Description

[Detailed description of the invention] Technical field This invention is a low pouring spout type liquid container.
The present invention relates to a low spout type liquid container that includes a liquid content pouring means for pumping the liquid content out of the container body, and a retractable liquid injection guide tube that guides the poured liquid content from the upper part of the container body to the lower part outside the container body.

Prior art The liquid injection guide tube is equipped with a fixed cover to protect it and improve its appearance, and is also designed so that it can swing back and forth with respect to the container body to make it easier to pour liquid into any shape of container. (Utility Model Application Publication No. 135339/1983).

However, the fixed cover becomes large enough to cover the entire swing range of the liquid injection guide tube, making the device large and bulky even when not in use.
In addition, if you operate the operation part installed in the middle of the injection guide tube to change the height or protrusion position of the spout, it is difficult to feel the change in the position of the spout from the operation part, so it is necessary to directly operate the spout part. Although this is desirable, in order to make it easier to operate, the amount of protrusion of the spout from the cover must be increased, as shown in Figure 17 of Japanese Utility Model Publication No. 57-81745, for example.
The effectiveness of the cover is reduced accordingly, and since the pouring spout part is directly touched, it is dangerous to pour out hot water, etc., and that part cannot be protected by the cover.

Purpose The purpose of this invention is to provide a low spout type liquid container that can solve the above-mentioned conventional problems by employing a swinging cover that can swing together with the liquid injection guide tube.

Structure In order to achieve the above-mentioned object, this device includes a liquid content dispensing means for dispensing the internal solution with a pump, and a liquid injection guide tube for guiding the dispensing content liquid from the upper part of the vessel body to the outside and lower part of the vessel body. In the low spout type liquid container equipped with the above, the liquid injection guide tube consists of a base tube forming the upper half and a swinging tube forming the lower half, and the base tube is covered with a fixed cover attached to the outer surface of the container. The present invention is also characterized in that the swing tube is held within a swing cover whose upper end is pivotally supported by the fixed cover so as to be able to swing forward.

Function The lower half of the liquid injection guide tube, which is the swinging tube, extends forward together with the swinging cover that covers it, allowing the spout to be pulled away from the container body to the desired position, allowing it to be attached to any shape of container. Moreover, since the cover can be returned to the stored position along the container body together with the swinging cover, the cover does not make the container bulky when not in use due to the overhang of the liquid injection guide tube. be able to. The swinging tube, which is the lower half of the liquid injection guide tube, can be operated and extended at the spout portion safely through the swinging cover. Furthermore, the upper half of the liquid injection guide tube, the base tube, is covered by a fixed cover, and the lower half, the swinging tube, is covered by a swinging cover, so that the entire liquid injection guide tube is protected. It is limited to the lower half of the guide tube, which covers the swinging tube, and the length is short and the pivoting condition is stable, so it can sufficiently protect the swinging tube of the injection guide tube. can.

A telescopic liquid injection guide 28 is provided below from the part to receive the liquid flowing out from the outlet 27 and guide it to the outside lower part of the container body 1. Liquid injection guide 28
The upper end tube 28a is inserted into the opening 26 from above and the upper end is detachably attached to the opening 26 by helicoid engagement, etc., and the lower end side is fitted to the outer periphery of the upper end tube 28a so as to be vertically movable. The height of the lower end spout 29 is changed by expanding and contracting when the lower end pipe 28b moves up and down.

The lower end side tube 28b has an outer cover 3 covering its outer periphery.
0 is set. The outer cover 30 includes a beak-shaped portion 4a
It is formed in a cross-sectional outer surface shape that is almost similar to the cross-sectional inner surface shape of the passage cover 31 located below and provided on the front side of the vessel body 1, and is guided to move up and down within the passage cover 31 while receiving frictional resistance to the extent that it does not fall by itself. This improves the stability of vertical movement of the lower end side tube 28b and maintenance of the adjusted height. A joint part formed by a hollow spherical fitting part 32 is provided at a position near the upper part of the lower end side tube 28b, and the part below it forms a bendable and extensible lower end part 28c.

