Description

  The present invention relates to an application container for applying a drug solution such as an anti-inflammatory analgesic (for example, a drug solution having general properties and a high-viscosity drug solution such as an ointment or cream, the same applies hereinafter).

  An application container that can be conveniently used for a large-area application site has been proposed (for example, Patent Document 1).

  A conventional application container has a lower cap attached to the mouth of a container body that stores a chemical solution, and an upper cap is connected to the upper portion of the lower cap so as to be relatively rotatable. An open-cell sponge material application member is housed and a cover for protecting the application member is provided. A middle cylinder with a lateral communication hole communicating with the container body is formed upward at the upper portion of the lower cap, and an outflow hole opening at the back of the socket portion is formed at the upper cap. Therefore, by rotating the upper cap forward and backward relative to the lower cap, the upper cap-side outflow hole faces the lower cap-side communication hole and the closed position where the outflow hole comes out of the communication hole. By switching the upper cap to the open position, the chemical solution can be applied through the application member. In addition, the application member can be formed in a large horizontally long shape, and the application work for a large-area application site can be made comfortable.

JP 2014-1008 A

  According to such a conventional technique, there is a problem that the switching operation is complicated because the upper cap is rotated relative to the lower cap to switch between the open position and the closed position. In addition, since the application member is a sponge material, a dedicated holder is indispensable. Combined with the use of an upper cap and a lower cap that can rotate relative to each other, the number of parts increases and the overall configuration becomes complicated. There was also a problem of being prone.

  Therefore, in view of the problems of the prior art, the object of the present invention is to improve the usability and to simplify the overall configuration by reducing the number of parts by combining a molded article application body, an adapter, and a cover. An object of the present invention is to provide a coating container that can be used.

  In order to achieve the above object, the structure of the present invention includes a container main body that stores a chemical solution, an adapter that is attached to a mouth portion of the container main body, a molded product application body that is stored in the socket portion of the adapter, and a front surface of the socket portion. The adapter is formed with an outflow hole for the chemical solution communicating with the container body at the back of the socket, and the application body is exposed to the front surface of the socket, and the application surface It has a guide part on the back and left and right guide bosses that engage with the oblique back wall of the socket part and make the plug part at the rear end of the guide part directly face the outflow hole. When the cover is attached, it is pushed into the socket part. The gist is to close the outflow hole through the stopper.

  In addition, the application body may be relatively movable back and forth by a predetermined stroke in the socket portion, and the engagement protrusion formed on the guide portion is engaged with the engagement rib on the inner surface of the socket portion to define the stroke. Alternatively, a gap for outflow of the chemical solution may be formed between the inner surface of the front end portion of the socket portion over the entire circumference of the application surface.

  According to the configuration of the invention, the application body is a molded product integrally formed of a soft resin material and is not a sponge material, so there is no need to use a dedicated holder, and the outlet hole of the adapter is fitted with a cover in the socket part. By doing so, it can be automatically closed via the plug at the rear end of the guide part of the application body, the overall configuration is simplified by minimizing the number of parts as a whole, and complicated switching operations are eliminated. Usability at the time of use can be improved. In addition to the smooth and glossy coating surface of the molded product, the matte pear ground and corrugated shape can be used to easily achieve the desired touch, compared to sponge materials. There is an advantage that it is hard to get dirty.

  The left and right guide bosses formed on the application body engage with the oblique inner wall of the socket when the cover is installed, align the position of the application body in the socket, align the plug with the outflow hole, and attach the cover At the same time, the outflow hole can be automatically and reliably closed through the plug.

  When the cover is attached, the applicator body that is relatively movable back and forth in the socket part is pushed into the socket part to the retreat limit and closes the outflow hole through the plug part. Advancing to open the outflow hole and forming an appropriate gap with the inner surface of the socket portion, the chemical solution from the outflow hole can flow out around the application surface. Therefore, if the application surface is brought into contact with the application site and moved back and forth and left and right, the chemical solution can be applied smoothly to the surface of the application site.

  The engaging protrusion formed on the guide portion of the application body engages with the engagement rib on the inner surface of the socket portion from the rear side to define the advance limit of the application body and can prevent the application body from coming off. However, when the application body is housed in the socket portion, the engagement protrusions cross the engagement rib from the front side to the rear side.

  An application body that forms a gap on the entire circumference of the application surface can always achieve good application performance without the amount of outflow of the chemical solution changing significantly depending on the moving direction of the application body at the application site. However, the gap at this time is preferably substantially uniform over the entire circumference of the application surface.

A joint portion 21a is formed. Further, axial guide ribs 21b, 21b,... Corresponding to the guide ribs 15, 15,... On the mouth portion 12 side are formed on the inner surface of the main body 21 (FIGS. 2A and 3A). The guide ribs 21b, 21b... Are formed at eight equal intervals at intervals corresponding to the width of the guide rib 15. Therefore, the adapter 20 can be connected to the mouth portion 12 so as to cover the body portion 21 over the mouth portion 12 in a watertight manner and not to be relatively rotatable. However, FIG. 3A is a cross-sectional view taken along the line X2-X2 in FIG. 2A, and FIGS. 3B and 3C are FIGS. FIG.

  The socket portion 22 of the adapter 20 is configured by forming a horizontally long opening forward at the tip of a flat plate-like support portion integrated with the main body portion 21 (FIGS. 1 and 2). The inside of the socket part 22 is formed in a hollow shape that can accommodate the application body 30, and a chemical solution outflow hole 24 is formed in the back part of the socket part 22. The outflow hole 24 communicates with the trunk portion 11 of the container main body 10 through the main body portion 21 and the mouth portion 12.

