Abstract

Combined Bottle and Cap Structure The present invention relates to a combined bottle and cap structure, comprising a cap body, a tear strip, at least one self-destructing portion, and a connecting portion. The tear strip is connected to and covers a gripping orifice via the self-destructing portion. The tear strip and the self-destructing portion are formed as a single unit, so that the gripping orifice is always covered by the tear strip before material is picked up. No further operation on the tear strip is required for capping after the bottle has been properly filled, thus avoiding damage caused by stress on the tear strip and improving product yield.Since the pull tab and the self-destructing part are integrally formed at the opening, when the opening is opened, it is necessary to pull the pull tab to break the self-destructing part, which is clearly identifiable. This prevents secondary use of the bottle cap and improves its safety and reliability. Furthermore, a cap mounting section is located under the connecting part, allowing the cap to be pre-mounted to the bottle mouth. This cap mounting section is a cap ring near the edge of the mouth, which is adapted to the external shape of the mouth. Therefore, mounting and securing can be carried out without altering the structure of the bottle body, resulting in a simple design and reduced processing costs. Figure 1.

Description

Title of the invention: Combined bottle and cap structure FIELD OF INVENTION

[0001] The invention relates to the field of storage containers. More particularly, the invention relates to a combined bottle and cap structure. PRIOR TECHNOLOGY

[0002] Medical vials are storage containers used for packaging or loading medicinal products, and the requirements for the vial body and stopper are relatively high. Special medicinal products must be stored and packaged with a special structure. For example, for lyophilized bottled products, during bottling, the vial for injection must be opened so that moisture can be evaporated during the sublimation lyophilization process; moreover, once bottling is complete, the vial for injection must be closed as soon as possible to prevent any hazardous substances present in the air from entering the vial. Therefore, it is necessary to adopt a combined vial structure specifically designed for lyophilized bottled products.

[0003] According to the prior art, in the bottle structure described for canned freeze-dried products, the bottle cap body has a drug dispensing port, the cover plate is connected to the bottle cap body by a connecting piece, and the cap must be inverted once the drug is filled into the bottle. Simultaneously, the connector is bent and the cover is snapped onto the drug dispensing port to complete the packaging. Since most medical bottle caps are injection-molded products, the product itself has a certain degree of elasticity. After folding, to prevent springback, the packaging is not rigid. The folded portion is generally very thin, but the low-temperature resistance of the plastic is poor; it becomes brittle at low temperatures and is easily broken during folding, which affects yield.

[0004] Moreover, with the increasing value of medicines, counterfeiting and misuse have occurred from time to time, which not only harms patients' health but also negatively impacts manufacturers and hospitals. In the prior art, the cover plate does not change its appearance after being opened and closed. When opened, the structure of partial self-destruction and detachment at the locking loop is very subtle and difficult to detect. The cover can be easily detected. The plate is closed twice, making it easy for criminals to reuse the vial. empty medicine, or stealing a small amount of medicine from the insertion orifice, then repackaging and selling it again, resulting in insufficient quantity and potential safety hazards.

[0051] According to an embodiment illustrated in [Fig. 1], the bottle cap is made of plastic and comprises a cap body, a tear tab (2), a connecting portion, at least one self-destructing portion, and at least one circulation structure. The upper wall of the cap body (1) has a gripping orifice (10). In this embodiment, the shape of the gripping orifice (10) is of the type The keyhole, and the shape of the pull tab (2) is the same as that of the grip opening. The shape of the grip (10) matches, and the thickness of the pull tab (2) is the same as the thickness of the top wall. The upper and lower surfaces of the pull tab (2) correspond to the outer surface of the corresponding top wall. Adjust flush with the inner surface to prevent the pull tab (2) from protruding beyond the lower surface of the top wall in such a way that the sealing body (not shown in the figure) exerts force on the pull tab (2), or from protruding beyond the top wall. The upper surface of the pull tab (2) is pressed by external objects during installation or transport, causing damage to the pull tab (2).In this embodiment, the sealing body is a rubber stopper, and the sealing body can also be a silicone or similar stopper, depending on specific requirements.

