Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging, and in particular to an oral liquid bottle. Background Technology

[0002] Oral solution bottles are single-dose packaging for oral solutions or suspensions, offering convenience in carrying and administration, and ease of storage. Currently, most oral solution bottles use aluminum-plastic caps with rubber stoppers, which presents problems such as the straw being easily broken or difficult to insert, and also presents difficulties in inhalation due to air pressure issues. Utility Model Content

[0003] To address the problem that the straw in existing oral liquid bottles is difficult to insert, making it difficult for patients to inhale the liquid, this invention provides an oral liquid bottle with an easy-to-insert straw that can balance internal and external air pressure, making it easier for patients to inhale the liquid.

[0004] The oral liquid bottle provided by this utility model adopts the following technical solution:

[0005] An oral liquid bottle includes a bottle body, a bottle mouth, and a bottle bottom. The bottle mouth is provided with a sealing plug and an outer cap. The sealing plug has an opening in the middle and a sealing membrane inside. The sealing membrane has a structure that is thin in the middle and thick at the edges. The thin part in the middle is a puncture part. The sealing membrane is also provided with a vent hole, and a flow guide part is provided below the vent hole.

[0006] Preferably, the sealing membrane is made of rubber.

[0007] Preferably, the cross-section of the vent is funnel-shaped, and the guide portion is formed by extending the edge of the vent at the opening inside the bottle and is integrally formed with the sealing film; the guide portion covers the opening inside the bottle of the vent, and when the pressure difference between the air pressure inside the bottle and the external air pressure is formed due to the liquid being pumped, the outside air will enter the bottle by pushing open the guide portion through the vent.

[0008] Preferably, the inner wall of the bottle has a conical structure, and the outer wall of the bottle is provided with a reinforcing rib.

[0009] When a liquid flows out of a container, its flow rate is closely related to the cross-sectional area and shape of the container outlet. Designing the inner wall of the bottle as a gradient cone can guide the liquid to flow out more smoothly and completely. By gradually reducing the diameter from the bottom of the bottle to the mouth, the liquid can be forced to gather towards the center, reducing residue at the corners.

[0010] Preferably, the bottom of the bottle is concave inward and is provided with a second reinforcing rib;

[0011] Preferably, the inner wall of the bottle mouth is provided with a fixing protrusion, and the outer wall of the sealing plug is provided with a fixing groove. The fixing protrusion on the inner wall of the bottle mouth cooperates with the fixing groove on the sealing plug so that the sealing plug is snapped into the bottle mouth. When the outer cap is removed, the sealing plug will not pop out automatically.

[0012] Preferably, the sealing membrane is integrally formed and connected inside the sealing plug;

[0013] Preferably, the vent is a one-way vent, and the number of one-way vents is N, where N≥2;

[0014] Preferably, the sealing plug is made of hard rubber and the outer cover is made of aluminum-plastic composite, wherein the outer cover can be completely removed at once.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention employs a perforated sealing plug with an internal sealing membrane that is thinner in the middle and thicker at the edges. A puncture hole is located in the center of the sealing membrane, facilitating easy insertion of the straw. The sealing membrane has a one-way vent, which, in conjunction with the flow guide, balances the air pressure inside and outside the bottle, allowing the patient to easily inhale the medication.

[0017] The outer cap of this invention can be peeled off in one go. If you forget to take the straw, you can pull out the sealing plug and pour the liquid directly into your mouth or into a container to take it. The inner wall of the bottle is designed with a gradient conical structure, which facilitates the one-time pouring of the liquid and makes it less likely to leave residue.

[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail below:

[0025] This utility model discloses an oral liquid bottle, such as... Figure 1As shown, the oral liquid bottle includes a bottle body 1, a bottle mouth 11, an outer cap 5, and a bottle bottom 12. The outer wall of the bottle body 1 is provided with a reinforcing rib 2, which has an anti-slip function, making it easy for users to grip and preventing it from slipping. The bottle bottom 12 is concave inward, and a second reinforcing rib 21 is provided in the concave area, which helps the bottle body 1 to be placed stably.

[0026] like Figure 2-5 As shown, the bottle mouth 11 is also provided with a sealing plug 3. The outer wall of the sealing plug 3 is provided with a fixing groove 31, and the inner wall of the corresponding bottle mouth 11 is provided with a fixing protrusion 32, which can make the sealing plug 3 snap into the bottle mouth 11. The sealing plug 3 has a hole in the middle to facilitate the passage of the straw. The sealing plug 3 has a sealing film 4 integrally formed inside. The sealing film 4 is made of rubber and has a structure that is thin in the middle and thick at the edges. The thin part in the middle is the puncture part 41, and the thick part at the edges is provided with a vent hole 42. The cross-section of the vent hole 42 is funnel-shaped. The guide part 43 is formed by extending the edge of the vent hole 42 at the opening inside the bottle and is integrally formed with the sealing film 4. The guide part 43 covers the opening inside the bottle of the vent hole 42. When the air pressure inside the bottle is different from the external air pressure due to the liquid being pumped, the outside air will enter the bottle through the vent hole 42 and push open the guide part 43, which helps to balance the air pressure inside and outside the bottle.

[0027] The outer cap 5 is made of aluminum-plastic material and can be peeled off in one go, making it convenient to pull out the sealing plug 3 when there is no straw; the inner wall of the bottle body 1 is designed with a conical structure, which makes it easy to pour all the medicine into the mouth or container at one time, and it is not easy to leave residue.

[0028] The implementation principle of this utility model embodiment is as follows:

[0029] When taking the oral liquid, the user first holds the bottle at the reinforcing rib 2 with one hand, and peels off the outer cap 5 with the other hand. If there is no straw, the sealing stopper 3 can be pulled out directly, and the liquid can be poured directly into the mouth or into another container before taking it. If there is a straw, the user can directly puncture the sealing membrane 4 with the straw to draw the liquid. The sealing membrane 4 has a one-way vent 42, which helps to balance the air pressure inside and outside the bottle, making it easy for the patient to draw the liquid without effort.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
