JP4441787B2 - Solid agent application container - Google Patents

Description

  The present invention relates to a solid agent application container that contains a solid agent such as a solid anti-inflammatory analgesic.

  The application container of the anti-inflammatory analgesic can be conveniently applied by bending the upper part to form a so-called neck bend (Patent Document 1). However, such a bend-shaped applicator container is essentially unsuitable for containing a solid preparation, even if it is a liquid preparation. This is because the solid agent itself does not bend, so that it can be stored only in the neck portion of the application container, and the storage capacity is reduced, which is not practical.

In addition, as a container which accommodates a solid agent and draws out and uses a solid agent as needed, the container for well-known lipstick and the container for paste materials are proposed (for example, patent document 2). However, these containers are all straight and not bent.
Japanese Patent Laid-Open No. 50-38393 Japanese Patent Publication No.8-5502

  Therefore, in view of the actual situation of the prior art, an object of the present invention is to bend the neck by laying a receiving plate for hanging a bendable connecting plate with a screw tube on a tubular case having a curved portion. An object of the present invention is to provide an application container for a solid agent.

  In order to achieve this object, the configuration of the present invention includes a cylindrical case that connects an arcuate curved portion to an upper portion of a straight portion, a tray in a case that receives a solid agent that flows into the curved portion and solidifies, and a case And a knob with a screw shaft that is rotatably attached to the lower end of the plate. A connecting plate that can be bent along the curved portion is suspended from the saucer, and the screw shaft is attached to the straight portion under the saucer. The gist is to move up and down in the curved portion by rotating the knob and rotating the screw shaft forward and backward by rotating the knob and rotating the screw shaft forward and backward.

  The case has a circular cross section and a guide groove is formed on the inner surface on the side perpendicular to the bending direction of the curved portion, and both side edges of the connecting plate can be slidably fitted into the guide groove, or The cross section is elliptical, and the curved portion can be curved in the short axis direction of the case.

  Further, a fixing piece for fixing the solid agent may protrude from the upper surface of the tray, and the tray may be integrally formed with a connecting plate with a screw cylinder.

  According to such a configuration of the invention, the tray is housed in a neck-shaped case that connects the straight portion and the curved portion, and can receive a solid agent that flows into the curved portion and solidifies. However, when the raw material of the solid agent is poured, the tray is positioned near the lower end of the curved portion via the screw shaft, and slidably contacts the inner surface of the case over the entire circumference to form a seal against the raw material of the solid agent. Shall. On the other hand, when using the solidified solid agent, rotate the knob to rotate the screw shaft and drive the saucer upward, so that the solid agent in the curved part protrudes from the tip of the curved part and is applied to the affected part can do. This is because the screw shaft is housed in the straight portion at the bottom of the case and is screwed into the screw cylinder of the connecting plate integral with the saucer, and the connecting plate bends following the curved portion as the saucer rises. . In addition, in order to avoid the screw shaft which protrudes on a screw cylinder, an appropriate notch shall be provided in a connection plate. Moreover, if a knob is reversely rotated, a saucer will be lowered | hung through a screw axis | shaft and a solid agent can be accommodated again in a curved part.

  In the case of a circular cross section, the both ends of the coupling plate are slidably fitted into the guide groove on the inner surface, so that the tray does not rotate even if the screw shaft is rotated. In addition, since the case having an elliptical cross section restrains the inner tray so that it cannot rotate relative to the inner tray, it is not necessary to provide a special means for preventing the common rotation of the tray.

  If the solid agent fixing piece is provided on the upper surface of the saucer, there is no possibility that the solid agent is inadvertently separated from the saucer when the saucer is lowered and the solid agent is re-stored in the curved portion.

  The saucer can be easily formed integrally with a connecting plate with a screw cylinder by a plastic material having appropriate flexibility. Note that it is preferable to use, for example, low-density polyethylene as the plastic material in consideration of the sealing performance of the tray with respect to the inner surface of the case and the flexibility of the connecting plate.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The solid agent application container includes a cylindrical case 11, a tray 21 in the case 11, and a knob 31 at the lower end of the case 11 (FIG. 1). However, FIGS. 1A and 1B are respectively a partially broken entire front view and a partially broken entire side view.

