Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a liquid container having an elliptical cross-sectional shape, which is mainly used as a portable heat-insulating bottle.

(Prior art) This type of liquid container is not bulky when carried and is stable along the human body even when carried over the shoulder, so it has an oval, oval, or slightly curved spherical shape when viewed from a plane. It is provided and used as a water bottle.

(Problems to be Solved by the Invention) However, the planar shape has not been devised to produce any advantages other than being convenient to carry.

Therefore, the present invention focused on the fact that the above-mentioned shape characteristics cause a tendency for the container to be grasped in the direction of the short axis where the width is narrow when gripping the container with one hand. The purpose is to provide a container.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a container body having an oval cross section with a mouth portion having a circular cross section, and the shoulders of this container body. A cap having an elliptical cross section that is fitted into the member is provided, and the shoulder member has a substantially full length defined by the mouth and the circumferential wall of the cap in the longitudinal direction of the cap from the mouth position of the vessel body. The device is characterized by being provided with a liquid injection port that extends by holding the device.

(Function) According to the above structure of the present invention, the vessel body has an elliptical cross section and is naturally grasped in the direction of its short axis.
The user can then move on to the operation of tilting the container body in the longitudinal direction, and since the liquid inlet extends in the direction of tilting, the operation of pouring out the liquid content is carried out very naturally and smoothly.

In particular, since the container body having the above-mentioned shape has a mouth portion with a circular cross section at the upper end and a long shoulder portion in the longitudinal direction, the spout provided in the shoulder member of the container body is
The container extends from the mouth position of the container body in the longitudinal direction of itself with a length defined by the mouth portion and the peripheral wall of the cap, so that it protrudes from the side surface of the container body and the cover area of the cap. It can have a length corresponding to the long shoulder of the container body without causing any trouble, and the liquid can be guided for a long time and poured out smoothly.

(Embodiment) To explain the first embodiment of the present invention shown in FIGS. 1 and 2, as shown in FIG. This figure shows a case of a portable bottle made of a vacuum double container made of metal and having a cap 1 and a cap 8. The container body 1 has a vacuum heat-insulating space 1c formed between a metal inner container 1a and a metal outer container 1b using a known method, and has a narrow opening 1d with a circular cross section.
A bottom cover 3 made of synthetic resin is attached to the outer side of the bottom of the container body 1 by force fitting between a protrusion 1e and a groove 3a.

The narrow opening 1d of the container body 1 has a female screw 4a screwed onto the outer thread 1f, and a synthetic resin stopper 4 is detachably attached thereto, and when the stopper 4 is closed, the stopper is inserted into the narrow opening 1d. The tip seal packing 5 of 4b comes into pressure contact with the valve seat portion 1g on the inner periphery of the narrow opening 1d, thereby sealing the container body 1. A heat insulating material 6 is fitted into the plug 4.

The shoulder portion 1h of the vessel body 1 is entirely covered with a shoulder member 7 made of synthetic resin. The shoulder member 7 is attached to the container body 1 by having the inner diameter part fit into the outer circumference of the narrow opening 1d and the grooved strip 7a being force-fitted to the protrusion 1i at the base thereof, and the peripheral wall 7b of the outer diameter part fitting into the outer circumference of the shoulder part 1h. The external appearance of the shoulder portion 1h is adjusted by fitting into the stepped portion 1j, and a pouring plate portion 22 having an opening 21 communicating with the narrow opening 1d at the upper end is integrally formed. A mouth packing 23 is interposed between the opening 21 and the narrow mouth 1d to form a liquid supply/drainage port 24 of the container body 1.

The pouring plate portion 22 has a beak-shaped liquid pouring port 27 integrally formed on one side thereof facing in one of the longitudinal direction, that is, the major diameter direction when viewed from the plane of the container body 1, and has a top plate 25 at the upper end. . The top plate 25 has an opening 2 for attaching and detaching the stopper 4.
6 is formed, and the stopper 4 is inserted through this opening 26.
is inserted into the pouring tray part 22 and screwed onto the inner periphery of the peripheral wall excluding the part where the liquid inlet 27 is formed, and the lower end 4a is pressed against the opening packing 23 to close the liquid supply/drainage port 24.

