DETAILED DESCRIPTION

[0022] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0023] It should be noted that, unless otherwise defined, technical terms or scientific terms used in one or more embodiments of the present application should be understood as their common meanings to those skilled in the art to which the present disclosure belongs. The terms "first", "second" and the like used in one or more embodiments of the present application do not represent any order, number or importance, but are only used to distinguish different components.

[0024] To facilitate understanding of the bottle cap provided by the embodiments of the present application, first, the application scenario thereof is described. The bottle cap provided by the embodiments of the present application is applied to a drinking bottle used by children. The current drinking bottle can be used to hold hot drinks (such as hot water or hot milk and the like with a relatively high temperature). However, when the current drinking bottle holds hot drinks, due to the relatively high temperature in the bottle, the air pressure is relatively high, and in the moment when the bottle cap is opened, the hot drinks may be sprayed out of the water outlet pipe.

[0025] Therefore, the embodiments of the present application provide a bottle cap to improve the effect when the bottle cap is opened and improve the safety of children using the drinking bottle.

[0026] The embodiments of the present application will be described in detail below in combination with specific drawings and embodiments.

[0027] Referring to FIG. 1 and FIG. 2, FIG. 1 shows a bottle cap in use according to an embodiment of the present application, and FIG. 2 shows a sectional view of a drinking bottle. The bottle cap 100 according to an embodiment of the present application is used in a drinking bottle, and is sealingly connected to the bottle body 200 of the drinking bottle to form a sealed space for containing hot drinks. As shown in FIG. 1 and FIG. 2, the bottle cap 100 is connected to the bottle body 200 by screwing, and a sealing gasket 300 is arranged in the bottle cap 100. When assembled, the bottle cap 100 is screwed onto the bottle body 200, and the bottle body 200 is pressed against the sealing gasket 300 to seal the connection between the bottle cap 100 and the bottle body 200 by elastic deformation of the sealing gasket 300. Of course, the screwing and sealing described above are only an exemplary connection method, and the bottle cap 100 according to an embodiment of the present application can also be connected to the bottle body 200 by other connection methods, such as a snap-fit connection between the bottle cap 100 and the bottle body 200, which can also achieve stable and fixed connection.

[0028] Referring to FIG. 1 and FIG. 3, FIG. 3 shows a structural schematic diagram of a bottle cap according to an embodiment of the present application. The bottle cap 100 according to an embodiment of the present application includes a bottle cap body 110 and a flip cover 120 rotatably connected to the bottle cap body 110. The bottle cap body 110 is provided with a water outlet pipe 140, and a gas vent 130 is arranged in the bottle cap body 110. When the bottle cap 100 is connected to the bottle body 200, the bottle cap body 110 is sealingly connected to the bottle body 200, and the water outlet pipe 140 and the gas vent 130 are both in communication with the space in the bottle body 200, while the flip cover 120 is used to block the water outlet pipe 140 and the gas vent 130. In use, when a child needs to drink a drink, the flip cover 120 is opened, and the water outlet pipe 140 and the gas vent 130 are both exposed, so that the child can directly drink the drink through the water outlet pipe 140. When drinking is not needed, the flip cover 120 is closed on the bottle cap body 110, and the flip cover 120 seals the gas vent 130 and the water outlet pipe 140. At this time, the drinking bottle as a whole is sealed, and leakage does not occur during carrying, thereby improving the safety during carrying. In some examples, the water outlet pipe 140 can be connected to a straw that extends to the bottom of the bottle to facilitate drinking by the child. Of course, the straw and the water outlet pipe 140 can be separate or integrated, which is not limited in the embodiments of the present application.

[0029] Continuing to refer to FIG. 1 and FIG. 3, when the flip cover 120 is arranged, the flip cover 120 is rotatably connected to the bottle cap body 110 by a rotation shaft (in FIG. 3, the axis around which the flip cover 120 rotates is shown by reference line L2, which is the axis of the rotation shaft). As shown by the directions of the double-headed arrows in FIG. 1 and FIG. 3, the flip cover 120 rotates around the axis of the rotation shaft to achieve opening and closing.

