Description

  The present invention relates to a liquid dispensing member and container having a residual dripping prevention structure.

  A container for storing a liquid such as a medicine generally includes a container body and a member such as a cap or a cap having a liquid outlet for pouring the medicine to the outside, and the member is provided at the mouth of the container body. It is mated. When dispensing the internal chemicals in such a container, open the lid or cap of the liquid spout and tilt the container upright (in a horizontal state) to incline the internal chemicals into the liquid spout Pour out from.

  When the container is returned from the inverted state to the upright state after the liquid is completely dispensed, the liquid may remain near the liquid outlet. The remaining liquid usually cannot return to the inside of the container and drips outside the container.

  In order to solve such a problem of liquid dripping to the outside of the container, there is a technique related to a dispensing cap described in Patent Document 1 below. The pouring cap according to the technology is assembled to the mouth of the container body 3, the cap body 1 with the pouring cylinder 5 standing from the top wall 4, and hinged to the cap body 1 so as to be openable and closable. And an upper lid 2 provided with a fitting cylinder 7 that is closely fitted into the dispensing cylinder 5 in a state. The dispensing cylinder 5 includes a cylindrical tube piece 8 standing from the top wall 4 and a flange piece 9 protruding outward from the upper end of the outer peripheral surface of the cylinder piece 8. l is 2 mm or more.

  According to the prior art described in Patent Document 1, the content liquid flows and is poured out on the flange piece 9 by tilting the container. When the container is returned to the upright state after the dispensing, the content liquid remaining on the outer peripheral edge of the flange piece 9 is pulled back into the dispensing cylinder 5 and thus into the container by the surface tension. Therefore, it is possible to prevent the content liquid from remaining on the outer peripheral edge of the flange piece 9.

  However, in the above prior art, even if the pouring cap is returned to the upright position, the liquid remaining on the lower end of the outer peripheral edge of the flange piece 9 is not pulled back only by the surface tension on the flange piece 9, and the residual liquid is not removed from the outer wall of the container. There was still a problem of dripping down the road.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIGS. 1A to 1E show an inner plug 1a that is a member for liquid dispensing according to the first embodiment of the present invention. As will be described later, the inner plug 1a is a member that is fitted into a container for storing a liquid such as a medicine and allows the liquid to be poured out. The inner plug 1a can be made as an integral part by injection molding, but is not limited thereto.

  As shown in FIG. 1B, the inner plug 1a includes a base portion 2a that engages with a mouth portion of a container (not shown), and a nozzle portion 3a that extends from the base portion 2a. As best shown in FIG. 1 (d), the base 2a is engaged with a hollow engaging portion 4a that is a portion engaged with the mouth of the container, and with the end of the mouth of the container, and the inner plug 1a. And a connecting portion 6a for connecting the flange 5a to the nozzle portion 3a.

  As shown in FIG. 1D, the nozzle portion 3a is formed in an internal passage 7a through which liquid from the container passes, an outlet 8a through which the liquid that has passed through the internal passage 7a flows, and an outer periphery of the outlet 8a. Nozzle tip portion 9a.

  As shown in FIGS. 1 (a), 1 (c) and 1 (d), the nozzle tip 9a has an inner surface 10a extending from the outlet 8a and the edge of the nozzle tip 9a as a boundary. An outer surface 11a opposite to the inner surface 10a and one residual liquid preventing passage 12a penetrating between the inner surface 10a and the outer surface 11a are provided. In the first embodiment, the residual liquid prevention passage 12a is a substantially elliptical through-hole formed below the pouring position 14a.

  As shown in FIGS. 1B and 1D, the nozzle portion 3a is formed as an oblique truncated columnar body, and the oblique truncated front end portion of the columnar body is the nozzle distal end portion. 9a is defined, and the highest position of the edge of the nozzle tip 9a from the base 2a is the pouring position 14a where the liquid flowing out from the outlet 8a flows out on the inner surface 10a and is poured out. The inner surface 10a of the nozzle tip 9a is formed so that the liquid flowing out from the outlet 8a flows on the inner surface 10a and is discharged from the pouring position 14a to the outside. Therefore, the inner surface 10a has a curved surface that is at least partially convex, and is formed so that the liquid that has exited from the outlet 8a is guided to the dispensing position 14a.

  In addition, a convex lip portion 13a is formed on the nozzle tip portion 9a along at least a part of the edge including the dispensing position 14a. The lip portion 13a may be formed to have the largest width at the pouring position 14a (FIG. 1A).

  Referring to the bottom view of FIG. 1 (e), the columnar portion 3a includes an inlet 17a at the end of the internal passage 7a opposite to the outlet 8a. Four grooves 16a extending radially outward from the inlet 17a are formed on the inner wall surface 15a of the connecting portion 6a around the inlet 17a. These grooves 16a are arranged so that the angles formed by the adjacent grooves are equal (90 degrees in this embodiment). The groove 16a extends to the inside of the side wall of the engaging portion 4a. The connecting portion 6a and the inner wall surface 15a of the connecting portion 6a are inclined with respect to the internal passage 7a.

