  According to the present invention, if the puncture needle is moved in the cylindrical body and punctured into the sealing body, the liquid in the container can be sprayed from the spray port communicating with the liquid flow path of the puncture needle. Thus, there is no need to transfer the liquid to a separately prepared spray container, and the inner solution can be kept in a sealed state until just before use, so that the risk of contamination can be reduced. Further, since the continuation body between the inside of the container and the spray port can be shut off by pulling the puncture needle out of the sealing body even before or after puncturing the sealing body with the puncture needle, the spray body is mistakenly sprayed. And liquid leakage from the spray port can be prevented.

  Embodiments of a spray container according to the present invention will be described below with reference to FIGS. In all the drawings and all the embodiments, the same components are denoted by the same reference numerals.

  As shown in FIGS. 1 and 2, the spray container 1 includes a container body 3 including a container mouth 2 sealed with a sealing body 2 a and a spray head 4 attached to the container mouth 2. . In the example shown in FIGS. 1 and 2, the sealing body 2 a is formed of a rubber material, but may be formed of a plastic thin film having no elasticity.

  The spray head 4 has a cylindrical body 5 that is tightly fixed to the container mouth portion 2 of the container body 3, a liquid flow passage 6 inside, a pointed end 7 at one end, and a puncture of the sealing body 2 a by the pointed end 7. A puncture needle 8 that is movably supported inside the cylindrical body 5 and a spray port 9 that is provided at the other end of the puncture needle 8 and communicates with the liquid flow path 6 are provided.

  The puncture needle 8 is provided with a guide holding means for guiding the puncture needle 8 so as to be movable along the direction of the central axis of the cylindrical body 5. In the illustrated example, the guide holding means includes a cylindrical inner cylinder portion 11 that slidably contacts the inner peripheral surface of the cylindrical body 5, and a cap shape that slidably contacts the outer peripheral surface of the cylindrical body 5. The outer cylinder part 12 which carried out and the rubber | gum O-ring 13 fitted by the ditch | groove formed in the outer peripheral surface of the inner cylinder part 11 are comprised. The O-ring 13 also contributes to airtightness.

  The cylindrical body 5 can be provided with a flange 14 on its outer peripheral surface and a step 15 on its inner peripheral surface. The inner peripheral surface of the cylindrical body 5 is divided into a large-diameter inner peripheral surface and a small-diameter inner peripheral surface by a step portion 15 on the inner peripheral surface. The inner cylindrical portion 11 of the puncture needle 8 includes a main body portion having an outer diameter capable of sliding contact with a small-diameter inner peripheral surface of the cylindrical body 5, and a small-diameter inner peripheral surface of the cylindrical body 5 at the end of the main body portion. And a slightly larger diameter flange portion 16. The collar part 14 of the cylindrical body 5 can receive the end surface 12 a of the outer cylinder part 12 of the puncture needle 8, and the step part 15 of the cylindrical body 5 can receive the collar part 16 of the inner cylinder part 11. (Refer to the enlarged portions of FIGS. 1 and 2).

  The cylindrical body 5 can be fixed to the container mouth 2 by a known method, and the fixing method is not particularly limited, such as fitting, screwing, and welding. The cylindrical body 5 may be detachably fixed to the container mouth portion 2. If the cylindrical body 5 is detachably fixed to the container mouth portion 2, the spray head 4 and the container body 3 can be separated and discarded.

  It is preferable that the cylindrical body 5 and the puncture needle 8 include a first engagement element and a second engagement element that are engaged with each other. The first engaging element is engaged so as to maintain a state (state shown in FIG. 1) in which the puncture needle 8 is held by the cylindrical body at a position separated from the sealing body 2a by a predetermined distance. The second engagement element keeps the state where the puncture needle 8 moves in the cylindrical body 5 to puncture the sealing body 2a and is held by the cylindrical body 5 at a predetermined position (the state shown in FIG. 2). Engage. When the second engagement element is engaged, the outer cylinder portion 12 comes into contact with the flange portion 14 of the cylindrical body 5, and the flange portion 16 of the inner cylinder portion 11 comes into contact with the step portion 15 of the cylindrical body 5. Designed to.

  The first engaging element is formed at a predetermined position on the outer peripheral surface of the flange portion 16 of the inner cylindrical portion 11 and at a predetermined position on the inner peripheral surface of the cylindrical body 5 and is engaged with the convex portion 17. The second engaging element is formed by a convex portion 17 and a second concave portion 19 that is formed at a predetermined position on the inner peripheral surface of the cylindrical body 5 and engages with the convex portion 17. And is composed of. The first engagement element and the second engagement element are formed so that the degree of protrusion of the convex part 17 and the degree of depression of the concave parts 18 and 19 are small so that both can be engaged and disengaged. The first engagement element and the second engagement element are not limited to the illustrated examples, and various types of engagement elements can be employed. When the puncture needle 8 is located at the engagement position of the second engagement element, the puncture needle 8 penetrates the sealing body 2a, and the liquid flow path 6 of the puncture needle 8 enters the container body 3 in the container body 3. It can be ensured that the liquid flows.

