Description

  The present invention relates to a cooking pan that accommodates an object to be cooked and cooks the object to be cooked.

  Cooking pans that house cooked foods such as vegetables and meat and cook by heating are widely used. As such a cooking pan, it is needless to mention the prior art document, and a cooking pan having a pan body that forms a storage space for an object to be cooked and a pan lid that covers the storage space is known. The pot lid covers the upper part of the accommodation space by abutting with the upper end of the pot body on the lower surface.

  In such a cooking pan, the upper space of the pan body and the lower surface of the pan lid are brought into close contact with each other to cover the housing space, thereby improving the airtightness of the housing space. As a result, the pressure in the accommodation space can be increased moderately during cooking and cooking can be completed in a short period of time, or steam generated by evaporation of moisture contained in the food can be used for cooking. It becomes.

  However, in such a conventional cooking pan, when the pressure in the accommodation space rises excessively and the pan lid is pushed up, the liquid is foamed from the gap formed between the pan lid and the pan body. There is a problem that the so-called “spilling out” is noticeably generated.

  Further, steam is discharged from a gap formed between the raised pot lid and the pot body. If this discharged steam is applied to the wall surface of the kitchen, the wall surface or the like may be damaged by high-temperature steam.

  This invention is made | formed in view of such a subject, The objective can control the derivation | leading-out site | part of a vapor | steam, suppressing the excessive pressure rise in accommodation space by deriving | deriving a vapor | steam. It is to provide a cooking pot.

  The present invention is a cooking pan that accommodates an object to be cooked and cooks, and extends upward from the bottom surface portion and the peripheral edge of the bottom surface portion. A pan body having a side surface portion formed with a main body-side inclined sealing surface inclined toward the bottom surface portion on the inner side, and forming a storage space for storing an object to be cooked by the bottom surface portion and the side surface portion; It has a lid-side contact surface that contacts the contact surface on the lower surface, and has a cover-side inclined seal surface that is provided along the main body-side inclined seal surface inside the cover-side contact surface, allowing the storage space to be freely attached and detached. And a pan lid covering. The body-side contact surface and the lid-side contact surface are configured to contact over the entire circumference in the initial stage of heating, and a notch is provided so that a part of the lid-side inclined seal surface is separated from the body-side inclined seal surface. Is formed. By cooking, the pan lid is lifted from the notch side, while the main body side contact surface and the lid side contact surface are in contact with each other on the opposite side of the notch, In this case, the lid side abutment surface is separated from the main body side abutment surface, so that steam is led out through the notch.

  In the present invention, since the main body-side contact surface and the lid-side contact surface are in contact in the initial stage of heating, the airtightness in the accommodation space is improved and steam is sealed. When further heat is supplied thereafter, the pressure in the accommodation space increases, but the internal pressure rises by the dead weight of the pan lid, and the state in which the steam is sealed is maintained. Since the notch is partially formed in the pan lid, when the pressure in the accommodation space is further increased, the pan lid is lifted from the notch side that is lighter than the other portions. In this state, the main body side contact surface and the lid side contact surface are kept in contact with each other on the side opposite to the notch, and on the notch side, from the main body side contact surface to the lid side contact surface. Since the steam that passes through the notch is led out to the outside from the part where the lid side contact surface is separated from the main body side contact surface, it is like a pressure cooker or rice cooker without providing a valve body Cooking with increased internal pressure due to steam is possible.

  ADVANTAGE OF THE INVENTION According to this invention, the cooking pan which can control the derivation | leading-out site | part of a vapor | steam is provided, suppressing the excessive pressure rise in accommodation space by deriving | generating a vapor | steam.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  A cooking pan 100 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. The cooking pot 100 is a cooking utensil used for cooking at a kitchen or the like, and is used by being placed on an electromagnetic cooker IH, for example, as shown in FIG. The cooking pan 100 includes a pan body 200 and a pan lid 300.

  For easy understanding, in the state during cooking shown in FIG. 1, the direction in which the pan body 200 and the pan lid 300 are aligned (that is, the vertically upward direction) is the Z direction, and the direction orthogonal to the Z direction. The description may be made using orthogonal coordinates with the X direction and the Y direction (that is, the horizontal direction). As the orthogonal coordinates, those corresponding to those in FIG. Moreover, in the case where the description is based on directions, the directions are assumed to be in the state during cooking as shown in FIG.

