 Nozzle device and liquid supply method

 Technical field

 The present invention relates to a nozzle device and a supply method for supplying a liquid to a bottomed cylindrical container, and also supplies a transpiration agent to be solidified later to the transpiration container in a liquid state. The present invention relates to a nozzle device that can be advantageously used.

 Background art

 [0002] As a transpiration apparatus using a solid transpiration agent, for example, there is an apparatus as shown in FIG. In this transpiration apparatus, solid medicine A is accommodated in a transpiration container 100. The transpiration container 100 includes a support 110 in which a cylindrical support column 112 is erected at the center of a dish-shaped member 111, and a cylindrical cover 120 that forms a medicine containing space between the support column 112 and The upper column 130 is fitted to the support column 112 so that the vertical position can be adjusted, and the coupling member 140 that couples the upper column and the upper end of the cover 120 to each other. The container 100 has a double structure of the support 110. That is, the support 110 includes: i) a base 110a including a dish-shaped member 111 and an inner column 112a that is integrally formed with the dish-shaped member 111 and extends upward; and ii) is detachably fitted into the dish-shaped member 111. An attaching / detaching portion 110b including an inner fitting portion 11lb and an outer support 112b formed integrally therewith and extending upward is provided. The detachable portion 110b is placed on the base 110a from above. The support strut 112 includes an inner strut 112a and an outer strut 112b having a slightly larger diameter. One or both of the columns is provided with a rib extending in the longitudinal direction, and the upper column 130 is stationary at an arbitrary position in the vertical direction with respect to the support column 112 by contacting with a pressure that tightens the rib. It has become possible to make it.

[0003] In use of this transpiration device, when the cover 120 is lifted during use, the coupling member 140 and the upper support column 130 rise together with this, and form a transpiration gap for the drug between the dish-shaped member 111. . Therefore, the volatilization amount of the medicine can be adjusted by adjusting the opening degree of the gap using the stationary action of the upper support 130 with respect to the support support 112. An example of such a transpiration apparatus is described in Document 1. [0004] To manufacture this transpiration apparatus, first, the support 110 is formed by covering the base 110a with the detachable part 110b. The cover 120 is also covered with an upward force, and the lower end 140e is liquid-tightly fitted to the upper end 1 lie of the dish-like member 111. The upper end of the cover 120 is left open without attaching the coupling member 140. Then, the container in this state is sent to the drug supply line to supply the drug.

 [0005] As a medicine supply device in the supply line, an apparatus for sequentially supplying medicines to a container from a discharge port connected to a supply source via a nozzle is used. When the container reaches the supply point, the nozzle is inserted from the upper end opening of the cover 120 and the medicine is supplied. Drugs generally contain water, gelling agents, fragrances, surfactants, salts, and the like as components, and become solid at room temperature, but become liquid by heating when supplied.

 [0006] On the other hand, the above-mentioned upper support 130 is previously connected to the connecting member 140, and when the supply of the medicine and the cooling and solidification are finished, the upper support 130 is inserted from the opening of the cover 120 to the support support 112. It is inserted and the coupling member 140 is fitted into the opening of the cover 120 to complete the main structure of the container. In the subsequent process, cooling, packaging with film, etc. are performed to complete the transpiration apparatus.

 An example of a conventional nozzle used in such a process is shown in FIGS. Fig. 7 shows the right side of the center line as viewed from the front, and the left side of the center line as a cross section passing through the center line. FIG. 8 is a bottom view of the nozzle. The nozzle 200 includes a mounting cylinder 201 for mounting on the discharge port of the medicine supply device, a bottom wall 202 covering the lower end of the mounting cylinder, an inner diameter smaller than that of the mounting cylinder 201, and downward from the bottom wall. And a guide part 204 extending downward from the discharge cylinder 203 from the central portion of the bottom wall 202. On the upper inner surface of the mounting cylinder 201, a female screw part 201a for being screwed into the discharge port of the medicine supply device is provided. In the bottom wall 202 and the discharge cylinder 203, a large number of through holes 203a extending from the upper surface of the bottom wall 202 to the lower end of the discharge cylinder extend linearly. Further, the guide portion 204 includes a centering portion 204a that is tapered so as to be engaged with the upper end portion of the upper column 130 of the transpiration container when the nozzle is inserted.

