Description

technical field

The present invention relates to the technical field of storage containers, particularly to a bottle cap and a bottle combination structure.

Technical background

The medical bottles are storage containers for packaging or loading medicines, and they have high encapsulation requirements for bottle bodies and caps. Special drugs require special structures to store and package, e.g. B. when filling the freeze-dried products. When filling the freeze-dried products, the injection bottle must be in the open state to drain the moisture generated during the freeze-drying and sublimation of the products. After the completion of the filling, the injection bottle needs to be sealed as soon as possible to prevent various substances unsafe for the medicines from re-entering the bottle from the air. Therefore, an injection bottle combination structure is required specifically for filling the freeze-dried products.

In the bottle structure for filling the freeze-dried products disclosed in the prior art, a medicine discharge port is provided on the bottle cap body. The cover plate is connected to the bottle cap body by a connecting member. After the bottle is filled with medication, the cover plate must be inverted, the connector bent at the same time, and then the cover plate snapped at the drug dispensing port to complete the encapsulation. Since medical bottle caps are mostly injection molded products, the injection molded product itself has a certain elasticity. To avoid rebounding after bending causing the encapsulation to be loose, the bend is usually set very thin. However, due to the low low-temperature resistance of the plastic and thus its brittleness at low temperatures, it is easy to break when bent, which affects the yield.

In addition, as the value of medicines increases, counterfeiting and secondary uses often occur, which not only harms the health of patients, but also adversely affects manufacturers and hospitals. In the prior art, the appearance does not change after opening and closing the cover plate. When opening, the structure of local self-destruction and detachment at the snap connection is very small and not easy to see. Simply sticking point adhesive, the cover plate is easy to lock the second time, so it is easy to use the empty medicine bottle twice from the criminals, or steal a small amount of medicine from the dispensing port, re-capsulate the bottle and sell it , resulting in an insufficient amount of medication and a potential safety hazard.

Disclosure of Invention

Therefore, the technical problem to be solved by the present invention is that the yield of the existing bottle cap structure is low and the secondary use of the bottle cap is not easy to identify.

The technical solution of the present invention has the following advantages:

1. 1. The present invention provides a bottle cap in which the pull tab, which is integral with the self-destruct portion, is connected to the dispensing port through the self-destruct portion and covers the dispensing port, so that the dispensing port is always in the state where it is covered by the pull tab before the material is removed. Since it is not necessary to operate the pull tab for capping after filling the bottle, the pull tab is prevented from being damaged by an operating force. This improves the yield of the product. In addition, the pull tab and the self-destructing section on the removal opening are formed in one piece. When opening the removal opening, the pull tab has to be pulled and thus the self-destructing section is broken. The broken self-destructing Section cannot be repaired and is very easy to identify, avoiding the secondary use of the bottle cap and improving the safety and reliability of the bottle cap.
2. 2. The present invention provides a bottle cap in which a stopper portion is disposed below the connecting portion. During assembly, the bottle cap is fitted to the bottle mouth through the stopper portion in advance. The stopper portion is the annular portion of the bottle cap near the opening rim. The bottle cap is fitted onto the bottle mouth by the annular portion so that the top of the bottle mouth abuts the bottom of the clamp claws to reach the limit. The annular stopper section is adapted to the outer shape of the bottle opening. Thus, the stopper portion and the bottle mouth can be relatively fixed to each other without changing the structure of the bottle body. As a result, the structure is simple and the processing cost is lower.
3. 3. The present invention provides a bottle cap in which the orthographic projections of the pull tab, the connecting portion and the restricting portion do not overlap in the axial direction of the cap body. They do not affect each other in their structure, which is advantageous for processing and injection molding.
4. 4. The present invention provides a bottle cap in which a honeycomb bayonet is incorporated on the outer peripheral wall surface of the cap body, which is advantageous for batch transportation and assembling of the bottle cap and improves assembling efficiency.

Example 1

This embodiment provides a bottle cap made of plastic material as in 1 shown comprising a cap body, a pull tab 2, at least one self-defeating section, a connecting section and at least one flow-through structure. The cap body 1 is provided with a top wall having an opening 10 for taking out. In this exemplary embodiment, the removal opening 10 has the shape of a lock hole. The pull tab 2 has a shape corresponding to the shape of the removal opening 10, and the pull tab 2 has a thickness the same as the thickness of the top wall. At the same time, the upper surface and the lower surface of the pull tab 2 are flush with the outer surface and the inner surface of the top wall, respectively, which can prevent the pull tab 2 from protruding from the lower surface of the top wall, causing the gasket body (not shown in the figure 1) exerts a force on the pull tab 2, or protrudes from the top surface of the top wall, so that the pull tab 2 is pressed by external objects during assembly or transportation, resulting in damage to the pull tab 2. In this embodiment, the sealing body is a rubber stopper. The sealing body can also be a silicone plug, etc. according to specific needs.