  The pan body 200 is formed by casting using a metal material. As shown in FIG. 2, the pan body 200 has a bottom surface portion 210 and a side surface portion 220. The bottom surface portion 210 has a disc shape, and receives heat from the lower surface thereof in contact with the electromagnetic cooker IH or the furnace. Concavities and convexities are formed on the upper and lower surfaces of the bottom surface portion 210 to enhance heat transfer performance. The side surface portion 220 is formed so as to extend upward from the peripheral edge of the bottom surface portion 210 and has an annular shape. A pair of handles 240 for the user to hold are formed on the outer surface of the side surface portion 220 so as to protrude in the Y direction and the −Y direction. An open space surrounded by the bottom surface portion 210 and the side surface portion 220 serves as a storage space 230 for storing the food F such as vegetables and meat.

  As FIG. 4 shows, the upper end part of the pan main body 200 is expanded in diameter. FIG. 4 shows an enlarged view of the A part and the B part of FIG. 2 in the cross section of the cooking pan 100. A main body side contact surface 222 is formed at the uppermost portion of the upper end of the pot main body 200. The main body side contact surface 222 is an annular surface formed by smoothing by polishing after casting. The normal direction of the main body side contact surface 222 is the Z direction.

  A main body side sealing surface 223 is formed on the inner peripheral side of the upper end portion. The main body side sealing surface 223 is an annular surface formed by smoothing by polishing after casting. The normal direction of the main body side sealing surface 223 is a substantially horizontal direction.

  The pan lid 300 is formed by casting using a metal material. A flange portion 310 that protrudes outward is formed on the periphery of the pan lid 300. The pan lid 300 covers the accommodation space 230 by the flange portion 310 coming into contact with the upper end portion of the pan body 200. As shown in FIG. 1, a pair of handles 340 for a user to grip are formed on the outer surface of the flange portion 310 so as to protrude in the Y direction and the −Y direction.

  As shown in FIGS. 3 and 4, a lid-side contact surface 311 is formed on the lower surface of the flange portion 310. The lid-side contact surface 311 is an annular surface formed by smoothing by polishing after casting.

  An annular protrusion 320 is formed on the lower surface side of the flange portion 310. The annular protrusion 320 is a protrusion having a rectangular cross section and an annular shape as a whole. The annular protrusion 320 is formed so as to protrude downward from the flange portion 310.

  A lid side sealing surface 321 is formed on the outer peripheral side of the annular protrusion 320 of the pan lid 300. The lid-side seal surface 321 is an annular surface formed by smoothing by polishing after casting. The normal direction of the lid side sealing surface 321 is a substantially horizontal direction.

  The annular projection 320 of the pan lid 300 has a notch 322 formed in a part thereof. As shown in FIG. 3, the notch 322 is formed across the width W at a position offset from the pair of handles 340. The notch 322 has a shape that is partially cut away from the lid-side sealing surface 321 of the annular protrusion 320 toward the center of the pan lid 300. In addition, a display protrusion 330 is formed on the top surface of the pan lid 300 at a position corresponding to the notch 322. As shown in FIG. 4, the display protrusion 330 is formed so as to protrude upward from the upper surface of the pan lid 300.

  The lid lid 300 formed as described above covers the accommodation space 230 from above by the lid-side contact surface 311 contacting the body-side contact surface 222 of the pan body 200 in the vertical direction. Thus, in the state where the pan lid 300 covers the accommodation space 230, the lid-side sealing surface 321 of the pan-lid 300 and the main body-side sealing surface 223 of the pan main body 200 abut in a substantially horizontal direction. The main body side contact surface 222 and the lid side contact surface 311 are in contact with each other in the vertical direction, and the main body side seal surface 223 and the cover side seal surface 321 are in contact with each other in a substantially horizontal direction. And the pot lid 300 are in close contact with each other, and the airtightness of the accommodation space 230 is enhanced.

  The user changes the position of the notch 322 by rotating the pan lid 300 so as to slide the lid-side seal surface 321 relative to the main body-side seal surface 223 and changing the posture of the pan lid 300. Can do. The user can grasp the position of the notch 322 from above using the display protrusion 330 of the pan lid 300 as a mark.

