Description

Vial sealing structure with a tear-off cap {STRUCTURE FOR SEALING OF VIAL WITH TEAR-OFF TYPE CAP}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vial sealing structure having a tear off type cap, and in particular, to easily check the direction of removing the cap, and to securely and easily detach the cap from the sleeve by a structural coupling relationship. A vial sealing structure having a tear-off type cap is provided.

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.

These vials may be formed for small packages such as muscle relaxants, anesthetics, antibiotics, etc., or they may be formed in medium to large sizes, such as infusions, intravenous injections, etc., especially if they contain contact lenses or special purpose reagents, Together with the sleeve, the sleeve can be completely removed from the vial bottle.

The vial 1 according to the prior art is formed of a sterile, antibacterial glass material or a plastic material that has passed a predetermined drug container test method as shown in FIG. 1, and has a vial having a space for storing contents therein ( Has 2). At the inlet 3 of the vial 2, a stopper (not shown) such as a septa is inserted into the inner diameter of a sterile, antimicrobial rubber, and Teflon (PTFE: PolyteTraFluoroEthylene) material. This vial 1 has a tear off type cap sealing structure.

Here, the tear-off type cap sealing structure is for removing the fitted plug from the vial (1), a cutting line (7) designed to allow the sleeve (5) to be detached from the inlet (3) of the vial (2) It is formed on the surface of the sleeve 5, which means that the circular fixing portion 6 of the cap 5 is coupled to the cutout portion of the sleeve 5.

That is, since the circular fixing part 6 formed in the shaft center of the cap 5 is simply inserted in the engaging hole formed in the cut-out part of the sleeve 5, and the end is crimped | bonded, the cap 5 and the sleeve 5 are ) Are combined so as not to be separated from each other.

Therefore, when the user pulls the transparent plastic cap 5 obliquely upward, an aluminum sleeve 4 clamped around the inlet 3 of the vial 1 is along the cutting line 7. It is torn and peeled off and therefore written, exposing the stopper to the outside. In this case, the stopper can be pulled out of the inlet 3 of the vial 2 by the user.

In particular, the conventional cap 5 is formed of a transparent material in order to display the cutting line 7 of the sleeve 4 or to indicate the cutting direction so that the cap 5 is easily removed together with the sleeve 4.

On the other hand, although not shown, some of the caps are made of opaque plastic materials with various colors to distinguish the types of contents of the vials 2, and thus, the entire vial vials 1 are carefully examined to confirm the cutting direction. Provides inconvenience in use that must be observed.

In order to solve this problem, the tear-off type sleeve 4 generally allows the cutting line 7 to be identified through the transparent cap 5 or intaglio direction direction 8 indicating the cutting direction on the upper surface of the sleeve 4. It is displaying. In the other case, the sleeve 4 prints a predetermined character 9 on the circumferential surface on which the user exerts a force, so that the production of the sleeve 4 becomes relatively complicated, and additional processes (printing of letters, symbols, and colors) are performed. And uneven engraving, etc., are driving up manufacturing costs.

And yet another type of cap is formed of a transparent material, such as the cap (5) described above, in order to distinguish the type of the contents of the vial (2), the whole or part of the sleeve 4 (especially the upper surface) to have a variety of colors printed The production cost is very expensive.

In addition, since the conventional tear-off type cap is fastened to the sleeve by the circular fixing part as mentioned above, it is freely rotated or slid in the circumferential direction on the upper surface of the sleeve, so that the direction intended by the user (that is, the sleeve is torn off) The direction in which the user exerts a force and the tearing direction of the sleeve often do not coincide with each other. In this case, the sleeve has a disadvantage that the cutting force is not applied along the cutting line but rather a portion that receives a relatively large cutting force, so that the cap is not easily peeled off or the sleeve is torn abnormally. This prevents the user from efficiently transmitting the force in the correct cap removal direction, so that the user who needs the relatively excessive force performs the vial opening operation inefficiently. Of course, you can design the cutting line of the sleeve so that it will tear easily even if the sleeve is pulled in a slight force and ambiguous direction, but in this case, with the difficulty of making the scoring of the cutting line on the thin sleeve, This results in the cap coming off the sleeve, which has the disadvantage that product defects may occur.

Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, the marker for indicating the position of the force applied to the cap and the fixing jaw for preventing rotation of the cap and enhancement of the bearing capacity integrally by plastic molding. It is an object of the present invention to provide a vial sealing structure having a cap of a tear-off type having a cap formed thereon, and a sleeve coupled with the cap can be smoothly removed and the manufacturing cost can be significantly reduced.

An object of the present invention as described above is a vial sealing structure having a cap having a variety of colors, a tear-off type cap consisting of a circular cut portion, a portion of the upper surface, a portion of the circumferential wall and a sleeve formed with a cutting line formed at the bent portion. In the cap, the cap has a coupling shaft formed integrally with a fixed jaw protruding from one side circumferential surface of the lower surface of the shaft, and a mark is formed at one side of the upper surface, and the sleeve forms a support groove fitted with the fixed jaw of the coupling shaft in the coupling hole. The tier is characterized in that the cap and the sleeve into which the coupling shaft is inserted into the coupling hole are not rotated by the fixing jaw and the support groove after the heat compression process, and thus, the user can accurately transmit the force in the direction desired by the user. A vial sealing structure with an off type cap is achieved.

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

The present invention has a circular cap 50 having a variety of colors to distinguish the contents of the vial by color. In addition, in the present invention, the sleeve 40 having the cutting line 70 to 73 formed on the circular cutout portion 47, the sleeve upper surface portion, the circumferential wall portion and the bending portion by scoring according to a predetermined incision design. Is provided.