[0030] With reference to FIG. 1 and FIG. 3, when the water outlet pipe 140 and the air vent hole 130 are arranged, the water outlet pipe 140 and the air vent hole 130 are located within the range covered by the cover 120, so that the cover 120 can seal the water outlet pipe 140 and the air vent hole 130 when the cover 120 is closed to the bottle cap body 110. In a specific arrangement, the air vent hole 130 is located on the side of the water outlet pipe 140 facing the rotation shaft. That is, the air vent hole 130 is located between the water outlet pipe 140 and the rotation shaft, and the air vent hole 130 is closer to the rotation shaft than the water outlet pipe 140. For example, as shown in FIG. 3, the reference line L1 shows the general direction of the arrangement of the water outlet pipe 140 and the air vent hole 130. As shown in FIG. 3, the air vent hole 130 is located on the side of the water outlet pipe 140 facing the rotation shaft, and the air vent hole 130 is located close to the water outlet pipe 140. When a child drinks, even if the bottle body is tilted, the risk of leakage of the beverage from the air vent hole 130 can be reduced.

[0031] When the cover 120 is counterclockwise rotated, the cover 120 is closed, and when the cover 120 is rotated to the first set position, the cover 120 is closed to the bottle cap body 110 and seals the water outlet pipe 140 and the air vent hole 130. It should be understood that at the first set position, the cover 120 can be locked so that the cover 120 can maintain stable connection with the bottle cap 100 and seal the water outlet pipe 140 and the air vent hole 130. In addition, when the cover 120 is clockwise rotated, the cover 120 is opened, and during the rotation, when the cover 120 is rotated to the second set position, the cover 120 is spaced apart from the air vent hole 130 with a gap, and the cover 120 still seals the water outlet pipe 140. That is, during the opening of the cover 120, the sealing of the air vent hole 130 is released first, and the high-pressure gas in the bottle body 200 can be discharged through the air vent hole 130 before the water outlet pipe 140 is unsealed, so that when the water outlet pipe 140 is unsealed, the air pressure in the bottle body 200 is reduced, thereby reducing the risk of beverage being sprayed from the water outlet pipe 140 due to high air pressure in the bottle body 200.

[0032] When the cover 120 is rotated to the third set position, the cover 120 presses against the water outlet pipe 140 to bend; wherein the third set position is located between the first set position and the second set position.

[0033] Through the above description, by arranging the air vent hole 130 on the side of the water outlet pipe 140 facing the rotation shaft, the air vent hole 130 is closer to the rotation shaft than the water outlet pipe 140, so that when the cover 120 is opened, the air vent hole 130 can be unsealed before the water outlet pipe 140, thereby the air pressure in the drinking bottle can be adjusted as soon as possible through the air vent hole 130, the water spraying after the water outlet pipe 140 is unsealed is reduced, and the use effect of the drinking bottle is improved. In addition, during the turning of the cover 120, the end of the cover 120 first presses against the water outlet pipe 140 to pre-bend the water outlet pipe 140, thereby facilitating the subsequent sealing of the water outlet pipe 140 by the cover 120.

[0034] Continuing to refer to FIG. 3, in the bottle cap 100 provided by the embodiments of the present application, when the water outlet pipe 140 and the air vent hole 130 are arranged, in some examples, the arrangement direction of the water outlet pipe 140 and the air vent hole 130 is perpendicular to the axis of the rotation shaft. That is, the reference line L1 in the example of FIG. 3 is perpendicular to L2. When the above arrangement is adopted, the arrangement direction of the water outlet pipe 140 and the air vent hole 130 is arranged along a direction perpendicular to the axis around which the flip cover 120 rotates, and the arrangement is arranged along the length direction of the flip cover 120, so that the width of the flip cover 120 can be reduced as much as possible. In addition, the air vent hole 130 is arranged adjacent to the water outlet pipe 140,

