Abstract

A vial capping structure having a simple sleeve configuration is provided to help users, except for children, easily release a cap and a sleeve at once so that they are not hurt by any remaining metal piece. A vial capping structure comprises a cap(40) whose protrusion portion is inserted, by compressive processing, into a through hole(51) in a sleeve(50) to form a fixed portion(43) as primary sealing, and recesses(54) are upwardly twisted to form a compressive portion(55) as secondary sealing. Also, both the cap and the sleeve are bent by a bent portion(41)/bent region(53) to enable the cap to be clamped to an opening portion(20). The sealing state between the cap and the sleeve is essential for safe decapping of a cover(30).

Description

Vial sealing structure reinforced with stability {STRUCTURE REINFORCING STABILITY FOR SEALING OF VIAL}

The present invention is a sealed structure of a vial reinforced with stability, in which the cap and sleeve constituting the cover can be flipped off at the same time, and can be flipped off at any portion without an open indication, and the ease of use of the child can be easily opened. It relates to a sealing structure of a vial reinforced with stability that can be ensured at the same time to ensure stability.

In general, a vial means a vial or a container for keeping an internal storage material such as a contact lens and other chemical liquids, such as a contact lens and a sterilized state. Since the cover is covered to maintain a sterile state, it is important to be configured to prevent the deterioration of chemicals and the like before use, and to ensure the sealing state so as not to leak out during transportation, and to ensure the convenience of opening.

The cover, which seals the upper opening of a typical vial, consists of a cap and a sleeve.

The cap (cap) is made of synthetic resin to form the upper layer of the cover, the sleeve (sleeve) is made of metal to form the lower layer of the cover, both by the coupling portion extending downward from the central portion of the cap It is fixedly coupled to each other.

The cap is mainly composed of the outside of the cover, and if the cover is made of a thin metal sleeve without the cap, it is difficult to directly peel off the sleeve itself. Sleeve opening function and double sealing guarantee function to smooth the sleeve from peeling off, and the sleeve is able to completely seal the opening of the vial as compared with the resin material having relatively low malleability or ductility, Compared to synthetic resin material, it provides tougher properties for sterilization. By virtue of the inherent characteristics and properties of the cap and sleeve, the cover of the vial consists of a coupling structure of the cap and the sleeve.

The vial sealing structure of the cover having such a structure is not an accurate classification, but is usually divided into a tear off type and a flip off type.

The tear-off type has a structure that can open the cover by forming an incision line in a certain direction of the sleeve and exerting a mark on the upper surface of the cap in one direction to tear off the incision portion of the sleeve together with the cap. And the flip-off is made so that the cap is peeled off the sleeve and the incision portion of the inner portion of the sleeve is cut to secure the opening of the vial.

By the way, the general tear-off type cover is torn only in a certain direction, when the force is shifted from side to side when tearing, it is not torn in the direction to tear, but torn in the wrong direction to form a sharp area around the torn injury to the user's hand There is a problem that can give, and the direction of tearing is limited, the use of the visually impaired is inevitably uncomfortable, and if the sticker for marking the standard on the surface of the cap is attached separately, the direction of tearing is difficult to see because it is difficult to use There is a problem.

Referring to Korean Patent Application No. 10-2006-0060323, a plurality of cutting lines and perforations are formed at a predetermined angle radially with respect to the center of the sleeve, so that the cap and the sleeve can be peeled off without direction. However, if the cutting line is too long, the stability of the seal cannot be pursued. On the contrary, if the cutting line is too short, it is easy to break at the middle part, and in principle, the force exerting force through the cap is torn. At the beginning, the opposing side should guarantee the robustness to support the force like the center point of the lever, but since the cutting line is formed radially, it does not act as the center point of the lever and is torn or the force is dispersed and starts to tear. In addition to the periphery there is a serious technical problem that can be incision. In addition, the torn portion generates atypical sharp portions and inhibits stability.

A vial sealing structure having a flip off type cover is well known in Korean Patent Registration No. 0437911.

The flip off type is also similar to the tear off type in that a portion of the sleeve is torn apart, but the cap is peeled off so that a central portion of the sleeve coupled to the center portion of the cap is cut in order to secure the opening of the vial opening. It is different from the tear-off type in that one side does not tear long.

