Description

Sealing device for the vinyl bag

The present invention relates to a stopper that effectively blocks the entrance of a plastic bag containing food and the like.

Thin plastic bags are widely used in kitchens for storing food. When food is stored in a plastic bag and stored in a refrigerator, the water may escape from the food or the smell of food may leak, so it is common to bind the opening of the plastic bag with a rubber band or tie the plastic bag to keep the inside of the plastic bag tight. to be.

It is cumbersome to use a rubber band every time to seal a plastic bag. On the other hand, when making a knot using the plastic bag itself is convenient, it is difficult to untie the knot when taking out food or replenishing the food again, so that the plastic bag is torn. Since new plastic bags are used again, waste of plastic bags is severe.

In order to solve this problem, the conventional technology such as the prior art document described later has emerged. The prior art has a body through which the vinyl passes and a stopper for screwing the spout of the body. This conventional technique has a disadvantage in that it is difficult to effectively seal the thick vinyl by overlapping as the cross-sectional area of the body and the plug is relatively smaller than that of the bag. In order to improve the airtightness, there must be no gap between the body and the screwing cap, so that the vinyl interposed in the screwed portion is excessively bitten and easily torn. In addition, since the body and the stopper are not connected to each other, it is easy to lose the stopper separated from the body. In addition, when the plastic bag is opaque, it is cumbersome to touch it or open the stopper to know the contents of the bag. In addition, since the prior art has a cylindrical body, there is a problem of rolling on the floor without the bag.

Republic of Korea Patent Publication No. 10-2004-0022292 (2004.03.12) Korea Utility Model Registration No. 20-0292376 (2002.10.04)

It should be noted, however, that the same reference numerals will be used for the same or similar components throughout the embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. It should be understood that the invention is not limited in its application to the precise form disclosed, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

1 to 6 are views related to the inlet stopper of the plastic bag according to the first embodiment of the present invention.

The stopper 100 according to the first embodiment includes a body 1 and a cap 2. The body 1 is a part connected to the inlet of the plastic bag, the cap 2 is a part sealing the inlet side of the plastic bag passed through the body while being detachably coupled with the body (1).

The body 1 includes a connecting portion 11 through which the popped inlet side of the plastic bag passes, and a trumpet-shaped guide portion 12 extending below the connecting portion 11.

The connection part 11 is formed like a substantially hollow tube. The upper end of the connecting portion 11 is formed with a pleat 112. This wrinkle part 112 can be abbreviate | omitted, The structure and function of a wrinkle part are mentioned later.

The stepped portion 111 is formed on the outer circumferential surface of the connecting portion 11. The upper part of the stepped part 111 forms an inclined surface, and the lower part is formed substantially horizontally on the cylindrical outer circumferential surface to form a stepped step.

Guide portion 12 extends from the bottom of the connecting portion. The inside of the guide part 12 is empty like the connection part 11, and the popped inlet part of a plastic bag can pass.

In addition, the guide portion 12 has a shape in which the cross-sectional area gradually increases as it moves away from the connecting portion 11. The upper end portion of the guide portion 12, which continues from the connecting portion 11, has a circular cross section, but changes downward into a rectangular cross section.

The guide part 12 is a front part 121 and rear part 122 of substantially fan-shaped shape, as long as it connects both sides of the front part 121 and both side parts of the rear part 122 with reference to drawings. It may be divided into the side portions 123 of the pair. The front portion 121 and the rear portion 122 have a trapezoidal shape when viewed from the front, and the side portion 123 has a shape close to a rectangle.

The front part 121 and the rear part 122 are formed closer to the upper part and gradually away from the lower part, and both sides are the same.

The spacing between the front part 121 and the rear part 122 is formed to be narrower than the spacing between the two side parts 123. Therefore, the width of the guide part 12 in the left-right direction is formed relatively larger than the thickness in the front-rear direction. As a result, the body 1 does not roll when laid on the floor.

Moreover, since the space | interval of the guide part is formed narrow, the space which occupies at the time of arrange | positioning a some stopper in a limited storage place becomes small. Therefore, the stopper can be connected to several plastic bags, and then placed in a narrow refrigerator.

Furthermore. The outer surface of the front portion 121 of the guide portion 12 or the outer surface of the rear portion is provided with a label 13. The label 13 may be attached like a sticker.

Alternatively, the edge of the transparent sheet may be attached to the front portion or the rear portion, and the paper may be interposed between the transparent sheet and the outer surface.

The label 13 allows the user to optionally describe the type of food or the date on which it is to be stored. Therefore, even when using an opaque plastic bag, even if you do not touch or open the plastic bag, it is possible to know the information such as what contents when contained. This label may be omitted.

On the other hand, the cap (2) is detachably coupled to the upper portion of the connecting portion, the cap (2) is a cap body 21, the lower portion is open, and protrudes from the inside of the cap body 21 and the body (1) It includes the engaging portion 22 is caught on the stepped portion (111).