[0035] Referring to FIG. 3 and FIG. 4, FIG. 4 shows a structural schematic diagram of the bottle cap 100 when the flip cover 120 is closed. The air vent hole 130 provided by the embodiments of the present application is a passage for the high-pressure gas in the bottle body 200 to leak out, and the amount of leakage of the air vent hole 130 affects the efficiency of the decrease of the gas pressure in the bottle when the flip cover 120 is opened. Therefore, the air vent hole 130 provided by the embodiments of the present application adopts a hole with a large air flow effect. For example, in some examples, the air vent hole 130 adopts a stepped hole or a tapered hole. As shown in FIG. 4, the air vent hole 130 adopts a tapered hole structure in the example of FIG. 4, and the larger end of the air vent hole 130 is the air inlet end, and the smaller end is the air outlet end. When the high-pressure gas in the bottle body leaks out, the larger opening end can make the gas flow faster into the air vent hole 130, and in addition, due to the low pressure area (relative to the high pressure in the bottle body) outside the air vent hole 130, the gas flow can quickly flow out from the air outlet end of the air vent hole 130 under the action of the pressure difference, thereby improving the efficiency of the gas leakage.

[0036] In some embodiments, the inner wall of the air vent hole 130 is an outwardly convex arc-shaped wall 131. That is, the tapered hole is a structure similar to a horn, and when this structure is adopted, the arc-shaped wall 131 can guide the gas flow, thereby reducing the resistance of the gas flow in the air vent hole 130. On the other hand, the adoption of this structure also facilitates the mold opening of the air vent hole 130 during preparation. When the arc-shaped wall 131 is formed, the curvature of the arc-shaped walls 131 on the opposite sides can be different to increase the guiding effect in different directions.

[0037] Of course, when the air vent hole 130 adopts a stepped hole, the larger end of the air vent hole 130 is also the air inlet end, and the smaller end of the air vent hole 130 is the air outlet end, and the principle is similar to that of the tapered hole, which will not be described here. It should be understood that when a stepped hole is adopted, the stepped surface is a guiding surface to reduce the resistance of the gas flow in the air vent hole 130.

[0038] It should be understood that the air vent hole 130 provided by the embodiments of the present application is not limited to the above-mentioned examples of the stepped hole or the tapered hole, and other holes that can increase the gas flow can also be applied to the embodiments of the present application, such as a straight hole with a larger diameter or other types of special-shaped holes.

[0039] With reference to FIGS. 3 and 4, in some embodiments, the side wall of the air vent 130 and the water outlet pipe 140 are integrated. That is, the air vent 130 and the water outlet pipe 140 are integrally manufactured by a mold during manufacturing. As shown in FIG. 4, the side wall of the air vent 130 and the side wall of the water outlet pipe 140 are integrated, and the air vent 130 and the water outlet pipe 140 are integrally manufactured by the mold. When the cap body 110 is assembled, the first assembly hole and the second assembly hole are provided on the flip 120. During assembly, the water outlet pipe 140 is arranged in the first assembly hole, and the side wall of the air vent 130 is arranged in the second assembly hole. The integrated structure of the water outlet pipe 140 and the air vent 130 is fixed to the cap body 110 by clamping. As an example shown in FIG. 4, the part of the water outlet pipe 140 inside the cap body 110 is fixed to the cap body 110 by clamping, and the side wall of the air vent 130 is directly clamped in the second assembly hole. Of course, in addition to the clamping mode shown in FIG. 4, the water outlet pipe 140 and the air vent 130 can be fixed to the cap body 110 by other clamping modes.

[0040] When the first assembly hole and the second assembly hole are provided, the shape of the first assembly hole and the second assembly hole matches the shape of the water outlet pipe 140 and the air vent 130, and the arrangement position of the first assembly hole and the second assembly hole is determined according to the position of the water outlet pipe 140 and the air vent 130. For reference, the position of the water outlet pipe 140 and the air vent 130 is limited above, and will not be described here.

[0041] It should be understood that when the air vent 130 and the water outlet pipe 140 are assembled into the first assembly hole and the second assembly hole, the air vent 130 and the water outlet pipe 140 block and seal the first assembly hole and the second assembly hole to avoid gaps at the connection. The above blocking includes but is not limited to interference fit between the air vent 130 and the water outlet pipe 140 and the corresponding assembly hole to seal by deformation of the side wall of the air vent 130 and the water outlet pipe 140; the structure of the air vent 130 and the water outlet pipe 140 inside the cap body 110 abuts against the inside of the cap body 110 to form a seal.

[0042] In some examples, the first assembly hole and the second assembly hole can be a continuous hole. Of course, the first assembly hole and the second assembly hole can also be two independent holes, and the specific setting can be set according to actual needs, which is not limited in the embodiments of the present application.