  Further, in the state where the pan lid 300 covers the accommodation space 230, the steam outlet 400 is formed as shown in FIG. The steam outlet 400 is a gap formed in advance between the notch 322 of the pan lid 300 and the main body side sealing surface 223 of the pan main body 200. The steam outlet 400 is in communication with the accommodation space 230.

  Then, the effect of the cooking pan 100 is demonstrated. When the object to be cooked F is heated by the heat supplied from the electromagnetic cooker IH, moisture contained in the object to be cooked F evaporates and steam is generated in the accommodation space 230. As described above, since the airtightness of the storage space 230 is enhanced in a state where the pan lid 300 covers the storage space 230, this steam is enclosed in the storage space 230 at the initial stage of cooking.

  Along with the supply of heat from the electromagnetic cooker IH, the steam in the accommodation space 230 is heated to increase the temperature, and the pressure increases. The pressure of the steam acts to push up the pot lid 300 from within the accommodation space 230, but the pot lid 300 resists the pressure by its own weight. Thereby, the state by which the vapor | steam was enclosed in the accommodation space 230 is maintained.

  When the steam in the storage space 230 is further heated and a force greater than the weight acts on the pan lid 300 upward by the pressure, the pan lid 300 starts to move upward. At this time, since the pan lid 300 moves so that the lid-side seal surface 321 slides with respect to the main body-side seal surface 223, the pan lid 300 is restricted from moving in the horizontal direction. Thereby, the pan lid 300 moves upward in a stable posture.

  As shown in FIG. 5, when the pan lid 300 is pushed up by the increase of the pressure P in the accommodation space 230, the lid-side contact surface 311 of the pan-lid 300 and the main-body side contact surface 222 of the pan body 200 are separated. A gap CL1 is formed between the two. 5 is an enlarged view of the A part and the B part of FIG. 2 in the cross section of the cooking pot 100 as in FIG.

  The gap CL1 communicates with the steam outlet 400 described above. Therefore, the accommodation space 230 is in a state of communicating with the outside of the cooking pan 100 through the steam outlet 400 and the gap CL1. For this reason, as shown by arrow S1, the flow path which guide | induces the vapor | steam in the accommodation space 230 outside is formed.

  On the other hand, in the parts other than the steam outlet 400, the abutment between the lid side seal surface 321 and the main body side seal surface 223 is maintained by the sliding movement of the pot lid 300 described above. For this reason, in parts other than the vapor | steam derivation | leading-out part 400, the flow path which guide | induces the vapor | steam in the accommodation space 230 outside is not formed. That is, the amount of increase in the cross-sectional area of the gap CL1 formed in the steam outlet 400 is larger than the amount of increase in the cross-sectional area of the gap formed in a portion other than the steam outlet 400.

  As described above, according to the cooking pan 100, when the pressure in the accommodation space 230 rises with cooking and the pan lid 300 is pushed up, the steam generated in the accommodation space 230 increases in cross-sectional area. The amount is positively derived from the gap CL1 formed in the steam deriving portion 400 having a relatively large amount. Therefore, according to this configuration, by deriving the vapor from the gap CL1 formed in the vapor deriving unit 400, the excessive pressure increase in the accommodation space 230 is suppressed and the spillage is suppressed. It becomes possible to control.

  In addition, in the cooking pan 100, the pan lid 300 has a notch 322 formed in a part of its lower surface, and the steam outlet 400 is formed between the notch 322 and the upper end of the pan body 200. Therefore, by changing the position of the notch 322 by changing the posture of the pan lid 300, the position of the steam outlet 400 can be changed and the steam outlet can be easily controlled.

  If such a notch is provided in the pan body 200, it is necessary to change the position of the notch by moving the pan body 200 having a relatively large weight or changing its posture. Is a heavy burden on the user. On the other hand, in the present embodiment in which the notch 322 is formed in the pot lid 300 having a relatively small weight, the burden of such work becomes light, and the steam outlet part can be easily controlled.

  In addition, in the cooking pan 100, the pan lid 300 is provided with a display protrusion 330 at a portion corresponding to the notch 322 in the upper surface thereof. According to this configuration, the user can easily grasp the position of the notch 322 formed on the lower surface of the pan lid 300 from above. Thereby, even if the user covers the storage space 230 of the pot body 200 with the pot lid 300, the user can more easily control the steam discharge site.

