Description

Vial sealing structure with flip-off cap and its manufacturing method {STRUCTURE FOR SEALING OF VIAL WITH FLIP-OFF TYPE CAP AND MANUFACTURING METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vial sealing structure with a flip off cap, and more particularly to a flip off cap that is designed to safely and easily detach a small plastic cap from a sleeve. A vial sealing structure and a method of manufacturing the same.

In general, the vial is a storage container for various contents that must be sterilized, such as injection liquid, powder injection, contact lens, etc., and is sealed to prevent leakage and deterioration of contents stored in the container and to prevent foreign substances from entering the outside. It is shaped in various forms for safe storage and transport.

Such vials are formed for small packages, such as muscle relaxants, anesthetics, antibiotics, etc., or for medium and large packages, such as infusions and intravenous injections. In particular, in the case of small vials, a precise machining device is required when manufacturing a sleeve that serves as a sealing.

A general vial 1 as shown in FIG. 1A is formed of a sterile, antimicrobial-treated glass material or a plastic material that has passed a predetermined drug container test method and has a vial 2 having a bottle shape for storing contents therein. Have At the inlet 3 of this vial 2, a stopper (not shown), such as a septum, is inserted into the inner diameter of a sterile, antimicrobial rubber, and Teflon (PTFE: PolyteTraFluoroEthylene) material.

In the vial flip-off type cap structure according to the prior art, a silver, aluminum sleeve 4 is provided around the inlet 3 of the vial 1 so that the cap is not separated from the vial 1. It is clamped, and a flip-off type plastic cap 5 is coupled to the upper surface of the sleeve 4.

As shown in Fig. 1B, the flip-off type plastic cap 5 and the sleeve 4 insert a fixed shaft 11 formed in the cap shaft core into a fixing hole formed in the sleeve shaft core, and then a device such as a hot pressing press. By using, the fixed shaft 11 is melted so as to spread in the circumferential direction and compressed, so as not to be separated from each other.

At this time, the upper surface 6 of the sleeve 4 is formed with a circular groove 7 recessed inward, and the circumferential side of the circular groove 7 has a finite length and maintains a predetermined distance 8a from each other. A plurality of protrusions 8 are formed in the circumferential direction. In the inner portion in contact with the protruding pieces 8, cutting lines 9 having a pointed triangular shape and being nearly circular in shape are formed between predetermined intervals 8a of the protruding pieces 8, respectively. Here, the cutting line 9 is a cut-out groove having a predetermined depth in the thickness direction, and when the plastic cap 5 is peeled off with respect to the sleeve 4, it is pressed in the form of a one-touch can, that is, a flip-off type. The cutting portion 10 of the fixed shaft 11 serves to be easily separated from the upper surface 6 of the sleeve (4).

As shown in FIG. 1C, when the user separates the plastic cap 5 from the sleeve 4 in a flip-off fashion, the cutout portion 10 coupled to the compressed fixed shaft 11 of the plastic cap 5 is removed. The through hole 12 is formed in the inner side of the circular groove 7 formed in the upper surface 6 of the sleeve 4 to correspond to the area of. At this time, the protruding pieces 8 around the through hole 12 inwardly of the circular groove 7 serve to prevent stress deformation generated when cut by the shape. In addition, the pointed triangular cut line 9b formed in the gap 8a between the protrusions 8 causes the cutting force to be concentrated through the cutout portion 10 coupled to the fixed fixed shaft 11. The cutout portion 10 is easily cut from the cutout line 9b of the through hole 12.

However, in the vial flip-off type cap structure according to the prior art, a plurality of sharp triangular portions 8a and 10a are formed by the shape of the cutting line 9a of the cutting portion 10 and the shape of the cutting line 9b of the through hole 12. ) Is formed and, therefore, the user's finger may be damaged. In addition, there is a disadvantage in that a part of the cotton remains over the pointed triangular portion 8a when wiped with an alcohol swab around the top surface of the stopper and the through hole 12 exposed for use before disinfection.

In addition, in the vial flip-off type cap structure according to the prior art, when the user peels off the plastic cap 5, the non-horizontal bending internal space 7a and the gap 8a are circular grooves of the sleeve 4. (7) By being formed inside, it becomes difficult to rub rubbing alcohol batting uniformly.

