Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a container cap structure, and more particularly, to a container cap structure for highly viscous liquids.

[0002]

2. Description of the Related Art A cap structure for a container for detergents or the like, whether for kitchen or furniture, is an A-type cap in which a cap having a spout is opened and closed by a lid continuously provided through an integral hinge. There are a B type in which the outlet has an upwardly expandable valve structure, and a C type in which a lid slides back and forth or left and right on a cap having a spout to open and close the spout.

[0003]

By the way, highly viscous liquids such as liquid cleansers have a higher air-curing property than ordinary synthetic detergents for kitchens and furniture, and are hardened by dripping and are hardened by caps and lids. It has the property of sticking to the body. Therefore, in the A type, the high-viscosity liquid that sticks to the lid or the cap and hardens is caught between the cap and the cap, hindering the lid of the lid, and drying the high-viscosity liquid that is the content. In addition, if the liquid is poured without paying attention to the direction, the highly viscous liquid, which is the content, is poured into the lid and is consumed wastefully, which is uneconomical. Further, in the case of the B type, the high-viscosity liquid inhibits the movement of the vertical expansion / contraction type valve itself due to biting, and in the case of the C type, the high-viscosity liquid which is hardened is caught in the slide guide groove and the lid is closed. This poses a problem because it hinders forward and backward or left and right slides, hinders complete closure of the spout similarly to the A type, and may dry the highly viscous liquid inside. Therefore, a technique has been proposed in which a spout opening on the top surface of the cap is closed with an arc-shaped rotating body whose both ends are rotatably provided on the cap (hereinafter referred to as a D type). The D-type does not accidentally pour the contents into the lid, etc., but cannot be securely closed unless the spout is opened almost flush with the top surface of the cap. Not only does it drool drastically over a wide area up to the container body, but it also becomes uneconomical.

[0004] The present invention has been made in view of the circumstances in the past, and a technical problem thereof is to reliably close a discharge pipe of a cap provided with a discharge pipe for suppressing liquid dripping by a rotating means. An object of the present invention is to provide a cap structure for a container for a highly viscous liquid.

[0005]

According to a first aspect of the present invention, there is provided a cap structure for a container for storing a high-viscosity liquid, wherein an arc-shaped rotating member is provided. The both ends are pivotally attached to the cap, and are rotatably mounted. The stopper, which is fitted to the spout cylinder for suppressing liquid dripping protruding from the cap, is attached to the rotating member, and the stopper is operated in a back-to-back manner. A knob is provided, and a folding part to the cap side is provided at a symmetrical portion on both sides sandwiching the stopper lid, and the pushing part of the operation knob from directly above the dispensing cylinder starts the folding part between the folding parts. The gist of the present invention is that the stopper is folded to the cap side to allow the stopper to be fitted to the discharge tube. The gist of the present invention is that the folding part, the stopper, and the operation knob are integrally formed on the rotating member. And
A third aspect of the present invention is that the folded portion according to the first or second aspect is a thin portion.

According to the above technical means, the following effects are obtained. (Claim 1) The cap structure for a high-viscosity liquid is such that an arc-shaped turning member is turned around a pivot point (turning point) so that an operation knob is turned out to prevent the cap from dripping. The operation knob is pushed downward in a state where it is positioned directly above. Then, the top of the rotating member from above the cap (with a stopper and an operation knob)
Is folded toward the cap with the folded portions on both sides as starting points, the stopper is fitted into the spout, and the stopper is hermetically closed.
In detail, although a pouring cylinder for suppressing dripping protrudes, complete dripping cannot be prevented. Therefore, even if the high-viscosity liquid sticks to the cap or the rotating member, the rotating member is in sliding contact with the pivot point (rotating point), so that there is no biting and the rotation is not hindered. Then, by a downward push from the space directly above the pouring cylinder, the turning member is folded over the cap, and a stopper lid projecting downward closes the spout,
When the cap is closed, it is not affected at all by the highly viscous liquid sticking to the peripheral surface of the cap. (Claim 2) The cap structure for a high-viscosity liquid constitutes a cap structure that achieves the function of the above-described claim 1 by two members, a cap having the pouring cylinder and a rotating member. (Claim 3) In the cap structure for a high-viscosity liquid, the folding portion is constituted by a thin portion formed partially on a rotating member. Although a restoring force for restoring the top portion to the original position is generated in the thin portion, the restoring force with a small force can be suppressed by selecting the thickness of the thin portion and its position. Therefore, the fitted state is maintained, and the plugged state is maintained. Further, depending on the folding depth, it is possible to warp so as not to generate a restoring force. In this case, the restoring force does not become a reaction force of the fitting force.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a cap structure for the present high-viscosity liquid. Reference numeral A denotes a container, and B denotes an arcuate rotating member.