The nozzle 200 is used as shown in FIG. 9 when supplying a medicine to a container. The nozzle 200 is connected to the discharge port 302 of the medicine supply device by screwing the mounting cylinder 201. It is. In the supply line, the transpiration container 100 is lifted by the carrier 301 when it reaches the supply point. When the transpiration container 100 is raised, the nozzle 200 moves the centering part 204a of the guide part 204 into the upper end of the support column 112 (inner column 112a) of the transpiration container, positions the container, and discharges it. Position the tube 203 so that it surrounds the top of the outer post 112b. Then, the liquid medicine A1 is supplied from the discharge port 302 through the nozzle 200 into the container. At this time, the liquid medicine A1 is discharged downward from the through-hole 203a and flows downward along the outer support 112b as shown by the arrows (FIG. 9 shows the enlarged layer thickness of the medicine A1 flow). ). Then, as the supply proceeds, the liquid level of the drug gradually rises, and when the predetermined amount is filled, the supply is stopped and the transport table 301 is lowered. After that, it goes through various processes such as a cooling process.

 [0009] In the example shown in the figure, the different drug AO (deodorant) is supplied in the same manner as described above and cooled and solidified, and then the aforementioned drug A1 (fragrance) is supplied. In the end, it becomes solid drug A by both drugs.

 Disclosure of the invention

 Problems to be solved by the invention

 [0010] According to the nozzle 200, the liquid medicine A1, which is discharged from the numerous through holes 203a and falls along the peripheral surface of the outer support column 112b, entrains air and sinks below the liquid level when reaching the liquid level. Tend. As a result, air bubbles are mixed in the supplied medicine. Many of these bubbles rise and disappear after a period of time for defoaming, but may remain to some extent. The remaining foam remains as a small void in the solidified drug A, and the appearance is impaired.

[0011] In addition, when supplying liquid to bottomed cylindrical containers such as bottles and cans of various shapes, it is most preferable to inject the liquid downward from the discharge port of the liquid supply device. Since it is simple and it is easy to increase the supply speed, the nozzle device generally has a discharge port directed downward. However, according to this nozzle device, as described above, the discharged liquid entrains the air and sinks under the surface of the liquid, causing problems such as air mixing and generation of bubbles, and quality deterioration and appearance deterioration associated therewith. May occur. The present invention solves these problems of the prior art and eliminates the entrainment of air when supplying a liquid to a bottomed cylindrical container, or a nozzle device and a supply method that can be suppressed to a level that does not cause a problem. The purpose is to provide.

 Means for solving the problem

 In order to achieve the above object, the present invention provides a nozzle device for supplying a liquid to a bottomed cylindrical container, a mounting cylinder for mounting on a discharge port of the liquid supply device, and the mounting A bottom wall covering the lower end of the cylinder; and a discharge cylinder extending downward from the bottom wall. The bottom wall and the discharge cylinder extend from the upper surface of the bottom wall into the side wall of the discharge cylinder, and the lower end extends into the side wall. The nozzle device is characterized in that a large number of introduction holes are formed, and a discharge groove is formed in the discharge cylinder so as to open to the outer peripheral surface and communicate with the introduction hole.

 [0014] In order to achieve the above object, the present invention also provides a medicine storage space between a support body in which a cylindrical support column is erected at the center of a dish-shaped member and the support column, and the dish A nozzle device for supplying a liquid medicine before solidification to a bottomed cylindrical container composed of a cylindrical cover that is detachably coupled onto a cylindrical member, and a medicine discharge port in the medicine supply device A mounting cylinder, a bottom wall covering a lower end of the mounting cylinder, a discharge cylinder extending downward from the bottom wall, and a guide portion extending downward from the discharge cylinder from a central portion of the bottom wall. The bottom wall and the discharge cylinder are formed with a number of introduction holes extending from the upper surface of the bottom wall into the side wall of the discharge cylinder and having a lower end staying in the side wall. And a discharge groove communicating with the introduction hole is formed inside the guide portion. Also provided is a nozzle device comprising a centering portion tapered at the lower end of the central portion so as to be engaged with the upper end portion of the support column in the bottomed cylindrical container from which the bottom is removed. It is.

