Description
Technical Field
The present invention relates to the field of containers which can be used to contain any liquid such as eye drops, cleaning fluids, nursing fluids, etc.
Background
An ampoule bottle is a common container for storing a liquid medicine, and is generally made of glass or plastic. For the ampoule bottle made of glass, in order to extract liquid medicine, medical staff needs to scratch the bottle neck by a grinding wheel and then apply pressure to break the bottle neck, so that a medicine taking opening can be formed in the bottle neck. Since medical staff are required to open hundreds of glass ampules every day, fingers are often easily scratched by the ampules as fatigue increases. According to the report of the professional medical research and research institution, 26% of the accidents that hospital medical staff are scratched by a sharp object are caused by opening the ampoule medicine bottle, and 54% of the accidents that medical anesthetists are involved in are caused by breaking the ampoule medicine bottle. The result of the medical staff's finger being scratched is not negligible. The finger scratch easily causes serious cross infection of blood-borne pathogens, even infection of high-risk viruses such as hepatitis virus, Human Immunodeficiency Virus (HIV) and the like. In addition, in the process of opening the glass ampoule bottle each time, the liquid medicine can be polluted by the invisible glass of human eyes and fragments of the grinding wheel, so that the health of a patient can be directly influenced after the injection is carried out on the patient.
Ampoules made of plastic are increasingly used because they eliminate the above drawbacks. Ampoules made of plastic generally consist of a bottle body and a cap. Plastic type ampoules are typically made by a blow fill and seal all in one machine (BSF). In the preparation process, firstly, two half bottle bodies are rolled out by a rolling die, then the axial wall surfaces of the two half bottle bodies are heated, the two half bottle bodies are folded and reinforced, then the liquid medicine is injected into the bottle bodies, and finally, the lower end surface of the bottle cap and the upper end surface of the bottle body are heated and are butted and adhered to each other, so that the injection packaging is completed. In another preparation process, a bottle body is formed by blow molding, then liquid medicine is injected into the bottle body, and finally the lower end face of the bottle cap and the upper end face of the bottle body are heated and butted and adhered to finish injection packaging.
In the blow-fill-seal machine, in any of the above-mentioned manufacturing processes, all the portions butted against each other (at least the portions of the bottle body and the bottle cap butted against each other) are heat-sealed. The port forms a flowable slurry upon being heated. During the butt joint of the butt joint part, the slurry substances inevitably flow to positions other than the butt joint surface. In particular, when the inner diameter of the thin-walled portion of the ampoule bottle is set to be small, the inner passage of the thin-walled portion is extremely easily blocked by the slurry material after the bottle cap is butted to the bottle body as described above, resulting in a manufacturing failure.
Thus, there is a need to modify existing containers to avoid manufacturing failures.

Detailed Description
The inventive concept will be described in detail below with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention. In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "transverse", etc., are used with reference to the directions as illustrated in the accompanying drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.
For convenience of explanation, in the following description of the present invention, "longitudinal" and "longitudinal" correspond to the height direction of the container; "transverse" and "transverse" correspond to a vertical direction perpendicular to the longitudinal direction of the container. "up" corresponds to the upward direction of the longitudinal direction; correspondingly, "lower" corresponds to a downward direction of the longitudinal direction.
Referring to fig. 1, 2, wherein fig. 1 shows a perspective view of a container 1 according to a preferred embodiment of the present invention. In the present invention, the container 1 includes a main body 10 and a cap 20. The main body 10 and the cap 20 form a thin-walled region 30 at a position where they are butted against each other.
The main body 10 includes a body portion 11 at a lower portion and a neck portion 12 at an upper portion. The lower body part 11 serves as a reservoir for the liquid medicament and can be designed generally cylindrical as shown in fig. 1 and 2. In addition, the bottle body can be made into a cylindrical structure with an oval cross section. The body portion 11 may be designed in other suitable shapes for aesthetic reasons. The shape of the body portion 11 can be arbitrarily set.
The mouth portion 12 located above the body portion 11 includes a lower mouth region 12B and an upper mouth region 12A. The lower bottleneck region 12B has a truncated cone shape. It should be noted that the lower bottleneck region 12B having a truncated cone-shaped configuration does not merely indicate that the lower bottleneck region 12B has only a single linear generatrix. In fact, as shown in fig. 1 and 2, the generatrix of the lower mouth region 12B consists of two straight lines at an oblique angle to the central axis and one straight line parallel to the central axis. Wherein the straight line segment parallel to the central axis has a smaller size. As for the lower bottleneck region 12B of this form, it is also "circular truncated cone" as a whole, and therefore it belongs to the "circular truncated cone" lower bottleneck region 12B which the utility model seeks to protect. In addition, have the lower bottleneck district 12B of the generating line that more straightways, slash section are constituteed, satisfying under the condition that its appearance is the taper on the whole, this kind of lower bottleneck district 12B all belongs to the utility model discloses the lower bottleneck district 12B of "round platform shape" that strives for the protection.
Inner passageway P2 of lower finish area 12B includes a cross-sectional area selected from 0.5mm 2 -3mm 2 Section S of any desired value of range, e.g. 1mm 2 、2mm 2 And the like. The minimum small-diameter section S having a small size ensures that the medicament in the container 1 flows out in a fine jet. In particular, when the container 1 is used to contain a cleaning solution for cleaning contact lenses, a physiological saline solution, or other chemical solution, a user can easily clean the contact lenses by lightly pressing the main bottle body 10 to form a small jet of the chemical solution and then injecting the jet.
