The technical field to which the invention relates.
The present invention relates to a container with improved susceptible to capture by the surface and, in particular, to a container, comprising a housing and a cap of the container, with each of these elements has one or more improved amenable to capture surfaces.
Background of invention
Many containers, such as banks, have a top opening and a lid or other closure means, intended to close or cover the holes. One typical design includes a hole made with a thread of the bottle opening, which cover with the corresponding thread is twisted and twisted off. To ensure measurable gripping surface some covers include ribs or grooves along their part, passing in the longitudinal direction, commonly known as the lower hollow cylindrical portion, for providing enhanced grip and, therefore, to provide a lighter twist user cap on the neck of the container and removing it from the neck of the container.
In U.S. patent No. 6481589 disclosed capping agent for the banks, in which the hard part forms the first part of the cover, including the lower hollow cylindrical part and a second part formed on the first, estcoy parts for the education of the periphery of the outer surface of the cover. The second part formed within the cavity or cavities of the lower hollow cylindrical part, so that the resulting cover has a second part made flush with the outer surface of the bottom of the hollow cylindrical part and/or with the top of the first part of the cover.
The publication of the patent application U.S. No. 2005/0145593 disclosed cover captured with a soft surface, in which pre-formed label forms a thin capture surface on the bottom of the hollow cylindrical part of the cap.
Access to the contents of the known container with thread get through the application of torque to the lid with the simultaneous application of pressure to the sides of the casing of the container, thereby holding the housing stationary while unscrewing of the cap from the housing. Thus, torque applied to the cap, must be counteracted by an appropriate torque is applied to the body. For the application of sufficient torque to the body to counter the torque applied to the cap, the user typically must shrink the body of the container is very strong, or to hold the body of the container to a work surface or table top, or to use any other ways. All these methods are sticky and uncomfortable and compression of the body of the container may cause indentation of the container inside and squeezing some content from the container during opening.
In the art there is a need for an improved container having a measurable gripping surface that allows easy opening and closing of the container.

A detailed description of the preferred embodiments
In the drawings, similar elements are denoted by the same numbers in some species.
The container 14 includes a housing 19 and the cover 10. The cover 10 has an upper part 11 and lower hollow cylindrical portion 12. Preferably, the cover 10 is formed from a plastic or polymer by injection molding on the first stage. The cover 10 may be composed of polyethylene or polypropylene. Alternatively, the cover 10 may be formed from any other suitable material well known to the average person skilled in the technical field.
The cover 10 includes an outer layer 13 attached to the bottom of the hollow cylindrical part 12 and preferably covering essentially the entire surface of the part 12. The outer layer 13 is connected with the part 12 so that the outer layer 13 does not slip and does not move relative to the part 12 by tightening or loosening the cap 10 for opening or closing the container 14 (figure 4).
In one paragraph edocfile the method of manufacturing the cover 10 of the outer layer 13 is formed during the second stage of injection molding. Preferably the resulting outer layer 13 is attached to the portion 12 through the formation of intermolecular bonds in such a way that the boundary surface (boundary layer) 16 is formed between them, will include material from part 12 and the outer layer 13, mixed with each other, as shown in figure 3. Although it is preferable to have cohesion between the part 12 and the outer layer 13 is not necessary to have cohesion to ensure the absence of bias the lower part 12 and the outer layer 13 relative to each other.
The thickness of the outer layer 13 is at least 20 mils, preferably at least 38 mils and more preferably 40-60 mils. These thicknesses provide education be comfortable gripping surface along part 12 of the cover 10 to provide easy gripping and opening of the container 14 by the user. The outer layer 13 can be formed of any suitable soft material, which includes a rubberized elastomer.
Although the preferred method of forming closures 10 is a two-step injection molding, alternatively, can be used in any other way manufacturing, well known to the average expert in the field of technology, which provide the t formation the lower hollow cylindrical portion 12 with a sufficiently firmly attached or glued softer outer layer.
The outer surface of the housing 19 of the container includes measurable capture surface 20 surrounding the housing 19 around its middle part, and/or amenable to capture surface 22 formed at the base body 19 of the container. The surface 22 is held to the bottom 24 of the housing container (5). Be gripping surface 20, 22 have a high coefficient of friction relative to the rest of the outer surface of the shell 19. In the result, the user can firmly hold the housing 19 by holding one of the measurable gripping surfaces when removing or unscrewing of the cap 10. Alternatively, you can apply pressure and push the surface 22A of the housing 19 of the container down to the tabletop or other surface until the user removes or twists/attracive the cover 10. Although figure 5 shows amenable to capture surface 22A as covering only the peripheral part of the bottom 24 of the housing 19, amenable to capture surface 22A can cover all of the bottom 24.
Be gripping surface 20, 22 can be formed from a softer material than the material of the rest of the body 19, and may be attached to the surface through the formation of intermolecular bonds. For example, measurable gripping surface 20, 22 can be formed by using dogsleding the injection molding, similar to the process that can be used for formation of the outer layer 13 on the cover 10. Alternatively, the curable gripping surface 20, 22 can be composed of rubberized material, which is deposited on the surface of the housing 19. Be gripping surface can also be formed by a textured outer surface of the shell 19. Textured surface can be formed during molding of the housing 19 or the housing 19 of the container may be attached to the surface roughness after the process of injection molding. Preferably measurable gripping surface 20, 22 allow the user to apply more torque to the container without the application of the current in the inward force to compress the casing 19.
In one alternative embodiment, be gripping surface, such as giving in to capture the surface 20 can consist of an adhesive label attached to the casing 19 of the container on which the label has a textured surface. If required, a layer of printing ink can be formed over the textured surface of the label.
In one case, application or use of the cover 10 has a thread 17 on the inner surface of the part 12, which allows you to remove the cover 10 from the housing 19, which has mating threads (not shown), p is the means of turning or rotation of the cover 10 in a counterclockwise direction, as shown by the arrow 18 in figure 4.
For a person skilled in the art it is obvious that the cover of the present invention provides advantages and has features that are missing in the known containers. For example, the cover of the present invention includes a thick outer layer of soft material, which forms a convenient and amenable to capture surface. Additional preferred characteristic cover of the present invention is that the outer layer sufficiently firmly connected c lower hollow cylindrical portion, for example, through the formation of intermolecular bonds, resulting in preventing slippage of the outer layer relative to the bottom of the hollow cylindrical part of the opening or closing of the container. The presence of measurable capture surfaces with a high coefficient of friction on the body of the container allows the user to hold the body of the container in a fixed position relative to the cover to counter the torque applied to the housing by tightening the cover on the case and the unscrewing of the cap from the housing. As a result, the container of the present invention is easier to open and close than the known containers.