  The first engagement element is easily disengaged from the engagement position in the direction in which the puncture needle 8 approaches the sealing body 2a, and in the opposite direction, that is, in the direction in which the puncture needle 8 is separated from the sealing body 2a. Is preferably configured to be difficult to disengage. Specifically, for example, as shown in FIG. 3, regarding the shape of the first recess 18 to be engaged, one wall 18 a of the opposing groove inner walls that form the first recess 18 is connected to the other. By projecting from the wall 18b, the engagement strength can be changed depending on the direction in which the engagement is disengaged. In this way, it is possible to prevent the puncture needle 8 from being detached from the cylindrical body 5 by making it difficult for the puncture needle 8 to be disengaged in the direction away from the sealing body 2a.

  The puncture needle 8 is formed so that the opening 2 of the liquid flow passage 6 is located in the container body 2 and in the vicinity of the sealing body 2a when the second engagement element is engaged. As will be described later, since the spray container 1 of the present invention is in an inverted state during use, the residual liquid in the container body 2 is reduced as much as possible after use, and as much liquid as possible can be sprayed. is there. Therefore, when the opening 2 is opened at the tip 7 of the puncture needle 8 (in the case of FIGS. 1 and 2), the puncture needle 8 is long enough to penetrate the sealing body 2a and should be as short as possible. Therefore, it is preferable to make the spray head 4 compact. That is, it is preferable that the puncture needle 8 is set to such a length that the pointed end penetrates the sealing body 2a and the pointed end can only be inserted to a position near the sealing body. In addition, as shown in FIG. 4, the liquid flow path 6 can also form the opening part 2 in the side surface in the vicinity of the tip 7 of the puncture needle 8A, and in this case, the puncture needle 8 having the opening 2 formed at the tip. The puncture needle 8 'can also be made slightly longer than in FIG.

  Moreover, the stand 20 which supports the container main body 3 in the inverted state which arrange | positions above the spray head 4 is provided in the spray head 4 (refer FIG. 5). The shape of the stand 20 is not particularly limited as long as the spray container 1 can be placed on a table or the like in an inverted state. For example, the stand 20 may have a cylindrical shape in addition to a plate shape.

  The spray head 4 can include a trigger 21. The trigger 21 may be a known one, and is connected to a piston pump (not shown) inside the spray head 4 in the same manner as a general spray. When the trigger 21 is pulled, liquid is passed through the puncture needle by a pumping action. The sucked liquid is blown out in a mist form from the spray port 9.

  It is preferable that the spray port 9 of the spray head 4 is oriented in a direction substantially perpendicular to the puncture needle 8. In addition, the spraying port 9 may be provided with a known switching mechanism in which the ejection state is switched to fog, shower, straight or the like by a rotation operation as necessary. Alternatively, the spray port 9 may be sealed with a peelable film to keep the sterilized state until use.

  The spray container 1 having the above configuration is used as follows. First, from the state shown in FIG. 1, the spray head 4 is pressed from above and the puncture needle is moved downward to establish the communication state shown in FIG. 2, and then the top and bottom are reversed. Then, as shown in FIG. 6, the cylindrical body 5 is held by hand, the trigger 21 is pulled, and the content liquid is sprayed from the spray port 9. Thus, when the container body 3 is inverted and sprayed, the remaining amount of the internal solution in the container body 3 can be easily determined.

  Here, a known spray head that does not include an air intake port (not shown) may be employed as the spray head. This type of spray head is disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-111472 and Japanese Patent Application Laid-Open No. 2000-255552, and does not introduce outside air, so that a container filled with a liquid to be sprayed (usually without voids) is flexible. The flexible container is configured such that the container is deformed so as to reduce its internal volume as the liquid in the container is reduced by spraying. Therefore, if such a spray head without an air intake is used, the spray container is in a state in which the opening of the puncture needle is immersed in the liquid regardless of the positional relationship between the spray head and the container body. Therefore, spraying is possible not only in the inverted state but also in any posture.

  In the above-described embodiment, the form including the first engagement element and the second engagement element has been described. However, an embodiment in which the first engagement element and the second engagement element are not provided may be employed.

  When the first engagement element is not provided, it is preferable to provide a retaining mechanism that prevents the puncture needle from being pulled out of the cylindrical body. As such a retaining mechanism, various mechanisms can be employed. For example, as shown in FIG. 7, a flange 51 protruding inward is formed at the end of the cylindrical body 5 of the spray head 4A. The puncture needle 8 can be prevented from coming out of the cylindrical body 5 by the end of the inner cylindrical portion 11 coming into contact with the flange 51.

  When the second engagement element is not provided, if the puncture needle 8 is punctured into the sealing body 2a, the puncture needle 8 is held through the sealing body 2a by the elastic force of the sealing body 2a. be able to.

  Next, still another embodiment of the spray head according to the present invention will be described below with reference to FIGS.
