Description

Lid for double cup {cap for mug build a double walls}

The present invention relates to a cup having a double wall, and more particularly to a double cup lid having a structure that can open and close the cup outlet.

The double cup is double walled, so the temperature of the contents is not transmitted to the user.

In general, the double cups are made in the form of mugs because of their relatively large volume, and in particular, the cups are mainly used as simple cups used during operation.

Any double cup that has been put to practical use has a lid, and the lid has a structure in which a packing is provided on the outer circumference to maintain airtightness, and a spout is opened on the upper surface.

Such a structure is not inconvenient for the user to use as a cup, but the spout provided on the upper surface of the lid is always open and has a problem of being hygienic.

On the other hand, the lid of the double cup is also known as a structure that can be opened and closed, for example, published in US Pat. No. 6,367,652 B1 shows that the entire lid is opened and closed. In addition, the structure disclosed in the U.S. design publication Des 355,846 also rotates the lever attached to one side of the lid so that the spout can be opened and closed.

However, assuming that a double cup is used in an automobile cup, the structure of opening and closing the entire lid is not preferable because the contents are inadvertently spilled, and it is difficult to guarantee the airtight state through the lid.

In addition, the structure in which the spout is opened and closed by the operation of the lever has a disadvantage in that the structure and assembly hand is complicated because the valve body that is supported by the spring should be installed inside the lid.

Accordingly, the lid of the double cup can be kept airtight when closed, it is easy to operate, it is best to be able to produce and manufacture inexpensively through the simplification of the structure.

Accordingly, an object of the present invention is to provide a lid for a double cup improved in a structure that can be easily assembled, and the user can easily open and close the parts injected by the mold.

According to the above object of the present invention, both sides of the ejection faucet protruding from the guide to the upper surface of the body, it is configured to assemble by fitting the inner guide groove of the stopper to the guide of the ejection faucet.

The stopper opens and closes the spout as the slide moves from the spout. At this time, the guide and the guide groove form a protrusion having a correlation to control the slide stroke of the stopper.

In addition, a long hole may be provided to the guide so that the slide movement of the stopper can be performed smoothly so as to be elastically deformed when the stopper moves.

In addition, the slide control of the stopper may also be carried out by adjusting the outside size of the pouring tap and the inside size of the stopper.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a planar cross-sectional view showing an embodiment related to the structure of the main part of the present invention in a plug disconnected state, the circular plug body (2) is formed integrally projecting the spout 4 on one side, the spout In front of (4), the spout 6 is open.

In the spout 4, both sides protrude outward to form a guide 8 on a rail. On both side guides 8 of the spout 4, the control protrusion 10 is projected outward at at least one predetermined place.

The stopper 12 has a guide groove 14 fitted into the guide 8 with respect to the spout 4, and is also correlated with the control projection 10 inside the guide groove 14. The projection 16 is formed to protrude.

The present invention having such a configuration is completed by the plug 12 is covered on the spout 4. That is, the stopper 12 is combined by fitting the guide groove 14 along the guide 8 of the spout 4, wherein the projection 16 is positioned between the two control projections 10 of the guide 8; You can assemble it.

When assembled, the stopper 12 is able to slide along the trajectory defined by the guide 8 of the ejection faucet, and the slide trajectory is a control protrusion 10 to which the protrusion 16 can move as shown in FIG. 2. It is limited to the interval between), due to the slide movement of the stopper 12 is the spout 6 is to be opened and closed.

Although the above-described embodiment shows an example in which the projections 16 are positioned between the two control protrusions 10 arranged at regular intervals so that the stroke is limited, the present invention is not limited thereto. It may be implemented together.

FIG. 3 shows another embodiment related to the present invention. In this example, the control groove 10 is formed at a predetermined position of the guide 8, while the guide groove 14 of the stopper 12 is formed. It has a structure in which two pairs of protrusions 16 are installed at regular intervals.

In this structure, the opening and closing positions of the stopper 12 may be classified accordingly as the control protrusion 10 is positioned between the pair of protrusions 16.

However, even in the case of this embodiment including the above embodiment, when the control protrusion 10 and the protrusion 16 are excessively mutually, the user feels a considerable reaction force and the operation feeling is not good.

Figure 4 shows another embodiment of the present invention with a structure that feels a smooth operation feeling.

In the drawing, the guides 8 on both sides of the spout 4 have a long hole 18, and the long hole 18 is provided only in a portion where the control protrusion 10 is formed.

The long hole 18 may be particularly suitably used in the embodiment depicted in FIG. 3 because the control protrusion 10 is formed to have an elastic force, which is controlled when the stopper 12 is opened or closed. Is deformed by being pushed inward when it encounters the protrusion 16 and then restored to its own elastic force so as to be positioned between the pair of protrusions 16, thereby preventing resistance to the opening and closing operation of the stopper 12. FIG.

Although the above-described embodiment allows the opening and closing stroke of the plug to operate depending on the correlated projection and the control projection, it is not necessarily limited to the illustrated structure, and as shown in FIG. 5, the friction force by adjusting the specification of the spout and the stopper is shown. A change action can also be added.

FIG. 5 is a plan view of the main part showing another embodiment of the present invention, in which the projection tip width W1 of the spout 4 is set to a size larger than the stem width W2 following the body 2, and vice versa. (12) shows an example in which the rear end width L1 is set to a size smaller than the front end width L2.

In the illustrated structure, the standard difference between the tip width W1 and the stem width W2 and the standard difference between the rear end width L1 and the front end width L2 are preferably about 0.1 mm, and the rear end width ( L1) should be set larger by the allowable tolerance compared with the protrusion tip width W1.

Accordingly, the stopper 12 is easily moved due to a small frictional force when moving to the open position when the stopper 12 is slid from the upper surface of the spout 4, but when moving to the closed position, the frictional force increases toward the end and the plug 12 is closed. Can be kept stable.

This embodiment may be implemented alone, but it is more preferable to apply as an additional means to the above-described embodiment.

As described above, the present invention has the advantage that all the necessary parts can be injection molded and have a structure that is assembled to fit together, and thus, there is an advantage of simplifying production assembly. It is easy to use because it can be opened and closed by easy operation.
