[0059] The utility model will be described below in a preferred embodiment and in conjunction with the drawings.
[0060] As Figures 1-9 shown, the embodiment provides a spray shell 100, which comprises a main body 1 having a first accommodating cavity, the main body 1 comprising an upper cover 12 and a lower cover 11, the upper cover 12 and the lower cover 11 being separately arranged so that the first accommodating cavity forms a first cavity 1011 arranged on the lower cover 11 and a second cavity 1012 arranged on the upper cover 12. Figure 8 As shown, the first cavity 1011 is used for accommodating the bottle body 3 of the spray 200, the second cavity 1012 is used for accommodating the driver 4 of the spray 200, and the upper cover 12 and the lower cover 11 are detachably connected. Figure 6 As shown, the top of the upper cover 12 has a through hole for the spray head 5 of the spray 200 to extend out. By arranging the main body 1 of the spray shell 100 into the separately arranged upper cover 12 and lower cover 11, and the upper cover 12 and the upper cover 12 being detachably connected, the first cavity 1011 on the lower cover 11 is used for accommodating the bottle body 3 of the spray 200, and the second cavity 1012 on the upper cover 12 is used for accommodating the bottle body 3 of the spray, which facilitates the main body of the spray 200 to be placed into the first accommodating cavity, and the spray head 5 of the spray 200 to extend out through the through hole 1201, facilitating the patient to use. The spray shell 100 can realize wrapping and shielding of the main body of the spray 200, avoiding the influence of the experimental results due to the patient seeing the brand of the spray 200 during the blind study process.
[0061] That is, in the embodiment, when the upper cover 12 and the lower cover 11 are separated from each other, the spray 200 is placed into the first accommodating cavity, and then the upper cover 12 and the lower cover 11 are connected, realizing wrapping and shielding of the main body of the spray 200, wherein the main body of the spray 200 is the bottle body 3 for containing the medicament and the driver 4 for pressing the medicament.
[0062] The spray 200 in the present embodiment is a nasal spray 200. Of course, in other embodiments, the spray housing 100 can also be used to hold other sprays 200.
[0063] In the present embodiment, as shown in Figure 5 , Figure 6 and Figure 9 , the outer periphery of the upper cover 12 has a barb 121, the inner side of the lower cover 11 has a first annular protrusion 111, the outer diameter of the barb 121 is greater than the inner diameter of the protrusion, and the first accommodating cavity has a clearance space for the barb 121 to move in the vertical direction. This structure provides a specific structure of detachable connection of the upper cover 12 and the lower cover 11, and the detachable connection of the upper cover 12 and the lower cover 11 is achieved through the cooperation of the barb 121 and the first annular protrusion 111, which is simple and reliable. By providing the accommodating cavity with a clearance space for the barb 121 to move in the vertical direction, the upper cover 12 can move with the drive 4 of the spray 200 when the spray 200 is pressed to spray medicine.
[0064] The first annular protrusion 111 in the present embodiment refers to, as shown in Figure 5 and Figure 6 , the first annular protrusion 111 protrudes towards the axis of the spray housing 100 relative to the side wall of the clearance space for the barb 121 to move in the vertical direction, so that the annular protrusion can block the barb 121 to achieve the connection of the upper cover 12 and the lower cover 11. Specifically, the clearance space is arranged at the top of the second cavity.
[0065] Specifically in the present embodiment, the barb 121 is full along the circumference of the upper cover 12. That is, the barb 121 in the present embodiment is not a plurality of barbs 121 distributed discretely along the circumference of the upper cover 12, but is full along the circumference of the upper cover 12.
[0066] Of course, in other embodiments, a plurality of barbs 121 can be provided on the upper cover 12 to achieve detachable connection between the upper cover 12 and the lower cover 11. In more embodiments, the aerosol shell 100 can be configured such that the outer circumferential side of the upper cover 12 is provided with the barbs 121, the inner circumferential side of the lower cover 11 is formed with a sliding groove in which the barbs 121 can slide, the end of the lower cover 11 close to the upper cover 12 is the first connecting end 112, the sliding groove comprises a first sliding section, a second sliding section and a third sliding section, the first sliding section is provided at intervals along the circumference of the lower cover 11, the first sliding section extends to the first connecting end 112, the second sliding section connects the first sliding section and the third sliding section in the horizontal direction, the third sliding section is away from the first connecting end 112, and the second sliding section extends in the vertical direction. By providing the sliding groove with three sliding sections, the barbs 121 slide from the first sliding section into the third sliding section through the horizontally arranged second sliding section, and can move up and down in the third sliding section when the aerosol 200 is pressed and is not easy to come off the third sliding section, thereby achieving detachable connection between the upper cover 12 and the lower cover 11 and ensuring the reliability of the connection structure between the upper cover 12 and the lower cover 11. Details are not described here.