  The case 11 has a circular cross section, and is formed by smoothly connecting a lower straight portion A and an upper arcuate curved portion B. A screw-type cap 12 is detachably attached to the upper end of the case 11 via a male screw 11b, and a pair of opposing surfaces of the inner surface of the case 11 is arranged on the side perpendicular to the bending direction of the bending portion B. Guide grooves 11 a and 11 a are formed over the entire length of the case 11. However, in FIGS. 1A and 1B, only one guide groove 11a is shown.

  The tray 21 is accommodated in the case 11 so as to be movable up and down in the axial direction of the case 11. The outer periphery of the upper end of the peripheral edge of the tray 21 is in sliding contact with the inner surface of the case 11 over the entire periphery, and forms a watertight seal with the inner surface of the case 11.

  A pair of blade-like fixing pieces 22 and 22 that face each other are provided in the tray 21 (FIGS. 1 and 2). The fixing pieces 22 and 22 are curved in the circumferential direction of the tray 21 and curved so as to face each other, and are smoothly thinned upward. Each fixing piece 22 has a length of about ¼ circumference in the circumferential direction of the tray 21 and is formed lower than the depth of the tray 21.

  A connecting plate 23 for attaching a screw cylinder 24 to the lower portion is suspended from the tray 21. The connecting plate 23 has a large open top notch 23 a under the tray 21, and the upper left and right ends are continuous from the bottom surface of the tray 21 to the oblique peripheral edge to the upper end of the tray 21. Note that the left and right side edges of the connecting plate 23 are slidably fitted into the guide grooves 11 a and 11 a on the inner surface of the case 11. In addition, the screw cylinder 24 is formed in the vertical direction coaxially with the tray 21 in the central portion of the lower portion of the connecting plate 23. The tray 21, the fixing pieces 22, 22, the connecting plate 23, and the screw cylinder 24 are integrally formed of, for example, low-density polyethylene. Therefore, the connecting plate 23 can be bent along the curved portion B of the case 11. The upper end of the connecting plate 23 is formed with seal portions 23b, 23b protruding in the radial direction on both sides of the tray 21 in order to form a watertight seal with the guide grooves 11a, 11a on the case 11 side. Yes.

  The knob 31 is formed in two upper and lower stages. The lower large-diameter portion of the knob 31 is formed to have substantially the same diameter as the outer diameter of the case 11, and an anti-slip knurling is engraved on the outer periphery. Further, an engagement rib 31a protruding in the circumferential direction is formed at the outer peripheral upper end of the upper small diameter portion, and the knob 31 is engaged with the engagement rib 31a beyond the engagement rib 11c on the inner surface of the lower end portion of the case 11. By fitting in the groove 11d, the case 11 is rotatably mounted on the lower end. A screw shaft 32 is erected on the upper surface of the knob 31, and the screw shaft 32 is screwed into the female screw 24 a of the screw cylinder 24. The male screw on the screw shaft 32 is a double thread, and the screw thread is cut through two parallel planes on both sides of the screw shaft 32 (FIGS. 1 and 3). The screw shaft 32 extends to the vicinity of the upper end of the straight portion A of the case 11.

  The tray 21 can be moved up and down in the curved portion B of the case 11 by rotating the knob 31 and rotating the screw shaft 32 forward and backward. Note that the lower limit of the tray 21 is defined by the lower ends of the connecting plate 23 and the screw cylinder 24 being in contact with the upper surface of the knob 31 (FIG. 1). At this time, the tray 21 is the lower end of the curved portion B of the case 11. Located in the vicinity. Further, the connecting plate 23 is curved along the curved portion B as the tray 21 rises in the curved portion B.

  Therefore, when the receiving tray 21 is placed at the lower limit, the cap 12 is removed, and the raw material of the solid agent is poured into the curved portion B of the case 11 to be solidified, the solid agent in the curved portion B can be received by the receiving tray 21. In addition, when pouring the raw material of a solid agent, the upper end of the curved part B shall be kept substantially horizontal.

  When the solid agent in the case 11 is used, the cap 12 is removed, the receiving tray 21 is raised into the curved portion B, and the tip of the solid agent is protruded from the tip of the curved portion B (two-dot chain line in FIG. 4). Further, when the tray 21 is lowered via the knob 31 and the screw shaft 32, the solid agent can be re-stored in the curved portion B and the cap 12 can be remounted. The fixing pieces 22 and 22 in the tray 21 are embedded in the lower end of the solid agent, and fix the solid agent to the tray 21. Therefore, when the solid agent is re-stored in the curved portion B, there is no possibility that the solid agent is separated from the tray 21.