[0052] In the radial direction, an equidistant space is left between the surface of the side wall and the upper wall of the tear-off tongue (2), and the self-destructing portion is disposed in this space. In this embodiment, the self-destructing portion is a self-destructing strip in the shape of a leaf (3). There are several self-destructing strips (3), such as five, distributed in the space at intervals, and the tear-off tongue (2) is fixedly connected to the upper wall. In this embodiment, the tear-off tongue (2) is integrally formed with the self-destructing strip (3) over the gripping orifice (10), so that the gripping orifice (10) is always covered by the tear-off tongue (2) before the material is used.After the bottle, it is not necessary to encapsulate the tear-off tab (2) to avoid damaging the tear-off tab (2) and improve product yield; and the tear-off tab (2) and the self-destructing part are integrally formed in the grip orifice (10), when opening the grip orifice (10), the tear-off tab (2) must be pulled to cause fracture and damage to the self-destructing part, which cannot be repaired and is easy to identify, avoiding the secondary use of bottle caps and improving the safety and reliability of the use of bottle caps.

[0053] See [Fig.3], in the radial direction of the stopper body (1), the pull tab (2) partially protrudes from the inner cavity of the stopper body (1), because the rubber stopper is fixed to the stopper body (1). In the inner cavity of the stopper body (1) and against the upper wall of the stopper body (1), the extension of the pull tab (2) avoids the rubber stopper, which is convenient for the pull tab when opening the gripping orifice.

[0054] See [Fig. 2], the inner wall of the stopper body (1) is provided with connecting pieces in the circumferential direction. In this embodiment, the connecting pieces are several prongs (4), as illustrated in [Fig. 3]. There are four prongs (4), uniformly distributed over the surface of the inner wall of the stopper body (1), in the axial direction of the stopper body (1). The prong (4) is positioned to avoid the tear-off tab (2), which is convenient for processing and shaping the mold. Each prong (4) extends into the inner cavity of the stopper body (1) and is positioned obliquely towards the side of the upper wall. The prong (4) is adapted to be clamped onto the mouth of the bottle body (not shown in the figure).In the groove, the groove in the card acts as a stepped transition piece from the bottle mouth to the neck, a conventional bottle structure for lyophilized medical products. The claw (4) and stopper body (1) are arranged at intervals, forming the stopper mounting section (40). During assembly, the stopper can be installed onto the bottle mouth through the stopper mounting section (40). The stopper mounting section (40) is the stopper body (1) near the opening. The edge portion of the ring is sleeved onto the bottle mouth through the ring, so that the upper end of the bottle mouth is against the bottom of the claw (4) to create a boundary.The cap mounting section (40) of the ring is adapted to the external shape of the bottle mouth; it can be fixed together without changing the structure of the bottle body; the structure is simple and the processing cost is lower.

[0055] See [Fig. 2], a boundary portion is provided circumferentially on the surface of the inner wall above the claw (4). In this embodiment, as shown in [Fig. 3], the pull tab (2), the claw (4), the orthographic projections along the axis of the plug body (1), and the boundary portion do not overlap; that is, the boundary portion avoids the claw (4) and the pull tab (2), and the structure does not affect it, which is convenient for mold processing by injection molding. In this embodiment, the boundary portion is a boss (5). A boundary space is enclosed between the boss (5) and the upper wall. The rubber plug is fixed in the boundary space.When the bottle stopper passes through the stopper mounting section (40), and is fixed onto the bottle mouth, the rubber stopper is erected above the bottle mouth, leaving a breathing space between the bottle mouth and the stopper. Of course, the limiting portion can also be a claw-shaped structure similar to the claw (4) below, which is adapted to confine the rubber stopper within the limiting space. In this embodiment, the circulation structure is a circulation channel (6). As shown in [Fig. 4], at least... A first housing (60) is provided on the inner wall of the plug body (1) above the claw (4). The first housing (60) extends from the claw (4) along the axial direction of the plug body (1) and penetrates the upper wall to communicate with the outside, forming a circulation channel (6). In this embodiment, four circulation channels (6) are open, corresponding to each first housing (60). A first housing (60) is positioned above the claw (4), and in the radial direction of the plug body (1), the first housing (60) at least partially avoids the rubber stopper, i.e., the circumference of the bottom of the groove of the first housing (60). The maximum diameter of the circumference of the bottom of the groove is larger than the diameter of the rubber stopper to prevent the rubber stopper from blocking the first housing (60).The rubber stopper is positioned above the claw; the first housing (60) can connect the space between the mouth of the bottle and the rubber stopper. It is convenient to release gas when the medication in the bottle has dried and sublimated.