[0043] With reference to FIGS. 3 and 4, in some embodiments, the bottle cap body 110 is provided with an annular protrusion 112, which encloses a region 111 for accommodating the water outlet pipe 140 and the air vent hole 130. The annular protrusion 112 has an overall shape of an ellipse or an approximately elliptical annular structure. The region 111, where the water outlet pipe 140 and the air vent hole 130 are arranged, is separated from other regions by the annular protrusion 112. When the flip cover 120 is closed to the bottle cap body 110, the flip cover 120 is closed to the annular protrusion 112 and seals the air vent hole 130 and the water outlet pipe 140.

[0044] In some embodiments, the flip cover 120 is locked by cooperating with the annular protrusion 112 when the flip cover 120 is closed to the bottle cap body 110. For example, the flip cover 120 is provided with a clamping protrusion 121. When the flip cover 120 is rotated to a first set position, the flip cover 120 is clamped to the annular protrusion 112, and the clamping protrusion 121 is clamped to the edge of the annular protrusion 112. As shown in FIGS. 3 and 4, the edge of the flip cover 120 is provided with the clamping protrusion 121. When the flip cover 120 is closed to the bottle cap body 110, the flip cover 120 wraps the annular protrusion 112 on the bottle cap body 110, and the clamping protrusion 121 of the flip cover 120 is clamped and fixed to the annular protrusion 112, thereby locking the flip cover 120, so that the flip cover 120 can maintain the sealing state of the water outlet pipe 140 and the air vent hole 130 when it is closed.

[0045] In some embodiments, the bottle cap body 110 has a concave design at the part of the annular protrusion 112, so as to increase the space between the flip cover 120 and the bottle cap body 110 when the flip cover 120 is closed to the bottle cap body 110.

[0046] With reference to FIGS. 3 and 4, when the flip cover 120 is sealed and cooperated with the water outlet pipe 140 and the air vent hole 130, the flip cover 120 is provided with an outward protruding structure for sealed cooperation with the water outlet pipe 140 and the air vent hole 130. The structure of the flip cover 120 for sealed cooperation with the air vent hole 130 and the water outlet pipe 140 is described below.

[0047] First, the sealed cooperation of the air vent hole 130 is described. The flip cover 120 is provided with a sealing column 122, which is located at the inner side of the flip cover 120 (the side of the flip cover 120 facing the bottle cap body 110 when the flip cover 120 is closed to the bottle cap body 110). When the flip cover 120 is closed to the bottle cap body 110, the sealing column 122 is pressed against the air outlet end of the air vent hole 130, so as to seal the air vent hole 130 when the flip cover 120 is closed. The sealing state is shown in FIG. 4. It should be understood that the above-mentioned sealing pressing can be achieved by pressing the end face of the air outlet end of the air vent hole 130 with the sealing column 122, or by inserting the sealing column 122 into the air vent hole 130 to block the air outlet end. Of course, the sealing column 122 can also press against the end face of the air outlet end and be inserted into the air vent hole 130 at the same time.

[0048] In the sealing of the water outlet pipe 140, the cover 120 is provided with an abutting protrusion 123 on the inner side of the cover 120, which is used to abut against the water outlet pipe 140 to seal it. Correspondingly, the outer wall of the side of the water outlet pipe 140 away from the rotation shaft is provided with an inner recess structure 144, which is used to define the bending direction and the bending height of the water outlet pipe 140. When the cover 120 is rotated to the third set position, the inner wall of the end of the cover 120 away from the rotation shaft abuts against the water outlet pipe 140, and the abutting protrusion 123 is spaced apart from the water outlet pipe 140 by a gap. In the process of the cover 120 continuing to flip, the inner wall of the end of the cover 120 away from the rotation shaft drives the water outlet pipe 140 to bend at the inner recess structure 144, thereby guiding the bending direction of the water outlet pipe 140, and then the abutting protrusion 123 abuts against the water outlet pipe 140. When the cover 120 is located at the first set position, the abutting protrusion 123 abuts between the water outlet end of the water outlet pipe 140 and the inner recess structure 144, the water outlet pipe 140 is bent at the inner recess structure 144, and the abutting position of the water outlet pipe 140 and the abutting protrusion 123 is also bent, and the water outlet end is pressed against the bottle cap body 110. In the above cooperation, the water outlet pipe 140 is folded by the pressing of the abutting protrusion 123, thereby forming a seal. In addition, the abutting protrusion 123 presses the water outlet end of the water outlet pipe 140 against the bottle cap body 110 and bends again, forming a Z-shaped bending. In the above sealing process, on the one hand, a seal is formed by the bending of the water outlet pipe 140 at the inner recess, and on the other hand, a seal is formed by the extrusion of the abutting protrusion 123 and the bottle cap body 110. Thus, the sealing effect of the water outlet pipe 140 is improved.

