Detailed Description

For a better understanding of the present invention, embodiments thereof will be described in detail below with reference to the accompanying drawings, wherein like reference numerals represent like parts. It should be understood that the described embodiments are merely examples and are not intended to limit the scope of the invention. Modifications and variations may be made to the described embodiments while remaining within the scope of the invention while understanding the principles of the invention.

Fig. 1 and 2 show a specific embodiment of the present invention, wherein the bottle opener comprises a handle 1 and a limiting portion 2 connected to the handle, the limiting portion 2 comprises a limiting plate 23 and a limiting hole 21 defined by the inner side of the limiting plate, the inner side 231 of the limiting plate is provided with a limiting tooth 22, the limiting plate 23 comprises a notch 3 extending from the inner side 231 to the outer side 232, and the size of the notch 3 enables the pipeline connected to the bottle cap to cross the notch 3 along the direction of the cross section of the pipeline.

The handle 1 and the stopper portion 2 may be integrally formed as shown in fig. 1 and 2. In other embodiments, the handle 1 and the stop 2 may also be manufactured separately as two separate parts and then rigidly connected together by means known in the art.

The handle 1 and the restriction plate 23 may be made of the same material or different materials. The material of which the handle 1 and the limit plate 23 are made may be selected from metallic materials such as stainless steel, aluminum, etc., and may also be selected from non-metallic materials such as organic materials having suitable hardness and rigidity, such as organic glass.

The handle 1 and the restriction plate 23 may have the same thickness or may have different thicknesses. The size (e.g., length, width and thickness) of the handle 1 is not particularly limited as long as it is suitable for grasping by hand and easy to handle. The thickness of the stopper plate 23 and the width from the inner portion 231 to the outer portion 232 are not particularly limited as long as they are easy to handle and are not easily deformed when the bottle cap is twisted. The stopper plate 23 does not necessarily have a uniform thickness in its width direction, and may become thinner gradually from the inner side 231 to the outer side 232, for example.

The shape and size of the stopper hole 21 depends on the shape and size of the bottle cap intended to be opened by the bottle opener. In one embodiment, the limiting hole 21 is circular according to the shape of the bottle cap. Because the shape and the size of spacing hole 21 and the shape and the size phase-match of bottle lid, when covering spacing hole 21 on the bottle lid, spacing tooth 22 can mesh with the anti-skidding tooth of the lateral wall of bottle lid for spacing portion 2 and bottle lid chucking and can not mutual displacement, thereby when twist grip 1, can drive the bottle lid rotatory, open or cover the tight bottle lid. In a particularly preferred embodiment, the limiting aperture 21 is circular.

The limiting teeth 22 are matched with the anti-slip teeth on the outer side wall of the bottle cap, so that when the limiting hole 21 is sleeved on the bottle cap, the limiting teeth 22 can be meshed with the anti-slip teeth. In one embodiment, the spacing teeth 22 are ribs extending in the axial direction of the spacing hole 21. The axial direction refers to a normal direction of the limiting hole 21, that is, a direction perpendicular to a plane in which the limiting hole 21 is located. In the top view shown in fig. 1, the axial direction is the direction perpendicular to the plane of the paper.

The number of the stopper teeth 22 is not particularly limited. For example, the number of spacing teeth 22 may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. In one embodiment, the number of spacing teeth 22 is 4. In another embodiment, the number of spacing teeth 22 is 3.

The limit teeth 22 may be evenly distributed on the inner side 231 of the limit plate 23. Of course, as will be understood by those skilled in the art, the non-uniform distribution of the stopper teeth 22 on the inner portion 231 of the stopper plate 23 is also included in the protection scope of the present invention as long as the function of opening the bottle cap can be achieved.

The stop teeth 22 may be symmetrically distributed with respect to the axial symmetry line of the stop hole 21. The axial symmetry line of the limiting bore 21 can easily be determined by a person skilled in the art. For example, when the limiting hole 21 is a circular limiting hole 21, an axis perpendicular to the circular cross section at the center of the circular cross section of the limiting hole 21 is an axial symmetry line of the limiting hole 21. Of course, as will be appreciated by those skilled in the art, the asymmetrically distributed stopper teeth 22 are also included in the scope of the present invention as long as the function of opening the bottle cap is achieved.