The outer cover 30 is provided with a joint portion formed by the left and right uneven fitting portions 33 on a horizontal axis x passing through the bending/extending center point o of the lower end portion 28c, and the lower end portion 28c bends/extends in the front-rear direction with respect to the vessel body 1 around the axis. The pouring spout 29 is placed between a position close to the front surface of the container 1 (solid line and one-dot chain line in FIG. 1) and a position a predetermined distance from the front surface of the container 1 (phantom line in FIG. 1 and FIG. 2). On the other hand, until the concave-convex fitting part 33 comes out below the passage cover 31, the lower half part 30a is prevented from rotating back and forth about the concave-convex fitting part 33, and the lower end of the liquid injection guide This prevents the portion 28c from bending forward to separate the spout 29 from the front surface of the container 1, and the concave-convex fitting portion 33
If it appears under the passage cover 31 as shown by the dashed line in FIG. 1 and in FIG. 2, it can be bent.

In the case of this embodiment, the lower end portion 28c is made to be able to bend forward at the lowest moving position of the lower end side tube 28b, but the point is that it only needs to be able to bend at the use position, and it should always be bent below the desired downward moving position. Just make it possible.

As the lower end portion 28c bends forward and the spout 29 is pulled away from the front surface of the container body 1, the ejected liquid can be easily received into the receiver, so the spring 34
The lower end portion 28c is always urged in the forward bending direction, and as soon as the lower end portion 28c reaches a predetermined downward movement position, it is automatically bent forward and becomes ready for use. When moving the lower end portion 28c upward, even if the lower end portion 28c is moved in a bent state, the lower half portion 30a of the outer cover gradually fits into the passage cover 31 and is automatically extended. There is no need to go through the trouble of stretching it and then moving it up.

The passage cover 31 is integrally molded so as to protrude forward from the synthetic resin panel plate 35 attached to the exterior case 2 and the lower surface of the shoulder member beak 4a, and covers the passage of the panel plate 35. A rear wall 36 is attached behind the cover 31 forming part. Rails 36a are integrally formed on the front left and right sides of the rear wall 36 to guide the vertical movement of the lower end side tube 28b, and are fitted with both edges of the rear wall 30c of the upper half portion 30b of the outer sheath 30. The lower end side pipe 28b is guided through the lower end side pipe 28b.

The upper half 30b of the outer cover and the rear wall 30c have a partially open hole 37 in the top plate of the upper half of the outer cover 30b connected to an outer circumferential groove 38 formed in the upper base 28d of the lower end tube 28b.

A shallow relief groove 45 for the rear wall 30c of the upper half part 30b of the outer cover is carved below the passage cover 31 forming part on the front surface of the panel plate 35, continuously between the rails 36a, and the lower end side pipe 28b is in use. By pulling the passage cover 31 down to the lowest position or lower to disengage the outer cover 30 and the passage cover 31, the outer cover 30 and the passage cover 31 can be removed together. A small protrusion 46 is integrally formed on the upper surface of the bottom of the groove 45 to engage with the rear wall 30c when the lower end side tube 28bb reaches the lowest moving position and prevent the removal. This is done in such a way that it is overcome elastically.

In the embodiment shown in FIG. 4, the joint portion of the lower end side tube 28b is connected to a flexible tube 5 such as a rubber tube provided in the middle thereof.
1. If the spout 29 formed by the lower end side tube 28b is slightly bent backwards as shown by the imaginary line, the orientation of the spout 29 when the lower end portion 28c is bent forward can be changed from directly below. A state close to this can be achieved, and changes in the pouring direction due to changes in the flow rate of the pouring liquid can be eliminated or almost eliminated.

In the embodiment shown in FIG. 5, a bellows part 61 is formed in the middle of the lower end side pipe 28b to serve as a flexible pipe joint. You can connect things.

The embodiment shown in FIG.
The structure is simplified by using a flexible extensible tube whose most part except the upper and lower ends consists of a bellows part 62. The liquid injection guide 28 can be bent and stretched almost entirely, but due to the combination structure with the outer cover 30, the lower end 2
8c is bent and stretched. There is no spring biasing the lower end 28c in the forward bending direction, and the lower end 28c can be stabilized at a desired bending angle by friction between the lower half 30a and the upper half 30b of the outer cover 30. I have to. The upper half 30b and the rear wall 30c of the outer cover 30 are integrally formed.
