Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closure cap that seals a container tIf15 minutes.

It is now quite common for consumer products such as liquid detergents to be sold in bulky containers. For example, synthetic fabric softening detergents are sold in plastic containers of 4 liter capacity, and liquid dishwashing detergents are sold in containers of up to 10 liters. Often these containers are stylized and it is therefore desirable for aesthetic reasons to provide them with a modestly sized closure cap. Furthermore, some products are constructed to act as caps and are therefore sold in containers of large capacity, perhaps 60-120 milliliters #1, etc.

Currently, when specifying large capacity caps, the conventional practice in the art is to configure the container cap to extend upwardly into the inside of the hem of the cap, with the top often tapered to fit within the container cap. It is designed to be sealed by fixing it to.

The above arrangement is illustrated in FIG. 1 of the accompanying drawings. The neck 10 of the screw bottle extends upwardly inside the hem 11 of the cap. The upper part of the skirt is provided with threads 13 for engaging the threads 14 of the container's cap, and the top part 15 of the cap is provided with a projecting tapered volume 16 for fitting and sealing inside the container's die. It has become.

A disadvantage of the construction shown in FIG. 1 is that when the cap is used as a container for liquids, residue hangs on the sides of the bottle, making it uncomfortable to handle by hand.

According to the present invention, there is provided a closure cap for a container which also serves as a measuring cup, comprising a top part, a skirt part, and a retaining part which cooperates with a corresponding retaining part of the container to retain the cap on the neck of the container. and a closure means for engaging in a sealing relationship with the cap of the container, the cap comprising a cap such that both the retaining portion and the closure means are formed on a bottom portion remote from the top portion.

Embodiments of the closure cap of the present invention are shown in Figures 2 to 7.

In each figure, the container forms a shorter neck 10 than that shown in FIG. The hem 11 of the cap is provided with a retaining member in the form of a thread 13 which cooperates with a corresponding thread 14 on the cap of the bottle.

Referring now particularly to FIG. 2, the hem of the cap is stepped and the retaining portion is threaded 13 carried on the larger diameter portion.
Consisting of In this embodiment, the sealing means comprises a tapered downwardly projecting sealing ring 16 formed as an extension of the smaller diameter portion of the skirt.

The edge of the bottle thus engages the Ull groove formed by the top of the threaded portion of the skirt 18 and the sealing ring 16, which further facilitates sealing.

A similar structure is shown in FIG. 3, but the difference is that the hem of the cap is shaped like a shear, rather than stepped. As the skirt wall extends, a sealing ring 16 projects therefrom at an acute angle and abuts the top surface of the bottle cap to form a seal.

In FIG. 4, the sealing means consists of a separate sealing Zorag 17 of reinforced cork or deformable plastic material, which is loosely fitted into the closure cap and press-fitted into the bottle cap. In this case, after removing the cap, it is necessary to separate it from the inspector and remove it.

Referring now to FIG. 5, the sealing means in this embodiment is also a separate insert, but in this case a dished plastic insert 18, the outside of the dished wall being on the inside of the neck of the bottle. It abuts an inclined surface 19 and the edge of the wall abuts at 20 a second inclined surface on the inside of the hem, thereby forming a seal.

FIG. 6 shows an embodiment similar to that shown in FIG. 3, except that the outwardly projecting closing ring 16 abuts a conical surface 21 formed on the outside of the neck of the bottle. ing.

Finally, with reference to FIG. 7, an embodiment is shown in which the sealing means consists of a sealing ring 16 formed on the edge of the hem abutting a shoulder 22 formed on the violet of the bottle.

The structure shown in FIGS. 2 through 7 can have two advantages. First, all constructions save on the amount of material needed to construct the container, since there is no need to provide a long neck extending upwardly inside the hem of the cap. Second, when the cap is used as a measuring cup to measure the liquid contents of the container, the closed position reduces the possibility of liquid dripping out of the container.

Claims (1)

[Scope of Claims] (1) A closure cap for a container that also serves as a measuring cup, wherein the top, skirt, and corresponding retaining portion of the container cooperate to hold the cap in the opening of the container. In a cap having a retaining portion and a sealing means that engages in a sealing relationship with the violet portion of the container, both the retaining portion (13) and the sealing means (16) are formed in the large hem portion (11) away from the top portion. cap that has been (2. A closure cap that also serves as a measuring cup as described in Claim S 1 In the closing cap that also serves as a measuring cup as described in Scope 1 A closure cap which also serves as a measuring cup, in which the sealing means (16) includes an outwardly protruding sealing ring configured to abut against the bottom of the bottle. (5) A cap which also serves as a measuring cup according to claim 4 A closure cap configured such that the closure ring abuts the inside of the violet of the bottle.