[0056] See [Fig.1], 2 or 4, a bayonet 7 is provided on the outer peripheral wall of the stopper body (1), and the bayonet 7 is open circumferentially to the outside of the stopper body (1). The arrangement of the second housing on the wall and of the bayonet (7) facilitates bulk transport and assembly of bottle stoppers and improves assembly efficiency.

[0057] In this embodiment, the cap body (1), tear-off tab (2), self-destructing strip (3), claw (4), boss (5), first housing (60) and bayonet (7) are all integrated.

[0058] The bottle cap assembly process in this embodiment:

[0059] The rubber stopper is pre-installed and fixed in the internal cavity of the body The cap (1), the cap mounting section (40) of the bottle cap is pre-sheathed onto the bottle mouth, and the bottle mouth passes through the gap between the rubber stopper and the circulation channel (6) and is connected to the outside. Once the drug product in the bottle has sublimated, the water is expelled from the gap and the circulation channel (6) to form a powder. The bottle cap is then pressed, and the claw (4) abuts against the bottle mouth and bends towards the first housing (60) and slides downward. As it slides into the slot in the transition portion between the bottle mouth and the neck, the claw (4) rebounds and locks into the slot. Simultaneously, the rubber stopper seals the bottle mouth, and the assembly is complete.

[0060] As a first implementation variant of embodiment 1, the circulation channel (6) can also be a through hole open on the side wall between the claw (4) and the limiting portion.

[0061] As a second variant of the embodiment (1), the circulation structure can also be a circulation orifice, extending from the claw (4) towards the upper wall to open a space not greater than the width of the claw (4), in an open state, similarly it is convenient for the discharge of gas and does not affect the sealing.

[0062] As a third embodiment of the design (1), the connecting portion and the cap mounting section (40) can also be replaced by internal thread segments, and the bottle mouth is provided with a corresponding external thread segment. During installation, the connecting portion can be partially screwed onto the bottle mouth to form a half-cap, ensuring a gap between the sealing body and the bottle mouth. Once sublimation is complete, the connecting portion is fully screwed in and tightened.

[0063] As a fourth embodiment of embodiment 1, the connecting portion and the cap mounting section (40) may be omitted, so that the cap body under the sealing body and the bottle mouth are always tightly fitted. The cap is partially sheathed and fitted onto the bottle mouth to form a half-cap to ensure a gap between the sealing body and the bottle mouth. Once sublimation is complete, the cap body is fully pressed and fitted onto the bottle mouth. Implementation method 2

[0064] This embodiment provides a bottle assembly structure, comprising a bottle body and the bottle cap described in embodiment 1, and the bottle cap is sleeved and fixed onto the mouth of the bottle body to form a package.

[0065] Obviously, the preceding embodiments are merely examples for clarity and are not intended to limit the possible implementations. For those skilled in the art, other changes or modifications in various forms can be made based on the above description. It is unnecessary and impossible to list all the implementation methods here. The obvious changes or modifications that result from this remain within the scope of the protection afforded by the present invention.