In particular, the cap 50 is added to the color 'polyolefin (polyethylene + polypropylene)' and 'polyvinyl chloride (PVC), and is a plastic material that has passed the prescribed drug container test method. On the upper surface of the cap 50, a direction mark 51 in the form of an unevenness is formed, which indicates a position at which the user should apply a force in order to open the cap 50 in an eccentric position, and the user can easily identify it. . That is, the direction mark 51 is formed of a triangular protrusion 51b inside a relatively large circular or triangular groove 51a, wherein the height of the triangular protrusion 51b is the same level as the top surface of the cap 50. . Such a directional mark 51 is formed with the vertices on the imaginary line passing through the axial center of the marker and the axial center of the cap 50 facing the circumference, pointing to the user's finger contact point.

This cap 50 forms a circumferential wall of height that can cover the top of the sleeve 40 slightly. In addition, the coupling shaft 56 is formed in the lower axis of the cap 50 so as to protrude to a predetermined height. In addition, a fixing jaw 55 is formed at an edge of the cap 50 in contact with the coupling shaft 56 and the lower surface in the opposite direction to the mark 51 (see bottom view in FIG. 3A). Here, the fixing jaw 55 is a shape similar to a keyhole shape and fits into the support groove 45 of the coupling hole 46 formed in the sleeve 40, and the cap 50 on the upper surface of the sleeve 40. ) Is fixed so as not to rotate in the circumferential direction.

In particular, as shown in FIG. 2 or FIG. 3B, the first cutting line 70 formed at the cutting portion 47 of the sleeve 40 has a finite circular shape. In addition, the second cutting line 71 formed on the upper surface of the sleeve 40 is made of two, and extends horizontally in the opening direction of the cap 50 on one side of the first cutting line 70, the sleeve 40 The circular cut portion 47 and a portion of the belt-shaped upper surface of the sleeve 40 are separated from the upper surface of the sleeve 40. In addition, the third cutting line 72 extends from the second cutting line 71 toward the edge along the circumferential wall of the sleeve 40, wherein only one of the two cutting lines 72 extends to the edge end surface of the sleeve 40. Is extended. Thus, a portion of the circumferential wall of the sleeve 40 is separated from each other by a third cutting line 72 extending toward the edge when the cutting force is applied, but by the cutting line not extending to the edge. The circular cut portion 47 and the upper portion of the belt-shaped portion is not separated from the sleeve (40). Then, when the user further applies the force to the cap 50 in the horizontal direction, the sleeve 40 is based on the fourth cutting line 73 of the bent portion designed to cut only a portion of the upper surface thereof, that is, the opposite side, that is, the third By splitting the cut line 72 side, it can be easily removed with the cap 50 from the vial of vial.

As shown in FIG. 4, in the vial sealing structure having the tear-off type cap of the present invention described above, the coupling shaft 56 of the cap 50 is inserted into the coupling hole 46 of the sleeve 40. It is formed to spread in the circumferential direction by a predetermined hot pressing press.

This coupling shaft 56 has a support protrusion end 56a and a support rim 56c having a semicircular cross section about a circular recessed groove of the shaft center. The support protrusion 56a and the support rim 56c serve to support the cutout portion 47 connected to the cap to be easily separated from the upper surface of the sleeve 40. Here, the bearing force is a force generated on the upper surface of the sleeve 40 clamped to the vial when the cutting force is generated by the user. That is, when the user pulls the cap 50 obliquely upward, the pulling force is transmitted to the cutout portion 47, and thus a crack is generated at the first cutting line 70, which generates a crack. It means the force generated by repulsion to the cutting force.

In addition, a relatively thick and protruding portion 56b is formed in the peripheral portion where the fixing jaw 55 was formed, and the supporting groove 45 of the coupling hole 46 includes the fixing shaft 55 and the coupling shaft ( 56) By being partly filled, the bearing force is further generated in the direction opposite to the direction of the cutting force, and the rotation of the cap 50 is prevented.

Therefore, the user easily visually checks the direction mark 51 formed on the upper surface of the cap 50, and then applies a force to the edge of the cap 50 indicated by the direction mark 51. At this time, since the cap 50 is not rotated on the upper surface of the sleeve 40 by the above-described coupling relationship of the present invention, the force is accurately transmitted in the direction intended by the user.

In addition, since the force transmitted by the user to the cap 50 is transmitted obliquely upward, it is in the opposite direction of the bearing force of the sleeve 40 fixed to the vial vial.

Therefore, the sleeve 40 is elastically supported by a slightly thick and protruding portion 56b formed by compressing the fixing jaw 55, thereby generating stable support force, and the cutting portion 47 of the sleeve 40 is By smoothly cutting along the first cutting line 70 and simultaneously cutting along the other cutting lines, the user can safely and easily remove this sleeve 40 and cap 50 from the vial vial.

As described in detail above, since the vial sealing structure having the tear-off type cap of the present invention forms a direction marker integrally on the upper surface, the vial sealing ability is excellent, and thus the user can apply a force in the correct opening direction. Also, even when opening a plurality of vials, since the opening direction can be checked with the naked eye in advance, there is an advantage that the work efficiency can be increased.

In addition, the vial sealing structure having the tear-off type cap of the present invention couples the cap having the fixing jaw and the sleeve having the supporting groove to each other, thereby preventing shaking, slipping or rotation when applying force. Force transmission can be made accurately, and by generating a support force stably, there is an advantage that can facilitate the opening of the vial.

The technical idea of the vial sealing structure with the tear-off cap of the present invention has been described above with the accompanying drawings, but this is by way of example and not by way of limitation. 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.
