Summary of the Invention

Problems to be Solved by the Invention

[0004] Such a container is usually provided with a cover cap so as to store the nozzle inside, and the cover cap protects the nozzle and is configured to prevent the content from leaking by bringing the inner wall surface into close contact with the pouring outlet at the tip of the nozzle. However, when the pouring outlet points obliquely upward as described above, a gap is likely to occur between the pouring outlet and the inner wall surface of the cover cap, and there is a problem in that the sealing performance is unstable.

[0005] Therefore, the present invention relates to a container with a pouring stopper capable of dripping and pouring out a liquid content from a pouring outlet directed obliquely upward, and an object thereof is to provide a container with a pouring stopper capable of improving the sealing property of the pouring outlet by a cover cap.

Means for Solving the Problems

[0006] The container with a pouring stopper of the present invention developed to achieve the above object is a container body for containing a content, a pouring stopper having a nozzle with a pouring outlet directed obliquely upward, and being detachably fitted and held to the mouth-neck portion of the container body, and a cover cap for storing the pouring stopper inside, and is a container with a pouring stopper capable of tilting the container body together with the pouring stopper to drip and pour out the content stored in the container body through the pouring outlet, wherein the pouring stopper has a passage leading to the pouring outlet of the nozzle, a body portion connected in an upright posture to the lower surface of its head, and a base connected to the lower end of the body portion and detachably attachable to the mouth-neck portion of the container body, and the cover cap is provided with an inner wall surface portion capable of closely contacting and sealing the pouring outlet of the nozzle in a state where the pouring stopper is stored inside, and capable of abutting against the rear end of the head, and an annular convex portion for supporting the nozzle and the head from their lower surfaces and stably maintaining the close contact posture of the pouring outlet with respect to the inner wall surface portion and the abutting posture at the rear end of the head. In the container with a pouring stopper of the present invention, it is preferable that the annular convex portion is a screw portion capable of screwing with the nozzle tip of the nozzle and the rear end of the head.

[0007] In the container with a pouring stopper of the present invention, it is preferable that the annular convex portion is a protrusion capable of undercut fitting with the nozzle tip of the nozzle and the rear end of the head.

[0008]

[0009] ​Furthermore, in the container with a pouring stopper of the present invention, it is preferable that the body portion has a thin-walled portion that can be elastically deformed when the head portion is pushed in.

Advantages of the Invention

[0010] According to the container with a pouring stopper of the present invention, when the cover cap is put on the pouring stopper and stored inside, the inner wall surface portion of the cover cap adheres closely to the pouring outlet of the nozzle, and the close contact posture is supported by the annular convex portion that abuts against the lower surface of the head portion of the nozzle and the pouring stopper, so that it can be stably maintained. Therefore, the pouring outlet of the nozzle can be reliably sealed.

[0011] Also, according to the present invention, when the annular convex portion is a threaded portion and the cover cap is put on the pouring stopper and rotated, the tip of the nozzle and the rear end of the head portion of the pouring stopper serve as threads, and by screwing with the annular convex portion, the cover cap can be reliably closed. At the same time, since the cover cap is held by both the nozzle and the rear end of the head portion, wobbling can be prevented.

[0012] Furthermore, according to the present invention, the pouring stopper has a passage leading to the pouring outlet of the nozzle, and by providing a thin-walled portion in the body portion that is connected to the lower surface of the head portion in an upright posture, when the rear end of the head portion is pushed, the thin-walled portion bends, thereby increasing the internal pressure in the body portion and allowing the contents to be poured out from the pouring outlet.

[0014] Embodiments of the present invention will be described with reference to the drawings. FIG. 1 schematically shows an embodiment of a container with a spout according to the present invention, which applies a double-thread as an annular convex portion. (a) is a plan view, and (b) is a view showing a cross section taken along line A-A of (a) (a cross section showing the upper part from the neck portion of the container body). FIG. 2 is a view showing the plane of the spout after removing the cover cap from the container with a spout shown in FIG. 1. FIG. 3 schematically shows another embodiment of a container with a spout according to the present invention, which applies a single-thread as an annular convex portion. FIG. 4 schematically shows yet another embodiment of a container with a spout according to the present invention, which applies a projection that can be undercut-fitted as an annular convex portion.

[0015] In FIGS. 1 to 4, reference numeral 1 denotes a container body for containing contents, reference numeral 2 denotes a spout attached to the neck portion 11 of the container body 1, and reference numeral 3 denotes a cover cap for storing the spout 2 inside.