  The means for causing the user to grasp the position of the notch 322 is not limited to the display protrusion 330. For example, the same effect can be obtained even when the portion corresponding to the notch 322 in the upper surface of the pan lid 300 is painted or processed to indicate that the notch 322 is formed on the lower surface.

  Moreover, in the cooking pan 100, the pan body 200 has a main body side sealing surface 223 formed in the upper end portion with the substantially horizontal direction as the normal direction. The pot lid 300 has a lid-side seal surface 321 formed on the lower surface with the substantially horizontal direction as the normal direction. The cooking pan 100 is configured such that the main body side seal surface 223 and the lid side seal surface 321 are in contact with each other in a state where the main body side contact surface 222 and the lid side contact surface 311 are in contact. According to this structure, when the pressure in the accommodation space 230 rises with cooking and the pan lid 300 is pushed up, the horizontal movement of the pan lid 300 causes the main body side sealing surface 223 and the lid side sealing surface 321 to move. It is regulated by contact with. As a result, the pan lid 300 can be moved upward in a stable posture, and the steam can be actively led out in the steam lead-out section 400.

  Next, a cooking pan 100A according to the second embodiment will be described with reference to FIGS. A cooking pan 100A according to the second embodiment is a cooking utensil used for cooking at a kitchen or the like, similar to the cooking pan 100 according to the first embodiment described above, and includes a pan body 200A and a pan lid 300A. Yes. The cooking pan 100A differs from that of the cooking pan 100 in the form of contact between the pan body 200A and the pan lid 300A. Of the cooking pot 100A, the same components as those of the cooking pot 100 are denoted by the same reference numerals, and description thereof is omitted. 6 and 7 show a cross section corresponding to the II-II cross section of the cooking pan 100 shown in FIG. 1, and an enlarged view corresponding to portions A and B shown in FIG. Yes.

  As shown in FIG. 6, the pan body 200 </ b> A of the cooking pan 100 </ b> A has a main body-side contact surface 222 </ b> A formed at the upper end portion of the side surface portion 220. The main body side contact surface 222A is an annular surface formed by smoothing by polishing after casting. The normal direction of the main body side contact surface 222A is the Z direction.

  Further, a main body-side inclined seal surface 224 is formed on the inner peripheral side of the upper end portion of the pan main body 200A. The main body side inclined seal surface 224 is a surface formed by smoothing by polishing after casting, and is inclined downward toward the center portion side of the pan main body 200A.

  The pan lid 300 </ b> A of the cooking pan 100 </ b> A has a lid-side contact surface 311 </ b> A formed on the lower surface of the flange portion 310. The lid-side contact surface 311A is an annular surface formed by smoothing by polishing after casting.

  An annular protrusion 320A that protrudes downward is formed on the lower surface of the flange portion 310 of the pan lid 300A. A lid-side inclined sealing surface 324 is formed on the outer peripheral side of the annular protrusion 320A. The lid-side inclined sealing surface 324 is an annular surface formed by smoothing by polishing after casting, and is inclined downward toward the center of the pan lid 300A. The inclination angle of the lid-side inclined seal surface 324 is substantially the same as that of the main body-side inclined seal surface 224 described above.

  The annular projection 320A of the pan lid 300A has a notch 322A formed in a part thereof. The notch 322A has a shape partially cut away from the lid-side contact surface 311A of the annular protrusion 320A toward the center side of the pan lid 300A. In addition, a display protrusion 330 is formed on the upper surface of the pan lid 300A at a position corresponding to the notch 322A. The display protrusion 330 is formed so as to protrude upward from the upper surface of the pan lid 300A.

  The lid lid 300A formed as described above covers the accommodation space 230 from above by the lid side contact surface 311A contacting the main body side contact surface 222A of the pan body 200A in the vertical direction. Thus, in the state where the pan lid 300A covers the accommodation space 230, the lid-side inclined sealing surface 324 of the pan-lid 300A and the main body-side inclined sealing surface 224 of the pan main body 200A are in a direction inclined with respect to the vertical direction. Touch. The main body side contact surface 222 and the lid side contact surface 311 are in contact with each other in the vertical direction, and the main body side seal surface 223 and the lid side seal surface 321 are in contact with each other in a direction inclined with respect to the vertical direction. Thus, the pot body 200A and the pot lid 300A are in close contact with each other, and the airtightness of the accommodation space 230 is improved.

