Description

Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to a convenient-to-use liquid medicine delivery device. Background Art

[0002] At present, in the fields of medicines and cosmetics, in order to administer preparations containing drugs, active ingredients, pharmaceutical products, cosmetics or the like, a delivery device in the form of an aerosol needs to be used. That is, generally, a spray outer cover for generating an aerosol needs to be installed on a container to achieve the effect of delivering the medicine at a limited distance, so as to help the user obtain the liquid medicine or cosmetics more accurately.

[0003] However, since the spray outer cover is a separate part and has a large volume, when it is used in combination with a liquid medicine bottle, the outer cover needs to be installed on the pump head of the liquid medicine bottle. After use, it needs to be disassembled and stored separately, which brings great inconvenience to the user.

[0004] In addition, when using the existing products with the spray outer cover and the liquid medicine bottle, there is no force application point. When disassembling after use, it is sometimes not easy to pull out the outer cover. And when the bonding force between the outer cover and the bottle body is too large, when the user disassembles the outer cover, if the force is not controlled well, the internal push button may be pulled off together, thus damaging the device.

[0028] The following specifically describes the technical solution protected by the present utility model in conjunction with the accompanying drawings.

[0029] The present utility model provides a medicament delivery device that is convenient to use and can also be used to deliver cosmetics or food. It includes a container 1 and a nozzle disposed at the opening of the container 1. In order to form an aerosol of a drug, cosmetic or other similar substance and effectively apply it, the nozzle generally includes a pump head (not shown in the figure) and a spray outer cover 2 with a relatively large size. The pump head is disposed inside the opening of the container 1, and the spray outer cover 2 covers the pump head. By applying a pressing force to the pump head, the content in the container is pumped out and effectively delivered through the spray outer cover 2.

[0030] As Figure 1 shown, the present utility model is proposed for the storage problem of the spray outer cover 2 with a relatively large size. Specifically, the spray outer cover 2 is in a trumpet shape. By providing a support part 21 on the outer circumference below the opening of the spray outer cover 2, a multi-point support structure is formed with one side of the bottom of the container 1. In one embodiment, the support part 21 is two support ribs extending along the axis direction of the spray outer cover 2, and the two support ribs form a three-point support with the container; in other embodiments, the support part is two groups of bump units convexly provided on the outer peripheral surface of the spray outer cover, and each group of bump units includes at least one bump. The shape of the bump is not limited and can be a three-dimensional figure such as a hemispherical shape, a semi-ellipsoidal shape, a frustum shape or a trapezoidal shape. Thus, after use, when the container is placed obliquely, there is no need to disassemble the spray outer cover 2, and stable placement can be achieved by using the three-point support structure, improving the convenience of use.

[0031] Furthermore, the cross-section of the support rib is trapezoidal.

[0032] In other embodiments, the support portion 2 can also be two groups of supporting ribs extending circumferentially along the circumferential surface of the spray outer cover. The number of each group of supporting ribs can be multiple, and force points are formed by the friction between the placement plane. Two force points are formed on the spray outer cover by the two groups of supporting ribs. After the container is tilted, a third force point is formed on one side of the bottom of the container, thereby obtaining a three-point support structure, so that the delivery device can be placed stably.

[0033] See also Figures 2 to 5 The spray cover of the existing products has no force application point, and it is sometimes difficult to pull out the cover when it is disassembled after use. To solve this problem, the spray cover of this embodiment is designed with a pressing and pulling structure. Specifically, the spray cover includes a cover body 20 and a connecting part 3 covered on the pump head. The connecting part 3 includes a connecting wall 30 covering the pump head and a pressing wall 31 formed on the upper end surface of the connecting wall 30. A wing 32 extends outward from the edge of the pressing wall 31. When in use, the pressing wall 32 is pressed and force is applied, and the wing 32 is used to pull out the spray cover.

[0034] like Figure 5 As shown, the upper surface of the pressing wall 31 is a concave arc surface, which gradually increases from the middle to the two ends, so that fingers can be placed comfortably on it to apply force, that is, through the design of the arc, it matches the human fingers, which is convenient for users to press, and the arc of the pressing surface allows users to press more easily, and when disassembling, the protruding wings 32 can be used to facilitate the human hand to grasp and pull the spray cover 2 relative to the pump head.

[0035] like Figure 4 The connecting wall 30 is provided with a clearance opening 36 at the lower part of the main body of the outer cover, and guide plates 33 are provided on both sides of the clearance opening 36 to facilitate the installation of the spray outer cover. Furthermore, at least one guide rib 34 is provided on the inner side wall of the guide plate 33, and at the same time, a plurality of vertical reinforcing ribs 35 are evenly provided on the inner side wall of the connecting wall 30. The provision of the reinforcing ribs 35 can not only increase the strength of the connecting part 3, but also guide the left and right, which is more conducive to the assembly and cooperation between the connecting part 3 and the container 1.

[0036] The utility model has a simple structure, is more conducive to mold production, and is more convenient to use. The outer cover can be pulled out or not pulled out, and will not fall over when stored together with the container 1.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