 In order to achieve the above object, the present invention is a method for supplying a liquid to a bottomed cylindrical container, wherein the liquid is discharged in a radial direction from a nozzle device attached to a discharge port of the liquid supply device. The present invention also provides a supply method characterized by bringing the liquid into contact with the side wall of the container and dropping the liquid along the side wall of the container.

 The invention's effect

In the nozzle device according to the present invention, the liquid is discharged from the discharge port of the liquid supply device to the mounting cylinder. The liquid is introduced into a number of introduction holes extending from the upper surface of the bottom wall of the mounting cylinder into the side wall of the discharge cylinder, and then discharged from a discharge groove communicating with the pore. Particularly, since the lower end of the introduction hole stays in the side wall of the discharge cylinder and the discharge groove opens on the outer peripheral surface of the discharge cylinder, the liquid is discharged in a radial direction from the outer peripheral surface. Therefore, the liquid can be brought into contact with the cylindrical side wall of the bottomed cylindrical container and dropped along the side wall. Note that the direction of the discharge groove on the outer peripheral surface of the discharge cylinder can be appropriately determined as necessary, such as a horizontal direction or a direction inclined upward or downward. Further, the discharge speed from the discharge groove is adjusted so that the liquid is brought into contact with the cylindrical side wall of the bottomed cylindrical container and dropped along the side wall without splashing after the contact. Is good.

 [0017] Since the cylindrical side wall defines an inner peripheral surface located outward in the radial direction of the container, the inner peripheral length thereof is large. Therefore, the speed of the liquid falling along the cylindrical side wall is much slower than the case of falling concentrated on the central part of the container. Thus, the falling liquid slowly reaches the liquid level, resulting in little or very little air entrainment. As a result, it is possible to eliminate problems such as air mixing in the liquid in the container, generation of bubbles, and the accompanying quality deterioration and appearance deterioration.

 [0018] Further, in the nozzle device for supplying the liquid medicine before solidification to the transpiration container, the same effect as the above effect can be obtained, and a cylindrical shape is formed in the central portion of the dish-shaped member. The shape of a bottomed cylindrical container comprising: a support body in which a support support column is erected; and a cylindrical cover that is detachably coupled to the dish-like member by forming a medicine storage space between the support support column The advantageous supply corresponding to is possible. That is, a guide portion that extends downward from the discharge tube from the center portion of the bottom wall, and the guide portion is a taper that is tapered to engage with the upper end portion of the support column in the bottomed cylindrical container. Since the discharge portion is provided at the lower end of the central portion, the liquid discharged in the radial direction from the discharge groove opened on the outer peripheral surface of the discharge cylinder is based on the positioning by the engagement between the centering portion and the support column. It can be brought into contact with the container side wall appropriately. In this way, the force S can reliably obtain a low-speed liquid flow along the side wall.

[0019] In particular, when the discharge groove is formed as an annular groove continuously extending along the outer peripheral surface of the discharge cylinder, the liquid is continuously connected from the discharge groove until reaching the container side wall. It can be a continuous film. Thus, it is advantageous to prevent the mixture of air into the liquid when the discharge liquid is in the form of a continuous film. That is, if the discharge liquid has a continuous film shape, the contact area with air is reduced and the total opening area of the discharge groove is increased, so that the discharge speed from the discharge groove can be reduced, and these problems can be solved. Can do. The discharge form in this case is most preferably a continuous film, but even if the continuity is interrupted in part, it is advantageous in preventing air from being mixed in since there are many continuous parts. However, it is also possible to form the discharge groove by openings intermittently arranged in the circumferential direction of the discharge cylinder 22, and in this case as well, if the openings are arranged close to each other, adjacent discharge liquids Connected in the middle to form a continuous film, the same effect as above can be obtained. In addition, by appropriately setting the shape and dimensions of each opening, it is possible to reduce the degree of turbulent flow when the discharged liquid comes into contact with the container side wall, thereby making it difficult to entrain air. Can do.