  The application body 30 is formed of a resin material such as LDPE or LLDPE, or a metal material such as aluminum, and has a flat plate shape behind the application surface 31 that fits the opening of the socket portion 22 of the adapter 20. A guide portion 32 is provided. The guide portion 32 can be stored in a flat plate-like support portion of the socket portion 22, and a plug portion 33 for closing the outflow hole 24 and left and right guide bosses 34, 34 are formed at the rear end of the guide portion 32. ing. In addition, rectangular engaging projections 35 and 35 are respectively formed on the upper and lower surfaces of the guide portion 32 so as to be arranged in a straight line in the lateral direction.

  The cover 40 is a lid that is detachably mounted so as to cover the front surface of the opening of the socket portion 22 of the adapter 20. An operation claw portion 41 is formed on each of the upper side and the lower side of the horizontally long cover 40, and a horizontally long linear protrusion 42 is formed on the inner top surface of the cover 40. Therefore, the cover 40 accommodates the applicator 30 in the socket portion 22, and when the inner surface of both ends is elastically engaged with both ends of the opening of the socket portion 22 from the outside and attached to the front surface of the socket portion 22, The application body 30 can be pushed into the socket portion 22 through the strip 42 and positioned, and the outflow hole 24 can be closed through the plug portion 33 of the application body 30 (FIGS. 2 and 3B). At this time, the guide bosses 34, 34 of the application body 30 are respectively engaged in the middle of the oblique rear wall of the socket portion 22 to adjust the posture of the application body 30 (FIGS. 2B and 3C). )), The plug portion 33 can be directly opposed to the outflow hole 24.

  On the other hand, the application body 30 in the socket portion 22 is prevented from coming off by engaging the engagement protrusions 35, 35... On both surfaces of the guide portion 32 with the corresponding engagement ribs 25 on the inner surface of the support portion of the socket portion 22, respectively. (FIG. 4). However, the application body 30 is relatively movable back and forth within the socket portion 22 by a stroke d corresponding to the distance between the engagement protrusions 35 and the engagement ribs 25. Further, when the application body 30 is pushed into the inner part of the socket part 22 via the cover 40, the application body 30 is substantially uniform between the entire circumference of the application surface 31 and the front end inner surface of the opening part of the socket part 22. A gap a can be formed. In addition, the coating surface 31 has a peripheral edge of the four circumferences smoothly bulging toward the central flat portion (FIGS. 2 and 4), and the upper and lower steps on the socket portion 22 side are provided on the rear surface side of the coating surface 31. Upper and lower chemical reservoirs b and b are formed via the ribs 31a along the four circumferences of the rear surfaces of the application surfaces 31 (FIGS. 1 and 4).

  When the cover 40 is removed to expose the application body 30 in the socket part 22 (FIG. 5), the application body 30 can move back and forth in the socket part 22 within a predetermined stroke d in FIG. In the forward limit, the plug portion 33 opens the outflow hole 24 (FIGS. 5B and 5C), and the left and right guide bosses 34 and 34 are separated from the oblique rear wall of the socket portion 22 (FIG. 5). 5 (B), (D)). An inclined tapered surface 24a is formed at the front end of the outflow hole 24 to guide and seat the plug portion 33 (FIG. 5C). However, FIGS. 5A and 5B are a longitudinal sectional view corresponding to FIG. 2A and a sectional view corresponding to the line X1-X1 in FIG. 5A, respectively. (D) is the principal part enlarged view of the same figure (A) and (B), respectively.

  In addition, even if the application body 30 in the socket part 22 may be inclined to one side in the longitudinal direction (FIG. 6), the cover 40 is attached to the front surface of the opening part of the socket part 22 to apply the application body. By pushing 30 into the socket portion 22, the left and right guide bosses 34, 34 are engaged with the oblique inner wall of the socket portion 22, and the outflow hole 24 can be correctly resealed via the plug portion 33 ( FIG. 2, FIG. 3 (B), (C)). Further, the lateral deviation of the application body 30 is corrected by the plug portion 33 being correctly opposed to the outflow hole 24 through the tapered surface 24a. 6A to 6D are diagrams corresponding to FIGS. 5A to 5D, respectively.

  Therefore, the application container stores the chemical L in the container body 10, removes the cover 40, and holds the socket portion 22 and the application body 30 of the adapter 20 downward (FIG. 7A), and the container body as necessary. When the 10 body parts 11 are pressed and deformed, the application body 30 in the socket part 22 moves to the forward limit and the outflow hole 24 is opened. Accordingly, the chemical liquid L from the container body 10 flows out to the spaces c and c including the respective chemical liquid reservoirs b on the rear surface side of the application surface 31 of the application body 30 through the outflow hole 24 (in the direction of the arrow in FIG. 7A). Further, it flows out to the outside through the gaps a around the four sides of the application surface 31 (in the direction of the arrow in FIG. 5B). However, FIGS. 7A and 7B are a longitudinal sectional view showing a use state, respectively, and an enlarged view of a main part of FIG. 7A.

  Therefore, after that, when the application surface 31 of the application body 30 of the application container is lightly pressed against the skin S of the application site and moved along the skin S (in the direction of the arrow in FIG. 8A), the gaps on the four circumferences of the application surface 31 The chemical liquid L from a flows out on the skin S and spreads, and the chemical liquid L can be smoothly applied onto the skin S (in the direction of the arrow in FIG. 8B). In addition, when the chemical solution L is applied onto the skin S in this way, the application body 30 moves backward from the advance limit by a distance d1 ≦ d. 8A and 8B are diagrams corresponding to FIGS. 7A and 7B, respectively.