In the radial direction, there is an equidistant gap between the side wall surface of the pull tab 2 and the top wall. The self-destructing section is located in this gap. In this embodiment, the self-destructing portion is a sheet-shaped self-destructing strip 3. The plurality of self-destructing strips 3, e.g. B. five, are distributed in the gap spaced through which the pull tab 2 is firmly connected to the top wall. In this embodiment, the pull tab 2 and the self-destructing portion 3 are integrally formed on the discharge port 10, so that the discharge port 10 is always in the state of being covered by the pull tab 2 before the material is discharged. Since it is not necessary to operate the pull tab 2 for capping after filling the bottle, the pull tab 2 is prevented from being damaged by an operating force. This improves the yield of the product. In addition, the pull tab 2 and the self-destructing section on the removal opening 10 are formed in one piece. When the removal opening 10 is opened, the pull tab 2 must be pulled and the self-destructive section is thus broken. The broken self-destruct section cannot be repaired and is very easy to identify, avoiding the secondary use of the bottle cap and improving the safety and reliability of the bottle cap.

As in 3 1, the pull tab 2 partially protrudes from the inner cavity of the cap body 1 in the radial direction of the cap body 1. As shown in FIG. Because the rubber stopper is fixed in the internal cavity of the cap body 1 and abuts the top wall of the cap body 1, the protruding part of the pull tab 2 can be located away from the rubber stopper, which makes it easier to apply the force to the pull tab when opening the dispensing opening.

As in 2 1, a connecting portion is arranged on the inner wall surface in the circumferential direction of the cap body 1. As shown in FIG. In this embodiment, the connecting section consists of a plurality of clamping claws 4. As in FIG 3 1, four clamping claws 4 are provided evenly distributed on the inner wall surface of the cap body 1. As shown in FIG. In the axial direction of the cap body 1, the clamping claws 4 are located away from the pull tab 2, which facilitates processing by mold and for molding. Each of the clamping claws 4 extends toward the inner cavity of the cap body 1 and is inclined to one side of the top wall. The clamp claw 4 is adapted to be clamped in the clamp slot at the bottle mouth of the bottle body (not shown in the figure). Here, the clamping slit is a stepped transition portion of the transition from the bottle mouth to the bottle neck, which is a bottle body structure of conventional medicinal freeze-dried products. Each of the clamping claws 4 is spaced from the opening edge of the cap body 1 to close the plug portion 40 to build. During assembly, the bottle cap is put on the bottle mouth through the stopper portion 40 in advance. The plug portion 40 is the annular portion of the cap body 1 near the opening rim. The cap body is fitted onto the bottle mouth through the annular portion so that the top end of the bottle mouth abuts the bottom of the clamp claws 4 to reach the limit. The annular stopper section 40 is adapted to the outer shape of the bottle opening. Thus, the stopper portion and the bottle mouth can be relatively fixed to each other without changing the structure of the bottle body. As a result, the structure is simple and the processing cost is lower.

As in 2 1, a restricting portion is disposed on the inner wall surface above the clamp claw 4 in the circumferential direction. In this embodiment, as in 3 shown, the orthographic projections of the pull tab 2, the pinch claw 4 and the restricting portion in the axial direction of the cap body 1 are not, that is, the restricting portion is located away from the pinch claw 4 and the pull tab 2 so that they do not affect each other in structure, which is advantageous for mold processing and injection molding. In this embodiment, the restricting portion is a projection 5. A restricting space is enclosed between the projection 5 and the top wall. The rubber stopper is fixed in this delimitation space. At this time, when the bottle cap is fitted onto the bottle mouth by the stopper portion 40, the rubber stopper is erected above the bottle mouth, leaving an air-permeable gap between the rubber stopper and the bottle mouth. Of course, the restricting portion may also be a claw-shaped structure similar to the clamping claw 4 underneath. The structure is suitable to confine the rubber stopper in the confinement space. In this embodiment, the flow structure is a flow channel 6. As in FIG 4 shown, at least one first groove 60 is introduced on the inner wall of the cap body 1 above the clamping claw 4 . The first groove 60 extends from the clamp claw 4 along the axial direction of the cap body 1 and passes through the top wall to communicate with the outside, forming a flow channel 6 . In this exemplary embodiment, four through-flow channels 6 are introduced. A first groove 60 is introduced above each of the corresponding clamping claws 4 . In the radial direction of the cap body 1, the first groove 60 is located at least partially away from the rubber stopper, that is, the maximum diameter of the circumference where the groove bottom of the first groove 60 is located is larger than the diameter of the rubber stopper to prevent that the rubber stopper blocks the first groove 60. Because the stopper portion of the rubber stopper is spaced above the clamp claw, the first groove 60 can communicate with the gap between the bottle opening and the rubber stopper to facilitate gas release when the drugs in the bottle are dried and sublimated.

