portion and includes a convex forming portion (14b) forming the pair of locking grooves (141, 142).

At this time, the height of the fitting portion 14 is formed to be the same as the protrusion height of the insertion portion 21, and when the lower edge of the insertion portion 21 is caught on the support end 14a, the lid 20 is closed. As the insertion part 21 is excessively inserted, the second flange part 22 to the second wing part 23 to be described later are prevented from being deformed.

The insertion part 21 is formed by pressing the central cover part 21a except for the edge of the lid 20 concavely downward, and is a fitting groove surrounded by the wall part 21b on the upper part of the insertion part 21 . (21c) is formed, when the containers are stacked up and down and stored, the body 10 of the other container is fitted and coupled to the fitting groove 21c.

The locking grooves 141 and 142 and the locking protrusions 211 and 212 are ring types formed along the circumferential direction of the fitting portion 14 and the insertion portion 21, respectively, and have the same width and depth (height). It consists of a first locking groove 141 and a first locking protrusion 211 on the upper side, and a second locking groove 142 and a second locking protrusion 212 on the lower side.

Therefore, when the insertion part 21 of the lid 20 is inserted into the fitting part 14 and closed, the convex molding part 14b is opened outward by the pressing of the locking protrusion parts 211 and 212, and the insertion part ( 21) is inserted, and at this time, the first and second locking protrusions 211 and 212 are sequentially inserted into the first and second locking grooves 141 and 142 while the convex molding portion 14b is elastically returned. The lid 20 is coupled to the main body 10 in an interlocking manner, thereby completing a double locking (sealing) structure.

This locking means, even without a separate locking blade or packing, due to the uneven structure of the locking grooves 141 and 142 and the locking protrusions 211 and 212, the lid 20 is not easily separated. By sealing the gap between the insertion part 21 and the fitting part 14 in a vertical double structure, it is possible to secure airtightness like a "lock and lock" type container.

Then, the main body 10 is connected to the first flange portion 15 bent outwardly from the upper end of the fitting portion 14, and a portion of the outer end of the first flange portion 15 is connected to protrude outward. It includes a plurality of first wing portions 16, a plurality of first seating portions 17 formed between the first wing portions 16,

The lid 20 is a second flange portion 22 supported by the first flange portion 15 by being bent outwardly from the upper end of the insertion portion 21 , the second flange portion 22 . A plurality of second wing portions 23 and second wing portions 23 protruding outwardly from a portion corresponding to the first seating portion 17 among the outer ends and fitted into the first seating portion 17 . It includes a plurality of second seating portions 24 formed therebetween to which the first wing portions 16 are fitted.

Referring to the drawings, the first flange portion 15 is formed by being bent and connected in the outer horizontal direction along the upper edge of the body 10 , and the first flange portion 15 is formed in the remaining section except for the corner portion of the first flange portion 15 . The wing portion 16 extends and protrudes in the horizontal direction, so that the first seating portion 17 is formed between the first wing portions 16 , that is, at the corner of the body 10 .

In addition, the lid 20 is formed by bending the second flange portion 22 in the outer horizontal direction along the upper edge of the insertion portion 21 to correspond to the first flange portion 15, and the second wing The part 23 and the second seating part 24 are alternately arranged to correspond to the first seating part 17 and the first wing part 16, respectively, so that the wing parts 16 and 23 and the seating part ( 17) and 24 are fitted with each other.

Therefore, with the double fitting structure of the first wing part 16 and the second seating part 24, the first seating part 17 and the second wing part 23, the coupling of the lid 20 is more firmly maintained. At this time, the second wing part 23 functions as a kind of handle, holding the first wing part 16 and holding the second wing part 23 as if tearing off the second wing part 23 to suppress the insertion part 21 in the fitting part 14 . By subtraction, the lid 20 is opened.

At this time, the outer edge end of the first flange portion 15 and the first wing portion 16 is formed as a downwardly bent skirt portion (S) to increase its own rigidity.

Further, the main body 10 is formed to protrude upward from the first wing portion 16, and a first embossed portion 161 into which the outer ends of the second flange portion 22 and the second wing portion 23 are fitted. ), including

The lid 20 includes a second embossing portion 231 protruding upward from the second wing portion 23 .

The first and second embossing portions 161 and 231 form skirt-shaped embossing during injection molding of the main body 10 and the lid 20, and the first and second wing portions 16 having a thin thickness. (23) to increase its own rigidity.