[0049] For convenience of description, the water outlet pipe 140 is divided into two sections with the inner recess structure 144 as the reference point, which are the first water outlet section 141 and the second water outlet section 142, wherein the water outlet end of the water outlet pipe 140 is located in the first water outlet section 141, and the second water outlet section 142 is connected with the bottle cap body 110. Referring to FIG. 3, when the water outlet pipe 140 is unfolded, the first water outlet section 141 and the second water outlet section 142 are inclined to the side away from the rotation shaft (the axis L1) of the axis of the bottle cap body 110, on the one hand, to facilitate children to drink, and on the other hand, to facilitate the abutting protrusion 123 to press the first water outlet section 141 to bend. As shown in FIG. 4, when the water outlet pipe 140 is sealed, the first water outlet section 141 and the second water outlet section 142 are folded to achieve sealing. In addition, the abutting protrusion 123 also presses the first water outlet section 141 to bend, and increases a seal by the extrusion of the abutting protrusion 123 and the bottle cap body 110.

[0050] In some embodiments, a sealing protrusion 143 is further provided in the water outlet pipe 140, which is used to seal the folding part of the water outlet pipe 140 to enhance the sealing effect. For example, the sealing protrusion 143 is provided on the inner wall of the water outlet pipe 140 near the rotation shaft. When the first water outlet section 141 is folded against the second water outlet section 142, the sealing protrusion 143 abuts against the opposite side wall, thereby further enhancing the sealing effect.

[0051] It should be understood that the abutting protrusion 123 and the sealing column 122 can be integrated with the cover 120, or the abutting protrusion 123 and the sealing column 122 can be separate from the cover 120, and the abutting protrusion 123 and the sealing column 122 can be fixed to the cover 120 by adhesion.

[0052] In addition, when the cover 120 seals the air vent hole 130 and the water outlet pipe 140, the height of the folding part of the first water outlet section 141 and the second water outlet section 142 is higher than the height of the air vent hole 130, i.e. the height of the sealing position of the water outlet pipe 140 is higher than the height of the sealing position of the air vent hole 130. Therefore, when the cover 120 is opened, even if the air vent hole 130 is closer to the rotation shaft than the water outlet pipe 140, due to the difference in the sealing height, the air vent hole 130 can still be sealed first, and then the water outlet pipe 140 is sealed.

[0053] Referring to FIGS. 4, 5 and 6, FIGS. 4-6 show the schematic diagrams of the cover 120 being rotated from the closed state to the open state in the counterclockwise direction. During the opening process, the cover 120 is rotated in the direction shown by the arrow in the schematic diagrams of FIGS. 4-6. FIG. 5 shows the schematic diagram of the cover 120 in the open state, and FIG. 6 shows the schematic diagram of the cover 120 in the fully open state.

[0054] Firstly, referring to Fig. 4, in the state that the cover 120 is closed, the sealing column 122 and the abutting protrusion 123 of the cover 120 seal the air vent 130 and the water outlet pipe 140 respectively. Then the cover 120 is opened, and the cover 120 is rotated counterclockwise, and the sealing of the air vent 130 is released first, and the high-pressure gas in the bottle body 200 can be discharged through the air vent 130. At this time, the water outlet pipe 140 is still in the sealed state. Continue to rotate the cover 120 to the state shown in Fig. 5, and in this state, the water outlet pipe 140 is also unsealed. In this state, the child can drink beverages using the water outlet pipe 140. However, since the cover 120 is not limited in the state shown in Fig. 5, the cover 120 is easy to knock the child. Therefore, the cover 120 is limited in the bottle cap 100 provided in the embodiment of the application. As shown in Fig. 6, the cover 120 provided in the embodiment of the application can also be locked in the fourth set position. When the cover 120 is located in the fourth set position, the cover 120 abuts against the bottle cap body 110, and the position where the cover 120 abuts against the bottle cap body 110 is located on the side away from the water outlet pipe 140. That is, in the state shown in Fig. 6, when the cover 120 is locked in the fourth set position, the cover 120 abuts against the bottle cap body 110.