The stopper 4 is a known so-called one-touch stopper that changes sequentially between an open state and a closed state each time a push button 28 on the top surface is pressed. A valve body 31 having a passage 29 and closing an opening 29a of the passage 29 to the lower end of the stopper 4 by the force of a spring 30 is operated by the push button 28 via a cam mechanism 31.

Further, the shoulder member 7 is formed with a cap receiving portion 7c for mounting a synthetic resin cap 8 that covers the entire shoulder member 7.

The cap receiving portion 7c includes a fitting protrusion _7c1 that fits into the opening of the cap 8, and a stepped portion 7 that receives the cap 8.
c ₂ to stabilize the cap 8 in a predetermined mounting state.

An engaging protrusion 7d that engages with the protrusion 8a on the inner periphery of the opening of the cap 8 is formed on one side in the long diameter direction of the fitting protrusion 7c ₁ of the shoulder member 7, and the engagement with the protrusion 8a causes the cap 8 to close.
One side in the long diameter direction is locked in a closed state.

A cap locking member 10 is provided inside another side of the shoulder member 7 in the long diameter direction opposite to the above-mentioned side, making use of a dead space 9 formed between the shoulder member 7 and the shoulder 1h. The cap locking member 10 has an external operation part 10a that fits into a hole 7e formed in the peripheral wall 7b of the shoulder member 7 and projects to the outside. The operating section is guided so as to be movable forward and backward in the radial direction of the shoulder member 7, and is biased outward by a spring 11 acting between a spring protrusion 7f protruding from the back surface of the shoulder member 7. 10a is stabilized in a state in which it protrudes to the outermost side.

The cap locking member 10 is further provided with a locking hook 10b that projects through the hole 7g on the side surface of the fitting protrusion _7c1 of the shoulder member 7, and the locking hook 10b and the locking hook 10b are formed on the inner periphery of the opening of the cap 8. Engagement protrusion 8b
The other side of the cap 8 in the longer diameter direction is locked in the closed state by engagement with the cap 8.

The cap 8 is now locked in the closed state at two locations on both sides in the major diameter direction and is stabilized.

The engagement between the protrusion 8a and the protrusion 7d on one side is such that when the cap 8 is fitted into the fitting protrusion 7c1 and attached to the container body ₁ , the protrusion 8a side of the cap 8 is connected to the step 7c. ₂ , the protrusion 8a is inserted below the protrusion 7d, and then the other side of the cap 8 is stepped using the engaging portion of the protrusion 8a and 7d on the one side as a fulcrum. By pressing against the portion _7c2 , the protrusion 8b elastically engages with the locking hook 10b under the action of the spring 11 by utilizing the slippage between the protrusion 8b and the upper slope _10b1 of the locking hook 10b, and the protrusion 8b and the locking hook 10b can be automatically engaged.

Therefore, the protrusion 8a allows the cap 8 to be locked in the closed state at two locations without being forced to fit.
7d, this can be done reliably by the engagement between the protrusion 8b and the locking hook 10b.

On the other hand, when the operating portion 10a is pushed in by hand, the cap locking member 10 is moved backward along with the locking hook 10b against the spring 11, and the locking hook 10b
deviate from b. As a result, the locking on one side of the cap 8 is released, and this one side of the cap 8 is lifted using the engagement portion between the protrusions 8a and 7d, which are still engaged on the other side, as a fulcrum. Fitting protrusion 7
When removed from c ₁ , the engagement between the protrusions 8a and 7d can also be removed. In particular, this series of operations is performed on cap 8.
This can be done almost with one touch by placing the little finger of the hand placed on the side surface of the cap 8 on the side where the protrusion 8a is formed and the thumb on the operating portion 10a and moving toward the cap side while pushing.

Connecting portions 13 for the hanging cord 12 are integrally formed at the lower ends of the peripheral wall 7b of the shoulder member 7 on both sides in the longitudinal direction.
The hanging strings 12 are connected by a ring 14.

The cap 8 has vertical ribs 8c formed at the protrusions 8a and 8b with the same degree of protrusion in order to facilitate mold removal when forming the protrusions 8a and 8b.
, one of which opposes the liquid inlet 27, and when the cap 8 engages the protrusion 8b with the locking hook 10b around the engagement portion between the protrusions 8a and 7d, the liquid inlet 27 is opened. It is pressed against the tip 27d to close it, and this closed state is firmly maintained by the projection 8b engaging the locking hook 10b and locking the cap 8 in the closed state.

