Description

Spray structure of container

This creation relates to the field of use of containers, especially a spray structure of containers.

Japanese Design Patent No. 1495055 discloses a packaging container, which has a single inlet and outlet to guide liquid into the container or out of the container. In addition, the entrance is provided with a base, an inner cover and an outer cover. The base is a hollow pipe body, and the pipe body has a top end and a bottom end, and the bottom end locks the entrance and exit of the container. The inner lid locks into the inside of the top end of the base, allowing liquid to be sprayed out of the outside of the container through some fine holes of the inner lid. The outer cover is locked on the outer side of the top end of the base, and has a shielding and closing effect on the inner cover.

Similar containers are sold in the market, with one more hose than the '055 patent case. The two ends of the hose are defined as a spout and a conical portion. The spout continues through the central hole of the inner cover with the hose to continue into the container until the conical portion is blocked by the wall surface of the inner cover surrounding the central hole. During the locking of the base by the outer cover, a convex point is formed on the outer cover facing the central hole, and the convex point blocks the conical portion and prevents gas from entering the container through the hose.

Because of the single design of the inlet and outlet, the container must be inclined at a certain angle so that the liquid can flow out of the container through the inlet and outlet below the liquid level. However, the hose does not closely contact the wall surface of the inner cover surrounding the central hole, so that the hose may be detached from the inner cover. In short, the '055 patent case does not have a design that allows air to smoothly enter the interior of the volume and avoid negative pressure. The conventional technology in the market has a vent tube in the middle, but the inner end of the nozzle needs to be able to protrude from the liquid surface.

Secondly, the purpose of the hose is to allow air to enter the container, to prevent liquid from flowing out of the container, and to cause a negative pressure inside the container to form a negative pressure with the outside of the container due to lack of air, which prevents liquid from flowing out. For example, the lid of the domestic kettle has vent holes so that the liquid in the container can flow out smoothly. Therefore, the inner end of the commercially available hose must wait for the liquid level in the container to be lower than the inner port of the hose before the liquid can flow out smoothly. Otherwise, the liquid will flush out of the hose, not only reducing the spray function, but also blocking the air intake function, so that a tank of liquid can be sprinkled up quickly. When in use, the container usually has to be shaken a few times due to the presence of negative pressure, so that the liquid can be sprayed smoothly.

Therefore, how to improve the container without the need for hoses has become an urgent problem to be solved in this creation.

One of the main purposes of the spraying structure provided by the creator of this case is to use the mechanism of fine holes and the structure of the switch, which does not require a hose and avoids the relatively negative pressure inside the container, so that the container can spray liquid smoothly.

One of the main purposes of this creation is to use a container with double openings, install a spray structure and an air-tight device at the same time, and release the air-tight device together with the ventilation effect.

Due to the achievement of the above purpose, this creation includes: a container with an outlet; a base detachably coupled to the outlet of the container; at least one through-hole formed in the base to communicate with the container outlet; one with a number of fine holes The inner cover is connected to the base; an operation panel is arranged between the base and the inner cover, and the operation panel is rotated to close the through hole of the base; and at least one through hole is formed in the operation panel, and the through hole of the operation panel is rotated according to the rotation Communicate with the through hole of the base.

The container of this creation also has an entrance for combining an airtight device. Wherein, the airtight device includes: an upper cover; a bottom cover combined with the inlet of the container; an inner cylinder formed on the bottom cover to communicate with the inlet; and, a set of conical cylinders are connected to the upper cover and the inner cylinder for telescopic movement.

In addition, the spray structure of this creation, with the fine holes of the inner cover and the switch-like mechanism of the operation panel, is enough to allow the container to spray liquid. Moreover, the airtight device of the present invention connects the air flow inside and outside the container, so there is no negative pressure inside the container, and the flow of liquid is naturally smooth.

In order to make the purpose, structure, features and advantages of this creation more obvious, one or more preferred embodiments are described in detail below in conjunction with the accompanying drawings.

FIG. 1 is a front view illustrating that the container 10 includes an outlet 13 and an inlet 14. The outlet 13 of the container 10 is provided with a spray structure 20, and an airtight device 50 is installed at the inlet 14.

In the figure, the container 10 is a bottle, and the bottle has a wall 11 with a certain thickness. The wall 11 encloses the interior of the bottle into a chamber 12 of a certain shape. The chamber 12 leads to the outlet 13 and the inlet 14. The container 10 further has a grip portion 17. The grip portion 17 is a tube connected to the wall 11, and the tube is connected to the chamber 12 and connected together.