 In the liquid supply method according to the present invention, when supplying the liquid to the bottomed cylindrical container, the liquid is discharged in a radial direction from a nozzle device attached to the discharge port of the liquid supply apparatus. The liquid is caused to fall along the side wall of the container by contacting the side wall. Therefore, the liquid spreads on the inner peripheral surface of the container and slowly reaches the liquid surface, and as a result, there is no or very little air entrainment, and air in the liquid in the container and generation of bubbles are generated. It is possible to quickly eliminate this problem.

 [0021] In particular, in the above method, it is more advantageous to prevent air from being mixed into the liquid if the liquid discharged from the nozzle device in the radial direction is discharged as a continuous film.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same or similar parts in the drawings may be denoted by the same reference numerals and description thereof may be omitted. 1 and 2 are a front view and a bottom view, respectively, of a nozzle device 1 according to an embodiment of the present invention. The nozzle device 1 discharges and supplies a molten drug into the container in order to form the solid drug A accommodated in the transpiration container 100 shown in FIG.

As shown in FIG. 3, the nozzle device 1 is formed by combining the mounting cylinder 10 and the discharge unit 20 separately. The mounting cylinder 10 is composed of an annular body 11, and an upper female screw portion 12 is formed on the upper portion thereof to be screwed to the discharge port of the liquid supply device, and a discharge portion is formed on the lower portion thereof. A lower female thread portion 13 for screwing 20 may be formed, and a knurled surface may be provided.

 The discharge unit 20 includes a flat plate portion 21 that serves as a bottom wall of the mounting tube 10 and a discharge tube 22 that has an outer diameter and an inner diameter smaller than the mounting tube 10 and extends downward from the flat plate portion 21. The flat plate portion 21 and the discharge tube 22 are formed with a number of introduction holes 23 extending from the upper surface of the flat plate portion 21 into the side wall of the discharge tube 22 and having the lower ends remaining in the discharge tube 22. Further, the discharge cylinder 22 is formed with a discharge groove 24 that opens to the outer peripheral surface and communicates with the introduction hole 23 inside. In this embodiment, the discharge / groove 24 is formed as an annular groove extending along the outer peripheral surface of the discharge cylinder 22.

 A male screw portion 26 for screwing with the lower female screw portion 13 of the mounting cylinder 10 is formed on the peripheral portion of the flat plate portion 21. A guide portion 27 extends downward from the lower surface of the central portion of the flat plate portion 21. The guide portion 27 has a centering portion 27a tapered at the lower end of the central portion so as to be engaged with the upper end portion of the support column 112 in the container portion (bottomed tubular container) from which the cover 120 and the upper column 130 are removed. ing.

 [0026] The dimensions and drug characteristics of the main part of this nozzle device are as follows:

 Outer diameter of mounting cylinder 10 dl: 48mm

 Inside diameter of mounting cylinder 10 d2 (location in contact with flat plate part 21): 40 mm

 Outer diameter of discharge cylinder 22 d3: 34mm

 Inner diameter of discharge cylinder 22 d4: 24.5 mm

 Diameter and number of introduction holes 23: 1.5mm x 32

 Introduction hole 23 length: 20mm

 Width of ejection groove 24 (gap in the vertical direction): lmm

 Discharge groove 24 discharge direction: horizontal

 Distance from discharge groove 24 to cover side wall: 10.5mm

 Drug viscosity: 200-500cps

 Drug temperature: 57. 7-63. 7 ° C

 Drug discharge speed: 25m / min

As in this embodiment, in the nozzle device for supplying the container with the transpiration agent (heated and solidified later) in the heated and melted state, the diameter of the introduction hole; It is more desirable that the width of the introduction hole is about 1.5 mm and the width of the discharge groove is about 1 mm. If the diameter of the introduction hole and the width of the discharge groove are less than the above lower limit, clogging is likely to occur, or if a predetermined filling speed is obtained, the flow rate increases, resulting in a problem that foaming easily occurs. If it exceeds, the flow rate will be insufficient and the medicine will flow down without reaching the inner surface of the cover.