This flip-off type is more stable than the tear-off type in that it does not leave a long, irregularly stretched cutout portion, but it can also ensure safety properly because it leaves a fine but sharply protruding cutout portion in the inner diameter portion of the cut sleeve. Had the problem.

In order to prevent such a problem, Korean Patent Registration No. 0437911 says that the cutting part is almost horizontal with the upper surface of the sleeve, thereby ensuring safety without a sharp cutting part, but the entire sleeve is peeled off the opening of the vial. Since the sleeve remains in the opening part, no matter how smooth the incision of the sleeve may be, since the sleeve has a sharp structure at the side due to its own characteristic of the thin film structure, the body is perpendicular to the sleeve surface. Except when the part touches it has the disadvantage that it holds the risk of damaging the user's body as it is.

Therefore, the vial sealing structure having a novel cover structure with a structure that can be easily peeled off by the risk that the cap and the sleeve can be safely peeled off and the chemicals stored therein while maintaining the convenience of the opening. There is a need to present a manufacturing method.

The present invention has been made to overcome the problems of the above technology, when the open external force acts on the vial, the cap and the sleeve constituting the cover is peeled off entirely, so that the user is wound by the remaining incision of the sleeve made of metal Its main purpose is to avoid receiving it.

 Another object of the present invention is to provide a cover structure that can be conveniently opened without getting in a specific direction, and at the same time to provide a cover structure that complies with the KFDA safety regulations while ensuring safety that children can not easily open .

Yet another object of the present invention is to simplify the structure of the sleeve while having the above object, thereby reducing the manufacturing process and manufacturing cost.

In order to achieve the above object, the stability reinforcing vial sealing structure according to the present invention is a structure in which the stability is reinforced by a cover for sealing the opening of the vial, the cover is provided with a protrusion protruding below the central portion, The protrusion is coupled to the sleeve and then converted into a fixed portion that is in close contact with the contact portion of the sleeve by pressing; Comprising a through hole for accommodating the projecting portion in the central portion, the sleeve is formed with a predetermined depth recessed 8 to 12 cutting lines at a predetermined angle along the circumference, consisting of the bent portion around the cap and sleeve Thereafter, the circumference of the sleeve having the cutting line formed therein is clamped around the opening to seal the opening, and when the user applies a predetermined pressure to the cover, the cap and the sleeve are coupled to each other around the cutting line. It is characterized in that the cover is opened at the opening by cracking.

In addition, the cutting line has an extension length of 0.08 to 0.12% based on the radius of the sleeve, and the thickness of the sleeve to the length of the insertion of the cutting line is 3: 2.

In addition, the outer periphery of the through hole is formed in the recess recessed to a predetermined depth, and after being coupled to the cap is provided with a plurality of compression parts protruding in the cap direction by applying pressure to the recess at a predetermined interval Characterized in that.

According to the sealing structure of the vial reinforced with the stability according to the present invention,

1) The cover can be opened through any direction without directivity, so that the visually impaired can use it conveniently.

2) When both the cap and the sleeve are peeled off when opening, the sharp cutting part of the sleeve does not remain in the vial opening portion, thereby protecting the user's body.

3) easy to use, not only can simplify or reduce the production process and production costs,

4) According to KFDA's safety regulations, only adults can use it, and children can't open it easily.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

1 is a perspective view schematically showing the overall configuration of a vial according to the present invention.

The vial 10 according to the present invention is provided with an open portion 20 at the top like a known vial, the open portion 20 is configured such that the upper end is stepped like a spout cover 30 The cover 30 is sealed in such a manner that the end of the cover is wrapped.

The cover 30 is composed of a cap 40 forming an upper configuration and a sleeve 50 forming a lower configuration, such as a known cover, and the cap 40 and the sleeve 50 are respectively directed toward the opening 20. The end is bent and the material of the cap 40 and the sleeve 50 is similar to the known cap / sleeve material, so a separate description thereof will be omitted.

