Abstract
The present disclosure relates to a press-fit type plastic container including a main bottle body and a bottle cap. The main bottle body is provided with a pressing surface extending along the longitudinal direction, and the main bottle body is formed by pressing two half bottle bodies along the pressing surface. The size of the bottle mouth at the upper side of the main bottle body at any position on the longitudinal section of the press-fit surface is not less than 1.2mm, and the minimum cross-sectional area of the bottle mouth is selected from 0.5mm 2 ‑3mm 2 Any value within the range. The bottle cap is connected to the bottle mouth and forms a thin-walled area at portions contacting each other. With the plastic container of the above form, the two body halves for forming the main body are heat-sealed while being butted against each otherEven if the slurry material partially flows into the inner side of the main bottle body, the opening is not sealed, thereby ensuring that the plastic container can be prepared and processed by the existing preparation machine. In addition, the smaller size of the minimum-diameter section facilitates the formation of a fine jet.
Description
Technical Field
The present disclosure relates to the field of collapsible plastic containers that can be used to contain any liquid, such as eye drops, cleaning fluids, treatment fluids, and the like.
Background
An ampoule is a common plastic 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.
Since ampoules made of plastic eliminate the above-mentioned drawbacks, their use is increasing. 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 integrated machine for blow-fill-seal, all the portions butted against each other (at least the portions butted against each other on the bottle body and the bottle cap) are heat-sealed in any of the above-mentioned preparation processes. The port forms a flowable slurry upon being heated. During the butt joint of the butt joint portion, the slurry substance inevitably flows to a position other than the press-fit 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 in the above-mentioned method, resulting in a preparation failure.
Therefore, there is a need to modify existing plastic containers to avoid manufacturing failures.

Detailed Description
The disclosed concept of the present disclosure will be described in detail below with reference to the accompanying drawings. Only the preferred embodiments according to the present disclosure are described herein, and other ways of implementing the present disclosure, which also fall within the scope of the present disclosure, may be conceived by those skilled in the art on the basis of the preferred embodiments. In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "lateral", and the like, are used with reference to the orientation depicted in the accompanying drawings. The components of embodiments of the present disclosure 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 disclosure, "longitudinal" and "longitudinal" correspond to a height direction of the plastic container; "transverse" and "transverse" correspond to a vertical direction perpendicular to the longitudinal direction of the plastic 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 and 2, there are shown a perspective view and a front view, respectively, of a press-fit plastic container 100 according to a preferred embodiment of the present disclosure. In the present disclosure, the press-fit type plastic container 100 includes a main bottle body 10 and a bottle cap 20. The main body 10 and the cap 20 are coupled and fixed to each other by the thin wall region 30. In use, the cap 20 at the top of the main bottle body 10 is released by the consumer breaking the thin wall region 30 by rotating the cap 20, and leaks out of the opening of the main bottle body 10. The consumer can then press the main bottle body 10 to spray the liquid in the main bottle body 10 in a trickle manner, thereby facilitating the cleaning of small-sized articles such as contact lenses by the consumer.
With continued reference to fig. 1 and 2, the main body 10 is formed by pressing two halves of the body against each other along a pressing surface (see dashed line B-B in fig. 3). Referring to the sectional view taken along the direction a-a of fig. 2 shown in fig. 3, the dimension L of the mouth 12 of the main body 10 at any position on the longitudinal section of the crimping plane B-B is not less than 1.2 mm. When the two body halves are pressed against each other along the press-fit plane B-B, since the inside dimension of the mouth 12 corresponding to the press-fit plane of the main body 10 is relatively large, even if some of the pasty substance flows toward the inside of the main body 10, the mouth 12 is not closed by the pasty substance.
The main body 10, which is formed to serve as a liquid storage region for containing a liquid medicine, is generally composed of a lower cylindrical portion 11 and an upper frustoconical portion 12 (a mouth 12). Alternatively, the lower cylindrical portion 11 may also be made in a cylindrical configuration with an elliptical cross-section. The lower cylindrical portion 11 may also be designed in other suitable shapes for aesthetic reasons. The lower cylindrical portion 11 may be arbitrarily replaced with other shapes.
To ensure a thin flow of fluid from the mouth 12, the minimum cross-sectional area of the mouth 12 is set at 0.5mm 2 -3mm 2 Any value within the range, e.g. 1mm 2 、2mm 2 And the like. The minimum cross-sectional area of the mouth 12 may be set according to the use habit of the consumer.