[0055] In order to conveniently describe the state of the cover 120, the outer side surface 125 of the cover 120 is defined. The outer side surface 125 refers to the side exposed when the cover 120 is closed to the bottle cap body 110. That is, the abutting protrusion for pressing the water outlet pipe 140 is arranged on the inner side of the cover 120, and the side of the cover 120 away from the abutting protrusion 123 is the outer side surface 125.

[0056] Referring to Figs. 4 to 6, the bottle cap body 110 is provided with a connecting protrusion 113, which is used to rotate with the cover 120. Specifically, the rotating shaft is fixedly connected with the cover 120 and is inserted into the connecting protrusion 113 to be rotatably connected with the connecting protrusion 113, so as to realize the rotation of the cover 120 with the bottle cap body 110.

[0057] When the cover 120 is locked in the fourth set position, the side of the connecting protrusion 113 away from the air vent 130 is provided with a limiting protrusion 114, which protrudes outward from the connecting protrusion 113. When the cover 120 is rotated to the fourth set position, the limiting protrusion 114 abuts against the cover 120, and the outer side surface 125 of the cover 120 abuts against the bottle cap body 110. That is, the limiting protrusion 114 and the bottle cap body 110 jointly lock the cover 120. In this state, the cover 120 can be fixed, and even if the bottle body 200 is rotated, the cover 120 can remain in the fourth set position, thereby improving the safety of the child when using the bottle cap 100.

[0058] Referring to FIG. 3 and FIG. 6, in order to ensure the stability of the flip cover 120 during rotation and locking, two feet 126 are arranged at the end of the flip cover 120 close to the connecting protrusion 113, and the two feet 126 are arranged on the opposite sides of the connecting protrusion 113, i.e. the two feet 126 are arranged along the axis direction of the rotation shaft, and the two feet 126 sandwich the limiting protrusion 114. The rotation shaft is a column structure arranged on each foot 126, and the column structure is rotationally connected with the connecting protrusion 113. During assembly, the opposite sides of the connecting protrusion 113 are respectively provided with connecting holes, and the two column structures are respectively inserted into the corresponding connecting holes and can rotate in the connecting holes, so as to realize the rotation of the flip cover 120 relative to the bottle cap body 110.

[0059] When cooperating with the limiting protrusion 114, the end of the flip cover 120 close to the limiting protrusion 114 is the abutting end 124, and the abutting end 124 is located between the two feet 126, so that when abutting, the stability of the flip cover 120 can be increased by the two feet 126.

[0060] In some examples, the abutting end 124 of the flip cover 120 is thinned, i.e. the thickness of the abutting end 124 is smaller than the thickness of other parts, so that when the abutting end 124 is engaged with the limiting protrusion 114, the abutting end 124 can cross the limiting protrusion 114 by elastic deformation.

[0061] The embodiments of the present application also provide a drinking bottle, which comprises a bottle body 200 and the bottle cap 100 of any one of the above, wherein the bottle cap 100 is sealingly connected with the bottle body 200.

[0062] In the above embodiment, by arranging the air hole 130 on the side of the water outlet pipe 140 close to the rotation shaft, the air hole 130 is closer to the rotation shaft relative to the water outlet pipe 140, and when the flip cover 120 is opened, the air hole 130 can be unsealed earlier than the water outlet pipe 140, so that the air pressure in the drinking bottle can be adjusted as soon as possible through the air hole 130, the water spraying of the water outlet pipe 140 after unsealing is reduced, and the use effect of the drinking bottle is improved.

[0063] One or more embodiments of the present specification are intended to cover all such alternatives, modifications and variations falling within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent replacements, improvements and the like made within the spirit and principles of one or more embodiments of the present specification shall be included in the protection scope of the present disclosure.

[0064] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