2 and 3 are a perspective view and a cross-sectional view, showing that the spray structure 20 is exploded into a base 21, an outer cover 30, an inner cover 32, and an operation panel 40. FIG. 4 is a combined view, and the cutting angle of FIG. 5 can be seen along the line AA, showing that the outer cover 30 and the inner cover 32 are detachable in combination with the base 21, restricting the operation panel 40 from opening relative to the base 21 1. Close the two positions to move back and forth to change the use of the spray structure 20.

In terms of the base 21, a periphery of the transverse portion 22 is connected to a circle of longitudinal portions 23, which together form a U-shaped cross section. Wherein, the outer side of the transverse portion 22 protrudes two pieces of coupling walls 25, and these coupling walls 25 surround the periphery of a group of through holes 26 penetrating the transverse portion 22 along the circumferential direction. Two bead grooves 28 sink into the longitudinal portion 23 and are located on both sides of the lateral portion 22. Each bead groove 28 receives a bead 36 and an elastic member 37. The elastic member 37 is a compression spring that pushes the bead 36 toward the opening of the bead groove 28. The wall of the longitudinal portion 23 around the opening of the bead groove 28 restricts the partial exposure of the bead 36 without leaving the bead groove 28.

In addition, a piece of gasket 24 is adhered to one side of the lateral portion 22 different from the bonding wall 25, and this gasket 24 does not seal the opening of the through hole 26. A spiral pattern is formed inside the longitudinal portion 23, and the spiral pattern helps the base 21 to lock the outlet 13 of the container. During the locking period, the gap from the outlet 13 to the lateral portion 22 is blocked by the gasket 24, so the gasket 24 has a leak stop effect, and the set of through holes 26 is reserved to enter and exit the container chamber through the outlet 13.

In terms of the operation panel 40, a thin-walled portion 42 peripherally joins a circle of thick-walled portions 45, and collectively encloses a groove 41, and the groove 41 sinks into one side of the operation panel 40. Two arc-shaped holes 44 penetrate the thin-walled portion 42 and communicate with the groove 41. The arc-shaped holes 44 surround the periphery of a group of through-holes 43 passing through the thin-walled portion 42 in the circumferential direction. Two sets of positioning holes 46 are formed in the thick-walled portion 45 and located on both sides of the groove 41, and each set is composed of two positioning holes 46 separated by a certain distance.

The arc-shaped hole 44 faces the corresponding coupling wall 25 and brings the operation panel 40 and the base 21 close to each other until the groove 41 receives the lateral portion 22. At this moment, the thick-walled portion 45 fills the gap of the longitudinal portion 23, and the associated thin-walled portion 42 is substantially parallel to the lateral portion 22. One of the two sets of positioning holes 46 respectively receives the portion where the bead 36 exposes the bead groove 28, ensuring that the operation panel 40 stays in the open position. In the open position, the two groups of through holes 26, 43 (see the solid line in Figure 5) are aligned with each other.

The outer cover 30 and the inner cover 32 have the same U-shaped cross section. Wherein, the inner cover 32 has an external threaded section 33 and a convex curved portion 34, and a plurality of fine holes 35 are formed in the convex curved portion 34 in a straight line, circumferential or spiral direction.

When the externally threaded section 33 is screwed to a section of thread 27 inside the coupling wall 25, the inner cover 32 is locked between the two coupling walls 25, which blocks the thin wall portion 42 so that the operation panel 40 cannot leave the base 21. At the same time, the convex curved portion 34 faces the thin-walled portion 42 to keep the fine hole 35 and the two sets of through holes 26 and 43 open.

In addition, two pieces of water-stopping gaskets 421 and 422 are adhered to both sides of the thin-walled portion 42 and can be operated in synchronization with the operation panel 40. Wherein, the water stop gasket 421 fills the gap between the opening end of the inner cover 32 and the operation panel 40, but does not seal the through hole 43 and the arc-shaped hole 44. The water stop gasket 422 also does not seal the through hole 43 and the arc-shaped hole 44, and determines whether the through hole 26 of the lateral portion 22 is sealed.

The outer cover 30 forms an internally threaded section 31 that is screwed to a section of thread 29 on the outer side of the coupling wall 25 so that the outer cover 30 cooperates with the operation panel 40 to protect the inner cover 32. A washer 301 is adhered to the opening of the outer cover 30, and the washer 301 contacts the operation panel 40 to produce a leakage stop.