Referring to fig. 1 and 2, a bottle cap 20 of a plastic container 100 has a plate shape and is connected to a bottle mouth 12 through a thin wall portion 30. Generally, the thin-walled area 30 has any value in the range of 0.06mm to 0.6mm, such as 0.1mm, 0.2mm, etc., depending on the composition of the plastic material.
In some preferred embodiments, the main body 10 is provided with ribs 13 on the outer wall surface of the mouth 12 on the press-fit surface of the plastic container 100. Obviously, the provision of the rib 13 helps to improve the strength of the main body 10 at the position of the mouth 12, and prevents the small-sized mouth 12 from being cracked by unexpected external bending or the like.
The ribs 13 are preferably arranged to extend longitudinally to the bottom of the closure 20 to provide enhanced rigidity support in all areas of the mouth 12 that are susceptible to bending.
After the rib 13 is set to extend to the bottom of the bottle cap 20, a section 12A having a minimum cross-sectional area may be alternatively set as a narrow mouth section 12A located at the top of the main bottle body 10. The narrow-mouth portion 12A is disposed near the outlet of the main bottle 10, so that the thin stream sprayed from the main bottle 10 is thinner after the main bottle 10 is squeezed by the consumer.
It should be understood that the above-described arrangement in which the section 12A of minimum cross-sectional area is disposed adjacent the top of the main bottle 10 may be a less preferred arrangement of the present disclosure.
Will be in some preferred embodimentsIn this way, the container is provided with a wide mouth section 12B on the upper side of the narrow mouth section 12A, the cross-sectional area of the wide mouth section 12B being taken at 4mm 2 -20mm 2 Any value within the range, e.g. 5mm 2 、10mm 2 、15mm 2 And so on. With the wide mouth section 12B having a large size, when the wide mouth section 12B and the cap 20 are heat-sealed to each other, a small amount of slurry material overflowing from the interface does not block the internal passage of the spout 12.
The longitudinal height of the wide mouth section 12B is preferably set to an arbitrary value selected from the range of 1.2mm to 3 mm. More preferably, it is set to select any value within 2mm-3mm, for example 2mm, 2.5 mm. In the case where the user squeezes the main body 10, the liquid in the main body 10 is directly ejected from the narrow-mouth section 12A without contacting the wide-mouth section 12B. Thus, the jet size of the plastic container 100 will be directly determined by the diameter of the narrow mouth section 12A. Obviously, such a smaller jet may make it more convenient for the user to clean the contact lens.
Although the wide mouth section 12B has a larger cross-sectional area than the narrow mouth section 12A, the wide mouth section 12B still has a smaller cross-sectional area and lower rigidity, and therefore, it is preferable that the outer surface of the wide mouth section 12B is also provided with the above-described ribs 13.
The section 12A (the narrow mouth section 12A) having the smallest cross-sectional area as described above is set to have a quadrangular cross section as shown in fig. 3 in some preferred embodiments. Wherein one of the diagonals of the quadrilateral is coplanar with the stitching plane B-B. Preferably, the quadrilateral is rectangular.
In other embodiments, not shown, the cross-section of the section 12A (the throat section 12A) that will have the smallest cross-sectional area may be triangular, elliptical, etc. Based on the inventive concept described above with respect to the present disclosure, the longest line segment in these other forms of cross-section is also set to be coplanar with the press-fit plane shown in fig. 3 in an effort to prevent the narrow-mouth section 12A from being blocked by the slurry liquid during the process of manufacturing the plastic container 100.
Alternatively, the cap 20 above the main body 10 may be formed in a generally plate shape to facilitate the grip and screw of the consumer.
Alternatively, the bottle cap 20 is formed as a contact section 22 at a region connected with the bottle mouth 12, corresponding to the wide mouth section 12B of the main bottle body 10 described above. Similarly to the outer wall surface of the wide mouth section 12B described above, the vertical cross section of the outer wall surface of the contact region may be set to be semicircular as a whole.
The scope of the present disclosure is to be limited only by the following claims. Persons of ordinary skill in the art, having benefit of the teachings of the present disclosure, will readily appreciate that alternative structures to those disclosed herein are possible alternative embodiments, and that the disclosed embodiments of the present disclosure may be combined to create new embodiments, which also fall within the scope of the appended claims.