Referring generally to the enlarged cross-sectional view of portion U of FIG. 2 shown in FIGS. 3A and 3B, internal passageway P2 of lower finish area 12B may be designed to have a circular cross-section; the longitudinal cross-section of internal passageway P2 is tapered to correspond to the outer "frusto-conical" shape of lower finish area 12B. In this case, the lower finish area 12B has walls of equal thickness. In the above-mentioned minimum caliber section S, the diameter of the internal passage of the lower mouth region 12B may be set at any value in the range of 0.8mm to 2mm, for example, 1mm, 1.2mm, etc.
With continued reference to fig. 3A, 3B, the cross-sectional area of the internal passageway P1, P1' of the upper finish area 12A is greater than the cross-sectional area of the smallest caliber segment S. Specifically, the cross-sectional area of the upper mouth region 12A is set to be selected from 4mm 2 -20mm 2 At any value within the range, e.g. 5mm 2 、10mm2、 15mm 2 。
Alternatively, the internal passage P1 of the upper mouth region 12A may be formed in a cylindrical shape as shown in fig. 3A, or in a truncated cone shape as shown in fig. 3B. For the internal passage P1 having the upper mouth region 12A of a cylindrical shape, the diameter of the cylinder can be set at an arbitrary value within the range of 2-5 mm.
For the internal passage 12B of the upper finish area 12A of a truncated cone shape with a smaller sized bottom surface adjoining the lower finish area 12B and a larger sized bottom surface facing away from the lower finish area 12B.
Advantageously, in the upper mouth region 12A having the larger-sized inner passage P1, when the upper mouth region 12A and the bottle cap 20 are heat-sealed and coupled to each other, a small amount of slurry material overflowing from the coupling surfaces does not block the inner passages P1, P2 (specifically, the minimum caliber section S). The design can ensure that the minimum caliber section S of the lower bottleneck area 12B is the minimum caliber section S of the whole bottleneck part 12 at the same time, thereby ensuring that the liquid medicine can be sprayed out in a trickle mode.
According to some preferred embodiments of the present invention, the minimum caliber section S of the lower bottleneck region 12B is set at the top of the lower bottleneck region 12B. This is particularly useful in the process of making the main body 10 by heat sealing two halves of the body. Specifically, when the blow-filling and sealing device heat-seals two half-and-half bottle bodies, the blow-filling and sealing device can be provided with an ejector pin with the same size as the minimum caliber section S at a position corresponding to the minimum caliber section S. When the half bottle bodies are pressed to the opposite side for butt joint, the section S with the smallest caliber is limited and formed by the ejector pin. This avoids the slurry blocking the section S of lowest diameter when the halves are pressed towards each other for docking.
With continued reference to fig. 1 and 2, optionally, a plate-shaped reinforcing rib 12C is provided on the outer surface of the lower mouth region 12B. Reinforcing ribs 12C may be formed at laterally opposite ends of the main bottle body 10 as shown in fig. 1 and 2. Further, the number of the reinforcing ribs 12C may be set to 1, 3 or more.
As for the reinforcing rib 12C, it is preferable that the top face of the reinforcing rib 12C is in contact with the bottom face of the upper mouth region 12A, and the contact region 22 region extends from the inner side to the outer side of the bottom face. Further, the top surface of the reinforcing rib 12C is designed to be in at least partial contact with the outer side surface of the upper mouth region 12A. Thus, the reinforcing rib 12C has a large contact area with the upper mouth region 12A. The container 1 is more prone to fracture in the thin wall region 30 than in the finish portion 12 when the user twists the closure 20.
The cap 20 of the container 1 is preferably provided as a plate-like member to facilitate the user to twist the cap 20 during use. The bottle cap 20 may be arranged to extend in the same direction as the reinforcing rib 12C, i.e., in a parallel manner. Referring to fig. 1 and 2, the laterally outer side of the bottom of the bottle cap 20 is preferably provided with a downwardly extending projection 21. In the longitudinal direction, the projection 21 extends at least to the thin-walled region 30.
As a preferred embodiment, the vertical cross section of the outer wall surface of the upper mouth region 12A is set to be generally semicircular as shown in fig. 1 and 2. The outer surface of the upper mouth region 12A and the reinforcing ribs 12C can form a large contact surface.
The bottle cap 20 is formed as a contact area 22 at the region where it connects to the upper mouth. The vertical cross section of the outer wall surface of the contact region 22 may be set to be generally semicircular, similarly to the outer wall surface of the upper mouth region 12A described above.
With continued reference to fig. 1 and 2, in some preferred embodiments, the longitudinal height of the upper finish area 12A is preferably set to any value selected from the range of 0.8mm to 5 mm. More preferably, it is set to select any value within 1mm-3mm, for example 2mm, 2.5 mm. In the case where a user squeezes the main bottle body 10, the liquid in the main bottle body 10 is directly discharged from the minimum caliber section S at the top of the lower mouth region 12B without contacting the upper mouth region 12A. Thus, the jet size of the vessel 1 will be directly determined by the diameter of the section S of minimum caliber. Obviously, such a smaller jet may make it more convenient for the user to clean the contact lens.
The scope of protection of the present invention is limited only by the claims. Persons of ordinary skill in the art will readily appreciate, given the benefit of the teachings of the present invention, that alternative structures to those of the disclosed structures may be implemented as viable alternative embodiments, and that embodiments of the disclosed structures may be combined to create new embodiments, which likewise fall within the scope of the appended claims.
