Description

Technical Field

[0001] The invention relates to an infusion container, in particular to an infusion container with integrated hanging rings and a preparation method thereof. Background Art

[0002] Infusion bottles are bottles for medical liquids that are infused into the human body during infusion. At present, the commonly used infusion packaging in clinical practice are glass infusion bottles and PVC soft packaging bags. Glass infusion bottles are heavy, have high transportation costs, are large in size and occupy a large space, are fragile, and are easy to cause pollution caused by broken bottles, making them inconvenient to use; the plasticizer DEHP in PVC soft packaging is easily soluble in the liquid medicine, which is harmful to human health, and the combustion produces harmful gases and chlorides that cause environmental pollution. Polypropylene infusion bottles are the best packaging to replace traditional packaging. They are composed of polypropylene, a high-quality high-performance plastic, a special material for high-pressure disinfection solutions, and are widely used at home and abroad. Polypropylene infusion bottles have many advantages that glass bottles cannot match: they are lighter and less breakable than glass bottles, have good toughness and mechanical strength, and are convenient for transportation and use; they have stable chemical properties and good drug compatibility; the plastic bottles produced by the biaxial stretching process are more transparent and less deformable than those produced by the extrusion and blowing method; in addition, polypropylene infusion bottles do not contain plasticizers, do not react chemically with the liquid medicine, have good stability and can be stored for a long time, and they also have the advantages of high strength, good transparency, and high temperature sterilization resistance.

[0003] In the prior art, the utility model patent with Chinese patent application number CN201620194139.9 discloses a hanging ring integrated infusion bottle or bag. The hanging ring integrated infusion bottle or bag comprises an infusion bottle or bag and a hanging ring, the hanging ring is located at the bottom of the infusion bottle or bag and is an integrated structure with the infusion bottle or bag, the hanging ring comprises a fixed column fixedly connected to the bottom of the infusion bottle or bag and an annular component located at the lower end of the fixed column, a hanging ring hole is arranged inside the annular component, the fixed column extends into the hanging ring hole of the annular component, and is connected to the inner wall of one side of the hanging ring hole, a groove is arranged at the bottom of the infusion bottle or bag, the hanging ring is located in the groove, and the lowest level of the hanging ring is higher than the bottom of the infusion bottle or bag. The utility model arranges a groove structure at the bottom of the infusion bottle (bag), so that the lowest level of the hanging ring is lower than the bottom of the infusion bottle or bag, thereby making it easy for the empty infusion bottle or bag to stand firmly, which is convenient for the transportation of the empty bottle or bag. The infusion bottle or bag has the following disadvantages: 1. The hanging ring hole of the infusion bottle or bag is oval or track-shaped. After the hanging ring is lifted, it is difficult to keep the hanging ring in an upright state due to the single-point interference between the hanging ring and the groove at the bottom of the infusion bottle (bag), and there is a risk of "inaccurate hooking", which increases the labor intensity of medical staff; 2. The hanging ring of the infusion bottle or bag also includes a connecting belt arranged between the fixed column and the annular component, and the connecting belt has a fan-shaped structure, and the large end of the fan-shaped structure is connected to the inner wall of the hanging ring hole, and the small end is connected to the fixed column; due to the existence of the connecting belt, the difficulty of injection molding is increased, and defective products due to lack of glue in injection molding are prone to occur.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The groove of the present invention is provided with a resistance groove; the ring structure includes a ring body and a fixed column; the gripping part, the first extension arm, the first resistance arm, the fixed part, the second resistance arm, and the second extension arm are enclosed to form a ring body, and the ring body is a closed annular body; the first resistance arm and the first extension arm are welded to form a first resistance part, and the second resistance arm and the second extension arm are welded to form a second resistance part; the first resistance part and / or the second resistance part can resist the resistance groove when the annular body rotates to an upright state. With this design, when the annular body rotates to an upright state, the first resistance part and / or the second resistance part resist the resistance groove, which can ensure that the annular body of the ring structure remains in an upright state, avoids the risk of "inaccurate hooking", reduces the labor intensity of medical staff, and the ring structure will not become brittle; at the same time, since it does not have a connecting belt, it is easier to form, and can avoid the occurrence of defective products due to lack of glue in injection molding.

[0030] 2. The first supporting arm, the fixed part and the second supporting arm of the present invention are combined to form a "V"-shaped structure; with this design, during the rotation process, the first supporting arm and the second supporting arm need to be bent at the same time, and the bending strength is better. In addition, the glue is fed in two ways, and the closed ring is easier to form. Furthermore, the molding bottom mold can be designed with a triangular boss corresponding to the "V"-shaped structure area to provide the necessary conditions for the stretching rod to land smoothly, and has the function of straightening the fixed column to avoid leakage marks; the triangular boss is used to balance the force on the stretching rod to prevent "pulling deviation". The two ends of the V-shaped structure are respectively combined with the first extension arm and the second extension arm to form an M-shaped structure. With this design, the hanging ring is gradually stretched and straightened during use, and the hanging bottle is more vertical, which reduces the residual liquid medicine, improves the utilization rate of medicines, and reduces the pollution of medical waste to the environment.

[0031] 3. The first abutting arm and the second abutting arm of the present invention are distributed in mirror images on both sides of the fixing part, and a concave part is provided at the corresponding position of the first abutting arm and the second abutting arm. This design can form folds on the first abutting arm and the second abutting arm, making the rotation smoother and ensuring the stability of the rotation angle.