The container A has a general structure in which a screw neck a1 is provided at the upper end and a cap 1 is screwed on the screw neck a1. In this container A, the cap 1
In the present embodiment, has a substantially spherical appearance, the upper end portion is a gently inclined curved surface portion 11, and a pouring cylinder 21 having a desired height for liquid dripping suppression protrudingly formed at the center portion thereof. I have.

The arcuate rotating member B is a band plate B 'made of polypropylene or the like, and both ends of the band plate are pivotally connected to convex portions 31 protruding from symmetrical portions of the lower end portion of the cap 1. The cap 1 is disposed so as to be rotatable so that the inner surface of the cap 1 comes into contact with a desired range of a lower peripheral surface of the upper end portion (around the curved surface portion 11 having a gentle slope) and rubs. The turning member B is integrally formed with a stopper lid b1 fitted to an opening (a later-described outlet) 21a of the pouring cylinder 21 and an operation knob b2 to be back-to-back with the top thereof. The total length of the strip B ′ is set so that the stopper b1 is positioned immediately above the pouring cylinder 21 when the cover b1 is rotated above the top surface of the cap 1.

The stopper lid b1 has a substantially cylindrical shape with a rib having a maximum diameter slightly larger than the diameter of the spout 21a at the end, as in the prior art, and is tightly fitted to the spout 21a. I have.

The operation knob b2 may be of any shape, but in consideration of the design consistency with the cap 1 and the ease of knob operation, in this embodiment, the connecting barrel b2 'as shown in the figure is used. It has a shape in which spherical bodies are continuously connected via the.

Folding portions C are provided on both sides of the arc-shaped rotating member B, which are symmetrically spaced from the stopper lid b1 by a desired distance.
Is formed.

When the operation knob b2 is pinched and the rotating member B is pushed from above, the folding portion C is
The top between C (having the stopper lid b1 and the operation knob b2) is the starting point of the folding into the cap 1 side, and in the present embodiment, is constituted by a thin portion. When the operation knob b2 is pinched and pushed from above by the function of the thin portion, the top portion between the folded portions C, C (having the stopper lid b1 and the operation knob b2) is automatically folded toward the cap 1 side, and the stopper lid b1 is moved. It does not hinder tight fitting to the spout 21a. In addition, although the restoring force for returning to the original state is exerted by the thin portion, the thickness is reduced to a small restoring force so as not to release the tight fit.

The cap structure for a high-viscosity liquid having such a structure is usually provided with the top part folded into the cap 1 side with the folded part (thin part) C, as shown in FIG. The lid b1 is tightly fitted to hermetically close the pouring opening 21a of the pouring cylinder 21 for suppressing dripping. At this time, as described above, the restoring force of the thin portion is small, and the tightly fitted state is maintained. Then, when used, the operation knob b2 is pinched and the stopper lid b1 is artificially extracted from the spout 21a, and rotated by an arbitrary angle from the left or right (see FIGS. 1 and 2). Thereby, the contents can be poured out in any direction of 360 degrees. The contents attached to the cap 1 can be wiped by rotating the rotating member B largely right and left by using the rotating ability.

As shown in FIG. 4, the upper end of the front cap 1 may be constituted by a recess 41 and a pouring cylinder 21 protruding from the bottom of the recess 41 for suppressing liquid dripping. is there. With this configuration, the whole of the arc-shaped rotating member B can be brought close to the cap 1, so that a sense of unity is brought about and the design can be improved.

[0016]

As described above, the present invention has the following advantages. (Claims 1 and 3) The spout of a cap provided with a spout cylinder for suppressing liquid dripping is closed with an arcuate rotating member. The opening and closing method of the spout with this arc-shaped rotating member avoids the inconvenience of accidentally pouring into the lid, such as a cap structure that opens and closes with a lid connected by a hinge, and also allows the cap to be opened from above the cap. Since the stopper that projects downward from the top folded into the side fits into the spout, the stopper can be securely closed without being obstructed by the high-viscosity liquid that inevitably sticks to the peripheral surface of the cap. Is also easy. Accordingly, it is possible to newly provide a cap structure of a container for a high-viscosity liquid, which has both good usability and reliability that does not dry the high-viscosity liquid as a content. In addition, since the pivoting member to be pivotally contacted with the cap is inevitably brought into contact with the cap, it can be effectively used as an element for wiping the contents adhered to the cap by largely pivoting the pivoting member left and right. . (Claim 2) In addition, the effect of the above-mentioned claim 1 is achieved by devising the shape of the one-piece rotating member, and the assembling of the rotating member is simple engagement between the convex portion and the concave portion or between the convex portion and the hole portion. Due to the structure, it can be provided at very low cost.
