[Prior art]
As a jet cap, a synthetic resin made of a cap body having a crest-like shape and a lid that can be opened and closed on the main body is known as a very general form. These are configured to be attached to a mouth portion of a container body or the like and to eject liquid from a spout provided at the top of the cap body.
[0003]
Since these conventional spout caps are easy to open the lid, unauthorized opening of the lid and mischief by infants often occur, resulting in contamination around the spout, illegal spillage of the contents, quality of the content liquid, etc. There was a problem that deterioration and the like occurred.
[0004]
Therefore, an excellent ejection cap has been proposed to solve such problems. This cap prevents the lid from being opened unless a certain operation is performed on the cap body, prevents unauthorized opening, and provides a reliable sealing property.
[0005]
The spout cap has an assembled portion that has a top tube shape that is closely assembled to the mouth portion of the container, and a short cylindrical pipe tube piece is extended from the extended end of the outer casing extending from the peripheral edge of the top plate. A skirt cylinder is suspended from the lower end of the hanging cylinder piece via an outer flange-shaped outer flange, and a cutout is provided on the side of the combination of the outer casing, the hanging cylinder piece, the outer flange, and the skirt cylinder. A cap body in which an elastic piece remains in an upright shape and a locking piece projects from the upper end of the bullet piece, and a hinged cylinder is hinged to the rear end portion of the cap body so as to be opened and closed by a hinge portion. It is made of a synthetic resin composed of a lid provided with a locking hole into which the locking piece is fitted from the inside on a side portion of the peripheral wall that is fitted on the piece.
[0006]
The ejection cap pushes in the bullet piece and removes the locking piece from the locking hole, and then opens the lid with a different operation form. Never become. As a result, it is possible to reliably prevent the occurrence of inconveniences such as illegally flowing out of the content liquid and contaminating the surroundings, deterioration of the content liquid due to evaporation, and pride adhering around the jet outlet, etc. It can exhibit a special effect.
[0007]
[Problems to be solved by the invention]
However, in the case of use in a state where it is not necessary to consider unauthorized use or misuse, it is troublesome to open the lid with another hand after pressing the bullet piece, and there are people who have difficulty with one hand. It is also inconvenient when used.
[0008]
The present invention has been made in view of the above points, and proposes an ejection cap that can exhibit the effects of the above-described conventional ejection cap and can be easily opened with one hand by a simple operation. is there.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
The jet cap 1 of the present invention is made of synthetic resin and includes a cap body 2 and a lid 3.
[0012]
The cap body 2 is formed in a cylindrical shape with a top and a lower end provided with a spout 4 at the top, and is used by fitting into a mouth of a container body or the like. In the illustrated example, the top wall 6 is extended from the upper end edge of the peripheral wall 5 in the shape of a horizontally long elliptical cylinder, and the jet port 4 is opened at the front of the top wall 6. The spout 4 is open on the front surface of the dome-shaped protrusion. Further, the upper end portion of the peripheral wall 5 is formed in a reduced diameter portion 5a that is reduced in diameter via an inward flange 7, and the peripheral wall of the lid 3 is configured to fit on the outer periphery of the reduced diameter portion 5a. Further, a short seal cylinder 8 communicating with the jet nozzle 4 is provided at the center of the back surface of the top wall 6 and a long fitting cylinder 9 is provided vertically at a predetermined position outside the seal cylinder 8. The mouth portion is configured to fit liquid-tightly.
[0013]
The lid 3 is provided on the cap body 2 so as to be openable and closable, and a lid whose lower end is connected to the rear upper end of the cap body 2 so as to be rotatable by a thin hinge or the like is adopted. In addition, the lid 3 is urged in the opening direction when it is opened to a predetermined angle in addition to the one that is pivotally connected by a thin-walled hinge or the like, and then automatically opens. Thereafter, the lid 3 is opened at a predetermined angle from the opened state. It is also possible to use a connecting means having a so-called elastic reversing mechanism that is urged in the closing direction when it is closed to close automatically thereafter.
[0014]
In the illustrated example, the lid body 3 is integrally formed with the cap body 2 by a synthetic resin, and the top wall 11 is extended from the upper edge of the peripheral wall 10 in which the lower end is fitted to the outer periphery of the reduced diameter portion 5a of the cap body 2. A pair of elastic plates 13 are connected to each other by connecting the lower end of the rear portion of the peripheral wall 10 and the upper end of the rear portion of the cap body 2 with thin hinges 12 and connecting the upper and lower ends with thin hinges. These thin hinges and elastic plates constitute a known elastic reversing mechanism. Further, a plug cylinder 14 that is fitted to the dome-shaped protrusion and closes the jet nozzle 4 is integrally provided at a predetermined position on the back surface of the top wall 15.