Figure 2a is a plan view showing the structure of the cap constituting one configuration of the cover in the sealing structure of the vial reinforced with stability according to the present invention, Figure 2b is a perspective view of a state before the cap according to Figure 2a is coupled with the sleeve.

As can be seen from Figures 2a and 2b, the cap 40 according to the present invention has a circular shape when viewed in plan like the known cap, the circumferential portion is provided with a bent portion 41 is bent downward Doing.

2B, the center part of the back surface (inner plane) of the cap 40 is provided with the protrusion part 42 extended a predetermined length downward.

The protrusion 42 has a premise function for forming a coupling with the sleeve 50, which will be described later. The through hole 51 formed in the center portion of the sleeve 50 and the protrusion 42 are bonded to each other and then compressed. It is pressed to a portion of the sleeve 50 around the through, but the adhesive is pressed to the surface of the sleeve rather than the protruding shape so as to have a substantially planar shape, the fixing portion 43, that is, the protrusion 42 is By the fixing portion 43 is processed.

Referring to FIG. 2A, various phrases may be displayed on the upper surface of the cap 40, in particular, since the cap 40 according to the present invention does not have a direction according to the opening, 'FREE TAKE OFF' It is more preferable to mark CAP ', but it is not necessarily limited to such a phrase and may not insert the phrase itself or attach a separate sticker.

Figure 3 is a plan view and a cross-sectional view showing a state before the sleeve is coupled to the cap according to the present invention.

Referring to FIG. 3, the sleeve 50 according to the present invention is provided with a through hole 51 for engagement with the protrusion 41 of the cap 40, like the known sleeve. It can be seen that a plurality of cutting lines 52 are radially formed at a predetermined length inwardly.

The cutting line 52 is configured to have a radial structure at a predetermined angular ratio in the number of a plurality, particularly preferably 6 to 12 (more preferably, 8 to 12), and the cutting line 52 The extension length has a length of about 8 to 12% of the radius of the sleeve 50. In FIG. 3, the number of cutting lines 52 is 12, the radius of the sleeve 50 is 16.5 mm, and the cutting line has a length of 1.5 mm.

In addition, it is preferable that ratio of the depth of depression in which the cutting line 52 was formed and the total height (thickness) of the sleeve 50 is 2: 3.

The sleeve 50 has a bent portion 53 corresponding to the bent portion 41 of the cap 40 so that the sleeve 50 is wrapped around the open portion 20 by the bent portion, specifically, the open portion 20. The lower end of the bent portion is processed by the clamping treatment of the circumferential portion of the sleeve 50 on the step 20a formed at the lower side.

Among the circumferences of the clamped sleeve 50 without the cap 40 and the sleeve 50 being separated by the coupling force with the sleeve 50 by the fixing portion 43 when the user opens the cover 40. Only the part subjected to the force has a certain crack so that the cover 30 is separated from the opening part 20 by the crack part generation. Thus, when a certain force is applied to the end of the sleeve 50, a crack is generated for the release part. It is the cutting line 52 to do.

In other words, as the force applied to the user to remove the cover 30 extends to the cutting line 52, cracks or dents are generated around the cutting line 52, so that the cover 30 is separated from the opening 20. To be.

In addition, the portion of the cutting line 52, which is formed on the opposite side of the portion to which the force is applied, on the contrary, the crack is promoted so that the sleeve 50 is easily peeled off the opening 20, and the force is applied. At the same time, the force must be concentrated at the point where the crack is promoted, such as the center point in the lever, and the physical structure and arrangement of the cutting line 52 must be secured so that the crack does not occur by itself.

In other words, the inventors of the present invention have various methods regarding the physical structure and arrangement of the cutting line 52 so that the detachment of the sleeve 50 can be started only at the portion of the force acting to remove the cover 30 from the opening 20. As a result, the number of cutting lines 52 is 8 to 12 and the extension length of the cutting lines 52 has 9 to 12% based on the radius of the sleeve 50 and at the same time, the depth of cutting line: the height of the cutting line = 2: 3 'was found to be the most optimal.

In addition, a recess 54 is formed at an inner circumferential portion of the sleeve 50 at a predetermined distance from the circumference of the through hole 51. have.