Next, the operation of the inner plug 1a according to the first embodiment will be described with reference to FIG.
FIG. 2A shows an upright state in which the inner plug 1a according to the first embodiment is inserted into the mouth portion 21 of the container 20 containing a liquid 30 such as a medicine and is erected.

  FIG. 2 (b) shows a horizontal inverted state when the container 20 is first inverted approximately horizontally from the upright state of FIG. 2 (a). In this state, as shown by the arrow, the liquid 30 passes through the hollow portion of the base portion 4a, enters the inlet 17a, passes through the internal passage 7a, and exits from the outlet 8a. The liquid 30 flowing out from the outlet 8a flows on the inner surface 10a of the nozzle tip portion 9a and forms a droplet 31 at the dispensing position 14a at the tip of the lip portion 13a. The droplet 31 is dropped from the dispensing position 14a to a target position such as an affected part (not shown).

  Although the container 20 is in the state shown in FIG. 2B, the liquid may naturally flow to the dispensing position 14a at the tip to form the droplet 31, but the user (not shown) The liquid in the container may flow out of the outlet through the internal passage 7a with the pressure when the container 20 is pushed to form the droplet 31, and the droplet may be dropped.

  FIG. 2C shows another horizontal inverted state of the container 20 after the droplet 31 is dropped. When the liquid droplet 31 is dropped several times from the dispensing position 14a in the horizontally inverted state of FIG. 2B described above, the liquid is back of the convex lip portion as shown in FIG. 2C. May wrap around. In this case, the liquid that has flowed to the vicinity of the residual liquid prevention passage 12a without forming the liquid droplet at the dispensing position 14a forms the liquid droplet 31. The droplet 31 is dropped at a target position such as an affected part (not shown). The same applies thereafter.

  FIG. 2 (d) shows an initial stage state when the container 20 is gradually returned from the horizontally inverted state of FIG. 2 (c) to the upright state. As shown in FIG. 2 (d), when gradually returning from horizontal to erect, the liquid droplet 31 that has come out from the residual liquid prevention passage 12a is formed inside and inside the residual liquid prevention passage 12a. It is drawn into the internal passage 12a by the surface tension of the liquid surface contacting the convex curved surface of the surface 10a and the outer surface 11a of the nozzle portion 3a. On the other hand, as will be described in detail later, in the conventional technique in which the residual liquid prevention passage 12a does not exist, when the droplets formed from the nozzle tip to the outside are returned to the upright position, the surface tension is isolated. Since there is not enough, it will not be drawn into the container, will remain outside, and in some cases will drip and flow.

  FIG. 2 (e) shows the container 20 that has been returned to a more upright state than FIG. 2 (d). As the container 20 approaches the upright position, the liquid 34 drawn into the internal passage 12a attempts to return into the container by gravity, and the force to return returns to the inner surface 10a via the intermolecular force of the liquid. Since it is transmitted to the liquid remaining on the liquid and the liquid that has flowed outside from the residual liquid prevention passage 12a, these remaining liquids are also drawn into the container 20. On the other hand, the liquid in the internal passage 7a also has a force to stay in the internal passage due to capillary action, but the liquid 34 flows into the container 20 as the liquid 35 through the groove 16a. As a result, the liquid in the internal passage 7a flows into the container 20 as the container 20 approaches erect.

FIG. 2 (f) shows a state in which the container 20 is completely returned to the upright position. As shown in FIG. 2 (f), the liquid that is to remain in the internal passage 7a due to the capillary action is guided into the container by the groove 16a, so that there is no liquid in the nozzle tip 9a and the internal passage 7a. No longer remains. As a result, the air in the container 20 communicates with the outside air, so that there is no risk of liquid ejection at the next use.
For comparison with the present embodiment, FIG. 16 shows an operation when the container fitted with the inner stopper according to the prior art is returned from the horizontally inverted state to the upright state. First, as shown in FIG. 16A, at the beginning of the return from the horizontal inverted state to the upright state, the droplets attached to the back surface of the convex lip portion are in contact with the back surface and the side surface of the nozzle portion. It remains due to the surface tension of the part. Next, as shown in FIG. 16B, when returning to the upright state, the liquid droplet does not return into the container and remains on the back surface of the convex lip portion. As shown in FIG. 16 (c), when the container is returned to an upright state (when the gravity of the droplet is greater than the sum of the upward forces on the surface tension on the droplet), the droplet is further It will hang down.

In the present embodiment, since the residual liquid preventing passage is used, the liquid droplet can be easily drawn into the container, and thus dripping can be prevented.