In addition, a third embossing portion 221 protruding upwardly may also be provided on the second flange portion 22 .

The first to third embossing portions 161, 231, and 221 give each of the flange portions and the wing portions a predetermined thickness, thereby preventing deformation due to external pressure.

This is that when one or more of the second flange part 22 and the wing parts 16 and 23 is bent upward or downward and deformed, the above-described double fitting structure is not completed, so that the coupling force of the lid 20 is reduced. in order to prevent

In addition, in the case of the first embossing part 161 , the outer ends of the second flange part 22 and the second wing part 23 are fitted while being in contact to further improve the coupling force of the lid 20 .

On the other hand, in the present invention, when the insertion part 21 is completely fitted up to the support end 14a, the locking protrusions 211 and 212 are completely inserted into the locking grooves 141 and 142 to double When the locking structure is completed, because it is difficult to identify the outside of the insertion portion 21 by mistake, if a part of the insertion portion 21 is not completely inserted (for example, one of the corners of the lid 20 is completely If the second locking protrusion 212 is inserted into the first locking groove 141 because it is not inserted, airtightness may be reduced.

Accordingly, the present invention further includes a sealing identification means for external identification of the complete fitting of the insert (21).

As shown in Figure 3,

The sealing identification means is provided with a shaft portion 162 protruding downward from the bottom of the portion where the one side wall portion 161a of the first embossing portion 161 is connected in the first wing portion 16,

A first through-hole 163 and a second through-hole 164 formed through the first wing portion 16 and one side wall portion 161a of the first embossed portion 161, respectively;

It has a rotating shaft 165a that is axially installed on the shaft 162, a pressing portion 165b capable of retracting and retracting through the first through hole 163, and a locking portion 165c capable of retracting and retracting through the second through hole 164. However, when the pressing portion 165b is withdrawn to the upper portion of the first through-hole 163 when rotating in one direction, the engaging portion 165c is drawn into the second through-hole 164, and when rotating in the other direction, the Including an identification member 165 through which the holding portion 165c is drawn out of the second through hole 164 while the pressing portion 165b is drawn into the first through hole 163,

When the lid 20 is closed, the second wing part 23 presses the pressing part 165b so that the locking part 165c is drawn out to the upper part of the second wing part 23, so that the identification of the sealed state is difficult. characterized as possible.

The shaft portion 162 protrudes from the bottom edge portion where the first wing portion 161 and the one side wall portion 161a meet,

The first through-hole 163 and the second through-hole 164 are formed by being perforated in a long groove shape.

The identification member 165 is provided with the rotation shaft 165a in the center and is axially installed on the shaft portion 162, and the pressing portion 165b protruding upward on one side with respect to the rotation shaft 165a is provided, The locking part 165c protruding in the horizontal direction is provided on the other side, and in this case, the pressing part 165b and the locking part 165c protrude in a curved shape.

In addition, the pressing portion 165b and the engaging portion 165c are provided with a cam inclined surface tapered at a predetermined angle on one side thereof.

The identification member 165 may be elastically supported by a separate elastic body (not shown) so that the pressing part 165b is drawn out into the first through hole 163 and protrudes when no external pressure is applied.

Accordingly, in a state in which the identification member 165 is rotated in one direction, the locking part 165c is hidden inside the embossing part so as not to interfere with the fitting of the second wing part 23 .

And when the lid 20 is inserted into the main body 10 and closed, the bottom surface of the second wing part 23 is pressed as the second wing part 23 is fitted into the second seating part 24 . Pressing the portion 165b, the identification member 165 rotates in the other direction as a reaction to this, and the engaging portion 165c is drawn out of the second through hole 164,

Only when the insertion part 21 is completely inserted, the locking part 165c is exposed while covering the upper surface of the second wing part 23 .

Therefore, the user can completely seal the lid 20 by immediately identifying that the lid 20 is not completely sealed if the engaging portion 165c is not identified with the upper surface of the second wing portion 23 when the lid 20 is closed. In addition, the second wing portion 23 is caught by the engaging portion 165c during the sealing of the lid 20 to increase the bonding force of the lid 20 .

In addition, when one of the second wing parts 23 is held and the lid 20 is opened, the pressure on the pressing part 165b is released and the second wing part 23, which is lifted, presses the cam inclined surface. The identification member 165 is rotated back to its original position, so that the lid 20 can be separated.

At this time, when the locking part 165c and the second pressing part 165b are formed in complementary colors, the identification of the locking part 165c becomes easier.