[0016] The container body 1 has a filling space for the contents inside and is provided with a cylindrical neck portion 11 at the top. The container body 1 can be applied to various types such as a sample bottle made of a hard material such as glass and a squeeze bottle made of a synthetic resin material, and is not particularly limited. In addition, in the present embodiment, a cylindrical container body 1 is shown as an example, but the shape of the container body can be appropriately changed based on the type of contents, the design of the container, the use, etc., and is not limited to the illustrated shape.

[0017] The spout 2 is composed of a head portion 21, a body portion 23, and a base 24, and can be manufactured using a material such as synthetic resin, but the material of the material is not particularly limited.

[0018] The head 21 has a saddle-shaped configuration in plan view as shown in FIG. 2, and has a nozzle 22 formed with a spout 22a directed obliquely upward. When discharging the contents, by tilting the container body 1 in a direction such that the spout 22a faces downward, the contents in the container body 1 drip out from the spout 22a through a passage in the body portion 23 described later. Note that "drip out" means discharging the contents so that they flow down from the spout 22a with the container body 1 tilted, and in a state where the container body 1 is tilted, the contents can be discharged from the spout 22a by increasing the internal pressure of the container body 1 by pushing in the head 21 as described later, squeezing the container body 1, etc., and the method thereof is not particularly limited.

[0019] The body portion 23 has a cylindrical passage connected to the spout 22a of the nozzle 22 and is suspended from the lower surface of the head 21. A thin-walled portion 23a is provided at a lower position of the body portion 23. When discharging the contents, the thin-walled portion 23a bends when the rear end 21a of the head 21 is pressed with a finger from above in a state where the container body 1 is in a tilted posture, increasing the internal pressure in the body portion 23 and allowing the contents to drip out from the spout 22a. Note that the thin-walled portion 23a is preferably provided in a range of at least about half the circumference of the body portion 23 directly below the rear end 21a of the head 21, whereby the contents can be discharged with a relatively small pressing force.

[0020] The base 24 is connected to the lower end of the body portion 23 and has a peripheral wall 24a and a top wall 24b. The peripheral wall 24a has an internal thread 24c on its inner wall surface, and the internal thread 24c is detachably attached by being screwed onto and undercut-fitted with an external thread 11a provided on the outer peripheral wall of the neck portion of the container body 1. Further, the central portion of the top wall 24b has an opening 25 connected to the body portion 23, and a cylindrical portion 26 suspended from the edge of the opening 25 is detachably fitted along the inner peripheral wall of the neck portion 11.

[0021] The cover cap 3 has a peripheral wall 31 and a top wall 32. At the connecting position of the peripheral wall 31 and the top wall 32, there is an inner wall surface portion 33 formed by an inclined surface. By the inner wall surface portion 33 being in close contact with the obliquely upwardly directed discharge port 22a of the nozzle 22, the discharge port 22a is sealed and sealed. Further, the rear end 21a of the head 21 (symmetric position with respect to the container axis L of the nozzle 22) has an inclined surface such that the edge contacts the inner wall surface portion 33.

[0022] In the embodiment shown in FIG. 1, on the inner peripheral surface of the peripheral wall 31 of the cover cap 3, a double-threaded screw 34a is provided as an annular convex portion 34. When the cover cap 3 is placed on the pouring stopper 2 and rotated clockwise, the tip of the nozzle 22 and the rear end 21a of the head 21 serve as threads, and by screwing the double-threaded screw 34a with the nozzle 22 and the rear end 21a, the cover cap 3 can be securely attached to the pouring stopper 2. On the other hand, the cover cap 3 can be easily removed by rotating it counterclockwise to release the screwing of the double-threaded screw 34a with the nozzle 22 and the rear end 21a.

[0023] Note that the annular convex portion 34 can be a single-threaded screw 34b as shown in FIG. 3, in addition to a multi-threaded screw such as the double-threaded screw 34a. Further, as shown in FIG. 4, the tip of the nozzle 22 and the rear end 21a of the head 21 may be undercut and fitted to the annular convex portion 34.

[0024] From the above, according to the present invention, not only can the cover cap 3 be securely attached to the pouring stopper 2 via the annular convex portion 34, but also the annular convex portion 34 contacts the lower surfaces of the tip of the nozzle 22 and the rear end 21a of the head 21 and supports them, so that it is possible to prevent the pouring stopper 2 from wobbling, maintain the close contact posture of the discharge port 22a with respect to the inner wall surface portion 33 and the contact posture at the rear end 21a of the head 21, and stably maintain the sealed state of the discharge port 22a by the cover cap 3. Since the cover cap 3 is also held by both the nozzle 22 and the rear end 21a of the head 21, it is possible to prevent the cover cap 3 from wobbling.