Looking back at Figure 1, fluid 15 is injected into the chamber 12 of the container 10. Even if the container 10 is placed flat on a supporting surface (such as a tabletop), the fluid 15 will usually enter and exit the hollow grip portion 17 and the liquid level 16 is preferably lower than the inlet 14.

The fluid 15 referred to herein generally refers to water or a liquid having a medicinal effect, such as a liquid for cultivation, a liquid for disinfection, a liquid for spraying, and a liquid for other uses.

As shown in Fig. 6, the spray structure 20 is removed from the cover. The container 10 is inclined to an angle by force, causing the fluid 15 in the chamber 12 to flow toward the outlet 13 in the direction of arrow B. Because the operation panel 40 is in the open position, the fluid 15 flows to the fine holes 35 through the two sets of through holes 26, 43 (see the solid line portion in FIG. 5). The diameter of the fine hole 35 is small, and the fluid 15 is divided into fine liquid columns. The pressure of the liquid column is large, so that it can be sprayed far away.

In FIG. 5, one of the two ends of the arc-shaped hole 44 is close to the coupling wall 25, and the other end is kept at a distance from the coupling wall 25 to ensure that the operation panel 40 can reciprocate relative to the base 21. For example, the operation panel 40 rotates in the direction of arrow A, and the beads 36 catch other positioning holes 46 to ensure that the operation panel 40 moves from the open position to the closed position.

In the closed position, the set of through-holes 43 is displaced from the solid line portion to the dotted-line portion, and is no longer aligned with the through-hole 26 of the lateral portion 22 (see Figures 2 and 3), so that the operation panel 40 blocks the fluid 15 (refer to Figure 6) Do not flow out of the base 21.

Next, referring to FIGS. 1 and 8, it is explained that the airtight device 50 is composed of a bottom cover 51 with internal threads, an upper cover 55 with internal threads, and a support structure 60 with telescopic characteristics. Wherein, the bottom cover 51 forms an inner cylinder 52, and the two ends of the inner cylinder 52 are respectively a central hole 53 and an opening 56, the central hole 53 communicates with the opening 56, the opening 56 is surrounded by a ring of the bottom cover 51 Surrounded by a wall 54, the ring wall 54 is provided with external threads to lock the upper cover 55.

The support structure 60 is composed of a plurality of cone cylinders inserted or nested, defining these cone cylinders as a cone cylinder 61 with the largest diameter, a set of cone cylinders 62 with decreasing diameters, and a cone cylinder 63 with the smallest diameter. Both ends of each conical cylinder maintain an inclination angle 65, and the inclination angle 65 ranges from 1° to 5°. Wherein, the expanded end of the conical tube 61 is adhered to the upper cover 55, and a set of air holes 64 is formed between the expanded end and the reduced end. The conical cylinder 63 adheres to the wall around the central hole 53 with the reduced end, so that the expanded end of the smallest diameter cylinder 63 and the reduced end of the largest diameter cylinder 61 are connected together by the set of conical cylinders 62.

When the bottom cover 51 is locked and fixed at the inlet 14, the central hole 53 of the inner cylinder 52 communicates with the container chamber 12 of the container 10, and the upper cover 55 locks the ring wall 54 to drive the conical cylinder 61 toward the inner cylinder 52, so that the group The cone 62 and cone 63 overlap each other, reducing the length of the support structure 60.

As shown in FIGS. 6 and 7, the screw relationship between the ring wall 54 and the upper cover 55 is released. The upper cover 55 is forced away from the ring wall 54. The conical cylinder 61 drives the set of conical cylinders 62 to extend outward, relatively increasing the length of the support structure 60. Because of the inclination angle 65 (see FIG. 8), the conical cylinders 61, 62, and 63 are pressed against each other to support the bottom cover 51 and the upper cover 55 at a certain distance.

At the same time, the set of air holes 64 communicates the chamber 12 with the outside of the container 10. In this way, the outside air flows through the central hole 53 in the direction of the arrow C (see FIG. 7 ), enters the inlet 14 of the container 10, and the supplementary liquid level 16 descends and gradually expands the upper space of the chamber 12, making the flow of liquid smoother.

In addition, after the bottom cover 51 is removed, the liquid is injected into the container through the inlet 14.