The recess 54 is a means for increasing the coupling fixation force between the cap 40 and the sleeve 50. The protrusion 50 and the cap 50 are converted into the fixing part 43 by the compression processing once. Although strong adhesion occurs between the 40), the recess 54 is formed as a part to further reinforce the adhesion, that is, a plurality of portions having a predetermined interval / angle along the periphery of the recess 54. As a result of the pressing process toward the upper direction, the recessed portion 54, which receives the pressing force as a result, forms a pressing portion 55 which protrudes convexly in the upper direction, and as a result, the sleeve 50 is formed by the pressing portion 55. Is in direct contact with the cap 40.

That is, the recess 54 is a downward directional space secured to form the crimping portion 55, thereby ensuring the secondary close coupling force of the cap / sleeve.

Figure 4 is a view showing a coupling structure of the cap and the sleeve according to the present invention, Figure 4a is a cross-sectional view showing a state in which the cap and the sleeve before the compression, Figure 4b after the cap and the sleeve is compressed It is a perspective view which shows the state of.

As can be seen in FIG. 4A, the protrusion 42 of the cap 40 engages the through hole 51 of the sleeve 50 and the cap 40 and the sleeve 50 both bend 41 / bend. It has a state that is bent by the portion 53 has a state to be clamped to the opening 20.

Referring to FIG. 4B, the protruding portion 42 of the cap 40 is pressed into the periphery of the through hole 51 by the crimping process, thereby forming the fixing portion 43, and the primary close contact between the cap 40 and the sleeve 50. In addition, by pressing the upward pressure to a plurality of predetermined portions of the recess 54, the pressing portion 55 is provided with a pressing portion 55 which is crushed in the upward direction (the direction in which the cap is located). It can be seen that 55 is provided to provide a secondary close contact between the cap 40 and the sleeve 50.

Maintaining the close contact state of the cap 40 and the sleeve 50 in the present invention is a prerequisite that must be made in order to achieve a safe separation of the cover 30, the configuration described for providing adhesion is an essential configuration of the present invention This can be called.

Figure 4c shows a state that the rubber stopper is configured separately under the sleeve.

Rubber stopper 60 serves as a buffer to reduce the friction force generated between the cover 30 and the opening 20, the rubber stopper 20 is the same or slightly smaller than the diameter of the sleeve 50 It is located in the sleeve 50, the end of the sleeve 50 is clamped around the opening 20, the lower end is tightened, so that it is securely fixed inside the sleeve 50 without worry of departure.

5 is an exemplary view showing a state in which the cover according to the present invention is peeled off the vial.

As can be seen from Figure 5, the user holds the vial 10 body with one hand and the cover 30 with the other hand to apply a force. Preferably, the thumb is applied to act like a thumb to bounce one side of the cover 30, in this process the force is concentrated on the lower end of the clamped sleeve (50).

As described above, the cover 30 according to the present invention uses a principle of being pushed or broken to a weak side when a certain pressure is applied to an object. The weak side of the sleeve 50 is a position where a cutting line 52 is formed. Becomes

That is, as the corresponding end of the sleeve 50 positioned around the cutting line 52 near the applied force portion is bent, a gap is generated between the opening 20 and the sleeve 50, and in order to generate such a gap, Since the force is concentrated, the force necessary for the crack is not transmitted to the portion of the cutting line 52 of the opposite end to which the force is applied.

That is, the opposite end of the force cut line 52 acts as a center point of the lever and is held unaffected by the force (i.e., no cracking occurs), and then the sleeve 50 is peeled off from the applied area. Finally, the separation of the cover 30 is completed in such a way that the separation from the opening 20 is completed.

At this time, since the fixing portion 43 to the crimping portion 55 is designed such that the coupling force between the sleeve 50 and the cap 40 is greater than the applied force, the sleeve 50 and the cap 40 are concluded. They are separated from each other without being separated from each other.

Due to this, not only is there any piece of sleeve 50 left around the opening 20 of the vial from which the cover 30 has been removed, but also an unstable tear portion of the sleeve 50 is removed during the separation of the cap 40 and the sleeve 50. Since a clean state is not generated, problems such as physical damage do not occur at all.