For the bottle cap connected with a pipeline, for example, a two-way feeding bottle cap or an inoculation bottle cap with a complex pipeline and filter structure, when a similar bottle opener without a notch is adopted, the pipeline needs to be straightened, then the pipeline passes through a limiting hole of the bottle opener from the free tail end of the pipeline, the bottle opener is moved to the position above the bottle cap, the limiting hole of the bottle opener can be sleeved on the bottle cap, the bottle cap is unscrewed, and after the operation is completed and the bottle cap is screwed again, the bottle opener is withdrawn along the pipeline, so that the operation is very complicated. If the other end of the pipeline is connected to, for example, another piece of equipment, it needs to be detached from the equipment first, which further increases the operational inconvenience and brings about a safety hazard. If the other end of the pipeline is not allowed to be disassembled, the bottle opener in the prior art cannot be used, and only a manual bottle opening method which is time-consuming, labor-consuming and unsafe can be adopted. Now, according to an embodiment of the present invention, a notch 3 extending from the inner side 231 to the outer side 232 is provided on the stopper plate 23. Through this gap 3, the line connected to the cap can pass directly across the gap without passing through the free end of the line. Like this, operating personnel need not carry out extra processing to the pipeline, need not change the position of pipeline even, can overlap spacing hole 21 on being connected with the bottle lid of pipeline. Adopt the utility model discloses a bottle-opener can save time greatly. According to the inventor's experimental statistics, it takes 1-3 minutes to unscrew a bottle lid by hand, it takes 0.5-1 minutes to unscrew a bottle lid with a similar bottle opener without a notch, and it only needs 2-5 seconds to unscrew a bottle lid with the bottle opener of the utility model, and efficiency is improved tremendously.

The size of the notch 3 is not particularly limited as long as the line connected to the cap is made to cross the notch 3 in the direction of the cross section of the line. For example, the minimum dimension of the notch 3 may be the smallest cross-sectional dimension of a line that is typically connected to the cap of a serum bottle, e.g. for a round line, it is the outer diameter of the line. The notch 3 may suitably be made larger for ease of handling and improved serviceability. For example, the notch 3 is typically no more than one quarter of the circumference of the retainer plate 23. For example, the indentation 3 may be one fifth, or one sixth, or one eighth, or one tenth, etc. of the circumference of the limit plate 23. As can be appreciated by the person skilled in the art, larger indentations 3 are also included within the scope of the invention.

The position of the notch 3 is not particularly limited. For example, in the specific example shown in fig. 1 and 2, the notch 3 is within an arc of 90 degrees to 180 degrees of the circumference of the circular stopper hole 21 in the counterclockwise direction, starting from the intersection point of the axis of symmetry of the handle 1 and the circumference of the circular stopper hole 21 (at the rightmost stopper tooth 22 in the drawing). As can be appreciated by those skilled in the art, other positions of the notch 3 are also included in the scope of the present invention.

The bottle opener of the utility model is particularly suitable for serum bottles which generate negative pressure in the bottle after high-temperature and high-pressure sterilization and are connected with pipelines on the bottle caps. As will be appreciated by those skilled in the art, the present invention is described with reference to a serum bottle cap for illustrative purposes only. The utility model discloses a bottle-opener can be applied to any container that has negative pressure, is connected with the pipeline on the bottle lid in the bottle. The bottle opener of the utility model can be produced according to the specification of the cover of the container in industry. The bottle cap or the cap can be a rotary cap, namely a cap which is unscrewed and screwed by rotation. It goes without saying that the bottle opener of the present invention can be used not only to open the bottle cap, but also to close the bottle cap.

As will be appreciated by those skilled in the art, the bottle opener of the present invention is equally applicable to bottles without negative pressure and/or without connecting lines on the lid. Therefore, the bottle opener of the utility model has wider application range.

The utility model discloses a bottle-opener application scope is wider, both can be used to ordinary serum bottle lid, also can be used to two-way or other bottle lids that lead to more.

For a supplement bottle or an inoculation bottle with a difficult bottle cover due to negative pressure and thermal expansion in the bottle, a traditional manual method is adopted, an operator with small strength usually has difficulty in unscrewing the bottle cover, needs to seek help of other people, or can unscrew after multiple attempts, and unscrewing one bottle cover usually takes 1-3 minutes. If the bottle opener in the prior art is adopted, the bottle opener cannot be directly moved downwards from the upper part of the bottle cap to be meshed with the bottle cap due to the limitation of the pipeline, the pipeline is inserted into the limiting hole from the tail end of the pipeline after the pipeline is additionally straightened, the pipeline is required to be penetrated out of the limiting hole again after the bottle cap is unscrewed, and the process of unscrewing one bottle cap usually takes 0.5-1 minute. By adopting the bottle opener of the utility model, the two-way pipe on the bottle cap can directly pass through the gap of the limiting hole, and only about 2-5 seconds are needed for unscrewing one bottle cap.