In addition, the conventional flip-off type cap structure for vials uses a very thin thin plate (about 0.21 mm) of aluminum sleeve, so that the aluminum sleeve must form a plurality of protrusions and cutting lines of complex shape as described above. It has a manufacturing problem. That is, to form a conventional cap structure, a scoring device having a cutter that requires a high precision and is adapted to a specific shape, and ultra-precise drawing or pressing devices for forming a plurality of protrusions In order to meet the characteristics of the user, which requires a high quality, it requires a relatively finer product management, with the disadvantage that many defective products are followed. Therefore, the conventional vial sealing structure requires a high production cost, and has a problem that the product price increases.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, when a single bent portion having a circular cut line is formed in the cutout portion of the sleeve to release the plastic cap from the sleeve, It is an object of the present invention to provide a vial sealing structure having a flip-off type cap which is safe in use, easy to disinfect, and which makes sleeves easy to be flattened and horizontally formed on the sleeve.

An object of the present invention as described above is a flip-off type vial sealing structure having a cap having a circular shaft formed at the inner surface axis and a flip-off cap consisting of a sleeve which is pressed by heating by inserting the circular shaft of the cap into a coupling hole. In the circumference of the coupling hole of the sleeve, the cut portion is bent by pressing to form a single circular band-shaped bent portion, and a cut line is formed on the inner surface of the bent portion by scoring to form a cap. When the cutout portion is separated from the upper surface of the sleeve along the cutting line, the bent portion is flattened so as to be horizontal with the upper surface of the sleeve.

According to the present invention, the circular shaft of the cap, after heating and pressing, a predetermined circular recessed groove is formed in the shaft center, a support protrusion and a support edge of a semicircular cross section are formed around the circular recessed groove to insert the sleeve into the cap. It is preferable to play a role of fixing in a closed state, and at the same time, to support the cut out portion easily.

In addition, an object of the present invention is to draw the aluminum plate member of the thin plate to produce a circular container shape, to pierce the produced aluminum container to form a coupling hole in the shaft center, and to the edge of the aluminum container a predetermined height Cutting into a sleeve to form a sleeve, pressing around the coupling hole of the sleeve to form an annular groove-shaped bent portion, and forming a cutting line in the bent portion through scoring processing; Inserting the circular shaft of the cap into the hole, and molding the circular shaft of the cap into the circular recessed groove, the support protrusion and the support rim using a hot pressing press. Achieved by a method of fabricating the structure.

In the following, a preferred embodiment of a vial sealing structure with a cap of flip-off type according to the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, when the cutoff portion 41 is cut along the cutting line at the same time by the cap 50 of the flip-off type and the cap 50, the upper surface 46 is formed into a sleeve 40 which is formed flat. It is made of sealing structure.

The cap 50 has a circular cross section at the bottom of the shaft by plastic molding and has a circular shaft 51 protruding to a predetermined height. Cap 50 is the most commonly used plastic material, 'polyolefin (polyethylene + polypropylene)' and 'PVC (polyvinyl chloride), so the present invention is not limited to the material.

In addition, the sleeve 40 has a circular container shape by drawing a thin aluminum plate, and through the piercing process, the coupling hole 43 into which the circular shaft 51 can be fitted is formed on the upper surface of the sleeve 40 ( 46) It is formed on the shaft. In addition, a single bent portion 48 is formed around the coupling hole 43 in a circular band shape that is bent by the crimping process with the cut portion 41 interposed therebetween.

Here, the bending portion 48 is a simple circle, made of a relatively simple drawing or pressing tool (not shown), and a scoring tool (not shown) guided by the inner space of the bending portion 48 to form a cutting line. After easy insertion, it is possible to easily form a cutting line of a predetermined depth in the thickness portion of the thin plate.

In particular, as shown in an enlarged view in FIG. 3, the bent portion 48 of the upper sleeve surface 46 forms a cutting line 49 having a sharp groove shape on the inner bent surface. This cutting line 49 is formed continuously in the circumferential direction together with the bent portion 48. By this cutting line 49, the cut portion 41 is easily cut and serves to move the fixed end 48a of the bent portion 48 in the cutting direction, that is, upward. Therefore, the fixed end 48a of the bent portion 48 maintains the state parallel to the sleeve upper surface 46 with the separation of the cut portion 41.