[0032] 4. The first abutting portion and the second abutting portion of the present invention are both arc transition sections. With this design, after bending, the arc surfaces of the two abutting portions touch the bottom wall of the abutting groove, thus avoiding damage to the bottom of the bottle.

[0033] 5. A first protrusion is also provided on the bottom wall of the abutment groove of the present invention at a position corresponding to the first abutment arm, one end of the first protrusion is welded to the side wall of the abutment groove, and the other end thereof is welded to the outer wall of the fixed column; a second protrusion is also provided on the bottom wall of the abutment groove at a position corresponding to the first abutment arm, one end of the second protrusion is welded to the side wall of the abutment groove, and the other end thereof is welded to the outer wall of the fixed column. This design can increase the connection area between the fixed column and the bottom wall of the abutment groove, strengthen the connection strength, and solve the problem of the fixed column breaking. At the same time, the first protrusion and the second protrusion can also play a guiding role, which can facilitate the annular body to rotate better into the abutment groove, and can play a better abutment role on the first abutment part and the second abutment part, so that the annular body can better maintain an upright state.

[0034] 6. The other end of the fixing column of the present invention is welded to the bottom surface or the outer side surface of the fixing part, and has strong firmness. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The groove 11 is also provided with a resisting groove 12; the lifting ring structure includes a lifting ring body 20 and a fixing column 30; the lifting ring body 20 includes a gripping portion 21 and a fixing portion 22; a first extending arm 211 is provided at one end of the gripping portion 21, and a second extending arm 212 is provided at the other end thereof, and a receiving space is formed between the first extending arm 211 and the second extending arm 212; the fixing portion 22 is located in the receiving space, and a first resisting arm 221 is provided at one end of the fixing portion 22, and a second resisting arm 222 is provided at the other end thereof; the first resisting arm 221 is fused with the first extending arm 211, and the second resisting arm 222 is fused with the first extending arm 211, and the second resisting arm 222 is fused with the second extending arm 211, and the first resisting arm 221 is fused with the second extending arm 211, and the second resisting arm 222 is fused with the first ... The holding arm 222 is welded to the second extension arm 212, so that the holding portion 21, the first extension arm 211, the first abutting arm 221, the fixing portion 22, the second abutting arm 222, and the second extension arm 212 are enclosed to form a ring body, and the ring body is a closed annular body; the first abutting arm 221 and the first extension arm 211 are welded to form a first abutting portion 23, and the second abutting arm 222 and the second extension arm 212 are welded to form a second abutting portion 24; one end of the fixing column 30 is vertically welded to the bottom wall of the abutting groove 12, and the other end thereof is welded to the bottom surface of the fixing portion 22;

[0052] In the present invention, welding specifically refers to fixed connection by melting.

[0053] During actual use, after the hanging ring structure is lifted up, the first abutment portion 23 and / or the second abutment portion 24 can abut against the bottom wall of the abutment groove 12 when the annular body rotates to an upright state, so that any abutment portion can be fixed at a single point, or fixed "one by one". With a slight intervention of the thumb, both the first abutment portion 23 and the second abutment portion 24 can abut against the side walls of the abutment groove 12, thereby ensuring that the annular body of the hanging ring structure remains in an upright state (the annular body and the bottom of the infusion bottle are approximately 90°), avoiding the risk of "inaccurate hooking" and reducing the labor intensity of medical staff; at the same time, since it does not have a connecting belt, it is easier to mold and can avoid defective products due to insufficient glue in injection molding.

[0054] As a preferred embodiment, the first supporting arm 221, the fixed portion 22 and the second supporting arm 222 are enclosed to form a "V"-shaped structure; with this design, during the rotation process, the first supporting arm 221 and the second supporting arm 222 need to be bent at the same time, and the bending strength is better.

Furthermore, the molding bottom mold can be designed with a triangular boss corresponding to the "V"-shaped structure area to provide the necessary conditions for the stretching rod to land smoothly, and has the function of straightening the fixed column 30 to avoid leakage marks; the triangular boss is used to balance the force on the stretching rod to prevent "pulling deviation". The two ends of the V-shaped structure are respectively enclosed with the first extension arm 211 and the second extension arm 212 to form an M-shaped structure. With this design, the hanging ring is gradually stretched and straightened during use, and the hanging bottle is hung closer to verticality, which reduces the residual liquid medicine, improves the utilization rate of medicines, and reduces the pollution of medical waste to the environment.

This design can form folds on the first abutting arm 221 and the second abutting arm 222, making the rotation smoother and ensuring the stability of the rotation angle.

[0057] As a preferred embodiment, the first abutting portion 23 and the second abutting portion 24 are both arc transition sections. With this design, after bending, the arc surfaces of the two abutting portions abut against the bottom wall of the abutting groove 12, avoiding damage to the bottom of the bottle.

[0058] As a preferred embodiment, the abutment groove 12 is a circular groove. More specifically, the bottom wall of the groove is connected to the inner side wall of the abutment groove 12 by a transitional arc surface. This design can facilitate the annular body to rotate better into the abutment groove 12, and play a good guiding role.

[0059] As a preferred embodiment, the long axis direction of the annular body is arranged along the long axis direction of the infusion container body; such a design is conducive to placing the annular body completely in the groove of the infusion bottle without any gap, so that it stands stably.

[0060] As a preferred embodiment, the fixed column 30 is located at the center of the bottom of the infusion container body, and the plane where the annular body is located is perpendicular to the extension direction of the fixed column 30; such a design is conducive to ensuring that the infusion bottle remains in a vertical state during injection and preventing waste of injection liquid.