[0015]
In the present invention, the engaging piece 15 is provided in the cap body 2 for the purpose of preventing unauthorized opening of the lid 3. The engaging piece 15 is formed in a band shape from the peripheral wall 5 of the cap body to the edge of the top wall 6 and engages the upper end so as to prevent the lid from being opened on the inner peripheral wall of the closed lid and the inside thereof. In addition, it is possible to push inward to release the engagement.
[0016]
In the illustrated example, a belt-like window hole 16 extending from the lower part of the peripheral wall 5 to the edge of the top wall 6 is provided at the front part of the cap body, and the engaging piece 15 is erected in the window hole 16 so as to be able to be pushed. . The engagement piece 15 is formed by integrally connecting the lower end edge to the lower surface of the window hole 16 and has a vertically long plate shape standing along the peripheral wall 5 of the cap body so that the lid 3 can be fitted to the outer surface of the upper end portion. The diameter is reduced inward, an engagement protrusion 17 is provided on the outer surface of the reduced diameter portion, and the engagement protrusion 17 is engaged with an engagement hole 18 formed at a predetermined position in front of the peripheral wall 10 of the lid 3. It is configured as possible. Instead of the engagement hole 18, an engagement recess may be provided.
[0017]
Further, in the present invention, a push-up projection 19 is provided on the outer surface of the lid peripheral wall 10 at the position where the engagement piece 15 is formed, and the finger that has pushed the engagement piece 15 can slide upward. The lid 19 can be opened by pushing up the protrusion 19 for pushing up with a finger.
[0018]
As long as the lid 3 can be pushed up, the projection 19 may project at any position on the outer surface of the lid peripheral wall 10 where the engagement piece 15 is formed. It can be provided at the upper end portion of the outer surface of the body peripheral wall 10, or it can be provided at the lower end portion of the outer surface of the cover peripheral wall 10 as shown in the embodiment of FIG. Further, the shape of the protrusion 19 is not limited to the normal protrusion shape as shown in FIGS. 1 and 6, but as shown in FIG. 7, a plurality of protrusion-shaped protrusions formed on the outer surface of the peripheral wall 10 of the lid. It may be 19b. In this case, the lid 3 is opened by frictional force while pressing the front surface of the protrusion. These can also be used together. For example, a protruding protrusion 19a may be provided above the protruding portions 19b having a plurality of protrusions.
[0019]
The configuration in which the finger that has pushed the engagement piece 15 can slide upward and the lid 19 can be opened by pushing up the projection 19 is when the projection 19 is located at a position other than the lower end of the lid peripheral wall 10 When the engaging piece 15 is fully pushed, the requirements such as the pushing width and the wall thickness are adjusted so that the front surface thereof is substantially in the same position as the front surface of the lid peripheral wall 10. In addition, when the protrusion 19 is at the lower end of the cover body peripheral wall 10, each requirement must be such that when the engagement piece 15 is sufficiently pushed in, the front surface thereof exists at a position where the protrusion 19 can be pushed up. adjust.
[0020]
The case where the above-described ejection cap 1 is used will be described. The ejection cap 1 is mounted in a liquid-tight manner by fitting a mouth 20 such as the container body A between the seal inner cylinder 8 and the fitting cylinder 9. In use, the engagement piece 15 is pushed inward, the engagement protrusion 17 is removed from the engagement hole 18, the finger that has pushed the engagement piece 15 is slid upward, and the protrusion 19 is pushed up to open the lid. The body 3 is opened and liquid is ejected. Accordingly, the lid 3 is not normally opened only by pushing the engagement piece 15, and it is possible to prevent an infant's mischief and inadvertent opening, while the finger can be slid upward as it is. For example, the lid can be opened with one hand, and it can be easily opened even by a person with a disability in one hand. After use, the engagement protrusion 17 and the engagement hole 18 can be fitted and closed. In addition, in the said Example, although the ejection cap 1 is used in the case of the ejection of a liquid, it is also possible to use in the case of the extraction of a liquid, and in that case, it is desirable to change the form of an ejection outlet, etc. .
[0021]
【The invention's effect】
As described above, since the ejection cap of the present invention is configured as described above, it can prevent unauthorized opening due to mischief of an infant or the like, and can prevent inadvertent leakage of liquid. Further, when the user is a person who does not need to worry about unauthorized opening, the lid 3 can be easily opened and closed, and the lid can be opened with one hand.