 [0027] As described above, the nozzle device is formed by combining the mounting cylinder 10 and the discharge unit 20, and as described below, each part can be easily processed. ing . That is, since the mounting cylinder 10 has an annular shape with the center portion penetrating vertically, the upper female screw portion 12 and the lower female screw portion 13 can be easily cut. Further, since the discharge portion 20 has the flat plate portion 21 exposed at the uppermost position, the length of the drill used when drilling the thin and deep introduction hole 23 is the length necessary for the drilling depth. This is advantageous for preventing damage to the drill. If the mounting cylinder 10 and the discharge part 20 are integrated, the drill for drilling the introduction hole 23 must have an extra length corresponding to the height of the mounting cylinder 10 and are prone to breakage. Become. Furthermore, since the discharge groove 24 is a continuous annular groove, cutting can be performed while the discharge portion 20 is rotated about its central axis, thereby easily forming the discharge groove 24 communicating with the introduction hole 23. Can be formed.

 The nozzle device 1 is used in the same manner as described above with reference to FIG. 9 when supplying a liquid (medicine) to a container. However, in the nozzle device 1, the lower end of the introduction hole 23 extending from the upper surface of the flat plate portion 21 into the side wall of the discharge cylinder 22 remains in the discharge cylinder 22, and the discharge cylinder 22 communicates with the introduction hole 23 internally. A discharge groove 24 opened on the outer peripheral surface is formed. Therefore, as shown in FIG. 4, the medicine A1 is ejected radially from the ejection groove 24, contacts the inner surface of the cover 120 of the container, and falls along the inner surface as shown by the arrow (in FIG. 4, the flow of the medicine A1 The layer thickness is enlarged). Therefore, the medicine A1 spreads on the inner surface of the cover 120 having a large area, slowly falls and reaches the liquid surface, and as a result, there is no or very little air entrainment. This prevents bubbles from being generated in the liquid in the container.

[0029] The dimensions of the introduction hole 23 and the discharge groove 24 suitable for preventing air entrainment are appropriately determined according to the viscosity of the medicine or liquid to be discharged, in addition to those described above. In addition, the distance from the discharge groove to the cover side wall is such that the discharged medicine or liquid jumps after reaching the cover side wall. It is set to fall along the cover side wall without splashing, and the bottom wall upper surface force of the nozzle device and the length of the introduction hole are determined so as to obtain such a position of the discharge groove.

[0030] The container filled with the drug is then solidified with the liquid drug in the cooling step, and the upper support column 130 and the coupling member 140 are attached, packaged with a film, and completed as a transpiration device.

 [0031] This transpiration device can replenish cartridge-type refilling chemicals when the chemicals are completely evaporated by use. This cartridge also has a bottomed cylindrical container filled with a medicine, and in the manufacturing process, the medicine is filled using the same nozzle device as described above. FIG. 5 shows the filling process. As shown in the figure, the refilling container 100 'has a cylindrical support column 112' standing upright at the center of the dish-shaped member 111 'and the lower end of the force bar 120' is joined to the peripheral edge of the dish-shaped member 111 '. It is a thing. The drug is filled between the column 112 ′ and the cover 120 ′ of the container 100 ′. Since the basic structure of the nozzle device 1 ′ is the same as that shown in FIGS.;! To 3, in FIG. 5, the corresponding part numbers are indicated by a dash (′). In addition, the action at the time of supplying the drug is the same, and as shown in the figure, the drug A1 is discharged radially from the discharge groove 24 ′ and comes into contact with the inner surface of the cover 120 ′, along the inner surface as shown by the arrow. It falls (Figure 5 shows an enlarged layer thickness of the drug A1 flow). As a result, the drug A1 slowly falls and reaches the liquid level, and there is no or very little air entrainment.

 This cartridge is mounted so that the cover 120, the coupling member 140, and the upper support 130 are integrally removed from the transpiration container 100 and covered from the support support 112. Accordingly, the dish-shaped member 111 of the cartridge is received by the dish-shaped member 111 of the transpiration container, and the support column 112 of the transpiration container is covered with the support column 112 'of the cartridge. If the cover 120, the coupling member 140, and the upper strut 130 of the transpiration container 100 are attached thereto, it can be used again.

[0033] The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the nozzle device can be integrally formed without being separated into the mounting cylinder 10 and the discharge section 20. Further, the nozzle device may be provided with a shape, a size, and the like necessary for supplying various liquids to the bottomed cylindrical container in addition to supplying the chemical to the transpiration container.