Therefore, even if the user forgets that the stopper 4 is left open or closes the cap 8 without knowing it and knocks down the container 1, it is possible to prevent a large amount of the liquid from flowing out.

In the second embodiment of the present invention shown in FIG.
1a is located, and a slide port 27a of the liquid injection port 27 is integrally connected to the slider 51, so that when the slider 51 opens the valve body 31, the slide port 27a protrudes. The liquid injection port 27 is extended to facilitate liquid injection, and when the slider 51 closes the valve body 3, the slide port 27a is moved back so as not to interfere with the closing of the cap 8.

In particular, when the slide opening 27a protrudes, it is at a position where it interferes with the closed cap 8, as shown by the imaginary line, and obstructs the attachment of the cap 8, thereby preventing the attachment of the cap 8 with the stopper 4 open. In addition to preventing this, the system also notifies the user that the stopper 4 remains open and prompts the user to close the stopper 4.

The slider 51 has a slope 51b that pushes open the valve body 51.
and an engagement recess 5 that holds the valve body 31 in the push-open position.
1c, both of which act on the valve stem 31a of the valve body 31.

A so-called flap valve 52 is provided at the tip of the slide port 27a.

The third embodiment shown in FIG.
The engaging portions are provided on both sides of the vessel body 1 in the short diameter direction, and other aspects are the same as in the first embodiment.

In the fourth embodiment shown in FIGS. 5 and 6, the body of the operating portion 10a of the cap locking member 10 is also used as a cap locking portion 10c, and the cap locking portion 10c is provided on the cap 8. This embodiment is different from the first embodiment in that one side of the cap 8 is closed by engaging the locking hole 61.

In this case, push the operating part 10a into the locking hole 61.
It is easy to lift and release the cap 8 at the same time as disengaging it from the cap.

The portion of the cap 8 that forms the locking hole 61 is a handle piece 62 to avoid creating a hole in the main body.

The container body 1 has an outer cover 63 made of synthetic resin, and the shoulder member 7 is attached to the narrow opening 1d of the container body 1.
A seal packing 24 is applied to the upper end, and the lower end of the peripheral wall 7d of the shoulder member 7 and the upper end of the peripheral wall of the bottom cover 3 which is applied to the bottom of the container 1 are connected to an outer surface having a force-fitting part 25 therebetween. The container body 1 is connected by a cover 63 and pushed up by an inner screw 66 screwed into the center of the bottom cover 3, thereby pressing the container body 1 against the shoulder member 7 and stabilizing the whole body.

The narrow opening 1d is configured such that the plug 4 is screwed into a female screw 7i formed in the inner diameter hole 7h of the shoulder member 7, so that the narrow opening 1d can be sealed as in the first embodiment.

A shallow, tub-shaped liquid inlet 67 facing in the longitudinal direction of the vessel body 1 is formed on one side of the upper end of the shoulder member 7 where the inner diameter hole 7h opens.

Note that in order to urge each cap locking member 10 outward, a cap locking member 10 as shown in FIG. 7 is used.
A resin spring 71 integrally formed with the cap, or a leaf spring 7 attached to the cap locking member 10 as shown in FIG.
2, or a linear spring instead.

Further, the cap locking member 10 may be configured to engage and disengage from the locking portion 81 of the cap 8 in a rotating manner as shown in FIG. 9, or in a sliding manner as shown in FIG. It may be something that engages with and disengages from the locking portion 81.

(Effects of the invention) According to the invention, the liquid injection port can be provided in a direction that allows liquid to be poured by natural handling in which the vessel body, which has an elliptical cross section, is gripped in the short circuit direction and tilted in the major axis direction. Since the container body having the above-mentioned shape has a mouth portion having a circular cross section at the upper end and a long shoulder portion in the longitudinal direction, the spout provided in the shoulder member of the container body is connected to the mouth portion of the container body. The cap extends from the main body position in the longitudinal direction of the cap to a length defined by the mouth and the circumferential wall of the cap, so that it protrudes from the side of the container body and the covering area of the cap, making it difficult to handle and avoid handling. It has a length corresponding to the long shoulder of the device without getting in the way of installation or making the appearance unsightly, and allows the liquid to be guided for a long time and poured smoothly, making it safe to use. It becomes easier to do.