As in 1 , 2 or 4 1, a honeycomb bayonet 7 is fitted to the outer peripheral wall surface of the cap body 1. As shown in FIG. The honeycomb bayonet 7 is a second groove formed on the outer wall surface of the cap body 1 in the circumferential direction. The provision of the honeycomb bayonet 7 is advantageous for batch transportation and bottle cap assembly, and improves assembly efficiency.

In this embodiment, the cap body 1, the pull tab 2, the self-destructing tab 3, the clamping claw 4, the projection 5, the first groove 60 and the honeycomb bayonet 7 are all integrally injection molded.

• Der Gummistopfen wird im Voraus im inneren Hohlraum des Kappenkörpers 1 befestigt. Der Stopfenabschnitt 40 der Flaschenkappe wird im Voraus auf die Flaschenöffnung aufgesetzt, die durch den Spalt zwischen dem Gummistopfen und dem Durchflusskanal 6 mit der Außenwelt verbunden ist. Nachdem das pharmazeutische Produkt in der Flasche durch Sublimation und Ablassen der Feuchtigkeit aus dem Spalt und dem Durchflusskanal 6 zu einem Pulver gebildet geworden ist, wird die Flaschenkappe gedrückt. Die Klemmklaue 4 legt dann an die Flaschenöffnung an, biegt in Richtung der ersten Nut 60 und gleitet nach unten, bis sie in den Klemmschlitz des Übergangs zwischen der Flaschenöffnung und dem Flaschenhals gleitet. Die Klemmklaue 4 prallt zurück und verriegelt sich im Klemmschlitz, während der Gummistopfen die Flaschenöffnung abdichtet. Dann ist die Montage abgeschlossen.

The assembling process of the bottle cap in this embodiment is as follows:

• The rubber stopper is fixed in the inner cavity of the cap body 1 in advance. The stopper portion 40 of the bottle cap is put on the bottle mouth, which communicates with the outside through the gap between the rubber stopper and the flow passage 6, in advance. After the pharmaceutical product in the bottle is formed into a powder by sublimation and draining the moisture from the gap and the flow channel 6, the bottle cap is pressed. The clamping claw 4 then rests against the bottle mouth, bends towards the first groove 60 and slides down until it slides into the clamping slot of the transition between the bottle mouth and the bottle neck. The clamp claw 4 rebounds and locks in the clamp slot while the rubber stopper seals the bottle opening. Then the assembly is complete.

As the first alternative embodiment of Embodiment 1, the flow passage 6 may also be a through hole made on the side wall between the clamp claw 4 and the restricting portion.

As the second alternative embodiment of the embodiment 1, the flow-through structure may also be a flow-through opening formed as a perforation with a width not greater than the width of the clamp claw 4, extending from the clamp claw 4 extends toward the top wall and is in the open state, which is also suitable for gas discharge without affecting the sealing.

As the third alternative embodiment of Embodiment 1, the connecting portion and the plug portion 40 can also be replaced with a female thread portion. A corresponding externally threaded section is arranged at the bottle opening. During assembly, the connecting portion can be screwed to the bottle mouth to form a half plug to ensure a gap remains between the seal body and the bottle mouth. After sublimation, the connection section is fully screwed and fixed.

As the fourth alternative embodiment of Embodiment 1, the connecting portion and the plug portion 40 may not be provided, so that the cap body below the sealing body is always in the press-fit with the bottle mouth. During assembly, the cap body is first partially fitted onto the bottle mouth to form a half plug to ensure a gap remains between the seal body and the bottle mouth. After sublimation, the cap body is fully pressed onto the bottle mouth.

Example 2

This embodiment provides a bottle combination structure including a bottle body and a bottle cap described in embodiment 1, wherein the bottle cap is fitted onto the bottle mouth of the bottle body to form an encapsulation.

Obviously, the above-mentioned embodiments are only examples for a clear description and are not intended to limit the manner of implementation. Changes or modifications in other different forms may also be made by those skilled in the art based on the above description. It is neither necessary nor possible to list all implementations exhaustively here. But the derived and obvious changes or modifications still fall within the scope of the present invention.