The stepped portion 111 has a cylindrical base 221 extending downward from the inner ceiling of the cap body 21, and a hook 223 is formed at the end by extending downward from the end of the base 221. And engaging pieces 222. The hook 223 has both the lower surface and the upper surface formed as an inclined surface. The locking pieces 222 are formed in a plurality of radially along the circumference of the base 221.

The radially arranged locking pieces 222 may be elastically opened in the direction in which the end portions are far from each other.

When the user presses the cap 2 against the upper end of the connection part 11, the locking piece 222 is lowered while being unfolded by the inclined surface of the upper end of the stepped part 111, and the hook 223 is further pressed as the cap 2 is further pressed. ) Is stitched to the lower end of the stepped part 111. As a result, the cap 2 is coupled to the body 1.

On the other hand, when the cap 2 is pulled in a direction away from the body 1, the engaging pieces 222 are opened by the inclination of the upper surface of the hook 223 in contact with the stepped portion 111, the body (1) The cap (2) can be removed.

By pressing or pulling the cap as described above, the cap can be coupled to or detached from the body in a one-touch manner. In addition to these catches, various known configurations may be applied to couple or detach the cap to the body with one touch.

In a further configuration, the cap 2 includes a strap 23 capable of bending, and a donut-shaped hook connected to the end of the strap 23 and caught on the stepped portion 111 protruding on the outer circumferential surface of the connecting portion 11. 24) may be provided.

The strap 23 is a band extending from the outer circumferential surface of the cap 2. The strap 23 and the ring 24 may be formed together with the cap by forming a soft synthetic resin such as PET.

The ring 24 may be elastically large in diameter as it is made of soft synthetic resin. By covering the ring 24 to the connecting portion 11 and lowering it strongly, the diameter of the ring 24 increases according to the inclined surface of the stepped portion 111, and then contracts again after passing through the stepped portion 111. .

Since the diameter of the contracted ring 24 is smaller than the maximum diameter of the stepped part 111, it is caught by the stepped part 111 so as not to fall upward. In addition, since the guide part 12 is formed below the stepped part 111, the ring 24 is trapped between the stepped part 111 and the guide part 12.

As a result, the body and the cap are connected by the hook and the strap, and even if the cap is removed from the body, the risk of losing the cap or the body separately is reduced.

3 or 5 to 6 show the contact of the inner ceiling of the cap with the top of the connection.

The inner ceiling of the cap 2 projects double projections into the base 221.

The inner protrusion 211 protrudes in a trapezoidal cross section and pushes the plastic bag v covering the upper end of the connecting portion 11 toward the inner circumferential surface of the end of the connecting portion 11.

On the other hand, the outer projection 212 is responsible for folding the plastic bag (v) almost vertically.

The inner protrusion 211 and the outer protrusion 212 is to hold the shape of the plastic bag (v) to be bitten by the cap 2 and the connecting portion 11 to improve the airtightness.

The end of the connecting portion 11 enters between the inner protrusion 211 and the outer protrusion 212 and meets the ceiling of the cap 2.

Since the cap is coupled to the body in a one-touch manner, the cap coupled to the body is somewhat spaced up and down. In order to prevent the airtightness from being impaired by such play, a wrinkle 112 is provided at the end of the connecting portion 11.

The pleats 112 allow the end portions of the connecting portions 11 to be in contact with the inner ceiling of the cap 2 to elastically deform, and bend several times around the ends of the connecting portions 11 to form pleats.

In Figure 6, the wrinkles are exaggerated.

When the thick plastic bag is connected to the stopper, more plastic bags are accommodated between the cap 2 and the end of the connection part 11 by the thickness of the overlapping plastic bag v passing through the inside of the narrow connection part 11. You may need more space to do it. The pleats 112 are elastically deformed to provide space for the plastic bag v to be accommodated, and press the ends of the connecting parts 11 toward the ceiling of the cap 2. Accordingly, the end of the connection portion is pressed the plastic bag toward the ceiling of the cap is improved airtightness.

Figure 7 shows the body portion employed in the second embodiment of the present invention. The inlet stopper of the plastic bag according to the second embodiment may include the cap and the body, and may include the technical features of the above-described first embodiment without departing from the contents described below.

In the body 1 employed in the second embodiment, the thickness of the wrinkles 112 is thinner than the thickness of the wrinkles or less. The thickness of the wrinkle part 112 is formed in thickness t2 less than half compared with the thickness t1 of the part which forms the wrinkle part 112 or less.

By reducing the thickness of the wrinkle part 112 in the body 1 formed of a soft synthetic resin such as PET, the vertical elasticity of the wrinkle part 112 is further increased. Therefore, it is possible to always exhibit a stable airtight performance for a plastic bag having a variety of thickness.