  Further, in the state where the pan lid 300A covers the accommodation space 230, a steam outlet 400A is formed as shown in FIG. The steam outlet 400A is a gap formed in advance between the notch 322A of the pan lid 300A and the main body-side inclined sealing surface 224 of the pan main body 200A. The steam outlet 400 is in communication with the accommodation space 230.

  Then, the effect of cooking pan 100A is explained. When the object to be cooked F (see FIG. 1) is heated by the heat supplied from the electromagnetic cooker IH (see FIG. 2), the moisture contained in the object to be cooked F evaporates and steam is generated in the accommodation space 230. To do. As described above, since the airtightness of the storage space 230 is enhanced in the state where the pan lid 300A covers the storage space 230, this steam is enclosed in the storage space 230 at the initial stage of cooking.

  When the steam in the storage space 230 is heated and the temperature rises and the pot lid 300A is pushed up by the increase in pressure P, the pot lid 300A moves upward as shown in FIG. At this time, the lid side contact surface 311A of the pan lid 300A is in the X direction in which the steam outlet 400A is formed while the end portion on the −X direction side is in contact with the main body side contact surface 222A of the pan body 200A. The side end portion is separated from the main body side contact surface 222. Thus, a gap CL2 is formed between the lid-side contact surface 311A and the main body-side contact surface 222A at the end portion on the X direction side.

  This gap CL2 communicates with the steam outlet 400A. Therefore, the accommodation space 230 is in a state of communicating with the outside of the cooking pan 100A through the steam outlet 400A and the gap CL2. For this reason, as shown by arrow S2, the flow path which guide | induces the vapor | steam in the accommodation space 230 outside is formed.

  On the other hand, even if a gap is formed between the lid-side contact surface 311A and the main-body-side contact surface 222A at a portion other than the steam lead-out portion 400A, the size is larger than the gap CL2 formed in the steam lead-out portion 400A. Will also be small. That is, the amount of increase in the cross-sectional area of the gap CL2 formed in the steam outlet portion 400A is larger than the amount of increase in the cross-sectional area of the gap formed in a portion other than the steam outlet portion 400A.

  As described above, in the cooking pan 100A, the pan body 200A has the main body-side inclined sealing surface 224 that is inclined downward toward the center portion side of the pan main body 200A on the inner peripheral side of the upper end portion. Moreover, the lid lid 300 </ b> A has a lid-side inclined sealing surface 324 that is inclined downward toward the center of the pan lid 300 </ b> A on the outer peripheral side of the lower surface. The cooking pan 100 </ b> A is configured such that the main body side inclined seal surface 224 and the lid side inclined seal surface 324 are in contact with each other in a state where the main body side contact surface 222 </ b> A and the lid side contact surface 311 </ b> A are in contact. .

  According to this configuration, the pan lid 300 </ b> A comes into contact with the main body side inclined seal surface 224 at the lid side inclined seal surface 324. Both the main body side inclined sealing surface 224 and the lid side inclined sealing surface 324 are formed so as to be inclined downward toward the central portion side. Therefore, when the user covers the upper part of the accommodation space 230 with the pan lid 300A, the position of the pan lid 300A is adjusted by the inclination of the main body side inclined seal surface 224, and the pan lid 300A is arranged at the center of the pan main body 200A. It becomes easy. Thereby, it becomes possible to reliably derive steam from the steam outlet section 400A as the pan lid 300A moves upward.

  Next, a cooking pan 100B according to the third embodiment will be described with reference to FIGS. A cooking pan 100B according to the third embodiment is a cooking utensil used for cooking at a cooking place or the like, similar to the cooking pan 100 according to the first embodiment described above, and includes a pan body 200B and a pan lid 300B. Yes. The cooking pan 100 </ b> A differs from that of the cooking pan 100 in the form of contact between the pan body 200 </ b> A and the pan lid 300. Of the cooking pot 100B, the same components as those of the cooking pot 100 are denoted by the same reference numerals, and description thereof is omitted. 8 and 9 show a cross section corresponding to the II-II cross section of the cooking pan 100 shown in FIG. 1, and an enlarged view corresponding to portions A and B shown in FIG. Yes.