[0067] In the present embodiment, as shown in Figure 3 , the end of the lower cover 11 close to the upper cover 12 is the first connecting end 112, and the first annular protrusion 111 is arranged at the first connecting end 112. Compared with arranging the first annular protrusion 111 at the middle position of the lower cover 11, arranging the first annular protrusion 111 at the first connecting end 112 can save the manufacturing cost of the aerosol shell 100. Meanwhile, in the present embodiment, as shown in Figure 5 and Figure 6 , the end of the upper cover 12 close to the lower cover 11 is the second connecting end 122, and the barbs 121 are arranged at the second connecting end 122. Compared with arranging the barbs 121 at the middle position of the upper cover 12, arranging the barbs 121 at the second connecting end 122 can save the manufacturing cost of the aerosol shell 100. That is, in the present embodiment, the connection structure between the upper cover 12 and the lower cover 11 is arranged at the end portion.
[0068] In the present embodiment, as shown in Figure 1 , Fig. Figure 2 and Figure 7 , the aerosol shell 100 further comprises a cover, the cover has a second accommodating cavity 201 for accommodating the spray head, and the cover is detachably connected with the upper cover 12. By arranging the cover, the spray head 5 of the aerosol 200 can be protected to prevent damage to the spray head 5.
[0069] In particular, in the present embodiment, as shown in Figure 6 and Figure 7As shown, the upper surface of the cover 12 has a second annular protrusion, and the outer periphery of the second annular protrusion is interference-fitted with the inner periphery of the second receiving cavity 201. Specifically, the second annular protrusion is disposed on the upper surface of the cover 12 and surrounds the through hole at the top of the cover 12. The interference fit between the outer periphery of the second annular protrusion and the inner periphery of the second receiving cavity 201 enables a detachable connection between the cover 12 and the cap, resulting in a simple and reliable structure.
[0070] In this embodiment, as Figure 2 As shown, the inner circumference of the lower cover 11 is provided with a plurality of first vertical ribs 113, which are evenly distributed along the circumference of the spray housing 100. Simultaneously, the inner circumference of the upper cover 12 is provided with a plurality of second vertical ribs 123, which are evenly distributed along the circumference of the spray housing 100. In addition, the cap has a second receiving cavity 201 for accommodating the nozzle, and the inner circumference of the cap is also provided with a plurality of third vertical ribs 211, which are evenly distributed along the circumference of the spray housing 100. By providing vertical ribs in the spray housing 100, the spray 200 can be better fixed in the spray housing 100. The radial extension length of the vertical ribs can be set as needed according to the size of the spray 200. While fixing the spray 200, the vertical ribs provide a certain space between the outer periphery of the spray 200 and the inner periphery of the spray housing 100, avoiding the formation of a vacuum space inside the spray housing 100 due to the outer periphery of the spray 200 and the inner periphery of the spray housing 100 being in contact, which would make it difficult to remove the spray 200 from the spray housing 100.
[0071] Specifically, in this embodiment, each group of vertical ribs has 6 ribs. In other embodiments, the number of vertical ribs can be adjusted according to actual needs. When the number of vertical ribs in the same group is three or more, a better fixing effect can be achieved. For example, if the first vertical rib 113 is provided with three or more ribs, it can have a better fixing effect on the bottle body 3 of the spray 200. This will not be elaborated further here.
[0072] Specifically in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the first vertical rib 113 is arranged near the bottom of the lower cover 11, the second vertical rib 123 is arranged near the top of the upper cover 12, and the third vertical rib is arranged near the top of the sealing cover. Meanwhile, the radial extension length of the first vertical rib 113 near one end of the upper cover 12 is less than that near one end of the bottom of the lower cover 11, the radial extension length of the second vertical rib 123 near one end of the lower cover 11 is less than that near one end of the top of the upper cover 12. The radial extension length of the third vertical rib near one end of the upper cover 12 is less than that near one end of the top of the sealing cover. That is, along the direction of putting the aerosol 200 into the lower cover 11, the radial extension length of the first vertical rib 113 gradually increases to a proper size; along the direction of putting the aerosol 200 into the upper cover 12, the radial extension length of the second vertical rib gradually increases to a proper size; along the direction of putting the aerosol 200 into the sealing cover, the radial extension length of the third vertical rib gradually increases to a proper size. The change of the size of the vertical rib has a guiding effect on putting the aerosol 200 into the aerosol shell 100.