The circular shaft 51 of the cap 50 is fitted into the coupling hole 43 of the sleeve 40 thus formed, and then the end of the circular shaft 51 is spread in the circumferential direction by a predetermined hot pressing press. A predetermined circular recessed groove 51c is formed in the shaft center, and the support protrusion end 51b and the support edge 51a of the semicircular cross section are formed around the circular recessed groove 51c. Therefore, since the support protrusion 51b and the support edge 51a surround a predetermined portion of the cutout portion 41, the support protrusion 51b and the support edge 51a serve to fix the sleeve 40 in the inserted state of the cap 50. At the same time, the cut portion 41 serves to support the easy separation.

The end 42 of the sleeve 40 thus fixed is not shown, but is clamped to the inlet of the capped vial bottle containing the contents.

And, when the user holds the vial bottle with one hand and peels the tip 50a of the cap 50 upward with the finger of the other hand (F), the thickness is relatively very thin inside the bent portion 48. The cutting force is concentrated at the sharp cutting line 49, so that a crack, i.e., a crack, is generated continuously, so that the cap 50 is released from the sleeve 40. As shown in FIG.

As shown in FIG. 5, the cut portion 41 fixed to the detached cap 50 is formed in a skirt shape by the support edge 51a and the support edge 51a, and at this time, the cut portion 41 The edge on the cutting line side is almost horizontal and smooth, so that the user's hand is not stuck or the user is injured.

In addition, a smooth through hole 94 corresponding to the cutout portion 41 is formed in the upper surface 46 of the sleeve 40. At this time, the fixed end 48a of the bent portion 48 near the edge of the through hole 94 with the detachment of the cut portion 41 is substantially flattened, and at the same time, the bent portion 48 also has a sleeve ( It is maintained substantially the same horizontal state as the upper surface 46 of 40).

In this case, because the stopper (not shown) and the upper surface 46 of the sleeve 40 are exposed to the outside by the separation of the cut portion 41 and the cap 50, there are almost no sharply protruding portions, Rubbing alcohol batts to disinfect them does not leave some of the batter torn and has the effect of providing a very clean cut.

In the following, a manufacturing method of a vial sealing structure having a flip-off cap of the present invention as described above will be described.

First, the operator places the aluminum plate member of the thin plate on the worktable of the drawing processing machine and places it in the mounting groove formed corresponding to the vial inlet. Thereafter, while the worktable having the operating shaft and the mounting groove of the drawing processing machine moves up and down simultaneously, the aluminum plate member of the thin plate is drawn into a circular container shape to form a predetermined space (S10).

The aluminum container shape of the drawn thin plate is pierced to form a coupling hole in the shaft center (S20).

The edge of the aluminum container shape of the thin plate thus formed is cut horizontally by a cutting process to have a predetermined height (S30).

Subsequently, an annular groove, that is, a bent portion is formed by the crimping process around the coupling hole of the sleeve, and a cutting line is formed inside the bent portion through scoring processing (S40).

Then, by inserting the circular shaft of the cap into the coupling hole of the sleeve and setting it on the hot pressing press, while operating the operating shaft up and down, the operating shaft with the heating device is pressed against the circular shaft end of the cap, and therefore, The end is spread in the circumferential direction by a predetermined hot pressing press, and then molding processing is performed in which a circular recessed groove, a support protrusion end, and a support border are formed (S50). The molded cap and sleeve are then joined together to form a part that can be clamped to the inlet of the capped vial bottle.

As described in detail above, the vial sealing structure having the flip-off cap of the present invention has a scored cutting line formed at a single structurally simple circular bent portion, so that a sleeve using a thin aluminum material can be easily manufactured. The production cost can be relatively increased, and the product price can be lowered by maximizing the production efficiency.

In addition, the vial sealing structure with the flip-off type cap of the present invention, when the cap is detached from the sleeve, the cut portion of the through-hole is almost horizontal to the upper surface of the sleeve, there is no pointed and sharp cutting portion, Safety accidents can be prevented in advance, and even when disinfecting the periphery of the through-hole and the exposed plug, there is an effect that alcohol cotton does not remain.

In addition, the vial sealing structure having the flip-off cap of the present invention is deformed by the circular axis of the cap during heat compression, so that the circular recessed groove, the support protrusion and the support rim are formed, so that the force used to cut the cap is relatively There is an additional advantage that it is very easy to use for less.

The technical idea of the vial sealing structure with the flip-off cap of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