  As shown in FIG. 8, the pan body 200 </ b> B of the cooking pan 100 </ b> B has a main body side contact surface 222 </ b> B formed at the upper end portion of the side surface portion 220. The main body side contact surface 222B is a surface formed by smoothing by polishing after casting, and is inclined downward toward the center side of the pan main body 200B.

  Further, an annular protrusion 320B that protrudes downward is formed on the lower surface side of the flange portion 310 of the pan lid 300B. A lid-side contact surface 311B is formed on the outer peripheral side of the annular protrusion 320B. The lid-side contact surface 311B is an annular surface formed by smoothing by polishing after casting, and is inclined downward toward the center portion side of the pan lid 300B. The inclination angle of the lid side contact surface 311B is substantially the same as the main body side contact surface 222B described above.

  The annular projection 320B of the pan lid 300B has a notch 322B formed in a part thereof. The notch 322B has a shape partially cut away from the outer peripheral side of the annular protrusion 320B toward the center of the pan lid 300B. In addition, a display protrusion 330 is formed on the upper surface of the pan lid 300B at a position corresponding to the notch 322B. The display protrusion 330 is formed so as to protrude upward from the upper surface of the pan lid 300B.

  The pan lid 300B formed as described above has its lid-side contact surface 311B in contact with the main body-side contact surface 222B of the pan main body 200B in a direction inclined with respect to the up-down direction. Cover from above.

  Further, in a state where the pan lid 300B covers the accommodation space 230, a steam outlet 400B is formed as shown in FIG. The steam outlet 400B is a gap formed in advance between the notch 322B of the pan lid 300B and the main body side contact surface 222B of the pan main body 200B. The steam outlet 400B communicates with the accommodation space 230.

  In addition, a gap CL3 is formed in advance between the lower surface of the flange portion 310 and the upper end portion of the side surface portion 220, and this gap CL3 communicates with the steam outlet portion 400B. That is, in the cooking pan 100B according to the third embodiment, as shown by the arrow S31, the steam communicates with the outside of the cooking pan 100B from the inside of the accommodation space 230 through the steam outlet 400B and the gap CL3, and guides the steam to the outside. A flow path is formed in advance.

  Then, the effect of the cooking pan 100B is demonstrated. When the object to be cooked F (see FIG. 1) is heated by the heat supplied from the electromagnetic cooker IH (see FIG. 2), the moisture contained in the object to be cooked F evaporates and steam is generated in the accommodation space 230. To do. As described above, in the cooking pan 100B, a flow path that guides the steam in the accommodation space 230 to the outside via the steam outlet 400B is formed in advance. Accordingly, at the initial stage of cooking, the steam in the accommodation space 230 is guided to the outside at a relatively small flow rate, as indicated by the arrow S31.

  When the steam in the accommodation space 230 is heated and the temperature rises, and the pot lid 300B is pushed up by the increase in pressure P, the pot lid 300B moves upward as shown in FIG. At this time, the lid side contact surface 311B of the pan lid 300B is in the X direction in which the steam outlet portion 400B is formed while the end portion on the −X direction side is in contact with the main body side contact surface 222B of the pan body 200B. The end on the side is further away from the main body side contact surface 222B. As a result, the gap CL3 at the end on the X direction side is further increased. For this reason, as indicated by an arrow S32, the cross-sectional area of the flow path that guides the steam from the accommodation space 230 to the outside increases, and the flow rate of the derived steam increases.

  On the other hand, even if a gap is formed between the lid-side contact surface 311B and the main-body-side contact surface 222B at a portion other than the steam outlet 400B, the size is larger than the gap CL3 formed in the steam outlet 400B. Will also be small. That is, the amount of increase in the cross-sectional area of the gap CL3 formed in the steam outlet portion 400B is larger than the amount of increase in the sectional area of the gap formed in a portion other than the steam outlet portion 400B.

  As described above, in the state where the pan lid 300B covers the accommodation space 230, the flow path for guiding the steam to the outside is formed in advance. By appropriately setting the size of the flow path, it is possible to adjust the pressure in the accommodation space 230 and reliably suppress an excessive increase in pressure.
